INTRODUCTION To investigate the state of the art of intra-laboratory turnaround time (intra-TAT), provide suggestions and find out whether laboratories accredited by International Organization for Standardization (ISO) 15189 or College of American Pathologists (CAP) will show better performance on intra-TAT than non-accredited ones. MATERIALS AND METHODS(More)
INTRODUCTION Prenatal screening and diagnosis is important for the detection of birth defects and genetic diseases. The nationwide proficiency testing (PT) of maternal serum prenatal screening in second trimester in China has been launched since 2003 and partly reflected the performance of screening laboratories. This study analysed the 2015 PT results to(More)
In this paper, we propose a transmit signal pulse shaping approach to improve the data rates for the 3-user single-input-single-output interference channel (SISO-IC). The proposed scheme makes use of partial interference alignment based on suitable pulse shape design and no channel state information (CSI) at the transmitters, i.e., the transmitters are(More)
—A new 4 × 1 scheme of transmitting two real orthogonal space-time block codes (O-STBC) on the I-and Q-channels with pulse-shaped offset QAM is proposed. This scheme achieves full rate and employs simple real-symbol-wise decoding. Two families of pulse shapes for the offset QAM signal are considered: i) pulse shapes with zero cross-channel interference(More)
The complicated and changeable underwater environment increases the difficulty of pattern recognition for robotic fish swimming gaits. Aiming at this question, environment sensing and pattern recognition using an artificial lateral system are investigated in this work. Imitating lateral line of real fish in nature, a novel artificial lateral line system for(More)
BACKGROUND Clinical laboratory tests are important for clinicians to make diagnostic decisions, but discrepancies may directly lead to incorrect diagnosis. We would like to introduce some statistical methods to evaluate the comparability of chemistry analytes while comparing the performances of different measurement systems. METHODS We used a panel of 10(More)
