Constellations for good diversity performance (1993)

The case in which there are several channels available for transmission, and the additive noise on each channel may have different power, is treated. A signal constellation, called the coordinated code, for the signal space formed by the different channels is presented. The coordinated code has good performance when the noise powers are equal, while simultaneously providing diversity for good performance when the noise powers are unequal, and is relatively simple. The maximum-likelihood receiver is presented; it extracts information from the coded signal in inverse proportion to each channel's noise power. The minimum distance of the code is found, and the coding gain over a system that transmits independent bit streams on each channel is derived as a function of the noise statistics. The gain of the code is also found relative to symbol splitting diversity, which transmits a copy of the same message on each channel; this gain is as high as 9 dB. The code is considered in detail for use with a high rate digital subscriber line (HDSL) comprised of two pairs of a local loop, each pair having different amounts of near end crosstalk (NEXT).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A patient-specific lumped-parameter model of coronary circulation (2018)

A new lumped-parameter model for coronary hemodynamics is developed. This model is developed for the whole coronary network based on CT scans of a patient-specific geometry including the right coronary tree, which is absent in many previous mathematical models. The model adopts the structured tree model boundary conditions similar to the work of Olufsen et al., thus avoiding the necessity of invasive perfusion measurements. In addition, we also incorporated the effects of the head loss at the two inlets of the large coronary arteries for the first time. The head loss could explain the phenomenon of a sudden increase of the resistance at the inlet of coronary vessel. The estimated blood pressure and flow rate results from the model agree well with the clinical measurements. The computed impedances also match the experimental perfusion measurement. The effects of coronary arterial stenosis are considered and the fractional flow reserve and relative flow in the coronary vessels for a stenotic vessel computed in this model show good agreement with published experimental data. It is believed that the approach could be readily translated to clinical practice to facilitate real time clinical diagnosis.
β-Adrenergic, Angiotensin II, and Bradykinin Receptors Enhance Neurotransmission in Human Kidney (1995)

The aim of this study was to investigate angiotensin II (Ang II) receptor-, bradykinin receptor-, and beta-adrenergic receptor-mediated modulation of norepinephrine release from human renal sympathetic nerves and to characterize the respective receptor subtypes involved. Human cortical kidney slices were incubated with [3H]norepinephrine, placed in superfusion chambers between two platinum electrodes, and superfused with Krebs-Henseleit solution. The sympathetic nerves were stimulated electrically at 2.5 Hz for 1 minute, and the stimulation-induced outflow of radioactivity was taken as an index of endogenous norepinephrine release. Ang II and its precursor Ang I (both 0.01 to 1 mumol/L) enhanced stimulation-induced outflow of radioactivity in a concentration-dependent manner, with EC50 values of 0.03 and 0.05 mumol/L, respectively. The enhancement by Ang I but not that by Ang II was inhibited by the angiotensin-converting enzyme inhibitor captopril (3 mumol/L). The concentration-response curves of Ang I and Ang II were shifted to the right by EXP 3174 (0.01 mumol), the in vitro active form of the Ang II type 1 receptor antagonist losartan, with affinity estimates of 8.72 and 9.30, respectively. A higher concentration of EXP 3174 (0.1 mumol/L) abolished the facilitatory effects of Ang I and Ang II. The Ang II type 2 receptor antagonist PD 123319 (10 mumol/L) did not alter the facilitation by Ang II. In the absence of other drugs, bradykinin (0.01 to 1 mumol/L) failed to modulate stimulation-induced outflow of radioactivity but in the presence of captopril (3 mumol/L) enhanced it in a concentration-dependent manner, with an EC50 of 0.1 mumol/L.(ABSTRACT TRUNCATED AT 250 WORDS)

Intact Tissue Assay for Nitrite Reductase in Barley Aleurone Layers (1971)

A method has been devised for the detection and measurement of nitrite reductase activity in intact barley (Hordeum vulgare L. cv. Himalaya) aleurone layers. The technique involves feeding aleurone layers nitrite and measuring nitrite disappearance after a given time period. The method also allows simultaneous determination of nitrite uptake by the tissue. Quantitative recovery of nitrite is obtained by rapid heating of tissue in the presence of dimethyl sulfoxide.Using the procedure described, nitrite reductase activity in intact barley aleurone layers was determined. Enzyme activity was increased by prior incubation of the tissue with nitrate, but considerable activity was present in tissue incubated without nitrate. Nitrate-induced activity was inhibited by cycloheximide but not by actinomycin D. Enzyme activity in induced layers was inhibited by 2,4-dinitrophenol, and partially by antimycin A and 2-n-heptyl-4-hydroxyquinoline N-oxide. Activity in noninduced tissue appeared to be less sensitive to these respiratory inhibitors. In contrast, both activities were inhibited more than 90% by anaerobiosis; but nitrate-induced and noninduced aleurone layers were able to reduce nitrite anaerobically when the concentration of substrate in the assay medium was reduced from 250 mum to 25 mum. Nitrite uptake was relatively insensitive to anaerobiosis and to the inhibitors tested.Nitrite depletion from the medium by aleurone layers was rapid at pH 4.5 and negligible at pH 7.5. Nitrite accumulated at pH 4.5 under anaerobic conditions was rapidly released when the tissue was transferred to medium at pH 7.5. Nitrite release at pH 7.5 occurred whether the tissue was maintained under anaerobic or aerobic conditions.

Cutting edge Micro-display High Definition Televisions have the capability to display high resolution images at high update rates. The next capability on the horizon to enhance the viewing experience of High Definition Televisions is the ability to display stereoscopic images and video content. This paper discusses the implementation of a Micro-Display High Definition Television, capable of displaying stereoscopic images and video content with the aid of high contrast shutter glasses. It also introduces another new feature called DualView.
A Calibration Circuit for Reconfigurable Smart ADC for Biomedical Signal Processing (2010)

Reconfigurable analog-to-digital converters (ADC) have been receiving increased attention in the research community for the capability to adapt to continuously varying signal processing requirements. The reconfigurable ADC is particularly advantageous in implantable biomedical sensor signal processing systems that processes signal in different range of frequency and amplitude levels and has low power consumption constraints. In this work a calibration circuit is presented that analyses the input signal from biomedical sensors and based on the dynamic range and frequency of the signal generates a two-bit control signal to change the configuration of the ADC for optimum resolution and power consumption. The two-bit control signal reconfigures the 10-bit 40MSPS pipeline ADC to operate in four different configurations by changing resolution, sampling clock and bias current for optimized operation. The calibration circuit is designed in 90 nm process and requires only 36.9μA current with 1V power supply and occupies 0.0054mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> chip area.

Pain in prostate cancer patients with and without metastases (1997)

The study examined the nature of pain associated with localized or metastatic prostate cancer (PC). Fourteen men with localized PC, 18 with PC and bony metastases, and a comparison group of 117 patients with rheumatoid arthritis (RA), completed the body drawing and the pain vocabulary of the McGill Pain Questionnaire (MPQ). There were no significant differences in Pain Rating Index (PRI) between the three groups. The choice of pain adjectives did not differentiate between localized and metastatic PC. Chi-squared analysis revealed group differences in the number of times each PRI subclass was employed to describe localized and metastatic PC pain. In contrast, the frequency of choosing PRI subclasses to describe metastatic PC and RA pain was similar. The results suggested: (i) that bony qualities were included in the description of pain associated with metastatic PC, and (ii) pain assessment conducted at different stages of PC could assist in the management of PC pain.
Research and Application of Code Similarity Based on Submission (2020)

<p>With the continuous accumulation of resources, the similarity detection of code is becoming more difficult, and the difficulty of code reusing and rechecking is also increasing. In view of this problem, this paper proposes a code recommendation and check-research based on submission, which uses differential code cloning and word vector methods to find candidate code sets that are similar to incremental text, and uses feature extraction and clustering to select the most relevant codes from the candidate code sets to obtain repetitive codes. At the same time, it is recommended to programmers combined with relevance scores. Experimental results show that this method is feasible to some extent.</p>
Symmetry in Cascade Chirality-Transfer Processes: A Catalytic Atroposelective Direct Arylation Approach to BINOL Derivatives (2016)

Herein we disclose a scalable organocatalytic direct arylation approach for the regio- and atroposelective synthesis of non-C2-symmetric 2,2'-dihydroxy-1,1'-binaphthalenes (BINOLs). In the presence of catalytic amounts of axially chiral phosphoric acids, phenols and naphthols are coupled with iminoquinones via a cascade process that involves sequential aminal formation, sigmatropic rearrangement, and rearomatization to afford enantiomerically enriched BINOL derivatives in good to excellent yields. Our studies suggest that the (local) symmetry of the initially formed aminal intermediate has a dramatic impact on the level of enantioinduction in the final product. Aminals with a plane of symmetry give rise to BINOL derivatives with significantly lower enantiomeric excess than unsymmetrical ones featuring a stereogenic center. Presumably asymmetric induction in the sigmatropic rearrangement step is significantly more challenging than during aminal formation. Sigmatropic rearrangement of the enantiomerically enriched aminal and subsequent rearomatization transfers the central chirality into axial chirality with high fidelity.
Vibration Sensitivity of MEMS Tuning Fork Gyroscopes (2007)

MEMS tuning fork gyroscopes (TFGs) are known to be relatively immune to vibrations due to their differential operation and common-mode rejection. However, even a perfectly-matched TFG cannot completely eliminate vibrations due to vibration-induced asymmetry and nonlinearity. We select two commonly used gyroscope structures and analyze their vibration characteristics. Both structures employ decoupled sense and drive masses with "Type-A" having an anchored sense mass and "Type-B" having an anchored drive mass. To understand the effects of vibration on these two structures, we performed nonlinear dynamic simulations using MATLAB and SIMULINK. The results show that Type-B structures are insensitive to vibrations (>99% reduction) when compared to Type-A structures. In addition, the simulations reveal the dominant vibration characteristics for each structure.
Hole trapping phenomena in the gate insulator of As-fabricated insulated gate field effect transistors (1990)

Hole trapping phenomena in SiO2 were examined using an optically assisted hot carrier injection technique on p-channel insulated gate field effect transistors. It was found that only a single, field-dependent, capture-cross-section hole trap is present. The capture cross section of these hole traps at a field of 4 mV/cm across the gate insulator, corresponding to a gate voltage just above the threshold voltage, was found to be 8.5×10−14 cm2. Injected holes were found to trap with an initial efficiency of approximately 60% at this gate field. Depopulation of trapped holes at room temperature was also examined, and found to be significant. The neutral hole trap density in unirradiated device gate insulators after post-metal annealing was found to be approximately 7.0×1012 cm−2. Based on a study of the threshold voltage shift as a function of gate insulator thickness, coupled with the model recently proposed by Walters and Reisman for determining charge centroid, it appears that for oxides with thicknesses greater than 10 nm, the hole traps lie in a band of finite thickness with a charge centroid 5 nm from the substrate-SiO2 interface. In addition, there exists a layer approximately 3.7 nm thick at each interface that appears void of trapped charge. Therefore, oxides less than 7.4 nm thick should not trap charge, which was found to be the case experimentally. This implies that as devices are scaled down, hole trapping will disappear, which is of particular significance in oxides subjected to ionizing irradiation, either during processing or during use.
Noise reduction for periodic signals using high-resolution frequency analysis (2011)

Abstract The spectrum subtraction method is one of the most common methods by which to remove noise from a spectrum. Like many noise reduction methods, the spectrum subtraction method uses discrete Fourier transform (DFT) for frequency analysis. There is generally a trade-off between frequency and time resolution in DFT. If the frequency resolution is low, then the noise spectrum can overlap with the signal source spectrum, which makes it difficult to extract the latter signal. Similarly, if the time resolution is low, rapid frequency variations cannot be detected. In order to solve this problem, as a frequency analysis method, we have applied non-harmonic analysis (NHA), which has high accuracy for detached frequency components and is only slightly affected by the frame length. Therefore, we examined the effect of the frequency resolution on noise reduction using NHA rather than DFT as the preprocessing step of the noise reduction process. The accuracy in extracting single sinusoidal waves from a noisy environment was first investigated. The accuracy of NHA was found to be higher than the theoretical upper limit of DFT. The effectiveness of NHA and DFT in extracting music from a noisy environment was then investigated. In this case, NHA was found to be superior to DFT, providing an approximately 2 dB improvement in SNR.
High-Resolution NMR of an Antisense DNA·RNA Hybrid Containing Alternating Chirally Pure <i>R</i><sub>p</sub> Methylphosphonates in the DNA Backbone (1997)

A high-resolution proton NMR study has been performed on a hybrid duplex formed by a methylphosphonate (MP) oligodeoxyribonucleotide (MPO) and its target oligoribonucleotide, d(T(MP)CC(MP)-TT(MP)AG(MP)CT(MP)CC(MP)TG) x r(CAGGAGCUAAGGA), where MP corresponds to positions of methylphosphonate linkages in the pure R(p) stereoconfiguration. MP-containing analogs of DNA are reported to be effective antisense agents capable of specifically inhibiting protein synthesis with the R(p) chiral MPOs exhibiting greater affinity for the target mRNA than their S(p) counterparts. Nearly complete proton resonance assignments of the hybrid duplex have been made using two-dimensional nuclear Overhauser effect (2D NOE) spectra, at three different mixing times, and double quantum-filtered COSY (2QF-COSY) spectra. The 2QF-COSY cross-peak patterns which are resolved have been analyzed qualitatively to suggest sugar conformations. Distance restraints have been obtained from the 2D NOE spectra of the duplex in D(2)O. These interproton distance restraints were determined using a complete relaxation matrix method to improve accuracy. Specifically, a new approach termed RANDMARDI has been utilized to calculate these distance restraints, accounting for spectral noise and errors in 2D NOE peak volume integration. The calculated interproton distances and sugar puckers have been analyzed to assess the solution conformation of the hybrid. The hybrid duplex appears to have an overall solution structure which is distinct from standard B- and A-forms, but the RNA strand exhibits features of the A-form. The absence of H1'-H2' cross-peaks in the 2QF-COSY spectrum indicates a C3'-endo type of conformation for ribose sugars in the RNA strand. The deoxyriboses in the antisense DNA strand exhibit a mixed behavior with almost equal scalar coupling constant values for H1'-H2' and H1'-H2" and a strong H3'-H4' 2QF-COSY peak pattern. Variations in calculated values of interproton distances and sixth-root R factor analysis of experimental intensities indicate that the hybrid duplex may have a DNA strand with significant conformational plasticity.

Detailed Folding Structures of Kappa-conotoxin RIIIJ and Its Mutageneses Obtained from 2-Dimensional HP Model (2012)

Kappa-conotoxin RIIIJ is a conopeptide to inhibit voltage-gated potassium channels, however, its detailed folding structures have yet to be studied. With the advance in computing power, it is possible to use the HP model to analyze all its possible folding structures. In this study, the amino acid sequences of kappa-conotoxin RIIIJ and its four mutageneses were converted into ten HP sequences according to the normalized hydrophobicity index. All 282 429 536 481 possible folding structures in each HP sequence were found using the 2-dimensional HP model, and the detailed folding structures at native state were studied. The results showed that kappa-conotoxin RIIIJ had 180 and 90 folding structures at their native state with minimal energy of -9 and -10 at pH 2 and pH 7; its mutagenesis (6-8) TPP - > SLN increased the numbers of the folding structures to 456 and 564 at pH 2 and pH 7; whereas its mutageneses (6-11) TPPKKH - > SLNLRL, (9- 11) KKH - > LRL, and (10-11) KH - > RL decreased the numbers of the folding structures to 60, 30 and 90 at both pH levels, respectively. Thereafter, the normalized hydrophobicity index was employed to distinguish those native states, and attempts were made to explain the effect of mutageneses on potassium channels in terms of the number of folding structures and numerical native states.
Apolipoprotein C3 gene variants and the risk of coronary heart disease: A meta-analysis (2016)

The pooled evidence suggests that two SNPs (SstI and T-455C) are associated with an increased risk of CHD. However, because of the limited sample size and heterogeneity, further large-scale and well-designed studies are needed to validate our findings.
A Study of the Angle of Inclination and Facet Curvature of Superior Lumbar Zygapophyseal Facets (1993)

The angle of inclination and depth of curvature of L1-L5 of the superior articular facets of both sexes were measured in 112 lumbar spines. In addition to standard statistical methods data were also analyzed to show various degrees of departure from the "normal." The L3 vertebra showed the least variation and L5 and L1 showed the most. The angle and depth of L1 to L5 showed a small, albeit statistically significant, difference between the two sexes but no laterality differences were apparent. At L1 12.5% of males and 10.4% of females revealed an asymmetry of angle exceeding 20, and at L5 3.1% of males and 1.7% of females showed such tendency. An asymmetry of the depth of curvature of the articular facets exceeding 1.5 mm was recorded in 12.5% of males and 8.3% of females at L1 and 6.5% of males and 2.1% females at L5. The expected values of depth of curvature were lowest at L1 and highest at L3 and L4. It is suggested that a more quantitative approach to the study of the zygapophyseal joint would enhance precision and facilitate meaningful interlaboratory comparisons of published data.
Magnetically driven isentropic compression to multimegabar pressures using shaped current pulses on the Z accelerator (2005)

A technique has previously been developed on the Z accelerator [R. B. Spielman et al., Phys. Plasmas 5, 2105 (1998)] to generate ramped compression waves in condensed matter for equation-of-state studies [C. A. Hall, J. R. Asay, M. D. Knudson, W. A. Stygar, R. B. Spielman, T. D. Pointon, D. B. Reisman, A. Toor, and R. C. Cauble, Rev. Sci. Instrum. 72, 3587 (2001)] by using the Lorentz force to push on solid electrodes rather than to drive a Z pinch. This technique has now been extended to multimegabar pressures by shaping the current pulse on Z to significantly increase the sample thickness through which the compression wave can propagate without forming a shock. Shockless, free-surface velocity measurements from multiple sample thicknesses on a single experiment can be analyzed using a backward integration technique [D. B. Hayes, C. A. Hall, J. R. Asay, and M. D. Knudson, J. Appl. Phys. 94, 2331 (2003)] to extract an isentropic loading curve. At very high pressures, the accuracy of this method is dominated by relative uncertainty in the transit time between two thicknesses. This paper discusses in some detail the issues involved with accurate measurement of a multimegabar isentrope, including experiment design trade-offs and mechanics of pulse shaping on Z.
