Determining Exchangeable Base Cations in Forest Soils: A Comparison of Three Methods

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Accurately determining exchangeable base cations is critical for assessing base cation depletion in acid forest soils, where various extraction methods may yield different results. Aim The aim was to quantify differences in the effectiveness of BaCl2, NH4OAc (pH 7), and Cohex methods in extracting base cations from acid forest soils

Probably Approximately Correct Nash Equilibrium Learning

, 2020
We consider a multi-agent noncooperative game with agents' objective functions being affected by uncertainty. Following a data driven paradigm, we represent uncertainty by means of scenarios and seek a robust Nash equilibrium solution.

Confirming existing parameterizations for methane gas transfer velocity in lakes based on direct and high‐frequent methods

Limnology and Oceanography Letters, EarlyView.
Abstract Freshwater systems are important sources of atmospheric methane (CH4). However, estimated emissions are associated with high uncertainties due to limited knowledge about the temporal variability in emissions and their associated controls, such as air–water gas transfer velocity.

Voracity, growth and welfare [PDF]

This paper explores some implications of the comparison between feedback Nash and Stackelberg equilibria for growth and welfare in a `voracity' model. We show that as compared to the Nash equilibrium, the Stackelberg equilibrium involves a lower growth ...

Sales or Profits? Managerial Decision‐Making in a Duopoly With Symmetric and Asymmetric Costs

Managerial and Decision Economics, EarlyView.
ABSTRACT The paper examines the performance of firms when managers can choose sales or profit maximization strategies and when costs can be symmetric or asymmetric. Three competitive scenarios are examined: both firms choose profit maximization strategies, both firms choose sales maximization strategies, and one firm chooses profit and its rival ...

Correlated Equilibria, Good and Bad: An Experimental Study [PDF]

We report results from an experiment that explores the empirical validity of correlated equilibrium, an important generalization of the Nash equilibrium concept. Specifically, we seek to understand the conditions under which subjects will condition their

Contracting Institutions and R&D Collaboration Between Nonrivals in Competitive Industry Equilibrium

Managerial and Decision Economics, EarlyView.
ABSTRACT In a duopoly model, one firm has the option to collaborate in R&D with a third party. Although collaboration can expedite innovation, the third party may unintentionally leak the innovation to the rival firm. Engaging in R&D collaboration can make the rival firm anticipate a free ride, which weakens its incentives for R&D spending.

On the role of non-equilibrium focal points as coordination devices [PDF]

Considering a pure coordination game with a large number of equivalent equilibria, we argue, first, that a focal point that is itself not a Nash equilibrium and is Pareto dominated by all Nash equilibria, may attract the players' choices.

Breaking Boundaries: Chronic Diseases and the Frontiers of Immune Microenvironments

Med Research, EarlyView.
ABSTRACT The immune microenvironment includes immune cells, cytokines, extracellular matrix, vesicles, etc. The interactions between these components form a unique local immune microecology. Although immunity serves as the defense against external pathogens, aberrant immune activation often contributes to disease development.
