Implementing private cloud at IIT Roorkee: an initial experience

Cloud Computing has emerged as a promising technology to provide computing resources as public utility. Its features like cost effectiveness, pay per use and scalability have attracted many organization to adopt cloud computing environment in order to cut down IT cost. Hence market is blooming with the cloud vendors like Amazon, IBM who provide Infrastructure as a service. It saves the organizations form the complications of building infrastructure and hence the organization can concentrate on the quality of services and products to be delivered. Though the features like cost effectiveness and scalability have made cloud popular, at the same time, the features like multi-tenancy has refrained some of the organizations dealing with confidential information, from adopting cloud. This is because in the changed computing paradigm, the information of the client is present in the vendor's premises. This implies less control over the data. For educational institutes, which need to secure the confidentiality and privacy of data, a private cloud can be a good solution. Hence we propose private cloud architecture for educational institute which can provide Infrastructure as a Service to the students and teachers without compromising the confidentiality of information. The proposed architecture has been deployed using open-source cloud computing tool kit called OpenNebula. It has been compared with traditional computing infrastructure. Results show that our architecture increases resource utilization up to 85%, thus increasing the efficiency.
Challenging Horizontal Movement of the Body During Sit-to-Stand: Impact on Stability in the Young and Elderly

ABSTRACT There are 3 significant challenges to sit-to-stand: (a) bringing the center of mass forward, (b) vertically raising the center of mass from the sitting to standing position, and (c) transition from a relatively large and stable base of support in sitting to a considerably smaller base of support when standing. The authors explored the challenges to stability control following sit-to-stand when the requirement for horizontal movement of the center of mass was influenced by foot position and their potential effect on the preceding phases of sit-to-stand. Eleven healthy young and 11 healthy elderly individuals performed the sit-to-stand with their feet further away and closer to the chair. Kinetic and kinematic data were recorded. Regardless of foot position, challenges in stability were greater in elderly participants than young participants despite their similar movement time and shear forces. The greater instability in elderly participants, despite their comparable movement characteristics, emphasizes the importance of stability control following sit-to-stand performance. For both young and elderly participants, the sit-to-stand duration and the shear forces were greater in the far condition. However, foot position did not affect the stability measures (i.e., duration of the stabilization phase and the total center of pressure path during the 1st second of the stabilization phase).
CAHPS and Comments

Objectives: To investigate whether content from patient narratives explains variation in patients’ primary care provider (PCP) ratings beyond information from the closed-ended questions of the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Clinician and Group Survey and whether the relative placement of closed- and open-ended survey questions affects either the content of narratives or the CAHPS composite scores. Methods: Members of a standing Internet panel (N = 332) were randomly assigned to complete a CAHPS survey that was either preceded or followed by a set of open-ended questions about how well their PCP meets their expectations and how they relate to their PCP. Results: Narrative content from healthier patients explained only an additional 2% beyond the variation in provider ratings explained by CAHPS composite measures. Among sicker patients, narrative content explained an additional 10% of the variation. The relative placement of closed- and open-ended questions had little impact on narratives or CAHPS scores. Conclusion: Incorporating a protocol for eliciting narratives into a patient experience survey results in minimal distortion of patient feedback. Narratives from sicker patients help explain variation in provider ratings.
The Wage Effects of Sexual Orientation Discrimination

This study is the first to apply the econometric tools developed in the study of race and gender discrimination to the newer question of sexual orientation discrimination. Analyzing pooled 1989–91 data from a national random sample, the General Social Survey, the author finds that gay and bisexual male workers earned from 11% to 27% less than heterosexual male workers with the same experience, education, occupation, marital status, and region of residence. There is also evidence that lesbian and bisexual women earned less than heterosexual women, but this result is not consistently statistically significant across all variable definitions and specifications.
Economic Games Quantify Diminished Sense of Guilt in Patients with Damage to the Prefrontal Cortex

Damage to the ventromedial prefrontal cortex (VMPFC) impairs concern for other people, as reflected in the dysfunctional real-life social behavior of patients with such damage, as well as their abnormal performances on tasks ranging from moral judgment to economic games. Despite these convergent data, we lack a formal model of how, and to what degree, VMPFC lesions affect an individual's social decision-making. Here we provide a quantification of these effects using a formal economic model of choice that incorporates terms for the disutility of unequal payoffs, with parameters that index behaviors normally evoked by guilt and envy. Six patients with focal VMPFC lesions participated in a battery of economic games that measured concern about payoffs to themselves and to others: dictator, ultimatum, and trust games. We analyzed each task individually, but also derived estimates of the guilt and envy parameters from aggregate behavior across all of the tasks. Compared with control subjects, the patients donated significantly less and were less trustworthy, and overall our model found a significant insensitivity to guilt. Despite these abnormalities, the patients had normal expectations about what other people would do, and they also did not simply generate behavior that was more noisy. Instead, the findings argue for a specific insensitivity to guilt, an abnormality that we suggest characterizes a key contribution made by the VMPFC to social behavior.
Unique and Joint Effects of Sexual and Racial Harassment on College Students' Well-Being

This study examined the sexual harassment (SH) and racial harassment (RH) experiences of Asian, Black, multiracial, and White male and female college students (N = 2,009). Research questions were (a) Do sex and race influence the frequency of SH and RH; (b) Do SH and RH have unique, additive, and/or interactive effects on psychological outcomes; and (c) Do sex and race moderate the relationship between SH/RH and psychological well-being? Analyses indicated that SH/RH frequency varied as a result of one's combined sex–race identity, SH/RH had individual, additive, and interactive effects on psychological well-being, and both sex and race moderate the relationships between harassment and well-being. Further, three-way interactions of sex, race, and harassment type were found for the prediction of well-being indicators.
Choices of approaches in e-moderation: Conclusions from a grounded theory study

Much has been published in recent years about the desirable nature of facilitated interactions in online discussions for educational purposes. However, little has been reported about the roles that tutors actually adopt in real-life learning contexts, how these range between ‘tutoring, ‘managing’ and ‘facilitating’, and what the distinctions between these three roles may be. In this article choices of priorities in e-moderation, which were made in three naturalistic (real-life) case studies by three higher education practitioners, are identified and discussed. These contrasting approaches were captured and analysed using grounded theory principles. The article also discusses the occasions when the facilitation was less effective than might have been desired. It finally summarizes the potential of various approaches within e-moderation — and some of the attendant risks. The finding is that principles and practices developed for face-to-face support of student-directed learning were found equally applicable in e-moderated online group work, despite several significant differences between the two types of setting.
Plant-PrAS: A Database of Physicochemical and Structural Properties and Novel Functional Regions in Plant Proteomes

Arabidopsis thaliana is an important model species for studies of plant gene functions. Research on Arabidopsis has resulted in the generation of high-quality genome sequences, annotations and related post-genomic studies. The amount of annotation, such as gene-coding regions and structures, is steadily growing in the field of plant research. In contrast to the genomics resource of animals and microorganisms, there are still some difficulties with characterization of some gene functions in plant genomics studies. The acquisition of information on protein structure can help elucidate the corresponding gene function because proteins encoded in the genome possess highly specific structures and functions. In this study, we calculated multiple physicochemical and secondary structural parameters of protein sequences, including length, hydrophobicity, the amount of secondary structure, the number of intrinsically disordered regions (IDRs) and the predicted presence of transmembrane helices and signal peptides, using a total of 208,333 protein sequences from the genomes of six representative plant species, Arabidopsis thaliana, Glycine max (soybean), Populus trichocarpa (poplar), Oryza sativa (rice), Physcomitrella patens (moss) and Cyanidioschyzon merolae (alga). Using the PASS tool and the Rosetta Stone method, we annotated the presence of novel functional regions in 1,732 protein sequences that included unannotated sequences from the Arabidopsis and rice proteomes. These results were organized into the Plant Protein Annotation Suite database (Plant-PrAS), which can be freely accessed online at http://plant-pras.riken. jp/.
Expression and function of recombinant endothelial nitric oxide synthase gene in canine basilar artery after experimental subarachnoid hemorrhage.

BACKGROUND AND PURPOSE Gene transfer with recombinant viral vectors encoding vasodilator proteins may be useful in therapy of cerebral vasospasm after subarachnoid hemorrhage (SAH). Relaxations mediated by nitric oxide are impaired in cerebral arteries affected by SAH. The present study was designed to determine the effect of SAH on the efficiency of ex vivo adenovirus-mediated gene transfer to canine basilar arteries and to examine whether expression of recombinant endothelial nitric oxide synthase (eNOS) gene may have functional effects on vasomotor reactivity of spastic arteries affected by SAH. METHODS Replication-deficient recombinant adenovirus vectors encoding bovine eNOS (AdCMVeNOS) and Escherichia coli beta-galactosidase (AdCMVbeta-Gal) genes were used for ex vivo gene transfer. Rings of basilar arteries obtained from control dogs and dogs exposed to SAH were incubated with the vectors in minimum essential medium. Twenty-four hours after gene transfer, expression and function of the recombinant genes were evaluated by (1) histochemical or immunohistochemical staining, (2) beta-galactosidase protein measurement, and (3) isometric tension recording. RESULTS Transduction with AdCMVbeta-Gal and AdCMVeNOS resulted in the expression of recombinant beta-galactosidase and eNOS proteins mostly in the vascular adventitia. The expression of beta-galactosidase protein was approximately 2-fold higher in SAH arteries than in normal arteries. Endothelium-dependent relaxations caused by bradykinin and substance P were suppressed in SAH arteries. The relaxations to bradykinin were significantly augmented in both normal and SAH arteries after AdCMVeNOS transduction but not after AdCMVbeta-Gal transduction. The relaxations to substance P were augmented by AdCMVeNOS transduction only in normal arteries. Bradykinin and substance P caused relaxations even in endothelium-denuded arteries, when the vessels were transduced with AdCMVeNOS. These endothelium-independent (adventitia-dependent) relaxations to bradykinin observed after AdCMVeNOS transduction were similar between normal and SAH arteries, whereas those to substance P were significantly reduced in SAH arteries compared with normal arteries. CONCLUSIONS These results suggest that expression of recombinant proteins after adenovirus-mediated gene transfer may be enhanced in cerebral arteries affected by SAH and that successful eNOS gene transfer to spastic arteries can at least partly restore the impaired nitric oxide-mediated relaxations through local (adventitial) production of nitric oxide.
Error correction for multi-level NAND flash memory using Reed-Solomon codes

Prior research efforts have been focusing on using BCH codes for error correction in multi-level cell (MLC) NAND flash memory. However, BCH codes often require highly parallel implementations to meet the throughput requirement. As a result, large area is needed. In this paper, we propose to use Reed-Solomon (RS) codes for error correction in MLC flash memory. A (828, 820) RS code has almost the same rate and length in terms of bits as a BCH (8248, 8192) code. Moreover, it has at least the same error-correcting performance in flash memory applications. Nevertheless, with 70% of the area, the RS decoder can achieve a throughput that is 121% higher than the BCH decoder. A novel bit mapping scheme using gray code is also proposed in this paper. Compared to direct bit mapping, our proposed scheme can achieve 0.02 dB and 0.2 dB additional gains by using RS and BCH codes, respectively, without any overhead.
The research on security and stability of PWM technology of high-voltage high-power three-level NPC inverter

The security and stability operation mechanism is the key problem of the high power and voltage three-level neutral point clamp inverter[1]. As the security and stability of PWM is very important for normal operation of system, the control strategy and algorithm are the basis for the safety operation of the inverter. In the process of starting up the inverter, the optimal settings of minimum pulse width and secure access are the most important problems needed to be solved. In the normal operation process of the inverter, the accuracy algorithm of PWM output region identification and the dead zone insert need to be fully considered. The treatment method during the emergency stop time of the inverter is also one of the key contents of improving security and stability. And the theoretical innovation through the multi-disciplinary overlapping (such as power electronics, intelligent technology) should be adopted. Combined with existing achievements, this paper carries out research in the aspects of improving security and stability of PWM of high-voltage and high-power three-level NPC inverter. The results lay a theoretical and experimental foundation for the following theoretical research.
Peer assistance in children's problem solving

The current study aimed to investigate the extent to which the creation of a context which facilitates conversation and communication would enhance the cognitive capacities of children working on recognized problems. Using a collaborative problem-solving paradigm, the communication patterns of pairs of 4- and 7-year-old children were analysed. It was found that collaborative problem solving facilitated lower ability children's subsequent individual problem solving when they were paired with higher ability children. In addition, it was found that older children used more language during collaboration. Holding number of utterances as a covariate, older children used more procedural language and more descriptive language than younger children and lower ability children used more language for checking with their partner. These uses of language were interpreted as demonstrating awareness on the part of older children of the other person in the collaboration although the extent to which this assisted subsequent problem-solving ability in less able children of either age is not clear and requires further theoretical explication.
Solar change and climate: an update in the light of the current exceptional solar minimum

Solar outputs during the current solar minimum are setting record low values for the space age. Evidence is here reviewed that this is part of a decline in solar activity from a grand solar maximum and that the Sun has returned to a state that last prevailed in 1924. Recent research into what this means, and does not mean, for climate change is reviewed.
A Practical Design and Implementation of a Low Cost Platform for Remote Monitoring of Lower Limb Health of Amputees in the Developing World

In many areas of the world accessing professional physicians “when needed/as needed” might not be always possible for a variety of reasons. Therefore, in such cases, a targeted e-Health solution to safeguard patient long-term health could be a meaningful approach. Today's modern healthcare technologies, often built around electronic and computer-based equipment, require an access to a reliable electricity supply. Many healthcare technologies and products also presume access to the high speed internet is available, making them unsuitable for use in areas where there is no fixed-line internet connectivity, access is slow, unreliable, and expensive, yet where the most benefit to patients may be gained. In this paper, a full mobile sensor platform is presented, based around readily-purchased consumer components, to facilitate a low cost and efficient means of monitoring the health of patients with prosthetic lower limbs. This platform is designed such that it can also be operated in a standalone mode, i.e., in the absence of internet connectivity, thereby making it suitable to the developing world. Also, to counter the challenge of power supply issues in e-Health monitoring, a self-contained rechargeable solution to the platform is proposed and demonstrated. The platform works with an Android mobile device, in order to allow for the capture of data from a wireless sensor unit, and to give the clinician access to results from the sensors. The results from the analysis, carried out within the platform's Raspberry Pi Zero, are demonstrated to be of use for remote monitoring. This is specifically targeted for monitoring the tissue health of lower limb amputees. The monitoring of residual limb temperature and gait can be a useful indicator of tissue viability in lower limb amputees especially those suffering from diabetes. We describe a route wherein non-invasive monitoring of tissue health is achievable using the Gaussian process technique. This knowledge will be useful in establishing biomarkers related to a possible deterioration in a patient's health or for assessing the impact of clinical interventions.
Novel KCNQ 1 mutations in patients after myocardial infarction

Background: Patients after myocardial infarction (MI) are at greater risk of sudden cardiac death (SCD) than people in the overall population. The aim of this study was to detect mutations, including intronic ones, in the KCNQ1 gene coding for proteins of cardiac potassium channels and evaluate their possible effects on the clinical course in patients after MI. Methods: The study group was composed of 100 Polish patients after MI, which included 27 women (mean age 69 years) and 73 men (mean age 67 years). All patients underwent clinical examinations and genetic tests. The genetic test results have been correlated with the clinical data. The following parameters have been chosen as endpoints for this survey: sudden cardiac arrest (SCA) or SCD, complex ventricular arrhythmia, QT interval and QT dispersion values assessed during 24-hour Holter ECG monitoring in relation to ventricular arrhythmias as well as the minimum and maximum heart rate (HR) observed during the examination. Results: Six new mutations in the KCNQ1 gene: C2505734T, A2753831C in exons and C2505846A, G2753881A, T2755854C, T2755875G in introns. Detected intronic mutations in patients after MI were related to a worse clinical course and frequent occurrence of SCA. Conclusions: The novel intronic mutations may have a significant influence on the clinical course of the disease. (Cardiol J 2008; 15: 252–260)
Group Affect

We review and synthesize the research literature examining group affect and its consequences, focusing on groups who interact together to accomplish a task. We use a definition of group affect that incorporates the mutual influence of a group’s affective context and affective composition (the amalgamation of group members’ state and trait affect). Our focus is on the influence of group affect on individual members’ behaviors and attitudes and on group-level outcomes. We call for more research in this area, including the study of more specific discrete group emotions and a broadening of the types of groups studied in this research area.
Developing Ideal Intermediate Personality Items for the Ideal Point Model

The importance of intermediate items has been overlooked since the emergence of dominance-based Likert-type scales. The current study aims to advance our understanding of the psychometric properties of intermediate items by showing that they can be successfully calibrated by an ideal point model. A student sample and an MTurk sample were selected to answer personality scales with intermediate items included. Results showed that personality scales with intermediate items demonstrated satisfactory model fits to the ideal point model, but not to the dominance model. When analyzed with the ideal point model, intermediate items provided more information than extreme items for respondents with high latent trait levels. Among four proposed domains of intermediate items (Frequency, Average, Condition, and Transition, “FACT”), the Average domain was consistently found to exhibit the best properties. The proportion of intermediate items in the scale also affected the model fit and the validity of the scale.
Allelopathy in Spatially Distributed Populations

In a homogeneously mixing population of E. coli, colicin-producing and colicin-sensitive strategies both may be evolutionarily stable for certain parameter ranges, with the outcome of competition determined by initial conditions. In contrast, in a spatially-structured population, there is a unique ESS for any given set of parameters; the outcome is determined by how effective allelopathy is in relation to its costs. Furthermore, in a spatially-structured environment, a dynamic equilibrium may be sustained among a colicin-sensitive type, a high colicin-producing type, and a ‘‘cheater’’ that expends less on colicin production but is resistant. 7 1997 Academic Press Limited
Impact of Co-Opetition on Firm Competitive Behavior: An Empirical Examination

The authors examine how co-opetition—simultaneous cooperation and competition—affects firms'competitive behavior, proposing that differential structural positions among firms in a coopetitive network reflect resource asymmetries among them and that such asymmetries lead to differences in the volume and diversity of competitive actions undertaken by those firms. Data on cooperative network structure and competitive actions from the steel industry suggest that the firm's centrality is positively related to its volume of competitive actions and that its structural autonomy is positively related to the diversity of such actions. Moreover, market diversity moderates the impact of centrality and structural autonomy on competitive behavior.
