Please discuss this issue on the talk page and edit it to conform with Wikipedia's Manual of Style by replacing the section with a link and a summary of the repeated material or by spinning off the repeated text into an article in its own right. This section duplicates the scope of other sections, specifically #Descents. This conforms with the description of Challenger Deep as consisting of an elongated seabed section with distinct sub-basins or sediment-filled pools. ĭetailed sonar mapping of the western, center and eastern basins in June 2020 by the DSSV Pressure Drop combined with crewed descents revealed that they undulate with slopes and piles of rocks above a bed of pelagic ooze. The closest land to the Challenger Deep is Fais Island (one of the outer islands of Yap), 287 km (178 mi) southwest, and Guam, 304 km (189 mi) to the northeast. Both the western and eastern basins have recorded depths (by sonar bathymetry) in excess of 10,920 m (35,827 ft), while the center basin is slightly shallower. The three basins feature extends about 48 km (30 mi) west to east if measured at the 10,650 m (34,941 ft) isobath. The Challenger Deep consists of three basins, each 6 to 10 km (3.7 to 6.2 mi) long, 2 km (1.2 mi) wide, and over 10,850 m (35,597 ft) in depth, oriented in echelon from west to east, separated by mounds between the basins 200 to 300 m (656 to 984 ft) higher. The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.

During the third Ring of Fire Expedition in the summer of 2022, the DSV Limiting Factor made an additional nine descents to the Challenger Deep. Between 1 March and 13 April 2021, the DSV Limiting Factor's second Ring of Fire Expedition added five completed dives. ![]() The deep-sea submersible Fendouzhe (奋斗者, Striver) completed a crewed dive to the bottom of the Challenger Deep on 10 November 2020 with three scientists onboard whilst livestreaming the descent. ![]() Between 6 June and 26 June 2020, the DSV Limiting Factor added six completed dives during the first Ring of Fire Expedition. Between 28 April and, the DSV Limiting Factor completed four crewed dives to the bottom of Challenger Deep. In March 2012, a solo descent was made by film director James Cameron in the deep-submergence vehicle Deepsea Challenger. The first descent by any vehicle was by Jacques Piccard and Don Walsh in the bathyscaphe Trieste in January 1960 unpiloted visits followed in 1996, 19. The high water pressure at this depth makes designing and operating exploratory craft difficult. The depression is named after the British Royal Navy survey ship HMS Challenger, whose expedition of 1872–1876 made the first recordings of its depth. This location is in the ocean territory of the Federated States of Micronesia. ![]() The Challenger Deep is located in the western Pacific Ocean, at the southern end of the Mariana Trench, near the Mariana Islands. The Challenger Deep is the deepest known point of the seabed of Earth, with a depth of 10,902–10,929 m (35,768–35,856 ft) by direct measurement from deep-diving submersibles, remotely operated underwater vehicles and benthic landers, and (sometimes) slightly more by sonar bathymetry.

![]() Crossover methods for bit arrays are popular and an illustrative example of genetic recombination.Ī point on both parents' chromosomes is picked randomly, and designated a 'crossover point'. Traditional genetic algorithms store genetic information in a chromosome represented by a bit array. More operators and more details can be found in the literature. The list of operators presented below is by no means complete and serves mainly as an exemplary illustration of this dyadic genetic operator type. Typical data structures that can be recombined with crossover are bit arrays, vectors of real numbers, or trees. Newly generated solutions may be mutated before being added to the population.ĭifferent algorithms in evolutionary computation may use different data structures to store genetic information, and each genetic representation can be recombined with different crossover operators. Solutions can also be generated by cloning an existing solution, which is analogous to asexual reproduction. It is one way to stochastically generate new solutions from an existing population, and is analogous to the crossover that happens during sexual reproduction in biology. Hope this info is useful, and if you want to give it a try, I recommend using a proxy/vpn and start recording those ccat test and then work on the questions and see if you can memorize them and guess correctly their answers, before you give it a live try with your account that you are going to be using.In genetic algorithms and evolutionary computation, crossover, also called recombination, is a genetic operator used to combine the genetic information of two parents to generate new offspring. The anally retentive vp of support that currently handles all this crap is one named dani vasileva or soemthing like that. First you have to get thru that ccat, which is totally stupid, as a ccat should only be taken into consideration as a sketch of how a person is going to be and not as a work requisite. We stayed doing nothing(but getting paid)for about 3 months, then I resigned because I could not stand the idleness. ![]() They took us, a team of around 40, out of the production line and brought there techs from Central Support.ĭue to their modus operandi, the L1s brought were shocked because they didnt do any kind of troubleshooting at all, they were accustomed to finding solutions in a runbook and mail back the resolution. They came in after a looong wait and wanted to migrate a product and have a rookie tech digest the whole thing in 4 weeks, when the ramp up of a beginner tech was 4 months. THe product that I worked for was pure software, it is so complicated that in practice, each customer had a personalized version due to customizations and integrations. When I was in, I was top scoring performer, but then I resigned because I was part of one of the newer acquisitions, and they were way eager to put the product I was working for in their support model, The Factory. Seems like they catched up people cheating on the ccat and took measures, but this has only alienated them to the talent tool. They will have you connect your cell phone to zoom session, they make you film the area around you where you are taking the exam and then they have you put your cellphone filming the keyboard/desk. If you manage to score the ccat and move forward, eventually, you will have to do another ccat, but this one is proctored. With the new changes, if you dont score 35, a solid 35 on the initial ccat test, you wont move forward in the hiring process and you get banned for 6 months for a retry. When I got it, there where some aptitude test, basic knowledge test and then the human interview process. Now I'll elaborate more about the recent changes to the hiring process. They have runbooks to solve all problems and the L1s work by those and if they cant find a solution in the runbook, they elevate it to L2. They have a Hive Mind mentality towards the support process. Most of the products that they already have, are pretty much square in their functionality, a piece of relative simple functionality, some software and some products are really complicated. Central Support/The Factory(as they call it internally)handles the support for all their products, while Acquisitions analyzes and digest new acquisitions and assimilates them into the collective. They work by purchasing other products/companies and add them to their portfolio of products.Ĭrossover does the hring/HR/payroll part. Crossover itself is just one company out of of a portfolio of business that ESW Capital has(this is the parent company). The pay is way above average for anyone now based in the US. The process was challenging but not extreme(when I got in). I worked for Crossover as an L1 Tech Support. ![]() You can add as many names to this list as necessary.

His full name is sometimes given as "Marcus Vitruvius Pollio", but both the first and last names are uncertain. Most inferences about him are extracted from his only surviving work De Architectura. Though the original illustrations have been lost, the first illustrated edition was published in Venice in 1511 by Fra Giovanni Giocondo, with woodcut illustrations based on descriptions in the text. Translations followed in Italian, French, English, German, Spanish, and several other languages. The first known Latin printed edition was by Fra Giovanni Sulpitius in Rome in 1486. Leon Battista Alberti published it in his seminal treatise on architecture, De re aedificatoria ( c. Vitruvius' De architectura was widely copied in the Middle Ages and survives in many dozens of manuscripts though in 1414 it was "rediscovered" by the Florentine humanist Poggio Bracciolini in the library of Saint Gall Abbey. It is possible that Vitruvius served with Julius Caesar's chief engineer Lucius Cornelius Balbus. As an army engineer he specialized in the construction of ballista and scorpio artillery war machines for sieges. ![]() ![]() He probably served as a senior officer of artillery in charge of doctores ballistarum (artillery experts) and libratores who actually operated the machines. Little is known about Vitruvius' life, but by his own description he served as an artilleryman, the third class of arms in the Roman military offices. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing of the Vitruvian Man by Leonardo da Vinci. These principles were later widely adopted in Roman architecture. He originated the idea that all buildings should have three attributes: firmitas, utilitas, and venustas ("strength", "utility", and "beauty"). 15 BC) was a Roman architect and engineer during the 1st century BC, known for his multi-volume work titled De architectura. ![]() Kúkpi7 Rosanne Casimir, elected chief of Tk'emlúps te Secwépemc, says she stopped being able to use social media without "heavy filters" due to the hate and racism that inundated her and others in the community in the wake of the findings, according to Murray's Friday report.Ĭasimir did not return a request for comment before publication.

They work the chest, the back, the shoulders and to some degree – even the arms. Just like squats working the lower body, pullovers work every last bit of the upper body. However, I’d argue that the dumbbell pullover may just pip it to the post. The dip is often touted as the upper body squat and with good reason – it basically is. It can be used at the begining or end of a workout, it can be a chest or a back exercise, it can be done low reps or high reps – it’s such a multi-faceted move.Īnyway, I’ve listed a few of these unique benefits below to whet your appetite. The dumbbell pullover comes with so many benefits. Then, try to pull with your elbows like you would for rows – this allows for a clear focus on the back and will help burn the lats out nicely. Hold the bottom position for 2-3 seconds and focus on the contraction in your lats. God I hate saying that so much.Īll you have to do to really feel this in the lats is to get that stretch. As this is where the lats are most dominant, it could mean that I am getting a stronger mind muscle connection there. This could be because I tend to hold the stretch at the bottom of the movement for about 2 seconds. ![]() I’ll be honest with you, when I perform pullovers, I actually feel it more in my lats. This is a little bit tougher but it’s not rocket science – you can still do it easily enough. This will help to really empty the tank and isolate your pecs nicely. This is why so many old-school bodybuilders such as Arnold Schwarzenegger and Reg Park credit the dumbbell pullover for their amazing chest development.Īll you have to do is really squeeze the pecs throughout the full movement as this is one of those exercises that actually requires that mind muscle connection. Having the dumbbell behind/above the body and bringing it to the front of the body is naturally a chest-dominant move. Starting with the chest – this is a bit easier as the pullover does lend itself more towards chest activation. With that in mind, let’s break down how best to perform a dumbbell pullover for each. Is it a chest or a lat movement? Well, it’s both. Well it’s less of a community and more just a few fellas arguing online about muscle activation. There is a debate that rages amongst the dumbbell pullover community. It does still offer huge benefits for building a back like a barn door though as we will discuss a bit further down. The pullover allows for the chest to placed in an optimal position and the stretch that you get from it affects the muscles in the same way that flyes do but with the added bonus of being able to load heavier weight for more reps.Īt the bottom of the move, the stretch places a huge emphasis on the lats too, although once you lift the dumbbell past your head, this effect is lessened to some degree. Knowing about the mechanics behind the lift is key to understanding how to target certain areas and why different ways are better for different situations. We’ve talked about the history of the lift but let’s get into the nitty gritty – the mechanics.
