Geometric approach to asymptotic expansion of Feynman integrals

open access: yesEuropean Physical Journal C: Particles and Fields, 2011
We present an algorithm that reveals relevant contributions in non-threshold-type asymptotic expansion of Feynman integrals about a small parameter. It is shown that the problem reduces to finding a convex hull of a set of points in a multidimensional ...

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Asymptotic Power Series of Field Correlators

open access: yesActa Polytechnica, 2010
We address the problem of ambiguity of a function determined by an asymptotic perturbation expansion. Using a modified form of theWatson lemma recently proved elsewhere, we discuss a large class of functions determined by the same asymptotic power ...

N‐of‐1 trials in clinical research: Methodological foundations, statistical approaches and implementation challenges

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
N‐of‐1 trials offer a unique and rigorous methodology for evaluating individualized treatment responses, particularly within the context of personalized medicine. This article provides a comprehensive explanation of the conceptual and methodological underpinnings of N‐of‐1 trials, with particular emphasis on statistical techniques and considerations ...

Does ESG Investing Pay off? Comparing the Performance of ESG and Traditional ETFs Across European and US Markets

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Investors have long recognized the importance of firms in promoting sustainability, leading to the rise of socially responsible investment (SRI). Specifically, there is a growing preference for exchange‐traded funds (ETFs) that prioritize environmental, social, and governance (ESG) principles.

Boards and ESG Performance: The Contingent Influence of Climate Vulnerability on Global Banks

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the contingent effect of climate vulnerability on the relationship between board characteristics and environmental, social, and governance (ESG) performance of global banks. We use a dataset of 438 banks across 54 countries (2010–2022) and fixed effects estimation, two‐stage least squares, and generalized method of moments ...

Asymptotic Expansion of the Solutions to Time-Space Fractional Kuramoto-Sivashinsky Equations

open access: yesAdvances in Mathematical Physics, 2016
This paper is devoted to finding the asymptotic expansion of solutions to fractional partial differential equations with initial conditions. A new method, the residual power series method, is proposed for time-space fractional partial differential ...

The ESG Emissions Paradox: Capability‐Contingent Effects of Research and Development and Cost Leadership in Asia

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the impact of greenhouse gas (GHG) emissions, research and development (R&D) spending, and cost leadership strategies (CLSs) on the environmental, social, and governance (ESG) performance of Asian firms from 2015 to 2023.
