Through the Basaltic Looking Glass : Paired Remote Sensing and Experimental Studies of Glass on Mars
Introduction: Glasses on Mars, formed by impact melting and volcanism, likely make up a significant fraction of the regolith because they accumulate over time and there have been few processes operating in the last ~3.5 Ga to destroy them [1]. These glasses have exciting astrobiological implications because they can host microbial colonies and preserve biosignatures [2-5]; they may have also se...
متن کاملStudies in Solution Sampling
We introduce novel algorithms for generating random solutions from a uniform distribution over the solutions of a boolean satisfiability problem. Our algorithms operate in two phases. In the first phase, we use a recently introduced SampleSearch scheme to generate biased samples while in the second phase we correct the bias by using either Sampling/Importance Resampling or the MetropolisHasting...
متن کاملStudies on Adsorption of Some Organic Dyes from Aqueous Solution onto Graphene Nanosheets
Graphene, a new member of the carbon family, was used as an adsorbent due to its exceptional capability to remove Rhodamine B (RB) and Malachite Green (MG), two organic dyes, from aqueous solutions. Adsorption kinetics of RB and MG onto graphene and adsorption capacity of the adsorbent were studied. Also the effects of parameters, including pH, contact time, temperature, and adsorbent dosag...
متن کاملProline zwitterion dynamics in solution, glass, and crystalline state.
Raman and Raman optical activity spectra of L- and D-proline zwitterionic (PROZW) forms were recorded for H(2)O and D(2)O solutions in a wide frequency range and analyzed with respect to the motion of the proline ring and rotation of the carbonyl group. The solution spectra were additionally compared to Raman scattering of glass and crystalline powder proline. Solution and glass spectral band b...
متن کاملRigorous Solution of a Mean Field Spin Glass Model
A separable spin glass model whose exchange integral takes the form Jij-J(ilj2+12jl) which was solved by van Hemmen et al. [12] using large deviation theory [14] is rigorously treated. The almost sure convergence criteria associated with the cumulant generating function C(t) with respect to the quenched random variables (is carefully investigated, and it is proved that the related excluded null...
