Network-Coded Multigeneration Protocols in Heterogeneous Cellular Networks [PDF]
, 2018 In the upcoming era of 5G, the number of devices will increase massively, defining a heterogeneous wireless network. Nodes will be gathered in Mobile Clouds, and communicate between peers to achieve a general benefit. To provide packet resilience, error correction codes will be used. In particular, Random Linear Network Coding is standing out as one of

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Secrecy Outage Analysis for Distributed Antenna Systems in Heterogeneous Cellular Networks
IEEE Access, 2018 In this paper, we study physical-layer security for a spectrum-sharing heterogeneous cellular network consisting of a macro cell and an underlaying small cell, where a small base station (SBS) and a macro base station (MBS) transmit to their respective ...

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Bounds on the coverage probability of heterogeneous cellular networks [PDF]
2016 IEEE International Conference on Communications Workshops (ICC), 2016 In a heterogeneous cellular network (HCN), multiple tiers are employed to improve the network coverage probability. For this purpose, different properties of the coverage probability of an HCN should be studied carefully. This paper is classified into two main parts. First, a tight upper bound for the coverage probability of an HCN is derived.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Interference Management in Ultra-Dense 5G Networks With Excessive Drone Usage
IEEE Access, 2020 In fifth generation (5G) networks, the densification of small base stations in the coverage region of macro base station (MBS) leads to significant inter-cell interference (ICI). Similarly, drones (a.k.a. unmanned aerial vehicles) have a diverse scope in

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

A Novel Tractable Framework to Analyse Heterogeneous Cellular Networks
, 2016 Heterogeneous cellular networks consisting of microcell, picocell, femtocell, distributed antennas and relays co-deployed in space and frequency with carefully planned tower-mounted base stations, increase the complexity of the cellular network structure,

IEEE Access, 2017 We investigate the problem of multichannel allocation for small-cell users (SUs) in 5G heterogeneous cellular networks by taking users’ quality of experience (QoE) into account. In most existing channel allocation approaches, they are assumed that
