Determination of Dielectric Resonators Properties Using Multimode Contour Integral Method [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2011 Multimode contour integral method is one of methods in analysis and design of H-plane waveguide circuits. In this method, the effect of higher order modes excited by discontinuities in waveguide structure is considered.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Singular integral operators. The case of an unlimited contour
Journal of Numerical Analysis and Approximation Theory, 2005 Let \(\Gamma\)be a closed or unclosed unlimited contour, a shift \(\alpha(t)\) maps homeomorphicly the contour \(\Gamma\) onto itself with preserving or reversing the direction on \(\Gamma\) and also satisfies the conditions: for some natural \(n\geq2\),

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

IET Electric Power Applications, 2023 In this study, a fractional‐order integral terminal sliding mode control (FITSMC) system is proposed to control a new voice coil motor (VCM)‐driven X–Y motion stage with different thrust forces in the X–Y axes for the tracking of reference contours ...

The effect of aging on contour integration
Vision Research, 2008 Perception of global patterns requires the integration of local orientation information across space. The present study examined whether this integration ability declines in older age. We measured contrast thresholds for discriminating the global orientation of a "C" shaped contour against a blank background in younger and older subjects.

Euler Sums and Contour Integral Representations [PDF]
Experimental Mathematics, 1998 This paper develops an approach to the evaluation of Euler sums involving harmonic numbers either linearly or nonlinearly. We give explicit formul{æ} for certain classes of Euler sums in terms of values of the Riemann zeta function at positive integers. The approach is based on simple contour integral representations and residue computations.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Contour integral method for European options with jumps
, 2013 We develop an efficient method for pricing European options with jump on a single asset. Our approach is based on the combination of two powerful numerical methods, the spectral domain decomposition method and the Laplace transform method.
