Migrant bird populations often show substantial variation in route choice and timing. Determining whether this population-level is driven by between-individual differences and/or flexibility within individuals key to identifying drivers of migration patterns. ‘Repeatability' (R, the proportion attributable variation) has become a central metric for relative consistency individual behaviour. Ind...

DNA base composition is a fundamental genome feature. However, the evolutionary pattern of base composition and its potential causes have not been well understood. Here, we report findings from comparative analysis of base composition at the whole-genome level across 2210 species, the polymorphic-site level across eight population comparison sets, and the mutation-site level in 12 mutation-trac...

background: classification of molar gestation into complete hydatidiform mole (chm) and partial hydatidiform mole (phm) is done according to clinical, ultrasonographic, histologic and genetic criteria. however, making a distinction between chm and phm using histologic criteria alone may be difficult and several studies have shown that misclassifications are frequent, even for experienced pathol...

Cocrystal formation rates during dry grinding and liquid-assisted grinding were investigated by X-ray powder diffractometry and Raman spectroscopy. Two polymorphic forms of piracetam were used to prepare known piracetam cocrystals as model substances, i.e.,piracetam-citric acid and piracetam-tartaric acid cocrystals. Raman spectroscopy in combination with principal component analysis was used t...

ATRIA, M. & VAN WELZEN, P. C. 2021. The Calamus javensis (Arecaceae: Calamoideae) complex in historical biogeographic context. Reinwardtia 20(1): 1−7. — is a very polymorphic species with number of recognisable forms (of which several were once even recognized at level). A analysis showed no distribution pattern the diversification these various forms. are likely result adaptation to local ...

Capture-mark-recapture (CMR) approaches are the backbone of many studies in population ecology to gain insight on the life cycle, migration, habitat use, and demography of target species. The reliable and repeatable recognition of an individual throughout its lifetime is the basic requirement of a CMR study. Although invasive techniques are available to mark individuals permanently, noninvasive...

The value of polymorphism in programming languages has been demonstrated by languages such as ML [19]. Recent e cient implementations of ML have shown that a language with implicit polymorphism can be practical [1]. The core of ML's type system is limited, however, by the fact that only instances of polymorphic functions may be passed as arguments to other functions, but not the polymorphic fun...

Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...

Error motion trajectory data are routinely collected on multi-axis machine tools to assess their operational state. There is a wealth of literature devoted advances in modelling, identification and correction using such data, as well the collection processing alternative streams for purpose tool condition monitoring. Until recently, there has been minimal focus combining these two related field...
