"The way to get a big idea to appear in your head is not to hunt for big ideas, but to put in a lot of time on work that interest you, and in the process keep your mind open enough that a big idea can take roost."

[Bloomberg] China is facing longest deflation streak since Mao era in 1960s:
"Deflation can be a silent killer of commerce and consumption over the long haul. Even though cheaper goods may seem appealing, the danger is people could delay purchases because they expect prices to fall further.
Weaker consumer spending would then erode income for businesses, which in turn would reduce hiring and investment — resulting in a vicious cycle."
"Well, screw that. Yes, you have to be clever, but if you have good taste in problems, an ability to forge intellectual connections, an eye for untapped opportunities, drive, and yes, a willingness to work hard, you can have major impacts on the field."

Chinese sharing platform RedNote, also known as Xiaohongshu in China, has emerged as the biggest winner following the upcoming ban of TikTok in the U.S., which is set to take effect on January 19. A wave of users, often calling themselves "TikTok refugees", has already begun transitioning to the app, seeking an alternative platform to share and connect. This surge in users propelled the app to become the #1 free app downloaded on the Apple App Store. However, while it remains uncertain whether RedNote will become the go-to platform for displaced TikTok creators, its meteoric rise underscores the shifting landscape of social media amid ongoing geopolitical tensions.
In addition to its international success, RedNote has been gaining traction domestically in China, gradually replacing the search engine Baidu for many users. Increasingly, people are turning to RedNote as their primary tool for finding information they need, signaling a notable shift in user preferences.
Having just completed the abstract submission for ISMRM 2025, I found myself spending a lot of time perfecting the figures. To save time next year and help others in a similar position, I thought it would be helpful to compile some tips on creating clear, effective figures for ISMRM submissions or publications.
To start, it's important to understand the differences between common image formats. ISMRM allows images to be submitted in PNG or JPEG formats, with GIF permitted for animated display. While I'm not an expert on the topic, the key point is that JPEG uses lossy compression, meaning it reduces file size by discarding some image data, whereas PNG is a lossless format that retains all image details. Since JPEG files are typically smaller, they're ideal for meeting ISMRM's 2MB file size limit, making JPEG my go-to choice.
Returning to MATLAB. As for figure creating, two commonlly-used functions are: plot & imshow. You can save these figures manually or automate the process with the print function. However, the default properties for both plot & imshow aren't typically optimized for publication-quality images. MATLAB offers a variety of customization options through Axes Properties and Figure Properties, which can be adjusted with the set using axie handle gca and figure handle gcf.
For example, if you want to set the font size to 16 and line weight to 2 for the axis, you can use the command: set(gca, 'FontSize', 16, 'LineWeight', 2). If you need an exact figure size without resizing it in other software, use: set(gcf, 'Position', [10, 10, 500, 1000]), where Position property is a vector [left, bottom, width, height] (refer to Figure Properties for more details). For a black background, you can set: set(gcf, 'Color', 'k').
Additionally, nexttile function is a good alternative to the subplot function because it can control the subplot spacing. A general usage example would look like:
figre(1) t = tiledlayout(2,2, 'TileSpacing', 'compact') nexttile, plot(x1, y1); nexttile, plot(x2, y2); nexttile, plot(x3, y3); nexttile, plot(x4, y4);
For the function imshow, a helpful setting is imshow(abs(YourImage), [], 'border', 'tight'), which removing unnecessary margins around the saved images, saving time on cropping. The montage function is also useful, allowing you to combine images of different sizes into a single display. I often use it to combine a series of images and their zoomed-in details.
Regarding GIF creating, I wrote a function to create GIF format:
function saveGIF(im3d, framerate, dir) % write the mat file to GIF format % Only support 3D images % input: % im3d : size = [width, hight, time]. % framerate: expected frame rate of created GIF. % dir : ../../XXX.gif. im3d = abs(im3d); for i = 1:size(im3d,3) [A, map] = gray2ind(im3d(:,:,i), 256); if i == 1 imwrite(A, map, dir, "gif", ... "LoopCount", Inf, "DelayTime", framerate); else imwrite(A, map, dir, "gif", ... "WriteMode", "append", "DelayTime", framerate); end end
You can edit GIF using ezgif, a clean, and efficient website for GIF editing.
