Distributed Fixed-Time Control for Leader-Steered Rigid Shape Formation With Prescribed Performance.

Resorting to the principle of rigid body kinematics, a novel framework for a multirobot network is proposed to form and maintain an invariant rigid geometric shape. Unlike consensus-based formation, this approach can perform both translational and rotational movements of the formation geometry, ensuring that the entire formation motion remains consistent with the leader. To achieve the target formation shape and motion, a distributed control protocol for multiple Euler-Lagrange robotic vehicles subject to nonholonomic constraints is developed.

USP25 inhibition ameliorates Alzheimer's pathology through the regulation of APP processing and Aβ generation.

Down syndrome (DS), or trisomy 21, is one of the critical risk factors for early-onset Alzheimer's disease (AD), implicating key roles for chromosome 21-encoded genes in the pathogenesis of AD. We previously identified a role for the deubiquitinase USP25, encoded on chromosome 21, in regulating microglial homeostasis in the AD brain; however, whether USP25 affects amyloid pathology remains unknown. Here, by crossing 5×FAD AD and Dp16 DS mice, we observed that trisomy 21 exacerbated amyloid pathology in the 5×FAD brain.

Contributions of enhanced endogenous microbial metabolism via inoculation with a novel microbial consortium into an anoxic side-stream reactor to in-situ sludge reduction for landfill leachate treatment.

In-situ sludge reduction plays a significant role in reducing excess sludge production. This study investigated the role of beneficial microorganisms (BM) in the anoxic-oxic-settling-anoxic (A-OSA) process associated with the in-situ sludge reduction efficiency under synthetic landfill leachate treatment. The rates of excess sludge reduction with the inoculation of BM increased up to 53.

Control effect of functional strength training for aerobics sports injury.

Objective: The study was carried out to improve scientificity in aerobics training, reduce sports injury and boost further development of aerobics.

Methods: In the study, 1000 aerobics athletes from sports colleges were selected as research subjects. In this study, the prevention and treatment effect of functional strength training on calisthenics injury was analyzed.

Low temperature advanced nitrogen and sulfate removal from landfill leachate by nitrite-anammox and sulfate-anammox.

Under anaerobic conditions, ammonium (NH) can react with nitrite (NO) and sulfate (SO), termed nitrite-anammox (NirAnammox) and sulfate-anammox (Sulfammox), respectively. However, how to remove NH and SO together from leachate is unclear. In this study, NirAnammox and Sulfammox cooperatively achieved nitrogen and sulfate removal from leachate using a biological process at low temperature (14-15 °C).

Cooperation between partial-nitrification, complete ammonia oxidation (comammox), and anaerobic ammonia oxidation (anammox) in sludge digestion liquid for nitrogen removal.

The challenge of sludge digester liquor treatment is its high ammonium nitrogen (NH-N) concentration. Early reports found that complete ammonia oxidation (comammox) was not present and anaerobic ammonia oxidation (anammox) was difficult to achieve in most sludge digester liquor treatments. In this study, NH-N removal by cooperation between partial-nitrification, comammox, and anammox processes was achieved in a sequencing batch reactor (SBR) for sludge digester liquor treatment.

Low energy treatment of landfill leachate using simultaneous partial nitrification and partial denitrification with anaerobic ammonia oxidation.

An up-flow anaerobic sludge blanket reactor (UASB), anoxic/oxic (A/O)-anaerobic ammonia oxidation reactor (ANAOR or anammox reactor), and anaerobic sequencing batch reactor (ASBR) were employed in the treatment of landfill leachate with partial nitrification-anammox and half-denitrification-anammox. The Chemical Oxygen Demand (COD) concentration, ammonium nitrogen (NH-N) concentration, and total nitrogen (TN) concentration of the basal leachate was 2200-2500 mg/L, 1200-1300 mg/L, and 1300-1400 mg/L, respectively. After a 1:2 dilution using domestic sewage, the COD, NH-N, and TN concentrations in the influent were 800-1000 mg/L, 400-430 mg/L, and 420-440 mg/L, respectively.
