AtTRM11 as a tRNA 2-methylguanosine methyltransferase modulates flowering and bacterial resistance via translational regulation.

2-methylguanosine is an eukaryote-specific modified nucleoside in transfer RNAs, and mG10 is catalyzed by Trm11-Trm112 protein complex in eukaryotic tRNAs. Here, we show that loss-of-function mutation of the Arabidopsis Trm11 homolog AtTRM11 resulted in mG deficiency associated with disturbed ribosome assembly and overall transcriptome changes, including genes involved in flowering regulation and plant-pathogen interaction. The attrm11 mutant showed phenotypes of enlarged rosette leaves and early flowering, as well as enhanced resistance to Pseudomonas bacterial infection.

Removal of harmful components from MSWI fly ash as a pretreatment approach to enhance waste recycling.

Municipal solid waste incineration (MSWI) fly ash contains many harmful components that may limit its potential for recycling. An effective pretreatment is therefore required before any recycling can be implemented. In this study, the effects of four pretreatment methods (water washing, CO-aided washing, CO-aided washing, and CO and CO-aided washing) on the extraction behavior of chloride, sulfate, and heavy metals were evaluated.

COVID-19 Detection from X-ray Images using Multi-Kernel-Size Spatial-Channel Attention Network.

Novel coronavirus 2019 (COVID-19) has spread rapidly around the world and is threatening the health and lives of people worldwide. Early detection of COVID-19 positive patients and timely isolation of the patients are essential to prevent its spread. Chest X-ray images of COVID-19 patients often show the characteristics of multifocality, bilateral hairy glass turbidity, patchy network turbidity, etc.

Thermal remediation of cyanide-contaminated soils：process optimization and mechanistic study.

Site soils with persistent cyanide compounds (primarily iron-cyanide complex) pose potential hazards to the environment and require remediation before redevelopment. This study evaluated the possibility of thermal treatment on remediation of cyanide-contaminated soils via batch heating experiments spanning a wide temperature range (200-500 °C). The change with operation variables of total cyanide and some reaction intermediates (e.
