Abstract

The present study focuses on the analysis of one-dimensional thermoelastic interaction in an infinite medium consisting of double poro-thermoelastic material with voids (DPTMWV) in the presence of Hall current by developing the fundamental relations in light of Eringen's nonlocal elasticity theory. A fractional-order Moore-Gibson-Thompson (MGT) heat conduction equation is introduced to the model in the context of a continuous heat source. The Caputo fractional derivative is applied in the domain of Laplace transform. The displacement, temperature, volume fractions, and stresses are determined with the help of the eigenvalue approach and the numerical inversions of these physical variables are obtained by using Zakian's algorithm. The effects of several parameters, such as Hall current, fractional order, nonlocality, and time, are graphically executed. Furthermore, the nonlocal models under different generalized thermoelasticity theories are compared to visualize the variations in the distributions corresponding to the prior mentioned variables.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
