description: Modern Cloud/Edge architectures need to orchestrate multiple layers of heterogeneous computing nodes, including pervasive sensors/actuators, distributed Edge/Fog nodes, centralized data centers and quantum devices. The optimal assignment and scheduling of computation on the different nodes is a very difficult problem, with NP-hard complexity. In this paper, we explore the possibility of solving this problem with Variational Quantum Algorithms, which can become a viable alternative to classical algorithms in the near future. In particular, we compare the performances, in terms of success probability, of two algorithms, i.e., Quantum Approximate Optimization Algorithm (QAOA) and Variational Quantum Eigensolver (VQE). The simulation experiments, performed for a set of simple problems, %CM230124 that involve a Cloud and two Edge nodes, show that the VQE algorithm ensures better performances when it is equipped with appropriate circuit \textit{ansatzes} that are able to restrict the search space. Moreover, experiments executed on real quantum hardware show that the execution time, when increasing the size of the problem, grows much more slowly than the trend obtained with classical computation, which is known to be exponential.

description: Software Defined Networking (SDN) is driving transformations in Research and Education (R&E) networks, enabling innovations in network research, enhancing network performance, and providing security through a policy-driven network management framework. The Holland Computing Center (HCC) at the University of Nebraska-Lincoln (UNL) supports scientists studying large datasets, and has identified a need for flexibility in network management and security, particularly with respect to identifying data flows. This problem is addressed through the deployment of a production SDN with a focus on integrating network resource management for large-scale GridFTP data transfers. We propose SNAG (SDN-managed Network Architecture for GridFTP transfers), an architecture that enables the SDN-based network management of GridFTP file transfers for large-scale science datasets. We also show how SNAG can efficiently and securely identify science dataset transfers from projects such as Compact Muon Solenoid (CMS) and Laser Interferometer Gravitational-Wave Observatory (LIGO). We focus on exposing an Application Program Interface (API) between the trusted GridFTP process and the network layer allowing the network to track flows via application metadata.

description: To study the contamination of perfluoroalkyl acids (PFAAs) in Chinese food and the risk of dietary exposure for the Chinese population, the data of 17 PFAAs covering 38 cities throughout China in 15 groups of foods were collected for meta-analysis from published and available research literature. Using food consumption and body weight parameters, estimated dietary intakes (EDIs) were calculated for evaluation using the Scenario-Based Risk Assessment (SceBRA) modelling. Among food groups, the highest ΣPFAAs concentrations and EDI contributions were both found in poultry (363 ng/g), fish and shrimp (313 ng/g), dark vegetables (309 ng/g), fruits (116 ng/g) and pork (25 ng/g). The EDI of adults in the high-exposure scenario was about twice that of the intermediate-exposure scenario, while the EDI of children was about twice that of adults’ EDI in the intermediate-exposure scenario. In addition, the PFOS EDI for children under high exposure approached its tolerable daily intake (TDI). Therefore high dietary exposure to PFAAs is giving rise to an increased health risk, especially for children.

description: Introduction: Driving under the influence (DUI) citations are still a serious concern among drivers aged 16–20 years and have been shown to be related to increased risk of fatal and nonfatal crashes. A battery of laws and policies has been enacted to address this concern. Though numerous studies have evaluated these policies, there is still a need for comprehensive policy evaluations that take into account a variety of contextual factors. Previous effort by this research team examined the impact of 20 minimum legal drinking age–21 laws in the state of California, as they impacted alcohol-related crash rates among drivers under 21 years of age while at the same time accounting for alcohol and gas taxes, unemployment rates, sex distribution among drivers, and sobriety checkpoints. The current research seeks to expand this evaluation to the county level (San Diego County). More specifically, we evaluate the impact of measures subject to county control such as retail beverage service (RBS) laws and social host (SH) laws, as well as media coverage, city employment, alcohol outlet density, number of sworn officers, alcohol consumption, and taxation policies, to determine the most effective point of intervention for communities seeking to reduce underage DUI citations. Methods: Annual DUI citation data (2000 to 2013), RBS and SH policies, and city-wide demographic, economic, and environmental information were collected and applied to each of the 20 cities in San Diego County, California. A structural equation model was fit to estimate the relative contribution of the variables of interest to DUI citation rates. Results: Alcohol consumption and alcohol outlet density both demonstrated a significant increase in DUI rates, whereas RBS laws, SH laws, alcohol tax rates, media clusters, gas tax rates, and unemployment rates demonstrated significant decreases in DUI rates. Conclusions: At the county level, although RBS laws, SH laws, and media efforts were found to contribute to a significant reduction in DUI rates, the largest significant contributors to reducing DUI rates were alcohol and gas taxation rates. Policy makers interested in reducing DUI rates among teenagers should examine these variables within their specific communities and consider conducting community-specific research to determine the best way to do so. Future efforts should be made to develop models that represent specific communities who are interested in reducing DUI rates among drivers aged 16–20 years.

description: The excitation of quadratic quasinormal modes is an important nonlinear phenomenon for a Kerr black hole ringing at a specific linear mode. The amplitude of this second-order effect is proportional to the square of the linear mode amplitude, with the ratio being linked to the nature of the Kerr black hole. Focusing on the linear $(l=m=2,n=0)$ mode, we compute the dependency of the ratio on the dimensionless spin of the black hole, ranging up to 0.99, with the method applicable for more general mode couplings. Our calculation makes use of the frequency-domain, second-order Teukolsky equation, which involves two essential steps (a) analytically reconstructing the metric through the Chrzanowski-Cohen-Kegeles approach and (b) numerically solving the second-order Teukolsky equation using the shooting method along a complex contour. We find that the spin dependence of the ratio shows a strong correlation with the angular overlap between parent and child modes, providing qualitative insights into the origin of the dependence. Depending on the nature of the angular overlap, the ratio decreases with spin in scenarios such as the channel $(l=m=2,n=0)\times(l=m=2,n=0)\to(l=m=4)$ or increases in situations like $(l=m=2,n=0)\times(l=m=2,n=0)\to(l=5,m=4)$. For both cases, the ratios do not vanish in the extremal limit. As a byproduct, we find that the Weyl scalars can be concisely expressed with the Hertz potential.

description: ABSTRACT Malaysia has seen a high rate of economic growth in past couple of decades hand in hand with an ever increasing size of population. Consequently, the issue of sustainable waste management has become an important priority for policymakers and other stakeholders of the society. Although the respective local administrations are responsible for collection and disposal of household and industrial wastes, privatization of the entire process has been heavily promoted and pursued by the federal government of the country. A significant number of waste dealers – both formal and informal – are currently involved in the field level. Through analysing the inputs acquired from semi-structured interviews with these waste dealers operating at Kuala Langat and Sepang districts in the Selangor state, this paper attempts to identify the roles they are playing in the overall waste management cycle, the challenges they are facing, and the untapped opportunities from their operations. This paper will help the policy makers, waste management strategists, local administrators and researchers in the field to formulate sustainable policies, and identify further areas of study in the relevant field.

description: Objective: To evaluate the association of high sensitivity C-reactive protein (hsCRP) with the presence of abdominal aortic aneurysm (AAA). Methods: Medline, Cochrane, Embase, and Google Scholar databases were searched until 22 June 2016 using the keywords predictive factors, biomarkers, abdominal aortic aneurysm, prediction, high sensitivity C-reactive protein, and hsCRP. Prospective studies, retrospective studies, and cohort studies were included. Results: Twelve case–control studies were included in the meta-analysis with a total of 8345 patients (1977 in the AAA group and 6368 in the control group). The pooled results showed that AAA patients had higher hsCRP value than the control group (difference in means = 1.827, 95% CI = 0.010 to 3.645, p = .049). Subgroup analysis found AAA patients with medium or small aortic diameter (<50 mm) had higher hsCRP plasma levels than the control group (difference in means = 1.301, 95% CI = 0.821 to 1.781, p < .001). In patients with large aortic diameter (≥50 mm), no difference was observed in hsCRP levels between the AAA and control groups (difference in means = 1.769, 95% CI = −1.387 to 4.925, p = .272). Multi-regression analysis found the difference in means of hsCRP plasma levels between AAA and control groups decreased as aortic diameter increased (slope = −0.04, p < .001), suggesting that hsCRP levels may be inversely associated with increasing aneurysm size. Conclusions: Our findings suggest that hsCRP levels may possibly be used as a diagnostic biomarker for AAA patients with medium or small aortic diameter but not for AAA patients with large aortic diameter. The correlation between serum hsCRP level and AAA aneurysm is not conclusive due to the small number of included articles and between-study heterogeneity.

description: ABSTRACT The issue of sustainable waste management has become an important priority for policymakers and other relevant stakeholders of Malaysia as the country prepares to project itself as a developed nation. Despite several attempts by the government, such as enactment of new laws and pursuing privatisation, Malaysia is still lagging behind significantly in sustainable waste management practices, particularly in the area of recycling. Based on studies conducted in the Selangor state of Malaysia, this paper attempts to analyse the current waste management practices of Malaysia along with their problems and prospects, and examine the steps taken by the government and other stakeholders for attaining sustaining waste management practices. The paper will help the policy makers, waste management strategists, local administrators and researchers in the field to formulate sustainable policies and identify further areas of study in the relevant field.

The Experience of Self-Harming Behaviours That Inflict External Injuries to the Body in UK-Based Bangladeshi, Indian and Pakistani Females: An Interpretative Phenomenological Analysis
Creators: name: Aktar, Sharmin
Publisher: name: University of East London
Year: 2022

description: Previous studies carried out on self-harm have consistently reported a higher level of self-harm among South-Asian women. They have shown that these women are also least likely to seek professional support from mental health professionals. However, previous studies have clustered the large ethnic group together, regardless of the differences between them, looked at all types of self-harming behaviours as similar and predominantly carried out quantitative studies. Therefore, the present study investigated the experience of self-harming behaviour that inflicts external injuries to the body in Indian, Pakistani, and Bangladeshi females. A total of eight participants were recruited via purposive sampling and semi-structured interviews were carried out. The interviews were analysed from an Interpretative Phenomenological Analysis (IPA). Analyses were carried out on an individual and group level and four super-ordinate themes, and eleven sub-ordinate themes emerged. The superordinate themes were: ‘Powerlessness’ (‘Entrapment’, ‘Internalised Negativity’ & ‘Abused by my Environment’), ‘Mitigation’ (‘Releasing my Overwhelming Emotions’, ‘Connecting to my Pain’ & ‘Addicted to Self-harm’) and ‘Self-harm is Wrong’ (‘It must be Hidden’, ‘What have I done to myself?’ & ‘My Self-harm is Sinful’). The analyses revealed what appears to be novel insights on the impact and importance of the South-Asian cultural values and beliefs on the experience of self-harm in South-Asian women. The findings have been discussed relative to previous studies of this phenomenon. Also discussed are the strengths and limits of the study, clinical recommendations, and future research areas.

description: Abstract This study is an attempt to assess the status of current practices of internal control system among different service schemes of public sector in Malaysia. This study collected primary data based on a set of questionnaire survey among the head of department of 109 departments and agencies under 24 federal ministries including the Prime Minister Department in Malaysia. The data were collected based on the opinion about ten factors of internal control practices in the department or agency by using seven-point Likert scale. The data are analysed under descriptive statistics and factor analysis. Further, the reliability of the data is tested by using Cronbach alpha test, and the validity of data is tested by checking the normality of data through Shapiro Wilk test and graphically. Overall, 86.2% of the respondents mentioned that they practice internal control system in their department. However, the priority of these ten factors of internal control differs among the services schemes. Overall the internal control system of the financial schemes group is strong, but their emphasis on the documentation is at the average level only. However, the internal control in the engineering, information system, education and medical & health schemes are below the overall average internal control score. The public sector in Malaysia needs to focuses more on internal control and its proper assessment system to become a reliable and efficient sector.

By means of constructing a semi-definite program subject to linear matrix inequality constraints based on this data-dictionary, direct data-driven verification of $(Q,S,R)$-type of dissipativity properties of the data-generating LPV system is achieved. Multiple implementation methods are proposed to achieve efficient computational properties and to even exploit structural information on the scheduling, e.g., rate bounds. The effectiveness and trade-offs of the proposed methodologies are shown in simulation studies of academic and physically realistic examples.

description: A highly efficient and convenient method was developed to synthesize 2,7-dimethyl-3- phenyl- quinazolin-4(3H)-ones from 2-acetamidobenzoic acid, arylamines, arylhydrazines and arylacylhydrazines. Quinazolin-4(3H)-ones were obtained in good to excellent yields (85–98%) using dropwise POCl3 as a condensing agent in acetonitrile. Theoretical calculations were performed to explore the competition reaction pathways and the corresponding free energy profiles for the reaction of 2-acetamido-4-methyl-benzoic acid with aniline. The calculations show that the reaction proceeds through three different stages, including the formation of benzoxazin-4-one, diamide and quinazolin-4(3H)-one. The formation of benzoxazin-4-one follows a Vilsmeier-Haack mechanism, in which the POCl3 transfers the 2-acetamido-benzoic acid into an imidoyl chloride, followed by intramolecular attack of the carboxyl oxygen involving addition-elimination sequence. The formation of diamide is initialized by the nucleophilic attack of the aniline nitrogen atom on the carbonyl carbon of benzoxazin-4-one, accompanied by aniline-assisted proton transferring. The formation of quinazolin-4(3H)-one follows an intramolecular nucleophilic addition-elimination mechanism, where the POCl3 helps the elimination of water. The present studies provide insight into the mechanism for the formation reactions of quinazolin-4(3H)-ones in the presence of POCl3.

description: Abstract Bangladesh is one of the largest and richest floodplain lands in the world. There are 3 million hectares of medium and deep flooded areas. In the dry season these land are used for rice production, but these lands remain unutilized or underutilized for a long period because of flooding. Recently, rice and fish culture is practiced in dry and flooding season under community based fisheries management (CBFM) in Kalmina Beel, Fulbaria, Mymensingh and Angrar Beel, Pirganj, Rangpur areas as case studies. Assessment of the challenges and problems of these beels will help to implement it in other floodplain areas of Bangladesh that will help utilize land and waterbodies with a good source of food, employment and better income source for poor people. To understand the challenges of implementation of CBFM, this study was conducted on Beel Mail at Rajshahi in Bangladesh as a case study. This study conducted focus group discussion among the CBFM stakeholders. It was revealed that lack of skills, education, technological knowledge, and conflict among the stakeholders are the main internal constraints. Lack of coordination among the government agencies, improper facilities for marketing, infrastructure, and financial services, and environmental externalities were identified as major external constraints of successful implementation of CBFM. Some policy recommendations for the successful implementation of the CBFM have been formulated.

description: AbstractUnderstanding the interspecific relationships for proper management of an ideal fishery system, food, andfeeding habits of fishes are prerequisites. The food and feeding habits including types and amount of feed andseasonal pattern of feeding were studied. 168 Aspidoparia morar were collected from the River Padma,Rajshahi, Bangladesh from May to December, 2011. The relationship between total length and alimentary canallength was tested using OLS regression. Qualitative as well as quantitative analyses of stomach and gut contentsof each fish were done by percentage of occurrence and point method and fullness of stomach was measured byfullness index method. Aspidoparia morar was omnivorous due to the presence of both phytoplankton(Chlorophyceae, Euglenophyceae, Bacillariophyceae, Cyanophyceae) and zooplankton (Rotifera, Crustacea) inthe gut content. Based on the point method, the average percentage of phytoplankton and zooplankton was80.71% and 19.29%, respectively. The highest average percentage of fullness was 72.62% in October whereasthe lowest was 56.55% in December. The highest average percentage of emptiness recorded was 43.45% inDecember and the lowest was 27.38% in October. Total length was found statistically positively significant(P0.01) with the alimentary canal length. Overall, the article concludes that Aspidoparia morar is an omnivorewith a higher feeding preference for phytoplankton and the food habits change with the seasons based on thequalitative and quantitative analysis of food.

description: Abstract: This investigation quantified spatial variability of heavy metals and followed methods of the U.S. Environmental Protection Agency (EPA) to estimate the hazard indices as well as cancer risks associated with consuming fish caught in the waters of the Langat river basin area, Malaysia. The calculation of metal pollution index (MPI) was carried out to classify the study area according to the level of contamination and the order of stations from highest to lowest MPI values was Langat river > Cempaka lake > Engineering pond > Pond B > Pond A > Jugra > Bandar. The level of exposure due to the consumption of each chemical in Tilapia fish tissue was estimated in an average daily dose equation. The calculated HI ranging from 0.24 to 1.88 indicated 71% stations were in the risk level. Potential carcinogenic risks associated with the ingestion of heavy metals in Tilapia fish were evaluated probabilistically by performing 10,000 trials for Monte Carlo simulation. Cancer risk calculations exceeding the U.S. EPA’s acceptable risk level of 1 in 1,000,000 (or 10-6) included Ni (7.3×10-4) and Cd (2.1×10-6). However, the average carcinogenic risk (2.4×10-4) exceeded the accepted risk level to a great extent. The recommended daily ingestion rate of Tilapia for Malaysian people inhabiting Langat river basin area was calculated considering 95th percentile TR value of 10-6 as an acceptable risk where it is revealed that consumption of Tilapia should be reduced about 67% from the current level to have an acceptable risk of cancer

description: Abstract Heavy metals are widely used in various industries and became a great concern all over the world due to environmental contamination. This study provides an assessment of seasonal variability and risks to human health associated with the exposure to heavy metals concentrated in Langat river water of Malaysia. The Department of Environment (DOE) Malaysia kindly provided the heavy metal concentration data in water for this study. Several multivariate estimation such as an independent t test, box-and-whisker plot and Principal component analysis were carried out to evaluate the seasonal variation of metals concentration in water.The average value of ten analyzed metals was 250.81 μg/l and followed in order of abundance by August > Jun > February > October > April > December > March > May > September > January > July > November. The calculated HPI was 123.42, which is far above the critical index value of 100, indicating pollution with respect to heavy metals. Estimates of health risks associated with river water were summarized according to non-carcinogenic and carcinogenic health effects. No potential threat was detected for non-carcinogenic risk as the HI values calculated were <1. Potential carcinogenic risks associated with the ingestion and dermal absorption of heavy metals in water were evaluated probabilistically by performing 10,000 trails for Monte Carlo simulation where potential carcinogenic risk exists in case of Cd and As.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Excerpts from the report: Volume and total value of rapeseed and rapeseed oil marketed in the United States are small when compared to the total marketings of domestically produced oilseeds and vegetable oils. This is due to several factors: (1) small domestic production, (2) greater availability and lower prices for competing oils, (3) limited industrial uses, and (4) import duty and tax restrictions. Rapeseed is grown for food oil marketing in Europe and Asia but it is not processed for food in the United States. Rapeseed has three major uses as: (1) crushings of seed for oil and meal, (2) bird feeds, and (3) planting seed. Domestically-produced rapeseed contributes a minor part to the commercial market. Domestic oil mills that crush domestic and imported rapeseed supply 5 percent or less of the total rapeseed oil requirements. Factors that influence distribution and usage patterns of rapeseed oil in United States markets are: (1) rapeseed oils are limited by price-property criteria to specific end-uses; (2) manufacturers who take most of the oil require some further processing before use, such as blowing or vulcanization, and (3) production, processing, and usage of rapeseed oil involve only a few firms.
