Microsc Res Tech

November 2024

Department of Electrical and Electronics Engineering, Faculty of Engineering and Architecture, Kastamonu University, Kastamonu, Turkey.

This study examined the influence of growth temperature and dopant concentration on the properties of Gd- and Ni-doped zinc oxide nanorods (ZnO NRs). ZnO seed layers were deposited on glass substrates using a sol-gel and dip-coating approach. Gd- and Ni-doped ZnO NRs were hydrothermally grown on the seed layers at different temperatures such as 75, 90, and 105°C for a constant growth time of 5 h.

Article Synopsis
  • Hypoglycaemia in diabetes involves abnormal glucose levels accompanied by symptoms, while Munchausen Syndrome (MS) entails individuals intentionally faking symptoms for secondary gain.
  • The report discusses a case of a 28-year-old woman with type I diabetes who repeatedly induced hypoglycemia attacks to seek unnecessary medical attention.
  • Understanding Munchausen Syndrome is crucial for healthcare providers to avoid misdiagnosing patients and to prevent costly and unnecessary medical procedures.

Spatio-temporal characterisation and compensation method based on CNN and LSTM for residential travel data.

PeerJ Comput Sci

May 2024

Faculty of Engineering, Department of Electrical and Electronics Engineering, Bolu Abant Izzet Baysal University, Bolu, Turkey.

Currently, most traffic simulations require residents' travel plans as input data; however, in real scenarios, it is difficult to obtain real residents' travel behavior data for various reasons, such as a large amount of data and the protection of residents' privacy. This study proposes a method combining a convolutional neural network (CNN) and a long short-term memory network (LSTM) for analyzing and compensating spatiotemporal features in residents' travel data. By exploiting the spatial feature extraction capability of CNNs and the advantages of LSTMs in processing time-series data, the aim is to achieve a traffic simulation close to a real scenario using limited data by modeling travel time and space.

Background/aim: The distinctive liver framework is converted into structurally abnormal nodules as a consequence of tissue fibrosis in cirrhosis. Cardiac dysfunction in cirrhosis was described, and the term "cirrhotic cardiomyopathy (CCM)" was coined to describe this syndrome. Recent research has shown that the contractile characteristics of the right ventricular outflow tract (RVOT) have a significant impact on right ventricular functions.
