Abstract Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents the holy grail human everlasting pursue ultra-fast information transmission and processing as well ultra-intense energy concentration extraction. It also holds key to unlock new extraordinary fundamental physical effects. Traditionally, spatiotemporal pulses are always treated spatiotemporally...

To compare the chemical differences between the medicinal and cultured oyster shells, their chemical profiles were investigated. Using the ultra performance liquid chromatography-electron spraying ionization-mass spectrometry (UPLC-ESI-MS), combined with principal component analysis (PCA) and orthogonal projection to latent structures discriminant analysis (OPLS-DA), the discrimination of the c...

This paper introduces the use of machine learning to improve efficiency of ultra-low-power sensor interfaces. Adaptive feature extraction circuits are assisted by hardware embedded learning to dynamically activate only most relevant features. This selection is done in a context and power cost-aware way, through modification of the C4.5 algorithm. Furthermore, context dependence of different fea...

We present a parameter extraction technique for higher-order transport models for a 2D electron gas in ultra thin body SOI MOSFETs. To describe 2D carrier transport we have developed a self consistent Schrödinger-Poisson Subband Monte Carlo simulator. The method takes into account quantization effects and a non equilibrium distribution function of the carrier gas, which allows an accurate descr...

Abstract Chinese jujube is a delicious fruit with high antioxidant nutrients. The peel, however, always discarded due to its indigestibility. In the current study, peels were collected for red pigment extraction. Six extraction-related parameters (ethanol concentration, solid-liquid ratio, material granularity, enzyme enzymolysis time, and pH) optimized peel extraction using Plackett–Burman Box...

Cancer classification is one major application of microarray data analysis. Due to the ultra high dimensionality nature of microarray data, data dimension reduction has drawn special attention for such type of data analysis. The currently available data dimension reduction methods are either supervised, where data need to be labeled, or computational complex. In this paper, we proposed to use a...

Pregabalin is an antiepileptic and analgesic drug, commercialized under the name of Lyrica, and generally used to treat neuropathic pain. The determination of pregabalin was performed by using spiked hair samples extracted in methanol and analyzed by ultra-high-performance liquid chromatography coupled with tandem mass spectrometry. The validation of a quantification method of pregabalin in hai...

سابقه و هدف: اگر چه ارتودنتیست ها مدتهاست بر این باورند که extraction دندان های پرمولر اغلب با ایجاد تغییراتی در نیمرخ بافت نرم همراه است اما تحقیقات بر این دلالت دارند که بافت نرم همواره به رترکشن بافت سخت به طور مطلوب پاسخ نمی دهد. این مطالعه با هدف تعیین رابطه بین درمان های non extraction (non-ext) و extraction (ext) دندان های پرمولر با تغییرات عمق انحنای لب ها در بیماران ارتودنتیک borderlin...
