A Hybrid Transformer Topology for Distribution Network Voltage Regulation (2021)

Worldwide, distributed generation sources are being installed in increasing numbers within distribution networks. This poses new challenges for distribution network operators, including voltage fluctuations beyond permissible limits that can differ in different parts of the same distribution network. The Hybrid Transformer (HT) is an effective solution that can mitigate voltage fluctuations continuously, dynamically and in a local manner, through combining a standard distribution transformer with a power electronic converter. In this paper a retrofittable HT topology is proposed. It utilises a second, fractionally-rated line frequency transformer (LFT) to enable the use of low-voltage power electronics with low power ratings for reduced costs and complexity. The proposed topology is modelled and a scaled hardware prototype is used to verify theory and simulation results. The simulation and experimental results show the efficacy of the proposed topology, its applicability to mitigate voltage fluctuations, and its benefits over alternative approaches.
SPATIAL MODULATION OF LIGHT USING SURFACE WAVES IN AN INTERFEROMETER (1970)

An optical phase grating has been generated by introducing surface waves on one face of a Fabry-Perot interferometer. This device called SWIM (Surface Wave Interference Modulator) produces a diffraction pattern at the Fourier plane in which the light intensity of the first-order modulated beam is 1% of the zeroth order with an acoustic power of 0.85 mW/mm beam width. First-order intensities greater than 10% have been realized; however, the process is not linear at this modulation depth.
Increased levels of acidic free-N-glycans, including multi-antennary and fucosylated structures, in the urine of cancer patients (2022)

We recently reported increased levels of urinary free-glycans in some cancer patients. Here, we focused on cancer related alterations in the levels of high molecular weight free-glycans. The rationale for this study was that branching, elongation, fucosylation and sialylation, which lead to increases in the molecular weight of glycans, are known to be up-regulated in cancer. Urine samples from patients with gastric cancer, pancreatic cancer, cholangiocarcinoma and colorectal cancer and normal controls were analyzed. The extracted free-glycans were fluorescently labeled with 2-aminopyridine and analyzed by multi-step liquid chromatography. Comparison of the glycan profiles revealed increased levels of glycans in some cancer patients. Structural analysis of the glycans was carried out by performing chromatography and mass spectrometry together with enzymatic or chemical treatments. To compare glycan levels between samples with high sensitivity and selectivity, simultaneous measurements by reversed-phase liquid chromatography-selected ion monitoring of mass spectrometry were also performed. As a result, three lactose-core glycans and 78 free-N-glycans (one phosphorylated oligomannose-type, four sialylated hybrid-type and 73 bi-, tri- and tetra-antennary complex-type structures) were identified. Among them, glycans with α1,3-fucosylation ((+/- sialyl) Lewis X), triply α2,6-sialylated tri-antennary structures and/or a (Man3)GlcNAc1-core displayed elevated levels in cancer patients. However, simple α2,3-sialylation and α1,6-core-fucosylation did not appear to contribute to the observed increase in the level of glycans. Interestingly, one tri-antennary free-N-glycan that showed remarkable elevation in some cancer patients contained a unique Glcβ1-4GlcNAc-core instead of the common GlcNAc2-core at the reducing end. This study provides further insights into free-glycans as potential tumor markers and their processing pathways in cancer.
Epitaxial PLZT waveguide technologies for integrated photonics (2005)

In order to integrate various photonic functions and/or many channels into one chip, (Pb,La)(Zr,Ti)O<sub>3</sub> (PLZT) waveguide technologies have been developed. PLZT is one of the best candidates in terms of dense integration and device miniaturization due to its efficient voltage-induced index change and high refractive index. We have established a solid-phase epitaxy to grow low-loss PLZT thin film waveguides, since the formation of low optical propagation loss PLZT waveguides had been difficult with typical vapor phase growth techniques. PLZT waveguides with PLZT buffer layers are grown on Nb-doped semiconductive SrTiO<sub>3</sub> substrates for the effective overlap integral of the optical field and the electric field. Efficient control of light coupled in the waveguides is achieved by applying voltage between the top electrodes and the substrates to induce the excellent electro-optic properties of PLZT waveguides. In addition, optical switching devices, which are the key elements of various integrated devices, are fabricated in the PLZT waveguides, showing low-voltage drive and ultra-fast response characteristics. Further key developments such as matrix switches, switch-VOA arrays, and modulator arrays directed toward integrated photonics are also discussed.
Variation in Cadmium Accumulation Potential and Tissue Distribution of Cadmium in Tobacco (1986)

Variation in Cd accumulation between Nicotiana species but not varieties has been observed in seedlings grown in solution culture with moderate-to-low levels of Cd. Nicotiana tabacum has been characterized as a leaf and root accumulator while Nicotiana rustica is shown to be primarily a root accumulator, having about half the leaf Cd per gram dry weight of N. tabacum. This phenotype is retained in the mature N. rustica plant. To characterize these two species which differ in their modes of Cd accumulation, tissue Cd distribution, partitioning of metal in soluble and insoluble fractions and the contribution of soluble Cd-binding proteins (peptides) to total plant Cd was assessed using mature solution cultured plants. Metal accumulation was highest in the most mature leaves and in young roots. The preponderance of young roots in N. rustica may, in part, account for low leaf/high root Cd accumulation in this species. While Cd-binding peptides appear to be a principal form of Cd in leaves and roots of seedlings and these also occur in mature leaves, Cd is equally distributed between soluble (about 80% as Cd-binding peptide) and uncharacterized insoluble forms in mature plant roots.
Monolithically integrated optical interferometerfor refractometry (1997)

A monolithically integrated optical sensor chip for measurement of analyte refractive index changes has been demonstrated. The 5 × 0.15 mm2 GaAs/AlGaAs-based integrated optical circuit consists of a Mach-Zehnder interferometer with an integrated DBR laser, a waveguide detector and a dielectric waveguide sensor pad embedded in one interferometer arm.
The Design of a Two-wheeled Mobile Platform with Face Following Functionality (2018)

This study designs a two-wheeled mobile platform with autonomous movement and face following functionality. The autonomous movement mechanism uses the change of the center of gravity to make the two-wheeled mobile platform move forward or backward, and utilizes simultaneously the PID controller to keep its balance. The face following functionality uses a tablet with an image sensor and an image processing to perform face recognition, and finds a tracking direction. Experimental results show that the two-wheeled mobile platform can perform autonomous balance, the movement and face tracking functionality.
Integrated Data, Message, and Process Recovery for Failure Masking in Web Services (2005)

Modern Web Services applications encompass multiple distributed interacting components, possibly including millions of lines of code written in different programming languages. With this complexity, some bugs often remain undetected despite extensive testing procedures, and occasionally cause transient system failures. Incorrect failure handling in applications often leads to incomplete or to unintentional request executions. A family of recovery protocols called interaction contracts provides a generic solution to this problem by means of system-integrated data, process, and message recovery for multi-tier applications. It is able to mask failures, and allows programmers to concentrate on the application logic, thus speeding up the development process. This thesis consists of two major parts. The first part formally specifies the interaction contracts using the state-and-activity chart language. Moreover, it presents a formal specification of a concrete Web Service that makes use of interaction contracts, and contains no other error-handling actions. The formal specifications undergo verification where crucial safety and liveness properties expressed in temporal logics are mathematically proved by means of model checking. In particular, it is shown that each end-user request is executed exactly once. The second part of the thesis demonstrates the viability of the interaction framework in a real world system. More specifically, a cascadable Web Service platform, EOS, is built based on widely used components, Microsoft Internet Explorer and PHP application server, with interaction contracts integrated into them.
Water-Soluble Anthraquinone Photocatalysts Enable Methanol-Driven Enzymatic Halogenation and Hydroxylation Reactions (2020)

Peroxyzymes simply use H<sub>2</sub>O<sub>2</sub> as a cosubstrate to oxidize a broad range of inert C-H bonds. The lability of many peroxyzymes against H<sub>2</sub>O<sub>2</sub> can be addressed by a controlled supply of H<sub>2</sub>O<sub>2</sub>, ideally in situ. Here, we report a simple, robust, and water-soluble anthraquinone sulfonate (SAS) as a promising organophotocatalyst to drive both haloperoxidase-catalyzed halogenation and peroxygenase-catalyzed oxyfunctionalization reactions. Simple alcohols, methanol in particular, can be used both as a cosolvent and an electron donor for H<sub>2</sub>O<sub>2</sub> generation. Very promising turnover numbers for the biocatalysts of up to 318 000 have been achieved.
Reinforcement Learning-Based Energy-Efficient Data Access for Airborne Users in Civil Aircrafts-Enabled SAGIN (2021)

Airborne users are always dreaming of enjoying a good Internet access experience while in the air. However, due to long propagation delay and limited network coverage, the existing data communication methods utilized in space and ground communications not only fail to ensure the quality-of-service (QoS) of airborne users, but also incur significant energy consumption to process content requests. In this paper, we introduce the aeronautical ad hoc network (AANET) as a new method of network access and design an energy-efficient data access scheme in civil aircrafts-enabled space-air-ground integrated networks (CAE-SAGIN). In order to minimize the energy consumption, we propose a service selection scheme based on reinforcement learning and formulate a joint optimization problem of resource allocation and request distribution. Leveraged by the Lyapunov optimization method, the optimization problem can be solved by the proposed joint optimization algorithm. Extensive simulations are conducted to confirm the stability of the CAE-SAGIN, and demonstrate that the proposed data access scheme can effectively reduce both the energy consumption and the processing delay. Moreover, the advantages of using AANET are becoming more obvious when higher data rate is required.
Study of the Strain Rate Effect on Cold-Reduced Carbon Steel and Aluminium Alloy with Numerical Simulations (2006)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Ultrastructural changes in stored platelets. (1992)

A wide variety of lesions develop in blood platelets stored in vitro for long periods of time. Most of them reflect activation and damage caused by lack of gas exchange across the wall of the container and a fall in pH below 6. Newer bags facilitate O2/CO2 exchange and maintain a neutral pH. As a result, most of the lesions reflecting acidic damage or destruction have disappeared. Some storage lesions persist, however. Formation of platelets resembling doughnuts occurs in the first 24 or 48 hours after collection and concentration. They are infrequent in currently used bags. Giant alpha granules resulting from fusion of normal-sized organelles, however, are not rare. They appear as early as 4 to 5 days, even under the best conditions, and increase in frequency up to 14 days. The basis for their development remains obscure.
Thoracic fluid detection and monitoring system using metamaterial loaded Yagi-antenna array (2016)

The possibility of building a full clinical-system for thoracic fluid detection inside the human torso is explored. Different considerations in building such a system with emphasis on the antenna and platform design is investigated. Various design elements such as type and number of antennas and their required characteristics to build the antenna array is studied. A detailed review on the present systems and their capabilities is conducted. It is shown that due to their ease of fabrication, unidirectional radiation and wide operating bandwidths, planar antennas such as tapered slot and quasi Yagi-antennas are among the most desirable structures for medical-diagnostic and monitoring applications. However, the conventional configurations of those antennas have limited practicality due to their large size. To address this limitation, a mu-negative metamaterial unit-cell loaded Yagi-antenna is shown to be an effective alternative. This antenna is used to build a semi-elliptical array that encloses the circumference of the thorax to scan the torso area. A multi-static scanning approach is devised to acquire scattered signals. The obtained results reveal that the proposed configuration has the potential to detect small amounts of fluid inside the torso and more importantly define its exact location.
Cardiac troponin T predicts occult coronary artery stenosis in patients with chronic kidney disease at the start of renal replacement therapy (2008)

We concluded that cTnT should be measured as part of a strategy for detecting asymptomatic CAS, especially multi-vessel disease in patients with CKD at the start of RRT.
Characterization of the biocontrol activity of three bacterial isolates against the phytopathogen Erwinia amylovora (2021)

Antibiotics are sprayed on apple and pear orchards to control, among other pathogens, the bacterium Erwinia amylovora, the causative agent of fire blight. As with many other pathogens, we observe the emergence of antibiotic-resistant strains of E. amylovora. Consequently, growers are looking for alternative solutions to combat fire blight. To find alternatives to antibiotics against this pathogen, we have previously isolated three bacterial strains with antagonistic and extracellular activity against E. amylovora, both in vitro and in planta, corresponding to three different bacterial genera: Here, we identified the inhibitory mode of action of each of the three isolates against E. amylovora. Isolate Bacillus amyloliquefaciens subsp. plantarum (now B. velezensis) FL50S produces several secondary metabolites including surfactins, iturins, and fengycins. Specifically, we identified oxydifficidin as the most active against E. amylovora S435. Pseudomonas poae FL10F produces an active extracellular compound against E. amylovora S435 that can be attributed to white-line-inducing principle (WLIP), a cyclic lipopeptide belonging to the viscosin subfamily (massetolide E, F, L, or viscosin). Pantoea agglomerans NY60 has a direct cell-to-cell antagonistic effect against E. amylovora S435. By screening mutants of this strain generated by random transposon insertion with decreased antagonist activity against strain S435, we identified several defective transposants. Of particular interest was a mutant in a gene coding for a Major Facilitator Superfamily (MFS) transporter corresponding to a transmembrane protein predicted to be involved in the extracytoplasmic localization of griseoluteic acid, an intermediate in the biosynthesis of the broad-spectrum phenazine antibiotic D-alanylgriseoluteic acid.
Coherence and speckle techniques for imaging through highly scattering media and optical fibers. (1997)

Holographic time gating (first arriving light) methods have been shown to be an effective way to image through highly scattering media, yet, the holographic method has the problem of placing the signal of interest on a large bias term, making the signal susceptible to noise. A complete noise analysis of the electronic holography time gating system is performed. Analytical expressions for the signal-to-noise ratio due to the dominant noise terms are derived and the effect of various system parameters on the signal-to-noise ratio is explored. Because the holographic first arriving light method is highly susceptible to noise, it is essential that optical system noise be reduced; this can be a tedious task therefore, a post processing method capable of removing fixed additive system noise is described and implemented. A detection enhancement speckle technique providing increased sensitivity to moving objects embedded within a stationary scattering medium is presented. This method is combined with the first arriving light method to create a synergistic effect, enhancing both sensitivity and resolution when imaging through highly scattering media. This concept is extended to distinguishing between various types and rates of motion through multiframe processing. A combined statistical averaging/first arriving light technique is described for phase recovery through highly scattering media. This ensemble phase information is used to enhance the time gated image by a deconvolution process. Analogous to time gating temporal coherence processes there exist spatial gating spatial coherence processes. These spatial gating methods are used to implement a direct three dimensional image fiber transmission system. An enhanced system allowing both the reference beam and the object beam to be confined to single mode fibers is also described and demonstrated. The fiber transmission system is presented from various points of view, including a general data communications approach where the system performance is analyzed in terms of data rate, probability of bit error, and modulation schemes. The spatial coherence imaging concept is extended to create a generalized optical crossbar switch.
Integration of PDMS microfluidic channel with silicon- based electromechanical cantilever sensor on a CD chip (2005)

This paper reports a novel application of centrifugal microfluidic delivery to a highly sensitive electromechanical biosensor integrated on a single chip. The microfluidic channel was designed for label-free immunoassay of a micro cantilever sensor, which has extremely low limit of detection of PSA (prostate specific antigen) up to picomolar concentration by measuring the change of resonant frequency after antibody-antigen interaction. This integration can reduce sample consumption and the number of experiment processes since no external pumping system is necessary. We demonstrate here the application of simple electrical detection for the specific PSA as an example of automatically sequential fluid delivery.
A relação entre o comprimento dos processos ciliares medidos pela biomicroscopia ultra-sônica e a duração, localização e gravidade das uveítes (2006)

Ultrasound biomicroscopy has proved to be useful in evaluating anatomical changes of ciliary processes in uveitis and in ocular hypotony, and provides a basis to, make recommendations regarding baseline screening of uveitis patients. Patients who are found to have atrophy of the ciliary processes may need a more aggressive treatment for any signs of inflammation to prevent further damage and eventual hypotony.
High-frequency dielectric spectroscopy as NDE technique for adhesively bonded composites structures (2021)

This paper discusses the application of high-frequency non-destructive techniques to the ageing study of carbon fibre reinforced plastics (CFRP) adhesively bonded composite structures. The effect of changes in the surface alignment and subsequent bulk orientation of carbon fibres on the dielectric propagation has been investigated. The ingress of moisture in the raw materials and in the joint structure is presented. The high-frequency time domain response (TDR) analysis allows the integrity of the structure to be explored and a good correlation is shown between TDR analysis and gravimetric results. This study indicates that the application of high frequency dielectric measurements is applicable to CFRP bonded structures. The dielectric study not only indicates a new way to assess the state of such a structure but is also producing new insights into the application of TDR measurement to non-isotropic materials.
Stepwise Reduction of Azapentabenzocorannulene (2019)

Abstract Mono‐ and dianions of 2‐ tert ‐butyl‐3a 2 ‐azapentabenzo[ bc , ef , hi , kl , no ]corannulene ( 1 a ) were synthesized by chemical reduction with sodium and cesium metals, and crystallized as the corresponding salts in the presence of 18‐crown‐6 ether. X‐ray diffraction analysis of the sodium salt, [{Na + (18‐crown‐6)(THF) 2 } 3 {Na + (18‐crown‐6)(THF)}( 1 a 2− ) 2 ], revealed the presence of a naked dianion. In contrast, controlled reaction of 1 a with Cs allowed the isolation of singly and doubly reduced forms of 1 a , both forming π‐complexes with cesium ions in the solid state. In [{Cs + (18‐crown‐6)}( 1 a − )]⋅THF, asymmetric binding of the Cs + ion to the concave surface of 1 a − is observed, whereas in [{Cs + (18‐crown‐6)} 2 ( 1 a 2− )], two Cs + ions bind to both the concave and convex surfaces of the dianion. The present study provides the first successful isolation and characterization of the reduced products of heteroatom‐containing buckybowl molecules.

Cross-media Relevance Computation for Multimedia Retrieval (2017)

In this paper, we summarize our works for cross-media retrieval where the queries and retrieval content are of different media types. We study cross-media retrieval in the context of two applications, i.e., ~image retrieval by textual queries, and sentence retrieval by visual queries, two popular applications in multimedia retrieval. For image retrieval by textual queries, we proposetext2image which converts computing cross-media relevance between images and textual queries to comparing the visual similarity among images.We also proposecross-media relevance fusion, a conceptual framework that combines multiple cross-media relevance estimators.These two techniques have resulted in a winning entry in the Microsoft Image Retrieval Challenge at ACM MM 2015. For sentence retrieval by visual queries, we propose to compute cross-media relevance in a visual space exclusively. We contributeWord2VisualVec, a deep neural network architecture that learns to predict a visual feature representation from textual input. With proposedWord2VisualVec model, we won the Video to Text Description task at TRECVID 2016.
