Comparative Transcriptional Profiling of Primed and Non-primed Rice Seedlings under Submergence Stress

Submergence stress is a limiting factor for direct-seeded rice systems in rainfed lowlands and flood-prone areas of South and Southeast Asia. The present study demonstrated that submergence stress severely hampered the germination and seedling growth of rice, however, seed priming alleviated the detrimental effects of submergence stress. To elucidate the molecular basis of seed priming-induced submergence tolerance, transcriptome analyses were performed using 4-day-old primed (selenium-Se and salicylic acid-SA priming) and non-primed rice seedlings under submergence stress. Genomewide transcriptomic profiling identified 2371 and 2405 transcripts with Se- and SA-priming, respectively, that were differentially expressed in rice compared with non-priming treatment under submergence. Pathway and gene ontology term enrichment analyses revealed that genes involved in regulation of secondary metabolism, development, cell, transport, protein, and metal handling were over-represented after Se- or SA-priming. These coordinated factors might have enhanced the submergence tolerance and maintained the better germination and vigorous seedling growth of primed rice seedlings. It was also found that many genes involved in cellular and metabolic processes such as carbohydrate metabolism, cellular, and metabolic biosynthesis, nitrogen compound metabolic process, transcription, and response to oxidative stress were induced and overlapped in seed priming treatments, a finding which reveals the common mechanism of seed priming-induced submergence tolerance. Taken together, these results may provide new avenues for understanding and advancing priming-induced responses to submergence tolerance in crop plants.
Understanding Search Behavior of Low-Literacy & Low English Comprehension Users

This paper presents a user study based log analysis of the search behavior of low-literacy users in the developing world. It is first step towards Web search personalization for such users, which has been hindered by a paucity of appropriate data for inducing effective user models that target the real problems in information access for low literacy user population. We demonstrate the variations in the behavior of such users with the ‘typical’ user population by comparing the user actions during an Information Seeking session. The users deviated from the ‘ideal’ search behavior during the course of the information-seeking session with inefficient use of querying and subsequent navigation of the search results. We present an analysis that offers intuitions for more efficient information seeking practices for such users.
Hydropower production schedule optimization using genetic algorithms

In our modern society optimizing water usage is a topic of upmost importance because of the multiple benefits it provides. The two most important ones are: drinking water and energy. Cascaded dams have been constructed all over the world to provide the surrounding area with a steady supply of both. The cascaded dams are controlled via a SCADA (Supervisory Control and Data Acquisition) system. Genetic algorithms can be used to schedule the functioning of each hydro turbine in each power plant, after the final iteration we would have a solution that shows the optimal way to use the water. This can then be applied on the SCADA system and it would insure not just that the required grid energy was generated but also that the water levels in each dam are as close to the normal retention level as possible.
The Triple-Ring Nebula Around SN 1987A: Fingerprint of a Binary Merger

Supernova 1987A, the first naked-eye supernova observed since Kepler's supernova in 1604, defies a number of theoretical expectations. Its anomalies have long been attributed to a merger between two massive stars that occurred some 20,000 years before the explosion, but so far there has been no conclusive proof that this merger took place. Here, we present three-dimensional hydrodynamical simulations of the mass ejection associated with such a merger and the subsequent evolution of the ejecta, and we show that this accurately reproduces the properties of the triple-ring nebula surrounding the supernova.
The education of Europe : apprehending EU educational policies

This chapter analyses educational policies in the European Union. Because the Unionization process is taking place on so many different levels – ranging from the local to the national, and the national to the global (and vice-versa) – it is possible to undertake this project with reference to any number of dimensions. This task is also complicated by the interconnected processes of Europeanization and globalization, as well as the temptation to oppose nation-states to the European Union, “localism” with “cosmopolitanism”, etc. (Bauman, 2001; Breckenridge et al., 2002). The layer which we have chosen intends to build the European Union as the main explanatory level of analysis. In fact, it is necessary to determine the nature of this unprecedented political entity, in order to apprehend its influence in the formulation of educational policies. Adopting this perspective, we hope to displace and replace ourselves in the European political debate, opening the possibility for new questions and understandings.
Asian Competitive Devaluations

In this paper we examine three issues. The first is the path of China's nominal and real exchange rates since 1990. As it turns out, this is more complicated than is commonly assumed, with basic results exhibiting sensitivity to the exchange rate measure used. We conclude that while China did experience a large nominal depreciation, its much higher relative inflation eroded this devaluation, and in real terms the reminbi has actually appreciated during the 1990s. The Chinese devaluation was at best a contributing factor to the Asian financial crises, not their primary cause.
Distributed Computation of the Cech Complex and Applications in Wireless Networks

In this paper, we introduce a distributed algorithm to compute th\v{e} Cech complex. This algorithm is aimed at solving coverage problems in self organized wireless networks. Two applications based on the distributed computation of th\v{e} Cech complex are proposed. The first application detects coverage holes while the later one optimizes coverage of wireless networks.
Insulin Granule Recruitment and Exocytosis Is Dependent on p110γ in Insulinoma and Human β-Cells

OBJECTIVE Phosphatidylinositol 3-OH kinase (PI3K) has a long-recognized role in β-cell mass regulation and gene transcription and is implicated in the modulation of insulin secretion. The role of nontyrosine kinase receptor–activated PI3K isoforms is largely unexplored. We therefore investigated the role of the G-protein–coupled PI3Kγ and its catalytic subunit p110γ in the regulation of insulin granule recruitment and exocytosis. RESEARCH DESIGN AND METHODS The expression of p110γ was knocked down by small-interfering RNA, and p110γ activity was selectively inhibited with AS605240 (40 nmol/l). Exocytosis and granule recruitment was monitored by islet perifusion, whole-cell capacitance, total internal reflection fluorescence microscopy, and electron microscopy in INS-1 and human β-cells. Cortical F-actin was examined in INS-1 cells and human islets and in mouse β-cells lacking the phosphatase and tensin homolog (PTEN). RESULTS Knockdown or inhibition of p110γ markedly blunted depolarization-induced insulin secretion and exocytosis and ablated the exocytotic response to direct Ca2+ infusion. This resulted from reduced granule localization to the plasma membrane and was associated with increased cortical F-actin. Inhibition of p110γ had no effect on F-actin in β-cells lacking PTEN. Finally, the effect of p110γ inhibition on granule localization and exocytosis could be rapidly reversed by agents that promote actin depolymerization. CONCLUSIONS The G-protein–coupled PI3Kγ is an important determinant of secretory granule trafficking to the plasma membrane, at least in part through the negative regulation of cortical F-actin. Thus, p110γ activity plays an important role in maintaining a membrane-docked, readily releasable pool of secretory granules in insulinoma and human β-cells.
On the Reuse of SOA Components on Business Process Analysis Stages

In 2005 four German universities created a research program to improve and standardize its administration processes. Therefore, reams of processes have been analyzed and core functions identified. Automatable core functions have been afterwards implemented as webservices using the Service-oriented architecture (SOA) paradigm. For reasons of reuse these web-services have been documented using a service catalogue. However, a real advantage of SOA does not evolve until complex business services become configurable on business level. Thereby, the problem arises to make the meaning of the services understandable to non-IT employees, like business analysts. In this paper, we introduce a framework for building up a service catalogue addressing business analysts instead of IT engineers. Therefore, we discuss the composition of webservices to more complex business components. These components are described on an ITlevel addressing the catalogue manager, but contain also non-formal information for business analysts. Thus, the redesign of the universities processes can be supported now, using web-services encapsulated by business components. Our findings can help to increase the usage and acceptance of web-services on a business process level.
Pulmonary vein ablation for idiopathic atrial fibrillation: six month outcome of first procedure in 100 consecutive patients

Objectives: To report six month outcome in patients undergoing their first pulmonary vein ablation procedure for idiopathic atrial fibrillation (AF) at a “non-pioneering” hospital. Design: Prospective observational study. Setting: Specialist electrophysiology unit at a university hospital. Patients: The first 100 consecutive patients undergoing their first pulmonary vein catheter ablation procedure for highly symptomatic, drug resistant AF in the period 1999–2002. Main outcome measures: Incidence of symptomatic or asymptomatic, Holter documented AF six months after ablation. Results: Mean patient age was 52 years (range 23–73 years), mean length of AF history 53 months (range 6–180 months), mean number of antiarrhythmic drug failures was 3 (range 1–5), and 81 were men. At the time of the ablation procedure, 64 had progressed to persistent AF and 23 had increased transverse left atrial diameter. The number of pulmonary veins ablated in each patient was one in 11, two in 45, three in 36, and four in 8. Six months after ablation, 55 patients were consistently in sinus rhythm, asymptomatic, and without any Holter evidence of AF. The chance of being in sinus rhythm was 73% (29 of 64) in those with paroxysmal as compared with only 45% (26 of 36) in those with persistent AF at the time of ablation (p = 0.01). Outcome was not influenced by patient age, length of AF history, or duration of persistent AF before ablation or to left atrial dimension. Follow up was complete and no patient has died or experienced a stroke during or after ablation; nor have any developed symptoms of late pulmonary vein stenosis. However, other complications occurred during or shortly after the procedure in 12 patients, including cardiac tamponade in six. Conclusions: In selected patients with drug resistant AF, focal pulmonary vein catheter ablation offers a realistic prospect of achieving stable sinus rhythm compared with alternatives. However, it is a complex form of ablation with a significant risk of serious complications. Although a new milestone in arrhythmia management, the optimum ablation technique is still evolving and any impact on the natural history of AF remains to be determined.
Suffix-centered allomorphy in Korean

Kim, Gyung-Ran. 2006. Suffix-centered allomorphy in Korean. Studies in Phonetics, Phonology and Morphology. 12.2. 265-281. This paper is to show that problems related with suffix allomorph selection cannot be solved at one swoop and to suggest that the job be divided between morphology and phonology in sequential steps. Drawing on the fact that neither rule-based analyses positing suffix-initial // for alternating suffixes in the underlying representation nor OTbased ones positing both allomorphs in the input in adherence to Richness of the Base cannot describe suffix allomorph selection adequately, the study allows only one morph in the input. The inconsistent behavior of /l/-final stems in taking Cand V-initial suffixes and the existence of non-alternating suffixes composed of similar segments lead to the argument that allomorph selection is suffix-centered, not stem-centered. It is proposed that each allomorph of alternating suffixes is subcategorized with respect to the features of its preceding stem-final segment. Particularly, the revival of the [vocalic] feature is instrumental to the explanation of the inconsistent behavior of the stem-final /l/, which forms a natural class of [+vocalic] with vowels and liquid /l/ and forms another one of [+consonantal] with all consonants.

CAX‐ing a wide net: Cation/H+ transporters in metal remediation and abiotic stress signalling

Abstract Cation/proton exchangers (CAXs) are a class of secondary energised ion transporter that are being implicated in an increasing range of cellular and physiological functions. CAXs are primarily Ca2+ efflux transporters that mediate the sequestration of Ca2+ from the cytosol, usually into the vacuole. Some CAX isoforms have broad substrate specificity, providing the ability to transport trace metal ions such as Mn2+ and Cd2+, as well as Ca2+. In recent years, genomic analyses have begun to uncover the expansion of CAXs within the green lineage and their presence within non‐plant species. Although there appears to be significant conservation in tertiary structure of CAX proteins, there is diversity in function of CAXs between species and individual isoforms. For example, in halophytic plants, CAXs have been recruited to play a role in salt tolerance, while in metal hyperaccumulator plants CAXs are implicated in cadmium transport and tolerance. CAX proteins are involved in various abiotic stress response pathways, in some cases as a modulator of cytosolic Ca2+ signalling, but in some situations there is evidence of CAXs acting as a pH regulator. The metal transport and abiotic stress tolerance functions of CAXs make them attractive targets for biotechnology, whether to provide mineral nutrient biofortification or toxic metal bioremediation. The study of non‐plant CAXs may also provide insight into both conserved and novel transport mechanisms and functions.
Additive noise compensation in the i-vector space for speaker recognition

State-of-the-art speaker recognition systems performance degrades considerably in noisy environments even though they achieve very good results in clean conditions. In order to deal with this strong limitation, we aim in this work to remove the noisy part of an i-vector directly in the i-vector space. Our approach offers the advantage to operate only at the i-vector extraction level, letting the other steps of the system unchanged. A maximum a posteriori (MAP) procedure is applied in order to obtain clean version of the noisy i-vectors taking advantage of prior knowledge about clean i-vectors distribution. To perform this MAP estimation, Gaussian assumptions over clean and noise i-vectors distributions are made. Operating on NIST 2008 data, we show a relative improvement up to 60% compared with baseline system. Our approach also outperforms the “multi-style” backend training technique. The efficiency of the proposed method is obtained at the price of relative high computational cost. We present at the end some ideas to improve this aspect.
Prominin 1/CD133 Endothelium Sustains Growth of Proneural Glioma

In glioblastoma high expression of the CD133 gene, also called Prominin1, is associated with poor prognosis. The PDGF-driven proneural group represents a subset of glioblastoma in which CD133 is not overexpressed. Interestingly, this particular subset shows a relatively good prognosis. As with many other tumors, gliobastoma is believed to arise and be maintained by a restricted population of stem-like cancer cells that express the CD133 transmembrane protein. The significance of CD133+ cells for gliomagenesis is controversial because of conflicting supporting evidence. Contributing to this inconsistency is the fact that the isolation of CD133+ cells has largely relied on the use of antibodies against ill-defined glycosylated epitopes of CD133. To overcome this problem, we used a knock-in lacZ reporter mouse, Prom1lacZ/+, to track Prom1+ cells in the brain. We found that Prom1 (prominin1, murine CD133 homologue) is expressed by cells that express markers characteristic of the neuronal, glial or vascular lineages. In proneural tumors derived from injection of RCAS-PDGF into the brains of tv-a;Ink4a-Arf−/− Prom1lacZ/+ mice, Prom1+ cells expressed markers for astrocytes or endothelial cells. Mice co-transplanted with proneural tumor sphere cells and Prom1+ endothelium had a significantly increased tumor burden and more vascular proliferation (angiogenesis) than those co-transplanted with Prom1− endothelium. We also identified specific genes in Prom1+ endothelium that code for endothelial signaling modulators that were not overexpressed in Prom1− endothelium. These factors may support proneural tumor progression and could be potential targets for anti-angiogenic therapy.
Comparative study of design of PIDA controller for induction motor

PID controller gives satisfactory results up to second order as it is difficult to get desired response quality in third and higher order systems using analytical approach, as the number of zeros provided by PID controller is less than the order of the plant. PIDA (Proportional-Integral-Derivative-Acceleration) controllers are found to be suitable for third and higher order systems. This paper studies the design of PIDA controller using three different approaches i.e. Dorf Approach, Coefficient Diagram Method and Kitti's Method applied to speed control of 3-phase induction motor.
Sphere based topology: A novel idea for NoCs

Topology has significant effects on the most important parameters of a network such as latency and power consumption. The sphere based topology is a new structure for Network-on-Chips that forms in sphere shape. We have used a Zone-Order label based algorithm for the routing that is a general algorithm for routing requirements, and it is based on spanning tree. We have compared sphere based topology with mesh and torus those are two common topologies. Based on the results, the sphere based topology is the best of the two others in latency and power consumption comparison.
Split-node on overlapping community in dense social networks

This project is intended to put forward a new model and algorithm to deal with graph partitioning, which is an attractive part in the field of social network analysis. In the recent years, an exponent increasing number of studies have been undertaken to process social network data, partly as a result of the fact that so much social network data has become available. Another reason is that the significance has been public aware of in the sense of economic and research value. However, the results are not that perfect because the mathematical models before were simple. The real-world situation that one may belong to several groups should also be taken into consideration. In the mean time, overlapping communities will bring other problems for the graph partitioning algorithm. In this paper, we present a split-node method, a novel algorithm to detect overlapping communities in large data graphs, based on the summary of several classical graph partitioning algorithms.
Kemeruapan pulangan pasaran indeks syariah Kuala Lumpur (KLSI): analisis model GARCH

Volatility of stock returns can be defined as a dispersion of stock return mean, which is known as variance. Information and knowledge about the behaviour of stock return volatility is pertinently important to economists and financial analysts in order to solve related economic problems. Poterba and Summers(1986) relate the influence of continuous volatility in relation with changes in stock price volatility, while Bollerslev, Chou and Kroner, (1992) mentioned that there are three factors that influence the volatility behaviour which are continuous volatility, means-variance and asymmetric relationship. This research used the ARCH family model in analysing the volatility of "syariah" compliant stock return at BSKL because of its importance in analysing and predicting volatility. Empirical estimators used were syariah compliant stock prices for every counter, volume trading, Dow Jones Industrial Index, Syariah Index, Composite Index, lnterbank Interest Rate and Islamic Interbank Interest Rates. The research duration was from 2 January 1995 to 13 June 2003. The duration was then divided into two periods with the first period starting from 2 January 1995 to 29 April 1999, which was before the launch of syariah compliant stock. The second was after the launch of syariah compliant stock from 30 April 1999 to 13 June 2003.
Genetic and Biochemical Analysis of cis Regulatory Elements within the Keratinocyte Enhancer Region of the Human Papillomavirus Type 31 Upstream Regulatory Region during Different Stages of the Viral Life Cycle

ABSTRACT Using linker scanning mutational analysis, we recently identified potential cis regulatory elements contained within the 5′ upstream regulatory region (URR) domain and auxiliary enhancer (AE) region of the human papillomavirus type 31 (HPV31) URR involved in the regulation of E6/E7 promoter activity at different stages of the viral life cycle. For the present study, we extended the linker scanning mutational analysis to identify potential cis elements located in the keratinocyte enhancer (KE) region (nucleotides 7511 to 7762) of the HPV31 URR and to characterize cellular factors that bind to these elements under conditions representing different stages of the viral life cycle. The linker scanning mutational analysis identified viral cis elements located in the KE region that regulate transcription in the presence and absence of any viral gene products or viral DNA replication and determine the role of host tissue differentiation on viral transcriptional regulation. Using electrophoretic mobility shift assays, we illustrated defined reorganization in the composition of cellular transcription factors binding to the same cis regulatory elements at different stages of the HPV differentiation-dependent life cycle. Our studies provide an extensive map of functional elements in the KE region of the HPV31 URR, identify cis regulatory elements that exhibit significant transcription regulatory potential, and illustrate changes in specific protein-DNA interactions at different stages of the viral life cycle. The variable recruitment of transcription factors to the same cis element under different cellular conditions may represent a mechanism underlying the tight link between keratinocyte differentiation and E6/E7 expression.
