description: We analyze theoretically the phenomenon of electromagnetically induced transparency (EIT) under conditions where the probe laser is not in the usual weak limit. We consider the effects in both three-level and four-level systems, which are either closed or open (due to losses to an external metastable level). We find that the EIT dip almost disappears in a closed three-level system but survives in an open system. In four-level systems, there is a narrow enhanced-absorption peak (EITA) at line center, which has applications as an optical clock. The peak converts to an EIT dip in a closed system, but again survives in an open system.

description: We introduce a procedure to infer the interactions among a set of binary variables, based on their sampled frequencies and pairwise correlations. The algorithm builds the clusters of variables contributing most to the entropy of the inferred Ising model, and rejects the small contributions due to the sampling noise. Our procedure successfully recovers benchmark Ising models even at criticality and in the low temperature phase, and is applied to neurobiological data.

description: Phase change materials (PCMs) have gained a tremendous interest as a means to actively tune nanophotonic devices through the large optical modulation produced by their amorphous to crystalline reversible transition. Recently, materials such as Sb$_2$S$_3$ emerged as particularly promising low loss PCMs, with both large refractive index modulations and transparency in the visible and NIR. Controlling the local and reversible phase transition in this material is of major importance for future applications, and an appealing method to do so is to exploit pulsed lasers. Yet, the physics and limits involved in the optical switching of Sb$_2$S$_3$ are not yet well understood. Here, we investigate the reversible laser-induced phase transition of Sb$_2$S$_3$, focusing specifically on the mechanisms that drive the optically induced amorphization, with multi-physics considerations including the optical and thermal properties of the PCM and its environment. We theoretically and experimentally determine the laser energy threshold for reversibly changing the phase of the PCM, not only between fully amorphous and crystalline states but also between partially recrystallized states. We then reveal the non-negligible impact of the material's polycrystallinity and anisotropy on the power thresholds for optical switching. Finally, we address the challenges related to laser amorphization of thick Sb$_2$S$_3$ layers, as well as strategies to overcome them. These results enable a qualitative and quantitative understanding of the physics behind the optically-induced reversible change of phase in Sb$_2$S$_3$ layers.

description: Thermoelectric power of a material, typically governed by its band structure and carrier density, can be varied by chemical doping that is often restricted by solubility of the dopant. Materials showing large thermoelectric power are useful for many industrial applications, such as the heat-to-electricity conversion and the thermoelectric cooling device. Here we show a full electric field tuning of thermoelectric power in a dual-gated bilayer graphene device resulting from the opening of a band-gap by applying a perpendicular electric field on bilayer graphene. We uncover a large enhancement in thermoelectric power at low temperature, which may open up a new possibility in low temperature thermoelectric application using graphene-based device.

description: Effects of Al, Mn and Sb dopings in CeFe2 and effect of applied pressure have been investigated. Al doping gives rise to the FM-AFM transition and a reduction in the magnetic moment and TC values, clearly indicating the growth of the AFM component. Mn and Sb dopings only cause a reduction in TC value. It is found that in general external pressure enhances the antiferromagnetism in both the pure and the doped alloys. Enhancement of the Ce 4f- Fe 3d hybridization as a result of dopings and with the external pressure may be the reason for the stabilization of antiferromagnetism in these alloys.

description: We report a precise measurement of the hyperfine interval in the ${2P}_{1/2}$ state of $^{7}$Li. The transition from the ground state ($D_1$ line) is accessed using a diode laser and the technique of saturated-absorption spectroscopy in hot Li vapor. The interval is measured by locking an acousto-optic modulator to the frequency difference between the two hyperfine peaks. The measured interval of 92.040(6)~MHz is consistent with an earlier measurement reported by us using an atomic-beam spectrometer [Das and Natarajan, J.\ Phys.\ B {\bf 41}, 035001 (2008)]. The interval yields the magnetic dipole constant in the $P_{1/2}$ state as $A=46.047(3)$, which is discrepant from theoretical calculations by $>80$~kHz.

Several advanced moltemplate examples and code needed to run them

Subjects: coarse-grained-molecular-dynamics, lammps, molecule-builder

description: A collection of files for demonstrating some of the advanced features of the moltemplate coarse-grained molecule builder software for LAMMPS (moltemplate.org). These files are intentionally complicated in order to show off these features. New users are encouraged to visit moltemplate.org where they can find a more gentle introduction to moltemplate. Archive #1 Archive #1 contains several coarse-grained simulation examples. They were selected because they are (currently) only easy to prepare using moltemplate. These examples are files in moltemplate format (LT files). Additional README files and some bash scripts and links are included. Archive #2 These examples take advantage of the extensibility of LAMMPS. LAMMPS is a molecular dynamics program, and moltemplate is a tool for preparing input files for LAMMPS. In order for these complex examples to work, new LAMMPS features were needed (such as twist motors and ellipsoidal bonding). So new code was added to LAMMPS to implement these features. That new code is included, along with the LAMMPS code, moltemplate code, and other auxiliary programs (such as PACKMOL) in archive #2. Revisions As LAMMPS and moltemplate evolve, these examples will be updated in order to make them work on future versions of LAMMPS. Updated moltemplate examples and code can be downloaded at moltemplate.org. Updated LAMMPS code can be found at lammps.sandia.gov. A README file is provided in each archive with more details explaining where to find the most recent versions of these examples and their supporting code.

The Fusion of Material and Symbolic Capital in the American Century
Creators: name: Kelley, Bridget
Publisher: name: University of Notre Dame

description: From Introduction: 'When sharing his vision for America in the 20th century in “The American Century,” publishing magnate Henry Luce argued, “Blindly, unintentionally, accidentally, and really in spite of ourselves, we are already a world power in all the trivial ways – in very human ways” (1). Luce believed that the international dominance of American culture, from movies and music to language and material goods, gave the nation power that was both economically and symbolically important. In the late 19th and early 20th centuries, America lived out Luce’s vision of economic and symbolic capital through material culture. In “The Power of Capital and the Problem of Legitimacy” by nineteenth-century historian Sven Beckert and “Setback Skyscrapers and American Architectural Development” by architecture scholar Benjamin Flowers, we see how the 7th Regiment’s Upper East Side armory and the Empire State Building were fields for Americans to develop social and cultural capital, while also acting as symbols of a wider American cultural cachet. In the realm of consumer goods, Allan Brandt’s “Engineering Consent” demonstrates how cigarettes possessed abundant social and economic meaning, democratizing access to goods while helping America as a whole grow in wealth and stature. The confluence of economic and cultural capital in these spaces and products affected class lines within the United States while contributing to Luce’s vision of an international “American culture” that reflected prestige and upper-class tastes.'

Adaptive ultrasound imaging to improve the visualization of spine and associated structures
Creators: name: Zhuang, Bo
Publisher: name: University of British Columbia
Year: 2018

description: Visualizing vertebrae or other bone structures clearly in ultrasound imaging is important for many clinical applications such as ultrasound-guided spinal needle injections and scoliosis detection. Another growing research topic is fusing ultrasound with other imaging modalities to get the benefit from each modality. In such approaches, tissue with strong interfaces, such as bones, are typically extracted and used as the feature for registration. Among those applications, the spine is of particular interest in this thesis. Although such ultrasound applications are promising, clear visualization of spine structures in ultrasound imaging is difficult due to factors such as specular reflection, off-axis energy and reverberation artifacts. The received channel ultrasound data from the spine are often tilted even after delay correction, resulting in signal cancellation during the beamforming process. Conventional beamformers are not designed to tackle this issue. In this thesis, we propose three beamforming methods dedicated to improve the visualization of spine structures. These methods include an adaptive beamforming method which utilizes the accumulated phase change across the receive aperture as the beamforming weight. Then, we propose a log-Gabor based directional filtering method to regulate the tilted channel data back to the beamforming direction to avoid bone signal cancellation. Finally, we present a closed-loop beamforming method which feeds back the location of the spine to the beamforming process so that backscattered bone signals can be aligned prior-to the beamforming. Field II simulation, phantom and in vivo results confirm significant contrast improvement of spinal structures compared with the conventional delay-and-sum beamforming and other adaptive beamforming methods.

description: The population of $γ$-ray emitting millisecond pulsars (MSPs) is studied by using Monte-Carlo techniques. We simulate the Galactic distributions of the MSPs, and apply the outer gap model for the $γ$-ray emission from each simulated MSP. We take into account the dependence of the observed $γ$-ray flux on the viewing angle and inclination angle, which is the angle between the rotation axis and the magnetic axis, respectively. Using the sensitivity of the six-month long observation of the $Fermi$ telescope and radio sensitivities of existing pulsar surveys, 9-13 radio-selected and 22-35 $γ$-ray-selected pulsars are detected within our simulation. The statistical properties of the simulated population are consistent with the $Fermi$ observations. Scaling the observed sensitivity $\propto \sqrt{T}$, where $T$ is the length of observation time, the present model predicts that over the 5-year mission $Fermi$ would detect 15-22 radio-selected $γ$-ray MSPs, and 95-152 $γ$-ray-selected MSPs. Our simulation also predicts that about 100 (or 200-300) $γ$-ray MSPs with a flux larger $F\ge 10^{-11}~\mathrm{erg/cm^2 s}$ (or $5\times 10^{-12}~\mathrm{erg/cm^2 s}$) irradiate the Earth. With the present sensitivities of the radio surveys, most of them are categorized as $γ$-ray-selected pulsars, indicating that most of the $γ$-ray MSPs have been missed by the present $Fermi$ observations. We argue that the Galactic $Fermi$ unidentified sources located at high latitudes should be dominated by MSPs, whereas the sources in the galactic plane are dominated by radio-quiet canonical pulsars.

description: Polarization wiggling is a direct gravitational effect exerted by a gravitational field on any electromagnetic radiation traversing it. This effect is investigated in linear gravity for spacetimes with flat or conformally flat backgrounds. First, we show how the polarization wiggle rates can be computed in the conformal frame and transformed to the physical frame. Then it is shown that polarization wiggling is not sensitive to scalar perturbations to the metric, while vector and tensor perturbations do induce polarization wiggling. This poses two natural questions: Can polarized electromagnetic radiation be used to measure vectorial and tensorial components of gravitational fields directly? And if so, how? Next, polarization wiggling is studied for an arbitrary vector perturbation to the spacetime metric. In a stationary spacetime, the polarization wiggle rate is proportional to the difference in frame dragging rates between radiation emission and measurement events. We show how this can be used to measure the angular momentum of a gravitational source if the emitter orbits the gravitational source on a known orbit. Next, the effect of a gravitational tensor mode with arbitrary polarization is studied. Finally, the polarization wiggling effect induced by a gravitational tensor mode is analyzed. Two cases are demonstrated: A spacetime with a flat Minkowski background and an expanding cosmology with a conformally flat background. In both cases, the polarization wiggling frequency equals the frequency of the gravitational tensor mode, while the other state parameters are encoded in the polarization wiggling amplitude and phase of the polarized radiation. We show that measurements of polarization wiggling frequency, amplitude and phase of polarized radiation from different directions enables all state parameters of a gravitational tensor mode to be determined.

description: An optical photometric observation in 15 bands was carried out for nearby galaxy cluster Abell 1775 by the Beijing-Arizona-Taiwan-Connecticut (BATC) multi-color system. Over 5000 sources' spectral energy distributions (SEDs) were obtained. Since this cluster has also been observed by the Sloan Digital Sky Survey (SDSS), the BATC SEDs were combined with the SDSS five-band photometric data. Using the combined SEDs, 146 faint galaxies were selected as new member galaxies by the photometric redshift technique. Based on the positions, redshifts and 20-band SEDs of member galaxies, dynamical substructures and luminosity functions (LFs) of A1775 were investigated. The previous reported bimodal structure of A1775 has been confirmed: a poor subcluster with lower redshift, A1775A, is located ~14' southeast to the main concentration A1775B. After taking into account the new supplemented member galaxies, a new subcluster A1775C was found along the aligned direction of A1775A and A1775B. The different LF faint ends of the two subclusters indicate that A1775B is a more dynamically evolved system, while A1775A is still dynamically young. By the STARLIGHT spectral synthesis code, the star- formation histories of the member galaxies were studied. The dependence of the mean stellar ages upon the Hubble type was confirmed, and the environmental effect on star-formation activities for galaxies in A1775B has been explored.

description: Magnetic field and time induced steps have been observed in the recently discovered ternary silicide R6Co1.67Si3. Huge relaxation steps are observed across different loops in the low temperature magnetization isotherms. Giant relaxation present in this system indicates the existence of incubation time to get the saturated moment at a certain field. Measurement protocol sensitive magnetization behavior observed in this system may arise from the strong magnetostructural coupling and/or magnetic frustration. Electrical resistivity and magnetoresistance also reflect the magnetic state of the compound. Magnetocaloric effect is found to be large at temperatures close to the magnetic transition temperature.

description: We generalize the binary quantum counting algorithm of Lesovik, Suslov, and Blatter [Phys. Rev. A 82, 012316 (2010)] to higher counting bases. The algorithm makes use of qubits, qutrits, and qudits to count numbers in a base 2, base 3, or base d representation. In operating the algorithm, the number n < N = d^K is read into a K-qudit register through its interaction with a stream of n particles passing in a nearby wire; this step corresponds to a quantum Fourier transformation from the Hilbert space of particles to the Hilbert space of qudit states. An inverse quantum Fourier transformation provides the number n in the base d representation; the inverse transformation is fully quantum at the level of individual qudits, while a simpler semi-classical version can be used on the level of qudit registers. Combining registers of qubits, qutrits, and qudits, where d is a prime number, with a simpler single-shot measurement allows to find the powers of 2, 3, and other primes d in the number n. We show, that the counting task naturally leads to the shift operation and an algorithm based on the quantum Fourier transformation. We discuss possible implementations of the algorithm using quantum spin-d systems, d-well systems, and their emulation with spin-1/2 or double-well systems. We establish the analogy between our counting algorithm and the phase estimation algorithm and make use of the latter's performance analysis in stabilizing our scheme. Applications embrace a quantum metrological scheme to measure a voltage (analog to digital converter) and a simple procedure to entangle multi-particle states.

description: Les races locales de porcs sont fréquemment élevées dans des systèmes de production extensifs adaptés à l’environnement local et aux ressources disponibles. Ces systèmes sont généralement moins efficaces que les systèmes conventionnels mais produisent des biens publics et services pour la société (biodiversité, qualité de l’air, attractivité du paysage). La fourniture de biens publics peut ne pas être garantie par manque de reconnaissance de leur valeur économique, ou de politiques pouvant fragiliser l’avenir de ces systèmes. Des méthodes d’évaluation économique permettent de mesurer les avantages non marchands fournis par ces systèmes, par une estimation de la demande sociale envers leurs principales caractéristiques. Dans le projet européen TREASURE, une enquête d’expérimentation de choix a été réalisée pour évaluer la demande sociétale pour des caractéristiques spécifiques de la filière régionale française Noir de Bigorre (NdB), basée sur l’élevage en système extensif de porcs de race Gascon. Un questionnaire d’évaluation a été distribué, permettant l’obtention des réponses de 418 personnes, pour moitié localisées dans la région de production de la filière NdB. Les résultats montrent que 40% des répondants ne connaissent ou ne consomment pas les produits issus de cette filière. En moyenne, le consentement à payer le plus élevé est attribué pour garantir la pérennité de la race (112,37 €/foyer/an). Les répondants consentiraient à payer 42,35 € pour maintenir un nombre équivalent d’élevages de taille petite ou moyenne, et 21,86 € pour que les aliments des animaux soient produits à proximité des élevages. La disponibilité géographique et le type de points de vente des produits contribuent de façon moindre à construire leurs préférences. Ces résultats montrent qu’une demande sociale existe pour soutenir la pérennité de la race et un système de production extensif en lien avec des ressources locales.
PREALBUMIN AS A MALNUTRITION INDICATOR IN ELDERLY PATIENTS ADMITTED TO A SKILLED NURSING FACILITY

description: Malnutrition is underdiagnosed in the geriatric population residing in a skilled nursing facility (SNF) and is associated with increased morbidity, hospital readmissions, and multiple complications. Although several screening tools have been developed, malnutrition still is inadequately recognized and managed. A prealbumin level is a potentially useful malnutrition marker and can be used to determine the need for nutritional supplements. This project examined the prevalence of malnutrition and the efficacy of an oral enriched protein supplement in a population of patients in the SNF setting. A retrospective program evaluation of existing data was completed to evaluate the efficacy of an existing treatment plan for those at risk for malnutrition. Existing patient data from four SNFs were screened for eligibility criteria: Data included demographic information, admission prealbumin levels, protocol-based protein supplement received, and a 30-day prealbumin level. Eighty patients were included in the study. Seventy-six percent of the patients had malnutrition (prealbumin <17mg/dl). The median age was 82.6 years, 45% were male. Prealbumin scores of patients at baseline (M = 10.54, SD = 3.52) increased from 30-day follow-up (M = 15.05, SD = 6.36). There was a statistically significant interaction effect for protocol (F (1, 37) = 35.99, p < .001); change in prealbumin scores was dependent on protocol. The protein supplement group (protocol group) had an increase in prealbumin scores from baseline (M = 9.79, SD = 3.23) to 30-day (M = 17.03). Statistical significance was found in an interaction effect for protocol (F (1, 37) = 35.99, p < .001); change in prealbumin scores iv was dependent on protocol. Despite higher initial average prealbumin scores at baseline (non-protocol group), not receiving the oral protein supplements as prescribed, experienced decreases in their prealbumin scores from baseline (M = 12.70, SD = 3.56) to 30-day follow-up (M = 9.30, SD = 15.05). A prealbumin level upon admission at a SNF is a reliable tool to evaluate malnutrition. The use of an oral protein supplement should be considered for patients with existing malnutrition in the SNF, which could prevent further malnutrition and adverse complications.

description: Транскраниальная магнитная стимуляция (ТМС) в последние годы привлекает все большее внимание как метод неинвазивной нейромодуляции с широким спектром потенциальных клинических применений. Технология ТМС базируется на принципе электромагнитной индукции, позволяющем генерировать локальные электрические поля в нервной ткани посредством кратковременных магнитных импульсов без существенного снижения их интенсивности при прохождении через костные структуры черепа. Первоначально используемая как диагностический инструмент для оценки функционального состояния кортикоспинальных путей, ТМС теперь активно исследуется в качестве терапевтического метода при различных неврологических и психиатрических расстройствах.

description: Graphene-based photodetectors are promising new devices for high-speed optoelectronic applications. However, despite recent efforts, it is not clear what determines the ultimate speed limit of these devices. Here, we present measurements of the intrinsic response time of metal-graphene-metal photodetectors with monolayer graphene using an optical correlation technique with ultrashort laser pulses. We obtain a response time of 2.1 ps that is mainly given by the short lifetime of the photogenerated carriers. This time translates into a bandwidth of ~262 GHz. Moreover, we investigate the dependence of the response time on gate voltage and illumination laser power.

description: For the steady-state direct cascade of two-dimensional Navier-Stokes turbulence, we derive analytically the probability of strong vorticity fluctuations. The probability density function (pdf) of the vorticity coarse-grained over a scale in the inertial interval is shown to have a universal self-similar form, in distinction from other known direct cascades. The tails of the pdf are found to be exponential.

description: There is growing evidence of relativistic jets in radio-loud narrow-line Seyfert 1 (RL-NLS1) galaxies. We constrain the observational properties of the radio emission in the first RL-NLS1 galaxy ever detected in gamma-rays, PMN J0948+0022, i.e., its flux density and structure in total intensity and in polarization, its compactness, and variability. We performed three real-time e-VLBI observations of PMN J0948+0022 at 22 GHz, using a global array including telescopes in Europe, East Asia, and Australia. These are the first e-VLBI science observations ever carried out with a global array, reaching a maximum baseline length of 12458 km. The observations were part of a large multiwavelength campaign in 2009. The source is detected at all three epochs. The structure is dominated by a bright component, more compact than 55 microarcsec, with a fainter component at a position angle theta~ 35deg. Relativistic beaming is required by the observed brightness temperature of 3.4x10^11 K. Polarization is detected at a level of about 1%. The parameters derived by the VLBI observations, in addition to the broad-band properties, confirm that PMN J0948+0022 is similar to flat spectrum radio quasars. Global e-VLBI is a reliable and promising technique for future studies.

description: The purpose of this project was to identify facilitators and barriers to human papillomavirus (HPV) vaccine among community college students as a quality improvement study. The study used the Health Belief Model as the framework guiding this research. Data were collected using a paper and pencil survey given to students seeking services at a community college student health center. Thirty-seven subjects were included in the study. Data provided in the confidential surveys revealed that demographic data and health behaviors were not significant predictors of HPV vaccine status. The most influential predictor of vaccine status was information or a recommendation from the healthcare provider.

description: Bionic vision uses neuroprostheses to restore useful vision to people living with incurable blindness. However, a major outstanding challenge is predicting what people 'see' when they use their devices. The limited field of view of current devices necessitates head movements to scan the scene, which is difficult to simulate on a computer screen. In addition, many computational models of bionic vision lack biological realism. To address these challenges, we present VR-SPV, an open-source virtual reality toolbox for simulated prosthetic vision that uses a psychophysically validated computational model to allow sighted participants to 'see through the eyes' of a bionic eye user. To demonstrate its utility, we systematically evaluated how clinically reported visual distortions affect performance in a letter recognition and an immersive obstacle avoidance task. Our results highlight the importance of using an appropriate phosphene model when predicting visual outcomes for bionic vision.
