Design and analysis of BWB military cargo centre body structure (2009)

A columned multi-bubble fuselage is proposed for a blended wing body ultra heavy lifter. Inter-cabin walls of conventional multi bubble fuselage were replaced with columns to provide a large and contiguous area. The configuration allows the membrane stresses of the round wing panels to be balanced with the tensile stresses in the columns. CMBF was analyzed and compared with a conventional MBF to verify its structural performance and integrity regarding weight reduction and stiffness. Initial analysis shows that the CMBF has a significant weight advantage over conventional MBF. The paper introduces the objectives of the project and presents preliminary structural design and analysis results.
Quantum computing with itinerant microwave photons (2013)

Microwave photons in superconducting circuits is a promising approach for quantum computing due to long coherence times and the easy controllability of superconducting devices. However, as the search of the ultimate design of a quantum computer is still ongoing, various suggestions for the realization of a quantum bit, qubit, exist even in the area of superconducting circuits.\nIn this thesis, we study theoretically quantum computing using itinerant microwave photons as qubits. Basic tools for treating the reflection of wave packets and the noise generated by resistive elements in a circuit are derived starting from a widely used model for superconducting transmission lines. We also present simple quantum devices that can act as quantum gates for microwave qubits, including a novel suggestion for a tunable phase shifter. A tunable phase shifter is a useful component in the study of microwave photons in general as well as in quantum computing. The tunable phase shifter consists of three superconducting quantum interference devices (SQUIDs) that can be treated as tunable inductors in the low-power regime.\nThe results of this thesis can be used both in applications related to quantum computing and in the general study of quantum mechanics in circuits. In particular, we conclude that there exist feasible system parameters, for which it should be possible to demonstrate the tunable phase shifter utilizing available experimental techniques. We also show the principle how the possible nonlinearity of the phase shifter can be used in a two-qubit gate providing interactions between microwave photons.
Preparation of new nitrogen-bridged heterocycles. XIII Syntheses of some tricyclic and tetracyclic indolizine derivatives with antiallergic activity. (1986)

Alkaline treatment of 2, 3-annelated 1-ethoxycarbonylmethylpyridinium bromides was investigated as a method for the preparation of 1, 8-annelated indolizine derivatives. The reaction of 1-ethoxycarbonylmethyl-2, 3-cyclopentenopyridinium bromide (1) with ethanolic sodium ethoxide did not afford any significant products, but similar treatment of 1-ethoxycarbonylmethyl-2, 3-cyclohexenopyridinium bromide (8) gave the expected 1, 8-annelated 2(3H)-indolizinone, 8, 9-dihydro-7H-pyrrolo[3, 2, 1-ij]quinolin-1(2H)-one (9), in 53% yield. The reactions of the salt 8 with a base in the presence of some vinylating and alkylating or acylating agents afforded the corresponding 1-alkoxy- or 1-acyloxy-2-vinylpyrroloquinoline derivatives (26-35), which were further transformed to tetracyclic indolizines fused with a furan or a puran ring. Some of these tricyclic and tetracyclic indolizines showed antiallergic activity.

Made to measure: new materials for the 21st century (1998)

This text describes how scientists are inventing thousands of materials, ranging from synthetic skin, blood and bone, to substances that repair themselves and adapt to their environment, that swell and flex like muscles, that repel any ink and paint, and that capture and store the energy from the Sun. It shows that this is being accomplished because materials are being designed for particular applications, rather than being discovered in nature or by haphazard experimentation. Linking insights from chemistry, biology and physics, with those from engineering, the book outlines the various areas in which newly-invented materials will transform our lives in the 21st century. The chapters provide vignettes from a broad range of selected areas of materials science and can be read as separate essays. The subjects include: photonic materials; materials for information storage; smart materials; biomaterials; biomedical materials; materials for clean energy; porous materials; diamond and hard materials; polymers; and surfaces and interfaces.
DNA Fingerprinting Validates Seed Dispersal Curves from Observational Studies in the Neotropical Legume Parkia (2012)

Our study showed that seed dispersal distances can be reliably estimated through observational methods when a strict criterion for inclusion of seeds is observed. Furthermore, dispersal distances produced by the two primate species indicated that these primates fulfil one of the criteria for efficient seed dispersers. Finally, our study demonstrated that DNA extraction methods so far employed for temperate plant species can be successfully used for hard-seeded tropical plants.
Natural language processing in cross-media analysis (2018)

A cross-media analysis framework is an integrated multi-modal platform where a media resource containing different types of data such as text, images, audio and video is analyzed with metadata extractors, working jointly to contextualize the media resource. It generally provides cross-media analysis and automatic annotation, metadata publication and storage, searches and recommendation services. For on-line content providers, such services allow them to semantically enhance a media resource with the extracted metadata representing the hidden meanings and make it more efficiently searchable. Within the architecture of such frameworks, Natural Language Processing (NLP) infrastructures cover a substantial part. The NLP infrastructures include text analysis components such as a parser, named entity extraction and linking, sentiment analysis and automatic speech recognition. Since NLP tools and techniques are originally designed to operate in isolation, integrating them in cross-media frameworks and analyzing textual data extracted from multimedia sources is very challenging. Especially, the text extracted from audio-visual content lack linguistic features that potentially provide important clues for text analysis components. Thus, there is a need to develop various techniques to meet the requirements and design principles of the frameworks. In our thesis, we explore developing various methods and models satisfying text and speech analysis requirements posed by cross-media analysis frameworks. The developed methods allow the frameworks to extract linguistic knowledge of various types and predict various information such as sentiment and competence. We also attempt to enhance the multilingualism of the frameworks by designing an analysis pipeline that includes speech recognition, transliteration and named entity recognition for Amharic, that also enables the accessibility of Amharic contents on the web more efficiently. The method can potentially be extended to support other under-resourced languages.Â
Site-granularity topic distillation on the Web by combining content and hyperlink analysis (2004)

Topic distillation on the Web, namely, given a user query to find quality information sources related to the query topic by using hyperlink analysis, has been shown to be useful in Web IR. Based on the analysis of three deficiencies of classical topic distillation algorithm HITS (i.e., failing to meet users' site-granularity information needs; tending to produce unreasonable results; topic drift), this paper presents an improved model and algorithm named s-HITSc (site-granularity HITS enhanced by content analysis). Given a query topic, the new algorithm can model a neighborhood graph at site granularity, compute the relevance weights of the nodes to the topic with content analysis, and apply weighted I/O operations in its iterative hyperlink analysis. Theoretical analysis and experimental results show that the new algorithm can control topic drift and identify more reasonable and meaningful authority and hub sites on a given query topic.
[Afobasol antifibrillation activity in animals with the intact and denervated myocardium]. (2010)

The influence of afobasol on threshold electrical fibrillation of the heart was studied in experiments on narcotized cats. It significantly elevated the cardiac fibrillation threshold in animals with intact myocardium and resembled class 1B anti-arrhythmic drug lidocaine in terms of this activity. Similar results were obtained using cats with denervated myocardium. These observations indicate that in the model of electrical fibrillation of the heart afobasol has marked antifibrillation action mediated through cardiomyocytes. This inference was confirmed by the studies of afobasol effects on cardiac rhythm variability in rats with acute myocardial ischemia. It is supposed that afobasol prevents cardiac fibrillation acting as an agonist of cytosolic sigma-1 receptors in cardiomyocytes
The unstable urethra in the female. (1989)

The clinical and urodynamic characteristics of 54 women with unstable urethras (falls of urethral pressures of at least 20 cm H2O) were compared with those of 171 patients with stable urethras. The unstable-urethra patients were younger and presented with an increased incidence of marked urgency and a lower incidence of genuine stress incontinence. The average urethral pressure fall was preceded by a 6-cm increase in maximum urethral pressure. The mean (+/- SD) fall of urethral pressure was 30 +/- 12 cm H2O and the average duration of the event was 8 seconds. The level of the urethral pressure fall was not influenced by bladder volume but correlated positively with higher maximum urethral pressures. The present findings suggest that the unstable urethra plays a limited role in genuine stress incontinence but may be linked with the unstable detrusor.

MobileBERT: a Compact Task-Agnostic BERT for Resource-Limited Devices (2020)

Natural Language Processing (NLP) has recently achieved great success by using huge pre-trained models with hundreds of millions of parameters. However, these models suffer from heavy model sizes and high latency such that they cannot be deployed to resource-limited mobile devices. In this paper, we propose MobileBERT for compressing and accelerating the popular BERT model. Like the original BERT, MobileBERT is task-agnostic, that is, it can be generically applied to various downstream NLP tasks via simple fine-tuning. Basically, MobileBERT is a thin version of BERT_LARGE, while equipped with bottleneck structures and a carefully designed balance between self-attentions and feed-forward networks. To train MobileBERT, we first train a specially designed teacher model, an inverted-bottleneck incorporated BERT_LARGE model. Then, we conduct knowledge transfer from this teacher to MobileBERT. Empirical studies show that MobileBERT is 4.3x smaller and 5.5x faster than BERT_BASE while achieving competitive results on well-known benchmarks. On the natural language inference tasks of GLUE, MobileBERT achieves a GLUEscore o 77.7 (0.6 lower than BERT_BASE), and 62 ms latency on a Pixel 4 phone. On the SQuAD v1.1/v2.0 question answering task, MobileBERT achieves a dev F1 score of 90.0/79.2 (1.5/2.1 higher than BERT_BASE).
Upsampling Technique in Multi-Resolution Texture Mapping for Real-Time Terrain Rendering (2008)

In the traditional multi-resolution texture mapping method for large-scale terrain rendering, the resolution of the terrain texture is only decided by the distance to the viewpoint. In some sharp region texture is stretched a lot and brings the mapping distortion problems, which affect the visual effect of virtual scene. In order to solve this problem, many methods were proposed. The most universal method is to gain the texture with higher resolution and map it onto the sharp regions. But texture in the finest resolution level has no higher resolution texture available. By analyzing the nature attribute of terrain slope, we propose an efficient upsampling method with adaptive resolution based on the terrain slope measure and apply it successfully in our real time terrain navigating system. Experimental result shows that our adaptive method finely enhances the reality of the virtual scene in the premise of tiny affecting the rendering speed.

Endovascular problem solving with intravascular stents. (2000)

Stents can be used to provide stabilization of irretrievable intravascular devices or as a scaffolding for proximal vessel sacrifice. These applications may allow endovascular rescue of procedural complications and solve unique clinical problems.
Achromatic phase retarders constructed from right-angle prisms: design (1984)

The behavior of achromatic 90 and 180° phase retarder devices has been computed. These devices are made of three right-angle prisms so that the transmitted beam is not deflected or deviated from its incoming direction although the beam has suffered four internal reflections. Conventional BK-7 prisms and quartz prisms can be used as achromatic 180 and 90° phase retarders if suitable dielectric coatings are applied to the reflecting surfaces. With other glass types extremely achromatic 180° retarders can be obtained with <0.2% deviation from 180° throughout the visible wavelength range. This is five times better than the so-called superachromatic retarders made of several birefringent plates of different materials.
Klinische Erfahrungen mit der Ultraschall-Reflexions-Computertomographie der Brust (1987)

Ultrasound-reflection computed tomography (URCT) of the breast can produce astonishingly detailed high resolution images of the breast, particularly in the coronal plane. In some cases it improves the demonstration of the structure of scirrhous carcinomas in this plane. On the other hand, some valuable diagnostic features known from conventional breast sonography, such as acoustic shadows and hyper-reflective area (cysts) are suppressed on URCT images and are not readily recognized. Despite individual outstanding images, a comparison carried out on 100 patients showed no advantages of URCT compared with high-resolution real-time sonography.
Collagenous Colitis (1987)

Two hypotheses have been proposed to explain the pathogenesis and cause of the increased subepithelial collagen deposition that occurs in patients with collagenous colitis, a rare disease of unknown cause. One hypothesis considers an inflammatory origin, and the other, a local abnormality of collagen synthesis. An analysis of clinical, endoscopic, and histologic findings from one of our patients and from previously published cases suggests that collagenous colitis is a form of inflammatory bowel disease characterized by localization of the initial injury to the superficial subepithelial zone and with subsequent fibrosis in that area. The data show a spectrum of clinical and histologic changes that represent different stages in the evolution of the inflammatory process.
Curcumin (diferuloylmethane) induces apoptosis and blocks migration of human medulloblastoma cells. (2010)

Medulloblastoma (MB) is the most common malignant brain tumor in children. Bcl-2 and MMP-9 promote the pathogenesis and progression of MB. The expression of both bcl-2 and MMP-9 is regulated by the transcription factor NF-kappaB. Curcumin, a natural food additive, has a potent anti-proliferative effect, presumably mediated through NF-kappaB suppression. The tumor-suppressing effects of curcumin are well documented, however, its effect on MB is unknown. Our objectives were to: a) examine the effect of curcumin on MB cell proliferation and apoptosis; b) characterize the mechanism that mediates the effect of curcumin; c) examine the effects of curcumin on MB cell migration. We report that curcumin inhibited cell proliferation and blocked clonogenicity of MB cells. Furthermore, curcumin down-regulated bcl-2 and bcl(x)l, leading to caspase-mediated cell death. Finally, curcumin blocked migration of MB cells. Thus, we propose developing curcumin as a novel therapeutic agent for MB.
Physiological Mg<sup>2+</sup> Conditions Significantly Alter the Inhibition of HIV-1 and HIV-2 Reverse Transcriptases by Nucleoside and Non-Nucleoside Inhibitors <i>in Vitro</i> (2016)

Reverse transcriptases (RTs) are typically assayed in vitro with 5-10 mM Mg<sup>2+</sup>, whereas the free Mg<sup>2+</sup> concentration in cells is much lower. Artificially high Mg<sup>2+</sup> concentrations used in vitro can misrepresent different properties of human immunodeficiency virus (HIV) RT, including fidelity, catalysis, pausing, and RNase H activity. Here, we analyzed nucleoside (NRTIs) and non-nucleoside RT inhibitors (NNRTIs) in primer extension assays at different concentrations of free Mg<sup>2+</sup>. At low concentrations of Mg<sup>2+</sup>, NRTIs and dideoxynucleotides (AZTTP, ddCTP, ddGTP, and 3TCTP) inhibited HIV-1 and HIV-2 RT synthesis less efficiently than they did with large amounts of Mg<sup>2+</sup>, whereas inhibition by the "translocation-defective RT inhibitor" EFdA (4'-ethynyl-2-fluoro-2'-deoxyadenosine) was unaffected by Mg<sup>2+</sup> concentrations. Steady-state kinetic analyses revealed that the reduced level of inhibition at low Mg<sup>2+</sup> concentrations resulted from a 3-9-fold (depending on the particular nucleotide and inhibitor) less efficient incorporation (based on k<sub>cat</sub>/K<sub>m</sub>) of these NRTIs under this condition compared to incorporation of natural dNTPs. In contrast, EFdATP was incorporated with an efficiency similar to that of its analogue dATP at low Mg<sup>2+</sup> concentrations. Unlike NRTIs, NNRTIs (nevirapine, efavirenz, and rilviripine), were approximately 4-fold (based on IC<sub>50</sub> values) more effective at low than at high Mg<sup>2+</sup> concentrations. Drug-resistant HIV-1 RT mutants also displayed the Mg<sup>2+</sup>-dependent difference in susceptibility to NRTIs and NNRTIs. In summary, analyzing the efficiency of inhibitors under more physiologically relevant low-Mg<sup>2+</sup> conditions yielded results dramatically different from those from measurements using commonly employed high-Mg<sup>2+</sup> in vitro conditions. These results also emphasize differences in Mg<sup>2+</sup> sensitivity between the translocation inhibitor EFdATP and other NRTIs.
Multiobjective Optimization Analysis of a Recycling Based Regional Production System (2000)

In this paper, we will simulate a recycling based regional production system taking account of pollutants and discarded parts of new products. Decision made there can help us to develop a plan to produce new environmentally conscious products under marketing strategy about the products. We investigate and construct an analytical model for the recycling based regional system. This model is formulated as a multiobjective liner programming problem. We consider three objectives; such as to decrease the total cost, to increase the part-recycling, and the material-recycling. We apply the ε-constrained method and the weighting objectives method respectively to obtain and observe the Pareto optimal solution and preferred solution for confirming the effectiveness of the proposed model.
Improving User's Web Search Experience by Interactive Re-ranking and Zooming Interfaces (2009)

AbstrAct: The well-known search engines such as Google, Yahoo! and MSN, are not enough for the advanced users who require user experience, for instance, much more correlative words, or interactive operations applied to returned results such as re-ranking and zooming. To focus on this idea of interactivity, we proposed and implemented interactive interfaces to improve user experience for supporting Web search. They are nice interfaces supporting dynamically changing re-ranking, related word zooming, and related word emphasizing and deemphasizing. It has been served as online search service recently. Our experimental evaluations confirm their convenience and good online performance.

Cleaning frequency optimization for soiled photovoltaic modules (2015)

This study was conducted to determine the optimum cleaning frequency for cleaning Photovoltaic (PV) modules installed in Mesa (near Phoenix), Arizona, United States. By monitoring the soiling loss of PV modules mounted on a mock rooftop at ASU-PRL during May through June 2014 (highest soiling period for this site), a detailed soiling loss modeling was obtained. During the dry/soiling summer season, the daily soiling rate has been determined to be -0.061% for 20° tilted PV modules. Based on the monitored soiling rate and extensive simulation of this investigation, it is concluded that the cleaning is not economically justifiable for 20° or higher tilted residential PV modules of this and nearby sites.
