Global energy perspectives to 2060 – WEC's World Energy Scenarios 2019

open access: yes, 2020
The recent signals in the energy sector indicate a major transformation taking shape in the energy sector in the decades to come. The potential trends are highlighted in three scenarios published by the World Energy Council in September 2019 and further ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Scenarios—using the complexity frame of reference to inform the construction of available futures in the possibility space

open access: yesFrontiers in Complex Systems
The global socio-ecological system in the era of the Capitalocene—the world system created by the use of fossil fuels to provide energy for the development of a growth-oriented capitalist logic in all areas of production and consumption—is facing a set ...

Critical thinking perspectives of undergraduate students

open access: yesAdvancements in Agricultural Development, 2020
Today’s learners need support in not only developing capacity for a global mindset, but also for thinking critically about the world. Employers are seeking graduates who can enter the workforce prepared to work within agriculture with the ability to ...

Mars base buildup scenarios [PDF]

open access: yes, 1985
Two Mars surface based build-up scenarios are presented in order to help visualize the mission and to serve as a basis for trade studies. In the first scenario, direct manned landings on the Martian surface occur early in the missions and scientific ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Scenario Modelling of University International Activities Based on Fuzzy Cognitive Maps

open access: yesProceedings of the International Conference on Applied Innovations in IT
In this article the concept of managing the effectiveness of international activities of universities based on fuzzy cognitive maps is discussed. The focus on the international relations currently plays an important role in almost all universities, as ...

Flow equations in generalized braneworld scenarios [PDF]

open access: yes, 2005
We discuss the flow equations in the context of general braneworld cosmologies with a modified Friedmann equation, for either an ordinary scalar field or a Dirac-Born-Infeld tachyon as inflaton candidates.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Perturbation amplitude in isocurvature inflation scenarios [PDF]

open access: yes, 1999
We make a detailed calculation of the amplitude of isocurvature perturbations arising from inflationary models in which the cold dark matter is represented by a scalar field which acquires perturbations during inflation.
