Two Vignettes On Full Rook Placements [PDF]
Using bijections between pattern-avoiding permutations and certain full rook placements on Ferrers boards, we give short proofs of two enumerative results.

Basic hypergeometric summations from rook theory
We employ a one-variable extension of q-rook theory to give combinatorial proofs of some basic hypergeometric summations, including the q-Pfaff-Saalsch\"utz summation and a 4phi3 summation by Jain.Comment: 12 ...

Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Rook placements and Jordan forms of upper-triangular nilpotent matrices [PDF]
The set of n by n upper-triangular nilpotent matrices with entries in a finite field F_q has Jordan canonical forms indexed by partitions lambda of n.

Fabrication process of phase change microcapsules using a Pickering emulsion template method and their subsequent applications. The increasing demand for efficient thermal energy storage systems has driven the development of phase change material microcapsules (PCMMs), which provide high energy‐storage density, reversible phase change, and reduced ...

Optimal softening for force calculations in collisionless N-body simulations
In N-body simulations the force calculated between particles representing a given mass distribution is usually softened, to diminish the effect of graininess. In this paper we study the effect of such a smoothing, with the aim of finding an optimal value

Abstract Objective To investigate the frequency, predictors, and clinical implications of diagnostic reassessment in patients previously diagnosed with childhood‐onset epilepsy during the transition period to adult care at a tertiary epilepsy center. Methods We conducted a retrospective cohort study of 317 patients previously diagnosed with childhood ...

Invisible permutations and rook placements on a Ferrers board
We study non-attacking rook placements on a Ferrers board by extending them to certain permutation matrices, called invisible permutations. By introducing a length function on rook placements, we define a rook length polynomial \(\text{RL}_ k(\lambda, q)\) for a given number \(k\) of rooks and a Ferrers board \(F_ \lambda\). We prove that \(\text{R}_ k(

ABSTRACT This pilot study investigated how the narrative‐rich Chinese AAA game Black Myth: Wukong supports advanced Mandarin learners. Using reflective journals, semi‐structured interviews, and exploratory electroencephalogram (EEG), we examined learners' cognitive, affective, and cultural experiences.

ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).
