Contributor: Aaron Lessen, MD Educational Pearls: Point-of-care ultrasound (POCUS) is used to assess cardiac activity during cardiac arrest and can identify potential reversible causes such as pericardial tamponade Ultrasound could be beneficial in another way during cardiac arrest as well: pulse checks Manual palpation for detecting pulses is imperfect, with false positives and negatives Doppler ultrasound can be used as an adjunct or replacement to manual palpation for improved accuracy Options for Doppler ultrasound of carotid or femoral pulses during cardiac arrest: Visualize arterial pulsation Use color doppler Numerically quantify the flow and correlate this to a BP reading - slightly more complex Doppler ultrasound is much faster than manual palpation for pulse check Can provide information almost instantaneously without waiting the full 10 seconds for a manual pulse check The main priority during cardiac arrest resuscitation is to maintain quality compressions If pulses are unable to be obtained through Doppler within the 10-second window, resume compressions and try again during the next pulse check References Cohen AL, Li T, Becker LB, Owens C, Singh N, Gold A, Nelson MJ, Jafari D, Haddad G, Nello AV, Rolston DM; Northwell Health Biostatistics Unit.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Paper Summary: The Effects of Communicating Uncertainty on Public Trust in Facts and Numbers, published by AI Impacts on July 9, 2024 on LessWrong. by Anne Marthe van der Bles, Sander van der Linden, Alexandra L. J. Freeman, and David J. Spiegelhalter. (2020) https://www.pnas.org/doi/pdf/10.1073/pnas.1913678117. Summary: Numerically expressing uncertainty when talking to the public is fine. It causes people to be less confident in the number itself (as it should), but does not cause people to lose trust in the source of that number. Uncertainty is inherent to our knowledge about the state of the world yet often not communicated alongside scientific facts and numbers. In the "posttruth" era where facts are increasingly contested, a common assumption is that communicating uncertainty will reduce public trust. However, a lack of systematic research makes it difficult to evaluate such claims. Within many specialized communities, there are norms which encourage people to state numerical uncertainty when reporting a number. This is not often done when speaking to the public. The public might not understand what the uncertainty means, or they might treat it as an admission of failure. Journalistic norms typically do not communicate the uncertainty. But are these concerns actually justified? This can be checked empirically. Just because a potential bias is conceivable does not imply that it is a significant problem for many people. This paper does the work of actually checking if these concerns are valid. Van der Bles et al. ran five surveys in the UK with a total n = 5,780. A brief description of their methods can be found in the appendix below. Respondents' trust in the numbers varied with political ideology, but how they reacted to the uncertainty did not. People were told the number either without mentioning uncertainty (as a control), with a numerical range, or with a verbal statement that uncertainty exists for these numbers. The study did not investigate stating p-values for beliefs. Exact statements used in the survey can be seen in Table 1, in the appendix. The best summary of their data is in their Figure 5, which presents results from surveys 1-4. The fifth survey had smaller effect sizes, so none of the shifts in trust were significant. Expressing uncertainty made it more likely that people perceived uncertainty in the number (A). This is good. When the numbers are uncertain, science communicators should want people to believe that they are uncertain. Interestingly, verbally reminding people of uncertainty resulted in higher perceived uncertainty than numerically stating the numerical range, which could mean that people are overestimating the uncertainty when verbally reminded of it. The surveys distinguished between trust in the number itself (B) and trust in the source (C). Numerically expressing uncertainty resulted in a small decrease in the trust of that number. Verbally expressing uncertainty resulted in a larger decrease in the trust of that number. Numerically expressing uncertainty resulted in no significant change in the trust of the source. Verbally expressing uncertainty resulted in a small decrease in the trust of the source. The consequences of expressing numerical uncertainty are what I would have hoped: people trust the number a bit less than if they hadn't thought about uncertainty at all, but don't think that this reflects badly on the source of the information. Centuries of human thinking about uncertainty among many leaders, journalists, scientists, and policymakers boil down to a simple and powerful intuition: "No one likes uncertainty." It is therefore often assumed that communicating uncertainty transparently will decrease public trust in science. In this program of research, we set out to investigate whether such claims have any empirical ...

In this episode, Arnie and Fred continue their discussion of the church of Christ at Philippi. We begin by noting that the church had to combat local prejudices from the start. We look at one of those situations, but also notice that in spite of this they were able to grow rapidly and continually, both spiritually and numerically. They were successful a number of important areas. They were self-supporting, they helped support Paul as well as others that were named as Paul's helpers. Additionally, they participated in helping the needy saints in Jerusalem who were suffering from a famine there. We also talk about their support of Paul while he was incarcerated in Rome in about AD 63. In Paul's letter to them, he noted that they had selected both elders/bishops and servants/deacons to serve the congregation.  We discuss how this rapid growth and achievement was possible and what they did to accomplish it. Take about 30-minutes to listen in on our discussion. Have your Bible handy so you can verify what we are saying. There is a transcription of this Buzzsprout episode provided for your convenience.

Andrew Dickens: Don't underestimate Winston Peters in coalition talks

Heather du Plessis-Allan Drive

Once again, thanks to MMP, we're back in a state of suspension and waiting for the conclusion of coalition talks. Which for all the parties' claims- are barely progressing. And I think it's important for our collective sanity that we concentrate on what we know, rather than all the ifs, buts, maybes and reckons which we might imagine to be the case. What is it that we actually know? We know that National and ACT and NZ First are willing to form a coalition, and that's pretty much it so far. The big thing we need to do now is to get the three to meet. Now what we know about that was revealed in Winston Peters' only interview thus far, with Sean Plunket- which was held on Friday. And he said two things- he said that all three parties should meet together at the same time. Not National-ACT, then National-NZ First, then ACT-NZ First. All three, at the same time, in the same room. We can also presume that based on his telephone tag with David Seymour this weekend, he would like all of that to happen face to face. No-one on the phones, no-one on the conference call- all three walk into the room at the same time. His other thing that he said in the interview was that the nuts and bolts of the coalition deal should be negotiated by chiefs of staff, and not by the leaders. Now, those two ideas came out first thing on Friday. I mentioned this to Chris Bishop. And I actually think they're good ideas. I think the leaders should be seen entering the same room, just to show that they're seriously considering a strong, stable, united Government. At the moment, I don't even know if they're in the same city. And this is all so important that a phone call really isn't enough to nail it. The other thing I feel is that NZ First is afraid of being thought of as an afterthought. Tacked on to the end of a National-ACT agreement. They feel they're just as important as the other two players. Numerically smaller, but without them- there will be no Government. Winston Peters believes he's an equal to the other two leaders. In fact, comparing his experience to the other two, he'll probably consider himself their superior. And his standing needs to acknowledge that, because we all know he has an ego. Leaving the chiefs of staff to thrash it out is a good idea too, it means the leaders don't get sucked into all these arguments about minor details and hate each other. Then at the end of the day, they all gather for a symbolic signing- it's all how international treaties are negotiated. All the chiefs of staff do it, and then the Presidents and Prime Ministers gather together to shake and wave. So far on those two ideas mentioned- first thing on Friday, there's been no movement from National. I asked Chris Bishop about party talks on Friday, he says it's too soon to discuss. All the other debates about what jobs the various MPs get in the coalition are still way down the track, which is why I didn't believe Andrew Williams' earlier claims on Mike Hosking. Now, the really important thing in this whole process is not to underestimate Winston Peters. It's not his first rodeo, he's a lawyer. And he may not have started his own business, but he started his own party. He hired all the staff, he chose all the candidates, he did all the branding, he made all the ads and got finance for the whole thing- that's a big job, and he's been the master of the rat king needed to be a political leader since he entered Parliament 45 years ago.

May 28, 2023Luke provided his 2nd high-level overview of the progress of the Church in Jerusalem.  Luke's report was awesome.  Numerically, the church had grown rapidly, from ~1,000 people after Jesus' resurrection to ~10,000 people.  Spiritually, the Christians in Jerusalem were united in placing more value on people and less value on their possessions.  They generously provided for the financial needs of others, and some people from time to time even sold houses or land and gave the money to the needy, to the extent that “there was not a needy person among them”.  This was impressive, especially given that many of the new believers were visitors to Jerusalem who had come to celebrate Passover, got saved, decided to stay, and needed extra help.  At the same time, the Apostles preached the Gospel boldly through the power of the Holy Spirit, despite opposition from the Jewish leaders.  Finally, Luke introduced Barnabas, and shared the real-life example of his generosity.Acts 4:32-37

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.04.15.536945v1?rss=1 Authors: Cudone, E., Lower, A., McDougal, R. A. Abstract: Biophysically detailed simulations attempting to reproduce neuronal activity often rely on solving large systems of differential equations; in some models, these systems have tens of thousands of states per cell. Numerically solving these equations is computationally intensive and requires making assumptions about the initial cell states. Additional realism from incorporating more biological detail is achieved at the cost of increasingly more states, more computational resources, and more modeling assumptions. We show that for both point and morphologically-detailed cell models, the presence and timing of future action potentials is probabilistically well-characterized by the relative timings of a small number of recent synaptic events alone. Knowledge of initial conditions or full synaptic input history is not a requirement. While model time constants, etc. impact the specifics, we demonstrate that for both individual spikes and sustained cellular activity, the uncertainty in spike response decreases to the point of approximate determinism. Further, we show cellular model states are reconstructable from ongoing synaptic events, despite unknown initial conditions. We propose that a strictly event-based modeling framework is capable of representing the full complexity of cellular dynamics of the differential-equations models with significantly less per-cell state variables, thus offering a pathway toward utilizing modern data-driven modeling to scale up to larger network models while preserving individual cellular biophysics.

Friends,Artificial intelligence (AI) is finally hitting the economy and society big time. Bing's chatbot (Microsoft plans a wide release soon) is capable of long, open-ended text conversations on virtually any topic. It's caused a Times columnist to become “deeply unsettled, even frightened.” Google engineer Blake Lemoine was fired after claiming that the firm's AI model, LaMDA, is “sentient.”It's causing professors like me to wonder how to distinguish between student writing on exams and AI writing. It's causing people who track online misinformation to worry it will undermine democracy. “This is going to be the most powerful tool for spreading misinformation that has ever been on the internet,” warned Gordon Crovitz, co-chief executive of NewsGuard, which tracks online misinformation. It's causing philosophers and biologists to fret that it will eventually destroy human beings and take over the world (Hal? You still there?). But one aspect we're not talking about enough is AI's effect on work. We all know what happened when complex machines first began taking over jobs. Then mechanization replaced skilled artisans. Then automation replaced repetitive jobs that could be put into software code. Numerically controlled machine tools and robotics replaced assembly lines. More recently, big data processing has replaced much analytic work. Now comes AI — which will replace almost all professional work. At every stage, productivity (output per worker) has increased dramatically, so fewer workers have been needed to accomplish what came before. This has reduced the bargaining power of less-skilled workers to obtain high wages, while fueling the compensation of people who produce the labor-replacing technologies. We're now approaching an inflection point when the financial returns to AI's producers are heading into the stratosphere, even as professional jobs disappear. Wall Street is going nuts over AI. Venture capitalists are pouring hundreds of billions into it, driving up startup valuations. Microsoft's rally on Bing pushed its market capitalization to above $2 trillion. Alphabet's stock is expected to soar more than 20 percent on its AI investments. But after AI takes over almost all remaining jobs (including those of the venture capitalists who finance AI and the engineers who design it), what exactly will human beings be doing to make money? Or to put the matter more baldly, who will be able to afford any of the wondrous goods and services powered by AI if we no longer have incomes? My prediction: It will be the high-level professional class, including top business executives and the wizards of finance, who push for the most obvious solution: A guaranteed universal basic minimum income for everyone, financed by a tax on AI. A universal basic income could be a potential solution to ensure that individuals have a basic income to support themselves and their families. UBI is a system in which every citizen or resident of a country receives a regular, unconditional sum of money from the government, regardless of their employment status. The goal of UBI is to provide individuals with enough income to meet their basic needs, such as food, shelter, and health care.(The last paragraph, above, was generated entirely by ChatGPT.

He talks about how Shinto first started in Japan, the way of Shinto in life, and its numerous festivities and celebrations. According to Ito, Shinto can be difficult for many foreigners to understand because it is not organized in the same way as many Western religions; it does not have initiation rituals or even a specific membership. Shinto focuses on the worship of kami, numerous divinities who are believed to inhabit all things. Numerically, it is Japan's largest religion, the second being Buddhism. Most of the country's population takes part in both Shinto and Buddhist activities, especially festivals, reflecting a common view in Japanese culture that the beliefs and practices of different religions need not be exclusive.

Higgsless simulations of cosmological phase transitions and gravitational waves by Ryusuke Jinno et al. on Tuesday 11 October First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of these gravitational waves rely heavily on simulations of a Higgs field coupled to the plasma of the early Universe, the former providing the latent heat of the phase transition. Numerically, this is a rather demanding task since several length scales enter the dynamics. From smallest to largest, these are the thickness of the Higgs interface separating the different phases, the shell thickness of the sound waves, and the average bubble size. In this work, we present an approach to perform Higgsless simulations in three dimensions, producing fully nonlinear results, while at the same time removing the hierarchically smallest scale from the lattice. This significantly reduces the complexity of the problem and contributes to making our approach highly efficient. We provide spectra for the produced gravitational waves for various choices of wall velocity and strength of the phase transition, as well as introduce a fitting function for the spectral shape. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.04369v2

TRANSCRIPT (read by Kyle Stedman, with no music or effects or anything): Oh, hey, what's up, remember me? This is Kyle Stedman, host of the Bad Ideas about Writing podcast, and wow, it's been a while, right? This is a friendly in-between episode to let you know what's up. The short answer is that I've been busy and that the rest of the episodes are coming soon. I mean, you probably get it: as I record this, it's December 2021, the pandemic is still raging, and teaching this last fall felt, in some ways, harder than ever. So my original thoughts of, "Oh, I'll get to that episode soon" eventually faded into "I'll get to that episode once I'm out of survival mode?" So here I am, nearly four months after the last completed episode was posted, finally rocking and rolling and planning for the future. How about that! I do feel bad if you were relying on this podcast-slash-audiobook in a time-sensitive context like a class, but otherwise, I'm trying pretty hard not to feel too bad about the delay, because after all we all need a little grace these days. So: look for new episodes this January (or this December if I get really into it), and just don't pay too much attention to the weather updates at the end of each episode, since a couple of these were initially recorded quite a while back. Numerically, the book will be done when I record chapter 63, and chapters 1-48 are out now, on all your podcast apps. That means what, 15 more episodes? 3 or 4 months' worth? Sounds like fun, right? No big deal! And after that, that'll be it, with maybe one wrap-up reflective episode from me, or maybe not. But I'm NOT planning to keep the podcast going hardcore in some new reimagined way after I finish reading the book. If anything, I'll just find another book to read! As always, feel free to reach out: you can find my email if you search Kyle Stedman Rockford University, and I'm on Twitter @kstedman, where I'm probably posting something about Christmas movie soundtracks or Nancy Drew or how awesome my students are. See you soon—I mean, hear you soon. I mean, you'll hear me soon . . . this is complicated, avoiding visual-based metaphors, right? How about this: peace to you and your loved ones.

There is a widely shared photo from the era of the Nazi 3rd Reich. In it you see everyone ‘heiling' and saluting to the Führer except for one lone figure. Often there is a red circle drawn around this person. Pointing out the only person standing against the tide of genocide and authoritarianism. In Caste: The Origins of Our Discontents, Isabel Wilkerson opens her book by asking: “We might feel certain that, were we Aryan citizens under the Third Reich, we surely would have seen through it, would have risen above it like him, been that person resisting authoritarianism and brutality in the face of mass hysteria...But unless people are willing to transcend their fears, endure discomfort and derision, suffer the scorn of loved ones and neighbors and co-workers and friends, fall into disfavor of perhaps everyone they know, face exclusion and even banishment, it would be numerically impossible, humanly impossible, for everyone to be that man. What would it take to be him in any era? What would it take to be him now?” As Isabel Wilkerson points out, while we all may assert we would be that person, the reality is that “it would be numerically impossible, humanly impossible, for everyone to be that man.” Isabel Wilkerson's Book ‘Caste: The Origins of Our Discontents' provides an opportunity to strive to “be that man.” If there is one book you plan to read this year, it is my wish that this be amongst your top considerations. On this week's episode, I am joined by past guest's Stacey Cosden and Lloyd Wilkey to discuss and reflect upon Isabel Wilkerson's Caste. Together we share with you some of the passages, insights, ahas, and emotions that deeply impacted us. There is no way we can do the book justice in just 1 hour.

So, why am I here and why am I talking to you about the retail industry? Well, first - a little background. After graduating from Warwick University with a degree in International business back in 2000 I was trying to figure out what I wanted to do. After numerous, uninteresting interviews with consulting firms, and from previous experience on the shop floor, I knew I wasn't cut out for a career in retail management. I instead found my home in Merchandising. Numerically and creatively-led, in working with products and creating long term strategies I was afforded the opportunities to work in the states, handling 400 million dollar budgets for Talbots; from 2008 I worked on the UK high street with the Austin Reed Group and Coast; and in 2015 landed my dream job of running stationary at Paperchase (because who doesn't love stationery?) However, after 17 years, a decade of which I'd been a full-time mother, juggling the stresses of supporting a struggling industry with the demands of family life, I made the difficult but exciting decision to step back, let go and start my own business. It was at this point that I began researching why the retail industry was indeed struggling.  From identifying the effects of the 2008 financial crisis on consumers to studying changes in technology I came to understand that my expertise and experience in merchandising uniquely positioned me to assist clients in an ever-changing world. And that's why I'm here - to share my insights with you! Whether you're operating out of an office, on Etsy, Facebook Marketplace, Instagram or at a market stall you are an important and growing part of the retail industry and I want to help you to not only make money, to trade profitably, control stock and to price correctly - but to plan and strategise for the future and become a resilient retail business!

NachDaily: 5 Minute Perek of Tanach covering the entire Navi. Sefer Yehoshua, Shoftim, Shmuel, Melachim, Yeshaya, Yirmiya, Ye

Tehilim Perek 119: Letter KUF Hello everybody, I’m Rabbi Shaya Sussman, covering the entire TANACH one perek at a time. Today’s Nach Daily will discuss the letter KUF. Kuf represents a heKuf, border, a passageway, a point of integration and Kedusha, holiness. As the eye of a needle is called the Kof Hamchat, this all points towards transitioning and moving to another, higher plane. Kuf comes after the latter Tzaddik because Kedusha, holiness, comes only after one has reached the level of a Tzaddik. After we have worked on ourselves, and even refrained from some things that are permissible, we can begin to receive and experience the higher level of Kedusha represented by the letter Kuf, transitioning from one level to another. This transitioning of levels can also work in the negative. As the passuk says, “lo t’hey Kadesha m’bnos Yisrael, there shouldn’t be a harlot from among the daughters of Israel. We find here that a zona, harlot,is called a Kadesha, which means that this particular woman descended to a lower level by separating herself in a lowly manner. Both the word for Kedusha, holiness, and Kadesha, a harlot, share the same etymology. They both stem from the letter Kuf, a point of integration or moving from level to level in either direction, for good or bad. The first time that the letter Kuf is used in the beginning of a word in the Torah is when it says, “VayiKra Elokim la’or yom, v’lachoshech Kara lyla, God called the light day and the darkness night.” The act of giving something a name is what causes it to transition and become something of permanence. When Hashem called the light, “Day, the name became official. When He called the darkness, “Night, the night also became a thing of permanence. It transitioned from a non-fact to a fact. This points towards the meaning of the letter Kuf, which is a transitional letter by definition as it’s the force of moving from one point to another. Kof means a monkey. The connection here is that it appears to look as if humans came from monkeys. Monkeys would then be like an intermediate or transition from humans. Please don’t get me wrong—we did not evolve from monkeys! Conceptually, however, monkeys appear to look like humans and Kof, from the letter Kuf, looks like a transitional point between humans and animals. The word for marriage is called Kedushin because in marriage a woman and man integrate and join with each other to become a new entity. Kuf is the point of integration. The shape of the letter Kuf has two openings representing the ability to go up or down levels. It should be noted, however, that the bottom opening of the Kuf gets smaller, as if bent inwards. This is to teach us that a person who received Kedusha is guarded from falling all the way down, receiving extra Divine protection. It also can be said that the shape of the Kuf looks like a face with a long beard. As Chazal say, “Hadras panim zaken, The beauty of a face is the beard,” which points towards Kedusha. Numerically, Kuf is 100, which represents the peak of spiritual perfection that one can attain. The 10 of the letter Yud represents the spiritual perfection of Olam Habah which was created with it. The Kuf, however, represents haKadosh Barichu Himself! As the passuk says in Vayikra: “Kadosh Ani Hashem, I am God who is Holy!” Kedusha is the highest level of being, totally separate from everything. God describes Himself as Kadosh, lifted and exalted above all, even Olam Habah which is represented by the Yud/10. Kuf is 100 because it represents God, who is beyond Olam Habah. Ultimately, no one can ever see God because He is unfathomable, truly incomprehensible to the human mind.

Tehilim Perek 119: Letter SHIN Hello everybody, I’m Rabbi Shaya Sussman, covering the entire TANACH one perek at a time. Today’s Nach Daily will discuss the letter SHIN. The Shin represents the power of Shinuy, change in the creation and Shlita, control. Generally speaking, in order to change something you need to be in control of it. Shin is the force able to impact something by changing its form, bringing it to the desired outcome. The word Shinayim, teeth, comes from the Shin. When eating food, our teeth change its form so that the body can process and digest it. In fact, the tops of the letter Shin even look like teeth! On a deeper level, the Shin has the power to elevate. When we eat, the food becomes absorbed and digested into our bodies. It thus becomes a part of us, being elevated to the level of a human. As the expression goes, “You are what you eat!” Shin also applies to spirituality. A person’s desire to go from level to level, to reach higher and change for the better, comes from the word Shinuy, to change. The power of change and transition, like all traits, can be used for good or bad. Words like Shalom, peace, and Shelemos, perfection, as well as Sh’vira, breaking, Sheker, lies, and Satan, evil, begin with Shin. The first time that the Shin appears in the Torah is when it says “Es haShamayim v’es ha’aretz, Hashem created the heavens and earth.” The Gemarah in Chagiga 12a explains that Shamayim stands for Aish, fire, and Mayim, water. We know that part of the Shamayim is comprised of water, and that the atmosphere holds an electromagnetic field which allows lightning to be created. Both water and fire bring about change. In this context it can be said that Shamayim, sky, in some way rules over us by bringing about changes in the atmosphere. This all points towards the meaning of the letter Shin which controls, manipulates and changes. Numerically, the Shin is 300, representing the 3 strands of a cord that is not easily broken. The sequence of the letters Kuf, Reish, Shin signifies that first a person becomes Kadosh, holy, then he can become the Rosh, head, allowing him to lead Klal YiSrael. Alternatively, the Zohar explains, “Hakodosh Baruch, v’Oraysa V’Yisrael chad Hu, Hashem, the Torah and Am Yisrael are considered One.” Kuf: haKadosh Baruch-hu, Reish: oRaysa, the Torah, and Shin: YiSrael, the Jewish nation. These 3 aspects are unified through the Shin. The Shin is formed with 3 Vavs pointing upwards. The Vav is the os hachibur, letter of connection, pointing towards the Shin’s ability to tie together several aspects into a singular thread. Hashem, the Torah and Am Yisrael all become joined together through the 3 Vavs in the Shin. I hope that you enjoyed this class. It would be a Sin not to! It’s going to be Tough moving onto the Suff, finishing the last letter of the Aleph Beis. Thank you for listening, and have a wonderful day.

The letter Pei represents Pesicha, opening, Pesach, an entrance way, and superficial externalities. The mouth is called the Peh after the letter Pei because the mouth opens. Your mouth is what allows you to eat and nourish the body. Without it you wouldn’t be able to communicate your thoughts and desires. The Pei therefore represents the faculty of speech which comes through the mouth. The ability to bring your penimiyus to the chitzoniyus, inner self to the outer self,” is essentially self-actualization. The first time that the Pei is used in the Torah is when it says “v’ruach Elokim mirachePhes al Pnai hamayim,” and the spirit of God hovered over the face of the water. Pei here is used to describe the surface, the outer part, of the water. When contrasting the letter Pei to the letter Beis, we see that the Beis represents the penimiyus, internality, or inside of a house while the Pei represents the external, front of the house. Look at the letter Pei written as in a Sefer Torah, and stare at the negative space within the letter itself. The letter Beis will emerge! It is actually contained in the negative space of the Pei because the Pei represents externality while the Beis represents internality. To go a step deeper: We know that everything in this word can be used to serve Hashem. Anything physical, like a table or a car that is used for Mitzvos , becomes a vehicle to serve Him. As the whole point of chitzonyus is to reveal the penimyus, the whole point of all our physical possessions is to use them to serve God. The Pei points towards the letter Beis in the negative space to teach us not to get stuck on the physical trappings of this world, but to use them to reveal the Divine hidden behind them. The Pei is shaped like a mouth with a tooth hanging down from it because the Pei is synonymous with the Peh, mouth. The Pei is comprised of two letters, a Chuf and an upside down Yud. In previous classes we said that the Chuf represents bending in order to form something while Yud represents creating. The act of speaking is giving form to words by shaping and articulating sounds. This is represented by the Chuf-Yud combination which forms the Pei. Numerically, Pei equals 80, which represents gevurah, strength. In Tehilim 90:10 we’re told that the days of our lives are seventy years, “v’im b’gevoros shmonim shanah, and if strong, 80 years. Pirkei Avos says “ben shmonim le’gevurah, an 80 year old has strength.” Obviously this isn’t referring to physical strength, but the ability to live to conquer our Yetzer Harah. This requires guarding our mouths, represented by the Pei. There are two Pei’s, a regular Pei called Pei Kafufa, and a Pei Sofit, known as the Pei Pashuta. They ttell us that there’s a time for us to pay attention and not speak, as well as a time to open our mouths and speak what we know. The Pei Sofit, the Pei Pashuta, also represents the times of Mashiach. When Mashiach will reveal himself to the world, the Yetzer Hara will be completely nullified. This will cause people to “straighten out” and guard their mouths, only speaking words of chochma, wisdom. May we merit the times of the final redemption, when the world will be wide open to accepting God as the King of the cosmos. In the next episode of Nachdaily, we’ll be moving on to the righteous Tzaddik. Thank you for listening, and have a wonderful day.

Tehilim Perek 119: Letter Tzaddik Hello everybody, I’m Rabbi Shaya Sussman, covering the entire TANACH one perek at a time. Today’s we’ll discuss the letter TZADDIK. The letter Tzaddik represents Tzidkus, righteousness, Tzaddikim, and Tzida, trapping something. The Tzaddik is the ability to capture something and rule over it in a positive way. This can take the form of trapping animals and properly training them. Esav was “tzayid b’peav, he was able entrap someone with his words.” The root of the word Tzaddik refers to the righteous person who in a sense is able to trap the Yetzer Hara in order to rule over it. Tzaddi represents trapping and the Kuf at the end of it represents the Yezter Hara. This will hopefully be explained in the class pertaining to the letter Kuf. The first time that the letter Tzaddik appears in the beginning of a word in the Torah is during the creation of man. It says “b’Tzalmeinu, in Our image,” because the perfection of man lies in being alike to his Creator as much as possible. We can thus understand that the Tzaddik points towards shelaimus ha’adom, the perfection of man: to become a Tzaddik! Nowhere in the Torah are we commanded to kill our Yezter Hara, but we must use it for its intended purpose by ruling over it to serve Hashem. In the Shema we are told, “v’ahavta es Hashem Elohecha b’chol levav’cha, You should love Hashem with all your hearts.” Chazal explain that the plural use of “hearts” is to teach “b’shney yitzarecha, both the Yetzer Hatov v’Yetzer Hara, our good and evil inclinations.” There are two forms of this letter. A Tzaddik Kafufa, a regular bent Tzaddik, and a Tzaddik Peshuta AKA Tzaddik Sofit. Currently the Tzaddik is filled with humility, but when Mashiach comes the Tzaddik will become Peshuta, straightened out and stand upright, and all will see his true worth. The letter Tzaddik is formed with a Nun Kafufa, bent Nun, and a Yud. In a previous class we discussed that the Nun represents Ne’emanus, faithfulness, and aNava, humility. Those born naturally humble who didn’t really work on themselves for that trait are not called Tzaddikim. Only a person who works hard in avodos Hashem, serving Hashem and learning Torah is called a Tzaddik. Therefore the letter is also formed with a Yud, which represents attaching yourself to Hashem. Only after you attach yourself to God can you be called a Tzaddik. It also should be pointed out that the bent Nun in the formation of the Tzaddik is very bent over. A true Tzaddik is extremely humble in front of Hashem as it says regarding Moshe that he was “aNav mikol adom, humbler than all men.” Numerically, the Tzaddik is 90. Its lower counterpart letter is TES, which is 9. Tes represents the force of good that comes back to you. The connection here is obvious: the Tzaddik will receive good in the world to come. As the passuk in Yeshaya 3:10 says, “Imru l’Tzaddik ki Tov say to the Tzaddik he’s good.” Tzaddikim and goodness go hand in hand. A smart person contemplates this world and recognizes that all good will be received in the next world, represented by the relationship between the Tzaddik and its partner letter Tes. May we merit attaching ourselves to true Tzaddikim and ultimately become such ourselves through the power of the letter Tzaddik. Thank you for listening, and have a wonderful day.

Tehilim Perek 119: Letter NUN Hello everybody, I’m Rabbi Shaya Sussman, covering the entire TANACH one perek at a time. In today’s Nach Daily we’ll be discussing perek 119, letter NUN. The letter Nun represents Ne’emanut, loyalty, Namichut ruach, humility, Neshama, the soul, and Netzach, eternity. The Medrash Osyios D’Rebbe Akiva explains that the Neshama was created with the letter Nun. Without the soul the body would be as inanimate as the dirt on the ground, unable to stand erect or move in any way. The Medrash continues that this is represented by the two Nuns. The regular Nun is laying, while the Nun Sofit is standing. In the simple sense, the Medrash is speaking about the Neshama as it relates to its clothing, the body. However, in the deeper sense this means that when a person does mitzvos the Neshama is uplifted. When a person sins, however, the Neshama goes downwards as if it’s sleeping. A Neshama by nature is completely pure, trustworthy, loyal and filled with sublime humility before God, but our physical desires are constantly preventing it from revealing its true identity. This is all represented by the letter Nun, as the soul is constantly expressing its dedication to Hashem. The shape of a Nun is like a person sitting with their legs in front and the head tilted forward. This points towards the Neshama, which humbly subjugates itself to Hashem. It should be noted that when a person is constantly like the Nun Kafuf, humbly sitting in front of God, in the end he will be like the Nun Pashuta, straightened out for Olam Habah. Numerically, the Nun is 50. Fifty represents the “Chamishim Sha’arei Bina, 50 Gates of Understanding, the 50 gates of Kedusha, Holiness, and the 50 days to receiving the Torah. The only way to reach the highest level is though aNava, humility. Therefore, it was specifically Moshe who attained the fiftieth level which allowed him to receive the Torah because he was aNav mikol adom, the most humble man on earth. This is all represented by the letter Nun which is numerically fifty and corresponds to humility, loyalty, and subjugation. The Nun is also a feminine letter as Nekieva, which starts with a Nun, means female. Women have an easier time humbling themselves to Hashem because they are more naturally connected, dedicated and loyal. This is why women make the bracha in the morning “asani kirtzono, Hashem created me according to His will. Generally speaking, women feel more connected to Hashem because they were created in tandem with God’s Ratzon, will. Nun is also the letter for Nefila, falling. In life we tend to fall, but we always trust that “yerida tachlis ha’aliya, every descent is really an ascent.” Every fall is really Hashem drawing you closer to Him. In this context it can be understood that every Nefilah, falling is really for the good. It’s specifically from that place of Nefilah that you can accrue credit for Netzach, eternity. May we merit constantly humbling ourselves in front of Hashem, remembering that we are Nothing, which starts with a Nun, in the eyes of the Creator. Stay tuned for our next episode in which we’ll be moving on to the letter Samech. Thank you for listening, and have a wonderful day.

Ches represents the soul of life, Chayim and Chein, going beyond nature and beChira, free choice. The first time that Ches is seen in the Torah is during creation. “v’Choshech al p’ney tahom,’ and darkness was on the face of the deep.” Because the world was created with Choshech, darkness, it’s very difficult to see Hashem. We need to use our free choice to see through or beyond the darkness. The power of free choice comes from the Ches contained in the word Choshech. “Olam hazeh domeh l’layla, this word is compared to the night time.” The word for darkness also contains the letter Ches, which is the ability to transcend the darkness! Because Ches represents many strong spiritual movements essential for life, it will be found beginning words that deal with strong activity and movement: Cham, heat; Chituch, cutting; Charitsut, diligence; Chozek, strength; Chod and Chanit, both meaning spear; Chetz, arrow, and Cherev, sword. The letter also represents strong movement. Many strong human emotions also begin with Ches: Chas, compassion; Chessed, kindness; Chemlah, desire; Chanina, grace; Chibah, affection. It can be said that these feeling come from the heat and movement of the soul. Ches therefore also represents the neshama, soul, found within physicality. It should be noted that there are many other feelings which contain a Ches in them, but don’t begin with it: simCha, happiness; s’Chok, laughter, and anaCha, sighing or groaning. Ches is the spiritual force for movement, and feelings are naturally always changing and moving. This is a bit difficult to explain without a picture, but the letter Ches looks like two legs supporting the rest of a body. The reason for this is that people who are Chai, alive, can usually stand by themselves, in contrast to the dead. The letter is actually formed with two Zayins connecting each other. We explained previously that the Zayin, shaped like a hammer, represents kli Zayin, weapons of war. The double Zayin in the Ches represents the two wars, physical and spiritual, that we battle throughout our lives. Our physical desires need to conquered and subjugated, and our minds need to be tilted towards truth and spirituality. Again, we see how the letter Ches points towards using our free choice to attain true Chaim, life. Chet means sin. In modern Hebrew we say that an archer is maCh’tie, misses the target. One who sins is missing the point of this world. On the other hand, Chet can mean Chituy, disinfection. We can use the power of free choice contained in the letter Ches to disinfect ourselves and become tahor, pure and clean. Numerically, Ches is 8. 7 represents the spirituality found in nature, while 8 represents that which is found beyond nature and the limitations of this world. Many times, in the Torah, we find 8 pointing towards this. For example: the 8th day for a bris, 8 tzitzis, Shemini Ateres, the 8th day after 7 days of Sukkos, and eight days of Chanukah. They all represent the concepts of going beyond this world and are connected to the Ches, which points towards free choice and the spiritual dimension beyond this world. The word chein, charm, is spelled Ches nun. Rebbe Nachman explains that it stands for Chochmas Nistar, hidden mystical wisdom. When we say that someone has chein, it means an inner Godly charm, spiritually infused with God’s grace.

Asymptotic-preserving Schemes for the Boltzmann Equation and Related Problems

We propose a general framework to design asymptotic preserving schemes for the Boltzmann kinetic kinetic and related equations. Numerically solving these equations are challenging due to the nonlinear stiff collision (source) terms induced by small mean free or relaxation time. We propose to penalize the nonlinear collision term by a BGK-type relaxation term, which can be solved explicitly even if discretized implicitly in time. Moreover, the BGK-type relaxation operator helps to drive the density distribution toward the local Maxwellian, thus natually imposes an asymptotic-preserving scheme in the Euler limit. The scheme so designed does not need any nonlinear iterative solver or the use of Wild Sum. It is uniformly stable in terms of the (possibly small) Knudsen number, and can capture the macroscopic fluid dynamic (Euler) limit even if the small scale determined by the Knudsen number is not numerically resolved. It is also consistent to the compressible Navier-Stokes equations if the viscosity and heat conductivity are numerically resolved. The method is applicable to many other related problems, such as hyperbolic systems with stiff relaxation, and high order parabilic equations.

Structured additive regression for multicategorical space-time data: A mixed model approach

In many practical situations, simple regression models suffer from the fact that the dependence of responses on covariates can not be sufficiently described by a purely parametric predictor. For example effects of continuous covariates may be nonlinear or complex interactions between covariates may be present. A specific problem of space-time data is that observations are in general spatially and/or temporally correlated. Moreover, unobserved heterogeneity between individuals or units may be present. While, in recent years, there has been a lot of work in this area dealing with univariate response models, only limited attention has been given to models for multicategorical space-time data. We propose a general class of structured additive regression models (STAR) for multicategorical responses, allowing for a flexible semiparametric predictor. This class includes models for multinomial responses with unordered categories as well as models for ordinal responses. Non-linear effects of continuous covariates, time trends and interactions between continuous covariates are modelled through Bayesian versions of penalized splines and flexible seasonal components. Spatial effects can be estimated based on Markov random fields, stationary Gaussian random fields or two-dimensional penalized splines. We present our approach from a Bayesian perspective, allowing to treat all functions and effects within a unified general framework by assigning appropriate priors with different forms and degrees of smoothness. Inference is performed on the basis of a multicategorical linear mixed model representation. This can be viewed as posterior mode estimation and is closely related to penalized likelihood estimation in a frequentist setting. Variance components, corresponding to inverse smoothing parameters, are then estimated by using restricted maximum likelihood. Numerically efficient algorithms allow computations even for fairly large data sets. As a typical example we present results on an analysis of data from a forest health survey.
