Authors: Jin Bowen , Geng Jianwei , Ke Shan , Pan Hui 
Published: August 2023

Abstract

Urban street greening is an important part of urban green infrastructure, and Green View Index (GVI) is widely used to assess urban street quality and ecosystem service value as an important indicator to quantify the perception of green street landscape from a pedestrian perspective. However, the distribution of street greenery is imbalanced. Therefore, to explore the differences in street greening levels within urban cities, we crawled streetscape data using the Internet to assess the spatial distribution patterns of urban street GVI using deep learning and spatial autocorrelation, and combined 11 surrounding environmental features with multi-source geographic data to further analyze the key factors influencing the spatial variation of block GVI using ordinary least squares (OLS), geographically weighted regression (GWR) models, and multi-scale geographically weighted regression (MGWR) models. The results show that the mean value of GVI in Fuzhou City is low (23.08%), with large differences among neighborhoods and a significant spatial autocorrelation. Among the regression models, MGWR has the best fit with an R2 of 0.702, where the variables of NDVI, house price, accessibility of water bodies and parks, and the proportion of built-up land have a greater impact on GVI, and the factors do not have the same spatial effect size. The results can provide a scientific basis for promoting green visual equity in different blocks.

Abstract
A Gram-positive, aerobic, rod-shaped non-motile, non-sporulating bacterium, designated CSA2T, was isolated from chromium-containing soils collected from a chemical plant. The 16S rRNA gene sequence of strain CSA2T showed the highest homology with Leucobacter chromiireducens subsp. solipictus (97.85%), Leucobacter chromiireducens subsp. chromiireducens (97.85%). The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values among strains CSA2T and the selected Leucobacter species were 20.6-23.4% (dDDH) and 72.67-78.03% (ANI), falling below the recommended thresholds for species delimitation. The principal fatty acids were anteiso-C15:0, iso-C16:0 and anteiso-C17:0. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol and an unknown glycolipid. The major menaquinones detected were MK-10 and MK-11. The cell-wall amino acids included 2,4-diaminobutyric acid, threonine, glutamic acid，alanine and glycine. Based on molecular feature， phenotypic and chemotaxonomic, strain CSA2T was considered to be a novel species of the genus Leucobacter., and the name Leucobacter edaphi sp. nov. is proposed. The type strain is CSA2T (=JCM 34360T=CGMCC 1.18747T)

Abstract
Purpose: Due to the lack of reliable stigma assessment tools and the stigma faced by people with substance use disorders (SUDs), especially in China. Therefore, this study aimed to validate the Chinese version of the Substance Use Stigma Mechanism Scale (SU-SMS-C) and set its cut-off point.
Methods: We recruited 1005 individuals with SUDs from Chinese rehabilitation centers. These participants completed a battery of questionnaires that included the SU-SMS-C, MSPSS, CES-D, GSES, and PDD. Confirmatory factor analysis was used to assess the construct validity of the scale. Additionally, the Naive Bayes Classifier was used to establish the cut-off point for the SU-SMS-C. We additionally explored the correlation between patient demographic characteristics and stigma.
Results: A confirmatory factor analysis was utilized, revealing a second-order five-factor model. Based on the Naive Bayes Classifier, the Area Under the Receiver Operating Characteristic (AUCROC) of 0.746, the cut-off point for the SU-SMS-C was established at 44.5. The prevalence of stigma observed in the study population was 49.05%. Significant disparities were observed in the distribution of stigma across genders, with males experiencing more pronounced stigma than females. Moreover, patients consuming different primary substances reported diverse levels of stigma. Notably, those primarily using heroin endured a higher degree of stigma than users of other substances.
Conclusion: The study is the first to identify a cut-off point for the SU-SMS-C by Naive Bayes Classifier, bridging a major gap in stigma measurement research. SU-SMS-C may help treat and manage SUDs by reducing stigma.
Digital Justice in the Smart City Developing a Framework for Participatory Digitalisation Strategies at the Local Level

Published: August 2023

Abstract
An integrated consideration of digital inequalities in smart cities is relatively new to most discussions of the subject, and an applicable research framework for the assessment and management of digital inequalities in the smart city is still lacking. This paper proposes a framework for an action-oriented approach to analyse and strategically reduce digital injustices in smart cities. There are five requirements for creating digital justice: the availability of a concept with sufficiently allocated resources, the availability of digital infrastructures and technologies, programmes for learning digital competencies, offerings for citizen participation and a holistic perspective on the global dimensions of digital justice. For different case studies, we assess the coverage, integration and impact of these features. The analysis confirms that the proposed methodological approach can record and evaluate strategies for digital participation in smart cities.
A novel pyrazoline-based turn-on ﬂuorescent probe for highly sensitive detection of Al3+ in aqueous solution and its applications

Published: August 2023

Abstract
A new efficient fluorescent sensor (E)-3-(1-acetyl-5-styryl-4,5-dihydro-1H -pyrazol-3-yl)-4-hydroxy-6-methyl-2H-pyran-2-one (DRS) for Al3+ detection was developed, and the optical properties of DRS were measured in H2O/DMSO (pH = 5.5, 99:1, V/V) solution. DRS showed notable fluorescence enhancement in the presence of Al3+ and had good selectivity and sensitivity to Al3+. Compared to the probes designed by other previous research groups, a lower detection limit (9.13×10-9M) and a shorter response time (14 s) were found. Furthermore, the Job’s plot showed that the stoichiometric ratio among DRS and Al3+ was 1:1, and 1H NMR, IR and DFT calculations showed that the sensing mechanism of the probe DRS for detecting Al3+ was chelation-enhanced fluorescence (CHEF). DRS has also been applied to Al3+ detection in actual water samples, drugs, and HeLa cells, indicating that it has potential application value in the biological process of detecting Al3+ ion.
Structural Changes of the Floats in Kakunodate-Matsuri: Ingenuity for Winning the Festival Bumping Game
Authors: Kubo Mitsunori , Tsubogou Hidehiko 
Published: August 2023

Abstract
The Kakunodate-Matsuri, held in Akita, Japan, is one of the most game-like festivals in which the festival floats are repeatedly 'bumped' against each other in order to win the right of the way. We hypothesised that the accumulation of serious ingenuity by each community that has preserved and operated the floats to win in the 'bumping' might be reflected in the structural form of the floats themselves. To test this hypothesis, we constructed structural models of two floats, one new and one old and carried out collision simulations. As a result, it was confirmed that the floats, which tended to concentrate the impact force at the front of the structure during a collision, were modified to distribute the impact over the entire structure, preventing axle damage due to stress concentration and at the same time reducing the impact on the musicians on board in the middle of the float.

Abstract
BACKGROUND: The controversy surrounding Roux-en-Y and Billroth II with Braun anastomosis as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL.METHODS The clinical data of 151 patients who underwent total laparoscopic distal gastrectomy at the Second Hospital of Fujian Medical University from January 2016 to December 2019 were retrospectively analyzed. Of these, 57 cases with Roux-en-Y anastomosis (R-Y group) and 94 cases with Billroth II with Braun anastomosis were included (BII + B group). Operative and postoperative conditions, early and late complications, endoscopic outcomes at year 1 and year 3 after surgery, nutritional indicators, and quality of life scores at year 3 postoperatively were compared between the two groups.RESULTS The R-Y group recorded a significantly longer operative time (194.65 ± 21.52 min vs. 183.88 ± 18.02 min) and anastomotic time (36.96 ± 2.43 min vs. 27.97 ± 3.74 min) compared to the BII + B group (P < 0.05). However, no other significant differences were observed in terms of blood loss or postoperative conditions (P > 0.05). Both groups showed comparable rates of early and late complications. Endoscopic findings indicated similar food residuals at years 1 and 3 postsurgery for both groups. The R-Y group had a lower occurrence of residual gastritis and bile reflux at year 1 and year 3 after surgery, with a statistically significant difference (P < 0.001). Reflux esophagitis was not significantly different between the R-Y and BII + B groups in year 1 after surgery, but the R-Y group had a lower incidence than the BII + B group in year 3 after surgery (P = 0.023). Nutritional outcomes at 3 years after surgery did not differ significantly between the two groups (P > 0.05). Quality of life scores measured by the QLQ-C30 scale were not significantly different between the two groups. However, on the QLQ-STO22 scale, the reflux score was significantly lower in the R-Y group than in the BII + B group (0 [0, 0] vs. 5.56 [0, 11.11]) (P = 0.003). The rest of the scores were not significantly different (P > 0.05).CONCLUSION Both R-Y and B II + B are equally safe and efficient for TLDG. Nevertheless, R-Y reduces the incidence of residual gastritis, bile reflux, and reflux esophagitis, as well as postoperative reflux symptoms, and provides a better quality of life for patients.
Comprehensive investigation of factor structure and gender equivalence of the Beck Depression Inventory-II among nonclinical adolescents

Published: August 2023

Abstract

The Beck Depression Inventory-II (BDI-II) is a tool widely used to rate the severity of depressive symptoms. Regarding the factor validity of the BDI-II in adolescents, the two-factor solution describing “cognitive” and “somatic-affective” dimensions has been shown to be the most reported. Recently, bifactor model analysis has become popular to describe psychological constructs such as depression. Furthermore, data related to measurement invariance across gender is limited. This study aimed to examine plausible factor structures and gender equivalence of the BDI-II in a Brazilian sample of nonclinical adolescents (N = 1,184, aged 13–18 years, 59.1% females). Cross-validation of the BDI-II was performed through exploratory (EFA) and confirmatory factor analysis (CFA). Measurement invariance was evaluated using multigroup-CFA (MG-CFA). EFA suggested an oblique two-factor model depicting “affective-cognitive” and “somatic" dimensions. Simple structure and bifactor models from literature, as well as the estimated EFA model and its corresponding bifactor model were examined. All factor models revealed adequate and similar fitness, well-defined factors, and good reliability. The goodness-of-fit of bifactor models was slightly superior when compared to simple structure models. Bifactor analyses indicated a robust general factor with low reliable variance in total scores attributed to multidimensionality caused by the group factors in bifactor models. MG-CFA supported invariance across gender, confirming that the same BDI-II construct could be applied to both female and male adolescents. This study provides evidence that the BDI-II could be used by researchers and clinicians as a unidimensional measure of depressive symptoms in the adolescent population.
Identifying the Threshold Discrepancy of Rear-End Conflicts under Clear and Rainy Weather Conditions Using Trajectory Data

Published: August 2023

Abstract
The appropriate threshold selection is pivotal in near-crashes detections. Nevertheless, most cutting-edge warning systems utilize thresholds that are directly derived from general traffic scenarios. There is no evidence support that thresholds acquired from general scenarios can be applied to specific scenarios. Thus, the purpose of this study is to investigate whether thresholds of three surrogate measures of safety (SMoS) differ between the general clear scenario and the special rainy scenario. A total of 1048 rear-end events (724 in clear conditions and 324 in light rain conditions) were obtained from the CitySim dataset. Two threshold selection methods were used to recommend appropriate thresholds. The findings indicated that only MTTC had a statistical difference in two weather scenarios, hence, a threshold was recommended under each of two weather conditions. Furthermore, the MTTC threshold for rainy conditions was three times higher than for clear conditions. Contrarily, the threshold was statistically insignificant for the SPDRF and DRAC under two conditions, so only one integration threshold per SMoS was recommended, even in two scenarios. These findings could help safety-system designers set more targeted and appropriate thresholds when encounter specific characteristics (e.g., weather) for active safety systems or safety warning infrastructures in future smart cities.

Published: August 2023

Abstract
Glycine is a simple amino acid that in high concentration induces morphological transformation, L-form formation and lysis of some microorganism. Glycine interferes in transpeptidation reaction leading to inhibiting the biosynthesis of the bacterial cell wall. Due to bactericidal effect of glycine, in the present work, minimal inhibitory concentration (MIC) of glycine on Helicobacter pylori (H.pylori) was measured. It could be a promising alternative agent against H.pylori in infected patients.
The Complexities of Trans Women’s Access to Healthcare in South Africa: Moving Health Systems Beyond the Gender Binary Towards Equity
Authors: Shabalala Siyanda B. , Campbell Megan M 
Published: August 2023

Abstract
Background: Research in healthcare inequity has shown that health systems are shaped by broader socio-political contexts and biases that shape the institutionalization of healthcare, often leading to significant barriers to inclusive and equitable healthcare access. Health research has, however, overlooked how health systems marginalize gender-diverse persons and sustain health inequities among this population. Trans women, for instance, face multiple layers of exclusion due to their gender identity in health systems that could be considered patriarchal, binary, and cisnormative. Intersectionality-informed research can help challenge these gender structures within healthcare by acknowledging the diversity of identity experiences.
Methods:This study adopts a critical trans politics (CTP) perspective to explore the socio-cultural and political dynamics limiting South African trans women's access to healthcare. Using a critical narrative approach, the research asks:
1) What narratives do South African trans women share about their experiences in health systems?
2) What gendered societal structures, practices, and norms enable or hinder their inclusion in health systems?
Five South African adult trans women between the ages of 22 and 30 participated in semi-structured individual, telephonic interviews that focused on participants' subjective experiences within the healthcare sector.
Results:Trans women are often stigmatized and positioned as outsiders in ciscentric health systems, which uphold traditional gender norms and favour cisgender individuals, while excluding and marginalizing trans positions. Three dominant thematic narratives emerged. First, the denial of trans women’s self-determination reflected in institutional policies and practices that misgender trans women, limited their access to dignified healthcare. Second, the lack of knowledge about gender-affirming healthcare held by healthcare professionals and healthcare institutions led to informational erasure. Third, barriers to accessible and equitable healthcare faced by trans women were compounded by gender, race, and class structural dynamics.
Conclusions:This study sheds light on the challenges faced by South African trans women in accessing appropriate and respectful healthcare, highlighting the need for more inclusive and informed practices in local health systems. In response, a trans-inclusive health equity framework is proposed and its implications for theory, policy, research, and practice are outlined.

Abstract
Aim
To characterize the corneal epithelial thickness (ET) and corneal thickness (CT) profiles in normal eyes of Syrian adults, and to investigate associated factors with central epithelial thickness (CET).
Method
ET and CT were measured by Cirrus high-definition optical coherence tomography (HD-OCT) device in 208 eyes of 104 healthy adults aged 18 to 40 years. The average ET and CT were calculated in 25 (9 mm circle) zones and 17 (7 mm circle) zones, respectively. Correlations of CET with age, refractive errors, keratometry, and central corneal thickness (CCT) were calculated.
Results
The average ET was thicker in the central 2 mm than the paracentral, midperipheral and peripheral zones (50.42 ± 3.51 µm, 49.29 ± 3.61 µm, 47.80 ± 3.54 µm, and 46.74 ± 3.47 µm, respectively), whereas the average CT was thinnest in the centre. While Males have thicker ET than females in all zones (p < 0.05, all), CT did not significantly differ (p > 0.05, all). ET was thinner in the superior area than in the inferior, with the highest difference registered in the peripheral zone (-6 ± 5 µm). We found a positive significant correlation between CET and sphere (r = 0.25, p = 0.0022), and a negative significant correlation between CET and flat keratometry (r = -0.148, p = 0.043). CET was not correlated with age, cylinder or steep keratometry.
Conclusion
We present a comprehensive study in healthy, normal eyes using Cirrus HD-OCT to map the corneal epithelium with a 9 mm diameter. The epithelium was thinner centrally than peripherally and superiorly than inferiorly. Myopic eyes tend to have thinner corneal epithelium than hyperopic eyes. This may help in refractive procedures and in the prediction of corneal diseases.
IGFBP2 drives epithelial-mesenchymal transition in Hepatocellular carcinoma via activating the Wnt/β-catenin pathway

Published: August 2023

Abstract
Metastasis has emerged as a major impediment to achieving successful therapeutic outcomes in hepatocellular carcinoma (HCC). Nonetheless, the intricate molecular mechanisms governing the progression of HCC remain elusive. Herein, we present evidence highlighting the influence exerted by insulin-like growth factor-binding protein 2 (IGFBP2) as a potent oncogene driving the malignant phenotype. Our investigation reveals a marked elevation of IGFBP2 expression in primary tumors, concomitant with the presence of mesenchymal biomarkers in HCC patients. Through in vitro and in vivo experimentation, we demonstrate that the overexpression of IGFBP2 expedites the progression of epithelial-mesenchymal transition (EMT) and facilitates the metastatic potential of HCC cells, chiefly mediated by the Wnt/β-catenin signaling pathway. Notably, the specific activation of Wnt/β-catenin signaling using CHIR-99021 induces heightened nuclear β-catenin accumulation, thereby instigating a mesenchymal phenotype in HCC cells with depleted IGFBP2 expression. Collectively, our findings identify IGFBP2 as a pivotal regulator within the HCC EMT axis, whereby its overexpression confers the distinctly aggressive clinical features characteristic of the disease.
Position as an independent variable and the emergence of the 1/2-time fractional derivative in quantum mechanics
Authors: Beims Marcus Werner , de Lara Arlans JS 
Published: August 2023

Abstract

Using the position as an independent variable, and time as the dependent variable, we derive the function ${\cal P}^{(\pm)}=\pm\sqrt{2m({\cal H}-{\cal V}(q))}$, which generates the space evolution under the potential ${\cal V}(q)$ and Hamiltonian ${\cal H}$. No parametrization is used. Canonically conjugated variables are the time and minus the Hamiltonian ($-{\cal H}$). While the classical dynamics do not change, the corresponding quantum operator ${\cal \hat P}^{(\pm)}$ naturally leads to a $1/2-$fractional time evolution, consistent with a recent proposed spacetime symmetric formalism of the quantum mechanics. Using Dirac's procedure, separation of variables is possible, and while the two-coupled position-independent Dirac equations depend on the $1/2$-fractional derivative, the two-coupled time-independent Dirac equations (TIDE) lead to positive and negative shifts in the potential, proportional to the force. Both equations couple the ($\pm$) solutions of ${\cal \hat P}^{(\pm)}$ and the kinetic energy ${\cal K}_0$ (separation constant) is the coupling strength. Thus, we obtain a pair of coupled states for systems with finite forces, not necessarily stationary states. The potential shifts for the harmonic oscillator (HO) are $\pm\hbar\omega/2$, and the corresponding pair of states are coupled for ${\cal K}_0\ne 0$. No time evolution is present for ${\cal K}_0=0$, and the ground state with energy $\hbar\omega/2$ is stable. For ${\cal K}_0>0$, the ground state becomes coupled to the state with energy $-\hbar\omega/2$, and \textit{this coupling} allows to describe higher excited states in the HO. Energy quantization of the HO leads to the quantization of ${\cal K}_0=k\hbar\omega$ ($k=1,2,\ldots$). For the one-dimensional Hydrogen atom, the potential shifts become imaginary and position-dependent. Decoupled case ${\cal K}_0=0$ leads to plane-waves-like solutions at the threshold. Above the threshold (${\cal K}_0>0$), we obtain a plane-wave-like solution, and for the bounded states (${\cal K}_0<0$), the wave-function becomes similar to the exact solutions but squeezed closer to the nucleus.
