Dark photon production through positron annihilation in beam-dump experiments [PDF]
Physical Review D, 2018 High energy positron annihilation is a viable mechanism to produce dark photons ($A^\prime$). This reaction plays a significant role in beam-dump experiments using experiments using multi-GeV electron-beams on thick targets by enhancing the sensitivity ...

Current Direct Neutrino Mass Experiments [PDF]
, 2013 In this contribution, we review the status and perspectives of direct neutrino mass experiments, which investigate the kinematics of -decays of specific isotopes (3H, 187Re, 163Ho) to derive model-independent information on the averaged electron (

Resonant production of dark photons in positron beam dump experiments [PDF]
, 2018 Positrons beam dump experiments have unique features to search for very narrow resonances coupled superweakly to ${e}^{+}{e}^{\ensuremath{-}}$ pairs. Due to the continued loss of energy from soft photon bremsstrahlung, in the first few radiation lengths ...

Decoding by linear programming [PDF]
IEEE Transactions on Information Theory, 2005 This paper considers a natural error correcting problem with real valued input/output. We wish to recover an input vector f/spl isin/R/sup n/ from corrupted measurements y=Af+e.

Fine Structure Constant Defines Visual Transparency of Graphene [PDF]
Science, 2008 There are few phenomena in condensed matter physics that are defined only by the fundamental constants and do not depend on material parameters. Examples are the resistivity quantum, h/e2 (h is Planck's constant and e the electron charge), that appears ...

Quantifying E. coli proteome and transcriptome with single-molecule sensitivity in single cells
Science, 2010 Devil in the Detail Genetically identical cells in the same environment can show variation in gene expression that may cause phenotypic variation at the single-cell level. But how noisy are most genes? Taniguchi et al. (p.

Billion-scale Commodity Embedding for E-commerce Recommendation in Alibaba [PDF]
Knowledge Discovery and Data Mining, 2018 Recommender systems (RSs) have been the most important technology for increasing the business in Taobao, the largest online consumer-to-consumer (C2C) platform in China. There are three major challenges facing RS in Taobao: scalability, sparsity and cold
