Signal Recognition Particle 54 kD Protein (SRP54) from the Marine Sponge Geodia cydonium
2002
In the systematic search for phylogenetically conserved proteins in the simplest and most ancient extant metazoan phylum – Porifera, we have identified and analyzed a cDNA encoding the signal recognition particle 54 kD protein (SRP54) from the marine sponge Geodia cydonium (Demospongiae). The signal recognition particle (SRP) is a universally conserved ribonucleoprotein complex of a very ancient origin, comprising SRP RNA and several proteins (six in mammals). The nucleotide sequence of the sponge cDNA predicts a protein of 499 amino acid residues with a calculated Mr of 55175. G. cydonium SRP54 displays unusually high overall similarity (90 %) with human/mammalian SRP54 proteins, higher th…
Search for inelastic scattering of WIMP dark matter in XENON1T
2021
We report the results of a search for the inelastic scattering of weakly interacting massive particles (WIMPs) in the XENON1T dark matter experiment. Scattering off $^{129}$Xe is the most sensitive probe of inelastic WIMP interactions, with a signature of a 39.6 keV de-excitation photon detected simultaneously with the nuclear recoil. Using an exposure of 0.89 tonne-years, we find no evidence of inelastic WIMP scattering with a significance of more than 2$\sigma$. A profile-likelihood ratio analysis is used to set upper limits on the cross-section of WIMP-nucleus interactions. We exclude new parameter space for WIMPs heavier than 100 GeV/c${}^2$, with the strongest upper limit of $3.3 \time…
XENON1T Dark Matter Data Analysis: Signal Reconstruction, Calibration and Event Selection
2019
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric $\mathrm{ton}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In pa…
How to apply privacy by design in osint and big data analytics?
2019
In a world where technology grows exponentially, more information is available to us every day. States and their governments have collected information on their citizens for a long time now. On the other hand, people give out more and more personal information voluntarily through social media. Information available on the Internet is easier to analyze with modern technologies and the original source of information is also easier to track down. Information is available to all of us and that information can be used to investigate personal data, defeat competitors in a corporate world, solve crimes or even win wars. This study analyses open source intelligence (OSINT) and big data analytics (B…
Korkeakoulutuksen eriytyvät työelämätulokset
2018
Tässä väitöskirjassa tarkastellaan korkeakoulutettujen tutkinnollaan saavuttamien työelämätulosten eriytymistä ja eriytymisen yhteyttä koulutusalaan sekä muihin tutkinnon suorittaneiden taustaan liittyviin tekijöihin. Näitä tekijöitä ovat sukupuoli, pohjakoulutus ja ikä. Lisäksi eriytymistä tarkastellaan työantajasektorin (julkinen/yksityinen) mukaan, joka on olennaisesti yhteydessä sekä koulutusalaan että sukupuoleen. Tutkimuksen teoreettisessa kehyksessä korkeakoulututkinto ymmärretään resurssina, joka valmistuneella on hyödynnettävissä työelämään sijoittumisessa, mutta jonka hyödynnettävyys eriytyy henkilöiden muiden ominaisuuksien mukaan. Resurssinäkökulma perustuu signaaliteoriaan, jon…

"On-the-go" multispectral imaging system embedded on a track laying tractor to characterize the vine foliage
2015
Mutispectral imaging systems are widely used in remote sensing for Precision Viticulture. In this work, this technique was applied in the proximal sensing context to characterize vine foliage. A mobile terrestrial experimental system is presented, composed of a GPS receiver, a multi-spectral camera acquiring visible and near infrared images, and a Greenseeker RT-100 which measures the Normalized Difference Vegetative Index (NDVI). This optical system observes vine foliage in the trellis plan, in natural sunlight. The experimental field is planted with Chardonnay, Pinot Noir and Meunier cultivars in a latin squared pattern. In 2013, six datasets were acquired at various phenological stages.S…
Hearing gestures : vocalisations as embodied projections of intentionality in designing non-speech sounds for communicative functions
2011
Experience design and writing for digital media. A scriptural theory of experience applied to instructional design and design pedagogy.
2020
Cet ouvrage pour l'HDR en sciences de l'information et de la communication propose une théorie de l'expérience des médias numériques pour l'aborder du point de vue de l'écriture numérique. Tandis que la sociologie des usages analyse la partie visible des interactions numériques sans intervenir sur elles, dans une perspective objectiviste, les études sur l'expérience, qui forment un champ récent dans les SHS, s'intéressent d'une part à la manière dont l'expérience des technologies numériques écrit en nous son histoire, tandis que nous laissons dans les machines des traces qui constituent à son leur une inscription, les deux types d'écriture étant indissociables. D'autre part, les études sur …
Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
