This paper provides exact probability results for waiting times associated with occurrences of two types of motifs in a random sequence. First, we provide an explicit expression for the probability generating function of the interarrival time between two clumps of a pattern. It allows, in particular, to measure the quality of the Poisson approximation which is currently used for evaluation of t...

FeMn alloys show a great potential for the use as a biodegradable material for medical vascular implants. To optimize the material properties, with respect to the intended application, new fabrication methods also have to be investigated. In this work different Fe-FeMn32 multilayer films were deposited by magnetron sputtering. The deposition was done on a substrate structured by UV lithography....

Open source information on the internet can contribute significantly to intelligence assessments. Unfortunately, this information is mostly unstructured text, and varies widely in accuracy, focus, and level of impartiality. Though such unstructured information may be organized for convenient review in information portals, it is difficult to visualize, link, consolidate, summarize, compare, fuse...

OBJECTIVE To determine whether structured assessment of outpatient endometrial biopsies decreases the number of inconclusive samples. DESIGN Retrospective cohort study. SETTING Single hospital pathology laboratory. POPULATION Endometrial biopsy samples of 66 women with postmenopausal bleeding, collected during the usual diagnostic work-up and assessed as insufficient for a reliable histol...

eCMS is a web-based federated content management system for the support of distributed teaching based on an open, distributed middleware architecture for the publication, discovery, retrieval, and integration of educational material. The infrastructure supports the management of both standalone material and structured courses, as well as the integration of existing organized external repositori...

A levels of processing approach to memory was directly tested in a welldefined processing context by varying the depth to which spoken prose material could be processed. The effects of successively removing the semantic and the syntactic levels of analysis produced decrements in immediate recall that were structured according to the clausal segmentation of the material. The results corresponded...

The development of fundamental understanding in material science starts at the atomic level, where concerted movements set the properties of a material and its reaction upon the application of external factors. With the current development of nano-structured materials as e.g. metal-organic frameworks which can be used for energy storage applications, gaining insights into the dynamics that driv...

The design and experimental demonstration of an open cavity in the microwave region is presented. The resonance condition is achieved through the cancellation of lightpaths in positive and negative refractive index materials. The positive index material is a structured aluminium surface supporting a spoof surface plasmon mode, and the negative index material is a photonic crystal made of alumin...
