An action potential occurs when the summated EPSPs, minus the summated IPSPs, in an area of membrane reach the cell's threshold potential. Spatial summation occurs when postsynaptic potentials from adjacent synapses on the cell occur simultaneously and add together. Temporal summation occurs when graded potentials within the postsynaptic cell occur so rapidly that they build on each other before the previous ones fade. The typical neuron has a threshold potential ranging from –40 mV to –55 mV. The resting membrane potential is usually around –70 mV. As with EPSPs, the amplitude of the IPSP is directly proportional to the number of synaptic vesicles that were released. Hyperpolarization of membranes is caused by influx of Cl − or efflux of K +. Graded potentials that make the membrane potential more negative, and make the postsynaptic cell less likely to have an action potential, are called inhibitory post synaptic potentials (IPSPs). This shows the temporary and reversible nature of graded potentials. If the EPSP is not large enough to trigger an action potential, the membrane subsequently repolarizes to its resting membrane potential. The amplitude of the EPSP is directly proportional to the number of synaptic vesicles that were released. The transmitter diffuses across the synaptic cleft and activates ligand-gated ion channels that mediate the EPSP. When the presynaptic neuron has an action potential, Ca 2+ enters the axon terminal via voltage-dependent calcium channels and causes exocytosis of synaptic vesicles, causing neurotransmitter to be released. Depolarizing local potentials sum together, and if the voltage reaches the threshold potential, an action potential occurs in that cell.ĮPSPs are caused by the influx of Na + or Ca 2+ from the extracellular space into the neuron or muscle cell. Graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential, are called excitatory postsynaptic potentials (EPSPs). The magnitude of a graded potential is determined by the strength of the stimulus. They occur at the postsynaptic dendrite in response to presynaptic neuron firing and release of neurotransmitter, or may occur in skeletal, smooth, or cardiac muscle in response to nerve input. These impulses are incremental and may be excitatory or inhibitory. They do not typically involve voltage-gated sodium and potassium channels. Spine The small protrusions found on dendrites that are, for many synapses, the postsynaptic contact site. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential. They arise from the summation of the individual actions of ligand-gated ion channel proteins, and decrease over time and space. Dendrite The receiving part of the neuron. They include diverse potentials such as receptor potentials, electrotonic potentials, subthreshold membrane potential oscillations, slow-wave potential, pacemaker potentials, and synaptic potentials, which scale with the magnitude of the stimulus. Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-none. He cannot simply kill his opponents when he has the upper hand he has to put them in a deathtrap to see if he can devise a life and death intellectual challenge that the hero cannot solve and escape. The Riddler's criminal modus operandi is so deeply ingrained into his personality that he is virtually powerless to stop himself from acting it out. Issue #2 of Justice by Alex Ross suggests that his father physically abused him, which left him with a compulsion to tell the truth (materializing through the telling of riddles), as well as a desire to prove his superiority by outwitting everyone around him. Due to his frequent appearances in other media, Riddler is often regarded to be one of the core members of Batman's rogues gallery and one of his most popular enemies.Įdward Nigma discovered puzzles when he was a young boy, and he gradually incorporated them into his criminal career. Riddler has also served as the main villain of several stories, most notably being the mastermind of the popular Hush storyline. The character would frequently appear from the 1960s onwards, becoming a recurring enemy to the Dark Knight and his allies. Originally intended as a one time villain in his first appearance, Riddler became popular after his adaptation in the 1960s Batman series and performance by Frank Gorshin. He has also fought other DC superheroes, such as Green Arrow and the Flash, and featured in several "super-villain" teams, including the Legion of Doom and Injustice League. Whilst not as physically capable as other enemies in the rogues gallery, Riddler is often considered one of Batman's most intelligent foes and has even manipulated others into various schemes. Cocreated by Bill Finger and Dick Sprang for Detective Comics #140 (October 1948), Edward "E." Nigma (sometimes Nygma and Nashton), he themes his crimes around these, even leaving clues for Batman and the police to solve hinting to his plans. The Riddler is a criminal themed around riddles, puzzles and games, and frequent enemy of Batman. " Life's full of questions, isn't it, Batman? Though, naturally, I prefer to think of them as riddles." ―The Riddler The ABSORPTION stage (the remaining 20, approximately) in the AGM/flooded 24 volt charger has the charger holding at the absorption voltage (between 28.8 VDC and 29.4 VDC, depending on charger set points) and. He charges this battery with a 950 watt of solar power system and a robust DC-DC alternator charging system. The negative diode is wrong way around so will do nothing, if the other way around the alternator will short via top diode. The target voltage for a 24 volt charger for AGM or some flooded batteries is 2.4 to 2.45 volts per cell, which is 28.8 to 29.4 volts. Steve’s DIY camper, called Maximus, features a massive electrical system centered around a 24 volt, 1,100 amp hour lithium battery bank and a buck converter that converts the 24 volts to 12 volts for some of his loads.

Contemplating,reg-micro connected across the 24v to switch a NPN fast for the Alt / solar input - with Alt / solar feed connected pos and neg to free battery terminals - but that was a disaster. This low voltage (at high current) is amplified to a 4 stage charging profile at the domestic bank. I tried a buck booster to 29v but found one battery would start taking most the charge. If the voltage stays about a volt higher than resting voltage (e.g., about 13. As people mentioned, you'll need about 28 volts at the output to charge 24V system (a battery is made of cells, lead-acid cell is described here: ).Īnother possibility (most feasible) is to buy a couple-hundred watt invertor and a 24V standalone charger (designed to work with 100-240VAC depending on your location). Then increase the engine RPM to about 3500 as you watch the reading on the multimeter. If you can find such a transformer, you will only need the rectifier/regulator box from a 24V alternator.ĭC-DC converter is a good option, but again, it has to be designed as a lead-acid battery charger, not just a power source. If this is the case, you could use a step-up transformer with 1:2 ratio, but it has to be designed for this kind of application as changing RPM changes the alternator output frequency and consequently would change the output voltage of a transformer. Most (car) alternators produce AC that goes through a rectifier and a regulator. The 33/34 SI series alternator is a brushless, heavy-duty integral charging system with built-in diode rectifier and voltage regulator, producing DC current. Well, the best option is, of course, to just buy a 24-volt alternator. For example, here’s a demo of the real endpoint: w KQkq - 2 3.png. I wrapped this in a bit of Node.js/Express code so that I could access the image as if it were static. I found chess-image-generator, a JavaScript library that creates a png from a FEN. Once again, open source to the rescue (almost). I needed two things to happen on the server.įirst, I needed to dynamically generate a board image from a FEN. This requirement introduced some server-side requirements. Dynamically creating the Open Graph image Without it, the game is a series of ugly URLs. With this capability, an image of the board will automatically display when a player sends the link. But after playing it with some friends and family, I decided that I really wanted to accomplish the other stretch goal-dynamically create a png/jpg of the chessboard that I can use as an Open Graph and Twitter card image. For example, I could add a feature that lets the user request the entire game transcript).Īt this point, there were no server requirements other than simple HTML static hosting. gid-a unique game ID (I used nanoid)-I’ll use this to connect moves to a single game in the future.from and to-indicating what move occurred (I use this to highlight the squares).Moving the pawn from D2 to D4 in a new game- īlack countering with a similar move of pawn from D7 to D5. Here's what a couple of game moves look like: A short time later, I had it working! Stretch goal #1 completed. I originally thought that making this service aware of chess rules would be difficult, but then I saw the example in the chessboard.js docs showing how to integrate it with another library called chess.js-“ a JavaScript chess library that is used for chess move generation/validation, piece placement/movement, and check/checkmate/stalemate detection-basically everything but the AI”. In only two hours, I had the basic functionality implemented. I quickly discovered that this library can display chess boards from a FEN, allow pieces to be moved, and update the FEN. One in particular that caught my eye was chessboard.js-described as “ a JavaScript chessboard component with a flexible ‘just a board’ API”. Displaying the chessboard and allowing drag-and-drop moves I knew I could use this in the URL, so my first requirement was complete and I was able to represent the board state in the URL eliminating the need for a backend data store. The last part of the string is specific to certain rules in chess ( read more about FEN). Uppercase letters represent white pieces and lowercase letters represent black. Rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1Įach letter is a piece: pawn = "P", knight = "N", bishop = "B", rook = "R", queen = "Q" and king = "K". For example, the starting position for any chess game can be represented by the following string: There is a standard notation for describing a particular board position of a chess game called Forsyth–Edwards Notation (FEN) that was exactly what I needed. Putting it all together Representing the board position Dynamically create a png/jpg of the chessboard that I can use as an Open Graph and Twitter card image so that when a player sends the link, the image of the board will automatically display.Enforce chess rules (allow only legal moves).Display a chessboard and let the player make their next move.Represent the board position-ideally completely in the URL to keep it stateless from a server-side perspective.Excited about this idea, I put together a shopping list: I wanted this to be 100% serverless, meaning that it will scale to zero and have zero maintenance requirements. Instead of tweeting moves back and forth, players tweet links back and forth, and those links go to a site that renders the current chessboard, allows a new move, and creates a new link to paste back to the opponent. I didn't have a lot of time, so I was optimizing for simplicity. Instead of designing yet another chess site (I built one with a friend in 2009 that is long since gone), I decided to create a chess board logger and visualizer to make it practical to play via Twitter or any other messaging/social platform. Later in the day, I had the idea to create a simple service that enables my use case. If I received multiple responses, I’d need multiple boards. I paused before hitting the tweet button because I realized that I’d need to set up a board (physical or virtual) to keep track of the game. I was eager to play a game, so I started to tweet, “D2-D4” knowing that some of Twitter followers would recognize this as an opening move and likely respond with their move, giving me the fix I needed. While watching The Queen’s Gambit, I was reminded about how much I used to enjoy playing chess. Technologies like blockchain and cryptography are based on hashing algorithms.A tree is used by the decision tree algorithm in machine learning. A queue is used for job scheduling - the arrangement of data packets for communication.Music players and image sliders use linked lists to switch between items.Arrays are widely used in image processing and speech processing.For example, the contact details of an individual can be stored in arrays. Some practical applications of data structures are: What are the applications of data structures? Non-linear data structures are those in which the traversal of nodes is done non-linearly.Īrrays, linked lists, stacks, and queues are examples of linear data structures, while graphs and trees are examples of non-linear data structures. If the elements of a data structure form a sequence or a linear list then it is called a linear data structure. How does a linear data structure differ from a non-linear data structure? Data structures are used in Artificial Intelligence, compiler design, database management, graphics, numerical analysis, operating systems, and statistical analysis. Similarly, B-trees are suitable for databases. There are many kinds of data structures and each of them has distinct applications.įor instance, compiler implementations use hash tables for looking up identifiers.

Both practices opened in the past few months and are accepting patients. Also serving the Southlake community utilizing the Direct Primary Care model is Covington Family Health, located at 1330 N. For those with traditional medical insurance plans, we do make referrals like they would get with regular medicine.”Ĭrescent Direct Primary Care is located at 1202 S. Often DPC physicians will build relationships with other practices/service providers in the community and identify a cash rate for services for patients referred to them from the DPC practice. How do referrals to specialists and other outside services work? “ Without traditional medical insurance, specialists or other outside services are paid for out of pocket. Instead, I can take the time to build a relationship and give them the attention their current medical situation requires, whether that means weekly visits or constant communication.” Activity-Based Costing (ABC) on the provider. Why did you decide to practice under the DPC model? “ Through the DPC model, I am able to devote the appropriate amount of time to my patients and avoid feeling rushed or pressured to prescribe them medications for a ‘quick fix’. We conducted a cost-benefit analysis and computed costs against the economic benefits of a PHC scale-up. Elvira Jasarevic, owner of Crescent Direct Primary Care in Southlake, recently shared her thoughts about the Direct Primary Care model in an interview: A membership to a DPC practice can also serve to supplement traditional medical insurance, providing patients with more comprehensive care overall with the added security of medical insurance.ĭr. Rather than paying to help supplement insurance premiums for their employees, business owners can cover all or a portion of their employees’ membership at a DPC practice.

Search by condition, specialty or name to find the best provider for you. DPC physicians charge a monthly membership fee directly to their patients in exchange for a place in their care and offer a variety of services to their patients through fee systems, without any third-party involvement from insurance. The days of finding a primary care doctor strictly through your insurance network may be on their way out! Instead, some physicians and patients in Southlake and beyond are turning to the Direct Primary Care model of health care.ĭirect Primary Care (DPC) differs from traditional medical insurance-driven practices in that it does not involve medical insurance at all.

The other alternative to surgery or a root canal would be the extraction of the tooth. If your dentist or endodontist recommend endodontic surgery, their intention is to save your tooth. Typically, endodontic surgery is only pursued if non-surgical options are not feasible. Lastly, endodontists may perform surgery (endodontic microsurgery) if you have calcium deposits inside the canals, have a tooth with complex anatomy that traditional root canals cannot treat, or need treatment on a damaged root. Other causes of reinfection of the root canal include new cracks or cavities that may have allowed bacteria to re-enter your tooth. You may need retreatment if you have complex anatomy inside your canals that the former treatment was unable to address. Lastly, they will reseal and fill the tooth. Then the endodontist will clean out the infection that remains in the tooth. This type of treatment involves removing the previously placed root canal filling material. Root Canal RetreatmentĪnother type of root canal therapy is retreatment. In other words, we do not have to drill away as much tooth! This leaves your teeth stronger and healthier over time. Similar to the Gentlewave system, the technology of the Waterlase allows our endodontists to perform root canals in a minimally invasive manner. By removing more debris from inside the tooth compared to traditional root canal methods, the Waterlase system can help patients avoid the need for retreatment. The BIOLASE Waterlase system uses light (lasers are light at a specific wavelength), water, and air to clean out bacteria from the root canals. It often only requires a single appointment to complete the root canal process compared to two for traditional treatments and has a better chance of long-term success. Plus, many patients report less pain with this type of procedure than other root canal treatment forms. By using fluids and sound waves, the GentleWave more effectively cleans out the deepest, hardest to reach sections of the tooth’s roots. This method is minimally invasive compared to the conventional form of treatment. The GentleWave root canal procedure uses files differently compared to a traditional root canal procedure. Without proper training and working to ensure they reach all portions of the tooth’s interior, an endodontist or dentist may leave infected material behind that might require a revision of treatment (root canal retreatment) in the future. This traditional method requires expertise in the use of files. Many times, a permanent restoration needs to be placed by your general dentist after the procedure. Finally, the endodontist will seal and fill the tooth. To ensure they’ve removed all debris, the endodontist will flush out the tooth’s canals with cleaning solutions. These files scrape the sides of the tooth’s interior to brush off and draw out the infected pulp. This type of cleaning involves using a series of tiny files introduced into the hole in the tooth. This entry point allows the doctor to access the inside of the tooth in order to clean it out. The traditional method of root canal treatment starts with the endodontist making a small pilot hole into the tooth. Traditional Non-Surgical Root Canal Treatment Lastly, they seal the root canals with a filling material before you get your crown or other restoration from your dentist. Next, they will open the tooth to clean out the interior using the tools of their choice. Generally, the procedure starts with the endodontist preparing the area and numbing it with a local anesthetic. The exact tools the doctor uses will depend on your tooth health and the anatomy of your root canals. Some use physical equipment, while other treatments include using lasers, water, and/or sound. The variations in types of this therapy depend on the tools the endodontist uses to clean out the root canals of the tooth. Root canal treatments all aim to remove infected or inflamed material from inside the tooth. The Goal of Different Types of Root Canal Treatments In this blog post, we describe the different types of root canals that we offer at Apex Endodontics to give you more information on the care you can receive. Endodontists have different ways to approach this problem, including non-surgical and surgical options. Root canal therapy saves natural teeth by treating infected or inflamed pulp inside teeth. And if you've ever been around a red tabby, you know how feisty they can be. On top of this, their cuddly personality has made them popular with kids and their parents alike. Other tabby owners think their cat shows sure signs of being a genius and therefore higher intelligence is another distinctive quality that cat enthusiasts associate with a tabby cat. Very often the tabby cat is considered the most outgoing cat of all, playing and exploring like no other. When it comes to the tabby cat's personality, many owners seem to think there is something special about a tabby. As soon as the silk arrived in Britain, the similarity in pattern to the coat of the so-called 'tiger cat was noticed and this particular cat soon started being called 'tabi cat' which eventually became 'tabby cat'. Now that we’ve answered ‘what are tabbys?’, where does the word ‘tabby’ even come from? It is believed the name tabby comes from a type of striped silk called Atabi, which was made in Attabiah in the Middle East. The patterns work as a camouflage when they're hiding in tall grass waiting for their unsuspecting prey. On the wilder side of the feline spectrum, the same genes give tigers and leopards their tabby pattern which helps them be such successful hunters. If you've ever looked closely at any cat in the sun, you probably noticed the subtle tabby markings starting to show up. This means that all cats are secretly tabbies - it's just more noticeable on those with patterned fur. The tabby pattern itself is the work of three types of genes that can be found in all domestic cats. To mark their special place in the feline world, all tabby cats from then on were rewarded with an 'M' on their forehead.īut the true explanation for the letter 'M' mark tells us that it all comes down to genetics. Whereas in one Islamic legend, a tabby cat named Muezza saved his master Mohammed from a poisonous snake. In gratitude, his mother Mary stroked the cat's head and left an 'M' mark on its forehead. In Christian folklore, a tabby cat dutifully showed up to comfort baby Jesus. One story has it that the 'M' is related to the word 'mau' which in Ancient Egypt meant 'cat'. It's not the coat but the hairs themselves that are striped. Although their coat stripes are very thin and barely visible on legs, face or tail, these are tabby cats through and through. Ticked tabby cats exhibit hardly any stripes or spots. This tabby shows off their distinct round spots against a background of lighter fur and might even display a faint necklace line. The next two tabby cat types have decided to do without the stripes (or the food comparisons). Similar to the mackerel type, this pattern hasn't escaped food comparisons either as many people liken it to a marble cake. They have wider stripes that tend to curve to form circular patterns and three large stripes running from the shoulders to the base of the tail. This patternis the most common of all the tabby cats. It is believed that this pattern was the original one for tabby cats. With long narrow parallel stripes running up and down the sides, they are said to resemble a fish skeleton, which is where the pattern's name comes from. There are a few groups of tabby cats - the secret is the coat pattern! Mackerel tabby cat What does a tabby cat look like?Ī tabby’s look depends on their group. They sport different colours and sizes, exist across many breeds and wear different coat patterns. In fact, tabby cats will not let themselves be easily crammed into definitions. Many people think that tabby cats are a particular breed but what makes a cat a tabby? Tabby actually refers to the coat pattern, which can be present on lots of different breeds. In fact, once you get to know them, there is nothing dull about these kitties. But as familiar as they are to us, there are plenty of tabby cat facts far from the ordinary. Tabby cats are adored all over the world, but do you know where their name comes from or what are the marks of a true tabby cat? Find out all this and more here.įrom stripes to whorls and spots, the tabby cats strut their patterned fur all over the globe. You've heard of them and no doubt you've seen them time and again. |
