Schema Mapper: A Visualization Tool for DL Integration

Schema mapping is a challenging problem. It has come to the fore in recent years; there are important applications like database schema integration and, more recently, digital library merging of heterogeneous data. Previous studies have approached the schema mapping process either from algorithmic or visualization perspectives, with few integrating both. With Schema Mapper we demonstrate a semi-automatic tool for schema integration that combines a novel visual interface with an algorithm-based recommendation engine. Schemas are visualized as hyperbolic trees (see Fig. 1), thus allowing more schema nodes to be displayed at one time. Matches to selections are recommended to the user, which makes the mapping operation easier and faster

Integration of Heterogeneous Digital Libraries with Semi-automatic Mapping and Browsing: From Formalization to Specification to Visualization

In this paper, we formalize the digital library (DL) integration problem and propose an overall approach based on the 5S framework. We apply 5S to domain-specific (archaeological) DLs, illustrating our solutions for key problems in DL integration. We use ETANA-DL as a case study to describe the process of semi-automatically generating a union catalog and a unified browsing service in an archaeological DL. A visual schema mapping tool is developed for union catalog creation. A pilot user study aids tool evaluation. Our approach is further validated through application of a general browsing component to two integrated DLs

Unilateral hemothorax in a 46 year old South Indian male due to a giant arteriovenous hemodialysis fistula: a case report

In a patient undergoing regular hemodialysis through an arteriovenous fistula access, pleural effusion is a known long term complication. However, a unilateral hemothorax is relatively uncommon. Here we report a 46 year old male, end-stage renal disease patient, on maintenance hemodialysis, who presented with a giant brachiocephalic AV fistula in his left arm and progressive breathlessness. Radiological imaging revealed a left sided pleural effusion. Ultrasound guided aspiration revealed a hemorrhagic pleural fluid. A Doppler study of the fistula revealed a high velocity blood flow through the fistula, thereby establishing the cause of the unilateral hemothorax. Ligation of the fistula resulted in complete resolution of the hemothorax. The other possible causes for hemothorax in a dialysis patient are also discussed in this case report

Sustainable Societal Empowerment through an Efficient Novel Paradigm on Industrial Internet of Things for Smart Medicare box

The main objective of this research is to develop a user-friendly medicine box for patients, ensuring they take the correct medication at the right time. The design allows for easy customization with minor modifications based on specific requirements. Caretakers or family members can enter and update tablet data in the medicine box, including expiry, count, and dosing schedule. Equipped with real-time clock data, the medicine box activates slot-specific LED lights and alarming sounds when it matches the designated medication schedule. These indicators turn off only when the patient takes the correct medicine from the respective slot, detected by ultrasonic sensors. The medicine box also features a reminder system, sending notifications via WhatsApp to the designated caretaker or family member to track medication adherence. Additionally, it includes a repeat button for patients to easily access and retake the previous dose. In case of emergencies, the medicine box is equipped with an emergency button, enabling patients to contact their caretakers or family members promptly. Furthermore, the medicine box automates the medicine ordering process by placing orders when any tablet is nearing its expiry or when the count falls below the minimum required level. Hence, these features ensure patient’s medication taken promptly

Hexagonal boron nitride for sulfur corrosion inhibition

Corrosion by sulfur compounds is a long-standing challenge in many engineering applications. Specifically, designing a coating that protects metals from both abiotic and biotic forms of sulfur corrosion remains an elusive goal. Here we report that atomically thin layers (∼4) of hexagonal boron nitride (hBN) act as a protective coating to inhibit corrosion of the underlying copper (Cu) surfaces (∼6–7-fold lower corrosion than bare Cu) in abiotic (sulfuric acid and sodium sulfide) and biotic (sulfate-reducing bacteria medium) environments. The corrosion resistance of hBN is attributed to its outstanding barrier properties to the corrosive species in diverse environments of sulfur compounds. Increasing the number of atomic layers did not necessarily improve the corrosion protection mechanisms. Instead, multilayers of hBN were found to upregulate the adhesion genes in Desulfovibrio alaskensis G20 cells, promote cell adhesion and biofilm growth, and lower the protection against biogenic sulfide attack when compared to the few layers of hBN. Our findings confirm hBN as the thinnest coating to resist diverse forms of sulfur corrosion
