Augmenting Domain-Specific Thesauri with Knowledge from Wikipedia

propose a new method for extending a domain-specific thesaurus with valuable information from Wikipedia. The main obstacle is to disambiguate thesaurus concepts to c orrect Wikipedia articles. Given the concept name, we firs t identify candidate mappings by analyzing article titles, the ir redirects and disambiguation pages. Then, for each candidate, we compute a link-based similarity score to all mappin gs of context terms related to this concept. The article with the highest score is then used to augment the thesaurus concept. It i s the source for the extended gloss, explaining the concept's me aning, synonymous expressions that can be used as addition al non- descriptors in the thesaurus, translations of the c oncept into other languages, and new domain-relevant concepts.
Market Design and the Evolution of the Combinatorial Clock Auction

The Combinatorial Clock Auction (CCA) is an important recent innovation in auction design which has been adopted for many spectrum auctions worldwide. Since its inception, the CCA has been in almost continual evolution. We begin by reviewing some important changes which have already occurred. Despite these enhancements, we observe that the performance of the CCA is still limited by weak activity rules, suboptimal price feedback, and a missing-bid problem. We then describe further evolutionary changes, including new activity rules, new approaches to pricing, and an integration of non-mutually-exclusive bids, which will help to address these issues.
Wi-trust: Improving Wi-Fi hotspots trustworthiness with computational trust management

In its list of top ten smartphone risks, the European Union Agency for Network and Information Security ranks Network Spoofing Attacks as number 6. In this paper, we present how we have validated different computational trust management techniques by means of implemented prototypes in real devices to mitigate malicious legacy Wi-Fi hotspots including spoofing attacks. Then we explain how some of these techniques could be more easily deployed on a large scale thanks to simply using the available extensions of Hotspot 2.0, which could potentially lead to a new standard to improve Wi-Fi networks trustworthiness.
Survey on Digital Watermarking on Medical Images

The rapid growth in information and communication technologies has advances the medical data management systems immensely. In this regard, many different techniques and also the advanced equipment like Magnetic Resonance Imaging (MRI) Scanner, Computer Tomography (CT) scanner, Positron Emission of Tomography (PET), mammography, ultrasound, radiography etc. are used. Nowadays there is a rise of various diseases, for which several diagnoses are insufficient; therefore to achieve a correct diagnostic, there is need to exchange the data over Internet, but the main problem is while exchanging the data over Internet, we need to maintain their authenticity, integrity and confidentiality. Therefore, we need a system for effective storage, transmission, controlled manipulation and access of medical data keeping its authenticity, integrity and confidentiality. In this article, we discuss various water marking techniques used for effective storage, transmission, controlled manipulation and access of medical data keeping its authenticity, integrity and confidentiality.
Ant Colony Optimization based Delay and Energy Conscious Routing Protocol for Mobile Adhoc Networks

Optimizing routing in mobile adhoc networks is a challenging task. Since mobile adhoc networks are highly dynamic topology natured, several routing protocols face the challenge of delay and energy conscious routing. This paper proposes a novel delay and energy conscious routing approach based on ant colony optimization. Based on the estimated delay and residual energy of the nearby nodes, “Delay and Energy Conscious Routing Protocol” (DECRP) finds the efficient node and sends the data packets through that node. Simulation results proved that DECRP reduces delay and energy consumption and increases packet delivery ratio than that of the “Adhoc On Demand Distance Vector” (AODV) protocol.
A Task-Level Biomechanical Framework for Motion Analysis and Control Synthesis

The behavioral richness exhibited in natural humanmotion results from the complex interplay of biomechanical and neurological factors. The biomechanical factors involve the kinematics and dynamics of the musculoskeletal system while the neurological factors involve the sensorimotor integration performed by the central nervous system (CNS). An adequate understanding of these factors is a prerequisite to understanding the overall effect on human motion as well as providing a means for synthesizing human motion. The fields of neuroscience, biomechanics, robotics, and computer graphics provide motivation, as well as tools, for understanding human motion. In neuroscience, fundamental scientific understanding drives the motivation to understand human motion, whereas, in biomechanics, clinical applications often form the driving motivation. These clinical applications involve the use of movement analysis and simulation tools to help direct patient rehabilitation as well as predict the effects of surgery on movement. In addition to the clinical desire to analyze movement there has been an emerging desire in recent years to synthetically generate human-like motion in both simulated and physical settings. In computer graphics this desire is directed toward autonomously generating realistic motion for virtual actors. The intent is to direct these virtual actors using high-level goal directed commands for which low-level motion control is automatically generated. Motivated by similar desires, the robotics community seeks a high-level control framework for robotic systems. With the recent advent of complex humanoid robots this challenge has grownmore demanding. Consistent with their anthropomorphic design, humanoid robots are intended to operate in a human-like manner within man-made environments and to promote interaction with their biological counterparts. To achieve this, common control strategies have involved generating joint space trajectories or learning specific motions, but these approaches require extensive motion planning computations and do not generalize well to related tasks.
Information Technology and Firm Boundaries: Evidence from Panel Data

Previous literature has suggested that information technology (IT) can affect firm boundaries by changing the costs of coordinating economic activity within and between firms (internal and external coordination). This paper examines the empirical relationship between IT and firm structure and evaluates whether this structure is consistent with prior arguments about IT and coordination. We formulate an empirical model to relate the use of information technology capital to vertical integration and diversification. This model is tested using an 8-year panel data set of information technology capital stock, firm structure, and relevant control variables for 549 large firms. Overall, increased use of IT is found to be associated with substantial decreases in vertical integration and weak increases in diversification. In addition, firms that are less vertically integrated and more diversified have a higher demand for IT capital. While we cannot rule out all alternative explanations for these results, they are consistent with previous theoretical arguments that both internal and external coordination costs are reduced by IT.
A novel protein modification pathway related to the ubiquitin system

Ubiquitin conjugation is known to target protein substrates primarily to degradation by the proteasome or via the endocytic route. Here we describe a novel protein modification pathway in yeast which mediates the conjugation of RUB1, a ubiquitin‐like protein displaying 53% amino acid identity to ubiquitin. We show that RUB1 conjugation requires at least three proteins in vivo. ULA1 and UBA3 are related to the N‐ and C‐terminal domains of the E1 ubiquitin‐activating enzyme, respectively, and together fulfil E1‐like functions for RUB1 activation. RUB1 conjugation also requires UBC12, a protein related to E2 ubiquitin‐conjugating enzymes, which functions analogously to E2 enzymes in RUB1–protein conjugate formation. Conjugation of RUB1 is not essential for normal cell growth and appears to be selective for a small set of substrates. Remarkably, CDC53/cullin, a common subunit of the multifunctional SCF ubiquitin ligase, was found to be a major substrate for RUB1 conjugation. This suggests that the RUB1 conjugation pathway is functionally affiliated to the ubiquitin–proteasome system and may play a regulatory role.
Urinary Biomarkers of Polycyclic Aromatic Hydrocarbons Are Associated with Cardiometabolic Health Risk

Background Polycyclic aromatic hydrocarbons (PAH) are both man-made and naturally occurring environmental pollutants that may be related to cardiometabolic health risk. Objective To determine whether PAH is associated with obesity in the adult population and to examine whether urinary concentrations of PAH metabolites are associated with differences in how obesity relates to 3 or more risk factors for the metabolic syndrome (3RFMetS), type 2 diabetes (T2D), hypertension, and dyslipidemia. Methods A total of 4765 adult participants from the 2001–2008 National Health and Nutrition Examination Survey were examined. The association between 8 urinary hydroxylated PAH metabolites, obesity, and health were examined using weighted logistic regressions adjusting for age, sex, ethnicity, PIR, smoking status, and urinary creatinine. Results There was a positive dose-dependent association between obesity and 2-phenanthrene quintiles (P trend <0.0001). Contrarily, higher quintiles of 1-naphthalene were associated with lower risk of obesity (P trend = 0.0004). For a given BMI, those in the highest quintile of 2-naphthalene, 2-fluorene, 3-fluorene and 2-phenanthrene had a 66–80% greater likelihood of 3RFMetS (P≤0.05) compared to low levels. Higher quintiles of 1-naphthalene, 2-naphthalene, 2-phenanthrene and 1-pyrene were associated with a 78–124% greater likelihood of T2D (P≤0.05) compared to low levels while high 1-naphthalene, 2-naphthalene, 2-fluorene, 3-fluorene and 2-phenanthrene were associated with a 38–68% greater likelihood of dyslipidemia (P≤0.05) compared to lower levels. Finally, 2-naphthalene and 2-phenanthrene were positively associated with hypertension (P trend = 0.008 and P trend = 0.02 respectively). Conclusions PAH is related to obesity and the expression of a number of obesity-related cardiometabolic health risk factors. Future research is needed to bring to light the mechanistic pathways related to these findings.
An agent-based framework for dynamic multi-period continuous double auctions in B2B exchanges

Business-to-business (B2B) exchanges provide opportunities for companies to streamline their supply chains in dynamic business situations, but also create new management challenges. Managers are faced with more buying and selling decisions, more available information, and even new problems such as speculation. Due to these new challenges, trading support systems will play an important role in helping companies achieve maximum profits in B2B exchanges. This paper presents an agent-based framework focusing on two core functionalities of such systems, bidding and speculating, in the context of Continuous Double Auction (CDA). The CDA is a market institution where a group of buyers and a group of sellers simultaneously and asynchronously announce bids and offers. [1, 2, 3, 5] and [6] have designed different CDA bidding agents such as Zero-Intelligence(ZI) traders, Zero-Intelligence Plus(ZIP) traders and GD traders. All of these models assume constant supply and demand. We extend these works to more dynamic and realistic B2B exchange situations where both demand and supply change from period to period. Specifically, we focus on designing algorithms that enable agents to make speculation decisions, since the action of speculation, motivated by changing demand and supply, is one fundamental aspect of exchanges in general, and is the main way to hedge against costly shortages in B2B exchanges.
X-ray Emission from Nearby M-dwarfs : the Supersaturation Phenomenon

A rotation rate and X-ray luminosity analysis is presented for rapidly rotating single and binary M-dwarf systems. X-ray luminosities for the majority of both single & binary M-dwarf systems with periods below ≃ 5−6 days (equatorial velocities, Veq∼>6 km s) are consistent with the current rotation-activity paradigm, and appear to saturate at about 10 of the stellar bolometric luminosity. The single M-dwarf data show tentative evidence for the super-saturation phenomenon observed in some ultra-fast rotating (∼>100 km s ) G & K-dwarfs in the IC 2391, IC 2602 and Alpha Persei clusters. The IC 2391 M star VXR60b is the least X-ray active and most rapidly rotating of the short period (Prot∼<2 days) stars considered herein, with a period of 0.212 days and an X-ray activity level about 1.5 sigma below the mean X-ray emission level for most of the single M-dwarf sample. For this star, and possibly one other, we cautiously believe that we have identified the first evidence of super-saturation in M-dwarfs. If we are wrong, we demonstrate that only M-dwarfs rotating close to their break up velocities are likely to exhibit the super-saturation effect at X-ray wavelengths. The M-dwarf X-ray data also show that there is no evidence for any difference in the X-ray behaviour between the single and binary systems, because for the single stars, the mean log Lx/Lbol = −3.21 ± 0.04 (0.2∼<Prot∼<10.1 days), whereas for the binary stars, the mean log Lx/Lbol = −3.19± 0.10 (0.8∼<Prot∼<10.4 days). Furthermore, we show that extremely X-ray active M-dwarfs exhibit a blue excess of about 0.1 magnitudes in U−B compared to less active field M-dwarfs. Such an excess level is comparable to that observed for extremely chromospherically active M-dwarfs. Moreover, as is the case for M-dwarf Ca II H & K activity levels, there is an exclusion zone of X-ray activity between the extremely active M-dwarfs and the less active ones.
Combinatorial bases for covariant representations of the Lie superalgebra gl(m|n)

Covariant tensor representations of gl(m|n) occur as irreducible components of tensor powers of the natural (m+n)-dimensional representation. We construct a basis of each covariant representation and give explicit formulas for the action of the generators of gl(m|n) in this basis. The basis has the property that the natural Lie subalgebras gl(m) and gl(n) act by the classical Gelfand-Tsetlin formulas. The main role in the construction is played by the fact that the subspace of gl(m)-highest vectors in any finite-dimensional irreducible representation of gl(m|n) carries a structure of an irreducible module over the Yangian Y(gl(n)). One consequence is a new proof of the character formula for the covariant representations first found by Berele and Regev and by Sergeev.
Hyperideal polyhedra in hyperbolic 3-space

A hyperideal polyhedron is a non-compact polyhedron in the hyperbolic 3-space 3 which, in the projective model for 3 ⊂ 3 , is just the intersection of 3 with a projective polyhedron whose vertices are all outside 3 and whose edges all meet 3 . We classify hyperideal polyhedra, up to isometries of 3 , in terms of their combinatorial type and of their dihedral angles. R´´ (Polyedres hyperideaux de l'espace hyperbolique de dimension 3) Un polyedre hyperideal est un polyedre non-compact de l'espace hyperbolique 3 de dimension 3 qui, dans le modele projectif pour 3 ⊂ 3 , est simplement l'intersection de 3 avec un polyedre projectif dont les sommets sont tous en dehors de 3 et dont toutes les aretes rencontrent 3 . Nous classifions ces polyedres hyperideaux, ` som´ de 3 pres, en fonction de leur type combinatoire et de leurs angles diedraux.
The Future is Convex

We present analytical approximation formulae for the price of interest rate futures contracts derived from the yield curve dynamics prescribed by a Libor market model allowing for an implied volatility skew generated by displaced diffusion equations. The derivation of the formulae by the aid of It ˆ o-Taylor expansions and heuristic truncations and transformations is shown, and the results are tested against numerical calculations for a variety of market parameter scenarios. The new futures convexity formulae are found to be highly accurate for all relevant market conditions, and can thus be used as part of yield curve stripping algorithms.
Overexpression of Tau Protein Inhibits Kinesin-dependent Trafficking of Vesicles, Mitochondria, and Endoplasmic Reticulum: Implications for Alzheimer's Disease

The neuronal microtubule-associated protein tau plays an important role in establishing cell polarity by stabilizing axonal microtubules that serve as tracks for motor-protein–driven transport processes. To investigate the role of tau in intracellular transport, we studied the effects of tau expression in stably transfected CHO cells and differentiated neuroblastoma N2a cells. Tau causes a change in cell shape, retards cell growth, and dramatically alters the distribution of various organelles, known to be transported via microtubule-dependent motor proteins. Mitochondria fail to be transported to peripheral cell compartments and cluster in the vicinity of the microtubule-organizing center. The endoplasmic reticulum becomes less dense and no longer extends to the cell periphery. In differentiated N2a cells, the overexpression of tau leads to the disappearance of mitochondria from the neurites. These effects are caused by tau's binding to microtubules and slowing down intracellular transport by preferential impairment of plus-end–directed transport mediated by kinesin-like motor proteins. Since in Alzheimer's disease tau protein is elevated and mislocalized, these observations point to a possible cause for the gradual degeneration of neurons.
A Ca2+/Calmodulin-Dependent Protein Kinase ModulatesDrosophila Photoreceptor K+ Currents: A Role in Shaping the Photoreceptor Potential

Light activation of Drosophila photoreceptors leads to the generation of a depolarizing receptor potential via opening of transient receptor potential and transient receptor potential-like cationic channels. Counteracting the light-activated depolarizing current are two voltage-gated K+ conductances, IA andIK, that are expressed in these sensory neurons. Here we show that Drosophilaphotoreceptors IA andIK are regulated by calcium–calmodulin (Ca2+/calmodulin) via a Ca2+/calmodulin-dependent protein kinase (CaM kinase), with IK being far more sensitive than IA. Inhibition of Ca2+/calmodulin by N-(6 aminohexyl)-5-chloro-1-naphthalenesulfonamide or trifluoperazine markedly reduced the K+ current amplitudes. Likewise, inhibition of CaM kinases by KN-93 potently depressedIK and accelerated its C-type inactivation kinetics. The effect of KN-93 was specific because its structurally related but functionally inactive analog KN-92 was totally ineffective. In Drosophila photoreceptor mutantShKS133 , which allows isolation ofIK, we demonstrate by current-clamp recording that inhibition of IK by quinidine or tetraethylammonium increased the amplitude of the photoreceptor potential, depressed light adaptation, and slowed down the termination of the light response. Similar results were obtained when CaM kinases were blocked by KN-93. These findings place photoreceptor K+ channels as an additional target for Ca2+/calmodulin and suggest thatIK is well suited to act in concert with other components of the signaling machinery to sharpen light response termination and fine tune photoreceptor sensitivity during light adaptation.
A “Retained Image Appearance” Metric For Full Tonal Scale, Colorimetric Evaluation Of Photographic Image Stability

This paper describes a computational model based on CIELAB colorimetry and full tonal scale evaluation to define objective boundary conditions for “Retained Image Appearance” in a photograph where 100% retention equates to no visual change and 0% retention means total functional loss of image information content. The “Retained Image Appearance” model, I*, examines the color information (hue and chroma) and the black-and-white spatial information (lightness and contrast) in order to characterize the complete life cycle of a photograph as it ages with respect to color, contrast, and lightness. The I* model can also be used to compare tone reproduction accuracy between different renditions of a photographic image and may therefore have applicability in initial print or proof print quality studies as well.
Zinc Supplementation against Eimeria acervulina-Induced Oxidative Damage in Broiler Chickens

This study was undertaken to determine the dietary supplements of Zn containing diet on the antioxidant status in chickens experimentally infected with Eimeria acervulina. The antioxidant status was monitored via determination of MDA concentrations and erythrocyte SOD and CAT activities, as well as vitamin E, vitamin C, Cu, and Zn in liver, muscle, and serum. The results showed increased MDA (P < .05), CAT (P < .001), and decreased SOD (P < .001) in the infected birds. Significant changes in Cu and Zn concentrations and dramatically reduction of vitamin C and E concentrations in the infected chickens were found. The observed deviations in the studied enzymes and nonenzymatic parameters evidence the occurrence of oxidative stress following the infection and impaired antioxidant status of chickens, infected with Eimeria acervulina. Our results proved the ameliorating role of CuZn(OH)3Cl (0.170 g per kg food) against Eimeria acervulina-induced oxidative damage in infected chickens.
Real-Time Proof of Violation for Cloud Storage

In this paper we define and explore proof of violation (POV) for cloud storage systems. A POV scheme enables a user or a service provider to produce a precise proof of either the occurrence of the violation of properties or the innocence of the service provider. POV schemes are solutions for obtaining mutual nonrepudiation between users and the service provider in the cloud. Existing solutions for obtaining mutual nonrepudiation only support epoch-based POV. The drawback of an epoch-based POV scheme is that violation of properties can only be detected at the end of an epoch. We propose a real-time POV scheme in which the auditing can be performed at the time of each file operation. To the best of our knowledge, it is the first scheme that can perform real-time POV for cloud storage. In addition, each client device only needs to store a partial hash tree of files in an account. Experimental results are presented that demonstrate the feasibility of the proposed scheme. Service providers of cloud storage can use the proposed scheme to provide a mutual nonrepudiation guarantee in their service-level agreements.
