Study on Interference-free Stereophonic Acoustic Echo Cancellation Algorithm

open access: yes工程科学与技术, 2007
:In order to solve misalignment problem in stereophonic acoustic echo cancellation (SAEC), a nonlinear preprocessing solution based on frequency-shifting was proposed to reduce the correlation between the stereo signals and improve misalignment. Because

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

open access: yesFlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Neoadjuvant Atezolizumab and Chemotherapy for Non‐Squamous Non‐Small Cell Lung Cancer: Efficacy and Safety Results of an Open‐Label, Single‐Arm, Phase II Trial

open access: yesInternational Journal of Cancer, EarlyView.
Surgery plus chemotherapy is a well‐established treatment protocol for resectable, locally advanced non‐small cell lung cancer (NSCLC). Nonetheless, survival gains remain limited, emphasizing the need for more effective treatments. Here, the authors evaluated a novel approach using a neoadjuvant immunotherapy‐chemotherapy regimen consisting of ...

Interference cancellation system

open access: yes, 2009
This thesis examines the problem of coupling of on-channel repeaters in a 3G wireless system. Unwanted feedback occurs between the donor and coverage antennas of a repeater. The unwanted feedback appears as radio echoes which creates interference in the incoming signal from the base station.

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...
