Abnormality Detection in Digital Mammogram

— Breast cancer is one of the most common life threatening types of cancer affecting woman. Mammography is an effective screening tool used by the radiologist for breast cancer detection. CAD system is like a spell checker and provides a second opinion for radiologists. The detection performance of the CAD can be improved by using appropriate techniques in digital image processing, machine learning and statistical analysis. The important features associated with cancers are microcalcification clusters, architectural distortions and masses. There are some issues such as poor image quality and shapes of masses leads to the classification of masses a difficult task. An efficient technique that deals with the detection of masses is proposed in this paper. Paper also proposes some new techniques that classify the detected masses to benign or malignant. The proposed techniques use the image datasets from MIAS research database. Proposed methods outperform other techniques in the detection and classification of masses.
An Antimicrobial Metabolite from Bacillus sp.: Significant Activity Against Pathogenic Bacteria Including Multidrug-Resistant Clinical Strains

In this study, the cell free modified tryptone soya broth (pH 7.4 ± 0.2) of Bacillus subtilis URID 12.1 showed significant antimicrobial activity against multidrug-resistant strains of Staphylococcus aureus, S. epidermidis, Streptococcus pyogenes and Enterococcus faecalis. The partially purified antimicrobial molecule was found to be resistant to extremes of pH and temperatures and also to higher concentrations of trypsin and proteinase K. The antimicrobial molecule was purified by a three-step method that included reversed-phase high performance liquid chromatography (RP-HPLC). The minimum inhibitory concentration (MIC) values were determined for 14 species of bacteria using a microbroth dilution technique. The HPLC-purified fraction showed the MICs ranging from 0.5 to 16 μg/ml for methicillin and vancomycin-resistant Staphylococcus aureus (MVRSA) and methicillin-resistant Staphylococcus epidermidis (MRSE) strains. The molecular mass of the antimicrobial compound was determined to be 842.37 Da. The same antimicrobial fraction showed negligible haemolytic activity against human red blood cells even at a concentration as high as 100 μg/ml. Because of its significant antimicrobial activity at low MIC values coupled with its non-haemolytic property, it may prove to be a novel antimicrobial lead molecule.
Extending rCUDA with Support for P2P Memory Copies between Remote GPUs

Although GPUs are being widely adopted in order to noticeably reduce the execution time of many applications, their use presents several side effects such as an increased acquisition cost of the cluster nodes or an increased overall energy consumption. To address these concerns, GPU virtualization frameworks could be used. These frameworks allow accelerated applications to transparently use GPUs located in cluster nodes other than the one executing the program. Furthermore, these frameworks aim to offer the same API as the NVIDIA CUDA Runtime API does, although different frameworks provide different degree of support. In general, and because of the complexity of implementing an efficient mechanism, none of the existing frameworks provides support for memory copies between remote GPUs located in different nodes. In this paper we introduce an efficient mechanism devised for addressing the support for this kind of memory copies among GPUs located in different cluster nodes. Several options are explored and analyzed, such as the use of the GPUDirect RDMA mechanism. We focus our discussion on the rCUDA remote GPU virtualization framework. Results show that is is possible to implement this kind of memory copies in such an efficient way that performance is not reduced with respect to the original performance attained by CUDA when GPUs located in the same cluster node are leveraged.
A comparative study of physical activity level among inpatients with schizophrenia and bipolar disorder

Aims: Regarding the low level of physical activity (PA) in schizophrenia and bipolar disorder (BD), our aim was to compare the level of PA between the two groups. Methods: In this cross-sectional study, 100 patients with schizophrenia and 100 patients with BD were selected through convenience sampling in 2017. The level of PA was assessed using International Physical Activity Questionnaire. Chi-square, extended Fisher's exact, Student's t, and Mann–Whitney tests were applied to analyze the data. Results: Prevalence of low PA in schizophrenic patients and BD was 36.7% and 30.3%, respectively. The frequency of moderate PA was less in schizophrenic patients than that in the BD patients (56.1% and 65.7%, respectively) and vigorous PA was more frequent in schizophrenic patients than the BD individuals (7.1% and 4%, respectively) (P = 0.334). Schizophrenic patients had significantly fewer minutes of PA than that of the BD patients (P = 0.027). Minutes of vigorous PA were higher in schizophrenic patients, while BD patients had more minutes of moderate PA, but these differences were not statistically significant (P > 0.05). BD patients had significantly more walking minutes than that of the schizophrenic patients (P = 0.05). Conclusion: The prevalence of inactivity was higher in schizophrenic patients than BD patients. This rate was high in both groups due to hospitalization, factors associated with the disease, or even lack of attention to these patients. Therefore, more attention should be paid to the physical health of these patients; also, psychiatric centers should take preventive and interventional measures in this regard.
Speckle Filtering of Sar Images -a Comparative Study between Complex-wavelet-based and Standard Filters

We present a comparative study between a complex Wavelet Coeecient Shrinkage (WCS) lter and several standard speckle lters that are widely used in the radar imaging community (Lee, Kuan, Frost, Geometric, Kalman, Gamma, etc.). The WCS lter is based on the use of Symmetric Daubechies (SD) wavelets which share the same properties as the real Daubechies wavelets but with an additional symmetry property. The ltering operation is an elliptical soft-thresholding procedure with respect to the principal axes of the 2-D complex wavelet coeecient distributions. Both qualitative and quantitative results (signal to mean square error ratio, equivalent number of looks, edgemap gure of merit) are reported. Tests have been performed using simulated speckle noise as well as real radar images. It is found that the WCS lter performs equally well as the standard lters for low-level noise and slightly outperforms them for higher-level noise.
Encryption Implementation of Rock Cipher Based on FPGA

Abstrct :- Information security systems must provide high levels of correctness, and reliability. The presented implementation is an application for symmetric encryption algorithm which developed by using two keys to encrypt an input block consist of 128 bit. This implementation is developed for the purpose of producing a powerful encryption data. The operation of encryption and decryption required to insert two keys together in order to access the system correctly. Each key expanded randomly to 128 bit and then it used in each round of encryption. The design is based on Field Programmable Gate Array (FPGA) and used VHDL code to implement the design. The simulation results are considered reliable and completely correct.
Integrating the Natural Environment in Social Work Education: Sustainability and Scenario-based Learning

ABSTRACT This article presents an approach to curriculum design that incorporates natural environmental content into social work education using sustainability principles. The curriculum development project outlined here used scenario-based learning (SBL) to integrate sustainability themes into contemporary social work practice challenges. SBL offers a flexible pedagogical strategy to integrate environmental content and explore social complexity. Importantly, it presents eco-social concerns as a central consideration of all contemporary social work practice. IMPLICATIONS The article highlights the value of integrated scholarship in developing graduates’ professional identity as a primary aim of social work education. Scenarios incorporating environmental, economic, and social complexities generated by climate change can be used to integrate environmental content across different fields and practice modalities. Scenario-based curriculum design provides a flexible approach to conceptual and contextual integration of environmental issues and other emerging social challenges.
Managing Knowledge-based Value Systems

The process of differentiating KM both as a business practice and a discipline is in a reflexive situation: it is happening amidst a major transformation of established criteria for the social recognition of a knowledge field. Awareness of this fact by stakeholders in the systematic and sustainable evolution of KM may lead to a conscious management of its current and future identity. An attempt to develop a systemic perspective of the field of Knowledge‐based Value Systems at the Center for Knowledge Systems (CKS), an R&D unit at Instituto Tecnologico de Monterrey, Mexico, is introduced.
Element-wise mixed implicit-explicit integration for stable dynamic simulation of deformable objects

In order to evolve a deformable object in time, the underlying equations of motion have to be numerically integrated. This is commonly done by employing either an explicit or an implicit integration scheme. While explicit methods are only stable for small time steps, implicit methods are unconditionally stable. In this paper, we present a novel methodology to combine explicit and implicit linear integration approaches, based on element-wise stability considerations. First, we detect the ill-shaped simulation elements which hinder the stable explicit integration of the element nodes as a pre-computation step. These nodes are then simulated implicitly, while the remaining parts of the mesh are explicitly integrated. As a consequence, larger integration time steps than in purely explicit methods are possible, while the computation time per step is smaller than in purely implicit integration. During modifications such as cutting or fracturing, only newly created or modified elements need to be reevaluated, thus making the technique usable in real-time simulations. In addition, our method reduces problems due to numerical dissipation.
Osp(N |4) supermultiplets as conformal superfields on ∂AdS 4 and the generic form of N = 2, d = 3 gauge theories ∗†

In this paper we fill a necessary gap in order to realize an explicit comparison between the Kaluza-Klein spectra of supergravity compactified on AdS 4 × X 7 and superconformal field theories living on the worldvolume of M2-branes. On the algebraic side we consider the superalgebra Osp ( | 4) and we study the double interpretation of its unitary irreducible representations either as supermultiplets of particle states in the bulk or as a conformal superfield on the boundary. On the Lagrangian field theory side we construct, using rheonomy rather than superfield techniques, the generic form of an = 2, d = 3 gauge theory. Indeed, the superconformal multiplets are supposed to be composite operators in a suitable gauge theory.
Heritage Acculturation Is Associated With Contextual Factors at Four Different Levels of Proximity

What factors explain the extent to which members of cultural minorities maintain their heritage cultural engagement? Although this process, called heritage acculturation, has significant implications for adjustment, we know little about its antecedents. The present work sought to address two shortcomings of acculturation research: (a) the need to characterize antecedents of acculturation orientations and (b) the need to consider acculturation as a contextual phenomenon. Some studies have documented associations between acculturation and specific contextual variables (e.g., family socialization), but an important feature of this research was to examine the unique contribution of factors at multiple levels of proximity simultaneously. Specifically, this study considered intraindividual, home, social network, and neighborhood-level contextual correlates of heritage acculturation. The overarching hypothesis tested among multicultural university students in Canada (n = 271) was that people whose life contexts are more strongly imbued with heritage cultural influences would report greater heritage acculturation. Results fully supported this hypothesis. Greater heritage language competence, “parental” living arrangements, a more extensive heritage social network, and living in an ethnically denser neighborhood were all related to greater heritage cultural maintenance. Further, only heritage network extensiveness was negatively related to mainstream cultural engagement—attesting to the cultural specificity of these associations. These results suggest that none of the four contextual levels considered here was sufficient on its own to understand participants’ heritage acculturation and that we need a holistic view of the person in her or his multiple contexts when studying acculturation.
Treatment of deep vein thrombosis with oral anticoagulants in patients with malignancy: prospective cohort study.

AIM To assess the outcome of deep vein thrombosis in patients with malignancy after 6 months of oral anticoagulant therapy, and to compare it with international normalized ratio (INR). METHOD Thirty-one patients with malignancy (13 with hematological and 18 with solid tumors) and deep vein thrombosis (29 leg thrombosis and 2 upper extremity thrombosis) were included into a prospective cohort study that lasted from March 2000 until May 2001. The presence of malignant tumors was histologically proved and documented, and deep vein thrombosis was proved by ultrasound or venography. Patients were treated with heparin during the acute phase, and with oral anticoagulant therapy during further 6 months. INRs and ultrasound examination performed during the acute event were repeated one month and 6 months afterwards for the needs of analysis. RESULTS Twenty-four patients concluded the study. Clot resolution was achieved in 13 patients after 6 months of therapy. The patients with INR>2 (n=10) had better clot resolution than those with INR<2 (n=3); p=0.012. There was no statistically significant difference in the outcome of thrombosis with regard to the INR level after a month of therapy (p=0.555). Three patients experienced bleeding, one patient had recurrent thrombosis, and two patients suffered pulmonary embolism. CONCLUSION Appropriate anticoagulation during 6 months after the acute deep vein thrombosis enhances the rate of the complete clot resolution. The INR values can be used as predictive of complete recovery from the thrombosis. Complications are comparable with those reported for patients without malignancy.
Inhibition of Connective Tissue Growth Factor Overexpression in Diabetic Retinopathy by SERPINA3K via Blocking the WNT/β-Catenin Pathway

OBJECTIVE Connective tissue growth factor (CTGF) is a major fibrogenic factor. Increased retinal CTGF levels have been implicated to play a role in diabetic retinopathy. SERPINA3K is a serine proteinase inhibitor, and its levels were decreased in retinas with diabetic retinopathy. The purpose of this study was to investigate the role of SERPINA3K in the regulation of CTGF and fibrogenesis and its mechanism of action. RESEARCH DESIGN AND METHODS Adenovirus expressing SERPINA3K was injected intravitreally into streptozotocin-induced diabetic rats. CTGF expression was measured using Western blot analysis and real-time RT-PCR. Fibrosis was evaluated by quantifying retinal fibronectin using enzyme-linked immunosorbent assay. Wnt pathway activation was determined by phosphorylation of LDL receptor–related protein 6, a coreceptor of Wnt ligands, and stabilization of β-catenin, an essential effector of the canonical Wnt pathway. RESULTS Ad-SERPINA3K attenuated the CTGF and fibronectin overexpression in retinas of diabetic rats. In cultured retinal cells, SERPINA3K blocked the overproduction of CTGF induced by high glucose. Dickkopf-1, a specific Wnt antagonist, also attenuated the high-glucose–induced CTGF overexpression, indicating a role of Wnt signaling in CTGF overexpression in diabetes. Similarly, increased SERPINA3K blocked Wnt pathway activation in diabetic retinas and in cells treated with high glucose. Further, SERPINA3K also attenuated the Wnt3a-induced activation of the canonical Wnt pathway and the overexpression of CTGF. CONCLUSION SERPINA3K is an antifibrogenic factor, and its antifibrogenic activity is through blocking the Wnt pathway. Decreased SERPINA3K levels may contribute to the fibrosis in diabetic retinopathy.
Age Dependence and Isotype Specificity of Influenza Virus Hemagglutinin Stalk-Reactive Antibodies in Humans

ABSTRACT Influenza remains a major global health burden. Seasonal vaccines offer protection but can be rendered less effective when the virus undergoes extensive antigenic drift. Antibodies that target the highly conserved hemagglutinin stalk can protect against drifted viruses, and vaccine constructs designed to induce such antibodies form the basis for a universal influenza virus vaccine approach. In this study, we analyzed baseline and postvaccination serum samples of children (6 to 59 months), adults (18 to 49 years), and elderly individuals (≥65 years) who participated in clinical trials with a recombinant hemagglutinin-based vaccine. We found that baseline IgG and IgA antibodies against the H1 stalk domain correlated with the ages of patients. Children generally had very low baseline titers and did not respond well to the vaccine in terms of making stalk-specific antibodies. Adults showed the highest induction of stalk-specific antibodies, but the elderly had the highest absolute antibody titers against the stalk. Importantly, the stalk antibodies measured by enzyme-linked immunosorbent assay (ELISA) showed neutralizing activity in neutralization assays and protected mice in a passive-transfer model in a stalk titer-dependent manner. Finally, we found similar patterns of stalk-specific antibodies directed against the H3 and influenza B virus hemagglutinins, albeit at lower levels than those measured against the H1 stalk. The relatively high levels of stalk-specific antibodies in the elderly patients may explain the previously reported low influenza virus infection rates in this age group. (This study has been registered at ClinicalTrials.gov under registration no. NCT00336453, NCT00539981, and NCT00395174.) IMPORTANCE The present study provides evidence that titers of broadly neutralizing hemagglutinin stalk-reactive antibodies increase with age, possibly due to repeated exposure to divergent influenza viruses. These relatively high levels of antistalk titers may be responsible for lower circulation rates of influenza viruses in older individuals. Our findings suggest that the level of antistalk antibodies is a good surrogate marker for protection against influenza virus infection. In addition, the levels of antistalk antibodies might determine the breadth of protection against different drifted strains.

MODELING OF THE TOHOKU-OKI 2011 TSUNAMI GENERATION, FAR-FIELD AND COASTAL IMPACT: A MIXED CO-SEISMIC AND SMF SOURCE

Tsunami hazard assessment for future megathrust earthquakes requires that we understand the source mec hanisms and tsunami generation processes for large historical e vents, such as the devastating Tohoku-oki tsunami o f March 11 th 2011. Although associated with a Magnitude 9 earthquake, simulations of the tsunami based solely on th is co-seismic source do not reproduce the elevated runup heights of 40 m along the coast of northern Honshu, nor the wave timing and high frequency wave periods recorded at offshor e GPS and DART buoys. Here, we show that an additional tsunami source associated with a large submarine mass failure (SMF), triggered North-East of the main source after a 2 min. delay, satisfies the necessary observations. T o do so, we model the tsunami sourced from both earthquake and SMF. This dual source reproduces both the recorded onshore runups and the wave heights and wave frequencies recorded at offshore buoys. The significant contrib ution from an SMF to the Tohoku-oki tsunami has important implications for assessing coastal hazard from futu re megathrust earthquake events.
A real-time fast incremental SLAM method for indoor navigation

Recently, numerous efficient approaches to simultaneously localization and mapping (SLAM) based on ground robots have been proposed. However, we may encounter difficulties when applying those algorithms to those systems with higher real-time requirements, such as micro aerial vehicles (MAVs). This paper presents a fast and effective solution to SLAM problems, enables a quadrotor to autonomously explore unknown indoor environments. We propose a probabilistic approach to estimate the position based on scan matching algorithm. The estimation uncertainty is computed by a cost function. Furthermore, Bayesian method is used to update the occupancy probability grid map, which provides an effective way to solve sensor uncertainty. Experimental results carried out by using a laser range sensor on a quadrotor platform in indoor environment show that the incremental SLAM strategy has a superior performance.
A New Model for Error Clustering in Telephone Circuits

This paper proposes a new mathematical model to describe the distribution of the occurrence of errors in data transmission on telephone lines. We suggest: a) that the statistics of telephone errors can be described in terms of an error probability depending solely on the time elapsed since the last occurrence of an error; b) that the distribution of inter-error intervals can be well approximated by a law of Pareto of exponent less than one; the relative number of errors and the equivocation tend, therefore, to zero as the length of the message is increased. The validity of those concepts is demonstrated with the aid of experimental data obtained from the German telephone network. Further consequences, refinements, and uses of the model are described in the body of the paper.
Bilingual Co-Training for Sentiment Classification of Chinese Product Reviews

The lack of reliable Chinese sentiment resources limits research progress on Chinese sentiment classification. However, there are many freely available English sentiment resources on the Web. This article focuses on the problem of cross-lingual sentiment classification, which leverages only available English resources for Chinese sentiment classification. We first investigate several basic methods (including lexicon-based methods and corpus-based methods) for cross-lingual sentiment classification by simply leveraging machine translation services to eliminate the language gap, and then propose a bilingual co-training approach to make use of both the English view and the Chinese view based on additional unlabeled Chinese data. Experimental results on two test sets show the effectiveness of the proposed approach, which can outperform basic methods and transductive methods.
