Observation of many-body dynamical localization.

The quantum kicked rotor is a paradigmatic model system in quantum physics. As a driven quantum system, it features dynamical localization, specifically Anderson localization in momentum space. However, the interacting many-body kicked rotor is believed to break localization.

The GRAIN SIZE 8-GRAIN LENGTH 10 module controls the grain size in rice by regulating the expression of GA- and CTK-related genes.

Rice grain size is an important agronomic trait that affects the grain weight and yield of rice (Oryza sativa). In this study, genome-wide association studies (GWASs) were performed regarding grain length (GL), grain width (GW), grain thickness (GT), the grain length-width ratio (GLWR) and the 1000-grain weight (TGW) across 172 rice accessions in 2020, 2021 and 2022. Among the 31 QTLs identified across all 3 years, the QTL qGL8/qGW8/qGT8/qGLWR8 on chromosome 8 was newly discovered in our study.

Transitioning towards hydrogen powered seaport yard cranes for low carbon transformation based on a multiple factor real option model.

Recently, more and more seaports have actively adjusted the energy structure of yard cranes to achieve green and low-carbon transition. Hydrogen energy, with its advantages of high efficiency and environmental friendliness, has become a crucial energy source for the low-carbon transition. Based on real options theory, this paper developed a cost-benefit model and proposed investment options for hydrogen-powered yard crane construction projects.

Anaemia in pregnancy: can we improve care?

Introduction: Maternal anaemia is the most common condition in pregnancy. It has profound consequences for both the mother and child, despite being easily treatable with iron supplementation. Our study aimed to investigate its prevalence, risk factors, and the current compliance to screening and treatment.

Coral calcium hydride promotes peripheral mitochondrial division and reduces AT-II cells damage in ARDS via activation of the Trx2/Myo19/Drp1 pathway.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models.

Genome-wide association study identifies elite alleles of FLA2 and FLA9 controlling flag leaf angle in rice.

Background: In hybrid rice seed production, rice varieties with a small flag leaf angle (FLA) experience obstacles to cross-pollination at the early heading stage, and farmers usually need to remove flag leaves to achieve artificial pollination. Therefore, the cultivation of rice varieties with large FLAs can not only save a substantial amount of labour in the leaf-cutting process during artificial pollination but also accelerate the mechanization of hybrid rice seed production.

Results: In this study, 431 rice accessions were included in a genome-wide association study (GWAS) to identify quantitative trait loci (QTLs) and the superior haplotypes for rice FLA in 2022 and 2023.

Floodplain inundation in the Murray-Darling Basin under current and future climate conditions.

Predicting floodplain inundation under a changing climate is essential for adaptive management of water resources and ecosystems worldwide. This study presents a framework combining satellite observations and hydrological modeling to explore changes in floodplain inundation. We examine variability, trends, and frequency of inundation across the Murray-Darling Basin (MDB), Australia's largest river system, over the past 35 years (1988-2022).

Effect of intravenous lidocaine on Ciprofol dose in patients undergoing painless gastrointestinal endoscopy: a double-blinded, randomized, controlled trial.

Background: Ciprofol (CIP) for procedural sedation and analgesia (PSA) for painless gastrointestinal endoscopy (GE) can cause respiratory or cardiovascular complications. The literature suggests that intravenous (IV) lidocaine infusion can alleviate visceral pain and enhance humans' ventilator response to CO. Therefore, it was hypothesized that IV lidocaine could reduce the CIP dose for painless GE and improve recovery time.

Elite Alleles of EPE1 Identified via Genome-wide Association Studies Increase Panicle Elongation Length in Rice.

Panicle elongation length (PEL), which determines panicle exsertion, is an important outcrossing-related trait. Mining genes controlling PEL in rice (Oryza sativa L.) has great practical significance in breeding cytoplasmic male sterility (CMS) lines with increased PEL and simplified, high-efficiency seed production.

Biparametric MRI-based radiomics for noninvastive discrimination of benign prostatic hyperplasia nodules (BPH) and prostate cancer nodules: a bio-centric retrospective cohort study.

To investigate the potential of an MRI-based radiomic model in distinguishing malignant prostate cancer (PCa) nodules from benign prostatic hyperplasia (BPH)-, as well as determining the incremental value of radiomic features to clinical variables, such as prostate-specific antigen (PSA) level and Prostate Imaging Reporting and Data System (PI-RADS) score.

Hydrogen alleviates impaired lung epithelial barrier in acute respiratory distress syndrome via inhibiting Drp1-mediated mitochondrial fission through the Trx1 pathway.

Acute respiratory distress syndrome (ARDS) is an acute and severe clinical complication lacking effective therapeutic interventions. The disruption of the lung epithelial barrier plays a crucial role in ARDS pathogenesis. Recent studies have proposed the involvement of abnormal mitochondrial dynamics mediated by dynamin-related protein 1 (Drp1) in the mechanism of impaired epithelial barrier in ARDS.

The effect of different endotracheal tube cuff pressure monitoring systems on postoperative sore throat in patients undergoing tracheal intubation: a randomized clinical trial.

Background: Postoperative sore throat (POST) is an unpleasant outcome that can occur as a result of tracheal intubation in adults. Increased pressure from the endotracheal tube (ETT) cuff often leads to local mucosal injury, resulting in sore throat. The purpose of this study was to compare the effect of two different ETT cuff pressure monitoring systems vs.

The dataset covers the period from 1988 to 2022 at two-monthly timestep and was developed using remotely sensed imagery and a flood depth estimation model at a spatial resolution of ≈30 m, providing a comprehensive picture of maximum observed inundation depth across the MDB.

Carotid wall imaging with 3D_T2_FFE: sequence parameter optimization and comparison with 3D_T2_SPACE.

Similar to sampling perfection with application-optimized contrast using different flip angle evolutions (SPACE), T2-weighted fast field echo (FFE) also has a black blood effect and a high imaging efficiency. The purpose of this study was to optimize 3D_T2_FFE and compare it with 3D_T2_SPACE for carotid imaging. The scanning parameter of 3D_T2_FFE was optimized for the imaging of the carotid wall.

Piezoelectric property comparison of two-dimensional ZnO nanostructures for energy harvesting devices.

In this paper, experimental and theoretical studies of the piezoelectric effect of two-dimensional ZnO nanostructures, including straight nanosheets (SNSs) and curved nanosheets (CNSs) are conducted. The results show that the CNSs have a great advantage in piezoelectric property over the SNSs; the maximum output current of the NG based on CNSs was measured to be about 260 nA, much higher than that generated by SNSs. For comparatively analyzing the working mechanics of both NGs, the piezopotential distribution of both CNS and SNS structures was studied using the finite element method.

Provably-secure (Chinese government) SM2 and simplified SM2 key exchange protocols.

We revisit the SM2 protocol, which is widely used in Chinese commercial applications and by Chinese government agencies. Although it is by now standard practice for protocol designers to provide security proofs in widely accepted security models in order to assure protocol implementers of their security properties, the SM2 protocol does not have a proof of security. In this paper, we prove the security of the SM2 protocol in the widely accepted indistinguishability-based Bellare-Rogaway model under the elliptic curve discrete logarithm problem (ECDLP) assumption.
