Angles, Triangle Inequalities, Correlation Matrices and Metric-Preserving and Subadditive Functions Linear Algebra and its Applications (2016)
We present inequalities concerning the entries of correlation matrices, density matrices, and partial isometries through the positivity of 3×3 matrices. We extend our discussions to the inequalities concerning the triangle triplets with metric-preserving and subadditive ...
Basic Neuron Model Electrical Equivalent Circuit: An Undergraduate Laboratory Exercise Journal of Undergraduate Neuroscience Education (2013)
We developed a hands-on laboratory exercise for undergraduate students in which they can build and manipulate a neuron equivalent circuit. This exercise uses electrical circuit components that resemble neuron components and are easy to construct. ...
Can a Road-Driven Car Outrace a Free-Falling Car? European Journal of Physics (2011)
Motivated by an advertising scenario in which a luxury sports sedan races against a similar car falling under the influence of gravity, a calculation using undergraduate physics and calculus is performed to theoretically predict the ...
b→Sγ Constraints on the Minimal Supergravity Model with Large tanβ Physical Review D (1998)
In the minimal supergravity model (MSUGRA), as the parameter tanβ increases, the charged Higgs boson and light bottom squark masses decrease, which can potentially increase contributions from tH±, ̃gbj and Zibj loops in the decay ...
Naturalness Lowers the Upper Bound on the Lightest Higgs boson Mass in Supersymmetry Physical Review D (1997)
We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymmetric Higgs boson mass. We find ...
Constraints on the Minimal Supergravity Model from Non-Standard Vacua Physical Review D (1996)
We evaluate regions of parameter space in the minimal supergravity model where "unbounded from below" (UFB) or charge or color-breaking minima (CCB) occur. Our analysis includes the most important terms from the one-loop effective potential. ...
Naturalness and Superpartner Masses or When to Give Up on Weak Scale Supersymmetry Physical Review D (1995)
Superpartner masses cannot be arbitrarily heavy if supersymmetric extensions of the standard model explain the stability of the gauge hierarchy. This ancient and hallowed motivation for weak scale supersymmetry is often quoted, yet no reliable ...
Measure of Fine Tuning Physics Letters B (1995)
Fine-tuning criteria are frequently used to place upper limits on the masses of superpartners in supersymmetric extensions of the standard model. However, commonly used prescriptions for quantifying naturalness have some important shortcomings. Motivated by this, ...
Challenging Weak-Scale Supersymmetry at Colliders Physical Review D (1995)
Experimental searches for supersymmetry are entering a new era. As future experiments explore the mass range above the current lower bounds on superpartner masses, a failure to observe signals of superpartner production will begin to ...
Discrete Symmetries and Isosinglet Quarks in Low-Energy Supersymmetry Physics Letters B (1994)
Many extensions of the minimal supersymmetric standard model contain superfields for quarks which are singlets under weak isospin with electric charge -13. We explore the possibility that such isosinglet quarks have low or intermediate scale ...
Renormalization Group Study of the Standard Model and its Extensions: The Minimal Supersymmetric Standard Model Physical Review D (1994)
In this paper we summarize the minimal supersymmetric standard model as well as the renormalization group equations of its parameters. We proceed to examine the feasibility of the model when the breaking of supersymmetry is ...
Mass and Mixing-Angle Patterns in the Standard Model and its Minimal Supersymmetric Extension Physical Review D (1993)
Using renormalization group techniques, we examine several interesting relations among masses and mixing angles of quarks and leptons in the standard model. We extend the analysis to the minimal supersymmetric extension to determine its effect ...
Renormalization-Group Study of the Standard Model and its Extensions: The Standard Model Physical Review D (1992)
In this paper we present a comprehensive analysis of the running of all the couplings of the standard model to two loops, including threshold effects. Our purpose is twofold—to determine what the running of these ...
Top-Quark and Higgs-Boson Mass Bounds from a Numerical Study of Supersymmetric Grand Unified Theories Physical Review Letters (1991)
We run all the couplings of the minimal supersymmetric (SUSY) extension of the standard model, taking account of the Yukawa sector. After identifying the scale at which the gauge couplings unify, we place bounds on ...
Aerosol Analysis with the Coastal Zone Color Scanner: A Simple Method for Including Multiple Scattering Effects Applied Optics (1989)
For measurement of aerosols over the ocean, the total radiance Lt backscattered from the top of a stratified atmosphere which contains both stratospheric and tropospheric aerosols of various types has been computed. A similar computation ...
Coastal Zone Color Scanner Atmospheric Correction Algorithm: Multiple Scattering Effects Applied Optics (1987)
An analysis of the errors due to multiple scattering which are expected to be encountered in application of the current Coastal Zone Color Scanner (CZCS) atmospheric correction algorithm is presented in detail. This was prompted ...

Chapter 1: Physics Overview of Solar Energy Chemistry and Physics Faculty Books and Book Chapters (2013)
Undoubtedly the most important factor in the study of solar energy is the sun, the local star and the gravitational stake to which the earth is tethered. The standard theories of particle physics and cosmology ...
