Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Warped AdS 6 × S 2 in Type IIB supergravity III. Global solutions with seven-branes

Journal of High Energy Physics, 2017
We extend our previous construction of global solutions to Type IIB super-gravity that are invariant under the superalgebra F(4) and are realized on a spacetime of the form AdS 6 × S 2 warped over a Riemann surface Σ by allowing the supergravity fields ...

Approximations from Anywhere and General Rough Sets

, 2017
Not all approximations arise from information systems. The problem of fitting approximations, subjected to some rules (and related data), to information systems in a rough scheme of things is known as the \emph{inverse problem}.

Measuring Institutional Work in Sustainability Reporting: Scale Development and Validation in the Oil and Gas Sector

Sustainable Development, EarlyView.
ABSTRACT Sustainability reporting has gained significant importance in assessing and enhancing organisational sustainability performance. However, there has been limited focus on how sustainability reporting managers (SRMs) perceive and engage in the institutional work that underpins reporting practices.

Semi-classical Virasoro blocks: proof of exponentiation

Journal of High Energy Physics, 2020
Virasoro conformal blocks are expected to exponentiate in the limit of large central charge c and large operator dimensions hi, with the ratios hi/c held fixed.

Janus and RG interfaces in three-dimensional gauged supergravity. Part II. General α

Journal of High Energy Physics, 2022
In this paper, we continue the study of Janus and RG-flow interfaces in three dimensional supergravity continuing the work presented in [1]. We consider N $$ \mathcal{N} $$ = 8 gauged supergravity theories which have a N $$ \mathcal{N} $$ = (4, 4) AdS 3 ...

Many Ceramides [PDF]

Journal of Biological Chemistry, 2011
Intensive research over the past 2 decades has implicated ceramide in the regulation of several cell responses. However, emerging evidence points to dramatic complexities in ceramide metabolism and structure that defy the prevailing unifying hypothesis on ceramide function that is based on the understanding of ceramide as a single entity.

Fair Markets and Resilient Supply Chains: Designing Sustainable Intermediation for Rural Communities

Sustainable Development, EarlyView.
ABSTRACT Agriculture in Ecuador's communes faces significant economic, social, and environmental challenges, intensified by supply chains dominated by traditional intermediaries. The lack of context‐specific sustainability studies further increases the vulnerability of smallholders.

Manifesting enhanced cancellations in supergravity: integrands versus integrals

Journal of High Energy Physics, 2017
Examples of ‘enhanced ultraviolet cancellations’ with no known standard-symmetry explanation have been found in a variety of supergravity theories. By examining one- and two-loop examples in four- and five-dimensional half-maximal supergravity, we argue ...

Properties of infinite product amplitudes: Veneziano, Virasoro, and Coon

Journal of High Energy Physics, 2022
We detail the properties of the Veneziano, Virasoro, and Coon amplitudes. These tree-level four-point scattering amplitudes may be written as infinite products with an infinite sequence of simple poles.
