3 79 A8f A*. Blockade of GABAergic inhibition increases receptive field (RF) size of most somatosensory cortex (SI) and some ventrobasal thalamus (VB) neurons. To determine if GABA-mediated inhibition controls RF size of cuneate neurons, GAB A and GAB A receptor antagonists were applied by iontophoresis. Glutamate was applied to determine if firing frequency affected RF size. Twenty-nine of thi...

The ionic current underlying anomalous rectification in opener muscle fibers of crayfish was studied under two-electrode voltage clamp. Opener muscle fibers showed a mean resting potential (RP) of -64.8 mV and an input resistance of 0.4 M omega. Hyperpolarizing voltage command pulses from a holding potential (H) of -60 mV evoked an instantaneous voltage-independent linear current (IL) followed ...

Galanin mRNA and peptide are not detectable in normal islets. We studied the effect of galanin antagonists on insulin secretion in the rat beta cell line, RIN5AH, and in perifused rat islets. In RIN cell membranes galanin and its antagonists showed high affinity for 125I-galanin binding sites [Kd: (galanin) 0.03+/-0.01; Ki for galanin antagonists: (C7) 0.12+/- 0.02, (M35) 0.21+/-0.04, and (M40)...

Zusammenfassung Während der Corona-Krise entwickelten die Mitarbeiterinnen Stadtbibliothek Weinheim eine digitale Zaubererschule. So gab es für Weinheimer Kinder trotz aller Einschränkungen einen aufregenden Sommer, Abwechslung sorgte. Alle paar Tage magische Aufgaben zu lösen, Punkte das eigene Haus gab. Am Ende konnte jedes Kind kleinen Preis gewinnen.

We consider (finitary, propositional) logics through the original use of Category Theory: the study of the “ sociology of mathematical objects”, aligning us with a recent, and growing, trend of study logics through its relations with other logics (e.g. process of combinations of logics as fibring [Gab] and possible translation semantics [Car]). So will be objects of study the classes of logics,...

In this paper I explore the dialectics underlying the choice between a geometrical and a field interpretation of the metric tensor gab in general relativity. My aim is to examine the role of a specific type of reasoning process (which I call ‘similarity-based reasoning’) in interpreting gab. In recent years, philosophers of physics have claimed that the problem of choosing between the two inter...

THEOREM 1. Let G be a permutation group on a finite set S of v points. If a, b are distinct points then the set ab of all points fixed by the stabilizer Gab will be called aline. Assume that (i) G is 2-transitive on the points of S; (ii) the number k of points on the line ab satisfies 2 < k < v; (iii) Gab is transitive on the lines containing a and distinct from ab. Then S provided with the set...

In den vergangenen 40 Jahren hat sich das alltägliche Leben durch den Einsatz elektronischer Geräte stark verändert: Gab es früher nur einen Herd, ein Radio, ein Telefon und allenfalls einen Fernseher, so sieht man sich heute Stereoanlagen, Waschmaschinen, Spielkonsolen, Personal Computern, Videogeräten, Fernsehern mit „Bild in Bild“Technologie und vielen anderen mehr oder weniger wichtigen Ger...

Understanding the galaxy-halo connection is fundamental for contemporary models of galaxy clustering. The extent to which haloes' assembly history and environment impact clustering (a.k.a. bias; GAB), remains a complex challenging problem. Using semi-analytic formation model, we study individual contributions different secondary halo properties GAB signal. These are obtained by comparing stella...

Im Rahmen der präventiven Qualitätsmanagement-Methode FMEA (Failure Mode and Effects Analysis) wird jedes Risikoelement durch die Parameter Bedeutung (B), Auftretenswahrscheinlichkeit (A) und Entdeckungswahrscheinlichkeit (E) charakterisiert. Um die Risikoelemente rangieren zu können, wird für jedes Risikoelement eine Risikoprioritätszahl (RPZ) berechnet. Für diese Berechnung existieren verschi...
