Hypoechoic nodule structure increases non-diagnostic rate of thyroid fine needle aspiration biopsy
(2021)
Aim: Thyroid fine needle aspiration biopsy (FNAB) performed with ultrasonography is an effective method in diagnosing thyroid cancer. Nevertheless, some of them have non-diagnostic results. The aim is to investigate the ...
Convolutional neural network based dictionary learning to create hash codes for content-based image retrieval
(Elsevier Science Bv, 2021)
This study investigates the suitability of sparse vectors in the dictionary learning (DL) method for content-based image retrieval (CBIR) tasks. Since DL usually performs the learning process in an unsupervised manner, it ...
An alternative approach for measuring computational thinking: Performance-based platform
(Elsevier Sci Ltd, 2021)
Educators emphasize that computational thinking is especially helpful in raising problem-solving skills, improving logical reasoning, and developing analytical thinking. In this context, the aim of this study is to develop ...
A new effective hybrid segmentation method based on C-V and LGDF
(Springer London Ltd, 2021)
Image segmentation is a significant research topic in image processing and computer vision. Active contour methods (ACMs) are widely used in image segmentation. In this paper, a new hybrid ACM segmentation model based on ...
The Roles of Social-Emotional Development, Academic Grit and Subjective Well-Being in Primary School Students' Reading-Writing Motivation
(Routledge Journals, Taylor & Francis Ltd, 2021)
This study aims to evaluate the roles of social-emotional development, academic grit and subjective well-being in reading-writing motivation. Altogether 582 fourth-grade primary school students were sampled and invited to ...
A novel hybrid deep learning approach including combination of 1D power signals and 2D signal images for power quality disturbance classification
(Pergamon-Elsevier Science Ltd, 2021)
As a result of the widespread use of power electronic equipment and the increase in consumption, the importance of effective energy policies and the smart grid begins to increase. Nonlinear loads and other loads in electric ...
Free triiodothyronine to free thyroxine ratio in the differential diagnosis of thyrotoxicosis and hyperthyroidism: A retrospective study
(Wiley-Hindawi, 2021)
Background Thyroid ultrasound, thyroid scintigraphy and radioactive iodine uptake (RAIU) tests are helpful in the differential diagnosis of thyrotoxicosis and hyperthyroidism. In the setting where these techniques are ...
The effects of charmonium on the properties of the 1++ hidden charm poles in effective field theory
(Elsevier, 2021)
In this study, the properties of the J(PC) = 1(++) hidden charm poles are analyzed under the variation of the bare 2P charmonium mass within the effective field theory proposed in Ref. [1]. The main focus of the current ...
Inflammatory response and matrix metalloproteinases in chronic kidney failure: Modulation by adropin and spexin
(Sage Publications Ltd, 2021)
Chronic kidney disease is a major global public health problem. The peptide hormones adropin and spexin modulate many physiological functions such as energy balance and glucose, lipid and protein metabolism. However, it ...
Utilizing true periodic orbits in chaos-based cryptography
(Springer, 2021)
Digital realizations of chaos-based cryptosystems suffer from lack of a reliable method for implementation. The common choice for implementation is to use fixed or floating-point arithmetic directly. However, such an ...
