Consistent two--dimensional chiral gravity [PDF]
, 1996 We study chiral induced gravity in the light-cone gauge and show that the theory is consistent for a particular choice of chiralities. The corresponding Kac--Moody central charge has no forbidden region of complex values.

Quantum caustics and the hierarchy of light cones in quenched spin chains
Physical Review Research, 2019 We show that the light conelike structures that form in spin chains after a quench are quantum caustics. Their natural description is in terms of catastrophe theory and this implies (1) a hierarchy of light cone structures corresponding to the different ...

2004 REVIEW OF LIGHT CONE FIELD THEORY [PDF]
International Journal of Modern Physics E, 2004 We review the basic concepts of the Poincare group in light cone quantum mechanics and light cone field theory. We discuss recent progress in light cone representations of the Bethe–Salpeter equation, with application to the pion form factor, and the quark Schwinger–Dyson equation.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity
FEBS Open Bio, EarlyView.Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

On the Twisted $N=2$ Superconformal Structure in $2d$ Gravity Coupled to Matter
, 1993 It is shown that the two dimensional gravity, described either in the conformal gauge (the Liouville theory) or in the light cone gauge, when coupled to matter possesses an infinite number of twisted $N=2$ superconformal symmetries.

Existence of positive solutions to some impulsive second-order integrodifferential equations
Electronic Journal of Differential Equations, 2010 In this article, we consider an initial-value problem for second-order nonlinear integrodifferential equations with impulses in a Banach space. By using the monotone iterative technique in a cone together with Arzela-Ascoli theorem and the dominated ...

Energy momentum tensor on and off the light cone: exposition with scalar Yukawa theory
Journal of High Energy PhysicsWe compute the gravitational form factors A i , D i and c ¯ i $$ {\overline{c}}_i $$ of the scalar Yukawa theory using both the light-cone and covariant perturbation theory at the one-loop level.

European Physical Journal C: Particles and Fields, 2021 We study the effects of adding the Coulomb interactions to the harmonic oscillator (HO) approximation of the heavy parton propagating through the quark–gluon plasma (the extension to QCD of the Molliere theory).

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.

Quantum Analysis of Jackiw and Teitelboim's Model for 1+1 D Gravity and Topological Gauge Theory
, 1992 We study the BRST quantization of the 1+1 dimensional gravity model proposed by Jackiw and Teitelboim and also the topological gauge model which is equivalent to the gravity model at least classically.
