The Bronx in the 1970s was a perfect storm of things going wrong in New York City: poor urban planning, white flight, budget cuts to municipal and social services, and discriminatory practices coverged into a pressure cooker -- and the outcome was fiery and devastating. But we can't talk about the Bronx burning without ending on the phoenix that emerged from the rubble: the birth of hip-hop.See omnystudio.com/listener for privacy information.

Abstract: Rhythmic activity is ubiquitous in neural systems, and impedance analysis has been widely used to examine frequency-dependent responses of neuronal membranes to rhythmic inputs. Impedance analysis assumes the neuronal membrane is a linear system, requiring the use of small signals to stay in a near-linear regime. However, postsynaptic potentials are often large and trigger nonlinear mechanisms. We therefore augmented impedance analysis to evaluate membrane responses in this nonlinear domain, analyzing responses to injected current for subthreshold membrane voltage (Vmemb), suprathreshold spike-blocked Vmemb, and spiking in a validated neocortical pyramidal neuron computer model. Responses in these output regimes were asymmetrical, with different phase shifts during hyperpolarizing and depolarizing half-cycles. Suprathreshold chirp stimulation gave equivocal results due to nonstationarity of response, requiring us to use fixed-frequency sinusoids. Sinusoidal inputs produced phase retreat: action potentials occurred progressively later in cycles of the input stimulus, resulting from adaptation. Conversely, sinusoidal current with increasing amplitude over cycles produced a pattern of phase advance: action potentials occurred progressively earlier. Phase retreat was dependent on Ih and Iahp currents; phase advance was modulated by these currents. Our results suggest differential responses of cortical neurons depending on the frequency of oscillatory input in the delta -- beta range, which will play a role in neuronal responses to shifts in network state. We hypothesize that intrinsic cellular properties complement network properties and contribute to in vivo phase-shift phenomena such as phase precession, seen in place and grid cells, and phase roll, observed in non-place cells in hippocampus.

Nick talks to climatologist Dr. Judith Curry, the former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. Her research interests have included hurricanes, atmospheric modeling, air-sea interactions, and a variety of other areas in climate science. She runs Climate, Etc., an online blog focused on climate science. She is also writing a new book called, “Climate Uncertainty & Risk,” which she described towards the end of the podcast. They discuss: how Earth's climate has changed over time and how climate scientists measure this; what computer models are used for in climate science and what their strengths & weaknesses are; tropical storms and severe weather events; CO2, methane, and other greenhouse gasses; different forms of energy, such as oil, natural gas, solar, wind, and nuclear; how she thinks about the tradeoffs between different energy sources in terms of their abundance, environmental impact, costs, and other factors; the politicization of climate science and why certain branches of science are especially prone to it.Support M&M:Sign up for the weekly Mind & Matter newsletter[https://mindandmatter.substack.com/?sort=top]The Amino Co., shop science-back amino acids supplements.

At any given time, there are thousands of icebergs adrift in Antarctica that are hundreds or even thousands of feet across.  For at least fifty years, there has been speculation about whether such icebergs could be towed from the Antarctic to places experiencing freshwater shortages.  The feasibility of such a scheme is still the subject […]

Dr. Ana Vukovic joined us to talk about radome design testing using her computer modeling techniques at the University of Nottingham's George Green Institute for Electromagnetics Research lab. Testing radomes complete with lightning diverter strips is a game-changer. Watch the video version of this episode on YouTube. Her team can test radomes complete with lightning diverter strips to get accurate modeling before physical parts are created. Her team at the University of Nottingham, including Dr. Trevor Benson (trevor.benson@nottingham.ac.uk) and Dr. Phillip Sewell (phillip.sewell@nottingham.ac.uk), are doing incredible work to push the limits of computational modeling in the aerospace and other industries. Contact Dr. Ana Vukovic at ana.vukovic@nottingham.ac.uk or visit the University of Nottingham at https://www.nottingham.ac.uk/research/groups/ggiemr/index.aspx Transcript - Dr. Ana Vukovic on Computer Modeling for Radome Design Testing with Lightning Diverter Strips https://youtu.be/l9o7BwL4dc8 Dan: And here on struck, we talk about everything. Aviation, aerospace engineering, and lightning protection. All right, welcome back. We've got another great episode of struck actually a special episode today. so Allen, we've got another, really good segment with Dr. Ana Vukovich out of the George Green, Center for Electromagnetics Research out of the University of Nottingham. And, what are we, what are we talking about today? Allen Hall: We're talking about a paper that is being published this summer. That. They at the University of Nottingham had put together, which looks like the performance of radar homes installed sort of on aircraft with the lightning protection on the radar. And so usually when we model, we're just looking at the, our performance of itself of the radar, basically the thickness and the dielectric constant of the radar and whatever the antenna is behind it. That's basically the basics of trying to get an antenna pattern out of that. Cause you can model the antenna and you can model the radon and then you can kind of combine the two together to simulate. What that would look like RF wise, the real key to the University of Nottingham's approach is that they can actually install lightning protection on the radar, which is the next level up, because the RF performance of the radar is not just, or the radar itself, but everything else that's on it, including paint coatings and diverted strips and whatever else is going to be on the radar, erosion boots, things of that sort. That's been very difficult to model in the past, but Nottingham has broken through that barrier. And is able to not only simulate, the effects of diverted stress, but like accurately do it. So their, their modeling has very F really, really capable meshing of small objects, but it also does larger object too. So you can get to the fine detail, a diverter strip, like a segment, a diverter strip--like StrikeTape--on top of a larger radome, like on an Airbus A380 radome and get performance numbers, which is unheard of. Dan: So this paper, Impact of In-situ Radome on Lighting Diverter Strips on Antenna Performance was written by dr. Ana Vukovic, Dr. Phillip Sewell and Dr. Trevor Benson. So I mean, a pretty impressive group. And what they're doing with computer modeling is, is pretty special. Allen Hall: It's way off the charts special right now. And this is sort of your dream as an RF designer to have this kind of capability at your fingertips. And. We really haven't had that much power to do things like this without having essentially a supercomputer now, because of the way that a Nottingham is broken up their mesh and able to handle some of those more discrete problems. Now we have the capability of actually modeling an antenna and a radar come in in an aircraft without having all the pieces there. So we don't have to build it and test it. We just model it, try it. And if you don't like it,

Dr. Ana Vukovic from the University of Nottingham's George Green Institute for Electromagnetics Research joined us to talk about her incredible computational modeling work. She shared examples of how their computer modeling technology can greatly reduce the time and expense involved in testing the electromagnetic properties of new parts, including lightning protection, HIRF and RF designs. Her team at the University of Nottingham, including Dr. Trevor Benson and Dr. Phil Sewell, are doing amazing things to improve efficiency of parts engineering in the aerospace industry, among others. What previously might take weeks and months to develop and test can now be tested in as a little as a day using their unique computational modeling techniques.

Struck Podcast EP14: Dr. Ana Vukovic from the University of Nottingham on Computer Modeling https://youtu.be/q_3hn0dbdcM Here on Struck, we talk about everything aviation, aerospace engineering and lightning protection. Alright, Allen, we got a guest today from across the pond. So who are we talking to today? Allen Hall: It's Ana Vukovic with the University of Nottingham. She is in computation modeling. And they have developed some really interesting software and technology over the last couple of years so that we can now. Really simulate aircraft, uh, installations, even on wind turbines, we can do some of the complex geometries we couldn't do before, because we didn't have the techniques. So on I and our group over there have developed these techniques and, uh, [00:01:00] surely gonna open a whole number of doors in aerospace. And obviously is we're all coming out of COVID. Uh, one of the things that's really trying to save costs and move programs forward. Well, this is one way to do it. Dan: Yeah. So it was interesting conversation. Obviously I'm not an engineer, so me being the outsider, it, it still boils down and it makes a lot of sense. So obviously when you're trying to engineer new parts for an aircraft, it's incredibly expensive, takes incredibly expensive people to do so it takes a lot of time. And when you're ready to test these systems together, so not just like an antenna, but the whole radon with antenna inside and diverter strips on the outside of this whole complex thing currently, you guys have to actually build it. And then in most of this is actually put on the plane just to test it, to maybe see if, if there's an effect at all, or if there's like an incremental effect, which seems like a terrible waste of time and money. And so it is it's can do this on a computer modeling or on computer modeling. Yeah. And just be done with it, which [00:02:00] sounds like, I mean, just makes a ton of sense. Allen Hall: It makes a lot more sense. You're going to get better products at the end of the day and less expensive products, uh, in the computational world. We've been trying to get here for since the 1970s, mid 1970s. So it's been a long haul and obviously the computational power we have now. Helps because we doing a lot of computations, but a lot of this is trying to cut down the computations. And then the techniques that have been developed at the university of Nottingham reduce the amount of computational time it takes to do some of these complex problems. So not only do we have the horsepower now, but we're also smarter about the way we use the horsepower, which cuts down on cost. Dan: And so she, they have more capabilities then. So in the industry, COMSOL is the software that. You can have a computer at your desktop, you know,

You might be surprised to learn that the Coast Guard Search and Rescue Mission employs only one oceanographer. But what a heck-of-an oceanographer he is. After years of detailed study of how vessels drift in coastal waters, he pioneered a computer modeling program. It enables the Coast Guard to rescue people more quickly and efficiently. Now that oceanographer is a finalist in this year's Service to America Medals program. Art Allen joined Federal Drive with Tom Temin to talk about his work.

We've got a really good interview today that I think takes us further into the whole 3D scanning and creating a real product out of that exploration. I was at CEO Space, which is our networking and executive and entrepreneurship education forums we participate in quite a few times a year. They have five of them. We've done two this year or something like that already. It's just one of those things where you meet people and they know that we are in the 3D printing industry and they bring me things. LoraLee Harmon, who I absolutely love, she's a CEO Space Club President and such a great connector, excitedly runs up to me on the last day of CEO Space and has these 3D print figurines in her hand of a bride and groom. She had some with her. I'm sitting there looking at them going, “I've never seen this good quality before. The face's expression is there. The colors look vibrant.” I was shocked at that and she goes, “I know this woman of 3DTransformations, Barbara Wood. Would you like to meet her? Maybe you could interview her.” I go, “Maybe? We're definitely going to interview her. I may even go and order one of these for my daughter's wedding.” She was explaining a little bit about Barbara Wood and 3DTransformations out of Charleston, South Carolina. It's more than figurine printing to me. She started the business with this vision of really helping to give people something to feel and touch about people they love. Especially, started out in helping the blind to be able to have a better experience through 3D prints of loved ones and things like that.
