    Gauge Theory of Elementary Particle Physics (2022)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: The aim of this book is to provide student and researcher with a practical introduction to some of the principal ideas in gauge theories and their applications to elementary particle physics. Elementary particle physics has made remarkable progress. We have a comprehensive theory of particle interactions. One can argue that it gives a complete and correct description of all non-gravitational physics. This theory is based on the principle of gauge symmetry. Strong, weak, and electromagnetic interactions are all gauge interactions. A knowledge of gauge theory is essential for anyone interested in modern high energy physics. Regardless of the ultimate correctness of every detail of this theory, it is the framework within which new theoretical and experimental advances will be interpreted in the foreseeable future.
    Keywords: Particle physics, relativistic quantum field theory, gauge symmetry, strong interactions, weak interactions, electromagnetic interactions, principles of locality, causality, renormalizability ; thema EDItEUR::P Mathematics and Science::PH Physics::PHN Nuclear physics

    Gauge theory of elementary particle physics (2024)

    Details
    Publication Date: 2024-04-11
    Description: Students of particle physics often find it difficult to locate resources to learn calculational techniques. Intermediate steps are not usually given in the research literature. To a certain extent, this is also the case even in some of the textbooks. In this book of worked problems we have made an effort to provide enough details so that a student starting in the field will understand the solution in each case. Our hope is that with this step-by-step guidance, students (after first attempting the solution themselves) can develop their skill, and confidence in their ability, to work out particle theory problems.

    A hybrid system applied to epidemic screening (2000)

    Notes: Although many knowledge-based systems (KBSs) focus on single-paradigm approaches to encoding knowledge (such as production rules), human experts rarely use a single type of knowledge to solve a real-world problem. A human expert usually combines a number of reasoning mechanisms. In recent years, rule-based reasoning (RBR), case-based reasoning (CBR) and model-based reasoning (MBR) have emerged as important and complementary reasoning methodologies in the intelligent systems area. For complex problem solving, it is useful to integrate RBR, CBR and MBR. In this paper, a hybrid epidemic screening KBS which integrates a deductive RBR system, an inductive CBR system and a quantitative MBR system is proposed. The system has been tested using real epidemic screening variables and data.

    Molecular population genetic analysis of the streptokinase gene of Streptococcus pyogenes: mosaic alleles generated by recombination (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Molecular microbiology 16 (1995), S. 0

    Notes: To understand the mechanisms governing molecular evolution of the streptokinase gene (skn), a 384 bp DNA fragment encoding two variable regions of the molecule was characterized in 47 isolates of Streptococcus pyogenes. The results reveal that alleles of the streptokinase gene have a mosaic structure, and provide strong evidence for intragenic recombination. Moreover, organisms that are well differentiated in overall chromosomal character have identical skn alleles, which suggests that horizontal gene transfer and recombination have participated in the evolution of this locus. No simple relationship between skn allele and serum opacity factor production or specific disease was identified. The predicted amino acid sequences of highly divergent skn alleles are strikingly similar in hydrophobicity and hydrophobicity profiles, distribution of amphipathic and flexible regions, surface probability plots, and antigenic indices, indicating that despite extensive nucleotide polymorphism in the two skn variable regions, selective pressure has constrained overall structural divergence. These results add to an important emerging theme that intragenic recombination plays a critical role in diversifying genes coding for streptococcal virulence factors.

    Response to culture aeration mediated by the nitrate and nitrite sensor NarQ of Escherichia coli K-12 (2003)

    Notes: Respiratory enzyme synthesis in enterobacteria is controlled in response to electron acceptor availability. The iron–sulphur protein Fnr and the sensor–regulator proteins ArcB–ArcA control respiratory gene transcription in response to oxygen and quinone pool redox status respectively. The sensor–regulator proteins NarX–NarL and NarQ–NarP control anaerobic respiratory gene expression in response to nitrate and nitrite. Our laboratory recently engineered the lac operon to replace the primary operator O1-lac with the NarL and NarP protein binding site from the nirB operon. Expression of the lacZ gene from this construct is repressed by nitrate in Nar+ strains. Here, we found that lacZ gene expression was repressed in aerated cultures of narQ+narX null strains. This repression was not observed in narX+narQ+ or narX+narQ null strains. Thus, the NarQ sensor responds to aeration as well as to nitrate and nitrite. The NarX and NarQ sensors are composed of three distinct modules: an amino-terminal sensory module, a carboxyl-terminal transmitter module and a central module of unknown function. Experiments with NarX–NarQ hybrid proteins suggest that the NarQ protein central module is necessary for response to aeration. The physiological significance of this additional sensory role for the NarQ sensor remains obscure.

    Property management in China: opportunities and problems (1997)

    Notes: The development of the real estate market in China has been well-documented, but one of the most interesting, yet chaotic issues in this market has not been fully covered. It is the problems and opportunities arising from the needs for the management of existing properties. Supply of prime office buildings in the major cities in China has been unprecedented owing to the strong demand from local and overseas companies. To preserve the investment value of the building, there is a great need for good management. However, those who have worked in a socialist country will understand that service industry is always the weakest point of the economy. It is, nevertheless, exactly for this reason that there is a great opportunity for established property management companies to expand their service not only in property management but also in the training of the new generation of local property managers in this potential market.

    Managing community in Hong Kong - the political economy perspective (2005)
    Bingley : Emerald
    Property management 23 (2005), S. 122-136

    Notes: Purpose - To examine how an incomplete and biased legal/regulatory framework governing the allocation of property rights within a residential community in Hong Kong blocks the natural choice of a market contractual arrangement for the governance of the community as well as the management services. Design/methodology/approach - This paper applies an institutional economic framework to examine the rationale of adopting different governance structures for different types of assets. A detailed case study is examined based on this framework and the governance structure of this community is analysed and the rationale behind the chosen structure is examined accordingly. Findings - It is found that a unified governance structure has been adopted in this community, not by the residents in the community, but by the developer who has a controlling share of property rights and vested interests on the undeveloped part of the community. Research limitations/implications - The case study, though detailed, limits to one community, which itself is very unique in the physical environment. In the future, different communities should be compared under different management models to examine the effect of developers' vested interests in the community and the governance structure, and how would a fair delineation mechanism of property rights will provide a more efficient management model for the community. Practical implications - It is suggested that an overall examination of the way property rights are delineated in Hong Kong is needed to protect the rights of individual property owners, so that a fairer and more efficient system can be in place. Originality/value - This paper argues that the choice of governance structure in a residential community under some special socio-political environments is also facilitated by the legal/regulatory framework delineating property rights.

    Privatising management services in subsidised housing in Hong Kong (2001)
    Bingley : Emerald
    Property management 19 (2001), S. 37-49 
    Details

    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Privatisation of services from the public sector is topical currently mainly because of the potential savings and efficiency to be gained. In the aspect of property management, the Hong Kong Housing Authority owns more than 600,000 units of public housing flats and the requirement for good and efficient property management services is enormous. The current policy of privatising these services to the private management agents has proved to be a correct direction in terms of retaining the growth of the public sector, and also improving the level of services to the tenants. While the privatisation scheme might bring in more opportunities for growth of the property management companies in the private sector, it is more important for the government to forge a proper transitional arrangement to switch to full private management in order not to endanger the already low morale in the public sector.

    The role of technology and quality on hospital financial performance: An exploratory analysis (2000)

    Notes: The stimulus for this research is that as US hospitals and health care organizations become more competitive, wise investments in technology and quality improvement are keys to financial success and survival. A structural equation model is hypothesized using the following five constructs: clinical technology; information technology; clinical quality; process quality; and hospital financial performance. No research to date has examined the relationships between the type of technology, the type of quality, and hospital financial performance. The general research hypothesis tested is that hospital technology directly drives (affects) quality and hospital financial performance. The results indicate that the type of hospital technology (clinical or information) drives different types of quality-related performance (clinical or process), and directly and indirectly affects hospital financial performance. The simple recursive model documented here is an important first step to defining more complete models that accurately predict hospital financial performance as a function of technology and quality investments and initiatives. The article concludes by summarizing results, discussing their implications, and proposing future research ideas.
