Thermal boundary resistance from transient nanocalorimetry: a multiscale modeling approach

The Thermal Boundary Resistance at the interface between a nanosized Al film and an Al_{2}O_{3} substrate is investigated at an atomistic level. A room temperature value of 1.4 m^{2}K/GW is found. The thermal dynamics occurring in time-resolved thermo-reflectance experiments is then modelled via macro-physics equations upon insertion of the materials parameters obtained from atomistic simulations. Electrons and phonons non-equilibrium and spatio-temporal temperatures inhomo- geneities are found to persist up to the nanosecond time scale. These results question the validity of the commonly adopted lumped thermal capacitance model in interpreting transient nanocalorimetry experiments. The strategy adopted in the literature to extract the Thermal Boundary Resistance from transient reflectivity traces is revised at the light of the present findings. The results are of relevance beyond the specific system, the physical picture being general and readily extendable to other heterojunctions.Comment: 12 pages, 8 figure

Antimycobacterial activity of new 3,5-disubstituted 1,3,4-oxadiazol-2(3H)-one derivatives. Molecular modeling investigations

1-(3,5-Diaryl-4,5-dihydro-1H-pyrazol-4-yl)-1H-imidazole derivatives were synthesized and tested for their in vitro antifungal and antimycobacterial activities. These imidazole derivatives showed an excellent antifungal activity against a clinical strain of Candida albicans and an interesting antitubercular activity against Mycobacterium tuberculosis H37Rv reference strain

The gene for autosomal dominant spinocerebellar ataxia (SCA1) maps centromeric to D6S89 and shows no recombination, in nine large kindreds, with a dinucleotide repeat at the AM10 locus

Spinocerebellar ataxia type 1 (SCA1) is an autosomal dominant disorder which is genetically linked to the short arm of chromosome 6, telomeric to the human major histocompatibility complex (HLA) and very close to D6S89. Previous multipoint linkage analysis using HLA, D6S89, and SCA1 suggested that SCA1 maps centromeric to D6S89. Data from this study using nine large kindreds indicate a maximum lod score between SCA1 and D6S89 of 67.58 at a maximum recombination fraction of .004. To localize SCA1 more precisely, we identified five dinucleotide polymorphisms near D6S89. Genotypic analyses at these polymorphic loci were carried out in nine multigeneration SCA1 kindreds and in the Centre d'Etude du Polymorphisme Humain reference families. A new marker, AM10GA, demonstrates no recombination with SCA1. The maximum lod score for AM10GA linkage to SCA1 is 42.14 at a recombination fraction of 0. Linkage analysis and analysis of recombination events confirm that SCA1 maps centromeric to D6S89 and establish the following order: CEN-D6S109-AM10GA/SCA1-D6S89-LR40-D6S20 2-TEL
