A research team conducted a study to improve robots' performance in multiple peg-in-hole assembly in adapting to different working scenarios, including different object geometry and pose. Using a flexible and reusable sequential control policy framework, they explored how to apply artificial intelligence technology more efficiently in industrial scenarios. Their sequential control policy framework demonstrated higher training efficiency with faster convergence and a higher success rate compared to the single control policy for long-term multiple peg-in-hole assembly tasks.

The host antimicrobial immune response relies on a complex interplay of molecular mechanisms to effectively combat microbial infections. Herein, we investigate the functional role of Cullin-3 (Cul3), one critical constituent of cullin-RING ubiquitin ligases, in the Drosophila melanogaster (fruit fly) antimicrobial immune defense. We show that silencing of Cul3 leads to a decreased induction of antimicrobial peptides and high mortality in adult flies after bacterial infection. Through biochemical approaches, we demonstrate that Cul3 predominantly relies on its BTB-binding domain and neddylation domain to physically associate with death-associated inhibitor of apoptosis 2 (Diap2). Importantly, Cul3 ameliorates the Diap2-mediated ubiquitination of death-related ced-3/Nedd2-like caspase (Dredd), a process essential for robust immune deficiency signaling upon bacterial infection. Taken together, our findings highlight a previously unrecognized regulatory axis of Cul3/Diap2/Dredd in the fly antimicrobial immune defense, providing potential insights into therapeutic strategies for combating bacterial infections in humans.

A new study reveals that the seasonal march of the mid-Pliocene East Asian summer monsoon was about 10 days earlier than today, providing implications for the future change from a paleoclimate perspective.

Aiming at the small-signal synchronization instability of grid-following (GFL) and grid-forming (GFM) converter system, this paper proposes a synchronization perspective frequency-domain modeling and analysis method, able to intuitively reveal mechanism and accurately judge multi-machine stability. Specifically, a node admittance matrix considering GFL, GFM converters and transmission network is established. Then, the frequency domain modal analysis (FMA) method is adopted to evaluate system instability characteristics. On this ground, synchronization forward and feedback paths are partitioned at the oscillation source, so as to formulate a synchronization perspective stability model incorporating dynamics of each converter and transmission network. Finally, the proposed method has been validated using a typical two-machine GFL-GFM system. With such method, the stability judgment failure caused by the feedback path aggregation is addressed, and the interaction mechanism between GFL and GFM synchronization dynamics is revealed as well as their parameter influences.

Based on the North China Plain, a typical winter wheat-summer maize rotation system was selected by postdoctor Sun Xinzhan from Zhang Junling's research group and associate professor Zhang Jiangzhou from Inner Mongolia Agricultural University. The soil health index and microbial network of 0–15 and 15–30 cm wheat fields with different yields were introduced, and the health status of the top soil and deep soil were evaluated. The relationship between microbials and soil health was revealed, and suggestions were put forward to enhance soil health and improve wheat yield. Better measures were taken to manage farmland soil and achieve green and sustainable development of agriculture while increasing production.
