The electron density reduced by ~2 orders of magnitude during high dust storm. The estimated electron density in the clear atmosphere of Mars is compared with measurements of Earth's ionosphere at nearly the same geophysical condition.doi:10.1002/2015JA021630...
Our results offer a view of surface properties complementary to Mars Orbiter Laser Altimeter (MOLA) pulse-width or baseline roughness maps and can be compared to SHARAD peak-echo properties to infer deviations from the average near-surface density. Latitudinal averaging of SHARAD-derived roughness ...
The laboratory analysis and the assessment of the results conclude that the bulk density at 10–20 cm is 5–10% higher compared to 0–10 cm for all land uses except woodlands (20%). In the 0–20 cm depth, croplands have 1.5 times higher bulk density (mean: 1.26 g cm...
The time period between 560 and 360 ka (MIS14 to MIS11) was critical for the evolution of the Neanderthal lineage and the appearance of Levallois technology in Europe. The shifts in the distribution of the human populations, driven by cyclical climate changes, are generally accepted to have pl...
acrylic-glass compared to glass, inhibiting thermal imaging. The thickness of the sand tank walls depends on the pressure exerted by the backfill material and the water in the pores (and on the material chosen). The resulting buckling pressure should be calculated before designing the sand tank...
In standing trees the highest values occurred in the first two years of the outbreak. Reproductive success was significantly related to colonisation density (negatively), tree diameter (positively), parasitoid density (negatively at high densities) and attack year (negatively). Colonisation density had...

aThe concept is also applicable to other planets and celestial bodies. For locations in the solar system with weaker gravity than Earth's (such as the Moon or Mars), the strength-to-density requirements are not as great for tether materials. Currently available materials (such as Kevlar) are...
A control of geological formations on fracturing process, has also been noted, with regard to the relative best fracturing obtained on the volcano-sedimentary rock, compared to intrusive rocks. This result is also consistent with those Youan Ta et al. (2008) and Lasm (2000). On the ...
An example of corrected data from two filtering methods compared to the observed data at 117 s after the onset is presented in Fig. 5. Fig. E.1 visualizes the results for some other selected time-stamps. Table 2 summarises the data range, standard deviation, and per cent of outliers ...
