Single- and Multi-Frequency Direct Sampling Methods in a Limited-Aperture Inverse Scattering Problem

IEEE Access, 2020
Although the direct sampling method (DSM) has demonstrated its feasibility and robustness for imaging of small inhomogeneities, mathematical analyses of DSM have been conducted only on the full-aperture inverse scattering problem.

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 ...

Theoretical Identification of Coupling Effect and Performance Analysis of Single-Source Direct Sampling Method

Mathematics, 2021
Although the direct sampling method (DSM) has demonstrated its feasibility in identifying small anomalies from measured scattering parameter data in microwave imaging, inaccurate imaging results that cannot be explained by conventional research ...

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

A Direct Interpolation Method for Irregular Sampling

Applied and Computational Harmonic Analysis, 1999
In this paper the authors use a Lagrange-type interpolation formula (attributed to Boas and Bernstein, in this case) to estimate irregularly sampled band-limited functions. The interpolation formula uses only a finite number of neighbors, that number depending on the admissible truncation error. An estimate of the truncation error is established.

Sampling directed graphs with random walks [PDF]

2012 Proceedings IEEE INFOCOM, 2012
Despite recent efforts to characterize complex networks such as citation graphs or online social networks (OSNs), little attention has been given to developing tools that can be used to characterize directed graphs in the wild, where no pre-processed data is available.

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Direct sampling technique of bees on Vriesea philippocoburgii (Bromeliaceae, Tillandsioideae) flowers [PDF]

Biotemas, 2004
In our study on Vriesea philippocoburgii Wawra pollination, due to the small proportion of flowers in anthesis on a single day and the damage caused to inflorescences when netting directly on flowers, we used the direct sampling technique (DST) of bees ...

Direct Sampling in Air of Capillary Electrophoresis

Analytical Sciences, 2013
Capillary electrophoresis (CE) is usually off-line combined with an adsorption/desorption method to analyze gaseous or atmospheric samples. Here, we demonstrated direct sampling in the air of CE. The inlet end of a fused silica capillary filled with a pH 7.2 phosphate buffer was placed in the air for absorbing gaseous or volatile components, while the ...
