Predicting and characterizing the crystal structure of materials is a key problem in materials research and development. We report the results of ab initio LDA/GGA computations for the following systems: AgAu, AgCd, AgMg, AgMo∗, AgNa, AgNb∗, AgPd, AgRh∗, AgRu∗, AgTc∗, AgTi, AgY, AgZr, AlSc, AuCd, AuMo∗, AuNb, AuPd, AuPt∗, AuRh∗, AuRu∗, AuSc, AuTc∗, AuTi, AuY, AuZr, CdMo∗, CdNb∗, CdPd, CdPt, CdR...

Temperature modulated differential scanning calorimetry measurements on Agy(GexSe1−x )1−y glasses provide evidence for bimodal glass transition temperatures in Se-rich glasses (x < 1/3). At x = 0.20 and 0.25, thermal measurements performed as a function of Ag content in the 0 y 0.25 range reveal that the additive (Ag) segregates into an Ag2Se-rich glass phase, possessing a characteristic glass ...

Conventional tRNAs have highly conserved sequences, four-armed cloverleaf secondary structures, and L-shaped tertiary structures. However, metazoan mitochondrial tRNAs contain several exceptional structures. Almost all tRNAs(Ser) for AGY/N codons lack the D-arm. Furthermore, in some nematodes, no four-armed cloverleaf-type tRNAs are present: two tRNAs(Ser) without the D-arm and 20 tRNAs without...
