Upper left panel, Electrical signals are recorded from a Xenopus oocyte expressing the circadian photoreceptor melanopsin in response to illumination with blue light. Upper right panel, Photocurrent recorded from an oocyte expressing melanopsin and the TRPC3 ion channel in response to illumination at various wavelengths. Peak activation of melanopsin signaling occurs at about 470 nm, which corr...
This preliminary study investigates how participants make sense of search results, web-pages and documents when they use web-based environments. From a sensemaking perspective, it bridges across previous information seeking studies, which focused on specific aspects of information interaction such as search or information relevance judgments. This study corroborates some of those previous obser...
Example 3.1.4. Let G be a directed graph and suppose vertex v has indegree k and outdegree `, i. e., k edges end at v and ` edges start at v. Each of these k+ ` edges will represent a vertex in the directed line graph ~ L(G), and since the terminus of each of the former k edges is the initial point of each of the latter `, in the line graph each of the former will have an edge directing to each...
The Ensembl (http://www.ensembl.org/) project provides a comprehensive and integrated source of annotation of chordate genome sequences. Over the past year the number of genomes available from Ensembl has increased from 15 to 33, with the addition of sites for the mammalian genomes of elephant, rabbit, armadillo, tenrec, platypus, pig, cat, bush baby, common shrew, microbat and european hedgeho...
Long term care is a vital public policy issue in Canada, as it is in all developed countries (OECD 2005). Expanding life spans, ageing populations and increased healthcare expectations challenge governments two ways. Seniors tend to require more social spending, especially for health and home care. Further, this group tends to be less economically productive. Therefore societies must learn how ...
The first speaker was Jonathan Kew, who related the history and current status of X E TEX. After its initial appearance in the spring of 2004 on MacOSX, a version supporting OpenType fonts appeared the following year. X E TEX for Linux was announced at BachoTEX 2006, and was quickly followed in June by a version for Windows. This year marked a milestone for the X E TEX project, in that it becam...
Introduction Interpreting quantitative EEG results and correlating symptoms can be difficult when there is more than a single contributor or aberrant finding. The clinician may be forced to make decisions with their best estimate of where to begin with neurofeedback interventions. In these cases there are many sites which appear to be equally contributing to the cause leaving the clinician with...
Oscilloscopes have been used extensively to analyze the jitter performance of serial data links providing estimates (measurements) of total jitter as well as its “random” and “deterministic” parts. Higher speed serial data signals containing jitter from sources such as crosstalk and multi-Gaussian random noise can cause traditional oscilloscope-based methods to greatly over or under estimate th...
Author identification can be seen as a single-label multi-class text categorization problem. Very often, there are extremely few training texts at least for some of the candidate authors or there is a significant variation in the text-length among the available training texts of the candidate authors. Moreover, in this task usually there is no similarity between the distribution of training and...
