Saving as an Image in Photoshop
Creating raster images and adjusting them on a layer-by-layer basis will allow you to save your images as a file format that you can then use in any number of other programs to further manipulate your images. After you save an image as a Photoshop file, you can use that file to work on anything from editing a single color to creating a complex, composite layer.
Creating a new image in Photoshop is simple:
1. Choose File⇒New.
You can also go to File⇒New. You will see the New dialog box, as shown in Figure 4-6.
2. Click to select the file format you’d like to save to and then choose the dimensions you’d like to create. Click Save.
Photoshop opens a new image in Photoshop. You can use the controls at the top of the dialog box to add any layers you may have loaded in Photoshop.
**Figure 4-6:** Select the file format you’d like to use and the size of the new image.
Creating a new document in Photoshop is different:

With the launch of Adobe Lightroom 5 Beta 1, we thought we’d take a look at the new features and changes in our favorite photo editing software.
Adobe Lightroom 5 has made a new start with its fifth version release. No longer part of the Creative Cloud, Lightroom is now free for independent software users, and it’s much more of a stand-alone app with a more simplified interface. The new program features a better file browser, better handling of catalogs, and powerful media analysis tools. The focus of Lightroom 5 is to make the photo editing process more intuitive with a consistent user experience that is easier to use.
Better file browser
Files can now be searched across the hard drive
Now when you open the editor or Lightroom, you can quickly get to your files by clicking File > Open. From there you can open a specific folder of files, a single file, or select files to open. When you open a folder, you’ll see files of all the types you’ve added to Lightroom appear in folders under the Photo Bin. You can also browse the image thumbnails in any folder. This can help you find the right file quickly.
A new View By column, shown below the Project Bin and Photo Bin, enables you to sort images by different factors, such as camera model, date added, resolution, copyright information, or categories in any custom collection. These can be toggled on or off as you prefer. Lightroom 5 now also supports sorting based on any of these groupings by right-clicking any view in the column and selecting Sort By.
When you are viewing your images in the browser, now you can drag and drop images from one workspace to another. You can also select files to automatically add them to a folder, such as one for sharing on Facebook.
Bringing more control to view modes
Lightroom 5 features the newly updated Grid, Picture View, and Details View modes. You can also create and save custom views within any of these modes.
Grid view presents a three-by-three grid of 3×3 preview thumbnails, showing 3 rows of 3 images. You can preview each image at 100%, 75%, 50%, 25%, or 0% opacity. This is great for seeing how a large image will look when you print it.
Picture View uses a photo viewer on a double screen to show the entire image displayed in one screen at 100%
Leaning Variational Inference – gwenz
Original paper [
Does this work in principle also for stochastic gradients?
If so, can we observe the same convergence to MAP solution as we do for
I think the MAP solution is overkill for this problem. I believe we are most
likely solving min f_t(x) + c ⟹ e_t
My point of view is if we end up solving a tractable problem, we are only
stopping at one point for sure. For that reason, we may see the same
convergence, but that convergence is not to the minimum of the problem in the
sense of infimum.
Anyone here tried this for inference over uncountable families of densities
No, though I’ve seen it used for this in previous work. I think a possible
use case would be: a finite mixture of Gaussians. And the paper makes clear
that this can converge to a MAP solution.
That’s actually very clever. What kind of convergence are we talking about?
Closeness in terms of KL divergence?
Does this work with densities, as in $\mathbb P(x)dx$?
Is it possible to define a function f(x) which on its own minimizes KL
divergence to an other random variable X?
Does this mean if I give you 1 trillion options to choose from, you would
choose “any” one of them? 🙂

Insights into the unfolding of a diverse set of G:C base-paired nucleic acids: GRAFFITI experiment.
This is the second of two in this issue highlighting the use of the GRAFFITI technique to study the folding of nucleic acids (NAs). In a previous report we showed that the GRAFFITI technique can be used to study the equilibrium unfolding of G:C base-paired DNA. Herein, the folding of a diverse array of unusual NAs is also reported. The unique ability of the GRAFFITI technique to probe the unfolding of DNA that has complex secondary structures, and its ability to sense the structural transitions of these novel NAs is examined. Surprisingly, all of the unusual NAs examined appear to be sensitive to the presence of H(2)O. The implications of the results are discussed in the context of the lack of structural diversity found in NAs that utilize the D-loop pathway.The role of the human bladder in the treatment of ureteral obstruction.
Renal function and morphology were assessed in a series of 13 patients treated by a new method for relief of ureteral obstruction. The technique is a transvesical ureterovesical anastomosis under continuous cystoscopic surveillance. The overall results showed improvement in renal function (assessed by urea excretion) in all cases and marked improvement in the urinary concentrating capacity (as assessed by the diuresis/ natriuresis ratio).; RUN: opt [#uses=1]
