BACKGROUND/AIMS The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. METHODS We identified inpatient PUB patien...

This paper presents a continuous-time recurrent neural-network model for nonlinear optimization with any continuously differentiable objective function and bound constraints. Quadratic optimization with bound constraints is a special problem which can be solved by the recurrent neural network. The proposed recurrent neural network has the following characteristics. 1) It is regular in the sense...

Ensemble deep learning can combine strengths of neural network and ensemble gradually becomes a new emerging research direction. However, the existing methods either lack theoretical support or demand large integrated models. To solve these problems, in this paper, Ensembles Gradient Boosting Recurrent Neural Network (EGB-RNN) is proposed, which combines gradient boosting framework with three t...

background: a dramatic increase in healthcare expenditures is a major health policy concern worldwide. understanding factors that underlie the growth in healthcare expenditures is essential to assist decision-makers in finding best policies to manage healthcare costs. we aimed to examine the determinants of healthcare spending in iran over the periods of 1978-2011. methods: a time series analys...

I ntisari – Pasar ritel di Indonesia semakin berkembang seiring bertambahnya penduduk dan daya beli. Peluang ini harus dimanfaatkan, namun dalam bisnis ritel, kadangkala terjadi keadaan Out of Stock maupun over stock toko. Untuk mengatasi hal tersebut, kita bisa mengatasinya dengan melakukan peramalan atau prediksi penjualan yang akan masa mendatang. Ada beberapa macam metode untuk peramalan, s...
