BART: The Czech Autonomous Observatory
2010
The High Energy Astrophysics group of the stellar department of the Astronomical Institute in Ondřejov operates two small aperture robotic telescopes called BART and D50. Both telescopes are capable of making automatic followup observation of gamma-ray burst optical counterparts. This paper deals with the smaller telescope BART.

Ab initio determination of the ionization potentials of DNA and RNA nucleobases
2006
Quantum chemical high level ab initio coupled-cluster and multiconfigurational perturbation methods have been used to compute vertical and adiabatic ionization potentials of the five canonical DNA and RNA nucleobases: uracil, thymine, cytosine, adenine, and guanine. Several states of their cations have been also calculated. The present results represent a systematic compendium of these magnitudes, establishing theoretical reference values at a level not reported before, calibrating computational strategies, and guiding the assignment of the features in the experimental photoelectron spectra.

Complete Genome Sequence of “Candidatus Portiera aleyrodidarum” BT-QVLC, an Obligate Symbiont That Supplies Amino Acids and Carotenoids to Bemisia ta…
2012
ABSTRACT The genome of “ Candidatus Portiera aleyrodidarum,” the primary endosymbiont of the whitefly Bemisia tabaci (Mediterranean species), is reported. It presents a reduced genome (357 kb) encoding the capability to synthetize, or participate in the synthesis of, several amino acids and carotenoids, being the first insect endosymbiont capable of supplying carotenoids.
Manipulating mtDNA in vivo reprograms metabolism via novel response mechanisms.
2019
Mitochondria have been increasingly recognized as a central regulatory nexus for multiple metabolic pathways, in addition to ATP production via oxidative phosphorylation (OXPHOS). Here we show that inducing mitochondrial DNA (mtDNA) stress in Drosophila using a mitochondrially-targeted Type I restriction endonuclease (mtEcoBI) results in unexpected metabolic reprogramming in adult flies, distinct from effects on OXPHOS. Carbohydrate utilization was repressed, with catabolism shifted towards lipid oxidation, accompanied by elevated serine synthesis. Cleavage and translocation, the two modes of mtEcoBI action, repressed carbohydrate rmetabolism via two different mechanisms. DNA cleavage activ…
FRIPON: a worldwide network to track incoming meteoroids
2020
Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important limiting factor as the most fragile - hence precious - meteorites must be recovered rapidly to avoid their alteration. Aims. The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receiver…
Bodily Flashes of Dancing Women: Dance as a Method of Inquiry
2003
In May 1997 I was in Nicaragua researching a dance ritual known as May Pole. The act of dancing itself became a method of inquiry in my research process. This article concentrates on the interaction of two dancing women, Evelyn and me. My dance experience has acquired different interpretations in relation to time and context as I have reflected on it. I also enrich this experience with other dance experiences to explore my dancing body in its different forms. This hermeneutical starting point creates the conditions for trusting my instrument, my body, as a source of bodily knowledge.
An English teacher's ways of motivating students in Dangerous Minds and Dead Poets Society
2014
Pedagogiikassa ja kielenopetuksen tutkimuksessa on jo vuosia painotettu motivaation merkitystä sekä oppilaille että opettajille ja motivaation vaikutusta oppimiseen. Motivaatiota on tutkittu laajasti ja monipuolisesti samoin kuin vaikuttavia tekijöitä oppilasmotivaatiossa, mutta englannin opettajan keinoja motivoida oppilaita ei ole tarkasteltu samalla aktiivisuudella. Täydentääkseen tätä tutkimuskenttää tämä tutkielma tutkii nimenomaan englannin opettajien keinoja motivoida oppilaita esitettynä elokuvissa Dangerous Minds sekä Dead Poets Society. Tutkimus keskustelee myös siitä, voidaanko näitä keinoja soveltaa käytännön opetustyöhön ja kuinka hyvin nämä keinot vastaavat motivoivan opetukse…
Maternal body mass index, gestational weight gain, and the risk of overweight and obesity across childhood: An individual participant data meta-analy…
2019
Background Maternal obesity and excessive gestational weight gain may have persistent effects on offspring fat development. However, it remains unclear whether these effects differ by severity of obesity, and whether these effects are restricted to the extremes of maternal body mass index (BMI) and gestational weight gain. We aimed to assess the separate and combined associations of maternal BMI and gestational weight gain with the risk of overweight/obesity throughout childhood, and their population impact. Methods and findings We conducted an individual participant data meta-analysis of data from 162,129 mothers and their children from 37 pregnancy and birth cohort studies from Europe, No…
