M often employ market response models as decision aids and historical information of competitors’ market outcomes to aid their competitive decisions in oligopolistic settings. However, little is known about how access to a decision aid or the availability of competitors’ market outcomes impact a firm’s competitive decisions (e.g., prices) or market outcomes resulting from those decisions (e.g.,...

In this paper we introduce a stability radius for a wide class of linear innnite-dimensional time-varying systems under structured time{varying perturbations. A framework is presented which allows the same degree of unboundedness in the perturbations as in the generator of the nominal model.

We clarify the explici structure of the Hurwitz quaternion order, which is of fundamental importance in Riemann surface theory.

The paper is an attempt to generalize a methodology [1; 93] and [2, 3; 95], which is similar to the bounded-input bounded-output (BIBO) method currently widely used [4-9] for the system stability studies. The presented in [1, 2] methodology allows decomposition of input space into bounded subspaces and defining for each subspace its bounding surface. It also defines a corresponding predefined c...

This note introduces a stability radius for discrete time linear time-varying systems on Banach spaces under structured time-varying perturbations of multi{output feedback type. We derive counterparts to some results established for time-varying and/or innnite dimensional diierentiable systems in 3], 6].

We describe the synthesis of an abasic RNA phosphoramidite carrying a photocleavable 1-(2-nitrophenyl)ethyl (NPE) group at the anomeric center and a triisopropylsilyloxymethyl (TOM) group as 2'-O-protecting group together with the analogous DNA and the 2'-OMe RNA abasic building blocks. These units were incorporated into RNA-, 2'-OMe-RNA- and DNA for the purpose of studying their chemical stabi...

Various exact tests for showing a di&erence between two treatments or the non-inferiority (therapeutic equivalence) based on the di&erence of two binomial proportions are compared. It is found that a frequently used test has to be applied with great caution due to its numerical instability. Furthermore, a test based on the score statistic can be recommended as a good compromise between a simple...
