Large language models (LLMs) have revolutionized natural processing (NLP) tasks by achieving state-of-the-art performance across a range of benchmarks. Central to the success these is integration sophisticated architectural components aimed at improving training stability, convergence speed, and generalization capabilities. Among components, normalization operation, such as layer (LayerNorm), emerges pivotal technique, offering substantial benefits overall model performance. However,...
In the Cooling storage ring External-target Experiment (CEE) in heavy ion research facility Lanzhou (HIRFL), multigap resistive plate chambers (MRPCs) detectors are used for high-precision time-of-flight (TOF) measurement to identify scattered particles after beam hits target. Regarding external TOF (eTOF) and 2/3 internal (iTOF) detectors, a ~25-ps rms time precision is required readout electronics, whereas other 1/3 iTOF ~10-ps required. A electronics prototype was designed, including...

The aims studying high-density nuclear matter properties with collisions GeV energy regime. adopts a master-slave structure serial data transmission mode using optical fiber to deal multi subdetectors long-distance signal flow. logic, based on field programmable gate array (FPGA) technologies, can...
Posterior pilon fracture is a relatively common clinical involving the posterior articular surface of distal tibia. Currently, this form receiving increasing attention. The surgical approach and technique for treatment fractures are still controversial. purpose retrospective study was to compare imaging outcomes after with open fibula line (OFFL) versus traditional posterolateral (TPL).A analysis patients treated using between January 2015 March 2020. Thirty-one cases were included in group...
In the field of nuclear medical imaging, and particle physics electronics, precise time measurement is an important task. this paper, we focused on a real-time interpolated timing algorithm based waveform digitization, which can be integrated in field-programmable gate array (FPGA) device. The basic principle to calculate pulse peak point when crosses threshold. We analyzed factors that would influence precision, conducted simulations estimate effect. After implementing FPGA, tests were with...
The Large High Altitude Air Shower Observatory is in the R&D phase, which Water Cherenkov Detector Array an important part. signals of Photo-Multiplier Tubes would vary from single photo electron to 4000 electrons, and both high precision charge time measurement required.

Waveform digitization is an important research direction in high-energy physics experiments. Compared to analog-to-digital converter (ADC) solutions, switched capacitor arrays (SCAs) have the advantages of high sampling rate, low power consumption, and easy multichannel integration. However, dead time SCA a limitation for high-hit-rate applications. To reduce quantization contributed by on-chip Wilkinson ADC, strategy high-speed less-bit coarse counter combined with multiphase clock locking...
