Since the early 1990s, many authors have studied fuzzy rough set models and their application in machine learning and data reduction. In this work, we adjust the β-precision and the ordered weighted average based fuzzy rough set models in such a way that the number of theoretical properties increases. Furthermore, we evaluate the robustness of the new models a-β-PREC and a-OWA to noisy data and...

Language learning strategies, “the techniques or devices which a learner may use to acquire knowledge” (Rubin, 1975, p. 43) or more pertinently “complex, dynamic thoughts and actions, selected and used by learners with some degree of consciousness in specific contexts” (Oxford, 2017, p. 48), have been widely researched and discussed for more than forty years since the mid-1970s. Shifting the fo...

A number of technical breakthroughs in electronics and photonics made since the early 1990s have started to bring terahertz (THz)-wave technologies from laboratory demonstrators to industrial applications such as non-destructive testing, security, medicine, communications, etc. This paper overviews the latest progress in THz-wave technologies in terms of components such as sources and detectors...

Issues connected to youth victimization and well-being have been on the minds of educators, public health officials, and the media for many years. However, the worrisome stories about crimes against children that regularly fill the media have unfortunately obscured some more positive news from statistical reports on these same issues. Child victimizations of various types have been declining si...

Since the development of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the early 1990s, its application has been extended to various diseases. For pancreatic cancer, EUS-FNA can obtain specimens from the tumor itself with fewer complications than other methods. Interventional EUS enables various therapeutic options: local ablation, brachytherapy, placement of fiducial markers...

Since a review of the economics of malaria conducted in the early 1990s [24], there has been some growth in the literature, although still very little relative to the need for understanding of the economic aspects of malaria and its control. The aim of this paper is to provide a brief review of current knowledge on economics of malaria, and to identify key knowledge and research capacity needs....

Breast cancer-associated mortality has been significantly reduced since the 1990s, mainly because of early diagnosis and systemic therapeutic interventions. All three therapy components - cytostatic therapy, endocrine therapy and targeted antibody therapy - are at present necessary tools for the curative treatment of primary breast cancer. This article reviews the evidence base for the use of v...

We address the solvability of critical Lane-Emden system in a smooth bounded domain with small spherical hole radius ϵ>0. prove that admits family positive solutions concentrate around center as ϵ→0, obtaining concrete qualitative description well. To best our knowledge, this is first existence result for on domain, while non-existence star-shaped domains has been known since early 1990s due to...

Economic growth has significantly boomed carbon emissions in the global economy. However, there is an ongoing debate about economic growth–carbon emission nexus for various economies literature. This paper investigates short/long-term causal information flow between fossil-fuel-related dioxide (CO2) and (GDP) US economy spanning from 1800 to 2014. Using wavelet-based-nonparametric Granger causa...
