It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as dispersers. See...

We study the average-case running-time of single-source shortest-path (SSSP) algorithms assuming arbitrary directed graphs with n nodes, m edges, and independent random edge weights uniformly distributed in [0,1]. We give the first label-setting and label-correcting alg...

Proteolysis of hen egg-white lysozyme by thermolysin in 50% aqueous trifluoroethanol for 6–24 h at 40–52 °C produces a ‘nicked’ protein species which was purified to homogeneity by reverse-phase HPLC and characterized. Protein chemistry analytical methods were used to e...

a b s t r a c t Several multi-year biodiversity experiments have shown positive species richness-productivity rela- tionships which strengthen over time, but the mechanisms which control productivity are not well understood. We used experimental grasslands (Jena Experim...

In this paper we introduce a calibration procedure for validating of agent based models. Starting from the well-known financial model of (Brock and Hommes, 1998), we show how an appropriate calibration enables the model to describe price time series. We formulate the ca...

Treat), or a combination of both types. The choice of the most suitable technique is a difficult task, since various aspects must be taken into consideration. In this paper, we present a framework for evaluating barriers in terms of effectiveness and efficiency, along w...

Many psychological factors influence the onset and prognosis of heart disease, among the most studied, there are personality traits, depressive and anxious experiences. Type D personality, characterized by high levels of social inhibition and negative affectivity, is as...

Background The “halo sign” is considered the well known qualitative ultrasound (US) finding for the diagnosis of giant cell arteritis (GCA). Recently, the measurement of the intima-media thickness (IMT) of temporal and axillary arteries has been proposed as a potential ...

The effect of a diet based on former food products (FFP) as alternative feed ingredients on in vitro and in vivo digestibility of dry matter (DM), pig growth performance, and selected plasma bioche...

International audience; We described an efficient in situ generation of hydroxypyruvate from d‐serine catalyzed by a d‐amino acid oxidase from Rhodotorula gracilis. This strategy revealed an interesting alternative to the conventional chemical synthesis of hydroxypyruva...
