Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

The Vanishing Barter Economy in Russia: A Test of the Virtual Economy Hypothesis? Reply to Barry Ickes [PDF]
, 2004 This paper is a reply to Barry Ickes' critique of my paper “Trust versus Illusion: What is Driving Demonetization in Russia?” in which I show that the data reject Barry Ickes' Virtual Economy explanation of barter in Russia in favor of an institutional ...

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Barter, Credit, and Welfare: A theoretical inquiry into the barter phenomenon in Russia [PDF]
This paper develops a model to investigate the welfare implications of barter in Russia and other transition economies during the 1990s. We argue that barter is a welfare-improving phenomenon that acts as a defense mechanism against monetary instability.

Advanced Science, EarlyView.ABSTRACT The LRRK2 G2019S mutation, a Parkinson's disease–linked variant, has been associated with depression‐like phenotypes, but mechanisms remain unclear. We chart age‐dependent behavioral changes and astrocyte reactivity in G2019S mice and define a pathway connecting LRRK2 to TFEB/GDNF signaling, cellular energetics, and inflammation.

Generation of Probabilistic Bits by Exploiting Orthogonal Spin Currents in Magnetic Trilayers
Advanced Science, EarlyView.Fe/Ti/CoFeB trilayers generate orthogonal spin currents that drive stochastic spin–orbit‐torque switching for probabilistic‐bit operation. The switching probability is continuously controlled by the in‐plane magnetic field and drive current, enabling tunable random bit generation.
