VoI. 123, No. 3 Ha-INDUCED B DIFFUSION IN MOS DEVICES 415 Furthermore, this model explains the inertness of Mo films with other glass components like SiO2, P205, and As203 which explains the observed diffusion-masking ability of Mo films against P. This study points out clearly for perhaps the first time the importance of the bulk crystallographic structure of a catalytic agent.

An attempt was made in the present study to express mouse tyrosinase cDNAs fused with the authentic genomic 5' non-coding flanking sequence in cultured albino melanocytes. One of the cDNA sequences, which expressed successfully and produced melanin pigments, was analyzed with respect to deduced amino acid sequence. Sequencing of the tyrosinase genomic gene revealed the existence of several sets of a characteristic structure which consists of a chain of two successive stem structures, CCAAT-homology and TATA box at its 5' non-coding region.It seems possible that this region represents the regulatory element of the tyrosinase gene. Unusually long GA cluster at 5' upstream region was also found.

Computational material discovery is under intense study owing to its ability to explore the vast space of chemical systems. Neural network potentials (NNPs) have been shown to be particularly effective in conducting atomistic simulations for such purposes. However, existing NNPs are generally designed for narrow target materials, making them unsuitable for broader applications in material discovery. Here we report a development of universal NNP called PreFerred Potential (PFP), which is able to handle any combination of 45 elements. Particular emphasis is placed on the datasets, which include a diverse set of virtual structures used to attain the universality. We demonstrated the applicability of PFP in selected domains: lithium diffusion in LiFeSO4F, molecular adsorption in metal-organic frameworks, an order–disorder transition of Cu-Au alloys, and material discovery for a Fischer–Tropsch catalyst. They showcase the power of PFP, and this technology provides a highly useful tool for material discovery.

A cDNA library was constructed from poly (A)+ mRNA from mouse melanocytes and screened using anti-tyrosinase antiserum and oligonucleotide probes corresponding to amino acid sequence of tyrosinase. Sequencing of some cDNA clones positive in these screenings gave a nucleotide sequence of 1838 nucleotides including a open reading frame of 1344 nucleotides.

The unique properties of fluorine substituents, leaving groups that also stabilize an α carbocation, are exploited in a high‐yielding synthesis of substituted [4]‐ to [6]helicenes in three or four steps from commercially available compounds: Two fused benzene rings are constructed in the title reaction of readily prepared 1,1‐difluoro‐1‐alkenes containing two aryl groups followed by dehydrogenation (see scheme).
