We present a domain-specific embedded language (DSEL) in Haskell that supports the philosophical study and practical explanation of causation. The language provides constructs for modeling situations comprised of events and functions for reliably determining the complex causal relationships that emerge between these events. It enables the creation of visual explanations of these causal relation...

Campbell (1996) reports that, for most countries, the unconditional correlation between quarterly stock returns and consumption growth is small in magnitude and sometimes even negative. Using a bivariate GARCH framework, we examine whether the conditional correlation between stock returns and consumption is positive, even if the unconditional correlation is not. Consistent with this, we find st...

INTRODUCTION The Short Form-12 version 2 (SF-12v2) is a shorter version of the Short Form-36 version 2 (SF-36v2) for assessing health-related quality of life. As the SF-12v2 could not be resolved into the physical- and mental-component summary score (PCS and MCS, respectively) in the general population of Singapore, this study aims to determine and validate the Singapore SF-12 version 2 (SG-12v...

The surface magnetization of the quantum XY chain in a transverse field is found for arbitrary nearest neighbour interactions in closed form. This allows to derive the bulk phase diagram in a simple way. The magnetic surface behaviour and the bulk correlation length are found exactly. We consider the ferromagnetic anisotropic XY quantum chain in a transverse field with hamiltonian [1] H = − N ∑

We present an analytic proof demonstrating the equivalence between the random phase approximation (RPA) to the ground state correlation energy and a ring-diagram simplification of the coupled cluster doubles (CCD) equations. In the CCD framework, the RPA equations can be solved in O(N(4)) computational effort, where N is proportional to the number of basis functions.

Systematic studies of global observables in different collision systems are indispensable for mapping the QCD phase diagram. Fluctuations in these quantities can provide fundamental information relevant for the phase transitions. The following global observables relevant to critical behavior are studied: the longitudinal density correlation, K to π and p to π fluctuations, and the constituent q...

Essays are frequently used as a medium for teaching and evaluating argumentation skills. Recently, there has been interest in diagrammatic outlining as a replacement to the written outline that often precedes essay writing. This paper presents a preliminary approach for automatically identifying diagram ontology elements in essays, and demonstrates its positive correlation with expert scores of...

UNLABELLED We introduce SharpViSu, an interactive open-source software with a graphical user interface, which allows performing processing steps for localization data in an integrated manner. This includes common features and new tools such as correction of chromatic aberrations, drift correction based on iterative cross-correlation calculations, selection of localization events, reconstruction...

this research discusses the process of designing a conceptual model for a new information system, i.e. electronic document management system. the new system is designed for an educational institute (itvhe) whose managers are the research population. the research methodology is based on structured analysis and design methodology (ssadm). in the end, the new system proposed using a data flow diag...

Long-term (up to 10000d) monitoring has been undertaken for 41 Seyferts in the near infrared (1.25 – 3.45μm). All but two showed variability, with amplitudes at K in the range < 0.1 to >1.1 mag. The timescale for detectable change is from about one week to a few years. Where contemporary observations of variability in x-rays, UV or visible light exist, it is found that the near-infrared varies ...
