Full major-shell calculation for states that were degenerate in a single-j-shell calculation
, 2005 A full fp calculation is performed for states which were degenerate in a single-j-shell calculation in which isospin-zero two-body matrix elements were set to zero energy. Most of the splitting in a complete shell calculation (but not all) comes from the

Complete N f 2 $$ {N}_f^2 $$ contributions to four-loop pure-singlet splitting functions
Journal of High Energy PhysicsThe scale evolution of parton distributions is determined by universal splitting functions. As a milestone towards the computation of these functions to four-loop order in QCD, we compute all contributions to the pure-singlet quark-quark splitting ...

On regular splittings of an M-matrix
Linear Algebra and its Applications, 1989 Some results on regular splittings of M-matrices are proved. The study is motivated by a recent work of \textit{H. Schneider} [ibid. 58, 407-424 (1984; Zbl 0561.65020)]. It is shown, first, that if A is a nonsingular M-matrix and \(A=M-N\) is a regular splitting then this splitting is a graph compatible one, and if A is just an M-matrix but \(A=M-N ...

Analysis of a unidirectional composite containing broken fibers and matrix damage [PDF]
An analytical solution is developed for the determination of the stresses and displacements in a unidirectional fiber-reinforced composite containing an arbitrary number of broken fibers as well as longitudinal yielding and splitting of the matrix.

Doubly perturbed $S_3$ neutrinos and the $s_{13}$ mixing parameter
, 2010 We further study a predictive model for the masses and mixing matrix of three Majorana neutrinos. At zeroth order the model yielded degenerate neutrinos and a generalized ``tribimaximal" mixing matrix. At first order the mass splitting was incorporated

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys
Advanced Engineering Materials, EarlyView.Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
