Modeling of vehicle trajectory clustering based on LCSS for traffic pattern extraction (2017)

The emerging of the intelligent transportation system especially in the research area of traffic surveillance and solving traffic congestions, become notably crucial for traffic operators in the aim of achieving efficient vehicle flow. However, behavioural manoeuvres that describe the pattern of vehicles movements and change of the vehicle flow are not sufficiently modeled based on the conventional inductive-loop traffic sensors. These behavioural manoeuvres are useful for interpreting the indepth study of traffic pattern in a traffic network. Hence, with the advancement of the available vehicle tracking system, vehicle trajectory dataset is selected as suitable candidate input for the traffic pattern extraction. The implementation of k-means and fuzzy c-means (FCM) clustering algorithm for vehicle flow analyzing task is served as focus in this paper. Similarity function based on Longest Common Subsequence (LCSS) is implemented to measure the similarity among the trajectories before clustering is performed. Rand Index (RI) is computed to evaluate the clustering performance of two sets trajectories with two different traffic scenes by comparing the simulated clustering result with the ground-truth result.
A 15nW standby power 64Kb CMOS RAM (1982)

A FULLY STATIC 8K x 8b CMOS RAM, with a six-transistor structure, an internally-clocked low-power circuit and a redundancy technique, together with double polysilicon CMOS processing will be covered. The RAM offers typically 15mW power dissipation at lMHz operation, 50nW for standby and 8011s typical access time. Recently, it has been realized that a resistive load NMOS cell with CMOS peripheral circuits can offer high density, high speed and low active power for static RAMs. However, even with an extremely high resistive load, standby power level is limited to around 25pW typically, for 16Kb integration1, while sacrificing process margin. On the other hand, a six-transistor CMOS memory cell can provide standby current three orders of magnitude smaller, while maintaining much wider temperature and voltage range as well as noise margin. Obviously, a penalty for the performance is larger cell area.
Gas Permeation Behavior of Pebax-1657 Nanocomposite Membrane Incorporated with Multiwalled Carbon Nanotubes (2010)

Incorporation of multiwalled carbon nanotubes (MWNT) on the gas permeation properties of H2, CO2, O2, and N2 gases in poly(ether-block-amide) (Pebax-1657) membrane has been investigated. Pebax-1657 was dissolved in the ethanol−water mixture and cast on an ultraporous polyethersulfone substrate followed by complete solvent evaporation. Nanocomposite membranes were prepared by dispersion of MWNT in concentrations of 0−5% of polymer weight in the Pebax solutions with sonication for 2 h to ensure uniformity. Cross-linking was carried out in hexane medium using 2,4-toluylene diisocyanate (TDI). The permeabilities of pure gases were measured at room temperature, and the ideal selectivities were determined at pressures varying from 1−3 MPa using an indigenously built high-pressure gas separation manifold. For neat Pebax membrane, high permeabilities of 55.8 and 32.1 barrers were observed for CO2 and H2 gases, respectively, whereas that of N2 was as low as 1.4 barrers. The selectivity of cross-linked 2% MWNT Pebax membrane was enhanced from 83.2 to 162 with increasing feed pressure (1−3 MPa) for the CO2/N2 gas pair, whereas the corresponding values for H2/N2 and O2/N2 systems were found to be in the range 82.5−90 and 7.1−6.8, respectively. The membranes were characterized by scanning electron microscopy (SEM) to study surface and cross-sectional morphologies. Fourier transform infrared (FT-IR), wide-angle X-ray diffraction (WAXD), and ion exchange capacity (IEC) studies were carried out to determine the effect of MWNT incorporation on intermolecular interactions, degree of crystallinity, and extent of cross-linking, respectively. Fractional free volume (FFV) calculations based on density measurements were conducted along with water sorption studies to explain permeation behavior. The use of modified block copolymer membranes provides a means for separation of CO2 from N2 in power plants, H2 recycle from ammonia purge gas, O2 enrichment from air for medical applications, and CO2 removal from water-gas shift reaction to improve H2 yield.
Implementation of reconfigurable software radio for multiple wireless standards 1,2 (2004)

The commercial success of personal wireless communications has resulted in a fast-paced technology and a proliferation of standards. We present a detailed description of a software reconfigurable radio that configures itself to demodulate one of multiple wireless PCS standard formats. One such PCS standard is IS-136, which has a carrier spacing of 30 kHz, operates in the 880-960 MHz band in the US and uses pi/4-DQPSK modulation. Another PCS standard is GSM, which occupies the 824-894 MHz band in Europe and uses GMSK modulation with a 200 kHz carrier. The software-based radio we describe can configure itself to the appropriate center frequency, bandwidth, and data rate of both standards. The design methodology for implementation and testing of a reconfigurable radio is reported.
Denaturing gradient gel electrophoresis and its use in the detection of major histocompatibility complex polymorphism (2005)

The major histocompatibility complex (MHC) has been studied extensively in humans and in mice and many methods are available for MHC typing of these well-characterized species. Studies of MHC variation in other species are ever increasing and researchers can choose one of a number of approaches for MHC typing of their species of interest. DNA sequencing is regarded as the 'gold standard' and it is frequently used for MHC typing. However, DNA sequencing is impractical when many individuals must be typed. Denaturing gradient gel electrophoresis (DGGE) offers a flexible and sensitive method for identifying and characterizing MHC alleles in any vertebrate species. This article reviews the theory and the practice of DGGE and examines the use of DGGE for MHC identification in various species. DGGE is compared to other similar techniques for MHC typing, such as single-stranded conformational polymorphism and reference strand-mediated conformational analysis. The advantages, problems, pitfalls and limitations of DGGE are considered and future perspectives on the use of DGGE for MHC typing are discussed.
Teratological effects of Western equine encephalitis virus on the fetal nervous system of <i>Macaca mulatta</i> (1982)

Fetal rhesus monkeys were inoculated intracerebrally with an attenuated strain of western equine encephalitis virus. All animals developed microcephaly. Twelve of sixteen monkeys developed ex vacuo hydrocephalus. All virus inoculated fetuses developed WEE virus antibody. Virus could not be recovered at the time of delivery. Monkeys with the highest WEE antibody titers showed the greatest degree of hydrocephalus.

The frequency domain method, non-uniform interpolation, POCS method, iterative back projection method, Bayesian approach, regularization method are both discussed for super-resolution image reconstruction.
Modulation of spin transfer torque amplitude in double barrier magnetic tunnel junctions (2015)

Magnetization switching induced by spin transfer torque is used to write magnetic memories (Magnetic Random Access Memory, MRAM) but can be detrimental to the reading process. It would be quite convenient therefore to modulate the efficiency of spin transfer torque. A solution is adding an extra degree of freedom by using double barrier magnetic tunnel junctions with two spin-polarizers, with controllable relative magnetic alignment. We demonstrate, for these structures, that the amplitude of in-plane spin transfer torque on the middle free layer can be efficiently tuned via the magnetic configuration of the electrodes. Using the proposed design could thus pave the way towards more reliable read/write schemes for MRAM. Moreover, our results suggest an intriguing effect associated with the out-of-plane (field-like) spin transfer torque, which has to be further investigated.
Biomedical Signal and Image Processing (2005)

ALPHA-IODIC ACID: A SOLUTION-GROWN CRYSTAL WITH A HIGH FIGURE OF MERIT FOR ACOUSTO-OPTIC DEVICE APPLICATIONS (1968)

The photoelastic properties of α-HIO3 have been measured and the applicability of the material for acousto-optic device applications determined. In the blue and green portions of the visible the material has the highest figure of merit, n6p2/ρv3, of any known crystal, approximately twelve times that of LiNbO3 and fifty times that of fused silica. Other desirable properties for these applications include (a) the availability of large solution-grown single crystals of high optical quality, (b) low acoustic and optic losses, and (c) the absence of ``optical damage.'' A simple acoustically driver beam deflector was also constructed to demonstrate the potential of this material. It was found that 70% of a 0.63-μ laser beam could be deflected, over a bandwidth of 55 MHz, with an electrical drive power of 265 mW, while 70% of a 0.488-μ laser beam could be deflected over the same bandwidth with 94 mW of electrical power.
The Improvement of Learning and Memory Ability of Normal Persons by BF-7 (2004)

【To investigate whether BF-7, extracted from Bombyx mori, improved learning and memory of ordinary people, Rey-Kim Memory Test was performed with placebo group (32 persons), 200 mg BF-7 treated group (33 persons) and 400 mg BF-7 treated group (34 persons). BF-7 enhanced significantly learning and memory function in a dose-dependent manner. To know how BF-T plays such a positive role, we measured the concentration of acetylcholine in the brain from memory impairment animal model. Treatment of BF-7 significantly increased the concentration of acetylcholine. So, it is supposed that the protection of cholinergic neuron and/or keeping proper concentration of acetylcholine might be one of the mechanisms by which BF-7 improve brain function. So, our results suggest that the BF-7 is effective material for improving learning and memory ability.】
Amyloid β-related central nervous system vasculitis (2016)

Amyloid β (Aβ)-related central nervous system (CNS) vasculitis, which is also known as cerebral amyloid angiopathy (CAA)-related CNS vasculitis, is characterized by the presence of chronic inflammation within or around the walls of Aβ-deposit blood vessels. Cerebral biopsy is the gold standard for diagnosis of A β-related CNS vasculitis considering the atypical clinical features, cerebrospinal fluid (CSF) and neuroimaging findings of some patients. This paper reviewed the pathogenesis, neuropathology, clinical features, treatment and prognosis of Aβ-related CNS vasculitis. DOI: 10.3969/j.issn.1672-6731.2016.01.002
Effects of water vapor anneal on MIS devices made of nitrided gate dielectrics (2002)

Silicon nitride and oxynitride films are known to possess a number of attractive properties over thermal SiO/sub 2/ as gate dielectric for Field-Effect Transistors (FETs), including better resistance to impurity diffusion and higher dielectric constant. However, their poor interface properties have prevented their use as a mainstream gate dielectric. Even in the case of nitrodized oxides where the nitrogen content is minute, the reduced peak transconductance for n-channel transistors is still a major concern for many applications, despite their much improved reliability. This paper shows that a modest annealing treatment in a steam furnace yields dramatic improvement of FET's transconductance as well as its current driveability for devices containing nitrided gate while preserving their excellent reliability. Only results on silicon nitride based MNS devices are included.
Supercritical Gas Extraction of Alkanes and Alkanoic Acids from Soils and Humic Materials (1986)

Abstract Three soils and two humic materials were extracted with n ‐pentane by supercritical gas extraction. The extracts contained a variety of compounds separated by chemical and gas chromatographic techniques and identified by gas chromatography‐mass spectrometry. The compounds identified in the extracts included n ‐alkanes (ranging from n ‐C 12 to n ‐C 32 ), with n ‐C 26 , and n ‐C 24 alkanes in prominence, and smaller amounts of cyclic alkanes (C 19 to C 31 ). The major components, however were n ‐fatty acids ( n ‐C 7 to n ‐C 29 ), accompanied by lesser amounts of branched fatty acids (C 12 to C 19 ), and unsaturated fatty acids ( n ‐C ‐ 16 , n ‐C ‐ 18 and n ‐C ‐ 18 ). hydroxy‐fatty acids (C 12 to C 16 ), and alkanoic α,ω‐diacids (C 15 ‐C 25 ). The overall even‐to‐odd preference indexes for the n ‐alkanes and n ‐fatty acids were 1.35 and 4.15, respectively, suggesting microbiological origins for these compounds. Total alkanes extracted from the soils and humic preparations ranged from 4.3 to 8.9 and 32.5 to 201.4 mg/kg, respectively. By contrast, alkanoic acids extracted varied from 94.5 to 208.9 mg/kg for the soils and 740.1 to 1576.6 mg/kg for the humic materials. Supercritical gas extraction appears to be a promising procedure for the relatively mild and efficient extraction of specific organic components from soils and humic materials.
Novel plasma membrane action of estrogen and antiestrogens revealed by their regulation of a large conductance chloride channel (1994)

Antiestrogens antagonize many genomic effects of estrogen through binding to the nuclear estrogen receptor. We report here that NIH3T3 fibroblasts grown in the presence of colchicine acquire the activation of a large conductance chloride channel upon exposure to extracellular but not intracellular antiestrogens. This effect can be prevented by extracellular 17 beta-estradiol, but not intracellular 17 beta-estradiol or extracellular 17 alpha-estradiol. This is the first demonstration of a regulatory role for antiestrogens and estrogens in the regulation of ionic channels occurring through an interaction of these compounds with a plasma membrane binding site distinct from the classical estrogen receptor and subsequent activation of intracellular second messenger pathway (or pathways).
Mitochondria and Antioxidant Targeted Therapeutic Strategies for Alzheimer's Disease (2010)

Oxidative stress and mitochondrial dysfunction are important features present in Alzheimer's disease (AD). They appear early and contribute to disease progression, both in human postmortem AD brains as well as in transgenic AD mouse brains. For this reason, targeting oxidative stress and mitochondria in AD may lead to the development of promising therapeutic strategies. Several exogenous antioxidant compounds have been tested and found beneficial in transgenic AD mice, such as vitamins and spices. However, their efficacy was much more modest in human trials. More recently, new strategies have been elaborated to promote endogenous antioxidant systems. Different pathways involved in oxidative stress response have been identified. Compounds able to upregulate these pathways are being generated and tested in animal models of AD and in human patients. Upregulation of antioxidant gene expression was beneficial in mice, giving hope for future avenues in the treatment of AD and other neurodegenerative disorders.

Protective effects of<i>Lactobacillus plantarum</i>against epithelial barrier dysfunction of human colon cell line NCM460 (2010)

L. plantarum can protect against dysfunction of NCM460 intestinal epithelial barrier caused by enteropathogenic E. coli or enteroinvasive E. coli, and thus can be a potential candidate of therapeutic agents for the treatment of intestinal diseases.
A neural network which learns decision boundaries with nonlinear clustering (1991)

Presents a novel neural network which works as a classifier. It uses Euclidean distance similarity measurement to form clusters which are represented by output units. Uniquely, output units in the proposed network have nonlinear hard-limiter activation functions. Through this nonlinear activation function, complex decision boundaries from input patterns can be approximated. Furthermore, it does not forget previously remembered training patterns as it remembers newly shown patterns. This is shown with illustrative proofs. Simulation results are presented and compared with those from the backpropagation neural network. They demonstrate that the network described, with its simple architecture and learning, it is able to capture continuous distributions of complex decision boundaries from discrete patterns.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<i>In vitro</i> and <i>in vivo</i> antimalarial activity of cryptolepine, a plant‐derived indoloquinoline (1995)

Abstract Cryptolepine is an indoloquinoline, high yields of which may be extracted from the roots of the West African shrub Cryptolepis sanguinolenta. The use of this plant as a traditional treatment for malaria is widespread in Ghana and is reported to be clinically effective. We have tested cryptolepine for in vitro antiplasmodial activity against the multidrug resistant (K1) strain of Plasmodium falciparum and found it to be highly active with an IC 50 value of 0.031±0.0085 (SE) μg/mL, equivalent to 0.134±0.037 μM ( n = 3). In a 4‐day suppression test there was, however, no significant reduction in parasitaemia in P. berghei ‐infected mice treated subcutaneously with cryptolepine (7–113 mg/kg/d×4), when compared with untreated controls. Like 9‐aminoacridine, this compound appears to intercalate with DNA and this may explain the high degree of antimalarial activity demonstrated in vitro .
Progress on Ceramic Rotor Blade Development for Industrial Gas Turbines (1978)

This paper reviews progress made in the first year of a three-year program sponsored by EPRI to design and test ceramic root attachments, leading to the full development of ceramic rotor blades and cantilevered vanes intended for industrial gas turbines. Initial work has focused on a rotor blade attachment design. The specific rotor configuration chosen for development consists of a cooled low-alloy steel disk, a cooled intermediate super-alloy attachment piece, an uncooled ceramic blade, and the provision for a compliant interface at the ceramic/metal root attachment. A new root attachment design, in which the root and groove are curved in their transverse and longitudinal directions, is presented. Room temperature spin tests of dovetail root forms have provided encouraging results and indicate that continued development is warranted.
Single-crystalline Silicon on Quartz (SOQ) Wafer by Ultra-low Temperature (100 C) Wafer Bonding and Thinning Approaches (2005)

Single-crystalline silicon films have been prepared on synthetic quartz (fused quartz or quartz glass) substrates by ultra-low temperature wafer bonding and thinning approaches. The wafer surfaces treated only by RCA1 process showed a relative low initial bonding energy of 0.17 J/m 2 . Though the bonding strength can be raised to 14 J/m 2 after 350 C annealing for 4 h, the severe warpage of bonded wafer led to the poor total thickness variation (TTV) of SOQ wafers (TTV > 10 m) after thinning. However, if the wafer surfaces treated with RCA1 process, and followed by O2 plasma treatment for 15 sec, the initial bonding energy can be raised to 0.83 J/m 2 . After the bonded wafer annealed at 100C for 16 hrs, the bonding strength increased rapidly to 13.3 J/m 2 with still a low warpage of 2.5 m. The SOQ wafers fabricated by the ultra-low temperature bonding, lapping and polishing showed relative good TTV of less than 4 m.

Power system steady-state stability and the load-flow Jacobian (1990)

The relationship is presented between a detailed power system dynamic model and a standard load-flow model. The linearized dynamic model is examined to show how the load-flow Jacobian appears in the system dynamic-state Jacobian for evaluating steady-state stability. Two special cases are given for the situation when singularity of the load-flow Jacobian implies singularity of the system dynamic-state Jacobian. The standard load-flow Jacobian can provide information about the existence of a steady-state equilibrium point for a specified level of loading or interchange. There are two very special cases when the determinant of the standard load-flow Jacobian implies something about the steady-state stability of a dynamic model. Both of these cases involve very drastic assumptions about the synchronous machines and their control systems. The load level which produces a singular load-flow Jacobian should be considered an optimistic upper bound on maximum loadability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of Monospecies Biofilm Formation by <i>Helicobacter pylori</i> (2004)

ABSTRACT As all bacteria studied to date, the gastric pathogen Helicobacter pylori has an alternate lifestyle as a biofilm. H. pylori forms biofilms on glass surfaces at the air-liquid interface in stationary or shaking batch cultures. By light microscopy, we have observed attachment of individual, spiral H. pylori to glass surfaces, followed by division to form microcolonies, merging of individual microcolonies, and growth in the third dimension. Scanning electron micrographs showed H. pylori arranged in a matrix on the glass with channels for nutrient flow, typical of other bacterial biofilms. To understand the importance of biofilms to the H. pylori life cycle, we tested the effect of mucin on biofilm formation. Our results showed that 10% mucin greatly increased the number of planktonic H. pylori while not affecting biofilm bacteria, resulting in a decline in percent adherence to the glass. This suggests that in the mucus-rich stomach, H. pylori planktonic growth is favored over biofilm formation. We also investigated the effect of specific mutations in several genes, including the quorum-sensing gene, luxS , and the cagE type IV secretion gene. Both of these mutants were found to form biofilms approximately twofold more efficiently than the wild type in both assays. These results indicate the relative importance of these genes to the production of biofilms by H. pylori and the selective enhancement of planktonic growth in the presence of gastric mucin.
Therhionic Integrated Circuits: Electronics for Hostile Environments (1985)

Thermionic integrated circuits (TICs) combine thermionic emission of vacuum tube technology with the thin-film deposition and photolithographic delineation techniques of conventional silicon integrated circuits to form microminiature-integrated vacuum triode circuits. The resulting integrated circuits are extremely tolerant to both high-radiation and high-temperature environments.
