Ohara 3_8

The possible involvement of Toll-like receptor (TLR) genome DNA in the prolongation and relapse of inflammatory intestinal diseases and alcoholic hepatic diseases has been reported. In this study, we examined the relationship of mutations of the TLR 2, 4, 6 and 9 genomic DNA to recurrent or intractable gastritis or gastric ulcers. The subjects were 32 patients, including 6 with H. pylori (Hp)po...

Security Review of the Light-Weight Access Point Protocol draft-ohara-capwap-lwapp-02

This document introduces the LWAPP protocol and provides an analysis of its security features. In particular, the public-key authentication, preshared-key authentication, and packet-level encryption are examined. Also, the security ramifications introduced by the IEEE 802.11 binding are reviewed. Lastly, recommendations on changes the the protocol are presented. Overall, LWAPP is “secure”. Howe...

Directly photoinscribed refractive index change and Bragg gratings in Ohara WMS-15 glass ceramic.

We inscribed thick volume gratings in WMS-15 glass ceramic by ultraviolet light at 193 and 248 nm. Unlike earlier work in ceramic materials, the inscription process modified the optical properties of the material without the need for any additional chemical or thermal processing. Experimental evidence from measurements of grating growth, thermal annealing, and spectral absorption indicates that...

Max L. Birnstiel (1933–2014)

Max L. Birnstiel When I first met Max in Zurich in the fall of 1974, ‘‘Switzerland’’ seemed to be written all over him. I had just arrived from the United States, and his reserved politeness, his aversion to jokes, and his habit of neither wasting nor mincing his words all fitted the cliché of the Swiss German. My impression was reinforced when he told me that his paternal ancestors had been gu...
