Time-division duplex (TDD) based massive MIMO systems rely on the reciprocity of the wireless propagation channels when calculating the downlink precoders based on uplink pilots. However, the effective uplink and downlink channels incorporating the analog radio front-ends of the base station (BS) and user equipments (UEs) exhibit non-reciprocity due to non-identical behavior of the individual t...

We study the expressive power of the static type system of the Nested Relational Calculus NRC and show that on so-called homogeneous input and output types, the NRC type system is expressively complete: every untyped but homogeneously well-defined NRC expression can be equivalently expressed by a well-typed expression. The NRC static type system hence does not limit the expressive power of the ...

This study presents a conceptual framework for understanding firm's performance is impacted by the nomination and remuneration committee (NRC), risk management (RMC) moderating role of CEO power. The research sample will consist 68 non-financial public companies that were listed on Amman Stock Exchange between 2017 2020. Tobin's Q ROA also be used to assess firm performance. While NRC, RMC, pow...

Proteins from extremophiles have the ability to fold and remain stable in their extreme environment. Here, we investigate the presence of this effect in the cysteinyl-tRNA synthetase from Halobacterium salinarum ssp. NRC-1 (NRC-1), which was used as a model halophilic protein. The effects of salt on the structure and stability of NRC-1 and of E. coli CysRS were investigated through far-UV circu...

NRC-CISTI serves Canada as its National Science Library (as mandated by Canada’s Parliament in 1924) and also provides direct support to researchers of the National Research Council of Canada (NRC). By reason of its mandate, vision, and strategic positioning, NRC-CISTI has been rapidly and effectively mobilizing Canadian stakeholders and resources to become a lead player on both the Canadian na...

We previously reported the cloning and characterization of a novel nuclear hormone receptor transcriptional coactivator, which we refer to as NRC. NRC is a 2,063-amino-acid nuclear protein which contains a potent N-terminal activation domain and several C-terminal modules which interact with CBP and ligand-bound nuclear hormone receptors as well as c-Fos and c-Jun. In this study we sought to cl...

Introduction: The Martian north polar residual cap (NRC) lies on top of the north polar layered deposits (NPLD). The NRC is about 1m thick and composed primarily of large-grained, dust-poor water ice [1]. The mass balance of the polar cap is uncertain. Long-term monitoring reveals small reversible changes in its extent on an interannual basis [2]. Images with a pixel scale of up to 0.25 m/pixel...
