Enhanced PAPR reduction in NOMA systems using modified SLM and PTS techniques for power-efficient 5G and beyond networks

open access: yesOpen Engineering
This paper presents an enhanced framework for peak-to-average power ratio (PAPR) reduction in non-orthogonal multiple access (NOMA) systems using modified Selective Mapping (m-SLM) and Partial Transmit Sequence (m-PTS) algorithms.

Orbital angular momentum multiplexing architecture for OAM/SDM passive optical networks

open access: yesJournal of the European Optical Society-Rapid Publications
Orbital Angular Momentum (OAM) multiplexing is a technology of communication systems that enables high-capacity optical communication networks. One of the most important determinants of this technology is the channel capacity, loss of power, and Bit ...

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Virocell Necromass Provides Limited Plant Nitrogen and Elicits Rhizosphere Metabolites That Affect Phage Dynamics

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Evaluating tools for predicting and measuring radiometric performance of germicidal ultraviolet systems

open access: yesPhotochemistry and Photobiology, EarlyView.
An evaluation of simulation and measurement tools for germicidal ultraviolet (GUV) systems is presented to inform their design and deployment to control the spread of airborne pathogens. Abstract Germicidal ultraviolet (GUV) air treatment technologies can be effective and safe for reducing airborne disease transmission.

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

open access: yesPlant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Play in Cognitive Development: From Rational Constructivism to Predictive Processing

open access: yesTopics in Cognitive Science, EarlyView.
Abstract It is widely believed that play and curiosity are key ingredients as children develop models of the world. There is also an emerging consensus that children are Bayesian learners who combine their structured prior beliefs with estimations of the likelihood of new evidence to infer the most probable model of the world.
