Advanced Science, EarlyView.A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

Smoothed L-estimation of Regression Function
The Nadaraya-Watson nonparametric estimator of regression is known to be highly sensitive to the presence of outliers in data.This sensitivity can be reduced, for example, by using local L-estimates of regression.Whereas the local L-estimation is ...

Higher-Order Kernel Semiparametric M-Estimation of Long Memory [PDF]
Econometric interest in the possibility of long memory has developed as a flexible alternative to, or compromise between, the usual short memory or unit root prescriptions, for example in the context of modelling cointegrating or other relationships and ...

Advanced Science, EarlyView.Acoustic plasmons in Ti3C2Tx MXene strongly compress infrared electromagnetic fields and enhance light–matter interactions at the nanoscale. This platform couples broadband plasmon excitations with molecular vibrations, enabling simultaneous sensing of high‐ and low‐frequency vibrational modes in ultrathin PMMA and graphene oxide films, and extending ...

Asymptotic Expansions for Some Semiparametric Program Evaluation Estimators [PDF]
We investigate the performance of a class of semiparametric estimators of the treatment effect via asymptotic expansions. We derive approximations to the first two moments of the estimator that are valid to 'second order'.

Advanced Science, EarlyView.This study achieves the synergistic integration of self‐powered sensing and edge AI acceleration to establish a real‐time fault diagnosis system. The proposed TENG‐based self‐powered bearing sensor (NSE‐TBS) and FPGA‐accelerated edge AI framework fundamentally break through the inherent limitations of conventional monitoring systems, including complex ...

Impedance‐Matched High‐Overtone Thickness‐Shear Bulk Acoustic Resonators With Scalable Mode Volume
Advanced Science, EarlyView.A bottom‐electrode‐free high‐overtone bulk acoustic resonator is achieved by lateral excitation of antisymmetric thickness‐shear modes on a lithium‐niobate‐on‐silicon platform. Planar electrode geometry eliminates conventional loading along the resonance path and confines acoustic energy within the electrode gap.

A Machine Learning Based Approach for Available Bandwidth Estimation
, 2007 一條路徑的可用頻寬即為連結中最小未使用的頻寬。可用頻寬的估計對於許多應用程式是相當有用的，例如繞徑選擇，伺服器選擇，管理控制等等。近年來，許多用來改進可用頻寬估計的工具被提出。其中兩個非常受歡迎的模型分別是探查缺口模型和探查速率模型。因為利用這兩個模型的工具已經變得成熟，我們把這兩個模型與統計方法結合起來，並提出一個工具。 我們工具的基本想法是我們能在不同的可用頻寬下收集許多不同的資料。 在收集足夠的資訊之後，我們使用統計方法分析這些數據，並且使用其結果估計可用頻寬。在我們的模擬過程中 ...

Advanced Science, EarlyView.Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.
