Memory access buffering in multiprocessors (1986)

In highly-pipelined machines, instructions and data are prefetched and buffered in both the processor and the cache. This is done to reduce the average memory access latency and to take advantage of memory interleaving. Lock-up free caches are designed to avoid processor blocking on a cache miss. Write buffers are often included in a pipelined machine to avoid processor waiting on writes. In a shared memory multiprocessor, there are more advantages in buffering memory requests, since each memory access has to traverse the memory- processor interconnection and has to compete with memory requests issued by different processors. Buffering, however, can cause logical problems in multiprocessors. These problems are aggravated if each processor has a private memory in which shared writable data may be present, such as in a cache-based system or in a system with a distributed global memory. In this paper, we analyze the benefits and problems associated with the buffering of memory requests in shared memory multiprocessors. We show that the logical problem of buffering is directly related to the problem of synchronization. A simple model is presented to evaluate the performance improvement resulting from buffering.

Dopant and thermal interaction on SPE formed SiC for NMOS performance enhancement (2009)

The dopant and thermal interaction on solid phase epitaxy (SPE) formed SiC has been investigated. We have studied the impact on substitutional carbon concentration ([C] <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sub</sub> ) from various thermal steps including low temperature anneal, SiGe epitaxy thermal budget, RTP, and laser anneal (LSA). Regarding the integration scheme for implementing embedded SiC (eSiC) S/D on NMOS performance enhancement, both post-LDD and post-S/D schemes were studied. The higher [C] <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sub</sub> in post-LDD scheme was observed and the S/D dopants were found to enhance the carbon precipitation into interstitial with conventional RTP/LSA activation thermal processes. The phosphorous implant is also found to degrade [C] <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sub</sub> in comparison to As implant. The higher [C] <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sub</sub> and proximity to channel of formed eSiC in post-LDD scheme are beneficial to device performance. The fabricated eSiC S/D NMOS shows 31% mobility improvement and 7% current enhancement.

Histone H3 and H4 gene deletions in Saccharomyces cerevisiae. (1988)

The genome of haploid Saccharomyces cerevisiae contains two nonallelic sets of histone H3 and H4 genes. Strains with deletions of each of these loci were constructed by gene replacement techniques. Mutants containing deletions of either gene set were viable, however meiotic segregants lacking both histone H3 and H4 gene loci were inviable. In haploid cells no phenotypic expression of the histone gene deletions was observed; deletion mutants had wild-type growth rates, were not temperature sensitive for growth, and mated normally. However, diploids homozygous for the H3-H4 gene deletions were slightly defective in their growth and cell cycle progression. The generation times of the diploid mutants were longer than wild-type cells, the size distributions of cells from exponentially growing cultures were skewed towards larger cell volumes, and the G1 period of the mutant cells was longer than that of the wild-type diploid. The homozygous deletion of the copy-II set of H3-H4 genes in diploids also increased the frequency of mitotic chromosome loss as measured using a circular plasmid minichromosome assay.
A taxonomy of reconfiguration techniques for fault-tolerant processor arrays (1990)

Focuses on the characterization and classification of reconfiguration techniques. The techniques are differentiated according to the type of redundancy (time or hardware), allocation of redundancy (local or global), replacement unit, (processor or a set of processors), switching domain (global or local), and switching implementation (switching element, bus, or network). Typical techniques from four major classes-set switching, processor switching, local redundancy, and time redundancy-are reviewed. The proposed taxonomy can be used as a guide for future research in design and analysis of reconfiguration schemes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Distributed Controller for Load Balancing with VM Migration (2019)

In this paper, we propose a model named Hugo, that acts as a distributed, scalable cloud controller which can handle basic operations like creation, deletion and migration of virtual machines(VMs). It achieves higher utilization by overcommitting the physical machine(PM). We describe each and every component along with their functionalities that garner to form the structural support for the model proposed. Algorithmic implementations namely Wiener filter algorithm for resource prediction, heuristic for energy efficient VM migration are discussed. Distributed nature of the model along with its contribution to scalability is fairly explained in this paper.
Idebenone in Friedreich's ataxia (2008)

Idebenone is well tolerated in paediatric and adult patients. Most trials demonstrated a positive effect on cardiac hypertrophy. The neurological function is in general not modified in adult patients, but a dose-dependent effect was demonstrated in young Friedreich's ataxia patients. Further double-blinded high-dose trials should evaluate idebenone in Friedreich's ataxia early in the disease course.
Development of a Reduced Crude Cracking Catalyst (1988)

Faced with the need of obtaining more transportation fuels from a barrel of crude, Ashland developed the Reduced Crude Conversion Process (RCC®). To support this development, a residuum or reduced crude cracking catalyst was developed and over 1,000 tons were produced and employed in commercial operation. The catalyst possessed a large pore volume, dual pore structure, an Ultrastable Y zeolite with an acidic matrix equal in acidity to the acidity of the zeolite, and was partially treated with rare earth to enhance cracking activity and to resist vanadium poisoning. While subsequently replaced by further improved catalysts, the catalyst achieved high selectivity, was metal resistant at 7,800 ppm nickel plus vanadium, and achieved design projections during start-up and two months of commercial operation. Development of the catalyst served to stimulate research efforts by the catalyst industry to introduce other advanced residuum processing catalysts.
A neural-network architecture for syntax analysis (1999)

Artificial neural networks (ANN's), due to their inherent parallelism, offer an attractive paradigm for implementation of symbol processing systems for applications in computer science and artificial intelligence. This paper explores systematic synthesis of modular neural-network architectures for syntax analysis using a prespecified grammar--a prototypical symbol processing task which finds applications in programming language interpretation, syntax analysis of symbolic expressions, and high-performance compilers. The proposed architecture is assembled from ANN components for lexical analysis, stack, parsing and parse tree construction. Each of these modules takes advantage of parallel content-based pattern matching using a neural associative memory. The proposed neural-network architecture for syntax analysis provides a relatively efficient and high performance alternative to current computer systems for applications that involve parsing of LR grammars which constitute a widely used subset of deterministic context-free grammars. Comparison of quantitatively estimated performance of such a system [implemented using current CMOS very large scale integration (VLSI) technology] with that of conventional computers demonstrates the benefits of massively parallel neural-network architectures for symbol processing applications.

Microwave-Assisted Facile One-Step Carbamoylation of 6-Aminouracils (2005)

Carbamoylation of 6-aminouracils was achieved by reacting 6-aminouracils with isocyanates under computer-controlled microwave irradiation for a short reaction time. Under known thermal conditions, most of carbamoylated uracils are obtained in poor yields with long reaction times.
Mucopolysaccharidosis Type VI (Maroteaux-Lamy Syndrome) (1973)

Sulfatase B activity was deficient in tissues from patients with type VI mucopolysaccharidosis (Maroteaux-Lamy syndrome; MPS VI). Liver, kidney, spleen, brain, and cultured fibroblasts all showed deficient activity. The sulfatase B deficiency was most evident in assays of pellet fractions. Sulfatase B activity was not reduced in the other mucopolysaccharidoses tested (types I, II, and III). The activities of control lysosomal enzymes (sulfatase A and acid phosphatase) were not reduced in MPS VI tissues. The evidence suggests that a sulfatase B deficiency may underlie the biochemical abnormalities responsible for the MaroteauxLamy syndrome. The findings also lend credence to the view that sulfatase B normally plays a catabolic role as an O-sulfatase in the pathways of sulfated mucopolysaccharide metabolism. The possibility that oligosaccharide chondroitin sulfate B (dermatan sulfate) is a substrate for sulfatase B remains to be critically tested.
Fourteen years of plant proteomics reflected in <i>Proteomics</i> : Moving from model species and 2DE‐based approaches to orphan species and gel‐free platforms (2014)

In this article, the topic of plant proteomics is reviewed based on related papers published in the journal Proteomics since publication of the first issue in 2001. In total, around 300 original papers and 41 reviews published in Proteomics between 2000 and 2014 have been surveyed. Our main objective for this review is to help bridge the gap between plant biologists and proteomics technologists, two often very separate groups. Over the past years a number of reviews on plant proteomics have been published . To avoid repetition we have focused on more recent literature published after 2010, and have chosen to rather make continuous reference to older publications. The use of the latest proteomics techniques and their integration with other approaches in the "systems biology" direction are discussed more in detail. Finally we comment on the recent history, state of the art, and future directions of plant proteomics, using publications in Proteomics to illustrate the progress in the field. The review is organized into two major blocks, the first devoted to provide an overview of experimental systems (plants, plant organs, biological processes) and the second one to the methodology.

A mathematical framework for a general purpose constraint management system (1998)

The use of constraints in engineering for designing complex models is very popular. Current constraint solvers are divided into two broad classes: general and domain specific. Those that are general can handle very general constraint problems but are typically slow; while those that are domain specific can handle only a specific type of problem but are typically fast. For example, numerical algorithms are slow but general, whilst local propagation techniques are fast but limited to simple problems.\n\nIt is generally acknowledged that there is a close coupling between engineering constraints and geometric constraints in the design process and so the solution of constraint problems consisting of engineering and geometric constraints is an important research issue. Some authors attempt to overcome the expressive limitations of domain specific solvers by using hybrid systems which try to find a balance between the speed of domain specific solvers and the generality of general solvers.\n\nPrevious research at the University of Leeds has led to the development of a number of domain specific solvers that are capable of solving geometric and engineering constraint problems separately. In particular, the Leeds solvers are incremental and can find solutions when a new constraint is added very quickly. This thesis investigates the use of a hybrid of the various Leeds solvers with an aim to interactively solving constraint problems in engineering design, This Hybrid would have the speed advantages of the domain specific solvers and the expressiveness of a more general solver. In order for the hybrid to be constructed, commonalties of existing engineering constraints solvers must be identified. A characterisation of existing constraint solvers leads to the identification of a number of issues that need to be addressed before the hybrid can be built.\n\nIn order to examine these issues, a framework for the constraint satisfaction process is presented that allows abstractions of constraint definition, constraint representation and constraint satisfaction. Using the constraint satisfaction framework, it is possible to study the quality of solution of constraint solvers. This leads to the identification of important problems in current constraint solvers.\n\nThe constraint process framework leads to a study of the use of various paradigms of collaboration within the hybrid, such as sequential, parallel and concurrent. The study of the quality of solution allows concrete statements to be made about the hybrid collaborations. A new incremental constraint solver is presented that uses the hybrid collaboration paradigms and provides a first step towards a powerful engineering constraint solver.
논문 / 노예제폐지론의 인종 성 계급 : 해석의 역사 (1999)

The Civil Rights Movement in the 1960`s has greatly changed the American society, It has also influenced the studies on Abolitionism. Before the 1960`s there were two groups of historians who studied antislavery movements in the 1830`s. The first group was traditional historians. They thought the abolitionists as $quot;moral heroes.$quot; And the other was so-called revisionist historians. They dealt with the abolitionists as $quot;fanatics$quot; whose agitation was a cause of the needless Civil War. This interpretation of the revisionists dominated American historiography of abolitionism through the 1930`s and 1940`s and remained very influential until the 1960`s. In this article I have tried to find some recent trends in the studies on antislavery movement in America. To do this, I focused on some changes which has happened from the 1960`s to the present. Although the revisionists did not deny that antislavery movement was a religious and moral crusade against slavery, they saw Theodore Weld and James Gillespie Birney as the central figures of the movement. They thought William Lloyd Garrison as a fanatic. From the 1960`s revisionist`s interpretation was challenged by some historians. The critics of revisionists insisted that the Garrisonian abolitionists were not fanatics. The change originated in the 1960`s has three directions: reconsideration on the racism of abolitionists, more in-depth studies on black abolitionists, and studies on correlation between abolitionism and the early women`s movement. Until recent time no one questioned about white abolitionists` racism because they devoted their lives to abolishing slavery. But recent works concluded that white abolitionists had racial prejudice against black abolitionists. In addition the 1970`s saw a new trend of extensive studies on black abolitionists. These trends may continue in the future. Finally, the most distinguished contemporary research topic on abolitionism is feminist abolitionists. In the last part of the article, I mentioned debates about the origins of the antislavery movement. In his article in American Historical Review, Thomas Haskell criticized David Brion Davis` thesis about the ideological hegemony of abolitionists. Against this critics Davis replied in the same journal that Haskell misunderstood his thesis. During these debates John Ashworth took almost the same side with Davis. Both of them criticized the market economy theory that Haskell stood on. Although the debates started with the question of the origins of antislavery movement, it seems to develop into the other area of history like historical explanation.
Suitability of a Dehydrated Poultry Mortality-Soybean Meal Product for Use in Broiler Chicken Diets (2003)

In the poultry industry, several alternative methods for disposal of dead birds have been developed. This study evaluated the efficacy of a dehydrated poultry mortality-soybean meal (DPSM) product, made from 60% on-farm whole dead birds, 40% soybean oil meal, and a preservative amendment, for inclusion in broiler diets. Composite samples of the DPSM product were obtained for nutritional and microbiological analysis. A subsequent 42-d broiler growout experiment was conducted using DPSM incrementally (0 to 100%) substituted for the protein source component (i.e., soybean oil meal) in starter and grower diets. Nutritionally, the DPSM product was similar to soybean oil meal (SBOM), with approximately 51.5% CP, 2.81% Lys, 0.72% Met, 1.85% Thr, 3.14% Arg, and 1.36% TSAA. True amino acid digestibilities of DPSM, however, were higher than soybean oil meal. Likewise, crude fat (18.03%) and ash (8.00%) concentrations of DPSM were higher than those typically observed for SBOM. Although at low levels, 13 genera of bacteria (including some pathogenic organisms) were isolated from the DPSM product. When replacing SBOM in broiler starter and grower diets, DPSM, at lower, more practical replacement rates, did not significantly influence body weight, feed consumption, or feed conversion. According to the results of this study, using DPSM in partial substitution for SBOM in broiler diets was a safe, efficient, and economically feasible alternative for dead bird disposal.
The professional estate (1949)

General Electric's President Wilson takes his cue from Emerson's essay, “The American Scholar,” in this article in which he points out to the engineer his responsibility, as a thinking man, to the society in which he lives. The professional man cannot, in good conscience, confine himself within the limits of his own technical sphere; he must learn to phrase his ideas in terms of the world.

Calculating Point of Origin of Blood Spatter Using Laser Scanning Technology (2015)

The point of origin of an impact pattern is important in establishing the chain of events in a bloodletting incident. In this study, the accuracy and reproducibility of the point of origin estimation using the FARO Scene software with the FARO Focus(3D) laser scanner was determined. Five impact patterns were created for each of three combinations of distances from the floor (z) and the front wall (x). Fifteen spatters were created using a custom impact rig, scanned using the laser scanner, photographed using a DSLR camera, and processed using the Scene software. Overall results gave a SD = 3.49 cm (p < 0.0001) in the x-direction, SD = 1.14 cm (p = 0.9291) in the y-direction, and SD = 9.08 cm (p < 0.0115) in the z-direction. The technique performs within literature ranges of accepted accuracy and reproducibility and is comparable to results reported for other virtual stringing software.
cDNA Sequence of Porcine Thioredoxin (2002)

Several mammalian thioredoxin cDNA sequences, namely that of human, macaca, ovine, bovine, equine and murine have been already registered in the Genbank database; but that of porcine is still not known. In this communication, we report the full-length cDNA sequence of porcine thioredoxin as determined by RT-PCR method. We also compared the protein sequence of thioredoxin from various mammals. Multialignment of the amino acid sequences between porcine and other mammalian species revealed that the sequences are highly conserved. Only one difference exists between the amino acid sequences of porcine and bovine thioredoxin.
