Hamiltonian approach to GR – Part 2: covariant theory of quantum gravity
European Physical Journal C: Particles and Fields, 2017 A non-perturbative quantum field theory of General Relativity is presented which leads to a new realization of the theory of covariant quantum gravity (CQG-theory). The treatment is founded on the recently identified Hamiltonian structure associated with

The robust Orlicz risk with an application to the green photovoltaic power generation
Asian Journal of Control, Volume 27, Issue 4, Page 1655-1667, July 2025.Abstract We propose a novel recursive utility for controlling stochastic processes under risk and uncertainty. Our formulation uses a robustified Orlicz risk that can evaluate risk and uncertainty simultaneously. We focus on the control problem of a photovoltaic power generation system that supplies excess electricity for the secondary purpose of ...

Mass transport in low‐temperature ceramic sintering and printing assisted by pressure and water
Journal of the American Ceramic Society, Volume 108, Issue 7, July 2025.Ceramic processing assisted by pressure and water offers a sustainable, low‐temperature approach to ceramic sintering and three‐dimensional printing. During the processing, external pressure is applied to ceramic particles in the presence of water, which accelerates mass transport across interparticle contact points and pores at reduced temperatures ...

Life‐cycle planning model with stochastic volatility and recursive preferences
International Review of Finance, Volume 25, Issue 2, June 2025.Abstract This study examines the optimal investment, consumption, and life insurance choices faced by a wage earner with recursive preferences within a finite time horizon. We posit that the financial market comprises a risk‐free asset and a risky asset that follows a general stochastic volatility model.

A Killing tensor for higher dimensional Kerr-AdS black holes with NUT charge
, 2006 In this paper, we study the recently discovered family of higher dimensional Kerr-AdS black holes with an extra NUT-like parameter. We show that the inverse metric is additively separable after multiplication by a simple function.

Backstepping boundary control design for a cascaded viscous Hamilton–Jacobi PDE–ODE system
IET Control Theory & Applications, 2021 This paper develops state‐feedback and output‐feedback control design methodologies for boundary stabilization of a class of systems that involves cascade connection of a non‐linear viscous Hamilton–Jacobi partial differential equation (PDE) and a ...

On the Zoll deformations of the Kepler problem
Bulletin of the London Mathematical Society, Volume 57, Issue 6, Page 1749-1767, June 2025.Abstract A celebrated result of Bertrand states that the only central force potentials on the plane with the property that all bounded orbits are periodic are the Kepler potential and the potential of the harmonic oscillator. In this paper, we complement Bertrand's theorem showing the existence of an infinite‐dimensional space of central force ...
