Hierarchical Complementary Enhanced Autoencoder Integrating Spatio‐Temporal Interaction Feature for Soft Sensor

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To address the issues of neglecting the spatiotemporal correlations among process variables, low‐level features are vulnerable to noise interference, and the gradual loss of key information layer by layer during deep network training in traditional stacked autoencoder‐based soft‐sensor models, this paper proposes a hierarchical complementary ...

Exploratory Study on Carbon Dioxide Blends With Low‐GWP Working Fluids for Medium and High‐Temperature Heat Pumps Under Step Pressure

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Photoluminescence Turn‐On Method to Determine the Kinetics of Thermally Activated Delayed Fluorescence Materials

Advanced Physics Research, EarlyView.
Thermally Activated Delayed Fluorescence (TADF) is widely exploited to achieve high‐efficiency OLEDs. TADF Emitters are normally investigated with transient photoluminescence (PL), which requires the PL to be detected over multiple orders of magnitude in time and intensity.
