Cross sections for compound-nuclear reactions involving unstable targets are important for many applications, but can often not be measured directly. Several indirect methods have been proposed to determine neutron capture cross sections for unstable isotopes. We consider an approach that aims at constraining statistical calculations of capture cross sections with data obtained from light-ion transfer reactions such as (p, d). We discuss the theoretical descriptions that have to be developed in order to extract meaningful cross section constraints from such data and show some benchmark results.

An important ingredient for applications of nuclear physics to e.g. astrophysics or nuclear energy are the cross sections for reactions of neutrons with rare isotopes. Since direct measurements are often not possible, indirect methods like (d,p) reactions must be used instead. Those (d,p) reactions may be viewed as effective three-body reactions and described with Faddeev techniques. An additional challenge posed by (d,p) reactions involving heavier nuclei is the treatment of the Coulomb force. To avoid numerical complications in dealing with the screening of the Coulomb force, recently a new approach using the Coulomb distorted basis in momentum space was suggested. In order to implement this suggestion, one needs to derive a separable representation of neutron-and proton-nucleus optical potentials and compute their matrix elements in this basis.

From BPSS matrix theory considerations, it is expected that a single D(p+2)-brane action can be obtained from N D(p)-brane action in large N limit. We examine and confirm this expectation by working out the details of DBI and Chern-Simons terms of D(p+2)-brane action from D(p)-brane action. We show that the same relation works for non-BPS, as well as BPS branes.

The upsurge in the number of web users over the last two decades has resulted in a significant growth of online information. This information growth calls for recommenders that personalize the information proposed to each individual user. Nevertheless, personalization also opens major privacy concerns. This paper presents D2P, a novel protocol that ensures a strong form of differential privacy, which we call distance-based differential privacy, and which is particularly well suited to recommenders. D2P avoids revealing exact user profiles by creating altered profiles where each item is replaced with another one at some distance. We evaluate D2P analytically and experimentally on Movie Lens and Jester datasets and compare it with other private and non-private recommenders.

This document reports on the main topics discussed in the experimental overview talk on p(d) A results given at the Hot Quarks 2014 Workshop. Recent measurements of the production of high transverse momentum hadrons and jets, inclusive identified particles and their correlations, quarkonia and vector bosons are presented. They represent a small set of the currently available results, which provide a deeper understanding of the hot QCD matter produced in A A collisions and reveal the presence of unexpected phenomena in small systems.

To extend Iwasawa's classical theorem from Z(p)-towers to Z(p)(d)-towers, Greenberg conjectured that the exponent of p in the n-th class number in a Z(p)(d)-tower of a global field K ramified at finitely many primes is given by a polynomial in p(n) and n of total degree at most d for sufficiently large n. This conjecture remains open for d >=3D 2. In this paper, we prove that this conjecture is true in the function field case. Further, we propose a series of general conjectures on p-adic stability of zeta functions in a p-adic Lie tower of function fields. (C) 2018 Elsevier Inc. All rights reserved.
