WAIFR: web-browsing attention recorder based on a state-transition model

This paper presents a model for a software component that monitors a user's interaction with a computer system and distributes summaries of that interaction to remote repositories. We illustrate the model with a prototype, implemented as a Web browser extension, for recording temporal aspects of Web browsing, such as time spent reading a page or keeping it open. To give the user control over privacy exposure and network resource usage that are inherent in remote monitoring, our design allows the user to specify how detailed the summaries are and who they are sent to.
Context-based Multi-Document Summarization using Fuzzy Coreference Cluster Graphs

Constructing focused, context-based multi-document summaries requires an analysis of the context questions, as well as their corresponding document sets. We present a fuzzy cluster graph algorithm that finds entities and their connections between context and documents based on fuzzy coreference chains and describe the design and implementation of the ERSS summarizer implementing these ideas.
On the Effects of CPU Caches on MPI Point-to-Point Communications

Several researchers investigated the placing of communication calls in message-passing parallel codes. The current rule of thumb it to maximize communication/computation overlap with early binding. In this work, we demonstrate that this is not the only design constraint because CPU caches can have a significant impact on communications. We conduct an empirical study of the interaction between CPU caching and communications for several different communication scenarios. We use the gained insight to formulate a set of intuitive rules for communication call placement and show how our rules can be applied to practical codes. Our optimized codes show an improvement of up to 40% for a simple stencil code. Our work is a first step towards communication optimizations by moving communication calls. We expect that future communication-aware compilers will use our insights as a standard technique to move communication calls in order to optimize performance.
Cerebral energetics and the glycogen shunt: Neurochemical basis of functional imaging

Positron-emission tomography and functional MRS imaging signals can be analyzed to derive neurophysiological values of cerebral blood flow or volume and cerebral metabolic consumption rates of glucose (CMRGlc) or oxygen (CMRO2). Under basal physiological conditions in the adult mammalian brain, glucose oxidation is nearly complete so that the oxygen-to-glucose index (OGI), given by the ratio of CMRO2/CMRGlc, is close to the stoichiometric value of 6. However, a survey of functional imaging data suggests that the OGI is activity dependent, moving further below the oxidative value of 6 as activity is increased. Brain lactate concentrations also increase with stimulation. These results had led to the concept that brain activation is supported by anaerobic glucose metabolism, which was inconsistent with basal glucose oxidation. These differences are resolved here by a proposed model of glucose energetics, in which a fraction of glucose is cycled through the cerebral glycogen pool, a fraction that increases with degree of brain activation. The “glycogen shunt,” although energetically less efficient than glycolysis, is followed because of its ability to supply glial energy in milliseconds for rapid neurotransmitter clearance, as a consequence of which OGI is lowered and lactate is increased. The value of OGI observed is consistent with passive lactate efflux, driven by the observed lactate concentration, for the few experiments with complete data. Although the OGI changes during activation, the energies required per neurotransmitter release (neuronal) and clearance (glial) are constant over a wide range of brain activity.
Rainwater harvesting knowledge and practice for agricultural production in a changing climate: A review from Uganda’s perspective

With a changing climate in Uganda, rainfall distribution patterns have become more irregular over time and space. Excess water during rainy season is causing runoff, soil erosion, nutrient depletion and crop damage which reduce the productive capacity of land, while on the other hand, prolonged droughts during the crop growing period have become common occurrences. Additionally, pastoralists lose livestock during the dry period each year in the Cattle Corridor of Uganda due to water shortage and lack of forage. It thus remains difficult to achieve the agricultural development targets identified in the National Development Plan for Uganda, without addressing regular incidences of adverse impacts of climate change. Currently there are no well explained approaches which can contribute to adoption of technologies like rainwater management systems which are crucial in enhancing crop yields and livestock production during periods of water shortage. The overarching objective of this paper was to carry out an assessment of the status, performance, and scope for improving rainwater harvesting (RWH) for small-scale agriculture under local conditions. Accordingly, research gaps in RWH technologies were identified and documented to inform future studies. The research was carried out in the semi-arid areas of Nakasongola, Rakai, and Hoima Districts characterized by crop-livestock dependent livelihoods. Findings show that RWH Technologies can enable smallholder farmers and agro-pastoralists to become more resilient to increasing climate variability and climate change by conserving soil and water thus increasing food production and enhancing food security. Small-scale irrigation systems have enabled farmers adapt to drought challenges by enhancing crop yields and allowing farmers to target for higher market prices usually associated with the effects of drought. However, there are challenges including threats to sustainability of such established systems because of lack of community participation in systems’ monitoring and maintenances, and vandalism, and some systems require high investment costs.
Improved error localization in DSL systems based on the common mode

We propose a scheme to improve system performance in Discrete MultiTone systems, which combines the joint differential and common mode processing at the receiver side with erasure marking. This is achieved by using the strong correlation between differential and common mode in the case of a few strong interferers to obtain an estimate of the impulse noise or RFI, which is used for error localization before decoding. When side information is available, a Reed Solomon (RS) decoder is able to correct twice as many erasures than errors.
Correlations Between Cutaneous Malignant Melanoma and Other Cancers: An Ecological Study in Forty European Countries

Background: The presence of noncutaneous neoplasms does not seem to increase the risk of cutaneous malignant melanoma; however, it seems to be associated with the development of other hematological, brain, breast, uterine, and prostatic neoplasms. An ecological transversal study was conducted to study the geographic association between cutaneous malignant melanoma and 24 localizations of cancer in forty European countries. Methods: Cancer incidence rates were extracted from GLOBOCAN database of the International Agency for Research on Cancer. We analyzed the age-adjusted and gender-stratified incidence rates for different localizations of cancer in forty European countries and calculated their correlation using Pearson's correlation test. Results: In males, significant correlations were found between cutaneous malignant melanoma with testicular cancer (r = 0.83 [95% confidence interval (CI): 0.68–0.89]), myeloma (r = 0.68 [95% CI: 0.46–0.81]), prostatic carcinoma (r = 0.66 [95% CI: 0.43–0.80]), and non-Hodgkin lymphoma (NHL) (r = 0.63 [95% CI: 0.39–0.78]). In females, significant correlations were found between cutaneous malignant melanoma with breast cancer (r = 0.80 [95% CI: 0.64–0.88]), colorectal cancer (r = 0.72 [95% CI: 0.52–0.83]), and NHL (r = 0.71 [95% CI: 0.50–0.83]). Conclusions: These correlations call to conduct new studies about the epidemiology of cancer in general and cutaneous malignant melanoma risk factors in particular.
Finding Feasible Parameter Sets for Shape from Silhouettes with Unknown Position of the Viewpoints

Reconstructing 3D shapes from 2D silhouettes is a common technique in computer vision. It requires knowing the position of the viewpoints with respect to the object. But what can we say when this information is not available? This paper provides a first insight into the problem, introducing the problem of understanding 3D shapes from silhouettes when the relative. positions of the viewpoints are unknown. In particular, the case of orthographic silhouettes with viewing directions parallel to the same plane is thoroughly discussed. Also we introduce sets of inequalities, which describe all the possible solution sets and a paving technique to calculate the feasible solution space of each set
A study on third party component reuse in Java enterprise open source software

Recent studies give empirical evidence that much of today's software is to a large extent built on preexisting software, such as commercial-off-the-shelf (COTS) and open source software components. In this exploratory study we want to contribute to this small but increasing body of knowledge by investigating third party component reuse in 36 Java web applications that are open source and are meant to be used in an enterprise context. Our goal is to get a better understanding on how third party components are reused in web applications and how to better support it. The results are in line with existing research in this field. 70 third party components are being reused on average. 50 percent of the 40 most reused third party components are maintained by the Apache Foundation. Further research questions based on the study results were generated and are presented at the end of this paper.
Anticancer activity of taraxerol acetate in human glioblastoma cells and a mouse xenograft model via induction of autophagy and apoptotic cell death, cell cycle arrest and inhibition of cell migration

The aim of the present study was to investigate the in vitro and in vivo anticancer and apoptotic effects of taraxerol acetate in U87 human glioblastoma cells. The effects on cell cycle phase distribution, cell cycle-associated proteins, autophagy, DNA fragmentation and cell migration were assessed. Cell viability was determined using the MTT assay, and phase contrast and fluorescence microscopy was utilized to determine the viability and apoptotic morphological features of the U87 cells. Flow cytometry using propidium iodide and Annexin V-fluorescein isothiocyanate demonstrated the effect of taraxerol acetate on the cell cycle phase distribution and apoptosis induction. Western blot analysis was performed to investigate the effect of the taraxerol acetate on cell cycle-associated proteins and autophagy-linked LC3B-II proteins. The results demonstrated that taraxerol acetate induced dose- and time-dependent cytotoxic effects in the U87 cells. Apoptotic induction following taraxerol acetate treatment was observed and the percentage of apoptotic cells increased from 7.3% in the control cells, to 16.1, 44.1 and 76.7% in the 10, 50 and 150 µM taraxerol acetate-treated cells, respectively. Furthermore, taraxerol acetate treatment led to sub-G1 cell cycle arrest with a corresponding decrease in the number of S-phase cells. DNA fragments were observed as a result of the gel electrophoresis experiment following taraxerol acetate treatment. To investigate the inhibitory effects of taraxerol acetate on the migration of U87 cell, a wound healing assay was conducted. The number of cells that migrated to the scratched area decreased significantly following treatment with taraxerol acetate. In addition, taraxerol acetate inhibited tumor growth in a mouse xenograft model. Administration of 0.25 and 0.75 µg/g taraxerol acetate reduced the tumor weight from 1.2 g in the phosphate-buffered saline (PBS)-treated group (control) to 0.81 and 0.42 g, respectively. Similarly, 0.25 and 0.75 µg/g taraxerol acetate injection reduced the tumor volume from 1.3 cm3 in the PBS-treated group (control) to 0.67 and 0.25 cm3, respectively.
Histopathologic observations on late oral implant failures.

BACKGROUND Despite good success rates of osseointegrated oral implants, failures do occur. To minimize losses, failure mechanisms should be elucidated. PURPOSE This study sought to describe the morphology of tissues surrounding late failed Brånemark implants in relation to their clinical and radiographic findings to acquire a better understanding of the etiologic factors. MATERIAL AND METHODS Ten failed implants and their surrounding tissues were consecutively retrieved from nine patients after prosthesis placement (late losses). On radiographs, a radiolucent line was visible around nine clinically mobile implants. Tightening of the abutment screw evoked pain at seven mobile implants. Clinically, no other visual inflammatory sign or symptom was manifest. A fistula originated from one stable implant, surrounded on radiographs by a diffuse bone rarefaction. Retrieved implants were electrochemically dissolved. Intact tissue-implant thin (1 micron) and ultrathin (70-80 nm) sections were analyzed with light and transmission electron microscopy. RESULTS Peri-implant marginal tissues displayed moderate inflammatory infiltrates located adjacent to and beneath the junctional epithelium. One patient affected by oral lichen planus displayed an intense lymphocyte/plasma cell-dominated immune reaction. Deep peri-implant tissues surrounding mobile implants consisted of a dense, fibrous tissue capsule with minimal inflammation. Epithelial downgrowth was observed around four implants. Small areas of nonmineralized bone in contact with the implant were noticed in the apical portion of two implants. One implant was almost entirely colonized by bacterial plaque with the exception of its apical portion, where bone-implant contact was observed. The stable implant was characterized by bone-implant contact. CONCLUSION Altogether clinical, radiographic, and histologic findings indicated that two major etiologic factors might have been implicated in the failure process of the investigated implants: excessive occlusal load in relation to the bone-supporting capacity and, in two cases, infection.
Effects of Incremental Infusions of Atrial Natriuretic Factor on Aldosterone, Renin, and Blood Pressure in Humans

To evaluate the physiological effects of human atrial natriuretic factor- (99–126) (ANF), we infused ANF, 0.1, 0.3, and 1.0 μ/min, or placebo for 125 minutes on different days into six sodium-deprived normal men. During the last 45 minutes of infusion, angiotensin II, 6 μ/kg/min, was infused. Blood pressure, heart rate, plasma concentrations of ANF, aldosterone, and cortisol, and plasma renin activity (PRA) were measured before and during infusion. Steady state mean plasma ANF levels during infusion were 26.2 (placebo), 68.8 (0.1 μ ANF/min), 221 (0.3 μ ANF/min), and 648 pg/ml (1.0 μ ANF/min). Systolic blood pressure fell significantly (with 1.0 μ ANF/min), and diastolk pressure tended to rise in a dose-dependent manner, while heart rate was unchanged. PRA and plasma aldosterone fell during ANF infusion in a dose-dependent manner (significant with 0.3 and 1.0 fig ANF/min infused). The blood pressure-raising and aldosterone-stimulating effects of angiotensin II were blunted by ANF significant only with 1.0 μ ANF/min). It is concluded that effects of ANF on blood pressure and the renin-aldosterone system occur with plasma ANF levels dose to the phystologkal range, as well as with slightly elevated ANF levels, as observed in congestive heart failure and renal insufficiency.
A Systematic Approach to Evaluate Herb-Drug Interaction Mechanisms: Investigation of Milk Thistle Extracts and Eight Isolated Constituents as CYP3A Inhibitors

Despite increasing recognition of potential untoward interactions between herbal products and conventional medications, a standard system for prospective assessment of these interactions remains elusive. This information gap was addressed by evaluating the drug interaction liability of the model herbal product milk thistle (Silybum marianum) with the CYP3A probe substrate midazolam. The inhibitory effects of commercially available milk thistle extracts and isolated constituents on midazolam 1′-hydroxylation were screened using human liver and intestinal microsomes. Relative to vehicle, the extract silymarin and constituents silybin A, isosilybin A, isosilybin B, and silychristin at 100 μM demonstrated >50% inhibition of CYP3A activity with at least one microsomal preparation, prompting IC50 determination. The IC50s for isosilybin B and silychristin were ∼60 and 90 μM, respectively, whereas those for the remaining constituents were >100 μM. Extracts and constituents that contained the 1,4-dioxane moiety demonstrated a >1.5-fold shift in IC50 when tested as potential mechanism-based inhibitors. The semipurified extract, silibinin, and the two associated constituents (silybin A and silybin B) demonstrated mechanism-based inhibition of recombinant CYP3A4 (KI, ∼100 μM; kinact, ∼0.20 min−1) but not microsomal CYP3A activity. The maximum predicted increases in midazolam area under the curve using the static mechanistic equation and recombinant CYP3A4 data were 1.75-fold, which may necessitate clinical assessment. Evaluation of the interaction liability of single herbal product constituents, in addition to commercially available extracts, will enable elucidation of mechanisms underlying potential clinically significant herb-drug interactions. Application of this framework to other herbal products would permit predictions of herb-drug interactions and assist in prioritizing clinical evaluation.
MEDIUM-TERM FOLLOW-UP RESULTS WITH LAPAROSCOPIC SLEEVE GASTRECTOMY

Background : The indications for sleeve gastrectomy in the surgical treatment of morbid obesity have increased worldwide. Despite this, several aspects related to results at medium and long term remain in constant research. Aim : To present the experience of sleeve gastrectomy in a center of excellence in bariatric surgery by analyzing clinical outcomes, complications and follow-up in the medium term. Methods : The study included 120 morbidly obese patients who underwent sleeve gastrectomy and who were followed for at least 24 months. Aspects related to surgical technique, surgical complications and clinical outcome were analyzed. Results : Seventy-five patients were women (62.5%) and the average age was 36 years. The body mass index preoperatively ranged from 35.5 to 58 kg/m2(average of 40.2 kg/m2). The length of stay ranged from 1 to 4 days (mean 2.1 days). Comorbidities observed were hypertension (19%), type 2 diabetes mellitus (6.6%), dyslipidemia (7.5%), sleep apnea (16.6%), reflux esophagitis (10%) and orthopedic diseases (7.5%). The mean body mass index and total weight loss percentage with 3, 12, 18 and 24 months were 32.2 kg/m2-19,9%; 29.5 kg/m2-26,5%; 28.2 kg/m2-30,3% and 26.9 kg/m2-32,7%, respectively. Remission of diabetes and dyslipidemia occurred in all patients. In relation to hypertension, there was improvement or remission in 86%. There were only two complications (bronchial pneumonia and dehydration), with good response to clinical treatment. There was no evidence digestive fistula and mortality was zero. Eleven patients (9.1%) had regained weighing more than 5 kg. Conclusion : The sleeve gastrectomy is surgical technique that has proven safe and effective in the surgical treatment of obesity and control of their comorbidities in postoperative follow-up for two years.
Teaching and control of robot contour-tracking using contact point detection

New methods for teaching and controlling contour-tracking tasks based on contact sensing are developed to improve robotic machining. Accurate contact point detection is introduced to estimating a work contour path with high reliability. These teaching methods reduce the effort for task teaching and improve adaptability to handle changes in task specifications without re-teaching. Real-time contour tracking control using this contact sensing to suppress work uncertainties in process is presented. Experimental results for practical grinding tasks using a 6 DOF manipulator validate our methods. <<ETX>>
Iso-dielectric cell Separation

Increased throughput in the techniques used to engineer new metabolic pathways in unicellular organisms demands similarly high throughput tools for measuring the effects of these pathways on phenotype. For example, the metabolic engineer is often faced with the challenge of selecting the one genomic perturbation that produces a desired result out of tens of thousands of possibilities [1]. We propose a separation method – iso-dielectric separation, or IDS – which separates microorganisms continuously based on their intrinsic dielectric properties [2-3]. Because IDS is an equilibrium method, sorting cells according to their unique equilibrium positions in an energy landscape, it offers enhanced specificity over other label-free separation methods [4]. This technology would enable high throughput screening of cells based upon electrically distinguishable phenotypes.
Deciphering the system of a systematic review

All clinical decisions and research essentially begins with the review of pre-existing literature. It helps to make our clinical decisions based on an overview of all the literature concerning the particular clinical problem. This requires a lot of time and effort, which is becoming scarce in this day and age. Literature reviews shorten the time by offering relevant evidence in a concise form. However, narrative reviews might not be objective and unbiased. This drawback is overcome by systematic reviews. There is still some apprehension regarding undertaking systematic reviews due to lack of information. This article is an attempt to explain the concept of systematic reviews and methods used for conducting the same, which will be helpful in day-to- day clinical practice as well as research.
Monitoring and Detecting of Air Pollution using Wireless Sensors Network

In recent technological developments in the wireless communication technology have to the emergence of environmental pollution sensor and air pollution sensor network.it is monitoring system provides real time information about the level of air pollution particular region. Lacks of implementation of environmental regulation are contributing to the bad air quality of most of the Indian cities. Analytical measuring equipment is costly, time and power consuming, and can seldom be used for air quality reporting in real time. Wireless Sensor Networks are a new and very challenging research field for embedded system design automation, as their design must enforce stringent constraints in terms of power and the problem of air pollution is becoming a major concern for the health of pollution and all sector of our life and identify the approach in various application like leakage of gas industry and oil sector. I can also calculate the better power management and real time measuring and monitoring in an urban area to ultimately improve quality of life on earth. Air pollution in the urban environment is a major threat to human health. As the global population is becoming more concentrated in urbanized areas, new ideas and approaches are needed to help maintain clean air that is safe for everyone to breathe. I propose a indoor and outdoor air pollution monitoring system which uses ZigBee and ARIMA prediction model for monitoring air pollution. It predicts the carbon dioxide level in ubiquitous cities and system integrates wireless sensor board and also integrates with the dust, temperature and humidity and reducing power consumpution. In this module is the small range, low power, low data rate wireless networking technology for many wireless
