Impact of software tools and kinetic model selection on myocardial blood flow and flow reserve quantitation in 13N‐ammonia PET

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background Quantitative assessment of myocardial perfusion using 13N‐ammonia PET with compartmental modeling enables evaluation of myocardial flow reserve (MFR) and prediction of patient prognosis. However, the reliability of these assessments can depend on the analytical methods used for quantitation.

Spectroscopic ellipsometry study of Cu2ZnSnS4 bulk poly-crystals [PDF]

open access: yes, 2018
The linear optical properties of Cu2ZnSnS4 bulk poly-crystals have been investigated using spectroscopic ellipsometry in the range of 1.2-4.6 eV at room temperature. The characteristic features identified in the optical spectra are explained by using the

Modeling and Verification of 1/f Noise Mechanisms in FAPbBr3 Single‐Crystal X‐Ray Detectors

open access: yesAdvanced Electronic Materials, Volume 12, Issue 9, 11 May 2026.
We demonstratethat surface‐trap‐induced carrier number fluctuations are the dominantmechanism in FAPbBr3 Schottky devices, a conclusion supported by thedistinct defect profiles revealed by Drive‐Level Capacitance Profiling (DLCP). Throughnoise contribution decomposition, it is found that the 1/f noise of thedetector is the key noise source affecting ...

Signatures of Radiation‐Induced Stress and Putative Selection on Immune Targets in Chornobyl Wolves

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Investigating the physiological and evolutionary consequences of contaminant exposure in wild populations is critical for understanding long‐term ecological impacts of anthropogenic change. However, how and why species persist, even thrive, in highly contaminated regions in the absence of humans remains a topic of much debate.

Growth and characterization of Cu2ZnSn(S,Se)4 thin films for solar cells [PDF]

open access: yes, 2012
Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) with their band gap energies around 1.45 eV and 1.0 eV, respectively, can be used as the absorber layer in thin film solar cells.

Sex‐Specific Associations With Abnormal Myocardial Flow Reserve in Non‐Obstructive Coronary Artery Disease: Insights From a Real‐World Cadmium‐Zinc‐Telluride SPECT Study

open access: yesClinical Cardiology, Volume 49, Issue 4, April 2026.
In 393 NOCAD patients undergoing CZT‐SPECT, LDL‐C was independently associated with abnormal MFR, with a significant sex×MDRD‐eGFR interaction. Female patients showed modest LDL‐C discrimination and distinct perfusion–diastolic phenotypes, suggesting sex‐modified cardiorenal‐microvascular relationships in coronary microvascular dysfunction.
