Regional left ventricular systolic pressure-thickness relations have been used to assess regional load-insensitive contractility with the assumption that they possess linear isochrones that are fundamental to the time-varying elastance model of global pressure-volume relations. We examined the shape and time-varying behavior of pressure-thickness isochrones in six open-chest canine preparations. Transmural wall thickening (sonomicrometry) and ventricular pressure were altered by abrupt preload alterations during control, dobutamine, and propranolol. In all dogs and interventions, linear isochrones (r2 mean +/- SE = 0.91 +/- 0.11) were found at 5-ms intervals. During control, linear isochrone slope rose monotonically from onset to end of systole. Thickness-axis intercepts also varied continuously in time, but peak intercept and maximal slope were asynchronous. Dobutamine caused a steeper earlier maximum slope and increased slope-intercept asynchrony. Propranolol reduced maximum slope and slope-intercept asynchrony. Isochronal data during early systole were better fitted to a parabolic than to the linear model; however, fits to linear and parabolic models were equally good near end of systole. Linear isochronal behavior exists in systolic pressure-thickness relations especially near end systole and is maintained during modest inotropic alterations.

Abstract This study addresses observational and modeling sensitivity on the march of the onset isochrones of the Indian summer monsoon. The first 25 days of the passage of the isochrones of monsoon onset is of great scientific interest. Surface and satellite-based datasets are used for high-resolution modeling of the impact of the motion of the onset isochrones from Kerala to New Delhi. These include the asymmetries across the isochrone such as soil moisture and its temporal variability, moistening of the dry soil to the immediate north of the isochrone by nonconvective anvil rains, and formation of newly forming cloud elements to the immediate north of the isochrone. The region immediately north of the isochrone is shown to carry a spread of buoyancy elements. As these new elements grow, they are continually being steered by the divergent circulations of the parent isochrone to the north and eventually to the northwest. CloudSat was extremely useful for identifying the asymmetric cloud structures across the isochrone. In the modeling sensitivity studies, the authors used a mesoscale Advanced Research Weather Research and Forecasting Model (ARW-WRF) to examine days 1–25 of forecasts of the onset isochrone. Prediction experiments were first modeled during normal, dry, and wet Indian monsoons using default values of model parameters. This study was extended to determine the effects of changes in soil moisture and nonconvective rain parameterizations (the parameters suggested by the satellite observations). These sensitivity experiments show that the motion of the isochrones from Kerala to New Delhi are very sensitive to the parameterization of soil moisture and nonconvective anvil rains immediately north of the isochrone.

Résumé L’objectif principal de cette étude pilote est de tester expérimentalement ce que nous appelons l’Hypothèse d’Isochronie Syllabique Initiale. Selon cette hypothèse, les apprenants de L2 passent par une phase initiale pendant laquelle leurs productions orales présentent les caractéristiques rythmiques des langues dites à isochronie syllabique (telles que l’espagnol et le français). Pour cela, nous analysons des récits oraux d’apprenantes débutantes de français ayant le suédois pour langue maternelle (n = 6). Ces productions sont comparées à celles d’un groupe de locutrices natives du français (n = 6) et d’un groupe de locutrices natives du suédois (n = 6). Les caractéristiques rythmiques des récits en français L2, français L1 et suédois L1 sont étudiées à partir de deux mesures acoustiques, notamment le coefficient de variation de la durée syllabique, dont l’utilisation est préconisée par Patel (2008) pour déterminer si une langue est de type accentuel ou syllabique. Les mesures acoustiques employées permettent de confirmer que le français et le suédois appartiennent à des familles rythmiques distinctes. Les résultats de l’étude vont cependant à l’encontre de l’Hypothèse d’Isochronie Syllabique Initiale.

AbstractFor an attracting periodic orbit (limit cycle) of a deterministic dynamical system, one defines the isochron for each point of the orbit as the cross-section with fixed return time under the flow. Equivalently, isochrons can be characterized as stable manifolds foliating neighborhoods of the limit cycle or as level sets of an isochron map. In recent years, there has been a lively discussion in the mathematical physics community on how to define isochrons for stochastic oscillations, i.e. limit cycles or heteroclinic cycles exposed to stochastic noise. The main discussion has concerned an approach finding stochastic isochrons as sections of equal expected return times versus the idea of considering eigenfunctions of the backward Kolmogorov operator. We discuss the problem in the framework of random dynamical systems and introduce a new rigorous definition of stochastic isochrons as random stable manifolds for random periodic solutions with noise-dependent period. This allows us to establish a random version of isochron maps whose level sets coincide with the random stable manifolds. Finally, we discuss links between the random dynamical systems interpretation and the equal expected return time approach via averaged quantities.

AbstractWe use simple numerical and analytical models of ice flow and heat flow to characterize the shape of isochrones and isotherms beneath moving ice divides. Both nonlinear ice flow and reduced accumulation (wind scouring) at a divide can cause reduced downward flow in a region about one ice thickness wide under a divide. Greater downward velocities on the flanks cause isochrones and isotherms to become arched at depth. The magnitudes and shapes of these arches depend on the history of divide position. Arch amplitudes decrease by approximately e−1 for each increase in migration rate of 3–5 times the accumulation rate, the arches become asymmetric, with steeper leading edges and more gentle trailing edges, and the arch apex lags behind the divide. Isochrone and isotherm shapes can be used to infer past divide motions. In advection-dominated ice sheets, isochrone shapes record a longer history of divide position than do isotherm shapes. The opposite is true for diffusion-dominated ice sheets, in which a spatial array of ice-temperature measurements might extend the recorded history of divide position.

AbstractIn this paper, we study the local bifurcations of critical periods in the neighborhood of a nondegenerate centre of the reduced Kukles system. We find at the same time the isochronous systems. We show that at most three local critical periods bifurcate from the Christopher-Lloyd centres of finite order, at most two from the linear isochrone and at most one critical period from the nonlinear isochrone. Moreover, in all cases, there exist perturbations which lead to the maximum number of critical periods. We determine the isochrones, using the method of Darboux: the linearizing transformation of an isochrone is derived from the expression of the first integral. Our approach is a combination of computational algebraic techniques (Gröbner bases, theory of the resultant, Sturm’s algorithm), the theory of ideals of noetherian rings and the transversality theory of algebraic curves.

Abstract. Conventional Re–Os isochrons are based on mass spectrometric estimates of 187Re/188Os and 187Os/188Os, which often exhibit strong error correlations that may obscure potentially important geological complexity. Using an approach that is widely accepted in 40Ar/39Ar and U–Pb geochronology, we here show that these error correlations are greatly reduced by applying a simple change of variables, using 187Os as a common denominator. Plotting 188Os/187Os vs. 187Re/187Os produces an “inverse isochron”, defining a binary mixing line between an inherited Os component whose 188Os/187Os ratio is given by the vertical intercept, and the radiogenic 187Re/187Os ratio, which corresponds to the horizontal intercept. Inverse isochrons facilitate the identification of outliers and other sources of data dispersion. They can also be applied to other geochronometers such as the K–Ca method and (with less dramatic results) the Rb–Sr, Sm–Nd and Lu–Hf methods. Conventional and inverse isochron ages are similar for precise datasets but may significantly diverge for imprecise ones. A semi-synthetic data simulation indicates that, in the latter case, the inverse isochron age is more accurate. The generalised inverse isochron method has been added to the IsoplotR toolbox for geochronology, which automatically converts conventional isochron ratios into inverse ratios, and vice versa.

In this paper, we study an excitable and nonoscillating neuron on the basis of a technique of extending the concept of isochrons from oscillatory to excitable systems. The extended isochrons allow reduction of an excitable system described by possibly high dimensional differential equations to a simpler system. We analytically derive a one-dimensional model of an excitable neuron stimulated by instantaneous pulses with the technique of the extended isochrons and show its similarity to an isochronal map numerically obtained from the FitzHugh–Nagumo model. Response characteristics of the one-dimensional model to periodic impulsive stimulations are also analyzed numerically.

In the Czech Republic, there is currently no objective method to diagnose graphomotor difficulties in children. Ongoing research uses modern digitizers to capture the hand-writing process and quantify its parameters. The first goal of this thesis is to develop software tools to faciliate work with the collected data, such as database validation and writing exercise rating, done by specialists. Another goal of this thesis is to design new on-line handwriting parameters which are then to be analysed on a cohort of school children from 2nd to 4th class of primary school (n=239). The implementation of two desktop programs on the .NET platform is described, among three new quantifying parameters based on the principles of isochrony, two-dimensional cross-correlation, and geometrical centroid. All three parameters show significant correlation (r = [0,2; 0,3])with the HPSQ-C rating in 2nd- and 4th-graders and correlation (đťśŚ= [0,2; 0,5]) with specialistâ€™s subjective scores in all children from the cohort. The analysis suggests children with graphomotor difficulties struggle with regulating handwriting speed and working memory.

Depuis la stagnation de la fréquence d’horloge des processeurs, l’accroissement de la puissance de calcul a dépendu entièrement de l’accroissement du nombre d’unités de calcul. Plus que la difficulté algorithmique impliquée par l’écriture de tout programme séquentiel, la programmation parallèle demande au programmeur de gérer de nombreuses unités de calcul, incluant leurs tâches et leurs interactions. Pour alléger le fardeau du programmeur, cette thèse propose deux approches différentes de génération automatique de code parallèle. Le modèle parallèle isochrone BSP possède des propriétés intéressantes telles que son modèle de coût qui en font la cible de notre génération de code parallèle. Les automates et expressions régulières sont souvent choisis pour modéliser les calculs séquentiels et leurs parallélisation devrait, à long terme, aboutir à de solides fondations pour la génération de code parallèle. Pour notre approche principale, nous développons la théorie des automates BSP avec leur génération et détermination. Cette théorie est utilisée dans une nouvelle méthode pour la recherche de motif à l’aide d’expressions régulières. Notre autre approche propose un langage spécifique au domaine des réseaux de neurones où la composition fonctionnelle d’un petit nombre de primitives facilite le développement, la maintenance et la définition formelle du langage par rapport aux approches existantes
Since we are in an era of processor clock stagnation, computing power growth has been relying on parallel computing. More than the algorithmic difficulty involved in any program writing, parallel computing additionally requires the programmer to manage numerous processing units including their tasks and interactions. In order to alleviate the parallel programmer’s burden, this thesis proposes two different approaches for automatic parallel code generation. The bulk-synchronous parallel (BSP) model provides good properties such as its cost model and is therefore chosen as the target of our parallel code generation.Automata and regular expressions are often chosen to model sequential computation and their parallelization will lead to a strong foundation for general parallel code generation. For our main approach, we develop the theory of BSP automata with their generation and determinization. This theory is used in a novel method for parallel regular expression matching.As another approach, we propose a domain specific language for programming neural nets where the functional composition of only a few primitives eases development, maintenance and formal definition of the language compared to existing approaches

AN ABSTRACT OF THE THESIS OF José E. Guzmán Borrero, for the Master of Music degree in Music Theory and Composition, presented on April 8, 2016, at Southern Illinois University Carbondale. TITLE: ISOCHRONAL: A SUITE FOR JAZZ ORCHESTRA MAJOR PROFESSOR: Dr. Christopher Walczak The suite is a three movement composition for jazz orchestra in which I integrate contemporary compositional methods with the harmonic idioms of the jazz genre. The first movement, “Flight,” takes a minimalist (ca. 1970-1990) approach through the beginning of the piece, then incorporates a development section reminiscent of music from the Classical period with the use of two and three voice counterpoint. Followed by a traditional jazz solo section. The second movement, “'Round Ten” is a ballad featuring the post-tonal compositional method of dodecaphony (ca. 1925-1950) in tandem with melodic and harmonic jazz expressions reminiscent of Thelonious Monk. My compositional use of tone rows is similar to the methods of Benjamin Britten and Alban Berg, who used the row as a compositional guideline or tool. This is unlike the initial use of the row by its founder, Arnold Schoenberg, which restricted the composer by the necessity of using all twelve pitches (with no emphasis on a tonal center) and using it in a predetermined order. The ballad section of the second movement is similar to Thelonious Monk's music in its use of non-harmonic tones and sharp dissonances mixed with a repetitive melodic contour. The third and final movement, “Lights Out!” is an up-tempo piece that uses the dense harmonies reminiscent of Don Menza and Thad Jones’ arrangements. The harmonic structure of the piece is from the modal jazz period of the 1960s in which composers pushed the boundaries of the typical 32-bar song format. The melodic material in this movement includes material from the two previous movements.

On calcule explicitement les premiers coefficients de la forme normale d'un champ de vecteurs hamiltonien polynomial homogene, et un debut d'etude des champs hamiltoniens non homogenes est entreprise, au sens ou, la aussi, on calcule completement les premiers coefficients des formes normales mises en jeu. Notre travail permet d'attacher des invariants algebriques aux champs de vecteurs, et donc d'ebaucher une classification de ces champs. De plus, les equations algebriques provenant des ces invariants completement explicites dans certains cas, en particulier pour le cas hamiltonien, permettent de generer des conditions pour la linearisation des champs polynomiaux au voisinage de l'origine, qui est un point critique de type elliptique. Le probleme de la linearisation, ou encore du probleme du centre, est ainsi aborde par le biais des varietes algebriques definies par les equations associees aux champs de vecteurs etudies.

Rapid and robust characterization of large earthquakes in terms of their spatial extent and temporal duration is of high importance for disaster mitigation and early warning applications. Backtracking of seismic P-waves was successfully used by several authors to image the rupture process of the great Sumatra earthquake (26.12.2004) using short period and broadband arrays. We follow here an approach of Walker et al. to backtrack and stack broadband waveforms from global network stations using traveltimes for a global Earth model to obtain the overall spatio-temporal development of the energy radiation of large earthquakes in a quick and robust way. We present results for selected events with well studied source processes (Kokoxili 14.11.2001, Tokachi-Oki 25.09.2003, Nias 28.03.2005). Further, we apply the technique in a semi-real time fashion to broadband data of earthquakes with a broadband magnitude >= 7 (roughly corresponding to Mw 6.5). Processing is based on first automatic detection messages from the GEOFON extended virtual network (GEVN).

This work aims to contribute to the solution of a problem relevant to archaeology and microdosimetry, namely the TL dating of destratified archaeological ceramics. It is apparent that museums hold a large body of archaeological material excavated from important sites during the early part of this century. Absolute dating of this corpus of material would be extremely valuable to archaeology in allowing historic hypotheses to be tested. The background to this problem has been presented within the context of the historical development of thermoluminescence dating and of dosimetry concepts. A critical review of previously proposed strategies for dating material from unknown gamma contexts is presented, and then a general model using an isochron approach is introduced. The isochron model is then developed explicitly and theoretical simulation is used to explore different microdosimetric systems. Two main isochron solutions have been identified, the grain size (or alpha-beta attenuation) and alpha efficiency isochrons. An experimental approach was designed, to evaluate the validity of the grain size isochron predictions, using model matrices. Isochron behaviour was clearly observed in both cases. The first system, based on microcline feldspar grains in a high dose rate matrix, produced an age estimate consistent with the known age. The second experiment, using fluorite grains in a lower dose rate matrix, produced a highly coherent data set. However, the age estimate obtained was greater than the expected value by a factor of approximately 3. The possible reasons for this are discussed in detail. A brief experiment carried out subsequently on duplicate portion of this matrix gave results that are consistent with predicted values. Thus, it would appear that the original experimental design and method were valid and that the isochron approach does indeed deserve further investigation.

The open cluster Messier 67 is known to have chemical composition, metallicity and age (~ 4 Gyr) close to the Sun. Therefore, it is advantageous for stellar physical studies and of stellar evolution, in particular for solar like stars within the cluster. This work considers three such stars, the formerly studied solar twin M67-1194 and two more recently suggested solar twins M67-1787 & 2018. Most solar twins show a ratio of volatile to refractory elements that systematically depart from the Sun’s. Our targets do not follow this trend as closely. Their composition is closer to the Sun and they are, therefore, exquisite targets for studies of stellar evolution within the cluster. However, their solar likeness also provides studies regarding the origin and evolution of the Solar system. The stellar ages of the solar twins are established through a chemical clock [Y/Mg] and via stellar isochrones from BaSTI. The latter age assessment of the solar twins is supplemented with the analysis of two subgiant stars M67-1442 & 1844. We approach the isochrone-based method using spectroscopically, astrometrically and photometrically derived parameters. The different ages of the stars and methods thus estimate the age of the cluster itself. The chemical ages of the stars suggest a cluster age of 4.56 ±0.44 Gyr and the isochrone-based estimates suggests a cluster age within the range 3.30-5.51 Gyr. Our results thus affirm and imply a near solar age of the cluster.

A sincronização estável de redes tem papel central em diversos fenômenos de interesse científico, e.g., arritmias cardíacas, crises epiléticas e o desempenho de atos cognitivos no cérebro. Assim, a estabilidade da sincronização e as condições que levam às fronteiras de instabilidade são tópicos de interesse científico considerável. Entretanto, no que diz respeito à sincronização isócrona (com atraso zero), a literatura está desprovida de ferramentas gerais e analíticas para estudar e determinar a estabilidade da sincronização. Enfoques existentes não fornecem metodologias gerais e, além disso, fazem uso de hipóteses improváveis do ponto de vista prático. Considerando o teorema de Lyapunov-Krasovskii, o problema da estabilidade da sincronização isócrona é formulado e resolvido de forma a propor alternativas para eliminar essas hipóteses restritivas. A solução consiste em expressões analíticas que revelam a dependência da estabilidade da sincronização em relação aos parâmetros da rede. Como resultado, um conjunto de ferramentas é introduzido para explorar a estabilidade da sincronização isócrona em redes complexas de osciladores caóticos com atraso de acoplamento. Para avaliar o conservadorismo dos resultados e para aumentar o escopo dos resultados, simulações numéricas são realizadas e avaliadas. Finalmente, é apresentada a aplicação da sincronização isócrona em comunicação baseada em caos e TDMA, que emprega a sincronização para estabelecer comunicação coordenada entre os nós de redes de osciladores.

All isotopes heavier than 208Pb (lead) are radioactive and many of these have half-lives that are long compared to the age of our Solar System. ‘Uranium, thorium, and their daughters’ describes the natural decay series where radioactive isotopes of uranium and thorium decay by α- and β-emission through several stages until a stable lead isotope is produced. The age of the Solar System and Earth has been established at 4.55 Ga through the isochron approach; U-Pb dating was also used to date the boundary between the Cretaceous and Palaeogene geological periods to 66 Ma, the period associated with a mass extinction on Earth when 70 per cent of living things died out.
