Phasing by molecular replacement remains difficult for targets that are far from the search model or in situations where the crystal diffracts only weakly or to low resolution. Here, the process of determining and refining the structure of Cgl1109, a putative succinyl-diaminopimelate desuccinylase from Corynebacterium glutamicum, at ∼3 Å resolution is described using a combination of homology m...
In this paper, we propose computational methods for the synthesis of controllers for discrete event systems modeled by polynomial dynamical systems over nite Galois eld. The control objectives are speciied as order relations to be checked and as minimization of a given cost function over the states through the trajectories of the system. The control objectives are then synthesized using algebra...
The family Rhabdoviridae is a diverse group of non-segmented, negative-sense RNA viruses that are distributed worldwide and infect a wide range of hosts including vertebrates, invertebrates, and plants. Of the 114 currently recognized vertebrate rhabdoviruses, relatively few have been well characterized at both the antigenic and genetic level; hence, the phylogenetic relationships between many ...
Some species of birds react to climate change by reducing the distance they travel during migration. The Odra River Estuary in the Baltic Sea is important for wintering waterfowl and is where we investigated how waterbirds respond to freezing surface waters. The most abundant birds here comprise two ecological groups: bottom-feeders and piscivores. Numbers of all bottom-feeders, but not piscivo...
Background. Morphological characterization of hemodialysis membranes is necessary to improve pore design. Aim. To delineate membrane pore structure of a high flux filter, Polyflux 210H. Methods. We used a Joel JSM-6010LV scanning electron microscope (SEM) and a SU6600 Hitachi field emission scanning electron microscope (FESEM) to characterize the pore and fiber morphology. The maximal diameters...
The refinement and validation of a crystallographic structure model is the last step before the coordinates and the associated data are submitted to the Protein Data Bank (PDB). The success of the refinement procedure is typically assessed by validating the models against geometrical criteria and the diffraction data, and is an important step in ensuring the quality of the PDB public archive [R...
attention to interesting aspects of natural history. In most of my research projects I try to reserve a little bit of time for taking photographs. Our projects on waterbirds are ideal for combining data collection with a bit of photography — we observe our focal broods from floating, mobile blinds, in wetlands teeming with waterbirds. With a really good blind, it’s like being invisible — we oft...
