A metric discrepancy result for lacunary sequences [PDF]

open access: yesProceedings of the American Mathematical Society, 2012
In 1975, [Acta Arith. 26, 241--251 (1975; Zbl 0263.10020)] \textit{W. Philipp} proved the bounded law of the iterated logarithm (LIL) for the discrepancy of lacunary sequences. In 2008, the first author of the present paper under review developed a new technique to calculate the exact value of the limsup in the LIL for special lacunary sequences; it ...

Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

DFT Study of Halide‐Free Mechanism of the CO2 Cycloaddition onto Epoxide by [PW11O39{Zn(H2O)}]5−: Evidences for the Formation of Hydrogencarbonate Intermediates

open access: yesChemCatChem, Volume 17, Issue 15, August 7, 2025.
The computational study, sustained by experimental data, of the catalytic activity of [PW11O39{Zn(H2O)}]5− in CO2 cycloaddition to epoxide highlights how the carbonic anhydrase‐like character of this complex couples to the versatile binding properties of the polyoxometalate in this reaction pathway. Abstract The intertwined experimental and theoretical

Lacunary statistical convergence and inclusion properties between lacunary methods

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
A lacunary sequence is an increasing integer sequence θ={kr} such that kr−kr−1→∞ as r→∞. A sequence x is called sθ-convergent to L provided that for each ϵ>0, limr(1/(kr−kr−1)){the number of   kr ...

Highly Shielded Peroxo‐Cerium(IV)‐Containing Polyoxometalate: Synthesis, Structure, and Oxidative Studies

open access: yesChemistryEurope, Volume 3, Issue 4, July 14, 2025.
The peroxo‐di‐cerium(IV)‐di‐lithium‐containing 32‐tungsto‐4‐phosphate [(CeIV2O2)Li2(P2W16O59)2]16− (Ce2Li2P4W32) is synthesized and structurally characterized. This peroxo‐polyanion demonstrates remarkable stability in solution across a broad pH range.

The Role of Lacunary Statistical Convergence for Double sequences in Neutrosophic Normed Spaces [PDF]

open access: yesNeutrosophic Sets and Systems
This paper introduces and explores the concept of lacunary statistical convergence of double sequence within the framework neutrosophic normed spaces. Neutrosophic normed spaces extend classical normed spaces by incorporating neutrosophic numbers, which ...

Double Lacunary Density and Some Inclusion Results in Locally Solid Riesz Spaces

open access: yesAbstract and Applied Analysis, 2013
We define the notions of double statistically convergent and double lacunary statistically convergent sequences in locally solid Riesz space and establish some inclusion relations between them.

Discatenated and lacunary recurrences [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Recursive sequences with gaps have been studied previously. This paper considers some elementary properties of such sequences where the gaps have been created on a regular basis from sequence to sequence – ‘discatenated’ (systematic gaps) and ‘lacunary’

Biomimetic Hierarchical Construction of Anti‐Tumor Polyoxopalladates for Cancer Therapy

open access: yesAngewandte Chemie, Volume 137, Issue 23, June 2, 2025.
Engineering of lacunary polyoxopalladates resulted in a hierarchical assembly that resembles the construction of biomacromolecules. An ordered structural evolution from monomer via dimer to supramolecular aggregates was achieved by cooperative covalent and supramolecular bonding effects, resulting in enhanced anti‐tumor activity via DNA damage ...
