Technological change, capital deepening, and agricultural total factor productivity (TFP) growth: Cross‐country comparison of 18 OECD countries

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract This paper employs the data envelope analysis (DEA) to assess technological progress and its impact on agricultural total factor productivity (TFP) across 18 the Organization for Economic Cooperation and Development (OECD) countries from 1973 to 2015.

The impact of the Russia–Ukraine war on stock prices, profits and perceptions in the food supply chain

open access: yesAgribusiness, 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 ...

An extension of coupled beam method and its application to study ship's hull-superstructure interaction problems

open access: yesLatin American Journal of Solids and Structures
This 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

Universally Accurate or Specifically Inadequate? Stress‐Testing General Purpose Machine Learning Interatomic Potentials

open access: yesAdvanced 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.

On the Krein-Milman-Ky Fan theorem for convex compact metrizable sets

open access: yes, 2016
The Krein-Milman theorem (1940) states that every convex compact subset of a Hausdorfflocally convex topological space, is the closed convex hull of its extreme points.

Alpha-Concave Hull, a Generalization of Convex Hull

open access: yes, 2013
Bounding hull, such as convex hull, concave hull, alpha shapes etc. has vast applications in different areas especially in computational geometry. Alpha shape and concave hull are generalizations of convex hull. Unlike the convex hull, they construct non-convex enclosure on a set of points.

What to Make and How to Make It: Combining Machine Learning and Statistical Learning to Design New Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.
