Iron and Manganese Show Different Surface Responses in Lead-Tin Selenide
An arXiv preprint reports that submonolayer Fe and Mn deposits were associated with Rashba splitting on one crystal face and closer Dirac cones on another.
Text May Help Forecasts Only When Recent Values Are Not Enough
Preprint study finds that extra context matters most when recent history does not contain all the useful signal.
Flexible Smoothing Maps Score Higher in One Denoising Test
An arXiv preprint reports higher image-quality scores for a less regular map, while paired MRI tests showed little difference when maps were swapped.
Coupled Dirac valleys point to a new critical behavior
Preprint: The analysis reports a finite-coupling fixed point with broken Lorentz invariance, while the symmetry is asymptotically restored as the number of valleys grows.
Study finds three recurring shape patterns in normal corneas
Preprint: An analysis of 8,609 maps suggests three corneal shape categories that could guide future biosynthetic implant design.
Quantum-walk design reports lower model-based CNOT upper bounds
Preprint: An arXiv analysis compares decomposed and naive quantum-walk circuits, reporting lower model-based CNOT upper bounds in the stated examples.
SOPO-CD posts large speed gains in robotic placement tests
Preprint reports faster Tangram, Tetris and 3D bin-packing tests, plus an open-loop robot demonstration.
Preprint reports stronger attack resistance for a federated AI defense
A computational study links transferable attacks to differences between models and client data, then reports higher adversarial accuracy than federated adversarial training in tested settings.
Preprint Extends Path Abstraction to Expected Rewards in Finite Markov Models
The framework covers substochastic, discrete-time models and stores target-reaching probability with normalized expected reward for reachable absorbing targets.
Study Reports a 75-Fold Gap in Arabic Manuscript Annotation
A preprint describes a human-reviewed pipeline for 14 historical Arabic books, using clean reference transcriptions as its starting point.
Theoretical models find the best helper need not be the coldest
Preprint: Theoretical models compare auxiliary states chosen to minimize a target's slowest relaxation mode with states optimized for a fixed readout time.
Laser choices shape prospects for a future 10 TeV photon collider
Preprint: Simulations find near-optical lasers deliver more luminosity, while an X-ray option creates a narrower high-energy peak.
Self-Driving Models Improve in Tests with Local Drone Data
An arXiv preprint reports lower offline errors after self-driving models were trained on aerial traffic data from Songdo, South Korea.
Offline co-signing protocol links signatures to device provenance
Preprint outlines a two-device system that can be checked offline, but leaves major security and identity questions open.
Math Proof Settles Frankl's Conjecture at Height Four
Preprint: A theoretical study proves the empty-set-free result through height four while narrowing, but not resolving, the height-five case.
Small VTOL Simulations Show Different Wing-Rotor Trade-offs
This preprint models a propeller and wing in cruise and hover, with cruise efficiency associated with advance ratio and hover metrics more closely associated with RPM.
Frozen blood-cell AI models falter when images change
Preprint: A benchmark of 15 image encoders found steep losses in cross-dataset accuracy and confidence, while CBR delivered a limited gain.
Quantum compression saves qubits, but shifts costs elsewhere
Preprint analysis finds that packing many binary variables into fewer qubits can shrink signal margins and increase decoding or measurement costs.
AI Simulations Link Rival Persuaders to Unsettled Belief Paths
Preprint: In 4,400 simulated runs, competing messages were associated with different belief endpoints and a reversal in how network density tracked upward movement.
