Optics-free imaging of complex, non-sparse QR-codes with Deep Neural Networks [PDF]

arXiv, 2020
We demonstrate optics-free imaging of complex QR-codes using a bare image sensor and a trained artificial neural network (ANN). The ANN is trained to interpret the raw sensor data for human visualization. The image sensor is placed at a specified gap from the QR code. We studied the robustness of our approach by experimentally testing the output of the

Randomized QR with Column Pivoting [PDF]

, 2015
The dominant contribution to communication complexity in factorizing a matrix using QR with column pivoting is due to column-norm updates that are required to process pivot decisions. We use randomized sampling to approximate this process which dramatically reduces communication in column selection.

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management

Advanced Science, EarlyView.
Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

Electrocardiography in horses, part 2: how to read the equine ECG [PDF]

, 2010
The equine practitioner is faced with a wide variety of dysrhythmias, of which some are physiological. The recording of an exercise electrocardiogram (ECG) can help distinguish between physiological and pathological dysrhythmias, underlining the ...

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Comparison of the spatial QRS-T angle derived from digital ECGs recorded using conventional electrode placement with that derived from Mason-Likar electrode position [PDF]

, 2016
Background: The spatial QRS-T angle is ideally derived from orthogonal leads. We compared the spatial QRS-T angle derived from orthogonal leads reconstructed from digital 12-lead ECGs and from digital Holter ECGs recorded with the Mason-Likar (M-L ...

Pharmacokinetics of Ethyl Glucuronide and Ethyl Sulfate and Pharmacodynamic Effects Following Intravenous and Oral Administration of Ethanol to Exercised Horses

Drug Testing and Analysis, EarlyView.
This study describes the pharmacokinetics of ethanol metabolites following intravenous and oral administration to horses. Based on rapid metabolism, ethyl glucuronide is the best candidate for monitoring of illicit administration to performance horses.

A rare case of narrow QRS complex tachycardia [PDF]

Netherlands Heart Journal, 2014
The first ECG shows a regular narrow QRS complex tachycardia of approximately 160 beats/min. Clear P waves can be distinguished closely behind each QRS complex. These same P waves appear to be negatively deflected in the inferior leads, which could fit an atrioventricular (nodal) reentrant tachycardia (AVNRT) with retrograde P waves.
