This article describes a software named KnotPortal for visualization of branched covers knots based on an idea by Bill Thurston to view knot as portal other universes. Our implementation allows users explore these knotted portals either screen or in virtual reality using head-mounted device with room-tracking. not only see glued different worlds, but experience them being able walk through the ...

We address the notorious metastability of Standard Model (SM) and promote it to a model building task: What are new ingredients required stabilize SM up Planck scale without encountering sub-Planckian Landau poles? Using extended by vectorlike fermions, we chart out corresponding landscape Higgs stability. find that gauge portal mechanism, triggered charge carriers, opens sizable room for stabi...

Arthrodesis of the first metatarsophalangeal joint is indicated for severe hallux valgus deformity. Open arthrodesis requires extensive soft-tissue dissection. Recently, a technique arthroscopic in deformity has been reported. This approach includes endoscopic lateral release via plantar and toe web portals, followed by medial dorsolateral portals. Endoscopic can convert fixed into flexible one...

Organizations use corporate portals to share, save, and retrieve knowledge for all of their clients, partners, employees, suppliers. Corporate help businesses become more inventive competitive. E-Portals are created using web internet technologies accessed by a browser on computer system contribute, retrieve, or update knowledge. This essay examines the effects e-portals, novel method connectin...

BACKGROUND Modern information technology is changing and provides new challenges to health care. The emergence of the Internet and the electronic health record (EHR) has brought new opportunities for patients to play a more active role in his/her care. Although in many countries patients have the right to access their clinical information, access to clinical records electronically is not common...

BACKGROUND The Internet offers a seemingly endless amount of health information of varying quality. Health portals, which provide entry points to quality-controlled collections of websites, have been hailed as a solution to this problem. The objective of this study is to assess the extent to which government-run health portals provide access to relevant, valid and understandable information abo...

This paper describes the evolution of the Portals message passing architecture and programming interface from its initial development on tightly-coupled massively parallel platforms to the current implementation running on a 1792-node commodity PC Linux cluster. Portals provides the basic building blocks needed for higher-level protocols to implement scalable, low-overhead communication. Portal...

In this paper we discuss the benefits of semantic information portals. We argue that creating semantic information portals using Semantic Web technologies pays off right from the beginning: The possibility to reason about the (semantically annotated) Web resources allows for realizing personalization functionality which otherwise, i.e. compared to conventional portals, requires additional overh...

Evaluation of web portals is an important topic in web engineering. The satisfaction of users is a primary goal for actors involved with the development and operation of a web portal. Different users can not be treated as the same because people have different drives, abilities, and personalities. There are four basic types of personality (temperaments): Choleric, Sanguine, Melancholy, and Phle...
