Channel Modeling for In-body Optical Wireless Communications
Next generation in-to-out-of body biomedical applications have adopted optical wireless communications (OWCs). However, by delving into the published literature, a gap is recognised in modeling the in-to-out-of channel, since most ...
Long-Term Evaluation of the Poly(Lactic Acid) (PLA) Implants in a Horse: An Experimental Pilot Study
In horses, there is an increasing interest in developing long-lasting drug formulations, with bi-opolymers as viable carrier alternatives in addition to their use as scaffolds, suture threads, screws, pins, and ...
Amphiphilic Carboxymethyl Dextran Nanomicelles for Antibacterial Coating on Titanium
Peri-implantitis occurs at a significant rate, which is the leading cause of implant failure. The main reason for this unwanted complication is bacterial invasion and biofilm formation. To reduce the ...
Stochastic Computing Emulation of Memristor Cellular Nonlinear Networks
Cellular Nonlinear Networks (CNN) are a concept introduced in 1988 by Leon Chua and Lin Yang as a bio-inspired architecture, capable of massively parallel computation. Later on, CNN have been ...
Evaluation of Injectable Hyaluronic Acid-Based Hydrogels for Endodontic Tissue Regeneration
Dental pulp tissue engineering (TE) quests to regenerate dentin/pulp complex by combining a suitable supporting matrix, stem cells, and biochemical stimuli. Such procedures foresee a matrix that can be easily ...


Objective and Subjective Evaluation of a Passive Exoskeleton for Upper Limbs
The aim of this study was to evaluate the Hapo ms, a passive upper limbs exoskeleton developed to assist workers for tasks with arms in front of the body. Twelve ...
Multimodal Social Network Dataset Based on Goldbach Conjecture Proved Event in Zhihu
At the end of 2018, a high school student asked a question in Zhihu community, claiming that he had proved Goldbach's conjecture. The problem caused an explosive reaction and a ...
Flood Early Warning Systems using Machine Learning Techniques. Case the Tomebamba Catchment at the Southern Andes of Ecuador
Flood Early Warning Systems (FEWSs) using Machine Learning (ML) has gained worldwide popularity. However, determining the most efficient ML technique is still a bottleneck. We assessed FEWSs with three river ...
The Evolution of Hox Genes in Spiralia
The decoding of genomes of a larger number of animal species have provided further insights into the genomic Hox gene organization and with this indicated the evolutionary changes during the ...
Imagining Sustainable Human Ecosystems with Power-to-x in-situ Resource Utilisation Technology
Extensive in-situ resource utilisation (ISRU) will be essential to enable long-duration stays on Luna and Mars and reduce reliance on resupply from Earth. Early development of ISRU technologies has focused ...
