Beacon Success Rate versus Gateway Density in Sub-GHz Sensor Networks.
Sensors (Basel)
November 2023
Article Synopsis
- Multiple Gateways (GWs) enhance IoT sensor connectivity in a Wide Area Network (WAN) by facilitating diverse connections, but they also risk interference and collisions due to overlapping beacon transmissions.
- This study analyzes intra-network interference, proposing a new collision model that accounts for the Medium Access Control (MAC) and Physical (PHY) layers, focusing on the effects of collisions on packet loss rates.
- Performance evaluations suggest that increasing beacon intervals and using frequency hopping can minimize beacon loss rates, albeit with increased acquisition latency; meanwhile, higher GW densities can decrease discovery latency due to more available beacons.
Effect of chemopreventive agents on differentiation of mouse embryonic stem cells.
Front Biosci (Elite Ed)
January 2012
Chemopreventive agents are derived from edible plants and from ancient time is a part of daily intake for many humans and animals. There are several lines of compelling evidence from epidemiological, clinical and laboratory studies that these dietary constituents are associated in reducing cancer risks. However, developmental toxicity of these natural compounds cannot be excluded.

CyA was incorporated into SLNs that consisted of stearic acid, trilaurin or tripalmitin lipid solid cores in order to enhance drug solubility. The process was conducted by varying lipid compositions, drug initial loading and applied homogenization pressure.

The produced SLNs consisted of stearic acid, triluarin or tripalmitin as lipid matrixes and various stabilizers. The produced empty and IBU-loaded SLNs were characterized for particle size stability over 8 months.
