An Alternative Proof of Hesselholt's Conjecture on Galois Cohomology of Witt Vectors of Algebraic Integers
Let be a complete discrete valuation field of characteristic zero with
residue field of characteristic . Let be a finite Galois
extension with Galois group G=\Gal(L/K) and suppose that the induced
extension of residue fields is separable. Let
denote the ring of -typical Witt vectors of length . Hesselholt
conjectured that the pro-abelian group
is isomorphic to zero.
Hogadi and Pisolkar have recently provided a proof of this conjecture. In this
paper, we provide an alternative proof of Hesselholt's conjecture which is
simpler in several respects.Comment: 3 pages; added references, changed Remark 2.1 to a lemma and proof,

Could Data Broker Information Threaten Physician Prescribing and Professional Behavior?
Privacy is threatened by the extent of data collected and sold by consumer data brokers. Physicians, as individual consumers, leave a ‘data trail’ in the offline (e.g. through traditional shopping) and online worlds (e.g. through online purchases and use of social media). Such data could easily and legally be used without a physician’s knowledge or consent to influence prescribing practices or other physician professional behavior. We sought to determine the extent to which such consumer data was available on a sample of more than 3,000 physicians, healthcare faculty and healthcare system staff at one university’s health units. Using just work email addresses for these employees we cheaply and quickly obtained external data on nearly two thirds of employees on demographic characteristics (e.g. income, top 10% national wealth, children at home, married), purchases (e.g. baby products, cooking, sports), behavior (e.g. charitable donor, discount shopper) and interests (e.g. automotive, health and wellness). Consumer data brokers have valuable, cost-effective and detailed information on many healthcare professionals, including data that could be used to segment, target, detail and generally market to physicians in ways that seem under‐appreciated. We call for greater attention to this potential aspect of physician-industry relationships
Frequency Following Imaging of Electric Fields from Resonant Superconducting Devices using a Scanning Near-Field Microwave Microscope
We have developed a scanning near-field microwave microscope that operates at
cryogenic temperatures. Our system uses an open-ended coaxial probe with a 200
mm inner conductor diameter and operates from 77 to 300 K in the 0.01-20 GHz
frequency range. In this paper, we present microwave images of the electric
field distribution above a Tl2Ba2CaCu2O8 microstrip resonator at 77 K, measured
at several heights. In addition, we describe the use of a frequency-following
circuit to study the influence of the probe on the resonant frequency of the
device.Comment: 4 pages, postscript file with 6 figures conference proceeding for the

William Shakespeare as a Purveyor of Re-Productions: Understanding Shakespeare’s Plays as Profitable Products
This project, “Recasting William Shakespeare in The Business of Playwriting,” works to reinvigorate the value gained by reading Shakespeare by: Beginning with espousing the importance of reading Shakespeare as a practical businessman first, instead of the mythological literary genius that men decades and now centuries after Shakespeare marketed and herald him as. Although this is not the primary focus of this paper, it is an important framework that begins to enable us to shift our presumptions of the canonical text, Romeo and Juliet . The next section sets the backdrop, i.e. the environment, in which Shakespeare used an emerging profession to recreate literature and runs through the “ancestry” of the star-crossed lovers archetype. Finally, the main section of this project identifies and explicates particular loci where Shakespeare transformed the original text in order to target and appeal to the audience of the times; in particular to Romeo & Juliet , this includes that of the creation of suspense, tragedy in relation to comedy, and an interrogation of love at first sight. This project concludes with a quick review of other proof of audience recognition within Shakespeare’s corpus that can lead to further investigations and close readings of other texts, Shakespearean or not, for financial motivations.
All of which will help readers of Shakespeare come away with a greater business appreciation of his work and possibly force readers to think about the economic constraints and incentives shaping literature
