Recent music information retrieval (MIR) research pays increasing attention to music classification based on moods expressed by music pieces. The first Audio Mood Classification (AMC) evaluation task was held in the 2007 running of the Music Information Retrieval Evaluation eXchange (MIREX). This paper describes important issues in setting up the task, including dataset construction and ground-...
A robust adaptive microphone array (RAMA) using a new adaptationmode control method (AMC) is proposed, and its evaluation results by hardware are presented. The adaptation of the RAMA is controlled based on an SNR (signal-to-noise) estimate using the output powers of the fixed beamformer and the adaptive blocking matrix. The RAMA is implemented on a multi-DSP realtime signalprocessing system wi...
In this work, we consider transmissions over block fading channels and assume that adaptive modulation and coding (AMC) and hybrid automatic repeat request (HARQ) are implemented. Knowing that in high signal-to-noise ratio, the conventional combination of HARQ with AMC is counterproductive from the throughput point of view, we adopt the so-called layer-coded HARQ (L-HARQ). L-HARQ allows consecu...

Introduction: Nitric oxide (NO) is a second messenger that regulates neurotransmitter release at the neuromuscular junction (nmj). Evidences accumulate on its potency as a neuro-modulator in CNS, PNS. This work investigates the effect of NO on (nmj) by adding L-arginine known as NO donor. Material and Methods: 30 albino rats’ diaphragms divided into two groups. Both exposed to L-argnine followe...
Adaptive modulation and coding (AMC) is a powerful technique to enhance the link performance by adjusting the transmission power, channel coding rates and modulation levels according to channel state information. In order to efficiently utilize the AMC scheme, an accurate signalto-noise ratio (SNR) value is normally required for determining the AMC level. In this paper, we propose an efficient ...
In this paper, the iterative Vertical-Bell-lab Layered Space-Time (V-BLAST) decoding algorithm of an Adaptive Modulation and Coding (AMC) system is proposed, and the corresponding MIMO scheme is analyzed. The proposed decoding algorithm adopts iteratively extrinsic information from a Maximum A Posteriori (MAP) decoder as an a priori probability in the two decoding procedures of the V-BLAST sche...
In this study, a Fe-based amorphous metallic coating (AMC) was sealed with three sealants, i.e., stearic acid, aluminum phosphate and cerium salt, respectively. Two types of electrochemical tests, namely the ex situ impedance spectroscopy test in potentiostatic polarization test, were conducted to evaluate erosion–corrosion resistance as-sprayed as-sealed AMCs. The results show that phosphate–s...
Biomineralisation, the deposition of mineral onto a matrix, can be both physiological and pathological process. Bone formation involves secretion an extracellular matrix (ECM) by osteoblasts subsequent mineralisation that matrix. It is regulated number local systemic factors necessary for maintenance normal bone health. Conversely, (or calcification) soft tissues, including vasculature, detrime...
The neutrophil/lymphocyte ratio (NLR), lymphocyte/ monocyte ratio (LMR), and absolute lymphocyte count/absolute monocyte count prognostic score (ALC/AMC PS) have been described as the most useful prognostic tools for patients with diffuse large B-cell lymphoma (DLBCL). We retrospectively analyzed 148 Taiwanese patients with newly diagnosed diffuse large B-cell lymphoma under rituximab (R)-CHOP-...
