Are the U.S. Stock Market and Credit Default Swap Market Related? (2008)

This article examines the market-wide relations between the U.S. stock market and the credit default swap (CDS) market for the period 2001–2007. Results indicate that the lead-lag relationship between the U.S. stock market and the CDS market depends on the credit quality of the underlying reference entity. Specifically, this article finds significant mutual feedback of information between the stock market and the high-yield CDS market in terms of pricing and volatility, while the stock market leads the investment-grade CDS index in the pricing process. The CDS market seems to play a more significant role in volatility spillover than the stock market. That is, volatilities of both the investment-grade and high-yield CDS indices seem to lead the stock market volatility, while the latter has a feedback effect to that of the high-yield CDS market only. Overall, the implication is that market participants should seek information in both markets when they are about to engage in trading and/or hedging <b>TOPICS:</b>Security analysis and valuation, credit default swaps, financial crises and financial market history, credit risk management
Trust and nuanced profile similarity in online social networks (2009)

Online social networks, where users maintain lists of friends and express their preferences for items like movies, music, or books, are very popular. The Web-based nature of this information makes it ideal for use in a variety of intelligent systems that can take advantage of the users' social and personal data. For those systems to be effective, however, it is important to understand the relationship between social and personal preferences. In this work we investigate features of profile similarity and how those relate to the way users determine trust. Through a controlled study, we isolate several profile features beyond overall similarity that affect how much subjects trust hypothetical users. We then use data from FilmTrust, a real social network where users rate movies, and show that the profile features discovered in the experiment allow us to more accurately predict trust than when using only overall similarity. In this article, we present these experimental results and discuss the potential implications for using trust in user interfaces.
A comparative study of load sharing in heterogeneous multicomputer systems (1992)

The effective use of a heterogeneous multicomputer system depends on the scheduling policy used. Often the scheduling algorithms used are those that were intended for homogeneous systems. On the other hand, most scheduling algorithms designed with heterogeneity in mind were developed under unrealistic assumptions. To enhance the performance of a multicomputer system, load sharing can be used during scheduling to distribute the workload evenly among the constituent nodes. This paper presents a comprehensive evaluation of load sharing algorithms in heterogeneous multicomputer systems. The simulation results suggest that load sharing policies that perform well in homogeneous systems fail to achieve good performance in heterogeneous systems. The authors also show that the distribution of service time and the communication overhead have significant impact on system performance. They conclude by providing guidelines for selecting load sharing policies suitable for different heterogeneous environments. >
Renal sympathetic nerve activity modulates afferent renal nerve activity by PGE<sub>2</sub>-dependent activation of α<sub>1</sub>- and α<sub>2</sub>-adrenoceptors on renal sensory nerve fibers (2007)

Increasing efferent renal sympathetic nerve activity (ERSNA) increases afferent renal nerve activity (ARNA). To test whether the ERSNA-induced increases in ARNA involved norepinephrine activating alpha-adrenoceptors on the renal sensory nerves, we examined the effects of renal pelvic administration of the alpha(1)- and alpha(2)-adrenoceptor antagonists prazosin and rauwolscine on the ARNA responses to reflex increases in ERSNA (placing the rat's tail in 49 degrees C water) and renal pelvic perfusion with norepinephrine in anesthetized rats. Hot tail increased ERSNA and ARNA, 6,930 +/- 900 and 4,870 +/- 670%.s (area under the curve ARNA vs. time). Renal pelvic perfusion with norepinephrine increased ARNA 1,870 +/- 210%.s. Immunohistochemical studies showed that the sympathetic and sensory nerves were closely related in the pelvic wall. Renal pelvic perfusion with prazosin blocked and rauwolscine enhanced the ARNA responses to reflex increases in ERSNA and norepinephrine. Studies in a denervated renal pelvic wall preparation showed that norepinephrine increased substance P release, from 8 +/- 1 to 16 +/- 1 pg/min, and PGE(2) release, from 77 +/- 11 to 161 +/- 23 pg/min, suggesting a role for PGE(2) in the norepinephrine-induced activation of renal sensory nerves. Prazosin and indomethacin reduced and rauwolscine enhanced the norepinephrine-induced increases in substance P and PGE(2). PGE(2) enhanced the norepinephrine-induced activation of renal sensory nerves by stimulation of EP4 receptors. Interaction between ERSNA and ARNA is modulated by norepinephrine, which increases and decreases the activation of the renal sensory nerves by stimulating alpha(1)- and alpha(2)-adrenoceptors, respectively, on the renal pelvic sensory nerve fibers. Norepinephrine-induced activation of the sensory nerves is dependent on renal pelvic synthesis/release of PGE(2).
Subcellular localization of alkaline phosphatase in Bacillus licheniformis 749/C by immunoelectron microscopy with colloidal gold (1984)

Subcellular distribution of the alkaline phosphatase of Bacillus licheniformis 749/C was determined by an immunoelectron microscopy method. Anti-alkaline phosphatase antibody labeled with 15- to 18-nm colloidal gold particles (gold-immunoglobulin G [IgG] complex) were used for the study. Both the plasma membrane and cytoplasmic material were labeled with the gold-IgG particles. These particles formed clusters in association with the plasma membrane; in contrast, in the cytoplasm the particles were largely dispersed, and only a few clusters were found. The gold-IgG binding was quantitatively estimated by stereological analysis of labeled, frozen thin sections. This estimation of a variety of control samples showed that the labeling was specific for the alkaline phosphatase. Cluster formation of the gold-IgG particles in association with the plasma membrane suggests that existence of specific alkaline phosphatase binding sites (receptors) in the plasma membrane of B. licheniformis 749/C.
A Trust Evaluation Model for Online Social Networks (2018)

With the rapid prevalence of online social networks, the trustworthiness of online users has become a current issue in the field of social computing. The evaluation of trust in social networks has been widely used in situations such as friend-recommendation, e-commerce and trust based access control systems. Security is the backbone of social networks. For sharing and exchanging of information between the trusted users only trustworthiness of the user needs to be determined. One of the key requirements in trust applications is recognizing the trustworthy actors in the network. In the proposed research, a general trust framework will be introduced to calculate the node trust values for social network users by applying reinforcement learning methods. Firstly, some selected features of social network are used as the training feature and the measurement whether there is an edge between nodes used as label information. Secondly, a training model will be used to calculate the node trust value. Then a recommendation algorithm will be used to calculate node trust score. Finally, the simulation is used to verify the performance of suggested method. For the simulation of experimentation, data from an adaptive social network will be used.
Occurrence of Species of <i>Aspergillus</i> and <i>Penicillium</i> in Roots of Wheat and Ryegrass and Their Effects on Root Rot Caused by <i>Gaeumannomyces graminis</i> var. <i>Tritici</i> (1988)

Aspergillus fumigatus, A. terreus, Emericella nidulans, E, quadrilineata, Penicillium aculeatum, P. brevicompactum, P. chrysogenum, P. citreonigrum, P. corylophilum, P. fuscum, P. griseofulvum, P. janthinellum, P. nigricans, P. purpurogenum, P. restrictum, P. turbatum, P. verruculosum, Eupenicillium sp. and E. euglaucum were isolated from roots of wheat and ryegrass at seedling, tillering, stem extension, milky ripe and ripe for cutting stages. Frequency of occurrence of species of Aspergillus and Penicillium were higher in roots subjected to washing only and plated onto PDA or PDA amended with lactic acid. In general, species of these two genera were common at the stem extension stage. P. nigricans, P. janthinellum, P. griseofulvum, P. fuscum, Eupenicillium sp. and P. turbatum were isolated at a higher frequency than other species. When introduced at 1% inoculum level A. terreus, P. fuscum, P. griseofulvum and P. nigricans caused severe damage to wheat and ryegrass seedlings especially in sterilised Lancelin soil where they reduced the fresh shoot and root weights of the hosts. When these isolates were screened for antagonism towards Gaeumannomyces graminis var. tritici (Ggt) or agar the strongest antagonism was shown by P. griseofulvum, A. terreus, P. nigricans, P. fuscum and P. janthinellum, whereas other species of the two genera had little or no effect on Ggt. The presence of A. terreus, P. griseofulvum or P. fuscum. with Ggt decreased root rot of wheat and ryegrass caused by Ggt in sterilised and non-sterilised soil, while P. nigricans showed a similar effect in non-sterilised soil only. However, none of the isolates tested would be suitable as biological control agents.
看護研究におけるミックスメソッドの利用 (特集 結果の信頼性を高めるためのトライアンギュレーション--複数の理論・手法・リソースを組み合わせる研究手法) (2005)

Phylogenetics and the placement of WGDs within highly polyploid lineages continues to be a major challenge. This study adds to the conversation on WGD inference difficulties by demonstrating that sampling is especially important for WGD identification and phylogenetic placement. Given its economic importance and genomic resources, the Brassicales continues to be an ideal group for assessing WGD inference methods.
Compacted Clay Liners and Covers for Arid Sites (1993)

Tests were performed on a clayey soil from a site in Texas to define ranges of water content and dry unit weight at which compacted test specimens would have: (1) Low hydraulic conductivity; (2) minimal potential for shrinkage upon drying; and (3) adequate shear strength. Test specimens were compacted with three compactive energies over a range of water content. Low hydraulic conductivity could be achieved over a broad range of water content, but relatively wet specimens underwent large shrinkage upon drying. A range of water content near the optimum value measured with the highest compactive energy proved to be suitable in meeting the objective of low hydraulic conductivity and shrinkage potential. The dry unit weight had to be greater than 96–98% of the maximum value from modified compaction (ASTM method D1557) to meet hydraulic conductivity, shrinkage, and strength objectives. A similar approach is suggested for development of compaction criteria at other projects in which low‐hydraulic‐conductivity liners or covers must be constructed in relatively arid regions or other situations in which potential cracking caused by desiccation is of concern.
Slew rate enhancement technique for CMOS output buffers (1989)

A novel technique for enhancing the slew rate in CMOS amplifiers is described. The slew enhancement is provided by an auxiliary circuit which is activated only during transients. The core amplifier is not stressed with the large transient currents, thus minimising transient power dissipation and also avoiding signal swing problems. A slew rate of 1 V/μs with a 10000pF load capacitance has been achieved, while requiring a quiescent power dissipation of less than 1.5 mW.
The Measurement and Modelling of Commercial Real Estate Performance (2004)

ABSTRACT In this paper we discuss methods of developing real estate indices, the availability of real estate data, the problems of using published real estate data and how real estate data can be used for stochastic investment modelling for actuarial purposes. In recent years there have been many developments in the collection, presentation and analysis of real estate data that have not found their way into the actuarial literature. We review those developments and suggest and develop ways in which raw real estate investment data can be used for actuarial purposes. We then review the Wilkie real estate stochastic investment model and use the research of real estate finance academics to inform a critique and development of that model. In developing the models, different data sets are used, including data from valuation-based and de-smoothed indices in order to find appropriate parameter estimates. The significance (or otherwise) of the parameter estimates is tested for each of the fitted models and the differences between the fitted models are examined. By reviewing research in the real estate finance field, making use of the latest research and developing original work, the main aim of this paper is to ensure that actuaries have the means to collect, understand and manipulate real estate data for performance measurement and investment modelling purposes.
Prediction of protein signal sequences and their cleavage sites (2000)

Protein signal sequences play a central role in the targeting and translocation of nearly all secreted proteins and many integral membrane proteins in both prokaryotes and eukaryotes. The knowledge of signal sequences has become a crucial tool for pharmaceutical scientists who genetically modify bacteria, plants, and animals to produce effective drugs. However, to effectively use such a tool, the first important thing is to find a fast and effective method to identify the "zipcode" entity; this is also evoked by both the huge amount of unprocessed data available and the industrial need to find more effective vehicles for the production of proteins in recombinant systems. In view of this, a sequence-encoded algorithm was developed to identify the signal sequences and predict their cleavage sites. The rate of correct prediction for 1,939 secretory proteins and 1,440 nonsecretory proteins by self-consistency test is 90.14% and that by jackknife test is 90.13%. The encouraging results indicate that the signal sequences share some common features although they lack similarity in sequence, length, and even composition and that they are predictable to a considerably accurate extent.
MiR-221 Influences Effector Functions and Actin Cytoskeleton in Mast Cells (2011)

Mast cells have essential effector and immunoregulatory functions in IgE-associated allergic disorders and certain innate and adaptive immune responses, but the role of miRNAs in regulating mast cell functions is almost completely unexplored. To examine the role of the activation-induced miRNA miR-221 in mouse mast cells, we developed robust lentiviral systems for miRNA overexpression and depletion. While miR-221 favored mast cell adhesion and migration towards SCF or antigen in trans-well migration assays, as well as cytokine production and degranulation in response to IgE-antigen complexes, neither miR-221 overexpression, nor its ablation, interfered with mast cell differentiation. Transcriptional profiling of miR-221-overexpressing mast cells revealed modulation of many transcripts, including several associated with the cytoskeleton; indeed, miR-221 overexpression was associated with reproducible increases in cortical actin in mast cells, and with altered cellular shape and cell cycle in murine fibroblasts. Our bioinformatics analysis showed that this effect was likely mediated by the composite effect of miR-221 on many primary and secondary targets in resting cells. Indeed, miR-221-induced cellular alterations could not be recapitulated by knockdown of one of the major targets of miR-221. We propose a model in which miR-221 has two different roles in mast cells: in resting cells, basal levels of miR-221 contribute to the regulation of the cell cycle and cytoskeleton, a general mechanism probably common to other miR-221-expressing cell types, such as fibroblasts. Vice versa, upon induction in response to mast cell stimulation, miR-221 effects are mast cell-specific and activation-dependent, contributing to the regulation of degranulation, cytokine production and cell adherence. Our studies provide new insights into the roles of miR-221 in mast cell biology, and identify novel mechanisms that may contribute to mast cell-related pathological conditions, such as asthma, allergy and mastocytosis.
Performance analysis of parallel hub diverging casing axial annular diffuser with 20° equivalent cone angle (2014)

The performance of axial annular diffuser with parallel hub and diverging casing for same equivalent cone angle of 20° has been analysed with the help of computational fluid dynamics for area ratio 2,3 and 4. The analysis has been carried out for flow regime with various experimentally obtained inlet velocity profiles for area ratio 2 with or without swirl. The flow behaviour inside the annular diffuser was analysed and pressure recovery coefficient was computed which agrees reasonably well with the experimental/available data. Further prediction of flow behaviour inside the annular diffuser and the expected pressure recovery coefficient has been computed.
Auto-DR and Pre-cooling of Buildings at Tri-City Corporate Center (2008)

Over the several past years, Lawrence Berkeley National Laboratory (LBNL) has conducted field tests for different pre-cooling strategies in different commercial buildings within California. The test results indicated that pre-cooling strategies were effective in reducing electric demand in these buildings during peak periods. This project studied how to optimize pre-cooling strategies for eleven buildings in the Tri-City Corporate Center, San Bernardino, California with the assistance of a building energy simulation tool -- the Demand Response Quick Assessment Tool (DRQAT) developed by LBNL's Demand Response Research Center funded by the California Energy Commission's Public Interest Energy Research (PIER) Program. From the simulation results of these eleven buildings, optimal pre-cooling and temperature reset strategies were developed. The study shows that after refining and calibrating initial models with measured data, the accuracy of the models can be greatly improved and the models can be used to predict load reductions for automated demand response (Auto-DR) events. This study summarizes the optimization experience of the procedure to develop and calibrate building models in DRQAT. In order to confirm the actual effect of demand response strategies, the simulation results were compared to the field test data. The results indicated that the optimal demand response strategies worked well for all buildings in the Tri-City Corporate Center. This study also compares DRQAT with other building energy simulation tools (eQUEST and BEST). The comparison indicate that eQUEST and BEST underestimate the actual demand shed of the pre-cooling strategies due to a flaw in DOE2's simulation engine for treating wall thermal mass. DRQAT is a more accurate tool in predicting thermal mass effects of DR events.

A tool for automatic detection of deadlock in wormhole networks on chip (2008)

We present an extension of Duato's necessary and sufficient condition a routing function must satisfy in order to be deadlock-free, to support environment constraints inducing extra-dependencies between messages. We also present an original algorithm to automatically check the deadlock-freeness of a network with a given routing function. A prototype tool has been developed and automatic deadlock checking of large scale networks with various routing functions have been successfully achieved. We provide comparative results with standard approach, highlighting the benefits of our method.
Laser scanning tomography to diagnose and monitor glaucoma. (1993)

Confocal scanning laser ophthalmoscopes offer practical tools for clinical use to obtain quantitative information of the optic nerve head and peripapillary retina. These instruments acquire objective and quantitative data and can be used in many eyes with undilated pupils and cataracts. Further, they acquire images rapidly and with low-level illumination. Because of wide variability in optic nerve head topography among normal eyes, their usefulness may be limited as a single test for change in the optic nerve head and peripapillary retina. These instruments require validation through widespread use and correlation with other structural and functional tests.
An investigation of gas hydrates formation energetics (2005)

Abstract A method was developed and implemented for predicting enthalpies of gas hydrate formation, which are required for the efficient design of gas hydrate‐based processes. The proposed method is based on the statistical thermodynamic theory of solid solutions and it is thermodynamically consistent. It allows delineation of the various energetic contributions, does not resort to empirical constants enforced by regressions and applies to any simple or multicomponent bulk hydrate equilibrium system at the hydrate point or beyond it. The application of the method was demonstrated for several simple, double and multicomponent gas hydrate systems with one or two equilibrium hydrate phases. It was found that a major energetic component in hydrate formation is the heat of enclathration, defined as the residual enthalpy of the enclathrated gas. All example applications indicated that this property is a constant, independent of temperature, pressure and composition, characteristic only of the individual gas and it was regressed by a general corresponding states analytical expression. © 2005 American Institute of Chemical Engineers AIChE J, 2005
Measurement of Recombination Lifetimes in Superconductors (1967)

It is shown that the experimentally measured quasiparticle recombination lifetime in a superconductor is not the same as the previously calculated theoretical lifetime. A simple expression relating the two is derived.
