description: A mathematical model based on the equations of hydrodynamics combined with the fuzzy set theory was formulated, for the flood wave propagation in natural rivers. The model is able to evaluate the behavior of the control variables as membership functions. For the solution of the model governing partial differential equations, the Finite Difference Method was used, and for the solution of the resulting system of nonlinear algebraic equations, the Newton-Raphson Iteration Method was used. The results show that the use of Fuzzy Set Theory in the Hydrodynamic model could be an available alternative to determination of the uncertainty and to the Fuzzy Risk Analysis in the flood wave propagation.

description: Knowledge reduction of dynamic covering information systems involves with the time in practical situations. In this paper, we provide incremental approaches to computing the type-1 and type-2 characteristic matrices of dynamic coverings because of varying attribute values. Then we present incremental algorithms of constructing the second and sixth approximations of sets by using characteristic matrices. We employ experimental results to illustrate that the incremental approaches are effective to calculate approximations of sets in dynamic covering information systems. Finally, we perform knowledge reduction of dynamic covering information systems with the incremental approaches.
Why be good? the development of enlightened self-interest in moral personality
Creators: name: Frimer, Jeremy Abraham
Publisher: name: University of British Columbia
Year: 2011

description: What motivates people to devote their lives to promoting the greater good? This dissertation advances the reconciliation model, which explains moral motivation within a developmental framework by positing that, for the mature, the relationship between self-promoting (agentic) and other-promoting (communal) motives transforms from one of mutual competition to one of synergy. That is, the model proposes that moral exemplars, in particular, integrate agency and communion in their psychological functioning. Most people, on the other hand, do not become highly virtuous partly because they developmentally stagnate, failing to integrate these motives. The majority of leaders and other successful people also fail to integrate the two, and instead continue to develop agentic motives while attenuating communal motives, resulting in unmitigated agency. Three studies test claims concerning the endpoints of development. Relying on a young-adult sample of student club leaders, Study 1 pinpoints the specific values that usually compete within the moral domain. Study 2 finds evidence of integrated agency and communion in the personalities of recipients of a national award for decades of contribution to the greater good (in contrast to a demographically matched comparison group). Study 3 explores the motives of a “moral dream team” compared to those of a similarly influential set of heroes, icons, leaders, and revolutionaries. The findings are that exemplars treat agency as a means to an end of communion while, for most influential people, agency merely begets more agency. Agency, communion, and the relationship between them hold considerable promise in explaining moral motivation, its development, and the processes that support lives of extraordinary moral commitment.

subject: Medicine

description: Background: A sensory trick, or geste antagoniste, is defined as a physical gesture (such as a touch on a particular body part) that mitigates the production of an involuntary movement. This phenomenon is most commonly described as a feature of dystonia. Here we present a case of successful modulation of tics using sensory tricks.
Case Report:: A case report and video are presented. The case and video demonstrate a 19-year-old male who successfully controlled his tics with various sensory tricks.
Discussion: It is underappreciated by movement disorder physicians that sensory tricks can play a role in tics. Introducing this concept to patients could potentially help in tic control. In addition, understanding the pathophysiological underpinnings of sensory tricks could help in the understanding of the pathophysiology of tics.

description: We study the stochastic evolution of four species in cyclic competition in a well mixed environment. In systems composed of a finite number $N$ of particles these simple interaction rules result in a rich variety of extinction scenarios, from single species domination to coexistence between non-interacting species. Using exact results and numerical simulations we discuss the temporal evolution of the system for different values of $N$, for different values of the reaction rates, as well as for different initial conditions. As expected, the stochastic evolution is found to closely follow the mean-field result for large $N$, with notable deviations appearing in proximity of extinction events. Different ways of characterizing and predicting extinction events are discussed.

description: Given a collection $\{λ_1, \dots, λ_n\} $ of real numbers, there is a canonical probability distribution on the set of real symmetric or complex Hermitian matrices with eigenvalues $λ_1,\ldots,λ_n$. In this paper, we study various features of random matrices with this distribution. Our main results show that under mild conditions, when $n$ is large, linear functionals of the entries of such random matrices have approximately Gaussian joint distributions. The results take the form of upper bounds on distances between multivariate distributions, which allows us also to consider the case when the number of linear functionals grows with $n$. In the context of quantum mechanics, these results can be viewed as describing the joint probability distribution of the expectation values of a family of observables on a quantum system in a random mixed state. Other applications are given to spectral distributions of submatrices, the classical invariant ensembles, and to a probabilistic counterpart of the Schur--Horn theorem, relating eigenvalues and diagonal entries of Hermitian matrices.

description: The discovery of very-high-energy (VHE, E > 100 GeV) gamma-ray emission from intermediate- and low-frequency peaked blazars suggests that gamma-gamma absorption and pair cascading might occur in those objects. In previous papers, we investigated the Compton emission from VHE gamma-ray induced pair cascades, deflected by moderate magnetic fields, in a largely model-independent way, and demonstrated that this emission can explain the Fermi fluxes and spectra of the radio galaxies Cen A and NGC 1275. In this paper, we describe a generalization of our Monte-Carlo cascade code to include the angle-dependent synchrotron output from the cascades, allowing for the application to situations with non-negligible magnetic fields, leading to potentially observable synchrotron signatures, but still not dominating the radiative energy loss of cascade particles. We confirm that the synchrotron radiation from the cascades in NGC 1275 and Cen A are negligible for the parameters used in our previous works. We demonstrate that the magnetic field can not be determined from a fit of the cascade emission to the gamma-ray spectrum alone, and the degeneracy can only be lifted if the synchrotron emission from the cascades is observed as well. We illustrate this fact with the example of NGC 1275. We point out that the cascade synchrotron emission may produce spectral features in the same energy range in which the big blue bump is observed in the spectral energy distributions of several blazars, and may make a non-negligible contribution to this feature. We illustrate this idea with the example of 3C 279.

Support vector machines for petrophysical modelling and lithoclassification

description: Given increasing challenges of oil and gas production from partially depleted conventional or unconventional reservoirs, reservoir characterization is a key element of the reservoir development workflow. Reservoir characterization impacts well placement, injection and production strategies, and field management. Reservoir characterization projects point and line data to a large three-dimensional volume. The relationship between variables, e.g. porosity and permeability, is often established by regression yet the complexities between measured variables often lead to poor correlation coefficients between the regressed variables. Recent advances in machine learning methods have provided attractive alternatives for constructing interpretation models of rock properties in heterogeneous reservoirs. Here, Support Vector Machines (SVMs ), a class of a learning machine that is formulated to output regression models and classifiers of competitive generalization capability, has been explored to determine its capabilities for determining the relationship, both in regression and in classification, between reservoir rock properties. This thesis documents research on the capability of SVMs to model petrophysical and elastic properties in heterogeneous sandstone and carbonate reservoirs. Specifically, the capabilities of SVM regression and classification has been examined and compared to neural network-based methods, namely multilayered neural networks, radial basis function neural networks, general regression neural networks, probabilistic neural networks, and linear discriminant analysis. The petrophysical properties that have been evaluated include porosity, permeability, Poisson's ratio and Young's modulus. Statistical error analysis reveals that the SVM method yields comparable or superior predictions of petrophysical and elastic rock properties and classification of the lithology compared to neural networks. The SVM method also shows uniform prediction capability under the effect of small sample sizes.

description: The probabilistic bulk convection model (PBCM) developed in a companion paper is here extended to shallow nonprecipitating convection. The PBCM unifies the clear-sky and shallow convection boundary layer regimes by obtaining mixed-layer growth, cloud fraction, and convective inhibition from a single parameterization based on physical principles. The evolution of the shallow convection PBCM is based on the statistical distribution of the surface thermodynamic state of convective plumes.

The entrainment velocity of the mixed layer is related to the mass flux of the updrafts overshooting the dry inversion capping the mixed layer. The updrafts overcoming the convective inhibition generate active cloud-base mass flux, which is the boundary condition for the shallow cumulus scheme. The subcloud-layer entrainment velocity is directly coupled to the cloud-base mass flux through the distribution of vertical velocity and fractional cover of the updrafts.

Comparisons of the PBCM against large-eddy simulations from the Barbados Oceanographic and Meteorological Experiment (BOMEX) and from the Southern Great Plains Atmospheric Radiation Measurement Program (ARM) facility demonstrate good agreement in terms of thermodynamic structure, cloud-base mass flux, and cloud top.

The equilibrium between the cloud-base mass flux and rate of growth of the mixed layer determines the equilibrium convective inhibition and cloud cover. This process is an important new insight on the coupling between the mixed-layer and cumulus dynamics. Given its relative simplicity and transparency, the PBCM represents a powerful tool for developing process-based understanding and intuition about the physical processes involved in boundary layer–convection interactions, as well as a test bed for diagnosing and validating shallow convection parameterizations.
Experimental and modeling studies of drug delivery into tissues using microneedle arrays

Publisher: name: University of Calgary

description: Bibliography: p. 104-118
description: Effectively delivering drugs into target tissues or organs of the human body is still a major challenge in medical science. Microneedles, fabricated using microfabrication technology, are being developed as a novel and promising alternative for painless fluid injection or extraction. Over the past few years, various microneedle arrays have been fabricated by employing materials such as silicon, metals, polymers and glass with feature sizes ranging from sub-micron to millimeters. In this research, both experimental and modeling studies are carried out in continuous flow for drug delivery into target tissues using microneedle arrays. The major contributions of this work are as follows: Firstly, there is a need for high precision pumping at low flow rates (0-500 µl/min) for drug delivery using microneedle arrays. We design, simulate, fabricate and test an AC electrothermal (ACET) micropump for fluidic control. For ACET micropumping, microfabricated electrode arrays are used to generate high strength AC electric fields. A coplanar electrode array design can limit the fabrication and operational complexity of the devices. Thus, different fluidic components may be integrated on one substrate, with a minimum of assembly for future applications. Secondly, accurately modeling liquid characteristics of microfuidic devices is difficult, as they exhibit complicated multiphase behaviour. When combined with the requirement for modeling drug delivery into target tissues of the human body using a complex microneedle array, the modeling becomes complicated. For this study, a mathematical model is developed to model and simulate microneedle liquid delivery into tissue by using mixture theory to better understand the working performance of the microneedle array and its interaction with tissue for drug delivery applications. Lastly, experiments with ACET micropumping are carried out to verify the simulation results. The conducted experiments are in good agreement with the simulations providing accurate determination of fluid flow changes with variable parameters and forcing functions.

description: Background: Sydenham's chorea (SC) is the most common type of acquired chorea in childhood. In some cases, symptoms (most commonly described in terms of neurological signs) last up to 2 years, and many cases relapse. This report describes the clinical course in terms of functional abilities following diagnosis of SC.
Case report: Standardized assessments across the domains of activity and participation were administered following diagnosis, prior to and following treatment with haloperidol to measure treatment response and identify occupational therapy intervention needs. SC was observed to significantly reduce the child's participation and independence in activities of daily living. In this case, the standardized assessments administered highlighted difficulties with both motor and process skills. At 1 week after commencing haloperidol, both motor and process skills had improved. Clinically significant changes in self-care and mobility were noted with less improvement with handwriting. At 9 weeks, most symptoms and functional difficulties had resolved.
Discussion: Given the process difficulties detected in this case, and the possibility of enduring symptoms, the use of functional assessments is advocated in the routine management of SC. These findings illustrate the potential for motor and non-motor sequelae in acute childhood movement disorders and related functional disabling consequences.

description: Background: Movement disorders, particularly those associated with basal ganglia disease, have a high rate of comorbid neuropsychiatric illness.
Methods: We consider the pathophysiological basis of the comorbidity between movement disorders and neuropsychiatric illness by 1) reviewing the epidemiology of neuropsychiatric illness in a range of hyperkinetic movement disorders, and 2) correlating findings to evidence from studies that have utilized modern neuroimaging techniques to investigate these disorders. In addition to diseases classically associated with basal ganglia pathology, such as Huntington disease, Wilson disease, the neuroacanthocytoses, and diseases of brain iron accumulation, we include diseases associated with pathology of subcortical white matter tracts, brain stem nuclei, and the cerebellum, such as metachromatic leukodystrophy, dentatorubropallidoluysian atrophy, and the spinocerebellar ataxias.
Conclusions: Neuropsychiatric symptoms are integral to a thorough phenomenological account of hyperkinetic movement disorders. Drawing on modern theories of cortico-subcortical circuits, we argue that these disorders can be conceptualized as disorders of complex subcortical networks with distinct functional architectures. Damage to any component of these complex information-processing networks can have variable and often profound consequences for the function of more remote neural structures, creating a diverse but nonetheless rational pattern of clinical symptomatology.

description: We use shift-invariant subspaces of the Hardy space on the bidisk to provide an elementary proof of the Agler Decomposition Theorem. We observe that these shift-invariant subspaces are specific cases of Hilbert spaces that can be defined from Agler decompositions and analyze the properties of such Hilbert spaces. We then restrict attention to rational inner functions and show that the shift-invariant subspaces provide easy proofs of several known results about decompositions of rational inner functions. We use our analysis to obtain a result about stable polynomials on the polydisk.

Leukocyte telomere length (LTL) in blood samples was measured by quantitative PCR and presented in kilobase pairs (kbp) after transformation. Weight change patterns from 10 years before the survey to baseline (mean age 51 years) were defined according to body mass index (BMI) category changes or absolute weight changes between the two time points. Survey-weighted multivariable linear regression with adjustments for potential confounders was utilized.This study found that weight change in 10-year period was associated with leukocyte telomere length and supports the theory that weight gain promotes aging across adulthood.

Publisher: name: Columbia University
Year: 2012
Subjects: Paleoclimatology

description: The reconstruction of deep-sea bottom water temperature (BWT) is important to assess the ocean's response to and role in orbital- and millennial-scale climate change. Deep-sea paleothermometry employs magnesium to calcium (Mg/Ca) ratios in calcitic benthic microfaunas (foraminifera, ostracodes) as a primary proxy method. Mg/Ca paleothermometry may, however, be complicated by bottom water carbonate ion chemistry, which might affect Mg/Ca ratios in shells. To address temperature and carbonate ion influence on Mg/Ca ratios, we studied Mg/Ca ratios in the benthic ostracode genus Krithe in the North Atlantic and Arctic oceans using a 686-specimen core top collection, including 412 previously unpublished analyses. Mg/Ca ratios are positively correlated to temperature in multiple species from the North Atlantic [BWT = (0.885 × Mg/Ca) − 5.69, r2 = 0.73] and for K. glacialis in the Arctic Ocean and Nordic Seas [BWT = (0.439 × Mg/Ca) − 5.14, r2 = 0.50], consistent with previously published calibrations. We found no evidence for a relationship between Krithe Mg/Ca and carbonate ion saturation in the North Atlantic Ocean, Nordic Seas, and Arctic Ocean, supporting the use of Krithe Mg/Ca for reconstructing past BWT.

description: We reconstructed subsurface (∼200–400 m) ocean temperature and sea-ice cover in the Canada Basin, western Arctic Ocean from foraminiferal δ18O, ostracode Mg/Ca ratios, and dinocyst assemblages from two sediment core records covering the last 8000 years. Results show mean temperature varied from −1 to 0.5°C and −0.5 to 1.5°C at 203 and 369 m water depths, respectively. Centennial-scale warm periods in subsurface temperature records correspond to reductions in summer sea-ice cover inferred from dinocyst assemblages around 6.5 ka, 3.5 ka, 1.8 ka and during the 15th century Common Era. These changes may reflect centennial changes in the temperature and/or strength of inflowing Atlantic Layer water originating in the eastern Arctic Ocean. By comparison, the 0.5 to 0.7°C warm temperature anomaly identified in oceanographic records from the Atlantic Layer of the Canada Basin exceeded reconstructed Atlantic Layer temperatures for the last 1200 years by about 0.5°C.

description: Doppler cooling on a narrow transition is limited by the noise of single scattering events. It shows novel features, which are in sharp contrast with cooling on a broad transition, such as a non-Gaussian momentum distribution, and divergence of its mean square value close to the resonance. We have observed those features using 1D cooling on an intercombination transition in strontium, and compared the measurements with theoretical predictions and Monte Carlo simulations. We also find that for a very narrow transition, cooling can be improved using a dipole trap, where the clock shift is canceled.

description: Background Hereditary coproporphyria (HCPO) is a low‐penetrance, autosomal dominant, acute hepatic porphyria characterized by the overproduction and excretion of coproporphyrin. The most common neurological manifestations of this entity include peripheral, predominantly motor dysfunction, and central nervous system dysfunction. Ataxia associated with HCPO has not been reported previously. The aim of this article is to report a patient with HCPO presenting with acute ataxia. Case Report We describe a 44‐year‐old patient presenting clinically with acute ataxia who was diagnosed with HCPO; mutations were analyzed in the coproporphyrin‐oxidase III (CPOX) gene in the patient and in six asymptomatic first‐degree relatives. Discussion The patient was heterozygous for a mutation causing the amino acid exchange Q306X in the CPOX gene. No relatives carried the same or another mutation in the CPOX gene. HCPO should be considered in the differential diagnosis for patients presenting with ataxia.

description: Given a 3-manifold $M$ fibering over the circle, we investigate how the asymptotic translation lengths of pseudo-Anosov monodromies in the arc complex vary as we vary the fibration. We formalize this problem by defining normalized asymptotic translation length functions $μ_d$ for every integer $d \ge 1$ on the rational points of a fibered face of the unit ball of the Thurston norm on $H^1(M;\mathbb{R})$. We show that even though the functions $μ_d$ themselves are typically nowhere continuous, the sets of accumulation points of their graphs on $d$-dimensional slices of the fibered face are rather nice and in a way reminiscent of Fried's convex and continuous normalized stretch factor function. We also show that these sets of accumulation points depend only on the shape of the corresponding slice. We obtain a particularly concrete description of these sets when the slice is a simplex. We also compute $μ_1$ at infinitely many points for the mapping torus of the simplest hyperbolic braid to show that the values of $μ_1$ are rather arbitrary. This suggests that giving a formula for the functions $μ_d$ seems very difficult even in the simplest cases.

Beyond pixels and regions: A non local patch means (NLPM) method for content-level restoration, enhancement, and reconstruction of degraded document images

description: A patch-based non-local restoration and reconstruction method for preprocessing degraded document images is introduced. The method collects relative data from the whole input image, while the image data are first represented by a content-level descriptor based on patches. This patch-equivalent representation of the input image is then corrected based on similar patches identified using a modified genetic algorithm (GA) resulting in a low computational load. The corrected patch-equivalent is then converted to the output restored image. The fact that the method uses the patches at the content level allows it to incorporate high-level restoration in an objective and self-sufficient way. The method has been applied to several degraded document images, including the DIBCO'09 contest dataset with promising results.

description: Elevators are awkward spaces. There are unspoken rules about what behaviour is acceptable while riding with a stranger. If these rules are broken, the remainder of the elevator ride becomes unbelievably uncomfortable. If a stranger casts their gaze in any direction other than towards the doors, this can threaten the delicate agreement that tacitly exists between the occupants of the elevator, turning the mood into an emotional pressure cooker. A Delicate Agreement is a gaze-triggered interactive art installation that explores this concept. It is a set of elevator doors with a peephole in either side that entices viewers to peer inside and observe an animation of the passengers. Each elevator passenger, or character, has a programmed personality that enables them to act and react to the other characters' behaviour and the viewers' gaze. The result is the emergence of a rich interactive narrative made up of encounters between the characters.

description: The onset of moist convection over land is investigated using a conceptual approach with a slab boundary layer model. We here determine the essential factors for the onset of boundary layer clouds over land, and study their relative importance. They are: 1) the ratio of the temperature to the moisture lapse rates of the free troposphere, i.e. the inversion Bowen ratio, 2) the mean-daily surface temperature, 3) the relative humidity of the free troposphere and 4) the surface evaporative fraction. A clear transition is observed between two regimes of moistening of the boundary layer as assessed by the relative humidity at the boundary layer top. In the first so-called wet soil advantage regime, the moistening results from the increase of the mixed-layer specific humidity, which linearly depends on the surface evaporative fraction and inversion Bowen ratio through a dynamic boundary layer factor. In the second so-called dry soil advantage regime, the relative humidity tendency at the boundary layer top is controlled by the thermodynamics and changes in the moist adiabatic induced by the decreased temperature at the boundary layer top and consequent reduction in saturation water vapor pressure. This regime pertains for very deep boundary layers under weakly stratified free troposphere over hot surface conditions. In the context of the conceptual model, a rise in free-tropospheric temperature (global warming) increases the occurrence of deep convection and reduces the cloud cover over moist surfaces. This study provides new intuition and predictive capacity on the mechanism controlling the occurrence of moist convection over land.
A Unified Framework for Generalizing the Gromov-Hausdorff Metric

description: In this paper, an approach for generalizing the Gromov-Hausdorff metric is presented, which applies to metric spaces equipped with some additional structure. A special case is the Gromov-Hausdorff-Prokhorov metric between measured metric spaces. This abstract framework unifies several existing Gromov-Hausdorff-type metrics for metric spaces equipped with a measure, a point, a closed subset, a curve, a tuple of such structures, etc. Along with reviewing these special cases in the literature, several new examples are also presented. Two frameworks are provided, one for compact metric spaces and the other for boundedly-compact pointed metric spaces. In both cases, a Gromov-Hausdorff-type metric is defined and its topological properties are studied. In particular, completeness and separability is proved under some conditions. This enables one to study random metric spaces equipped with additional structures, which is the main motivation of this work.

Study of diffusivity of hydrocarbon solvent in heavy oil saturated sands using computer assisted tomography

description: Hydrocarbon solvent-assisted processes are thought to be effective EOR technologies for heavy oil and bitumen production. In order to describe those processes quantitatively, the diffusivity of hydrocarbon solvent in oil sands is a required crucial parameter. The effective diffusivity in porous media is smaller than the true diffusivity in bulk fluids. However, good-quality data from diffusion experiments of heavy oil and solvent for effective diffusivity determination in porous media is still scarce. This thesis includes two sections. The first section discusses the impact of volume changes due to mixing on diffusivity of liquid solvent in heavy oil. The second section presents diffusion experiments of liquid solvent in heavy oil saturated sandpacks using X-ray Computer Assisted Tomography (CAT), and determines the effective diffusivity based on an updated approach, which implies extended diffusion model and new data processing method considering porosity variation of sandpacks and volume changes on mixing. Subsequently the relationship between the effective diffusivity and the molecular diffusivity is investigated.

description: Clinical trials investigating whether glucose lowering treatment reduces the risk of CVD in diabetes have thus far yielded mixed results. However, this doesn't rule out the possibility of hyperglycemia playing a major causal role in promoting CVD or elevating CVD risk. In fact, lowering glucose appears to promote some beneficial long-term effects, and continuous glucose monitoring devices have revealed that postprandial spikes of hyperglycemia occur frequently, and may be an important determinant of CVD risk. It is proposed that these short, intermittent bursts of hyperglycemia may have detrimental effects on several organ systems including the vasculature and the hematopoietic system collectively contributing to the state of elevated CVD risk in diabetes. In this review, we summarize the potential mechanisms through which hyperglycemic spikes may increase atherosclerosis and how new and emerging interventions may combat this.
