Study on Energy Dissipation of Viscous Damper for Long-Span Suspension Bridges (2019)

Viscous dampers are important devices to dissipate the vibration energy of long-span bridges. In the paper, nonlinear time history analysis was used to study the effects of this type of dam-per on suspension bridges. The influence of nonlinear viscous dampers on the seismic response of long-span suspension bridges was analyzed, which was based on a real project. The quantitative relationship between the displacement of the bridge girder and the tower with the damping coefficient and velocity index was investigated. The results showed that the displacement of the bridge girder under earthquakes can be effectively reduced by selecting the appropriate damping coefficient and velocity index of the nonlinear viscous dampers, and the best energy dissipation and seismic reduction effect for long-span suspension bridges can be obtained.

Human and Machine Performance on Periocular Biometrics Under Near-Infrared Light and Visible Light (2011)

Periocular biometrics is the recognition of individuals based on the appearance of the region around the eye. Periocular recognition may be useful in applications where it is difficult to obtain a clear picture of an iris for iris biometrics, or a complete picture of a face for face biometrics. Previous periocular research has used either visible-light (VL) or near-infrared (NIR) light images, but no prior research has directly compared the two illuminations using images with similar resolution. We conducted an experiment in which volunteers were asked to compare pairs of periocular images. Some pairs showed images taken in VL, and some showed images taken in NIR light. Participants labeled each pair as belonging to the same person or to different people. Untrained participants with limited viewing times correctly classified VL image pairs with 88% accuracy, and NIR image pairs with 79% accuracy. For comparison, we presented pairs of iris images from the same subjects. In addition, we investigated differences between performance on light and dark eyes and relative helpfulness of various features in the periocular region under different illuminations. We calculated performance of three computer algorithms on the periocular images. Performance for humans and computers was similar.
A Quadrature Radar Topology With Tx Leakage Canceller for 24-GHz Radar Applications (2007)

A quadrature radar topology with a Tx leakage canceller is presented. The canceller is composed of four branch-line hybrid couplers, a 90deg delay line, and a Wilkinson combiner. It has high Tx-to-Rx isolation and wide bandwidth characteristics. The isolation is 35.27 dB at 24 GHz and does not drop below 30 dB over a 2-GHz bandwidth. Given that the isolation of the branch-line hybrid coupler is 21.5 dB, the enhancement of the isolation is expected to be 13.77 dB. A quadrature Doppler radar front-end with the canceller was implemented. The noise level in the mixer output is lower by 9 dB compared with that of a conventional quadrature radar. This radar can measure speed as low as 0.76 mm/s, which correspond to a 0.12-Hz Doppler shift. It is also able to detect signs of the Doppler shift from a moving target due to its quadrature topology.
Vitamin C and elemental composition of some bushfruits (1990)

Abstract Vitamin C and elemental analysis of a range of indigenous bushfruit from the Northern Territory, Darwin, Australia, was carried out. The results suggest that bushfruit may be a valuable food resource. In the majority of cases, vitamin C and elemental composition of bushfruits were comparable to those of western fruits in the same fruit category. Billy goat plums (Terminalia fertinandiana) have the highest vitamin C content, while K concentration is generally high as compared to other elements. Morinda citrifolia gave strong test for the presence of terpenes.
Pathology of the optic nerve in experimental acute glaucoma. Electron microscopic studies. (1968)

The pathology of the optic nerve resulting from experimental acute glaucoma was studied by electron microscopy in owl monkeys (Aotus trivirgatus). Two distinct stages in the evolution of the pathological changes were recognized. The first stage consisted of widespread axonal changes with or without focal areas of necrosis. The axons showed severe hydropic swellings and/or reactive axonal enlargements filled with mitochondria, dense bodies, vesicles, and membranous whorls. The hydropic degeneration of the axons accounted for the vacuolar changes seen by light microscopy in severely affected nerves. No enlargement of extracellular spaces and no penetration of vitreous could be demonstrated at this stage. The second phase, developing several days after onset of glaucoma, began with the cystic transformation of necrotic tissue beneath the internal limiting membrane, causing its dissolution or rupture in focal areas. Vitreous, together with injected electron-dense markers (Thorotrast or India ink), was forced through these gaps into the damaged nerve, producing cavernous extracellular spaces. The degenerated axons and other debris were removed by phagocytes. The origin of at least some of these cells from hematogenous monocytes is discussed and illustrated.
Data Mining for Fun and Profit (2000)

Data mining is defined as the process of seeking interesting or valuable information within large data sets. This presents novel challenges and problems, distinct from those typically arising in the allied areas of statistics, machine learning, pattern recognition or database science. A distinction is drawn between the two data mining activities of model building and pattern detection. Even though statisticians are familiar with the former, the large data sets involved in data mining mean that novel problems do arise. The second of the activities, pattern detection, presents entirely new classes of challenges, some arising, again, as a consequence of the large sizes of the data sets. Data quality is a particularly troublesome issue in data mining applications, and this is examined. The discussion is illustrated with a variety of real examples.
Recent Developments and Future Challenges in Medical Mixed Reality (2017)

Mixed Reality (MR) is of increasing interest within technology-driven modern medicine but is not yet used in everyday practice. This situation is changing rapidly, however, and this paper explores the emergence of MR technology and the importance of its utility within medical applications. A classification of medical MR has been obtained by applying an unbiased text mining method to a database of 1,403 relevant research papers published over the last two decades. The classification results reveal a taxonomy for the development of medical MR research during this period as well as suggesting future trends. We then use the classification to analyse the technology and applications developed in the last five years. Our objective is to aid researchers to focus on the areas where technology advancements in medical MR are most needed, as well as providing medical practitioners with a useful source of reference.

Combining up to eight telescope beams in a single chip (2000)

In this paper we show that integrated optics offer a very simple and low cost way to combine up to eight beams of an interferometric optical array. These beam combiners will allow accurate visibilities and phase closure terms measurements, and provide consequently, high quality information for astronomical image reconstruction. We present optical designs for two different chips. Using previous laboratory experiments we extrapolate the performances, constraints and limits of different beam combination concepts. In particular spatial encoding and temporal encoding of `all-in-one' schemes are compared and their main properties are evaluated.
Modulation of Phosphoenolpyruvate Synthase Expression Increases Shikimate Pathway Product Yields in <i>E. coli</i> (2002)

Product yields in microbial synthesis are ultimately limited by the mechanism utilized for glucose transport. Altered expression of phosphoenolpyruvate synthase was examined as a method for circumventing these limits. Escherichia coli KL3/pJY1.216A was cultured under fed-batch fermentor conditions where glucose was the only source of carbon for the formation of microbial biomass and the synthesis of product 3-dehydroshikimic acid. Shikimate pathway byproducts 3-deoxy-D-arabino-heptulosonic acid, 3-dehydroquinic acid, and gallic acid were also generated. An optimal expression level of phosphoenolpyruvate synthase was identified, which did not correspond to the highest expression levels of this enzyme, where the total yield of 3-dehydroshikimic acid and shikimate pathway byproducts synthesized from glucose was 51% (mol/mol). For comparison, the theoretical maximum yield is 43% (mol/mol) for synthesis of 3-dehydroshikimic acid and shikimate pathway byproducts from glucose in lieu of amplified expression of phosphoenolpyruvate synthase.
Performance analysis of mesh interconnection networks with deterministic routing (1994)

This paper develops detailed analytical performance models for k-ary n-cube networks with single-hit or infinite buffers, wormhole routing, and the nonadaptive deadlock-free routing scheme proposed by Dally and Seitz (1987). In contrast to previous performance studies of such networks, the system is modeled as a closed queueing network that: includes the effects of blocking and pipelining of messages in the network; allows for arbitrary source-destination probability distributions; and explicitly models the virtual channels used in the deadlock-free routing algorithm. The models are used to examine several performance issues for 2-D networks with shared-memory traffic. These results should prove useful for engineering high-performance systems based on low-dimensional k-ary n-cube networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<i>Trypanosoma brucei</i> CTP synthetase: A target for the treatment of African sleeping sickness (2001)

The drugs in clinical use against African sleeping sickness are toxic, costly, or inefficient. We show that Trypanosoma brucei, which causes this disease, has very low levels of CTP, which are due to a limited capacity for de novo synthesis and the lack of salvage pathways. The CTP synthetase inhibitors 6-diazo-5-oxo-l-norleucine (DON) and alpha-amino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid (acivicin) reduced the parasite CTP levels even further and inhibited trypanosome proliferation in vitro and in T. brucei-infected mice. In mammalian cells, DON mainly inhibits de novo purine biosynthesis, a pathway lacking in trypanosomes. We could rescue DON-treated human and mouse fibroblasts by the addition of the purine base hypoxanthine to the growth medium. For treatment of sleeping sickness, we propose the use of CTP synthetase inhibitors alone or in combination with appropriate nucleosides or bases.
Wiener filter realization for target detection using group delay statistics (1993)

Several techniques are demonstrated for Wiener filter realization based on group delay statistics. The theoretical analysis shows that an inverse relationship exists between the frequency-domain signal-to-noise ratio and the group delay moving standard deviation and/or group delay moving entropy. Therefore, an adaptive Wiener filter can be realized without a priori knowledge of the signal and noise spectra. Group delay statistics estimation algorithms are proposed and evaluated by simulation. Experimental data from ultrasonic flaw detection are presented to support the effectiveness of the techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

LIDAR pulse coding for high resolution range imaging at improved refresh rate (2016)

In this study, a light detection and ranging system (LIDAR) was designed that codes pixel location information in its laser pulses using the direct- sequence optical code division multiple access (DS-OCDMA) method in conjunction with a scanning-based microelectromechanical system (MEMS) mirror. This LIDAR can constantly measure the distance without idle listening time for the return of reflected waves because its laser pulses include pixel location information encoded by applying the DS-OCDMA. Therefore, this emits in each bearing direction without waiting for the reflected wave to return. The MEMS mirror is used to deflect and steer the coded laser pulses in the desired bearing direction. The receiver digitizes the received reflected pulses using a low-temperature-grown (LTG) indium gallium arsenide (InGaAs) based photoconductive antenna (PCA) and the time-to-digital converter (TDC) and demodulates them using the DS-OCDMA. When all of the reflected waves corresponding to the pixels forming a range image are received, the proposed LIDAR generates a point cloud based on the time-of-flight (ToF) of each reflected wave. The results of simulations performed on the proposed LIDAR are compared with simulations of existing LIDARs.
Substrate integrated waveguide (SIW) linear phase filter (2005)

A planar four-pole linear phase filter centered at 10GHz based on substrate integrated waveguide (SIW) is proposed. The filter is composed of four side-by-side horizontally oriented SIW cavities, which are coupled in turn by evanescent waveguide sections with three direct coupling and one cross coupling between the first and fourth SIW cavities. The SIW cavities are fed by microstrips through coupling slots. A curve-fitting technique is adopted to improve the efficiency of the design process. The measured results are presented and compared with the results simulated by a high-frequency structure simulator. Good agreement between the simulated and measured results is observed.
An Overview of Modelling in Agricultural Management (1972)

The effect of giving feeds containing soya-bean meal treated or extracted with ethanol on digestive processes in the prerurninant calf (1979)

1. Preruminant calves, fitted with abomasal and re-entrant ileal cannulas, were given, at intervals of 2–3 d by infusion into the absomasum, a series of five single experimental feeds containing heated soyabean flour (product B) as the only protein source. The calves were sensitized in this way to a constituent in the soya beans and by the fifth feed showed a number of digestive disturbances. Further test feeds were then given in which heated soya-bean flour was sometimes replaced by soya-bean products prepared under laboratory or commercial conditions by treating I part fat-free raw soya-bean meal with either I part (product M) or 4 parts (product L) ethanol (750 ml/l) at 78–80° and evaporating the whole mixture to dryness, or by extracting I part meal with 4 parts aqueous ethanol under similar conditions (product K). Products M, L and K were heated with steam and finely ground. Feeds prepared from casein and from commerical ethanol-extracted concentrate (product D) were also examined. 2. Measurements were made of transit time through the small intestine, flow rate of ileal digesta, recovery of polyethylene glycol (a water-soluble marker added to the feed) and net nitrogen absorption up to the distal ileum. Compared to feeds based on casein, feeds containing products K, L or M showed some differences in digesta movement and N uptake, but much less disturbance than feeds containing product B. Products prepared by extracting soya-bean meal with ethanol appeared to be slightly superior to those prepared from meal treated with ethanol, but the differences were not significant. 3. Weanling rats were used to assess the nutritive value of soya-bean products by an N balance method. Digestibilities (mean 0.948) and biological values (mean 0.860) obtained for products B, D, K and L did not differ significantly. 4. Results confirmed that extracting soya-bean meal with hot aqueous ethanol improved its value for calf feeding and indicated that at least part of the effect was due to the destruction of a toxic constituent present in the soya bean which probably acted by inducing a gastrointestinal allergy.
Ion Channels as Therapeutic Targets in High Grade Gliomas (2020)

Glioblastoma multiforme (GBM) is a lethal brain cancer with an average survival of 14-15 months even with exhaustive treatment. High grade gliomas (HGG) represent the leading cause of CNS cancer-related death in children and adults due to the aggressive nature of the tumour and limited treatment options. The scarcity of treatment available for GBM has opened the field to new modalities such as electrotherapy. Previous studies have identified the clinical benefit of electrotherapy in combination with chemotherapeutics, however the mechanistic action is unclear. Increasing evidence indicates that not only are ion channels key in regulating electrical signaling and membrane potential of excitable cells, they perform a crucial role in the development and neoplastic progression of brain tumours. Unlike other tissue types, neural tissue is intrinsically electrically active and reliant on ion channels and their function. Ion channels are essential in cell cycle control, invasion and migration of cancer cells and therefore present as valuable therapeutic targets. This review aims to discuss the role that ion channels hold in gliomagenesis and whether we can target and exploit these channels to provide new therapeutic targets and whether ion channels hold the mechanistic key to the newfound success of electrotherapies.
Macrocyclic Amphiphiles. 1. Properties of Calix[4]resorcinarene Derivatives Substituted with Azobenzenes in Solutions and Monolayers (1997)

Photochemical behavior of calix[4]resorcinarenes (CRAs) and O-octaacetylated derivatives having four azobenzene residues at their lower rim in solutions and monolayers is described. UV irradiation of an O-octaacetylated CRA in homogeneous solution gave rise to a photostationary state consisting of a possible six isomers as a result of normal photoisomerization. The compound exhibited reversible precipitation/dissolution cycles in a diluted methanol solution upon alternate irradiation with UV and visible light owing to its scarce solubility of all-trans isomer. Wherease azobenzene chromophores tethered from the cyclic skeleton displayed marked intermolecular interactions in monolayers on a water surface, trans-to-cis photoisomerization took place even in compressed monolayers. The level of the photoisomerizability was dependent on the chemical structure and surface pressures. Monolayers of azobenzene CRAs exhibited the reversible alteration of their areas under a constant surface pressure upon UV and visible light irradiation because of the drastic shape change of the chromophores.
