Genotype by environment interactions (GEI) play a major part in shaping the genetic architecture of quantitative traits and are confounding factors in genetic studies, for example, in attempts to associate genetic variation with disease susceptibility. It is generally not known what proportion of phenotypic variation is due to GEI and how many and which genes contribute to GEI. Behaviors are co...

Computing equilibria in general equilibria models with incomplete asset (GEI) markets is technically difficult. The standard numerical methods for computing these equilibria are based on homotopy methods. Despite recent advances in computational economics, much more can be done to enlarge the catalog of techniques for computing GEI equilibria. This paper presents an interior point algorithm tha...

We add inside and outside money to the standard GEI model. If there enough gains to trade via money, then monetary equilibrium (ME) exists and money has positive value, even when GEI fails to exist. The nonexistence of GEI shows up as a liquidity trap in terms of the ME. In sharp contrast to GEI, the ME are generically determinate not only in terms of real, but also financial, variables. © 2003...

Microarray data from this article have been deposited with the NIH GEO Data Base under accession number GSE15147 ABSTRACT Understanding complex genotype-by-environment interactions (GEI) is crucial for understanding phenotypic variation. An important factor often overlooked in GEI studies is time. We measured the contribution of GEI to expression variation in 4 non-laboratory S. cerevisiae stra...

NCoR and SMRT are two paralogous vertebrate proteins that function as corepressors with unliganded nuclear receptors. Although C. elegans has a large number of nuclear receptors, orthologues of the corepressors NCoR and SMRT have not unambiguously been identified in Drosophila or C. elegans. Here, we identify GEI-8 as the closest homologue of NCoR and SMRT in C. elegans and demonstrate that GEI...

This paper introduces a new approach for gait analysis based on the Gait Energy Image (GEI). The main idea is to segment the gait cycle into some biomechanical poses, and to compute a particular GEI for each pose. Pose-based GEIs can better represent body parts and dynamics descriptors with respect to the usually blurred depiction provided by a general GEI. Gait classification is carried out by...

This paper presents results from the analysis of user interactions in the GEI (German Education Index) specialised search engine. The main interest of this study is getting insights into the GEI users’ typical search behaviour to identify optimisation potential for the further development of the GEI search engine. Based on a sample of query logfiles, the study has revealed that the users apply ...

Apart from human recognition, gait has lately become a promising biometric feature also useful for prediction of gender. One of the most popular methods to represent gait is the well-known Gait Energy Image (GEI), which conducts to a high-dimensional Euclidean space where many features are irrelevant. In this paper, the problem of selecting the most relevant GEI features for gender classificati...

Understanding complex genotype-by-environment interactions (GEIs) is crucial for understanding phenotypic variation. An important factor often overlooked in GEI studies is time. We measured the contribution of GEIs to expression variation in four nonlaboratory Saccharomyces cerevisiae strains responding dynamically to a 25 degrees -37 degrees heat shock. GEI was a major force explaining express...

A 4-month-old, intact male domestic short-hair cat was presented to Veterinary Hospital with an acuteonset of regurgitation and respiratory distress. Thoracic and abdominal radiographs identified a massconsisted of a heterogeneous mixture of soft tissue and gas densities between heart and craniodorsal part of the diaphragm that was shifted to the left. The stomach could not be seen clearly. Rad...
