A global perspective on western Mediterranean precipitation extremes

open access: yesnpj Climate and Atmospheric Science, 2022
The Mediterranean region has been declared a climate change hotspot due, among other reasons, to an expected increase in the torrential rains that frequently affect this densely populated area.

Non-linear Matter Spectra in Coupled Quintessence [PDF]

open access: yes, 2009
We consider cosmologies in which a dark-energy scalar field interacts with cold dark matter. The growth of perturbations is followed beyond the linear level by means of the time-renormalization-group method, which is extended to describe a multi ...

Colored visual stimuli evoke spectrally tuned neuronal responses across the central nervous system of zebrafish larvae

open access: yesBMC Biology, 2020
Background Visually guided behaviors such as optomotor and optokinetic responses, phototaxis, and prey capture are crucial for survival in zebrafish and become apparent after just a few days of development.

Gravimetry through non-linear optomechanics [PDF]

open access: yes, 2018
We propose a new method for measurements of gravitational acceleration using a quantum optomechanical system. As a proof-of-concept, we investigate the fundamental sensitivity for a cavity optomechanical system for gravitational accelerometry with a ...

Non-linear spectral estimation [PDF]

open access: yes, 1987
This work describes the use of constraints in variational procedures for spectral analysis. It is reported how the designer in a variational approach for spectral estimation has to select a set of constraints.

Fiber-Based SERS-Fluidic Polymeric Platforms for Improved Optical Analysis of Liquids

open access: yesBioengineering, 2023
Downsizing surface-enhanced Raman spectroscopy (SERS) within microfluidic devices has opened interesting perspectives for the development of low-cost and portable (bio)sensors for the optical analysis of liquid samples. Despite the research efforts, SERS-

Response Measurements on an Echinodome Subjected to Explosive Loading

open access: yesShock and Vibration, 1999
Free field explosion experiments were carried out to determine the general characteristics of the pressure pulse generated by a detonator underwater. An echinodome – an axisymmetric shell structure of optimum form – was subjected to a shock wave from the

A Software Architecture to Mimic a Ventricular Tachycardia in Intact Murine Hearts by Means of an All-Optical Platform

open access: yesMethods and Protocols, 2019
Optogenetics is an emerging method that uses light to manipulate electrical activity in excitable cells exploiting the interaction between light and light-sensitive depolarizing ion channels, such as channelrhodopsin-2 (ChR2).

Fractional Order Memristor No Equilibrium Chaotic System with Its Adaptive Sliding Mode Synchronization and Genetically Optimized Fractional Order PID Synchronization

open access: yesComplexity, 2017
This paper introduces a fractional order memristor no equilibrium (FOMNE) chaotic system and investigates its adaptive sliding mode synchronization. Firstly the dynamic properties of the integer order memristor no equilibrium system are analyzed.

From Non-Linear Knowledge to Non-Linear Trust

open access: yesSociological Journal, 2019
This article is devoted to disclosing the idea of trusting knowledge, which is laid out in the monograph “Trusting knowledge in conditions of social turbulence: risks, vulnerabilities, security challenges”. The genre of the article/review allowed for presenting the key positions of the sociological conception and the results of empirical research ...
