Soft Syndrome Decoding of Quantum LDPC Codes for Joint Correction of Data and Syndrome Errors [PDF]

arXiv, 2022
Quantum errors are primarily detected and corrected using the measurement of syndrome information which itself is an unreliable step in practical error correction implementations. Typically, such faulty or noisy syndrome measurements are modeled as a binary measurement outcome flipped with some probability.

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

Function and dysfunction of human sinoatrial node [PDF]

, 2015
Sinoatrial node (SAN) automaticity is jointly regulated by a voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release).

Post‐pacemaker implant QRS duration and heart failure admission in patients with sick sinus syndrome and complete atrioventricular block

ESC Heart Failure, 2019
High demand right ventricular pacing may elicit left ventricular systolic dysfunction known as pacing‐induced cardiomyopathy, increasing the risks of heart failure (HF) hospitalization.

The use of left ventricular ejection fraction in the diagnosis and management of heart failure. A clinical consensus statement of the Heart Failure Association (HFA) of the ESC, the Heart Failure Society of America (HFSA), and the Japanese Heart Failure Society (JHFS)

European Journal of Heart Failure, EarlyView.
Abstract This clinical consensus statement revisits the role of left ventricular ejection fraction (LVEF) as a measurement of cardiac function, a prognostic marker and a major criterion to classify patients with heart failure, and gives new advice for clinical practice.

The Role of the Calcium and the Voltage Clocks in Sinoatrial Node Dysfunction [PDF]

, 2011
Recent evidence indicates that the voltage clock (cyclic activation and deactivation of membrane ion channels) and Ca2+ clocks (rhythmic spontaneous sarcoplasmic reticulum Ca2+ release) jointly regulate sinoatrial node (SAN) automaticity.

Long‐term risk and characteristics of cerebrovascular events after upper body radiotherapy among childhood cancer survivors in the DCCSS‐LATER cohort

International Journal of Cancer, Volume 156, Issue 10, Page 1858-1872, 15 May 2025.
What's new? Due to the nature of cancer treatments, childhood cancer survivors have an increased risk of serious adverse events later in life. Here, the authors examined the incidence of cerebrovascular events (CVEs) among childhood cancer survivors who had received upper body radiotherapy.
