Decoding Spiking Mechanism with Dynamic Learning on Neuron Population. (arXiv:1911.09309v1 [cs.LG])

A main concern in cognitive neuroscience is to decode the overt neural spike train observations and infer latent representations under neural circuits. However, traditional methods entail strong prior on network structure and hardly meet the demand for real spike data. Here we propose a novel neural network approach called Neuron Activation Network that extracts neural…

Improving Unsupervised Domain Adaptation with Variational Information Bottleneck. (arXiv:1911.09310v1 [cs.LG])

Domain adaptation aims to leverage the supervision signal of source domain to obtain an accurate model for target domain, where the labels are not available. To leverage and adapt the label information from source domain, most existing methods employ a feature extracting function and match the marginal distributions of source and target domains in a…

A Scrambled Method of Moments. (arXiv:1911.09128v1 [econ.EM])

Quasi-Monte Carlo (qMC) methods are a powerful alternative to classical Monte-Carlo (MC) integration. Under certain conditions, they can approximate the desired integral at a faster rate than the usual Central Limit Theorem, resulting in more accurate estimates. This paper explores these methods in a simulation-based estimation setting with an emphasis on the scramble of Owen…

A Flexible Mixed-Frequency Vector Autoregression with a Steady-State Prior. (arXiv:1911.09151v1 [econ.EM])

We propose a Bayesian vector autoregressive (VAR) model for mixed-frequency data. Our model is based on the mean-adjusted parametrization of the VAR and allows for an explicit prior on the ‘steady states’ (unconditional means) of the included variables. Based on recent developments in the literature, we discuss extensions of the model that improve the flexibility…

Binding and segregation of proteins in membrane adhesion: Theory, modelling, and simulations. (arXiv:1911.09352v1 [q-bio.SC])

The adhesion of biomembranes is mediated by the binding of membrane-anchored receptor and ligand proteins. The proteins can only bind if the separation between apposing membranes is sufficiently close to the length of the protein complexes, which leads to an interplay between protein binding and membrane shape. In this article, we review current models of…

AMBRE: A Compact Instrument to Measure Thermal Ions, Electrons and Electrostatic Charging Onboard Spacecraft. (arXiv:1911.09353v1 [astro-ph.IM])

The Active Monitor Box of Electrostatic Risks (AMBER) is a double-head thermal electron and ion electrostatic analyzer (energy range 0-30 keV) that was launched onboard the Jason-3 spacecraft in 2016. The next generation AMBER instrument, for which a first prototype was developed and then calibrated at the end of 2017, constitutes a significant evolution that…

Characterization of TRIGA RC-1 neutron irradiation facilities for radiation damage testing. (arXiv:1911.09374v1 [physics.ins-det])

This paper presents the results of neutron flux measurements at two irradiation facilities of the TRIGA Mark II reactor at ENEA Casaccia Research Center, Italy. The goal of these measurements is to provide a complete characterization of neutron irradiation facilities for accurate and precise dose evaluation in radiation damage tests and, more generally, for all…

Investigating conformation changes and network formation of mucin in joints functioning in human locomotion. (arXiv:1911.09383v1 [physics.bio-ph])

Many different processes take place to facilitate lubrication of the joints functioning in human locomotion system. The main purpose of this is to avoid destroying the articular cartilage. Viscoelastic properties of the joints system are very sensitive on both temperature and concentration changes because of the change in conformation presented in the system proteins and…

The share of manipulable outcomes in social choice problem. (arXiv:1911.09173v1 [econ.TH])

The paper is devoted to study of manipulability of scoring voting rules. We present a conjectural list of inequalities, which are satisfied by a profile if and only if it is manipulable by a coalition $Coal_{\mathcal{A}_k}$ (of members of electorate who prefer $A_k$ over the winner). The conjecture is verified for all positional rules with…

Regression Discontinuity Design under Self-selection. (arXiv:1911.09248v1 [stat.ME])

In Regression Discontinuity (RD) design, self-selection leads to different distributions of covariates on two sides of the policy intervention, which essentially violates the continuity of potential outcome assumption. The standard RD estimand becomes difficult to interpret due to the existence of some indirect effect, i.e. the effect due to self selection. We show that the…
