Asymmetric information, self-selection and pricing of insurance contracts: the simple no-claims case [PDF]
, 2013 This paper presents an optional bonus-malus contract based on a pri-ori risk classification of the underlying insurance contract. By inducing self-selection, the purchase of the bonus-malus contract can be used as a screening device.

Development of cisgenic apples with durable resistance to apple scab [PDF]
, 2009 Most of the apple (Malus × domestica) growers are facing serious disease problems with apple scab which is caused by the fungus Venturia inaequalis. Developing a resistant variety in apple through classical breeding is very slow and inefficient.

Microsatellite genotyping of apple (Malus × domestica Borkh.) genetic resources in the Netherlands: application in collection management and variety identification [PDF]
, 2010 A highly informative set of 16 microsatellite markers was used to fingerprint 695 apple accessions from eight Dutch collections. Among the total sample, 475 different genotypes were distinguished based on multi-locus microsatellite variation, revealing a

Ruin probabilities with dependence on the number of claims within a fixed time window [PDF]
, 2016 We analyse the ruin probabilities for a renewal insurance risk process with inter-arrival time distributions depending on the claims that arrived within a fixed (past) time window. This dependence could be explained through a regenerative structure.

Morphological Differentiation Between \u3ci\u3eAphis Spiraecola\u3c/i\u3e and \u3ci\u3eAphis Pomi\u3c/i\u3e (Homoptera: Aphididae) [PDF]
, 2017 Aphis pomi and Aphis spiraecola, are both found on agriculturally important hosts such as apple and pear, and in trap collections. Their morphological similarity makes identification difficult.
