Integrated communication radio navigation and identification system (ICRNI) (2002)

A description is given of the integrated communication, radio navigation, and identification (ICRNI) system which has been developed to resolve operational and logistical problems arising from the large quantities of communication equipment in the modern airborne platform and the heavy workload required to operate them. The ICRNI system was designed to fulfil the following objectives: centralized operation using the avionics display system; operation and control of communication, radio navigation, and identification equipment, and audio devices; equipment/channel selection; synthetic voice and tonal warning function; definition of priorities and parameters for alarms; failure tolerance, enabling communication operation during major failures of the system; and integration with avionics. The system has the following operational advantages: easy, centralized operation and display; flexibility; dynamic equipment (channel) allocation; digital switching which allows complete flexibility in switching and control; synthetic voice and tonal alarms; priorities and parameter controlled alarms; availability and survivability; maintainability; fault tolerance with real-time reallocations and backup capabilities; and reduction of both space and weight in the aircraft.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Study on the Control Methods Based on 3-DOF Helicopter Model (2012)

The 3 degree of freedom (3-DOF) helicopter system is a typical higher-order times, instability, multi-variable, nonlinear and strong coupling control system. This paper presents the analysis of the mathematical model and the basic principle of PID control and fuzzy PID control, which are based on 3-DOF helicopter systems. In allusion to balance control of 3-DOF helicopter system, PID controller and fuzzy PID controller are designed respectively to control the model. The MATLAB simulation results demonstrate the control effects of both controllers achieve the requirements in this system, and fuzzy self-tuning PID shows more advantages.
Some Problems of the Cracking Mechanism of Hydrocarbons (1970)

The model of the cracking mechanism of olefins proposed by Voevodsky should lead to a strong dependence of olefin cracking products on temperature and pressure. This was not observed. The author proposes a chain olefin cracking mechanism when chains are being formed via a series of displacement and addition reactions of the radicals on π-bonds. Some influence of the paraffinic and cycloparaffinic products on the kinetics and mechanism is considered. Decomposition of olefins (primary cracking products) defines the kinetic of summary reaction.
Touching Gold Nanoparticle Chain Based Plasmonic Antenna Arrays and Optical Metamaterials (2014)

The control of light–material interactions at the nanoscale requires optical elements with sizes much smaller than the wavelength of light. Plasmonic nanostructures and optical metamaterials enable drastic control and manipulation of light at such small scales. However it is quite challenging to further reduce the size of resonant elements using conventional plasmonic nanostructures. In this paper, we propose novel optical resonators that rely on the conducting plasmon mode of touching nanoparticle chains that enable significant size reduction when compared with widely used nanostripe antennas and U-shaped split-ring resonators. We employ full-field electromagnetic simulations to study the resonance mechanisms of nanoparticle chain arrays. In comparison with the nanobar plasmonic antennas, a nanoparticle chain based antenna with similar physical sizes operates at larger wavelengths, opening routes for deep subwavelength plasmonic resonators. Moreover, using nanoshell chain arrays, we demonstrate an optical resonator that is 10 times smaller than the resonance wavelength (λ/10). Similarly, nanoparticle-based split-ring resonators provide significant size reduction that could be used for smaller metamaterial and metasurface building blocks. Designing nanoparticle-based resonant elements is a promising route for achieving optical metamaterials with smoother resonance dispersion and lower optical losses.
Towards an Architectural Treatment of Software Security: a Connector-Centric Approach (2005)

Security is a very important concern for software architecture and software components. Previous modeling approaches provide insufficient support for an in-depth treatment of security. This paper argues for a more comprehensive treatment based on software connectors. Connectors provide a suitable vehicle to model, capture, and enforce security. Our approach models security principal, privilege, trust, and context of architectural constituents. Extending our existing architecture description language and support tools, our approach can facilitate describing the security characteristics of an architecture generating enabling infrastructure, and monitoring run-time conformance. Initial results of applying this approach are illustrated through a case study. The contribution of this research is a deeper and more comprehensive treatment of architectural security through software connectors.
Francisella philomiragia subsp. noatunensis subsp. nov., isolated from farmed Atlantic cod (Gadus morhua L.) (2007)

Seven bacterial isolates from farmed Atlantic cod displaying chronic granulomatous disease were characterized by phenotypic and molecular taxonomic methods. The isolates were Gram-negative, facultatively intracellular, non-motile, strictly aerobic coccobacilli which produced H(2)S from cysteine-supplemented media and are therefore phenotypically consistent with members of the genus Francisella. Comparison of 16S rRNA gene sequences and six partial housekeeping gene sequences (groEL, shdA, rpoB, rpoA, pgm and atpA) confirmed the organism as a member of the genus Francisella, with Francisella philomiragia as its closest relative (99.3 % 16S rRNA gene sequence similarity, 92.2-99.0 % housekeeping gene sequence similarity). Despite the close relationship with F. philomiragia, isolates from Atlantic cod could be readily distinguished phenotypically and genetically from F. philomiragia ATCC 25015(T). DNA-DNA hybridization studies revealed a mean reassociation value of 68 %. Thus, on the basis of phenotypic and molecular genetic evidence, we propose that the strains isolated from Atlantic cod should be recognized as Francisella philomiragia subsp. noatunensis subsp. nov. with the type strain 2005/50/F292-6C(T) (=NCIMB 14265(T)=LMG 23800(T)). Francisella philomiragia ATCC 25015(T) (=DSM 735(T)) is reclassified as Francisella philomiragia subsp. philomiragia subsp. nov.
Water-Based Insulating Fluids for Deep-Water Riser Applications (2004)

Abstract Uncontrolled heat transfer from production tubing to outer annuli, especially in deep-water riser sections, can cause the deposition of sludge, paraffin and asphaltene materials and contribute to the formation of gas hydrates. It also can limit the shut-in time if there is a need to shut down the well for remedial operations. Generally, deep-water risers can be insulated externally, or alternatively, insulated by placing nitrogen gas into the riser annulus. In recent years, a new water-based thermal insulating fluid system with superior thermal properties has been developed and used in field applications. This new system provides an ideal rheological profile to significantly reduce fluid convection caused by temperature differential and to facilitate fluid placement into the riser annulus. This system has been successfully used as an alternative to the current insulation method in deep-water risers in the Gulf of Mexico. Laboratory-scale equipment and a full-scale test well were constructed to evaluate the thermal insulation properties of fluids. This paper will detail both testing procedures and methods. Steady-state heat transfer and cool down test results on the new insulation fluid will be reviewed for both set-ups. The results will be discussed along with the results from similar tests on conventional brine based packer fluid, current insulation fluids, as well as nitrogen (air) and argon. The full-scale test data will be discussed in relation to modeling wellbore heat transfer. Field cases in GOM are also summarized to demonstrate the effectiveness of this fluid system.

Early anther ablation triggers parthenocarpic fruit development in tomato (2013)

Fruit set and fruit development in tomato is largely affected by changes in environmental conditions, therefore autonomous fruit set independent of fertilization is a highly desirable trait in tomato. Here, we report the production and characterization of male-sterile transgenic plants that produce parthenocarpic fruits in two tomato cultivars (Micro-Tom and Moneymaker). We generated male-sterility using the cytotoxic gene barnase targeted to the anthers with the PsEND1 anther-specific promoter. The ovaries of these plants grew in the absence of fertilization producing seedless, parthenocarpic fruits. Early anther ablation is essential to trigger the developing of the transgenic ovaries into fruits, in the absence of the signals usually generated during pollination and fertilization. Ovaries are fully functional and can be manually pollinated to obtain seeds. The transgenic plants obtained in the commercial cultivar Moneymaker show that the parthenocarpic development of the fruit does not have negative consequences in fruit quality. Throughout metabolomic analyses of the tomato fruits, we have identified two elite lines which showed increased levels of several health promoting metabolites and volatile compounds. Thus, early anther ablation can be considered a useful tool to promote fruit set and to obtain seedless and good quality fruits in tomato plants. These plants are also useful parental lines to be used in hybrid breeding approaches.
Selective Hippocampal Lesions Differentially Affect the Phenotypic Fate of Transplanted Neuronal Precursor Cells (1996)

RN33B cells, a CNS-derived neuronal precursor cell line, transplanted into normal adult rat hippocampus can survive and morphologically differentiate with their ultimate morphology dependent on the integration site. This study examined the differentiation and structural integration of RN33B cells transplanted into the lesioned adult hippocampus. Pyramidal neurons of the CA1-3 regions or granular neurons in the dentate gyrus were preferentially destroyed by unilateral intraventricular kainic-acid or intradentate colchicine injections, respectively. One week after the lesion, a suspension of undifferentiated beta-galactosidase (beta-gal)-labeled RN33B cells was stereotaxically transplanted into the lesioned or the contralateral hippocampus. After 5-7 weeks, sections of the recipient brains were analyzed by toluidine blue staining and immunohistochemistry for beta-gal, GFAP, and OX-42. A reactive gliosis was observed on the lesioned side which persisted up to 7 weeks postlesion (the latest time point examined). RN33b cells survived in the lesioned hippocampus and assumed variable morphologies depending on the hippocampal layer into which they integrated. Only RN33B cells located in intact or partially damaged cell layers or in the unlesioned contralateral hippocampus differentiated with morphologies similar to those of endogenous neurons characteristic of those layers. Cells located in layers completely depleted of endogenous neurons assumed bipolar morphologies or sent out multiple processes with no structural polarity, unlike the neuronal morphologies characteristically seen in intact hippocampal cell layers. These data suggest that the presence of some endogenous neurons and partially conserved cytoarchitectural organization are essential for immortalized neuroepithelial precursor cells to differentiate into region-specific neuronal cell types.
A simplified method for determining phenotypic traits in patients with obstructive sleep apnea (2013)

We previously published a method for measuring several physiological traits causing obstructive sleep apnea (OSA). The method, however, had a relatively low success rate (76%) and required mathematical modeling, potentially limiting its application. This paper presents a substantial revision of that technique. To make the measurements, continuous positive airway pressure (CPAP) was manipulated during sleep to quantify 1) eupneic ventilatory demand, 2) the level of ventilation at which arousals begin to occur, 3) ventilation off CPAP (nasal pressure = 0 cmH(2)O) when the pharyngeal muscles are activated during sleep, and 4) ventilation off CPAP when the pharyngeal muscles are relatively passive. These traits could be determined in all 13 participants (100% success rate). There was substantial intersubject variability in the reduction in ventilation that individuals could tolerate before having arousals (difference between ventilations #1 and #2 ranged from 0.7 to 2.9 liters/min) and in the amount of ventilatory compensation that individuals could generate (difference between ventilations #3 and #4 ranged from -0.5 to 5.5 liters/min). Importantly, the measurements accurately reflected clinical metrics; the difference between ventilations #2 and #3, a measure of the gap that must be overcome to achieve stable breathing during sleep, correlated with the apnea-hypopnea index (r = 0.9, P < 0.001). An additional procedure was added to the technique to measure loop gain (sensitivity of the ventilatory control system), which allowed arousal threshold and upper airway gain (response of the upper airway to increasing ventilatory drive) to be quantified as well. Of note, the traits were generally repeatable when measured on a second night in 5 individuals. This technique is a relatively simple way of defining mechanisms underlying OSA and could potentially be used in a clinical setting to individualize therapy.
The Wnt Receptor Ryk Plays a Role in Mammalian Planar Cell Polarity Signaling (2012)

Wnts are essential for a wide range of developmental processes, including cell growth, division, and differentiation. Some of these processes signal via the planar cell polarity (PCP) pathway, which is a β-catenin-independent Wnt signaling pathway. Previous studies have shown that Ryk, a member of the receptor tyrosine kinase family, can bind to Wnts. Ryk is required for normal axon guidance and neuronal differentiation during development. Here, we demonstrate that mammalian Ryk interacts with the Wnt/PCP pathway. In vitro analysis showed that the Wnt inhibitory factor domain of Ryk was necessary for Wnt binding. Detailed analysis of two vertebrate model organisms showed Ryk phenotypes consistent with PCP signaling. In zebrafish, gene knockdown using morpholinos revealed a genetic interaction between Ryk and Wnt11 during the PCP pathway-regulated process of embryo convergent extension. Ryk-deficient mouse embryos displayed disrupted polarity of stereociliary hair cells in the cochlea, a characteristic of disturbed PCP signaling. This PCP defect was also observed in mouse embryos that were double heterozygotes for Ryk and Looptail (containing a mutation in the core Wnt/PCP pathway gene Vangl2) but not in either of the single heterozygotes, suggesting a genetic interaction between Ryk and Vangl2. Co-immunoprecipitation studies demonstrated that RYK and VANGL2 proteins form a complex, whereas RYK also activated RhoA, a downstream effector of PCP signaling. Overall, our data suggest an important role for Ryk in Wnt/planar cell polarity signaling during vertebrate development via the Vangl2 signaling pathway, as demonstrated in the mouse cochlea.
Random Networks of Single-Walled Carbon Nanotubes (2004)

The self-assembled two-dimensional random networks composed of isolated SWNTs are obtained by a simple floating catalyst CVD method. A remarkable advantage of this technique is that the random networks can be formed at relatively low temperature with a wide density range, which is distinct from the previous reports. We also find that the deposited SWNTs constituting the networks are isolated rather than in bundles, and this result should be help for improving the preparation technique and exploring the formation mechanism of SWNTs.
The Body Build of Patients With Slipped Capital Femoral Epiphysis (1972)

Analysis of heights and weights of children with slipped capital femoral epiphysis in Connecticut and in the Southwestern United States indicated that about half of the patients in both areas had weights at or above the 95th percentile for their age and about half had weights at or above the 97th percentile for their height. In Connecticut there was an excess of abnormally tall girls and of tall and short boys; in the Southwest there was an excess of short boys. There was no evidence that tall,<i>thin</i>children are at high risk for slipped epiphysis. The suggestion is made that children who combine overweight with slower than average maturation may be at particularly high risk for slipped epiphysis.
Prominent IgM rheumatoid factor production by human cord blood lymphocytes stimulated in vitro with <i>Staphylococcus aureus</i> Cowan I. (1987)

We previously reported that Staphylococcus aureus Cowan I (SAC) is a potent stimulant of IgM rheumatoid factor (RF) production by normal adult peripheral blood mononuclear cells. In the current study, we compared the capacity of normal adult peripheral blood mononuclear cells and cord blood mononuclear cells to produce IgM RF. Although both populations of cells consistently produced IgM RF in response to SAC, the quantity of RF produced by cord blood cells (128 +/- 18 ng/ml, mean +/- SEM) greatly exceeded that of adult cells (37 +/- 5 ng/ml, p less than 0.0005) even though both populations of cells demonstrated comparable total IgM responses. Remarkably, 16.7% of total IgM produced by cord blood cells in response to SAC showed RF activity compared to only 3.4% (p less than 0.0001) of the total IgM produced by SAC-stimulated adult cells. Thus, precursors of IgM RF-secreting cells are not only a consistent feature of the normal adult human B cell repertoire, but they are especially represented at the time of birth. These findings are consistent with the hypothesis that IgM RF originates from germ line genes and underscore the utility of SAC as a probe for analyzing the production of this autoantibody.

Dynamic model of battery charging (2015)

In smart grid environment, batteries charged from grids during off peak hours (specially late night) for use either in electric vehicles or as emergency power source play an important role as Distributed Energy Resources (DERs) at the demand side. It is important to estimate the support available from such a resource for energy management during a contingency. In this paper, a dynamic (time varying) model of charging with constant current has been developed for lead acid batteries. This model provides a means to compute analytically the open circuit voltage (OCV) at a given time and the corresponding state of charge (SOC). A few sets of data obtained from practical tests of different sizes of batteries have been used to determine model parameters. The model is then applied to another battery and the output compared with its available test data for validation. As lead acid batteries are very common and affordable these have been used in this work. However, the methodology reported in this paper can always be extended to develop similar models for Nickel Metal Hydride (NiMH) or Lithium ion (Li-ion) batteries. Therefore, this paper presents a generic model that can be used for other, newer battery types.
