Prediction of the compressive strength of high-performance self-compacting concrete by an ultrasonic-rebound method based on a GA-BP neural network.

PLoS ONE, 2021
To address the problem of low accuracy and poor robustness of in situ testing of the compressive strength of high-performance self-compacting concrete (SCC), a genetic algorithm (GA)-optimized backpropagation neural network (BPNN) model was established ...

Monoallelic POLR3A Variants Cause Early‐Onset Peripheral Neuropathy

Annals of Neurology, EarlyView.
Objective Biallelic variants in genes encoding the RNA polymerase III complex (Pol III) cause a spectrum of neurological disorders primarily affecting the central nervous system. Monoallelic variants have been reported in the POLR3B subunit only, associated with neurodevelopmental disorder, epilepsy, and peripheral neuropathy.

Applying Artificial Intelligence to Improve On-Site Non-Destructive Concrete Compressive Strength Tests

Crystals, 2021
In the construction industry, non–destructive testing (NDT) methods are often used in the field to inspect the compressive strength of concrete. NDT methods do not cause damage to the existing structure and are relatively economical.

Reliability Comparison of Schmidt Rebound Hammer as a Non- Destructive Test with Compressive Strength Tests for different Concrete Mix [PDF]

, 2019
One of the most important concrete properties for structural concrete design or re- design is the compressive strength, it gives information on the characteristics of concrete. This strength measure is obtained through standardized crushing tests on
