Kinetic Inductance of Josephson Junction Arrays: Dynamic and Equilibrium Calculations

, 1994
We show analytically that the inverse kinetic inductance $L^{-1}$ of an overdamped junction array at low frequencies is proportional to the admittance of an inhomogeneous equivalent impedance network.

A Comparative Study of Ultrasonography and CT Venography in the Diagnosis of Budd‐Chiari Syndrome

Journal of Clinical Ultrasound, EarlyView.
Budd‐Chiari syndrome (BCS) is characterized by hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. Ultrasound (US) and CT venography (CTV) are used as imaging techniques for the diagnosis of BCS, and We compared the diagnostic efficacy of the two modalities. The results showed that

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Pre‐ and Post‐Interventional Hemodynamic Characterization of the Femoropopliteal Artery Using Vector Flow Imaging in Peripheral Arterial Occlusive Disease

Journal of Ultrasound in Medicine, EarlyView.
Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

Clinical and Radiological Evolution of Idiopathic Normal Pressure Hydrocephalus: A Critical Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background The pathophysiology of idiopathic normal pressure hydrocephalus (iNPH) remains poorly understood. While it is commonly accepted that iNPH has an insidious onset, little is known about its preclinical and early stages and its development over time.

Neonatal Arnold-Chiari II Malformation: An Imaging-Focused Case Report. [PDF]

Clin Case Rep
ABSTRACT Arnold‐Chiari Malformation Type II (CM‐II) is a serious congenital hindbrain disorder marked by the displacement of the cerebellum and brainstem downwards through the foramen magnum. CM‐II is frequently linked with myelomeningocele and hydrocephalus.

Human CNTNAP1 Variants Associated With Severe Neurological Deficits: Additional Cases and Literature Review

Muscle &Nerve, EarlyView.
ABSTRACT CNTNAP1 encodes the Contactin‐Associated Protein 1 (CNTNAP1), also known as Caspr1, which is a transmembrane protein critical for nervous system function. CNTNAP1 is localized to the paranodal regions of all myelinated axons, flanking either side of the node of Ranvier.

Lymphatic topology reveals a novel intranodal lympho‐venous shunt

The Journal of Pathology, EarlyView.
Abstract Understanding the lymphatic network is crucial for immunological research. Currently, a complete map of lymphatic drainage in mice is lacking. We present a detailed lymphatic system flow dynamic of two mouse strains with swollen lymph nodes (LNs), using region‐specific tracer injection and high‐resolution micro‐CT imaging to characterize LN ...
