Optimal channel switching in multiuser systems under average capacity constraints [PDF]
Digital Signal Processing, 2017 Abstract In this paper, the optimal channel switching problem is studied for average capacity maximization in the presence of multiple receivers in the communication system. First, the optimal channel switching problem is proposed for average capacity maximization of the communication between the transmitter and the secondary receiver while ...

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.

The Noncoherent Rician Fading Channel -- Part I : Structure of the Capacity-Achieving Input
, 2005 Transmission of information over a discrete-time memoryless Rician fading channel is considered where neither the receiver nor the transmitter knows the fading coefficients. First the structure of the capacity-achieving input signals is investigated when

On the average-listsize capacity and the cutoff rate of discrete memoryless channels with feedback [PDF]
2013 IEEE Information Theory Workshop (ITW), 2013 We study the cutoff rate and the average-listsize capacity of discrete memoryless channels (DMCs) with feedback. We show that feedback can increase the average-listsize capacity but not the cutoff rate. For DMCs with positive zero-error capacity, we show that the average-listsize capacity with feedback is equal to the cutoff rate.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Second-Order Asymptotics for the Classical Capacity of Image-Additive Quantum Channels
, 2015 We study non-asymptotic fundamental limits for transmitting classical information over memoryless quantum channels, i.e. we investigate the amount of classical information that can be transmitted when a quantum channel is used a finite number of times ...

Optimal channel switching for average capacity maximization in the presence of switching delays [PDF]
2016 IEEE Wireless Communications and Networking Conference, 2016 In this study, the optimal channel switching problem is investigated for average capacity maximization in the presence of channel switching delays. First, the optimal strategy is obtained and the corresponding average capacity is derived when channel switching is performed among a given number of channels.
