Long-term variability of CO2 and O in the Mars upper atmosphere from MRO radio science data [PDF]

open access: yes, 2015
We estimate the annual variability of CO2 and O partial density using approximately 6years of Mars Reconnaissance Orbiter (MRO) radio science data from August 2006 to January 2012, which cover three full Martian years (from the northern hemisphere summer

Directed Transmission Method, A Fully Asynchronous approach to Solve Sparse Linear Systems in Parallel

open access: yes, 2008
In this paper, we propose a new distributed algorithm, called Directed Transmission Method (DTM). DTM is a fully asynchronous and continuous-time iterative algorithm to solve SPD sparse linear system.

Boosting the Nucleophilicity of the Diphenylphosphide Anion with Crown Ether Supported Heavy Alkali Metals to Facilitate Highly Efficient Catalytic Alkene Isomerisation

open access: yesAngewandte Chemie, EarlyView.
Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether‐supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One is descended with Cs(18‐crown‐6)PPh2 (1Cs) performing best.
