Image sequence stabilization by low-pass filtering of interframe motion

An image sequence stabilization system that removes translational jitter while preserving intentional camera pan is presented. The video sequence is processed to acquire global camera translations from frame to frame (global interframe motion vectors) by motion estimation. The resulting motion vectors are accumulated to construct an absolute frame position vs. frame number signal. This signal is low-pass filtered to remove high frequency components caused by jitter, and retain low frequency parts representing the intentional camera pan. Correction vectors for image frames are obtained by subtracting the absolute frame position from the low-pass filtered value, and stabilization is achieved by the corresponding translation of image frames.
Essential role for Sonic hedgehog during hair follicle morphogenesis.

The hair follicle is a source of epithelial stem cells and site of origin for several types of skin tumors. Although it is clear that follicles arise by way of a series of inductive tissue interactions, identification of the signaling molecules driving this process remains a major challenge in skin biology. In this study we report an obligatory role for the secreted morphogen Sonic hedgehog (Shh) during hair follicle development. Hair germs comprising epidermal placodes and associated dermal condensates were detected in both control and Shh -/- embryos, but progression through subsequent stages of follicle development was blocked in mutant skin. The expression of Gli1 and Ptc1 was reduced in Shh -/- dermal condensates and they failed to evolve into hair follicle papillae, suggesting that the adjacent mesenchyme is a critical target for placode-derived Shh. Despite the profound inhibition of hair follicle morphogenesis, late-stage follicle differentiation markers were detected in Shh -/- skin grafts, as well as cultured vibrissa explants treated with cyclopamine to block Shh signaling. Our findings reveal an essential role for Shh during hair follicle morphogenesis, where it is required for normal advancement beyond the hair germ stage of development.

Subadult dietary variation at Trino Vercellese, Italy, and its relationship to adult diet and mortality.

OBJECTIVES Early-life nutrition is a predisposing factor for later-life outcomes. This study tests the hypothesis that subadults from medieval Trino Vercellese, Italy, who lived to adulthood consumed isotopically different diets compared with subadults who died before reaching adulthood. We have previously used a life history approach, comparing dentine and bone of the same adult individuals ("subadults who lived"), to elucidate dietary variation across the life span. Here, we examine diets of "subadults who died" from the same population, estimated from subadult rib collagen, to explore whether dietary behaviors of subadults who lived differed from those of subadults who died. METHODS Forty-one subadults aged six months to 14.5 years were studied through stable carbon and nitrogen isotope analysis of collagen. RESULTS Individuals were weaned by age 4 years, with considerable variation in weaning ages overall. Post-weaning, diets of subadults who died comprised significantly less animal protein than diets of subadults who lived. Isotopic values of the two oldest individuals, 13.5 and 14.5 years, show the same status-based variation in diet as do adults from the population. CONCLUSIONS Our results suggest that incorporating animal protein in diet during growth and development supported medieval subadults' ability to survive to adulthood. Isotopic similarities between adults and older subadults suggest "adult" dietary behaviors were adopted in adolescence. Stable isotope evidence from subadults bridges a disparity between ontogenetic age categories and socioculturally meaningful age categories in the past, and sheds light on the underpinnings of health, mortality, growth, and disease in the bioarchaeological record.

Fruit and vegetable intake and cognitive function in the SU.VI.MAX 2 prospective study.

BACKGROUND Current hypotheses suggest that intake of fruit and vegetables (FVs) protects against age-related cognitive impairment. OBJECTIVE We examined the 13-y association between FV intake and cognitive performance in a sample of French adults. DESIGN A total of 2533 subjects aged 45-60 y at baseline, who were part of the Supplementation with Antioxidant Vitamins and Minerals 2 (SU.VI.MAX 2) cohort, were selected. FV intake was estimated at baseline in participants who had completed at least six 24-h dietary records. Cognitive performance was assessed 13 y after baseline and included an evaluation of verbal memory (RI-48 cued recall, semantic, and phonemic fluency tests) and executive function (trail-making and forward and backward digit span tests). Principal components analysis was performed to account for correlations in test scores. The relation between cognitive performance and quartiles of FV intake was assessed by multivariate linear regression analyses. RESULTS Intakes of FVs (P-trend = 0.02), fruit alone (P-trend = 0.04), vitamin C-rich FVs (P-trend = 0.03), vitamin C (P-trend = 0.005), and vitamin E (P-trend = 0.04) were positively associated with verbal memory scores. In contrast, intakes of FVs (P-trend = 0.006), vegetables alone (P-trend = 0.03), and β-carotene-rich FVs (P-trend = 0.02) were negatively associated with executive functioning scores. CONCLUSIONS FVs might have a differential effect on cognition according to groups of FVs and type of cognitive function. Further research using sensitive and reliable measures of various types of cognitive function is needed to clarify the effect of individual FV groups and nutrients. This trial is registered at clinicaltrials.gov as NCT00272428.

The Company States Keep: Bibliography

This book argues that investor risk in emerging markets hinges on the company a country keeps. When a country signs on to an economic agreement with states that are widely known to be stable, it looks less risky. Conversely, when a country joins a group with more unstable members, it looks more risky. Investors use the company a country keeps as a heuristic in evaluating that country's willingness to honor its sovereign debt obligations. This has important implications for the study of international cooperation as well as of sovereign risk and credibility at the domestic level.
Task Instruction: the largest Influence on Human Operator Motion Control Dynamics

The dynamics of the human operator while interacting with a haptic interface are often either neglected or at best modeled as a constant mass-spring-damper model. However, it is well known that humans are able to substantially modify their dynamic behaviour. The goal of this study is to show the extent to which humans can modify their endpoint dynamics while interacting with a haptic manipulator. In an experimental study, the endpoint dynamics of the ankle-foot complex were estimated as an admittance using closed-loop identification techniques. Subjects were perturbed with continuous torque perturbations and required to perform three tasks: to maintain a constant position (position task), to maintain a constant force (force task) and to relax. Results indicate that subjects substantially decrease their admittance during a position task compared to a force task (up to a factor of 40 at frequencies below 0.5 Hz.), indicating they could choose to resist the torque perturbations or not. It is concluded that modeling the human as a constant mass-spring-damper system can lead to substantial errors in the design of haptic systems

GENDER-BASED PAY GAPS

Methodology is often a point of contention in gender-based salary studies. Although this debate seems at first to be merely about technical issues, it also has an important conceptual dimension. We argue that there are two competing implicit conceptions of discrimination, one institutional and the other individual, that underlie many such debates. We first contrast the preferred methodologies advanced by each side, the policy capturing approach and the flagging approach, and explore the theoretical meaning of their statistical models. We then describe a practical application of both methodological approaches in one specific salary inequity study. In conclusion, we reflect on the implications of such practical statistical choices, discuss how such models can be combined, and make suggestions for sociologists who act as statistical experts or work with them in gender-based salary inequity studies on their own campuses.
Brillouin Sensing Cable: Design and Experimental Validation

We report on the design and experimental validation of a distributed Brillouin-based optical fiber sensor embedded into concrete structures for temperature and strain measurement. A composite-made wave-like coating designed by finite-element analysis ensures the sensor is transferring optimally temperature and strain fields from the concrete to the optical fiber, where Brillouin scattering takes place. During all experiments, sensors have been interrogated with a commercially available Brillouin optical time-domain reflectometer unit. First, temperature sensitivity of the Brillouin frequency shift were evaluated in PANDA and SMF28 optical fibers, before wrapping them into the specific sheath for embedment into a 3 m-long reinforced concrete beam. Temperature measurements during concrete beam casting agreed with reference measurements, and showed the significant sensor coating influence. A month later, strain measurements performed during a four-point bending experiment showed promising results: linearity and reliability of measurements were demonstrated, under tensile as well as compressive loadings.
Azimuth fractional transformation of the fractional chirp scaling algorithm (FrCSA)

The fractional chirp scaling algorithm (FrCSA) is based on the use of the fractional Fourier transform (FrFT) within the chirp scaling algorithm (CSA). In this paper, a closed-form expression for the azimuth FrFT of the FrCSA is mathematically derived and analyzed from the high-resolution synthetic aperture radar imaging point of view. The azimuth-FrFT expression of the FrCSA is compared to that of the classical fast Fourier transform (FFT)-based CSA. As the FFT is a special case of the generalized FrFT, the derived expression is found to be in total agreement with that of the FFT-based CSA when the transformation order is equal to unity; that is the angle of rotation is equal to pi/2
Diagnosis of porcelain and glass insulators conditions using phase angle index based on experimental tests

In this paper, an improved method to diagnose the critical conditions in the porcelain and glass insulators has been proposed through investigating leakage current (LC) and applied voltage signals. Hence, Fast Fourier Transform (FFT) analysis has been used to calculate the phase angle values of the applied voltage and LC signals. Analyzing phase angle difference of LC and applied voltage waveforms demonstrate a strong correlation of the phase difference between the applied voltage and LC waveforms with the insulators conditions. So, the phase difference cosine (P.D%) has been offered as a diagnostic index of porcelain and glass insulators conditions. In this case, when the P.D% value is lower than 30%, the insulators are in clean and normal conditions. On the other hand, if the P.D% is more than 30%, the insulators are in extreme conditions. Moreover, by increasing %P.D value more than 85%, the probability of the flashover occurrence in porcelain and glass insulators will be very high. The obtained experimental results validate the veracity of considering P.D% as a criterion for prediction of flashover in porcelain and glass insulators.
Management practices among small holders of sheep, goats and pigs in the derived savanna zone in Oyo State, Nigeria

A study was conducted to assess the systems of management adopted by small farm holders of sheep, goats and pigs in Oyo State, Nigeria. Data were collected from a total of 25 farms spread over the villages and towns using structured questionnaires. The study revealed that most farmers keep a combination of sheep and goats. Ninety-two percent of the respondents were private owners, while 12% of the respondents indicated a community or group ownership of the farms. Most of the farm holders were males (84%) having 6 to 10 years experience in livestock farming. Personal savings constituted the major source of capital for the enterprise. Sixty-four percent of the farms reared their animals semi-intensively compared with 32% for intensive and 4% for extensive. Eighty percent of the farmers fed their animals twice daily, mainly on pasture along with other feed supplements such as cassava. The animals were infested with various diseases and were treated only when infected. Prevention or control of diseases was done through vaccination and good hygiene and feeding. Most of the livestock were disposed or sold off at adult age. Keywords: Management, small farm holders, sheep, goats, pigs
Prediction of Pancreatic Neuroendocrine Tumor Grade Based on CT Features and Texture Analysis.

OBJECTIVE The purposes of this study were to assess whether CT texture analysis and CT features are predictive of pancreatic neuroendocrine tumor (PNET) grade based on the World Health Organization (WHO) classification and to identify features related to disease progression after surgery. MATERIALS AND METHODS Preoperative contrast-enhanced CT images of 101 patients with PNETs were assessed. The images were evaluated for tumor location, tumor size, tumor pattern, predominantly solid or cystic composition, presence of calcification, presence of heterogeneous enhancement on contrast-enhanced images, presence of pancreatic duct dilatation, presence of pancreatic atrophy, presence of vascular involvement by the tumor, and presence of lymphadenopathy. Texture features were also extracted from CT images. Surgically verified tumors were graded according to the WHO classification, and patients underwent CT or MRI follow-up after surgical resection. Data were analyzed with chi-square tests, kappa statistics, logistic regression analysis, and Kaplan-Meier curves. RESULTS The CT features predictive of a more aggressive tumor (grades 2 and 3) were size larger than 2.0 cm (odds ratio [OR], 3.3; p = 0.014), presence of vascular involvement (OR, 25.2; p = 0.003), presence of pancreatic ductal dilatation (OR, 6.0; p = 0.002), and presence of lymphadenopathy (OR, 6.8; p = 0.002). The texture parameter entropy (OR, 3.7; p = 0.008) was also predictive of more aggressive tumors. Differences in progression-free survival distribution were found for grade 1 versus grades 2 and 3 tumors (χ2 [df, 1] = 21.6; p < 0.001); for PNETs with vascular involvement (χ2 [df, 1] = 20.8; p < 0.001); and for tumors with entropy (spatial scale filter 2) values greater than 4.65 (χ2 (df, 1) = 4.4; p = 0.037). CONCLUSION CT texture analysis and CT features are predictive of PNET aggressiveness and can be used to identify patients at risk of early disease progression after surgical resection.
ANALISIS PENGARUH KETIDAKPUASAN KONSUMEN, IKLAN PESAING DAN PERILAKU MENCARI VARIASI TERHADAP PERILAKU PERPINDAHAN MEREK PADA KONSUMEN SHAMPO SUNSILK

This study is grounded by the decreasing of Sunsilk’s market share in 3 (three) years a row which indicates the occurrence phenomenon of consumer switching from Sunsilk to other shampoo. This phenomenon is usually called brand switching. Therefore, the problem in this study is “ what are the factors that influence consumers switching from shampoo to another shampoo brand ” . This study examined three independent variables; there are consumer dissatisfaction, competitor’s advertising and variety seeking behavior toward brand switching behavior. The purpose of this study is to find the influence of the independent variables toward brand switching behavior. This study uses a questionnaire method with purposive sampling technique to 100 people who had used Sunsilk before and have switched to another shampoo brand. Then, the writer uses the qualitative and quantitative analysis to analyze the data. The quantitative analysis includes the test of validity, reliability, classic assumption, double regression analysis, test hypotheses and test the feasibility of the model through ANOVAs test and value of adjusted R square. The results of this study indicate that the independent variables used in this study, that consumer dissatisfaction, competitor’s advertising and variety-seeking behavior is feasible to test the dependent variable through the ANOVAs test. The t test results showed that all independent variables are tested has a positive and significant effect on the brand switching behavior. The Adjusted R Square is 0,267 which indicates that 26,7% variation of brand switching behavior can be explained by the two independent variables and the remaining 73,3% is explained by other factors beyond this study.
A Two-Dimensional Model for the Study of Interpersonal Attraction

We describe a model for understanding interpersonal attraction in which attraction can be understood as a product of the initial evaluations we make about others. The model posits that targets are evaluated on two basic dimensions, capacity and willingness, such that affective and behavioral attraction result from evaluations of (a) a target’s capacity to facilitate the perceiver’s goals/needs and (b) a target’s potential willingness to facilitate those goals/needs. The plausibility of the two-dimensional model of attraction is evaluated vis-à-vis the extant literature on various attraction phenomena including the reciprocity of liking effect, pratfall effect, matching hypothesis, arousal effects, and similarity effect. We conclude that considerable evidence across a wide range of phenomena supports the idea that interpersonal attraction is principally determined by inferences about the target’s capacity and willingness.
Test/retest repeatability of effect contralateral acoustic stimulation on the magnitudes of distortion product ototacoustic emissions

Contralateral inhibition of distortion product otoacoustic emissions (DPOAE) has become an important tool to assess the functioning of the medial olivocochlear efferents in humans. However, before this measurement can be applied clinically, the test/retest repeatability needs to be established. Therefore, the current study aimed at evaluating intra‐ and intersession test/retest repeatability of contralateral inhibition of DPOAE at 2f1–f2.
The long run impact of rights issues on share price performance and operating performance

Rights issues continue to be a well-researched topic within the field of corporate finance. The focus of this study was to consider the long-run impact of rights issue on company performance both in terms of share price performance and operating performance. The long-run perspective taken in this study adds to the literature, which usually looks at the immediate share price reaction to a rights issue announcement. The study also looked at whether the intended use of capital stated in the SENS announcement had any post-issue effect on the share price. The study found significantly negative cumulative average abnormal returns within the first year after the rights issue. This study confirms the expected negative share price reaction to a rights issue announcement. The study also found evidence that companies that use the proceeds to repay debt, invest or for general purposes had a negative share price reaction to a rights issue announcement. Companies that were vague about the intended purpose of the rights issue had the largest post-issue underperformance. The study did not find any statistically significant evidence that the rights issue announcement had any effect on the operating performance. These findings suggest that rights issues have more impact on a company’s share price, and no clear impact on the operating performance of the issuing company.
