Gonadal Steroids: Effects on Excitability of Hippocampal Pyramidal Cells

Abstract: Electrophysiological field potentials from hippocampal slices of rat brain show sex-linked differences in response to 1 X 10(-10)M concentrations of estradiol and testosterone added to the incubation medium. Slices from male rats show increased excitability to estradiol and not to testosterone. Slices from female rats are not affected by estradiol, but slices from female rats in diestrus show increased excitability in response to testosterone whereas slices from females in proestrus show decreased excitability.

Real Options as Engines of Choice and Heterogeneity

Abstract: Four characterizations of options exist: (1) as a component of total firm value, (2) as specific projects, (3) as choices, and (4) as a heuristic for strategic investment. Option value exists when two conditions apply: future choices and potential for proprietary access to outcomes. Narrower boundary conditions are inconsistent with theory and incomplete for application. The option lens has promise for its power to shed economic insight into behavioral processes.

Observation of charge-dependent azimuthal correlations and possible local strong parity violation in heavy-ion collisions

Abstract: Parity (P)-odd domains, corresponding to nontrivial topological solutions of the QCD vacuum, might be created during relativistic heavy-ion collisions. These domains are predicted to lead to charge separation of quarks along the orbital momentum of the system created in noncentral collisions. To study this effect, we investigate a three-particle mixed-harmonics azimuthal correlator which is a P-even observable, but directly sensitive to the charge-separation effect. We report measurements of this observable using the STAR detector in Au + Au and Cu + Cu collisions at root s(NN) = 200 and 62 GeV. The results are presented as a function of collision centrality, particle separation in rapidity, and particle transverse momentum. A signal consistent with several of the theoretical expectations is detected in all four data sets. We compare our results to the predictions of existing event generators and discuss in detail possible contributions from other effects that are not related to P violation.

N-doped graphene film-confined nickel nanoparticles as a highly efficient three-dimensional oxygen evolution electrocatalyst

Abstract: A three-dimensional (3D) catalyst was fabricated by using N-doped graphene films as scaffolds and nickel nanoparticles as building blocks via a heterogeneous reaction process. This unique structure enables high catalyst loadings and optimal electrode contact, leading to a surprisingly high catalytic activity towards OER, which almost approaches that of the state-of-the-art precious OER electrocatalysts (IrO2). Moreover, the catalytic process features favourable electrode kinetics and strong durability during long-term cycling. The dual-active-site mechanism was proposed for this 3D catalyst, i.e., Ni/NiOOH and Ni–N(O)–C are both active sites. The enhanced performance is attributed to synergistic effects of N-doped graphene and Ni, which enhance the activities of both components for OER.

Source Misattributions and the Suggestibility of Eyewitness Memory

Abstract: Although the suggestibility of eyewitness memory is well documented, previous studies have not clearly established the extent to which misled Ss might come to believe they actually remember seeing the suggested details they report. To assess whether Ss confuse misleading suggestions for their "real memories" of a witnessed event, Ss were asked specific questions about their memory for the source of suggested items. The results of 5 experiments showed that misled Ss do sometimes come to believe they remember seeing items that were merely suggested to them, a phenomenon we refer to as the source misattribution effect. Nevertheless, the results also showed that the magnitude of this effect varies and that source misattributions are not an inevitable consequence of exposure to suggestions.
