description: We followed a cohort of 223 intravenous drug users (99 HIV and 124 HIV+) for up to 3.5 years, examining change in performance over time as a function of HIV status, disease severity, and neurological signs and symptoms. Analyses were performed by applying generalized estimating equations (GEE) to regression analyses with repeated measures, and controlled for age, education, and length of substance use. None of the subjects had AIDS at baseline. There were 147 men (85 HIV+ and 62 HIV) and 76 women (39 HIV+ and 37 HIV). Memory performance was worse in the HIV+ than HIV− women. In the men, performance on the memory, executive, language, and attention factors improved significantly overtime, but this improvement was attenuated in the HIV men for the attention and orientation factors. In the HIV+ women. AIDS was associated with worsening performance on attention tests. The presence or onset of clinically significant neurological findings was associated with poorer language and motor speed performance. In the HIV+ men, memory performance was worse when the CD4 count fell below 200: it declined over time in men with AIDS but not in those without. A learning effect for language was attenuated in men who developed AIDS. The presence or development of a clinically significant neurological sign was associated with poorer memory, executive, language, attention, and motor speed performance. Our findings parallel those that we previously reported in a prospectively followed cohort of gay men. In combination, our studies of gay men and IDU cohorts suggest that (a) HIV can affect cognition early, even when the patient is medically asymptomatic; (b) cognitive difficulties worsen as the severity of HIV infection increases; and (c) the advent of clinically significant neurologic signs is associated with progression to more severe cognitive deficits. Our data suggest that the neurological and neuropsychological changes are both manifestations of the central effect of HIV on the CNS.

description: We describe the structure and dynamics of turbulence by the scale-dependent perceived velocity gradient tensor as supported by following four tracers, i.e. fluid particles, that initially form a regular tetrahedron. We report results from experiments in a von Kármán swirling water flow and from numerical simulations of the incompressible Navier-Stokes equation. We analyze the statistics and the dynamics of the perceived rate of strain tensor and vorticity for initially regular tetrahedron of size $r_0$ from the dissipative to the integral scale. Just as for the true velocity gradient, at any instant, the perceived vorticity is also preferentially aligned with the intermediate eigenvector of the perceived rate of strain. However, in the perceived rate of strain eigenframe fixed at a given time $t=0$, the perceived vorticity evolves in time such as to align with the strongest eigendirection at $t=0$. This also applies to the true velocity gradient. The experimental data at the higher Reynolds number suggests the existence of a self-similar regime in the inertial range. In particular, the dynamics of alignment of the perceived vorticity and strain can be rescaled by $t_0$, the turbulence time scale of the flow when the scale $r_0$ is in the inertial range. For smaller Reynolds numbers we found the dynamics to be scale dependent.

description: The use of technology to monitor patients outside of traditional healthcare settings such as hospitals or clinics, known as remote healthcare, is a fast-growing field. This approach has  become increasingly popular in recent years as the world moves towards continuous real-time health monitoring for early and swift detection of illnesses. Due to the rise in illness and mortality rates resulting from poor health worldwide, there is a growing demand for more healthcare facilities, making remote monitoring an ideal solution. Additionally, remote monitoring is a practical option for meeting healthcare needs within a reasonable timeframe and with available infrastructure.

One of the contributions of the thesis is to perform a comprehensive literature review on remote health/patient monitoring. It involves a systematic search and analysis of published studies, reports, and relevant literature to identify research trends, gaps, and challenges. It helps to understand the current state of research, highlight research questions and gaps, and suggest future research directions. Similarly, another contribution is to understand the need of infant and maternity remote health monitoring. It focuses on identifying additional challenges in the development and implementation of remote monitoring systems for pregnant women and infants. It provides insights into the current state of research, research questions and gaps, and future research directions in this area.

The main contribution of this research is to propose a system that remotely monitors a patient's health by maintaining up-to-date health records from both the patient and the doctor's side. The system is based on a smart connected health network or a patient-centric health network that covers basic personal information such as uploading personal profiles, health records, and medical reports.

Moreover, this system also addresses the main challenges faced by patients, such as tracking health records and maintaining them while traveling abroad, booking appointments, etc. To achieve this, the monitoring system employs both invasive or wearable sensor methods and non-invasive or contactless methods. This system also deals with interoperability issues that exist between existing systems to provide a more convenient experience for patients in managing their health records. The system is designed to be user-friendly, similar to social media platforms, providing an interactive layout that makes it easy and interesting for patients to use. 

Overall, the proposed system aims to improve the patient experience by providing an efficient and easy-to-use platform for remote patient monitoring and health record management. It has the potential to revolutionize the way healthcare is delivered and can provide patients with better outcomes and quality of life.

Alzheimer's disease--Forecasting

description: The presence of extrapyramidal signs or psychosis may indicate greater disability in patients with probable Alzheimer's disease. We evaluated the ability of these signs, noted at a patient's first visit, to predict one of two specific clinical endpoints: (1) a preselected score on the modified Mini-Mental State examination (cognitive endpoint), and (2) a preselected score on the Blessed Dementia Rating Scale (functional endpoint). Sixty-five patients were followed either until they reached the endpoints or to the end of the study period. Survivorship curves were drawn to predict the distribution of time to onset of an endpoint in patients with and without the clinical signs. Time to reach the cognitive endpoint was shorter for patients with extrapyramidal signs or psychosis compared with those without these signs and symptoms. These clinical signs did not predict the functional endpoint. We conclude that extrapyramidal signs and psychosis may be useful predictors of intellectual decline in Alzheimer's disease.

description: We analyze the quantum states of two atoms in a combined harmonic oscillator and periodic lattice trap in one spatial dimension. In the case of tight-binding and only nearest neighbor tunneling, the equations of motion are conveniently represented in the momentum representation. We show that in the case of strong attraction between the particles, the different time scales of relative and center-of-mass motion validate a separation of the problem similar to the Born-Oppenheimer approximation applied in the description of electronic and nuclear motion in molecules.

description: No abstracts are to be cited without prior reference to the author.The climate-driven extension of the range of the spiny sea urchin (Centrostephanus rodgersii) from Australia’s mainland into Tasmanian waters presents a major threat to the productivity of native subtidal rocky-reef communities. Overgrazing of native seaweed beds by this sea urchin can create and maintain extensive zones of barren habitat, causing major loss of production, biodiversity, and physical structure. In particular, the two most valuable fisheries in Tasmania, blacklip abalone (Haliotis rubra) and southern rock lobster (Jasus edwardsii), are not viable on C. rodgersii barrens. In addition, the fishing depletion of large rock lobsters, the main natural predator of C. rodgersii, facilitates the establishment of urchin barrens. Based on data from empirical observations and field experiments, we develop a generic ecological model of the local dynamics of Tasmanian reef communities. The model captures ecosystem shifts from productive kelp bed to sea urchin barren. Through simulations, we assess the effectiveness of alternative management options to control the ecological impacts of the invasive urchin species, either by maintaining native reef communities in their original state, or by restoring the productive seaweed habitat from an urchin barren state

description: We investigate the ${\cal O}(α_s)$ corrections to $e^+e^-\to J/ψ(ψ')+χ_{cJ}$ ($J=0,1,2$) in the NRQCD factorization approach. These next-to-leading order (NLO) corrections are calculated at the level of helicity amplitude. We have made a detailed analysis for both polarized and unpolarized cross sections, and compared our predictions with the measurements at the $B$ factories. We also derive the asymptotic expressions for each of the NLO helicity amplitudes, and confirm the earlier speculation that at NLO in $α_s$, the double logarithm of type $\ln^2 (s/m_c^2)$ appearing in the NRQCD short-distance coefficient is always associated with the helicity-suppressed channels.

description: We show that the modulated reheating mechanism can naturally account for dark radiation, whose existence is hinted by recent observations of the cosmic microwave background radiation and the primordial Helium abundance. In this mechanism, the inflaton decay rate depends on a light modulus which acquires almost scale-invariant quantum fluctuations during inflation. We find that the light modulus is generically produced by the inflaton decay and therefore a prime candidate for the dark radiation. Interestingly, an almost scale-invariant power spectrum predicted in the modulated reheating mechanism gives a better fit to the observation in the presence of the extra radiation. We discuss the production mechanism of the light modulus in detail taking account of its associated isocurvature fluctuations. We also consider a case where the modulus becomes the dominant component of dark matter.

description: No abstracts are to be cited without prior reference to the author.Based on the information on salinity and temperature needed for survival and reproduction, areas within the Baltic Sea have been identified where the American comb jelly (Mnemiopsis leidyi) could potentially survive and reproduce. In addition, physical drift modelling has been used to investigate the potential dispersion of Mnemiopsis, with the assumption that the invasion occurred via advection from the Kattegat through the Danish Straits into the western Baltic Sea. In the low saline surface layer, the dispersion is mainly driven by the wind; in the lower saline layer, the dispersion is controlled by the baroclinic flowfield and bottom topography. Model runs showed that natural spreading via deep-water currents from the Bornholm Basin where it currently occurs, towards north and east, is limited by topographic obstacles and low advection velocities. However, if Mnemiopsis were transported in the ballast water of a ship to the northern latitudes it might survive but would not reproduce at a sufficient rate to establish a new population. Thus, as a result of the combined effects of low salinity and low temperature it is not probable that Mnemiopsis could establish permanent populations in the central or northern Baltic Sea. It seems that Mnemiopsis could only reproduce at higher rate in the southern parts of the sea. If under climate change the salinity in the Baltic Sea further decreases, the establishment of Mnemiopsis would be even less probable in the north although water temperature would increase.
Evaluating emotional intelligence and resiliency outcomes of school-aged children in a social and emotional learning program

Publisher: name: University of British Columbia
Year: 2012

description: A school-based social emotional learning (SEL) program based on cognitive-behavioural principles is currently used in western Canadian schools; however, research on its benefits to child participants is limited. This controlled study reports on data collected from 152 grade three and four students; 70 students participated in the evidence-based program, FRIENDS for Life for Children (FRIENDS; Barrett, 2004) and 82 students were in the control group. All participants were assessed for emotional intelligence (EI) and resiliency at 3 time points: immediately before the start of the program (Time 1), immediately following the end of the program (Time 2), and at 3-months follow-up (Time 3). Resiliency is defined as an ability to deal effectively with difficulties or adversity and resist environmental risk experiences (Rutter, 2006). Assessments included two child-report measures (Strengths and Difficulties Questionnaire – Student Report; Emotional Quotient Inventory – Youth Version), two parent-report measures (Behavior Assessment System for Children – Parent Rating Scales; Social Competence Scale – Parent Version) and one teacher-report measure (Strengths and Difficulties Questionnaire – Teacher Report). Teachers in the intervention group also completed a FRIENDS fidelity checklist. Data were analyzed using between-groups independent samples t-tests and five separate within-group 2 x 3 MANOVAs. Results indicate that between-groups scores (FRIENDS vs. Control) did not statistically differ at any assessment period on any measure, but that within-group scores from children who participated in the program showed statistically significant increases on the Emotional Quotient Inventory – Youth Version Total EQ subscale (Time 1 vs. Time 2, and Time 1 vs. Time 3) and the Social Competence Scale – Parent Version Total Score (Time 1 vs. Time 3) over time. These increases suggest that children who participated in FRIENDS self-reported increased intrapersonal and interpersonal skills, adaptability, and stress management abilities over time, and that parents of children in FRIENDS reported increased social skills and emotion regulation abilities in their children over time. Teachers did not report observing differences in their students over time.

Using a field dependant map among gauge parameters we show that the symmetries obtained from this generator are on-shell equivalent to the Poincaré gauge symmetries. We also clarify certain subtle issues concerning the implementation of this map.

description: Electromagnetic interactions are discussed in the context of the Klein-Gordon fermion equation. The Mott scattering amplitude is derived in leading order perturbation theory and the result of the Dirac theory is reproduced except for an overall factor of sixteen. The discrepancy is not resolved as the study points into another direction. The vertex structures involved in the scattering calculations indicate the relevance of a modified Klein-Gordon equation, which takes into account the number of polarization states of the considered quantum field. In this equation the d'Alembertian is acting on quaternion-like plane waves, which can be generalized to representations of arbitrary spin. The method provides the same relation between mass and spin that has been found previously by Majorana, Gelfand, and Yaglom in infinite spin theories.

description: No abstracts are to be cited without prior reference to the author.European green crabs (Carcinus maenas) were introduced to Prince Edward Island, eastern Canada, just over a decade ago. Since then, preliminary observations suggest that the species continue to spread and grow I numbers that may become detrimental to a variety of shellfish resources. To document their potential spread and impact on oyster habitats, we carried out trapping surveys in several estuaries during 2008, 2009, and 2010, and conducted a series of predator–prey (crab-–oyster) manipulations. The trapping surveys confirmed that there is an ongoing spread of green crabs into new suitable areas, while rapidly increasing in numbers in most others. Aiming to facilitate potential mitigation strategies, we ran a series of field inclusions to identify both the size of oysters most vulnerable to green crab predation, and the crab sizes most detrimental to oysters. Specifically, we measured the predation rates of small, medium, and large green crabs feeding on small, medium, large, and extra large oysters. In general, almost no predation occurred on extra-large oysters, but large green crabs preyed more heavily on all other oyster sizes. As expected, small oysters were most vulnerable to predation by virtually every size of green crab. Overall, our results suggest that the outcomes of green crab–oyster predator–prey interactions are heavily dependent on both oyster size and crab size with oysters reaching a partial size refuge from green crabs at ~35 mm. We discuss these results in the light of the oyster industry and the further spread and growth of green crabs in the region.

description: A series of new substituted triazolo[4,5-d]pyrimidine derivatives linked to thienopyrimidine ring system were prepared as a hybrid heterocyclic systems, as possible nucleobases analogs, starting from the key carboxamide derivative 2 and its azide precursor via heterocyclization reactions and their structures were characterized. Glycosylation of the prepared triazolopyrimidine derivatives was performed and afforded, regioselctively, the corresponding thienopyrimidine-triazolopyrimidine hybrid N1-glycosides and their thioglycoside analogues in good yields. The synthesized glycosyl heterocycles were studied for their cytotoxic activity against HepG-2 and MCF-7 human cancer cells and significant results were obtained. Compounds 7a, 8 b, 9 b, 9a and 7 b demonstrated promising activities comparable to the activity of the doxorubicin for (HepG-2) cell line. Furthermore, a number of the afforded triazolopyrimidine glycosides were found potent against cancer cells (MCF-7). Furthermore, docking simulation the promising thienopyrimidine analogues 7-13 was done against EGFR kinase to provide a binding model that could serve in discovery of further anticancer agents.

description: We study contact terms of conserved currents and the energy-momentum tensor in three-dimensional quantum field theory. They are associated with Chern-Simons terms for background fields. While the integer parts of these contact terms are ambiguous, their fractional parts are meaningful physical observables. In N=2 supersymmetric theories with a U(1)_R symmetry some of these observables lead to an anomaly. Moreover, they can be computed exactly using localization, leading to new tests of dualities.

description: We show that the near-extremal solutions of Einstein-Maxwell-Dilaton theories, studied in ArXiv:1005.4690, provide IR quantum critical geometries, by embedding classes of them in higher-dimensional AdS and Lifshitz solutions. This explains the scaling of their thermodynamic functions and their IR transport coefficients, the nature of their spectra, the Gubser bound, and regulates their singularities. We propose that these are the most general quantum critical IR asymptotics at finite density of EMD theories.

description: No abstracts are to be cited without prior reference to the author.Biological invasions by alien species are recognized as an important component of global environmental change, often resulting in significant loss in the economic value, biological diversity, and function of invaded ecosystems. More than 1000 alien multicellular species have been recorded from European seas. Approximately 600 taxa have established self-sustaining populations, the great majority of them in the Mediterranean Sea. The dominating group of exotic species across all European seas is zoobenthos organisms. The most important introduction pathways for alien species are: canals (Mediterranean Sea), shipping, aquaculture, or stocking activities (Baltic Sea and Atlantic coast). Recently, a standardized method, the Biopollution Level (BPL) Index, was proposed to measure the magnitude of bioinvasion impacts. The estimated biopollution level is a combination of abundance and distribution range (ADR) class and the impact of alien species on communities (C), invaded habitat (H), and ecosystem functioning (E). For instance, the slipper limpet (Crepidula fornicata) in the North Sea and Atlantic coast occurs at densities of >1700 m–2, resulting in trophic competition and causing reduced growth of commercial bivalves; it also changes sediments to mud deposits, thus reducing diversity and abundance of living plants. Therefore the assigned biopollution level for the species is strong (BPL = 3). Following this approach, the bioinvasion impacts of the target alien species could be quantified.

description: We develop an analytic halo model for the distribution of dust around galaxies. The model results are compared with the observed surface dust density profile measured through reddening of background quasars in the Sloan Digital Sky Survey (SDSS) reported by Menard et al.(2010). We assume that the dust distribution around a galaxy is described by a simple power law, similarly to the mass distribution, but with a sharp cut-off at $αR_{\rm vir}$ where $R_{\rm vir}$ is the galaxy's virial radius and $α$ is a model parameter. Our model reproduces the observed dust distribution profile very well over a wide range of radial distance of $10 - 10^{4} h^{-1}$kpc. For the characteristic galaxy halo mass of $2\times 10^{12} h^{-1}M_{\odot}$ estimated for the SDSS galaxies, the best fit model is obtained if $α$ is greater than unity, which suggests that dust is distributed to over a few hundred kilo-parsecs from the galaxies. The observed large-scale dust distribution profile is reproduced if we assume the total amount of dust is equal to that estimated from the integrated stellar evolution over the cosmic time.

description: An identity by Chaundy and Bullard writes 1/(1-x)^n (n=1,2,...) as a sum of two truncated binomial series. In a paper which appeared in 2008 in Indag. Math. the authors surveyed many aspects of this identity. In the present paper we discuss much earlier occurrences of this identity in works by Hering (1868), de Moivre (1738) and de Montmort (1713). A relationship with Krawtchouk polynomials in work by Greville (1966) is also discussed.

description: Poly-γ-glutamic acid (γ-PGA) is an environment-friendly super absorbent polymer that can be used as a soil conditioner, which is promising to improve crop productivity and cope with soil degradation. The objectives of this study are to study the effects of γ-PGA on soil physicochemical properties and winter wheat (Triticum aestivum L. cv. Xinong 975) production in arid region of Northwest China. According to the mass ratio of γ-PGA and soil, experiment treatments consisted of four different γ-PGA application rates, which were designated as 0 (CK), 0.05% (P0.05), 0.1% (P0.1), and 0.15% (P0.15), respectively. The mixed soil samples were uniformly filled into identical plastic pots. Each treatment had three replicates randomly distributed within 12 pots. The results indicated that γ-PGA significantly increased saturated water content by 6.3-11.5%, field capacity by 8.4-15.3%, and plant available water by 5.1-12.5% compared with the CK. γ-PGA increased soil NO3−-N content and residue, and enhanced the proportions of soil macro-aggregates compared with the CK. γ-PGA increased winter wheat yield by 29.3-34.7%, and WUE by 21.2-33.3% compared with the CK. The main conclusion γ-PGA application amount of 0.05-0.1% can be used to improve soil physicochemical properties and winter wheat production in degraded soil.
Quantum deflagration and supersonic fronts of tunneling in molecular magnets

description: Theory of magnetic deflagration taking into account dipolar-controlled spin tunneling has been applied to the realistic model of molecular magnet Mn_12 Ac. At small transverse field, the front speed v has tunneling maxima on the bias field B_z reflecting those of the molecular spin's relaxation rate calculated from the density-matrix equation. At high transverse field, spin tunneling directly out of the metastable ground state leads to front speeds that can exceed the speed of sound. Both for the weak and strong transverse field, the spatial profile of the deflagration front near tunneling resonances shows a front of tunneling that triggers a burning front behind it.

description: Collaborative intervention practices involving family members have become a common tool for addressing social communication deficits in children with autism spectrum disorder (ASD). Sibling-mediated interventions represent an underutilized collaborative model despite the unique role of typically-developing siblings in the lives of children with ASD. Barriers to widespread utilization include logistical challenges for already-burdened families of children with ASD, as well as the need to protect siblings’ psychological well-being. The present study is a replication and extension of a previous sibling-mediated intervention study (Walton & Ingersoll, 2012) to determine whether using low-intensity, role-play-based training conducted in the absence of the child with ASD is an effective strategy to address these barriers. Three typically-developing siblings (ages 6-8) of children with ASD were recruited through a local ASD support group. Siblings successfully learned to use naturalistic developmental behavioral intervention strategies during role-play with an adult over the course of four one-hour, once weekly sessions. Play probes with their brother or sister with ASD (ages 5-10) suggest limited generalization of imitation and language modeling strategy use; however, siblings did not use the more complex imitation training procedure. Ratings by naïve observers supported the social validity of changes in play interactions. Participating siblings and parents rated participation in the program positively.
title: Ultrasonic tags reveal seasonal movements in red king crab (Paralithodes camtschaticus)

description: No abstracts are to be cited without prior reference to the author.The red king crab was introduced to the Barents Sea in the 1960s and has spread widely both in Norwegian and in Russian waters, entailing a need to acquire knowledge of the biology and behaviour of the crab in these areas. Twenty crabs of both sexes were tagged with ultrasonic coded acoustic transmitters and released at three sites in Porsangerfjord, Finnmark, Norway. Ten acoustic receivers were placed in a non-uniform grid in the experimental area, allowing us to track individual crabs for ca. 12 months. Results on seasonal movements according to depth and sex throughout the year are presented as well as long-term observations on individual crab behaviour. Daily movement speed of individual crabs is also calculated. Being a small introductory experiment, this study provides valuable information on the behaviour of a successful introduced species, essential knowledge for the understanding of the species and for pinpointing further investigations on the crab’s impact on the native ecosystem.
The challenges of constructing legitimacy in peacebuilding

description: Observing challenges in Afghanistan, Iraq, Sudan, Sierra Leone, the Democratic Republic of Congo, Haiti, Kosovo, East Timor, and Libya, to name a few, there is no doubt that peacebuilding—international efforts to create lasting peace in post-conflict states — is a critical issue in world politics. It appears to be a widely shared understanding among both scholars and policymakers that it is imperative for the peacebuilders—both international and domestic authorities in charge of creating peace—to obtain legitimacy in reconstructing war-torn states. Surprisingly, however, concrete methods or policies to construct legitimacy in “host states” have not been fully examined by either IR theorists or practitioners. The objective of this dissertation is to develop an understanding of the mechanism of constructing or eroding the legitimacy of newly created domestic governments in the specific context of peacebuilding. The existing accounts basically contend that constructing legitimate governments in post-conflict states largely depends on the level of force and level of resource distribution (or “guns and money”). On the contrary, my argument emphasizes that in addition to those two factors, other factors, such as inclusive governments reconciling with political adversaries and the substantial role of international organizations as a credible third party to establish the fairness and neutrality of the political process, are very critical in building the legitimacy of the domestic governments in the long run. In order to assess this argument, the dissertation conducts detailed process tracing to assess peacebuilding in Afghanistan as a primary case, demonstrating how the legitimacy of the Afghan government has been eroded. The dissertation also assesses the cases of Iraq, Sierra Leone and Timor-Leste (East Timor) in more concise fashion. All four cases support my argument about the requirements for an inclusive political process in peacebuilding as well as the important role of the UN which has often been dismissed by its critics. The research suggests important policy implications for peacebuilding and contributes to generating a theory that can be assessed by future studies.
The Šilov Boundary for Operator Spaces

description: Motivated by the recent interest in the examination of unital completely positive maps and their effects in C*-theory, we revisit an older result concerning the existence of the Šilov ideal. The direct proof of Hamana's theorem for the existence of an injective envelope for a unital operator subspace X of some B(H) that we provide implies that the Šilov ideal is the intersection of C*(X) with any maximal boundary operator subsystem in B(H). As an immediate consequence we deduce that the Šilov ideal is the biggest boundary operator subsystem for X in C*(X). The new proof of the existence of the Šilov ideal that we give does not use the existence of maximal dilations, provided by Dritschel and McCullough, and so it is independent of the one given by Arveson. As a countereffect, the Šilov ideal can be seen as the set that contains the abnormalities in a C*-cover (C,ι) of X for all the extensions of the identity map on ι(X). The interpretation of our results in terms of ucp maps characterizes the maximal boundary subsystems of X in B(H) as kernels of X-projections that induce completely minimal X-seminorms; equivalently, X-minimal projections with range being an injective envelope, that we view from now on as the Šilov boundary for X.
