Abstract: A joining element and joining method thereof are provided. The joining element comprises a head section, a rib section, and a tip section, wherein each cross section of the tip section has a geometric shape, and the geometric shape is formed by overlapping a plurality of ellipses. When the joining element applies downward pressure and rotational force on an assembly component, an inner concave portion of the geometric shape generates more plastic deformation heat than fraction heat on the material of the joining element. It facilitates the softening of the material in the assembly component, allowing for greater plastic deformation and, in turn, improves the assembly efficiency.

Abstract: This invention relates to the field of genetic molecular breeding, specifically to a pig 50K liquid-phase chip based on multiple single nucleotide-polymorphism and its application. The probe design of the chip in this invention takes into account the distribution of captured SNP loci across the genome, the polymorphism of the loci, the quality of mSNP markers, and other issues, effectively avoiding problems such as uneven marker density and poor polymorphism. It also considers the quality of mSNP markers and the issue of linkage disequilibrium among mSNP markers. While adhering to the basic principles of liquid-phase chip design, genomic regions with moderate linkage disequilibrium between markers were selected, generating more SNP markers with high genotyping quality and moderate linkage disequilibrium within the probe region with the target loci. The mSNP liquid-phase chip of this invention expands the detectable number of SNPs to 1.

Abstract: This invention relates to the field of genetic molecular breeding, specifically to a pig 10K liquid-phase chip based on multiple single nucleotide-polymorphism and its application. The present invention, while adhering to the basic principles of liquid phase chip design, adds new markers to existing chips and optimizes probes using multiple single nucleotide-polymorphism technology. This results in the generation of more SNP markers with high genotyping quality and moderate linkage disequilibrium with target SNP loci within the probe region, thereby increasing the effective marker count of the chip. The mSNP liquid phase chip of the present invention increases the number of detectable SNPs to 1.5-2 times the number of target SNP markers, addressing the issue of existing chips that only contain target SNPs and cannot provide mSNP markers, without increasing the cost.

Abstract: The described technology is generally directed towards scheduling, by a distributed unit, the injection of custom traffic (signals/data) into a radio unit communications path. The distributed unit coordinates with the radio unit to schedule and synchronize such custom traffic in unscheduled (physical resource block), such as interleaved with to live-air and non-live-air traffic. The radio unit can request the unscheduled physical resource blocks for custom traffic to be inserted by the radio unit. Alternatively, the distributed unit can inject the custom traffic in otherwise unscheduled physical resource blocks for sending to the radio unit. The custom traffic is configured to perform some action by the radio unit, such as to perform antenna calibration, to perform test and measurement operations to obtain performance data, and the like. Performance data can be used, for example, to modify operating parameters of the radio unit to improve performance of the radio unit.

Abstract: A computer-implemented method, according to one approach, includes: detecting new data generated at a first edge node, and causing a first copy of the new data to be transferred to a central data storage location in real-time. A second copy of the new data is also stored in a first location at the first edge node. In response to a predetermined condition being met, a determination is made as to whether any information in the first copy of the new data transferred is missing at the central data storage location. The first copy of the new data is removed from the first location at the first edge node in response to determining that no information in the first copy of the new data transferred is missing at the central data storage location.
