Molecular biology of celluloytic fungi
Since publication of the first edition of Volume II in 1995, several developments in fungal molecular biology - such as fungal genome projects - have progressed tremendously. This in turn has affected fundamental genetics as well as biotechnology. To accommodate these developments, the second edition has been completely updated and all chapters have been revised. In addition, the volume contains five new chapters dealing with different aspects of fungal molecular genetics. Topics include: Nuclear and extranuclear genetics; functional genomics; biotechnical genetics; yeasts and filamentous fungi.22 page(s
Measurement of the 3He mass diffusion coefficient in superfluid 4He over the 0.45 0.95 K temperature range
The neutron electric dipole moment experiment at the Spallation Neutron Source
Novel experimental techniques are required to make the next big leap in neutron electric dipole moment experimental sensitivity, both in terms of statistics and systematic error control. The nEDM experiment at the Spallation Neutron Source (nEDM@SNS) will implement the scheme of Golub & Lamoreaux [Phys. Rep., 237, 1 (1994)]. The unique properties of combining polarized ultracold neutrons, polarized 3He, and superfluid 4He will be exploited to provide a sensitivity to ⌠10â28âeâ·âcm. Our cryogenic apparatus will deploy two small (3âL) measurement cells with a high density of ultracold neutrons produced and spin analyzed in situ. The electric field strength, precession time, magnetic shielding, and detected UCN number will all be enhanced compared to previous room temperature Ramsey measurements. Our 3He co-magnetometer offers unique control of systematic effects, in particular the Bloch-Siegert induced false EDM. Furthermore, there will be two distinct measurement modes: free precession and dressed spin. This will provide an important self-check of our results. Following five years of âcritical component demonstration,â our collaboration transitioned to a âlarge scale integrationâ phase in 2018. An overview of our measurement techniques, experimental design, and brief updates are described in these proceedings
