This Horizon Study describes a next-generation ground-based gravitational-wave observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Explorer will push astronomy towards edge observable universe ($z \sim 100$). The goals this are to describe and evaluate design concepts for Explorer; plan United States' leadership in astronomy; envisage role international effort build "Third-Generation" (3G) observatory network that make discoveries transformative across astronomy,...
Unmanned Aerial Vehicles (UAVs) equipped with air quality sensors offer a powerful solution for increasing the spatial and temporal resolution of data, searching detecting emission sources, monitoring emissions from fixed mobile sources. Despite numerous advantages using UAVs, their use, however, presents several challenges that limit broader adoption. For example, UAVs require efficient algorithms components to minimize power consumption, overall payload used on needs be small ensure...
We investigate the effects of observatory location on probability discovering optical/infrared (OIR) counterparts gravitational wave sources. show that, for LIGO–Virgo network, odds OIR some latitude dependence. A stronger effect is seen to arise from timing observing runs during year, with northern observatories having a better chance finding in winters. Assuming identical technical capabilities, tentative mid-2017 three-detector network run favors southern discovery electromagnetic counterparts.
Genetic studies indicate that more than 50% of women are genetically tetrachromatic, expressing four distinct types color photoreceptors (cone cells) in the retina. At least one functional tetrachromat has been identified laboratory tests. We hypothesize there is a large latent group population capable fundamentally richer experience, but we not yet aware this because lack tetrachromatic colors visual environment. This paper develops theory and engineering practice for fabricating...
Matrices are exceptionally useful in various fields of study as they provide a convenient framework to organize and manipulate data structured manner. However, modern matrices can involve billions elements, making their storage processing quite demanding terms computational resources memory usage. Although prohibitively large, such often approximately low rank. We propose an algorithm that exploits this structure obtain rank decomposition any matrix $\mathbf{A}$ $\mathbf{A} \approx...
Glottal Closure Instants (GCIs) correspond to the temporal locations of significant excitation vocal tract occurring during production voiced speech. GCI detection from speech signals is a well-studied problem given its importance in processing. Most existing approaches for adopt two-stage approach (i) Transformation signal into representative where GCIs are localized better, (ii) extraction using obtained first stage. The former stage accomplished processing techniques based on principles...
