Published: August 2023

Abstract
In recent years, coherent electrons driven by light fields have attracted significant interest in exploring novel material phases and functionalities1–4. However, observing coherent light-field-driven electron dynamics5,6 in solids is challenging because the electrons are scattered within several ten femtoseconds in ordinary materials, and the coherence between light and electrons is disturbed. However, when we use Weyl semimetals7–11, the electron scattering becomes relatively long (several hundred femtoseconds - several picoseconds), owing to the suppression of the back-scattering process12. This study presents the light-field-driven dynamics by the THz pulse (~1 ps) to Weyl semimetal Co3Sn2S213–20, where the intense THz pulse of a monocycle electric field nonlinearly generates direct current (DC) via coherent acceleration without scattering5,6 and non-adiabatic excitation1,5,21,22 (Landau–Zener Transition). In other words, the non-Ohmic current appears in the Weyl semimetal with a combination of the long relaxation time and an intense THz pulse. This nonlinear DC generation also demonstrates a Keldysh crossover23 from a photon picture to a light-field picture by increasing the electric field strength.

Authors: Wang Chenwei 
Published: August 2023

Abstract
These days, the logistics industry has experienced remarkable growth as global economic integration and cross-border e-commerce trade accelerate. However, this growth has brought about significant ecological and environmental challenges. This study analyzes the connection between China's cross-border e-commerce logistics market and the low-carbon economic system. The objective is to reduce carbon emissions in the logistics industry, minimize regional pollutant emissions, and bridge the carbon emission gap across different regions. The research employs Genetic Algorithm optimization to strike a trade-off between cross-border trade and carbon emissions. Eviews 6.0 software is used to analyze the relationship between the cross-border e-commerce logistics industry and the rate of low-carbon economic growth, represented by the carbon emission intensity index. Different trade volume combinations for each region in China are explored and evaluated based on their corresponding carbon emissions. The goal is to minimize carbon emissions while maintaining the same trade level. Additionally, an AI-based predictive model, combining the Genetic Algorithm and Autoregressive Integrated Moving Average (ARIMA) forecasting, is employed to validate the optimization results. The Genetic Algorithm provides optimal points for low carbon emissions, and the ARIMA forecast predicts the optimal solution for the following year. The findings indicate that the optimized solution significantly reduces carbon emissions compared to the original values.
Enhancing Copyright Protection of Online Literature using Intelligent Decision Support Systems and Blockchain Technology
Authors: Wei Na 
Published: August 2023

Abstract
Copyright protection is one of the most important aspects of every organization. The traditional copyright protection mechanisms are posed to several challenges, including permitting data loss and simple access, which leads to security issues. On the other hand, blockchain technology has increased IoT security and changed many areas, including copyright protection, by increasing the income of copyright holders. Keeping the important and significant role of blockchain technology in different fields of life in consideration, this paper tries to integrate this secure technology with decision support systems (DSS) and presents a blockchain-based intelligent decision support system (IDSS) system to secure online literary copyright. This study initially discusses the significance of IDSS in the copyright protection of online literature by providing a full definition of blockchain technology, including its types, properties, and algorithms. After that, we discuss the integration of IDSS with blockchain technology to protect online literary copyright. The proposed system facilitates professional copyright validation, infringement monitoring, unbiased digital information, and efficiency in legal review. Finally, we developed a blockchain-based literary protection platform model based on the proposed system to protect online literature copyright. The experimental results illustrate that the proposed method reduces the loss and increases accuracy. The experimental results reveal that mobile terminal loss decreased by 11.3% between 2018 and 2020, while PC terminal online literary piracy decreased by 1.7%.
EGFR-mediated crosstalk between vascular endothelial cells and hepatocytes promotes Piezo1-dependent liver regeneration
Authors: Liu Juan , Hu Yuelei , Du Guifang , Li Chao , Wang Rui , Wang Yunfang , Dong Jiahong 
Published: August 2023

Abstract
Hepatocyte proliferation is essential for recovering liver function after injury. In liver surgery, the mechanical stimulation induced by hemodynamic changes triggers vascular endothelial cells (VECs) to secrete large amounts of cytokines that enhance liver cell proliferation and play a pivotal role in liver regeneration. Piezo1, a critical mechanosensory ion channel, can detect and convert mechanical forces into chemical signals, importing external stimuli into cells and triggering downstream biological effects. However, the precise role of Piezo1 in VECs, especially in terms of mediating liver regeneration, remains unclear. Here, we report on a potential mechanism by which early changes in hepatic portal hemodynamics activate Piezo1 in VECs to promote hepatocyte proliferation during the process of liver regeneration induced by portal vein ligation (PVL) in rats. In this liver regeneration model, hepatocyte proliferation is mainly distributed in zone 1 and zone 2 of liver lobules at 24–48 h after surgery, while only a small number of Ki67-positive hepatocytes were observed in zone 3. Activation of Piezo1 promotes increased secretion of epiregulin (EREG) and amphiregulin (AREG) from VECs via the PKC/ERK1/2 axis, further activating epidermal growth factor receptors (EGFR) and ERK1/2 signals in hepatocytes and promoting proliferation. In addition, cytokines secreted by Piezo1-activated VECs can induce hepatocytes to undergo epithelial-mesenchymal transition (EMT). In the liver lobules, the expression of EGFR in hepatocytes of zone 1 and 2 is significantly higher than that in zone 3. The EGFR inhibitor gefitinib inhibits liver regeneration by suppressing the proliferation of hepatocytes in zones 1 and 2. Thus, activation of Piezo1 in VECs promotes hepatocyte proliferation, suggesting mechanical stimulation regulates hepatocyte proliferation in zones 1 and 2 during PVL-induced liver regeneration. These data provide a theoretical basis for the regulation of liver regeneration through chemical signals mediated by mechanical stimulation.
Percentage change in hemoglobin is closely linked to the one-year mortality rate in elderly patients who have suffered hip fractures
Authors: Zhou Ling , Huang Chao , Zhu Xianjie , Ma Zhenhua 
Published: August 2023

Abstract
Purpose The objective of this study was to examine the relationship between the percentage change in hemoglobin (ΔHb) and 1-year mortality among patients who underwent hip fracture surgery. Percentage ΔHb was defined as: ([preoperative Hb - nadir Hb]/preoperative Hb) × 100.
Methods A total of 636 patients with hip (including femoral neck and intertrochanteric femur) fractures who were hospitalised at an orthopaedic centre in China from January 2016 to December 2020 were reviewed as study subjects. General data were collected from patients, who underwent internal fixation or artificial femoral head replacement, and patients were followed up in outpatient clinics and by telephone for 1 year after surgery. The clinical value of predicting patient death was analysed using subject work characteristics (ROC) curve analysis, and multifactorial cox regression analysis was used to explore the influencing factors of death in elderly hip fracture patients at 1 year postoperatively.
Results Over the course of the year following surgery, 108 patients (17.0%) passed away. The study found that a ΔHb value of 28.1% was the optimal cutoff for predicting mortality, with a sensitivity of 67.6% and specificity of 74.1%. Patients who had higher ΔHb levels had a significantly higher mortality rate (34.8% vs. 8.2%, p 0.001), and after adjusting for other factors, high ΔHb remained an independent predictor for one-year all-cause mortality (HR 4.12, 95% CI 2.66–6.39, p 0.001). Other independent risk factors for survival included advanced age, Charlson comorbidity index (CCI) >2, Blood transfusion, low albumin level, and longer length of stay. Additionally, the findings from subgroup analysis were generally in agreement with the main results across most stratified groups.
Conclusions The percentage change in hemoglobin levels was found to be independently linked to the risk of mortality within one year. These outcomes indicate that utilizing percentage ΔHb as a metric could aid in identifying patients who are at a heightened risk for 1-year mortality.

Published: August 2023

Abstract

Background
We investigated the association between reproductive agency and subjective well-being among respondents of reproductive age in four African countries.
Methods
We used nationally representative data from the World Values Survey (WVS) conducted in Ethiopia, Kenya, Nigeria, and Zimbabwe between 2017–2021 (N = 4,948). Subjective well-being was measured using four items on perceived: i) life satisfaction (range 1–10), overall life agency (range 1–10), health status (range 1–5), and happiness (range 1–4). Reproductive agency was measured by asking respondents to rank their freedom of choice and control over whether, when, and how many children to have (range 1–10). Pearson’s chi-squared test, bivariate, and multivariable logistic regression were used to compare subjective well-being between respondents of high vs low reproductive agency using the median as cutoff, stratified by country and sex, calculating adjusted odds ratios (aOR) and 95% confidence intervals (CI).
Results
The analytical sample included 4,302 respondents. Half (55%) rated their reproductive agency as high (median 8; IQR = 5). Two-thirds (66%) rated their life satisfaction as high (median 5; IQR = 4), and half (51%) their overall life agency as high (8; IQR = 5). Most (75%) reported themselves as healthy (median 4; IQR = 2) and happy (median 3; IQR = 1). In adjusted analyses, high reproductive agency was associated with higher life satisfaction (aOR 1.28, 95% CI 1.11–1.46) and overall life agency (aOR 3.65 95% CI 3.20–4.17). When stratifying by sex and country, associations remained for respondents in Nigeria and Zimbabwe and women.
Conclusions
As fertility is increasingly politicized, we contribute with person-centered and human rights-based indicators that are necessary to inform rights-based policies.

Abstract
To characterize and compare macular vessel density in central retinal artery occlusion (CRAO) eyes with retinal arterial cannulation and CRAO eyes with standard treatment. This study was Cross-sectional, observational study. Twenty-two eyes with nonarteric CRAO which underwent retinal arterial cannulation and 19 eyes with nonarteric CRAO with standard treatment were included. Optical coherent tomography angiography (OCTA)-based macular vessel density and visual acuity were examined. The dynamic ranged-based normalized rates of vessel density was compared within each group at the first visit to the clinic and 7 days after the onset. Macular vessel density in cannulation group was significantly better at 7 days after the onset than that at the first visit (3.73 ± 3.02 mm-1vs. 7.89 ± 1.02 mm-1, P = .0001), while there wasn’t significant improvement of macular vessel density in standard treatment group at 7 days after the onset (2.13 ± 1.62 mm-1 vs. 2.89 ± 0.22 mm-1, P = .067). At one month after the onset, mean LogMAR visual acuity in CRAO eyes with cannulation significantly improved compared with that at the first visit after the onset (1.678 vs. 0.979, P = .00012). Macular vessel density loss in CRAO eyes was improved by retinal arterial cannulation. Early intervention of retinal arterial cannulation is useful for minimizing visual impairment in CRAO eyes.
Nitrogen-doped Titanium Dioxide as a novel eco-friendly Hole Transport Layer in Lead-Free CsSnI3 based Perovskite Solar Cells
Authors: Seyed-Talebi Seyedeh Mozhgan , Lee Chi-Hao 
Published: August 2023

Abstract
Despite recent abrupt rise in the efficiency of perovskite solar cells (PSCs), the contact layers maybe limit the efficiency of PSCs. The hole transporting layer (HTL) is an essential layer for reducing the recombination and loosing charges in fabricated devices by avoiding direct contact of gold to perovskite absorber layer in an efficient PSC device. The pristine spiro-OMeTAD, as most widely used HTL, still suffers from poor electrical conductivity, low hole mobility, and low oxidation rate. In this research, the nitrogen doped TiO2 (N-TiO2) proposed as a low-cost, efficient, safe replacement for spiro-OMeTAD HTL in PSCs. The variation in the device design key parameters such as the thickness and bulk defect density of perovskite layer, simultaneous modifications of defect density and defect energy level, and acceptor doping concentration in absorber layer are examined with their impact on the photovoltaic characteristic parameters. The effect of an increase in operating temperature from 280 K to 460 K on the performance of CsSnI3-based perovskite devices is also investigated. The standard simulated lead-free CsSnI3–based PSCs with spiro-OMeTAD HTL by SCAPS-1D software revealed the highest power conservation efficiency (PCE) of 23.63%. The CsSnI3-based solar cell with N-TiO2 as HTL showed FF (79.65%), VOC (0.98 V), Jsc (34.69 mA/cm2), and efficiency (27.03%) higher than the standard device with conventional spiro-OMeTAD HTL. The outcomes of N-TiO2 presence as an HTL signify a critical avenue for the possibility of fabricating high PCE CsSnI3-based perovskite devices made of stable, low-cost, efficient, safe, and eco-friendly materials.

Abstract
Accurate tree detection is of growing importance in applications such as urban planning, forest inventory, and environmental monitoring. In this article, we present an approach to creating tree maps by annotating them in 3D point clouds. Point cloud representations allow the precise identification of tree positions, particularly stem locations, and their heights. Our method leverages human computational power through paid crowdsourcing, employing a web tool designed to enable even non-experts to effectively tackle the task. The primary focus of this paper is to discuss the web tool's development and strategies to ensure high-quality tree annotations despite encountering noise in the crowdsourced data. Following our methodology, we achieve quality measures surpassing 90% for various challenging test sets of diverse complexities. We emphasize that our tree map creation process, including initial point cloud collection, can be completed within 1-2 days.

Published: August 2023

Abstract
Background
Glyphosate-based herbicides (GBHs) are used extensively around the world and have become the leading agrochemicals. However, study about the association between glyphosate exposure and diabetes is scarce. This study used four years of NHANES data (2013–2016) to further investigate the association.
Methods
A total of 2,806 participants were enrolled in this cross-sectional study. The baseline information and urine glyphosate levels in diabetic and non-diabetic groups were compared. We also divided urine glyphosate levels into tertiles. Three models were developed using weighted logistic regression. Further subgroup analyses based on categorical variables were also conducted.
Results
Urine glyphosate levels were 0.35ng/ml in people with diabetes and 0.44ng/ml in participants without diabetes (P < 0.05). Regardless of adjustment, the highest glyphosate level in the tertile3 group was significantly linked with an elevated risk of diabetes (OR 1.595, 95% CI 1.016–2.504, P = 0.043) compared to the tertile1 group. Subgroup analyses suggested that the associations were constant in participants who were male, older age (60–100), had a college degree, income ratio = 5, BMI > 30, and smoking.
Conclusions
This study provides new evidence that glyphosate exposure was associated with a higher risk of diabetes in the American general adult population.
Subsidies, Speed and Switching? Impacts of an Internet Subsidy in Colombia
Authors: Hidalgo Julian , Sovinsky Michelle 
Published: August 2023

Abstract
Inequality in access to health, education, and employment opportunities is exacerbated in developing nations due to the uneven distribution of access to high-speed internet connections. In Colombia, the government enacted a policy (in 2012) to subsidize internet fees for low-income households to bridge the digital divide. The reductions were not granted to all plans and thus created incentives for consumers to switch between plans. We estimate a structural model of demand for internet connection plans, which we use to quantify the importance of switching behavior. We estimate the model using data on plans offered by all internet service providers to households in all socioeconomic (SES) groups across Colombia. Our results indicate that the subsidy caused a non-negligible fraction of low-SES households to switch internet plans - the majority of which switched to plans with lower speeds not higher speeds. Furthermore, the more wealthy households (of the lower SES groups) were twice as likely to switch plans than those in the lowest SES group. Our findings suggest that the impact, not only on internet adoption, but also on switching behavior should be taken into account when formulating subsidies designed to bridge the digital divide.
