Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system

2011

Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…

Numerical construction of the density-potential mapping

2018

We demonstrate how a recently developed method Nielsen et al. [Nielsen et al., EPL 101, 33001 (2013)] allows for a comprehensive investigation of time-dependent density functionals in general, and of the exact time-dependent exchange-correlation potential in particular, by presenting the first exact results for two- and three-dimensional multi-electron systems. This method is an explicit realization of the Runge–Gross correspondence, which maps time-dependent densities to their respective potentials, and allows for the exact construction of desired density functionals. We present in detail the numerical requirements that makes this method efficient, stable and precise even for large and rap…

Television musiikkikykykilpailujen vaikutus nuoren käsitykseen muusikkoudesta : solistiset laulukilpailut, idolit ja julkisuus

2012

Nuorten kiinnostus television musiikkikykykilpailuja kohtaan on kasvanut räjähdysmäisesti viime vuosien aikana. Kandidaatin tutkielmassani tarkastelen tätä ilmiötä, ja kuinka nämä erilaiset musiikkikykyilpailut vaikuttavat nuoren käsitykseen muusikkoudesta. Median ja musiikkikykykilpailujen luomat idolit luovat tyylejä ja muokkaavat nuoren arvomaailmaa sekä kuvaa itsestä. Erilaiset musiikkikykykilpailut antavat kuitenkin usein melko yksipuolisen kuvan siitä, mitä muusikon ja artistin työ oikeasti on. Kandidaatin tutkielmassani tarkastelen erilaisia kilpailuja kriittisestä näkökulmasta, ja pohdin, minkä ikäisenä nuoren olisi hyvä lähteä kyseisiin kilpailuihin. Tärkeää on myös pohtia kuinka i…

isotracer: An R package for the analysis of tracer addition experiments

2022

Tracer addition experiments, particularly using isotopic tracers, are becoming increasingly important in a variety of studies aiming at characterizing the flows of molecules or nutrients at different levels of biological organization, from the cellular and tissue levels, to the organismal and ecosystem levels. However, performing rigorous statistical analyses to gain reliable quantitative insights from these experiments often remains challenging. We present an approach based on Hidden Markov Models (HMM) to estimate nutrient flow parameters across a network, and its implementation in the R package isotracer. The isotracer package is capable of handling a variety of tracer study designs, inc…

Negligible effect of hypolimnetic oxygenation on the trophic state of Lake Jyväsjärvi, Finland

2016

Hypolimnetic oxygenation by pumping oxygen-rich surface water to the hypolimnion (HLO) is a commonly used tool for the restoration of nutrient-loaded dimictic lakes. However, in recent years its effectiveness has been questioned. In this case study we evaluated monitoring data covering a period of 23-years to show that, although experimental cessation of HLO drastically changed the lake's temperature and dissolved oxygen regimes, it did not significantly affect its trophic status. Thus, we recommend that the limited financial resources available are better directed towards further lowering the lake's external phosphorus load than continuing HLO. peerReviewed

Muscle fiber-type distribution predicts weight gain and unfavourable left ventricular geometry: a 19 year follow-up study

2006

BACKGROUND: Skeletal muscle consists of type-I (slow-twitch) and type-II (fast-twitch) fibers, with proportions highly variable between individuals and mostly determined by genetic factors. Cross-sectional studies have associated low percentage of type-I fibers (type-I%) with many cardiovascular risk factors. METHODS: We investigated whether baseline type-I% predicts left ventricular (LV) structure and function at 19-year follow-up, and if so, which are the strongest mediating factors. At baseline in 1984 muscle fiber-type distribution (by actomyosin ATPase staining) was studied in 63 healthy men (aged 32–58 years). The follow-up in 2003 included echocardiography, measurement of obesity rel…

Il risarcimento sostituivo tra adempimento in natura e risoluzione del contratto

2019

The essay deals with the problem of the so called damages in lieu of the performance and its relations with the specific performance and the resolution. The author attempts to demonstrate that the issue of the damages in lieu of the performance is central to the debate on the priority of the specific performance and on the extent of compensation for damages from resolution.

Gaia-ESO Survey: H{alpha} emission stars catalogue

2015

We discuss the properties of H{alpha} emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely belonging to stars in young open clusters. Automated fits using two independent Gaussian profiles and a third component accounting for the nebular emission allow us to discern distinct morphological types of H{alpha} line profiles with the introduction of a simplified classification scheme. Altogether we find 3765 stars with intrinsic emission and sort their spectra into eight distinct morphological categories: single component emission, emission blend, sharp emission peaks, double emission, P-Cygni, inverted…

Spectra of high-mass X-ray binaries

2016

High-mass X-ray binaries are bright X-ray sources. The high-energy emission is caused by the accretion of matter from the massive companion onto a neutron star. The accreting material comes from either the strong stellar wind in binaries with supergiant companions or the circumstellar disk in Be/X-ray binaries. In either case, the H{alpha} line stands out as the main source of information about the state of the accreting material. We present the results of our monitoring program to study the long-term variability of the H{alpha} line in high-mass X-ray binaries. Our aim is to characterise the optical variability timescales and study the interaction between the neutron star and the accreting…
