Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...

, 2021 机械式撇油器是一种常用的海上溢油回收设备,为了提高其溢油回收效率,本文提出了一种基于表面漩涡和旋流分离技术的浓缩式漩涡撇油器。通过缩尺比1∶10的浓缩式漩涡撇油器测试样机,从造涡及溢油回收效果、波浪和运动对造涡影响、撇油器出口油相含率、撇油器溢流口压力变化规律和溢油回收效率等方面,测试并分析浓缩式漩涡撇油器的回收特性。同时耦合欧拉多相流模型和RSM湍流模型,求解并分析撇油器中旋流分离器内的油水两相旋流场特征。研究表明,浓缩式漩涡撇油器可抵御一定强度的波浪和撬体平移,有效形成表面漩涡和旋流器内旋流场 ...

Integrative Conservation, Volume 5, Issue 2, Page 192-204, June 2026.We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 756-763, June 2026.ABSTRACT Objectives Cytomegalovirus (CMV) is the leading cause of congenital infectious neurosensory impairment. We aimed to present national epidemiological data on maternal CMV infection during pregnancy in France, focusing in particular on primary infection in the periconceptional period or first trimester, and to assess the impact of changes in ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The large‐scale application of titanium is limited by its high production costs, as well as its low utilization and recycling rates. Therefore, efficient recovery of titanium scrap offers a viable pathway to reduce its cost. Molten‐salt electrolysis offers a promising route for upcycling titanium scrap, but the conventional method, which ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.
