Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes
Advanced Materials Technologies, EarlyView.This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

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.

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 ...

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023 Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.
