On the internal modes in sine-Gordon chain

open access: yes, 2004
We address the issue of internal modes of a kink of a discrete sine-Gordon equation. The main point of the present study is to elucidate how the antisymmetric internal mode frequency dependence enters the quasicontinuum spectrum of nonlocalized waves. We

Non-equilibrium theory of the allele frequency spectrum [PDF]

open access: yes, 2006
A forward diffusion equation describing the evolution of the allele frequency spectrum is presented. The influx of mutations is accounted for by imposing a suitable boundary condition.

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

Jeavons Syndrome, Eyelid Myoclonus with Absences (EMA) with Epileptic Status and Hypoactive Delirium

open access: yesActa Medica Martiniana, 2018
The evaluation of electroencephalogram (EEG) and the clinical picture of eyelid myoclonus (EM) with absences (EMA) using classical EEG signal evaluation and power spectral analysis currently presents a major challenge to predict further improvement ...

Infection Control Practices for Vascular Access Management in Hemodialysis: Results From a Nationwide Survey of Japanese National University Hospitals

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Bloodstream infections due to repeated vascular access (VA) puncture and circuit connections remain major concerns in hemodialysis. Therefore, we examined current practices for glove, disinfectant, and personal protective equipment (PPE) use according to VA type in national university hospitals in Japan.

Modeling of Woodworkers’ Exposure to Occupational Noises by Integrating Frequency Spectra Generated by Power Tools: A Pilot Study

open access: yesApplied Sciences, 2020
Woodwork is one of the occupations with high levels of noises. This pilot study attempted to simulate woodworkers’ occupational noise exposure by integrating frequency spectra measured from individual power tools with the respective time of tool use ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
