PURPOSE The interleukin-23 receptor (IL-23R) has been shown to be associated with ankylosing spondylitis (AS) in many different populations. This study examined whether IL-23R polymorphisms were associated with susceptibility to this disease in a Chinese Han population. METHODS Three single-nucleotide polymorphisms (SNP), rs7517847, rs11209032, and rs17375018, were genotyped in 291 AS patient...

Cavity ring-down spectroscopy and pressure ramp measurements have been used to determine the extinction coefficients of CO2 in the deep-ultraviolet wavelength region, between 198 and 270 nm. The observed optical extin...

We have studied the photodissociation dynamics of expansion-cooled IO radicals at 454.9 nm, corresponding to the AP3/2–XP3/2 (1–0) bandhead, using velocity map ion imaging. The radicals were generated using a late-mixing ...

Backscattering from the rough water-bottom interface can serve as a surrogate probe source in time reversal. A time-gated portion of the reverberation then is refocused to the bottom interface at the corresponding range @Lingevitch et al., J. Acoust. Soc. Am. 111, 2609–2614 ~2002!#. In this paper, reverberation nulling is investigated to enhance active target detection without a priori knowledg...

We describe a low-power approach for heteronuclear cross-polarization (CP) at high magic-angle spinning (MAS) frequencies. It is based on second-order CP at the n = 0 Hartmann–Hahn condition. The mechanism for the polarizati...
