Optical and orbital characterization of spherically symmetric static black holes of self-gravitating new nonlinear electrodynamics model
Horizon scale imaging and precision lensing have turned black holes into quantitative laboratories for strong gravity and for non standard electromagnetic physics. We study the optical appearance a...

NanoBench: A Multi-Task Benchmark Dataset for Nano-Quadrotor System Identification, Control, and State Estimation
Existing aerial-robotics benchmarks target vehicles from hundreds of grams to several kilograms and typically expose only high-level state data. They omit the actuator-level signals required to stu...

Optimal Universal Bounds for Quantum Divergences
We identify a universal structural principle underlying the smoothing of classical divergences: the optimizer of the smoothing problem is a clipped probability vector, independently of the specific...

The role of mass loss in constraining quenching time in dwarf galaxies from AGB and RGB star counts
The capability of reconstructing the past star formation history of dwarf elliptical galaxies out of the Local Volume relies on modelling bright stellar populations currently evolving through t...

MissBench: Benchmarking Multimodal Affective Analysis under Imbalanced Missing Modalities
Multimodal affective computing underpins key tasks such as sentiment analysis and emotion recognition. Standard evaluations, however, often assume that textual, acoustic, and visual modalities are ...

CarbonBench: A Global Benchmark for Upscaling of Carbon Fluxes Using Zero-Shot Learning
Accurately quantifying terrestrial carbon exchange is essential for climate policy and carbon accounting, yet models must generalize to ecosystems underrepresented in sparse eddy covariance observa...

A Graph-Based Approach to Spectrum Demand Prediction Using Hierarchical Attention Networks
The surge in wireless connectivity demand, coupled with the finite nature of spectrum resources, compels the development of efficient spectrum management approaches. Spectrum sharing presents a pro...

Polarization transfer in $ψ'\toψππ$: a complete spin density matrix analysis framework
A theoretical framework based on the Spin Density Matrix (SDM) formalism is developed to describe polarization transfer in the decay chain $e^+e^- \rightarrow ψ^\prime \rightarrow ψππ$. Explicit re...

Modeling structure and credit risk of the economy: a multilayer bank-firm network approach
Assessing the resilience of the economy requires accounting for its intrinsic multi-layer nature, by assessing for instance how disruptions at the firm level spread through the production network a...

Materials Acceleration Platform for Electrochemistry (MAP-E): a Platform for Autonomous Electrochemistry
Corrosion testing is slow, labor-intensive, and sensitive to operator technique, limiting the generation of large, high-quality datasets for data-driven materials discovery. We introduce the Materi...

A Swampland-modified Hod bound for charged black holes with exotic matter
In this paper, we study the quasinormal modes (QNMs) of a charged black hole in the presence of both quintessence and a cloud of strings using the Pade-averaged higher-order WKB approximation metho...

Test-time Ego-Exo-centric Adaptation for Action Anticipation via Multi-Label Prototype Growing and Dual-Clue Consistency
Efficient adaptation between Egocentric (Ego) and Exocentric (Exo) views is crucial for applications such as human-robot cooperation. However, the success of most existing Ego-Exo adaptation method...

Exploiting Label-Aware Channel Scoring for Adaptive Channel Pruning in Split Learning
Split learning (SL) transfers most of the training workload to the server, which alleviates computational burden on client devices. However, the transmission of intermediate feature representations...

Two-grid Penalty Approximation Scheme for Doubly Reflected BSDEs
We study penalization coupled with time discretization for decoupled Markovian doubly reflected BSDEs with obstacles \(p_b(t,X_t)\le Y_t\le p_w(t,X_t)\). The DRBSDE is approximated by a penalized B...

Shaken, not stirred: inefficient mixing of CM- and CI-like materials
A recent study suggests that CM chondrite-like planetesimals formed in the vicinity of Saturn, in a pressure bump outside the gap carved by proto-Jupiter. While a fraction of these objects was impl...

Event-by-Event Multiplicity Fluctuations in Heavy-Ion Collisions Using Modified HIJING Monte Carlo Generator
This work presents an analysis of event-by-event multiplicity fluctuations as a sensitive tool for diagnosing the state of matter produced in relativistic heavy-ion collisions. Using a modified ver...

Idempotent Slices with Applications to Code-Size Reduction
Given a value computed within a program, an idempotent backward slice with respect to this value is a maximal subprogram that computes it. An informal notion of an idempotent slice has previously b...
