IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingRepresentation-based anomaly detection methods are one of the most popular methods in hyperspectral anomaly detection. Nevertheless, linear models of have difficulties in adequately describing complex data and generating a decision boundary for anomaly ...

Hypoelliptic heat kernel inequalities on the Heisenberg group
, 2005 We study the existence of “Lp-type” gradient estimates for the heat kernel of the natural hypoelliptic “Laplacian” on the real three-dimensional Heisenberg Lie group.

Journal of Functional Analysis, 2000 The principal result of the paper is a certain sufficient condition on the logarithmic derivative of the heat kernel under which a logarithmic Sobolev inequality on a loop space holds. Several applications are obtained: The logarithmic Sobolev inequality is proved on pinned path space on hyperbolic space with non-positive constant curvature where the ...

Business Strategy and the Environment, EarlyView.ABSTRACT Decarbonization of the economy is a central challenge in the fight against climate change. Although most governments show clear commitment to limiting global warming, the drivers of corporate decarbonization remain underexplored. Using a dataset of 1052 firms from OECD, this article analyses how intangible assets and environmental innovation ...

Heat kernel analysis on semi-infinite Lie groups
, 2009 This paper studies Brownian motion and heat kernel measure on a class of infinite dimensional Lie groups. We prove a Cameron–Martin type quasi-invariance theorem for the heat kernel measure and give estimates on the Lp norms of the Radon–Nikodym ...

Free Trade Zones and Corporate ESG: Evidence From a Quasi‐Natural Experiment in China
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how China's Pilot Free Trade Zones (FTZs) influence corporate ESG performance. Using a staggered difference‐in‐differences model on Chinese listed firms from 2009 to 2024, we combine coarsened exact matching (CEM) and geography‐based instrumental variables to ensure robust identification.

On the regularization of the ill-posed logarithmic kernel integral equation of the first kind
, 1995 The logarithmic kernel integral equation of the first kind is investigated as an improperly posed problem by considering its right-hand side as an observed quantity in a suitable space with a weaker norm. The improperly posed problem is decomposed into a

When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance
Business Strategy and the Environment, EarlyView.ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...
