TL;DR: A language to describe a mapping between an existing XML DTD and an existing relational schema is introduced and some of the interesting issues arising from such a mapping are discussed.
Abstract: XML is rapidly gaining momentum in e-commerce and Internet-based information exchange, where its simplicity and custom-defined tags make it usable as a semantics-preserving data exchange format. However, to realize this potential it is necessary to be able to extract structured data from XML documents and store it in a database, as well as to generate XML documents from data extracted from a database. Although many DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS- and platform-independent load/extract utility as well. In this paper, we describe such a utility that solves the following problems: (1) loading data from XML documents into relational tables with a known schema, (2) creating XML documents according to a known document type definition (DTD) from data extracted from a database, (3) generating relational schemas from XML DTDs for on-the-fly storage of XML documents, and (4) generating XML DTDs from relational schemas for on-the-fly extraction of relational data. We introduce a language to describe a mapping between an existing XML DTD and an existing relational schema and discuss some of the interesting issues arising from such a mapping.

TL;DR: In this paper, the production of mesons containing strange quarks and both singly and doubly strange baryons were measured at central rapidity in pp collisions at the ALICE experiment at the LHC.
Abstract: The production of mesons containing strange quarks ($\Kzs$, $\phi$) and both singly and doubly strange baryons ($\rmLambda$, $\rmAlambda$, and $\Xis$) are measured at central rapidity in pp collisions at $\sqrt{s}$ = 0.9 $\tev$ with the ALICE experiment at the LHC. The results are obtained from the analysis of about 250 k minimum bias events recorded in 2009. Measurements of yields (dN/dy) and transverse momentum spectra at central rapidities for inelastic pp collisions are presented. For mesons, we report yields ($ $) of $0.184 \pm 0.002 \stat \pm 0.006 \syst$ for $\Kzs$ and $0.021 \pm 0.004 \stat \pm 0.003 \syst$ for $\phi$. For baryons, we find $ = 0.048 \pm 0.001 \stat \pm 0.004 \syst$ for $\rmLambda$, $0.047 \pm 0.002 \stat \pm 0.005 \syst$ for $\rmAlambda$ and $0.0101 \pm 0.0020 \stat \pm 0.0009 \syst$ for $\Xis$. The results are also compared with predictions for identified particle spectra from QCD-inspired models and provide a baseline for comparisons with both future pp measurements at higher energies and heavy-ion collisions.

TL;DR: In this article, a framework for investigating the financial issues in logistics and supply chain management (SCM) has been proposed and shown that taking a supply chain perspective on financial issues offers great opportunities for SCM professionals.
Abstract: It is now accepted that logistics and supply chain management (SCM) have great potential for improving bottom line results. This paper proposes a framework for investigating the financial issues in logistics and SCM and shows that taking a supply chain perspective on financial issues offers great opportunities for SCM professionals. SCM can not only contribute to improvements in sales, cost of sales, and the invested capital, but also has the potential to improve the capital cost rate as a long neglected supply chain driver of shareholder value.

TL;DR: The design and construction of a simple, highly sensitive and selective nanofluidic sensing device, based on a single synthetic conical nanochannel for the sequence specific detection of single-stranded DNA oligonucleotides, and a control experiment indicated that the biosensor exhibits remarkable specificity toward a cDNA strand.
Abstract: Here we demonstrate the design and construction of a simple, highly sensitive and selective nanofluidic sensing device, based on a single synthetic conical nanochannel for the sequence specific detection of single-stranded DNA oligonucleotides. The biosensing performance of the device depends sensitively on the surface charge and chemical groups incorporated on the inner channel wall that act as binding sites for different analytes. Uncharged peptide nucleic acid (PNA) probes are covalently immobilized on the channel surface through carbodiimide coupling chemistry. This diminishes the channel surface charge, leading to a significant decrease in the rectified ion current flowing through the channel. The PNA-modified channel acts as a highly specific and selective device for the detection of a complementary single-stranded DNA sequence. Upon PNA/DNA hybridization, the channel surface charge density increased due to the presence of the negatively charged DNA strand. The changes in the surface charge-dependen...
