Find, Process, And Share: An Optimal Control In The Vidale-Wolfe Marketing Model, Michael C. Barg

CODEE Journal

The Vidale-Wolfe marketing model is a first-order, linear, non-homogeneous ordinary differential equation (ODE) where the forcing term is proportional to advertising expenditure. With an initial response in sales as the initial condition, the solution of the initial value problem is straightforward for a first undergraduate ODE course. The model serves as an excellent example of many relevant topics for those students whose interests lie in economics, finance, or marketing. Its inclusion in the curriculum is particularly rewarding at an institution without a physics program. The model is not new, but it was novel to us when a group of students …

Preventing An Era Of "New Eugenics": An Argument For Federal Funding And Regulation Of Gene Editing Research In Human Embryos, Michael R. Dohn

Richmond Journal of Law & Technology

The 1997 film Gattaca is set in a futuristic society in which its members are either “valid,” born with the aid of genetic engineering, or “invalid", conceived by traditional means. While valids qualify for high-level professional employment, in-valids are considered less desirable by society and are relegated to menial jobs. At the time of the film’s release, this type of dystopian society, dominated by genetic engineering, seemed far into the future; however, only twenty years later, the concept of manipulating the genes of human embryos is near reality. The last decade has seen tremendous progression in gene editing technology. In …

Evidence For Terahertz Acoustic Phonon Parametric Oscillator Based On Acousto-Optic Degenerate Four-Wave Mixing In A Silicon Doping Superlattice, Thomas E. Wilson

Physics Faculty Research

We report evidence for a 1.0-THz self-starting mirrorless acoustic phonon parametric oscillator (MAPPO) produced from acousto-optic phase-conjugate degenerate four-wave (D4WM) mixing in a THz laser-pumped silicon doping superlattice (DSL). The DSL was grown by molecular beam epitaxy on a (100) boron-doped silicon substrate. A superconducting NbTiN subwavelength grating was used to couple the THz laser radiation into the DSL. Superconducting granular aluminum bolometric detection, coupled with Si:B piezophonon spectroscopy, revealed excitation of THz coherent compressional and shear waves, along the ⟨111⟩ direction only. The Bragg scattering condition for distributed feedback, and the energy conservation requirement for the D4WM process, were …

Meral Spot Total Reflectance Signals Weapon Performance In The Mantis Shrimp Neogonodactylus Oerstedii (Stomatopoda), Amanda M. Franklin, Cassandra M. Donatelli, Casey R. Culligan, Eric D. Tytell

Engineering Faculty Articles and Research

During animal contests over resources, opponents often signal their fighting ability in an attempt to avoid escalating to physical attack. A reliable signal is beneficial to receivers because it allows them to avoid injuries from engaging in contests they are unlikely to win. However, a signaler could benefit from deceiving an opponent by signaling greater fighting ability or greater aggressive intent than the signaler possesses. Therefore, the reliability of agonistic signals has long intrigued researchers. We investigated whether a colored patch, the meral spot, signals weapon performance in the stomatopod Neogonodactylus oerstedii. During fights over possession of refuges, stomatopods can …

A New Insight Into Underlying Disease Mechanism Through Semi-Parametric Latent Differential Network Model, Yong He, Jiadong Ji, Lei Xie, Xinsheng Zhang, Fuzhong Xue

Publications and Research

Background

In genomic studies, to investigate how the structure of a genetic network differs between two experiment conditions is a very interesting but challenging problem, especially in high-dimensional setting. Existing literatures mostly focus on differential network modelling for continuous data. However, in real application, we may encounter discrete data or mixed data, which urges us to propose a unified differential network modelling for various data types.

Results

We propose a unified latent Gaussian copula differential network model which provides deeper understanding of the unknown mechanism than that among the observed variables. Adaptive rank-based estimation approaches are proposed with the assumption …

Lifestyle Modifications: Coordinating The Trna Epitranscriptome With Codon Bias To Adapt Translation During Stress Responses, Cheryl Chan, Phuong Pham, Peter C. Dedon, Thomas J. Begley

Biological Sciences Faculty Scholarship

Cells adapt to stress by altering gene expression at multiple levels. Here, we propose a new mechanism regulating stress-dependent gene expression at the level of translation, with coordinated interplay between the tRNA epitranscriptome and biased codon usage in families of stress-response genes. In this model, auxiliary genetic information contained in synonymous codon usage enables regulation of codon-biased and functionally related transcripts by dynamic changes in the tRNA epitranscriptome. This model partly explains the association between synchronous stress-dependent epitranscriptomic marks and significant multi-codon usage skewing in families of translationally regulated transcripts. The model also predicts translational adaptation during viral infections.
