Frequency transfer and inverse design for metasurface under multi-physics coupling by Euler latent dynamic and data-analytical regularizations.

Frequency transfer is a key challenge in machine learning as it allows researchers to go beyond in-range analyses of spectrum properties towards out-of-the-range predictions. Traditionally, to predict properties at a specific frequency, targeted spectrum is included in training data for a deep neural network (DNN). However, due to limitations of measurement or computation source, training data at some frequencies are hardly accessible, especially for multi-physics problems.

What kind of matching groups makes students benefit more? The role of reviewer expertise and document quality within-groups.

Peer feedback has proven to be practically helpful for students in achieving learning outcomes, especially through peer feedback among students in matching achievement groups. However, some researchers have raised concerns about whether students would be better served by being matched with different achievement groups rather than 'random' or same-level matching methods. No studies have investigated whether other ways of matching groups would change outcomes.

Genome-Wide Identification of the Gene Family in Sea-Island Cotton () and the Active Regulation of Drought Resistance in Cotton by .

Cotton is an economically critical crop worldwide, and drought stress strongly affects its growth and development. Ubiquitination modifies protein activity and is crucial in numerous biological processes. Ubiquitin-conjugating enzymes serve as intermediaries in the protein ubiquitination process and play important roles in plant responses to abiotic stress.

Sources and formation characteristics of particulate nitrate in the Pearl River Delta region of China: Insights from three-year online observations.

Nitrate (NO) has been identified as a key component of particulate matter (PM) in China. However, there is still a lack of understanding regarding its sources and how it forms, especially in the context of high-frequency and long-term data. In this study, NO levels were observed on an hourly basis over an almost three-year period at an urban site in the Pearl River Delta (PRD) region, China, from January 2019 to December 2021.

USP31 Activates the Wnt/β-catenin Signaling Pathway and Promotes Gastric Cancer Cell Proliferation, Invasion and Migration.

Background: Gastric cancer (GC) has a poor prognosis because it is highly aggressive, yet there are currently few effective therapies available. Although protein ubiquitination has been shown to play a complex role in the development of gastric cancer, to date, no efficient ubiquitinating enzymes have been identified as treatment targets for GC.

Methods: The TCGA database was used for bioinformatic investigation of ubiquitin-specific protease 31 (USP31) expression in GC, and experimental techniques, including Western blotting, qRT-PCR, and immunohistochemistry, were used to confirm the findings.

Molecular signatures and formation mechanisms of water-soluble chromophores in particulate matter from Karachi in Pakistan.

Excitation-emission matrix (EEM) fluorescence spectroscopy is a widely-used method for characterizing the chemical components of brown carbon (BrC). However, the molecular basics and formation mechanisms of chromophores, which are decomposed by parallel factor (PARAFAC) analysis, are not yet fully understood. In this study, we characterized the water-soluble organic carbon (WSOC) in aerosols collected from Karachi, Pakistan, using EEM spectroscopy and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).

[Changes in Health Risks and Pollution Sources of Atmospheric PM-bound Metals in a Background Site in North China].

To explore the change features of PM-bound metals in a background site of North China in the past ten years, 71 and 160 samples were collected from December 2011 to January 2013 (period Ⅰ) and from September 2019 to November 2021 (period Ⅱ) in Tuoji Island National Atmospheric Monitoring Station, respectively.The concentration of metals sampled was determined using ICP-MS, and the concentrations, sources, and health risks of heavy metals were compared. The results revealed that the average concentration of PM was (54.

Isotopic comparison of ammonium between two summertime field campaigns in 2013 and 2021 at a background site of North China.

Ammonia (NH) is the primary atmospheric alkaline gas, playing a crucial role in the atmospheric chemistry. Recently, non-agricultural emissions have been identified as the dominant sources of NH in urban areas. However, few studies have quantified the contributions of different sources to regional NH.

Diagnostic test accuracy of PCR by saliva specimen for cytomegalovirus infection in newborn: A protocol for systematic review and meta-analysis.

Background: This study aimed to assess the diagnostic accuracy of polymerase-chain-reaction by saliva.

Method: We searched Pubmed, EMBASE, Cochrane Library and Web of Science. A case-control or cohort study designed to explore the saliva specimens for diagnosing the cytomegalovirus infection was eligible for this study.

Nitrogen isotopic composition of NO from residential biomass burning and coal combustion in North China.

Stable nitrogen isotope (δN) technology has often been used as a powerful tool to separate nitrogen oxides (NO) produced by residential combustion (i.e., biomass burning and coal combustion) from other sources.

New Insights into Unexpected Severe PM Pollution during the SARS and COVID-19 Pandemic Periods in Beijing.

During the SARS period in 2003 and COVID-19 pandemic period in 2020, unexpected severe particulate matter pollution occurred in northern China, although the anthropogenic activities and associated emissions have assumed to be reduced dramatically. This anomalistic increase in PM pollution raises a question about how source emissions impact the air quality during these pandemic periods. In this study, we investigated the stable Cu and Si isotopic compositions and typical source-specific fingerprints of PM and its sources.

[Association between the inter-aural latency difference of brainstem auditory evoked potential wave V and neonatal hyperbilirubinemia].

Objective: To study brainstem auditory evoked potential (BAEP) in neonates with hyperbilirubinemia using short auditory stimuli (60 dBnHL), and to investigate the differences in the inter-aural latency difference (ILD) of wave V between neonates with different total serum bilirubin (TSB) levels.

Methods: A prospective study was conducted in neonates with hyperbilirubinemia who were admitted to the Department of Neonatology, Yuhuan People's Hospital of Zhejiang Province, from May 2019 to October 2020. The neonates were divided into a severe group (=50) and a mild group (=50) according to their TSB levels.
