Burkholderia semiarida has only been reported as a plant pathogen causing onion sour skin (1). The Burkholderia genus encompasses >120 bacterial species that are typically reported to inhabit soil and [...]

Within the thermodynamic framework with internal variables, the classical Hamilton’s principle for elastic bodies is extended to inelastic bodies composed of materials whose free energy densities are point functions of internal variables, or the so‑termed Green-inelastic bodies, subject to finite deformation and non-conservative external forces. Yet this general result holds true even without the Green-inelasticity presumption under a more general interpretation of the infinitesimal internal rearrangement. Three special cases are discussed following the generalized form: (a) the Green-elastic bodies whose free energy can be identified with the strain energy; (b) the Green-inelastic bodies composed of materials compliant with the additive decomposition of strain; and (c) the Green-inelastic bodies undergoing isothermal relaxation processes where the thermodynamic forces conjugate to internal variables, or the so-termed internal forces prove to be potential forces. This paper can be viewed as an extension of Yang et al. [1].

An S-doped CdO@In2O3 nanofiber was successfully designed by in-situ electrospinning along and subsequent calcination treatment. Under artificial sunlight illumination, the S/CdO@In2O3-25 displayed a superior photocatalytic hydrogen evolution rate of 4564.58 μmol·g−1·h−1, with approximately 22.0 and 1261.0-fold of those shown by the S/CdO and S/In2O3 samples, respectively. The experimental and theoretical analyses illustrate that the unique one-dimensional (1D) nanofiber morphology and rich oxygen vacancies optimized the electronic structure of the nanofibers and adsorption/desorption behaviors of reaction intermediates, contributing to the realization of the remarkable solar-to-H2 conversion efficiencies. Moreover, the staggered band structure and intimate contact heterointerfaces facilitate the formation of a type-II double charge-transfer pathway, promoting the spatial separation of photoexcited charge carriers. These results could inform the design of other advanced catalyst materials for photocatalytic reactions. [ABSTRACT FROM AUTHOR]

Here, we report a completely sequenced plastome using Illumina/Solexa sequencing-by-synthesis (SBS) technology. The plastome of Magnolia kwangsiensis Figlar & Noot. is 159 667 bp in length with a typical quadripartite structure: 88 030 bp large single-copy (LSC) and 18 669 bp small single-copy (SSC) regions, separated by two 26 484 bp inverted repeat (IR) regions. The overall predicted gene number is 129, among which 17 genes are duplicated in IR regions. The plastome of M. kwangsiensis is identical in its gene order to previously published plastomes of magnoliids. Furthermore, the C-to-U type RNA editing frequency of 114 seed plants is positively correlated with plastome GC content and plastome length, whereas plastome length is not correlated with GC content. A total of 16 potential putative barcoding or low taxonomic level phylogenetic study markers in Magnoliaceae were detected by comparing the coding and noncoding regions of the plastome of M. kwangsiensis with that of Liriodendron tulipifera L. At least eight markers might be applied not only to Magnoliaceae but also to other taxa. The 86 mononucleotide cpSSRs that distributed in single-copy noncoding regions are highly valuable to study population genetics and conservation genetics of this endangered rare species. Key words: Magnolia kwangsiensis, plastome, DNA barcoding, cpSSR, RNA editing. Les auteurs rapportent une sequence complete du plastome obtenue grace a la technologie SBS sur appareil Illumina/Solexa. Le plastome du Magnolia kwangsiensis totalise 159 667 pb et presente une structure quadripartite typique : une region LSC de 88 030 pb et une region SSC de 18 669 pb, ces dernieres etant separees par deux regions IR de 26 484 pb. Le nombre de genes predits s'etablit a 129, dont 17 sont dupliques au sein des IR. L'ordre des genes au sein du plastome du M. kwangsiensis est identique a celui des plastomes publies anterieurement chez d'autres Magnoliidees. De plus, la frequence de l' edition des ARN de type C vers U chez 114 angiospermes est correlee positivement avec le contenu en GC. Seize sequences potentiellement utiles a titre de codes barres ou comme marqueurs pour des etudes phylogenetiques a des niveaux taxonomiques inferieurs chez les Magnoliacees ont ete identifiees en comparant les regions codantes et noncodantes du plastome du M. kwangsiensis avec celles du Liriodendron tulipifera. Au moins huit d'entre elles pourraient etre employees chez les Magnoliacees, mais aussi chez d'autres taxons. Les 86 microsatellites mononucleotidiques (cpSSR) distribues au sein des regions non-codantes a simple copie sont tres utiles pour etudier la genetique des populations et pour des fins de conservation chez cette espece rare menacee.

Fabric tensor has proved to be an effective tool statistically characterizing directional data in a smooth and frame-indifferent form. Directional data arising from microscopic physics and mechanics can be summed up as tensor-valued orientation distribution functions (ODFs). Two characterizations of the tensor-valued ODFs are proposed, using the asymmetric and symmetric fabric tensors respectively. The later proves to be nonconvergent and less accurate but still an available solution for where fabric tensors are required in full symmetry. Analytic solutions of the two types of fabric tensors characterizing centrosymmetric and anticentrosymmetric tensor-valued ODFs are presented in terms of orthogonal irreducible decompositions in both two- and three-dimensional (2D and 3D) spaces. Accuracy analysis is performed on normally distributed random ODFs to evaluate the approximation quality of the two characterizations, where fabric tensors of higher orders are employed. It is shown that the fitness is dominated by the dispersion degree of the original ODFs rather than the orders of fabric tensors. One application of tensor-valued ODF and fabric tensor in continuum damage mechanics is presented.
