Book Review: Hewitt, Nancy A. Women\u27s Activism And Social Change: Rochester, New York, 1822-1872

Scholar Nancy A. Hewitt analyzes the lives of women in antebellum Rochester, New York, focusing how they adapted to a wide variety of changes during a turbulent period in American history

Capturing Memory

In my work, I present the moments of true emotional clarity and impactful memories from my life. I strive to provide insight into my experiences and my understanding of others’ motivations. The creative process helps safely guide me through memories of the past and understanding of others. In my abstracted mixed media paintings and crafts, I use bold jewel tones to express strong feelings and passionate emotions. I also incorporate found objects and paints to communicate the layers and varied depth of memories. With the use of these varied materials, I have developed a personal symbolic language that allows me to relay aspects of my life and perceptions. My goal is to explore my past and invite the viewer into my experiences

A Bayesian Estimator for Linear Calibration Error Effects in Thermal Remote Sensing

The Bayesian Land Surface Temperature estimator previously developed has been extended to include the effects of imperfectly known gain and offset calibration errors. It is possible to treat both gain and offset as nuisance parameters and, by integrating over an uninformative range for their magnitudes, eliminate the dependence of surface temperature and emissivity estimates upon the exact calibration error.Comment: 3 page

Exotic Addiction

With an annual profit between $10 and$20 billion, animal smuggling has become the third largest illegal trade in the world, behind only drugs and firearms, and the results are devastating to humans and animals alike. Zoonotic diseases are spreading, animal attack incidents are increasing, and several species are rapidly approaching extinction. This raises several questions that have been largely unanswered: What is causing the increase in demand? How serious are the effects? Why isn’t the law effective in preventing this? What can be done to slow this trend? This Comment attempts to answer these questions by investigating the causes and effects of this multi-billion dollar industry and the legal loopholes that allow it to flourish, and offers suggestions on how the law could be improved to address these challenges

Non-adiabatic transitions in multi-level systems

In a quantum system with a smoothly and slowly varying Hamiltonian, which approaches a constant operator at times $t\to \pm \infty$, the transition probabilities between adiabatic states are exponentially small. They are characterized by an exponent that depends on a phase integral along a path around a set of branch points connecting the energy level surfaces in complex time. Only certain sequences of branch points contribute. We propose that these sequences are determined by a topological rule involving the Stokes lines attached to the branch points. Our hypothesis is supported by theoretical arguments and results of numerical experiments.Comment: 25 pages RevTeX, 9 figures and 4 tables as Postscipt file

Coupling Rydberg atoms to microwave fields in a superconducting coplanar waveguide resonator

Rydberg helium atoms traveling in pulsed supersonic beams have been coupled to microwave fields in a superconducting coplanar waveguide (CPW) resonator. The atoms were initially prepared in the 1s55s $^3$S$_1$ Rydberg level by two-color two-photon laser excitation from the metastable 1s2s $^3$S$_1$ level. Two-photon microwave transitions between the 1s55s $^3$S$_1$ and 1s56s $^3$S$_1$ levels were then driven by the 19.556 GHz third-harmonic microwave field in a quarter-wave CPW resonator. This superconducting microwave resonator was fabricated from niobium nitride on a silicon substrate and operated at temperatures between 3.65 and 4.30 K. The populations of the Rydberg levels in the experiments were determined by state-selective pulsed electric field ionization. The coherence of the atom-resonator coupling was studied by time-domain measurements of Rabi oscillations.Comment: 6 pages, 5 figure

Ultraviolet response of film candidates for the solar optical telescope photometric filtergraph

Measurements of UV response between 2000 and 3000 A of Kodak films 2415, Aerocon II 3412, and SO-415 are reported. The short wavelength cutoff of the response of all films studied lies near 2100 A, occurring as a gentle falloff starting near 2500 A. The sensitivity of the films appears to remain roughly constant from 2500 to 3000 A. Estimates of UV Gamma for 2415 and the effect of hard UV on the optics in the experiment are also discussed
