Sometimes You Gotta Run Before You Can Walk: Run-then-Walk Scheduling Strategy for VLM Autonomous Driving

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Recent VLM-based autonomous driving planners adopt GRPO-style reinforcement learning to optimize driving performance. However, existing GRPO recipes either optimize driving efficiency, risking progress-seeking but unsafe behavior, or enforce early safety constraints, leading to overly conservative behavior; both require lengthy training. To solve these problems, we first reveal two distinct RL regimes: […]

Mass Distribution of M31 from its Rotation Curve up to 167 kpc

Posted by klaurent Peking

Kavli Affiliate: Huawei Zhang | Summary:The mass distribution of the Andromeda galaxy (M31) is fundamental for understanding its dark matter content, assembly history, and dynamical role within the Local Group. However, estimates of M31’s total mass remain quite uncertain, partly because of limited dynamical constraints at large galactocentric radii. Moreover, M31’s recent merger history has […]

High-Dimensional Two-Sample Inference via Marginal Likelihood-Ratio Rank Statistics

Posted by klaurent Peking

Kavli Affiliate: Feng Long| Summary: We develop a rank-based framework for high-dimensional two-sample testing that detects marginal distributional differences beyond means and variances. Three marginal likelihood-ratio statistics generate SUM tests for widespread differences, MAX tests for concentrated departures, and Cauchy combinations for unknown signal sparsity. The procedures retain all pooled ranks and impose no moment […]

Growth and Interface Engineering of Superconducting TiN on Sapphire by Thermal-Laser Epitaxy

Posted by klaurent Cornell

Kavli Affiliate: Grace Xing | Summary:Thermal-laser epitaxy (TLE) extends the accessible pressure, temperature, and growth-rate regimes of conventional molecular-beam epitaxy, enabling in situ laser annealing, high-purity buffer-layer growth, and efficient evaporation of refractory elements. These capabilities make TLE a promising platform for engineering low-loss superconducting resonators and Josephson-junction heterostructures. Here, we study the TLE growth […]

TIC 366240660 – A Dynamically Active Triple With a Very Short Outer Period of 30.5 Days

Posted by klaurent MIT

Kavli Affiliate: Saul Rappaport | Summary:Methods: We analyze TESS photometric data, radial velocity measurements, and eclipse timing variation curves for the triple star system, TIC 366240660, with a photodynamical code to infer the properties of all three stars and orbital motions. Results: With an outer orbital period of only 30.5 d, this is the second […]

The impact of alpha synuclein overexpression on nigrostriatal transmission

Posted by dbos UCSF

Kavli Affiliate: Robert Edwards | Authors: Nikolas Bergum, Andrew Yee, Robert Edwards and Christopher P. Ford | Summary: Accumulation of wild-type α-synuclein in dopamine neurons of the Substantia Nigra pars compacta (SNc) is a pathological hallmark of Parkinson’s disease (PD), which commonly precedes neurodegeneration. Yet how α-synuclein accumulation affects nigrostriatal neurotransmission early in the progression of PD […]

Gone with the wind? Potential gas inflow in the broad-line region of a QSO at $z=0.287$ traced by time-varying Balmer absorption

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:We report spectroscopic observations of a remarkable QSO, J115724.80-000455.56 at $z=0.287$ from the Dark Energy Spectroscopic Instrument (DESI) survey. This QSO exhibits variability in its hydrogen Balmer absorption over a time interval of 10 months in the observed frame between 2021 and 2022. The observed Balmer absorption can be decomposed […]

Bulk OPE Coefficients of the $E$-Series Virasoro Minimal Models

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:We present bulk-primary operator-product coefficients for every Virasoro minimal model with an $E_6$, $E_7$, or $E_8$ modular invariant. Dividing by a universal product of chiral generalized-minimal-model OPE coefficients reduces the conformal bootstrap problem to a finite algebraic problem governed by root-of-unity quantum-group $6j$ symbols. The exceptional factors of the OPE […]
