Aging Enhances Autonomic Support of Blood Pressure in Women (2013)

The autonomic nervous system plays a central role in both acute and chronic blood pressure regulation in humans. The activity of the sympathetic branch of the autonomic nervous system is positively associated with peripheral resistance, an important determinant of mean arterial pressure in men. In contrast, there is no association between sympathetic nerve activity and peripheral resistance in women before menopause, yet a positive association after menopause. We hypothesized that autonomic support of blood pressure is higher after menopause in women. We examined the effect of ganglionic blockade on arterial blood pressure and how this relates to baseline muscle sympathetic nerve activity in 12 young (25±1 years) and 12 older postmenopausal (61±2 years) women. The women were studied before and during autonomic blockade using trimethaphan camsylate. At baseline, muscle sympathetic nerve activity burst frequency and burst incidence were higher in the older women (33±3 versus 15±1 bursts/min; 57±5 versus 25±2 bursts/100 heartbeats, respectively; P<0.05). Muscle sympathetic nerve activity bursts were abolished by trimethaphan within minutes. Older women had a greater decrease in mean arterial pressure (-29±2 versus -9±2 mm Hg; P<0.01) and total peripheral resistance (-10±1 versus -5±1 mm Hg/L per minute; P<0.01) during trimethaphan. Baseline muscle sympathetic nerve activity was associated with the decrease in mean arterial pressure during trimethaphan (r=-0.74; P<0.05). In summary, our results suggest that autonomic support of blood pressure is greater in older women compared with young women and that elevated sympathetic nerve activity in older women contributes importantly to the increased incidence of hypertension after menopause.
A Survey of Augmentative and Alternative Communication Service Provision in Hong Kong (2010)

A survey was conducted to understand the service provisions for augmentative and alternative communication (AAC) in Hong Kong. The response rates of special pre-school training centers and special schools were 59% and 71%, respectively. The response rate of adult settings was 18%. Results indicated that a higher proportion of students identified as having complex communication needs had access to AAC service provision in schools for children with intellectual and physical disabilities than those in special pre-school training centres and other types of special schools. Generalization of AAC service beyond the classroom setting remains problematic. Seventy-two percent of the respondents were dissatisfied with the training in AAC that they received during their basic professional preparation. More advocacy work is needed to increase awareness and knowledge of AAC use in Hong Kong.
Alpha2-and beta2-adrenoceptor downregulation in marathon runners (1989)

The regulation of platelet alpha 2- and lymphocyte beta 2-adrenoceptor densities by alterations in endogenous catecholamines was examined. In order to activate the sympathetic nervous system eight trained male normotensive subjects carried out a marathon run. Adrenoceptor densities and plasma catecholamine concentrations were measured before and immediately after the run. Platelet alpha 2-adrenoceptor density and lymphocyte beta-adrenoceptor density decreased after the run (P less than 0.05), whereas both plasma noradrenaline and adrenaline concentrations increased (P less than 0.01). Mean arterial pressure decreased (P less than 0.05), and the heart rate increased (P less than 0.001). The data suggest that increases in endogenous catecholamine concentrations cause downregulation of both alpha- and beta-adrenoceptor densities on human blood cells.

FAILURE-SENSITIVE ANALYSIS OF PARALLEL ALGORITHMS WITH CONTROLLED MEMORY ACCESS CONCURRENCY (2007)

The abstract problem of using P failure-prone processors to cooperatively update all locations of an N-element shared array is called Write-All. Solutions to Write-All can be used iteratively to construct efficient simulations of PRAM algorithms on failure-prone PRAMS. Such use of Write-All in simulations is abstracted in terms of the iterative Write-All problem. The efficiency of the algorithmic solutions for Write-All and iterative Write-All is measured in terms of work complexity where all processing steps taken by the processors are counted. This paper considers determinitic solutions for the Write-All and iterative Write-All problems in the fail-stop synchronous CRCW PRAM model where memory access concurrency needs to be controlled. A deterministic algorithm of Kanellakis, Michailidis, and Shvartsman [16] efficiently solves the Write-All problem in this model, while controlling read and write memory access concurrency. However it was not shown how the number of processor failures f affects the work efficiency of the algorithm. The results herein give a new analysis of the algorithm [16] that obtain failure-sensitive work bounds, while retaining the known memory access concurrency bounds. Specifically, the new result expresses the work bound as a function of N, Pandf. Another contribution in this paper is the new failure-sensitive analysis for iterative Write-All with controlled memory access concurrency. This result yields tighter bounds on work (vs. [16]) for simulations of PRAM algorithms on fail-stop PRAMS.
Synthesis of phosphatidylinositol 3,4,5-trisphosphate in permeabilized neutrophils regulated by receptors and G-proteins (1993)

Formylated Met-Leu-Phe (fMLP), platelet-activating factor (PAF), ATP, and various nonhydrolyzable guanine nucleotides stimulated accumulation of phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) in intact human neutrophils. A protocol was devised to selectively inhibit the capacity of the nucleotide-sensitive receptors to elicit accumulation of PtdIns (3,4,5)P3. This enabled study of the regulation of phosphoinositide 3OH-kinase (PI3K) activities in permeabilized neutrophils free from interference due to activation of cell-surface nucleotide receptors. FMLP, PAF, and nonhydrolyzable GTP analogues stimulated an increase in the concentration, and rate of synthesis, of PtdIns(3,4,5)P3 in permeabilized neutrophils by increasing the rate of a PtdIns(4,5)P2-directed PI3K-catalyzed reaction. A number of characteristics of these responses, including their relative sensitivities to inhibition by pertussis toxin and guanosine 5'-beta-(thio)diphosphate, suggested that fMLP and PAF increased this PI3K activity via the actions of heterotrimeric G-proteins. Basal and guanosine 5'-gamma-(thio)triphosphate/fMLP-stimulated increases in PI3K activity were resistant to changes in free calcium concentrations, staurosporine, acute treatment with phorbol esters, and evidently to permeabilization. This, in conjunction with other work, indicates that the PAF and fMLP-induced increase in PtdIns(4,5)P2-directed PI3K activity is not being produced via activation of a currently defined G-protein regulated effector enzyme, or a protein tyrosine kinase coordinated mechanism of a type already known to regulate PI3K activities.
Monocyte enrichment of mononuclear apheresis preparations with a multistep back‐flush procedure on a cord blood filter (2005)

The use of a multi-step back flush procedure with a cord blood filter resulted in rapid enrichment of viable and functional monocytes from mononuclear apheresis units with significant reduction of contaminating platelets and red cells.
Polychrome Stains for High Resolution Light Microscopy (1983)

Plastic embedding of tissue is a procedure that has been recently introduced in routine histopathology. Epoxy embedding produces the optimal preservation of tissues for light microscopy, but routine acid stains on epoxy sections are difficult to perform. Basic polychromatic stains are used instead. In this article a single polychrome stain (toluidine blue) is compared with a multiple polychrome stain (toluidine blue and basic fuchsin) in nondeplasticized, osmicated epoxy sections. Since the multiple polychrome stains obviate the need for most routine special stains, these polychrome stains appear to be more practical for routine high resolution light microscopy.
1.3 mu m multiquantum well decoupled confinement heterostructure (MQW-DCH) laser diodes (1993)

A 1.3- mu m multi-quantum-well decoupled confinement heterostructure (MQW-DCH) laser diode has been developed. This structure introduces internal barriers between the active quantum wells and the optical waveguide. It is thus possible to have, at the same time, deep quantum wells to prevent carrier leakage and a strong optical waveguide with a high confinement factor. The barrier parameters have been optimized using numerical modeling tools, and the DCH laser diode has been built using chemical beam epitaxy. The broad-area transparency current density is 140 A-cm/sup -2/, the internal efficiency is 0.83, the waveguide loss is 5 cm/sup -1/. and T/sub 0/ = 62 K. Ridge waveguide laser diodes have a room temperature threshold of 8 mA and an efficiency of 0.32 mW/mA.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

"Their ideas of beauty are, on the whole, the same as ours": Consistency and variability in the cross-cultural perception of female physical attractiveness. (1995)

The consistency of physical attractiveness ratings across cultural groups was examined. In Study 1, recently arrived native Asian and Hispanic students and White Americans rated the attractiveness of Asian, Hispanic, Black, and White photographed women. The mean correlation between groups in attractiveness ratings was r =.93. Asians, Hispanics, and Whites were equally influenced by many facial features, but Asians were less influenced by some sexual maturity and expressive features. In Study 2, Taiwanese attractiveness ratings correlated with prior Asian, Hispanic, and American ratings, mean r =.91. Supporting Study 1, the Taiwanese also were less positively influenced by certain sexual maturity and expressive features. Exposure to Western media did not influence attractiveness ratings in either study. In Study 3, Black and White American men rated the attractiveness of Black female facial photos and body types. Mean facial attractiveness ratings were highly correlated (r = .94), but as predicted Blacks and Whites varied in judging bodies
Advanced steel reheat furnaces: Research and development. Final report (1999)

The purpose of this report is to present the results of two phases of a three-phase project to develop and evaluate an Advanced Steel Reheat Furnace (SSRF) concept which incorporates two proven and commercialized technologies, oxy-fuel enriched air (OEA) combustion and gas reburning (GR). The combined technologies aim to improve furnace productivity with higher flame radiant heat transfer in the heating zones of a steel reheat furnace while controlling potentially higher NOx emissions from these zones. The project was conducted under a contract sponsored by the Department of Energy (DOE). Specifically, this report summarizes the results of a modeling study and an experimental study to define and evaluate the issues which affect the integration and performance of the combined technologies. Section 2.0 of the report describes the technical approach uses in the development and evaluation of the advanced steel reheat furnace. Section 3.0 presents results of the modeling study applied to a model steel furnace. Experimental validation of the modeling results obtained from EER`s Fuel Evaluation Facility (FEF) pilot-scale furnace discussed in Section 4.0. Section 5.0 provides an economic evaluation on the cost effectiveness of the advanced reheat furnace concept. Section 6.0 concludes the report with recommendations on the applicability of the combined technologies of steel reheat furnaces.
Structural Dynamic System Reconstruction Method for Vibrating Structures (2003)

To determine the natural frequencies and damping ratios of composite laminated plates, we present an efficient modal parameter estimation technique by developing a residual spectrum based structural dynamic system reconstruction. The modal parameters can be estimated from poles and residues of the system transfer functions derived from the state space system matrices. However, for modal parameter estimation of multivariable and higher order structural systems over broad frequency bands, this noniterative algorithm gives high accuracy in determining the natural frequencies and damping ratios. It is numerically well-behaved unlike iterative frequency-response-function (FRF) curve-fitting methods. We also discuss necessary conditions for convergence in Hankel norm and the error bounds of the approximated transfer function for the IDFT-based reconstruction system. From vibration tests on cross-ply and angle-ply composite laminates, the natural frequencies and damping ratios can be identified from the eigenvalues of the structural dynamic system matrix derived by the reconstruction method from the experimental frequency response functions. These results are compared with those of finite-element analysis and single-degree-of-freedom curve-fitting.

Calculating Time Delays of Multiple Active Sources in Live Sound (2010)

Delays caused by differences in distance between sources and microphones cause many problems in live audio, most notably comb filtering. This paper presents a new method that is able to calculate the relative time delays of multiple active sources to multiple microphones where previous methods are unable to. The calculated time delays can be used to compensate for delays that cause comb filtering and can also be used in source separation methods which utilise delays. The proposed method is shown to be able to calculate delays in configurations where other methods fail and is also able to give an estimate of sources physical positions. The results show that multiple delays can be accurately calculated when multiple sources are active and that noise can effect the accuracy of the method.

Barrier Properties for Oxygen Diffusion in a TaSiN Layer (1997)

Annealing in O 2 at temperatures above 650° C is required for a thin ferroelectric capacitor. Reduction of the leakage current and an increase of capacitance can be attained in the charge storage capacitor through this annealing. A stacked structure capacitor cell must be practically employed in metal oxide semiconductor large scale integrated circuits (MOSLSI). In this capacitor cell with a conventional Pt/TiN/poly-Si lower electrode, however, O 2 annealing can not be attained at high temperature because peeling of the TiN barrier layer and the formation of a thin oxide layer at the surface of poly-Si occur. An noncrystalline TaSiN layer has been studied with respect to the barrier effect for oxygen diffusion used in the barrier layer of the lower electrode. The penetration depth of oxygen diffusion decreases markedly with increasing Si composition in a TaSiN layer and reaches 20 nm deep in a Ta .22 Si .35 N .43 layer. However, the resistivity increases with this increase. A good diffusion barrier layer with low sheet resistance is attained in a Ta .50 Si .16 N .34 layer. Penetration depth below 40 nm is obtained in a slightly Si-rich Ta .36 Si .27 N .37 layer for O 2 annealing at 850° C.
Compressed bitmap indices for efficient query processing (2001)

Bitmap indices are useful techniques for improving access speed of high-dimensional data in data warehouses and in large scientific databases. Even though the bitmaps are easy to compress, compressing them can significantly reduce the query processing e#ciency. This is because the operations on the compressed bitmaps are much slower than the same operations on the uncompressed ones. To address this problem, we developed a new word-aligned compression scheme that uses a little more space, but is much faster than earlier methods. Using this compression technique, we evaluate several bitmap encoding schemes, including the equality encoding, the range encoding and the interval encoding. In our tests, the compressed bitmap indices are not only much smaller in size than their uncompressed versions, but are also just as fast in query processing as their uncompressed counterparts. In these tests, the compressed bitmap indices using di#erent encoding schemes show di#erent space and time trade-o#s. To search for more useful choices, we also present several two-level schemes.
On the error probability for a class of binary recursive feedback strategies (1973)

The error probability for a class of binary recursive feedback strategies is evaluated. An exact analysis is given for both a nonsequential and a sequential decision strategy. We obtain the interesting result that even for the nonsequential receiver the error probability vanishes exponentially fast at channel capacity. A similar result had been previously obtained by Horstein for the sequential receiver, but was believed to be a consequence of the sequential nature of his decision strategy. For rates below capacity our feedback strategies have two error exponents, i.e., a lower error exponent <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^- (R)</tex> and an upper error exponent <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^+ (R)</tex> . The lower error exponent <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^- (R)</tex> exhibits an anomalous behavior in that <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^- (R)</tex> increases monotonically from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^- (0) = 0</tex> to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E^- (C) = E(C)</tex> as the rate <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</tex> increases from 0 to capacity.
Calcium channel blocker and calmodulin antagonists affect the gradient of free calcium ions in lily pollen tubes. (1991)

The distribution of intracellular free calcium ions ([Ca2+]i) was measured in pollen tubes of Lilium longiflorum using video imaging microscopy and the calcium sensitive indicators fura-2 and quin-2. The mean [Ca2+]i in growing pollen tubes measured with fura-2 shows a maximum of 1.7 to 2.6 microM in the tube tip and decreases almost exponentially to 60 to 100 nM at 100 microns behind the tip. Using quin-2, the maximum [Ca2+]i was also found in the tube tip but with a lower Ca2+ concentration, namely 1 microM. Addition of the calcium channel blocker La3+ caused a decrease of the [Ca2+]i maximum in the tube tip, indicating a heterogeneous distribution of Ca2+ channels along the plasma membrane of pollen tubes. The [Ca2+]i increased after addition of vanadate or compound 48/80. This suggests an involvement of a calmodulin-dependent Ca2+ pump in generation of the Ca2+ gradient in lily pollen tubes. The high [Ca2+]i found in the tube tip with fura-2 seems to indicate the real Ca2+ concentration and is probably responsible for vesicle fusion, fragmentation of actin filaments, and inhibition of cytoplasmic streaming.
A Chambered Porous Damper for Rotor Vibration Control: Part I — Concept Development (1991)

In this paper a novel, high load chambered porous damper design, supporting analysis, and experimental results are presented. It was demonstrated that significant damping can be generated from the viscous discharge losses of capillary tubes arranged in chambered segments with large radial clearances and that the resulting damping is predictable and fairly constant with speed and eccentricity ratio. This design avoids the non-linearities associated with high eccentricity operation of conventional squeeze film dampers. Controlled orbit tests with a porous chambered configuration were completed and favorably compared with theoretical predictions. The ability to accommodate high steady state and transient imbalance conditions make this damper well suited to a wide range of rotating machinery, including aircraft gas turbine engines.
Friction Powder Metallurgy Materials (2015)

Abstract Friction materials are the components of a mechanism that converts mechanical energy into heat upon sliding contact. This article discusses the selection criteria, manufacturing process, and applications of friction powder metallurgy materials. It provides information on the manufacturing process of powder metallurgy friction materials through a process of mixing/blending, compacting, and sintering. The final machining that they undergo, to ensure that they meet dimensional specifications, is also discussed.
Feature extraction from the electroencephalogram by adaptive segmentation (1977)

This paper describes the feature extraction stage of a proposed pattern recognition system aimed at automatic EEG analysis. The basic pattern-the EEG record-is split into "elementary patterns" called segments and transients, by means of a method relying on linear predictive filtering. Appropriate features, representing power spectra and the time structure of the signal, are then extracted and finally combined into a feature set representing the EEG as a whole. The quality of this representation may be assessed by comparing the original signal with its simulation from the stored features.
Polymeric waveguide Bragg grating filter using soft lithography (2006)

We use the soft lithography technique to fabricate a polymeric waveguide Bragg grating filter. Master grating structure is patterned by e-beam lithography. Using an elastomeric stamp and capillary action, uniform grating structures with very thin residual layers are transferred to the UV curable polymer without the use of an imprint machine. The waveguide layer based on BCB optical polymer is fabricated by conventional optical lithography. This approach provides processing simplicity to fabricate Bragg grating filters.
In vitro deletion mapping of the viral strand replication origin of Pseudomonas bacteriophage Pf3 (1991)

The origin of viral strand replication of the filamentous bacteriophage Pf3 has been characterized in Escherichia coli by in vitro deletion mapping techniques. The origin region was functionally identified by its ability to convey replicative properties to a recombinant plasmid in a polA host in which the replication origin of the vector plasmid is not functional. The origin of Pf3 viral strand replication is contained within a DNA sequence of 139 bp. This sequence covers almost completely one of the intergenic regions of the Pf3 genome, and it specifies both replication initiation and termination functions. Although no nucleotide sequence homology is present between the Pf3 origin of viral strand replication and that of the E. coli filamentous phages Ff (M13, f1, and fd) and IKe, their map positions and functional properties are very similar.
