title: Sub-kHz linewidth 1.6-μm single-frequency fiber laser based on heavily erbium doped silica fiber
title: Sub-kHz linewidth 1.6-μm single-frequency fiber laser based on heavily erbium doped silica fiber

description: We present a single-frequency erbium doped fiber laser operated at 1608.8 nm using a homemade, heavily erbium doped silica fiber as gain medium. The laser configuration is based on a ring cavity, which is combined with a fiber saturable absorber to achieve single-frequency operation. The measured laser linewidth is less than 447 Hz and optical signal-to-noise ratio exceeds 70 dB. The laser exhibited an excellent stability, without any instance of mode-hopping during 1 hour observing, and the fluctuations in both wavelength and power were measured to be 0.002 nm and less than 0.09 dB in a 45 minutes period. The laser produced over 14 mW of output power with a slope efficiency of 5.3%, to the best of our knowledge, this is currently the highest power directly obtained from a single-frequency cavity based on erbium doped silica fiber above 1.6 μm.

title: Mitofusin 2 Gene Polymorphisms and Metabolic dysfunction Associated Fatty Liver Disease: a case-control study in a Chinese population

description: A total of 889 subjects presenting at the physical examination center of Third Hospital of Hebei Medical University, Shijiazhuang, China was enrolled in the study. Demographic characteristics including age, gender, height, body weight and biochemical characteristics were collected. Six SNPs (rs2336384, rs873458, rs873457, rs4846085, rs2878677 and rs2236057) were selected based on the previous reports of variants associated with metabolic dysfunction. Rs2336384, rs873458, rs873457 and rs4846085 are located within intron 2; rs2878677 within intron 3 and rs2236057 within intron 11. Genomic DNAs were extracted from peripheral blood leukocytes using a genomic DNA kit (GENEray Biotechnology, Shanghai, China). Mfn2 gene polymorphisms were detected by the ligase detection reaction (LDR). Primer Premier 5.0 software (Premier Biosoft Intl., CA USA) was used to design primers for amplification based on Genbank reference sequence, NG_007945.1. Probes were designed based on GENEray Biotechnology. Genotypes were evaluated using DNA sequencing on an ABI 3730 genetic analyzer (Applied Biosystems, USA), in accordance with the manufacturer’s instructions, and sequenced with GeneMarker V2.2.0 (PA, USA).

title: Improved Radiation Resistance of Er-Yb Co-Doped Silica Fiber by Pretreating Fibers
title: Improved Radiation Resistance of Er-Yb Co-Doped Silica Fiber by Pretreating Fibers

description: In this study, a pretreatment method for improving the radiation resistance of Er-Yb co-doped silica fiber (EYDF) is proposed. EYDF is the object in this method and is processed by two steps, including deuterium loading and pre-irradiation. The effects of pretreatment conditions on the laser performance and radiation resistance of EYDF were systematically studied. An online irradiation experiment setup was utilized to evaluate the radiation resistance of EYDF. The results demonstrate that the pretreatment can significantly improve the radiation resistance of EYDF, with minimal impact on the laser output power and slope efficiency. Specifically, the radiation-induced gain variations in the pristine fiber and the pretreated fiber with a cumulative dose of 240 krad were 3.13 dB and 1.81 dB, respectively. Additionally, the high-vacuum experiments show that the proposed pretreatment method can maintain a long-term stable radiation resistance improvement in the fiber. This study provides a method to improve the radiation resistance of EYDF for space applications.

title: Chloroplast genome sequences and phylogenetic analysis of eight Caryophyllaceae species in the Qinghai-Tibet Plateau
title: Chloroplast genome sequences and phylogenetic analysis of eight Caryophyllaceae species in the Qinghai-Tibet Plateau

description: The eight cp genomes were 132,188-151,919 bp in length, containing 130-132 genes. A/T was dominant in SSRs. Forward repeats and palindromic repeats were the most frequent in long terminal repeats. Compared with the four species of the genus Eremogone, the IR boundary of S. caespitella, S. atsaensis, S. lhassana and Sh. glanduligera were significantly expanded. Six and one hotspots were identified in the LSC region and SSC region, respectively. The Ka/ks ratio showed these cp genomes may have undergone strong purifying selection. In the phylogenetic trees, our study was consistent with APG Ⅳ. The four species of the genus Eremogone were closer phylogenetically than to species of distinct genera. S. caespitella and S. atsaensis clustered together while S. lhassana was more closely to S. latifolia. In addition, Shivparvatia. glanduligera was close to the genus Pseudostellaria.

title: An Anatomical and Connectivity Atlas of the Marmoset Cerebellum
title: An Anatomical and Connectivity Atlas of the Marmoset Cerebellum

description: The cerebellum is a key region of the brain for motor control and cognitive functioning, and it is involved bidirectional communication with the cerebral cortex. As one of the smallest non-human primates, the common marmoset provides many advantages in the study of the anatomy and the functions of cerebello-cerebral circuits. However, the cerebellum of the marmoset is far from being well described in published resources. In this study, we present a comprehensive atlas of the marmoset cerebellum in three parts: 1) fine-detailed anatomical atlases and surface-analyzing tools of the cerebellar cortex, based on ultra-high resolution ex-vivo MRI; 2) functional-connectivity gradients of the cerebellar cortex, based on awake resting-state fMRI; and 3) structural-connectivity based mapping of the cerebellar nuclei, based on high-resolution diffusion tractography. The atlas shows the anatomical details of the marmoset cerebellum; reveals distinct gradient patterns of the intra-cerebellar and the cerebello-cerebral functional connectivity; and maps the topological relationship of the cerebellar nuclei in cerebello-cerebral circuits. As version 5 of the Marmoset Brain Mapping project, the atlas describes the anatomical and connectivity details of the marmoset cerebellum and is publicly available via marmosetbrainmapping.org/MBMv5.html.
