X-ray phase-contrast CT of a pancreatic ductal adenocarcinoma mouse model. [PDF]

PLoS ONE, 2013
To explore the potential of grating-based x-ray phase-contrast computed tomography (CT) for preclinical research, a genetically engineered mouse model of pancreatic ductal adenocarcinoma (PDAC) was investigated.

The Cholewinski‐Fock space in the slice hyperholomorphic setting [PDF]

Mathematical Methods in the Applied Sciences, 2019
Inspired from the Cholewinski approach, we investigate a family of Fock spaces in the quaternionic slice hyperholomorphic setting as well as some associated quaternionic linear operators. In a particular case, we reobtain the slice hyperholomorphic Fock space on quaternions.

Growth Responses and Adventitious Root Formation of Cucumber Hybrid Lines in a Waterlogged Condition

Horticulturae, 2023
Cucumber (Cucumis sativus L.) F1 hybrids are grown commercially in open-field or greenhouse conditions. Hybrids are well adapted to these settings due to directed breeding.

Two-dimensional slices of non-pseudoconvex open sets [PDF]

Mathematische Zeitschrift, 2011
Let $D$ be a non-pseudoconvex open set in $\C^3$ and $S$ be the union of all two-dimensional planes with non-empty and non-pseudoconvex intersection with $D.$ Sufficient conditions are given for $\C^3\setminus S$ to belong to a complex line. Moreover, in the $\mathcal C^2$-smooth case, it is shown that $S=\C^n$.

Set Representation Learning with Generalized Sliced-Wasserstein Embeddings

, 2021
An increasing number of machine learning tasks deal with learning representations from set-structured data. Solutions to these problems involve the composition of permutation-equivariant modules (e.g., self-attention, or individual processing via feed-forward neural networks) and permutation-invariant modules (e.g., global average pooling, or pooling ...

Schur Functions and Their Realizations in the Slice Hyperholomorphic Setting [PDF]

Integral Equations and Operator Theory, 2011
we start the study of Schur analysis in the quaternionic setting using the theory of slice hyperholomorphic functions. The novelty of our approach is that slice hyperholomorphic functions allows to write realizations in terms of a suitable resolvent, the so called S-resolvent operator and to extend several results that hold in the complex case to the ...

Agnotology, Trustworthiness, and Uncertainty in the Presentation of Research Findings [PDF]

Human Research in Rehabilitation
As editors and scholars, we have a few serious concerns about the presentation of research findings in refereed journals. These concerns range from a lack of theoretical, research, or contextual foundation to misinterpretation of information to a ...

Guidelines for seismic sedimentologic study in non-marine postrift basins

Petroleum Exploration and Development, 2012
This study summarizes the research experiences of non-marine seismic sedimentology in recent years in China and uses Qijia area, Songliao Basin, as a template to establish general guidelines for seismic sedimentology.
