String field theory of c ⩽ 1 noncritical strings [PDF]

Physics Letters B, 1994
We construct a string field Hamiltonian for a noncritical string theory with the continuum limit of the Ising model or its generalization as the matter theory on the worldsheet. It consists of only three string vertices as in the case for $c=0$. We also discuss a general consistency condition that should be satisfied by this kind of string field ...

Vibration‐Mediated Recovery of Irradiated Osteocytes and Their Regulatory Role in Breast Cancer Bone Metastasis

Advanced Healthcare Materials, EarlyView.
Radiotherapy damages bone and disrupts osteocyte function, yet mechanically mediated protection remains largely unexplored. This study demonstrates that low‐magnitude, high‐frequency (LMHF) vibration mitigates irradiated osteocyte apoptosis, restores their ability to regulate breast cancer extravasation, and acts synergistically with radiotherapy to ...

Closed string amplitudes around tachyon vacuum solution in Kaku theory

Journal of High Energy Physics
We incorporate closed string field into Kaku’s open string field theory which is defined using Kaku vertex, and we construct open-closed string field theory.

Topological defects in open string field theory

Journal of High Energy Physics, 2018
We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of Graham and Watts to include the action of defects on boundary condition ...

Marginal deformations in string field theory [PDF]

, 2007
We describe a method for obtaining analytic solutions corresponding to exact marginal deformations in open bosonic string field theory. For the photon marginal deformation we have an explicit analytic solution to all orders.

Field Theory Expansions of String Theory Amplitudes

Physical Review Letters
Motivated by quantum field theory (QFT) considerations, we present new representations of the Euler-Beta function and tree-level string theory amplitudes using a new two-channel, local, crossing symmetric dispersion relation. Unlike standard series representations, the new ones are analytic everywhere except at the poles, sum over poles in all channels,

Associativity anomaly in string field theory [PDF]

Physical Review D, 2002
We give a detailed study of the associativity anomaly in open string field theory from the viewpoint of the split string and Moyal formalisms. The origin of the anomaly is reduced to the properties of the special infinite size matrices which relate the conventional open string to the split string variables, and is intimately related to midpoint issues.

Growth Hormone‐Loaded 3D Printed Silk Fibroin‐Cellulose Dressings for Ischemic Wounds

Advanced Healthcare Materials, EarlyView.
3D‐printed wound dressings combining carboxymethyl cellulose, silk fibroin, and growth hormone accelerate healing in diabetic ulcers. These bioactive, customizable dressings enhance angiogenesis, cellular proliferation, and immune modulation. Proteomic analysis reveals activation of regenerative pathways and reduced fibrosis, highlighting their ...

Normalization of ZZ instanton amplitudes in minimal string theory

Journal of High Energy Physics, 2022
We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane.

Closed String Amplitudes from Gauge Fixed String Field Theory [PDF]

, 2002
Closed string diagrams are derived from cubic open string field theory using a gauge fixed kinetic operator. The basic idea is to use a string propagator that does not generate a boundary to the world sheet.
