Energy-Efficient Design of IRS-NOMA Networks [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2020
Combining intelligent reflecting surface (IRS) and non-orthogonal multiple access (NOMA) is an effective solution to enhance communication coverage and energy efficiency.

Ergonomics in IR

Journal of Vascular and Interventional Radiology, 2021
Ergonomic research in the field of interventional radiology remains limited. Existing literature suggests that operators are at increased risk for work-related musculoskeletal disorders related to the use of lead garments and incomplete knowledge of ergonomic principles.

Modeling of Ir adatoms on Ir surfaces

Physical Review B, 1996
We used the embedded-atom method potential to study the structures, adsorption energies, binding energies, migration paths, and energy barriers of the Ir adatom and small clusters on fcc Ir (100), (110), and (111) surfaces. We found that the barrier for single-adatom diffusion is lowest on the (111) surface, higher on the (110) surface, and highest on ...

We Are IR

CardioVascular and Interventional Radiology, 2010
THE publication of the Global Statement Defining Interventional Radiology (IR) in this issue comes at a time of critical growth and immense challenges for our specialty (1). Imageguided interventions are now as integral to health care as diagnostic imaging.

Radiogenomics and IR

Journal of Vascular and Interventional Radiology, 2018
Radiogenomics involves the integration of mineable data from imaging phenotypes with genomic and clinical data to establish predictive models using machine learning. As a noninvasive surrogate for a tumor's in vivo genetic profile, radiogenomics may potentially provide data for patient treatment stratification.

From IR to Mobile IR

2017
This chapter highlights how Mobile Information Retrieval was born out of the mobile phone revolution and explains the similarities. After a very brief overview of Information Retrieval, it addresses the main differences between standard Information Retrieval and Mobile Information Retrieval.

IR polarimetry and far-IR imaging

SPIE Proceedings, 2004
The exploitation of infrared polarimetry has been shown to yield good results when applied to target discrimination in military applications and to civilian remote sensing problems. Similarly, numerous workers have shown that imaging sensors operating in the far infrared spectral bands may be useful in such counter-terror applications as concealed ...

Coopetition in IR Research

Proceedings of the 43rd International ACM SIGIR Conference on Research and Development in Information Retrieval, 2020
Coopetition is defined as competitors cooperating for the common good, an apt description of the community evaluations such as TREC that build infrastructure to support information retrieval (IR) research. This note summarizes the main points of a keynote talk presented at SIGIR 2020 that looks at the benefits and risks coopetition can engender in IR ...
