Defining Fundamental Frequency for Almost Harmonic Signals

In this work, we consider the modeling of signals that are almost, but not quite, harmonic, i.e., composed of sinusoids whose frequencies are close to being integer multiples of a common frequency. Typically, in applications, such signals are treated as perfectly harmonic, allowing for the estimation of their fundamental frequency, despite the signals not actually being periodic. Herein, we provid

Framing Loss and Damage from climate change as the failure of Sustainable Development

Debates around “Loss and Damage” (L&D) from anthropogenic climate change have expanded rapidly since the adoption of the Warsaw International Mechanism (WIM) in 2013. Despite the urgent need for scientific best practice to inform policies to avoid, minimize and address L&D, the nascent research field faces internal disagreements and lacks a coherent conceptual framing, which hinder scienti

Elimination of 50% Iodine and Excellent Performance of Dye-Sensitized Solar Cell Enabled by TEMPO Radical Dendrimer-Iodide Dual Redox Systems

Detrimental effect of counter electrode corrosion, electrolyte leakage problem, and sublimation of iodine ions affect the performance and stability of dye-sensitized solar cells (DSSCs) based on a liquid redox electrolyte system. TEMPO/TEMPO+ is the most desirable one to replace the existing redox couples in liquid electrolyte owing to its rapid and reversible one electron kinetics, high diffusion

Adherence to beta-blockers and long-term risk of heart failure and mortality after a myocardial infarction

Aims: The aim of this study is to investigate the association between adherence to beta-blocker treatment after a first acute myocardial infarction (AMI) and long-term risk of heart failure (HF) and death. Methods and results: All patients admitted for a first AMI included in the nationwide Swedish web-system for enhancement and development of evidence-based care in heart disease evaluated accordi

Crowding in the Eye Lens : Modeling the Multisubunit Protein β-Crystallin with a Colloidal Approach

We present a multiscale characterization of aqueous solutions of the bovine eye lens protein βH crystallin from dilute conditions up to dynamical arrest, combining dynamic light scattering, small-angle x-ray scattering, tracer-based microrheology, and neutron spin echo spectroscopy. We obtain a comprehensive explanation of the observed experimental signatures from a model of polydisperse hard sphe
