Nanoscale Confinement Enhances Ultrafast Demagnetization

Advanced Science, EarlyView.
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

Families of Smooth Rational Curves of Small Degree on the Fano Variety of Degree 5 of Main Series

Моделирование и анализ информационных систем, 2013
In this paper we consider some families of smooth rational curves of degree 2, 3 and 4 on a smooth Fano threefold X which is a linear section of the Grassmanian G(1, 4) under the Pl¨ucker embedding. We prove that these families are irreducible. The proof

The Graded Modules of Lie Superalgebra S(n) Over Prime Characteristic Fields

Journal of Harbin University of Science and Technology
The classification of simple Lie superalgebras over prime characteristic fields has not yet been solved, and the core issue is the classification of Cartan type Lie superalgebras.

Predictors and reduction techniques for irreducible reverse intertrochanteric fractures

Chinese Medical Journal, 2019
. Background:. Reverse intertrochanteric fractures are usually initially treated with closed reduction. However, sometimes these fractures are not amenable to closed reduction and require open reduction.

Hilbert's irreducibility theorem

, 2021
In its simplest form, the statement of Hilbert's irreducibility theorem says that for an irreducible polynomial in several variables, then there must be infinite ways to substitute integers for one of the parameters so that the resulting polynomial is ...

Inverse Design of Pre‐Strain via a Predictive Electromechanical Model for Enhanced Strain Sensing

Advanced Science, EarlyView.
An analytical electromechanical model rooted in microcrack evolution mechanics is globally calibrated from only eight pre‐strain datasets, enabling prediction of the complete sensing response at untested pre‐strain values within the calibrated design space (R2 > 0.99).

Transport equation for growing bacterial populations (II)

Electronic Journal of Differential Equations, 2012
This article studies the growing bacterial population. Each bacterium is distinguished by its degree of maturity and its maturation velocity. To complete the study in [3], we describe the bacterial profile of this population by proving that the ...

Irreducibility of Generalized Permutohedra, Supermodular Functions, and Balanced Multisets [PDF]

, 2023
We study generalized permutohedra and supermodular functions. Specifically we analyze decomposability and irreducibility for these objects and establish some asymptotic behavior.

Learning Work Function via Implicit Reasoning on Electrostatic Potential Landscapes

Advanced Science, EarlyView.
StructPot‐CLR establishes a cross‐modal contrastive learning framework that aligns the crystal structures of 2D materials with plane‐averaged electrostatic potential landscapes for physically informed work‐function prediction. The model achieves an MAE of 0.265 eV and an R2 of 0.902 on the held‐out test set while accurately preserving key morphological

Irreducible Decomposition of Curves

Journal of Symbolic Computation, 2002
This paper describes an algorithm for computing all irreducible components of a (not necessarily reduced) algebraic curve \(\mathcal C\) defined over \(\mathbb Q\) and embedded in a space of arbitrary dimension. The classical procedure is to take a generic projection of the curve to a plane and factorize the equation of the plane projection.
