description: We present observations of the unusual microlensing event OGLE 2003-BLG-235/MOA 2003-BLG-53. In this event a short duration (~7 days) low amplitude deviation in the light curve due a single lens profile was observed in both the MOA and OGLE survey observations. We find that the observed features of the light curve can only be reproduced using a binary microlensing model with an extreme (planetary) mass ratio of 0.0039 +/- (11, 07) for the lensing system. If the lens system comprises a main sequence primary, we infer that the secondary is a planet of about 1.5 Jupiter masses with an orbital radius of ~3 AU.

description: We present a theory of laterally coupled quantum Hall droplets with electron numbers (N1,N2) at filling factor $ν=2$. We show that the edge states of each droplet are tunnel coupled and form a two-level artificial molecule. By populating the edge states with one electron each a two electron molecule is formed. We predict the singlet-triplet transitions of the effective two-electron molecule as a function of the magnetic field, the number of electrons, and confining potential using the configuration interaction method (CI) coupled with the unrestricted Hartree-Fock (URHF) basis. In addition to the singlet-triplet transitions of a 2 electron molecule involving edge states, triplet transitions involving transfer of electrons to the center of individual dots exist for $(N1 \geq 5, N2 \geq 5)$.

description: We report results from Monte Carlo simulations of the two- and three-dimensional gauge glass at low temperature using parallel tempering Monte Carlo. In two dimensions, we find strong evidence for a zero-temperature transition. By means of finite-size scaling, we determine the stiffness exponent theta = -0.39 +/- 0.03. In three dimensions, where a finite-temperature transition is well established, we find theta = 0.27 +/- 0.01, compatible with recent results from domain-wall renormalization group studies.

ISOPHOT 95 micron observations in the Lockman Hole - The catalogue and an assessment of the source counts

description: We report results from a new analysis of a deep 95 micron imaging survey with ISOPHOT on board the Infrared Space Observatory, over a ~1 square degree area within the Lockman Hole, which extends the statistics of our previous study (Rodighiero et al. 2003). Within the survey area we detect sixty-four sources with S/N>3 (roughly corresponding to a flux limit of 16 mJy). Extensive simulations indicate that the sample is almost complete at fluxes > 100 mJy, while the incompleteness can be quantified down to ~30 mJy. The 95 micron galaxy counts reveal a steep slope below 100 mJy (alpha~1.6), in excess of that expected for a non-evolving source population. In agreement with counts data from ISO at 15 and 175 micron, this favours a model where the IR populations evolve both in number and luminosity densities. We finally comment on some differences found with other ISO results in this area.

description: We show that the Goedel solution of five-dimensional gauged supergravity contains either closed time-like curves through every space-time point or none at all, dependent on the rotational parameter. In addition, we present a deformation of that solution with a parameter kappa which characterizes the symmetry of four-dimensional base space: for kappa = 1, 0, -1 it has spherical, flat and hyperbolic symmetry, respectively. Also investigated are the causal properties of the lifted solution in 10 dimensions.

Factors associated with awareness and utilisation of a community mobilisation intervention for female sex workers in Andhra Pradesh, India
Creators: name: Blankenship, Kim

Publisher: name: American University
Year: 2023

description: Objectives Examine factors associated with awareness and active utilisation of a community mobilisation intervention (CMI) to address HIV risk in female sex workers (FSWs) in a context characterised by multiple forms of sex work. Design Data came from two rounds, conducted in Spring 2006 and Spring 2007, of a serial cross-sectional survey of FSWs (n¼812 in round 1, n¼673 in round 2) recruited through respondent-driven sampling in Rajahmundry, Andhra Pradesh, India. Methods Descriptive statistics compared characteristics of programme aware and unaware FSWs and from among the aware, to characterise active program users. Multinomial logistic regression was used to assess factors associated with programme exposure. Results Between Rounds 1 and 2, programme awareness increased from 41.8% to 69.6% of respondents, and active utilisation (among those who were aware) increased from 49.2% to 61.0%. Streetbased FSWs were under-represented and brothel-based FSWs overrepresented in both groups and rounds. Geographic proximity and literacy were associated with programme awareness but not utilisation. The most important factor associated with both forms of intervention exposure across rounds was willingness to be identified in public as a FSWs (OR 2.2e4.8). Conclusion Public visibility is a critical component of CMIs. Such interventions should develop strategies for involving FSWs that allow them to remain invisible, while also working to reduce the threat associated with public visibility. In contexts where sex work occurs in multiple venues, it is important to develop CMIs that include and address the needs of FSWs working in them all.

description: Findings from female sex workers in southern India indicate that women who enter sex work via trafficking are exposed to unique HIV vulnerabilities. Objectives—To estimate the prevalence of sex trafficking as a mode of entry into sex work, and to examine associations between sex trafficking and recent violence experiences and HIV vulnerability among female sex workers (FSWs). Methods—In a cross-sectional study in 2006 in coastal Andhra Pradesh, India, 812 FSWs were recruited via respondent-driven sampling to take part in an oral survey of their experiences in sex work. Results—One in 5 (19.3%) FSWs met the UN definition of sex trafficking. Women trafficked into sex work were more likely than other FSWs to report recent violence experiences (adjusted odds ratio [AOR], 1.93; 95% confidence interval [CI], 1.32–2.81), more clients per week (AOR, 1.63; 95% CI, 1.11–2.41), and more days of sex work per week (AOR, 1.76; 95% CI, 1.18–2.63), and were less likely to report use of FSW-focused services (AOR, 0.60; 95% CI, 0.42–0.86). No significant differences emerged regarding HIV knowledge or consistent condom use. Conclusion—There was a high prevalence of sex trafficking. A history of sex trafficking was associated with a greater vulnerability to recent violence and HIV risk behaviors, underscoring the need for increased attention to the public health needs of trafficked populations.

description: Researchers increasingly argue that poverty and gender inequality exacerbate the spread of HIV/AIDS and that economic empowerment can therefore assist in the prevention and mitigation of the disease, particularly for women. This paper critically evaluates such claims. First, we examine the promises and limits of integrated HIV/ AIDS prevention and microfinance programs by examining the available evidence base. We then propose future research agendas and next steps that may help to clear current ambiguities about the potential for economic programs to contribute to HIV/AIDS risk reduction efforts.

description: Objective The study assessed non-barrier contraceptive use among female sex workers (FSW) in Andhra Pradesh, India and relation to inconsistent condom use among commercial and non-commercial male sexual partners. Methods FSW at least 18 years of age (n=2338) were recruited through respondent-driven sampling for an HIV risk survey. Analysis was restricted to women of childbearing age (n=2197). Crude and adjusted logistic regression models were used to assess non-barrier contraceptive use and relation to inconsistent condom use with husbands or regular male partners (i.e. non-clients), regular clients and occasional clients. Results Non-barrier methods of contraception included contraceptive pills (3.8%) and sterilisation (68.4%). In logistic regression models adjusted for relevant demographics, FSW using contraceptive pills were more likely to report inconsistent condom use with a regular client (past week) [adjusted odds ratio (AOR) 2.2, 95% confidence interval (CI) 1.2–4.0] and with an occasional client (past week) (AOR 2.6, 95% CI 1.6–5.3), as well as accepting more money for sex without a condom (past 30 days) (AOR 2.5, 95% CI 1.5–4.3). No significant associations were found between pill use and inconsistent condom use among women’s non-client partners, potentially related to small sample sizes within these subgroups. Reporting sterilisation, which was more common among FSW who were older in age, was not associated with inconsistent condom use with client or non-client sexual partners. Conclusions Findings document potential unmet need for modern, spacing contraceptives (i.e. pill, intrauterine device), but also indicate the importance for family planning services, particularly those promoting modern contraceptive methods to be provided alongside HIV prevention among FSW in Andhra Pradesh, India.

description: Purpose: Generalized linear mixed-model (GLMM) and Bayesian methods together provide a framework capable of handling a wide variety of complex data commonly encountered across the communication sciences. Using language sample analysis, we demonstrate the utility of these methods in answering specific questions regarding the differences between discourse patterns of children who have experienced a traumatic brain injury (TBI), as compared to those with typical development.Method: Language samples were collected from 55 adolescents ages 13–18 years, five of whom had experienced a TBI. We describe parameters relating to the productivity, syntactic complexity, and lexical diversity of language samples. A Bayesian GLMM is developed for each parameter of interest, relating these parameters to age, sex, prior history (TBI or typical development), and socioeconomic status, as well as the type of discourse sample (compare–contrast, cause–effect, or narrative). Statistical models are thoroughly described.Results: Comparing the discourse of adolescents with TBI to those with typical development, substantial differences are detected in productivity and lexical diversity, while differences in syntactic complexity are more moderate. Female adolescents exhibited greater syntactic complexity, while male adolescents exhibited greater productivity and lexical diversity. Generally, our models suggest more advanced discourse among adolescents who are older or who have indicators of higher socioeconomic status. Differences relating to lecture type were also detected.Conclusions: Bayesian and GLMM methods yield more informative and intuitive results than traditional statistical analyses, with a greater degree of confidence in model assumptions. We recommend that these methods be used more widely in language sample analysis.

Peer outreach work as economic activity : Implications for HIV prevention interventions among female sex workers
Creators: name: George, Annie
name: Blankenship, Kim
Publisher: name: American University
Year: 2023

description: Female sex workers (FSWs) who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers’ economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers’ relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

description: We report results demonstrating a singularity in the hysteresis of magnetic materials, the reversal-field memory effect. This effect creates a nonanalyticity in the magnetization curves at a particular point related to the history of the sample. The microscopic origin of the effect is associated with a local spin-reversal symmetry of the underlying Hamiltonian. We show that the presence or absence of reversal-field memory distinguishes two widely studied models of spin glasses (random magnets).

description: As a working team, our group collectively assessed the sustainability of the UBC food system and identified the ways in which the UBC South Campus Farm (UBC Farm) can contribute to a sustainable food system. Specifically, we have examined the potential of the UBC Farm to supply healthy, diverse food products to various local UBC outlets. Through interviews we discovered that the productive capacity of the farm can be increased to meet growing demand for local foods, either through small-scale animal systems, greenhouse production, or expanding the UBC Market Garden project. The barriers which hinder these expansions were also identified, and include the following: degraded or missing infrastructure, government regulations concerning meat production, and limited market opportunities for non-processed food. This document also serves as a “stepping stone” for future students to use by identifying areas for future research. Future students should examine the possibility of processing food from UBC Farm, labeling the food as locally or organically grown, incorporating wetland and forested areas in agriculture production, and methods of integrating animals back onto the farm. By examining where the “holes” (or weaknesses) in the current food system lie, our group envisioned the ways in which the UBC Farm could fill these “holes” and fulfill our utopian view of a sustainable food system.

title: Exploring sources of competitive advantage in e-business applications: A cross-industries case study in mainland China
Creators: name: Tao, Yan
Publisher: name: The Open University
Year: 2011

description: A review of existing literature revealed that little theoretical framework exists to capture e-business-enabled value creation through an integrated approach that includes the environmental view and resource-based view (RBV). Furthermore, little empirical research has been conducted to test these theoretical frameworks, in particular in the Chinese business context. The aim of this research is to extend the theoretical and practical understanding of e-business-enabled sources of competitive advantage (SCA) in China. The value chain (VC) concept, virtual value chain (VVC) framework and RBV were identified from the literature as the key constructs to underpin the theoretical basis. The research design used a qualitative research methodology consisting of indepth case studies of nine leading Chinese companies in three industries - housing development, manufacturing, and B2C. The principle finding is the formulation of a theoretical framework for investigating ebusiness value creations which integrates the key constructs of the VVC, online information capabilities (OIC), value system and RVB. This research also proposes a typology of five generic types of key e-business applications which states clearly the relationships between key e-business applications and SCA. Finally, this research demonstrates that e-business value creation features differently between two groups: Internet pragmatist and Internet pioneers. The research offers a number of contributions to the field of e-business value creation. Firstly, it introduces the concepts of OIC and value system to the VVC. It also provides empirical test of the analytical framework. In addition, this research provides an indepth understanding of the relationships between types of e-business applications and key SCA. Finally, this research identifies and explains the key differences and similarities between the three industries, within each industry, and between the two key groups.

description: We show that in low dimensional disordered conductors, the quasiparticle decay and the relaxation of the phase are not exponential processes. In the quasi-one dimensional case, both behave at small time as $e^{- (t/τ_{in})^{3/2}}$ where the inelastic time $τ_{in}$, identical for both processes, is a power $T^{2/3}$ of the temperature. This result implies the existence of an unusual distribution of relaxation times that we obtain.

We conclude that the uncertainty on the isospin-breaking correction which must be applied to the tau decay data should be significantly increased, and that the central value of the rho-omega ``mixing'' contribution to this correction may be significantly smaller than indicated by the present standard determination. Such a shift would contribute to reducing the discrepancy between the tau- and electroproduction-based determinations of the leading order hadronic contribution to a_mu.

FAIR-EASE - D6.3 - First report on users engagement
Creators: name: LEFEVRE, Corentin
Publisher: name: Zenodo
Year: 2024

description: This report presents an analysis of user engagement within FAIR-EASE. The project was designed from the outset to foster strong user engagement, for which a variety of activities have been carried out in a transversal manner, ensuring that all aspects of the project benefit from users’ input and interaction.

At the mid-term stage of the project, the main focus was put towards engaging users within the consortium itself, in particular through a constant mobilisation of the scientific communities involved in FAIR-EASE use cases and pilots.

In addition to this internal focus, efforts have also been made to disseminate information beyond the boundaries of the consortium. This outward-facing strategy has been successful in raising awareness of the project and its objectives among a wider audience.

The success of these strategies is evident in the high levels of user engagement and the feedback received. As the project moves forward, efforts will be put into reaching outside communities based on the expected results. This will ensure that the benefits of the project are shared as widely as possible, thereby maximizing its impact.

description: Precise Li abundances are determined for 54 giant stars mostly evolving across the Hertzsprung gap. We combine these data with rotational velocity and with information related to the deepening of the convective zone of the stars to analyse their link to Li dilution in the referred spectral region. A sudden decline in Li abundance paralleling the one already established in rotation is quite clear. Following similar results for other stellar luminosity classes and spectral regions, there is no linear relation between Li abundance and rotation, in spite of the fact that most of the fast rotators present high Li content. The effects of convection in driving the Li dilution is also quite clear. Stars with high Li content are mostly those with an undeveloped convective zone, whereas stars with a developed convective zone present clear sign of Li dilution.

description: Background—Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted infection (STI) that is the main cause of genital herpes. Studies have found racial/ethnic disparities in HSV-2 prevalence, but there have been few studies of racial/ethnic differences in the proportion of infections that go without a genital herpes diagnosis. Methods—Data from 1396 HSV-2-seropositive participants of the National Health and Nutrition Examination Survey 1999–2004 were used to examine racial/ethnic differences in the odds of reporting being diagnosed previously with genital herpes. Results—The proportion of participants who reported not being diagnosed previously with genital herpes was 85.5%. In adjusted analysis, non-Hispanic blacks had twice the odds of reporting being undiagnosed as non-Hispanic whites (adjusted odds ratio = 2.0, 95% CI = 1.37, 2.87). Being undiagnosed was also significantly associated with less than high school education, no prior STI history or HIV test, no current health insurance, and residence in the Midwest and South. Conclusions—The low proportion of genital herpes diagnosis among non-Hispanic blacks with HSV-2 is not accounted for by other socio-demographic factors or health insurance. Combined with the high prevalence of HSV-2, the low proportion of diagnosis in this population is more likely to contribute to ongoing HSV-2 transmission than among non-Hispanic whites or Mexican Americans. More research is needed to assess the role that lack of diagnosis plays in ongoing HSV-2 transmission, and whether targeted HSV-2 screening, counseling

description: The ORPHEUS dark matter detector is operating at our underground laboratory in Bern (70 m.w.e.). The detector relies on measuring the magnetic flux variation produced by weakly interacting massive particles (WIMPs) as they heat micron-sized superheated superconducting tin granules (SSG) and induce superconducting-to-normal phase transitions. In an initial phase, 0.45 kg of tin granules in a segmented detector volume have been used. In this paper a general description of the experimental set-up, overall performance of the detector, and first results are presented.

description: Structural interventions refer to public health interventions that promote health by altering the structural context within which health is produced and reproduced. They draw on concepts from multiple disciplines, including public health, psychiatry, and psychology, in which attention to interventions is common, and sociology and political economy, where structure is a familiar, if contested, concept. This has meant that even as discussions of structural interventions bring together researchers from various fields, they can get stalled in debates over definitions. In this paper, we seek to move these discussions forward by highlighting a number of critical issues raised by structural interventions, and the subsequent implications of these for research.

description: The H atoms inside minihalos (i.e. halos with virial temperatures T_vir < 10^4 K, in the mass range roughly from 10^4 M_sun to 10^8 M_sun) during the cosmic dark ages in a LCDM universe produce a redshifted background of collisionally-pumped 21-cm line radiation which can be seen in emission relative to the cosmic microwave background (CMB). Previously, we used semi-analytical calculations of the 21-cm signal from individual halos of different mass and redshift and the evolving mass function of minihalos to predict the mean brightness temperature of this 21-cm background and its angular fluctuations. Here we use high-resolution cosmological N-body and hydrodynamic simulations of structure formation at high redshift (z > 8) to compute the mean brightness temperature of this background from both minihalos and the intergalactic medium (IGM) prior to the onset of Ly-alpha radiative pumping. We find that the 21-cm signal from gas in collapsed, virialized minihalos dominates over that from the diffuse shocked gas in the IGM.

Theory of the anomalous spin dynamics of spin-$\frac{1}{2}$ triangular lattice Heisenberg antiferromagnet and its application to Ba$_3$CoSb$_2$O$_9$

description: Although it is well accepted that the spin-$\frac{1}{2}$ triangular lattice Heisenberg antiferromagnet(TLHAF) has a long range ordered ground state, a thorough understanding of its spin dynamics is still missing. While the linear spin wave theory(LSWT) predicts three branches of magnon mode in the magnetic Brillouin zone(MBZ), the 1/S expansion at the next order is found to break down in a large portion of the MBZ centered around the M point, leaving the fate of the magnon modes there undecided. Recent neutron scattering measurement on Ba$_3$CoSb$_2$O$_9$, an ideal realization of the spin-$\frac{1}{2}$ TLHAF, provides a surprising answer to this issue. Two, rather than three branches of magnon mode are observed around the M point, whose dispersion are strongly renormalized with respect to the LSWT prediction and exhibit pronounced roton-like minimum at the M point. This is accompanied by a strong spin fluctuation continuum at higher energy, inside which two strong and broad spectral peaks of unknown origin are observed. In this work, we propose a simple picture for these spectral anomalies by invoking the resonating valence bond(RVB) physics in the description of the ground state of the system. We find that the roton-like minimum in the magnon dispersion can be explained by the coupling between the collective spin fluctuation and the continuum of Dirac spinon excitation moving in a $π$-flux background. We also propose that the two broad peaks in the continuum can be understood respectively as the Landau damped third magnon mode and the Landau damped longitudinal mode. Such a picture can be verified by studying the polarization character of the various spectral features.

description: Double-exchange model interacting with adiabatic phonons is studied in the presence of randomness by using the Monte-Carlo method and the systematic size-scaling analysis. A bicritical behavior is found between the ferromagnetic metal and the charge-ordered insulator. We find the distinct response to the randomness between these two states, which agrees well with the experimental results in the colossal magnetoresistance manganites.
