    1. I recommend the FireTray extension to you.https://addons.mozilla.org/en-US/firefox/addon/firetray/But some modification is necessary to make it installable for zotero 5.0:1. Download the the extension as an xpi file.2. Open the xpi file with archive manager.3. Edit the file install.rdf to make it installable for zotero 5.0. (Change the maxVerision from 4.* to 5.* in the Zotero section)4. Save the file and archive manager will ask you to update the file (choose update, of course).Install the modified xpi file and restart zotero if needed. Then you can change the preference of FileTray and check the option "start application hidden to tray".

      Worked with Zotero 5 on Ubuntu 18.04

    2. I like that the keyboard halves can get so far apart, but how can I attach the halves where I want them? Like on the side of an armchair? We had this exact use-case in mind when designing the stainless steel threaded inserts. There are four per halve, and allow you to put screws in from the back so you can mount your keyboard to almost anything.
    3. Do you plan to release a Bluetooth version or a version featuring a matrix/columnar layout? We’re considering it but not anytime soon.

    1. Please check out Software Carpentry as well. This is a great intro that covers not just programming and data analysis (R/Python), but a lot of crucial stuff that every bioinformatician should know but usually is not covered in courses, such as Unix shell Git and version control Unit testing SQL and databases Data management and provenance I also like A Quick Guide to Organizing A Computational Biology Project for organizational techniques that usually have to be learned by experience
    1. In my opinion if you can get enrolled into a degree program for systems biology then that would be best. However, if you are just exploring the field on your own I would recommend going through these resources.Video lectures by Uri AlonVideo Lectures by Jeff GorePrinciples of Synthetic Biology (at edx)Coursera specialization on systems biology.If you are looking for mathematical intensive start with first 2 and if you are looking for biologically intensive begin with last 2. Either way go through all 4 of them as they provide diverse perspective on systems biology which is very important. As you will move through these materials all the necessary supplementary information like books, papers and softwares will be informed within these materials itself.Hope this helps!
    1. Surface/Interior Depth-Cueing Depth cues can contribute to the three-dimensional quality of projection images by giving perspective to projected structures. The depth-cueing parameters determine whether projected points originating near the viewer appear brighter, while points further away are dimmed linearly with distance. The trade-off for this increased realism is that data points shown in a depth-cued image no longer possess accurate densitometric values. Two kinds of depth-cueing are available: Surface Depth-Cueing and Interior Depth-Cueing. Surface Depth-Cueing works only on nearest-point projections and the nearest-point component of other projections with opacity turned on. Interior Depth-Cueing works only on brightest-point projections. For both kinds, depth-cueing is turned off when set to zero (i.e.100% of intensity in back to 100% of intensity in front) and is on when set at 0 < n 100 (i.e.(100 − n)% of intensity in back to 100% intensity in front). Having independent depth-cueing for surface (nearest-point) and interior (brightest-point) allows for more visualization possibilities.
    2. Opacity Can be used to reveal hidden spatial relationships, especially on overlapping objects of different colors and dimensions. The (surface) Opacity parameter permits the display of weighted combinations of nearest-point projection with either of the other two methods, often giving the observer the ability to view inner structures through translucent outer surfaces. To enable this feature, set Opacity to a value greater than zero and select either Mean Value or Brightest Point projection.
    3. Interpolate Check Interpolate to generate a temporary z-scaled stack that is used to generate the projections. Z-scaling eliminates the gaps seen in projections of volumes with slice spacing greater than 1.0 pixels. This option is equivalent to using the Scale plugin from the TransformJ package to scale the stack in the z-dimension by the slice spacing (in pixels). This checkbox is ignored if the slice spacing is less than or equal to 1.0 pixels.
    4. Lower/Upper Transparency Bound Determine the transparency of structures in the volume. Projection calculations disregard points having values less than the lower threshold or greater than the upper threshold. Setting these thresholds permits making background points (those not belonging to any structure) invisible. By setting appropriate thresholds, you can strip away layers having reasonably uniform and unique intensity values and highlight (or make invisible) inner structures. Note that you can also use Image▷Adjust▷Threshold… [T]↑ to set the transparency bounds.
    1. By utilizing the Deeplearning4j library1 for model representation, learning and prediction, KNIME builds upon a well performing open source solution with a thriving community.
    2. It is especially thanks to the work of Yann LeCun and Yoshua Bengio (LeCun et al., 2015) that the application of deep neural networks has boomed in recent years. The technique, which utilizes neural networks with many layers and enhanced backpropagation algorithms for learning, was made possible through both new research and the ever increasing performance of computer chips.
    3. KNIME includes Python in various processing nodes for data processing, model learning and prediction, and the generation of visualizations.
    4. One of KNIME's strengths is its multitude of nodes for data analysis and machine learning. While its base configuration already offers a variety of algorithms for this task, the plugin system is the factor that enables third-party developers to easily integrate their tools and make them compatible with the output of each other.
    5. KNIME allows nodes from different research areas to be mixed to create truly cross-domain workflows.
    6. Apart from the free and open source KNIME Analytics Platform, KNIME also has commercial offerings. The KNIME server provides a platform for sharing workflows. It has a web interface and is connected to a KNIME instance for executing workflows remotely on demand or according to a schedule. Also commercially available are the Big Data Extensions and the KNIME Spark executor.
    7. old nodes in KNIME are never completely removed from the program but are deprecated so that workflows built with old versions can still be run and produce the same results years later.
    8. Passing the data between those tools often involves complex scripts for controlling data flow, data transformation, and statistical analysis. Such scripts are not only prone to be platform dependent, they also tend to grow as the experiment progresses and are seldomly well documented, a fact that hinders the reproducibility of the experiment. Workflow systems such as KNIME Analytics Platform aim to solve these problems by providing a platform for connecting tools graphically and guaranteeing the same results on different operating systems. As an open source software, KNIME allows scientists and programmers to provide their own extensions to the scientific community.
    9. SeqAn implements various applications that can be used for different tasks for example to map reads, apply read error correction, conduct protein searches, run variant detection and many more. However, analysts are not interested in a single execution of one tool but design and execute entire pipelines using different tools for different tasks contained in the pipeline. Often they also require some downstream analysis steps, e.g. computing some statistics, generating reports and so on. Hence it was desirable to add SeqAn applications to the KNIME workflow engine, which offers many additional analysis and data mining features.
    10. The Taverna workbench comes with an integration to myExperiment,13 a website for publishing and sharing scientific workflows. KNIME offers this integration as part of the de.NBI/CIBI plugin.14
    11. The tools presented above are all used in various areas of the life sciences, but their main task is the orchestration of external tools that exchange files with each other. Natively, KNIME goes a different way by encouraging a deep tool integration that is compatible with KNIME's table format. With this approach data are embedded into table cells allowing for easy tool interoperability without the need for file conversions.
    12. Orchestrating the execution of many command line tools is a task for Galaxy, while an analysis of life science data with subsequent statistical analysis and visualization is best carried out in KNIME or Orange. Orange with its “ad-hoc” execution of nodes caters to scientists doing quick analyses on small amounts of data, while KNIME is built from the ground up for large tables and images. Noteworthy is that none of the mentioned tools provide image processing capabilities as extensive as those of the KNIME Image Processing plugin (KNIP).
    13. Compared to other tools KNIME focuses on a deeper integration of tools and tries to manage the data that flows in the workflow by itself. Tools like Galaxy and Taverna, on the other hand, rather orchestrate command line tools that exchange files. Orange is very similar to KNIME in that it has extensive machine learning capabilities, but focuses more on the analysis of smaller data sets. We conclude that there are workflow tools for a variety of different use cases and that it is the scientists task to choose the tool that fits the problem at hand best. While there are certainly overlaps, each tool excels at its intended purpose.
    14. KNIME's network mining extension also has an integration with the open source bioinformatics software platform Cytoscape,9 which can be used to visualize molecular interaction networks and biological pathways. Installing the KNIME Connector plugin in Cytoscape enables users to exchange networks between the two tools.
    15. In conclusion, the KNIME Image Processing extensions not only enable scientists to easily mix-and-match image processing algorithms with tools from other domains (e.g. machine-learning), scripting languages (e.g. R or Python) or perform a cross-domain analysis using heterogenous data-types (e.g. molecules or sequences), they also open the doors for explorative design of bioimage analysis workflows and their application to process hundreds of thousands of images.
    16. In order to further foster this “write once, run anywhere” framework, several independent projects collaborated closely in order to create ImageJ-Ops, an extensible Java framework for image processing algorithms. ImageJ-Ops allows image processing algorithms to be used within a wide range of scientific applications, particularly KNIME and ImageJ and consequently, users need not choose between those applications, but can take advantage of both worlds seamlessly.
    17. Most notably, integrating with ImageJ2 and FIJI allows scientists to easily turn ImageJ2 plugins into KNIME nodes, without having to be able to script or program a single line of code

    1. The Heads Up Health web app is designed specifically to help you track ketones alongside all of your other vital health data.
    2. urine strips test for unused acetoacetate rather than the main ketone that our body does use, B-hydroxybutyrate.
    3. Why Measuring Ketones MattersBeing able to frequently and accurately measure the level of ketosis can be important for those following the ketogenic diet for clinical purposes as well as for overall health and performance. Due to individual variability in response to different types of food, having frequent feedback will aid individuals towards improving their understanding of how their body responds while increasing motivation and adherence.
    4. Zhou, W., Mukherjee, P., Kiebish, M. A., Markis, W. T., Mantis, J. G., & Seyfried, T. N. (2007). The calorically restricted ketogenic diet, an effective alternative therapy for malignant brain cancer. Nutrition & metabolism, 4(1), 5.
    5. More specific for those following a ketogenic diet, to date, six studies have compared breath acetone levels with blood b-hydroxybutyrate levels and have found a strong correlation (R2= 0.77) (8). One study in particular directly compared blood, breath, and urine samples of 12 healthy individuals undergoing an experimental protocol designed to induce a state of ketosis. The results demonstrated that plasma acetoacetate was best predicted by breath acetone (6). Therefore, it appears that breath acetone assessments are a fast and accurate way to test for the degree of ketosis.
    6. When following a ketogenic diet, acetyl-CoA is produced in the liver from the breakdown of fat and is used to produce acetoacetate, one of three ketone bodies.  From there, acetoacetate can be converted to the other two “ketone bodies”, b-hydroxybutyrate and acetone.  While b-hydroxybutyrate is tested via blood meters, acetone actually diffuses into the lungs and can be measured by testing exhaled breath (7)! Acetone is a byproduct of fat metabolism and is present in the breath of all humans but in different concentrations.
