In this report, the impact of different mesa designs on optical and electrical characteristics for GaN-based micro-light emitting diodes (µLEDs) has been systematically numerically investigated by using TCAD simulation tools. Our results show that an enhanced light extraction efficiency can be obtained beveled mesas. The inclined angles more effectively reflect photons to substrate, helps extract free air flip-chip µLEDs. However, it is found current injection influenced inclination µLEDs,...
With an increasing amount of small nodules being detected, segmentectomy has recently received a great deal attention. We have previously reported the feasibility and safety uniportal segmentectomy. This study aims to further compare perioperative oncological outcomes three-port thoracoscopic in lung cancer patients.Patients undergoing for from January 2014 March 2021 were enrolled. Clinical data collected Western China Lung Cancer Database, prospectively maintained database at Department...
In this work, the scattering mechanism by nano-patterned sapphire substrate (NPSS) for flip-chip AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs) has been investigated systematically via three-dimensional finite-difference time-domain (3D FDTD) method. It is found that conventional DUV LED with a thick p-GaN layer, NPSS structure can enhance light extraction efficiency (LEE) transverse magnetic (TM)-polarized because TM-polarized large incident angles be scattered into escape...
Due to the increased surface-to-volume ratio, surface recombination caused by sidewall defects is a key obstacle that limits external quantum efficiency (EQE) for GaN-based micro-light-emitting diodes (µLEDs). In this work, we propose selectively removing periphery p + -GaN layer so an artificially formed resistive ITO/p-GaN junction can be at mesa edge. Three types of LEDs with different device dimensions 30 × µm 2 , 60 and 100 are investigated, respectively. We find such effectively...
In this work, unique properties and tremendous advantages for an omni-directional reflector (ODR) on inclined sidewall flip-chip AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs) are systematically investigated via a three-dimensional finite-difference time-domain method. It is found that although the reflectivity of Ag far lower than Al, light extraction efficiency DUV LED with Ag-based ODR not always Al-based one within certain incident angles. The reason total internal...

The availability and affordability of medicines remain major health challenges around the world. In March 2019, Chinese government introduced a pilot National Centralized Drug Procurement (NCDP) program in order to reduce drug prices improve effective safe medicines. This study aimed assess impact NCDP policy on expenditures cancer patients. Using inpatient discharge records from large hospital city, we performed difference-in-differences design estimate change before after policy. We found...
In this report, we propose GaN-based vertical cavity surface emitting lasers with a p-GaN/n-GaN/p-GaN (PNP-GaN) structured current spreading layer. The PNP-GaN layer can generate the energy band barrier in valence because of modulated doping type, which is able to favor into aperture. By using layer, thickness for optically absorptive ITO be reduced decrease internal loss and then enhance lasing power. Furthermore, investigate impact concentration, position inserted n-GaN on lateral hole...
The hole injection capability is essentially important for GaN-based vertical cavity surface emitting lasers (VCSELs) to enhance the laser power. In this work, we propose VCSELs with p-AlGaN/p-GaN structure as p-type supplier facilitate injection. heterojunction able store electric field and thus can moderately adjust drift velocity kinetic energy holes, which improve thermionic emission process holes travel across electron blocking layer (p-EBL). Besides, valence band barrier height in...
Adenosquamous carcinoma is a rare subtype of non-small cell lung cancer characterized by aggressive behavior, with combination adenocarcinoma and squamous components. The clinicopathological characteristics prognosis resectable adenosquamous are incompletely understood this study aimed to depict those in large population.A total 805 carcinoma, 7875 23 957 patients who underwent lobectomy or sublobectomy were queried from the Surveillance, Epidemiology, End Results database (2010-17)....
Background Uniportal video-assisted thoracoscopic surgery (UniVATS) was utilized with a rapid growth. The evidence is sparse, however, on whether to add external suction water-seal drainage for chest after UniVATS. This retrospective propensity score-matched study aimed identify the necessity of adding Methods Patients lung cancer who underwent UniVATS were included from our prospectively maintained database. divided into two cohorts based addition postoperative or not. Propensity analysis...
Abstract Background The association between adult body mass index (BMI) and lung cancer (LC) susceptibility have been reported, but the causal relationship with childhood BMI remains largely unclear. To evaluate effect of on LC susceptibility, a two‐sample Mendelian randomization (MR) study was performed. Methods MR analysis utilized 25 single nucleotide polymorphisms (SNPs) as instrumental variables for BMI. Genetic summary data from International Lung Cancer Consortium FinnGen databases...
