BACKGROUND Head and neck oncologic surgery is a time-consuming specialty that requires extensive resources and manpower. Case mix index (CMI) is used in evaluating the complexity and economic impact of surgeons. Head and neck oncologic surgeons generate significant revenue for hospitals, yet compensation is relatively low. METHODS Retrospective review of a tertiary hospital's case mix data fo...

The randomization scheme of hypervariable region takes crucial role in construction of a synthetic antibody library. The codon bias and inevitable 'stop' codon of conventional 'NNK' and 'NNS' codons limit their applications. Here we report a split-mix-split DNA synthesis method that can control over the amino acid composition and distribution of randomized sequences effectually. A fully synthet...

We define a new type of mix network that offers a reduced form of robustness: the mixnet can prove that every message it outputs corresponds to an input submitted by a player without revealing which input (for honest players). We call mixnets with this property reputable mixnets. Reputable mixnets are not fully robust, because they offer no guarantee that distinct outputs correspond to distinct...
