Privacy-Preserving Fraud Detection via Cooperative Mobile Carriers with Improved Accuracy

With the explosive growth of users in mobile carrier, telecommunication fraud causes a serious loss to both of the users and carriers. The academia has an increasing interest in the issue of detecting and recognizing fraudster, and varies strategies have been proposed to prevent the attack and fraudulent activity. However, fraudsters are always inclined to hide their identity and perform the fraudulent activity through different mobile carriers, which makes the previous methods less effective in fraud detection. In this paper, we propose a novel strategy with a high accuracy and security through the cooperation among mobile carriers. We introduce the Latent Dirichlet Allocation (LDA) model to profile users in different carriers. In order to match the fraud accounts, we propose a strategy based on Maximum Mean Discrepancy (MMD) to analyze and compare the distribution of statistical samples. Meantime, during the cooperation of carriers, there is a risk of privacy disclosure. To deal with this weakness, we also demonstrate that our method can detect the fraudulent accounts without leaking the private records and data of user accounts based on the differential privacy.
ESTIMATES OF HERITABILITY AND CORRELATION FOR MILK AND GROWTH TRAITS IN ZARAIBI GOAT

Records from the El-Serw research station belonging to Animal Production Research Institute were used to estimate the genetic parameters for the economically most important milk and growth traits in the Zaraibi goat breed. There were 99 and 110 half-sib families over the periods 1995-2003 and 1990-2003 for milk and growth traits, respectively. Milk traits were, milk yield during the first 90 days and the total yield and the length of lactation period. The weight was recorded at birth, 90, 180 and 365 days of age. Mixed model methodology based on a multi-trait animal model was used to estimate the genetic and phenotypic parameters. A repeatability model was used for milk traits. Heritability for milk yield was 0.27 (90 days) and 0.35 (total) with a genetic correlation of 0.89 between them. The lactation period had heritability 0.15 and it was naturally positively correlated with yield, especially with the total yield (0.80). Therefore a selection program on the earlier 90 days yield record would give the best annual genetic changes for milk traits. The heritability for weight traits varied between 0.12 and 0.33 with high (0.42-0.82) positive genetic correlations between them. The pre-weaning gain (from birth to 90 days) is a very useful tool for selection, as it has a satisfactory heritability (0.33), it is very highly correlated with the post-weaning gain (from weaning to 6 months) and it is available well before any selection decisions are made.
A Central and Secured Logging Data Solution for Xen Virtual Machine

Logging data is a valuable and an important information to reveal the attacker's activities and to recover broken system. Unfortunately, once the attacker successfully penetrates a protected system, he never fails to either modify the logging data, or even worse, delete them to cover his traces. To avoid such a disaster, it is best to keep logging data in another machine by forwarding them to a central logging server. However, this approach has a flaw: while transmitting on network, the data could be illegally sniffed or the traffic might be secretly redirected to a malicious machine. This paper proposes a novel method named Xenlog to secure logging data for systems run on Xen virtual machine: the solution does not use network stack to send data. Experimental and resulted tool proves that this approach is more secure than the traditional solution, while logging process is far more effective (nearly 21 times faster) and more reliable.

L’accroissement de la durée des conventions collectives de travail québécoises depuis 20 ans : nouvelle normalité, partenariat consolidé ou manifestation du pouvoir patronal ?

En quoi la duree des conventions collectives de travail est-elle liee a leur contenu ? En se basant sur le cas du secteur prive quebecois qui a vu la duree des conventions s’accroitre depuis 1994, cette recherche traite des interets patronaux et syndicaux lies a cet enjeu dans un systeme de relations industrielles decentralise. L’analyse de pres de 5 300 conventions collectives met a l’epreuve trois theses susceptibles d’expliquer cette evolution : 1) elle reflete une nouvelle normalite decoulant de la volonte des parties de disposer de periodes de stabilite plus longues pour faire face a la mondialisation ; 2) elle s’accompagne de nouveaux objets de negociation de nature partenariale negocies localement et 3) elle constitue un nouveau levier de pouvoir patronal pour faire pression sur les conditions de travail des salaries. Les resultats montrent que la convention de plus longue duree s’est largement imposee comme la nouvelle « norme », mais que le rapport de force favorable aux employeurs parait expliquer le caractere defavorable pour les travailleurs et les syndicats des conventions les plus longues.
Investigation of the photoelectrochemical effect in optoelectrodes and potential uses for implantable electrode characterization*

The combination of optical stimulation and electrical recording is commonly employed in neuroscience research. Researchers using optogenetics are familiar with the photo-induced “artifacts” that arise from illumination of an electrode array. We sought to characterize this photoelectrochemical (PEC) effect to understand the underlying mechanism seen on NeuroNexus optoelectrodes. In doing so, we discovered that the phenomenon is inversely proportional to electrode site area in the same manner as electrical impedance measurements. We have applied the PEC effect as a method of electrode evaluation and show that a PEC measurement system can be both faster and more effective than impedance at sensing defects in high-throughput biomedical device testing.
Effectiveness of laser-assisted irrigation and passive ultrasonic irrigation techniques on smear layer removal in middle and apical thirds.

The purpose of this study was to investigate the evaluation of laser-assisted irrigation (LAI) on the removal of the smear layer as compared to passive ultrasonic irrigation (PUI). Forty-eight single-rooted, upper-central incisor teeth were selected and prepared with ProTaper rotary instruments up to size #40 (F4) at the working lengths. Specimens were divided into four groups, as follows: (a) PUI with 5 mL of 2.5% NaOCl for 60 s; (b) PUI with 2.5 mL of 17% EDTA and 2.5 mL of 2.5% NaOCl each for 30 s; (c) LAI with 5 mL of 2.5% NaOCl for 60 s; and (d) LAI with 2.5 mL of 17% EDTA and 2.5 mL of 2.5% NaOCl each for 30 s. In the PUI groups, the ultrasonically activated file was inserted 1 mm short of the working length, but in the LAI groups, the fiber tip was applied into the pulp chamber. LAI in the pulp chamber with the combination of 17% EDTA and 2.5% NaOCl removed more of the smear layer than the other groups (p < 0.018). LAI in the pulp chamber with the combination of 2.5% NaOCl and 17% EDTA better removed the smear layer than LAI applied similarly but without EDTA or PUI with the same NaOCl and EDTA combinations using an ultrasonically activated file inserted 1 mm short of the working length.
Translation of gag, pro, and pol gene products of human T-cell leukemia virus type 2

Sequence analysis of human T-cell leukemia proviral DNA revealed three open reading frames arranged at a -1 position relative to one another. On the basis of homology to other retroviruses, these open reading frames were assigned to the gag, pro, and pol genes. To characterize the primary protein products of these genes and their modes of synthesis, a DNA clone of human T-cell leukemia virus type 2 was transcribed and translated in vitro. Analysis of the viral proteins revealed three polyproteins with molecular masses of 58, 75, and 112 kilodaltons at relative frequencies of 100:13:0.9, respectively. These proteins were mapped on the viral genome by both internal deletions and 3'-end truncations at gag, pro, and pol, respectively. The results indicate that translation of the pol gene requires two independent frameshift events, and the readthrough frequencies at the two frameshift sites appeared to be similar.
Absorption of Intratympanic Topical Antibiotics

For decades, oto logists, physiologists, and anatomists have studied the mechanism of systemic and ototopical drug uptake by the inner ear. During that time , otologists have searc hed for a safe and effective topical medication to treat otitis externa, otit is med ia, and other otomasto id infections inpatients with and witho ut tympanic membrane perforations. Topicalciprofloxacin has become a widely used medication for treating otitis media in patients with a perforated tympanic memb rane . Its popularity can be attr ibuted to its potency, broad spectrum of coverage, and safety. To the best of our knowledge, intratympanic ciprofloxacin has never been implicated as a cause of ototoxicity. Still , some quest ions rema in about its absorption. Specifically:
Communication and computation tradeoffs for a network of intelligent sensors

A linear network of intelligent sensors is examined. The objective is to solve a computational problem in a minimal amount of time. The sensors in the networks can be equipped either with front-end processors for communication off-loading or without front-end processors. The cases of equal division of processing load and optimal division of processing load are discussed for both the network with front-end processors and the network without front-end processors. An example of the inclusion of the solution time, the time taken for sensors to report the solution back to originator, is also presented. <<ETX>>
HIERARCHICAL REASONING IN TIME AND SPACE

The study of spatial relationships has been one of the most active areas in GIS research over the past twenty years. Many formal models have been proposed for the definition of topological or cardinal relationships. However, these approaches often consider space as a static continuum which does not integrate the temporal dimension. Recent progress in spatio-temporal GIS research attempts to extend the representation of spatial relationships to the integration of the life and motion of spatial entities or in other words, the study of the evolution of spatial entities. However, these models generally consider the evolution of spatial entities, that is, entities constrained by a filiation tree. This paper proposes an alternative view of relationships in space and time, that is, we consider independent entities in space and time. The temporal and spatial dimensions are modelled using a hierarchical approach that allows the description of relationships at different levels of abstraction. We show that hierarchical reasoning in time and space supports the identification of modular relationships, generally not identified in existing temporal GIS models, and suggest that their use has promising potential for many GIS applications.
The strategic games matrix as a framework for intelligent autonomous agents hierarchical control strategies modeling

s: This paper presents a framework for strategy formulation in multilevel multiple-agent control system architectures based on the Strategic Games Matrix (SGM), having game theory and control systems theory as basic concepts and models. New methodologies for analysis and for design of hierarchical control architectures with multiple intelligent autonomous agents, based on the SGM concept, are applied. Illustrative hierarchical control applications to system architectures analysis and synthesis based on the SGM are presented.
Raman characterization of strain and composition in small-sized self-assembled Si/Ge dots

A detailed Raman characterization of the structural properties of as-grown and annealed self-assembled Si/Ge dot multilayers is reported in this paper. Several new modes in as-grown or annealed Si/Ge dots and a frequency splitting of 4.2 cm(-1) between the longitudinal (LO) and transversal optical (TO) Ge-Ge modes in as-grown Si/Ge dots are observed in Raman spectra. An average Ge content of 0.8 and lateral strain of -3.4% are consistently obtained from these spectral features for as-grown Si/Ge dots with a lateral size of about 20 nm and a height of about 2 nm. It suggests that a certain amount of intermixing between Si spacer layers and Si/Ge dots takes place for the Si/Ge dot multilayers. The annealing behavior of the Ge-Si mode in Si/Ge dots indicates that the observed sharp Ge-Si mode is a Ge-Si alloy mode within the core regions of Si/Ge dots, rather than a Ge-Si interface mode in the interface regions of dots. The phonon strain-shift coefficients of the Ge-Ge and Ge-Si modes are determined for the small-sized Si/Ge dots with a high Ge content under a biaxial strain condition. The results show that the LO-TO frequency splitting of the Ge-Ge mode and the frequencies of the Ge-Ge and Ge-Si modes can be used as an efficient way to determine the average strain and composition in uncorrelated small-sized Si/Ge dot multilayers in which the mean strain field is close to the biaxial case.
Nash equilibrium design and coordination in hierarchical systems

This paper deals with the problem of Nash equilibrium design in noncooperative games in which agents anticipate values of Lagrange multipliers (prices) coordinating their payoffs. Sufficient conditions are formulated for Nash-implementation of regular and isolated solution to conditional optimization problem with equality constraints. Nash equilibrium design procedure for price-anticipation game is proposed as well. The problem is studied within the framework of control and coordination theory for hierarchical systems. A network congestion control game is discussed as a motivating example.
Mechanical nociceptive threshold testing in Bos indicus bull calves

The aim of this prospective, controlled, randomised trial was to develop a technique for mechanical nociceptive threshold testing (NTT) to assess pain in Bos indicus bull calves undergoing surgical castration. Analgesia was provided by 0.5 mg/kg subcutaneous (SC) meloxicam (M) and/or 2 mg/kg of intra-testicular and SC (at the surgery sites) lidocaine (L). Forty-eight Brahman bull calves at 6–8 months of age were divided into six study groups, each with eight animals: no surgery control; surgical castration (C) without analgesia; C and Mpre-op; C and Mpost-op; C, L and Mpost-op; C and L. Mechanical NTT was performed the day before surgery (Day –1) and on Days 1, 2, 6, 10 and 13 after surgery. A handheld manual pneumatic device with a 1-mm (diameter) blunt pin was used to deliver a mechanical stimulus to a maximum of 27 Newtons either side of the most dorsal aspect of the sacrum. The most frequent responses to the mechanical stimulus were lifting or kicking of the leg on the same side as the stimulus (31%) and stepping away from the stimulus (24.9%). Data were analysed with a mixed effect linear model with the nociceptive threshold (NT) as the response variable and day and analgesic treatment as predictors (P < 0.05 was considered significant). For all groups, there was a trend towards decreasing NT over the study period but there were no significant differences between groups. Step down model selection with day, batch and treatment terms revealed a significant effect of day (P < 0.001) and batch (P = 0.007). Mechanical NTT for assessment of pain in Bos indicus bull calves requires further refinement to determine if this is a useful method of pain assessment.
Lithospheric structure in the Baikal–central Mongolia region from integrated geophysical‐petrological inversion of surface‐wave data and topographic elevation

Recent advances in computational petrological modeling provide accurate methods for computing seismic velocities and density within the lithospheric and sub‐lithospheric mantle, given the bulk composition, temperature, and pressure within them. Here, we test an integrated geophysical‐petrological inversion of Rayleigh‐ and Love‐wave phase‐velocity curves for fine‐scale lithospheric structure. The main parameters of the grid‐search inversion are the lithospheric and crustal thicknesses, mantle composition, and bulk density and seismic velocities within the crust. Conductive lithospheric geotherms are computed using P‐T‐dependent thermal conductivity. Radial anisotropy and seismic attenuation have a substantial effect on the results and are modeled explicitly. Surface topography provides information on the integrated density of the crust, poorly constrained by surface waves alone. Investigating parameter inter‐dependencies, we show that accurate surface‐wave data and topography can constrain robust lithospheric models. We apply the inversion to central Mongolia, south of the Baikal Rift Zone, a key area of deformation in Asia with debated lithosphere‐asthenosphere structure and rifting mechanism, and detect an 80–90 km thick lithosphere with a dense, mafic lower crust and a relatively fertile mantle composition (Mg# < 90.2). Published measurements on crustal and mantle Miocene and Pleistocene xenoliths are consistent with both the geotherms and the crustal and lithospheric mantle composition derived from our inversion. Topography can be fully accounted for by local isostasy, with no dynamic support required. The mantle structure constrained by the inversion indicates no major thermal anomalies in the shallow sub‐lithospheric mantle, consistent with passive rifting in the Baikal Rift Zone.
Object categorization via sparse representation of local features

Sparse representation has been introduced to address many recognition problems in computer vision. In this paper, we propose a new framework for object categorization based on sparse representation of local features. Unlike most of previous sparse coding based methods in object classification that only use sparse coding to extract high-level features, the proposed method incorporates sparse representation and classification into a unified framework. Therefore, it does not need a further classifier. Experimental results show that the proposed method achieved better or comparable accuracy than the well known bag-of-features representation with various classifiers.

Constraint technology for user-interface construction in ThingLab II

ThingLab II is an object-oriented constraint programming system designed specifically for interactive user interface construction and implemented in Smalltalk-80 For constraints to be effective in building user interfaces, they must not impede the responsiveness of the user interface either at run time or during construction. The necessary speed is attained in ThingLab II by making judicious tradeoffs between compilation and interpretation, and by using a fast, incremental algorithm for constraint satisfaction. The resulting system allows user interface components to be assembled, tested, and modified expediently while maintaining interactive responsiveness.
Mechanism and Molecular Determinant for Regulation of Rabbit Transient Receptor Potential Type 5 (TRPV5) Channel by Extracellular pH*

The transient receptor potential type 5 (TRPV5) channel is present in kidney and intestine and important for transepithelial (re)absorption of calcium in these tissues. We report that in whole-cell patch clamp recording extracellular acidification inhibited rabbit TRPV5 with apparent pKa ∼6.55. The two extracellular loops between the fifth and sixth transmembrane segments of TRPV5 presumably form part of the outer opening of the pore and likely are important in binding and regulation by external protons. We found that mutation of glutamate 522 to glutamine (E522Q) decreased the sensitivity of the channel to extracellular acidification. Mutations of other titratable amino acids within the two extracellular loops to non-titratable amino acids had no effect on pH sensitivity. Substitutions of aspartate or other titratable amino acids for glutamate 522 conferred an increase in pH sensitivity. The pH sensitivity mediated by glutamate 522 was independent of extracellular or intracellular Mg2+. Single channel analysis revealed that extracellular acidification reduced single channel conductance as well as open probability of the wild type channel. In contrast to wild type channel, extracellular acidification did not reduce open probability for E522Q mutant. Methanethiosulfonate reagents inhibited the activity of glutamine 522 to cysteine mutant channel with a reaction rate constant approaching that with free thiols in solution, suggesting that glutamate 522 is located on the surface of the channel. These data suggest that glutamate 522 of the rabbit TRPV5 is a “pH sensor,” and extracellular protons inhibit TRPV5 likely by altering conformation of the channel protein.
