Extrapolative Analysis of Fast-Switching Free Energy Estimates in a Molecular System [PDF]
arXiv, 2001 We perform an extrapolative analysis of "fast-growth" free-energy-difference (DF) estimates of a computer-modeled, fully-solvated ethane<->methanol transformation. The results suggest that extrapolation can greatly reduce the systematic error in DF estimated from a small number of very fast switches.

Random Polygons and Estimations of π
Open Mathematics, 2019 In this paper, we study the approximation of π through the semiperimeter or area of a random n-sided polygon inscribed in a unit circle in ℝ2. We show that, with probability 1, the approximation error goes to 0 as n → ∞, and is roughly sextupled when ...

Closed‐Loop Recyclable High‐Performance Aerogels Derived from Polystyrene
Advanced Functional Materials, EarlyView.Upcycling of commercial polystyrene waste into closed‐loop recyclable high‐performance aerogels is presented. These PSAs are made from aminated PS waste using a dialdehyde crosslinker. The PSAs are highly porous, thermally superinsulating, and intrinsically hydrophobic.

Extrapolation and weighted norm inequalities in the variable Lebesgue spaces [PDF]
arXiv, 2014 We extend the theory of Rubio de Francia extrapolation, including off-diagonal, limited range, and $A_{\infty}$ extrapolation, to the weighted variable Lebesgue spaces. As a consequence we are able to show that a number of different operators from harmonic analysis are bounded on these spaces.

Advanced Functional Materials, EarlyView.Highlighting the importance of anode microstructure for alkaline OER, ultrasonic spray coating is applied at two different temperatures. This proof‐of‐concept approach yielded varied morphologies, structures, wettability and mechanical strength. These variations led to noticeable performance changes in activity after 8 h of measurements, comparing the ...

On the Convergence of (Stochastic) Gradient Descent with Extrapolation for Non-Convex Optimization [PDF]
arXiv, 2019 Extrapolation is a well-known technique for solving convex optimization and variational inequalities and recently attracts some attention for non-convex optimization. Several recent works have empirically shown its success in some machine learning tasks. However, it has not been analyzed for non-convex minimization and there still remains a gap between

Up-to-date probabilistic temperature climatologies
Environmental Research Letters, 2015 With ongoing global warming, climatologies based on average past temperatures are increasingly recognized as imperfect guides for current conditions, yet there is no consensus on alternatives.

Advanced Functional Materials, EarlyView.This study presents an electronic fine‐tuning (EFT) strategy to optimize the electronic structures of Ru species and single‐atom Zn sites by the virtue of layered nanosheets, significantly enhancing ORR and HER activities. Spectroscopic analysis and theoretical calculations uncover that this EFT effect breaks the ORR scaling limitation and positions ...

Applications of band-limited extrapolation to forecasting of weather and financial time series [PDF]
arXiv, 2019 This paper describes the practical application of causal extrapolation of sequences for the purpose of forecasting. The methods and proofs have been applied to simulations to measure the range which data can be accurately extrapolated. Real world data from the Australian Stock exchange and the Australian Bureau of Meteorology have been tested and ...
