We examine the radius evolution of close-in giant planets with a planet evolution model that couples the orbital-tidal and thermal evolution. For 45 transiting systems, we compute a large grid of cooling/contraction paths forward in time, starting from a large phase space of initial semi-major axes and eccentricities. Given observational constraints at the current time for a given planet (semi-...

We investigate the orbital resonant history of Proteus and Larissa, the two largest inner Neptunian satellites discovered by Voyager 2. Due to tidal migration, these two satellites probably passed through their 2:1 mean-motion resonance a few hundred million years ago. We investigate this resonance passage as a method to excite orbital eccentricities and inclinations, and find interesting const...

It is suggested that a signi cant fraction of the low column-density absorption features seen in the spectra of quasars are produced in pressure-con ned tidal debris, that was built up in small groups and clusters of galaxies over a Hubble time. We show that the space-density and cross-section of tidal tails in groups of galaxies are large enough that they could constitute a major source of the...

Polar ring galaxies are peculiar systems in which a gas rich, nearly polar ring surrounds an early-type or elliptical host galaxy. Two formation scenarios for these objects have been proposed: they are thought to form either in major galaxy mergers or by tidal accretion of the polar material from a gas rich donor galaxy. Both scenarios are studied through N-body simulations including gas dynami...

Many CSPs can be effectively represented and efficiently solved using matrix models, in which the matrices may have symmetry between their rows and/or columns. Eliminating all such symmetry can be very costly as there are in general exponentially many symmetries. Cost-effective methods have been proposed to break much of the symmetry, if not all. In this paper, we continue with this line of res...

We review research on the ̄uency heuristic as a basis for the subjective experience of familiarity. Then, we explore the links between the construct of ̄uency and the automatic versus consciously controlled memory processes that are estimated using the process dissociation procedure, and the phenomenological experiences studied using ``Remember'' and ``Know'' judgements. Although the ̄uency tha...

background: the aim of this study was to prevent of increasing end tidal co2(et co 2) with changing of vital capacity and respiratory rate, when using of birthing filter in infants. materials and method: in a randomized clinical trial study, ninety four infant' patients were studied in three groups . basic values, such as: peak inspiratory pressure, tidal volume, minute ventilation, respiratory...

in recent years, several ocean tide models have been used to calculate tides using data of satellite and tide gauges data. global ocean tide models have many applications in various sciences such as geophysics, geology and geodesy and oceanography. considering­ the existence of many models, a quantitative evaluation of research, and ranking and selecting the best model of the global ocean tide ...

Estuary Ecosystem, the second largest estuary in North America and home to hundreds of species of ecological, commercial, and recreational value. Unlike other estuaries in the Mid-Atlantic, the Delaware estuary’s tide range is greater than the ocean tide range, generally about 2 meters. Beaches account for 52 percent of the bay’s shore, with marsh and eroding peat accounting for most of the rem...

We study the comparative statics of the incumbency advantage in a model of electoral selection and strategic challenger entry. The incumbency advantage arises in the model because, on average, incumbents have greater ability than challengers. This is true for two reasons: high-ability candidates are more likely to win election (electoral selection) and high-quality incumbents deter challengers ...
