Analysis of Fuzzy Vector Spaces as an Algebraic Framework for Flag Codes

Mathematics
Flag codes are a recent network coding strategy based on linear algebra. Fuzzy vector subspaces extend the notions of classical linear algebra. They can be seen as abstractions of flags to the point that several fuzzy vector subspaces can be identified ...

On coupling and “vacant set level set” percolation

Electronic Communications in Probability, 2019
In this note we discuss vacant set level set percolation on a transient weighted graph. It interpolates between the percolation of the vacant set of random interlacements and the level set percolation of the Gaussian free field. We employ coupling and derive a stochastic domination from which we deduce in a rather general set-up a certain monotonicity ...

Level sets and non Gaussian integrals of positively homogeneous functions [PDF]

, 2011
We investigate various properties of the sublevel set $\{x \,:\,g(x)\leq 1\}$ and the integration of $h$ on this sublevel set when $g$ and $h$are positively homogeneous functions.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

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 ...

Differentiating Thick Clouds From Thin Clouds by Using Intensity Inhomogeneity

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Clouds are usually present in optical satellite images, yet they occlude the ground truth, making it difficult to interpret satellite images. Moreover, distinguishing between areas with thick clouds and thin clouds is challenging when using the existing ...

Detailed Voxel-Based Implicit Modeling With Local Boolean Composition of Discrete Level Sets

IEEE Access, 2020
Compared with the functionally-based implicit models, the level set models are usually defined by discretely sampling the implicit function values over the volume grid to represent the shapes, which are suitable for scientific computing and engineering ...

Level sets of infinite length

Commentarii Mathematici Helvetici, 1978
The geometry of level sets plays an important role in the analysis of various function-theoretic problems. Often, however, the level sets are so complicated that one must either choose sets associated with special levels (see [3], [4]) or resort to the approximation of level sets by shorter curves (see[l, pp. 550-553]).

Clinical Course and Impact of Breaks in Therapy for Children With Relapsed/Refractory Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pediatric relapsed or refractory (R/R) solid tumors carry a dismal prognosis, and postrelapse patient experiences are not well described. We present postrelapse outcomes, including number of R/R events and subsequent therapy regimens.

Probabilistic shape‐based segmentation method using level sets

IET Computer Vision, 2014
In this study, a novel probabilistic, geometric and dynamic shape‐based level sets method is proposed. The shape prior is coupled with the intensity information to enhance the segmentation results.

Convergence of Polynomial Level Sets [PDF]

Transactions of the American Mathematical Society, 1998
Summary: We give a characterization of pointwise and uniform convergence of sequences of homogeneous polynomials on a Banach space by means of the convergence of their level sets. Results are obtained both in the real and the complex case, as well as some generalizations to the nonhomogeneous case and to holomorphic functions in the complex case ...
