Accurate spatial alignment is essential for any population neuroimaging study, and affine (12 parameter linear/translation) or rigid (6 parameter rotation/translation) alignments play a major role. Here we consider intensity based alignment...
Mathematical modeling of zebrafish social behavior in response to acute caffeine administration [0.03%]

Zebrafish is a model organism that is receiving considerable attention in preclinical research. Particularly important is the use of zebrafish in behavioral pharmacology, where a number of high-throughput experimental paradigms have been pr...
Robust weighted averaging accounts for recruitment into collective motion in human crowds [0.03%]
稳健的加权平均可解释人类人群集体运动中的招募现象

Agent-based models of 'flocking' and 'schooling' have shown that a weighted average of neighbor velocities, with weights that decay gradually with distance, yields emergent collective motion. Weighted averaging thus offers a potential mecha...

Word2vec introduced by Mikolov et al. is a word embedding method that is widely used in natural language processing. Despite its success and frequent use, a strong theoretical justification is still lacking. The main contribution of our pap...

The midbrain superior colliculus (SC) is a crucial sensorimotor interface in the generation of rapid saccadic gaze shifts. For every saccade it recruits a large population of cells in its vectorial motor map. Supra-threshold electrical micr...
Time for a Drink? A Mathematical Model of Non-human Primate Alcohol Consumption [0.03%]
什么时候可以喝酒？非人类灵长类动物饮酒的数学模型

The multiscale model of hepatitis C virus (HCV) dynamics, which includes intracellular viral RNA (vRNA) replication, has been formulated in recent years in order to provide a new conceptual framework for understanding the mechanism of actio...
Methods for measuring swallowing pressure variability using high-resolution manometry [0.03%]
基于高分辨率测压的吞咽压变异性的测量方法研究进展
