Automatic detection of regions of interest in complex video sequences

Studies of visual attention and eye movements have shown that people generally attend to only a few areas in typical scenes. These areas are commonly referred to as regions of interest (ROIs). When scenes are viewed with the same context and motivation, these ROIs are often highly correlated amongst different people, motivating the development of computational models of visual attention. This paper describes a novel model of visual attention designed to provide an accurate and robust prediction of a viewer's locus of attention across a wide range of typical video content. The model has been calibrated and verified using data gathered in an experiment in which the eye movements of 24 viewers were recorded while viewing material form a large database of still and video scenes. Certain characteristics of the scene content, such as moving objects, people, foreground and centrally-located objects, were found to exert a strong influence on viewers' attention. The results of comparing model predictions to experimental data demonstrate a strong correlation between the predicted ROIs and viewers' fixations.
Finite Element Analysis of Mobile-bearing Unicompartmental Knee Arthroplasty: The Influence of Tibial Component Coronal Alignment

Background: Controversies about the rational positioning of the tibial component in unicompartmental knee arthroplasty (UKA) still exist. Previous finite element (FE) studies were rare, and the results varied. This FE study aimed to analyze the influence of the tibial component coronal alignment on knee biomechanics in mobile-bearing UKA and find a ration range of inclination angles. Methods: A three-dimensional FE model of the intact knee was constructed from image data of one normal subject. A 1000 N compressive load was applied to the intact knee model for validating. Then a set of eleven UKA FE models was developed with the coronal inclination angles of the tibial tray ranging from 10° valgus to 10° varus. Tibial bone stresses and strains, contact pressures and load distribution in all UKA models were calculated and analyzed under the unified loading and boundary conditions. Results: Load distribution, contact pressures, and contact areas in intact knee model were validated. In UKA models, von Mises stress and compressive strain at proximal medial cortical bone increased significantly as the tibial tray was in valgus inclination >4°, which may increase the risk of residual pain. Compressive strains at tibial keel slot were above the high threshold with varus inclination >4°, which may result in greater risk of component migration. Tibial bone resection corner acted as a strain-raiser regardless of the inclination angles. Compressive strains at the resected surface slightly changed with the varying inclinations and were not supposed to induce bone resorption and component loosening. Contact pressures and load percentage in lateral compartment increased with the more varus inclination, which may lead to osteoarthritis progression. Conclusions: Static knee biomechanics after UKA can be greatly affected by tibial component coronal alignment. A range from 4° valgus to 4° varus inclination of tibial component can be recommended in mobile-bearing UKA.
Acetic acid iontophoresis and ultrasound for the treatment of calcifying tendinitis of the shoulder: a randomized control trial.

OBJECTIVE To assess the effects of acetic acid iontophoresis (AAI) and ultrasound on calcifying tendinitis of the shoulder, and to determine the relation between changes in the radiological measures of calcium deposit (CD) and shoulder function. DESIGN Randomized control trial. SETTING General community, private practice. PATIENTS Twenty-two adults (7 men, 15 women) with a calcifying tendinitis of the shoulder, without associated conditions, stratified according to the type of lesions (X-ray: type I, fleecy appearance: type II, homogeneous), were randomly allocated to an experimental (EXP, n = 11) or to a control (CTL, n = 10) group. INTERVENTIONS CTL group, no treatment; EXP group, nine treatments including AAI (5% acetic acid solution via the negative electrode, 5mA galvanic current, 20 minutes) followed by continuous ultrasound (0.8w/cm2, 1MHz, 5 minutes). MAIN OUTCOME MEASURES Area and density of the CD, passive shoulder abduction (range of motion [ROM]), pain intensity. RESULTS Significant reduction in the area and density of CD (ANCOVA, p = .01 and .03) over time in the EXP and CTL groups, but no significant difference between groups for any of the variables measured. The decrease in the area of CD in type I lesions (n = 5) was larger (Mann-Whitney U test, p < .01) than in type II (n = 16) lesions. The relation was stronger (rs = .90) between changes in area and density of CD than between ROM and pain (rs = -.67). Correlations were weak (rs = .21 to .41) between radiological and functional changes. CONCLUSION The reduction in CD area and density likely results from a natural process rather than treatment (AAI and ultrasound); type I lesions (resorptive phase) are more likely to display resorption of the CD than type II lesions (formative phase). Reduction of the CD area does not necessary result in a functional improvement.

Modelling and Implementation of ITWS: An ultimate solution to ITS

Casualties due to traffic accidents are increasing day by day. Think of this message being displayed on your computer screen while you were driving "there's a possibility of collision with a car in the next few minutes if you go on driving with this speed and direction". Our research is intended towards developing collision avoidance architecture for the latest Intelligent Transport System. The exchange of safety messages among vehicles and with infrastructure devices poses major challenges. Specially, safety messages have to be adaptively distributed within a certain range of a basically unbounded system. These messages are to be well coordinated and processed via different algorithms. The purpose of the paper is to discuss the ITWS (intelligent transportation warning system), we have discussed the Assisted Global Positioning System(AGPS) system providing additional positioning information at variable conditions. We have also discussed study the Data fusion and kalaman filter in details. The performance of kalman filter and output are discussed. Hardware realization of this model is achieved through software defined radio (SDR).
Feature Selection for Fast Face Matching

In this paper, we present a novel algorithm performing face image comparison. Ababoosting is applied to find the right features in the offline phase and use them to determine similarity quickly while online. We build hierarchical classifiers to speed up the online matching process. Extension to our method is described to count for misalignment images, thus shifted images can be handled correctly. Experiments show that we achieve good accuracy at a high speed.
Dorsomedial prefrontal cortex activity predicts the accuracy in estimating others' preferences

The ability to accurately estimate another person's preferences is crucial for a successful social life. In daily interactions, we often do this on the basis of minimal information. The aims of the present study were (a) to examine whether people can accurately judge others based only on a brief exposure to their appearances, and (b) to reveal the underlying neural mechanisms with functional magnetic resonance imaging (fMRI). Participants were asked to make guesses about unfamiliar target individuals' preferences for various items after looking at their faces for 3 s. The behavioral results showed that participants estimated others' preferences above chance level. The fMRI data revealed that higher accuracy in preference estimation was associated with greater activity in the dorsomedial prefrontal cortex (DMPFC) when participants were guessing the targets' preferences relative to thinking about their own preferences. These findings suggest that accurate estimations of others' preferences may require increased activity in the DMPFC. A functional connectivity analysis revealed that higher accuracy in preference estimation was related to increased functional connectivity between the DMPFC and the brain regions that are known to be involved in theory of mind processing, such as the temporoparietal junction (TPJ) and the posterior cingulate cortex (PCC)/precuneus, during correct vs. incorrect guessing trials. On the contrary, the tendency to refer to self-preferences when estimating others' preference was related to greater activity in the ventromedial prefrontal cortex. These findings imply that the DMPFC may be a core region in estimating the preferences of others and that higher accuracy may require stronger communication between the DMPFC and the TPJ and PCC/precuneus, part of a neural network known to be engaged in mentalizing.
Hindi generation from interlingua

This paper reports our work on generating Hindi sentences from an interlingua representation called Universal Networking Language (UNL). UNL represents knowledge in semantic net like graphs which contain disambiguated words, binary semantic relations, and speech act like attributes associated with the words. Assisted by a semantically rich lexicon, a priority-matrix of syntax plan, and elaborate morphology synthesis rules, we produce fluent Hindi sentences which also meet the adequacy requirement with respect to the reference sentences, and the faithfulness requirement with respect to the semantic graphs. The system has been tested on agricultural corpora, and the system generated sentences were scored by a team of evaluators. The BLEU scores against the reference sentences have been computed. The results show that our system is able to generate slightly flawed but easy to understand sentences that convey most of the meaning. We observe strong correlation between the fluency scores and the BLEU scores, as well as between fluency and the adequacy scores. Since fluency evaluation does not require reference translation, this correlation facilitates large scale evaluation of our system without translating large number of UNL sentences. This system is a step towards machine translation involving Hindi as the target language. Our approach is also adoptable to the generation of other languages, in particular Indian languages.
Opportunities and challenges for large scale 3D printing of complex parts

Additive manufacturing (AM) allows designers to build 3D parts of almost any geometry and streamline the process of moving from initial design to prototype in a shortened timeframe. However the existing technologies are limited to small size parts due only to high resolution of the generally produced designs. If a very large part with typical layer resolutions of 0.2mm is produced, the time required for making such a part will be prohibitive. In addition, the material costs will excessive and the machine size will need to be gigantic. In large scale printing the material and the high costs restrict testing on the actual structures and lends itself to the use of numerical or analytical studies of the structures before actual printing. In this paper we analyse the current state of the 3D printing within the boundaries of large scale printing and present a possible solution with numerical simulations.
Interaction debugging: an integral approach to analyze human-robot interaction

Along with the development of interactive robots, controlled experiments and field trials are regularly conducted to stage human-robot interaction. Experience in this field has shown that analyzing human-robot interaction for evaluation purposes fosters the development of improved systems and the generation of new knowledge. In this paper, we present the interaction debugging approach, which is based on the collection and analysis of data from robots and their environment. Considering the multimodality of robotic technology, often only audio and video are insufficient for detailed analysis of human-robot interaction. Therefore, in our analysis we integrate multimodal information using audio, video, sensory data, and intermediate variables. An important aspect of the interaction debugging approach is using a tool called Interaction Debugger to analyze data. By supporting user-friendly data presentation, annotation and navigation, Interaction Debugger enables fine-grained inspection of human-robot interaction. The main goal of this paper is to address how an integral approach to the analysis of human-robot interaction can be adopted. This is demonstrated by three case studies.
Race-related differences in antibody responses to the inactivated influenza vaccine are linked to distinct pre-vaccination gene expression profiles in blood

We conducted a 5-year study analyzing antibody and B cell responses to the influenza A virus components of the inactivated influenza vaccine, trivalent (IIV3) or quadrivalent (IIV4) in younger (aged 35-45) and aged (≥65 years of age) Caucasian and African American individuals. Antibody titers to the two influenza A virus strains, distribution of circulating B cell subsets and the blood transcriptome were tested at baseline and after vaccination while expression of immunoregulatory markers on B cells were analyzed at baseline. African Americans mounted higher virus neutralizing and IgG antibody responses to the H1N1 component of IIV3 or 4 compared to Caucasians. African Americans had higher levels of circulating B cell subsets compared to Caucasians. Expression of two co-regulators, i.e., programmed death (PD)-1 and the B and T cell attenuator (BTLA) were differentially expressed in the two cohorts. Race-related differences were caused by samples from younger African Americans, while results obtained with samples of aged African Americans were similar to those of aged Caucasians. Gene expression profiling by Illumina arrays revealed highly significant differences in 1368 probes at baseline between Caucasians and African Americans although samples from both cohorts showed comparable changes in transcriptome following vaccination. Genes differently expressed between samples from African Americans and Caucasians regardless of age were enriched for myeloid genes, while the transcripts that differed in expression between younger African Americans and younger Caucasians were enriched for those specific for B-cells.
CAD models of dispersion and losses for multilayer coplanar waveguide

We present the closed-form models of conductor thickness dependent dispersive line parameters and losses, of multilayer CPW on isotropic dielectric substrates. The partial capacitance technique has been used for conformal mapping of the multilayered CPW structure. The dispersive empirical expressions for the single-layer CPW from literature are improved to include the finite conductivity and finite conductor thickness in propagation characteristics and losses. The single layer reduction formulation of lossy multilayer CPW is then used to extend the closed-form models developed for computation of line parameters, to multilayer structures. All developed models are verified against the results obtained using the EM-simulators for frequency range 1 GHz – 60 GHz over wide range of parameters. The average deviation of the model against the comparison is 3.5 %.
Robust speaker DOA estimation with single AVS in bispectrum domain

For mobile speech application, speaker DOA estimation accuracy, interference robustness and compact physical size are three key factors. Considering the size, we utilized acoustic vector sensor (AVS) and proposed a DOA estimation algorithm previously [1], offering high accuracy with larger-than-15dB SNR but is deteriorated by nonspeech interferences (NSI). This paper develops a robust speaker DOA estimation algorithm. It is achieved by deriving the intersensor data ratio model of an AVS in bispectrum domain (BISDR) and exploring the favorable properties of bispectrum, such as zero value of Gaussian process and different distribution of speech and NSI. Specifically, a reliable bispectrum mask is generated to guarantee that the speaker DOA cues, derived from BISDR, are robust to NSI in terms of speech sparsity and large bispectrum amplitude of the captured signals. Intensive experiments demonstrate an improved performance of our proposed algorithm under various NSI conditions even when SIR is smaller than 0dB.
Uterine Myoma: A Profile of Nepalese women

Objectives: 1. To determine the most common age and parity for the development of myoma uteri. 2. To find out any relation between age of the last child and the development of myoma uteri. 3. To determine the treatment protocal and outcome of treatment. Materials/methods: Materials/methods: Materials/methods: Materials/methods: Materials/methods: This study was carried out at Nepal Medical College Teaching Hospital from Jan 2001 to 31 st June 2006. All cases of myoma uteri admitted in Gynaecological ward was included. Histological evidence of myoma confirmed the diagnosis. Age, parity and age of the last child, clinical features, surgical procedures and outcome of surgery were considered. Results: A total of 137 cases of myoma uteri was operated during five and half years period. This represented 38.5 %of all abdominal hysterectomy performed during the same period. The mean age was 43.3 years with median parity at 1-3 and the mean age of last child at 12years. Excessive menstrual bleeding 73.0%, abdominal mass and pain 58.4%, dysmenorrhea 18.2% and infertility 7.3% were the common symptoms. Total abdominal hysterectomy was the mainstay of treatment. Patients were happy with the treatment specially those with severe and multiple symptoms Postoperative complications were not significant. There was one death due to pulmonary embolism who had mesothelioma of pleura diagnosed by pleural biopsy before operation. Conclusion: Early marriage and early completion of the family is the social trend in Nepalese society. Myoma is common in 4 th -5 th decade of life in multi parity with the age of last child around 12years. This long standing secondary infertility may be an underlying risk factor in the development of myoma uteri.

Acetylation of Mammalian ADA3 Is Required for Its Functional Roles in Histone Acetylation and Cell Proliferation

ABSTRACT Alteration/deficiency in activation 3 (ADA3) is an essential component of specific histone acetyltransferase (HAT) complexes. We have previously shown that ADA3 is required for establishing global histone acetylation patterns and for normal cell cycle progression (S. Mohibi et al., J Biol Chem 287:29442–29456, 2012, http://dx.doi.org/10.1074/jbc.M112.378901). Here, we report that these functional roles of ADA3 require its acetylation. We show that ADA3 acetylation, which is dynamically regulated in a cell cycle-dependent manner, reflects a balance of coordinated actions of its associated HATs, GCN5, PCAF, and p300, and a new partner that we define, the deacetylase SIRT1. We use mass spectrometry and site-directed mutagenesis to identify major sites of ADA3 acetylated by GCN5 and p300. Acetylation-defective mutants are capable of interacting with HATs and other components of HAT complexes but are deficient in their ability to restore ADA3-dependent global or locus-specific histone acetylation marks and cell proliferation in Ada3-deleted murine embryonic fibroblasts (MEFs). Given the key importance of ADA3-containing HAT complexes in the regulation of various biological processes, including the cell cycle, our study presents a novel mechanism to regulate the function of these complexes through dynamic ADA3 acetylation.
STUDIES ON THE BLOOD PROTEINS

The intoxication which develops as the result of a simple obstruction or a closed intestinal loop is accompanied by definite changes in the coagulable proteins of the blood serum. These changes consist essentially in an alteration in the normal albumin-globulin ratio; the globulin fraction is greatly increased and at times the normal relation of the two fractions may show a complete inversion. The increase in the globulin content of the blood serum is most marked in the animals which show some of the complications met with in loop animals,—rupture of the loop and peritonitis. In the latter conditions especially, the globulin increase is rapid and large. We believe this reaction to be of diagnostic value in acute infections attended by the sudden liberation and absorption of a toxic exudate. Infections and intoxications produced by inflammatory irritants are also accompanied by a rise in the blood globulins. This observation suggests that tissue disintegration with absorption of toxic products is responsible for the changes noted, and that bacterial invasion is important only in as far as it gives rise to toxic substances. Animals which have developed a tolerance to proteose intoxication following the periodic injection of small doses of proteose do not show a globulin increase. These experiments do not support the view that the rise in globulins observed in these experimental conditions is an expression of a resistance or tolerance developed by the animal. From the experimental evidence it seems more probable that the alteration in the partition of the blood protein fractions is one of the results of the metabolic disturbance which has been shown to occur in these conditions.
