On Achievable Rate Region of Multiple Coordinated Multiple Access Channels [PDF]
, 2011 Coordination between two or more multiple access channel (MAC) receivers can enlarge the achievable rate region of the whole system. This paper focuses on coordination by sharing the codebooks of the users between the receivers of MACs.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

QTSAC: An Energy-Efficient MAC Protocol for Delay Minimization in Wireless Sensor Networks
IEEE Access, 2018 Millions of sensors are deployed to monitor the smart grid. They consume huge amounts of energy in the communication infrastructure. Therefore, the establishment of an energy-efficient medium access control (MAC) protocol for sensor nodes is challenging ...

Molecular Oncology, EarlyView.Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Causal state quantization with or without cribbing for the MAC with a state-cognizant receiver
AIMS MathematicsA two-to-one memoryless state-dependent multiple-access channel is studied in a setting where helpers that observe the state sequence causally provide rate-limited (lossy) causal descriptions of it to the encoders.

DECREASING THE RA COLLISION IMPACT FOR MASSIVE NB-IOT IN 5G WIRELESS NETWORKS
Jordanian Journal of Computers and Information Technology, 2021 To satisfy the gigantic need for Internet of things (IoT) applications, the third-generation partnership project (3GPP) has revealed the narrowband IoT (NB-IoT) standard. In any case, collisions in the radio access channel of NB-IoT can be extreme due to
