Lock-in of the vortex-induced vibrations of a long tensioned beam in shear flow [PDF]
, 2011 The occurrence of lock-in, defined as the local synchronization between the vortex shedding frequency and the cross-flow structural vibration frequency, is investigated in the case of a tensioned beam of length to diameter ratio 200, free to move in both

Breaking Out of Carbon Lock-In: Malaysia’s Path to Decarbonization
Frontiers in Built Environment, 2020 Malaysia has made an ambitious commitment to reduce the intensity of its carbon emissions, notably a 40% reduction (compared to 2005 levels) by 2020 and a 45% reduction (compared to 2005 levels) by 2030.

Lock-in detection for pulsed electrically detected magnetic resonance [PDF]
, 2011 We show that in pulsed electrically detected magnetic resonance (pEDMR) signal modulation in combination with a lock-in detection scheme can reduce the low-frequency noise level by one order of magnitude and in addition removes the microwave-induced non ...

Therapeutic Advances in Neurological Disorders, 2023 The locked-in syndrome (LiS) is characterized by quadriplegia with preserved vertical eye and eyelid movements and retained cognitive abilities. Subcategorization, aetiologies and the anatomical foundation of LiS are discussed. The damage of different structures in the pons, mesencephalon and thalamus are attributed to symptoms of classical, complete ...

Short-Term Magnetic Field Variations From the Post-depositional Remanence of Lake Sediments
Frontiers in Earth Science, 2018 Paleomagnetic records obtained from lake sediments provide important constraints on geomagnetic field behavior. Secular variation recorded in sediments is used in global geomagnetic field models, particularly over longer timescales when archeomagnetic ...
