• Lambert-W function-based MOSFET parameter extraction down to cryogenic temperature. modeling of drain current characteristics using classical mobility law 4.2 K. Main FDSOI parameters extracted versus temperature and gate length. Mobility degradation at short channel length due increased neutral defect scattering. The applicability the methodology is demonstrated for 28 nm MOSFETs deep temper...

A simple mathematical model for the temperature evolution in cornea exposed to short-pulsed Ho: YAG laser under Laser Thermo Keratoplasty (LTK) treatment is developed by incorporating heat flux phase-lag Fourier’s transfer and source term described Lambert Beer’s law. An analytical solution obtained using Laplace transformation technique. The computational results profile variation with time ar...

A new chaotic circuit is practically realized, for the first time, using a Lambert W-function. The circuit consists of three main parts. The first part employs a well-known Wilson current mirror, whereas the second part is a simple resistor at the two connected emitters of the current mirror. Both parts form a new circuit for a Lambert W-function by enabling a term of an emitter current to be s...

We quantified stand leaf area index and vertical leaf area distribution, and developed canopy extinction coefficients (k), in four mature hardwood stands. Leaf area index, calculated from litter fall and specific leaf area (cm*.g-‘), ranged from 4.3 to 5.4 m*.rn-r. In three of the four stands, leaf area was distributed in the upper canopy. In the other stand, leaf area was uniformly distributed...

Photoplethysmography (PPG) is a technique that uses light to noninvasively obtain a volumetric measurement of an organ with each cardiac cycle. A PPG-based system emits monochromatic light through the skin and measures the fraction of the light power which is transmitted through a vascular tissue and detected by a photodetector. Part of thereby transmitted light power is modulated by the vascul...

We show how Rank-Crank type PDEs for higher order Appell functions due to Zwegers may be obtained from a generalized Lambert series identity due to the first author. Special cases are the Rank-Crank PDE due to Atkin and the third author and a PDE for a level 5 Appell function also found by the third author. These two special PDEs are related to generalized Lambert series identities due to Watso...
