description: This paper presents a new method to estimate systematic errors in the maximum-likelihood regression of count data. The method is applicable in particular to X-ray spectra in situations where the Poisson log-likelihood, or the Cash goodness-of-fit statistic, indicate a poor fit that is attributable to overdispersion of the data. Overdispersion in Poisson data is treated as an intrinsic model variance that can be estimated from the best-fit model, using the maximum-likelihood Cmin statistic. The paper also studies the effects of such systematic errors on the Delta C likelihood-ratio statistic, which can be used to test for the presence of a nested model component in the regression of Poisson count data. The paper introduces an overdispersed chi-square distribution that results from the convolution of a chi-square distribution that models the usual Delta C statistic, and a zero-mean Gaussian that models the overdispersion in the data. This is proposed as the distribution of choice for the Delta C statistic in the presence of systematic errors. The methods presented in this paper are applied to XMM-Newton data of the quasar 1ES 1553+113 that were used to detect absorption lines from an intervening warm-hot intergalactic medium (WHIM). This case study illustrates how systematic errors can be estimated from the data, and their effect on the detection of a nested component, such as an absorption line, with the Delta C statistic.

Biochemical riboflavin status and its predictors in adult women aged 51-70 years in Metro Vancouver
Creators: name: Zubair, Mohammad Saroar

Year: 2021

description: Background: Riboflavin, or vitamin B-2, functions as a coenzyme in numerous metabolic pathways and is essential for adequate cell growth. Riboflavin status has been shown to be inversely associated with the risk of cardiovascular diseases and cancers. Erythrocyte glutathione reductase activation coefficient (EGRac) is a functional indicator and considered as the ‘gold standard’ biomarker of riboflavin status. Previous studies have reported a high prevalence of biochemical riboflavin deficiency but a low prevalence of dietary inadequacy in adults aged ≥65 years. In Canada, 3% of adult women aged 51-70 years had inadequate dietary riboflavin intake; however, data are lacking on biochemical riboflavin status. Objectives: The objectives of this research were to determine the biochemical riboflavin status, and to identify the dietary, demographic and lifestyle predictors of riboflavin status in adult women (aged 51-70 years) in Metro Vancouver. Methods: This secondary analysis used data and biospecimens from a cross-sectional study of a convenience sample of 223 adult women age 51-70 years. A fasting blood sample, blood pressure measurements, sociodemographic, anthropometric and dietary intake data were collected during a single-day study visit. Riboflavin status was measured using EGRac. Plasma riboflavin concentration was analyzed using an in-house validated liquid chromatography-tandem mass spectrometry assay. Results: Overall, 29% of the study population had riboflavin deficiency (EGRac ≥1.4) and 22% had suboptimal status (EGRac ≥1.3 and <1.4). However, only 4.7% did not meet their dietary riboflavin requirements (i.e. riboflavin intake ≥0.9 mg/day). Riboflavin intake from food and supplements was significantly correlated with EGRac (Spearman-rho=-0.55; p<0.001), and plasma riboflavin concentration (Spearman-rho=0.45; p <0.001). Total riboflavin intake and Chinese ethnicity were significant predictors of biochemical riboflavin status. Conclusion: This study is the first to determine biochemical riboflavin status of free-living adult women aged 51-70 years in Metro Vancouver and Canada. It provides new information and preliminary data for future research including information on possible predictors of riboflavin deficiency in this population group. High prevalence of biochemical riboflavin deficiency and suboptimal status among the study population may be a cause for concern. The discrepancy between the diagnosis of biochemical riboflavin deficiency and total riboflavin intake inadequacy warrants more research.

description: Hybrid magnets are currently under consideration as an economically viable option towards 20 T dipole magnets for next generation of particle accelerators. In these magnets, High Temperature Superconducting (HTS) materials are used in the high field part of the coil with so-called insert coils, and Low Temperature Superconductors (LTS) like Nb3Sn and Nb-Ti superconductors are used in the lower field region with so-called outsert coils. The attractiveness of the hybrid option lays on the fact that, on the one hand, the 20 T field level is beyond the Nb3Sn practical limits of 15-16 T for accelerator magnets and can be achieved only via HTS materials; on the other hand, the high cost of HTS superconductors compared to LTS superconductors makes it advantageous exploring a hybrid approach, where the HTS portion of the coil is minimized. We present in this paper an overview of different design options aimed at generating 20 T field in a 50 mm clear aperture. The coil layouts investigated include the Cos-theta design (CT), with its variations to reduce the conductor peak stress, namely the Canted Cos-theta design (CCT) and the Stress Management Cos-theta design (SMCT), and, in addition, the Block-type design (BL) including a form of stress management and the Common-Coil design (CC). Results from a magnetic and mechanical analysis are discussed, with particular focus on the comparison between the different options regarding quantity of superconducting material, field quality, conductor peak stress, and quench protection.

description: Gyrokinetic field theory is addressed in the context of a general Hamiltonian. The background magnetic geometry is static and axisymmetric, and all dependence of the Lagrangian upon dynamical variables is in the Hamiltonian or in free field terms. Equations for the fields are given by functional derivatives. The symmetry through the Hamiltonian with time and toroidal angle invariance of the geometry lead to energy and toroidal momentum conservation. In various levels of ordering against fluctuation amplitude, energetic consistency is exact. The role of this in underpinning of conservation laws is emphasised. Local transport equations for the vorticity, toroidal momentum, and energy are derived. In particular, the momentum equation is shown for any form of Hamiltonian to be well behaved and to relax to its magnetohydrodynamic (MHD) form when long wavelength approximations are taken in the Hamiltonian. Several currently used forms, those which form the basis of most global simulations, are shown to be well defined within the gyrokinetic field theory and energetic consistency.

description: A microscopic description of the zero energy two-body ground state and many-body static properties of anisotropic homogeneous gases of bosonic dipoles in two dimensions at low densities is presented and discussed. By changing the polarization angle with respect to the plane, we study the impact of the anisotropy, present in the dipole--dipole interaction, on the energy per particle, comparing the results with mean field predictions. We restrict the analysis to the regime where the interaction is always repulsive, although the strength of the repulsion depends on the orientation with respect to the polarization field. We present a series expansion of the solution of the zero energy two-body problem which allows us to find the scattering length of the interaction and to build a suitable Jastrow factor that we use as a trial wave function for both a variational and diffusion Monte Carlo simulation of the infinite system. We find that the anisotropy has an almost negligible impact on the ground state properties of the many-body system in the universal regime where the scattering length governs the physics of the system. We also show that scaling in the gas parameter persists in the dipolar case up to values where other isotropic interactions with the same scattering length yield different predictions.

description: Constraints on the formation and evolution of the Milky Way Galaxy require multi-dimensional measurements of kinematics, abundances, and ages for a large population of stars. Ages for luminous giants, which can be seen to large distances, are an essential component of studies of the Milky Way, but they are traditionally very difficult to estimate precisely for a large dataset and often require careful analysis on a star-by-star basis in asteroseismology. Because spectra are easier to obtain for large samples, being able to determine precise ages from spectra allows for large age samples to be constructed, but spectroscopic ages are often imprecise and contaminated by abundance correlations. Here we present an application of a variational encoder-decoder on cross-domain astronomical data to solve these issues. The model is trained on pairs of observations from APOGEE and Kepler of the same star in order to reduce the dimensionality of the APOGEE spectra in a latent space while removing abundance information. The low dimensional latent representation of these spectra can then be trained to predict age with just $\sim$ 1,000 precise seismic ages. We demonstrate that this model produces more precise spectroscopic ages ($\sim$ 22% overall, $\sim$ 11% for red-clump stars) than previous data-driven spectroscopic ages while being less contaminated by abundance information (in particular, our ages do not depend on [$α$/M]). We create a public age catalog for the APOGEE DR17 data set and use it to map the age distribution and the age-[Fe/H]-[$α$/M] distribution across the radial range of the Galactic disk.

description: We present the design and fabrication of nanobeam photonic crystal cavities in single crystal diamond for applications in cavity quantum electrodynamics. First, we describe three-dimensional finite-difference time-domain simulations of a high quality factor (Q ~ 10^6) and small mode volume (V ~ 0.5 (λ/n)^3) device whose cavity resonance corresponds to the zero-phonon transition (637nm) of the Nitrogen-Vacancy (NV) color center in diamond. This high Q/V structure, which would allow for strong light-matter interaction, is achieved by gradually tapering the size of the photonic crystal holes between the defect center and mirror regions of the nanobeam. Next, we demonstrate two different focused ion beam (FIB) fabrication strategies to generate thin diamond membranes and nanobeam photonic crystal resonators from a bulk crystal. These approaches include a diamond crystal "side-milling" procedure as well as an application of the "lift-off" technique used in TEM sample preparation. Finally, we discuss certain aspects of the FIB fabrication routine that are a challenge to the realization of the high-Q/V designs.

description: We propose an approach to sensitively probe the chirality of molecules by measuring their coherent optical absorption spectra. It is shown that quantum dynamics of the cyclic three-level chiral molecules driven by appropriately-designed external fields is total-phase dependent. This will result in chirality-dependent absorption spectra for the probe field. As a consequence, these absorption spectra can be utilized to identify molecular chirality and determinate enantiomer excess. The feasibility of the proposal with chiral molecules confined in hollow-core photonic crystal fiber (HC-PCF) is also discussed.

This verified the conjectured matter fields BCJ relation. We also show that color reflection relation and U(1)-decoupling relation are special cases of KK relation, if we consider the KK relation as a general relation, then the former two relations come out naturally as the special cases.

description: Relative phases of amplitudes for $D$ meson decays to a light pseudoscalar meson $P$ and a light vector meson $V$ decaying to two pseudoscalar mesons will lead to characteristic interferences on the three-body Dalitz plot. These phases may be compared with predictions of a flavor-symmetric treatment which extracts contributing amplitudes and their relative phases from a fit to $D \to PV$ decay rates. Good agreement was found previously for the cases of $D^0 \to K^- π^+ π^0$ and $D^0 \to π^+ π^- π^0$. The present work is devoted to the decays $D^0 \to K_S π^+ π^-$ and $D^0 \to π^0 K^+ K^-$, for which agreement is not found. Several suggestions are offered for this discrepancy.

A two-step bio-oil upgrading study using carbon supported molybdenum carbide catalysts
Creators: name: Liu, Shida
Publisher: name: University of British Columbia
Year: 2019

description: A two-step bio-oil upgrading process has been investigated using carbon supported molybdenum carbide catalysts. The waste materials, petcoke (PC) and biochar (BC) were activated to yield the Mo₂C/APC and Mo₂C/ABC catalysts (APC – activated petcoke and ABC – activated biochar). These catalysts presented very high (approximately 85%) direct deoxygenation (DDO) selectivity in the hydrodeoxygenation (HDO) reaction. Furthermore, the Mo₂C/APC catalysts with low Mo loading (1 and 2 wt %) were acid washed in H₂SO₄ and both the Mo₂C/APC catalysts and the acid treated Mo₂C/APC catalysts were active for the esterification of acetic acid and 1-butanol. The hydrodeoxygenation (HDO) of 2-methoxyphenol over Pd, Ru and Mo₂C catalysts supported on activated charcoal (AC) was compared. The overall 2-methoxyphenol consumption rate decreased in the order Pd > Ru > Mo₂C due to Mo₂C’s lower hydrogenation activity. Mo₂C was the most efficient in terms of O-removal with minimal H₂ consumption. To enhance the hydrogenation activity of the Mo₂C catalysts, promotion of a 10 % Mo₂C/carbon catalyst with 1%Cu, 1%Ni and 1%Pd was assessed for the HDO of dibenzofuran (DBF). The addition of Ni and Pd decreased the temperature required for the removal of the oxygen layer from the Mo₂C that is formed during catalyst passivation. This enhanced ability of the promoted catalyst to hydrogenate surface oxide species suggests that the same catalyst could improve the stability of the catalyst during HDO. Finally, the catalysts were assessed in a two-step bio-oil upgrading process that combined esterification and hydrodeoxygenation to improve the bio-oil fuel quality. In the first step, the Mo₂C catalysts were shown to have sufficient acidity so as to catalyse esterification reactions at 180 °C and 10.3 MPa that stabilized the bio-oil. In the 2nd step of the upgrading process, the best Mo₂C catalyst 1Ni-10Mo₂C/ABC achieved 69% HDO with an overall carbon yield of 67% when operated at 350 °C and 15.0 MPa. The Ni-Mo₂C catalysts are proven to be promising catalysts for the proposed two-step bio-oil upgrading.

description: Imbalanced data sets containing much more background than signal instances are very common in particle physics, and will also be characteristic for the upcoming analyses of LHC data. Following up the work presented at ACAT 2008, we use the multivariate technique presented there (a rule growing algorithm with the meta-methods bagging and instance weighting) on much more imbalanced data sets, especially a selection of D0 decays without the use of particle identification. It turns out that the quality of the result strongly depends on the number of background instances used for training. We discuss methods to exploit this in order to improve the results significantly, and how to handle and reduce the size of large training sets without loss of result quality in general. We will also comment on how to take into account statistical fluctuation in receiver operation characteristic curves (ROC) for comparing classifier methods.

description: A computational procedure is developed for the efficient calculation of derivatives of integrals over non-separable Gaussian-type basis functions, used for the evaluation of gradients of the total energy in quantum-mechanical simulations. The approach, based on symbolic computation with computer algebra systems and automated generation of optimized subroutines, takes full advantage of sparsity and is here applied to first energy derivatives with respect to nuclear displacements and lattice parameters of molecules and materials. The implementation in the \textsc{Crystal} code is presented and the considerably improved computational efficiency over the previous implementation is illustrated. To this purpose, three different tasks involving the use of analytical forces are considered: i) geometry optimization; ii) harmonic frequency calculation; iii) elastic tensor calculation. Three test case materials are selected as representatives of different classes: i) a metallic 2D model of the Cu (111) surface; ii) a wide-gap semiconductor ZnO crystal, with a wurtzite-type structure; and iii) a porous metal-organic crystal, namely the ZIF-8 Zinc-imidazolate framework. Finally, it is argued that the present symbolic approach is particularly amenable to generalizations, and its potential application to other derivatives is sketched.
TO LIVE WITH ENSET: A CASE FROM THE GAMO HIGHLANDS OF SOUTHERN ETHIOPIA
Creators: name: EYOB DEFERSHA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Enset (Ensete Ventricosum) is a perennial crop that feed over 10 million people in the Southern
Ethiopia and not known outside Ethiopia as food crop. This plant is related to banana (Mussa)
family and both the pseudostem and corm are pulped for food (kocho) and fiber.  Many
researchers have conducted investigations on the production, utilization, and management of
enset in the SNNPRS. However, all of the researches on enset to date have focused on specific
aspects of cultivation rather than looking at socio-cultural contexts. Thus, the main objective of
the study is  to investigate the existing, socio-cultural values of enset in Gamo highland of
southern Ethiopia.  The location is the Zollo kebele of the Gamo Highlands.  The fieldwork
conducted used different types of data collection: field observation, photography, in-depth
interviews, focus group discussions, and use of available documents. Enset as one of other
farming product it is cultivated by the farmers the whole year. The unique style of enset farming
in the Gamo Highlands was developed over countless generations, shaped by the local
landscape, climate and lifestyle of the people. The traditional enset farming in the study area
includes planting suckers, managing the overall life cycle, identifying different landraces,
harvesting and processing it. The study identified unique enset human interaction among Zollo
people. Enset play vital role for the existence of different social and cultural values of Zollo
people.  At the end, the case study identifies major challenges to enset farming in  the Gamo
highlands, which threaten its traditional role as a means to cope with the vicissitudes of life. This
includes enset diseases, shrink of enset farming land and lack of organic fertilizer or animal
dung. Increasing the number livestock in the community and taking appropriate interventions on
preventing enset disease  is recommended  to ensure continuation of the enset farming on which
the local food need is mostly relying.

description: Inner regions of protoplanetary disks host many complex physical processes such as star-disk interactions, magnetic fields, planet formation, and the migration of new planets. To directly study this region requires milli-arcsecond angular resolution, beyond the diffraction limit of the world's largest optical telescopes and even too small for the mm-wave interferometer ALMA. However, we can use infrared interferometers to image the inner astronomical unit. Here, we present new results from the CHARA and VLTI arrays for the young and luminous Herbig Be star HD 190073. We detect a sub-AU cavity surrounded by a ring-like structure that we interpret as the dust destruction front. We model the shape with 6 radial profiles, 3 symmetric and 3 asymmetric, and present a model-free image reconstruction. All the models are consistent with a near face-on disk with inclination $\lesssim 20^\circ$, and we measure an average ring radius of 1.4 $\pm 0.2$ mas (1.14 AU). Around $48\%$ of the total flux comes from the disk with ~$15\%$ of that emission appearing to emerge from inside the inner rim. The cause of emission is still unclear, perhaps due to different dust grain compositions or gas emission. The skewed models and the imaging point to an off-center star, possibly due to binarity. Our image shows a sub-AU structure, which seems to move between the two epochs inconsistently with Keplerian motion and we discuss possible explanations for this apparent change.

description: In a well-stirred system undergoing chemical reactions, fluctuations in the reaction propensities are approximately captured by the corresponding chemical Langevin equation. Within this context, we discuss in this work how the Kramers escape theory can be used to predict rare events in chemical reactions. As an example, we apply our approach to a recently proposed model on cell proliferation with relevance to skin cancer [P.B. Warren, Phys. Rev. E {\bf 80}, 030903 (2009)]. In particular, we provide an analytical explanation for the form of the exponential exponent observed in the onset rate of uncontrolled cell proliferation.

STRATEGIES TO SURVIVE SOCIAL - ECOLOGICAL RISKS  AMONG KONSO OF SOUTHERN ETHIOPIA
Creators: name: AYANO GUDANO
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Konso people are known for their intensive agriculture and conservation practices that
provide solutions to social and environmental problems. This research presents an
empirical study on strategies to survive social-ecological risks among Konso of southern
Ethiopia. The main aim of the study was to investigate how the Konso adults perceive
social-ecological risks, the strategies they employ to deal with these  risks and the
mechanisms used to learn these strategies. To address the objectives of the  study, both
qualitative and quantitative methods were employed which includes: field observation,
free lists, semi-structured interviews and focus group discussions. The result of the study
revealed that Konso adults have clear understanding about the risky times they
experienced. The culture of sharing experiences and relating difficult times with natural
and social incidences contributed to their perception of social-ecological risks. The
research also identified that food scarcity, conflict, long dry season, and disease are the
salient risks of the study area. Besides, saving, petty trade, spinning cotton, eating wild
plants, birta, malota, wage labor, qapsisa (mortgage) are among the short term
strategies employed to mitigate food scarcity, whereas intensive agriculture, social
networks (i.e. labor organization), intercropping, mixed farming, diversification of
farming and non-farming activities and planting fruit plants are adaptive strategies
developed through time to increase their chance of survival  in face of risky times.
Moreover, the research result revealed that  adults  learn strategies  to  survive social-
ecological risks  primarily from parents through observation and listening of parents
teaching and advice. To this end, recommendations such as developing and implementing
strategies that initiate working culture, matching local coping and adaptive mechanisms
with scientific knowledge and sustaining indigenous of conflict resolution institutions
and/or mechanisms seems helpful.

description: We consider the massless limit of Higgs gravity, where the graviton becomes massive when the scalar fields acquire expectation values. We determine the Vainshtein scale and prove that massive gravity smoothly goes to General Relativity below this scale. We find that the Vainshtein scale depends on the particular action of scalar fields used to give mass to the graviton.

TRADITIONAL MARRIAGE PRACTICES AMONG MASHOLE  COMMUNITY IN SNNPR OF ETHIOPIA
Creators: name: Genzebe Gezahegn
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Marriage can  be defined as a series of customs formalizing the relationship between adult
partners within the family and socially approved union between two or more adult partners that
regulates the sexual and economic rights and obligations between them. It has customs, rules,
and obligations that establish a socially endorsed relationship between the kin groups of the
married partners. The traditional marriage practices are on disappearing as a result of the quick
process of economic growth, globalization, modernization and religions. This leads to the loss of
identity. As a result many scholars make their own contribution by documenting, displaying and
promoting distinctive features of different ethnic group identity. For the matter, this study aimed
to understand, provide detailed data of traditional marriage practice of the Mashole through
qualitative data gathering and analysis method. Therefore, Mashole has four types of traditional
marriage practices such as Logashipota, Tina, Dahal, and Boliqala marriage.  However those
traditional marriage practices are on disappearing as the result of infrastructure fulfillment,
government, nongovernmental organization and religious expansion. Therefore government,
community members and other stakeholders are suggested to plan for develop and promote the
cultural aspects of Mashole community.
A sensitive APEX and ALMA CO(1-0), CO(2-1), CO(3-2), and [CI](1-0) spectral survey of 40 local (U)LIRGs

description: We present a high sensitivity spectral line survey of CO(1-0), CO(2-1), CO(3-2) and [CI](1-0) in 40 local (ultra) luminous infrared galaxies ((U)LIRGs), all with previous Herschel OH119 $μ$m observations. We use single-dish observations (PI and archival) conducted with APEX, complemented with ALMA and ACA data. We study the total emission and pay special attention to the extended low-surface brightness components. We find a tight correlation between low-J CO and [CI] line luminosities suggesting their emission arise from similar regions, at least when averaged over galactic scales. We estimate a median CO-to-H$_2$ conversion factor of $1.7\pm 0.5$ M$_{\odot}$ (K km s$^{-1}$ pc$^2)^{-1}$ for ULIRGs, using [CI] as an independent tracer. We derive median galaxy-integrated CO line ratios ($r_{21}$, $r_{31}$ and $r_{32}$), as well as $r_{CICO}$, significantly higher than normal star forming galaxies, confirming the exceptional molecular gas properties of ULIRGs. We find that $r_{21}$ and $r_{32}$ are poor tracers of CO excitation in ULIRGs, while $r_{31}$ shows a positive trend with $L_{IR}$ and SFR, and a negative trend with the H$_2$ gas depletion timescales ($τ_{dep}$). When studying CO line ratios as a function of gas kinematics, we find a positive relation between $r_{21}$ and $σ_v$, which can be explained by CO opacity effects. We find that the linewidths of [CI] lines are ~10% narrower than CO lines, which may suggest that the low optical depth of [CI] can challenge its detection in diffuse, low-surface brightness outflows, and so its use as a tracer of CO-dark H$_2$ gas in these components. Finally, we find that higher $L_{AGN}$ are associated to longer $τ_{dep}$, consistent with the hypothesis that AGN feedback may reduce the efficiency of star formation.

Exact ground state properties of the one-dimensional Coulomb gas

description: The ground state properties of a single-component one-dimensional Coulomb gas are investigated. We use Bose-Fermi mapping for the ground state wave function which permits to solve the Fermi sign problem in the following respects (i) the nodal surface is known, permitting exact calculations (ii) evaluation of determinants is avoided, reducing the numerical complexity to that of a bosonic system, thus allowing simulation of a large number of fermions. Due to the mapping the energy and local properties in one-dimensional Coulomb systems are exactly the same for Bose-Einstein and Fermi-Dirac statistics. The exact ground state energy has been calculated in homogeneous and trapped geometries by using the diffusion Monte Carlo method. We show that in the low-density Wigner crystal limit an elementary low-lying excitation is a plasmon, which is to be contrasted with the large-density ideal Fermi gas/Tonks-Girardeau limit, where low lying excitations are phonons. Exact density profiles are confronted to the ones calculated within the local density approximation which predicts a change from a semicircular to inverted parabolic shape of the density profile as the value of the charge is increased.
