Real-time SoC architecture and implementation for Variable Speech PDF based noise cancellation system

This paper discusses the architecture and implementation of system-on-chip (SoC) for noise cancellation system which uses Variable Speech PDF and MAP Estimation as noise cancelling algorithm. The hardware software co-design approach is used to achieve real-time performance while considering ease of implementation and design flexibility. The software module utilizes LEON SPARC-v8 and FPU co-prosessor as processing unit. The AMBA based Hanning Filter and FFT/IFFT are designed as processing accelerator module to increase system performance. The FFT/IFFT module uses custom Radix-22 Single Delay Feedback (R22SDF). In order to provide high data transfer rate between buffer and hardware accelerators, the DMA controller is also designed. The overall system implementation utilizes 18,500 logic elements and uses 21.87 kB of memory. Latency of the system is 0.69 ms so the system can be run in real-time. The system is implemented on FPGA Altera DE2-70 with both algorithms and the noise cancellation function has been verified.
A Web-based Bilingual Natural Language Interface to Database

Natural Language Interface to Database (NLIDB) enables end-user to communicate with the system in their native language. Many NLIDB systems have been developed in last few decades, these are mostly based on the Swing Technology. The paper proposes an NLIDB system namely WB-NLIDB (Web-based Bilingual Natural Language Interface to Database) that uses two natural languages Hindi and Punjabi. User can create query in both of the languages and receive the response in same natural language. For the formation of SQL query from natural language input, system uses the cases solver (Karak). The most important feature that has been introduced is the GUI of the system is web based using which the user enters the query in the Web browser and receives the response from the same browser. The developed system can run on any platform by simply connecting it with the local host. Also, WB-NLDDB provides various usability components for the end-users like inbuilt keywords for typing query, auto-complete text, storage of successful queries etc.
Regression-Based Bootstrapping of Web Service Reputation Measurement

In the literature, many solutions for measuring the reputation of web services have been proposed. These solutions help in building service recommendation systems. Nonetheless, there are still many challenges that need to be addressed in this context, such as the "cold start" problem, and the lack of estimation of the initial reputation values of newcomer web services. As reputation measurement depends on the previous reputation values, the lack of initial values can subvert the performance of the whole service recommendation system, making it vulnerable to different threats, like the Sybil attack. In this paper, we propose a new bootstrapping mechanism for evaluating the reputation of newcomer web services based on their initial Quality of Service (QoS) attributes, and their similarity with "long-standing" web services. Basically, the technique uses regression models for estimating the unknown reputation values of newcomer services from their known values of QoS attributes. The technique has been experimented on a large set of services, and its performance has been measured using some statistical metrics, such as the coefficient of determination (R2), Mean Absolute Error (MSE), and Percentage Error (PE).
Classifications of Emotion Expressed by Filipinos through Tweets

—This study attempted to classify the emotions of Filipinos expressed through their tweets. Based on these classifications, a personalized recommendation was generated to counter negative emotions. developed software had 70% accuracy on classifying the tweets. Thus, the emotions of Filipinos based on their tweets were classified effectively. Nonetheless, it was recommended that other Filipino dialects be incorporated to increase the effectiveness of the classifier. It was also suggested that the training data be enriched to capture more words describing emotions.
Reduced Losses in Die-Cast Machines With Insulated Rotors

This paper reports an investigation into the influence of interbar currents on the performance of die-cast cage induction machines. This work is based on an extensive set of experimental measurements using a series of specially made die-cast cage induction motors with bars insulated using alternate processes. Experimental measurements were undertaken separately by the industrial manufacturer and at the university laboratories, and these clearly demonstrate that increasing the insulation of the rotor cage inhibits the flow of interbar current and reduces the total motor losses and increases the motor efficiency as a consequence. The experimental measurements were further validated using an analytical interbar model. Further experimental measurements also demonstrate that insulating the rotor cage also modifies the stator torque in a counterintuitive fashion.
Self-esteem achievement through work and socio-demographic disparities in the labor market

We develop a model in which agents choose whether to achieve self-esteem through work. When they do, they develop an intrinsic motivtion to effort. Depending on the characteristics of the job to be filled, an employer may try, or not, to encourage this intrinsic motivation by an adequately designed contract. Although equally productive, assuming that agents from distinct socio-demographic groups differ in their propensity to achieve self-esteem through work, this may lead to unequal access to employment. We analyse the consequences of this model on labor market outcomes. The model can give an account of many important traits of socio-demographic disparities in the labor market (notably of vertical occupational segregation.
Immobilized Saccharomyces Cerevisiae as a potential aflatoxin decontaminating agent in pistachio nuts

ABSTRACT In this study, we investigated the binding ability of Saccharomayces cerevisiae to aflatoxin in pistachio nuts. The obtained results indicate that S. cerevisiae has an aflatoxin surface binding ability of 40% and 70% (with initial aflatoxin concentrations of 10 and 20 ppb) in the exponential phase. Acid treatments increase this ability to approximately 60% and 73% for the two concentrations of aflatoxin, respectively. Heat treatments also enhance surface binding to 55% and 75%, respectively. Binding appears to be a physical phenomenon that saturates within the first 2–3 hours of the process. The obtained results indicate that yeast immobilization for toxin reduction on aflatoxin-contaminated pistachios had no effect on qualitative characteristics, such as color, texture, and peroxide value. Yeast cells, viable or nonviable, are effective for aflatoxin binding, and this property could lead to a promising solution to aflatoxin contamination in high-risk foods.
Pleasurable music affects reinforcement learning according to the listener

Mounting evidence links the enjoyment of music to brain areas implicated in emotion and the dopaminergic reward system. In particular, dopamine release in the ventral striatum seems to play a major role in the rewarding aspect of music listening. Striatal dopamine also influences reinforcement learning, such that subjects with greater dopamine efficacy learn better to approach rewards while those with lesser dopamine efficacy learn better to avoid punishments. In this study, we explored the practical implications of musical pleasure through its ability to facilitate reinforcement learning via non-pharmacological dopamine elicitation. Subjects from a wide variety of musical backgrounds chose a pleasurable and a neutral piece of music from an experimenter-compiled database, and then listened to one or both of these pieces (according to pseudo-random group assignment) as they performed a reinforcement learning task dependent on dopamine transmission. We assessed musical backgrounds as well as typical listening patterns with the new Helsinki Inventory of Music and Affective Behaviors (HIMAB), and separately investigated behavior for the training and test phases of the learning task. Subjects with more musical experience trained better with neutral music and tested better with pleasurable music, while those with less musical experience exhibited the opposite effect. HIMAB results regarding listening behaviors and subjective music ratings indicate that these effects arose from different listening styles: namely, more affective listening in non-musicians and more analytical listening in musicians. In conclusion, musical pleasure was able to influence task performance, and the shape of this effect depended on group and individual factors. These findings have implications in affective neuroscience, neuroaesthetics, learning, and music therapy.

DNA methylation profiles of diverse Brachypodium distachyon align with underlying genetic diversity

DNA methylation, a common modification of genomic DNA, is known to influence the expression of transposable elements as well as some genes. Although commonly viewed as an epigenetic mark, evidence has shown that underlying genetic variation, such as transposable element polymorphisms, often associate with differential DNA methylation states. To investigate the role of DNA methylation variation, transposable element polymorphism, and genomic diversity, whole genome bisulfite sequencing was performed on genetically diverse lines of the model cereal Brachypodium distachyon. Although DNA methylation profiles are broadly similar, thousands of differentially methylated regions are observed between lines. An analysis of novel transposable element indel variation highlighted hundreds of new polymorphisms not seen in the reference sequence. DNA methylation and transposable element variation is correlated with the genome-wide amount of genetic variation present between samples. However, there was minimal evidence that novel transposon insertion or deletions are associated with nearby differential methylation. This study highlights the importance of genetic variation when assessing DNA methylation variation between samples and provides a valuable map of DNA methylation across diverse re-sequenced accessions of this model cereal species.

Molecular diversity and predictability of Vibrio parahaemolyticus along the Georgian coastal zone of the Black Sea

Vibrio parahaemolyticus is a leading cause of seafood-related gastroenteritis and is also an autochthonous member of marine and estuarine environments worldwide. One-hundred seventy strains of V. parahaemolyticus were isolated from water and plankton samples collected along the Georgian coast of the Black Sea during 28 months of sample collection. All isolated strains were tested for presence of tlh, trh, and tdh. A subset of strains were serotyped and tested for additional factors and markers of pandemicity. Twenty-six serotypes, five of which are clinically relevant, were identified. Although all 170 isolates were negative for tdh, trh, and the Kanagawa Phenomenon, 7 possessed the GS-PCR sequence and 27 the 850 bp sequence of V. parahaemolyticus pandemic strains. The V. parahaemolyticus population in the Black Sea was estimated to be genomically heterogeneous by rep-PCR and the serodiversity observed did not correlate with rep-PCR genomic diversity. Statistical modeling was used to predict presence of V. parahaemolyticus as a function of water temperature, with strongest concordance observed for Green Cape site samples (Percent of total variance = 70, P < 0.001). Results demonstrate a diverse population of V. parahaemolyticus in the Black Sea, some of which carry pandemic markers, with increased water temperature correlated to an increase in abundance of V. parahaemolyticus.

B‐cell very late antigen‐4 deficiency reduces leukocyte recruitment and susceptibility to central nervous system autoimmunity

Natalizumab, which binds very late antigen‐4 (VLA‐4), is a potent therapy for multiple sclerosis (MS). Studies have focused primarily upon its capacity to interfere with T‐cell migration into the central nervous system (CNS). B cells are important in MS pathogenesis and express high levels of VLA‐4. Here, we report that the selective inhibition of VLA‐4 expression on B cells impedes CNS accumulation of B cells, and recruitment of Th17 cells and macrophages, and reduces susceptibility to experimental autoimmune encephalomyelitis. These results underscore the importance of B‐cell VLA‐4 expression in the pathogenesis of CNS autoimmunity and provide insight regarding mechanisms that may contribute to the benefit of natalizumab in MS, as well as candidate therapeutics that selectively target B cells.

In this paper, we survey the most recent approaches for Web data representation, Web data accessing as well as for Web search engines.
Voluntary Disclosure Bringing about Information "Lemon" or "Transparent?": From Information Reliability Perspective

This paper investigates the relationship of voluntary disclosure and information quality. A broad sample of 4551 listed Chinese firms is choused excluding financial industries from 2005 to 2008. Considering endogenous problem, we use OLS model and a model of simultaneous equations (2SLS method) to explore the relationship, respectively. Our results indicate that there is a typical endogenous problem between voluntary disclosure and information quality; the higher the reliability of company information, the higher level of voluntary disclosure of information, thus, voluntary disclosure level reflects information quality to a certain, and provides investors with a simple tool for identifying listed company information quality; however, the level of voluntary disclosure has negative effects on information quality, as shows that some companies with higher reliability information may make use of the trust of their investors. Further, we find that, the level of voluntary disclosure has far less influence on information quality than the opposite impact according to coefficient. Therefore, voluntary disclosure makes China's capital market more transparent, as a whole. But, It is not neglected the compact of voluntary disclosure on information quality, yet.

Neonatal Neuronal Circuitry Shows Hyperexcitable Disturbance in a Mouse Model of the Adult-Onset Neurodegenerative Disease Amyotrophic Lateral Sclerosis

Distinguishing the primary from secondary effects and compensatory mechanisms is of crucial importance in understanding adult-onset neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). Transgenic mice that overexpress the G93A mutation of the human Cu-Zn superoxide dismutase 1 gene (hSOD1G93A mice) are a commonly used animal model of ALS. Whole-cell patch-clamp recordings from neurons in acute slice preparations from neonatal wild-type and hSOD1G93A mice were made to characterize functional changes in neuronal activity. Hypoglossal motoneurons (HMs) in postnatal day 4 (P4)–P10 hSOD1G93A mice displayed hyperexcitability, increased persistent Na+ current (PCNa), and enhanced frequency of spontaneous excitatory and inhibitory transmission, compared with wild-type mice. These functional changes in neuronal activity are the earliest yet reported for the hSOD1G93A mouse, and are present 2–3 months before motoneuron degeneration and clinical symptoms appear in these mice. Changes in neuronal activity were not restricted to motoneurons: superior colliculus interneurons also displayed hyperexcitability and synaptic changes (P10–P12). Furthermore, in vivo viral-mediated GFP (green fluorescent protein) overexpression in hSOD1G93A HMs revealed precocious dendritic remodeling, and behavioral assays revealed transient neonatal neuromotor deficits compared with controls. These findings underscore the widespread and early onset of abnormal neural activity in this mouse model of the adult neurodegenerative disease ALS, and suggest that suppression of PCNa and hyperexcitability early in life might be one way to mitigate or prevent cell death in the adult CNS.
Controlling Iteration in Product Development Processes

Iteration is a dominant though unwelcome feature of product development. Controlling this iteration can reduce the time needed to complete product development projects. Management must decide how long each project should spend in a design stage before it undergoes a design review (or test). This paper presents a model of iteration that can be used to make this decision. The paper considers the singleproject case and two scenarios in which multiple projects require a common reviewer. These results give some insight into how managers should control iteration to improve their product development processes.
Efficient Management of Short-Lived Data

Motivated by the increasing prominence of loosely-coupled systems, such as mobile and sensor networks, which are characterised by intermittent connectivity and volatile data, we study the tagging of data with so-called expiration times. More specifically, when data are inserted into a database, they may be tagged with time values indicating when they expire, i.e., when they are regarded as stale or invalid and thus are no longer considered part of the database. In a number of applications, expiration times are known and can be assigned at insertion time. We present data structures and algorithms for online management of data tagged with expiration times. The algorithms are based on fully functional, persistent treaps, which are a combination of binary search trees with respect to a primary attribute and heaps with respect to a secondary attribute. The primary attribute implements primary keys, and the secondary attribute stores expiration times in a minimum heap, thus keeping a priority queue of tuples to expire. A detailed and comprehensive experimental study demonstrates the well-behavedness and scalability of the approach as well as its efficiency with respect to a number of competitors.

Self-Diplexed Patch Antennas Based on Metamaterials for Active RFID Systems

This paper presents a full duplex active RF identification system with arbitrary values for any of the two frequencies in the different radio links. First, the antennas proposed in this paper are based on linearly polarized self-diplexed patch antennas working in a full-duplex way at 2.45 GHz for the reader-transponder (or tag) link and at a lower variable frequency (1.7 GHz) for the transponder-reader link reducing the propagation losses for the most critical link. Secondly, in order to reduce the multipath losses, antennas with circular polarizations for the reader and linear polarization for the transponder have been designed for the corresponding radio links. Patch antennas partially filled with metamaterial cells have offered the possibility of achieving multifrequency performance with two dipolar radiation modes, one due to the patch and the other to the metamaterial cells. This fact makes it possible to obtain high isolation levels between different ports. In addition, the inclusion of coupled or slot lines to feed the antenna has increased this isolation level. Finally, the diplexing level has been increased by including some filtering lines with metamaterial particles at the input of the feeding line. This approach avoids using an external filter or diplexer.
An Improvement on a Non-deterministic One-to-n Substitution Scheme in Outsourcing Association Rule Mining
