How to minimize adverse effects of physical workplace violence on health sector workers: A preliminary study.

Purpose: This paper is an exploratory study to investigate possible remedial measures accounting for a relatively favorable prognosis of health sector workers who have experienced physical WPV in Zhejiang province, China.

Methods: Following a proportionate stratified sampling strategy, five tertiary hospitals (in the developed capital city of Hangzhou and other prefecture-level cities), eight secondary hospitals (in counties), and thirty-two primary care facilities (16 urban community health centers and 16 rural township health centers) were conveniently selected. Among 4,862 valid respondents out of 6,089 self-conducted questionnaires, 224 health sector workers who have been directly exposed to physical WPV in the past year were included in the present study.

Detecting Streamflow in Dryland Rivers Using CubeSats.

Determining the flow regime of non-perennial rivers is critical in hydrology. In this study, we developed a new approach using CubeSat imagery to detect streamflow presence using differences in surface reflectance for areas within and outside of a river reach. We calibrated the approach with streamflow records in the Hassayampa River of Arizona over 3 years (2019-2021), finding good agreement in the annual fractions of flowing days at stream gages (  = 0.

The poplar VQ1 gene confers salt tolerance and pathogen resistance in transgenic Arabidopsis plants via changes in hormonal signaling.

The VQ protein family is plant-specific, and is involved in growth, development, and biotic and abiotic stress responses. In this study, we found that the gene expression of poplar VQ1(Potri.001G029700) from Populus trichocarpa varied remarkably under salt stress and hormones associated with disease.

Pecan agroforestry systems improve soil quality by stimulating enzyme activity.

Background: Forest and plantation intercropping are efficient agroforestry systems that optimize land use and promote agroforestry around the world. However, diverse agroforestry systems on the same upper-plantation differently affect the physical and chemical properties of the soil.

Methods: The treatments for this study included a single cultivation (CK) pecan control and three agroforestry systems (pecan + + , pecan + , and pecan + ).

How FDI and technology innovation mitigate CO emissions in high-tech industries: evidence from province-level data of China.

The high technology (high-tech) industry of China has gained a key strategic position in the Chinese economic goals. In this positioning, foreign direct investment (FDI) and technological innovation have emerged as strong pillars of the high-tech industry. However, there are growing concerns of carbon emission from this industry which is still debatable.

Responses in Growth and Anatomical Traits of Two Subtropical Tree Species to Nitrogen Addition, Drought, and Their Interactions.

Nitrogen (N) deposition and drought are two major stressors that influence tree growth and propagation. However, few studies have investigated their interactions. In this study, saplings of the two co-occurring species (leguminous) and (non-leguminous) were cultivated under two N addition rates (0 and 80 kg N ha year) with well-watered (WW, 80% of field capacity), moderate drought (MD, 60% of field capacity), and severe drought conditions (SD, 40% of field capacity).

Networked multiple-input-multiple-output for optical wireless communication systems.

Heat stress tolerance determines the survival and growth of introduced Canadian sugar maple in subtropical China.

The introduction of species contributes to both ecological restoration and regional economics, while serving as a potential strategy to conserve species under rapid climate change. Despite an anticipated significant increase in temperature at high latitudes by the end of the 21st century, very few experimental migration trials have been conducted regarding large climate range changes. We employed a provenance trial by introducing a temperate sugar maple (Acer saccharum Marsh) of three provenances with a mean annual temperature of 3.

Fluorous interaction induced self-assembly of tobacco mosaic virus coat protein for cisplatin delivery.

Tobacco mosaic virus coat protein was modified with a small molecular fluorous ponytail at specific sites, and self-assembled into spherical nanoparticles through fluorous interaction induced self-assembly. By loading the anti-cancer drug cisplatin through metal-ligand coordination, this spherical assembly with high stability has potential as a drug carrier.

Transcriptome analysis of pecan seeds at different developing stages and identification of key genes involved in lipid metabolism.

Pecan is an economically important nut crop tree due to its unique texture and flavor properties. The pecan seed is rich of unsaturated fatty acid and protein. However, little is known about the molecular mechanisms of the biosynthesis of fatty acids in the developing seeds.

Programming Self-Assembly of Tobacco Mosaic Virus Coat Proteins at Pickering Emulsion Interfaces for Nanorod-Constructed Capsules.

Pickering emulsion constructions on nanorods with high aspect ratio are a great challenge because of the geometry restrictions. On the basis of the theory that the stability of Pickering emulsion is highly dependent on the size and amphiphilicity of the nanoparticle at fluid interfaces, we report a novel strategy to fabricate long-time stable Pickering emulsion consisting of tobacco mosaic virus (TMV)-like nanorods through the programming self-assembly of TMV coat protein (TMVCP). The first step is the self-assembly of amphiphilic TMVCP at Pickering emulsion interfaces, and the second step is the in situ interfacial self-assembly of TMVCP into nanorods with increased particle size.

Glyco-decorated tobacco mosaic virus as a vector for cisplatin delivery.

Plant viruses have been applied broadly in nanomedical applications profiting from their monodisperse structure, biocompatibility, easy modification, and non-pathogenicity in animals. Here we report a tobacco mosaic virus (TMV) based drug delivery system bearing carbohydrates as targeting ligands. Mannose (Man) and lactose (Lac) moieties were separately conjugated to the exterior surface of TMV (TMV-Man and TMV-Lac) through an efficient copper(i)-catalyzed azide-alkyne cycloaddition.

Receiver design for SPAD-based VLC systems under Poisson-Gaussian mixed noise model.

Single-photon avalanche diode (SPAD) is a promising photosensor because of its high sensitivity to optical signals in weak illuminance environment. Recently, it has drawn much attention from researchers in visible light communications (VLC). However, existing literature only deals with the simplified channel model, which only considers the effects of Poisson noise introduced by SPAD, but neglects other noise sources.

BICM-ID scheme for clipped DCO-OFDM in visible light communications.

Visible light communication (VLC) is recommended for indoor transmissions in 5G network, whereby DC-biased optical orthogonal frequency division multiplexing (DCO-OFDM) is adopted to eliminate the inter-symbol interference (ISI) but suffers from considerable performance loss induced by clipping distortion. In this paper, bit-interleaved coded modulation with iterative demapping and decoding (BICM-ID) scheme for clipped DCO-OFDM is investigated to enhance the performance of VLC systems. In order to further mitigate the clipping distortions, a novel soft demapping criterion is proposed, and a simplified demapping algorithm is developed to reduce the complexity of the proposed criterion.

Layered ACO-OFDM for intensity-modulated direct-detection optical wireless transmission.

Layered asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) with high spectral efficiency is proposed in this paper for optical wireless transmission employing intensity modulation with direct detection. In contrast to the conventional ACO-OFDM, which only utilizes odd subcarriers for modulation, leading to an obvious spectral efficiency loss, in layered ACO-OFDM, the subcarriers are divided into different layers and modulated by different kinds of ACO-OFDM, which are combined for simultaneous transmission. In this way, more subcarriers are used for data transmission and the spectral efficiency is improved.

An adaptive scaling and biasing scheme for OFDM-based visible light communication systems.

Orthogonal frequency-division multiplexing (OFDM) has been widely used in visible light communication systems to achieve high-rate data transmission. Due to the nonlinear transfer characteristics of light emitting diodes (LEDs) and owing the high peak-to-average-power ratio of OFDM signals, the transmitted signal has to be scaled and biased before modulating the LEDs. In this contribution, an adaptive scaling and biasing scheme is proposed for OFDM-based visible light communication systems, which fully exploits the dynamic range of the LEDs and improves the achievable system performance.

Enhancing the decoding performance of optical wireless communication systems using receiver-side predistortion.
