String Theory Study Links Scattering Equations to K-Identities
Preprint: An analytical study proposes a generating function that organizes an infinite hierarchy of identities in hard string scattering.
Enteral Nutrition Associated With Better Biomarker Trends in ICU Stroke
A seven-day cohort of 73 critically ill adults found different I-FABP and MMP-9 patterns, but clinicians chose the nutrition route rather than assigning it at random.
Missed specialist consultation linked to higher admission on ED return
A peer-reviewed retrospective study at a Turkish university hospital found higher admission among adults returning within 72 hours when specialist input had been missed at the first visit.
Most sampled patients had positive bile cultures, review finds
A review of 16 observational reports on biliary infection and cholangitis found a 77.3% sampling yield, but wide study differences limit the result.
Jazan school study finds stunting in 12.3% of adolescents
A cross-sectional study of 324 adolescents found stunting was more common than thinness and linked increasing age with higher odds, but it could not establish cause.
Protocol sets out test of 20-minute cool-water burn first aid
The plan will track whether emergency and EMS teams deliver cool running water within three hours, alongside grafting and other patient outcomes.
Butterfly genomes point to a patchwork of early reproductive isolation
A comparison across six Heliconius erato populations found the clearest link between chromatin accessibility and genetic divergence at intermediate separation, with important limits.
BL Lacertae flare hints at an ultra-compact gamma-ray source
Preprint: Two 2024-25 flares showed hour-scale changes, while a possible sub-minute signal remained tentative.
Preprint maps two boundary ensembles onto one holographic model
A type IIB calculation assigns the sign of an added topological term to fixed flux or fixed potential, then matches both perturbative boundary partition functions.
Surface Acoustic Waves Track Charge-Density-Wave Transitions
Preprint: Thin films of NbSe3 and 2H-TaSe2 showed temperature-dependent acoustoelectric currents, with polarity changes that varied with wave direction.
Preprint reports a smaller coarse space for multiscale solvers
A two-level method uses high-permeability features for selected small time steps, while full NLMC or an augmented space is proposed for general steps.
AI Training Filter Reports Higher Math and Code Scores
This preprint reports higher benchmark averages from a trajectory filter than from standard on-policy distillation in tested math and code comparisons, with nearly the same training time.
Calculations point to tests of Tcc’s internal structure
Preprint predicts different magnetic moments for compact and molecular versions of the exotic state, while radiative channels offer additional clues.
AI Infers a Simulated Universe’s History From Today’s Matter
Preprint reports close agreement in simplified simulations, but says the trained network is not ready for real data.
AI controller keeps GSM8K accuracy near full budget with far less reasoning
Preprint: AERA came close to a 128-response baseline on an untouched 300-question GSM8K test while using 4.44 responses per question, though broader gains remain uncertain.
BERT leads test of sector-aware cyber threat intelligence routing
Preprint: The study reports that BERT scored best overall on a custom MISPPriv dataset of 872 events, but its averages covered only 10 of 11 sectors.
Streaming solver reports 7% Massart and 32% oblivious noise bounds
An arXiv preprint describes theoretical convergence guarantees for a streaming method using fresh measurements under two corruption models.
Preprint method tracks artery motion better in 4D heart scans
Tests favored a coronary-mask-guided method on artery-motion measures, but the preprint says it cannot reliably capture valve motion and may distort nearby structures when the artery shifts sharply.
openJiuwen posts higher scores than selected systems on two coding tests
An arXiv preprint reports 87.19% on Terminal-Bench 2.1 and 82.6% on SWE-bench Verified, but the comparisons do not isolate the harness alone.
