Many different methods have been proposed for determining islanding and most of them have drawbacks. The main issue is the difficulty of detecting islanding when the current and voltage values are of the same phase or the frequency remains within the ...

Extensions of generalized homology theories [PDF]
Let E denote a CW-spectrum and \(E_*(-)\) the corresponding homology theory on the category of based finite CW-complexes. The following extension problems are discussed: Can \(E_*(-)\) be extended over the category of based compact metric spaces or over the strong shape category? Under what circumstances is such an extension uniquely determined?

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 ...

Resonance as a medio-passive, emancipatory and transformative power: a reply to my critics
This is a response to a critique of my theory in the Journal of Chinese Sociology. In this response, I take the relationship between resonance theory and the tradition of critical theory as the starting point, and discuss the contributions of the five ...

ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

We develop a theory of P-shape for the class of compact Hausdorff spaces and for certain CW-complexes P. The complexes P which are allowed are those which, for each given weight α , admit a P- invertible map of a compact Hausdorff space of weight ≤ α and of extension dimension ≤ P onto the Tychonoff cube I α .

Clifford theory for cocentral extensions [PDF]
The classical Clifford correspondence for normal subgroups is considered in the more general setting of semisimple Hopf algebras. We prove that this correspondence still holds if the extension determined by the normal Hopf subalgebra is cocentral.
