We propose a formal representation of imperatives in computational systems, and a multi-agent dialogue protocol to argue over these.

The critical questions enable the identification of att...

During plant epidermal development, many cell types are generated fromprotodermal cells, a process requiringcomplex co-ordinationof cell division, growth, endoreduplication and the acquisition of differentiated cellular morphologies. Herewe show that theArabidopsis phytocalpain DEFECTIVE KERNEL 1 (DEK1) promotes the differentiated epidermal state. Plants with reduced DEK1 activity produce cotyl...

Photoelectrochemical water splitting is a promising route for the renewable production of hydrogen fuel. This work presents the results of a technical and economic feasibility analysis conducted for four hypothetical, centralized, large-scale hydrogen production plants based on this technology. The four reactor types considered were a single bed particle suspension system, a dual bed particle s...

New neurons are generated throughout life in distinct regions of the mammalian brain. This process, called adult neurogenesis, has been implicated in physiological brain function, and failing or altered neurogenesis has been associated with a number of neuropsychiatric diseases. Here, we provide an overview of themechanisms governing the neurogenic process in the adult brain and describe how ne...
