Polar Code Appropriateness for Ultra-Reliable and Low-Latency Use Cases of 5G Systems

open access: yesInternational Journal of Networked and Distributed Computing (IJNDC)
Polar code is considered as a major breakthrough of past decade in channel coding area. The unprecedented performance of polar codes compelled third generation partnership project (3GPP) to adopt the polar codes for control channels functions in one of ...

Bit-Permuted Coded Modulation for Polar Codes [PDF]

open access: yes2017 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2017
We consider the problem of using polar codes with higher order modulation over AWGN channels. Unlike prior work, we focus on using modulation independent polar codes. That is, the polar codes are not re-designed based on the modulation used. Instead, we propose bit-permuted coded modulation (BPCM): a technique for using the multilevel coding (MLC ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Polar bears observed climbing steep slopes to graze on scurvy grass in Svalbard

open access: yes, 2017
It is well known that polar bears feed on vegetation. Here, I report novel observations of polar bears grazing on polar scurvy grass (Cochlearia groenlandica) at the foot of a large seabird colony on a cliff on Spitsbergen, Svalbard, in the summers of ...

On ice but not broken: Norwegian–Russian relations in polar science since 24 February 2022

open access: yes
Western countries responded to the full-scale Russian attack on Ukraine on 24 February 2022 by imposing strong sanctions to isolate Russia. Norway has adhered to this policy, with exceptions for cooperation on border control, search and rescue, and ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Polar bear hunt strategies evaluated by a Leslie matrix population model

open access: yes, 2010
An APL program for a Leslie matrix population projection is developed and applied to analysis of a Canadian polar bear population. Hunting specified with respect to sex ratio within a total quota may be included in the projections.

Polar Code Design for Irregular Multidimensional Constellations

open access: yesIEEE Access, 2017
Polar codes, ever since their introduction, have been shown to be very effective for various wireless communication channels. This, together with their relatively low implementation complexity, has made them an attractive coding scheme for wireless ...
