History of the APL Colloquium, Covering Its First Four Decades Through 1988, Has Been Previously Described in the Technical Digest D. m. siLVer The ApL colloquium David M. Silver The ApL Colloquium has been a 59-year tradition at the Laboratory. The lectures are held weekly, generally from October to May, and cover an eclectic range of topics. The early history of the ApL Colloquium, covering its first four decades through 1988, has been previously described in the Technical Digest. The present article highlights some of the history of the institution and provides a chronological inventory of the colloquium lectures from 1988 to 2006.

  • Johns Hopkins University Style Guide Contents Introduction Names
    JHU Office of Communications Style Guide page 1 Johns Hopkins University Style Guide Contents • Introduction • Names: Johns Hopkins University and its divisions • Style guidelines Introduction These guidelines were compiled by editors in the Office of Communications to encourage consistency and correct usage of terms across the many publications produced by JHU offices. The guidelines draw from The Associated Press Stylebook 2019 and the 17th edition of The Chicago Manual of Style. Written from a Johns Hopkins point of view, the guidelines are intended to complement AP and CMOS and, when those sources disagree, to choose between them. For points not addressed in the university guidelines, AP is the preferred source. For points not listed in AP, use the dictionary it recommends: Webster’s New World College Dictionary. When the dictionary gives two spellings, use the first one; when the dictionary and AP give different spellings, use AP’s. A number of individual JHU publications have their own style sheets, more detailed and directed to handling specialized content. Johns Hopkins Medicine, for example, has posted its Branding and Use of Name Toolkit http://brand.hopkinsmedicine.org/gui/content.asp. The guidelines below will supplement those already existing and will contribute to the effort to bring overall consistency to university publications. Names: Johns Hopkins University and its divisions The Johns Hopkins University/The Johns Hopkins Hospital: The preferred shortened name for Johns Hopkins University is Johns Hopkins, not Hopkins. The acronym JHU can be used as a shortened form in informal or internal communications and to avoid repetition of the Hopkins name.

  • So, Has Voyager 1 Left the Solar System? Scientists Face Off Cosmic-Ray Fluctuations Could Mean the Craft Has Exited the Sun's Magnetic Field
    NATURE | NEWS So, has Voyager 1 left the Solar System? Scientists face off Cosmic-ray fluctuations could mean the craft has exited the Sun's magnetic field. Ron Cowen 21 March 2013 A space physicist this week suggests that NASA’s venerable Voyager 1 spacecraft has become the first vehicle to venture beyond the heliosphere — the magnetic bubble created by the Sun — but other mission scientists disagree. William Webber of New Mexico State University in Las Cruces bases the claim on signals recorded last August by the Voyager 1 cosmic-ray subsystem — a device that he helped to build — along with his late colleague and study co-author Francis McDonald. JPL-Caltech/NASA Voyager 1 recorded a sudden drop in cosmic rays The instrument recorded a dramatic drop in the intensity of the cosmic rays trapped last August, a possible sign that it had left the in the Sun’s magnetic field and a concomitant rise in that of rays generated by more Sun's sphere of influence. distant reaches of the Galaxy. That pattern indicates that Voyager 1 has travelled beyond the Sun’s magnetic influence and is no longer being shielded from galactic cosmic rays, the researchers report in a study published online this week in Geophysical Research Letters1. But if one is to believe a press release issued by NASA on 20 March (the same day the report was published), the two researchers jumped the gun. Other Voyager scientists who analysed the same data last autumn reiterate what they said then: the cosmic-ray data indicate that Voyager 1 is in a transition zone within the outer part of the heliosphere, but until a dramatic change in magnetic-field intensity and direction is detected, the craft remains firmly within the Sun’s magnetic sphere of influence.

  • Probabilistic Models on Fibre Bundles by Shan Shan
    Probabilistic Models on Fibre Bundles by Shan Shan Department of Mathematics Duke University Date: Approved: Ingrid Daubechies, Supervisor Sayan Mukherjee, Chair Doug Boyer Colleen Robles Dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Mathematics in the Graduate School of Duke University 2019 ABSTRACT Probabilistic Models on Fibre Bundles by Shan Shan Department of Mathematics Duke University Date: Approved: Ingrid Daubechies, Supervisor Sayan Mukherjee, Chair Doug Boyer Colleen Robles An abstract of a dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Mathematics in the Graduate School of Duke University 2019 Copyright c 2019 by Shan Shan All rights reserved Abstract In this thesis, we propose probabilistic models on fibre bundles for learning the gen- erative process of data. The main tool we use is the diffusion kernel and we use it in two ways. First, we build from the diffusion kernel on a fibre bundle a projected kernel that generates robust representations of the data, and we test that it outperforms regular diffusion maps under noise. Second, this diffusion kernel gives rise to a nat- ural covariance function when defining Gaussian processes (GP) on the fibre bundle. To demonstrate the uses of GP on a fibre bundle, we apply it to simulated data on a M¨obiusstrip for the problem of prediction and regression. Parameter tuning can also be guided by a novel semi-group test arising from the geometric properties of dif- fusion kernel. For an example of real-world application, we use probabilistic models on fibre bundles to study evolutionary process on anatomical surfaces.

  • 2. Superoscillations.Pdf
    When the Whole Vibrates Faster than Any of its Parts Computational Superoscillation Theory Nicholas Wheeler December 2017 Introduction. The phenomenon/theory of “superoscillations”—brought to my attention by my friend Ahmed Sebbar1—originated in the time-symmetric formulation of quantum mechanics2 that gave rise to the theory of “weak measurements.” Recognition of the role that superoscillations play in that work was brought into explicit focus by Aharonov et al in 1990, and since that date the concept has found application to a remarkable variety of physical subject areas. Yakir Aharonov took his PhD in 1960 from the University of Bristol, where he worked with David Bohm.3 In 1992 a conference was convened at Bristol to celebrate Aharonov’s 60th birthday. It was on that occasion that the superoscillation phenomenon came first to the attention of Michael Berry (of the Bristol faculty), who in an essay “Faster than Fourier” contributed to the proceedings of that conference4 wrote that “He [Aharonov] told me that it is possible for functions to oscillate faster than any of their Fourier components. This seemed unbelievable, even paradoxical; I had heard nothing like it before. ” Berry was inspired to write a series of papers relating to the theory of superoscillation and its potential applications, as also by now have a great many other authors. 1 Private communication, 17 November 2017. 2 Y. Aharonov, P. G. Bergmann & J. L. Libowitz, “Time symmetry in the quantum meassurement process,” Phys. Rev. B 134, 1410–1416 (1964). 3 It was, I suspect, at the invitation of E. P Gross—who had collaborated with Bohm when both were at Princeton—that Aharonov spent 1960–1961 at Brandeis University, from which I had taken the first PhD and departed to Utrecht/CERN in February of 1960, so we never met.
