Multilevel minimization in trust-region framework : algorithmic and software developments

Kopaničáková, Alena ; Krause, Rolf (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO021.

The field of scientific computing is associated with the modeling of complex physical phenomena. The resulting numerical models are often described by differential equations, which, in many cases, can be related to non-convex minimization problems. Thus, after discretization, the solution of large-scale non-convex optimization problem is required. Various iterative solution strategies can be...

Plasmodium falciparum antigens expressed on the surface of infected erythrocytes are important targets of naturally acquired immunity against malaria, but their high number and variability provide the pathogen with a powerful means of escape from host antibodies1,2,3,4. Although broadly reactive antibodies against these antigens could be useful as therapeutics and in vaccine design, their...

A clinal polymorphism in the insulin signaling transcription factor foxo contributes to life-history adaptation in Drosophila*

Durmaz, Esra ; Rajpurohit, Subhash ; Betancourt, Nicolas ; Fabian, Daniel K. ; Kapun, Martin ; Schmidt, Paul ; Flatt, Thomas

In: Evolution, 2019, vol. 73, no. 9, p. 1774–1792

A fundamental aim of adaptation genomics is to identify polymorphisms that underpin variation in fitness traits. In Drosophila melanogaster, latitudinal life‐history clines exist on multiple continents and make an excellent system for dissecting the genetics of adaptation. We have previously identified numerous clinal single‐nucleotide polymorphism in insulin/insulin‐like growth factor...
