Coherent Captain Mills: The Search for Sterile Neutrinos
The observation of neutrino oscillations confirms that the active neutrinos (νe, νΟ, νĎ) are comprised of three mass eigenstates with Îm2 values between 10-3 to 10-5 eV2 . However, a persistent phenomenon has been observed at LSND, MiniBooNE and other shortbaseline experiments (SBE) where Îm2 ~ 1eV2 and is not compatible with the current mixing between mass eigenstates. However, a 4th neutrino, a sterile neutrino (νs) that doesnât participate in weak interactions could explain the phenomena observed as SBEâs. An experiment has been constructed at TA-53 at Los Alamos National Laboratory to investigate this large Îm2 ~ 1eV2 and determine conclusively whether or not this large Îm2 is due to a ânewâ sterile neutrino.

Social media and protest mobilization: evidence from the Tunisian revolution
This article explores how social media acted as a catalyst for protest mobilization during the Tunisian revolution in late 2010 and early 2011. Using evidence from protests we argue that social media acted as an important resource for popular mobilization against the Ben Ali regime. Drawing on insights from âresource mobilization theoryâ, we show that social media (1) allowed a âdigital eliteâ to break the national media blackout through brokering information for mainstream media; (2) provided a basis for intergroup collaboration for a large âcycle of protestâ; (3) reported event magnitudes that raised the perception of success for potential free riders, and (4) provided additional âemotional mobilizationâ through depicting the worst atrocities associated with the regimeâs response to the protests. These findings are based on background talks with Tunisian bloggers and digital activists and a revealed preference survey conducted among a sample of Tunisian internet users (FebruaryâMay 2012)
Report of the CCFA Pediatric Bone, Growth and Muscle Health Workshop, New York City, November 11-12, 2011, With Updates
Growth retardation, delayed puberty, decreased bone mass, altered bone architecture, hypovitaminosis D and skeletal muscle mass deficits are common in children with inflammatory bowel diseases. The Crohn's and Colitis Foundation of America sponsored a multidisciplinary workshop on the subject of Bone and Skeletal Growth in Pediatric IBD, held in New York City in November 2011. The topic of the workshop was a key recommendation of the Foundation's Pediatric Challenges meeting in 2005. The Litwin Foundation provided a generous grant to support this crucial research and workshop through the CCFA. The workshop featured 15 presentations by researchers from the United States, Canada, Switzerland, Germany, and the United Kingdom and a number of posters elucidating diverse aspects of the problem of growth retardation and compromised bone health in pediatric Crohn's disease and ulcerative colitis. The workshop comprised original, basic, and clinical research and relevant reviews of underlying genetics, molecular biology, endocrinology, immunology, and bone physiology research. Investigators funded by CCFA and the Litwin Family Foundation are marked by an asterisk after their name in the text. Workshop presentations fell under 3 broad categories: Mechanisms of Suppression and Growth of Bone Cell Function by Inflammation, Impact of IBD on Growth and Bone Health, and Approaches to Address Growth Failure and Low Bone Mass in Children with IBD, summarized herein. We have cited the publications that resulted from this granting mechanism in the appropriate section and references for pertinent updates on each topic
