Dissecting Colistin Resistance Mechanisms in Extensively Drug-Resistant Acinetobacter baumannii Clinical Isolates

open access: yesmBio, 2019
Nosocomial infections with Acinetobacter baumannii are a global problem in intensive care units with high mortality rates. Increasing resistance to first- and second-line antibiotics has forced the use of colistin as last-resort treatment, and increasing

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS Open Bio, Volume 16, Issue 3, Page 503-519, March 2026.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

INFLUENCE OF THE SIZE OF INCLUSIONS ON THE THRESHOLD OF EXPLOSIVE DECOMPOSITION OF MIXTURE COMPOSITIONS ON THE BASIS OF PETN (PENTAERYTHRITYL TETRANITRATE) AND INCLUSIONS OF Ni AND Al UNDER LASER INFLUENCE

open access: yesВестник Кемеровского государственного университета, 2014
The paper reveals the dependence of the probability of explosion of PETN with inclusions of nickel and aluminum in two sizes in samples on the density of energy of the initiating laser impulse (1064 nm, 14 ns).

Slit tube responses and rock fracture characteristics in slit charge blasting under high in situ stress

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 81-95, March 2026.
In this article, the finite element method‐smoothed particle hydrodynamics adaptive coupling algorithm is applied to numerically simulate and analyze the dynamic response of the slit tube and the crack propagation under high in situ stress. The dynamic response of the slit tube mainly exhibits radial response in the vertical direction of the slit and ...

Carya luodianensis (Juglandaceae), a New Species From Guizhou Province, Southern China, Revealed by Morphological and Plastid Evidence

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Carya luodianensis (Juglandaceae), a new species, is described and illustrated. We combined morphological characteristics, comparative plastome analyses, and phylogenetic analysis, all of which support the recognition of C. luodianensis as a new species and highlight its evolutionary divergence within Carya. ABSTRACT Carya luodianensis Y.B. Yang & M.T.

ReaxFF-lg: Correction of the ReaxFF Reactive Force Field for London Dispersion, with Applications to the Equations of State for Energetic Materials [PDF]

open access: yes, 2011
The practical levels of density functional theory (DFT) for solids (LDA, PBE, PW91, B3LYP) are well-known not to account adequately for the London dispersion (van der Waals attraction) so important in molecular solids, leading to equilibrium volumes for
