Nonlinear Neutral Delay Differential Equations: Novel Criteria for Oscillation and Asymptotic Behavior

Mathematics
This research deals with the study of the oscillatory behavior of solutions of second-order differential equations containing neutral conditions, both in sublinear and superlinear terms, with a focus on the noncanonical case. The research provides a careful analysis of the monotonic properties of solutions and their derivatives, paving the way for a ...

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

International Economic Review, EarlyView.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

Interest Rate Pegs and the Reversal Puzzle: On the Role of Anticipation

Journal of Money, Credit and Banking, EarlyView.
Abstract We revisit the reversal puzzle: a counterintuitive contraction of inflation in response to an interest rate peg. We show that its occurrence is intimately related to the degree of agents' anticipation. If agents perfectly anticipate the peg, reversals occur depending on the duration of the peg.

Extremely Fast Maximum Likelihood Estimation of High‐Order Autoregressive Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of exact maximum likelihood estimation of potentially high‐order (p>50$$ p>50 $$) autoregressive models. We propose an extremely fast coordinate‐wise algorithm for fitting autoregressive models. This fast algorithm exploits several properties of the negative log‐likelihood when parameterised in terms of partial ...

New evidence on the formation conditions of the Libyan Desert Glass (Western Egypt): Clues from a dendritic zircon inclusion

Meteoritics &Planetary Science, EarlyView.
Abstract Libyan Desert Glass (LDG) is an ~29 million years old, silica‐rich glass found in Western Egypt. Whether this glass formed in an impact cratering context associated with the hypervelocity collision of a cometary/asteroidal body or radiative heating during an airburst is debated. Determination of the formation temperatures and pressures of rare

Semiparametric regression for circular response with application in ecology

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT A regression model for a circular response variable depending on a linear or a circular predictor is presented in this paper. The conditional density belongs to a parametric flexible family that allows for asymmetry and varying peakedness around the modal direction.

Function Art: Linking Mathematics, Technology, and Visual Arts

School Science and Mathematics, EarlyView.
ABSTRACT This study investigated students' understanding of mathematical functions and strategies to create artwork using GeoGebra. It was framed by the principles of constructionism and examined how students use functions in creating artworks. We gathered data from students' artworks using the Algebra view and the Construction Protocol in the GeoGebra

Computational study of the excitation of human induced pluripotent stem cell‐derived cardiomyocytes

Experimental Physiology, EarlyView.
Abstract Human induced pluripotent stem cell‐derived cardiomyocytes (hiPSC‐CMs) have proven to be a revolutionary advance for tissue engineering, disease modelling, and drug testing and discovery. Computational modelling enables detailed electrophysiological analysis that is otherwise difficult or impossible to achieve under strictly experimental ...

Frequency Analysis of a Superconducting Magnetic Bearing System in Ring Spinning Using an Eddy Current Damper

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.
