Advancements in flexible memristors for neuromorphic computing: Materials, mechanisms, and applications in synaptic emulation

open access: yesFlexMat, EarlyView.
Memristors, as the fourth fundamental passive circuit element, are promising devices that can mimic synaptic functions in neural networks due to their nonlinear memory characteristics. This paper reviews recent advancements in material selection, resistive switching mechanisms, and flexible memristor architectures for artificial neural networks ...

Modeling and Forecasting Stochastic Seasonality: Are Seasonal Autoregressive Integrated Moving Average Models Always the Best Choice?

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT In this paper, we study models for stochastic seasonality and compare the well‐known SARIMA models to Seasonal Autoregressive Unit Root Moving Average (SARUMA) models. SARUMA models assume that the polynomial of the stationarizing differencing operator has roots on the unit circle at some seasonal frequencies, while SARIMA models impose roots ...

Influence of Post‐Harvest Treatments on Antioxidant Potential and Metabolomics Profile of Coffee Beans

open access: yesFuture Postharvest and Food, EarlyView.
(1) The secondary metabolite profile of coffee beans was determined. (2) Processing affects not only the metabolite profile but also the volatile compound content. (3) Caffeine was the most abundant metabolite in all samples. (4) The fermentation‐roasting treatment improved the metabolite profile, whereas roasting, fermentation and soaking followed by ...
