Time-triggered periodic control implementations are over provisioned for many execution scenarios in which the states of the controlled plants are close to equilibrium. To address this inefficient use of computation resources, researchers have proposed self-triggered control approaches in which the control task computes its execution deadline at runtime based on the state and dynamical properties
Incorporating the conceptual resources of the ontological argument for the existence of God into the underlying rationale of the cosmological ditto, I here present and defend a ‘cosmontological’ synthesis: an a posteriori argument for the existence of an all-perfect GOD: a being who, in virtue of being whatever it is better to be than not to be, is that than which a greater cannot be thought. Cent
Efficient fermentation of all the monomeric sugars derived from lignocellulose is crucial to increase the economy of bioethanol production, since they can account for a considerable fraction of the fermentable sugars in the raw material. This thesis describes the engineering of Saccharomyces cerevisiae strains for improved xylose, galactose and/or arabinose utilization. S. cerevisiae is the prefer
The western fertility decline is arguably the most significant demographic change to have occurred in the past 200 years, yet its causes and processes are still shrouded in ambiguity due to a lack of individual-level longitudinal data. A growing body of research has helped improve our understanding of the decline's causes by examining the development of socioeconomic differences in fertility using
Employing high-resolution spectra obtained with the near-UV-sensitive detector on the Keck I HIRES, supplemented by data obtained with the McDonald Observatory 2d-coudé, we have performed a comprehensive chemical composition analysis of the bright r-process-rich metal-poor red giant star HD 221170. Analysis of 57 individual neutral and ionized species yielded abundances for a total of 46 elements
Type 1 diabetes (T1D) is an autoimmune disease associated with the destruction of pancreatic β cells and genetically linked to human leukocyte antigen (HLA) class II DR3-DQ2 and DR4-DQ8 haplotypes. The +49A/G polymorphism of the immunoregulatory cytotoxic T-lymphocyte antigen 4 (CTLA-4) gene is also associated with T1D. Genetic and environmental risk factors precede the onset of T1D, which is char
Abstract in UndeterminedThe digital age has brought with it advantages and disadvantages. Few would deny the benefit of being able to store entire song collections on pocket-sized MP3 players. Fewer still would disregard the merits of grandparents in Sydney being able to have face-to-face conversations with grandchildren in Berlin.Certain problems however, have also developed. The music and film i
