Authors are expected to comply with the best ethical publication practices. Misconducts such as plagiarism, data fabrication and falsification, and image manipulation will not be tolerated. These practices will result in paper rejection or retraction. Plagiarism is copying text, images, ideas, or data from another source, without appropriate citation. Data fabrication is constructing data that never occurred in real data gathering. Data falsification is manipulating research data to give a false impression. Image manipulation that could lead to misinterpretation of the original image is prohibited. However, it is allowed to technically improve images for readability.
