Design and Optimization of Joint Iterative Detection and Decoding Receiver for Uplink Polar Coded SCMA System

open access: yesIEEE Access, 2018
SCMA and polar coding are possible candidates for 5G systems. In this paper, we firstly propose the joint iterative detection and decoding (JIDD) receiver for the uplink polar coded sparse code multiple access (PC-SCMA) system.

Implementation of the Polar Code: Functional Requirements Regulating Ship Operations in Polar Waters

open access: yesArctic Review on Law and Politics, 2020
In 2017, the The International Code for Ships Operating in Polar Waters (Polar Code) – a set of function-based regulations applicable to Arctic and Antarctic waters, with the goal of increasing awareness and improving safety for ship operations in polar ...

Revisiting perceptions and evolving culture: a community dialogue on women in polar research [PDF]

open access: yes, 2018
Women have made outstanding contributions to polar research in recent decades, though full engagement may be hindered by persistent inequities, including notably the prevalence of workplace harassment.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Trichinella sp. in polar bears from Svalbard, in relation to hide length and age [PDF]

open access: yes, 2010
Diaphragm and masseter muscles from 376 polar bears ((irsur maririmus), 252 ringed seals (Phocn hispida), 84 bearded seals (Erignarhus barbarus), and 77 arctic foxes (Alopex lagopus) from Svalbard were examined for Trichinelln.

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

The interplay of global and polar regimes [PDF]

open access: yes, 1999
The growing salience of interactions between the functionally broad but geographically narrow regimes for the polar regions and the geographically broad but functionally specific regimes emerging to deal with global environmental changes directs ...

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Partially Information Coupled Polar Codes

open access: yesIEEE Access, 2018
We propose a new class of partially information coupled (PIC) polar codes to improve the transmission efficiency of transport block (TB)-based communication standards.
