description: Several astrophysically relevant solid oxides and silicates have extremely small opacities in the visual and near-infrared in their pure forms. Datasets for the opacities and for the imaginary part k of their complex indices of refraction are hardly available in these wavelength ranges. We aimed at determining k for spinel, rutile, anatase, and olivine, especially in the near-infrared region. Our measurements were made with impurity-containing, natural, and synthetic stardust analogs. Two experimental methods were used: preparing small sections of natural minerals and synthesizing melt droplets under the electric arc furnace. In both cases, the aborption properties of the samples were measured by transmission spectroscopy. For spinel (MgAl2O4), anatase, rutile (both TiO2), and olivine ((Mg,Fe)2SiO4), the optical constants have been extended to the visual and near-infrared. We highlight that the individual values of k and the absorption cross section depend strongly on the content in transition metals like iron. Based on our measurements, we infer that k values below 10^(-5) are very rare in natural minerals including stardust grains, if they occur at all. Data for k and the absorption cross section are important for various physical properties of stardust grains such as temperature and radiation pressure. With increasing absorption cross section due to impurities, the equilibrium temperature of small grains in circumstellar shells increases as well. We discuss why and to what extent this is the case.

description: The increasing demand for high-quality cassava necessitates breeding programs to focus on improving the sensory, textural, and color attributes of eba. To guide these breeding efforts, understanding the acceptability thresholds for key quality parameters is crucial. By establishing clear sensory thresholds based on consumer preferences and descriptive sensory analysis, researchers can define the acceptable range for each quality trait. Additionally, translating these sensory thresholds into objective instrumental measurements will enable more efficient and cost-effective screening of candidate clones. By incorporating these components into breeding programs, researchers can accelerate the development of cassava varieties that consistently meet consumer expectations.

Nineteen (19) diverse cassava genotypes were harvested during the 2020-2023 planting season at the field plots of International Institute of Tropical Agriculture (IITA), Ikenne station. The genotypes were established in a randomized complete block design with two replications and harvested 12 months after planting. The harvested cassava was processed into gari and eba for further sensory evaluation and consumer preference tests. To assess consumer preferences, a "Just-About-Right" (JAR) scale with three points was used to evaluate colour, firmness, and stickiness. A total of 120 consumers were surveyed at the IITA staff canteen in October 2022. A quantitative descriptive analysis (QDA) was conducted by a trained panel of fifteen (15) individuals. Findings show that the threshold of acceptability for the color of gari ranges from 2.4 to 3.2, and optimum acceptability was 2.9 and R2 of 0.53, while the acceptability threshold for the Eba hardness ranges from 200 to 400 N, with optimum acceptability at 300 N.

description: Theories of planet formation predict the birth of giant planets in the inner, dense, and gas-rich regions of the circumstellar disks around young stars. These are the regions from which strong CO emission is expected. Observations have so far been unable to confirm the presence of planets caught in formation. We have developed a novel method to detect a giant planet still embedded in a circumstellar disk by the distortions of the CO molecular line profiles emerging from the protoplanetary disk's surface. The method is based on the fact that a giant planet significantly perturbs the gas velocity flow in addition to distorting the disk surface density. We have calculated the emerging molecular line profiles by combining hydrodynamical models with semianalytic radiative transfer calculations. Our results have shown that a giant Jupiter-like planet can be detected using contemporary or future high-resolution near-IR spectrographs such as VLT/CRIRES or ELT/METIS. We have also studied the effects of binarity on disk perturbations. The most interesting results have been found for eccentric circumprimary disks in mid-separation binaries, for which the disk eccentricity - detectable from the asymmetric line profiles - arises from the gravitational effects of the companion star. Our detailed simulations shed new light on how to constrain the disk kinematical state as well as its eccentricity profile. Recent findings by independent groups have shown that core-accretion is severely affected by disk eccentricity, hence detection of an eccentric protoplanetary disk in a young binary system would further constrain planet formation theories.

description: Motivated by the accumulating hints of new sterile neutrino species at the eV scale, we explore the consequences of such an hypothesis on the solar sector phenomenology. After introducing the theoretical formalism needed to describe the MSW conversion of solar neutrinos in the presence of one (or more) sterile neutrino state(s) located "far" from the (nu_1,nu_2) "doublet", we perform a quantitative analysis of the available experimental results, focusing on the electron neutrino mixing. We find that the present data posses a sensitivity to the amplitude of the lepton mixing matrix element U_e4 --- encoding the admixture of the electron neutrino with a new mass eigenstate --- which is comparable to that achieved on the standard matrix element U_e3. In addition, and more importantly, our analysis evidences that, in a 4-flavor framework, the current preference for |U_e3|>0 is indistinguishable from that for |U_e4|>0, having both a similar statistical significance (which is ~ 1.3 sigma adopting the old reactor fluxes determinations, and ~ 1.8 sigma using their new estimates). We also point out that, differently from the standard 3-flavor case, in a 3+1 scheme the Dirac CP-violating phases cannot be eliminated from the description of solar neutrino conversions.

description: „La vie avant tout“ („Zuerst das Leben“) ist die Ausstellung im Versailler Museum Espace Richaud betitelt, die im Sommer/Herbst 2021 die Fotografien zeigt, die Willy Ronis 1967 in der DDR aufgenommen hat. Sie ist als Einladung zu verstehen, die Bilder eines der wichtigsten Repräsentanten der französischen Fotografie kennenzulernen. Ronis bereiste die DDR für einige Wochen und erarbeitete aus seinen Fotografien eine in Frankreich vielfach (nicht aber in Ost- oder Westdeutschland) gezeigte Ausstellung. Doch seitdem sind nur wenige dieser Bilder in der Öffentlichkeit zu sehen gewesen. Die aktuelle Versailler Ex­po­si­ti­on und der Katalog sind eine Rekonstruktion dieser Ausstellung nach mehr als fünfzig Jahren. Die Fotografien zeigen nicht nur den fotografischen Ansatz von Willy Ronis und seine Bildsprache, sondern sie erweisen sich bei näherer Betrachtung auch als zeithistorische Quelle und als widerspenstiges Dokument kultureller Aneignung auch jenseits des Kalten Kriegs.

description: We introduce a real-space exact renormalization group method to find exactly solvable quantum spin chains and their ground states. This method allows us to provide a complete list for exact solutions within SU(2) symmetric quantum spin chains with $S\leq 4$ and nearest-neighbor interactions, as well as examples with S=5. We obtain two classes of solutions: One of them converges to the fixed points of renormalization group and the ground states are matrix product states. Another one does not have renormalization fixed points and the ground states are partially ferromagnetic states.

On Conformal Infinity and Compactifications of the Minkowski Space

Year: 2010
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Using the standard Cayley transform and elementary tools it is reiterated that the conformal compactification of the Minkowski space involves not only the "cone at infinity" but also the 2-sphere that is at the base of this cone. We represent this 2-sphere by two additionally marked points on the Penrose diagram for the compactified Minkowski space. Lacks and omissions in the existing literature are described, Penrose diagrams are derived for both, simple compactification and its double covering space, which is discussed in some detail using both the U(2) approach and the exterior and Clifford algebra methods. Using the Hodge * operator twistors (i.e. vectors of the pseudo-Hermitian space H_{2,2}) are realized as spinors (i.e., vectors of a faithful irreducible representation of the even Clifford algebra) for the conformal group SO(4,2)/Z_2. Killing vector fields corresponding to the left action of U(2) on itself are explicitly calculated. Isotropic cones and corresponding projective quadrics in H_{p,q} are also discussed. Applications to flat conformal structures, including the normal Cartan connection and conformal development has been discussed in some detail.

High-temperature high-pressure calorimetry for studying thermochemical energy storage materials
Creators: name: Hu, Ke
Publisher: name: University of British Columbia
Year: 2019

description: Metal hydrides that can hydrogenate and dehydrogenate reversibly at high-temperature and high-pressure are considered candidate materials for thermochemical energy storage (TES). The thermodynamic and kinetic properties of these metal hydrides are poorly defined due to the limitation of the measurement techniques at high-temperature and high pressure. This thesis describes a custom-designed high-temperature and high-pressure calorimeter for studying gram-scale heterogeneous chemical reactions that expands the limits of TES research. Chapter 2 outlines the physical design and fabrication details of the calorimeter. The calorimeter was demonstrated operating up to at least 1232 °C while under pure hydrogen pressures up to 33 bar with simultaneous in-situ calorimetric and pressure measurements. A finite element analysis (FEA) model was constructed using COMSOL Multiphysics to aid the experimental design. Chapter 3 outlines a thermal analysis algorithm that is modelled with a lumped-element model. The chemical enthalpy can be estimated using this algorithm along with the power and temperature profile data from this calorimeter. The model was verified using an aluminum heat of fusion experiment, as well as an exothermic process simulation to obtain a fitting accuracy of over 99%. Chapter 4 summarizes this work and offers future directions of the research that can be conducted using this instrument.
Efimov Trimers in a Harmonic Potential

description: We study the Efimov effect in a harmonic oscillator in the hyperspherical formulation, and show how a reduced model allows for a description that is a generalization of the Efimov effect in free space and leads to results that are easily interpreted. Efimov physics may be observed by varying the value of the scattering length, since in the regime where the trimers have a mixed harmonic oscillator and Efimov character, the inelastic properties of these states are still manageable. The model also allows for the study of non-universal Efimov trimers by including the effective range scattering parameter. While we find that in a certain regime the effective range parameter can take over the role of the three-body parameter, interestingly, we obtain a numerical relationship between these two parameters different from what was found in other models.

description: Many-body effects are at the very heart of diverse phenomena found in condensed-matter physics. One striking example is the Mott insulator phase where conductivity is suppressed as a result of a strong repulsive interaction. Advances in cold atom physics have led to the realization of the Mott insulating phases of atoms in an optical lattice, mimicking the corresponding condensed matter systems. Here, we explore an exotic strongly-correlated system of Interacting Dual Mott Insulators of bosons and fermions. We reveal that an inter-species interaction between bosons and fermions drastically modifies each Mott insulator, causing effects that include melting, generation of composite particles, an anti-correlated phase, and complete phase-separation. Comparisons between the experimental results and numerical simulations indicate intrinsic adiabatic heating and cooling for the attractively and repulsively interacting dual Mott Insulators, respectively.

description: Recent observations have shown that in many exoplanetary systems the spin axis of the parent star is misaligned with the planet's orbital axis. These have been used to argue against the scenario that short-period planets migrated to their present-day locations due to tidal interactions with their natal discs. However, this interpretation is based on the assumption that the spins of young stars are parallel to the rotation axes of protostellar discs around them. We show that the interaction between a magnetic star and its circumstellar disc can (but not always) have the effect of pushing the stellar spin axis away from the disc angular momentum axis toward the perpendicular state and even the retrograde state. Planets formed in the disc may therefore have their orbital axes misaligned with the stellar spin axis, even before any additional planet-planet scatterings or Kozai interactions take place. In general, magnetosphere--disc interactions lead to a broad distribution of the spin--orbit angles, with some systems aligned and other systems misaligned.

Radial transport of refractory inclusions and their preservation in the dead zone

description: Calcium-aluminum-rich inclusions (CAIs) are the oldest solar system solids known in primitive meteorites (chondrites). They predate the other components by 1-2 Myr, and likely condensed within a short time interval, close to the Sun in the gaseous protoplanetary disk. Their preservation must counterbalance both the sunward drift caused by gas drag and the general inward motion of the entraining gas. We propose that an efficient outward transport of CAIs can be achieved by advection as a result of the viscous expansion of the disk, provided it is initially less than 10 AU in size, which we argue is plausible from both observational and theoretical points of view. Gas drag would stop this outward motion within $10^5$ yr. However, by that time, a magnetically dead zone would have developed as gravitational instabilities fade away, which would trap CAIs for a significant fraction of the disk lifetime because of the reduced advection velocities. The dead zone would also prevent outward diffusion of subsequently condensed CAIs, contributing to their observed narrow age range. This preservation mechanism is independent of the outward transport scenario (before the dead zone formation) and a natural consequence of considering the source of turbulence in accretion disks.

The politics of the post-2009 financial sector regulatory reforms in the United States
Creators: name: Sutton, Brent A
Publisher: name: University of British Columbia
Year: 2019

description: This dissertation is composed of three papers analyzing the post-2009 financial sector regulatory reforms in the United States. All three papers use process tracing to perform qualitative analysis. Evidence for my analysis in part comes from contemporaneous media reports, congressional hearings, and speeches and memoirs of key participants. In addition, about 50 interviews were conducted in Fall 2018, mostly in Washington, D.C. The first paper asks why the reforms brought about only incremental rather than transformational change given the obvious failures of the pre-crisis structure and an angry public demanding change. I argue that the need to restore the confidence of institutional investors in bank securities limited the types of policies that policymakers were willing to consider. The next two papers focus on particular regulations that were stronger than expected given strong bank opposition: capital adequacy rules for U.S. globally systemically important banks (G-SIBs) and the Volcker Rule. The second paper argues that the U.S. policymakers adopted capital adequacy rules for large banks exceeding international standards because they believed they were necessary to make banks safer but, also, that they would not undermine their international competitiveness. This paper counters the claim that the globalization of financial markets prevents countries from adopting regulations that exceed international standards. My third paper examines the Volcker Rule, a signature part of the Dodd-Frank Act that prohibits banks from engaging in proprietary trading and severely restricts investments in hedge and private equity funds. I argue the Volcker Rule was adopted because proponents were able to exploit veto points in the policymaking process. The result is different from most of the existing literature on veto points, which show how they tend to inhibit policy change. The final two papers find that factors widely believed to limit policy change may do so only under certain conditions. Specifically, concerns about international competitiveness and the ability of policy opponents to use veto points to block policy change do not always prevent regulatory change from occurring.

description: We study the effect of dark matter (DM) particles in the Sun, focusing in particular on the possible reduction of the solar neutrinos flux due to the energy carried away by DM particles from the innermost regions of the Sun, and to the consequent reduction of the temperature of the solar core. We find that in the very low-mass range between 4 and 10 GeV, recently advocated to explain the findings of the DAMA and CoGent experiments, the effects on neutrino fluxes are detectable only for DM models with very small, or vanishing, self-annihilation cross section, such as the so-called asymmetric DM models, and we study the combination of DM masses and Spin Dependent cross sections which can be excluded with current solar neutrino data. Finally, we revisit the recent claim that DM models with large self-interacting cross sections can lead to a modification of the position of the convective zone, alleviating or solving the solar composition problem. We show that when the `geometric' upper limit on the capture rate is correctly taken into account, the effects of DM are reduced by orders of magnitude, and the position of the convective zone remains unchanged.

description: Topological phases of matter are described universally by topological field theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg field theories. We propose that topological insulators in two and three dimensions are described by a version of abelian $BF$ theory. For the two-dimensional topological insulator or quantum spin Hall state, this description is essentially equivalent to a pair of Chern-Simons theories, consistent with the realization of this phase as paired integer quantum Hall effect states. The $BF$ description can be motivated from the local excitations produced when a $π$ flux is threaded through this state. For the three-dimensional topological insulator, the $BF$ description is less obvious but quite versatile: it contains a gapless surface Dirac fermion when time-reversal-symmetry is preserved and yields "axion electrodynamics", i.e., an electromagnetic $E \cdot B$ term, when time-reversal symmetry is broken and the surfaces are gapped. Just as changing the coefficients and charges of 2D Chern-Simons theory allows one to obtain fractional quantum Hall states starting from integer states, $BF$ theory could also describe (at a macroscopic level) fractional 3D topological insulators with fractional statistics of point-like and line-like objects.

description: The tidal stirring model envisions the formation of dwarf spheroidal (dSph) galaxies in the Local Group via the tidal interaction of disky dwarf systems with a larger host galaxy like the Milky Way. These progenitor disks are embedded in extended dark halos and during the evolution both components suffer strong mass loss. In addition, the disks undergo the morphological transformation into spheroids and the transition from ordered to random motion of their stars. Using collisionless N-body simulations we construct a model for the nearby and highly elongated Sagittarius (Sgr) dSph galaxy within the framework of the tidal stirring scenario. Constrained by the present known orbit of the dwarf, the model suggests that in order to produce the majority of tidal debris observed as the Sgr stream, but not yet transform the core of the dwarf into a spherical shape, Sgr must have just passed the second pericenter of its current orbit around the Milky Way. In the model, the stellar component of Sgr is still very elongated after the second pericenter and morphologically intermediate between the strong bar formed at the first pericenter and the almost spherical shape existing after the third pericenter. This is thus the first model of the evolution of the Sgr dwarf that accounts for its observed very elliptical shape. At the present time there is very little intrinsic rotation left and the velocity gradient detected along the major axis is almost entirely of tidal origin. We model the recently measured velocity dispersion profile for Sgr assuming that mass traces light and estimate its current total mass within 5 kpc to be 5.2 x 10^8 M_sun. To have this mass at present, the model requires that the initial virial mass of Sgr must have been as high as 1.6 x 10^10 M_sun, comparable to that of the Large Magellanic Cloud, which may serve as a suitable analog for the pre-interaction, Sgr progenitor.

description: In this comment we explain the discrepancies mentioned by the authors between their results and ours about the influence of the gravitational quadrupole moment in the perturbative calculation of corrections to the precession of the periastron of quasielliptical Keplerian equatorial orbits around a point mass. The discrepancy appears to be consequence of two different calculations of the angular momentum of the orbits.

Improved Superconducting Qubit Readout by Qubit-Induced Nonlinearities

description: In dispersive readout schemes, qubit-induced nonlinearity typically limits the measurement fidelity by reducing the signal-to-noise ratio (SNR) when the measurement power is increased. Contrary to seeing the nonlinearity as a problem, here we propose to use it to our advantage in a regime where it can increase the SNR. We show analytically that such a regime exists if the qubit has a many-level structure. We also show how this physics can account for the high-fidelity avalanchelike measurement recently reported by Reed {\it et al.} [arXiv:1004.4323v1].

description: We consider the problem of quantifying the Pareto optimal boundary in the achievable rate region over multiple-input single-output (MISO) interference channels, where the problem boils down to solving a sequence of convex feasibility problems after certain transformations. The feasibility problem is solved by two new distributed optimal beamforming algorithms, where the first one is to parallelize the computation based on the method of alternating projections, and the second one is to localize the computation based on the method of cyclic projections. Convergence proofs are established for both algorithms.

description: We investigate key electrical properties of monolayer graphene assembled by chemical-vapor-deposition (CVD) as impacted by supporting substrate material. Graphene field-effect transistors (GFETs) were fabricated with carbon channel placing directly on hexagonal boron nitride (h-BN) and SiO2, respectively. Small-signal transconductance (gm) and effective carrier mobility (μeff) are improved by 8.5 and 4 times on h-BN, respectively, as compared with that on SiO2. Compared with GFET with exfoliated graphene on SiO2, gm and μeff measured from device with CVD graphene on h-BN substrate exhibits comparable values. The experiment demonstrates the potential of employing h-BN as a platform material for large-area carbon electronics.

The theorem was discovered while we were studying Calculus in the ”Mathematics 2” course at the USAC/CUNOC University in Quetzaltenango, Guatemala, between 2002 and 2003. The identity arose from some equations involving the relationship between delta and epsilon for polynomials, in some definitions of calculus, and Newton’s binomial theorem. The finished work won a prize in a demonstration contest at a university science fair, to which we were invited, at Rafael Landivar University on June 13, 2003.
