Mental Simulation of the Imminent Future
Creators: name: Vannia Alexandra Puig Rivera
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Research on simulating the future has garnered much attention from cognitive psychologists, especially over the last decade. Extant work has demonstrated that projecting oneself into the future can have beneficial effects on the individual, such as allowing them to ponder decisions and plan actions. However, in this project I address a potential oversight in the literature; namely, the conceptualization of what classifies as a future moment. Indeed, an analysis of the future thinking literature illustrates that the future is commonly understood as an event that takes place at a different time and location than the present moment. Nonetheless, I propose that an additional time-frame of the future exists and merits experimental attention. Specifically, I put forth the notion of mental simulation of the imminent future, which is a time point both spatially and temporally linked to the moment in which the simulation is taking place. In addition to grounding the concept of the imminent future within the extant research on future thinking, I also provide preliminary evidence suggesting that simulations of the imminent future are characteristically and functionally different from simulations of the future that occur in a time and place that is removed from the present moment (i.e., the delayed future). Finally, I present data from a diary study that provides novel insights into the differences between simulations of the imminent and delayed future.

v4 for identified particles at RHIC from viscous hydrodynamics

description: Using ideal and viscous hydrodynamics, the ratio of azimuthal moments v4/(v2)^2 is calculated for pions, protons, and kaons in sqrt{s}=200 A*GeV Au+Au collisions. For any value of viscosity here is little dependence on particle species. Ideal hydrodynamics and data show a flat curve as a function of pt. Adding viscosity in the standard way destroys this flatness. However, it can be restored by replacing the standard quadratic ansatz for delta f (the viscous correction to the distribution function at freeze-out) with a weaker momentum dependence.

Tweens, teens, and digital texts : designing affinity spaces to understand cyberbullying
Creators: name: Liu, Lesley Edana
Publisher: name: University of British Columbia
Year: 2016

description: This research explores how adolescents design, interpret, and navigate affinity spaces in connection to cyberbullying awareness. A class of Grade 8 students (aged 12-13, mixed gender, and a variety of digital skills) (n=28) participated in the study. The participants first investigated the use of affinity spaces, collaborative physical and digital spaces (Gee, 2005), then proceeded to design their own spaces for collaborative group work. A variety of data were collected in the form of peer-to-peer pre interviews, OneNote collaborative group journals, in-class observations of class work sessions, and post interviews. The methodologies used include case study, design-based research, and ethnographic techniques. This research was conducted in six stages and in a total of 15 hours; certain stages were allotted extra work sessions to accommodate the speed of the students’ progress. Stages three to five overlapped and occurred simultaneously as students designed, tried, re-examined and compared other applications, then re-evaluated their designs. The findings of this study inform how adolescents design affinity spaces (real and virtual) and emphasize design features to serve as functioning collaborative workspaces, both in and out of the classroom, to prevent or counter cyberbullying. Findings related to how students design affinity spaces for collaborative work emerged in three themes: Group Presence, Individual Digital Space, and Guidelines for Clarity. Student-informed or student-designed spaces provide a sense of ownership or and self-regulation and give insight as to how codes of conduct inform these spaces and vice versa. Future studies should adopt an iterative process of design-based research to test and refine these affinity spaces (Collins et al., 2004; Wang, Petrina, & Feng, 2015). Recommendations also include future applications of sociocultural theory and activity theory to discern how adolescents differentiate between face-to-face and online communication and practical classroom applications of affinity spaces in secondary schools.

description: A recently proposed "DFT+dispersion" treatment (Rajchel et al., Phys. Rev. Lett., 2010, 104, 163001) is described in detail and illustrated by more examples. The formalism derives the dispersion-free density functional theory (DFT) interaction energy and combines it with the dispersion energy from separate DFT calculations. It consists in the self-consistent polarization of DFT monomers restrained by the exclusion principle via the Pauli blockade technique. Within the monomers a complete exchange-correlation potential should be used, but between them only the exact exchange operates. The applications to wide range of molecular complexes from rare-gas dimers to H-bonds to pi-electron interactions show good agreement with benchmark values.

description: We present a wide-field H-alpha imaging survey of the rich cluster CL0939+4713 (Abell 851) at z=0.41 with Suprime-Cam on the Subaru Telescope, using the narrow-band filter NB921. The survey is sensitive to active galaxies with star formation rates down to ~0.3Msun/yr throughout the 27'x27' field, and we identified 445 H-alpha emitters along the large-scale structures around the cluster. Using this sample, we find that (1) the fraction of H-alpha emitters is a strong function of environment and shows a clear decline toward the cluster central region. We also find that (2) the color of H-alpha emitters is clearly dependent on environment. The majority of the H-alpha emitters have blue colors with B-I<2, but we find H-alpha emitters with red colors as well. Such red emitters are very rare in the cluster center or its immediate surrounding regions, while they are most frequently found in groups located far away from the cluster center. These groups coincide with the environment where a sharp transition in galaxy color distribution is seen. This may suggest that dusty star formation activity tends to be involved in galaxy truncation processes that are effective in groups, and it is probably related to the "pre-processing" that generates present-day cluster S0 galaxies. Finally, we confirm that (3) the mass-normalized integrated star formation rate in clusters (i.e. the total star formation rate within 0.5xR200 from the cluster center divided by the cluster dynamical mass) rapidly increases with look-back time following approximately ~(1+z)^6, and it is also correlated with the cluster mass.

description: We show that long-ranged superconducting order is not necessary to guarantee the existence of Majorana fermion zero modes at the ends of a quantum wire. We formulate a concrete model which applies, for instance, to a semiconducting quantum wire with strong spin-orbit coupling and Zeeman splitting coupled to a wire with algebraically-decaying superconducting fluctuations. We solve this model by bosonization and show that it supports Majorana fermion zero modes. We argue that a large class of models will also show the same phenomenon. We discuss the implications for experiments on spin-orbit coupled nanowires coated with superconducting film and for LaAlO3/SrTiO3 interfaces.

description: We classify bounded t-structures on the category of perfect complexes over a commutative, Noetherian ring of finite Krull dimension, extending a result of Alonso Tarrio, Jeremias Lopez and Saorin which covers the regular case.

description: We present near-infrared photometry and spectroscopy, and warm-Spitzer IRAC photometry of the young very cool T dwarf Ross 458C, which we have typed as T8.5p. By applying the fiducial age constraints (< 1Gyr) imposed by the properties of the active M dwarf Ross 458A, we have used these data to determine that Ross 458C has Teff = 695 \pm 60K, log g = 4.0 - 4.7 and an inferred mass of 5-20 MJup. We have compared fits of the near-infrared spectrum and IRAC photometry to the BT Settl and Saumon & Marley model grids, and have found that both sets provide best fits that are consistent with our derived properties, whilst the former provide a marginally closer match to the data for all scenarios explored here. The main difference between the model grids arises in the 4.5μm region, where the BT Settl models are able to better predict the flux through the IRAC filter, suggesting that non-equilibrium effects on the CO-CO2 ratio are important for shaping the mid-infrared spectra of very cool T dwarfs. We have also revisited the issue of dust opacity in the spectra of Ross 458C that was raised by Burgasser et al (2010). We have found that the BT Settl models which also incorporate a condensate cloud model, provide a better match to the near-infrared spectrum of this target than the Saumon & Marley model with fsed = 2, and we briefly discuss the influence of condensate clouds on T dwarf spectra.

description: The structural parameters of the disk of the Large Magellanic Cloud (LMC) are estimated.We used the red clump stars from the VI photometric data of the Optical Gravitational Lensing Experiment survey and from the Magellanic Cloud Photometric Survey for the estimation of inclination and position angle of line of nodes of the LMC disk. The dereddened peak I magnitude of the red clump stars in each subregion is used to obtain the relative distances and hence the z coordinate. The RA and Dec of each sub-region is converted into x & y cartesian coordinates. A weighted least square plane fitting method is applied to this x,y,z data to estimate the structural parameters of the LMC disk. We find an inclination of i =23.0 plus or minus 0.8 and PAlon = 163.7 plus or minus 1.5 for the LMC disk using the OGLE III data and an inclination of i=37.4 plus or minus 2.3 and PAlon= 141.2 plus or minus 3.7 for the LMC disk using the MCPS data. The effect of choice of center, reddening and area covered on the estimated parameters are discussed. Regions in the north west, south west and south east of the LMC disk are warped with respect to the fitted plane. We also identify a symmetric but offcentered warp in the inner LMC.We identify that the structure of the LMC disk inside the 3 degree radius is different from the outside disk such that the inner LMC has relatively less inclination and relatively large PAlon. The 3D plot of the LMC disk suggests an offcentered increase in the inclination for the north-eastern regions which might be due to tidal effects. We suggest that the variation in the planar parameters estimated by various authors as well as in this study is because of the difference in coverage and the complicated inner structure of the LMC disk. In the inner LMC, the stellar and HI disk are found to have similar properties.

Gothic is the New Iraq

description: Born after the second U.S. invasion, the Iraqi gothic originated in response to the chaotic war and its aftermath, along with the political, religious and social changes in the region. The psychology and mentality of Iraqis changed in the decades after the invasion. Daily life became a tableau of public deaths, explosions, burning and revenge with the cadavers that resulted from kidnapping and torture, littering Baghdad’s streets. Amidst the waking nightmares, the gothic emerged as a way for writers to express novel forms of fear and horror, in response to an endless cycle of oppression and sectarian war. Gothic introduced to the Iraqi literature new settings, different themes and characters. It struggled to appear, but once it’s there, gothic float over the products of the Iraqi fiction since 2007. The list of the gothic texts is growing rapidly and writers old and new see it as a new obsession. It is for the first time that writers criticize law, voice fear and negotiate life and death. My purpose here is to provide a clear definition of the Iraqi gothic fiction, followed by major representative texts. All the tempts here is to honor the need for an understanding of the rise of this particular form of fiction in Iraq at this time.

description: The generalization of the Dorokhov-Mello-Pereyra-Kumar equation for the description of transport in strongly disordered systems replaces the symmetry parameter $β$ by a new parameter $γ$, which decreases to zero when the disorder strength increases. We show numerically that although the value of $γ$ strongly influences the statistical properties of transport parameters $Δ$ and of the energy level statistics, the form of their distributions always depends on the symmetry parameter $β$ even in the limit of strong disorder. In particular, the probability distribution is $p(Δ)\sim Δ^β$ when $Δ\to 0$ and $p(Δ) \sim \exp (-cΔ^2)$ in the limit $Δ\to\infty$.

We show that below some threshold value of anticonformal behavior spontaneous reorientations occur between two stable states. Dealing with a complete graph allows us also for analytical treatment. We show that opinion dynamics can be understood as a movement of a public opinion in a symmetric bistable effective potential. We focus also on the spontaneous transitions between stable states and show that a typical waiting time can be observed.

description: We have discovered a binary AGN in the galaxy Mrk 739 using Chandra and Swift BAT. We find two luminous L_2-10 keV=1.1*10^43 and 1.0*10^42 erg/s, unresolved nuclei with a projected separation of 3.4 kpc (5.8\pm0.1) coincident with two bulge components in the optical image. The western X-ray source (Mrk 739W) is highly variable (2.5x) during the 4-hour Chandra observation and has a very hard spectrum consistent with an AGN. While the eastern component was already known to be an AGN based on the presence of broad optical recombination lines, Mrk 739W shows no evidence of being an AGN in optical, UV, and radio observations, suggesting the critical importance of high spatial resolution hard X-ray observations (>2 keV) in finding these binary AGN. A high level of star formation combined with a very low L_[O III]/L_2-10 keV ratio cause the AGN to be missed in optical observations. CO observations of the (3-2) and (2-1) lines indicate large amounts of molecular gas in the system that could be driven towards the black holes during the violent galaxy collision and be key to fueling the binary AGN. Mrk 739E has a high Eddington ratio of 0.71 and a small black hole (log M_BH=7.05\pm0.3) consistent with an efficiently accreting AGN. Other than NGC 6240, this stands as the nearest case of a binary AGN discovered to date.

description: We present a multi-wavelength analysis of the properties of Extremely Red Galaxy (ERG) populations, selected in the GOODS-South/Chandra Deep Field South field. By using all the photometric and spectroscopic information available on large deep samples of EROs (645 sources), IEROs (294 sources), and DRGs (350 sources), we derive redshift distributions, identify AGN powered and Star-formation powered galaxies, and, using the radio observations of this field, estimate robust (AGN- and dust-unbiased) Star Formation Rate Densities (SFRD) for these populations. We also investigate the properties of "pure" (galaxies that conform to only one of the three ERG criteria considered) and "combined" (galaxies that verify all three criteria) sub-populations. Overall, a large number of AGN are identified (up to ~30%, based on X-rays, and mid-infrared criteria), the majority of which are type-2 (obscured) objects. Among ERGs with no evidence for AGN activity, we identify sub-populations covering a wide range of average star-formation rates, from below 10 Mo/yr to as high as 200 Mo/yr.

description: Efficient reaction monitoring is crucial for data acquisition in kinetic and mechanistic studies. However, for conversions of nucleosides to their corresponding nucleobases, as observed in enzymatically catalyzed nucleoside phosphorylation reactions, the current analytical arsenal does not meet modern requirements regarding cost, speed of analysis and high throughput. Herein, we present a UV/Vis spectroscopy-based assay employing an algorithm for spectral unmixing in a 96-well plate format. The algorithm relies on fitting of reference spectra of nucleosides and their bases to experimental spectra and allows determination of nucleoside/nucleobase ratios in solution with high precision. The experimental procedure includes appropriate dilution of a sample into aqueous alkaline solution, transfer to a multi-well plate, measurement of a UV/Vis spectrum and subsequent in silico spectral unmixing. This enables data collection in a high-throughput fashion and reduces costs compared to state-of-the-art HPLC analyses by approximately 5-fold while being 20-fold faster and offering comparable precision. Additionally, the method is robust regarding dilution and sample transfer errors as it only considers spectral form and not absolute intensity. It can be applied to all natural nucleosides and nucleobases and even unnatural ones as demonstrated by several examples.

description: Pyrimidine-nucleoside phosphorylases (Py-NPases) have a significant potential to contribute to the economic and ecological production of modified nucleosides. These can be produced via pentose-1-phosphates, an interesting but mostly labile and expensive precursor. Thus far, no dynamic model exists for the production process of pentose-1-phosphates, which involves the equilibrium state of the Py-NPase catalyzed reversible reaction. Previously developed enzymological models are based on the understanding of the structural principles of the enzyme and focus on the description of initial rates only. The model generation is further complicated, as Py-NPases accept two substrates which they convert to two products. To create a well-balanced model from accurate experimental data, we utilized an improved high-throughput spectroscopic assay to monitor reactions over the whole time course until equilibrium was reached. We examined the conversion of deoxythymidine and phosphate to deoxyribose-1-phosphate and thymine by a thermophilic Py-NPase from Geobacillus thermoglucosidasius. The developed process model described the reactant concentrations in excellent agreement with the experimental data. Our model is built from ordinary differential equations and structured in such a way that integration with other models is possible in the future. These could be the kinetics of other enzymes for enzymatic cascade reactions or reactor descriptions to generate integrated process models.

During several days we monitored the Larmor frequency of neutron spins in a weak magnetic field using the Ramsey resonance technique. An non-zero cosmic axial field, violating rotational symmetry, would induce a daily variation of the precession frequency. Our null result constitutes one of the most stringent tests of Lorentz invariance to date.

description: This paper provides a new geospatial perspective on whether or not Zipf's law holds for all cities or for the largest cities in the United States using a massive dataset and its computing. A major problem around this issue is how to define cities or city boundaries. Most of the investigations of Zipf's law rely on the demarcations of cities imposed by census data, e.g., metropolitan areas and census-designated places. These demarcations or definitions (of cities) are criticized for being subjective or even arbitrary. Alternative solutions to defining cities are suggested, but they still rely on census data for their definitions. In this paper we demarcate urban agglomerations by clustering street nodes (including intersections and ends), forming what we call natural cities. Based on the demarcation, we found that Zipf's law holds remarkably well for all the natural cities (over 2-4 million in total) across the United States. There is little sensitivity for the holding with respect to the clustering resolution used for demarcating the natural cities. This is a big contrast to urban areas, as defined in the census data, which do not hold stable for Zipf's law.

The Test-Retest Reliability and Familial Concordance of Individual Symptoms of Major Depressive Disorder

description: Major Depressive Disorder (MDD) is a heterogenous syndrome, which likely contributes to the diagnosis’s questionable test-test reliability (Regier et al., 2013). MDD consists of nine core symptoms, most of which are unaggregated (e.g., sleep disturbance includes hypersomnia or insomnia). Individual depression symptoms may therefore exhibit different psychometric properties. This study examined two psychometric properties of the individual symptoms of MDD: (1) test-retest reliability and (2) familialness (i.e., whether they run in families). These two psychometric properties were examined for (1) the categorical diagnosis of MDD, (2) aggregated symptoms, and (3) unaggregated symptoms. Lifetime depression symptoms were measured in 504 young adults (237 sibling pairs) using an adapted version of the Structured Clinical Interview for DSM-5 (SCID; Shankman et al., 2018). Fifty-one people completed a second SCID within three weeks of their first SCID (M = 8.5 days, SD = 4.31). The test-retest reliability and familialness of each lifetime MDD symptom was evaluated using Cohen’s Kappa and established conventions for agreement (Cohen, 1960). The lifetime diagnosis of MDD had substantial test-retest reliability (k = .68). The test-retest reliabilities for aggregated and unaggregated symptoms fell into the moderate to substantial range (k’s ranged .52-.72). The lifetime diagnosis of MDD had fair familial concordance (k = .21). The familial concordance for the aggregated symptoms were highest for anhedonia (k = .28) and depressed mood (k = .21). At the unaggregated symptom level, the symptoms that comprise anhedonia—loss of interest (k = .21) and loss of pleasure (k = .25)—had the highest familial concordance and were in the fair agreement range. Given the increasing focus on the differential validity of individual MDD symptoms, our findings help illuminate whether interview-based assessments of individual symptoms reach an adequate level of reliability and validity.

description: Measurements of inclusive W and Z boson production cross sections in pp collisions at sqrt(s)=7 TeV are presented, based on 2.9 inverse picobarns of data recorded by the CMS detector at the LHC. The measurements, performed in the electron and muon decay channels, are combined to give sigma(pp to WX) times B(W to muon or electron + neutrino) = 9.95 \pm 0.07(stat.) \pm 0.28(syst.) \pm 1.09(lumi.) nb and sigma(pp to ZX) times B(Z to oppositely charged muon or electron pairs) = 0.931 \pm 0.026(stat.) \pm 0.023(syst.) \pm 0.102(lumi.) nb. Theoretical predictions, calculated at the next-to-next-to-leading order in QCD using recent parton distribution functions, are in agreement with the measured cross sections. Ratios of cross sections, which incur an experimental systematic uncertainty of less than 4%, are also reported.

description: We propose to construct a family of states of one-dimensional spin chains by replacing the finite dimensional matrices in matrix product states by infinite dimensional operators constructed from bosonic annihilation and creation operators. The resulting states are demonstrated to violate the area law and to exhibit long range correlations. In addition, we propose an efficient way to prepare the states experimentally, in which the spins interact sequentially with an ancilla system.

Architectures of raciality : racial grids and the convergences of the racial nonhuman in Canada, Singapore, and Malaysia
Creators: name: O'Brien, Michelle Siobhan
Publisher: name: University of British Columbia
Year: 2016

description: This dissertation examines the emergence of racial grids, which define and organize categories of racial difference in relation to one another in a hierarchical manner, in Canada, Singapore, and Malaysia. It considers their varied approaches to embodied lived experiences of race and as belonging to a broader logic of raciality across the postcolonial world. This project focuses on three thematic points of comparison: the use of English as a mediator of racial distinction; the lasting influence of narratives of raciality that emerged during moments of inter-communal violence; and more recent recastings of these grids under forms of state-directed multiculturalism under conditions of globalization. This project examines these issues through sociopolitical theory and socio-juridical documents, as well as through Asian Canadian literature and post-Independence writing in English from Malaysia and Singapore. Drawing the work of Denise Ferreira da Silva, Frantz Fanon, Michel Foucault, and Jacques Derrida, this dissertation theorizes a figuration called the racial nonhuman in order to analyze how race organizes populations based on human types and defines them against an ideal, that is white and European, human. The racial nonhuman is engendered by historical, socio-juridical, and aesthetic discourses that render particular bodies as simultaneously within these nations and their demands for different racial types, but outside their ideal body politic. I analyze works by Fred Wah, Shirley Lim, Larissa Lai, Tan Twan Eng, and Lydia Kwa to compare how these nations have instituted and maintained their racial grids, as well as to examine how the racial nonhuman is contested and reimagined across these contexts.

description: A pressing problem for supersymmetry (SUSY) phenomenologists is how to incorporate Large Hadron Collider search results into parameter fits designed to measure or constrain the SUSY parameters. Owing to the computational expense of fully simulating lots of points in a generic SUSY space to aid the calculation of the likelihoods, the limits published by experimental collaborations are frequently interpreted in slices of reduced parameter spaces. For example, both ATLAS and CMS have presented results in the Constrained Minimal Supersymmetric Model (CMSSM) by fixing two of four parameters, and generating a coarse grid in the remaining two. We demonstrate that by generating a grid in the full space of the CMSSM, one can interpolate between the output of an LHC detector simulation using machine learning techniques, thus obtaining a superfast likelihood calculator for LHC-based SUSY parameter fits. We further investigate how much training data is required to obtain usable results, finding that approximately 2000 points are required in the CMSSM to get likelihood predictions to an accuracy of a few per cent. The techniques presented here provide a general approach for adding LHC event rate data to SUSY fitting algorithms, and can easily be used to explore other candidate physics models.

description: A generalized parity-time (PT)-symmetric telemetric sensing technique, which enables new mechanisms to manipulate radio frequency (RF) interrogation between the sensor and the reader, in order to boost the effective Q-factor and sensitivity of wireless microsensors was theoretically proposed and experimentally shown. This sensing technique which used MEMS-based wireless pressure sensors operating in the radio-frequency spectrum, overcame the long-standing challenge of implementing a miniature wireless microsensor with high spectral resolution and high sensitivity, and opened opportunities to develop loss-immune high-performance sensors, due to gain-loss interactions via inductive coupling and eigenfrequency bifurcation resulting from the PT (PTX)-symmetry. It was shown that a real and constant eigenfrequency in specific higher-order of the generalized PT-symmetric electronic systems was exploited to realize a robust wireless power transfer platform locked to the frequency of operation. This PT system, provided breakthrough in dynamic and alignment-free wireless charging technology with extended range wireless charging and sensing at the same time.
The Hidden Costs of Crime and Air Pollution

description: This dissertation focuses on the costs of air pollution and crime. In the first chapter, I address a gap in the literature concerning air pollution’s impacts on human capital formation. I investigate the impact of ambient fine particulate matter on children’s learning using policy-induced variation in air pollution. The North Carolina Clean Smokestacks Act of 2002 mandated emissions reductions from coal-fired power plants. This resulted in utility providers installing pollution mitigating technology on a fraction of the coal-fired power plants in the state. This policy reduced exposure to particulate matter throughout the state but had larger impacts for schools closest to power plants. Using this quasi-experimental variation and an Instrument Variable approach, I find that reduction in air pollution significantly increased academic gains for students in grades four through eight. A one microgram per cubic meter drop in particulate matter results in improvements of 4.8% and 4.0% of a standard deviation in math and reading respectively. The results indicate that air quality can significantly impact human capital. In the second chapter, I challenge past claims that avoidance behavior associated with crime imposes large costs on society. The previous literature, based on survey evidence, showed that individuals avoid public transportation due to crime. This can lead to welfare losses for public transportation riders and lost revenue for the transit authority. Using a Difference-in-Difference style identification strategy, I investigate the impact of violent crime at Chicago Transit Authority metro train stations on train ridership. Results indicate that crime does not impact ridership in the short-term, even in the most sensitive of groups such as students, seniors, and weekend riders. This evidence implies that the cost of avoidance behavior may not be as large as previously suspected. Future cost of crime estimates may not need to be adjusted for avoidance behavior costs.
