Response to Ward

Elastic response and Ward identities in stressed nematic elastomers.

Nematic elastomers exhibit a rich elastic response to external stresses. Of particular interest is the semisoft response of elastomers with an anisotropy direction (z) frozen in by a double cross-linking process. This response is characterized by a stress-strain curve for stresses along x perpendicular to z that rises initially, exhibits a nearly flat plateau between two critical values of stra...

[Involuntary admissions to an acute psychiatric ward].

BACKGROUND Involuntary admission to acute psychiatric wards in Norway has not been studied empirically after the introduction of a new Mental Health Act (MHA) 1 January 2001. According to the MHA, observation with coercion can be used to clarify illness. The objectives of this study were to describe scale and circumstances associated with involuntary admissions. METHOD All patients discharged...

To ward a Compatible Filesystem Interface

As network or remote filesystems have been implemented for UNIX,† several stylized interfaces between the filesystem implementation and the rest of the kernel have been developed. Notable among these are Sun Microsystems’ Virtual Filesystem interface (VFS) using vnodes, Digital Equipment’s Generic File System (GFS) architecture, and AT&T’s File System Switch (FSS). Each design attempts to isola...

Solution to the Ward Identities for Superamplitudes

Supersymmetry and R-symmetry Ward identities relate on-shell amplitudes in a supersymmetric field theory. We solve these Ward identities for NMHV amplitudes of the maximally supersymmetric N = 4 and N = 8 theories. The resulting superamplitude is written in a new, manifestly supersymmetric and R-invariant form: it is expressed as a sum of very simple SUSY and SU(N )R-invariant Grassmann polynom...
