ChemistryEurope, EarlyView.The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

A Krull-Schmdit type theorem for coherent sheaves
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 Let X be projective variety over an algebraically closed field k and G be a finite group with g.c.d.(char(k), |G|) = 1. We prove that any representations of G on a coherent sheaf, ρ : G → End(ℰ), has a natural decomposition ℰ ≃ ⊕ V ⊗k ℱV, where G acts ...

Chemistry – A European Journal, EarlyView.ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

A Markov approach to credit rating migration conditional on economic states
Canadian Journal of Statistics, EarlyView.Abstract We develop a model for credit rating migration that accounts for the impact of economic state fluctuations on default probabilities. The joint process for the economic state and the rating is modelled as a time‐homogeneous Markov chain. While the rating process itself possesses the Markov property only under restrictive conditions, methods ...

Classification of irreducible based modules over the complex representation ring of $ S_4 $
AIMS MathematicsThe complex representation rings of finite groups are the fundamental class of fusion rings, categorified by the corresponding fusion categories of complex representations.

European Policy Analysis, EarlyView.ABSTRACT In response to renewed interest in analytical tools that address complex policy problems and move beyond linear‐rational approaches in policy appraisal, Social Multi‐Criteria Evaluation (SMCE) integrates participatory approaches with multi‐criteria analysis (MCA), thereby incorporating specialised knowledge and diverse social values and ...

Three point interaction of Dirac fermions with higher spin particles and discrete symmetries
Journal of High Energy PhysicsWe constructed all possible kinematically allowed three-point interactions of two massless Dirac spinors with massive higher-spin bosons. In any D spacetime, the interactions have been constructed using the projections of the higher spin irreducible ...

Fire and Materials, EarlyView.ABSTRACT This article examines a transient, one‐dimensional model of surface regression during opposed flow flame spread over finite thickness, non‐charring thermoplastics. Gas to solid conductive transfer from the flame drives sample heating. The solid degrades into volatile fuel molecules in two stages: (1) the pre‐vaporization heat‐up stage and (2 ...
