Three-dimensional regularized focusing inversion of gravity gradient tensor component data (2004)

Abstract We develop a new method for interpretation of tensor gravity field component data, based on regularized focusing inversion. The focusing inversion makes its possible to reconstruct a sharper image of the geological target than conventional maximum smoothness inversion. This new technique can be efficiently applied for the interpretation of gravity gradiometer data, which are sensitive to local density anomalies. The numerical modeling and inversion results show that the resolution of the gravity method can be improved significantly if we use tensor gravity data for interpretation. We also apply our method for inversion of the gradient gravity data collected by BHP Billiton over the Cannington Ag-Pb-Zn orebody in Queensland, Australia. The comparison with the drilling results demonstrates a remarkable correlation between the density anomaly reconstructed by the gravity gradient data and the true structure of the orebody. This result indicates that the emerging new geophysical technology of the airborne gravity gradient observations can improve significantly the practical effectiveness of the gravity method in mineral exploration.
alpha-Adrenergic regulation of enzymes of amino acid metabolism in primary cultures of adult rat hepatocytes. (1983)

In primary cultures of rat hepatocytes, addition of dexamethasone (10 microM) plus glucagon (0.5 microM) caused several-fold increases in the activities of serine dehydratase (EC 4.2.1.13), tryptophan oxygenase (EC 1.13.11.11), and tyrosine aminotransferase (EC 2.6.1.5) in 24 h. These inductions were inhibited by insulin. Addition of epinephrine or phenylephrine at 10 microM blocked these inductions. This suppressive effect of adrenergic compounds was completely abolished by the alpha-adrenergic antagonist phenoxybenzamine at 10 microM. Immunochemical analysis with antiserum to serine dehydratase showed that the changes in enzyme activity were due to changes in the amount of enzyme. Epinephrine was effective even when glucagon was replaced by dibutyryl cAMP (50 microM), indicating that alpha-adrenergic suppression of enzyme inductions was mediated by a cAMP-independent mechanism. Furthermore, the findings that prazosin antagonized this epinephrine effect, but yohimbine did not, indicate that the alpha 1- but not the alpha 2-receptor is involved in this inhibition. However, the alpha-adrenergic effect was different from that of insulin in that, unlike the latter, the inductions of tryptophan oxygenase and tyrosine amino-transferase by dexamethasone alone were not inhibited. The alpha-adrenergic action apparently counteracts the action of glucagon and cAMP. For determination of the beta-adrenergic effect of catecholamines on the inductions of enzymes, beta-adrenergic compounds were tested without glucagon. Isoproterenol or epinephrine plus phenoxybenzamine induced tryptophan oxygenase and tyrosine aminotransferase. Induction of serine dehydratase was shown by isoproterenol only in the presence of 1-methyl-3-isobutylxanthine, an inhibitor of phosphodiesterase. These results indicate that catecholamines play dual roles in regulation of the amount of enzyme through their alpha 1- and beta-adrenergic actions.
Synthesis of <sup>123</sup>I‐labelled 4‐iodo‐2, 5‐dimethoxyphenylisopropylamine (1978)

Abstract A rapid and convenient synthesis of the psychotomimetic agent 4‐iodo‐2, 5‐dimethoxyphenylisopropylamine is described, incorporating the radioisotope 123 I (T 1/2 13 hr). With the amine function of 2, 5‐dimethoxyphenylisopropylamine blocked as the phthalimide, it was found that the aromatic 4‐position could be directly iodinated with iodine monochloride. The phthalic acid moiety was rapidly removed with hydrazine in butanol to provide the title compound, as the hydrochloride salt, in an overall yield of 10% and in a reaction time of less than one half‐life.

Global attracting set of a class of neutral hopfield neural networks (2003)

In the paper, we discuss the neutral Hopfield neural networks model. By using the spectral properties of matrix and differential inequality technique we derive the criteria of invariant set and global attracting set. Especially, we also give the sufficient condition for global stability when the system has an equilibrium point.
Preparation of alkyl tellurides and their reactions with carbon monoxide. (1987)

ベンゼンテルロレートイオンのアクリル酸エチル,メタクリル酸エチル,アクリロニトリル,メタクツロニトリルへのMichael型付加反応により対応するアルキルフェニルテルリドが合成されることを初めて明らかにした。また,他の新規ならびに既知の方法でいくっかの新しい有機テルリドを合成した。これらの有機デルリドをLi2PdCl4またはPd(OAc)2の存在下,1～20atmの一酸化炭素(CO)と反応させるとカルボン酸とオレフィンが生成し,CO挿入はフェニル炭素側に優先して起こるが,アルキル炭素側にも起こり最高22%の収率で脂肪族カルボン酸が生成することを明らかにした。反応は以下に示す段階を経て進むものと推定した。1)有機テルリドーパラジウム(II)塩錯体の形成,2)テルル上からパラジウム上への有機基の転移(トランスメタル化)によるアリールならびにアルキルパラジウム錯体の生成,3)COの挿入によるアシルパラジウム錯体の形成とその加水分解(カルボン酸生成)ならびにアルキルパラジウム錯体でのβ-脱離(オレフィン生成)。
Enhancing AODV performance by improved link metrics (2010)

AODV uses the minimum hop count as the connection metric do decide which route out of a set of possible routes should be selected to send a packet from a source to a destination. This metric can however be misleading if a route with a small number of hop counts is congested and interfered by neighbouring stations so that in this case another route could be faster despite of a higher hop count which would mean a worse route in the scope of legacy AODV. This paper investigates the enhancement of the AODV metric by three additional values which take the load and quality of the links along a routing path into account: the signal-to-noise ratio, the number of active neighbours and the queue filling state of individual nodes. Simulation results show that a significant enhancement of the throughput and the delay can be achieved in this way in comparison to legacy AODV. However, the amount of enhancement which is achieved by the different alternative metrics depends on the particular scenario.
Random depthwise signed convolutional neural networks. (2018)

We propose a random convolutional neural network to generate a feature space in which we study image classification and retrieval performance. Put briefly we apply random convolutional blocks followed by global average pooling to generate a new feature, and we repeat this k times to produce a k-dimensional feature space. This can be interpreted as partitioning the space of image patches with random hyperplanes which we formalize as a random depthwise convolutional neural network. In the network's final layer we perform image classification and retrieval with the linear support vector machine and k-nearest neighbor classifiers and study other empirical properties. We show that the ratio of image pixel distribution similarity across classes to within classes is higher in our network's final layer compared to the input space. When we apply the linear support vector machine for image classification we see that the accuracy is higher than if we were to train just the final layer of VGG16, ResNet18, and DenseNet40 with random weights. In the same setting we compare it to an unsupervised feature learning method and find our accuracy to be comparable on CIFAR10 but higher on CIFAR100 and STL10. We see that the accuracy is not far behind that of trained networks, particularly in the top-k setting. For example the top-2 accuracy of our network is near 90% on both CIFAR10 and a 10-class mini ImageNet, and 85% on STL10. We find that k-nearest neighbor gives a comparable precision on the Corel Princeton Image Similarity Benchmark than if we were to use the final layer of trained networks. As with other networks we find that our network fails to a black box attack even though we lack a gradient and use the sign activation. We highlight sensitivity of our network to background as a potential pitfall and an advantage. Overall our work pushes the boundary of what can be achieved with random weights.
Effect of replacing fishmeal and oil with simple or complex mixtures of vegetable ingredients in diets fed to Nile tilapia (Oreochromis niloticus) (2006)

The effect of replacing fishmeal with simple or complex mixtures of plant proteins in tilapia diets was examined. Diet formulations were arranged in a 2 × 4 factorial design with two types of plant protein mixtures used to replace fishmeal (simple: soybean meal and maize gluten meal or complex: soybean meal, maize gluten meal, dehulled flax, pea protein concentrate and canola protein concentrate) and four levels of protein originating from fishmeal (1000 g kg−1, 670 g kg−1, 330 g kg−1 and 0 g kg−1). Diets contained equal digestible protein (380 g kg−1) and digestible energy (17.6 MJ kg−1). The average daily gains, specific growth rates and feed efficiencies of fish fed diets with 0 g kg−1 fishmeal were significantly lower than fish fed diets with the 330 g kg−1, 670 g kg−1 or 1000 g kg−1 fishmeal levels. Fish fed the complex diets had significantly higher average daily gains, specific growth rates, feed : gain ratios and protein efficiency ratios than those fed the simple diets. Intestinal villus length decreased with decreasing levels of fishmeal and increased with increased diet complexity but the effects were not significant. Replacement of fishmeal with a complex mixture of plant ingredients may allow a greater replacement of fishmeal in diets fed to Nile tilapia.
Self directed unmanned aerial vehicle for target geo-localization system (2012)

An unmanned aerial vehicle which is capable of navigating autonomously to geo-localize arbitrary ground target is proposed here. From the video captured by the aerial vehicle, successive frame comparisons are done to extract 3D scene points. We have also designed certain decision making rules which is used for autonomous navigation. While traversing, target geo-localization system uses a camera placed at nadir point in order to find target's ground coordinates. This task can be achieved by first registering the video sequence obtained from the vehicle with aerial images of the region where the vehicle is flying. Then immediately perform geometric coordinate transformation from aerial images to video sequence frames. By using the video sequence captured by the vehicle, both autonomous navigation and coordinates of arbitrary ground target can be calculated. The major application of proposed work is search and rescue operations.
A transformation based algorithm for reversible logic synthesis (2003)

A digital combinational logic circuit is reversible if it maps each input pattern to a unique output pattern. Such circuits are of interest in quantum computing, optical computing, nanotechnology and low-power CMOS design. Synthesis approaches are not well developed for reversible circuits even for small numbers of inputs and outputs.In this paper, a transformation based algorithm for the synthesis of such a reversible circuit in terms of n × n Toffoli gates is presented. Initially, a circuit is constructed by a single pass through the specification with minimal look-ahead and no back-tracking. Reduction rules are then applied by simple template matching. The method produces near-optimal results for 3-input circuits and also produces very good results for larger problems.
Characterizing Oligosaccharides Using Injected-Ion Mobility/Mass Spectrometry (1997)

Injected-ion mobility/mass spectrometry techniques have been used to measure the reduced ion mobilities for negatively charged raffinose, melezitose and α-, β-, and γ-cyclodextrins formed by electrospray ionization. At low injection energies, the mass spectra are dominated by negatively charged (deprotonated) parent ions. At high injection energies, the mass spectra recorded for the cyclodextrins and raffinose display peaks that result from cross-ring cleavage of individual sugar units. Melezitose dissociates by cleavage of the glycosidic bonds. The ion mobility distributions can be used to distinguish between different isomeric forms of parent and fragment ions having the same mass-to-charge ratios.
Varying Cost and Free Nicotinic Acid Content in Over-the-Counter Niacin Preparations for Dyslipidemia (2003)

No-flush preparations of over-the-counter niacin contain no free nicotinic acid and should not be used to treat dyslipidemia. Over-the-counter sustained-release niacin contains free nicotinic acid, but some brands are hepatotoxic. Immediate-release niacin contains free nicotinic acid and is the least expensive form of over-the-counter niacin.
Effective Dielectric Constant Method for a Planar Helix With Straight-Edge Connections (2009)

A new planar slow-wave structure consisting of a planar helix with straight-edge connections is presented. It is shown that the phase velocity of the proposed structure can be much slower than that for a rectangular helix with identical cross-sectional dimensions. Further, the dispersion characteristics are obtained simply by using the effective dielectric constant method; it is shown that the method yields results which, far-from-cutoff, match very well with simulation results obtained from CST Microwave Studio. The proposed structure has the potential of easier fabrication using microfabrication techniques.
Specific quantification of human genomes from low copy number DNA samples in forensic and ancient DNA studies. (2003)

We reviewed the current methodologies used for human DNA quantitation in forensic and ancient DNA studies, including sensitive hybridization methods based on the detection of nuclear alpha-satellite repetitive DNA regions or more recently developed fluorogenic real-time polymerase chain reaction (PCR) designs for the detection of both nuclear and mitochondrial DNA regions. Special emphasis has been put on the applicability of recently described different real-time PCR designs targeting different fragments of the HV1 mtDNA control region, and a segment of the X-Y homologous amelogenin gene. The importance of these quantitative assays is to ensure the consistency of low copy number DNA typing (STR profiling and mtDNA sequencing).
Reconstitution of an apicoplast‐localised electron transfer pathway involved in the isoprenoid biosynthesis of <i>Plasmodium falciparum</i> (2005)

In the malaria parasite Plasmodium falciparum isoprenoid precursors are synthesised inside a plastid-like organelle (apicoplast) by the mevalonate independent 1-deoxy-d-xylulose-5-phosphate (DOXP) pathway. The last reaction step of the DOXP pathway is catalysed by the LytB enzyme which contains a [4Fe-4S] cluster. In this study, LytB of P. falciparum was shown to be catalytically active in the presence of an NADPH dependent electron transfer system comprising ferredoxin and ferredoxin-NADP(+) reductase. LytB and ferredoxin were found to form a stable protein complex. These data suggest that the ferredoxin/ferredoxin-NADP(+) reductase redox system serves as the physiological electron donor for LytB in the apicoplast of P. falciparum.
Surface Functionalization of Zinc Oxide Nanoparticles: An Investigation in the Aerosol State (2011)

The interactions of the simple amine functional groups with the surfaces of ZnO aerosol nanoparticles have been investigated. The ZnO particles were synthesized from the metal–organic precursor methylzinc isopropoxide {[CH3ZnOCH(CH3)2]4, MZI}. Solid MZI was evaporated at 85–120 °C, and then swept by an inert carrier gas at atmospheric pressure through a tube furnace operating at 300–900 °C. Thermal decomposition of MZI led to the formation of stoichiometric ZnO nanoparticles of mobility diameter 3–50 nm. The size, structure, and composition of synthesized particles were characterized by differential mobility analysis (DMA), X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform IR spectroscopy (FTIR). The aerosolized ZnO nanoparticles were reacted with two gas-phase organic species: 1-butylamine and 1-hexylamine. Uptake was monitored by tandem differential mobility analysis (T-DMA). These results represent the first work on surface functionalization of ZnO nanoparticles in the aerosol state. They establish a new approach for manipulating quantum dot materials in the aerosol state.
Systolic Blood Pressure Response to Exercise Stress Test and Risk of Stroke (2001)

SBP rise during exercise and percent maximum SBP at 2 minutes after exercise were directly and independently associated with the risk of all stroke and ischemic stroke. Exercise SBP testing may be recommended as an additional tool in the prediction of future stroke.

Self-Organized Beam Scheduling as an Enabler for Coexistence in 5G Unlicensed Bands (2017)

In order to support user data rates of Gbps and above in the fifth generation (5G) communication systems, millimeter wave (mm-wave) communication is proposed as one of the most important enabling technologies. In this paper, we consider the spectrum bands shared by 5G cellular base stations (BS) and some existing networks, such as WiGig and proposed a method for spectrally efficient coexistence of multiple interfering BSs through adaptive self-organized beam scheduling. These BSs might use multiple radio access technologies belonging to multiple operators and are deployed in the unlicensed bands, such as 60GHz. Different from the recently emerging coexistence scenarios in the unlicensed 5GHz band, where the proposed methods are based on omni-directional transmission, beamforming needs to be employed in mm-wave bands to combat the high path loss problem. The proposed method is concerned with this new scenario of communication in the unlicensed bands where (a) beam-forming is mandatory to combat severe path loss, (b) without optimal scheduling of beams mutual interference could be severe due to the possibility of beam-collisions, (c) unlike LTE which users time-frequency resource blocks, a new resource, i.e., the beam direction, is used as mandatory feature. We propose in this paper a novel multi-RAT coexistence mechanism where neighbouring 5G BSs, each serving their own associated users, schedule their beam configurations in a self-organized manner such that their own utility function, e.g. spectral efficiency, is maximized. The problem is formulated as a combinatorial optimization problem and it is shown via simulations that our proposed distributed algorithms yield a comparable spectral efficiency for the entire networks as that using an exhaustive search, which requires global coordination among coexisting RATs and also has a much higher algorithmic complexity.
Psychomotor effects of ketorolac in comparison with buprenorphine and diclofenac [see comments] (1989)

1. Ketorolac is an investigational non-opioid analgesic. Buprenorphine, an opioid compound and diclofenac, a non-steroidal anti-inflammatory, are analgesics used in clinical practise. 2. The psychomotor effects of ketorolac (30 mg), buprenorphine (0.3 mg), diclofenac (50 mg) and placebo all administered i.m., were examined in 12 healthy male volunteers (age 19-38 years), up to 8 h post-dose. 3. Creatine phosphokinase (CPK) was measured up to 24 h post-dose, providing an indication of local tissue damage following injection. 4. Buprenorphine caused significant psychomotor impairment in seven out of eight psychomotor tests. The effects consistently peaked 4 h post-dose and were still apparent in many cases 8 h post-dose. These psychomotor effects were supported by marked symptoms in all volunteers. 5. Ketorolac and diclofenac had no clinically significant effects on psychomotor tests and only minimal symptoms were reported. 6. Diclofenac caused a marked increased in CPK (mean Cmax 298 iu l-1) compared with ketorolac (mean Cmax 70 iu l-1) and buprenorphine (mean Cmax 68 iu l-1). 7. These results suggest that ketorolac and diclofenac are suitable for administration following day case surgery.

DIMENSIONS: Why do we need a new Data Handling architecture for Sensor Networks? (2002)

An important class of networked systems is emerging that involve very large numbers of small, low-power, wireless devices. These systems offer the ability to sense the environment densely, offering unprecedented opportunities for many scientific disciplines to observe the physical world. In this paper, we argue that a data handling architecture for these devices should incorporate their extreme resource constraints- energy, storage and processing- and spatio-temporal interpretation of the physical world in the design, cost model, and metrics of evaluation. We describe DIMENSIONS, a system that provides a unified view of data handling in sensor networks, incorporating long-term storage, multi-resolution data access and spatio-temporal pattern mining. 1.
