A review of volatiles in the Martian interior [PDF]

open access: yes, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Skinning maps [PDF]

open access: yes, 2009
Let M be a hyperbolic 3-manifold with nonempty totally geodesic boundary. We prove that there are upper and lower bounds on the diameter of the skinning map of M that depend only on the volume of the hyperbolic structure with totally geodesic boundary ...

Change of the plane of oscillation of a Foucault pendulum from simple pictures

open access: yes, 2010
The change of the plane of oscillation of a Foucault pendulum is calculated without using equations of motion, the Gauss-Bonnet theorem, parallel transport, or assumptions that are difficult to explain.Comment: 5 pages, 4 ...

Effect of dietary supplementation with full-fat silkworm (Bombyx mori L.) chrysalis meal on growth performance and meat quality of Rhode Island Red × Fayoumi crossbred chickens

open access: yesItalian Journal of Animal Science, 2020
The objective was to study the effect of the partial substitution of soybean meal and oil with full-fat silkworm (Bombyx mori L.) meal (SWM) in the diet of growing chickens, on their growth and meat quality traits. A total of 195 1-day-old chicks of both

Approximation of maps into spheres by regulous maps [PDF]

open access: yes, 2017
Let $X$ be a compact real algebraic set of dimension $n$. We prove that every Euclidean continuous map from $X$ into the unit $n$-sphere can be approximated by regulous map.

Phylodynamic and phylogeographic reconstruction of IBV lineages: diverse paths and determinants, one goal for control

open access: yesScientific Reports
Infectious bronchitis virus (IBV) is a genetically diverse avian coronavirus that significantly impacts global poultry production. While IBV evolution and spread have been widely studied, most analyses lack global scope and statistical evaluation of ...
