We study two and three-point tree-level amplitudes of open strings.These amplitudes are reduced from higher-point correlation functions by using mostly BRST exact operators for gauge fixing.For simplicity, we focus on an open string tachyon.The two-point amplitude of open string tachyons is reduced from a three-point function of two tachyon vertex

Background In recent years, interactions between nutrition professionals (NPs) and the food industry, such as sponsorship arrangements, have raised concerns, particularly as these may negatively F-Connector impact the trustworthiness and credibility of the nutrition profession.This study aimed to map the literature and identify knowledge gaps regar

The article compares both static and dynamic theories of economic growth, highlights the basic provisions of the theory of endogenous growth and shows the decisive role of innovation as a trigger for technological shifts that subsequently lead to economic and social changes.Particular attention is paid to the study of the influence of human capital

1965 was a watershed year in the life of Steve Reich.Following numerous experiments with magnetic tape, he had, while creating his tape piece It’s Gonna Rain, identified a fascinating process that would serve as the basic compositional tool of his output until about 1971, and as a foundational component of his output thereafter.Reich’s preoccup

Human Activity Recognition (HAR) is increasingly used in a variety of applications, including health care, fitness tracking, and rehabilitation.To reduce the impact on the Toys user’s daily activities, wearable technologies have been advanced throughout the years.In this study, an improved smart insole-based HAR system is proposed.The impact of d
