The Size, Shape, and Scattering of Sagittarius A* at 86 GHz: First VLBI with ALMA

The Galactic center supermassive black hole Sagittarius A* (Sgr A*) is one of the most promising targets to study the dynamics of black hole accretion and outflow via direct imaging with very long baseline interferometry (VLBI). At 3.5 mm (86 GHz), the emission from Sgr A* is resolvable with the Global Millimeter VLBI Array (GMVA). We present the first observations of Sgr A* with the phased Atacama Large Millimeter/submillimeter Array (ALMA) joining the GMVA. Our observations achieve an angular resolution of ~87 μas, improving upon previous experiments by a factor of two. We reconstruct a first image of the unscattered source structure of Sgr A* at 3.5 mm, mitigating the effects of interstellar scattering. The unscattered source has a major-axis size of 120 ± 34 μas (12 ± 3.4 Schwarzschild radii) and a symmetrical morphology (axial ratio of 1.2_(-0.2)^(+0.3)), which is further supported by closure phases consistent with zero within 3σ. We show that multiple disk-dominated models of Sgr A* match our observational constraints, while the two jet-dominated models considered are constrained to small viewing angles. Our long-baseline detections to ALMA also provide new constraints on the scattering of Sgr A*, and we show that refractive scattering effects are likely to be weak for images of Sgr A* at 1.3 mm with the Event Horizon Telescope. Our results provide the most stringent constraints to date for the intrinsic morphology and refractive scattering of Sgr A*, demonstrating the exceptional contribution of ALMA to millimeter VLBI

Improving Work Supports: Using the Family Resource Simulator to Identify Problems and Test Solutions

Neither the federal government, nor the states, has a coordinated or comprehensive work supports system. The current work supports system is comprised of a patch work of programs, such as EITC, child care programs, food stamps, Medicaid, SCHIP, and TANF. As a result of this disjointed history, these work support programs do not always help working parents meet their families\u27 needs. Using the Family Resource Simulator, a web-based policy tool, the authors make specific suggestions for how to improve the Illinois work support system. First, the Article present the landscape of work support systems and how they affect working families as income rises. Next, the Article shows the benefits of the Illinois work supports programs and also spotlights where the programs leave gaps or policy problems. Finally, the Article shows how the simulator can be used to model policy solutions to the problems revealed by the Article

The acceptability of cognitive behaviour therapy in Indonesian community health care

Cognitive behaviour therapy (CBT) is considered to be the most empirically supported treatment in the Western world. However, many authors emphasize the need for cultural adaptations of CBT for patients in a non-Western context. Before considering such adaptations, it is important to investigate the reasons and the degree to which this type of treatment should be adapted. One important factor is the acceptability of CBT by local health care consumers in non-Western countries, for which there is only very limited empirical evidence. This explorative study aimed to investigate the acceptability of CBT's principles and specific interventions in Indonesia. Lectures and video clips were developed, demonstrating various mainstream CBT principles and procedures. These were presented to 32 out-patients and mental health volunteers from various Indonesian community health centres (Puskesmas), who were asked to rate to what extent they considered the presented materials to be acceptable in accordance with their personal, family, cultural and religious values. Acceptance in all four value domains was rated as very high for the general features of CBT, as well as for the content of the video clips. There were no significant differences in acceptability between the value domains. The presented study suggests that mainstream CBT applications, which are slightly culturally adapted in terms of language, therapist-patient interaction and presentation, might resonate well with consumers in community health centres in Indonesia. Key learning aims (1) Adapting CBT to non-Western patients should be based on empirical evidence. (2) The potential need for adaptation of CBT might depend on the acceptability of unadapted CBT. (3) Acceptability is assumed to be related to patients' values

Direct microwave measurement of Andreev-bound-state dynamics in a proximitized semiconducting nanowire

The modern understanding of the Josephson effect in mesosopic devices derives from the physics of Andreev bound states, fermionic modes that are localized in a superconducting weak link. Recently, Josephson junctions constructed using semiconducting nanowires have led to the realization of superconducting qubits with gate-tunable Josephson energies. We have used a microwave circuit QED architecture to detect Andreev bound states in such a gate-tunable junction based on an aluminum-proximitized InAs nanowire. We demonstrate coherent manipulation of these bound states, and track the bound-state fermion parity in real time. Individual parity-switching events due to non-equilibrium quasiparticles are observed with a characteristic timescale $T_\mathrm{parity} = 160\pm 10~\mathrm{\mu s}$. The $T_\mathrm{parity}$ of a topological nanowire junction sets a lower bound on the bandwidth required for control of Majorana bound states
