The three-dimensional structure of cadmium-substituted concanavalin A has been refined using X-PLOR. The R factor on all data between 8 and 2 A is 17.1%. The protein crystallizes in space group I222 with cell dimensions a = 88.7, b = 86.5 and c = 62.5 A and has one protein subunit per asymmetric unit. The final structure contains 237 amino acids, two Cd(More)
In contrast to the Android application layer, Android’s application framework’s internals and their influence on the platform security and user privacy are still largely a black box for us. In this paper, we establish a static runtime model of the application framework in order to study its internals and provide the first high-level classification of the(More)
With the introduction of Android 5 Lollipop, the Android Runtime (ART) superseded the Dalvik Virtual Machine (DVM) by introducing ahead-of-time compilation and native execution of applications, effectively deprecating seminal works such as TaintDroid that hitherto depend on the DVM. In this paper, we discuss alternatives to overcome those restrictions and(More)
Microgravity offers an environment for protein crystallization where there is an absence of convection and sedimentation. We have investigated the effect of microgravity conditions on the perfection of protein crystals. The quality of crystals for X-ray diffraction studies is characterized by a number of factors, namely size, mosaicity and the resolution(More)
The idea that familiar events can be encoded automatically has gained general acceptance in cognitive psychology since Posner and Boies (1971) first reported that reaction times to a secondary probe were not interfered with by letter encoding. More recently, Ogden, Martin, and Paap (1981) used a more valid control for estimating baseline probe performance(More)
In a letter-symbol classification task, flanking incompatible symbols slowed response latencies to letter targets, whereas incompatible letter flankers did not slow the classification of symbol targets. The conditions surrounding this asymmetry in response competition were investigated in five experiments. The results showed that: (1) the asymmetry was not(More)
