description: Studying the properties of ultra-dense matter is one of the key goals of modern neutron star research. The measurement of the tidal deformability from the inspiral of a binary neutron star merger offers one promising method for constraining the equation of state (EoS) of cold, dense matter. In this work, we report on a new class of EoSs which have significantly different pressures at nuclear densities and large differences in stellar radii, but that predict surprisingly similar tidal deformabilities across the entire range of astrophysically-observed neutron star masses. Using a survey of 5 million piecewise polytropic EoSs, subject to five different sets of nuclear priors, we demonstrate that these "tidal deformability doppelgangers" occur generically. We find that they can differ substantially in the pressure (by up to a factor of 3 at nuclear densities) and in the radius of intermediate-mass neutron stars (by up to 0.5 km), but are observationally indistinguishable in their tidal deformabilities ($ΔΛ< 30$) with the sensitivity of current gravitational wave detectors. We demonstrate that this near-degeneracy in the tidal deformability is a result of allowing for a phase transition at low densities. We show that a combination of input from nuclear theory (e.g., from chiral effective field theory), X-ray observations of neutron star radii, and/or the next generation of gravitational wave detectors will be able to significantly constrain these tidal deformability doppelgangers.

description: Individualized risk assessments during HIV testing are an integral component of prevention counseling, a currently recommended behavioral intervention for patients in high-risk settings. Additionally, aggregate risk assessment data are the source of aggregate behavioral statistics that inform prevention programs and allocation of resources. Consequently, inaccurate or incomplete risk behavior disclosure during test counseling may impact the efficacy of the counseling intervention, as well as bias aggregate behavioral statistics. To quantify client-reported accuracy during the risk assessment and identify barriers and facilitators to risk behavior disclosure, we interviewed young men accessing HIV testing services in a southeastern United States city using mixed methodology. Data were collected from August 2007 to April 2008. Based on data collected via an audio and computer-assisted self-interview (n = 203), over 30% of men reported that they were not accurate during the risk assessment. Participants reported numerous interpersonal facilitators to complete disclosure. During qualitative interviews (n = 25), participants revealed that many did not understand the purpose of the risk assessment. Findings suggest that risk assessments completed during HIV test counseling may be incomplete. Modifications to the risk assessment process, including better explaining the role of the risk assessment in prevention counseling, may increase the validity of the data.

description: Gauge fields are a central concept in fundamental theories of physics, and responsible for mediating long-range interactions between elementary particles. Recently, it has been proposed that dynamical gauge fields can be naturally engineered by photons in composite, neutral quantum gas--cavity systems using suitable atom-photon interactions. Here we comprehensively investigate nonequilibrium dynamical phases appearing in a two-leg bosonic lattice model with leg-dependent, dynamical complex tunnelings mediated by cavity-assisted two-photon Raman processes. The system constitutes a minimal dynamical flux-lattice model. We study fixed points of the equations of motion and their stability, the resultant dynamical phase diagram, and the corresponding phase transitions and bifurcations. Notably, the phase diagram features a plethora of nonequilibrium dynamical phases including limit-cycle and chaotic phases. In the end, we relate regular periodic dynamics (i.e., limit-cycle phases) of the system to time crystals.

description: We infer the emission positions of twin kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low mass X-ray binaries (NS-LMXBs) based on the Alfven wave oscillation model (AWOM). For most sources, the emission radii of kHz QPOs cluster around a region of 16-19 km with the assumed NS radii of 15 km. Cir X-1 has the larger emission radii of 23-38 km than those of the other sources, which may be ascribed to its large magnetosphere-disk radius or strong NS surface magnetic field. SAX J1808.4-3658 is also a particular source with the relative large emission radii of kHz QPOs of 20 - 23 km, which may be due to its large inferred NS radius of 18 - 19 km. The emission radii of kHz QPOs for all the sources are larger than the NS radii, and the possible explanations of which are presented. The similarity of the emission radii of kHz QPOs (16-19 km) for both the low/high luminosity Atoll/Z sources is found, which indicates that both sources share the similar magnetosphere- disk radii.

description: With the continued transmission of HIV each year, novel approaches to HIV prevention are needed. Since 2003, the U.S. HIV prevention focus has shifted from primarily targeting HIV-negative at-risk persons to including safer sex programs for people already infected with HIV. At least 20–30% of people infected with HIV engage in risky sexual practices. Based on these data, policymakers have recommended that interventionists develop strategies to help HIV-infected people reduce their risky sexual behaviors. In the past, the few safer sex interventions that targeted HIV-infected people met with limited success because they basically adapted strategies previously used with HIV-uninfected individuals. In addition, often these adaptations did not address issues of serostatus disclosure, HIV stigma, or motivation to protect others from HIV. We had previously tested, in a demonstration project named the Start Talking About Risks (STAR) Program, a monthly three-session motivational interviewing (MI)-based intervention to help people living with HIV practice safer sex. In this study, we refined that program by enhancing its frequency and intensity and adding written and audio components to support the counseling. We theorized that an intervention such as MI, which is tailored to each individual's circumstances more than standardized prevention messages, would be more successful when supplemented with other components. We qualitatively assessed participants' perceptions, reactions, and preferences to the refined prevention with positives counseling program we called SafeTalk and learned that participants found the SafeTalk MI counseling and educational materials appealing, understandable, and relevant to their lives.

description: By using the conformal symmetry between Brans-Dicke action with $ω=-\frac{3}{2}$ and O'Hanlon action, we seek the O'Hanlon actions in Einstein frame respecting the Noether symmetry. Since the Noether symmetry is preserved under conformal transformations, the existence of Noether symmetry in the Brans-Dicke action asserts the Noether symmetry in O'Hanlon action in Einstein frame. Therefore, the potentials respecting Noether symmetry in Brans-Dicke action give the corresponding potentials respecting Noether symmetry in O'Hanlon action in Einstein frame.

description: HIV-infected children in developing countries are living longer lives as they gain access to antiretroviral treatment programs. As they grow older, their parents/guardians are faced with the difficult decision of if, when, and how to inform their child of his/her HIV status. Both negative and positive social, psychological, and behavioral impacts of disclosure to children have been reported, including improved adherence to medication regimens. Understanding the disclosure process from the perspective of HIV positive children, therefore, is critical to developing these interventions. Through children's experiences we can learn about what works well, what needs to be strengthened, and what is missing in current disclosure practices. We conducted in-depth interviews with eight caregiver–child dyads in Kinshasa, Democratic Republic of the Congo. The children were in a comprehensive HIV pediatric care and treatment program and had already been told their HIV diagnosis. For the analysis we placed particular emphasis on children's reports of communication with their caregivers and health care providers about their illness. Patterns emerged of limited communication between children and their caregivers as well as their providers, before, during, and after disclosure. From the perspective of children in this study, disclosure was largely a discrete event rather than a process. Sociocultural contexts surrounding HIV/AIDS, as well as health status, variations in parent–child communication and the relationships between health providers and children under their care, should inform psychosocial interventions delivered alongside treatment programs.

description: We study continuous variable systems, in which quantum and classical degrees of freedom are combined and treated on the same footing. Thus all systems, including the inputs or outputs to a channel, may be quantum-classical hybrids. This allows a unified treatment of a large variety of quantum operations involving measurements or dependence on classical parameters. The basic variables are given by canonical operators with scalar commutators. Some variables may commute with all others and hence generate a classical subsystem. We systematically study the class of "quasifree" operations, which are characterized equivalently either by an intertwining condition for phase-space translations or by the requirement that, in the Heisenberg picture, Weyl operators are mapped to multiples of Weyl operators. This includes the well-known Gaussian operations, evolutions with quadratic Hamiltonians, and "linear Bosonic channels", but allows for much more general kinds of noise. For example, all states are quasifree. We sketch the analysis of quasifree preparation, measurement, repeated observation, cloning, teleportation, dense coding, the setup for the classical limit, and some aspects of irreversible dynamics, together with the precise salient tradeoffs of uncertainty, error, and disturbance. Although the spaces of observables and states are infinite dimensional for every non-trivial system that we consider, we treat the technicalities related to this in a uniform and conclusive way, providing a calculus that is both easy to use and fully rigorous.

description: Spin-wave technology (magnonics) has the potential to further reduce the size and energy consumption of information processing devices. In the submicrometer regime (exchange spin waves), topological defects such as domain walls may constitute active elements to manipulate spin waves and perform logic operations. We predict that spin waves that pass through a domain wall in an ultrathin perpendicular-anisotropy film experience a phase shift that depends on the orientation of the domain wall (chirality). The effect, which is absent in bulk materials, originates from the interfacial Dzyaloshinskii-Moriya interaction and can be interpreted as a geometric phase. We demonstrate analytically and by means of micromagnetic simulations that the phase shift is strong enough to switch between constructive and destructive interference. The two chirality states of the domain wall may serve as a memory bit or spin-wave switch in magnonic devices.

description: Packet networks need to maintain state in the form of forwarding tables at each switch. The cost of this state increases as networks support ever more sophisticated per-flow routing, traffic engineering, and service chaining. Per-flow or per-path state at the switches can be eliminated by encoding each packet's desired path in its header. A key component of such a method is an efficient encoding of paths through the network. We introduce a mathematical formulation of this optimal path-encoding problem. We prove that the problem is APX-hard, by showing that approximating it to within a factor less than 8/7 is NP-hard. Thus, at best we can hope for a constant-factor approximation algorithm. We then present such an algorithm, approximating the optimal path-encoding problem to within a factor 2. Finally, we provide empirical results illustrating the effectiveness of the proposed algorithm.

description: Despite the need for HIV-positive children to adhere effectively to antiretroviral treatment (ART), a guiding theory for pediatric ART in resource-limited settings is still missing. Understanding factors that influence pediatric ART adherence is critical to developing adequate strategies. In-depth qualitative interviews were undertaken in Kinshasa, Democratic Republic of the Congo, with 20 sets of HIV disclosed and nondisclosed children along with respective caregivers to better characterize barriers, facilitators, and adherence experiences in children taking ART. Commonly cited barriers included lack of food or nutritional support, lack of assistance or supervision for children, lack of assistance for caregivers, and being unable to remember to take medicines on a consistent basis. Facilitators included having a strong caregiver–child relationship and support system along with strategies for maintaining adherence. Similar themes arose within the child–caregiver sets, but were often characterized differently between the two. Children who were aware of their HIV status displayed fewer instances of frustration and conflict concerning taking medicines and within the child–caregiver relationship. Continued study on pediatric ART adherence should account for differing perspectives of children and caregivers, as well as between status disclosed and nondisclosed children. Areas of future intervention should focus on child–caregiver relationships, disclosure of HIV status, and available nutritional and psychosocial support for children and their caregivers.

description: Next generation direct dark matter detection experiments are favorable facilities to probe neutrino properties and light mediators beyond the Standard Model. We explore the implications of the recent data reported by LUX-ZEPLIN (LZ) and XENONnT collaborations on electromagnetic neutrino interactions and neutrino generalized interactions (NGIs). We show that XENONnT places the most stringent upper limits on the effective and transition neutrino magnetic moment (of the order of few $\times 10^{-12}~μ_B$) as well as stringent constraints to neutrino millicharge (of the order of $\sim 10^{-13}~e$)--competitive to LZ--and improved by about one order of magnitude in comparison to existing constraints coming from Borexino and TEXONO. We furthermore explore the XENONnT and LZ sensitivities to simplified models with light NGIs and find improved constraints in comparison to those extracted from Borexino-Phase II data.

Internal phase transition induced by external forces in Finsler geometric model for membranes

description: We numerically study an anisotropic shape transformation of membranes under external forces for two-dimensional triangulated surfaces on the basis of Finsler geometry. The Finsler metric is defined by using a vector field, which is the tangential component of a three dimensional unit vector $σ$ corresponding to the tilt or some external macromolecules on the surface of disk topology. The sigma model Hamiltonian is assumed for the tangential component of $σ$ with the interaction coefficient $λ$. For large (small) $λ$, the surface becomes oblong (collapsed) at relatively small bending rigidity. For the intermediate $λ$, the surface becomes planar. Conversely, fixing the surface with the boundary of area $A$ or with the two point boundaries of distance $L$, we find that the variable $σ$ changes from random to aligned state with increasing of $A$ or $L$ for the intermediate region of $λ$. This implies that an internal phase transition for $σ$ is triggered not only by the thermal fluctuations but also by external mechanical forces. We also find that the frame (string) tension shows the expected scaling behavior with respect to $A/N$ ($L/N$) at the intermediate region of $A$ ($L$) where the $σ$ configuration changes between the disordered and ordered phases. Moreover, we find that the string tension $γ$ at sufficiently large $λ$ is considerably smaller than that at small $λ$. This phenomenon resembles the so-called soft-elasticity in the liquid crystal elastomer, which is deformed by small external tensile forces.

description: Given the continued high incidence of HIV infection in the United States among racial/ethnic minority young men who have sex with men (YMSM), and an appreciation that antiretroviral therapy (ART) can provide personal and public health benefits, attention is needed to enhance the detection of HIV-infected youth and engage them in medical care and support services that encourage sustained HIV treatment and suppression of viremia. Poor retention in clinical care has been associated with higher mortality, an increase in HIV RNA, and decreased CD4 cell count. The goal of the current study was to evaluate the health care utilization and health outcomes of HIV-infected racial/ethnic minority YMSM enrolled in an outreach, linkage, and retention study funded by the Health Resources and Services Administration (HRSA) HIV/AIDS Bureau (HAB). We hypothesized that among racial/ethnic minority YMSM, baseline CD4 counts and usage of ART are influenced by age, race, drug and alcohol use, and mental health symptoms. Overall, 155 subjects had at least a baseline CD4 count recorded at study entry. There was a low rate of ART use in this population with only one-half of the cohort with CD4 counts ≤350 cells/mm3 being prescribed ART to treat their infection. However, of those youth who were started on ART, the majority (74%) did achieve undetectable viral loads (<400 copies). Given the continued increase in cases of HIV infection among racial/ethnic minority YMSM, efforts to increase both the provision of ART and support services that encourage adherence in this population are warranted.

description: We investigate the nature of the long-period radial velocity variations in Alpha Tau first reported over 20 years ago. We analyzed precise stellar radial velocity measurements for Alpha Tau spanning over 30 years. An examination of the Halpha and Ca II 8662 spectral lines, and Hipparcos photometry was also done to help discern the nature of the long-period radial velocity variations. Our radial velocity data show that the long-period, low amplitude radial velocity variations are long-lived and coherent. Furthermore, Halpha equivalent width measurements and Hipparcos photometry show no significant variations with this period. Another investigation of this star established that there was no variability in the spectral line shapes with the radial velocity period. An orbital solution results in a period of P = 628.96 +/- 0.90 d, eccentricity, e = 0.10 +/- 0.05, and a radial velocity amplitude, K = 142.1 +/- 7.2 m/s. Evolutionary tracks yield a stellar mass of 1.13 +/- 0.11 M_sun, which corresponds to a minimum companion mass of 6.47 +/- 0.53 M_Jup with an orbital semi-major axis of a = 1.46 +/- 0.27 AU. After removing the orbital motion of the companion, an additional period of ~ 520 d is found in the radial velocity data, but only in some time spans. A similar period is found in the variations in the equivalent width of Halpha and Ca II. Variations at one-third of this period are also found in the spectral line bisector measurements. The 520 d period is interpreted as the rotation modulation by stellar surface structure. Its presence, however, may not be long-lived, and it only appears in epochs of the radial velocity data separated by $\sim$ 10 years. This might be due to an activity cycle. The data presented here provide further evidence of a planetary companion to Alpha Tau, as well as activity-related radial velocity variations.

description: Significant pharmacokinetic interactions can result between acid-suppressing agents and some protease inhibitors (PIs) in the management of HIV infection. In healthy subjects, famotidine, an H2-receptor antagonist, reduces exposures of atazanavir by 4–28% at doses of 20–40 mg twice daily. This study evaluated the effect of famotidine 20–40 mg twice daily on the pharmacokinetics of atazanavir/ritonavir 300/100 mg once daily with and without tenofovir disoproxil fumarate (TDF) 300 mg in HIV-infected patients (n=40; 87.5% male; mean age 42, range 26–63 years; 55% white). Coadministration of famotidine 40 mg and atazanavir/ritonavir to HIV-infected patients reduced exposures of atazanavir by approximately 20%. This is comparable to reductions seen in HIV-uninfected subjects. Coadministration of famotidine 20 mg had less impact on atazanavir exposures, with no reduction of atazanavir geometric mean plasma concentration at 24 h postdose (Cmin). In the presence of TDF, administration of famotidine 20–40 mg twice daily 2 h after and 10 h before atazanavir/ritonavir reduced exposures of atazanavir by 19–25%. However, all individual atazanavir Cmin values remained at least five-fold above the population mean protein-binding adjusted 90% maximum effect (EC90) against wild-type HIV (14 ng/mL). No viral load rebound was observed at end of study. The results confirmed that coadministration of an H2-receptor antagonist with atazanavir/ritonavir in HIV-infected patients resulted in similar magnitude of reductions in atazanavir exposures as in healthy subjects. This supports the current dose recommendations for coadministration of an H2-receptor antagonist with atazanavir/ritonavir.

description: A hydrodynamic model for small acoustic oscillations in a cloud of stars is built, taking into account the self-consistent gravitational field in equilibrium with a non-zero second correlation moment. It is assumed that the momentum flux density tensor should include the analog of the anisotropic pressure tensor and the second correlation moment of both longitudinal and transverse gravitational field strength. The non-relativistic temporal equation for the second correlation moment of the gravitational field strength is derived from the Einstein equations using the first-order post-Newtonian approximation. One longitudinal and two transverse branches of acoustic oscillations are found in a homogeneous and isotropic star cloud. The requirement for the velocity of transverse oscillations to be zero provides the boundary condition for the stability of the cloud. The critical radius of the spherical cloud of stars is obtained, which is precisely consistent with the virial theorem.

description: Young men who have sex with men (YMSM) of color are at particularly increased risk for HIV infection compared to white MSM. National data highlight the need to link YMSM of color to care to improve their overall health and stem further infections, yet, there is limited data on interventions and clinical outcomes focused on engaging and retaining youth, specifically HIV-infected YMSM of color in care. To address the medical care needs of this underserved population, in 2005, the Health Research and Services Administration (HRSA) created the YMSM of Color Initiative. Utilizing a social marketing campaign targeting youth and members of their sexual and social networks, testing and outreach on college campuses and within the broader community, and a tightly linked medical–social support network, we created STYLE (Strength Through Youth Livin’ Empowered), a novel intervention that sought to diagnose, engage, and retain HIV-positive black and Latino YMSM in HIV primary care services. Over a 3-year period, 81 men were either newly diagnosed or reengaged in care. Overall, 63% of the cohort was retained in clinical care; defined as attending at least one medical visit every 4 months. Compared to the 3 years prior to STYLE, the odds ratio for whether or not someone attended a clinic visit was 2.58 (95% confidence interval [CI] 1.34–4.98) if enrolled in STYLE. We conclude that compared to a pre-STYLE cohort, STYLE was an effective intervention that increased HIV diagnoses, provided efficient and timely engagement in care for both those newly diagnosed and those who had fallen out of care and improved overall retention.

description: We present new parton distribution functions (PDFs) up to next-to-next-to-leading order (NNLO) from the CTEQ-TEA global analysis of quantum chromodynamics. These differ from previous CT PDFs in several respects, including the use of data from LHC experiments and the new D0 charged lepton rapidity asymmetry data, as well as the use of more flexible parametrization of PDFs that, in particular, allows a better fit to different combinations of quark flavors. Predictions for important LHC processes, especially Higgs boson production at 13 TeV, are presented. These CT14 PDFs include a central set and error sets in the Hessian representation. For completeness, we also present the CT14 PDFs determined at the leading order (LO) and the next-to-leading order (NLO) in QCD. Besides these general-purpose PDF sets, we provide a series of (N)NLO sets with various $α_s$ values and additional sets in general-mass variable flavor number (GM-VFN) schemes, to deal with heavy partons, with up to 3, 4, and 6 active flavors.
