30.11.2025 by pricpr

The study details two distinct data structures-lists formatted as $txt$ and graphs represented as $g6g6$-demonstrating how information can be organized and presented through differing, yet complementary, methodologies.

New research explores the interplay between graph architecture and spectral properties, pinpointing graphs that maximize and minimize key connectivity measures.

Watching Neon Grow: Real-Time Control for Better Qubits

30.11.2025 by pricpr

The study demonstrates how varying the initial gas quantity during film deposition-specifically, 0.008 mol versus 0.003 mol-dictates the resulting material’s phase trajectory, transitioning either through a liquid intermediate phase or directly to solid deposition at a cooling rate of 0.07 K/min, as evidenced by shifts in resonator frequency and inferred film thickness measurements.

Researchers have developed a method for monitoring neon film growth in real-time, paving the way for more reliable electron-on-neon qubits.

Unlocking Secrets of Active Galaxies with Light Curve Analysis

A new software package is poised to transform our understanding of active galactic nuclei by efficiently modeling their ever-changing brightness across multiple wavelengths.

Agents That Remember: Scaling Lifelong Learning in Language Models

30.11.2025 by pricpr

The ReMem agent operates through iterative search, synthesis, and evolution of learned memory across tasks, facilitated by a three-module architecture-reasoning and decomposition, memory refinement through retrieval, pruning, and organization, and environmental execution-to dynamically adapt and perform.

New research introduces a comprehensive benchmark for evaluating how effectively AI agents can learn from ongoing experience and refine their own memories.

Prime Numbers Unlock Efficient High-Dimensional Data Mapping

Bridging Fidelity and Speed in Simulation

30.11.2025 by pricpr

$A comparative study of coupling methods for a 3D nonlinear hyperelastic tension problem demonstrates that an O-SAM-based coupling achieves comparable predictive accuracy-as measured by the average von Mises stress $ \sigma_{vm} $ in domain $ \Omega_{2} $ at the final time-to a full Schwarz coupling utilizing QOpInf, even surpassing the latter when limited to a single Schwarz iteration.$

A new hybrid approach combines high-accuracy and reduced-order models to dramatically accelerate complex simulations without sacrificing precision.

Untangling the Latent Space: A New Criterion for Disentangled Representations

30.11.2025 by pricpr

Researchers have developed a novel method to encourage clearer, more independent factors in learned representations, improving performance under complex, nonlinear conditions.

Entangled X-rays Reveal Core-Level Secrets

30.11.2025 by pricpr

New research demonstrates how the quantum link between emitted X-rays and photoelectrons varies depending on the atom’s inner-shell excitation, opening doors to more precise X-ray spectroscopy.

Cosmic Dawn in Sight: First Data from HERA’s Upgrade

30.11.2025 by pricpr

New observations with the upgraded HERA radio telescope are beginning to constrain the earliest moments of cosmic structure formation.

Driven Spins: How Long-Range Interactions Dictate Thermal Chaos

29.11.2025 by pricpr

$The entanglement entropy, $S_{N/2}$, was computed for a system with $N=800$ dimensions, revealing that for large values of $\alpha$, estimations of $S_{N/2}$ across varying subsystem sizes, $N_A$, rely on semi-analytical fitting, while $\alpha=0$ corresponds to a random permutation within a symmetric subspace of $N+1$ dimensions.$

New research reveals how periodically driven spin systems transition from order to thermalization depending on the strength of interactions between particles.
