description: Background: Same-day initiation (SDI) of antiretroviral therapy (ART) has been advocated as an approach to increase linkage to care and overall ART initiation. Clinical trials have demonstrated impressive benefits. However, questions regarding patient preparedness and retention in care remain for routine implementation of this approach. Objectives: In this study, we sought to describe SDI of ART during routine care delivery and compare time to ART initiation on longitudinal care outcomes. Method: We performed a retrospective chart review of 100 consecutive individuals, newly diagnosed with HIV, from 10 health facilities across Ekurhuleni, from January to July 2017. Records were reviewed for a period of 1 year post-diagnosis. Abstracted data included demographics, time to ART initiation, clinic visits and laboratory test results (including viral load testing). Results: A total of 993 patient records were reviewed, of which 826 were included in the analysis. The majority of patients (752, 91%) had ART initiation recorded, of which 654 (79%) had ART initiated within 30 days, and 224 (27%) had SDI. Uptake of SDI of ART was higher among women (36% vs. 10.4%; p < 0.001) and in younger patients (33.7% in those < 29 years; p < 0.01). Retention in care at 6 months was achieved in 477 (58%) patients. Of those with 6-month viral loads, 350/430 (73%) had a viral load < 400 c/m. Retention in care and viral suppression were similar among those with SDI of ART and later ART initiation. Conclusion: Same-day initiation of ART was successfully delivered with similar retention and viral load outcomes as subsequent initiation, providing re-assurance for scale-up of this strategy in routine care.

description: We analyze spectral functions of mesoscopic systems with large dimensionless conductance, which can be described by a universal Hamiltonian. We show that an important class of spectral functions are dominated by one single state only, which implies the existence of well-defined (i.e. infinite-lifetime) quasiparticles. Furthermore, the dominance of a single state enables us to calculate zero-temperature spectral functions with high accuracy using the density-matrix renormalization group. We illustrate the use of this method by calculating the tunneling density of states of metallic grains and the magnetic response of mesoscopic rings.

description: We present a new Matlab toolbox for generating phase and amplitude patterns for digital micro-mirror device (DMD) and liquid crystal (LC) based spatial light modulators (SLMs). This toolbox consists of a collection of algorithms commonly used for generating patterns for these devices with a focus on optical tweezers beam shaping applications. In addition to the algorithms provided, we have put together a range of user interfaces for simplifying the use of these patterns. The toolbox currently has functionality to generate patterns which can be saved as a image or displayed on a device/screen using the supplied interface. We have only implemented interfaces for the devices our group currently uses but we believe that extending the code we provide to other devices should be fairly straightforward. The range of algorithms included in the toolbox is not exhaustive. However, by making the toolbox open sources and available on GitHub we hope that other researchers working with these devices will contribute their patterns/algorithms to the toolbox.

title: Plant morphogenesis and genetic transformation of horticultural brassicas
Creators: name: Sparrow, Penelope Amelia Claire
Publisher: name: The Open University
Year: 2003

description: This study set out to elucidate the genetic control of in vitro shoot morphogenesis and the production of transgenic plants in horticultural brassicas. Desirable characteristics associated with successful transformation were identified. These include susceptibility to A. tumefaciens, high shoot regeneration potential and the production of multiple shoots in association with a distinct swelling or callus phase. Diallel analysis showed that both high and multiple shoot regeneration are heritable traits, with additive gene effects accounting for 71 % and 77 % of the genetic variation respectively. High susceptibility to A. tumefaciens was shown to have a positive effect on transformation efficiency. A highly significant putative QTL associated with susceptibility to A. tumefaciens was located on linkage group 09 of B. oleracea, and substitution lines confirmed the presence of this QTL. Additive gene effects also accounted for 79 % of the genetic control of susceptibility to A. tumefaciens. The ability to increase both in vitro shoot regeneration potential and susceptibility to A. tumefaciens in subsequent generations, through conventional breeding methods, was successfully demonstrated. Tissue culture blackening was shown to be a critical factor limiting the production of transgenic shoots.

A Brassica oleracea genotype, DH 1012, was identified that produced transgenic shoots at a rate higher than anything previously reported, for the transformation of cotyledonary petioles using A. tumefaciens. The speed and efficiency of regeneration enabled the isolation of transgenic shoots just 4 weeks after inoculation with A. tumefaciens. The efficacy of DH 1012 as a potential model genotype for transformation is demonstrated. A transformation rate of up to 31 % combined with the availability of an associated genetic linkage map will make this genotype very desirable as a potential research and development tool for studying gene function.

description: Using scanning probe microscopy and spectroscopy, we explore the spatial symmetry of the electronic wavefunctions of twisted bilayer graphene at the "magic angle" of 1.1 degrees. This small twist angle leads to a long wavelength moiré unit cell on the order of 13 nm and the appearance of two flat bands. As the twist angle is decreased, correlation effects increase until they are maximized at the magic angle. At this angle, the wavefunctions at the charge neutrality point show only C2 symmetry due to the emergence of a charge ordered state. As the system is doped, the symmetry of the wavefunctions change at each commensurate filling of the moiré unit cell pointing to the correlated nature of the spin and valley degeneracy broken states.

Donors' responses to profit incentives in the social sector : The entrepreneurial orientation reward and the profit penalty

Publisher: name: American University

description: This study uses an online survey experiment to test whether the pairing of profit-seeking with mission-related programs in the social sector attracts or deters donations from individual donors. We test individuals’ response to three types of profit incentives allowed under current U.S. public policy: (1) non-distributed profit to an organization, which is allowed for nonprofit entities; (2) profit to the organization's equity investors and owners, which is allowed under for-profit social enterprise governance charters; and (3) profit to lending investors, which is introduced by social impact bonds, a pay-for-success policy tool. We test trust theory, under which profit incentives deter donors against entrepreneurial orientation (EO) theory, which suggests that donors are attracted to organizations that use innovative, market-driven programs. Findings indicate support for both theories, but the support depends on how the specific profit incentive is structured. Donors support organizations that use profit-generating social enterprise programs—but only when the profits are non-distributable; donors’ support is significantly lower for social enterprises in which owners and equity investors may profit. Importantly however, this negative effect is not found for pay-for-success policy tools where lending investors, rather than equity investors and owners, receive profits.

description: We perform an adjust to the most recent structure function data, considering the QCD dipole picture applied to ep scattering. The structure function F2 at small x and intermediate Q2 can be described by the model containing an economical number of free-parameters, which encodes the hard Pomeron physics. The longitudinal structure function and the gluon distribution are predicted without further adjustments. The data description is effective, whereas a resummed next-to-leading level analysis is deserved.

description: Intra-day price spreads are of interest to electricity traders, storage and electric vehicle operators. This paper formulates dynamic density functions, based upon skewed-t and similar representations, to model and forecast the German electricity price spreads between different hours of the day, as revealed in the day-ahead auctions. The four specifications of the density functions are dynamic and conditional upon exogenous drivers, thereby permitting the location, scale and shape parameters of the densities to respond hourly to such factors as weather and demand forecasts. The best fitting and forecasting specifications for each spread are selected based on the Pinball Loss function, following the closed-form analytical solutions of the cumulative distribution functions.

A Flux-Conservative Formalism for Convective and Dissipative Multi-Fluid Systems, with Application to Newtonian Superfluid Neutron Stars

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

subject: FOS: Physical sciences

description: We develop a flux-conservative formalism for a Newtonian multi-fluid system, including dissipation and entrainment (i.e. allowing the momentum of one fluid to be a linear combination of the velocities of all fluids). Maximum use is made of mass, energy, and linear and angular momentum conservation to specify the equations of motion. Also used extensively are insights gleaned from a convective variational action principle, key being the distinction between each velocity and its canonically conjugate momentum. Dissipation is incorporated to second order in the ``thermodynamic forces'' via the approach pioneered by Onsager. An immediate goal of the investigation is to understand better the number, and form, of independent dissipation terms required for a consistent set of equations of motion in the multi-fluid context. A significant, but seemingly innocuous detail, is that one must be careful to isolate ``forces'' that can be written as total gradients, otherwise errors can be made in relating the net internal force to the net externally applied force. Our long-range aim is to provide a formalism that can be used to model dynamical multi-fluid systems both perturbatively and via fully nonlinear 3D numerical evolutions. To elucidate the formalism we consider the standard model for a heat-conducting, superfluid neutron star, which is believed to be dominated by superfluid neutrons, superconducting protons, and a highly degenerate, ultra-relativistic gas of normal fluid electrons. We determine that in this case there are, in principle, 19 dissipation coefficients in the final set of equations.

The purpose of these observations, carried out with the Giant Metrewave Radio Telescope (GMRT, Pune, India) was to study the radio halo located at the centre of A3562 and determine the shape of its radio spectrum at low frequencies, in order to understand the origin of this source. In the framework of the re--acceleration model, the preliminary analysis of the halo spectrum suggests that we are observing a young source (few $10^8$ yrs) at the beginning of the re--acceleration phase.

description: Vitamin A deficiency is still a challenge in many African countries, including Tanzania. Survey data were gathered in Tanzania to determine consumers’ risk perceptions of vitamin A deficiency (VAD) and severe visual impairment. A contingent valuation method was used and a choice experiment was conducted to measure willingness to pay (WTP) for biofortified rice, both with and without introducing genetic modification as the mechanism behind increased vitamin A content. The results indicate that the most at-risk groups, such as females and those with lower incomes, tend to underestimate the risk of VAD or do not fully understand the relationship between VAD and severe visual impairment. Furthermore, the respondents strongly preferred and were willing to pay for rice with added nutritional value.
Anomaly cancellation in M-theory: a critical review

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We carefully review the basic examples of anomaly cancellation in M-theory: the 5-brane anomalies and the anomalies on S^1/Z_2. This involves cancellation between quantum anomalies and classical inflow from topological terms. To correctly fix all coefficients and signs, proper attention is paid to issues of orientation, chirality and the Euclidean continuation. Independent of the conventions chosen, the Chern-Simons and Green-Schwarz terms must always have the same sign. The reanalysis of the reduction to the heterotic string on S^1/Z_2 yields a surprise: a previously neglected factor forces us to slightly modify the Chern-Simons term, similar to what is needed for cancelling the normal bundle anomaly of the 5-brane. This modification leads to a local cancellation of the anomaly, while maintaining the periodicity on S^1.

description: Using an original database from French archives on French trade statistics, this article undertakes a comprehensive study of the nature and dynamic of French sectoral trade for the period 1880 to 1912. The results highlight a common trend regarding Franco-colonial trade compared to French trade with non-French colonies. In particular, we found that French trade with its colonies was based mainly on imports of primary products and exports of manufactured goods, meaning that the Empire was used as the main dispenser of French exports and the country’s main provider of natural resources. Statistics also emphasise that the event of colonisation was followed by an increase in trade between France and its own colonies, while colonisation by Britain and other colonising countries did not affect trade between France and non-French colonies. The article finally reveals that trade with French colonies was unbalanced and unidirectional, without any advantage in favour of those colonies.

description: The Test of English for International Communication (TOEIC) has been widely used to measure English proficiency over decades. Despite being commonly accepted, there are some controversial issues concerning the correlation between English language ability and TOEIC scores. This paper evaluates the TOEIC Reading section of the TOEIC Listening and Reading test in terms of the four major principles of language assessment: validity, reliability, authenticity, and practicality. The evaluation in this paper is based on the TOEIC Sample test and the TOEIC Examinee Handbook. The evaluation revealed that the TOEIC Reading test shows a certain level of validity and reliability. Moreover, the test is in agreement with authenticity as the language used is natural and somehow related to real-life situations. However, interactiveness and contextualization should be taken into consideration. Additionally, the test has strong practicality due to its sufficient resources used. Finally, some examples of alternative test types are provided.

description: Chiral spin pumping is the generation of a unidirectional spin current in half of ferromagnetic films or conductors by dynamic dipolar stray fields from close-by nanomagnets. We formulate a general theory of long-range chiral interactions between magnets mediated by unidirectional traveling waves, e.g., spin waves in a magnetic film or microwaves in a waveguide. The traveling waves emitted by an excited magnet can be perfectly trapped by a second, initially passive, magnet by a dynamical interference effect. When both magnets are excited by a uniform microwave, the chiral interaction between them creates a large imbalance in their magnon numbers.

publisherIdentifierScheme: ROR
Year: 2001

description: Research has shown that searching for the presence of a feature among featureless distractors is easier than searching for the absence of a feature among distractor objects containing the feature. The present study examined motion perception within this context while manipulating motion type and target density. Further, the element of angular expansion was also included as part of the moving stimuli. Using a standard computer interface, participants were asked to respond as quickly as they could to a variety of moving stimuli. Results showed that it took more time to detect stationary targets among moving distractors than to find moving targets among stationary distractors. Further, adding targets, or changing the type of motion, facilitated detection times within the absence of motion framework whereas adding targets or changing the type of motion within the presence conditions had very little impact. These findings could have important design implications when constructing dynamic displays that require immediate attention to critical information.
Approaches to optimize Uzbekistan's investment in irrigation technologies

Publisher: name: American University

description: For many decades, Uzbekistan has been one of the largest cotton producers in the world. The irrigation water needed for these high production levels has been delivered by the massive diversion of the Amu Darya and Syr Darya rivers, which naturally flowed into the Aral Sea. This diversion for agriculture was the main cause of the rapid decline of the Aral Sea, which is at only 10% of its original size today. The traditional method of irrigation, which relies on simple open canal systems, is highly inefficient for managing the region's critical and limited water resource. It has been qualitatively estimated, for example, that irrigation water lost to evaporation and system inefficiencies is quite large. With the future availability of water at risk for agriculture in Central Asia, primarily due to the loss of glacial volume from global warming, along with declines in seasonal snowpack, it is clear that new approaches to water management are needed. Any serious efforts to restore the Aral Sea and its ecological services would also reduce supplies of irrigation water for Uzbekistan. While regional conflict over water is unlikely, it must be considered since Uzbekistan is a downstream country among several that rely on the Amu Darya and Syr Darya rivers for most of their water supplies. To insure against these risks to cotton production and the underlying economy, better irrigation technologies are needed across Uzbekistan. However, these technologies can be quite expensive, especially given that water is still nearly free. In this case study we explore the use of real options analysis (ROA) to look for optimal investment strategies in efficient irrigation technologies in light of variable climate and policy uncertainties.

description: We present an analytical solution to the dynamics of a noninteracting cloud of thermal atoms in a cigar-shaped harmonic trap with a quartic perturbation along the axial direction. We calculate the first and second moments of position, which are sufficient to characterize the trap. The dynamics of the thermal cloud differ notably from those of a single particle, with an offset to the oscillation frequency that persists even as the oscillation amplitude approaches zero. We also present some numerical results that describe the effects of time-of-flight on the behavior of the cloud in order to better understand the results of a hypothetical experimental realization of this system.

description: The paper analyses economic characteristics of the farms, situated in the less favored areas of Lithuania and Poland. A comparative analysis of farms located in less-favored areas in Lithuania and Poland was conducted in terms of their income diversification and economic situation. In addition, a short description of the compensation payments, their types and rates, was provided in both countries. Using the panel models and correlation analyzes, we identified the most important determinants of agricultural income. The gross agricultural income per hectare of UR was estimated as variable. It was hypothesized that the location of farms in LFA areas determined the income of their owners in a statistically significant way. The impact of compensatory payments on the economic situation of the surveyed companies in Lithuania and Poland was also shown.

description: Supersymmetric Slavnov-Taylor and Ward identities are investigated in presence of soft and spontaneous symmetry breaking. We consider an abelian model where soft supersymmetry breaking yields a mass splitting between electron and selectron and triggers spontaneous symmetry breaking, and we derive corresponding identities that relate the electron and selectron masses with the Yukawa coupling. We demonstrate that the identities are valid in dimensional reduction and invalid in dimensional regularization and compute the necessary symmetry-restoring counterterms.

Social distancing during the COVID-19 pandemic : who are the present and future non-compliers?
Creators: name: Pedersen, Mogens Jin

Publisher: name: American University
Year: 2023

description: Social distancing is an effective means for containing the spread of COVID-19, but only so if we all participate. Who are the individuals who are the least likely to adhere to social distancing recommendations, presently and in the long-term? Such knowledge is important for policymakers looking to sustain the public's buy-in to social distancing. Using survey data from sample U.S. residents (n = 1,449), we show that some demographic factors (gender, age, race, political party) help predict intent to adhere to social distancing. Yet demographic factors are relatively poor predictors compared to individual attitudes and media diets. We argue that public officials should make efforts to inform and persuade the public of the importance of social distancing, targeting mediums like TV and radio where audiences are less likely to currently engage in social distancing or are less likely to envision themselves sustaining strict social distancing for several weeks or months.

description: This study examined the effect of capital investment on the productivity of agricultural sphere of Nigeria. The productivity of the sector was proxy as the agriculture’s contribution to the GDP while commercial bank loan to agriculture, annual budgetary allocation to agricultural sector and various categories of ACGS loan scheme were proxy as investment frameworks. The data used for thus study were extracted from various bulletin of Central Bank of Nigeria and National Bureau of Statistics from 1978–2014. The long and short run relationship of these variables were estimated using the Johansen approach to cointegration and the Vector Autoregressive Error Correction Model respectively. The test of cointegration revealed presence of long run relationship among the various investment sources and categories and agricultural productivity in Nigeria. This confirmed capital as the lubricant of the production process without which other factors of production may become difficult to acquire. The short run estimates revealed total volume of loan, volume of loan to individual and volume of loan above N100,000 as variables that influence agricultural productivity in the short run, further confirming the important place of capital investment in creating jobs in agricultural sector.
Nematic and time-reversal breaking superconductivities coexisting with quadrupole order in a $Γ_3$ system

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

description: We discuss superconductivity in a model on a cubic lattice for a $Γ_3$ non-Kramers system. In previous studies, it is revealed that $d$-wave superconductivity with $E_g$ symmetry occurs in a wide parameter range in a $Γ_3$ system. Such anisotropic superconductivity can break the cubic symmetry of the lattice. In a $Γ_3$ system, the quadrupole degrees of freedom are active and the effect of the cubic symmetry breaking should be important. Here, we investigate the coexisting states of the $d$-wave superconductivity and quadrupole order by a mean-field theory. In particular, we discuss possible competition and cooperation between the superconductivity and quadrupole order depending on types of them. We find nematic superconductivity breaking the cubic symmetry and coexisting with quadrupole order. In the present model, we also find $d+id$ superconductivity, which breaks time-reversal symmetry but retains the cubic symmetry. We also discuss the effects of uniaxial stress on these superconducting states.

description: Currently the state activity in the direction of overcoming the consequences of the disaster significantly decreased, that has deepened economic, social and demographic problems of this region and negatively affected the radioactively contaminated areas rural population living standards indicators. There is an urgent need to study the contaminated areas rural residents level of income, their formation sources and establish the relationship of population living standards with their social status and social benefits. The research is dedicated to major factors of income level formation and employment of the rural population in the radioactive contamination grounding. Significant income stratification of Zhytomyr region rural contaminated areas population was found during the research. It was established that 64.8 % rural population resisting the radioactively contaminated areas live below the poverty line. Radioactively contaminated areas rural resident’s income is formed mainly due to pension payments (57.1 % of respondents’ answers) and wages (41.9 %). A quarter of radioactive contamination areas rural families’ income is received from household grown products sales, 14.3 % – forest origin products. Public sector, forestry and agriculture enterprises are major employers in the radioactive contamination area. A low level of income and high differentiation degree are observed on the territory of rural areas that was affected from radioactive contamination. Rural resident’s self-employment desire and revenues from household production and forest industry significant proportion is the main tendency of revenues formation. High level and duration of unemployment on radioactive contamination rural area is caused by labor market conjuncture violations.
Charged-Particle Pseudorapidity Distributions in Au+Au Collisions at sqrt(s_NN)=62.4 GeV

description: The charged-particle pseudorapidity density for Au+Au collisions at sqrt(s_NN)=62.4 GeV has been measured over a wide range of impact parameters and compared to results obtained at other energies. As a function of collision energy, the pseudorapidity distribution grows systematically both in height and width. The mid-rapidity density is found to grow approximately logarithmically between AGS energies and the top RHIC energy. As a function of centrality, there is an approximate factorization of the centrality dependence of the mid-rapidity yields and the overall multiplicity scale. The new results at sqrt(s_NN)=62.4 GeV confirm the previously observed phenomenon of ``extended longitudinal scaling'' in the pseudorapidity distributions when viewed in the rest frame of one of the colliding nuclei. It is also found that the evolution of the shape of the distribution with centrality is energy independent, when viewed in this reference frame. As a function of centrality, the total charged particle multiplicity scales linearly with the number of participant pairs as it was observed at other energies.

description: Efficient detection of the magnetic state at nanoscale dimensions is an important step to utilize spin logic devices for computing. Magnetoresistance effects have been hitherto used in magnetic state detection, but they suffer from energetically unfavorable scaling and do not generate an electromotive force that can be used to drive a circuit element for logic device applications. Here, we experimentally show that a favorable miniaturization law is possible via the use of spin-Hall detection of the in-plane magnetic state of a magnet. This scaling law allows us to obtain a giant signal by spin Hall effect in CoFe/Pt nanostructures and quantify an effective spin-to-charge conversion rate for the CoFe/Pt system. The spin-to-charge conversion can be described as a current source with an internal resistance, i.e., it generates an electromotive force that can be used to drive computing circuits. We predict that the spin-orbit detection of magnetic states can reach high efficiency at reduced dimensions, paving the way for scalable spin-orbit logic devices and memories.
