Resistance to bio-insecticides or how to enhance their sustainability: a review.

Frontiers in plant science

Siegwart M, Graillot B, Blachere Lopez C, Besse S, Bardin M, Nicot PC, Lopez-Ferber M.
PMID: 26150820
Front Plant Sci. 2015 Jun 19;6:381. doi: 10.3389/fpls.2015.00381. eCollection 2015.

After more than 70 years of chemical pesticide use, modern agriculture is increasingly using biological control products. Resistances to conventional insecticides are wide spread, while those to bio-insecticides have raised less attention, and resistance management is frequently neglected. However,...

Observation of antiferromagnetic domains in epitaxial thin films.

Science (New York, N.Y.)

Scholl A, Stohr J, Luning J, Seo JW, Fompeyrine J, Siegwart H, Locquet J, Nolting F, Anders S, Fullerton EE, Scheinfein MR, Padmore HA.
PMID: 10669407
Science. 2000 Feb 11;287(5455):1014-6. doi: 10.1126/science.287.5455.1014.

Antiferromagnetic domains in an epitaxial thin film, LaFeO(3) on SrTiO(3)(100), were observed using a high-spatial-resolution photoelectron emission microscope with contrast generated by the large x-ray magnetic linear dichroism effect at the multiplet-split L edge of Fe. The antiferromagnetic domains...

Direct observation of the alignment of ferromagnetic spins by antiferromagnetic spins.

Nature

Nolting F, Scholl A, Stohr J, Seo JW, Fompeyrine J, Siegwart H, Locquet JP, Anders S, Luning J, Fullerton EE, Toney MF, Scheinfein MR, Padmore HA.
PMID: 10866191
Nature. 2000 Jun 15;405(6788):767-9. doi: 10.1038/35015515.

The arrangement of spins at interfaces in a layered magnetic material often has an important effect on the properties of the material. One example of this is the directional coupling between the spins in an antiferromagnet and those in...

Properties of the photonic Hall effect in cold atomic clouds.

Physical review letters

Grémaud B, Delande D, Sigwarth O, Miniatura C.
PMID: 19519133
Phys Rev Lett. 2009 May 29;102(21):217401. doi: 10.1103/PhysRevLett.102.217401. Epub 2009 May 27.

On the basis of exact numerical simulations and analytical calculations, we describe qualitatively and quantitatively the interference processes at the origin of the photonic Hall effect for resonant Rayleigh (point-dipole) scatterers in a magnetic field. For resonant incoming light,...

Eating disorder diagnostics in the digital era: validation of the Norwegian version of the Eating Disorder Assessment for DSM-5 (EDA-5).

Journal of eating disorders

Dahlgren CL, Walsh BT, Vrabel K, Siegwarth C, Rø Ø.
PMID: 32670578
J Eat Disord. 2020 Jul 09;8:30. doi: 10.1186/s40337-020-00310-7. eCollection 2020.

OBJECTIVE: The Eating Disorder Assessment for DSM-5 (EDA-5) is an electronic, semi-structured interview developed to assess feeding and eating disorders following DSM-5 criteria. The original English version has strong psychometric properties, and previous research has shown high rates of...

The Working Memory Network and Its Association with Working Memory Performance in Survivors of non-CNS Childhood Cancer.

Developmental neuropsychology

Siegwart V, Steiner L, Pastore-Wapp M, Benzing V, Spitzhuttl J, Schmidt M, Kiefer C, Slavova N, Grotzer M, Roebers C, Steinlin M, Leibundgut K, Everts R.

Dev Neuropsychol. 2021 Apr-Jun;46(3):249-264. doi: 10.1080/87565641.2021.1922410.

Childhood cancer and its treatment puts survivors at risk of low working memory capacity. Working memory represents a core cognitive function, which is crucial in daily life and academic tasks. The aim of this functional MRI (fMRI) study was...

Fear and discomfort of children and adolescents during MRI: ethical consideration on research MRIs in children.

Estimated Uncertainty of Calculated Liquefied Natural Gas Density from a Comparison of NBS and Gaz de France Densimeter Test Facilities.

Journal of research of the National Bureau of Standards (1977)

Roncier M, Philippe R, Saint-Just J, Dewerdt F, Siegwarth JD, LaBrecque JF.
PMID: 34566101
J Res Natl Bur Stand (1977). 1983 May-Jun;88(3):163-170. doi: 10.6028/jres.088.009.

Liquefied natural gas (LNG) densities can be measured directly but are usually determined indirectly in custody transfer measurement by using a density correlation based on temperature and composition measurements. An LNG densimeter test facility at the National Bureau of...

Is the efficacy of biological control against plant diseases likely to be more durable than that of chemical pesticides?.

Frontiers in plant science

Bardin M, Ajouz S, Comby M, Lopez-Ferber M, Graillot B, Siegwart M, Nicot PC.
PMID: 26284088
Front Plant Sci. 2015 Jul 27;6:566. doi: 10.3389/fpls.2015.00566. eCollection 2015.

The durability of a control method for plant protection is defined as the persistence of its efficacy in space and time. It depends on (i) the selection pressure exerted by it on populations of plant pathogens and (ii) on...

Hanle effect in coherent backscattering.

Physical review letters

Labeyrie G, Miniatura C, Müller CA, Sigwarth O, Delande D, Kaiser R.

We study the shape of the coherent-backscattering (CBS) cone obtained when resonant light illuminates a thick cloud of laser-cooled rubidium atoms in the presence of a homogenous magnetic field. We observe new magnetic field-dependent anisotropies in the CBS signal....
