Abstract Background Ankylosing spondylitis (AS) is a chronic inflammatory disorder marked by spinal ossification that leads to progressive thoracolumbar kyphosis (TLK). We previously introduced vertebral body compression...

Stimulated Raman scattering (SRS) microscopy is a fast Raman imaging technique that combines the molecular specificity of vibrational spectroscopy with the high spatial resolution and speed of laser-scanning microscopy. ...

Introduction We developed an innovative, active learning workshop to introduce foundations of point-of-care ultrasound (POCUS) physics and instrumentation. The workshop design aimed to reduce cognitive load and encourage...

INFN-CHNet is the cultural heritage network of the Italian National Institute of Nuclear Physics (INFN) and is constituted by units from Italy and from outside Europe, one of them at Universidad Nacional de San Martín (...

As an important part of the novel power system, the renewable energy converging and boosting power grid has the phenomenon of cross and mutual supply, which leads to the inaccurate calculation of the existing line loss. ...

With the proposal of the national dual-carbon strategic goal, distributed photovoltaic (PV) ushers in new development opportunities, and the management of voltage quality for photovoltaic power stations becomes a key cha...

With the rapid escalation of carbon dioxide emissions, the contradiction between economy, environment and energy is becoming more and more prominent, and the power generation industry, as a typical carbon emission subjec...

Aiming at the problem that the topology of low-voltage distribution network is complex and leads to low fault segment localization accuracy, a fault segment localization method based on voltage difference network mapping...

In response to the unstable accuracy rate of fault location in distribution network lines and the significant impact of communication with distribution automation devices, the fault perception analysis of distribution ne...

The occurrence of tree-contact single-phase-to-ground fault (TSF) poses a potential threat to the stable operation of power lines, and in severe cases, may result in wild fire. The development of TSF is influenced by cru...

As the core component of the electromagnetic force compensation weight detector, the force measurement sensitivity of the integrated flexible hinge sensor directly determines the resolution of the electromagnetic force c...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

Aiming at the problem of power quality disturbance (PQD) classification, classification sub-models based on one-dimension CNN in the time domain (original signal), frequency domain (Fourier transform) and time-frequency ...

Direct-drive wind farms usually trip all wind turbines to ensure power grid security when facing sub/super-synchronous oscillation risks. Tripping the entire wind farm not only seriously damages the production operation ...
