This discovery led to the realization that bacterial cells are far more organized than was previously anticipated. In their seminal paper >20 years ago, Maddock and Shapiro showed that bacterial chemoreceptor clusters are specifically localized at cell poles in Escherichia coli 7. These intricate signal transduction complexes regulate flagellar rotation, thereby controlling the swimming direction of bacteria 10, 11. The assembly of individual sensory proteins into large clusters provides high sensitivity, and allows the cell to integrate various environmental signals into a unified output 8, 9. Together with specific kinases, phosphatases and receptor-modulating proteins, they form large stable sensory clusters. A classic example is the polar localization pattern of the chemotactic sensory complexes 6, 7.īacteria sense their surrounding by transmembrane or cytoplasmic chemoreceptor proteins that form dimers, which assemble into trimers. Despite its importance, we still do not have a good understanding by which mechanisms proteins are sequestered to the bacterial cell poles. In rod-shaped bacteria, the cell pole is such an area to which a large number of proteins are recruited 2, 3, 4, 5. These findings demonstrate that the intrinsic shape of transmembrane proteins can determine their cellular localization.Ĭells rely on a strict cellular organization for their growth and function, and many biochemical processes are confined to specific areas in the cell 1, 2. By constructing specific amino-acid substitutions, we demonstrate that the preference for strongly curved membranes arises from the curved shape of chemoreceptor trimer of dimers. Localization appears to be an intrinsic property of the protein complex and does not rely on chemoreceptor clustering, as was previously shown for Escherichia coli. This preference was confirmed by accumulation at non-septal curved membranes. Here we show that the classical chemoreceptor TlpA of Bacillus subtilis does not localize according to the consensus stochastic nucleation mechanism but accumulates at strongly curved membrane areas generated during cell division. A typical example is the assembly of bacterial chemoreceptors at cell poles. In most cases, we have a poor understanding of the underlying mechanisms. The intricate structure of prokaryotic and eukaryotic cells depends on the ability to target proteins to specific cellular locations.

Then the flume will take you to the highest part of the ride at 30-foot (9.1 m). Once at the second highest part of the ride, you dip down and curve through turns, back and forth along KIDZOPOLIS and over the ride below it. After the small first drop, then flume makes an almost complete circle to the right, and then takes you up to the second tallest section of the ride. Once riders get on Bugs' White Water Rapids, the flume takes a right coming out of the station where the ride begins traveling towards the first lift hill. The ride was manufactured by Hopkins Rides and constructed by Martin & Vleminckx. It then opens back up until the end of the season. During Holiday in the Park, the ride is closed, as the queue building is transformed into "Santa's Castle" until Christmas. The ride is the longest operating water ride in the park each season, operating from opening day through Fright Fest and Holiday in the Park. It will effectively double the capacity of the ride by allowing passengers to unload and load one train while the other one is on the tracks.Bugs Bunny and Yosemite Sam theming on the rideīugs' White Water Rapids has two lift hills and two drops. In the intervening years, Six Flags decided to add a second train and install a turntable in the loading station. “It will be a great way for guests to beat the heat this summer.”Īquaman was supposed to open in 2020, but was delayed by the pandemic. “The most technically advanced thing about this ride is how much water will be pumped into the splashdown pool,” says Malone. It will create a huge plume of water, and it’s likely that passengers will get positively soaked. While it hangs momentarily on the tower, the water level will quickly rise in the pool under the tracks so that the train will make a big splash when it drops into the water. For the final launch, the train will hit its top speed of 63 mph and head backwards up the tower with enough momentum to make it to the top. Each time it stalls on the towers, passengers will experience airtime. The train will drop down and rev up a second time heading forwards up the opposite tower. It will first launch backwards, rising partway up one of the towers. The attraction is a curious mix of buccaneers, aliens, and Lone Star State ambiance that is distinctly Six Flags Over Texas. Guests then enter the speelunkers’ cave for the second half of the ride experience. There are also encounters with mermaids and sea monsters. The first part of the story introduces pirates that are trying to find and pillage the speelunkers’ treasure. The facade of the attraction includes nautical touches that gives it a coastal, Galveston-like vibe, befitting its location in the Texas section of the park. “The projections and technology make it seem like the scenes are larger and more immersive,” Malone adds. The animatronics are considerably more sophisticated, and the physical sets include projected media that depict roiling seas and other effects. “We wanted to make sure would pay homage to the original, but also brought it up to the 21st century,” says Brad Malone, spokesperson for the park. Pirates of Speelunker Cave, as it is now known, brings back the funky aliens, but gives them some contemporary love. The attraction remained until 1991 when it was replaced by Gold River Adventure, which gave Yosemite Sam, Bugs Bunny, and other Looney Tunes characters the opportunity to bring their silliness to the park.Ī couple of weeks ago, the attraction returned to its roots with yet another makeover. Built in house, it featured “speelunkers,” goofy-looking alien creatures that dwelled in the cave and mined its gems. Like “ it’s a small world ,” The Cave used boat vehicles. (And don’t start yelling at me about those lower-case title letters they are intentional on the Mouse’s part.) The bright, cheery “it’s a small world” attractions at the Disney parks are dark rides, for example. They are not necessarily dark in tone or light level. A dark ride, by the way, is an industry term for any attraction that moves passengers through an indoor show building in a vehicle. With the 1964 opening of The Cave, it can also lay claim to one of the first modern-day dark rides. Inspired by Disneyland, it is hailed as the first regional theme park and is the home of the first log flume ride as well as the first mine train coaster (both of which are still operating). Opened in 1961, the original Six Flags park still has some echoes of its early days. There’s a certain authentic je ne sais quois at Six Flags Over Texas. The new Pirates of Speelunker Cave dark ride (Six Flags) Haskelly, and VScode together also offers IDE-like features such as Intelligent Code Completion, and allows for an easier transition when you begin to learn languages such as Java, where most choose to rely on an IDE. Haskelly offers is text-hovering, which can show additional information such as function type definitions. This allows for easy simplification of duplicated code. For instance, highlighting a section of your code would also highlight all the other instances where this exact line of code has come up, and pressing “Ctrl-F2” would allow for refactoring all the instances. VScode has many features that your average text-editor would not have. There are many other uses of this command palette, and you can type “?” in it to find more, or type in relevant key words to find what you’re looking for. Typing in “git clone” will allow you to paste in a git repository URL, and download it to your desired location. To begin simply press (Ctrl-Shift-P) to bring up the command palette, where you can search for the many features that VScode offers. To test VScode, I decided to redo one of my past papers with it. , a Haskell extension has all the listed features, and many more as highlighted below. Basic text editors lack functions such as text suggestion, Git support, and many other features. Many of us were taught to code in a text editor like Atom for Haskell, and use command line to compile and run our program. Of course, Java has its benefits, but as a beginner, it is much easier to pick up Haskell than Java. Haskell (Left) is clearly easier to learn for a beginner, and even the more complex list comprehension version (Line 4) is easier than the 23-line long Java (Right) method. Haskell, a functional programming language, is a great introduction to programming due to its similarity to maths in basic functions, as well as its simplicity to run and compile.įor example, the following code will read a list of integers from command line, then double each element of the list, and print it out.

This is a complex topic definitely worthy of a book in itself. He already has a publisher which is a coded all this up so is best placed to write a book on the subject. I completely agree with the list of books you have written above but who to write them all? Here's who I think:īeginners (everyday gfx and perhaps could update his book to a second edition to take account of 3D graphics and new Sprites classes like Path2D and Pixel. Thanks for all your comments! I can see most people prefer to use online documentation for the API so perhaps a printed text is not really essential. It brings back fond memories of flicking through my Amiga Hardware Reference Manuals :bz Maybe just a horizontal line that separates the different functions? The main heading (Chapter 81) is cool but I'm not fond of 81.1, 81.2, etc. I would get rid of the "available since" lines because I feel they are irrelevant when looking up a function/params/syntax. Maybe if it were an E-Book with free updates it might work (for me at least)Īs for the format and such, it's pretty good. If they shared the same format that would be grand. Personally I feel as more new things are added I would be having to go back to the online documentation still, which kind of defeats the purpose of having a book that contains everything. My only hesitation on purchasing something like this is the speed at which Gideros is moving forwards. Just looking at other SDK's there are many other ways the information could be better presented. I always thought the documentation could be way better. Many thanks for your advice on those are very nice. What do you think of the formatting presented in the samples? How much would you want to pay for such a book? So I would like your comments! In particular: I attach some samples from the book as it exists so far. Currently the book is 460 pages long nominally on A4 paper (though the paper size could be shrunk a fair bit without compromising readability). I prepared a version of this book in 2014 as a reward for a Kickstarter campaign but this version will need to be updated as many more features have been added to Gideros. The information is the same as you can find here on this site (in the API reference) but obviously set in a nice book form and with everything gathered in one place. The manual will contain a description of all of Gideros's 500+ API functions including all plugins and Lua standard libraries. I am thinking of publishing a new physical book on Gideros, namely a Gideros Reference Manual and I would like to gauge interest in this. Reconstructing the Cosmos at the front of the Antikythera Mechanism begins with analysing some remarkable inscriptions. What has struck us forcefully in making the present model is just how few these options are: the constraints created by the surviving evidence are stringent and very difficult to meet. The loss of evidence might suggest many options for a model. With so much missing, we ensure the integrity of our model with a strict set of Reconstruction Principles (Supplementary Discussion S1) and we assess the strength of data that validates each element-discussed in Supplementary Discussion S1. The result is a radical new model that matches all the data and culminates in an elegant display of the ancient Greek Cosmos. Here we show how we have created gearing and a display that respects the inscriptional evidence: a ring system with nine outputs- Moon, Nodes, Mercury, Venus, Sun, Mars, Jupiter, Saturn and Date-carried by nested tubes with arms supporting the rings. We wanted to determine the cycles for all the planets in this Cosmos (not just the cycles discovered for Venus and Saturn) to incorporate these cycles into highly compact mechanisms, conforming to the physical evidence and to interleave them so their outputs correspond to the customary cosmological order (CCO), described below. Then came the discovery in the tomography of surprisingly complex periods for the planets Venus and Saturn, making the task very much harder 12. There were also unexplained components in Fragment D, revealed by the X-ray CT, and technical difficulties calculating the phase of the Moon 9. The evidence defines a framework for an epicyclic system at the front 9, but the spaces available for the gears are extremely limited. The tomography revealed a wealth of unexpected clues in the inscriptions, describing an ancient Greek Cosmos 9 at the front, but attempts to solve the gearing system failed to match all the data 1, 2, 3, 6, 9. Features on the Main Drive Wheel indicate that it calculated planetary motions with a complex epicyclic system (gears mounted on other gears), but its design remained a mystery. Our challenge was to create a new model to match all the surviving evidence. None of these models (Supplementary Discussion S6) are at all compatible with all the currently known data. Most previous reconstructions used pointers for the planetary displays, giving serious parallax problems 3, 9 and poorly reflecting the description in the inscriptions-see section on Inscriptional Evidence. S19), and independently by Carman, Thorndike, and Evans 11, simplified the gearing but were limited to basic periods for the planets. Later attempts by Freeth and Jones 9 (Supplementary Fig. Then Wright built the first workable system at the front that calculated planetary motions and periods, with a coaxial pointer display of the Cosmos, proving its mechanical feasibility 3 (Supplementary Fig. In the classic, Gears from the Greeks 2, Price suggested lost gearing that calculated planetary motions, but made no attempt at a reconstruction. In 1905–06, remarkable research notes by Rehm 1 described Mein Planetarium, with a ring display for the planets that anticipates the model we present here-but mechanically completely wrong due to his lack of data (Supplementary Fig. Many unsuccessful attempts have been made to reconcile the evidence with a display of the ancient Greek Cosmos of Sun, Moon and all five planets known in antiquity. The front remained deeply controversial due to loss of physical evidence. This led to a solution to the back of the machine 4, 7, 8, 9, with the discovery of eclipse prediction and the mechanization of the lunar anomaly 7 (Supplementary Fig. In 2005 Microfocus X-ray Computed Tomography (X-ray CT) and Polynomial Texture Mapping (PTM) of the Mechanism’s 82 fragments 7 added substantial data. The fragments are a 3D puzzle of great complexity. Fragment A contains 27 of the surviving 30 gears, with a single gear in each of Fragments B, C and D 2, 5, 7, 10. Nevertheless, they are rich in evidence at the millimetre level-with fine details of mechanical components and thousands of tiny text characters, buried inside the fragments and unread for more than 2,000 years 7. They are partial, damaged, corroded and covered in accretions (Supplementary Fig. The major surviving fragments of the Antikythera Mechanism are labelled A–G and the minor fragments 1–75 7. It was a mechanical computer of bronze gears that used ground-breaking technology to make astronomical predictions, by mechanizing astronomical cycles and theories 1, 2, 3, 4, 5, 6, 7, 8, 9. The Antikythera Mechanism is a cultural treasure that has engrossed scholars across many disciplines.
