Advanced Science, EarlyView.Optimized 30 wt.% h‐BN/TPU fibers create a thermal conductivity of 2.08 W·m−1·K−1 while retaining mechanical compliance (422% elongation at break). Woven fabrics reduce surface temperature by 5.7°C under simulated solar irradiation. Glove integration enables localized fingertip heating at 29.55°C·s−1 with a thermal relaxation time of approximately 20 s.

Asymptotic analysis of powers of matrices [PDF]
International Journal of Mathematics and Mathematical Sciences, 2006 We analyze the representation of An as a linear combination of Aj, 0 ≤ j ≤ k − 1, where A is a k × k matrix. We obtain a first‐order asymptotic approximation of An as n → ∞, without imposing any special conditions on A. We give some examples showing the application of our results.

An Asymptotic Analysis of Nearly Unstable inar (1) Models [PDF]
This paper considers integer-valued autoregressive processes where the autoregression parameter is close to unity.We consider the asymptotics of this `near unit root' situation.The local asymptotic structure of the likelihood ratios of the model is ...

Advanced Science, EarlyView.Bulk and genotype‐imputed transcriptomes obscure the cellular drivers of complex disease. CausalCellInfer resolves them by integrating invariant marker selection, deep learning deconvolution, and regularized matrix completion. Applied to ∼500 000 UK Biobank participants across 29 traits, it uncovers hallmark cell‐type proportion shifts, including ...

Effects and optimization of pilot sequence length on rate in multiuser massive MIMO FDD system
Tongxin xuebao, 2018 The effect of pilot sequence length on the asymptotic performance of the ergodic rate was investigated for the multiuser massive multiple-input multiple-output (MIMO) frequency division duplexing (FDD) downlink system.Firstly,the analytical expression of
