Washing True poison-dart frogs (Phyllobates, Dendrobatidae) evolved the ability to secrete batrachotoxins, the most powerful alkaloids known to date.The genus comprises five species whose systematics, at first glance, appeared clear.The most derived clade would include two Colombian species (P.terribilis and P.bicolor) with the highest toxicity, th
We provide a detailed description of the path-integral Monte Carlo worm algorithm used to exactly calculate the thermodynamics of Bose systems in the canonical ensemble.The algorithm is fully consistent with periodic boundary conditions, which are applied to simulate homogeneous phases of bulk systems, and it does not require any limitation in the
HIV-1 nucleocapsid protein (NC) is involved in the rearrangement of nucleic acids occurring in key steps of reverse transcription.The protein, through its two zinc fingers, interacts preferentially with unpaired guanines in single-stranded sequences.In mini-cTAR Shoes stem-loop, which corresponds to the top half of the cDNA copy of the transactivat
In this study, we investigate the potential of sea ice segmentation by C- and X-band multi-polarisation synthetic aperture radar (SAR) features during late summer.Five high-resolution satellite SAR scenes were recorded in the Fram Strait covering iceberg-fast first-year and old sea ice during a week with air temperatures varying around 0 °C.Sea
