PROBLEM TO BE SOLVED: To provide a method of the pretreatment of a biological sample for investigating the distribution of medicine in a biological sample and quantifying the medicine in the biological sample using a matrix support laser desorption ionization method (MALDI).SOLUTION: The sample ...
The mass spectrum of a complex mixture is very difficult to fully analyze due to its overwhelming number of components. This problem is exacerbated by enzymatic digestion of a protein sample into a large number of peptide products. ...
4.4.1 Sample mass The minimum mass of sample collected needs to be sufficient to meet the requirements of sampling precision for analytes of concern, for example, ash%. For general analysis, including ash%, ISO 13909-4 provides a table of samples masses for a range of top sizes (Table 4.9...
PROBLEM TO BE SOLVED: To obtain a method for setting a to-be-measured element with more improved handling convenience by intuitively conducting an inputting operation necessary to select by an operator, displaying detail information for the selection, and visually confirming a mass number range of ...
Linear programing models for portfolio optimization using a benchmark We consider the problem of constructing a perturbed portfolio by utilizing a benchmark portfolio. We propose two computationally efficient portfolio optimi... S Park,H Song,S Lee - 《European Journal of Finance》 被引量: 0发表:...
Water, like any pure chemical compound, has a definite mass-mole correspondence or conversion. The correspondence or conversion factor is the molar mass of water. A mole of water constitutes 6.02×1023 molecules. This is true of a mole of any substance. In fact,...
No explicit cost for each observation was taken, i.e., c = 0. The sample distribution was unknown to the DM. A reward was paid only when the card with the highest number was selected, and nothing otherwise. This describes a decision situation that is known as the secretary problem (a ...
A central problem in parameterized algorithms is to obtain algorithms with running time f (k) * nO(1) such that f is as slow growing a function of the para... D Lokshtanov†,DN Marx‡,S Saurabh§ - Acm-siam Symposium on Discrete Algorithms 被引量: 198发表: 2011年 ...
Comparison of methods for the estimation of statistical parameters of censored data statistics are described and evaluated for the estimation of the mean and standard deviation of a normal population from a left-singly censored sample, i... S Kuttatharmmakul,DL Massart,D Coomans,... - 《Analyti...
sample and crucible material. Stress relaxation can lead to the crucible moving slightly on the sensor, which produces artifacts on the DSC curve. The example above shows that this potential problem can be overcome with appropriate sample preparation and in particular by using smaller sample masses....
