Reverse Weak Polarity‐Induced Ordered Layer Control for Enhanced Second‐Harmonic Generation in Ultraviolet Nonlinear Optical Crystals

open access: yesAdvanced Science, EarlyView.
Reverse Weak Polarity‐Induced Ordered Layer Control strategy, optimizing the design of layered structures, has been successfully designed. By leveraging inhomogeneous field of units to replace isotropic fields of metal cations, polar layers realize controllable layer stacking via a “layer→linker→layer” polarity transfer.

Novel Cancellation Techniques and Throughput Analysis for 6G Full-Duplex Wireless System

open access: yesSpace: Science & Technology
Recent researches show that it is possible to achieve full-duplex system if the self-interference signal could be cancelled completely for 6G research. The majority of the overall self-interference cancellation is contributed by passive cancellation. The

Performance on ICI Self-Cancellation in FFT-OFDM and DCT-OFDM System

open access: yesJournal of Function Spaces, 2015
In orthogonal frequency division multiplexing (OFDM) system, the existence of frequency offset in AWGN channel affects the orthogonality among the subcarriers and consequently introduces the intercarrier interference (ICI). The paper investigates new ICI

Multi-Carrier CDMA using Interference Cancellation

open access: yes, 2000
In this paper, various detection techniques in the synchronous case of a multi-user MC-CDMA system operating in frequency selective Rayleigh channel are compared with respect to the achievable spectral efficiency. It is shown that a parallel interference cancellation MMSE scheme with two stages could be a good compromise between performance and ...

Beyond the Ban—Shedding Light on Smallholders' Price Vulnerability in Indonesia's Palm Oil Industry

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Indonesian government imposed a palm oil export ban in April 2022 to address rising cooking oil prices. This study explores oil palm smallholders' vulnerability to the policy using descriptive statistics, Lasso, and post‐Lasso OLS regressions.

Performance Limitations Analysis of Imperfect Attenuators for Adaptive Self-Interference Cancellation System [PDF]

open access: yesRadioengineering, 2016
Radio frequency (RF) adaptive self-interference cancellation system (RFAICS) is extensively used to suppress the self-interference of radios operating in the same platform, such as military command vehicles, airplanes and navy vessels.

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

Compressive Domain Interference Cancellation

open access: yes, 2009
In this paper we consider the scenario where a compressive sensing system acquires a signal of interest corrupted by an interfering signal. Under mild sparsity and orthogonality conditions on the signal and interference, we demonstrate that it is possible to efficiently filter out the interference from the compressive measurements in a manner that ...

Interpretation of A Focus Shift From Sarcopenia to Muscle Health in the Asian Working Group for Sarcopenia 2025 Consensus Update

open access: yesAGING MEDICINE, EarlyView.
The AWGS 2025 consensus shifts focus from diagnosing sarcopenia to promoting muscle health across the lifespan. It simplifies diagnosis to low muscle mass plus low strength, expands screening to middle‐aged adults, and integrates muscle health into the WHO ICOPE framework for early intervention and healthy aging.
