We present a novel information theoretic approach to image segmentation. We cast the segmentation problem as the maximization of the mutual information between the region labels and the image pixel intensities, subject to a constraint on the total length of the region boundaries. We assume that the probability densities associated with the image pixel intensities within each region are completely unknown a priori, and we formulate the problem based on nonparametric density estimates. Due to the

PURPOSE: To develop an automatic deep feature classification (DFC) method for distinguishing benign angiomyolipoma without visible fat (AMLwvf) from malignant clear cell renal cell carcinoma (ccRCC) from abdominal contrast-enhanced computer tomography (CE CT) images. METHODS: A dataset including 80 abdominal CT images of 39 AMLwvf and 41 ccRCC patients was used. We proposed a DFC method for differentiating the small renal masses (SRM) into AMLwvf and ccRCC using the combination of hand-crafted a

A fully coupled numerical model is presented for the water-table fluctuation and land deformation in partially saturated soils due to surface loading. This numerical model is developed based on the poroelastic governing equations for groundwater flow in deforming variably saturated porous media and the Galerkin finite element method. The numerical model is verified and validated against a one-dimensional consolidation problem concerning surface loading on a soil column which has six different in

This article surveys marriage immigration from the P hilippines to S outh K orea, the public policies of both governments, and ongoing developments, challenges, and their implications for future policy. Policies in both countries provide the context in which international marriages occur and impact the sociocultural, political, economic life of marriage immigrants and their “multicultural families.” Philippine policies are still generally limited to a ban on commercial brokerage and provision of

This explores how the fourth industrial revolution (FIR) affects developing countries, specifically in the case of the Philippines. It presents an alternative account to the claim that the world is ready to enter the FIR. The analyses show that the readiness of the Philippines for FIR is not the same as developed and industrialized countries. The authors argue that developing countries like the Philippines will not go through FIR in the same way the developed countries do, given their different

Deep learning has been increasingly utilized in the medical field and achieved many goals. Since the size of data dominates the performance of deep learning, several medical institutions are conducting joint research to obtain as much data as possible. However, sharing data is usually prohibited owing to the risk of privacy invasion. Federated learning is a reasonable idea to train distributed multicenter data without direct access; however, a central server to merge and distribute models is nee

Most research on Official Development Assistance (ODA) targeted the recipients, but this study examines the effect of ODA on the donor's exports to the recipient. To do this, a panel analysis was carried out with ODA and macroeconomic data on the United States and 33 other countries from 1999 to 2009. The results are summarized as follows: (1) The economic influence on the donor varies with the recipient's localization effort. (2) High-tech exports to the recipient are independent of ODA. (3) In

Recent studies on immigration in East Asia are focusing on female marriage immigration, the migration of large numbers of women from developing countries to marry men from industrialized countries like South Korea. Typically lost in the discourse however, are international marriages involving foreign grooms, once the more dominant trend in South Korea before the mid-1990s. This article explains how trends in international marriages in South Korea reversed in the mid- 1990s and how marriages invo

The 4th industrial revolution has been a hot topic in various societies for several overlapping reasons. It may be a huge wave for researchers to navigate through. In this context, research institutions are not different from major industrial sectors, in that both consider the 4th revolution a major turning point as well as a threat. Today’s industries and research institutions are knowledge-intensive in nature. Consequently, their potential for survival depends on scientific and technological a
