Tekoäly reaaliaikaisissa strategiapeleissä
2015
Reaaliaikaisille strategiapeleille ovat ominaisia monimutkaiset dynaamiset ympäristöt, joissa ei ole täsmällistä tietoa ympäristöstä. Tällaiset ympäristöt ovat haastavia tekoälylle. Aihetta kannattaa kuitenkin tutkia, sillä ongelmien ratkonta genren peleissä auttaa myös useiden vastaavien tosielämän ongelmien ratkaisemisessa. Työn tavoitteena on luoda kattava yleiskuva reaaliaikaisten strategiapelien tekoälyn ja tekoälytutkimuksen tilaan painottaen teknisiä menetelmiä. Reaaliaikaisten strategiapelien monimutkaisuudesta johtuen näitä menetelmiä on runsaasti, ja käytännössä kaikki niistä kaipaavat lisätutkimusta. Complex dynamic environments with neither perfect nor complete information about…
Identification, characterization and analysis of expression of genes encoding arylalkylamine N-acetyltransferases in the pea aphidAcyrthosiphon pisum
2013
Most organisms exhibit some kind of rhythmicity in their behaviour and/or physiology as an adaptation to the cyclical movements of the Earth. In addition to circadian rhythms, many organisms have an annual rhythmicity in certain activities, such as reproduction, migration or induction of diapause. Current knowledge of the molecular basis controlling seasonal rhythmicity, especially in insects, is scarce. One element that seems to play an essential role in the maintenance of both circadian and seasonal rhythms in vertebrates is the hormone melatonin. In vertebrates, the limiting enzyme in its synthesis is the arylalkylamine N-acetyltransferase (AANAT). Melatonin is also present in insects bu…
Photoperiodic effects on diapause-associated gene expression trajectories in EuropeanLeptinotarsa decemlineatapopulations
2014
Behavioural and physiological changes during diapause, an important strategy of insects for surviving harsh seasonal conditions, have been intensively studied. The genetic and molecular mechanisms underpinning diapause development are less well known. We took a candidate gene approach to study prediapause gene expression patterns in the Colorado potato beetle (Leptinotarsa decemlineata), an invasive insect that has rapidly spread northwards to high seasonality environments. Newly eclosed beetles originating from southern (Italy) and northern (Russia) Europe were reared under short- [12 h light (L):12 h dark (D)] and long-day (18L:6D) photoperiods for 10 days. This time period includes the s…
Photoperiodic regulation of life-history traits before and after eclosion: egg-to-adult development time, juvenile body weight and reproductive diapa…
2012
Photoperiod is the main environmental cue used by northern insects to predict the forthcoming seasonal changes and to adjust their life-history traits to fit these changes. We studied the effects of photoperiod on egg-to-adult development time, juvenile body mass and female reproductive diapause in two northern Drosophila montana populations with different patterns of voltinism. The most interesting findings were consistent between the populations: (1) when maintained before eclosion in short day conditions, representing early autumn, the flies developed faster and were lighter than when maintained in long day conditions, representing early summer, (2) photoperiodic time measurement is appa…
Northern Drosophila montana flies show variation both within and between cline populations in the critical day length evoking reproductive diapause
2013
Reproductive diapause, and its correct timing, plays an important role in the life cycle of many insect species living in a seasonally varying environment at high latitudes. In the present paper we have documented variation in the critical day length (CDL) for adult reproductive diapause and the steepness of photoperiodic response curves (PPRCs) in seven clinal populations of Drosophila montana in Finland between the latitudes 61 and 67°N, paying special attention to variation in these traits within and between cline populations. The isofemale lines representing these populations showed a sharp transition from 0% to 100% in females' diapause incidence in the shortening day lengths, indicate…

The 18th-century traditions of representation in a new age of revolution : History politics in the Swedish and Finnish parliaments, 1917−1919
2014
What happened to shared historical experiences in the discursive processes of constitutional reform in Sweden and Finland? This article examines the use of 18th-century history in early 20th-century politics. Building on a long-term survey of Swedish and Finnish estate and parliamentary debates, it analyses the political implications of differing national historiographies in the two successor states of the 18th-century Swedish realm, focusing on how the ancient past and collective (and often selective) memories of the Age of Absolutism, the Age of Liberty and the Gustavian Age were used by parliamentarians in constitutional debates. The analysis demonstrates how the Finnish polity continued…
