description: Collinear laser spectroscopy of fast atomic beams has been established as one of the main tools to perform precision experiments with atoms containing short-lived nuclei. Although highly sensitive, the spectral resolution of these techniques is typically limited to several MHz. Here, we study the use of transient interference phenomena to potentially improve the experimental resolution. Previous attempts to implement Ramsey-type measurements with fast beams were limited by the lack of understanding of the observed line shapes. By using a simple model, we provide a satisfactory description of the previously observed line shapes, and propose alternative experimental schemes to improve the resolution in fast ion-beam experiments.

Year: 2022
Subjects: subject: Applied Physics (physics.app-ph)
subject: FOS: Physical sciences

description: We design and demonstrate a compact, robust and simple to assemble and tune permanent magnet suitable for NMR relaxometry measurements of microfluidic flows. Soft-magnetic stainless steel plates, incorporated inside the magnet airgap, are key for obtaining substantially improved and tunable field homogeneity. The design is scalable for different NMR probe sizes with the region of suitable field homogeneity, less than 200 ppm, achievable in a capillary length of about 50% of the total magnet length. The built physical prototype, having 3.5x3.5x8.0 cm3 in size and 5 mm high airgap, provides a field strength of 0.5 T and sufficient field homogeneity for NMR relaxometry measurements in capillaries up to 1.6 mm i.d. and 20 mm long. The magnet was used for test flow rate measurements in a wide range, from 0.001 ml/min to 20 ml/min.

African American College Students’ Attitudes About HIV and AIDS: An assessment of HIV knowledge and attitudes and current prevention strategies
Creators: name: Campbell, Timica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Background: Until recently, African American college students were not considered to be a high risk population for HIV. Epidemiologic data reveals that the HIV incidence and prevalence in this group is significantly higher than that of white college students, and these numbers are rising. Objective: To describe the HIV knowledge, attitudes and preventive or risk-taking behaviors of African American undergraduates in an attempt to better understand the causes for this increased incidence and to assess current prevention strategies. Methods: In-depth interviews with African American undergraduate students from both Historically Black Colleges/Universities and Traditionally White Institutions and a systematic review and critical appraisal of the literature. Findings: The media are the most influential source of information for HIV, but not enough of this information they present is distributed to students. Despite this lack of information, students are knowledgeable on the subject, though their answers show that many of the myths and misconceptions still exist about the virus. Students recognize the need for being tested for HIV, and are able to discuss testing with close friends, but the stigma that surrounds HIV-infected individuals and HIV testing is large enough to present a barrier to testing. Among other testing barriers, the most notable were a fear of a breech in confidentiality when seeking testing and a fear of knowing one’s HIV status. Some university policies and practices may contribute to these barriers. Conclusion: The public health community must increase the amount of HIV knowledge promoted in the media. New methods of prevention must be developed that help students understand HIV risk and discussions of safe sex methods with partners.
Stellar winds can affect gas dynamics in debris disks and create observable belt winds

description: Context: Gas is now detected in many extrasolar systems around mature stars aged between 10 Myr to $\sim$ 1 Gyr with planetesimal belts. Gas in these mature disks is thought to be released from planetesimals and has been modelled using a viscous disk approach. At low densities, this may not be a good assumption as the gas could be blown out by the stellar wind instead. Methods: We developed an analytical model for A to M stars that can follow the evolution of gas outflows and target when the transition occurs between a disk or a wind. The crucial criterion is the gas density for which gas particles stop being protected from stellar wind protons impacting at high velocities on radial trajectories. Results: We find that: 1) Belts of radial width $ΔR$ with gas densities $< 7 \, (ΔR/50 {\rm \, au})^{-1}$ cm$^{-3}$ would create a wind rather than a disk, which would explain the recent outflowing gas detection in NO Lup. 2) The properties of this belt wind can be used to measure stellar wind properties such as their densities and velocities. 3) Debris disks with low fractional luminosities $f$ are more likely to create gas winds, which could be observed with current facilities. Conclusions: The systems containing low gas masses such as Fomalhaut or TWA 7 or more generally, debris disks with fractional luminosities $f \lesssim 10^{-5} (L_\star/L_\odot)^{-0.37} $ or stellar luminosity $\gtrsim 20 \, L_\odot$ (A0V or earlier) would rather create gas outflows (or belt winds) than gas disks. Gas observed to be outflowing at high velocity in the young system NO Lup could be an example of such belt winds. The detection of these gas winds is possible with ALMA (CO and CO$^+$ could be good wind tracers) and would allow us to constrain the stellar wind properties of main-sequence stars, which are otherwise difficult to measure.

description: The lecture covers the current state of knowledge on the potential impact of aviation on the environment, concentrating on climate change whilst also mentioning the local issues around airports. Due to the very long timescales for aircraft fleet turn over it is urgent to implement the necessary research to more fully understand the behaviour of the atmosphere and to be able to achieve substantial reductions in CO2 and other emissions in future aircraft design and operation. Whilst the current effect of aviation is relatively low, with the predicted growth rates in travel, the impact on climate change may become far more significant in the future. The lecture goes on to review some of the technology and regulatory options for the future of air travel.

description: Semiconductor nanowire lasers can be subject to modifications of their lasing threshold resulting from a variation of their environment. A promising choice is to use metallic substrates to gain access to low-volume Surface-Plasmon-Polariton (SPP) modes. We introduce a simple, yet quantitatively precise model that can serve to describe mode competition in nanowire lasers on metallic substrates. We show that an aluminum substrate can decrease the lasing threshold for ZnO nanowire lasers while for a silver substrate, the threshold increases compared with a dielectric substrate. Generalizing from these findings, we make predictions describing the interaction between planar metals and semiconductor nanowires, which allow to guide future improvements of highly-integrated laser sources.
Understanding the Characteristics of Patients who are High Utilizers of Emergency Departments
Creators: name: Hardy, Morgan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Background: Patients with high rates of emergency department (ED) and hospital use have attracted increased attention because of the potential to intervene to reduce costs while improving quality of care. The mixed results from various various high utilizer interventions suggest an inadequate understanding of patient needs and the factors that drive high utilization. This study seeks to understand the underlying drivers behind repeated ED use by analyzing patterns in the reasons patients present to the ED. Methods: Patients enrolled at an academically-affiliated general internal medicine clinic were categorized and compared according to patterns of ED use during a 12-month period (July 1, 2014 to June 30, 2015): non-utilizers (0 ED visits, n=2441), non-high utilizers (1-4 ED visits, n=1386), and high utilizers (n≥5, n=260). For all ED visits during the same period, the leading chief complaints, admission rates by complaint, and average number of repeat visits for the same complaint were analyzed for high utilizers and non-high utilizers. Discharge diagnoses associated with leading chief complaints were categorized according to the NYU ED algorithm to assess preventability of visits based on complaint. Charts from ten of the highest utilizers from each of the 3 leading chief complaints (n=30) received an in-depth review to assess the underlying factors behind high patterns of ED use for the same complaints. Results: High utilizers demonstrated a much higher burden of chronic disease, mental illness, and substance abuse than other patients. The presenting chief complaints of high utilizers were statistically similar to non-high utilizers. High utilizers were more likely to present multiple times for the same chief complaints (mean repeat visits 2.4 vs 1.2), especially for specific complaints. Abdominal pain, chest pain, and shortness of breath were the leading chief complaints overall, leading causes of admissions, and leading causes of repeat visits among high utilizers. Around 50% of diagnoses for abdominal pain and chest pain were non-specific, and over 40% were considered primary care-treatable. Shortness of breath was much more likely to be associated with definitive diagnoses and much less likely to be primary care-treatable (24%). Chart review revealed that repeated visits for all 3 chief complaints were often associated with substance abuse, anxiety, and treatment non-adherence. Conclusion: The reasons for high utilization are complex, but can be better understood by examining patterns in ED use. This study suggests that we can target certain patients based on patterns of repeated visits for the same complaint.

description: We use two zoom-in $Λ$CDM hydrodynamical simulations of massive disk galaxies to study the possible existence of fixed satellite groups showing a kinematically-coherent behaviour across evolution (angular momentum conservation and clustering). We identify three such groups in the two simulations, defining kinematically-coherent, time-persistent planes (KPPs) that last at least from virialization to $z=0$ (more than 7 Gyrs). This proves that orbital pole clustering is not necessarily set in at low redshift, representing a long-lived property of galaxy systems. KPPs are thin and oblate, represent $\sim25-40\%$ of the total number of satellites in the system, and are roughly perpendicular to their corresponding central disk galaxies during certain periods, consistently with Milky Way $z=0$ data. KPP satellite members are statistically distinguishable from satellites outside KPPs: they show higher specific orbital angular momenta, orbit more perpendicularly to the central disk galaxy, and have larger pericentric distances, than the latter. We numerically prove, for the first time, that KPPs and the best-quality positional planes share the same space configuration across time, such that KPPs act as `skeletons' preventing the latter of being washed out in short timescales. In one of the satellite-host systems, we witness the late capture of a massive dwarf galaxy endowed with its own satellite system, also organized into a KPP configuration prior to its capture. We briefly explore the consequences this event has on the host's KPP, and on the possible enhancement of the asymmetry in the number of satellites rotating in one sense or the opposite within the KPP.

description: In the railway domain, an interlocking is a computerised system that controls the railway signalling objects in order to allow a safe operation of the train traffic. Each interlocking makes use of particular data, called application data, that reflects the track layout of the station under control. The verification and validation of the application data are performed manually and is thus error-prone and costly. In this paper, we explain how we built an executable model in NuSMV of a railway interlocking based on the application data. We also detail the tool that we have developed in order to translate the application data into our model automatically. Finally we show how we could verify a realistic set of safety properties on a real-size station model by customizing the existing model-checking algorithm with PyNuSMV a Python library based on NuSMV.

The role of Coulomb anti-blockade in the photoassociation of long-range Rydberg molecules

description: We present a new mechanism contributing to the detection of photoassociated long-range Rydberg molecules via pulsed-field ionization: ionic products, created by the decay of a long-range Rydberg molecule, modify the excitation spectrum of surrounding ground-state atoms and facilitate the excitation of further atoms into Rydberg states by the photoassociation light. Such an ion-mediated excitation mechanism has been previously called "Coulomb anti-blockade". Pulsed-field ionisation typically doesn't discriminate between the ionization of a long-range Rydberg molecule and an isolated Rydberg atom, and thus the number of atomic ions detected by this mechanism is not proportional to the number of long-range Rydberg molecules present in the probe volume. By combining high-resolution UV and RF spectroscopy of a dense, ultracold gas of cesium atoms, theoretical modeling of the molecular level structures of long-range Rydberg molecules bound below nP_3/2 Rydberg states of cesium, and a rate model of the photoassociation and decay processes, we unambiguously identify the signatures of this detection mechanism in the photoassociation of long-range Rydberg molecules bound below atomic asymptotes with negative Stark shifts.

description: 2D and 4D transverse phase-space of a low-energy ion-beam is measured with two of the most common emittance scanners. The article covers the description of the installation, the setup, the settings, the experiment and the benchmark of the two emittance meters. We compare the results from three series of measurements and present the advantages and drawbacks of the two systems. Coupling between phase-space planes, correlations and mitigation of deleterious effects are discussed. The influence of background noise and aberrations of trace-space figures on emittance measurements and RMS calculations is highlighted, especially for low density beams and halos. A new data analysis method using noise reduction, filtering, and reconstruction of the emittance figure is described. Finally, some basic concepts of phase-space theory and application to beam transport are recalled.

description: A universal characteristic of mesoscale turbulence in active suspensions is the emergence of a typical vortex length scale, distinctly different from the scale-invariance of turbulent high-Reynolds number flows. Collective length-scale selection has been observed in bacterial fluids, endothelial tissue and active colloides, yet the physical origins of this phenomenon remain elusive. Here, we systematically derive an effective fourth-order field theory from a generic microscopic model that allows us to predict the typical vortex size in microswimmer suspensions. Building on a self-consistent closure condition, the derivation shows that the vortex length scale is determined by the competition between local alignment forces and intermediate-range hydrodynamic interactions. Vortex structures found in simulations of the theory agree with recent measurements in Bacillus subtilis suspensions. Moreover, our approach correctly predicts an effective viscosity enhancement (reduction), as reported experimentally for puller (pusher) microorganisms.

description: Accretion disks play an important role in the evolution of their relativistic inner compact objects. The emergence of a new generation of interferometers will allow to resolve these accretion disks and provide more information about the properties of the central gravitating object. Due to this instrumental leap forward it is crucial to investigate the accretion disk physics near various types of inner compact objects now to deduce later constraints on the central objects from observations. A possible candidate for the inner object is the boson star. Here, we will try to analyze the differences between accretion structures surrounding boson stars and black holes. We aim at analysing the physics of circular geodesics around boson stars and study simple thick accretion tori (so-called Polish doughnuts) in the vicinity of these stars. We realize a detailed study of the properties of circular geodesics around boson stars. We then perform a parameter study of thick tori with constant angular momentum surrounding boson stars. This is done using the boson star models computed by a code constructed with the spectral solver library KADATH. We demonstrate that all the circular stable orbits are bound. In the case of a constant angular momentum torus, a cusp in the torus surface exists only for boson stars with a strong gravitational scalar field. Moreover, for each inner radius of the disk, the allowed specific angular momentum values lie within a constrained range which depends on the boson star considered. We show that the accretion tori around boson stars have different characteristics than in the vicinity of a black hole. With future instruments it could be possible to use these differences to constrain the nature of compact objects.

description: Neural networks have revolutionised the way we approach problem solving across multiple domains; however, their effective design and efficient use of computational resources is still a challenging task. One of the most important factors influencing this process is model hyperparameters which vary significantly with models and datasets. Recently, there has been an increased focus on automatically tuning these hyperparameters to reduce complexity and to optimise resource utilisation. From traditional human-intuitive tuning methods to random search, grid search, Bayesian optimisation, and evolutionary algorithms, significant advancements have been made in this direction that promise improved performance while using fewer resources. In this article, we propose HyperGE, a two-stage model for automatically tuning hyperparameters driven by grammatical evolution (GE), a bioinspired population-based machine learning algorithm. GE provides an advantage in that it allows users to define their own grammar for generating solutions, making it ideal for defining search spaces across datasets and models. We test HyperGE to fine-tune VGG-19 and ResNet-50 pre-trained networks using three benchmark datasets. We demonstrate that the search space is significantly reduced by a factor of 90% in Stage 2 with fewer number of trials. HyperGE could become an invaluable tool within the deep learning community, allowing practitioners greater freedom when exploring complex problem domains for hyperparameter fine-tuning.

description: Suzette Haden Elgin’s novel Native Tongue (1984) provides a fascinating critique of the ideologies inscribed into patriarchal language and evokes an extremely valuable linguistic and political awareness. This article will examine the liability of the ways the novel revolts against the patriarchal society via the introduction of a gynocentric linguistic intervention. I claim, Elgin’s novel showcases an invaluable instance of how it is possible for women to revolt against the pillars of patriarchy through manipulations at the gestalt and schematic level of language and most specifically, the bodily metaphoric quality of the English. This proposed transformation of the schematic and metaphoric structure of English language is a substantial achievement that has recently gained significance through movements like the Me Too Movement, Reproductive Rights Movement, and many more body-political and gender-informed liberal politics.

description: BACKGROUND: Many factors contribute to the burden of surgical diseases, such as trauma, in sub-Saharan Africa, including a paucity of international funding, a shortage of trained clinicians, and underdeveloped infrastructure. Training surgical providers is one solution that has been proposed to reduce the mortality and morbidity due to these diseases in the region. Kamuzu Central Hospital in Lilongwe, Malawi, in partnership with the University of North Carolina at Chapel Hill, established a general surgery residency program in 2009. The purpose of this study is to evaluate changes in trauma-related mortality following the institution of this residency program. METHODS: We review data related to the burden of noncommunicable and surgical disease in sub-Saharan Africa, as well as access to surgical providers and the shortage of healthcare workers in the region. We perform a literature review of proposals aimed at improving the access to surgical services in sub-Saharan Africa. We then present Malawi-specific data, including economic and health indicators, healthcare structure, access to surgical providers, and trauma-related burden of disease. Finally, to determine the influence of the general surgery residency on trauma related mortality at Kamuzu Central Hospital, we perform a retrospective analysis of patients in the hospital's trauma surveillance database, from 2009 to 2014. A logistic regression model was constructed to compare the odds ratio of in-hospital death. RESULTS: In 2009 there were 3 general surgery residents at KCH; this number increased to eleven residents in 2014. During the period of study, 82,534 patients were recorded into the trauma registry database at KCH; the majority were male (72.1%), and mean age was 23.1 years (SD: 15.7). Trauma volume increased for each of the years under study, with 8725 patients recorded in 2009 and 15,998 patients in 2014. Odds of in-hospital death decreased every year as compared to the referent year, when adjusted for primary injury type (severity); age; and gender. CONCLUSION: While surgical burden of disease in sub-Saharan Africa is a complicated issue, training general surgeons in a resource-poor setting represents an effective intervention to help reduce trauma mortality in the region.

description: Genome sequence alignment is the core of many biological applications. The advancement of sequencing technologies produces a tremendous amount of data, making sequence alignment a critical bottleneck in bioinformatics analysis. The existing hardware accelerators for alignment suffer from limited on-chip memory, costly data movement, and poorly optimized alignment algorithms. They cannot afford to concurrently process the massive amount of data generated by sequencing machines. In this paper, we propose a ReRAM-based accelerator, RAPIDx, using processing in-memory (PIM) for sequence alignment. RAPIDx achieves superior efficiency and performance via software-hardware co-design. First, we propose an adaptive banded parallelism alignment algorithm suitable for PIM architecture. Compared to the original dynamic programming-based alignment, the proposed algorithm significantly reduces the required complexity, data bit width, and memory footprint at the cost of negligible accuracy degradation. Then we propose the efficient PIM architecture that implements the proposed algorithm. The data flow in RAPIDx achieves four-level parallelism and we design an in-situ alignment computation flow in ReRAM, delivering $5.5$-$9.7\times$ efficiency and throughput improvements compared to our previous PIM design, RAPID. The proposed RAPIDx is reconfigurable to serve as a co-processor integrated into existing genome analysis pipeline to boost sequence alignment or edit distance calculation. On short-read alignment, RAPIDx delivers $131.1\times$ and $46.8\times$ throughput improvements over state-of-the-art CPU and GPU libraries, respectively. As compared to ASIC accelerators for long-read alignment, the performance of RAPIDx is $1.8$-$2.9\times$ higher.

description: We present a spatially resolved spectroscopic study for the metal poor HII galaxy J084220+115000 using MEGARA Integral Field Unit observations at the Gran Telescopio Canarias. We estimated the gas metallicity using the direct method for oxygen, nitrogen and helium and found a mean value of 12+$\log$(O/H)=$8.03\pm$0.06, and integrated electron density and temperature of $\sim161$ cm$^{-3}$ and $\sim15400$ K, respectively. The metallicity distribution shows a large range of $Δ$(O/H) = 0.72 dex between the minimum and maximum (7.69$\pm$0.06 and 8.42$\pm$0.05) values, unusual in a dwarf star-forming galaxy. We derived an integrated $\log$(N/O) ratio of $-1.51\pm0.05$ and found that both N/O and O/H correspond to a primary production of metals. Spatially resolved maps indicate that the gas appears to be photoionized by massive stars according to the diagnostic line ratios. Between the possible mechanisms to explain the starburst activity and the large variation of oxygen abundance in this galaxy, our data support a possible scenario where we are witnessing an ongoing interaction triggering multiple star-forming regions localized in two dominant clumps.

description: Bei der Erfassung von Publikationen richtet sich der Blick bislang auf bibliographische, technische und organisatorische Metadaten. Diese werden von gängigen Datenbanken weitestgehend erfasst und zum Austausch stehen standardisierte Austauschformate zur Verfügung.Durch den Prozess der Open-Access-Transformation stellt sich zusätzlich die Frage, wie Kosten zukünftig sich auf Forschungseinrichtungen verteilen. Um hierbei eine Transparenz zu erreichen, bietet es sich an, zusätzlich finanzielle Metadaten zu erfassen. Für diese existiert derzeit noch kein gängiges Metadatenschema. Im Rahmen des Projekts openCost (DFG-Projektnummer 457354095) der Universitätsbibliothek Regensburg gemeinsam mit der Zentralbibliothek des DESY und der Universitätsbibliothek Bielefeld wurde – in Kooperation mit internationalen Partnern (u.a. aus Österreich das Projekt AT2OA²) - ein Metadatenschema entwickelt, um Kostendaten standardisiert zum maschinellen und automatisierten Austausch anbieten zu können. Dieses beinhaltet alle Kosten, welche für eine Publikation anfallen unabhängig davon, ob diese mit Open Access in Verbindung stehen oder auch für spezielle Dienstleistung wie etwa Farbabbildung aufgebracht werden müssen. Es umfasst sowohl Zeitschriftenartikel, Bücher als auch Konferenzbeiträge. Ebenso werden Kosten von Transformationsverträge, Comunity-Based-Geschäftsmodellen (Open Library of Humanities, SciPost…), Konsortien (SCOAP³) etc. abgebildet. Eine Berechnung eines Preises pro Publikation ist hier ebenso wünschenswert. Eine erste mögliche Kostenkalkulation wird vorgestellt.Im Rahmen des Vortrags wird das erarbeitete Metadatenschema präsentiert. Dabei wird vertieft auf die Auswahl der einzelnen Felder und die Gedanken sowie die Diskussion, welche zu den Feldern geführt hat, eingegangen. Die daraus resultierende XML-Darstellung wird vorgestellt sowie die erste Implementierung der Aufnahme der Metadaten in ein institutionelles Repositorium, die Bepreisung von einzelnen Publikationen aus Transformationsverträgen und des XML-Outputs gezeigt.
HIV Education in U.S. Prisons: A Recommendation for Programs and Evaluations

description: This paper recommends a minimum standard for program and evaluation plans to address HIV prevalence in U.S. state prisons for male inmates that can be adopted nationally or tailored at the state level. HIV in this group is roughly four times that of the general population. This program is based on relevant public health theories, as well as previous interventions that have successfully improved HIV knowledge in prisons. The program is aimed at increasing HIV knowledge and prevention strategies to inmates through use of peer educators and HIV education sessions. Prison staff, including corrections officers, are provided job training to increase HIV knowledge. Stigma about the virus and reduction of risky behaviors are targeted through use of health behavior change theories to guide educational components. Potential impacts include reduction of HIV transmission in prison and improved population health, particularly in communities at highest risk of being incarcerated.

description: Partial polarization is the manifestation of the correlation between two mutually orthogonal transverse field components associated with a light beam. We show both theoretically and experimentally that the origin of this correlation can be purely quantum mechanical. We perform a two-path first-order (single photon) interference experiment and demonstrate that the degree of polarization of the light emerging from the output of the interferometer depends on path distinguishability. We use two independent methods to control the distinguishability of the photon paths. While the distinguishability introduced in one of the methods can be erased by performing a suitable measurement on the superposed beam, the distinguishability introduced in the other method cannot be erased. We show that the beam is partially polarized only when both types of distinguishability exist. Our main result is the dependence of the degree of polarization on the inerasable distinguishability, which cannot be explained by the classical (non-quantum) theory of light.
