Functional requirements of situational awareness in computer network security

The underpinning of situational awareness in computer networks is to identify adversaries, estimate impact of attacks, evaluate risks, understand situations and make sound decisions on how to protect valued assets swiftly and accurately. SA also underscores situation assessment in order to make accurate forecast in dynamic and complex environments. In this paper, situational awareness in computer network security is investigated. Functional attributes of situational awareness in computer network security are discussed: dynamism and complexity, automation, realtime processing, multisource data fusion, heterogeneity, security visualisation, decision control, risk assessment, resolution, forecasting and prediction.

On the Feasibility of Side-Channel Attacks with Brain-Computer Interfaces

Brain computer interfaces (BCI) are becoming increasingly popular in the gaming and entertainment industries. Consumer-grade BCI devices are available for a few hundred dollars and are used in a variety of applications, such as video games, hands-free keyboards, or as an assistant in relaxation training. There are application stores similar to the ones used for smart phones, where application developers have access to an API to collect data from the BCI devices. The security risks involved in using consumer-grade BCI devices have never been studied and the impact of malicious software with access to the device is unexplored. We take a first step in studying the security implications of such devices and demonstrate that this upcoming technology could be turned against users to reveal their private and secret information. We use inexpensive electroencephalography (EEG) based BCI devices to test the feasibility of simple, yet effective, attacks. The captured EEG signal could reveal the user's private information about, e.g., bank cards, PIN numbers, area of living, the knowledge of the known persons. This is the first attempt to study the security implications of consumer-grade BCI devices. We show that the entropy of the private information is decreased on the average by approximately 15%-40% compared to random guessing attacks.
High Grade (Large Cell) Neuroendocrine Carcinoma of the Nasopharynx: Novel Case Report with Touch Preparation Cytology and Positive EBV Encoded Early RNA

Fewer than five case reports of primary large cell neuroendocrine carcinoma of the nasopharynx are known to the authors. No previous reports have included examples of cytomorphology or have proven association with Epstein-Barr virus. We herein illustrate MRI findings, histopathologic features, immunohistochemical characterization, cytologic details, and in situ hybridization studies from a unique case of primary large cell neuroendocrine carcinoma of the nasopharynx in a 38-year-old Caucasian male patient. Recognition of rare tumor types of the nasopharynx allows for refinements in disease management and prognostication.
Rate and Predictors of Mucosal Healing in Patients with Inflammatory Bowel Disease Treated with Anti-TNF-Alpha Antibodies

Objective Mucosal healing (MH) is an important treatment goal in patients with inflammatory bowel disease (IBD), but factors predicting MH under medical therapy are largely unknown. In this study, we aimed to characterize predictive factors for MH in anti-TNF-alpha antibody-treated IBD patients. Methods We retrospectively analyzed 248 IBD patients (61.3% CD, 38.7% UC) treated with anti-TNF-alpha antibodies (infliximab and/or adalimumab) for MH, defined as macroscopic absence of inflammatory lesions (Mayo endoscopy score 0 or SES-CD score 0) in colonoscopies which were analyzed before and after initiation of an anti-TNF-alpha antibody treatment. Results In patients treated with only one anti-TNF-alpha antibody (“TNF1 group”, n = 202), 56 patients (27.7%) achieved complete MH at follow-up colonoscopy (median overall follow-up time: 63 months). In a second cohort (n = 46), which comprised patients who were consecutively treated with two anti-TNF-alpha antibodies (“TNF2 group”), 13 patients (28.3%) achieved complete MH (median overall follow-up time: 64.5 months). Compared to patients without MH, CRP values at follow-up colonoscopy were significantly lower in patients with MH (TNF1 group: p = 8.35×10−5; TNF2 group: p = 0.002). Multivariate analyses confirmed CRP at follow-up colonoscopy as predictor for MH in the TNF1 group (p = 0.012). Overall need for surgery was lower in patients with MH (TNF1 group: p = 0.01; TNF2 group: p = 0.03). Conclusions We identified low serum CRP level at follow-up colonoscopy as predictor for MH, while MH was an excellent negative predictor for the need for surgery.
Expressed Breast Milk as a Predictor of Neonatal Yeast Colonization in an Intensive Care Setting.

BACKGROUND Yeast colonization is a predictor for invasive infection in neonates. Candida albicans and Candida parapsilosis are leading causes of invasive fungal infection (IFI) in this population. This study examines maternal breast milk as a predictor of colonization of infants with yeast. METHODS Inclusion criteria were admission longer than 72 hours to the neonatal intensive care unit and parental consent. Cultures of expressed breast milk, when available, and swabs from oral, rectal, and inguinal sites were obtained weekly for 12 weeks, or until discharge, transfer, or death. Cultures were analyzed using standard laboratory methods. Clinical information was extracted from medical records. RESULTS One hundred thirty infants were enrolled from February 2011 to November 2012. Cultures were obtained in 129 patients. The median (interquartile range [IQR]) gestational age was 34.4 weeks (33.1-37.1 weeks). The median (IQR) birth weight was 2157.5 g (1740-3060 g). No infants developed IFIs. Twenty-nine (22%) infants were colonized with yeast. Potential correlates for colonization in univariate analysis included exposure to antenatal steroids, postnatal antibiotics, and receipt of breast milk containing yeast. Potential correlates that remained after multivariable logistic regression included exposure to antenatal steroids and receipt of breast milk containing yeast. In cases in which yeast was recovered from an individual infant and from the breast milk received by that infant, there was only 30% concordance between yeast species. DISCUSSION Recovery of yeast from breast milk is associated with colonization with yeast in the neonate. Because Candida transmission via breast milk had a 30% concordance, breast milk is only one of several ways colonization occurs. Further study is needed on mechanisms of colonization.

The surface-potential-based compact MOS model PSP is reviewed with special emphasis to features of interest to analog and RF designers. Various aspects of the model are discussed, such as Gummel symmetry, capacitance reciprocity at V DS = 0 V, parasitic resistances, junction modeling, distortion modeling, and noise modeling. Examples from circuit design are used to illustrate the benefits of the PSP model.
Mild cognitive impairment: historical development and summary of research

This review article broadly traces the historical development, diagnostic criteria, clinical and neuropathological characteristics, and treatment strategies related to mild cognitive impairment (MCI), The concept of MCI is considered in the context of other terms that have been developed to characterize the elderly with varying degrees of cognitive impairment Criteria based on clinical global scale ratings, cognitive test performance, and performance on other domains of functioning are discussed. Approaches employing clinical, neuropsychological, neuroimaging, biological, and molecular genetic methodology used in the validation of MCI are considered, including results from cross-sectional, longitudinal, and postmortem investigations. Results of recent drug treatment studies of MCI and related methodological issues are also addressed.
Funny Current and Cardiac Rhythm: Insights from HCN Knockout and Transgenic Mouse Models

In the adult animal the sinoatrial node (SAN) rhythmically generates a depolarizing wave that propagates to the rest of the heart. However, the SAN is more than a simple clock; it is a clock that adjusts its pace according to the metabolic requirements of the organism. The Hyperpolarization-activated Cyclic Nucleotide-gated channels (HCN1–4) are the structural component of the funny (If) channels; in the SAN the If current is the main driving electrical force of the diastolic depolarization and the HCN4 is the most abundant isoform. The generation of HCN KO and transgenic mouse models has advanced the understanding of the role of these channels in cardiac excitability. The HCN4 KO models that were first developed allowed either global or cardiac-specific constitutive ablation of HCN4 channels, and resulted in embryonic lethality. A further progress was made with the development of three separate inducible HCN4 KO models; in one model KO was induced globally in the entire organism, in a second, ablation occurred only in HCN4-expressing cells, and finally in a third model KO was confined to cardiac cells. Unexpectedly, the three models yielded different results; similarities and differences among these models will be presented and discussed. The functional effects of HCN2 and HCN3 knockout models and transgenic HCN4 mouse models will also be discussed. In conclusion, HCN KO/transgenic models have allowed to evaluate the functional role of the If currents in intact animals as well as in single SAN cells isolated from the same animals. This opportunity is therefore unique since it allows (1) to verify the contribution of specific HCN isoforms to cardiac activity in intact animals, and (2) to compare these results to those obtained in single cell experiments. These combined studies were not possible prior to the development of KO models. Finally, these models represent critical tools to improve our understanding of the molecular basis of some inheritable arrhythmic human pathologies.
Evaluating Effective Writing Instruction for Adolescent Students in an Emotional and Behavior Support Setting

A multiprobe multiple baseline design was used to evaluate the effectiveness of strategy instruction in persuasive quick writing with 5 seventh- and eighth-grade students who attended a county alternative placement school for students with severe emotional and behavioral disabilities. Students were taught to plan and write a 10-minute persuasive response using the Self-Regulated Strategy Development instructional model. Instruction was conducted over five 30-minute sessions plus three 10-minute sessions. Positive effects were noted for all students on the primary measure, quality of written responses. The effect of the intervention was maintained over time. All students reported that the instruction benefited performance.
Motivation after Failure in School Music Performance Classes: The Facilitative Effects of Strategy Attributions.

Socio-cognitive perspectives on motivation have helped to advance our understanding of how and why students are motivated to learn. The third session of the Ann Arbor Symposium, held in 1 982, provided a platform for applying motivation theory and research to music teaching and learning. Unfortunately, little research within the past decade has systematically examined motivation within music contexts. The purpose of this study was to investigate the effects of failure attribution feedback (ability, effort, strategy) and classroom goal structure (competitive, individualistic-standards, individualistic-progress) on motivational response and decision making. One hundred and seven instrumental music students in grades 5-8 were randomly assigned to one of nine treatment conditions (goal structure x attribution) and presented with a scenario describing the failure experience of a fictitious band student named "Bill. " Subjects then completed a 35-item questionnaire that addressed "Bill's" future behaviors and affective responses. On average, subjects believed "Bill" would (a) respond to failure by improving his performance, increasing his effort expenditure, and selecting more effective practice strategies and (b) receive support from his band director and peers in the future. There were no significant goal structure main effects or goal structure x attribution interactions. The most constructive responses occurred, however, when failure was attributed to the use of inappropriate strategies or insufficient effort, rather than lack of ability. Implications for music teachers are discussed. Motivation is an umbrella term for any number of psychological constructs that may be used to interpret goal-directed behavior. Numerous paradigms or models of motivation have evolved over the years, including "Freudian biological theories of negative urges, behavioristic theories positing external conditioning on a blank slate, and humanistic notions of an innate propensity for goodness or self-actualization," (McCombs, 1991). Currently, the socio-cognitive paradigm dominates psychology and motivation research. From this perspective, motivation is defined as a decisionThe authors are listed alphabetically; both made equal contributions to this research.

A spectrally composite reconstruction approach for improved resolution of pulsed photothermal temperature profiling in water-based samples

We report on the first experimental evaluation of pulsed photothermal radiometry (PPTR) using a spectrally composite kernel matrix in signal analysis. Numerical studies have indicated that this approach could enable PPTR temperature profiling in watery tissues with better accuracy and stability as compared to the customary monochromatic approximation. By using an optimized experimental set-up and image reconstruction code (involving a projected ν-method and adaptive regularization), we demonstrate accurate localization of thin absorbing layers in agar tissue phantoms with pronounced spectral variation of a mid-infrared absorption coefficient. Moreover, the widths of reconstructed temperature peaks reach 14–17% of their depth, significantly less than in earlier reports on PPTR depth profiling in watery tissues. Experimental results are replicated by a detailed numerical simulation, which enables analysis of the broadening effect as a function of temperature profile amplitude and depth.
CELL CONTACTS IN THE MOUSE MAMMARY GLAND

The nature and distribution of cell contacts have been examined in thin sections and freeze-fracture replicas of mammary gland samples from female C3H/Crgl mice at stages from birth through pregnancy, lactation, and postweaning involution. Epithelial cells of major mammary ducts at all stages examined are linked at their luminal borders by junctional complexes consisting of tight junctions, variable intermediate junctions, occasional small gap junctions, and one or more series of desmosomes. Scattered desmosomes and gap junctions link ductal epithelial and myoepithelial cells in all combinations; hemidesmosomes attach myoepithelial cells to the basal lamina. Freeze-fracture replicas confirm the erratic distribution of gap junctions and reveal a loose, irregular network of ridges comprising the continuous tight-junctional belts. Alveoli develop early in gestation and initially resemble ducts. Later, as alveoli and small ducts become actively secretory, they lose all desmosomes and most intermediate junctions, whereas tight and gap junctions persist, The tight-junctional network becomes compact and orderly, its undulating ridges oriented predominantly parallel to the luminal surface. It is suggested that these changes in junctional morphology, occurring in secretory cells around parturition, may be related to the greatly enhanced rate of movement of milk precursors and products through the lactating epithelium, or to the profound and recurrent changes in shape of secretory cells that occur in relation to myoepithelial cell contraction, or to both.
Nonconscious Fear Conditioning, Visceral Perception, and the Development of Gut Feelings

When people are presented with backward-masked images of fear-relevant stimuli and only some of these images are paired consistently with electric shocks, they can predict the occurrence of shocks even though they do not consciously know which images they have seen. We postulated that they may use the perception of visceral cues from the conditional fear response to facilitate the prediction of shocks. In this study, ability to detect heartbeats was used to index sensitivity to visceral cues. The results showed that subjects who could detect their heartbeats performed better than chance in predicting whether or not they would receive a shock during the conditioning task. The findings support the notion that hunches, or “gut feelings,” are based in part on the perception of visceral cues.
Community College Transfer Students: A Case Study of Survival

Abstract: This qualitative study of community college transfer students at a private university sought students’ perceptions both of the transfer process and of institutions’ academic environments. Students perceived themselves as receiving little help from either institution in the transfer process. Similarly in the academic environment of the university, the successful student was one who was fairly self-reliant, able to survive with minimal instructional help.
Embodied conversational agents

Embodied conversational agents are computer-generated cartoonlike characters that demonstrate many of the same properties as humans in face-to-face conversation, including the ability to produce and respond to verbal and nonverbal communication. They constitute a type of (a) multimodal interface where the modalities are those natural to human conversation: speech, facial displays, hand gestures, and body stance; (b) software agent, insofar as they represent the computer in an interaction with a human or represent their human users in a computational environment (as avatars, for example); and (c) dialogue system where both verbal and nonverbal devices advance and regulate the dialogue between the user and the computer. With an embodied conversational agent, the visual dimension of interacting with an animated character on a screen plays an intrinsic role. Not just pretty pictures, the graphics display visual features of conversation in the same way that the face and hands do in face-to-face conversation among humans.This book describes research in all aspects of the design, implementation, and evaluation of embodied conversational agents as well as details of specific working systems. Many of the chapters are written by multidisciplinary teams of psychologists, linguists, computer scientists, artists, and researchers in interface design. The authors include Elisabeth Andre, Norm Badler, Gene Ball, Justine Cassell, Elizabeth Churchill, James Lester, Dominic Massaro, Cliff Nass, Sharon Oviatt, Isabella Poggi, Jeff Rickel, and Greg Sanders.
THE X-RAY ZURICH ENVIRONMENTAL STUDY (X-ZENS). I. CHANDRA AND XMM-NEWTON OBSERVATIONS OF ACTIVE GALACTIC NUCLEI IN GALAXIES IN NEARBY GROUPS

We describe X-ray observations with Chandra and XMM-Newton of 18 Mgroup ∼ 1–6 × 1013 M☉, z ∼ 0.05 galaxy groups from the Zurich ENvironmental Study. The X-ray data aim at establishing the frequency and properties, unaffected by host galaxy dilution and obscuration, of active galactic nuclei (AGNs) in central and satellite galaxies, also as a function of halo-centric distance. X-ray point-source detections are reported for 22 of the 177 galaxies, down to a sensitivity level of f0.5 − 8 keV ∼ 5 × 10−15 erg cm−2 s−1, corresponding to a limiting luminosity of L0.5 − 8 keV ∼ 3 × 1040 erg s−1. With the majority of the X-ray sources attributed to AGNs of low-to-moderate levels (L/LEdd ≳ 10−4), we discuss the detection rate in the context of the occupation of AGNs to halos of this mass scale and redshift and compare the structural and morphological properties between AGN-active and non-active galaxies. At galaxy mass scales <1011 M☉, central galaxies appear to be a factor of ∼4 more likely to host AGNs than satellite galaxies of similar mass. This effect, coupled with the tendency for AGNs to be hosted by massive galaxies, explains the (weak) trend for AGNs to be preferentially found in the inner parts of group halos, with no detectable trend with halo-centric distance in the frequency of AGNs within the satellite population. Finally, our data indicate that the rate of decline with redshift of AGN activity in galaxy groups matches that of the global AGN population, indicating that either AGN activity occurs preferentially in group halos or that the evolution rate is independent of halo mass.
Sampling and reconstruction effects due to motion in diffusion‐weighted interleaved echo planar imaging

Subject motion during diffusion‐weighted interleaved echo‐planar imaging causes k‐space offsets which lead to irregular sampling in the phase‐encode direction. For each image, the k‐space shifts are monitored using 2D navigator echoes, and are shown to lead to a frequent violation of the Nyquist condition when an ungated sequence is used on seven subjects. Combining data from four repeat acquisitions allows the Nyquist condition to be satisfied in all but 1% of images.
Eigenvectors in the superintegrable model II: ground-state sector

In 1993, Baxter gave eigenvalues of the transfer matrix of the N-state superintegrable chiral Potts model with the spin-translation quantum number Q, where mQ = ⌊(NL − L − Q)/N⌋. In our previous paper we studied the Q = 0 ground-state sector, when the size L of the transfer matrix is chosen to be a multiple of N. It was shown that the corresponding τ2 matrix has a degenerate eigenspace generated by the generators of r = m0 simple algebras. These results enable us to express the transfer matrix in the subspace in terms of these generators E±m and Hm for m = 1, …, r. Moreover, the corresponding 2r eigenvectors of the transfer matrix are expressed in terms of rotated eigenvectors of Hm.
Mathematical models and control algorithms for dynamic optimization of multicore platforms: A complex dynamics approach

The continuous increase in integration densities contributed to a shift from Dennard's scaling to a parallelization era of multi-/many-core chips. However, for multicores to rapidly percolate the application domain from consumer multimedia to high-end functionality (e.g., security, healthcare, big data), power/energy and thermal efficiency challenges must be addressed. Increased power densities can raise on-chip temperatures, which in turn decrease chip reliability and performance, and increase cooling costs. For a dependable multicore system, dynamic optimization (power / thermal management) has to rely on accurate yet low complexity workload models. Towards this end, we present a class of mathematical models that generalize prior approaches and capture their time dependence and long-range memory with minimum complexity. This modeling framework serves as the basis for defining new efficient control and prediction algorithms for hierarchical dynamic power management of future data-centers-on-a-chip.
