Analysis of infinite arrays of one- and two-probe-fed circular patches (1990)

An analysis is presented of the radiation properties of infinite phased arrays of one- or two-probe-fed circular microstrip patches, using a rigorous Green's-function/moment-method approach. Two ways of treating the connection of a vertical feed probe to the patch are considered: an idealized probe feed model, which is useful for antennas printed on thin substrates or to predict general performance trends, and a more rigorous treatment that overcomes the deficiencies of the simpler model. This rigorous treatment seems to have some advantages over other published analyses, including applicability to a wide range of printed radiator problems, but requires a huge increase in the amount of computer time required for the calculation. Comparisons of both feed models with measured data from waveguide simulators are used to validate the theory for both one- and two-probe-fed elements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The Potential Role of the cABR in Assessment and Management of Hearing Impairment (2013)

Hearing aid technology has improved dramatically in the last decade, especially in the ability to adaptively respond to dynamic aspects of background noise. Despite these advancements, however, hearing aid users continue to report difficulty hearing in background noise and having trouble adjusting to amplified sound quality. These difficulties may arise in part from current approaches to hearing aid fittings, which largely focus on increased audibility and management of environmental noise. These approaches do not take into account the fact that sound is processed all along the auditory system from the cochlea to the auditory cortex. Older adults represent the largest group of hearing aid wearers; yet older adults are known to have deficits in temporal resolution in the central auditory system. Here we review evidence that supports the use of the auditory brainstem response to complex sounds (cABR) in the assessment of hearing-in-noise difficulties and auditory training efficacy in older adults.
Projecting sensations to external objects: evidence from skin conductance response (2003)

Subjects perceived touch sensations as arising from a table (or a rubber hand) when both the table (or the rubber hand) and their own real hand were repeatedly tapped and stroked in synchrony with the real hand hidden from view. If the table or rubber hand was then 'injured', subjects displayed a strong skin conductance response (SCR) even though nothing was done to the real hand. Sensations could even be projected to anatomically impossible locations. The illusion was much less vivid, as indicated by subjective reports and SCR, if the real hand was simultaneously visible during stroking, or if the real hand was hidden but touched asynchronously. The fact that the illusion could be significantly diminished when the real hand was simultaneously visible suggests that the illusion and associated SCRs were due to perceptual assimilation of the table (or rubber hand) into one's body image rather than associative conditioning. These experiments demonstrate the malleability of body image and the brain's remarkable capacity for detecting statistical correlations in the sensory input.
Highly Ordered Mesoporous Carbon Synthesized via in Situ Template for Supercapacitors (2009)

An in-situ silica template method has been employed to prepare mesoporous carbon materials. As-prepared carbon materials have been characterized by transmission electron microscopy, small-angle X-ray diffraction, N2 adsorption-desorption, Fourier transform infrared spectroscopy and electrochemical techniques. The results reveal that highly ordered mesoporous carbon with abundant hydrophilic functional groups and high specific surface area (1628 m2 g-1) was obtained. Such material has high specific capacitance (161 F g-1) and the capacitance shows negligible dependence on the potential sweep rate, which makes it promising in supercapacitor application.
UWB Noise-OFDM Netted Radar: Physical Layer Design and Analysis (2011)

It is well known that ultra-wideband (UWB) noise radar achieves high-resolution imaging of targets and terrain. The wide bandwidth yields fine range resolution, while the noise waveform provides immunity from detection, interference, and interception. Having multiple noise radars networked with each other provides significant benefits in target detection and recognition. We propose a scheme to modify the UWB noise radar to supplement it with secure multi-user network communication capabilities, thus architecting the UWB noise-orthogonal frequency-division multiplexing (OFDM) netted radar. The salient features of this multi-functional radar system include surveillance with embedded security-enabled OFDM-based communications, multi-user capability, and physical layer security. The system's physical layer design is analyzed for the composite UWB noise-OFDM waveform's dual performance, communications reliability, confidentiality, and message integrity protection. We also present critical issues that underscore the need for a unique medium access control (MAC) algorithm as a duplex multiplexing technique for this ad hoc multi-radar communications network.
Cartilage stem/progenitor cells are activated in osteoarthritis via interleukin-1β/nerve growth factor signaling (2015)

Our results strongly suggest that NGF signaling is a contributing factor in articular cartilage degeneration in OA, which likely targets a specific subpopulation of progenitor cells, the CSPCs, affecting their migratory and matrix remodeling activities. These findings provide novel cellular/signaling therapeutic targets in osteoarthritic cartilage.
An On-Chip CMOS Relaxation Oscillator With Voltage Averaging Feedback (2010)

An on-chip CMOS relaxation oscillator with voltage averaging feedback using a reference proportional to supply voltage is presented. A voltage-averaging feedback (VAF) concept is proposed to overcome conventional relaxation oscillator problems such as sensitivity to comparator delay, aging, and flicker noise of current sources. A test-chip with typical frequency of 14.0 MHz was fabricated in a 0.18 μm standard CMOS process and measured frequency variations of ±0.16 % for supply changes from 1.7 to 1.9 V and ±0.19% for temperature changes from -40 to 125°C. The prototype draws 25 μA from a 1.8 V supply, occupies 0.04 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , and achieves 7x reduction in accumulated jitter (at 1500th cycle) as compared to a oscillator without VAF.
CMAR: accurate and efficient classification based on multiple class-association rules (2002)

Previous studies propose that associative classification has high classification accuracy and strong flexibility at handling unstructured data. However, it still suffers from the huge set of mined rules and sometimes biased classification or overfitting since the classification is based on only a single high-confidence rule. The authors propose a new associative classification method, CMAR, i.e., Classification based on Multiple Association Rules. The method extends an efficient frequent pattern mining method, FP-growth, constructs a class distribution-associated FP-tree, and mines large databases efficiently. Moreover, it applies a CR-tree structure to store and retrieve mined association rules efficiently, and prunes rules effectively based on confidence, correlation and database coverage. The classification is performed based on a weighted /spl chi//sup 2/ analysis using multiple strong association rules. Our extensive experiments on 26 databases from the UCI machine learning database repository show that CMAR is consistent, highly effective at classification of various kinds of databases and has better average classification accuracy in comparison with CBA and C4.5. Moreover, our performance study shows that the method is highly efficient and scalable in comparison with other reported associative classification methods.
<i>Slc25a13</i>-Knockout Mice Harbor Metabolic Deficits but Fail To Display Hallmarks of Adult-Onset Type II Citrullinemia (2003)

Adult-onset type II citrullinemia (CTLN2) is an autosomal recessive disease caused by mutations in SLC25A13, the gene encoding the mitochondrial aspartate/glutamate carrier citrin. The absence of citrin leads to a liver-specific, quantitative decrease of argininosuccinate synthetase (ASS), causing hyperammonemia and citrullinemia. To investigate the physiological role of citrin and the development of CTLN2, an Slc25a13-knockout (also known as Ctrn-deficient) mouse model was created. The resulting Ctrn-/- mice were devoid of Slc25a13 mRNA and citrin protein. Liver mitochondrial assays revealed markedly decreased activities in aspartate transport and the malate-aspartate shuttle. Liver perfusion also demonstrated deficits in ureogenesis from ammonia, gluconeogenesis from lactate, and an increase in the lactate-to-pyruvate ratio within hepatocytes. Surprisingly, Ctrn-/- mice up to 1 year of age failed to show CTLN2-like symptoms due to normal hepatic ASS activity. Serological measures of glucose, amino acid, and ammonia metabolism also showed no significant alterations. Nitrogen-loading treatments produced only minor changes in the hepatic ammonia and amino acid levels. These results suggest that citrin deficiency alone may not be sufficient to produce a CTLN2-like phenotype in mice. These observations are compatible, however, with the variable age of onset, incomplete penetrance, and strong ethnic bias seen in CTLN2 where additional environmental and/or genetic triggers are now suspected.
Methods for genome-wide DNA methylation analysis in human cancer (2016)

Aberrant DNA methylation is considered to be one of the most common hallmarks of cancer. Several recent advances in assessing the DNA methylome provide great promise for deciphering the cancer-specific DNA methylation patterns. Herein, we present the current key technologies used to detect high-throughput genome-wide DNA methylation, and the available cancer-associated methylation databases. Additionally, we focus on the computational methods for preprocessing, analyzing and interpreting the cancer methylome data. It not only discusses the challenges of the differentially methylated region calling and the prediction model construction but also highlights the biomarker investigation for cancer diagnosis, prognosis and response to treatment. Finally, some emerging challenges in the computational analysis of cancer methylome data are summarized.
Artificial neural networks applied to FTIR and FT-Raman spectra in biomedical applications (1998)

Biomedical applications of vibrational spectroscopy developed for routine analysis require reliable methods for data evaluation. Artificial neural networks open a new perspective for the spectra differentiation and identification of biologic samples with their small spectral variance. Spectral libraries based on different combined neural networks have been developed using FT-IR and FT-Raman spectra for bacteria and yeast identification.
Multi-device Driver Synthesis Flow for Heterogeneous Hierarchical Systems (2012)

Heterogeneous hierarchical architectures result from the interconnection of several heterogeneous MPSoCs through an efficient communication infrastructure. Each communication between two processing units requires the use of hardware devices managed by a software driver responsible to initialize, handle and complete the communication. This paper describes a multi-device driver synthesis flow based on available communication paths of the architecture. A small set of generic driver templates is available in a driver library. The flow is in charge to select one correct driver template from the library, and then to configure and specialize it in order to produce the source code. The effectiveness of our approach is illustrated by a significant example.
Effect of Ancillary Ligands on the Reactivity and Structure of Zinc Polysulfido Complexes (1998)

The pentacoordinate complex ZnS4(PMDETA) (1) is formed by treatment of ZnS6(TMEDA) (2) with the tridentate ligand pentamethyldiethylenetriamine (PMDETA). 1H NMR studies show that samples of 1 react with elemental sulfur to produce a significant (<30%) amount of a second polysulfido complex, assigned as ZnS5(PMDETA). Crystallographic studies reveal that 1 has a ZnN3S2 coordination sphere with a distorted trigonal bipyramidal structure. The inversion of the stereochemistry at Zn in 1 has been observed by variable-temperature 1H NMR spectroscopy. Neither free PMDETA, elemental sulfur, nor ZnS5(PMDETA) affects the coalescence behavior of 1. The isomerization mechanism proposed for this process involves the dissociation of the central amine, formation of a tetrahedral ZnN2S2 intermediate, and inversion at the central nitrogen, followed by recoordination of the central amine. Other PMDETA complexes studied in this work are subject to similar dynamics. Reactivity studies indicate that complex 1 is significantly more nucleophilic than the corresponding ZnS6(TMEDA), the enhanced nucleophilicity being attributed to the influence of the third amine ligand. Complex 1 reacts rapidly at room with dimethyl acetylenedicarboxylate (DMAD) to give the dithiolene complex ZnS2C2(CO2Me)2(PMDETA) (3). The rate of the DMAD reaction was >100 times faster higher than that for the reaction of ZnS6(TMEDA) with DMAD, indicative of the enhanced nucleophilicity of the sulfur ligands in 1. As further evidence for the enhanced nucleophilicity of its polysulfido ligand, 1 reacts with other unsaturated species such as CS2 and the dithiocarbonate C2(S2CO)2 to give ZnS3CS(PMDETA) and Zn(S2C2S2CO)(PMDETA), respectively. The perthiocarbonate reacts further with PPh3 to give ZnS2CS(PMDETA).
An Approach to the Optimum Design of Sucker-rod Pumping System (2010)

A modern methodology is presented for the optimum design of sucker rod pumping system. The pump setting depth and rod string tapers were determined for any production rate by an iteration algorithm. The optimization criterion was proposed to select the optimum pumping mode from the combinations of pumping parameters. The results show that size of pumping unit, plunger size, stroke length, pumping speed and rod string taper are the basic design variables that characterize the system. Pump setting depth and water production rate are the most important factors for the optimization criterion. Production rate increases monotonically with the design variables and load capacity. The stroke length increases while the load capacity decreases, and the plunger diameter decreases due to increases in stroke length for the identical pump setting depth and production rate. Short stroke length, low pumping speed, small load capacity and plunger diameter characterize the sucker-rod pump of CBM wells in China.
Effects of some terpenes on the in vitro permeation of LHRH through newborn pig skin. (2009)

The objective of this work was to investigate the effect of oxygen containing terpenes (carvacrol, menthol and carvone) at 5%w/v in hydroalcoholic mixtures (40% ethanol) on the permeation of LHRH across newborn pig skin in vitro. In addition, the amount of LHRH retained in the skin after 24 h of diffusion was determined. It was found that the passive permeation of LHRH was very limited. Although percutaneous absorption of LHRH improved in the presence of the enhancers, a significant enhancement was observed only with carvacrol, an aromatic terpene. The rank order of enhancement ratio for skin permeation was found to be carvacrol > carvone > menthol. The enhancers also affected the retention of LHRH in the skin. The rank order of enhancement ratio for skin retention was carvone > carvacrol > menthol. The results of the in vitro skin metabolism study of LHRH using fresh newborn pig skin showed that the degradation products were detected and the amount of the degraded LHRH increased with increasing duration of incubation time.
The role of surface-gate technology for AlGaAs/GaAs nanostructures (1994)

Since its first demonstration in 1986, the technique of employing surface-gate designs to define submicrometre-size geometries in the two-dimensional electron gas of AlGaAs/GaAs heterostructures has yielded a wide range of studies of semiconductor physics and novel modes of device operation. To have a future impact in this role, new gate architectures will be required to further develop the technique's ability to tune device geometries through the applied gate bias. Past and future aspects of this system are reviewed in terms of semiconductor physics, technology and device application, and the implications of recent approaches to gate designs are discussed.
A practical countercurrent fluid catalytic cracking regenerator model for <i>in situ</i> operation optimization (2011)

Abstract A practical countercurrent fluid catalytic cracking (FCC) regenerator model with improved descriptions of gas and solid flow patterns is proposed. A three‐zone and two‐phase gas model was utilized to describe the gas flow through the regenerator, addressing the different phase mass‐transfer properties in the different zones. A new two‐continuously stirred‐tank reactor‐with‐interchange model was used to describe the solid flow and to address the effect of freeboard on catalyst regeneration. Otherwise, this model also considered the usually adopted expanding section for reducing solid carryover. The model was programmed in Matlab language with coupled hydrodynamics and reaction kinetics models and tested and validated by the data from an industrial FCC regenerator operated under both partial and full CO combustion modes. After fitting a single model parameter, the interchange solid flux between the dense bed and freeboard, the model predictions were in reasonable agreement with the commercial data for both modes. © 2011 American Institute of Chemical Engineers AIChE J, 2012
Storing continuous media objects using parallelism with merging (2002)

Many new applications are being developed that capitalize on recent advances in multimedia systems. Such systems provide users with access to images, video clips, and audio samples as well as traditional text. A major challenge is to store the data for continuous media such as video and audio in such a way as to guarantee delay-free user input and output. We propose a hybrid solution to this challenge which combines the use of I/O parallelism with merging techniques for continuous media. These parallelism with merging (PWM) techniques outperformed techniques based solely on parallelism in simulation experiments.
Bi4Ti3O12 Synthesized by High Temperature Solid Phase Method and it's Visible Catalytic Activity (2013)

Oxides containing bismuth with layer structures are well known for their unique properties and high visible catalytic activity. In this paper, Bi2O3 and TiO2 were used as raw materials to synthesize Bi4Ti3O12 by high temperature solid phase method. The shape and crystal structure of Bi4Ti3O12 were characterized via X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM), Transmission electron microscopy (TEM), High resolution TEM (HRTEM), and Selected area electron diffraction (SAED). The photochemical characteristics of products were measured by UV-Vis absorption. We focused on the environmental application of the prepared nanoparticles for the destructions of chlorine phenol (4-CP) and microcystin-RR (MC-RR) under visible light irradiation (> 420 nm). The results demonstrated that nearly all of 4-CP and MC-RR were degraded by Bi4Ti3O12 which showed superior photocatalytic activity. At the same time, transient oxidative species generated during photocatalysis were tracked by Electron spin resonance (EPR), which indicated that the major oxidative species in the system were hydroxyl radical (OH) and superoxide radical (O).
EFFECTS OF GROWTH HORMONE, PROLACTIN AND THYROXINE ON BODY WEIGHT, SOMATOMEDIN-LIKE ACTIVITY AND IN-VIVO SULPHATION OF CARTILAGE IN HYPOPITUITARY DWARF MICE (1980)

Hypopituitary dwarf mice were found to have reduced levels of serum somatomedin-like activity compared with normal mice of the Snell strain. Treatment with bovine growth hormone for 3 and 7 days resulted in growth without significantly increased levels of serum somatomedin-like activity, as detected by in-vitro uptake of 35SO4(2-) into normal rat cartilage; only after treatment for 14 days was somatomedin activity significantly raised. However, treatment for 2 days with bovine growth hormone, bovine prolactin or thyroxine resulted in a dose-dependent increase in in-vivo uptake of 35SO4(2-) into dwarf mouse costal cartilage; growth hormone and thyroxine did not act synergistically. Ten days of treatment with growth hormone promoted a dose-dependent increase in both growth (increased weight gain and tail length) and in-vivo of 35SO4(2-). Increase in tail length was correlated with uptake of 35S04(2-). Thus, in-vivo uptake of 35SO4(2-) into dwarf mouse costal cartilage provides a sensitive method for detecting a dose-related effect of growth hormone.
Requirements of a Quality of Service (QoS) Solution for Mobile IP (2003)

Mobile IP ensures correct routing of packets to a mobile node as the mobile node changes its point of attachment to the Internet. However, it is also required to provide proper Quality of Service (QoS) forwarding treatment to the mobile node's packet stream at the intermediate nodes in the network, so that QoS-sensitive IP services can be supported over Mobile IP. This document describes requirements for an IP QoS mechanism for its satisfactory operation with Mobile IP.

Amphiregulin induces human ovarian cancer cell invasion by down‐regulating E‐cadherin expression (2014)

Aberrant epidermal growth factor receptor (EGFR) activation is associated with ovarian cancer progression. In this study, we report that the EGFR ligand amphiregulin (AREG) stimulates cell invasion and down-regulates E-cadherin expression in two human ovarian cancer cell lines, SKOV3 and OVCAR5. In addition, AREG increases the expression of transcriptional repressors of E-cadherin including SNAIL, SLUG and ZEB1. siRNA targeting SNAIL or SLUG abolishes AREG-induced cell invasion. Moreover, ERK1/2 and AKT pathways are involved in AREG-induced E-cadherin down-regulation and cell invasion. Finally, we show that three EGFR ligands, AREG, epidermal growth factor (EGF) and transforming growth factor-α (TGF-α), exhibit comparable effects in down-regulating E-cadherin and promoting cell invasion. This study demonstrates that AREG induces ovarian cancer cell invasion by down-regulating E-cadherin expression.
