A computational modelling of micro strip patch antenna and its solution by RDTM
Alexandria Engineering Journal, 2018 This paper concerns with the modelling of a micro strip antenna with strip line feeding technique formulated using Ohm’s law. A partial differential equation is obtained from the model which is solved using “Reduced Differential Transformation Method ...

IEEE Access, 2023 With the increasing speed of urban rail trains, the vibration between the pantograph collector strip and the contact wire intensifies, and the pantograph-catenary arc occurs frequently, which severely wear the surface materials of the pantograph-catenary.

Theory of nucleon-nucleon scattering in the strip approximation to the mandelstam representation [PDF]
Annals of Physics, 1963 Abstract The nucleon-nucleon scattering amplitude is discussed within the framework of the strip approximation. Asymptotic bounds to the behavior of the amplitudes are derived, and are applied to limit the number of “allowed” single spectral functions to six and correspondingly to limit the types of dynamically independent one-particle states.

Entanglement entropy at higher orders for the states of a = 3 θ = 1 Lifshitz theory
Nuclear Physics B, 2019 We evaluate the entanglement entropy of strips for boosted D3-black-branes compactified along the lightcone coordinate. The bulk theory describes 3-dimensional a=3 θ=1 Lifshitz theory on the boundary.

Weber Blockade Theory of Magnetoresistance Oscillations in Superconducting Strips
Physical Review Letters, 2011 Recent experiments on the conductance of thin, narrow superconducting strips have found periodic fluctuations, as a function of the perpendicular magnetic field, with a period corresponding to approximately two flux quanta per strip area [A. Johansson et al., Phys. Rev. Lett. {\bf 95}, 116805 (2005)].

Diffraction by a rigid strip in a plate modelled by Mindlin theory [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020 We consider a plane flexural wave incident on a semi-infinite rigid strip in a Mindlin plate. The boundary conditions on the strip lead to three Wiener–Hopf equations, one of which decouples, leaving a scalar problem and a 2 × 2 matrix problem. The latter is solved using a simple method based on quadrature.

Journal of the Mechanical Behavior of Materials, 2012 A finite element analysis indicates a good correlation between the Dugdale plastic strip model and a linear elastic/perfectly plastic material under plane stress loading conditions for a flow theory of plasticity based on the Tresca yield condition.

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.

Comparison between Keller's and Ufimtsev's theories for the strip [PDF]
IEEE Transactions on Antennas and Propagation, 1971 The high-frequency backscattered far field produced by a plane electromagnetic wave obliquely incident on a perfectly conducting infinite strip is considered. A comparison is made between the results obtained by applying Keller's and Ufimtsev's asymptotic theories. It is shown that Ufimtsev's expansion is incorrect beyond the leading term, but that the

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
