On commutative von Neumann regular rings and a question of Handelman

, 1995
The main purpose of this note is to answer a question of Handelman on right self-injective, directly finite, von Neumann regular rings. He asked if such a ring R is determined up to isomorphism by the Boolean space Spec B (R), where B(R) is the boolean ...

Too Complex to Choose? The Role of Heuristics in Shaping Farmers' Willingness to Pay for Income Stabilization Tool in Italy

Agribusiness, EarlyView.
ABSTRACT European agriculture is increasingly exposed to economic instability driven by extreme weather events, market volatility, and geopolitical tensions. To manage these growing risks, farmers are encouraged to adopt innovative risk management strategies such as the Income Stabilization Tool (IST), which offers protection against severe income ...

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

On semihereditary noncommutative polynomial rings

, 1980
McCarthy [4] showed that a polynomial ring over a commutative von Neumann regular ring is semihereditary. Camillo [1] proved the converse. In this paper we examine polynomial rings over von Neumann regular rings which are not necessarily commutative.

Semisimple Rings and Von Neumann Regular Rings of Generalized Power Series

Journal of Algebra, 1997
Let \((S,+,\leq)\) be a strictly ordered monoid and let \(R\) be a ring. The author defines the ring of generalized power series \(A=[R^{S,\leq}]\), with coefficients in \(R\) and exponents in \(S\) as the set of all functions \(f\colon S\to R\) such that \(\text{supp}(f)\) is artinian and narrow. The following main theorem is proved. Let \(R\) contain

Regular 𝑃.𝐼.-rings

, 1973
For a ring R R which satisfies a polynomial identity we show that the following are equivalent: (1) R R is von Neumann regular, (2) each two-sided ideal of R R is idempotent, and (3) each simple left (

Low‐Voltage Operation of IGZO Memtransistors Enabled by Coupling Enhancement Through 2T Drain‐Driven Operation for Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
A two‐terminal IGZO memtransistor enabling low‐voltage operation is demonstrated through coupling enhancement. By utilizing drain‐induced Fowler–Nordheim tunneling, the device achieves programming below 10 V with a large memory window and high on/off ratio.
