• Selective Formation of S4- and T-Symmetric Supramolecular Tetrahedral Cages and Helicates in Polar Media Assembled via Cooperative Action of Coordination and Hydrogen-Bonds 

  Shi, Qixun; Zhou, Xiaohong; Yuan, Wei; Su, Xiaoshi; Neniškis, Algirdas; Wei, Xin; Taujenis, Lukas; Snarskis, Gustautas; Ward, Jas S; Rissanen, Kari; de Mendoza, Javier; Orentas, Edvinas (American Chemical Society, 2020)

  We report on the synthesis and self-assembly study of novel supramolecular monomers encompassing quadruple hydrogen-bonding motifs and metal coordinating 2,2’-bipyridine units. When mixed with metal ions such as Fe2+ or ...

• Abel transforms with low regularity with applications to x-ray tomography on spherically symmetric manifolds 

  Hoop, Maarten V de; Ilmavirta, Joonas (Institute of Physics, 2017)

  We study ray transforms on spherically symmetric manifolds with a piecewise C 1,1 metric. Assuming the Herglotz condition, the X-ray transform is injective on the space of L 2 functions on such manifolds. We also prove ...

• Asymmetric and symmetric fission of excited nuclei of 180,190Hg and 184,192,202Pb formed in the reactions with 36Ar and 40,48Ca ions 

  Bogachev, A. A.; Kozulin, E. M.; Knyazheva, G. N.; Itkis, I. M.; Itkis, M. G.; Novikov, K. V.; Kumar, D.; Banerjee, T.; Diatlov, I. N.; Cheralu, M.; Kirakosyan, V. V.; Mukhamejanov, Y. S.; Pan, A. N.; Pchelintsev, I. V.; Tikhomirov, R. S.; Vorobiev, I. V.; Maiti, M.; Prajapat, R.; Kumar, R.; Sarkar, G.; Trzaska, W. H.; Andreyev, A. N.; Harca, I. M.; Vardaci, E. (American Physical Society (APS), 2021)

  Background: Observation of asymmetric fission of 180Hg has led to intensive theoretical and experimental studies of fission of neutron-deficient nuclei in the lead region. Purpose: The study of asymmetric and symmetric ...

• Exponential transients in continuous-time symmetric Hopfield nets 

  Sima, Jiri; Orponen, Pekka (Springer-Verlag, 2001)

  We establish a fundamental result in the theory of continuous-time neural computation, by showing that so called continuous-time symmetric Hopfield nets, whose asymptotic convergence is always guaranteed by the existence ...

• Synthesis of C2-Symmetrical Bis-(β-Enamino-Pyran-2,4-dione) Derivative Linked via 1,6-Hexylene Spacer: X-ray Crystal Structures, Hishfeld Studies and DFT Calculations of Mono- and Bis-(Pyran-2,4-diones) Derivatives 

  Boraei, Ahmed T. A.; Haukka, Matti; Sarhan, Ahmed A. M.; Soliman, Saied M.; Al-Majid, Abdullah Mohammed; Barakat, Assem (MDPI AG, 2021)

  The synthesis of C2-symmetrical bis(β-enamino-pyran-2,4-dione) derivative 3 connected via 1,6-hexylene linker was reported for the first time. X-ray structures and Hirshfeld studies of the new bis- β-enamino-pyran-2,4-dione ...
