description: In this paper we prove an approximation result for the viscosity solution of a system of semi-linear partial differential equations with continuous coefficients and nonlinear Neumann boundary condition. The approximation we use is based on a penalization method and our approach is probabilistic. We prove the weak uniqueness of the solution for the reflected stochastic differential equation and we approximate it (in law) by a sequence of solutions of stochastic differential equations with penalized terms. Using then a suitable generalized backward stochastic differential equation and the uniqueness of the reflected stochastic differential equation, we prove the existence of a continuous function, given by a probabilistic representation, which is a viscosity solution of the considered partial differential equation. In addition, this solution is approximated by solutions of penalized partial differential equations.

description: We introduce the Mechanic, a new open-source code framework. It is designed to reduce the development effort of scientific applications by providing unified API (Application Programming Interface) for configuration, data storage and task management. The communication layer is based on the well-established Message Passing Interface (MPI) standard, which is widely used on variety of parallel computers and CPU-clusters. The data storage is performed within the Hierarchical Data Format (HDF5). The design of the code follows em core-module approach which allows to reduce the user's codebase and makes it portable for single- and multi-CPU environments. The framework may be used in a local user's environment, without administrative access to the cluster, under the PBS or Slurm job schedulers. It may become a helper tool for a wide range of astronomical applications, particularly focused on processing large data sets, such as dynamical studies of long-term orbital evolution of planetary systems with Monte Carlo methods, dynamical maps or evolutionary algorithms. It has been already applied in numerical experiments conducted for Kepler-11 (Migaszewski et al., 2012), and nuOctantis planetary systems (Goździewski et al., 2013). In this paper we describe the basics of the framework, including code listings for the implementation of a sample user's module. The code is illustrated on a model Hamiltonian introduced by (Froeschle et al., 2000) presenting the Arnold diffusion. The Arnold Web is shown with the help of the MEGNO (Mean Exponential Growth of Nearby Orbits) fast indicator (Goździewski et al., 2008a) applied onto symplectic SABA integrators family (Laskar and Robutel, 2001).

description: This paper presents an approach to the modeling of degree-degree correlation in complex networks. Thus, a simple function, Δ(k', k), describing specific degree-to- degree correlations is considered. The function is well suited to graphically depict assortative and disassortative variations within networks. To quantify degree correlation variations, the joint probability distribution between nodes with arbitrary degrees, P(k', k), is used. Introduction of the end-degree probability function as a basic variable allows using group theory to derive mathematical models for P(k', k). In this form, an expression, representing a family of seven models, is constructed with the needed normalization conditions. Applied to Δ(k', k), this expression predicts a nonuniform distribution of degree correlation in networks, organized in two assortative and two disassortative zones. This structure is actually observed in a set of four modeled, technological, social, and biological networks. A regression study performed on 15 actual networks shows that the model describes quantitatively degree-degree correlation variations.

description: Through painting, I rely on non-visual sensory information recorded in the woods to inform aesthetic decisions. Research happens in the act of painting. All visual and written references inform the collection of source material, but research happens during the translation between lived experience and paint. When painting reveals meaning, looking at other artists paintings or subsequent readings about recently discovered themes can supplement the research and direct a new path of painted investigation, but can never replace painting. This document is a descriptive account of how my cognitive system translates sensorial energy observed in the woods into painting. In place of a table of contents, the adjacent map serves as a visual guide through the document with the three main headers becoming structural sections: Brain (pg. 04) ; Woods (pg. 14) ; Material (pg. 24). The rooted nature of this map better reflects the non-linear progression of thinking through painting utilized in my practice. Fictional and poetic references are included in this document with only an accompanying painting for context. These references have tangentially informed the production of paintings and are isolated for further interpretation and reflection alongside a finished painting.
Bayesian Analysis of ODE's: solver optimal accuracy and Bayes factors

description: In most relevant cases in the Bayesian analysis of ODE inverse problems, a numerical solver needs to be used. Therefore, we cannot work with the exact theoretical posterior distribution but only with an approximate posterior deriving from the error in the numerical solver. To compare a numerical and the theoretical posterior distributions we propose to use Bayes Factors (BF), considering both of them as models for the data at hand. We prove that the theoretical vs a numerical posterior BF tends to 1, in the same order (of the step size used) as the numerical forward map solver does. For higher order solvers (eg. Runge-Kutta) the Bayes Factor is already nearly 1 for step sizes that would take far less computational effort. Considerable CPU time may be saved by using coarser solvers that nevertheless produce practically error free posteriors. Two examples are presented where nearly 90% CPU time is saved while all inference results are identical to using a solver with a much finer time step.

description: A prefix normal word is a binary word with the property that no substring has more 1s than the prefix of the same length. This class of words is important in the context of binary jumbled pattern matching. In this paper we present an efficient algorithm for exhaustively listing the prefix normal words with a fixed length. The algorithm is based on the fact that the language of prefix normal words is a bubble language, a class of binary languages with the property that, for any word w in the language, exchanging the first occurrence of 01 by 10 in w results in another word in the language. We prove that each prefix normal word is produced in O(n) amortized time, and conjecture, based on experimental evidence, that the true amortized running time is O(polylog(n)).

description: Drifts in the Parker spiral interplanetary magnetic field are known to be an important component in the propagation of galactic cosmic rays, while they are thought to be negligible for Solar Energetic Particles (SEPs). As a result they have so far been ignored in SEP propagation modelling and data analysis. We examine drift velocities in the Parker spiral within single particle first-order adiabatic theory, in a local coordinate system with an axis parallel to the magnetic field. We show that, in the presence of scattering in interplanetary space, protons at the high end of the SEP energy range experience significant gradient and curvature drift. In the scatter-free case, drift due to magnetic field curvature is present. The magnitude of drift velocity increases by more than an order of magnitude at high heliographic latitudes compared to near the ecliptic; it has a strong dependence on radial distance r from the Sun, reaching a maximum at r~1 AU at low heliolatitudes and r~10 AU at high heliolatitudes. Due to the mass over charge dependence of drift velocities, the effect of drift for partially ionised SEP heavy ions is stronger than for protons. Drift is therefore likely to be a considerable source of cross field transport for high energy SEPs.

description: We investigate the evolution of the star formation rate (SFR)-density relation in the Extended Chandra Deep Field South (ECDFS) and the Great Observatories Origin Deep Survey (GOODS) fields up to z~1.6. In addition to the "traditional method", in which the environment is defined according to a statistical measurement of the local galaxy density, we use a "dynamical" approach, where galaxies are classified according to three different environment regimes: group, "filament-like", and field. Both methods show no evidence of a SFR-density reversal. Moreover, group galaxies show a mean SFR lower than other environments up to z~1, while at earlier epochs group and field galaxies exhibit consistent levels of star formation (SF) activity. We find that processes related to a massive dark matter halo must be dominant in the suppression of the SF below z~1, with respect to purely density-related processes. We confirm this finding by studying the distribution of galaxies in different environments with respect to the so-called Main Sequence (MS) of star-forming galaxies. Galaxies in both group and "filament-like" environments preferentially lie below the MS up to z~1, with group galaxies exhibiting lower levels of star-forming activity at a given mass. At z>1, the star-forming galaxies in groups reside on the MS. Groups exhibit the highest fraction of quiescent galaxies up to z~1, after which group, "filament-like", and field environments have a similar mix of galaxy types. We conclude that groups are the most efficient locus for star-formation quenching. Thus, a fundamental difference exists between bound and unbound objects, or between dark matter haloes of different masses.

description: "Perhaps no idea is more fundamental to the establishment of the United States. But more than 200 years after the gathering at Boston Harbor, the 600,000 residents of the District of Columbia embody precisely the wrongs Americans fought the Revolutionary War to eradicate.
For three years, Norton has served as a delegate to the House of Representatives for the District of Columbia. As delegate she has the same powers as any other Representative to Congress to serve on and chair Committees, introduce legislation, and participate in floor debates. Unlike full Representatives; however, she is denied the right to vote on final passage and some floor amendments. Even this restricted representation is denied DC's shadow Senators in the Senate.
While on Capitol Hill, Congresswoman Norton has dedicated herself to what a fellow democrat called "an uphill battle through molasses in a blizzard." Norton wants to add one more star to the American flag-a 51st for the District of Columbia. And in a historic vote last November, Rep. Norton was able to muster 153 votes for statehood, not enough to pass the resolution, but far more than even her most ardent supporters had expected. The final tally on H.R. 51, the statehood resolution, was 277 nays, 153 ayes. But for Rep. Norton, success came two days earlier when the bill finally reached the floor of the House of Representatives. Norton is glad that

description: We compute the Hamiltonian and Lagrangian associated to the large deviations of the trajectory of the empirical distribution for independent Markov processes, and of the empirical measure for translation invariant interacting Markov processes. We treat both the case of jump processes (continuous-time Markov chains and interacting particle systems) as well as diffusion processes. For diffusion processes, the Lagrangian is a quadratic form of the deviation of the trajectory from the Kolmogorov forward equation. In all cases, the Lagrangian can be interpreted as a relative entropy or relative entropy density per unit time.

description: Many molecules exhibit multiple conformers that often easily interconvert under thermal conditions. Therefore, single conformations are difficult to isolate which renders the study of their distinct chemical reactivities challenging. We have recently reported a new experimental method for the characterization of conformer-specific effects in chemical reactions [Y. P. Chang et al., Science 342, 98 (2013)]. Different conformers are spatially separated using inhomogeneous electric fields and reacted with a Coulomb crystal of cold, spatially localized ions in a trap. As a first application, we studied reactions between the two conformers of 3-aminophenol and Ca$^+$. We observed a twofold larger rate constant for the $cis$ compared to the $trans$ conformer which was rationalized in terms of the differences in the long-range ion-molecule interactions. The present article provides a detailed description of the new method and a full account of the experimental results as well as the accompanying theoretical calculations.

description: The present proliferation of e-learning has been actively underway for the last 10 years. Current research in Adaptive Testing System focuses on the development of psychometric models with items selection strategies applicable to adaptive testing processes. The key aspect of proposed Adaptive Testing System is to develop an increasingly sophisticated latent trait model which can assist users in developing and enhancing their skills. Computerized Adaptive Test (CAT) System requires a lot of investment in time and effort to develop analyze and administrate an adaptive test. In this paper a fuzzy logic based Multi User Adaptive Test System (MUATS) is developed. Which is a Short Messaging Service (SMS) based System, currently integrated with GSM network based on the new psychometric model in education assessment. MUATS is not only a platform independent Adaptive Test System but also it eases the evaluation effort for adaptive test process. It further uses fuzzy logic to pick the most appropriate question from the pool of database for a specific user to be asked which makes the overall system an intelligent one.

description: This tool is a set of phantom-based test methods for objective, quantitative evaluation of fluorescence imaging system performance. Tests for key image quality characteristics are presented based on simple fluorescence-dye-doped targets and turbid phantoms based on epoxy with scattering dopants. Additionally, the penetration depth phantom was fabricated using photopolymer resins in a 3D printer. The test characteristics include spatial resolution, uniformity, sensitivity, linearity, field of view, depth of field, spectral crosstalk, and penetration depth. Basic optical properties were validated with spectrophotometry. The test methods have been implemented as a demonstration of how this tool can be used to characterize the performance of a custom benchtop near-infrared fluorescence imaging system. Further information is provided in the journal article: Performance test methods for near-infrared fluorescence imaging.

description: В статье рассматривается исследование и оценка хаотической динамики пара-метров сложных нестационарных биосистем, в частности особый тип хаоса, возникающий в параметрах, которыми эти системы описаны. В отличие от детерминированного хаоса Лоренса, в таких системах не только невоспроизводим процесс, но и никогда невоспроизводимо начальное состояние системы. В основе исследования лежит оценка степени хаотичности временных рядов кардиосигналов сердечно-сосудистой системы человека с использованием методов непараметрической математической статистики, методов нелинейной динамики. При помощи автокорреляционного анализа на примере элементов кардиосигналов (временных рядов кардиоинтервалов) сердечно-сосудистой системы показано, что параметры биосистем имеют строго хаотическую структуру и нелинейную тенденцию. Расчет старшего показателя Ляпунова показал, что происходит постоянная смена знака (+, −) при каждой регистрации кардиосигналов, что доказывает наличие хаотических процессов в работе сердца. Исследование может быть использовано для идентификации параметров функционального состояния организма человека.
description: The article studies and evaluates the chaotic dynamics parameters of complex nonstationary biosystems, in particular, a specific chaos type occurring in the parameters that describe the systems mentioned. Contrary to Lawrence deterministic chaos, these systems provide neither the process of repetition nor the repetition of the system’s initial state. The study is based on the evaluation of the degree of chaotic time series of cardiac signals of a human cardiovascular system using methods of non-parametric mathematical statistics and those of non-linear dynamics. On the example of elements of cardiac signals (time series cardiac intervals) of a cardiovascular system and with autocorrelation analysis, the study shows that biosystem parameters have a strictly chaotic structure and non-linear trend. The chaotic processes in cardiac performance are demonstrated by computing the largest Lyapunov exponent and, as a result, a constant sign (+, −) change in each cardiac signal recording. The study can be used to identify parameters of the functional state of a human organism.

description: This paper is in support of the artwork created during the MFA program at Emily Carr University of Art and Design and as such will be focusing on encounters with ‘strangers’ through the ‘act of photography’. This essay will discuss the notion of the ‘stranger’ in relation to staged ‘photographic acts’, that attempt to trouble the boundary between the ‘public’ and ‘private’. I offer a brief outline of the notion of the ‘public’ and ‘private’ by citing authors such as Hannah Arendt and Kio Stark, who question the history and its modern understanding of these two social spheres through their analysis of social behaviour. Social contracts, the unspoken and unwritten rules informing our everyday interactions in the public, will be challenged through photographic interventions that expose social conventions and expected behaviour, in relation to the ‘stranger’. Through the use of the camera, as well as the use of self-imposed rules, I outline how the ‘act of photography’ can play with the performed norms and interpersonal relationships in the public space. My aim is to both disrupt and reveal -- i.e. ‘make visible’ -- these normative practices of public behaviour. Importantly too, my aim is to reveal the subject’s vulnerability. Vulnerability plays a central role in my practice, and acts as a way to penetrate the boundary people build around themselves in public situations. That is, their ‘masks’ or ‘public face’, so to speak. The aim of my research is to trouble the hidden social contracts that determine normative social behaviour in the public space and make them visible within the photograph, either through portraits that take on the form of still photographs or video. This essay will discuss the trajectory of my projects, alongside artists and theorists, while highlighting the use of photography and portraiture as central to my practice.
Revealing the evolution, the stability and the escapes of families of resonant periodic orbits in Hamiltonian systems

description: We investigate the evolution of families of periodic orbits in a bisymmetrical potential made up of a two-dimensional harmonic oscillator with only one quartic perturbing term, in a number of resonant cases. Our main objective is to compute sufficiently and accurately the position and the period of the periodic orbits. For the derivation of the above quantities (position and period) we deploy in each resonance case semi-numerical methods. The comparison of our semi-numerical results with those obtained by the numerical integration of the equations of motion indicates that, in every case the relative error is always less than 1% and therefore, the agreement is more than sufficient. Thus, we claim that semi-numerical methods are very effective tools for computing periodic orbits. We also study in detail, the case when the energy of the orbits is larger than the escape energy. In this case, the periodic orbits in almost all resonance families become unstable and eventually escape from the system. Our target is to calculate the escape period and the escape position of the periodic orbits and also monitor their evolution with respect to the value of the energy.

description: Radiant emittance of dimers and ensembles of particles consisting of gold, graphite and silica glass nanoparticles in vacuum is studied numerically based on the fluctuation-electromagnetic theory. The presence of neighboring particles of the same temperature causes an oscillating character of radiant emittance (per one particle) depending on the particle size, interparticle distance and temperature. We conclude that an ensemble of particles could be a much more intense source of thermal radiation than an equivalent solid body with the same outer surface area. Alternatively, when the neighboring particles create a significant screening effect (silica), an ensemble of particles could be a very good heat protector.

description: We present the bivariate neutral atomic hydrogen (HI)---stellar mass function (HISMF) (phi(M_HI, M_*)) for massive (log M_*/M_sun > 10) galaxies derived from a sample of 480 local (0.025 < z < 0.050) galaxies observed in HI at Arecibo as part of the GALEX Arecibo SDSS Survey (GASS). We fit six different models to the HISMF and find that a Schechter function that extends down to a 1% HI gas fraction, with an additional fractional contribution below that limit, is the best parametrization of the HISMF. We calculate Omega_{HI, M_* >10^10} and find that massive galaxies contribute 41% of the HI density in the local universe. In addition to the binned HISMF we derive a continuous bivariate fit, which reveals that the Schechter parameters only vary weakly with stellar mass: M_HI^*, the characteristic HI mass, scales as M_*^0.39, alpha, the slope of the HISMF at moderate HI masses, scales as M_*^0.07, and f, the fraction of galaxies with HI gas fraction greater than 1%, scales as M_*^-0.24. The variation of f with stellar mass should be a strong constraint for numerical simulations. To understand the physical mechanisms that produce the shape of the HISMF we redefine the parameters of the Schechter function as explicit functions of stellar mass and star formation rate to produce a trivariate fit. This analysis reveals strong trends with SFR. While M_HI^* varies weakly with stellar mass and SFR, alpha is a stronger function of both stellar mass and especially star formation rate. The HISMF is a crucial tool that can be used to constrain cosmological galaxy simulations, test observational predictions of the HI content of populations of galaxies, and identify galaxies whose properties deviate from average trends.

description: Cloud computing provides great benefits for applications hosted on the Web that also have special computational and storage requirements. This paper proposes an extensible and flexible architecture for integrating Wireless Sensor Networks with the Cloud. We have used REST based Web services as an interoperable application layer that can be directly integrated into other application domains for remote monitoring such as e-health care services, smart homes, or even vehicular area networks (VAN). For proof of concept, we have implemented a REST based Web services on an IP based low power WSN test bed, which enables data access from anywhere. The alert feature has also been implemented to notify users via email or tweets for monitoring data when they exceed values and events of interest.

Literaturverzeichnis zu "Alternative Baumarten – ein Lösungsbeitrag für die Klimaanpassung der Wälder in Niedersachsen?"

description: Im Rahmen der Klimaanpassung der Wälder ist das Interesse der forstlichen Praxis an sogenannten Alternativen Baumarten in den letzten Jahren vor dem Hintergrund der massiven Waldschäden stark gestiegen. Nach dem Ansatz der Klimaanalogien rücken aktuell vor allem südeuropäische und vorderasiatische Nadel- und Laubbaumarten in den Fokus, für die im Nordwestdeutschen Raum wissenschaftliche Anbauversuche jedoch überwiegend fehlen. Der Anbau dieser Arten birgt daher ökonomische, aber vor allem auch ökologische Risiken. Deshalb arbeitet die NW-FVA in einem aktuellen Forschungsprojekt daran, die größten Wissenslücken zu potenziell geeigneten Baumarten mit Hilfe von etablierten Praxisanbauten zu schließen. Erste Entscheidungshilfen für die Praxis sind nach Projektabschluss Ende 2023 zu erwarten.

description: Protecting quantum information from decoherence due to environmental noise is vital for fault-tolerant quantum computation. To this end, standard quantum error correction employs parallel projective measurements of individual particles, which makes the system extremely complicated. Here we propose measurement-free topological protection in two dimension without any selective addressing of individual particles. We make use of engineered dissipative dynamics and feedback operations to reduce the entropy generated by decoherence in such a way that quantum information is topologically protected. We calculate an error threshold, below which quantum information is protected, without assuming selective addressing, projective measurements, nor instantaneous classical processing. All physical operations are local and translationally invariant, and no parallel projective measurement is required, which implies high scalability. Furthermore, since the engineered dissipative dynamics we utilized has been well studied in quantum simulation, the proposed scheme can be a promising route progressing from quantum simulation to fault-tolerant quantum information processing.

description: "As taken from a practice American Foreign Service Officer Examination, one of the many US civil service exams, this question exemplifies the influence express purpose of advancing members of under-privileged minorities toward leadership positions. Although the rationale behind this program is quite noble, what affect is it having on our nation as a whole? Prior to the conception of this program, our nation operated, ideally, with a policy of "advancement to the most deserving." Unfortunately racism and the nepotism of "old boy networks" were impurities in the system that needed to be eradicated. If the goal of the program's creators was to force-feed minorities into the establishment with total disregard to both level of qualification and the efficiency of the bureaucracy then, in effect, they were successful. But most would maintain that this was not the intention.
Another motivating factor behind the implementation of affirmative action was the relatively small number of minority role models in high-level positions in corporate America and the government. Without such models, it was thought that there would be no motivation for any member of a minority group to aspire to reach such high plateaus in American society. The attempt to create ethnic role models was also clear through the admissions policies of many universities and colleges. But in actuality, does this social advancement program achieve its goals?"--from pages 31

description: "According to standard Hollywood practice, Buchwald or any other writer is not promised a share of the true profits in a contract. Royalties to writers and other creative people under contract are paid out only after the movie company deducts from gross revenue their distribution fees (a percentage based on what the company thinks is appropriate—usually about 30 percent) leaving an adjusted gross revenue. Against roughly 70 percent of the revenues the studios apply 100 percent of the costs for purpose of determining the participation rights of writers and performers. Because there are essentially two categories created by this accounting system (what the studio makes and what the film makes), the studios profit handsomely while the film shows a loss —meaning no royalties for actors, directors, and writers. Using this formula, Paramount could claim that Coming to America, the second-highest grossing movie in 1988, was $18,000 in the red and would never show a profit. This calls into question whether the system that is being used in the drawing up of movie contracts is fair and equitable."--from pages 33
