RULE-BASED EMOTION SYNTHESIS USING CONCATENATED SPEECH (2000)

Concatenative speech synthesis is increasing in popularity, as it offers higher quality output than previous formant synthesisers. However, it is based on recorded speech units, concatenative synthesis offers a lesser degree of parametric control during resynthesis. Consequently, adding pragmatic effects such as different speaking styles and emotions at the synthesis stage is fundamentally more difficult than with formant synthesis. This paper describes the results of a preliminary attempt to add emotion to concatenative synthetic speech (using BT's Laureate synthesiser), initially using techniques already applied successfully to formant synthesis. A new intonation contour (including both pitch and duration changes) was applied to the concatenated segments during production of the final audible utterance, and some of the available synthesis parameters were systematically modified to increase the affective content. The output digital speech samples were then subject to further manipulation with a waveform editing package, to produce the final output utterance. The results of this process were a small number of manually-produced utterances, but which illustrated that affective manipulations were possible on this type of synthesiser. Further work has produced rule-based implementations which allow automatic production of emotional utterances. Development of these systems will be described, and some initial results from listener studies will be presented.
CLIC4 mediates TGF-β1-induced fibroblast-to-myofibroblast transdifferentiation in ovarian cancer (2009)

Stromal myofibroblasts, activated by crosstalk signaling between the tumour and stroma, play a critical role in tumour development and progression. Chloride intracellular channel 4 (CLIC4) may be functionally import for tumour stromal fibroblast-to-myofibroblast transdifferentiaton, but the molecular mechanism of the process has not been addressed. In this study, the expression of CLIC4 in ovarian cancer tissues was analyzed by immunohistochemistry, and we used an indirect co-culture model of ovarian cancer cells and normal fibroblasts to demonstrate the molecular pathway in which CLIC4 participated during the fibroblast-to-myofibroblast transdifferentiation. The results showed that the expression of CLIC4 in 96.7% of ovarian cancer stroma and correlated with the up-regulation of myofibroblast marker alpha-SMA. Conditioned medium from ovarian cancer cells (CM) or transforming growth factor-beta1 (TGF-beta1) increased cellular reactive oxygen species (ROS) levels in fibroblasts, which initiated up-regulation of CLIC4 expression, then resulted in myofibroblast conversion. Moreover, inhibition of CLIC4 significantly reduced the expressions of factors related to the phenotype and functions of myofibroblasts, such as alpha-SMA, VEGF and HGF. These results suggest that ROS-initiated CLIC4 up-regulation is required for TGF-beta1-induced fibroblast-to-myofibroblast transdifferentiaton in ovarian cancer, indicating that inhibiting the CLIC4 might have therapeutic potential targeting tumour stroma.
Bioavailability of four ursodeoxycholic acid preparations (2000)

The significantly higher AUC and Cmax and shorter Tmax for the Canadian Ursofalk tablets compared to the UDCA capsule preparations supports better bioavailability.
Silicon Decorated Cone Shaped Carbon Nanotube Clusters for Lithium Ion Battery Anodes (2014)

In this work, we report the synthesis of an three-dimensional (3D) cone-shape CNT clusters (CCC) via chemical vapor deposition (CVD) with subsequent inductively coupled plasma (ICP) treatment. An innovative silicon decorated cone-shape CNT clusters (SCCC) is prepared by simply depositing amorphous silicon onto CCC via magnetron sputtering. The seamless connection between silicon decorated CNT cones and graphene facilitates the charge transfer in the system and suggests a binder-free technique of preparing lithium ion battery (LIB) anodes. Lithium ion batteries based on this novel 3D SCCC architecture demonstrates high reversible capacity of 1954 mAh g(-1) and excellent cycling stability (>1200 mAh g(-1) capacity with ≈ 100% coulombic efficiency after 230 cycles).
Cancer risk in long‐term users of vitamin K antagonists: A population‐based case–control study (2012)

Some evidence suggests that long-term use of vitamin K antagonists (VKAs) has a cancer chemopreventive effect. Such an effect would have considerable implications in terms of understanding tumor biology. To evaluate if long-term VKA treatment influences the risk of developing cancer, we performed a matched case-control analysis. We used data from four Danish nationwide registers. Cases were all Danish individuals with a first-time cancer diagnosis (except nonmelanoma skin cancer) between 2000 and 2009. For each case, eight controls, matched by birth year and gender, were selected from the source population by risk-set sampling. Long-term VKA use was defined as exposure to VKA for a period of 3 or more years. Conditional logistic regression was used to compute odds ratios (ORs) for cancer associated with long-term VKA exposure, adjusting for potential confounders. Prespecified subanalyses were performed for selected cancer sites, subgroups and measures of exposure. A total of 238,196 cases and 1,713,176 controls were included. The adjusted OR for cancer associated with long-term VKA exposure was 0.99 (95% CI: 0.95-1.02). Long-term VKA use was associated with increased ORs for alcohol- or obesity-related cancer sites, whereas we observed a decreased risk of prostate cancer (OR: 0.86; 95% CI: 0.78-0.95). Our study does not support a general chemopreventive effect of VKA drugs. However, in accordance with findings from previous studies, we found an inverse association between use of VKA and prostate cancer.
gvnn: Neural Network Library for Geometric Computer Vision (2016)

We introduce gvnn, a neural network library in Torch aimed towards bridging the gap between classic geometric computer vision and deep learning. Inspired by the recent success of Spatial Transformer Networks, we propose several new layers which are often used as parametric transformations on the data in geometric computer vision. These layers can be inserted within a neural network much in the spirit of the original spatial transformers and allow backpropagation to enable end-to-end learning of a network involving any domain knowledge in geometric computer vision. This opens up applications in learning invariance to 3D geometric transformation for place recognition, end-to-end visual odometry, depth estimation and unsupervised learning through warping with a parametric transformation for image reconstruction error.
Surface Enhanced Raman Scattering of Pd OECC Thin Film (2000)

We have measured the Surface Enhanced Raman scattering (SERS) spectrum of a thin film of Pd OECC (Purified Oxygen Evolution Core Complexes) on a silver mirror at room temperature. Relative to the SERS of normal Pd OCEE, the SERS of thin film Pd OECC after strong illumination shows a decrease in scattering intensity and an increase in linewidths of the bands. These indicate a change in the conformation and microenvironment of the β carotene pigment. The SERS results are consistent with the changes seen in the absorption spectrum of Pd OECC induced by strong illumination. In contrast, there is no change that can be ascribed of new vibrational bands. It is deduced that Pd OECC on the silver mirror is identical to that in solution. In summary, SERS proves to be a good method to study the photo damage mechanism in photosynthesis.
Freeze-Drying and Cryopreservation of Bacteria (2003)

Freezing and freeze-drying techniques have become standard methods for the long-term maintenance of bacterial cultures. Both methods of preservation provide varying degrees of success with different species of bacteria, and neither technique results in 100% recovery of preserved cells (1). There is no universally applicable method for the successful preservation of all bacteria, and where it is vitally important that cultures are not lost, it is advisable to use both methods in parallel.
Consensus Attention-based Neural Networks for Chinese Reading Comprehension (2016)

Reading comprehension has embraced a booming in recent NLP research. Several institutes have released the Cloze-style reading comprehension data, and these have greatly accelerated the research of machine comprehension. In this work, we firstly present Chinese reading comprehension datasets, which consist of People Daily news dataset and Children's Fairy Tale (CFT) dataset. Also, we propose a consensus attention-based neural network architecture to tackle the Cloze-style reading comprehension problem, which aims to induce a consensus attention over every words in the query. Experimental results show that the proposed neural network significantly outperforms the state-of-the-art baselines in several public datasets. Furthermore, we setup a baseline for Chinese reading comprehension task, and hopefully this would speed up the process for future research.
Reflex (2012)

To accomplish frequent, simple tasks with high efficiency, it is necessary to leverage low-power, microcontroller-like processors that are increasingly available on mobile systems. However, existing solutions require developers to directly program the low-power processors and carefully manage inter-processor communication. We present Reflex, a suite of compiler and runtime techniques that significantly lower the barrier for developers to leverage such low-power processors. The heart of Reflex is a software Distributed Shared Memory (DSM) that enables shared memory objects with release consistency among code running on loosely coupled processors. In order to achieve high energy efficiency without sacrificing performance much, the Reflex DSM leverages (i) extreme architectural asymmetry between low-power processors and powerful central processors, (ii) aggressive compile-time optimization, and (iii) a minimalist runtime that supports efficient message passing and event-driven execution. We report a complete realization of Reflex that runs on a TI OMAP4430-based development platform as well as on a custom tri-processor mobile platform. Using smartphone sensing applications reported in recent literature, we show that Reflex supports a programming style very close to contemporary smartphone programming. Compared to message passing, the Reflex DSM greatly reduces efforts in programming heterogeneous smartphones, eliminating up to 38% of the source lines of application code. Compared to running the same applications on existing smartphones, Reflex reduces the average system power consumption by up to 81%.
Electronic Pre-equalization Technologies using High-Speed DAC (2011)

Sound, shock waves shatter kidney stones. (1983)

Surgical treatment of kidney stones is undergoing very exciting changes, according to Lynwood H. Smith, MD, professor of medicine at the Mayo Clinic in Rochester, Minn. Speaking at a National Kidney Foundation symposium in Washington, DC, Smith, a nephrologist, summarized recently reported results using two new procedures: percutaneous ultrasonic lithotripsy (PUL) and extracorporeal shock wave lithotripsy (ESWL). Both procedures are used only for stones that otherwise would have to be removed surgically. In PUL, a radiologist, using local anesthesia, first introduces a guide wire percutaneously through the flank into the kidney. The next day, using general anesthesia, dilators are placed over the guide wire. Once dilation is sufficient, a tube resembling a small cystoscope is inserted into the kidney's collecting system and up against the stone. An ultrasoundgenerating instrument developed by European urologists Peter Alkin, MD, and Michael Marberger, MD, is then passed through the tube and used to shatter
Free-standing plasmonic metal-dielectric-metal bandpass filter with high transmission efficiency (2017)

Plasmonic spectrum filtering devices based on metallic nanostructures have attracted wide attention due to their good reliability, ease of fabrication, and wideband tunability. However, the presence of thick substrate significantly limits the structure's longitudinal size for further optoelectronic integration and reduces the devices' performance. Here we propose and demonstrate an ultra-thin plasmonic bandpass filter based on free-standing periodic metal-dielectric-metal stack geometry working in the near-infrared wavelength range. The coupling between free-space electromagnetic waves and spatially confined plasmonic modes in the designed structure is systematically investigated. As demonstrated in the calculation and experiment, the free-standing plasmonic filters have more than 90% transmission efficiency and superior angular tolerance. The experimental results are in good agreement with the theoretical calculations. These artificial nanostructured filtering devices may find potential applications in the extremely compact device architectures.

THE EVOLUTION OF ROTATING SILICON SURFACES DURING ION BOMBARDMENT (1998)

Under a wide range of conditions, ion bombardment of nominally flat substrates results in the formation of macroscopic hummock features. We present a theoretical model of this process which details the evolution of hummocks on rotating substrates. The formation of facetted hummocks, the interaction and coalescence of two hummocks, and global properties such as the hummock size distribution are described. These results are used to interpret experimentally observed hummocks on Ar+ sputtered, rotating Si(100) substrates.
Use of nickel and iron additions as sintering aids for titanium diboride (1996)

The effects of Ni and Fe used as sintering aids in the pressureless sintering of commercially available titanium diboride (TiB2) powder have been investigated. The specimens prepared were characterised using optical microscopy scanning electron microscopy and X-ray diffraction. It was found that sintering of TiB2-Ni mixtures gave a maximum relative density of 88.6% when 8.0 wt-%Ni was added and sintered at 1800 degrees C, and that in specimens sintered at 2000 degrees C, Ni additions caused severe microcracking, which was attributed to an increase in the average gi ain size. In the case of TiB2-Fe mixtures, the sintered relative density increased to 89.2% with art addition of 0.4 wt-%Fe, and did not increase further with the addition of higher amounts of Fe at a particular sintering temperature. With both types of additive, the density of specimens sintered at 2000 degrees C was lower compared with specimens sintered at 1800 degrees C, mainly because of evaporation of phases containing Ni or Fe.
9‐Fluorenylphosphines for the Pd‐Catalyzed Sonogashira, Suzuki, and Buchwald–Hartwig Coupling Reactions in Organic Solvents and Water (2007)

The lithiation/alkylation of fluorene leads to various 9-alkyl-fluorenes (alkyl=Me, Et, iPr, -Pr, -C18H25) in>95% yields, for which lithiation and reaction with R2PCl (R=Cy, iPr, tBu) generates 9-alkyl, 9-PR2-fluorenes which constitute electron-rich and bulky phosphine ligands. The in-situ-formed palladium-phosphine complexes ([Na2PdCl4], phosphonium salt, base, substrates) were tested in the Sonogashira, Suzuki, and Buchwald-Hartwig reactions of aryl chlorides and aryl bromides in organic solvents. The Sonogashira coupling of aryl chlorides at 100-120 degrees C leads to>90% yields with 1 mol% of Pd catalyst. The Suzuki coupling of aryl chlorides typically requires 0.05 mol% of Pd catalyst at 100 degrees C in dioxane for quantitative product formation. To carry out "green" cross-coupling reactions in water, 9-ethylfluorenyldicyclohexylphosphine was reacted in sulphuric acid to generate the respective 2-sulfonated phosphonium salt. The Suzuki coupling of activated aryl chlorides by using this water-soluble catalyst requires only 0.01 mol% of Pd catalyst, while a wide range of aryl chlorides can be quantitatively converted into the respective coupling products by using 0.1-0.5 mol% of catalyst in pure water at 100 degrees C. Difficult substrate combinations, such as naphthylboronic acid or 3-pyridylboronic acid and aryl chlorides are coupled at 100 degrees C by using 0.1-0.5 mol% of catalyst in pure water to obtain the respective N-heterocycles in quantitative yields. The copper-free aqueous Sonogashira coupling of aryl bromides generates the respective tolane derivatives in>95% yield.
Reliability and validity of self‐paced walking time measures for knee osteoarthritis (1994)

This study assessed the reliability and validity of self-paced walking time as an outcome measure for osteoarthritis (OA) of the knee. The 13-m timed walking tests were carried out twice on two separate occasions for 15 patients using photocells. Validity was examined by comparing the walking time data with results of other methodologies for evaluating osteoarthritic gait. As indicated by intra- and inter-day intraclass correlation coefficients of 0.97 and 0.88 the gait measurements were reliable. The measurements also compared favorably with a validated subjective functional index for knee OA (P < 0.01). The findings suggest that measurements of self-paced walking time can provide both reliable and valid data for evaluating functional performance in this patient population.
A method of medical image enhancement using wavelet-coefficient mapping functions (2003)

An approach to medical image enhancement is proposed. In this method, non-linear mapping functions are derived for projecting a set of discrete wavelet transform (DWT) coefficients to a new set of DWT coefficients. The mapped coefficients are then inverse wavelet transformed. Applications of the proposed method to the chest x-ray images and mammograms with subtle micro-calcifications are shown. To validate the effectiveness of the proposed method, we compared the results to those obtained by the fast Fourier transform (FFT) and the conventional wavelet-based (CWB) methods. Our preliminary results strongly suggest that the proposed method offers considerably improved enhancement capability over the FFT and CWB methods.
Communication Over MIMO X Channels: Interference Alignment, Decomposition, and Performance Analysis (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <?Pub Dtl=""?>In a multiple-antenna system with two transmitters and two receivers, a scenario of data communication, known as the X channel, is studied in which each receiver receives data from both transmitters. In this scenario, it is assumed that each transmitter is unaware of the other transmitter's data (noncooperative scenario). This system can be considered as a combination of two broadcast channels (from the transmitters' points of view) and two multiple-access channels (from the receivers' points of view). Taking advantage of both perspectives, two signaling schemes for such a scenario are developed. In these schemes, some linear filters are employed at the transmitters and at the receivers which decompose the system into either two noninterfering multiple-antenna broadcast subchannels or two noninterfering multiple-antenna multiple-access subchannels. The main objective in the design of the filters is to exploit the structure of the channel matrices to achieve the highest multiplexing gain (MG). It is shown that the proposed noncooperative signaling schemes outperform other known noncooperative schemes in terms of the achievable MG. In particular, it is shown that in some specific cases, the achieved MG is the same as the MG of the system if full cooperation is provided either between the transmitters or between the receivers. </para>
Optimizing Storage Performance for VM-Based Mobile Computing (2013)

This article investigates the transient use of free local storage for improving performance in VM-based mobile computing systems implemented as thick clients on host PCs. We use the term TransientPC systems to refer to these types of systems. The solution we propose, called TransPart , uses the higher-performing local storage of host hardware to speed up performance-critical operations. Our solution constructs a virtual storage device on demand (which we call transient storage ) by borrowing free disk blocks from the host’s storage. In this article, we present the design, implementation, and evaluation of a TransPart prototype, which requires no modifications to the software or hardware of a host computer. Experimental results confirm that TransPart offers low overhead and startup cost, while improving user experience.
Filler retention in papermaking by polymeric and microparticulate retention aid systems (2004)

Mineral pigments are added to paper with the aim of improving its optical and printing properties. The colloidal behavior of calcium carbonate filler shows a dependence on the quality of water used in suspensions, presence of dissolved and colloidal substances and type of polymer used as a retention aid. The role of the retention aids is to attach colloidal particles, such as fines and mineral pigments, to pulp fibers before or during the paper is made. Two very different single-component retention aids were utilized in calcium carbonate fillers destabilization and deposition on fibers. Cationic polyethylenimine destabilized or facilitated deposition of the filler on fibers by a charge neutralization mechanism while cationic polyacrylamide flocculated or deposited the filler on fibers via a bridging mechanism.
Synthesis and characterization of novel luminescent polymers with alternate phenothiazine and divinylbenzene units (2002)

Abstract Novel luminescent polymers ( P1 and P2 ) carrying alternate phenothiazine and divinylbenzene units were synthesized via the Wittig reaction. Absorption, fluorescence, and cyclic voltammetric methods were applied to investigate their optical and electrochemical properties. The photoluminescence (PL) maxima of P1 and P2 were 559 and 568 nm, respectively. Compared with reported hole‐transport groups such as carbazole, alkyldiphenylamine, triphenylamine, and iminodibenzyl chromophores, phenothiazine moieties in P1 and P2 bathochromically shift the PL maxima and narrow the band gaps. Their relative PL efficiencies were about 0.5 and 0.3 in solution and in the film state, respectively. Moreover, highest occupied molecular orbitals of P1 (4.78 eV) and P2 (4.74 eV) were even higher than the work function of ITO electrode (4.8 eV). The threshold electric fields of the Al/ P1 (or P2 )/ITO device were about 1.52–1.63 · 10 6 V/cm, which were smaller than 1.73 · 10 6 V/cm of P3 , consisting of alternate iminodibenzyl and divinylbenzene units. © 2002 Wiley Periodicals, Inc.
