Disordered hyperuniformity in superconducting vortex lattices
2020
Particles occupying sites of a random lattice present density fluctuations at all length scales. It has been proposed that increasing interparticle interactions reduces long range density fluctuations, deviating from random behaviour. This leads to power laws in the structure factor and the number variance that can be used to characterize deviations from randomness which eventually lead to disordered hyperuniformity. It is not yet fully clear how to link density fluctuations with interactions in a disordered hyperuniform system. Interactions between superconducting vortices are very sensitive to vortex pinning, to the crystal structure of the superconductor and to the value of the magnetic …
Some applications of the Chambers isoperimetric inequality
2022
In this paper, using the Chambers isoperimetric inequality, we introduce the notion of weighted rearrangement of a function associated to the measure $f dx$, where $f(x)=e^{g(|x|)}$ for $x \in \mathbb{R}^n}$, with $g$ smooth, convex and even. Then we give some of its applications to variational inequalities and PDEs via weighted symmetrization.
Five-to-Six Membered Ring-rearrangements in the Reaction of 5-Perfluoroalkyl-1,2,4-oxadiazoles with Hydrazine and Methylhydrazine
2006
The hydrazinolysis reaction of 5-perfluoroalkyl-1,2,4-oxadiazoles with hydrazine or methylhydrazine as bidentate nucleophiles has been investigated. The reaction occurred through the addition of the bidentate nucleophile to the C(5)-N(4) double bond of the 1,2,4-oxadiazole followed by ring-opening and ring-closure (ANRORC) involving the second nucleophilic site of the reagent. This ring-closure step could involve either the original C(3) of the 1,2,4-oxadiazole (giving a five-to-five membered ring rearrangement) or an additional electrophilic center linked to it (exploiting a five-to-six membered ring rearrangement). An alternative initial nucleophilic attack may involve the additional elec…

Tyytyväisyys työaikapankkiin
2009
Tutkimuksessa tarkasteltiin työaikapankkiin tyytyväisyyttä ennustavia tekijöitä. Tutkimus perustuu yhdeksässä työorganisaatiossa tehdyn kyselyn aineistoon (N = 268). Analyysit suoritettiin polkuanalyysina, jolloin selittäjien kausaalinen järjestys ja keskinäinen riippuvuus pystyttiin ottamaan huomioon. Selvä enemmistö vastaajista oli tyytyväisiä työaikapankkiin. Tyytyväisyyttä lisäsivät mahdollisuus kokonaisen vapaa-päivän viettämiseen säästetyistä tunneista, korkea asema organisaatiossa sekä työntekijöiden organisaation johdolta saama tuki. Tyytyväisyyttä heikensivät ongelmat säästettyjen vapaiden käytössä sekä työaikatilin saldorajojen huono mitoitus suhteessa työtehtävien vaativuuteen. K…
Family and work-related risk factors in children's social–emotional well-being and parent–educator cooperation in flexibly scheduled early childhood …
2023
Non-standard work schedules (NSWS) have become typical, but their associations with childcare arrangements and children's well-being are unknown. This study explores how risk factors are associated with the social–emotional well-being of girls and boys using flexibly scheduled early childhood education and care. Furthermore, the study investigates whether well-functioning cooperation between parents and educators buffers the negative effects of the risk factors. This study, which is a part of a larger survey carried out in three European countries, reports Finnish parents' (N = 146) perspectives. The results showed that high parental stress was associated with low child well-being. Strong p…

Exchange Rate Arrangements in Central and Eastern European Countries – Evolutions and Characteristics
2007
The process of choosing the exchange rate regime for the new EU member states has been influenced by other criteria than the traditional ones, which belong to macroeconomic criteria. This paper make a comparative analyze of the exchange rate arrangements in Central and Eastern European after 1990. These arrangements are dynamic on the one hand due to their permanent diversification and on the other hand because the values established this way are rapidly changing. In essence, they differ according to the degree of flexibility adopted when the exchange rate is established: from more rigid forms – currency board or pegging the currency to a foreign currency – to free floating.
Double non-taxation and the use of hybrid entities
2017
La tesis analiza la interacción entre la doble no imposición y el uso de entidades híbridas dentro del contexto internacional, lo que incluye la aplicación de tratados internacionales para evitar la doble imposición. En este sentido, y contrariamente a la opinión mayoritaria de la doctrina fiscal internacional, el autor argumenta que la doble no imposición debería ser entendida de acuerdo a su naturaleza de resultado, es decir, no debería considerarse per se como un problema internacional ni menos utilizarse como un elemento fundamental en el diseño de normas específicas anti-híbridos. De la misma manera, y contrariamente a la tendencia internacional en cuanto a alinear resultados tributari…
Data from: Disentangling structural genomic and behavioral barriers in a sea of connectivity
2018
Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing effects of gene flow to allow for adaptation and speciation. Chromosomal inversions act as an important mechanism maintaining isolating barriers, yet their role in sympatric populations and divergence with gene flow is not entirely understood. Here, we revisit the question whether inversions play a role in the divergence of connected populations of the marine fish Atlantic cod, by exploring a unique dataset combining whole-genome sequencing data and behavioral data obtained w…
