Commentary on Atomistic Simulations of Materials Strength and Deformation: Prospects for Mechanistic Insights

Multiscale materials modeling has emerged as a significant concept in computational materials research. We examine several case studies which seek to provide understanding of mechanical behavior of solids at the atomistic level, in the context of upper and lower limits to strength and deformation, the interplay between melting and stability criteria, the competition between pressure-induced polymorphism and amorphization, the role of kink mechanism in dislocation mobility, and the concept of a local free energy as an invariant measure of defect driving force. Through these illustrations we express the optimistic belief that further pursuits of this kind would be worthwhile.
Analysis and Prediction of University Websites Perceptions by Different User Groups

Users' subjective impressions of websites are actively being researched, as they are formed very early in the interaction and affect the whole subsequent user experience. The subjective visual complexity is known to affect both website users' cognitive load and overall affective impressions. In our work we construct artificial neural network model to predict users' perceptions of selected universities' websites without the actual users. To train the network, we joined the two kinds of data that we specially collected. The visual complexity-related metrics of websites were extracted from web interface screenshots by our dedicated visual analyzer software implementing the “human-computer vision” approach. The assessments of the homepages orderliness and overall complexity were collected from 61 human annotators of different ages and cultural/national groups. We were able to achieve moderate subjective perceptions prediction accuracy, with relative error of 73.0%. The analysis of the factors' importance suggests that the proposed index of visual-spatial complexity had considerably higher importance than the baseline frequency-based entropy measure for images. The results of our work can aid in controlling the visual complexity perception in website visitors, ultimately contributing to better web usability.

Parsing Free-Form Language Learner Data: Current State and Error Analysis

Parsing learner data with high accuracy is important for all systems that want to analyze language learner input, such as computer-assisted language learning software. State-of-the-art parsers are typically trained on news text and not on language learner data since this kind of data is often not available in sufficient quantities. Our contribution is three-fold: We provide gold-standard syntactic annotations for sentences from language learners of German, evaluate the performance of state-of-the-art parser pipelines on this corpus and explore whether augmentation of a parser with weighted constraints to avoid common structural errors could lead to improvements.
A Keyword-Based Retrieval of Data on DHT Networks using Term-Document Matrix

These days numerous distributed framework bolsters the membership capacity than catchphrase seek capacity. Case in point, Vuze licenses customers to make membership diverts in perspective of the watchword seek. Given the membership, tedious or related substance will be passed on to the client at whatever point new scenes are available. Shockingly these applications endure sick impacts of downsides, for instance, for occasion, high framework action in the center points keeping up surely understood word. In this MTAF structure to vanquish the framework action in the centers keeping up conspicuous terms. The main element of MTAF to protectively pick a subset of terms with no acknowledging negatives and to forward the substance thing toward the home focuses of such picked terms for low substance sending cost. Exploratory output considering guaranteed show that the strategies are fruitful showed up diversely in connection to existing systems. In particular, the comparability on duplication of channels is seemed to mitigate the effect of issue territories develop in view of the way that some report words are significantly more standard .
Learner’s English Proficiency and their Pragmatic Competence of Refusal Speech Acts

Abstract The present study is an attempt to investigate the relationship between language proficiency and ‎pragmatic comprehension of the refusal speech act among Iranian EFL learners. To this end, the ‎Oxford Placement Test (OPT), as a proficiency test, was given to participants and they were ‎divided into high and low level groups based on their proficiency scores. Then, a multiple-choice ‎discourse completion task (MDCT) was given to both groups to elicit their pragmatic ‎knowledge. The findings indicated that there was no significant ‎difference between high and low groups in pragmatic comprehension. In other words, language ‎proficiency was not the determining factor in the degree of pragmatic comprehension. Moreover, the results indicated that there was no correlation between learners’ language proficiency and pragmatic knowledge. Therefore, ‎in order to have pragmatically competent EFL learners, they should be taught pragmatic functions and language norms of the target language in the language classrooms. Keywords: Pragmatic comprehension, Speech acts, Refusal speech act, MDCT.
Effect of Stocking Density Stress on the Hematological Profile of Oncorhynchus mykiss

The present research aimed at the investigation into the effect of stocking density on the hematological response of Oncorhynchus mykiss maintained in flow through condition. The stock having a weight of 520.22 ± 48.20 g and 580.25 ± 52.2 g were stocked in flow through FRP tanks at the stocking density of 38 kg/m 3 and 30 kg/m 3 respectively. In order to collect blood sample for analysis, the blood was collected through cardiac puncture. Red blood cell counts (RBCc), hematocrit values (Hct), hemoglobin concentration (Hb), were analyzed through haemoanalyser, while as mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were calculated through standard formulas. Differences in hematological parameters were statistically analyzed by Student’s T-Test. The stocking density stress was evident from the significant increase ( p 0.05) in MCH and MCHC.
The e-government implementation directions in Oman: A preliminay investigation

Electronic government has established itself as the primary enabler for transforming the way government services are offered to citizens. In the gulf countries, public sector transformation efforts are focused towards increasing accessibility, availability, competitive advances and enhancing services in civil administration. The Sultanate of Oman is one such example of the Gulf countries where large investments have been made since 2003 to implement electronic services in the public sector. Using a qualitative research approach, this research investigates the improvements that have been made to facilitate these electronic services in three public organisations, and their resulting impact within the organisations. The empirical results reveal that among others, top management support, integration and IT staff skills and capabilities are the most important factors that facilitate egovernment initiatives in the Omani public sector.
Ransomware detection by mining API call usage

In the recent past one of the harmful forms of malware seen is the Ransomware. The year 2016 has seen a huge rise in ransomware attacks. According to the study by Tripwire, Ransomware has done the most amount of damage to organizations in 2017, followed by DDoS, Malicious Insiders, Phishing, and Known/Unknown Vulnerabilities. In this work, Application Programming Interface (API) calls are extracted from the executables and the most discriminating API calls are used to train a classifier to detect unknown ransomware. We have tested our method on various classifiers like Decision trees, KNN, Random forest. Class imbalance due to the difference in the number of samples available in two classes - Ransomware and benign is also considered. It is seen that Random forest with smote for class imbalance has given a detection rate of over 98%. A large number of ransomware samples have been analyzed and the discriminating API calls have been identified.
Evidence-Based Systematic Review Clinical Outcome and Return to Competition after Microfracture in the Athlete ’ s Knee : An

Microfracture is frequently used for articular cartilage repair in athletes. This study aimed to define the strength and weaknesses of this minimally invasive cartilage repair technique in the athletic population in an effort to optimize indications, functional outcome, and athletic participation after microfracture in the athlete’s knee. A systematic analysis of original studies using microfracture in athletes was performed. Functional outcome was assessed by activity outcome scores, ability to return to sports participation, timing of the return to sport, level of postoperative sports activity, and continuation of athletic competition over time. Thirteen studies describing 821 athletes were included in the analysis with an average follow-up of 42 months. Good or excellent results were reported in 67% of athletes with normal International Knee Documentation Committee (IKDC) scores in 80% and significant increase of Lysholm scores, Tegner activity scores, and Knee injury and Osteoarthritis Outcome Score (KOOS) sports subscales. Return to sports was achieved in 66% at an average of 8 months after surgery, with return to competition at the preinjury level in 67%. Forty-nine percent of athletes continued to compete without change in level of play, while decreasing function was observed in 42% after 2 to 5 years. Athlete’s age, preoperative duration of symptoms, level of play, lesion size, and repair tissue morphology affected sports activity after microfracture. Microfracture improves knee function and frequently allows for return to sports at the preinjury level, but deterioration of athletic function occurs in some patients. Several independent factors were identified that can help to optimize the return to athletic competition after microfracture in the athlete’s knee.
Expression of CXCL 12 receptors in B cells from Mexican Mestizos patients with systemic lupus erythematosus

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by B-cell hyperreactivity and the production of pathogenic anti-nuclear-directed auto-antibodies (Abs). B-cell ontogeny is partly dependent on the CXCL12/CXCR4 axis for which the contribution to SLE pathogenesis remains unclear. CXCR7, the novel receptor for CXCL12, is differentially expressed among memory B-cell subsets. However, its biological role in SLE remains to be explored. Methods: Relative CXCR4 and CXCR7 expression levels were compared by quantitative PCR in leukocytes from blood samples of 41 Mexican Mestizos patients with SLE and 45 ethnicity-matched healthy subjects. Intracellular and membrane expression of both receptors was analyzed by flow cytometry in naive and Ab-secreting B cells. B-cell responsiveness to CXCL12 was investigated using Transwell-based chemotaxis assays. Data were analyzed using the Kruskal-Wallis test for comparisons of values amongst healthy controls and patients with inactive or active SLE, and non-parametrically using the Mann–Whitney U-test for multiple comparisons and unpaired samples. Correlations were determined by Spearman’s ranking. Result: SLE leukocytes displayed reduced levels of CXCR4 and CXCR7 transcripts. In SLE patients, a significant defect in CXCR4 expression was detected at the surface of naive and Ab-secreting B cells, associated with an abnormal intracellular localization of the receptor. CXCR7 predominantly localized in cytosolic compartments of B cells from healthy and SLE individuals. Disease activity did not impact on these expression patterns. Altered receptor compartmentalization correlated with an impaired CXCL12-promoted migration of SLE B cells. Conclusions: Our data highlight a down-regulation of CXCL12 receptors on circulating B cells from SLE patients that likely influences their migratory behavior and distribution.
Protection of Smartphone, Personal Computer and Other Similar Devices from Virus Infections

The smartphones are particularly vulnerable to viruses due to their versatile communication capabilities and intermittent network connectivity. As a result, the viruses can easily spread out and cripple both the smartphone users and the cellular and telephony infrastructures. Once malware enter to the system they start to find the vulnerabilities within the operating system then perform unintended operation in the system. Most of the malwares basically attack on performance of the system, data integrity and privacy. They also play the major role in denial of service attack. These malware are also capable to infect other executable files and data. Malwares depending on their behaviour collect the information about host and harm the host computer without consent of the owner. Generally a computer virus causes damage to the host machine. The damage can be done to a number of different components of the computers operating and file system. These include system sectors, files, macros, companion files and source code. The always connected world of internet is a soft target for viruses. Viruses use internet connectivity to spread across the world faster and create havoc. Smartphones have recently become increasingly popular because they provide all in one convenience by integrating traditional mobile phones with handheld computing devices. However, the exibility of running third party softwares also leaves the smartphones open to malicious viruses. In fact, more than hundreds of smartphone viruses have emerged in the past few years, which can quickly spread through various means such as SMS/MMS, Bluetooth and traditional IP based applications. Therefore, protection of smartphone, user computer or an organization computer network from viruses is very important task.
Agricultural intensification and ecological threats around small reservoirs

Scope: questions/ challenges the tool addresses "Well-designed small reservoirs have the potential to improve the lives of people who grow irrigated crops and fish, water livestock, and use water in their households" (SIWI 2006). This positive statement needs to be revised, however, when farming practices near reservoirs generate deleterious by-products that downgrade water quality in aquatic ecosystems, and reduce the level of goods and services that reservoirs are intended to produce.
Stability of International Fisheries Agreements Using Precautionary Bioeconomic Harvesting Strategies

International agreements are necessary for exclusion of non-cooperative behavior. We parameterized an age-structured model for the North Sea herring fishery. The reference points of the current harvest control rule operationalize the precautionary approach. Applying the precautionary approach by the grand coalition adds the net present value of the fishery compared to another management approach, a fixed fishing mortality rate strategy. The fishing strategy and costs have a strong impact on the stability of the coalitions. Adopting a precautionary harvest control rule has potential to stabilize multilateral fishing agreements provided that fishing costs are not identical among countries. If they are identical, there will always be incentive for free riding.
Status of Agricultural Soil Contamination by Heavy Metals in Uasin Gishu County

Heavy metals occur naturally in the environment but anthropogenic activities such as use of chemicals and inorganic fertilizers in farms has resulted in higher concentrations of these metals relative to their normal background values leading to environmental pollution. Soil plays a central role in food safety as it determines the possible composition of food and feed at the root of the food chain. Soil pollution by heavy metals has been on the increase with its main sources being application of agricultural chemicals, improper disposal of industrial wastes, among others. This study investigated different concentrations of the heavy metals in soils of farms during the two major crop seasons in Uasin Gishu County, Kenya. The presences of heavy metals (Lead, Copper, Cadmium, Cobalt and Zinc) were determined in the three agro-ecological zones in Uasin Gishu County. These agro-ecological zones include Lower highland (LH3), Upper midland (UH4) and Upper midland (UH2). Soil samples from randomly selected farmers in the study area at the depth of 0-10cm and 10-20 cm were obtained. A total of seventy two soil samples were collected and analyzed for presence of heavy metals using ICPE-900Shimadzu inductive coupled plasma. The results obtained indicated that concentrations of the heavy metals found in soils at the three agro-ecological zones during the dry and wet seasons varied significantly.The results obtained showed that the mean concentration of Pb, Cd, Co, Zn and Cu in UH2 ranged between 12.0 –15.5ppm, 2.8–4.7 ppm, 2.5–9.5 ppm, 2.3–4.0 ppm, 8.0–16.3 ppm respectively, while in LH3 the concentration range between 10.0 –18.6 ppm, 1.8–4.8 ppm, 2.3–10.0 ppm, 2.0–17.3 ppm, 7.9–17.3 ppm respectively and finally in UH4, the mean concentrations of the five metals ranged between 10.3 –13.0ppm, 1.7–4.3 ppm, 4.0–8.5 ppm, 2.0–2.5 ppm, 7.7–16.5 ppm respectively. The level of Cd concentrations was found to exceed the WHO standard of 3mg/l in the study area. All the heavy metals concentrations varied significantly (P< 0.05) during wet and dry season indicating their mobility in the soils. The presence of heavy metals above the natural levels in the study area is attributed to sources such intensive agricultural activities. The results of this study revealed that the three agricultural zones of LH3 (Lower highland), UH4 (Upper midland) and UH2 (Upper midland) contained variable levels of heavy metals (Pb, Cd Zn, Co and Cu). The levels of heavy metals were high and may be indicative of the level of pollution resulting from farm activities in the three locations. The high level of Cadmium could be attributed to the level of use of inorganic fertilizers in the farmers fields in the study area. Keywords : Heavy metal; Agro-ecological zones; Agricultural soil; Soil depth; Uasin Gishu County.
Discussion about the Application of MOOC in Engineering Education

As a popular teaching method, the advantages and disadvantages of Massive Open Online Courses (MOOC) are analyzed in this paper. It is dedicated that MOOC could bring the reformation to higher education instead of taking the place of universities. The knowledge hierarchy and structure characteristics of the engineering courses are analyzed, therefore the possibility of applying MOOC in engineering education is deduced based on the prior experience of MOOC. A new thought of engineering education is provided by proposing a feasible plan for the implementation of MOOC in the engineering courses.
Desecularisation in Postcommunist Romania

Th e paper gives an analysis of the process as a result of which postcommunist Romania has moved from being an offi cially atheist country to being one of the most religious countries in Europe. Th e process of desecularisation is analysed in three dimensions. On the macro-level, I outline the religious headway in the most important institutions of the Romanian society, on the meso-level I analyse the changes in the organizational structure of churches and in the denominational structure of the country, while on the individual level the changes occurring in individual religiosity. In the fi nal part of the study I argue that within these dimensions desecularisation was realized to diff erent extents, while “desecularisation from above” is not likely to achieve its goals in the long run.
Gauging students’ perception on biotechnology and cloning: Empirical evidences from India and Tanzania

For over the last two decades biotechnology and its techniques in various fields have attracted much media attention. All over the globe, syllabi have been directed to teach biotechnology and biotechnological techniques to undergraduate and post graduate students in almost all public funded and private universities. Biotechnology is beset with many ethical and social controversies. Earlier, there was much hue and cry at the introduction of ‘Genetically Modified foods’ and ‘Bt Cotton’ and even a muchhyped project like the ‘Human Genome Project’ did not achieve its pace because of ethical concerns. Social scientists started conducting opinion research on such ‘modern technologies’ before giving concrete shape to their adoption. In more recent years the issue of public perception, attitude and understanding towards science, in general, and towards specific technologies like genetic engineering, cloning, genetically modified foods, biotechnology and even nuclear technology, is increasing at a fast pace all over the world. One such study has been carried out registering the perceptions of undergraduate students who are studying biology subject in India and Tanzania, on biotechnology and cloning. The survey was conducted through a questionnaire (partially structured). This analysis revealed that students favoured production of genetically modified foods but they responded that ‘biotechnological experiments’ should be conducted on plants rather than animals. Furthermore, the students were strongly supportive of medical applications of biotechnology to avoid genetic diseases. Students from the two countries gave similar responses on some issues but differed on other issues. It is worth mentioning here that, though these perception survey studies are indicative yet these are quite important in framing policies related to the introduction of new technologies and framing strategies for communication/ popularisation of these issues among the general public.
