description: The circular photon drag effect is observed in a bulk semiconductor. The photocurrent caused by a transfer of both translational and angular momenta of light to charge carriers is detected in tellurium in the mid-infrared frequency range. Dependencies of the photocurrent on the light polarization and on the incidence angle agree with the symmetry analysis of the circular photon drag effect. Microscopic models of the effect are developed for both intra- and inter-subband optical absorption in the valence band of tellurium. The shift contribution to the circular photon drag current is calculated. An observed decrease of the circular photon drag current with increase of the photon energy is explained by the theory for inter-subband optical transitions. Theoretical estimates of the circular photon drag current agree with the experimental data.

description: Differential conductance spectroscopy performed in the high bias regime -- in which the applied voltage exceeds the sample work function -- is a poor measure of the local density of states due to the effects of the changing tunnel barrier. Additionally, the large applied voltage oftentimes makes constant-height measurement experimentally impractical, lending constant-current spectroscopy an advantageous edge; but the differential conductance in that case is even further removed from the local density of states due to the changing tip height. Here, we present a normalization scheme for extracting the local density of states from high bias scanning tunneling spectroscopy, obtained in either constant-current or constant-height mode. We extend this model to account for the effects of the in-plane momentum of the probed states to the overall current. We demonstrate the validity of the proposed scheme by applying it to laterally confined field-emission resonances, which appear as peak-shaped spectroscopic features with a well-defined in-plane momentum.

Nucleon Resonances Near 2 GeV

description: The nucleon resonances near 2 GeV are investigated through the $Σ$(1385) and $Λ(1520)$ photoproductions within a Regge-plus-resonance approach based on the new experimental data released by the CLAS Collaboration. The $Δ(2000)$ and the $N(2120)$ are found essential to reproduce the experimental data and should be assigned as second $[Δ5/2^+]$ and third $[N3/2^-]$ in the constituent quark model, respectively. A calculation of the binding energy and decay pattern supports that the $N(1875)$, which is listed in the PDG as the third $N3/2^-$ nucleon resonance instead of the $N(2120)$, is from the $Σ(1385)K$ interaction rather than a three quark state.

description: In spectra of the Active Galactic Nuclei (AGNs), the [N II] 6548, 6583 A lines are commonly fitted using the fixed intensity ratio of these two lines (R[N II]=I$_{6583}$/I$_{6548}$). However, the used values for fixed intensity ratio are slightly different through literature. There are several theoretical calculations of the transition probabilities which can be used for the line ratio estimation, but there are no experimental measurements of this ratio, since the [N II] lines are extremely weak in laboratory plasma. Therefore, the intensity ratio of [N II] lines can be measured only in the spectra of astrophysical objects. However, precise and systematic measurements have not be done so far, because of difficulties in measurement of the [N II] ratio in various spectra (overlapping with H$α$, weak intensity of [N II], influence of the continuum noise and outflow contribution, etc.). Here we present the measurements of the flux ratio of the [N II]$λλ$ 6548, 6583 A emission lines for a sample of 250 Type 2 AGNs spectra taken form Sloan Digital Sky Survey (SDSS) data base. The spectra are chosen to have high signal-to-noise ratio and to [N II] and H$α$ lines do not overlap. The obtained mean flux ratio from measurements is 3.049 $\pm$ 0.021. Our result is in agreement with theoretical result obtained by taking into account the relativistic corrections to the magnetic dipole operator.

Sensitivities and correlations of nuclear structure observables emerging from chiral interactions

Publisher: name: arXiv
Year: 2016
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Starting from a set of different two- and three-nucleon interactions from chiral effective field theory, we use the importance-truncated no-core shell model for ab initio calculations of excitation energies as well as electric quadrupole (E2) and magnetic dipole (M1) moments and transition strengths for selected p-shell nuclei. We explore the sensitivity of the excitation energies to the chiral interactions as a first step towards and systematic uncertainty propagation from chiral inputs to nuclear structure observables. The uncertainty band spanned by the different chiral interactions is typically in agreement with experimental excitation energies, but we also identify observables with notable discrepancies beyond the theoretical uncertainty that reveal insufficiencies in the chiral interactions. For electromagnetic observables we identify correlations among pairs of E2 or M1 observables based on the ab initio calculations for the different interactions. We find extremely robust correlations for E2 observables and illustrate how these correlations can be used to predict one observable based on an experimental datum for the second observable. In this way we circumvent convergence issues and arrive at far more accurate results than any direct ab initio calculation. A prime example for this approach is the quadrupole moment of the first 2^+ state in C-12, which is predicted with an drastically improved accuracy.

description: An approximate analytical solution of the Balitsky-Kovchegov (BK) equation using the homotopy perturbation method (HPM) is suggested in this work. We have carried out our work in perturbative QCD (pQCD) dipole picture of deep inelastic scattering (DIS). The BK equation in momentum space with some change of variables and truncation of the BFKL (Balitsky-Fadin-Kuraev-Lipatov) kernel can be reduced to the FKPP (Fisher-Kolmogorov-Petrovsky-Piscounov) equation [Munier and Peschanski 2003]. The observed geometric scaling phenomena are similar to the travelling wave solution of the FKPP equation. We solved the BK equation using the HPM. The obtained solution in this work also suggests the travelling wave nature of the measured scattering amplitude N(k, Y) plotted at various rapidities. The result obtained in this work can be helpful for different phenomenological studies in high-density QCD.

description: We present ALMA observations of the largest protoplanetary disk in the Orion Nebula, 114-426. Detectable 345 GHz (856 micron) dust continuum is produced only in the 350 AU central region of the ~1000 AU diameter silhouette seen against the bright H-alpha background in HST images. Assuming optically thin dust emission at 345 GHz, a gas-to-dust ratio of 100, and a grain temperature of 20 K, the disk gas-mass is estimated to be 3.1 +/- 0.6 Jupiter masses. If most solids and ices have have been incorporated into large grains, however, this value is a lower limit. The disk is not detected in dense-gas tracers such as HCO+ J=4-3, HCN J=4-3, or CS =7-6. These results may indicate that the 114-426 disk is evolved and depleted in some light organic compounds found in molecular clouds. The CO J=3-2 line is seen in absorption against the bright 50 to 80 K background of the Orion A molecular cloud over the full spatial extent and a little beyond the dust continuum emission. The CO absorption reaches a depth of 27 K below the background CO emission at VLSR ~6.7 km/s about 0.52 arcseconds (210 AU) northeast and 12 K below the background CO emission at VLSR ~ 9.7 km/s about 0.34 arcseconds (140 AU) southwest of the suspected location of the central star, implying that the embedded star has a mass less than 1 Solar mass .

Analysis of Medication Errors in the Pediatric Population: Assessment of Age, Error Types, Time to Error Discovery, and Clinical Severity
Creators: name: Louie, Gregory B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Context: Medication errors are a significant source of iatrogenic morbidity and mortality in the hospital inpatient setting. The pediatric population is especially vulnerable to medication errors because of the need to dose medications by weight and their inability to control and understand their medical condition. There are currently few epidemiological studies regarding medication errors in the pediatric inpatient setting. Objectives: To determine 1) the relationship between certain error types and the pediatric age at which these errors occur, 2) the relationship between the time to discovering medication errors and the pediatric age at which these errors occur, and 3) to integrate these findings into a model to determine if age is an independent predictor of clinical severity. Design: Quantitative analysis of database of self-reported medication errors spanning 2 years from February 2000 to May 2002 at the University of North Carolina. Results: We reviewed 6247 medication error reports classified into one of 16 error types. We discovered that certain error types involving incorrect IV/TPN solutions, incorrect IV/TPN rate, and IV incompatibility occurred in a significantly younger age population, and that other error types such as allergy due to medication and medications given at an incorrect time or frequency occurred in a significantly older age population. Younger patients on average experienced errors discovered during the same shift than older patients. Age was found to be an independent predictor of clinical severity in a limited regression model. Conclusions: Age is a significant predictor of medication errors regarding certain clinical error types, time to discovery, and clinical severity.
Unsteadiness characterisation of shock wave/turbulent boundary-layer interaction at moderate Reynolds number

description: A direct numerical simulation of an oblique shock wave impinging on a turbulent boundary layer at Mach number 2.28 is carried out at moderate Reynolds number, simulating flow conditions similar to those of the experiment by Dupont et al. (2006). The low-frequency shock unsteadiness, whose characteristics have been the focus of considerable research efforts, is here investigated via the Morlet wavelet transform. Owing to its compact support in both physical and Fourier spaces, the wavelet transformation makes it possible to track the time evolution of the various scales of the wall-pressure fluctuations. This property also makes it possible to define a local intermittency measure, representing a frequency-dependent flatness factor, to pinpoint the bursts of energy that characterise the shock intermittency scale by scale. As a major result, wavelet decomposition shows that the broadband shock movement is actually the result of a collection of sparse events in time, each characterised by its own temporal scale. This feature is hidden by the classical Fourier analysis, which can only show the time-averaged behaviour. Then, we propose a procedure to process any relevant time series, such as the time history of the wall-pressure or that of the separation bubble extent, in which we use a condition based on the local intermittency measure to filter out the turbulent content in the proximity of the shock foot and to isolate only the intermittent component of the signal. In addition, wavelet analysis reveals the intermittent behaviour also of the breathing motion of the recirculation bubble behind the reflected shock, and allows us to detect a direct, partial correspondence between the most significant intermittent events of the separation region and those of the wall-pressure at the foot of the shock.
Interaction between single vacancies in graphene sheet: An ab initio calculation

description: In order to investigate the interaction between single vacancies in a graphene sheet, we have used spin-polarized density functional theory (DFT). Two distinct configurations were considered, either with the two vacancies located in the same sublattice or in different sublattices, and the effect of changing the separation between the vacancies was also studied. Our results show that the ground state of the system is indeed magnetic, but the presence of the vacancies in the same sublattice or in different sublattices and the possible topological configurations can lead to different contributions from the $π$ and $σ$ orbitals to magnetism. On the other hand, our findings reveal that the net magnetic moment of the system with the two vacancies in the same sublattice move towards the value of the magnetic moment per isolated vacancy with the increase of the distance between the vacancies, which is ascribed to the different contributions due to $π$ electrons. Moreover, it is also found that the local magnetic moments for vacancies in the same sublattice are in parallel configuration, while they have different orientations when the vacancies are created in different sublattices. So, our findings have clearly evidenced how difficult it would be to observe experimentally the emergence of magnetic order in graphene-based systems containing randomly created atomic vacancies, since the energy difference between cases of antiferromagnetic and ferromagnetic order decreases quickly with the increase in the distance separating each vacancy pair.
Clinical decision making in occupational HIV exposure: The role of baseline laboratory testing in the exposed healthcare provider
Creators: name: Ohadugha, Chima
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Objectives We investigated whether baseline laboratory findings change provider prescribing behavior for HIV post-exposure prophylaxis. Methods A retrospective review of occupational health records from a large, tertiary care academic medical center was conducted. Subjects were healthcare providers (HCP) with clinical or research exposure to HIV who completed a 28-day course of once daily tenofovir disoproxil/emtricitabine (245/200 mg) plus twice daily raltegravir (400 mg). Basic demographic information, exposure information and laboratory values were obtained from the medical record. Results Between January 1, 2012, and May 12, 2016, 64 HCP completed a 28-day course of post-exposure prophylaxis (PEP). Two HCP presented with laboratory abnormalities at baseline {renal (1), hepatic (1)} and three HCP had abnormal changes at two weeks compared to baseline {renal (2), hematologic (1)}; however, none of the abnormalities led to modification or discontinuation of PEP. There were no HIV seroconversions throughout the study period. Conclusion Our five-year experience of prescribing PEP at a large academic medical center suggests that baseline assessment of renal, hematologic and hepatic function is unnecessary when starting the HIV post-exposure prophylaxis regimen of tenofovir disoproxil/emtricitabine/raltegravir. Given that HCP are generally a healthy population, that hepatic or renal dose adjustments are not required for this PEP regimen and that this course of PEP is well-tolerated it appears that baseline laboratory testing is unnecessary. Elimination of routine renal, hematologic and hepatic function studies in occupational HIV exposures should be considered as a way to improve the timeliness of starting PEP after exposure as well as eliminate the barrier of seeking immediate care after exposure beyond obtaining PEP medications

description: We consider dense random packing of disks with a power-law distribution of radii and investigate their correlation properties. We study the corresponding structure factor, mass-radius relation and pair distribution function of the disk centers. A toy model of dense segments in one dimension (1d) is solved exactly. It is shown theoretically in 1d and numerically in 1d and 2d that such packing exhibits fractal properties. It is found that the exponent of the power-law distribution and the fractal dimension coincide. An approximate relation for the structure factor in arbitrary dimension is derived, which can be used as a fitting formula in small-angle scattering. The findings can be useful for understanding microstructural properties of various systems like ultra-high performance concrete, high-internal-phase ratio emulsions or biological systems.

description: Accurate phase measurement is highly desirable in optical manipulation driven by structured light, since the phase profiles have a close connection with optical force distribution, strongly affecting the capability of optical traps. Here, we report a novel interferometric phase measurement technique for accurately measuring the phase profiles of structured light in holographic optical trapping system. The related experiments are performed, in which the obtained phase profiles agree well with the designed phase profiles. It reveals that the phase profiles of structured light can be accurately obtained. Importantly, the fast switch between phase measurement and optical manipulation experiment can be easily realized, which are strongly preferable in optical trapping system. This study offers a promising way for accurately obtaining phase profiles of structure light, which is very helpful for realizing optical trapping with high performance.

In this regard, the study of star formation history (SFH) plays an important role in the accurate understanding of galaxies. In this paper, we used long-period variable stars (LPVs) to estimate the SFH in the Andromeda galaxy (M31). These cool stars reach their peak luminosity in the final stage of their evolution; their birth mass is directly related to their luminosity. Therefore, we construct the mass function and the star formation history using stellar evolution models.

description: Precise temperature measurements on systems of few ultracold atoms is of paramount importance in quantum technologies, but can be very resource-intensive. Here, we put forward an adaptive Bayesian framework that substantially boosts the performance of cold atom temperature estimation. Specifically, we process data from real and simulated release--recapture thermometry experiments on few potassium atoms cooled down to the microkelvin range in an optical tweezer. From simulations, we demonstrate that adaptively choosing the release--recapture times to maximise information gain does substantially reduce the number of measurements needed for the estimate to converge to a final reading. Unlike conventional methods, our proposal systematically avoids capturing and processing uninformative data. We also find that a simpler non-adaptive method exploiting all the a priori information can yield competitive results, and we put it to the test on real experimental data. Furthermore, we are able to produce much more reliable estimates, especially when the measured data are scarce and noisy, and they converge faster to the real temperature in the asymptotic limit. Importantly, the underlying Bayesian framework is not platform-specific and can be adapted to enhance precision in other setups, thus opening new avenues in quantum thermometry.

description: Dynamic Mode Decomposition (DMD) is a model-order reduction approach, whereby spatial modes of fixed temporal frequencies are extracted from numerical or experimental data sets. The DMD low-rank or reduced operator is typically obtained by singular value decomposition of the temporal data sets. For parameter-dependent models, as found in many multi-query applications such as uncertainty quantification or design optimization, the only parametric DMD technique developed was a stacked approach, with data sets at multiples parameter values were aggregated together, increasing the computational work needed to devise low-rank dynamical reduced-order models. In this paper, we present two novel approach to carry out parametric DMD: one based on the interpolation of the reduced-order DMD eigenpair and the other based on the interpolation of the reduced DMD (Koopman) operator. Numerical results are presented for diffusion-dominated nonlinear dynamical problems, including a multiphysics radiative transfer example. All three parametric DMD approaches are compared.

description: Despite increased attention to developing sustainable and scalable public health interventions, the gap between interventions tested in designed experiments and field-based delivery continues to widen. This paper discusses how implementation failures can impede progress in reducing health-related morbidity and mortality, and how to address these program deficiencies through the application of a systematic implementation approach. Research-based interventions are needed to enhance the likelihood of achieving sustainable improvements in population health, but they may fail to achieve desired outcomes if they cannot be adopted in practice. Little guidance in established public health research or practice is offered on how to apply science to a variety of situations and contexts. Consequently, practitioners are unable to determine whether implementation failures are a result of incomplete delivery, lack of evidence to support the theory behind an intervention, resource constraints, failed systems, or a poorly designed program. Developing scalable, well-integrated and high-performing interventions that can thrive amidst disparate environments demands a more systematic approach. To be effective, health initiatives require a deeper understanding of the infrastructure, policies, people and processes that influence implementation. This paper presents an approach to enhance implementation practice through the use of an Implementation Science Framework. The Implementation Science Framework clarifies how established systems improvement techniques such as Lean/Six Sigma and Continuous Quality Improvement can be incorporated into a comprehensive implementation structure through which interventions can be delivered and institutionalized in a variety of settings. The accompanying case study applies the Implementation Science Framework to the development of a tobacco cessation program at a North Carolina Adult Drug and Alcohol Treatment Center. In four project phases, this case study illustrates how methods and tools from the Implementation Science Framework were used towards the goal of achieving sustainable reductions in smoking prevalence. Implementation science is a proven approach to improve the quality and sustainability of public health programs. By strengthening the view that public health delivery is an organic, proactive process that depends on greater awareness of situational barriers and assets, considerable gains could be achieved in improving the efficiency and effectiveness of complex health interventions, and ultimately, the public's health.
A cloud-cloud collision in Sgr B2? 3D simulations meet SiO observations

description: We compare the properties of shocked gas in Sgr B2 with maps obtained from 3D simulations of a collision between two fractal clouds. In agreement with $^{13}$CO(1-0) observations, our simulations show that a cloud-cloud collision produces a region with a highly turbulent density substructure with an average $N_{\rm H2}\gtrsim 5\times10^{22}\,\rm cm^{-2}$. Similarly, our numerical multi-channel shock study shows that colliding clouds are efficient at producing internal shocks with velocities of $5-50\,\rm km\,s^{-1}$ and Mach numbers of $\sim4-40$, which are needed to explain the $\sim 10^{-9}$ SiO abundances inferred from our SiO(2-1) IRAM observations of Sgr B2. Overall, we find that both the density structure and the shocked gas morphology in Sgr B2 are consistent with a $\lesssim 0.5\,\rm Myr$-old cloud-cloud collision. High-velocity shocks are produced during the early stages of the collision and can ignite star formation, while moderate- and low-velocity shocks are important over longer time-scales and can explain the extended SiO emission in Sgr B2.

Worker Health Risk from Energy Drinks
Creators: name: Dennison, Kim
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: ABSTRACT Little research has been done on the effects of energy drinks on workers, and their ingredients as a whole are not well understood. However, the circumstantial evidence has moved medical communities, politicians, parents, and worker health and safety professionals to begin to question their safety. Policies to protect workers are now being instituted by various work sectors but a general lack of awareness could prove catastrophic. New research is now emerging in the occupational health sector that demonstrates a likely link with energy drinks and ill health effects in workers. Occupational and environmental health nurses can develop prevention, intervention, and advocacy programs to assist in preventing the toxic effects of energy drinks among workers.

Subjects: Cell neurochemistry

description: Gallic acid (GA) is a phenolic molecule found naturally in a wide range of fruits as well as in medicinal plants. It has many health benefts due to its antioxidant properties. This study focused on fnding out the neurobiological efects and mechanisms of GA using published data from reputed databases. For this, data were collected from various sources, such as PubMed/Medline, Science Direct, Scopus, Google Scholar, SpringerLink, and Web of Science. The fndings suggest that GA can be used to manage several neurological diseases and disorders, such as Alzheimer’s dis‑ ease, Parkinson’s disease, strokes, sedation, depression, psychosis, neuropathic pain, anxiety, and memory loss, as well as neuroinfammation. According to database reports and this current literature-based study, GA may be considered one of the potential lead compounds to treat neurological diseases and disorders. More preclinical and clinical studies are required to establish GA as a neuroprotective drug

An exact one-particle theory of bosonic excitations: From a generalized Hohenberg-Kohn theorem to convexified N-representability

description: Motivated by the Penrose-Onsager criterion for Bose-Einstein condensation we propose a functional theory for targeting low-lying excitation energies of bosonic quantum systems through the one-particle picture. For this, we employ an extension of the Rayleigh-Ritz variational principle to ensemble states with spectrum $\boldsymbol{w}$ and prove a corresponding generalization of the Hohenberg-Kohn theorem: The underlying one-particle reduced density matrix determines all properties of systems of $N$ identical particles in their $\boldsymbol{w}$-ensemble states. Then, to circumvent the $v$-representability problem common to functional theories, and to deal with energetic degeneracies, we resort to the Levy-Lieb constrained search formalism in combination with an exact convex relaxation. The corresponding bosonic one-body $\boldsymbol{w}$-ensemble $N$-representability problem is solved comprehensively. Remarkably, this reveals a complete hierarchy of bosonic exclusion principle constraints in conceptual analogy to Pauli's exclusion principle for fermions and recently discovered generalizations thereof.

description: We consider the problem for the classification of static and asymptotically flat Einstein-Maxwell-dilaton spacetimes with a photon sphere. It is first proven that the photon spheres in Einstein-Maxwell-dilaton gravity have constant mean and constant scalar curvature. Then we derive some relations between the mean curvature and the physical characteristics of the photon spheres. Using further the symmetries of the dimensionally reduced Einstein-Maxwell-dilaton field equations we show that the lapse function, the electrostatic potential and the dilaton field are functionally dependent in the presence of a photon sphere. Using all this we prove the main classification theorem by explicitly constructing all Einstein-Maxwell-dilaton solutions possessing a non-extremal photon sphere.
