Relations Among Different Inequality Measures in Complex Systems: From Kinetic Exchange to Earthquake Models

arXiv:2512.18408v4 Announce Type: replace Abstract: We present a numerical study of several inequality measures across two kinetic wealth exchange models with extreme inequality features (namely the Banerjee model, and the Chakraborti or Yard Sale model) and two earthquake simulating models (namely the Chakrabarti Stinchcombe two fractal overlap model and the nonlinear dynamical Burridge Knopoff model). For each model we compute numerically the Lorenz function for the respective models...

A Kinetic Theory of Encounter-Based Information Propagation in Multi-Robot Systems

arXiv:2606.02296v1 Announce Type: new Abstract: Multi-robot systems cannot assume persistent network connectivity. We study this problem through target tracking, where performance depends on how quickly target information is sensed, transported through the team, and used before it becomes stale. When robots exchange information only through physical encounters, tracking becomes a kinetic information-transport problem: robot motion induces encounters, encounters carry target-state estimates,...

Inverse energy transfer in decaying MHD turbulence: A shell-to-shell analysis

Announce Type: new Abstract: In decaying magnetohydrodynamic turbulence, energy can be transported from small to large scales, known as inverse transfer. We explore the mechanism behind this phenomenon using shell-to-shell transfer functions.

Wave-mean decomposition of scale-dependent kinetic energy from surface drifters

Announce Type: new Abstract: Separating waves and mean flows is a fundamental challenge in ocean dynamics. Lagrangian filtering of passive-tracer time series into high-frequency wave and low-frequency mean-flow components provides a practical route, as the relevant time scales are often cleanly split in the Lagrangian frame. Here we show that Lagrangian filtering can be applied to surface drifter observations, providing a powerful approach to quantify wave and mean-flow contributions to...

Bessent flips script on shouting Democrat: 'No wonder people are leaving' his blue state

Treasury Secretary Scott Bessent was shouted at during a House Ways and Means Committee hearing this week by a Chicago-area Democrat amid a heated exchange over the Trump economy. Rep. Brad Schneider, D-Ill., followed several other Democrats in condemning rising prices during the Iran conflict, while Bessent repeatedly pushed back on assertions about his policies by pointing to higher commodity prices during the Biden administration. At one point in the exchange, Bessent slammed Schneider's...

Light-induced quantum friction of carbon nanotubes in water

Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.

A menacing message: Why Iran's latest strikes against Israel are different

Iran's latest missile-and-drone barrage against Israel were not militarily noteworthy: a few high-value targets were struck, casualties were unclear, and Israel’s missile defences largely absorbed the onslaught. Yet alarm bells were set off globally. Judging the incident only by its military effect misses the deadly consequential shifts beneath the surface.
