N-DCF: MAC overhead reduction using narrow channel contention in wireless networks
EURASIP Journal on Wireless Communications and Networking, 2018 This paper presents a medium access control protocol for wireless networks that improves system spectral efficiency using multiple channels. Use of multiple narrow channels has already been proposed as a solution to reduce MAC overhead, but merely ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Reduced Complexity Rate-Splitting Multiple Access Beamforming for Generalized Objectives
IEEE AccessRate splitting multiple access (RSMA) enables interference management trade-offs between space-division multiple access (SDMA) and non-orthogonal multiple access (NOMA) to serve multiple users in the multiple-input multiple-output (MIMO) broadcast ...

Coding for a multiple-access channel
Information and Control, 1978 The channel considered here is a real-number adder. Attention is restricted to the case of two sources using binary signals; hence the channel has a ternary output. The paper treats both the noiseless and noisy situations. For the noiseless case the following results are obtained: several code-construction techniques are presented; a Gilbert-like lower

Asynchronous multiple-access channel capacity [PDF]
IEEE Transactions on Information Theory, 1981 The capacity region for the discrete memoryless multiple-access channel without time synchronization at the transmitters and receivers is shown to be the same as the known capacity region for the ordinary multiple-access channel. The proof utilizes time sharing of two optimal codes for the ordinary multiple-access channel and uses maximum likelihood ...

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.

Channel-Aware Multichannel Random Access for Energy-Limited Sensors and MTC Devices
IEEE Access, 2018 In machine-type communications (MTC) or wireless sensor networks (WSNs), since MTC devices or sensors have limited supply of energy, energy efficient transmission schemes are important.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
