Efficient Infrared Electroluminescent Devices Using Solution‐Processed Colloidal Quantum Dots (2005)

Abstract We report efficient electroluminescence in the near‐infrared from PbS–MEH‐PPV (poly(2‐methoxy‐5‐(2′‐ethylhexyloxy)‐1,4‐phenylenevinylene)) large‐area, solution‐cast nanocomposite devices. We employ multivariate optimization of the structural and materials components that govern the radiative, energy‐transfer, and bipolar‐injection efficiencies into the devices. As a result, we report an external electroluminescence quantum efficiency of 0.27 %, which corresponds to an internal electroluminescence quantum efficiency of 1.9 %. The very best devices exhibit internal‐radiative‐efficiency‐limited performance and not transport‐ or capture‐limited performance, indicating that further gains in efficiency may be achieved if the internal radiative efficiency of the nanocrystal–polymer composite can be further increased without compromising transfer and device bipolar‐injection efficiency.
CSTR VCTK Corpus: English Multi-speaker Corpus for CSTR Voice Cloning Toolkit (version 0.92) (2019)

This CSTR VCTK Corpus includes speech data uttered by 110 English speakers with various accents. Each speaker reads out about 400 sentences, which were selected from a newspaper, the rainbow passage and an elicitation paragraph used for the speech accent archive. The newspaper texts were taken from Herald Glasgow, with permission from Herald & Times Group. Each speaker has a different set of the newspaper texts selected based a greedy algorithm that increases the contextual and phonetic coverage. The details of the text selection algorithms are described in the following paper: C. Veaux, J. Yamagishi and S. King, "The voice bank corpus: Design, collection and data analysis of a large regional accent speech database," https://doi.org/10.1109/ICSDA.2013.6709856 The rainbow passage and elicitation paragraph are the same for all speakers. The rainbow passage can be found at International Dialects of English Archive: (http://web.ku.edu/~idea/readings/rainbow.htm). The elicitation paragraph is identical to the one used for the speech accent archive (http://accent.gmu.edu). The details of the the speech accent archive can be found at http://www.ualberta.ca/~aacl2009/PDFs/WeinbergerKunath2009AACL.pdf All speech data was recorded using an identical recording setup: an omni-directional microphone (DPA 4035) and a small diaphragm condenser microphone with very wide bandwidth (Sennheiser MKH 800), 96kHz sampling frequency at 24 bits and in a hemi-anechoic chamber of the University of Edinburgh. (However, two speakers, p280 and p315 had technical issues of the audio recordings using MKH 800). All recordings were converted into 16 bits, were downsampled to 48 kHz, and were manually end-pointed. This corpus was originally aimed for HMM-based text-to-speech synthesis systems, especially for speaker-adaptive HMM-based speech synthesis that uses average voice models trained on multiple speakers and speaker adaptation technologies. This corpus is also suitable for DNN-based multi-speaker text-to-speech synthesis systems and neural waveform modeling. The dataset was was referenced in the Google DeepMind work on WaveNet: https://arxiv.org/pdf/1609.03499.pdf . Please note while text files containing transcripts of the speech are provided for 109 of the 110 recordings, in the '/txt' folder, the 'p315' text was lost due to a hard disk error.
A Case of Primary Pericardial Malignant Mesothelioma (2004)

Primary pericardial malignant mesothelioma is a lethal and rare cardiac neoplasm of mesodermal origin. Most cases are associated with history of pericarditis with constriction and/or tamponade. Authors experienced a case of primary pericardial malignant mesothelioma in a 55-year old female who had suffered from dyspnea and chest pain. Pericardial nodules revealed intense uptake by FDG-PET scan and confirmed as primary pericardial malignant mesothelioma by thoracoscopic biopsy. Here we report this case with a brief review of the relevant literatures.
A New Determination of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi mathvariant="italic">G</mml:mi></mml:math>Using Two Methods (2001)

We present the results of a measurement of G made with a torsion-strip balance used in two substantially independent ways. The two results agree to within their respective uncertainties; the correlation coefficient of the two methods is -0.18. The result is G = 6.675 59(27)x10(-11) m(3) kg(-1) s(-2) with a standard uncertainty of 4.1 parts in 10(5). Our result is 2 parts in 10(4) higher than the recent result of Gundlach and Merkowitz.
Learning Concept Embeddings for Query Expansion by Quantum Entropy Minimization (2014)

In web search, users queries are formulated using only few terms and term-matching retrieval functions could fail at retrieving relevant documents. Given a user query, the technique of query expansion (QE) consists in selecting related terms that could enhance the likelihood of retrieving relevant documents. Selecting such expansion terms is challenging and requires a computational framework capable of encoding complex semantic relationships. In this paper, we propose a novel method for learning, in a supervised way, semantic representations for words and phrases. By embedding queries and documents in special matrices, our model disposes of an increased representational power with respect to existing approaches adopting a vector representation. We show that our model produces high-quality query expansion terms. Our expansion increase IR measures beyond expansion from current word-embeddings models and well-established traditional QE methods.
Lattice-Mismatched Growth and Transport Properties of InAlAs/InGaAs Heterostructures on GaAs Substrates (1989)

We report on the lattice-mismatched growth of In 0.53 Ga 0.47 As/In 0.52 Al 0.48 As modulation-doped heterostructures on GaAs substrates by molecular beam epitaxy. A buffer layer structure and its growth conditions were optimized. As a result, we obtained a sample with a mirrorlike surface which exhibits electron mobility of 10500 cm 2 /V·s and 48500 cm 2 /V·s at 300 K and 77 K, respectively. These values are comparable to those obtained in lattice-matched structures grown on InP substrates. To our knowledge, the room temperature mobility is the highest ever reported in a modulation-doped heterostructure grown on a GaAs substrate.
Purification and partial characterization of a C1q inhibitor from the membranes of human peripheral blood lymphocytes. (1982)

Abstract An activity that is capable of precipitating highly purified C1q and inhibiting the C1q-dependent biologic reactions was solubilized from the membranes of 1 × 1010 normal human peripheral B lymphocytes, and has been designated membrane-derived C1 q inhibitor (M-C1q INH). M-C1q INH has an apparent m.w. of 1.0 to 2 × 106 as assessed by gel filtration on Sepharose 6B, and an electrophoretic mobility of −6.7 × 10−5 cm2V−1sec−1 on cellulose acetate at pH 8.6. Monospecific antiserum raised in rabbits to isolated M-C1q INH as well as polyvalent antiserum raised in rabbits to purified peripheral blood B lymphocytes were found to react with unfractionated, solubilized membrane proteins as well as C1q INH derived from both lymphocytes and lymphoblastoid (Raji) cells. Upon Immunoelectrophoresis of M-C1q INH and normal human serum, the antisera were found to detect a material that migrated with an electrophoretic behavior similar to that of isolated M-C1q INH. Purified M-C1q INH was able to bind and precipitate highly purified C1q in solution or in 0.8% agarose, at pH 7.2. Such binding was optimal under conditions of low ionic strength. Preincubation of purified C1q with M-C1q INH at 37°C for 60 min abrogated C1q hemolytic activity in a dose-dependent fashion. No inhibition was observed, however, when the inhibitor was first pretreated with the monospecific antiserum raised against isolated M-C1q INH before incubation with the C1q. In addition, uptake of 125I C1q by B lymphocytes was effectively blocked by prior treatment of the labeled C1q with the inhibitor, suggesting the inhibitor binds to the region of the C1q molecule through which it binds to cellular receptors. Preliminary chemical analyses of M-C1q INH suggests it consists of 23% uronic acid and 21% galactosamine. Comparison of amino acid data seems to indicate that the serum C1q INH and M-C1q INH might not be identical. Furthermore, digestion of M-C1q INH with chondroitinase ABC did not affect its properties. Thus, the evidence presented seems to indicate that the M-C1q INH could represent a cell membrane receptor for human C1q.
Microbes in food processing technology (1994)

There is an increasing understanding that the microbial quality of a certain food is the result of a chain of events. It is clear that the microbial safety of food can only be guaranteed when the overall processing, including the production of raw materials, distribution and handling by the consumer are taken into consideration. Therefore, the microbiological quality assurance of foods is not only a matter of control, but also of a careful design of the total process chain. Food industry has now generally adapted quality assurance systems and is implementing the Hazard Analysis Critical Control Point (HACCP) concept. Rapid microbiological monitoring systems should be used in these cases. There is a need for rapid and simple microbiological tests which can be adapted to the technology and logistics of specific production processes. Traditional microbiological methods generally do not meet these high requirements. This paper discusses the tests, based on molecular biological principles, to detect and identify microbes in food-processing chains. Tests based on DNA technology are discussed, including in vitro DNA amplification like the polymerase chain reaction (PCR) method and identifications based on RFLP, RAPD and DNA fingerprinting analysis. PCR-haled methodology can be used for the rapid detection of microbes in food manufacturing environments. In addition, DNA fingerprinting methods are suitable for investigating sources and routes of microbial contamination in the food cycle.
Development of a High Hang Weight Expandable Liner Hanger for Deepwater Applications (2017)

Abstract Liner hangers are expected to maintain anchor capability and pressure integrity throughout the life of the well. For deepwater applications where hang weights, temperature requirements, and operational expenses can be considerably higher, liner-hanger performance is even more important. A new concept was proposed to make expandable liner hangers (ELHs) more robust and less sensitive to high temperatures and temperature variations. The concept of a new metal-sealing ELH was initiated to provide metal-to-metal sealing capability at elevated temperatures and in applications that require additional anchor capacity. During the development process, finite element analysis (FEA) and numerical optimization techniques were used to fine-tune the concept and optimize a 7- × 9 5/8-in. hanger design. The concept was extended to multiple sizes and made more robust for downhole environments after successful testing validations. The optimized 7- × 9 5/8-in. hanger design was then physically tested and validated at 400°F. The liner hanger passed all executed testing including pressure testing from above and below and hang-weight testing. Results indicated that the hanger design is insensitive to downhole temperatures and has a high hang-weight capacity. The concept has since been extended to include multiple sizes and more robust features for downhole environments. Field trials to date have been successful in several regions, including the Gulf of Mexico, North Sea, West Africa, and Malaysia. This paper presents a new ELH design and discusses the significant time and cost reductions resulting from the development using numerical analysis and optimization. Case histories of successful field trials are also presented. The new concept ELH has been proven to provide robust high-hanging capacity for a wide range of temperatures during validation testing and field trials.
A Nanoscale Vertical Double-Gate Single-Transistor Capacitorless DRAM (2008)

We experimentally demonstrate and characterize a vertical (current flow that is perpendicular to the wafer) source (bottom)/drain (top) double-gate capacitorless single-transistor DRAM on a bulk silicon wafer. We have electrically measured retention times in excess of 25 ms. Device fabrication was facilitated by several key process innovations, which allow the device to also be integrated with planar devices using minimal additional process steps. The structure results in a highly scalable DRAM down to 22-nm technology node.

Resource assessment for future generations of tidal-stream energy arrays (2015)

Tidal-stream energy devices currently require spring tide velocities (SV) in excess of 2.5 m/s and water depths in the range 25–50 m. The tidal-stream energy resource of the Irish Sea, a key strategic region for development, was analysed using a 3D hydrodynamic model assuming existing, and potential future technology. Three computational grid resolutions and two boundary forcing products were used within model configuration, each being extensively validated. A limited resource (annual mean of 4 TJ within a 90 km2 extent) was calculated assuming current turbine technology, with limited scope for long-term sustainability of the industry. Analysis revealed that the resource could increase seven fold if technology were developed to efficiently harvest tidal-streams 20% lower than currently required (SV > 2 m/s) and be deployed in any water depths greater than 25 m. Moreover, there is considerable misalignment between the flood and ebb current directions, which may reduce the practical resource. An average error within the assumption of rectilinear flow was calculated to be 20°, but this error reduced to ∼3° if lower velocity or deeper water sites were included. We found resource estimation is sensitive to hydrodynamic model resolution, and finer spatial resolution (<500 m) is required for regional-scale resource assessment when considering future tidal-stream energy strategies.
A comparison of faces scales for the measurement of pediatric pain: childrenʼs and parents’ ratings (1999)

Faces scales have become the most popular approach to eliciting children's self-reports of pain, although different formats are available. The present study examined: (a) the potential for bias in children's self-reported ratings of clinical pain when using scales with smiling rather than neutral 'no pain' faces; (b) levels of agreement between child and parent reports of pain using different faces scales; and (c) preferences for scales by children and parents. Participants were 75 children between the ages of 5 and 12 years undergoing venepuncture, and their parents. Following venepuncture, children and parents independently rated the child's pain using five different randomly presented faces scales and indicated which of the scales they preferred and why. Children's ratings across scales were very highly correlated; however, they rated significantly more pain when using scales with a smiling rather than a neutral 'no pain' face. Girls reported significantly greater levels of pain than boys, regardless of scale type. There were no age differences in children's pain reports. Parents' ratings across scales were also highly correlated; however, parents also had higher pain ratings using scales with smiling 'no pain' faces. The level of agreement between child and parent reports of pain was low and did not vary as a function of the scale type used; parents overestimated their children's pain using all five scales. Children and parents preferred scales that they perceived to be happy and cartoon-like. The results of this study indicate that subtle variations in the format of faces scales do influence children's and parents' ratings of pain in clinical settings.
Coherent heterodyne time-domain spectrometry covering the entire “terahertz gap” (2008)

Terahertz waves, electromagnetic radiation in the spectral region commonly defined between 0.3 and 10THz, allow innovative sensing and imaging techniques that can provide spectroscopic information unavailable at other wavelengths. However, simultaneously intense, broadband, and coherent spectroscopic measurement remains challenging. We report spectrometry using gases ionized by femtosecond pulses to generate and sense broadband terahertz pulses. Using a coherent heterodyne technique, the measurements span the “terahertz gap” with ⩾10% of the maximum signal from 0.3to10THz. This spectrometer, using a recycled optical probe beam and coherent detection, offers a high field strength and time-resolved measurement.
Theoretical Foundations for High Performance Order Tracking with the Vold-Kalman Tracking Filter (1997)

<div class="htmlview paragraph">Vold and Leuridan [<span class="xref">1</span>] introduced in 1993 an algorithm for high resolution, slew rate independent order tracking based on the concepts of Kalman filters [<span class="xref">5</span>, <span class="xref">6</span>]. The algorithm has been highly successful as implemented in a commercial software system in solving data analysis problems previously intractable with other analysis methods. At the same time certain deficiencies have surfaced, prompting the development of an improved formulation. This paper presents for the first time the second generation algorithm and its theoretical foundations. The new algorithm allows for the simultaneous estimation of multiple orders, effectively decoupling close and crossing orders. This is especially important for acoustics applications, where order crossings cause transient beating events. The algorithm now allows for a much wider range of filter shapes, such that signals with sideband modulations are processed with high fidelity. Finally, systems with radical RPM changes, such as transmissions, are tracked also through the transient events associated with abrupt changes in inertia and boundary conditions. The order functions are extracted without phase error, and may hence be used in synthesis applications for sound quality and laboratory simulations.</div>
Investigation of the Young's Modulus of Fibers in an Electrospun PCL Scaffold Using AFM and its Correlation to cell Attachment (2011)

Seeding a layer of cells at specific depths within scaffolds is an important optimization parameter for bi-layer skin models. Experimental investigation has been performed to investigate the effect of fiber diameter and its mechanical property on the depth of cell seeding of for electrospun fiber scaffold. Polycaprolactone (PCL) is used to generate scaffolds that are submicron (400nm) to micron (1100nm) using electro-spinning. 3T3 fibroblasts were seeded on the electro-spun fiber scaffold mat of 50-70 microns thickness in this study. In order to investigate the effect of fiber diameter on cell migration, first, the electrospun fiber scaffold was studied for variation of mechanical properties as a function of fiber diameters. Atomic force microscopy (AFM) was used to investigate the Young’s modulus (E) values as a function of fiber diameter. It was identified that as the fiber diameter increases, the Young’s modulus values decreases considerably from 1.9GPa to 600MPa. The variation in E is correlated with cell seeding depth as a function of vacuum pressure. A higher E value led to a lower depth of cell seeding (closer to the surface) indicating that nano-fibrous scaffolds offer larger resistance to cell movement compared to microfibrous scaffolds
Silicon as a millimeter-wave monolithically integrated substrate - A new look (1981)

Materials suitable for use as monolithic substrates are summarized. A study of the properties of silicon substrates as transmission line media shows that serious consideration should be given to them for use at mm-wave frequencies. It is concluded that for silicon resistivities of 2000 ohm-cm or greater, microstrip loss in silicon at mm-wave frequencies is only slightly higher than that in GaAs or alumina. The cross section width of a transmission line represents an appreciable part of a wavelength when microstrip is used as an impedance transformer at mm-wave frequencies. Therefore, substrate thickness (using the latest dispersion characteristics) is especially considered in circuit design. These effects on the design of 3-dB interdigitated and branch-line couplers are demonstrated. Fabrication of silicon IMPATT diodes operating up to 200 GHz has been ac­complished by novel techniques that maintain the silicon's high resistivity. We report on diodes yielding 25 mW cw at 102 GHz, 16 mW cw at 132 GHz, and 1 mW at 195 GHz. The techniques described are ion implantation, laser annealing, unique secondary-ion mass spectrometry (SIMS) profile diagnostics, and novel wafer thinning. The utilization of these technologies paves the way for the pro­cessing of silicon monolithic mm-wave integrated circuits.
The emerging role of miR-506 in cancer (2016)

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. They are involved in almost all biological processes, and many have been identified as potential oncogenes or tumor suppressor genes. miR-506 was recently discovered to play pivotal roles in regulating cell proliferation, differentiation, migration and invasion. Dysregulation of miR-506 has been demonstrated in multiple types of cancers; however, whether it functions as an oncogene or a tumor suppressor seems to be context-dependent. Altered miR-506 expression in cancer is caused by promoter methylation and changes in upstream transcription factors. In this review, we summarize the current understanding of the diverse roles and underlying mechanisms of miR-506 and its involvement in cancer, and suggest the potential therapeutic strategy based on miR-506.
Cooperative control of full electric braking system with independently driven four wheels (2006)

As the spread of the electric vehicle advance, the braking system of EVs tends to change from the hydraulic drive to the full electric drive. This paper says about a full electric braking system using a regenerative brake and an electromechanical brake. Especially, two cooperative control methods between the regenerative brake of each motor and the electromechanical brake are proposed. One method is open-loop control and another is feedback control of braking force. A simulator using an EV with independently driven four wheels was constructed and the characteristics of two cooperative braking controls were clarified
Small‐molecule stabilization of the p53 – 14‐3‐3 protein‐protein interaction (2017)

14-3-3 proteins are positive regulators of the tumor suppressor p53, the mutation of which is implicated in many human cancers. Current strategies for targeting of p53 involve restoration of wild-type function or inhibition of the interaction with MDM2, its key negative regulator. Despite the efficacy of these strategies, the alternate approach of stabilizing the interaction of p53 with positive regulators and, thus, enhancing tumor suppressor activity, has not been explored. Here, we report the first example of small-molecule stabilization of the 14-3-3 - p53 protein-protein interaction (PPI) and demonstrate the potential of this approach as a therapeutic modality. We also observed a disconnect between biophysical and crystallographic data in the presence of a stabilizing molecule, which is unusual in 14-3-3 PPIs.
