    Secrecy in the American Revolution

    Full text link
    This paper analyzes how the use of various cryptographic and cryptanalytic techniques affected the American Revolution. By examining specific instances of and each country\u27s general approaches to cryptography and cryptanalysis, it is determined that America\u27s use of these techniques provided the rising nation with a critical advantage over Great Britain that assisted in its victory

    Werner state structure and entanglement classification

    Full text link
    We present applications of the representation theory of Lie groups to the analysis of structure and local unitary classification of Werner states, sometimes called the {\em decoherence-free} states, which are states of nn quantum bits left unchanged by local transformations that are the same on each particle. We introduce a multiqubit generalization of the singlet state, and a construction that assembles these into Werner states.Comment: 9 pages, 2 figures, minor changes and corrections for version

    Quantum Turbulent Structure in Light

    Full text link
    The infinite superpositions of random plane waves are known to be threaded with vortex line singularities which form complicated tangles and obey strict topological rules. We observe that within these structures a timelike axis appears to emerge with which we can define vortex velocities in a useful way: with both numerical simulations and optical experiments, we show that the statistics of these velocities match those of turbulent quantum fluids such as superfluid helium and atomic Bose-Einstein condensates. These statistics are shown to be independent of system scale. These results raise deep questions about the general nature of quantum chaos and the role of nonlinearity in the structure of turbulence.Comment: 4 pages, 2 figure

    Effects of Childhood Cancer and Hospitalization on Preschool Aged Children: Benefits of Movement Programming in Child Life Departments

    Child Life departments have been prominent in most children‘s hospitals to provide psychosocial care for children experiencing time in a hospital environment. This presentation will demonstrate the impact of Child Life intervention in pediatric oncology as well as promote new ideas for movement/dance therapy Child Life programming. New methods for healthcare therapies have been rapidly increasing especially in cancer treatment centers. The creative arts have been implemented into pediatric hospitals as a form of therapy for children and families undergoing treatments. The overview of play therapy and the developmental purpose it provides for preschool aged children is essential to understand why it is important to have in an environment such as the hospital. Play therapy is a new and upcoming type of therapy that focuses on helping children understand and deal with issues triggered from being hospitalized. Through play and the creative arts children are able to cope, portray their fears and anxieties, and have a sense of normalization. Children‘s Hospitals use this technique to help children cope with their illnesses in and outside of their time in the hospital. New perspectives on play therapy and ideas on how to tie in movement/dance therapy to greater benefit the Child Life department are offered through this research

    Effects of Childhood Cancer and Hospitalization on Preschool Aged Children: Benefits of Play Therapy and Movement Therapy

    Child life departments have been prominent in most children’s hospitals to provide psychosocial care for children experiencing time in a hospital environment.

    Rounding Up the Three-Fifths Clause: Eradicating Prison Gerrymandering in the South

    Get PDF
    This Comment examines the phenomenon of prison gerrymandering, a practice that involves counting prisoners as residents of the counties where their state correctional facilities are located—rather than in their home communities—for redistricting and representational purposes. This practice of counting inflates the voting power of rural, white districts with large prison complexes and diminishes the voting power of minority communities. Prison gerrymandering has become especially pervasive across southern states while many of the South’s northern counterparts have eradicated this practice through legislative reform. This Comment proposes a solution to stop prison gerrymandering in the South, arguing a strategy to produce a circuit split to prime the Supreme Court to address the constitutionality of prison gerrymandering. The Comment covers a variety of topics that either directly or indirectly contribute to prison gerrymandering, such as the Three-Fifths Compromise, the Census Bureau’s “usual residence rule,” sentencing disparities, felon disenfranchisement, and malapportionment claims

    Controls on Joint Formation During Glacial Unloading of the Sharon Sandstone at Gorge Metropark, Akron, Ohio

    The transition between significantly different materials is known to inhibit crack propagation, i.e. automobile glass, machinable ceramics and joints in different lithologies. In order to determine if a significant material transition, or a surface, such as a bedding plane, has a greater impact on inhibiting joint formation, I investigated discontinuous joints that formed during glacial unloading of the Sharon Sandstone, which is exposed at Gorge Metropark in Akron, Ohio. The Sharon Sandstone is a medium grained quartz arenite of Early Pennsylvanian age with significant cross-bedding, and contains many continuous (i.e. through-going), and discontinuous, joints in similar orientations. Stress fields created by unloading during glacial retreat following the last glacial maximum influenced joint orientations, spacing, and termination. 50% of the discontinuous joints observed terminated randomly within the outcrop, 20% terminated at free surfaces created by other joint sets, and 30% terminated at bedding planes. These results indicate that stress relaxation caused by joint formation exerts a larger control on joint termination than bedding planes or other surfaces in moderately homogenous rocks

    Interpersonal emotion regulation: a review of social and developmental components

    Full text link
    A staple theme in clinical psychology, emotion regulation, or the ability to manage one's emotions, is directly linked with personal wellbeing and the ability to effectively navigate the social world. Until recently, this concept has been limited to a focus on intrapersonal processes, such as suppression. Less emphasis has been placed on developmental, social, and cultural aspects of emotion regulation. We argue here that as social beings, our engagement in emotion regulation may often occur interpersonally, with trusted others helping us to regulate our emotions. This review will highlight recent research on interpersonal emotion regulation processes.Dr Hofmann receives financial support from the Alexander von Humboldt Foundation (as part of the Humboldt Prize), NIH/NCCIH (R01AT007257), NIH/NIMH (R01MH099021, U01MH108168), and the James S.
