A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Energy Conversion and Economics, EarlyView.Abstract The rapid growth of distributed energy resources (DERs) is reshaping the operational landscape of transmission and distribution networks, creating new challenges for maintaining system‐wide security, economic efficiency and flexibility. Transmission‐distribution (T‐D) coordination has emerged as an essential paradigm for facilitating multi ...

Convex sets, convex cones, affine spaces and affine cones
, 1996 After introducing the concepts of a convex set, an affine space resp. a convex cone as subcases and last not least an affine cone as common subsubcase in an axiomatic manner by requiring the closedness against corresponding combination maps the author considers maps \(f:X\to Y\) between such sets \(X,Y\). He defines a map \(f\) between convex sets as a

IET Smart Energy Systems, EarlyView.An adaptive chance‐constrained hybrid SOCP‐Based ACOPF for coordinated optimisation of integrated source–grid–load–storage systems is presented. The coordinated optimisation of integrated source–grid–load–storage (SGLS) systems is challenged by renewable energy uncertainty, complex industrial load characteristics and stringent policy constraints ...

Optimal Operation Strategy of Multiterminal AC–DC Interconnected Distribution Networks With SOP
IET Smart Energy Systems, EarlyView.To improve the operational economy of distribution networks with high penetration of renewable energy, this paper studies the AC–DC interconnected distribution networks with multi‐terminal soft open points (SOPs) and its optimal operation strategy. ABSTRACT To improve the operational economy of distribution networks with high penetration of renewable ...

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Discrete dynamics and supergeometry
Journal of High Energy PhysicsWe formulate a geometric measurement theory of dynamical classical systems possessing both continuous and discrete degrees of freedom. The approach is covariant with respect to choices of clocks and naturally incorporates laboratories.

Updated Chorotypes of Terrestrial Vertebrates Shed New Light on Zoogeographical Regions in China
Integrative Zoology, EarlyView.Chorotype represents a fundamental concept for identifying groups of species that share similar distribution patterns. However, the last comprehensive revision of animal chorotypes in China was performed more than a decade ago. Here, we update the chorotype classifications for 1040 species and propose an updated zoogeographical regionalization scheme ...
