Background/Aims Delayed bleeding after gastric endoscopic submucosal dissection (ESD) commonly occurs within 3 days, but it may also occur after 1 week following ESD, especially in antiplatelet agent users. We evaluated the risk of delayed bleeding in post-ESD ulcers using the Forrest classification. Methods Registry data on the Forrest classification of post-ESD ulcers (n=371) at 1 week or 2...

Especially in the remote sensing context, thematic classification is a desired product for coral reef surveys. This study presents a novel statistical-based image classification approach, namely Partial Least Square Discriminant Analysis (PLS-DA), capable of doing so. Three classification models were built and implemented for the images while the fourth was a combination of spectra from all thr...

the global culture concept is one of the importance and the most debatable global concepts which has not been known exactly attend to topics sequence and different views in this theme, nature and aspects related to it. this paper after glance look to the global phenomenon's and express different features try to classification of different social views in global culture concept remove some ...

Nowadays, many health groups and forums are established on the Internet, where health consumers discuss health issues and interact with each other. Although there is a large amount of user generated content about healthcare on different social media sites, few studies have applied data mining or artificial intelligence techniques for knowledge discovery on a large scale of data in this particul...

The main goal of this exploratory project was to quantify seedling density in post fire regeneration sites, with the following objectives: to evaluate the application of second order image texture (SOIT) in image segmentation, and to apply the object-based image analysis (OBIA) approach to develop a hierarchical classification. With the utilization of image texture we successfully developed a m...

This study aimed to classify patients according to their degree of dependence on nursing care (Perroca Classification System) and correlate this with the anesthetic risk (American Society of Anesthesiologists--ASA classification) in a post-anesthesia care unit. A cross-sectional study was conducted, which included 402 patients, mean age 51.57 (±16.73) years, of which 216 (54%) were female. The ...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

Background: Epilepsy surgery has become a successful treatment option for patients with drug-resistant epilepsies. Objectives: This study aimed to assess temporal lobe epilepsy (TLE) surgery outcome and its association with epilepsy duration, the presence of pre-surgical generalized tonic-clonic seizure (GTCS), and brain MRI findings. Materials & Methods: This retrospective study was perfo...

statement of problem: it is yet unclear whether fiber-reinforced composite posts can enhance the mechanical properties and prevent vertical fractures of teeth under chewing loads. purpose: the purpose of this study was to compare the fracture resistance and failure mode of endodontically treated teeth restored with three different post systems. materials and methods: thirty-six maxillary canine...
