Article Synopsis
- This study aims to improve the speed of laparoscopic tool detection on embedded devices, which are portable and scalable but may have limited computing resources.
- The researchers modified the YOLOv7 model by halving its feature channels and integrating a new RepBlock, resulting in the YOLOv7-RepFPN model to reduce computational complexity.
- Experimental results showed that the YOLOv7-RepFPN achieved an mAP of 88.2% with 62.9 FPS for tool detection, outperforming the original YOLOv7 in speed while keeping accuracy nearly the same.

This study presents the first experimental evidence of direct H production from seawater without harmful gas emissions (, CO, Cl), which uses multiphoton ionization water splitting with a femtosecond pulse laser. According to H analysis using a gas chromatograph, the H production rate in seawater was 70 μmol h, which was approximately 3.3 times more than the ultrapure water case reported in the literature.

Structural Coupling of Extrinsic Proteins with the Oxygen-Evolving Center in Photosystem II.

Graduate School of Science, Nagoya University Aichi, Japan.
Photosystem II (PSII), which catalyzes photosynthetic water oxidation, is composed of more than 20 subunits, including membrane-intrinsic and -extrinsic proteins. The PSII extrinsic proteins shield the catalytic Mn4CaO5 cluster from the outside bulk solution and enhance binding of inorganic cofactors, such as Ca(2+) and Cl(-), in the oxygen-evolving center (OEC) of PSII. Among PSII extrinsic proteins, PsbO is commonly found in all oxygenic organisms, while PsbP and PsbQ are specific to higher plants and green algae, and PsbU, PsbV, CyanoQ, and CyanoP exist in cyanobacteria.
