Published: September 2021

Abstract
With the proportion of automobile industry in people's work and life increasing year by year, the automotive intelligent terminal market has ushered in a huge development prospect. On-board information system is a set of control system used to collect, store and display all kinds of information status in the process of automobile running. Controller Area Network (CAN) is a serial communication field bus network that effectively supports distributed monitoring or real-time control. Through the CAN bus technology, the vehicle-mounted intelligent terminal can easily interact with other devices in the automobile, so as to master the running status of the vehicle. The vehicle-mounted 3D acquisition system continuously acquires the traveling position of the measuring vehicle through GPS, and provides geographic coordinates for the 3D spatial images acquired by the measuring vehicle, thus realizing the 3D scene with spatial geographic coordinates. Relying on CAN bus and GPS technology, the vehicle-mounted intelligent terminal can conveniently obtain the surrounding road condition information and send its own vehicle data to the remote control center.

Published: September 2021

Abstract
With the rapid development of Internet technology, the scale of online transactions is constantly expanding. At the same time, the related network transaction fraud problem has become more significant. Compared with the credit card transaction, the network transaction has the characteristics of low cost, wide coverage and high frequency, which makes the detection of fraud more complex. Aiming at the problem of difficult fraud detection in network transactions, this paper designed two fraud detection algorithms based on Fully Connected Neural Network and XGBoost, whose AUC values can achieve 0.912 and 0.969 respectively. Meanwhile, we designed an interactive online transaction fraud detection system based on XGBoost model, which can automatically analyze the transaction data uploaded and return the fraud detection results to users.

Abstract
This paper presents the detailed simulation of a
double-pixel structure for charged particle detection based on the
3D-trench silicon sensor developed for the TIMESPOT project and a
comparison of the simulation results with measurements performed at
the π-M1 beam at PSI laboratory. The simulation is based on the
combined use of several software tools (TCAD, GEANT4, TCoDe and
TFBoost) which allow to fully design and simulate the device physics
response in very short computational time,
O(1–100 s) per simulated signal, by exploiting
parallel computation using single or multi-thread processors. This
allowed to produce large samples of simulated signals, perform
detailed studies of the sensor characteristics and make precise

Abstract
The characteristics of urban green space have context-dependent associations with socioeconomic status (SES). Latin American cities provide a unique but understudied context to assess the green space-SES associations. We measured the quantity and quality of green space as greenness from satellite-derived Normalized Difference Vegetation Index, and we modeled the relationship between greenness and SES in 371 major Latin American cities between 2000 and 2015. We found that SES was negatively associated with average greenness at city and sub-city scales, which could be explained by urbanization generally improving SES while reducing the provision of green space. About 82% of the cities and 64% of the sub-cities experienced greening or increases in greenness over time. Although with lower average greenness, cities with higher SES had greater greening; however, it was the opposite for sub-cities. We suggest that greening is more likely to take place in peripheral sub-cities where SES tends to be lower. The findings challenge the belief that places with higher SES have better access to environmental resources and amenities; instead, this relationship is context dependent.
In vitro anti-oxidant property and reduction of hyperglycemia-induced oxidation by hydroalcoholic extract of Phyllanthus emblica in cultured mesangial cell lines
Authors: Sridharan B , Zhang J M , Lee M J 
Published: September 2021

Abstract
The pathology of diabetic nephropathy (DN) is due to long-term poor blood sugar control leading to changes in the filtration unit of the kidneys. However, drugs used to offer renal protection cause many side effects. Therefore, it is necessary to develop a new drug or food supplement that acts on multiple factors of DN. Studies have confirmed that Phyllanthus emblica (PE) has anti-diabetic, free radical scavenging, anti-inflammatory, immune regulation, antipyretic, analgesic, wound healing, anti-atherosclerosis, liver protection, kidney protection, and neuroprotection properties. In this study, we explored the antioxidant activity and ability to maintain redox balance in MES-13 cell line. We performed DPPH and FRAP assay to detect the antioxidant property of PE. SDS-PAGE was performed to understand the changes in the types of protein of the glomerular cells treated (24 hr) with high sugar (25 mM) with/without PE extract (10 & 100 μg/ml). Oxidative stress in cells was detected by RedCC-1 staining. Significant antioxidant activity was shown by the extract (IC50 – 108.9 μg/ml) compared to Trolox (IC50 – 60.9 μg/ml). The protein pattern of high glucose (25 mM) treated cells significantly reduced compared to normal and PE treated cells. Mitochondrial dysfunction and cellular oxidative stress produced by high glucose (intensity - 222.04 units) supplementation was significantly reduced by PE (intensity - 38.67 units). In conclusion, PE extract possesses an antioxidant property that can reduce the glomerular damage and oxidative stress in the cells caused by high glucose exposure
Evaluation of kombucha tea as a feed additive for improving the protein and lipid retention of African catfish (Clarias gariepinus)
Authors: Aprianus M Y , Lamid M , Kenconojati H 
Published: September 2021

Abstract
Kombucha tea is the product of sugared tea fermentation by a symbiotic culture of bacteria and yeast. This beverage contains a high source of the microbial community, such as acetic acid bacteria, lactic acid bacteria, and yeast, which may serve as an alternate source of probiotics. The present study aimed to investigate the effect of dietary enriched kombucha tea at different levels on the protein and lipid retention of African catfish (Clarias gariepinus). A total of 400 fish, with an average initial weight of 5.26±0.11 g, were randomly divided into five treatments. The diet treatment containing different volumes of added kombucha tea (4 mL, 6 mL, 8 mL, and 10 mL per kg of feed) was given and compared to the control, without kombucha addition. The fed was given at satiation three times a day for 30 days. The result showed a significant increase (P<0.05) in protein and lipid retention in the groups that received kombucha tea addition, compared to the control group. Kombucha tea addition at 8 mL/kg of feed resulted in the highest protein and lipid retention, but the addition above this value showed a slight decrease in protein and lipid retention. Overall, the present study proved that the addition of kombucha at the optimum levels in diet could improve the protein and lipid retention of fish, which are related to the fish’s somatic growth. These results provide evidence of the potential application of kombucha tea in the aquaculture industry as a feed additive, especially for probiotic sources.
Effect of andrographolide on the pathological events during the surgical open wound healing process
Authors: Sridharan B , Lin Y L , Liao J W , Wang S , Lee M J 
Published: September 2021

Abstract
Wound healing is an important physiological process and several natural and synthetic drugs are being tested to speed up the process to avoid infection and other undesirable pathological events. Although andrographolide has been reported to be an excellent bioactive compound that can influence multiple pathways in the cells, its wound healing property has not been widely appreciated. In this study, we wanted to exhibit the improvement in the pathological events concerning wound healing process by injecting andro in a surgical wound model in rats. The right paw of female SD rats was operated and after 5 days, pathological events in the operated right paw was observed by staining the sections using hematoxylin & eosin dyes to elucidate the dermal and epidermal changes, while Mason’s trichrome staining was performed on the sections to show the granulation layer formation and provide supporting evidence for angiogenesis and ECM deposition. Pathological score was given to the sections according to the extent of the changes observed and the results suggested that epidermal changes were scored almost similar in both saline and andro injected rats (2-3), while angiogenesis and inflammation were moderately improved in favor of wound healing in the andro injected rats (2.5 & 3.7 respectively) compared to saline-injected rats (3 & 4 respectively). The results clearly suggested that, though the improvement due to andro injection was moderate, these observations might create an awareness regarding the wound healing property of andro. Further studies are required to optimize the dosage of andro to influence the molecular pathways in order to show a better wound healing activity.

Abstract
AlCu5MnCdVA alloys had high specific strength, good machining and fatigue properties, outstanding electroplating and excellent corrosion resistance. However, due to wide crystallization temperature range, it is hard to realize sequential solidification for AlCu5MnCdVA alloy by traditional casting process. Laser Powder Bed Fusion (L-PBF) has become one of the most promising technology in Metal Additive Manufacturing (MAM). In this study, L-PBF was employed to fabricate AlCu5MnCdVA parts, and both mesoscopic numerical element model and experimental printing were applied to study the feasibility of L-PBF Additive Manufacturing AlCu5MnCdVA alloy. Relative densities, phase analysis and micromorphology were investigated systematically by SEM, EDS and XRD. The laser process parameters window for AlCu5MnCdVA were obtained: volumetric energy density 41–51 J mm−3, laser power 230–240W, laser scanning speed 1200–1325 mm s−1. And the relative density of parts fabricated by L-PBF reached 96.1%. Besides, AlCu5MnCdVA alloy fabricated by L-PBF was mainly consist of α-Al, little other phase such as Al2Cu or Al2Mn3 was detected.

Published: September 2021

Abstract
Epoxy micro-nanocomposite specimens incorporated with 66 wt% of silica micro fillers and 0.7 wt% of ion trapping particles as nano fillers, are coated with four different variants of coal. The conductivity of the coal deposited samples is observed to be in direct correlation with the percentage carbon content present in the coal samples. The epoxy micro-nanocomposite specimens coated with different variants of coals were successfully classified by using Laser induced breakdown spectroscopy (LIBS) assisted by various machine learning techniques. It is noticed that the classification through Logistic regression method (LRM) has reflected a higher training as well as testing accuracy of 100% and 98%, respectively when compared to other machine learning methods.
Nitrogen deposition shows no consistent negative nor positive effect on the response of forest productivity to drought across European FLUXNET forest sites
Authors: van der Graaf S C , Janssen T A J , Erisman J W , Schaap M 
Published: September 2021

Abstract
Atmospheric reactive nitrogen (N) deposition is an important driver of carbon (C) sequestration in forest ecosystems. Previous studies have focused on N-C interactions in various ecosystems; however, relatively little is known about the impact of N deposition on ecosystem C cycling during climate extremes such as droughts. With the occurrence and severity of droughts likely to be exacerbated by climate change, N deposition—drought interactions remain one of the key uncertainties in process-based models to date. This study aims to contribute to the understanding of N deposition-drought dynamics on gross primary production (GPP) in European forest ecosystems. To do so, different soil water availability indicators (Standardized Precipitation Evapotranspiration Index (SPEI), soil volumetric water) and GPP measurements from European FLUXNET forest sites were used to quantify the response of forest GPP to drought. The computed drought responses of the forest GPP to drought were linked to modelled N deposition estimates for varying edaphic, physiological, and climatic conditions. Our result showed a differential response of forest ecosystems to the drought indicators. Although all FLUXNET forest sites showed a coherent dependence of GPP on N deposition, no consistent or significant N deposition effect on the response of forest GPP to drought could be isolated. The mean response of forest GPP to drought could be predicted for forests with Pinus trees as dominant species (R
2 = 0.85, RMSE = 8.1). After extracting the influence of the most prominent parameters (mean annual temperature and precipitation, forest age), however, the variability remained too large to significantly substantiate hypothesized N deposition effects. These results suggest that, while N deposition clearly affects forest productivity, N deposition is not a major nor consistent driver of forest productivity responses to drought in European forest ecosystems.
A framework for determining energy use in rural food delivery services: capturing system interdependencies through an agent-based discrete-event approach
Authors: Gee Isabella M , Faust Kasey M , Webber Michael E 
Published: September 2021

Abstract
Food e-commerce has seen significant growth over the past decade that accelerated after the onset of the COVID-19 pandemic. Last-mile transportation and logistics are widely considered the most expensive and least efficient portion of the supply chain and have multiple important energy trade-offs such as cargo capacity and consumer density. Last-mile transportation energy use in rural areas is underrepresented in the literature. This study proposes a hybrid agent-based and discrete event model framework for evaluating the last-mile transportation energy use of van- and car-based food delivery services in a rural community, based on meal-kit and grocery delivery operations, respectively. This framework quantifies last-mile energy use in rural areas, and is demonstrated here using a neighborhood outside of Austin, TX as an analytical testbed. The study focuses on the effects of consumer density, cargo limitations, and vehicle speed. For the conditions examined with this framework, diesel delivery vans use more total energy than passenger cars for the same trip, though a van delivering four orders uses less energy per-order than a car delivering one order. However, there are trade-offs between vehicle type and mileage, cargo capacity, route density, and speed that are particularly important for delivery services operating in rural areas. This framework can be used by service providers to assess route-specific trade-offs for each vehicle and gauge which is preferable for given operating conditions or to evaluate the energy, and thus also cost, impact of expanding their services to rural areas.

Knock down analysis reveals critical phases for specific oskar noncoding RNA functions during Drosophila oogenesis
Authors: Kenny Andrew , Morgan Miles B , Mohr Sabine , Macdonald Paul M 
Published: September 2021

Abstract
The oskar transcript, acting as a noncoding RNA, contributes to a diverse set of pathways in the Drosophila ovary, including karyosome formation, positioning of the microtubule organizing center (MTOC), integrity of certain ribonucleoprotein particles, control of nurse cell divisions, restriction of several proteins to the germline, and progression through oogenesis. How oskar mRNA acts to perform these functions remains unclear. Here, we use a knock down approach to identify the critical phases when oskar is required for three of these functions. The existing transgenic shRNA for removal of oskar mRNA in the germline targets a sequence overlapping a regulatory site bound by Bruno1 protein to confer translational repression, and was ineffective during oogenesis. Novel transgenic shRNAs targeting other sites were effective at strongly reducing oskar mRNA levels and reproducing phenotypes associated with the absence of the mRNA. Using GAL4 drivers active at different developmental stages of oogenesis, we found that early loss of oskar mRNA reproduced defects in karyosome formation and positioning of the MTOC, but not arrest of oogenesis. Loss of oskar mRNA at later stages was required to prevent progression through oogenesis. The noncoding function of oskar mRNA is thus required for more than a single event.
