The limited screen size and resolution of current mobile devices can still be problematic for map, multimedia and browsing applications. In this paper we present Touch & Interact: an interaction technique in which a mobile phone is able to touch a display, at any position, to perform selections. Through the combination of the output capabilities of the(More)
Regions of the short arm of chromosome 8 are deleted frequently in a range of solid tumors, indicating that tumor suppressor genes reside at these loci. In this study, we have examined the properties of the Wnt signaling antagonist secreted frizzled-related protein (sFRP) 1 as a candidate for this role at c8p11.2. An initial survey of 10 colorectal tumors,(More)
Conditional expression of hairpin constructs in Drosophila is a powerful method to disrupt the activity of single genes with a spatial and temporal resolution that is impossible, or exceedingly difficult, using classical genetic methods. We previously described a method (Ni et al. 2008) whereby RNAi constructs are targeted into the genome by the(More)
OBJECTIVE To investigate the relationship between sense of coherence (SOC) and oral health. It was hypothesised that subjects with better oral health status and better oral health-related behaviours have higher levels of SOC. METHODS A cross-sectional study was conducted in Goiânia-GO, Middle-West Brazil, on a sample of 664 15-year-olds randomly selected(More)
Exchanging data between a mobile phone and a computer such as a laptop is still a very cumbersome process. This paper presents two different techniques, <i>touch &amp; connect</i> and <i>touch & select</i>, designed help to overcome this problem and facilitate and speed up spontaneous interactions between such devices. Using <i>touch & connect</i>, the user(More)
We introduce NaviRadar: an interaction technique for mobile phones that uses a radar metaphor in order to communicate the user's correct direction for crossings along a desired route. A radar sweep rotates clockwise and tactile feedback is provided where each sweep distinctly conveys the user's current direction and the direction in which the user must(More)
This paper reports on a development framework, two prototypes, and a comparative study in the area of multi-tag Near-Field Communication (NFC) interaction. By combining NFC with static and dynamic displays, such as posters and projections, services are made more visible and allow users to interact with them easily by interacting directly with the display(More)
Evidence for the molecular basis of colorectal cancer comes from genetic analysis of tissues either from patients with a family history of the disease or from patients with sporadic adenomatous colorectal polyps or extensive ulcerative colitis. The traditional view is that background rates of genetic mutation, combined with several rounds of clonal(More)
BACKGROUND AND AIMS C-myc over expression is implicated in malignancy although to date this has not been studied in Barrett's metaplasia. We sought to determine c-myc expression in the malignant progression of Barrett's metaplasia and whether it may be induced by bile acids seen in gastro-oesophageal refluxate. METHODS C-myc protein and mRNA levels were(More)
