Fluorescein Leakage within Recent Subretinal Hemorrhage in Pathologic Myopia: Suggestive of CNV? by Lan Mi, Chengguo Zuo, Xiongze Zhang, Bing Liu, Yuting Peng, Feng Wen

“…In these 3 cases, SD-OCT showed a focal rupture of the retinal pigment epithelium-Bruch’s membrane-choriocapillaris (RPE-BM-CC) complex and a columnar hyperreflective signal of blood originating from defects with a volcanic geyser-like appearance, and no exudative signs were detected. Notably, all ruptures of the RPE-BM-CC complex were located exactly at lacquer crack sites. …”

EXPERIMENTAL STUDY ON THE PLANE STRAIN DYNAMIC FRACTURE TOUGHNESS OF 20CRMNTI BASED ON IMPROVED HPB PLATFORM by SONG Kun, ZHANG XiaoDi, DING Jun, HUANG Xia, HE XiaoJin, WANG JiaBin, WANG LuSheng

“…To obtain the dynamic fracture toughness of 20 Cr Mn Ti,an impact loading test was conducted on three-point bending specimens with the improved Hopkinson pressure bar.Dynamic stress intensity factor was determined by the spring mass model.The onset time of crack initiation is experimentally detected using the strain gauge method.Dynamic fracture toughness of20 Cr Mn Ti with type I crack was obtained through the above experimental procedure.The geometrical dispersion distortion caused by lateral inertia effect is effectively inhibited by the wave shaping technique,to ensure the consistency of stress wave signal in measuring point and loading point is guaranteed.At the same time,the high-speed camera system was used to collect the image and the change of the surface strain field during the loading process was analyzed with GOM Correlate.The results show that samples before crack initiation has reached the dynamic strain balance,ensure the validity of the experiment.…”

Mutation effect of acoustic and electromagnetic emissions of hard rock impact failure by Yang Liu, Cai-Ping Lu, Heng Zhang

“…The following main conclusions were drawn: (1) the stress level, frequency of micro-cracks, and impact failure regularity of hard rocks can be revealed with electromagnetic emission and acoustic emission/microseismic parameters, respectively; (2) acoustic emission/microseismic event counts can directly reveal the cracks change in rocks, and the initiation, propagation, and coalescence of micro-cracks can be presented as first increase, followed by decrease in acoustic emission/microseismic event counts; (3) in most cases, only when stress suddenly decreases or the rock final collapses, acoustic emissions show obviously abnormal; and (4) acoustic emission/microseismic can be more effectively applied to warn rockburst danger. …”
