TRIT: A ROBUST TRACKER BASED ON

In this paper, a target tracking algorithm, TriT(Triplet Network Based Tracker), based on Triplet network is proposed to solve the problem of visual target tracking in complex scenes. Compared with Siamese-fc algorithm, which adopts a two-way feature extraction network, TriT uses three parallel convolutional neural networks to extract the features of the target in the first frame, the target in the previous frame and the search regions of the current frame, and then obtains the high-level semantic information of the three areas. Then, the features of the target in the first frame and the target in the previous frame are respectively convolved with the features of the current search region to obtain the similarity between each position in the search area and the target in the first frame and the target in the previous frame, so as to generate two similarity score maps. Then, interpolate and enlarge the two low-resolution score maps, and use the APCE value of the score maps as the medium to fuse the two score maps, according to which the position of the tracking target in the current frame can be located. Experiments in this paper have confirmed that, compared with some other real-time target tracking algorithms such as Siamese-fc, TriT has great advantages in tracking robustness and can effectively execute tracking tasks in complex scenes, such as illumination change, occlusion and interference of similar targets. Experimental results also show that the proposed algorithm has good real-time performance.

The impact of socio-economic deprivation on incidence, treatment and mortality from prostate cancer in England, 1990–2010

Objective: To explore any association between socio-economic deprivation and prostate cancer diagnosis and/or treatment. Patients and methods: Data was extracted as follows: We gained the incident cases and staging from the National Cancer Data Repository, survival from the Cancer Information System, mortality from the Office for National Statistics, treatment data from Hospital Episode Statistics and National Clinical Analysis and Specialised Applications Team. Our analysis regarding socio-economic deprivation was controlled for age distribution. Results: We recorded 518,453 diagnoses of prostate cancer; 174,579 prostate cancer deaths; 33,889 prostatectomies and 21,351 radiotherapy treatments. Incidence is increasing in all groups, but the highest is amongst the least deprived. Mortality is decreasing, with survival consistently better in the least deprived. Prostatectomies are more frequent in the least deprived; however, this gap is narrowing. Conclusions: Prostate cancer incidence, survival and treatment are associated with socio-economic deprivation. Prostatectomy rates show a decrease in the gap of inequality. Multiple potential confounding factors, such as rates of prostate specific antigen (PSA) testing and access to health care are associated with socio-economic deprivation. The unifying influences of Improving Outcomes Guidance and the National Treatment Guidelines are intended to counteract the above inequalities. Particularly in prostate cancer, where long-term gain depends on multiple factors, individualised treatment decisions are paramount.
Students’ Benefit Rate from Morning Report Sessions and Its Related Factors in Tehran University of Medical Sciences

Introduction: Morning report along with clinical rounds and ambulatory teaching are three common, useful and valuable methods (Gold Standards) in clinical education. This program has some characteristics and standards that, when properly applied, will play an effective role in students’ clinical learning. The main aim of this study is to determine the characteristics of morning report sessions in internal medicine wards affiliated to Tehran University of Medical Sciences, and also to assess students’ view points on the benefit and satisfaction from the content of these programs and the related factors. Methods: In this crosssectional study, the structural characteristics of morning report sessions and the students’ rate of benefit from their content were investigated in year 2010. A sample 300 internship and clerkship medical students were asked to fill out a researchermade questionnaire. The validity and reliability were confirmed by experts and the calculation of Cronbach’s alpha respectively. Results: The structural characteristics of the sessions were as follows: The average starting time of the sessions was at 8 a.m., the average duration of sessions was one hour, the average number of meetings was 5 times a week, the patient presenter in most cases was an intern, the cases presented were complicated and difficult ones, the average number of cases presented in each session was three, the average time for presenting each case was 20 minutes. Air conditioning, temperature, lighting, and sound quality were favorable. Faculty members usually sat in the front row and with their back to the audience. The main audience at the sessions was not defined and usually the experts of other fields such as pharmacists, nutritionists, pathologists or radiologists were absent. Total benefit rate according to the students was: 55 people (18.3%) high, 152 people (50.7%) moderate and 93 people (31%) low. There was a significant correlation between their benefit rate and most of the structural parameters of morning report sessions (P<0/005). Conclusion: Despite the structural conformity of the morning report sessions in internal medicine wards of Tehran University of Medical Sciences with those in most similar studies, some more efforts should be spent on promoting the students’ satisfaction.
Femmes à risques : évolution de l'oncogénétique en pratique quotidienne : Oncogénétique et questions éthiques

Une femme dont la mère ou la sœur a été atteinte de cancer du sein a un risque de cancer du sein multiplié par deux par rapport à celui de la population générale [1]. C’était le plus fort facteur de risque de cancer du sein repéré jusqu’à l’identification du gène BRCA1 en 1994 [2]. Le fait d’être porteur d’une mutation BRCA1 multiplie par dix le risque de cancer du sein. Cette découverte a constitué une avancée majeure dans la compréhension des formes familiales de cancer du sein et dans la prise en charge des femmes à risque. Le risque de cancer du sein des femmes ayant une histoire familiale réunissant plusieurs cas de cancers du sein avant l’âge de 50 ans chez des apparentées de premier degré était de l’ordre de 40 % avant l’ère des tests BRCA1/2. Cette valeur de 40 % était un moyen terme et une valeur virtuelle entre le risque de la population générale pour une femme si elle n’était pas prédisposée, et un risque majeur, de l’ordre de 80 %, si elle était prédisposée. Aujourd’hui, les tests génétiques permettent de passer à l’une ou l’autre de ces valeurs, et par là de rassurer les femmes non prédisposées et de mettre en œuvre une prise en charge spécifique des femmes prédisposées. De plus, ces tests permettent de connaître le risque de transmission à la descendance de la prédisposition : pas de risque pour un parent non porteur ou risque de 50 % pour un parent porteur. Pour la plupart des médecins qui conduisent ces tests génétiques, pour ceux qui prennent en charge les femmes à risque dans des structures spécialisées, ces tests génétiques apparaissent comme un progrès. En effet, différentes études, prenant en compte la diminution des risques tumoraux et la précocité du diagnostic avec le suivi d’un certain
MELAS Syndrome: An Uncommon Mitochondrial Inheritance

Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke (MELAS) syndrome is a progressive neurodegenerative disorder caused by mutations in the genes in the mitochondrial DNA. In most cases, the signs and symptoms of this disorder appear in childhood following a period of normal development. A 2 year old female child with global developmental delay presented with trauma to the paediatric OPD. On examination patient showed signs of microcephaly, hypotonia, reduced reflexes and abnormal vision. The child was hospitalized to evaluate reduced reflexes. Audiology evaluation reported affected receptive and expressive language. Low hemoglobin, elevated lactate: pyruvate ratio, reduced bicarbonate levels were found. Arterial blood gases analysis revealed metabolic acidosis.MRI of the brain showed acute infarction in basal ganglia and internal capsule. Based on the clinical and laboratory evaluation, patient was diagnosed as MELAS syndrome. Along with symptomatic treatment, Biotin and Coenzyme Q were supplemented to which patient responded progressively, thereby substantiating the diagnosis.
Deformability measurements on individual sickle cells using a new system with pO2 and temperature control

Although the rheologic behavior of sickle erythrocytes (SS cells) is highly dependent on oxygen tension (pO2) and temperature, very little data exist regarding the effects of deoxygenation and reoxygenation on the rheology of “individual” SS cells at body temperature. We have devised and assessed a new experiment system, in which micropipette aspiration can be performed on individual cells in a constant- temperature chamber that has ports for changing media with different pO2 (effected in 30 to 120 seconds) and sensing probes for monitoring pO2 and temperature. This system enabled us to simultaneously alter and monitor pO2 at 37 +/- 0.5 degrees C, and to monitor and study a single cell under microscopic observation. The static rigidity (E) and dynamic rigidity (eta) of individual SS cells were determined by repeated aspirations of the same cell under various pO2. With stepwise reductions in pO2, E and eta showed no significant changes before sickling, but once sickled, their values markedly increased by 10(2)- to 10(3)-fold concomitantly with morphologic alteration of the cell. Thus, the deformability of a single SS cell behaves in an “all or none” manner at a critical pO2, and earlier studies on the effect of deoxygenation on the rheology of SS cell suspensions probably reflect the overall behavior of SS cells with widely distributed critical pO2.
Fluidez verbal semántica de animales en el deterioro cognitivo leve de tipo amnésico

Introduccion y objetivo. El analisis cuantitativo y cualitativo de la tarea de fluidez verbal semantica ha permitido observar que las personas con demencia producen menos palabras y en grupos mas pequenos que las personas sin demencia. Sin embargo, en personas con deterioro cognitivo leve de tipo amnesico (DCLa) la investigacion ha mostrado resultados contradictorios respecto a la cantidad y el numero de los agrupamientos semanticos que se realizan. El objetivo de este estudio consistio en aportar nuevos datos para intentar solventar dicha controversia. Sujetos y metodos. Participaron en el estudio 22 personas mayores con diagnostico de DCLa (8 varones y 14 mujeres) y 43 adultos mayores (7 varones y 36 mujeres) con funcionamiento cognitivo normal que sirvieron de grupo control. Todos fueron evaluados en el Centro de Prevencion del Deterioro Cognitivo del Ayuntamiento de Madrid, tras completar la prueba de fluidez verbal de animales ademas de otras pruebas neuropsicologicas. Resultados. Como se esperaba, la produccion de animales fue menor en el grupo DCLa que en el grupo control, pero no se observaron diferencias ni en el tamano medio de las agrupaciones semanticas ni en el numero de cambios entre dichas agrupaciones. Conclusiones. Los resultados son coherentes con investigaciones previas que sugieren que en el DCLa no solo concurren deficits en la memoria episodica y la memoria operativa, sino tambien en la memoria semantica. Sin embargo, los datos no aclaran el papel de los procesos ejecutivos estrategicos, como parece suceder en la enfermedad de Alzheimer.
Complete theory of Ramsey interferometry with squeezing echos

We consider a large class of Ramsey interferometry protocols which are enhanced by squeezing and un-squeezing operations before and after a phase signal is imprinted on the collective spin of $N$ particles. We report an analytical optimization for any given particle number and strengths of (un-)squeezing, including experimentally relevant decoherence processes. This provides a complete characterization of squeezing echo protocols, recovering a number of known quantum metrological protocols as local sensitivity maxima, thereby proving their optimality. We discover a single new protocol. Its sensitivity enhancement relies on a double inversion of squeezing. In the general class of echo protocols, the newly found over-un-twisting protocol is singled out due to its Heisenberg scaling even at strong collective dephasing.
Quark condensate seesaw mechanism for neutrino mass

We study a mechanism of generation of Majorana neutrino mass due to spontaneous breaking of chiral symmetry (SBChS) accompanied by the formation of a quark condensate. The effect of the condensate is transmitted to the neutrino sector via Lepton-Number Violating (LNV) lepton-quark dimension-$7$ operators known in the literature as an origin of the neutrino-mass-independent mechanism of neutrinoless double-beta ($0 \nu \beta \beta$) decay. The smallness of neutrino masses is due to a large ratio between the LNV scale and the scale of the SBChS. This is a new realization of the seesaw mechanism, which we dub the Quark Condensate SeeSaw (QCSS). We show that its dominance requires a softly-broken symmetry suppressing the Weinberg operator. In the QCSS, $u$ and $d$ quarks receive their masses at (multi-)loop level and the smallness of neutrino masses is intimately related to the smallness of the $u$ and $d$ current-quark masses. We examine the predictions of the QCSS for $0 \nu \beta \beta$-decay and reveal the importance of the nuclear mater effects in this case. We find that the genuine no-fine-tuning QCSS favors the normal neutrino-mass ordering and rather narrow ranges of the neutrino masses $m_{1, 2, 3}$. We propose a realization of the QCSS with $\mathbb{Z}_4$ symmetry which predicts these features of the neutrino spectrum.
Graph Representation for Face Analysis in Image Collections

Given an image collection of a social event with a huge number of pictures, it is very useful to have tools that can be used to analyze how the individuals --that are present in the collection-- interact with each other. In this paper, we propose an optimal graph representation that is based on the `connectivity' of them. The connectivity of a pair of subjects gives a score that represents how `connected' they are. It is estimated based on co-occurrence, closeness, facial expressions, and the orientation of the head when they are looking to each other. In our proposed graph, the nodes represent the subjects of the collection, and the edges correspond to their connectivities. The location of the nodes is estimated according to their connectivity (the closer the nodes, the more connected are the subjects). Finally, we developed a graphical user interface in which we can click onto the nodes (or the edges) to display the corresponding images of the collection in which the subject of the nodes (or the connected subjects) are present. We present relevant results by analyzing a wedding celebration, a sitcom video, a volleyball game and images extracted from Twitter given a hashtag. We believe that this tool can be very helpful to detect the existing social relations in an image collection.
Asymmetric Correntropy for Robust Adaptive Filtering

In recent years, correntropy has been successfully applied to robust adaptive filtering to eliminate adverse effects of impulsive noises or outliers. Correntropy is generally defined as the expectation of a Gaussian kernel between two random variables. This definition is reasonable when the error between the two random variables is symmetrically distributed around zero. For the case of asymmetric error distribution, the symmetric Gaussian kernel is however inappropriate and cannot adapt to the error distribution well. To address this problem, in this brief we propose a new variant of correntropy, named asymmetric correntropy, which uses an asymmetric Gaussian model as the kernel function. In addition, a robust adaptive filtering algorithm based on asymmetric correntropy is developed and its steady-state convergence performance is analyzed. Simulations are provided to confirm the theoretical results and good performance of the proposed algorithm.
Structural, Electronic and Elastic Properties of zincblende III-Arsenide Binary Compounds: First-Principles Study

First-principles calculations were performed, and the results from the study of structural, electronic and elastic properties of zincblende III-arsenide binary compounds (BAs, AlAs, GaAs and InAs) are presented. These properties have been calculated using an ab initio pseudopotential method based on density functional theory (DFT) with the local density approximation (LDA) for the exchange-correlation potential. The results obtained for the calculated properties have been compared with experimental data and other computational works. It has also been found that our results with LDA are in good agreement with other computational work wherever these are available.
Constraints on long-lived light scalars with flavor-changing couplings and the KOTO anomaly

Recently, the KOTO experiment at J-PARC has observed three anomalous events in the flavor-changing rare decay $K_L \to \pi^0 \nu \bar\nu$, which indicates that the corresponding branching ratio is almost two orders of magnitude larger than the Standard Model (SM) prediction. Taking this intriguing result at face value, we explore model implications of its viable explanation by a long-lived light SM-singlet scalar ($S$) emission, i.e. $K_L \to \pi^0 S$, with $S$ decaying outside the KOTO detector. We derive constraints on the parameter space of such a light scalar in the context of three simple models: (i) a real singlet scalar extension of the SM; (ii) a $B-L$ extension where neutrino masses arise via type-I seesaw mechanism from $B-L$ breaking; and (iii) a TeV-scale left-right symmetric model. The flavor-changing couplings needed to explain the KOTO excess in models (i) and (ii) originate from tree-level mixing of the scalar with SM Higgs field ($h$), and in model (iii), from the mixing of $S$ and $h$ with the neutral component of the heavy bidoublet Higgs field. After taking into account the stringent constraints from high-precision searches for flavor-changing charged and neutral kaon decays at NA62, E949, KOTO and CHARM experiments, as well as the astrophysical and cosmological constraints on a light scalar, such as those from supernova energy loss, big bang nucleosynthesis and relativistic degrees of freedom, we find that the light scalar interpretation of the KOTO excess is allowed in all these models. Parts of the parameter range can be tested in future NA62 and DUNE experiments.
AdaSample: Adaptive Sampling of Hard Positives for Descriptor Learning

Triplet loss has been widely employed in a wide range of computer vision tasks, including local descriptor learning. The effectiveness of the triplet loss heavily relies on the triplet selection, in which a common practice is to first sample intra-class patches (positives) from the dataset for batch construction and then mine in-batch negatives to form triplets. For high-informativeness triplet collection, researchers mostly focus on mining hard negatives in the second stage, while paying relatively less attention to constructing informative batches. To alleviate this issue, we propose AdaSample, an adaptive online batch sampler, in this paper. Specifically, hard positives are sampled based on their informativeness. In this way, we formulate a hardness-aware positive mining pipeline within a novel maximum loss minimization training protocol. The efficacy of the proposed method is evaluated on several standard benchmarks, where it demonstrates a significant and consistent performance gain on top of the existing strong baselines.
A Simple Distortion Calibration method for Wide-Angle Lenses Based on Fringe-pattern Phase Analysis

A distortion calibration method for wide-angle lens is proposed based on fringe-pattern phase analysis. Firstly, according to the experimental result of the radial distortion of the image not related to the recording depth of field, but depending on the field of view angle of the wide-angle lens imaging system, two-dimensional image distortion calibration is need to be considered. Four standard sinusoidal fringe-patterns with phase shift step of , which are used as calibration templates, are shown on a Liquid Crystal Display screen, and captured by the wide-angle lens imaging system. A four-step phase-shifting method is employed to obtain the radial phase distribution of the distorted fringe-pattern. Wavelet analysis is applied for the analysis of the instantaneous frequency to show the fundamental frequency of the fringe-pattern in the central region being unchanged. Performing numerical calculation by the central 9 points of the central row of the fringe-pattern, we can get the undistorted radial phase distribution, so, the radial modulated phase is computed. Finally, the radial distortion distribution is determined according to the radial modulated phase. By employing a bilinear interpolation algorithm, the wide-angle lens image calibration is achieved. There is no need to establish any kind of image distortion model for the proposed method. There is no projecting system in the experimental apparatus, which avoids projection shadow problems, and no need to align with the center of the template for distortion measurement for the proposed method. Theoretical description, numerical simulation and experimental results show that the proposed method is simple, automatic and effective.
