Conformal Vortex Crystals

open access: yes, 2017
We investigate theoretically globally nonuniform configurations of quantized-flux vortices in clean superconductors trapped by an external force field that induces a nonuniform vortex density profile.

Chirped arrays of diode lasers for supermode control [PDF]

open access: yes, 1984
We propose nonuniform structures of phase-locked diode lasers, which make it possible to discriminate efficiently against all the higher order array supermodes (lateral modes).

A Design Methodology for Low-Loss Interconnects Featuring Air Cavities and Periodically Nonuniform Widths

open access: yesApplied Sciences
Power consumption in interconnects is a critical constraint on performance improvements in integrated circuits. This paper proposes a novel design methodology to minimize loss in interconnects and address this limitation.

Maximizing Energy Output of Photovoltaic Systems: Hybrid PSO-GWO-CS Optimization Approach

open access: yesJournal of Techniques, 2023
Photovoltaic (PV) systems suffer from partial shade and nonuniform irradiance conditions. Meanwhile, each PV module has a bypass shunt diode (BSD) to prevent hotspots.

The Effects of Nonuniform Illumination on the Electrical Performance of a Single Conventional Photovoltaic Cell

open access: yesInternational Journal of Photoenergy, 2015
Photovoltaic (PV) concentrators are a promising approach for lowering PV electricity costs in the near future. However, most of the concentrators that are currently used for PV applications yield nonuniform flux profiles on the surface of a PV module ...

Nonuniform Dichotomy Spectrum and Normal Forms for Nonautonomous Differential Systems [PDF]

open access: yes, 2014
The aim of this paper is to study the normal forms of nonautonomous differential systems. For doing so, we first investigate the nonuniform dichotomy spectrum of the linear evolution operators that admit a nonuniform exponential dichotomy, where the ...

A Joint Criterion for Reachability and Observability of Nonuniformly Sampled Discrete Systems

open access: yes, 2010
A joint characterization of reachability (controllability) and observability (constructibility) for linear SISO nonuniformly sampled discrete systems is presented.

Generalizations of the sampling theorem: Seven decades after Nyquist [PDF]

open access: yes, 2001
The sampling theorem is one of the most basic and fascinating topics in engineering sciences. The most well-known form is Shannon's uniform-sampling theorem for bandlimited signals.

Differential Item Functioning on the Patient Health Questionnaire 8 by Disease Subtype, Language, Sex, and Age Among People With Systemic Sclerosis: A Scleroderma Patient‐Centered Intervention Network Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.
