A Scalable and Resource‐Efficient Pipelined p‐Computer for Probabilistic Ising Machines

open access: yesAdvanced Intelligent Systems, EarlyView.
(a) Block diagram of the portfolio optimization problem: given M assets, the goal is to determine the optimal weights w that maximize the expected return (based on the mean historical assets return u), while minimizing the risk, quantified by the assets covariance matrix S.

Several Characterizations of Δh-Doped Special Polynomials Associated with Appell Sequences

open access: yes, 2023
The study presented in this paper follows the line of research created by the fact that by employing the monomiality principle, new outcomes are produced.

Lasso for hierarchical polynomial models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

The Reduction Theorem for Leavitt Path Algebras of Labeled Graphs and Its Applications

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We introduce a notion of labeled cycle for normal labeled spaces and prove a reduction theorem for Leavitt path algebras associated with labeled graphs. We show that every nonzero element can be reduced, by suitable left and right multiplication, either to a nonzero scalar multiple of a projection or to a polynomial supported on a labeled ...

Lyapunov‐Function‐Based Stability Region Estimation in Transient Stability Assessment of Inverter‐Based Resources: A Review

open access: yesHigh Voltage, EarlyView.
ABSTRACT Electric power systems are undergoing a fundamental transition from synchronous generator (SG)‐dominated systems to inverter‐based resource (IBR)‐dominated systems. Lyapunov‐ and energy‐function‐based direct methods provide an effective way to estimate the stability region, also known as the region of attraction (ROA), and have become a ...

Measure‐valued processes for energy markets

open access: yesMathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Random Turán Problems for Hypergraph Expansions

open access: yesRandom Structures &Algorithms, Volume 69, Issue 4, December 2026.
ABSTRACT Given an r0$$ {r}_0 $$‐uniform hypergraph F$$ F $$, we define its r$$ r $$‐uniform expansion F(r)$$ {F}^{(r)} $$ to be the hypergraph obtained from F$$ F $$ by inserting r−r0$$ r-{r}_0 $$ distinct vertices into each edge of F$$ F $$, and we define ex(Gn,pr,F(r))$$ \mathrm{ex}\left({G}_{n,p}^r,{F}^{(r)}\right) $$ to be the largest F(r)$$ {F ...

Maximal independence and regularity of Al/Si distributions in disordered phyllosilicates 2:1

open access: yesActa Crystallographica Section A, Volume 82, Issue 6, Page 472-485, November 2026.
The distribution of aluminium cations in disordered phyllosilicates is analysed according to the concepts of maximal independence and regularity.As an extension of previous works, we analyse regularity in disordered Al/Si distributions in phyllosilicates 2:1. The method is based on an analysis of maximal independent sets in a labelled quotient graph of

A note on the monomiality principle and generalized polynomials.

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2001
Summary: The monomiality principle is used to state generalized forms of the division algorithm and of the remainder theorem for families of polynomials written as linear combination of Hermite polynomials.
