description: Research is increasingly computational, data-driven, and collaborative.
 The increasing size of digital research data that are generated or collected in almost every research project requires us to be more responsible, proactive data managers.
 We are faced with the challenge of not only managing and documenting these data, but also preserving them and making them available for reuse.
 In addition, more and more automated (analysis) pipelines are playing a role in modern research. Therefore, code management is becoming more and more essential in research to ensure the reproducibility of results, as it allows for the systematic organization, version control, and sharing of the software and algorithms. While data and code management can sound like a lot of work for little payoff, managing our research data well actually provides a lot of personal and practical benefits. Well managed and well described data is easier to sort through, access, and understand, making our research project more efficient. Data Management protects against data loss and - increasingly important - publication retractions, possibly sparing you a frustrating experience. This workshop will focused on best practices for managing digital research data.

description: The dynamical evolution of the refractive index of the tensor modes of the geometry produces a specific class of power spectra characterized by a blue (i.e. slightly increasing) slope which is directly determined by the competition of the slow-roll parameter and of the rate of variation of the refractive index. Throughout the conventional stages of the inflationary and post-inflationary evolution, the microwave background anisotropies measurements, the pulsar timing limits and the big-bang nucleosythesis constraints set stringent bounds on the refractive index and on its rate of variation. Within the physically allowed region of the parameter space the cosmic background of relic gravitons leads to a potentially large signal for the ground based detectors (in their advanced version) and for the proposed space-borne interferometers. Conversely, the lack of direct detection of the signal will set a qualitatively new bound on the dynamical variation of the refractive index.

Longitudinal mode-coupling instabilities of proton bunches in the CERN Super Proton Synchrotron
Creators: name: Karpov, Ivan
Publisher: name: arXiv
Year: 2022
Subjects: subject: Accelerator Physics (physics.acc-ph)
subject: FOS: Physical sciences

description: In this paper, we study single-bunch instabilities observed in the CERN Super Proton Synchrotron (SPS). According to the linearized Vlasov theory, radial or azimuthal mode-coupling instabilities result from a coupling of bunch-oscillation modes, which belong to either the same or adjacent azimuthal modes, respectively. We show that both instability mechanisms exist in the SPS by applying the Oide-Yokoya approach to compute van Kampen modes for the realistic longitudinal impedance model of the SPS. The results agree with macroparticle simulations and are consistent with beam measurements. In particular, we see that the uncontrolled longitudinal emittance blow-up of single bunches observed before the recent impedance reduction campaign (2018-2021) is due to the radial mode-coupling instability. Unexpectedly, this instability is as strong as the azimuthal mode-coupling instability, which is possible in the SPS for other combinations of bunch length and intensity. We also demonstrate the significant role of rf nonlinearity and potential-well distortion in determining these instability thresholds. Finally, we discuss the effect of the recent impedance reduction campaign on beam stability in single- and double-rf configurations.

description: Study of current controlled systems and scientific publications has shown that the architecture of controlled systems, related to the products conversion is based on the principle of austerity and, in general, does not provide the possibility of implementing a full parametric optimization. The paper proposes to develop a controlled conversion system from highly specialized systems, each of which performs only one function. The conversion system has the ability of independent conversion process rate control, and finished products are transferred to the buffering system, which provides release of finished products with specified consumer properties and in the required volume to the consumption system. Herewith, the maximum number of degrees of freedom, which is a prerequisite for the implementation of the full parametric optimization is ensured. The product conversion system structure was synthesized based on the liquid portion heating system is synthesized. The system is presented in the form of interconnected simple mechanisms. It is experimentally found that systems with continuous feed - release of raw product are a special case of fully controllable systems with the architecture that provides the optimal control possibility. The developed models were tested and examined in specially designed free software constructor EFFLI. Link to the current model of the controlled system is available in the text.

Off-resonant modulated driving gate protocols for two-photon ground-Rydberg transition and finite Rydberg blockade strength
Creators: name: Sun, Yuan
Publisher: name: arXiv
Year: 2022
Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: Recently, the notion of two-qubit controlled phase gate via off-resonant modulated driving has been introduced into the neutral atom qubit platform, with respect to both single-photon and two-photon ground-Rydberg transitions. In order to reach a better performance practically, further developments are in need to overcome a few known limitations in previous discussions of this promising method. Here, we thoroughly analyze a variety of modulation styles for two-photon transitions, demonstrating the versatility of off-resonant modulated driving protocols. Furthermore, we show that it is possible to refine the designing process for improved performances for specific finite Rydberg blockade strength values. In particular, a reduced requirement on the blockade strength can be directly linked to an improvement of connectivity in qubit array of neutral atoms. These progress are closely related to the core feature that the atomic wave function acquires a geometric phase from the time evolution, which begins and finishes at the same quantum state. Under reasonable experimental conditions readily available nowadays, we anticipate that the fidelity of such protocols can reach as high as the essential requirement of NISQ even if the effects of technical errors and cold atoms' nonzero temperatures are considered.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Objective: To examine the intensity and amount of care at the end of life given to elderly patients at a tertiary academic medial center. Methods: Review of a decedent care database that contains basic information on all deaths occurring at its associated academic medical center. Data was examined for deaths of patients 55 and older that occurred between July 1, 2000 and March 31, 2002. Data related to specific location of death were reclassified into the categories "ICU" and "Floor," and data related to the specific service on which death occurred were reclassified into the categories "Medical" and "Surgical. " Essential demographic information including gender, race, and service were analyzed for all patients. Location of death was analyzed as a proxy variable for intensity of care received at the end of life, and length of stay before death was analyzed as a proxy variable for the amount of care received at the end of life. Analyses were performed using the age categories of 55-65, 65-75, 75-85, and >85 years of age. Results: There were no statistically significant differences in gender, race and service among the different age categories of patients at the end of life. There were statistically significant differences in location of death with increasing age of patients (Age 55-65: 64% ICU, 36% Floor; Age 65-75: 58% ICU, 42% Floor; Age 75-85.· 49% JCU, 51% Floor, Age >85: 41% ICU, 59% Floor). These differences remained statistically significant after controlling for gender, race and service (p<O. 001) When location of death was stratified by service, the differences in location of death remained statistically significant/or deaths occurring on a medical service (p<0.001) but not for deaths occurring on a surgical service (p~0.378) although patients on a surgical service still tended to die outside of the JCU as age increased There were also statistically significant differences in length of stay before death with increasing age of patients (Age 55-65: mean 13.0 days (95% CI 11.1, 14. 9); Age 65-75: 14.5 (12.8, 16.7); Age 75-85: 17.9 (10.0, 13.8); Age >85. 7.2 (4.0, 104)) These differences remained statistically significant after controlling for gender, race, location and service (p~0.001). When stratified by location, the differences in length of stay before death remained statistically significant for both deaths occurring in the ICU (p<0.05) and deaths occurring outside the ICU (p~0.05). Conclusions: At a major tertiary academic medical center, older patients are less likely to receive end-of-life care equal in intensity or amount to the care received by younger patients.

Retrieving refractive index of single spheres using the phase spectrum of light-scattering pattern

description: We analyzed the behavior of the complex Fourier spectrum of the angle-resolved light scattering pattern (LSP) of a sphere in the framework of the Wentzel-Kramers-Brillouin (WKB) approximation. Specifically, we showed that the phase value at the main peak of the amplitude spectrum almost quadratically depends on the particle refractive index, which was confirmed by numerical simulations using both the WKB approximation and the rigorous Lorenz-Mie theory. Based on these results, we constructed a method for characterizing polystyrene beads using the main peak position and the phase value at this point. We tested the method both on noisy synthetic LSPs and on the real data measured with the scanning flow cytometer. In both cases, the spectral method was consistent with the reference non-linear regression one. The former method leads to comparable errors in retrieved particle characteristics but is 300 times faster than the latter one. The only drawback of the spectral method is a limited operational range of particle characteristics that need to be set a priori due to phase wrapping. Thus, its main application niche is fast and precise characterization of spheres with small variation range of characteristics.

description: The metallicity distributions of globular cluster (GC) systems in galaxies are a critical test of any GC formation scenario. In this work, we investigate the predicted GC metallicity distributions of galaxies in the MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE (E-MOSAICS) simulation of a representative cosmological volume ($L = 34.4$ comoving Mpc). We find that the predicted GC metallicity distributions and median metallicities from the fiducial E-MOSAICS GC formation model agree well the observed distributions, except for galaxies with masses $M_\ast \sim 2 \times 10^{10}$ M$_\odot$, which contain an overabundance of metal-rich GCs. The predicted fraction of galaxies with bimodal GC metallicity distributions ($37 \pm 2$ per cent in total; $45 \pm 7$ per cent for $M_\ast > 10^{10.5}$ M$_\odot$) is in good agreement with observed fractions ($44^{+10}_{-9}$ per cent), as are the mean metallicities of the metal-poor and metal-rich peaks. We show that, for massive galaxies ($M_\ast > 10^{10}$ M$_\odot$), bimodal GC distributions primarily occur as a result of cluster disruption from initially-unimodal distributions, rather than as a result of cluster formation processes. Based on the distribution of field stars with GC-like abundances in the Milky Way, we suggest that the bimodal GC metallicity distribution of Milky Way GCs also occurred as a result of cluster disruption, rather than formation processes. We conclude that separate formation processes are not required to explain metal-poor and metal-rich GCs, and that GCs can be considered as the surviving analogues of young massive star clusters that are readily observed to form in the local Universe today.

description: Recent radio-frequency probes, with the ATCA and ASKAP telescopes, have proven themselves to be at the forefront of placing indirect limits on the properties of dark matter. The latter being able to substantially exceed the constraining power of Fermi-LAT data. However, these observations were based only on dwarf galaxies, where magnetic field uncertainties are large. Here we re-examine the case for galaxy clusters, often ignored due to substantial diffuse radio backgrounds, by considering the extrapolation of known cluster surface brightness profiles down to scales observable with MeerKAT. Despite large baryonic backgrounds, we find that clusters can be competitive with dwarf galaxies. Extrapolated Coma data being able to rule out WIMPs of mass $< 700$ GeV annihilating via $b$-quarks. This is while having lesser uncertainties surrounding the magnetic field and diffusive environment. Such compelling results are possible due to a clash between the inner shape of the dark matter halo and the flat inner profile of radio halos which is most pronounced for NFW-like Einasto profiles, the presence of which having some supporting evidence in the literature.

Biopsy in Renal Cell Carcinoma
Creators: name: Vukina, Josip
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Surveillance Epidemiology and End Results (SEER) estimates that 58,240 people will be diagnosed with cancer of the kidney and renal pelvis, while 13,040 will die in 2010. Renal cell cancer accounts for about two percent of all adult cancers. More than 80% of cancers of the kidney arise in the renal parenchyma, while the rest arise in the pelvis. Historically, renal cell carcinoma (RCC) has been treated with nephrectomy, often with no tissue diagnosis, because of the adverse effects and possibility of false negatives associated with renal mass biopsy. With the advancement of imaging modalities in the last decades, smaller tumors are now being discovered that pose therapeutic dilemmas that did not exist in the past. Growing numbers of studies are showing a substantial proportion of these masses is benign on nephrectomy pathology leading urologists to question the current paradigm and reconsider biopsy. Due to improved sampling techniques and advances in immunohistochemistry, recent studies have reported higher levels of sensitivity and specificity for biopsy than were previously reported in the literature. If biopsy could be proven to be dependable, options such as active surveillance and ablative therapies could provide physicians and patients with better choices if patients are not good surgical candidates.

description: The three-dimensional (3D) Fitzhugh-Nagumo neuron model with inertia was shown to exhibit a chaotic mixed-mode dynamics composed of large-amplitude spikes separated by an irregular number of small-amplitude chaotic oscillations. In contrast to the standard 2D Fitzhugh-Nagumo model driven by noise, the interspike-intervals distribution displays a complex arrangement of sharp peaks related to the unstable periodic orbits of the chaotic attractor. For many ranges of parameters controlling the excitability of the system, we observe that chaotic mixed-mode states consist of lapses of nearly regular spiking interleaved by others of highly irregular one. We explore here the emergence of these structures and show their correspondence to the intermittent transitions to chaos. In fact, the average residence time in the nearly-periodic firing state, obeys the same scaling law -- as a function of the control parameter -- than the one at the onset type I intermittency for dynamical systems in the vicinity of a saddle node bifurcation. We hypothesize that this scenario is also present in a variety of slow-fast neuron models characterized by the coexistence of a two-dimensional fast manifold and a one-dimensional slow one.

description: We present a ray tracing code to compute integrated cosmological observables on the fly in AMR N-body simulations. Unlike conventional ray tracing techniques, our code takes full advantage of the time and spatial resolution attained by the N-body simulation by computing the integrals along the line of sight on a cell-by-cell basis through the AMR simulation grid. Moroever, since it runs on the fly in the N-body run, our code can produce maps of the desired observables without storing large (or any) amounts of data for post-processing. We implemented our routines in the RAMSES N-body code and tested the implementation using an example of weak lensing simulation. We analyse basic statistics of lensing convergence maps and find good agreement with semi-analytical methods. The ray tracing methodology presented here can be used in several cosmological analysis such as Sunyaev-Zel'dovich and integrated Sachs-Wolfe effect studies as well as modified gravity. Our code can also be used in cross-checks of the more conventional methods, which can be important in tests of theory systematics in preparation for upcoming large scale structure surveys.

Wer das Buch gelesen hat, dem wird verständlich, dass die Unfähigkeit der Gesellschaft, die zunehmende Last der Schwerkranken zu bewältigen, der zentrale Grund aller Legalisierungsversuche ist. Häufig wünschen nicht die Schwerkranken selbst, sondern wir ihren beschleunigten Tod. Sterbehilfe geht daher uns alle an, und wir tun gut daran, unsere eigenen Vorstellungen aus gesunder Perspektive nicht auf Menschen zu übertragen, die an schweren Krankheiten leiden.

Hospital Infection Rates: Another Score on the Healthcare Provider Report Card
Creators: name: Brown, Vickie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: Purpose: This paper examines the evolving policy of publicly reported hospital infection rates as an indicator of provider quality. Policy: The purpose of health care provider quality report cards is to provide consumers and large purchaser groups with information regarding the quality of patient care. . Policy makers believe that publicly reporting quality indicators will improve the delivery of care, reduce medical errors, decrease costs, improve patient outcomes, and allow consumers informed choice. Recently, hospital infection rates have been identified as an important indicator of quality that should be included in the healthcare provider quality report card. As of November 2005 twelve states have passed legislation related to the public reporting of hospital infection rates. This legislative action has taken place in the absence of an infection surveillance and reporting system that allows for accurate and reliable comparisons of individual hospitals within states and across regions. Current surveillance systems that are based upon administrative data sources or CDC-based surveillance methodology are inadequate due to a lack of sensitivity, specificity and the ability for risk adjustment of patient populations. It is not known what effect, if any, publicly reported hospital-acquired infections will have on patient outcomes.
Rate and Noise-Induced Tipping Working in Concert

description: Rate-induced tipping occurs when a ramp parameter changes rapidly enough to cause the system to tip between co-existing, attracting states. We show that the addition of noise to the system can cause it to tip well below the critical rate at which rate-induced tipping would occur. Moreover it does so with significantly increased probability over the noise acting alone. We achieve this by finding a global minimizer in a canonical problem of the Freidlin-Wentzell action functional of large deviation theory that represents the most probable path for tipping. This is realized as a heteroclinic connection for the Euler-Lagrange system associated with the Freidlin-Wentzell action and we find it exists for all rates less than or equal to the critical rate. Its role as most probable path is corroborated by direct Monte Carlo simulations.

The Public Health Impact of Hydraulic Fracturing

description: Abstract: In recent years, hydraulic fracturing has become a controversial political issue in the United States. Proponents claim that the process, when done safely, can have substantial economic benefits for both the areas surrounding a well and the United States in general. It has also been claimed that hydraulic fracturing has fewer negative health effects on the public’s health and the environment than current methods for producing other energy sources such as coal. Opponents claim that there are myriad public health risks and no safe process for byproduct disposal. Hydraulic fracturing occurs when large quantities of water and chemicals are injected into rock formations to release naturally occurring oil and gas. Though the process has been used for years, it has recently seen an increase due to advances in the technology and the advent of horizontal drilling. Although this new technology makes hydraulic fracturing much more economically efficient for the oil and gas companies, many questions surround the process, including the impact on public health of surrounding communities. Air and water quality are impacted by the chemicals used in hydraulic fracturing, as well as the practice of drilling. Chemicals, including a variety of known carcinogens and radon are released as a result of the process. There are secondary concerns pertaining to occupational exposure and possible earthquake causation. This paper presents an overview of hydraulic fracturing; the public health risks posed by the process and possible mitigation strategies that could reduce those risks. Also presented are recommendations for further research and the need for increased transparency of oil companies, improved assessment of the chemicals used and where the greatest risk occurs in relation to distance from a well. Also needed is new research on the effects of fracking, both the long term health effects and the effect on the community. Finally, the need for enhanced regulatory standards and legislative actions are shown. One of the key recommendations of this paper is that environmental public health must be better represented at the local, state, and national levels when fracking practices are reviewed.

description: We aim to directly trace the vertical location of the emitting surface of multiple molecular tracers in protoplanetary disks. Our sample of disks includes Elias 2-27, WaOph 6 and the sources targeted by the MAPS ALMA Large Program. The set of molecules studied include CO isotopologues in various transitions, HCN, CN, H2CO, HCO+, C2H and c-C3H2. The vertical emitting region is determined directly from the channel maps, implementing accurate masking of the channel emission to recover the vertical location of the emission surface even at large radial distances from the star and for low-SNR lines. The vertical location of the emitting layer is obtained for 4-10 lines in each disk. IM Lup, HD163296 and MWC 480 12CO and 13CO show vertical modulations, which are coincident with dust gaps and kinematical perturbations. We also present estimates of the gas pressure scale height in the disks from the MAPS sample. Compared to physical-chemical models we find good agreement with the vertical location of CO isotopologues. In HD 163296 CN and HCN trace a similar intermediate layer, for the other disks, the UV flux tracers and the vertical profiles of HCN and C2H are lower than predicted in theoretical models. HCN and H2CO show a highly structured vertical profile, possibly indicative of different formation pathways. It is possible to trace the vertical locations of multiple molecular species that trace a wide variety of physical and chemical disk properties. The distribution of CO isotopologues are found at a wide range of vertical heights $z/r = $ 0.5-0.05. Other molecular lines are mostly found at $z/r \leq $0.15. The vertical layering of molecules is in agreement with theory in some systems, but not in all, therefore dedicated chemical-physical models are needed to further study and understand the emission surfaces.

description: We present dynamic spectra from the LWA1 telescope of two large meteors (fireballs) observed to emit between 37 and 54 MHz. These spectra show the first ever recorded broadband measurements of this newly discovered VHF emission. The spectra show that the emission is smooth and steep, getting very bright at lower frequencies. We suggest that this signal is possibly emission of Langmuir waves and that these waves could be excited by a weak electron beam within the trail. The spectra of one fireball displays broadband temporal frequency sweeps. We suggest that these sweeps are evidence of individual expanding clumps of emitting plasma. While some of these proposed clumps may have formed at the very beginning of the fireball event, others must have formed seconds after the initial event.

description: We map the distribution of unpolarized quarks inside a unpolarized pion as a function of the quark's transverse momentum, encoded in unpolarized Transverse Momentum Distributions (TMDs). We extract the pion TMDs from available data of unpolarized pion-nucleus Drell-Yan processes, where the cross section is differential in the lepton-pair transverse momentum. In the cross section, pion TMDs are convoluted with nucleon TMDs that we consistently take from our previous studies. We obtain a fairly good agreement with data. We present also predictions for pion-nucleus scattering that is being measured by the COMPASS Collaboration.

description: Context: The US Armed Forces are experiencing a greatly increased operational tempo due to ongoing military actions around the world. The effects of service members' service component (active or reserve) on post-deployment health risk behaviors and quality of life have not been well characterized. Objective: To compare post-deployment health risk behaviors and health-related quality of life (QOL) among active and reserve component veterans of ongoing military actions. Design: Cross-sectional study based on secondary analysis of data from VA's outpatient Survey of Healthcare Experiences of Patients (SHEP). Setting: Survey mailed monthly to a stratified random sample of veterans who received outpatient care at VA facilities in FY2005. Participants: Outpatients with confirmed deployment in support of Operation Enduring Freedom (OEF) and/or Operation Iraqi Freedom (OIF) (n=7,156). Measures: Demographic patient characteristics, AUDIT -C (alcohol use), smoking status, estimated BMI, SF-12 MCS (mental) and PCS (physical) QOL scales. Results: In unadjusted analyses, active component members were more likely to report binge drinking (p=0.008), healthy BMI (p< 0.001) or obese BMI (p=0.04). These differences disappeared after adjusting for covariates. In adjusted analyses, reserve component members were more likely to report a lifetime history of smoking > 100 cigarettes (p=0.02). Adjusted mean BMI (p=0.03) and SF-12 MCS (p=0.007) were slightly higher for active component members. Conclusions: Service category was not associated with post-deployment health risk behaviors after controlling for demographic covariates. Statistically significant differences in BMI and mental well-being were small and not clinically meaningful. Health risk behaviors are highly prevalent in this post-deployment population, and mental and physical well-being scores are below national means.

description: Upcoming Lepton Flavour Violation experiments searching for $μ\rightarrow 3e$ and $μ$ to $ e $ conversion in nuclei processes will provide new opportunities to test the fundamental properties of the neutrino sector, and possibly the origin of matter. In recent work, it was shown that the Type II Seesaw mechanism alone can simultaneously explain the neutrino masses, Leptogenesis, and inflation. A key prediction of this model was the possibility of signals being produced in Lepton Flavour Violation decays. Searches at future experiments such as Mu3e and COMET will be integral to determining the properties of the associated triplet Higgs, and will complement other terrestrial experimental searches and cosmological measurements. In this work, we survey the detection prospects for the ingredients of the Type II Seesaw Leptogenesis scenario, and discuss the corresponding dependencies on the neutrino oscillation parameters and $\mathcal{CP}$ phases.
