Stellar population studies show that low mass galaxies in all environments exhibit stellar halos that are older and more spherically distributed than the main body of the galaxy. In some cases, there is a significant intermediate age component that extends beyond the young disk. We examine a suite of Smoothed Particle Hydrodynamic (SPH) simulations and find that elevated early star formation ac...

The variational method with constraints recently developed by Verkley and Gerkema to describe maximumentropy atmospheric profiles is generalized to ideal gases but with temperature-dependent specific heats. In so doing, an extended and non standard potential temperature is introduced that is well suited for tackling the problem under consideration. This new formalism is successfully applied to ...

positive correlation at 65 +/5 degrees N geomagnetic latitude and altitudes 44-58 km in Figure 5. I am wondering about any possible significance of the large negative correlation, which is computed for 35 +/5 degrees S geomagnetic latitude and altitudes 50-62 km in Figure 5. Could the authors please elaborate on this as well? The mechanism for this is not yeat clear, but this is out of the scop...

To understand the properties and significance of highly radioactive particles in marine environment, we have examined seafloor sediment with a radioactivity ?1200 Bq/kg (dry weight; after decay correction to March 2011) collected 35 km northeast Fukushima Daiichi Nuclear Power Plant (FDNPP). Among 697 separated from sediment, two particles, D1-MAX D1-MID, had total Cs ?56 0.67 Bq (after 2011), ...

Environmental cues often trigger memories of past events (associative retrieval), and these memories are a form of prediction about imminent experience. Learning is driven by the detection of prediction violations, when the past and present diverge. Using intracranial electroencephalography (iEEG), we show that associative prediction violations elicit increased low-frequency power (in the slow-...

False memories are often demonstrated using the misinformation paradigm, in which a person's recollection of a witnessed event is altered after exposure to misinformation about the event. The neural basis of this phenomenon, however, remains unknown. We used fMRI to investigate encoding processes during the viewing of an event and misinformation to see whether neural activity during either enco...

The recent re-evaulation of the peculiar velocity field outside the Local Supercluster (Dekel et al. 1999) has permitted a re-examination of the origins of the peculiar velocity field within the Local Supercluster using the Mark III Catalog of Galaxy Peculiar Velocities. It is shown that the large-scale coherent pattern of peculiar velocities within the LSC are well-fit by a combination of the ...
