New switching approach for DVR using one cycle control method

open access: yesAin Shams Engineering Journal, 2018
One of the effective devices to eliminate voltage disturbances of sensitive loads in distribution systems is dynamic voltage restorer (DVR). In previous studies, the sinusoidal pulse width modulation (SPWM) method has been used as a switching method for ...

Anharmonic Vibrational Eigenfunctions and Infrared Spectra from Semiclassical Molecular Dynamics [PDF]

open access: yes, 2018
We describe a new approach based on semiclassical molecular dynamics that allows to simulate infrared absorption or emission spectra of molecular systems with inclusion of anharmonic intensities.

Rescaling FSC curves

open access: yesActa Crystallographica Section D, EarlyView.
Calculating and plotting FSC curves on a uniform scale in inverse cubic resolution (Å−3) has several useful features.Similarity between two periodic functions is commonly assessed by comparing their Fourier coefficients within resolution shells. In particular, this approach is widely used in both crystallography and cryo‐electron microscopy (cryoEM ...

In vivo PET quantification of the dopamine transporter in rat brain with [¹⁸F]LBT-999. [PDF]

open access: yes, 2013
INTRODUCTION: We examined whether [(18)F]LBT-999 ((E)-N-(4-fluorobut-2-enyl)2β-carbomethoxy-3β-(4'-tolyl)nortropane) is an efficient positron emission tomography (PET) tracer for the quantification of the dopamine transporter (DAT) in the healthy rat ...

Orchard Management Influences Predation of Halyomorpha halys Eggs

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

open access: yesJournal of Zoology, EarlyView.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Towards breaking the curse of dimensionality in (ro)vibrational computations of molecular systems with multiple large-amplitude motions

open access: yes, 2019
Methodological progress is reported in the challenging direction of a black-box-type variational solution of the (ro)vibrational Schr\"odinger equation applicable to floppy, polyatomic systems with multiple large-amplitude motions.

Integrating virtual reality experiences with preservice and inservice science teachers

open access: yesSchool Science and Mathematics, EarlyView.
Abstract VR environments offer opportunities for novel science learning experiences. This article discusses how we integrated virtual reality experiences with preservice and inservice science teachers. We explore the affordances of VR for enhancing science education and its potential applications in secondary level classrooms. Specifically, we describe
