Nonverbal learning disabilities.

Introduction There is no typical picture of a child with a learning disability. Learning-disabled children show a range of learning styles and present diverse areas of strengths and weaknesses. The term “learning disability,” which originated in the early 1960s, was used to describe children with normal intelligence who were not achieving adequately in the usual educational settings. Since that time there have been a number of attempts to identify subtypes of learning disabilities for the purpose of establishing appropriate intervention strategies. The subtypes were initially categorized as a deficiency in verbal acquisition or academic achievement. Researchers subsequently began to describe another subset of children who didn't fit into the established categories. Their deficits were neither verbal nor academic in the usual sense; rather they were lacking in social perception. Although they possessed well developed verbal skills, these children were unable to comprehend the significance of many aspects of their environment. They had difficulty interpreting the meaning of others’ actions, gestures and facial expressions. In short, these children had trouble "reading between the lines. " This constellation of strengths and weaknesses is classified as a Nonverbal Learning Disability.
Anti-Ulcerogenic Effect of Methanolic Extracts from Enicosanthellum pulchrum (King) Heusden against Ethanol-Induced Acute Gastric Lesion in Animal Models

A natural source of medicine, Enicosanthellum pulchrum is a tropical plant which belongs to the family Annonaceae. In this study, methanol extract from the leaves and stems of this species was evaluated for its gastroprotective potential against mucosal lesions induced by ethanol in rats. Seven groups of rats were assigned, groups 1 and 2 were given Tween 20 (10% v/v) orally. Group 3 was administered omeprazole 20 mg/kg (10% Tween 20) whilst the remaining groups received the leaf and stem extracts at doses of 150 and 300 mg/kg, respectively. After an additional hour, the rats in groups 2–7 received ethanol (95% v/v; 8 mL/kg) orally while group 1 received Tween 20 (10% v/v) instead. Rats were sacrificed after 1 h and their stomachs subjected to further studies. Macroscopically and histologically, group 2 rats showed extremely severe disruption of the gastric mucosa compared to rats pre-treated with the E. pulchrum extracts based on the ulcer index, where remarkable protection was noticed. Meanwhile, a significant percentage of inhibition was shown with the stem extract at 62% (150 mg/kg) and 65% (300 mg/kg), whilst the percentage with the leaf extract at doses of 150 and 300 mg/kg was 63% and 75%, respectively. An increase in mucus content, nitric oxide, glutathione, prostaglandin E2, superoxide dismutase, protein and catalase, and a decrease in malondialdehyde level compared to group 2 were also obtained. Furthermore, immunohistochemical staining of groups 4–7 exhibited down-regulation of Bax and up-regulation of Hsp70 proteins. The methanol extract from the leaves and the stems showed notable gastroprotective potential against ethanol.
A case–control study of tyrosine phosphatase (PTPN22) confirms the lack of association with Crohn's disease

In Crohn's disease (CD), the whole gastrointestinal tract can be affected by discontinuous and transmural inflammation. The terminal ileum and colon are especially prone to inflammation that comprises granulomata and later intestinal and perianal fistulas. Genome‐wide linkage and epidemiological studies established genetic predisposition factors to CD.
Bayesian Network for Predicting Students' Final Grade Using e-Book Logs in University Education

This paper describes visualization and analysis methods using educational big data collected by research project at Kyushu University in Japan. The project uses an e-book system called BookLooper, Moodle, and Mahara. Logs for this analytics were collected from 99 first-year students in an information science course at Kyushu University. The number of logs are collected approximately 330,000, and this paper visualize and analyze the collected logs. The purpose of this study is to predict students' final grade and to profile visualization and analysis results. The prediction of this study shows that it leads to discoveries of students who fail to make the grade.
Subset source coding

Emerging applications including semantic information processing impose priorities on the possible realizations of information sources, so that not all source sequences are important. This paper proposes an initial framework for optimal lossless compression of subsets of the output of a discrete memoryless source (DMS). It turns out that, the optimal source code may not index the conventional source-typical sequences, but rather index certain subset-typical sequences determined by the source statistics as well as the subset structure. Building upon an achievability and a strong converse, an analytic expression is given, based on the Shannon entropy, relative entropy, and subset entropy, which identifies such subset-typical sequences for a broad class of subsets of a DMS. Interestingly, one often achieves a gain in the fundamental limit, in that the optimal compression rate for the subset can be strictly smaller than the source entropy, although this is not always the case.

Mitochondrial Genome of the Stonefly Kamimuria wangi (Plecoptera: Perlidae) and Phylogenetic Position of Plecoptera Based on Mitogenomes

This study determined the mitochondrial genome sequence of the stonefly, Kamimuria wangi. In order to investigate the relatedness of stonefly to other members of Neoptera, a phylogenetic analysis was undertaken based on 13 protein-coding genes of mitochondrial genomes in 13 representative insects. The mitochondrial genome of the stonefly is a circular molecule consisting of 16,179 nucleotides and contains the 37 genes typically found in other insects. A 10-bp poly-T stretch was observed in the A+T-rich region of the K. wangi mitochondrial genome. Downstream of the poly-T stretch, two regions were located with potential ability to form stem-loop structures; these were designated stem-loop 1 (positions 15848–15651) and stem-loop 2 (15965–15998). The arrangement of genes and nucleotide composition of the K. wangi mitogenome are similar to those in Pteronarcys princeps, suggesting a conserved genome evolution within the Plecoptera. Phylogenetic analysis using maximum likelihood and Bayesian inference of 13 protein-coding genes supported a novel relationship between the Plecoptera and Ephemeroptera. The results contradict the existence of a monophyletic Plectoptera and Plecoptera as sister taxa to Embiidina, and thus requires further analyses with additional mitogenome sampling at the base of the Neoptera.
Quantum programming made easy

We present IQu, namely a quantum programming language that extends Reynold's Idealized Algol, the paradigmatic core of Algol-like languages. IQu combines imperative programming with high-order features, mediated by a simple type theory. IQu mildly merges its quantum features with the classical programming style that we can experiment through Idealized Algol, the aim being to ease a transition towards the quantum programming world. The proposed extension is done along two main directions. First, IQu makes the access to quantum co-processors by means of quantum stores. Second, IQu includes some support for the direct manipulation of quantum circuits, in accordance with recent trends in the development of quantum programming languages. Finally, we show that IQu is quite effective in expressing well-known quantum algorithms.
Fast Low-Dose Reconstruction From Truncated Data in Dental CT

To reduce the radiation dose in dental computed tomography (CT), backprojection-filtration (BPF) algorithm is the preferred choice as it can reconstruct images from truncated data within limited scanning angle, thereby reducing radiation dose and avoiding irradiation to the brain. However, the integral interval of backprojection is variable for every PI-line which causes the calculation efficiency and parallel performance to be low. In this paper, the tent BPF method (T-BPF) was developed, which was performed by firstly rearranging the cone-beam data to tent-like parallel-beam data, and then applying the proposed BPF-type algorithm to reconstruct images from the rearranged data. T-BPF turns the variable integral interval of backprojection into fixed integral interval, which means the reconstruction efficiency and the parallel performance of T-BPF are improvements over those of the original BPF algorithm. The experiments of numerical simulation and real data reconstruction show that the reconstruction efficiency of T-BPF is faster than the original BPF algorithm and the FDK algorithm in the case of comparable reconstruction quality. The results demonstrate that the proposed T-BPF is good at achieving fast low-dose reconstruction from truncated projection data in dental CT.
Low-complexity gain and phase I/Q mismatch compensation using orthogonal pilot sequences

In up-to-date receiver architectures the gain and phase mismatch between the I and Q signal paths may degrade significantly the overall link performance. An alternative cost effective solution to expensive analog components with small tolerances, which make the I/Q mismatch effect negligible, consists in estimating and compensating it through appropriate digital signal processing techniques. In this paper we derive a novel low-complexity data-aided scheme for jointly estimating the carrier phase offset, the I/Q phase mismatch, and the gain of the I and Q branches following the maximum likelihood criterion and adopting as training symbols an orthogonal sequence. The performance analysis proves that the proposed estimator is low-complexity, asymptotically efficient and capable of compensating considerable I/Q mismatch values in the demanding scenario of both uncoded and coded multi-level QAM transmissions.
Basins of Convergence of Equilibrium Points in the Generalized Hill Problem

The Newton-Raphson basins of attraction, associated with the libration points (attractors), are revealed in the generalized Hill problem. The parametric variation of the position and the linear stability of the equilibrium points is determined, when the value of the perturbation parameter $\epsilon$ varies. The multivariate Newton-Raphson iterative scheme is used to determine the attracting domains on several types of two-dimensional planes. A systematic and thorough numerical investigation is performed in order to demonstrate the influence of the perturbation parameter on the geometry as well as of the basin entropy of the basins of convergence. The correlations between the basins of attraction and the corresponding required number of iterations are also illustrated and discussed. Our numerical analysis strongly indicates that the evolution of the attracting regions in this dynamical system is an extremely complicated yet very interesting issue.
Cutibacterium acnes is less commonly identified by next-generation sequencing than culture in primary shoulder surgery

Introduction High rates of positive Cutibacterium acnes cultures from primary shoulder surgery make positive cultures in the revision surgery setting difficult to interpret. Our goal was to determine concordance between culture and next-generation sequencing techniques for identification of C. acnes from primary shoulder surgery. Methods Patients undergoing shoulder arthroscopy for rotator cuff tear or primary anatomic shoulder arthroplasty for osteoarthritis were prospectively enrolled. Specimens were sent for culture (aerobic and anaerobic) and next-generation sequencing. For next-generation sequencing, the entire microbial DNA was sequenced in order to identify pathogens within the sample. Results Our cohort consisted of 90 patients (45 patients in the osteoarthritis group and 45 patients in the rotator cuff tear group). At least one sample was positive for C. acnes in 18 (20%) cases by culture and in 14 (15.6%) cases by next-generation sequencing (p = 0.559). Four (22.2%) of the 18 cases with positive C. acnes cultures also had C. acnes identified by next-generation sequencing (kappa = 0.238). There was no difference in C. acnes identification rates between osteoarthritis and rotator cuff tear groups. Conclusions There was limited concordance between culture and next-generation sequencing for C. acnes identification. Further studies are needed to determine the potential for next-generation sequencing as a diagnostic tool.
Molecular Discrimination of Sheep Bovine Spongiform Encephalopathy from Scrapie

Sheep CH1641-like transmissible spongiform encephalopathy isolates have shown molecular similarities to bovine spongiform encephalopathy (BSE) isolates. We report that the prion protein PrPSc from sheep BSE is extremely resistant to denaturation. This feature, combined with the N-terminal PrPSc cleavage, allowed differentiation of classical scrapie, including CH1641-like, from natural goat BSE and experimental sheep BSE.
Race analysis for SystemC using model checking

SystemC is a system-level modeling language that offers a wide range of features to describe concurrent systems at different levels of abstraction. The SystemC standard permits simulators to implement a deterministic scheduling policy, which often hides concurrency-related design flaws. We present a novel compiler for SystemC that integrates a formal and scalable race analysis. This analysis combines both classic static analysis and model checking techniques. The outcome of the analysis is not only valuable to diagnose the effect of race conditions, but can also be used to improve simulation performance dramatically. Our compiler produces a simulator that uses the race analysis information at runtime to perform partial-order reduction, thereby eliminating context switches that do not affect the result of the simulation. Experimental results show simulation speedups of one order of magnitude and better.
Influence of doxazosin on biosynthesis of S100A6 and atrial natriuretic factor peptides in the heart of spontaneously hypertensive rats

Hypertension frequently results in severe complications in cardiovascular system and histopathological changes in the heart. To better understand the cellular processes and signaling pathways responsible for the proper functioning of the heart, we decided to check whether doxazosin affects the density of structures containing S100A6 and atrial natriuretic factor in the heart of spontaneously hypertensive rats. The aim of this study is to find differences in the density of the structures containing S100A6 and atrial natriuretic factor in the heart of spontaneously hypertensive rats treated with doxazosin compared to untreated animals. Fragments of heart were collected from five spontaneously hypertensive rats and five spontaneously hypertensive rats receiving doxazosin for six weeks (dose 0.1 mg per 1 kg of body weight). On the paraffin sections S100A6 and atrial natriuretic factor peptides were localized in the heart using immunohistochemistry. Positive immunohistochemical reaction for S100A6 was observed in atrial and ventricular cardiomyocytes and in the coronary vasculature. In the heart of hypertensive rats treated with doxazosin the S100A6 immunoreactivity was significantly lower compared to untreated animals. Immunodetection of atrial natriuretic factor in the heart of rats confirmed presence of peptide in atrial myocardium. Delicate atrial natriuretic factor-immunoreactivity was observed also in few ventricular cardiomyocytes. The atrial natriuretic factor-immunosignal was significantly weaker in hearts of hypertensive rats receiving doxazosin compared to spontaneously hypertensive rats untreated. Since we found that doxazosin reduces the levels of S100A6 and atrial natriuretic factor peptides in the heart of spontaneously hypertensive rats, it can be assumed that cardiovascular disorders that occur in hypertension may be associated with disturbances of cellular processes and signaling pathways.
Providing Seamless Communications in Mobile Wireless Networks

This paper presents a technique to provide seamless communications in mobile wir eless networks. The goal of seamless communication is to provide disruption fre e service to a mobile user. A disruption in service could occur due to active h andoffs (handoffs during an active connections). Existing protocols either prov ide total guarantee for disruption free service incurring heavy network bandwidt h usage (multicast based approach), or do not provide any guarantee for disrupti on free service (forwarding approach). There are many user applications that do not require a "total" guarantee for disruption free service but would also not tolerate very frequent disruptions. This paper proposes a novel staggered multi cast approach which provides a probabilistic guarantee for disruption free servi ce. The main advantage of the staggered multicast approach is that it exploits the performance guarantees provided by the multicast approach and aides the much required savings in the static network bandwidth. The problem of guaranteeing disruption free service to mobile users becomes more acute when the static backb one network does not use any packet numbering or does not use any packet numberi ng or does not provide retransmissions. Asynchronous Transfer Mode networks, th e future of B-ISDN, display these properties. To make our study complete, we present a possible implementation of our scheme for wireless ATM networks.
Hemagglutinin residues of recent human A(H3N2) influenza viruses that contribute to the inability to agglutinate chicken erythrocytes.

To identify the molecular determinants contributing to the inability of recent human influenza A(H3N2) viruses to agglutinate chicken erythrocytes, phenotypic revertants were selected upon passage in eggs or MDCK cells. The Leu194Ile or Val226Ile substitutions were detected in their hemagglutinin (HA) sequence concomitantly with the phenotypic reversion. Remarkably, as little as 3.5% of variants bearing a Val226Ile substitution was found to confer the ability to agglutinate chicken erythrocytes to the virus population. Hemadsorption assays following transient expression of mutated HA proteins showed that the successive Gln226 --> Leu --> Ile --> Val changes observed on natural isolates resulted in a progressive loss of the ability of the HA to bind chicken erythrocytes. The Val226Ile change maintained the preference of the HA for SAalpha2,6Gal over SAalpha2,3Gal and enhanced binding of the HA to alpha2,6Gal receptors present on chicken erythrocytes. In contrast, simultaneous Ser193Arg and Leu194Ile substitutions that were found to confer the ability to agglutinate sheep erythrocytes increased the affinity of the HA for SAalpha2,3Gal.
Proteomic analysis of a 120 kDa protein complex in cyst fluid of Taenia solium metacestode and preliminary evaluation of its value for the serodiagnosis of neurocysticercosis

Cyst fluid (CF) of Taenia solium metacestode (TsM) is an important source of serodiagnostic antigens. We have investigated the molecular characteristics of the 120 kDa protein complex in TsM CF purified by fast performance liquid chromatography. The structure of the purified protein was characterized by a variety of proteomic analyses. The protein was found to consist of 2 major components of 42–46 and 22–28 kDa, and shared 3 subunits of 14, 16 and 18 kDa. The 42–46 kDa component was determined to contain 3 additional subunits of 22, 28 and 38 kDa. These 6 subunits were shown to originate from either the 14 or 18 kDa precursor. We assessed the antibody reactivity of the native protein, its individual subunits and the recombinant 14 and 18 kDa proteins, and found that the 120 kDa protein, particularly 14 and 18 kDa subunits revealed high reliability for differentiation of active and mixed stage NC from chronic NC. The subunits of the 120 kDa protein complex identified herein represent some of the low-molecular weight glycoproteins which have been described in several previous studies. Recognizing and understanding the structural and immunological relationship of these proteins will facilitate the development of new serodiagnostic assays.
A novel web recommender system considering users' need evolution

The recommender systems' task is to predict items in which a user might like in future. Typically they do it in two stages. One, offline stage, that extracts patterns from mining users' historical behavior, and another, online stage predicts items by matching the active requests with the patterns; but without considering other interests of the active user. In general, web users' navigations contain gradual evolution of their needs. We conducted an approach that addresses the evolving nature of users' needs and interests in making recommendations. Since users' behaviors are not stable and their interest changes with time, our approach is based on interest-drifting. One of the main shortcomings of interest-drifting based approaches is that they assume different users have the similar interest changes over time and do not consider this important factor that the trend of interest changes for users is different. This paper attempts to tackle this problem, too. Up to now there has not been any study to tackle these problems. We evaluate our proposed methodology on EachMovie dataset. Results show a better performance than existing approaches.
Source-channel matching space-time diversity for multimedia communications

A source-channel matching space-time diversity technique is presented for reliable delivery of layer coded multimedia services through wireless channels. The transmission system is transformed to multiple channel layers associated with different diversity gain. Similarly to the parallel transmission proposed for ADSL, we develop a parallel transmission scheme to match the source layers to the channel layers. Power control further alters the error performance of each channel layer to achieve optimal performance.

1 Abstract—This paper considers the problem of interpolating signals defined on graphs. A major presumption considered by many previous approaches to this problem has been low-pass/band-limitedness of the underlying graph signal. However, inspired by the findings on sparse signal reconstruction, we consider the graph signal to be rather sparse/compressible in the Graph Fourier Transform (GFT) domain and propose the Iterative Method with Adaptive Thresholding for Graph Interpolation (IMATGI) algorithm for sparsity promoting interpolation of the underlying graph signal. We provide a formal convergence proof for the proposed algorithm. We also demonstrate efficient performance of the proposed IMATGI algorithm in reconstructing randomly generated sparse graph signals. Finally, we consider the widely desirable application of recommendation systems and show by simulations that IMATGI outperforms state-of-the-art algorithms on the benchmark datasets in this application.
