description: Despite its mean apparent magnitude of m(v)=6.39, the evolutionary status of HD190390 (HR7671), a luminous F-type supergiant at high galactic latitude, is still not very clear, but in most papers a post-AGB classification is assumed. New observational material has been obtained with four different instruments and is presented here. An extensive abundance analysis based on high resolution, high signal-to-noise NTT+EMMI spectra confirms the metal deficiency of this object ([Fe/H]=-1.6), together with a high lithium content (log(Li)=1.9). A variability analysis based on Geneva photometry over seven years reveals beating with a period of +/-3000 days. It is, however, not clear whether this beating is caused by a stable triplet, or it is the consequence of small changes in the main frequency. More recent data obtained with the HIPPARCOS satellite and the Mercator telescope not only confirm the main period, but also support the presence of a second periodicity of 11 days, which was also found in the Geneva photometry. A conclusive evolutionary status of this object is not given, but alternative to the UU Her (i.e. post-AGB) status, a W Vir classification is discussed.

description: Improvements in agricultural productivity and reductions in marketing costs in Mozambique are analysed using a computable general equilibrium (CGE) model. The model incorporates detailed marketing margins and separates household demand for marketed and home-produced goods. Simulations improving agricultural technology and lowering marketing margins yield gains across the economy, but with differential impacts on factor returns. A combined scenario reveals significant synergy effects, as welfare gains exceed the sum of gains from the individual scenarios. Factor returns increase in roughly equal proportions, an attractive feature when assessing the political feasibility of policy initiatives.

description: We study the finite-size behavior of the low-lying excitations of spin-1/2 Heisenberg chains with dimerization and next-to-nearest neighbors interaction, J_2. The numerical analysis, performed using density-matrix renormalization group, confirms previous exact diagonalization results, and shows that, for different values of the dimerization parameter δ, the elementary triplet and singlet excitations present a clear scaling behavior in a wide range of \ell=L/ξ(where L is the length of the chain and ξis the correlation length). At J_2=J_2c, where no logarithmic corrections are present, we compare the numerical results with finite-size predictions for the sine-Gordon model obtained using Luscher's theory. For small δwe find a very good agreement for \ell > 4 or 7 depending on the excitation considered.

description: Recent developments in antiretroviral therapy (ART) have turned human immunodeficiency virus type 1 (HIV-1) infection from a potent killer to a chronic illness. However, HIV-1 drug resistance mutations (DRMs) hamper the efficacy of ART. When prescribing a treatment regimen, clinicians often do not check for DRMs, which hampers treatment efficacy. This is especially problematic in low-income areas, where there is a lack of routine drug resistance testing due to poor infrastructure. We propose the use of specific high-sensitivity enzymatic reporter unlocking (SHERLOCK) paired with CRISPR-Cas12b as a quick and inexpensive assay to detect HIV-1 DRMs. A guide RNA (gRNA) package development pipeline was generated to target HIV-1 protease DRMs. All protease DRMs and sequences were collected from the 2019 IAS-USA drug resistance mutations list and LANL HIV-1 Sequence Database, respectively. Synthetic protease sequences with artificial DRMs were also added as supplementary data. DRM-specific gRNAs were derived from all observed sequences containing that DRM. gRNAs were ranked according to F5-score and the top 128 gRNAs for each DRM were considered for packaging. gRNA packages would initially only contain the gRNA with the widest coverage. gRNAs would then be incrementally added based on the additional sensitivity (AS) they would provide and individual specificity (>85%). gRNAs would stop being added when the next best performing gRNA provides an AS of <1%. 194 gRNAs were used across all packages and 23/24 packages had >90% sensitivity. Further directions involve generalizing the pipeline for other HIV-1 gene targets and validating gRNA package performance in vitro.

description: We present an extension of the atomic frequency comb protocol that utilizes the Stark effect to perform noise-free, on-demand, control. An experimental realization of this protocol was implemented in the Pr$^{3+}$:Y$_2$SiO$_5$ solid-state system, and a recall efficiency of 38\% for a 0.8 $μ$s storage time was achieved. Experiments were performed with both bright pulses as well as weak-coherent states, the latter achieving a signal-to-noise ratio of $570 \pm 120$ using input pulses with an average photon number of $\sim 0.1$. The principal limitation for a longer storage time was found to be the minimum peak width attainable for Pr$^{3+}$:Y$_2$SiO$_5$. We employ an adaptation of an established atomic-frequency comb model to investigate an on-demand, wide-bandwidth, memory based on Eu$^{3+}$:Y$_2$SiO$_5$. From this we determine that a storage time as long as 100 $μ$s may be practical even without recourse to spin-wave storage.

Northern voices telling histories of Danish (post) colonialism
Creators: name: Cold-Ravnkilde, Sofie
Publisher: name: University of British Columbia
Year: 2009

description: Within postcolonial theoretical debates of former imperial nations Denmark is rarely mentioned. This thesis examines three novels that represent the colonial legacy of Danish colonisation in the Faroe Islands, Iceland, and Greenland: Barbara by Faroese-Danish Jorgen-Frantz Jacobsen, The Prowler by Icelandic-Danish-Canadian Kristjana Gunnars, and Smilla's Sense of Snow by Danish Peter Hoeg. Frantz Fanon argues in Black Skin, White Masks that colonisation leads to an inferiority complex in the colonised as they are forced to internalise the norms and values of the colonisers. While Fanon 's claim stems from his race based theory, he argues that such psychological inferiority can be the consequence for any colonised people. Farther, Fanon suggests that Whiteness as a concept is perceived a marker of cultural demeanour and financial capability, that is, Whiteness is as much a class divider as a racial one. The novels unveil how material reality, language, colonial discourse, and, in the case of Smilla's Sense of Snow, race work together to strengthen the divide between coloniser and colonised and thus feed internalisation. Holding these novels up against history and the cultural importance of written traditions, this thesis displays how the Danish history of colonialism has had detrimental, yet drastically different, effects for Iceland, the Faroe Islands, and Greenland and continue to have so for the latter two.

description: The multiplication of architecture description languages, component models and platforms implies a serious dilemma for component based software architects. On the one hand, they have to choose a language to describe concrete configurations which will be automatically deployed on execution platforms. On the other hand, they wish to capitalize their software architectures independently of any description languages or platforms. To solve this problem, we propose a multi personalities environment for the configuration and the deployment of component based applications. This environment is composed of a core capturing a canonical model of configuration and deployment, and a set of personalities tailored to languages and platforms. This paper details the architecture of such an environment and describes the personalities for the CORBA and Fractal component models.

We specifically investigate the possibility of defining a family of graph coherent states adapted to the canonical loop quantum gravity Hamiltonian. After discussing various aspects of the general framework and the choice of operators, we use the Euclidean part of the Hamiltonian operator to propose a generator of the generalized canonical structure, necessary to define the coherent states. We then apply the construction procedure, leading to a new family of graph coherent states partially adapted to the gravity Hamiltonian in loop quantum gravity.

Cosmological perturbations of brane-induced gravity and the vDVZ discontinuity on FLRW space-times

description: We investigate the cosmological perturbations of the brane-induced (Dvali-Gabadadze-Porrati) model which exhibits a van Dam-Veltman-Zakharov (vDVZ) discontinuity when linearized over a Minkowski background. We show that the linear brane scalar cosmological perturbations over an arbitrary Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time have a well defined limit when the radius of transition between 4D and 5D gravity is sent to infinity with respect to the background Hubble radius. This radius of transition plays for the brane-induced gravity model a role equivalent to the Compton wavelength of the graviton in a Pauli-Fierz theory, as far as the vDVZ discontinuity is concerned. This well defined limit is shown to obey the linearized 4D Einstein's equations whenever the Hubble factor is non vanishing. This shows the disappearance of the vDVZ discontinuity for general FLRW background, and extends the previously know result for maximally-symmetric space-times of non vanishing curvature. Our reasoning is valid for matter with simple equation of state such as a scalar field, or a perfect fluid with adiabatic perturbations, and involves to distinguish between space-times with a vanishing scalar curvature and space-times with a non vanishing one. We also discuss the validity of the linear perturbation theory, in particular for those FLRW space-times where the Ricci scalar is vanishing only on a set of zero measure. In those cases, we argue that the linear perturbation theory breaks down when the Ricci scalar vanishes (and the radius of transition is sent to infinity), in a way similar to what has been found to occur around sources on a Minkowski background.

description: The effect of a continuous model of correlations upon one-dimensional finite disordered quantum wires modeled by an array of delta-potentials, is analyzed. Although the model proposed is not able to include new truly extended states in the spectrum, the transport properties of a finite sample are noticeably improved due to the existence of states whose localization length is larger than the system size. This enhancement of transmission is maximized for relatively short chains.

We investigate the phase transitions by means of average-vortex-approximation. We find that the vortex lattice consists of a vortex array with a hole in the center of the cloud as the rotating frequency $Ω$ increases and the vortex becomes invisible when $Ω$ reaches some value.

This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary intermediate variable (called mediator) and a direct effect running via other causal mechanisms. We identify average and quantile direct and indirect effects for various subgroups under the condition that the outcome is monotonic in the unobserved heterogeneity and that the distribution of the latter does not change over time conditional on the treatment and the mediator. We also provide a simulation study and two empirical applications regarding a training program evaluation and maternity leave reform.

description: Recent study (Yuan et. al., Phys. Rev. B 102, 014422 (2020)) revealed a SOC-independent spin splitting and spin polarization effect induced by antiferromagnetic ordering which do not necessarily require breaking of inversion symmetry or the presence of SOC, hence can exist even in centrosymmetric, low-Z light element compounds, considerably broadening the material base for spin polarization. In the present work we develop the magnetic symmetry conditions enabling such effect, dividing the 1651 magnetic space groups into 7 different spin splitting prototypes (SST-1 to SST-7). We use the 'Inverse Design' approach of first formulating the target property (here, spin splitting in low-Z compounds not restricted to low symmetry structures), then derive the enabling physical design principles to search realizable compounds that satisfy these a priori design principles. This process uncovers 422 magnetic space groups (160 centrosymmetric and 262 non-centrosymmetric) that could hold AFM-induced, SOC-independent spin splitting and spin polarization. We then search for stable compounds following such enabling symmetries. We investigate the electronic and spin structures of some selected prototype compounds by density functional theory (DFT) and find spin textures that are different than the traditional Rashba-Dresselhaus patterns. We provide the DFT results for all antiferromagnetic spin splitting prototypes (SST-1 to SST-4) and concentrate on revealing of the AFM-induced spin splitting prototype (SST-4). The symmetry design principles along with their transformation into an Inverse Design material search approach and DFT verification could open the way to their experimental examination.M).

We discuss a brane-world model with a bulk scalar field, motivated by supergravity. The low-energy effective action is derived and physical constraints on the parameters of the model discussed. The cosmological evolution of the brane-world moduli is investigated and it is shown that one of the moduli is a quintessence field. The CMB predictions are computed. Finally, the possibility that the radion field in brane-worlds could be a chameleon field is investigated.

description: This article presents an overview of results pertaining to electronic structure, transport properties, and interaction effects in ballistic quantum wires with Rashba spin splitting. Limits of weak and strong spin--orbit coupling are distinguished, and spin properties of the electronic states elucidated. The case of strong Rashba spin splitting where the spin--precession length is comparable to the wire width turns out to be particularly interesting. Hybridization of spin--split quantum--wire subbands leads to an unusual spin structure where the direction of motion for electrons can fix their spin state. This peculiar property has important ramifications for linear transport in the quantum wire, giving rise to spin accumulation without magnetic fields or ferromagnetic contacts. A description for interacting Rashba--split quantum wires is developed, which is based on a generalization of the Tomonaga--Luttinger model.

description: We show that Google search activity on relevant terms is a strong out-of-sample predictor for future employment growth in the United States over the period 2004–2019 at both short and long horizons. Starting from an initial search term “jobs,” we construct a large panel of 172 variables using Google’s own algorithms to find semantically related search queries. The best Google Trends model achieves an out-of-sample R2 between 29% and 62% at horizons spanning from one month to one year ahead, strongly outperforming benchmarks based on a single search query or a large set of macroeconomic, financial, and sentiment predictors. This strong predictability is due to heterogeneity in search terms and extends to industry-level and state-level employment growth using state-level specific search activity. Encompassing tests indicate that when the Google Trends panel is exploited using a nonlinear model, it fully encompasses the macroeconomic forecasts and provides significant information in excess of those.

A theoretical framework was constructed to explain the development of CCFG. We find that CCFG was originate from economic growth and will fulfill its goal by economic growth as it closely linked with rural poverty; Constrains such as income decline will finally be solved along with policy adjustment and economic growth; Huge amount of subsidies had been successfully delivered to farmers under strong administration and innovative policy; due to incentive incompatibility between farmers’ private interests and public benefit, we assume that CCFG only achieved second best ecological goals, but a better sustainability. The policy still faces many uncertainties due to climate change, rural development progress, et al.

description: A rigorous theoretical investigation is made of arbitrary amplitude nucleus acoustic solitary waves (SWs) in a fully ionized multi-nucleus plasma system (consisting of thermally degenerate electron species and non-degenerate warm light as well as heavy nucleus species). The pseudo-potential approach, which is valid for the arbitrary amplitude SWs, is employed. The subsonic and supersonic nucleus-acoustic SWs (which are found to be compressive) along with their basic features are identified. The basic properties of these subsonic and supersonic nucleus-acoustic SWs are found to be significantly modified by the effects of non and ultra-relativistically degenerate electron species, dynamics of heavy nucleus species, number densities as well as adiabatic temperatures of light and heavy nucleus species, etc. It shown that the presence of heavy nucleus species with non-degenerate (isothermal) electron species supports the existence of subsonic nucleus-acoustic SWs, and that the effects of electron degeneracies and light and heavy nucleus temperatures reduce the possibility for the formation of these subsonic nucleus-acoustic SWs. The amplitude of the supersonic nucleus-acoustic SWs in the situation of non-relativistically degenerate electron species is much smaller than that of ultra-relativistically degenerate electron species, but is much larger than that of isothermal electron species. The rise of adiabatic temperature of light or heavy nucleus species causes to decrease (increase) the amplitude (width) of the subsonic and supersonic nucleus acoustic SWs. On the other hand, the increase in the number density of light or heavy nucleus species causes to increase (decrease) the amplitude (width) of the subsonic and supersonic nucleus acoustic SWs. The results of this investigation are found to be applicable in laboratory, space, and astrophysical plasma systems.

description: This study examined changes in agricultural productivity at Benin in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA).A time series data which consists of information on agricultural production and means of production were obtained from World Research Institute database, INSAE and rainfall data from AMMA database. The information was for a 43-year period (1961-2003); DEA method was used to measure Malquist index of total factor productivity to evaluate technical change efficiency and technological efficiency change across the country’s 12 provinces. A decomposition of TFP measures revealed whether the performance of factors productivity is due to technological change or technical efficiency change over the reference period. The study further examined the effect of land quality, agriculture labor, and selected governance indicators such as government effectiveness and openness on productivity growth. All the variables included in the model are significant effect on the TPF and the country agriculture growth. They equally performed well in terms of expected relationship with TFP except land quality index which unexpectedly had an inverse relationship with TFP.

description: We study the zero temperature static properties of dissipative ensembles of quantum Ising spins arranged on periodic one dimensional finite clusters and on an infinite chain. The spins interact ferro-magnetically with nearest-neighbour pure and random couplings. They are subject to a transverse field and coupled to an Ohmic bath of quantum harmonic oscillators. We analyze the coupled system using Monte Carlo simulations of the classical two-dimensional counterpart model. The coupling to the bath enhances the extent of the ordered phase, as found in mean-field spin-glasses. In the case of finite clusters we show that a generalization of the Caldeira-Leggett localization transition exists. In the case of the infinite random chain we study the effect of dissipation on the transition and the Griffiths phase.

From roadblocks to traffic jams : a history of three regional libraries in Saskatchewan
Creators: name: Fox, Ken
Publisher: name: University of British Columbia
Year: 2009

description: Although there was no widespread argument against regional libraries in Saskatchewan, broader political obstacles forced a widespread campaign at local levels, carried out by hundreds of volunteers across the province, guided by a small number of professional librarians, and relentlessly supplemented by a provincial lobby consisting of librarians and trustees. The study finds that there are two distinct strategies used by library advocates in promoting regional libraries. A principal conclusion is that the present regional library system was not the result of government initiative, but of public demand. While the CCF governments between 1944 and 1964 created the infrastructure that enabled regional libraries to exist, the Liberal Government responded to the public lobby in providing the key funding increases that led to the establishment of a province-wide regional library network. This study is derived from and based on primary materials, foremost among them the regional library collections owned by the Saskatchewan Archives Board. I have also used secondary materials to illuminate primary sources.

description: Lipid membranes in a physiological context cannot be understood without taking into account their mobile environment. Here, we report on a high energy-resolution neutron backscattering study to investigate slow motions on nanosecond time scales in highly oriented solid supported phospholipid bilayers of the model system DMPC -d54 (deuterated 1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine). This technique allows discriminating the Q-dependent onset of mobility and provides a benchmark test regarding the feasibility of dynamical neutron scattering investigations on these sample systems. Apart from freezing of the lipid acyl-chains, we could observe a second freezing temperature that we attribute to the hydration water in between the membrane stacks. The freezing is lowered several degrees as compared to (heavy) bulk water.

description: We consider a unitary transformation which maps any given state of an $n$-qubit quantum register into another one. This transformation has applications in the initialization of a quantum computer, and also in some quantum algorithms. Employing uniformly controlled rotations, we present a quantum circuit of $2^{n+2}-4n-4$ CNOT gates and $2^{n+2}-5$ one-qubit elementary rotations that effects the state transformation. The complexity of the circuit is noticeably lower than the previously published results. Moreover, we present an analytic expression for the rotation angles needed for the transformation.

A new method for direct rf power absorption studies in CMR materials and high T_c superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The design, fabrication and performance of an apparatus for the measurement of direct rf power absorption in colossal magnetoresistive (CMR) and superconducting samples are described. The system consists of a self-resonant LC tank circuit of an oscillator driven by a NOT logic gate. The samples under investigation are placed in the core of the coil forming the inductance L and the absorbed power is determined from the measured change in the current supplied to the oscillator circuit. A customized low temperature insert is used to integrate the experiment with a commercial Oxford Instruments cryostat and temperature controller. The oscillator working in the rf range between 1 MHz to 25 MHz is built around an IC 74LS04. The temperature can be varied from 4.2 to 400 K and the magnetic field from 0 to 1.4 T. The apparatus is capable of measuring direct power absorption in CMR and superconducting samples of volume as small as 1/1000 cm^3 with a signal to noise ratio of 10:1. Further increase in the sensitivity can be obtained by summing the results of repeated measurements obtained at a given temperature. The system performance is evaluated by measuring the absorbed power in La_0.7 Sr_0.3 MnO_3 (LSMO) CMR manganite samples and superconducting Y Ba_2 Cu_3 O_7 (YBCO) samples at different rf frequencies. All operations during the measurements are automated using a computer with a menu-driven software system, user input being required only for the initiation of the measurement sequence.

description: The main-sequence mercury-manganese (HgMn) stars are known to exhibit large overabundances of exotic elements and, similar to magnetic Ap/Bp stars, are spectrum variables, implying the presence of an inhomogeneous element distribution over the stellar surface. A number of magnetic field studies have been attempted in the last decades, indicating that magnetic fields in HgMn stars, if they exist, should be rather weak. The presence of tangled magnetic fields was suggested by several authors who detected quadratic magnetic fields using the moment technique. We employ the least-squares deconvolution technique to carry out a sensitive search for weak magnetic fields in spectropolarimetric observations of three HgMn stars, HD221507, HD65949, and HD101189, which have different fundamental parameters and spectral characteristics. A definite weak longitudinal field is discovered in HD221507 and HD65949 on single epochs, while only marginal field detections were achieved for HD101189. The new measurements indicate that the structure of the magnetic fields is probably rather complex: our analysis reveals the presence of reversed Stokes V profiles at the same observational epoch if individual elements are used in the measurements. This is the first observational evidence that individual elements sample distinct local magnetic fields of different polarity across the stellar surface.

URBAN WATER RESTRICTIONS: ACCOUNTING FOR BEHAVIOURAL DIFFERENCES

description: Notwithstanding the neoclassical predilection for markets as a means of allocating scarce resources, it remains the case that state-devised attenuation of behaviour is the norm for many resource allocation decisions. This is particularly apparent in the case of water in urban areas in Australia, where mandated water restrictions limit the forms of water use that are permissible. Whilst there has been much debate about the efficacy of this approach, an important underlying question relates to the motivations for individuals to comply. More specifically, if a restriction regime is broadly in line with underlying motivations then, prima facie, it will generate less severe welfare losses than one which is largely at odds with individual drivers of behaviour.

description: As the demand for organic and natural food grows in the U.S., studies show that consumers would and do pay more for these foods than their traditional counterparts. However, the question remains as to whether consumers really understand the differences between organic and natural products versus common products. The USDA provides an official definition of organic, but there is no official definition or certification for natural products. The general lack of knowledge among consumers concerning organic and natural products can be misleading and hence, there is a need for a better understanding of how consumer pre-existing knowledge and new information regarding organic and natural products influences consumer purchasing behavior. In this study, we research the effect of providing consumers with information regarding organic and natural production processes in four separate stages on their willingness to pay (WTP) for various natural/organic meat products. Through the use of survey data collected in-person during the fall of 2007 Nevada, in which 597 surveys were completed, we examine the impact of consumer perceived knowledge of organic and natural grass-fed production processes on their WTP, whether or not new information/knowledge will modify their WTP, and the degree of modification across meat types and cuts. Meats examined vary from high-end to low-end cuts and across various meat types, such as pork and beef. The modeling will include a multinomial probit model to measure WTP and also consider the modeling issues that arise when updated preferences are included. The results of this study will be important for researchers looking to model updated consumer preferences. The purpose of our research is twofold. First, we wish to observe whether or not advertising and other promotional methods truly influence consumer demand and willingness to pay for these specialty meat products. These results will likely be important to the role of marketing and the way in which information is provided to consumers on organic and natural production methods and the potential positive effects of those methods. Additionally, the paper will show how consumers purchasing experiences and pre-existing knowledge might influence their reaction to the same information.
Third generation sfermions decays into Z and W gauge bosons: full one-loop analysis

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The complete one-loop radiative corrections to third generation scalar fermions into gauge bosons Z and W^\pm is considered. We focus on \wt{f}_2 \to Z \wt{f}_1 and \wt{f}_i \to W^\pm \wt{f'}_j (f,f'=t,b). We include both SUSY-QCD, QED and full electroweak corrections. It is found that the electroweak corrections can be of the same order as the SUSY-QCD corrections. The two sets of corrections interfere destructively in some region of parameter space. The full one loop correction can reach 10% in some SUGRA scenario, while in model independent analysis like general MSSM, the one loop correction can reach 20% for large \tanβand large trilinear soft breaking terms A_b.
