description: We present stereoscopic reconstructions of the location and inclination of polar plumes of two data sets based on the two simultaneously recorded images taken by the EUVI telescopes in the SECCHI instrument package onboard the \emph{STEREO (Solar TErrestrial RElations Observatory)} spacecraft. The ten plumes investigated show a superradial expansion in the coronal hole in 3D which is consistent with the 2D results. Their deviations from the local meridian planes are rather small with an average of $6.47^{\circ}$. By comparing the reconstructed plumes with a dipole field with its axis along the solar rotation axis, it is found that plumes are inclined more horizontally than the dipole field. The lower the latitude is, the larger is the deviation from the dipole field. The relationship between plumes and bright points has been investigated and they are not always associated. For the first data set, based on the 3D height of plumes and the electron density derived from SUMER/\emph{SOHO} Si {\sc viii} line pair, we found that electron densities along the plumes decrease with height above the solar surface. The temperature obtained from the density scale height is 1.6 to 1.8 times larger than the temperature obtained from Mg {\sc ix} line ratios. We attribute this discrepancy to a deviation of the electron and the ion temperatures. Finally, we have found that the outflow speeds studied in the O {\sc vi} line in the plumes corrected by the angle between the line of sight and the plume orientation are quite small with a maximum of 10 $\mathrm{km s^{-1}}$. It is unlikely that plumes are a dominant contributor to the fast solar wind.

description: We present uSR investigations on SmFeAsO_1-xF_x showing coexistence of magnetic order and superconductivity only in a very narrow F-doping range. The sharp crossover between the two types of order is similar to that observed in LaFeAsO_1-xF_x, suggesting a common behavior for the 1111 pnictides. The analysis of the muon asymmetry demonstrates that the coexistence must be nanoscopic, i.e. the two phases must be finely interspersed over a typical length-scale of few nm. In this regime both the magnetic and the superconducting transition temperatures collapse to very low values. Our data suggest a competition between the two order parameters

Year: 1992
Subjects: Ethnology--Mexico
Indigenous peoples--Mexico
Mexico--Population

description: The study of the great diversity of culture encountered throughout Mexico was first undertaken by a handful of Catholic friars directly following the arrival of the Spanish. However, except for some observations recorded in the written accounts of occasional travelers through the area, little concern was shown towards the native populations until late in the nineteenth century. Since the conclusion of the Revolution of 1910, there has been a growing interest in understanding their way of life and documenting the changes brought about by the increasing contact with modern civilization. This bibliography presents a selection of anthropological studies about the indigenous cultures of Mexico which were produced from 1920 to 1991.

description: This bibliography focuses on the history of plant science in South America through the early nineteenth century. The Benson Collection's holdings in this area are significant and include rare books, fascimile editions, and large, elaborately produced reports of botanical expeditions. Much of the material listed is kept in the Rare Books and Manuscripts division of the library. The history of plant science in Latin America can be divided into three large areas: 1) The indigenous traditions, some of which are partially preserved in pre-Conquest picture writing and other artifacts, as well as in early post-Conquest histories and ethnographies; 2) 16th and 17th century attempts by Europeans to discover materia medica--medically useful plants or drugs--in the Western hemisphere; and 3) the age of the Enlightenment and of modern botanical science and expeditions. All materials listed are in the Benson Latin American Collection.

description: Using the pseudopotential density functional method, we find that a Be atom on a nanostructure with H2 molecules forms a Be-dihydrogen complex through the hybridization of the Be s or p orbits with the H2 sigma orbits and the binding energy of the H2 molecules is in the range of ~0.3 - 0.8 eV/H2. We also study Be-dihydrogen complexes on various nanostructures and demonstrate the feasibility of the application of the complexes to a hydrogen storage medium that operates near room temperature and ambient pressure.

description: Charge Coupled Devices (CCDs) have been successfully used in several high energy physics experiments over the past two decades. Their high spatial resolution and thin sensitive layers make them an excellent tool for studying short-lived particles. The Linear Collider Flavour Identification (LCFI) collaboration is developing Column-Parallel CCDs (CPCCDs) for the vertex detector of a future Linear Collider. The CPCCDs can be read out many times faster than standard CCDs, significantly increasing their operating speed. An Analytic Model has been developed for the determination of the charge transfer inefficiency (CTI) of a CPCCD. The CTI values determined with the Analytic Model agree largely with those from a full TCAD simulation. The Analytic Model allows efficient study of the variation of the CTI on parameters like readout frequency, operating temperature and occupancy.

description: We present the first observation of the Zgamma to nunugamma process at the Tevatron at 5.1 standard deviations significance, based on 3.6 fb-1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron ppbar Collider at sqrt{s} = 1.96 TeV. The measured Zgamma cross section multiplied by the branching fraction of Z to nunu is 32 +- 9 (stat.+syst.) +- 2 (lumi.) fb for the photon ET > 90 GeV. It is in agreement with the standard model prediction of 39 +- 4 fb. We set the most restrictive limits on anomalous trilinear Zgammagamma and ZZgamma gauge boson couplings at a hadron collider to date, with three constraints being the world's strongest.

A category of topological spaces and sheaves
Creators: name: Fraga, Robert Joseph
Publisher: name: University of British Columbia
Year: 2011

description: The problem of this paper is to define a category of topological spaces and sheaves in topological and algebraic terms. It is then necessary to show that if the topological space is, in particular, affine space and the sheaf over it the sheaf of germs of regular functions* then the pair, consisting of the topological space and the sheaf of germs of regular functions, called an affine variety, is an element of the category. We then generalize this result by showing that algebraic varieties belong to the category. Before defining the category, it is necessary to establish in Section 1 some elementary results of general topology which are used in proving properties of the category. It is also necessary to define the Zariski topology in purely topological terms. This is done in Section 2.

description: We analyze generalized Gaussian cat states obtained by superposing arbitrary Gaussian states, e.g., a coherent state and a squeezed state. The Wigner functions of such states exhibit the typical pair of Gaussian hills plus an interference term which presents a novel structure, as compared with the standard superposition of coherent states (degenerate case). We prove that, in any dimensions, the structure of the interference term is characterized by a particular quadratic form; in one degree of freedom the phase is hyperbolic. This phase-space structure survives the action of a thermal reservoir. We also discuss certain superpositions of {\em mixed} Gaussian states generated by conditional Gaussian operations or Kerr-type dynamics on thermal states.

title: BENCH: Biorhythmic Evaporative-cooling Nano-TeCH
Creators: name: Ida, Aletheia
Publisher: name: University of Mass Amherst
Year: 2019

description: The Biorhythmic Evaporative-cooling Nano-TeCH (BENCH) system is conceived as a novel building skin for architectural enclosures responsive to human interactions for thermal comfort in hot-arid climate conditions. The membrane system concurrently integrates natural ventilation cooling and modulations in daylighting transmission for inhabitant wellbeing and multi-sensory phenomena experience. The BENCH demonstration prototype combines CNC shaped and stained laminated plywood with all wood joinery for the structure of a small covered seating area with atmospheric effects. The soft skin membrane encloses the structure with embedded hydrogels that are actuated with water pumping into the mesh pod modules through clear microbore tubing. Each gel pod module expands during swelling, which induces the lift of an outer flap to allow for airflow through the skin. When air flows through the flaps, it carries humidity off of the gel pods and into the surrounding atmosphere for human thermal comfort cooling effects. There are three small water pumps located under each bench module on the floor. Humidity and temperature sensors are incorporated into the BENCH prototype and link to an automated hydro-pump actuator through Arduino servo motor control. The GEMS prototype is pre-tested with sensing and actuating functionality in an environmental test-chamber in a controlled lab setting. The demonstration prototype is currently being fabricated and will be installed for in-situ real-time testing beginning in May 2019. The project integrates the research and development of the author’s work through collaborations with material science, electrical and computer engineering, and human health and wellbeing. Future work with the prototypes includes human wellbeing research in a living-lab setting with non-invasive biometric sensing for heart rate variability and sweat biomarkers in correlation to BENCH environmental fluctuations for temperature, humidity, and dynamic daylight conditions.

An experimental investigation of equilibrium conditions in a shock plasma
Creators: name: Neufeld, Carl Richard
Publisher: name: University of British Columbia
Year: 2011

description: Photoelectric measurements were made of the shock-excited spectrum of a mixture of helium and argon. The electron density behind the shock wave and the temperatures of the plasma components were deduced from the spectroscopic measurements, assuming thermal equilibrium conditions in the shock plasma. The two temperatures were in fairly good agreement, supporting the equilibrium assumption. On the other hand, the temperature and electron density differ significantly from values expected for a one-dimensional shock wave.

description: To support the State of Hawaii’s goals of improving energy performance of buildings and reducing dependence on fossil fuels, this study develops design recommendations that could improve the energy efficiency and thermal comfort of hundreds of existing and future homes for native Hawaiian families.

This poster shares the methods and learning objectives used by faculty, researchers, and a team of architecture, electrical and mechanical engineering, and computer science students to chart a path to net-zero site energy use in residences in sub-tropical climates by monitoring and simulating existing houses.

The faculty from Architecture and Sea Grant structured the research project into multiple phases over two years: 1) Monitor Existing Buildings; 2) Calibrate Simulated Whole Building Energy Models; 3) Simulate Potential Design for Future Energy Code; 4) Simulate Potential Energy Efficiency Improvements; 5) Estimate Potential Renewable Energy Production and; 6) Communicate Recommendations to Developers and Residents.

In this study, three existing house typologies are studied: naturally ventilated (no air conditioning); partially air-conditioned; and centrally air-conditioned. Student and senior researcher teams monitor and manage data for temperature, humidity, and sub-metered for electricity in nine houses for one year. Air conditioning comprises a larger portion of the monitored houses’ total energy use as compared to national hot-humid climate residential averages. The monitored data shows most occupants chose to use air conditioning year round despite the mild climate and high electricity rates. In addition, monitored data shows plug loads vary between houses by more than a factor of two.

Student researchers using computational building performance simulation in NREL’s BEopt with Energy Plus find that the most effective energy efficiency measures are 1) improving the air conditioning SEER rating and 2) increasing the thermostat cooling setpoint while using ceiling fans with occupancy sensors. The team graphically communicates recommendations and presents them to developers and homeowners for potential incorporation into the next hundreds of homes planned for construction.

description: We present a novel scenario for globular cluster (GC) formation, where the ultraviolet (UV) background radiation effectively works so as to produce compact star clusters. Here, we explore the formation of GCs in UV radiation fields. For this purpose, we calculate baryon and dark matter (DM) dynamics in spherical symmetry, incorporating the self-shielding effects by solving the radiative transfer of UV radiation. In addition, we prescribe the star formation in cooled gas components and pursue the dynamics of formed stars. As a result, we find that the evolution of subgalactic objects in UV background radiation are separated into three types, that is, (1) prompt star formation, where less massive clouds ~10^{5-8} M_sun are promptly self-shielded and undergo star formation, (2) delayed star formation, where photoionized massive clouds >10^8 M_sun collapse despite high thermal pressure and are eventually self-shielded to form stars in a delayed fashion, and (3) supersonic infall, where photoionized less massive clouds ~10^{5-8} M_sun contract with supersonic infall velocity and are self-shielded when a compact core forms. In particular, the type (3) is a novel type found in the present simulations, and eventually produces a very compact star cluster. The resultant mass-to-light ratios, half-mass radii, and velocity dispersions for the three types are compared to the observations of GCs, dwarf spheroidals (dSphs), and ultra-compact dwarfs (UCDs). It turns out that the properties of star clusters resulting from supersonic infall match well with those of observed GCs, whereas the other two types are distinct from GCs. Hence, we conclude that supersonic infall in a UV background is a promising mechanism to form GCs.

description: The lifetime of isolated protoplanetary disks is thought to be set by the combination of viscous accretion and photoevaporation driven by stellar high-energy photons. Observational evidence for magnetospheric accretion in young sun-like stars is robust. Here we report the first observational evidence for disk photoevaporation driven by the central star. We acquired high-resolution (R~30,000) spectra of the [NeII] 12.81 micron line from 7 circumstellar disks using VISIR on Melipal/VLT. We show that the 3 transition disks in the sample all have [NeII] line profiles consistent with those predicted by a photoevaporative flow driven by stellar extreme UV photons. The ~6 km/s blue-shift of the line from the almost face-on disk of TW Hya is clearly inconsistent with emission from a static disk atmosphere and convincingly points to the presence of a photoevaporative wind. We do not detect any [NeII] line close to the stellar velocity from the sample of classical optically thick (non-transition) disks. We conclude that most of the spectrally unresolved [NeII] emission in these less evolved systems arises from jets/outflows rather than from the disk. The pattern of the [NeII] detections and non-detections suggests that extreme UV-driven photoevaporation starts only at a later stage in the disk evolution.

Creators: name: Huang, Lisa

Publisher: name: University of Massachusetts Amherst
Year: 2019

description: The purpose of the study is to develop a studio course that is a precursor to the integrative studio in the University of Florida Master of Architecture curriculum. The studio course introduces each building technology discipline as design concept generators and the course intends to prepare students not to think of building technologies in only practical terms but to integrate a conceptual thinking regarding building technologies in their design work. Our primary goal is for the students to discover poetic approaches for working with building technologies before they need to integrate all disciplines simultaneously in their design work. The studio tests three projects in a 16-week semester: one project generated from materials and construction methods, a second rooted in structural principles at multiple scales, and the third centered on environmental strategies for extreme climates. In the first project, the students were challenged with the connecting their speculative proposals with built reality. In the third project, they had to address places and conditions that are beyond their own experience. In all three projects, we found that the majority of students struggled with the application of building technology principles in their design process. There was a disconnect between practicalities and conceptual thinking. In our analysis, this indicates that building technologies may not be most effective when they are separate studies isolated from studio design.

description: This paper presents a study of the atmospheric refraction and its effect on the light coupling efficiency in an instrument using single-mode optical fibers. We show the analytical approach which allowed us to assess the need to correct the refraction in J- and H-bands while observing with an 8-m Unit Telescope. We then developed numerical simulations to go further in calculations. The hypotheses on the instrumental characteristics are those of AMBER (Astronomical Multi BEam combineR), the near infrared focal beam combiner of the Very Large Telescope Interferometric mode (VLTI), but most of the conclusions can be generalized to other single-mode instruments. We used the software package caos (Code for Adaptive Optics Systems) to take into account the atmospheric turbulence effect after correction by the ESO system MACAO (Multi-Application Curvature Adaptive Optics). The opto-mechanical study and design of the system correcting the atmospheric refraction on AMBER is then detailed. We showed that the atmospheric refraction becomes predominant over the atmospheric turbulence for some zenith angles z and spectral conditions: for z larger than 30{\circ} in J-band for example. The study of the optical system showed that it allows to achieve the required instrumental performance in terms of throughput in J- and H-bands. First observations in J-band of a bright star, alpha Cir star, at more than 30{\circ} from zenith clearly showed the gain to control the atmospheric refraction in a single mode instrument, and validated the operating law.

description: We show several properties related to the structure of the family of classes of two-dimensional periodic continued fractions. This approach to the study of the family of classes of nonequivalent two dimexsional periodic continued fractions leads to the visualization of special subfamilies of continued fractions with torus triangulations (i.e. combinatorics of their fundamental domains) that possess explicit regularities.Several cases of such subfamilies are studied in detail; the method to construct other similar subfamilies is given.

description: We present a Rayleigh-Ritz method for the approximation of fluid flow in a curved duct, including the secondary cross-flow, which is well known to develop for nonzero Dean numbers. Having a straightforward method to estimate the cross-flow for ducts with a variety of cross-sectional shapes is important for many applications. One particular example is in microfluidics where curved ducts with low aspect ratio are common, and there is an increasing interest in nonrectangular duct shapes for the purpose of size-based cell separation. We describe functionals which are minimized by the axial flow velocity and cross-flow stream function which solve an expansion of the Navier-Stokes model of the flow. A Rayleigh-Ritz method is then obtained by computing the coefficients of an appropriate polynomial basis, taking into account the duct shape, such that the corresponding functionals are stationary. Whilst the method itself is quite general, we describe an implementation for a particular family of duct shapes in which the top and bottom walls are described by a polynomial with respect to the lateral coordinate. Solutions for a rectangular duct and two nonstandard duct shapes are examined in detail. A comparison with solutions obtained using a finite-element method demonstrates the rate of convergence with respect to the size of the basis. An implementation for circular cross-sections is also described, and results are found to be consistent with previous studies.

description: Dense and cold electron beams can be of extreme interest for ion beam cooling [1] and for the generation of coherent electromagnetic radiation in the microwave range through tre Free Electron Laser process [2]. The high current needed in these applications requires a very efficent energy recovery in the electron accelerator, to save installed power, so that nondestructive diagnostics have to be taken into account for full intensity tests. A project of a high-energy electron cooling device is actually in progress as an INFN collaboration. Several prototypes have been successfully tested and the final version has been constructed in the Frascati Laboratories. The first tests will be performed in the Legnaro Laboratories [3]. The apparatus consists of a high-frequency (40 kHz) Cockcroft-Walton generator (760 kV nominal voltage) with very low ripple (10^-4) and high stability, a Pierce electron gun followed by an accelerating tube and an energy recovery system. The energy recovery system consists of a decelerating column, similar to the accelerating one, and a collector. In order to compensate the space charge effects for all the operating energies, the electron beam is guided by an axial magnetic field. A detailed description of the whole apparatus has been already published [3], while in Table I the main characteristics of the device are summarized. The transverse beam temperature will be measured by means of a pair of synchronous wave pick-up matched to the electron cyclotron frequency [4], and positioned at the two ends of the straight section. The same instrument can also give the beam position, allowing the reconstruction of the electron line of flight. The longitudinal energy spread and the transverse beam density can be measured from the spectral width and relative intensity of a laser light backward scattered from the electron beam [5].

description: In the framework of chiral perturbation theory we compute the ∆I = 3/2 contribution to K_L K→π^0 γγ. As for the ∆I = 1/2 transition, the result turns out to be unambiguously predicted and finite. We discuss also the effects on this decay coming from O(p^4) corrections to K→3π. As a by-product we have also a prediction for the CP conserving amplitude A(K_L → π^0 e^+ e^-).

description: A LiFeAs single crystal with $T_c^{onset}$$\sim$19.7 K was grown successfully in a sealed tungsten crucible using the Bridgeman method. The electrical resistivity experiments revealed a ratio of room temperature to residual resistivity (RRR) of approximately 46 and 18 for the in-plane and out-of plane directions. The estimated anisotropic resistivity, $γ_ρ$=$ρ_c$ / $ρ_{ab}$, was approximately 3.3 at $T_c^{onset}$. The upper critical fields had large $H_{c2} ^{\shortparallel ab}$ and $H_{c2}^{\shortparallel c}$ values of 83.4 T and 72.5 T, respectively, and an anisotropy ratio is $γ_H$=$H_{c2}^{\shortparallel ab}$ / $H_{c2} ^{\shortparallel c}$$\sim$1.15. The high upper critical field value and small anisotropy highlight the potential use of LiFeAs in a variety of applications. The calculated critical current density $(J_c)$ from the $M$-$H$ loop is approximately 10$^3$ A/cm$^2$

description: We propose the construction of a detector dedicated to Nuclear Physics studies, called FINUDA, at DAFNE, the Frascati ∅-Factory. The initial physics program is focused on the spectroscopy and decay modes of Λ-hypernuclei, which are produced following of tagged K^{-} in nuclear targets. The unique property of kaons at DAFNE, coupled to the expected performances of FINUDA (momentum resolution of 0.2% FWHM, and dedicated triggers) will allow an unprecedented step forward concerning the precision of the measurements and, even more, the counting rates. At  l = 10^32 cm^-2 s^-1 we expect to produce and carefully study about 20 hypernuclei, most of them new. The puzzling situation regarding the validity of the ΛI=1/2 rule for non-mesonic decays of hypernuclei will be hopefully clarified. FINUDA could also be used for measurements on low K=N interaction.

description: Y1Ba2Cu3(YBCO) sintered pellets have been loaded at room temperature with hydrogen by means of electrolysis in an acqueous solution (LiOH 0,3 N) with μs current pulses. The superconducting features of loaded samples have been measured as a function of the temperature by the ac magnetic susceptibility. In some conditions the YBCO pellets exhibited an enhancement of the transition temperature up to 95,4 K without a significant weakening of the superconducting grain coupling. These effects appear strongly dependent on the loading conditions.
title: Synchronic and Diachronic Labor: Deconstructing Eladio Dieste's Ruled Surfaces
Creators: name: Lammers, Federico Garcia
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Eladio Dieste was a Uruguayan engineer whose practice prioritized the choreography of on-site labor during the second half of the twentieth century. Dieste’s structural innovations in reinforced masonry are admired for their geometric audacity, material economy, and experiential effects. This paper discusses the work and pedagogy from an ongoing architecture class called Dieste Building Shop. The course is a combination of history/theory seminar and building technology class, which focuses on the deconstruction and construction of one of Dieste’s innovations, ruled surface brick walls – double curvature surfaces defined by a series of vertical lines. One of the most underexamined aspects of Dieste’s oeuvre is its link to physical labor. This scholarly blind spot is the foundation of the labor-based pedagogy defined in Synchronic and Diachronic Labor. This type of pedagogy can establish diverse, socio- cultural networks that are intrinsic to technical knowledge. The intellectual distance between architecture and physical labor is a fundamental part of these overlooked technical histories. The effects of this historical schism are explained through the distinction between synchronic and diachronic conceptions of time and its impact on labor.
The application of direct-current resistivity prospecting methods to ice masses
Creators: name: Greenhouse, John Phillips
Publisher: name: University of British Columbia
Year: 2011

description: Direct-current resistivity prospecting methods have been used but rarely in the past in physical investigations of icecaps and glaciers. However these methods have the advantage of using light-weight and inexpensive equipment that is simple to operate. As part of the geophysical program of the Arctic Institute of North America's Devon Island Expedition, resistivity measurements were made in the accumulation and ablation zones of an ice-cap and on an adjoining glacier during the summers of 1961 and 1962. Depths of ice ranging from 50 to 750 meters were measured on the Sverdrup Glacier. Depth soundings on the ice-cap were not very successful owing primarily to insufficient power. However, some indication of the depth and composition of the firn was obtained. Ice resistivities were for the most part in the range from 4.10⁴ to 10⁵ ohm-meters, as compared with values of several megohm-meters found for temperate glaciers in lower latitudes. Variations of ice resistivities as a function of other physical properties were investigated.

description: We calculate the QED and QCD radiative corrections to the charged lepton energy distributions in the dominant semileptonic decays of the top quark $t \to b W^+ \to b(\ell^+ ν_\ell)$ $(\ell=e, μ, τ)$ in the standard model(SM), and for the decay $t \to b H^+ \to b(τ^+ ν_τ)$ in an extension of the SM having a charged Higgs boson $H^\pm$ with $m_{H^\pm} < m_t -m_b$. The QCD corrections are calculated in the leading and next-to-leading logarithmic approximations, but the QED corrections are considered in the leading logarithmic approximation only. These corrections are numerically important for precisely testing the universality of the charged current weak interactions in $t$-quark decays. As the $τ^+$ leptons arising from the decays $W^+ \to τ^+ ν_τ$ and $H^+\to τ^+ ν_τ$ are predominantly left- and right-polarised, respectively, influencing the energy distributions of the decay products in the subsequent decays of the $τ^+$, we work out the effect of the radiative corrections on such distributions in the dominant (one-charged prong) decay channels $ τ^+ \to π^+ \barν_τ, ρ^+ \barν_τ, a_1^+ \barν_τ$ and $\ell^+ ν_\ell \barν_τ$. The inclusive $π^+$ energy spectra in the decay chains $t \to b(W^+,H^+) \to b (τ^+ ν_τ) \to b (π^+ \barν_τν_τ+X)$ are calculated, which can help in searching for the induced $H^\pm$ effects at the Tevatron and the LHC.
