Tetrisched : Space-Time Scheduling for Heterogeneous Datacenters

Tetrisched is a new scheduler that explicitly considers both job-specific preferences and estimated job runtimes in its allocation of resources. Combined, this information allows tetrisched to provide higher overall value to complex application mixes consolidated on heterogeneous collections of machines. Job-specific preferences, provided by tenants in the form of composable utility functions, allow tetrisched to understand which resources are preferred, and by how much, over other acceptable options. Estimated job runtimes allow tetrisched to plan ahead in deciding whether to wait for a busy preferred resource to become free or to assign a less preferred resource. Tetrisched translates this information, which can be provided automatically by middleware (our wizard) that understands the right SLOs, runtime estimates, and budgets, into a MILP problem that it solves to maximize overall utility. Experiments with a variety of job type mixes, workload intensities, degrees of burstiness, preference strengths, and input inaccuracies show that tetrisched consistently provides significantly better schedules than alternative approaches.

Performance Analysis of New Conversion Tool from Relational Datasets to XML Datasets on Selected Websites

Abstract: Over the years internet has become essential part of extensive business applications to exchange or restructure large amounts of business information. Relational database (RDB) is normally used for traditional data processing, where as Extensible Markup Language documents (XML Documents) are widely useful for performing online conversation in B2B applications. In fact XML data formats may be treated as de facto standard of data representation and exchange format for massive amount of enterprise information over the web. Performance of the application depends on both type of the data structures used and the type of the information maintained in the structures. Resource Description Framework (RDF) of semantic web uses XML to describe an Internet resource as a directed graph to provide a mechanism for describing the machine understandable meaning of any document. In this paper performance analysis is conducted for XML conversion tools developed by the authors with some of the existing tools on some selected datasets. In this analysis JDBC is used to extract data from relational datasets and Java XML Parsers to parse and extract the XML datasets. Experiments show that, the tools developed by the authors produce XML documents efficiently with high scalability than the existing tools.
Poisson-Based Continuous Surface Generation for Goal-Based Caustics

We present a technique for computing the shape of a transparent object that can generate user-defined caustic patterns. The surface of the object generated using our method is smooth. Thanks to this property, the resulting caustic pattern is smooth, natural, and highly detailed compared to the results btained using previous methods. Our method consists of two processes. First, we use a differential geometry approach to compute a smooth mapping between the distributions of the incident light and the light reaching the screen. Second, we utilize this mapping to compute the surface of the object. We solve Poisson's equation to compute both the mapping and the surface of the object.
Evaluation of a quality-of-life tool for dogs with diabetes mellitus.

BACKGROUND Diabetes mellitus (DM) management primarily focuses on improvement in blood glucose concentrations and clinical signs. A tool to assess the psychological and social impact of DM and its treatment on quality of life (QoL) previously has only been validated for feline DM. HYPOTHESIS/OBJECTIVES To validate a diabetic pet and owner-centered individualized measure of impact of DM (DIAQoL-pet) for diabetic dogs and their owners. ANIMALS/SUBJECTS: A total of 101 owners of insulin-treated diabetic dogs were recruited to complete the DIAQoL-pet. METHODS Discussions and pilot surveys with clinicians and owners of diabetic pets led to the design of 29 specific DM-associated QoL questions. Each item was scored according to impact frequency and perceived importance. An Item-Weighted-Impact-Score (IWIS) for each item was calculated, as was an Average-Weighted-Impact-Score (AWIS) by averaging all IWISs. Principal component analysis and Cronbach's α calculation assessed the measure's reliability. RESULTS The DIAQoL-pet showed high reliability (Communalities ≥0.5; Cronbach's α 0.85). The AWIS was -2.74 ± 1.7 (mean ± SD). Areas reported as most negatively impacting QoL included: "worry" (IWIS ± SD: -5.92 ± 4.3), "difficulties leaving dog with friends or family" (-5.68 ± 5.1), "worry vision" (-5.58 ± 4.6), "boarding difficulties" (-5.18 ± 5.2), "worry hypoglycemia" (-4.95 ± 4.3), "social life" (-4.82 ± 4.4), "costs" (-4.11 ± 4.7), and "future care"(-4.07 ± 4.6). Eighty-four percent of owners reported negative impact of DM on QoL. CONCLUSIONS AND CLINICAL IMPORTANCE The DIAQoL-pet proved robust when used by owners of insulin-treated diabetic dogs and identified specific areas most negatively impacting dogs' and their owners' QoL. This tool could be used as an additional assessment parameter in clinical and research settings.
Oscillations of cerebrovascular resistance throughout the menstrual cycle in healthy women

Increased concentration of endogenous estrogen during a typical menstrual cycle has been shown to correlate with augmentation of blood flow through the internal carotid arteries (ICAs), which may be related to changes in vascular resistance within the brain. In this study we investigated the effects of endogenous estrogen and progesterone on cerebrovascular impedance in young healthy women.

First order noise shaping in all digital PLLs

In this paper we introduce the architectures of TDC- and accumulator-based ADPLLs. Then, we briefly describe the block and timing diagrams of Gated-Ring-Oscillator-based and Local Oscillator-based TDCs. We present the governing equations of both TDCs and we calculate the resolution of the “first order noise shaping TDC plus moving average filter” system. We show briefly the effect of the phase error on the output of the “LO TDC plus moving average filter” system and we propose an extended LO TDC that can measure the phase error. We derive equations to predict the resolution of the extended LO TDC and we confirm the predictions with Matlab simulations. Finally, we compare in simulation the power spectral densities of the phase errors of a Gated-Ring-Oscillator-based ADPLL and of an accumulator based ADPLL with the extended LO TDC.
Excising stem samples underwater at native tension does not induce xylem cavitation.

Xylem resistance to water stress-induced cavitation is an important trait that is associated with drought tolerance of plants. The level of xylem cavitation experienced by a plant is often assessed as the percentage loss in conductivity (PLC) at different water potentials. Such measurements are constructed with samples that are excised underwater at native tensions. However, a recent study concluded that cutting conduits under significant tension induced cavitation, even when samples were held underwater during cutting. This resulted in artificially increased PLC because of what we have termed a 'tension-cutting artefact'. We tested the hypothesized tension-cutting artefact on five species by measuring PLC at native tension compared with after xylem tensions had been relaxed. Our results did not support the tension-cutting artefact hypothesis, as no differences were observed between native and relaxed samples in four of five species. In a fifth species (Laurus nobilis), differences between native and relaxed samples appear to be due to vessel refilling rather than a tension-cutting effect. We avoided the tension-cutting artefact by cutting samples to slightly longer than their measurement length and subsequent trimming of at least 0.5 cm of sample ends prior to measurement.
A threshold secure data sharing scheme for federated clouds

Cloud computing allows users to view computing in a new direction, as it uses the existing technologies to provide better IT services at low-cost. To offer high QOS to customers according SLA, cloud services broker or cloud service provider uses individual cloud providers that work collaboratively to form a federation of clouds. It is required in applications like Real-time online interactive applications, weather research and forecasting etc., in which the data and applications are complex and distributed. In these applications secret data should be shared, so secure data sharing mechanism is required in Federated clouds to reduce the risk of data intrusion, the loss of service availability and to ensure data integrity. So In this paper we have proposed zero knowledge data sharing scheme where Trusted Cloud Authority (TCA) will control federated clouds for data sharing where the secret to be exchanged for computation is encrypted and retrieved by individual cloud at the end. Our scheme is based on the difficulty of solving the Discrete Logarithm problem (DLOG) in a finite abelian group of large prime order which is NP-Hard. So our proposed scheme provides data integrity in transit, data availability when one of host providers are not available during the computation.
Cross Site Request Forgery on Android WebView

Android has always been about connectivity and providing great browsing experience. Web-based content can be embedded into the Android application using WebView. It is a User Interface component that displays webpages. It can either display a remote webpage or can also load static HTML data. This encompasses the functionality of a browser that can be integrated to application. WebView provides a number of APIs which enables the applications to interact with the web content inside WebView. In the current paper Cross site request forgery or XSRF attack specific to android WebView is investigated. In XSRF attack the trusts of a web application in its authenticated users is exploited by letting the attacker make arbitrary HTTP requests on behalf of a victim user. When the user is logged into the trusted site through the WebView the site authenticates the WebView and not application. The application can launch attacks on the behalf of user with the APIs of Webview exploiting user credentials resulting in Cross site request forgery. Attacks can also be launched by setting cookies as HTTP headers and making malicious HTTP Request on behalf of victim.

The stack is developed to meet the reliability, latency and accuracy requirements of real-time applications such as wireless automation and wireless structural health monitoring and to provide a flexible development environment for such applications. It includes MAC, routing and time-synchronization protocols as well as a node-joining algorithm. The stack is further supplemented with PC tools for optimizing the network as per the target application for easy prototyping. The design and operational aspects of the stack are verified under various deployment scenarios where the long term system and communication reliability are also tested.
Convergent validity of two motor skill tests used to assess school-age children

Abstract Background: Motor skills allow children to interact with their surrounding environment, making the progression of competent motor skills crucial to development. The most common form of motor skill assessment is through the use of performance-based tests. Performance measures need to be both reliable and valid to ensure they are of high quality. Two examples of performance-based motor skill tests often used to assess children are the Bruininks-Oseretsky Test of Motor Proficiency – 2nd edition (BOT-2) and the Movement Assessment Battery for Children – 2nd edition (MABC-2). Aim: This study investigated the convergent validity between the BOT-2 and MABC-2 when completed by typically developing school-aged children aged 7–16 years. Method: A convenience sample of 50 children aged 7–16 years with no history of motor or intellectual impairments was recruited. Scores from the BOT-2 and MABC-2 were analysed using Spearman’s rho correlation. Results:The study found that the MABC-2 11- to 16-year-old group (age band 3) was significantly associated with the BOT-2; however, there were no significant relationships between the MABC-2 7- to 10-year-old group (age band 2) and the BOT-2. Conclusion: The MABC-2 and BOT-2 appear to assess associated motor skill abilities in children aged 11–16 years but not in children aged 7–10. This study adds to the body of convergent validity evidence regarding the MABC-2 and BOT-2.
Treatment of orbital vascular malformations with intralesional injection of pingyangmycin

Background To evaluate the safety and efficacy of intralesional pingyangmycin for treatment of orbital vascular malformations. Methods Thirteen patients received intralesional injections of pingyangmycin at the Eye and ENT Hospital of Fudan University. CT scans of each patient were evaluated with graphic processing software to measure lesion volumes before and after treatment. Results Of five men and eight women patients averaging 36 years old, six were diagnosed with venous malformations, six with cavernous haemangiomas, and one with lymphangioma. Proptosis and eyelid swelling were the most common presenting signs. The mean preoperative lesion volume was 4.4±2.3 cm3 (range, 1.6–8.8 cm3), and the average postoperative volume was 1.5±1.7 cm3 (range, 0.2–6.6 cm3) after a single pingyangmycin injection, the dose of which averaged 4.2 mg (range, 2–6 mg). The mean percentage of volume reduction was 70.0% (range, 24.5–88.3%), whereas proptosis reduction averaged 3.2 mm (range, 0–5.5 mm). The lesion volume and proptosis reductions were both statistically significant (p<0.001, and p=0.001). No adverse local or systemic side effects occurred in any of the patients during follow-up averaging 13.3 months. Histopathology of a cavernous haemangioma that underwent a second injection through a surgical incision, showed a mild chronic inflammatory response, increased numbers of myofibroblasts, loss of vascularity and fibrosis, all consistent with known effects of bleomycin treatment. Conclusions Intralesional injection of pingyangmycin for the treatment of orbital vascular malformations is an effective method that involves mild inflammation, fibrosis, and reduced vascularity of the malformation.
Assessment of Body Composition and Breast Milk Volume in Lactating Mothers in Pastoral Communities in Pokot, Kenya, Using Deuterium Oxide

Background: In sub-Saharan Africa, the practice of breast-feeding infants is common. Records documenting the intake of breast milk amongst infants are limited. This study evaluated the association between maternal body composition and the intake of breast milk in infants from the pastoral communities within Pokot, Kenya. Methods: The study was conducted in 10 lactating mothers who were participating in a longitudinal study aimed at determining maternal body composition, iron stores and vitamin A status during the third trimester pregnancy and four months after they had given birth. Maternal and infant anthropometric measurements were made, and maternal blood samples were taken to determine serum retinol and ferritin levels. Infant milk intake and maternal fat-free mass (FFM) and percent body fat (% BF) were measured using ‘the dose to the mother method’. A measured deuterium oxide (2H2O) dose was given to the mother. Urine and breast milk from the mother, and saliva samples from the infant, were collected on days 1, 8 and 14 after dosing. Results: The mean (± SD) maternal mid upper arm circumference (MUAC) and body mass index (BMI) were 21.8 (0.9) cm and 18.6 (1.0) kg/height (m2), respectively. Infant weight and weight/age Z score were 4.956 (0.874) kg and –1.750 (0.77), respectively. Throughout the study, the infants gained 20 (4) g/day in body weight and had a milk intake of 555 (22) ml/day. The energy intake of the infant was 1,602 (148) kJ/day and was lower (p < 0.05) than the 2,404 (423) kJ/day estimated requirement by the FAO/WHO/UNU. The maternal FFM, %BF, Hb, Hct, ferritin and retinol were 32.8 (3.1) kg, 17.24 (7.0), 11.5 (1.3) g/dl, 33.9 (4.9), 16.2 (0.1) µg/l and 0.894 (0.16) µmol/l, respectively. Infant milk intake was significantly and positively correlated to maternal pregnancy triceps (r = 0.679) p < 0.05) and pregnancy MUAC (r = 0.725) p < 0.05). Maternal pregnancy MUAC was an important predictor of infant breast milk intake. Conclusion: Data on volume of breast milk consumed by the infants suggests, at least for this group of infants, that adequate growth may not be achieved. There is a possibility that lactating mothers practicing exclusive breast-feeding and living under harsh conditions may experience periods of low breast milk volume. Body composition and biochemical findings among this group of Pokot mothers indicate dietary inadequacies that require nutritional intervention.
The phenology of leaf quality and its within‐canopy variation is essential for accurate modeling of photosynthesis in tropical evergreen forests

Leaf quantity (i.e., canopy leaf area index, LAI), quality (i.e., per‐area photosynthetic capacity), and longevity all influence the photosynthetic seasonality of tropical evergreen forests. However, these components of tropical leaf phenology are poorly represented in most terrestrial biosphere models (TBMs). Here, we explored alternative options for the representation of leaf phenology effects in TBMs that employ the Farquahar, von Caemmerer & Berry (FvCB) representation of CO2 assimilation. We developed a two‐fraction leaf (sun and shade), two‐layer canopy (upper and lower) photosynthesis model to evaluate different modeling approaches and assessed three components of phenological variations (i.e., leaf quantity, quality, and within‐canopy variation in leaf longevity). Our model was driven by the prescribed seasonality of leaf quantity and quality derived from ground‐based measurements within an Amazonian evergreen forest. Modeled photosynthetic seasonality was not sensitive to leaf quantity, but was highly sensitive to leaf quality and its vertical distribution within the canopy, with markedly more sensitivity to upper canopy leaf quality. This is because light absorption in tropical canopies is near maximal for the entire year, implying that seasonal changes in LAI have little impact on total canopy light absorption; and because leaf quality has a greater effect on photosynthesis of sunlit leaves than light limited, shade leaves and sunlit foliage are more abundant in the upper canopy. Our two‐fraction leaf, two‐layer canopy model, which accounted for all three phenological components, was able to simulate photosynthetic seasonality, explaining ~90% of the average seasonal variation in eddy covariance‐derived CO2 assimilation. This work identifies a parsimonious approach for representing tropical evergreen forest photosynthetic seasonality in TBMs that utilize the FvCB model of CO2 assimilation and highlights the importance of incorporating more realistic phenological mechanisms in models that seek to improve the projection of future carbon dynamics in tropical evergreen forests.
Monitoring of Cerebral Blood Flow and Metabolism Bedside in Patients with Subarachnoid Hemorrhage – A Xenon-CT and Microdialysis Study

Cerebral ischemia is the leading cause of morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH). Although 70% of the patients show angiographic vasospasm only 30% develop symptomatic vasospasm defined as delayed cerebral ischemia (DCI). Early detection and management of reversible ischemia is of critical importance in patients with SAH. Using a bedside Xenon enhanced computerized tomography (Xenon-CT) scanner makes it possible to measure quantitative regional Cerebral blood flow (CBF) bedside in the neurointensive care setting and intracerebral microdialysis (MD) is a method that offers the possibility to monitor the metabolic state of the brain continuously. Here, we present results from nine SAH patients with both MD monitoring and bedside Xenon-CT measurements. CBF measurements were performed within the first 72 h following bleeding. Six out of nine patients developed DCI at a later stage. Five out of six patients who developed DCI had initial global CBF below 26 ml/100 g/min whereas one had 53 ml/100 g/min. The three patients who did not develop clinical vasospasm all had initial global CBF above 27 ml/100 g/min. High lactate/pyruvate (L/P) ratio was associated with lower CBF values in the area surrounding the catheter. Five out of nine patients had L/P ratio ≥25 and four of these patients had CBF ≤ 22 ml/100 g/min. These preliminary results suggest that patients with initially low global CBF on Xenon-CT may be more likely to develop DCI. Initially low global CBF was accompanied with metabolic disturbances determined by the MD. Most importantly, pathological findings on the Xenon-CT and MD could be observed before any clinical signs of DCI. Combining bedside Xenon-CT and MD was found to be useful and feasible. Further studies are needed to evaluate if DCI can be detected before any other signs of DCI to prevent progress to infarction.
Treatment Outcome of Bacteremia Due to KPC-Producing Klebsiella pneumoniae: Superiority of Combination Antimicrobial Regimens

ABSTRACT Klebsiella pneumoniae producing Klebsiella pneumoniae carbapenemase (KPC) has been associated with serious infections and high mortality. The optimal antimicrobial therapy for infection due to KPC-producing K. pneumoniae is not well established. We conducted a retrospective cohort study to evaluate the clinical outcome of patients with bacteremia caused by KPC-producing K. pneumoniae. A total of 41 unique patients with blood cultures growing KPC-producing K. pneumoniae were identified at two medical centers in the United States. Most of the infections were hospital acquired (32; 78%), while the rest of the cases were health care associated (9; 22%). The overall 28-day crude mortality rate was 39.0% (16/41). In the multivariate analysis, definitive therapy with a combination regimen was independently associated with survival (odds ratio, 0.07 [95% confidence interval, 0.009 to 0.71], P = 0.02). The 28-day mortality was 13.3% in the combination therapy group compared with 57.8% in the monotherapy group (P = 0.01). The most commonly used combinations were colistin-polymyxin B or tigecycline combined with a carbapenem. The mortality in this group was 12.5% (1/8). Despite in vitro susceptibility, patients who received monotherapy with colistin-polymyxin B or tigecycline had a higher mortality of 66.7% (8/12). The use of combination therapy for definitive therapy appears to be associated with improved survival in bacteremia due to KPC-producing K. pneumoniae.
