Photo-Consistent Reconstruction of Semitransparent Scenes by Density-Sheet Decomposition (2007)

This paper considers the problem of reconstructing visually realistic 3D models of dynamic semitransparent scenes, such as fire, from a very small set of simultaneous views (even two). We show that this problem is equivalent to a severely underconstrained computerized tomography problem, for which traditional methods break down. Our approach is based on the observation that every pair of photographs of a semitransparent scene defines a unique density field, called a Density Sheet, that 1) concentrates all its density on one connected, semitransparent surface, 2) reproduces the two photos exactly, and 3) is the most spatially compact density field that does so. From this observation, we reduce reconstruction to the convex combination of sheet-like density fields, each of which is derived from the Density Sheet of two input views. We have applied this method specifically to the problem of reconstructing 3D models of fire. Experimental results suggest that this method enables high-quality view synthesis without overfitting artifacts.
DEco Arch: Trust and Reputation Aware Service Brokering Architecture in Digital Ecosystems (2007)

Awareness of social ratings such as reputation, credibility and trustworthiness plays a key role in digital ecosystems where autonomous agents collaborate in order to publish their services or search for services. The integration of these social ratings along with attribute matching presents a novel approach and strengthens stability and confidence in autonomous distributed communities. This ensures that the selection of the optimal service is guaranteed while minimizing general security and business related risks. In this paper we discuss a framework for service registration which is hosted in a P2P environment. Service consumers can discover services which are grouped based on their contexts. Both, services and group alliances are defined through semantically enriched metadata and social ratings.
Thermally Induced Defect Behavior and Effective Intrinsic Gettering Sink in Silicon Wafers (1981)

Dislocation‐free Czochralski silicon wafers have been subjected to a two‐step annealing procedure to explore the intrinsic gettering (IG) phenomenon and the behavior of thermally induced microdefects using infrared absorption, preferential etching, and transmission electron microscopy (TEM). As a result, it is found that plastic lattice deformation introduced by dislocation and/or stacking faults is necessary for effective IG sinks. In spite of their extremely high density, microprecipitates with elastic strain but no plastic deformation do not result in effective IG. TEM observations clarify the change in density and/or structure of inner defects by precipitate dissolving after the second annealing at high temperature.
Radiotherapy with beams of carbon ions (2005)

In cancer treatment, the introduction of MeV bremsstrahlung photons has been instrumental in delivering higher doses to deep-seated tumours, while reducing the doses absorbed by the surrounding healthy tissues. Beams of protons and carbon ions have a much more favourable dose-depth distribution than photons (called 'x-rays' by medical doctors) and are the new frontiers of cancer radiation therapy. Section 2 presents the status of the first form of hadrontherapy which uses beams of 200–250 MeV protons. The central part of this review is devoted to the discussion of the physical, radiobiological and clinical bases of the use of 400 MeV µ−1 carbon ions in the treatment of radio-resistant tumours. These resist irradiation with photon as well as proton beams. The following section describes the carbon ion facilities that are either running or under construction. Finally, the projects recently approved or proposed are reviewed here.
Charcot-Marie-Tooth disease due to a de novo mutation of the <i>RAB7</i> gene (2006)

We report a 32-year-old patient with Charcot-Marie-Tooth (CMT2B) including foot ulcerations. Genetic analysis identified a de novo mutation in the small GTP-ase late endosomal RAB7 gene, consisting of a c.471G>C, p.Lys157Asn missense mutation. This observation strongly supports the hypothesis that RAB7 mutations are responsible for CMT2B.

Experimental Comparison of d-Rectangle Intersection Algorithms Applied to HLA Data Distribution (1997)

The High Level Architecture (HLA) is a standard for constructing distributed simulations. The Data Distribution Management services of HLA reduce the amount of data delivered to an HLA federate by allowing communications connections to be based on federates’ expressed data production and requirements. At the core of determining which connections to make is a geometric problem: finding the dynamic intersection of d-dimensional rectilinear hyperrectangles in d-space. Four different algorithms for solving that problem are described, including a new one developed through application of a data structure from computational geometry. Those algorithms are then compared in an experiment designed to reveal how well they perform in the specific context of the data distribution application. Both intersection performance and connectivity efficiency results are reported.
Modelling Volatility of the BDT/USD Exchange Rate with GARCH Model (2012)

The key objective of the study is to explore the application of GARCH type models, like GARCH; EGARCH; TARCH; and PARCH; when applied to task for modelling the BDT/USD exchange rate using the daily foreign exchange rate series fixed up by Bangladesh Bank. This study is conducted by benchmarking their results with AR and ARMA models.The BDT/USD time series from July 03, 2006 to April 30, 2012 are used for the study purpose out of which in-sample and out-of-sample date set cover from July 03, 2006 to May 13, 2010 and May 14, 2010 to April 30, 2012 respectively.The major finding of this study is that all GARCH type models demonstrate that past volatility of exchange rate significantly influence current volatility. Both the AR and ARMA models are found as the best model as per in-sample statistical performance results, whereas according to out-of-sample, GARCH model is the best model with transaction costs. Moreover, Both the ARMA and AR models are nominated as the best model as per in-sample statistical performance results, whereas according to out-of-sample, the TARCH model is nominated as the best model without transaction costs. The EGARCH and TARCH models outperform all the other models as per to in-sample and out-of-sample trading performance outcomes respectively including transaction costs.
Enhanced SO<sub>2</sub> abatement with water‐hydrated dolomitic particles (1997)

Abstract A dolomitic calcine was hydrated with liquid water and then recalcined as an effective sorbent toward SO 2 removal. The hydrated/recalcined sorbent was tested for SO 2 removal in a thermogravimetric analyzer under conditions applicable to an atmospheric fluidized‐bed combustor: 1,123 K, 20 vol. % excess air, and 3,000 ppmv SO 2 . Specific pore surface areas and volumes of hydrated/recalcined dolomites, hydrated at 80°C for 1 h, increased by four and five times, respectively, compared to unhydrated dolomitic calcines. Due to these improved pore characteristics, the SO 2 capture achieved by the hydrated/recalcined calcine, was 1.3–1.6 times higher than that of the unhydrated one after a 1‐h exposure to SO 2 concentrations of 0.11–0.31 vol. % at 1,073–1,173 K. In the hydrated/recalcined calcine CaO utilization was enhanced due to the absence of significant pore diffusional limitations, at least during the early reaction times, evidenced by the high apparent activation energy of 198 kJ/mol. On the contrary, the lower CaO utilization in the unhydrated calcine was presumably due to severe pore diffusional limitations, which dropped the apparent activation energy from 149 to 85 kJ/mol at > 1,123 K.
Robots asking for directions: the willingness of passers-by to support robots (2010)

This paper reports about a human-robot interaction field trial conducted with the autonomous mobile robot ACE (Autonomous City Explorer) in a public place, where the ACE robot needs the support of human passers-by to find its way to a target location. Since the robot does not possess any prior map knowledge or GPS support, it has to acquire missing information through interaction with humans. The robot thus has to initiate communication by asking for the way, and retrieves information from passers-by showing the way by gestures (pointing) and marking goal positions on a still image on the touch screen of the robot. The aims of the field trial where threefold: (1) Investigating the aptitude of the navigation architecture, (2) Evaluating the intuitiveness of the interaction concept for the passers-by, (3) Assessing people's willingness to support the ACE robot in its task, i.e. assessing the social acceptability. The field trial demonstrates that the architecture enables successful autonomous path finding without any prior map knowledge just by route directions given by passers-by. An additional street survey and observational data moreover attests the intuitiveness of the interaction paradigm and the high acceptability of the ACE robot in the public place.
Synthesis and structure-activity relationships of 2',3'-dideoxypurine nucleosides as potential antiretroviral agents. (1991)

In order to study the structure-activity relationships of 2',3'-dideoxypurine nucleosides as potential anti-retroviral agents, various purine derivatives have been synthesized and tested against rous sarcoma virus (RSV) in chick embryo fibroblast (CEF) cells, and against human immunodeficiency virus (HIV) in human CD4+ T cells (ATH8). Some of the new purine derivatives found to be significant antiretroviral activities. And the correlations of activity between anti-RSV and anti-HIV have shown fairly good values so far.
A common-path optical coherence tomography based electrode for structural imaging of nerves and recording of action potentials (2013)

Current technologies for monitoring neural activity either use different variety of electrodes (electrical recording) or require contrast agents introduced exogenously or through genetic modification (optical imaging). Here we demonstrate an optical method for non-contact and contrast agent free detection of nerve activity using phase-resolved optical coherence tomography (pr-OCT). A common-path variation of the pr-OCT is recently implemented and the developed system demonstrated the capability to detect rapid transient structural changes that accompany neural spike propagation. No averaging over multiple trials was required, indicating its capability of single-shot detection of individual impulses from functionally stimulated <i>Limulus</i> optic nerve. The strength of this OCT-based optical electrode is that it is a contactless method and does not require any exogenous contrast agent. With further improvements in accuracy and sensitivity, this optical electrode will play a complementary role to the existing recording technologies in future.

Synthetic speech detection using temporal modulation feature (2013)

Voice conversion and speaker adaptation techniques present a threat to current state-of-the-art speaker verification systems. To prevent such spoofing attack and enhance the security of speaker verification systems, the development of anti-spoofing techniques to distinguish synthetic and human speech is necessary. In this study, we continue the quest to discriminate synthetic and human speech. Motivated by the facts that current analysis-synthesis techniques operate on frame level and make the frame-by-frame independence assumption, we proposed to adopt magnitude/phase modulation features to detect synthetic speech from human speech. Modulation features derived from magnitude/phase spectrum carry long-term temporal information of speech, and may be able to detect temporal artifacts caused by the frame-by-frame processing in the synthesis of speech signal. From our synthetic speech detection results, the modulation features provide complementary information to magnitude/phase features. The best detection performance is obtained by fusing phase modulation features and phase features, yielding an equal error rate of 0.89%, which is significantly lower than the 1.25% of phase features and 10.98% of MFCC features.
PRINTING MEMS: FROM A SINGLE FLEXIBLE POLYMIDE FILM TO THREE-DIMENSIONAL INTEGRATED MICROFLUIDICS (2008)

With the major advances in soft lithography and polymeric materials, use of microfluidic lab-on-a-chip device has attracted tremendous attention recently.A simple and fast micromachining process is highly in demand to prototype such a device.In this paper, we first reported an out-of-cleanroom printing-based integrated microfabrication process, referred to as printing microelectromechanical system (Printing MEMS).Using the Printing MEMS process, we demonstrated the potential to accomplish an entire design-to-fabrication cycle within an hour, including 50 μm-resolution non-lithographic patterning, wellcontrolled polyimide etching, three-dimensional pattern alignment and multilayer wax fusion bonding.A microfluidic mixer was prepared by this method and tested for the process validation.
Youth StreetConnect - Helping homeless young women (2014)

An estimated 2.5 million youth, ages 16-24, experience homelessness in the US each year. These young individuals, particularly women, are considered high-risk for serious health problems, including HIV, STDs, teen pregnancy and teen dating violence. Healthcare providers can play a critical role in providing appropriate care to homeless youth and in linking them to other health services. Research suggests that linking healthcare with other services needed by homeless adolescents, such as shelter or food, may help improve their continuity of care. In this paper, we describe Youth StreetConnect, a tool formed by two mobile apps, which will connect young homeless women to local healthcare providers. Considering that cellular phones are common among homeless individuals, particularly teenagers, our tool has the potential to make an impact on these women's lives.

One-dimensional CdS nanostructures: synthesis, properties, and applications (2010)

One-dimensional (1D) semiconductor nanostructures are of prime interest due to their potential in investigating the size and dimensionality dependence of the materials' physical properties and constructing nanoscale electronic and optoelectronic devices. Cadmium sulfide (CdS) is an important semiconductor compound of the II-VI group, and its synthesis and properties have been of growing interest owing to prominent applications in several fields. This article provides a comprehensive review of the state-of-the-art research activities that focus on the rational synthesis, novel properties and unique applications of 1D CdS nanostructures in nanotechnology. It begins with the rational design and synthesis of 1D CdS nanostructures, and then highlights a range of unique properties and applications (e.g. photoluminescence, cathodoluminescence, electrochemiluminescence, photocatalysis, lasers, waveguides, modulators, solar cells, field-effect transistors, photodetectors, field-emitters, and nanogenerators) associated with them. Finally, the review is concluded with the author outlook of the perspectives with respect to future research on 1D CdS nanostructures.
Mutagenesis of the <i>supF</i> Gene of pSP189 Replicating in AD293 Cells Cocultivated with Activated Macrophages:  Roles of Nitric Oxide and Reactive Oxygen Species (2006)

Dysregulated production of nitric oxide (NO*) and reactive oxygen species by inflammatory cells contributes to mutagenesis and carcinogenesis. We have characterized mutagenesis in the target supF gene of pSP189 replicating in AD293 cells cocultivated with mouse macrophage-like RAW264.7 cells activated with interferon-gamma (IFN-gamma) and lipopolysaccharide (LPS). Activated macrophages produced substantial amounts of NO*, superoxide anion (O2*-), and hydrogen peroxide (H2O2) over 12-72 h periods. A time-dependent decrease in total cell number and a 3.7-fold increase in supF mutation frequency (MF), compared with unstimulated controls, were observed at 72 h. The increase in MF was effectively suppressed by N-methyl-L-arginine monoacetate (NMA), an NO* synthase inhibitor, and also by superoxide dismutase (SOD) and catalase (CAT); cotreatment with NMA and SOD/CAT suppressed mutagenesis by 87% at 72 h. Mutations in supF were mainly multiple sequence changes (47%) and single base pair substitutions (51%) following IFN-gammaLPS activation. Following cotreatment with NMA alone or together with SOD/CAT, however, single base pair substitutions were prevalent (70 and 85%); decreased multiple mutations were observed (24 and 11%). Almost all single base pair substitutions induced under all exposure conditions occurred at G:C base pairs (87.8-94.6%). Whereas those induced by all treatments consisted predominantly of G:C to T:A transversions, G:C to T:A and A:T to T:A transversions were less frequent following treatment with NMA alone or with SOD/CAT compared to those induced by activated macrophages without additional treatment. Our results strongly suggest that ONOO- or its derivatives generated by reaction of NO* with O2*- may have been a major contributor to the observed mutagenesis by the activated macrophages, and mitigating their effects might serve a preventive function in ameliorating cancer risks associated with prolonged inflammation.
Overexpression, Purification, and Characterization of Escherichia coli Acyl Carrier Protein and 2 Mutant Proteins (1995)

A synthetic gene of 237 bases encoding the 77-residue acyl carrier protein (ACP) from Escherichia coli, along with two mutant genes, ACP-I54V and ACP-A59V, were subcloned into the pET11a-pLysS E. coli overexpression system under the control of the bacteriophage T7 promoter, This efficient expression system and a simplified purification protocol yielded more than 120 mg/l of pure protein. The construct produced a mixture of holo-ACP and apo-ACP and two HPLC procedures were developed to separate the two species, This overexpression system allows cost-effective growths of 13C- and 15N-labeled protein for structural and other studies on ACP. In the course of the work on the mutants of ACP, an apparent homologous recombination event led, in one case, to reversion to a wild-type protein, suggesting that precautions to prevent such reversion should be taken.
Bandwidth enhancement in disordered metamaterial absorbers (2014)

In this letter, we show numerically and experimentally that a positional disorder of a collection of absorbing electromagnetic wave resonators operating in the long wavelength regime dramatically enhances the absorption bandwidth. The demonstration is performed by using single-size ring-shaped thin metal pieces periodically or randomly positioned onto a back-grounded dielectric layer. For periodic array, an optimum in the periodicity is pointed out with a narrow bandwidth, while the increasing influence of coupling effects for resonators in close vicinity explains a three-fold bandwidth enhancement in the case of positional disorder.

Cosmic ray neutron induced upsets as a major contributor to the soft error rate of current and future generation DRAMs (1996)

The system soft error rate (SSER) of 4M/16M DRAMs has been shown to be dependent on the cosmic ray neutron flux. A simple model and accelerated soft error rate (ASER) measurements made with an intense, high energy neutron beam support this result. The model predicts that cosmic ray neutron induced soft errors will become important at the 64M DRAM generation and beyond.

Efficient dye-sensitized solar cells based on a 2-thiophen-2-yl-vinyl-conjugated ruthenium photosensitizer and a conjugated polymer hole conductor (2006)

Efficient dye-sensitized TiO2 solar cells based on a 2-thiophen-2-yl-vinyl-conjugated ruthenium photosensitizer and a conjugated polymer poly(3,4-ethylenedioxythiophene) have been fabricated. A maximum power conversion efficiency of 2.6% is achieved when the mesoporous TiO2 layer is 5–6μm. The high fill factor (0.74), the open circuit voltage (0.78V), and the linear light intensity dependence of the short circuit current density (4.5mAcm−2 at 100mWcm−2) make these devices promising for solid state photovoltaic applications.
