Enhancing the significance of gravitational wave bursts through signal classification

The quest to observe gravitational waves challenges our ability to discriminate signals from detector noise. This issue is especially relevant for transient gravitational waves searches with a robust eyes wide open approach, the so called all- sky burst searches. Here we show how signal classification methods inspired by broad astrophysical characteristics can be implemented in all-sky burst searches preserving their generality. In our case study, we apply a multivariate analyses based on artificial neural networks to classify waves emitted in compact binary coalescences. We enhance by orders of magnitude the significance of signals belonging to this broad astrophysical class against the noise background. Alternatively, at a given level of mis-classification of noise events, we can detect about 1/4 more of the total signal population. We also show that a more general strategy of signal classification can actually be performed, by testing the ability of artificial neural networks in discriminating different signal classes. The possible impact on future observations by the LIGO-Virgo network of detectors is discussed by analysing recoloured noise from previous LIGO-Virgo data with coherent WaveBurst, one of the flagship pipelines dedicated to all-sky searches for transient gravitational waves

On the Consideration of Adoption and Implementation of The Next Generation Science Standards in a Local-Control Context: Supporting the Epistemology of Science through Education Policy

On the Consideration of Adoption and Implementation of The Next Generation Science Standards in a Local-Control Context: Supporting the Epistemology of Science through Education Policy Christopher C Lazzaro The primary purpose of this research is to understand how and why members at each of the three levels of the education system within a local-control state made the decisions they did in supporting or hindering the adoption and implementation of the Next Generation Science Standards. This research concentrates on three levels of the education system in a local-control state; 1) the state level 2) the district level, and 3) the school/teacher level, while investigating the following questions: 1. To what extent, and in what ways, do members in each of the three levels of the state education system advocate for adoption and implementation of the Next Generation Science Standards? 2. Are the members in each of the three levels motivated or compelled to consider adoption and implementation of the Next Generation Science Standards, why or why not? 3. To what extent, and in what ways, do the members in each of the three levels take into account science epistemology in their overall consideration of adoption/implementation of the NGSS? The data drew from a series of interviews from a prior study, "Challenges of Implementing the Next Generation Science Standards in Local-Control States in the U.S." (Sevian, Foster, and Scheff, 2012). After these data were coded and analyzed around the three research questions, this phenomenographic research study identified four key findings: Key Finding 1 - As the District Coordinators are uniquely situated within the state education system to be able to see both the on-the-ground practical implications and the high-level policy pressures of adopting and implementing the NGSS, they reflect the deepest level of awareness of how to best advocate for adoption and implementation of the NGSS. Key Finding 2 - Motivation to adopt and implement the NGSS is highly nuanced. The most significant factor influencing motivation to adopt or implement the NGSS at each level is related to assessment. The reasons assessment affects motivation is different at each level. Key Finding 3 - Each interviewee at each level demonstrated awareness that the NGSS are significantly different from prior standards in some way. While teachers and SSCs sometimes cited the science practices as the critical difference, they were not able to meaningfully elaborate on what "science practices" are. Conversely, the District Coordinators demonstrated a deeper level of awareness and were able to comment more specifically on the practices and how they would affect science education in their state. Key Finding 4 - Regardless of level, the better a participant reflected an awareness of epistemology, the more likely they were to advocate for adoption and implementation of the NGSS. Similarly, the better a participant reflected an awareness of epistemology, the more likely they were motivated to consider adoption and implementation of the NGSS. The implications of the findings in this current study can; inform the supplemental materials and dissemination of information by standards writers, help policy makers engage stakeholders appropriately at each level by illustrating how national reform efforts play out in local-control states, and aid school based employees by identifying how and where they can participate in state level policy discussion and where their input could be valuable

Giant Liquid Argon Observatory for Proton Decay, Neutrino Astrophysics and CP-violation in the Lepton Sector (GLACIER)

GLACIER (Giant Liquid Argon Charge Imaging ExpeRiment) is a large underground observatory for proton decay search, neutrino astrophysics and CP-violation studies in the lepton sector. Possible underground sites are studied within the FP7 LAGUNA project (Europe) and along the JPARC neutrino beam in collaboration with KEK (Japan). The concept is scalable to very large masses.Comment: 4 pages, 1 figure, Contribution to the Workshop "European Strategy for Future Neutrino Physics", CERN, Oct. 200
