Complexity phase transitions in instantaneous quantum polynomial-time circuits
Physical Review ResearchWe study the classical hardness of learning the output distribution from instantaneous quantum polynomial-time circuits with a varying density of two-qubit gates.

Geometry of a Family of Complex Polynomials
The PUMP Journal of Undergraduate Research, 2019 Let Pa be the family of complex-valued polynomials of the form p(z)=(z-a)(z-r)(z-s) with a in [0,1] and r and s on the unit circle. The Gauss-Lucas Theorem implies that the critical points of a polynomial in Pa lie in the unit disk. This paper characterizes the location and structure of these critical points.

Remarks on improved inversion attacks on nonlinear filter generators
Journal of Telecommunications and Information Technology, 2003 The subject of this paper are inversion attacks on stream ciphers (nonlinear filter generators), which were first introduced by Golić [3] and extended by Golić, Clark and Dawson [4].

Some Polynomials for Complex Quadrature [PDF]
Mathematics of Computation, 1971 Equal-weight Chebyshev quadrature is not generally used because the nodes become complex for large n. However, interest in these schemes remains because of recent work on minimal norm quadrature as well as schemes for doing real integrals of analytic functions by complex methods.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

A reconstruction theorem for complex polynomials
International Journal of Mathematics, 2015 Recently Takens' Reconstruction Theorem was studied in the complex analytic setting by Fornæss and Peters [Complex dynamics with focus on the real part, to appear in Ergodic Theory Dynam. Syst.]. They studied the real orbits of complex polynomials, and proved that for non-exceptional polynomials ergodic properties such as measure theoretic entropy are
