Systolic geometry of translation surfaces

, 2020
Let $S$ be a translation surface of genus $g > 1$ with $n$ cone points $(p_i)_{i=1,\ldots,n}$ with cone angle $2\pi \cdot (k_i+1)$ at $p_i$, where $k_i \in \mathbb{N}$. In this paper we investigate the systolic landscape of these translation surfaces for

Bioactive Magnesium Silicate Activating Myocardial Energy Metabolism For Infarcted Myocardium Repair

Exploration, EarlyView.
ABSTRACT The heart is a highly energy‐dependent organ, developing bioenergy‐activating biomaterials to activate myocardial adenosine triphosphate (ATP) production and restore dysregulated energy homeostasis is a promising solution for its functional recovery.

Subclinical cardiac alterations and cardiometabolic profile in adolescents with newly diagnosed polycystic ovary syndrome: A cross‐sectional comparative echocardiographic study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective While cardiometabolic comorbidities have been well established in adults with polycystic ovary syndrome (PCOS), it remains unclear whether the early signs of cardiovascular morbidity emerge during adolescence. This study aimed to investigate whether metabolic and cardiovascular alterations begin in adolescents with PCOS.

Asymptomatic Giant Right Ventricular Myxoma in an Adolescent: A Rare Case Report With Favorable Surgical Outcome

Journal of Clinical Ultrasound, EarlyView.
We report a 13‐year‐old female with a giant right ventricular myxoma extending to the pulmonary trunk. The tumor was diagnosed by multimodal imaging and completely resected, with favorable short‐term outcomes. ABSTRACT Right ventricular (RV) myxomas account for < 5% of cardiac myxomas and are often asymptomatic, easily overlooked.

Comparative diagnostic accuracy study of point of care ultrasound techniques for detection of left atrial enlargement by hospital medicine physicians from archived echocardiogram images

Journal of Hospital Medicine, EarlyView.
Abstract Background Left atrial enlargement (LAE) is predictive of cardiovascular morbidity and mortality. Prior studies of point‐of‐care ultrasound (POCUS) interpretation methods for identifying LAE utilized older echocardiographic reference ranges. Objectives Compare the test characteristics of hospitalist‐performed POCUS techniques for identifying ...

Ferumoxytol-Enhanced Myocardial T1 Tracking Using a Hybrid 2D/3D Steady-State MRI Sequence Captures Cyclic Intramyocardial Blood Volume Dynamics. [PDF]

NMR Biomed
Cyclic changes in intramyocardial blood volume (iMBV) from systole to diastole can mark coronary disease without the need for vasodilator stress. We present a ferumoxytol‐enhanced MRI technique using a new continuous pulse sequence that effectively tracks cyclic myocardial T1 changes.

Systolic trees and systolic language recognition by tree automata

Theoretical Computer Science, 1983
AbstractRecently K. Culik II, J. Gruska, A. Salomaa and D. Wood have studied the language recognition capabilities of certain types of systolically operating networks of processors. Here their model for systolic VLSI trees is formalized in terms of standard tree automaton theory, and we show how some known facts about recognizable forests and tree ...
