Racial Inequality, Growth and Distribution
Metroeconomica, EarlyView.ABSTRACT A post‐Keynesian‐Kaleckian model along structuralist lines is developed to incorporate the issue of racial inequality into the analysis of growth and distribution. It draws on ideas presented in the literature about the relationship between class inequality between capitalists and workers, and racial inequality between White and Black workers,

Market size and strategic interaction in pharmaceutical price regulation
The Scandinavian Journal of Economics, EarlyView.Abstract We present a model of optimal regulation in the presence of spillover effects and asymmetric countries, and we use it to study strategic interaction among countries in pharmaceutical price regulation, where the spillovers result from innovation in drug development.

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice
Experimental Physiology, EarlyView.Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

On‐Chip Learning With Crossbar Arrays for Adaptive Edge Intelligence
Advanced Computing, Volume 1, Issue 1, December 2026.Memristor crossbar arrays implemented on chip combines memory, computation, and learning. They allow for adapting the neural weights using the incoming sensor data. This architecture reduces data movement leading to low‐latency, energy‐efficient intelligence in edge while being reliability‐aware co‐design across devices, circuits, and algorithms that ...

On the Design of Model Predictive Setpoint Controllers for Nonholonomic Multibody Systems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Systems subject to constraints that are not integrable to position‐level constraints pose significant challenges for setpoint control. In particular, conventional linearization techniques may fail to yield controllable approximations, since certain directions of motion are only accessible through higher‐order interactions of the control inputs.

On computing local monodromy and the numerical local irreducible decomposition
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Sparsity issues in the computation of Jacobian matrices
Proceedings of the 2002 international symposium on Symbolic and algebraic computation, 2002 The knowledge of sparsity information plays an important role in efficient determination of sparse Jacobian matrices. In a recent work, we have proposed sparsity-exploiting substitution techniques to determine Jacobian matrices. In this paper, we take a closer look at the underlying combinatorial problem.

Noncommutative-nilpotent matrices and the jacobian conjecture
Linear and Multilinear Algebra, 1996We prove that a polynomial map F = X + H ∈ k[X] with homogeneous H(k is a field of characteristic zero) is linear triangularizable if and only if the Jacobian matrix J(H) is a noncommutative-nilpotent matrix.

On the Estimation of Sparse Jacobian Matrices
IMA Journal of Applied Mathematics, 1974Summary: We show how to use known constant elements in a Jacobian matrix to reduce the work required to estimate the remaining elements by finite differences.
