Performance Analysis of Dense Small Cell Networks With Practical Antenna Heights Under Rician Fading
IEEE Access, 2018 In this paper, we examine the combined impacts of distance-dependent Rician fading channel model and the absolute difference between the heights of base station (BS) and user equipment (UE) antennas on the coverage probability and the area spectral ...

Advanced Healthcare Materials, EarlyView.A thermo‐responsive poly(2‐oxazoline)‐based injectable formulation is developed to modulate intraocular pressure (IOP) in both normal and hypotonic eyes. By adjusting the PEG content, the aggregation behavior is finely tuned, enabling IOP elevation without long‐term deposition.

A Geometry-Based Modelling Approach for the Line-of-Sight Probability in UAV Communications
IEEE Open Journal of the Communications SocietyThis paper presents a geometry-based three-dimensional Probability of Line of Sight $(P_{\mathrm {LoS}})$ model for generic urban environments. The existing $P_{\mathrm {LoS}}$ models are mostly empirical, based on measurements or ray-tracing ...

Line of Sight(LoS) Probability Prediction for Satellite and HAPs Communication in Trabzon, Turkey
International Journal of Applied Mathematics, Electronics and Computers, 2016 The knowledge of Line of Sight (LoS) probability is curicial to estimate signal attenuation correctly in mobile wireless communication. Especially in built-up areas, more accurate LoS probability determination helps to obtain more realistic propagation models or path loss models.

Controllable Dynamic Mechanical Cell Stimulation using Magnetically Actuated Artificial Cilia
Advanced Healthcare Materials, EarlyView.This paper introduces a platform based on magnetic artificial cilia for providing controllable dynamic mechanical stimulation to single cells, suitable for investigating large cell populations and enabling live cell imaging. Proof‐of‐principle experiments show that cell morphology is strongly influenced by the artificial cilia, that cellular forces can
