Exactness of reduced amalgamated free product C*-algebras [PDF]
arXiv, 1999 Some completely positive maps on reduced amalgamated free products of C*-algebras are constructed; these allow a proof that the class of exact unital C*-algebras is closed under taking reduced amalgamated free products. Consequently, the class of exact discrete groups is closed under taking amalgamated free products.

Positive Strong Amalgamation [PDF]
arXiv, 2019 We present the notions of positively complete theory and general forms of amalgamation in the framework of positive logic. We explore the fundamental properties of positively complete theories and study the behaviour of companion theories by a change of constants in the language.

Notions of amalgamation for AECs and categoricity [PDF]
arXiv, 2021 Motivated by the free products of groups, the direct sums of modules, and Shelah's $(\lambda,2)$-goodness, we study strong amalgamation properties in Abstract Elementary Classes. Such a notion of amalgamation consists of a selection of certain amalgams for every triple $M_0\leq M_1, M_2$, and we show that if $K$ designates a unique strong amalgam to ...

Energy Science &Engineering, EarlyView.The graphical abstract depicts biodiesel production from algae and plastic waste via oil extraction, transesterification, and pyrolysis. These fuels were tested for diesel engine performance, improve combustion, and reduce emissions. ABSTRACT This study investigates the performance and emission characteristics of a diesel engine running on a blend of ...

Geophysical Monograph Series, Page 435-447., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

arXiv, 2012 We study the amalgamation property in positive logic. We give some connections between the amalgamation property and Robinson theories, model-complete theories and the Hausdorff property.

Exploration, EarlyView.Schematic illustration of structural and functional biomimicry. The upper part shows BP with various structures such as monolayered, surface‐microstructural, bilayered and multilayered. The bottom part exhibits BP with different functions including immune regulation, drugs/cells/factors/ions loading, as well as bioelectrical stimulation and ...

iMetaOmics, EarlyView.The PANDA pipeline for colorectal cancer (CRC) analysis integrates metabolomic data from LC‐MS with machine learning techniques to classify CRC stages and predict biomarkers. Initially, the raw metabolomic data is processed using partial least squares discriminant analysis (PLS‐DA) to reduce dimensionality and highlight key features.

LuminescenceABSTRACTMirabegron, a drug for treatment of overactive bladder, has low water solubility and bioavailability. Researchers used quality by design to develop and characterize second‐generation lipid nanocarriers for mirabegron, aiming to provide spatially and temporally sustained drug release. Numerous analytical methodologies for assessing mirabegron in

Sodium Retention in Large Herbivores: Physiological Insights and Zoogeochemical Consequences
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.Sodium travels twice as fast through the bodies of large herbivores in urine than feces. The specific pathway of element assimilation, retention and release exerts an important constraint on the contributions of wildlife and domestic livestock to nutrient recycling and redistribution.
