description: We consider the conformally invariant cubic wave equation on the Einstein cylinder $\mathbb{R} \times \mathbb{S}^3$ for small rotationally symmetric initial data. This simple equation captures many key challenges of nonlinear wave dynamics in confining geometries, while a conformal transformation relates it to a self-interacting conformally coupled scalar in four-dimensional anti-de Sitter spacetime (AdS$_4$) and connects it to various questions of AdS stability. We construct an effective infinite-dimensional time-averaged dynamical system accurately approximating the original equation in the weak field regime. It turns out that this effective system, which we call the conformal flow, exhibits some remarkable features, such as low-dimensional invariant subspaces, a wealth of stationary states (for which energy does not flow between the modes), as well as solutions with nontrivial exactly periodic energy flows. Based on these observations and close parallels to the cubic Szego equation, which was shown by Gerard and Grellier to be Lax-integrable, it is tempting to conjecture that the conformal flow and the corresponding weak field dynamics in AdS$_4$ are integrable as well.

description: Learning based on networks of real neurons, and by extension biologically inspired models of neural networks, has yet to find general learning rules leading to widespread applications. In this paper, we argue for the existence of a principle allowing to steer the dynamics of a biologically inspired neural network. Using carefully timed external stimulation, the network can be driven towards a desired dynamical state. We term this principle "Learning by Stimulation Avoidance" (LSA). We demonstrate through simulation that the minimal sufficient conditions leading to LSA in artificial networks are also sufficient to reproduce learning results similar to those obtained in biological neurons by Shahaf and Marom [1]. We examine the mechanism's basic dynamics in a reduced network, and demonstrate how it scales up to a network of 100 neurons. We show that LSA has a higher explanatory power than existing hypotheses about the response of biological neural networks to external simulation, and can be used as a learning rule for an embodied application: learning of wall avoidance by a simulated robot. The surge in popularity of artificial neural networks is mostly directed to disembodied models of neurons with biologically irrelevant dynamics: to the authors' knowledge, this is the first work demonstrating sensory-motor learning with random spiking networks through pure Hebbian learning.

description: Laryngeal contrasts in consonants (e.g., voicing, aspiration, etc.) are found in nearly all languages. This talk presents acoustic data on laryngeal contrasts in Hadza, a language isolate spoken by ~1,200 people (Brian Wood, pc.). Hadza has a rich consonantal system with contrasts in laryngeal setting and airstream mechanism (e.g., pulmonic, glottalic, and lingual occlusives). Some previous descriptions of Hadza suggested a three-way contrast in coronal stops (e.g., /t tʰ d/), and a four-way contrast in non-coronal stops (e.g., /k kʰ kʼ ɡ/ and affricates (e.g., t͡s t͡sʰ t͡sʼ d͡z), and also a three-way contrast in clicks (e.g., /! !ʰ ǃʔ/) (Tucker et al. 1977; de Voogt 1992). However, these studies did not offer corroborating phonetic evidence. Voice Onset Time (VOT)—the time difference between the release of a stop closure and onset of vocal fold vibration—has proven to be a useful (albeit imperfect) phonetic exponent in the realization of laryngeal contrasts cross-linguistically (Lisker & Abramson 1964). Sands et al. (1996) documented the expected distinction in VOT between voiceless unaspirated and aspirated stops in Hadza, but they did not find significant VOT differences for clicks or affricates. Using wordlist data collected in 2022, this talk presents an analysis of VOT in Hadza stops, affricates, and clicks to examine the temporal properties of laryngeal contrasts. In particular, we examine the differences in VOT between unaspirated, aspirated, and ejective stops and affricates and the differences between unaspirated, aspirated, and glottalized clicks. These results resolve discrepancies between past research and confirm an aspiration contrast in affricates and clicks previously unsubstantiated in the literature.

description: The Quantum renormalization group (QRG) is a realisation of holography through a coarse graining prescription that maps the beta functions of a quantum field theory thought to live on the `boundary' of some space to holographic actions in the `bulk' of this space. A consistency condition will be proposed that translates into general covariance of the gravitational theory in the $D + 1$ dimensional bulk. This emerges from the application of the QRG on a planar matrix field theory living on the $D$ dimensional boundary. This will be a particular form of the Wess--Zumino consistency condition that the generating functional of the boundary theory needs to satisfy. In the bulk, this condition forces the Poisson bracket algebra of the scalar and vector constraints of the dual gravitational theory to close in a very specific manner, namely, the manner in which the corresponding constraints of general relativity do. A number of features of the gravitational theory will be fixed as a consequence of this form of the Poisson bracket algebra. In particular, it will require the metric beta function to be of gradient form.

description: This article studies sufficient conditions on families of approximating kernels which provide $N$--term approximation errors from an associated nonlinear approximation space which match the best known orders of $N$--term wavelet expansion. These conditions provide a framework which encompasses some notable approximation kernels including splines, so-called cardinal functions, and many radial basis functions such as the Gaussians and general multiquadrics. Examples of such kernels are given to justify the criteria, and some computational experiments are done to demonstrate the theoretical results. Additionally, the techniques involved allow for some new results on $N$--term interpolation of Sobolev functions via radial basis functions.

The Exact Rate-Memory Tradeoff for Caching with Uncoded Prefetching

description: We consider a basic cache network, in which a single server is connected to multiple users via a shared bottleneck link. The server has a database of files (content). Each user has an isolated memory that can be used to cache content in a prefetching phase. In a following delivery phase, each user requests a file from the database, and the server needs to deliver users' demands as efficiently as possible by taking into account their cache contents. We focus on an important and commonly used class of prefetching schemes, where the caches are filled with uncoded data. We provide the exact characterization of the rate-memory tradeoff for this problem, by deriving both the minimum average rate (for a uniform file popularity) and the minimum peak rate required on the bottleneck link for a given cache size available at each user. In particular, we propose a novel caching scheme, which strictly improves the state of the art by exploiting commonality among user demands. We then demonstrate the exact optimality of our proposed scheme through a matching converse, by dividing the set of all demands into types, and showing that the placement phase in the proposed caching scheme is universally optimal for all types. Using these techniques, we also fully characterize the rate-memory tradeoff for a decentralized setting, in which users fill out their cache content without any coordination.

description: We determine the p->q norms of the Gaussian one-mode quantum-limited attenuator and amplifier and prove that they are achieved by Gaussian states, extending to noncommutative probability the seminal theorem "Gaussian kernels have only Gaussian maximizers" (Lieb in Invent Math 102(1):179-208, 1990). The quantum-limited attenuator and amplifier are the building blocks of quantum Gaussian channels, which play a key role in quantum communication theory since they model in the quantum regime the attenuation and the noise affecting any electromagnetic signal. Our result is crucial to prove the longstanding conjecture stating that Gaussian input states minimize the output entropy of one-mode phase-covariant quantum Gaussian channels for fixed input entropy. Our proof technique is based on a new noncommutative logarithmic Sobolev inequality, and it can be used to determine the p->q norms of any quantum semigroup.

description: This paper examines the efficacy of nominal yield curve term structure on inflation predictability incorporating economic variables expressed in the form of the Quantity Theory of Money. We document a positive predictability of the term structure in predicting the current reported inflation rate (Nowcast) and one-month ahead (Forecast) reported inflation rate in the US from 2018 to 2022. However, this level of predictability is not constant across different inflation regimes. The significant predictors in the low inflation regimes deviate to those in the high inflation regimes, suggesting that economic indicators should be considered dynamically. Lastly, we made use of nonparametric method (K-Nearest Neighbors) for predicting extreme inflation regimes in consideration of their pattern recognition ability at higher dimensions, as well as ability to handle nonlinearity.

description: We study three possible ways to circumvent the sign problem in the O(3) nonlinear sigma model in 1+1 dimensions. We compare the results of the worm algorithm to complex Langevin and multiparameter reweighting. Using the worm algorithm, the thermodynamics of the model is investigated, and continuum results are shown for the pressure at different $μ/T$ values in the range $0-4$. By performing $T=0$ simulations using the worm algorithm the Silver Blaze phenomenon is reproduced. Regarding the complex Langevin, we test various implementations of discretizing the complex Langevin equation. We found that the exponentialized Euler discretization of the Langevin equation gives wrong results for the action and the density at low $T/m$. By performing continuum extrapolation we found that this discrepancy does not disappear and depends slightly on temperature. The discretization with spherical coordinates perform similarly at low $μ/T$, but goes wrong also at some higher temperatures at high $μ/T$. However, a third discretization that uses a constraining force to achieve the $ϕ^2 = 1$ condition gives correct results for the action, but wrong results for the density at low $μ/T$.

description: Subdiffusive motion takes place at a much slower timescale than diffusive motion. As a preliminary step to studying reaction-subdiffusion pulled fronts, we consider here the hyperbolic limit $(t,x) \to (t/\varepsilon, x/\varepsilon)$ of an age-structured equation describing the subdiffusive motion of, e.g., some protein inside a biological cell. Solutions of the rescaled equations are known to satisfy a Hamilton-Jacobi equation in the formal limit $\varepsilon \to 0$. In this work we derive uniform Lipschitz estimates, and establish the convergence towards the viscosity solution of the limiting Hamilton-Jacobi equation. The two main obstacles overcome in this work are the non-existence of an integrable stationary measure, and the importance of memory terms in subdiffusion.

description: Natur und Naturerlebnisse haben einen positiven Effekt auf die Gesundheit von Menschen, ganz besonders auf die Gesundheit von Kindern und Jugendlichen, die sich physisch, psychisch und kognitiv noch entwickeln und dafür Reize brauchen, wie die Natur sie bietet. Darum ist die Entwicklung und Gestaltung von kindergerechten und naturnahen Freiräumen heute ein wichtiges Anliegen, und hier wiederum ist Partizipation ein aktueller und oft geforderter Ansatz, denn partizipative Entwicklungsprojekte unterstützen die Identifikation mit dem Freiraum oder der Stadt. Allerdings bestand bislang kaum Interesse an der Frage, ob und welchen Einfluss die partizipativen Prozesse selbst auf gesundheitsrelevante Faktoren haben. Der Beitrag geht dieser Frage anhand eines konkreten, auf die Teilhabe von Kindern bei der Gestaltung von Freiräumen fokussierten Praxisbeispiels nach. Diskutiert werden relevante Aspekte im Hinblick auf Stadt- und Raumentwicklung, Gesundheit und deren Determinanten sowie Partizipation als Haltung und Methode. Es zeigt sich, dass partizipative Prozesse verschiedene gesundheitsrelevante Faktoren stimulieren: Empowerment und Autonomie, Selbstwirksamkeit, Attribution und Kontrollüberzeugungen sowie Kohärenzgefühl. Es fehlen aber empirische Untersuchungen zu den konkreten Voraussetzungen, Wirkmechanismen und Effekte solcher Prozesse. Hier gilt es eine Forschungslücke zu schliessen.

description: Background/Objectives: Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are often overlapping inflammatory diseases that occur in people older than 50 years. Both diseases can affect the quality of life, due to the burden of vascular inflammation and ischemia-related sympto (GCA), joint sympto (PMR) and systemic sympto (GCA and PMR), in addition to the side-effects of long-term treatment with glucocorticoids. We hypothesized that GCA and Phave both short- and long-term impact on the quality of life. We therefore documented patient reported outcomes (PROs) on the quality of life in GCA and Ppatients for five years. Methods: We prospectively followed treatment-naïve GCA (n=44) and P(n=40) patients since diagnosis for up to five years. At each visit, PROs were recorded by the Groningen Frailty Indicator (GFI), the Health Assessment Questionnaire-Disability Index (HAQ-DI) and the Short Form (SF)-36. Data were compared with age- and sex-matched healthy controls (HCs) that were also followed for up to five years. Results: At diagnosis, both GCA and Ppatients reported significantly worse on each PRO compared to HCs. On each of the eight domains of the SF-36, patients scored substantially lower than HCs, with Ppatients scoring slightly worse than GCA patients (Figure 1). Initiation of GC treatment rapidly improved PROs, however, scores either never recovered to HC values (GFI, SF-36) or increased again after two years (HAQ-DI). SF-36 scores at baseline and during treatment correlated the strongest with patient reported fatigue, rather than physician reported disease activity or levels of acute-phase markers. Conclusions: GCA and Ppatients experience both short-term and long-term impact on their quality of life, likely caused by both the disease and its treatment. The impact of fatigue in PROs, rather than disease-specific sympto, needs to be emphasized. Future studies should document whether a direct start of additional treatment such as methotrexate or tocilizumab substantially and persistently improve quality of life in these patients.

description: The potential of aqueous extract of the leaves of Acalypha wilkesiana, to protect against carbon tetrachloride induced liver damage was investigated in Wistar albino rats. The carbon tetrachloride was prepared 1:5 (v:v) in olive oil, and administered subcutaneously at 1 mL/kg body weight. The extract was administered to both normal and carbon tetrachloride treated rats at 100, 200 and 300 mg/kg. On fractionation and gas chromatographic analysis of the crude aqueous extract, thirty nine known alkaloids were detected, consisting mainly of akuamidine (69.027 %), voacangine (26.226 %), echitamine (1.974 %), echitamidine (0.599 %), lupanine (0.521 %) and augustamine (0.278 %). Compared to test control, the treatment dose dependently produced significantly lower (P<0.05) alkaline phosphatase, aspartate and alanine transaminase activities. Histopathological studies on the liver sections showed that pre-treatment with the extract protected against carbon tetrachloride induced fatty degeneration of hepatocytes, thus, confirming the results of the biochemical studies. The above results imply that treatment with the plant extract protects the liver against carbon tetrachloride induced hepatotoxicity, therefore, justifying the use of Acalypha wilkesiana in African traditional health care for the management of liver problems.

description: Missing data imputation can help improve the performance of prediction models in situations where missing data hide useful information. This paper compares methods for imputing missing categorical data for supervised classification tasks. We experiment on two machine learning benchmark datasets with missing categorical data, comparing classifiers trained on non-imputed (i.e., one-hot encoded) or imputed data with different levels of additional missing-data perturbation. We show imputation methods can increase predictive accuracy in the presence of missing-data perturbation, which can actually improve prediction accuracy by regularizing the classifier. We achieve the state-of-the-art on the Adult dataset with missing-data perturbation and k-nearest-neighbors (k-NN) imputation.

description: In this paper, we first present spectral conditions for the existence of $C_{n-1}$ in graphs (2-connected graphs) of order $n$, which are motivated by a conjecture of Erdős. Then we prove spectral conditions for the existence of Hamilton cycles in balanced bipartite graphs. This result presents a spectral analog of Moon-Moser's theorem on Hamilton cycles in balanced bipartite graphs, and extends a previous theorem due to Li and the second author for $n$ sufficiently large. We conclude this paper with two problems on tight spectral conditions for the existence of long cycles of given lengths.

description: En el escenario económico propio de la Región Caribe, caracterizado en la actualidad por una significativa complejidad, interactúan un sinnúmero de entidades que explotan diferentes actividades, poseen diferentes formas de constitución y organización, y persiguen una gran variedad de objetivos. Dentro de ese contexto se encuentran los clubes deportivos de fútbol o entes que fomentan y patrocinan organizadamente la práctica de ese deporte o modalidad con un enfoque empresarial. Este tipo de organizaciones son de marcada importancia para todas las regiones de Colombia, que tienen presencia, y en especial la Región Caribe, dado el impacto social y económico que generan en la población y el flujo de capitales que se teje alrededor del mismo.
The Impact of China and India on African Manufacturing Exports on the Third Market: Gravity Approach and A Test Of Flying - Geese Theory For Africa
Creators: name: G/Meskel, Atnafu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: In this paper, we address two major questions. First, the question of whether China and India displace the African manufacturing export from the third market and, secondly, the question of whether there is an evidence for shifting comparative advantage from China and India to Africa as predicted by the flying-geese theory of industrial development. The commodity is disaggregated down to three-digit SITC Rev.3 according to the UN Comtrade classification. We employed the gravity equation to test whether China and India are crowding out the African manufacturing exports from the third market. In contrast to most of the researches which estimate gravity model on averages of bilateral trade flows from cross-section data, we estimated the gravity model on panel data of imports of six third market countries from thirteen African exporter countries for the period 1995-2005. To test whether there is an evidence of shifting of comparative advantage from China and or India to Africa as predicted by flying-geese theory, we estimated Spearman's rank correlation coefficients on indices of the revealed comparative advantage vectors of the African exporters and China and India for the period 1995-2004. Both the gravity and flying-geese models predicted same outcome. The major finding of this paper is that there is strong evidence that China has been displacing African manufacturing from the third market but India has been complementing in the early years. However, the overall third market impact of China and India has been that of complementarity in the later years of the sample period. Furthermore, we found an evidence for shifting comparative advantage from China and India to Africa as the flying-geese theory predicts, South Africa being the leading goose. South Africa gained comparative advantage earlier than other African countries and moved to the higher stage of industrialization followed by Kenya. The major implication of this study is that, in the world where China and India are reshaping the global economic order dynamically, the outcomes of the traditionally received wisdom of trade liberalization and industrialization policies in the spirit of export promotion may be uncertain

description: El proyecto surge de la problemática ambiental que presentaron 18 estudiantes de la Institución Ednoeducativa el Hormiguero, de Santiago de Cali – Valle del Cauca, del programa Caminar en Secundaria II, que mostraron poco interés por cuidado y preservación de la flora y la fauna de su entorno escolar y comunitario. Por ello, se implementó un RED en las áreas de ciencias naturales y educación ambiental, que les permitiría desarrollar cualidades de amor, respeto, cuidado y preservación hacia el medio ambiente. El análisis de los resultados se realizaron mediante la estadística descriptiva, la que permitió concluir que la problemática ambiental presentada en la institución etnoeducativa por parte de los estudiantes es el manejo inadecuado de los residuos sólidos, los recursos naturales, así mismo la falta de conciencia, amor, identidad, sentido de pertenencia por el medio ambiente. De igual modo, no se encontró un trabajo interdisciplinario articulado al cuidado del medio ambiente, así que mediante la investigación se dio un avance para poder articular la temática de los Proyectos Ambientales Escolares (PRAE) y por último se concluyó que el proyecto pedagógico – didáctico logró mejorar las actitudes, la conciencia ambiental de sus participantes.

description: We investigate coherent transport over a finite square lattice in which the growth of bond percolation clusters are subjected to an Achlioptas type selection process, i.e., whether a bond will be placed or not depends on the sizes of clusters it may potentially connect. Different than the standard percolation where the growth of discrete clusters are completely random, clusters in this case grow in correlation with one another. We show that certain values of correlation strength, if chosen in a way to suppress the growth of the largest cluster which actually results in an explosive growth later on, may lead to more efficient transports than in the case of standard percolation, satisfied that certain fraction of total possible bonds are present in the lattice. In this case transport efficiency increases as a power function of bond fraction in the vicinity of where effective transport begins. It turns out that the higher correlation strengths may also reduce the efficiency as well. We also compare our results with those of the incoherent transport and examine the average spreading of eigenstates for different bond fractions. In this way, we demonstrate that structural differences of discrete clusters due to different correlations result in different localization properties.

description: Tanzania’s Rift Valley has been shown to feature linguistic diversity punctuated by remarkable convergences. This talk is a first effort at extending that analysis to the words people use to refer to their relatives. By way of context, this talk is a product of the University of Bayreuth course “Language and Meaning”, part of which was dedicated to kinship and kinship terminology across the African continent. Participants surveyed both lexical and ethnographic material from language communities across Africa, bringing together a wealth of material both lexical (kinship terms) and structural (kinship systems) in nature. This talk moblises this cross-continent data by employing it as a background against which languages of the Tanzanian Rift can be compared and contrasted, with the goal of asking questions about whether kinship terms and systems have been genetically inherited, affected by contact, or innovated in response to wider historical and social factors. Following an introductory survey of kinship terms and kinship systems of the Tanzanian Rift, the talk identifies patterns and attempts some initial investigations, using three kin relations as concrete examples: 1) siblings and cousins; 2) in-laws; and 3) the mother’s brother.
