Pedigree Breeding: We created a backcross pedigree between the Belgian Waterslager (BWS) and Border canary strains (Supplementary Figure 1) using a breeding design similar to one previously used to analyze inheritance of song learning in the German Roller strain (Mundinger 1999). The male and female founder BWS canaries came from Holland and Belgium, respectively, and the Border stock from Engl...

This paper introduces Reciprocal Recommenders, an important class of personalised recommender systems that has received little attention until now. The applications of Reciprocal Recommenders include online systems that help users to nd a job, a mentor, a business partner or even a date. The contributions of this paper are the de nition of this class of recommendation system, the identi cation ...

BACKGROUND Our aim was to investigate the existence of a reciprocal relationship between patients' assessment of quality of life and their appraisal of health. If present, this relationship will interfere with the interpretation of heart surgery's effect on overall quality of life. METHODS Path analysis was used to investigate reciprocal causal relationships between general health perceptions...

O NE hundred seventy-nine ewe lambs from a three-breed polyallel cross involving the Willamette, Suffolk and Hampshire breeds were used to study the genetic aspects of fertility. Ewe birth weight, ewe weight at mating and fertility were analyzed in relation to heterosis, general combining ability, maternal effect, reciprocal differences, and the effects of a hormone treatment. Treatment consist...

BACKGROUND AND OBJECTIVES Workplace bullying has been classified as an extreme social stressor in work contexts and has been repeatedly linked to several negative consequences. However, little research has examined reversed or reciprocal relations of bullying and outcomes. DESIGN We conducted a two-wave longitudinal study with a time lag of six months. METHODS The study sample consisted of ...

Modular architecture is a hallmark of many brain circuits. In the cerebral cortex, in particular, it has been observed that reciprocal connections are often present between functionally interconnected areas that are hierarchically organized. We investigate the effect of reciprocal connections in a network of modules of simulated spiking neurons. The neural activity is recorded by means of virtu...

Cellular proteomes are thought to be optimized for function, leaving no room for proteome plasticity and, thus, evolution. However, hybrid animals that result from a viable cross of two different species harbor hybrid proteomes of unknown complexity. We charted the hybrid proteome of a viable cross between Drosophila melanogaster females and Drosophila simulans males with bottom-up proteomics. ...
