Original analytical model of the hydrodynamic loads applied on the half bridge of a circular settling tank
Venue: Advanced Topics in Optoelectronics, Microelectronics, and Nanotechnologies

The paper presents an original analytical model of the hydrodynamic loads applied on the half bridge of a circular settling tank. The calculus domain is defined using analytical geometry and the calculus of the local dynamic pressure is based on the radius from the center of the settling tank to the current area, i.e. the relative velocity of the fluid and the depth where the current area is located, i.e. the density of the fluid. Calculus of the local drag forces uses the discrete frontal cross sectional areas of the submerged structure in contact with the fluid. In the last stage is performed the reduction of the local drag forces in the appropriate points belonging to the main beam. This class of loads is producing the flexure of the main beam in a horizontal plane and additional twisting moments along this structure. Taking into account the hydrodynamic loads, the results of the theoretical models, i.e. the analytical model and the finite element model, may have an increased accuracy.
Content Based High Resolution Remote Sensing Image Retrieval via Unsupervised Feature Learning and Collaborative Affinity Metric Fusion
Venue: Remote. Sens.

With the urgent demand for automatic management of large numbers of high resolution remote sensing images, content based high resolution remote sensing image retrieval (CB HRRS IR) has attracted much research interest. Accordingly, this paper proposes a novel high resolution remote sensing image retrieval approach via multiple feature representation and collaborative affinity metric fusion (IRMFRCAMF) In IRMFRCAMF, we design four unsupervised convolutional neural networks with different layers to generate four types of unsupervised features from the fine level to the coarse level. In addition to these four types of unsupervised features, we also implement four traditional feature descriptors, including local binary pattern (LBP) gray level co occurrence (GLCM) maximal response 8 (MR8) and scale invariant feature transform (SIFT) In order to fully incorporate the complementary information among multiple features of one image and the mutual information across auxiliary images in the image dataset, this paper advocates collaborative affinity metric fusion to measure the similarity between images. The performance evaluation of high resolution remote sensing image retrieval is implemented on two public datasets, the UC Merced (UCM) dataset and the Wuhan University (WH) dataset. Large numbers of experiments show that our proposed IRMFRCAMF can significantly outperform the state of the art approaches.
Deep Multi task Attribute driven Ranking for Fine grained Sketch based Image Retrieval
Venue: BMVC

Fine grained sketch based image retrieval (SBIR) aims to go beyond conventional SBIR to perform instance level cross domain retrieval: finding the specific photo that matches an input sketch. Existing methods focus on designing/learning good features for cross domain matching and/or learning cross domain matching functions. However, they neglect the semantic aspect of retrieval, i.e. what meaningful object properties does a user try encode in her/his sketch? We propose a fine grained SBIR model that exploits semantic attributes and deep feature learning in a complementary way. Specifically, we perform multi task deep learning with three objectives, including: retrieval by fine grained ranking on a learned representation, attribute prediction, and attribute level ranking. Simultaneously predicting semantic attributes and using such predictions in the ranking procedure help retrieval results to be more semantically relevant. Importantly, the introduction of semantic attribute learning in the model allows for the elimination of the otherwise prohibitive cost of human annotations required for training a fine grained deep ranking model. Experimental results demonstrate that our method outperforms the state of the art on challenging fine grained SBIR benchmarks while requiring less annotation.
Image Processing With Color Compensation Using LCD Display for Color Vision Deficiency
Venue: Journal of Display Technology

Color vision deficiency (CVD) is an inability or decreased ability to see color or perceive color difference under normal lighting conditions. In this paper, we propose the CVD compensation image processing method including backlight control algorithm for LCD display in order to give people real world color experience through display devices. We used a physiologically based anomalous trichromacy model which defines the cause of color vision deficiency as a shift of spectral response of LMS cones. In order to compensate for the shift in spectral response of L, M, and S cones, we used an inversesimulation matrix model. Proposed algorithm for compensation of CVD was simulated and verified by image processing tools.
A geometric perspective on p adic properties of mock modular forms

AbstractBringmann et al. ( 2012) showed how to 'regularize' mock modular forms by a certain linear combination of the Eichler integral of their shadows in order to obtain p adic modular forms in the sense of Serre. In this paper, we give a new proof of a refined form of their results (for good primes p) by employing the geometric theory of harmonic Maass forms developed by Candelori ( 2014) and the theory of overconvergent modular forms due to Katz and Coleman. In particular, our main results imply that the p adic modular forms in Bringmann et al. (2012) are overconvergent.
Genetic, hormonal and metabolic aspects of PCOS: an update
Venue: Reproductive Biology and Endocrinology

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5 10 of women of reproductive age. It generally manifests with oligo/anovulatory cycles, hirsutism and polycystic ovaries, together with a considerable prevalence of insulin resistance. Although the aetiology of the syndrome is not completely understood yet, PCOS is considered a multifactorial disorder with various genetic, endocrine and environmental abnormalities. Moreover, PCOS patients have a higher risk of metabolic and cardiovascular diseases and their related morbidity, if compared to the general population.
Adolescents' interest in trying flavoured e cigarettes
Venue: Tobacco Control

More US adolescents use e cigarettes than smoke cigarettes. Research suggests flavoured e cigarettes appeal to youth, but little is known about perceptions of and reasons for attraction to specific flavours.  A national sample of adolescents (n=1125) ages 13 17 participated in a phone survey from November 2014 to June 2015. We randomly assigned adolescents to respond to survey items about 1 of 5 e cigarette flavours (tobacco, alcohol, menthol, candy or fruit) and used regression analysis to examine the impact of flavour on interest in trying e cigarettes and harm beliefs.  Adolescents were more likely to report interest in trying an e cigarette offered by a friend if it were flavoured like menthol (OR=4.00, 95% CI 1.46 to 10.97) candy (OR=4.53, 95% CI 1.67 to 12.31) or fruit (OR=6.49, 95% CI 2.48 to 17.01) compared with tobacco. Adolescents believed that fruit flavoured e cigarettes were less harmful to health than tobacco flavoured e cigarettes (p<0.05) Perceived harm mediated the relationship between some flavours and interest in trying e cigarettes. A minority of adolescents believed that e cigarettes did not have nicotine (14.6% or did not know whether they had nicotine (3.6% these beliefs did not vary by flavour.  Candy flavoured, fruit flavoured and menthol flavoured e cigarettes appeal to adolescents more than tobacco flavoured or alcohol flavoured e cigarettes. This appeal is only partially explained by beliefs about reduced harm. Given adolescents' interest in trying e cigarettes with certain flavours, policymakers should consider restricting advertisements promoting flavoured products in media that reach large numbers of young people. Future research should examine other reasons for the appeal of individual flavours, such as novelty and perceived luxury.
Impact of advertisements promoting candy like flavoured e cigarettes on appeal of tobacco smoking among children: an experimental study
Venue: Tobacco Control

There are concerns that the marketing of e cigarettes may increase the appeal of tobacco smoking in children. We examined this concern by assessing the impact on appeal of tobacco smoking after exposure to advertisements for e cigarettes with and without candy like flavours, such as, bubble gum and milk chocolate.  We assigned 598 English school children (aged 11 16 years) to 1 of 3 different conditions corresponding to the adverts to which they were exposed: adverts for flavoured e cigarettes, adverts for non flavoured e cigarettes or a control condition in which no adverts were shown. The primary endpoint was appeal of tobacco smoking. Secondary endpoints were: appeal of using e cigarettes, susceptibility to tobacco smoking, perceived harm of tobacco, appeal of e cigarette adverts and interest in buying and trying e cigarettes.  Tobacco smokers and e cigarette users were excluded from analyses (final sample=471) Exposure to either set of adverts did not increase the appeal of tobacco smoking, the appeal of using e cigarettes, or susceptibility to tobacco smoking. Also, it did not reduce the perceived harm of tobacco smoking, which was high. Flavoured e cigarette adverts were, however, more appealing than adverts for non flavoured e cigarettes and elicited greater interest in buying and trying e cigarettes.  Exposure to adverts for e cigarettes does not seem to increase the appeal of tobacco smoking in children. Flavoured, compared with non flavoured, e cigarette adverts did, however, elicit greater appeal and interest in buying and trying e cigarettes. Further studies extending the current research are needed to elucidate the impact of flavoured and non flavoured e cigarette adverts.
Using Multi Stage Features in Fast R CNN for Pedestrian Detection
Venue: DSAI

Pedestrian detection and tracking remains popular issue in computer vision, with many applications in robotics, surveillance, security and telecare systems, especially when connected with Smart Cities and Smart Destinations. As a particular case of object detection, pedestrian detection in general is a difficult task due to a large variability of features due to different scales, views and occlusion. Typically, smaller and occluded pedestrians are hard to detect due to fewer discriminative features if compared to large size, visible pedestrians. In order to overcome this, we use convolutional features from different stages in a deep Convolutional Neural Network (CNN) with the idea of combining more global features with finer details. In this paper we present an object detection framework based on multi stage convolutional features for pedestrian detection. This framework extends the Fast R CNN framework for the combination of several convolutional features from different stages of the used CNN to improve the network's detection accuracy. The Caltech Pedestrian dataset was used to train and evaluate the proposed method.
A Binarization Scheme for Face Recognition Based on Multi Scale Block Local Binary Patterns
Venue: 2016 International Conference of the Biometrics Special Interest Group (BIOSIG)

Local binary patterns (LBP) represent a well established technique for reliable facial recognition. Multi scale block (MB) LBP, which process average pixel values of block sub regions instead of single pixels, have been proposed in order to achieve more robust feature vectors, which consist of histograms of (MB) LBP values. In this work, we present a simple, yet effective, method to binarize histograms obtained from a MB LBP face recognition system. The proposed method extracts compact binary feature vectors which allow for a rapid comparison and which are required for privacy enhanced biometric processing, when biometric template protection is enabled. On the publicly available FERET and Extended Yale B dataset, the presented scheme reveals only a negligible drop in biometric performance compared to the original MB LBP system, while a substantial speed up is achieved in the comparison stage.
Japan, Korea, and China: Styles of ODA in East Asia

East Asian donors have come to play an increasingly important role in the international foreign aid regime over the past couple of decades. Japan, Korea, and China are the leading actors from the region and have provided many tens of billions of dollars to countries in Asia itself, as well as sub Saharan Africa (SSA) and Latin America.1 In addition, they have taken an active part in international discussions of foreign aid and have suggested themselves as models of development that recipient nations might follow.
The Fundamental Group of $SO(n) Via Quotients of Braid Groups

We describe an algebraic proof of the well known topological fact that \pi_1(SO(n) \cong Z/2Z$ The fundamental group of $SO(n) appears in our approach as the center of a certain finite group defined by generators and relations. The latter is a factor group of the braid group $B_n$ obtained by imposing one additional relation and turns out to be a nontrivial central extension by $Z/2Z$ of the corresponding group of rotational symmetries of the hyperoctahedron in dimension $n$

Prevalence of Traumatic Dental Injuries to Anterior Teeth of 12 Year Old School Children in Kashmir, India
Venue: Archives of trauma research

Traumatic dental injuries to anterior teeth are a significant public health problem, not only because their prevalence is relatively high, but also because they have considerable impact on children's daily lives. Traumatic dental injuries (TDIs) cause physical and psychological discomfort, pain and other negative impacts, such as tendency to avoid laughing or smiling, which can affect social relationships.  This study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12 year old school children in Kashmir, India.  A cross sectional study was conducted in private and government schools of India among 1600 schoolchildren aged 12 years. In addition to recording of the type of trauma (using Ellis and Davey classification of fractures, 1970) over jet, Angle's molar relation and lip competence were also recorded. The socioeconomic status and academic performance of the study subjects were registered. The data obtained were compiled systematically and then statistically analyzed. The statistical significance for the association between the traumatic injury and the variables was analyzed using the chi square test. Logistic regression was used to identify potential risk predictors of TDIs.  The overall prevalence of TDI to anterior teeth was found to be 9.3% The TDI to anterior teeth in male was more than female, but the difference was statistically nonsignificant (P 0.01) Falls and sports were the most common causes of trauma in the present study. The highest potential risk factor for the occurrence of trauma was over jet. Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model.  It was concluded that the prevalence of traumatic dental injuries was 9.3% Traumatic dental injuries among children exhibit complex interaction between the victims' oral conditions and their behavior. Therefore, prevention should consider a number of characteristics such as oral predisposing factors, environmental determinants and human behavior. It is recommended that specific and proper public places for leisure and sports activities, with impact absorbing surfaces around the items on which children are most likely to fall, should be provided.
Primary Care Physicians' Adherence to Guidelines and Their Likelihood to Prescribe the Human Papillomavirus Vaccine for 11 and 12 Year Old Girls.
Venue: Women's health issues official publication of the Jacobs Institute of Women's Health

Inadequate physician adherence to guidelines has received scant attention as a possible cause of suboptimal human papillomavirus (HPV) vaccination rates. We assessed the extent to which primary care physicians (PCPs) adhere to clinical guidelines and their reported intentions to prescribe HPV vaccine to females in the targeted age group, and how this is influenced by perceptions of guideline clarity and other factors.  We surveyed 301 PCPs to explore their sociodemographic and practice related characteristics, beliefs, professional norms, and perceived barriers to administer HPV vaccine. Logistic regression predicted the likelihood to prescribe HPV vaccine to 11 and 12 year old girls on an array of variables hypothesized to influence physicians' recommendations.  Only 67% of PCPs reported being likely to prescribe HPV vaccine to 11 and 12 year old patients. PCPs were more likely to prescribe vaccine to 11 and 12 year old girls if they believed HPV vaccine guidelines were clear (odds ratio [OR] 1.85; 95% CI, 1.03 3.35) agreed with a mandate requirement (OR, 2.39; 95% CI, 1.01 5.61) felt comfortable discussing HPV vaccination with early adolescent girls (OR, 5.10; 95% CI, 2.75 9.45) and had at least 25% of their patients using public assistance to pay for their clinic visits (OR, 3.82; 95% CI, 1.91 7.34) Practice specialty (family physicians or pediatricians) and region were not significant predictors.  PCPs exhibit moderate levels of adherence to professional guidelines regarding HPV vaccination. Potential public health benefits will not be realized without stronger efforts to improve the rates at which PCPs administer the vaccine, particularly to 11 and 12 year olds for whom it is preferentially recommended.
Validity of an Athletic Skills Track among 6 to 12 year old children
Venue: Journal of sports sciences

The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6 to 12 year old children in a physical education setting. Four hundred sixty three Dutch children (211 girls, 252 boys) completed three tests: the Korperkoordinationstest fur Kinder (KTK) and two Athletic Skills Tracks (AST 1, AST 2) The validity of AST 1 and AST 2 was examined by correlating the time (s) needed to complete the tracks and the KTK Motor Quotient (MQ) Overall, there was a low correlation between AST 1 and the KTK MQ (r 0.474 (P 0.01) and a moderate correlation between AST 2 and the KTK MQ (r 0.502 (P 0.01) When split up by age group the associations were much higher and ranged between r 0.469 and r 0.767) with the exception of the low correlation coefficient of the AST 2 in 7 year olds. The results indicate that fundamental movement skills of 6 to 12 year old children can be assessed with a quick, convenient and low cost motor competence test in a physical education setting, i.e. an Athletic Skills Track. Future studies should further assess the reliability, discriminative ability and validity of age specific versions of the AST.
Development of cycling skills in 7 to 12 year old children
Venue: Traffic injury prevention

Cycling is a complex skill consisting of motor skills such as pedalling, braking, and steering. Because the ability to perform cycling skills is based on the age related development of the child, experience and age related reference values are of interest in light of customized testing and training.  One hundred thirty eight children from the second (7 8 years) fourth (9 10 years) and sixth (11 12 years) grades performed a practical bicycle test consisting of 13 test items with specific points of interest. Moreover, age at onset of cycling, cycling to and from school, independent mobility, and minutes cycling per week were estimated using a parental questionnaire.  It is found that cycling skills are strongly related to age with 11 to 12 year old children outperforming 7 to 8 year old children for 11 test items and 9 to 10 year old children for 8 test items.  Next to age, age at onset of cycling also contributed to cycling skills. Therefore, our results suggest that cycling skills are associated with physical and mental maturation. Subsequently, age related reference values are provided to customize testing and training.
