[Tillage Depth Regulation and the Effect of Straw Return on Soil Respiration in Farmland].

Straw return and tillage depth treatments are one of the most important agricultural management measures that affect farmland soil respiration, but the mechanism of their interaction affecting farmland soil respiration remains unclear. Therefore, 116 published research articles were used through Meta-analysis technology for dryland farmland ecosystems in China to explore the effects of straw return and tillage depth treatments and their interaction on farmland soil respiration and its regulatory factors, which will provide important data support and a theoretical basis for achieving "carbon neutrality" in farmland ecosystems. The results showed that no tillage reduced soil respiration by 8.

Universal Mirror-Stacking Approach for Constructing Topological Bound States in the Continuum.

Bound states in the continuum (BICs) are counterintuitive localized states with eigenvalues embedded in the continuum of extended states. Recently, nontrivial band topology is exploited to enrich the BIC physics, resulting in topological BICs (TBICs) with extraordinary robustness against perturbations or disorders. Here, we propose a simple but universal mirror-stacking approach to turn nontrivial bound states of any topological monolayer model into TBICs.

USP7- and PRMT5-dependent G3BP2 stabilization drives de novo lipogenesis and tumorigenesis of HNSC.

GTPase-activating protein-binding protein 2 (G3BP2) is a key stress granule-associated RNA-binding protein responsible for the formation of stress granules (SGs). Hyperactivation of G3BP2 is associated with various pathological conditions, especially cancers. Emerging evidence indicates that post-translational modifications (PTMs) play critical roles in gene transcription, integrate metabolism and immune surveillance.

The main results are as follows: (1) There is a significant positive correlation between city size and the cost of household travel.

Acoustic Möbius Insulators from Projective Symmetry.

In the presence of gauge symmetry, common but not limited to artificial crystals, the algebraic structure of crystalline symmetries needs to be projectively represented, giving rise to unprecedented topological physics. Here, we demonstrate this novel idea by exploiting a projective translation symmetry and constructing a variety of Möbius-twisted topological phases. Experimentally, we realize two Möbius insulators in acoustic crystals for the first time: a two-dimensional one of first-order band topology and a three-dimensional one of higher-order band topology.

Topological dislocation modes in three-dimensional acoustic topological insulators.

Dislocations are ubiquitous in three-dimensional solid-state materials. The interplay of such real space topology with the emergent band topology defined in reciprocal space gives rise to gapless helical modes bound to the line defects. This is known as bulk-dislocation correspondence, in contrast to the conventional bulk-boundary correspondence featuring topological states at boundaries.

MnO switch-bridged DNA walker for ultrasensitive sensing of cholinesterase activity and organophosphorus pesticides.

Cholinesterases (ChEs) are important indicators of neurological disease, hepatocellular carcinoma, and organophosphate poisoning. In this work, a MnO switch-bridged DNA walker was developed for ultrasensitive sensing of ChEs activity. The fuel strands loaded MnO switch was designed to bridge the hydrolysis activity of ChEs and the running of the DNA walker.

Ultrasensitive detection of butyrylcholinesterase activity based on the inner filter effect of MnO nanosheets on sulfur nanodots.

Butyrylcholinesterase (BChE) activity is an important index for a variety of diseases. In this work, a "turn-on" assay is proposed based on controlling the inner filter effect (IFE) of MnO nanosheets (NSs) on sulfur nanodots (S-dots). The fluorescence of S-dots is effectively quenched by the MnO NSs, due to the wide overlap of the emission spectrum of S-dots and absorption spectrum of MnO NSs, together with the superior light absorption capability of MnO NSs.

The effect of intradialytic combined exercise on hemodialysis efficiency in end-stage renal disease patients: a randomized-controlled trial.

Purpose: Insufficient dialysis is a difficult problem for patients undergoing hemodialysis, and causes cardiovascular complications and increases mortality. Increasing aerobic exercise and resistance exercise have been shown to be beneficial to physical fitness of patients undergoing hemodialysis, but a few studies have focused on combined exercise (combination of aerobic and resistance exercise training) and the interaction effect of combined exercise and intervention duration on hemodialysis efficiency. This study aimed to investigate the effects of 24-week combined exercise on hemodialysis efficiency, blood pressure, exercise capacity, and quality of life in patients undergoing hemodialysis.

Hydrogen Peroxide Assisted Synthesis of Highly Luminescent Sulfur Quantum Dots.

An H O -assisted top-down approach is used to synthesize brightly luminescent, color-tunable sulfur quantum dots (SQDs), with a photoluminescence quantum yield of up to 23 %. The formation of SQDs involves dissolution of bulk sulfur powder into small particles in an alkaline environment in the presence of polyethylene glycol, followed by H O -assisted etching of polysulfide species, which has the advantage of the passivation of surface states. This synthetic strategy allows us to simultaneously control the final size of SQDs, to tune their emission color, and to improve their emission quantum yield by eliminating surface traps.
