Vortex-assisted photon counts and their magnetic field dependence in single-photon detectors

open access: yes, 2012
We argue that photon counts in a superconducting nanowire single-photon detector (SNSPD) are caused by the transition from a current-biased metastable superconducting state to the normal state. Such a transition is triggered by vortices crossing the thin

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Traveling wave method for simulating geometric beam coupling impedance of a beamscreen with pumping holes

open access: yes, 2019
In particle accelerators, pumping holes in a vacuum chamber can be a source of unwanted broadband coupling impedance, leading to beam instabilities. Analytical methods have been previously developed to estimate the impedance of holes in circular-like ...

Over‐Expression of a Phycocyanin‐Interferon Fusion and Differential Cleaving Efficiency in Cyanobacteria (Synechocystis sp. PCC 6803)

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Recombinant protein expression in heterologous biological systems is an expanding field in synthetic biology. Photosynthetic organisms have the potential to provide an efficient low‐cost platform for recombinant protein production because they require minimal growth nutrients and are less susceptible to zoonotic and other contaminants ...

Transparavertebral Occlusion of a Large Venovenous Collateral in a Fontan Patient

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Patients with a univentricular heart following completion of the Fontan circulation often experience varying degrees of desaturation due to the formation of venovenous collaterals. We present a rare case of a Fontan patient with an enlarged azygous vein shunting into the pulmonary venous system, causing significant desaturation. As no standard

Recanalization of Thrombosed Atrial Flow Regulator in Failing Fontan: A Bridge to Transplant

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 10‐year‐old boy (41 kg, 133 cm) with hypoplastic left heart syndrome (mitral and aortic atresia), who underwent staged palliation: Norwood‐Sano at 6 days, Glenn at 7 months, and Fontan completion at 3 years using a 16 mm non‐fenestrated extracardiac Gore‐Tex conduit.

Untargeted Metabolomics Identifies N‐Lactoyl‐Amino Acids as Dose‐Responsive Plasma Biomarkers of Metformin Adherence in Type 2 Diabetes

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Metformin is the most widely prescribed antidiabetic drug, yet adherence remains difficult to objectively assess. Using untargeted metabolomics and lipidomics, we analyzed plasma from 637 patients with type 2 diabetes (T2D) with confirmed metformin use and 143 nondiabetic controls, annotating 614 metabolites.

Interventional therapies for chronic heart failure: An overview of recent developments

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.
Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...
