Visual impairments and blindness are major public health concerns globally. Effective eye disease screening aided by artificial intelligence (AI) is a promising countermeasure, although it challenged practical constraints such as poor image quality in community screening. The recently developed ophthalmic foundation model RETFound has shown higher accuracy retinal recognition tasks. This study an RETFound-enhanced deep learning (DL) for multiple-eye using real-world images from screenings....

Mutagenesis breeding, combined with the application of corresponding herbicides to develop herbicide-resistant rice germplasm, provides great promise for management weeds and weedy rice. In this study, a topramezone-resistant mutant, TZR1, was developed from indica line Chuangyu 9H (CY9H) through radiation mutagenesis topramezone selection. Dose–response curves revealed that resistance index TZR1 1.94-fold compared CY9H. The mechanism not due target-site resistance. This could be reversed by...

Abstract Rice, a major global food crop, faces considerable challenges from herbicide damage, particularly pre‐emergent herbicides like Pretilachlor (Pre). Herbicide‐resistant rice varieties and efficient, environmentally friendly safeners for Pre are still lacking. Substituted salicylic acid show the potential to relieve damage but limited by poor solubility penetration. This study explores novel substituted derivative salt, matrine (MT)‐3‐nitrosalicylic (3‐NO 2 SA) salt (MNS), as safener...

It has been assumed that functions as structural protein, although this not directly tested. Here vivo of are examined via generation mice with a targeted disruption Crybb2. methods. Gene targeting embryonic stem cells was used to generate mouse lines which Crybb2 deleted. structure and protein expression were analyzed by PCR, immunoblot, two-dimensional gel electrophoresis.

Abstract Episodic tremor and slip (ETS) in subduction zones is generally interpreted as the manifestation of shear near base earthquake‐generating portion plate interface. Here we devise a new method cross‐correlating stacked Array Arrays seismic data that provides greatly improved locations, proxy for underlying slow slip, beneath Olympic Peninsula. This increased resolution allows us to image many features were not visible previously. We resolve spatial transition between rupture inter‐ETS...

Abstract We develop a cross‐station method to detect and locate tremor low‐frequency earthquakes (LFEs), based on the original work of Armbruster et al. (2014) that compares waveforms from same time window at stations separated by roughly 10 km. To improve signal‐to‐noise ratio, we first rotate horizontal components into empirical shear wave particle motion direction. The large‐scale “rapid reversals” beneath southern Vancouver Island are best recorded exhibit pronounced splitting, which...

The Clearfield® technology is an useful tool for controlling weedy rice due to the effectiveness of imazamox and cultivation varieties resistant imidazolines. However, residual in soil probably causes phytotoxicity subsequent non-resistant crops. We previously found that pyrroloquinoline quinone (PQQ), a bioactive elicitor, can enhance tolerance imazamox. In this study, we explored molecular mechanism PQQ-mediated by RNA-seq analysis, real-time quantitative PCR (RT-qPCR) assay, enzyme...

Abstract Slow slip events exhibit significant complexity in evolution and variations recurrence intervals. Behavior that varies systematically with interval is likely to reflect different extents of fault healing between these events. Here we use high‐resolution tremor catalogs beneath Guerrero, Mexico, investigate the mechanics slow slip. We observe complex propagation styles, including rapid migrations propagating either along main front or backward, reminiscent those northern Cascadia....

Summary Polyploidy confers a selective advantage under stress conditions; however, whether polyploidization mediates enhanced herbicide adaptation remains largely unknown. Tetraploid Leptochloa chinensis is notorious weed in the rice ecosystem, causing severe yield loss rice. In China, L. has only one sister species, diploid panicea , whose damage rarely reported. To gain insights into effects of on adaptation, we first assembled high‐quality genome and identified structure variations with ....

We find that often occurs in short bursts repeatedly occupy the same source area within a slow slip event. hypothesize these are driven by loading areas surrounding zone. Adopting rate‐and‐state friction law with velocity‐weakening to velocity‐strengthening transition, develop finite fault model which size of zone is larger than Tidal forcing added.
