description: Runtime nondeterminism is a fact of life in modern database applications. Previous research has shown that nondeterminism can cause applications to intermittently crash, become unresponsive, or experience data corruption. We propose Adaptive Interventional Debugging (AID) for debugging such intermittent failures. AID combines existing statistical debugging, causal analysis, fault injection, and group testing techniques in a novel way to (1) pinpoint the root cause of an application's intermittent failure and (2) generate an explanation of how the root cause triggers the failure. AID works by first identifying a set of runtime behaviors (called predicates) that are strongly correlated to the failure. It then utilizes temporal properties of the predicates to (over)-approximate their causal relationships. Finally, it uses fault injection to execute a sequence of interventions on the predicates and discover their true causal relationships. This enables AID to identify the true root cause and its causal relationship to the failure. We theoretically analyze how fast AID can converge to the identification. We evaluate AID with six real-world applications that intermittently fail under specific inputs. In each case, AID was able to identify the root cause and explain how the root cause triggered the failure, much faster than group testing and more precisely than statistical debugging. We also evaluate AID with many synthetically generated applications with known root causes and confirm that the benefits also hold for them.

description: We consider modelling time series using a generalized additive model with firstorder Markov structure and mixed transition density having a discrete component at zero and a continuous component with positive sample space. Such models have application, for example, in modelling daily occurrence and intensity of rainfall, and in modelling the number and size of insurance claims. We show how these methods extend the usual sinusoidal seasonal assumption in standard chain-dependent models by assuming a general smooth pattern of occurrence and intensity over time. These models can be fitted using standard statistical software. The methods of Grunwald and Jones (1998) can be used to combine these separate occurrence and intensity models into a single model for amount. We use 36 years of rainfall data from Melbourne, Australia, as a vehicle of illustration, and use the models to investigate the effect of the El Nino phenomenon on Melbourne's rainfall.

description: This research is focused on the development of a new methodology to curate political performance art from the Baltic countries and Sápmi. Sámi and Baltic artists share a colonial history connected to their traditional lands, which is often why they work with such politically loaded themes. A more complete understanding of their artworks by audiences can contribute to opening up a social dialogue about these issues, which could have the effect of lessening the notion of Other and erasing the hierarchies of cultural centre and periphery. Performance and live artwork can generally be experienced by the audience only once. Thus, the audience has only one chance to grasp the artwork and understand it. Here, the curator’s task is to establish a close dialogue with the artist and shape the meeting point with the audience in order to lower the barriers between the artist (and their artwork’s content) and the audience.\r\nHow can curators work with live art and performances by Baltic and Sámi artists themed around postcolonial memory and decolonisation to give international audiences a more coherent understanding of such artwork? The results of my research, key points towards a new curatorial methodology, are useful for the education of curators. The methodology developed could be used by art institutions such as art centres and galleries that work with performance art and present artwork from the Baltic region and indigenous Sámi artists, which often deals with the themes of decolonisation and postcolonial memory. Lastly, the methodology could increase engagement and connectedness with audiences to the performance artwork they experience.

description: This work proposes a novel multi-output neural network for the prediction of the lift coefficient of aerofoils using inviscid compressible flow data. Contrary to existing neural networks that are designed to predict aerodynamic quantities of interest, the proposed network considers as output the pressure at a number of selected points on the aerofoil surface. The proposed approach is compared against the more traditional network where the lift coefficient is directly the only output of the network. Furthermore, a detailed comparison of the proposed neural network against the popular proper orthogonal decomposition method is presented. The numerical results, involving high dimensional problems with flow and geometric parameters, show the benefits of the proposed approach.

description: The ongoing development of intense high-harmonic generation (HHG) sources has recently enabled highly nonlinear ionization of atoms by the absorption of at least 10 extreme-ultraviolet (XUV) photons within a single atom [Senfftleben \textit{et al.}, arXiv1911.01375]. Here we investigate the role that reshaping of the fundamental, few-cycle, near-infrared (NIR) driving laser within the 30-cm-long HHG Xe medium plays in the generation of the intense HHG pulses. Using an incident NIR intensity that is higher than what is required for phase-matched HHG, signatures of reshaping are found by measuring the NIR blueshift and the fluorescence from the HHG medium along the propagation axis. These results are well reproduced by numerical calculations that show temporal compression of the NIR pulses in the HHG medium. The simulations predict that after refocusing an XUV beam waist radius of 320 nm and a clean attosecond pulse train can be obtained in the focal plane, with an estimated XUV peak intensity of 9x10^15 W/cm^2. Our results show that XUV intensities that were previously only available at large-scale facilities can now be obtained using moderately powerful table-top light sources.

description: Many studies have investigated the issue of time stationarity of an asset's systematic risk. While there is considerable evidence to suggest that an asset's systematic risk is best described by some stochastic parameter model, little work has been conducted in determining the most appropriate stochastic parameter model. This paper addresses this issue. We extend the study conducted by Fail', Lee and Fry (1992) to investigate which varying coefficient model best describes the systematic risk of assets in the Australian equity market, for those assets for which a constant coefficient model is found to be inadequate. Our testing stategy is point optimal (see King (1987a)) given that this approach to testing is designed to have good small sample properties. Our results suggest that generally in cases where a stochastic parameter is appropriate a Hildreth-Houck (1968) random coefficient model is the preferred model.

title: Driving Institutional Innovation for Agricultural Innovation Through R&D Projects: Learning From Two Experiences of Multi-Stakeholder Platforms Formation and Operation in Bolivia
Creators: name: Velasco MacLean, Claudio
Publisher: name: The Open University
Year: 2013

description: The idea that agricultural innovation does not only result from the transfer of research outputs to farmers but involves heterogeneous individuals and organizations interacting with each other and organizational and institutional conditions that constitute incentives or impediments for innovation to take place, is increasingly recognized as a promising idea among researchers and development practitioners engaged in research and development projects in developing countries. However the challenge of how to make these ideas accessible to practitioners and researchers with action-oriented purposes, whether for the design and implementation of R&D projects or for the in-depth investigation of innovation processes, has not yet been sufficiently addressed. This is precisely the focus of this research. It seeks to begin filling this gap with theoretical, empirical and methodological contributions by studying in-depth two cases of R&D project-driven attempts to foster the establishment and operation of multi-stakeholder platforms within the Bolivian context of agricultural innovation. Combining conceptual developments offered by the innovation systems and collective action approaches, this research explores the formation and operation of two multi-stakeholder, R&D project-driven processes of collective institutional innovation. Using action-oriented research methods, it was found that how, and with what effects, R&D projects act as drivers of institutional innovations processes is influenced by the tradition of designing and managing R&D projects, as well as by the prescriptive nature of projects defining what should be done, by whom, how, with what results, and for the benefit of whom. There are implications for the design and management of R&D projects when they are used as institutional innovation drivers. The implications relate to the definition of objectives, outcomes and indicators of achievement; the definition of roles and positions of the players; and to the instruments for projects planning, monitoring and evaluation. These research findings can help to shape agricultural innovation in Bolivia.
Exploring the impact of somatic variant burden on seizures in focal cortical dysplasia

Year: 2024

description: Somatic variants, or variants acquired post-zygotically, accumulate in all individuals over the course of their lifespan and can lead to a wide range of neurological disorders. Somatic variants arising during embryonic brain development are significant contributors to the genetic risk of epilepsy-associated focal malformations of cortical development and focal epilepsy without radiographic lesions. The propensity for any individual somatic variant to cause disease depends on its impact on the protein, as well as on the variant burden, which is the proportion of cells that carry the variant. The variant burden depends on the timing of the mutational event and on whether cells continue to divide after its occurrence.

BACKGROUND: Despite a higher risk of classical Hodgkin lymphoma (cHL) in people with HIV and the demonstrated safety and efficacy of PD-1 blockade in cHL, there are limited data on the use of these agents in HIV-associated cHL (HIV-cHL). PATIENTS/METHODS: We retrospectively identified patients with HIV-cHL from the "Cancer Therapy using Checkpoint inhibitors in People with HIV-International (CATCH-IT)" database who received nivolumab or pembrolizumab, alone or in combination with other agents, and reviewed records for demographics, disease characteristics, immune-mediated adverse events (imAEs), and treatment outcomes. Changes in CD4+ T-cell counts with treatment were measured via Wilcoxon signed-rank tests. Overall response rate (ORR) was defined as the proportion of patients with partial or complete response (PR/CR) per 2014 Lugano classification. RESULTS: We identified 23 patients with HIV-cHL who received a median of 6 cycles of PD-1 blockade: 1 as 1st-line, 6 as 2nd-line, and 16 as ≥3rd-line therapy. Seventeen (74%) patients received monotherapy, 5 (22%) received nivolumab plus brentuximab vedotin, and 1 received nivolumab plus ifosfamide, carboplatin, and etoposide. The median baseline CD4+ T-cell count was 155 cells/µL, which increased to 310 cells/µL at end-of-treatment (P = .009). Three patients had grade 3 imAEs; none required treatment discontinuation. The ORR was 83% with median duration of response of 19.7 months. The median progression-free survival was 21.2 months and did not differ between patients with <200 versus ≥200 CD4+ cells/µL (P = .95). CONCLUSION: Our findings support the use of PD-1 blockade in HIV-cHL for the same indications as the general population with cHL.

description: In the present paper, the saddle point approximations to the density and tail probability of a ratio of quadratic forms in normal variables are derived. A numerical exposition via the Durbin-Watson test statistic reveals several desirable features. Beyond their accuracy and robustness to extreme scenarios, the approximations, which only involve a limited number of computable functions, provide the practitioner with an accessible and a very powerful tool.

description: The eccentricity (anti-adjacency) matrix $\varepsilon(G)$ of a graph $G$ is obtained from the distance matrix by retaining the eccentricities in each row and each column. The $\varepsilon$-eigenvalues of a graph $G$ are those of its eccentricity matrix $\varepsilon(G),$ and the eccentricity energy (or the $\varepsilon$-energy) of $G$ is the sum of the absolute values of $\varepsilon$-eigenvalues. In this paper, we establish some bounds for the $\varepsilon$-energy of the complete multipartite graph $K_{n_1, n_2, \ldots,n_p}$ of order $n= \sum_{i=1}^p n_i $ and characterize the extreme graphs. This partially answers the problem given in Wang {\em et al.} (2019). We finish the paper showing graphs that are not $\varepsilon$-cospectral with the same $\varepsilon$-energy.

description: A mean shift can cause tests for a unit root to erroneously fail to reject the null hypothesis of the existence of a unit root. Perron (1990) and Hendry and Neale (1991) provide simulation evidence of this for (augmented) Dickey-Fuller tests in models without a time trend. This paper extends these analyses by considering a wider range of test statistics (including statistics proposed by Bhargava (1986)) applied to models (possibly including a time trend) subject to a shift in mean. Our simulation results show that, at least for alternatives close to the unit root, either an appropriate Bhargava test statistic or the suitably normalised OLS estimator of the unit root has higher power than the Dickey-Fuller or augmented Dickey-Fuller t-tests. In particular, in models with a trend, an increase in the mean shift does not reduce the power of Bhargava's R2 test as much as it reduces the power of the other tests. Estimated response surfaces summarise the likely power loss due to any particular mean shift.

description: A parametric specification of an indirect utility function in terms of expenditure and two unit cost functions.is.proposed. Specification of these unit cost functions in terms of regular functions leads to the notion of an "effectively globally regular" system of demand equations; that is, a system of demand equations that is regular over a cone in expenditure-price space, and for which the regular region includes all points in any given sample, and all values of nominal expenditure and prices generating higher values of real expenditure than the sample minimum. This general model nests a number of popular demand systems, such as the Linear Expenditure System, as special cases. An empirical application demonstrates the value of the generalization.

description: The formation of meta-stable dark matter bound states in coannihilating scenarios could efficiently occur through the scattering with a variety of Standard Model bath particles, where light bosons during the electroweak cross over or even massless photons and gluons are exchanged in the t-channel. The amplitudes for those higher-order processes, however, are divergent in the collinear direction of the in- and out-going bath particles if the mediator is massless. To address the issue of collinear divergences, we derive the bound-state formation collision term in the framework of non-equilibrium quantum field theory. The main result is an expression for a more general cross section, which allows to compute higher-order bound-state formation processes inside the primordial plasma background in a comprehensive manner. Based on this result, we show that next-to-leading order contributions, including the bath-particle scattering, are i) collinear finite and ii) generically dominate over the on-shell emission for temperatures larger than the absolute value of the binding energy. Based on a simplified model, we demonstrate that the impact of these new effects on the thermal relic abundance is significant enough to make it worthwhile to study more realistic coannihilation scenarios.

It is proved that $¶H$ is self-adjoint and that its eigenvalues coincide (up to a sign) with the singular values of $H$, i.e. the eigenvalues of $\sqrt{H^\ast H}$. Moreover we explicitly construct the canonical expansion of $H$ and determine the singular values $μ_j$ of $H$ through the Borel summability of their divergent perturbation theory. The singular values yield estimates of the location of the eigenvalues $ł_j$ of $H$ by Weyl's inequalities.

Understanding QCD thermodynamics from QCD spectral properties has its own importance. Also it has a close connection to phenomenological analyses of the lattice data as well as experimental data on the basis of hadronic resonances. Our feasibility study shows that the MEM can provide a useful tool to study QCD level density.

description: Electromagnetic inverse problems involve determining the location and identifying the shape and parameters of hidden conducting objects. Low-frequency, low-conductivity applications, range from geophysical applications, such as electric resistivity imaging (ERI), including groundwater detection or minerals and oil identification, to medical imaging problems using electrical impedance tomography (EIT). EIT consists of finding the conductivity contrast between an anomaly and a healthy tissue from voltage measurements around the patient body. For EIT, the perturbed electrical potential field (which is related to the voltage measurements) can be described by an asymptotic expansion as the size of an isolated inclusion goes to 0, which the leading order term separating into the gradient of a free-space Green's function, the gradient of the background potential field at the position of the object and the polarization tensor. In this work, we present an adaptive boundary element mesh algorithm to compute the polarization tensor accurately using BEM++. Moreover, the relationship of the computational discretisation of the object is investigated through a series of numerical experiments.

description: Positive geometries provide a modern approach for computing scattering amplitudes in a variety of physical models. In order to facilitate the exploration of these new geometric methods, we introduce a Mathematica package called ``amplituhedronBoundaries'' for calculating the boundary structures of three positive geometries: the amplituhedron $\mathcal{A}_{n,k}^{(m)}$, the momentum amplituhedron $\mathcal{M}_{n,k}^{(m)}$ and the hypersimplex $Δ_{k,n}$. The first two geometries are relevant for scattering amplitudes in planar $\mathcal{N}=4$ SYM, while the last one is a well-studied polytope appearing in many contexts in mathematics, and is closely related to $\mathcal{M}_{n,k}^{(2)}$. The package includes an array of useful tools for the study of these positive geometries, including their boundary stratifications, drawing their boundary posets, and additional tools for manipulating combinatorial structures useful for positive Grassmannians.

description: We have analyzed the intra-group light component of 3 Hickson Compact Groups (HCG 79, HCG 88 and HCG 95) with detections in two of them: HCG 79, with $46\pm11%$ of the total $B$ band luminosity and HCG 95 with $11\pm26%$. HCG 88 had no component detected. This component is presumably due to tidally stripped stellar material trapped in the group potential and represents an efficient tool to determine the stage of dynamical evolution and to map its gravitational potential. To detect this low surface brightness structure we have applied the wavelet technique OV\_WAV, which separates the different components of the image according to their spatial characteristic sizes.

description: Working in conjunction with the UBC Food System Project, we, group 3, have conducted research to determine whether rooftop gardens at UBC would decrease greenhouse gas emission, help with climate change, and move UBC beyond carbon neutral. In the project, interviews with highly respectable and professional individuals, such as Ted Cathcart and Tara Moreau, were conducted and calculations were done to evaluate the carbon emission associated with the transportation of food. This allowed the group to determine if having edible landscapes at UBC would truly move UBC beyond climate neutral. It was found that edible landscapes could potentially assist with these goals; however, factors such as appropriate crops, suitable buildings and available resources would need to be carefully chosen and assessed in order to successfully include edible landscapes on UBC campus. Furthermore, preliminary calculations reveal that rooftop gardens, community gardens alike, will do very little to reduce the campus’ dependency on imported food. This report includes useful information regarding the building of edible landscapes and the carbon emission caused by transportation; furthermore, it also contains recommendations that promote further research, initiate sustainable practices, and include more local food sources. These proposals and recommendation set forth will help future AGSC 450 to effectively move UBC beyond carbon neutral.

description: We review the problem of stripe states in strongly correlated systems,and some of the theoretical, numerical and experimental methods used in the last few years to understand these states. We compare these states to more traditional charge-ordered states such as charge density waves (CDW) and phase-separated systems. We focus on the origin of stripe states as an interplay between magnetic and kinetic energy, and argue that the stripe state is generated via a mechanism of kinetic energy release that can be described via strongly correlated models such as the t-J model. We also discuss phenomenological models of stripes, and their relevance for magnetism and for the pinning of stripes by the underlying lattice and by disordered impurities. Recent experimental evidence for the existence of stripe states in different cuprate systems is also reviewed.

description: Both experiments CDF and D0 at the Tevatron collider have now the first samples of B_s particles where preliminary measurements are performed. The mass and lifetime measurements are presented and the yield for the hadronic B_s decays, the first step toward the B_s production fraction and branching ratio measurements, is discussed.

description: We calculate exponential growth constants $ϕ$ and $σ$ describing the asymptotic behavior of spanning forests and connected spanning subgraphs on strip graphs, with arbitrarily great length, of several two-dimensional lattices, including square, triangular, honeycomb, and certain heteropolygonal Archimedean lattices. By studying the limiting values as the strip widths get large, we infer lower and upper bounds on these exponential growth constants for the respective infinite lattices. Since our lower and upper bounds are quite close to each other, we can infer very accurate approximate values for these exponential growth constants, with fractional uncertainties ranging from $O(10^{-4})$ to $O(10^{-2})$. We show that $ϕ$ and $σ$, are monotonically increasing functions of vertex degree for these lattices.

description: The generation of surface plasmon polaritons (SPP's) at isolated nanoholes in 100 nm thick Au films is studied using near-field scanning optical microscopy (NSOM). Finite-difference time-domain calculations, some explicitly including a model of the NSOM tip, are used to interpret the results. We find the holes act as point-like sources of SPP's and demonstrate that interference between SPP's and a directly transmitted wave allows for determination of the wavelength, phase, and decay length of the SPP. The near-field intensity patterns can be manipulated by varying the angle and polarization of the incident beam.

Kinetic Theory of a Spin-1/2 Bose-Condensed Gas

Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We derive a kinetic theory for a spin-1/2 Bose-condensed gas of two-level atoms at finite temperatures. The condensate dynamics is described by a generalized Gross-Pitaevskii equation for the two-component spinor order parameter, which includes the interaction with the uncondensed fraction. The noncondensate atoms are described by a quantum kinetic equation, which is a generalization of the spin kinetic equation for spin-polarized quantum gases to include couplings to the condensate degree of freedom. The kinetic equation is used to derive hydrodynamic equations for the noncondensate spin density. The condensate and noncondensate spins are coupled directly through the exchange mean field. Collisions between the condensate and noncondensate atoms give rise to an additional contribution to the spin diffusion relaxation rate. In addition, they give rise to mutual relaxation of the condensate and noncondensate due to lack of local equilibrium between the two components.

Production of the X(3872) in B Meson Decay by the Coalescence of Charm Mesons

description: If the recently-discovered charmonium state X(3872) is a loosely-bound S-wave molecule of the charm mesons \bar D^0 D^{*0} or \bar D^{*0} D^0, it can be produced in B meson decay by the coalescence of charm mesons. If this coalescence mechanism dominates, the ratio of the differential rate for B^+ \to \bar D^0 D^{*0} K^+ near the \bar D^0 D^{*0} threshold and the rate for B^+ \to X K^+ is a function of the \bar D^0 D^{*0} invariant mass and hadron masses only. The identification of the X(3872) as a \bar D^0 D^{*0}/\bar D^{*0} D^0 molecule can be confirmed by observing an enhancement in the \bar D^0 D^{*0} invariant mass distribution near the threshold. An estimate of the branching fraction for B^+ \to X K^+ is consistent with observations if X has quantum numbers J^{PC} = 1^{++} and if J/ψπ^+ π^- is one of its major decay modes.
