Loss of the cytochrome b6f subunit PetN destabilizes the complex and severely impairs state transitions in Anabaena variabilis.

The cytochrome b6f complex (Cyt b6f) plays pivotal roles in both linear and cyclic electron transport of oxygenic photosynthesis in plants and cyanobacteria. The four large subunits of Cyt b6f are responsible for organizing the electron transfer chain within Cyt b6f and have their counterparts in the cytochrome bc1 complex in other bacteria. The four small subunits of Cyt b6f are unique to oxygenic photosynthesis, and their functions remain to be elucidated.

Machine-learning heat flux closure for multi-moment fluid modeling of nonlinear Landau damping.

Nonlinear plasma physics problems are usually simulated through comprehensive modeling of phase space. The extreme computational cost of such simulations has motivated the development of multi-moment fluid models. However, a major challenge has been finding a suitable fluid closure for these fluid models.

TextIR: A Simple Framework for Text-based Editable Image Restoration.

Many current image restoration approaches utilize neural networks to acquire robust image-level priors from extensive datasets, aiming to reconstruct missing details. Nevertheless, these methods often falter with images that exhibit significant information gaps. While incorporating external priors or leveraging reference images can provide supplemental information, these strategies are limited in their practical scope.

An ultra-compact integrated phase shifter electrically tunable meta-waveguides.

Integrated photonics has emerged as a pivotal technology in the advancement of next-generation computing and communication devices. Thermal optical phase shifters (OPSs) have been widely used to realize a tunable Mach-Zehnder interferometer (MZI) and a micro-ring resonator (MRR), which are the building bricks for the LSI/VLSI photonic integrated circuits. Due to the thermal crosstalk and the low modulation efficiency, thermal OPSs have large-scale size and high power consumption.

Changes in Respiratory Sensitivity Status of Patients in a Hospital in Shanxi Province Before and After the COVID-19 Epidemic.

Background: The lifting of the regional blockade in early December 2022 in Shanxi Province, China, caused an epidemic of Coronavirus disease 2019 (COVID-19). And the high allergy season from July to September each year.

Purpose: To investigate the effect of the COVID-19 epidemic on the respiratory sensitivity status of the population, to provide a scientific and effective basis for the prevention, diagnosis, condition assessment, and treatment of allergic respiratory diseases.
