Sylvester Hadamard matrices revisited
Special Matrices, 2014 In this work we revisited some properties of Sylvester Hadamard matrices of order 2k. Based onlyon the existence of a base from which any Sylvester Hadamard matrix can be constructed, we prove that theirrows (columns) are closed under addition and that ...

MERSENNE AND HADAMARD MATRICES CALCULATION BY SCARPIS METHOD [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2014 Purpose. The paper deals with the problem of basic generalizations of Hadamard matrices associated with maximum determinant matrices or not optimal by determinant matrices with orthogonal columns (weighing matrices, Mersenne and Euler matrices, ets ...

BCCB complex Hadamard matrices of order 9, and MUBs [PDF]
, 2016 A new type of complex Hadamard matrices of order 9 are constructed. The studied matrices are symmetric, block circulant with circulant blocks ( B C C B ) and form an until now unknown non-reducible and non-affine two-parameter orbit.

Ranks and Kernels of Codes From Generalized Hadamard Matrices [PDF]
IEEE Transactions on Information Theory, 2015 The ranks and kernels of generalized Hadamard matrices are studied. It is proved that any generalized Hadamard matrix H(q, λ) over Fq, q > 3, or q = 3 and gcd(3, λ) ≠ 1, generates a self-orthogonal code. This result puts a natural upper bound on the rank

Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains
Advanced Robotics Research, EarlyView.How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

Generalization of Scarpis’ theorem on Hadamard matrices [PDF]
, 2016 A -matrix H of order m is a Hadamard matrix if , where T is the transposition operator and is the identity matrix of order m. J. Hadamard published his well known paper on Hadamard matrices in 1893.

Advanced Science, EarlyView.This study employs longitudinal fluorescence imaging in transgenic mice to map post‐craniotomy cortical recovery. We identify distinct neuroimmune recovery phases: microglial structural inflammation peaks at ∼10 days, neuronal structural intensity peaks at ∼14 days and correlates with microglial activity, and functional network modularity is most ...

A class of cyclic (v; k1, k2, k3; λ) difference families with v ≡ 3 (mod 4) a prime
Special Matrices, 2016 We construct several new cyclic (v; k1, k2, k3; λ) difference families, with v ≡ 3 (mod 4) a prime and λ = k1 + k2 + k3 − (3v − 1)/4. Such families can be used in conjunction with the well-known Paley-Todd difference sets to construct skew-Hadamard ...
