BACKGROUND: Clinical specimens are routinely fixed in 10% buffered formalin and paraffin embedded. Although DNA is commonly extracted from fixed tissues and amplified by PCR, the effects of formalin fixation are relatively unknown. Formalin fixation is known to impair PCR, presumably through damage that blocks polymerase elongation, but an insidious possibility is error prone translesion synthe...

This contribution is devoted to the study of positional numeration systems with negative base introduced by Ito and Sadahiro in 2009, called (−β )-expansions. We give an admissibility criterion for more general case of (−β )-expansions and discuss the properties of the set of (−β )-integers, denoted by Z−β . We give a description of distances within Z−β and show that this set can be coded by an...

In this paper we extend the Balian-Low type theorems to Riesz bases for systems of many signals. We present the construction of coherent frames and we give su cient conditions for these frames to have coherentduals. Under these conditions we prove some nonlocalization theorems.

We present protocols for speeding up fixed-base exponentiation and variablebase exponentiation using an untrusted computation resource. In the fixed-base protocols, the base and exponent may be blinded. If the exponent is fixed, the base may be blinded in the variable-base exponentiation protocols. The protocols are the first ones for accelerating exponentiation with the aid of an untrusted res...

In this work we introduce a practical use of synthesized Schiff base metal complex in sensing application. A new perchlorate-selective electrode based on the complex N, N'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (II) [CuL] as the membrane carrier was developed. The electrode exhibits a good  Nernstian slope of -55.0 ± 1.0 mV/decade and a linear range of  for perchlorate. The lim...

In this paper, the size dependent behavior of the gold micro-switches has been studied. This behavior becomes noticeable for a structure when the characteristic size such as thickness or diameter is close to its internal length-scale parameter. The size dependent effect is insignificant for the high ratio of the characteristic size to the length-scale parameter, which is the case of the silicon...
