Since the invention of the mobile phone, a new generation of mobile communication standard has emerged every 10 years. Upgrading the technology of mobile networks in all areas takes few years. Hence, mobile phones should support the previous communication standards as well as the latest standards. Realizing a multi-standard mobile phone by multiple transceivers in parallel is neither a size-eff...

The integration of logic synthesis and physical design stages will become more important to meet the challenges of integrated circuit design as device densities continue to grow and feature sizes continue to shrink [1, 2]. Many contemporary designs use a combination of macro cells and standard cells to implement the desired system functions. In a typical design, there are usually many more stan...

The purposes of this 2-part study were to determine whether reduced distal femoral component geometry allows for routinely larger component sizes to be used and whether clinical or radiographic outcomes differ between total hip arthroplasty (THA) patients treated with either standard-length or short femoral components. Femoral component size and ongrowth surface area were retrospectively compar...

As a signing capability delegation technique, multi-proxy signature allows all signers in the delegated group to produce jointly a multi-proxy signature on the behalf of an original signer, and has been widely applied in distributed computing. Currently, most of multi-proxy signature schemes in the standard model cannot achieve strong unforgeablity, lightweight computation and short length of m...

We introduce a new class of non-standard variable-length codes, called adaptive codes. This class of codes associates a variable-length codeword to the symbol being encoded depending on the previous symbols in the input data string. An efficient algorithm for constructing adaptive codes of order one is presented. Then, we introduce a natural generalization of adaptive codes, called GA codes.

A number of problems have been reported with the use of standard length tracheostomy tubes in adult critical care patients. We measured the depth from the skin surface to the tracheal wall and the angle of the tracheal stoma during percutaneous tracheostomy. In vitro measurements were also performed on standard tracheostomy tubes. Comparison of in vivo and in vitro dimensions demonstrated that ...
