Motion Planning of Uncertain Ordinary Differential Equation Systems [PDF]

open access: yes, 2011
This work presents a novel motion planning framework, rooted in nonlinear programming theory, that treats uncertain fully and under-actuated dynamical systems described by ordinary differential equations.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Uncertainty impact of isotherm models on liquid-phase adsorption thermodynamics: A bayesian inference perspective

open access: yesCleaner Chemical Engineering
Liquid-phase adsorption, a fundamental process where molecules in a liquid medium adhere to a solid surface, plays a crucial role in various chemical engineering applications such as wastewater decontamination and solvent recovery. These phenomena can be

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs

open access: yesAdvanced Functional Materials, EarlyView.
OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

Active Learning‐Accelerated Discovery of Fibrous Hydrogels with Tissue‐Mimetic Viscoelasticity

open access: yesAdvanced Functional Materials, EarlyView.
Active learning accelerates the design of fibrous hydrogels that mimic the viscoelasticity of native tissues. By integrating multi‐objective optimization and closed‐loop experimentation, this approach efficiently identifies optimal formulations from thousands of possibilities and decouples elasticity and viscosity. The resulting hydrogels offer tunable

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

open access: yesAdvanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

Conditional Versus Non-Conditional Probabilities in Quantum Bound States and their Relationship to the Heisenberg Uncertainty Principle and Statistical Mechanics

open access: yes, 2019
Recently, there have been a number of papers in the literature dealing with the calculation of Sp + Sx for quantum bound states. Here Sp is the momentum Shannon entropy -Sum 2fp*fp ln(fp) and Sx the position Shannon entropy -Sum 2 W(x)W(x) ln[W(x)] where W(x) is the wavefunction.

Experimental transition probabilities and oscillator strengths of singly ionised Xenon (Xe II) in the ultraviolet. A fully statistical approach to the determination of uncertainties

open access: yesSpectrochimica Acta Part B: Atomic Spectroscopy
We report 92 experimental values of transition probabilities and oscillator strengths for singly ionised xenon (Xe II) in the ultraviolet region (217–385 nm), 91 of which have been measured for the first time. The transition probabilities were obtained from the analysis of spectra emitted by a plasma in partial local thermodynamic equilibrium (pLTE ...

Stochastic forecast of the population of Poland, 2005-2050 [PDF]

open access: yes
Forecasting the population of Poland is very challenging. Firstly, the country has been undergoing rapid demographic changes. In the 1990s, they were influenced by the political, economic, and social consequences of the collapse of the communist regime ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
