Additive friction stir deposition vs. friction surfacing: Comparison of friction stir-based approaches for groove repair of high strength aluminum alloys

Materials & Design
Friction stir-based solid-state layer deposition techniques show considerable potential as additive manufacturing approach but also for repair applications.

Immanants and Finite Point Processes

Journal of Combinatorial Theory, Series A, 2000
Given a Hermitian, nonnegative definite kernel \(K\) and a character \(\chi\) of the symmetric group on \(n\) letters, the function \(K^\chi\) is symmetric and nonnegative, and, under suitable conditions, is also non-trivial and integrable with respect to the product measure \(\mu^{\otimes n}\) for a given measure \(\mu\).

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

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 ...

Génération de semis de points fractals : une méthode du comptage de boites inversée

Cybergeo, 2015
Fractal dimension is useful to characterize the structure of spatial objects such as urban structures or river networks. However, fractal analysis is underutilized for point processes.

Citizen Science Data Collection for Integrated Wildlife Population Analyses

Frontiers in Ecology and Evolution, 2021
Citizen science, or community science, has emerged as a cost-efficient method to collect data for wildlife monitoring. To inform research and conservation, citizen science sampling designs should collect data that match the robust statistical analyses ...

PCA for point processes

The Annals of Statistics
We introduce a novel statistical framework for the analysis of replicated point processes that allows for the study of point pattern variability at a population level. By treating point process realizations as random measures, we adopt a functional analysis perspective and propose a form of functional Principal Component Analysis (fPCA) for point ...

Satistical problems of point processes [PDF]

Mathematica Applicanda, 1978
This is a set of lectures delivered at the International Mathematical Centre, Warsaw, in 1976. The text contains three sections. Section 1 is devoted to basic notions. In the second section inference from a family of Poisson processes is considered. The last section deals with the problems of filtering of Cox processes (doubly stochastic processes).
