Doing More With Less: Cutting Food Loss and Waste in the EU and Its Impact on Food Security
Sustainable Development, EarlyView.ABSTRACT In September 2025, the European Parliament and Council signed the law of the Revision of the EU waste framework directive, which includes also reductions for food loss and waste (FLW). This comes at a time of concern over the EU's strategic autonomy for its agrifood sector.

Theory of the Spatio-Temporal Dynamics of Transport Bifurcations
, 1996 The development and time evolution of a transport barrier in a magnetically confined plasma with non-monotonic, nonlinear dependence of the anomalous flux on mean gradients is analyzed.

Plasma and Fusion Research, 2008 In helical systems, neoclassical transport is one of the important issues in addition to anomalous transport, because of a strong temperature dependency of heat conductivity and an important role in the radial electric field determination. Therefore, the development of a reliable tool for the neoclassical transport analysis is necessary for the ...

Sustainable Development, EarlyView.ABSTRACT Identifying the factors that influence sustainable purchasing behavior is an important step in understanding the phenomenon and informing industry efforts to promote sustainable consumption. This study aims to develop a situation‐ and context‐specific model that explains sustainable purchasing behavior by drawing on three distinct theoretical ...

Direct optimization of neoclassical ion transport in stellarator reactors
Nuclear FusionWe directly optimize stellarator neoclassical ion transport while holding neoclassical electron transport at a moderate level, creating a scenario favorable for impurity expulsion and retaining good ion confinement.

Sustainable Development, EarlyView.ABSTRACT Championed as a pathway for sustainable growth, the “blue economy” (BE) has garnered increasing interest in recent decades. International organizations like the World Bank and the Organization for Economic Cooperation and Development (OECD) increasingly point to marine resources and activities as a “new frontier” for economic growth ...

Critical gradient turbulence optimization toward a compact stellarator reactor concept
Physical Review Research, 2023 Integrating turbulence into stellarator optimization is achieved by targeting the onset for the ion-temperature-gradient mode, highlighting effects of field line curvature, parallel connection length, local magnetic shear, and flux surface expansion. The

Neoclassical transport in a elliptic tokamak [PDF]
The Physics of Fluids, 1977 Neoclassical transport for an elliptic tokamak in all collisional regimes is investigated by the technique of partitioning the velocity space. It is found that in a tokamak of moderate elongation, particle and ion heat confinement times are increased by a factor of sigma/sup 2/, where sigma is the ratio of vertical minor radius to horizontal minor ...

Sustainable Development, EarlyView.ABSTRACT Certain attributes of large‐scale complex systems are often expressed through sets of indicators. For example, the sustainability of an entity, be it a nation, a city, an energy system, a corporation etc., can be effectively represented by indicators and corresponding data series.
