On calibrating enterprise switch measurements

The complexity of modern enterprise networks is ever-increasing, and our understanding of these important networks is not keeping pace. Our insight into intra-subnet traffic (staying within a single LAN) is particularly limited, due to the widespread use of Ethernet switches that preclude ready LAN-wide monitoring. We have recently undertaken an approach to obtaining extensive intra-subnet visibility based on tapping sets of Ethernet switch ports simultaneously. However, doing so leads to a number of measurement calibration issues that require careful consideration to address. First, one must correctly account for redundant copies of packets that appear due to switch flooding, which if not accurately identified can greatly skew subsequent analysis results. We show that a simple, natural rule one might use for doing so in fact introduces systematic errors, but an altered version of the rule performs significantly better. We then employ this revised rule to aid with calibration issues concerning the fidelity of packet timestamps and the amount of measurement loss that our collection apparatus incurred. Additionally, we develop techniques to "map" the monitored network in terms of identifying key topological components, such as subnet boundaries, which hosts were directly monitored, and the presence of "hidden" switches and hubs. Finally, we present initial analyses demonstrating that the magnitude and diversity of traffic at the subnet level is in fact striking, highlighting the importance of obtaining and correctly calibrating switch-level enterprise traces.
The effect of CO60 on the physical and physicochemical properties of rice

O arroz apresenta composicao quimica e cadeia produtiva susceptiveis a contaminacao por fungos. Entre outras tecnicas, a aplicacao de radiacao gama tem sido sugerida como um metodo para assegurar a seguranca dos alimentos. No entanto, esta radiacao pode alterar a composicao quimica do alimento. Assim, o objetivo do presente trabalho foi avaliar a composicao centesimal, o valor calorico, o pH, a acidez titulavel total e a coloracao do arroz branco polido submetido a diferentes doses de radiacao gama Co60 (0 kGy, 6,5 kGy e 7,5 kGy). Os resultados demonstraram que a irradiacao gama nao promoveu alteracoes significativas na composicao centesimal, valor calorico e acidez titulavel do arroz, porem foi substancial para promover uma diminuicao do pH e intensificacao da coloracao, a medida que se aumentavam as doses. Sob condicoes controladas de irradiacao, a dose de 6,5 kGy, pode tornar o arroz seguro para o consumo sem comprometer significativamente suas propriedades fisicas e fisico-quimica.
Modeling of a rotor/fixed-wing hybrid unmanned aerial vehicle

In this paper, it is discussed the modeling problem of a rotor/fixed-wing hybrid unmanned aerial vehicle (UAV). The vehicle has two main advantage functions, i.e., fixed-wing cruise and vertical take-off and landing (VTOL). This paper focuses on analysis of the transition process for the rotor/fixed-wing hybrid UAV, which consists of four stages. Based on the six degree of freedom model, the modeling algorithm of the rotor/fixed-wing hybrid UAV is proposed.
Portuguese version of the Quality of Life Enjoyment and Satisfaction Questionnaire: a validation study.

OBJECTIVE The aim of this study was to demonstrate the validity and reliability of the Portuguese version of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) among substance users in southern Brazil. METHODS The original English version of the Q-LES-Q was translated into Portuguese taking into account semantic and conceptual equivalence. The Portuguese versions of the Q-LES-Q and the World Health Organization Quality of Life Instrument (WHOQOL-BREF) were used to assess quality of life among crack cocaine and inhalant users. Factorial and reliability analyses as well as correlation studies were conducted to establish the psychometric properties of the Portuguese version of the Q-LES-Q. RESULTS All areas of the Q-LES-Q achieved significant Cronbach's coefficients. Significant Pearson correlation coefficients were obtained between various subscales of the Q-LES-Q and the four dimensions of the WHOQOL-BREF. Correlations were significant when crack and inhalant users were analyzed separately or conjointly. Inhalant users presented significantly higher scores than crack users in the social (p=0.035) and general (p=0.005) subscales of the Q-LES-Q. CONCLUSION The Portuguese version of the Q-LES-Q possesses sound internal validity. The English version of the Q-LES-Q was adequately adapted to Portuguese. Inhalant users may present lower levels of satisfaction with social life and overall quality of life than crack users. The Portuguese version of the Q-LES-Q is a reliable questionnaire for future research and clinical use with substance users in Brazil.
Six In Vivo Assessments of Compulsive Behavior: A Validation Study Using the Obsessive–Compulsive Inventory–Revised

Due to the complex and heterogeneous nature of obsessive–compulsive disorder (OCD), movement toward multimodal assessment has become necessary to more precisely understand the nature of the disorder and interrelations between symptom clusters. Thus, the present study utilized large undergraduate samples (total N = 800) to test the validity of six in vivo assessments of OC symptoms (i.e., one ordering/arranging task, two contamination fear/washing tasks, and three checking tasks). Associations between task-specific variables and self-reported symptom scores (as measured by the Obsessive–Compulsive Inventory–Revised [OCI-R]) were examined. The majority of the in vivo task variables (those presented in Studies 1-4) exhibited significant relationships with the corresponding OCI-R symptom subscale (i.e., ordering, washing, checking). However, many of the task variables demonstrated relationships with other OCI-R symptom subscales, as well. Some evidence for discriminant validity was found, as task variables were generally unrelated to past-week symptoms of depression or anxiety. While continued research is necessary to further establish the validity and utility of the tasks discussed in the current article, findings have implications for improving future empirical examination of OC symptoms.
Nonlinear acoustic echo cancellation with 2nd order adaptive Volterra filters

Acoustic echo cancellers in today's speakerphones or video conferencing systems rely on the assumption of a linear echo path. Low-cost audio equipment or constraints of portable communication systems cause nonlinear distortions, which limit the echo return loss enhancement achievable by linear adaptation schemes. These distortions are a super-position of different effects, which can be modelled either as memoryless nonlinearities or as nonlinear systems with memory. Proper adaptation schemes for both cases of nonlinearities are discussed. An echo canceller for nonlinear systems with memory based on an adaptive second order Volterra filter is presented. Its performance is demonstrated by measurements with small loudspeakers. The results show an improvement in the echo return loss enhancement of 7 dB over a conventional linear adaptive filter. The additional computational requirement for the presented Volterra filter is comparable to that of existing acoustic echo cancellers.
Title Dynamics of Spectro-Temporal Tuning in Primary Auditory Cortex of the Ferret

In this paper, we explore spectro-temporal tuning in primary auditory cortex following a sudden change in spectro-temporal content. We previously characterized the steady-state spectrotemporal tuning properties of cortical cells with respect to broadband sounds by presenting sounds with a spectro-temporal envelope of constant spectral density and angular frequency for several seconds. However, since speech and other natural sounds have spectro-temporal features that change substantially over milliseconds, we studied the dynamics of tuning by using stimuli of constant level but alternating between a flat spectro-temporal envelope and a modulated envelope with well defined spectral density and angular frequency. This allowed us to define the tuning of cortical cells to speech-like and other rapid transitions, at the order of milliseconds, as well as the time evolution of this tuning in response to the features of a new sound. We find that cortical neurons can be characterized by a lag-dependent modulation transfer function. This characterization, when measured through to steady-state, is equivalent to the classical spectrotemporal receptive field.

Dietary Mushroom Intake May Reduce the Risk of Breast Cancer: Evidence from a Meta-Analysis of Observational Studies

Epidemiological studies have investigated the potential anticancer effects of mushroom intake. This review aims to clarify the evidence on the association of dietary mushroom intake with breast cancer risk and to quantify its dose-response relationship. Relevant studies were identified by a search of PubMed, Web of Science and Google Scholar up to December 31, 2013. Observational studies with relative risks (RRs) or hazard ratios (HRs) or odd ratios (ORs) and 95% confidence intervals (CIs) of breast cancer for three or more categories of mushroom intake were eligible. The quality of included studies was assessed by using Newcastle-Ottawa Scale. A dose-response meta-analysis was performed by utilizing generalized least squares trend estimation. Eight case-control studies and two cohort studies with a total of 6890 cases were ultimately included. For dose-response analysis, there was no evidence of non-linear association between mushroom consumption and breast cancer risk (P = 0.337) and a 1 g/d increment in mushroom intake conferred an RR of 0.97 (95% CI: 0.96–0.98) for breast cancer risk, with moderate heterogeneity (I2 = 56.3%, P = 0.015). Besides, available menopause data extracted from included studies were used to evaluate the influence of menopausal statues. The summary RRs of mushroom consumption on breast cancer were 0.96 (95% CI: 0.91–1.00) for premenopausal women and 0.94 (95% CI: 0.91–0.97) for postmenopausal women, respectively. Our findings demonstrated that mushroom intake may be inversely associated with risk of breast cancer, which need to be confirmed with large-scale prospective studies further.
A Variation Aware High Level Synthesis Framework

The worst-case delay/power of function units has been used in traditional high level synthesis to facilitate design space exploration. As technology scales to nanometer regime, the impact of process variations increases. The degree of variability encountered in the new process technologies makes worst-case analysis undesirable, because it may result in unexpected performance/power discrepancy or a pessimistic estimation, and may end up using excess resources to guarantee design constraints. In this paper, we propose a high level synthesis framework to take into account of the performance/power variation for function units. An effective metric called parametric yield, which is defined as the probability of the synthesized data flow graph (DFG) meeting the performance and power constraints, is used to guide scheduling, module selection, and resource sharing. An efficient performance/power yield perturbation computation method for DFG significantly improves the effectiveness of our yield driven high level synthesis algorithm. The experimental results show that our variation-aware synthesis framework achieves significant yield improvements, and has much faster (3X) runtime speed compared against previous approach.
Uncovering Malingered Amnesia

One approach to the discovery of malingered amnesia is to exploit the fact that true amnesics can learn and remember under some conditions and can display their knowledge when appropriately tested. In particular, patients with organic amnesia of several etiologies can recognize previously presented but unrecalled words at much higher than chance rates. ’,’ Recognition better than free recall is also characteristic of posthypnotic amnesia’ and normal memory degraded by long delays! Thus, these phenomena appear to be general characteristics of memory loss and are not restricted to brain-damaged populations. The naive malingerer is presumed not to know this and so “overplays” the role, performing worse than true amnesics. To test the presumption, four groups of subjects (normal college students, college students instructed to malinger amnesia, and memory-disordered patients with Huntington’s disease, and head trauma) were asked to freely recall a 20-item word list and then to attempt two-alternative, forced-choice recognition of each of the 20 words. As seen in FIGURE 1, the four groups differed significantly in recall performance. The normals differed from each of the other groups. The malingerers performed most poorly and were not significantly different from either of the patient groups.
An Advanced Vision System for the Automatic Inspection of Corrosions on Pole Tips in Hard Disk Drives

Pole tips of hard disk drives are made of FeCo film, which is prone to corrosion due to the corrosive nature of the environment and wide range of pH experienced during the production. A machine vision system is utilized for the automatic auditing of corroded pole tips. This comprises three steps: 1) extraction of the top shield region; 2) fusion of extracted features; and 3) decision making. This model is capable of detecting corrosion in the critical part of the pole tips. The experiments show that the proposed system detects corrosion with high accuracy, whereas the overall processing time meets industrial requirements.
Preadolescent internalizing and externalizing psychopathology : a developmental perspective

textabstractIn the field of child psychopathology research, a growing number of longitudinal studies have investigated early developmental precursors of maladaptive outcomes (see for reviews: Campbell, 1995; Koot, 1995; Sameroff and Seifer, 1990). The multitude of theoretical assumptions and related risk factors and outcomes represented by these studies calls for a more integrated approach to the study of the development of psychopathology. In such an approach, the developmental psychopathology paradigm and the distinction between internalizing and externalizing psychopathology are especially useful. The developmental psychopathology paradigm is a promising theoretical framework which provides a structured approach to the development of maladaptation across the life-span. This approach centers around the identification of endogenous and environmental factors that are involved in the early origins, course, and detection of psychopathology (Cicchetti and Cohen, 1995a; Koot, 2000). Because of the emphasis on the developmental aspect of psychopathology in this approach, the distinction between internalizing and externalizing expressions of dysfunction is of special interest, since it is the only consistently empirically identified classification across ages (Cicchetti and Toth, 1991). Internalizing disorders are characterized by disordered mood or behavior such as withdrawal, anxiety, or depression, while externalizing disorders are characterized by disordered behavior such as aggression, or delinquency, and hyperactivity (Achenbach and McConaughy, 1997; Cicchetti and Toth, 1991). In the following section, the developmental psychopathology perspective on the early origins, course, and detection of psychopathology will be introduced. This framework and salient gaps in related empirical efforts regarding intemalizing and externalizing psychopathology provide the basis for this thesis.
On Metapsychology, the Theory of Psychoanalysis: Beyond the Pleasure Principle, The Ego and the Id and Other Works

Covering the last three decades of Freud's life, this collection provides a chronological account of Freudian metapsychology, enabling the reader to trace the development of Freud's thought and modification of his theories in the light of his findings from his clinical work. These writings cover all the topics central to psychoanalytical theory: the role of the unconscious in mental life, instinct theory (including the life and death instincts and the concepts of repetition compulsion), reality-testing and the ego's relation to the external world.
Communication in Close Relationships

When critical, verbally disinhibited women are paired with verbally inhibited men, relationship quality suffers, rendering the relationship precarious. This effect theoretically emerges when (a) verbally disinhibited women pair with relatively inhibited men (man-more-inhibited couples) and (b) the disin-hibition of women in man-more-inhibited couples amplifies women's criticalness and alienates men. Three studies (Ns ϭ 437, 300, and 564) provided evidence that relationship quality suffered in man-more-inhibited couples; a 4th study (N ϭ 168) showed that the criticalness of women in man-more-inhibited couples did indeed undermine relationship quality. Implications for understanding the impact of gender expectations on relationships and for integrating behavioral and personological approaches to close relationships are discussed. What is the source of the ineffable " chemistry " that some couples enjoy? This question is both fascinating and frustrating: Fascinating because of its richness and complexity; frustrating because it has proven difficult to answer. Indeed, although researchers have made significant strides in understanding why members of some couples get along better than others, many key issues remain cloaked in mystery. Some of the most promising attempts to identify the roots of relationship harmony have focused on what goes wrong in troubled couples. Some researchers have reported that distressed marriages are often characterized by a wife-demand/husband-withdraw pattern (e. in which women make demands because they lack power in their relationships, and men withdraw because they feel that they have nothing to gain from confrontations (Christensen & Heavey, 1990). In this same tradition , Gottman and his colleagues (e. have identified an interaction pattern that is highly predic-tive of divorce. Dubbed stonewalling, it occurs when husbands emotionally withdraw from their partners during conflict and say nothing. The research on demand–withdrawal and stonewalling has suggested that some male–female qualities may combine synergisti-cally (Robins, Caspi, & Moffitt, 2000, 2002), with certain combinations being particularly toxic. But precisely what are these characteristics? In this report, we suggest that people's chronic communication styles may contribute to such synergistic reactions. More specifically, we argue that individual differences in the extent to which people inhibit their verbal responses can exert a powerful impact on how well they get along with their relationship partners. Virtually all humans possess a basic desire to connect with others and be understood by them (Baumeister & Leary, 1995; Swann, Rentfrow, & Guinn, 2002). Nevertheless, the extent to which they use language to forge these connections varies considerably. At one end of a continuum, …
The association between abdominal obesity and characteristics of migraine attacks in Iranian adults

Background: Migraine is a primary headache disorder that affects the neurovascular system. Recent studies have shown that migraine patients with general obesity have higher characteristics of migraine attacks compared with normal weight patients, but data on central obesity are scarce. This study was done to assess the relationship between central obesity and the characteristics of migraine attacks in migraine patients. Materials and Methods: This cross-sectional study was conducted on 129 migraine patients (28 men and 101 women), aged 15–67 years, in Isfahan, Iran. Anthropometric measurements such as waist circumference (WC), hip circumference (HC), waist–hip ratio (WHR) and waist–height ratio (WHtR), as well as characteristics of migraine attacks such as severity, frequency, duration, and headache diary result (HDR) was determined for each participant. Linear regression was used to examine the association between anthropometric measurements and characteristics of migraine attacks. P value less than 0.05 was considered significant. Results: WC, WHR, and WHtR were positively associated with the severity (P-value: WC: 0.002, WHR: 0.002, WHtR: 0.001) and frequency (P-value: WC: 0.006, WHR: 0.01, WHtR: 0.002) of migraine attacks. Moreover, we found a significant association between WC (P = 0.001), WHR (P = 0.004), and WHtR (P < 0.001) with HDR. No significant relationship was observed between central obesity indicators and duration of migraine attacks. Conclusions: Central obesity indicators were positively associated with the severity and frequency of migraine attacks as well as HDR, but not with duration of attacks. Based on our findings, it can be concluded that weight loss may decrease the characteristics of migraine attacks.
Potential spread of multidrug-resistant coagulase-negative staphylococci through healthcare waste.

INTRODUCTION Healthcare waste (HCW) might potentially harbor infective viable microorganisms in sanitary landfills. We investigated the antimicrobial susceptibility patterns and the occurrence of the mecA gene in coagulase-negative Staphylococcus strains (CoNS) recovered from the leachate of the HCW in an untreated sanitary landfill. METHODOLOGY Bacterial identification was performed by physiological and molecular approaches, and minimum inhibitory concentrations (MICs) of antimicrobial drugs were determined by the agar dilution method according to CLSI guidelines. All oxacillin-resistant bacteria were screened for the mecA gene. RESULTS Out of 73 CoNS, seven different species were identified by 16S rDNA sequencing: Staphylococcus felis (64.4%; n = 47), Staphylococcus sciuri (26.0%; n = 19), Staphylococcus epidermidis (2.7%; n = 2), Staphylococcus warneri (2.7%; n = 2), Staphylococcus lentus (1.4%; n = 1), Staphylococcus saprophyticus (1.4%; n = 1), and Staphylococcus haemolyticus (1.4%; n = 1). Penicillin was the least effective antimicrobial (60.3% of resistance; n = 44) followed by erythromycin (39.8%; n = 29), azithromycin (28.8%; n = 21), and oxacillin (16.5%; n = 12). The most effective drug was vancomycin, for which no resistance was observed, followed by gentamicin and levofloxacin, for which only intermediate resistance was observed (22%, n = 16 and 1.4%, n = 1, respectively). Among the oxacillin-resistant strains, the mecA gene was detected in two isolates. CONCLUSIONS Considering the high antimicrobial resistance observed, our results raise concerns about the survival of putative bacterial pathogens carrying important resistance markers in HCW and their environmental spread through untreated residues discharged in sanitary landfills.
