Spectroscopic SWIFT

INTRODUCTION Often the ability to obtain chemical-shift information is needed and advantageous in MRI. In addition to providing chemical information, the acquired spectral dimension can also be used to reduce image blur resulting from frequency shifts of all types. This work describes a new 3D and 4D spectroscopic technique involving an intrinsic frequency dimension. The method is based on an o...

Swift Regular Expression Matching

Queries involving Regular Expressions (RegEx) have a wide range of applications including document stores, bioinformatics and information retrieval. However, efficiently executing RegEx queries over large datasets remains a challenging task. Data scans do not scale well with input size; however, existing techniques that avoid data scans — referred to as “black-box” approaches — offer little or ...

Expression of Lewis(x), sialylated Lewis(x), Lewis(a), and sialylated Lewis(a) antigens in human lung carcinoma.

One hundred and five cases of various human lung neoplasms were studied immunohistochemically using monoclonal antibodies recognizing the antigens, Le(x), sialylated Le(x) (SLEX), Le(a), and sialylated Le(a) (SLEA). Of the 92 lung cancers examined for antigen expression SLEX was detected in 57% (52 cases), Le(x) in 42% (39), SLEA in 36% (33), and Le(a) in 23% (21). None of these antigens were e...
