• Crystal structure and Hirshfeld surface analysis of poly[[bis[μ4-N,N′-(1,3,5-oxadiazinane-3,5-diyl)bis(carbamoylmethanoato)]nickel(II)tetrapotassium] 4.8-hydrate] 

  Plutenko, Maksym O.; Haukka, Matti; Husak,Alina O.; Iskenderov, Turganbay, S.; Mulloev, Nurullo U. (International Union of Crystallography (IUCr), 2021)

  The title compound, {[K4Ni2(C7H6N4O7)2]·4.8H2O}n, was obtained as a result of a template reaction between oxalohydrazide­hydroxamic acid, formaldehyde and nickel(II) nitrate followed by partial hydrolysis of the formed ...

  Plutenko, Maksym O.; Haukka, Matti; Husak, Alina O.; Golenya, Irina A.; Mulloev, Nurullo U. (International Union of Crystallography, 2021)

  The title compound, poly[triaquabis[4-N,N0 -(1,3,5-oxadiazinane-3,5-diyl)bis- (carbamoylmethanoato)]dinickel(II)tetrapotassium], [K4Ni2(C7H6N4O7)2- (H2O)3]n, is a second solvatomorph of poly[(4-N,N0 -(1,3,5-oxadiazinane-3,5- ...

• Frequency Change Patterns across Proficiency Levels in Japanese EFL Learner Speech 

  Abe, Mariko (Centre for Applied Language Studies, University of Jyväskylä, 2014)

  This study investigated the overall patterns of variation across seven oral proficiency levels of 1,263 Japanese EFL learners and native English speakers. The methodological approach combined a learner corpus, language ...

• Dung beetle community patterns in Western Europe : responses of Scarabaeinae to landscape and environmental filtering 

  Leandro, Camila; Jones, Mirkka; Perrin, William; Jay-Robert, Pierre; Ovaskainen, Otso (Springer, 2023)

  Context Mediterranean landscapes from Europe have undergone recent biodiversity changes. The intensification of human activities and the fragmentation of open habitats now affect many taxonomic groups, such as dung beetles, ...

• Approximating symmetrized estimators of scatter via balanced incomplete U-statistics 

  Dümbgen, Lutz; Nordhausen, Klaus (Springer, 2024)

  We derive limiting distributions of symmetrized estimators of scatter. Instead of considering all n(n−1)/2 pairs of the n observations, we only use nd suitably chosen pairs, where d≥1 is substantially smaller than n. It ...
