Oscillations During Flow Boiling in Single Microchannels
Acta Chimica Slovenica, 2018 Flow boiling of degassed double-distilled water in a single 50 × 50 μm and 100 × 50 μm microchannel was investigated on the basis of experimental measurements and high-speed visualization.

Cortical circuit activity underlying sleep slow oscillations and spindles
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Slow oscillations and spindles are hallmarks of the EEG during slow-wave sleep. They are thought to support memory consolidation, particularly in instances where the faster spindle nests into the “upstate” of a slow oscillation.

Investigation of quasi-periodic varaiations in hard X-rays of solar flares
, 2009 The aim of the present paper is to use quasi-periodic oscillations in hard X-rays (HXRs) of solar flares as a diagnostic tool for investigation of impulsive electron acceleration.

Advanced Engineering Materials, EarlyView.A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Ubiquity of density slope oscillations in the central regions of galaxy and cluster-sized systems
, 2016 One usually thinks of a radial density profile as having a monotonically changing logarithmic slope, such as in NFW or Einasto profiles. However, in two different classes of commonly used systems, this is often not the case.

Oscillation of parabolic equations with oscillating coefficients
Hiroshima Mathematical Journal, 1994 We are concerned with the oscillatory behavior of solutions of the parabolic equation with oscillating coefficients \[ \begin{multlined} u_ t (x,t) - \left( a(t) \Delta u(x,t) + \sum^ k_{i = 1} b_ i(t) \Delta u(x,t - \sigma_ i) \right) + \\ + c \biggl( x,t, u(x,t),\;u \bigl( x, \tau_ 1(t) \bigr), \dots, u \bigl( x, \tau_ m(t) \bigr) \biggr) = f(x,t ...

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Nasal Respiration Entrains Human Limbic Oscillations and Modulates Cognitive Function
Journal of Neuroscience, 2016 The need to breathe links the mammalian olfactory system inextricably to the respiratory rhythms that draw air through the nose. In rodents and other small animals, slow oscillations of local field potential activity are driven at the rate of breathing (∼
