A novel machine learning approach to the detection of identity theft in social networks based on emulated attack instances and support vector machines

The proliferation of social networks and their usage by a wide spectrum of user profiles has been specially notable in the last decade. A social network is frequently conceived as a strongly interlinked community of users, each featuring a compact neighborhood tightly and actively connected through different communication flows. This realm unleashes a rich substrate for a myriad of malicious activities aimed at unauthorizedly profiting from the user itself or from his/her social circle. This manuscript elaborates on a practical approach for the detection of identity theft in social networks, by which the credentials of a certain user are stolen and used without permission by the attacker for its own benefit. The proposed scheme detects identity thefts by exclusively analyzing connection time traces of the account being tested in a nonintrusive manner. The manuscript formulates the detection of this attack as a binary classification problem, which is tackled by means of a support vector classifier applied over features inferred from the original connection time traces of the user. Simulation results are discussed in depth toward elucidating the potentiality of the proposed system as the first step of a more involved impersonation detection framework, also relying on connectivity patterns and elements from language processing.

Calibration of a flexible high precision Power-On Reset during production test

This paper describes a Power-On Reset (POR) circuit with very accurate threshold voltage levels. These voltage levels are achieved by calibrating an on-chip programmable voltage reference during the wafer sort or final test. Two different calibration methods are proposed. One which calibrates the reference voltage of a comparator and another method which calibrates the POR threshold voltage levels itself. Not only the variation of the POR threshold voltage levels can be reduced from 90mV to 7mV, but also the absolute value can be changed.
Will the attributes of multiparametric MRI permit the creation of a new approach to therapy?

Purpose of review To explore the concept that MRI can be used to permit a new approach to therapy of localized prostate cancer. Recent findings With the development of multiparametric MRI, we can characterize cancer within the prostate, in terms of location, volume and radiological phenotype. The use of volume and location to identify candidates for focal ablative therapy is well established. The radiological phenotype of a tumour includes the vascularity and diffusion characteristics of that tumour. These characteristics may help us to develop novel interventions to target particular characteristics of a tumour. The assessment of novel interventions such as sulforaphanes found in broccoli, and common medications used for other diseases such as aspirin and metformin typically use population based studies, or repeat biopsy studies in large groups of men on active surveillance. MRI, with its accurate detection of change in visible tumour over a 6-month period, could allow rapid noninvasive assessment of a novel intervention. Summary MRI could be used to allow the rapid and efficient assessment of dietary and other interventions to identify candidates for assessment in larger studies and potentially, to identify subgroups of tumours which would be most suited to a given intervention.
La demande de la qualité de l'audit externe : Quel apport de la théorie d'agence dans le contexte tunisien ?

The purpose of this paper is to study the explanatory power of agency theory on the external audit quality demand in a Tunisian context. We use auditor reputation as a proxy for a higher audit quality. The results of panel logistic estimation on a sample of 166 firm-years show that a negative relationship is established between concentrated ownership (which measures the minority/majority shareholders agency conflict), long term leverage (a proxy of the shareholders/creditors' agency conflict) and the audit quality demand. Our study shows also, that firm size experiences a positive impact on external auditor choice. On the other hand, it seems that board of directors' independence and institutional ownership influence positively the external audit quality demand.
Implementation of full adder cells using NP-CMOS and Multi-Output logic styles in 90nm technology

In this paper we present two novel 1-bit full adder cells in dynamic logic style. NP-CMOS (Zipper) and Multi-Output structures are used to design the adder blocks. Characteristic of dynamic logic leads to higher speeds than the other standard static full adder cells. Using Tanner and 90nm CMOS technology exhibits a significant decrease in the cell delay which can result in a considerable reduction in the power-delay product (PDP). The PDP of Multi-Output design at 1.8v power supply is around 0.15 fem to joule that is 5% lower than conventional dynamic full adder cell and at least 21% lower than other static full adders.
Perspective-Taking in Communication: Representations of Others' Knowledge in Reference

We review several studies examining perspective-taking in communication. One set of studies indicates that speakers exploit the common ground they share with their addressees in creating referring expressions and that such perspective-taking improves the listener's comprehension. A second set of studies examines an element of the perspective-taking process itself: the accuracy of people's assessments of others' knowledge. We find that such estimates are both fairly accurate and biased in the direction of the perceiver's own knowledge. However, the extent of their influence on message formulation depends on the availability of feedback. We conclude that perspective-taking in communication combines prior theories about what others know with information drawn from such conversational resources as verbal and nonverbal feedback.
The JAIST Machine Translation Systems for WMT 17

We describe the JAIST phrase-based machine translation systems that participated in the news translation shared task of the WMT17. In this work, we participated in the Turkish-English translation, in which only a small amount of bilingual training data is available, so that it is an example of the low-resource setting in machine translation. In order to solve the problem, we focus on two strategies: building a bilingual corpus from comparable data and exploiting existing parallel data based on phrase pivot translation. In order to utilize the strategies to enhance machine translation on the low-resource setting most effectively, we introduce a sys-tem combining the extracted corpus, the pivot translation, and the direct training data. Experimental results showed that our combined systems signiﬁcantly improved the baseline models, which were trained on the small bilingual data.

Coating of adeno‐associated virus with reactive polymers can ablate virus tropism, enable retargeting and provide resistance to neutralising antisera

Copolymers based on poly‐[N‐(2‐hydroxypropyl) methacrylamide] (HPMA) have been used previously to enable targeted delivery of adenovirus. Here we demonstrate polymer‐coating techniques can also be used to modify and retarget adeno‐associated virus (AAV) types 5 and 8.
Structural relationships of homologous proteins as a fundamental principle in homology modeling

Protein structure prediction is based mainly on the modeling of proteins by homology to known structures; this knowledgebased approach is the most promising method to date. Although it is used in the whole area of protein research, no general rules concerning the quality and applicability of concepts and procedures used in homology modeling have been put forward yet. Therefore, the main goal of the present work is to provide tools for the assessment of accuracy of modeling at a given level of sequence homology. A large set of known structures from different conformational and functional classes, but various degrees of homology was selected. Pairwise structure superpositions were performed. Starting with the definition of the structurally conserved regions and determination of topologically correct sequence alignments, we correlated geometrical properties with sequence homology (defined by the 250 PAM Dayhoff Matrix) and identity. It is shown that both the topological differences of the protein backbones and the relative positions of corresponding side chains diverge with decreasing sequence identity. Below 50% identity, the deviation in regions that are structurally not conserved continually increases, thus implying that with decreasing sequence identity modeling has to take into account more and more structurally diverging loop regions that are difficult to predict. © 1993 Wiley‐Liss, Inc.

Monocularly Induced 2‐Deoxyglucose Patterns in the Visual Cortex and Lateral Geniculate Nucleus of the Cat: I. Anaesthetized and Paralysed Animals

Extending previous investigations of the topographic relationship between ocular dominance and orientation columns in the cat visual cortex the two systems were visualized with transneuronally transported [3H]proline and with activity‐dependent uptake of [14C]2‐deoxyglucose, respectively. In addition, we used the 2‐deoxyglucose method for a functional assay of both columnar systems. To this end, cats were injected with [3H]proline in the right eye. Two weeks later, they were stimulated monocularly through this eye by presenting contours of only a single orientation in the left and contours of many different orientations in the right visual hemifield while 2‐deoxyglucose was injected. The patterns of increased 2‐deoxyglucose uptake and of terminal labelling were analysed in flat‐mount sections of the visual cortices and in frontal sections of the lateral geniculate nuclei. In the lateral geniculate nucleus, regions of increased 2‐deoxyglucose uptake are in register with the [3H]proline‐labelled laminae of the open eye. In the visual cortex, the hemispheres stimulated with many different orientations showed a rather homogeneous accumulation of 2‐deoxyglucose over the entire extent and throughout all layers of area 17. The hemispheres stimulated with a single orientation displayed columnar patterns of orientation domains essentially similar to those obtained with binocular presentation of a single orientation. In particular and despite monocular stimulation, regions of increased 2‐deoxyglucose uptake were neither in register with the [3H]proline‐labelled terminals of the stimulated eye in layer IV nor confined to columns of neural tissue above and below these terminals. The maximal horizontal offset between the termination sites of thalamic afferents and activated orientation columns was in the order of 400 μm. These findings suggest several conclusions. (i) In the cat visual cortex, binocular convergence seems to occur so early in cortical processing that monocular stimulation with many orientations leads to a rather homogeneous activation of cortical tissue. (ii) From the termination zones of geniculate afferents activity is apparently distributed already within layer IV to the respective orientation columns. (iii) This horizontal spread of activity could be assured by target cells with radially extending dendrites and/or tangentially oriented fibres.
Autologous blood injection in the treatment of lateral epicondylitis.

OBJECTIVE To determine mean decrease in visual analogue pain score after autologous blood injection in patients with lateral epicondylitis. METHODS The quasi-experimental study was conducted at Ghurki Trust Hospital, Lahore, from December 10, 2012, to June 8, 2013, and comprised patients having lateral epicondylitis of elbow. Pre-procedure baseline visual analogue score was measured. Under aseptic conditions, 2ml of autologous blood was drawn from the contra-lateral antecubital fossa of the patient and slowly injected into the site of maximum tenderness. Patients were advised to continue their normal daily activities and were followed up at third and sixth week for assessment of pain intensity. Mean decrease was calculated by subtracting the post-procedure visual analogue score from the baseline value.SPSS 11 was used for data analysis. RESULTS Of the 150 patients in the study, there were 127(84.7%) males and 23(15.3%) females. Male-to-female ratio was 5.5:1 Overall mean age of was 33.91±10.23 years. The mean pre-injection pain score was 8.97±1.02 and post-injection was 3.59±1.58. Mean decrease in VAS pain score was 5.37±1.80. CONCLUSIONS Autolgous blood injection was found to be an effective way to treat patients of epicondylitis elbow.
[Correlation between refraction and ocular biometry].

PURPOSE To study the correlation between subjective refraction and biometry obtained by Orbscan and echography in normal eyes. To compare biometric parameters with the subjective spherical equivalent. MATERIAL AND METHODS Subjective refraction, biometric parameters using Orbscan, and echography were recorded in 190 normal eyes (including eyes with ametropia) of 95 patients. Biometric parameters (i.e., corneal diameter, anterior chamber depth, central pachymetry, iridocorneal angle, corneal and lens radii of curvature, and axial length of the eye) were compared in different refractive groups and were correlated with the subjective refraction. RESULTS Corneal biometric parameters did not correlate with the subjective spherical equivalent and showed no differences between the refractive groups except for the central pachymetry. In the high myopic group (<-6D), the central cornea was significantly thinner (531 micro m versus 549 micro m, p=0.016). The correlation between corneal radius and axial length was strong in emmetropic eyes (r(s)=0.63, p<0.001) and poor but significant in ametropic eyes (r(s)=0.28, p=0.002). Axial length, anterior chamber depth, and iridocorneal angle showed significant differences between the refractive groups (p<0.001) and correlated with the subjective spherical equivalent (r(s[[/INF=0.44, p<0.001). Subjective spherical equivalent showed the strongest correlation with the axial length (rs)=0.82, p<0.001). Subjective spherical equivalent, central corneal thickness, axial length, anterior chamber depth, and anterior corneal radius showed a strong correlation between both eyes (rs[[/INF=0.94, p<0.001). CONCLUSION Biometric characteristics of the eye (excluding cornea characteristics) vary with subjective spherical equivalent. Axial length presents the strongest correlation with the subjective spherical equivalent and correlates with the other ocular biometric parameters. Axial length plays a major role in the ocular biometry and refraction.
Privacy preservation in SMAC-social networking, mobile network, analytics and cloud computing

SMAC-Social Networking, Mobile Network, Analytics and Cloud Computing, is the latest buzz word in many established and upcoming organizations. Social Networking refers to an individual centered online portal to share personal profiles, preferences and make new friends or connections. The era of smartphones began a decade back but now it is at its peak with mobility and mobile networks a major part of every individual's life, thanks to the advancements in wireless technologies, mobile computing and usability engineering. Big Data and Analytics is a domain prevalent due to the large quantity of unstructured data generated on a day to day basis from which patterns are recognized, trends are known, forecasting is possible, user behavior is predicted and much more. Cloud Computing techniques elaborate the ways in which data can be stored and retrieved from a centralized location especially when the location is provided as a service to the user. Though the concepts, working procedure, target audience and need of each of the domains in SMAC is different, the challenge remains constant-Privacy preservation. This paper identifies the major challenges of privacy preservation and summarizes the techniques used, with pros and cons, in each domain.
NT-proBNP and the risk of incident hypertension: is change over time a better predictor than baseline value?

I n many different areas of cardiovascular physiology [1], cardiac biomarkers have been shown to be very useful tools in evaluating cardiac (dys)function [2], assessing diagnosis [3,4], guiding subsequent management [5], stratifying prognosis [6], as well as assessing total cardiovascular risk [7]. Moreover, they significantly contribute to our knowledge of mechanisms of disease genesis and progression. In this area, the release of natriuretic peptides has been extensively studied in the past decades, and B-type natriuretic peptide (BNP) has been defined as a ‘window’ to the cardiovascular system [8], able to help clinicians in diagnosis, follow-up, and prognostication [9–11]. This is the case not only for heart failure [12,13] but also for specific cardiac diseases, such as amyloid cardiomyopathy [14–17], congenital heart disease [18], hypertrophic cardiomyopathy [19], pulmonary embolism [20], and many other conditions [21]. In the setting of arterial hypertension, the role of natriuretic peptides is complex. On the one hand, a higher serum concentration of BNP is a rather robust marker of pressureinduced cardiac damage [22], on the one hand a reduced risk of hypertension has been associated with genetically elevated concentrations of either BNP or the N-terminal fragment of proBNP (NT-proBNP) [23,24]. Among many others, the main effects of BNP are vasodilation as well as natriuresis, both representing key mechanisms in arterial pressure control and in the cardio-renal cross-talk. Opposite effects are exerted by the renin–angiotensin–aldosterone system, and it has been recently shown that natriuretic peptides buffer renal vascular hypertension via reninindependent effects [25]. BNP is released by ventricular
Profiling Price Dynamics in Online Auctions Using Curve Clustering

Electronic commerce, and in particular online auctions, have received an extreme surge of popularity in recent years. While auction theory has been studied for a long time from a game-theory perspective, the electronic implementation of the auction mechanism poses new and challenging research questions. In this work, we focus on the price formation process and its dynamics. We present a new source of rich auction data and introduce an innovative way of modelling and analyzing price dynamics. We represent auctions as functional objects by accommodating the special structure of bidding data. We then use functional data analysis to characterize different types of auctions. Our findings suggest that there are several types of dynamics even for auctions of comparable items. By profiling these differences with respect to features associated with the auction format, the seller and the winner we find new relationships between dynamics and auction settings, and we tie these findings to the existing literature on online auctions.
Capacity Management: Intra-Firm and Inter-Firm Perspectives.

Capacity Management: Intra-Firm and Inter-Firm Perspectives by Anyan Qi Co-Chairs: Hyun-Soo Ahn and Amitabh Sinha Capacity management is challenging. Many decisions regarding capacity are made before full information is known, often requiring large and irrevocable expenditures. Moreover, the consequences of wrong capacity decisions critically affect the firm’s bottom line. In recent years, the capacity decision has become of particular interest, reflecting two principal trends. First, advances in information technology that provide huge amounts of data about operations and demand offer firms potential to utilize this big data in making capacity decisions. Second, although supply chains today are highly decentralized with complex topologies, many buying firms and suppliers aim to maintain tight relationships with initiatives such as supplier development, among which capacity investment is an important strategic decision. Corresponding to the two streams, we analyze a firm’s capacity management decision, how much capacity a firm should have and why, at both intra-firm and inter-firm levels. At the intra-firm level, we investigate how a firm should learn demand information and leverage the information in capacity decisions. In Chapter II, we formulate a firm’s capacity adjustment plan when the demand distribution is unknown as a stochastic dynamic program, and derive the optimal policy and date-driven heuristics. xii At the inter-firm level, using game theory, we examine how a firm should manage its capacity at a shared supplier given two contractual constraints: exclusive, where other firms cannot access the leftover, and first-priority, where they can. In Chapter III where firms compete and the capacity cost consists of a fixed and a variable portion, we find that firms tend to invest more aggressively under the exclusive contract. Therefore, sometimes the firm may benefit from letting a competitor free-ride on the invested capacity. In Chapter IV where firms may or may not compete and the capacity cost has a variable portion, we characterize two equilibria: a prisoner’s dilemma, where both firms choose the exclusive capacity which is not Pareto-optimal, and a free-rider equilibrium, where one firm chooses the first-priority capacity and allows the other with exclusive capacity to free ride. Both equilibria can be sustained when the firms serve independent markets, but not when they compete in a Cournot market.
