Spatial Pyramid Context-Aware Moving Object Detection and Tracking for Full Motion Video and Wide Aerial Motion Imagery

A robust and fast automatic moving object detection and tracking system is essential to characterize target object and extract spatial and temporal information for different functionalities including video surveillance systems, urban traffic monitoring and navigation, robotic. In this dissertation, I present a collaborative Spatial Pyramid Context-aware moving object detection and Tracking system. The proposed visual tracker is composed of one master tracker that usually relies on visual object features and two auxiliary trackers based on object temporal motion information that will be called dynamically to assist master tracker. SPCT utilizes image spatial context at different level to make the video tracking system resistant to occlusion, background noise and improve target localization accuracy and robustness. We chose a pre-selected seven-channel complementary features including RGB color, intensity and spatial pyramid of HoG to encode object color, shape and spatial layout information. We exploit integral histogram as building block to meet the demands of real-time performance. A novel fast algorithm is presented to accurately evaluate spatially weighted local histograms in constant time complexity using an extension of the integral histogram method. Different techniques are explored to efficiently compute integral histogram on GPU architecture and applied for fast spatio-temporal median computations and 3D face reconstruction texturing. We proposed a multi-component framework based on semantic fusion of motion information with projected building footprint map to significantly reduce the false alarm rate in urban scenes with many tall structures. The experiments on extensive VOTC2016 benchmark dataset and aerial video confirm that combining complementary tracking cues in an intelligent fusion framework enables persistent tracking for Full Motion Video and Wide Aerial Motion Imagery.
Trends and forecasts of hospital admissions for acute and chronic pancreatitis in the Netherlands

Background The incidence and prevalence of acute and chronic pancreatitis have increased in Western countries. It is likely, the number of hospital admissions has increased correspondingly. Aims To analyze the trends in hospital admissions in the Netherlands for acute and chronic pancreatitis from 1992 to 2004 and to forecast the number of admissions up to 2010. Methods Analysis of hospital admissions for acute and chronic pancreatitis accumulated in a nationwide database. Curve fitting regression models were used to explore future trends. Results The number of acute pancreatitis admissions rose in 1992–2004 from 1785 to 3120 (74.8% increase). The overall ‘annual number’ of acute pancreatitis admissions increased from 11.8 to 19.2 per 100 000 person-years. The linear regression model predicted 3205 [95% confidence intervals (CI), 3111–3299] and 3537 (95% CI, 3429–3645) admissions for 2007 and 2010, respectively, a further increase of at least 9.9% in 2010 compared with 2004. In the 12-year time period, chronic pancreatitis admissions showed an increase of 75.4% (from 790 to 1386). The overall ‘annual number’ of chronic pancreatitis admissions increased from 5.2 to 8.5 per 100 000 person-years. The cubic regression model predicted 1868 (95% CI, 1619–2117) and 3173 (95% CI, 2456–3890) admissions for 2007 and 2010, respectively, an additional increase of 77.2% in 2010 compared with 2004. Conclusion Hospital admissions for acute and chronic pancreatitis have increased substantially from 1992–2004. This trend will most likely continue for the near future and the burden and costs to the Dutch health care system will increase accordingly.
Effects of clozapine on positive and negative symptoms in outpatients with schizophrenia.

OBJECTIVE Clozapine is an atypical neuroleptic with superior efficacy in severely ill, treatment-resistant inpatients with schizophrenia. To determine if clozapine's differential efficacy generalizes to less ill, outpatients populations, the authors examined the effects of clozapine on positive and negative symptoms in outpatients with schizophrenia. METHOD Outpatients with schizophrenia who had histories of partial response to conventional neuroleptics and who had not responded to a prospective 6-week trial of fluphenazine participated in a 10-week, double-blind, parallel-groups comparison of clozapine and haloperidol. Thirteen men and six women were given clozapine, and 15 men and five women were given haloperidol. Clinical response rates were determined and effects on primary versus secondary negative symptoms were addressed. Doses of clozapine and haloperidol at the end of the 10-week trial were 410.5 mg/day (SD = 45.8) and 24.8 mg/day (SD = 5.5), respectively. RESULTS Clozapine was superior to haloperidol for treating positive symptoms. In addition, eight of the patients given clozapine and only one of the patients given haloperidol fulfilled clinical responder criteria. Clozapine was also superior to haloperidol for treating negative symptoms, although these effects were relatively minor. Negative symptoms were significantly affected in the subgroup of patients with nondeficit schizophrenia but not in the subgroup with deficit schizophrenia. Overall, clozapine was well tolerated. CONCLUSIONS Clozapine has superior efficacy for treating positive symptoms in partially responsive outpatients with chronic schizophrenia, suggesting that it has utility for a broad spectrum of patients with schizophrenia beyond the most severely ill.
HYPERVELOCITY STARS AND THE RESTRICTED PARABOLIC THREE-BODY PROBLEM

Motivated by detections of hypervelocity stars that may originate from the Galactic center, we revisit the problem of a binary disruption by a passage near a much more massive point mass. The six orders of magnitude mass ratio between the Galactic center black hole (BH) and the binary stars allows us to formulate the problem in the restricted parabolic three-body approximation. In this framework, results can be simply rescaled in terms of binary masses, their initial separation, and the binary-to-black hole mass ratio. Consequently, an advantage over the full three-body calculation is that a much smaller set of simulations is needed to explore the relevant parameter space. Contrary to previous claims, we show that, upon binary disruption, the lighter star does not remain preferentially bound to the black hole. In fact, it is ejected in exactly 50% of the cases. Nonetheless, lighter objects have higher ejection velocities, since the energy distribution is independent of mass. Focusing on the planar case, we provide the probability distributions for disruption of circular binaries and for the ejection energy. We show that even binaries that penetrate deeply into the tidal sphere of the BH are not doomed to disruption, but survive in 20% of the cases. Nor do these deep encounters produce the highest ejection energies, which are instead obtained for binaries arriving to 0.1–0.5 of the tidal radius in a prograde orbit. Interestingly, such deep-reaching binaries separate widely after penetrating the tidal radius, but always approach each other again on their way out from the BH. Finally, our analytic method allows us to account for a finite size of the stars and recast the ejection energy in terms of a minimal possible separation. We find that, for a given minimal separation, the ejection energy is relatively insensitive to the initial binary separation.
Dancers in the Dark: Scientific Careers According to a Gender-Blind Model of Promotion

AbstractThe disparity between men and women in science is a hot topic in gender studies and a relevant target of scientific policies. The leaky pipeline metaphor illustrates the decreasing number of women along senior positions in academia; however many questions remain unanswered. What factors progressively diminish the number of women in scientific careers and why do they appear to be less successful than their male colleagues? In order to discover new insight, this work compares men’s and women’s career paths by taking into account academic and family milestones achieved throughout the life course. An innovative and interdisciplinary methodology (from bibliometrics, statistics, and sociology) has been constructed to examine men’s and women’s trajectories. Findings display gender differences in scientists’ trajectories. The evolution of scientists’ careers reveals linear careers for males, whilst women develop non-linear careers. Motherhood emerges as a problem for developing linear careers. And collegi.
Fiber connections of the compact division of the posterior pallial amygdala and lateral part of the bed nucleus of the stria terminalis in the pigeon (Columba livia)

The compact division of the posterior pallial amygdala (PoAc) and lateral part of the bed nucleus of the stria terminalis (BSTL) are components of the limbic system in the pigeon brain. In this study, we examined the position and fiber connections of these two nuclei by using Nissl staining and tract‐tracing methods. PoAc occupies a central division in the posterior pallial amygdala. BSTL faces the ventral horn of the lateral ventricle and extends between A 7.25 and A 10.50. PoAc and BSTL connect bidirectionally by the stria terminalis. PoAc connects reciprocally with two nuclear groups in the cerebrum: 1) a continuum consisting of the caudoventral nidopallium, lateral part of the caudoventral nidopallium (NCVl), subnidopallium beneath NCVl, and piriform cortex and 2) rostral areas of the hemisphere, including the frontolateral and frontomedial nidopallium and the densocellular part of the hyperpallium. Extratelencephalic projections of PoAc terminate in the dorsomedial thalamic nuclei and reach the lateral hypothalamic area via the hypothalamic part of the occipito‐mesencephalic tract. BSTL also connects reciprocally with two main regions: 1) the same continuum as for PoAc projections, except the piriform cortex and 2) rostral areas of the hemisphere, including the olfactory tubercle and nucleus accumbens. Extratelencephalic reciprocal connections are with the substantia nigra, nucleus subceruleus dorsalis, parabrachial nucleus, locus coeruleus, and nucleus of the solitary tract. The dorsomedial subdivision of the hippocampal formation projects massively to PoAc and BSTL. These findings indicate that PoAc and BSTL are important components of an interconnected neural circuit involving widespread regions of the neuraxis and mediating limbic‐visceral functions. J. Comp.

Differential immediate-early gene responses to elevated pressure in porcine aortic valve interstitial cells.

BACKGROUND AND AIM OF THE STUDY Cardiovascular risk factors are believed to play a role in the pathogenesis of aortic valve disease. In the present study the hypothesis was proposed that elevated pressure would cause a change in the expression of prototypical pro-inflammatory genes. Hence, the expression of MCP-1, osteopontin (OPN), VCAM-1, GM-CSF and PAI-1 was examined using semi-quantitative real-time RT-PCR. METHODS Porcine aortic valve interstitial cells at passage 1 were exposed to constant pressures of 100, 140, or 170 mmHg or cyclic pressures of 80-120, 120-160, or 150-190 mmHg for 2 h. Static cultures at atmospheric pressure served as controls. Total RNA from pooled experiments was isolated for analysis of gene expression. Single tube primer-mediated RT-PCR was performed directly on the RNA. RESULTS Cells responded differently to constant and cyclic pressure. The most notable response was the expression of OPN, which was significantly up-regulated under steady conditions but down-regulated under cyclic conditions. The opposite was true in VCAM-1 expression, which was significantly down-regulated at 170 mmHg static pressure, but up-regulated at 140 and 170 mmHg mean cyclic pressure. There was no clear proportional correlation between pressure magnitude and expression of MCP-1, GM-CSF, or PAI-1. However, elevated cyclic pressure caused a proportional increase in VCAM-1 expression and a proportional decrease in OPN expression. CONCLUSION Elevated cyclic pressure is a potent stimulus for the up-regulation of VCAM-1 expression and the down-regulation of OPN expression. This demonstrates an association between hypertension and aortic valve stenosis and calcification. The regulation of the chemotactic genes MCP-1 and GM-CSF is not correlated to a change in compressive forces.
Phenomenology of pulsar B0809+74's rotating subbeam system II. "Carousel" configuration and polarization

Building on results and analyses of previous works, the structure and polarization of B0809+74's subbeam "carousel" is delimited, but not fully solved. Some 8-10 subbeams are indicated for an equatorward sightline traverse and 25-40 for a polarward one. Either alternative indicates a subbeam circulation time much longer than predicted by theory. Polarized subbeam maps show complex structure and suggest that the star's polarized modes are angularly disjoint.
Physician workforce data: when the best is not good enough.

In this issue of HSR, the article by Rittenhouse et al. (2004) calls into question two different sources of information about physicians' decisions to leave clinical practice: data from the Physician Masterfile of the American Medical Association (AMA), and physicians' self-reported intentions to leave patient care. The authors conclude that neither source of data provided reliable information on withdrawals from clinical practice. In particular, they find that the AMA Masterfile had a sensitivity of only 9% in detecting physicians who left clinical practice during the previous three years.

Single-crystal neutron diffraction study of metamict zircon up to 2000 K

High-temperature single-crystal measurements of metamict zircon were performed up to 2000 K and the recrystallization was monitored using the width and intensity of selected peaks. Full data sets were collected at room temperature, 1573 and 1823 K. The changes in the probability density function (p.d.f.) of the O atoms revealed important features of the recrystallization. The measurements were done in air using a mirror furnace and performed on the D19 four-circle diffractometer at the ILL equipped with a vertically curved two-dimensional position-sensitive detector.
Human Capital Investments and Expectations about Career and Family

We conducted a survey of high-ability college students and elicited beliefs about how their choice of major, and of whether to complete their degree, would affect an array of future events: earnings, employment, marriage prospects, potential spousal characteristics, and fertility. We find that students perceive large “returns” to human capital not only in their own future earnings but also in other dimensions (e.g., potential spouse’s earnings and fertility). We find evidence of students sorting into majors on the basis of these perceived returns. Family expectations are particularly important for female students’ major choices. In a follow-up survey conducted 6 years after the initial data collection, we find a close connection between expectations and current realizations.
Detection of Mycobacterium bovis in Organs of Slaughtered Cattle by DNA-Based Polymerase Chain Reaction and Ziehl-Neelsen Techniques in Bauchi State, Nigeria

Bovine tuberculosis is a chronic, infectious, and contagious zoonotic disease of domestic animals, wild animals, and humans. It also poses a public health threat and economic losses. This study was aimed at determining the prevalence of bovine tuberculosis in slaughtered cattle, based on PM meat inspection, Ziehl-Neelsen staining, and PCR techniques in Bauchi State, Nigeria. A Prospective study was conducted on 800 cattle slaughtered in the three Zonal abattoirs of Bauchi State, Nigeria. One hundred and twenty (15%) tissues from different organs had suspected bTB lesions at PM. Out of the samples examined 35 (29.2%) were AFB positive by ZN and 10 (8.3%) were confirmed positive for M. bovis by PCR, with an overall prevalence of 29.16% and 8.33%, respectively. Female had a higher prevalence rate than male cattle at 16.66% and 12.5 % by ZN and 5.00% and 3.33% by PCR, respectively (P>0.05, χ 2 = 0.218). However, there was a statistically significant association (P<0.05, χ 2 = 7.002) between detection of bTB and the age of cattle. ZN revealed that cattle aged 6 years and above had the highest number of positive bTB cases 67.9%, while cattle aged 3–5 years had the lowest 14.81%. PCR technique revealed that the cattle aged 6 and above years also had the highest percentage positive M. bovis cases of 22.84%, whereas cattle aged 3–5 years had the lowest and the overall prevalence rate of 8.33%. The study found a high infection rate of bTB among cattle and majority of the lesions 54.2% were from lungs. The prevalence of bTB was higher in Bauchi metropolitan abattoir which supplies larger population of the state with beef.
The Broselow and Handtevy Resuscitation Tapes: A Comparison of the Performance of Pediatric Weight Prediction

Abstract Objectives To assess the performance of two pediatric length-based tapes (Broselow and Handtevy) in predicting actual weights of US children. Methods In this descriptive study, weights and lengths of children (newborn through 13 years of age) were extracted from the 2009-2010 National Health and Nutrition Examination Survey (NHANES). Using the measured length ranges for each tape and the NHANES-extracted length data, every case from the study sample was coded into Broselow and Handtevy zones. Mean weights were calculated for each zone and compared to the predicted Broselow and Handtevy weights using measures of bias, precision, and accuracy. A sub-sample was examined that excluded cases with body mass index (BMI)≥95th percentile. Weights of children longer than each tape also were examined. Results A total of 3,018 cases from the NHANES database met criteria. Although both tapes underestimated children’s weight, the Broselow tape outperformed the Handtevy tape across most length ranges in measures of bias, precision, and accuracy of predicted weights relative to actual weights. Accuracy was higher in the Broselow tape for shorter children and in the Handtevy tape for taller children. Among the sub-sample with cases of BMI≥95th percentile removed, performance of the Handtevy tape improved, yet the Broselow tape still performed better. When assessing the weights of children who were longer than either tape, the actual mean weights did not approximate adult weights; although, those exceeding the Handtevy tape were closer. Conclusions For pediatric weight estimation, the Broselow tape performed better overall than the Handtevy tape and more closely approximated actual weight. LoweCG, CampwalaRT, ZivN, WangVJ.

The impact of stroke consequences on spousal relationships from the perspective of the person with stroke.

AIMS AND OBJECTIVES This paper aims to provide a subjective insight into the experience of stroke recovery within spousal relationships. The aftermath of stroke and its impact on the physical, emotional, psychological and social effects of spousal relationships are explored. BACKGROUND Many studies have examined observable functional recovery following stroke from the perspective of health care professionals. Longer-term effects of stroke such as changes in role and perception of self can alter significantly the dynamics of spousal relationships. Despite this, little attention has been given to the subjective impact of stroke on spousal relationships. DESIGN A qualitative study design was adopted. Individual, audio-taped interviews were carried out over three months. METHODS A convenience sample of 16 stroke survivors was recruited from the Stroke Nurse Specialist Register. All participants were over 18 years old and had been discharged from hospital following a diagnosis of stroke. Transcribed interviews were analysed using content data analysis to code and categorise emerging themes. RESULTS Poststroke, spousal relationships altered significantly in terms of sexuality, sexual desire and sexual functioning. Within their role of husband or wife, stroke survivors described a lack of control and dramatic changes in their perception of self. CONCLUSIONS Survivors of stroke experience profound, complex and multi-faceted difficulties in many areas of their spousal relationships, which are distressing to both them and their spouses. These have a significant impact on each individual's quality of life particularly in the longer term. RELEVANCE TO CLINICAL PRACTICE Health care professionals and service providers need to understand and recognise the subjective experience of stroke and the complex difficulties that stroke survivors experience within their spousal relationships. It would appear that current service provision does not adequately address the range of needs that the stroke survivors described in this study.
Growth and adult height in GH-treated children with nonacquired GH deficiency and idiopathic short stature: the influence of pituitary magnetic resonance imaging findings.

We analyzed the final height of 146 short children with either nonacquired GH deficiency or idiopathic short stature. Our purpose was 1) to assess growth according to the pituitary magnetic resonance imaging findings in the 63 GH-treated children with GH deficiency and 2) to compare the growth of the GH-deficient patients with normal magnetic resonance imaging (n = 48) to that of 32 treated and 51 untreated children with idiopathic short stature (GH peak to provocative tests >10 microg/liter). The mean GH dose was 0.44 IU/kg.wk (0.15 mg/kg.wk), given for a mean duration of 4.6 yr. Among the GH-deficient children, 15 had hypothalamic-pituitary abnormalities (stalk agenesis), all with total GH deficiency (GH peak <5 microg/liter). They were significantly shorter and younger at the time of diagnosis than those with normal magnetic resonance imaging, had better catch-up growth (+2.7 +/- 0.9 vs. +1.3 +/- 0.8 SD score; P < 0.01), and reached greater final height (-1.1 +/- 1.0 vs. -1.7 +/- 1.0 SD score; P < 0.05). Among patients with normal magnetic resonance imaging, there was no difference in catch-up growth and final height between partial and total GH deficiencies. GH-deficient subjects with normal magnetic resonance imaging and treated and untreated patients with idiopathic short stature had comparable auxological characteristics, age at evaluation, and target height. Although they had different catch-up growth (+1.3 +/- 0.8, +0.9 +/- 0.6, and +0.7 +/- 0.9 SD score, respectively; P < 0.01, by ANOVA), these patients reached a similar final height (-1.7 +/- 1.0, -2.1 +/- 0.8, and -2.1 +/- 1.0 SD score, respectively; P = 0.13). Pituitary magnetic resonance imaging findings show the heterogeneity within the group of nonacquired GH deficiency and help to predict the response to GH treatment in these patients. The similarities in growth between the GH-deficient children with normal magnetic resonance imaging and those with idiopathic short stature suggest that the short stature in the former subjects is at least partly due to factors other than GH deficiency.
