Abstract Trait-based analyses have shown great potential to advance our understanding of terrestrial ecosystem processes and functions.However, challenges remain in adequately synthesising a multidimensional and covarying trait space.Reducing the number of studied traits while identifying the most informative ones is increasingly recognized as a pr
BackgroundThe growing HIV epidemic among student men who have sex with men (MSM) necessitates immediate attention from public health.In China, male students who have sex with men (SMSM) were also at an increasing risk of HIV transmission.The aim of this study was to investigate the trends in HIV prevalence, HIV-related risk behaviors, and HIV testi
Simultaneously manipulating multiple physical fields plays an important role in the increasingly complex integrated systems, aerospace equipment, biochemical productions, etc.For on-chip systems with high integration level, the precise and efficient control of the propagation of electromagnetic waves and heat fluxes simultaneously is particularly i
This research designed and developed an ultrasonic reactor for a fast and on demand production of cold brew coffee, remarkably reducing the brewing time from 24 h to less than 3 min.The technology was engineered by utilizing resonance to induce ultrasonic waves around the walls of the brewing basket of an espresso machine.The sound transmission sys
Two kinds of large deflection plane folding hinges, named OSD-LEJ (outside-series-deployed lamina emergent joint) and IOSD-LEJ (inverted-outside-series-deployed lamina emergent joint), are designed with flexible segments arranged in series on the outside, taking into account the inverted design principle.The structures of the two LEJs are designed,
