description: This paper outlines how a discrete choice experiment (DCE) can be used to learn more about how students are willing to trade off various features of assignments such as the nature and timing of feedback and the method used to submit assignments. A DCE identifies plausible levels of the key attributes of a good or service and then presents the respondent with alternative bundles of these attributes and their levels and asks the respondent to choose between particular bundles. We report results from a DCE we conducted with undergraduate business students regarding their preferences for assignment systems. We find that the most important features of assignments are how relevant the assignments are for exam preparation and the nature of the feedback that students receive. We also find that students generally prefer online to paper assignments. We argue that the DCE approach has a lot of potential in education research.

description: We associate to a filtration of a graded linear series of a big line bundle a concave function on the Okounkov body whose law with respect to Lebesgue's measure describes the asymptotic distribution of the jumps of the filtration. As a consequence we obtain a Fujita-type approximation theorem in this general filtered setting. We then specialize these results to filtrations by minima in the usual context of Arakelov geometry, thereby obtaining in a simple way a natural construction of an arithmetic Okounkov body, the existence of the arithmetic volume as a limit and the arithmetic Fujita approximation theorem for adelically normed graded linear series. We also obtain by a variant of this construction a short proof of the existence of the sectional capacity.

description: Cobalt-containing deposits from Cobalt carbonyl are experimentally produced and their composition is measured. The Cobalt concentration is found to be readily tunable between 20 and 70 at.% by variation of the dwell time. The variations in metallic concentration are explained by co-deposition of hydrocarbons present in the chamber background pressure.

title: Impact of Sample Size and Variability on the Power and Type I Error Rates of Equivalence Tests: A Simulation Study
Creators: name: Rusticus, Shayna A.

Publisher: name: University of Massachusetts Amherst

description: The question of equivalence between two or more groups is frequently of interest to many applied researchers. Equivalence testing is a statistical method designed to provide evidence that groups are comparable by demonstrating that the mean differences found between groups are small enough that they are considered practically unimportant. Few recommendations exist regarding the appropriate use of these tests under varying data conditions. A simulation study was conducted to examine the power and Type I error rates of the confidence interval approach to equivalence testing under conditions of equal and non-equal sample sizes and variability when comparing two and three groups. It was found that equivalence testing performs best when sample sizes are equal. The overall power of the test is strongly influenced by the size of the sample, the amount of variability in the sample, and the size of the difference in the population. Guidelines are provided regarding the use of equivalence test Accessed 20,707 times on https://pareonline.net from August 16, 2014 to December 31, 2019.

description: Hepatitis E is a zoonotic disease that is widespread in pigs and potentially severe in humans. Transmission between pigs occurs via the faecal-oral route, either by direct contact or via the environment. In addition, the main factor of propagation between farms is the transport of live animals. The pig production chain consists of many interconnected actors who form a complex network in space and time. This study aimed to test control scenarios at a national scale by considering the many transmission routes and movements of live animals. Pig movements from 2017-2020 provided by the French national pig traceability database (BDporc) were analysed. Exponential random-graph models were fitted for three subsets defined by the type of animals transported (sows, piglets or growing pigs) to estimate probabilities of contact between farms. The results were validated using cross validation of goodness-of-fit analysis and maps. The estimated contact probabilities and general characteristics of farms were used to build a demographic model that simulated pig movements at three levels − between pens, between production sectors and between farms − according to a deterministic schedule, but with random destinations weighted by the contact probabilities. Finally, the simulated dynamics were used to feed a multi-level stochastic epidemiological model that simulated within- and between-farm transmission. The prevalence of hepatitis E virus -positive pigs shipped to the slaughterhouse was estimated for different control scenarios to evaluate the effectiveness of biosecurity measures implemented at the farm level.
Compression of fibrous peat

Publisher: name: University of British Columbia
Year: 2011

description: Peat is well known for the engineering problems it poses especially in the field of settlement analysis. his This mainly because the process and therefore the factors affecting secondary settlement are as yet little understood. A preliminary laboratory investigation was carried out to examine the relationship between settlement and load for fibrous peat using different load increment rat i os and load durations. Three load increment ratios were used (3.0; 1.0; 0.33) and two durations of load (15 mins and 24 hours). The tests were performed in a consolidation apparatus using fixed rings 2.50 ins inside diameter and 0.750 ins in height. Undisturbed specimens were cut from one horizontal layer of a lump sample of fibrous peat having a water content of 1100% Within the limits of this preliminary investigation the main conclusions were: (1) all load increment ratios and load durations gave very similar settlement - log p or e-log p curves providing settlement was measured at the 100% primary consolidation point. (2) the rate of secondary settlement was independent of load increment ratio and load duration except for the type ii curve which appeared to be affected by the duration of the previous load increment. (3) only one test (#2, l.i.r. 0.33, l.d. 24 hours) gave a type ii settlement. log time curve. curve type appeared to depend on both load increment ratio and load duration or rate of loading. this test also took about 10 times as long to reach the 100% primary consolidation point. (4) the hypothesis of a unique settlement-log p curve at 100% primary consolidation for the load cycle regardless of previous loading history appeared to offer a plausible general interpretation of the results of the test series.

description: The ground-state fidelity has been introduced recently as a tool to investigate quantum phase transitions. Here, we apply this concept in the context of a crossover problem. Specifically, we calculate the fidelity susceptibility for the BCS ground-state wave function, when the intensity of the fermionic attraction is varied from weak to strong in an interacting Fermi system, through the BCS-BEC crossover. Results are presented for contact and finite-range attractive potentials and for both continuum and lattice models. We conclude that the fidelity susceptibility can be useful also in the context of crossover problems.

description: Non-perturbative Hamiltonian light-front quantum field theory presents opportunities and challenges that bridge particle physics and nuclear physics. Fundamental theories, such as Quantum Chromodynmamics (QCD) and Quantum Electrodynamics (QED) offer the promise of great predictive power spanning phenomena on all scales from the microscopic to cosmic scales, but new tools that do not rely exclusively on perturbation theory are required to make connection from one scale to the next. We outline recent theoretical and computational progress to build these bridges and provide illustrative results for nuclear structure and quantum field theory. As our framework we choose light-front gauge and a basis function representation with two-dimensional harmonic oscillator basis for transverse modes that corresponds with eigensolutions of the soft-wall AdS/QCD model obtained from light-front holography.

description: We calculate the magnetic dipole moment of the Delta(1232) and Omega^- baryons with 2+1-flavors of clover fermions on anisotropic lattices using a background magnetic field. This is the first dynamical calculation of these magnetic moments using a background field technique. The calculation for Omega^- is done at the physical strange quark mass, with the result in units of the physical nuclear magneton mu_Omega^-= -1.93(8)(12) (where the first error is statistical and the second is systematic) compared to the experimental number: -2.02(5). The Delta has been studied at three unphysical quark masses, corresponding to pion mass m_pi = 366, 438, and 548 MeV. The pion mass dependence is compared with the behavior obtained from chiral effective field theory.

description: We outline an interferometric scheme for the detection of bi-mode and multi-mode spatial entanglement of finite-temperature,interacting Bose gases of fixed particle number. Whether entanglement is present in the gas depends on the existence of the single-particle reduced density matrix between different regions of space. We apply the scheme to the problem of a harmonically trapped boson pair and show that while entanglement is rapidly decreasing with temperature, a significant amount remains for all interaction strengths at zero temperature.Thus, by tuning the interaction parameter, the distribution of entanglement between many spatial modes can be modified.

Publisher: name: University of British Columbia
Year: 2011

description: A detailed discussion of the consolidation process of peats is presented with suggested testing procedures for determining the consolidation characteristics, specific gravity, void ratio, moisture content, side friction and permeability. Particular attention is directed to secondary consolidation effects which are discussed with reference to test results on two types of peats. The results from ten consolidation tests consisting of seven tests (2.5 inches diameter by 1 inch original height) on two types of peat, and three tests (8 inches diameter by 5 inches original height) on an amorphous peat are presented. A side friction measuring apparatus is described and experimental results of side friction measurements are presented. A pore pressure probe is described and evaluated as to experimental results of pore pressure measurements, permeability measurements and a rapid method of pore pressure determination during secondary compression. A graphical method of separation of primary and secondary compression is presented and described. Three topics are outlined as possible future research that will increase the understanding of the consolidation characteristics of peat.

description: We introduce a measure of ''quantumness'' for any quantum state in a finite dimensional Hilbert space, based on the distance between the state and the convex set of classical states. The latter are defined as states that can be written as a convex sum of projectors onto coherent states. We derive general properties of this measure of non-classicality, and use it to identify for a given dimension of Hilbert space what are the "Queen of Quantum" states, i.e. the most non-classical quantum states. In three dimensions we obtain the Queen of Quantum state analytically and show that it is unique up to rotations. In up to 11-dimensional Hilbert spaces, we find the Queen of Quantum states numerically, and show that in terms of their Majorana representation they are highly symmetric bodies, which for dimensions 5 and 7 correspond to Platonic bodies.

The Effectiveness of Term Spread as a Predictor of Recessions
Creators: name: Zhu, Haoran
Publisher: name: University of Chicago
Year: 2023

description: This paper is relevant for evaluating the probability of an impending recession following multiple yield curve inversions in 2022. Evidence of an oncoming recession is of great interest, as policymakers may respond by adjusting monetary and fiscal policy while market participants may utilize it to assess investment risks. Forecasts of impending recession also interest households and businesses for financial planning in the near term. My results show that the yield curve spread for the sample period from 1972 to 2022 exhibits strong predictive power for recessions that occurred during the 1970s and early 1980s. However, the yield curve spread of the post-1997 sample has much less predictive power. The real yield including the TIPs yield and inflation-adjusted yield does not seem to have stronger predictive power than nominal yields, which needs further analysis due to the limit of sample size and measurement error. Overall, the yield curve spread is still an effective predictor of recessions. Particularly, adding the term spread in addition to recession indicator variables yields a better in-sample fit.

description: Limited streamer chambers are extensively used for high-energy and nuclear physics experiments in accelerator and underground laboratories. The tracking system of LVD, an underground experiment to study muons and neutrino astronomy, will use roughly 15.000 limited streamer chambers and 100.000 external pickup strips with digital readout electronics, In this article we discuss the different aspects of chamber operation that serve to estabilish a testing procedure and to define acceptance criteria for selecting reliable and long-life devices. The procedures and the results obtained from a long-term test to evaluate streamer chember quality, based upon a sample of 2900 items, are described. The selection tests and the long-term observations have been performed in the Astra laboratory, established at the Laboratori Nazionali di Frascati to carry out quality control procedures for streamer chambers on a large scale and in a controlled environment.

description: Time-dependent frequency harmonic oscillators (TDFHO's) are studied through the theory of Lie systems. We show that they are related to a certain kind of equations in the Lie group SL(2,R). Some integrability conditions appear as conditions to be able to transform such equations into simpler ones in a very specific way. As a particular application of our results we find t-dependent constants of the motion for certain one-dimensional TDFHO's. Our approach provides an unifying framework which allows us to apply our developments to all Lie systems associated with equations in SL(2,R) and to generalise our methods to study any Lie system.
Tunable Excitons in Biased Bilayer Graphene

description: Recent measurements have shown that a continuously tunable bandgap of up to 250 meV can be generated in biased bilayer graphene [Y. Zhang et al., Nature 459, 820 (2009)], opening up pathway for possible graphene-based nanoelectronic and nanophotonic devices operating at room temperature. Here, we show that the optical response of this system is dominated by bound excitons. The main feature of the optical absorbance spectrum is determined by a single symmetric peak arising from excitons, a profile that is markedly different from that of an interband transition picture. Under laboratory conditions, the binding energy of the excitons may be tuned with the external bias going from zero to several tens of meV's. These novel strong excitonic behaviors result from a peculiar, effective ``one-dimensional'' joint density of states and a continuously-tunable bandgap in biased bilayer graphene. Moreover, we show that the electronic structure (level degeneracy, optical selection rules, etc.) of the bound excitons in a biased bilayer graphene is markedly different from that of a two-dimensional hydrogen atom because of the pseudospin physics.

In the energy range where dose equivalents are almost constant, suitable average values are suggested to be used for practical purposes.

description: The microcanonical fermionic average method has been used so far in the context of lattice models with phase transitions at finite coupling. To test its applicability to asymptotically free theories, we have implemented it in two-dimensional QED, i.e., the Schwinger model. We exploit the possibility, intrinsic to this method, of studyng the whole \\beta,m plane without extra computer cost, to follow constant physics trajectories and measure the
m-0 limit of the chiiral condensate. We recover the continuum result within three decimal places. Moreover, the possibility, intrinsic to the method, of performing simulations directly in the chiral limit allows us to compute the average plaquette energy at m=0, the result being in perfect agreement with the expected value.
Predictions from a stochastic polymer model for the MinDE dynamics in E.coli

description: The spatiotemporal oscillations of the Min proteins in the bacterium Escherichia coli play an important role in cell division. A number of different models have been proposed to explain the dynamics from the underlying biochemistry. Here, we extend a previously described discrete polymer model from a deterministic to a stochastic formulation. We express the stochastic evolution of the oscillatory system as a map from the probability distribution of maximum polymer length in one period of the oscillation to the probability distribution of maximum polymer length half a period later and solve for the fixed point of the map with a combined analytical and numerical technique. This solution gives a theoretical prediction of the distributions of both lengths of the polar MinD zones and periods of oscillations -- both of which are experimentally measurable. The model provides an interesting example of a stochastic hybrid system that is, in some limits, analytically tractable.

Within supersymmetric models effects as large as O(10^{-4}) are possible, but only in a restricted range of the relevant parameters.

description: We discuss how to construct genuine CP-odd observables at the LHC. We classify the observables according to the even and odd properties under the naive T-transformation (\hat{T}). There are two classes of observables of our interests: CP-odd and \hat{T}-even; CP-odd and \hat{T}-odd. We expect them to have broad applications to many processes in theories beyond Standard Model with CP violation. For the purpose of illustration, we use simple example of W+W- production and subsequent decays at the LHC, where the CP violation effects are parameterized by effective CP-violating operators of WWZ coupling. We find significant sensitivity to the CP-odd couplings.

Effect of plane strain on pore pressure parameters
Creators: name: Mittal, Hari Krishan
Publisher: name: University of British Columbia

description: A theoretical as well as a laboratory investigation into the effects of plane strain on pore pressure parameters is presented. Other observations relative to stress-strain relationships, intermediate principal stress values and shear strength parameters (c´ø´) in terms of effective stresses are also reported. Experimental work consisted of the following three types of Undrained Triaxial tests with pore pressure measurements: (1) Standard triaxial tests on cylindrical specimens. (2) Triaxial tests on rectangular specimens. (3) Confined tests on rectangular specimens, in which lateral expansion was prevented in one direction, to achieve plane strain condition. A strain-controlled triaxial machine equipped with a non-flow null indicating type pore pressure measuring device was used for all shear tests. The observed data show that for the soil tested the values of pore pressure ,parameter A[subscript]f and shear strength parameter (c´ø´) under plane strain condition are higher than those obtained in corresponding triaxial tests. Failure is observed to occur, in the case of plane strain tests, at strains much smaller than those for the corresponding triaxial tests.

description: Cloud-based storage services, such as Amazon S3, provide scalable and cost-effective solutions for storing and managing large amounts of data. The approach for developing a .NET and C# program that can directly upload files to Amazon S3, helps to leverage the AWS SDK for .NET. We highlight the key technologies used in this approach, including C#, Visual Studio, AWS SDK for .NET, AWS S3 Bucket, and AWS access key and secret access key credentials. We discuss the benefits of using a cloud-based storage service like Amazon S3, such as durability, scalability, and cost-effectiveness. We provide insights into the implementation and features available in the AWS SDK for .NET for uploading files to Amazon S3. Finally, we present a step-by-step guide on how to develop a .NET and C# program that can directly upload files to Amazon S3, along with best practices for secure file upload. This approach enables developers to leverage the power of Amazon S3 for efficiently managing files in cloud-based applications, providing a scalable and reliable solution for storing and retrieving files in the cloud.

description: This paper studies spinor two-point functions for spin-1/2 and spin-3/2 fields in maximally symmetric spaces such as de Sitter spacetime, by using intrinsic geometric objects. The Feynman, positive- and negative-frequency Green functions are then obtained for these cases, from which we eventually display the supercommutator and the Peierls bracket under such a setting in two-component-spinor language.

description: "As you are well aware, many in the RHIC community are interested in the LHC heavy-ion program, but have several questions: What can we learn at the LHC that is qualitatively new? Are collisions at LHC similar to RHIC ones, just with a somewhat hotter/denser initial state? If not, why not? These questions are asked in good faith, and this talk is an opportunity to answer them directly to much of the RHIC community." With these words, the organizers of Quark Matter 2009 in Knoxville invited me to discuss the physics opportunities for heavy ion collisions at the LHC without recalling the standard arguments, which are mainly based on the extended kinematic reach of the machine. In response, I emphasize here that lattice QCD indicates characteristic qualitative differences between thermal physics in the neighborhood of the critical temperature (T_c < T < 400 - 500 MeV) and thermal physics at higher temperatures (T > 400-500 MeV), for which the relevant energy densities will be solely attainable at the LHC.

description: A candidate < 3 Jupiter mass, extrasolar planet was recently imaged by Kalas et al. (2008) using HST/ACS at 12.7" (96 AU) separation from the nearby (d = 7.7 pc) young (~200 Myr) A2V star Fomalhaut. Here we report results from M-band (4.8 micron) imaging of Fomalhaut on 5 Dec 2006 using the Clio IR imager on the 6.5-m MMT with the adaptive secondary mirror. Our images are sensitive to giant planets at orbital radii comparable to the outer solar system (~5-40 AU). Comparing our 5-sigma M-band photometric limits to theoretical evolutionary tracks for substellar objects, our results rule out the existence of planets with masses greater than 2 Jupiter masses, from ~13-40 AU and objects greater than 13 Jupiter masses from ~8-40 AU.

description: One possibility for Beyond Standard Model physics is a new strongly-interacting gauge theory. One way to determine if a non-abelian gauge theory is QCD-like or conformal is to measure the running of the renormalized gauge coupling. We define the renormalized coupling from Wilson loop ratios, and measure these ratios via lattice simulations. We test this method in SU(3) pure gauge theory and show some first results for simulations with dynamical fermions in the fundamental representation.

title: RateMyProfessors com versus formal in-class student evaluations of teaching

Year: 2007

description: Using data for 426 instructors at the University of Maine, we examined the relationship between RateMyProfessors.com (RMP) indices and formal in-class student evaluations of teaching (SET). The two primary RMP indices correlate substantively and significantly with their respective SET items: RMP overall quality correlates r = .68 with SET item, Overall, how would you rate the instructor?; and RMP ease correlates r = .44 with SET item, How did the work load for this course compare to that of others of equal credit? Further, RMP overall quality and RMP ease each correlates with its corresponding SET factor derived from a principal components analysis of all 29 SET items: r = .57 and .51, respectively. While these RMP/SET correlations should give pause to those who are inclined to dismiss RMP indices as meaningless, the amount of variance left unexplained in SET criteria limits the utility of RMP. The ultimate implication of our results, we believe, is that higher education institutions should make their SET data publicly available online.

description: In this work we present the analysis of the x-ray-absorption spectra at the silicon L2,3 and K edges in amorphous SiO2 and a quartz. This analysis consists in the comparison between experimental data and several calculations based on multiple scattering theory. An extensive discussion is presented concerning the role of the final state potential needed to reproduce the experimental data. In paticular, the effects of the cluster-size, exchange-correlation potential and the role played by self-consistent-field potential are discussed. The remarkable agreement between the theoretical computations and the experimental data allows us to identify the origin of the different features in the x-ray-absorption near-edge structure spectra.

description: Each state is required by the No Child Left Behind Act to report the percents of its students who have reached a score level called “proficient” or above for certain grades in the content areas of reading (or a similar construct) and math.  Using 2005 data from public web sites of states and the National Assessment of Educational Progress (NAEP), state-to-state differences in percents were analyzed, both unconditionally and conditionally on NAEP, for (1) trend across content areas (horizontal moderation), (2) trend across grade levels (vertical moderation), and (3) consistency with NAEP.  While there was considerable variation from state to state, especially on an idealistic-realistic dimension, the results generally show that states are relatively consistent in trends across grades and contents.

description: We report on the ultralow�??temperature resonant�??mass gravitational�??wave detector NAUTILUS, operating at the Frascati INFN Laboratories. The present aim of this detector is to achieve a sensitivity sufficient to detect bursts of gravitational radiation from sources located in our Galaxy and in the local group. Progress in transducer technology is likely to lead to sensitivities that will enable us to observe events from sources as far away as the Virgo cluster of galaxies. We describe the cryogenic apparatus, readout system, cosmic�??ray veto system, and give first results obtained during one year of continuous operation at T=0.1K. In particular the Brownian noise of the detector at T=0.1 K was measured. The measured strain sensitivity was  |6 10�??22 Hz�??1/2 at the frequencies of the two modes, 908 Hz and 924 Hz, with bandwidths of about 1 Hz.

description: The problem of many holes in a coaxial beam pipe is studied by means of the modified Bethe theory. The electromagnetic fields propagating in the coaxial region couple the equivalent dipole moments of the holes. The effect of the coupling on the longitudinal impedance and on the loss factor is investigated, showing that the interference phenomena are significant for such geometries.
