Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Arithmatical consequences of two identities of B. Gordon
International Journal of Mathematics and Mathematical Sciences, 1979 From two partition identities of Basil Gordon the author derives two recursive formulas for the sum-of-divisors function. A third application yields an alternate proof of Rmanujan's theorem on the divisibility of certain values of the partition function ...

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

Ideals and Green's relations in ordered semigroups
International Journal of Mathematics and Mathematical Sciences, 2006 Exactly as in semigroups, Green's relations play an important role in the theory of ordered semigroups—especially for decompositions of such semigroups.

Recursive and Cyclic Constructions for Double‐Change Covering Designs
Journal of Combinatorial Designs, Volume 34, Issue 4, Page 198-209, April 2026.ABSTRACT A double‐change covering design (DCCD) is a v‐set V and an ordered list L of b blocks of size k where every pair from V must occur in at least one block and each pair of consecutive blocks differs by exactly two elements. It is minimal if it has the fewest blocks possible and circular when the first and last blocks also differ by two elements.

How I Do It: The Transtracheal Approach for Awake Cricopharyngeal Botulinum Toxin Injection
The Laryngoscope, Volume 136, Issue 4, Page 1683-1686, April 2026.This transtracheal technique for cricopharyngeal botulinum toxin injection is a safe and effective option for chemodenervation of this muscle in the awake patient. Its advantages include reduced risk of toxin spread to intrinsic laryngeal muscles, the ability to administer higher doses of botulinum toxin, improved access to the entire length of the ...
