Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications
Advanced Materials, EarlyView.Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.

Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

SEASONALITY IN ECONOMIC MODELS
Macroeconomic Dynamics, 2001Seasonality has been a major research area in economics for several decades. The paper assesses the recent development in the literature on the treatment of seasonality in economics, and divides it into three interrelated groups. The first group, pure noise models, consists of methods based on the view that seasonality is noise contaminating the data ...

With a reclassified system of economic models, some important economic models concerning economic analysis are reviewed as absolute amount models (A2Ms), relative rate models (R2Ms), and mixed measure models (M2Ms). A2Ms include AD-AS model, Arrow-Debreu model, etc. R2Ms cover Cobb-Douglas model, Solow-Swan model, etc. M2Ms involve IS-LM model, Mundell-

Abstract Building bigger and more elaborate models will neither help us arrive at more realistic descriptions of the world nor help make our predictions more accurate. Mathematical models are just a more accurate way of describing certain complex systems and even though such a model can enhance our understanding of the problem and help ...

Entropy and Economic Modelling
Environment and Planning A: Economy and Space, 1982Entropy-maximizing models have been focused predominantly at the microscopic level of social and economic activities, their use being advocated by urban geographers, mathematicians, and microeconomists. By maintaining a sharp distinction between the behavioural and statistical aspects of entropy, various submodels may be formulated to generate the ...

Modelling Nonlinear Economic Relationships
1993Abstract This volume explains recent theoretical developments in the econometric modelling of relationships between different statistical series. The statistical techniques explored analyse relationships between different variables, over time, such as the relationship between variables in a macroeconomy.
