A p-type polycrystalline silicon thin-film transistor (TFT) was fabricated using the metal-induced lateral crystallization (MILC) technique at 550 degrees C. To reduce the leakage current in the MILC TFT, electrical stress (ES), newly developed in this work, was applied prior to the I(D)-V(G) measurements. It was found that ES is effective only when the TFT is under off-state. The stress gate voltage is related to the leakage current at high gate voltages and the electric field between the source and the drain to the leakage current at low gate voltages. The leakage current of the MILC TFT could be lowered to 10(-11) A for width/length ratios of 1/2 measured at the drain voltage of 3 V. A new plausible model has been suggested to explain the ES effect on the leakage current behavior in low-temperature polycrystalline silicon TFTs.

The effective prevention and treatment of anastomotic leakage after intestinal anastomosis for colorectal diseases is still a major clinical challenge. In order to assist intestinal anastomosis healing and avoid anastomotic leakage caused by high tension, low blood supply or infection, we designed a double-layer nanofiber intestinal anastomosis scaffold, which was composed of electrospun PTMC/PHA nanofibers as the main layer, and electrospun PVA/OHA-Gs nanofibers with antibacterial properties as the antibacterial surface layer. This double-layer scaffold has good toughness, its maximum tensile force value could reach 8 N, elongation could reach 400 %, and it has hydrophilic properties, and its contact angle was about 60°.

Maternal immune activation (MIA), a maternal stressor, increases risk for neuropsychiatric diseases, such as Major Depressive Disorder in offspring. MIA of toll-like receptor 7 (TLR7) initiates an immune response in mother and fetuses in a sex-selective manner. The paraventricular nucleus of the hypothalamus (PVN), a brain region that is sexually dimorphic and regulates hypothalamic-pituitary-adrenal (HPA) stress responses, have been tied to stress-related behaviors (i.

GaN is rapidly gaining attention for implementation in power electronics but is still impacted by its high density of threading dislocations (TDs), which have been shown to facilitate current leakage through devices limiting their performance and reliability. Here, we discuss a novel implementation of photoluminescence (PL) imaging to study TDs in regions within vertically structured p-i-n GaN (PIN) diodes consisting of metalorganic chemical vapor deposition (MOCVD) epitaxial layers grown on ammonothermal GaN (am-GaN) substrates. PL imaging with a sub-bandgap excitation energy (3.

Introduction: Preoperative identification of the site of rectal cancer surgery is crucial for ensuring accurate tumor localization and resection. Commonly employed methods include contrast-enhanced enterography and endoscopic marking techniques, such as clipping and India ink tattooing. However, India ink tattooing poses challenges, including obstruction of the surgical field, ink leakage into the abdominal cavity, and potential complications such as peritonitis and adhesive bowel obstruction.
