Two-term Szegő theorem for generalised anti-Wick operators [PDF]
, 2015 This thesis concerns operators whose Weyl pseudodifferential operator symbol is the convolution of a function that is smooth and of fixed scale with a function that is discontinuous and dilated by a large asymptotic parameter.

Asian Journal of Control, EarlyView.ABSTRACT The synchronization accuracy between the wafer stage and reticle stage in lithography is critical to overlay and critical dimension uniformity. Existing iterative learning control (ILC) methods indirectly optimize synchronization via time‐domain errors, failing to balance low‐frequency tracking accuracy and high‐frequency noise suppression ...

Bootstrap Unit Root Tests [PDF]
We consider the bootstrap unit root tests based on autoregressive integrated models, with or without deterministic time trends. A general methodology is developed to approximate asymptotic distributions for the models driven by integrated time series ...

Matched Asymptotic Expansions for Valuing Spread Options [PDF]
, 2008 Spread Options are crucial in the energy, currency and fixed income, and com- modity markets. The problem with spread options is that there are no closed- form formulae to price or hedge them.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

The asymptotic Hopf algebra of Feynman integrals
Journal of High Energy PhysicsThe method of regions is an approach for developing asymptotic expansions of Feynman Integrals. We focus on expansions in Euclidean signature, where the method of regions can also be formulated as an expansion by subgraph.

"On Approximation of the Solutions to Partial Differential Equations in Finance" [PDF]
This paper proposes a general approximation method for the solutions to second-order parabolic partial differential equations (PDEs) widely used in finance through an extension of Léandre's approach(Léandre (2006,2008)) and the Bismut identiy(e.g ...

Business Strategy and the Environment, EarlyView.ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...

Business Strategy and the Environment, EarlyView.ABSTRACT Focusing on firm‐size heterogeneity, this study examines how institutional reform reshapes the effects of environmental, social, and governance (ESG) disclosure on firm value. Using 2019–2023 panel data on 1427 Japanese listed firms (before and after the 2022 Tokyo Stock Exchange reorganization and Corporate Governance Code revision), this ...

Solutions approaching polynomials at infinity to nonlinear ordinary differential equations
Electronic Journal of Differential Equations, 2005 This paper concerns the solutions approaching polynomials at $infty $ to $n$-th order ($n$ greater than 1) nonlinear ordinary differential equations, in which the nonlinear term depends on time $t$ and on $x,x',dots ,x^{(N)}$, where $x$ is the unknown ...
