description: Some critics, most notably P.D. James, have offered important reflections on Jane Austen's Emma as a precursor to the detective story. Although there is no murder, a mystery and the hermeneutic process of coding/decoding are the narrative engine of Austen’s novel. Its countryside setting, perceived by the modern reader with a nostalgic eye, and its distinctive cast of characters create an anthropic and natural backdrop that reworks the aesthetic category of the picturesque, as in the novel's unforgettable tricolon: ‘English greenery, English culture, English comfort.’ I note a similar aesthetic in several Golden Age crime writers and their contemporary successors, including Caroline Graham. Post-World War I Janeism and the creation of a wistful nostalgia coinciding with the emergence of Agatha Christie's detective worlds respond to the nostalgic longing for an irrecoverable past with their reassuring fictions of order and legibility in the face of epochal paradigm shifts. Jane Austen's Emma thus becomes the figurehead of a cross-temporal, multi-media legacy ranging from William Blake's ‘Jerusalem’ to Midsomer Murders.

description: The investigation of devitrification in thermally annealed nanodimensional glassy alloy thin films provides a comprehensive understanding of their thermal stability, which can be used to explore potential applications. The amorphous to crystalline polymorphous transformation of cosputtered NiZr alloy (Ni78Zr22 at%) films, with a thickness lower than the reported critical limit of devitrification, was studied through detailed structural characterization and molecular dynamics (MD) simulations. Devitrification to a nanocrystalline state (Ni7Zr2 structure) was observed at 800 degC, with an increase in density (approx 3.6%) much higher than that achieved in bulk alloys. Variation in the magnetic property of the films and the overall physical structure including morphology and composition were examined before and after annealing. MD simulations were employed to effectively elucidate not only the high densification but also the increased magnetic moment after annealing, which was correlated with the simulated change in the coordination number around Ni atoms. The structural relaxation process accompanying devitrification was described as a disorder-to-order transformation while highlighting the crucial role played by chemical short range order prevalent in glassy materials.
Neuro-symbolic Systems for Ethical AI: Challenges and Opportunities

description: Machine learning (ML) techniques have become pervasive across a range of different applications, and are now widely used in areas as disparate as recidivism prediction, consumer credit-risk analysis, and insurance pricing. Like- wise, in the physical world, ML models are critical components in autonomous agents such as robotic surgeons and self-driving cars. Among the many ethical dimensions that arise in the use of ML technology in such applications, analyzing morally permissible actions is both immediate and profound. For example, there is the potential for learned algorithms to become biased against certain groups. More generally, in so much that the decisions of ML models impact society, both virtually (e.g., denying a loan) and physically (e.g., driving into a pedestrian), notions of accountability, blame and responsibility need to be carefully considered.

In this talk, we advocate for a two-pronged approach ethical decision-making enabled using rich models of autonomous agency: on the one hand, we need to draw on philosophical notions of such as beliefs, causes, effects and intentions, and on the other, we consider the problem of practical and effective knowledge acquisition and learning.

Towards variance-matrix characterization of complementarity relations in a continuous variable system

description: We discuss complementarity relations in a bipartite continuous variable system. Building up from the work done on discrete d-dimensional systems, we prove that for symmetric two-mode states, quantum complementarity relations can be put in a simple relation with the elements of the variance matrix. When this condition is not satisfied, such a connection becomes non-trivial. Our investigation is the first step towards an operative characterization of the complementarity in a scenario that has not been investigated so far.

description: Motivated by models of holographic technicolor, we discuss a four-site deconstructed Higgsless model with nontrivial wavefunction mixing. We compute the spectrum of the model, the electroweak triple gauge boson vertices, and, for brane-localized fermions, the electroweak parameters to O(M^2_W/M^2_rho). We discuss the conditions under which "S" vanishes (even for brane-localized fermions) and the (distinct but overlapping) conditions under which the phenomenologically interesting decay a_1 to W gamma is non-zero and suppressed by only one power of M_W/M_rho.

A bound-state solution, driven by the Delta(1232) and Sigma(1385) p-wave meson-baryon resonances, was found in the channel (I,JP)=(3/2,2+), provided the Lambda lab momentum at which the Lambda-nucleon S=1,L=0,J=1 phase shift becomes negative is larger than about 750-800 MeV/c. Other strange and charmed pion-baryon-baryon systems that might have bound states of a similar nature are listed.

description: Monophasic and homogeneous Ni10Zr7 nanocrystalline alloy films were successfully grown at room temperature by co-sputtering in an indigenously developed three-gun DC/RF magnetron sputtering unit. The films could be produced with long-range crystallographic and chemical order in the alloy, thus overcoming the widely acknowledged inherent proclivity of the glass forming Ni-Zr couple towards amorphization. Crystallinity of these alloys is a desirable feature with regard to improved efficacy in applications such as hydrogen storage, catalytic activity and nuclear reactor engineering, to name a few. Thermal stability of this crystalline phase, being vital for transition to viable applications, was investigated through systematic annealing of the alloy films at 473 K, 673 K and 923 K for various durations. While the films were stable at 473 K, the effect of annealing at 673 K was to create segregation into nanocrystalline Ni (superparamagnetic) and amorphous Ni+Zr (non-magnetic) phases. Detailed analyses of the physical and magnetic structures before and after annealing were performed through several techniques effectual in analyzing stratified configurations and the findings were all consistent with each other. Polarized neutron and X-ray reflectometry, grazing incidence x-ray diffraction, time-of-flight secondary ion mass spectroscopy and X-ray photoelectron spectroscopy were used to gauge phase separation at nanometer length scales. SQUID based magnetometry was used to investigate macroscopic magnetic properties. Simulated annealing performed on this system using molecular dynamic calculations corroborated well with the experimental results. This study provides a thorough understanding of the creation and thermal evolution of a crystalline Ni-Zr alloy.

description: Discovery of new functional materials is central to achieving radical advances in societally important challenges (efficient energy materials, organic solar cells, etc). The vast space of possible materials combinations and compositions gives hope that useful materials exist, but finding ways to navigate this vast space remains a fundamental challenge to materials research. Quantum theoretical computational materials research based on density functional theory has revolutionised the search for new materials over the last twenty years with its ability to predict materials properties based on atomic structure. However, the computational cost of solving quantum mechanical equations at high-performance computing centres remains a severe bottle-neck to its commonplace use in research. In this project, we use machine learning to develop an accurate quantum mechanical simulation method of structural, optical, and electronic properties of hybrid organic-metallic materials used in modern solar cells that is efficient enough to run on standard desktop computers for systems that include many thousands of atoms.

description: Line discontinuities in cosmic microwave background anisotropy maps are a distinctive prediction of models with cosmic strings. These signatures are visible in anisotropy maps with good angular resolution and should be identifiable using edge detection algorithms. One such algorithm is the Canny algorithm. We study the potential of this algorithm to pick out the line discontinuities generated by cosmic strings. By applying the algorithm to small-scale microwave anisotropy maps generated from theoretical models with and without cosmic strings, we find that, given an angular resolution of several minutes of arc, cosmic strings can be detected down to a limit of the mass per unit length of the string which is one order of magnitude lower than the current upper bounds.

description: Fermions in an optical lattice near a wide Feshbach resonance are expected to be described by an effective Hamiltonian of the general Hubbard model with particle-assisted tunneling rates resulting from the strong atomic interaction [Phys. Rev. Lett. 95, 243202 (2005)]. Here, we propose a scheme to unambiguously test the predictions of this effective Hamiltonian through manipulation of ultracold atoms in an inhomogeneous optical superlattice. The structure of the low-energy Hilbert space as well as the particle assisted tunneling rates can be inferred from measurements of the time-of-flight images.

description: Solar eruptions are spectacular magnetic explosions in the Sun's corona, and how they are initiated remains unclear. Prevailing theories often rely on special magnetic topologies that may not generally exist in the pre-eruption source region of corona. Here, using fully three-dimensional magnetohydrodynamic simulations with high accuracy, we show that solar eruptions can be initiated in a single bipolar configuration with no additional special topology. Through photospheric shearing motion alone, an electric current sheet forms in the highly sheared core field of the magnetic arcade during its quasi-static evolution. Once magnetic reconnection sets in, the whole arcade is expelled impulsively, forming a fast-expanding twisted flux rope with a highly turbulent reconnecting region underneath. The simplicity and efficacy of this scenario argue strongly for its fundamental importance in the initiation of solar eruptions.

In this case, the theory reduces to the one of SU(2)_L x SU(2)_R. Through this reduction, one can work out the strange quark mass dependence of the LECs in the two-flavour case. We present the pertinent relations at two-loop order for F,B and l_i.

description: We present the results from a survey of 57 low-redshift Abell galaxy clusters to study the radial dependence of the luminosity function (LF). The dynamical radius of each cluster, r200, was estimated from the photometric measurement of cluster richness, Bgc. The shape of the LFs are found to correlate with radius such that the faint-end slope, alpha, is generally steeper on the cluster outskirts. The sum of two Schechter functions provides a more adequate fit to the composite LFs than a single Schechter function. LFs based on the selection of red and blue galaxies are bimodal in appearance. The red LFs are generally flat for -22 < M_Rc < -18, with a radius-dependent steepening of alpha for M_Rc > -18. The blue LFs contain a larger contribution from faint galaxies than the red LFs. The blue LFs have a rising faint-end component (alpha ~ -1.7) for M_Rc > -21, with a weaker dependence on radius than the red LFs. The dispersion of M* was determined to be 0.31 mag, which is comparable to the median measurement uncertainty of 0.38 mag. This suggests that the bright-end of the LF is universal in shape at the 0.3 mag level. We find that M* is not correlated with cluster richness when using a common dynamical radius. Also, we find that M* is weakly correlated with BM-type such that later BM-type clusters have a brighter M*. A correlation between M* and radius was found for the red and blue galaxies such that M* fades towards the cluster center.

description: Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf-Rayet stars. The variability of these stars has been an area of study for both professional and amateur astronomers for more than a century. In this paper, we present five years of precision photometry of the classical LBV P Cygni taken with the BRITE-Constellation nanosatellites. We have analyzed these data with Fourier analysis to search for periodicities that could elucidate the drivers of variability for these stars. These data show some long-timescale variability over the course of all six calendar years of observations, but the frequencies needed to reproduce the individual light curves are not consistent from one year to the next. These results likely show that there is no periodic phenomenon present for P Cygni, meaning that the variability is largely stochastic. We interpret the data as being caused by internal gravity waves similar to those seen in other massive stars, with P Cygni exhibiting a larger amplitude and lower characteristic frequency than the main-sequence or blue supergiant stars previously studied. These results show evidence that LBVs may be an extrapolation of the blue supergiants, which have previously been shown to be an extension of main-sequence stars in the context of the stochastic low-frequency photometric variability.

It is observed as a critical phenomenon for hadron-nuclear, nuclear-nuclear interactions and ultrarelativistic heavy ion collisions. The existing simple models do not explain the effect. We believe that the responsible mechanism to explain the phenomena could be the percolation cluster formation and expect appearance of deconfinement in the cluster.

description: The magnetic properties of La0.7Ca0.3MnO3 (LCMO) manganite thin films were studied with magnetometry and ferromagnetic resonance as a function of film thickness. They maintain the colossal magnetoresistance behavior with a pronounced metal-insulator transition around 150-200 K, except for the very thinnest films studied (3 nm). Nevertheless, LCMO films as thin as 3 nm remain ferromagnetic, without a decrease in saturation magnetization, indicating an absence of dead-layers, although below approx. 6 nm the films remain insulating at low temperature. Magnetization hysteresis loops reveal that the magnetic easy axes lie in the plane of the film for thicknesses in the range of 4-15 nm. Ferromagnetic resonance studies confirm that the easy axes are in-plane, and find a biaxial symmetry in-plane with two, perpendicular easy axes. The directions of the easy axes with respect to the crystallographic directions of the cubic SrTiO3 substrate differ by 45 degrees in 4 nm and 15 nm thick LCMO films.

Growth and feeding of juvenile chinook salmon, Oncorhynchus Tshawytscha, in "in situ" enclosures
Creators: name: English, Karl K.
Publisher: name: University of British Columbia
Year: 2010

description: A feeding experiment was designed to examine how fish growth rates are affected by the size abundance of pelagic zooplankton. Juvenile chinook salmon, Oncorhynchus tshawytscha , were raised in 90 m³ mesh enclosures in Saanich Inlet, B.C. The enclosures permitted ample water and zooplankton circulation while retaining 5-6 gram juvenile salmon. The enclosed fish grew at an average rate of 1.8% wet body weight/day for a six week experimental period. Weekly growth rates ranged from 3.9%/day while food was abundant, to -0.5%/day when food was scarce. Several analytical methods were used to establish a relationship between fish gr.owth and the size and abundance of zooplankton in the enclosures. There is a strong relationship between the fish growth rates and the abundance of 1.4-4.5mm prey. Rates of successful search vary directly with the size and inherent contrast of a prey item. A minimum rate of successful search of 2.0m³/hour was estimated from a functional response curve for salmon feeding on 1.4-4.5mm zooplankton. This value is discussed in relation to a salmonids physical capabilities and results from previous field studies and tank experiments. Daily growth increments on the otoliths of the enclosed fish were examined with respect to daily variations in water temperature and zooplankton abundance. Extremes in food abundance appear to have a significant and consistent effect on the spacing of the growth rings. However, water temperatures would have to be kept constant in order to establish any closer relationship between food abundance and otolith growth rings.
Singularity Theory: Where Difference Does Not Collapse, but Gathers Itself

Subjects: ψ-theory, singularity, ontological physics, potentiality, difference, ψ-gravity, curvature, time, emergence, topology, structural genesis, philosophy of physics, cosmology

description: This article presents a novel ontological interpretation of singularity through the lens of ψ-theory. Contrary to traditional physics, which treats the singularity as a breakdown of space, time, and matter, this work proposes it as a structural knot of undifferentiated potential. Within ψ-theory, singularity becomes a point of internal contraction—where difference gathers into curvature rather than collapses into infinity. The paper introduces key mathematical structures, including the ψ-field, ψ-gravity, and a curvature threshold condition, to describe the emergence of time and form from a pre-structural ψ-state. This work positions the ψ-singularity as an ontologically necessary moment in the architecture of the cosmos, offering a groundbreaking alternative to standard cosmological models.

description: Due to the high efficiency of planet detections, current microlensing planet searches focus on high-magnification events. High-magnification events are sensitive to remote binary companions as well and thus a sample of wide-separation binaries are expected to be collected as a byproduct. In this paper, we show that characterizing binaries for a portion of this sample will be difficult due to the degeneracy of the binary-lensing parameters. This degeneracy arises because the perturbation induced by the binary companion is well approximated by the Chang-Refsdal lensing for binaries with separations greater than a certain limit. For binaries composed of equal mass lenses, we find that the lens binarity can be noticed up to the separations of $\sim 60$ times of the Einstein radius corresponding to the mass of each lens. Among these binaries, however, we find that the lensing parameters can be determined only for a portion of binaries with separations less than $\sim 20$ times of the Einstein radius.

description: Classically it is impossible to have transport without transit, i.e., if the points one, two and three lie sequentially along a path then an object moving from one to three must, at some point in time, be located at two. However, for a quantum particle in a three-well system it is possible to transport the particle between wells one and three such that the probability of finding it at any time in the classically accessible state in well two is negligible. We consider theoretically the analogous scenario for a Bose-Einstein condensate confined within a three well system. In particular, we predict the adiabatic transportation of an interacting Bose-Einstein condensate of 2000 Li atoms from well one to well three without transiting the allowed intermediate region. To an observer of this macroscopic quantum effect it would appear that, over a timescale of the order of one second, the condensate had transported, but not transited, a macroscopic distance of 20 microns between wells one and three.

description: We present a study of the mid-infrared properties and dust content of a sample of 27 HII ``blobs'', a rare class of compact HII regions in the Magellanic Clouds. A unique feature of this sample is that even though these HII regions are of high and low excitation they have nearly the same physical sizes ~1.5-3 pc. We base our analysis on archival 3-8 microns infrared imagery obtained with the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope. We find that despite their youth, sub-solar metallicity and varied degrees of excitation, the mid-infrared colors of these regions are similar to those of typical HII regions. Higher excitation ``blobs'' (HEBs) display stronger 8 micron emission and redder colors than their low-excitation counterparts (LEBs).

description: Using density functional theory within the LSDA + U method, we investigate the effect of strain on the spin state and magnetic ordering in perovskite lanthanum cobaltite, LaCoO3. We show that, while strain-induced changes in lattice parameters are insufficient to stabilize a non-zero spin state, additional heteroepitaxial symmetry constraints -- in particular the suppression of octahedral rotations -- stabilize a ferromagnetic intermediate-spin state. By comparing with experimental data for the bulk material, we calculate an upper bound on the Hubbard U value, and describe the role that the on-site Coulomb interaction plays in determining the spin-state configuration.

description: It is shown that the use of a density dependent effective Pauli potential together with a nucleon-nucleon interaction potential plays a crucial role to reproduce not only the binding energies but also the matter root mean square radii of medium mass range spin-isospin saturated nuclei. This study is performed with a semiclassical Monte Carlo many-body simulation within the context of a simplified nucleon-nucleon interaction to focus on the effect of the genuine correlations due to the fermionic nature of nucleons. The procedure obtained is rather robust and it does not depend on the detailed features of the nucleon-nucleon interaction. For nuclei below saturation the density dependence may be represented in terms either of the nucleon number, $A$, or the associated Fermi momenta. When testing the simulation procedure for idealized "infinite" symmetric nuclear matter within the corresponding range of densities, it turns out that finite size effects affect the Pauli potential strength parametrization in systems up to about 120 particles while remaining approximately stable for larger systems.

The effects of dose and duration of neuroleptic administration on dopamine receptor sensitivity
Creators: name: Dewey, Kevin John
Publisher: name: University of British Columbia
Year: 2010

description: It is well established that chronic treatment with neuroleptic agents which selectively block dopamine (DA) receptors in the brain leads to the development of DA receptor supersensitivity. However comparing the degree and duration of the changes in receptor sensitivity obtained by different investigators has been extremely difficult, because of the numerous differences that exist in individual methods of producing and examining DA receptor supersensitivity. By examining the DA receptor supersensitivity that ensues following chronic treatment with different doses and durations of pimozide, at various intervals after withdrawal from treatment, the overall parametric changes can be more directly compared. To measure the changes in DA receptor sensitivity following chronic pimozide treatment, both behavioral (d.-amphetamine-induced locomotor activity; apomorphine-induced stereotypy) and biochemical (DA receptor binding assay) techniques were utilized. With increasing doses of chronic pimozide treatment, the degree and duration of the resulting DA receptor supersensitivity increased as measured both behaviorally and biochemically. Similarily, the longer durations of chronic pimozide treatment had a greater effect on the degree and duration of the increased DA receptor sensitivity than did the shorter durations of treatment. Correlations were found between the biochemical and behavioral results both between groups of animals treated chronically with different doses and durations of pimozide and within individual groups of animals. In addition, the changes in receptor sensitivity following chronic pimozide treatment was due to an increase in the number of DA receptors with no change in the affinity of these receptors to DA. These results following chronic treatment with neuroleptics demonstrate that the behavioral supersensitivity observed in animals in response to either the direct DA agonist apomorphine or the indirect DA agonist d-amphetamine, may be a result of an increased number of DA receptors. Finally, the supersensitive DA receptors that develop as a result of chronic treatment with neuroleptics are discussed with regard to their possible relevance as an animal model of the iatrogenic disease, tardive dyskinesia, observed clinically in schizophrenic patients withdrawn from neuroleptic therapy.

description: The paper reports from one of the first efforts to generate data for a national register by automatically reusing data recorded in the clinical documentation process. Today, the process of reporting to national registries implies filling out a paper-based or electronic form as the final step of documenting patients’ treatment. The registries’ forms are hence not part of the patients’ Electronic Patient Record (EPR). Therefore, the Norwegian Directorate for e-health has established a program for developing a shared infrastructure for 51 national registers, aiming to improve the utilization and quality of the reported health data. We argue that the quality of the registries’ data rests heavily on an understanding of today’s practice and how and when to capture the data. This paper describes the initial work of facilitating automatic reuse of standardized clinical data recorded from the EPR to the Norwegian registry for spine surgery. The empirical setting is the regional FRESK (Future systems in the clinic) program (2017-2022), in the North Norwegian Health Region.
title: Infrastructuring knowledge in practice: designing self-experiments for type 2 Diabetes care

description: Healthcare institutions increasingly delegate the self-management of their condition to patients and their extended network: consequently, there is an increasing production of patient health data outside healthcare settings, also thanks to the increasing number of digital technologies able to assist in the collecting, interpretation and use of health data. This shift on the “personal” dimension of data has placed emphasis on self- knowledge practices supported by personal informatics systems. In the last years, studies on digital technologies supporting lifestyle-related diseases are becoming interested in the so-called “personal experiments”, emphasizing self-interpretation of patient- generated health data through self-reflection. In this paper I will present some preliminary points concerning my PhD research project, in which I’m following the co-design and implementation of technology-supported personal experiments aiming to encourage type 2 diabetes patients to collect personal health data and increase their motivation and self- knowledge.

description: Fostering innovation while maintaining a traditional IT infrastructure is challenging. We have conducted a qualitative study in the health sector, following three ICT-related innovation initiatives in a hospital. The innovators sought to connect the new solutions with the complex hospital digital infrastructure but the governance regime was not conducive to experimental development. We describe the challenges of relating to the existing information infrastructure and thereby identify the requirements for innovative projects to be sustained. In our analysis we zoom-in on the problematic “meeting points” between the innovation initiatives and the pre-existing infrastructure, as these reveal which capabilities and resources are required for the existing infrastructure to accomodate novelty. Conceptually, we frame these as boundary resources. Our study contributes a concrete description of the resources that are required if large, entrenched infrastructures shall be able to harness innovation.
title: “We can still talk to the patient!” - Negotiating the narrative power of patient reported data

description: Patient Reported Outcome data (PRO data) are standardized questionnaire data on patients’ own experience of their health and quality of life increasingly collected on digital platforms as part of treatment trajectories. In Denmark, national efforts are being put into developing questionnaires tools for meaningful clinical use of such data in cross-sectorial clinical pathways. PRO data is among other things seen as a way to enhance patient involvement by focusing the clinical encounter on “what matters to patients”. With increased datafication of healthcare, some see the power of the irreducible patient narrative set aside for quantified, standardized and thus reductive representations of the patient – PRO data potentially being a case in point. Rather than assuming such reductionism, in this paper I will explore empirically how health professionals engaged in developing PRO-tools enact the relationship between PRO data and more complex, narrative representations of the patient. Based on fieldwork in the national Danish initiative engaged in choosing and developing PRO-tools for heart- rehabilitation, I will suggest that PRO data is both enacted as an illumination of the patient narrative, a substitution for the narrative and an inhibitor of the narrative. The tensions between different enactments call for further reflections on the role of PRO in emergent digital health infrastructures.

description: ‘Healthcare infrastructures’ is often associated with large, complex and costly technical solutions made available by institutions. The widespread use of smart devices made possible the development of information exchange building on general purpose communication technologies. Through the analysis of an expert opinion service for breast cancer via WhatsApp, we illustrate the process of setting up the service, the challenges and the ramifications of health information exchange taking place through non-institutional channels. We introduce the concept of ‘grassroot infrastructures’ to indicate socio-technical systems created and managed by lower-ranked organizational actors, invisible to rationalized representations of work.

Women in low-income communities are disproportionately affected by HIV yet have been largely left out of efforts to raise awareness about pre-exposure prophylaxis (PrEP). To inform future awareness campaigns, we assessed women's current knowledge of and attitudes toward PrEP. We surveyed 184 women living in public housing communities in North Carolina regarding PrEP knowledge, attitudes, and perceived norms, as well as reported HIV-associated factors and perceived HIV acquisition chances. 38 women participated in eight focus group discussions (FGDs) addressing personal and community PrEP perceptions. Survey participants were 46 years old on average, and 86% identified as Black/African American. Only 35% had heard of PrEP, yet, after being told what it was, 61% said they probably or definitely would take PrEP in the next 6 months. Most women believed that if they decided to take PrEP, their partner (72%) or their family (66%) would approve. When asked about the importance of factors influencing their interest in PrEP, women most frequently rated possible side effects as important or very important (76%), followed by cost considerations (67% for cost of PrEP, 74% for cost of clinic visits and labs). In the FGDs, women had limited PrEP knowledge, but several had heard of PrEP from television commercials, which gave them the impression that PrEP was only for men. Women were concerned about potential side effects, interactions with other medications, safety during pregnancy, and the burden of daily dosing. Most FGD participants expressed generally positive attitudes toward PrEP, but some thought other women would be uninterested due to low perceived chances of HIV acquisition. Overall, these results suggest that while few women had previously heard of PrEP, most were interested in PrEP after receiving information about it and perceived positive community attitudes toward PrEP. Our findings indicate the importance of community-based PrEP communication that speaks to cisgender women, provides information on side effects, and offers destigmatized messaging regarding reasons for HIV prevention for women to consider.
