Abstract

On the basis of the knowledge that the proline-rich hot spot PPPRPP region of P(151)PSNPPPRPP(160), an oligopeptide derived from the cytosolic portion of p22phox (p22), binds to the single functional bis-SH3 domain of the regulatory protein p47phox (p47), we designed a mimetic of the tripeptide PPP based on NMR and X-ray crystallographic data for the p22(151-161) peptide PPSNPPPRPPA with a peptide construct. Incorporation of the synthetic pseudo-triproline mimetic Pro-Pro-Cyp in a molecule derived from molecular modeling studies led to only a 7-fold diminution in activity in a surface plasmon resonance assay relative to the same molecule containing the natural Pro-Pro-Pro tripeptide. The alternative sequence corresponding to a Pro-Cyp-Pro insertion was inactive. This is a first example of the use of a triproline mimetic to interfere with the formation of the p47-p22 complex, which is critical for the activation of NOX, leading to the production of reactive oxygen species as superoxide anions.

53. The Nature of Scientific Explanation: Examining the Perceptions of the Nature, Quality, and 'Goodness' of Explanation among College Students, Science Teachers, and Scientists

Author

Alameh, Sahar, Abd-El-Khalick, Fouad, and Brown, David

Abstract

Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform efforts. Nonetheless, there is a dearth of research on conceptualizing explanation in science education. Using a philosophically guided framework--the Nature of Scientific Explanation (NOSE) framework--the study aims to elucidate and compare college freshmen science students', secondary science teachers', and practicing scientists' scientific explanations and their views of scientific explanations. In particular, this study aims to: (1) analyze students', teachers', and scientists' scientific explanations; (2) explore the nuances about how freshman students, science teachers, and practicing scientists construct explanations; and (3) elucidate the criteria that participants use in analyzing scientific explanations. In two separate interviews, participants first constructed explanations of everyday scientific phenomena and then provided feedback on the explanations constructed by other participants. Major findings showed that, when analyzed using NOSE framework, participant scientists did significantly "better" than teachers and students. Our analysis revealed that scientists, teachers, and students share a lot of similarities in how they construct their explanations in science. However, they differ in some key dimensions. The present study highlighted the need articulated by many researchers in science education to understand additional aspects specific to scientific explanation. The present findings provide an initial analytical framework for examining students' and science teachers' scientific explanations.

59. Nuclear data evaluation with Bayesian networks

Abstract

Bayesian networks are graphical models to represent the probabilistic relationships between variables in the Bayesian framework. The knowledge of all variables can be updated using new information about some of the variables. We show that relying on the Bayesian network interpretation enables large scale inference and gives flexibility in incorporating prior assumptions and constraints into the nuclear data evaluation process, such as sum rules and the non-negativity of cross sections. The latter constraint is accounted for by a non-linear transformation and therefore we also discuss inference in Bayesian networks with non-linear relationships. Using Bayesian networks, the evaluation process yields detailed information, such as posterior estimates and uncertainties of all statistical and systematic errors. We also elaborate on a sparse Gaussian process construction compatible with the Bayesian network framework that can for instance be used as prior on energy-dependent model parameters, model deficiencies and energy-dependent systematic errors of experiments. We present three proof-of-concept examples that emerged in the context of the neutron data standards project and in the ongoing international evaluation efforts of $^{56}$Fe. In the first example we demonstrate the modelization and explicit estimation of relative energy-dependent error components of experimental datasets. Then we show an example evaluation using the outlined Gaussian process construction in an evaluation of $^{56}$Fe in the energy range between one and two MeV, where R-Matrix and nuclear model fits are difficult. Finally, we present a model-based evaluation of $^{56}$Fe between 5 MeV and 30 MeV with a sound treatment of model deficiencies. The R scripts to reproduce the Bayesian network examples and the nucdataBaynet package for Bayesian network modeling and inference have been made publicly available., Comment: 38 pages, 12 figures

60. Cordiality of Digraphs

Subjects
Mathematics - Combinatorics
Abstract

A $(0,1)$-labelling of a set is said to be {\em friendly} if approximately one half the elements of the set are labelled 0 and one half labelled 1. Let $g$ be a labelling of the edge set of a graph that is induced by a labelling $f$ of the vertex set. If both $g$ and $f$ are friendly then $g$ is said to be a {\em cordial} labelling of the graph. We extend this concept to directed graphs and investigate the cordiality of sets of directed graphs. We investigate a specific type of cordiality on digraphs, a restriction of quasigroup-cordiality called $(2,3)$-cordiality. A directed graph is $(2,3)$-cordial if there is a friendly labelling $f$ of the vertex set which induces a $(1,-1,0)$-labelling of the arc set $g$ such that about one third of the arcs are labelled 1, about one third labelled -1 and about one third labelled 0. In particular we determine which tournaments are $(2,3)$-cordial, which orientations of the $n$-wheel are $(2,3)$-cordial, and which orientations of the $n -$fan are $(2,3)$-cordial.

76. Multiscale modelling of type 316H stainless steel to inform creep-fatigue assessment procedures

Author

Brown, David and Smith, Michael

Abstract

The problem of carburisation in austenitic stainless steels poses a risk to the on- going servicability of the UK's Advanced Gas Cooled Reactors. Carburisation affects boiler components due to their exposure to a high temperature, carbon rich environ- ment which leads to a material modification resulting in a hardened, embrittled outer layer. A functionally graded material model is fitted to hardness and EPMA data and used in conjunction with finite element analysis to examine the impact of differing ma- terial property distributions consistent with those observed in carburised components on an internally pressurised pipe; this is compared with the existing R5 method of defining properties in a duplex structure. A positionally dependent form of Fick's Law is solved in a phase field model to predict the evolution of carbon distribution into a grain structure exposed to a carburising environment. The effect of varying the ratio of grain to grain boundary diffusivity is examined with regard to its effect on carbon distribution in the grains and boundaries after the exposure period. Subsequently, ar- tificial hydrostatic stress is introduced to a phase field model of a representative grain structure to determine the extent to which carburisation is impacted by the presence of stress in a component. This is applied both homogenously across the entire examined volume and preferentially on grain boundaries in order to provide a basic analogy to the stresses observed in creep.

Abstract

Accurate nuclear data provide an essential foundation for advances in a wide range of fields, including nuclear energy, nuclear safety and security, safeguards, nuclear medicine, and planetary and space exploration. In these and other critical domains, outdated, imprecise, and incomplete nuclear data can hinder progress, limit precision, and compromise safety. Similar nuclear data needs are shared by many applications, thus prioritizing these needs is especially important and urgently needed. Many levels of analysis are required to prepare nuclear measurements for employment in end-user applications. Because research expertise is typically limited to one level, collaboration across organizations and international borders is essential. This perspective piece provides the latest advances in nuclear data for applications and describes an outlook for both near- and long-term progress in the field.

Abstract

Lithium-ion batteries (LIBs) power virtually all modern portable devices and electric vehicles, and their ubiquity continues to grow. With increasing applications, however, come increasing challenges, especially when operating conditions deviate from room temperature. While high-temperature performance and degradation has been extensively studied in LIBs, sub-zero Celsius performance has received less attention, despite being critical for batteries in transportation roles. Although many individual processes contribute to the capacity loss commonly observed in LIBs at low temperatures, most of them are governed to some extent by the non-aqueous liquid electrolyte present throughout the cell interior. Therefore, electrolyte engineering presents an unparalleled opportunity to study and address the fundamental causes of low-temperature failure. In this review, we first briefly cover the various processes that determine lithium-ion performance below 0 °C. Then, we outline recent literature on electrolyte-based strategies to improve said performance, including various additives, solvents and lithium salts. Finally, we summarize these findings and provide some perspectives on the current state of the field, including promising new areas of investigation.

Abstract

Suppliers and large buyers of electricity often sign load-following forward contracts (LFFCs). A LFFC obligates an electricity supplier to deliver at a pre-specified unit price a fraction of the buyer's ultimate demand for electricity. We show that relative to more standard ('swap') forward contracts, LFFCs can reduce the variation in the wholesale price of electricity. However, LFFCs also can increase the expected wholesale price and thereby reduce expected consumer surplus and total surplus. Keywords: Load-following forward contracts, Swap contracts, Electricity sector, 1. INTRODUCTION Electricity is commonly purchased and sold in wholesale (spot) markets. The price of electricity can vary widely in such markets, depending on prevailing demand and supply conditions. Forward [...]
