Development of a PCI Express Based Readout Electronics for the XPAD3 X-Ray Photon Counting Image [PDF]

open access: yesarXiv, 2011
XPAD3 is a large surface X-ray photon counting imager with high count rates, large counter dynamics and very fast data readout. Data are readout in parallel by a PCI Express interface using DMA transfer. The readout frame rate of the complete detector comprising 0.5 MPixels amounts to 500 images per second without dead-time.

Do Extended Reality Interventions Benefit Patients Undergoing Elective Cardiac Surgical and Interventional Procedures? A Systematic Review and Meta‐analysis

open access: yesJournal of Clinical Nursing, Volume 34, Issue 4, Page 1465-1492, April 2025.
ABSTRACT Background Extended reality (XR) interventions have the potential to benefit patients undergoing elective cardiac surgical and interventional procedures. However, there are no systematic reviews with meta‐analyses to guide clinical care. Aim To critically evaluate the evidence on the effectiveness of XR interventions on patient anxiety and ...

Standardization via Post Column Infusion—A Novel and Convenient Quantification Approach for LC-MS/MS

open access: yesMolecules
Mass spectrometry (MS) is a widely used analytical technique including medical diagnostics, forensic toxicology, food and water analysis. The gold standard for quantifying compounds involves using stable isotope-labeled internal standards (SIL-IS ...

Regression-Based Proximal Causal Inference [PDF]

open access: yesarXiv
Negative controls are increasingly used to evaluate the presence of potential unmeasured confounding in observational studies. Beyond the use of negative controls to detect the presence of residual confounding, proximal causal inference (PCI) was recently proposed to de-bias confounded causal effect estimates, by leveraging a pair of treatment and ...

Contemporary Evidence, Treatment Strategies, and Indications for Chronic Total Occlusion-Percutaneous Coronary Intervention

open access: yesEuropean Medical Journal, 2017
Chronic total occlusions (CTOs) are detected incidentally in ˜20% of patients undergoing coronary angiography and are often associated with significant morbidity and mortality. CTOs can manifest with worsening symptoms, reduced left ventricular function,

Questões à "Interpretação da Consciência Processual" da Mecânica Quântica [PDF]

open access: yesarXiv
The processual consciousness interpretation (PCI), as developed in Arroyo (2024, chap. 5) and Arroyo, Nunes Filho, and Moreira dos Santos (2024), proposes a process ontology as a solution to the measurement problem. This article presents the standard interpretation taken to its ultimate ontological consequences; introduces the PCI; and offers ...

Inflammation and platelet reactivity during adjunctive colchicine versus aspirin in patients with acute coronary syndrome treated with potent P2Y12 inhibitor

open access: yesFrontiers in Medicine
BackgroundIn patients undergoing percutaneous coronary intervention (PCI), the use of anti-inflammatory therapy with colchicine is associated with a reduction of recurrent ischemic events.

Rethinking Programmed I/O for Fast Devices, Cheap Cores, and Coherent Interconnects [PDF]

open access: yesarXiv
Conventional wisdom holds that an efficient interface between an OS running on a CPU and a high-bandwidth I/O device should be based on Direct Memory Access (DMA), descriptor rings, and interrupts: DMA offloads transfers from the CPU, descriptor rings provide buffering and queuing, and interrupts facilitate asynchronous interaction between cores and ...

Regression-based proximal causal inference for right-censored time-to-event data [PDF]

open access: yesarXiv
Unmeasured confounding is one of the major concerns in causal inference from observational data. Proximal causal inference (PCI) is an emerging methodological framework to detect and potentially account for confounding bias by carefully leveraging a pair of negative control exposure (NCE) and outcome (NCO) variables, also known as treatment and outcome
