FlexMat, EarlyView.A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Forecasting Financial Assets Using Recursive Clustering Approach
Journal of Forecasting, EarlyView.ABSTRACT Machine learning‐based forecasting has been gaining attention for its flexibility and adaptability. Given the dynamics of temporal data, clustering can be an effective approach for improving forecasting accuracy. While clustering for classification typically considers all observations in the data to effectively divide the data into clusters ...

Journal of Forecasting, EarlyView.ABSTRACT This paper presents a method for forecasting limit order book durations using a self‐exciting flexible residual point process. High‐frequency events in modern exchanges exhibit heavy‐tailed interarrival times, posing a significant challenge for accurate prediction.

Bayesian Multivariate Two‐Stage Volatility‐Return Models (MTS‐VR)
Journal of Forecasting, EarlyView.ABSTRACT This paper develops a class of models to capture the joint dynamics of asset returns and multivariate volatility. Owing to its two‐stage construction, this class is referred to as the multivariate two‐stage volatility‐return (MTS‐VR) model.

Tail Risk Transmission in Agricultural and Energy Markets
Journal of Futures Markets, EarlyView.ABSTRACT This paper examines downside hedging, tail diversification, and extreme tail risk transmission between crude oil and agricultural commodity futures over two decades. We develop complementary indicators of downside dependence, including sign‐switching frequency and persistence, to assess tail risk dynamics, hedging effectiveness, and associated

Geological Journal, EarlyView.Energy security risk has a positive impact on material footprint. Renewable energy consumption reduces material footprint. ABSTRACT Following a high economic growth path, the group of G7 economies is found to be utilising more and more material, causing a material footprint (MF), which in turn contributes to pollution.

From Physiology to Bioheat Simulation: A Data‐Driven Framework for Core Temperature Initialization
Heat Transfer, EarlyView.ABSTRACT Accurate initialization of core body temperature is a critical yet often overlooked component of bioheat transfer models, particularly when such models are applied to heterogeneous populations and real‐world environmental conditions. Conventional bioheat simulations typically rely on fixed or idealized core body temperature values derived from
