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.

在分析了硅基上金属线圈的串联电阻、金属层厚度等在低频和高频的情况下对Q的影响及原因的基础上,提出了一种在硅杯表面采用浓硼扩散区与镀金属膜形成的欧姆接触电极作为内引线的硅基电感的新制造方法。设计了硅基电感的版图尺寸和相关的工艺流程,用IntelliSuite软件模拟验证了工艺流程的可能性,再利用Ansys有限元软件中的电磁分析模块模拟了电流与磁感应强度的关系、衬底涡流分布等,为平面电感的理论与实验的进一步比较分析提供了参考依据。在研制过程中发现影响电感性能好坏的主要因素是衬底涡流效应,为此提出了在矩形硅杯膜上制作电感的方法,为了进一步减薄金属电感线圈衬底的厚度,在硅杯膜背面采用激光打孔得到了膜厚约为5μm的衬底,从而可以使衬底中的涡流大幅度减少、电感的Q值得到很大提高。此外,提出的新制造方法采用了绝缘性能比SiO2好的Al2O3薄膜作为电感线圈与衬底之间的绝缘层。结果表明,设计的平面螺旋电感具有制造工艺简单、与IC工艺相兼容的优点,有广泛的应用前景。

Aiming at the high-dimensional uncertainties of restoration process, an optimization model for distribution system restoration control is proposed considering expected restoration benefits, expected restoration costs, and security risks of the overall restoration scheme. In the proposed model, the effect of security control on restoration process is actively analyzed considering the security control costs of preventive, emergency, and correction controls. A two-layer decision support framework for distribution system restoration decision support system(DRDSS) is also designed. The upper layer of the proposed framework generates the pre-adjustment schemes of operation mode for energized power grid by load transfer and selects the optimal pre-adjustment scheme and the corresponding partitioning scheme based on the partition adjustment results of each pre-adjustment scheme. In addition, it optimizes the spatial-temporal decision-making of the inter-partition connectivity. For each partition, the lower layer of the proposed framework pre-selects the units and loads to be restored according to the pre-evaluated restoration income, generates the table of alternative restoration scheme for coping with uncertain events through simulation and deduction, and evaluates the risk and benefit of each *** the uncertain events in the actual restoration process, the current restoration scheme can be adaptively switched to a sub-optimal scheme or re-optimized if necessary. Meanwhile, the proposed framework provides an information interaction interface for collaborative restoration with the related transmission system. A 123-node test system is built to evaluate the effectiveness and adaptability of the proposed model and framework.

The longitudinal wave propagating in one-dimensional periodic piezoelectric composite rod with inter-coupling between different piezoelectric segments is investigated. The analytical formulae for such a structure are shown and the dispersion relation is calculated. The results show that, by introducing the inter-coupling between the different piezoelectric segments, which is accomplished by serially connecting every n piezoelectric segment into supercells, some tunable Bragg band gaps can accordingly be opened in the low frequency region. The investigation could provide a new guideline for the tunable phononic crystal under passive control.
