Flow cytometer apparatus for three dimensional difraction imaging and related methods
(2015-04-21)A flow cytometer assembly includes a fluid controller configured to form a hydrodynamically focused flow stream including an outer sheath fluid and an inner core fluid. A coherent light source is configured to illuminate ... -
Memory of Germinant Stimuli in Bacterial Spores
(2015-11)Bacterial spores, despite being metabolically dormant, possess the remarkable capacity to detect nutrients and other molecules in their environment through a biochemical sensory apparatus that can trigger spore germination, ... -

Realistic optical cell modeling and diffraction imaging simulation for study of optical and morphological parameters of nucleus
(2016-01)Coherent light scattering presents complex spatial patterns that depend on morphological and molecular features of biological cells. We present a numerical approach to establish realistic optical cell models for generating ... -
A new assessment model for tumor heterogeneity analysis with [18]F-FDG PET images
(2016-01)It has been shown that the intratumor heterogeneity can be characterized with quantitative analysis of the [18]F-FDG PET image data. The existing models employ multiple parameters for feature extraction which makes it ... -
Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
(East Carolina University, 2016-05-03)Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ... -
A NEW ELECTRON SPECTROSCOPY SYSTEM FOR MEASURING ELECTRON EMISSION FROM FAST ION INTERACTIONS WITH ATOMIC, MOLECULAR, AND CONDENSED PHASE TARGETS
(East Carolina University, 2016-07-25)A new electron spectroscopy system has been developed for measuring electron emission from gas and solid targets induced by fast ion impact. This system uses an ultrahigh-vacuum compatible cylindrical deflector analyzer, ...
