description: In this work the equation of circular loops of cosmic string possessing time-dependent tension is studied in the de Sitter spacetime. We find that the cosmic string loops with initial radius $r(t_{0})>0.707L$, L de Sitter radius, should not collapse to form a black holes. It is also found that in the case of $r(t_{0})<0.707L$ a loop of cosmic string whose tension depends on some power of cosmic time can not become a black hole if the power is lower than a critical value which is associated with the initial size of the loop.

description: Regional water scarcity has motivated the South Central Texas Regional Water Planning Group to actively develop water management plans to address long-/short-term regional water needs. This study, therefore, develops an integrated Edwards Aquifer groundwater and river system simulation model to determine the "best" choice of regional water management plans using mixed-integer linear programming. The economic, hydrologic, and environmental consequences of the "best" choice of regional and other water management plans and options are evaluated and compared. Results indicate a tradeoff between the economic and environmental benefits. A slight decrease in economic benefit results in a substantial increase in environmental benefit.
Tentative sensitivity of future $0νββ$-decay experiments to neutrino masses and Majorana CP phases

description: In the near future, the neutrinoless double-beta ($0νββ$) decay experiments will hopefully reach the sensitivity of a few ${\rm meV}$ to the effective neutrino mass $|m^{}_{ββ}|$. In this paper, we tentatively examine the sensitivity of future $0νββ$-decay experiments to neutrino masses and Majorana CP phases by following the Bayesian statistical approach. Provided experimental setups corresponding to the sensitivity of $|m^{}_{ββ}| \simeq 1~{\rm meV}$, the null observation of $0νββ$ decays in the case of normal neutrino mass ordering leads to a very competitive bound on the lightest neutrino mass $m^{}_1$. Namely, the $95\%$ credible interval turns out to be $1.6~{\rm meV} \lesssim m^{}_1 \lesssim 7.3~{\rm meV}$ or $0.3~{\rm meV} \lesssim m^{}_1 \lesssim 5.6~{\rm meV}$ when the uniform prior on $m^{}_1/{\rm eV}$ or on $\log^{}_{10}(m^{}_1/{\rm eV})$ is adopted. Moreover, one of two Majorana CP phases is strictly constrained, i.e., $140^\circ \lesssim ρ\lesssim 220^\circ$ for both priors of $m^{}_1$. In contrast, if a relatively worse sensitivity of $|m^{}_{ββ}| \simeq 10~{\rm meV}$ is assumed, the constraint becomes accordingly $0.6~{\rm meV} \lesssim m^{}_1 \lesssim 26~{\rm meV}$ or $0 \lesssim m^{}_1 \lesssim 6.1~{\rm meV}$, while two Majorana CP phases will be essentially unconstrained. In the same statistical framework, the prospects for the determination of neutrino mass ordering and the discrimination between Majorana and Dirac nature of massive neutrinos in the $0νββ$-decay experiments are also discussed. Given the experimental sensitivity of $|m^{}_{ββ}| \simeq 10~{\rm meV}$ (or $1~{\rm meV}$), the strength of evidence to exclude the Majorana nature under the null observation of $0νββ$ decays is found to be inconclusive (or strong), no matter which of two priors on $m^{}_1$ is taken.

description: Colleges of veterinary medicine are often asked to provide evidence of the economic impacts of their activities. This paper presents methods for evaluating a veterinary college and applies them to the Virginia-Maryland Regional College of Veterinary Medicine. It assesses short-run impacts on income and employment using input-output analysis. Long-run benefits are estimated using a combination of economic surplus analysis, travel cost analysis and demand estimation, animal-owner willingness-to-pay based on a survey of practicing veterinarians, and earnings differentials.

description: This paper analyses the world demand for fibers using the system-wide approach with three dimension-product X space X time. We investigate to what extent differences in international consumption patterns of fibers can be explained by differences in incomes and prices faced by different consumers. A novel approach to cross-country consumption comparisons is employed to avoid the troublesome problem of what exchange rates to use when converting data into a common currency unit. We use data from the ten largest consuming countries to estimate demand systems and then examine how they perform in predicting consumption patterns in a large number of out-of-sample countries.
Generalized string-net models: A thorough exposition

description: We describe how to construct generalized string-net models, a class of exactly solvable lattice models that realize a large family of 2D topologically ordered phases of matter. The ground states of these models can be thought of as superpositions of different "string-net configurations", where each string-net configuration is a trivalent graph with labeled edges, drawn in the $xy$ plane. What makes this construction more general than the original string-net construction is that, unlike the original construction, tetrahedral reflection symmetry is not assumed, nor is it assumed that the ground state wave function $Φ$ is "isotropic": i.e. in the generalized setup, two string-net configurations $X_1, X_2$ that can be continuously deformed into one another can have different ground state amplitudes, $Φ(X_1) \neq Φ(X_2)$. As a result, generalized string-net models can realize topological phases that are inaccessible to the original construction. In this paper, we provide a more detailed discussion of ground state wave functions, Hamiltonians, and minimal self-consistency conditions for generalized string-net models than what exists in the previous literature. We also show how to construct string operators that create anyon excitations in these models, and we show how to compute the braiding statistics of these excitations. Finally, we derive necessary and sufficient conditions for generalized string-net models to have isotropic ground state wave functions on the plane or the sphere -- a property that may be useful in some applications.

M82, Starbursts, Star Clusters, and the Formation of Globular Clusters

Year: 2005

description: We observed the nearby starburst galaxy M82 in CO in the higher frequency (2--1) transition to achieve an angular resolution below 1 arc second or 17 pc at the target. We resolved the molecular gas into a large number of compact clouds, with masses ranging from about 2x10^3 to 2x10^6 solar masses. The mass spectrum scales as N(M) ~ M^-1.5, similar to the mass spectra of young massive star clusters suggesting that individual molecular clouds are transformed in the starburst into individual star clusters. The larger clouds are surrounded by supernovae and HII regions suggesting that star formation proceeds from the outside of the clouds and progresses inward consistent with triggering by a sudden increase in external pressure. The clouds with internal star formation have velocity gradients and inverse P-Cygni spectral line profiles indicating inward motions of 35 kms consistent with shock driven compression. Diffuse free-free radio emission and X-ray emission around the clouds provides evidence for superheated ionized gas sufficient to drive the compression. Clouds with spectral lines indicating expansion show little internal star formation suggesting that the dynamics precedes and is responsible for the star formation rather than the inverse. M82 is known to be in interaction with neighboring M81. The overall picture is consistent with the formation of massive star clusters from individual giant molecular clouds crushed by a sudden galactic scale increase in external pressure generated by the changing dynamics that result from a near-collision with a neighboring galaxy. Present day globular clusters may have formed in a similar fashion in primordial galaxies.

description: This study uses a combination of computational, corpus and qualitative stylistic methods to isolate and analyse, from my own corpus of Emily Dickinson’s ‘fascicle’ poems (Miller, 2016), some syntactic and morphological markers which potentially construct the effect of an ironic authorial persona. Based on the results of a user designed set of syntactic and morphological queries performed on the corpus by a rule based NLP software package called NooJ (Silberztein, 2016), I intended to suggest ways in which selected concepts from Cognitive Grammar (Langacker, 2009) might be used to develop those computational results into a qualitative theory of how grammatical markers related to person and agency can be seen to instantiate some forms of irony.

description: Deep reinforcement learning (DRL) demonstrates great potential in mapless navigation domain. However, such a navigation model is normally restricted to a fixed configuration of the range sensor because its input format is fixed. In this paper, we propose a DRL model that can address range data obtained from different range sensors with different installation positions. Our model first extracts the goal-directed features from each obstacle point. Subsequently, it chooses global obstacle features from all point-feature candidates and uses these features for the final decision. As only a few points are used to support the final decision, we refer to these points as support points and our approach as support point-based navigation (SPN). Our model can handle data from different LiDAR setups and demonstrates good performance in simulation and real-world experiments. Moreover, it shows great potential in crowded scenarios with small obstacles when using a high-resolution LiDAR.

description: This paper contributes to the debate on whether pre-harvest pricing strategies can improve returns over cash sales at harvest. It also examines cash flow needs of such strategies. The analysis is conducted for Ohio corn produced from 1986 through 1999. The pre-harvest strategies evaluated (short futures, long put, synthetic long put, put-call fence) did not statistically improve returns over cash sales at harvest. However, if implemented during or before planting, these naïve strategies reduced the standard deviation of annual gross income. Substantial cash flow may be incurred, either to establish the strategy or meet margin calls. Therefore, assessments of pre-harvest pricing strategies should include cash flow needs, along with return and risk. Key Words: cash flow risk, pre-harvest pricing strategies, price risk.

The experiment was performed with the SKS spectrometer at KEK PS. The measured ratio of double charge exchange cross-section for these energies dsigma(0.50 GeV)/dOmega / dsigma(0.75 GeV)/dOmega = 1.7 +/- 0.2, disagrees with the value of 7.2 predicted within the conventional sequential single charge exchange mechanism. Possible reasons for the disagreement are discussed in connection with the Glauber inelastic rescatterings.

subject: FOS: Physical sciences

description: (Summary) Making use of scaling relations between the central and the total galaxy luminosity of a dark matter halo as a function of the halo mass, and the scatter in these relations, we present an empirical model to describe the luminosity function (LF) of galaxies. We extend this model to describe relative statistics of early-type, or red, and late-type, or blue, galaxies, with the fraction of early type galaxies at halo centers, relative to the total sample, determined only by the halo mass and the same fraction in the case of satellites is taken to be dependent on both the halo mass and the satellite galaxy luminosity. This simple model describes the conditional luminosity functions, LF of galaxies as a function of the halo mass, measured with the 2dF galaxy group catalog from cluster to group mass scales. Using 2dF measurements, we extract information related to conditional mass function for halos from extreme voids to dense regions in terms of the galaxy overdensity. We also calculate the probability distribution function of halo mass, as a function of the galaxy overdensity, and use these probabilities to address preferred environments of red and blue galaxies. Our model also allow us to make predictions, for example, galaxy bias as a function of the galaxy type and luminosity, the void mass function, and the average galaxy luminosity as a function of the density environment.

CMB lensing power spectrum estimation without instrument noise bias

description: The power spectrum of cosmic microwave background (CMB) lensing will be measured to sub-percent precision with upcoming surveys, enabling tight constraints on the sum of neutrino masses and other cosmological parameters. Measuring the lensing power spectrum involves the estimation of the connected trispectrum of the four-point function of the CMB map, which requires the subtraction of a large Gaussian disconnected noise bias. This reconstruction noise bias receives contributions both from CMB and foreground fluctuations as well as instrument noise (both detector and atmospheric noise for ground-based surveys). The debiasing procedure therefore relies on the quality of simulations of the instrument noise which may be expensive or inaccurate. We propose a new estimator that makes use of at least four splits of the CMB maps with independent instrument noise. This estimator makes the CMB lensing power spectrum completely insensitive to any assumptions made in modeling or simulating the instrument noise. We show that this estimator, in many practical situations, leads to no substantial loss in signal-to-noise. We provide an efficient algorithm for its computation that scales with the number of splits $m$ as $\mathcal{O}(m^2)$ as opposed to a naive $\mathcal{O}(m^4)$ expectation.

description: This study focuses on the development of a optimal harvest scheduling mathematical programming model which incorporates within-season changes in perennial crop yields. Daily crop yield prediction models are estimated econometrically for major commercially grown sugarcane cultivars. This information is incorporated into a farm-level harvest scheduling linear programming model. The harvest scheduling model solves for an optimal daily harvest schedule which maximizes whole farm net returns above harvesting costs. Model results are compared for a commercial sugarcane farm in Louisiana.

Publisher: name: Zenodo
Year: 2021

description: Our Annual Report 2020 summarises how, despite the challenges and turbulence of the past year, we have made great progress as an association together with our Members. In 2020, our association united over 50 universities of Science and Technology (S&T) from 26 countries who employed over 95,000 academic staff, educated over 1,100,000 students and were awarded over €4 billion worth of European research funding. Our dynamic network supports our Members (i) to learn from each other, (ii) to advocate their contributions and interests and (iii) to inspire key debates. Our Work Plan from 2020 to 2021 put the contribution of universities of S&T to ecological, economic and social sustainability at the heart of the activities and deliverables of our association. The over 1,000 volunteers and leaders from our Members have worked tirelessly to advance the vital contributions that research, education and innovation play in the systemic changes needed to achieve the United Nations Sustainable Development Goals. Our association has thus continued to be an active and constructive partner at the European level and contributed to major milestones, such as shaping the European Research Area, the European Education Area and the new generation of EU funding programmes. For each of our areas of work, the report summarises the activities and deliverables of our bodies, with a particular view to highlighting the contribution of our association to sustainability. David Bohmert (Secretary General) said “2020 marked an extraordinary year for universities of S&T and their students, teachers, researchers, support staff and leaders. Next to the imminent challenges and pressures on research, education and innovation of switching to online modes of working and to safeguard the health and well-being of our communities (both on-campus and off-campus), 2020 demonstrated the vital role of S&T in contributing to tackling global challenges such as the Covid-19 pandemic. “We may also not forget about the tremendous global challenges that loom behind the pandemic - whether they are cultural, ecological, economic, health-related, social or societal. “Together, our Members and association are emerging from a period of ‘survival’, focused on ensuring core operations, as (i) more directed where we have influence, (ii) more agile, (iii) diverse, (iv) sustainable and (v) resilient. The last is of course a great engineering property linked to ductility, self-healing and self-learning, all valuable features for during and after a year unlike almost any other.”

description: We study the energy flow due to the motion of topological solitons in nonlinear extended systems in the presence of damping and driving. The total field momentum contribution to the energy flux, which reduces the soliton motion to that of a point particle, is insufficient. We identify an additional exchange energy flux channel mediated by the spatial and temporal inhomogeneity of the system state. In the well-known case of a DC external force the corresponding exchange current is shown to be small but non-zero. For the case of AC driving forces, which lead to a soliton ratchet, the exchange energy flux mediates the complete energy flow of the system. We also consider the case of combination of AC and DC external forces, as well as spatial discretization effects.

description: In this paper, we investigate the double covering of modular $Γ^{}_5 \simeq A^{}_5$ group and derive all the modular forms of weight one for the first time. The modular forms of higher weights are also explicitly given by decomposing the direct products of weight-one forms. For the double covering group $Γ^\prime_5 \simeq A^\prime_5$, there exist two inequivalent two-dimensional irreducible representations, into which we can assign two right-handed neutrino singlets in the minimal seesaw model. Two concrete models with such a salient feature have been constructed to successfully explain lepton mass spectra and flavor mixing pattern. The allowed parameter space for these two minimal scenarios has been numerically explored, and analytically studied with some reasonable assumptions.

description: The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermion and the Z2 gauge flux. Detection of these excitations remains challenging, because of their fractional quantum numbers and non-locality. It was proposed recently that fingerprints of fractional excitations are encoded in the phonon spectra of Kitaev quantum spin liquids through a novel fractional-excitation-phonon coupling. Here, we uncover this effect in $α$-RuCl3 using inelastic X-ray scattering with meV resolution. At high temperature, we discover interlaced optical phonons intercepting a transverse acoustic phonon between 3 and 7 meV. Upon decreasing temperature, the optical phonons display a large intensity enhancement near the Kitaev energy, JK~8 meV, that coincides with a giant acoustic phonon softening near the Z2 gauge flux energy scale. This fractional excitation induced phonon anomalies uncover the key ingredient of the quantum thermal Hall effect in $α$-RuCl3 and demonstrates a proof-of-principle method to detect fractional excitations in topological quantum materials.

Results confirm that plantings were speculative and that economic feasibility critically impacts acreage retention as the industry matures. Prices at alternative outlets and fruit quality in storage affect monthly shipments. Flexibilities of monthly f.o.b. prices imply elastic kiwifruit demand, and imports are found to be substitutes. The industry could increase its average annual gross revenue by marketing the crop earlier in the season.
Effective Nucleon Masses in Symmetric and Asymmetric Nuclear Matter

description: The momentum and isospin dependence of the in-medium nucleon mass are studied. Two definitions of the effective mass, i.e. the Dirac mass $m^*_D$ and the nonrelativistic mass $m^*_{NR}$ which parameterizes the energy spectrum, are compared. Both masses are determined from relativistic Dirac-Brueckner-Hartree-Fock calculations. The nonrelativistic mass shows a distinct peak around the Fermi momentum. The proton-neutron mass splitting in isospin asymmetric matter is $m^*_{D,n} m^*_{NR,p}$, which is consistent with nonrelativistic approaches.

description: We used the VLA to search for 3He+ emission from two Galactic planetary nebulae (PNe): NGC6572 and J320}. Standard stellar models predict that the 3He/H abundance ratios for PNe should be 1-2 orders of magnitude higher than the primordial value (3He/H ~ 1e-5 by number) determined from Galactic HII region abundances and confirmed by WMAP cosmic microwave background results. Chemical evolution models suggest that fewer than 5% of all PNe enrich the interstellar medium (ISM) with 3He at the level of standard stellar models. Our target PNe are therefore anomalous in that they were selected from a sample deliberately biased to contain objects with properties that maximized the likelihood of a 3He detection by the VLA. We have detected the 8.665 GHz hyperfine 3He+ transition in J320 at the 4 sigma level. The 3He/H abundance ratio is 1.9e-3 with roughly a factor of two uncertainty. For NGC 6572 we find an upper limit of 3He/H <= 1e-3. This detection of 3He in J320 makes it the second PN known to have an anomalously high 3He abundance confirming that at least some low-mass stars produce significant amounts of 3He that survives to the PN stage and enriches the ISM.

description: We investigate the possibility to have electron-pairs in dephasing-free subspace (DFS), by means of the quantum-dot cellular automata (QCA) and single-spin rotations, to carry out a high-fidelity and deterministic universal quantum computation. We show that our QCA device with electrons tunneling two dimensionally is very suitable for DFS encoding, and argue that our design favors a scalable quantum computation robust to collective dephasing errors.

"Doing co-op" : student perceptions of learning and work
Creators: name: Grosjean, Garnet
Publisher: name: University of British Columbia
Year: 2009

description: This study investigates co-op education programs from the students' perspective. It details how their experience of co-op shapes students' perceptions of learning and work; and how, through these perceptions, they ultimately make meaning of their undergraduate experience. The study focuses on the unique set of social forces and relationships represented in coop education, and investigates them by means of a nested case study, utilizing a variety of data collection methods. The University of Victoria represents the first level of analysis; the co-op department the second level; four individual co-op programs comprise the third level; and co-op students the fourth level. In addition to consulting the historical and documentary record, I conducted a survey to collect data on co-op students' satisfaction with their programs, and interviewed co-op coordinators, faculty, students, and university administrators. The student interviews were 'in-depth,' exploring methods of recruitment, forms of regulation, effects of learning context, academic implications, and employment outcomes. My purpose was to understand how co-op students develop perceptions of learning and work, and how they use these perceptions to understand their experience. The study generated five key findings about co-op at UVic: (i) the co-op work term produces a 'co-op effect' that shapes students' perceptions of learning and professional work and profoundly impacts their experience of the co-op program; (ii) the power of the academic context, particularly through the setting and assessment of academic objectives, mediates co-op students' professional development; (iii) theories of cognition and situated learning indicate that learning is socially constructed in the co-op workplace, and individually constructed in the co-op classroom; (iv) learning and skill development are context-dependent and mediated by individual learning strategies; (v) perceptions formed by co-op students of what constitutes 'learning' and 'work', and of the university's role in the economy and society, can help determine whether universities are fulfilling their mandate of providing relevant higher education. Based on these findings six general conclusions about co-op can be drawn: 1) co-op education programs are a way that universities can address demands for relevant education; 2) the decision by students to participate in co-op is driven by a desire for specific employment and career outcomes; 3) the work term is a transformative experience around which students base their expectations of the co-op program; 4) participation in co-op enables students to construct meaningful learning through interpretive and experiential interactions with their social environment; 5) professional development of co-op students takes place in the workplace; and 6) co-op education is becoming an elite program. Recommendations for improvements to the development and delivery of co-op education, for policy and practice and for further research are offered.

description: Maintaining a consistent attribute profile is crucial for dialogue agents to naturally converse with humans. Existing studies on improving attribute consistency mainly explored how to incorporate attribute information in the responses, but few efforts have been made to identify the consistency relations between response and attribute profile. To facilitate the study of profile consistency identification, we create a large-scale human-annotated dataset with over 110K single-turn conversations and their key-value attribute profiles. Explicit relation between response and profile is manually labeled. We also propose a key-value structure information enriched BERT model to identify the profile consistency, and it gained improvements over strong baselines. Further evaluations on downstream tasks demonstrate that the profile consistency identification model is conducive for improving dialogue consistency.

description: Typically, marketers define market segments by their demographic characteristics, assuming that these segments represent consumers with relatively homogeneous buying patterns. A more managerially useful definition, however, groups consumers of similar behavior directly and then seeks to find demographic commonalities among them. This study uses a latent class analysis technique to segment consumers based on their responsiveness to a set of marketing variables, finding that a multiple-segment model provides a better fit to the data, and that these segments differ significantly in their responsiveness. By targeting marketing activities to their most responsive segments, the efficiency of commodity promotion can be dramatically improved.

Tailoring Dzyaloshinskii-Moriya interaction in a transition metal dichalcogenide by dual-intercalation

description: Dzyaloshinskii-Moriya interaction (DMI) is vital to form various chiral spin textures, novel behaviors of magnons and permits their potential applications in energy-efficient spintronic devices. Here, we realize a sizable bulk DMI in a transition metal dichalcogenide (TMD) 2H-TaS2 by intercalating Fe atoms, which form the chiral supercells with broken spatial inversion symmetry and also act as the source of magnetic orderings. Using a newly developed protonic gate technology, gate-controlled protons intercalation could further change the carrier density and intensely tune DMI via the Ruderman-Kittel-Kasuya-Yosida mechanism. The resultant giant topological Hall resistivity of 1.4 uohm.cm at -5.2V (about 460% of the zero-bias value) is larger than most of the known magnetic materials. Theoretical analysis indicates that such a large topological Hall effect originates from the two-dimensional Bloch-type chiral spin textures stabilized by DMI, while the large anomalous Hall effect comes from the gapped Dirac nodal lines by spin-orbit interaction. Dual-intercalation in 2HTaS2 provides a model system to reveal the nature of DMI in the large family of TMDs and a promising way of gate tuning of DMI, which further enables an electrical control of the chiral spin textures and related electromagnetic phenomena.

description: The US pork sector has experienced many significant structural changes in recent years. Such changes may have influenced price dynamics and transmission of shocks through marketing channels. We investigate linkages among farm, wholesale, and retail markets using weekly price data for the period covering 1987 through 1998. Our analysis uses a threshold cointegration model that permits asymmetric adjustment to positive and negative price shocks. Our results reveal important asymmetries. Our results are consistent with existing literature which has determined that price adjustment patterns are unidirectional and that information tends to flow from farm, to wholesale, to retail markets.
Competitive localization of vortex lines and interacting bosons

description: We present a theory for the localization of three-dimensional vortex lines or two-dimensional bosons with short-ranged repulsive interaction which are competing for a single columnar defect or potential well. For two vortices we use a necklace model approach to find a new kind of delocalization transition between two different states with a single bound particle. This exchange-delocalization transition is characterized by the onset of vortex exchange on the defect for sufficiently weak vortex-vortex repulsion or sufficiently weak binding energy corresponding to high temperature. We calculate the transition point and order of the exchange-delocalization transition. A generalization of this transition to arbitrary vortex number is proposed.

description: We report on the observation of coherent, purely collisionally driven spin dynamics of neutral atoms in an optical lattice. For high lattice depths, atom pairs confined to the same lattice site show weakly damped Rabi-type oscillations between two-particle Zeeman states of equal magnetization, induced by spin changing collisions. This paves the way towards the efficient creation of robust entangled atom pairs in an optical lattice. Moreover, measurement of the oscillation frequency allows for precise determination of the spin-changing collisional coupling strengths, which are directly related to fundamental scattering lengths describing interatomic collisions at ultracold temperatures.
