description: Dispersive liquid-liquid microextraction (DLLME) is a useful preconcentration technique but its direct application is limited to aqueous samples. Two pretreatment methods for solid samples, QuEChERS (quick easy cheap efficient rugged and safe) and a standard method, were used to isolate four polycyclic aromatic hydrocarbons (PAHs) from the sample matrix. However, since these methods result in analyte dilution, DLLME was used to augment them by concentrating the analytes from 8.0 mL of sample into 150 µL of 1,2-dichloroethane. Under the optimum conditions, the instrumental detection limit was enhanced by approximately 100-fold for chrysene, benzo[a]pyrene, benz[a]anthracene, and benzo[k]fluoranthene with corresponding detection limits of 29, 29, 30, and 28 ng/L, respectively. The precision of the method based on inter-analyst and inter-day analysis yielded relative standard deviations less than 9.0 and 4.0%, respectively. The optimized method was applied to snail samples spiked at 5.0, 10, 20, and 50 ng/g and the recoveries were nearly 100%. Matrix matched standards were also used to determine the recoveries; the results did not vary significantly from the direct calibration recoveries.
The maturation of the acoustic change complex in response to iterated ripple noise in normal-hearing toddlers

description: With the introduction of newborn hearing screening and early intervention programs, there has been an increase in the number of early-identified hearing loss. However, clinical audiological test batteries do not currently include an objective (i.e., not requiring responses from the patient) measure of speech discrimination in very young infants and difficult-to-test populations. The ability to process temporal speech cues to discriminate between speech sounds is disrupted in all degrees of sensorineural hearing loss and in populations with auditory neuropathy spectrum disorder. The purpose of this study was to investigate the maturational time course of a cortical auditory evoked potential, the acoustic change complex (ACC) elicited to iterated ripple noise (IRN), as a possible clinical measure of speech perception capacity. Previously, Small et al. (in prep) determined that ACC responses to IRN stimuli are not mature in infants up to 16 months old. Participants were 27 children divided into two groups: 13 younger children (22 to 32 months; 6 males) and 14 older children (38 to 59 months; 5 males). IRN stimuli were created with varying degrees of pitch saliency by adjusting the number of iterations (4, 8, 16 & 32); each 500-ms IRN stimulus was concatenated to a 500-ms noise stimulus to generate noise-IRN (experimental) and noise-noise (control) conditions. Onset and ACC responses were recorded to all conditions presented binaurally under insert earphones while children were awake. All children had responses present to every IRN condition for at least one electrode site. Latencies decreased significantly as the number of iterations increased and the older children had significantly shorter ACC latencies than the younger group. Amplitudes were significantly smaller for the younger children compared to the older children; however, the effect of condition on ACC amplitudes between age groups did not reach significance. Children as young as 22 months old have ACC responses elicited to low-saliency pitch stimuli, indicating that IRN discrimination abilities are emerging in this age group. Future research will determine how these processing abilities correlate with functional speech abilities in children with normal hearing and hearing loss.
The orbifold-string theories of permutation-type: II. Cycle dynamics and target space-time dimensions

description: We continue our discussion of the general bosonic prototype of the new orbifold-string theories of permutation type. Supplementing the extended physical-state conditions of the previous paper, we construct here the extended Virasoro generators with cycle central charge $\hat{c}_j(σ)=26f_j(σ)$, where $f_j(σ)$ is the length of cycle $j$ in twisted sector $σ$. We also find an equivalent, reduced formulation of each physical-state problem at reduced cycle central charge $c_j(σ)=26$. These tools are used to begin the study of the target space-time dimension $\hat{D}_j(σ)$ of cycle $j$ in sector $σ$, which is naturally defined as the number of zero modes (momenta) of each cycle. The general model-dependent formulae derived here will be used extensively in succeeding papers, but are evaluated in this paper only for the simplest case of the "pure" permutation orbifolds.

description: The purpose of this review is to compare and highlight the clinical and pathological aspects of genetic versus acquired Alzheimer’s disease: Down syndrome-associated Alzheimer’s disease in (DSAD) and Autosomal Dominant Alzheimer’s disease (ADAD) are compared with the late-onset form of the disease (LOAD). DSAD and ADAD present in a younger population and are more likely to manifest with non-amnestic (such as dysexecutive function features) in the prodromal phase or neurological features (such as seizures and paralysis) especially in ADAD. The very large variety of mutations associated with ADAD explains the wider range of phenotypes. In the LOAD, age-associated comorbidities explain many of the phenotypic differences.

description: Arbutin is used in cosmetics as a whitening ingredient. However, due to its potential to form the irritant hydroquinone upon degradation, its concentration in formulations has been restricted. In this study, a rapid, sensitive, and inexpensive method was established for the quantification of arbutin in cosmetic products. The innovation of this work is to use sodium hypochlorite to oxidize the arbutin phenolic group for rapid and specific determination. Excitation and emission wavelengths of 285 nm and 317 nm were employed. The solvent, pH, reaction time, and NaClO:arbutin ratio were optimized. The fluorescence intensity varied linearly with the arbutin concentration from 0.4 to 44 µg mL−1 with a detection limit of 0.1 µg mL−1. The validity of the method was characterized by the spike and recovery measurements; the recovery was from 96 to 106%. The method was employed for the analysis of marketed cosmetis containing arbutin.

description: We report a measurement of the mass of the top quark in lepton+jets final states of ppbar->ttbar data corresponding to 2.6 fb^{-1} of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider. Using a matrix element method, we combine an insitu jet energy calibration with our standard jet energy scale derived in studies of γ+jet and dijet events and employ a novel flavor-dependent jet response correction to measure a top-quark mass of mt = 176.01 +/- 1.64 GeV. Combining this result with our previous result obtained on an independent data set, we measure a top-quark mass of mt = 174.94 +/- 1.49 GeV for a total integrated luminosity of 3.6 fb^{-1}.

description: Individual induced pluripotent stem cells (iPSCs) show considerable phenotypic heterogeneity, but the reasons for this are not fully understood. Comprehensively analysing the mitochondrial genome (mtDNA) in 146 iPSC and fibroblast lines from 151 donors, we show that most age-related fibroblast mtDNA mutations are lost during reprogramming. However, iPSC-specific mutations are seen in 76.6% (108/141) of iPSC lines at a mutation rate of 8.62 × 10-5/base pair. The mutations observed in iPSC lines affect a higher proportion of mtDNA molecules, favouring non-synonymous protein-coding and tRNA variants, including known disease-causing mutations. Analysing 11,538 single cells shows stable heteroplasmy in sub-clones derived from the original donor during differentiation, with mtDNA variants influencing the expression of key genes involved in mitochondrial metabolism and epidermal cell differentiation. Thus, the dynamic mtDNA landscape contributes to the heterogeneity of human iPSCs and should be considered when using reprogrammed cells experimentally or as a therapy.
Measurement of mind wandering in natural and unnatural settings
Creators: name: Varao-Sousa, Patricia
Publisher: name: University of British Columbia
Year: 2019

description: Mind wandering (MW) is defined as a lapse of attention where one’s thoughts are focused inward, thus drawing attention away from the current task. MW has been reported to occur regularly in tasks ranging from simple visual search-paradigms to real-time driving. MW research has been measured most often within lab settings, however an understanding of how MW occurs in more naturalistic everyday tasks is highly valuable as well. This dissertation was motivated by research on the naturalness of experimental design (Tunnell, 1977) and the practice of cognitive ethology, which aims to understand cognition and behaviour under real-world settings (Kingstone, Smilek, & Eastwood, 2008; Kingstone, Smilek, Ristic, Kelland Friesen, & Eastwood, 2003). The goal was to investigate whether the methods, measurements, and settings used to study mind wandering reflect the natural experience as it occurs inside and outside of the lab. In Experiments 1-5, I examine whether MW report style (self-caught versus probe-caught) influences reports made in terms of frequency or content characteristics. Experiments 6-8 extended this investigation to more naturalistic settings. Experiments 9 and 10 consider the role of distraction in MW, within lab and uncontrolled settings. Results from this body of work reveals that MW is relatively stable regardless of whether it is revealed through probe-caught or self-caught methodologies, that peer presence but not lecture features influence MW rates, and that other forms of inattention (i.e., distraction) do not necessarily occur at the same rate as MW. The findings of this thesis open new avenues and methods for the investigation of MW in controlled and natural settings.

description: ProblemMental ill health in the United Kingdom of Great Britain and Northern Ireland has been a major driver of labour market exclusion through sickness absence, reduced productivity and job loss.ApproachA government-supported programme for improving access to psychological therapies was launched in 2008 and expanded across England in 2010. The aim was to provide evidence-based treatments for people with common mental disorders through three principal strategies: (i) routine session-by-session outcome monitoring; (ii) integration with the wider care system; and (iii) delivery of psychological therapies as part of a stepped-care approach.Local settingAccess to effective psychological therapies was previously low in the United Kingdom. In 2010, only about 35% of people with moderately severe mental disorders were in specialist or non-specialist treatment.Relevant changesThe accessibility of quality mental health services has increased, as has the efficiency of the country's mental health system. The numbers of people entering treatment have increased steadily from 0.43 million in 2012-2013 to 1.09 million in 2018-2019. The recovery rate of patients in treatment increased from 42.8% to 52.1% during 2012-2018. The number of people moved off sick pay and benefits rose from 3683 to 18 039 over the same period.Lessons learntA clinical guideline on psychological therapies is a prerequisite for increasing the accessibility and efficiency of mental health services. An integrated approach allows mental health services to have better reach. Routine collection of patient-level outcome data plays an important role in the value and function of the mental health care system.

description: Recently, Delfino and Viti have examined the factorization of the three-point density correlation function P_3 at the percolation point in terms of the two-point density correlation functions P_2. According to conformal invariance, this factorization is exact on the infinite plane, such that the ratio R(z_1, z_2, z_3) = P_3(z_1, z_2, z_3) [P_2(z_1, z_2) P_2(z_1, z_3) P_2(z_2, z_3)]^{1/2} is not only universal but also a constant, independent of the z_i, and in fact an operator product expansion (OPE) coefficient. Delfino and Viti analytically calculate its value (1.022013...) for percolation, in agreement with the numerical value 1.022 found previously in a study of R on the conformally equivalent cylinder. In this paper we confirm the factorization on the plane numerically using periodic lattices (tori) of very large size, which locally approximate a plane. We also investigate the general behavior of R on the torus, and find a minimum value of R approx. 1.0132 when the three points are maximally separated. In addition, we present a simplified expression for R on the plane as a function of the SLE parameter kappa.

description: "Anode-free" batteries present a significant advantage due to their substantially higher energy density and ease of assembly in a dry air atmosphere. However, issues involving lithium dendrite growth and low cycling Coulombic efficiencies during operation remain to be solved. Solid electrolyte interphase (SEI) formation on Cu and its effect on Li plating are studied here to understand the interplay between the Cu current collector surface chemistry and plated Li morphology. A native interphase layer (N-SEI) on the Cu current collector was observed with solid-state nuclear magnetic resonance spectroscopy (ssNMR) and electrochemical impedance spectroscopy (EIS). Cyclic voltammetry (CV) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) studies showed that the nature of the N-SEI is affected by the copper interface composition. An X-ray photoelectron spectroscopy (XPS) study identified a relationship between the applied voltage and SEI composition. In addition to the typical SEI components, the SEI contains copper oxides (Cu x O) and their reduction reaction products. Parasitic electrochemical reactions were observed via in situ NMR measurements of Li plating efficiency. Scanning electron microscopy (SEM) studies revealed a correlation between the morphology of the plated Li and the SEI homogeneity, current density, and rest time in the electrolyte before plating. Via ToF-SIMS, we found that the preferential plating of Li on Cu is governed by the distribution of ionically conducting rather than electronic conducting compounds. The results together suggest strategies for mitigating dendrite formation by current collector pretreatment and controlled SEI formation during the first battery charge.

description: Ongoing and upcoming surveys in x-rays and SZE are expected to jointly detect many clusters due to the large overlap in sky coverage. We show that, these clusters can be used as an ensemble of rulers to estimate the angular diameter distance, d_A(z). This comes at no extra observational cost, as these clusters form a subset of a much larger sample, assembled to build cluster number counts dn/dz. On using this d_A(z), the dark energy constraints can be improved by factors of 1.5 - 4, over those from just dn/dn. Even in the presence of a mass follow-up of 100 clusters (done for mass calibration), the dark energy constraints can be further tightened by factors of 2 - 3 . Adding d_A(z) from clusters is similar to adding d_L(z), from the SNe observations; for eg., dn/dn (from ACT/SPT) plus d_A(z) is comparable to dn/dz plus d_L(z) in constraining Omega_m and sigma_8.

description: The goal of this APE is to coordinate and plan the development of spectroscopic software within the astropy project. The requirements for spectroscopic tools include handling and reducing observations, different types of analysis, and visualization of spectra. The goal of this APE is to provide a framework that different astronomy packages can use to coordinate the development of spectroscopic tools. The idea is a set of foundational packages that can then be extended to build other tools. As part of this coordination effort, this APE provides specifications for a Spectrum1D class. Note that "1D" is not mean to indicate a single spectrum - the object can also be a collection of spectra. This class will then provide a standard interface for 1D spectra that will be the basis for interoperability.

description: The goal of this study was to investigate the effect of thermal treatment (200, 400, and 600 °C) on the adsorption capacity of a natural clinoptilolite-rich zeolite (NZ) of different particle sizes for methylene blue removal from aqueous solution. The physical properties and chemical composition of the natural zeolites treated at several temperatures were determined. Powder X-ray diffraction, Brunauer–Emmett–Teller, and scanning electron microscopy were used to characterize the thermally treated zeolites. X-ray diffraction showed that the main crystalline phases of the thermally treated zeolites were clinoptilolite-Na, quartz, muscovite, and albite. The equilibrium measurements were analyzed using Langmuir, Freundlich, and Dubinin-Radushkevich isotherms. The experimentally fitted Freundlich isotherm was a better fit than the Langmuir model for methylene blue adsorption onto the thermally treated zeolites. The adsorption of methylene blue on the thermally treated natural zeolites was shown to involve chemisorption.

description: We present the results of a combined experimental and theoretical investigation of the surface-tension-driven coalescence of flexible structures. Specifically, we consider the dynamics of the rise of a wetting liquid between flexible sheets that are clamped at their upper ends. As the elasticity of the sheets is progressively increased, we observe a systematic deviation from the classical diffusive-like behaviour: the time to reach equilibrium increases dramatically and the departure from classical rise occurs sooner, trends that we elucidate via scaling analyses. Three distinct temporal regimes are identified and subsequently explored by developing a theoretical model based on lubrication theory and the linear theory of plates. The resulting free-boundary problem is solved numerically and good agreement is obtained with experiments.

access to antimicrobials

description: Background: Antimicrobial resistance (AMR) is one of the most important global health crises in recent times and is driven primarily by antimicrobial consumption. In East Africa, there is a paucity of data regarding the knowledge, attitudes, and practices (KAP) related to antimicrobial use (AMU). We investigate the ways in which antimicrobial users in the veterinary sector accessed veterinary antimicrobials, and common behaviors of veterinary antimicrobial users and prescribers associated with AMU and AMR. Methods: In total, 70 farmers, staff at 49 agricultural-veterinary antimicrobial shops (agrovet staff) and 28 veterinary animal healthcare workers or veterinary surgeons (veterinary professionals) were interviewed in Busia county, western Kenya in 2016 using a standard questionnaire as a framework for structured interviews. Data recorded included participant demographics, level of education, access to and sources of veterinary antimicrobials, prescribing patterns, and knowledge of AMR and antimicrobial withdrawal periods. Results: The majority of antimicrobials were accessed through informal means, purchased from agroveterinary shops; more than half of staff did not hold nationally mandated qualifications to advise on or sell veterinary antimicrobials. Approximately 40% of veterinary antimicrobials were sold without a prescription and it was noted that both price and customer preference were important factors when selling antimicrobials in almost all agrovet shops. Knowledge of the dangers associated with AMR and AMU were mostly superficial. Treatment failure occurred often, and there was a lack of differentiation between AMR and simply treatment failure. Conclusion: In this study area in East Africa with high-density human and livestock populations, AMU was primarily for maintenance of livestock health. These findings have highlighted several aspects surrounding inappropriate access to antimicrobials, and as such require attention from policy makers concerned with AMR in both livestock and human medicine sectors. Improving prescribing practices and ensuring a minimum level of general education and awareness of prescribers, as well as expanding the role of agrovet staff in antimicrobial stewardship programmes, may help begin to mitigate the maintenance and transmission of AMR, particularly amongst livestock.

description: The present work is devoted to the study of the supernova remnant and its neutron star XMMU J172054. 5-372652. The paper analyzes observations in 2009 and 2018, data for this system obtained by the Chandra x ray observatory. The analysis showed that the neutron star G350. 1-0. 3 with M = 1, 4 Msun, R = 13 MS, dist = 4, 5 KPC, we also measured its temperature in two groups: the first group, including observations made in 2009, and the second group, including 5 observations made at different times of the year 2018. In addition, in this work, we study all important aspects of the supernova remnants of G350. 1-0. 3, and obtain their spectra using the collided plasma, nonequilibrium, constant temperature (VNEI) model, which assumes a constant temperature and a single ionization parameter. It gives a characteristic of the spectrum, but is not a physical model, we will precede the spectra obtained using this model.

description: The relation between the separability of a system of charged particles in a uniform magnetic field and Galilean symmetry is revisited using Duval's "Bargmann framework". If the charge-to-mass ratios of the particles are identical, $e_a/m_a=ε$ for all particles, then the Bargmann space of the magnetic system is isometric to that of an anisotropic harmonic oscillator. Assuming that the particles interact through a potential which only depends on their relative distances, the system splits into one representing the center of mass plus a decoupled internal part, and can be mapped further into an isolated system using Niederer's transformation. Conversely, the manifest Galilean boost symmetry of the isolated system can be "imported" to the oscillator and to the magnetic systems, respectively, to yield the symmetry used by Gibbons and Pope to prove the separability. For vanishing interaction potential the isolated system is free and our procedure endows all our systems with a hidden Schroedinger symmetry, augmented with independent internal rotations. All these properties follow from the cohomological structure of the Galilei group, as explained by Souriau's "décomposition barycentrique"

description: Magnetic dispersive microsolid phase extraction (MDMSPE) was coupled with dispersive liquid–liquid microextraction (DLLME) for the separation and preconcentration of arsenic(V) and arsenic(III) prior to graphite furnace atomic absorption spectrometry detection. In the first step, magnetic ZnFe2O4 nanotubes were employed for adsorbing arsenic(V). The adsorbent was separated from the aqueous phase by the use of an external magnetic field. Next, arsenic(III) in the upper aqueous phase from MDMSPE was enriched by DLLME. Samples were prepared with artificial gastric juice to avoid inter-conversion of the determined species. The parameters affecting the separation and preconcentration of the determined species were optimized. The detection limits of this protocol were determined to be 1.3 and 2.0 pg mL−1 for arsenic(III) and arsenic(V) with relative standard deviations of 4.5% and 5.6% for a concentration of 1.0 ng mL−1 (n = 9). The enrichment factors were equal to 175-fold for arsenic(III) and 163-fold for arsenic(V). The developed protocol was employed for the determination of arsenic(III) and arsenic(V) in dairy products without preoxidation or prereduction. The recoveries of spiked samples were from 90.8% to 105%. A milk powder certified reference material was analyzed by this approach and the measured results were in good agreement with the certified value.

description: Abstract: Mutation accumulation in somatic cells contributes to cancer development and is proposed as a cause of aging. DNA polymerases Pol ε and Pol δ replicate DNA during cell division. However, in some cancers, defective proofreading due to acquired POLE/POLD1 exonuclease domain mutations causes markedly elevated somatic mutation burdens with distinctive mutational signatures. Germline POLE/POLD1 mutations cause familial cancer predisposition. Here, we sequenced normal tissue and tumor DNA from individuals with germline POLE/POLD1 mutations. Increased mutation burdens with characteristic mutational signatures were found in normal adult somatic cell types, during early embryogenesis and in sperm. Thus human physiology can tolerate ubiquitously elevated mutation burdens. Except for increased cancer risk, individuals with germline POLE/POLD1 mutations do not exhibit overt features of premature aging. These results do not support a model in which all features of aging are attributable to widespread cell malfunction directly resulting from somatic mutation burdens accrued during life.

description: A critical review of hadronic tau decay data based determinations of |V_{us}| is given, focussing on the impact of the slow convergence of the integrated D=2 OPE series for the conventional flavor-breaking sum rule determination and the potential role of as-yet-unmeasured multiparticle contributions to the strange spectral distribution. Additional information obtainable from analyses of inclusive strange decay data alone, and from mixed electroproduction-tau sum rules with much reduced OPE uncertainties, is also discussed. Self-consistency tests are shown to favor determinations which reduce somewhat discrepancies with 3-family unitarity expectations.

description: We theoretically propose a scheme for a spin quantum bit based on a double quantum dot contacted to ferromagnetic elements. Interface exchange effects enable an all electric manipulation of the spin and a switchable strong coupling to a superconducting coplanar waveguide cavity. Our setup does not rely on any specific band structure and can in principle be realized with many different types of nanoconductors. This allows to envision on-chip single spin manipulation and read-out using cavity QED techniques.
