For this minimal secure computation problem, the authors propose a novel coding scheme built from two steps. First, the function to be computed is expanded such that it can be recovered while additional information might be leaked. Second, a randomization step is applied to the expanded function such that the leaked information is protected. The authors implement this expand-and-randomize coding scheme with two algebraic structures—the finite field and the modulo ring of integers, where the expansion step is realized with the addition operation and the randomization step is realized with the multiplication operation over the respective algebraic structures.</p>I Cannot See You—The Perspectives of Deaf Students to Online Learning during COVID-19 Pandemic: Saudi Arabia Case Study2022-01-14T16:33:20-06:00https://digital.library.unt.edu/ark:/67531/metadc1877587/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1877587/"><img alt="I Cannot See You—The Perspectives of Deaf Students to Online Learning during COVID-19 Pandemic: Saudi Arabia Case Study" title="I Cannot See You—The Perspectives of Deaf Students to Online Learning during COVID-19 Pandemic: Saudi Arabia Case Study" src="https://digital.library.unt.edu/ark:/67531/metadc1877587/small/"/></a></p><p>This article investigates the e-learning experiences of deaf students, focusing on the college of the Technical and Vocational Training Corporation (TVTC) in the Kingdom of Saudi Arabia (KSA).

The effects of the chemical composition, gradient fiber structure, and mesopore structure of the bamboo were also investigated. The results demonstrate that the hygroscopicity of bamboo gradually increases from the outer to the inner layer along the thickness of the culm wall, which is related to the gradient distribution of the fibers. The structure–function relationships between the chemical composition, multi-scale structure, and hygroscopicity identified in this study provide a theoretical basis for bamboo drying and storage technology, as well as the processing and application of bamboo fiber-based composites.</p>Preface: International Conference on Recent Advancements in Biomedical Engineering - 20212022-01-14T16:32:08-06:00https://digital.library.unt.edu/ark:/67531/metadc1877574/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc1877574/"><img alt="Preface: International Conference on Recent Advancements in Biomedical Engineering - 2021" title="Preface: International Conference on Recent Advancements in Biomedical Engineering - 2021" src="https://digital.library.unt.edu/ark:/67531/metadc1877574/small/"/></a></p><p>This article showcasing the editorial team welcomes all readers to the proceedings of International Conference on Recent Advancements in Biomedical Engineering (ICRABE-2021).
