A study of the state of the theory of fuzzy sets shows that until recently in Russia there were almost no studies in the chemical sector of the economy and finance using fuzzy analysis and forecasting, although by that time all necessary prerequisites for modeling financial systems had been created. The current situation in Russia is characterized by a high degree of science lagging behind the requests of state and commercial supply chain management.

This study examined within- and over-time cross-lagged associations based on data from a quantitative questionnaire-based survey of adolescent students (T1: N= 1088; Mage = 13.70, SD = 0.53) from 23 secondary schools in Brandenburg, Germany. Results of latent cross-lagged panel design supports the mutual relations for within-time associations, which is in line with Bronfenbrenner’s model.

To study methodological approaches to employee remuneration planning taking into account the relationship between the types of supply chain management (SCM) and the staff effectiveness based on the multiple regression model and evaluation of the optimal payment times based on a dynamic model with a distributed lag. The application of the concept of sustainable supply chain management in the operation strategy of industrial enterprise seems to be a very important function. This supply chain also covers all three aspects of sustainable development: business, environmental, and social.

While cancer outcomes have improved over time, in Northern Ireland they continue to lag behind those of many other developed economies. The role of comorbid conditions has been suggested as a potential contributory factor in this but issues of data comparability across jurisdictions has inhibited efforts to explore relationships.

Assessing long-term tumor survival rates is crucial for evaluating the effectiveness of tumor treatment and burden. However, timely assessment of long-term survival in patients with pancreatic cancer is lagging in China. In this study, we applied period analysis to estimate the long-term survival of pancreatic cancer patients using data from four population-based cancer registries in Taizhou city, eastern China.

This paper investigates whether this is the case for 60 Vietnamese provinces for the time-period 1999-2010, using a system-GMM estimator and a Solow growth model augmented with human and physical capital and spatial lag covariates. We report that spatial dependence is a significant determinant of growth and conditional convergence in Vietnamese provinces. We also demonstrate that the rate of convergence decreases as the distancebetween neighbouring provinces increases.

In this paper, a proportional-integral-derivative (PID) controller cascaded with a second-order lead-lag filter is proposed for unstable second-order process with time delay. On the basis of the internal model control (IMC) principle for the two-degree-of-freedom (2DF) control system, the proposed method can achieve the enhanced performance for both disturbance rejection and set-point tracking problems.

The day-to-next day predictions between physical activity (PA) and sleep are not well known, although they are crucial for advancing public health by delivering valid sleep and physical activity recommendations. We used Big Data to examine cross-lagged time-series of sleep and PA over 14 days and nights.

There are prominent geographic disparities in the life expectancy (LE) of older US adults between the states with the highest (leading states) and lowest (lagging states) LE and their causes remain poorly understood. Heart failure (HF) has been proposed as a major contributor to these disparities. This study aims to investigate geographic disparities in HF outcomes between the leading and lagging states.

The study "Agriculture led economic growth: The case of Pakistan" aims to quantify the impact of agricultural growth on the overall economy of Pakistan. Time series analysis techniques are suitable to achieve such objectives. Time series has seen a lot of development during the recent decades. e development of concepts like that of stationarity and the tests to check it have cast doubts over the reliability of results reported by earlier studies.

This project proposes two new methods of deep neural networks and handcrafted features for damage detection. The first method uses a convolution neural network (CNN) to extract deep features in time series and Long Short Term Memory (LSTM) network to find a statistically significant correlation of each lagged feature in time series data.

The study examines the asymmetric effect of oil price on the exchange rate and stock price using the nonlinear autoregressive distributive lag (NARDL) technique on the time-series data spanning from January 1996 to September 2020. The multivariate cointegration test showed evidence of a longrun relationship among the stock price, exchange rate, and oil price. The linear Granger causality test showed that stock price is granger caused by oil price and exchange rate, and oil price is granger cause by stock price and exchange rate.
