Supported by a grant from the National Science Foundation (Grant No. CNS-0753686), NIC is currently in the fi rst stage of what is planned as a multi-phase project that aims to improve the image of computer science among high school students (with a special focus on gender and ethnic disparities) and encourage greater participation in computer science at the postsecondary level. Working with experienced marketing professionals, the NIC initiative seeks to: 1 understand the attitudes held by high school students toward the study of computing in college and potential computing careers; 2 create a set of market-tested messages that resonate with young people, accurately and positively represent the fi eld, and reshape the way computer science is portrayed to and perceived by young people; 3 conduct a pilot campaign using the tested messages. This pilot will assess strategies for how the messages can be used in a variety of ways to reach young people in their communities; 4 build a coalition of partners (computing organizations, universities, high school educators, and others) to adopt the messages and spread the word about the rewards and benefi ts of a career in computer science in honest, positive, and unifi ed ways; and 5 evaluate the results. -

Modulation Spaces, Wiener Amalgam Spaces, and Brownian Motions
MODULATION SPACES, WIENER AMALGAM SPACES, AND BROWNIAN MOTIONS ARP´ AD´ BENYI´ AND TADAHIRO OH Abstract. We study the local-in-time regularity of the Brownian motion with respect p;q p;q to localized variants of modulation spaces Ms and Wiener amalgam spaces Ws . We p;q p;q show that the periodic Brownian motion belongs locally in time to Ms (T) and Ws (T) for (s − 1)q < −1, and the condition on the indices is optimal. Moreover, with the p;q p;q Wiener measure µ on T, we show that (Ms (T); µ) and (Ws (T); µ) form abstract Wiener spaces for the same range of indices, yielding large deviation estimates. We also establish the endpoint regularity of the periodic Brownian motion with respect to a Besov-type s s space bp;1(T). Specifically, we prove that the Brownian motion belongs to bp;1(T) for (s − 1)p = −1, and it obeys a large deviation estimate. Finally, we revisit the regularity s of Brownian motion on usual local Besov spaces Bp;q, and indicate the endpoint large deviation estimates. Contents 1. Introduction 1 1.1.

Strong converse for the classical capacity of entanglement-breaking and Hadamard channels via a sandwiched R´enyi relative entropy Mark M. Wilde∗ Andreas Winter†‡ Dong Yang†§ May 23, 2014 Abstract A strong converse theorem for the classical capacity of a quantum channel states that the probability of correctly decoding a classical message converges exponentially fast to zero in the limit of many channel uses if the rate of communication exceeds the classical capacity of the channel. Along with a corresponding achievability statement for rates below the capacity, such a strong converse theorem enhances our understanding of the capacity as a very sharp dividing line between achievable and unachievable rates of communication. Here, we show that such a strong converse theorem holds for the classical capacity of all entanglement-breaking channels and all Hadamard channels (the complementary channels of the former). These results follow by bounding the success probability in terms of a “sandwiched” R´enyi relative entropy, by showing that this quantity is subadditive for all entanglement-breaking and Hadamard channels, and by relating this quantity to the Holevo capacity. Prior results regarding strong converse theorems for particular covariant channels emerge as a special case of our results. 1 Introduction One of the most fundamental tasks in quantum information theory is the transmission of classical data over many independent uses of a quantum channel, such that, for a fixed rate of communica- tion, the error probability of the transmission decreases to zero in the limit of many channel uses. The maximum rate at which this is possible for a given channel is known as the classical capacity of the channel. -

Weil. |||||||||||||||||||||- Classical Fourier Analysis pays a lot of attention to p d L (R ); k · kp because these spaces (specifically for p 2 f1; 2; 1g) are important to set up the Fourier transform as an integral transform which also respects convolution (we have the convolution theorem) and preserving the energy (meaning that it is 2 d a unitary transform of the Hilbert space L (R ); k · k2 ). |||||||||||||||||||||- d Occasionally the Schwartz space S(R ) is used and its dual 0 d S (R ), the space of tempered distributions (e.g. for PDE and d the kernel theorem, identifying operators from S(R ) to 0 d 0 2d S (R ) with their distributional kernels in S (R )).

Biographical Memoirs, VOLUME 82 PUBLISHED 2002 BY THE NATIONAL ACADEMY PRESS WASHINGTON, D.C. JACOB WOLFOWITZ March 19, 1910–July 16, 1981 BY SHELEMYAHU ZACKS ACOB WOLFOWITZ, A GIANT among the founders of modern Jstatistics, will always be remembered for his originality, deep thinking, clear mind, excellence in teaching, and vast contributions to statistical and information sciences. I met Wolfowitz for the first time in 1957, when he spent a sab- batical year at the Technion, Israel Institute of Technology. I was at the time a graduate student and a statistician at the building research station of the Technion. I had read papers of Wald and Wolfowitz before, and for me the meeting with Wolfowitz was a great opportunity to associate with a great scholar who was very kind to me and most helpful. I took his class at the Technion on statistical decision theory. Outside the classroom we used to spend time together over a cup of coffee or in his office discussing statistical problems. He gave me a lot of his time, as though I was his student. His advice on the correct approach to the theory of statistics accompanied my development as statistician for many years to come. Later we kept in touch, mostly by correspondence and in meetings of the Institute of Mathematical Statistics. I saw him the last time in his office at the University of Southern Florida in Tampa, where he spent the last years 3 4 BIOGRAPHICAL MEMOIRS of his life. -
Completeness of Shifted Dilates in Invariant Banach Spaces of Tempered Distributions
Completeness of shifted dilates in invariant Banach spaces of tempered distributions Hans G. Feichtinger∗ Anupam Gumber y August 17, 2020 Abstract We show that well-established methods from the theory of Banach modules and time-frequency analysis allow to derive completeness results for the collection of shifted and dilated version of a given (test) function in a quite general setting. While the basic ideas show strong similarity to the arguments used in a recent paper by V. Katsnelson we extend his results in several directions, both relaxing the assumptions and widening the range of applications. There is no need for the 2 Banach spaces considered to be embedded into L (R); k · k2 , nor is the Hilbert space structure relevant. We choose to present the results in the setting of the Euclidean spaces, because then the 0 d Schwartz space S (R )(d ≥ 1) of tempered distributions provides a well-established environment for mathematical analysis. We also establish connections to modulation spaces and Shubin classes d Qs(R ); k · kQs , showing that they are special cases of Katsnelson's setting (only) for s ≥ 0.

Short Cross-Disciplinary Cycles in Co-Authorship Graphs
How small is the center of science? Short cross-disciplinary cycles in co-authorship graphs Chris Fields 528 Zinnia Court Sonoma, CA 95476 USA fi[email protected] October 17, 2014 Abstract Cycles that cross two or more boundaries between disciplines in the co-authorship graph for all of science are used to set upper limits on the number of co-authored pa- pers required to cross 15 disciplines or subdisciplines ranging from macroeconomics to neurology. The upper limits obtained range from one (discrete mathematics, macroe- conomics and nuclear physics) to six (neuroscience). The 15 disciplines or subdis- ciplines examined form a “small world” with an average separation of only 2.0 co- authorship links. It is conjectured that the high-productivity, high average degree centers of all scientific disciplines form a small world, and therefore that the diameter of the co-authorship graph of all of science is only slightly larger than the average diameter of the co-authorship graphs of its subdisciplines. Keywords: Cross-displinary brokers; Field mobility; Graph centrality; Graph diameter; Nobel laureates; Preferential attachment; Small-world networks 1 Introduction Numerous studies have now confirmed the finding of Newman (2001, 2004) that the co- authorship graphs of many scientific disciplines can be characterized as “small worlds” comprising many dense clusters of researchers separated by relatively short (mean length 1 l ≤ 10) minimum paths (reviewed by Mali, Kronegger, Doreian and Ferligoj, 2012). Despite over two decades of efforts to make the world of science as a whole more interconnected by encouraging inter-, multi- or trans-disciplinary collaborations, however, the research enterprise remains organized into disciplines (Jacobs and Frickel, 2009). -
