Generalised mathematical models for 3D magnetic reconnection at null points: magnetic reconnection at null points
… one candidate for such locations are magnetic null points, known to be abundant for example in the solar atmosphere. Reconnection leads to changes in the topology of the magnetic field, and energy being released as heat, kinetic energy and acceleration of particles. Thus reconnection is …

You Heard the New Theory?: A Syntactic Analysis of Null Subjects and Null Auxiliaries in English
The following investigation of null subjects and null auxiliaries in English has two principle goals. First, it seeks to describe the occurrence of null subjects and null auxiliaries in English sentences. Second, it proposes a set of rules which attempt to account for the appearance of sentences …

Gene expression profiling of myostatin null mice
… Previous work demonstrated that myostatin null mice (MKO) did respond to clenbuterol with increased body and muscle weights suggesting disparate mechanisms for each effect. We examined gene expression profiles of these mice to identify downstream targets of myostatin null- and …

Asynchronous Circuit Synthesis Using Multi-Threshold NULL Convention Logic
<p>As the demand for an energy-efficient alternative to traditional synchronous circuit design grows, hardware designers must reconsider the traditional clock tree. By doing away with the constrains of a clock, asynchronous sequential circuit designs can achieve a much greater level of efficiency. …
