In order to make a reliable QPE product, a quality check for rain gauge data comparing mutual rain gauge data experimented and 1) missing data ratio, 2) proportion to mean of nearly ten stations, and 3) double sum curve check was selected as thresholds to select relatively reliable rain gauge stations. As a result of the quality check for rain gauge data in May 2023, 1,299 stations were chosen, and QPE with rain gauges selected showed stable precipitation distribution.

Clinical prediction models providing binary categorizations for clinical decision support require the selection of a probability threshold, or “cutpoint,” to classify individuals. Existing cutpoint selection approaches typically optimize test-specific metrics, including sensitivity and specificity, but overlook the consequences of correct or incorrect classification.

This paper suggests a solution for the image segmentation (IS) problem with the multilevel thresholding based on one of the latest hybrid swarm computation optimization algorithms, particle swarms, and gravitational search (PSGA). The experimental results are comparable with other state-of-the-art algorithms that show that the PSGA on selected images is better than the competitors.

The study in this paper examines the causality relationship between exporting and firm productivity in an emerging market economy on the path of trade liberalization and market-oriented transition reforms. To achieve this purpose, we focused on testing whether only the most productive firms can overcome a productivity threshold to enter export markets (self-selection) or whether firms that enter export markets observe a subsequent productivity improvement (learning by exporting) using a panel data of firm-level data of manufacturing firms in Vietnam during the period 2007-2013.

Selection of an appropriate statistical significance threshold in genome-wide association studies is critical to differentiate true positives from false positives and false negatives. Different multiple testing comparison methods have been developed to determine the significance threshold; however, these methods may be overly conservative and may lead to an increase in false negatives.

In recent years, the microscopy technology for imaging cells has developed greatly and rapidly. The accompanying requirements for automatic segmentation and quantification of the imaged cells are becoming more and more. After studied widely in both scientific research and industrial applications for many decades, cell segmentation has achieved great progress, especially in segmenting some specific types of cells, e.g. muscle cells.

Sequence similarity networks are useful for classifying and characterizing biologically important proteins. Threshold-based approaches to similarity network construction using exact distance measures are prohibitively slow to compute and rely on the difficult task of selecting an appropriate threshold, while similarity networks based on approximate distance calculations compromise useful structural information.

This paper investigates the market-risk-hedging effectiveness of the Taiwan Futures Exchange (TAIFEX) stock index futures using daily settlement prices for the period from July 21, 1998 to December 31, 2010. The minimum variance hedge ratios (MVHRs) are estimated from the ordinary least squares regression model (OLS), the vector error correction model (VECM), the generalized autoregressive conditional heteroskedasticity model (GARCH), the threshold GARCH model (TGARCH), and the bivariate GARCH model (BGARCH), respectively.

Genetic gain in Testcrosses derived from heat tolerant multi-parental synthetic populations of maize
Heat stress due to prolonged high ambient temperature during critical growth stages is a serious threat to crop production worldwide. Though being a C4 crop, maize has relatively wider adaptation, however, weather extremes such as heat stress is challenging its threshold limits. There is an absolute requirement of heat tolerant cultivars in the present condition as climate change has a become reality.

Mapping of QTL associated with sorghum aphid resistance was undertaken in a recombinant inbred population derived from 296B (susceptible) x IS 18551 (Resistance) parents. Totally 2 QTLs spread across linkage group were detected at threshold LOD of 2.50. The alleles of IS 18551 contributed to increase aphid tolerance. QTL analysis across season revealed that QTL mapped on LG ‘J’ was a major one, explaining 20.4% of the observed phenotypic variance with a peak LOD value 9.2 and showed nonsignificant Q x E interaction. This major QTL flanked by two linked markers i.e.

The purpose of this paper is to examine the use of astrochemistry examples in teaching the potential threshold concepts (TCs) of physical chemistry that are contained in the recently published Physical Chemistry Anchoring Concepts Content Map (PChem-ACCM). The paper provides a brief overview of how selected astrochemical examples can be utilized to teach and learn suggested TCs that are commonly encountered in the three main overarching areas of physical chemistry curriculum, namely: chemical kinetics, quantum chemistry, and thermodynamics.

This position paper argues for an interactive approach to text understanding. The proposed model extends an existing semantics-based text authoring system by using the input text as a source of information to assist the user in re-authoring its content. The approach permits a reliable deep semantic analysis by combining automatic information extraction with a minimal amount of human intervention.
