Managing the trade-off between groundwater resources and large-scale agriculture : the case of pistachio production in Iran

Akhavan, Ali ; Gonçalves, Paulo

In: System dynamics review, 2021, vol. 37, no. 2-3, p. 155-196

Benefiting from historically favorable conditions (e.g. low costs, fertile land, and abundant water), pistachio producers in Rafsanjan, Iran, have flourished, with pistachio orchards and production growing dramatically since the 1970s. Today, however, the enormous increase in water consumption associated with pistachio production has severely depleted groundwater aquifers, causing widespread...

Less is more : efficient hardware design through Approximate Logic Synthesis

Scarabottolo, Ilaria ; Pozzi, Laura (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO023.

As energy efficiency becomes a crucial concern in almost every kind of digital application, Approximate Computing gains popularity as a potential answer to this ever-growing energy quest. Approximate Computing is a design paradigm particularly suited for error- resilient applications, where small losses in accuracy do not represent a significant reduction in the quality of the result. In these...

Endocrine uncoupling of the trade-off between reproduction and somatic maintenance in eusocial insects

Rodrigues, Marisa A. ; Flatt, Thomas

In: Current Opinion in Insect Science, 2016, vol. 16, p. 1–8

In most animals reproduction trades off with somatic maintenance and survival. Physiologically this trade-off is mediated by hormones with opposite effects on reproduction and maintenance. In many insects, this regulation is achieved by an endocrine network that integrates insulin-like/IGF-1 signaling (IIS), juvenile hormone (JH), and the yolk precursor vitellogenin (Vg) (or, more generally,...

Horizons in the evolution of aging

Flatt, Thomas ; Partridge, Linda

In: BMC Biology, 2018, vol. 16, no. 1, p. 93

Between the 1930s and 50s, evolutionary biologists developed a successful theory of why organisms age, firmly rooted in population genetic principles. By the 1980s the evolution of aging had a secure experimental basis. Since the force of selection declines with age, aging evolves due to mutation accumulation or a benefit to fitness early in life. Here we review major insights and challenges...
