Research on a Ka‐band large‐orbit gyro‐TWT with periodic dielectric‐loaded structure

Electronics Letters
This paper presents a design of a gyro‐TWT operating in the large‐orbit electron beam mode, with the aim of reducing the working magnetic field while ensuring operational efficiency.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Screen chaotic motion by Shannon entropy in curved spacetimes

European Physical Journal C: Particles and Fields
We find a novel characteristic for chaotic motion by introducing Shannon entropy for periodic orbits, quasiperiodic orbits, and chaotic orbits. We compare our approach with the previous methods including Poincaré section, Lyapunov exponent, fast Lyapunov

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

A Disk-originated 329 Day Quasiperiodic Oscillation in the Seyfert 1 Galaxy J1626+5120

The Astrophysical Journal Letters
The Seyfert 1 galaxy J1626+5120 is estimated to host a 10 ^8 M _⊙ black hole (BH) accreting at Eddington ratio ${\dot{m}}_{\,\rm{Edd}\,}\approx 0.043$ . Its long-term multiband light-curve data show flicker-like variations, but in a well-sampled g -band ...

Analysis of motion in RTBP with variable mass based on Loglogistic distribution

Results in Physics
Recent literature has stated that the physical characteristics of natural satellites in Jupiter’s Ananke and Carme groups, such as mass, exhibit the same statistical law, with the best-fitting distribution being a Loglogistic distribution.

Risk Prediction Models for Recurrence After Curative Treatment of Early‐Stage or Locally Advanced Lung Cancer: A Systematic Review

Aging and Cancer, EarlyView.
This systematic review synthesizes prognostic models for survival and recurrence in resected non‐small cell lung cancer. While many models demonstrate moderate to good discrimination, few are externally validated and reporting quality is variable, limiting clinical applicability and highlighting the need for robust, transparent model development ...

Tracking Motor Progression and Device‐Aided Therapy Eligibility in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterise the progression of motor symptoms and identify eligibility for device‐aided therapies in Parkinson's disease, using both the 5‐2‐1 criteria and a refined clinical definition, while examining differences across genetic subgroups.

Experimental evidence for invariant solutions mediating transitions from metastable turbulent regimes

Physical Review Research
We present direct experimental evidence for turbulence visiting the neighborhoods of simple invariant solutions in phase space, immediately preceding and during rapid transitions between metastable flow regimes characterized by opposite large-scale ...
