Four Inequivalent Ternary Rank-90 Decompositions of ⟨3,5,8⟩ over ℤ

We report four mutually inequivalent exact algorithms for the product of a 3×5 by a 5×8 matrix, each using 90 multiplications in which every coefficient is −1, 0 or +1. Rank 90 is the best rank published for ⟨3,5,8⟩ in any coefficient domain; the rank-90 scheme in the public cata...

Beyond grades: soft skills and employability readiness among Indonesian university students

Purpose This study examines the structural relationships among academic performance, soft skills, career clarity and perceived employability readiness among Indonesian university students. Because respondents were current undergraduate students, employability is framed as readine...
