Dual-mode operation of GaN-based p-i-n diodes for electroluminescent emission and self-powered photodetection.

The integration of light-emitting displays and photodetectors into a single device is increasingly attractive for the development of multifunctional and energy-efficient systems. In this study, we present a gallium nitride (GaN) based photodetection light-emitting diode (pdLED) capable of dual-mode operation through simple bias control. Under forward bias, the pdLED functions as an efficient light emitter, achieving a peak external quantum efficiency (EQE) and a wall plug efficiency (WPE) of 21.

Short time effects of two radiofrequency ablation methods on hypertrophic obstructive cardiomyopathy.

Background: Radiofrequency ablation has been applied for the treatment of hypertrophic obstructive cardiomyopathy (HOCM). The two known procedures are percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) and endocardial radiofrequency septal ablation (ERSA).

Methods: This study presents a retrospective analysis of the PIMSRA and ERSA procedures in patients with drug-refractory HOCM.

Validity and Psychometric Evaluation of the Chinese Version of the 5-Item WHO Well-Being Index.

Aims: This article evaluates the psychometric properties of the Chinese version of the 5-item WHO Well-Being Index (WHO-5) in mainland China.

Methods: Two cross-sectional studies with 1,414 participants from a university in China were conducted. The Chinese version of the WHO-5 was assessed to determine its internal consistency, concurrent validity, factorial validity, and construct validity.

Quantum transport of short-gate MOSFETs based on monolayer MoSiN.

The high carrier mobility, appropriate band gap and good environmental stability of two-dimensional (2D) MoSiN enable it to be an appropriate channel material for transistors with excellent performance. Therefore, we predict the performance of double-gate (DG) metal-oxide-semiconductor field-effect transistors (MOSFETs) based on monolayer (ML) MoSiN by quantum-transport calculations. The results show that the on-state current of the p-type device is remarkable when the gate length is greater than 4 nm, which can meet the high performance requirements of the International Technology Roadmap for Semiconductors (ITRS), 2013 version.

Evaluation of the automated ADVIA centaur® XP syphilis assay for serological testing.

We evaluated the performance of the ADVIA Centaur XP Syphilis assay (Siemens Healthcare Diagnostics, Tarrytown, NY, USA) using samples previously tested on the ARCHITECT i4000SR system (Abbott Diagnostics, Lake Forest, IL, USA) and confirmed by the Treponema pallidum particle agglutination assay (TPPA) (SERODIA-TPPA, Fujirebio Diagnostics Inc., Malvern, PA, USA). Clinical patient information was included to aid resolution of discordant samples where available.

Advantages and disadvantages of F-18 fluorodeoxyglucose positron emission tomography/computed tomography in carcinoma of unknown primary.

Carcinoma of unknown primary is a type of malignant disease where the primary carcinoma cannot be identified by conventional examination, which presents challenges in diagnosis and therapy. This study aims to evaluate the detailed clinical value and indications of using fluorine-18-2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (F-18 FDG PET/CT) in a large sample. A total of 449 patients who were selected under strict standards were retrospectively included in this study.

Inhibition of influenza virus infection with chitosan-sialyloligosaccharides ionic complex.

With the recent emergence of drug-resistant influenza viruses, effective means of preventing and treating these contagious pathogens have become imperative. The binding receptors of influenza virus are sialyloligosaccharides (SOS), which are present on the surfaces of host cells, and are therefore attractive targets for antiviral development. We report the preparation and identification of a novel influenza virus entry inhibitor, designated chitosan-SOS complex (CS complex).

[Analytical method and comparison for static and dynamic headspace gas chromatography of anisole in water].

Objective: To establish and compare the method of static headspace gas chromatography hydrogen flame detector (static headspace method) and purge and trap gas chromatography-mass spectrometry (dynamic headspace method) of anisole in water.

Methods: Nitrogen gas was used as carrier gas in the static headspace method, 5 g NaCl as matrix modifier was added into 10 ml water. The sample was balanced with high speed vibration at 75°C for 30 min, and anisole was detected by gas chromatography and quantified with external standard.
