Do α-acyloxy and α-alkoxycarbonyloxy radicals fragment to form acyl and alkoxycarbonyl radicals?

open access: yesBeilstein Journal of Organic Chemistry, 2006
The generation of α-acyloxy and α-alkoxycarbonyloxy radicals under reductive conditions in fragmentable probe experiments does not provide unequivocal evidence for the fragmentation of such radicals to give ketones and acyl or alkoxycarbonyl radicals ...

Financial Decisions Based on Zero-Sum Games: New Conceptual and Mathematical Outcomes

open access: yesInternational Journal of Financial Studies
All the n possible returns on a financial asset are the components of an element of a linear space over R. This paper shows how to transfer all these n possible returns on a one-dimensional straight line.

Micromagnetic study on Nd2Fe14B/α-Fe nanocomposite with inter-granular phase

open access: yesAIP Advances, 2023
The magnetic performance of hard-/soft-phase nanocomposites depends on their microstructure. Nanocomposites with an inter-granular phase, fabricated via a physical route, are fascinating as they can further enhance the magnetic properties of hard-/soft ...

Invariance of the Mathematical Expectation of a Random Quantity and Its Consequences

open access: yesRisks
Possibility and probability are the two aspects of uncertainty, where uncertainty represents the ignorance of a given individual. The notion of alternative (or event) belongs to the domain of possibility.

Synthesis of Phenolic Compounds by Trapping Arynes with a Hydroxy Surrogate

open access: yesMolecules, 2015
Trapping of arynes with various nucleophiles provides a range of heteroatom-functionalized arene derivatives, but the corresponding reaction with water does not provide phenol derivatives. Silver trifluroacetate (AgO2CCF3) can nicely solve this problem.

Human Umbilical Cord-Derived Mesenchymal Stem Cells Utilize Activin-A to Suppress Interferon-γ Production by Natural Killer Cells

open access: yesFrontiers in Immunology, 2014
Following allogeneic hematopoietic stem cell transplantation (HSCT), interferon (IFN)-γ levels in the recipient's body can strongly influence the clinical outcome. Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) are lucrative as biological tolerance inducers in HSCT settings.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.
