Why Current Publication Practices May Distort Science
PLoS Medicine, 2008 John Ioannidis and colleagues argue that the current system of publication in biomedical research provides a distorted view of the reality of scientific data.

Distorted Modeling of Density Currents
Coastal Engineering 1972, 1972 The paper describes a method of choosing scales for the correct representation of convective spread in a hydraulic model involving densimetric phenomena. Although most prototype spreads are non-viscous in nature it is possible for small scale laboratory spreads to become affected by viscous influence when the spreading density front is remote from the ...

Persistent currents in distorted quantum ring
Journal of Physics: Conference Series, 2008 Persistent currents in distorted narrow mesoscopic rings threaded by the magnetic flux of the Aharonow Bohm type are investigated. It is shown that the ring distortions can be modelled by an appropriate potential term. The cases with a single and multiple distortions are considered. The single distortion opens a gap in the electron energy spectrum of a

Sensors, 2021 Conventional current transformers (CTs) suffer from nonlinearities due to their ferromagnetic cores. On one hand, it is well-known that severe core saturation may occur because of large overcurrents or unidirectional transient components: this may ...

Calibration of Current Transformers in distorted conditions
Journal of Physics: Conference Series, 2018 In the context of modern power systems, where there are lots of non-linear loads and generators based on switching power electronics, the accurate measurement of voltage and current harmonics is a key task for the knowledge of the actual state of the network.

Current PTSD symptomatology distorts memory for past symptoms [PDF]
Psychiatry Research, 2019 Clinicians often rely on clients' retrospective reports of past symptoms to diagnose and treat Posttraumatic Stress Disorder (PTSD). However, there is limited research investigating memory for past PTSD symptoms. We asked sexual assault survivors to report their PTSD symptoms and then recall them 6 months later.
