If you are concerned, your doctor should be able to check other markers of health, including blood pressure and blood work, to give you a more complete picture about what might be going on. The prescription? Use your BMI as an easy reference point – but if you’re telling yourself that you’re OK despite being over the acceptable range, perhaps check your waist circumference with a tape measure (the British Heart Foundation has a handy guide) or do a body fat test using smart scales or hydrostatic, or underwater, weighing. The problem is that it’s been overvalued or used in isolation and misinterpreted historically by health professionals, and that does need to change.” “In terms of simplicity and speed, and to prompt further action, whether that’s an immediate lifestyle change or further testing, it could be argued that BMI has a place. “A lot of the other ways of measuring body fat are more involved – for instance, a Dexa scan or skin calipers,” says Hodzovic. The real concern is body fat: having too much, particularly around the waist and internal organs, is a risk factor for cardiovascular disease, diabetes and several cancers. “ One US study based on more than 13,000 people suggests that if you are obese according to BMI, you are most likely obese according to body fat percentage as well.” This means that if your BMI goes over (or under) the NHS-approved “healthy” range, it’s probably worth investigating further. “A lot of people who lift weights tend to use ‘muscle’ as an excuse for having a higher BMI even if they also have excess body fat – which is the actual risk factor,” says Hodzovic. So BMI’s pointless as a measure if you go to the gym a lot? Not so fast. It also doesn’t take sex differences into account.” “Muscle is more dense than fat, so in theory you can have a high BMI and still not be obese according to your body fat percentage – though it’s also worth noting that people can have a ‘normal’ BMI and be obese according to body fat if they have low muscle. “As with any tool, it’s only as good as its interpretation and it does have flaws,” says Emil Hodzovic, a doctor and health coach. Obviously, this doesn’t work as well as a measure for children, old people or pregnant women, but where things get trickier is among groups with higher muscle mass and bone density, who can often be classed as “obese” or “overweight”, even when they are sporting a well-defined six pack. According to the NHS, a calculation in the healthy weight range is between 18.5 and 24.9 – though this can differ slightly among ethnic groups. To get the basics out of the way, your BMI is simply your mass (in kilos) divided by the square of your height (in metres), expressed in the units kg/m2. So is it time to throw it out altogether, or can it still tell us something useful about our health? Two centuries later, plenty of experts will tell you that it doesn’t exactly work as advertised either. But Quetelet never intended the measure as a means of medical assessment. That’s what BMI, the body mass index, was known as when the statistician and sociologist Adolphe Quetelet devised it in the 1830s. If I were writing about 200 years ago, the title of this column would be Should I worry about my Quetelet Index?.

When I signed my company up to take the various cards, the contract always had words like that in it. That may end up being the case, but it doesn't sit right with me, since if the manufacturer won't communicate about a quickly-failed product, the CC company is the only real leverage you have left and they can unilaterally take your money back from Rad's CC accounts I think. Seems janky to me and a BK declaration wouldn't be too much of a surprise at this point. If service is just temporarily messed up due to layoffs, that still doesn't explain recordings that say "we're not taking calls" rather than "service calls will take longer than usual to be handled." Again, not an attorney, but if I was in that position as a customer I'd start looking into this right away so you can at least know what your options are. I'm not an attorney, but I believe that if you have a service problem or an unresolved refund, and Rad enters bankruptcy, that everything just stops and you get put onto a list of unsecured creditors with little to no chance of getting anything done as the secured creditors will have first access to any remaining funds or assets. Has anybody in need of service support tried calling the main sales line to see if anybody answers and/or has any idea what's going on at Rad? If they answer, it should be easy to put them on the spot about the apparently shoddy management of after-sale support.Īnybody getting hosed would be within their rights to demand a credit-card refund (credit-card companies can do this unilaterally by contacting them if you can't get Rad to respond) and if Rad objects, tell them to come pick it up since they won't even answer the phone!

In this second example, cell types X and Y are plotted relative to the smallest mean gene expression (cell type B) and the largest mean gene expression (cell type A).Reach your organization’s most important business and technical outcomes.īecome a product and methodology expert and advance your career. If instead the dot plot has more cell types, for example, cell type A has mean gene expression of 4 for the gene of interest and cell type B has mean gene expression of 0 for the gene of interest, then A and B would be set to the "1" and "0" ends of the scaled mean expression, respectively. While Y, having the smallest value, means the "0" end of the scaled mean expression corresponds to a mean gene expression value of 1 (ie the dot for cell type Y will be blue). IF the dot plot has ONLY cell types X and Y, because X has the largest value, the "1" end of the scaled mean expression bar corresponds to a mean gene expression value of 2 (ie the dot for cell type X will be red). Scenario: in cell type x the mean gene expression of gene “random” is 2, and in cell type y the mean gene expression of gene “random” is 1 Example 1 "scaled mean expression" gives a visual indicator of where each cell type's mean gene expression lands relative to the smallest and largest mean gene expression for the gene of interest across the cell types shown in the dot plot.

The updated implementation performs the following: There's a writeup on how this is implemented in OSX here by an Apple engineer: There is an user-land patch here: by which might help as a workaround. What is the feature you are proposing to solve the problem? Restarting the router resolves the issue. I have noticed that Node 17 will then pretty much hang on outgoing connections for up to one minute before eventually being able to connect. More on this here: square/okhttp#6954 (comment) The problem is that consumer routers sometimes glitch out on IPv6.Ī router I manage in one particular location, which is a consumer grade TP-Link router, will routinely hang on IPv6 connections about once per month, until it is restarted. In particular, there are a lot of data points related to similar support lacking from the OkHttp library which is used heavily on Android and results in connectivity issues for a relatively big number of users. The lack of Happy Eyeballs support can result in connections failing. It appears that node 17 has merged this PR: #39987 which may result in IPv6 addresses being sorted first.Īs per an answer in this reddit thread from it appears that Happy Eyeballs is not implemented however. *And as clever as Happy Eyeballs might be, its co-author Andrew Yourtchenko might be at least as well known for this amusing video.What is the problem this feature will solve? More troubling for the cause of IPv6 adoption is perhaps found in Emile Aben’s (of RIPE) article on the same topic where he discovers that the Mac OS X implementation of “happy eyeballs” leaves available and working IPv6 resources under-preferred in half the tested cases resulting in a condition he dubs “hampering eyeballs.”Īs we head into the new year with the promise of another World IPv6 event as well as more users and content than ever before connecting to the Internet via IPv6, “happy eyeballs” looks poised to help solve one outstanding problem while, depending on how it gets implemented, perhaps creating some new ones. He also discovers some instances where performance suffers to the same degree of poor IPv4 fallback–namely, where a responsive resource address exists among multiple inactive addresses (resulting in more than 75 seconds of transaction latency). APNIC’s chief scientist Geoff Huston has a humorously-titled analysis (don’t believe me? click here) that digs into what’s going on under the hood. So far, at least Mac OS X and Chrome have instituted some variant of it and the results are quite impressive (consistent sub-second performance times even with broken IPv6 connectivity). (Also refreshing is the implied presumption that IPv4 can be just as broken as IPv6 might be!). The basic idea is immensely clever* in its disregard for the logic of the prevailing standard of RFC3484 and IPv4 fallback: for an application connecting to a web-based resource, name resolution to IPv4 and IPv6 addresses (as well as any subsequent connections to those addresses) should occur in parallel with the connection to the best performing address persisting while the runner-up is politely ignored or reset as needed. Happy Eyeballs, the IETF draft promising a snappy application connection to the best performing address family whether IPv4 or IPv6 (as well as an organic free-range chicken in every pot and an electric car in every garage) would seem to be, if not a definitive solution to the long-standing “ IPv6 brokenness” issue, then at least a great leap forward. Alternatively, if I’m holding my attack key and I tap my movement key, my character needs to move.

In essence, that's the purpose of Automatic Mouse and Keyboard: upon recording your actions, the app will save them for you to automate later. If you ever wanted to automate certain keystrokes and button combinations, you likely wondered if there are apps that would do that for you. He can't tell how long it was between the stabbing and the taxi running him over, but does know that the incidents weren't immediate. Doc Robbins notes that there's a stab wound to the victim's abdomen. Grissom concludes that the boy wasn't hit by the taxi, but he was run over as he was lying on the ground. The victim's chest was crushed and he has multiple rib fractures. In autopsy, Doc Robbins tells Grissom that the victim didn't sustain any bruises or fractures to the lower extremities, which is usually common with someone involved in a hit-and-run. Grissom collects his clothes and brings them to Greg in the lab. She says that he's in critical condition with a ruptured spleen, collapsed lung, fractured ulna, and intracranial bleeding. Grissom visits the hospital and talks to Rajeeb's nurse. The mob initially refuses, but relents after Brass threatens to bring them to the police station. Grissom demands DNA and a photo from each. Brass interviews the xenophobic mob, who claim they're heroes for defending their country, but Brass isn't impressed. She cannot identify a specific assailant, but knows that the mob standing nearby is guilty of beating up Rajeeb. The passenger says the taxi driver wasn't trying to run away, but rather use his radio to call for help. Neither he nor Brass have seen this in a hit-and-run victim before. Grissom and Brass arrive at the scene, and Grissom notices the boy's internal organs are hanging out. Rajeeb panics and gets out of the taxi, but when he appears to get back in to flee, a nearby mob beats him severely. A boy hobbles out in front of the taxi and is struck, pinning the body under the wheels. On the case: Gil Grissom, Sara Sidle, Jim BrassĪ taxi driver, Rajeeb Khandewahl, is talking to his female passenger while driving, more focused on the woman's looks than the road in front of him. Victims: Todd Branson (deceased), Rajeeb Khandewahl (alive) Grissom and Sara later find the primary crime scene at a basketball court, where they discover the body of a man who was shot to death. When Grissom arrives at the scene, he finds out that the boy was already dying from a stab wound. A taxi driver is beaten to death by a mob after running over a boy with his taxi.

The essence of this subject is the careful and compact statement of the conservation principles, along with the flux expressions, with emphasis on the similarities and differences among the three transport processes considered. Long regarded as a rather mathematical subject, transport phenomena is most important for its physical significance. Designation of some sections as optional (0) and other as advanced (a) may be helpful to students and instructors. The elementary course, in turn, can be divided into one course on momentum transfer, and another on heat and mass transfer, thus providing more opportunity to demonstrate the utility of this material in practical applications. Enough material has been included for two courses, one introductory and one advanced. Moreover, we have found in discussions with colleagues that transport phenomena is taught in a variety of ways and at several different levels. While we have included many representative examples, our main emphasis has, of necessity, been on the fundamental aspects of this field. Evolution of transport phenomena has been so rapid and extensive that complete coverage is not possible. This development, in turn, less than half a century old, continues to grow and to find applications in new fields such as biotechnology, microelectronics, nanotechnology, and polymer science. W h i l e momentum, heat, and mass transfer developed independently as branches of classical physics long ago, their unified study has found its place as one of the fundamental engineering sciences.
