Differential contributions of synaptic and intrinsic inhibitory currents to speech segmentation via flexible phase-locking in neural oscillators
(2020-01-13)Current hypotheses suggest that speech segmentation – the initial division and grouping of the speech stream into candidate phrases, syllables, and phonemes for further linguistic processing – is executed by a hierarchy ... -
Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention
(2021)Even during sustained attention, enhanced processing of attended stimuli waxes and wanes rhythmically, with periods of enhanced and relatively diminished visual processing (and subsequent target detection) alternating at ... -
Dephosphorylation accelerates the dissociation of ZAP70 from the T cell receptor
(National Academy of Sciences, 2022-02-23)Protein–protein binding domains are critical in signaling networks. Src homology 2 (SH2) domains are binding domains that interact with sequences containing phosphorylated tyrosines. A subset of SH2 domain–containing ... -
BowSaw: inferring higher-order trait interactions associated with complex biological phenotypes
(2021)Machine learning is helping the interpretation of biological complexity by enabling the inference and classification of cellular, organismal and ecological phenotypes based on large datasets, e.g., from genomic, transcriptomic ... -
Tensor decompositions of higher-order correlations by nonlinear Hebbian learning
(2021-12-06)Biological synaptic plasticity exhibits nonlinearities that are not accounted for by classic Hebbian learning rules. Here, we introduce a simple family of generalized nonlinear Hebbian learning rules. We study the ... -
Maximum likelihood estimation and graph matching in errorfully observed networks
(Informa UK Limited, 2021-10-02)Given a pair of graphs with the same number of vertices, the inexact graph matching problem consists in finding a correspondence between the vertices of these graphs that minimizes the total number of induced edge ... -
Ergodic limits, relaxations, and geometric properties of random walk node embeddings
Random walk based node embedding algorithms learn vector representations of nodes by optimizing an objective function of node embedding vectors and skip-bigram statistics computed from random walks on the network. They ... -

Slopes of modular forms and reducible Galois representations: an oversight in the ghost conjecture
The ghost conjecture, formulated by this article’s authors, predicts the list of p-adic valuations of the non-zero ap-eigenvalues (“slopes”) for overconvergent p-adic modular eigenforms in terms of the Newton polygon ... -
p-adic Gross-Zagier formula at critical slope and a conjecture of Perrin-Riou - I
Let p be an odd prime. Given an imaginary quadratic field K = Q(sqrt(−D_K) where p splits with D_K > 3, and a p-ordinary newform f ∈ Sk(Γ0(N)) such that N verifies the Heegner hypothesis relative to K, we prove a p-adic ...
