description: We compare simulations of the Lyman-alpha forest performed with two different hydrodynamical codes, Gadget-2 and Enzo. A comparison of the dark matter power spectrum for simulations run with identical initial conditions show differences of 1-3% at the scales relevant for quantitative studies of the Lyman-alpha forest. This allows a meaningful comparison of the effect of the different implementations of the hydrodynamic part of the two codes. Using the same cooling and heating algorithm in both codes the differences in the temperature and the density probability distribution function are of the order of 10%. These differences can be mainly attributed to a slight mismatch in the resolution. The differences are smaller than or equal to the effects of boxsize and resolution on these statistics. Once resolution effects are taken into account the differences in the flux power spectrum - the statistics most widely used for estimating the matter power spectrum and cosmological parameters from Lyman-alpha forest data - are about 5%. This is again smaller than or equal to the effects of boxsize and resolution. Numerical uncertainties due to a particular implementation of solving the hydrodynamic or gravitational equations appear therefore to contribute only moderately to the error budget in estimates of the flux power spectrum from numerical simulations. We further find that the differences in the flux power spectrum for Enzo simulations run with and without adaptive mesh refinement are also of order 5% or smaller. The latter require 10 times less CPU time making the CPU time requirement similar to that of a version of Gadget-2 that is optimised for Lyman-alpha forest simulations.

description: In this research thesis, I explain David Chaum's patent that describes the Man-In-The-Middle (MITM) detection protocol. The MITM Detection Protocol (MDP) uses three stages to entrap an adversary that reveals her existence based on contextual information from each scenario. One of the primary goals of this research is to develop a detailed understanding of Chaum's novel concept since the language describing the MDP presented a clouded explanation. My second goal is to re-describe the protocol using conventional notation and illustrations for two cases in each scenario, with and without an adversary. The explicit illustrations provided within this paper clearly define the exchange between two communicants and their ability to detect an adversary. I define the assumptions based around the common random string model that eliminates prior exchange of information and distribution of shared secrets. A discussion follows the explanation of the protocol which concludes that Chaum's MDP adds technical value and merit towards achieving a MITM detection mechanism based on a restrictive assumption set; however, the elevated complexity experienced by the user contributed to the lack of integration and acceptance of the MDP onto existing hardware solutions.

description: Youth ages 15 to 24 account for half of the estimated 20 million new cases of Sexually Transmitted Infections (STIs) that occur each year (CDC, 2013).  Consistent condom use is an important intervention target to prevent STI contraction among youth.  The present study evaluated whether motivation and self-efficacy to use condoms predict subsequent consistency of condom use in a community sample (N=166) of female youth (ages 13-21) at increased risk for STI contraction.  Additionally, the current study investigated if these relations are moderated by frequency of sex under the influence.  Exploratory analyses investigated these relations in sex events with steady boyfriends only separately from sex events with other guys only. Data were analyzed from Project SAFE, a randomized controlled clinical trial investigating the efficacy of a Computer-Assisted Motivational Intervention compared to Didactic Educational Counseling for sexual risk and protective behaviors.   Both motivation and self-efficacy to use condoms demonstrated a significant positive linear relation with subsequent consistency of condom use.  However, there was limited evidence for the moderating effect of frequency of sex under the influence.  There was some indication that the pattern of results differed in exploratory analyses including only sex events with steady boyfriends compared to sex events with other guys.  Analyses were re-estimated including past consistency of condom use as a covariate.  In these analyses there was some evidence for a negative main effect of frequency of sex under the influence.  These finding have implications for the development of tailored interventions and future research.

description: Supervised classification techniques use training samples to find classification rules with small expected 0-1 loss. Conventional methods achieve efficient learning and out-of-sample generalization by minimizing surrogate losses over specific families of rules. This paper presents minimax risk classifiers (MRCs) that do not rely on a choice of surrogate loss and family of rules. MRCs achieve efficient learning and out-of-sample generalization by minimizing worst-case expected 0-1 loss w.r.t. uncertainty sets that are defined by linear constraints and include the true underlying distribution. In addition, MRCs' learning stage provides performance guarantees as lower and upper tight bounds for expected 0-1 loss. We also present MRCs' finite-sample generalization bounds in terms of training size and smallest minimax risk, and show their competitive classification performance w.r.t. state-of-the-art techniques using benchmark datasets.

description: We study the optical emission from single semiconductor quantum dots coupled to the optical modes of photonic crystal nanocavities. For dots that are both spectrally and spatially coupled, auto-correlation measurements reveal efficient single photon generation, with a drastically reduced lifetime due to the Purcell-effect. However, the multi-photon emission probability is enhanced compared to the same QD transition when it is detuned from the cavity mode by controlled $N_2$-deposition. This indicates the presence of an emission background that is shown to be related to the dot using photon cross-correlation spectroscopy. Photon temporal correlations persist even for large spectral detunings beyond $Δλ\sim-10 nm$, excluding the intrinsic QD continuum and phonon mediated processes as being responsible for the cavity mode emission background. We propose a mechanism based on photon induced shake up processes in the charged quantum dots, enhanced by the optical cavity.

description: Objectives: The Speech Handicap Index (SHI) is a self-reported speech-related quality of life assessment originally developed for measuring the psychosocial speech impact in patients with oral or pharyngeal cancer. This review article provides a scoping review of the literature on the validated SHI, with the purpose of identifying and documenting available studies and procedures for the cultural adaption and validation of SHI.Method: Prime databases including PubMed, EMBASE, and Google Scholar were searched for journal publications reporting validation of the SHI. Reviews and reference cross-checking were performed using a priori selection criteria. A body of literature related to SHI was scoped and publication quality was categorized independently by two investigators. After applying all the screening criteria, articles that met the eligibility criteria were included in the review.Results: The scoping review yielded 10 articles that met the inclusion criteria presenting the SHI in eight different languages, including Dutch, U.K. English, French, Korean, Simplified Chinese (Mandarin), Lithuanian, Italian, and European Portuguese. All of them reported validity, reliability, and translation method.Discussion and Conclusions: High reliability and validity between various language versions of the SHI were identified. The current scoping review provides a useful summary and could be a helpful precursor to a systematic review on SHI in the future.

Exploring Structural and Functional Variation Among Opsin Classes

description: Opsins comprise a family of proteins belonging to the superfamily of G-protein coupled receptors (GPCRs).  The opsins combined with vitamin-A derived chromophores make up the photopigments responsible for such diverse functions as image- and nonimage-forming vision, entrainment of circadian cycles, and the pupillary light response.  The elucidation of the structural and biochemical properties of photopigments is of extreme importance to understanding the biological processes that they control.  Currently the crystal structure of two photopigments have been solved; bovine rhodopsin from the vertebrate visual opsins, and squid rhodopsin from the invertebrate visual opsins.  In the vertebrate visual opsins, five main subclasses exist; the RH1 class containing bovine rhodopsin makes up the rod based opsins, and the SWS1, SWS2, RH2, and M/LWS classes make up the cone based opsins.    I question how similar structurally and biochemically the cone opsin classes are to the RH1 class.  Using in vitro G-protein activation assays it is shown that mutations targeting key structural bonds within the cone opsin classes, compared to the RH1 class, result in different profiles of biochemical behavior reflective of structural variation surrounding the chromophore-binding pocket.  This structural variation is further explored through the use of spin-labeling techniques aimed at analyzing the helical arrangement within the M/LWS cone opsin class compared to the RH1 class.  In addition, a sixth class of opsins, the melanopsins, which maintains greater sequence identity to the invertebrate visual opsins than to the vertebrate visual opsins, is analyzed to identify the location of the counterion to the protonated Schiff base.  The counterion is a key functional residue within the opsin family responsible for stabilizing the inactive dark state pigment as well as tuning the wavelength absorbance into the visible spectrum.  Through spectroscopic analysis of various melanopsin mutants, evidence is presented that shows the counterion residue is not conserved across opsin groups. Through the evolution of the opsins, the location of the counterion has changed at least twice.  This work highlights the large level of complexity that exists in the structure of the opsin family emphasizing the need for further structural analysis.
THE RELATION BETWEEN SELF-EFFICACY AND BEHAVIORAL PROCESSES OF CHANGE AND THEIR IMPACT ON DRINKING OUTCOMES AFTER ALCOHOL TREATMENT

description: The predictive power of alcohol abstinence self-efficacy on drinking outcomes has been widely studied, yet important questions remain about the nature and conditions of its impact. The present study evaluated whether the effect of alcohol abstinence self-efficacy measured at the end of an alcohol treatment program was moderated by reported utilization of behavioral processes of change. It was hypothesized that self-efficacy would be differentially important in predicting quantity and frequency of drinking post-treatment depending upon level of behavioral processes used, such that the relation between self-efficacy and outcomes would be stronger for individuals who reported low levels of processes. Data were analyzed from Project MATCH, a large, multisite alcohol treatment study. A significant curvilinear relation between end-of-treatment self-efficacy and 6- and 12-month post-treatment drinking outcomes was found, and as hypothesized, this relation was moderated by level of behavioral processes of change. Self-efficacy had a stronger impact on quantity and frequency of post-treatment drinking when low levels of behavioral processes were reported than when high levels were used. Individual behavioral processes were also examined, and the moderated relation was strongest for processes related to managing cues, reinforcements, and conditioned responses. These findings have importance treatment implications and highlight the complex nature of self-efficacy's impact on drinking outcomes.

description: Neptune remains a mysterious world that deserves further exploration and is a high-priority objective for a future planetary mission in order to better understand the formation and evolution of ice giant planets. We have developed a coupled ion-neutral 1D photochemical model of Neptune's atmosphere to study the origin and evolution of the hydrocarbons and the oxygen species. The up-to-date chemical scheme is derived from one used for Titan's atmosphere, which led to good agreements with the Cassini-CIRS observations for oxygen species and the main hydrocarbons. The main results we obtain are the following: The ion-neutral chemistry coupling produces aromatics (and benzene in particular) in the atmosphere of Neptune with relatively high abundances. Our model results are in good agreement with observations (taking model uncertainties into account). Two ionospheric peaks are present in the atmosphere located above the pressure level of 10$^{-5}$ mbar and around 10$^{-3}$ mbar. The influx of oxygen species in the upper atmosphere of Neptune has an effect on the concentration of many ions. We show that in situ exploration of Neptune's atmosphere would provide very interesting constraints for photochemical models concerning in particular the origin of oxygen species and the contribution of ion chemistry. A precise description of upper atmospheric chemistry is crucial for a better understanding of the internal composition and the formation processes of this planet.

description: Frugal innovations, i.e. affordable products and services with appropriately good quality, are getting increasingly important for securing long-term competitiveness in both, the developing world and in industry nations. Nevertheless, ensuring actual implementation of technology-driven frugal inventions remains an under-researched area. This study investigates modes and routines employed by techno-entrepreneurs from industry nations when innovating frugally. The study is based on the patent data of seven auto component sector firms from Germany with a documented history of contributing cost-effective solutions to frugal vehicles. With the help of a keyword analysis we identify the role of frugality in (patented) technical inventions. Select case studies of frugal inventions show that cost effectiveness and environmental sustainability can be often achieved by simplification of design and production process, as well as by eliminating avoidable complexity, e.g. through standardization. The study shows that frugal inventions in the investigated firms are often driven by individual inventors, while potentials of open global innovation networks are under-utilized. Furthermore, the study shows that frugality can (only) be achieved by a holistic approach that encompasses the entire value chain, including logistics and waste management. The results are potentially beneficial for techno-entrepreneurs across industry sectors and product domains.

The Relation Between Parent Distraction Behaviors and Child Distress During Pediatric Cancer Procedures
Creators: name: Thompson, Caitlin C
Publisher: name: Maryland Shared Open Access Repository
Year: 2012

description: This study examined the relation between child distress, parent distraction behaviors, and parent other nonprocedural talk during pediatric cancer procedures. Participants were 72 children with cancer (age 5 to 13 years old) and their mothers. Cancer procedures were videotaped and coded for parent behaviors and child distress. Contrary to hypotheses, child distress was positively related to parent verbal distraction and nonprocedural talk to the child and negatively related to nonprocedural talk to another adult in the room. Sequential analyses suggested that verbal distraction and nonprocedural talk to the child were more likely to occur after crying, while nonprocedural talk to another adult was less likely to occur after crying. Crying was less likely to occur after nonprocedural talk to another adult. Results suggest that nonprocedural talk to another adult functions differently than nonprocedural talk to the child; however, given the low frequency of behaviors, results should be interpreted with caution.

description: Preliminary results from a sensitive survey of the CO J=1--0, 2--1, 3--2, 4--3, 6--5, HCN J=1--0, 3--2, 4--3, and CI J=1--0 lines of a sample of 30 Ultraluminous Infrared Galaxies (ULIRGs) are presented. These reveal a tandalizing picture of the physical conditions of the molecular gas in these extraordinary galaxies ($\rm L_{FIR}>10^{12} L_{\odot}$), with a diffuse phase dominating the low-J CO lines and a much denser and warmer phase dominating the CO 4-3 and 6-5 and all the HCN lines. The CI J=1--0 emission was found to be a robust tracer of their total molecular gas mass under a large range of physical conditions, a potent alternative to the much weaker emission from the $ ^{13}$CO isotopologue, and especially promising as an H$_2$ tracer for similar objects at high redshifts.

description: A characteristic of reinforcement learning is the ability to develop unforeseen strategies when solving problems. While such strategies sometimes yield superior performance, they may also result in undesired or even dangerous behavior. In industrial scenarios, a system's behavior also needs to be predictable and lie within defined ranges. To enable the agents to learn (how) to align with a given specification, this paper proposes to explicitly transfer functional and non-functional requirements into shaped rewards. Experiments are carried out on the smart factory, a multi-agent environment modeling an industrial lot-size-one production facility, with up to eight agents and different multi-agent reinforcement learning algorithms. Results indicate that compliance with functional and non-functional constraints can be achieved by the proposed approach.

description: We consider a hole-doped semiconductor with a sharp boundary and study the boundary spin accumulation in response to a charge current. First, we solve exactly a single-particle quantum mechanics problem described by the isotropic Luttinger model in half-space and construct an orthonormal basis for the corresponding Hamiltonian. It is shown that the complete basis includes two types of eigenstates. The first class of states contains conventional incident and reflected waves, while the other class includes localized surface states. Second, we consider a many-body system in the presence of a charge current flowing parallel to the boundary. It is shown that the localized states contribute to spin accumulation near the surface. We also show that the spin density exhibits current-induced Friedel oscillations with three different periods determined by the Fermi momenta of the light and heavy holes. We find an exact asymptotic expression for the Friedel oscillations far from the boundary. We also calculate numerically the spin density profile and compute the total spin accumulation, which is defined as the integral of the spin density in the direction perpendicular to the boundary. The total spin accumulation is shown to fit very well the simple formula S ~(1 - m_L/m_H)^2, where m_L and m_H are the light- and heavy-hole masses. The effects of disorder are discussed. We estimate the spin relaxation time in the Luttinger model and argue that spin physics cannot be described within the diffusion approximation.

description: Landau damping mechanism plays a crucial role in providing single-bunch stability in LHC, High-Luminosity LHC, other existing as well as previous and future (like FCC) circular hadron accelerators. In this paper, the thresholds for the loss of Landau damping (LLD) in the longitudinal plane are derived analytically using the Lebedev matrix equation (1968) and the concept of the emerged van Kampen modes (1983). We have found that for the commonly-used particle distribution functions from a binomial family, the LLD threshold vanishes in the presence of the constant inductive impedance Im$Z/k$ above transition energy. Thus, the effect of the cutoff frequency or the resonant frequency of a broad-band impedance on beam dynamics is studied in detail. The findings are confirmed by direct numerical solutions of the Lebedev equation as well as using the Oide-Yokoya method (1990). Moreover, the characteristics, which are important for beam operation, as the amplitude of residual oscillations and the damping time after a kick (or injection errors) are considered both above and below the threshold. Dependence of the threshold on particle distribution in the longitudinal phase space is also analyzed, including some special cases with a non-zero threshold for Im$Z/k = const$. All main results are confirmed by macro-particle simulations and consistent with available beam measurements in the LHC.

description: In the quest for topological insulators with large band gaps, heterostructures with Rashba spin-orbit interactions come into play. Transition metal oxides with heavy ions are especially interesting in this respect. We discuss the design principles for stacking oxide Rashba layers. Assuming a single layer with a two-dimensional electron gas (2DEG) on both interfaces as a building block, a two-dimensional topological insulating phase is present when negative coupling between the 2DEGs exists. When stacking multiple building blocks, a two-dimensional or three-dimensional topological insulator is artificially created, depending on the intra- and interlayer coupling strengths and the number of building blocks. We show that the three-dimensional topological insulator is protected by reflection symmetry, and can therefore be classified as a topological crystalline insulator. In order to isolate the topological states from bulk states, the intralayer coupling term needs to be quadratic in momentum. It is described how such a quadratic coupling could potentially be realized by taking buckling within the layers into account. The buckling, thereby, brings the idea of stacked Rashba system very close to the alternative approach of realizing the buckled honeycomb lattice in [111]-oriented perovskite oxides.

description: The retina is susceptible to degenerative changes over the natural life-span, owing to a range of different factors, including genetic susceptibility and environmental and lifestyle factors such as smoking, diet and exposure to bright light. Photoreceptors, with their high metabolic demands and polyunsaturated fatty acid (PUFA)-rich outer segments (OS), are the most vulnerable of retinal cells, being sensitive to oxidative damage and inflammatory attack, resulting in cell death. Because the health and stability of the photoreceptors is essential to the maintenance of functional vision, rescue strategies aimed at stabilising photoreceptors are of critical importance. Exposure to electromagnetic wavelengths in the far-red (FR) to near-infrared (NIR) range (600nm-1000nm) has been reported to have beneficial effects for mammalian tissues in a variety of contexts. These include treatment of soft tissue injuries, radiation-induced ulcers, inflammatory conditions and neurodegenerative diseases. In the recent years, there has been an increasing interest in the use of 670nm red light to manage retinal injuries. The work presented in this thesis examines the effects of exposure to 670nm light in two established models of retinal degeneration in vivo; a light damage (LD) model using Sprague Dawley rats, and an oxygen-induced model of retinal degeneration (hyperoxia) using the C57Bl/6J mouse. The findings indicate that irradiation with 670nm light ameliorates retinal damage in both models, and its effects include modulation of gene expression. In the LD model, irradiation with 670nm light mitigates the damaging effects of white light in a dose-dependent manner, reducing measures of oxidative damage and inflammatory response. In the hyperoxia model, irradiation with 670nm light reduces photoreceptor cell death, mitigates oxidative stress, preserves the integrity of outer retinal barrier and slows down, but does not inhibit, retinal degeneration. The results provide evidence supporting the therapeutic potential of 670nm light in the treatment of retinal degenerative conditions where oxidative stress, cell death and inflammation are involved, particularly in the early stages of degeneration.

description: Bloggers make a huge impact on society by representing and influencing the people. Blogging by nature is about expressing and listening to opinion. Good sentiment detection tools, for blogs and other social media, tailored to politics can be a useful tool for today's society. With the elections around the corner, political blogs are vital to exerting and keeping political influence over society. Currently, no sentiment analysis framework that is tailored to Political Blogs exist. Hence, a modular framework built with replicable modules for the analysis of sentiment in blogs tailored to political blogs is thus justified. I propose Blogvox2, an information retrieval based domain independent sentiment; analysis framework that uses customized pattern matching techniques, such as nave bayesian filter, bag of words and part of speech tagging are used for opinion extraction in blogs. We also developed prototype two-panel and four-panel search applications of the query results. In addition, we also analyze opinionated sentences to identify trends on the hot and top topics. The modular framework of of Blogvox2 provides a platform where new modules for different domains can be easily plugged in. The framework provides the date of publishing, permanent link and the urls of the sentences that expresses opinions based on the analysis. Based on the analysis of the blogvox2 on political domain, our system performs well with unigram approach. We investigated our framework with pattern matching techniques, bigram technique, combining the unigram and bigram techiniques and incorporating parts of speech tagging, which have not fared as well as unigram techniques. We also investigated the reasons for the performance degradation or enhancements on each approach. Based on our analysis, we developed different applications to ease the use of our framework.

description: We prove uniform bounds on moments X_a = \sum_{m}{m^a f_m(x,t)} of the Smoluchowski coagulation equations with diffusion, valid in any dimension. If the collision propensities α(n,m) of mass n and mass m particles grow more slowly than (n+m)(d(n) + d(m)), and the diffusion rate d(\cdot) is non-increasing and satisfies m^{-b_1} \leq d(m) \leq m^{-b_2} for some b_1 and b_2 satisfying 0 \leq b_2 < b_1 < \infty, then any weak solution satisfies X_a \in L^{\infty}(\mathbb{R}^d \times [0,T]) \cap L^1(\mathbb{R}^d \times [0,T]) for every a \in \mathbb{N} and T \in (0,\infty), (provided that certain moments of the initial data are finite). As a consequence, we infer that these conditions are sufficient to ensure uniqueness of a weak solution and its conservation of mass.

description: When persons are mentioned in texts with their first name, last name and/or middle names, there can be a high variation which of their names are used, how their names are ordered and if their names are abbreviated. If multiple persons are mentioned consecutively in very different ways, especially short texts can be perceived as "messy". Once ambiguous names occur, associations to persons may not be inferred correctly. Despite these eventualities, in this paper we ask how well an unsupervised algorithm can build a person index from short texts. We define a person index as a structured table that distinctly catalogs individuals by their names. First, we give a formal definition of the problem and describe a procedure to generate ground truth data for future evaluations. To give a first solution to this challenge, a baseline approach is implemented. By using our proposed evaluation strategy, we test the performance of the baseline and suggest further improvements. For future research the source code is publicly available.

description: Cloud-cloud collision (CCC) has been suggested as a mechanism to induce massive star formation. Recent simulations suggest that a CCC speed is different among galactic-scale environments, which is responsible for observed differences in star formation activity. In particular, a high-speed CCC is proposed as a cause of star formation suppression in the bar regions in barred spiral galaxies. Focusing on the strongly barred galaxy NGC1300, we investigate the CCC speed. We find the CCC speed in the bar and bar-end tend to be higher than that in the arm. The estimated CCC speed is $\sim20~\rm km~s^{-1}$, $\sim16~\rm km~s^{-1}$, and $\sim11~\rm km~s^{-1}$ in the bar, bar-end, and arm, respectively. Although the star formation activity is different in the bar and bar-end, the CCC speed and the number density of high-speed CCC with $> 20~\rm km~s^{-1}$ are high in both regions, implying the existence of other parameters that control the star formation. The difference in molecular gas mass (average density) of the giant molecular clouds (GMCs) between the bar (lower mass and lower density) and bar-end (higher mass and higher density) may be cause for the different star formation activity. Combining with our previous study (Maeda et al.), the leading candidates of causes for the star formation suppression in the bar in NGC1300 are the presence of a large amount of diffuse molecular gases and high-speed CCCs between low mass GMCs.

description: The purpose of the present study was to examine the potential relation between depressive symptomatology and cardiovascular disease (CVD)-related inflammatory biomarkers in participants enrolled in the Healthy Aging in Neighborhoods of Diversity across the Lifespan Study (HANDLS). 2459 participants aged to 64 years old (M = 48 years, SD = 9.3) completed the completed the Center for Epidemiological Studies Depression scale (CES-D) and underwent blood draws to assess levels of white blood cells (WBCs). A subset of these participants (n = 210) were also assessed for levels of cytokines and C-reactive protein (CRP). The main analyses set consisted of multiple regressions with an aggregated CES-D score and the CES-D subscales of negative affect, positive affect, somatic complaints, and interpersonal relationship problems (entered separately) as predictors of CRP, total WBC count, neutrophil count, lymphocyte count, Il-1b, Il-6, Il-10, and TNF-α. Additional exploratory analyses were stratified by sex and contained CES-D score by race by poverty status interaction terms.   Controlling for standard cardiovascular risk factors, results indicated no association between CES-D total score and the biomarkers; limited associations between CES-D subscales and the biomarkers, such that somatic complaints predicted WBCs and interpersonal relationship problems predicted Il-10; and complex associations between CES-D subscales, socio-demographic characteristics, and inflammatory biomarkers. It is concluded that the relation between depression and inflammation is complex and underlying pathophysiological mechanisms may distinctly differ across various population groups.
