Performance of evolutionary optimized machine learning for modeling total organic carbon in core samples of shale gas fields

引用

Petroleum 2024年第1期10卷 150-164页

作者： Leonardo Goliatt c.M.Saporetti L.c.Oliveira E.Pereira Department of computational and Applied Mechanics Federal University of Juiz de Fora Department of computational Modeling Polytechnic Institute Rio de Janeiro State University Petrobras Department of Stratigraphy and Paleontology Rio de Janeiro State University

Rock samples' TOc content is the best indicator of the organic matter in source rocks. The origin rock samples' analysis is used to calculate it manually by specialists. This method requires time and resources because it relies on samples from many well intervals in source rocks. Therefore, research has been done to aid this effort. Machine learning algorithms can estimate total organic carbon instead of well logs and stratigraphic studies. In light of these efforts, the current work present a study on automating the total organic carbon estimation using machine learning approaches improved by an evolutionary methodology to give the model flexibility and precision. Genetic algorithms, differential evolution, particle swarm optimization, grey wolf optimization, artificial bee colony, and evolution strategies were used to improve machine learning models to predict TOc. The six metaheuristics were integrated into four machine learning methods: extreme learning machine, elastic net linear model, linear support vector regression, and multivariate adaptive regression splines. core samples from the YuDong-Nan shale gas field, located in the Sichuan basin, were used to evaluate the hybrid strategy. The findings show that combining machine learning models with an evolutionary algorithms in a hybrid fashion produce flexible models that accurately predict TOc. The results show that, independent of the metaheuristic used to guide the model selection, optimized extreme learning machines attained the best performance scores according to six metrics. Such hybrid models can be used in exploratory geological research,particularly for unconventional oil and gas resources.

A Study of Zoledronic Acid as Neo-Adjuvant, Perioperative Therapy in Patients with Resectable Pancreatic Ductal Adenocarcinoma

引用

Journal of cancer Therapy 2013年第3期4卷 797-803页

作者： Dominic E. Sanford Matthew R. Porembka Roheena Z. Panni Jonathan B. Mitchem Brian A. Belt Stacey M. Plambeck-Suess Goldie Lin David G. DeNardo ryan c. fields William G. Hawkins Steven M. Strasberg craig Lockhart Andrea Wang-Gillam Simon Peter Goedegebuure David c. Linehan Alvin J. Siteman cancer center St. Louis USA Department of Medicine School of Medicine Washington University St. Louis USA Department of Surgery School of Medicine Washington University St. Louis USA

Background: Pancreatic ductal adenocarcinoma (PDAc) is an aggressive malignancy characterized by abundant granulocytic myeloid-derived suppressor cells (G-MDSc = cD45+/Lin﹣/cD33+/cD11b+/cD15+), which infiltrate tumors and suppress anti-tumor immunity. We have previously demonstrated in a murine model of PDAc that zoledronic acid (ZA) depletes G-MDSc resulting in decreased tumor growth and improved survival. We report here the results of a phase 1 clinical trial (NcT00892242) using ZA as neo-adjuvant, perioperative therapy in patients with non-metastatic, resectable pancreatic adenocarcinoma. Methods: Eligible PDAc patients received ZA (4 mg) IV 2 weeks prior to surgery. Patients then received 2 additional doses of ZA 4 weeks apart. Blood and bone marrow were obtained from patients prior to treatment with ZA and 3 months after surgery for analysis of G-MDSc by flow cytometry. Results: Twenty-three patients received pre-operative ZA with at least 6 months of follow-up. Only 15 PDAc patients had nonmetastatic PDAc, which was amenable to resection. ZA was well tolerated, and all adverse events were grade 1 or 2. The most common adverse events were fatigue, abdominal pain/discomfort, anorexia, and arthralgia. Of resected PDAc patients treated with ZA, 1- and 2-year overall survival (OS) was 85.7% and 33.3%, respectively, with a median OS of 18 months. This group had a 1- and 2-year progression-free survival (PFS) of 26.9% and 8.9%, respectively, with a median PFS of 12 months. The prevalence of G-MDSc was unchanged in the blood and bone marrow of PDAc patients pre- and post-treatment with ZA. conclusion: ZA is safe and well tolerated as neo-adjuvant, peri-operative therapy in PDAc patients. In this small study, we did not observe a difference in OS or PFS compared to historical controls. Also, there was no difference in the prevalence of G-MDSc in the blood and bone marrow of PDAc patients pre- and post-treatment with ZA.

The layer Hall effect describes electrons spontaneously deflected to opposite sides at different layers, which has been experimentally reported in the MnBi2Te4thin films under perpendicular electric fields. Here, we reveal a universal origin of the layer Hall effect in terms of the so-called hidden Berry curvature, as well as material design principles. Hence, it gives rise to zero Berry curvature in momentum space but non-zero layer-locked hidden Berry curvature in real space. We show that, compared to that of a trivial insulator, the layer Hall effect is significantly enhanced in antiferromagnetic topological insulators. Our universal picture provides a paradigm for revealing the hidden physics as a result of the interplay between the global and local symmetries, and can be generalized in various scenarios.
