We introduce the concept of regular super-functions at a fixed point. It is derived from the concept of regular iteration. A super-function F of h is a solution of F(z+1)=h(F(z)). We provide a condition for F being entire, we also give two uniqueness criteria for regular super-functions. In the particular case h(x)=bˆx we call F super-exponential. h has two real fixed points for b between 1 and...

Refractory multi-element alloys (RMEA) with body-centered cubic (bcc) structure have been the object of much research over last decade due to their high potential as candidate materials for high-temperature applications. Most these display a remarkable strength at temperatures, which cannot be explained by standard model bcc plasticity dominated thermally-activated screw dislocation motion. Rec...

In order to study the initial corrosive changes of dental casting alloys in the mouth, the condition and composition of the proximal surface of the class II inlay were analyzed by the scanning electron microscope (SEM) and the electron probe microanalyser (EPMA). These analyses on the same small areas of the proximal surface were carried out every week for four weeks. The results were compared ...

We consider the two-loop four-point amplitude in N = 2 super QED, and show that there exists an approximate recursive structure similar to that captured by the ABDK/BDS ansatz for MHV amplitudes in N = 4 super Yang-Mills. Furthermore, we present a simple relation between the box coefficients of one-loop photon MHV amplitudes in (super) QED, and sums of box coefficients of one-loop MHV amplitude...

Clinical isolates of meticillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Candida albicans and Mycobacterium tuberculosis (MTB) were tested against copper (Cu) and its alloys. Stainless steel and polyvinylchloride (PVC) were used as controls. The amount of Cu required to inhibit test isolates at room temperature (24 degrees C...
