Influence of Liquid Level Height on Flow Characteristics and Mixing Efficiency in a Loop Bioreactor by Fan Xu, Xiaoping Guan, Ning Yang, Maximilian Lackner

“…Conversely, elevated liquid levels ([Formula: see text]) enhance diffusion-driven mixing, shortening mixing time by 2/3 at [Formula: see text] compared to [Formula: see text] A critical transition from convection-dominated to diffusion-dominated regimes is identified at [Formula: see text] with mixing efficiency becoming less sensitive to stirring speed at [Formula: see text] These findings provide feasible guidelines for optimizing loop scalability and advancing reactor optimization strategies for continuous bioprocessing.…”

Mapping Workplace Inclusion in Hierarchical Collectivist Societies: A Causal Loop Diagram Approach by Toronata Tambun, Gatot Yudoko, Leo Aldianto

“…Unlike frameworks that treat collectivism as a static cultural trait, CLDs provide a dynamic lens to analyze how workplace inclusion evolves through structured feedback loops—revealing how structured exclusivity in collectivist systems governs trust, inclusion, and legitimacy not through ideology alone, but through relational sponsorship, time-dependent trust, and group-based gatekeeping. …”

SC-CFDMA uplink symbol synchronization method based on multi-rate satellite-ground loop by Dan DING, Nai-ping CHENG, Yu-rong LIAO

“…SC-CFDMA(single carrier code and frequency division multiple access) system,whose synchronization is more difficult than that of common orthogonal multi-carrier systems,requires the symbol synchronization to achieve a chip-level precision.Therefore,a synchronization method based on multi-rate satellite-ground loop is proposed.This method extends the closed-loop control on the non-sampling points of the loop through raising the control rates of some loop components,so as to promote the adaptability to users with different speeds.Besides,the state-space equations of the loop and related components are derived.The Matlab simulation results show that,even in GEO satellite system,the synchronization method proposed can adjust the SC-CFDMA uplink symbol timing errors between several supersonic users within chip-level duration,thus providing stable communication.…”
