Abstract In Brief Understanding the physiology behind the regulation of body weight can help clinicians treat and educate obese patients.
Drumbeat, at least in theory, had been planned as far back as 1897. Germany had always been fascinated with attacking America , a land insulated and buffered by two oceans. There was a desire to “break” this immunity. Thus, in 1897, when Hitler was a mere boy of eight years, the German military planners first proposed a mostly naval operation against the East Coast of the U.S. Planning continued and by 1898, a more detailed vision had been constructed that focused on a naval bombardment and landing troops on Long Island along the Chesapeke Bay.
“Would you tell me, please, which way I ought to go from here?” “That depends a good deal on where you want to get to,” said the Cat. “I don’t much care where –” said Alice.
To optimize our selection strategy, taking into account the different utilities of all the possible candidates, let us assign a weighting factor g(v) to each candidate. One simple weighting factor is to simply set g(v) = v, which is to say, we assign a value of 1 to candidate “1”, and we assign a value of 2 to candidate “2”, and so on. What is the expected value of goodness for any given strategy? Since we’ve set g(v) = v, this will also give the expected value of v. Obviously with k = 0 or k = 7 (corresponding to the strategies of always choosing the first candidate or always choosing the last candidate, respectively), we have an equal probability, 1/N, of selecting each of the N candidates, so the expected value is <p style="text-align:right;color:#A8A8A8"></p>
post written by: Marc Email It’s fairly easy to find a well written book or online article. But it’s not always easy to find one with genuine value that you connect with. That’s because, these days, books and online articles are a dime a dozen.
I t was January 2010, and investigators with the International Atomic Energy Agency had just completed an inspection at the uranium enrichment plant outside Natanz in central Iran, when they realized that something was off within the cascade rooms where thousands of centrifuges were enriching uranium. Natanz technicians in white lab coats, gloves and blue booties were scurrying in and out of the “clean” cascade rooms, hauling out unwieldy centrifuges one by one, each sheathed in shiny silver cylindrical casings. Any time workers at the plant decommissioned damaged or otherwise unusable centrifuges, they were required to line them up for IAEA inspection to verify that no radioactive material was being smuggled out in the devices before they were removed. The technicians had been doing so now for more than a month. “We were not immune to the fact that there was a bigger geopolitical picture going on.
Posted on Thursday June 18, 2009 by Staff Writers By Sarah Russel Unless you’re enrolled at one of the best online colleges or are an elite member of the science and engineering inner circle, you’re probably left out of most of the exciting research explored by the world’s greatest scientists. But thanks to the Internet and the generosity of many universities and online colleges , you’ve now got access to the cutting edge theories and projects that are changing the world in this list below. If you’re looking for even more amazing lectures, check out our updated list for 2012 with more talks from great minds. General
Neuroscience studies a very complex system: the brain. Much has been learned through formal research of the brain, especially due to the advent of brain imaging technologies which afford increased breadth of research using human subjects. That said, what we know remains very limited, given the complexities of both the organ and the practical application of research findings. However, we can point to six findings that give us new and profound insight into our grey matter. 1.
Sanger method of DNA sequencing Fred Sanger developed the first technique for sequencing DNA. DNA is replicated in the presence of chemically altered versions of the A, C, G, and T bases. These bases stop the replication process when they are incorporated into the growing strand of DNA, resulting in varying lengths of short DNA. These short DNA strands are ordered by size, and by reading the end letters from the shortest to the longest piece, the whole sequence of the original DNA is revealed.
From Sand to Processor or How a CPU is made It is hard to believe that a modern processor (CPU) is the most complex product in the world. What is so complex in this piece of metal? In this article I will try to explain how a modern processer (CPU) is made from the sand. Processor Manufacturing It takes about $ 5 billion dollars to build a processor manufacturing factory.
“We have more possibilities available in each moment than we realize.” - Thich Nhat Hanh Post written by Leo Babauta . I’m not a Zen monk, nor will I ever become one. However, I find great inspiration in the way they try to live their lives: the simplicity of their lives, the concentration and mindfulness of every activity, the calm and peace they find in their days. You probably don’t want to become a Zen monk either, but you can live your life in a more Zen-like manner by following a few simple rules.
Core abdominal muscles are often referred to a variety of exercises. “Keep your core pulled in!”, “Engage your core!”, and “Tighten up your core!”, are all common commands in fitness and workout classes. So what exactly are they talking about?
Animation showing a six-position Geneva Drive in operation The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation into an intermittent rotary motion. The rotating drive wheel has a pin that reaches into a slot of the driven wheel advancing it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps.
