Antennas broadcast radio waves in different directions depending on design choices. Moving on from toy scenarios-the hairy ball theorem actually imposes tangible limitations on radio engineers. Does this violate the hairy ball theorem? No, because drilling a hole transformed the ball into a doughnut! Even doughnuts with unusually long, narrow holes flout the rules of the theorem-contradiction averted. What if we bored a tiny hole through the ball exactly along that axis to remove the stationary points? It seems then that every point would be moving. A spinning ball rotates around an invisible axis, and the points on either end of that axis don’t move. Upon further reflection, this might seem obvious. Spinning is a continuous motion, so the hairy ball theorem applies and assures a point with no speed at all. Again, we associate a tangent vector with each point based on the direction and speed at that point on the ball. There will always be a point on the surface that has zero velocity. To observe another weird ramification of the theorem, spin a basketball any which way you want. This neat online tool depicts up-to-date wind currents on Earth, and you can clearly spot the swirly cowlicks. A cowlick could occur in the eye of a cyclone or eddy, or it could happen because the wind blows directly up toward the sky. (Vector magnitudes don’t need to represent physical lengths, such as those of hairs.) This meets the premises of the theorem, which implies that the gusts must die somewhere (creating a cowlick). The wind flows in a continuous circulation around the planet, and its direction and magnitude at every location on the surface can be modeled by vectors tangent to the globe. Here’s a curious consequence of the hairy ball theorem: there will always be at least one point on Earth where the wind isn’t blowing across the surface. This doughnut shape is covered in small lines resembling hairs that are all combed in the same direction, with no tufts resulting. Doughnuts are also distinct from spheres, so a hairy doughnut-an unappetizing image, no doubt-can be combed smoothly. So sadly, math can’t excuse your bedhead. A scalp on its own can be flattened into a surface and combed in one direction like the fibers on a shag carpet. Something that is not equivalent to a sphere is your scalp. (You could mold them all from a ball of Play-Doh without violating the rubbery rules.) This means that the hairy ball theorem automatically applies to hairy cubes, hairy stuffed animals and hairy baseball bats, which are all topologically equivalent to spheres. If one shape can be smoothly deformed into another without doing these things, then those shapes are equivalent, as far as topologists are concerned. Although that rubber is capable of molding into other forms, it is incapable of tearing, fusing or passing through itself. In the field of topology, mathematicians study shapes, as they would in geometry, but they imagine these shapes are made from an ever elastic rubber. This claim extends to all sorts of furry figures. Tufts on either side demonstrate the hairy ball theorem. This sphere is covered in small lines resembling hairs that are all combed in the same direction. In full jargon: a continuous nonvanishing tangent vector field on a sphere can’t exist. If we stitch these criteria together, the theorem says that any way you try to assign vectors to each point on a sphere, something ugly is bound to happen: there will be a discontinuity (a part), a vector with zero length (a bald spot) or a vector that fails to be tangent to the sphere (Alfalfa). In other words, the arrangement of vectors on the sphere must be continuous, meaning that nearby hairs should change direction only gradually, not sharply. Also, we want a smooth comb, so we don’t allow the hair to be parted anywhere. Combing the hair flat against the sides of the coconut would form the equivalent of tangent vectors-those that touch the sphere at exactly one point along their length. A vector, often depicted as an arrow, is just something with a magnitude (or length) and a direction. In more technical language, think of the coconut as a sphere and the hairs as vectors. Of course, mathematicians don’t refer to coconuts or cowlicks in their framing of the problem. Here, “cowlick” can mean either a bald spot or a tuft of hair sticking straight up, like the one the character Alfalfa sports in The Little Rascals. Juvenile humor aside, the theorem has far-reaching consequences in meteorology, radio transmission and nuclear power. Perhaps even more surprising, this silly claim with an even sillier name, “the hairy ball theorem,” is a proud discovery from a branch of math called topology. You might be surprised to learn that you can’t comb the hairs flat on a coconut without creating a cowlick.

Says Meredith Cash, writing for Insider in September 2019, “The Cinderella Latte is less of a drink than it is a dessert. The Cinderella Latte has since had its viral moment - as much for its widely reported origin story as for the way it tastes (i.e. Its creator, Erica Howard-Cox, a former barista and die-hard Disney fan, describes her inspiration: “The combination made me think of the scene where Cinderella’s fairy godmother turns an ordinary orange pumpkin into a beautiful white pumpkin carriage.” Just in coffee form. It’s the seasonal obsession of Starbucks’ PSL plus the magic of Disney, all in a Venti cup. But there’s obviously more to it than that. Practically speaking, it’s a Pumpkin Spice Latte (or "PSL") with White Chocolate Mocha Sauce subbed for half the pumps of Pumpkin Sauce. Take the Cinderella Latte, for instance, which recently re-emerged as a Starbucks secret menu fave. You have to know exactly what you’re asking for, pump for pump. The thing is, unlike the In-n-Out Burger “secret” menu, these off-menu recipes aren’t officially published by Starbucks, and not every barista will know them by heart.

With more than 62,000 tags on Instagram, the #starbuckssecretmenu isn’t particularly secret. Investors are expected to vote on the resolutions at each company’s 2018 annual meeting of shareholders. "When these profits appear to be derived wholly from price hikes, it raises concerns among those of us who care about access to, and the affordability of, medicines - particularly for vulnerable populations like women, children and seniors.” “Our goal is to better understand what oversight these pharmaceutical company boards are exercising when executive incentives are tied so closely to profits," said Cathy Rowan, who represents Trinity Health as a member of ICCR. To the degree that executive incentives reflect a company’s mission and growth strategies, this is clearly a critical and material issue for investors.” Our resolution request is very straightforward: an evaluation of how these concerns are being integrated into corporate governance structures. Said Donna Meyer of Mercy Investment Services, “The increased scrutiny around drug pricing and how it is being managed by pharma management has had reputational consequences for the entire industry. The investors view executive incentive programs as a governance tool designed to ensure adequate oversight of risk and alignment of corporate strategies with mission. Scandals over excessive price hikes at several pharma companies have made the pharma industry the target of Congressional hearings, law suits, denials of coverage from insurers and ballot initiatives in several states which would force manufacturers to negotiate the prices of key medicines with government agencies such as Medicare and Medicaid.Īgainst this backdrop, the investors say, companies need to prove to their investors and to the public that they are doing everything possible to control drug prices in order to manage business and brand risk. Daberkow drs, Dpp finance, Northbrook high school tx, N-decane mechanism. Public anxiety over drug prices has soared in recent years as millions of Americans struggle to afford the essential medicines needed to maintain their health. Sean brown super high download, Lmphgxj65, Abunda and aquino tonight 2015. “As investors in these companies, we are concerned that misaligned incentive pay may encourage executives to sacrifice long-term, organic growth from drug discovery for short-term, ‘quick fix’ strategies that may pose business risks,” said Meredith Miller of the UAW Retiree Medical Benefits Trust. ICCR members also filed a separate but similar resolution at Pfizer and Vertex requesting a report on the business risks from rising pressure to contain U.S. The five companies receiving the resolutions are Abbvie, Amgen, Biogen, Bristol Myers Squibb, and Eli Lilly. In 2007 he chaired the professionalism and reputation work stream prior to the publication of the FSA’s Discussion Paper 07/1 and has subsequently provided RDR and change consultancy to a range of providers, fund managers, and intermediaries. The resolution specifically requests a report on the extent to which risks related to public concern over drug pricing strategies are reflected in executive compensation policies, plans and programs. In the resolutions, the investors argue that an executive compensation incentive program reliant on revenue growth solely from drug price increases is a risky and unsustainable strategy. And as experts in reproductive health care, Planned Parenthood health centers often provide family planning services that other safety-net providers simply do. The investors are all members of the Interfaith Center on Corporate Responsibility (ICCR), a shareholder coalition that has been engaging the pharma sector for decades on drug access and affordability. NEW YORK, NY, Wednesday, Decem– Investors today announced they have filed resolutions at five major pharmaceutical companies asking for information about how well executive pay incentives mitigate long-term financial risks associated with mounting public concerns over the affordability of prescription medicines. drug makers, investors request a review of compensation policies that may drive senior execs to ignore the long-term business risks of skyrocketing drug costs.

Having two-step login enabled for websites and applications is always better than not having it enabled. do not use the Bitwarden Authenticator to protect your Bitwarden account.) Therefore it is currently protected with a high level of security and, in fact, two-step login. Your Bitwarden Vault hopefully already has two-step login using some other method. Of course, some may ask what is the point of having your username, email, and your two-step login code all stored within the same application - namely Bitwarden? Doesn’t that negate the value of two-step login? Note that this feature is only enabled if you do NOT select the “Enable Autofill on Page Load” option in Bitwarden Settings > Options You can then quickly paste it for the final login step. NOTE: If you are using the Bitwarden Authenticator, on completion of autofill, Bitwarden will automatically copy the six digit verification code to your clipboard. You can also retrieve the time-based authenticator code from the Bitwarden app, extension, or from the clipboard (if you’re not using password auto-fill). This code is auto-copied to your clipboard when performing autofill operations in the app. Then, when you use Bitwarden to login to the website/application thereafter, once you enter your username/password and are prompted for the authenticator time-based code. Alternatively, you can also add the text string format version of the authenticator key to the Bitwarden vault entry for that website/application. When you set up two-step login within a website or application and are presented with the QR code referenced in step 2 above, you can scan it with the mobile version of Bitwarden and add it to the login information within the Bitwarden vault for that site. Using the Bitwarden Authenticator to autofill the TOTP code can be set up if the web service supports third party authentication apps such as Authy and Google among others. This uses the Bitwarden Authenticator, built into the Bitwarden application and part of Premium Features. Using the Bitwarden Authenticator with external accountsīitwarden also allows you to manage and facilitate two-step login for individual websites and external accounts stored within your vault. That code will change to a new code every 30 seconds on both the Authenticator app and within the website/application login system, thus providing more security than just receiving a verification code via email or text message. The next time the user goes to login to the website/application, it will prompt not only for username/password, but then also for the time-based 6-digit code. These are usually 6-digit codes that last for 30 seconds. The user now has an Authenticator app that is enabled with the shared secret to generate Time-based One Time Passwords. Now both the Authenticator app and the website/application that will use two-step login have a shared secret. The user scans the QR code using their camera with the Authenticator application they downloaded to their phone or tablet. If for some reason the QR code does not work, the authenticator key is often made available as a long text string. The website shares an authenticator key as a QR code. The user accesses the website or application where they want to add two-step login and initiates that setup process. The sequence for setting up a website to use an Authenticator app for two-step login generally flows like this: These Authenticator applications are typically free for users to download to their phones or tablets from app stores, and include products like Authy, Google Authenticator, Microsoft Authenticator, FreeOTP, Aegis, Duo Security and more. Authenticator applications provide another level of security for two-step login, and generally use a technique called a Time-based One Time Password, or TOTP for short. Since 1967, caesium has been widely used in highly accurate atomic clocks. It was first discovered in 1860, and the initial small-scale applications for caesium were as a ‘getter’ in vacuum tubes and photoelectric cells. Francium has no commercial applications but is used in spectroscopy experiments.Donald Bubar, President and CEO of Avalon Advanced Materials Inc., examines the opportunities for caesium production in Canada and potential new technology applications.Ĭaesium (or cesium) is a scarce and little known alkali element that is usually only found in low concentrations in bedrock. Caesium is used in drilling fluids in the petroleum industry.Rubidium ions are used in purple fireworks.Rubidium and caesium are used in atomic clocks.Potassium-sodium alloys are used in fast breeder nuclear reactors.Potassium finds its application as fertilisers in agriculture.Pure Sodium is also used in sodium-vapour lamps.Sodium in the form of sodium chloride is highly used as table salt.Metallic lithium is used in alloys with magnesium and aluminium to increase their strength and make them light.Lithium finds huge applications in lithium-ion batteries.Hydrogen is quite frequently used in power stations as a coolant in generators.The falling melting and boiling points down the group is dues to the increase of atomic radii or atomic size down the group.The reactivity increase down the group due to the combination of two factors: the first ionisation energy and atomisation energies of the alkali metals.The factors causing decreasing ionisation enthalpy down the group are nuclear charge, the amount of shielding by the inner electrons, and the distance from the most loosely held electron from the nucleus.The atomic radii of group 1 elements increase down the group due to the shielding effect.These sulphates can also be reduced by Carbon to sulphides. Sulphates of alkali metals except for lithium are soluble in water.The nitrates of these elements are soluble in water and on heating they decompose to nitrites(except lithium nitrate).The hydroxides of these metals react with carbon dioxide to give carbonates.They react with hydrogen at high temperatures to form metallic hydrides.Alkali metals react with oxygen gas, while being heated, to produce white solid metal oxides.Alkali metals react with water to produce a metal hydroxide solution and hydrogen gas.Now, let’s discuss the properties of group 1 elements which are physical properties and chemical properties. Properties of Group 1 Elements or Alkali Metals The first elements to be discovered using the spectroscope are rubidium and caesium.įrancium was discovered in France by Marguerite Perey in 1939, by purifying a sample of actinium-227, which had been reported to have decay energy of 220 keV. This was done by deriving it from caustic potash by the use of electrolysis of the molten salt with the newly invented voltaic pile. Humphry Davy was the first to isolate pure potassium, in 1807. Experimental evidence suggesting the fundamental difference of soduium and potassium salts was obtained by Georg Ernst Stahl in 1702. Sodium compounds have been known since ancient times, in the form of salt. Lithium was discovered by Johan August Arfwedson while working in the laboratory of Jons Jacob Berzelius in 1817 when he detected the presence of a new element while analyzing the petalite ore(LiAlSi 4O 10). The element was given its name by Antoine Lavoisier, in 1783, when he and Laplace reproduced Cavendish’s finding that water is produced when hydrogen is burned. Before that Robert Boyle discovered and described between iron filings and dilute acids, which produced hydrogen gas as a result in 1671. Hydrogen gas was first recognized as a discrete substance, by Henry Cavendish in 1766.
