PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Multiple resource multiple access algorithms

IEEE Transactions on Communications, 1995
Two distributed multiple resource/multiple access algorithms, the receiver oriented protocol (ROP) and the dependent receiver oriented protocol (DROP), that are applicable to mobile networks connected by point-to-point radio or satellite links are presented and the maximum throughput is determined.

Channel-hopping multiple access

2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2000
The medium-access control (MAC) protocols for wireless networks proposed or implemented to date based on collision-avoidance handshakes between the sender and receiver either require carrier sensing or the assignment of unique codes to nodes to ensure that intended receivers hear data packets without interference from hidden sources.

Pattern Division Multiple Access: A New Multiple Access Technology for 5G

IEEE Wireless Communications, 2018
The anticipated 1000-fold increase in mobile data traffic over the next decade and the explosion of new services and applications pose great challenges for the current orthogonal multiple access (OMA)-based 4G systems. A promising solution to address these challenges is to shift from the currently predominant OMA to non-orthogonal multiple access (NOMA)

A “Group-Division Multiple Access” framework for channel access to multiple destinations

Ad Hoc Networks, 2008
We consider the problem of media-access control in multiple-cell networks, such as ad hoc networks in which clusterheads take on a role similar to base stations. We assume that a single channel is used by all cells, and that the user populations that transmit to different base stations overlap, causing interference in the neighboring cells.

Cognitive access algorithms for multiple access channels

2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013
This paper considers a multiple access fading channel where each terminal has a different belief about the channel states and adapts its transmission policy to the belief. In this setting, frequency division multiple access (FDMA) and channel aware random access (RA) are two special cases.

Multiple access communications networks

IEEE Communications Magazine, 1987
An introduction is provided to multiple-access communications networks in which the terminals share common communications channels. These networks include satellite networks, local area networks, and packet radio networks. Various multiple-access protocols are described, and it is shown how some of them are used in different multiple-access networks.

Noise-Loop Multiple Access

IEEE Transactions on Vehicular Technology, 2016
A fundamental problem for signal processing in wireless communications is the separation of multiple signals/users from their mixture. The problem is simpler if they are nonoverlapping in either the time domain or the frequency domain. Two signals may be overlapping in both time and frequency, but they can still be easily separated if they are ...

Coding for a multiple-access channel

IEEE Transactions on Information Theory, 1976
Summary: In this paper, coding for a multiple-access discrete memoryless channel is investigated. Some bounds on the rate pairs of uniquely decodable code pairs are derived. Coding procedures based on the Reed-Muller codes and their cosets are described for the noiseless case and for correction of single errors.
