The recent PRB 73, 224501 (2006) henceforth referred as Ref.\cite{0} asserts that self-heating decreases with sample area reduction and claims to identify the intrinsic cause of ITS in submicrometre `mesa'. I will show that this assertion lacks subst

The recent PRB, henceforth referred as Ref.[1], experimentally resolves the intrinsic shape of the c-axis current-voltage characteristics (IVC) of HTSC and demonstrates that at sufficiently high heat loads the heating-induced IVC nonlinearities excee

In a recent letter, henceforth referred to as Ref.[1], You et al postulate that Bi2212 factually represents a series array of SIS junctions and claim that the nonlinear current-voltage characteristics (IVC) of their bridge are free of heating. Earlie

Our comprehensive analysis suggests the heating origin of key findings by the authors of the commented letter, hence rendering irrelevant their conclusions.

The author of the comment promotes a brush-like IVC, which is claimed to be free of self-heating. I will show that this claim lacks substantiation as the IVC is definitely not free from heating and that the self-heating cause of IVC-2 is indirectly a

The out-of-plane current-voltage (I-V) characteristics of Bi2212 are studied in experimental environments of different heat transfer efficiency, allowing practical separation of intrinsic and extrinsic phenomena. {\it Intrinsic} (heating-free) respon

High magnetic field studies of cuprate superconductors revealed a non-BCS temperature dependence of the upper critical field $H_{c2}(T)$ determined resistively by several groups. These determinations caused some doubts on the grounds of both the cont

A pseudogap (PG) is believed to be responsible for the non Fermi-liquid normal state of cuprate superconductors. In particular, field induced PG collapse causes negative longitudinal magnetoresistance (MR), for details, see V.N. Zavaritsky, M. Spring

We calculate the Nernst signal in disordered conductors with the chemical potential near the mobility edge. The Nernst effect originates from interference of itinerant and localised-carrier contributions to the thermomagnetic transport. It reveals a
