当外界扰动频率接近块系岩体的固有频率时,会出现准共振现象。这一现象导致岩块间的弱夹层应变急剧变化,从而加快弱夹层的动态损伤断裂。为了研究块系岩体准共振导致岩块间弱夹层的动态拉压损伤断裂规律,基于块系岩体模型,分析准共振状态下弱夹层的变形特征。结合岩石动态损伤断裂准则,对准共振状态下弱夹层的动态损伤断裂进行理论计算分析,进而研究动态破坏规律。通过数值模拟揭示了准共振状态下块系岩体中弱夹层的损伤演化特征。结果表明:当块系岩体发生准共振现象时,岩块间的相对位移急剧增加,使得弱夹层的应变和损伤程度明显增大;弱夹层的损伤程度在准共振频率下最高,同时受外部扰动力和弱夹层的刚度、黏性、厚度及岩块质量等系统参数的影响;块系岩体发生准共振时断裂应力增大,但从断裂到完全破坏的时间明显缩短,即残余承载能力大幅下降。该研究对认识块系岩体的动态断裂具有一定的参考价值。

Abn.rmal expression.of microRn.s is con.ected to brain.developmen. an. disease an. could provide n.vel biomarkers for the diagn.sis an. progn.sis of bipolar disorder. We performed a PubMed search for microRn. biomarkers in.bipolar disorder an. foun. 18 origin.l research articles on.studies performed with human.patien.s an. published from Jan.ary 2011 to Jun. 2023. These studies in.luded microRn. profilin. in.bloodan. brain.based materials. From the studies that had validated the prelimin.ry fin.in.s,poten.ial can.idate biomarkers for bipolar disorder in.adults could be miR-140-3p,-30d-5p,-330-5p,-378a-5p,-21-3p,-330-3p,-345-5p in.whole blood, miR-19b-3p,-1180-3p,-125a-5p, let-7e-5p in.blood plasma, an. miR-7-5p,-23b-5p,-142-3p,-221-5p,-370-3p in.the blood serum. Two of the studies had in.estigated the chan.es in.microRn. expression.of patien.s with bipolar disorder receivin. treatmen.. On. showed a sign.fican. in.rease in.plasma miR-134 compared to baselin. after 4 weeks of treatmen. which in.luded typical an.ipsychotics, atypical an.ipsychotics, an. ben.odiazepin.s. The other study had assessed the effects of prescribed medication. which in.luded n.urotran.mitter receptorsite bin.ers(drug class B) an. sedatives, hypn.tics, an.icon.ulsan.s, an. an.lgesics(drug class C) on.microRn. results.
