We investigate the THz response of human brain tissue exhibiting Alzheimer's disease. Amyloid plaque buildup, believed to be a possible cause of this disease, is typically diagnosed by immunohistochemical inspection of beta-amyloid in ex vivo biopsy specimens. Using a broadband THz time domain spectrometer system in reflection mode imaging, we demonstrate the possibility of discriminating between...
MIMO antenna concepts for electronic eyewear devices operating in 4G cellular standard are proposed in this paper. Coupling element type antennas and matching circuits are used to obtain a high bandwidth potential for the coverage of the 700–960MHz and 1.7–2.7GHz frequency bands. To obtain a dual-antenna MIMO configuration, two CE type antennas are placed on the two sides of the head, resulting in...
The calculation of electron-phonon interaction from first principles has recently become feasible using density-functional perturbation theory (Quantum Espresso) [1] and the small displacement method (GPAW) [2]. We determine the strength of the electron-phonon interaction using the Vienna Ab-Initio Simulation Program (VASP) [3] with the small displacement method using PHONOPY [4]. We illustrate our...
Islanded operation of power systems with a shortage of generation to meet the local demand may experience a dip in frequency which could potentially damage the system equipment unless proper action is taken to shed loads in a timely manner. Recent research has shown that the uncertainty associated with estimating the amount of load to be shed can be better handled by fuzzy systems; however, there...
There are some different traits about the collaborative technological innovation between the core enterprise and general partner among the technological alliance. Based on the Ngo et al (2008), this paper analyzes the innovation cost, the competition level and the co-opetitive relationships from Stackelberg game theoretical approach, and comes to the following conclusions: when the core enterprise...
Pulse-modulated RF atmospheric pressure discharges were investigated in recent years to reduce the thermal accumulation of the discharge and extend the operation region of the stable apha glow mode. Different pulse-voltage and current waveforms were acquired in previous experiments, but no attention was paid to the interpretation. We investigated this issue by the aid of positive and negative feedback...
How to detect the outlier of stock prices effectively has become an intense concern of scholars in many fields. In this paper, the thoughts of Statistical theory and local density are introduced for researching the outliers in stock time series. A method detecting the outlier of stock time series based on density is proposed. Study on the outlier of time series in stock market is dealt with in two...
A new fault location algorithm for EHVAC mixed cable-overhead line based on fault zone identification is proposed. When the failure happened, first, according to the uniform transmission line equations, taking cable-overhead line connection point as reference, this article puts forward the fault zone identification method; then, deducts fault point positioning functions in different sections and gets...
We applied computerized methods to assess the Electronic Fetal Monitoring (EFM) in labor. We analyzed retrospectively the last hour of EFM for 1,370 babies, delivered by emergency Cesarean sections before the onset of pushing (data collected at the John Radcliffe Hospital, Oxford, UK). There were two cohorts according to the reason for intervention: (a) fetal distress, n1 = 524 and (b) failure to...
