Spectral learning of Bernoulli linear dynamical systems models Open
Latent linear dynamical systems with Bernoulli observations provide a powerful modeling framework for identifying the temporal dynamics underlying binary time series data, which arise in a variety of contexts such as binary decision-making…

Opponent control of behavior by dorsomedial striatal pathways depends on task demands and internal state Open
A classic view of the striatum holds that activity in direct and indirect pathways oppositely modulates motor output. Whether this involves direct control of movement, or reflects a cognitive process underlying movement, remains unresolved…
Mice alternate between discrete strategies during perceptual decision-making Open
Classical models of perceptual decision-making assume that subjects use a single, consistent strategy to form decisions, or that strategies evolve slowly over time. Here we present new analyses suggesting that this common view is incorrect…

The structural phases and vibrational properties of Mo <sub>1−x</sub> W <sub>x</sub> Te <sub>2</sub> alloys Open
The structural polymorphism in transition metal dichalcogenides (TMDs) provides exciting opportunities for developing advanced electronics. For example, MoTe2 crystallizes in the 2H semiconducting phase at ambient temperature and pressure,…

Phonon Anharmonicity in Bulk <i>T</i> <sub><i>d</i></sub> -MoTe<sub>2</sub>. Open
We examine anharmonic contributions to the optical phonon modes in bulk T d -MoTe2 through temperature-dependent Raman spectroscopy. At temperatures ranging from 100 K to 200 K, we find that all modes redshift linearly with temperature in …
