Warm Inflation and Scalar Perturbations of the Metric [PDF]

General Relativity and Gravitation, 2001
A second-order expansion for the quantum fluctuations of the matter field was considered in the framework of the warm inflation scenario. The friction and Hubble parameters were expended by means of a semiclassical approach. The fluctuations of the Hubble parameter generates fluctuations of the metric.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Potential Analysis of On‐Site Oxygen and Ozone Production for Wastewater Treatment Plants

Chemie Ingenieur Technik, EarlyView.
The potential of a power‐to‐gas process focusing on the oxygen stream to cover an upcoming demand of ozone at German wastewater treatment plants is analyzed. Economic and ecological parameters are compared to the conventional production of hydrogen and oxygen. Powered by on‐site produced wind energy, the process is deemed beneficial.

Primordial non-Gaussianity in noncanonical warm inflation with nonminimal derivative coupling

European Physical Journal C: Particles and Fields
In this paper, the scenario of noncanonical warm inflation with nonminimal derivative coupling is introduced, and its primordial non-Gaussianity of perturbations on uniform energy density hypersurfaces is systematically analyzed.

Assessing Climate Change Disclosure and Its Governance Drivers: Insights From the European Utilities Sector

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study aims to enhance academic understanding of the factors influencing the disclosure practices of climate change among European utility companies, specifically in the context of their sustainability reporting. The primary objective is to explore, through a multi‐theoretical framework, the governance drivers that significantly affect the

Tracking Climate and Environmental Attention: A News‐Based Composite Index

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

CEO Overconfidence and Corporate Social Responsibility: A Micro‐CSR Perspective

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Although research on micro‐level CSR has increasingly emphasized individual‐level antecedents, the role of CEO overconfidence has not been systematically integrated into the literature. To address this gap, a systematic literature review was undertaken of 62 studies on CEO overconfidence and CSR, revealing a mixed picture of positive, negative,

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Safe and Sound: Is Safeness a Specific Affective Dimension Related to Eating Disorder Behaviors?

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Safeness is a warm, soothing emotional state that is often experienced in the presence of close others. Safeness is thought to be distinct from other positive emotions or the absence of negative emotions and is shown to predict mental health variables over and above other emotions.
