Performance Degradation of Common Photovoltaic Module Temperature Models From a Lowland Site to a Highland Site in Western China

Energy Science &Engineering, EarlyView.
Four PV module temperature models (Ross, Faiman, PVsyst, and SAPM) in pvlib systematically underestimate module temperature, particularly in high‐altitude environments. Site‐specific recalibration substantially reduces model bias, while the limited transferability of empirical coefficients highlights the need for locally adapted parameterization in ...

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

Food Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

Synthesis of a “Base‐On” Yellow Corrinoid From Vitamin B12

Helvetica Chimica Acta, EarlyView.
A rare “base‐on” yellow corrinoid is obtained from vitamin B12 in a concise semi‐synthesis. Structural and spectroscopic characterization identifies 5,6‐dihydroxyaquacobalamin, in which interruption of the corrin π‐system coexists with dimethylbenzimidazole coordination to cobalt(III), providing new insight into the structure and electronic properties ...

Sizing and concentration analysis of cfDNA using Biabooster technology: Results from a prospective plasma‐based collection of 77 patients with locally advanced unresectable esophageal cancer

International Journal of Cancer, EarlyView.
What's New? This study introduces a novel approach for detecting locally advanced esophageal carcinoma using cell‐free DNA (cfDNA) analysis through a highly sensitive fragmentome assay. Unlike traditional sequencing‐based methods that are limited by the absence of specific mutations in esophageal tumors, our method offers an alternative by quantifying ...

On Sparsity Conditions Guaranteeing a Fractional Coloring

Journal of Graph Theory, EarlyView.
ABSTRACT A graph has an ( a : b ) $(a:b)$ ‐coloring if there exists an assignment from the vertices to subsets of { 1 , … , a } $\{1,\ldots ,a\}$ with size b $b$ such that adjacent vertices are assigned disjoint subsets. Odd girth at least 2 k + 1 $2k+1$ is a necessary condition for a graph to have a ( 2 k + 1 : k ) $(2k+1:k)$‐coloring.

Leveraging Isomerization of Azo Dyes and Imines for the Facile Synthesis of Oxadiazepines and Related Heterocycles

Journal of Heterocyclic Chemistry, EarlyView.
A robust method for synthesizing substituted oxadiazepines and related heterocycles via intramolecular SNAr is detailed. Under mild conditions, this methodology has been leveraged to afford products of varying electronic and aryl nature in up to 99% yields.

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Association Between MRI‐Derived Right‐to‐Left Ventricular Volume Ratio and Regional Left Ventricular Myocardial Dysfunction in Patients With Pulmonary Arterial Hypertension

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Right ventricular (RV) to left ventricular (LV) end‐diastolic volume ratio (RV/LV) is a validated marker of RV dilation in pulmonary arterial hypertension (PAH), yet its impact on LV myocardial function and the underlying mediating pathway is incompletely characterized.

Quantitative UTE MRI Differences in the Meniscus Following ACL Reconstruction: A Prospective Cohort Study Using 3D Ultrashort Echo Time Adiabatic T1rho and Magnetization Transfer Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background ACLR is associated with altered joint loading and increased risk of post‐traumatic osteoarthritis. Conventional MRI has limited sensitivity to early meniscal differences because of short‐T2 signal decay and magic‐angle effects. Purpose To evaluate whether 3D ultrashort echo time imaging‐based adiabatic T1rho (UTE‐Adiab‐T1rho) and ...

Inter‐Group Agreement in Chest Radiographic Quality Assessment: Comparing Final‐Year Students and Experienced Radiographers Across Three Quality Assessment Domains During the COVID‐19 Pandemic

Journal of Medical Radiation Sciences, EarlyView.
Final‐year radiography students and experienced radiographers assessed 70 chest radiographs using structured criteria for positioning, sharpness and anatomical visibility. The level of agreement was good to excellent across all three domains, with an overall ICC of 0.90.
