Optimal Discrete Spatial Compression for Beamspace Massive MIMO Signals

, 2017
Deploying massive number of antennas at the base station side can boost the cellular system performance dramatically. Meanwhile, it however involves significant additional radio-frequency (RF) front-end complexity, hardware cost and power consumption. To

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Static and Dynamic Analysis of Cellular Beams

International Journal of Recent Technology and Engineering (IJRTE), 2019
Utilization of castellated beam has become extremely well known nowadays because of its beneficial auxiliary applications. The chief preferred position of castellated beam is increment in vertical twisting solidness, simplicity of administration arrangement and appealing appearance.

A FE parametric study of RWS beam-to-column bolted connections with cellular beams [PDF]

Journal of Constructional Steel Research, 2016
In recent years, researchers study alternative connection designs for steel seismic-resistant frames by reducing the beam section in different ways including that of creating an opening in its web (RWS connections). A similar design is applied in the fabrication of perforated (i.e.

An Efficient Uplink Multi-Connectivity Scheme for 5G mmWave Control Plane Applications

, 2017
The millimeter wave (mmWave) frequencies offer the potential of orders of magnitude increases in capacity for next-generation cellular systems. However, links in mmWave networks are susceptible to blockage and may suffer from rapid variations in quality.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Shear connection requirements for composite cellular beams

Proceedings 12th international conference on Advances in Steel-Concrete Composite Structures - ASCCS 2018, 2018
Beams with regular circular web openings (cellular beams) are often used in composite construction. Rules for the minimum degree of shear connection in composite beams are presented in Eurocode 4 but were derived for solid web beams in propped construction. This paper investigates the degree of shear connection requirements for composite cellular beams,
