Acousto optic devices in add/drop multiplexer nodes (2002)

Two advanced network demonstrators with optical add drop multiplexing (OADM) nodes integrating acousto optic devices are presented. Based on the obtained results, a new generation of acousto optic add/drop multiplexers for dense WDM networks has been developed. We present the latest fundamental progress in the development of acousto optic devices, based on the results obtained from the OADM nodes in the Italian PROMETEO field trial and the MOSAIC experimental network testbed.
Grain-aligned YBCO superconducting current leads for conduction-cooled applications (1993)

Grain-aligned YBCO superconductors have been developed for use in a conduction-cooled, cryogen-free superconducting magnet application. A magnetic alignment technique has been used to orient the c-axis of the YBCO grains. Current leads 0.3*1.4*6.4 cm were fabricated and thermally connected between the first and second stage of a Gifford-McMahon cryocooler. The heat conduction down the leads was determined from a load map of the cryocooler. With operating temperatures of 40 K on the first stage and 10 K on the second stage, the measured heat leak was 0.15 W/lead. The YBCO current leads were used to power a conduction-cooled Nb/sub 3/Sn magnet at 10 K to 250 A. Test results for the YBCO leads are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nanoparticle Field Extraction Thruster (nanoFET): Introduction to, Analysis of, and Experimental Results from the "No Liquid" Design Option (2008)

This paper introduces a nanoparticle field extraction thruster (nanoFET) concept that does not depend on the liquid delivery of micro and nano-particles for extraction and acceleration.The no-liquid approach potentially provides important advantages such as allowing the use of smaller particles for propellant, which may offer a greater specific impulse.The most likely developmental obstacles are the adhesion of the particles to the source electrode and the cohesion between the particles.Adhesion and cohesion models are presented along with proposed methods of overcoming each.A method of using the applied charging electric field to overcome the adhesion force is investigated, which predicts that it may be possible to remove particles with diameters down to hundreds or even tens of nanometers from a planar electrode with only the application of a high strength electric field.To investigate this particle removal model, eight test cases, involving 4 particle sizes and 2 electrode materials, are presented.A method of transporting the dry particle propellant through an ultra-fine sieve prior to the charging and accelerating stages is investigated as a method of overcoming the cohesion between the particles.A simple proof-of-concept experiment is presented which indicates that this method is capable of breaking the cohesion force under appropriate conditions, which helps to guide future research.

2D Video Coding of Volumetric Video Data (2018)

Due to the increased popularity of augmented and virtual reality experiences, the interest in representing the real world in an immersive fashion has never been higher. Distributing such representations enables users all over the world to freely navigate in never seen before media experiences. Unfortunately, such representations require a large amount of data, not feasible for transmission on today's networks. Thus, efficient compression technologies are in high demand. This paper proposes an approach to compress 3D video data utilizing 2D video coding technology. The proposed solution was developed to address the needs of `tele-immersive' applications, such as virtual (VR), augmented (AR) or mixed (MR) reality with Six Degrees of Freedom (6DoF) capabilities. Volumetric video data is projected on 2D image planes and compressed using standard 2D video coding solutions. A key benefit of this approach is its compatibility with readily available 2D video coding infrastructure. Furthermore, objective and subjective evaluation shows significant improvement in coding efficiency over reference technology.
GENERATION OF TIDAL RESIDUAL CURRENT USING THE BOTTOM ROUGHNESS TO BEND FLOW DIRECTION (1998)

Nowadays in most of semi-enclosed bays water qualities have been deteriorated. Wehave proposed the method to create and control the tidal residual current by bottom roughnessfor activating the tidal exchange. In this paper we introduced the new type of bottomroughness with a function to bend the flow direction and experimentally developed the mosteffective shape. Next we tried to examine the effect of the bending roughness by numericasimulation in the model bay. As a result, it is made clear that quarters of the cylinder arrangedin two rows can get the large drag force in the normal direction of the flow and thatthe tidal exchange is promoted by the combination of the bottom roughness and the bending roughness.

Sketching with Style: Visual Search with Sketches and Aesthetic Context (2017)

We propose a novel measure of visual similarity for image retrieval that incorporates both structural and aesthetic (style) constraints. Our algorithm accepts a query as sketched shape, and a set of one or more contextual images specifying the desired visual aesthetic. A triplet network is used to learn a feature embedding capable of measuring style similarity independent of structure, delivering significant gains over previous networks for style discrimination. We incorporate this model within a hierarchical triplet network to unify and learn a joint space from two discriminatively trained streams for style and structure. We demonstrate that this space enables, for the first time, style-constrained sketch search over a diverse domain of digital artwork comprising graphics, paintings and drawings. We also briefly explore alternative query modalities.
A low-power digitally programmable impulse radio ultra wideband transmitter with pulse shape control (2012)

This paper presents a digitally programmable transmitter for ultra-wideband impulse radio using on-off keying modulation scheme. The circuit can generate pulse widths ranging from 600 ps to 1.5 ns that can be spectrally centered at frequencies ranging from 3.9 GHz to 9.3 GHz. The system allows for digital control of the transmitted power spectrum shape in order to deal with varying transmission environments. The entire transmitter is power cycled, operating from a 1.2 V supply, and consuming a simulated power as low as 0.9 mW at a 10 Mbps data rate.
Unraveling the Chemical Nature of the 3D “Hollow” Hybrid Halide Perovskites (2018)

The newly introduced class of 3D halide perovskites, termed "hollow" perovskites, has been recently demonstrated as light absorbing semiconductor materials for fabricating lead-free perovskite solar cells with enhanced efficiency and superior stability. Hollow perovskites derive from three-dimensional (3D) AMX<sub>3</sub> perovskites ( A = methylammonium (MA), formamidinium (FA); M = Sn, Pb; X = Cl, Br, I), where small molecules such as ethylenediammonium cations ( en) can be incorporated as the dication without altering the structure dimensionality. We present in this work the inherent structural properties of the hollow perovskites and expand this class of materials to the Pb-based analogues. Through a combination of physical and spectroscopic methods (XRD, gas pycnometry, <sup>1</sup>H NMR, TGA, SEM/EDX), we have assigned the general formula (A)<sub>1- x</sub>( en) <sub>x</sub>(M)<sub>1-0.7 x</sub>(X)<sub>3-0.4 x</sub> to the hollow perovskites. The incorporation of en in the 3D perovskite structure leads to massive M and X vacancies in the 3D [ MX<sub>3</sub>] framework, thus the term hollow. The resulting materials are semiconductors with significantly blue-shifted direct band gaps from 1.25 to 1.51 eV for Sn-based perovskites and from 1.53 to 2.1 eV for the Pb-based analogues. The increased structural disorder and hollow nature were validated by single crystal X-ray diffraction analysis as well as pair distribution function (PDF) analysis. Density functional theory (DFT) calculations support the experimental trends and suggest that the observed widening of the band gap is attributed to the massive M and X vacancies, which create a less connected 3D hollow structure. The resulting materials have superior air stability, where in the case of Sn-based hollow perovskites it exceeds two orders of temporal magnitude compared to the conventional full perovskites of MASnI<sub>3</sub> and FASnI<sub>3</sub>. The hollow perovskite compounds pose as a new platform of promising light absorbers that can be utilized in single junction or tandem solar cells.

Noise in erbium-doped fibre amplifiers (1988)

A series of aryl thiotetrazolylacetanilides were synthesized and found to be potent inhibitors of the HIV-1 wild type and K103N/Y181C double mutant reverse transcriptases. The incorporation of an alkynyl fragment on the aniline provided inhibitors with excellent cellular activity and extensive SAR led to the identification of one inhibitor having good oral bioavailability in rats.
The effect of lysine and valine fed during lactation on sow and litter lactation performance (1994)

Two hundred two sows (98 parity 1 and 104 parity 2 sows) were used in a 2 x 3 factorial arrangement of treatments to determine the effect of dietary valine and lysine on sow lactation performance. Treatments included two levels of lysine (.8 or 1.2%) and three valine to lysine ratios (80, 100, 120% of lysine). This experiment was conducted at a research farm of a production facility in New South Wales, Australia from January to March, 1994. For all sows, increasing dietary lysine increased litter weaning weight and litter weight gain and reduced sow weight loss. Increasing dietary valine tended to increase litter weight gain. Parity 1 sows had a greater response in litter weight gain to dietary lysine than parity 2 sows. Parity 1 sows also exhibited a linear increase in litter weight gain as dietary valine increased. Parity 2 sows had an increase in litter weight gain at the low lysine level but a decrease in litter weight gain at the high lysine level with increasing valine in the diet. Both parities had a similar reduction in sow weight loss with increasing dietary lysine. The data also were separated into sows that weaned 10 or more pigs and sows that weaned fewer than 10 pigs. Sows that weaned 10+ pigs had a greater increase in litter weaning weight and litter weight gain when dietary lysine was increased from .8 to 1.2 %. These sows also had a linear increase in litter weaning weights and litter weight gain as valine increased. Sows that weaned fewer than 10 pigs had no response to increasing lysine or valine. Serum urea nitrogen was increased by increased dietary lysine but was not affected by valine. The results demonstrate the need to increase dietary lysine and valine as milk production increases. The high-producing sow (10+ pigs weaned) requires increased lysine and valine to maximize litter growth rate and minimize sow weight loss. The independent increases in litter weaning weights from adding lysine and valine suggest separate modes of action in the high-producing sow for these amino acids in milk synthesis.; Swine Day, Manhattan, KS, November 17, 1994
Human Urinary GM2-activator Protein as a Potential Biomarker for Lung Cancer (2013)

Human urine can be obtained from most patients by noninvasive ways of collection. It is a rich source of biomarkers for diagnostic tests, therapeutic guidance and prognostic information for patients and clinicians. Recently, the protein expression pattern of urine samples from lung cancer patients and healthy controls were compared using two-dimensional gel electrophoresis (2-DE). GM2 activator protein (GM2AP) in lung cancer patients with 2.5-4.0 folds higher than that found in healthy controls was the protein of interest, and this protein was focused because it is related to tumor-associated gangliosides found in cancer progression. The aim of this study was to investigate the urinary biomarkers associated with lung cancer. First, we applied proteomic approach to confirm the increase level of GM2AP in urine samples from lung cancer patients and healthy controls. Then, the expression level of urinary GM2AP was quantified using Western blotting and Enzyme-Linked Immunosorbent Assay (ELISA). The results show that the expression level of GM2AP significantly increased in each subtype of lung cancer patients (P<0.05). In addition, nano liquid chromatography coupled online with tandem mass spectrometry (NanoLC-MS/ MS) provided evidence of an increase of GM2AP with the glycan structure identification from doublely charge at m/z 1202.1025 corresponding to the structure of (Hex)3(HexNAc)2(Fuc)1 linked with peptide (PIIVOGNVTLSVVG). Overall data suggested that the GM2AP may be associated with lung cancer and may be useful as a marker to monitor lung cancer prognosis.
A Glucose-Triptolide Conjugate Selectively Targets Cancer Cells under Hypoxia (2020)

A major hurdle in the treatment of cancer is chemoresistance induced under hypoxia that is characteristic of tumor microenvironment. Triptolide, a potent inhibitor of eukaryotic transcription, possesses potent antitumor activity. However, its clinical potential has been limited by toxicity and water solubility. To address those limitations of triptolide, we designed and synthesized glucose-triptolide conjugates (glutriptolides) and demonstrated their antitumor activity <i>in vitro</i> and <i>in vivo</i>. Herein, we identified a lead, glutriptolide-2 with an altered linker structure. Glutriptolide-2 possessed improved stability in human serum, greater selectivity toward cancer over normal cells, and increased potency against cancer cells. Glutriptolide-2 exhibits sustained antitumor activity, prolonging survival in a prostate cancer metastasis animal model. Importantly, we found that glutriptolide-2 was more potent against cancer cells under hypoxia than normoxia. Together, this work provides an attractive glutriptolide drug lead and suggests a viable strategy to overcome chemoresistance through conjugation of cytotoxic agents to glucose.
In Vitro Selection of Structure‐Switching Signaling Aptamers (2005)

Picking out probes: A novel approach permits isolation of standard DNA aptamers by in vitro selection and conversion into fluorescence signaling probes. This method comprises the isolation of DNA aptamers capable of duplex-to-complex structure switching and labeling the derived aptamers with a pair of short DNA strands with a fluorophore F and a quencher Q to create a reporter system for real-time sensing (see picture).

On Fingerprinting Images for Recognition. (1999)

A central task in multimedia systems is image management (storage and retrieval). As information is disseminated across vast networks, such as the Internet, methods of locating authored media are desirable. Digital watermarks provide a means to embed copyright and other information for identification and tracking. However, many watermarking techniques are vulnerable to distortion. We provide a means to identify images based on salient features within an image; a “fingerprint ” that survives affine distortions and can be used to recognize images. 1
Herbicide-Resistant Mutants from Tobacco Cell Cultures (1984)

Several mutants resistant to the herbicides chlorsulfuron and sulfometuron methyl were isolated form cultured cells of Nicotiana tabacum. Resistance was inherited as a single dominant or semidominant mutation in all cases. Linkage analysis of six mutants identified two unlinked genetic loci. Studies of plants homozygous for one mutation showed the mutant plants to be completely resistant to treatment with a concentration of chlorsulfuron 100 times higher than that which produces symptoms of phytotoxicity on normal plants.
The future(s) of shared data structures (2014)

This paper considers how to use futures, a well-known mechanism to manage parallel computations, to improve the performance of long-lived, mutable shared data structures in large-scale multicore systems. We show that futures can enable type-specific optimizations such as combining and elimination, improve cache locality and reduce contention. To exploit these benefits in an effective way, however, it is important to define clear notions of correctness. We propose new extensions to linearizability appropriate for method calls that return futures as results. To illustrate the utility and trade-offs of these extensions, we describe implementations of three common data structures: stacks, queues, and linked lists, designed to exploit futures. Our experimental results show that optimizations enabled by futures lead to substantial performance improvements, in some cases up to two orders of magnitude, compared to well-known lock-free alternatives.

Automatic LINAC parameter generation (2003)

In case of RF acceleration, there are three kinds of parameters; frequency, phase and amplitude of voltage. The optimum combination of these parameters cannot be derived analytically from the injection condition and the final energy because the system is not linear. In order to get the optimized set of these parameters for a new beam condition automatically, a numerical code for beam tracing was developed and installed in the NV-GSD-HE, which has ten RF acceleration cells, and in the NV-GSD-HE3, which has twelve cells. This code can simulate acceleration and deceleration of ions in the LINAC and provide the optimized RF parameters as a result. Additionally, this code can simultaneously calculate parameters of the quadrupole lenses in the LINAC for an injected beam with an assumed emittance. The calculated parameters can be automatically used for the LINAC tuning for a new beam condition as this code works with the automatic beam tuning.
