Flutter Control of a Quasi-three-dimensional Wing in Simplified Unsteady Flow using Forced Jet [PDF]
مکانیک هوافضاOne of the special topics in the aeroelastic field is the flutter of the airplane wing at an index speed called the flutter speed, which, if this phenomenon is not controlled, there will be a possibility of destroying the structure (airplane wing ...

The quantum strip: Liouville theory for open strings [PDF]
Communications in Mathematical Physics, 1992 In the original operator approach to Liouville theory on the strip initiated by the second author and \textit{A. Neveu} [Nucl. Phys. B 238, 125-141 (1984)] only the simplest inverse power of the metric tensor operator could be derived. Using the quantum group structure of two- dimensional gravity recently found by the second author [Commun. Math. Phys.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Perturbation Theory for Lyapunov Exponents of an Anderson Model on a Strip [PDF]
Geometric And Functional Analysis, 2004 It is proven that the inverse localization length of an Anderson model on a strip of width $L$ is bounded above by $L/λ^2$ for small values of the coupling constant $λ$ of the disordered potential. For this purpose, a formalism is developed in order to calculate the bottom Lyapunov exponent associated with random products of large symplectic matrices ...

FEBS Open Bio, EarlyView.IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.
