Macroscopic Entanglement by Entanglement Swapping
We present a scheme for entangling two micromechanical oscillators. The
scheme exploits the quantum effects of radiation pressure and it is based on a
novel application of entanglement swapping, where standard optical measurements
are used to generate purely mechanical entanglement. The scheme is presented by
first solving the general problem of entanglement swapping between arbitrary
bipartite Gaussian states, for which simple input-output formulas are provided.Comment: 4 pages, 2 figures, RevTe
Melody based tune retrieval over the World Wide Web
In this paper we describe the steps taken to develop a Web-based version of an existing stand-alone, single-user digital library application for melodical searching of a collection of music. For the three key components: input, searching, and output, we assess the suitability of various Web-based strategies that deal with the now distributed software architecture and explain the decisions we made. The resulting melody indexing service, known as MELDEX, has been in operation for one year, and the feed-back we have received has been favorable
Complete spatial characterization of an optical wavefront using a variable-separation pinhole pair
We present a technique for measuring the transverse spatial properties of an
optical wavefront. Intensity and phase profiles are recovered by analysis of a
series of interference patterns produced by the combination of a scanning
X-shaped slit and a static horizontal slit; the spatial coherence may be found
from the same data. We demonstrate the technique by characterizing high
harmonic radiation generated in a gas cell, however the method could be
extended to a wide variety of light sources.Comment: 4 pages, 3 figures, 1 tabl
Effectiveness of sensory modulation in treating sensory modulation disorders in adults with schizophrenia: a Systematic Literature Review
Sensory modulation, as a treatment for sensory modulation disorders in adults with psychiatric conditions, has been implemented by occupational therapists for more than two decades. The purpose of this systematic literature review was to evaluate published research evidence relating to this intervention. The aim of the study was to determine if there was established evidence for the effectiveness of sensory modulation in treating sensory modulation disorder in adults with schizophrenia and to identify any gaps in knowledge to guide further research. We utilized Australia’s National Health and Medical Research Council (NHMRC)’s levels of evidence and recommendation grading and the Rosalind Franklin Research Appraisal Instrument (RF-QRA) to review selected articles. The results were then summarized and reported utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. A total of 17 studies were included in the study. We concluded that there is preliminary evidence for the existence of sensory modulation disorder in schizophrenia and the effectiveness of sensory modulation interventions for reducing distress. We recommended further studies on the effectiveness of sensory modulation with better rigor and advise that guidelines be developed for use in practice by clinicians.Griffith Health, School of Applied PsychologyNo Full Tex
There’s Something in the Water: Toxic Exposure Liability of Public Water Suppliers in the Face of Near-Universal PFAS Exposure
California has not experienced the type of willful, large-scale PFAS pollution that states that hosted its manufacture, such as Ohio and West Virginia, have endured. Regardless, the ubiquity of these chemicals in California’s food and water supply, combined with a growing awareness of the serious health risks of PFAS exposure, prompted California to become a nationwide leader in PFAS regulation. In 2017, the California Office of Environmental Health Hazard Assessment (OEHHA) “added PFOA and PFOS to the Proposition 65 list of chemicals known to the state to cause reproductive toxicity” without setting a “maximum allowable dose level, below which no Proposition 65 warning is required.” California then passed A.B. 756 in July 2019, which empowered the State Water Resources Control Board (SWRCB) to force public water suppliers (PWS) to monitor for PFAS compounds. The SWRCB has since set the strictest monitoring levels for PFOA and PFOS in the nation. With more research being done on the adverse health effects of exposure to these chemicals, there is a growing possibility that PWSs with contaminated water sources may be exposed to toxic tort suits brought by consumers.
The first section of this Article will discuss the physical and environmental properties of PFAS compounds and current research into their toxicity, while the second section will discuss pre-A.B. 756 efforts by the federal government and California to regulate PFAS. The third section will analyze the provisions of A.B. 756. The fourth section will then apply the landmark toxic tort recovery framework from Potter v. Firestone Tire & Rubber Co. to explore the viability of potential toxic tort claims against PWSs, such as negligent infliction of emotional distress and fear of cancer, as well as the defense of sovereign immunity. The fifth section will discuss final thoughts on the viability of implementing A.B. 756
