Abstract Background To investigate the current status of public education on endocrine and metabolic diseases through WeChat official accounts (WOAs) of academic medical journals in China and to identify the factors that...

Abstract Substantial efforts have been made to modernize and decarbonize the waste collection industry. Smart sensor-based waste collection (SWC) systems have been developed to optimize collection routes based on the act...

ObjectiveThe aim of the study was to examine the relationships between dietary intake of amino acids and the risk of hypertension and to find some important amino acids as the targets of intervention in Chinese children ...

The COVID-19 pandemic prompted several drug repositioning initiatives with the aim to rapidly deliver pharmacological candidates able to reduce SARS-CoV-2 dissemination and mortality. A major issue shared by many of the ...

Abstract Locoregional CAR-T delivery is increasingly explored for glioblastoma to improve intracranial tumor exposure; however, organ-level biodistribution kinetics after intracranial administration remain poorly quantif...

Thermoplastic polymers have emerged as compelling alternatives to conventional thermosets in response to increasing environmental concerns, primarily due to their superior recyclability and enhanced sustainability charac...

Abstract Broadband Power Line Communication (BB-PLC) technology enables data transmission for smart grid applications. Nevertheless, channel equalizers are required in the receiver to estimate and compensate for the nonl...

Optimization methods are valuable for making decisions and identifying the most suitable alternative based on a given objective function. One of the mathematical optimization methods is Conjugate Gradient (CG) method whi...

The operational efficiency of fleet aircraft employed for student flight training in collegiate aviation programs is strongly influenced by scheduling, among other factors. The average utilization rate for the fleet oper...

Powder compaction is the most widely used technology to fabricate polymer bonded explosives (PBX), and its parameters significantly influence the structures and mechanical properties of the final products. By conducting ...

Water-scarce smallholder regions require irrigation strategies that are both biophysically credible and socially legitimate. We propose an integrated hydro-economic decision-support framework for the Cesar Department (Co...

The knowledge and the ability to describe the phase equilibrium behavior of systems composed of transesterification products are very important in the optimization of biodiesel production and purification process. In thi...

Abstract Microrobotic systems offer significant potential for precision medicine by enabling minimally invasive interventions in complex fluidic environments. However, effective operation in these settings requires actua...

Source-grid-load-storage coordinated operation control is an operation mode and technology that can maximize the utilization of energy resources, and can economically, efficiently and securely improve the power dynamic b...

The seismic load has an adverse effect on the bearing capacity of the footings. However, few studies are performed to study its impact on the bearing capacity of slopes. In this study, a rigorous analysis in the framewor...

Abstract In the realm of ultra-intense laser physics, the precise characterization of laser pulses is indispensable for ensuring optimal peak power and experimental fidelity. However, accurate measurement of spatiotempor...

Alteration of muscle activation sequence is a key mechanism in heart failure with reduced ejection fraction. Successful cardiac resynchronization therapy (CRT), which has become standard therapy in these patients, is lim...
