A Stringinspired Ansatz for Quark Masses and Mixing
, 1996
"... We propose a simple but realistic pattern of quark mass matrices at the string scale, which can be derived from orbifold models of superstring theory with no use of gauge symmetries. This pattern is leftright symmetric and preserves the structural parallelism between up and down quark sectors. Its ..."

We propose a simple but realistic pattern of quark mass matrices at the string scale, which can be derived from orbifold models of superstring theory with no use of gauge symmetries. This pattern is leftright symmetric and preserves the structural parallelism between up and down quark sectors. Its phenomenological consequences on flavor mixing and CP violation are confronted with current experiments at the weak scale by use of the renormalizationgroup equations in the framework of the minimal supersymmetric standard model. We find that good agreement is achievable without finetuning.
AtomicAccuracy Prediction of Protein Loop Structures through an RNAInspired Ansatz
"... Consistently predicting biopolymer structure at atomic resolution from sequence alone remains a difficult problem, even for small subsegments of large proteins. Such loop prediction challenges, which arise frequently in comparative modeling and protein design, can become intractable as loop lengths ..."

atom configurations. This article introduces an alternative modeling strategy based on a ‘stepwise ansatz’, recently developed for RNA modeling, which posits that any realistic allatom molecular conformation can be built up by residuebyresidue stepwise enumeration. When harnessed to a dynamic
BUTP96 A Quasimaximal mixing ansatz for neutrino oscillations.
, 1996
"... Inspired by the atmospheric multiGeV neutrino data, we consider neutrino flavor mixing matrices which are maximal in a 2 × 2 subsector. This condition is a strong restriction: the full matrix including complex phases depends essentially on one parameter. The survival probability is an universal fun ..."

Direct Reduction and Differential Constraints
, 1994
"... . Direct reductions of partial differential equations to systems of ordinary differential equations are in onetoone correspondence with compatible differential constraints. The differential constraint method is applied to prove that a parabolic evolution equation admits infinitely many characteris ..."

The classical Lie method for finding groupinvariant solutions, first described in full generality in [7], generalizes and includes wellknown methods for finding similarity solutions, travelling wave solutions, and other basic
SPhTT08/140 Topological expansion of the Bethe ansatz, and noncommutative algebraic geometry
, 809
"... In this article, we define a noncommutative deformation of the ”symplectic invariants ” (introduced in [13]) of an algebraic hyperelliptical plane curve. The necessary condition for our definition to make sense is a Bethe ansatz. The commutative limit reduces to the symplectic invariants, i.e. alge ..."

1 Deep inelastic Scattering, QCD, and generalised vector dominance ∗
, 1999
"... We provide a formulation of generalised vector dominance (GVD) for low– x deepinelastic scattering that explicitly incorporates the γ ∗ → q¯q transition and a QCDinspired ansatz for the (q¯q)p forwardscattering amplitude. The destructive interference originally introduced in offdiagonal GVD is r ..."

Integrable Impurity Model with Spin and Flavour: Model Inspired by Resonant Tunneling in Quantum Dot
, 1998
"... We introduce an integrable impurity model in which both electrons and impurity have spin and flavour degrees of freedom. This model is a generalization of the multichannel Kondo model and closely related with resonant tunneling through quantum dot. The Hamiltonian is exactly diagonalized by means of ..."
Offdiagonal generalized vector dominance in DIS and QCD. ∗ ∗∗
, 1999
"... We review the generalized vector dominance (GVD) approach to DIS at small values of the scaling variable, x. In particular, we concentrate on a recent formulation of GVD that explicitly incorporates the configuration of the γ ∗ → q¯q transition and a QCD–inspired ansatz for the (q¯q)p scattering am ..."

Comment on the AldayMaldacena solution in calculating scattering amplitude via AdS/CFT, arXiv: 0711.2828
"... Following the recent proposal of Alday and Maldacena to obtain the strong coupling scattering amplitude in N = 4 SYM theory via AdS/CFT, we point out that a unique solution can be obtained by imposing all the Virasoro constraints. This solution is identical to the AldayMaldacena solution for the fo ..."

By using their proposal [1], Alday and Maldacena computed the explicit form of the amplitude for the scattering of four gluons and found precise agreement with the BDS ansatz at the first order of strong coupling.
