Externalizing Problems

description: Prenatal drug exposure places infants and children at risk for numerous physical, cognitive, and behavioral problems, especially inattention/hyperactivity and externalizing problems. Extant prenatal drug exposure research has rarely studied the effects of exposure beyond the age of 12 and has failed to adjust for other important factors such as exposure to confounding variables like legal substances and the caregiving environment. In Study 1, the purpose was to understand whether or not there are differences by prenatal drug exposure status in middle childhood and early adolescence on key behavioral problems such as externalizing problems, attention problems, hyperactivity, violence behaviors, and risk propensity. No significant differences were found by prenatal drug exposure status on any behavior problems. In Study 2, the purpose was to examine early risk factors in infancy and potential middle childhood moderators that might explain early adolescent behavior problems. A poor caregiving environment in middle childhood predicted higher externalizing problems and violence behaviors in early adolescence. Additionally, high neighborhood violence and high informal family support in middle childhood predicted the highest levels of problem behaviors in early adolescence, and high neighborhood violence and low informal family social support predicted the lowest levels of problem behaviors. This same pattern was found with formal social support and problem behaviors as well as with formal social support and violence behaviors. Overall the findings support Blechman et al. (1995) and Moffitt's (1993) theories that the early environment does predict early adolescent behavior problems. A new study is proposed to collect better prenatal drug exposure data and to determine long-term outcomes for prenatally drug exposed children.

Habitat variation due to seasonal flooding of the lower Fraser river and the influence on the macroinvertebrate community
Creators: name: Rempel, Laura L.
Publisher: name: University of British Columbia
Year: 2009

description: Most large rivers of the world are of exceptional importance to many human uses but the ecosystems they support are often neglected in ecological research. The Fraser River, British Columbia, is a large river characterized by a regularly recurring flood cycle driven by snowmelt which seasonally inundates an extensive lateral shore zone. This study investigated the importance of the shore zone as a flow refugium to the macroinvertebrate community of the lower Fraser River during flooding, and the physical variations to the benthic habitat associated with flooding. Measures of hydraulic forces and substrate mobility were significantly higher at water depths of 1.5 and 3.0 m in the active channel during flooding of the Fraser River in 1995, than depths of 0.2 and 0.5 m within the shore zone where the substrate remained immobile. This variation produced a lateral gradient of increasing hydraulic stress from shallow to deep water depths along which the benthic community of the Fraser River appeared to be organized. The spatial distribution of invertebrate taxa generally reflected an organism's morphological and trophic suitability to particular hydraulic conditions which varied laterally between the shore zone and active channel. Shallow water depths of the shore zone satisfied the physical criteria of flow refugia by maintaining substrate stability and low hydraulic stress during flooding. Demonstrating the provision of flow refugia in the shore zone was the first of two steps to determining the ecological importance of the lateral shore zone for the persistence of the macroinvertebrate community during flooding in the Fraser River. The extent to which organisms used the shore zone during high flows was also necessary to confirm its refuge potential. On the rising limb of the flood hydrograph, total density and species richness remained stable while the wetted area of the channel increased significantly. The persistence of the invertebrate community appears to have been facilitated by a shift in the distribution of a major proportion of organisms from depths of 1.5 and 3.0 m in the active channel to the lateral shore zone during months of peak discharge. The ecological importance of this zone was demonstrated by the broad diversity of taxa with varying feeding behaviours and morphologies which concentrated in the shore zone.

description: We study the symmetry resolved entanglement entropies in one-dimensional systems with boundaries. We provide some general results for conformal invariant theories and then move to a semi-infinite chain of free fermions. We consider both an interval starting from the boundary and away from it. We derive exact formulas for the charged and symmetry resolved entropies based on theorems and conjectures about the spectra of Toeplitz+Hankel matrices. En route to characterise the interval away from the boundary, we prove a general relation between the eigenvalues of Toeplitz+Hankel matrices and block Toeplitz ones. An important aspect is that the saddle-point approximation from charged to symmetry resolved entropies introduces algebraic corrections to the scaling that are much more severe than in systems without boundaries.

description: The Via Lactea simulation of the dark matter halo of the Milky Way predicts the existence of many thousands of bound subhalos distributed approximately with equal mass per decade of mass. Here we show that: a) a similar steeply rising subhalo mass function is also present at redshift 0.5 in an elliptical-sized halo simulated with comparable resolution in a different cosmology. Compared to Via Lactea, this run produces nearly a factor of two more subhalos with large circular velocities; b) the fraction of Via Lactea mass brought in by subhalos that have a surviving bound remnant today with present-day peak circular velocity Vmax>2 km/s (>10 km/s) is 45% (30%); c) because of tidal mass loss, the number of subhalos surviving today that reached a peak circular velocity of >10 km/s throughout their lifetime exceeds half a thousand, five times larger than their present-day abundance and more than twenty times larger than the number of known satellites of the Milky Way; e) unless the circular velocity profiles of Galactic satellites peak at values significantly higher that expected from the stellar line-of-sight velocity dispersion, only about one in five subhalos with Vmax>20 km/s today must be housing a luminous dwarf; f) small dark matter clumps appear to be relatively inefficient at forming stars even well beyond the virial radius; g) the observed Milky Way satellites appear to follow the overall dark matter distribution of Via Lactea, while the largest simulated subhalos today are found preferentially at larger radii; h) subhalos have central densities that increase with Vmax and reach 0.1-0.3 Msun/pc3 comparable to the central densities inferred in dwarf spheroidals with core radii >250 pc.

description: Aspergilli represent an extremely important genus of microorganisms which can be both harmful pathogens, and beneficial pharmaceutical producers. In Aspergilli's interactions with man, suboptimal nutrient conditions are often present, and lead to a phenomenon known as autophagy. Autophagy is a cellular recycling mechanism that (in the case of macroautophagy) is augmented under nutrient-limited conditions to recycle cytoplasmic macromolecules and organelles for use in essential cell functions. Strategic manipulation of autophagy could ultimately lead to improved bioprocesses or anti-fungal treatments. Using the model filamentous fungus Aspergillus nidulans, a number of important questions about autophagy have been addressed.  Critical to the study of autophagy is the balance between self-degradation and self-preservation. Therefore, we adapted an XTT metabolic activity assay for use in filamentous fungi. The assay was first tested using a number of bioprocess-related stresses (e.g. temperature, shear), and found to be superior to DCW as an assessment of culture health. Next, the metabolic activity of fungal cultures was tested during autophagy-inducing conditions, demonstrating that the autophagy capable TN02A3 strain was more viable than an autophagy deficient ΔAnatg13 strain in nutrient limiting conditions.  By analyzing the proteome of key autophagy mutants ΔAnatg13 and ΔAnatg8, an improved molecular understanding of autophagy in filamentous fungi was achieved. Using 2-dimensional electrophoresis, 44 unique proteins were found with significant expression changes caused either by addition of rapamycin (a chemical inducer of autophagy) or deletion of Anatg13.  AnAtg13 dependent changes of multiple ribosomal and a key polyamine biosynthetic protein, spermidine synthase (AnSpdA), provides molecular evidence of AnAtg13 dependent lifespan extension in A. nidulans.  After establishing improved shotgun proteomic methods on the Thermo LTQ-XL, we generated a more thorough assessment of the A. nidulans response to autophagy by measuring protein expression as a function of time. It was found that autophagy induction caused a rapid and sustained increase in proteolysis, amino acid degradation, and lipid metabolism. Additionally, many proteins demonstrated a delayed change in expression. These included proteins involved in secretion, hydrolysis of alternative carbon sources, and secondary metabolite production; all of which are important to the bioprocess industry.

description: Oxygen vacancies play a crucial role in the control of the electronic, magnetic, ionic, and transport properties of functional oxide perovskites. Rare earth nickelates (RENiO$_{3-x}$) have emerged over the years as a rich platform to study the interplay between the lattice, the electronic structure, and ordered magnetism. In this study, we investigate the evolution of the electronic and magnetic structure in thin films of RENiO$_{3-x}$, using a combination of X-ray absorption spectroscopy and imaging, resonant X-ray scattering, and extended multiplet ligand field theory modeling. We find that oxygen vacancies modify the electronic configuration within the Ni-O orbital manifolds, leading to a dramatic evolution of long-range electronic transport pathways despite the absence of nanoscale phase separation. Remarkably, magnetism is robust to substantial levels of carrier doping, and only a moderate weakening of the $(1/4, 1/4, 1/4)_{pc}$ antiferromagnetic order parameter is observed, whereas the magnetic transition temperature is largely unchanged. Only at a certain point long-range magnetism is abruptly erased without an accompanying structural transition. We propose the progressive disruption of the 3D magnetic superexchange pathways upon introduction of point defects as the mechanism behind the sudden collapse of magnetic order in oxygen-deficient nickelates. Our work demonstrates that, unlike most other oxides, ordered magnetism in RENiO$_{3-x}$ is mostly insensitive to carrier doping. The sudden collapse of ordered magnetism upon oxygen removal may provide a new mechanism for solid-state magneto-ionic switching and new applications in antiferromagnetic spintronics.

description: We compute the c/a lattice strain versus temperature for nonmagnetic hcp iron at high pressures using both first-principles linear response quasiharmonic calculations based on the full potential linear-muffin-tin-orbital (LMTO) method and the particle-in-cell (PIC) model for the vibrational partition function using a tight-binding total-energy method. The tight-binding model shows excellent agreement with the all-electron LMTO method. When hcp structure is stable, the calculated geometric mean frequency and Helmholtz free energy of hcp Fe from PIC and linear response lattice dynamics agree very well, as does the axial ratio as a function of temperature and pressure. On-site anharmonicity proves to be small up to the melting temperature, and PIC gives a good estimate of its sign and magnitude. At low pressures, hcp Fe becomes dynamically unstable at large c/a ratios, and the PIC model might fail where the structure approaches lattice instability. The PIC approximation describes well the vibrational behavior away from the instability, and thus is a reasonable approach to compute high temperature properties of materials. Our results show significant differences from earlier PIC studies, which gave much larger axial ratio increases with increasing temperature, or reported large differences between PIC and lattice dynamics results.

description: Prompted by recent results on Susy-U(N)-invariant quantum mechanics in the large N limit by Veneziano and Wosiek, we have examined the planar spectrum in the full Hilbert space of U(N)-invariant states built on the Fock vacuum by applying any U(N)-invariant combinations of creation-operators. We present results about 1) the supersymmetric model in the bosonic sector, 2) the standard quartic Hamiltonian. This latter is useful to check our techniques against the exact result of Brezin et al. The SuSy case is where Fock space methods prove to be the most efficient: it turns out that the problem is separable and the exact planar spectrum can be expressed in terms of the single-trace spectrum. In the case of the anharmonic oscillator, on the other hand, the Fock space analysis is quite cumbersome due to the presence of large off-diagonal O(N) terms coupling subspaces with different number of traces; these terms should be absorbed before taking the planar limit and recovering the known planar spectrum. We give analytical and numerical evidence that good qualitative information on the spectrum can be obtained this way.

Predictors of Treatment Dropout in a Spiritually-based Therapeutic Community

Publisher: name: Maryland Shared Open Access Repository

Subjects: Psychology, Clinical (0622)

description: Survival analysis was used to determine the predictors of dropout from a spiritually-based therapeutic community (TC) for individuals with significant substance use problems. Participants' background characteristics, motivational readiness to change, religiosity, and psychological sense of community (PSOC) at treatment entry were tested to determine whether these variables were associated with early dropout.  Individuals who had a moderate level of motivational readiness at entry were less likely to dropout of the program than those with a low or high level of motivational readiness.  Individuals who reported a greater religiosity and PSOC within the TC were also significantly less likely to dropout than those who reported a low religiosity and PSOC.  However, changes in motivational readiness, religiosity, and PSOC during the early stages of the TC program (from treatment entry to 45 days into treatment) were not associated with duration of stay.  These findings suggest the importance of baseline characteristics in predicting one's likelihood to stay in a spiritually-based TC.  To decrease the rate of early dropout, it may be important to place greater emphasis on promoting one's PSOC early in the program.  Moreover, further work needs to address various aspects of religiosity and motivational readiness to change during the first week of program entry.
Novel proteomic tools to understand fungal cell wall development and repair

description: Filamentous fungi of genus Aspergillus represent a good assortment of microbes having enormous value in the bioprocessing industry and those demonstrating pathogenic activity in either plants [3] or people [4].  Fungal cell wall proteins (CWPs) protect the cell against stressful conditions in a fermenter [1], control branching [2,3] and are promising antifungal drug targets [4]. To this end the broad goal of my research is to develop novel proteomic strategies to identify and quantify change in expression of proteins that play a formidable role in cell wall development and repair.      To begin with we developed a procedure to extract cell wall proteins from isolated cell walls and identify them using shotgun proteomic workflows consisting of reverse phase liquid chromatography followed by tandem mass spectrometry (LC-MS/MS). In order to isolate cell walls we used sophisticated washing steps followed by two different approaches to extract CWPs from isolated cell walls which were then subjected to shotgun proteomics. Overall 34 nominal cell wall proteins were identified including proteins essential for cell wall integrity signaling (CWIS) and each step of cell wall biosynthesis.     Next we established a tool to quantify changes in cell wall protein expression compatible with shotgun proteomic workflow using Deuterium Isobaric Amine Reactive Tag (DiART) reagents. DiART represents cost-effective isobaric tagging reagents due to incorporation of deuterium isotopes. We corroborated the feasibility of performing protein quantitation on a LTQ mass spectrometer using quantitative data obtained from DiART tagged synthetic peptides, model protein mixtures and complex cell wall proteins. Subsequently we proved the applicability of DiART for quantitative phosphoproteomic workflows using DiART tagged phosphopeptides subjected to affinity enrichment using TiO2 resins.     Finally we focused our efforts on characterization of phosphorylation mediated regulatory networks in A. nidulans which would be valuable for overall fungal research. Using a bottom-up phosphoproteomic workflow and a state-of-the-art mass spectrometer Q-Exactive, we identified 1637 unique phosphopeptides from 647 phosphoproteins. Functional classification and kinase-substrate analysis collectively revealed clear association of the phosphoproteome and cellular events essential for fungal morphology and secretion.           Overall our methodology could be used to quantify changes in cell wall protein expression and phosphorylation, both of which are inherently observed in CWIS.

description: Observations in space plasmas reveal particle velocity distributions out of thermal equilibrium, with anisotropies (e.g., parallel drifts or/and different temperatures, $T_\parallel$ - parallel and $T_\perp$ - perpendicular, with respect to the background magnetic field), and multiple quasithermal and suprathermal populations with different properties. The recently introduced (isotropic) $κ$-cookbook is generalized in the present paper to cover all these cases of anisotropic and multi-component distributions reported by the observations. We derive general analytical expressions for the velocity moments and show that the common (bi-)Maxwellian and (bi-)$κ-$distributions are obtained as limiting cases of the generalized anisotropic $κ$-cookbook (or recipes). Based on this generalization, a new 2D fitting procedure is introduced, with an improved level of confidence compared to the 1D fitting methods widely used to quantify the main properties of the observed distributions. The nonlinear least-squares fit is \led{applied to electron data sets} measured by the Ulysses spacecraft confirming the existence of three different populations, a quasithermal core and two suprathermal (halo and strahl) components. In general, the best overall fit is given by the sum of a Maxwellian and two generalized $κ$-distributions.

description: We investigate the origin of the $\mathrm{Br}γ$ emission of the Herbig Ae star HD104237 on Astronomical Unit (AU) scales. Using AMBER/VLTI at a spectral resolution R=1500 spatially resolve the emission in both the BrGamma line and the adjacent continuum. The visibility does not vary between the continuum and the BrGamma line, even though the line is strongly detected in the spectrum, with a peak intensity 35% above the continuum. This demonstrates that the line and continuum emission have similar size scales. We assume that the K-band continuum excess originates in a ``puffed-up'' inner rim of the circumstellar disk, and discuss the likely origin of BrGamma. We conclude that this emission most likely arises from a compact disk wind, launched from a region 0.2-0.5 AU from the star, with a spatial extent similar to that of the near infrared continuum emission region, i.e, very close to the inner rim location.

description: The principle of Photo Response Non Uniformity (PRNU) is often exploited to deduce the identity of the smartphone device whose camera or sensor was used to acquire a certain image. In this work, we design an algorithm that perturbs a face image acquired using a smartphone camera such that (a) sensor-specific details pertaining to the smartphone camera are suppressed (sensor anonymization); (b) the sensor pattern of a different device is incorporated (sensor spoofing); and (c) biometric matching using the perturbed image is not affected (biometric utility). We employ a simple approach utilizing Discrete Cosine Transform to achieve the aforementioned objectives. Experiments conducted on the MICHE-I and OULU-NPU datasets, which contain periocular and facial data acquired using 12 smartphone cameras, demonstrate the efficacy of the proposed de-identification algorithm on three different PRNU-based sensor identification schemes. This work has application in sensor forensics and personal privacy.

description: On a lattice, we construct an overlap Dirac operator which describes the propagation of a Dirac fermion in external gravity. The local Lorentz symmetry is manifestly realized as a lattice gauge symmetry, while the general coordinate invariance is expected to be restored only in the continuum limit. The lattice index density in the presence of a gravitational field is calculated.

description: We live in a time marked by ecological precarity and crisis. Critical scholars of the Anthropocene have identified extractivism and its associated ideology of human exceptionalism as driving forces behind these crises. This thesis joins a call to develop naturalcultural theory – ways of conceptualizing the more-than-human world and our place in it as humans that do not rely on longstanding distinctions between “Nature” and “Culture.” Moreover, scholars and activists have clearly outlined the urgent need for us to change the way we live with nonhumans. As a step towards such new ways of living with nonhumans, in this project I study how foragers foster multispecies ethics through their encounters with nonhumans, using multispecies ethnography as my primary methodology. In this thesis, I develop a theoretical framework through which to understand forager-plant interactions, informed by my experiences in the field interviewing and observing foragers as they harvest plants and directly studying the plants that my participants frequently interacted with. I tentatively propose a distinction between extractive and non-extractive approaches to foraging. Overall, I suggest viewing plants and humans as living-persons who are tangled in a field of socioecological relations to one another. Through partial and intermittent encounters, they become contaminated and adopt new habits that affect their future interactions with other living-persons. This has important implications for how we conceive of ethics as only incorporating nonhumans as objects of ethical consideration rather than ethical subjects in their own right.
Quasi Periodic Oscillations and Strongly Comptonized X-ray emission from Holmberg IX X-1

description: We report the discovery of a 200mHz quasi-periodic oscillation (QPO) in the X-ray emission from a bright ultra-luminous X-ray source (ULX) Holmberg IX X-1 using a long XMM-Newton observation. The QPO has a centroid at 202.5_{-3.8}^{+4.9}mHz, a coherence Q ~9.3 and an amplitude (rms) of 6% in the 0.2-10keV band. This is only the second detection of a QPO from an ULX, after M82 X-1, and provides strong evidence against beaming. The power spectrum is well fitted by a power law with an index of ~0.7. The total integrated power (rms) is ~9.4% in the 0.001-1Hz range. The X-ray spectrum shows clear evidence for a soft X-ray excess component that is well described by a multicolor disk blackbody (kT_in ~ 0.3keV) and a high energy curvature that can be modeled either by a cut-off power law (Gamma ~ 1; E_cutoff ~9keV) or as a strongly Comptonized continuum in an optically thick (tau ~7.3) and cool (kT_e ~3keV) plasma. Both the presence of the QPO and the shape of the X-ray spectrum strongly suggest that the ULX is not in the high/soft or thermally dominated state. A truncated disk and inner optically thick corona may explain the observed X-ray spectrum and the presence of the QPO.

description: Making devices with graphene necessarily involves making contacts with metals. We use density functional theory to study how graphene is doped by adsorption on metal substrates and find that weak bonding on Al, Ag, Cu, Au and Pt, while preserving its unique electronic structure, can still shift the Fermi level with respect to the conical point by $\sim 0.5$ eV. At equilibrium separations, the crossover from $p$-type to $n$-type doping occurs for a metal work function of $\sim 5.4$ eV, a value much larger than the graphene work function of 4.5 eV. The numerical results for the Fermi level shift in graphene are described very well by a simple analytical model which characterizes the metal solely in terms of its work function, greatly extending their applicability.

Correlation functions of twist operators applied to single self-avoiding loops

description: The O(n) spin model in two dimensions may equivalently be formulated as a loop model, and then mapped to a height model which is conjectured to flow under the renormalization group to a conformal field theory (CFT). At the critical point, the order n terms in the partition function and correlation functions describe single self-avoiding loops. We investigate the ensemble of these self-avoiding loops using twist operators, which count loops which wind non-trivially around them with a factor -1. These turn out to have level two null states and hence their correlators satisfy a set of partial differential equations. We show that partly-connected parts of the four point function count the expected number of loops which separate one pair of points from the other pair, and find an explicit expression for this. We argue that the differential equation satisfied by these expectation values should have an interpretation in terms of a stochastic(Schramm)-Loewner evolution (SLE_kappa) process with kappa=6. The two point function in a simply connected domain satisfies a closely related set of equations. We solve these and hence calculate the expected number of single loops which separate both points from the boundary.

WOCS 5379: Detailed Analysis of the Evolution of a Post-Mass-Transfer Blue Straggler

description: The blue-straggler binary WOCS 5379 is a member of the old (6-7 Gyr) open cluster NGC 188. WOCS 5379 comprises a blue straggler star with a white dwarf companion in a 120-day eccentric orbit. Combined with the orbital period, this helium white dwarf is evidence of previous mass transfer by a red giant. Detailed models of the system evolution from a progenitor main-sequence binary, including mass transfer, are made using the Modules for Experiments in Stellar Astrophysics (MESA). Both of the progenitor stars are evolved in the simulation. WOCS 5379 is well reproduced with a primary star of initial mass 1.19 $M_{\odot}$, whose core becomes the white dwarf. The secondary star initially is 1.01 $M_{\odot}$. 300 Myr ago, the secondary finished receiving mass from the donor, having moved beyond the NGC 188 turnoff as a 1.20 $M_{\odot}$ blue straggler. The successful model has a mass transfer efficiency of 22\%. This non-conservative mass transfer is key to expanding the orbit fast enough to permit stable mass transfer. Even so, the mass transfer begins with a short unstable phase, during which half of the accreted mass is transferred. With increasing mass, the secondary evolves from a radiative core to a convective core. The final blue straggler interior is remarkably similar to a 2.1 Gyr-old 1.21 $M_{\odot}$ main-sequence star at the same location in the HR diagram. The white dwarf effective temperature is also reproduced, but the modeled white dwarf mass of 0.33 $M_{\odot}$ is smaller than the measured mass of 0.42 $M_{\odot}$.

Probing Universality in the Gravity Duals of N=1 SYM by gamma-deformations

description: Recently, a one-parameter deformation of the Maldacena-Nunez dual of the N=1 SYM theory was constructed in hep-th/0505100. According to the Lunin-Maldacena conjecture, the background is dual to pure N=1 SYM in the IR coupled to a KK sector whose dynamics is altered by a dipole deformation that is proportional to the deformation parameter gamma. Thus, the deformation serves to identify the aspects of the gravity backgrounds that bear the effects of the KK sector, hence non-universal in the dual gauge theory. We make this idea concrete by studying a Penrose limit of the deformed MN theory. We obtain an exactly solvable pp-wave that is conjectured to describe the IR dynamics of KK-hadrons in the field theory. The spectrum, the thermal partition function and the Hagedorn temperature are calculated. The Hagedorn temperature turns out to be independent of the deformation parameter.
