Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

open access: yesAdvanced NanoBiomed Research, EarlyView.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

Numerical simulation on dynamic migration behaviour of radon of the exposed beach surface under non-isothermal conditions

open access: yesNuclear Engineering and Technology
Seasonal climate change profoundly affects radon release from uranium tailings beaches. This study evaluates radon migration in uranium tailings reservoirs by developing a non-isothermal radon migration model that incorporates freeze-thaw cycles.

A Universal Nucleoside‐to‐Nucleoside‐5′‐Triphosphate Enzyme Cascade Driven by Polyphosphate

open access: yesAngewandte Chemie International Edition, EarlyView.
Nucleoside‐5′‐triphosphates (NTPs) are essential components for the generation of nucleic acids, yet their chemical synthesis is hindered by the low yield of nucleoside phosphorylation. Here, we present a universal, two‐enzyme nucleoside‐to‐NTP cascade that is driven by polyphosphate.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

open access: yesHepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

open access: yesAdvanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

Multiple point rapid measurement method for radon exhalation rate in uranium tailings reservoir and its application

open access: yes四川大学学报. 自然科学版, 2018
Based on the principle of that the equivalent decay constant of perforated accumulation chamber, we propose a new method to rapidly measure the surface radon exhalation rate with multi-point detection technique.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

KARAELMAS YERLEŞKESİ MERKEZ KÜTÜPHANESİ RADON ÖLÇÜMLERİ

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2010
Özet: Bina içindeki doğal radyoaktivitenin başlıca sorumlusu radondur. Radon solunması yoluyla radyasyona maruz kalan kişilerin aldığı dozların hesaplanabilmesi için bina içi radon konsantrasyonunun belirlenmesi önemlidir.

Do multiple peaks in the Radon Transform of westward propagating sea surface height anomalies correspond to higher order Rossby wave Baroclinic modes? [PDF]

open access: yes, 2004
This study examines the presence of multiple peaks from 2 dimensional Fourier and Radon Transform analysis for the entire South Pacific basin from 10 years of sea level anomalies determined from ERS (European Remote Sensing satellite) and T/P altimeter ...
