Changes in CDL Rules and Regulations and What It Means For You

The CDL application process is changing. The DOT’s Federal Motor Carrier Safety Administration (FMCSA) will now have a registry of approved trainers that entry-level truckers must use, Class A and Class B CDL applicants will have separate standards, and there are new requirements for certain endorsements. Potential drivers will have to wait longer to get in a truck and start making money, and for some the training will be cost-prohibitive. Join us for a discussion

Alternate Methods for Preserving Asphalt Pavements

Come hear how the city of Warsaw, Indiana, uses a “mix of fixes” to economically extend the life cycle of its road network while maintaining a safe and politically friendly high pavement condition index (PCI) number. The mixes include rejuvenation, slurry, micro, and crack sealing

The Telegraph Goes to War: The Personal Diary of David Homer Bates, Lincoln\u27s Telegraph Operator

Modern technology The White House connection At first glance this appears to be a book with no clear raison d\u27etre, other than being about the Civil War, a subject of such endless fascination to American readers that, as one current historical authority has put it, no book...

Disordered Ultracold Two-Dimensional Bose Gases

Ultracold bose gase systems can perform quantum simulations of high temperature superconductors in certain parameter regimes. Specifically, 2D bose gases at low temperatures exhibit a superfluid to thermal gas phase transition analogous to the superconductor to insulator transition in certain superconductors. The unbinding of thermally activated vortex pairs drives this phase transition, and disorder is expected to affect vortex motion in this system. In addition, disorder itself can drive phase transitions in superconductors. We have designed and built a system which produces two 2D ultracold Bose gas systems separated by a few microns. In addition, we have also produced a disordered speckled laser intensity pattern with a grain size of ~1 μm, small enough to provide a disordered potential for the two systems. We have observed the superfluid phase transition with and without the presence of disorder. The coherence of the system, which is related to superfluidity, is strongly reduced by the presence of disorder, even at small disorder strength, but the effect of the disorder on observed vortices in the system is less clear
