This paper presents a video watermarking technology for broadcast monitoring. The technology has been developed at the Philips Research Laboratories in Eindhoven in the context of the European ESPRIT project VIVA (Visual Identity Veri cation Auditor). The aim of the VIVA project is to investigate and demonstrate a professional broadcast surveillance system. The key technology in the VIVA projec...

Dose per monitor unit in photon fields generated by clinical linear accelerators can be affected by the backscattered radiation into the monitor chamber from collimator jaws. Thus, it is necessary to account for the backscattered radiation in computing monitor unit setting for a treatment field. In this work, we investigated effects of the backscatter from collimator jaws based on Monte Carlo s...

This article presents an integrative review that aimed to analyze and synthesize the available scientific literature on rehabilitation of atrophic jaws without need for bone grafting, using All-on-Four technique. Searches were performed in databases selected studies published between 2018 2023. The included clinical studies, meta-analyses, systematic reviews addressed technique jaws. analyzed t...

Properly positioned synovial joints are crucial to coordinated skeletal movement. Despite their importance for skeletal development and function, the molecular mechanisms that underlie joint positioning are not well understood. We show that mice carrying an insertional mutation in a previously uncharacterized gene, which we have named Jaws (joints abnormal with splitting), die perinatally with ...

High-performance Web servers are essential to meet the growing demands of the Internet. Satisfying these demands requires a thorough understanding of the key factors that affect Web server performance. This paper provides three contributions to the design, implementation, and evaluation of high-performance Web servers. First, we report the results of a comprehensive empirical study of popular h...

Metastases or tumour to the jaws are rare and those to the temporomandibular joint (TMJ) are even rarer. The symptoms like preauricular pain, swelling and clicking are generally associated with TMJ disease. But the same symptoms are also found in tumours of the jaws or other diseases. We report on the case of a 48-year-old woman with a 12-year history of breast cancer who was referred to our de...

The ultrastructure of the jaws of Ordovician, Silurian, Permian and Recent Eunicida (Polychaeta) have been studied by transmission and scanning f'lectron microscopy. Primary and secondary zones have been distinguished in the ultrastructure of the jaws. The primary zone is formed of the pharyngeal cuticle containing an orthogonal network of collagen fibrils, while the secondary zone, underlying ...

In this paper we propose a computational grid platform called JaWS++ that seeks to harvest the power of idle pools of workstations connected through the Internet and integrate them in a grid computing platform for the execution of embarrassingly parallel computations. The computations are developed in the portable Java programming language and an API is provided for application development. JaW...
