Spectral Concentration and Recovery in Sparse High-Dimensional Random Geometric Graphs
arXiv:2607.14304v1 Announce Type: cross Abstract: We study sparse random geometric graphs generated by connecting pairs of high-dimensional vectors whose inner product exceeds a threshold. The latent vectors are sampled …
Towards a characterization of idempotent Schur multipliers
arXiv:2607.14316v1 Announce Type: cross Abstract: It is conjectured that every idempotent Schur multiplier can be written as a finite sum of contractive idempotents. This conjecture is equivalent to the statement that an…
ViPSAM: Visual Prompting Medical Image Segmentation Using Segment Anything Model
arXiv:2607.14328v1 Announce Type: cross Abstract: In proton therapy planning, respiratory-gated non-contrast CT (NCCT) is commonly used for lesion segmentation; however, accurate delineation remains challenging due to lo…
NeuralChaos: Optimal Adapted Approximation of Square Integrable Predictable Processes
arXiv:2607.14361v1 Announce Type: cross Abstract: We address fundamental challenges in representing and computing $\mathbb{R}^{d}$-valued predictable square-integrable processes over $[0,T]$, collected in the space $\mat…
Circuit complexity lower bounds for quantum spin glasses
arXiv:2607.14384v1 Announce Type: cross Abstract: A central question in quantum information theory is the circuit complexity of states arising from standard many-body models. We study this question for quantum $p$-spin g…
Upwind embedded boundary SBP operators: New high order numerical schemes for arbitrarily shaped domains with Cartesian grids
arXiv:2607.14403v1 Announce Type: cross Abstract: Embedded boundary summation by parts (SBP) methods define finite differencing based derivative operators with the added feature that the boundary need not coincide with a…
On Factorizing Aggregate Counting Distributions into Independent Latent Processes
arXiv:2607.14409v1 Announce Type: cross Abstract: Given only the probability distribution of an aggregate counting variable, what independent latent counting processes are compatible with the observation? Equivalently, w…
Precise sample covariance spectral norm error -- an RDT view
arXiv:2607.14460v1 Announce Type: cross Abstract: We study the sample covariance error of centered Gaussians. A remarkable breakthrough [66] established the correct error scaling order and explicitly revealed the critica…
Perturbation Analysis of Maximal Quantum Leakage
arXiv:2607.14469v1 Announce Type: cross Abstract: Maximal quantum leakage (MQL) is a worst-case information leakage measure that quantifies an adversary's inference advantage gained from accessing quantum encoding of cla…
Full-data accuracy with fewer labels for training and fine-tuning machine-learning force fields
arXiv:2607.14486v1 Announce Type: cross Abstract: Machine-learning force fields (MLFFs) are reliable only near their training distribution, making efficient construction of diverse training sets a major bottleneck for bo…
Moment-Resolved Readout and Reservoir Diversity in Nonequilibrium Langevin Computing
arXiv:2607.14520v1 Announce Type: cross Abstract: Nonlinear thermodynamic computers based on Langevin dynamics exploit thermal fluctuations as a physical substrate for computation. Recent work has shown that quartic-conf…
Right Device, Right Place: Variation-Aware Placement and Design Optimization for Robust Photonic Lattice-Filter Demultiplexers
arXiv:2607.14526v1 Announce Type: cross Abstract: We propose a Bayesian co-optimization framework for robust integrated photonic lattice-filter demultiplexers, jointly optimizing device placement and design parameters un…
Riesz-Kernel Stein Variational Gradient Descent: Renormalized Entropy and Long-Time Particle Limits
arXiv:2607.14527v1 Announce Type: cross Abstract: Stein variational gradient descent (SVGD) transports interacting particles toward a target distribution through deterministic kernelized dynamics. Singular Riesz kernels …
A Modern Multimodal Assistant on a 6 GB 2011 GPU: Stage-Validated, All-GPU CUDA Inference for Fermi
arXiv:2607.14568v1 Announce Type: cross Abstract: A companion study ran a 35B mixture-of-experts model on a 2011 NVIDIA Tesla C2075 (Fermi, sm_20, 6GB) as a GPU-prefill/CPU-decode hybrid, because the 4-bit model did not …
Governing Artificial Intelligence: Public Preferences and Regulatory Options
arXiv:2607.14585v1 Announce Type: cross Abstract: Artificial intelligence (AI) is rapidly transforming economies, societies, and polities, raising fundamental questions about how it should be regulated. Policymakers face…
Acyclic Dichromatic Number of Tournaments: these are the Champions
arXiv:2607.14694v1 Announce Type: cross Abstract: The acyclic dichromatic number of an oriented graph is the minimum size of a vertex-partition such that the digraphs induced by any single part are acyclic, and the orien…
Does Multi-Agent Debate Improve AI Feedback on Research Papers?
arXiv:2607.14713v1 Announce Type: cross Abstract: Probably not, at least for meta-analyses in economics. In a pre-registered, identity-masked, within-paper experiment, the authors of 44 meta-analyses ranked three AI repo…
