There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

YAGO: A Large Ontology from Wikipedia and WordNet

The growing use of XML in commercial as well as non-commercial domains to transport information poses new challenges to concepts to access this information. Common ways to access parts of a document use XPath-expressions. We provide a transformation of DTDs into a knowledge base in Description Logic. We use reasoning capabilities grounded in description logics to decide if a given XPath can be satisfied by a document, and to guide the search of XML-Processors into possibly successful branches of the document, thus avoiding parts of the document that will not yield results. The extension towards object oriented subclassing schemes opens this approach towards OODB-queries. In contrast to other approaches we do not use any kind of graph representing the document structure, and no steps towards incorporation of the XML/OODB-processor itself will be taken.

Optimizing the evaluation of XPath using description logics

Instance-based methods are a specific class of methods for automated proof search in first-order logic. This article provides an overview of the major methods in the area and discusses their properties and relations to the more established resolution methods. It also discusses some recent trends on refinements and applications. 
This overview is rather brief and informal, but we provide a comprehensive literature list to follow-up on the details.

Current approaches to analyzing dynamic systems are mostly grounded in propositional (temporal) logics. As a consequence, they often lack expressivity for modelling rich data structures and reasoning about them in the course of a computation. To address this problem, we propose a rich modelling framework based on first-order logic over background theories (arithmetics, lists, records, etc) and state transition systems over corresponding interpretations. On the reasoning side, we introduce a tableau calculus for bounded model checking of properties expressed in a certain fragment of CTL* over that first-order logic. We also describe a k-induction scheme on top of that calculus for proving safety properties, and we report on first experiments with a prototypical implementation.

Detailed field mapping, isotopic and palaeontologic dating in the Nicoya area has revealed coeval preCampanian, middle to late Cretaceous sedimentary/magmatic sequences of different geodynamic palaeoenvironments. 1The Nicoya Complex is a pile of plateau basalts and intrusives of Berriasian to Campanian igneous ages, including Middle Jurassic to Santonian radiolaritic sediments only. This unit is the subject of another abstract (this volume). 2The Matambu Terrane comprises a basaltic basement of unknown origin and age, overlain by bituminous, siliceous shales of late Albian age (Loma Chumico Formation). This formation seems to be thermally affected by younger basaltic flows and intrusives of Cenomanian to early Campanian age that may be part of the Nicoya (plateau) Complex. The Loma Chumico Formation is overlain by pelagic, hemipelagic and turbiditic siliceous and calcareous shales and mudstones assigned to the redefined Sabana Grande Formation (palaeontologically undated, but estimated as Cenomanian to Coniancian in age). Upsection, the Nambi Formation (Flores et al. 2003) is characterized by volcaniclastic turbidities that document erosion of the (nearby) Nicoya Complex. A preliminary Sr/Sr isotopic analysis of Inoceramus gave a value of 0.70738 that can be interpreted as a Coniacian age. The top of Nambi is marked by the presence of reworked Campanian shallow water bioclasts, announcing the transition to the overlap sediments (see below). 3The Manzanillo Terrane is floored by a basaltic basement intruded by the Tortugual Komatiitic Suite (Alvarado et al. 1997) of Turonian (89 ma) age. The sedimentary cover is characterized by a thick hemipelagic-turbiditic sequence containing arc-derived volcaniclastic deposits called Berrugate Formation (Flores et al. 2003). This formation has been dated by radiolarian biochronology as Coniancian in age (Dictyomitra koslovae, Pseudoaulophacus florensis, Pseudoaulophacus lenticulatus and Theocampe salillum associated with Stichomitra communis), but may range up to the lower Campanian. The Manzanillo Terrane documents pre-Campanian evolved arc volcanism that must have resulted from active subduction of “normal” ocean floor. This ocean floor was located between the exotic Nicoya Complex (1) /Matambu Terrane (2), and the Manzanillo Terrane (3). The Manzanillo Terrane could represent a fore-arc area at the foot of the western edge of the future Caribbean Plate. Subduction stopped when (1) and (2) reached the trench and collided with the Caribbean Plate during the Campanian. Di Marco et al. (1995) provided evidence for Late Campanian-Maastrichtian southern hemisphere palaeolatitudes in two sections of the Figure 1 Terranes proposed in Nicoya area
