Scrolling in radiology image stacks : multimodal annotations and diversifying control mobility
Creators: name: Oram, Louise Carolyn
Publisher: name: University of British Columbia
Year: 2013

description: Advances in image acquisition technology mean that radiologists today must examine thousands of images to make a diagnosis. However, the physical interactions performed to view these images are repetitive and not specialized to the task. Additionally, automatic and/or radiologist-generated annotations may impact how radiologists scroll through image stacks as they review areas of interest. We analyzed manual aspects of this work by observing and/or interviewing 19 radiologists; stack scrolling dominated the resulting task examples. We used a simplified stack seeded with correct or incorrect annotations in our experiment on lay users. The experiment investigated the impact of four scrolling techniques: traditional scrollwheel, click+drag, sliding-touch and tilting to access rate control. We also examined the effect of visual vs. haptic annotation cues’ on scrolling dynamics, detection accuracy and subjective factors. Scrollwheel was the fastest scrolling technique overall for our lay participants. Combined visual and haptic annotation highlights increased the speed of target-finding in comparison to either modality alone. Multimodal annotations may be useful in radiology image interpretation; users are heavily visually loaded, and there is background noise in the hospital environment. From interviews with radiologists, we see that they are receptive to a mouse that they can use to map different movements to interactions with images as an alternative to the standard mouse usually provided with their workstation.

description: An active load pull system is presented for measuring devices from 50 um to 1 mm gate width in Ka Band. It permits in a first configuration to measure the scattering parameters in small- and large-signal conditions. In the other configuration, it permits to extract all gains, power levels, impedances of interest, average currents and efficiencies for a given device, even for very large gate width. It can scan automatically the interesting area of the Smith chart. The system protects the tested devices because the impedance is presented at the output of the device only if the gate current is lower than a fixed value.
A novel fast search algorithm for an active load-pull measurement system
Creators: name: De Hek, A.P.
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 1998
Subjects: ING-INF/01 Elettronica

description: In this paper a novel fast search algorithm for an active load-pull algorithm is presented. This algorithm is based on the fact that it is possible to fit, with a minimum number of measurements, the desired parameter, for instance the output power, as function of the load reflection coefficient. The fitted function is used to make a prediction of the location of the optimum load reflection coefficient. Application of the novel load-pull algorithm has resulted in a 8 time reduced measurement time. In this paper also the load-pull measurement system installed at TNO-FEL and some measurement results obtained with the described search algorithm are discussed.

description: We present a systematic study of the effects due to initial condition fluctuations in systems formed by heavy-ion collisions using the hydrodynamical simulation code NeXSPheRIO. The study was based on a sample of events generated simulating Au+Au collisions at center of mass energy of 200 GeV per nucleon pair with impact parameter ranging from most central to peripheral collisions. The capability of the NeXSPheRIO code to control and save the initial condition (IC) as well as the final state particles after the 3D hydrodynamical evolution allows for the investigation of the sensitivity of the experimental observables to the characteristics of the early IC. Comparisons of results from simulated events generated using fluctuating initial conditions and smooth initial condition are presented for the experimental observable elliptic flow parameter ($v_2$) as a function of the transverse momentum, $p_t$, and centrality. We compare $v_2$ values estimated using different methods, and how each method responds to effects of fluctuations in the initial condition. Finally, we quantify the flow fluctuations and compare to the fluctuations of the initial eccentricity of the energy density distribution in the transverse plane.

description: The Ambrosia Fusarium Clade (AFC) is a monophyletic lineage within clade 3 of the Fusarium solani species complex (FSSC) that currently comprises 19 genealogically exclusive species. These fungi are known or predicted to be farmed by adult female Euwallacea ambrosia beetles as a nutritional mutualism (Coleoptera: Scolytinae; Xyleborini). To date, only eight of the 19 AFC species have been described formally with Latin binomials. We describe three AFC species, previously known as AF-8, AF-10, and AF-11, based on molecular phylogenetic analysis of multilocus DNA sequence data and comparative morphological/phenotypic studies. Fusarium duplospermum (AF-8) farmed by E. perbrevis on avocado in Florida, USA, is distinguished by forming two morphologically different types of multiseptate conidia and brownish orange colonies on potato dextrose agar (PDA). Fusarium drepaniforme (AF-10), isolated from an unknown woody host in Singapore and deposited as Herb IMI 351954 in the Royal Botanic Gardens, Kew, UK, under the name F. bugnicourtii, is diagnosed by frequent production of multiseptate sickle-shaped conidia. Fusarium papillatum (AF-11), isolated from mycangia of E. perbrevis infesting tea in Kandy, Sri Lanka, forms multiseptate clavate conidia that possess a papillate apical cell protruding toward the ventral side. Lastly, we prepared an augmented description of F. kuroshium (AF-12), previously isolated from the heads or galleries of E. kuroshio in a California sycamore tree, El Cajon, California, USA, and recently validated nomenclaturally as Fusarium. Conidia formed by F. kuroshium vary widely in size and shape, suggesting a close morphological relationship with F. floridanum, compared with all other AFC species. Maximum likelihood and maximum parsimony analyses of a multilocus data set resolve these three novel AFC species, and F. kuroshium, as phylogenetically distinct based on genealogical concordance. Given the promiscuous nature of several Euwallacea species, and the overlapping geographic range of several AFC species and Euwallacea ambrosia beetles, the potential for symbiont switching among sympatric species is discussed.

description: A new Tuner type for "Harmonic Tuning" is presented. It generates high VSWR at 2fo and 3fo as required for harmonic load pull. The new tuners can be precalibrated and appropriate interpolation routines ensure high-resolution coverage of 360 ° of harmonic reflection phase. The harmonic tuners use a proprietary resonant cavity as a variable probe, which covers instantaneous bandwidth of = 10% in the frequency range from 400 MHz to over 60 GHz. The new tuners can be built as "stand-alone two-harmonic frequency " units or they can be "combined with fundamental tuners". A new concept for tuner calibration allows us to fully characterize the harmonic and the "combo " tuners in about 4 to 8 minutes per frequency point (including fo, 2fo, 3fo). The new tuners permit to search and optimize the harmonic load and source impedance independently on fundamental tuning and provide test data for substantial design improvements in terms of Gain, PAE and Intermod.

Collapse of the quantum correlation hierarchy links entropic uncertainty to entanglement creation
Creators: name: Coles, Patrick J.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum correlations have fundamental and technological interest, and hence many measures have been introduced to quantify them. Some hierarchical orderings of these measures have been established, e.g., discord is bigger than entanglement, and we present a class of bipartite states, called premeasurement states, for which several of these hierarchies collapse to a single value. Because premeasurement states are the kind of states produced when a system interacts with a measurement device, the hierarchy collapse implies that the uncertainty of an observable is quantitatively connected to the quantum correlations (entanglement, discord, etc.) produced when that observable is measured. This fascinating connection between uncertainty and quantum correlations leads to a reinterpretation of entropic formulations of the uncertainty principle, so-called entropic uncertainty relations, including ones that allow for quantum memory. These relations can be thought of as lower-bounds on the entanglement created when incompatible observables are measured. Hence, we find that entanglement creation exhibits complementarity, a concept that should encourage exploration into "entanglement complementarity relations".

description: A complete procedure for the extraction of non-linear empirical models for MESFET's and HEMT's has been developed. The procedure requires DC and small signal S-parameters measurements to find model elements, and no cold measurements are needed for extrinsic parameters determination. The proposed procedure is able to deal with non-linear models characterised by low-frequency dispersion. The optimisation step aimed to determine the linear circuit model uses a multi-bias extraction. A software tool has been developed to check the algorithms and average errors of 4.8% for DC drain current and 8.4% for S-parameters have been obtained up to 5OGHz for a P-HEMT from PHILIPS PML-D02AH monolithic process.

description: This work for the first time shows that physically meaningful, wideband, multi-bias small-signal modeling of HBTs can be efficiently and accurately achieved using a Genetic Algorithm (GA). The physical significance of the equivalent circuit parameters extracted by the GA was checked using a Direct Extraction Technique (DET). The two procedures were applied to HBT S-parameters measured at different bias points. The simulated S-parameters match very well with the measured ones over the whole frequency range investigated. For each point we obtained quite a good agreement between the parameters extracted by the DET and by the GA, which demonstrates the ability of the GA to efficiently extract a physically significant HBT small-signal model.

An improved evolutionary Non-dominated Sorting Genetic Algorithm II (NSGA II), which is augmented with a chaotic map for greater effectiveness, is used for the multi-objective optimization problem. The Pareto fronts showing the trade-off between different design criteria are obtained for the PIλDμand PID controller. A comparative analysis is done with respect to the standard PID controller to demonstrate the merits and demerits of the fractional order PIλDμcontroller.

description: This letter presents an effective technique for the analysis of microwave and millimetre-wave field-effect transistors, based on geometrical and material data only. The intrinsic (active) part of the device is described by quasi-2D hydrodynamic transport equations, coupled to a numerical electromagnetic field solver in three dimensions that takes into account the passive (extrinsic) part of the structure, including connections and distributed propagation effects. The analysis is performed entirely in the time domain, and includes linear and non-linear operations of the device. Small-signal and large-signal results at microwave and millimetre-wave frequencies are presented for a 2x50 um HEMT device, and also for varying gate width, that demonstrate the capabilities of the technique. The feasibility of applications to the design and optimisation of high-frequency devices is demonstrated.

description: Excerpts from the report: Gray mold rot, caused by Botrytis cinerea Pers. ex Fr., occurs each year during the marketing of bell peppers. Such decay occurs as numerous lesions on the pods. Although peppers are readily infected through wounds such as broken stems and skin breaks, these lesions usually develop without the aid of visible skin breaks. The purpose of this study was to determine the factor or factors that predispose peppers to infection and decay. This was accomplished through studies on the effect of temperature on growth rate of Botrytis on nutrient agar, on the rate of decay when the fungus was inoculated into bell peppers through a wound, on percentage of pods that developed natural infection, and on infection from inoculation of nonwounded peppers.

We first study the identifiability of the Robin coefficient and then we establish a stability estimate of logarithm type thanks to a Carleman inequality due to A. L. Bukhgeim and under the assumption that the velocity of a given reference solution stays far from 0 on a part of the boundary where Robin conditions are prescribed.

description: For control systems that either have a fast explicit periodic dependence on time and bounded controls or have periodic solutions and small controls, we define an average control system that takes into account all possible variations of the control, and prove that its solutions approximate all solutions of the oscillating system as oscillations go faster. The dimension of its velocity set is characterized geometrically. When it is maximum the average system defines a Finsler metric, not twice differentiable in general. For minimum time control, this average system allows one to give a rigorous proof that averaging the Hamiltonian given by the maximum principle is a valid approximation.

description: The basic insight of the literature concerning the Median Voter Theorem and its applications, dating back to Black (1948), is that the policies implemented by different parties once in o¢ce should approach the median voter’s preferred policy if they run in a single-dimensional and democratic electoral space. This strong prediction has been challenged in recent years using arguments related to the observation that usually the political spaces concern much more than one single dimension and that, once we consider such a space, the Median Voter Theorem cannot be applied. Our idea is that one can challenge the median voter predictions even if we keep considering just one single dimension. Infect also in electoral competitions characterized by a very important issue seen by voters as "salient" is almost impossible to observe in reality the convergence predicted by the Black’s theorem. In the present model we introduce a simple assumption over the process of opinions’ formation of the voters and we show as in equilibrium strategic considerations lead the parties to choose polarized platforms.
Cyclical Strikes and Human Capital Accumulation under Asymmetric Information

Subjects: SECS-P/01 Economia politica

description: Strikes are totally inefficient from an economic point of view. They occur when the two parties that bargain over a contract do not find an agreement and the result is a loss of utility for both. In spite of their clear inefficiency in the real world strikes are very common both in the rich economies as well as in the poor countries. Moreover recent empirical literature found some regularities over time and over countries regarding the strike behavior of the Trade Unions. The aim of this paper is to develop a theory that could explain this apparent economic paradox as well as some of the most known regularities. At the same time we also aim to link the analysis of the strikes with the investment decisions of employers and workers in that particular kind of capital good known as Human Capital. This kind of approach can put under a new light the role played by the Trade Unions in the process of economic growth.

description: The nature of the second order phase transition that occurs in URu2Si2 at 17.5 K remains puzzling despite intensive research over the past two and half decades. A key question emerging in the field is whether a hybridization gap between the renormalized bands can be identified as the long-sought 'hidden' order parameter. We report on the measurement of a hybridization gap in URu2Si2 employing a spectroscopic technique based on quasiparticle scattering across a ballistic metallic junction. The differential conductance exhibits an asymmetric double-peak structure, a clear signature for a Fano resonance in a Kondo lattice. The extracted hybridization gap opens well above the transition temperature, indicating that it is not the hidden order parameter. Our results put stringent constraints on the origin of the hidden order transition in URu2Si2 and demonstrate that quasiparticle scattering spectroscopy can probe the band renormalizations in a Kondo lattice via detection of a novel type of Fano resonance.

description: We consider a coupled system of two singularly perturbed reaction-diffusion equations, with two small parameters $0< ε\le μ\le 1$, each multiplying the highest derivative in the equations. The presence of these parameters causes the solution(s) to have \emph{boundary layers} which overlap and interact, based on the relative size of $ε$ and $% μ$. We construct full asymptotic expansions together with error bounds that cover the complete range $0 < ε\leq μ\leq 1$. For the present case of analytic input data, we derive derivative growth estimates for the terms of the asymptotic expansion that are explicit in the perturbation parameters and the expansion order.

description: The fabrication of memristors by drop-coating sol-gel Ti(OH)$_4$ solution onto either aluminium foil or sputter-coated aluminium on plastic is presented. The gel layer is thick, 37$μ$m, but both devices exhibit good memristance I-V profiles. The drop coated aluminium foil memristors compare favourably with the sputter-coated ones, demonstrating an expansion in the accessibility of memristor fabrication. A comparison between aluminium and gold for use as the sputter-coated electrodes shows that aluminium is the better choice as using gold leads to device failure. The devices do not require a forming step.

description: We consider the K-satisfiability problem on a regular d-ary rooted tree. For this model, we demonstrate how we can calculate in closed form, the moments of the total number of solutions as a function of d and K, where the average is over all realizations, for a fixed assignment of the surface variables. We find that different moments pick out different 'critical' values of d, below which they diverge as the total number of variables on the tree goes to infinity and above which they decay. We show that K-SAT on the random graph also behaves similarly. We also calculate exactly the fraction of instances that have solutions for all K. On the tree, this quantity decays to 0 (as the number of variables increases) for any d>1. However the recursion relations for this quantity have a non-trivial fixed-point solution which indicates the existence of a different transition in the interior of an infinite rooted tree.

Modeling and active damping of structural vibrations in machine tools
Creators: name: Amir Hossein, Hadi Hosseinabadi
Publisher: name: University of British Columbia
Year: 2013

description: Feed drives of High Speed Machine (HSM) tools deliver fast motions for rapid positioning of tool or work-piece. The inertial forces generated by acceleration and deceleration of large machine tool components excite structural modes of the machine tools and cause residual vibrations. Unless avoided, the vibrations lead to poor surface finish and instability of the drive's control loop. In this thesis, structural flexibilities are represented by linear and torsional springs and dampers to develop a mathematical model of the feed drive dynamics. The model includes the contribution of structural vibrations in measuring table position by a linear encoder. An identification algorithm is introduced to facilitate the estimation of rigid body and structural dynamics in frequency domain. The identified mathematical model is used to mimic the real machine in simulations with the purpose of analyzing the interaction between structural dynamics and a high bandwidth adaptive sliding mode controller. Meanwhile, efficiency of finite element modeling approaches in predicting this interaction prior to the physical production is investigated by replacing the machine dynamics by a FEM based model. The mathematical model is used to design a Kalman Filter which estimates the table's acceleration by taking double digital derivative of the encoder signal. The table's acceleration is used to modify the control loop to minimize the effect of undesired structural vibrations. It is shown that the vibrations can be actively damped, and the bandwidth of the drive can be increased. The increase in the servo loop bandwidth provides smoother motion and improves the tracking performance significantly.

description: In this paper we propose a simple approach to asset valuation in terms of two characteristics, expected value and expected variability, and their distinct marginal contributions to the value of the market portfolio. The result is shown to correspond to Sharpe’s CAPM. We then show that pricing in terms of characteristics (or CAPM) applies to any asset and in particular to option valuation. A pricing formula corresponding to Black and Scholes’ no-arbitrage option pricing is obtained under the assumption of normal asset price distributions.

description: We test the "induced demand" model on cesarean section, relying on a natural experiment of proportional fee reduction of all delivery procedures. This fee change does not imply any substitution effect and allows a proper measure of the income effect. We extend the demand induction model and derive its testable implications by introducing a discrete class of patients towards which physicians can discriminate their inducement behaviour. The empirical test is performed estimating a simultaneous binary probit model in which the probability of c-section delivery depends on the type of hospital chosen and the latter is allowed to be endogenously determined.

description: We derive quantitative error estimates for coupled reaction-diffusion systems, whose coefficient functions are quasi-periodically oscillating modeling microstructure of the underlying macroscopic domain. The coupling arises via nonlinear reaction terms, and we allow for different diffusion length scales, i.e. whereas some species have characteristic diffusion length of order 1, other species may diffuse much slower, namely, with order of the characteristic microstructure-length scale. We consider an effective system, which is rigorously obtained via two-scale convergence, and we derive quantitative error estimates.

description: This note deals with the analysis of a model for partial damage, where the rate-independent, unidirectional flow rule for the damage variable is coupled with the rate-dependent heat equation, and with the momentum balance featuring inertia and viscosity according to Kelvin-Voigt rheology. The results presented here combine the approach from  [Roubiček M2AS'09, SIAM'10] with the methods from Lazzaroni/Rossi/Thomas/Toader [WIAS Preprint 2025]. The present analysis encompasses, differently from [Roubiček SIAM'10], the monotonicity in time of damage and the dependence of the viscous tensor on damage and temperature, and, unlike [WIAS Preprint 2025], a nonconstant heat capacity and a time-dependent Dirichlet loading.
La "mentalità industriale" di Angelo Marescotti

description: Il lavoro illustra il pensiero dell’economista romagnolo Angelo Marescotti (1815-1892) relativo al processo di sviluppo delle industrie italiane e propone una rilettura delle tesi di Marescotti sull’innovazione e sul processo concorrenziale. Dall’analisi dei suoi testi emerge la proposta di una strategia di industrializzazione basata esclusivamente sui meccanismi di mercato che rappresentava una posizione minoritaria nel panorama delle teorie economiche nell’Italia della seconda metà dell’Ottocento.
Evaluating Monetary Policy Regimes: The Role of Nominal Rigidities

Subjects: SECS-P/01 Economia politica

description: I compare four basic monetary policy rules belonging to the interest-rate pegging rules class in two different analystical frameworks representing the way through which nominal rigidities are designed. A first model consider the Calvo-Woodford mechanism of price adjustment, as has become customary in the literature on monetary policy rules. A second model, instead, considers the cost of price adjustment function, as proposed by Rotemberg (1982). The two models are simulated to find the optimal monetary policy rule, maximizing the welfare of the representative agent. The results show that the optimal monetary policy rule for the model based on the Calvo price setting method is a simple contemporaneous interest-pegging rule with a lagged nominal interest rate. However, with a model based on the cost of price adjustment, the optimal rule is given by an interest rate rule with a expected inflation, contemporaneous output gap and a lagged interes rate term as arguments. Impulse respnse functions for different vallues of the parameters of the respective optimal monetary poliy function are plotted for both models, for an expansionary public expenditure shock and a contractionary monetary policy shock. The calculation of the model are empirically robust. For the first time fiscal policy is explicitly inserted in the model through a ’Passive’ tax policy rule. An explicit analysi f about the determinacy of the equilibrium is contained in the model.

description: We present a randomized iterative algorithm that exponentially converges in expectation to the minimum Euclidean norm least squares solution of a given linear system of equations. The expected number of arithmetic operations required to obtain an estimate of given accuracy is proportional to the square condition number of the system multiplied by the number of non-zeros entries of the input matrix. The proposed algorithm is an extension of the randomized Kaczmarz method that was analyzed by Strohmer and Vershynin.

description: The Uniform California Earthquake Rupture Forecast version 3-Time Dependent is a complex
mathematical model of where California’s seismic faults are and how frequently they produce
earthquakes. The model is represented by a logic tree with 5,760 leaves, each representing one
combination of modeling choices to represent epistemic uncertainties. To use the model in risk
analysis, one must often add epistemic uncertainties, such as which of several ground-motionprediction
equations to use. Doing so can increase the model size to 172,800 leaves. Each leaf still
has explicit uncertainties, often called aleatory uncertainties, such as whether each of 6 million
possible earthquakes will occur and the resulting map of spatially correlated shaking. To use the
model in practice with all these uncertainties can be computationally demanding. It is desirable to
find a subset of epistemic uncertainties that preserve the distribution of important dependent
variables. We previously showed how to trim the logic tree to preserve the distribution of expected
annualized repair cost to a large portfolio of California buildings. Here we show how to trim the
logic tree to preserve the distributions of expected annualized repair cost and of loss with various
rare exceedance frequencies: 1 time in 100 years, 250 years, 400 years, 550 years, and 2,500 years.
It appears that one can reduce the logic tree to as few as 15 logic tree leaves (from 172,800),
varying only ground motion model and ground motion model added epistemic uncertainty, at least
for the 400-year and 550-year losses. A hypothetical risk calculation that takes 24 hours for the
full model (evaluating all 172,800 leaves) can be reduced to a calculation that takes 8 seconds (for
a reduced-order model with 15 leaves). But in all cases examined here, one can trim the logic tree
by at least three variables. Because of the exponential relationship between the number of logic
tree branches and the size of the model, even trimming three variables can produce a huge savings
in computational effort, reducing the number of logic tree leaves to 4% of the size of the full model.
Model order reduction can have important financial benefits. With more study, it may be possible
to reduce uncertainty around the choice of ground motion model and of added epistemic
uncertainty in the ground motion model. Lower uncertainty means thinner tails to the distribution
of loss, that is, lower loss associated with rare exceedance rates. If an insurer can reduce its
estimate of rare loss, it can buy less reinsurance and save money.
