Determinētu, nedeterminētu un varbūtisku automātu sarežģītības salīdzinājums ar ultrametriskiem automātiem
2015
Maģistra darbā "Determinētu, nedeterminētu un varbūtisku automātu sarežģītības salīdzinājums ar ultrametriskiem automātiem" tiek aprakstīti p-adiski skaitļi un to izmantošana vienvirziena p-ultrametriskos automātos. Darba gaitā tiek apskatītas vienvirziena p-ultrametrisku automātu iespējas atpazīt neregulāras valodas, kurām pielietotas unāras un bināras operācijas, un tiek salīdzināts stāvokļu skaita sarežģītības mērs viena burta alfabēta valodām vienvirziena determinētiem, divvirzienu determinētiem, vienvirziena nedeterminētiem, vienvirziena varbūtiskiem un vienvirziena p-ultrametriskiem galīgiem automātiem.
High-precision measurement of a low Q value for allowed β−-decay of 131I related to neutrino mass determination
2022
The ground-state-to-ground-state β−-decay 131I (7/2+) → 131Xe (3/2+) Q value was determined with high precision utilizing the double Penning trap mass spectrometer JYFLTRAP at the IGISOL facility. The Q value of this β−-decay was found to be Q = 972.25(19) keV through a cyclotron frequency ratio measurement with a relative precision of 1.6 × 10−9. This was realized using the phase-imaging ion-cyclotron-resonance technique. The new Q value is more than 3 times more precise and 2.3σ higher (1.45 keV) than the value extracted from the Atomic Mass Evaluation 2020. Our measurement confirms that the β−-decay to the 9/2+ excited state at 971.22(13) keV in 131Xe is energetically allowed with a Q va…
In vivo fascicle behavior of the flexor hallucis longus muscle at different walking speeds
2017
Ankle plantar flexor muscles support and propel the body in the stance phase of locomotion. Besides the triceps surae, flexor hallucis longus muscle (FHL) may also contribute to this role, but very few in vivo studies have examined FHL function during walking. Here, we investigated FHL fascicle behavior at different walking speeds. Ten healthy males walked overground at three different speeds while FHL fascicle length changes were recorded with ultrasound and muscle activity was recorded with surface electromyography (EMG). Fascicle length at heel strike at toe off and at peak EMG activity did not change with speed. Range of FHL fascicle length change (3.5-4.5 and 1.9-2.9 mm on average in s…
