ABSTRACT Microlensing is proving to be one of the best techniques detect distant, low-mass planets around most common stars in Galaxy. In principle, Earth’s microlensing signal could offer chance for other technological civilizations find Earth across Galactic distances. We consider photometric potential and dub regions our Galaxy from which readily observable as ‘Earth zone’ (EMZ). The EMZ can...

The Torralba and Ambrona sites (Santonja et al., in: Santonja and Pérez-González, 2005 (eds.): 18-39) are 150 kilometres north east of Madrid on the watershed between the Ebro, Duero and Tagus Rivers, in the southern part of Soria Province. This is a strategic transit zone between the highlands of the Iberian Meseta (plateau) and the Jalón River Valley. An oblique perspective generated by a dig...

We report the first direct experimental observation of the ablative Richtmyer-Meshkov instability. It manifests itself in oscillations of areal mass that occur during the shock transit time, which are caused by the "rocket effect" or dynamic overpressure characteristic of interaction between the laser absorption zone and the ablation front. With the 4-ns-long Nike KrF laser pulse and our novel ...

The size and surface area of the mammalian brain are thought to be critical determinants of intellectual ability. Recent studies show that development of the gyrated human neocortex involves a lineage of neural stem and transit-amplifying cells that forms the outer subventricular zone (OSVZ), a proliferative region outside the ventricular epithelium. We discuss how proliferation of cells within...

In this paper we investigate the detectability of a habitable-zone exomoon around various configurations of exoplanetary systems with the Kepler Mission or photometry of approximately equal quality. We calculate both the predicted transit timing signal amplitudes and the estimated uncertainty on such measurements in order to calculate the confidence in detecting such bodies across a broad spect...

The distribution of Fucus serratus has a sharp boundary In northern S p a n F serratus dominates the m ~ d ~ n t e r t ~ d a l l e g ~ o n west of Novellana, Asturias but is absent further east In a short t r ans~ t~on zone F serratus 1s abundant within patches The causes underlying this pattern were investlgated by exper~rnental transplants of F serratus to locations In the transit~on zone and...

Recently there has been interest in the use of the laser slowed and trapped atoms for the development of high-accuracy atomic clocks.'` For slow-atom clocks, employing separated field excitation, the use of a Raman transition may have advantages over direct microwave excitation.4 6 This is because the two-zone Raman interaction has the demonstrated ability to reverse the sign of the ac Stark sh...

Urban rail transit systems are rapidly developing around the world. Due to a great deal of urban traffic pressure, improving the efficiency and capacity of urban rail transit systems is an increasing demand. Because it is a key subsystem of urban rail transit systems, communication-based train control(CBTC) is an automated train control system that makes use of train–ground wireless communicati...

Stem cells generate the differentiated progeny cells of adult tissues. Stem cells in the Caenorhabditis elegans hermaphrodite germline are maintained within a proliferative zone of ∼230 cells, ∼20 cell diameters in length, through GLP-1 Notch signaling. The distal tip cell caps the germline and supplies GLP-1-activating ligand, and the distal-most germ cells that occupy this niche are likely se...
