Aluminum Oxide (Alumina), Calcined, Tabular, and Aluminate Cements (2003)

Abstract Calcined aluminas are generally obtained from Bayer process gibbsite α ‐Al(OH) 3 , thermal decomposition of which follows the transition through the generic gamma alumina phases to α ‐alumina (corundum), α ‐Al 2 O 3 . Calcination of gibbsite has been done in rotary kilns for many years. Specialty calcined aluminas can also be prepared in stationary or fluid bed calciners. Most ceramic grade aluminas are supplied dry ground to about 95% \documentclass{article}\pagestyle{empty}\begin{document}${{\rm{-}}325{\hskip0.167em}{\hskip0.167em}{\rm{mesh}}}$\end{document} (44 µ m) using 85–90% Al 2 O 3 ceramic ball, attrition, vibro‐energy, or fluid‐energy milling. More fully ground, or superground, calcined aluminas having particle size distributions that approximate the natural or ultimate crystal size of the Bayer grain as calcined are often desired. Thermally reactive aluminas contain submicrometer crystals. These must be separated from the Bayer agglomerate during grinding to permit dense compaction upon ceramic forming, and thus, enhance densification upon sintering at lower temperatures. Process control techniques permit production of calcined specialty aluminas having controlled median particle sizes differentiated by about 0.5 µ m. This broad selection enables closer shrinkage control of high tech ceramic parts. Tabular alumina is a high density, high strength form of α ‐Al 2 O 3 made by sintering an agglomerated shape of ground, calcined alumina. It is available in the form of smooth balls which are crushed, screened, and ground to obtain a wide variety of graded, granular, and powdered products. Tabular alumina is the ideal base material for high alumina brick, and monolith liners in the metal, ceramic, and petrochemical industries. Other applications include their use in electrical insulators, electronic components, and kiln furniture. High purity calcium aluminate cements (CAC) are primarily used as binders for high strength refractory castables to form linings up to about 1.0 m thick, as in iron blast furnaces. The high purity CAC finds extensive use as an efficient binder for other aggregates such as fire clays, kaolin, andalusite, kyanite, pyrophyllite, sillimanite, mullite, and refractory‐grade bauxite. The many applications cited for tabular alumina in refractories are also common for high purity CAC.
Characterization of type 1 and type 2 cytokine production profile in physiologic and pathologic human pregnancy (1996)

Antigen- and mitogen-stimulated cytokine production by peripheral blood mononuclear cells (PBMC) of 50 pregnant women and 31 age- and sex-matched non-pregnant controls were analysed to determine whether changes in cytokine production occur during normal and pathologic human gestation. The pregnant women, consecutively enrolled during a 3-month period, were undergoing a normal, non-pathologic pregnancy at the time of entry into the study, and underwent ultrasound examination to ascertain the exact week of pregnancy and the vitality of the fetus. Forty of the 50 pregnancies (80%) terminated physiologically with the birth of normal babies. Spontaneous abortions were observed in 5/50 (10%) women, and five women gave birth to newborns small for gestational age (SGA). A decrease in the production of IL-2 and interferon-gamma (IFN-gamma) accompanied by an increase in production of IL-4 and IL-10, was observed in normal pregnancy, with the lowest quantities of IL-2 and IFN-gamma and the highest quantities of IL-4 and IL-10 present in the third trimester of pregnancy. Statistically significant increased production of both IL-2 and IFN-gamma and reduced production of IL-10 characterized pathologic pregnancies and distinguished them from normal pregnancies. These preliminary data suggest that a type 2 cytokine profile may be associated with normal human pregnancy, whereas the lack of a dominant type 2 cytokine profile may be indicative of a pathologic pregnancy.
Direct Measurement of Correlation Between SRAM Noise Margin and Individual Cell Transistor Variability by Using Device Matrix Array (2011)

Noise margin, characteristics of six individual cell transistors, and their variability in static random-access memory (SRAM) cells are directly measured using a special device-matrix-array test element group of 16-kb SRAM cells, and the correlation between the SRAM noise margin and the cell transistor variability is analyzed. It is found that each cell shows a very different supply voltage <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$V_{dd}$</tex> </formula> dependence of the static noise margin (SNM), and this scattered <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX"> $V_{dd}$</tex></formula> dependence of the SNM is not explained by the measured threshold voltage <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$V_{\rm th}$</tex></formula> variability alone, indicating that the circuit simulation taking only the <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$V_{\rm th}$</tex></formula> variability into account will not predict the SRAM stability precisely at low supply voltage.
Read, write, and navigation awareness in realistic multi-view collaborations (2007)

Read, write, and navigation awareness allow users of a multi-view collaborative editor to get fine-grained information about whether others are reading what they are editing, where others are editing, and to which areas of the document others have navigated, respectively. We derive new high-level tools that directly support the three kinds of awareness. The results of a decision-making study involving the use of these tools revealed that write awareness helps with fine-grained conflict prevention, read awareness reduces unnecessary verbal communication, and navigation awareness is most effective when coupled with read and write awareness. Thus, the study identifies specific uses of the three forms of awareness and motivates tools for supporting them.
A novel concept for long-term pre-storage and release of liquids for pressure-driven lab-on-a-chip devices (2015)

On-chip storage of liquids is one of the major challenges of polymer-based lab-on-a-chip (LoC) devices. To ensure long-term storage of even highly volatile reagents in polymer disposal LoC cartridges, robust reagent storage concepts are necessary. Tubular bags, so-called stick packs, are widely used in the packaging industry. They offer sufficient vapor barrier properties for liquid storage. Here we present a polymer multilayer LoC-stack with integrated stick packs for the long-term storage of liquid reagents required for diagnostic applications. The storage concept fulfils two main requirements: firstly, the long-term storage of reagents in stick packs without significant losses or interaction with the surroundings and secondly, the on-demand release of liquids, which is realized by the delamination of a stick pack's peel seam through pneumatic pressure. Furthermore, effects on the opening behavior of stick packs through accelerated aging were investigated after different storage conditions to proof repeatability. This concept enables on-chip storage of liquid reagents at room temperature and allows the implementation in different pressure driven LoC devices or similar applications. Since liquid storage in stick packs is well-established, emerging fields such as lab-on-a-chip combined with novel reagent release mechanisms should be of great interest for the commercialization of life science products.
Predicting user intent from search queries using both CNNs and RNNs (2018)

Predicting user behaviour on a website is a difficult task, which requires the integration of multiple sources of information, such as geo-location, user profile or web surfing history. In this paper we tackle the problem of predicting the user intent, based on the queries that were used to access a certain webpage. We make no additional assumptions, such as domain detection, device used or location, and only use the word information embedded in the given query. In order to build competitive classifiers, we label a small fraction of the EDI query intent prediction dataset \cite{edi-challenge-dataset}, which is used as ground truth. Then, using various rule-based approaches, we automatically label the rest of the dataset, train the classifiers and evaluate the quality of the automatic labeling on the ground truth dataset. We used both recurrent and convolutional networks as the models, while representing the words in the query with multiple embedding methods.
Stealth prefetching (2006)

Prefetching in shared-memory multiprocessor systems is an increasingly difficult problem. As system designs grow to incorporate larger numbers of faster processors, memory latency and interconnect traffic increase. While aggressive prefetching techniques can mitigate the increasing memory latency, they can harm performance by wasting precious interconnect bandwidth and prematurely accessing shared data, causing state downgrades at remote nodes that force later upgrades.This paper investigates Stealth Prefetching, a new technique that utilizes information from Coarse-Grain Coherence Tracking (CGCT) for prefetching data aggressively, stealthily, and efficiently in a broadcast-based shared-memory multiprocessor system. Stealth Prefetching utilizes CGCT to identify regions of memory that are not shared by other processors, aggressively fetches these lines from DRAM in open-page mode, and moves them close to the processor in anticipation of future references. Our analysis with commercial, scientific, and multiprogrammed workloads show that Stealth Prefetching provides an average speedup of 20% over an aggressive baseline system with conventional prefetching.
In denial: Defending Australia as China looks south (2019)

Let's be honest: Australians have never had much time for our South Pacific neighbours. The island nations that lie to our north and north-east, stretching from Papua New Guinea and Solomon Islands to Vanuatu, Fiji and beyond, may be close to us geographically, but we have not found them especially interesting, important or profitable. With a few honourable exceptions, and tourism aside, Australians have been indifferent to our nearest neighbours' dramatic landscapes, their rich and diverse cultures, and their general welfare, and we have seen relatively few opportunities for trade. Only their strategic significance has attracted us: the islands scattered widely across the north of our continent are critical to our protection from armed attack.
Monumental Questions and How We Honor Them (2020)

We are in another moment where who and how we memorialize is being reconsidered in communities small and large. My colleague, Zachary Bray, and I proposed this symposium to the Kentucky Law Journal because the topic reflected our shared interests in the debate over memorials and which historical narrative should triumph in the public square. We arrive at the question from different intellectual paths, but the common concern is over when and how stakeholders can and will revise that narrative through the regulation of monuments. These revisions often come in the form of calls for, it not outright, removal outhouse materials that do not fit with the communities current or aspirant view of itself and its history.
The Carbon Cycle (2000)

Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the 'missing sink' for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature. It will be an invaluable resource for students and researchers working in the field.
Tat substrates open the portal (2014)

Aldridge et al. suggest how chloroplast proteins could induce assembly of the pore complex that transports them across the thylakoid membrane.

The twin-arginine translocase (Tat) complex transports folded proteins across the thylakoid membranes of chloroplasts and the plasma membrane of bacteria.
Shallow Networks for High-accuracy Road Object-detection (2017)

The ability to automatically detect other vehicles on the road is vital to the safety of partially-autonomous and fully-autonomous vehicles. Most of the high-accuracy techniques for this task are based on R-CNN or one of its faster variants. In the research community, much emphasis has been applied to using 3D vision or complex R-CNN variants to achieve higher accuracy. However, are there more straightforward modifications that could deliver higher accuracy? Yes. We show that increasing input image resolution (i.e. upsampling) offers up to 12 percentage-points higher accuracy compared to an off-the-shelf baseline. We also find situations where earlier/shallower layers of CNN provide higher accuracy than later/deeper layers. We further show that shallow models and upsampled images yield competitive accuracy. Our findings contrast with the current trend towards deeper and larger models to achieve high accuracy in domain specific detection tasks.
Organocatalytic Asymmetric Vinylogous Michael Reactions (2017)

Abstract Since R. C. Fuson formulated the principle of vinylogy, this platform has been extensively developed through combining diverse predominant chemical transformations. Among them, asymmetric vinylogous Michael reaction has been recognized as an efficient method to build chiral 1,7‐dioxo C chains (1,9‐dioxo C chains for bisvinylogous manifold) with diverse functional groups, which provides robust approaches to access numerous chiral compounds with pharmaceutical importance. In this review, the advances in the area of organocatalytic asymmetric vinylogous Michael reactions on the period from 2014 to nowadays are discussed, including the current scope, limitations of the transformations and applications in asymmetric synthesis of complex and valuable compounds.

Summary form only given. We report on recent time-resolved photoluminescence (PL) measurements of CdSe-ZnSe self-assembled quantum dots. In order to visualize single dots, we take time-resolved spectra through 200-nm apertures defined through a metal film on the surface of the sample.
The α-Hemolysin nanopore transduction detector – single-molecule binding studies and immunological screening of antibodies and aptamers (2007)

It may be possible to directly track the bound versus unbound state of a huge variety of molecules using nanopore transduction detection.
Detecting Ellipses via Bounding Boxes (2006)

A novel algorithm for ellipse detection based on bounding boxes is proposed in this paper. The bounding box is used in many different contexts in computer graphics as a complexity limiting device. For a perfect ellipse, the bounding box can be located by scanning an image and the corresponding geometric features can then be derived. The concept of bounding box is similar to that of the geometric symmetry approach. Instead of finding edges, we utilize a preprocessed binary image as the input to our algorithm. The search space of parameters is also condensed to a small area. Simulation results show the effectiveness of our approach.
Redistribution of muscarinic acetylcholine receptors on human fibroblasts induced by regulatory ligands (1987)

Distribution of the muscarinic acetylcholine receptor on human fibroblasts was determined by immunofluorescence and immunoperoxidase staining using the anti-muscarinic receptor antibody M-35b. The receptor appeared to be randomly distributed on the cell surface in 1- or 2-day nonconfluent cultures. Brief exposure to 0.1 mM carbamylcholine (15 min to 1 hr) induced receptor accumulation in several restricted domains of the cell surface. This process was associated with sequestration into uncoated vesicles. Random receptor distribution was restored by incubation in ligand-free medium for 4 hr after carbamylcholine treatment, and vesicular profiles were no longer detectable. When incubation with the agonist was prolonged (3 hr at 37 degrees C), endocytotic 'smooth vesicles' fused and formed multivesicular structures presumably implicated in receptor down-regulation. Conversely, when nonconfluent cells were exposed to the muscarinic antagonist atropine, receptor redistribution was revealed, leading to the formation of clusters where receptor accumulated. Muscarinic receptor redistribution induced by atropine therefore does not involve the sequestration process seen in carbamylcholine-treated cells.
Packet video and its integration into the network architecture (1989)

Packet video is investigated from a systems point of view. The most important issues relating to its transmission are identified and studied in the context of a layered network architecture model, leading to a better understanding of the interactions between network and signal handling. The functions at a particular layer can thereby be made less dependent on network implementation and signal format. In the layered network model, the higher layers provide format conversion, hierarchical source coding, error recovery, resynchronization, cost/quality arbitration, session setup and tear-down, packetization, and multiplexing. Provisions from the network layers pertain mainly to real-time transmission. Special consideration is given to hierarchical source coding, error recovery, statistical behavior, and timing aspects. Simulation results indicating practical solutions to some of the issues raised are presented for a hierarchical packet-video subband coding system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A resilient structure as a survival strategy for Japan’s chemical industry amidst megacompetition (2007)

Japan’s chemical industry is currently amidst mega‐competition in the paradigm shift from an industrial society to an information society that emerged in the 1990s and consequent globalizing economy. The checkered development trajectory of Japan’s chemical industry has resulted in a fragile structure with increasing geographical constraints and excessive competition in certain markets among a number of small‐scale firms. A simultaneous solution to divergent activities for diversified customer requirements as well as dynamically changing external circumstances and convergence for improving competitiveness in core competent fields is thus essential. This paper attempts to identify an optimal trajectory for Japan’s chemical industry by providing a simultaneous solution to the above contradicting demands. A resilient structure that incorporates an optimal level of diversification based on a specific reinforced core competent field is postulated as a survival strategy in a business environment characterized by mega‐competition. Aiming at demonstrating the significance of a resilience structure, an empirical analysis focusing on Japan’s 28 leading chemical firms was conducted. An optimal level of technological diversification for Japan’s chemical industry firms was thereby identified, thus leading to construction of a resilient structure.
Structural analysis of the varicella-zoster virus gp98-gp62 complex: posttranslational addition of N-linked and O-linked oligosaccharide moieties (1985)

Varicella-zoster virus specifies the formation of several glycoproteins, including the preponderant gp98-gp62 glycoprotein complex in the outer membranes of virus-infected cells. These viral glycoproteins are recognized and precipitated by a previously described monoclonal antibody designated monoclone 3B3. When an immunoblot analysis was performed, only gp98 was reactive with monoclone 3B3 antibody; likewise, titration in the presence of increased concentrations of sodium dodecyl sulfate during antigen-antibody incubations caused selective precipitation of gp98 but not gp62. Further structural analyses of gp98 were performed by using the glycosidases endo-beta-N-acetylglucosaminidase H (endoglycosidase H) and neuraminidase and two inhibitors of glycosylation (tunicamycin and monensin). In addition to gp98, antibody 3B3 reacted with several intermediate products, including gp90, gp88, gp81, and a nonglycosylated polypeptide, p73. Since gp98 was completely resistant to digestion with endoglycosidase H, it contained only complex carbohydrate moieties; conversely, gp81 contained mainly high-mannose residues. Polypeptide p73 was immunodetected in the presence of tunicamycin and designated as a nascent recipient of N-linked sugars, whereas gp88 was considered to contain O-linked oligosaccharides because its synthesis was not affected by tunicamycin. The ionophore monensin inhibited production of mature gp98, but other intermediate forms, including gp90, were detected. Since the latter product was similar in molecular weight to the desialated form of gp98, one effect of monensin treatment of varicella-zoster virus-infected cells was to block the addition of N-acetylneuraminic acid. Monensin also blocked insertion of gp98 into the plasma membrane and, as determined by electron microscopy, inhibited envelopment of the nucleocapsid and its transport within the cytoplasm. On the basis of this study, we reached the following conclusions: the primary antibody 3B3-binding epitope is located on gp98, gp98 is a mature product of viral glycoprotein processing, gp98 contains both N-linked and O-linked oligosaccharide side chains, gp90 is the desialated penultimate form of gp98, gp88 is an O-linked intermediate of gp98, gp81 is the high-mannose intermediate of gp98, and p73 is the unglycosylated precursor of gp98.
