Holographic description of M-branes via AdS2

open access: yesJournal of High Energy Physics, 2020
We study AdS2 × S 4 × S 2 × Σ2 solutions in type IIB string theory arising from D1-D3-NS5 brane intersections. These backgrounds enjoy sixteen supercharges and the corresponding internal geometry is non-compact due to the specific form of the warping w.r.

Target space entanglement in quantum mechanics of fermions at finite temperature

open access: yesJournal of High Energy Physics, 2022
We consider the target space entanglement in quantum mechanics of non-interacting fermions at finite temperature. Unlike pure states investigated in [1], the (Rényi) entanglement entropy for thermal states does not follow a simple bound because all ...

Effect of heparin and related glycosaminoglycan on PDGF‐induced lung fibroblast proliferation, chemotactic response and matrix metalloproteinases activity

open access: yesMediators of Inflammation, Volume 9, Issue 2, Page 85-91, 2000., 2000
Fibroblast migration, proliferation, extacellular matrix protein synthesis and degradation are the key events in various biological and pathological processes in pulmonary fibrosis. In addition, biopsy specimens from the lungs of patients with plumomary fibrosis show increased numbers of mast cells which have metachromatic granules containing heparin ...

Target space entanglement entropy

open access: yesJournal of High Energy Physics, 2023
We define a notion of target space entanglement entropy. Rather than partitioning the base space on which the theory is defined, we consider partitions of the target space.

Progress in the Molecular Biology of Ewing Tumors

open access: yesSarcoma, Volume 2, Issue 1, Page 3-17, 1998., 1998
Purpose/results/discussion. Rearrangement of the EWS gene with an ETS oncogene by chromosomal translocation is a hallmark of the Ewing family of tumors (EFT). Detectability, incidence, tumor specificity and variability of this aberration have been matters of intense investigation in recent years.

Lorentz symmetry and IR structure of the BFSS matrix model

open access: yesJournal of High Energy Physics, 2023
The BFSS matrix model relates flat space M-theory to a large N limit of matrix quantum mechanics describing N non-relativistic D0-branes. M-theory, being a theory of gravity in flat space, has a rich infrared structure that includes various soft theorems

Susceptibility of lung epithelium to neutrophil elastase: protection by native inhibitors

open access: yesMediators of Inflammation, Volume 6, Issue 5-6, Page 345-354, 1997., 1997
The development of emphysema is thought to be due to an imbalance of proteases (especially neutrophil elastase [NE]) and antiproteases with loosening of the respiratory epithelium as an early event. We investigated the effect of NE on respiratory epithelial cell adherence in vitro , in the presence of varying concentrations and combinations of native ...

Spontaneous symmetry breaking in tensor theories

open access: yesJournal of High Energy Physics, 2019
In this work we study spontaneous symmetry breaking patterns in tensor models. We focus on the patterns which lead to effective matrix theories transforming in the adjoint of U(N).

Convergence analysis of the iterative methods for quasi complementarity problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 11, Issue 2, Page 319-334, 1988., 1988
In this paper, we consider the iterative methods for the quasi complementarity problems of the form where m is a point‐to‐point mapping and T is a continuous mapping from Rn into itself. The algorithms considered in this paper are general and unified ones, which include many existing algorithms as special cases for solving the complementarity problems.
