Chemistry – A European Journal, EarlyView.A compact C4N4 fluorophore—comprising only four carbons and four nitrogens—shows structure‐dependent fluorescence that can be rationalized by TDDFT and AFIR analyses. Rational structural design controls whether emission is turned ON or OFF through computationally identified CI structures.

Chemistry – A European Journal, EarlyView.An iridium‐catalyzed linear‐selective sp3 C─H alkylation of N‐methylamides with alkenes is described. This method tolerates various N‐methylacetamide derivatives and has a broad alkene scope. Mechanistic studies were also conducted. Internal alkenes can also be used through in situ consecutive alkene isomerization.

Vibro-Acoustic FE Analyses of the Saab 2000 Aircraft [PDF]
A finite element model of the Saab 2000 fuselage structure and interior cavity has been created in order to compute the noise level in the passenger cabin due to propeller noise.

Chemistry – A European Journal, EarlyView.Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.

Finite element substructuring methods for composite mechanics [PDF]
Finite element substructuring strategies are presented to obtain numerical solutions for three typical problems of interest to the composites community: (1) impact and toughness characterization of composites using Charpy's impact test specimen; (2) free-

Cytoskeleton, EarlyView.ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Three-dimensional analysis of a postbuckled embedded delamination [PDF]
Delamination growth caused by local buckling of a delaminated group of plies was investigated. Delamination growth was assumed to be governed by the strain energy release rates, G(1), G(2) and G(3). The strain energy release rates were calculated using a

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near
