5G 3GPP-like Channel Models for Outdoor Urban Microcellular and Macrocellular Environments [PDF]

, 2016
For the development of new 5G systems to operate in bands up to 100 GHz, there is a need for accurate radio propagation models at these bands that currently are not addressed by existing channel models developed for bands below 6 GHz.

Wireless Link Capacity under Shadowing and Fading [PDF]

Proceedings of the 18th ACM International Symposium on Mobile Ad Hoc Networking and Computing, 2017
We consider the following basic link capacity (a.k.a., one-shot scheduling) problem in wireless networks: Given a set of communication links, find a maximum subset of links that can successfully transmit simultaneously. Good performance guarantees are known only for deterministic models, such as the physical model with geometric (log-distance) pathloss.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Robust multiple frequency multiple power localization schemes in the presence of multiple jamming attacks. [PDF]

PLoS ONE, 2017
Localization of the wireless sensor network is a vital area acquiring an impressive research concern and called upon to expand more with the rising of its applications. As localization is gaining prominence in wireless sensor network, it is vulnerable to

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Universal Kriging for Accurate Shadow Fading Modeling in LOS/NLOS Conditions

IEEE Open Journal of Antennas and Propagation
Traditional path loss (PL) models often fail to capture the spatial characteristics of wireless channels in environments combining line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, where shadow fading exhibits clear spatial non-stationarity ...

A Soft Computing Approach to Dynamic Load Balancing in 3GPP LTE [PDF]

, 2012
A major objective of the 3GPP LTE standard is the provision of high-speed data services. These services must be guaranteed under varying radio propagation conditions, to stochastically distributed mobile users.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Stochastic Ordering based Carrier-to-Interference Ratio Analysis for the Shotgun Cellular Systems

, 2011
A simple analytical tool based on stochastic ordering is developed to compare the distributions of carrier-to-interference ratio at the mobile station of two cellular systems where the base stations are distributed randomly according to certain non ...
