Even though. since the 1970s,Auschwitl has eclipsed Dachau as the most widely recognized symbol of Nazi atrocities, the Dachau concentration camp museum remains by far the most visited original site associated with Nazi Germany. With the annual number of visitors rising from ca. 100,000 in the early 19505 to peak at just under 1 million in the late 19805. the Dachau memorial site museum ranks a...

We consider reshaping an obstacle virtually by using transformation optics in acoustic and electromagnetic scattering. Among the general virtual reshaping results, the virtual minification and virtual magnification are particularly studied. Stability estimates are derived for scattering amplitude in terms of the diameter of a small obstacle, which implies that the limiting case for minification...

Objectives: The SMART study is a three-year, longitudinal, multicenter evaluation comparing corneal reshaping contact lenses (CRCL) influence on the progression of myopia in children (age 8 to 14 at enrollment) to the wearing of soft silicone hydrogel contact lenses (SCL) worn on a daily wear basis with monthly replacement. This study represents one of the largest patient enrollment with ten in...

In the past few decades, huge surges and waves generated during tsunami events have caused devastating destruction to both onshore offshore infrastructures, seriously threatening safety intactness of coastal communities around world. As one most important protection a seawall can effectively reduce impact intensity waves, thus playing vital role in protecting regions. Most previous studies syst...

The Coulomb interaction among massless Dirac fermions in graphene is unscreened around the isotropic Dirac points, causing a logarithmic velocity renormalization and a cone reshaping. In less symmetric Dirac materials possessing anisotropic cones with tilted axes, the Coulomb interaction can provide still more exotic phenomena, which have not been experimentally unveiled yet. Here, using site-s...
