The bandgap reference circuits are very sensitive to electromagnetic interferences (EMI) which induce voltage offset on their outputs. Two bandgap chips with different technologies are designed for EMC study. The conducted immunity of VDD and VSS pins are tested following direct power injection (DPI) method. The aim of this study is to compare the susceptibility characteristics of same bandgap circuit...
Infrared neural stimulation (INS) provides a contact free, high spatial resolution method to regulate neural activities. Due to photothermal effect, neurons which located in the beam path, could be depolarized by infrared light. How to keep the high efficiency of opto-thermal transduction in nerve tissue, and meanwhile increase the photon penetration depth in untargeted tissues is the key question...
This paper states that Fitting Green's function Fast Fourier Transformation (FG-FFT) algorithm applies to accelerating matrix vector product of higher order Method of Moments (MoM). For different patch, the local expansion box is employed with the same expansion order of every Gaussian point. Combined the high accuracy of the FG-FFT with this scheme, it makes the FG-FFT very suitable for high order...
A criterion to describe the turn-to-turn discharge of the secondary winding in Tesla transformers is presented. Factors which have influences on the turn-to-turn insulation of the winding such as the wire diameter, the wire distance, the void size, the purity of transformer oil and the insulation strength of the wire are researched based on this criterion. By theoretical calculation, the electric...
Through data-mining of material genome approach, perovskite-type BiFeO3-Bi(Zn1/2Ti1/2)O3-PbTiO3 and BiFeO3-Bi(Zn1/2Ti1/2)O3-BaTiO3 ternary solid solution were designed theoretically and demonstrated experimentally to be promising novel high temperature ferroelectric piezoceramic materials. Like the PZT system, they are potential alternatives of PbNb2O6 and Bi4Ti3O12-based piezoceramics for future...
Mandarin speech has four different tones and the coding mechanism underlying tone identification still remain unclear. Here in the inferior colliculus (IC) of anesthetized guinea pigs, we recorded single neuron activities to one word with four tones using tungsten electrode. Peri-stimulus time histograms (PSTHs) and inter-spike-interval (ISI) were used to evaluate the neural response. The results...
Infant crawling is part of normal human gross motor development, and a 4-beat gait that involves rhythmical flexion and extension of limbs and the underlying muscle co-activation of antagonist muscle around the joint. However, detection the co-activation pattern of antagonist muscle are sparse due to the general difficulty of measuring locomotion in human infants. In this paper, sEMG of antagonist...
Generating industrial production cell lines with high productivity is a labor-intensive process with a limited throughput. As part of this process, hundreds of clones are screened using immunoassay and cell count data in multiple plates and dilutions, significantly decreasing the throughput of this traditional method. To overcome these limitations we developed a new solution phase hybridization technique,...
A new algorithm, exemplar based Laplacian Discriminant Projection (ELDP), is proposed in this paper for supervised dimensionality reduction. ELDP aims at learning a linear transformation which is an extension of Linear Discriminant Analysis(LDA). Specifically, we define three scatter matrices using similarities based on representative exemplars which are found by affinity propagation clustering. After...
Muscle Co-activation (MCo) is the simultaneous muscular activation of agonist and antagonist muscle groups, which provides adequate joint stability, movement accuracy during movement. Infant crawling is an important stage of motor function development that manifests non-synchronization growth and development of upper and lower limbs due to the well-known gross motor development principle of head to...
To explore the penetration depth with short-wavelength infrared light, 980nm pulse infrared light was used to stimulate the primary motor cortex of rat. The heating model was created to simulate the temperature distribution for 1875nm and 980nm infrared neural stimulation. Post-stimulus time histogram was used to observe the neural response induced by Infrared neural stimulation on primary motor cortex...
To explore whether the short wavelength near infrared laser can stimulate the functional hair cells, pulsed laser with wavelength of 808-nm was used to stimulate guinea pigs cochlea. Compound action potential (CAP) and auditory brainstem responses (ABR) were recorded during the experiments. We successfully recorded photomechanical responses from normal hearing animals and demonstrated the responses...
We demonstrate passive mode-locking of a Nd:Sc0.2Y0.8SiO5 laser using a semiconductor saturable absorber mirror. The pulse train shows output power of 0.5 W and pulse duration of 3.5 ps at repetition rate of 118 MHz.
Recently, diode-pumped solid-state lasers based on disordered Nd-doped crystals have attracted significant attention. In mode-locked operation they have a potential to generate tunable laser radiation with pulse duration in sub-picosecond time scale as well as to emit muti-wavelength ultrashort pulses which makes them attractive as a source for terahertz generation [1]. Nowadays, the binary and ternary...
Manufacturing execution system (MES) is becoming more and more important nowadays and more and more manufacturing enterprises in China are adopting MES. Hence, to improve the success rate of MES implementation is critical for enterprise. However, the study of this topic is still at the nascent stage and many firms find it difficult to implement MES effectively, especially they cannot make sure the...
To explore the optical neural stimulation with visible light, 620-nm red light pulse emitted by LED was used to stimulate the left primary visual cortex of adult rat. The neural response in right primary visual cortex was recorded with a flexible microelectrode. By synchronized averaging the raw signal, optical evoked potentials (OEPs) were observed a negative wave and positive wave after optical...
In motor nerve conduction studies, important diagnostic information is provided by the late-wave responses, comprised of F-waves, A-waves, and repeaters. Late-waves in addition to contamination from power line interference and baseline disturbance, are of low amplitude and random in nature. This makes computer-based analysis of late-wave activity very challenging, especially the computer-based F-wave...
Multitendoned extrinsic muscles of the human hand can be divided into several neuromuscular compartments (NMCs), each of which contributes to the ability of human finger to produce independent finger movements or force. The aim of this study was to investigate the changes in the spatial activation of flexor digitorum superficialis (FDS) during the fingertip force production with non-invasive multichannel...
A working predictive schedule can be useless because of the various external or internal disruptions in a job shop. Total rescheduling may cause problems such as shop floor nervousness. Thus, the job shop scheduling repair (recovery) approach aims at generating a solution satisfying the updated constraints and making deviations minimized. We propose an incremental temporal reasoning approach in this...
For the everyday dispatching and commanding in the existing railway line in China, the accuracy of dispatching daily plan directly affects the whole efficiency of the dispatching and commanding system in the railway bureau. The planning process of daily dispatching plan is a complex cooperative process in which many participating roles are involved. Establishing the process model is helpful to reflect...
