Neutriinojen sekoitusmatriisin Majorana-vaiheet

2013

Lukuisat hiukkasfysiikan kokeet ovat vahvistaneet neutriinojen olevan massallisia hiukkasia ja kykenevän muuttumaan neutriinotyypistä toiseen. Tätä niin kutsuttua neutriino-oskillaatiota parametrisoi neutriinojen sekoitusmatriisi, jota puolestaan parametrisoi kolmen sekoituskulman lisäksi yksi tai kolme CP-symmetriaa rikkovaa vaihetta riippuen siitä ovatko neutriinot Dirac- tai Majorana-hiukkasia. Tässä työssä tarkasteltiin edellä mainittujen Dirac- ja Majorana-vaiheiden merkitystä neutriino-oskillaatioissa, neutriinonottomassa kaksoisbeetahajoamisessa, Higgsin triplettimallissa ja baryoniepäsymmetrian synnyttäneessä leptonigeneesissä. Neutriino-oskillaation tarkastelua varten johdettiin ne…

Mid-regional pro-adrenomedullin predicts poor outcome in non-selected patients admitted to an intensive care unit.

2018

AbstractBackgroundMortality risk and outcome in critically ill patients can be predicted by scoring systems, such as APACHE and SAPS. The identification of prognostic biomarkers, simple to measure upon admission to an intensive care unit (ICU) is an open issue. The aim of this observational study was to assess the prognostic value of plasma mid-regional pro-adrenomedullin (MR-proADM) at ICU admission in non-selected patients in comparison to Acute Physiology and Chronic Health Evaluation II (APACHEII) and Simplified Acute Physiology Score II (SAPSII) scores.MethodsAPACHEII and SAPSII scores were calculated after 24 h from ICU admission. Plasma MR-proADM levels were measured by TRACE-Kryptor…

The Development of Motivation and Amotivation to Study and Work across Age-Graded Transitions in Adolescence and Young Adulthood

2019

People’s motivation to engage in studying and working is an important precursor of participation and attainment. However, little is known about how motivation and the lack of motivation develops normatively across adolescence and young adulthood. Furthermore, there is no comparison of motivation and amotivation development across sequential age-graded transitions such as the mid-schooling transition in adolescence and the school-to-work transition in young adulthood. The current study explored trajectories of motivation and amotivation development in Finland, using piecewise growth curve modelling to analyze five waves of data (age 15–22 years) from a sample of 878 youth (52% male). Indicat…

Beneficial effects of choir singing on cognition and well-being of older adults: Evidence from a cross-sectional study.

2021

Background and objectivesChoir singing has been associated with better mood and quality of life (QOL) in healthy older adults, but little is known about its potential cognitive benefits in aging. In this study, our aim was to compare the subjective (self-reported) and objective (test-based) cognitive functioning of senior choir singers and matched control subjects, coupled with assessment of mood, QOL, and social functioning.Research design and methodsWe performed a cross-sectional questionnaire study in 162 healthy older (age ≥ 60 years) adults (106 choir singers, 56 controls), including measures of cognition, mood, social engagement, QOL, and role of music in daily life. The choir singers…

Hidden sources of joy, fear, and sadness: Explicit versus implicit neural processing of musical emotions.

2016

Music is often used to regulate emotions and mood. Typically, music conveys and induces emotions even when one does not attend to them. Studies on the neural substrates of musical emotions have, however, only examined brain activity when subjects have focused on the emotional content of the music. Here we address with functional magnetic resonance imaging (fMRI) the neural processing of happy, sad, and fearful music with a paradigm in which 56 subjects were instructed to either classify the emotions (explicit condition) or pay attention to the number of instruments playing (implicit condition) in 4-s music clips. In the implicit vs. explicit condition, stimuli activated bilaterally the infe…

Memory-Based Mismatch Response to Frequency Changes in Rats

2011

Any occasional changes in the acoustic environment are of potential importance for survival. In humans, the preattentive detection of such changes generates the mismatch negativity (MMN) component of event-related brain potentials. MMN is elicited to rare changes (‘deviants’) in a series of otherwise regularly repeating stimuli (‘standards’). Deviant stimuli are detected on the basis of a neural comparison process between the input from the current stimulus and the sensory memory trace of the standard stimuli. It is, however, unclear to what extent animals show a similar comparison process in response to auditory changes. To resolve this issue, epidural potentials were recorded above the pr…
