This study proposes a threshold method in the preprocessing stage to improve human activity classification accuracy by determining the region of meaningful information (RMI) on the spectrogram. Initially, a mask function, which is created by a certain threshold value, is applied to the input spectrogram to highlight the RMI from the micro-Doppler (m-D) signatures.

The article substantiates the idea that increasing social inequality and persistent large-scale poverty in post-Soviet Russia should be considered as one of the main reasons for the low birth rate in the country and a serious challenge to ensuring its demographic security. The authors propose a concept of demographic security and outline its primary indicators and their threshold values—the methodological basis for diagnosing and forecasting demographic processes from the perspective of Russia’s national and economic security.

The purpose of this study is to determine the pricing (premium) for disaster reinsurance program. For those, this study uses the Peak Over Threshold (POT) approach, where the method pays attention to the pattern of heavy tail behaviour on the number of victims killed due to disaster events through extreme values with a reference value called the threshold u.

In addition, chemical components of Formosa GBFS and other Vietnamese products are generally similar to those Japanese and European products and the inorganic hazardous components of Formosa GBFS are evidently lower than threshold values by Vietnamese Technical Regulation and therefore, Formosa GBFS satisfy environmental requirements when used as an alternative geo-material in construction in Vietnam.

The paper "Do pharmaceutical companies listed on Vietnam stock exchange have optimal capital structure? Evidence from threshold regression model" studies the impact of debt ratio on firm value of pharmaceutical companies listed on Vietnamese Stock Exchange from 2010 to 2017 by using threshold regression model. In this research, we exploit ROE and Tobin as a proxy for firm value. The results are indicators for us to give recommendations about financing policy to listed pharmaceutical for the upcoming years.

This paper focuses on examining the nonlinear impact of trade openness on economic growth in ASEAN countries. If the nonlinear impact exists, the author will estimate the threshold value of trade openness when it affects economic growth. Thanks to this, the author expects to discover many interesting and different things compared to previous studies. Regarding the research data, the author collected the data of Asean-5 countries (Indonesia, Malaysia, Thailand, Singapore, and the Philippines) and Vietnam in the period 2004-2019.

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.

Genetic improvement of honey bees is more difficult compared to other livestock, due to the very different reproductive behavior. Estimation of breeding values requires specific adjustment and the use of sires in the pedigree is only possible when mating of queens and drones is strictly controlled.

Optimizing cardiac stroke volume during major surgery is of interest to many as a therapeutic target to decrease the incidence of postoperative complications. Because dynamic preload indicators are strongly correlated with stroke volume, it is suggested that these indices can be used for goal directed fluid therapy. However, threshold values of these indicators depend on many factors that are influenced by surgery, including opening of the abdomen.

The purpose of this study is to determine the content of adulterated protein enhancers, ammelide (AMD) and dicyandiamide (DCD), in animal feed according to the sample preparation process including the cleaning process by solid phase extraction (SPE) and quantification by HPLC-MS/MS. Method limit detection and quantitation values for both AMD and DCD were of 5 and 10 ppb, respectively.

Syringomyelia (SM) is a debilitating condition in the cavalier King Charles spaniel (CKCS) that results in neuropathic pain and diminished quality of life. Von Frey aesthesiometry (VFA) is a method of mechanical quantitative sensory testing that provides an objective sensory threshold (ST) value and can be used to quantify neuropathic pain (NP) and monitor response to therapy.

This paper proposed a robust regression model for simple decision making in smart indoor farms. In our proposal, there are several steps to ensure the time-series data set which collected from sensor nodes in smart indoor farms are expanded to its features into new data set. The step tries to maximize features, then high corelated features with outcome in new data set will be filtered with strong threshold value.

An Giang is one of the provinces in the Mekong delta that is greatly affected by flood events, which brings damage and devastation to life and property. This study practices the application of Sentinel-1A images to monitor the distribution of flood depths in the An Giang province in 2019 as well as applies regression correlation and thresholding to scattering value analysis. The research results indicated the exponential regression model on the VV polarization images had correlation coefficients (r) in August, September, and October ranging from 0.8398 to 0.

This paper proposes a computational model of topic trust being constructed from users similarity and levels of their interaction. It is defined as function of similarity degrees in interests and levels of interaction in topics among users. Based on this model, we may estimate trustworthy values among peers in all cases with some direct and indirect interaction or without any interaction. The proposed approach may overcome limitation in the high computational cost of propagation methods based on graph models.

The impacts of waste on shrimp culture environment are determined through analyzing the results of measuring water quality criteria in the pond, thereby assessing the efficiency of waste removal of the equipment. The measurement results show that water quality parameters reach a value within the threshold if operating a waste suction device once per day. The benefits of waste remover operate are to help save the cost of labor to clean the pond bottom, protect workers' health.
