Models of sexual selection assume that female mating preferences are heritable and, thus, repeatable for individual females across multiple mating episodes. Previous studies of the repeatability of female preference have examined individuals in captivity and focused presumably on social mate choice. However, extra-pair mating is widespread and can also influence sexual selection. We examined th...

This paper describes structural polymorphism, a new form of type polymorphism appropriate to functional languages featuring user-defined algebraic data types (e.g., Standard ML, Haskell and Miranda1). The approach extends the familiar notion of parametric polymorphism by allowing the definition of functions which are generic with respect to data structures as well as to individual types. For ex...

Selections of the proximal-distal axis were removed so as to produce wings lacking entire skeletal levels. The innervation of the resulting limb from the appropriate spinal nerves was tested by electrophysiological recording, gross dissection and serial sections. Ther nerves form repeatable and ordered patterns in the modified limbs which can be readily related to the normal pattern. In general...

In order to analyze the functions of the hippocampus in the primate, and to advance the understanding of amnesia, the activity of 994 single hippocampal neurons in the monkey was analyzed during the performance of a task known to be affected by hippocampal damage in which both an object, and its position in space, must be remembered. The serial multiple object-place memory task required a memor...

In this work we address the use of realtime cortical recordings for the generation of coherent, reliable and robust motor activity in spinal-lesioned animals through selective intraspinal microstimulation (ISMS). The spinal cord of adult rats was hemisectioned and groups of multielectrodes were implanted in both the central nervous system (CNS) and the spinal cord below the lesion level to esta...

in order to study the genetic diversity of the causal agent of fusarium wilting in chickpea, two techniques including rapd and pcr-rflp were used. in rapd-pcr technique, all 14 primers could show the diversity among the isolates. after studding the banding patterns of 14 primers, a dendrogram based on similarity matrix was constructed. the rapd dendrogram analysis could not separate isolates ba...

Aspect-oriented programming (AOP) has been shown to be a useful model for software development. Special care must be taken when we try to adapt AOP to strongly typed functional languages which come with features like type inference mechanism, polymorphic types, higher-order functions and type-scoped pointcuts. Specifically, it is highly desirable that weaving of aspect-oriented functional progr...
