Low frequency fluctuation of brain spontaneous activity and obsessive compulsive symptoms in a large school-age sample
(Pergamon-Elsevier Science Ltd, 2018)
Background: The present study was designed to explore alterations in brain dynamics at rest that are associated with Obsessive Compulsive Symptoms (OCS) in childhood by measuring low frequency fluctuation of spontaneous ...
Touch static analysis and dynamic exercises of insulated patients

Emergence of very long time fluctuations and 1/f noise in ideal flows
(American Physical Society, 2011-06)
This paper shows the connection between three previously observed but seemingly unrelated phenomena in hydrodynamic (HD) and magnetohydrodynamic (MHD) turbulent flows, involving the emergence of fluctuations occurring on ...
Compensation of laser frequency fluctuations and phase noise in 16-QAM coherent receivers
(Institute of Electrical and Electronics Engineers, 2013-01-18)
Frequency fluctuations caused by mechanical vibrations, power supply noise, and other mechanisms are detrimental to the phase estimator performance in high speed intradyne coherent optical receivers. In this letter, we ...
Cross-frequency coupling and phase synchronization in nonlinear acoustics
(Acoustical Society of America, 2016-09-15)
The Cross-Frequency Coupling (CFC) characterizes the correlation between the phase/amplitude of a low-frequency band with those of a high-frequency band within or across time series. The CFC phenomenon has been observed ...
New insights into the biennial-to-multidecadal variability of the water level fluctuation in Lake Titicaca in the 20th century
(Frontiers Media, 2024-01-12)
The water disponibility of Lake Titicaca is important for local ecosystems, domestic water, industry, fishing, agriculture, and tourism in Peru and Bolivia. However, the water level variability in Lake Titicaca (LTWL) still ...
Electrostatically actuated encased cantilevers
(Beilstein-Institut züur Forderung der Chemischen Wissenschaften, 2018-05)
Background: Encased cantilevers are novel force sensors that overcome major limitations of liquid scanning probe microscopy. By trapping air inside an encasement around the cantilever, they provide low damping and maintain ...
Fluctuations in range and abundance of snow crab (Chionoecetes opilio) from the eastern Bering Sea: What role for Pacific cod (Gadus macrocephalus) predation?
(University of Miami. Rosenstiel School of Marine and Atmospheric Science, 2013-01)
Fluctuations in abundance of commercially valuable crustacean stocks in sub-Arctic ecosystems have been variously attributed to the effects of climatic forcing, fishing pressure, and predation, mostly by gadoid fishes. ...
Cage effect in Poly(alkyl methacrylate) thin films studied by nile red single molecule fluorescence spectroscopy
(American Chemical Society, 2012-03)
Interactions in a probe–polymer cage were monitored by spectral fluctuations in the emission spectroscopy of single molecules of Nile Red in poly(alkyl methacrylate) thin films (25–200 nm) in the 278–323 K temperature ...
Efficient Parallel Carrier Recovery for Ultrahigh Speed Coherent QAM Receivers with Application to Optical Channels
(Hindawi Publishing Corporation, 2013-03)
This work presents a new efficient parallel carrier recovery architecture suitable for ultrahigh speed intradyne coherent optical receivers (e.g., ≥100 Gb/s) with quadrature amplitude modulation (QAM). The proposed scheme ...
