A paper sheet processing apparatus includes: an insertion slot through which a paper sheet is inserted; a sensor which detects insertion of the paper sheet; a traveling route through which the paper sheet is conveyed; a light emitting part which irradiates the traveling route with light; a light receiving part which receives light from the traveling route; a black calibration part which sets a reference value for the lowest brightness in a state that the emission of the light emitting part is ineffective; and an authenticity judgment processing part which judges an authenticity. The black calibration part can set the reference value before the authenticity judgment processing part judges the authenticity after the sensor detects the insertion of the paper sheet at every time when the paper sheet is inserted.

I believe in thank you notes. I believe in sending them and in receiving them. Absolutely for gifts – every gift REQUIRES written acknowledgement – but also for random acts of kindness or thoughtful behavior and for hospitality. Ask anyone, “Hey, how are you doing?” and they will most likely respond, “Busy. I am SOOO busy. There is just too much going on.” People are busy. Everyone is busy. Work. Play. Shopping. Recreation. Family. Cooking. Errands. Laundry. School. Housework. Social commitments. Yard work. Commuting. Volunteering. It’s hard to make time for yourself, much less for others. That’s why it is so darned special when someone takes the time to do something nice. It may be something small, such as checking to see if you have books that need to be returned to the library since they are going. Or something bigger, like inviting you over for dinner because they know you’ve spent the day carting around mulch in the yard and will be too tired to cook. I believe people who make the

(California Court of Appeal) - Held that an arbitrator did not exceed his authority by denying attorney fees to a party that prevailed in an arbitration, under the particular circumstances of this case. Affirmed in relevant part, in a dispute involving an investment made by a retirement plan.

This set of notes focuses on the restriction problem in Fourier analysis. Introduced by Elias Stein in the 1970s, the restriction problem is a key model problem for understanding more general oscillatory integral operators, and which has turned out to be connected to many questions in geometric measure theory, harmonic analysis, combinatorics, number theory, and […]

The square root cancellation heuristic, briefly mentioned in the preceding set of notes, predicts that if a collection of complex numbers have phases that are sufficiently “independent” of each other, then similarly, if are a collection of functions in a Lebesgue space that oscillate “independently” of each other, then we expect We have already seen […]

In contrast to previous notes, in this set of notes we shall focus exclusively on Fourier analysis in the one-dimensional setting for simplicity of notation, although all of the results here have natural extensions to higher dimensions. Depending on the physical context, one can view the physical domain as representing either space or time; we […]

1) Because the quarantine is less hard on me than it is on others, I sometimes forget to give myself a break for the ways in which it is hard. Privilege doesn't mean nothing ever hurts. I'm gonna try to be kinder to myself about all this.

2) I'm now getting two weekly farm boxes. I'm not sorry at all.

3) We've killed off 18.5% of our consumer debt since January. We rock.
