Let $\xi $ denote space–time white noise, and consider the following stochastic partial differential equations on $\mathbb{R}_{+}\times \mathbb{R}$: (i) $\dot{u}=\frac{1}{2}u"+u\xi $, started identically at one; (ii) $\dot{Z}=\frac{1}{2}Z"+\xi zero. It is well known that solution to intermittent, whereas not. And two are be in different universality classes. We prove tall peaks of both systems multifractals a natural large-scale sense. Some this work extended also establish multifractal...
Magnetic flux leakage (MFL) detection is frequently used for oil and gas pipeline inspection, especially evaluation of the integrity pipelines. The success MFL technique depends on many parameters. However, a sensitive magnetic sensor an important requirement. Therefore, field sensors based different mechanisms have been developed applied to technique.

Ces résultats étendent le Mueller stochastique et permettent considérer données initiales plus générales telles que mesures Dirac queue lourde qu'une croissance exponentielle linéaire en ${\pm}\infty$. généralisent travail...
We have investigated the sensitivity of a planar Hall resistance sensor as function ring radius in trilayer structure Ta(3)/IrMn(10)/Cu(0.2)/NiFe(10)/Ta(3) (nm). The diagonal components magnetoresistivity tensor rectangular prism corresponding to anisotropic magnetoresistance are few ten times larger than that off-diagonal component resistance. However, it is noteworthy resultant contribution governed by due cancellation self-balanced bridge configuration. Both experimental and theoretical...
Manipulating and separating single label-free cells without biomarker conjugation have attracted significant interest in the field of single-cell research, but digital circuitry control multiplexed individual storage remain a challenge. Herein, by analogy with electrical elements electronical holes, we develop pseudo-diamagnetophoresis (PsD) mattertronic approach presence biocompatible ferrofluids for programmable manipulation local PsD holes cells. The conduct along linear negative...
Consider the semilinear heat equation $\partial _t u = \partial ^2_x + \lambda \sigma (u)\xi$ on interval $[0 ,L]$ with Dirichlet zero-boundary condition and a nice non-random initial function, where forcing $\xi$ is space-time white noise $\lambda >0$ denotes level of noise. We show that, when solution intermittent [that is, $\inf _z|\sigma (z)/z|>0$], expected $L^2$-energy grows at least as $\exp \{c\lambda ^2\}$ most ^4\}$ \to \infty$. In case that boundary replaced by Neumann condition,...
The field sensitivity of a planar Hall effect (PHE) micro-ring type biosensor has been investigated as function magnetizing angle the sensor material, for sensing low magnetic moment superparamagnetic labels. is maximal at α = 20°. At this optimized angle, PHE about 3.6 times higher than that measured conventional configuration, 90°. This optimization enables PHE-ring to detect biolabels with ultra-low moments down 4 × 10−13 emu.
A novel method based on remotely controlled magnetic forces of bio-functionalized superparamagnetic colloids using micromagnet arrays was devised to measure frictional force at the sub-picoNewton (pN) scale for bio-nano-/micro-electromechanical system (bio-NEMS/MEMS) interfaces in liquid.
Consider the stochastic heat equation $\partial_tu=\mathscr{L}u+\lambda\sigma(u)\xi$, where $\mathscr{L}$ denotes generator of a L\'{e}vy process on locally compact Hausdorff Abelian group $G$, $\sigma:\mathbf{R}\to\mathbf{R}$ is Lipschitz continuous, $\lambda\gg1$ large parameter, and $\xi$ space-time white noise $\mathbf{R}_+\times G$. The main result this paper contains near-dichotomy for (expected squared) energy $\mathrm{E}(\|u_t\|_{L^2(G)}^2)$ solution. Roughly speaking, that dichotomy...
Abstract A promising and original method to study the spin‐transition in bistable spin‐crossover (SCO) materials using a magnetoresistive multiring sensor its self‐generated magnetic field is reported. Qualitative quantitative studies are carried out combining theoretical experimental approaches. The results show that only small part of matter dropped on surface probed by device. At low bias‐current range, number detected nanoparticles depends amplitude current. However, agreement with...
