A cycle generative adversarial network for improving the quality of four-dimensional cone-beam computed tomography images

open access: yesRadiation Oncology, 2022
Background Four-dimensional cone-beam computed tomography (4D-CBCT) can visualize moving tumors, thus adaptive radiation therapy (ART) could be improved if 4D-CBCT were used. However, 4D-CBCT images suffer from severe imaging artifacts.

Two Decades of 4D-QSAR: A Dying Art or Staging a Comeback? [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
A key question confronting computational chemists concerns the preferable ligand geometry that fits complementarily into the receptor pocket. Typically, the postulated ‘bioactive’ 3D ligand conformation is constructed as a ‘sophisticated guess’ (unnecessarily geometry-optimized) mirroring the pharmacophore hypothesis—sometimes based on an erroneous ...

Polysaccharide‐based biomaterials in a journey from 3D to 4D printing

open access: yesBioengineering & Translational Medicine, 2023
3D printing is a state‐of‐the‐art technology for the fabrication of biomaterials with myriad applications in translational medicine. After stimuli‐responsive properties were introduced to 3D printing (known as 4D printing), intelligent biomaterials with ...

Direct Versus Indirect Measurement of Digit Ratio (2D:4D): A Critical Review of the Literature and New Data [PDF]

open access: yes, 2016
Digit ratio (2D:4D: the relative lengths of the second and fourth digits) is widely used as a correlate of prenatal sex steroids. There are two common methods of measuring 2D:4D, the direct method and the indirect method.

Digit ratio (2D:4D) and gender inequalities across nations [PDF]

open access: yes, 2014
Gender inequality varies across nations, where such inequality is defined as the disproportionate representation of one sex over the other in desirable social, economic, and biological roles (typically male over female).

Are RGB-based salient object detection methods unsuitable for light field data?

open access: yesEURASIP Journal on Image and Video Processing, 2020
Considering the significant progress made on RGB-based deep salient object detection (SOD) methods, this paper seeks to bridge the gap between those 2D methods and 4D light field data, instead of implementing specific 4D methods.

A Comprehensive Review of 4D Printing: State of the Arts, Opportunities, and Challenges

open access: yesActuators, 2023
Over the past decade, 3D printing technology has been leading the manufacturing revolution. A recent development in the field of 3D printing has added time as a fourth dimension to obtain 4D printing parts. A fabricated design created by 3D printing is static, whereas a design created by 4D printing is capable of altering its shape in response to ...
