    Impact and compensation of sample clock offset in I-CFDMA uplink by Dan DING, Nai-ping CHENG, Yu-rong LIAO

    Published 2015-10-01
    “…To achieve the sample clock synchronization in the interleaved code and frequency division multiple access(I-CFDMA)uplink,the I-CFDMA uplink model was established,and the disturbance of the sample clock offset(SCO)on the system model was discussed,in addition,the signal time shift,phase rotation,multi-user interference(MUI)and inter-carrier interference(ICI)caused by SCO were analyzed quantitatively.On this basis,a compensation method of multi-user SCO was proposed.For one thing,the relevant metric function was modified considering the SCO of each user; for another thing,a multi-user detection(MUD)algorithm based on harmony search was proposed.This algorithm has a higher efficiency than the commonly-used genetic algorithm(GA),as well as a performance approximate to that of optimal detection without SCO but with <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>1</mn> <mrow> <mn>64</mn></mrow> </mfrac> </math></inline-formula> computational burden.The computer simulation results validate the conclusions obtained.…”

    YOLO-LPSS: A Lightweight and Precise Detection Model for Small Sea Ships by Liran Shen, Tianchun Gao, Qingbo Yin

    Published 2025-05-01
    “…We propose YOLO-LPSS, a novel model designed to significantly improve small ship detection accuracy with low computation cost. The characteristics of YOLO-LPSS are as follows: (1) Strengthening the backbone’s ability to extract and emphasize features relevant to small ship objects, particularly in semantic-rich layers. (2) A sophisticated, learnable method for up-sampling processes is employed, taking into account both deep image information and semantic information. (3) Introducing a post-processing mechanism in the final output of the resampling process to restore the missing local region features in the high-resolution feature map and capture the global-dependence features. …”

    Diagnostic utility of auramine O smear microscopy for the detection of non-tuberculous mycobacteria vs Mycobacterium tuberculosis complex in adult clinical samples: a 3-year retrospective cohort study (2019-2021) by Dr Leong Tung Ong, Dr Azwani Abdullah, Dr Thian Chee Loh, Dr Chandramathi Samudi Raju, Ms Jennifer Chong, Dr Nadia Atiya

    Published 2025-03-01
    “…The sensitivity, specificity, PPV and NPV of auramine O smear microscopy for detecting NTM vs MTBC were 3.8% (95% CI 2.7-5.3) vs 52.2% (95% CI 48.6-55.8), 92.2% (95% CI 91.5-92.9) vs 99% (95% CI 98.7-99.2), 7.2% (95% CI 5.1-10) vs 87.7% (95% CI 84.3-90.5) and 85.7% (95% CI 84.8-86.6) vs 93.7% (95% CI 93.1-94.4) Discussion: Auramine O smear microscopy demonstrated low sensitivity and a low PPV (<90%) but high specificity (≥90%) for the detection of NTM and MTBC in clinical samples. …”
