Variational autoencoders (VAEs) are powerful generative models with the salient ability to perform inference. Here, we introduce a quantum variational autoencoder (QVAE): VAE whose latent process is implemented as Boltzmann machine (QBM). We show that our model can be trained end-to-end by maximizing well-defined loss-function: 'quantum' lower-bound approximation of log-likelihood. use Monte Carlo (QMC) simulations train and evaluate performance QVAEs. To achieve best performance, first...

The development of quantum-classical hybrid (QCH) algorithms is critical to achieve state-of-the-art computational models. A QCH variational autoencoder (QVAE) was introduced in reference [1] by some the authors this paper. QVAE consists a classical auto-encoding structure realized traditional deep neural networks perform inference and generation from, discrete latent space. generative process formalized as thermal sampling from quantum Boltzmann machine (QBM). This setup allows...

Folic acid is an important food additive found in most products. This research study focused on making a powerful analytical device to determine the folic concentration An electrochemical amplified sensor based paste electrode (PE) modified with CuO-CNTs and 1-butyl-2,3-dimethylimidazolium hexafluorophosphate (BDHFP) was fabricated used electro-oxidation of acid. Oxidation current improved about 2.8 times at PE/M/CuO-CNTs/BDHFP compared that PE. In addition, irreversible pH dependent...

We investigate the hypocenter distribution of aftershocks December 26, 2003 Bam earthquake M w 6.5 by using a temporal seismic network. The hypocenters distribute linearly over about 20 km in parallel with line 3.5 west geological fault and extend from south city to heavily damaged area eastern part including historical mud brick citadel “Arg‐e‐Bam”. Based on distribution, we propose schematic 3‐D structural model new that have named Arg‐e‐Bam fault. suggest occurred not but is located just...

The 2003 Bam, Iran, earthquake (Mw = 6.6) was recorded by the BAM accelerometer station. Since causative fault located just below city, main shock, a foreshock and several local aftershocks. To study scenario of rupturing, we simulated all components observed shock waveform via empirical Green's function method. 28 selected aftershocks single are used to simulate in frequency range 0.5–5 Hz. events were very close station, some small may not have similar path effects shock. Therefore, it is...

A fundamental element in seismic hazard assessment studies is the prediction of maximum values ground accelerations. This achieved through an attenuation relationship, also known as motion equation (GMPE). Seismic design structures generally assumes occurrence a large earthquake on nearby fault. The predictions from GMPE are linked to magnitude, distance, and local site conditions. Critical near‑fault motions have unique characteristics such magnitude saturation distance saturation. To...
