Pelvic floor contraction as an initial response to psycho-sensory sexual stimulation in men and a trigger for male sexual behaviour.

Introduction: This study is based on the hypothesis that, in men, the initial sexual response to erotic stimuli is triggered by a psycho-sensory pelvic reflex, mediated by the contraction of the pelvic floor muscles (PFM), rather than by an erection.

Objective: The objective is to determine, using a questionnaire that evokes an erotic image, whether there is a correlation between an erotic psycho-sensory stimulus and PFM contraction in men and females and whether this contraction encourages the subject to seek sexual activity.

Materials And Methods: An online questionnaire was administered to 270 respondents (134 males, 136 females; mean age = 36.

Electrospun Poly(vinylidene fluoride) Nanocomposites with Ionic Liquid Functionalized Graphene Nanoplatelets by a Noncovalent Method for Piezoresistive Pressure Sensor Applications.

Piezoresistive pressure sensors have been prepared by the electrospinning of poly(vinylidene fluoride) (PVDF) containing graphene nanoplatelets (GNP) functionalized using 1-butyl-3-methylimidazolium trifluoromethanesulfonate (BMIM(OTf)) ionic liquid (IL). Optical microscopy demonstrated that the functionalized GNP powder presented particles with a smaller lateral size. The obtained mats were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, differential scanning calorimetry, electrical resistivity using two and four probes, and electromechanical testing with up to 32 load-unload cycles.

In their narratives: academic socialization in the experience of sensory processing sensitivity among university students.

Introduction: While much of the worldwide contemporary research on sensory processing sensitivity (SPS) and environmental sensitivity (ES) has relied on the participation of university students, there remains a significant gap in understanding the academic social experiences of those scoring high in SPS (i.e., highly sensitive individuals).

In situ observations of large-amplitude Alfvén waves heating and accelerating the solar wind.

After leaving the Sun's corona, the solar wind continues to accelerate and cools, but more slowly than expected for a freely expanding adiabatic gas. Alfvén waves are perturbations of the interplanetary magnetic field that transport energy. We use in situ measurements from the Parker Solar Probe and Solar Orbiter spacecraft to investigate a stream of solar wind as it traverses the inner heliosphere.

Multi-source connectivity as the driver of solar wind variability in the heliosphere.

The ambient solar wind that fills the heliosphere originates from multiple sources in the solar corona and is highly structured. It is often described as high-speed, relatively homogeneous, plasma streams from coronal holes and slow-speed, highly variable, streams whose source regions are under debate. A key goal of ESA/NASA's Solar Orbiter mission is to identify solar wind sources and understand what drives the complexity seen in the heliosphere.
