Selection of an ensemble of equally prepared quantum systems, based on measurements on it, is a basic step in quantum state purification. For an ensemble of single qubits, iterative application of selective dynamics has been shown to lead to complex chaos, which is a novel form of quantum chaos with true sensitivity to the initial conditions. The Julia set of initial valuse with no convergence ...

The chemical synthesis of backbone deuterium labelled [r(CGCGAAU*U*CGCG)]2 (U* = [5'-2H]U) is described. An efficient purification procedure was developed using a polymeric reverse phase (PRP) HPLC column at 60 degrees C. This procedure provided pure RNA dodecamer in the multi-milligram quantities (39% overall yield) necessary for dynamics studies using solid-state deuterium NMR. The purificati...

The addition of posttranslational modifications (PTMs) to proteins is an influential mechanism to temporally control protein function and ultimately regulate entire cellular processes. Most PTMs are present at low stoichiometry and abundance, which limits their detection when analyzing whole cell lysates. PTM purification methods are thus required to comprehensively characterize the presence an...

The asymmetric unit of the title compound, [Ni(2)(C(8)H(6)O(8))(C(12)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains a half of the centrosymmetric dinuclear complex mol-ecule and three uncoordinated water mol-ecules. In the dinuclear mol-ecule, two Ni(II) cations are bridged by the butane-1,2,3,4-tetra-carboxyl-ate (BTC(4-)) anion. Each Ni(II) atom is coordinated by two N atoms from the 1,10-phenanthr...

When a quantum system initialized in product state is subjected to either coherent or incoherent dynamics, the entropy of any its connected partitions generically increases as function time, signalling inevitable spreading (quantum) information throughout system. Here, we show that, presence continuous symmetries and under ubiquitous experimental conditions, symmetry-resolved inhibited due comp...

The bacterial population dynamics in an industrial scale reverse-osmosis (RO) water purification system were analyzed by fluorescent staining methods and denaturing gradient gel electrophoresis (DGGE). Bacterial numbers increased with storage in a tank, and bacterial diversity changed during the water purification process. A DNA sequence-based analysis of the major bands on the DGGE gel reveale...

Affinity purification in combination with isotope labeling of proteins has proven to be a powerful method to discriminate specific from nonspecific interactors. However, in the standard SILAC (stable isotope labeling by amino acids in cell culture) approach dynamic components may easily be assigned as nonspecific. We compared two affinity purification protocols, which in combination revealed in...
