BACKGROUND Dental amalgam is composed of approximately 50% elemental mercury. Despite concerns over the toxicity of mercury, amalgam is still the most widely used restorative material. Wi-Fi is a rapidly using local area wireless computer networking technology. To the best of our knowledge, this is the first study that evaluates the effect of exposure to Wi-Fi signals on mercury release from am...

Aim: To keep the cervical canal dilated after the fi rst high dose rate (HDR) brachytherapy fraction to avoid general anesthesia during subsequent applications. Patients and Methods: In the fi rst HDR brachytherapy application: examination and cervical dilatation was done under general anesthesia. The proximal 4 cm of urinary Foley catheter was cut (making the new cervical tube), inserted in th...

In this issue of The Lancet, three Series papers and a Viewpoint commemorate 70 years of caring for survivors of the atomic bombings of Hiroshima and Nagasaki, as well as the more recent extension of that care to those aff ected by the Fukushima nuclear accident. As a result of this unwelcome triple legacy, Japan has become a uniquely important site for understanding radiation-related health ef...

Bicircular twisted Laguerre-Gaussian beams possess a definite torus knot angular momentum (TKAM) $\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{{J}_{\ensuremath{\gamma}}}=\stackrel{\ifmmode \^{}\fi{}}{L}+\ensuremath{\gamma}\stackrel{\ifmmode \^{}\fi{}}{S}$ as an alternative form of momentum. TKAM is conserved in nonlinear atomic processes such high harmonic generation and can be classified by time ...

Adaptive radiation is one of the most important outcomes of the process of evolution, and islands are places where it is best observed. The term itself was fi rst used by H. F. Osborn in  in describing parallel adaptations and convergence of species groups on different land masses. Since then, adaptive radiation has been widely recognized and defi ned in multiple ways to emphasize the contr...

The kagome superconductors ${\mathrm{KV}}_{3}{\mathrm{Sb}}_{5}$, ${\mathrm{RbV}}_{3}{\mathrm{Sb}}_{5}$, and ${\mathrm{CsV}}_{3}{\mathrm{Sb}}_{5}$ are known to display charge density wave (CDW) order which impacts the topological characteristics of their electronic structure. Details structural ground states how they evolve with temperature revealed here using single crystal x-ray crystallograph...
