Duchenne muscular dystrophy(DMD)is a severe neuromuscular disorder caused by mutations in the dystrophin gene,which encodes the essential protein *** genetic condition,affecting approximately 1 in 5000 male births worldwide(Birnkrant et al.,2018),is characterized by progressive muscle weakness and wasting,leading to premature death in the second or third decade of life(Farini et al.,2016).The absence of dystrophin protein causes instability in the sarcolemma,which predisposes individuals to myonecrosis and activation of inflammatory signaling ***,there is currently no effective cure for DMD,and glucocorticoid steroids are commonly used in clinical settings to delay symptom development(Merlini et al.,2003).

As an effective strategy to improve the properties of electrocatalysts,magnetic field-assisted electrocatalytic water splitting has attracted increasing attention ***,the corresponding enhancements mostly depend on the exertion of an external magnetic field during electrochemical reactions,which results in a high cost of industrial production,and makes the magnetic field manipulation of electrocatalysis become a challenging *** this work,instead of the external magnetic field,a bias magnetic field is self-supplied by the remanence state of a ferromagnetic electrocatalyst of *** to the assistance of this bias magnetic field,the FePt film in the remanence state shows the overpotential of 229 mV during hydrogen evolution reaction,which is much lower than that in its demagnetization state(283 mV).Our findings demonstrate that the remanence in ferromagnetic electrocatalysts can improve the catalytic performance,which is attributed to the decrease in domain walls.

通过理论分析与数值模拟相结合的方法,分析了双结构面对岩体强度的影响.研究表明,影响结构面滑移变形的主要因素有应力集中系数、采深、结构面倾角和结构面的力学参数.在结构面力学参数一定的情况下,应力集中系数越大及采深越大,结构面产生滑移变形的可能性越大;结构面倾角越小,产生滑移变形的可能性越大.采空区上部小角度结构面产生滑移变形是导致离层、产生底鼓的机制之一;两个弱面之间相互干扰、叠加影响了岩体的抗压强度,当两个弱面中有任一个弱面与轴线成30°时岩体抗压强度最小.
