Essential Paddling Tips from Pros

first_imgPat KellerThree-time long boat Green Race champion; whitewater’s sweetheart of the SoutheastLearn your boat by first taking it out to the lake. The best way to know your craft and how it will respond in varying currents is to be aware of what its rocker and edges will want to do. A quick drill on flatwater will help you dial this. First, get up to speed. Once you’re moving, you have four options:1. Lean to the front left edge2. Lean to the front right edge3. Lean over the back left edge4. Lean over the back right edge.Try all four of those and just see what the boat wants to do.Shane BenedictTwo-time medalist at World Freestyle; co-founder of Liquidlogic kayaksI have always thought of my top skill as being precision. I regularly use a broad repertoire of strokes to the point that they become second nature. Practice freestyling and old-school-style eddy hopping to learn how to visualize tight, precise lines and put the boat exactly where you want it with the right momentum and angle. It also doesn’t hurt to know how to scramble like a mofo when you are dealing with Plan B.Nick TroutmanBronze medalist in Freestyle World Championships 2007; three-time Canadian national freestyle championOne of the most important and most underrated skills is edge control. It’s the difference you notice between someone flying through the rapid fast and stylish compared to someone just making it down the rapid. You edge the boat to miss tapping on a little rock or catching your edge on an eddy line; it’s also about knowing exactly when to edge to take a boof stroke or land a boof. To practice, just try simple tricks like seeing how long you can edge on your side without having your paddle in the water. Get farther onto your sidewall until you eventually fall over. This skill takes time to master, though luckily you can practice anywhere.Clay WrightFirst Green Race winner; squirt boating icon; inventor of “the loop”Practice failure. Try really hard moves in safe places. You’ll learn the very real skill of dealing with where you are when you aren’t set up for the rest of the drop. Try rolls or 360s between eddies, attempt eddies that are too shallow or small and learn to grab at rocks or fall out the back and get back on track. Paddlers who can improvise quickly form better back-up plans and get to run challenging lines with less risk.Anna LevesqueBronze medalist at Freestyle World Championships 2001; founder and owner of Girls at PlayThe skill I think is crucial for styling a rapid is confidence. Confidence and skill are related. The better skill (technique) you have, the more confident you’ll feel; the more confident you feel, the better you’ll perform. Building confidence has four components:1. Learn and practice good technique.2. Gain experience. Get out and paddle.3. Feel supported by your paddling peers.4. Learn from the bad lines, but don’t focus on them.Confidence comes from recognizing our strengths while we learn from our weaknesses.last_img read more

One Wrong-Handed Amino Acid Can Cause Vertigo

first_img(Visited 717 times, 1 visits today)FacebookTwitterPinterestSave分享0 The rocks in your head that give you a sense of balance are finely tuned to spiral in a certain way.We’ve mentioned chirality before in articles on the origin of life. One of the difficulties for secular scientists is explaining how life ended up with one-handed (chiral) building blocks, like amino acids and sugars, when both are equally likely to form by the laws of physics. That remains a major unsolved problem in origin-of-life studies, because proteins cannot work unless 100% one-handed.Another case of chirality just turned up in the human body: inside the inner ear, little crystals of calcium carbonate will fail to work if one amino acid goes right-handed instead of left-handed.Tiny crystals of calcium carbonate help us keep our balance.In a press release from McGill University on “Chirality Switching in Biomineral Structures,” researchers found one reason why some people develop vertigo. We all have little rocks in vestibules (sacs) within our inner ears, called otoconia. Those crystals are not just chips off the old block; they are carefully constructed by “proteins that guide the biomineralization process.” When otoconia grow correctly, they spiral in a certain direction. The scientists found that a single wrong-handed amino acid can make them spiral the opposite way, leading to failure in the balance organ.Remarkably, they could also make the helicoids turn clockwise or counterclockwise by simply using only either the left-handed or right-handed version of the amino acids aspartic acid and glutamic acid – these being abundant in proteins that guide biomineralization processes in many organisms.“This work provides key information towards understanding how organisms can have biomineralized structures rotating in opposite directions,” says McKee, senior author of the study. “Our findings also give insight into pathologic chiral malformations that might arise in human otoconia, structures in the inner ear whose normal functioning maintains balance by gravity sensing and by detecting linear acceleration. Our work predicts how pathologic chiral malformations might arise in human otoconia and could one day be used to develop therapies for vertigo (loss of balance) based on this understanding”.Snail (DFC)The paper in Science Advances, the open-access journal of the AAAS, gives the details of how the crystals grow. They spiral one way, then at a certain point, the spirals switch and grow the other way, overlapping as they grow. Adsorption of the one-handed enzyme on the crystal explains how the crystal can start growing with a left-handed spiral, and then switch to a right-handed spiral as layers build up. The outcome is finely dependent on the enzyme’s sequence. The authors say that “chiral switching” operates not only in the inner ear otoconia, but in snail shells that on rare occasions spiral the opposite way from normal.This layer-by-layer rotational circular growth model for vaterite structures, which also provides a chiral switching mechanism, may be part of organic contributions to chiral switches observed in mineralized structures in biology, where biomineralized shells and other structures such as coccolith skeletons and pathologic human vaterite otoconia have chiral structures. Not only do the data support the postulate that simple acidic amino acids are potentially involved in producing chiral mineralized architectures both large and small, but they also additionally suggest that more complex chiral biomolecules may provide additional hierarchical instructions for extended structure in biomineralization.The paper calls science’s lack of understanding of the origin of chirality an “Achilles’ heel” of biology, but ends on a biomimetic note:In summary, this work demonstrates that two imperfect oriented attachment growth mechanisms operate in establishing chiral hierarchical vaterite helicoids induced by the adsorption of a single chiral enantiomer of an acidic amino acid onto a vaterite crystal, and whose helicoid chirality can be switched. These findings advance our understanding of why, despite a lack of d-enantiomer [right-handed] amino acids in biology—the “Achilles heel” of understanding the origin of enantiomeric pairs of biominerals from chiral amino acids—various enantiomorphs of biomineral may indeed be formed by homochiral biomolecules (more specifically l-acidic amino acids, as found in nature). The findings also describe a new organizational function involving mineral crystal-biomolecule interactions over different length scales that may prove useful in the development of novel composite/hybrid functional materials. The findings also allowed us to build a growth model for pathologic human inner ear otoconia that predicts other pathologic forms—as yet to be discovered—whose formation may one day be modified by therapies based on this understanding.A sidebar in the press release explains chirality in molecules.How about that; another fine-tuning example in biology, and a clever trick that scientists want to imitate! Your body is more wonderful than you can possibly imagine. It makes you dizzy just thinking about it. Be thankful today if you can bend over without losing your balance. Be thankful anyway, even if you do lose your balance. You can read this, can’t you?last_img read more

Jordan Says It Will Begin Censoring Websites

first_imgWhy Tech Companies Need Simpler Terms of Servic… Tags:#international#news#NYT#web The Jordanian government has ruled that electronic communication like websites will be subject to the country’s Press and Publications Law, prohibiting speech that insults religion, according to reports from the region. Jordanian blogger Gaith Saqer covered the news in English this afternoon on his blog Arab Crunch.Critics of the ruling worry that the law will be widely applied to social media, possibly even SMS and to websites that allow reader comments to be posted. Supporters appear to argue that free speech comes with responsibilities along these lines and that the legal framework actually facilitates online communication.More information is available from the large Jordanian site AmmonNews or translated in English here.Saqer contacted Google regarding this new front in the battle over censorship and democratized publishing online; he reports that a spokesperson said the company had no comment at this time.Jordan isn’t unique in having a law that prohibits publishing words critical of religion. The Egyptian government has now held blogger Abdul Kareem Nabeel Suleiman in prison for more than 3 years for contempt of religion and defaming the president of Egypt on his blog. The international watch-dog group Reporters Without Borders issued a press release yesterday saying the Egyptian government has now blocked Suleiman from meeting in jail with his lawyers for a third time.

Blockchain Supercharged with AI: The Next Revolution

first_imgRelated Posts Tags:#AI#artificial intellgence#Blockchain Blockchain – Impending Revolution in Glob… How Data Analytics Can Save Lives AI: How it’s Impacting Surveillance Data Storagecenter_img In the last decade, Blockchain and Artificial Intelligence (AI) are among the rare developments in technology that is poised to become so disruptive that they’ve become synonymous with innovation and the future. Startups have begun aiming to bring an amalgamation of these technologies onboard and have raised a whopping $437 million to date(source). But what are these technologies and why are they so disruptive?Blockchain technology was created by an anonymous figure known as Satoshi Nakamoto and is the underlying technology behind the sensational Bitcoin.The Blockchain is a distributed ledger technology (DLT) that enables the storage of data securely and transparently.  While cryptocurrencies have been taking the financial ecosystem by storm, blockchain has permeated into almost every industry sector imaginable, from Healthcare to Gaming. The technology is gaining momentum at an unprecedented pace, so much so that by 2023 the global blockchain market is expected to grow to $23 billion by 2023 (source).Artificial Intelligence was first described by John McCarthy in 1956. This Artificial Intelligence (AI), is the ability of a machine/program to learn from its experiences, much like a conscious being does. In most cases, an AI system requires a vast amount of data to “learn” from its experiences and make a decision accordingly.Even though the technology is still in its nascent stages, an excellent example of the capabilities of current AI technology is the array of virtual assistants available like from Tech giants like Google, Amazon and Apple. Similar to the blockchain, AI is making waves in scores of industry sectors by helping augment existing technologies by increasing its efficiency. The global AI market is expected to reach a whopping $190 billion by 2025 (source).At first glance, blockchain and AI seem poles apart and they are. But recent developments in Big data has created a conducive environment for the amalgamation of these technologies.The convergence of Blockchain and AI.The most compelling motivation for combining blockchain and AI originates from the need to augment big data analytics. Big data analytics involves examining excessive amounts of data, often about customers, to unravel correlations between seemingly distinct data points that could provide insight into the dataset. In retrospect, big data analytics has commonly been used by enterprises to boost customer acquisition and retention, introducing targeted advertising and even improve risk management.In simple terms, enterprises are looking to improve their profits by better understanding their customer base.This corporate agenda would have been impossible today without the rise of social media platforms and the internet. On top of having access to the social media activity of users, companies often have access to shopping behavior, geographical information and even political preference for at least two billion people. But this data is often chaotic, vast and random.This chaos is where AI kicks in. Artificially intelligent algorithms can be taught to draw meaningful insights from the hoard of data available. Where does Blockchain fit into all this?How blockchain can help artificial Intelligence.Artificial intelligence needs vast amounts of data to learn and make insightful decisions; blockchain becomes useful a novel way of storing data securely. As mentioned earlier, blockchain often boils down to being a distributed ledger technology, which means it creates a massive database of every transaction on the network. But unlike traditional data storage solutions like Amazon’s servers — which are centralized — blockchain networks are decentralized.If a network is decentralized, it means that the blockchain stores data on a vast network of computers, which regularly verify the information with each other, making the data stored on the network immutable. In case a hacker gets into one computer and manipulates the data, the abnormality is often picked up by the other computers on the network, and the data manipulation made invalid.On top of this, the data stored on blockchain is cryptographically secured meaning modifying the data is incredibly difficult.Blockchain users can also check if the data stored on the network has been tampered with, by simultaneously cross-checking cryptographic signature of the data across all nodes (computers) on the network. This ability to curtail any modifications makes Blockchain an ideal solution to store highly sensitive data. The same can’t be said for our current networks and systems, which are often the victims of cyber hacks.For example, In November last year, the Marriott hotel group revealed hackers stole the personal data of as much as 500 million of its guests. From these all too familiar scenarios of hacking thefts, we can conclude that blockchain will be a critical element in the advancement of AI systems and Big data analytics and solutions. But can AI be useful for blockchain?How Artificial Intelligence can help blockchain. AI systems could profoundly change the way we manage blockchain networks and make them more efficient. For example, while transferring Bitcoin to another peer on the same network, it often takes days to confirm the transaction. Ironically, this is inadvertently caused by blockchains decentralized nature as transactions facilitated on Bitcoin’s network is established by Bitcoin miners, who group these transactions into blocks.Therefore an unprecedented increase in Bitcoin transactions could delay the confirmation time even further as ‘block’ sizes are limited, meaning transactions which exceed the capacity of a block will get queued for confirmation by Bitcoin miners.Artificially intelligent systems could help bring down this cumbersome process by reducing the computing power needed to confirm these transactions. As the Hashing algorithms used to confirm transactions on a blockchain network often uses a “brute force” approach. An AI system could possibly be trained to improve these algorithms by providing it with the right data.Top five startups in this niche space, according to funds raised($MM)Neuromation – $72 millionEndor- $45 millionBlockchain data foundation- $38 millionSingularity.NET- $33 millionNeurochain-$25 millionThese are the top five startups, in terms of funds raised, looking to usher in a new era technology by combining Artificial Intelligence and Blockchain technology. Even though, by itself, funds raised is not a precise way to measure the success of a startup or for that matter the potential of a new market. It does provide conclusive evidence that investors are confident in the potential of combining these technologies and are willing to pledge top-dollar to some startups in this realm.Therefore even though Blockchain technology and Artificially intelligent systems already garner tremendous potential for revolutionizing many industry sectors. But an amalgamation of both could be the advent of a new era of technology, one that will bring growth to various industries on an unprecedented level.
