Solutions of the Vacuum String Field Theory (VSFT) equation of motion involving matter part are given by projectors, and they represent nonperturbative solutions (e.g. the sliver) interpreted as D25-branes (or lower dimensional branes), but they are not mathematically well defined as they have zero norm. In this work we will use a regularization procedure based on the cutoff version of Moyal St...

Integrate-and-express models of synaptic plasticity propose that synapses integrate plasticity induction signals before expressing synaptic plasticity. By discerning trends in their induction signals, synapses can control destabilizing fluctuations in synaptic strength. In a feedforward perceptron framework with binary-strength synapses for associative memory storage, we have previously shown t...

Far from being a simple reflection of reality, archives are constructed windows into personal and collective processes. They at once express and are instruments of prevailing relations of power. Verne Harris makes these arguments through an account of archives and archivists in the context of South Africa’s transition from apartheid to democracy. The account is deliberately shaped around three ...

Identification by Bhattacharya et al. (1994) of seafloor spreading type magnetic anomalies in the basin lying between Laxmi Ridge in the Arabian Sea and the Indian continent necessitates a change in plate tectonic reconstruction. Naini and Talwani (1982) named this basin the Eastern Basin and we will continue to use this term in this paper. Others, in the literature, have called this the Laxmi ...

A k ey step in the nite element method is to generate well-shaped meshes in 3D. A mesh is well-shaped if every tetrahedron element has a small aspect ratio. It is an old outstanding problem to generate well-shaped Delaunay meshes in three or more dimensions. Existing algorithms do not completely solve this problem, primarily because they can not eliminate all slivers. A sliver is a tetrahedron ...

In this letter, we attempt to correct a potentially serious misperception arising from the paper "Rats maintain an overhead binocular field at the expense of constant fusion". While the authors repeatedly emphasize that the animal's binocular field is overhead, the authors' own data show that the truth is quite different, even orthogonal: the binocular field is in fact centered dead-ahead in fr...
