Tailored minimal reservoir computing: On the bidirectional connection between nonlinearities in the model and in data.

We study how the degree of nonlinearity in the input data affects the optimal design of reservoir computers (RCs), focusing on how closely the model's nonlinearity should align with that of the data. By reducing minimal RCs to a single tunable nonlinearity parameter, we explore how the predictive performance varies with the degree of nonlinearity in the model. To provide controlled testbeds, we generalize to the fractional Halvorsen system, a novel chaotic system with fractional exponents.

A percolating path to green iron.

About 1.9 gigatons of steel is produced every year, emitting 8% (3.6 gigatons) of global CO in the process.

Oxidation Behavior and Integration into High Power Density Thermoelectric Generators of Commercial Half-Heusler Alloys.

Half-Heusler (HH) alloys are among the best high-temperature thermoelectric (TE) materials able to operate above 700 °C. Here, we report on a detailed experimental study of the oxidation behavior of commercial - and -type HH alloys, HfZrNiSnSb and HfZrTiCoSbSn, respectively, and of their integration into high-power-density TE generators (TEGs). Oxidation behaviors were investigated from room temperature to 800 °C in air on consolidated small pieces and large pellets using thermogravimetric/differential scanning calorimetry (TG/DSC).
