description: In 1944, Marschak and Andrews published a seminal paper on how to obtain consistent estimates of a production technology. The original formulation of the econometric model regarded the joint estimation of the production function together with the first-order necessary conditions for profit-maximizing behavior. In the seventies, with the advent of duality theory, the preference seemed to have shifted to a dual approach. Recently, however, Mundlak resurrected the primal-versus-dual debate with a provocative paper titled “Production Function Estimation: Reviving the Primal.” In that paper, the author asserts that the dual estimator, unlike the primal approach, is not efficient because it fails to utilize all the available information. In this paper we argue that efficient estimates of the production technology can be obtained only by jointly estimating all the relevant primal and dual relations. Thus, the primal approach of Mundlak and the dual approach of McElroy become nested special cases of our general specification. The theory of the price-taking cost-minimizing, risk-neutral firm is based upon the expectation of prices and quantities as the relevant information used by the entrepreneur in making her decisions. The econometrician intervenes later on and collects information about those quantities and prices. In so doing, measurement errors creep into the econometric specification. A two-phase procedure is suggested to implement the primal-dual approach. A Monte Carlo analysis indicates that our primal-dual approach produces estimates that exhibit a smaller variance of the estimates than those obtained from either the traditional primal or the dual specification separately implemented. A bootstrapping approach is used to compute the standard errors of the model’s estimates.

description: This paper introduces a new form of real-time affective interface that engages the user in a process of conceptualisation of their emotional state. Inspired by Barrett's Theory of Constructed Emotion, `Mirror Ritual' aims to expand upon the user's accessible emotion concepts, and to ultimately provoke emotional reflection and regulation. The interface uses classified emotions -- obtained through facial expression recognition -- as a basis for dynamically generating poetry. The perceived emotion is used to seed a poetry generation system based on OpenAI's GPT-2 model, fine-tuned on a specially curated corpus. We evaluate the device's ability to foster a personalised, meaningful experience for individual users over a sustained period. A qualitative analysis revealed that participants were able to affectively engage with the mirror, with each participant developing a unique interpretation of its poetry in the context of their own emotional landscape.

description: We first review some invariant theoretic results about the finite subgroups of SU(2) in a quick algebraic way by using the McKay correspondence and quantum affine Cartan matrices. By the way it turns out that some parameters (a,b,h;p,q,r) that one usually associates with such a group and hence with a simply-laced Coxeter-Dynkin diagram have a meaningful definition for the non-simply-laced diagrams, too, and as a byproduct we extend Saito's formula for the determinant of the Cartan matrix to all cases. Returning to invariant theory we show that for each irreducible representation i of a binary tetrahedral, octahedral, or icosahedral group one can find a homomorphism into a finite complex reflection group whose defining reflection representation restricts to i.

CFD and PIV investigation of UV reactor hydrodynamics
Creators: name: Sozzi, Angelo
Publisher: name: University of British Columbia
Year: 2009

description: The performance of ultraviolet (UV) reactors used for water treatment is greatly influenced by the reactor hydrodynamics, due to the non-homogeneity of the UVradiation field. Yet, a present lack of rigorous quantitative understanding of the flow behavior in such reactor geometries is shown to limit the versatile and efficient optimization of UV reactors. In this research, the key characteristics of turbulent flow in annular UV-reactors and its influence on reactor performance were studied using particle image velocimetry (PIV) measurements and computational fluid dynamics (CFD) simulations. Two conceptual reactor configurations, with inlets either concentric (L-shape) or normal (U-shape) to the reactor axis, were investigated experimentally. The time averaged velocity data revealed a strong dependency of the hydrodynamic profile to the inlet position. The frontal inlet of the L-shape reactor resulted in an expanding jet flow with high velocities close to the radiation source (UV-lamp) and areas of recirculation close to the inlet. The perpendicular inlet of the U-shape reactor brought about higher velocities along the outer reactor walls far from the central lamp. Numerical simulations, using a commercial CFD software package, Fluent, were performed for the L- and U-shape reactor configurations. The influences of mesh structure and the Standard n-e, Realizable K-e, and Reynolds stress (RSM) turbulence models were evaluated. The results from the Realizable «-e and RSM models were in good agreement with the experimental findings. However, the Realizable K-e model provided the closest match under the given computational restraints. UV disinfection models were developed by integrating UV-fluence rate and inactivation kinetics with the reactor hydrodynamics. Both, a particle tracking (Lagrangian) random walk model and a volumetric reaction rate based (Eulerian) model were implemented. The performance results of the two approaches were in good agreement with each other and with the experimental data from an industrial prototype reactor. The simulation results provided detailed information on the velocity profiles, reaction rates, and areas of possible short circuiting within the UV-reactor. It is expected that the application of the verified integrated CFD models will help to improve the design and optimization of UV-reactors.

description: We examine the temperature history of gas accreted by forming galaxies in SPH simulations. About half the gas shock heats to roughly the virial temperature of the galaxy potential well before cooling, condensing, and forming stars, but the other half radiates its acquired gravitational energy at much lower temperatures, typically T<10^5 K, and the histogram of maximum gas temperatures is clearly bimodal. The "cold mode" of gas accretion dominates for low mass galaxies (M_baryon < 10^{10.3}Msun or M_halo < 10^{11.4}Msun), while the conventional "hot mode" dominates the growth of high mass systems. Cold accretion is often directed along filaments, allowing galaxies to efficiently draw gas from large distances, while hot accretion is quasi-spherical. The galaxy and halo mass dependence leads to redshift and environment dependence of cold and hot accretion rates, with cold mode dominating at high redshift and in low density regions today, and hot mode dominating in group and cluster environments at low redshift. Star formation rates closely track accretion rates, and we discuss the physics behind the observed environment and redshift dependence of galactic scale star formation. If we allowed hot accretion to be suppressed by conduction or AGN feedback, then the simulation predictions would change in interesting ways, perhaps resolving conflicts with the colors of ellipticals and the cutoff of the galaxy luminosity function. The transition between cold and hot accretion at M_h ~ 10^{11.4}Msun is similar to that found by Birnboim & Dekel (2003) using 1-d simulations and analytic arguments. The corresponding baryonic mass is tantalizingly close to the scale at which Kauffmann et al. (2003) find a marked shift in galaxy properties. We speculate on connections between these theoretical and observational transitions.

Designed ligands for diagnosis and therapy

Publisher: name: University of British Columbia
Year: 2009

description: This thesis discusses three distinct medicinal inorganic chemistry projects involving the design of well-tailored ligands for diagnostic and therapeutic applications. In one study, combination agents for diabetes therapy were developed utilizing vanadium and the thiazolidinediones. A hybrid approach was used whereby the two aforementioned active agents were combined into one molecule. A series of bifunctional thiazolidinedione-containing pro-ligands were synthesized and complexed to vanadium. One vanadium complex, and associated ligand precursor, were found to be quite effective in lowering plasma glucose levels in an acute animal model of diabetes. In another study numerous tetrahydrosalen compounds were synthesized and evaluated for potential use in Alzheimer's disease chelation therapy. Glycosylated pro-drug forms were developed to minimize systemic metal chelation and potentially enhance brain uptake. Solution studies of two tetrahydrosalen ligands exhibiting remote glycosylation indicated that these compounds form neutral complexes with Cu2 + and Zn2 + at physiological pH (7.4). The final study investigated the chemistry of carbohydrate-appended metal (Re and 9 9 mTc) complexes for use as target-specific radiopharmaceuticals. A series of bidentate and tridentate carbohydrate-containing ligands were attached to the/ac-{M(CO)3}+(M = Re or 9 9 mTc) core and in all cases the carbohydrate moiety was determined to remain pendant. The bidentate analogs were found to be more susceptible towards ligand exchange than were the tridentate compounds. Clearly matching the tridentate binding capability of carbohydrate-appended ligands to the fac-{M(CO)3}+ core greatly stabilized the resulting complexes to ligand substitution processes in vitro.

description: We analyze the stability of dust layer in protoplanetary disk to understand the effect of the relative motion between gas and dust. The previous analyses not including the effect of relative motion between gas and dust show that the shear-induced turbulence may prevent the dust grains from settling sufficiently to be gravitationally unstable. We determine the growth rate of Kelvin-Helmholtz instability in wide range of parameter space, and propose a possible path toward the planetesimal formation through the gravitational instability. We expect the density of dust layer becomes $ρ_\mathrm{d}/ρ_\mathrm{g} \sim 200$ if the dust grains can grow up to 5m.

Observation of high-order Mollow triplet by quantum mode control with concatenated continuous driving

description: The Mollow triplet is a fundamental signature of quantum optics, and has been observed in numerous quantum systems. Although it arises in the 'strong driving' regime of the quantized field, where the atoms undergo coherent oscillations, it can be typically analyzed within the rotating wave approximation. Here we report the first observation of high-order effects in the Mollow triplet structure due to strong driving. In experiments, we explore the regime beyond the rotating wave approximation using concatenated continuous driving that has less stringent requirements on the driving field power. We are then able to reveal additional transition frequencies, shifts in energy levels, and corrections to the transition amplitudes. In particular, we find that these amplitudes are more sensitive to high-order effects than the frequency shifts, and that they still require an accurate determination in order to achieve high-fidelity quantum control. The experimental results are validated by the Floquet theory, which enables the precise numerical simulation of the evolution and further provides an analytical form for an effective Hamiltonian that approximately predicts the spin dynamics beyond the rotating wave approximation.

description: The current food crisis all over the globe has necessitated alternative policy actions by various stakeholders in almost all countries of the world. Consequently, efforts are focused on increased investment in agricultural research and development. The study evaluates impact of technological innovations on estimates of technical, allocative and cost efficiency from a parametric stochastic and non-parametric distance functions. Inefficiency effects are modelled in a second stage endogeniety-corrected Tobit regression model as a function of technological innovation and other policy variables. The results from both approaches show there is substantial technical, allocative and cost inefficiency in maize production and that analysis of technical, allocative and cost efficiency with respect to technological innovation and other policy factors are robust. Our results show that policies aimed at maize technology development and their timely dissemination, improvement in education, access to credit and extension among others could promote technical, allocative and cost efficiency, reduce yield variability, enhance farm income, food security and reduce poverty in Nigeria.

description: We give an exact spectral equivalence between the quantum group invariant XXZ chain with arbitrary left boundary term and the same XXZ chain with purely diagonal boundary terms. This equivalence, and a further one with a link pattern Hamiltonian, can be understood as arising from different representations of the one-boundary Temperley-Lieb algebra. For a system of size L these representations are all of dimension 2^L and, for generic points of the algebra, equivalent. However at exceptional points they can possess different indecomposable structures. We study the centralizer of the one-boundary Temperley-Lieb algebra in the 'non-diagonal' spin-1/2 representation and find its eigenvalues and eigenvectors. In the exceptional cases the centralizer becomes indecomposable. We show how to get a truncated space of 'good' states. The indecomposable part of the centralizer leads to degeneracies in the three mentioned Hamiltonians.

description: Communication protocols are the languages used by network nodes. Before a user equipment (UE) can exchange data with a base station (BS), it must first negotiate the conditions and parameters for that transmission. This negotiation is supported by signaling messages at all layers of the protocol stack. Each year, the mobile communications industry defines and standardizes these messages, which are designed by humans during lengthy technical (and often political) debates. Following this standardization effort, the development phase begins, wherein the industry interprets and implements the resulting standards. But is this massive development undertaking the only way to implement a given protocol? We address the question of whether radios can learn a pre-given target protocol as an intermediate step towards evolving their own. Furthermore, we train cellular radios to emerge a channel access policy that performs optimally under the constraints of the target protocol. We show that multi-agent reinforcement learning (MARL) and learning-to-communicate (L2C) techniques achieve this goal with gains over expert systems. Finally, we provide insight into the transferability of these results to scenarios never seen during training.

description: Increased droughts in southern Africa have noticed some appreciation of the role that partial wetland cultivation can play to address household food security. This has also witnessed some indication of possible relaxation of wetland cultivation restrictive policies in Zimbabwe. However, the general perceptions of society towards wetland cultivation remain unclear and critically important for policy crafting before blanket recommendations are made. Using a Binary Logistic Regression Model seven predictor independent variables were regressed against a binary dependent variable of wetland cultivation status of households with the implicit goal of estimating socio-economic factors capable of influencing households` participation in wetland cultivation. Results revealed that from the seven predictor variables, six variables had a significant influence, while one variable was not significant. The implied message centres on careful articulation of such a policy given the fact that, the dominant age group (young and educated household heads) had a negative attitude towards wetland cultivation, a crucial factor that may risk its rejection if put under a referendum. Intuitively results conjecture a bleak future for partial wetland cultivation as a possible land use because the expected future generation (current young and educated household heads) currently shares a negative attitude towards partial wetland cultivation.

Place points {x_i} in R^2 according to a Poisson process with intensity 1 and let G_A be the random graph with vertex set {x_i} and edges x_ix_j whenever x_i-x_j\in A. We show that if the area of A is large, then G_A almost surely has an infinite component. Moreover, if we fix ε, increase r and let n_c=n_c(ε) be the area of A when this infinite component appears, then n_c\to1 as ε\to 0. This is in contrast to the case of a ``square'' annulus where we show that n_c is bounded away from 1.

description: One of the main factors of a company's business performance is complete mobility and orientation of the employees towards realizing common interests and goals of the company as a whole. Activities aimed at that goal are also related to building a motivation system in the company. One of the means of motivation policy is the system of incentive rewards, where the information input is the calculation of costs and business results of a company, relying on complete tracking of business processes, according to functions, fields and centers of responsibility for achieved success or failure. Profit, as the final financial product of the company's activities, is basically the main activating force for all the employees. Their motivation helps successful achievement of a company's business policy and strategic development, through a functional system of measuring and evaluating results and adequate rewards.

description: An analogue of the geometrical optics for description of the modal structure of a wave field in a range-dependent waveguide is considered. In the scope of this approach the mode amplitude is expressed through solutions of the ray equations. This analytical description accounts for mode coupling and remains valid in a nonadiabatic environment. It has been used to investigate the applicability condition of the adiabatic approximation. An applicability criterion is formulated as a restriction on variations of the action variable of the ray.

description: This paper sought to investigate determinants of farmers’ compliance with coffee eco-certification standards in Mt. Kenya region. Socio-economic, institutional and farm factors were analyzed and the binary logistic regression model was used to predict factors enhancing compliance. The findings show that perception of benefits, coffee as the main source of income, annual coffee production, and the number of times a farmer sprayed annually; were the main drivers of compliance. The findings point towards a growing concern that certification projects focus on ‘progressive’ farmers rather than seek to uplift and integrate ‘weak’ farmers. This calls for concerted efforts among all key stakeholders to enhance inclusivity and participation.

description: We define modular Terwilliger algebras of association schemes, Terwilliger algebras over a positive characteristic field, and consider basic properties. We give a condition for the modular Terwilliger algebra to be non-semisimple. We show that the dimension of a Terwilliger algebra of a Johnson scheme depends on the characteristic of the coefficient field. We also give some other examples.

description: We study relevant deformations of an N=1 superconformal theory which is an exactly marginal deformation of U(N) N=4 SUSY Yang-Mills. The resulting theory has a classical Higgs branch that is a complex deformation of the orbifold C^3/Z_n x Z_n that is a non-compact Calabi-Yau space with isolated conifold singularities. At these singular points in moduli space the theory exhibits a duality cascade and flows to a confining theory with a mass gap. By exactly solving the corresponding holomorphic matrix model we compute the exact quantum superpotential generated at the end of the duality cascade and calculate precisely how quantum effects deform the classical moduli space by replacing the conifold singularities with three-cycles of finite size. Locally the structure is that of the deformed conifold, but the global geometry is different. This desingularized quantum deformed geometry is the moduli space of probe D3-branes at the end of a duality cascade realized on the worldvolume of (fractional) D3-branes placed at the isolated conifold singularities in the deformation of the orbifold C^3/Z_n x Z_n with discrete torsion.

description: We present an extensive study of the foreshock and aftershock signatures accompanying peaks of book sales. The time series of book sales are derived from the ranking system of Amazon.com. We present two independent ways of classifying peaks, one based on the acceleration pattern of sales and the other based on the exponent of the relaxation. They are found to be consistent and reveal the co-existence of two types of sales peaks: exogenous peaks occur abruptly and are followed by a power law relaxation, while endogenous sale peaks occur after a progressively accelerating power law growth followed by an approximately symmetrical power law relaxation which is slower than for exogenous peaks. We develop a simple epidemic model of buyers connected within a network of acquaintances which propagates rumors and opinions on books. The comparison between the predictions of the model and the empirical data confirms the validity of the model and suggests in addition that social networks have evolved to converge very close to criticality (here in the sense of critical branching processes of opinion spreading). We test in details the evidence for a power law distribution of book sales and confirm a previous indirect study suggesting that the fraction of books (density distribution) $P(S)$ of sales S is a power law P(S) ~ 1/S^{1+mu} with mu close to 2.

description: This paper describes important regulation issues that concern microfinance. It starts by considering literature on how and why to regulate and supervise microfinance. Considering the specific case of microfinance in Albania, it analyzes the context of this industry and some particular issues that might influence its growth. Related regulation in Albania seems to be not activity–oriented since a real definition of microfinance is lacking in the Albanian law. Therefore, Albanian microfinance sector needs, first of all, a microcredit and microfinance definition to implement the right development policies and avoid confusion and license misuse. Moreover, the regulatory framework seems to be too restrictive for institutions supposed to be engaged in microfinance example high capital requirement and provisioning. Possible interventions can be in lowering minimum capital requirements for NBFIs to improve entrance, simplifying procedures, documentation and harmonization of the taxation treatment of institutions to enhance development, encourage access and avoid market distortions. There is the need to implement regulation considering microfinance as an activity, and develop a regulatory framework to induce commercial banks integrate downward into the microfinance market and help informal start-ups institutions develop and get formalized.
Who are the Real Gainers of Trade Liberalization in Kenya's Maize Sector?

description: In Kenya, trade policy reforms in the cereals sector were initiated as a key component of the economy-wide structural adjustment programmes (SAPs) during the mid 1980s. The SAPs were later strengthened and made irreversible by Kenya’s commitments at the multilateral trade negotiations. However, the welfare effects of these trade policy reforms remain controversial. This paper to quantifies the market and welfare impacts of trade liberalization in Kenya’s maize sector using a partial equilibrium model with market interrelationships at the farm, wholesale and retail levels. The model is calibrated to simulate a 24 percent reduction in maize import tariffs and a complete abolition of tariffs. The simulations results suggest that tariff reductions yield price decreases across the three market levels. The declining prices increase maize consumption but reduce domestic production. Consequently, consumer surplus increases while producer surplus decreases. However, the gain in consumer surplus is not sufficient to compensate the loss in producer surplus. Thus, the implementation of the multilateral agricultural trade agreement is likely to leave Kenya’s maize sector worse off and cannot be considered as a viable policy based on the compensation principle.

description: Transverse hadron spectra from proton-proton, proton-nucleus and nucleus-nucleus collisions from 2 AGeV to 21.3 ATeV are investigated within two independent transport approaches (HSD and UrQMD). For central Au+Au (Pb+Pb) collisions at energies above $E_{\rm lab}\sim$ 5 AGeV, the measured $K^{\pm}$ transverse mass spectra have a larger inverse slope parameter than expected from the default calculations. The additional pressure - as suggested by lattice QCD calculations at finite quark chemical potential $μ_q$ and temperature $T$ - might be generated by strong interactions in the early pre-hadronic/partonic phase of central Au+Au (Pb+Pb) collisions. This is supported by a non-monotonic energy dependence of $v_2/< p_T>$ in the present transport model.

description: We use Chiral Perturbation Theory to compute the nucleon mass-shift due to finite volume and temperature effects. Our results are valid up to next-to-leading order in the "\eps-regime" (mL ~ mβ<< 1) as well as in the "p-regime" (mL ~ mβ>> 1). Based on the two leading orders, we discuss the convergence of the expansion as a function of the lattice size and quark masses. This result can be used to extrapolate lattice results obtained from lattice sizes smaller than the pion cloud, avoiding the numerical simulation of physics under theoretical control. An extraction of the low-energy coefficient c_3 of the chiral Lagrangean from lattice simulations at small volumes and a ``magic'' ratio β=1.22262 L might be possible.
