We report the two-dimensional alignment of semiconductor islands using rudimentary metal patterning to control nucleation and growth. In the Ge on Si system, a square array of submicron Au dots on the Si (001) surface induces the assembly of deposited Ge adatoms into an extensive island lattice. Remarkably, these highly ordered Ge islands form between the patterned Au dots and are characterized...

We analyze the effects that the Ge profile shape has upon the bias and temperature characteristics of SiGe HBT's. The widely used bandgap reference (BGR) design equation and a more general analytical expression we developed incorporating Ge grading are used to compare silicon devices to their SiGe counterparts. Measurement and simulation show that although the Ge-ramp effect is negligible in th...


 La hepatitis C aguda es asintomática o inespecífica en un 80 % de los casos, por lo que su diagnóstico suele pasar inadvertido, con escasas descripciones evolución y manejo la literatura. El clearance es- pontáneo se produce sólo el 20 %, ocurriendo general, dentro las 12 semanas desde infección. Las guías clínicas recomiendan mínimo seguimiento 12-16 antes considerar tratamiento antivir...

The paper is a continuation of [Gi]. Extending the methods of [Gi] we show the following: Let κ = ⋃ n<ω κn, κ0 < κ1 < · · · < κn < · · · (1) if each κn carries an extender of the length of the first Mahlo above κn, then for every λ > κ there is a generic extension satisfying 2 ≥ λ; (2) if each κn carries an extender of the length of the first fixed point of the א-function above κn of order n, t...

Background: This study was carried out to assess the effects of MnTBAP, a cell permeable antioxidant, on motility, membrane integrity, capacitation status and in vitro fertilization ability of frozen-thawed ram semen. Materials and Methods: Fresh semen ejaculates were collected with artificial vagina from five rams, mixed and divided into five equal fractions, and diluted (1:20 v/v) with commer...

We review the construction of the extender algebra, a Boolean algebra which is due to Woodin, with δ-many generators. The resulting genericity iteration is applied to prove a new Σ1-absoluteness theorem for c.c.c. forcings with ordinal parameters. Additionally we introduce and discuss sets that extend to a class with unique condensation. We analyse the sets that extend to classes with unique co...

the ammi and sreg gge   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (gei) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. the objective of this study was to assess the effect of gei on grain yield of barely advanced lines and exploit the positive gei effect us...
