description: In celebrating Iachello's 60th birthday we underline many seminal contributions for the study of the degrees of freddom relevant for the structure of nuclei and other hadrons. A dipole degree of freedom, well described by the spectrum generating algebra U(4) and the Vibron Model, is a most natural concept in molecular physics. It has been suggested by Iachello with much debate, to be most important for understanding the low lying structure of nuclei and other hadrons. After its first observation in $^{18}O$ it was also shown to be relevant for the structure of heavy nuclei (e.g. $^{218}Ra$). Much like the Ar-benzene molecule, it is shown that molecular configurations are important near threshold as exhibited by states with a large halo and strong electric dipole transitions. The cluster-molecular Sum Rule derived by Alhassid, Gai and Bertsch (AGB) is shown to be a very useful model independent tool for examining such dipole molecular structure near thereshold. Accordingly, the dipole strength observed in the halo nuclei such as $^6He, ^{11}Li, ^{11}Be, ^{17}O$, as well as the N=82 isotones is concentrated around threshold and it exhausts a large fraction (close to 100%) of the AGB sum rule, but a small fraction (a few percent) of the TRK sum rule. This is suggested as an evidence for a new soft dipole Vibron like oscillations in nuclei.

description: Results obtained with a triple GEM detector operated in pure CF4 with and without a reflective CsI photocathode are presented. The detector operates in a stable mode at gains up to 10^4. A deviation from exponential growth starts to develop when the total charge exceeds ~ 4 10^6 e leading to gain saturation when the total charge is ~ 2 10^7 e and making the structure relatively robust against discharges. No aging effects are observed in the GEM foils after a total accumulated charge of ~ 10 mC/cm^2 at the anode. The ion back-flow current to the reflective photocathode is comparable to the electron current to the anode. However, no significant degradation of the CsI photocathode is observed for a total ion back-flow charge of ~ 7 mC/cm^2.

description: Using a symmetry-preserving regularisation of a vector$\times$vector contact interaction (SCI), we complete a systematic treatment of twelve semileptonic transitions with vector meson final states: $D\to ρ$, $D_{(s)}\to K^\ast$, $D_s\to ϕ$, $B\to ρ$, $B_s\to K^\ast$, $B_{(s)}\to D_{(s)}^\ast$, $B_c \to B_{(s)}^\ast, J/ψ, D^\ast$; and thereby finalise a unified analysis of semileptonic decays of heavy+heavy and heavy+light pseudoscalar mesons to both pseudoscalar and vector meson final states. The analysis is marked by algebraic simplicity, few parameters, and the ability to consistently describe systems from Nambu-Goldstone modes to heavy+heavy mesons. Regarding the behaviour of the transition form factors, the SCI results compare well wherever sound experimental or independent theory analyses are available; hence, the SCI branching fraction predictions should be a reasonable guide. Considering the ratios $R(D_{(s)}^{(\ast)})$, $R(J/ψ)$, $R(η_c)$, whose values are key tests of lepton universality in weak interactions, the SCI values agree with Standard Model predictions. The $B_{(s)}\to D_{(s)}^\ast$ transitions are used to predict the precursor functions that evolve into the universal Isgur-Wise function in the heavy-quark limit, with results that conform with those from other sources where such are available. The study also exposes effects on the transition form factors that flow from interference between emergent hadron mass from the strong interaction and Higgs boson couplings via current-quark masses, including flavour symmetry violation.

Fostering vocabulary growth during interactive read-alouds in the grade one classroom

Publisher: name: The University of British Columbia

description: During a six-week instructional unit in a Grade one class, I investigated students' abilities to learn specific target vocabulary during interactive read-alouds. Reading aloud to children provides a powerful context for word learning (Biemiller & Boote, 2006). Language and , specifically, vocabulary development play critical roles in early literacy development (Wasik, 2010, p.621). During interactive read-alouds, teachers can focus their students' attention to Tier 2 words - "words that are of a high frequency for mature language users and are found across a variety of domains" (Beck, McKeown, & Kucan, 2002, p.28). Knowing that active participation during interactive read-alouds is more conducive to vocabulary learning than passive listening to a dramatic reading of a story, I posed this question: Would the implementation of specific vocabulary teaching strategies in the context of interactive read-alouds improve Grade One students's vocabulary? During the read-alouds, I used various teaching strategies to teach the students 24 vocabulary words selected from 12 specific stories. Data consisted of pre and post-instructional observational notes about the students' usage of the target words, and my researcher's log. After analyzing the data I found that the students' vocabulary did improve. On average, students knew nine of the 24 words at the onset of the instructional unit and demonstrated an understanding of 18 of the 24 target words at the end of the unit. Overall, there was evidence of oral comprehension of the target words but limited expressive use of the vocabulary. It is also important to note that because this study did not use an experimental design, I cannot prove that improvements were a result of the intervention. The students' basic understanding of the target words, however, is a foundation upon which they will continue to build an increased fluency, flexibility, and knowledge of the specific vocabulary taught during the interactive read-alouds.
Journal for the 21st century : personal growth through storytelling

description: As I progress on my life journey there are several days when my inner turmoil rises from deep within and it must be dealt with. I began to write as a way of coping with some of the many issues that had been held within my mind. This paper looks at what literature has to say about the ways in which writing within a journal can lead towards personal growth. Also, the role a journal has in an individual's journey towards personal growth. I look at my journey in journal writing from a narrative inquiry perspective. I chose to write and review my stories, and uses of the journal on my journey towards personal growth. I wanted to calm the inner confusion that would often take a firm grasp during times of stress and anxiety. As I began down my path of graduate studies I kept a journal to help me cope with the many challenges that I would encounter. It is through looking at my personal experiences that I was able to find my holistic self. As a educator, and student, I believe it is best practice to integrate the medicine wheel teachings within all of my work. I looked at the importance of reconnecting myself to each aspect: physical, intellectual, emotional, and spiritual. Journaling creates a space where a person can perform however they wish; and share, or not, as much as they want about themselves. Utilizing certain methods can help bring about deep personal change. One of the most encouraging practices of journal writing is that one can use it to suit their own personal needs. This paper looks at a small amount of writing techniques that were most effective for my journal writing journey. Journal writing can become a close and personal ally as one works towards finding a connection to their whole self.

description: We derived the distance to the central region of the Sagittarius dwarf spheroidal galaxy from the Red Giant Branch Tip. The obtained distance modulus is $(m-M)_0=17.10\pm0.15$, corresponding to a heliocentric distance $D=26.30\pm1.8$ Kpc. This estimate is in good agreement with the distance obtained from RR Lyrae stars of the globular cluster M~54, located in the core of the Sgr galaxy, once the most accurate estimate of the cluster metallicity and the most recent calibration of the $M_V(RRLy) vs.[Fe/H]$ relation are adopted.

description: We find a class of approximate perturbative solutions describing multi-centered BPS black holes in asymptotically AdS$_4$. These black holes are moving coplanarly in a circular orbit with common radius but fixed phase differences, where the radius is characterized by a common boost velocity $v$. While the solutions are not complete, as they are only accurate up to $\mathcal{O}(M^2v^2)$, we are able to locally investigate their supersymmetric properties in four-dimensional $\mathcal{N} = 2$ supergravity. The result indicates that, while a single BPS black hole preserves half of the supersymmetries, a configuration with two or more black holes is only 1/4 BPS. These perturbative solutions reduce in the asymptotically Minkowski limit to the multi-black hole solution of Majumdar and Papapetrou.

description: Early to intermediate time behaviour of the planar Richtmyer--Meshkov instability (RMI) is investigated through direct numerical simulation (DNS) of the evolution of a deterministic interfacial perturbation initiated by a $\textrm{Ma}=1.84$ shock. The model problem is the well studied initial condition from the recent $θ$-group collaboration [Phys. Fluids. 29 (2017) 105107]. A grid convergence study demonstrates that the Kolmogorov microscales are resolved by the finest grid for the entire duration of the simulation, and that both integral and spectral quantities of interest are converged. Comparisons are made with implicit large eddy simulation (ILES) results from the $θ$-group collaboration, generated using the same numerical algorithm. The total amount of turbulent kinetic energy (TKE) is shown to be decreased in the DNS compared to the ILES, particularly in the transverse directions, giving rise to a greater level of anisotropy in the flow (70\% vs. 40\% more TKE in the shock parallel direction at the latest time considered). This decrease in transfer of TKE to the transverse components is shown to be due to the viscous suppression of secondary instabilities. Overall the agreement in the large scales between the DNS and ILES is very good and hence the mixing width and growth rate exponent $θ$ are very similar. There are substantial differences in the small scale behaviour however, with a 38\% difference observed in the minimum values obtained for the mixing fractions $Θ$ and $Ξ$. Differences in the late time decay of TKE are also observed, with decay rates calculated to be $τ^{-1.41}$ and $τ^{-1.25}$ for the DNS and ILES respectively.

In a self-gravitating N-body system confined in an adiabatic wall, we show that the quasi-equilibrium sequence arising from the Tsallis entropy, so-called stellar polytropes, plays an important role in characterizing the transient states away from the Boltzmann-Gibbs equilibrium state.

description: We report the synthesis of the entire $Ln$AuAl$_4$Ge$_2$ ($Ln$ = Y, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Tm) series and focus on the magnetic properties of GdAuAl$_4$Ge$_2$ and TbAuAl$_4$Ge$_2$. Temperature and magnetic field dependent magnetization, heat capacity, and electrical resistivity measurements reveal that both compounds exhibit several magnetically ordered states at low temperatures, with evidence for magnetic fluctuations extending into the paramagnetic temperature region. For magnetic fields applied in the $ab$-plane there are several ordered state regions that are associated with metamagnetic phase transitions, consistent with there being multiple nearly degenerate ground states. Despite Gd being an isotropic $S$-state ion and Tb having an anisotropic $J$-state, there are similarities in the phase diagrams for the two compounds, suggesting that factors such as the symmetry of the crystalline lattice, which features well separated triangular planes of lanthanide ions, or the Ruderman-Kittel-Kasuya-Yosida interaction as defined by the Fermi surface topography control the magnetism. We also point out similarities to other centrosymmetric compounds that host skyrmion lattices such as Gd$_2$PdSi$_3$, and propose that the $Ln$AuAl$_4$Ge$_2$ family of compounds are of interest as reservoirs for complex magnetism and electronic behaviors such as the topological Hall effect.

Optimal control theory for unitary transformations

Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The dynamics of a quantum system driven by an external field is well described by a unitary transformation generated by a time dependent Hamiltonian. The inverse problem of finding the field that generates a specific unitary transformation is the subject of study. The unitary transformation which can represent an algorithm in a quantum computation is imposed on a subset of quantum states embedded in a larger Hilbert space. Optimal control theory (OCT) is used to solve the inversion problem irrespective of the initial input state. A unified formalism, based on the Krotov method is developed leading to a new scheme. The schemes are compared for the inversion of a two-qubit Fourier transform using as registers the vibrational levels of the $X^1Σ^+_g$ electronic state of Na$_2$. Raman-like transitions through the $A^1Σ^+_u$ electronic state induce the transitions. Light fields are found that are able to implement the Fourier transform within a picosecond time scale. Such fields can be obtained by pulse-shaping techniques of a femtosecond pulse. Out of the schemes studied the square modulus scheme converges fastest. A study of the implementation of the $Q$ qubit Fourier transform in the Na$_2$ molecule was carried out for up to 5 qubits. The classical computation effort required to obtain the algorithm with a given fidelity is estimated to scale exponentially with the number of levels. The observed moderate scaling of the pulse intensity with the number of qubits in the transformation is rationalized.

description: We show, that classical Kaluza-Klein theory possesses hidden nematic dynamics. It appears as a consequence of 1+4-decomposition procedure, involving 4D observers 1-form λ. After extracting of boundary terms the, so called, "effective matter" part of 5D geometrical action becomes proportional to square of anholonomicity 3-form λ\wedge dλ. It can be interpreted as twist nematic elastic energy, responsible for elastic reaction of 5D space-time on presence of anholonomic 4D submanifold, defined by λ. We derive both 5D covariant and 1+4 forms of 5D nematic equilibrium equations, consider simple examples and discuss some 4D physical aspects of generic 5D nematic topological defects.

description: The dynamics of two-dimensional (2D) topological quadrupole insulator (TQI) and Chern insulator (CI) after the real-space configuration is transformed from a cylinder or Mobius strip to open boundary condition (OBC) and vice versa is analyzed. Similar dynamics of both models are observed, but the quadrupole corner states of the TQI makes the signatures more prominent. After the systems transform from a cylinder or Mobius strip to OBC, the occupation of the corner state of the TQI and the edge state of the CI exhibits steady-state behavior. The steady-state values depend on the ramping rate of the configuration transformation, manifesting a type of quantum memory effect. On the other hand, oscillatory density ripples from the merging of edge states persist after the systems transform from OBC to a cylinder or Mobius strip. If the final configuration is a cylinder, the density ripples are along the edges of the cylinder. In contrast, the density ripples can traverse the bulk after the systems transform from OBC to a Mobius strip. The transformation of real-space topology thus can be inferred from the dynamical signatures of the topological edge states.

description: We study a model of a large number of strongly coupled phonons that can be viewed as a bosonic variant of the Sachdev-Ye-Kitaev model. We determine the phase diagram of the model which consists of a glass phase and a disordered phase, with a first-order phase transition separating them. We compute the specific heat of the disordered phase, with which we diagnose the high-temperature crossover to the classical limit. We further study the real-time dynamics of the disordered phase, where we identify three dynamical regimes as a function of temperature. Low temperatures are associated with a semiclassical regime, where the phonons can be described as long-lived normal modes. High temperatures are associated with the classical limit of the model. For a large region in parameter space, we identify an intermediate-temperatures regime, where the phonon lifetime is of the order of the Planckian time scale $\hbar/k_B T$.

description: Globally, over half of all sorghum is used for human consumption. Yet sorghum is largely unknown as a food in the United States and other developed countries. Recently, the U.S. demand for sorghum as a gluten-free, non-GMO input to food products has been growing. At the same time, the use of sorghum for food and industrial uses is being promoted by the producer-financed United Sorghum Checkoff Program (USCP). How much of that growth can be attributed to the USCP promotion? Has the investment been profitable for sorghum producers? This study finds that USCP promotion programs have resulted in a 4% increase in the sales value of sorghum for that purpose and a 1% increase in total sorghum farm revenue. The farm level benefit-cost ratio is estimated at between 5.8 and 7.1 in terms of producer profit per dollar spent on promotion.

description: We investigate a dynamical mass generation mechanism for the off-diagonal gluons and ghosts in SU(N) Yang-Mills theories, quantized in the maximal Abelian gauge. Such a mass can be seen as evidence for the Abelian dominance in that gauge. It originates from the condensation of a mixed gluon-ghost operator of mass dimension two, which lowers the vacuum energy. We construct an effective potential for this operator by a combined use of the local composite operators technique with the algebraic renormalization and we discuss the gauge parameter independence of the results. We also show that it is possible to connect the vacuum energy, due to the mass dimension two condensate discussed here, with the non-trivial vacuum energy originating from the condensate , which has attracted much attention in the Landau gauge.

$W$ boson mass tension caused by its right-handed gauge coupling at high energies?

description: The CDF collaboration's recent high-precision measurement of the $W$mass is in $7.0~σ$ disagreement with the Standard Model expectation. This tension will be relieved if the $W$ boson has a non-trivial right-handed gauge coupling at high energies. At TeV scales, the SM gauge symmetric four-fermion interactions induce a right-handed gauge coupling, and SM fermions compose massive composite particles. We investigate the top-quark mass produced by spontaneous symmetry breaking and compute the $W$ and $Z$ boson propagators and decays. The right-handed coupling corrections to their masses and widths are consistent with experimental measurements. We discuss how SM gauge bosons and composite particles can restore parity-preserving gauge symmetries at TeV scales.

description: The history of galaxy formation via star formation and stellar mass assembly rates is now known with some certainty, yet the connection between high redshift and low redshift galaxy populations is not yet clear. By identifying and studying individual massive galaxies at high-redshifts, z > 1.5, we can possibly uncover the physical effects driving galaxy formation. Using the structures of high-z galaxies, as imaged with the Hubble Space Telescope, we argue that it is now possible to directly study the progenitors of ellipticals and disks. We also briefly describe early results that suggest many massive galaxies are forming at z > 2 through major mergers.

description: This paper deals with a detail study of gravitational collapse of dust and viscous fluids under the assumptions of spherical symmetry. Our main goal is to closely analyze the horizons which arise during this gravitational phenomenon. To this end, we examine the formation and evolution of trapped surfaces in these spacetimes, with special attention to trapped regions and cylinders foliated by marginally trapped surfaces. The time evolution of trapped surfaces, collapsing shell as well as the event horizon are identified analytically as well as numerically. Using different density profiles of matter, we analyze, how the nature of the marginally trapped surfaces modify as we change the energy momentum tensor. These studies reveal that depending on the mass function and the mass profile, it is possible to envisage situations where dynamical horizons, timelike tubes or isolated horizons may arise.

description: It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volume, leading to a badly divergent gravitational path integral. Not even in dimension 2, where a non-perturbative quantum gravity theory can be constructed explicitly from a (regularized) path integral, has this problem found a satisfactory solution. -- In the present work, we extend a previous 2d Lorentzian path integral, regulated in terms of Lorentzian random triangulations, to include space-times with an arbitrary number of handles. We show that after the imposition of physically motivated causality constraints, the combined sum over geometries and topologies is well-defined and possesses a continuum limit which yields a concrete model of space-time foam in two dimensions.

description: Objectives: To examine Plate Waste (PW) from elementary and middle school-aged children by school and by grade when grapes were on the lunch menu versus when they were absent. The primary hypothesis tested was that grapes enhance consumption and lessen plate waste, thereby serving as a “gateway” fruit to healthier eating. The foods examined were selected fruits, vegetables, and entrées. The endpoints of analysis included lost dollars and lost nutrients (calories, fat, sodium, protein, and fiber.) Methods: In two elementary schools and two middle schools from one school district (ISD) in Texas, PW of food items served on the school lunch menu was calculated for all students collectively by grade, enabling comparisons between the two school levels. Results: Findings suggest that when the food environment included grapes, consumption of healthier menu items increased, while consumption of less healthy menu items decreased. On grape days, lost dollars per serving of vegetables was lower compared to non-grape days. This difference was significantly different from zero. Intakes of effective calories, fat, sodium, protein, and fiber per serving of entrées, vegetables and fruits on grape days were higher versus non-grape days, and differences were statistically significant. Conclusions: The presence of grapes had a positive impact regarding the school lunch eating behaviors of children. PW of entrée, fruit, and vegetable items impacted nutrient consumption as well as wasted dollars –considerations for school foodservice.

description: Purpose: The availability of evidence-based therapies for abstract words is limited. Abstract Semantic Associative Network Training (AbSANT) is theoretically motivated and has been shown to not only improve directly trained abstract words, such as the word emergency in the category hospital, but also promote generalization to related concrete words, such as the word doctor.Method: This tutorial provides step-by-step instructions, including cueing strategies, and material resources for conducting AbSANT. Importantly, this tutorial also explains the theoretical motivation behind AbSANT, as well as information regarding the population, dose, and environment characteristics of effective trials, to help clinicians make informed decisions regarding the applicability of this approach and to guide decision-making throughout the steps of therapy.Conclusions: AbSANT is an effective, theoretically based treatment for abstract words. This tutorial provides all of the resources needed to conduct AbSANT with clients with aphasia.

description: Chiral Higher Spin Gravity with cosmological constant is constructed as a Free Differential Algebra, i.e. at the level of equations of motion, which is a smooth deformation of its flat space cousin arXiv:2205.07794. Chiral Higher Spin Gravity is a unique class of local higher spin theories; its very existence implies that there is a closed and, most likely, integrable sub-sector of Chern-Simons Matter Theories, which has important consequences both for the theories themselves and for three-dimensional bosonization duality.

Asymptotic expansions close to the singularity in Gowdy spacetimes

description: We consider Gowdy spacetimes under the assumption that the spatial hypersurfaces are diffeomorphic to the torus. The relevant equations are then wave map equations with the hyperbolic space as a target. In an article by Grubisic and Moncrief, a formal expansion of solutions in the direction toward the singularity was proposed. Later, Kichenassamy and Rendall constructed a family of real analytic solutions with the maximum number of free functions and the desired asymptotics at the singularity. The condition of real analyticity was subsequently removed by Rendall. In an article by the author, it was shown that one can put a condition on initial data that leads to asymptotic expansions. In this article, we show the following. By fixing a point in hyperbolic space, we can consider the hyperbolic distance from this point to the solution at a given spacetime point. If we fix a spatial point for the solution, it is enough to put conditions on the rate at which the hyperbolic distance tends to infinity as time tends to the singularity in order to conclude that there are smooth expansions in a neighbourhood of the given spatial point.

description: In many environments, only a relatively small subset of the complete state space is necessary in order to accomplish a given task. We develop a simple technique using emergency stops (e-stops) to exploit this phenomenon. Using e-stops significantly improves sample complexity by reducing the amount of required exploration, while retaining a performance bound that efficiently trades off the rate of convergence with a small asymptotic sub-optimality gap. We analyze the regret behavior of e-stops and present empirical results in discrete and continuous settings demonstrating that our reset mechanism can provide order-of-magnitude speedups on top of existing reinforcement learning methods.

description: Plate waste, defined as the quantity of edible food left uneaten after a meal, is a challenge for schools participating in the National School Lunch Program (NSLP). The new nutrition standards in the NSLP of United States Department of Agriculture (USDA) were implemented at the beginning of school year (SY) 2012-2013. School foodservice authorities were concerned that the new standards would result in increased plate waste and reduced participation, especially by students who paid full prices for lunch. There are many reasons for plate waste, including students’ dislike of the foods served, the composition of meals, the environment in which students are eating, the lack of time to eat, or perhaps other factors. The objective of this study was to examine the relationship between entrée/vegetable “pairings” and plate waste by elementary school students pre- and post-implementation of the new school meal standards. Plate waste was measured to determine which entrée/vegetable pairs produced the least amount of waste. Plate waste of 144 and 305 entrée/vegetable pairings was analyzed, pre- and post-implementation, respectively. Our results indicated that more nutritious meals were offered during the post-implementation period. The new school meal standards led to no significant changes in entrée plate waste, but vegetable plate waste increased by 5.6%. As such, increases in the combined entrée/vegetable plate waste were evident from 40.4% pre-implementation to 43.5% post-implementation. The top five vegetables in terms of popularity were all starchy vegetables, the majority of which were potatoes in various processed forms. The least popular vegetables were dark-green leafy vegetables, such as steamed broccoli, both pre- and post-implementation. Chicken nuggets were the most popular entrée and were wasted the least. Understanding the dynamics of food pairings and providing desirable entrée and vegetable pairings can help reduce waste from school lunches.

description: We introduce a Z_2-graded version of the nonlinear Schrodinger equation that includes one fermion and one boson at the same time. This equation is shown to possess a supersymmetry which proves to be itself part of a super-Yangian symmetry based on gl(1|1). The solution exhibits a super version form of the classical Rosales solution. Then, we second quantize these results, and give a Lax pair formulation (based on gl(2|1)) for the model.

description: The U.S. cotton industry operates a government- established program to enhance the profitability of U.S. cotton production through generic advertising and promotional activities intended to expand the demand for cotton. Operated by the Cotton Board, the so-called cotton checkoff program is financed by an assessment on domestic cotton sales and imports that amounted to nearly $75 million in 2007. How effective is the cotton checkoff program in expanding cotton demand? Are cotton producers and importers better off as a result of the program? That is, are the benefits to those who pay for the program greater than the costs? We analyze the answers to these questions using a modified version of the Texas Tech University World Fiber Model. We report the key average annual impacts of the checkoff program on U.S. and foreign cotton and man-made fiber and associated textile markets. Using those results we calculate the benefit-cost ratio (BCR) to producers and importers from their payments into the checkoff program. The annual return to producers averaged $5.7 in benefit per dollar of cost and $14.4 per dollar of cost to importers over the 1986/87 to 2004/05 period of analysis. The higher importer BCR reflects gains not only from additional sales of cotton fiber textiles but also from the “spillover” effects on sales of man-made fiber textiles prompted by the cotton checkoff program. The results also show that U.S. taxpayers are better off because the cotton checkoff program tends to reduce government outlays directed to cotton farmers.
