Quality of service on ad-hoc wireless networks

, 2023
Over the last years, Mobile Ad-hoc Networks (MANETs) have captured the attention of the research community. The flexibility and cost savings they provide, due to the fact that no infrastructure is needed to deploy a MANET, is one of the most attractive possibilities of this technology.

Local Multicoloring Algorithms: Computing a Nearly-Optimal TDMA Schedule in Constant Time [PDF]

, 2009
The described multicoloring problem has direct applications in the context of wireless ad hoc and sensor networks. In order to coordinate the access to the shared wireless medium, the nodes of such a network need to employ some medium access control (MAC)

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Ultra‐Robust Conductive Hydrogels Enabled by a Gradient Bond‐Breaking Pseudo‐Drying Strategy

Advanced Science, EarlyView.
A bioinspired PVA‐ANFs hydrogel, engineered via novel gradient bond‐breaking, achieves unprecedented mechanical performance: ultrahigh strength (≈18 MPa), modulus (≈12 MPa), toughness (≈74 MJ/m3), and record fracture energy (≈269 kJ m−2). It exhibits cryogenic flexibility (−70°C), high ionic conductivity (936.3 mS m−1), and biocompatibility.

T‐2 Toxin Exploits Gut‐Derived Staphylococcus Saprophyticus to Disrupt Hepatic Macrophage Homeostasis

Advanced Science, EarlyView.
T‐2 toxin promotes the proliferation of intestinal S. saprophyticus and facilitates its translocation to the liver in piglets and mice. The translocated bacteria trigger autophagy in Kupffer cells and recruit monocytes to the liver through the nucleotide‐binding oligomerization domain 2 (NOD2) signaling pathway, alongside the M1 polarization of hepatic

Wireless ad-hoc control networks

INDIN '05. 2005 3rd IEEE International Conference on Industrial Informatics, 2005., 2005
A new concept called wireless ad-hoc control networks (WACNets), designed for distributed and remote monitoring and control is suggested in this work. Such systems represent the next stage in the evolution of distributed control and monitoring. WACNet explores a framework for organic, evolutionary and scalable method of integrating a large number of ...

Cooperative Beamforming for Wireless Ad Hoc Networks [PDF]

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
Via collaborative beamforming, nodes in a wireless network are able to transmit a common message over long distances in an energy efficient fashion. However, the process of making available the same message to all collaborating nodes introduces delays.

Developing and Refining a Knowledge Assessment Instrument for Individuals Involved in Managing Occupational Heat Stress: Paper A

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Occupational heat stress poses a critical threat to workers' health, safety, and productivity. To effectively manage this hazard, occupational health and safety (OHS) representatives must comprehensively understand heat stress, heat‐associated injury and disease outcomes, and heat mitigation measures to protect workers.
