Extended range harmonic filter

Two types of filters, leaky-wall and open-guide, are combined into single component. Combination gives 10 db or greater additional attenuation to fourth and higher harmonics, at expense of increasing loss of fundamental frequency by perhaps 0.05 to 0.08 db. Filter is applicable to all high power microwave transmitters, but is especially desirable for satellite transmitters

Commentary: Challenging Three Electoral College Indictments

On the day the Electoral College met and elected Donald J. Trump the 45th president of the United States, the New York Times editorial board published a scathing attack on the Electoral College as an antiquated mechanism which overwhelming majorities of Americans would prefer to eliminate in favor of a direct national popular vote.

Commentary: California Secessionists Channel Logic of Southern Slaveholders

\u27Thursday night the streets were filled with excited crowds. No one talks of anything but the necessity for prompt action. . . . It is hardly prudent for any man to express his opinion adverse to immediate secession, so heated are the public passions, so intolerant of restraint is the popular will. You would probably assume that this report came from California in the wake of the 2016 election, right? After all, Alex Padilla, the California secretary of state, has now authorized the Yes California Independence Campaign to begin collecting signatures for a state referendum on California\u27s secession from the United States.

In Defense of the Electoral College

There is hardly anything in the Constitution harder to explain, or easier to misunderstand, than the Electoral College. And when a presidential election hands the palm to a candidate who comes in second in the popular vote but first in the Electoral College tally, something deep in our democratic viscera balks and asks why the Electoral College shouldn’t be dumped as a useless relic of 18th century white, gentry privilege. Actually, there have been only five occasions when a closely divided popular vote and the electoral vote have failed to point in the same direction. No matter. After last week’s results, we’re hearing a litany of complaints: the Electoral College is undemocratic, the Electoral College is unnecessary, the Electoral College was invented to protect slavery — and the demand to push it down the memory hole.

Commentary: Will the Courts Make Trump\u27s Presidency Less Imperial?

Nearly three months ago, Donald Trump assumed a presidency that, for more than a century, had grown seemingly endless discretionary powers. And he did so in company with Republican majorities in Congress and in 32 state legislatures -- all of which should have made his decisions unassailable. Instead, he has been stymied and embarrassed by resistance from a federal judiciary that has twice halted executive orders on the most prominent issue of his presidential campaign. So, will the federal judiciary become the wall against which Trump bleeds away the power not just of his own presidency but of the “imperial presidency” we have watched a-building since the days of Teddy Roosevelt?

NVU dynamics. III. Simulating molecules at constant potential energy

This is the final paper in a series that introduces geodesic molecular dynamics at constant potential energy. This dynamics is entitled NVU dynamics in analogy to standard energy-conserving Newtonian NVE dynamics. In the first two papers [Ingebrigtsen et al., J. Chem. Phys. 135, 104101 (2011); ibid, 104102 (2011)], a numerical algorithm for simulating geodesic motion of atomic systems was developed and tested against standard algorithms. The conclusion was that the NVU algorithm has the same desirable properties as the Verlet algorithm for Newtonian NVE dynamics, i.e., it is time-reversible and symplectic. Additionally, it was concluded that NVU dynamics becomes equivalent to NVE dynamics in the thermodynamic limit. In this paper, the NVU algorithm for atomic systems is extended to be able to simulate geodesic motion of molecules at constant potential energy. We derive an algorithm for simulating rigid bonds and test this algorithm on three different systems: an asymmetric dumbbell model, Lewis-Wahnstrom OTP, and rigid SPC/E water. The rigid bonds introduce additional constraints beyond that of constant potential energy for atomic systems. The rigid-bond NVU algorithm conserves potential energy, bond lengths, and step length for indefinitely long runs. The quantities probed in simulations give results identical to those of Nose-Hoover NVT dynamics. Since Nose-Hoover NVT dynamics is known to give results equivalent to those of NVE dynamics, the latter results show that NVU dynamics becomes equivalent to NVE dynamics in the thermodynamic limit also for molecular systems.Comment: 14 pages, 12 figure

Using rewards and penalties to obtain desired subject performance

Operant conditioning procedures, specifically the use of negative reinforcement, in achieving stable learning behavior is described. The critical tracking test (CTT) a method of detecting human operator impairment was tested. A pass level is set for each subject, based on that subject's asymptotic skill level while sober. It is critical that complete training take place before the individualized pass level is set in order that the impairment can be detected. The results provide a more general basis for the application of reward/penalty structures in manual control research
