Emittance preservation in linear accelerators [PDF]
AIP Conference Proceedings, 2001 In linear colliders preservation of the phase space density of charged particles during acceleration to high energies is essential. In practice, the electromagnetic fields which govern the beam transport may not be sufficiently well understood. This may arise, for example, from magnet and structure alignment and/or manufacturing errors, time-varying ...

Latin-majorization and its linear preservers [PDF]
Sahand Communications in Mathematical Analysis, 2017 In this paper we study the concept of Latin-majorizati-\on. Geometrically this concept is different from other kinds of majorization in some aspects.

Preservers for the p-Norm of Linear Combinations of Positive Operators
Abstract and Applied Analysis, 2014 We describe the structure of those transformations on certain sets of positive operators which preserve the p-norm of linear combinations with given nonzero real coefficients. These sets are the collection of all positive pth Schatten-class operators and

On Partially Trace Distance Preserving Maps and Reversible Quantum Channels
Journal of Applied Mathematics, 2013 We give a characterization of trace-preserving and positive linear maps preserving trace distance partially, that is, preservers of trace distance of quantum states or pure states rather than all matrices.

Linear preservers of row-dense matrices [PDF]
Czechoslovak Mathematical Journal, 2016 The authors deal with linear preserves problems of row-dense matrices. A rectangular matrix \(A\) is row-dense if there are no zeros between two nonzero entries in its rows. Furthermore \(A\) is a column-dense matrix if \(A^T\) is row-dense. The structure of linear functions \(T:M_{m,n}\mapsto M_{m,n}\) that preserve or strongly preserve row-dense ...

Unbounded Disjointness Preserving Linear Functionals [PDF]
Monatshefte f�r Mathematik, 2004 Let \(X\) and \(Y\) be locally compact Hausdorff spaces and let \(C_0(X)\) be the Banach space of continuous (real or complex-valued) functions on \(X\) vanishing at infinity. A linear operator \(T:C_0(X) \to C_0(Y)\) is called disjointness-preserving if \(fg=0\) implies \(T(f) T(g) =0\) for all \(f,g\in C_0(X).\) \textit{K. ~Jarosz} [Can. Math.

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 ...
