Image Classification using Version Spaces

This paper presents the candidate elimination implementation of the version space strategy for classification of photographic data. It is shown that very accurate classification is easily achieved and that only a small number of training samples are needed to generate the rules

Predicting Puget Sound\u27s organic carbon—and why we need enhanced monitoring

How much has the total organic carbon deposited into the water column and sediments of Puget Sound increased due to human activity? How has that increase impacted sediment flux rates, hypoxia and the carbonate system balance? These are two important questions with answers that are still elusive. To date, both marine and freshwater organic carbon measurements in Puget Sound are relatively sparse. In the long-term, inadequate temporal and spatial organic carbon data may lead to an incomplete and incoherent understanding of carbon cycling in the Puget Sound. The Salish Sea Model, developed by PNNL in collaboration with Department of Ecology, provides insights into the extent of organic carbon loading and concentrations in the Puget Sound. Model scenario runs indicate that autochtonous organic detritus derived from increased productivity related to human nitrogen loading, combined with allochthonous carbon from direct loading due to human activity, has resulted in an increased loading of non-algal organic carbon ranging from 20 and 25% in a significant portion of the Puget Sound’s main basin, as well as in multiple inlets. This increase in organic carbon is expected to have an impact in heterotrophic respiration rates and eutrophication. This presentation will focus on loading rates and predicted organic carbon concentrations throughout the Puget Sound using the Salish Sea Model. It will point to the need for enhanced dissolved and particulate organic carbon measurements in our region, as well as basin-scale measurements of respiration rates, to optimize the alignment of on-going, long term monitoring and modeling efforts

Immunolocalization of TSOL18 and TSOL45-1A, the successful protective peptides against porcine cysticercosis, in Taenia solium oncospheres

Taenia solium life cycle includes humans as definitive hosts and pigs as intermediate hosts. One of the measures to stop the life cycle of this parasite is by vaccination of pigs. In experiments performed in pigs with TSOL18 and TSOL45-1A, two recombinant T. solium proteins, 99.5% and 97.0% protection was induced, respectively. The purpose of this paper was to localize these antigens in all stages of the parasite (adult worms, oncospheres and cysticerci) by immunofluorescence, with the use of antibodies against TSOL18 and TSOL45-1A that were obtained from the pigs used in the vaccination experiment. Results show that TSOL18 and TSOL45-1A are expressed on the surface of T. solium oncospheres and not in tapeworms or cysticerci, indicating that they are stage-specific antigens. This, therefore, might explain the high level of protection these antigens induce against pig cysticercosis

Data Acquisition, Management and Evaluation for Stone Conservation Projects with Digital Mapping

Several years of experience in heritage documentation have given a background to develop methods of digital photogrammetry and mapping. The outcome is the development of a mapping software over a period of 20 years.Main features of the software are image rectification, vector based mapping, quantity survey and data analysis. In Germany, it is mainly used in the field of stone conservation. Small projects can be processed as a single mapping project, whilst complex projects like a cathedral can be organised as a hierarchical project, with several mapping projects for individual object parts. Each mapped element can be connected with additional attributes. This allows visual analysis of mapping activities, quantities and attributes – like in a geographical information system (GIS) for conservators. Tools and procedures for efficient mapping are developed in close cooperation with conservators from different fields. It is shown how large stone objects can be managed efficiently with an example project from the field of natural stone. This applies to the overall data acquisition and data evaluation for condition analysis, conservation planning, accounting documentation and monitoring. Due to the advances in the fields 3D laser scanning and digital photogrammetry within the past 5 years the R&D project „PROQUATO“ (2016 – 2018) was initiated by fokus GmbH Leipzig with the institute for photogrammetry and remote sensing of TU Dresden and Scan 3D GmbH, Berlin. Project results for efficient data processing and functions for 3D mapping will be presented. Current developments deal with the fast processing of point clouds scanned by laser scanner for the use as reference for image rectification, deformation analysis and creation of section lines

A scalable readout system for a superconducting adiabatic quantum optimization system

We have designed, fabricated and tested an XY-addressable readout system that is specifically tailored for the reading of superconducting flux qubits in an integrated circuit that could enable adiabatic quantum optimization. In such a system, the flux qubits only need to be read at the end of an adiabatic evolution when quantum mechanical tunneling has been suppressed, thus simplifying many aspects of the readout process. The readout architecture for an $N$-qubit adiabatic quantum optimization system comprises $N$ hysteretic dc SQUIDs and $N$ rf SQUID latches controlled by $2\sqrt{N} + 2$ bias lines. The latching elements are coupled to the qubits and the dc SQUIDs are then coupled to the latching elements. This readout scheme provides two key advantages: First, the latching elements provide exceptional flux sensitivity that significantly exceeds what may be achieved by directly coupling the flux qubits to the dc SQUIDs using a practical mutual inductance. Second, the states of the latching elements are robust against the influence of ac currents generated by the switching of the hysteretic dc SQUIDs, thus allowing one to interrogate the latching elements repeatedly so as to mitigate the effects of stochastic switching of the dc SQUIDs. We demonstrate that it is possible to achieve single qubit read error rates of $<10^{-6}$ with this readout scheme. We have characterized the system-level performance of a 128-qubit readout system and have measured a readout error probability of $8\times10^{-5}$ in the presence of optimal latching element bias conditions.Comment: Updated for clarity, final versio
