Annular cavity VCSELs: enhanced beam quality and speckle-less illumination.

Vertical-cavity surface-emitting lasers (VCSELs) are valued for their high coupling efficiency, directionality, and low cost. Broad-area (BA)-VCSEL, in particular, offers the possibility of a customizable degree of spatial coherence and high output power for low-speckle imaging, illumination, communication, and augmented reality technologies. However, new designs of BA-VCSEL for scalable fabrication need to be developed.

Micro-LED-based quantum random number generators.

Quantum random number generators (QRNGs) leverage the inherent unpredictability of quantum mechanical phenomena to produce random numbers. However, the performance of many QRNGs is hindered by limitations such as low generation rates and the bulkiness of systems utilizing single-photon detectors (SPDs). In this study, we present a QRNG that addresses these challenges by using a micro-LED as an entropy source, utilizing the intensity fluctuations of spontaneous emissions.

Loss-of-function of sox3 causes follicle development retardation and reduces fecundity in zebrafish.

Folliculogenesis is essential for production of female gametes in vertebrates. However, the molecular mechanisms underlying follicle development, particularly apoptosis regulation in ovary, remain elusive. Here, we generated sox3 knockout zebrafish lines using CRISPR/Cas9.

RAB37 interacts directly with ATG5 and promotes autophagosome formation via regulating ATG5-12-16 complex assembly.

Intracellular membrane trafficking is essential for eukaryotic cell existence. Here, we show that RAB37 activation through GTP binding recruits ATG5-12 to isolation membrane and promotes autophagosome formation through the ATG5-ATG12-ATG16L1 complex. RAB37 is localized on the isolation membrane.

[Introduction and selection of new poplar clones in shelterbelts/windbreaks in northern Liaoning].

Six new poplar clones were introduced in Qianshuanging township of Changtu county, Liaoning Province as experiment materials, and their indeces in growth, cold resistance, disease infection, and insect infection were evaluated and compared to the locally grown Fuzha II poplar. According to the comparison of the 4 indices, the study found that N-119 poplar showed all the scores obviously better than those of CK and other poplars, and was recommended for the area. The growth of Zhonglin 95 was higher, and its disease and pest infection was equal or near to the CK.

[Early diagnosis of low-value forest: an approach of ecological factors].

The management and improvement of low-value forests is an important issue of forestry in China. This paper put forward a new thought of early diagnosis for low-value forest. By applying this method, the forest growth trend before the explosion of the state of low-value forest was diagnosed according to the formation rule of low-value forest, and so, managers could adopt corresponding management measures in time.
