description: We present the calibration of the spectroscopic Lick/IDS standard line-index system for measurements obtained with the Gemini Multi-Object Spectrographs known as GMOS-North and GMOS- South. We provide linear correction functions for each of the 25 standard Lick line indices for the B600 grism and two instrumental setups, one with 0.5 arcsecond slit width and 1x1 CCD pixel binning (corresponding to ~2.5 Angstroem spectral resolution) and the other with 0.75 arcsecond slit width and 2x2 binning (~4 Angstroem). We find small and well-defined correction terms for the set of Balmer indices Hbeta, HgammaA, and HdeltaA along with the metallicity sensitive indices Fe5015, Fe5270, Fe5335, Fe5406, Mg2 and Mgb that are widely used for stellar population diagnostics of distant stellar systems. We find other indices that sample molecular absorption bands, such as TiO1 and TiO2, with very wide wavelength coverage or indices that sample very weak molecular and atomic absorption features, such as Mg1, as well as indices with particularly narrow passband definitions, such as Fe4384, Ca4455, Fe4531, Ca4227, and Fe5782, less robustly calibrated. These indices should be used with caution.

description: We have recently demonstrated that optical pumping methods combined with photoassociation of ultra-cold atoms can produce ultra-cold and dense samples of molecules in their absolute rovibronic ground state. More generally, both the external and internal degrees of freedom can be cooled by addressing selected rovibrational levels on demand. Here, we recall the basic concepts and main steps of our experiments, including the excitation schemes and detection techniques we use to achieve the rovibrational cooling of Cs2 molecules. In addition, we present the determination of formation pathways and a theoretical analysis explaining the experimental observations. These simulations improves the spectroscopic knowledge required to transfer molecules to any desired rovibrational level.

description: We introduce a new framework for loop quantum gravity: mimicking the spinfoam quantization procedure we propose to study the symmetric sectors of the theory imposing the reduction weakly on the full kinematical Hilbert space of the canonical theory. As a first application of Quantum-Reduced Loop Gravity we study the inhomogeneous Bianchi I model. The emerging quantum cosmological model represents a simplified arena on which the complete canonical quantization program can be tested. The achievements of this analysis could elucidate the relationship between Loop Quantum Cosmology and the full theory.

description: The idea of left-right symmetry with mirror fermions is very appealing from the symmetry point of view. In this picture, unlike the Standard Model, the symmetry is not only left-right symmetric, but each left handed fermion multiplet is accompanied by new right handed fermion multiplet of opposite chirality. In this work, we consider a gauge symmetry, $SU(3)_c \otimes SU(2)_L\otimes SU(2)_R \otimes U(1)_{Y^\prime}$ supplemented by a discrete $Z_2$ symmetry. Instead of having right handed multiplets for each left handed multiplets of the same fermions as in the usual left-right model, the mirror model include right handed doublets involving new fermions (called mirrors), and similarly for each right handed singlet, there are corresponding mirror singlets. Thus the gauge anomaly is naturally absent in this model, and the model also provide a solution for the strong CP problem because of parity conservation. The first stage of symmetry breaking is achieved by a doublet mirror Higgs with a vacuum expectation value $\simeq 10^7$ GeV, needed to explain the neutrino mass $\simeq 10^{-11}$ GeV. The mirror fermions can mix with the ordinary fermions via a scalar which is singlet under the gauge symmetry. In this model, only light mirror particles, having masses in the few hundred GeV range are $\hat{e}, \hat{u}, \hat{d}$ with well-defined spectrum. $\hat{u}$ and $\hat{d}$ can be pair produced at the LHC, and can be detected as ($u Z$) and ($d Z$) resonances. We discuss the signals of these mirror fermions at the LHC, and find that the reach at the LHC can be as large as $m_{\hat q}\simeq 800$ GeV.

The Planck Sunyaev-Zel'dovich vs. the X-ray View of the Coma Cluster

description: The Planck collaboration has recently published precise and resolved measurements of the Sunyaev-Zel'dovich effect in Abell 1656 (the Coma cluster of galaxies), so directly gauging the electron pressure profile in the intracluster plasma. On the other hand, such a quantity may be also derived from combining the density and temperature provided by X-ray observations of the thermal bremsstrahlung radiation emitted by the plasma. We find a model-independent tension between the SZ and the X-ray pressure, with the SZ one being definitely lower by 15-20%. We propose that such a challenging tension can be resolved in terms of an additional, non-thermal support to the gravitational equilibrium of the intracluster plasma. This can be straightforwardly included in our Supermodel, so as to fit in detail the Planck SZ profile while being consistent with the X-ray observables. Possible origins of the nonthermal component include cosmic-ray protons, ongoing turbulence, and relativistic electrons; given the existing observational constraints on the first two options, here we focus on the third. For this to be effective, we find that the electron population must include not only an energetic tail accelerated to gamma> 10^3 responsible for the Coma radiohalo, but also many more, lower energy electrons. The electron acceleration is to be started by merging events similar to those which provided the very high central entropy of the thermal intracluster plasma in Coma.

Instability of flat disks with respect to the formation of twisted ribbons in smectic-A monolayers

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Smectic-A monolayers self-assembled from aqueous solutions of chiral fd viruses and a polymer depletant can assume a variety of shapes such as flat disks and twisted ribbons. A theoretical model based on the de Gennes model for the smectic A phase, the Helfrich model of membrane elasticity and a simple edge energy has been previously used to calculate the disk-ribbon phase diagram. In this paper we apply this model to the nucleation process of ribbons. First, we study the "rippled disks" that have been observed as precursors of ribbons. Using a model shape proposed by Meyer which includes rippling in both the in-plane and out of plane directions, we study the energetics of the disks as functions of the edge energy modulus (a measure of the polymer concentration) and the mean curvature modulus k. We find that as the edge energy modulus is reduced the radial size of the ripples grows rapidly in agreement with experimental observations. For small enough k we find that the out of plane size of the ripples grows but its value saturates at a fraction of the twist penetration depth, too small to be experimentally observable. For large k the membrane remains flat though rippled in the radial direction. Such membranes do not have negative Gaussian curvature and thus will not likely spawn twisted ribbons. We also study the creation of twisted ribbons produced by stretching the edge of a flat membrane in a localized region. In experiments using a pair of optical traps it has been observed that once the membrane has been sufficiently stretched a ribbon forms on the stretched edge. We study this process theoretically using a free energy consisting of the Helfrich and edge energies alone. We add a small ribbon-like perturbation to the protrusion producd by stretching and determine whether it is energetically favorable as a function of the size of the protrusion.

description: The evolution of the magnetic order in FeSeTe crystals as a function of Se content was investigated by means of ac/dc magnetometry and muon-spin spectroscopy. Experimental results and self-consistent DFT calculations both indicate that muons are implanted in vacant iron-excess sites, where they probe a local field mainly of dipolar origin, resulting from an antiferromagnetic (AFM) bicollinear arrangement of iron spins. This long-range AFM phase disorders progressively with increasing Se content. At the same time all the tested samples manifest a marked glassy character that vanishes for high Se contents. The presence of local electronic/compositional inhomogeneities most likely favours the growth of clusters whose magnetic moment "freezes" at low temperature. This glassy magnetic phase justifies both the coherent muon precession seen at short times in the asymmetry data, as well as the glassy behaviour evidenced by both dc and ac magnetometry.

description: The dynamic suitability of two rainwater harvesting (RWH) structures was determined using a global hydrological model, PCR-GLOBWB 2. The two RWH structures were the “Vallerani”, consisting of furrows dug on a hillslope and the Marab, a larger structure designed to catch runoff. These two structures are reliant on several runoff events occurring each year. PCR-GLOBWB 2 was used with two precipitation forcings, W5E5 and CHIRPS, to simulate historical runoff for Central and West Asia. These results were then evaluated and average runoff depth, the number of runoff days and the variability of runoff were determined for the study area on a 5 arcmin grid scale. CHIRPS forcing showed less variable runoff generation but also less total runoff occurring when compared to W5E5 Comparison to observed runoff data, model results underestimated runoff, both in the average depth and the number of days. Results of the modelling exercise could therefore not be used to determine suitability, but rather the method used could be used as a framework. Discrepancy of observed and modelled runoff is likely due to poor model parameterization, with small scale rainfall-runoff generation not properly occurring. Furthermore, input data could be improved, and model resolution increased to yield better results in future.

description: We present fabrication and optical characterization of micro-cavities made of multilayer graphene (MLG) cantilevers clamped by metallic electrodes and suspended over Si/Si02 substrate. Graphene cantilevers act as a semi-transparent mirrors closing an air-wedge optical cavity. This simple geometry implements a standing-wave optical resonator along with a mechanical one. Equal thickness interference fringes are observed in both Raman and Rayleigh backscattered signals with interfringe given by their specific wavelength.Chromatic dispersion within the cavity makes possible spatial modulation of graphene Raman lines and selective rejection of the silicon background signals. Electrostatic actuation of the multilayer graphene cantilever by gate voltage tunes the cavity length and induces space and time modulation of backscattered light including Raman lines. We demonstrate the potential of those systems for high sensitivity Raman measurements of generic molecular species grafted on multilayer graphene surface. The Raman signal of the molecular layer can be modulated both in time and in space in a similar fashion and show enhancement with respect to a collapsed membrane.

Constraints on the origin of cosmic rays above $10^{18}$ eV from large scale anisotropy searches in data of the Pierre Auger Observatory

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: A thorough search for large scale anisotropies in the distribution of arrival directions of cosmic rays detected above $10^{18}$ eV at the Pierre Auger Observatory is reported. For the first time, these large scale anisotropy searches are performed as a function of both the right ascension and the declination and expressed in terms of dipole and quadrupole moments. Within the systematic uncertainties, no significant deviation from isotropy is revealed. Upper limits on dipole and quadrupole amplitudes are derived under the hypothesis that any cosmic ray anisotropy is dominated by such moments in this energy range. These upper limits provide constraints on the production of cosmic rays above $10^{18}$ eV, since they allow us to challenge an origin from stationary galactic sources densely distributed in the galactic disk and emitting predominantly light particles in all directions.

description: In De Impressionibus Elementorum, a treatise written by Grosseteste shortly after 1220, we can find a discussion of some phenomena involving the four classical elements (air, water, fire and earth), in the framework of an Aristotelian physics of the atmosphere. However this treatise strongly differentiates from similar works of the twelfth century for its referring to experiments. In fact, it contains some descriptions of phase transitions which are rather interesting, in particular when Grosseteste is discussing of bubbles.

title: A Geochemical Analysis of Tosawihi Quarries Chert Using X-Ray Fluorescence Spectrometry
Creators: name: Wurster, Bethany M.
Publisher: name: Utah State University
Year: 2019

description: Lithic source analysis, or “sourcing,” is a geochemical compositional analysis of lithic materials for both major and trace elements. Sourcing analysis assigns lithic sources to geochemical groups according to distinct geochemical compositions, where unique elemental signatures represent separate lithic sources. In archaeological research, sourcing informs upon mobility strategies, trade and exchange networks, and lithic conveyance studies. While obsidian sourcing is a relatively reliable and popular technique, chert sourcing is more difficult and historically less successful largely due to variability in chert formation processes. X-ray fluorescence spectrometry (XRF) offers a possible sourcing technique, and is non-destructive, as well as time and cost-effective. In this thesis, I test the reliability of XRF in determining the geochemical characterization of Tosawihi Quarries chert, a unique chert source located in the Humboldt River Basin of north-central Nevada.

The Tosawihi Quarries archaeological district (26EK6624) is a significant lithic resource that has hosted human occupation and activity for millennia. The Tosawihi Quarries offers a high quality toolstone that was intensely used, as indicated by numerous quarry locales and biface tool caches. Additionally, the Tosawihi Quarries is a social identity marker for the Tosawihi band of Western Shoshone, also serving as a source of spirituality and medicine. Tosawihi chert is a distinct, white lithic material type that also has a characteristic fluorescence pattern when exposed to ultraviolet light. While these are defining attributes, they are not unique to Tosawihi chert, as they occur in other Great Basin white chert sources. Identifying Tosawihi chert has been problematic, and misidentifications may have led to erroneous interpretations of the archaeological and ethnographic records. If successful, a geochemical characterization by XRF would provide an elemental signature specific to Tosawihi chert, thus eliminating discrepancies in visual and ultraviolet fluorescence readings and permitting archaeologists to accurately asses the distribution and use of this sacred material.

In this thesis research, I first conducted an XRF analysis of a source standard collection of Tosawihi Quarries chert, which yielded a preliminary methodology for identifying Tosawihi chert. This protocol was tested against two comparative collections of other Great Basin white cherts: Mono Lake Spillway located in western Nevada and Pahute Mesa (26NY1408) located in southern Nevada. The methodology, now refined, was then run against the archaeological collection, where five collections of white chert artifacts were tested for the presence of Tosawihi chert. Incorporating both the qualitative and quantitative data from XRF analysis, the results show that this proposed methodology can successfully discriminate between Tosawihi chert and other Great Basin white cherts based on its XRF signature.
title: Twenty-First Century Skills: A Needs Assessment of School-Based Agricultural Education Teachers

description: Preparing students to be career and work ready is a concern of educators and schools nationwide. Twenty-first century skills prepare students to enter the workforce or higher education with the ability to think critically and creatively, collaborate with others, take the initiative when approached with a task, and use technology to its fullest potential. If students are not learning the skills needed for success, it is because educators and schools are not teaching them. When students possess these skills, they are prepared to work in teams, think critically and creatively about a problem, display leadership and social skills, and communicate effectively with others.

The research sought to identify school-based agriculture education teachers perceived knowledge, importance, and ability to teach these 21st -century skills in the classroom. Results showed that agriculture teachers nationwide find 21st -century skills to be important, but they are less knowledgeable and able to teach them. The research concluded that professional development is needed to increase teacher’s knowledge of and ability to teach 21st -century skills. Professional development will allow school-based agricultural education teachers to gain specific and applicable strategies for implementation. With the application of 21st -century skills in the school-based agricultural education classroom, students will become better prepared to enter the workforce or higher education upon graduating high school.
title: Health Care Provider Recruitment and Retention in Millard County, Utah

description: Millard County, Utah, rural and sparsely populated, continues to experience challenges in recruiting and retaining primary health care providers. My study addressed the lack of a rigorous and systemic analysis of this problem by collecting and analyzing data from a series of semi-structured interviews conducted between January and March 2019. These interviews were with nineteen of the twenty-four known health care providers who began practice in the county from the mid 1980s to 2018, as well as with four administrators.

The study, taking advantage of this comprehensive analysis, provided a more extensive understanding of the root causes underlying the recruitment and retention shortcomings. Findings showed that decisions to stop practice in the county were not typically made for a single over-riding reason but occurred when the cumulative effect of negative experiences reached a tipping point, prompting the provider to seek another practice venue. Providers who left reached this tipping point in spite of most having a rural background.

The study recommended implementing a comprehensive and on-going support program aimed at addressing providers concerns. The stressors associated with rural health care practices need to be regularly assessed and resolved in a timely fashion.

description: We report on the transport properties of clean, epitaxial Fe(Se,Te) thin films prepared on Fe-buffered MgO (001) single crystalline substrates by pulsed laser deposition. Near Tc a steep slope of the upper critical field for H||ab was observed (74.1 T/K), leading to a very short out-of-plane coherence length, ξc, of 0.2 nm, yielding 2ξc(0) approximately 0.4 nm. This value is shorter than the interlayer distance (0.605 nm) between Fe-Se(Te) planes, indicative of modulation of the superconducting order parameter along the c-axis. An inverse correlation between the power law exponent N of the electric field-current density (E-J) curve and the critical current density, Jc, has been observed at 4 K, when the orientation of H was close to the ab-plane. These results prove the presence of intrinsic pinning in Fe(Se,Te). A successful scaling of the angular dependent Jc and the corresponding exponent N can be realized by the anisotropic Ginzburg Landau approach with appropriate Γvalues 2~3.5. The temperature dependence of Γbehaves almost identically to that of the penetration depth anisotropy.

description: We applied the simulated tempering and magnetizing (STM) method to the two-dimensional three-state Potts model in an external magnetic field in order to perform further investigations of the STM's applicability. The temperature as well as the external field are treated as dynamical variables updated during the STM simulations. After we obtained adequate information for several lattice sizes $L$ (up to $160\times 160$), we also performed a number of conventional canonical simulations of large lattices, especially in order to illustrate the crossover behavior of the Potts model in external field with increasing $L$. The temperature and external field for larger lattice size simulations were chosen by extrapolation of the detail information obtained by STM. We carefully analyzed the crossover scaling at the phase transitions with respect to the lattice size as well as the temperature and external field. The crossover behavior is clearly observed in the simulations in agreement with theoretical predictions.

description: Diese Arbeit beschäftigt sich mit fehlertoleranten Radnabenantrieben mit integrierter Leistungselektronik für Elektrofahrzeuge. Die Besonderheit des betrachteten Fahrzeugtyps ist, dass die Bremsfunktion an den angetriebenen Rädern vollständig von den Radnabenantrieben übernommen wird, sodass an diesen Rädern keine zusätzlichen Reibungsbremsen notwendig sind. Im Rahmen der Arbeit wird für diese Anwendung zunächst eine optimale Topologie für den elektrischen Antriebsstrang ermittelt. Auf dieser Topologie aufbauend wird im nächsten Schritt ein Sicherheitskonzept für den Leistungsteil des elektrischen Antriebsstrangs entwickelt. Zur Umsetzung dieses Sicherheitskonzepts werden anschließend zwei neu entwickelte Verfahren zur halbleiternahen Erkennung von Halbbrückenkurzschlüssen vorgestellt und untersucht. Darüber hinaus wird eine Methodik zur Berechnung der Zwischenkreisbelastung entwickelt. Diese ermöglicht eine vereinfachte Berechnung der im Betrieb auftretenden Belastungen unter Berücksichtigung der Wechselwirkungen zwischen den verteilten leistungselektronischen Komponenten.

description: We propose and demonstrate a momentum filter for atomic gas based on a designed Talbot-Lau interferometer. It consists in two identical optical standing wave pulses separated by a delay equal to odd multiples of the half Talbot time. The one dimensional momentum width along the long direction of a cigar shape condensate is rapidly and greatly purified to a minimum, which corresponds to the ground state energy of the confining trap in our experiment. We find good agreement between theoretical analysis and experimental results. The filter is also effective for non-condensed cold atoms and could be applied widely.
