1. A Denseness Property of Stochastic Processes NSTL国家科技图书文献中心

Passeggeri, Riccardo -  《Journal of theoretical probability》 - 2025,38(1) - 共18页

摘要:In this work, we show the following general |  property of stochastic processes: Denseness of |  probability distributions extends to denseness of stochastic |  processes. In particular, for every d is an element of |  Ndocumentclass[12pt]{minimal} usepackage{amsmath} usepackage

2. Noninvasive Adaptive Control of a Class of Nonlinear Systems with Unknown Parameters NSTL国家科技图书文献中心

Rezaee, Hamed |  Renson, Ludovic -  《SIAM journal on applied dynamical systems》 - 2025,24(1) - 587~610 - 共24页

摘要:Control-based continuation (CBC) is a general |  and systematic method to explore the dynamic |  response of a physical system and perform bifurcation |  analysis directly during experimental tests. Although CBC |  has been successfully demonstrated on a wide range

3. A discrete dislocation plasticity assessment of the effective temperature in thermodynamic dislocation theory NSTL国家科技图书文献中心

Piao, Y. |  Balint, D. S. -  《Acta materialia》 - 2025,287 - 120808~ - 共15页

摘要:In this study, the effective temperature |  proposed by Thermodynamic Dislocation Theory (TDT) is |  assessed using Discrete Dislocation Plasticity (DDP | ): simulations were performed on small samples driven to a |  saturated dislocation density condition consistent with

4. Encounter-based model of a run-and-tumble particle with stochastic resetting NSTL国家科技图书文献中心

Bressloff, Paul C. -  《Journal of physics,A.Mathematical and theoretical》 - 2025,58(12) - 共30页

摘要:In this paper we analyze the effects of |  stochastic resetting on an encounter-based model of an |  unbiased run-and-tumble particle (RTP) confined to the |  half-line [0,infinity) with a partially absorbing |  wall at x = 0. The RTP tumbles at a constant rate

5. Montonen-Olive duality of gauged supergravity? NSTL国家科技图书文献中心

Duff, M. J. -  《Journal of physics,A.Mathematical and theoretical》 - 2025,58(5) - 共12页

摘要:The vanishing of the SO(N) beta-function of |  gauged N > 4 supergravity has long seemed like an |  answer looking for a question. Here we conjecture that |  it is a consequence of a Montonen-Olive style |  electric/magnetic duality.

6. Generalised killing spinors on three-dimensional Lie groups NSTL国家科技图书文献中心

Artacho, Diego -  《Manuscripta mathematica》 - 2025,176(1) - 共18页

摘要:We present a complete classification of |  invariant generalised Killing spinors on three-dimensional |  Lie groups. We show that, in this context, the |  existence of a non-trivial invariant generalised Killing |  spinor implies that all invariant spinors are

摘要:In d=4k+2 dimensions, p-form gauge fields |  (with p=2k) with self-dual field strengths couple |  naturally to dyonic branes with equal electric and |  magnetic charges. Sen's action for a p-form gauge field |  with self-dual field strength coupled to a spacetime

摘要:Shape sensing is critically important |  throughout the lifecycle of composite shell structures | , including the design, manufacturing, service, retirement | , and reuse phases. In the service phase, for instance | , shape-based structural integrity assessments can

摘要:The nonlinear stability of two-dimensional (2 | -D) plane Couette flow subject to a constant |  throughflow is analysed at finite and asymptotically large |  Reynolds numbers $textit {Re}$. The speed of this |  throughflow is quantified by the non-dimensional throughflow
