The study of atoms in extreme conditions has been the frontier of all science. The deeper scientists prod the structure of these building blocks the more questions there are. Often these questions are hypothesized through mathematical models for the better part of human history our mathematical proofs have far exceeded are physical experiments. An example […]
C56: Acoustic Impedance and Modeling Acoustic Impedance in a Trumpet Mouthpiece
The effect of acoustic impedance in any air-columns is accountable for the frequency of output sound. With noncylindrical air-columns, non-uniform cross-section area, the impedance varies continuously. An example of any instrument shows the complexity of varying impedance. In this research, advantage of having access to the impedance probe helped in developing experiment on determining the […]
C51: Calculation of Acoustic Impedance of a Clarinet
Acoustic impedance, one of the significant characteristics to describe the propagation of sound waves, can be simply defined as a ratio of acoustic pressure and resulting volume flow of air. To have a thorough understanding of acoustic impedance, in this project, we will conduct some calculations of the acoustic impedance of a clarinet and compare […]
CSII-02: A Study of the Trends in the Radiative Lifetime of Na2
Spectroscopy is a field which has been instrumental in furthering our understanding of extraterrestrial bodies and molecular architecture. A commonly utilized technique in spectroscopic research is to measure the radiative lifetimes of excited states, as it has been demonstrated to be effective in understanding the molecular structures. Predictive calculations shared by colleague Dr. Seth Ashman […]
A22: The Role of Metabolic Imaging in Cancers and Disease Diagnosis
We are two undergraduate researchers who study metabolic imaging methods with a focus on NAD(P)H conformations. The goal of our research is to review some of the different types of imaging strategies present for monitoring specific data about cellular metabolism. To summarize, we begin to answer the research question “what are the different types of […]
A23: Biomedical Applications of Sensing Multi-State Metabolic Behavior from Cellular Autofluorescence
One way to detect metabolic change in cells is through a method called laser-induced fluorescence spectroscopy which involves exciting the cellular sample using a laser and measuring the spectrum of its autofluorescence emission. In order to detect metabolic change, we monitor autofluorescence emission in real time, and through past studies we are able to quantify […]
B47: Physics Education: Introductory Student Self-Efficacy and Problem-Solving Approaches
Physics education research focuses on how to improve the effectiveness of student learning and curriculum development. This area of physics education specifically focuses on students in introductory physics courses and how their self-efficacy and problem-solving methods change over the course of a semester. By tracking the improvement or deterioration of a student’s abilities, the Miami […]
C52: Quantum Mechanical Anti-Lasers in Optical Cavities and Waveguides
First demonstrated in 2011, Coherent Perfect Absorption (CPA) is a robust technique to achieve perfect absorption when shining a coherent light on a loss medium with no apprent reflection, behaving just like an ideal blackbody. The technique is colloquially referred to as an “anti-laser”, for it is exatly the lasing process played backwards in time. […]
BRII-04: Towards Optics-Based Metabolic Sensing in Tissue
Optical techniques that measure endogenous fluorescence can provide useful information on the status of cellular metabolism, but extensions of these techniques to turbid media (such as tissue) are often complicated by a multitude of emission signals. Phasor analysis is class of analytical approaches used to monitor emission signals that has potential to simplify measurements in […]
