Systematic Structural Investigations on Phosphines

This work contributes to the systematic investigation of phosphines. In an attempt to deter­ mine the nature, shape, volume and direction of the lone pairs at the phosphorus atoms in phosphines, high resolution X-ray structure analyses of triphenylphosphine, tris(p-methoxyphenyl)phosphine, bis(2,4,6-triisopropylphenyl)phosphine, 1,1 -bis(diphenylphosphino)ethene and 4,5,6-triphenyl-4-phosphaspi...

Stuck on a channel

Stuck on a channel ctive Ca 2 channels, according to Hudmon et al. (page 537), get their own dedicated Ca 2 sensors that cause well-used channels to open with gusto. Some Ca 2 channels, including voltage-gated L-type channels, let through more Ca 2 per opening when they are used frequently. This positive feedback, known as facilitation, allows fast-beating cardiac cells, for instance, to beat h...

On Being Stuck in Time

It is sometimes claimed that non-human animals (and perhaps also young children) live their lives entirely in the present and are cognitively 'stuck in time'. Adult humans, by contrast, are said to be able to engage in 'mental time travel'. One possible way of making sense of this distinction is in terms of the idea that animals and young children cannot engage in tensed thought, which might se...

On coding for 'stuck-at' defects

Remark: In [5] new [120-41,50-31,241 codes are constructed for i = 0,1,2,3,4, as well as a [96,33,24] code. These codes may be obtained in the same way as the [99,35,24] code in Example 2. These codes were found independently and simultaneously by Ying Cheng [3]. are carefully defined and bounded. A reasonably practical convolutional coding scheme is described and simulated. Finally, some codes...

On Synthesizing and Identifying Stuck-Open Testable

We show that a class of CMOS circuits is a testable realization and static CMOS circuits synthesized by some existing synthesis systems belongs to this class. We propose a more “direct” solution to the problem of computing robust test-pairs for stuck-open faults by defining a new six-valued logic. This in turn gives us a solution to the problem of identifying stuck-open testable circuits.
