Published in 2018 at "Ecology and Evolution"

DOI: 10.1002/ece3.4229

Abstract: Abstract Extensive studies have focused on assessing leaf chlorophyll content through spectral indices; however, the accuracy is weakened by limited wavebands and coarse resolution. With hundreds of wavebands, hyperspectral data can substantially capture the essential… read more here.

Published in 2017 at "Journal of Raman Spectroscopy"

DOI: 10.1002/jrs.5087

Abstract: Here, we report, for the first time, on the first-order Raman spectra of the layered Mo-based ternaries: MoAlB, Mo2Ga2C and Mo2GaC. Polycrystalline samples were fabricated, and well-defined Raman spectra were recorded. When the experimental peak… read more here.

Published in 2017 at "Mathematical Methods in The Applied Sciences"

DOI: 10.1002/mma.3981

Abstract: This paper presents the existence of positive periodic solutions for first-order neutral differential equation with distributed deviating arguments. We apply Krasnoselskii's fixed point theorem to obtain our results. An example is given to support the… read more here.

Published in 2017 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.26315

Abstract: To develop a gradient pre‐emphasis scheme that prospectively counteracts the effects of the first‐order concomitant fields for any arbitrary gradient waveform played on asymmetric gradient systems, and to demonstrate the effectiveness of this approach using… read more here.

Published in 2018 at "Journal of High Energy Physics"

DOI: 10.1007/jhep02(2018)115

Abstract: A bstractThe nature of electroweak (EW) phase transition (PT) is of great importance. It may give a clue to the origin of baryon asymmetry if EWPT is strong first order. Although it is a cross… read more here.

Published in 2017 at "Journal of High Energy Physics"

DOI: 10.1007/jhep03(2018)017

Abstract: A bstractProper understanding of the geometry on the boundary of a spacetime is a critical step on the way to extending holography to spaces with non-AdS asymptotics. In general the boundary cannot be described in… read more here.

DOI: 10.1007/jhep06(2020)138

Abstract: The Wilsonian renormalization group (RG) properties of the conformal factor of the metric are profoundly altered by the fact that it has a wrong-sign kinetic term. The result is a novel perturbative continuum limit for… read more here.

Published in 2021 at "Journal of High Energy Physics"

DOI: 10.1007/jhep10(2021)193

Abstract: Abstract We show how the generation of right-handed neutrino masses in Majoron models may be associated with a first-order phase transition and accompanied by the production of a stochastic background of gravitational waves (GWs). We… read more here.
