Exploring unsafe sexual practices among truck drivers at Meerut District, India: a cross-sectional study

Background Despite implementation of HIV prevention programmes for truck drivers in India, unsafe sex behavior among truck drivers has been documented. Objective The objective of this study was to assess knowledge about HIV Transmission and modes of prevention, pattern of condom use with high risk partners and explore the practice of unsafe sex and its risk factors among truck drivers. Methods This exploratory cross-sectional study design was conducted on a recruited convenient sample of 100 truck drivers above 18 years from March to May 2015. Binary logistic regression was used to compute unadjusted odds ratio [95% Confidence Interval] for establishing association of risk factors with unsafe sex. Results Overall, only 7% had complete knowledge about HIV/AIDS transmission and prevention. 54% of truck drivers have sex with a high risk partner (commercial sexual worker or men having sex with men) and thirty-eight percent reported unsafe sexual practices due to inconsistent condom use with them. The various risk factors found significantly associated with unsafe sex were mean age of first intercourse (OR= 0.92, 95% CI: 0.75 – 0.97), access to pornography (OR = 4.4, 95% CI: 1.8 – 10.7) and conuming psychoactive substance before sex (OR = 4.06, 95% CI: 1.09 – 15.02). Conclusion Socio-demographic, occupational factors, pornography access and consuming psychoactive substances seems to influence the sexual behaviour of truckers.
Outdoor Mobile Mapping and AI-Based 3D Object Detection with Low-Cost RGB-D Cameras: The Use Case of On-Street Parking Statistics

A successful application of low-cost 3D cameras in combination with artificial intelligence (AI)-based 3D object detection algorithms to outdoor mobile mapping would offer great potential for numerous mapping, asset inventory, and change detection tasks in the context of smart cities. This paper presents a mobile mapping system mounted on an electric tricycle and a procedure for creating on-street parking statistics, which allow government agencies and policy makers to verify and adjust parking policies in different city districts. Our method combines georeferenced red-green-blue-depth (RGB-D) imagery from two low-cost 3D cameras with state-of-the-art 3D object detection algorithms for extracting and mapping parked vehicles. Our investigations demonstrate the suitability of the latest generation of low-cost 3D cameras for real-world outdoor applications with respect to supported ranges, depth measurement accuracy, and robustness under varying lighting conditions. In an evaluation of suitable algorithms for detecting vehicles in the noisy and often incomplete 3D point clouds from RGB-D cameras, the 3D object detection network PointRCNN, which extends region-based convolutional neural networks (R-CNNs) to 3D point clouds, clearly outperformed all other candidates. The results of a mapping mission with 313 parking spaces show that our method is capable of reliably detecting parked cars with a precision of 100% and a recall of 97%. It can be applied to unslotted and slotted parking and different parking types including parallel, perpendicular, and angle parking.
WeCo-SLAM: Wearable Cooperative SLAM System for Real-Time Indoor Localization Under Challenging Conditions

Real-time globally consistent GPS tracking is critical for an accurate localization and is crucial for applications such as autonomous navigation or multi-robot mapping. However, under challenging environment conditions such as indoor/outdoor transitions, GPS signals are partially available or not consistent over time. In this paper, a real-time tracking system for continuously locating emergency response agents in challenging conditions is presented. A cooperative localization method based on Laser-Visual-Inertial (LVI) and GPS sensors is achieved by communicating optimization events between a LiDAR-Inertial-SLAM (LI-SLAM) and Visual-Inertial-SLAM (VI-SLAM) that operate simultaneously. The estimation of the pose assisted by multiple SLAM approaches provides the GPS localization of the agent when a stand-alone GPS fails. The system has been tested under the terms of the MALIN Challenge, which aims to globally localize agents across outdoor and indoor environments under challenging conditions (such as smoked rooms, stairs, indoor/outdoor transitions, repetitive patterns, extreme lighting changes) where it is well known that a stand-alone SLAM will not be enough to maintaining the localization. The system achieved Absolute Trajectory Error of 0.48%, with a pose update rate between 15 and 20 Hz. Furthermore, the system is able to build a global consistent 3D LiDAR Map that is post-processed to create a 3D reconstruction at different level of details.
Fast Detection for Cyber Threats in Electric Vehicle Traction Motor Drives

While cyber-physical security of electric vehicles (EVs) is gaining increased concerns due to the fast development of vehicle onboard communication networks, the existing literature focuses on the vehicle level and it does not explicitly address cyber-threat detection for the EV powertrain traction motor drives. Therefore, in this article, we propose a fast, model-free approach to detect cyber threats in EV traction motor drives with only four easy-to-get, trustworthy sensor signals. First, the trustworthy motor current signals are selected to undermine the impacts of the vehicle’s random driving cycles. Then, a set of innovative time-domain current features that are the most sensitive to a wide range of anomalies are selected to reduce the number of observations needed, thus vastly reducing the computational burden and the time-to-detect. Next, four binary classifiers are developed to detect cyber threats, while a majority vote mechanism is adopted to reduce the false alarm rate. Finally, the proposed method is validated by the real-time hardware-in-the-loop simulations. Validation results show that the proposed detection method achieves much faster detection compared with traditional current signature analysis (CSA). Furthermore, the proposed detection methods achieve an accuracy higher than 98% with the false alarm rate less than 0.01%.
Non-penalty Regulations and Corporate Risk-taking：Evidence from Financial Report Inquiry Letters

In recent years, the securities market supervision system of China has gradually diversified, and the non-penalty regulations represented by inquiry letters have attracted more attention. With the increasing frequency of non-penalty regulations, inquiry letters gradually come into the public view, and the relevant media reports are also increasing. The current academic research on China’s securities supervision mainly focuses on penalty regulations, and less on non-penalty regulations. Although some studies have explored the economic consequences of inquiry letters, and found that non-penalty regulations improve the quality of auditing and the accuracy of performance forecast, and reduce the risk of stock price crash, whether the inquiry letters can truly play a regulatory role remains to be further explored.Under this condition, using the panel data of A-share listed companies from 2013 to 2017, this paper tests the effectiveness of inquiry letters from the perspective of corporate risk-taking. The results show that after receiving financial report inquiry letters, the level of corporate risk-taking is significantly increased; the more the total number (times) of financial report inquiry letters, the more inquiries contained in inquiry letters, and the more the total number of reply announcements, the stronger the promotion effect on corporate risk-taking. Meanwhile, the characteristics of inquiry letters will also affect the promotion of corporate risk-taking. Furthermore, we find that state-owned property rights and political connections are not conducive to the regulatory role of inquiry letters, inquiry letter regulation improves the level of corporate risk-taking by alleviating the agency problem between shareholders and the management, and inquiry letters significantly improve investment efficiency.This paper makes several contributions: Firstly, it makes complement to the relevant literature of non-penalty regulations by testing the economic consequences of inquiry letters in the new viewpoint of risk-taking. Secondly, it also enriches the studies of risk-taking behaviors, as the existing studies mainly focus on the internal and external environment. Thirdly, it has practical contributions by providing empirical evidence to affirm the effectiveness of non-penalty regulation methods, which helps to respond to the call of “innovating regulatory methods” proposed by the Report of the 19th National Congress of the Communist Party of China.
Mughal Men’s Head Ornaments with an Emphasize on Turban Ornaments and their Connection with European Aigrette

Jewelry is main aspect of dressing and Mughal Jewelry is a fascinating theme to explore. Its styles can be traced through the paintings that clearly give accurate information of the style and variety of ornaments that were used during the seventeenth and eighteenth centuries. Jewelry is considered the feminine adornment part but miniature shows the beautiful ornamentation of Mughal emperors also with variation in sizes and design. This article discusses the Mughal male head ornaments and study is focused on the turban ornamentations. As man’s turban is his sacrosanct property and variety of turban ornaments were used by Mughals. This paper is an attempt to understand and examine that how the Mughal turban ornament develops from simple feather to piece of complex jewelry designs and how other culture helps in its development. Why Mughal emperors worn such gemstones in headdress and which techniques were used for its decoration? Is there any specific reason of using such gemstones or just for ornamentations purposes? In the end it concludes that sarpech shapes helps in the development of European aigrette and became a part of European jewelry that later helped in the modification of turban ornaments and Euro-Indian sarpech-aigrette appeared with more delicate style.
Fatty liver index and hypertension-mediated organ damage in never-treated hypertensive patients without diabetes mellitus

Supplemental Digital Content is available in the text Background: We investigated whether fatty liver index (FLI), a surrogate marker of nonalcoholic fatty liver disease (NAFLD), is associated with hypertension-mediated organ damage (HMOD) in never-treated hypertensive patients without diabetes mellitus. Methods: We performed both clinic and ambulatory blood pressure (BP) measurements, and calculated the FLI for all participants. A FLI of no less than 60 indicates a high-risk of underlying NAFLD, whereas a FLI of less than 60 indicates lower risk. We evaluated left ventricular mass (LVM) by echocardiography, arterial stiffness by carotid--femoral pulse wave velocity (PWV), capillary rarefaction by nailfold capillaroscopy, as well as urinary albumin-to-creatinine ratio (ACR). HMOD was defined according to the categorical thresholds for each domain, except for capillary rarefaction in which case the categorization of patients was made by the median. Results: We included 146 hypertensive patients (men, 43.8%; mean age, 56.6 ± 10.8 years; BMI, 30.3 ± 4.9 kg/m2; FLI, 57.2 ± 27.7; office, systolic/diastolic, and 24-h BP, 153.5 ± 15.8/94.7 ± 9.8 mmHg, and 140.5 ± 9.9/83.8 ± 9 mmHg, respectively). Patients with FLI at least 60 (n = 76) were younger, with higher BMI and 24-h SBP, compared with patients with FLI less than 60 (n = 70). FLI was associated with HMOD after adjustment (LVM indexed to height, P = 0.004; PWV, P = 0.047; reduced capillary density, P = 0.001; and logACR, P = 0.003). High-risk FLI phenotype and FLI z scores increased the likelihood of any HMOD by 3.8 (95% confidence interval, 1.6–7.1) and 5.4 (95% confidence interval, 2.3–15.0) times, respectively. However, the increased number of HMOD domains has progressively stopped being determined by the FLI z scores (P = 0.65). Conclusion: High-risk FLI pattern was associated with various HMOD, and may re-classify never-treated hypertensive patients without diabetes mellitus into a higher cardiovascular risk level.
The Topic of the Ideal Dairy Farm Can Inspire How to Assess Knowledge about Dairy Production Processes: A Case Study with Students and Their Contributions

The dairy farm and on-farm production processes are the subject of numerous evaluations. These are not only evaluations of the economic efficiency of milk production. Opinions expressed by various social groups are also an important contribution to improving the approach to milk production on the farm. As a result of such opinions, a vision of an ideal dairy farm may be formed. The aim of the study was to develop the thematic area of an ideal dairy farm in the opinion of two groups of students who were learning remotely (in the distance learning system) due to the Covid-19 pandemic. The first group consisted of six Erasmus+ students. The second group consisted of 70 full-time Polish students. As part of their homework, the students answered three questions about the ideal dairy farm. Students had 4 weeks to do their homework. Erasmus+ students’ homework was used to propose a ranking method for assessing the answers to three questions by the students themselves. Homework of Polish students was used to analyze the frequency of using certain keywords. Polish students, in their homework on the ideal dairy farm, mainly used the basic concepts related to dairy production. Unfortunately, a very small number of students used terms that represent a responsible approach to dairy production, including ethical aspects, freedom, sustainability, animal pain, antibiotics, and organic milk production. In conclusion, it was indicated that the curriculum should be structured in such a way as to raise students’ awareness of dairy production and its current challenges.

Investigation into Effect of Natural Shellac on the Bonding Strength of Magnesium Substituted Hydroxyapatite Coatings Developed on Ti6Al4V Substrates

The bioactive and biocompatible properties of hydroxyapatite (HA) promote the osseointegration process. To enhance other bio-functions of HA such as improving the antibacterial property of the implant, increasing the rate of cell proliferation, or improving tissue generation capability, HA is substituted with many elements such as Zn, Cl, Ba, Fe, Cu, Ag, Sr, F, Na, etc. This study reports development of Magnesium substituted HA (Mg-HA) coatings on Ti6Al4V substrates using the dip coating technique. To improve the adhesion and stability of the coating, an intermediate layer of shellac was applied between the coating and Ti6Al4V substrate. The dip coating process parameters were optimized using the Taguchi technique and it was found that dipping time of 35 s and 13% w/w of shellac concentration provided the maximum bonding strength of 12.5 MPa. The biocompatibility, dissolution, and corrosion study of the developed coating using the optimal parameters obtained were carried out in this study. An improvement in cell growth and cell proliferation was observed in the extract medium prepared from coated substrates. Release of Ca, P and Mg ions from the surface of the coated substrate into the simulated body fluid (SBF) was found to be almost constant which shows the stability of the thin film coating formed. The Mg-HA coated substrate also exhibited better corrosion resistance than the uncoated substrate.
A 2233-Year Tree-Ring Chronology of Subarctic Black Spruce (Picea mariana): Growth Forms Response to Long-Term Climate Change

ABSTRACT We present the longest tree-ring chronology to date in northeastern North America (2233 years; 227 BCE – 2005 CE), resulting from several research projects conducted at the subarctic treeline in northern Quebec. This raw chronology of tree-ring width includes 464 black spruce (Picea mariana (Mill.) B.S.P.) shrubs (krummholz) growing in wetlands and preserved within peatlands. An indexed series of 152 erect black spruce trees that have lived in wetlands is also presented, covering the period 216 BCE to 1619 CE. We compared these chronologies to a tree-ring series including 116 black spruce trees and krummholz having grown on well-drained lichen woodlands over the period 1304–2000 CE. These chronologies highlight the major climatic periods of the last two millennia. Floating chronologies dating from 2500 to 3500 years ago were also developed from trees preserved in frozen peat. Growth rings from this period are much wider than those of the last 2233 years, suggesting warm climatic conditions and permafrost-free peatlands during the transition from mid- to late Holocene. The three subarctic chronologies presented here underscore the relevance and usefulness of tree growth rings and growth forms as ecological tools to assess the influence of climate on subarctic ecosystems.
Optimal design of aspheric acoustic lens based on ray tracing

As a new non-destructive imaging technology in the field of biomedicine, photoacoustic imaging technology combines the advantages of pure optical and pure acoustic imaging with good spatial resolution, high sensitivity, and strong penetrating power. In the photoacoustic microscopy imaging system, the acousto-optic coupling prism is a component for optical transmission and ultrasonic detection. It is usually composed of an irregular prism and a spherical concave acoustic lens at the bottom. Because the spherical acoustic lens has a poor focusing effect on the ultrasonic beam, the accuracy of ultrasonic detection is low. In order to solve this problem, we propose an optimization method to eliminate the influence of acoustic lens on the beam transmission. A collimating lens is added to the acousto-optic coupling prism with an aspheric acoustic lens at the bottom of the system. In this paper, Zemax optimizes the curvature coefficient and thickness of the collimating lens to eliminate the deteriorating effect of the aspheric acoustic lens on the beam transmission, and evaluates the optimization effect by analyzing the spot and MTF image. The simulation results show that the collimating lens can eliminate the influence of the aspheric acoustic lens on the beam transmission, so that the optical focus and the acoustic focus can be kept coaxial and confocal, and the detection efficiency of the photoacoustic signal can be improved. This work has theoretical guiding significance for the study of photoacoustic microscopy imaging with large depth of field.
Repetitive transcranial magnetic stimulation promotes neural functional recovery via upregulation of synaptic plasticity-related proteins in rats with traumatic brain injury

Background Repetitive transcranial magnetic stimulation (rTMS) has become a popular approach for the treatment of traumatic brain injury (TBI). This study aimed to assess the efficacy and underlying mechanism of rTMS in TBI model rats. Methods Forty-five rats were randomized into SHAM, TBI, and rTMS (TBI and rTMS therapy) groups. Moderate TBI was established using Feeney's weight-dropping method. High-frequency rTMS (20 Hz) was administered to the damaged area in the rTMS group for two weeks. Neural function was assessed by modified neurological severity score (MNSS) at 3, 9, and 16 days after TBI. Synaptic ultrastructure was observed by transmission electron microscopy and levels of synaptic plasticity-related proteins (BDNF, TrkB, NMDAR1, P-CREB, and SYN) were assessed by immunohistochemistry, Western blotting, and real-time PCR. Results The rTMS group showed a lower MNSS than the TBI group at 16 days (P < 0.05). Compared to the TBI group, the postsynaptic density (PSD) was increased, the width of the synaptic cleft was decreased, and the synaptic active zone was lengthened in the rTMS group (all P < 0.05). Compared with the sham group, protein levels and mRNA expression of BDNF, TrkB, NMDAR1, and P-CREB were increased in the TBI group (P < 0.05) and further upregulated after rTMS treatment (P < 0.05). In addition, rTMS partially reversed downregulation of SYN (P < 0.05). Conclusions Taken together, these findings support that rTMS improves neural functional recovery in TBI rats. The possible mechanism is that rTMS modulates synaptic structural plasticity by reducing loss of SYN and alters synaptic functional plasticity by increasing cortical levels of BDNF, TrkB, NMDAR1, and P-CREB.
