We report measurements of the de Haas–van Alphen ~DHVA! effect and ac susceptibility in the layered organic superconductor k-(BEDT-TTF)2Cu(NCS)2.The amplitude of the DHVA oscillations is attenuated over a wide field range above the irreversibility line, B irr(B), below which a rigid flux lattice is formed. Thus the DHVA effect provides a unique probe of the superconducting fluctuations at high ...

We have recently shown that a monoclonal antibody, designated M131, that binds a surface phosphorylcholine epitope on Treponema pallidum possesses complement-dependent killing activity and confers partial protection in rabbits following passive immunization (Blanco et al., 2005, Infect. Immun. 73:3083-3095). In this study, the protective potential of M131 was further tested using the rabbit ski...

In this note, we report the first Minnesota state records of Osmia (Helicosmia) georgica Cresson 1878,Megachile (Sayapis) inimica 1872, and Megachile frugalis which were collected in 2018. We also provide description nest structure M. frugalis. All three species typically have more southern distributions. The shows similar to other subgenus Sayapis Titus, such as pugnata, particularly that long...
