Not Always Sparse: Flooding Time in Partially Connected Mobile Ad Hoc Networks [PDF]

, 2013
In this paper we study mobile ad hoc wireless networks using the notion of evolving connectivity graphs. In such systems, the connectivity changes over time due to the intermittent contacts of mobile terminals.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

Securing DSR with mobile agents in wireless ad hoc networks

Egyptian Informatics Journal, 2011
Ad hoc wireless network consists of a set of wireless nodes communicating with each other without a pre-defined infrastructure. They communicate by forwarding packets which can reach wireless nodes that do not exist in the range of the direct radio ...

Digital Microneedles for Multiplexed Transdermal Sensing via Fluorescent QR Codes

Advanced Materials, EarlyView.
Digital fluorescent microneedles encode biochemical information in skin into scannable QR codes through threshold‐activated probes that generate binary on/off signals. By transforming analog fluorescence into discrete digital patterns, this platform enables calibration‐free, multiplexed transdermal sensing of physiologically relevant biomarkers ...

Enhanced group-based wireless ad-hoc sensor network protocol

International Journal of Distributed Sensor Networks, 2016
Communication is the major energy consumption source in wireless ad-hoc sensor networks. Thus, an efficient trade-off between the energy cost of the communication and network’s performance is a key challenge in conceiving a wireless ad-hoc sensor network.
