Advanced Science, EarlyView.Patch‐clamp experiments are fundamental to the measurement and understanding of ion currents that underlie physiological functions from neural activity to muscle contraction. Via a mathematical model of the experimental apparatus, this article highlights how artifact effects can be as large as some reported mutation and drug effects, and enables ...

On some geometric properties and Hardy class of q-Bessel functions
AIMS Mathematics, 2020 In this paper, we deal with some geometric properties including starlikeness and convexity of order α of Jackson’s second and third q-Bessel functions which are natural extensions of classical Bessel function Jν.

Secondary Electron Hyperspectral Imaging of Carbons: New Insights and Good Practice Guide
Advanced Science, EarlyView.Secondary hyperspectral imaging of carbon surfaces is assessed with reference materials and in comparison to standard spectroscopies. Characterization of functional carbon materials from battery research reveals otherwise inaccessible information about the distribution of sp2 and amorphous carbon, as shown in graphite anode and carbon coated lithium ...

Advanced Science, EarlyView.During object grasping in macaques, information flow between the primary sensory cortex (S1) and the primary motor cortex (M1) is modulated by tactile properties of the target. Intracortical micro‐stimulation in S1 reliably evokes M1 responses that resemble those naturally generated during grasping under specific tactile conditions.

IET Power Electronics, EarlyView., 2022 New modified carrier‐based level shifted pulse width modulation approaches for single‐phase trinary dc source fed cascaded H‐bridge inverters are proposed in this article. In order to suppress the lower order harmonics, the carrier frequency is often tuned higher. However, switching and electromagnetic interference problems have a significant influence

NUMERICAL CALCULATION OF BESSEL FUNCTIONS [PDF]
International Journal of Modern Physics C, 2012 A new computational procedure is offered to provide simple, accurate and flexible methods for using modern computers to give numerical evaluations of the various Bessel functions. The trapezoidal rule, applied to suitable integral representations, may become the method of choice for evaluation of the many special functions of mathematical physics.

Spin‐Orbit Angular Momentum Conversion in Coupled Nonparaxial Bessel Acoustic Vortices
Advanced Science, EarlyView.This study gives a formulaic description of the spin‐orbit angular momentum (AM) conversion in coupled fields of two nonparaxial Bessel acoustic vortices. Experimental results of wave field measurements provide compelling evidence for spin‐orbit AM conversion via passive artificial structures.

Frobenius Determinants and Bessel Functions [PDF]
, 2019 We study the geometry and partial differential equations arising from the consideration of Frobenius determinants, also called-group-determinants. This leads us to address some aspects of twistor theory as well as some extensions of Bessel functions.
