Cholesterol is carried and transported through bloodstream by lipoproteins. There are two types of lipoproteins: low density lipoprotein, or LDL, and high density lipoprotein, or HDL. LDL cholesterol is considered “bad” cholesterol because it can form plaque and hard deposit leading to arteries clog and make them less flexible. Heart attack or stroke will happen if the hard deposit blocks a narrowed artery. HDL cholesterol helps to remove LDL from the artery back to the liver.

Traditionally, particle counts of LDL and HDL plays an important role to understanding and prediction of heart disease risk. But recently research suggested that …

Manipulating The Mass Distribution Of A Golf Putter, Paul J. Hessler Jr. May 2015

Manipulating The Mass Distribution Of A Golf Putter, Paul J. Hessler Jr.

Senior Honors Projects

Putting may appear to be the easiest but is actually the most technically challenging part of the game of golf. The ideal putting stroke will remain parallel to its desired trajectory both in the reverse and forward direction when the putter head is within six inches of the ball. Deviation from this concept will cause a cut or sidespin on the ball that will affect the path the ball will travel.

Club design plays a large part in how well a player will be able to achieve a straight back and straight through club head path near impact; specifically the …


Quasielastic Scattering In The Interaction Of Ultracold Neutrons With A Liquid Wall And Application In A Reanalysis Of The Mambo I Neutron-Lifetime Experiment, Albert Steyerl, J. M. Pendlebury, Charles Kaufman, Surendra S. Malik, A. M. Desai Jun 2012

Quasielastic Scattering In The Interaction Of Ultracold Neutrons With A Liquid Wall And Application In A Reanalysis Of The Mambo I Neutron-Lifetime Experiment, Albert Steyerl, J. M. Pendlebury, Charles Kaufman, Surendra S. Malik, A. M. Desai

Physics Faculty Publications

We develop a theory of ultracold and very cold neutron scattering on viscoelastic surface waves up to second-order perturbation theory. The results are applied to reanalyze the 1989 neutron-lifetime experiment using ultracold neutron storage in a Fomblin-coated vessel by Mampe et al. [Phys. Rev. Lett. 63, 593 (1989)]. Inclusion of this theory of the quasielastic scattering process in the data analysis shifts the neutron lifetime value from 887.6 ± 3 to 882.5 ± 2.1 s.


Surface Roughness Effect On Ultracold Neutron Interaction With A Wall And Implications For Computer Simulations, Albert Steyerl, Surendra S. Malik, A. M. Desai, Charles Kaufman May 2010

Surface Roughness Effect On Ultracold Neutron Interaction With A Wall And Implications For Computer Simulations, Albert Steyerl, Surendra S. Malik, A. M. Desai, Charles Kaufman

Physics Faculty Publications

We review the diffuse scattering and the loss coefficient in ultracold neutron reflection from slightly rough surfaces, report a surprising reduction in loss coefficient due to roughness, and discuss the possibility of transition from quantum treatment to ray optics. The results are used in a computer simulation of neutron storage in a recent neutron lifetime experiment that reported a large discrepancy of neutron lifetime with the current particle data value. Our partial reanalysis suggests the possibility of systematic effects that were not included in this publication.


Algorithm For The Analysis Of Tryptophan Flourescence Spectra And Their Correlation With Protein Structural Parameters, John Hixon, Yana K. Reshetnyak Jan 2009

Algorithm For The Analysis Of Tryptophan Flourescence Spectra And Their Correlation With Protein Structural Parameters, John Hixon, Yana K. Reshetnyak

Physics Faculty Publications

The fluorescence properties of tryptophan residues are sensitive to the microenvironment of fluorophores in proteins. Therefore, fluorescence characteristics are widely used to study structural transitions in proteins. However, the decoding of the structural information from spectroscopic data is challenging. Here we present a review of approaches developed for the decomposition of multi-component protein tryptophan fluorescence spectra and correlation of these spectral parameters with protein structural properties.


Accurate Analysis Of Tumor Margins Using A Fluorescent Ph Low Insertion Peptide (Phlip), James Segala, Donald M. Engelman, Yana K. Reshetnyak, Oleg A. Andreev Jan 2009

Accurate Analysis Of Tumor Margins Using A Fluorescent Ph Low Insertion Peptide (Phlip), James Segala, Donald M. Engelman, Yana K. Reshetnyak, Oleg A. Andreev

Physics Faculty Publications

The recurrence of certain cancers remains quite high due to either incomplete surgical removal of the primary tumor or the presence of small metastases that are invisible to the surgeon. Near infrared (NIR) fluorescence imaging might improve surgical outcomes by providing sensitive, specific, and real-time visualization of normal and diseased tissues if agents can be found that discriminate between normal and diseased tissue and define tumor margins. We have developed a new approach for revealing tumor borders by using NIR fluorescently labeled pH Low Insertion Peptide (pHLIP) and have created a computational program for the quantitative assessment of tumor boundaries. …


Summary Of The Workshop On The Applications Of X-Ray Standing Waves In Studies Of Surfaces, Fiims, And Buik Materiais, David R. Heskett, L. Berman Feb 1995

Summary Of The Workshop On The Applications Of X-Ray Standing Waves In Studies Of Surfaces, Fiims, And Buik Materiais, David R. Heskett, L. Berman

Physics Faculty Publications

Highlights of the satellite workshop on the technique of x-ray standing waves which preceded the 5th International Conference on Synchrotron Radiation Instrumentation held at the State University of New York at Stony Brook, USA are presented. At the workshop, many applications of the x-ray standing-wave technique were described in both invited and contributed talks. While the predominant use of the XSW technique was to analyze the structure of adsorbates on surfaces, applications in the characterization of thin films, interfaces, clean surfaces, and bulk materials were also presented. Most of the talks concentrated on experimental results, but some theory was also …
