The $2+1$ convex hull of a finite set
, 2020 We study $\mathbb{R}^2\oplus\mathbb{R}$-separately convex hulls of finite sets of points in $\mathbb{R}^3$, as introduced in \cite{KirchheimMullerSverak2003}.

Latin American Journal of Solids and StructuresThis paper describes an extended formulation for the coupled beam method (CBM). The method is originally developed for elastic bending response analysis of passenger ships with large multi-deck superstructures. The extension is mainly performed to enable

Nanocore Shells for Effective Collection of Photocurrent in Polymer Solar Cell
Advanced Energy and Sustainability Research, EarlyView.Organic solar cells have emerged as one of the possible solar cell technologies to fabricate low‐cost and lightweight solar panels. The use of metal nanoparticles in the functional layers of thin‐film organic solar cells is found to be beneficial to improve charge transport processes in the medium.

Projections of polynomial hulls
Journal of Functional Analysis, 1973 AbstractThe following theorem is discussed. Let X be a compact subset of the unit sphere in Cn whose polynomially convex hull, X̂, contains the origin, then the sum of the areas of the n coordinate projections of X̂ is bounded below by π. This applies, in particular, when X̂ is a one-dimensional analytic subvariety V containing the origin, and in this ...

Agribusiness, EarlyView.Abstract The Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an ...

Advanced Intelligent Discovery, EarlyView.We investigate MACE‐MP‐0 and M3GNet, two general‐purpose machine learning potentials, in materials discovery and find that both generally yield reliable predictions. At the same time, both potentials show a bias towards overstabilizing high energy metastable states. We deduce a metric to quantify when these potentials are safe to use.
