Granulomatous slack skin: report of a case associated with Hodgkin's disease and a review of the literature.
1994
We report a case of granulomatous slack skin (GSS) associated with Hodgkin's disease, and review the literature on this entity. GSS, a variant of cutaneous T-cell lymphoma, clinically presents with erythematous patches in the flexures, which gradually transform into bulky, pendulous areas of skin. Histology shows an elastolytic granulomatous infiltrate, with atypical lymphoid cells, and occasional epidermotropism. As far as we are aware, 10 cases of GSS, including our patient, have been reported in detail. The male:female ratio of these cases is 9:1, and the age range 15-51 years. Five cases were associated with Hodgkin's disease, one with small lymphocytic lymphoma, and one developed cutan…
Software-Based EDF Message Scheduling on CAN Networks
2006
In this paper, a CAN-based communication system has been used to transmit data between different kinds of sensors and the drive control of an electrical vehicle. Software-based earliest deadline first (EDF) scheduling has been applied to order the data, making possible that more relevant measures meet with their delivery time and, discarding, if necessary, less relevant ones are discarded. The messages use their time-to-deadline as their priority level. With this mechanism, alongside with the discard of data that has lost its deadline, is it possible to deal with saturated that would require a bus utilization well above 100%.
"Alliance Portfolio Diversity, Organizational Slack, and Firm Financial Performance"
2014
We investigate how the availability of slack influences a firm’s ability to deal with alliance portfolio diversity. Alliances with diverse partners provide access to a broader pool of complementary...
Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid.
2012
Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related Amplified Fragment Length Polymorphism markers genetic variation and fitness to colonization history for all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex. Around 1970, D. incarnata suffered a severe bottleneck yet ultimately persisted and gradually spread throughout the spatially segregated dune slacks, aided…
Optimal Set Points Regulation of Distributed Generation Units in Micro-grids under Islanded Operation
2010
The present work studies the problem of optimizing the power production levels of dispersed generation units in islanded microgrids. The problem is intrinsically multi-objective with non linear objectives and constraints, thus the solution approach is based on evolutionary optimization and uses the Non dominated Sorting Genetic Algorithm II. The objectives are calculated based on the solution of the load flow problem. The latter problem is more complicated when in the considered system a physical node with a sufficiently large production capability is not available, because all the generation node of the systems have similar and limited generation capability. In this paper, the issue has be…
Energy efficiency in the European Union: What can be learned from the joint application of directional distance functions and slacks-based measures?
2014
Abstract Over the last few years concerns have increased about the energy mix in many countries. These concerns have been of greater magnitude for countries with a common energy regulation such as European Union (EU) member states. An important aspect to take into account when choosing a given energy mix is the efficiency involved in its generation. In this context, the present study analyzes the efficiency with which electricity and derived heat was produced in 25 EU member states over the last decade. This analysis considers not only the inputs and outputs involved but, more importantly, which undesirable by-products were generated during the production process, a relevant issue for EU cl…
Improvisation for innovation: The contingent role of resource and structural factors in explaining innovation capability
2018
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. This paper focuses on resource and structural factors to explore the relationship between organizational improvisation and innovation capability. Although the role of improvisation has attracted increasing academic attention in fast-changing environments, little is known about the conditions under which firms benefit from improvisation. This paper addresses this gap using an organizational learning perspective that explains the role of a firm's organizational structure and organizational resources for improvisation and innovation. A large-scale …
Alliance portfolio diversity, organizational slack, and firm performance
2013
In this paper we analyze whether and how the availability of internal resources in the form of slack influences a firm ability to deal with partner diversity in its alliance portfolio. Alliances with diverse partners provide access to a broader pool of complementary resources, but they also entail significant coordination costs. In this context, we argue that slack acts as a doubleedged sword that can either facilitate or hinder the management of interdependencies among different alliance projects. Accordingly, we further argue that the net impact of slack will depend on the firm’s experience in dealing with the challenges posed by portfolio diversity. Empirical analysis on a sample of firm…
