Comparative analysis of intelligent reflecting surfaces and AF/DF relaying for energy efficient wireless communication

EURASIP Journal on Wireless Communications and Networking
This paper presents a comparative analysis of intelligent reflecting surface (IRS) technology versus conventional amplify-and-forward (AF) and decode-and-forward (DF) relay schemes in wireless communication.

On the error exponent of amplify and forward relay networks

, 2011
In this letter we derive the exact random coding error exponent of a dual hop amplify and forward (AF) relay network with channel state information (CSI) assisted ideal relay gain.

Xanthene‐Based FLPs Featuring Perchloroarylborane Substitutents: Interplay of Noncovalent Aggregation and Dihydrogen Activation

Chemistry – A European Journal, EarlyView.
Frustrated Lewis Pairs featuring perchloroarylborane Lewis acid groups are found to display unprecedented H2 uptake as a function of temperature, resulting from the thermodynamic balance between H─H cleavage and noncovalent intermolecular aggregation.

Harnessing machine learning and optimization for informed chemical engineering decisions: A styrene reactor analysis

The Canadian Journal of Chemical Engineering, EarlyView.
This study shows that integrating multiple machine learning models with optimization and decision‐making improves chemical process design, and that a consensus‐based strategy across models provides more robust and reliable operating recommendations than any single model, especially under limited or noisy data conditions.

Differential Associations Between ESG Performance, Firm Value, and Profitability: Evidence From S&P 500 Companies in Energy and Energy‐Related Sectors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Amid the growing prominence of sustainability considerations in financial decision‐making, the question of how environmental, social, and governance (ESG) performance translates into measurable financial outcomes has become particularly salient for industries exposed to intense regulatory pressure and environmental scrutiny, such as the energy

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

Developmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...

Energy Efficiency Contours for Amplify-and-Forward and Decode-and-Forward Cooperative Protocols

, 2012
In this paper we compare the energy efficiency of different cooperative schemes by means of energy efficiency contours. We consider a three-nodes cooperative scenario, employing either the amplify-and-forward (AF) or the decode-and-forward (DF) protocol.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Securing Water in a Changing Climate: A Transient Solar Desalination Model for the Sundarbans, Bangladesh

Energy Science &Engineering, EarlyView.
This graphical abstract presents a solar‐powered reverse osmosis (RO) system for the Sundarbans, Bangladesh. Mechanistic modeling reveals a critical seasonal mismatch: during the monsoon, feed water salinity peaks (24.8 ppt) while solar irradiance drops significantly.
