The physical process of forming a modified region in soda-lime glass was investigated using 1 kHz intense femtosecond laser pulses from a Ti： sapphire laser at 775 nm. Through the modifications in- duced by the femtosecond laser radiation using selective chemical etching techniques, we fabricated reproducible and defined microstructures and further studied their morphologies and etching prop- erties. Moreover, a possible physical mechanism for the femtosecond laser modification in soda-lime glass was proposed.

Skeletal muscle plays a significant role in both local and systemic energy metabolism. The current investigation aims to explore the role of the Bambi gene in skeletal muscle, focusing on its implications for muscle hypertrophy and systemic metabolism. We hypothesize that skeletal muscle-specific deletion of Bambi induces muscle hypertrophy, improves metabolic performance, and activates thermogenic adipocytes via the reprogramming of progenitor of i WAT, offering potential therapeutic strategies for metabolic syndromes. Leveraging the Chromatin immunoprecipitation(ChIP)-seq and bioinformatics analysis, Bambi gene is shown to be a direct target of HIF2α, which is further confirmed by ChIP-qPCR and promoter luciferase assay. Skeletal muscle-specific Bambi deletion led to significant muscle hypertrophy and improved metabolic parameters, even under high-fat diet conditions. This deletion induced metabolic reprogramming of stromal vascular fractions(SVFs) into thermogenic adipocytes, contributing to systemic metabolic improvements, potentially through the secretory ***, mice with skeletal muscle-specific Bambi deletion demonstrate resistance to high-fat diet-induced metabolic disorders, highlighting a potential therapeutic pathway for metabolic syndrome management. Thus, skeletal muscle-specific deletion of Bambi triggers muscle growth, enhances metabolic performance, and activates thermogenic adipocytes. These findings suggest Bambi as a novel therapeutic target for metabolic syndromes, providing new insights into the interaction between muscle hypertrophy and systemic metabolic improvement. The study underscores the potential of manipulating muscle physiology to regulate whole-body metabolism, offering a novel perspective on treating metabolic disorders.

A rack cooling system based on a large scale flat plate pulsating heat pipe is proposed. The heat generated from IT equipment in a closed rack is transferred by the rear door pulsating heat pipe to the chilled air passage and is avoided to release into the room. The influence of the start-up performance of the heat pipe, the load of the rack and the load dissipation to the temperature and the velocity distribution in the rack are discussed. It is found that the temperature would be lower and the temperature distribution would be more uniform in the rack when the pulsating heat pipe is in operation. Also, the effect of rack electricity load on temperature distribution is analyzed. It is indicated that higher velocity of chilled air will improve heat transfer of the rack.
