Room-Temperature CMOS Monolithic Resonant Triple-Band Terahertz Thermal Detector.

Multiband terahertz (THz) detectors show great application potential in imaging, spectroscopy, and sensing fields. Thermal detectors have become a promising choice because they could sense THz radiations on the whole spectrum. This paper demonstrates the operation principle, module designs with in-depth theoretical analysis, and experimental validation of a room-temperature CMOS monolithic resonant triple-band THz thermal detector. The detector, which consists of a compact triple-band octagonal ring antenna and a sensitive proportional to absolute temperature (PTAT) sensor, has virtues of room-temperature operation, low cost, easy integration, and mass production. Good experimental results are obtained at 0.91 THz, 2.58 THz, and 4.2 THz with maximum responsivities of 32.6 V/W, 43.2 V/W, and 40 V/W, respectively, as well as NEPs of 1.28 µW/Hz0.5, 2.19 µW/Hz0.5, and 2.37 µW/Hz0.5, respectively, providing great potential for multiband THz sensing and imaging systems.

A new approach of operating room management in a general public hospital with multiple wholly-owned campuses / 中华护理杂志

Objective To explore a new approach of operating room (OR) management to ensure quality of care for surgical patients in a general public hospital with wholly-owned campuses. Methods The three-grade manageri-al structure for operating room was established,unified quality management was conducted in three campuses. Uni-fied training system was established to ensure the same level of professional competence among nurses. Highly flex-ible human resources allocation plan was performed for better staff rotation arrangement. Depending on information integration system,operation schedules of surgeons at all campuses were taken into consideration. Through instruments linkage among campuses,cost control was accomplished via scientific performance allocation mechanism. Results There was no statistically significant difference both in nursing quality scores and work satisfaction level of sur-geons for OR nurses among three campuses (P>0.05). The acquisition cost of instruments was reduced by 1.7048 million Yuan. Conclusion The new approach of operating room management guaranteed the quality of nursing care for surgical patients in three campuses,saved labor and financial cost in OR.

[Hypoglycemic and hypolipidemic effects of quercetin and its glycosides].

Quercetin and its glycosides are important flavonols in traditional herbal drugs and plant-derived food, and they have diverse hiological activities such as antioxidant, anticarcinogenic, anti-inflammatory, hypoglycemic and hypolipidemic activities. Numerous studies have demonstrated that quercetin and its glycosides were effective in the prevention and treatment of non-infectious chronic disease such as diabetes, obesity, and hyperlipidemia. They can regulate glucose and lipid metaholism through different mechanisms. They can decrease blood glucose via protecting pancreatic/p cells or/and improving insulin sensitivity. Also, they have lipid-lowering effects, which may be the result of regulation of lipid catabolism or/and anabolism. Their distributions, as well as the hypoglycemic and hypolipidemic effects are reviewed in this paper. In addition, further bioactivities as well as their dose-activity relationship, structure-activity relationship, bioavailability, and future clinical application of quercetin and its glycosides are discussed and proposed.
