Power spectrum analysis of staggered quadriphase-shift-keyed signals

Mathematical analysis of power spectrum of outputs from high-reliability communication system is used to determine system bandwidth. Analysis provides mathematical relationships of signal power spectrum at output of hard limiter for any type of baseband pulse input subjected only to output parameter constraints

Study of symmetry in F(R) theory of gravity

An action in which the Ricci scalar is nonminimally coupled with a scalar field and contains higher order curvature invariant terms carries a conserved current under certain conditions that decouples geometric part from the scalar field. The conserved current relates the pair of arbitrary coupling parameters $f(\phi)$ and $\omega(\phi)$ with the gravitational field variable, where $\omega(\phi)$ is the Brans-Dicke coupling parameter. The existence of such conserved current may be helpful to sketch the cosmological evolution from its early age till date in a single frame.Comment: 6 page

Revision of Earth-sized Kepler Planet Candidate Properties with High Resolution Imaging by Hubble Space Telescope

We present the results of our Hubble Space Telescope program and describe how our analysis methods were used to re-evaluate the habitability of some of the most interesting Kepler planet candidates. Our program observed 22 Kepler Object of Interest (KOI) host stars, several of which were found to be multiple star systems unresolved by Kepler. We use our high-resolution imaging to spatially resolve the stellar multiplicity of Kepler-296, KOI-2626, and KOI-3049, and develop a conversion to the Kepler photometry (Kp) from the F555W and F775W filters on WFC3/UVIS. The binary system Kepler-296 (5 planets) has a projected separation of 0.217" (80AU); KOI-2626 (1 planet candidate) is a triple star system with a projected separation of 0.201" (70AU) between the primary and secondary components and 0.161" (55AU) between the primary and tertiary; and the binary system KOI-3049 (1 planet candidate) has a projected separation of 0.464" (225AU). We use our measured photometry to fit the separated stellar components to the latest Victoria-Regina Stellar Models with synthetic photometry to conclude that the systems are coeval. The components of the three systems range from mid-K dwarf to mid-M dwarf spectral types. We solved for the planetary properties of each system analytically and via an MCMC algorithm using our independent stellar parameters. The planets range from ~1.6R_Earth to ~4.2R_Earth, mostly Super Earths and mini-Neptunes. As a result of the stellar multiplicity, some planets previously in the Habitable Zone are, in fact, not, and other planets may be habitable depending on their assumed stellar host.Comment: 16 pages, 10 figures, ApJ, 804, 9

Hubble Space Telescope High Resolution Imaging of Kepler Small and Cool Exoplanet Host Stars

High resolution imaging is an important tool for follow-up study of exoplanet candidates found via transit detection with the Kepler Mission. We discuss here HST imaging with the WFC3 of 23 stars that host particularly interesting Kepler planet candidates based on their small size and cool equilibrium temperature estimates. Results include detections, exclusion of background stars that could be a source of false positives for the transits, and detection of physically-associated companions in a number of cases providing dilution measures necessary for planet parameter refinement. For six KOIs, we find that there is ambiguity in which star hosts the transiting planet(s), with potentially strong implications for planetary characteristics. Our sample is evenly distributed in G, K, and M spectral types. Albeit with a small sample size, we find that physically-associated binaries are more common than expected at each spectral type, reaching a factor of 10 frequency excess at M. We document the program detection sensitivities, detections, and deliverables to the Kepler follow-up program archive.Comment: Accepted for the Astronomical Journal; 13 pages with 9 figure

L’autorégulation de l’apprentissage par la lecture d’adolescents en milieu défavorisé

Cette étude a pour but de présenter les portraits d’autorégulation, lors de l’apprentissage par la lecture, de 20 545 élèves du secondaire (12 à 17 ans) fréquentant 59 écoles francophones de milieux défavorisés du Québec. Elle repose sur le questionnaire d’évaluation Lire pour apprendre (Cartier et Butler, 2003). Les résultats montrent que les élèves voient une certaine complexité à la situation, par leur interprétation, leurs objectifs et les critères de performance. Le volet apprentissage de la situation est moins ciblé. Par ailleurs, les élèves présentent des portraits d’autorégulation lacunaires. Des différences d’autorégulation entre les élèves du début et de la fin du secondaire ont été observées.This study presents a portrait of the self-regulated learning-by-reading strategies of 20,545 secondary level students (aged 12 to 17) from 59 Francophone schools in low socio-economic areas in Quebec. The authors applied an evaluation questionnaire, “Lire pour apprendre” (Cartier et Butler, 2003). Results show that students understand the complexity of a situation based on their interpretation, their objectives and their performance criteria. The learning aspect in the situation is less targeted. However, students present self-regulated learning strategies that are inadequate. Differences in self-regulation by students at the beginning and at the end of the secondary level were found.Este estudio tiene por objetivo presentar los perfiles de autorregulación durante el aprendizaje por la lectura de 20 545 alumnos de la secundaria (de 12 a 17 años de edad) provenientes de 59 escuelas francófonas de medios desfavorecidos de la provincia de Quebec. Se fundamenta en el cuestionario de evaluación Lire pour apprendre (Cartier y Butler, 2003). Los resultados muestran que los alumnos encuentran una cierta complejidad a la situación por su interpretación, sus objetivos y los criterios de desempeño. La parte « aprendizaje » de la situación se encuentra menos señalada. Por otro lado, los alumnos presentan perfiles de autorregulación con lagunas. Se observaron diferencias de autorregulación entre los alumnos del principio y del final de la secundaria
