19. Hyperpigmentation and atrophy in folds as cutaneous manifestation in a case of mitochondrial myopathy

Author

Campuzano-Garcia, Andres Eduardo, Rodriguez-Arambula, Adriana, Torres-Alvarez, Bertha, and Castanedo-Casares, Juan Pablo

Abstract

Mitochondrial myopathies are inborn metabolism defect diseases manifested by symptoms reflecting failure of the final step in the mitochondrial respiratory chain. Clinical expression of these conditions can vary widely, but typically includes organ systems with a high energy demand, such as striated muscle, myocardium, and nervous and liver tissues. In contrast, cutaneous manifestations are rare and are non-specific, most commonly presenting as pigmentation disorders. In this case report, we present a case of Alpers syndrome accompanied by hyperpigmentation and atrophy in skin folds.

22. A Multi-View Intelligent Editor for Digital Video Libraries.

Author

Myers, Brad A., Casares, Juan P., Stevens, Scott, Dabbish, Laura, Yocum, Dan, and Corbett, Albert

Abstract

Digital video is becoming increasingly ubiquitous. Most camcorders today are digital, and computers are being advertised based on their video editing capabilities. Many exciting research projects are investigating how to search, visualize, and summarize digital video, but there is little work on new ways to support the use of the video beyond just playing it. In fact, editing video is significantly more difficult than editing textual material. Silver (Simplifying Interactive Layout and Video Editing and Reuse) is an authoring tool that aims to allow novice users to edit digital video. The goal is to make editing of digital video as easy as text editing. Silver provides multiple coordinated views, including project, source, outline, subject, storyboard, textual transcript and timeline views. Selections and edits in any view are synchronized with all other views. A variety of recognition algorithms are applied to the video and audio content and then are used to aid in the editing tasks. The Informedia Digital Library supplies the recognition algorithms and metadata used to support intelligent editing, and Informedia also provides search and a repository. The metadata includes shot boundaries and a time-synchronized transcript, which are used to support intelligent selection and intelligent cut/copy/paste. (Contains 35 references.) (Author/AEF)

39. 2D self-assembly of o-OPE foldamers for chiroptical barcoding

Abstract

We report on the preparation and characterization of two dimensional (2D) films of (S,S,P)-1 and (R,R,M)-1ortho-oligophenylene ethylene (o-OPE) enantiomers presenting high values of circularly polarized luminescence (CPL). The amphiphilic character of these two molecules allows a precise 2D self-assembly at the air/water interface and an efficient transfer onto a glass solid support. The morphological and chiroptical characterization of the solid supports after the transfer of 1, 8, 16 and 32 Langmuir films of (S,S,P)-1 and (R,R,M)-1 has been carried out. The strong chiroptical values of these monomers allow reliable ECD measurements to be obtained after a single transfer, with ECD values increasing as the number of transferred films increases. The semi-liquid behavior of the monomers on the solid substrate allows CPL measurements free of photoselection artifacts that show values similar to those obtained in solution and independent of monomer concentration. All these properties have allowed us to develop the first simple organic molecule (SOM)-based chiroptical barcoding presenting positive and negative regions as a proof of concept.

Abstract

Fabrication of electrodes for polymer electrolyte fuel cells is a intriguing process in which a balance between gas transport, electrical conductivity, proton transport and water managing must be optimized. In this work four different electrodes prepared by electrospray deposition have been studied using different catalytic inks, in which Nafion and epoxy doped with Graphene-Nanoplatelets were used as binders. After studying the behavior of those electrodes in a single open cathode fuel cell proton electrolyte membrane, it is clear that the addition of epoxy as binder doped with graphene, improves the performance of the fuel cell and increase the mechanical stability of the electrode avoiding the loose of catalyst during the electrode manipulation in the fuel cell assembly process and the durability of the fuel cell. To explain this behavior, an ex-situ study was carried out, in which properties such as its surface morphology, hydrophobicity and electrical and thermal conductivity of those electrodes were studied. From the results of this study, such improvement in the performance of the fuel cell was justified on the basis of the increase in the electrical conductivity, a diminution in its thermal conductivity and an enhancement of hydrophobicity (surface morphology) of the deposited catalyst layer, when an optimum quantity of epoxy is added to the catalytic ink that makes to improve the mechanical properties of those electrodes

50. Climate Change and Resilient Rail Freight Transport

Abstract

Rail freight transport is a key economic activity; many businesses and people rely on it. It should be available when needed and efficient in use. There are however factors that may reduce the availability and quality of a rail freight service offering. A distinction can be made between what may be called systemic factors, like congestion, accidents and technical failures, and external factors like weather conditions and natural disasters. Rail infrastructure managers and users of rail services have learned from experience to anticipate or adapt to systemic factors. They are, to some extent, also able to cope with certain weather conditions. A rather different situation occurs when the weather becomes more extreme and less predictable. Water management systems are usually not developed for excess amounts of rain and hence will fail. Terrestrial water can turn into a devastating flood that may (temporarily) incapacitate railway infrastructure. With this (partially) out of service, freight trains have to be rerouted. This may lead to severe delays, additional costs and externalities, in particular more emissions. This paper deals with the question: What are options for governments to make rail freight transport more resilient to disruptions triggered by climate change, while limiting the externalities caused by rerouting? The paper is an extension of earlier research on this topic. Methods used in the research were a case study, the data of which were fed into a simulation model, which was used to estimate route length, fuel consumption and emissions. The main outcome of the study is that there are interesting options to make rail freight transport networks more resilient. In order to reap their benefits, interoperability should be improved considerably.
