Hölder gradient regularity for the inhomogeneous normalized p(x)-Laplace equation
2022
We prove the local gradient Hölder regularity of viscosity solutions to the inhomogeneous normalized p(x)-Laplace equation −Δp(x)Nu=f(x), where p is Lipschitz continuous, infp>1, and f is continuous and bounded. peerReviewed
Hölder regularity for the gradient of the inhomogeneous parabolic normalized p-Laplacian
2018
In this paper, we study an evolution equation involving the normalized [Formula: see text]-Laplacian and a bounded continuous source term. The normalized [Formula: see text]-Laplacian is in non-divergence form and arises for example from stochastic tug-of-war games with noise. We prove local [Formula: see text] regularity for the spatial gradient of the viscosity solutions. The proof is based on an improvement of flatness and proceeds by iteration.
MODELING OF VOLATILITY IN THE ROMANIAN CAPITAL MARKET
2012
This paper aims to analyze the volatility of capital market in Romania by selecting a portfolio of representative indices (BET BET_FI and RASDAQ_C). In this respect, we want to identify the most appropriate model to estimate volatility by using modern econometric tools and useful GARCH models respectively. The study results highlight that EGARCH(1,1) model has managed to eliminate all traces of statistically significant autocorrelation and ARCH effects from the residuals from daily series, giving an accurate image of the Romanian capital market volatility.

Caracterización de la voz eufónica a partir de parámetros acústicos y electromiografía de superficie
2022
El objetivo de este estudio es describir de manera detallada las características de la voz eufónica o normal, a través de parámetros acústicos de corta duración y electromiográficos de superficie. Procedimiento: Los datos se obtuvieron de 146 sujetos de habla hispana (72 hombres y 74 mujeres) entre 20 y 50 años de edad sin alteración vocal, previo cálculo del tamaño de la muestra. Las muestras vocales fueron clasificadas audioperceptivamente como voces normales (G = 0) por 3 expertos en el área de la voz. Las diferentes muestras vocales se registraron y analizaron con el software de análisis acústico Praat (Boersma & Weenink, Ámsterdam, Países Bajos) y con electromiografía de superficie (EM…
Koulukiusaaminen ilmiönä : yläkoulun oppilaiden kokemuksia kiusaamisesta
2006
Hamaruksen mukaan kiusaaminen perustuu usein kiusaajan tavoittelemalle valta-asemalle yhteisössä ja alkaa jonkun oppilaan erilaisuuden nimeämisestä. Tästä piirteestä luodaan nimityksiä ja kiusatulle rakennetaan maine, joka tarttuu ja leviää yhteisössä tarinoiden kertomisen välityksellä. Tarinoiden kertominen, hauskat jutut ja kiusaamiseen liittyvät rituaalit yhdistävät kiusaamiseen osallistuvia ja vahvistavat kiusaajan asemaa yhteisössä. Kiusaaminen jakaa yhteisön jäsenet ”meihin” ja ”heihin”.Kiusaaminen koostuu hetkellisistä vuorovaikutustilanteista, joiden havaitseminen ja tunnistaminen kiusaamiseksi voi olla ulkopuoliselle vaikeaa. Asiat, joista kiusataan, liittyvät oppilaskulttuurissa h…

H&E Multi-Laboratory Staining Variance Exploration with Machine Learning
2022
In diagnostic histopathology, hematoxylin and eosin (H&E) staining is a critical process that highlights salient histological features. Staining results vary between laboratories regardless of the histopathological task, although the method does not change. This variance can impair the accuracy of algorithms and histopathologists’ time-to-insight. Investigating this variance can help calibrate stain normalization tasks to reverse this negative potential. With machine learning, this study evaluated the staining variance between different laboratories on three tissue types. We received H&E-stained slides from 66 different laboratories. Each slide contained kidney, skin, and colon tissue sampl…
From ‘no dogs here!’ to ‘beware of the dog!’ : restricting dog signs as a reflection of social norms
2019
Signs in public space reflect ‘normalcy’ in a community. The authors ask what restricting signs tell us about a society? In order to explore the system and variation in the ways dog signs manifest different norms and control, they compare two different data sets: dog signs in a Northern European town, Jyväskylä in Finland, and two Eastern European villages in Romania. They apply a qualitative methodology based on visual communication, geosemiotics and linguistic landscape studies. The focus of the article is on the resources of addressing and the visual semiotics of the image. The investigated communities seem to create a complementary distribution of what they regulate that is also displa…
Pyhäpäivien vietto varhaismodernin ajan Savossa (vuoteen 1710)
2016
In this dissertation, I study the observance of holy days among the peasantry in the early modern province of Savo, located on the eastern periphery of the Swedish kingdom (today Eastern Finland). I examine the practices, norms and meanings related to the observance of holy days both within and outside the Church, and analyse the changes and continuities in the post-reformation period. As the main sources of the study, I use district court records and visitation records mainly from the period 1639–1712. I analyse the cases with a micro-historical perspective and an anthropological approach. The lived religion of the peasantry was constituted especially through practices that were connected …
