I'm trying to fix up an original Mac Cinema Display and sure could use a schematic.

The 700mm ccfl tubes are very dark at the ends, probably all worn out.

I can easily replace them with a strip of white LED's, BUT the dang smart ccfl power supply detect a lack of a load and signals no-go and blinks the power button.

It sure would help to have a schematic or service manual (hope-hope). Any pointers appreciated.

As a last resort I could hang load resistors where the ccfls were but that's kinda pins my kludge meter.

TheStreet.com's Jim Cramer thinks the estimates cuts for Research in Motion signal the end of its leadership position...

i(18 Nov 2008)/ibr /br /We introduce a quantitative measure of the capacity of a small biological network to evolve. We apply our measure to a stochastic description of the experimental setup of Guet et al. (Science 296:1466, 2002), treating chemical inducers as functional inputs to biochemical networks and the expression of a reporter gene as the functional output. We take an information-theoretic approach, allowing the system to set parameters that optimize signal processing ability, thus enumerating each network's highest-fidelity functions. We find that all networks studied are highly evolvable by our measure, meaning that change in function has little dependence on change in parameters. Moreover, we find that each network's functions are connected by paths in the parameter space along which information is not significantly lowered, meaning a network may continuously change its functionality without losing it along the way. This property further underscores the evolvability of the networks.br /iAndrew Mugler, Etay Ziv, Ilya Nemenman, Chris Wiggins/i

i(1 Dec 2008)/ibr /br /Bifurcations leading to complex dynamical behaviour of non-linear systems are often encountered when the characteristics of feedback circuits in the system are varied. In systems with many unknown or varying parameters, it is an interesting, but difficult problem to find parameter values for which specific bifurcations occur. In this paper, we develop a loop breaking approach to evaluate the influence of parameter values on feedback circuit characteristics. This approach allows a theoretical classification of feedback circuit characteristics related to possible bifurcations in the system. Based on the theoretical results, a numerical algorithm for bifurcation search in a possibly high-dimensional parameter space is developed. The application of the proposed algorithm is illustrated by searching for a Hopf bifurcation in a model of the mitogen activated protein kinase (MAPK) cascade, which is a classical example for biochemical signal transduction.br /iSteffen Waldherr, Frank Allg#38;#xf6;wer/i

iBMC Bioinformatics, Vol. 9 (28 November 2008), 504./ibr /br /Background: Liquid chromatography coupled to mass spectrometry (LC/MS) is an important analytical technology for e.g. metabolomics experiments. Determining the boundaries, centres and intensities of the two-dimensional signals in the LC/MS raw data is called feature detection. For the subsequent analysis of complex samples such as plant extracts, which may contain hundreds of compounds, corresponding to thousands of features - a reliable feature detection is mandatory. Results: We developed a new feature detection algorithm "centWave" for high-resolution LC/MS data sets, which collects regions of interest (partial mass traces) in the raw-data, and applies continuous wavelet transformation and optionally Gauss-fitting in the chromatographic domain. We evaluated our feature detection algorithm on dilution series and mixtures of seed and leaf extracts, and estimated recall, precision and F-score of seed and leaf specific features in two experiments of different complexity. Conclusions: The new feature detection algorithm meets the requirements of current metabolomics experiments. centWave can detect close-by and partially overlapping features and has the highest overall recall and precision values compared to the other algorithms, matchedFilter (the original algorithm of XCMS) and the centroidPicker from MZmine. The centWave algorithm was integrated into the Bioconductor R-package XCMS and is available from http://www.bioconductor.org/.br /iRalf, Steffen Neumann/i

iJ. Neurosci., Vol. 25, No. 26. (29 June 2005), pp. 6137-6144./ibr /br /We studied the temporal coding properties of identified interneurons in the auditory system of crickets, using information theory as an analytical tool. The ascending neuron 1 (AN1), which is tuned to the dominant carrier frequency (CF) of cricket songs, selectively codes the limited range of amplitude modulation (AM) frequencies that occur in these signals. AN2, which is most sensitive to the ultrasonic frequencies that occur in echolocation calls of insectivorous bats, codes a broader range of AM frequencies, as occur in bat calls. A third neuron, omega neuron 1 (ON1), which is dually tuned to both ranges of carrier frequency, was shown previously to have CF-specific coding properties, allowing it to represent accurately the differing temporal structures of both cricket songs and bat calls. ON1 is a source of contralateral inhibition to AN1 and AN2, enhancing binaural contrast and facilitating sound localization. We used dichotic stimulation to examine the importance of the temporal structure of contralateral inhibition for enhancing binaural contrast. Contralateral inhibition degrades the coding of temporal pattern by AN1 and AN2, but only if the temporal pattern of inhibitory input matches that of excitation. Firing rate is also decreased most strongly by temporally matched contralateral inhibition. This is apparent for AN1 in its mean firing rate; for AN2, high-frequency firing is selectively suppressed. Our results show that the CF-specific coding properties of ON1 allow this single neuron to enhance effectively localization cues for both cricket-like and bat-like acoustic signals. 10.1523/JNEUROSCI.0646-05.2005br /iGary Marsat, Gerald Pollack/i

I've seen a thread regarding Google Maps, but just another thread to ask a specific question.

Due to the fact the iPod Touch 2G doesn't have GPS, it relies on Wifi. However, when I connect to mine, it is unable to determine my current location. I read somewhere that this is due to the lack of other Wifi signals and being unable to "triangulate" the location.

Someone suggested going to an area with many Wifi signals such as a city, but I'm wondering if anyone in Australia has been able to do that. I've tried it yet I'm still unable to determine my location.

Any ideas/solutions?

Film d'horreur indépendant complètement terrifiant et original par son montage, The Signal bénéficiera d'une sortie Blu-Ray Disc française...

I am having trouble with my Time Capsule's wireless range. I am not a networking expert by any means. I own an old building that is 4 stories connected by stairs with thick walls. All the rooms ethernet cables converge in a cubby on the 3rd floor. I placed my Time Capsule in the cubby, but I couldn't receive a wireless signal from the 1st floor. This is ironic because I have an old Netgear G router that sends signals throughout all 4 floors. So I bought an Airport Express to extend my network wirelessly, but the signal has been unstable perhaps because the Time Capsule's wireless signal is too weak. So I want to connect the Airport Express on the 1st floor using the Ethernet link from the 3rd floor Time Capsule which is my main router. From my research, I discovered about WDS networks, which I believe you have to use in order to create a network with multiple Apple base stations linked through ethernet.

I called Applecare who told me:
-To connect from Time Capsule to Airport Express using Ethernet, must use WDS network. Setup Airport Express as Relay, NOT Remote.
-Relay- Direct ethernet connection from Time Capsule to Airport Express, then wireless connection from Airport Express to Macbook.
-Remote- Wireless signal from Time Capsule to Airport Express, then direct Ethernet connection from Airport Express to Macbook

I have several questions for you wise people out there:

1. To extend the Time Capsule wireless network using the Airport Express, but connected directly via ethernet, do I need to setup a WDS network?

2. I prefer to just use the simple Apple settings "extend network wirelessly". Will this setting only boost a wireless signal received from the Time Capsule? Can it not extend a wireless signal sent directly from Ethernet?

3. I'm considering getting a Quickertek Triband antenna to place outside the cubby. Anyone have any experience with Airport external antennas?:

iBMC Bioinformatics, Vol. 9, No. 1. (2008)/ibr /br /BACKGROUND:In gene expression studies a key role is played by the so called “pre-processing”, a series of steps designed to extract the signal and account for the sources of variability due to the technology used rather than to biological differences between the RNA samples. At the moment there is no commonly agreed gold standard pre-processing method and each researcher has the responsibility to choose one method, incurring the risk of false positive and false negative features arising from the particular method chosen.RESULTS:We propose a Bayesian calibration model that makes use of the information provided by several pre-processing methods and we show that this model gives a better assessment of the `true' unknown differential expression between two conditions. We demonstrate how to estimate the posterior distribution of the differential expression values of interest from the combined information.CONCLUSIONS:On simulated data and on the spike-in Latin Square dataset from Affymetrix the Bayesian calibration model proves to have more power than each pre-processing method. Its biological interest is demonstrated through an experimental example on publicly available data.br /iMarta Blangiardo, Sylvia Richardson/i

Publication Date: 2008 Nov 29 PMID: 19040754br/Authors: Foley, J. W. - Katagiri, F.br/Journal: BMC Bioinformaticsbr/br/ABSTRACT: BACKGROUND: Large biological data sets, such as expression profiles, benefit from reduction of random noise. Principal component (PC) analysis has been used for this purpose, but it tends to remove small features as well as random noise. RESULTS: We interpreted the PCs as a mere signal-rich coordinate system and sorted the squared PC-coordinates of each row in descending order. The sorted squared PC-coordinates were compared with the distribution of the ordered squared random noise, and PC-coordinates for insignificant contributions were treated as random noise and nullified. The processed data were transformed back to the initial coordinates as noise-reduced data. To increase the sensitivity of signal capture and reduce the effects of stochastic noise, this procedure was applied to multiple small subsets of rows randomly sampled from a large data set, and the results corresponding to each row of the data set from multiple subsets were averaged. We call this procedure Row-specific, Sorted PRincipal component-guided Noise Reduction (RSPR-NR). Robust performance of RSPR-NR, measured by noise reduction and retention of small features, was demonstrated using simulated data sets. Furthermore, when applied to an actual expression profile data set, RSPR-NR preferentially increased the correlations between genes that share the same Gene Ontology terms, strongly suggesting reduction of random noise in the data set. CONCLUSIONS: RSPR-NR is a robust random noise reduction method that retains small features well. It should be useful in improving the quality of large biological data sets.br/br/post to: a href = http://www.citeulike.org/posturl?url=http%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fentrez%2Fquery.fcgi%3Fcmd%3DRetrieve%26db%3DPubMed%26dopt%3DAbstract%26list_uids%3D19040754title=Entrez+PubmedCiteULike/a
