Molecular evidence supports a genic capture resolution of the lek paradox

open access: yesNature Communications, 2019
The genic capture hypothesis, where sexually selected traits capture genetic variation in condition and the condition reflects genome-wide mutation load, stands to explain the presence of abundant genetic variation underlying sexually selected traits ...

Predicting Stream Nitrogen Concentration From Watershed Features Using Neural Networks [PDF]

open access: yes, 1999
The present work describes the development and validation of an artificial neural network (ANN) for the purpose of estimating inorganic and total nitrogen concentrations. The ANN approach has been developed and tested using 927 nonpoint source watersheds

Multiple paternity in a lek mating system: Females mate multiply when they choose inexperienced sires.

open access: yesJournal of Animal Ecology, 2019
Multiple mating by females is common and often driven by social constraints on female mate choice. However, females mate with multiple males even in systems without these social constraints and rates of multiple mating tend to be highly variable within ...

Biopharmaceutical classification of desloratadine – not all drugs are classified the easy way

open access: yesActa Pharmaceutica, 2020
The biopharmaceutical classification of drugs was designed as a basis for bio-waivers – a mechanism with the double ethical benefit of delivering new drug formulations to the market with less human testing and lower cost.

Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish [PDF]

open access: yes, 2013
Reduced male aggression towards different phenotypes generating negative frequency-dependent intrasexual selection has been suggested as a mechanism to facilitate the invasion and maintenance of novel phenotypes in a population.

Methyl eugenol regulates mating behavior in oriental fruit flies by enhancing lek attractiveness

open access: yesNational Science Review
Plant-produced volatiles play a pivotal role as mediators in complex interactions between insects and plants. Despite the widespread recognition that these compounds serve as cues for herbivorous insects to locate their preferred host plants, their ...

On the Stability and Degradation Pathways of Venetoclax under Stress Conditions

open access: yesPharmaceutics, 2020
Venetoclax is an orally bioavailable, B-cell lymphoma-2 (BCL-2) selective inhibitor, used for the treatment of various types of blood cancers, such as chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).

Secants of minuscule and cominuscule minimal orbits [PDF]

open access: yes, 2014
We study the geometry of the secant and tangential variety of a cominuscule and minuscule variety, e.g. a Grassmannian or a spinor variety. Using methods inspired by statistics we provide an explicit local isomorphism with a product of an affine space ...

Optimization of UPLC method for simultaneous determination of rosuvastatin and rosuvastatin degradation products

open access: yesActa Chimica Slovenica, 2017
An ultra-performance liquid chromatographic method for simultaneous determination of rosuvastatin and rosuvastatin degradation products was developed and optimized by using fractional factorial experimental design.

Spatio-temporal co-occurrence of alien and native molluscs : a modelling approach using physical-chemical predictors [PDF]

open access: yes, 2017
The invasion of alien species can have serious economic and ecological impacts. Ecologically, invasions often lead to an increased rate of native species replacement and decreased biodiversity.
