Summary: The multiphase flow of droplets is widespread and used for both biological and nonbiological applications alike. The ensemble interactions of such systems are inherently nonlinear and complex, making it a difficult many-body problem. In contrast with the established paradigm of inertial microfluidics, we find novel self-assembly dynamics of liquid drops in microfluidic channels, where ordering can be negatively correlated with inertia and long-range spatial periodicity can be achieved by Dean flow.

Summary: Nowadays, music streaming services provide users with instant access to a vast amount of music from all genres. This study focuses on understanding the patterns of music propagation across different countries, using a directed-graph structure to analyze frequent song propagation between countries. The resulting patterns show strong correlations with migratory flows and cultural similarities among regions, providing potential predictors for anticipating the popularity and mobility of songs. The findings can be valuable for record companies and artists in planning marketing campaigns and events.

Summary: A novel acoustic streaming tweezers-enabled microfluidic immunoassay was proposed, allowing for probe particles' purification, reaction, and sensing on the same chip under continuous-flow conditions. The high-speed microscale vortexes enable dynamic trapping and washing of the probe particles and enhance the capture efficiency of heterogeneous particle-based immunoassay through active mixing during trapping. This system achieved a limit of detection of 0.2 ng/mL and a dynamic response range from 0.3 to 10 ng/mL for prostate-specific antigen sensing with only 10 μL of sample in less than 15 minutes total assay time, making it suitable for on-site diagnosis applications.

Summary: This study presents a method for trapping and collecting airborne particulate matter using an ultrasonic device system, which has been validated through numerical simulations and experiments and investigated the impact of various parameters on collection performance. Due to its contactless and mild handling attributes, this ultrasonic airborne particulate matter sampler can avoid clogging and secondary pollution issues compared to other methods.

Summary: Microfluidics is a versatile and promising technology that offers cost-effectiveness, rapid analysis time, and compact equipment footprint. However, achieving controlled and versatile microfluidic motion within implantable devices is a challenge. This study proposes a novel bidirectional micro-pump design using sharp-edge microcantilever arrays driven by ultrasound, enabling selective flow direction by manipulating the ultrasound frequency. Numerical simulation and parametric analysis demonstrate the feasibility and performance optimization of this design. This work provides valuable guidance for the practical development of sharp-edge-based acoustic micro-pumps, particularly for potential implantable applications.

Summary: Reproductive interactions among closely related plant species through pollination may play a significant role in community assembly and co-occurrence. Outcrossing congeners are more likely to co-occur in sites lacking congeners, while selfers tend to be more common in communities with multiple congeners. Flower size and reliance on outcrossing were found to be key factors influencing co-occurrence patterns among Trifolium species.

Summary: Microbes play crucial roles in biogeochemical cycles of metalloids in mining and smelting areas. Researches have shown significant distance-decay of microbial communities across geographic distances, with differences influenced by soil factors, spatial variations, and metalloid levels. Dispersal limitation and homogeneous selection were found to govern microbial assemblies in different sites, with pH and metalloid levels affecting the deterministic and stochastic processes of microbial communities.

Summary: The sustainability of estuarine ecosystem functions relies on the stability of microbial ecological processes, which are lacking in-depth studies due to the unique and variable habitat characteristics of estuarine areas. This study used sequencing technologies to investigate the composition, diversity, spatial pattern, and aggregation mechanism of bacterial, protist, and fungal communities in the Pearl River Estuary. The assembly process of the microbial communities was primarily driven by stochastic processes, with undominated processes being the most critical. Environmental variables, geographic locations, and biological factors were associated with the composition and assembly of the microbial communities, with dissolved oxygen and salinity being the main predictors.

Summary: This study investigates the variability of CHL-a in the oceanic area of Sri Lanka, considering different monsoon patterns, maritime zones, and the influence of SST and IOD. The highest mean CHL-a value was observed during the southwest monsoon in the continental shelf off Southern Sri Lanka. Within the upwelling zone off the Southern coast, CHL-a showed a negative correlation with SST and IOD, and a positive correlation with wind speed.

Summary: This study investigates the migration behavior of juvenile Atlantic salmon during their freshwater and marine phases. The research reveals that the smolts have a rapid migration speed in crossing the Irish Sea, and populations further away from the migration starting point exhibit lower migration success. Additionally, the smolts show preferences for water current direction and temperature, and are able to use other cues to navigate during migration.

Summary: The study optimized the ultrasound-assisted pregelatinization starch (UAPS) process through a computational fluid dynamics model, revealing that increasing probe diameter generates more turbulence among bubbles, accelerating heat and mass transfer; the maximum radius of bubbles increases with probe size, amplitude, and temperature, while bubble energy slightly increases with liquid temperature and probe size.

Summary: By analyzing camera trapping data collected from Pullen Pullen reserve in southwestern Queensland from 2014 to 2020, the researchers investigated the spatial and temporal activity patterns of feral cats. The study found that the probability of feral cat detection decreased with increasing ruggedness and increased as distance to creek lines decreased. These findings provide important information for the management of feral cats.

Summary: This paper describes an innovative experimental setup that uses audio technology principles to subject adherent cells to rhythmic vertical vibrations. The setup's performance is evaluated using a new approach that combines three-axis acceleration measurements and particle tracking velocimetry. The findings show that mechanical stimuli have a significant impact on the size and orientation of F-actin filaments, as well as the accumulation of cells in the G1 phase of the cell cycle.
