High resolution patterning of silicon by selective gallium doping (1983)

High resolution patterns have been fabricated in 〈100〉 silicon by doping selected areas with gallium utilizing an ion microprobe. These doped regions are used as an etch mask for subsequent anisotropic etching of silicon. The etching was performed in a KOH:IPA solution at 80–90 °C. The resulting etch rate of the doped silicon is approximately inversely proportional to the gallium impurity concentration. At high doping concentrations an etch rate difference of greater than 1000:1 has been measured between the virgin silicon and the doped regions. Using this technique features as small as 30 nm have been produced.
Distortion improvement of lossless feedback amplifiers using augmentation (2003)

A method for improving the distortion characteristics of a class of lossless feedback amplifiers is described, consisting of amplifying and inverting the error voltage at the emitter of the common-base transistor and applying the amplified error voltage to the transistor base. Descriptions are included for active and passive realizations.
Bar Coding An Effective Productivity Concept (1991)

Bar coding is becoming a major contributor to the information revolution taking place in the health-care industry. Besides improving nursing productivity, bar coding can improve the quality of documentation and enhance the manner in which staffing requirements are identified and patient classification information gathered.
Role of the 1-72 base pair in tRNAs for the activity of<i>Escherichia coli</i>peptidyl-tRNA hydrolase (1993)

Previous work by Schulman and Pelka (1975) J. Biol. Chem. 250, 542-547, indicated that the absence of a pairing between the bases 1 and 72 in initiator tRNA(fMet) explained the relatively small activity of peptidyl-tRNA hydrolase towards N-acetyl-methionyl-tRNA(fMet). In the present study, the structural requirements for the sensitivity of an N-acetyl-aminoacyl-tRNA to Escherichia coli peptidyl-tRNA hydrolase activity have been further investigated. Ten derivatives of tRNA(fMet) with various combinations of bases at positions 1 and 72 in the acceptor stem have been produced, aminoacylated and chemically acetylated. The release of the aminoacyl moiety from these tRNA derivatives was assayed in the presence of peptidyl-tRNA hydrolase purified from an overproducing strain. tRNA(fMet) derivatives with either C1A72, C1C72, U1G72, U1C72 or A1C72 behaved as poor substrates of the enzyme, as compared to those with C1G72, U1A72, G1C72, A1U72 or G1U72. With the exception of U1G72, it could be therefore concluded that the relative resistance of tRNA(fMet) to peptidyl-tRNA hydrolase did not depend on a particular combination of nucleotides at positions 1 and 72, but rather reflected the absence of a base pairing at these positions. In a second series of experiments, the unpairing of the 1 and 72 bases, created with C-A or A-C bases, instead of G-C in methionyl-tRNA(mMet) or in valyl-tRNA(Val1), was shown to markedly decrease the rate of hydrolysis catalysed by peptidyl-tRNA hydrolase. Altogether, the data indicate that the stability of the 1-72 pair governs the degree of sensitivity of a peptidyl-tRNA to peptidyl-tRNA hydrolase.
Generation of a human monoclonal antibody to hepatitis C virus, JRA1 by activation of peripheral blood lymphocytes and hypo-osmolar electrofusion (1995)

We have generated a human monoclonal antibody with binding specificity for hepatitis C virus (HCV)-specific peptides using peripheral blood lymphocytes isolated from a HCV antibody positive patient. The B-lymphocytes were stimulated with lipopolysaccharide (LPS) for 72 hours prior to the fusion. A recently described high efficiency hypo-osmolar electrofusion technique was employed, allowing generation of a large number of human hybridomas. The hybridomas were screened for human immunoglobulin and HCV-specific peptide binding by EIA. A single HCV-positive clone, JRA1, was detected and sub-cloned. Isotype analysis showed it to secrete an IgM lambda monoclonal antibody. The antibody was positive on both first and second generation HCV antibody analysis. This study confirms that viable pathogen-specific B-cells may be recovered from the peripheral blood. Although such cells are likely to be relatively uncommon in the circulating B-cell pool, they may be successfully immortalized by high efficiency electrofusion techniques. This technique might be valuable for the generation of human monoclonal antibodies with specificity for other human pathogens.
An Efficient Architecture and Algorithm for Resource Provisioning in Fog Computing (2016)

Cloud computing is a model of sharing computing resources over any communication network by using virtualization. Virtualization allows a server to be sliced in virtual machines. Each virtual machine has its own operating system/applications that rapidly adjust resource allocation. Cloud computing offers many benefits, one of them is elastic resource allocation. To fulfill the requirements of clients, cloud environment should be flexible in nature and can be achieve by efficient resource allocation. Resource allocation is the process of assigning available resources to clients over the internet and plays vital role in Infrastructure-as-a-Service (IaaS) model of cloud computing. Elastic resource allocation is required to optimize the allocation of resources, minimizing the response time and maximizing the throughput to improve the performance of cloud computing. Sufficient solutions have been proposed for cloud computing to improve the performance but for fog computing still efficient solution have to be found. Fog computing is the virtualized intermediate layer between clients and cloud. It is a highly virtualized technology which is similar to cloud and provide data, computation, storage, and networking services between end users and cloud servers. This paper presents an efficient architecture and algorithm for resources provisioning in fog computing environment by using virtualization technique.
The Application of Computer-Based Techniques to the Development of Injury Severity Indices * (1981)

During the last decade, the authors have developed a comprehensive set of triage, hospital admission, and organ-specific indices which characterize the severity of patient state. The indices are based on physiological and biochemical measurements and anatomical assessments of patients from several medical centers. The role of the computer in the development and implementation of these indices for patient triage and tracking, and for evaluation of patient care will be discussed in this paper.
Visible-Light-Driven Photoproduction of Hydrogen Using Rhodium Catalysts and Platinum Nanoparticles with Formate (2014)

Photochemical hydrogen production is carried out using molecular Rh complexes and sodium formate in the presence of platinum nanoparticles (PtNPs) in aqueous buffer solution. Visible-light-driven photocatalytic reactions for hydrogen production with and without nicotinamide adenine dinucleotide (NAD+) follow two different pathways. Complex [Cp*Rh(bpy)(OH2)]2+ selectively reduces NAD+ to generate NADH using formate as a proton and electron donor and the chemically generated NADH is sequentially used by PtNPs upon photoactivation of eosin Y to produce hydrogen. However, hydrogen is also produced in photoreactions of the Rh catalyst and PtNPs with formate in the absence of NAD+ and eosin Y. The second pathway for hydrogen production was performed under the conditions without NAD+ and eosin Y and derived from a direct electron transfer from in situ generated rhodium(III)-hydride species to photoexcited PtNPs. The direct electron transfer from the rhodium-hydride species to visible-light-driven PtNPs was first observed in this study. These two pathways for hydrogen production showed different rate-limiting steps based on a Hammett plot using Rh catalysts containing electron-donating and electron-withdrawing groups. Kinetic isotope effects as well as Hammett plot supported the rate-limiting step of the NADH generation for the first pathway of hydrogen production and the Rh–H formation for the second pathway.
A flat diversity antenna by disk loaded monopole and notch array (1992)

The authors present a novel flat antenna consisting of a disk loaded monopole and a notch array for mobile telephone. To obtain a small correlation coefficient between the notch array and the disk loaded monopole antenna, two feed circuits are proposed for the notch array. The correlation coefficient between ring patch and notch antenna of less than 0.1 is small enough for diversity branches.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Investigation of the Parasitic Coupling Effects in Densely Packaged RSFQ Digital Circuits (2005)

The Rapid Single Flux Quantum (RSFQ) technique is regarded as one of the most promising electronics due to its extremely high operating speed and low power consumption. Middle-scale RSFQ applications operating at multigigahertz frequency have recently been reported on. At such high operating frequencies, the on-chip interconnects start to play a limiting role for the performance of the densely packaged digital circuits. Our previous studies have theoretically investigated the parasitic coupling effects between superconductive microstrip transmission lines and conclusions have been drawn about the critical coupling levels of several typical microstrip geometries. Here, basic RSFQ structures are investigated experimentally, which contain a Josephson transmission line stage with large inductance and can either trap or pass SFQ pulses. These structures are incorporated in critical microstrip layouts, thus being subjected to parasitic coupling. The bias levels are monitored at which the structures start to pass the SFQ pulses with and without coupling influences. Thus, the conclusions of our previous theoretical investigations are verified experimentally.

DPOAE level mapping for detecting noise-induced cochlear damage from short-duration music exposures (2015)

Distortion product otoacoustic emission (DPOAE) level mapping provides a comprehensive picture of cochlear responses over a range of DP frequencies and f₂/f₁ratios. We hypothesized that individuals exposed to high-level sound would show changes detectable by DPOAE mapping, but not apparent on a standard DP-gram. Thirteen normal hearing subjects were studied before and after attending music concerts. Pure-tone audiometry (500-8,000 Hz), DP-grams (0.3-10 kHz) at 1.22 ratio, and DPOAE level maps were collected prior to, as soon as possible after, and the day after the concerts. All maps covered the range of 2,000-6,000 Hz in DP frequency and from 1.3 to -1.3 in ratio using equi-level primary tone stimuli. Changes in the pure-tone audiogram were significant (P ≤ 0.01) immediately after the concert at 1,000 Hz, 4,000 Hz, and 6,000 Hz. The DP-gram showed significant differences only at f₂= 4,066 (P = 0.01) and f₂= 4,348 (P = 0.04). The postconcert changes were readily apparent both visually and statistically (P ≤ 0.01) on the mean DP level maps, and remained statistically significantly different from baseline the day after noise exposure although no significant changes from baseline were seen on the DP-gram or audiogram the day after exposure. Although both the DP-gram and audiogram showed recovery by the next day, the average DPOAE level maps remained significantly different from baseline. The mapping data showed changes in the cochlea that were not detected from the DP-gram obtained at a single ratio. DPOAE level mapping provides comprehensive information on subtle cochlear responses, which may offer advantages for studying and tracking noise-induced hearing loss (NIHL).

110名の患者に対し経皮的腎尿管切石術を施行し, 腎結石89個中88個 (99%) および尿管結石31個中24個 (77%) を摘出した. 腎結石の15例と尿管結石の3例において残石を認めたが全例臨床的には満足のいく結果を得た. 初期の鋳型結石3症例を含む4症例で輸血を必要とした出血を, またその内1例で自然治癒した著しい腎周囲血腫を認めた他は特記すべき合併症はなかった.鋳型結石9例を含む大きい結石の破砕, 摘出に Mazzariello-Caprini 鉗子とコツヘル鉗子が有用で, 二期的に行えば出血も問題なく術後の腎機能も良好であった.また脆くない20～30×15×10mm程度までの大きさの結石は破砕せず鉗子操作によりそのまま摘出でき, 破砕器により破砕し摘出する方法に比し, (1) 結石の破片を残す危険性が低い, (2) 結石中の細菌による汚染がない, (3) 手術時間が著しく短縮される, (4) 高価な医療器械を必要としない, (5) 灌流液の吸収による副作用がない. などの利点があると考えられた.
An anatomical three‐dimensional study of the posteromedial corner of the knee (2011)

Posteromedial corner ligament structures are quite complex and are not always clearly described in the literature. Three-dimensional images of these structures can help better understanding its anatomy.
Genetic evidence from two families that the apolipoprotein B gene is not involved in abetalipoproteinemia. (1988)

Abetalipoproteinemia (ABL) is a recessive disorder in which affected individuals have extremely low or undetectable levels of serum apo B-containing lipoproteins. Using restriction fragment length polymorphisms, we have studied two families, each with two children with classical ABL born of normal parents. In each of these families, the two affected children have inherited different apo B alleles from at least one parent, whereas the siblings would be anticipated to share common alleles if this disorder were due to an apo B gene mutation. This linkage study shows that in these families, the apo B gene is discordant with ABL and therefore the disorder is caused by a defect in another gene, which is important for the normal synthesis or secretion of apo B-containing lipoproteins from both the liver and intestine.

<i>In vitro</i> and <i>in vivo</i> neuroprotective activity of the cardiac glycoside oleandrin from <i>Nerium oleander</i> in brain slice‐based stroke models (2011)

The principal active constituent of the botanical drug candidate PBI-05204, a supercritical CO(2) extract of Nerium oleander, is the cardiac glycoside oleandrin. PBI-05204 shows potent anticancer activity and is currently in phase I clinical trial as a treatment for patients with solid tumors. We have previously shown that neriifolin, which is structurally related to oleandrin, provides robust neuroprotection in brain slice and whole animal models of ischemic injury. However, neriifolin itself is not a suitable drug development candidate and the FDA-approved cardiac glycoside digoxin does not cross the blood-brain barrier. We report here that both oleandrin as well as the full PBI-05204 extract can also provide significant neuroprotection to neural tissues damaged by oxygen and glucose deprivation as occurs in ischemic stroke. Critically, we show that the neuroprotective activity of PBI-05204 is maintained for several hours of delay of administration after oxygen and glucose deprivation treatment. We provide evidence that the neuroprotective activity of PBI-05204 is mediated through oleandrin and/or other cardiac glycoside constituents, but that additional, non-cardiac glycoside components of PBI-05204 may also contribute to the observed neuroprotective activity. Finally, we show directly that both oleandrin and the protective activity of PBI-05204 are blood brain barrier penetrant in a novel model for in vivo neuroprotection. Together, these findings suggest clinical potential for PBI-05204 in the treatment of ischemic stroke and prevention of associated neuronal death.
The overexpression and complete amino acid sequence of <i>Escherichia coli</i> 3-dehydroquinase (1986)

The enzyme 3-dehydroquinase was purified in milligram quantities from an overproducing strain of Escherichia coli. The amino acid sequence was deduced from the nucleotide sequence of the aroD gene and confirmed by determining the amino acid composition of the overproduced enzyme and its N-terminal amino acid sequence. The complete polypeptide chain consists of 240 amino acid residues and has a calculated subunit Mr of 26,377. Transcript mapping revealed that aroD is a typical monocistronic gene.
Improvement of the emission characteristics of a multicore fiber laser using self reproduction in a multimode interference device (MMI) (2002)

Summary form only. The development of high power diode-pumped fiber lasers for cw or pulsed applications requires a good transfer of pump-to-fiber laser radiation, a high slope efficiency and management of thermal problems. For high power solitary femtosecond fiber lasers the chirp parameter should be small combined with a proper value of the group velocity dispersion. To have decided to use a multitude of doped monomode fibers (61) confined within a common pump core of large diameter (multicore fiber). We show that using a multimode interference device (MMI) being made up of a step index multimode fiber coupled to the multicore fiber the uncorrelated emission may be influenced via field reconstruction.
Extensible Authentication Protocol (EAP) Attributes for Wi-Fi Integration with the Evolved Packet Core (2015)

With Wi-Fi emerging as a crucial access network for mobile service providers, it has become important to provide functions commonly available in 3G and 4G networks in Wi-Fi access networks as well.Such functions include Access Point Name (APN) Selection, multiple Packet Data Network (PDN) connections, and seamless mobility between Wi-Fi and 3G/4G networks.The EAP Authentication and Key Agreement (EAP-AKA), and EAP-AKA', protocol is required for mobile devices to access the mobile Evolved Packet Core (EPC) via Wi-Fi networks.This document defines a few new EAP attributes to enable the above-mentioned functions in such networks.The attributes are exchanged between a client (such as a Mobile Node (MN)) and its network counterpart (such as an Authentication, Authorization, and Accounting (AAA) server) in the service provider's infrastructure.
An Investigation Of Computed Tomography (CT) Linearity (1985)

The linear dependence of Computed Tomography (CT) numbers on linear attenuation coefficients was investigated. CT numbers were fit to linear attenuation coefficients using the least squares method for energies from 55 to 80 keV. The variance was recorded. The energy representing the lowest variance was assumed to be the effective energy of the scanner. Six points were insufficient to unambiguously define the effective energy. Nine materials were used in all subsequent studies; unambiguous values were obtained. Linearity was determined as a function of field of view, phantom size from 10 cm to 30 cm diameter, and energy. Two plastics (polysulfone and acetal) are described which extend the linearity curve to 215 and 360 Houndsfield numbers respectively (scale is 1000). Practical applications were investigated.
Exogenous and Endogenous Adenosine Inhibits Fetal Calf Serum–Induced Growth of Rat Cardiac Fibroblasts (1997)

Cardiac fibroblasts synthesize adenosine, and exogenous and cardiac fibroblast-derived adenosine inhibits cardiac fibroblast proliferation via activation of A2B receptors. Cardiac fibroblast-derived adenosine may regulate cardiac hypertrophy and/or remodeling by modulating cardiac fibroblast proliferation.
[Study on the photofluorescence of Eu(III) and long chain fatty acid complexes]. (2002)

The complexes having the compositions of Eu(L1)(3)2H2O,Eu(L1)3phen,Eu(L2)(3)2H2O,Eu(L2)3phen (phen = 1,10-phenathroline,L1 = Dodecanoic acid, L2 = Stearic acid) were synthesized and characterized by elemental analysis and FTIR spectra. Their fluorescence spectra, UV spectra and TEM (Transmission Electron Microscope) have been investigated. The results show that the 5D0-7F1 and 5D0-7F2 transition of Eu(III) are observed in the emission spectrum of the particles at room temperature. As good photoluminescent materials, they may be useful in the regions of EL (Electroluminescence) or macromolecule composite materials doped with rare earth.
Frequency of Peripherally Inserted Central Catheter Complications in Children (2011)

This study examined the frequency and types of complications with peripherally inserted central catheters (PICCs) placed in immunocompetent pediatric patients for parenteral antimicrobial therapy. It also sought to determine risk factors associated with those complications. Complications occurred at a frequency of 19.3/1000 PICC days, and greater than 30% of PICCs developed at least one complication. Risk factors for complication include double-lumen PICCs, PICCs placed in the femoral vein, younger age, and greater number of daily doses.
Studies of the Liquid-Liquid Partition Systems. IV. The Solvent Extraction Study of Europium(III) Adduct Chelate Complexes with Six Acetylacetone Derivatives and Tributylphosphate (1965)

Abstract The extraction of europium(III) in 0.1 m sodium perchlorate with acetylacetone, benzoylacetone, trifluoroacetylacetone, benzoyltrifluoroacetone, froyltrifluoroacetone and thenoyltrifluoroacetone in chloroform and the adduct formation of these metal chelates with tributylphosphate have been studied at 25°C. It has been concluded that: (i) The β-diketones which have one trifluoromethyl group extract europium(III) better than those which have no trifluoromethyl group. The difference in the metal extraction with acetylacetone or trifluoroacetylacetone and the metal extraction with the homologues of these β-diketones seems to be mainly due to the aqueous chelate complex formation, (ii) A metal chelate with a β-diketone which has a trifluoromethyl group is a much better acceptor of tributylphosphate to form adduct complexes than a metal chelate with a β-diketone which has no trifluoromethyl group. (iii) The ability of the acetylacetone chelate or the trifluoroacetylacetone chelate to form an adduct is not very much changed by the replacement of the methyl group with a benzoyl, froyl, or thenoyl group.
