Model predictive control based cooperative lane change strategy for improving traffic flow

Lane change has attracted more and more attention in recent years for its negative impact on traffic safety and efficiency. However, few researches addressed the multi vehicle cooperation during lane change process. In this article, feasibility criteria of lane change are designed, which considers the acceptable acceleration/deceleration of neighboring vehicles; meanwhile, a cooperative lane change strategy based on model predictive control is proposed in order to attenuate the adverse impacts of lane change on traffic flow. The proposed strategy implements the centralized decision making and active cooperation among the subject vehicle performing lane change in the subject lane and the preceding vehicle and the following vehicle in the target lane during lane change. Using model predictive control, safety, comfort, and traffic efficiency are integrated as the objectives, and lane change process is optimized. Numerical simulation results of the cooperative lane change strategy suggest that the deceleration of following vehicle can be weakened and further the shock wave propagated in traffic flow can be alleviated to some degree compared with traditional lane change.
Comparison of pectin degrading fungal communities in temperate forests using glycosyl hydrolase family 28 pectinase primers targeting Ascomycete fungi.
Venue: Journal of microbiological methods

Fungi have developed a wide assortment of enzymes to break down pectin, a prevalent polymer in plant cell walls that is important in plant defense and structure. One enzyme family used to degrade pectin is the glycosyl hydrolase family 28 (GH28) In this study we developed primers for the amplification of GH28 coding genes from a database of 293 GH28 sequences from 40 fungal genomes. The primers were used to successfully amplify GH28 pectinases from all Ascomycota cultures tested, but only three out of seven Basidiomycota cultures. In addition, we further tested the primers in PCRs on metagenomic DNA extracted from senesced tree leaves from different forest ecosystems, followed by cloning and sequencing. Taxonomic specificity for Ascomycota GH28 genes was tested by comparing GH28 composition in leaves to internal transcribed spacer (ITS) amplicon composition using pyrosequencing. All sequences obtained from GH28 primers were classified as Ascomycota; in contrast, ITS sequences indicated that fungal communities were up to 39% Basidiomycetes. Analysis of leaf samples indicated that both forest stand and ecosystem type were important in structuring fungal communities. However, site played the prominent role in explaining GH28 composition, whereas ecosystem type was more important for ITS composition, indicating possible genetic drift between populations of fungi. Overall, these primers will have utility in understanding relationships between fungal community composition and ecosystem processes, as well as detection of potentially pathogenic Ascomycetes.

Effect of annealing atmosphere on LiMn2O4 for thin film Li ion batteries from aqueous chemical solution deposition

In this study we demonstrate and explain the direct relationship between precursor chemistry and phase formation of LiMn2O4 powders and thin films from aqueous chemical solution deposition (CSD) The processing conditions applied to transform the precursor into the LiMn2O4 phase are investigated with a focus on the heating atmosphere and temperature. We found that the Mn2+ ions, used as a starting product, already partially oxidize into Mn3+/Mn4+ in the precursor solution. The Mn3+ ions present in the gel or the dried film are extremely sensitive to O2, leading to fast oxidation towards Mn4+ Here, we suggest that the oxygen, introduced in the precursor solution by the citrate complexing agent, suffices to oxidize the Mn2+ into Mn3+/Mn4+ which is crucial in the formation of phase pure spinel and stoichiometric LiMn2O4. Any additional oxygen, available as O2 during the final processing, should be avoided as it leads to further oxidation of the remaining Mn3+ into Mn4+ and to the formation of the g Mn2O3 and l MnO2 secondary phases. Based on these insights, the preparation of phase pure, spinel and stoichiometric LiMn2O4 in a N2 ambient was achieved both in powders and films. Moreover, the study of the precursor chemistry and final annealing leads to the possibility of reducing the final temperature to 450 degC, enabling the use of temperature and oxidation sensitive current collectors such as TiN. This inert ambient and low temperature processing of LiMn2O4 provides the opportunity to have large flexibility and compatibility with process conditions for other materials in the thin film battery stack, without undesired oxidations.
Application of ultrasound to the synthesis of a new nanostructured Mn(II) supramolecular compound: A precursor for g Mn2O3 nanoparticles.
Venue: Ultrasonics sonochemistry

A new nanostructured Mn(II) supramolecular compound [Mn(hpydcH2)2(H2O)4] (1) (hpydcH3=4 hydroxy 2,6 pyridinedicarboxylic acid) has been synthesized using a sonochemical process. The structure of compound 1 was determined by single crystal X ray diffraction and it was revealed that each hpydcH2( anionic ligand has been coordinated to Mn(II) ion in a novel monodentate fashion leaving another functional carboxylic acid group intact. Compound 1 was also characterized by scanning electron microscopy (SEM) X ray powder diffraction (XRPD) FT IR spectroscopy and elemental analysis. Thermal stability of compound 1 was studied by thermal gravimetric (TG) analysis and compared to that of its crystalline analogue. Subsequently, the role of concentration of the initial reactants on the size of nanostructures of compound 1, has been investigated. Compound 1 was proved to be a precursor for g Mn2O3 nanoparticles.
Simple Synthesis of TiO2/MnOx Composite with Enhanced Performances as Anode Materials for Li Ion Battery

Hydrolysis of organic titanate was used to modify g MnO2 to produce a TiO2/MnOx composite as a new anode material with enhanced electrochemical properties for lithium ion battery. The composition, structure, valence state as well as the lithium storage mechanism of the composite have been carefully studied with inductively coupled plasma (ICP) elemental analysis, X ray diffraction(XRD) electron microscopy, X ray photoelectron spectroscopy (XPS) and solid state nuclear magnetic resonance (NMR) spectroscopy. The electrochemical measurement shows that the specific capacity of the composite stays above 972 mAh/g for 100 cycles at a current rate of 100 mA/g, which is much better than g MnO2. The significant improvement can be ascribed to the involvement of both insertion and conversion lithium storage mechanisms owing to the incorporation of a small amount of TiO2 ~5% to MnO2, as well as the presence of Mn2O3 in the composite. This new strategy is expected to be extended to improve the electrochemical properties of other metal oxides for lithium ion battery applications.
Coordination Geometry and Oxidation State Requirements of Corner Sharing MnO6 Octahedra for Water Oxidation Catalysis: An Investigation of Manganite (g MnOOH)

Surface directed corner sharing MnO6 octahedra within numerous manganese oxide compounds containing Mn3+ or Mn4+ oxidation states show strikingly different catalytic activities for water oxidation, paradoxically poorest for Mn4+ oxides, regardless of oxidation assay (photochemical and electrochemical) This is demonstrated herein by comparing crystalline oxides consisting of Mn3+ (manganite, g MnOOH; bixbyite, Mn2O3) Mn4+ (pyrolusite, b MnO2) and multiple monophasic mixed valence manganese oxides. Like all Mn4+ oxides, pure b MnO2 has no detectable catalytic activity, while g MnOOH (tetragonally distorted Mn3+O6, D4h symmetry) is significantly more active and Mn2O3 (trigonal antiprismatic Mn3+O6, D3d symmetry) is the most active. g MnOOH deactivates during catalytic turnover simultaneous with the disappearance of crystallographically defined corner sharing Mn3+O6 and the appearance of Mn4+ In a comparison of 2D layered crystalline birnessites (d MnO2) the monovalent Mn4+ form is catalytically inert, wh.
Gifted microbes for genome mining and natural product discovery
Venue: Journal of Industrial Microbiology Biotechnology

Actinomycetes are historically important sources for secondary metabolites (SMs) with applications in human medicine, animal health, and plant crop protection. It is now clear that actinomycetes and other microorganisms with large genomes have the capacity to produce many more SMs than was anticipated from standard fermentation studies. Indeed ~90 of SM gene clusters (SMGCs) predicted from genome sequencing are cryptic under conventional fermentation and analytical analyses. Previous studies have suggested that among the actinomycetes with large genomes, some have the coding capacity to produce many more SMs than others, and that strains with the largest genomes tend to be the most gifted. These contentions have been evaluated more quantitatively by antiSMASH 3.0 analyses of microbial genomes, and the results indicate that many actinomycetes with large genomes are gifted for SM production, encoding 20 50 SMGCs, and devoting 0.8 3.0 Mb of coding capacity to SM production. Several Proteobacteria and Firmacutes with large genomes encode 20 30 SMGCs and devote 0.8 1.3 Mb of DNA to SM production, whereas cultured bacteria and archaea with small genomes devote insignificant coding capacity to SM production. Fully sequenced genomes of uncultured bacteria and archaea have small genomes nearly devoid of SMGCs.
Universal screening increases the representation of low income and minority students in gifted education
Venue: Proceedings of the National Academy of Sciences

A longstanding concern about gifted education in the United States is the underrepresentation of minorities and economically disadvantaged groups. One explanation for this gap is that standard processes for identifying gifted students, which are based largely on the referrals of parents and teachers, tend to miss many qualified students. Consistent with this hypothesis, we find that a universal screening program in a large urban school district led to significant increases in the numbers of poor and minority students who met the IQ standards for gifted status. Our findings raise the question of whether a systemic failure to identify qualified students from all backgrounds may help explain the broader pattern of minority underrepresentation in all advanced K 12 academic programs. Low income and minority students are substantially underrepresented in gifted education programs. The disparities persist despite efforts by many states and school districts to broaden participation through changes in their eligibility criteria. One explanation for the persistent gap is that standard processes for identifying gifted students, which are based largely on the referrals of parents and teachers, tend to miss qualified students from underrepresented groups. We study this hypothesis using the experiences of a large urban school district following the introduction of a universal screening program for second graders. Without any changes in the standards for gifted eligibility, the screening program led to large increases in the fractions of economically disadvantaged and minority students placed in gifted programs. Comparisons of the newly identified gifted students with those who would have been placed in the absence of screening show that Blacks and Hispanics, free/reduced price lunch participants, English language learners, and girls were all systematically "underreferred" in the traditional parent/teacher referral system. Our findings suggest that parents and teachers often fail to recognize the potential of poor and minority students and those with limited English proficiency.
The Impact of the Nomination Stage on Gifted Program Identification

The use of the nomination stage as the first step in the identification process is pervasive across the field of gifted education. In many cases, nominations are used to limit the number of students who will need to be evaluated using costly and time consuming assessments for the purpose of gifted program identification and placement. This study evaluated the effect of the nomination stage on the overall efficacy of a gifted identification system. Results showed that in nearly all conditions, identification systems that require a nomination before testing result in a large proportion of gifted students being missed. Under commonly implemented conditions, the nomination stage can cause the false negative rate to easily exceed 60% Changes to identification practices are urgently needed in order to ensure that larger numbers of gifted students receive appropriate educational placement and to maintain the integrity of gifted education services.
ACCEL: A New Model for Identifying the Gifted

Serious identification of the gifted started with the work of Lewis Terman early in the 20th century. Terman's model, based largely on IQ, may have made sense in the early 20th century, but it no longer makes sense today. The problems that society needs its gifted individuals to solve in the 21st century require much more than IQ in addition to analytical, IQ like skills, they also require creative, practical, wisdom based, and ethical skills. In this essay, I discuss some of the background for the conventional IQ based model of gifted identification and education and then consider the problems the world faces today and why IQ is insufficient to solve them. I then present a new model ACCEL (Active Concerned Citizenship and Ethical Leadership) that perhaps will better prepare our gifted students for the world of the future.
The role of trust building mechanisms in entering into network coopetition: The case of tourism networks in Poland

While dyadic coopetition drivers have been explored in a number of studies, network coopetition has not received similar attention. Available studies tackle network coopetition from the central actor's perspective, leaving other members beyond the scope of attention. In this study, we aim to develop the understanding of network coopetition adherence by exploring the role of trust building mechanisms. Interviews with 66 key stakeholders in a mountain tourism destination have been analysed through the lens of the five trust building mechanisms. Our findings indicate that transference by third party legitimization and reputation in the network play a vital role in the decision to enter into network coopetition. Inversely, calculative, capability based and intention based trust are shown to be difficult to develop and are rarely used. This paper discusses the theoretical and managerial implications of these findings on network coopetition formation.
Schools and Natural Disaster Recovery: The Unique and Vital Role That Teachers and Education Professionals Play in Ensuring the Mental Health of Students Following Natural Disasters
Venue: Journal of Psychologists and Counsellors in Schools

There is growing evidence that children are vulnerable to poor psychological outcomes following exposure to a range of potentially traumatic events. Teachers are in a unique and well placed position to provide vital support to children following potentially traumatic events and to also provide a vital role in helping to identify children who may be experiencing ongoing psychosocial difficulties. We present a review of mental health trauma resources available for use in educational settings within Australia and New Zealand, with a primary focus on post disaster resources. We describe the design, development, and dissemination of our resources and training package, Childhood Trauma Reactions: A Guide for Educators from Preschool to Year 12, and present data on how these resources were received. Trauma informed practices within the school and classroom will enable better outcomes in the immediate post trauma environment and beyond for all children. Our model focuses on: (1) increasing awareness and understanding of children's post trauma reactions, (2) exploring effective strategies for teachers within the classroom, and (3) developing policy and procedures for the identification and referral of children who may be at risk. More funding is required to help distribute training and resources and to make mental health following trauma a higher priority.
Input shaping for PFC: how and why?

Predictive functional control (PFC) is a highly successful strategy within industry, but for cases with challenging dynamics the most effective tuning approaches are still an active research area. This paper shows how one can deploy some insights from the more traditional model predictive control literature in order to enable systematic tuning and in particular, to ensure that the key PFC tuning parameter, that is the desired closed loop time constant, is effective. In addition to enabling easier and more effective tuning, the proposed approach has the advantage of being simple to code and thus retaining the simplicity of implementation and tuning that is a key selling point of PFC. This paper focuses on design for open loop unstable and also processes with significant under damping in their open loop behaviour.
Coverage of ISO/IEC 12207 Software Lifecycle Process by a Simulation Based Serious Game
Venue: SPICE

Software process is a very important area of knowledge that supports software development. However, we can observe a lack of methods and tools that allow teaching software process in a highly practical way and attached to the software development learning. In this paper, we analyze the software lifecycle process groups of the ISO/IEC 12207 and the current application of serious games and gamification techniques within the software process education scope. Moreover, we propose a simulation based serious game for software project management teaching that can be used, at the same time, to educate learners in software process. The paper also maps the stages of the game lifecycle to the software lifecycle processes of the ISO/IEC 12207. Ten experts from the educational field have evaluated the idea of using the proposed serious game for software process education concluding that it helps learners acquire practical knowledge not only in the project management area but in the software process scope.
