Measuring brain beats: Cardiac‐aligned fast functional magnetic resonance imaging signals
Human Brain Mapping, Volume 44, Issue 1, Page 280-294, January 2023., 2023 Blood and cerebrospinal fluid (CSF) pulse and flow throughout the brain, driven by the cardiac cycle. We use rapid functional magnetic resonance imaging (fMRI) measurements to assess blood and CSF flow dynamics in a conventional 3 T magnetic resonance imaging scanner.

Journal of Clinical Ultrasound, Volume 51, Issue 1, Page 31-35, January 2023., 2023 This study aimed to examine the association between catecholamines and echocardiographic parameters indicative of cardiac damage in patients with PPGL. The conclusion is that catecholamine effects on the myocardium are reflected in echocardiographic diastolic function parameters.

Relative systoles of relative-essential 2-complexes [PDF]
, 2010 We prove a systolic inequality for the phi-relative 1-systole of a phi-essential 2-complex, where phi is a homomorphism from the fundamental group of the complex, to a finitely presented group G.

Automatic Time‐Resolved Cardiovascular Segmentation of 4D Flow MRI Using Deep Learning
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 191-203, January 2023., 2023 Background Segmenting the whole heart over the cardiac cycle in 4D flow MRI is a challenging and time‐consuming process, as there is considerable motion and limited contrast between blood and tissue. Purpose To develop and evaluate a deep learning‐based segmentation method to automatically segment the cardiac chambers and great thoracic vessels from 4D

Systoles and kissing numbers of finite area hyperbolic surfaces [PDF]
, 2015 We study the number and the length of systoles on complete finite area orientable hyperbolic surfaces. In particular, we prove upper bounds on the number of systoles that a surface can have (the so-called kissing number for hyperbolic surfaces). Our main
