TL;DR: A systematic theoretical study of the BCS-BEC crossover in two-dimensional Fermi gases with Rashba spin-orbit coupling shows that the SOC enhances the formation of the bound state: the binding energy E(B) and effective mass m(B), which grows along with the increase of the SOC.
Abstract: We present a systematic theoretical study of the BCS-BEC crossover in two-dimensional Fermi gases with Rashba spin-orbit coupling (SOC). By solving the exact two-body problem in the presence of an attractive short-range interaction we show that the SOC enhances the formation of the bound state: the binding energy E(B) and effective mass m(B) of the bound state grows along with the increase of the SOC. For the many-body problem, even at weak attraction, a dilute Fermi gas can evolve from a BCS superfluid state to a Bose condensation of molecules when the SOC becomes comparable to the Fermi momentum. The ground-state properties and the Berezinskii-Kosterlitz-Thouless (BKT) transition temperature are studied, and analytical results are obtained in various limits. For large SOC, the BKT transition temperature recovers that for a Bose gas with an effective mass m(B). We find that the condensate and superfluid densities have distinct behaviors in the presence of SOC: the condensate density is generally enhanced by the SOC due to the increase of the molecule binding; the superfluid density is suppressed because of the nontrivial molecule effective mass m(B).

TL;DR: A method that estimates the strength of neuronal oscillations at the cellular level, relying on autocorrelation histograms computed on spike trains, and provides a measure, termed confidence score, that determines the stability of the oscillation score estimate over trials.
Abstract: We present a method that estimates the strength of neuronal oscillations at the cellular level, relying on autocorrelation histograms computed on spike trains. The method delivers a number, termed oscillation score, that estimates the degree to which a neuron is oscillating in a given frequency band. Moreover, it can also reliably identify the oscillation frequency and strength in the given band, independently of the oscillation in other frequency bands, and thus it can handle superimposed oscillations on multiple scales (theta, alpha, beta, gamma, etc.). The method is relatively simple and fast. It can cope with a low number of spikes, converging exponentially fast with the number of spikes, to a stable estimation of the oscillation strength. It thus lends itself to the analysis of spike-sorted single-unit activity from electrophysiological recordings. We show that the method performs well on experimental data recorded from cat visual cortex and also compares favorably to other methods. In addition, we provide a measure, termed confidence score, that determines the stability of the oscillation score estimate over trials.

TL;DR: In this article, the universal curve for α-decay and cluster radioactivities based on the fission approach of these decay modes is compared with the universal decay law derived using α-like R-matrix theory for a total of 534 α-emitters in four groups: even-even, even-odd, odd-even and odd-odd.
Abstract: The universal curve for α-decay and cluster radioactivities based on the fission approach of these decay modes is compared with the universal decay law derived using α-like R-matrix theory for a total of 534 α-emitters in four groups: even–even, even–odd, odd–even and odd–odd. The standard deviations of calculated half-lives from the experimental ones are comparable in the two cases. Large absolute values of deviations from experimental data which are found in the neighborhood of magic numbers of neutrons 126, 162 and 172, and magic numbers of protons 82 and 108 are explained by a part of shell effects which are not taken into account.
