Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Concurrency Models with Causality and Events as Psi-calculi [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
Psi-calculi are a parametric framework for nominal calculi, where standard calculi are found as instances, like the pi-calculus, or the cryptographic spi-calculus and applied-pi.

Misner String Entropy [PDF]

open access: yes, 1999
I show that gravitational entropy can be ascribed to spacetimes containing Misner strings (the gravitational analogues of Dirac strings), even in the absence of any other event horizon (or bolt) structures.

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.

A Cartesian closed category of event structures with quotients

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We introduce a new class of morphisms for event structures. The category obtained is Cartesian closed, and a natural notion of quotient event structure is defined within it.

Structural Influence on Radiation-induced Single-event Effects in SiC MOSFETs: Comparative Analysis of Planar and Trench Designs

open access: yesYuanzineng kexue jishu
The single-event susceptibility of three silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) power devices structures (planar, trench and double trench) is researched by the technology computer-aided design (TCAD) simulation.

Deterministic Behavioural Models for Concurrency [PDF]

open access: yes, 1993
This paper offers three candidates for a deterministic, noninterleaving, behaviour model which generalizes Hoare traces to the noninterleaving situation.

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.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Multiple-Event Catastrophe Bond Pricing Based on CIR-Copula-POT Model

open access: yesDiscrete Dynamics in Nature and Society, 2018
Catastrophe events are attracting increased attention because of their devastating consequences. Aimed at the nonlinear dependency and tail characteristics of different triggered indexes of multiple-event catastrophe bonds, this paper applies Copula ...
