Experiential avoidance and well-being: A daily diary analysis

Experiential avoidance (EA) is a regulatory strategy characterised by efforts to control or avoid unpleasant thoughts, feelings and bodily sensations. Most studies of EA have used trait measures without considering the effects of EA on psychological functioning in naturalistic settings. To address this gap, we used daily diary methodology to examine the influence of EA of anxiety on everyday well-being. For two weeks, 89 participants provided daily reports of EA, positive and negative affect, enjoyment of daily events and meaning in life (MIL). Daily EA predicted higher negative affect, lower positive affect, less enjoyment of daily events (exercising, eating food and listening to music) and less MIL. The effect of EA on positive affect was not accounted for by the amount of negative affect experienced. Our daily measure of EA was a stronger predictor of daily well-being than a traditional trait measure (The Acceptance and Action Questionnaire). Taken together, results offer insights into the adverse effects of EA on daily well-being and suggest that EA is a context-specific regulatory strategy that might be best captured using a state-dependent measure.
Long Term Osmotic Mini Pump Treatment with Alpha-MSH Improves Myocardial Function in Zucker Diabetic Fatty Rats

The present investigation evaluates the cardiovascular effects of the anorexigenic mediator alpha-melanocyte stimulating hormone (MSH), in a rat model of type 2 diabetes. Osmotic mini pumps delivering MSH or vehicle, for 6 weeks, were surgically implanted in Zucker Diabetic Fatty (ZDF) rats. Serum parameters, blood pressure, and weight gain were monitored along with oral glucose tolerance (OGTT). Echocardiography was conducted and, following sacrifice, the effects of treatment on ischemia/reperfusion cardiac injury were assessed using the isolated working heart method. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity was measured to evaluate levels of oxidative stress, and force measurements were performed on isolated cardiomyocytes to determine calcium sensitivity, active tension and myofilament co-operation. Vascular status was also evaluated on isolated arterioles using a contractile force measurement setup. The echocardiographic parameters ejection fraction (EF), fractional shortening (FS), isovolumetric relaxation time (IVRT), mitral annular plane systolic excursion (MAPSE), and Tei-index were significantly better in the MSH-treated group compared to ZDF controls. Isolated working heart aortic and coronary flow was increased in treated rats, and higher Hill coefficient indicated better myofilament co-operation in the MSH-treated group. We conclude that MSH improves global heart functions in ZDF rats, but these effects are not related to the vascular status.
Multiple Frequency Band and High Isolation Mobile Device Antennas Using a Capacitive Slot

The performance characteristics of the capacitive slot, or a slot placed between the feed and ground connections, in a planar inverted-F antenna (PIFA) are comprehensively analyzed. The PIFA capacitive slot behavior is measured inside a two antenna system within a mobile phone where the first antenna is a multiple band PIFA and the second antenna is a higher frequency band PIFA directly overlapping with the first antenna higher frequency band. The dual band PIFA in this paper is designed to be resonant in the quad-band GSM+3G/4G, and the second PIFA is resonant in the 3G/4G frequency bands. The capacitive slot has three types of behaviors: affect the matching of existing frequency resonances, induce another frequency resonance, and improve the isolation between the two antennas. Together with optimal antenna ground and feed placement, the capacitive slot can act as a notched bandstop filter to decrease the S21 mutual coupling between the two antennas by over 20 dB and decrease the envelope correlation by almost one order of magnitude.
Simple Techniques for Enhancing the Robustness of DSR

The Dynamic Source Routing protocol for ad hoc networks is one of the leading candidates for adoption by the IETF amongst the class of reactive routing protocols. The currently defined protocol assumes total node cooperation, which allows attacks by failed or malicious nodes whose behaviour violates the protocol rules. Failed nodes will typically fail to forward information; badly failed nodes will inadvertently introduce false routing messages; selfish nodes deliberately refuse to forward packets; finally, malicious nodes may disrupt the network in any possible way. There have been many proposals for securing DSR, most of which introduce major overheads and hence make the protocol less attractive. This paper takes a somewhat different approach and presents some simple techniques aimed at making the protocol more robust with minimal overhead
Advances in Optical Coherence Tomography and Microscopy for endoscopic applications and functional neuroimaging

Optical Coherence Tomography (OCT) is a developing medical imaging technology that generates micron resolution cross-sectional images of subsurface internal tissue structure in situ and in real time, without the need to remove and process specimens. Previous studies have suggested that OCT holds great potential for use in laparoscopic and endoscopic applications to detect early stage neoplastic pathologies. A minimally invasive imaging modality capable of identifying pre-malignant tissues in vivo could be used to guide conventional excisional biopsy and histology, thereby reducing sampling error and enabling earlier detection and treatment. One limitation of prior endoscopic OCT imaging methods is the inability to visualize cellular features characteristic of early disease states such as neoplasia. This thesis seeks to demonstrate that advances in OCT resolution and in miniaturized imaging devices will lead to enhanced visualization of pathologic changes in vivo at both the tissue architectural and cellular levels. Toward this goal, three technological advances are made. First, compact and portable laser light sources for clinical ultrahigh resolution OCT are demonstrated based on supercontinuum generation in highly nonlinear optical fibers. Second, an extension of OCT called optical coherence microscopy (OCM) is developed for in vivo cellular imaging. High speed OCM system designs are demonstrated and characterization of OCM imaging parameters is performed. Importantly, this work demonstrates that OCM can make use of broadband laser sources to image cellular features with reduced numerical aperture compared to confocal microscopy, thereby facilitating the development of small diameter endoscopic probes. Third, two-axis scanning catheters based on micromirror technology are designed and demonstrated for ultrahigh resolution threedimensional and en face OCT imaging. To demonstrate feasibility of these advances in future clinical applications, ex vivo imaging studies of endoscopically accessible human gastrointestinal tissues including key pathologies are performed. Results demonstrate that three-dimensional and cellular resolution optical coherence imaging can significantly improve performance over conventional OCT methods for gastrointestinal endoscopy. Finally, this thesis also explores a new application for optical coherence tomography in neuroscience. Optical methods are currently being used to study the neurovascular response to functional activation, but most existing techniques lack depth resolution. Through correlation with video microscopy, OCT is shown to enable depth-resolved cross-sectional imaging of functional activation in the important rat somatosensory cortex model system. With further development, OCT may offer a new tool for basic and applied neuroscience research. Thesis Supervisor: James G. Fujimoto Professor of Electrical Engineering and Computer Science
A Review on Risk Score Based App Classification Using Enriched Contextual Information of App Context

As the use of mobile devices is increasing rapidly day by day, huge number of mobile apps are coming into the market. Many of these apps are providing similar functionality and are coming from multiple unknown vendors. As a result, having a proper classification of these apps can turn out to be useful for various purposes like making it easy and time efficient for the user to select the required app, understanding the user preferences that can motivate the intelligent personalized services, etc. Having a effective classification for proper mobile app usage analysis, effective classification is required for which there is a need to have detailed information about the app. However this is nontrivial task as limited contextual information is available. As the information available about the apps is short and spares, classification of the apps can also be considered as coming into the category of classification of short and spares text. Various methods to classify the short and sparse text are present, which can be used for classification of the mobile apps. In this paper we have presented one such method in which we will be extracting the contextual information from sources like information from the labels (app name), information from the web search engine (snippets) and the contextual usage history of the app collected from the users usage record and also we will extract the permissions of the app requests before being installed. This is will give us effective and secure classification of the apps as most of these apps are coming from an unknown vendors and so they have the higher possibility of being malicious. Keywords— Mobile app classification, Risk, Malware, Web knowledge, enriched contextual information, data mining.
Involvement of inflammation in normal pregnancy

To study the role of inflammation throughout normal pregnancy and postpartum, 37 women with normal pregnancies, including normal neonatal outcome, participated. Blood and urine samples were collected from each woman at least six times during pregnancy and postpartum. Plasma levels of interleukin‐6 (IL‐6) and tumor necrosis factor‐α (TNF‐α) and urinary levels of a prostaglandin‐F2α (PGF2α) metabolite were measured. Median, 25th to 75th centile and average change per gestational week of IL‐6, TNF‐α and the PGF2α metabolite were measured. Levels of IL‐6 increased significantly throughout pregnancy and remained high postpartum. No change in TNF‐α could be seen. The PGF2α metabolite levels increased significantly throughout pregnancy and decreased postpartum. These results suggest that mild but significant inflammatory activity is involved in the development of normal pregnancy, which might have important physiological roles.
Music listening history explorer: an alternative approach for browsing music listening history habits

Nowadays, people spend time using services to track their music listening history. Although these services provide statistics and small graphics/charts, they are mainly used to record and to allow direct access to the information, not providing any visualization and exploration functionality. In this paper we describe a new approach for browsing and visualizing music listening histories, which combines a timeline-based visualization, with a set of synchronized-views and an interactive filtering mechanism to provide a flexible and easy to use solution. This was complemented with brushing and highlighting techniques that allow users to observe trends on artists, albums and tracks listening. Experimental evaluation with users revealed that they were able to complete all the proposed tasks with a low error rate, and that they found the solution easy to use. Moreover, users liked our approach for browsing and exploring listening histories, emphasizing its flexibility and effectiveness, and founding the full experience engaging and rewarding.
Magnetic resonance imaging of the brain: Blood partition coefficient for water: Application to spin‐tagging measurement of perfusion

We describe the use of relative proton density imaging to obtain spatially resolved measurements of the brain:blood partition coefficient for water. Values of relative proton density and apparent‐T1 were calculated by performing a multidimensional nonlinear least squares fit of progressive saturation image data. Correction for magnetic field inhomogeneity was included. The partition coefficient was calculated by dividing the relative proton density of brain by the relative proton density of blood water. Results obtained from healthy volunteers demonstrate significant spatial variation in the partition coefficient in brain. Direct measurement of this parameter eliminates a source of error in the calculation of regional perfusion using arterial spin‐tagging techniques.
ExtrAns, an answer extraction system

Les systemes d'Extraction de Reponses (ER) recuperent dans des documents des expressions qui repondent directement a des questions du langage courant. L'ER pour des manuels techniques exige un haut niveau de rappel et de precision ; pourtant, ce sont de petites unites de texte qui doivent etre recuperees. C'est pourquoi il est important d'effectuer une analyse linguistique detaillee. Nous presentons ici ExtrAns, un systeme d'ER pour des manuels Unix qui utilise une analyse syntaxique complete, une desambiguisation partielle et un module de resolution d'anaphores pour generer les formes logiques minimales correspondant aux documents et a la requete. La procedure de recherche se sert d'un algorithme de demonstration de la requete sur la representation en clauses de Horn des formes logiques minimales. Les ambiguites non resolues sont traitees a l'aide d'une mise en evidence graduelle.
The experiences and perceptions of police members regarding the effectiveness of trauma debriefing within the South African Police Service

THE EXPERIENCES AND PERCEPTIONS OF POLICE MEMBERS REGARDING THE EFFECTIVENESS OF TRAUMA DEBRIEFING WITHIN THE SOUTH AFRICAN POLICE SERVICE Candidate: Tinyiko Godfrey Chabalala Department: Social work B University of Pretoria Supervisor: Prof. L.S. Terblanche Degree: MSOC SCI (EAP) Certain individuals, such as police officers, are exposed to traumatic events as part of the occupational roles they fulfill. In order to prevent psychological illnesses; namely the Post-Traumatic Stress Disorder (PTSD) that results from work-related traumatic incidents, psychological interventions have been developed such as Critical Incident Stress Debriefing. The aim of the study was to explore the experiences and the perceptions of police members stationed at the South African Police Service (SAPS) Head Office in Pretoria, regarding the effectiveness of Trauma Debriefing within the SAPS environment. The researcher was motivated to choose this subject as a result of the challenges he faced while working as a Psychometrist and a Debriefer within the SAPS. Furthermore, the lack of research and literature studies concerning the effectiveness of trauma debriefing motivated the researcher to conduct the study.

Specificity of immunoglobulin heavy chain switch correlates with activity of germline heavy chain genes prior to switching.

IgM+ cells cultured from the I.29 B cell lymphoma can be induced with lipopolysaccharide (LPS) or, to a greater extent, with LPS plus anti‐idiotype antibody to switch to IgG2a, IgE or IgA expression. The isotype switch is accompanied by rearrangement of immunoglobulin (Ig) heavy (H) chain genes. Here we demonstrate that the commitment of the I.29 IgM+ cells to switch to IgA appears to be manifested by hypomethylation of the alpha constant region genes in IgM+ cells, and by the presence of small amounts of RNAs transcribed from non‐rearranged alpha gene(s) in IgM+ cells. The commitment to switch to IgE or IgG2a is also in accord with the presence of small amounts of RNA transcripts from the non‐rearranged epsilon and gamma 2a genes, although the hypomethylation of the epsilon and gamma 2a genes is not as dramatic as that of the alpha genes. These results suggest that I.29 cells switch specifically to IgA, IgE or IgG2a due to the activation of the corresponding H chain constant region genes in IgM+ cells prior to the actual switch recombination event.
Activation of Src induces mitochondrial localisation of de2-7EGFR (EGFRvIII) in glioma cells: implications for glucose metabolism

A common mutation of the epidermal growth factor receptor in glioma is the de2-7EGFR (or EGFRvIII). Glioma cells expressing de2-7EGFR contain an intracellular pool of receptor with high levels of mannose glycosylation, which is consistent with delayed processing. We now show that this delay occurs in the Golgi complex. Low levels of de2-7EGFR were also seen within the mitochondria. Src activation dramatically increased the amount of mitochondrial de2-7EGFR, whereas its pharmacological inhibition caused a significant reduction. Because de2-7EGFR is phosphorylated by Src at Y845, we generated glioma cells expressing a Y845F-modified de2-7EGFR. The de2-7EGFR(845F) mutant failed to show mitochondrial localisation, even when co-expressed with constitutive active Src. Low levels of glucose enhanced mitochondrial localisation of de2-7EGFR, and glioma cells expressing the receptor showed increased survival and proliferation under these conditions. Consistent with this, de2-7EGFR reduced glucose dependency by stimulating mitochondrial oxidative metabolism. Thus, the mitochondrial localisation of de2-7EGFR contributes to its tumorigenicity and might help to explain its resistance to some EGFR-targeted therapeutics.

Enabling technologies for future all-optical packet switched networks

This paper addresses the challenges hindering all-optical packet switched networks and it focuses on the technologies that will make it possible. The basic structure of an optical packet switching router is presented. On the basis of the design, the need for optical buffers is justified and the adequacy of optical labels to perform routing is defended. Subsequently, the principles and techniques for developing slow-light based optical buffers are addressed and the photonic crystal approach to slow-light buffering is discussed, highlighting its benefits and challenges. The peculiar design flexibility of this approach is demonstrated with simulations. Ultimately, optical labelling is briefly presented as a beneficial approach for the switching layer.
Fractional CO2 laser‐assisted drug delivery

Ablative fractional resurfacing (AFR) creates vertical channels that might assist the delivery of topically applied drugs into skin. The purpose of this study was to evaluate drug delivery by CO2 laser AFR using methyl 5‐aminolevulinate (MAL), a porphyrin precursor, as a test drug.
From Weighted to Unweighted Model Counting

The recent surge of interest in reasoning about probabilistic graphical models has led to the development of various techniques for probabilistic reasoning. Of these, techniques based on weighted model counting are particularly interesting since they can potentially leverage recent advances in unweighted model counting and in propositional satisfiability solving. In this paper, we present a new approach to weighted model counting via reduction to unweighted model counting. Our reduction, which is polynomial-time and preserves the normal form (CNF/DNF) of the input formula, allows us to exploit advances in unweighted model counting to solve weighted model counting instances. Experiments with weighted model counters built using our reduction indicate that these counters performs much better than a state-of-the-art weighted model counter.
Local Rules for Computable Planar Tilings

Aperiodic tilings are non-periodic tilings characterized by local constraints. They play a key role in the proof of the undecidability of the domino problem (1964) and naturally model quasicrystals (discovered in 1982). A central question is to characterize, among a class of non-periodic tilings, the aperiodic ones. In this paper, we answer this question for the well-studied class of non-periodic tilings obtained by digitizing irrational vector spaces. Namely, we prove that such tilings are aperiodic if and only if the digitized vector spaces are computable.
Exclusive Use Spectrum Access Trading Models in Cognitive Radio Networks: A Survey

Spectrum frequency is a valuable resource for wireless communication but very limited in its availability. Due to the extensive use and ever increasing demand of spectrum bands by wireless devices and newer applications, unlicensed band is becoming congested, while licensed bands are found mostly underutilized. To solve this problem of spectrum scarcity, cognitive radio (CR) devices can share licensed bands opportunistically in several ways. We analyze the three main dynamic sharing models (commons, shared-use, and exclusive-use) proposed in literature with extensive analysis of the exclusive-use model, which is the most promising as it provides benefits to both licensed and unlicensed users. In this model, CR-enabled service providers, also known as secondary service providers, can buy or lease spectrum from licensed, known as primary service providers, for both short and long duration and gain exclusive rights to access the spectrum. In this survey paper, exclusive-use trading approaches, namely, game theory, market equilibrium, and classical, hybrid and other models are reviewed extensively and their characteristics and differences are highlighted and compared. We also propose possible future research directions on exclusive-use CR model.
