description: We study the effects of inelastic dark matter self-interactions on the internal structure of a simulated Milky Way (MW)-size halo. Self-interacting dark matter (SIDM) is an alternative to collisionless cold dark matter (CDM) which offers a unique solution to the problems encountered with CDM on sub-galactic scales. Although previous SIDM simulations have mainly considered elastic collisions, theoretical considerations motivate the existence of multi-state dark matter where transitions from the excited to the ground state are exothermic. In this work, we consider a self-interacting, two-state dark matter model with inelastic collisions, implemented in the Arepo code. We find that energy injection from inelastic self-interactions reduces the central density of the MW halo in a shorter timescale relative to the elastic scale, resulting in a larger core size. Inelastic collisions also isotropize the orbits, resulting in an overall lower velocity anisotropy for the inelastic MW halo. In the inner halo, the inelastic SIDM case (minor-to-major axis ratio $s \equiv c/a \approx 0.65$) is more spherical than the CDM ($s \approx 0.4$), but less spherical than the elastic SIDM case ($s \approx 0.75$). The speed distribution $f(v)$ of dark matter particles at the location of the Sun in the inelastic SIDM model shows a significant departure from the CDM model, with $f(v)$ falling more steeply at high speeds. In addition, the velocity kicks imparted during inelastic collisions produce unbound high-speed particles with velocities up to 500 km s$^{-1}$ throughout the halo. This implies that inelastic SIDM can potentially leave distinct signatures in direct detection experiments, relative to elastic SIDM and CDM.

description: Esta dissertação almeja investigar, a partir da articulação entre a estruturação das séries
 sequenciais e as técnicas narrativas, de que forma a construção narrativa pode se tornar um
 jogo para o espectador, na série Westworld (2016). Desta forma, é proposto como metodologia
 o desenvolvimento de uma pesquisa bibliográfica, sendo a organização do estudo feita por
 meio da produção de três capítulos. No primeiro capítulo é discutida a diferença entre série
 episódica e série sequencial. Além disso, é feito um comparativo entre a série Westworld
 (2016) e o filme Westworld (1973). No segundo capítulo é feita uma investigação sobre como
 as temporadas de Westword (2016) podem ser analisadas a partir dos conceitos de
 imagem-movimento e imagem-tempo criados pelo filósofo Gilles Deleuze. Também são
 aprofundados os conceitos de imagem-afecção, imagem-percepção, imagem-ação,
 imagem-lembrança e imagem-cristal. No terceiro capítulo visa-se entender de que maneira
 Westworld (2016) se utiliza das técnicas narrativas de cliffhanger e plot twist para estabelecer
 a narrativa elíptica da primeira e da segunda temporada. Pondera-se o marketing utilizado
 para a divulgação da segunda temporada da série e apura-se o engajamento e a receptividade
 dos fãs quanto às temporadas produzidas. Dessa forma, no primeiro capítulo estudamos o
 formato de série sequencial em teoria, no segundo capítulo assimilamos as técnicas narrativas
 que embasam o formato sequencial na prática, e no terceiro capítulo detectamos como essa
 construção cria um jogo para o espectador, considerando a visão dos fãs sobre essa proposta -
 respondendo, assim, ao problema que guia esta dissertação.

description: In this paper, we propose a method to adapt a general parser (Link Parser) to sublanguages, focusing on the parsing of texts in biology. Our main proposal is the use of terminology (identication and analysis of terms) in order to reduce the complexity of the text to be parsed. Several other strategies are explored and finally combined among which text normalization, lexicon and morpho-guessing module extensions and grammar rules adaptation. We compare the parsing results before and after these adaptations.

description: The topic of climate change garners much attention in society; however, most discussions on the subject refer only to global warming and its effects on sea levels, increases in tropical diseases, or increases in severe weather events. These mentioned effects are only one side of a multi-faceted phenomenon. Another equally important facet is the effect it can have on the oceans. At current atmospheric CO2 levels, it is thought that the oceans absorb approximately 40% of the fossil fuel related CO2 emissions. According to several models, we are poised to change the ocean's pH more in the next 300 years than in the last 300 million years. Although there are several devices and technologies that can monitor dissolved oceanic CO2, there are none that are small or affordable enough to deploy in appropriate numbers to adequately monitor the earth's oceans. This fact coupled with the lack of sufficient oceanic data for dissolved CO2 mandates another sensor's development - ours. Our sensor is based on the change in fluorescence of the pH sensitive indicator 8 - Hydroxypyrene - 1,3,6 - trisulfonic acid, trisodium salt (HPTS) in solution due to the diffusion of dissolved CO2 across a gas permeable Teflon AF membrane.  Our device, which in controlled settings has approached the +/- 2 ppm  limit required by the Large-Scale CO2 Observing Plan: In Situ Oceans and Atmosphere mandate, was kept affordable and small by employing emerging fabrication technologies in microfluidics and our partnership with Fluorometrix (Stowe, MA) , a leader in uFluorometer technologies.

description: Researchers emphasize the need for early universal prevention of youth externalizing problems. Preschool disruptive behaviors are associated with ongoing social and academic functioning, especially in low-income families. Recently, preschool social-emotional learning (SEL) programs have demonstrated promising social outcomes. The present study was a randomized trial of a new SEL program (GOALS) designed to expand outcomes related to school readiness. GOALS builds on existing programs through increased emphasis on social information processing (SIP) and executive functioning (EF), video-based lessons, and practical teacher generalization strategies. I conducted repeated measures ANOVAs to examine pre-post change in SIP, EF, and disruptive behavior. There was partial support for one of six hypotheses; GOALS had a strong effect on teacher-reported self-control. Non-hypothesized higher-order interactions suggest that GOALS may impact girls' and older children's aggression-related social cognitions and more verbal children's attention difficulties. Further evaluations are needed to determine GOALS' efficacy and the nature of subgroup effects.

description: Machine Learning has proved its ability to produce accurate models but the deployment of these models outside the machine learning community has been hindered by the difficulties of interpreting these models. This paper proposes an algorithm that produces a continuous global interpretation of any given continuous black-box function. Our algorithm employs a variation of projection pursuit in which the ridge functions are chosen to be Meijer G-functions, rather than the usual polynomial splines. Because Meijer G-functions are differentiable in their parameters, we can tune the parameters of the representation by gradient descent; as a consequence, our algorithm is efficient. Using five familiar data sets from the UCI repository and two familiar machine learning algorithms, we demonstrate that our algorithm produces global interpretations that are both highly accurate and parsimonious (involve a small number of terms). Our interpretations permit easy understanding of the relative importance of features and feature interactions. Our interpretation algorithm represents a leap forward from the previous state of the art.

description: Changes in the demographics of the United States have resulted in growing numbers of minorities.  Unfortunately, the field of psychology has failed to reflect these changes in the diversity of the academic student body and the national workforce.  To ensure that the needs of the United States' increasingly diverse population are addressed through both culturally and linguistically competent research and practice, it is imperative to increase the racial/ethnic diversity among psychologists.  This study explores the ways in which a national sample of undergraduate students, from various racial/ethnic groups, are similar and different in their perceptions of support, barriers, perception of diversity, monetary considerations, satisfaction with their studies in psychology, and intention to pursue a graduate degree in psychology, and in the interrelationships among these variables. The findings revealed a positive relationship for all students between academic support and satisfaction with studies and a negative relationship between academic barriers and satisfaction with studies.  There was also evidence of an interaction between race/ethnicity and the perception of diversity in the academic environment on satisfaction with studies in psychology.  Specifically, African American students' reports of satisfaction with studies in psychology were related to their perceptions of the extent of cultural diversity in their academic environment to a greater extent than European American students.  In addition, academic support was positively related to intention to pursue an advanced degree in psychology; however, there was no relationship between the other psychosocial predictor variables and intention. Hypothesized ethnic group differences were found related to loan status and satisfaction with studies in psychology.  In regards to loan status, African Americans were significantly more likely to rely on loans as their only form of financial support compared to European Americans, and on loans combined with other financial support compared to all three racial/ethnic groups.  Finally, African Americans and Asian Americans were significantly less satisfied with their studies in psychology than their European American peers.  Overall, the current study's findings contribute to our understanding of important factors related to enhancing diversity in psychology and provide additional support for the critical role of academic support related to educational outcomes.

description: The Mom Community on YouTube consists of a large group of parents who share their parenting beliefs and experiences to connect and share information with others. Although there is a lot of positive support in this community, it is often a hotspot for debate of controversial parenting topics. Many of these topics have one side that represents the belief of crunchy moms. Crunchy is a term used to describe parents who intentionally choose natural parenting methods and eco-friendly products to raise their children. Debate over these practices has led to mompetition and the idea that there is a right way to parent. This research investigates questions such as how different crunchy topics are discussed and how the community has changed over time. Video comments and user data are collected from YouTube and used to understand parenting practices and opinions in the mom community. Results show that YouTube data can be used for understanding communities based on comment interactions. Content creators are shown to be crunchier than viewers for selected parenting topics. The mom community has low reciprocity and network structure similar to other social networking sites.

description: The cornerstone of filesystem security in UNIX-like operating systems is the paradigm of users and groups. Each file has an associated user and group which identifies the who has ownership rights to the file. While the idea of user and group ownership of files has been extended by access control lists, it has remained relatively unchanged even as security needs have vastly changed. This research addresses ownership of files in a manner that extends the current model while remaining compatible with the vast majority of available software for UNIX-like operating systems. We have implemented a multilevel hierarchical extension of both users and groups as an extension to the normal single-level UNIX model. We minimized the changes required to user-space applications in order to remain compatible with the vast array of software available for UNIX-like operating systems. The implementation of this research was conducted on the MINIX 3 operating system, with an emphasis on portability to other UNIX-like operating systems in the future. The result of this research is a series of modifications to various operating system server programs to implement our hierarchical permissions model and to enforce the model when loading applications and accessing files in the system.

An econometric analysis of the demand for wood products in Japan by product type, species, and source
Creators: name: Gaston, Christopher Willem
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the Japanese demand for wood by product type, by country of origin, and by species, over the period 1965 to 1993. The product types include softwood and hardwood logs, softwood and hardwood lumber, and wood-based panel products (plywood, fibreboard and particle board). In addition to estimating the own-price effects on quantity demanded for individual wood product imports, substitution effects within these product categories are documented to the degree possible, including Japanese substitution with domestic product and non-wood alternatives. The research makes two important contributions. The first is to offer Japanese demand descriptors at a level of wood product detail which is not found in the existing literature. The second is to review and critique the existing methodologies available for investigating substitution effects among disaggregated products (such as softwood lumber by species). As it was discovered that the available approaches are inadequate for properly dealing with product detail, strong recommendations for further research are made for improving our ability to document cross-price effects. The primary conclusion of the study is that individual wood products, by product type, by country of origin, or by species, behave as distinct economic units. This suggests that studies which aggregate wood products into broad categories such as "softwood lumber" risk obscuring important dimensions of both forest products' trade and forest policy.

description: Minkowski functionals (MFs) are a set of statistics that characterise the geometry and topology of the cosmic density field and contain complementary information to the standard two-point analyses. We present MEDUSA, an implementation of an accurate method for estimating the MFs of three-dimensional point distributions. These estimates are inferred from triangulated isodensity surfaces that are constructed from the Delaunay tessellation of the input point sample. Contrary to previous methods, MEDUSA can account for periodic boundary conditions, which is crucial for the analysis of N-body simulations. We validate our code against several test samples with known MFs, including Gaussian random fields with a $Λ$CDM power spectrum, and find excellent agreement with the theory predictions. We use MEDUSA to measure the MFs of synthetic galaxy catalogues constructed from N-body simulations. Our results show clearly non-Gaussian signatures that arise from the non-linear gravitational evolution of the density field. We find that, although redshift-space distortions significantly change our MFs estimates, their impact is considerably reduced if these measurements are expressed as a function of the volume-filling fraction. We also show that the effect of Alcock-Paczynski (AP) distortions on the MFs can be described by scaling them with different powers of the isotropic AP parameter $q$ defined in terms of the volume-averaged distance $D_{\rm V}(z)$. Thus the MFs estimates by MEDUSA are useful probes of non-linearities in the density field, and the expansion and growth of structure histories of the Universe.

description: Context: We report new polarization measurements of the variable near-infrared emission of the SgrA* counterpart associated with the massive 3--4 10^6 solar masses Black Hole at the Galactic Center. Aims: We investigate the physical processes responsible for the variable emission from SgrA*. Methods: The observations have been carried out using the NACO adaptive optics (AO) instrument at the European Southern Observatory's Very Large Telescope Results: We find that the variable NIR emission of SgrA* is highly polarized and consists of a contribution of a non- or weakly polarized main flare with highly polarized sub-flares. The flare activity shows a possible quasi-periodicity of 20+-3 minutes consistent with previous observations. Conclusions: The highly variable and polarized emission supports that the NIR emission is non-thermal. The observations can be interpreted in a jet or temporary disk model. In the disk model the quasi-periodic flux density variations can be explained due to spots on relativistic orbits around the central MBH. Alternative explanations for the high central mass concentration involving boson or fermion balls are increasingly unlikely.

Stress in a Model of Adolescent Risk

description: Adolescent engagement in risk taking is a public health concern, given the  increase in risk- taking behaviors during this developmental period and the  possibility for negative outcomes ( e. g., drug abuse or death). This study  attempted to develop a model of risk- taking propensity, as indicated by a  naturalistic assessment paradigm, in inner- city African American adolescents  ( N = 108) who were prenatally drug- exposed or non- exposed using  psychological and physiological stress indicators. The stress indicators used  were caregiver and adolescent psychological stress, as indicated by self-report,  and adolescent physiological stress, as indicated by cortisol. The  study used cross- sectional and longitudinal data to examine the unique  prediction or risk- taking propensity and the structural relations of the variables  of interest with risk- taking propensity. The relations of the variables of  interest with risk- taking propensity were limited, but did vary considerably by  sex and status of prenatal drug exposure, which suggests that the theory of  stress in adolescent risk is still tenable. Future research with more  appropriate indicators of stress and larger samples to adequately test for  interactions are necessary. Continuing efforts to identify predictors of  adolescent risk- taking are necessary to identify variables that are amenable  to interventions which can prevent or reduce the negative consequences of  engagement in risk- taking behavior.

Using two biomedical corpora, we implement and evaluate three approaches to addressing unknown words: automatic lexicon expansion, the use of morphological clues, and disambiguation using a part-of-speech tagger. We evaluate each approach separately for its effect on parsing performance and consider combinations of these approaches. In addition to a 45% increase in parsing efficiency, we find that the best approach, incorporating information from a domain part-of-speech tagger, offers a statistically signicant 10% relative decrease in error. The adapted parser is available under an open-source license at http://www.it.utu.fi/biolg.

We find that an oscillation along the rotation axis is induced throughout the growth of the unstable bar mode, and that its characteristic frequency is twice as that of the bar mode, which oscillates mainly along the equatorial plane. A possibility to observe Faraday resonance in gravitational waves is demonstrated and discussed.

Analysis of Routing and Wavelength Assignment in Large WDM Networks
Creators: name: KOGANTI, RAVI TEJA
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: In Wavelength Division Multiplexing (WDM) network, for a given connection request, a route has to be found, and a dedicated wavelength has to be assigned along that route. This problem of assigning route and wavelength to the connection request, using minimum network resources, is called Routing and Wavelength Assignment (RWA) Problem. This thesis focuses on the analysis of proposed RWA algorithms in large WDM networks. We use simulations and analysis of randomly generated large networks under dynamic traffic and static traffic, with and without protection of the connection request. The protection of the primary route between source and destination is considered by setting up a dedicated backup path in case of failures.  The wavelength requirements are analyzed using different wavelength assignment heuristics under different routing techniques for a set of connection requests. We find that, the fixed alternate routing packs the connection requests into less number of wavelengths than the fixed routing and most-used performs slightly better than the first-fit heuristic.

description: An excess $γ$-ray signal toward the outer halo of M31 has recently been reported. Although other explanations are plausible, the possibility that it arises from dark matter (DM) is valid. In this work we interpret the excess in the framework of DM annihilation, using as our representative case WIMP DM annihilating to bottom quarks, and we perform a detailed study of the systematic uncertainty in the $J$-factor for the M31 field. We find that the signal favors a DM particle with a mass of $\sim$46-73 GeV. While the mass is well constrained, the systematic uncertainty in the cross-section spans 2.5 orders of magnitude, ranging from $\sim$8$\times 10^{-27}-4 \times 10^{-24} \ \mathrm{cm^3 \ s^{-1}}$. This high uncertainty is due to two main factors, namely, an uncertainty in the substructure nature and geometry of the DM halos for both M31 and the Milky Way (MW), and correspondingly, an uncertainty in the contribution to the signal from the MW's DM halo along the line of sight. However, under the conditions that the minimum subhalo mass is $\lesssim 10^{-6} \ M_\odot$ and the actual contribution from the MW's DM halo along the line of sight is at least $\sim$30$\%$ of its total value, we show that there is a large overlap with the DM interpretations of both the Galactic center (GC) excess and the antiproton excess, while also being compatible with the limits for the MW dwarf spheroidals. More generally, we summarize the results from numerous complementary DM searches in the energy range 10 GeV $-$ 300 GeV corresponding to the GC excess and identify a region in parameter space that still remains viable for discovery of the DM particle.

Vobfus

description: Visual Basic platform is increasingly becoming popular amongst malware authors. This is due to the fact, Visual Basic malwares are more complicated to analyze and it can be used to avoid precise detection by most antiviruses. Conventional tools like IDA Pro and OllyDbg do not provide much help when it comes to analyzing Visual Basic binaries. Along with this, a malware author can add self-defined algorithms for obfuscation and encryption. This combination allows the malware authors to create a malware that would be difficult to discover and analyze. This study mainly focuses on the growing impact of Visual Basic binaries in the world of malware. Our major malware for discussion would be Vobfus, which is a VB-obfuscated sample that connects to a server to download other malware to the victim's machine. The analysis of Vobfus would be accompanied with analysis of a few other Visual Basic malware samples. In the end, a critique of the conventional malware analysis tools while analyzing Visual Basic malwares would be presented.

description: This study utilized 570 participants from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN) to explore sex differences in the development of late childhood aggression and delinquency. Multiple risk factors, organized according to Brofenbrenner's ecological perspective, were analyzed individually and as a group. Risk factors included child IQ, child attentional issues, discipline practices, interpersonal personal violence (IPV), child sexual abuse, family functioning, neighborhood violence, and neighborhood characteristics. Significant sex interactions were found for discipline practices, IPV, and family functioning for both aggression and delinquency, such that effects were significant for males, but not females.

description: There has been much debate over whether or not one could explain the observed acceleration of the Universe with inhomogeneous cosmological models, such as the spherically-symmetric Lemaitre-Tolman-Bondi (LTB) models. It has been claimed that the central observer in these models can observe a local acceleration, which would contradict general theorems. We resolve the contradiction by noting that many of the models that have been explored contain a weak singularity at the location of the observer which makes them unphysical. In the absence of this singularity, we show that LTB models must have a positive central deceleration parameter $q_{0}$, in agreement with the general theorems. We also show that it is possible to achieve a negative apparent deceleration parameter at nonzero redshifts in LTB models that do not contain this singularity. However, we find other singularities that tend to arise in LTB models when attempting to match luminosity distance data, and these generally limit the range of redshifts for which these models can mimic observations of an accelerating Universe. Exceptional models do exist that can extend to arbitrarily large redshift without encountering these pathologies, and we show how these may be constructed. These special models exhibit regions with negative effective equation of state parameter, which may fall below negative one, but we have failed to find any singularity-free models that agree with observations. Moreover, models based on dust-filled LTB metrics probably fail to reproduce observed properties of large scale structure.

description: In order to withstand the ever-increasing invasion of privacy by CCTV cameras and technologies, on par CCTV-aware solutions must exist that provide privacy, safety, and cybersecurity features. We argue that a first important step towards such CCTV-aware solutions must be a mapping system that provides both privacy and safety routing and navigation options. To the best of our knowledge, there are no mapping nor navigation systems that support privacy and safety routing options. In this paper, we explore the feasibility of a CCTV-aware routing and navigation solution. The aim of this feasibility exploration is to understand what are the main impacts of CCTV on privacy, and what are the challenges and benefits to building such technology. We evaluate our approach on seven (7) pedestrian walking routes within the downtown area of the city of Jyvaskyla, Finland. We first map a total of 450 CCTV cameras, and then experiment with routing and navigation under several different configurations to coarsely model the possible cameras' parameters and coverage from the real-world. We report two main results. First, our preliminary findings support the overall feasibility of our approach. Second, the results also reveal a data-driven worrying reality for persons wishing to preserve their privacy/anonymity as their main living choice. When modelling cameras at their low performance end, a privacy-preserving route has on average a 1.5x distance increase when compared to generic routing. When modelling cameras at their medium-to-high performance end, a privacy-preserving route has on average a 5.0x distance increase, while in some cases there are no privacy-preserving routes possible at all. These results further support and encourage both global mapping of CCTV cameras and refinements to camera modelling and underlying technology.

description: Future detectors for high luminosity particle identification and ultra high energy neutrino observation would benefit from a digitizer capable of recording sensor elements with high analog bandwidth and large record depth, in a cost-effective, compact and low-power way. A first version of the Buffered Large Analog Bandwidth (BLAB1) ASIC has been designed based upon the lessons learned from the development of the Large Analog Bandwidth Recorder and Digitizer with Ordered Readout (LABRADOR) ASIC. While this LABRADOR ASIC has been very successful and forms the basis of a generation of new, large-scale radio neutrino detectors, its limited sampling depth is a major drawback. A prototype has been designed and fabricated with 65k deep sampling at multi-GSa/s operation. We present test results and directions for future evolution of this sampling technique.

The Red Supergiant Binary Fraction as a Function of Metallicity in M31 and M33

description: Recent work measuring the binary fraction of evolved red supergiants (RSGs) in the Magellanic Clouds points to a value between 15-30%, with the majority of the companions being un-evolved B-type stars as dictated by stellar evolution. Here I extend this research to the Local Group galaxies M31 and M33, and investigate the RSG binary fraction as a function of metallicity. Recent near-IR photometric surveys of M31 and M33 have lead to the identification of a complete sample of RSGs down to a limiting $\log L/L_{\odot} \geq 4.2$. To determine the binary fraction of these M31 and M33 RSGs, I used a combination of newly obtained spectroscopy to identify single RSGs and RSG+OB binaries as well as archival UV, visible and near-IR photometry to probabilistically classify RSGs as either single or binary based on their colors. I then adjusted the observed RSG+OB binary fraction to account for observational biases. The resulting RSG binary fraction in M33 shows a strong dependence on galactocentric distance with the inner regions having a much higher binary fraction ($41.2^{+12.0}_{-7.3}$%) than the outer regions ($15.9^{+12.4}_{-1.9}$%). Such a trend is not seen in M31; instead, the binary fraction in lightly reddened regions remains constant at $33.5^{+8.6}_{-5.0}$%. I conclude the changing RSG binary fraction in M33 is due to a metallicity dependence with higher metallicity environments having higher RSG binary fractions. This dependence most likely stems not from changes in the physical properties of RSGs due to metallicity, but changes in the parent distribution of OB binaries.
