Hemophilic arthropathy (HA) is a major cause of disability in patients with severe hemophilia A. However, long-term data describing progression to advanced radiographic HA across major joint sites remain limited. We investigated risk factors for progression to advanced HA over ex...

Background SARS-CoV-2 infection can lead to persistent symptoms, known as Post-COVID-19 Condition (PCC). Previous studies on PCC prognosis mainly looked at severe cases in rehabilitation settings and without knowledge about pre-infection symptom levels. Uncertainty remains about...

Anestesia em pacientes com obesidade sarcopênica
A obesidade sarcopênica é uma condição caracterizada pela coexistência de excesso de tecido adiposo e redução da massa e da função muscular, estando associada a maior risco de complicações clínicas e cirúrgicas. No contexto anestésico, essa condição representa um desafio crescent...

O-MoE: Optimized Mixture of Experts for Defensive and Specialized AI Systems
O-MoE is a theoretical framework designed to enhance Mixture of Experts (MoE) architectures by integrating: - **Sequential defensive layers** to counter jailbreak and bias. - **Explicit domain-expert mapping** for specialized tasks. - **Hierarchical Top-K allocation** for adaptiv...

Many fields anticipate regime transitions by comparing a fast, recent estimate of a system's variability to a slower baseline — the moving-average convergence/divergence indicator in finance, the Sahm Rule in macroeconomics, rising-variance indicators in ecology — without a share...

Incoterms® 2020 Through the Lens of Physical Commodity Trading
This research document examines Incoterms® 2020 through the commercial realities of physical commodity trading, integrating legal allocation of risk and obligations with freight economics, marine insurance, logistics execution and operational decision-making. Particular emphasis...

The 240 E8 root vectors, when projected through the 132Hz temporal lattice with phi-synchronized coupling, exhibit spontaneous phase locking that generates stable entanglement networks across root pairs. These networks encode mutual information about future quantum states through...

Yield-point detection can improve the mechanical performance of cancellous bone screws
Appropriate torque applied to screws is an insurance for strong and durable fracture fixation. We compared the mechanical characteristics of four types of bone screws during insertion to facilitate the development of an optimal screw torquing strategy. Bone screws were inserted i...

Abstract Smartphones are now woven into everyday behavior across development, yet much of the evidence linking digital technology to health relies on broad exposure categories, sparse measurement, and age-siloed literatures. As a result, current research is poorly positioned to e...

Abstract Upcycling of polyethylene (PE) can transform waste material into chemically valuable building blocks such as linear alkylbenzenes, with potential use in anionic surfactants. Alkylbenzenes can be formed by tandem hydrogenolysis-aromatization of PE, catalyzed by Pt nanopar...

Structural 9CG Fermion Coefficients and an Internal PMNS Parametrization
This manuscript gives a bounded public formulation of the Steps 6–7 fermion block of the TTOE framework. The first part records a Coxeter/branching-motivated selection of nine rational coefficients, denoted 9CG, along the chain E8 → E6 → D5 → A4 → G_SM. These coefficients are com...

By mapping the 240 E8 root vectors onto a hyperbolic soliton lattice and coupling each node to the 132 Hz φ‑scaled frequency, the lattice self‑organizes into orthogonal Majorana‑like quasiparticle modes. These modes inherit the free‑group topology of the root system, providing in...

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main erup...

Controlled flight of high-thrust ultralight ion-propelled microrobot with integrated sensing
Ion wind technology holds potential for the miniaturization of flying microrobots, generating thrust without mechanical moving parts, enabling simplified and light designs free from high-frequency actuators. Nevertheless, two fundamental challenges have limited its practical impl...

Strong-Coupling Boundary Selection and Super-Exponential Splitting
We study the strong-coupling regime of the four-state entropy–log-gap energy V4,β(λ)=i=1∑4λilogλi+β1≤i<j≤4∑(λi−λj)2log(λi−λj)2 on the probability simplex Δ3={λi≥0,i=1∑4λi=1}. The analysis identifies an explicit strong-coupling boundary selector and reveals a hierarchy of two qual...
