Level crossing along sphaleron barriers [PDF]
Physical Review D, 1994 In the electroweak sector of the standard model topologically inequivalent vacua are separated by finite energy barriers, whose height is given by the sphale\-ron. For large values of the Higgs mass there exist several sphaleron solutions and the barriers are no longer symmetric.

An AHP model for level crossing design [PDF]
International Journal of Safety and Security Engineering, 2018 Level crossings (LC) are places of rail and road intersections and therefore areas with increased risk of severe accidents. The main objective of this study is to apply the multi-criteria Analytical Hierarchy Process (AHP) method to evaluate the variants for the reconstruction of LCs in an urban environment through weighting of various criteria and sub-

Level-Crossing Optogalvanic Spectroscopy
Le Journal de Physique Colloques, 1983 Optogalvanic spectroscopy is applied to the detection of level -crossings at zero and finite magnetic fields. The method provides a sensitive, Doppler-free technique for determining hyperfine structures in both lower and upper levels of atomic transitions.

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 ...

Safe implementation of automatic microprocessor systems of level crossing on the example of the SPA-4 system [PDF]
Transport Problems, 2007 Fulfilling high requirements of safety and reliability is an importantquestion in devices of railway traffic control. Increased safety in computer systems is reached in the simplest way through redundancy of hardware and software, but also with other ...

Semigroup Structures and Commutative Ideals of BCK-Algebras Based on Crossing Cubic Set Structures
Axioms, 2022 First, semigroup structure is constructed by providing binary operations for the crossing cubic set structure. The concept of commutative crossing cubic ideal is introduced by applying crossing cubic set structure to commutative ideal in BCK-algebra, and
