A Comparative Study of Sample Preparation for Staining and Immunodetection of Plant Cell Walls by Light Microscopy

open access: yesFrontiers in Plant Science, 2017
Staining and immunodetection by light microscopy are methods widely used to investigate plant cell walls. The two techniques have been crucial to study the cell wall architecture in planta, its deconstruction by chemicals or cell wall-degrading enzymes ...

Terminal embeddings

open access: yesTheoretical Computer Science, 2017
In this paper we study {\em terminal embeddings}, in which one is given a finite metric $(X,d_X)$ (or a graph $G=(V,E)$) and a subset $K \subseteq X$ of its points are designated as {\em terminals}. The objective is to embed the metric into a normed space, while approximately preserving all distances among pairs that contain a terminal.

Universes and simulations: Civilizational development in nested embedding

open access: yesFoundations of Computing and Decision Sciences, 2018
The rapid development of technology has allowed computer simulations to become routinely used in an increasing number of fields of science. These simulations become more and more realistic, and their energetic efficiency grows due to progress in computer

Mean-field embedding of the dual fermion approach for correlated electron systems [PDF]

open access: yes, 2013
To reduce the rapidly growing computational cost of the dual fermion lattice calculation with increasing system size, we introduce two embedding schemes. One is the real fermion embedding, and the other is the dual fermion embedding.

Survey of Neural Text Representation Models

open access: yesInformation, 2020
In natural language processing, text needs to be transformed into a machine-readable representation before any processing. The quality of further natural language processing tasks greatly depends on the quality of those representations.

Attention-Aware Heterogeneous Graph Neural Network

open access: yesBig Data Mining and Analytics, 2021
As a powerful tool for elucidating the embedding representation of graph-structured data, Graph Neural Networks (GNNs), which are a series of powerful tools built on homogeneous networks, have been widely used in various data mining tasks.

Embedded scalars [PDF]

open access: yesSemantics and Pragmatics, 2013
For over a decade, the interpretation of scalar expressions under embedding has been a much debated issue, with proposed accounts ranging from strictly pragmatic, on one end of the spectrum, to lexico-syntactic, on the other. There has been some confusion as to what exactly the controversy is about, and we argue that what is at stake is the division of

A procedure for correcting the position of plant tissue samples in accidentally polymerized glycol methacrylate resin

open access: yesHoehnea, 2019
Glycol methacrylate resin is a very convenient medium used for inclusions of various types of tissue for histological and cytological studies. It provides excellent mechanical support in the sectioning of samples, even the ones with big differences in ...
