In previous papers we built (multiple) D-branes in flat space-time as classical solutions of the string field theory based on the tachyon vacuum. In this paper we construct classical solutions describing all D-branes in any fixed space-time background defined by a two dimensional CFT of central charge 26. A key role is played by the geometrical definition of the sliver state in general boundary...

The effect of drafts at different stages of spinning process on fibre length distribution of slivers has been studied by using Taguchi Method and ANOVA technique. The L8 mixed orthogonal array was used to work out eight different slivers. Two different lap hanks, four different card drafts and two different draft/doublings at breaker and finisher were selected for the study. The fibrograph leng...

We give a comment on the possible rôle of the sliver state in the generic boundary conformal field theory. We argue that for each Cardy state, there exists at least one projector in the string field theory. ∗E-mail address: [email protected] One of the long standing problem in the string theory is the description of the geometry. Generically we do not need the space-time at all to def...

The Ag nanoparticles with no need for reduction supported on MgAl-layered double hydroxide (LDH) were prepared. (NPs) achieved in the LDH support by situ reduction, meanwhile, metal nickel generated reaction mechanisms of hydrogenation citral. Sliver generates highly mobile atomic hydrogen, which reduces abstracting H from surface support, and formed after reaction. action sliver nickelare cond...

The paper is focused on modelling and control of an important textile engineering process: the textile sliver drafting process. This process plays a crucial role in textile production chain because low irregularity of drafted sliver is essential for production of high quality yarn. It is shown that this process can be modelled as a nonlinear time delay system with distributed delays. This model...

Increasing transistor densities, smaller feature sizes, and the aggressive use of RET techniques with each successive process generation have collectively presented new challenges for current fracture tools, which are at the heart of layout data preparation. One main challenge is to reduce the number of small dimension trapezoids (slivers) to improve mask yield since the sliver count reflects t...

We evaluate the tachyon potential in the Schnabl gauge through off-shell computations in the sliver frame. As an application of the results of our computations, we provide a strong evidence that Schnabl’s analytic solution for tachyon condensation in open string field theory represents a saddle point configuration of the full tachyon potential. Additionally we verify that Schnabl’s analytic sol...

We consider a new class of solutions (dressed slivers) in Vacuum String Field Theory, which represent D25–branes. For each dressed sliver we introduce a deformation parameter and define a family of states which are characterized by new abelian ∗– subalgebras. We show that this deformation parameter can be used as a regulator: it allows us to define for each such solution a finite norm and energ...

We analytically prove that the matter solution of vacuum string field theory constructed by Kostelecky and Potting is the matter sliver state. We also give an analytical proof that the ghost solution by Hata and Kawano is the sliver state in the twisted ghost CFT. It is also proved that the candidate state for the tachyon proposed by Hata and Kawano can be identified with the state constructed ...
