![]() The classic text on eye physiology put forward the theory, generally accepted, that slit-shaped pupils allow for different musculature and a greater range in the amount of light entering the eye.įor example, the vertical slits of domestic cats and geckos undergo a 135- and 300-fold change in area between constricted and dilated states, while humans’ circular pupils undergo a mere 15-fold change. This current research builds upon the foundation set by the late Gordon Walls, a UC Berkeley professor of optometry who published The Vertebrate Eye and Its Adaptive Radiation in 1942. The findings were published today in the journal Science Advances. The study, led by vision scientist Martin Banks, a UC Berkeley professor of optometry, in collaboration with the United Kingdom’s Durham University, presents a new hypothesis as to why pupils are shaped and oriented the way they are. Circular pupils were linked to “active foragers,” or animals that chase down their prey. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. Why do some animals have horizontally elongated pupils? (Video produced by Gordon Love, Durham University, in collaboration with UC Berkeley)Īn analysis of 214 species of land animals shows that a creature’s ecological niche is a strong predictor of pupil shape. Behavioral Ecology, 15(6), 1003–1010.While the eyes may be a window into one’s soul, new research led by UC Berkeley scientists suggests that the pupils could also reveal whether one is hunter or hunted.

![]() One of the pieces I really enjoy about the cards is how they have lots of throwback mechanics that we don’t often see in Magic anymore. We knew we had a new opportunity here to create cards that would really appeal to our Commander players. Turian: For these four characters, there initially was some thought that the cards in the product would pair directly with our The Lord of the Rings Commander product but due to other constraints like design space, we moved away from that. These boxes almost feel like little “build-your-own Commander precon” kits: each one has that multicolored legendary, some brand new cards that support their mechanics, and some packs to get your collection going. Another factor playing into our selection was making sure that there was diversity, even with just four Scene Boxes to highlight characters, we wanted to make sure that all of our fans felt included as much as possible. ![]() For Gandalf specifically, it helps that he was a powerful wizard, which opens up itself to lots of fun card designs, and that his character evolves significantly throughout The Lord of the Rings. The combination of being prominently featured in the novel really helps when we choose Gandalf, for instance, because even though we had done a number of other Gandalf cards, being able to find a place in his development that we wanted to capture was key. We needed to make sure that there was more design space available for the character. For one, we took at the characters of The Lord of the Rings that were fan favorites and that was a great starting point. Turian: For each product we took a number of factors into account as we went about choosing what characters to feature. How did you land on these four characters? So for instance, in the Gandalf in the Pelennor Fields Scene box, the Gandalf that you receive is white, blue and red so we wanted to make sure each card in his box a one or more of those colors. It became clear that we would have more success by choosing new color options for each Scene Box and building the cards that we made around the central character of the box. The challenge became with so much freedom, how do we best capture the spirit of the characters and their setting? Early on, we discussed closely tying the characters to cards that were made in the June release. Turian: One of the great things about this release is that we were creating brand new cards for these scenes, so yes, that let us customize the cards and their abilities to best fit the scene. Did that give you more freedom to design them or depict characters and events exactly how you wanted? The previous scenes were more restricted since they had to use cards from the main set, while all of these cards are brand new. You can read on to see our full interview with Mike Turian and Sarah Wassell, or if you want to even more fancy foiled unboxings, we opened up the shiny Compleat Edition from Magic’s Phyrexia: All Will Be One set earlier this year Magic’s Lord of the Rings set has already been making headlines with special serialiazed cards: its one-of-a-kind One Ring card was sold to Post Malone for a whopping $2 million. “It’s incredible, the far-reaching effect of LTR on fantasy and art and music,” says Art Director Sarah Wasell, “and we loved taking the space to honor one of the more surprising areas of Tolkien fandom through these ‘band posters.’” In addition to the four scene boxes, Wizards of the Coast will also be rolling out new Special Edition Collector Boosters for Tales of Middle-Earth around the same time, which will potentially include any of twenty cards from the original set in a brand new 60s rock poster art style - as well as rare serialized versions of these cards numbered up through 100. “Another factor playing into our selection was making sure that there was diversity, even with just four Scene Boxes to highlight characters, we wanted to make sure that all of our fans felt included as much as possible.” “For Gandalf specifically, it helps that he was a powerful wizard, which opens up itself to lots of fun card designs, and that his character evolves significantly throughout The Lord of the Rings,” Turian explains. (I may have gotten an unfair headstart, but Galadriel in particular was so cool to me that I’ve already built a Commander deck around her.) But while Turian says they did initially consider pairing these scenes directly with the previous LOTR commander products from earlier this year, they decided to make them stand on their own to allow for more design space. Because each box has a legendary character and some new cards that go with it, they almost feel like little commander precons without any of the reprints, waiting to be fleshed out however you see fit. ![]() Players can pick one of these classes to play.

Go ahead and accept that and then hit the plus key. Gleek can often predict what you want to type, so it will offer to complete the arrow. To show this interaction, just type a hyphen, then the word “visits”, and then another hyphen. Now the user needs to start interacting with the other objects in the system by visiting the “Login page”. Just type the word “User” in the code field and Gleek will draw a rectangle with rounded edges to represent an object. Right, let’s put our sequence diagrams to good use and model a login page for a website! First, we need to head over to the Gleek.io app and select “sequence diagram” from the dropdown menu. Step-by-step guide to creating a login system sequence diagram ![]() In the sequence diagram, this is represented by an alt, or alternative, operator that creates a frame around part of the sequence showing the choice between accepting or rejecting the user login information.

If not, you will usually get a response telling you to try again.Ĭheck out our latest how-to article on a Sequence diagram for Microservices using Gleek AI chat. If everything is correct, you get cleared to enter the site. The server will then run some complicated algorithms to check whether you have submitted the correct password. You enter your data and submit the form, and this is when the sequence diagram kicks in and shows how useful it can be.Īssuming you have filled in both the username/email address and password, the server will first check that the username exists in the system. This is often just your email address and a password. Once the page has loaded, you’re usually presented with a form that allows you to enter your credentials, or in other words the information that you used to sign up for the site. So what actually happens when you arrive on the login page for your favorite website? That’s exactly what a sequence diagram is designed to show. Behind the scenes, any login page involves messages being sent back and forth, objects being activated, and responding with data, and it happens over a discrete period of time. How can you create a sequence diagram for a login system?Ī great example of sequence diagrams is a user login system. For much more detail, you should check out our sequence diagram page on Gleek. That gives you an overview of what to expect from a sequence diagram. The arrows are usually labeled so that you can easily understand the content of the message. Messages can be sent back and forth, from left to right, and the arrow shows which is the receiver and which the sender of the message. These messages are represented by a line with an arrow. Each object can also have an activation bar on its lifeline that will show when it is active in the system and accepting or processing information from another object.Īctivity in the system is shown by messages that pass between the objects. These lifelines are shown by parallel vertical lines that can never overlap. Each object has a lifeline that represents its existence in time.

If, for example, you wanted to share 10 images with a friend, you would need to send them 10 separate JPGs, which might be inconvenient or even impossible, depending on the situation. While JPG images are great, they cannot contain multiple pages of images. Like JPGs, PDFs are terrific for sharing on the internet because they always look the same regardless of device. It can also have hyperlinks and even images. A PDF is a document file that usually contains pages of text.

Most web browsers, like both Chrome and Firefox, can open PDFs themselves. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. Most people head right to Adobe Acrobat Reader when they need to open a PDF. PDF files always look identical on any device or operating system. The reason PDF is so widely popular is that it can preserve original document formatting.
