There are several well known techniques to observe criminal activities on the monitoring its traffic. One option consists in using global telescopes or dark offer interesting views of global trends. Another solution consists in centralizin logs and intrusion detection system alerts to extract some information. In this advocate the usefulness of a third approach that focuses on the need of local v more precise information on some attacks. With this idea in mind, we have and deployed for the last six months a distributed honeypot environment distinct countries. We show in this paper that 1) local sensors pre to a cert we demonstrate the usefulness of distributed honeypots and we hope to Honeypots, distributed
Performance gains using subpages for cache coherency control

When implementing a shared disk database management system, one of the major problems is how to realize an efficient cache coherency mechanism. Most of the solutions proposed use pages as the granularity for concurrency and coherency control. Under high data contention this granularity is not capable of achieving the scalability goal. We describe a new approach called Virtual DataBase Cache, that maintains concurrency control and cache coherency at subpage level in order to reduce data contention. VDBC allows multiple readers and multiple writers concurrently on a page. It also supports different subpage sizes for different tables resp. segments. Our extensive performance analysis, which is presented, clearly shows that our approach is superior to a page based method.
Robotic flowshop scheduling is strongly NP-complete

We consider a robotic flowshop model in which a single robot is responsible for the transportation of parts between machines and the amount of time that a part spends on a machine must be comprised in some predefined interval. The objective is to find a feasible schedule with minimal cycle time. Many researchers have proposed nonpolynomial solution methods for a variety of closely related robotic flowshop scheduling problems. This paper provides a proof that a basic version of this problem is strongly NP-Complete.

Commit guru: analytics and risk prediction of software commits

Software quality is one of the most important research sub-areas of software engineering. Hence, a plethora of research has focused on the prediction of software quality. Much of the software analytics and prediction work has proposed metrics, models and novel approaches that can predict quality with high levels of accuracy. However, adoption of such techniques remain low; one of the reasons for this low adoption of the current analytics and prediction technique is the lack of actionable and publicly available tools. We present Commit Guru, a language agnostic analytics and prediction tool that identifies and predicts risky software commits. Commit Guru is publicly available and is able to mine any GIT SCM repository. Analytics are generated at both, the project and commit levels. In addition, Commit Guru automatically identifies risky (i.e., bug-inducing) commits and builds a prediction model that assess the likelihood of a recent commit introducing a bug in the future. Finally, to facilitate future research in the area, users of Commit Guru can download the data for any project that is processed by Commit Guru with a single click. Several large open source projects have been successfully processed using Commit Guru. Commit Guru is available online at commit.guru. Our source code is also released freely under the MIT license.
The Association of Knowledge with Concern About Global Warming: Trusted Information Sources Shape Public Thinking

During the last decade, a great deal of news media attention has focused on informing the American public about scientific findings on global warming (GW). Has learning this sort of information led the American public to become more concerned about GW? Using data from two surveys of nationally representative samples of American adults, this article shows that the relation between self‐reported knowledge and concern about GW is more complex than what previous research has suggested. Among people who trust scientists to provide reliable information about the environment and among Democrats and Independents, increased knowledge has been associated with increased concern. But among people who are skeptical about scientists and among Republicans more knowledge was generally not associated with greater concern. The association of knowledge with concern among Democrats and Independents who trust scientists was mediated by perceptions of consensus among scientists about GW's existence and by perceptions that humans are a principal cause of GW. Moreover, additional analyses of panel survey data produced findings consistent with the notion that more knowledge yields more concern among Democrats and Independents, but not among Republicans. Thus, when studying the relation of knowledge and concern, it is important to take into account the content of the information that different types of people acquire and choose to rely upon.
Flare, Persistently Active Disease, and Serologically Active Clinically Quiescent Disease in Systemic Lupus Erythematosus: A 2-Year Follow-Up Study

Objective Several indices have been proposed to assess disease activity in patients with Systemic Lupus Erythematosus (SLE). Recent studies have showed a prevalence of flare between 28–35.3%, persistently active disease (PAD) between 46%–52% and serologically active clinically quiescent (SACQ) disease ranging from 6 to 15%. Our goal was to evaluate the flare, PAD and SACQ rate incidence in a cohort of SLE patients over a 2-year follow-up. Methods We evaluated 394 SLE patients. Flare was defined as an increase in SLEDAI-2K score of ≥4 from the previous visit; PAD was defined as a SLEDAI-2K score of ≥4, on >2 consecutive visits; SACQ was defined as at least a 2-year period without clinical activity and with persistent serologic activity. Results Among the 95 patients eligible for the analysis in 2009, 7 (7.3%) had ≥1 flare episode, whereas 9 (9.4%) had PAD. Similarly, among the 118 patients selected for the analysis in 2010, 6 (5%) had ≥1 flare episode, whereas 16 (13.5%) had PAD. Only 1/45 patient (2.2%) showed SACQ during the follow-up. Conclusion We showed a low incidence of flare, PAD and SACQ in Italian SLE patients compared with previous studies which could be partly explained by ethnic differences.
Analysis of MIMO Systems used in planning a 4G-WiMAX Network in Ghana

with the increasing demand for mobile data services, Broadband Wireless Access (BWA) is emerging as one of the fastest growing areas within mobile communications. Innovative wireless communication systems, such as WiMAX, are expected to offer highly reliable broadband radio access in order to meet the increasing demands of emerging high speed data and multimedia services. In Ghana, deployment of WiMAX technology has recently begun. Planning these high capacity networks in the presence of multiple interferences in order to achieve the aim of enabling users enjoy cheap and reliable internet services is a critical design issue. This paper has used a deterministic approach for simulating the Bit-Error-Rate (BER) of initial MIMO antenna configurations which were considered in deploying a high capacity 4G-WiMAX network in Ghana. The radiation pattern of the antenna used in the deploying the network has been simulated with Genex-Unet and NEC and results presented. An adaptive 4x4 MIMO antenna configuration with optimally suppressed sidelobes has been suggested for future network deployment since the adaptive 2x2 MIMO antenna configuration, which was used in the initial network deployment provides poor estimates for average BER performance as compared to 4x4 antenna configuration which seem less affected in the presence of multiple interferers.
ABSOLUTE PROPERTIES OF THE ECLIPSING BINARY STAR HY VIRGINIS

HY Vir is found to be a double-lined F0m+F5 binary star with relatively shallow (0.3 mag) partial eclipses. Previous studies of the system are improved with 7509 differential photometric observations from the URSA WebScope and 8862 from the NFO WebScope, and 68 high-resolution spectroscopic observations from the Tennessee State University 2 m automatic spectroscopic telescope, and the 1 m coudé-feed spectrometer at Kitt Peak National Observatory. Very accurate (better than 0.5%) masses and radii are determined from analysis of the new light curves and radial velocity curves. Theoretical models match the absolute properties of the stars at an age of about 1.35 Gy.
Title Effects of cultural and linguistic backgrounds on perceptualvoice quality rating Other

Perceptual voice judgment is a standard procedure in voice quality evaluation. However, the cultural and linguistic backgrounds of the judges often affect its reliability. Use of anchors has been shown to improve the reliability of the procedure. Therefore, this study aimed to develop female synthesized anchors in Cantonese, English, and Putonghua and investigate the reliability of perceptual voice rating across speakers of three native languages using an anchor-matching method. Ten native Cantonese speakers, 10 native English speakers and 10 native Putonghua speakers were recruited to rate the severity of breathiness and roughness of pathological voice samples in Cantonese, English and Putonghua. Results showed high intra-rater agreement (average 87.23%) and inter-rater reliability (average 0.94) across listener groups and stimuli sets. The Putonghua listeners in this study demonstrated significantly lower intra-rater agreement than the Cantonese listeners, suggesting possible cultural and linguistic differences in perceptual voice evaluation between Putonghua and Cantonese listeners.
Use of BACTEC MGIT 960 for Recovery of Mycobacteria from Clinical Specimens: Multicenter Study

ABSTRACT The BACTEC MGIT 960 instrument is a fully automated system that exploits the fluorescence of an oxygen sensor to detect growth of mycobacteria in culture. Its performance was compared to those of the radiometric BACTEC 460 instrument and egg-based Lowenstein-Jensen medium. An identical volume of sample was inoculated in different media, and incubation was carried out for 6 weeks with the automatic systems and for 8 weeks on solid media. A total of 2,567 specimens obtained from 1,631 patients were cultured in parallel. Mycobacteria belonging to nine different taxa were isolated by at least one of the culture systems, with 75% of them being represented byMycobacterium tuberculosis complex. The best yield was obtained with the BACTEC 460 system, with 201 isolates, in comparison with 190 isolates with the BACTEC MGIT 960 system and 168 isolates with Lowenstein-Jensen medium. A similar but not significant difference was obtained when the most-represented organisms, the M. tuberculosis complex, Mycobacterium xenopi, and theMycobacterium avium complex, were analyzed separately and when combinations of a solid medium with the BACTEC MGIT 960 system and with the BACTEC 460 system were considered. The shortest times to detection were obtained with the BACTEC MGIT 960 system (13.3 days); 1.5 days earlier than that with the BACTEC 460 system (14.8 days) and 12 days earlier than that with Lowenstein-Jensen medium (25.6 days). The BACTEC MGIT 960 system had a contamination rate of 10.0%, intermediate between those of the radiometric system (3.7%) and the egg-based medium (17.0%). We conclude, therefore, that the BACTEC MGIT 960 system is a fully automated, nonradiometric instrument that is suitable for the detection of growth of tuberculous and other mycobacterial species and that is characterized by detection times that are even shorter than that of the “gold standard,” the BACTEC 460 system. The contamination rate was higher than that for the radiometric BACTEC 460 system and needs to be improved.
A method for analysis of gene expression in isolated mouse photoreceptor and Müller cells.

PURPOSE Molecular analysis of complex phenomena, such as selective death of photoreceptors and their rescue by neuro-protective agents, has been hindered by limitations of techniques for investigating gene expression in individual cells within a heterogeneous tissue such as the retina. The purpose of this study was to develop methods to assess gene expression in single retinal cells. METHODS Individual cells from papain-dissociated mouse retinae were captured with micropipettes and identified by morphology and by immunocytochemistry. Single cell cDNA libraries were generated by poly-d(T)-primed reverse transcription, poly-d(A) tailing of first strand cDNA, and en masse PCR-amplification using a custom made oligo-d(T). PCR was used to investigate gene expression in cDNAs from individual cells. RESULTS Dissociated rod and Müller glia cells maintained their morphology, which correlated with their immunocytochemical properties. RPE cells were recognized by their pigmentation. With the exception of bipolar cells, non-photoreceptor neurons were only identifiable by immunocytochemistry. Abundant cDNA could be synthesized from each individual cell. Cell-specific "markers" were detected by PCR almost exclusively in the predicted cell types. The expression of neurotrophic factor receptors was consistent with previous biological studies. CONCLUSIONS These studies establish a method to compare, investigate, and analyze gene expression in individual cells of the retina.
Minimizing Communication Cost for Reconfigurable Slot Modules

We discuss the problem of communication-aware module placement in array-like reconfigurable environments, such as the Erlangen Slot Machine (ESM). Bad placement of modules may degrade performance due to increased signal delays and wastes chip space for the reconfigurable multiple bus. We present integer linear programming (ILP) formulations that address both of these problems; both ILPs can be used stand-alone or as building blocks for more involved mathematical models. We validate our models by demonstrating their usefulness for a set of realistic benchmarks.
On improving approximate solutions by evolutionary algorithms

Hybrid methods are very popular for solving problems from combinatorial optimization. In contrast to this the theoretical understanding of the interplay of different optimization methods is rare. The aim of this paper is to make a first step into the rigorous analysis of such combinations for combinatorial optimization problems. The subject of our analyses is the vertex cover problem for which several approximation algorithms have been proposed. We point out specific instances where solutions can (or cannot) be improved by the search process of a simple evolutionary algorithm in expected polynomial time.
A dual three-leg VSI based DSTATCOM in three-phase four-wire distribution systems

This paper proposes a dual three-leg voltage source inverter (VSI) based distribution static compensator (DSTAT-COM) to compensate unbalanced and nonlinear loads in three-phase four-wire distribution systems. The proposed topology uses two three-leg inverters having common dc-link with single dc capacitor and an additional small capacitor connected from the negative terminal of VSI to the system neutral. The proposed scheme with associated control algorithm has the capability to compensate unbalanced nonlinear load and hence makes source current as balanced sinusoidal and at desired power factor. The control algorithm also ensures the proper sharing of reactive, harmonics and unbalance powers between two VSIs and controls the grid current total harmonic distortion (THD) level. The performance of the proposed scheme has been verified using simulation and experimental studies and results are presented.
Speed Enhancement and Linearity Analysis for a Rail-to-Rail Input Opamp in 120nm CMOS

This paper introduces a fully differential opamp with constant large-and small-signal behavior rail-to-rail input stage. A compensation strategy is presented to extend the bandwidth. The linearity issue of the compensation is discussed. A test chip is implemented in a standard 120 nm CMOS process, with the measured signal variation of about 4.43% as well as a GBW of 135 MHz. Experimental results verify the performance.
On nonstandard labour values, Marx’s transformation problem and Ricardo’s problem of an invariable measure of value

This essay is a critique of the classical labour theory of value when translated into the modern form of linear production theory. In many respects, the modern translation is an accurate and precise depiction of the deep conceptual structure of the classical theory; in some other respects it is not. Nonetheless the modern translation reproduces and clarifies two fundamental problems of the classical labour theory of value: Marx’s ‘transformation problem’ (the contradiction between the law of value and uniform profits) and Ricardo’s problem of an invariable measure of value (the lack of an objective ‘measuring rod’ to ground inter-temporal value comparisons). The argument of this essay is that both problems derive from the same conceptual error, specifically the failure to properly specify replacement costs for a capitalist economy. The transformation problem and the problem of an invariable measure of value are both symptoms of this underlying labour-cost accounting error.
PROVIDING SECURITY WITH CAPTCHA AS GRAPHICAL PASSWORDS

— There are many security primitives that are based on hard mathematical problems. Using hard AI problems for security is emerging as an exciting new paradigm, but this solution has been under-explored. In this paper, we present a new security primitive based on hard AI problems which is a novel family of graphical password systems built on top of Captcha technology. This technology we call as Captcha as graphical passwords (CaRP). CaRP is both a Captcha and a graphical password scheme. The graphical-password approach is sometimes called as graphical user authentication(GUA). CaRP addresses a number of security problems altogether, such as online guessing attacks, relay attacks. If CaRP is combined with dual-view technologies, shoulder-surfing attacks are addressed. Notably, even if the CaRP password is in the search set it can be found only probabilistically by automatic online guessing attacks. CaRP also offers a novel approach to address the well-known image hotspot problem in popular graphical password systems, such as PassPoints, that often leads to weak password choices. CaRP is not a panacea, but it offers reasonable security and usability and appears to fit well with some practical applications for improving online security.

Auditory Frequency Threshold and Signal Detection Theory

Human auditory perception is a phenomenon that relies on the detection of various frequencies in environmental sound waves. The range for detecting a sound wave frequency varies amongst individuals, but is typically 20-20,000 Hz. The purpose of this study was to measure an individual’s absolute threshold to an auditory stimulus via two methods: the constant stimuli method and the signal detection theory method. In part 1, the participant was asked to listen to a whistle at five different frequencies and state whether or not they detected the sound. For part 2, they were presented either with no stimulus or with the stimulus and were asked to state whether or not they detected the sound. The individual’s measured absolute threshold was 301 Hz with a sensitivity of 2.32 and a criterion of 1.27. Thus, this individual was fairly sensitive to the signal and had a bias to say “no”. In conclusion, it was the signal detection theory that could determine the true perceptual ability because it allowed for the estimation of response biases.
ARGUING THE NEED FOR QUALITATIVE EXPLORATION IN THE FIELD OF EMERGING DIGITAL PATHOLOGIES

Little has been done globally to ethnographically (and holistically) study and understand the lives of heavy Internet users, with insufficient qualitative research (that is, exploratory, descriptive, inductive) published throughout the world. This article presents the findings from qualitative semi-structured interviews with five psychologists, who were asked about their understanding of addiction and Problematic Internet Use. The findings demonstrate the complexity of the field and the possibility of co-morbidity, suggesting that so-called “Internet abuse” or multiple derivatives of the label are inaccurate and unhelpful. In-depth qualitative research is needed to add depth and insight to this highly topical area, where a myriad of scales are being put forward, tested and validated from one hegemonic paradigm within this field. Further nuanced understandings of Internet use need to be developed to work towards constructing theories and pedagogies that help to understand and address digital pathologies successfully.
Decay of trapped ultracold alkali atoms by recombination.

Using the knowledge of two-body collision properties that has recently become available, we estimate the three-body recombination rate for doubly-spin-polarized ultracold gas samples of $^{7}\mathrm{Li}$, $^{23}\mathrm{Na}$ and $^{87}\mathrm{Rb}$ on the basis of the Jastrow approximation. We find that only recombination leading to the formation of the highest two-body bound states is important. The rate for the highest bound level with zero angular momentum is found to increase strongly with the absolute value of the two-body scattering length. \textcopyright{} 1996 The American Physical Society.
