Spectroscopy of Rydberg atoms in non-neutral cold plasmas
No full textThe electric field in mm-sized one-component non-neutral plasmas is measured using the Stark effect of Rydberg atoms embedded in them. The plasmas are clouds of cold Rb+Rb+-ions, which are produced by UV photoionization of laser-cooled Rb atoms in a magneto-optic trap. The dependence of the electric field on the number of ions and the Coulomb explosion of the ion clouds have been studied. © 2002 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87634/2/89_1.pd
Small optic suspensions for Advanced LIGO input optics and other precision optical experiments
No full textWe report on the design and performance of small optic suspensions developed to suppress seismic motion of out-of-cavity optics in the input optics subsystem of the Advanced Laser Interferometer Gravitational Wave Observatory. These compact single stage suspensions provide isolation in all six degrees of freedom of the optic, local sensing and actuation in three of them, and passive damping for the other three
Report to Congress - Safe Havens: Supervised Visitation and Safe Exchange Services and Programs
No full textThis report provides the most thorough profile to date of supervised visitation and exchange programs in the United States, including information on types of services, common barriers to service, and the number of individuals being seen in these programs who experienced several forms of violence and abuse. Major findings include: a) dangerousness and unwillingness to agree to program rules limits acceptance for service; b) service is limited by capacity, hours, and transportation; c) family violence is one of the major reasons for supervised visitation; d) funding limitations are linked to safety needs.United States Department of Justice, Office on Violence Against Women (#2003 WT BX K043)http://deepblue.lib.umich.edu/bitstream/2027.42/115464/1/Safe Havens National Survey 2006 Report to Congress - 5-27-08 & author page.pdfDescription of Safe Havens National Survey 2006 Report to Congress - 5-27-08 & author page.pdf : Main Repor
Physics-Informed Extreme Theory of Functional Connections Applied to Optimal Orbit Transfer
No full textA novel and accurate physics-informed neural network method for solving differential equations, called the Extreme Theory of Functional Connections (or XTFC), is employed to solve optimal control problems. The proposed method is utilized in solving the system of differential equations resulting from the indirect method formulation of the optimal control problem, derived from the Hamiltonian function and applying the Pontryagin Maximum/Minimum Principle (PMP). The system of differential equations makes up the first order necessary conditions of the states and costates which in general produces a boundary value problem (BVPs) that is solved via X-TFC. According to the Theory of Functional Connections, the latent solutions are approximated with particular expansions, called constrained expressions. A constrained expression is a functional that both always satisfies the specified constraints and has a free-function that does not affect the specified constraints. In the X-TFC formulation, the free-function is a single-layer
NN, or more precisely, an Extreme Learning Machine (ELM). Using ELMs, the unknown coefficients appear linearly and therefore, a least-square approach (for linear problems) or an iterative least-square approach (for non-linear problems) is used to compute the unknowns by minimizing the residual of the system of differential equations. In this work, the approach is validated by solving the Feldbaum problem and optimal orbit transfer problems. It is shown the major benefit of this method is the low computational time along with comparable accuracy with respect to the state of the art methods

No full textGlobal health and foreign policy.
No full textHealth has long been intertwined with the foreign policies of states. In recent years, however, global health issues have risen to the highest levels of international politics and have become accepted as legitimate issues in foreign policy. This elevated political priority is in many ways a welcome development for proponents of global health, and it has resulted in increased funding for and attention to select global health issues. However, there has been less examination of the tensions that characterize the relationship between global health and foreign policy and of the potential effects of linking global health efforts with the foreign-policy interests of states. In this paper, the authors review the relationship between global health and foreign policy by examining the roles of health across 4 major components of foreign policy: aid, trade, diplomacy, and national security. For each of these aspects of foreign policy, the authors review current and historical issues and discuss how foreign-policy interests have aided or impeded global health efforts. The increasing relevance of global health to foreign policy holds both opportunities and dangers for global efforts to improve health
