Abstract:
In the conceptual design of relational databases one of the main goals is to create a conceptual scheme, which minimize redundancies and eliminate deletion and addition anomalies, i.e. to create relation schemes in some good normal form. The study of relational databases has produced a host of normal forms: 2NF, 3NF, BCNF, Elementary-Key Normal Form, 4NF, Weak 4NF, PJ/NF, DK/NF, LTKNF, (3,3)NF, etc. There are two features which characterize these normal forms. First, they consider each relation separately. We believe that a normal form (which reflects the goodness of the conceptual design) sho

Abstract:
Levesque proposed a generalization of a database called a proper knowledge base (KB), which is equivalent to a possibly infinite consistent set of ground literals. In contrast to databases, proper KBs do not make the closed-world assumption and hence the entailment problem becomes undecidable. Levesque then proposed a limited but efficient inference method V for proper KBs, which is sound and, when the query is in a certain normal form, also logically complete. He conjectured that for every first-order query there is an equivalent one in normal form. In this note, we show that this conjecture

Abstract:
This paper compares different levels of database normalization process in terms of anomalies removal and storage reduction. Several databases have been normalized up to Third Normal Form (1NF, 2NF and 3NF) in order to investigate the influence of the normalization on the database performance. They are implemented separately with different database systems such as MS Access, SQL Server and Oracle. The percentage of storage reduction and data anomalies are investigated for every normal form and database system. The results show that the data storage is significantly reduced over unnormalized dat

Abstract:
Data restructuring is often an integral but non-trivial part of information processing, especially when the data structures are fairly complicated. This paper describes the underpinnings of a program, called the Restructurer, that relieves the user of the "thinking and coding" process normally associated with writing procedural programs for data restructuring. The process is accomplished by the Restructurer in two stages. In the first, the differences in the input and output data structures are recognized and the applicability of various transformation rules analyzed. The result is a plan for

This chapter examines the well-known Box-Cox method, which transforms a sample of non-normal observations into approximately normal form. Two non-standard aspects are highlighted. First, the likelihood of the transformed sample has an unbounded maximum, so that the maximum likelihood estimate is not consistent. The usually suggested remedy is to assume grouped data so that the sample becomes multinomial. An alternative method is described that uses a modified likelihood similar to the spacings function. This eliminates the infinite likelihood problem. The second problem is that the power trans

Their completeness is based on a new and crucial notion of inconsistency predicate, needed to ensure the usual closure properties of maximal consistent sets. As far as we know the calculi presented here are the first resolution calculi for this class of logics.

In the context of anomaly detection, the data mining technique of extracting association rules can be used to identify rare rules which represent infrequent situations.

The quasi-functional dependencies are usually inferred from the current instance of a database. However, in several applications, the database is not static, but new data are added or deleted conti

Abstract:
Review question / Objective: The aim of this review is two-fold: first, we sought to identify candidate biomarkers that could provide information on whether an individual with MDD would respond positively to common non-pharmacological treatments, and secondly, to conduct a meta-analysis to determine whether one form of common non-pharmacological treatment (namely CBT, tDCS and TMS) would produce better results over another in regards to its influence on biomarker levels. Information sources: The information sources used were: three online databases (PubMed, Scopus, and PsycINFO) to identify En

Abstract:
The objective of this research is to study the nature of the competition for cysteine (Cys), the first organic sulfur-containing compound, between its two main metabolites, glutathione (GSH) and methionine (Met). GSH plays a central role in protecting plants during various stresses, while Met, an essential amino acid, regulates essential processes and metabolites in plant cells through its metabolite S-adenosyl-Met. Our results, which are based on flux analysis and measurements of Met- metabolites, show that the flux towards Met synthesis is high during non-stress conditions, however the flux

Abstract:
Technology and innovation can mitigate and even prevent the damage caused by floods. A recent review by Kaundinya, Perné and Türkeli (2022) identified three main pathways to flood resilience: First, existing scientific knowledge and technology can be mobilised to create infrastructural innovations which can be either nature-based or non-nature based. The latter is more common and usually takes the form of the construction of dikes, dams and canals that directly reduce the probability of floods occurring. Large infrastructure projects tend to require significant financial and resource investmen

Abstract:
Scenario-based testing is a pillar of assessing the effectiveness of automated driving systems (ADSs). For data-driven scenario-based testing, representative traffic scenarios need to describe real road traffic situations in compressed form and, as such, cover normal driving along with critical and accident situations originating from different data sources. Nevertheless, in the choice of data sources, a conflict often arises between sample quality and depth of information. Police accident data (PD) covering accident situations, for example, represent a full survey and thus have high sample qu

Abstract:
Background: Genomics tools for enhancement of melon research, with an emphasis on fruit, were developed through a previous BARD project of the PIs (IS -333-02). These included the first public melon EST collection, a database to relay this information to the research community and a publicly available microarray. The current project (IS-3877- 06) aimed to apply these tools for identification of important genes for improvement of melon (Cucumis melo) fruit quality. Specifically, the research plans included expression analysis using the microarray and functional analyses of selected genes. The o

This rapid review synthesises evidence on the bilateral and multilateral donors promoting and protecting the human rights of LGBT+ people on a global scale. It focusses on those donors that have policies, implementation plans and programmes on LGBT+ rights. This review also examines the evidence on the impact of their work. The bilateral donors providing the most support for LGBT+ (Lesbian, Gay, Bisexual, Transgender, +) communities in 2017-18 are the Swedish International Development Cooperation Agency (Sida), UK Department for International Development (DFID), The Netherlands Development Coo

Abstract:
Our original objectives were to assess the unexplored dimension of alternative splicing as a source of genetic variation. In particular, we sought to initially establish an alternative splicing database for Arabidopsis, the only plant for which a near-complete genome has been assembled. Our goal was to then use the database, in part, to advance plant gene prediction programs that are currently a limiting factor in annotating genomic sequence data and thus will facilitate the exploitation of the ever increasing quantity of raw genomic data accumulating for plants. Additionally, the database was

Abstract:
The project exploits the use of Artificial Neural Networks (ANN) to describe infiltration, water, and solute distribution in the soil during irrigation. It provides a method of simulating water and solute movement in the subsurface which, in principle, is different and has some advantages over the more common approach of numerical modeling of flow and transport equations. The five objectives were (i) Numerically develop a database for the prediction of water and solute distribution for irrigation; (ii) Develop predictive models using ANN; (iii) Develop an experimental (laboratory) database of
