The January Anomaly: Effects of Low Share Price

The device is an insulating nipple which is inserted into a pipeline. It comprises an inner, tubular, glass-reinforced, epoxy plastic liner, a steel nipple surrounding the liner and having a circumferential gap cut through its wall, and a steel jacket sleeve surrounding the nipple and extending between its threaded ends. Epoxy plastic is used to fill the annular spaces, between the liner and nipple and nipple and sleeve, as well as the gap. The insulated gap interrupts the movement of ground currents along the pipeline, and the liner functions to prevent current skip across the gap through the pipeline fluid. The device is capable of being used at high pressures, in the order of 1,500 p.s. i. or greater.
Acute and subacute (28-Day) toxicity studies of ionic liquid, didecyldimethyl ammonium acesulfamate, in rats

The aim of this study was to investigate acute and subacute oral toxicity of an ionic liquid, didecyldimethylammonium acesulfamate [DDA][Ace], in rats. The compound tested was classified to the fourth toxicity class with a fixed LD50 cut-off value of 500 mg/kg. Organ pathology induced by [DDA][Ace] in acute experiments included exfoliation of the surface layer of the digestive tract and alveolar septa in lung parenchyma. In a subacute experiment, rats were administered 10, 50, and 100 mg/kg/day [DDA][Ace] for 28 days. Reduced body weight gain and reduced food consumption was observed in mid- and high-dose rats. Statistically significant hematology changes were found mostly in high-dose groups of both sexes: increases in hematocrit, mean corpuscular volume, and mean platelet volume. Statistically significant changes in clinical chemistry parameters included increases in the GGT, SDH, and LDH activity and bilirubin concentration, and decreases in triglycerides, glucose, and inorganic phosphorus concentration. No treatment-related microscopic changes were observed. Under the conditions of this study, the lowest-observed-adverse-effect level of [DDA][Ace] was considered to be 10 mg/kg/day.
Design and evaluation of a tool for reminiscence of life-logged data

In this paper we present a design, development and evaluation of a tool to facilitate the reminiscence of life-logged data intended for persons with dementia. Using off-the-shelf technologies such as a smartphone it is possible to effectively record and log a person's daily activates such as places visited and persons interacted with. We developed a reminiscence tool that visualizes life-logging data. The system was evaluated with six healthy participants aged between 24-46 years of age. They recorded approximately 2.5 hours of life-logging data that was later loaded into the developed tool. During the subsequent evaluation, the participant's gaze was tracked using eye-tracking hardware. Results show that the tool was easy to use and navigate through, facilitating the objective identification of events that may be useful for reminiscence.
Application of formal methods for validation and verification of embedded system communication protocol

There are plethora of control based embedded systems installed in domestic electronic systems. The correct working of these embedded systems is important for successful functionality of the overall system. Most of these embedded system communicate using some communication protocol. Thus the protocol must be error free for successful working of overall system. This paper explains a scenario in which a communication problem occurred between two embedded components. By taking the problem in to account, the paper provides formal verification techniques to solve this communication issue. Buffers are used to read and send data for inter components communication. In some situations, when data is read from the buffers without flushing them, usually junk data is induced along with information(packets) which causes the system to be in indeterminate state. This situation might result to be a complete system failure for such critical real time systems. This paper claims that such communication problems can be easily detected by developing formal models of the communication protocol and applying formal verification tests to confirm a certain property holds or not. In case of a failure, the model checker automatically generates a trace explaining how and why the property has failed. We later confirmed our results by manually generating the scenario generated by model checker in actual code. This has been an efficient bug hunting technique and we aim to test more communication protocols in future using this technique using formal methods which is a very powerful technique for validation and verification of software system problems.
Distributed energy resources with home energy management in smart grid

In this paper, an optimal real-time home energy management to regulate the residential appliances is proposed considering renewable energy resources included in the grid. The appliances can be classified into different groups, where the time shiftable appliances are participated in the scheme to schedule their operational period via the price incentive. An improved binary swarm optimization algorithm is introduced to optimize the usage of household appliances. The parameter settings in the particle location of the algorithm are improved to increase the global searching capability and convergence speed. Besides, the renewable energy resources such as PV panel and wind turbine output are discussed. Simulation experiments are performed to prove the efficacy of the proposed algorithm.
Journal of Theoretical and Applied Information Technology Information Retrievals Tries Tree Vs Inverted File Word Method for Arabic Language

One of the key challenges of managing very huge volumes of data in scalable Information retrieval systems is providing fast access through keyword searches. The major data structure in the information retrieval system is an inverted file, which records the positions of each term in the documents. When the information set substantially grows, the number of terms and documents are significantly increased as well as the size of the inverted files. In this research we implement to techniques of inverted file-posting list and Tries trees-on Arabic Language, then we will try to state the optimum technique to store the vocabulary according to the speed of retrieving queries from the collection of documents. 1. INTRODUCTION the information retrieval its Aims to retrieve information stored large amount of data access and contribute to it, as fast as possible to contain information on more than one form of the visual and textual or audio information retrieval system is a system to store information to be available for future use. Most actual information system, systems store and enable the retrieval of only textual. The user can to retrieve the information through the query, where the information retrieval system to retrieve all theinformation that "satisfy" the query, which is in contrast to database systems. Information retrieval not return a definite answer, but produce a ranking of documents that seem tocontain information relevant to the query given to the system, queries and documents in natural language based system, information retrieval on the division of each word. This process is called indexing and During indexing stops words ("the", "but", "and", etc.) are discarded, and suffixes are removed, where the words that the system remained divided into two terms to be queries and documents[7]. Several different types of index have been expressed. The most well-organized index structure for text query evaluation is the Inverted File:a collection of lists, one per term, recording the identifiers of the documents containing that term[20]. An elective structure for storing vocabularies is a B+ tree. The high branching factor typical of these trees means that the internal nodes are only a small percentage of the total vocabulary size. For example, suppose that in a B+-tree leaves contain pointers to inverted lists that the vocabulary of some database contains 1,000,000 distinct 12-byte terms, and that the disk being used operates with 8-kilobyte blocks and 4-byte pointers. Then at most 64 kilobytes is required for …
Evolving Insights on Metabolism, Autophagy, and Epigenetics in Liver Myofibroblasts

Liver myofibroblasts (MFB) are crucial mediators of extracellular matrix (ECM) deposition in liver fibrosis. They arise mainly from hepatic stellate cells (HSCs) upon a process termed “activation. ” To a lesser extent, and depending on the cause of liver damage, portal fibroblasts, mesothelial cells, and fibrocytes may also contribute to the MFB population. Targeting MFB to reduce liver fibrosis is currently an area of intense research. Unfortunately, a clog in the wheel of antifibrotic therapies is the fact that although MFB are known to mediate scar formation, and participate in liver inflammatory response, many of their molecular portraits are currently unknown. In this review, we discuss recent understanding of MFB in health and diseases, focusing specifically on three evolving research fields: metabolism, autophagy, and epigenetics. We have emphasized on therapeutic prospects where applicable and mentioned techniques for use in MFB studies. Subsequently, we highlighted uncharted territories in MFB research to help direct future efforts aimed at bridging gaps in current knowledge.
Role of the human transferrin receptor cytoplasmic domain in endocytosis: localization of a specific signal sequence for internalization

Wild-type and mutant human transferrin receptors have been expressed in chicken embryo fibroblasts using a helper-independent retroviral vector. The internalization of mutant human transferrin receptors, in which all but four of the 61 amino acids of the cytoplasmic domain had been deleted, was greatly impaired. However, when expressed at high levels, such "tailless" mutant receptors could provide chicken embryo fibroblasts with sufficient iron from diferric human transferrin to support a normal rate of growth. As the rate of recycling of the mutant receptors was not significantly different from wild-type receptors, an estimate of relative internalization rates could be obtained from the distribution of receptors inside the cell and on the cell surface under steady-state conditions. This analysis and the results of iron uptake studies both indicate that the efficiency of internalization of tailless mutant receptors is approximately 10% that of wild-type receptors. Further studies of a series of mutant receptors with different regions of the cytoplasmic domain deleted suggested that residues within a 10-amino acid region (amino acids 19-28) of the human transferrin receptor cytoplasmic domain are required for efficient endocytosis. Insertion of this region into the cytoplasmic domain of the tailless mutant receptors restored high efficiency endocytosis. The only tyrosine residue (Tyr 20) in the cytoplasmic domain of the human transferrin receptor is found within this 10-amino acid region. A mutant receptor containing glycine instead of tyrosine at position 20 was estimated to be approximately 20% as active as the wild-type receptor. We conclude that the cytoplasmic domain of the transferrin receptor contains a specific signal sequence located within amino acid residues 19-28 that determines high efficiency endocytosis. Further, Tyr 20 is an important element of that sequence.
Neural consequences of religious belief on self-referential processing

Abstract Christianity strongly encourages its believers to surrender to God and to judge the self from God's perspective. We used functional MRI to assess whether this religious belief is associated with neural correlates of self-referential processing distinct from that of non-religious people. Non-religious and Christian participants were scanned while performing tasks of personal-trait judgments regarding the self or public persons. We found that, while self-judgment was linked to better memory of traits related to the self than to others, self-referential processing induced increased activity in the ventral medial prefrontal cortex (MPFC) for non-religious participants but in the dorsal MPFC for Christian participants. In addition, the dorsal MPFC activity was positively correlated with the rating scores of the importance of Jesus’ judgment in subjective evaluation of a person's personality. Because the ventral and dorsal MPFC are respectively engaged in representation of stimulus self-relevance and evaluation of self-referential stimuli, our findings suggest that Christian beliefs result in weakened neural coding of stimulus self-relatedness but enhanced neural activity underlying evaluative processes applied to self-referential stimuli.
Do We Expect Too Much of Bilingual Teachers? Bilingual Teaching in Developing Countries

Given the unique character of bilingual students and the programmes that support them, primary bilingual teaching is a challenging job in any country. However, bilingual teachers in developing contexts are especially challenged; they are often undertrained and underpaid, and must function in under-resourced schools with undernourished students. Meanwhile, they are expected to teach beginning literacy in the mother tongue, communicative language skills in the exogenous (ex-colonial) language, and curricular content in both, requiring that they be as bilingual and biliterate as possible. In addition, they must bridge the linguistic and cultural gap between home and school, become respected members of the community, and manage any opposition to educational use of the mother tongue. Using examples from Bolivia and Mozambique, developing countries from two different continents both of which are in the process of implementing bilingual programmes, this paper discusses the training needs of bilingual teachers as well as the built-in strengths they possess on which their training should capitalise. The outcomes of this discussion are a set of suggestions for alternative teaching models that could optimise teacher effectiveness in such contexts, as well as a template for a training curriculum that builds on teachers' strengths while addressing their weaknesses.
A Method for Solving a Bipartite-Graph Clustering Problem with Sequence Optimization

In this paper, we propose the solving method of bipartite-graph clustering problem (BCP) by transforming from BCP into traveling salesman problem (TSP). The analysis of information in web is an important guide to understand how to organize the wisdom of mankind. Especially, to divide from related information into communities of a suitable number is useful to the extraction of valuable information. One of the methods for extracting the community is using bipartite graph. BCP is equal to TSP with some concentrated cities, in the point of classifying the similar vertexes into each cluster. In order to solve TSP by smaller computational cost, we adopt the local clustering organization (LCO) method from many proposed solution for TSP. LCO has been proven to be possible to perform the high-speed computation for large-scale TSP. As the result of some computational experiments, we verified that our proposed method is possible to decide an optimum threshold of cost by observing the distribution.
Species richness enhances both algal biomass and rates of oxygen production in aquatic microcosms

Accelerating rates of species extinction have generated much recent interest in understanding how biodiversity affects the functioning of ecosystems. Experiments to date have shown communities composed of fewer species generally capture a smaller fraction of available resources, and achieve lower standing stock biomass than more diverse communities. However, it is uncertain how changes in biodiversity and the resulting alterations in biomass affect the rates of important ecological processes like primary production, which regulates fluxes of CO 2 and O 2 between the biotic and abiotic components of the environment. Here we show that species richness influences not only the standing stock biomass of primary producers, but also rates of gross primary production measured by changes in O 2 concentrations in aquatic systems. We manipulated the richness of five widespread species of algae in laboratory microcosms and then quantified how richness impacts algal biomass, rates of gross primary production (GPP), and the ratio of production to respiration. Algal biomass increased by a factor of 1.82 for each level of species richness, and GPP by a factor of 1.20, for each additional species. Production to respiration ratios increased about 10% for each additional species, indicating that systems with more species were increasingly autotrophic - that is, they produced more O 2 than they consumed, and accumulated CO 2 faster than they released it. These trends were driven by two highly productive species that became co-dominant in species rich polycultures at the expense of other taxa. Our experiment suggests that changes in biodiversity may influence not only the rates at which O 2 and CO 2 are produced and released in ecosystems, but also the total amount of carbon that is sequestered and stored as biomass.
Brand Familiarity and Advertising Repetition Effects

A crucial communication task for unknown brands is to build the knowledge in consumers' minds necessary to become established. However, communication effectiveness may depend on prior familiarity of the advertised brand. The findings of two experiments using television ads and computer Internet ads revealed that brand familiarity influenced repetition effectiveness. In particular, repetition of advertising attributed to an unfamiliar brand showed decreased effectiveness; when the same advertising was attributed to a known, familiar brand, repetition wearout was postponed. Negative thoughts about tactic inappropriateness were seen to arise with repetition, particularly for an ad for an unfamiliar brand, driving, in part, the decreases in repetition effectiveness.

“Accessibility, Usability & Embeddedness”: Social Capital and the Status Attainment Process for Men in the Netherlands

This study addresses the status attainment process and the associated mobility between generations for men in Dutch society in 2000. It does so by integrating the social resources theory (Lai et al., 1998) with the classic status attainment model of Blau and Duncan (1967). We try to answer the research question; How does social capital contribute to the transfer of status from father to son in The Netherlands? To answer this research question, we use the Dutch Social Networks Survey. The most important result, based on a labor force sample of 471 respondents aged between 18 and 65, was that prestige as social capital is inherited and has a significant effect on one's status. However, when including social capital in the status attainment model, education is the most important predictor of one's status. Furthermore, the higher the status of the person who helps the ego to get a job, the higher the status of the attained job. Contradictory to the theory, we found no evidence of tie strength in the status attainment process.
Development of an Automatic People-Counting and Environment Monitoring System Based on Wireless Sensor Network in Real Time; To realize in Korea Mountains

In this paper, we describe an automatic people-counting and environment monitoring system based on a wireless sensor network at a mountain area. Several people-counting systems and monitoring systems have been proposed separately. However, these systems are not suitable to a place such as the mountain area because of a few problems. In this paper, we develop a system which can count the number of visiting people and sense environment information to protect an ecosystem of the mountain area. For people-counting in the mountain area, our system uses two photo-beam sensors, a big rechargeable power and a solar power. Our people-counting method is automatically to count the number of incoming and outgoing people at a special point in real time. Moreover, the environment sensors measure environment information at the mountain area, and constitute the wireless sensor network with photo-beam sensors. To establish this system in Korea Mountains, we enforced tests on the wireless communications range and the reliability of people-counting. By the testing results, we found that the developed system is suitable within 200 meters for effective wireless communications in Korea Mountains. When the width of a path up a mountain is within 1.5 m, the reliability of people-counting in our system is over 90%.
