The term “digital repository” is used in disparate contexts, in both in a formal sense to describe a complex and complete preservation system and its policies, and in a more intuitive but less clearly defined sense, often implying simply a robust storage system, or a content management system. Lack of formalism in use of this term can impede development of formal requirements for building speci...

Currying is a transformation of term rewrite systems which may contain symbols of arbitrary arity into systems which contain only nullary symbols, together with a single binary symbol called application. We show that for all term rewrite systems (whether orthogonal or not) the following properties are preserved by this transformation: strong normalization, weak normalization, weak Church-Rosser...

Earth Observation (EO) Space Missions provide global coverage of the Earth by generating on a continuous basis huge amounts of data from a variety of sensors. Locating and accessing these historical data is a difficult process and their interpretation can be even more complicated given the fact that scientists may not have (or may not have access to) the right knowledge to interpret these data....

BACKGROUND No optimal methods for short-term hepatocyte preservation have been established. We have recently developed a prominent oxygen-permeable bag (Tohoku Device [TD]) for pancreatic islet culture and transplantation. In this study, we investigated whether TD is also effective for hepatocyte preservation and tried to optimize other conditions. METHODS Hepatocytes were preserved in the fo...

The preservation of digital publications involves various technical, legal, economic and organization issues. Copyright law and licensing arrangements may prevent problems for libraries that wish to preserve digital resources in the long-term or even short term. Digital preservation strategies involve copying and it is not clear with copyright legislation in the UK and Europe will allow the sor...

This study reports evidence that individuals with schizophrenia (SC) demonstrate intact attentional selection for visual working memory (WM) storage. A group of 62 participants with SC and 55 control participants without SC were studied in a series of 5 experiments that examined the ability to use top-down and bottom-up cues to guide WM encoding, as well as the ability to spontaneously select a...

This research will explore teaching styles of university professors. Teaching style is an umbrella term for teaching decisions made during the entire teaching process – planning, delivery, and evaluation. Contemporary university teachers are advised to adopt the learner-centred teaching style which is assumed to produce remarkable possibilities. In the Fall Semester 2015 fifty-two respondents i...

1. Object vision is largely invariant to changes of retinal images of objects in size and position. To reveal neuronal mechanisms of this invariance, we recorded activities from single cells in the anterior part of the inferotemporal cortex (anterior IT), determined the critical features for the activation of individual cells, and examined the effects of changes in stimulus size and position on...

Institutional repositories are considered an important method of capturing research outputs and disseminating them to a wider public. Thus far, the initial focus of activity has been on the process of establishing repositories and handling issues associated with the deposit of academic research. Given the experimental nature of many of these projects, few are able to dedicate staff or funding t...

The issues of digital preservation of shapes and internal structures of historical and cultural objects are discussed. An overview of existing approaches to computer modeling of shapes is presented and corresponding problems are considered. We propose a digital preservation paradigm quite different from the currently popular "scan and mesh" approach yielding visible surface models. Our approach...
