The fully frustrated ladder - a quasi-1D geometrically spin one half Heisenberg model is non-integrable with local conserved quantities on rungs of the ladder, inducing fragmentation Hilbert space into sectors composed singlets and triplets rungs. We explore far-from-equilibrium dynamics this through entanglement entropy out-of-time-ordered correlators (OTOC). post-quench highly anomalous as it...

The paper considers the results of chemical and mineralogical analysis ceramics different times deposits clay raw materials Central Yakutia. 7 ceramic fragments were examined, a three Republic Sakha (Yakutia) was performed. Yakutia have composition, depending on deposit materials. studied can be used to recreate ancient technology ceramics. There is also prospect for use in industry. For more d...

Common beech is a shade-tolerant tree species that can adapt to varying light intensities at the level of whole plants, crown fragments, and individual leaves. The acclimation abilities morphological, physiological, biochemical characteristics leaves were experimentally determined in crowns for different levels availability. About 24% higher length, width, area about 35% thickness recorded sun ...

We have assessed the published predictions of the pathway of folding of the B domain of protein A, the pathway most studied by computer simulation. We analyzed the transition state for folding of the three-helix bundle protein, by using experimental Phi values on some 70 suitable mutants. Surprisingly, the third helix, which has the most stable alpha-helical structure as a peptide fragment, is ...

  Long-term complications of retained war fragments in the body are not completely known. Also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. We reviewed the literature on complication of retained war fragments and report o...

DNA fragments related to the cloudy catshark Scyliorhinus torazame L-gulono-gamma-lactone oxidase (GULO) cDNA were detected in a distant fish species. Although the Southern hybridization pattern was more distinct in species with active GULO, DNA fragments related to the GULO gene were also discovered in the common carp Cyprinus carpio. Additionally, in the common carp, inter-individual variatio...

For the 68Zn + 112Sn reaction Coulomb parameter Z1Z2 is equal to 1500 that close threshold value for appearance of quasifission process. It was found mass-energy distributions fragments differ significantly from those obtained in 36Ar 144Sm leading formation same composite system 180Hg at similar excitation energies about 50 MeV. In case with ions, mass distribution fissionlike has a wide two-h...

objective: endometriosis is a common disease in which the endometrial stroma and glands grow abnormally outside the uterine cavity. the establishment of animal models can be effective for determining the etiology of endometriosis. in this study we compare two endometriosis models using endometrial fragments and isolated cultured endometrial cells. methods: we obtained endometrial tissues that ...

The mol-ecule of the title compound, C16H13BrO3, is built of two approximately planar fragments, viz. 3-bromo-benzoate [maximum deviation = 0.055 (2) Å and 2-oxo-2-p-tolyl-ethyl [maximum deviation = 0.042 (2) Å], inclined by 46.51 (7)°. In the crystal, weak C-H⋯O hydrogen bonds and Br⋯Br contacts [3.6491 (7) Å] connect the mol-ecules into infinite layers parallel to (-221).

Collaborative systems are characterized by groups or communities jointly working to accomplish some organizational goal. Members of the communities must coordinate their efforts to ensure that such goals are met. Development of collaborative systems can be facilitated by identifying common aspects of such coordination and by constructing product method fragments that can be composed into workin...
