Numerically Stable form of Green’s Function for a Free-Free Uniform Timoshenko Beam

open access: yesMathematics, 2022
Beam models are widely applied in civil engineering, transport, and industry because the beams are basic structural elements. When dealing with the high-order modes of beam in the context of applying the modal analysis method, the numerical instability ...

Exponential-Distance Weights for Reducing Grid-like Artifacts in Patch-Based Medical Image Registration

open access: yesSensors, 2021
Patch-based medical image registration has been well explored in recent decades. However, the patch fusion process can generate grid-like artifacts along the edge of patches for the following two reasons: firstly, in order to ensure the same size of ...

Linkage disequilibrium and the genetic distance in livestock populations: the impact of inbreeding

open access: yesGenetics Selection Evolution, 2004
Genome-wide linkage disequilibrium (LD) is subject to intensive investigation in human and livestock populations since it can potentially reveal aspects of a population history, permit to date them and help in fine-gene mapping.

Bounds for Quotients of Inverse Trigonometric and Inverse Hyperbolic Functions

open access: yesAxioms, 2022
We establish new simple bounds for the quotients of inverse trigonometric and inverse hyperbolic functions such as sin−1xsinh−1x and tanh−1xtan−1x. The main results provide polynomial bounds using even quadratic functions and exponential bounds under the

INCOMPLETE EXPONENTIAL SUMS OVER EXPONENTIAL FUNCTIONS [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2014
We extend some methods of bounding exponential sums of the type $\displaystyle\sum_{n\le N}e^{2 iag^n/p}$ to deal with the case when $g$ is not necessarily a primitive root. We also show some recent results of Shkredov concerning additive properties of multiplicative subgroups imply new bounds for the sums under consideration.

Soil heat flux and air temperature as factors of radon (Rn-222) concentration in the near-ground air layer

open access: yesNukleonika, 2016
A unique, highly time-resolved, and synchronous three-year dataset of near-surface atmospheric radon-222 as well as soil heat flux and air temperature measurements at two sites (rural and urban) in Central Poland are investigated.

Sharp Bounds of Hankel Determinant on Logarithmic Coefficients for Functions Starlike with Exponential Function

open access: yesFractal and Fractional, 2022
Using the Lebedev–Milin inequalities, bounds on the logarithmic coefficients of an analytic function can be transferred to estimates on coefficients of the function itself and related functions.

Modeling and evaluation of lactation curve functions in Gir cattle

open access: yesIndian Journal of Animal Sciences, 2021
The aim of the study was to model and evaluate five different non-linear lactation curve functions for their efficiency of explaining the variations in first lactation milk yield of Gir cows maintained in the farmers herds.

Deformed exponentials and logarithms in generalized thermostatistics [PDF]

open access: yesPhysica A316, 323-334 (2002), 2002
Criteria are given that kappa-deformed logarithmic and exponential functions should satisfy. With a pair of such functions one can associate another function, called the deduced logarithmic function. It is shown that generalized thermostatistics can be formulated in terms of kappa-deformed exponential functions together with the associated deduced ...

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
