Throttled Load Balancing Scheduling Policy Assist to Reduce Grand Total Cost and Data Center Processing Time in Cloud Environment Using Cloud Analyst

Cloud Computing is computing technology in which the word cloud is defined as delivery of demand services and resources from user's application to cloud data center through internet connection as pay on demand. Cloud computing has face lots of challenges like security, data migration, work load management, data integrity, confidentiality and many more. In cloud computing, data is t on cloud data center and cloud service provider s provides data to the customer as per their requirement. Customers also access data from anywhere any place ubiquitously. In cloud computing load balancing technology is used to distribute workload for balancing load between two or more cloud server. Load balancing main aim is to optimize resource utilization, maintain cost of data center and virtual machine, maximize throughput, reduce response time and avoid overloading of load. The main objective of this research paper is to reduce data center transfer cost, total virtual machine cost, data center processing time and reduce response time using throttled load balancing policy with optimize response time service based policy. In this research paper researcher used cloud analyst simulator of cloudsim for simulation and modeling of data. This study has evaluated throttled load balancing and their optimization criteria like data center processing time and reduces cost. One more thing studied is this experiment has done for hybrid cloud by adding user bases from private and public cloud.
A Novel Approach for Gesture Spotting in an Assamese Gesture-Based Character Recognition System using a Unique Geometrical Feature Set

Gesture Recognition (GR) systems have gained tremendous importance in recent times as these have established themselves as important elements of Human Computer Interaction (HCI). A significant attribute of GR systems is Gesture-Based Character Recognition (GBCR). GBCR systems serve as a powerful mediator for communication among people having hearing and speech impairments as well as with common people. They can also serve as a rehabilitative aid for people with motor disabilities who cannot write with pen on paper, or face difficulty in using common human-machine interactive (HMI) devices. A challenging task in GBCR system is gesture spotting, i.e. determining the start and end points of different segments in a character sequence. In this paper, we have addressed the design of an Assamese gesture-based character spotting system, which spots the different segments present in an overall character sequence. Partitioning of character segments is done by employing a unique geometrical feature set comprising of three features namely linear eccentricity, flatness and area of ellipse. The performance of our proposed system is validated by taking into account the vowels and numerals of Assamese alphabets. Moreover, the efficacy of our proposed hand segmentation module enables the system to tackle different background conditions like complex background containing multiple objects and scenes involving multiple signers in the background.
Depression Negatively Impacts Survival of Patients with Metastatic Prostate Cancer

The prevalence of depression in patients with cancer is high, especially for patients with advanced cancer. In this study, we evaluated the prevalence of depression in prostate cancer patients in Taiwan and the association between depression and mortality in prostate cancer. This study included 1101 newly diagnosed patients with prostate cancer. We tracked the medical information of these patients from diagnosis until the end of 2012. Patients were divided into two groups according to presence or absence of depression diagnosis, and were further divided into three stages by initial treatments: localized or locally advanced, metastatic, and castration-resistant prostate cancer. Of 1101 participants, 267 (24.3%) had depression. By the end of the follow-up period (M = 8.30 ± 3.12 years), 77 (28.8%) patients in the depression group and 194 (23.3%) in the non-depressed group died. Depression was associated with higher mortality risk, (aHR 1.37; 95% CI [ 1.04–1.80]; p value 0.01). Patients in the metastatic prostate cancer group with depression had a significantly higher mortality risk compared to the non-depressed group, (aHR, 1.49; 95% CI [1.05–2.11]; p value 0.02). The impact of depression on mortality risk was not significant in either the localized or locally advanced or the castration-resistant prostate cancer groups. Our study showed that depression is related to an increased mortality risk for patients with prostate cancer, especially for metastatic prostate cancer. These results indicate that urologists should pay attention to the mood and psychiatric disorders of patients with prostate cancer.
Changes in the inflammatory and oxidative stress markers during a single hemodialysis session in patients with chronic kidney disease

Abstract Background: Cardiovascular disease (CVD) is a common cause of morbidity and mortality in end-stage renal disease (ESRD) patients on hemodialysis (HD) among whom it is 5–20 times higher than in the general population. Some of the nontraditional risk factors such as oxidative stress and inflammation are related to the progress of CVD in HD patients. Several, but not all studies, reported that inflammatory and oxidative stress markers are increased during a single session of HD, mimicking changes that occur during acute immune activation. This study was taken up to evaluate the changes in the inflammatory and oxidative stress markers during a single HD session in patients with chronic kidney disease. Methods: Twenty-five ESRD patients on maintenance HD and 25 controls were included in the study. Blood samples were obtained from the patients before starting of hemodialysis (pre-HD) and after completion of hemodialysis (post-HD). The changes in serum Pentraxin-3, hs-CRP, malondialdehyde (MDA) and ferric reducing ability of plasma (FRAP) levels were measured in pre- and post-HD ESRD patients and compared with healthy control group. Results: This study found increased levels of Pentraxin-3, hs-CRP, MDA, and decreased level of FRAP in HD patients compared to controls. Conclusions: Hemodialysis procedure contributes to inflammation and oxidative stress.
Optimal Sensor Placement for Source Localization in NLOS Conditions

The problem of sensor placement for passive source localization under the non-line of sight signal propagation is considered in this paper. To this end, first we derive the Cramer-Rao lower bound for the time of arrival based source localization under non-line of sight conditions. Then, the optimal arrangement of sensors to achieve this lower bound is obtained in the two important cases with all of the receivers being non line of sight ones in the first case and a combination of line of sight and non-line of sight receivers in the 2nd case.
Emerging Functions for Cell Wall Polysaccharides Accumulated during Eudicot Seed Development

The formation of seeds is a reproductive strategy in higher plants that enables the dispersal of offspring through time and space. Eudicot seeds comprise three main components, the embryo, the endosperm and the seed coat, where the coordinated development of each is important for the correct formation of the mature seed. In addition, the seed coat protects the quiescent progeny and can provide transport mechanisms. A key underlying process in the production of seed tissues is the formation of an extracellular matrix termed the cell wall, which is well known for its essential function in cytokinesis, directional growth and morphogenesis. The cell wall is composed of a macromolecular network of polymers where the major component is polysaccharides. The attributes of polysaccharides differ with their composition and charge, which enables dynamic remodeling of the mechanical and physical properties of the matrix by adjusting their production, modification or turnover. Accordingly, the importance of specific polysaccharides or modifications is increasingly being associated with specialized functions within seed tissues, often through the spatio-temporal accumulation or remodeling of particular polymers. Here, we review the evolution and accumulation of polysaccharides during eudicot seed development, what is known of their impact on wall architecture and the diverse roles associated with these in different seed tissues.
Enhancing SKA Band 1 Polarimetry by Using Two Different Feed Rotations

We investigate the possibility of enhancing the polarimetric performance of the Square Kilometre Array (SKA) telescope's band 1 by mounting the feeds with two different rotations relative the dish. One rotation aligns the two polarizations along the horizontal and vertical directions and the other rotation is 45 degrees to the horizontal, vertical directions. Taken together, this configuration amounts to introducing a simple and cheap type of polarization diversity. We find that such a configuration can improve polarimetry. This is important since the offset gregorian dish design employed for SKA1-mid tends to produce beam-shapes that are not rotationally symmetric, and thus polarimetry tends to vary azimuthally.
Laboratory and Field Assessments of Erythritol Derivatives on the Survival, Reproductive Rate, and Control of Drosophila suzukii (Diptera: Drosophilidae)

Abstract Spotted-wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a vinegar fly introduced unintentionally into the United States. Since 2008, D. suzukii has reduced annual berry yields from 6 to 100%. Effective control of D. suzukii during harvest requires weekly applications of low-residual, broad-spectrum insecticides that are unavailable for organic farming. A novel ingestible insecticide, a 4-carbon polyol, mesoerythritol (erythritol), was found to kill 75 to 100% of larval and adult D. suzukii. However, mesoerythritol, at effective concentrations (0.5–1.0M), may be cost-prohibitive. Therefore, we conducted laboratory tests to assess the effects of lower cost derivatives of erythritol, namely the pentaerythritol series of 1,3-diols on D. suzukii pupal production, adult production, adult mortality, brood output, and reproductive increase. We then selected the two most promising compounds for a field test on fruiting rabbiteye blueberry. From 90 to 100% of adults died when fed food moistened with 1M solutions of mesoerythritol and pentaerythritol. Mesoerythritol and dipentaerythritol at a concentration of 1M were ovicidal/ larvicidal, killing ≥85% of immatures. Overall, 1M mesoerythritol killed 80% or more larvae and adults, thus bringing populations to near zero. The heaviest compound of this series, tripentaerythritol, at all concentrations, was largely benign to both adults and immatures. Thus, we cannot recommend tripentaerythritol for D. suzukii control. In a blueberry field, 0.5M mesoerythritol and 0.5M pentaerythritol, each by themselves, reduced egg infestation by 64% and larval infestation by 93%; their combination (0.25M mesoerythritol and 0.25M pentaerythritol) achieved even greater egg control with 82% fewer eggs infesting blueberry fruits.
Backward Second Harmonic Generation in Silicon Waveguide

The first report on backward second harmonic generation (SHG) in silicon waveguides is presented in this paper. Second-order nonlinearlty, $\chi^{(2)}$, in silicon is realized by using large $\chi^{(3)}$ of silicon and large DC electric field obtained in an embedded reverse-biased pin diode via four-wave mixing, an effect which is known as electric filed induced SHG. The considered pin diode has periodic structure along the waveguide to achieve quasi-phase matching technique. An efficiency up to $\pmb{P_{2\omega}/P_{\omega}=40}$ % is predicted which is 20-fold of all previously reported values, based on the best of our knowledge. Besides, the generated power of the second harmonic frequency can be controlled by applying voltage and even be more efficient with upper limit of ~53%.
EMPLOYEE TRAINING IN INTERNATIONAL LUXURY HOTEL CHAINS: EVIDENCE FROM SERBIA

Increased competition in international luxury hotel industry requires the hotels to continuously improve their HRM policies and practices, with a particular focus on employee training. Hotel industry globally employs a large number of people with high labour turnover. Training employees in hotels, especially in international luxury hotel chains, has always represented a challenge since guests demand high-quality personalized services. The aim of this paper is to examine how international luxury hotel chains in a developing country, such as Serbia, implement training programs. The research was conducted in six five-star and four-star hotels in Belgrade members of international luxury hotel chains, through in-depth interviews with managers from these hotels. The research has shown examined hotel implement some of the training programs usual for luxury hotel chains. However, in order to develop their local talent pools and improve staff skills on a continuous basis, the luxury hotels in Serbia need to re-examine their training systems, having in mind that most of them are highly standardized, to implement more diversified training plans, and provide more overseas training opportunities for local employees from Serbia.
Ligand Recognition Determines the Role of Inhibitory B Cell Co-receptors in the Regulation of B Cell Homeostasis and Autoimmunity

B cells express various inhibitory co-receptors including CD22, CD72, and Siglec-G. These receptors contain immunoreceptor tyrosine-based inhibition motifs (ITIMs) in the cytoplasmic region. Although many of the inhibitory co-receptors negatively regulate BCR signaling by activating SH2-containing protein tyrosine phosphatase 1 (SHP-1), different inhibitory co-receptors have distinct functional properties. CD22, Siglec-G, and CD72 preferentially regulate tonic signaling in conventional B cells, B-1 cell homeostasis, and development of lupus-like disease, respectively. CD72 recognizes RNA-related lupus self-antigen Sm/RNP as a ligand. This ligand recognition recruits CD72 to BCR in Sm/RNP-reactive B cells thereby suppressing production of anti-Sm/RNP autoantibody involved in the pathogenesis of lupus. In contrast, Siglec-G recognizes α2,3 as well as α2,6 sialic acids whereas CD22 recognizes α2,6 sialic acid alone. Because glycoproteins including BCR are dominantly glycosylated with α2,3 sialic acids in B-1 cells, Siglec-G but not CD22 recruits BCR as a ligand specifically in B-1 cells, and regulates B-1 cell homeostasis by suppressing BCR signaling in B-1 cells. Thus, recognition of distinct ligands determines functional properties of different inhibitory B cell co-receptors.
Ontological Representation of Constraints for Geographical Reasoning

We describe a framework that supports multiple types of constraint-based reasoning tasks on a geographic domain, by exploiting a semantic representation of the domain itself and of its constraints. Our approach is based on an abstract graph representation of a geographical area and of its relevant properties, for performing the reasoning tasks. As a test-bed, we consider the domain of Ecological Networks (ENs), which describe the structure of existing real ecosystems and help planning their expansion, conservation and improvement by introducing constraints on land use. While some previous work has been done about supporting the verification of compliance of fully specified ENs, we aim at taking a significant step further, by addressing the automatic suggestion of suitable aggregations of land patches into elements of the EN. This automated generation of EN elements is relevant to support the human planner in the design of public policies for land use because it leverages automated tools to carry out a possibly lengthy and error-prone task.

This paper presents a method to design high-quality 3D equipment for virtual laboratories. A virtual control laboratory is designed on large-scale educational purpose with merits of saving expenses for universities and can provide more opportunities for students. The proposed laboratory with more than 30 virtual instruments aims at offering students a convenient experiment as well as an extensible framework for experiments in a collaborative way. Hardware-in-the-loop (HIL) simulations with realistic 3D animations can be an efficient and safe way for verification of control algorithms. Advanced 3D technologies are adopted to achieve convincing performance. In addition, accurate mechanical movements are designed for virtual devices using real-time data from hardware-based simulations. Many virtual devices were created using this method and tested through experiments to show the efficacy. This method is also suitable for other virtual applications. The system has been applied to a creative automatic control experiment course in the Harbin Institute of Technology. The assessment and student surveys show that the system is effective in student's learning.
Enhanced Sentiment Classification Using Geo Location Tweets

Information shared by millions of people in social networks. It is an important way to know the views on political issues, the vision of social problems, the latest trends, commercial websites, etc. In particular, Twitter is an important source of knowledge. It is useful to perform a moral assessment of the service. The classification of emotions on tweets has given a financial and effective form to determine public sentiment. In this research, more than 30,000 location-based tweets are collected from the Twitter page also emotions (emoji‘s) and the abbreviated form of words are used for the sentiment classification by replacing in top form, then perform the opinion classification in 5 categories, extreme positive, positive, neutral, negative and extreme negative classes. Suppliers and shareholders help to take into account the opinions of modes, services, transactions, etc from a particular geographical location. It also performs a logical analysis of many products or services on the same tool.
Graphene/Silicon Schottky Junction Solar Cells

Several emerging application domains such as Internet of Things (IoT) and wearable electronic microsystems demand flexible solar cells that exhibit simultaneously low cost and high efficiency. Recent advances in the field of graphene-based solar cells have allowed the demonstration of cells with these features. In particular, graphene/silicon Schottky junction solar cells have demonstrated a very interesting performance in this context. The paper, after a review of the graphene-based solar cells, reports on some numerical results on a graphene-on-silicon flexible solar cell having an efficiency > 10% and two important advantages, the environmental stability and the low complexity of the fabrication process. The design of this solar cell has been carried out through a general and accurate mathematical model, which has been validated by using experimental data reported in literature.
Harvesting Organization Linked Data from the Web

: In this paper, we describe our approach of automatically extracting property-value pairs from the Web for organizations when only the name and address information are known. In order to explore the enormous knowledge from the Web, we ﬁrst retrieve the Web pages containing organization properties by search engine, and then automatically extract the property-value pairs regardless of heterogeneous Web page structures. Our method does not require any training data or human-made template. We have constructed an organization knowledge base containing 3 million entities extracted from the Web for 4.2 million organizations which only have name and address information. The experiment shows that our approach makes it possible and effective for people to construct their own knowledge base.
Chiropteran diversity in the peripheral areas of the Maduru-Oya National Park in Sri Lanka: insights for conservation and management

Abstract In Sri Lanka, there are 31 species of bats distributed from lowlands to mountains. To document bat diversity and their habitat associations, 58 roosting sites in Maduru-Oya National Park periphery were surveyed. Fifteen bat species were recorded occupying 16 different roosting sites in this area. Among all the species recorded, Rhinolophusrouxii was the most abundant species per roosting site whereas Kerivoulapicta was the least abundant. A road-kill specimen similar to genus Phoniscus was found during the survey, a genus so far only documented in Southeast Asia and Australasia. Although our study area provided habitats for a diverse chiropteran community, the colony size per roost was remarkably low. Although our study area is supposedly a part of the park’s buffer zone, many anthropogenic activities are threatening the bat community: felling large trees, slash-and-burn agriculture, excessive use of agrochemicals, vengeful killing, and subsidized predation. We strongly recommend adoption of wildlife-friendly sustainable land management practices in the buffer zone such as forest gardening, agroforestry (alley cropping, mixed-cropping), and integrated farming. Bat conservation in this region should take a landscape-scale conservation approach which includes Maduru-Oya National Park and other surrounding protected areas into a regional conservation network. Extents of undisturbed wilderness are dramatically declining in Sri Lanka; thus, future conservation efforts must be retrofitted into anthropocentric multiuse landscapes and novel ecosystems like areas surrounding Maduru-Oya National Park.
Adaptation of brain functional stream architecture in athletes with fast demands of sensorimotor integration

Training‐induced neuroplasticity has been described in athletes' population. However, it remains largely unknown how regular training and sports proficiency modifies neuronal circuits in the human brain. In this study, we used voxel‐based morphometry and stepwise functional connectivity (SFC) analyses to uncover connectivity changes in the functional stream architecture in student‐athletes at early stages of sensorimotor skill training. Thirty‐two second‐year student‐athletes whose major was little‐ball sports and thirty‐four nonathlete controls were recruited for the study. We found that athletes showed greater gray matter volume in the right sensorimotor area, the limbic lobe, and the anterior lobe of the cerebellum. Furthermore, SFC analysis demonstrated that athletes displayed significantly smaller optimal connectivity distance from those seed regions to the dorsal attention network (DAN) and larger optimal connectivity distance to the default mode network (DMN) compared to controls. The Attention Network Test showed that the reaction time of the orienting attention subnetwork was positively correlated with SFC between the seeds and the DAN, while negatively correlated with SFC between the seeds and the DMN. Our findings suggest that neuroplastic adaptations on functional connectivity streams after motor skill training may enable novel information flow from specific areas of the cortex toward distributed networks such as the DAN and the DMN. This could potentially regulate the focus of external and internal attention synchronously in athletes, and consequently accelerate the reaction time of orienting attention in athletes.
