    1. A simplified freezing point depression (FPD) equation was derived for calculating water activity (aw) of food systems. The aw values as calculated by FPD data agreed with literature data for a variety of foods to within ± 0.01 aw units. The FPD equation was found particularly useful for calculating aw values of frozen foods at temperatures between 273.1.5–233.15 °K (0 to −40°C).

      ± 0.01 aw? That's crazy accurate. Temperature is extremely easy to measure at home, which makes this a perfect technique for home food preservation. In particular, it can be used with sugar-free, salt-free, and other obscure recipes for which water activity is hard to estimate.

      Additionally, this accuracy could be run in reverse. Knowing the water activity of ice-cream can tell you the freezing point. Moreover, a mini fridge could keep select food items chilled below 0°C for better preservation. In particular, I plan to dissolve erythritol into unsweetened plant milks and lower my fridge temp accordingly.

    1. About 1930 it began to be evident that the nerve cell is not physiologically inert, does not have to be excited from outside in order to discharge (19, p. 8). The nervous system is alive, and living things by their nature are active. With the demonstration of spontaneous activity in c.n.s. it seemed to me that the conception of a drive system or systems was supererogation. For reasons I shall come to later, this now appears to me to have been an oversimplification; but in 1945 the only problem of motivation, I thought, was to account for the direction taken by behavior. From this point of view, hunger or pain might be peculiarly effective in guiding or channeling activity but not needed for its arousal. It was not surprising, from this point of view, to see human beings liking intellectual work, nor to find evidence that an animal might learn something without pressure of pain or hunger. The energy of response is not in the stimulus. It comes from the food, water, and oxygen ingested by the animal; and the violence of an epileptic convulsion, when brain cells for whatever reason decide to fire in synchrony, bears witness to what the nervous system can do when it likes. This is like a whole powder magazine exploding at once. Ordinary behavior can be thought of as produced by an organized series of much smaller explosions, and so a "self-motivating" c.n.s. might still be a very powerfully motivated one. To me, then, it was astonishing that a critic could refer to mine as a "motivationless" psychology. What I had said in short was that any organized process in the brain is a motivated process, inevitably, inescapably; that the human brain is built to be active, and that as long as it is supplied with adequate nutrition will continue to be active. Brain activity is what determines behavior, and so the only behavioral problem becomes that of accounting for inactivity.

      New ways to think on motivation and c.n.s. That the views of the past were too simple, and that you don't have to use pain to motivate animals whether lower or high functioning. You can also motivate with food, water, oxygen which causes the energy of response. When prior it was thought stimulus was what caused the energy or response. They noted brain cells fired together in sync, showing us that the nervous system can do what it wants and not just based on stimulus or physical motivation.

    1. What the Internet has done to date is expand the potentiality formore widespread, instantaneous awareness of activity and consequences on aglobal scale. This means that verifiability need not be personal—so long asreliable information can be retrieved from information systems. But havingretrieved the information or having it instantaneously available does not meanthat we have the capacity to act upon it.

    1. The PDMs of this model show promise in revealing the important dynamic characteristics of the underlying physiological mechanisms and allow the formulation of specific quantitative hypotheses about the role of the sympathetic and parasympathetic activity (corresponding to specific PDMs) in cerebral perfusion and autoregulation. Consistent with the widely held view regarding the temporal characteristics of autonomic control of the cardiovascular system, it is posited that the HR PDMs with a resonant spectral peak around 0.2 Hz may be associated with parasympathetic activity, whereas the PDMs with a resonant spectral peak around 0.12 Hz may be associated with sympathetic activity
    1. Of the different instantaneous HRV indices computed by the point process technique, we selected the instantaneous high frequency power (HF) as our representative HRV metric. Heart rate HF power has garnered the greatest consensus for reflecting respiratory sinus arrhythmia (RSA) modulation by parasympathetic activity

    1. I enjoy it as a quiet type of game you can play even when you've had a long, tough day. And I don't mind pulling unusable tiles; at least you get to take another one instead of missing your turn. There's just something relaxing about it. After all, lots of people enjoy sitting for hours playing Patience and this is much more entertaining than that.

    1. “Follow your blisters” implies something that you come back to so many times that you eventually move past the blister stage, into toughened skin. Eventually, the activity “marks you” through use and practice, and you develop a special competence. When you practice an activity a bit more obsessively than other people, you build unique character – you earn some wear and some healing that makes you idiosyncratic, and a little unbalanced.It is something that you don’t need to put on your to-do list, something you care enough about to return to repeatedly, even though it causes discomfort. Over time, you develop a layer of protection that enables you to do that something more easily.
    1. When nesting an activity with multiple outcomes, you can wire each terminus to a different route.
    2. For example, an output using Track(:create) will snap to the next possible task that is “magnetic to” :create. That’s how tracks or paths are created.
    3. Semantics are mostly relevant for nesting
    4. Remember, in a railway activity each task has two standard outputs with the “semantics” success and failure.
    5. By using Output(:semantic), you can select an existing output of the task and rewire it.
    6. Why don’t we put the “create user” task onto the failure track, and in case of successfully persisting the new user, we deviate back to the happy path?
    7. the Activity component is the heart of TRB
    8. To implement such an activity, we only need to rewire the second step’s failure output to a new terminus.
    9. Since you can reference outputs by their semantic, you as a modeller only connect conceptual termini to ongoing connections!
    10. it’s a bit as if the following wiring is applied to every task added via #step
    11. Additionally, you may add debugging steps, error handler or rewire the conditions dynamically without touching the original snippet.
    12. Suppose that the validate task was getting quite complex and bloated. When writing “normal” Ruby, you’d break up one method into several. In Trailblazer, that’s when you introduce a new, smaller activity.
    13. Knowing about the wiring mechanics in Trailblazer is one thing. However, the real fun starts with nesting activities. That’s when the ideas of encapsulation, interfaces and reducing dependencies really come into play.
    14. Nesting an activity into another is a bit like calling a library method from another method
    15. the explicit modelling has one massive advantage: all possible outcomes of the nested activity are visible and have to be connected in the outer diagram

    1. Business Process Model and Notation (BPMN) is a standard for business process modeling that provides a graphical notation for specifying business processes in a Business Process Diagram (BPD),[3] based on a flowcharting technique very similar to activity diagrams from Unified Modeling Language (UML).

    1. Matz, alas, I cannot offer one. You see, Ruby--coding generally--is just a hobby for me. I spend a fair bit of time answering Ruby questions on SO and would have reached for this method on many occasions had it been available. Perhaps readers with development experience (everybody but me?) could reflect on whether this method would have been useful in projects they've worked on.
