The eleven papers in this special issue analyze how different sources of disruption collide with normality, the consequences on individual, social and institutional life, efforts to re-establish old or create a new normal. They arose from series online seminars September October 2020 investigating normalization wake current environmental, technological, epidemiological socio-economic shocks. Di...

Landmarks play an important role when humans navigate through foreign environments (Lynch, 1960; May, Ross, Bayer, and Tarkiainen, 2003). For example, trying to find the way is much easier if the navigator can rely on a description of the route based on well-recognizable objects in the environment, instead of navigating solely on the basis of street names and metric directions (Tom, and Denis, ...

Insects face the challenge of navigating to specific goals in both bright sun-lit and dim-lit environments. Both diurnal and nocturnal insects use quite similar navigation strategies. This is despite the signal-to-noise ratio of the navigational cues being poor at low light conditions. To better understand the evolution of nocturnal life, we investigated the navigational efficiency of a nocturn...

7-140. nts perceive in Abstract. Route directions are instructions, primarily verbal, that explain how to get from one place to another. The current study examines several methods for assessing the quality of verbal route directions by characterizing them in terms of the number of elements (such as landmarks, segments or turns) and by subjective ratings of their goodness. Route directions for r...

Recovering the shape of a class of objects requires establishing correct correspondences between manually or automatically annotated landmark points. In this study, we utilise a novel approach to automatically recover the shape of hand outlines from a series of 2D training images. Automated landmark extraction is accomplished through the use of the self-organising model the growing neural gas (...

We present a simple artificial landmark model and a robust landmark tracking algorithm for mobile robot localization. The landmark model, consisting of symmetric and repetitive color patches, produces color histograms that are invariant under the geometric and photometric distortions. A stochastic approach based on the CONDENSATION tracks the landmark model robustly even under the varying illum...

allogeneic hematopoietic stem cell transplantation (hsct) is the most effective therapy to prevent relapse in acute lymphocytic leukemia (all). this benefit is affected by non-relapse mortality (nrm) due to complications such as graft versus host disease (gvhd). a new approach in analyzing time-dependent covariates in competing risks is landmark analysis. so, the aim of this study is to evaluat...
