Olfactory responses of the predatory mite Phytoseiulus persimilis (Acari: Phytoseiidae) to rose leaves: starvation and previous host plant experience

open access: yesPersian Journal of Acarology, 2014
The effect of host plant experience and different hunger periods on the olfactory response of Phytoseiulus persimilis was studied on rose leaves under laboratory conditions. When clean air was considered as the olfactometer fixed arm, P.

Stochastic Volatility of Volatility in Continuous Time

open access: yesSSRN Electronic Journal, 2009
This paper introduces the concept of stochastic volatility of volatility in continuous time and, hence, extends standard stochastic volatility (SV) models to allow for an additional source of randomness associated with greater variability in the data.

Screening and characterization of biocontrol bacteria isolated from Ageratum conyzoides against Collectotrichum fructicola causing Chinese plum (Prunus salicina Lindl.) anthracnose

open access: yesFrontiers in Microbiology, 2023
Chinese plum (Prunus salicina Lindl.) is a nutritionally and economically important stone fruit widely grown around the world. Anthracnose, caused by Collectotrichum spp., is one of the primary biotic stress factors limiting plum production.

A simple joint model for returns, volatility and volatility of volatility

open access: yesJournal of Econometrics, 2023
We propose a model that allows for conditional heteroskedasticity in the volatility of asset returns and incorporates current return information into the volatility nowcast and forecast. Our model can capture all stylised facts of asset returns even with Gaussian innovations and is simple to implement.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Efficient degradation of sulfamethoxazole using unactivated and biochar-activated peroxymonosulfate: Mechanisms and performance comparison

open access: yesWater Cycle
Peroxymonosulfate (PMS)-based advanced oxidation processes are widely used in environmental purification. But the intrinsic oxidizing properties of unactivated PMS are often overlooked in pollutant degradation.

Influence of Plant Growth Retardants on Quality of Codonopsis Radix

open access: yesMolecules, 2017
Plant growth retardant (PGR) refers to organics that can inhibit the cell division of plant stem tip sub-apical meristem cells or primordial meristem cell. They are widely used in the cultivation of rhizomatous functional plants; such as Codonopsis Radix,
