The association of stress with sleep quality among medical students at King Abdulaziz University

Objective: This study aims to determine the prevalence and the association of stress with sleep quality among medical students at King Abdulaziz University (KAU), Jeddah, Saudi Arabia. Methods: A cross-sectional study was done among 326 medical students of KAU using a stratified random sampling technique. An electronic self-administered questionnaire was used. Kessler Psychological Distress Scale (K10) and Pittsburgh Sleep Quality Index (PSQI) were used to assess the stress and sleep quality, respectively. Results: The overall students who experienced stress were 65%. The prevalence of poor sleep quality (total PSQI score ≥5) was 76.4%. There was a strong association between stress and poor sleep quality (value of Cramer's V = 0.371, P < 0.001), and it showed that the increase in stress level is a significant predictor of poor sleep quality. Conclusion: A high prevalence of stress and poor sleep quality was found among the students and the study confirms a strong association between them. We recommend establishing courses focusing on educating the students about proper sleep hygiene and how to deal with the stressful environment.
CycleGAN using Semi-Supervised Learning

CycleGAN realizes unsupervised learning of image-to-image translation. However, the performance is inferior to the supervised learning model. In this paper, we apply Semi-Supervised Learning to CycleGAN. We show that using a few pair data in the photo ↔ label translation by the Cityscapes Dataset can dramatically improve the learning performance. We also show generalization performance from photo ↔ label tasks by CMP Facade Database and Google Map using the veriﬁed hyper parameters.
Green Organic Solvent-Free Oxidation of Alkylarenes with tert-Butyl Hydroperoxide Catalyzed by Water-Soluble Copper Complex

Abstract Different benzylic compounds were efficiently oxidized to the corresponding ketones with aqueous 70% tert-butyl hydroperoxide (TBHP) and the catalytic system composed of CuCl2.2H2O and 2,2’-biquinoline-4,4’-dicarboxylic acid dipotassium salt (BQC). The catalytic system CuCl2/BQC/TBHP allows obtaining high yields at room temperature under organic solvent-free conditions. The interest of this system lies in its cost effectiveness and its benign nature towards the environment. Benzylic tertbutylperoxy ethers and benzylic alcohols were observed and suggested as the reaction intermediates. Analysis of organic products by atomic absorption did not show any contamination with copper metal. In terms of efficiency, CuCl2/BQC system is comparable or superior to the most of the catalytic systems described in the literature and which are based on toxic organic solvent. Graphical Abstract
microRNA-204-5p Participates in Atherosclerosis Via Targeting MMP-9

Abstract The aim of the present study was to investigate the role and mechanism of microRNA-204-5p (miR-204-5p) in atherosclerosis (AS)-related abnormal human vascular smooth muscle cells (hVSMCs) function. Firstly, we analyzed the expression of miR-204-5p and found that the miR-204-5p expression level was clearly downregulated in atherosclerotic plaque tissues and blood samples compared to the normal controls. Then, matrix metallopeptidase-9 (MMP-9) was predicted to be the potential target of miR-204-5p by TargetScan and this prediction was confirmed by luciferase assays. Besides, we observed that miR-204-5p could negatively regulate the expression of MMP-9 in hVSMCs. Subsequently, Thiazolyl Blue Tetrazolium Bromide (MTT) assay, transwell assay and flow cytometry were performed to detect the proliferation, migration and apoptosis of hVSMCs. Down-expression of miR-204-5p led to the promotion of proliferation and migration accompanied with the suppression of apoptosis in hVSMCs, and these effects were reversed by MMP-9-siRNA. In addition, overexpressed miR-204-5p could inhibit hVSMC proliferation and migration and promote the apoptosis of hVSMCs. However, the effects were also abrogated by overexpressed MMP-9. Together, our findings showed that miR-204-5p plays an important role in the growth and migration of hVSMCs by targeting MMP-9, which might be a novel biomarker and promising therapeutic target for AS.
SEDE: Semantic Evolution-based Dynamic Knowledge Graph Embedding

Knowledge graph has recently attracted signiﬁcant interests due to its extensive applications. Triple facts in knowledge graph is not always valid in time dimension, e.g., the fact (The President of the United States is Barack Obama) is valid from 2008 to 2017. However, most knowledge graph embedding algorithms mainly focus on solving static knowledge graph embedding and are knotty to adapt to dynamic knowledge graph. In this paper, we propose a dynamic knowledge graph embedding model with semantic evolution. Our algorithm uses non-random initialization and smooth embedding drifting to map the knowledge graph embeddings into a common space, which makes embeddings able to inherit time information. The experimental results on temporal datasets prove our algorithm could process time information eﬀectively.

New tirapazamine derivatives protect cardiomyocytes from doxorubicin toxicity

Abstract Doxorubicin cardiotoxicity is caused by various mechanisms, most importantly by oxidative stress originating in the mitochondria. Tirapazamine is a hypoxia-activated anticancer experimental drug. Both drugs in normoxia conditions undergo univalent reduction, thus tirapazamine may compete with doxorubicin in univalent reduction enzyme uptake. Herein, tirapazamine derivatives consisted of drug molecules and alkyl chain-connected triphenylphosphine cations that bring about an accumulation in mitochondria. The aim of this study was to evaluate the interaction of newly synthesized tirapazamine derivatives with doxorubicin in rat cardiomyocytes via an vitro model. In the work, H9C2 cells were incubated with combinations of doxorubicin, tirapazamine and seven variants of tirapazamine derivatives. After 24 hours, cell viability was assessed using MTT assay and the results were confirmed by microscopic observation. Tirapazamine in all tested concentrations did not revealed significant protective activity to cardiomyocytes treated with doxorubicine. However, tirapazamine derivatives diminished the cytotoxic effect of doxorubicin regardless of concentration and alkyl chain length. Tirapazamine derivatives have shown protective effects in relation to cardiomyocytes treated with doxorubicin and the mechanism of this phenomenon must be confirmed.
The Dilemmas of Rural Planning and Planners in Oyo State, Nigeria

Abstract The focus on urban planning continues to flood the global literature. However, there is continued silence and neglect with regard to rural planning. The study examined the state of rural planning in Oyo State, Nigeria. Primary data was sourced using structured questionnaires and in-depth interviews. Questionnaires were administered to two hundred and fifty (250) rural households in six (6) rural local government areas (LGAs) of Oyo State. It was revealed that rural areas remain neglected and behind in planning activities. A majority of respondents believe that no planning takes place in the rural communities in which they reside. The study concludes that improved communication on planning issues between the tiers of the bureau of physical planning and urban development offices remains the route to effective planning. Improved capacity building (expertise) and training are suggested for rural planners. It is also suggested that understanding the local culture is important in contributing towards effective and responsive rural planning.
Residents as teachers: optimizing the benefit of a difficult airway management simulation session

Abstract Background Simulation is widely used in airway management training. Objectives To show that assigning anesthesia residents’ simulation educator roles improved cognitive learning outcomes. Methods Postgraduate second- and third-year (PGY-2 and PGY-3) anesthesia residents were randomly assigned to three groups: a teacher group (T), a hot-seat (active participant) group (H), and an observer group (O). After a train-the-trainer session, the T group prepared simulation scenarios for difficult airway management and then conducted the simulation sessions and post-session debriefing. The H group participated in the scenarios, and the O group observed the sessions. All participants attended the post-session debriefing. Evaluation was conducted at pretest, immediate posttest, and 3 months (retention test). Score differentiation and average normalized gain were calculated. Participants completed a post-simulation class survey. Results Participants were 49 residents (PGY-2 = 24, PGY-3 = 25). The T group had the highest posttest score (17.06 ± 1.23); this score significantly differed from the O group (14.75 ± 2.57, P = 0.003) but not the H group (15.64 ± 1.54, P = 0.103). The average normalized gain was significantly higher in the T group than in the H and O groups (0.51 ± 0.22, 0.18 ± 0.32, and 0.17 ± 0.47, respectively; P = 0.012). Participants retained knowledge at 3 months after the session, with no significant differences among the groups. Most participants (45%) preferred to be active scenario participants, and 20% preferred to teach. Overall satisfaction was high in all groups. Conclusion This study showed that a teaching role can be effectively applied for residents in simulation-based education on difficult airway management to support better learning outcomes.
A Framework for Designing Business-Acceleration Programs: A Case Study from Egypt

Abstract Business acceleration services are gaining popularity around the world. In this study, we put forward a framework and an iterative process for the design of acceleration programs. Based on literature from around the world and a case study of an acceleration program in Egypt, we develop a model that considers the process for designing, monitoring, and adjusting an acceleration program based on both internal and external considerations. In this study, we find that aspects such as the analysis of the external environment in the surrounding entrepreneurship ecosystem, and of the internal environment in the host institution’s capabilities, resources, and limitations, are important in guiding the design process. We also illustrate a comprehensive set of design parameters to be considered in the development of the acceleration program, including the program’s value proposition, sector focus, duration, service offering, resource intensity, partnerships, as well as the profile of the startups supported. In presenting this model, we aim to fill an important gap in research on how accelerators are designed and offer a framework substantiated by academic review that helps practitioners and policymakers avoid “copying and pasting” acceleration programs without careful attention to the local contexts and needs.
Near infrared hyperspectral imaging-based approach for end-of-life flat monitors recycling

Abstract The technological innovation and the relentless marketing of new electronic products with improved performance generate increasing quantities of Waste from Electrical and Electronic Equipment (WEEE). In this scenario, End-Of-Life (EOL) flat monitors and screens represent a category generating, as a consequence of the rapid change in technology, an important amount of waste. Considering future estimations, the implementation of an adequate recycling infrastructure is necessary. An efficient, reliable and low-cost analytical tool is thus needed to perform detection/control actions in order to assess: i) waste composition and ii) physical-chemical attributes of the resulting materials. The knowledge of these information is a requirement to set-up and to implement correct recycling actions. In this study, a cascade identification approach, based on Near InfraRed (NIR) – HyperSpectral Imaging (HSI), was carried out. More in detail, a four-steps classification was designed, implemented and set-up in order to recognize different materials occurring in a specific WEEE stream: EOL milled monitors and flat screens. Adopting the proposed approach, different material categories are correctly recognized and classified. Obtained results can be useful not only to set-up a quality control system, but also to improve sorting actions in this specific recycling sector.
On finite series solutions of conformable time-fractional Cahn-Allen equation

Abstract The aim of this article is to derive new exact solutions of conformable time-fractional Cahn-Allen equation. We have achieved this aim by hyperbolic function and expa function methods with the aid of symbolic computation using Mathematica. This idea seems to be very easy to employ with reliable results. The time fractional Cahn-Allen equation is reduced to respective nonlinear ordinary differential equation of fractional order. Also, we have depicted graphically the constructed solutions.
Clinical Applications of Imaging Modalities of the Carpal Joint in Dogs with Particular Reference to the Carpal Canal

Abstract The structure of the canine carpal joint is complex. This small joint consists of articulations that include the antebrachiocarpal, middle, carpometacarpal, and intercarpal joint surfaces. A large number of ligaments and tendons support and stabilise the carpus in dogs. Many injuries of this joint in dogs are not correctly recognised, diagnosed, or treated due to the limited use of diagnostic imaging methods. Radiography, the most common of them, has extensive application in diagnosing the causes of lameness in small animals. Other techniques, such as ultrasonography, computed tomography, and magnetic resonance imaging visualise other joint structures and surrounding soft tissues. However, these imaging modalities are rarely used to diagnose diseases and injuries of the canine carpus at present. The main reason for this is the small amount of research carried out and the lack of a properly described methodology for the use of imaging techniques. The wide use of all diagnostic imaging tools in the diagnosis of diseases and injuries of the wrist joint in humans shows that conducting studies on dogs could expand current knowledge. The use of these techniques in veterinary medicine could facilitate diagnosis and subsequent therapy of carpal disorders in dogs. MRI is the most frequently used imaging method in human medicine for visualisation of abnormalities of joints. This method could become a valuable part of the detection of inflammatory, traumatic, and degenerative diseases of the carpal joint in dogs.
An Overview of the Carbonatites from the Indian Subcontinent

Abstract Carbonatites are carbonate-rich rocks of igneous origin. They form the magmas of their own that are generated in the deep mantle by low degrees of partial melting of carbonated peridotite or eclogite source rocks. They are known to occur since the Archaean times till recent, the activity showing gradual increase from older to younger times. They are commonly associated with alkaline rocks and be genetically related with them. They often induce metasomatic alteration in the country rocks forming an aureole of fenitization around them. They are host for economically important mineral deposits including rare metals and REE. They are commonly associated with the continental rifts, but are also common in the orogenic belts; but not known to occur in the intra-plate regions. The carbonatites are known to occur all over the globe, majority of the occurrences located in Africa, Fenno-Scandinavia, Karelian-Kola, Mongolia, China, Australia, South America and India. In the Indian Subcontinent carbonatites occur in India, Pakistan, Afghanistan and Sri Lanka; but so far not known to occur in Nepal, Bhutan, Bangladesh and Myanmar. This paper takes an overview of the carbonatite occurrences in the Indian Subcontinent in the light of recent data. The localities being discussed in detail cover a considerable time range (>2400 Ma to <0.6 Ma) from India (Hogenakal, Newania, Sevathur, Sung Valley, Sarnu-Dandali and Mundwara, and Amba Dongar), Pakistan (Permian Koga and Tertiary Pehsawar Plain Alkaline Complex which includes Loe Shilman, Sillai Patti, Jambil and Jawar), Afghanistan (Khanneshin) and Sri Lanka (Eppawala). This review provide the comprehensive information about geochemical characteristics and evolution of carbonatites in Indian Subcontinent with respect to space and time.
Morality, protection, security and gain: lessons from a minimalistic, economically inspired multi-agent model

Abstract In this work, we introduce a simple multi-agent simulation model with two roles of agents that correspond to moral and immoral attitudes. The model is given explicitly by a set of mathematical equations with continuous variables and is characterized by four parameters: morality, protection, and two efficiency parameters. Agents are free to adjust their roles to maximize individual gains. The model is analyzed theoretically to find conditions for its stability, i.e., the fractions of agents of both roles that lead to an equilibrium in their gains. A multi-agent simulation is also developed to verify the dynamics of the model for all values of morality and protection parameters, and to identify potential discrepancies with the theoretical analysis.
Cloning and Identification of PK15 Cells for Enhanced Replication of Classical Swine Fever Virus

Abstract Introduction Classical swine fever virus (CSFV) causes an economically important and highly contagious disease of pigs, leading to economic losses around the world. Attenuated live vaccines with CSFV antigens have played an important role in the prevention and control of the disease. Porcine kidney 15 (PK15) cells have been widely used for the propagation of CSFV, but this cell line is not efficient or homogeneously susceptible to viral infection. Material and Methods To achieve a homogeneous PK15 cell line which enabled high titre replication of CSFV, we used the limiting dilution cell cloning method. Results We developed two cell clones, PK15-1A6 and PK15-3B1, which respectively have high- and low-permissive phenotypes to CSFV infection. The PK15-1A6, PK15-3B1, and PK15 parent cells showed different characteristics in cell proliferation rate, susceptibility to CSFV infection, and CSFV production. The mean virus titres per millilitre reflected by TCID50 values in PK15-1A6, PK15-3B1, and PK15 parent cells were 106.85, 103.63, and 104.74, respectively. Conclusion The PK15-1A6 cell clone is more permissive to CSFV infection than the PK15 parent cells. The screened high-permissive cells will be useful for CSFV propagation and vaccine development in vitro, and facilitate research on the pathogenicity of CSFV.
Demographic implications of transiting from segregation to integration: a focus on education issues in Buffalo City, South Africa

Abstract The study aims at interrogating the transformation of education in Buffalo City following integration of East London with its black townships. This paper is largely framed from a quantitative paradigm that draws from statistical data in linking population changes with educational patterns in the study area. Census data was used to trace population changes in post-apartheid South Africa, while performance in education was informed by matriculation results. Quantitative data were complemented with key informants’ qualitative opinions. The results indicate that the quality of education in former “white” schools is better than that of “township” schools. There are several pull factors that attract township learners to former white schools, albeit with integration challenges. The study concludes that if these challenges are masked to education planners and policy makers, they militate against the envisioned liberalisation of the democratic education system.
Translocalization and Social Rescaling: Case Studies of Linguistic Landscapes in Guangzhou

Abstract Languages and linguistic resources transport from one locality to another, adapting to the norms, customs, and regulations of a new locality. This process involves translocalization. Translocalization emphasizes the movement of linguistic resources against the backdrop of globalization and the combination or reframing of resources from different localities. This research explores the extent to which translocalization is reflected by the linguistic landscapes of three distinct commercial areas in Guangzhou, China. It goes on to discuss how translocalization works together with social rescaling to incur the movement of linguistic resources and to result in distinct linguistic landscapes of the three commercial areas. It concludes that some languages or linguistic resources, such as English, pinyin and traditional Chinese writing, are transported to local contexts for the purpose of rescaling, whereas other languages or dialects, like Cantonese, might gradually lose their function of rescaling and retain its function in indexing local identity and solidarity. This study calls for more attention to the local resources and contexts in linguistic landscape studies. It argues for the indexical function of linguistic resources in social rescaling and city planning.
Method for the Machine-Generation of Ancient Chinese Poetry Based on a Deep Neural Network Combined with Images

The use of deep learning techniques to solve problems in the art world has become a challenge for researchers. This paper uses deep learning technology to study and analyze the generation of ancient Chinese poetry as an art form. The results of early methods have the following problems: the poems are not clear, the sentences are inconsistent, and the readability is not smooth. This paper proposes a method incorporating image features to automatically generate ancient Chinese poems. First, ResNet and long short-term memory are used to obtain the Chinese description from the given image feature. Then, the keywords from the Chinese description are extracted from the sentence containing the creative intent and combined into the keyword sequence and the pregeneration sequence. Finally, these sequences are used to constrain the length and duration of the memory network to generate ancient Chinese poetry. The proposed method is evaluated using a manual evaluation method. The poetry generated by our proposed method achieves good coherency, fluency, and meaning, resulting in a high average score, which indicates that our method is effective. Thus, the task of generating ancient Chinese poetry is accomplished.
