Stomatal movement plays an essential role in plant responses to drought stress, and the actin cytoskeleton abscisic acid (ABA) are two important components of this process. Little is known about mechanism underlying remodeling dynamic changes occurring during stomatal response stress/ABA signaling. Actin-depolymerizing factors (ADFs) conserved severing/depolymerizing proteins eukaryotes, angiosperms ADFs have evolved actin-bundling activity. Here, we reveal that transcriptional expression...
This minireview summarizes analytical methods based on the light-scattering of plasmonic nanoparticles, primarily gold nanoparticles (AuNPs), at single particle level from recent year publications. Examples are presented to illustrate simple and highly sensitive approaches AuNP localized surface plasmon resonance with dark-field microscopy imaging technology.
Deploying deep learning models on embedded systems for computer vision tasks has been challenging due to limited compute resources and strict energy budgets. The majority of existing work focuses accelerating image classification, while other fundamental problems, such as object detection, have not adequately addressed. Compared with detection problems are more sensitive the spatial variance objects, therefore, require specialized convolutions aggregate information. To address this need,...
Existing language models usually require large amount of labeled data and are severely challenged by domain shift. In this work we propose a novel model for cross-domain sentiment classification - CLIM Contrastive Learning with mutual Information Maximization, to explore the potential contrastive learning domain-invariant task-discriminative features. To best our knowledge, is first investigate classification. Due scarcity labels on target domain, introduce information maximization (MIM)...
Crystalline microwires of a phenyleneethynylene (PE) macrocycle self-assembled from solution exhibited superior photoconductive properties. Photoswitches fabricated with single wires afforded nA-scale photocurrents on/off ratios ca. 10(3). At bias 30 volts highest gain value achieved was up to 4.5. The stable and rapid responses light qualify these microwire-based devices for excellent photoswitches or photodetectors.
Natural killer/T-cell lymphoma (NKTCL) is a highly aggressive malignancy with dismal prognosis, and gaps remain in understanding the determinants influencing disease outcomes. To characterise gut microbiota feature identify potential probiotics that could ameliorate development of NKTCL. This cross-sectional study employed shotgun metagenomic sequencing to profile two Chinese NKTCL cohorts, validation conducted an independent Korean cohort. Univariable multivariable Cox proportional hazards...
Silver-enhanced fluorescence was coupled with a bio-barcode assay to facilitate dual amplification demonstrate non-enzymatic approach for simple and sensitive detection of DNA. In the design, magnetic nanoparticles seeded silver were modified capture DNA, binding ssDNA fluorescently labeled barcode dsDNA. Upon introduction target sandwich structure formed because hybridization reaction. By separation, silver-enhanced DNAs could be readily measured without need further step liberate from...
An effective <italic>C</italic>-glycosylation protocol using <italic>N</italic>-(glycosyloxy)acetamides as donors promoted by SnBr<sub>4</sub> has been developed, delivering alkyl <italic>C</italic>-glycosides and aryl-β-<italic>C</italic>-glycosides in high yields.
Root hair is a polarly elongated single-celled tissue that derives from root epidermal cell for uptake of water and nutrient the surrounding environment. Previous reports have demonstrated short periods high pH inhibited extension, however, effects long-term high-pH treatment on growth hairs still unclear. Here, we reported duration elongation significantly prolonged with increasing external pH, which counteracts effect decreasing rate ultimately produces longer hairs, whereas loss...
In this work we provide a systematic scanning tunneling microscopy (STM) study on the self-assembling and mixing behavior of Arylene Ethynylene Macrocycles (AEMs) containing 1,4-phenylene, 1,4-naphthylene or 9,10-anthrylene substituents at solid/liquid interface. The effect bulky self-assembly structure was investigated found that 1,4-phenylene ethynylene macrocycle (AEM-B) (AEM-N) form four three different patterns 1,2,4-trichloride benzene (TCB)/graphite interface, respectively,...
A one-sided remote toehold design was proposed to provide the fine control over strand-displacement reaction kinetics with simplicity and versatility.
This paper introduces a novel Attention-based Bidirectional Long Short-Term Memory (Bi- LSTM) model for detecting stress in social media text, aiming to enhance mental health monitoring the digital age. Utilizing unique communicative nature of media, this study employs user-generated content analyze emotional and levels. The proposed incorporates an attention mechanism with Bi-LSTM architecture improve identification temporal features context relationships text data, which is crucial...
Domain adaptive text classification is a challenging problem for the large-scale pretrained language models because they often require expensive additional labeled data to adapt new domains. Existing works usually fails leverage implicit relationships among words across In this paper, we propose novel method, called Adaptation with Structured Knowledge (DASK), enhance domain adaptation by exploiting word-level semantic relationships. DASK first builds knowledge graph capture relationship...
After hours of teaching astrophysicists TensorFlow and then see them, nevertheless, continue to struggle in the most creative way possible, we asked, What is point all these efforts?
Root hairs are single-cell projections in the root epidermis. The presence of greatly expands surface, which facilitates soil anchorage and absorption water nutrients. also ideal system to study mechanism polar growth. Previous research has identified many important factors that control different stages hair development. Using a chemical genetics screen, this we report identification steroid molecule, RHP1, promotes growth at nanomolar concentrations without obvious change other...

This dissertation examines whether having more children makes Chinese parents better off economically later in life. While can provide support, are expensive and deplete resources because they take up both money time. However, little is known the causal relationship between number of parents’ long-term income wealth. Most studies neglected certain characteristics influencing life, i.e. endogeneity. None analyzed complete picture elderly economic resources. The present study addressed...
