BIOCHEMISTRY Correction for “Confinement of caspase-12 proteolytic activity to autoprocessing,” by Sophie Roy, Jeffrey R. Sharom, Caroline Houde, Thomas P. Loisel, John P. Vaillancourt, Wei Shao, Maya Saleh, and Donald W. Nicholson, which appeared in issue 11, March 18, 2008, of Proc Natl Acad Sci USA (105:4133–4138; first published March 10, 2008; 10.1073/pnas.0706658105). The authors note tha...

Abettact SPLICE1 is a mixed-mode simulation program for large-scale integrated circuits. It performs concurrent electrical and logic simulation using event-driven selective-trace techniques. The electrical analysis uses a new algorithm , called Iterated Timing Analysis (ITA), which performs accurate electrical waveform analysis much faster than SPICEZ. The logic analysis features a new MOS-orie...

The first two implications are trivial. In [2], the second author showed that every almost α-continuous function is η-continuous. In [1], Dickman, Porter and Rubin proved that every η-continuous is θ-continuous and hence weakly continuous. Although θ-continuous functions behave, in general, nicely, they may cause some unexpected problems. For example, if f :X → Y is θ-continuous, then f :X → f(...

Indian Ocean literature has captured the porousness and fluidity that configure space through narrations in which history memory, both individual collective, blend to voice uninhabited silence forged by unsettled colonialism. M.G. Vassanji’s The Book of Secrets (1994) Abdulrazak Gurnah’s By Sea (2001) are perspicuous exponents undertows lurk behind troubled existence uprooted individuals for wh...

The study for this paper focuses on searching the optimal number of fingers to be used by a Selective-Rake receiver using different ultra wideband systems. The presence of multipath fading has been taken into account using a modified Saleh-Valenzuela model. Coherent and non-coherent detection has been performed within different combining approaches. Non-coherent techniques have been implemented...

The IEEE 802.15.3a standards body has developed a modification of the Saleh–Valenzuela (SV) multipath channel model as the accepted channel model for ultra-wideband (UWB) investigations. The SV model is a well-defined simulation model that is straightforward to implement. However, since the model as specified is not directly amenable to theoretical analysis, it is constructed here as a two-dime...

Saleh and Bonnet [Fechner Day 98, p. 344] have shown that, upon parafoveal stimulation and up to 6.5 c/deg, reaction time (RT) is a function of grating contrast multiplied by grating period. The present experiments extend these findings to foveal stimulation within a wider spatial-frequency (SF) range and to stimuli of different duration. Both RT and latency of visually evoked potentials (VEP) ...

This paper outlines a technique which can use multiple transmit antennas to send more than one binary bit using the same number of transmit antennas over a single transmission. It uses Ultra Wideband orthogonal pulse position modulation to achieve this, with the receiver employing a Rake receiver and a Maximum Ratio Combiner optimal detector. This is done over a Space Time Spreading Time Hoppin...
