Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Updating the Incomplete MOLS Table for v $v$ up to 100

Journal of Combinatorial Designs, EarlyView.
ABSTRACT Incomplete transversal designs have wide application in the construction of other designs such as transversal designs, block designs, frames, statistical designs, and Latin rectangles. Other areas where they are used include telecommunications and network codes, obtaining physically unclonable functions, frequency hopping sequences and ...

A Novel Orthogonal TU¯ Chebyshev Polynomial Basis for High-Accuracy Solution of Fractional Integro-Differential Equations

Journal of Mathematics
The main question addressed in this study is whether a newly constructed orthogonal basis, which is a combination of first- and second-kind Chebyshev polynomials, can provide a more accurate and efficient numerical method for solving fractional integro ...

Adaptive Spectral Analysis of Umbilical Venous Doppler Maternal–Fetal Power Ratio for Preeclampsia Risk Assessment

Journal of Ultrasound in Medicine, EarlyView.
Objectives To develop and evaluate adaptive spectral analysis for deriving the maternal–fetal power ratio (MFPR) from umbilical venous Doppler recordings and to assess MFPR for subsequent preeclampsia (PEC) risk discrimination across recording durations.

Post‐release tracking to monitor success of black cockatoo rehabilitation in Western Australia

The Journal of Wildlife Management, EarlyView.
Post‐release tracking of rehabilitated black cockatoos in Western Australia showed high success (79.4%), with survival, self‐feeding, and flock reintegration achieved by most birds. Larger resident flocks were significantly associated with improved post‐release outcomes.

Parallel Vector Processing in Optical Computing With Jacobi Time‐Wave Packets

Laser &Photonics Reviews, EarlyView.
Functionality of a single neuron and state of the art photonic acceleration with a Mach‐Zehnder‐interferometer (MZI) mesh (i), a crossbar array (ii) and a micro ring resonator (MRR) array (iii). In the proposed Jacobi time‐wave packet approach (iv) a single modulator (here a ring modulator) is performing the whole scalar vector product in a single ...

Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

Laser &Photonics Reviews, EarlyView.
A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Spectral analysis for the exceptional Xm-Jacobi equation

Electronic Journal of Differential Equations, 2015
We provide the mathematical foundation for the $X_m$-Jacobi spectral theory. Namely, we present a self-adjoint operator associated to the differential expression with the exceptional $X_m$-Jacobi orthogonal polynomials as eigenfunctions.

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers

Laser &Photonics Reviews, EarlyView.
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐
