Why I am optimistic about the silicon-photonic route to quantum computing (2016)

This is a short overview explaining how building a large-scale, silicon-photonic quantum computer has been reduced to the creation of good sources of 3-photon entangled states (and may simplify further). Given such sources, each photon need pass through a small, constant, number of components, interfering with at most 2 other spatially nearby photons, and current photonics engineering has already demonstrated the manufacture of thousands of components on two-dimensional semiconductor chips with performance that allows the creation of tens of thousands of photons entangled in a state universal for quantum computation. At present the fully-integrated, silicon-photonic architecture we envisage involves creating the required entangled states by starting with single-photons produced non-determistically by pumping silicon waveguides (or cavities) combined with on-chip filters and nanowire superconducting detectors to herald that a photon has been produced. These sources are multiplexed into being near-deterministic, and the single photons then passed through an interferometer to non-deterministically produce small entangled states - necessarily multiplexed to near-determinism again. This is followed by a `ballistic' scattering of the small-scale entangled photons through an interferometer such that some photons are detected, leaving the remainder in a large-scale entangled state which is provably universal for quantum computing implemented by single-photon measurements. There are a large number of questions regarding the optimum ways to make and use the final cluster state, dealing with static imperfections, constructing the initial entangled photon sources and so on, that need to be investigated before we can aim for millions of qubits capable of billions of computational time-steps. The focus in this article is on the theoretical side of such questions.

Parallel-interference-cancellation-assisted decision-directed channel estimation for OFDM systems using multiple transmit antennas (2005)

The number of transmit antennas that can be employed in the context of least-squares (LS) channel estimation contrived for orthogonal frequency division multiplexing (OFDM) systems employing multiple transmit antennas is limited by the ratio of the number of subcarriers and the number of significant channel impulse response (CIR)-related taps. In order to allow for more complex scenarios in terms of the number of transmit antennas and users supported, CIR-related tap prediction-filtering-based parallel interference cancellation (PIC)-assisted decision-directed channel estimation (DDCE) is investigated. New explicit expressions are derived for the estimator's mean-square error (MSE), and a new iterative procedure is devised for the offline optimization of the CIR-related tap predictor coefficients. These new expressions are capable of accounting for the estimator's novel recursive structure. In the context of our performance results, it is demonstrated, for example, that the estimator is capable of supporting L=16 transmit antennas, when assuming K=512 subcarriers and K/sub 0/=64 significant CIR taps, while LS-optimized DDCE would be limited to employing L=8 transmit antennas.
Dynamics of Wind Strength and Wind Direction on Air Pollution Dispersion (2016)

The aim of the study is to examine the wind dynamics of Ota to understand certain atmospheric influences. An average volume of about four hundred and eighty thousand (480,000) wind speed data from the Davis weather station data logger of the department of physics, covenant university were considered. The data studied were divided into eight hour period, namely, night time (10pm to 6am following day); day time (6am to 2pm) and noon/evening time (2pm to 10pm). Of the three periods studied, wind speed at night time was observed to be the least. December, January and February (DJF) data set was statistically analyzed. The correlation coefficient values recorded with the wind flow for the months of DJF are 0.28 for December, 2012, 0.20 for January, 2013, and 0.39 for February, 2013. While a significant low correlation coefficient values observed for the months of March, April and May (MAM) are 0.02 for March, 0.01 for April and 0.04 for May. A further daily analysis was conducted for February. A significant occurrence of atmospheric stagnation was observed in the night time readings of February 3, 2013 with an exceptional low average wind speed of 0.143 ms-1. While February 17, 2013 recorded all day normal air ventilation with wind speed of 1.443 ms-1, 1.998 ms-1, 4.482 ms-1 for night, day and noon/evening time respectively
Lactones in butter, butteroil, and margarine (1975)

Abstract The γ‐ and Δ‐lactones of butter, butteroil, and margarine samples were determined by a recently developed extraction and chromatographic method. A chromatographic column is made of three layers consisting of 6 g aluminum oxide upon which is placed 35 g sodium sulfate and then a fat‐Celite mixture obtained by grinding 10 g sample with 35 g Celite 545. The column was eluted with acetonitrile, and the extract was concentrated and lactones determined by gas chromatography. γ‐Dodecalactone, Δ‐decalactone, Δ‐dodecalactone, and Δ‐tetradecalactone were recovered quantitatively. Freshly made butter had only 7 ppm of these lactones, whereas commercial samples ranged from 12–30 ppm. Two of eight commercial margarine samples had as much as 10 ppm of Δ‐decalactone and Δ‐dodecalactone. Comparison of unheated butteroil with butteroil heated at various temperatures showed a correlation of lactone content with time and temperature of heating. Butteroil heated at 65 or 100 C showed increasing levels of lactones up to 8 hr, whereas butteroil heated at 145 or 125 C showed a maximum production at ca. 2 and 4 hr, respectively.
Lactobacillus amylovorus, a New Starch-Hydrolyzing Species from Cattle Waste-Corn Fermentations (1981)

Several starch-hydrolyzing strains of Lactobacillus Beijerinck 1901 were isolated from cattle waste-corn fermentations. The isolates were facultatively anaerobic, gram-positive, nonmotile, nonsporeforming, rod-shaped organisms that grew singly and in short chains, produced lactic acid and small amounts of acetic acid but no gas from glucose, and did not exhibit oxidase-, catalase-, or nitrate-reducing activities. Growth occurred at 45°C but not at 15°C. dl-Lactic acid was synthesized from glucose. An extracellular amylolytic enzyme was formed. The organisms fermented amygdalin, cellobiose, esculin, fructose, galactose, glucose, maltose, mannose, salicin, starch, sucrose, and trehalose. Some strains fermented mannitol and lactose. Arabinose, gluconate, melezitose, melibiose, raffinose, rham-nose, ribose, and xylose were not fermented. The average guanine-plus-cytosine content of the deoxyribonucleic acid was 40.4 mol%. Reassociation values of 15% or less were obtained with the deoxyribonucleic acids of the starch hydrolyzers and those of the type strains of Lactobacillus acidophilus (Moro) Hansen and Mocquot 1970; Lactobacillus jensenii Gasser, Mandel, and Rogosa 1970; and Lactobacillus leichmanii (Henneberg) Bergey et al. 1923. The new species was differentiated from the three recognized species on the basis of starch fermentation, vitamin requirements, guanine-plus-cytosine contents, and stereoisomerism of lactic acid produced. It was concluded that these organisms represent strains of a hitherto unrecognized species for which the name Lactobacillus amylovorus is proposed. The type strain of L. amylovorus is NRRL B-4540.

Topically applied niacinamide in isoniazid-induced pellagra (1976)

• A patient with tuberculous meningitis developed a pellagra-like skin eruption after treatment with isoniazid. Administration of the drug was continued, and a topical preparation of niacinamide (nicotinamide) was applied to one half of the face and the back of one hand. The areas treated responded rapidly, and subsequently all affected areas of the patient were treated, with almost complete resolution of the rash. At the same time, there was noticeable improvement in the patient's depression and apathy. We suggest that all of these changes could be due to percutaneous absorption of niacinamide.

Sensitive plate assay for screening and detection of bacterial polyurethanase activity (2001)

These advantages are derived largely from the intense fluorescence observed due to the hydrolysis of substrate reacting with rhodamine B allowing for the use of low substrate concentrations and corresponding decrease in time required detecting low levels of enzyme activity.
Antimalarials. 11. 2-Vinylogs of substituted 2-aryl-4-quinoline amino alcohols (1976)

3-(P-Chlorobenzylidene)-5, 7-dimethyl-2, 3-dihydro-1H-cyclopenta[b]quinoline-9-(di-n-butylaminomethyl)methanol and 2-[beta-(p-chlorostyryl)]-6, 8-dimethylquinoline-4-(di-n-butylaminomethyl)methanol were synthesized from 6, -8-dimethyl-4-hydroxycarbostyril by 3, 3-dichlorination, dimethoxylation th the 3-ketal, basic hydrolysis to the glyoxal acetal, Pfitzinger condensation with cylopentanone or acetone to the 2, 3-trimethylene or 2-methylquinoline, condensation with p-ClPhCHO at the 2-methylene or 2-methyl group, hydrolysis to the 4-quinaldehyde, methylenation to the epoxide, and condensation with Bu2NH. Both were curative against P. berghei in mice. The first was the more effective: active at 10 mg/kg, completely curative at 40 mg/kg, and only mildly phototoxic in animals.

Fabrication and Cold Drawing of Copper Covetic Nanostructured Carbon Composites/ Otrzymywanie Oraz Ciągnienia Kompozytów Miedzianych Typu Covetic O Strukturze Nanometrycznej (2014)

Abstract This paper presents the research results of copper Covetic metallurgical synthesis along with the characterization of cast material and the processing of casts into wires. The Cu-C composite production method was based on patent applications of Third Millennium Metals. Obtained materials were tested for their chemical composition (including Secondary Ion Mass Spectrometry (SIMS) analysis for carbon presence), mechanical properties and electrical conductivity. Measurements were also performed for wires which were first cut from obtained casts and next cold drawn into final wire form. Produced wires were tested for their mechanical and electrical properties. Electrical conductivity of wires was measured with the use of high precision Thompson’s- Kelvin’s bridge type device. A key objective of the research was to determine if Covetic copper has higher electrical conductivity than pure oxygen free copper.
Morphological Stable Spirobifluorene/Oxadiazole Hybrids as Bipolar Host Materials for Efficient Green and Red Electrophosphorescence (2010)

A series of 9,9'-spirobifluorene/oxadiazole hybrids with various linkages between two components, namely SBF-p-OXD (1), SBF-m-OXD (2), and SBF-o-OXD (3) are designed and synthesized through Suzuki cross-coupling reactions. The incorporation of a rigid and bulky spirobifluorene moiety greatly improves their thermal and morphological stability, with T(d) (decomposition temperature) and T(g) (glass transition temperature) in the ranges of 401-480 degrees C and 136-210 degrees C, respectively. 2 and 3 with meta- and ortho-linkage display higher triplet energy and blue-shifted absorption and emission than their para-linked analogue 1 owing to the decreasing pi-conjugation between the two components. Their HOMO and LUMO energy levels depend on the linkage modes within the range of 5.57-5.64 eV and 2.33-2.49 eV, respectively. Multilayer deep red electrophosphorescent devices with 1-3 as hosts were fabricated and their EL efficiencies follow the order of 3 (o)>2 (m)>1 (p), which correlates with their triplet energy and the separation of HOMO and LUMO distributions at molecular orbitals. The maximum external quantum efficiencies of 11.7% for green and 9.8% for deep red phosphorescent organic light-emitting diodes (OLEDs) are achieved by using 2 and 3 as host materials, respectively.
Colonization of C57BL/6J and BALB/c Wild-Type and Knockout Mice with<i>Helicobacter pylori</i>: Effect of Vaccination and Implications for Innate and Acquired Immunity (2003)

The gram-negative bacterial pathogen Helicobacter pylori is a major cause of peptic ulcer disease and a risk factor for gastric cancer in humans. Adapted H. pylori strains, such as strain SS1, are able to infect mice and are a useful model for gastric colonization and vaccination studies. In this study we used a streptomycin-resistant derivative of H. pylori SS1 to analyze the colonization behavior and the success of vaccination in wild-type (wt) and various knockout mice of the BALB/c and C57BL/6J genetic backgrounds. We here report that BALB/c interleukin-4 knockout (IL-4(-/-)) mice are weakly overcolonized compared to the wt strain but that the IL-12(-/-) knockout results in a strong overcolonization (500%). Unexpectedly, in the C57BL/6J background the same knockouts behaved in diametrically opposed manners. The IL-4(-/-) mutation caused a 50% reduction and the IL-12(-/-) knockout caused a 95% reduction compared to the wt colonization rate. For C57BL/6J mice we further analyzed the IL-18(-/-) and Toll-like receptor 2 knockout mutations, which showed reductions to 66 and 57%, respectively, whereas mice with the IL-10(-/-) phenotype were hardly infected at all (5%). In contrast, the tumor necrosis factor receptor knockout (p55(-/-) and p55/75(-/-)) mice showed an overcolonization compared to the C57BL/6J wt strain. With exception of the low-level infected C57BL/6J IL-10(-/-) and IL-12(-/-) knockout mice, all knockout mutants were accessible to a prophylactic vaccination and their vaccination behavior was comparable to that of the wt strains.
Fluorinated Raspberry-like Polymer Particles for Superamphiphobic Coatings (2014)

Raspberry-like (RB) polymer particles were prepared, fluorinated, and cast onto glass plates to yield highly water- and oil-repellant superamphiphobic particulate coatings. To procure the RB particles, glycidyl-bearing 212 and 332 nm particles (abbreviated as s-GMA and l-GMA, respectively) were first prepared via surfactant-free free radical emulsion polymerization. Reacting the glycidyl groups of the l-GMA particles with 2,2'-(ethylenedioxy)bis(ethylamine) (EDEA) produced large amine-functionalized particles (l-NH2). The l-NH2 particles were then reacted with an excess of the s-GMA particles to create RB particles. For surface fluorination, the residual glycidyl groups of the smaller s-GMA particles surrounding the central l-NH2 core of the RB particles were first converted to amino groups by reaction with EDEA. The purified amino-bearing particles were subsequently reacted with an excess of a statistical copolymer poly(2-(perfluorooctyl)ethyl methacrylate-co-glycidyl methacrylate), P(FOEMA-co-GMA). Casting these particles onto glass plates yielded particulate films that exhibited static contact angles of 165 ± 2°, 155 ± 3°, 152 ± 4°, and 143 ± 1° and droplet rolling angles of <1 °, <1 °, 7 ± 2°, and 13 ± 2° for water, diiodomethane, corn-based cooking oil, and hexadecane droplets, respectively. These results demonstrated that this practical bottom-up approach could be used to produce superamphiphobic coatings.
Expression of the Minor Isoform Pea Ferredoxin in Tobacco Alters Photosynthetic Electron Partitioning and Enhances Cyclic Electron Flow  (2012)

Ferredoxins (Fds) are ferrosulfoproteins that function as low-potential electron carriers in plants. The Fd family is composed of several isoforms that share high sequence homology but differ in functional characteristics. In leaves, at least two isoforms conduct linear and cyclic photosynthetic electron transport around photosystem I, and mounting evidence suggests the existence of at least partial division of duties between these isoforms. To evaluate the contribution of different kinds of Fds to the control of electron fluxes along the photosynthetic electron transport chain, we overexpressed a minor pea (Pisum sativum) Fd isoform (PsFd1) in tobacco (Nicotiana tabacum) plants. The transplastomic OeFd1 plants exhibited variegated leaves and retarded growth and developmental rates. Photosynthetic studies of these plants indicated a reduction in carbon dioxide assimilation rates, photosystem II photochemistry, and linear electron flow. However, the plants showed an increase in nonphotochemical quenching, better control of excitation pressure at photosystem II, and no evidence of photoinhibition, implying a better dynamic regulation to remove excess energy from the photosynthetic electron transport chain. Finally, analysis of P700 redox status during illumination confirmed that the minor pea Fd isoform promotes enhanced cyclic flow around photosystem I. The two novel features of this work are: (1) that Fd levels achieved in transplastomic plants promote an alternative electron partitioning even under greenhouse light growth conditions, a situation that is exacerbated at higher light intensity measurements; and (2) that an alternative, minor Fd isoform has been overexpressed in plants, giving new evidence of labor division among Fd isoforms.
On-The-Fly Location Referencing Methods for Establishing Traffic Information Services (2007)

The paper presents different use cases for location referencing. It shows how a full service chain for traffic information services could be established and gave an overview of the widely used method traffic message channel (TMC). After a discussion about the growing requirements of telematics systems, a new approach to location referencing is presented: the on-the-fly methods. The difficulties regarding the development of on-the-fly methods was discussed and present the AGORA-C method which is currently in the standardisation process. An overview of the publicised test results using the AGORA-C method concerning its reliability and applicability was given. In addition, another algorithm for location referencing, MEI-LIN, was presented which focuses on a better identification of a location using topological information of the surrounding road network. An outlook on the current research in Europe shows the main future tasks of establishing location referencing methods
An Interoperable Authentication System using ZigBee-enabled Tiny Portable Device and PKI (2005)

Conventional authentication systems especially in a ubiquitous environment do not consider interoperability among different organizations. Therefore, carrying multiple security cards is inevitable for incompatible authentications. In this paper we propose a flexible, scalable, interoperable and usable authentication system using a ZigBee-enabled tiny portable device. It is specialized for the ubiquitous computing environments. In our authentication system, public key infrastructure (PKI) is used for interoperability and scalability. The noble security mechanism using PKI is also proposed. By applying Single Sign-On concept into our authentication system, possible frequent authentic operations in ubiquitous environment can be reduced. Instead of using the conventional security card, we developed a new lowpower tiny terminal which has ability of encryption-related computation. Therefore, authentication operations over many different services are possible with our tiny terminal. We presented three reference application models that use our authentication system in order to show that our proposed system does not sacrifice usability for security.
Production of Skatole and <i>para</i> -Cresol by a Rumen <i>Lactobacillus</i> sp (1981)

The objective of this study was to examine the substrate specificity of several ruminal strains of a Lactobacillus sp. which previously was shown to produce skatole (3-methylindole) by the decarboxylation of indoleacetic acid. A total of 13 compounds were tested for decarboxylase activity. The Lactobacillus strains produced p-cresol (4-methylphenol) by the decarboxylation of p-hydroxyphenylacetic acid, but did not produce either o-cresol or m-cresol from the corresponding hydroxyphenylacetic acid isomers. These strains also decarboxylated 5-hydroxyindoleacetic acid to 5-hydroxyskatole and 3,4-dihydroxyphenylacetic acid to methylcatechol. Skatole and p-cresol were produced in a 0.5:1 ratio, when indoleacetic acid and p-hydroxyphenylacetic acid were combined in equimolar concentrations. Competition studies with indoleacetic acid and p-hydroxyphenylacetic acid suggested that two different decarboxylating enzymes are involved in the production of skatole and p-cresol by these strains. This is the first demonstration of both skatole production and p-cresol production by a single bacterium.
Transformer-Isolated Resonant Driver for Parallel Strings With Robust Balancing and Stabilization of Individual LED Current (2013)

This paper presents a transformer-isolated resonant driver for parallel strings with robust balancing and stabilization of an individual LED current. The methodology is based on connecting multiple transformers in a daisy chain to balance the string currents and using them to form part of the resonant tank in a series-resonant converter. The input source and output strings are electrically isolated by transformers. Such structure behaves like a constant current source with multiple outputs for multiple LED strings. The string currents are found to be insensitive to the string voltages. In order to ensure service continuity of LEDs, each LED in a string has a bypass thyristor, which is triggered upon an open-circuit failure, so that the rest of the healthy LEDs in the string would still be operated. A 21 W prototype with seven strings has been built. Each string consists of three 1-W LEDs connected in series. Experimental results show that the LED current can still be regulated at the reference value within ±1% error even if the whole lamp has only one piece of LED in operation and the rest of LEDs fail short or open. Modeling, analysis, and design of the proposed driver will be given.
