Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Metaplectic Wigner Distributions
Metaplectic Wigner distributions were recently investigated as natural generalizations of the classical Wigner distribution, and provide a wide class of time-frequency representations that exploits the structure of the symplectic group. This work serves as a survey on metaplectic Wigner distributions and their applications to the time-frequency ...

Research Paper: Non-Classicality Indicators of Entangled and Squeezed Number States [PDF]
فیزیک کاربردی ایرانMany non-classicality indicators are used to measure the quantum effects of different systems. Kenfack's and Sadeghi's non-classicality indicators are introduced regarding the amount of Wigner distribution function's negativities and interferences in ...

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations
Smart Molecules, EarlyView.Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Wigner distribution reconstruction from two projections
, 2001 The connection between the instantaneous frequency and the angle derivative of the fractional power spectra is established. It permits to solve the signal retrieval problem if only two close fractional power spectra are known.

Energy Internet, EarlyView.ABSTRACT Accurate identification of broadband oscillation types is a prerequisite for implementing appropriate control strategies. The strongly nonlinear, nonstationary and multi‐modal characteristics of broadband oscillation signals impose higher demands on identification methods. Practical applications face challenges such as coupling effects between
