Novel Way to Search for Light Dark Matter in Lepton Beam-Dump Experiments. [PDF]

open access: yesPhysical Review Letters, 2018
A novel mechanism to produce and detect light dark matter in experiments making use of GeV electrons (and positrons) impinging on a thick target (beam dump) is proposed.

Current Direct Neutrino Mass Experiments [PDF]

open access: yes, 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 (

Dark photon production through positron annihilation in beam-dump experiments [PDF]

open access: yesPhysical 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 ...

Resonant production of dark photons in positron beam dump experiments [PDF]

open access: yes, 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]

open access: yesIEEE 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]

open access: yesScience, 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 ...

Aurora B couples chromosome alignment with anaphase by targeting BubR1, Mad2, and Cenp-E to kinetochores

open access: yesJournal of Cell Biology, 2003
The Aurora/Ipl1 family of protein kinases plays multiple roles in mitosis and cytokinesis. Here, we describe ZM447439, a novel selective Aurora kinase inhibitor.

Billion-scale Commodity Embedding for E-commerce Recommendation in Alibaba [PDF]

open access: yesKnowledge 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

Inhibition of Eukaryotic Translation Elongation by Cycloheximide and Lactimidomycin

open access: yesNature Chemical Biology, 2010
Although the protein synthesis inhibitor cycloheximide (CHX) has been known for decades, its precise mechanism of action remains incompletely understood.
