Summary: Through shotgun metagenomic sequencing, the genetic basis and metabolic pathways of keratinolytic microorganisms in an enriched bacterial consortium were elucidated. The analysis of metagenomic data predicted keratinases and metabolic pathways associated with keratin degradation, revealing potential metabolic cooperation among community members and the significance of synergistic interactions.

Summary: This study elucidated the bacterial community succession, metabolic pathway, and phytotoxicity assessment during beta-cyfluthrin biodegradation by a novel bacterial consortium enriched from contaminated soil. The results showed that the synergistic effect of the microbial community is more conducive to the complete degradation of toxic compounds than a single strain.

Summary: Sexual dimorphism can have significant implications for the coexistence, abundance, and dynamics of consumer and resource species, particularly when there are sex differences in attack rates and resource acquisition by the consumer.

Summary: Bdellovibrio bacteriovorus can attack biofilms of the pathogen Vibrio cholerae, but the prey biofilms are protected from their predators once they reach a critical maturation threshold. This protection mechanism is determined by the relative contributions of matrix secretion and cell-cell packing of the prey biofilm.

Summary: This article proposes an improved droop strategy to optimize the efficiency of parallel inverters. The strategy selects an optimal number of inverters based on their efficiency curve to process fractions of the power demand, and introduces an online inverter detection method to deal with light load situations. Experimental results demonstrate that this method can significantly improve system efficiency and enhance system reliability under light load conditions.

Summary: The study investigated the successional variation of bacterial community and metabolism during the enrichment culture of a phthalate-degrading consortium. Results showed a significant increase in extracellular polymeric substances (EPS) during domestication, while bacterial richness and diversity decreased significantly. Proteobacteria and Bacteroidetes became dominant phyla associated with phthalate tolerance and degradation. The microbial interaction networks revealed a coexistence of mutualism and competition among members of the bacterial consortium.

Summary: Ascensao et al. engineered knockout libraries of a nascent bacterial community and found that ecological and epistatic patterns combine to shape adaptive landscapes, despite idiosyncratic behavior of individual knockouts. The study also revealed that fitness effects are correlated with evolutionary outcomes for certain conditions, indicating shifting patterns of adaptation.

Summary: The study examines the genome-wide diversity in moose populations in Sweden and finds limited impacts of the 1900s near-extinction event, but local variations in inbreeding, genetic load, and a risk of future reduction in genetic diversity and gene flow. The findings also indicate candidate genes for local adaptation and rapid temporal allele frequency shifts related to selective harvesting.

Summary: This article proposes a modified LLC resonant converter with an LC antiresonant circuit in the parallel branch. Compared to the LLC resonant converter, this new design reduces the equivalent inductance of the parallel branch at increasing switching frequencies. The proposed converter also optimizes the resonant parameters in the parallel branch to achieve a close-to-sine-wave magnetizing current and reduce conduction losses. Experimental results show the feasibility of this design and its advantages over the LLC resonant converter.

Summary: Predators can indirectly affect community structure through nonconsumptive effects on foundation species, as demonstrated in this study where Acanthina monodon reduced larviphagy and filtration rates of Perumytilus purpuratus. The field experiment showed higher colonization rates of invertebrates and lower algal biomass in mussel beds in the presence of predator cues, altering community structure.

Summary: In this study, a microalgae-based process was evaluated for the removal of sulfonamide antibiotics (SAs) in wastewaters. The results showed that the process had a high removal efficiency for sulfamethoxazole, but a lower efficiency for sulfadiazine. The presence of SAs did not significantly inhibit biomass production, but caused a decrease in polysaccharide content and an increase in protein content, leading to granule formation. The presence of SAs also resulted in increased lipid peroxidation activity.

Summary: This article presents a novel virtual ground robot (VGR) device for human-balance training. The device utilizes parallel legs to overcome limitations and achieve large force and impedance, as well as significant compliance. The dynamics and kinematics of the VGR are analyzed, and a spatial impedance control method is designed. The performance of the developed robot device is validated experimentally.
