Computer Monte-Carlo (MC) simulations (Geant4) of neutron propagation and acquisition of gamma response from soil samples was applied to evaluate INS system performance characteristic [minimal detectible level (MDL), sensitivity] for soil carbon measurement. The INS system model with best performance characteristics was determined based on MC simulation results. Measurements of MDL using an experimental prototype based on this model demonstrated good agreement with simulated data. This prototype will be used as the base engineering design for a new INS system.

The lateral prefrontal cortex (LPFC) serves as a critical hub for higher-order cognitive and executive functions in the human brain, coordinating brain networks whose disruption has been implicated in many neurological and psychiatric disorders. While transcranial brain stimulation treatments often target the LPFC, our current understanding of connectivity profiles guiding these interventions based on electrophysiology remains limited. Here, we present a high-resolution probabilistic map of bidirectional effective connectivity between the LPFC and widespread cortical and subcortical regions.

Plasmids are commonly employed in the delivery of clustered regularly interspaced shortpalindromic repeats (CRISPR)/CRISPR-associated (Cas) components for genome editing. However, the absence of heritable plasmids in numerous organisms limits the development of CRISPR/Cas genome editing tools. Moreover, cumbersome procedures for plasmid construction and curing render genome editing time-consuming.

Engineering yeast cell factories is a feasible approach to produce value chemicals from renewable feedstocks. However, during the production process, reprogramming of the internal metabolic pathways of yeast cells and environmental stress always compromises its production performance. Here, we engineered the robust to enhance the production of fatty alcohols by downregulating the expression of target of rapamycin gene and deleting histone deacetylase gene in .

Spodoptera frugiperda is a major crop pest that invaded Thailand in 2018 which cause significant damage, particularly to maize. In recent years, a loss of efficacy of certain insecticides has been observed, suggesting the emergence of resistance. The aim of our study was to investigate the molecular mechanisms of resistance in S.
