Broadband Mode Converter With Customizable Modal Ratio Leveraging Subwavelength Engineering for Advanced Multimode Silicon Photonics

Laser &Photonics Reviews, EarlyView.
This work introduces a customizable mode converter for multimode silicon photonics, enabling precise control over the conversion ratio between optical modes. The device operates across a broad wavelength range (1350–1700 nm) with 15 distinct conversion levels.

The bifurcation locus for numbers of bounded type

, 2019
We define a family B(t) of compact subsets of the unit interval which generalizes the sets of numbers whose continued fraction expansion has bounded digits. We study how the set B(t) changes as one moves the parameter t, and see that the family undergoes

On the Transformative Nature of Luxury Consumption and Consumer Well‐Being: A Systematic Literature Review and Research Agenda

Psychology &Marketing, EarlyView.
ABSTRACT Consuming luxury products and services has received little systematic attention as a potential pathway to consumer well‐being, despite sporadic evidence suggesting that luxury experiences may catalyse self‐transformational processes and happiness‐related outcomes.

Interruption of torus doubling bifurcation and genesis of strange nonchaotic attractors in a quasiperiodically forced map : Mechanisms and their characterizations

, 2000
A simple quasiperiodically forced one-dimensional cubic map is shown to exhibit very many types of routes to chaos via strange nonchaotic attractors (SNAs) with reference to a two-parameter $(A-f)$ space.

Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.

Controlling hopf bifurcations: Discrete-time systems

Discrete Dynamics in Nature and Society, 2000
Bifurcation control has attracted increasing attention in recent years. A simple and unified state-feedback methodology is developed in this paper for Hopf bifurcation control for discrete-time systems. The control task can be either shifting an existing

Numerical Study of the Oscillatory Convergence to the Attractor at the Edge of Chaos

, 2005
This paper compares three different types of ``onset of chaos'' in the logistic and generalized logistic map: the Feigenbaum attractor at the end of the period doubling bifurcations; the tangent bifurcation at the border of the period three window; the ...

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

System as a Unifying Process: An Onto‐Epistemic Notion of System

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article proposes an onto‐epistemic notion of system as a relational process of unifying a multiplicity of actuals and abstractions into an actual unity, thereby encompassing concreteness and abstraction onto the same plane. This notion rejects the opposition between constructivism and realism within systems studies, the excessive focus on

Bifurcations and degenerate periodic points in a three dimensional chaotic fluid flow

, 2016
Analysis of the periodic points of a conservative periodic dynamical system uncovers the basic kinematic structure of the transport dynamics, and identifies regions of local stability or chaos.
