Commutator criteria for strong mixing [PDF]
, 2014 We present new criteria, based on commutator methods, for the strong mixing property of discrete flows $\{U^N\}_{N\in\mathbb Z}$ and continuous flows $\{{\rm e}^{-itH}\}_{t\in\mathbb R}$ induced by unitary operators $U$ and self-adjoint operators $H$ in ...

Nature, 1947 THE importance of the study of natural hybridization is obvious in view of the large part it plays in the process of evolution. There have been considerable differences of opinion, first as to the possibility of recognizing natural hybrids and, secondly, as to the status of the parents once the possibility of hybridization has been established.

Journal of Algebra, 1995 Let \(f : (X,x) \to (Y,y)\) be a morphism of local schemes and \((Z,x)\) the central fiber. The flatness of \(f\) is a subtle geometric notion and it is difficult to find some flatness criteria which do not require infinitesimal properties. A well-known result of \textit{H. Hironaka} [Ill.

, 2000 In the noncommutative geometry of Artin, Van den Bergh, and others, the twisted homogeneous coordinate ring is one of the basic constructions. Such a ring is defined by a $\sigma$-ample divisor, where $\sigma$ is an automorphism of a projective scheme X.

Toxics, 2023 Novel brominated flame retardants (NBFRs) have been widely used as alternatives to legacy BFRs. However, information on the contamination status and human exposure risks of electronic waste (e-waste)-derived NBFRs in the e-waste workplace is limited.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...
