Estimation of Aerosol Activation Ratio and Water Vapor Supersaturation at Cloud Base Using Aircraft Measurement

open access: yes应用气象学报, 2021
The vertical evolution of aerosol physiochemical properties significantly influence the capacity of particle water uptake at different atmospheric levels, which are important for the estimation of direct and indirect radiative impacts of aerosol. However,

Coupling Right- and Left-Handed Photons Differently to Charged Matter [PDF]

open access: yes, 2012
We consider a modification of electrodynamics in which right- and left-circularly polarized photons are coupled to charged sources differently. Even though photon helicity is a Lorentz invariant quantity, such a modification breaks Lorentz symmetry, as ...

Modifications of gravity [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009
General relativity (GR) is a phenomenologically successful theory that rests on firm foundations, but has not been tested on cosmological scales. The deep mystery of dark energy (and possibly even the requirement of cold dark matter (CDM)) has increased the need for testing modifications to GR, as the inference of such otherwise undetected

Time-scale and pitch modifications of speech signals and resynthesis from the discrete short-time Fourier transform [PDF]

open access: yes, 1996
The modification methods described in this paper combine characteristics of PSOLA-based methods and algorithms that resynthesize speech from its short-time Fourier magnitude only.

The siderophore-producing bacterium, Bacillus siamensis Gxun-6, has an antifungal activity against Fusarium oxysporum and promotes the growth of banana

open access: yesEgyptian Journal of Biological Pest Control, 2022
Background Fusarium wilt of banana is a soil-borne disease caused by Fusarium oxysporum formea speciales (f.sp.) cubense with the Tropical Race 4 (FOC TR4), which seriously restricts the development of the banana industry. The utilization of antagonistic
