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. J. Math.

Entanglement criteria for Dicke states [PDF]
, 2013 Dicke states are a family of multi-qubit quantum states with interesting entanglement properties and have been observed in many experiments. We construct entanglement witnesses for detecting genuine multiparticle entanglement in the vicinity of these ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Restoration of aquatic vegetation can mitigate the risk of eutrophication in large shallow lakes
Scientific ReportsThe role of aquatic vegetation restoration in mitigating lake eutrophication is well-recognized, yet the underlying nutrient dynamics-vegetation response relationship remains poorly quantified, hindering a mechanistic understanding of grass-algae regime ...
