The aberrant growth of head and neck squamous cell carcinoma (HNSCC) is often associated with the constitutive activation of signal-transducer-and-activator-of-transcription-3 (STAT3), which is believed to result from the persistent stimulation of EGF receptors that are highly expressed in squamous cell carcinoma (SCC) cells. To investigate the mechanism(More)
Accelerated degradation testing (ADT) expedites product degradation by stressing the product beyond its normal use. To extrapolate the product's reliability at use condition, the ADT requires a known functional link relating the harsh testing environment to the usual use environment. Practitioners are often faced with a great challenge to designate an(More)
The early detection of faulty batteries is a critical work in the manufacturing processes of a secondary rechargeable battery. Conventional approaches use original performance degradation profiles of remaining capacity after recharge in order to detect faulty batteries. However, original degradation profiles with right-truncated test duration may not be(More)
Defects generated during integrated circuit (IC) fabrication processes are classified into global defects and local defects according to their generation causes. Spatial patterns of locally clustered defects are likely to contain the information related to their defect generation mechanisms. In this paper, we propose a model-based clustering for spatial(More)
Near infrared (NIR) spectroscopy is a rapid, non-destructive technology to predict a variety of wood properties and provides great opportunities to optimize manufacturing processes through the realization of in-line assessment of forest products. In this paper, a novel multivariate regression procedure, the hybrid model of principal component regression(More)
PURPOSE Radiotherapy of the neck is known to cause carotid artery stenosis. We compared the carotid artery dose received between volumetric modulated arc therapy (VMAT) and conventional fixed-field intensity-modulated radiotherapy (IMRT) plans in patients with early glottic cancer. MATERIALS AND METHODS Twenty-one early glottic cancer patients who(More)
In this paper, we propose an optical orthogonal code (OOC) acquisition scheme for optical code division multiple access (CDMA) systems. By employing multiple thresholds, the proposed scheme provides a better mean acquisition time (MAT) performance than the conventional scheme. Numerical results demonstrate that the MAT of the proposed scheme is shorter than(More)
The time-consuming evaluation of a product’s lifetime or quality often prevents manufacturers from meeting market requirements within the time allotted for product development. Degradation profiles obtained from harsh testing environments have been widely used in many applications to shorten the evaluation time. In this paper, we propose a novel recursive(More)
