Solving PDE-constrained Control Problems using Operator Learning [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2021
The modeling and control of complex physical systems are essential in real-world problems. We propose a novel framework that is generally applicable to solving PDE-constrained optimal control problems by introducing surrogate models for PDE solution ...

The Yin and the Yang of Treatment for Chronic Hepatitis B—When to Start, When to Stop Nucleos(t)ide Analogue Therapy

open access: yesViruses, 2020
Over 257 million individuals worldwide are chronically infected with the Hepatitis B Virus (HBV). Nucleos(t)ide analogues (NAs) are the first-line treatment option for most patients. Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are both potent,

O PDE E A CONTRIBUIÇÃO PARA A FORMAÇÃO CONTINUADA DO PROFESSOR PEDAGOGO DOS NÚCLEOS DE EDUCAÇÃO DO SUDOESTE DO PARANÁ

open access: yesRevista Prática Docente, 2021
Nos anos 2000, no Paraná, pesquisas apontaram para a fragmentação nos cursos de formação continuada, o que contribuiu para a criação do Programa de Desenvolvimento Educacional (PDE). Nesse sentido, problematizamos os limites e as possibilidades do PDE na

Prostate sarcomas: A radiological mimic for benign prostatic hyperplasia

open access: yesUrology Case Reports, 2020
Leimyosarcomas arising from the stroma of the prostate are very rare, accounting for 0.1% of malignancies. We describe a case that closely mimicked benign prostatic hypertrophy on magnetic resonance imaging.

Considerations for Permitted Daily Exposure Calculation for Contaminants in Medicinal Products Manufactured in Shared Facilities

open access: yesРегуляторные исследования и экспертиза лекарственных средств, 2022
The manufacture of different medicinal products in shared facilities creates a risk of cross-contamination. One of the approaches to select the limits for possible contaminants is based on calculating the permitted daily exposure (PDE), i.e.

PDE-Net 2.0: Learning PDEs from Data with A Numeric-Symbolic Hybrid Deep Network [PDF]

open access: yesJournal of Computational Physics, 2018
Partial differential equations (PDEs) are commonly derived based on empirical observations. However, recent advances of technology enable us to collect and store massive amount of data, which offers new opportunities for data-driven discovery of PDEs. In

PDE-constrained Models with Neural Network Terms: Optimization and Global Convergence [PDF]

open access: yesJournal of Computational Physics, 2021
Recent research has used deep learning to develop partial differential equation (PDE) models in science and engineering. The functional form of the PDE is determined by a neural network, and the neural network parameters are calibrated to available data.

The Signature Kernel Is the Solution of a Goursat PDE [PDF]

open access: yesSIAM Journal on Mathematics of Data Science, 2020
Recently, there has been an increased interest in the development of kernel methods for learning with sequential data. The signature kernel is a learning tool with potential to handle irregularly sampled, multivariate time series.
