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.

The Anionically All‐Boron‐Based Anti‐Perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12]
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The anionically all‐boron‐based colorless anti‐perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12] can be obtained by isothermal evaporation from aqueous solutions of the underlying pseudo‐binary components Cs2[B12H12] and Cs[BH4] or Cs[BF4]. At ambient conditions, Cs3[BH4][B12H12] crystallizes trigonally (R3¯$\overline{3}$m) and transforms reversibly ...

Coevolutionary Neural Dynamics With Learnable Parameters for Nonconvex Optimisation
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Nonconvex optimisation plays a crucial role in science and industry. However, existing methods often encounter local optima or provide inferior solutions when solving nonconvex optimisation problems, lacking robustness in noise scenarios. To address these limitations, we aim to develop a robust, efficient and globally convergent solver for ...

The Consequences of Soil Organic Carbon for Crop Yield, Farm Productivity and Profit
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT Crop choices affect soil organic carbon (SOC) stocks, allowing farmers to manipulate the amount of carbon sequestered in the soil over time. This paper examines the private and public benefits of crop rotations that sequester additional carbon across the province of Saskatchewan, Canada using a novel field‐level dataset from the Saskatchewan ...

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Economic Inquiry, EarlyView.Abstract We build an endogenous growth model that distinguishes productive and welfare government expenditures and embeds fiscal externalities. The model yields three testable hypotheses: (i) productive expenditure raises growth (Barro effect); (ii) productive expenditure generates cross‐country productivity spillovers; (iii) government expenditure ...

Financial Statement Information and Equity Value: The Role of Real Options Characteristics
Financial Management, EarlyView.ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...

Groundwater, EarlyView.Regulatory agencies in humid temperate environments rely on timely evaluations of streamflow depletion and drawdown to protect aquatic ecosystems and existing water users. We present an open‐source Python package implementing analytical solutions for estimating streamflow depletion and drawdown and supporting superposition of multiple wells and ...

Network Games With Triadic Interactions
International Economic Review, EarlyView.ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

Identification and Estimation of Large Network Games with Private Link Information
International Economic Review, EarlyView.ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...
