title: Study on the Evolution Mechanism of molten pool surface morphology of Negative Pressure Arc welding via Fully Coupled Arc-Pool Free Surface Model
title: Study on the Evolution Mechanism of molten pool surface morphology of Negative Pressure Arc welding via Fully Coupled Arc-Pool Free Surface Model

description: The accuracy of thin-walled structures in arc additive manufacturing components is limited by the overflow of molten pool caused by positive pressure arc. Therefore, our team introduced negative pressure arc additive technology, but the research on the mechanism of molten pool movement under negative pressure arc has not been explored yet. Therefore, a fully coupled arc pool model containing free surface deformation is used to study the interactions between heat, force, flow, and free surface morphology under negative pressure conditions in the melt pool. The results indicate that negative pressure arc can effectively improve the depression of the molten pool. With the increase of welding current and magnetic field strength, the electromagnetic stirring force is enhanced, and the molten pool exhibits severe centrifugal phenomenon, leading to an increase in molten pool depression. Negative pressure arc achieves a more uniform distribution of heat input, forming a low-temperature zone in the center of the melt pool. Through the Marangoni effect, a counter current zone is generated, thereby reducing the flow velocity at the center of the molten pool. This study has made significant contributions to understanding the mechanism of molten pool under negative pressure and laid a theoretical foundation for the application of negative pressure arc addition technology.

title: Spatial transcriptomics data of mouse thymus
title: Spatial transcriptomics data of mouse thymus

description: The thymus is a critical organ for T cell development and immune system function, but it undergoes significant structural and functional changes during aging, a process known as thymic involution. To investigate the spatial and cellular changes associated with thymic aging, we performed single-cell spatial transcriptomics on thymic tissues from young (4-week-old) and aged (52-week-old) C57BL/6J mice, with three biological replicates per age group. This dataset provides a detailed spatial and cellular map of the thymus at single-cell resolution, capturing changes in cell types, abundances, and spatial organization during aging. The results offer valuable insights into the cellular and spatial heterogeneity of the thymus and provide a resource for understanding immune system aging and potential therapeutic strategies.

title: New measurement of Cu-63(γ, n)Cu-62 cross section using quasi-monoenergetic γ-ray beam
title: New measurement of Cu-63(γ, n)Cu-62 cross section using quasi-monoenergetic γ-ray beam

description: We present new data on the 63Cu(γ, n) cross section studied using a quasi-monochromatic and energy-tunable γ beam produced at the Shanghai Laser Electron Gamma Source to resolve the long-standing discrepancy between existing measurements and evaluations of this cross section. Using an unfolding iteration method, 63Cu(γ, n) data were obtained with an uncertainty of less than 4%, and the inconsistencies between the available experimental data were discussed. The γ-ray strength function of 63Cu(γ, n) was successfully extracted as an experimental constraint. We further calculated the cross-section of the radiative neutron capture reaction 62Cu(n, γ) using the TALYS code. Our calculation method enables the extraction of (n, γ) cross sections for unstable nuclides.

title: Golden pheasant diploid genome
title: Golden pheasant diploid genome

description: Avian genomes are characterized by streamlined organization and stable chromosomes. Whether and how the patterns of structural variation of avian genomes are different from other vertebrate lineages is poorly explored. Here, we generated a diploid genome assembly for the golden pheasant (Chrysolophus pictus), a bird with gorgeous plumage in males. Each haploid genome assembly contains complete chromosomal models, including all microchromosomes. We discovered tandem amplification of immune genes across the smallest microchromosomes (dot chromosomes), with an average copy number of 54. We further discovered that the landscape of structural variation between the two haploid genomes is primarily shaped by large indels, with little impact from inversions or duplications. About ~28% of the large indels are associated with recent insertions of transposable elements whose activities are usually infrequent in bird genomes. We however find little evidence for the role of transposable elements in altering gene expression. Finally, we identified evolutionary strata on the sex chromosomes and characterized the drastic rearrangement of the W chromosome. Our analyses on the high-quality diploid genome of golden pheasant provide insights into the evolutionary patterns of structural variation of avian genomes.

title: Status calibration of pulse shaping system for the high power laser facility based on deep learning

description: The characteristic differences between each facility make it necessary for researchers to use specific strategies in conjunction with the actual situation. The initial AWG electrical waveform of the pulse shaping closed-loop system of the SG Ⅱ series facility is obtained by inversion of the regenerative injection waveform[8], and the pulse waveform data with a repetition frequency of 1 Hz is easy to be collected, which facilitates the formation of a rich dataset. Therefore, we calculate the initial AWG electrical waveform in the pulse shaping closed-loop control system using a deep learning model, which is based on the front-end injection system of the SG-Ⅱ series facility.

title: Effective sensitization of Dy3+:6H11/2 energy level by Tm3+ ions in KPb2Br5 crystal for 4.3 µm lasers
title: Effective sensitization of Dy3+:6H11/2 energy level by Tm3+ ions in KPb2Br5 crystal for 4.3 µm lasers

description: To the best of our knowledge, this is the first study to investigate the use of Tm3+ to sensitize the Dy3+ ion and enhance the ∼4.3 µm emission from Dy3+:6H11/2 → 6H13/2 in the KPb2Br5 (KPB) crystal. The ∼4.3 µm fluorescence emission properties and energy transfer mechanism of the Dy:KPB and Tm,Dy:KPB crystals were examined. The results show that Tm3+ is an excellent sensitizer to the Dy3+ ion and can provide an efficient excitation channel; thus, the Tm,Dy:KPB crystal can be pumped by a commercial 808 nm laser diode (LD). Compared with the Dy:KPB crystal, co-doping with the Tm3+ ion improves the absorption around 800 nm by an order of magnitude, and the energy transfer efficiency from Tm3+:3F4 to Dy3+:6H11/2 is as high as 76.7%, indicating that the Tm,Dy:KPB crystal has great potential application in ∼4.3 µm mid-infrared lasers under a commercial LD pump
