HS-Domino resolves the trade-off between performance and noise margins in conventional CD-Domino logic while dissipating low dynamic power with minimal area overhead. A dual-threshold (MTCMOS) implementation of HS-Domino and DDCVS logic is also devised. This implementation achieves low leakage values during standby, while maintaining high performance and low dynamic power during the active mode.

DyCML circuits combine the advantages of MOS current mode logic (MCML) circuits with those of dynamic logic families to achieve high performance at a low-supply voltage with low-power dissipation. Unlike CML circuits, DyCML gates do not have a static current source, which makes DyCML a good candidate for portable devices and battery-powered systems. Simulation and test results show that DyCML circuits are superior to other logic styles in terms of power and delay. A 16-bit DyCML carry look-ahead adder (CLA), fabricated in 0.6-μm CMOS technology, attains a delay of 1.24 ns and dissipates 19.2 mW at 400 MHz

Several studies have found the assessment of the depth of stromal invasion by cancer of the cervix to be of prognostic value. These studies did not take into account patients whose diagnostic procedures required removal of much tumor (large loop excision of the transformation zone [LLETZ] and knife cone biopsies). Furthermore, the Royal College of Pathologists guidelines do not address this issue. Over the period of 6 years, 228 women had radical hysterectomy (RH) for stage Ib/IIa cervical cancer. The percentage of the depth of stromal invasion was measured according to the Royal College of Pathologist's guidelines in the UK. Patients who had large loop excision of the transformation zone and knife cone biopsies were excluded (91 patients). A Cox regression analysis showed that when nodal involvement, depth of stromal invasion, endothelial lined space invasion (ELSI), and tumor type were fitted simultaneously, only nodal involvement remained as a marker of adverse outcome. We recommend that when the DOI is measured, account should be taken of the LLETZ/knife cone biopsy size. A randomized controlled trial, which concludes that DOI is an independent prognostic factor, is needed. Until this is properly evaluated, we feel that including DOI as an essential part of the standard pathological report is not warranted.
