Experimental demonstration of noncontact pulse wave velocity monitoring using multiple Doppler radar sensors (2010)

In this paper, two Doppler radars are used to monitor the pulse movements at the heart and the calf in order to measure the pulse wave velocity (PWV) wirelessly. Both simulation and experiment have been performed to demonstrate the feasibility of the proposed noncontact PWV monitoring. A three-stage calibration procedure, including DC offset calibration, circuit delay calibration and antenna radiation pattern calibration, has been developed for reliable long-term PWV monitoring. The measurement results have been verified by wired contact measurement with pulse transducers.
Viral RNA annealing activities of human immunodeficiency virus type 1 nucleocapsid protein require only peptide domains outside the zinc fingers. (1992)

The nucleocapsid (NC) of human immunodeficiency virus type 1 consists of a large number of NC protein molecules, probably wrapping the dimeric RNA genome within the virion inner core. NC protein is a gag-encoded product that contains two zinc fingers flanked by basic residues. In human immunodeficiency virus type 1 virions, NCp15 is ultimately processed into NCp7 and p6 proteins. During virion assembly the retroviral NC protein is necessary for core formation and genomic RNA encapsidation, which are essential for virus infectivity. In vitro NCp15 activates viral RNA dimerization, a process most probably linked in vivo to genomic RNA packaging, and replication primer tRNA(Lys,3) annealing to the initiation site of reverse transcription. To characterize the domains of human immunodeficiency virus type 1 NC protein necessary for its various functions, the 72-amino acid NCp7 and several derived peptides were synthesized in a pure form. We show here that synthetic NCp7 with or without the two zinc fingers has the RNA annealing activities of NCp15. Further deletions of the N-terminal 12 and C-terminal 8 amino acids, leading to a 27-residue peptide lacking the finger domains, have little or no effect on NC protein activity in vitro. However deletion of short sequences containing basic residues flanking the first finger leads to a complete loss of NC protein activity. It is proposed that the basic residues and the zinc fingers cooperate to select and package the genomic RNA in vivo. Inhibition of the viral RNA binding and annealing activities associated with the basic residues flanking the first zinc finger of NC protein could therefore be used as a model for the design of antiviral agents.
Cationic Aerosol Photopolymerization (2014)

Abstract Photoinitiated polymerization in aerosols is employed for the preparation of spherical polymer particles via cationic polymerization. The UV irradiation of aerosol monomer droplets starts the cationic curing process without the employment of any solvent or additives such as stabilizers, resulting in highly pure polymers. Crosslinked polymer spheres with a high gel content are obtained by processing vinyl ether and epoxy monomers via this aerosol‐photopolymerization technique, which exhibits great potential for the development of multifunctional materials.
Highly reliable HfSiON CMOSFET with phase controlled NiSi (NFET) and Ni/sub 3/Si (PFET) FUSI gate electrode (2005)

We have clarified that the Ni/Si composition of gate electrode and Hf/Si composition of HfSiON gate insulator are the important parameter to obtain suitable Vth of CMOS. The amount of Hf-Si bonds at the gate/insulator interface is key parameter to control Fermi-level pinning effect. The crystalline phase controlled full Ni-silicide gate (PC-FUSI) and 50% Hf composition HfSiON realize suitable Vth=+/-0.5V with tight distribution. Performance improvement (NFET:1.28 times and PFET:1.52 times) of PC-FUSI FET was also confirmed against poly-Si gate FET with keeping low leakage current. Sufficient long term reliability was also demonstrated through BT stress evaluation.
Multielement spectrometer for efficient measurement of the momentum transfer dependence of inelastic x-ray scattering (2006)

Nonresonant x-ray Raman scattering (XRS) is the inelastic scattering of hard x rays from the K shell of low-Z elements or the less tightly bound shells of heavier elements. In the limit of low momentum transfer q, XRS is determined by the same transition matrix element as is measured by x-ray absorption spectroscopies. However, XRS at higher q can often access higher order multipole transitions which help separate the symmetry of various contributions to the local density of states. The main drawback of XRS is its low cross section—a problem that is compounded for a q-dependent study. To address this issue, we have constructed a multielement spectrometer to simultaneously measure XRS at ten different values of q. By means of example, we report new measurements of the XRS from the L- and K-edges of Mg. This instrument is now available to general users at the Advanced Photon Source as the lower energy resolution inelastic x-ray scattering (LERIX) spectrometer.

Boundary Conditions on Parallel Processing in Human Vision (1989)

A new theory of visual search is tested experimentally with simple colour patches. The essential element of this new theory is that, whatever the search materials, efficiency increases continuously with (i) decreasing similarity between targets and nontargets, and (ii) increasing similarity between one nontarget and another. Control of 'attention' (access to visual short-term memory) is seen as a competitive interaction between display elements, and the theory shows how stimulus similarities influence the outcome of this competition. One alternative view is that parallel visual processes are limited to local mismatch detection. Search is parallel if the target forms a break in an otherwise homogeneous field, but is serial when absolute stimulus identification is required. It is shown, however, that even colour identification can be parallel, providing targets and nontargets are sufficiently dissimilar. A second alternative view is that search for simple features is parallel whereas search for conjunctions is serial. Conjunction search, however, has a characteristic similarity structure: different kinds of nontarget each share one relevant attribute with the target, but none with one another. When this structure is mimicked in search for colour patches, correspondingly poor performance is obtained.
Application Issues for PWM Adjustable Speed AC Motor Drives (1996)

In this article, some application issues for adjustable speed AC motor drives have been investigated. The effects of high PWM frequency, or high dv/dt on the motor terminal voltages and bearing currents have been addressed and explained. Mitigation techniques have been shown to significantly reduce the transient peak voltage and dv/dt at the motor terminals, as well as within the motor windings. This reduction contributes to improved reliability of PWM motor drive systems.
Production and purification of an extracellular polyglucan produced byCellulomonas flavigena strain KU (1990)

A polysaccharide is synthesized byCellulomonas flavigena strain KU when it is cultured in a synthetic medium which uses ammonium salts as a nitrogen source and contains an excess of a carbon and energy source. Production of the polysaccharide begins in late log phase and reaches a maximimum during stationary phase. In batch cultures it may be produced in yields of up to 9 g dry polysaccharide/liter of culture. It is not secreted into the growth medium but rather remains associated with the cells, resulting, apparently, in their aggregation. When such aggregated cells are extracted with dilute sodium hydroxide solutions the polysaccharide is solubilized. Neutralization of supernatant fluid of such extracts results in sedimentation of the polysaccharide which may then be purified by extensive washing with water. The polysaccharide is insoluble in water, alcohols or acetone, but dissolves in concentrated formic acid, dimethyl-sulfoxide, and dilute sodiumor potassium hydroxide. Thin-layer and gas-liquid chromatographic analysis of hydrolysates indicated that it is a polyglucan. When resuspended in water at concentrations of 2–3% it forms a stable hydrogel.
Molecular basis for Duarte and Los Angeles variant galactosemia. (1997)

Human orythrocytes that are homozygous for the Duarte enzyme variant of galactosemia (D/D) have a characteristic isoform on isoelectric focusing and 50% reduction in galactose-1-phosphate uridyltransferase (GALT) enzyme activity. The Duarte biochemical phenotype has a molecular genotype of N314D/N314D. The characteristic Duarte isoform is also associated with a variant called the "Los Angeles (LA) phenotype," which has increased GALT enzyme activity. We evaluated GALT enzyme activity and screened the GALT genes of 145 patients with one or more N314D-containing alleles. We found seven with the LA biochemical phenotype, and all had a 1721C-->T transition in exon 7 in cis with the N314D missense mutation. The 1721C-->T transition is a neutral polymorphism for leucine at amino acid 218 (L218L). In pedigree analyses, this 1721C-->T transition segregated with the LA phenotype of increased GALT activity in three different biochemical phenotypes (LA/N, LA/G, and LA/D). To determine the mechanism for increased activity of the LA variant, we compared GALT mRNA, protein abundance, and enzyme thermal stability in lymphoblast cell lines of D and LA phenotypes with comparable genotypes. GALT protein abundance was increased in LA compared to D alleles, but mRNA was similar among all genotypes. When LA/D and D/D GALT biochemical phenotypes were compared to N/N GALT phenotypes, both had 50%, as compared to 21%, reduction in GALT activity in the wild type (N/N) after exposure at identical initial enzyme activity to 50 degrees C for 15 min. We conclude that the codon change N314D in cis with the base-pair transition 1721C-->T produces the LA variant of galactosemia and that this nucleotide change increases GALT activity by increasing GALT protein abundance without increasing transcription or decreasing thermal lability. A favorable codon bias for the mutated codon with consequently increased translation rates is postulated as the mechanism.
Making a fast curry (2004)

Higher-order languages that encourage currying are implemented using one of two basic evaluation models: push/enter or eval/apply. Implementors use their intuition and qualitative judgements to choose one model or the other.Our goal in this paper is to provide, for the first time, a more substantial basis for this choice, based on our qualitative and quantitative experience of implementing both models in a state-of-the-art compiler for Haskell.Our conclusion is simple, and contradicts our initial intuition: compiled implementations should use eval/apply.
The Unequal Sovereigns of a Slaveholding Land: The North as Subject in Whittier's "The Panorama" (1996)

Although it is probably unprofitable to draw too sharp a distinc tion between Whittier's anti-slavery poetry and his political poetry, one basic criterion for isolating the latter may be that Northern com promisers stand out as the primary object of attack. Such bitingly satirical poems as Haschish or Lines on the Portrait of a Cele brated Publisher deal not with slavery at all but with the apostasy or hypocrisy of the Northern elites. It is therefore all the more signifi cant that Whittier's most important political poem, of 1855, contains prominent anti-slavery passages.1 Indeed, out of this combination grows the true force of the work: its ability to coordinate and confound the contemporary political dispute with the larger questions of political economy raised by the crisis over the fate of the territories. Eric Foner's influential thesis—that the ideology of the Republican party in the pre-Civil War period can be summed up as an attachment to a society based on free labor—has recently been challenged by an historian who assigns greater significance to the Republican fear of the Slave Power as a more narrowly political threat.2 Whittier's poem, however, indicates the interdependence of these two mainsprings of Republican growth by placing the slave system itself at the root of the threats to the North. ' The Panorama s achievements along these lines reveal how Whittier, as a poet long recognized and perhaps discounted by mid century Americans as a member of the political anti-slavery van guard, could help to solidify Republican rhetoric in the crucial years 1854-56, when the new party took full advantage of its best chance to define the terms of political debate in a newly uncertain environ ment. Those terms, if they were to carry the North beyond the unsus tainable outrage over the Kansas-Nebraska Act that had spawned the party, needed to rest on a discourse that bound slavery as a socio economic institution to those specific Southern infringements on
World food trends and prospects to 2025 (1999)

This paper reviews food (especially cereal) production trends and prospects for the world and its main regions. Despite fears to the contrary, in recent years we have seen continued progress toward better methods of feeding humanity. Sub-Saharan Africa is the sole major exception. Looking to the future, this paper argues that the continuation of recent cereal yield trends should be sufficient to cope with most of the demographically driven expansion of cereal demand that will occur until the year 2025. However, because of an increasing degree of mismatch between the expansion of regional demand and the potential for supply, there will be a major expansion of world cereal (and noncereal food) trade. Other consequences for global agriculture arising from demographic growth include the need to use water much more efficiently and an even greater dependence on nitrogen fertilizers (e.g., South Asia). Farming everywhere will depend more on information-intensive agricultural management procedures. Moreover, despite continued general progress, there still will be a significant number of undernourished people in 2025. Signs of heightened harvest variability, especially in North America, are of serious concern. Thus, although future general food trends are likely to be positive, in some respects we also could be entering a more volatile world.
Energy Levels of Iron Group Impurities in TiO<sub>2</sub> (1972)

By changing the location of Fermi level of TiO 2 by lithium doping, ESR signals of some transition metal impurities in this crystal were pursued. The conclusions are: the Cr 3+ , Mn 4+ and Fe 3+ levels are near or overlapped with the valence band, the V 3+ , Mn 2+ and Fe 2+ levels are near the conduction band, the Cr 2+ level is above the bottom of the conduction band, the Mn 3+ and V 4+ levels are near the center of the band gap, and consequently the energy level separation between Mn 2+ and Mn 3+ and that of V 3+ and V 4+ are small ( i. e. less than 2 eV). The calculated level structures with the aid of these experimental results are related to the metallic and insulative nature of magnetic oxides, in general.
Studies in fungitoxicity I.—Fungitoxicity of certain carbocyanines (1957)

Abstract Thirty‐five carbocyanines were examined for fungitoxicity and some were found to be active. This newly found biological property was limited to carbocyanines of a fairly low molecular weight, and was dependent on the heterocyclic base or bases from which the carbocyanine was derived. Alkyl substituents enhanced the fungitoxicity of the dyes irrespective of their position. Tests with some dyes showed that these penetrated to the protoplasts of the spores, staining them irreversibly.
Study on the requirements of joint torque sensors considering mechanical condition of the joint mechanism of a manipulator (2012)

There are many methods to measure the transmitted torque but it is useful to use a joint torque sensor which is equipped between the a flexspline and a link. Even though there exists the friction between them, the finally transmitted torque can be measured, then the measured torque can be used for the feedback torque of the manipulator control algorithm. In this research, we tried to find the requirement for the joint torque sensor. In this paper the experimental results will be introduced.

Perspective: Materials informatics across the product lifecycle: Selection, manufacturing, and certification (2016)

The process of taking a new material from invention to deployment can take 20 years or more. Since the announcement of the Materials Genome Initiative in 2011, new attention has been paid to accelerating this timeframe to address key challenges in industries from energy, to biomedical materials, to catalysis, to polymers, particularly in the development of new materials discovery techniques. Materials informatics, or algorithmically analyzing materials data at scale to gain novel insight, has been lauded as a path forward in this regard. An equal challenge to discovery, however, is the acceleration from discovery to market. In this paper, we address application of an informatics approach to materials selection, manufacturing, and qualification and identify key opportunities and challenges in each of these areas with a focus on reducing time to market for new advanced materials technologies.
Estimation of Q: a comparison of different computational methods (2013)

Summary Four methods of Q estimation are investigated: the spectral-ratio method, a match-technique method, a spectrum modeling method and a time-domain match-filter method. Their accuracy, and the reliability of Q estimation, are evaluated using synthetic data and real VSP data. Testing results demonstrate that the time-domain match-filter method is more robust to noise and more suitable for application to reflection data than the other three methods.
Therapeutic opportunities for liver X receptor modulators. (2004)

The liver X receptors (LXRs), LXRalpha and LXRbeta, are ligand-activated transcription factors of the nuclear receptor superfamily that control the expression of genes involved in cholesterol and fatty acid metabolism. While the identification of small-molecule non-steroidal LXR agonists has validated the LXRs as potential drug targets for cardiovascular disease, recent reports from several research groups suggest that LXR ligands will be valuable therapeutic agents for the treatment of inflammation, diabetes and neurodegenerative diseases. This review focuses on the effects of LXR agonists on relevant signaling pathways, the recently reported ligand-bound LXR crystal structures, and recently disclosed LXR small-molecule templates.

Sidelobe Reduction of Low-Profile Array Antenna Using a Genetic Algorithm (2007)

A low-profile phased array antenna with a low sidelobe was designed and fabricated using a genetic algorithm (GA). The subarray distances were optimized by GA with chromosomes of 78 bits, a population of 100, a crossover probability of 0.9, and a mutation probability of 0.005. The array antenna has 24 subarrays in 14 rows, and is designed as a mobile terminal for Ku-band satellite communication. The sidelobe level was suppressed by 6.5 dB after optimization, compared to the equal spacing between subarrays. The sidelobe level was verified from the far-field pattern measurement by using the fabricated array antenna with optimized distance.

M-Type Pyruvate Kinase Isoforms and Lactate Dehydrogenase A in the Mammalian Retina: Metabolic Implications (2016)

Mammalian photoreceptors contain dimeric and tetrameric PKM2 and LDH-A. This is consistent with the ability to switch between energy production and biosynthesis like a proliferating tissue, possibly due to demands of opsin synthesis.
Two-dimensional IC layout compaction based on topological design rule checking (1990)

An effective approach to two-dimensional compaction of VLSI circuit layouts is discussed. Active devices are described in terms of circular primitives called bubbles. The wires are treated topologically in that no geometric representation is used for them during compaction. This avoids expensive geometrical manipulations of the wires. Cells are compacted by moving bubbles one at a time along design rule preserving paths so as to minimize a cost function directly related to the size of the cell. Geometrical realizations of the wires are reconstructed at the end of the compaction process. The resulting routing has minimum wire length for each wire.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
