This paper describes the use of a genetic algorithm (GA) to find optimal parameter-values for trading agents that operate in virtual online auction ‘e-marketplaces’, where the rules of those marketplaces are also under simultaneous control of the GA. The aim is to use the GA to automatically design new mechanisms for agent-based e-marketplaces that are more efficient than online markets designe...

The critical study of political discourse has up until very recently rested solely within the domain of the social sciences. Working within a linguistics framework, Critical Discourse Analysis (CDA), in particular Fairclough (Fairclough 1989, 1995a, 1995b, 2001; Fairclough and Wodak 1997), has been heavily influenced by Foucault. 2 The linguistic theory that CDA and critical linguistics especia...

We have read with interest the observational study by Mahfouz and colleagues (1), who examined the role of cytidine deaminase (CDA) on outcomes of patients treated with 5-azacytidine or decitabine. Surprisingly, gender emerged as themain determinant of CDA levels, and consequently, male patients displayed worse outcome as compared with females. These data donotmatch the results of all previous ...

This article presents empirical tests to examine if the comprehensive development area (CDA) where the town planning is more comprehensive has relatively higher economic values than the area outside CDA. The three hypothesis are: (i) CDAs have less environmental complaints than areas outside CDA; (ii) property sales price variances in CDAs are smaller than those in areas outside CDAs; and (iii)...

The persistence of cellulose diacetate (CDA), a biobased plastic used in textiles and single-use consumer products, the ocean is currently unknown. Here, we probe disintegration degradation CDA-based materials (25 μm films, 510 foam, 97 g/m2 fabric) by marine microbes continuous flow seawater mesocosm. Photographic evidence mass loss measurements demonstrate that disintegrate months. Disintegra...

Abstract Objectives Near-infrared (NIR) spectroscopy is a rapid technique able to assess meat quality even if its capability determine the shelf life of chicken fresh cuts still debated, especially for portable devices. The aim study was compare bench-top and NIR instruments in discriminating between four breast refrigeration times (RT), coupled with multivariate classifier models. Materials Me...

The present study investigated the development of visuospatial working memory (VSWM) capacity and the efficiency of filtering in VSWM in adolescence. To this end, a group of IQ-matched adults and adolescents performed a VSWM change detection task with manipulations of WM-load and distraction, while performance and electrophysiological contralateral delay activity (CDA) were measured. The CDA is...

PURPOSE OF REVIEW Congenital dyserythropoietic anemias (CDAs) are rare hereditary disorders characterized by ineffective erythropoiesis and by distinct morphological abnormalities of erythroblasts in the bone marrow. Characteristic morphological aberrations were the cornerstone of diagnosis, but following the identification of several causative genes, the molecular approach could represent a ra...

Studies have been conducted with the arginase (l-arginine amidinohydrolase, EC 3.5.3.1) of two legumes: jack bean, Canavalia ensiformis (L.) DC., a l-canavanine-containing plant and soybean, Glycine max, a canavanine-free species. Analyses of the arginase obtained from gradient-purified mitochondria of these legumes revealed that the arginine-dependent (ADA) and canavanine-dependent activities ...

We evaluated the influence of amifostine used alone or in combination with 2-chlorodeoxyadenosine (2-CdA) on the colony growth of normal and chronic myeloid leukemia (CML) granulocyte-macrophage progenitor cells (CFU-GM) in semisolid culture in vitro. Amifostine at a concentration of 1 mg/ml was either added directly to the culture medium of normal and CML CFU-GM, or mononuclear cells (MNCs) we...
