On-the-Fly Adaptation of Regression Forests for Online Camera Relocalisation

Camera relocalisation is an important problem in computer vision, with applications in simultaneous localisation and mapping, virtual/augmented reality and navigation. Common techniques either match the current image against keyframes with known poses coming from a tracker, or establish 2D-to-3D correspondences between keypoints in the current image and points in the scene in order to estimate the camera pose. Recently, regression forests have become a popular alternative to establish such correspondences. They achieve accurate results, but must be trained offline on the target scene, preventing relocalisation in new environments. In this paper, we show how to circumvent this limitation by adapting a pre-trained forest to a new scene on the fly. Our adapted forests achieve relocalisation performance that is on par with that of offline forests, and our approach runs in under 150ms, making it desirable for real-time systems that require online relocalisation.
Phosphate solubilizing bacteria: assessment of their effect on growth promotion and phosphorous uptake of mung bean (Vigna radiata [L.] R. Wilczek)

The aim of this work was to isolate phosphate solubilizing bacteria (PSB) and assess their effect on the growth of mung bean ( Vigna radiata [L.] R. Wilczek) plants. Of 31 isolated PSB strains, two efficient strains, identified as Pantoea agglomerans (PSB-1) and Burkholderia anthina (PSB-2), were employed in further studies. Maximum P solubilization (720.75 μg mL-1) was recorded from the cultures co-inoculated with P. agglomerans and B. anthina. A strong positive correlation was found between pH and soluble P concentration in the medium, as well as between titratable acidity and P solubilization. Both strains under greenhouse conditions remarkably enhanced shoot and root length, shoot and root dry matter, and P uptake of mung bean plants. Growth was found to be further improved by adding tricalcium phosphate (TCP) with PSB inoculation. Co-inoculation of both PSB strains and adding TCP exhibited the highest growth performances and P uptake of mung bean plants; this implies that their applicability as a promising alternative to minimize the P problem in agricultural soils.
What Makes Deeply Encoded Items Memorable? Insights into the Levels of Processing Framework from Neuroimaging and Neuromodulation

When we form new memories, their mnestic fate largely depends upon the cognitive operations set in train during encoding. A typical observation in experimental as well as everyday life settings is that if we learn an item using semantic or “deep” operations, such as attending to its meaning, memory will be better than if we learn the same item using more “shallow” operations, such as attending to its structural features. In the psychological literature, this phenomenon has been conceptualized within the “levels of processing” framework and has been consistently replicated since its original proposal by Craik and Lockhart in 1972. However, the exact mechanisms underlying the memory advantage for deeply encoded items are not yet entirely understood. A cognitive neuroscience perspective can add to this field by clarifying the nature of the processes involved in effective deep and shallow encoding and how they are instantiated in the brain, but so far there has been little work to systematically integrate findings from the literature. This work aims to fill this gap by reviewing, first, some of the key neuroimaging findings on the neural correlates of deep and shallow episodic encoding and second, emerging evidence from studies using neuromodulatory approaches such as psychopharmacology and non-invasive brain stimulation. Taken together, these studies help further our understanding of levels of processing. In addition, by showing that deep encoding can be modulated by acting upon specific brain regions or systems, the reviewed studies pave the way for selective enhancements of episodic encoding processes.
The reach, transferability, and impact of the Evidence-Based Practice Questionnaire: a methodological and narrative literature review.

BACKGROUND Since the 1990s, evidence-based practice (EBP) has been increasingly emphasized in nursing, but its implementation is still sometimes met with confusion and resistance. Therefore, identifying factors affecting its implementation is crucial. The Evidence-Based Practice Questionnaire (EBPQ) was published in 2006, addressing a need for a robust measure of nurses' practice of, attitudes toward, and knowledge of EBP. The growing body of professionals using the questionnaire means that a review of its reach, transferability, and impact is timely. AIMS The aims of this review were threefold: (a) identify the situations in which the EBPQ has been used in both published and unpublished research internationally (Reach); (b) collate the psychometric properties of the EBPQ from the research reviewed (Transferability); and (c) discuss the study's findings to shed new light on issues facing professionals in implementing EBP, and possible future directions for research (Impact). METHODS Literature searches on studies reported between 2006 and July 2012 inclusive were conducted using the terms "Evidence-Based Practice Questionnaire" and "EBPQ. " Green, Johnson and Adams's guidelines for completing narrative literature reviews and Terwee et al.'s framework for reporting questionnaires' psychometric properties were adopted to ensure rigor. FINDINGS Twenty-seven studies were reviewed in which the EBPQ had been translated into five different languages and used with a variety of professional groups. The questionnaire demonstrated convergent and discriminant validity and good internal reliability. Research adopting the questionnaire identified a range of variables related to EBP implementation, including qualification route and job role. LINKING EVIDENCE TO ACTION Assessment of organizational culture and workforce training needs prior to developing educational interventions is crucial. The EBPQ has the potential to provide further understanding of these and other issues faced by professionals when implementing EBP.
The Impending Loss of Talent: An Exploratory Study Challenging Assumptions about Testing and Merit

Using five different data sets, this study explores the bidirectional relationship between standardized tests and various indicators of success. Examining student success on a variety of indicators such as cumulative grade point average and graduation rates, the study demonstrates the limited usefulness of such tests, particularly when the data are disaggregated by gender or race and ethnicity. Overall, if tests are overemphasized in the admissions context, they can contribute to a significant loss of talent.
The effect of spiral arms on star formation in the Galaxy

We have examined the ratio between the integrated luminosity of massive young stellar objects detected by the Red MSX Source (RMS) survey and the mass of molecular clouds in the Galactic Ring Survey (GRS) region, as a function of Galactocentric radius. The results indicate that 60-80per cent of the observed increases in the star formation rate density associated with spiral-arm features are due to source crowding within the arms. Of the remainder, most of the increase in the inner Sagittarius arm is due to an enhancement in the simple star formation efficiency, i.e. in the number of RMS sources per unit molecular gas mass. In the inner Perseus arm, the residual increase is due to a higher than average mean source luminosity, which implies a top-heavy initial mass function, and this is entirely due to the presence, in the GRS region, of the W49 star-forming complex, which appears to be exceptional in its nature. The results also suggest that there is little or no increase in the star formation efficiency on kiloparsec scales in the Scutum tangent region which includes W43. We discuss the possible role played by the spiral arms in influencing the star formation efficiency and conclude that the most likely mechanisms are related to orbit crowding within the arms. © 2012 The Authors Monthly Notices of the Royal Astronomical Society © 2012 RAS.
Bacterial infection as an adverse effect of telaprevir-based triple therapy for chronic hepatitis C infection.

OBJECTIVE There is little information regarding the incidence of bacterial infections as an adverse effect of telaprevir (TVR)-based triple therapy. This study was performed in order to evaluate the baseline and on-treatment predictors of bacterial infections in patients treated with TVR-based triple therapy. METHODS This multicenter study evaluated 430 patients with chronic hepatitis C who received 12 weeks of TVR in combination with 24 weeks of pegylated interferon α2b plus ribavirin. The occurrence of a bacterial infection during anti-viral treatment was defined as the onset of local or systemic inflammation as a result of pathogenic bacteria. RESULTS Bacterial infections occurred in 21 of the 430 (4.9%) patients during TVR-based triple therapy. Among these subjects, 71.4% (15 of 21) experienced bacterial infections during the initial eight weeks of treatment. Urinary tract infections were the most frequent infection, observed in 2.8% of cases (12 of 430). The rate of urinary tract infection among women (11 of 215, 5.1%) was significantly higher than that observed among men (1 of 215, 0.5%) (p<0.0001). According to a multivariable logistic regression analysis, the only significant independent predictor was the pretreatment serum albumin level (p=0.0008). Of the 21 patients who experienced bacterial infections, only one (4.8%) had to discontinue the treatment; however, the others were able to continue anti-viral treatment in combination with antibiotic treatment. CONCLUSION Clinicians should be concerned regarding the incidence of bacterial infections among patients treated with TVR-based triple therapy, especially those with a low serum albumin level.
Can dynamically downscaled windstorm footprints be improved by observations through a probabilistic approach?

Windstorms are a main feature of the European climate and exert strong socioeconomic impacts. Large effort has been made in developing and enhancing models to simulate the intensification of windstorms, resulting footprints, and associated impacts. Simulated wind or gust speeds usually differ from observations, as regional climate models have biases and cannot capture all local effects. An approach to adjust regional climate model (RCM) simulations of wind and wind gust toward observations is introduced. For this purpose, 100 windstorms are selected and observations of 173 (111) test sites of the German Weather Service are considered for wind (gust) speed. Theoretical Weibull distributions are fitted to observed and simulated wind and gust speeds, and the distribution parameters of the observations are interpolated onto the RCM computational grid. A probability mapping approach is applied to relate the distributions and to correct the modeled footprints. The results are not only achieved for single test sites but for an area‐wide regular grid. The approach is validated using root‐mean‐square errors on event and site basis, documenting that the method is generally able to adjust the RCM output toward observations. For gust speeds, an improvement on 88 of 100 events and at about 64% of the test sites is reached. For wind, 99 of 100 improved events and ~84% improved sites can be obtained. This gives confidence on the potential of the introduced approach for many applications, in particular those considering wind data.
Effects of psychosocial interventions with adult cancer patients: a meta-analysis of randomized experiments.

Meta-analytic methods were used to synthesize the results of published randomized, controlled-outcome studies of psychosocial interventions with adult cancer patients. Forty-five studies reporting 62 treatment-control comparisons were identified. Samples were predominantly White, female, and from the United States. Beneficial effect size ds were . 24 for emotional adjustment measures, . 19 for functional adjustment measures, . 26 for measures of treatment- and disease-related symptoms, and . 28 for compound and global measures. The effect size of . 17 found for medical measures was not statistically significant for the few reporting studies. Effect sizes for treatment-control comparisons did not significantly differ among several categories of treatment: behavioral interventions, nonbehavioral counseling and therapy, informational and educational methods, organized social support provided by other patients, and other nonhospice interventions.
The Role of Dopamine and Its Dysfunction as a Consequence of Oxidative Stress

Dopamine is a neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. Dysfunction of the dopamine system has been implicated in different nervous system diseases. The level of dopamine transmission increases in response to any type of reward and by a large number of strongly additive drugs. The role of dopamine dysfunction as a consequence of oxidative stress is involved in health and disease. Introduce new potential targets for the development of therapeutic interventions based on antioxidant compounds. The present review focuses on the therapeutic potential of antioxidant compounds as a coadjuvant treatment to conventional neurological disorders is discussed.
Exploring the narratives of African Caribbean high attaining boys : perceived peer influences in education

The underachievement of African Caribbean boys has been the subject of considerable debate and research in education but few studies focus on this group's achievements. Difficulties associated with racial identity and masculinity are amongst explanations offered for African Caribbean boys' educational underachievement and research has also implicated the peer group's contributions to undermining academic performance. This thesis explores the subjective experiences of high-attaining African Caribbean boys regarding their perceptions of peer influences in school. Seven pupils were given two narrative interviews (2 months apart) about their relationships with peers and experiences related to 'peer influence' and the impact they consider that this has on their education and attainment. Interviews also addressed the impact of family narratives on the boys at school. The interviews were analysed using Gee's (1991) structural linguistic narrative approach, which as well as helping to identify narratives also allowed analysis of how the boys performed their identities in co-constructing their narratives with the interviewer. The findings suggest that the boys perceive peers to have some influence on their educational experiences and subsequent attainment. Narratives espoused the positive aspects of peer relationships as being emotionally and practically supportive and helping boys' motivation to study through competing for high grades. They also highlighted that peer distractions could lead to underachievement. Pupils used multiple and complex strategies to manage their relationships so that they continued to attain well. These included strategic self-presentation, deploying resources (e.g. social capital) and utilising support from teachers and family members. Family racialised narratives were found to play an important role in developing racial identity and academic orientation. The thesis discusses the implications of these findings and critically comments on the use of narrative interviews and analysis in research with young people and its relevance to schools and Educational Psychology practice.
Filamentous structures associated with Epstein-Barr virus-infected cells

After the onset of Epstein-Barr virus DNA and protein synthesis 10 h after superinfection of Raji cells (a cell line containing Epstein-Barr virus DNA but not producing virus), filamentous structures 25 nm in diameter and 0.2 to 1.4 micrometers in length could be detected in the cell cytoplasm by electron microscopy. These structures banded in metrizamide gradients with viral DNA and proteins, but at a density different from that of virions or nucleocapsids. These filaments, enriched in a 155,000-dalton protein similar in size to a major nucleocapsid protein of Epstein-Barr virus, may represent intermediates in viral nucleocapsid assembly.
Data Mining Techniques: To Predict and Resolve Breast Cancer Survivability

Abstract— Breast cancer is one of the deadliest disease, is the most common of all cancers and is the leading cause of cancer deaths in women worldwide, accounting for >1.6% of deaths and case fatality rates are highest in low-resource countries. The breast cancer risks are broadly classified into modifiable and non –modifiable factors. The non modifiable risk factors are age, gender, number of first degree relatives suffering from breast cancer, menstrual history, age at menarche and age at menopause. While the modifiable risk factors are BMI, age at first child birth, number of children, duration of breast feeding, alcohol, diet and number of abortions. This paper presents a diagnosis system for detecting breast cancer based on RepTree, RBF Network and Simple Logistic. In test stage, 10-fold cross validation method was applied to the University Medical Centre, Institute of Oncology, Ljubljana, Yugoslavia database to evaluate the proposed system performances. The correct classification rate of proposed system is 74.5%. This research demonstrated that the Simple Logistic can be used for reducing the dimension of feature space and proposed Rep Tree and RBF Network model can be used to obtain fast automatic diagnostic systems for other diseases. Keywords— Breast cancer survivability; Rep Tree; RBF Network; Simple Logistic; Diagnostic systems
Lack of Direct Cytotoxicity of Extracellular ATP against Hepatocytes: Role in the Mechanism of Acetaminophen Hepatotoxicity.

BACKGROUND Acetaminophen (APAP) hepatotoxicity is a major cause of acute liver failure in many countries. Mechanistic studies in mice and humans have implicated formation of a reactive metabolite, mitochondrial dysfunction and oxidant stress as critical events in the pathophysiology of APAP-induced liver cell death. It was recently suggested that ATP released from necrotic cells can directly cause cell death in mouse hepatocytes and in a hepatoma cell line (HepG2). AIM To assess if ATP can directly cause cell toxicity in hepatocytes and evaluate their relevance in the human system. METHODS Primary mouse hepatocytes, human HepG2 cells, the metabolically competent human HepaRG cell line and freshly isolated primary human hepatocytes were exposed to 10-100 μM ATP or ATγP in the presence or absence of 5-10 mM APAP for 9-24 h. RESULTS ATP or ATγP was unable to directly cause cell toxicity in all 4 types of hepatocytes. In addition, ATP did not enhance APAP-induced cell death observed in primary mouse or human hepatocytes, or in HepaRG cells as measured by LDH release and by propidium iodide staining in primary mouse hepatocytes. Furthermore, addition of ATP did not cause mitochondrial dysfunction or enhance APAP-induced mitochondrial dysfunction in primary murine hepatocytes, although ATP did cause cell death in murine RAW macrophages. CONCLUSIONS It is unlikely that ATP released from necrotic cells can significantly affect cell death in human or mouse liver during APAP hepatotoxicity. RELEVANCE FOR PATIENTS Understanding the mechanisms of APAP-induced cell injury is critical for identifying novel therapeutic targets to prevent liver injury and acute liver failure in APAP overdose patients.
Feature extraction of UHF PD signals by wavelet packet based MRSD analysis For defect identification in Gas Insulated Systems

In condition monitoring of Gas Insulated Systems (GIS) the upcoming failure modes can be diagnosed well ahead by analyzing the Partial Discharge (PD) activity. In recent times, Ultra High Frequency (UHF) technique is recognised as effective tool for online PD analysis. In this paper, a simple and effective wavelet packet based multi-resolution signal decomposition feature extraction scheme is proposed to estimate the spectral energy distribution of UHF signal for PD source location. Further, the relationship between critical frequency components of UHF PD signal generated by different type of defects is investigated. The optimized model is ascertained for common onsite defects called protrusion on electrode, freely moving metallic particle, surface discharge in epoxy spacer, floating particle sitting on the epoxy spacer of compressed SF6 GIS under HVAC. The four defects are modeled in laboratory environment and defect identification with the proposed technique is verified with the minimum success rate of 95% irrespective of physical conditions like, gas pressure, PD severity or defect location.
Biochemical Markers of Cardiac Risk and Their Relation to Spirometric Indices of Airway Obstruction Among COPD Patients

Monitoring of the cardiac status of COPD (Chronic Obstructive Pulmonary Disease) and comparing them with their respiratory indices thought to be predictive markers of the general health of these patients and be indicative, even prognostic, of any impending deterioration. This study was destined to evaluate various aspect of serum prognostic factors in COPD patients. This study was conducted over a period of six months. During this time biochemical markers of 43 (34 male and 9 female) patients suffering from COPD were collected and compared them with those of 40 healthy case control subjects. The Methodology and Exclusion Criteria were strictly adhered to, and based on the statistical analysis shown below the final results were arrived at, which have been discussed at length below. The relation between smoking and COPD found to be controversial, but smoking none the less has a detrimental effect on the respiratory indices and thus, cessation of smoking would definitely benefit these patients, although the extent of the benefit is a matter of debate and further study. As for the individual markers, serum CRP and plasma homocysteine are definitely important as prognostic markers, as well as the indicators of the present stage of the disease. Serum Lipoprotein (a) was not found to be very effective indicator in this study. Homocysteine as well as CRP but not lipoprotein (a), as cardiac indices is inversely related to the respiratory indices of a COPD patient. Measurement of these parameter might help in prognostic evaluation in those patients.
Evaluating Healthcare Claims for Neurocysticercosis by Using All-Payer All-Claims Data, Oregon, 2010–2013

To characterize the frequency of neurocysticercosis, associated diagnostic codes, and place of infection, we searched Oregon’s All Payer All-Claims dataset for 2010–2013. Twice as many cases were found by searching inpatient and outpatient data than by inpatient data alone. Studies relying exclusively on inpatient data underestimate frequency and miss less severe disease.
Kinetics and dynamics of tobramycin action in patients with bacteriuria given single doses

We studied the effect of a single intravenous dose of tobramycin on the rate of bacterial eradication from urine in 10 patients with bladder catheters. The catheter was replaced 4 to 6 h after the tobramycin dose. Pseudomonas aeruginosa was found in 7 of the 10 patients, while members of the family Enterobacteriaceae accounted for the remaining pathogens. The MIC for each bacterium was determined in both broth and urine. Tobramycin eradicated the bacteria from eight patients. Bacteriuria resolved in 21.8 +/- 18.0 h, and urine bactericidal activity persisted for 43.4 +/- 20.3 h after the dose of tobramycin. Most patients were recolonized by another bacterial species if use of Foley catheters was resumed on a continuous basis. Two patients required additional doses of tobramycin to eradicate the original pathogen. There were significant temporal relationships between the pharmacokinetics of tobramycin and the change in colony count of bacteria in urine.
