MODIFIED CELLS AS MULTIMODAL STANDARDS FOR CYTOMETRY AND SEPARATION
Inline classification of a biological specimen including mammalian cells can include generating an alternating current (AC) electrical stimulus to an electrode structure. The electrode structure can be electrically coupled with a flow cell. A response, elicited by the electrical stimulus, can be received when a model specimen class traverses the flow cell. Using the received response, a corresponding impedance parameter value can be determined, the value indicative of a specified biophysical characteristic corresponding to the model specimen class. The first impedance parameter can be translated to a value corresponding to the specified biophysical characteristic.
PARTICLE MEASURING DEVICE AND PARTICLE MEASURING METHOD
To enable evaluation of a shape of a fine particle and a fine particle type, a substrate is set as a substrate on which an isolated fine particle to be measured and an isolated standard fine particle in the vicinity of the isolated fine particle to be measured are disposed, and a scanning electron microscope body including a detector configured to detect secondary charged particles obtained by scanning a surface of the substrate with an electron beam probe, and a computer that processes a detection signal and generates an image of the isolated fine particle to be measured and the isolated standard fine particle are provided. The computer corrects a shape of the isolated fine particle to be measured by using a measurement result of the isolated standard fine particle disposed in the vicinity of the isolated fine particle to be measured. Further, by attaching a fine particle spreading tank equipped with a fine particle suspension dropping device inside the microscope body, automatic measurement including dropping of fine particle suspension onto a surface of a surface-modified substrate is possible.

Method and system for predicting engine performance
Systems and methods for predicting engine performance are provided herein. A fluid sample having particles suspended therein is received from a first engine. A plurality of particles are extracted from the fluid sample.
