Two-way Networks: when Adaptation is Useless

description: In two-way networks, nodes act as both sources and destinations of messages. This allows for "adaptation" at or "interaction" between the nodes - a node's channel inputs may be functions of its message(s) and previously received signals. How to best adapt is key to two-way communication, rendering it challenging. However, examples exist of point-to-point channels where adaptation is not beneficial from a capacity perspective. We ask whether analogous examples exist for multi-user two-way networks. We first consider deterministic two-way channel models: the binary modulo-2 addition channel and a generalization thereof, and the linear deterministic channel. For these deterministic models we obtain the capacity region for the two-way multiple access/broadcast channel, the two-way Z channel and the two-way interference channel (IC). In all cases we permit all nodes to adapt channel inputs to past outputs (except for portions of the linear deterministic two-way IC where we only permit 2 of the 4 nodes to fully adapt). However, we show that this adaptation is useless from a capacity region perspective and capacity is achieved by strategies where the channel inputs at each use do not adapt to previous inputs. Finally, we consider the Gaussian two-way IC, and show that partial adaptation is useless when the interference is very strong. In the strong and weak interference regimes, we show that the non-adaptive Han and Kobayashi scheme utilized in parallel in both directions achieves to within a constant gap for the symmetric rate of the fully (some regimes) or partially (remaining regimes) adaptive models. The central technical contribution is the derivation of new, computable outer bounds which allow for adaptation. Inner bounds follow from non-adaptive achievability schemes of the corresponding one-way channel models.

description: The deterministic relationship between cause and effect is deeply connected with our understanding of the physical sciences and their explanatory ambitions. Though progress is being made, the lack of theoretical predictions and experiments in quantum gravity makes it difficult to use empirical evidence to justify a theory of causality at quantum level in normal circumstances, i. e. by predicting the value of a well-confirmed experimental result. For a variety of reasons, the problem of the deterministic relationship between cause and effect is related to basic problems of physics as such. Despite the common belief, it is a remarkable fact that a theory of causality should be consistent with a theory of everything and is because of this linked to problems of a theory of everything. Thus far, solving the problem of causality will help us to solve the problems of the theory of everything (at quantum level).

description: Mit der ökologischen Steuerreform wurden von 1999 bis 2003 die Energiesteuersätze – insbesondere auf Benzin und Diesel – erhöht und eine Stromsteuer eingeführt. Heute erzielen diese Ökosteuererhöhungen ein jährliches Aufkommen von etwa 20 Milliarden Euro oder 0,6 Prozent des Bruttoinlandsprodukts. Damit werden höhere Bundeszuschüsse an die Rentenversicherung finanziert. Berechnungen auf Basis eines Renten-Simulationsmodells zeigen, dass der Rentenbeitragssatz derzeit um 1,2 Prozentpunkte niedriger und die Renten um 1,5 Prozent höher liegen, als dies ohne die höheren Bundeszuschüsse der Fall wäre. Eine Mikrosimulationsanalyse ergibt, dass die ökologische Steuerreform für die privaten Haushalte insgesamt aufkommens- und belastungsneutral ist. Für unterschiedliche Einkommensgruppen und soziale Gruppen ergeben sich aber Be- und Entlastungen. So werden vor allem Arbeitnehmer- und Rentnerhaushalte mit mittleren Einkommen entlastet. Haushalte mit geringen Einkommen werden sogar belastet, ebenso PendlerInnen mit langen Arbeitswegen. Diese Verteilungswirkungen sollten bei einer Weiterentwicklung der ökologischen Steuern berücksichtigt werden.

description: Im April 1999 wurde die ökologische Steuerreform eingeführt. Vor dem Hintergrund dieses 20-jährigen Jubiläums nimmt dieser Wochenbericht eine Bestandsaufnahme der umweltpolitischen Effekte der Reform vor. Aufgrund der geringen Steuersätze war die Lenkungswirkung der Ökosteuer zur Vermeidung von Treibhausgasemissionen sehr gering. Ferner können uneinheitliche Steuersätze auf verschiedene Energieträger zu Effizienzverlusten führen. Um die Lenkungswirkung zu verbessern, sollte die Ökosteuer konsequenter an Klimazielen ausgerichtet sein, das heißt die Steuersätze auf Heiz- und Kraftstoffe sollten steigen und stärker CO2-basiert gestaltet werden. Hierbei sollte die Besteuerung mit den bestehenden Instrumenten zur mittel- bis langfristigen Umsetzung der Energiewende stärker abgestimmt werden.

description: For n\geq 2, there is a free field realization of the affine vertex superalgebra A associated to psl(n|n) at critical level inside the bcβγsystem W of rank n^2. We show that the commutant C=Com(A,W) is purely bosonic and is freely generated by n+1 fields. We identify the Zhu algebra of C with the ring of invariant differential operators on the space of n\times n matrices under SL_n \times SL_n, and we classify the irreducible, admissible C-modules with finite dimensional graded pieces. For n\leq 4, C is isomorphic to the W_n^{(2)}-algebra at critical level, and we conjecture that this holds for all n.

The lifestyle and health of Saudi women with special reference to type 2 diabetes mellitus
Creators: name: Al-Bannay, Hana
Publisher: name: University of British Columbia
Year: 2013

description: Although the health of Saudi women has been severely compromised by lifestyle-related conditions like Type 2 Diabetes Mellitus (T2DM), this topic has been understudied particularly in relation to women’s cultural and religious contexts. This thesis constitutes exploratory work with the aim of informing lifestyle-related health studies for women in Saudi Arabia. Its objectives included: Study One, to examine Saudi women’s lifestyle-related health beliefs and behaviours and their understanding of religious teachings in relation to health behaviours and; Study Two, to explore the outcomes of a pilot intervention study of a T2DM education program, based on international standards and adapted to participants’ cultural and religious contexts, and compare outcomes of this intervention with outcomes of usual care for diabetes in Saudi Arabia. The studies were conducted in Dammam, Saudi Arabia. In Study One, a cross-section of women (n=407) participated in interviews based on a survey questionnaire about lifestyle-related health beliefs and behaviours, and related religious teachings. In Study Two, women at risk of or diagnosed with T2DM (n=35 including drop-outs) were assigned to two groups; an Intervention Group participated in a T2DM education program, based on international standards and tailored to Saudi women’s cultural and religious contexts, and a Usual Care Group received the usual care for diabetes in Saudi Arabia. Outcomes included blood glucose, body composition, six-minute walk test, life satisfaction, quality of life, and diabetes knowledge. At the end of the study, the Intervention Group participated in a focus group discussion of their program experience. For the analysis of our data, we used mixed methods; descriptive statistics (SPSSv.20) were used to analyze the quantitative data and Atlas.ti® software to code themes in the qualitative data. Results from Study One showed that Saudi women commonly report lifestyle-related conditions that are associated with unhealthy behaviours in contrast to their positive beliefs about healthy lifestyle and their understanding of related Islamic teachings. Study Two showed that Saudi women may benefit from a T2DM education program, based on international standards and adapted to their cultural and religious contexts. These findings provide several avenues for future research related to the health of Saudi women.

description: This paper introduces a probability density estimator based on Green's function identities. A density model is constructed under the sole assumption that the probability density is differentiable. The method is implemented as a binary likelihood estimator for classification purposes, so issues such as mis-modeling and overtraining are also discussed. The identity behind the density estimator can be interpreted as a real-valued, non-scalar kernel method which is able to reconstruct differentiable density functions.

description: Using a microscopic transport model we investigate the evolution of conical structures originating from the supersonic projectile moving through the hot matter of ultrarelativistic particles. Using different scenarios for the interaction between projectile and matter, and different transport properties of the matter, we study the formation and structure of Mach cones. Especially, a dependence of the Mach cone angle on the details and rate of the energy deposition from projectile to the matter is investigated. Furthermore, the two-particle correlations extracted from the numerical calculations are compared to an analytical approximation. We find that the propagation of a high energetic particle through the matter does not lead to the appearance of a double peak structure as observed in the ultrarelativistic heavy-ion collision experiments. The reason is the strongly forward-peaked energy and momentum deposition in the head shock region. In addition, by adjusting the cross section we investigate the influence of the viscosity to the structure of Mach cones. A clear and unavoidable smearing of the profile depending on a finite ratio of shear viscosity to entropy density is clearly visible.

description: Constant composition codes have been proposed as suitable coding schemes to solve the narrow band and impulse noise problems associated with powerline communication. In particular, a certain class of constant composition codes called frequency permutation arrays have been suggested as ideal, in some sense, for these purposes. In this paper we characterise a family of neighbour transitive codes in Hamming graphs in which frequency permutation arrays play a central rode. We also classify all the permutation codes generated by groups in this family.
The effect of the linear term on the wavelet estimator of primordial non-Gaussianity

description: In this work we present constraints on different shapes of primordial non-Gaussianity using the Wilkinson Microwave Anisotropy Probe (WMAP) 7-year data and the spherical Mexican hat wavelet fnl estimator including the linear term correction. In particular we focus on the local, equilateral and orthogonal shapes. We first analyse the main statistical properties of the wavelet estimator and show the conditions to reach optimality. We include the linear term correction in our estimators and compare the estimates with the values already published using only the cubic term. The estimators are tested with realistic WMAP simulations with anisotropic noise and the WMAP KQ75 sky cut. The inclusion of the linear term correction shows a negligible improvement (< 1 per cent) in the error-bar for any of the shapes considered. The results of this analysis show that, in the particular case of the wavelet estimator, the optimality for WMAP anisotropy levels is basically achieved with the mean subtraction and in practical terms there is no need of including a linear term once the mean has been subtracted. Our best estimates are now: local fnl = 39.0 +/ 21.4, equilateral fnl = -62.8 +/- 154.0 and orthogonal fnl = -159.8 +/- 115.1 (all cases 68 per cent CL). We have also computed the expected linear term correction for simulated Planck maps with anisotropic noise at 143 GHz following the Planck Sky Model and including a mask. The improvement achieved in this case for the local fnl error-bar is also negligible (0.4 per cent).

description: Representations are internal models of the environment that can provide guidance to a behaving agent, even in the absence of sensory information. It is not clear how representations are developed and whether or not they are necessary or even essential for intelligent behavior. We argue here that the ability to represent relevant features of the environment is the expected consequence of an adaptive process, give a formal definition of representation based on information theory, and quantify it with a measure R. To measure how R changes over time, we evolve two types of networks---an artificial neural network and a network of hidden Markov gates---to solve a categorization task using a genetic algorithm. We find that the capacity to represent increases during evolutionary adaptation, and that agents form representations of their environment during their lifetime. This ability allows the agents to act on sensorial inputs in the context of their acquired representations and enables complex and context-dependent behavior. We examine which concepts (features of the environment) our networks are representing, how the representations are logically encoded in the networks, and how they form as an agent behaves to solve a task. We conclude that R should be able to quantify the representations within any cognitive system, and should be predictive of an agent's long-term adaptive success.

description: Psychische Erkrankungen, beispielsweise Depressionen, haben in den vergangenen Jahrzenten weltweit an Bedeutung gewonnen. Da diese nicht nur mit erheblichen Einschränkungen für die Betroffenen selbst verbunden sind, sondern auch einen hohen Kostenfaktor für die Allgemeinheit darstellen, wird die Frage nach potentiellen Einflussfaktoren immer relevanter. Die vorliegende Studie untersucht auf Basis des Sozio-oekonomischen Panels (SOEP), welche Rolle die Schulbildung der Mutter für die psychische Gesundheit ihrer Kinder im Erwachsenenalter spielt. Konkret wird der Effekt der Erhöhung der Pflichtschulzeit in Westdeutschland um ein Jahr in den 1940er bis 1960er Jahren betrachtet. Das Ergebnis: Die psychische Gesundheit der Töchter im Erwachsenenalter verringerte sich leicht. Für die Söhne und bei Betrachtung aller Kinder zusammen zeigen sich hingegen keine Effekte. Dabei muss beachtet werden, dass die Schulreform – wie andere Studien ergaben – auch positive Effekte hatte, etwa auf die Gesundheit der Mütter oder die Bildung der Kinder.

description: First, we present some results about the Hölder continuity of the sample paths of so called dilatively stable processes which are certain infinitely divisible processes having a more general scaling property than self-similarity. As a corollary, we obtain that the most important (H,delta)-dilatively stable limit processes (e.g., the LISOU and the LISCBI processes, see Igloi [4]) almost surely have a local Hölder exponent H. Next we prove that, under some slight regularity assumptions, any two dilatively stable processes with stationary increments are singular (in the sense that their distributions have disjoint supports) if their parameters H are different. We also study the more general case of not having stationary increments. Throughout the paper we specialize our results to some basic dilatively stable processes such as the above-mentioned limit processes and the fractional Lévy process.

description: Ein niedrigerer Bildungsabschluss der Mutter geht mit einer geringeren Lebenserwartung einher. Personen, die eine Mutter mit einem Volksschul- oder gar keinem Schulabschluss haben, sterben im Alter ab 65 Jahren im Durchschnitt zwei Jahre früher als Personen, deren Mütter mindestens einen Realschulabschluss haben. Die Bildung der Mutter erklärt unabhängig von der eigenen Bildung und dem Einkommen einer Person Mortalitätsunterschiede. Zwischen der Lebenserwartung und der Bildung des Vaters zeigt sich hingegen kein signifikanter Zusammenhang, wie dieser Bericht auf Basis des Sozio-oekonomischen Panels (SOEP) zeigt. Die Untersuchung ist eine der ersten, die für Deutschland die Verbindung der Lebenserwartung mit der Bildung der Eltern analysiert. Die Ergebnisse zeigen, dass mehr Bildung mit Vorteilen zusammenhängt, die sich auch auf die nachfolgende Generation übertragen. Daher sollte Kindern aus sozial schwächeren Haushalten eine bessere Nutzung ihrer individuellen Potentiale ermöglicht werden, etwa durch den Ausbau einer qualitativ hochwertigen frühkindlichen Förderung.

Equilibrium Properties of Quantum Spin Systems with Non-additive Long-Range Interactions

Publisher: name: arXiv
Year: 2012
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study equilibrium states of quantum spin systems with non-additive long-range interactions by adopting an appropriate scaling of the interaction strength, i.e., the so called Kac prescription. In classical spin systems, it is known that the equilibrium free energy is obtained by minimizing the free energy functional over the coarse-grained magnetization. Here we show that it is also true for quantum spin systems. From this observation, it is found that when the canonical ensemble and the microcanonical ensemble are not equivalent in some parameter region, it is not necessarily justified to replace the actual long-range interaction by the infinite-range interaction (Curie-Weiss type interaction). On the other hand, in the parameter region where the two ensembles are equivalent, this replacement is always justified. We examine the Heisenberg XXZ model as an illustrative example, and discuss the relation to experiments.

description: A logarithmic spiral is a prominent feature appearing in a majority of observed galaxies. This feature has long been associated with the traditional Hubble classification scheme, but historical quotes of pitch angle of spiral galaxies have been almost exclusively qualitative. We have developed a methodology, utilizing two-dimensional fast Fourier transformations of images of spiral galaxies, in order to isolate and measure the pitch angles of their spiral arms. Our technique provides a quantitative way to measure this morphological feature. This will allow comparison of spiral galaxy pitch angle to other galactic parameters and test spiral arm genesis theories. In this work, we detail our image processing and analysis of spiral galaxy images and discuss the robustness of our analysis techniques.

description: We study the correlations of heavy quarks produced in relativistic heavy ion collisions and find them to be quite sensitive to the effects of the medium and the production mechanisms. In order to put this on a quantitative footing, as a first step, we analyze the azimuthal, transverse momentum, and rapidity correlations of heavy quark-anti quark ($Q\overline{Q}$) pairs in $pp$ collisions at $\cal{O}$($α_{s}^{3}$). This sets the stage for the identification and study of medium modification of similar correlations in relativistic collision of heavy nuclei at the Large Hadron Collider. Next we study the additional production of charm quarks in heavy ion collisions due to multiple scatterings, {\it viz.}, jet-jet collisions, jet-thermal collisions, and thermal interactions. We find that these give rise to azimuthal correlations which are quite different from those arising from prompt initial production at leading order and at next to leading order.

The Maxwell and Navier-Stokes that Follow from Einstein Equation in a Spacetime Containing a Killing Vector Field

description: In this paper we are concerned to reveal that any spacetime structure \slg,D,τ_{[sg]\sslg},\uparrow>, which is a model of a gravitational field in General Relativity generated by an energy-momentum tensor T --- and which contains at least one nontrivial Killing vector field A --- is such that the 2-form field F=dA (where A=[g]\slg(A,)) satisfies a Maxwell like equation --- with a well determined current that contains a term of the superconducting type--- which follows directly from Einstein equation. Moreover, we show that the resulting Maxwell like equations, under an additional condition imposed to the Killing vector field, may be written as a Navier-Stokes like equation as well. As a result, we have a set consisting of Einstein, Maxwell and Navier-Stokes equations that follows sequentially from the first one under precise mathematical conditions and once some identifications about field variables are evinced, as detailed explained throughout the text. We compare and emulate our results with others on the same subject appearing in the literature.

description: Heisenberg’s uncertainty principle as the heart and the cornerstone of the Copenhagen Interpretation of quantum mechanics and as one of the most powerful weapons against causality in micro- and macrophysics is refuted. My contribution will make the prove that Heisenberg’s uncertainty principle is based on a logical contradiction and leads to a logical contradiction. If we accept
 Heisenberg’s uncertainty principle as valid we must accept that 0 = 1.
Fluid-structure interaction and wetting of soft polymer substrates

description: At the Leibniz MMS Days 2025 at the Leibniz Institute for Baltic Sea Research (IOW) in Warnemünde, this joint work on the equilibrium shapes of liquid polystyrene (PS) droplets on soft viscoelastic PDMS substrates was presented. Combining high-resolution atomic force microscopy with axisymmetric sharp-interface modeling, it was investigated how substrate elasticity and droplet size influence droplet morphology. The comparison showed systematic deviations, for which a qualitative explanation is provided using poroelastic models.

This is joint work with André Erhardt, Leonie Schmeller, and Barbara Wagner (WIAS Berlin), and Ralf Seemann and Khalil Remini (University of Saarland).

description: Το αντικείμενο μελέτης της συγκεκριμένης μεταπτυχιακής διπλωματικής εργασίας προέκυψε μετά από την αναζήτηση εναλλακτικών τεχνικών και υλικών δόμησης για την επίτευξη ενός βιοκλιματικού σχεδιασμού. Τα υλικά που επιλέχθηκαν και αναλύθηκαν διεξοδικά είναι το σκυρόδεμα κάνναβης για το χαμηλό του ανθρακικό αποτύπωμα από τη διαδικασία φύτευσης έως την εγκατάσταση και η διαφανής θερμομόνωση καθώς χαρακτηρίζεται από τη χαμηλή κατανάλωση ενέργειας της κατοικίας χάρη στη δομή της. Στη συνέχεια, θέλοντας η έρευνα αυτή να αποτελέσει ένα επιπλέον κίνητρο προς τον κατασκευαστικό κλάδο στην Ελλάδα για τον περιορισμό της χρήσης συμβατικών υλικών προς όφελος του πλανήτη, εκπονήθηκε μία προσομοίωση μελέτης περίπτωσης μέσω του προγράμματος DesignBuilder. Σε αυτό το τμήμα, σχεδιάστηκε μία εφήμερη κατασκευή στην οποία πραγματοποιήθηκαν υπολογισμοί για την ενεργειακή συμπεριφορά των δύο υπό μελέτη υλικών, αλλά και για συμβατικά με σκοπό τη σύγκριση των αποτελεσμάτων
description: The subject that will be analyzed and reviewed in the thesis originated from the search for alternative building techniques and construction materials needed to achieve a bioclimatic design. After careful consideration, the chosen materials that will be thoroughly discussed are hempcrete and transparent insulation material (TIM), each for its own distinctive quality. More precisely, hempcrete was chosen due to its low carbon footprint from the planting process to the installation and transparent insulation material as it reduces the energy consumption of the house due to its unique structure. How can this paper help the sector evolve? A main objective of the following research is to benefit the planet by creating an incentive for the Greek construction industry to limit the use of conventional construction materials. A case study simulation trying to prove how these two materials can achieve that has been prepared using the DesignBuilder program. In this section, an ephemeral structure has been designed in which the energy behaviors of the two materials under study as well as the conventional ones are calculated in order to compare their results
