description: We demonstrate coherent control of two nuclear spins mediated by the magnetic resonance of a hyperfine-coupled electron spin. This control is used to create a double nuclear coherence in one of the two electron spin manifolds, starting from an initial thermal state, in direct analogy to the creation of an entangled (Bell) state from an initially pure unentangled state. We identify challenges and potential solutions to obtaining experimental gate fidelities useful for quantum information processing in this type of system.

description: This dissertation investigated selected processes involving baryons and nuclei in hard scattering reactions. Through these processes, this work explored the constituent structure of baryons and the mechanisms through which the interactions between these constituents ultimately control the selected reactions. First, hard nucleon-nucleon elastic scattering was studied considering the quark exchange (QE) between the nucleons to be the dominant mechanism of interaction in the constituent picture. It was found that an angular asymmetry exhibited by proton-neutron (pn) elastic scattering data is explained within this framework if a quark-diquark picture dominates the nucleon's structure instead of a more traditional SU(6) model. The latter yields an asymmetry around 90 deg center of mass scattering with a sign opposite to what is experimentally observed. The second process is the hard breakup by a photon of a nucleon-nucleon system in light nuclei. Proton-proton (pp) and pn breakup in 3He, and double Delta-isobars production in deuteron breakup were analyzed in the hard rescattering model (HRM), which in conjunction with the QE mechanism provides a QCD description of the reaction. Cross sections for both channels in 3He photodisintegration were computed without the need of a fitting parameter. The results presented here for pp breakup show excellent agreement with recent experimental data. In double Delta-isobars production in deuteron breakup, HRM angular distributions for the two double Delta channels were compared to the pn channel and to each other. An important prediction from this study is that the Delta++ Delta- channel consistently dominates Delta+Delta0, which is in contrast with models that unlike the HRM consider a double Delta system in the initial state of the interaction. For such models both channels should have the same strength.

description: A systematic procedure for deriving the master equation of a dissipative system is reported in the framework of stochastic description. For the Caldeira-Leggett model of the harmonic-oscillator bath, a detailed and elementary derivation of the bath-induced stochastic field is presented. The dynamics of the system is thereby fully described by a stochastic differential equation and the desired master equation would be acquired with statistical averaging. It is shown that the existence of a closed-form master equation depends on the specificity of the system as well as the feature of the dissipation characterized by the spectral density function. For a dissipative harmonic oscillator it is observed that the correlation between the stochastic field due to the bath and the system can be decoupled and the master equation naturally comes out. Such an equation possesses the Lindblad form in which time dependent coefficients are determined by a set of integral equations. It is proved that the obtained master equation is equivalent to the well-known Hu-Paz-Zhang equation based on the path integral technique. The procedure is also used to obtain the master equation of a dissipative harmonic oscillator in time-dependent fields.

description: We present a physically motivated explanation for the observed, monotonic increase in slope, and the simultaneous (and also monotonic) decrease in the width/scatter of the Leavitt Law (the Cepheid Period-Luminosity (PL) relation) as one systematically moves from the blue and visual into the near and mid-infared. We calibrate the wavelength-dependent, surface-brightness sensitivities to temperature using the observed slopes of PL relations from the optical through the mid-infrared, and test the calibration by comparing the theoretical predictions with direct observations of the wavelength dependence of the scatter in the Large Magellanic Cloud Cepheid PL relation. In doing so we find the slope of the Period-Radius (PR) relation is c = 0.724 +/- 0.006. Investigating the effect of differential reddening suggests that this value may be overestimated by as much as 10%; however the same slope of the PR relation fits the (very much unreddened) Cepheids in IC1613, albeit with lower precision. The discussion given is general, and also applies to RR Lyrae stars, which also show similarly increasing PL slopes and decreasing scatter with increasing wavelength.

description: Road collisions are disasters that constitute a major cause of disability and untimely death. Therefore, the need for investigation of the conditions of road collisions and driver awareness on highways is critical. A great deal of huge data, with regards to road collisions such as collision properties, road conditions, temporal information, environmental attributes, spatial measures and road geometry have been accumulated. This thesis proposes a new fuzzy granular decision tree to generate road collision rules to apply to the discrete and continuous data stored in collision databases. To improve the efficiency of the algorithm, the fuzzy rough set feature selection is applied .The major highways in California are considered as a case study to examine the proposed approach. The experimental results demonstrate that the proposed method is more accurate and efficient than the traditional decision tree methods, with the less redundancy in constructing the decision tree.

description: Being the very first in the category of low-cost consumer-level depth sensors, the recent release of Microsoft Kinect has opened the door to a new generation of computer vision and biometric security applications. This thesis focuses on designing new methodologies for Kinect-based gait and action recognition systems that utilize the Kinect 3D virtual skeleton to construct effective and robust motion representations. The proposed gait recognition method focuses on designing a feature descriptor that can capture person-specific distinct motion patterns, caused by the influence of human physiology and behavioral traits. On the other hand, the proposed action recognition method involves constructing a person-independent feature descriptor that can suppress person-specific motion traits while highlighting a more generic and high level description of action-specific skeletal joint movements. Extensive experiments with three recently released public benchmark databases demonstrate the effectiveness of the proposed methodologies, compared against state-of-the-art gait and action recognition methods.

description: The capacity of the mature adult brain to adapt following experience is limited. One means by which the adult brain can undergo plastic change is through the generation of new neurons, a process referred to as neurogenesis. Adult hippocampal neurogenesis (AHN) occurs in the subgranular zone of the dentate gyrus, can be modulated by experience, and has important implications for learning/memory and disease treatment. Experiences rarely occur in isolation and understanding the interacting effects of several modulators is necessary to fully harness potential therapeutic effects of AHN. We examined the combined effects of several modulators including chronic perinatal and adulthood exposure to selective serotonin reuptake inhibitor fluoxetine, social isolation, synaptic zinc and environmental enrichment. Our results emphasize the complexity of modulation of AHN by experience, suggest that synaptic zinc is necessary for the positive modulation of AHN, and imply that this process may be maximally modulated in the hippocampus.

molecular genetics diagnosis

description: Glycogen storage disease type I (GSD I) is a relatively rare metabolic disease with variable clinical intensity. It is caused by deficient activity of the glucose 6-phosphatase enzyme (GSD Ia) or a deficiency in the microsomal transport proteins for glucose 6-phosphate (GSD Ib). We searched the most recent English literature (1997-2017) regarding any article with the key word of “glycogen storage disease type I” in PubMed, Science Direct, Scopus, EMBASE, and Google Scholar. We will present all of the published articles about the molecular genetic characteristics and old-to-new diagnostic methods used to identify GSD I in regard of methodology, advantages and disadvantages. Diagnosis of GSD type I and its variants is challenging because it is a genetically heterogeneous disorder. Many molecular methods have been used to diagnose GSD I most of which have been based on mutation detection. Therefore, we discuss complete aspects of all of the molecular diagnostic tests, which have been used in GSD type I so far. With the advent of high throughput advanced molecular tests, molecular diagnosis is going to be an important platform for the diagnosis of storage and metabolic diseases such as GSD type I. Next-generation sequencing, in combination with the biochemical tests and clinical signs and symptoms create an accurate, reliable and feasible method. It can overcome the difficulties by the diagnosis of diseases with broad clinical and genetic heterogeneity.

description: This paper examines the long-term impacts of the joint prawn-rice gher farming system on agricultural and household incomes, soil fertility, and productivity of modern variety (MV) rice in southwestern Bangladesh, based on socioeconomic data of the gher farmers and soil fertility data of their gher plots. In 2005, 20 farmers operating on 30 plots were randomly selected from the Bilpabla village of Khulna from whom prawn and MV rice production data were collected using a questionnaire; soil samples were also collected and tested. In 2011 and 2017, the sustainability of the gher system over time was assessed through another survey of farmers following the same methodology. Results revealed that although the nominal income from gher farming increased by 59 percent in 2011 and 23 percent in 2017, the real income and per capita household income remained unchanged over time. Agricultural income has contributed about 65 percent to household income, which for gher farmers was about 200 percent higher than average rural incomes in Bangladesh. Rice productivity declined slightly from its 2005 level. However, the productivity of MV rice under prawn-rice gher farming is substantially higher than in the conventional MV rice farming system. The positive estimates of the Mean Soil Quality Index and Soil Degradation Index for land used for MV paddy production within the gher indicate an increase in soil nutrients. This suggests that the joint prawn-rice gher farming system is relatively sustainable, having improved soil fertility and stabilized real income. Policy implications toward promoting agricultural growth in the southwestern region of Bangladesh include research on developing varieties of MV rice suited to prawn-rice gher farming and the development of commercial feeds and markets for prawn to further raise productivity and incomes of gher farmers.

description: We examine various notions related with the optimality for entanglement witnesses arising from Choi type positive linear maps. We found examples of optimal entanglement witnesses which are non-decomposable, but which are not `non-decomposable optimal entanglement witnesses' in the sense of [M. Lewenstein, B. Kraus, J. Cirac, and P. Horodecki, Phys. Rev. A 62, 052310 (2000)]. We suggest to use the term `PPTES witness' and `optimal PPTES witness' in the places of `non-decomposable entanglement witness' and `non-decomposable optimal entanglement witnesses' in order to avoid possible confusion. We also found examples of non-extremal optimal entanglement witnesses which are indecomposable.

Recoding the Creative City: Calgary's Changing Relationship with the Arts
Creators: name: Turner, Elysia
Publisher: name: Graduate Studies
Year: 2016
Subjects: subject: Mass Communications
subject: Cultural Policy

description: Over the last decade, the Creative City has become a dominant paradigm, a neoliberal, and meta-narrative of how creativity can be used to economically stimulate and develop the city. The ideas behind the Creative City have influenced cultural policy-making practices around the globe and have been a driving influence in Canadian civic arts policy since its inception. From this time, Canadian cities have been transforming how they live with the arts, primarily through policy and funding practices that emphasize private over public investment, and that position the arts not as a social commitment but as an instrument of economic development. My research, which focuses on the implementation of Creative City policy in Calgary, investigates how the Creative City paradigm impacts funding practices, policymakers interpretation and definition of culture, and the ways in which it has, and continues to shape the role of the arts within the city.

description: We report the discovery of two new halo velocity groups (Cancer groups A and B) traced by 8 distant RR Lyrae stars and observed by the Palomar Transient Factory (PTF) survey at R.A.~129 deg, Dec~20 deg (l~205 deg, b~32 deg). Located at 92 kpc from the Galactic center (86 kpc from the Sun), these are some of the most distant substructures in the Galactic halo known to date. Follow-up spectroscopic observations with the Palomar Observatory 5.1-m Hale telescope and W. M. Keck Observatory 10-m Keck I telescope indicate that the two groups are moving away from the Galaxy at v_{gsr} = 78.0+-5.6 km/s (Cancer group A) and v_{gsr} = 16.3+-7.1 km/s (Cancer group B). The groups have velocity dispersions of σ_{v_{gsr}}=12.4+-5.0 km/s and σ_{v_{gsr}}=14.9+-6.2 km/s, and are spatially extended (about several kpc) making it very unlikely that they are bound systems, and are more likely to be debris of tidally disrupted dwarf galaxies or globular clusters. Both groups are metal-poor (median metallicities of [Fe/H] = -1.6 dex and [Fe/H] =-2.1 dex), and have a somewhat uncertain (due to small sample size) metallicity dispersion of ~0.4 dex, suggesting dwarf galaxies as progenitors. Two additional RR Lyrae stars with velocities consistent with those of the Cancer groups have been observed ~25 deg east, suggesting possible extension of the groups in that direction.

description: A simple method to create and control magnetic potentials onto coupled quantum wells is demonstrated for indirect-exciton magnetic confinement. Localized inhomogeneous magnetic potentials with periodically distributed local minima and maxima, known as magnetic lattices, are projected into the plane of the coupled quantum wells and used for the spatially distributed two-dimensional indirect-exciton trapping, in which case localized indirect-excitons are observed. The indirect-exciton trapping mechanism is examined by controlling external magnetic field bias resulting in a shift of the localized excitonic lattice.
The Load Response of the Rabbit Medial Collateral Ligament Femoral Enthesis

description: The enthesis is the attachment of ligament/tendon to bone and is one of nature’s solutions to the challenge of transferring load between dissimilar materials. Frequently injured and repaired, the healing enthesis fails to regain the properties that made it effective initially, highlighting the importance of understanding how it behaves mechanically. One of the essential barriers to date in doing so has been the visualization of the enthesis under load, a result stemming primarily from their small size. This project aims to overcome this obstacle through the use of specialized loading equipment, sample preparation and laser scanning microscopy. Further, finite element models were created to assess potential explanations for the observed behaviour. To our knowledge, this is the first time the enthesis has been simultaneously loaded and visualized at a level of detail corresponding to individual fibrils. Additional study may benefit from the established methodology and suggested mechanisms of load transfer.
$k$-MLE: A fast algorithm for learning statistical mixture models

Subjects: subject: Machine Learning (cs.LG)

description: We describe $k$-MLE, a fast and efficient local search algorithm for learning finite statistical mixtures of exponential families such as Gaussian mixture models. Mixture models are traditionally learned using the expectation-maximization (EM) soft clustering technique that monotonically increases the incomplete (expected complete) likelihood. Given prescribed mixture weights, the hard clustering $k$-MLE algorithm iteratively assigns data to the most likely weighted component and update the component models using Maximum Likelihood Estimators (MLEs). Using the duality between exponential families and Bregman divergences, we prove that the local convergence of the complete likelihood of $k$-MLE follows directly from the convergence of a dual additively weighted Bregman hard clustering. The inner loop of $k$-MLE can be implemented using any $k$-means heuristic like the celebrated Lloyd's batched or Hartigan's greedy swap updates. We then show how to update the mixture weights by minimizing a cross-entropy criterion that implies to update weights by taking the relative proportion of cluster points, and reiterate the mixture parameter update and mixture weight update processes until convergence. Hard EM is interpreted as a special case of $k$-MLE when both the component update and the weight update are performed successively in the inner loop. To initialize $k$-MLE, we propose $k$-MLE++, a careful initialization of $k$-MLE guaranteeing probabilistically a global bound on the best possible complete likelihood.

description: Although damage control (DC) surgery may improve survival in select, severely injured patients, the procedure is associated with significant morbidity, and therefore should only be used when appropriately indicated. The objective of this thesis was to identify and evaluate candidate indications for use of DC surgery and DC interventions in civilian trauma patients. We conducted a scoping review to identify candidate indications. Among 27,732 citations identified by the search, we included 270 articles that reported 1,107 indications for DC surgery and 424 indications for 16 DC interventions. We conducted a content analysis to synthesize these indications into 123 named, content-characteristic codes representing unique indications for DC surgery and 101 codes representing unique indications for DC interventions. An international panel of trauma surgery experts (n=9) subsequently assessed 101 (82.1%) of the coded indications for DC surgery and 78 (77.2%) of the coded indications for DC interventions to be appropriate. We conducted a systematic review to identify studies reporting data on the reliability or validity of indications or that assessed outcomes associated with utilization of an indication or indications or the conduct of DC versus definitive surgery for one or more indications. Among 31,014 citations identified, we included 36 studies that evaluated 79 unique indications. Of these, 19 had evidence of face validity or predictive criterion validity, six had evidence supporting that they were associated with improved survival when utilized or when DC was conducted instead of definitive surgery, and three had evidence suggesting that they were associated with reduced survival which may be improved with DC surgery. Finally, we conducted a cross-sectional survey of trauma centers and surgeons located in the United States, Canada, and Australasia. In total, 232 (64.8%) trauma centers responded. These centers nominated 366 surgeons to survey about indications for DC surgery, of whom 201 (56.0%) responded. Respondents assessed 15 (78.9%) preoperative and 23 (95.8%) intraoperative indications to be appropriate. The list of candidate indications for use of DC surgery and DC interventions identified in this thesis may provide a practical foundation to guide surgical practice while studies are conducted to evaluate their impact on patient outcomes.

The likelihood analysis of the combined data sample, which corresponds to a total of 1.8 x 10**14 muon decays, gives a 90% C.L. upper limit of 2.4 x 10**-12 on the branching ratio of the mu->e gamma decay, constituting the most stringent limit on the existence of this decay to date.

description: We consider the problem of a spreading ground water mound of liquid in a porous medium, situated on an impermeable horizontal solid layer. The mathematical formulation for this problem is given by the modified porous medium equation. We derive a global condition in form of an energy integral, describing the loss of liquid in the porous medium. This yields the necessary condition that determines the similarity exponents for the similarity solution of second kind, describing the long time behavior of the mound. We further apply our method to the problem when instead of an energy integral another conservation law, such as the first moment integral, obeyed by a family of antisymmetric solutions, is violated. Here, we consider as an application the problem of the impact of a flood infiltrating a porous medium. In all cases we will also solve and compare our analytical results with our numerical solution, and, if available, with examples existing in the literature.

description: We consider the problem of active feedback control of rbc via shadowgraphic measurement. Our theoretical studies show, that when the feedback control is positive, i.e. is tuned to advance the onset of convection, there is a critical threshold beyond which the system becomes linearly ill-posed so that short-scale disturbances are greatly amplified. Experimental observation suggests that finite size effects become important and we develop a theory to explain these contributions. As an efficient modelling tool for studying the dynamics of such a controlled pattern forming system, we use a Galerkin approximation to derive a dimension reduced model.

description: Academic administrators are challenged by a multiplicity of factors that impact both the current and the future operations of post-secondary institutions (PSIs). Issues, such as scarcity of funds, combined with the economic realities of the labour force, drive the need for change and promote that research is vital to inform strategies and fortify the responses of academic administrators. Utilizing the case study method, this research explored two post-secondary sites located in the geographic area of Calgary, Alberta. The work, underpinned primarily by Constructive Alignment Theory (Biggs, 1996) and supported by Curriculum Process Theory (Stenhouse, 1975) prompted the disquieting discovery in the findings that there was a clear discontinuity in the culture between the polytechnic institute and the university. The notion of the Ecosystem of Relevance was offered. Further, discussion to address the impact of real life elements and resources to teaching activities and assessment activities, collaboration of business schools and industry partners, collaboration of business schools with other business schools, and promotion of business school outcomes was presented. It is hoped that this work provides academic administrators the ability to more accurately inform strategies related to curriculum design and appropriate allocation of limited resources.
Acoustical modeling of the transient response of rooms using a beam-tracing model
Creators: name: Yousefzadeh, Behrooz
Publisher: name: University of British Columbia
Year: 2010

description: Two room-acoustical prediction models were previously developed in the UBC Acoustics and Noise Research Group and used for studying the steady-state responses of various room configurations. The first is a wave-based beam-tracing model for empty rooms with specularly-reflecting, extended-reaction surfaces. Room surfaces were modeled as multiple layers of elastic solid, fluid and poroelastic materials, and their acoustical properties were calculated using a transfer-matrix approach. The second model, PRAY, is a wave-based ray-tracing model which can account for fittings, diffuse surface reflection and sound diffraction. This thesis presents further development of the existing beam-tracing model, incorporating features from PRAY such as diffuse reflection. The computational efficiency of the existing model has been improved and energy-based prediction has been implemented. Both wave- and energy-based modeling have been validated against theory for the case of sound propagation above a rigid plane. The new model can predict the pressure impulse response between the source and receiver, which is required for obtaining the temporal response of rooms to other sound sources, as well as for deriving room-acoustical parameters that correlate with subjective perception of sound. The new model is used to compare the effects of different surface-reaction models on the transient response and derived room-acoustical parameters. In addition to investigating the significance of modeling room surfaces as of extended or local reaction, effects of phase changes due to surface reflections have been studied by considering real and complex reflection coefficients. Moreover, wave-based energy impulse responses and room-acoustical parameters have been compared with those obtained from energy-based modeling. Modeling of diffuse surface reflections has been implemented in the model and validated against existing experimental results. The model has been further extended to include sound diffraction around wedges based on an exact formulation. This broadens the application of the model to situations with more realistic features, such as sound propagation in fitted rooms or in long enclosures with bends, and evaluation of screen barriers in open-plan offices. The implemented diffraction model has been validated through comparison with existing results in the literature, and by comparing prediction results with experiments on a finite-length barrier over a flat surface.

description: We study the constraints imposed by conformal symmetry on the equations of fluid dynamics at second order in gradients of the hydrodynamic variables. At zeroth order conformal symmetry implies a constraint on the equation of state, E=2/3 P, where E is the energy density and P is the pressure. At first order, conformal symmetry implies that the bulk viscosity must vanish. We show that at second order conformal invariance requires that two-derivative terms in the stress tensor must be traceless, and that it determines the relaxation of dissipative stresses to the Navier-Stokes form. We verify these results by solving the Boltzmann equation at second order in the gradient expansion. We find that only a subset of the terms allowed by conformal symmetry appear.

description: We consider general quenched disordered lattice spin models on compact local spin spaces with possibly dependent disorder. We discuss their corresponding joint measures on the product space of disorder variables and spin variables in the infinite volume. These measures often possess pathologies in a low temperature region reminiscent of renormalization group pathologies in the sense that they are not Gibbs measures on the product space. Often the joint measures are not even almost Gibbs, but it is known that there is always a potential for their conditional expectations that may however only be summable on a full measures set, and not everywhere. In this note we complement the picture from the non-pathological side. We show regularity properties for the potential in the region of interactions where the joint potential is absolutely summable everywhere. We prove unicity and Lipschitz-continuity, much in analogy to the two fundamental regularity theorems proved by van Enter, Fernandez, Sokal for renormalization group transformations.
Evolution of Supernova Remnants Expanding out of the Dense Circumstellar Matter into the Rarefied Interstellar Medium

description: We carry out 3D-hydrodynamical calculations for the interaction of expanding supernova ejecta with the dense circumstellar matter (CSM) and the rarefied interstellar medium (ISM) outside. The CSM is composed of the stellar wind matter from the progenitor in its pre-supernova phase, and assumed to be axially symmetric: more matter around the equator than in the polar direction driven by rotation of the progenitor. Because of high density of the CSM, the ionization state of the shock-heated ejecta quickly becomes equilibrium with the electron temperature. When the blast wave breaks out of the CSM into the rarefied ISM, the shocked ejecta cools rapidly due to adiabatic expansion, and hence an over-ionized/recombining plasma would be left. The ejecta is reheated by the second reverse shock due to the interaction with the ISM. We calculate the emission measure of the supernova remnant (SNR) along the line of sight, and find that the over-ionized plasma appears to be bar-like with wings in the edge-on (equatorial view), while shell-like in the face-on (polar view) geometry with respect to the rotation axis. The hot gas heated by the blast wave exists in the outermost region of the SNR with a nearly complete shell, but the X-rays therefrom are too faint to be observable. Thus, depending on the viewing angle, the SNR of the over-ionized plasma would exhibit center-filled morphology in X-rays, like W49B, a mixed-morphology SNR. The bar-like structure is swept out by the second reverse shock and disappears eventually, and then the SNR becomes shell-like in both the equatorial and polar views in the later phase of the evolution.

description: Knowledge-based search is a set of concepts that can help software developers build better search systems. Until recently, developers often build sequential knowledge-based search systems (making use of only a single processor core) because sequential systems are easier to develop. For further speed improvements, developers could rely on new processors to run at a faster clock rate. However, with the recent trend in processor design, clock rates have remained stagnant while processors are moving towards having multiple processing cores. To make use of these additional processing capabilities, developers now need to {\it distribute} their search to the available processing cores. Building distributed based search systems is a difficult and time consuming process because not only are distributed systems difficult to develop, but knowledge-based search systems are not readily able to be distributed. Fortunately, there are different distribution paradigms that provide guidelines as to how the search process can be distributed. This thesis introduces DisSLib:ICA, a software library for building distributed knowledge-based search systems based on the improving on the competition approach paradigm. The main goal of DisSLib:ICA is to allow developers to build distributed search systems in the same manner, and with the same amount of effort, as it would normally take to build a sequential search system. It achieves this by handling the communication and multi-threading tasks along with providing developers a skeleton structure of a search system that can be extended to fit the developer's concrete search problem. To evaluate DisSLib:ICA, we have built three search systems that solves different problems using the library. Our results have shown that the library allows developers to build distributed systems with approximately the same amount of effort as it would take to build a sequential system. In addition, our experiments show that by using the improving on the competition approach paradigm, the library produces synergistic speedups.

description: Let $\mathcal{S}$ be the semigroup $\mathcal{S}=\sum^{\oplus k}_{i=1}\Sc{S}_i$, where for each $i\in I$, $\mathcal{S}_i$ is a countable subsemigroup of the additive semigroup $\B{R}_+$ containing 0. We consider representations of $\mathcal{S}$ as contractions $\{T_s\}_{s\in\mathcal{S}}$ on a Hilbert space with the Nica-covariance property: $T_s^*T_t=T_tT_s^*$ whenever $t\wedge s=0$. We show that all such representations have a unique minimal isometric Nica-covariant dilation. This result is used to help analyse the nonself-adjoint semicrossed product algebras formed from Nica-covariant representations of the action of $\mathcal{S}$ on an operator algebra $\mathcal{A}$ by completely contractive endomorphisms. We conclude by calculating the $C^*$-envelope of the isometric nonself-adjoint semicrossed product algebra (in the sense of Kakariadis and Katsoulis).

description: This study assesses the long-run relationship and short-run dynamics between paddy yields and climate variables, particularly maximum and minimum temperature and rainfall, using time-series data from 1971 to 2014 in Nepal. Applying Autoregressive-Distributed Lag Regression or ARDL bounds testing approach for analysis of co-integration between the variables, we confirm that there is a long-run relationship among the variables. Furthermore, we employ Granger non-causality tests for robustness. The findings reveal that rainfall has substantial effects on the rice yield. Specifically, a positive and significant relationship exists between rice yields and rainfall and that this relationship is unidirectional. Rainfall impacts on rice yield and holding all things constant, a 1 mm increase in rainfall increases rice yields by 0.65 percent. Given the effects of temperature on rice crops and increasing climate change vulnerabilities, agricultural scientists should focus on research and development of temperature tolerant rice varieties in the production of rice yields.

description: The computation of the phase shift in a symmetric atom interferometer in the presence of a gravitational field is reviewed. The difference of action-phase integrals between the two paths of the interferometer is zero for any Lagrangian which is at most quadratic in position and velocity. We emphasize that in a large class of theories of gravity the atom interferometer permits a test of the weak version of the equivalence principle (or universality of free fall) by comparing the acceleration of atoms with that of ordinary bodies, but is insensitive to that aspect of the equivalence principle known as the gravitational redshift or universality of clock rates.
