This article is a continuation of a previously published study devoted to the interaction analysis of the national and regional economies through a twosector model. The concept is based on the proportion between the resource-rich and resourcepoor sectors. In the previous article, we showed the fundamental possibility of using this two-sector model for the study of regional economy.

Immune checkpoint inhibitors (ICIs) represent an approved treatment for various cancers; however, only a small proportion of the population is responsive to such treatment. We aimed to develop and validate a plain CT-based tool for predicting the response to ICI treatment among cancer patients.

This paper presents a new effective iterative learning control method for repetitive motion-tracking control problems of robotic manipulators. The controller is comprised of two control loops. In the inner loop, a simple proportional-derivative signal is adopted to stabilize the closed-loop system that facilitates design of the outer loop.

Ebook "Currencies, commodities and consumption" analyses the strengths and weaknesses of two alternatives to PPP. Firstly, the so-called Big Mac Index, which uses hamburger prices as a standard of measurement, and second, a less well known technique which infers incomes across countries based on the proportion of consumption devoted to food.

The present work characterized two types of fly ash, one from pulverized coal combustion and the other from fluidized bed combustion. The effects of fly ash origins, raw mix proportions, and sintering temperatures on the bloating of lightweight aggregates were studied. The raw mixtures were calculated based on Riley's SiO2 – Al2O3 – fluxing composition diagram.

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 robustness of the controller is also investigated by inserting perturbation uncertainty in all process parameters simultaneously. The results demonstrate the superior performance of the proposed IMC-PID controller in both nominal and robust cases.

This thesis develops two objectives. The first objective is to develop a new improved measure for DRPTs. To achieve the first objective, this thesis develops and tests a measure that seeks to distinguish the proportion of transactions in total RPTs that is discriminatory from the proportion that is based on legitimate business motives. The second objective of the thesis is to investigate the effectiveness of Bangladesh’s 2006 reforms for protecting minority shareholders from DRPTs. For this Oliver Williamson’s Market and Hierarchy model is used as a theoretical framework.

This paper presents the design procedures of two proportional-integral-derivative (PID) damping controllers for a generalized unified power flow controller (GUPFC) to achieve damping improvement of a four-machine system. Two PID damping controllers of the proposed GUPFC are designed to contribute adequate damping characteristics to the dominant modes of the system under various operating conditions.

Orobanche cumana is a parasitic plant that can lead to advanced losses in yield of agricultural lands cultivating sunflower, depending on the sunflower varieties and the level of contamination. In our study, genetic diversity of six O. cumana populations from the Thrace region of Turkey was determined with the help of eight SSR (microsatellite) loci. All SSR loci were polymorphic. A total of 23 alleles were determined for the analyzed 120 samples. Allele number of each SSR locus ranged from two to six. Mean number of alleles (Na = 2.271), effective allele number (Ne = 1.

In this study we hypothesize that variants in some functional classes, such as splice site regions, coding regions, DNA methylated regions and long noncoding RNA will explain more variance in complex traits than others. Two variance component approaches were used to test this hypothesis – the first determines if variants in a functional class capture a greater proportion of the variance, than expected by chance, the second uses the proportion of variance explained when variants in all annotations are fitted simultaneously.
