semi-Traj2Graph Identifying Fine-Grained Driving Style With GPS Trajectory Data via Multi-Task Learning

Driving behaviour understanding is of vital importance in improving transportation safety and promoting the development of Intelligent Transportation Systems (ITS). As a long-standing research topic in driving behaviour analysis, driving style identification is non-trivial. Almost all previous studies emphasize the research on the granularity of an entire trip or a driver. Inspired by the fact that an aggressive driver may drive safely at some time. In this article, based on the widely available GPS trajectory big data that records the driving behaviours implicitly, we propose a multi-task learning (MTL) framework called semi-Traj2Graph to recognize the fine-grained driving styles in the temporal dimension accurately. The MTL framework can incorporate the learning capability of graph representation in extracting high-level and interpretable features regarding complex driving behaviours and semi-supervised in exploiting unlabelled data and reducing labelling effort. More specifically, in the graph representation learning, a multi-view graph is first built to capture a more complete view of driving behaviours from the raw GPS trajectory data, then graph convolutional neural networks (Graph-CNNs) are applied. In the semi-supervised learning, a pseudo-label labelling is adopted to make use of the unlabelled data. We evaluate the proposed framework extensively based on two taxi trajectory datasets collected from the city of Beijing and Chongqing, China, respectively. Experimental results show that semi-Traj2Graph outperforms compared to other baselines, achieving an overall accuracy of around 90 percent. We also implement the framework on users’ smartphones via the collaborative cloud-edge computation manner to demonstrate the system usability in real cases.
Three‐dimensional virtual VR technology in environmental art design

More and more diversified environmental art design, combined with advanced 3‐D virtual virtual reality (VR) technology, has made great contributions to the development of modern display design. The purpose of this study is to use the combination of modern technology and traditional art to realize the cohesion of traditional environmental art and promote the economic and cultural development of the city and society. This experiment uses 3D virtual reality virtual technology, which usually takes the form of wearing glasses. There's a screen in front of your eyes. The sound can be transmitted via speakers or acoustics, so that people have an exciting feeling. The application of virtual reality technology to environmental art must follow three principles: the principle of truth in content, the principle of application in form and the principle of the quantity checked. Taking into account the virtual environment art projection function and the degree of user appreciation and referring to the virtual implementation method evaluation indicator in reality, five indices are also formed, such as degree of interaction, degree of photography, degree of function, degree of use, and degree of extension. The experimental results show that the weights of fast and accurate indexes are 0.74 and 0.36, respectively. Virtual interaction technology presents unlimited possibilities, breaks through the narrow nature of traditional display mode, opens up the current real exhibition development space, and provides new thinking for the design of environmental art.
The Targeted “Solution” in the Spotlight: How a Product Focus Influences Collective Action Within and Beyond Cross-Sector Partnerships

Based on a comparative case study of six cross-sector partnerships (CSPs) in global health, we illustrate how a CSP’s aim to address a social issue on the basis of products influences the governance of collective action within the partnership and beyond, at the field level. We show how such product focus, through specialization, influences a CSP’s structures and interaction culture and, as a reflection of the partners’ underlying logics, generates different CSP-field effects. Specifically, if conceived as self-contained and without considering the implications for other field players and programs, a product focus may expedite collective action within the CSP, but spur fragmentation and disruption at the field level. Conversely, if designed to strengthen field capacity and integration at the product-field interlinkages, a product focus may take longer to form but helps avoid the above field effects. On this basis, we advance theory on CSPs’ product focus as a multilevel coordination mechanism and elaborate on the implications for designing product-based CSPs.
Reported benefits of a Fit to Be Tied premarital mentorship program

ABSTRACT The present study explored reported benefits that students related regarding a Fit to be Tied premarital program. Seventeen participants discussed their respective experiences in the context of semi-structured interviews as part of a phenomenological, qualitative research study. Noted benefits included (1) feeling connections with marriage mentors (with sub-themes being the provision of an outside perspective, modeling, and benefits drawn from mentors’ insights) and (2) the most commonly noted benefits (with sub-themes being “addressing important issues” and “communication is key,” quotes inserted). Overall, couples expressed optimism regarding their future marital relationships being potentially more secure as a result of having learned about the areas where they may agree or disagree in marriage. The results are discussed in the context of the preeminence that the participants placed on the construct of relationship, the gateway hypothesis, the potential that the sample represented a self-selected biased group of students, and what the participants in the study did not indicate as being one of the study’s themes.
Quantum simulation of the Unruh effect with a Rydberg-dressed Bose-Einstein condensate

We propose a scheme for investigating the Unruh effect, i.e., the thermal radiation observed by uniformly accelerating observers or detectors, with ultracold atoms coupled by an off-resonant laser. We find that periodic modulation of the Rydberg-dressing interaction between atoms plays a significant role in the manipulation of a thermal bath in a uniformly accelerating reference frame. Our calculations show that the resulting Unruh temperature strongly depends on the driving frequency of the modulated Rydberg-dressing potential and the soft-core nature of the dressing interaction, i.e., the soft-core radius and height. These results reveal the potential applications of ultracold atoms with controllable long-range interaction in a wide variety of analog gravity phenomena.
Understanding each other's models: a standard representation of
global water models to support improvement, intercomparison, and
communication

Abstract. Global water models (GWMs) simulate the terrestrial water cycle, on the global scale, and are used to assess the impacts of climate change on freshwater systems. GWMs are developed within different modeling frameworks and consider different underlying hydrological processes, leading to varied model structures. Furthermore, the equations used to describe various processes take different forms and are generally accessible only from within the individual model codes. These factors have hindered a holistic and detailed understanding of how different models operate, yet such an understanding is crucial for explaining the results of model evaluation studies, understanding inter-model differences in their simulations, and identifying areas for future model development. This study provides a comprehensive overview of how state-of-the-art GWMs are designed. We analyze water storage compartments, water flows, and human water use sectors included in 16 GWMs that provide simulations for the Inter-Sectoral Impact Model Intercomparison Project phase 2b (ISIMIP2b). We develop a standard writing style for the model equations to further enhance model improvement, intercomparison, and communication. In this study, WaterGAP2 used the highest number of water storage compartments, 11, and CWatM used 10 compartments. Seven models used six compartments, while three models (JULES-W1, Mac-PDM.20, and VIC) used the lowest number, three compartments. WaterGAP2 simulates five human water use sectors, while four models (CLM4.5, CLM5.0, LPJmL, and MPI-HM) simulate only water used by humans for the irrigation sector. We conclude that even though hydrologic processes are often based on similar equations, in the end, these equations have been adjusted or have used different values for specific parameters or specific variables. Our results highlight that the predictive uncertainty of GWMs can be reduced through improvements of the existing hydrologic processes, implementation of new processes in the models, and high-quality input data.
Change in γ-glutamyl transpeptidase activity as a useful tool in identifying a group of patients with elevated risk of hepatocellular carcinoma development after DAA treatment of chronic hepatitis C

Aim of the study Hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) incidence will be diminishing due to use of direct acting antiviral agents (DAA), but there is still constant risk for HCC development. Elevated serum g-glutamyl transpeptidase (GGT) activity is associated with increased risk of liver cancer. In our study we tried to determine whether change in GGT activity may be useful in identifying patients with elevated risk of HCC development after DAA treatment. Material and methods The study population consisted of 111 patients with chronic hepatitis C (CHC) treated with DAA. Laboratory tests [alanine aminotransferase (ALT), GGT, a-fetoprotein (AFP)] and liver stiffness measurement (using FibroScan) were performed at the beginning and at the end of therapy. Results Pre-treatment ALT activity, GGT activity and AFP concentration in patients with CHC were directly associated with the stage of liver fibrosis. Elimination of HCV after DAA treatment caused significant reduction in serum GGT activity and was not associated with pre-treatment liver fibrosis. AFP concentration was significantly lower after treatment. It was observed regardless of pre-treatment AFP concentration, but the largest reduction was demonstrated in the group of patients with advanced fibrosis. In multivariate analysis there was no significant difference in GGT activity after treatment only in patients with pre-treatment normal AFP concentration and advanced liver fibrosis. Conclusions Patients who after achieving a sustained virological response (SVR) did not lower both AFP concentration and GGT activity may have higher risk of HCC development. Special monitoring may be required in patients with advanced liver fibrosis and normal AFP concentration before treatment.
Climbing Ropes—Environmental Hotspots in Their Life Cycle and Potentials for Optimization

This paper examines the environmental impacts of climbing ropes using life cycle assessment (LCA). An online survey was conducted to evaluate users’ behaviour and the potential of an open loop recycling project for old ropes. The results of the LCA study show that the production of the base material, polyamide 6, has, at 50%, the highest impact on the total global warming potential of 46.6 kg CO2-eq. per climbing rope and on most of the other environmental issues. At present, there is no practical alternative for a base material. However, the survey indicated a high willingness of climbers to return their ropes for the purpose of recycling. If all old ropes stored at home or being used for non-climbing purposes in Switzerland were to be recycled, 1170 t CO2-eq. could be saved by substituting primary material and avoiding waste incineration.
Mathematical model of a milking machine manipulator based on stepper motors

The automation of agriculture increases labour productivity and contributes to an increase in the output of agricultural products, an increase in their quality. These processes are closely related to the application of industrial production technology in agriculture, the improvement of planning and management. Also, the improvement of product quality and the growth of labour productivity are associated with the development of automated control systems that contribute to the autonomous operation of entire agricultural complexes. This paper deals with the development of a mathematical model of a milking installation based on stepper motors. The authors of the work recreated the operation of the milking installation, taking into account the operation of the kinematic scheme of the robot and the dynamics of the stepping motors, positioning of its working body near the tops of the teats of the udder of the animal, which are automatically recognized using image analysis from the 3D TOF camera. The uniqueness of this model lies in the fact that various stages of the operation of an autonomous milking installation are concentrated in one software product. This technology makes it possible to study the effect of each stage separately on the static positioning error of the manipulator working body. The model has been tested, an acceptable accuracy of the results of the model operation is achieved. This model can be recommended for use for engineering calculations and the development of control algorithms for the movement of the working body of the manipulator.
Method for numerical optimization of the parameters of regulator from unstable condition

The task of selecting the values of coefficients for a given controller structure from the initial unstable position is considered using the methods of numerical optimization. A method is proposed which consists in correcting the error function which is used for optimization. The main idea is multiplication by the exponent in the degree of the simulation step which the convergence of the transition process is achieved. After reaching convergence, you can perform numerical optimization. It is recommended to reduce the value of the exponent so that the figure of the transition process remains convergent. Further, when a stable transition process is reached, the value of the exponent should be zeroed out and then the optimization procedure for the error of the transition process should be performed without adjusting it until the change in the value of the objective function changes less than the specified threshold value. An example of such optimization is considered on the example of the transfer function of a second order oscillator.
Planar Dual-Polarization Bidirectional Multibeam Array Antenna for Millimeter-Wave Applications

A millimeter-wave (mm-wave) dual-polarization bidirectional multibeam array antenna based on substrate integrated waveguide (SIW) technology is presented in this article, which can generate 16 bidirectional radiation beams with two orthogonal linear polarizations. The proposed dual-polarization bidirectional multibeam array antenna, based on a new configuration, consists of two transverse slot array antennas (TSAAs), two longitudinal slot array antennas (LSAAs), and two dual-layer <inline-formula> <tex-math notation="LaTeX">$8 \times 8$ </tex-math></inline-formula> Butler matrices (BMs). To realize dual polarizations, a new type of TSAA is designed and combined with a conventional LSAA. For the purpose of bidirectional radiation, two types of dual-polarization array antenna (DPAA), which are realized by combining different arrangements of the TSAA and the LSAA, is composited. In addition, a dual-layer <inline-formula> <tex-math notation="LaTeX">$8 \times 8$ </tex-math></inline-formula> BM is developed, which can excite both the TSAA and the LSAA and generate dual-polarization bidirectional multibeam. Finally, the prototype of the planar dual-polarization bidirectional multibeam array antenna is fabricated, measured, and discussed. The measured results satisfactorily validate the simulated results.
Early Bone Metastases are Associated with Worse Outcomes in Metastatic Urothelial Carcinoma

BACKGROUND: Outcomes of patients with metastatic urothelial carcinoma (mUC) with early bone metastases (eBM) vs no early bone metastases (nBM) have not thoroughly been described in the age of immuno-oncology. OBJECTIVE: To compare survival and other clinical outcomes in patients with eBM and nBM. METHODS: We used a multi-institutional database of patients with mUC treated with systemic therapy. Demographic, metastatic site, treatment patterns, and clinical outcomes were recorded. Wilcoxon rank-sum, chi-square tests were performed. Survival was estimated by Kaplan-Meier method; multivariable Cox analysis was performed. 1Present address: Medical College of Wisconsin, Division of Hematology & Oncology, 8800 W Doyne Ave, Milwaukee, WI 53226, USA. 2Present address: University of Pittsburg Medical Center, Department of Medicine, 3459 Fifth Ave, Pittsburgh, PA 15213, USA. ∗Correspondence to: Christopher J.

Nelson et al. / Early Bone Metastases in Bladder Cancer RESULTS: We identified 270 pts, 67% men, mean age 69 ± 11 years. At metastatic diagnosis, 27% had ≥ 1 eBM and were more likely to have de novo vs. recurrent metastases (42% vs 19%, p < 0.001). Patients with eBM had shorter overall survival (OS) vs. those with nBM, (6.1 vs 13.7 months, p < 0.0001). On multivariable analysis, eBM independently associated with higher risk of death, HR = 2.52 (95% CI: 1.75–3.63, p < 0.0001). OS was shorter for patients with eBM who received initial immune checkpoint inhibitor vs platinum-based chemotherapy, (1.6 vs 9.1 months, p = 0.02). Patients with eBM received higher opioid analgesic doses compared to patients with nBM and received quantitatively more palliative radiation. CONCLUSIONS: Patients with mUC and eBM have poorer outcomes, may benefit less from anti-PD-1/PD-L1 therapy and represent an unmet need for novel therapeutic interventions. Dedicated clinical trials, biomarker validation to assist in patient selection, as well as consensus on reporting of non-measurable disease are required.
Identifying the Correct Host–Guest Combination To Sensitize Trivalent Lanthanide (Guest) Luminescence: Titanium Dioxide Nanoparticles as a Model Host System

This work develops a rationale for effective sensitization of trivalent lanthanide cation (Ln3+) luminescence in a semiconductor nanoparticle by examining the luminescence characteristics of Ln3+ dopants in titanium dioxide nanoparticles [Ti(Ln)O2] [Ln = praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), or ytterbium (Yb)], as a representative model system. For excitation of the TiO2 host at 350 nm the intraconfigurational 4f–4f sharp luminescence bands are observed for the Nd, Sm, Eu, Ho, Er, Tm, and Yb incorporated (doped) nanoparticles, and no such luminescence is observed for the Pr, Gd, Tb, and Dy containing nanoparticles. While host sensitized luminescence of lanthanide ions dominate the emission in the Nd and Sm incorporated nanoparticles, the host sensitization effect is less pronounced for the Eu and Yb containing systems, and for the Ho, Er, and Tm doped nanocrystals only a subset of the dopant.
Magnitude and Factors Associated With Uncontrolled Asthma Among Patients at Government Hospitals Follow-Up Clinic in Harar and Dire Dawa, Eastern Ethiopia.

Background: Uncontrolled asthma adds to the burden of non-communicable diseases. The studies on the level of asthma control in Ethiopia are confined to some specific geographical areas, didn’t assess trigger related factors and factors associated with partially and poorly controlled asthma separately and done with small sample sizes. The purpose of this study is to assess the magnitude and factors associated with uncontrolled asthma among patients at government hospitals follow-up clinic in Harar and Dire Dawa, Eastern Ethiopia.Methods: An institutional based cross-sectional study was conducted on selected 509 adult asthmatic patients on follow up at 6 government hospitals in Harar and Dire Dawa cities from February 21- April 20, 2020. Multinomial logistic regression has been used to identify factors associated with uncontrolled asthma and the result was presented using COR and AOR with their corresponding 95% confidence interval. Result: The magnitude of uncontrolled (poorly controlled and partially controlled) asthma was 420 (82.5%). Poor knowledge about asthma (AOR: 5.442; 95% CI (1.839-16.101)), negative attitude towards asthma (AOR=4.247; 95% CI (1.594-11.312)), non-adherence to medications (AOR=4.692; 95% CI (1.554-14.17)) and using the combination of Inhaled Corticosteroid (ICS) and Long Acting Beta2 Agonist (LABA) to control asthma (AOR=0.287; 95% CI (0.102-0.803)) were significantly associated with poorly controlled asthma. Average knowledge about asthma (AOR=3.918; 95% CI (1.276-12.03)) and using the combination of ICS and LABA (AOR=0.283; 95% CI (0.084-0.947)) were significantly associated with partially controlled asthma.Conclusion: This study indicated a higher magnitude of uncontrolled asthma. Poor and average knowledge about asthma, negative attitude towards asthma, non-adherence to medications, and using the combination of ICS and LABA to control asthma were associated with uncontrolled asthma. Health care providers, hospitals, health policymakers, and researchers should work on asthma control by different methods through enhancing patients' knowledge and attitude towards asthma.
Features of Propaganda and Manipulation in the Modern Information Space of New Media

This article discusses propaganda and manipulation as social phenomena and explores the features of its manifestations in the new media. The phenomenon of propaganda has been a recurrent topic of debate in public spaces over the past decades; there are dozens of international studies on the problems of its harm and necessity. The information environment constantly raises questions about the objectivity and reliability of the data distributed by the media, and their impact on public opinion and sociopolitical events in the world. With the development of communication technologies and the advent of new media, propaganda and manipulation reach a new level, gaining tremendous opportunities for influencing the individual and society. However, there is still no effective system of interaction with similar phenomena. Under the influence of constant informational impact in society, the system of values is rapidly changing and there is a reassessment of the main social constructs. The state, the sphere of education and the social sphere are need of new approaches to interacting with information and a changing society. The aims of the study are to identify the views of Russian youth regarding the current government and its policies, as well as determine the level of radicalism and protest potential of youth. This research discusses some propaganda technologies, especially relevant today. Examples of positive and negative propaganda are highlighted. Their specificity is substantiated and specific examples of such an impact are given, which entail significant socio-political events. The results of an empirical study have revealed mechanisms of the media influence on the individuals. The study has fixed the problem of radical political views formation, under the influence of the information environment created by new media. The necessity of creating an effective system to counter these phenomena in all spheres of social activity is substantiated. The problems and the direction requiring further research are formulated.
