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…
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…
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…
