The purpose of the study "Monitoring surface water bodies changes from sentinel-2A imagery with modified normalized difference water index: Application in Dalat, Lam Dong, Viet Nam" is to identify surface water body changes using Sentinel-2 MSI (Multi-Spectral Instrument) data, one of the latest types of remote sensing satellite data. The results of the research show that by using Sentinel-2 MSI imagery, MNDWI (Modified Normalized Water Index) is the appropriate parameter to detect surface water areas in the studied area, with an overall accuracy > 0.92 and Kappa coefficient > 0.84.

The study "Drought monitoring using MODIS data and the Google Earth Engine platform, case study in Dak Lak province" was conducted to monitor drought conditions in Dak Lak province using satellite data and the GEE platform. Various drought indicators, such as the Vegetation Health Index (VHI) and the Normalized Differential Drought Index (NDDI), were obtained from multi-time MODIS satellite data and used to analyze the spatial and temporal distribution of dry conditions in Dak Lak province during the period from 2001 to 2020.

The paper deals with the task of assessing the financial condition of enterprises. To solve it, we prove the necessity of building a neural network model for supply chain. A set of financial ratios is defined as the input parameters of the model: the current liquidity ratio of the enterprise, the equity ratio, the equity turnover ratio, and the return on equity ratio. The output parameters were the types of the financial condition of enterprises: an unstable state (regression), a normal state (stable) and an absolutely stable state (progression).

When interpreting sequencing data from multiple spatial or longitudinal biopsies, detecting sample mix-ups is essential, yet more difficult than in studies of germline variation. In most genomic studies of tumors, genetic variation is detected through pairwise comparisons of the tumor and a matched normal tissue from the sample donor.

In this study we generated a whole exome sequencing benchmark dataset using the platinum genome sample NA12878 and developed an intersect-then-combine (ITC) approach to increase the accuracy in calling single nucleotide variants (SNVs) and indels in tumour-normal pairs. We evaluated the effect of alignment, base quality recalibration, mutation caller and filtering on sensitivity and false positive rate.

As the main isoforms of membranous glucose transporters (GLUT), GLUT1 involves tumorigenesis, metastasis and prognosis in a variety of cancers. However, its role in breast cancer metastasis remains to be elucidated. Here we examined its transcriptional and survival data in patients with breast cancer from several independent databases including the Oncomine, Gene Expression Profling Interactive Analysis, Gene Expression across Normal and Tumor tissue, UALCAN, cBioPortal, Kaplan-Meier Plotter and PROGgeneV2.

The objective of this study was to estimate the accuracy of transcriptome-based classifier in differential diagnosis of uterine leiomyoma and leiomyosarcoma. We manually selected 114 normal uterine tissue and 31 leiomyosarcoma samples from publicly available transcriptome data in UCSC Xena as training/validation sets.

This study aimed to build a signature on the basis of NRGs to evaluate the prognosis of HCC patients. In this study, using bioinformatic analyses of transcriptome sequencing data of HCC (n=370) from The Cancer Genome Atlas (TCGA) database, 63 differentially expressed NRGs between HCC and adjacent normal tissues were determined. 24 differentially expressed NRGs were found to be related with overall survival (OS).

Mangrove forests, typically found along tropical and subtropical coastlines, have a crucial role in preventing coastal erosion, mitigating the effects of wave actions, and safeguarding coastal habitats. This study utilized PlanetScope mangrove forests and a Combined Mangrove Recognition Index (CMRI), which was suitable for detecting mangrove cover along the coast of Tien Yen district with an overall accuracy of over 93.0% and a Kappa coefficient greater than 0.90 for the selected years.
