Application of ZigZag Decoding in Frameless ALOHA

IEEE Access, 2019
As ZigZag decoding (ZD) can resolve a collision between two packets, the combination of ZD and successive interference cancellation (SIC) is expected to provide a lower packet loss rate (PLR) and higher average throughput than the conventional frameless ...

An Ultra‐Fast Rolling Double‐Helical Robot Driven by Constant Humidity

Advanced Science, EarlyView.
A double‐helical robot named Dualicalbot is proposed to achieve a high‐speed rolling under a constant humidity. The special asymmetric structural design makes sure that the two helices alternately drive the robot to roll with a remarkable speed of 5.8 BL s−1, 4.8 times faster than the fastest robot driven by a constant environment and surpassing the ...

Blind Adaptive Successive Interference Cancellation for Multicarrier DS-CDMA [PDF]

arXiv, 2011
A new adaptive receiver design for the Multicarrier (MC) DS-CDMA is proposed employing successive interference cancellation (SIC) architecture. One of the main problems limiting the performance of SIC in MC DS-CDMA is the imperfect estimation of multiple access interference (MAI), and hence, the limited frequency diversity gain achieved in multipath ...

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

Advanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

Finite Length Performance of Random Slotted ALOHA Strategies [PDF]

arXiv, 2016
Multiple connected devices sharing common wireless resources might create interference if they access the channel simultaneously. Medium access control (MAC) protocols gener- ally regulate the access of the devices to the shared channel to limit signal interference.

The Architecture of Large Kurgans of the Scythians and Their Periphery: A Challenge for Magnetometer Prospections in the Eurasian Steppe Belt

Archaeological Prospection, EarlyView.
ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.
