A Refinement of Backward Correlation Technique for Precise Brillouin Frequency Shift Extraction

open access: yesFibers, 2023
A new method for extracting the Brillouin frequency shift (BFS) from the Brillouin gain spectrum (BGS), the modified backward correlation method (MBWC), is presented.

A Novel Viewpoint on the Anticipatory Postural Adjustments During Gait Initiation

open access: yesFrontiers in Human Neuroscience, 2021
Anticipatory postural adjustments (APAs) are the coordinated muscular activities that precede the voluntary movements to counteract the associated postural perturbations. Many studies about gait initiation call APAs those activities that precede the heel-

The concepts of Lie derivative for discrete-time systems; pp. 253–265 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2012
The paper extends the concept of the Lie derivative of the vector field, used in the study of the continuous-time dynamical systems, for the discrete-time case.

Backward THz Emission from Two-Color Laser Field-Induced Air Plasma Filament

open access: yesSensors, 2023
Two-color laser field-induced plasma filaments are efficient broadband terahertz (THz) sources with intense THz waves emitted mainly in the forward direction, and they have been investigated intensively.

Nabla derivatives associated with nonlinear control systems on homogeneous time scales

open access: yesNonlinear Analysis, 2016
The backward shift and nabla derivative operators, defined by the control system on homogeneous time scale, in vector spaces of one-forms and vector fields are introduced and some of their properties are proven.

Dynamic Programming Analysis for Measuring the Optimization of the Manpower per Shift PT. XYZ

open access: yesJurnal Serambi Engineering, 2021
The problems that occur in the company is the production system make to order, for example PT. XYZ. Unknown certainty the amount of the order lenses will be produced. So it is not known how labor should be allocated to each shift.

Non-goal driven eye movement after a visual search task

open access: yesJournal of Eye Movement Research, 2022
We investigated the functions and mechanisms of non-goal-driven eye movements, which are defined as eye movements induced when looking at visual stimuli on a display without engaging in a specific task or looking at a display without any visual ...

Adaptation of the Compensatory Stepping Response Following Predictable and Unpredictable Perturbation Training

open access: yesFrontiers in Human Neuroscience, 2021
BackgroundEffective training of the backward step response could be beneficial to improve postural stability and prevent falls. Unpredicted perturbation-based balance training (PBT), widely known as compensatory-step training, may enhance the fear of ...

Asymptotic Behaviour and Cyclic Properties of Weighted Shifts on Directed Trees [PDF]

open access: yes, 2016
In this paper we investigate a new class of operators called weighted shifts on directed trees introduced recently in [Z. J. Jablonski, I. B. Jung and J. Stochel, A Non-hyponormal Operator Generating Stieltjes Moment Sequences, J. Funct. Anal. 262 (2012),

QED Radiative Corrections to $Z$ Boson Production and the Forward Backward Asymmetry at Hadron Colliders [PDF]

open access: yes, 1997
The ${\cal O}(\alpha)$ radiative corrections to the process $p\,p\hskip-7pt\hbox{$^{^{(\!-\!)}}$} \rightarrow \gamma^*, \, Z \rightarrow \ell^+ \ell^-$ ($\ell=e,\,\mu$) are calculated.
