MicroRNAs in Uteroplacental Vascular Dysfunction

open access: yesCells, 2019
Pregnancy complications of preeclampsia and intrauterine growth restriction (IUGR) are major causes of maternal and perinatal/neonatal morbidity and mortality.

Assessing Eco‐Efficiency and the Cost of Carbon Abatement in Wastewater Treatment: Evidence From Spain

open access: yesSustainable Development, EarlyView.
ABSTRACT Wastewater treatment plants (WWTPs) play a critical role in protecting public health and the environment but are also contributors to carbon emissions. Improving the eco‐efficiency of WWTPs is essential for advancing sustainability in the sector.

What Program for Love in the 21st Century? Thinking With and Beyond Luhmann

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT From a sociological perspective, the paper examines how normative frameworks for intimate relationships have changed since the publication of Luhmann's Love as Passion (1982). Building on Luhmann's notion of a program for love, we discuss his claim that late 20th century love semantics were organized around a program of understanding. We argue

Antenatal Hypoxia and Programming of Glucocorticoid Receptor Expression in the Adult Rat Heart

open access: yesFrontiers in Physiology, 2019
Glucocorticoid receptor (GR) signaling is critical for development and function of the heart. Our previous study demonstrated that gestational hypoxia induced epigenetic repression of the GR gene in the developing heart.

Nets of Subfactors

open access: yes, 1994
A subtheory of a quantum field theory specifies von~Neumann subalgebras $\aa(\oo)$ (the `observables' in the space-time region $\oo$) of the von~Neumann algebras $\bb(\oo)$ (the `fields' localized in $\oo$).

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

The Bisognano-Wichmann Theorem for Charged States and the Conformal Boundary of a Black Hole

open access: yes, 2000
Recent applications of Operator Algebras to Quantum Field Theory on a Curved Spacetime show that the incremental entropy associated with a quantum black hole, due the addition of a short range charge, is quantized proportionally to the logarithm of an ...

Demographic buffering in natural populations: A multi‐level perspective

open access: yesJournal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

An Isolated Phlebolith on the Lip: An Unusual Case and Review of the Literature

open access: yesCase Reports in Pathology, 2015
Background. Calcified thrombi are a common finding, especially in the pelvic veins. There are generally multiple thrombi, and they are generally associated with vascular malformations. Design.

Structure and Classification of Superconformal Nets

open access: yes, 2007
We study the general structure of Fermi conformal nets of von Neumann algebras on the circle, consider a class of topological representations, the general representations, that we characterize as Neveu-Schwarz or Ramond representations, in particular a ...
