On the local convergence of Newton's method under generalized conditions of Kantorovich [PDF]

, 2013
Following an idea similar to that given by Dennis and Schnabel (1996) in [2], we prove a local convergence result for Newton's method under generalized conditions of Kantorovich type. © 2013 Elsevier Ltd.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

Polymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...

Validation of Neural Network Controllers for Uncertain Systems Using the Keep‐Close Approach: Robustness Analysis and Safety Verification

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The safety verification of neural network (NN) controllers operating in uncertain environments characterized by unmodeled dynamics, nonlinearities, and time delays remains a fundamental challenge in robust control analysis. This article introduces a novel method, termed Keep‐Close, for analyzing the performance and robustness of uncertain ...

Sequence-encoded determinants drive distinct early aggregation pathways and different structural outcomes in PNT1 fibrils across Henipavirus members. [PDF]

Protein Sci
Abstract Protein aggregation is increasingly recognized as a biologically relevant process in viral proteins, yet the molecular determinants governing such phenomena remain poorly understood. Intrinsically disordered proteins (IDPs) are ubiquitous in viral proteomes, where conformational plasticity not only enables functional diversity but also permits

Third-order modification of Newton's method [PDF]

, 2007
In this paper, we present a new modification of Newton's method for solving non-linear equations. Analysis of convergence shows that the new method is cubically convergent. Numerical examples show that the new method can compete with the classical Newton'

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.
