Improvements in Epoxy Resin Embedding Methods
Epoxy embedding methods of Glauert and Kushida have been modified so as to yield rapid, reproducible, and convenient embedding methods for electron microscopy. The sections are robust and tissue damage is less than with methacrylate embedding.
متن کاملGeneralized De-embedding Techniques
This paper discusses techniques for embedding and de-embedding the characteristics of two-port devices described by scattering parameters at microwave frequencies. Such techniques have wide applications in areas such as the measurement of the parameters of a semiconductor device mounted in a fixture, removal of the effects of cables, adapters, etc. and network analyzer calibration using variant...
متن کاملA New Document Embedding Method for News Classification
Abstract- Text classification is one of the main tasks of natural language processing (NLP). In this task, documents are classified into pre-defined categories. There is lots of news spreading on the web. A text classifier can categorize news automatically and this facilitates and accelerates access to the news. The first step in text classification is to represent documents in a suitable way t...
متن کاملA routine method for embedding animal tissues in Spurr resin for electron microscopy.
The epoxy resin epon 812 has been used in this department to embed a variety of normal and pathological tissues for a number of years. Unfortunately during the past 18 months sectioning qualities of polymerized epon blocks have become variable in an unpredictable manner. It is possible that the batch variation in the quality and composition of the dodecynl succinic anhydride (DDSA) could be res...
متن کاملLx = b
Preface The ability to solve a system of linear equations lies at the heart of areas such as optimization, scientific computing and computer science and, traditionally, has been a central topic of research in numerical linear algebra. Consider a system Ax = b with n equations in n variables. Broadly, solvers for such a system of equations fall into two categories. The first is Gaussian eliminat...
