Patrick Vanraes is a postdoctoral researcher at the University of Antwerp whose research into liquid plasmas has led him to believe that we have radically, completely, totally misunderstood what it means for something to be “plasma.” All presentations on the subject begin with a rote recitation of the fact that plasma is a fourth state of matter - solid, liquid, gas, then plasma. But Patrick makes the point that this is an incomprehensible perspective, because the phase change between solid - liquid - gas is one of motion. Each phase has more degrees of freedom than the previous one, and so reveals different macroscopic qualities of the substance. The transition to plasma is far stranger. Some component of it does include a greater range of motion, as the electron shells of the atoms bloom away from their ionic cores. But far more important is the structural, chemical changes that accompany plasma, which is exactly what leads Patrick to the conclusion that perhaps plasma isn't some strange exotic kind of matter - it's some latent capacity of matter that's far more ordinaryMAKE HISTORY WITH US THIS SUMMER:https://demystifysci.com/demysticon-2025PATREON https://www.patreon.com/c/demystifysciPARADIGM DRIFThttps://demystifysci.com/paradigm-drift-show00:00 Go!00:05:13 Cosmos and Plasma Complexity00:11:41 Defining Plasma Beyond Ionized Gas00:17:07 Applications and Implications of Plasma Understanding00:21:52 Plasma in Laboratory and Experimentation00:24:27 Plasma Formation in Gas vs. Liquid00:26:31 Plasma Research Fields00:31:15 Definition and Nature of Plasmas00:39:01 Phase Transitions and Plasma States00:42:11 Ionization and Conductivity in Metals00:48:31 Atomic Structure and Misconceptions00:49:54 Realism in Scientific Models00:52:30 Complexities in Education and Models00:55:38 Redefining Plasma and Conductivity01:00:07 Characteristics of Plasma01:11:05 Plasma Waves and Oscillations01:15:36 Particle Misconceptions01:20:59 Material Representation in Physics01:23:30 Stars and Material Conceptions01:29:38 Quasi-Particles and Limitations01:31:30 Beyond Models: Reality vs. Philosophy01:36:13 Phonon Theory of Liquids01:39:12 Relationship Between Phonons and Specific Heat01:40:25 The Temperature Dependency of Specific Heat01:43:35 Conceptualizing Quasi-Particles and Reality01:50:16 Exploring Underlying Structures in Physics01:57:05 The Philosophical Underpinning of Scientific Theories02:03:34 Plasma Physics, Redefined02:08:16 The Role of Skepticism and Prediction in Science02:12:26 Building Scientific Community and Collaboration02:16:50 Modeling a New Scientific Approach02:17:28 Upcoming Presentations on Plasma Models #plasmaphysics, #astrophysics, #experimentalphysics, #electricuniverse, #theoreticalphysics, philosophypodcast, #sciencepodcast, #longformpodcast ABOUS US: Anastasia completed her PhD studying bioelectricity at Columbia University.

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks… Kelly: Hi Dr. Cabral! It's Kelly, an IHP L2 & lover of ALL things health, wealth & wellness. I would love to hear your POV, evidence based of course, on ( maybe don't say the product name - totally up to your digression) Enagic K8 water ionization system. Which creates more hydrogen rich water & to my understanding is more bioavailable to the body, acting almost like an adaptogenic, being a small enough molecule to penetrate the cell walls & even pass the blood brain barrier. I am always curious & have been incorporating with my clients wellness plans. As water, like food, movement and all the layers in the ‘DESTRESS' protocol are important. I do however want to practice with integrity & I am chasing your wisdom . Would you consider it for a product review in the future? If so reach out Holly: Hi Dr. C! I have Alopecia Areata (40yr old women) and have tried all your hair loss protocols (including massively reducing stressors) alas nothing is working! I've resisted the steroid creams the doctor prescribed so far but running out of options. My question is about your thoughts on micro needling? And also thoughts on hyaluronic acid serum? (Or other recommendations). Thanks Holly Oliver: Hi Stephen, Are there any benefits or negatives to listening to podcasts/audiobooks at a fast speed? I listen to most podcasts at 2x speed which is great to consume lots of info quickly but my mum thinks its bad for you so wondered if there is any effect on the brain? Tessi: Hi Dr! I have addisons disease and noticed my blood work shows really high levels of hemocrit and hemoglobin on my blood work. Is this normally associated with having an adrenal issue or could it be something more? Any ways to lower it naturally? Josh: Hi Dr. Cabral - thank you for all you do to educate us. I take a number of vitamins & minerals daily, many of which are taken at the same time. I'm curious if there are any vitamins/minerals that should not be taken together and if there are any that are best taken on an empty stomach. I understand fat soluble should be taken with healthy fats, but aside from that, I'm unaware of any considerations. Thank you!

The Space, Astronomy & Science Podcast.SpaceTime Series 27 Episode 38*Witnessing the Final Stages of Planetary FormationFor the first time, astronomers have captured the end of the planetary formation process, observing the dispersal of gas from a young star's circumstellar disk. The James Webb Space Telescope has provided unprecedented images of the Tchar star system, where a vast gap in its disk suggests we're witnessing the final act in its planetary evolution. The study sheds light on the fate of gas giants and terrestrial planets, revealing the delicate dance of creation that shapes nascent solar systems.*The Devil's Comet: A Green Spectacle in the SkyComet 12P/Pons-Brooks, with its distinctive green hue and horned appearance, is making its first visit to the inner solar system in over 70 years. This Mount Everest-sized icy wanderer could grace our skies with its naked-eye visibility as it reaches perihelion this April. Nicknamed the 'Devil's Comet', its cryovolcanic nature promises a celestial show that won't return until 2095.*The Dust that Doomed DinosaursA new study proposes that fine dust particles from the Chicxulub asteroid impact contributed significantly to the mass extinction event that ended the reign of the non-avian dinosaurs. By blocking photosynthesis and plunging the Earth into a cold, dark winter, this fine dust may have been the final nail in the coffin for many species, reshaping life on our planet forever.For more SpaceTime and to support the show, visit our website at https://spacetimewithstuartgary.com where you can access our universal listen link, find show notes, and learn how to become a patron.Listen to SpaceTime on your favorite podcast app with our universal listen link: https://spacetimewithstuartgary.com/listen and access show links via https://linktr.ee/biteszHQSupport the show: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/supportFor more space and astronomy podcasts, visit our HQ at https://bitesz.com

Stochasticity of Cosmic Rays from Supernova Remnants and the Ionization Rates in Molecular Clouds by Vo Hong Minh Phan et al. on Thursday 22 September Cosmic rays are the only agent able to penetrate into the interior of dense molecular clouds. Depositing (part of) their energy through ionisation, cosmic rays play an essential role in determining the physical and chemical evolution of star-forming regions. To a first approximation their effect can be quantified by the cosmic-ray induced ionization rate. Interestingly, theoretical estimates of the ionization rate assuming the cosmic-ray spectra observed in the local interstellar medium result in an ionization rate that is one to two orders of magnitude below the values inferred from observations. However, due to the discrete nature of sources, the local spectra of MeV cosmic rays are in general not representative for the spectra elsewhere in the Galaxy. Such stochasticity effects have the potential of reconciling modelled ionization rates with measured ones. Here, we model the distribution of low-energy cosmic-ray spectra expected from a statistical population of supernova remnants in the Milky Way. The corresponding distribution for the ionization rate is derived and confronted with data. We find that the stochastic uncertainty helps with explaining the surprisingly high ionization rates observed in many molecular clouds. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.10581v1
Low-ionization structures in planetary nebulae -- II Densities, temperatures, abundances and excitation of 6 PNe by M. Belén Mari et al. on Thursday 22 September Here we present the spatially resolved study of six Galactic planetary nebulae (PNe), namely IC 4593, Hen 2-186, Hen 2-429, NGC 3918, NGC 6543 and NGC 6905, from intermediate-resolution spectra of the 2.5 m Isaac Newton Telescope and the 1.54 m Danish telescope. The physical conditions (electron densities, N$_{e}$, and temperatures, T$_{e}$), chemical compositions and dominant excitation mechanisms for the different regions of these objects are derived, in an attempt to go deeper on the knowledge of the low-ionization structures (LISs) hosted by these PNe. We reinforce the previous conclusions that LISs are characterized by lower (or at most equal) N$_{e}$ than their associated rims and shells. As for the T$_{e}$, we point out a textit{possible} different trend between the N and O diagnostics. T$_e$[NII] does not show significant variations throughout the nebular components, whereas T$_e$[OIII] appears to be slightly higher for LISs. The much larger uncertainties associated with the T$_e$[OIII] of LISs do not allow robust conclusions. Moreover, the chemical abundances show no variation from one to another PN components, not even contrasting LISs with rims and shells, as also found in a number of other works. By discussing the ionization photon flux due to shocks and stellar radiation, we explore the possible mechanisms responsible for the excitation of LISs. We argue that the presence of shocks in LISs is not negligible, although there is a strong dependence on the orientation of the host PNe and LISs. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.10988v1
Magnetically regulated collapse in the B335 protostar? II Observational constraints on gas ionization and magnetic field coupling by Victoria Cabedo et al. on Wednesday 21 September Non-ideal magnetohydrodynamic effects that rule the coupling of the magnetic field to the circumstellar gas during the low-mass star formation process depend heavily on the local physical conditions, such as the ionization fraction of the gas. The purpose of this work is to observationally characterize the level of ionization of the circumstellar gas at small envelope radii and investigate its relation to the efficiency of the coupling between the star-forming gas and the magnetic field in the Class 0 protostar B335. We have obtained molecular line emission maps of B335 with ALMA, which we use to measure the deuteration fraction of the gas, its ionization fraction, and the cosmic-ray ionization rate, at envelope radii $lesssim$1000 au. We find large fractions of ionized gas, $chi_{e} simeq 1-8 times 10^{-6}$. Our observations also reveal an enhanced ionization that increases at small envelope radii, reaching values up to $zeta_{CR} simeq 10^{-14}$~s$^{-1}$ at a few hundred au from the central protostellar object. We show that this extreme ionization rate can be attributed to the presence of cosmic rays accelerated close to the protostar. We report the first resolved map of the cosmic-ray ionization rate at scales $lesssim 1000$~au in a solar-type Class 0 protostar, finding remarkably high values. Our observations suggest that local acceleration of cosmic rays, and not the penetration of interstellar Galactic cosmic rays, may be responsible for the gas ionization in the inner envelope, potentially down to disk forming scales. If confirmed, our findings imply that protostellar disk properties may also be determined by local processes setting the coupling between the gas and the magnetic field, and not only by the amount of angular momentum available at large envelope scales and the magnetic field strength in protostellar cores. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2204.10043v2

Contribution of polycyclic aromatic hydrocarbon ionization to neutral gas heating in galaxies: model versus observations by O. Berné et al. on Tuesday 20 September [Abridged] The ionization of polycyclic aromatic hydrocarbons (PAHs), by ultraviolet (UV) photons from massive stars is expected to account for a large fraction of the heating of neutral gas in galaxies. Evaluation of this proposal, however, has been limited by our ability to directly compare observational diagnostics to the results of a molecular model describing PAH ionization. The objective of this article is to take advantage of the most recent values of molecular parameters derived from laboratory experiments and quantum chemical calculations on PAHs and provide a detailed comparison between modeled values and observational diagnostics for the PAH charge state and the heating efficiency for PAHs. Despite the use of a simple analytical model, we obtain a good agreement between model results and observational diagnostics over a wide range of radiation fields and physical conditions, in environments such as star-forming regions, galaxies, and protoplanetary disks. In addition, we found that the modeled photoelectric heating rates by PAHs are close to the observed cooling rates given by the gas emission. These results show that PAH ionization is the main source of neutral gas heating in these environments. The results of our photoelectric heating model by PAHs can thus be used to assess the contribution of UV radiative heating in galaxies (vs shocks, for instance). We provide the empirical formulas fitted to the model results, and the full python code itself, to calculate the heating rates and heating efficiencies for PAHs. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.08762v2
Cosmic-ray ionization rate in protoplanetary disks with sheared magnetic fields by Yuri I. Fujii et al. on Thursday 15 September We investigate the effects of magnetic field configurations on the ionization rate by cosmic rays in protoplanetary disks. First, we consider cosmic-ray propagation from the interstellar medium (ISM) to the protoplanetary disks and showed that the cosmic-ray density around the disk should be 2 times lower than the ISM value. Then, we compute the attenuation of cosmic rays in protoplanetary disks. The magnetic fields in the disk are stretched to the azimuthal directions, and cosmic rays need to detour while propagating to the midplane. Our results show that the detouring effectively enhances the column density by about two orders of magnitudes. We employ a typical ionization rate by cosmic rays in diffuse ISM, which is considered too high to be consistent with observations of protoplanetary disks, and find that the cosmic rays are significantly shielded at the midplane. In the case of the disk around IM Lup, the midplane ionization rate is very low for $rlesssim,100$ au, while the value is as large as a diffuse ISM in the outer radii. Our results are consistent with the recent ALMA observation that indicates the radial gradient in the cosmic-ray ionization rate. The high ionization rate in the outer radii of disks may activate the magnetorotational instability that was thought to be suppressed due to ambipolar diffusion. These results will have a strong influence on the dynamical and chemical evolutions of protoplanetary disks. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.02503v2

There's so much we don't know, or take for granted, about the way life really works on this planet. There's the biosphere, which includes the soft electricity of the Terran Field. I coined the words “Terran Field” to describe the background organic electrical nature of the interplay between life on the planet's surface and its oceans, and the upper atmospheric structures that feed subtle electrical energies between the ionosphere and ground. Lightning for example - without it we wouldn't have life, or the components that create and sustain life. Over the past half century some members of the military-scientific community have discovered some of what Tesla understood, and weaponized it for their own purposes. As a result, much of what we witness or experience daily now is degrading our life experience, or the ability of the planet to sustain itself. Geoengineering, smartphones, smart meters, 5G, nano particulates, graphene oxide, mind control…nefarious activity that victimizes the unawares. We must become aware to change course…we need to understand to respond.

M., Wittwer, C., Jork, N., Gu, C., Shears, S. B., Schaaf, G., Kammerer, B., Fiedler, D., Saiardi, A., Jessen, H. J. Abstract: The analysis of myo-inositol phosphates (InsPs) and myo-inositol pyrophosphates (PP-InsPs) is a daunting challenge due to the large number of possible isomers, the absence of a chromophore, the high charge density, the low abundance, and the instability of the esters and anhydrides. Given their importance in biology, an analytical approach to follow and understand this complex signaling hub is highly desirable. Here, capillary electrophoresis (CE) coupled to electrospray ionization mass spectrometry (ESI-MS) is implemented to analyze complex mixtures of InsPs and PP-InsPs with high sensitivity. Stable isotope labeled (SIL) internal standards allow for matrix-independent quantitative assignment. The method is validated in wild-type and knockout mammalian cell lines and in model organisms. SIL-CE-ESI-MS enables for the first time the accurate monitoring of InsPs and PP-InsPs arising from compartmentalized cellular synthesis pathways, by feeding cells with either [13C6]-myo-inositol or [13C6]-D-glucose. In doing so, we uncover that there must be unknown inositol synthesis pathways in mammals, highlighting the unique potential of this method to dissect inositol phosphate metabolism and signalling.

Welcome The BG Podcast! Conversations at the intersection of business, community, and public policy, from the Austin metro and around Texas. Today we speak with Cree Crawford, Founder and President of Ionization Labs. He and Bingham Group CEO A.J. discuss the firm's Cannabinoid Identification (Cann-ID), Cloud-Based, QA/QC Hemp & Marijuana potency testing solution. In June, the 86th Texas Legislature passed House Bill 1325, which legalized the production of hemp with a THC concentration of less than 0.3%. The latter legislation follows the hemp definition laid out in the 2018 Farm Bill. Following this passage, state entities, local law enforcement and the legal system struggled with enforcing and persecuting marijuana usage, which is still and illegal controlled substance in accordance with state and federal law. Hemp and marijuana are both derived from cannabis sativa, but hemp must have a THC concentration of less than 0.3%. To determine if an individual is legally using hemp or illegally using marijuana, law enforcement would need testing to prove the THC concentration is above the legal limit, which is not currently available in many law enforcement testing centers. Ionization Labs Cann-ID solution provides one potential solution. Originally recorded on August 19, 2019. ABOUT CREE CRAWFORD Cree is president at Ionization Labs. Ionization Labs provides pre-measured, pre-filled, pre-packaged kits for Cann-ID. Their solution processes 14 of the most prevalent cannabinoids to provide consistent testing results.

Yet another faddish health product is alkaline water, which contains less acid than tap water. The theory is that there are health benefits to lower acid levels in the body. But it's not that simple. Our bodies need minimum levels of acid to function properly. If those levels are unbalanced, your health will suffer. So how do you determine the right balances, and how do you make sure you have them?
Jess Wisse (JW): What's behind the science and inventions that impact our daily lives? Pacific Northwest National Laboratory’s Pods of Science are the stories of what happens before the breakthrough. Before a technology becomes a house-hold name, before the life-saving drug his pharmacy shelves, before the paper's published - see what happens when great minds meet great challenges. Music Welcome. I’m your host, Jess Wisse. On today’s episode we’ll talking about new technology that may give dogs a run for their money. Wondering what we’re talking about? Stay tuned to learn more. Music JW: Floppy-eared sniffer dogs made the news earlier this year as the latest change to security procedures in airports. But in the not-too-distant future, they could be replaced. The replacement is a technology that doesn’t require a scratch behind the ear and a treat to its job. Meet the man behind the tech: Robert Ewing. Robert Ewing (RE): I like discovering things. I like solving puzzles. I like doing things that I don't think are possible, or challenging. And learning. JW: Robert Ewing is a scientist at PNNL. And he’s made a discovery that could potentially save lives. RE: I'm Robert Ewing. I'm a research chemist at the Pacific Northwest National Lab. I've been here for about 13 years. I've studied various analytical techniques for detecting trace of stances explosives and drugs, or some of those compounds. Ionization chemistry as a part of that. The instrumentation that goes along with that. Those are some of the things that I do for fun. JW: So, what did Robert discover? He and his team at PNNL developed a technology that’s ultrasensitive. It detects explosive vapors, deadly chemicals, and drugs like methamphetamine and fentanyl with unparalleled accuracy. And it works in seconds. RE: The technology really stems from using the detector of a mass spectrometer. And that's a way to look at different molecules, to understand what mass is there. And from that you can sort of determine the analyte. Here you're looking at what we did, or one of the challenges, was is the ionization. So, for the mass spec to see a molecule you've got to put a charge on there so it can manipulate that charge, create an electric field, and separate it. And so the ionization process is a way of getting that charge, that electrical charge, onto an individual molecule. And that's really where I've spent a lot of my time—understanding the chemistry around how that ionization process works and how to improve upon it. With the commercial mass specs that are out there that are pretty sensitive (parts per billion range and stuff) work pretty well. What we did is, we discovered that if you increase the amount of time that the ionization process can occur you can increase the sensitivity. And so the mass spec has a pinhole bringing the ions in from outside. What we do is, we took the ionization source and moved that away from the mass spec, and instead of having a few milliseconds of reaction time we give it two or three seconds and that gave us several orders of magnitude increase in sensitivity. JW: This technology could be a game-changer for transportation hubs, mail facilities, and other safety and security screening applications, like the ones you see in airports. Thanks to Robert’s tireless efforts, the system can detect a whole slew of things. Including explosive vapors, like TNT, toxic chemicals similar to nerve agents, and even illicit drugs, like fentanyl, methamphetamine, and cocaine. The most surprising part? Robert thought this was a problem that was un-solvable. But he kept mulling on the idea, and that got him to think about none other than man’s best friend. RE: Probably one of the driving force—the ah-hah moments—I always thought that explosive vapor was a challenge that we probably wouldn't overcome. And yet, dogs go out and sniff explosives all the time. Well, I've always wondered what dogs really smell? You know, are they smelling the explosive? Are they smelling the other things that surround that are that are higher vapor pressure, more volatile? And I remember I went to a conference on explosives detection and they had a guy who had a detector dog and showed the detection of RDX. But he talked about his process of how he purified it, cleaned it, then trained his dog and showed it. And I watched it, you know, I watched the video. That dog has really seen. And I was like, “why can't we do that?” And so it was really about a month later when I was in the lab and said, “well, okay I got all the right tools.” I put it all together and on a Friday afternoon, I made it work. I mean so at some point it just happened. JW: So how did Robert train this technology to sniff out specific vapors? The answer: Selective ionization chemistry. RE: We talked about selective ionization chemistry. When you're detecting vapor at low parts per trillion parts per quadrillion levels there's a lot other things in the room. So we try to find selective ionization, so it's kind of like finding a needle in a haystack. You know how you do that? You use a magnet, right? The magnet is selective to the needle. It finds the metal and it ignores the straw. This is the same kind of thing. And that's where we spend a lot of our time is in that chemistry. Pick the right reactant ions, the ions that you want to has will analyze your analyte, and with that will analyze the materials we are looking for, and be kind of be invisible to the other species. So some examples there, you asked what chemicals we look at. You know explosives was one example. You want to see explosives, but maybe you don't want to see the various hydrocarbons and diesel fuel or gasoline or perfumes or colognes—things like that. And so that's the selectivity part. JW: But for the longest time, detection of certain explosive vapors, like TNT, wasn’t possible. The instrumentation just wasn’t sensitive enough. Typical instrumentation can see chemical levels in the parts per million and billion range. But many of the explosives out there in the world have very low vapor pressures—they’re more like in the low parts per trillion or below. RE: So, an air you've got molecules and stuff floating around. They're always bumping into each other. I mean there's like 10 to the 11th collisions per second for a molecule, and air that's occurring. And so to bring those two together, you've got lots of lots of collisions that are probably going to occur. And so more time just gives you a higher probability that interactions going to happen. JW: So now that we can detect things like explosives, what’s the future look like? RE: So, one of the aspects of this this equipment. By being able to see vapor detection, that allows you to have non-contact detection. So, when you go through an airport nowadays, they usually swipe your bag and run it through an instrument looking for explosive residue. This ability to see vapor kind of helps remove that contact, so it's a little less invasive. So, you can do maybe baggage screening or cargo screening, or you know even people when you walk through the imagers there to have a look for vapor at the same time. And so really, it's taking the next step of non-contact. Hopefully increasing screening speed, getting people through the airports quicker, and also maybe a little more thorough in your searches. It's sort of that vision what we hope to do is be able to take this instrument and work with a smaller mass spec so then you can you get it in a footprint that's similar to stuff that's in the airport. Or you can integrate it to x-ray machines, or so forth. So, that's kind of what our hope is—to you know, take this to the next level. Get it into a smaller more portable size, and be able to test it and evaluate it, and see what other challenges need to be fixed. JW: We asked Robert how it feels to know that he’s responsible for a technology that could potentially save lives. And he said, “it’s pretty cool.” RE: It's challenging too because what we do doesn't happen overnight. I mean there every now then you have really good days and there's sometimes months where you struggle to get make things. So, it's a mix of, it takes a lot of determination to find those good breakthroughs. JW: So, while it may not be in your local airport yet, PNNL’s vapor detection technology has a bright future. And that’s exciting. [Music] JW: Thanks for listening to Pods of Science. Want to learn more? Follow us on social media at PNNLab. We're on Twitter, Instagram, Facebook, and LinkedIn.

Inborn errors of metabolism are rare diseases in which a single gene defect causes a clinically significant block in a metabolic pathway resulting either in an accumulation of substrate behind the block or a lack or deficiency of the product. Profiling metabolites in the pathway could allow for accurate and timely identification of patients who have these diseases and help physicians to devise effective treatment. Congenital disorders of glycosylation represent one of the largest groups of such metabolic disorders. In May 2019, Clinical Chemistry published a study on the development and validation of a plasma protein N-glycan assay using a flow injection-electrospray ionization-quadrupole time-of-flight mass spectrometry.

Surgery is a common form of treatment in patients with solid tumors. Depending on the cancer, surgery may be used to remove cancer that is contained within a specific area, to debulk a tumor, or to ease symptoms caused by a tumor. In each case, it is critical to distinguish cancerous from noncancerous tissue during the operation. Today, pathologists perform rapid microscopic investigations of biopsied tissue and make the diagnosis. In the future, this may be conducted using mass spectrometry based measurements. Ambient ionization mass spectrometry methods make localized molecular level chemical analysis of tissue samples possible at atmospheric pressure and without prior sample purification and pre-treatment. Over the past decades, scientific advances have extended the role of these methods from the research laboratory to the operating room. The April 2018 issue of Clinical Chemistry includes a commentary on the different technologies and their potential in cancer diagnosis.

Today’s guests are the team at Elite Level Performance in Colliersville, TN, owner John Nelson and trainer/natural health practitioner, Mandy Macri. I originally met John at the first Track/Football Consortium in Lombard, Ill, and have since had some great conversations with him on holistic health, Be Activated/RPR, Jay Schroeder training ideas, and more. John Nelson brings over a decade of experience and expertise to all clients. He has a Masters Degree in Health & Sport Science, and is also a National Academy of Sports Medicine Certified Corrective Exercise Specialist & Personal Trainer. Mandy Macri joined Elite Level Performance in 2012 after 20 years in the health & fitness industry. Mandy has a degree in Computer Engineering from Georgia Tech, and is a National Academy of Sports Medicine Certified Personal Trainer and Corrective Exercise Specialist. Mandy has her Natural Health Practitioner Certification from Trinity School of Natural Health, and is currently completing her dissertation to receive her Doctor of Naturopathic Medicine degree from Trinity School and Natural Health. One of the most interesting things that piqued my interest in what John, and Mandy were doing at ELP was John talking about the relationship of muscle testing to the holistic (nutritional, psychological) aspects of the athlete in getting longer lasting results of muscle activation and strength in things like hip extension, flexion, etc. Much of the muscle testing and related corrective systems we see today will deliver fairly temporary changes. The modalities and total integrative approach at ELP really sets what John and Mandy are doing apart, and as we learn more about the connections of the human body, we can become more effective coaches and athletes. Today’s episode is all about the relationship between nutrition to athletic function, with many facets of both also discussed individually. Today’s episode is brought to you by SimpliFaster, supplier of high-end athletic development tools, such as the Freelap timing system, kBox, Sprint 1080, and more. Key Points: John and Mandy’s backgrounds, and the formation of Elite Level Performance Physical, neurological and nutritional assessments of athletes at ELP Critical physical assessments for athletes in the ankle and hip A summary of the RBTI (Reams Biological Theory of Ionization) in performance assessment Common physical deficiencies in athletes John and Mandi work with Aspects of digestion in physical performance John’s training philosophy Quotes “A commonality I tend to find is basically an overload of the system in too much sugar, too many electrolytes, and an inability to process out those proteins” “If your body cannot send and receive information the right way, it is going to start to compensate” “Our kids know that Gatorade is not the best choice” “PH is how fast things are moving through your digestive tract” “I think just getting the physical component is a cop-out when you are not addressing the true origin of the (muscle weakness) situation” “Protein is extremely important, but is also the hardest thing for your body to break down.” “Just because you chew, swallow and something comes out the other end doesn’t mean all was good, and with protein especially” “A simple enzyme deficiency might be the only thing standing in your way between making the gains you want and staying where you are” “Most of the standard American diet is going to push you too acidic, or too fast, pushing things through the system too fast for good absorption.” “If a person is chronically not activated in their psoas or glutes, then there is something internally going wrong” Show Notes A simple book recommended to be post-recording by Mandy was “Kick Your Fat in the Nuts”, which goes into aspects of digestion that was discussed in the show. It is a very interesting and eye opening read.

A driving force in the development of point-of-care diagnostics is to conveniently provide information without delay so that healthcare decisions can be made while the patient is on-site. Most point-of-care devices are based on immunochemical, electrochemicalor colorimetric techniques that can be miniaturized and made portable.

Non-solar composition of the donor star in ultra-compact X-ray binaries (UCXBs) may have a pronounced effect on the fluorescent lines appearing in their spectra due to reprocessing of primary radiation by the accretion disc and the white dwarf surface. We show that the most dramatic and easily observable consequence of the anomalous C/O abundance is the significant, by more than an order of magnitude, attenuation of the Kα line of iron. It is caused by screening of the presence of iron by oxygen - in the C/O-dominated material the main interaction process for an E ~ 7 keV photon is absorption by oxygen rather than by iron, contrary to the solar composition case. Ionization of oxygen at high mass accretion rates adds a luminosity dependence to this behaviour - the iron line is significantly suppressed only at low luminosity, log (LX) < 37-37.5, and should recover its nominal strength at higher luminosity. The increase of the equivalent width of the Kα lines of carbon and oxygen, on the other hand, saturates at rather moderate values. Screening by He is less important, due to its low ionization threshold and because in the accretion disc it is mostly ionized. Consequently, in the case of the He-rich donor, the iron line strength remains close to its nominal value, determined by the iron abundance in the accretion disc. This opens the possibility of constraining the nature of donor stars in UCXBs by means of X-ray spectroscopy with moderate energy resolution.
We present here an application of the recently developed hybrid coupled channels approach to study photo-ionization of noble gas atoms: Neon and Argon. We first compute multi-photon ionization rates and cross-sections for these inert gas atoms with our approach and compare them with reliable data available from R-matrix Floquet theory. The good agreement between coupled channels and R-matrix Floquet theory show that our method treats multi-electron systems on par with the well established R-matrix theory. We then apply the time dependent surface flux (tSURFF) method with our approach to compute total and angle resolved photo-electron spectra from Argon with linearly and circularly polarized 12 nm wavelength laser fields, a typical wavelength available from Free Electron Lasers (FELs)

Carolyn J. Cassady discusses how Matrix-assisted Laser Desorption Ionization (MALDI) helped to revolutionize mass spectrometry and ultimately simplify it through specific polymers used in the reaction. She goes on to discuss MALDI and mass spectrometry work based on the nanoparticles that make the necessary reactions happen.
The ionization and fragmentation dynamics of iodine molecules (I-2) are traced using very intense (similar to 10(14) W cm(-2)) ultra-short (similar to 60 fs) light pulses with 87 eV photons of the Free-electron LASer at Hamburg (FLASH) in combination with a synchronized femtosecond optical laser. Within a pump-probe scheme the IR pulse initiates a molecular fragmentation and then, after an adjustable time delay, the system is exposed to an intense FEL pulse. This way we follow the creation of highly-charged molecular fragments as a function of time, and probe the dynamics of multi-photon absorption during the transition from a molecule to individual atoms.
The dissociative ionization of N2O by near-single-cycle laser pulses is studied using phase-tagged ion-ion coincidence momentum imaging. Carrier-envelope phase (CEP) dependences are observed in the absolute ion yields and the emission direction of nearly all ionization and dissociation pathways of the triatomic molecule. We find that laser-field-driven electron recollision has a significant impact on the dissociative ionization dynamics and results in pronounced CEP modulations in the dication yields, which are observed in the product ion yields after dissociation. The results indicate that the directional emission of coincident N+ and NO+ ions in the denitrogenation of the dication can be explained by selective ionization of oriented molecules. The deoxygenation of the dication with the formation of coincident N-2(+) + O+ ions exhibits an additional shift in its CEP dependence, suggesting that this channel is further influenced by laser interaction with the dissociating dication. The experimental results demonstrate how few-femtosecond dynamics can drive and steer molecular reactions taking place on (much) longer time scales.
The transition from the near-single to the multi-cycle regime in non-sequential double ionization of argon is investigated experimentally. Argon atoms are exposed to intense laser pulses with a center wavelength around 790 nm and the momenta of electrons and ions generated in the double ionization process are measured in coincidence using a reaction microscope. The duration of the near transform-limited pulses is varied from 4 to 30 fs. We observe an abrupt collapse of the cross-shaped two-electron momentum distribution 17 in the few-cycle regime. The transition to longer pulses is further accompanied by a strong increase in the fraction of anti-correlated to correlated electrons.

In the work for this thesis, a split-mirror-setup was designed and build, which was used to split the XUV laser-pulse of FELs (Free Electron Laser) into two identical pulses from which one can be delayed. With this setup the laser pulses of FLASH, Hamburg and SCSS, Harima(Japan) where characterized temporally, to determine the temporal pulse-structure for subsequent experiments. The intermolecular dynamics of the homonuclear diatomic molecules nitrogen and oxygen were examined and the experimental results were reproduced by classical simulations. In the measurement with oxygen for an energy band of the coincident singly charged ions, an ionization probability was found that depends on the delay between the two XUV-pulses. This can most probably be explained by the autoionization of an excited singly charged molecular state. Subsequently the investigation of the two photon double ionization (TPDI) of deuterium is presented. In the single pulse experiments simulations within the Born-Oppenheimer approximation made it possible to distinguish between the direct and sequential TPDI. In the pump-probe experiments light was shed onto the dynamics of the TPDI. In addition, experiments with strong few-cycle near-infrared (NIR) pulses are presented that examined the carrier envelope phase (CEP) dependence of the non-sequential double ionization of argon. Implementing single-shot CEP-tagging in conjunction with coincidence spectroscopy allowed to achieve unprecedented accuracy in measuring correlated electron dynamics.

Einige der spektakulärsten Beobachtungen unserer Milchstrasse zeigen die filamentären Strukturen in der Umgebung von heissen massereichen O-Sternen. Sobald diese Sterne beginnen zu leuchten, ionisiert ihre ultraviolette Strahlung das umgebende Gas und erzeugt eine heisse HII-Region. Das erhitzte Gas expandiert in die umgebende kalte Molekülwolke. Die dabei entstehende Schockwelle komprimiert das kalte Gas in die auffälligen Strukturen. An den Spitzen dieser Strukturen entstehen neue, masseärmere Sterne. Bis heute ist die präzise Entstehung dieser Regionen nicht vollständig verstanden. Ziel dieser Arbeit ist die Simulation dieser Entwicklung anhand hydrodynamischer Methoden. Dazu wird ionisierende Strahlung in einen Smoothed Particle Hydrodynamics (SPH) Code namens VINE, der vollständig OpenMP-parallelisiert ist, implementiert. Für die Berechnung der Ionisation wird angenommen, dass die betrachtete Region so weit von dem Stern entfernt ist, dass die Strahlung näherungsweise plan-parallel eintrifft. Zunächst wird die Eintrittsfläche in gleich grosse Strahlen unterteilt. Dann wird die Ionisation entlang dieser Strahlen propagiert. Die neue Implementation ist vollständig parallelisiert und trägt den Namen iVINE. Zuerst wird anhand mehrerer Tests die Übereinstimmung von iVINE mit bekannten analytischen Lösungen gezeigt. Danach wird der durch Ionisation induzierte gravitative Kollaps einer marginal stabilen Sphäre untersucht. In allen drei simulierten Fällen mit unterschiedlichem einfallenden ionisierenden Fluss kollabiert die Sphäre. Zusätzlich kann die beobachtete Tendenz, dass jüngere Sterne weiter entfernt von der Quelle der Ionisation entstehen, bestätigt werden. Desweiteren werden Simulationen über den Einfluss ionisierender Strahlung auf turbulente Molekülwolken durchgeführt. Hier zeigt sich, dass die beobachteten, komplexen Strukturen durch die Kombination von Ionisation, Hydrodynamik und Gravitation reproduziert werden können. An den Spitzen der Strukturen wird das Gas stark komprimiert und kollabiert unter dem Einfluss seiner Eigengravitation, genau wie beobachtet. Gleichzeitig treibt die ionisierende Strahlung die Turbulenz im kalten Gas weit stärker als bisher angenommen. Anhand von einer Parameterstudie folgt, dass die entstehenden Strukturen kritisch von dem jeweiligen Anfangsstadium der Wolke zur Zeit der Zündung des O-Sterns abhängen. Dies ergibt die einmalige Gelegenheit, zusätzliche Informationen über Molekülwolken, die ansonsten schwierig zu beobachten sind, in den von O-Sternen stark illuminierten Regionen zu erhalten. Die Implementation ionisierender Strahlung im Rahmen dieser Doktorarbeit ermöglicht die Untersuchung der Einwirkung massereicher Sterne auf ihre Umgebung in bislang Unerreichter Genauigkeit. Die durchgeführten Simulationen vertiefen unser Verständnis der Wechselwirkung von Turbulenz und Gravitation im Rahmen der Sternentstehung. Weitere erstrebenswerte Schritte wären die genauere Berücksichtigung der Kühlprozesse innerhalb der Molekülwolke und die Implementation der Winde massereicher O-Sterne.

A liquid chromatographic-mass spectrometric method for the determination of cortisol in serum using atmospheric pressure electrospray ionization and tandem mass spectrometry is described. During sample preparation, 150 mul of serum were deproteinized with methanol/zinc sulfate followed by on-line solid phase extraction employing column switching. Tri-deuterated cortisol was used as the internal standard. The following transitions were monitored: cortisol, 363 > 309 m/z; d3-cortisol, 366 > 312 m/z. The total run-time was 5 minutes. The method proved linear (0-500 mug/l; r=0.999), precise (total coefficient of variation between 5.0% and 3.2% at a mean cortisol concentration of 15.1 mug/l and 269 mug/l, respectively; n=16) and specific with regard to relevant endogenous and exogenous steroids.

In the present work, the ultrafast dynamics of the photoinitiated electrocyclic ring-opening reactions of 1,3,5-cyclooctatriene and 7-dehydrocholesterol are investigated in a fs pump-probe experiment using ionization as the probe step. Concerning the 1,3,5-cyclooctatriene photoreaction, there are strong arguments for the participation of two different reaction channels (involving a 3-center and a 4-center substructure) which lead to three products. Studying the ring-opening reaction of 7-dehydrocholesterol, which is a substituted cyclic polyene, answers the crucial question to what extent an ultrafast reaction can be slowed down by the influence of a steric factor.
In this work it is demonstrated that mass selected multiphoton ionization is a powerful technique for high resolution spectroscopy, isotope cluster separation and investigation of the structure of van der Waals clusters. The rotationally resolved UV spectra of the benzene-20Ne and benzene-22Ne clusters are selectively measured in a natural isotopic mixture of benzene and benzene-Ne clusters in a cooled supersonic jet. The analysis of these spectra yields accurate values for the rotational constants of both species. From this data it is found that the Ne atom is located on the C6 rotational axis of the benzene ring at an average distance of 3.46 Å with a slight difference for the two isotopes. This distance decreases by 40 mÅ when benzene is electronically excited. The influence of the large amplitude van der Waals vibrations on the average bond length is discussed.
