Vibronic and vibrational spectra of 2-(2-fluoro-phenyl)-ethylamine (2-FPEA) conformers were measured in a molecular beam by resonant two-photon ionization (R2PI), ultraviolet-ultraviolet hole burning (UV-UV HB) spectroscopy, and ionization-loss stimulated Raman spectroscopy (ILSRS). The measured ILSR spectral signatures in the survey spectra of the amino group region and in the broad spectral r...

The murine 17th chromosome contains two regions of particular interest to biologists , the Tit complex and the major histocompatibility complex (MHC). 1 The T/t complex controls a number of loci that have important functions in embryonic development (1); the MHC encodes gene products that are involved in cellular interactions critical for immune function (2). A third region, Tla, located telome...

The paper advances three main theses, drawn from a study of the Australian and US economies as far back as 1870. The fi rst is that two of the popular channels for explaining the degree of co-movement between economies, trade and structural similarity, would seem to be of little help in accounting for the extent of correlation between Australia and the US, or how this has changed over time. On ...

Using eigenvalue analysis, it was shown by Erdös et al. that with the exception of C4, there are no graphs of diameter 2, maximum degree d and d vertices. In this paper, we prove a number of structural properties of regular graphs of diameter 2, maximum degree d and order d − 1.

moderate to excellent entantio- and stereoselectivities (ee’s 54-100%) were observed in ple catalyzed hydrolysis of (±)-ethyl 5-oxo-endo-tricyclo[5.2.1.02,6] deca-8-ene-2-carboxylate 5 and the structurally related open chain bicyclic structures (±)-ethyl 3-acetylbicyclo[2.2.1]hept-5-ene-2-carboxylates 7, 9 and (±)-ethyl 3-propanoylbicyclo[2.2.1]hept-5-ene-2-carboxylates 8, 10. a pronounced pref...

Since the introduction of covariance-based structural equation modeling (SEM) by Jöreskog in 1973, this technique has been received with considerable interest among empirical researchers. However, the predominance of LISREL, certainly the most well-known tool to perform this kind of analysis, has led to the fact that not all researchers are aware of alternative techniques for SEM, such as parti...

Gene3D http://gene3d.biochem.ucl.ac.uk is a database of domain annotations of Ensembl and UniProtKB protein sequences. Domains are predicted using a library of profile HMMs representing 2737 CATH superfamilies. Gene3D has previously featured in the Database issue of NAR and here we report updates to the website and database. The current Gene3D (v14) release has expanded its domain assignments t...
