The investigation into airborne fungal spore concentrations was conducted in Szczecin (Poland) between 2004 and 2009. The objective of the studies was to determine a seasonal variation in concentrations of amerospores on the basis of meteorological parameters. The presence of spores in Szczecin was recorded using a volumetric method. Fungal spores were present in the air in high numbers in late...

The denaturation transition which takes place in circular DNA is analyzed by extending the Poland-Scheraga (PS) model to include the winding degrees of freedom. We consider the case of a homopolymer whereby the winding number of the double-stranded helix, released by a loop denaturation, is absorbed by supercoils. We find that as in the case of linear DNA, the order of the transition is determi...

1 Comment on " Why is the DNA denaturation transition first order? " Recently, Kafri, Mukamel and Peliti (KMP) [1] extended the classical Poland-Scheraga (PS) model for the denaturation transition of DNA [2]. According to PS, the energetic binding of bases in the double helix competes with the entropic contribution of denatured loops, implying that the nature of the transition depends on the ex...

The Poland-Scheraga (PS) Model is one of the most celebrated applications of statistical physics to biology. By relying on basic laws of statistical phase transitions the PS model describes the denaturation of DNA strands as a function of temperature according to a minimal set of assumptions. The basic model makes the prediction of a second-order phase transition in the order parameter of the s...
