Using location and motion statistics for the localization of moving objects in multiple camera surveillance videos

The aim of the paper is to present an approach for the localization of moving objects in a multi-camera system that is based on the estimation of observed objects' possible groundplane locations and motion statistics aggregation. It is flexible, it can handle arbitrary number of cameras. It uses only location and motion statistics and do not depend on appearance information. Due to its statistical nature the proposed method efficiently handles such challenging situations as changes in viewpoint, occlusions due to view variations, background clutter and crowd.
Motif Spotting in an Alapana in Carnatic Music

This work addresses the problem of melodic motif spotting, given a query, in Carnatic music. Melody in Carnatic music is based on the concept of raga. Melodic motifs are signature phrases which give a raga its identity. They are also the fundamental units that enable extempore elaborations of a raga. In this paper, an attempt is made to spot typical melodic motifs of a raga queried in a musical piece using a two pass dynamic programming approach, with pitch as the basic feature. In the first pass, the rough longest common subsequence (RLCS) matching is performed between the saddle points of the pitch contours of the reference motif and the musical piece. These saddle points corresponding to quasi-stationary points of the motifs, are relevant entities of the raga. Multiple sequences are identified in this step, not all of which correspond to the the motif that is queried. To reduce the false alarms, in the second pass a fine search using RLCS is performed between the continuous pitch contours of the reference motif and the subsequences obtained in the first pass. The proposed methodology is validated by testing on Alapanas of 20 different musicians.
Asymmetrical Effects of BI-Anisotropic Substrate-Superstrate Sandwich Structure on Patch Resonator

Few works on symmetric and asymmetric dielectrics have been published, speciflcally the case of chiral and bi-isotropic media. For this reason and taking into account the complexity of the studied environment, this paper treats the asymmetrical efiects on the resonant frequency and the bandwidth of a rectangular microstrip patch antenna in a complex bi-anisotropic substrate-superstrate conflguration. This structure is studied theoretically, and the obtained results are discussed and commented. The numerical analysis used in this paper is mainly employed in order to obtain original results. The originality of this work is presented by the bianisotropic chiral asymmetry and the combined efiect of the substrate and the superstrate.
Vascular endothelial cells cultured from patients with cerebral or uncomplicated malaria exhibit differential reactivity to TNF

Plasmodium falciparum malaria is a major cause of morbidity and mortality in African children, and factors that determine the development of uncomplicated (UM) versus cerebral malaria (CM) are not fully understood. We studied the ex vivo responsiveness of microvascular endothelial cells to pro‐inflammatory stimulation and compared the findings between CM and UM patients. In patients with fatal disease we compared the properties of vascular endothelial cells cultured from brain tissue to those cultured from subcutaneous tissue, and found them to be very similar. We then isolated, purified and cultured primary endothelial cells from aspirated subcutaneous tissue of patients with CM (ECCM) or UM (ECUM) and confirmed the identity of the cells before analysis. Upon TNF stimulation in vitro, ECCM displayed a significantly higher capacity to upregulate ICAM‐1, VCAM‐1 and CD61 and to produce IL‐6 and MCP‐1 but not RANTES compared with ECUM. The shedding of endothelial microparticles, a recently described parameter of severity in CM, and the cellular level of activated caspase‐3 were both significantly greater in ECCM than in ECUM. These data suggest that inter‐individual differences in the endothelial inflammatory response to TNF may be an additional factor influencing the clinical course of malaria.
AFRICAN HUNTER-GATHERERS: SURVIVAL, HISTORY, AND THE POLITICS OF IDENTITY

Given the continent's ongoing crises, African hunter-gathgerers have been remarkably successful at surviving difficult times. They have faced war in Namibia, Angola, and the Congo, genocide in Rwanda, and economic difficulties almost everywhere else. Through the last three decades San, Pygmy, Hadza, Okiek, Mikea, and other foragers have sought to maintain coherent societies and systems of meaning and identity in the face of great odds, at times aided by sympathetic outsiders. This paper will explore the challenges they have faced and their responses, while atempting to situate these diverse peoples within the broader historical and political currents of the Twentieth century.
Effects of different forms of chitosan on intercellular junctions of mouse fibroblasts in vitro

Chitosan is a linear polysaccharide that has many biomedical applications. We compared the effects of chitosan, in both solution and membranous form, on intercellular adhesion of Swiss 3T3 mouse fibroblasts. Cells were grown as spheroidal cell cultures. Some control cell spheroids were cultured without chitosan and two experimental groups were cultured with chitosan. Chitosan in solution was used for one experimental group and chitosan in membranous form was used for the other. For each group, intercellular adhesion was investigated on days 5 and 10 of culture. Transmission electron microscopy revealed well-defined cellular projections that were more prominent in cells exposed to either membranous or solution forms of chitosan than to the chitosan-free control. Immunocytochemical staining of ICAM-1 and e-cadherin was used to determine the development of intercellular junctions. Compared to the weakly stained control, strong reactions were observed in both chitosan exposed groups at both 5 and 10 days. Cells were treated with 5-bromo-2-deoxyuridine (BrdU) and incubated with anti-BrdU primary antibody to assess proliferation. Both the solution and membranous forms of chitosan increased proliferation at both 5 and 10 days. Cellular viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). The MTT assay indicated high cell viability; maximum viability was obtained with the solution form of chitosan at day 5. Chitosan exposure increased the number of intercellular junctions and showed a significant proliferative effect on 3T3 mouse fibroblasts.
Two-Year Evaluation of a Vocational Support Program for Adults on the Autism Spectrum

In this article the authors provide a description and evaluation of a vocational support program for adults with autism spectrum disorders (ASD). They followed 9 participants through 2 years of the program. Increases in employment rates and income were found for program participants, and 7 participants retained their initial job placements through the 2-year period. Employers rated program participants highly on a range of important job skills, although these individuals continued to experience social challenges in the workplace. Case notes offer further insight into the experiences of adults with ASD in the workplace. Overall, the results suggest that individuals on the autism spectrum can be successful in competitive, entry-level employment.
[Analysis of a group of HIV positive women who gave birth in the Czech Republic].

OBJECTIVE An analysis of HIV positive women who gave birth between 1st January 1985 to 31st December 2006 in the Czech Republic. SUBJECT A retrospective descriptive analysis. SETTING Teaching Hospital Bulovka, 1st Faculty of Medicine, Charles University, Prague. SUBJECT AND METHODS The study included HIV positive women that gave birth between 1st January 1985 to 31st December 2006 at Bulovka hospital. The group of 62 HIV positive women (including 7 secundiparae) gave birth to 71 new-borns (twice twins). The deliveries were performed by C-section. We interrupted breast-feeding by all these women. RESULTS All new-borns were born alive, no one had Apgar score less than 7 at five minutes. No congenital disorders were found. Three new-borns were transfered to Intensive care unit for new-born babies, two due to dysmaturity and one due to abstinence syndrome. 3 new-borns out of total 71 new-borns were HIV positive (4.2%). CONCLUSION Routine prenatal screening for HIV and high-quality cooperation between obstetricians and infection control doctors are the basic condition of low rate of vertical trasmission HIV infection in the Czech Republic.
Performance Assessment for Mastoidectomy: State of the Art Review

Objective The aim of this report is to provide a review of the current literature for assessment of performance for mastoidectomy, to identify the current assessment tools available in the literature, and to summarize the evidence for their validity. Data Sources The MEDLINE database was accessed via PubMed. Review Methods Inclusion criteria consisted of English-language published articles that reported use of a mastoidectomy performance assessment tool. Studies ranged from 2007 to November 2015 and were divided into 2 groups: intraoperative assessments and those performed with simulation (cadaveric laboratory or virtual reality). Studies that contained specific reliability analyses were also highlighted. For each publication, validity evidence data were analyzed and interpreted according to conceptual definitions provided in a recent systematic review on the modern framework of validity evidence. Conclusions Twenty-three studies were identified that met our inclusion criteria for review, including 4 intraoperative objective assessment studies, 5 cadaveric studies, 10 virtual reality simulation studies, and 4 that used both cadaveric assessment and virtual reality. Implications for Practice A review of the literature revealed a wide variety of mastoidectomy assessment tools and varying levels of reliability and validity evidence. The assessment tool developed at Johns Hopkins possesses the most validity evidence of those reviewed. However, a number of agreed-on specific metrics could be integrated into a standardized assessment instrument to be used nationally. A universally agreed-on assessment tool will provide a means for developing standardized benchmarks for performing mastoid surgery.
Angiotensin II activates pp60c-src in vascular smooth muscle cells.

The angiotensin II type-1 (AT1) receptor, a G protein-coupled receptor, lacks intrinsic kinase activity. However, recent data show that angiotensin II (Ang II) stimulates tyrosine phosphorylation of phospholipase C-gamma 1 (PLC-gamma 1), Stat91 (one of the signal transducers and activators of transcription), and paxillin in vascular smooth muscle cells. The tyrosine kinases responsible for these phosphorylation events are unknown. Src family kinases have been shown to phosphorylate PLC-gamma 1 and to be activated by G protein-coupled receptors. We hypothesized that pp60c-src associates with the AT1 receptor and is activated after Ang II stimulation of smooth muscle cells. We immunoprecipitated pp60c-src from Ang II-stimulated vascular smooth muscle cells and measured pp60c-src activity by autophosphorylation and by phosphorylation of enolase. Both assays demonstrated an approximately threefold increase in pp60c-src activity within 1 minute. A similar increase in Ang II-stimulated pp60c-src activity was observed in Chinese hamster ovary cells transfected with the AT1 receptor but not in untransfected cells. These data are the first to show that pp60c-src is activated by Ang II. To determine if pp60c-src associated with the AT1 receptor, the AT1 receptor was immunoprecipitated (with two different antibodies), and Western blots were performed with two different anti-pp60c-src antibodies. No pp60c-src was detected. In addition, direct interaction between the AT1 receptor and pp60c-src could not be demonstrated by using a glutathione S-transferase (GST)-AT1 fusion protein to bind proteins from cell lysates stimulated by Ang II.

Model of bidirectional interface converter for storage devices

Nowadays world alternative energy sources become more popular. They have a lot advantages like low pollution level, independence of main grid although alternative energy sources have disadvantages and main of them is the unpredictability and inconsistency produced energy. This problem solving is use energy storage devices. Choice of storage devices depends on application. Sometimes flexible solution is necessary. For this purpose was created topology of universal converter. The model of this topology was built in MATLAB Simulink environment. Control system was made although. Result of simulation satisfied. Converter system can stabilize voltage of battery and supercapacitor. Advantages of this topology are: absence of bulky and expensive reactive components. Disadvantages of this topology are difficult control system and a lot of transistors.
Archipelago: A Floorplan Optimized for Concurrent Multiple Applications on Network-on-Chip

In practice, a chip multiprocessor (CMP) with many nodes often runs multiple applications simultaneously and nodes allocated to different applications seldom communicate. Leveraging the non-uniformity of communication, it is possible to optimize the Network-on-Chip (NoC) performance for the case of single chip running multiple applications through reducing the physical links lengths between nodes which tend to be allocated to the same application. In this paper, we propose a novel, nearly zero-cost floor plan method called Archipelago which rearranges the lengths of physical links by flipping hard IP of nodes. With communication monitoring and dynamic thread scheduling, Archipelago significantly reduces the average latency of NoC for concurrent multiple small- and medium-size applications. Experimental results show that Archipelago averagely reduces the packet latency by 19.10% and maximum to 24.4% for three-node applications on 4 × 4 mesh NoC.
North-American speed limit sign detection and recognition for smart cars

Traffic sign detection and recognition system is becoming an essential component of smart cars. Speed-Limit Sign (SLS) is one of the most important traffic signs, since it is used to regulate the speed of vehicles in downtown and highways. The recognition of SLS by drivers is mandatory. In this paper, we investigate SLS detection and recognition system. We focus on North-American speed limit signs, including Canadian and U.S. signs. A modified version of Histogram of Oriented Gradients (HOG) is used to detect and recognize SLS through a set of two-level SVM-based classifiers. Moreover, we build our online database called North-American Speed Limit Signs (NASLS) which includes four SLS categories; white, yellow, black and orange signs. We show through an extensive set of experiments that our system achieves an accuracy of more than 94% of SLS recognition.
Morphological changes, surface receptors and phagocytic potential of fowl mono‐nuclear phagocytes and thrombocytes in vivo and in vitro

TISSUE cultures of mononuclear phagocytes from the blood of Gallus gallus has been used since the beginning of this century as an in vitro model for the study of macrophages (Foot, 1913; Carrel1 and Ebeling, 1922; Lewis, 1925). Sutton and Weiss (1966) have shown by ultrastructural methods the transformation in vitro of mononuclear cells from the blood of the chicken into macrophages, epithelioid cells and macrophage polykaryons. The monocytic origin of macrophages and their derivatives in chronic lesions in mammals is well established (Spector and Mariano, 1975). The studies of Nair (1973) demonstrate that in chronic inflammatory lesions in fowls as in mammals, macrophages, epithelioid cells and macrophage polykaryons are derived from circulating blood cells. Although the kinetics of macrophages in chronic lesions of mammalia and birds are comparable, the inflammatory process in the latter presents some distinct characteristics. A large number of irritants, which can at the most cause an acute inflammatory response in mammals, induces a chronic type of lesion in birds with the development of epithelioid and multinucleated cells (Jortner and Adams, 1971 ; Nair, 1973). Furthermore, the necrotic centre of these lesions, depending upon the age of the granuloma, is similar to the caseous necrosis of tuberculosis (Gross, 1972). The possibility that differences in macrophage behaviour might underlie some of these characteristics prompted this study.
Hybrid Automata and ε-Analysis on a Neural Oscillator

In this paper we propose a hybrid model of a neural oscillator, obtained by partially discretizing a well-known continuous model. Our construction points out that in this case the standard techniques, based on replacing sigmoids with step functions, is not satisfactory. Then, we study the hybrid model through both symbolic methods and approximation techniques. This last analysis, in particular, allows us to show the differences between the considered approximation approaches. Finally, we focus on approximations via e-semantics, proving how these can be computed in practice.
Perceptual grouping of circular arcs under projection

The world (both natural and man-made) is constrained by physical laws to a finite number of basic patterns. Certain three dimensional relationships between features in a scene give rise to two dimensional relationships that are relatively viewpoint invariant and can be distinguished as non-accidental. Thus, those regularities observable in the image arise not by accident, but are projections of real regularities in the scene. The Gestalt movement proposed that the human visual system applied the principles of perceptual organisation to group image features manifesting those regularities. These were used to recover three dimensional structure from two dimensional views, providing cues to models for scene interpretation.
Dynamic TurboFLASH subtraction technique for contrast-enhanced MR imaging of the prostate: correlation with histopathologic results.

PURPOSE To assess whether a TurboFLASH (fast low-angle shot) magnetic resonance (MR) sequence can improve the accuracy of fast spin-echo (SE) endorectal coil MR imaging in the staging and localization of prostate cancer. MATERIALS AND METHODS In 57 patients with prostate cancer, MR imaging was performed with the following sequences: T1-weighted SE, T2-weighted fast SE, single-section gadolinium-enhanced dynamic subtracted TurboFLASH (one image every 1.25 or 2.5 seconds), and late-phase gadolinium-enhanced T1-weighted SE. Retrospectively, two blinded independent readers graded onset and steepest slope of enhancement and assessed tumor involvement and capsular penetration. MR findings were correlated with histopathologic results. RESULTS On TurboFLASH images, prostate cancer was characterized by early and rapidly accelerating enhancement compared with that of surrounding tissues. Average sensitivity, specificity, and accuracy for detection of tumor involvement for the two readers with TurboFLASH images were 73.5%, 81.0%, and 77.5%. These values with fast SE images were 57.5%, 80.5%, and 72.0%. Depiction of capsular penetration and delineation and staging of tumor were better when TurboFLASH images were included with fast SE images. Differences between the two sequences, however, were not statistically significant. CONCLUSION Because the TurboFLASH sequence did not statistically significantly improve tumor localization and staging results, routine use is not recommended. The technique may be useful for selected patients with equivocal evidence of capsular penetration.
High-Content Screening of Raw Actinomycete Extracts for the Identification of Antituberculosis Activities

The feasibility and relevance of screening a library of raw actinomycete extracts (ECUM library) for the identification of antituberculosis activities was assessed on 11,088 extracts using a multiple-screening approach. Each extract was first tested at two concentrations against noninfected macrophages as a control, then against Mycobacterium tuberculosis growing in broth medium as well as infecting murine macrophages. The screening results indicated a library of good quality with an apparent low proportion of cytotoxic extracts. A correlation was found between both bacterial assays, but the intracellular assay showed limitations due to low rates of cell survival. Several extracts of interest were highlighted by this multiple screening. A focus on the strain producing the two most effective revealed similarities with known producers of active molecules, suggesting the possibility of selecting relevant extracts using this strategy.
A Economia Moral do Recrutamento Militar no Império Brasileiro

The subject of this article is the dynamics of military recruitment in Imperial Brazil, particularly before the Paraguayan War. It is argued that, in the field of military service, the imperial State depended on indirect forms of governance, specially the liturgies of the local notables. The moral and material bases of honorary administration imposed many obstacles to governmental action, promoting the local translation of recruitment. The honorary administration and the orders of privilege circumscribed the limits and possibilities of recruitment in the Empire. The article describes the local operation of recruitment as a complex game combining strategies of the central authority, local notables and probable recruits immersed in protection networks.
Compressive Sensing Improvement Based on Projection Replacement in Measurement Space

Traditional CS algorithm is built based on the hypothesis that there exits measurement noise, which means that these algorithm rebuild the significant coefficients in the signal and ignore the small coefficients as noise. However, the reconstructed result does not satisfy the measurement equation any more. In this paper, we proposed a method that replace the projection of the reconstructed result in the orthogonal complement space of the measurement space. Better images are reconstructed than the conventional OMP and TSW-CS methods. The experimental results show the advantage of our proposed revised algorithm in the low noise environment.
