Assessment of Peripheral Blood Flow in Man by Video Dilution Technique (1981)

Video dilution technique is now available for clinical use in evaluating patients with peripheral vascular disease. The measurements can easily be performed in any modern angiographic suite. The only additional equipment required is a videodensitometer, video tape recorder, and a strip chart recorder. The new technique has been developed and tested in a hydrodynamic model and compared to volumetric flows. Further, the video dilution technique has been compared to electromagnetic flow readings using a canine model to measure the cerebral, renal, splanchnic, and extremity circulation and has proven to be extremely accurate (n = 389; r = 0.99). By applying the technique to patients with peripheral vascular disease, it is possible to evaluate the hemodynamic significance of stenotic lesions and arteriovenous shunts. Other uses of video dilution technique include evaluating the effects of vasoactive drugs and the adequacy of transluminal angioplasty.
Influence of feeding restriction and dietary phosphorus levels on body tissue composition evaluated in vivo by computed tomography, bone mineralisation and sensory properties of the meat from gilts (2019)

Feeding strategy is very important for farmers to improve pig productive parameters and keep its competitive advantage in the market. The computed tomography (CT) technology can evaluate the effect of feeding strategy on the body/carcass tissue and bone composition of living pigs, since it allows the evaluation of the same animal at various moments of growth to avoid serial slaughtering of animals. This thesis at hand investigates the effect of different feeding restriction treatments on productive and carcass quality parameters of gilts using CT during growth and the effect of such treatments on meat quality, sensory properties and consumer preference (experiment 1) and the effect of different feeding strategies with different dietary P and phytases levels on density and the morphological characteristics of the bones of live gilts during growth and in their carcasses via CT images and the effect of these strategies on the chemical and physical characteristics of the bones, carcass and meat quality characteristics (experiment 2)
Chemical Bubble Dynamics and Quantitative Sonochemistry (1998)

We model the collapse of a bubble by taking into account all the energy forms involved (i.e., mechanical, thermal, chemical, and radiative) and compare the calculated radical yields with sonochemical data in H2O. Water decomposition plays a critical role in the energy balance, but trails equilibrium even in bubbles collapsing at subsonic speeds. Integration of the equation of bubble motion coupled with a full chemical mechanism reveals that (1) terminal gas temperatures and Mach numbers ML increase in cooler water, (2) ΓOH, the number of OH-radicals produced per unit applied work at maximum MLwhen bubbles become unstable and disperse into the liquiddecreases at small and very large sound intensities. We show that available data on the sonochemical decomposition of volatile solutessuch as CCl4, which is pyrolyzed within collapsing bubblesare compatible with the efficient conversion of ultrasonic energy into transient cavitation. On this basis we calculate ΓOH = (1 ± 0.5) × 1017 molecules/J for R0 = 2 μm bubbles optimally sonicated at 300 kHz and 2.3 W/cm2 by assuming mass and energy accommodation coefficients of α ≤ 7 × 10-3 and ε ≤ 0.04, respectively, in gas−liquid collisions, and values about 3-fold smaller after averaging over the nuclei size distribution. Since there is negligible radical recombination during dispersal, these ΓOH values represent available oxidant yields, that agree with experimental data on iodide sonochemical oxidation. Bubbles emit little radiation, suggesting that only radial shock waves may heat small regions to the 104−105 K range required by some sonoluminescence experiments. The contribution of this sonoluminescent core to sonochemical action is, however, insignificant. We show that much larger accommodation coefficients would lead to higher temperatures, but also to O atoms rather than OH radicals and ultimately to excess O2, at variance with experimental evidence.

DT controls (2005)

In this paper, we show how traditional physical interface components such as switches, levers, knobs and touch screens can be easily modified to identify who is activating each control. This allows us to change the function per-formed by the control, and the sensory feedback provided by the control itself, dependent upon the user. An auditing function is also available that logs each user's actions. We describe a number of example usage scenarios for our tech-nique, and present two sample implementations.
The role of separation science in proteomics research (2001)

In the last few years there has been an increased effort into the separation, quantification and identification of all proteins in a cell or tissue. This is a review of the role gel electrophoresis, high performance liquid chromatography (HPLC), and capillary electrophoresis (CE) play in proteomics research. The capabilities and limitations of each separation technique have been pointed out. Instrumental strategies for the resolution of cell proteins which are based on efficient separation employing either a single high-resolution procedure or a multidimensional approach on-line or off-line, and a mass spectrometer for protein identification have been reviewed. A comparison of the advantages of multi-dimensional separations such as two-dimensional polyacrylamide gel electrophoresis, HPLC-HPLC, and HPLC-CE to the separation of cell and tissue proteins are discussed. Also, a discussion of novel approaches to protein concentration, separation, detection, and quantification is given.
The Rutgers Arm, a Rehabilitation System in Virtual Reality: A Pilot Study (2006)

Stroke is one of the leading causes of death and disability worldwide. Its prevalence calls for innovative rehabilitation methods. The Rutgers Arm is a novel upper extremity rehabilitation system consisting of a low-friction table, three-dimensional (3D) tracker, custom forearm support, PC workstation, library of Java 3D virtual reality (VR) exercises, clinical database module, and a tele-rehabilitation extension. The system was tested on a chronic stroke subject, under local and tele-rehabilitation conditions, over 5 weeks of training. Results show improvements in arm motor control and shoulder range of motion, corresponding to improved Fugl-Meyer test scores. Exercise duration, level of difficulty, and patient motivation were maintained under tele-rehabilitaion. A 1-week retention trial showed that gains were maintained.
Archeology and Creation Science (1994)

In order to integrate Biblical creation science with the modem discipline of archaeology, creation science itself must become unified, specific, sequential, and definitive. Only then can it provide a basic geochronological framework for Interpreting archaeology. This paper will explore three Biblical creationist models: a development of the post-Flood Ice Age, a treatment of continental separation, and a mathematical equation which translates carbon-14 age data Into real-time equivalents. It will apply these models to uniformitarian ages of ancient cultures, using a Biblical chronology, to begin the process of re-evaluatlng prehistoric archaeology from the perspective of Biblical creation science.

Speech reinforcement based on partial masking effect (2009)

Perceived quality of the speech signal deteriorates significantly in the presence of ambient noise. In this paper, based on the analysis that the partial masking effect is a main source of the quality degradation when interfering signals are present, we propose a novel approach to enhance the perceived quality of speech signal when the ambient noise cannot be directly controlled by reinforcing it so that it can be heard more clearly. To find a suitable reinforcement rule, the loudness perception model proposed by Moore et al. [1] is adopted with the consideration on the prevention of the hearing damage. Experimental results show that the perceived quality and intelligibility can be enhanced under various noise environments.
Distinct <i>cis</i> -Regulatory Elements from the <i>Dlx1/Dlx2</i> Locus Mark Different Progenitor Cell Populations in the Ganglionic Eminences and Different Subtypes of Adult Cortical Interneurons (2007)

Distinct subtypes of cortical GABAergic interneurons provide inhibitory signals that are indispensable for neural network function. The Dlx homeobox genes have a central role in regulating their development and function. We have characterized the activity of three cis-regulatory sequences involved in forebrain expression of vertebrate Dlx genes: upstream regulatory element 2 (URE2), I12b, and I56i. The three regulatory elements display regional and temporal differences in their activities within the lateral ganglionic eminence (LGE), medial ganglionic eminence (MGE), and caudal ganglionic eminence (CGE) and label distinct populations of tangentially migrating neurons at embryonic day 12.5 (E12.5) and E13.5. We provide evidence that the dorsomedial and ventral MGE are distinct sources of tangentially migrating neurons during midgestation. In the adult cortex, URE2 and I12b/I56i are differentially expressed in parvalbumin-, calretinin-, neuropeptide Y-, and neuronal nitric oxide synthase-positive interneurons; I12b and I56i were specifically active in somatostatin-, vasoactive intestinal peptide-, and calbindin-positive interneurons. These data suggest that interneuron subtypes use distinct combinations of Dlx1/Dlx2 enhancers from the time they are specified through adulthood.
Plasma glutathione S-transferase as an early marker of posttraumatic hepatic injury in non-human primates. (1995)

We have hypothesized that the measurement of alpha-glutathione S-transferase (alpha-GST) in serum may provide a suitable sensitive marker of shock-induced liver damage. Six male adult baboons were studied. Hemorrhage was induced by blood withdrawal of 60-70% of the total blood volume down to an arterial pressure of 35-40 mmHg. Then the reinfusion was performed with the heparinized shed blood plus the same amount of Ringer's solution over the next 4 h. Before the start of hemorrhage, 2 mL/kg zymosan-activated plasma was infused to simulate trauma-related complement activation. alpha-GST antigen levels were determined using an anti-human alpha-GST immunoassay (Hepkit). Concentrations of alpha-GST at baseline in baboon were found to be 3.1 +/- 1.8 ng/mL; at the end of the shock period a significant increase in alpha-GST serum levels (74.8 +/- 13.8 ng/mL) was found. In contrast, transaminase levels did not significantly change. From the current evidence in posttraumatic non-human primates, which resemble the clinical situation in several aspects, alpha-GST measurements are a suitable marker of early hepatocellular injury.
Advances in superconducting wire and cable for the superconducting supercollider (1988)

Researchers in government and industry, working together to design the SSC, have advanced the state of the art of superconducting wire. Improved performance (1600 amps/mm/sup 2/ at 7 tesla) has allowed the SSC Central Design Group to design the accelerator to operate at higher magnetic fields. This makes it possible to shrink the circumference of the SSC from 63 miles to 53 miles, thereby achieving an enormous cost reduction. The author describes the process for fabricating the new wire and cable. His purpose is to convey an appreciation for this advanced materials technology, to explain the recent improvements, and to stimulate thought regarding developments one might need to create magnets from the new high-temperature ceramic superconductors. He explains how one fabricates a cable containing 23 strands of superconducting wire, each 0.0318'' in diameter. Each strand contains 7250 filaments of niobium-titanium (NbTi) embedded in a copper matrix. The diameter of each filament is 6 microns.
Regulation of cell wall invertase by a proteinaceous inhibitor (1996)

Suspension-cultured tobacco cells express a cell wall invertase (CWI) and a proteinaceous invertase inhibitor. Both proteins have been purified and characterized. A CWI cDNA clone has been isolated. The N-terminal protein sequence of the inhibitor has been determined showing high similarity with the N-terminal sequence of a tomato invertase inhibitor. A polyclonal antiserum has been raised against the denatured inhibitor protein. The observed changes of CWI activity during cell culture are partially the result of changes in gene expression, however, evidence has accumulated for further regulation by the inhibitor protein. In vivo regulation of CWI by the inhibitor is likely for the following reasons: (1) CWI inhibition is dependent on pH within the range relevant for the apoplasmic space, (2) divalent cations in the millimolar range affect CWI inhibition, (3) substrate protects CWI (but not vacuolar invertase) against inhibition, (4) CWI and inhibitor are co-expressed and co-localized in the apoplasmic space, (5) addition of inhibitor to intact cells causes substrate-protectable inhibition of CWI, (6) an in situ formation of tight complexes between CWI and inhibitor upon starvation of cells could be demonstrated. The results indicate that suspension-cultured tobacco cells are a suitable system to study the effects of an invertase inhibitor on CWI.
ZnO and Zn1-xMnxO Minicrystal by CVT and Temporal Process of Photoelectrons (2006)

The ZnO and Zn1-xMnxO minicrystal were synthesized by chemical vapor transport (CVT). The electron trap structure (donor level) and process on the temporal behavior of photoelectrons of materials were respectively studied by thermo-luminescence and microwave absorption dielectric spectrometry. There are two peaks in the thermo-luminescence spectra in pure ZnO, one is -183 ℃ and the other is -127 ℃, which shows two kinds of electron trap energy level produced by the intrinsic defects in ZnO;but obtain very low thermo-luminescence that only equals to ten percent of pure ZnO in Zn1-xMnxO, which shows that its intensity of electron trap is less. The studies of microwave absorption dielectric spectrometry show that conduction band photoelectrons are two-step exponential decay process in ZnO, the lifetime of rapid process is 83 ns, while slow process is 828 ns, the reason of delay is relaxation effects of electron trap to conduction band photoelectrons. The intensity of electron trap is less in Zn1-xMnxO minicrystal, the relaxation effects of conduction band photoelectrons from electron trap is little, so electrons disappeared quickly at conduction band, and the decay process of photoelectrons is only 10～20 ns.
Surface Enhanced Raman Scattering Sensing with Nanostructures Fabricated by Soft Nanolithography (2009)

The nanospike structures formed with femtosecond laser irradiations have been successfully replicated on the surface of a polyurethane (PU) polymer using a low cost soft nanolithography method. The surface enhanced Raman scattering (SERS) of rhodamine 6G (Rh6G) and dinitrotoluene (DNT) molecules have been measured with silver coated PU nanospike surfaces by a simple portable Raman spectrometer. Compared to a flat silver coated surface, where no Raman Scattering of the molecules can be detected by the simple portable Raman spectrometer, the Raman spectra are enhanced by more than 4 orders of magnitudes. This indicates that the high area/volume ratio and small size of the PU nanospikes can be used for SERS sensing.
Experimental test of Landauer’s principle in single-bit operations on nanomagnetic memory bits (2016)

Minimizing energy dissipation has emerged as the key challenge in continuing to scale the performance of digital computers. The question of whether there exists a fundamental lower limit to the energy required for digital operations is therefore of great interest. A well-known theoretical result put forward by Landauer states that any irreversible single-bit operation on a physical memory element in contact with a heat bath at a temperature T requires at least k B T ln(2) of heat be dissipated from the memory into the environment, where k B is the Boltzmann constant. We report an experimental investigation of the intrinsic energy loss of an adiabatic single-bit reset operation using nanoscale magnetic memory bits, by far the most ubiquitous digital storage technology in use today. Through sensitive, high-precision magnetometry measurements, we observed that the amount of dissipated energy in this process is consistent (within 2 SDs of experimental uncertainty) with the Landauer limit. This result reinforces the connection between "information thermodynamics" and physical systems and also provides a foundation for the development of practical information processing technologies that approach the fundamental limit of energy dissipation. The significance of the result includes insightful direction for future development of information technology.
[Components of membranous labyrinth proteins of guinea pig and the detection of anti-68kD antibody in sensorineural hearing loss]. (1994)

The membranous labyrinth proteins (MLP) of guinea pig were isolated with various methods. The isolations with SDS or Triton X-100 were efficient. Western blot was successfully established and used to detect the anti-MLP antibody. Among 42 cases of idiopathic sensorineural hearing loss, 16 are positive of anti-68kD antibody in their sera with increased IgG, IgM and IgA. Anti-68kD antibody was also found in some normal controls, though it had weaker reaction and less repetition.

Microstructure of Alumina Brazed with a Silver‐Copper‐Titanium Alloy (1990)

Joints of high‐purity Al 2 O 3 were made with a 56Ag‐36Cu‐6Sn‐2Ti (wt%) experimental alloy by vacuum brazing at 900°C for 20 min. The microstructure at the ceramic‐metal interfaces was examined in cross‐sectional specimens of the joints, and phases formed by reaction between the braze filler metal and the Al 2 O 3 were analyzed for composition and crystal structure in a transmission electron microscope. A 0.1‐ to 0.2‐μm‐thick layer formed directly on the Al 2 O 3 surface. This layer was Ti‐rich, had the face‐centered‐cubic crystal structure with a lattice parameter of 0.423 nm, and was identified as oxygen‐deficient γ‐TiO. The second reaction layer was ∼3 μm thick, and it separated the TiO layer from the metallic phases of the braze filler metal. The structure of this layer, as determined by electron diffraction, was diamond cubic of the space group Fd3m , with a lattice parameter of 1.137 nm. The combination of microanalysis and diffraction data confirmed that this phase was Ti 3 (Cu 0.76 Al 0.18 Sn 0.06 ) 3 O and indicated that it can be classified as an n phase.
Restoring Images Degraded by Spatially Variant Blur (1998)

Restoration of images that have been blurred by the effects of a Gaussian blurring function is an ill-posed but well-studied problem. Any blur that is spatially invariant can be expressed as a convolution kernel in an integral equation. Fast and effective algorithms then exist for determining the original image by preconditioned iterative methods. If the blurring function is spatially variant, however, then the problem is more difficult. In this work we develop fast algorithms for forming the convolution and for recovering the original image when the convolution functions are spatially variant but have a small domain of support. This assumption leads to a discrete problem involving a banded matrix. We devise an effective preconditioner and prove that the preconditioned matrix differs from the identity by a matrix of small rank plus a matrix of small norm. Numerical examples are given, related to the Hubble Space Telescope (HST) Wide-Field/Planetary Camera. The algorithms that we develop are applicable to other ill-posed integral equations as well.
In-Space Propulsion High Voltage Hall Accelerator Development Project Overview (2009)

NASA’s Science Mission Directorate In-Space Propulsion Technology Project is funding the development of a high specific impulse long life Hall thruster. The goal of the high voltage Hall accelerator (HiVHAc) project is to develop a flight-like, engineering model (EM) Hall thruster that can meet future NASA science mission requirements. These requirements are met by a thruster that operates over an input power range from 0.3 to 3.5 kW, attains specific impulses from 1,000 to 2,700 seconds, and processes at least 300 kg of xenon propellant at full power. To demonstrate the HiVHAc project goal, two laboratory thrusters have been built and tested. The latest laboratory thruster, the NASA-103M.XL, incorporated a life-extending discharge channel replacement innovation and has been operated for approximately 5,000 hours at a discharge voltage of 700 volts. In 2007, NASA Glenn Research Center teamed with Aerojet to design and manufacture a flight-like HiVHAc EM thruster which incorporated this life-extending channel replacement innovation. The EM thruster was designed to withstand the structural and thermal loads encountered during NASA science missions and to attain performance and lifetime levels consistent with NASA missions. Aerojet and NASA Glenn Research Center have completed the EM thruster design, structural and thermal analysis, fabrication of thruster components, and have assembled and extensively tested one EMl thruster. Performance and thermal characterization of the engineering model thruster has been performed for discharge power levels up to 3.5 kW. The results indicate discharge efficiencies up to of 63% and discharge specific impulse up to 2,930 seconds. In addition to the thruster development, the HiVHAc project is leveraging power processing unit and xenon flow system developments sponsored by other projects but that can apply directly to a HiVHAc system. The goal is to advance the technology readiness level of a HiVHAc propulsion system to 6.
