Predictability decomposition detects the impairment of brain-heart dynamical networks during sleep disorders and their recovery with treatment
2016
This work introduces a framework to study the network formed by the autonomic component of heart rate variability (cardiac process η ) and the amplitude of the different electroencephalographic waves (brain processes δ , θ , α , σ , β ) during sleep. The framework exploits multivariate linear models to decompose the predictability of any given target process into measures of self-, causal and interaction predictability reflecting respectively the information retained in the process and related to its physiological complexity, the information transferred from the other source processes, and the information modified during the transfer according to redundant or synergistic interaction betwee…
4-hydroxy-ONN-azoxybenzene
2000
The oxidation of 4-hydroxyazobenzene provided a mixture of two azoxy compounds, which were separated by column chromatography. The isomer with the higher melting point appeared to belong to the α (ONN) series, as determined by X-ray diffraction. The molecule, C12H10N2O2, is almost planar. The benzene rings are twisted by 11.7 (2) (substituted) and 4.1 (1)° (unsubstituted) with respect to the ONN plane. The molecules are connected to one another by strong O—H⋯O hydrogen bonds forming chains extended along [001], which are bound by much weaker C—H⋯O hydrogen bonds forming layers in the bc plane.
Processing and characterization of highly oriented fibres of biodegradable nanocomposites
2015
Abstract Biodegradable polymeric materials are becoming day by day ever more important in packaging, agriculture, single-use cutleries and other large consumer applications. The major part of those materials is used under the form of film, i.e. subjected to elongational flow, but the main problem is that they often offer poor mechanical properties. Adding nanofillers, like Multi Walled Carbon Nanotubes (MWCNTs) may solve this problem but only if there is a full control of their orientation inside the material. Aim of this work is to investigate the processing-properties-morphology relationships for a system prepared under elongation flow of MaterBi and commercial MWCNTs. The materials were …
Kuka pelkää ruotsinopetusta? Täydennyskoulutus tukee ruotsin oppimista ja opetusta alakoulussa
2017
Ruotsin kielen opetus siirtyi alkamaan 6. luokalta uuden perusopetuksen opetussuunnitelman myötä. Keskustelua ovat aiheuttaneet esimerkiksi tuntijako, opettajien kielitaito ja ruotsin opetuksen pedagogiikka alakoulussa. Artikkelissa käsitellään Aikuis- ja täydennyskoulutuspalvelut AIKOPAn järjestämää opettajien täydennyskoulutusta, jossa pyrittiin parantamaan ruotsia opettavien aineenhallintaa ja pedagogista osaamista. Tulokset olivat positiivisia, ja täydennyskoulutukselle on selkeästi tilausta jatkossakin. nonPeerReviewed
Ko atklāj Ķīnas Ceļa un jostas iniciatīvas investīcijas? Nestriktas kopas kvalitatīvā salīdzinošā analīze
2020
Maģistra darbā “Ko atklāj Ķīnas Ceļa un jostas iniciatīvas investīcijas? Nestriktas kopas kvalitatīvā salīdzinošā analīze” tika analizēts Ķīnas Ceļa un jostas iniciatīvas (BRI) investīciju daudzums 78. Eirāzijas valstīs, lai noteiktu, kādi valstis raksturojoši faktori vai apstākļi ietekmē to vēlmi pievienoties BRI. Izvēlētajām valstīm pēc detalizētas pētnieciskās literatūras analīzes tika noteikti astoņi investīcijas veicinošie faktori (gan politiskie, gan ekonomiskie). Izvēlētie faktori tika pretnostatīti Ķīnas BRI investīciju apjomam uz vienu iedzīvotāju konkrētā valstī, lai varētu secināt, kādi valsti raksturojoši apstākļi un priekšnoteikumi veicina Ķīnas BRI investīciju plūsmu uz konkrē…
Backthrusts and passive roof duplexes in fold-and-thrust belts. The case of Central-Western Sicily based on seismic reflection data
2012
Seismic reflection profiles crossing the area bounded by the M. Kumeta Ridge and the M. Maranfusa-M. Galiello-Rocca Busambra morphostructural feature (central-western Sicily) were used to constrain the deep structural setting of the Sicilian-Maghrebian fold-and-thrust belt (FTB). By integrating seismic, field and well data, we attempted to correlate outcropping and deep-seated contractional structures, shedding light on the internal geometries of the thrust system. Results of the new seismostratigraphic analysis presented in this paper reveal structural variations along the tectonic edifice. This suggests dividing the study area into two sectors: the western sector is characterized by forel…
Effects of mixed reality head-mounted glasses during 90 minutes of mental and manual tasks on cognitive and physiological functions
2018
Background We evaluated the effects of a mixed reality (MR) head-mounted deviceon some cognitiveand physiological functions during 90 min tasks in an attempt to determine their safety for workers. Methods A total of 12 volunteers performed 90-min intellectual and manual tasks with and without MR glasses. Balance, Stroop, and memory tests were conducted before, during and after these tasks. Heart rate and electromyographic activity of some muscles were recorded. A survey was used to determine subjective fatigue, pain, or discomfort. Results Balance, heart rate, rate of perceived exertion, memory, and attention were unaffected by wearing MR glasses. Electromyographic activity increased with …
Symmetry patterns in the (N, Delta) spectrum
2007
We revise the role played by symmetry in the study of the low-lying baryon spectrum and comment on the difficulties when trying to generalize the symmetry pattern to higher energy states. We show that for the $(N,\Delta)$ part such a generalization is plausible allowing the identification of spectral regularities and the prediction of until now non-identified resonances.
Unitary theory of the deuteron photodisintegration.
1989
The deuteron photodisintegration in the \ensuremath{\Delta}-resonance region is calculated within a unitary theory of the NN-N\ensuremath{\Delta}-\ensuremath{\pi}NN system coupled to the photon. The photoexcitation amplitude of the \ensuremath{\Delta} is deduced from the ${M}_{1+}$((3/2) pion photoproduction amplitude consistently with its background term and the \ensuremath{\pi}N interaction. The NN-N\ensuremath{\Delta} transition amplitude is obtained from the coupled equations for the NN-N\ensuremath{\Delta}-\ensuremath{\pi}NN system. The one-pion-exchange currents as well as the normal single-nucleon current are included. The polarization parameters are reproduced quantitatively, but th…
Petrogenetic evolution of metabasalts and metakomatiites of the lower Onverwacht Group, Barberton Greenstone Belt (South Africa)
2019
A well-preserved sequence, by Archean standards, of mantle-derived metabasalts and metakomatiites forms large parts of the lower Onverwacht Group of the Barberton Greenstone Belt (South Africa). To elucidate the origin of mafic and ultramafic rocks from this 3.55 to 3.45 Ga sequence, we present a comprehensive geochemical dataset including major and trace elements as well as Lu-Hf and Sm-Nd isotope compositions for a variety of metavolcanic rocks. These include metabasalts of the amphibolite-facies Sandspruit and Theespruit Formations as well as metabasalts and metakomatiites of the lower greenschist-facies Komati Formation. Based on their incompatible trace element patterns, the basalts of…
