After a month long loan deal expired, Edinburgh returned John Robins. So Robins, free from the Scottish capital's creative buzz and extortionate rental prices returned to the studio... to broadcast to Britain and the world. But today he was not with his companion of norm. With Elis away on a sojourn for Isy's birthday, Lou Sanders filled his boots to a supreme degree. The expert on self herself. And what a breath of fresh electric car air she brought. Meanwhile, John tabled some big stepdad energy, we interact with a spirited antipodean and, in a world first, Dave gets shouted down while reading the rules to a Made Up Game.

Did you know apparently polar bear fur is clear?! That can't be true right? Well how do you feel about during an expert investigation team to find out! It's time to become honorary worms! So pack up your Jacob's Crackers and a health supply of Dairy Lea and get ready to get on the road! Road trip! 

Jeanne Lazzarini, who has visited us before to talk about tessellations, discusses a new mathematical discovery that even earned a mention on Jimmy Kimmel. It's a shape that can be used to fill the plane with no gaps and no overlaps and, most remarkably, no repeating patterns. --- Send in a voice message: https://podcasters.spotify.com/pod/show/the-art-of-mathematics/message

C., Dogruoz, E., Jordan, P. M., Verbarschott, C., Callier, T., Sobinov, A., Okorokova, E. V., Prasad, D., He, Q., Liu, F., Miller, J. P., Lee, R.

Abstract: When we interact with objects, signals from the hand convey information about the objects and our interactions with them. A basic feature of these interactions, the locations of contacts between the hand and object, is often only available via the sense of touch. Information about locations of contact between a brain-controlled bionic hand and an object can in principle be signaled via intracortical microstimulation (ICMS) of somatosensory cortex (S1), which evokes touch sensations that are localized to a specific patch of skin. To provide intuitive location information, tactile sensors on the robotic hand drive ICMS through electrodes that evoke sensations at skin locations matching sensor locations. This approach requires that ICMS-evoked sensations be focal, stable, and distributed over the hand. To systematically investigate the localization of ICMS-evoked sensations, we analyzed the projected fields (PFs) of ICMS-evoked sensations - their spatial extent - from reports obtained over multiple years from three participants implanted with micro-electrode arrays in S1. First, we found that PFs vary widely in their size, are highly stable, and are distributed over large swaths of each participants hand. Second, PFs increase in size as the amplitude and frequency of ICMS increases. Third, leveraging participants with residual sensation, we found that PF locations match the locations of the receptive fields (RFs) of the neurons near the stimulating electrode. Furthermore, PFs tended to be subsumed by the corresponding RFs. Fourth, multi-channel stimulation yielded a PF that reflected an approximately additive combination of the PFs of the component channels. By stimulating through electrodes with largely overlapping PFs, then, we could evoke more focal sensations, experienced primarily at the intersection of the component PFs. To assess the functional consequence of this phenomenon, we implemented multi-channel ICMS-based feedback in a bionic hand and demonstrated that the resulting sensations are more localizable than are those evoked via single-channel ICMS.

En el bloque en el cual nos encargamos de reseñar obras del profundo arte de las viñetas, nos encontramos con el primer número de The Tessellation, comic del sello independiente Martian Lit. Co-creado por el guionista Mike Phillips y el dibujante Hernán González, nos relata una trama de realidades paralelas, y cómo hasta la más pequeña decisión puede desencadenar hechos totalmente diferentes. Además, contamos con el testimonio del mismo González, quien nos cuenta acerca del proceso creativo y de los planes a futuro.

Jace chats with Mike Philips about his current Kickstarter campaign. It is a great story idea with a clever structure. We've all thought about how the choices & events in our lives have led us down certain paths and wondered how things might have been different if we had chosen or acted differently. Well Mike's comic Tessellation attempts to answer that question for his main character as we look at several different timelines that diverge from a single event. Join us to learn more about it.

Um Galaxien, Galaxienhaufen oder noch größere Strukturen im Universum detailliert zu simulieren, benötigt man eine korrekte Simulation des in diesen Objekten vorhandenen Gases. Eine Möglichkeit zur Simulation dieses Gases bietet das etablierte Verfahren ``Smoothed Particle Hydrodynamics (SPH)''. Diese Methode empfiehlt sich besonders wegen ihrer intrinsischen geometrischen Flexibilität und ihrer adaptiven Auflösung. Neuere Untersuchungen zeigten aber, dass SPH in Situationen, in denen große Dichtesprünge auftreten, ungenau wird. Hier kann es zu einem unphysikalisch verlangsamten Wachstum von hydrodynamischen Instabilitäten kommen. Diese Probleme von SPH können vor allem auf systematisch bedingte Ungenauigkeiten in der Dichtebestimmung dieser Methode zurückgeführt werden. Um diese Probleme zu vermeiden, haben wir eine neue ``Voronoi Particle Hydrodynamics'' (VPH) genannte Methode enwickelt, um die Hydrodynamik zu simulieren. Dabei wird die Dichte der Simulationsteilchen mit Hilfe eines zusätzlichen Gitters bestimmt. Dieses Gitter ist eine Voronoi Pflasterung, die auf auf den Positionen der Teilchen basiert. Mit Hilfe dieses Prinzips können hydrodynamische Instabilitäten korrekt simuliert werden. Situationen, in denen Scherströmungen entlang großer Dichtesprünge auftreten und zu hydrodynamische Instabilitäten führen, sind besonders ungünstig für SPH, da es hier zu großen Ungenauigkeiten kommen kann. Eine Anwendung, in der solche Situationen zu erwarten sind, ist der Einfall einer Galaxie in einen Galaxienhaufen. Dabei verliert die Galaxie aufgrund des anströmenden Galaxienhaufen-Gases zunehmend Gas an den Galaxienhaufen. Da SPH aufgrund seiner Dichtebestimmung diesen Prozess nicht korrekt simuliert, ermittelt SPH einen zu geringen Verlust von Gas. Wir konnten dies mit Hilfe unserer Simulationen belegen. Wir haben diese Resultate sowohl mit Simulationen von Galaxien, die in einen Galaxienhaufen fallen, als auch mit kosmologischen Simulationen von sich bildenden Galaxienhaufen überprüft. Dort bestätigte sich, dass in SPH der Gasverlust der einfallenen Galaxien zu gering ist. Desweiteren ist der Gasverlust in den AREPO Simulationen stets am höchsten, während VPH eine mittlere Stellung einnimmt. Wir konnten ingesamt zeigen, dass VPH in Situationen mit großem Dichtekontrast eine Verbesserung zu SPH darstellt. Auch wenn unsere Resultate keine vollständige Übereinstimmung mit dem Gitter-basierten AREPO Code zeigen, stellen sie doch eine wichtige Annährung zwischen Teilchen- und Gitter-basierten hydrodynamischen Verfahren dar. VPH empfiehlt sich vor allem als eine gegenüber SPH verbesserte Methode zur Simulation von hydrodynamischen Prozesssen in kosmologischen Problemen.
