description: Recent efforts to forge a consensus on the role developing countries should play in reducing global greenhouse gas emissions have focused attention on climate friendly technologies (CFTs), most notably those that enhance energy efficiency. In the medium term, the effectiveness of technology-based climate strategies will depend critically on the rates at which CFTs diffuse in developing countries. This paper reviews some of the key findings of the economics research on technology diffusion and assesses the implications for climate policy. The most obvious lessons from this research are that widespread diffusion of CFTs may take decades, and that diffusion rates in developing and industrialized countries are likely to be quite different. In addition, the literature has implications for a number of strategies for promoting technology diffusion including information dissemination, factor price rationalization, and investment in human capital.

Publisher: name: University of British Columbia
Year: 2009

description: This study focuses on the nature of the school advisor's roles within a collaborative educational setting, specifically, a partnership involving a school district, university and teachers association referred to as the Richmond Teacher Education Project. The study investigates how school advisors view their roles and responsibilities within a cohort group. School advisors describe their experiences according to role, motivations, preparation and training, improvements to the program and professional/ethical considerations. Findings from the study indicate that the role development of school advisors is dependent on the amount of time spent as a member of the Richmond Practicum Project and on the relationship-building process between the student teachers and other members of the cohort grouping. All subjects mention some difficulty in their role as the primary evaluator and believed that the faculty advisor should share this role.

description: This paper presents a research-informed teaching (RIT) and learning approach that fosters interdisciplinary collaboration and hands-on experimentation for a dynamic advancement of academic research in the field of sustainable architecture. Additionally, transdisciplinary collaborations with various research partners and funding bodies within academic education underline the relevance of the teaching results and the importance of building and testing the developed concepts at architectural scale. This paper presents the example of interdisciplinary teaching courses that are part of a strategy for rapid innovation at the intersection of research and teaching at the Professorship for Digital Design and Fabrication (DDF) at the Karlsruhe Institute of Technology (KIT). They enable students to gain transformative knowledge in interdisciplinary teamwork focused on the intertwined topics of architecture, digital construction technology and sustainability. Here presented is one case study of the resulting student work, which addresses challenges in the construction sector through the exploration of low-emissions processing for circular materials such as willow, highlighting its rapid regrowth and adaptability of digital fabrication processes. The knowledge gained through these research-informed teaching methods is applied through the production of experimental prototypes that are used to visualize construction innovation for public discussion.

description: Direct Feedback Alignment (DFA) is emerging as an efficient and biologically plausible alternative to the ubiquitous backpropagation algorithm for training deep neural networks. Despite relying on random feedback weights for the backward pass, DFA successfully trains state-of-the-art models such as Transformers. On the other hand, it notoriously fails to train convolutional networks. An understanding of the inner workings of DFA to explain these diverging results remains elusive. Here, we propose a theory for the success of DFA. We first show that learning in shallow networks proceeds in two steps: an alignment phase, where the model adapts its weights to align the approximate gradient with the true gradient of the loss function, is followed by a memorisation phase, where the model focuses on fitting the data. This two-step process has a degeneracy breaking effect: out of all the low-loss solutions in the landscape, a network trained with DFA naturally converges to the solution which maximises gradient alignment. We also identify a key quantity underlying alignment in deep linear networks: the conditioning of the alignment matrices. The latter enables a detailed understanding of the impact of data structure on alignment, and suggests a simple explanation for the well-known failure of DFA to train convolutional neural networks. Numerical experiments on MNIST and CIFAR10 clearly demonstrate degeneracy breaking in deep non-linear networks and show that the align-then-memorise process occurs sequentially from the bottom layers of the network to the top.

These sources were jointly selected from Spitzer and Chandra imaging surveys in the NDWFS Bootes field and were selected from their bright X-ray fluxes to host luminous AGN. None of the spectra show significant emission from polycyclic aromatic hydrocarbons (PAHs; 6.2um equivalent widths <0.2um), consistent with their infrared emission being dominated by AGN. Nine of the X-ray sources show 9.7um silicate absorption features. Their redshifts are in the range 0.9

description: It is known that the small-world structure constitutes sufficient conditions to sustain cooperation and thus enhances cooperation. On the contrary, the network with a very long average distance is usually thought of as suppressing the emergence of the cooperation. In this paper we show that the fractal structure, of which the average distance is very long, does not always play a negative role in the organization of cooperation. Compared to regular networks, the fractal structure might even facilitate the emergence of cooperation. This mainly depends on the existence of locally compact clusters. The sparse inter-connection between these clusters constructs an asymmetric barrier that the defection strategy is almost impossible to cross, but the cooperation strategy has a not too small chance. More generally, the network need not to be a standard fractal, as long as such structures exist. In turn, when this typical structure is absent, the fractal structure will also suppress the emergence of the cooperation, such as the fractal configuration obtained by diluting a random tree-like network. Our findings also clarify some contradictions in the previous studies, and suggest that both removing and inserting links from/into a regular network can enhance cooperation.

description: In southern Africa, HIV/AIDS is considered to be a critical factor conditioning rural economic development , exacerbating already difficult problems with climatic variability and poverty. In their efforts to use household surveys to obtain information on rural adult mortality and morbidity and their effects on rural household livelihoods, Michigan State University researchers and their local collaborators in the Ministries of Agriculture of Rwanda (MINAGRI) and Mozambique (MADER), have learned various lessons. Using household surveys to estimate the impact on the households requires careful attention to detail as well as skilled use of econometric tools. The difficult modeling issues involved in such estimation is not be discussed in this paper. Rather, we focus on the basic data collection required and the formulation of effective survey questions. Based on the survey instruments used in these two countries, suggestions are made to improve the ability of researchers to estimate mortality rates, evaluate changes in demographic composition of the households, and elicit information from households regarding incidence of illness and death, their effects on household livelihoods, and the households' response strategies. This paper provides recommendations for future survey instruments to improve the knowledge base so critical for the design of interventions.

description: We establish a duality between the quantum wave vector spectrum and the eigenmodes of the classical Liouvillian dynamics for integrable billiards. Signatures of the classical eigenmodes appear as peaks in the correlation function of the quantum wave vector spectrum. A semiclassical derivation and numerical calculations are presented in support of the results. These classical eigenmodes can be observed in physical experiments through the auto-correlation of the transmission coefficient of waves in quantum billiards. Exact classical trace formulas of the resolvent are derived for the rectangle, equilateral triangle, and circle billiards. We also establish a correspondence between the classical periodic orbit length spectrum and the quantum spectrum for integrable polygonal billiards.

description: This paper proposes an asychronous distributed leader-follower control method to achieve conservation voltage reduction (CVR) in three-phase unbalanced distribution systems by optimally scheduling smart inverters of distributed energy resources (DERs). One feature of the proposed method is to consider integrated primary-secondary distribution networks and voltage dependent loads. To ease the computational complexity introduced by the large number of secondary networks, we partition a system into distributed leader-follower control zones based on the network connectivity. To address the non-convexity from the nonlinear power flow and load models, a feedback-based linear approximation using instantaneous power and voltage measurements is proposed. This enables the online implementation of the proposed method to achieve fast tracking of system variations led by DERs. Another feature of the proposed method is the asynchronous implementations of the leader-follower controllers, which makes it compatible with non-uniform update rates and robust against communication delays and failures. Numerical tests are performed on a real distribution feeder in Midwest U. S. to validate the effectiveness and robustness of the proposed method.

description: The alarmingly high mortality rate and increasing global prevalence of cardiovascular diseases signify the crucial need for early detection schemes. Phonocardiogram (PCG) signals have been historically applied in this domain owing to its simplicity and cost-effectiveness. In this paper, we propose CardioXNet, a novel lightweight end-to-end CRNN architecture for automatic detection of five classes of cardiac auscultation namely normal, aortic stenosis, mitral stenosis, mitral regurgitation and mitral valve prolapse using raw PCG signal. The process has been automated by the involvement of two learning phases. Three parallel CNN pathways have been implemented in the representation learning phase to learn the coarse and fine-grained features from the PCG and to explore the salient features from variable receptive fields involving 2D-CNN based squeeze-expansion. Thus, in the representation learning phase, the network extracts efficient time-invariant features and converges with great rapidity. In the sequential residual learning phase, with the bidirectional-LSTMs and the skip connection, the network can proficiently extract temporal features without performing any feature extraction on the signal. The obtained results demonstrate that the proposed end-to-end architecture yields outstanding performance in all the evaluation metrics compared to the previous state-of-the-art methods with up to 99.60% accuracy, 99.56% precision, 99.52% recall and 99.68% F1- score on an average while being computationally comparable. This model outperforms the previous works using the same dataset by a considerable margin. The high accuracy metrics on both primary and secondary dataset combined with a significantly low number of parameters and end-to-end prediction approach makes the proposed network suitable for point of care CVD screening in low resource setups using memory constraint mobile devices.

Interim Report on Rural Secondary, Base Stabilization Projects

Subjects: subject: Transportation Engineering

description: Early in 1962, the Division of Rural Highways selected several base stabilization projects for construction during the 1962 season. These projects were to involve the addition of 1-1/2 to 3 inches of compacted granular base to existing, rural secondary, traffic-bound macadam roads. Since these roads were not intended to be surfaced, calcium chloride and sodium chloride were to be added to the additional granular base material in an attempt to retain or "hold" the aggregate on the road. This treatment was in tended to improve the road and to build up the base over a period of a few years until the road could be surfaced.  The Division of Research was requested to observe the construction and performance of these projects and to evaluate the effectiveness of calcium or sodium chloride in this type of "stage" construction. Accordingly, eight projects totaling 40.111 miles were selected for observation. These projects included three (12.434 miles) in which calcium chloride was used, three (11.200 miles) in which sodium chloride was used, and two (16.477 miles) in which no additive was used. Two additional projects involving similar types of construction are also reported. The Garrard County project was completed however, much of this base material is scattered or washed into the ditches or is pulverized and blown away. This results in an inadequate base when the wearing course is eventually constructed.

description: Clinical machine learning is increasingly multimodal, collected in both structured tabular formats and unstructured forms such as freetext. We propose a novel task of exploring fairness on a multimodal clinical dataset, adopting equalized odds for the downstream medical prediction tasks. To this end, we investigate a modality-agnostic fairness algorithm - equalized odds post processing - and compare it to a text-specific fairness algorithm: debiased clinical word embeddings. Despite the fact that debiased word embeddings do not explicitly address equalized odds of protected groups, we show that a text-specific approach to fairness may simultaneously achieve a good balance of performance and classical notions of fairness. We hope that our paper inspires future contributions at the critical intersection of clinical NLP and fairness.

description: Virtually all technology adoption studies are conducted ex post, yet policy makers often need to assess the likely level of adoption before the technology is introduced. This study uses data from a contingent valuation survey of Michigan corn growers to assess what factors would influence the adoption of two safer corn herbicides, one that is not carcinogenic and one that does not leach. Results indicate that price, risk perception, and sources of pest control information are all important. This suggests that public policies designed to change perceptions and improve information dissemination may encourage voluntary use of more environmentally friendly technologies.

description: The local composite operator A^2 is added to the Zwanziger action, which implements the restriction to the Gribov region in Euclidean Yang-Mills theories in the Landau gauge. We prove the renormalizability of this action to all orders of perturbation theory. This allows to study the dimension two gluon condensate by the local composite operator formalism when the restriction is taken into account. The effective action is evaluated at one-loop order in the MSbar scheme. We obtain explicit values for the Gribov parameter and for the mass parameter due to , but the expansion parameter turns out to be rather large. Furthermore, an optimization of the perturbative expansion in order to reduce the dependence on the renormalization scheme is performed. The properties of the vacuum energy, with or without , are investigated. It is shown that in the original Gribov-Zwanziger formulation (without ), the vacuum energy is always positive at 1-loop order, independently from the renormalization scheme and scale. With , we are unable to come to a definite conclusion at the order considered. In the MSbar scheme, we still find a positive vacuum energy, again with a relatively large expansion parameter, but there are renormalization schemes in which the vacuum energy is negative, albeit the dependence on the scheme itself appears to be strong. We recover the well known consequences of the restriction, and this in the presence of : an infrared suppression of the gluon propagator and an enhancement of the ghost propagator. This behaviour is in qualitative agreement with the results obtained from the studies of the Schwinger-Dyson equations and from lattice simulations.

description: Emerging economies such as South Africa, only a few years out of apartheid, have been feeling the strains of socio-political change. While South Africa has experienced political reform, economic reform and access are slow to come. Currently, South Africa is the 7th largest producer of wine in the world. Although this industry is impressive, the apartheid era production practices have caused primarily the European consumers and media to be vocal about this issue. However, this concern has spread to other regions. The South African government and wine industry must respond to the external and internal market pressures and minimize transaction costs. Both entities want to increase wine exports and expand market share, however, given the socio-economic and political climate in the country neither knows how to manage this difficult process which emanates from deeply rooted distrust of groups within the country. Socio-political constraints facing previously disadvantaged groups (PDG) as emerging business owners need to be understood; and, measures which could be undertaken by government and industry need to be identified. The objectives of this research were to identify: institutional constraints and transaction costs faced by PDGs aspiring toward production and leadership roles in the wine industry; ways the government can collaborate with the KWV to build social capital and promote PDG ownership in the wine industry, thus minimizing social conflict; and, identify industry strategies to increase exports and international market share under the "New South Africa" banner. This analysis was based on primary and secondary data and information gathered on site. Several potential solutions were suggested for ways to include PDGs in the South African wine market while minimizing the impact on the market shares of existing producers. It is anticipated that the window of opportunity to increase exports and involve PDG is quite small.

description: Poor child health and nutrition persist throughout West Africa. This research analyzes the impact of key economic variables, including income, education and background characteristics, on child health and nutrition across nine different countries. The results are interpreted in the context of differing levels of economic development among these nations. The findings do not show wealth and parental education to be robust across the sample, but maternal background characteristics have a positive, statistically significant and highly consistent effect across all the countries. The importance of mothers' height does not simply represent a genetic influence, but can be interpreted to signify that women who have had a healthier upbringing and hence are taller, have healthier children, ceteris paribus. This finding is consistent with long-run observations that increases in health (and height) coincide with economic development.

description: We computationally demonstrate a new method for coherently controlling the rotation-axis direction in asymmetric top molecules with an optical centrifuge. Appropriately chosen electric-field strengths and the centrifuge's acceleration rate allow to generate a nearly arbitrary rotational wavepacket. For D$_2$S and 2H-imidazole (C$_3$H$_4$N$_2$) we created wavepackets at large values of the rotational quantum number $J$ with the desired projections of the total angular momentum onto two of the molecules' principal axes of inertia. One application of the new method is three-dimensional alignment with a molecular axis aligned along the laser's wave vector, which is important for the three-dimensional imaging of molecules yet not accessible in standard approaches. The simultaneous orientation of the angular momentum in the laboratory frame and in the molecular frame could also be used in robust control of scattering experiments.

The ratio of correlation to delayed response in the stochastic model introduced in [Phys. Rev. Lett. 93, 240601 (2004)] is shown to depend on measurement time. The fluctuation temperature defined by this ratio differs both from the temperature of the environment performing the driving, and from other effective temperatures of the system, such as the average energy (or "granular temperature"). General explanations are given for the time independence of fluctuation temperature for simple measurements or long measurement times.

description: During the 1960's and 1970's, the extent of agricultural protection increased rapidly not only in Japan but also in South Korea and Taiwan. By the early 1980's food prices in East Asia averaged two or three times international levels, rivalling those in Western Europe. A multi-commodity stochastic simulation model measures the extent to which policies in East Asia have reduced the mean and increased the variance of international prices for grain and meat, reduced world trade in these products and affected economic welfare in East Asia and elsewhere. The effects of continued growth in East Asia's protection through the 1980's (leading to rice export surpluses) are then compared with the effects of partial liberalization.

Bump Cepheids in the Magellanic Clouds: Metallicities, the Distances to the LMC and SMC, and the Pulsation-Evolution Mass Discrepancy

description: We utilize nonlinear pulsation models to reproduce the observed light and color curves for two samples of bump Cepheid variables, 19 from the Large Magellanic Cloud and 9 from the Small Magellanic Cloud. This analysis determines the fundamental parameters mass, luminosity, effective temperature, metallicity, distance and reddening for the sample of stars. The use of light curve shape alone to determine metallicity is a new modelling technique introduced here. The metallicity, distance and reddening distributions for the two samples are in agreement with those of similar stellar populations in the literature. The distance modulus of the Large Magellanic Cloud is determined to be 18.54$\pm$0.018 and the distance modulus of the Small Magellanic Cloud is determined to be 18.93$\pm$0.024. The mean Cepheid metallicities are $Z = 0.0091\pm0.0007$ and $0.0050\pm0.0005$ for the LMC and SMC, respectively. The masses derived from pulsation analysis are significantly less than those predicted by stellar evolutionary models with no or mild convective core overshoot. We show that this discrepancy can not be accounted for by uncertainties in our input opacities or in mass-loss physics. We interpret the observed mass discrepancy in terms of enhanced internal mixing in the vicinity of the convective core during the main-sequence lifetime and find that the overshoot parameter $Λ_{c}$ rises from 0.688$\pm$0.009H_p at the mean LMC metallicity to 0.746$\pm$0.009H_p in the SMC.

Search for the rare decay of the W boson into a pion and a photon in proton-proton collisions at $\sqrt{s} = $ 13 TeV

description: A search is performed for the rare decay W$^\pm\toπ^\pmγ$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV. Data corresponding to an on W integrated luminosity of 137 fb$^{-1}$ were collected during 2016 to 2018 with the CMS detector. This analysis exploits a novel search strategy based on W boson production in top quark pair events. An inclusive search for the W$^\pm\toπ^\pmγ$ decay is not optimal at the LHC because of the high trigger thresholds. Instead, a trigger selection is exploited in which the W boson originating from one of the top quarks is used to tag the event in a leptonic decay. The W boson emerging from the other top quark is used to search for the W$^\pm\toπ^\pmγ$ signature. Such decays are characterized by an isolated track pointing to a large energy deposit, and by an isolated photon of large transverse momentum. The presence of b quark jets reduces the background from the hadronization of light-flavor quarks and gluons. The W$^\pm\toπ^\pmγ$ decay is not observed. An upper exclusion limit is set to this branching fraction, corresponding to 1.50 $\times$ 10$^{-5}$ at 95% confidence level, whereas the expected upper limit exclusion limit is 0.85 $^{+0.52}_{-0.29}$ $\times$ 10$^{-5}$.

Compositional disorder and its influence on the structural, electronic and magnetic properties of MgC(Ni_{1-x}Co_{x})_{3} alloys using first-principles

description: First-principles, density-functional based electronic structure calculations are carried out for MgC(Ni_{1-x}Co_{x})_{3} alloys over the concentration range 0\leq x\leq1, using Korringa-Kohn-Rostoker coherent-potential approximation (KKR CPA) method in the atomic sphere approximation (ASA). The self-consistent calculations are used to study the changes as a function of x in the equation of state parameters, total and partial densities of states, magnetic moment and the on-site exchange interaction parameter. To study the magnetic properties as well as its volume dependence, fixed-spin moment calculations in conjunction with the phenomenological Landau theory are employed. The salient features that emerge from these calculations are (i) a concentration independent variation in the lattice parameter and bulk modulus at x~0.75 with an anomaly in the variation of the pressure derivative of bulk modulus, (ii) the fixed-spin moment based corrections to the overestimated magnetic ground state for 0.0\leq x\leq0.3 alloys, making the results consistent with the experiments, and (iii) the possibility of multiple magnetic states at x~0.75, which, however, requires further improvements in the calculations.

description: We construct the one-dimensional topological sector of $\mathcal N = 6$ ABJ(M) theory and study its relation with the mass-deformed partition function on $S^3$. Supersymmetric localization provides an exact representation of this partition function as a matrix integral, which interpolates between weak and strong coupling regimes. It has been proposed that correlation functions of dimension-one topological operators should be computed through suitable derivatives with respect to the masses, but a precise proof is still lacking. We present non-trivial evidence for this relation by computing the two-point function at twoloop, successfully matching the matrix model expansion at weak coupling and finite ranks. As a by-product we obtain the two-loop explicit expression for the central charge $c_T$ of ABJ(M) theory. Three- and four-point functions up to one-loop confirm the relation as well. Our result points towards the possibility to localize the one-dimensional topological sector of ABJ(M) and may also be useful in the bootstrap program for 3d SCFTs.

The Josephson relation for the superfluid density in the BCS-BEC crossover

description: The Josephson relation for the superfluid density is derived for a Fermi superfluid in the BCS-BEC crossover. This identity extends the original Josephson relation for Bose superfluids. It gives a simple exact relation between the superfluid density $ρ_s$ and the broken-symmetry Cooper pair order parameter $Δ_0$ in terms of the infrared limit of the pair fluctuation propagator. The same expression holds through the entire BCS-BEC crossover, describing the superfluid density of a weak-coupling BCS superfluid as well as the superfluid density of a Bose condensate of dimer molecules.

A Note on Cost Functions and the Regression Fallacy

Year: 1983

description: Random variation in output may lead to serious bias in cost function estimates. Despite the availability of simple, consistent instrumental variable estimators to deal with this problem, most empirical studies appear to have ignored this errors-in-variables problem, or dealt with it in an ad hoc manner. In this note, an instrumental variable approach is suggested, and applied to the estimation of cost-output relationships for a sample of irrigated citrus farms. Ordinary least squares was found to result in a statistically significant bias. Although this bias did not alter the economic interpretation of the results for the sample used, the bias is likely to be more serious for samples with greater chance variation in output. Thus, it is argued that all cost function studies should explicitly deal with this problem.
