We'll use synthetic fuel in airplanes. It's going to require some major technological breakthroughs before battery powered airliners are practical.
Hydrogen and synthetic hydrocarbons are also handy in rockets, as a storage medium for solar and wind power, and as a convenient method of moving electricity long distances.
It's possible to do modification on only certain cells in the embryo. But it's a lot of work, and requires that you wait until the embryo has developed enough to have cells that are differentiated enough to be destined to be only what you want.
These were pre-implantation embryos. Basically, balls of undifferentiated cells. So their modification would almost certainly be present in all cells (including germ cells) if the embryo were allowed to develop.
Meh, I'm sure there will be a much cheaper Chinese one made soon. Small camera drones are getting pretty cheap, and the algorithms to control it are all open source. You could probably build yourself one for less than half the price they were charging. Perhaps less than a quarter if you used a cell phone to do the command and control.
No, it's not quite the same thing, although the concepts are related. In this case, reconstructing your signal is still limited by the Nyqvist frequency of course, but your ability to reconstruct across the ADC reset discontinuities also requires that the amplitude doesn't change so fast that you get more than one wrap per sample period.
I suspect it actually is the Nyqvist limit, but applied in this weird phase, er, amplitude unwrapping situation.
Ha ha... there's a cartoon on the window of a lab down the hall, showing how to get a paper accepted in an IEEE journal. You start with something like 1 = 1 and end up with a page of math.
I've personally gotten this review back from IEEE TSP: "too many words, not enough math."
My impression is that this won't really help, because the ability to reconstruct the signal is limited by the highest frequency in the signal and the sampling frequency.
If your signal rises too fast relative to your sampling frequency you can't reconstruct it across the phase... amplitude wraps. So you can use this trick with a faster sampling resetting ADC, or you can use a slower sampling regular ADC with a higher resolution. As the OP points out, making higher resolution ADCs is a more mature process than making resetting ADCs.
I found the idea of using a resetting ADC that counts the number of resets more interesting, but the authors discard that as "requiring extra circuitry" right at the beginning of the paper.
As far as I can tell, they've done some math to put bounds on how fast the signal can change (how high a frequency can be present) to allow reconstruction. That there is a limit is pretty intuitive, since if you signal changes slowly enough (relative to your sampling frequency) then you can easily identify and count each reset.
It seems to me that would work fine in things like audio recorders, but won't work so well in things like cameras.
If inflation is correct, and the basic premise at least seems very likely to be, then no, at 5 minutes old the speed of light would have seemed almost as slow as it does today. At any time after 10-33 or so seconds after the bang, light would seem as slow as it does today.
Easier to just buy an actual bank. Or, since you like to have "phat cash reserves" on your balance sheet, just buy enough stock for a controlling interest in one.
Maybe it's different in the US, but this is pretty much already done. I do most of my banking through the financial services arm of what used to be a grocer. One of my relatives works as an analyst for the financial services arm of a national chain of hardware and automotive stores.
In this case it's almost certainly being invested by the companies themselves. Apple's "cash" reserves are mostly in the form of long-term marketable securities.
That's really the way it's supposed to work: the public takes the big risks and does the things that are not economically justifiable. When the endeavour becomes more routine, commerce takes over, and the public goes on to the next frontier.
SpaceX isn't really such a good counter to that. They benefitted from around a century of government research into rocketry, aerospace and space flight, as well as lots of government subsidies. Their biggest customer is one of the biggest governments in the world. And although they're doing it in very innovative ways, they're serving a pretty well-established market.
You're suggesting that we should allow for the possibility that vehicle safety will come to depend on a paid service from a cable company. And calling other people morons.
Your brain always needs sugar. Your brain is basically dependent on glucose for energy. Your body can manufacture that glucose from breaking down protein, but it still has to become glucose somewhere along the line.
That doesn't mean eating sugar with a spoon will make you smart.
Sugars are macronutrients. You need lots of them. This is opposed to micronutrients, which are what your mother refers to when she says "it's nutritious!"
You don't technically need carbohydrates in your diet (probably, I'm not sure anyone has ever actually achieved a zero carb diet for any length of time) because your body can break down other macronutrients, like protein, to make them. But it's kind of a dirty process and it won't make you feel very good.
Most reasonable sources agree that a healthy diet includes about 1/3 of its calories from carbohydrates. The problem is, the majority of westerners get much more than that.

Not if the company management has an incentive to always make sure the pre-IPO valuation is unreasonably high.
The companies are getting those valuations from the VCs by agreeing to terms that protect the VCs and screw all the smaller investors.
That scenario is about detecting defects. I hate to tell you, but that ship sailed about a decade ago.
This article is about *fixing* those defects.

Does it involve blue goo and Vulcans?
Precisely. Only when users solve their storage utilization problem by deleting the bloated software will it become a problem for the engineers.
Yeah. Time to switch back to safari.

But you gain the ability to correct motion or other artifacts, and increase dynamic range, which is why the technique is used in astrophotography.
If you've got more bits you change the gain on your amplifier to translate that into more range.
Saturation is saturation, which is irrelevant if you're using a type of ADC that resets instead of saturating.

US customs agents have been stationed in Canadian airports for decades. I assumed the reason they didn't do this overseas was more due to cost.
