Maps on density operators preserving quantum f-divergences [PDF]

, 2013
For an arbitrary strictly convex function f defined on the non-negative real line we determine the structure of all transformations on the set of density operators which preserve the quantum f ...

An update on multimodal management of craniopharyngioma in children

Frontiers in Oncology, 2023
Craniopharyngioma (CP) represent 1.2-4.6% of all intracranial tumors in children and carry a significant morbidity due to their lesional intimacy with structures involved in neurological, visual, and endocrinological functions.

Order preserving functions on ordered topological vector spaces [PDF]

Bulletin of the Australian Mathematical Society, 1999
In this paper we prove the existence of continuous order preserving functions on ordered topological vector spaces in an infinite-dimensional setting. In a certain class of topological vector spaces we prove the existence of topologies for which every continuous total preorder has a continuous order preserving representation and show that the Mackey ...

Bounds and algorithms for the K-Bessel function of imaginary order [PDF]

, 2013
Using the paths of steepest descent, we prove precise bounds with numerical implied constants for the modified Bessel function of imaginary order and its first two derivatives with respect to the order.

Clinical Experience with Organ-Preserving Surgery in Placenta Accreta

Креативная хирургия и онкология, 2022
Introduction. A higher number of repeated cesarean sections determine a higher risk of placental ingrowth into the scar area of the uterus. The absence of current clinical guidelines in this field necessitates the need for development of various methods ...

Nonlinear Model for Condition Monitoring and Fault Detection Based on Nonlocal Kernel Orthogonal Preserving Embedding

Shock and Vibration, 2018
The dimension reduction methods have been proved powerful and practical to extract latent features in the signal for process monitoring. A linear dimension reduction method called nonlocal orthogonal preserving embedding (NLOPE) and its nonlinear form ...

Order preserving transformations and applications [PDF]

, 2003
In this paper, we study the effects of a linear transformation on the partial order relations that are generated by a closed and convex cone in a finite-dimensional space.
