Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells
Advanced Materials, EarlyView.Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Properties of virtual MIMO signal and interference in cooperation cognitive networks
Tongxin xuebao, 2012 A virtual MIMO scheme based on cooperation of the prim and secondary users was proposed in the wireless cognitive networks.The tight upper and lower bounds about the complimentary cumulative distribution function of the virtual MIMO signal and ...

Advanced Materials, EarlyView.Organic artificial neurons couple mechanical deformation and ionic environments through nonlinear mechano‐electrochemical dynamics. Mechanical strain and electrolyte concentration reshape their nonlinear electrical characteristics, programming excitatory or inhibitory spiking responses that mimic mechanosensitive biological neurons and enable ...

Asymptotic Properties of Spearman's Rank Correlation for Variables with Finite Support. [PDF]
PLoS ONE, 2016 The asymptotic variance and distribution of Spearman's rank correlation have previously been known only under independence. For variables with finite support, the population version of Spearman's rank correlation has been derived.

The Asymptotic Distribution of Extreme Sums
The Annals of Probability, 1991 Let \(X_{1,n}\leq\ldots\leq X_{n,n}\) be the order statistics of \(n\) independent random variables with a common distribution \(F\), and let \(T_ n=X_{n,n}+\ldots+X_{n+1-k(n),n}\), where \(\{k(n)\}\) is a sequence of positive integers such that \(k(n)\rightarrow\infty\) and \(k(n)/n\rightarrow\alpha\) as \(n\rightarrow\infty\), with \(0\leq\alpha0 ...

Advanced Materials Technologies, EarlyView.Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined

Measures of Dispersion and Serial Dependence in Categorical Time Series
Econometrics, 2019 The analysis and modeling of categorical time series requires quantifying the extent of dispersion and serial dependence. The dispersion of categorical data is commonly measured by Gini index or entropy, but also the recently proposed extropy measure can

Asymptotic Formula for Noncentral F-Distribution [PDF]
The Egyptian Statistical Journal, 1977 The method of small parameter is used to obtain a new representation for the distribution of the variance ratio when the Null-Hypothesis is not true. Although the new formula is supposed to be valid only when λ(the non-centrality parameter) is large, yet

Advanced Materials Technologies, EarlyView.Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
