A magnetohydrodynamic numerical model for hydrogenic pellet ablation in the electrostatic approximation has been developed based on method of front tracking. The main features are explicit tracking interfaces that separate solid from ablated gas and cold, dense weakly ionized cloud highly conducting fusion plasma, a surface model, kinetic electron heat flux an equation state accounting atomic processes cloud. interaction flow with magnetic field including J × B Lorentz force is studied here...
Motivated by the production of strong optical forces on atoms, we have done numerical studies adiabatic rapid passage in light that is both frequency and amplitude modulated form chirped pulses, found unanticipated regularities. We quantified these regularities terms a periodic Hamiltonian, obtained result similar to Bloch theorem, but time domain. This led further quantitative description behavior an atom under multiply repetitive sweeps.
Introduction: Accumulating evidence indicates that ferroptosis, an iron-dependent cell death, is involved in the development of tumors, and targeting ferroptosis offers great potential tumor therapy. However, regulatory networks peripheral T lymphoma (PTCL) remain unclear. Methods: Paraffin-embedded tissues 112 PTCL patients 38 reactive hyperplasia cases were collected with informed consents. Lentiviral vectors stably transfected into lines. Tandem mass tag (TMT)-mass spectrometry...
We study Rayleigh–Taylor instability in both the moderately compressible and weakly regimes. For two-dimensional single mode case, we find that dimensionless terminal velocities (and associated Froude numbers) are nearly constant over most of this region parameter space, as thermodynamic parameters describing equation state varied. The phenomenological drag coefficient which occurs buoyancy-drag is directly related to has a similar behavior. Pressure differences interface shape, however,...

To apply the adiabatic rapid passage process repetitively [T. Lu, X. Miao, and H. Metcalf, Phys. Rev. A 71, 061405(R) (2005)], nonadiabatic transition probability of a two-level atom subject to chirped light pulses over finite period time needs be calculated. Using unitary first-order perturbation method in rotating frame, an approximate formula has been derived for such probabilities entire parameter space pulses.
Large-scale diffraction gratings, ranging from sub-meter to meter in size, play a vital role spectrometers and various measurement technologies. The primary method for fabricating these gratings is holographic exposure, which requires large-aperture laser beams low-aberration wavefronts, limiting the size of that can be fabricated single exposure. To expand grating we employ mosaic exposure method, where different areas substrate are sequentially exposed by repositioning beams. This...
When using a combination of contact lithography and laser interferometric for multi-exposure in separate areas, alignment errors between the mask substrate can lead to splicing photoresist pattern. This seriously affect quality patterns. In this paper, we propose profile-based method mitigate effect error by calibrating relative displacement plate substrate. We design brightfield that includes one central processing area four scale mark areas. The areas consist alternating normal serrated...

Contrast sensitivity is an important feature of functional vision, but traditional psychometric assessment methods require too many trials to estimate a complete contrast function across the full range spatial frequencies relevant normal vision in humans. To overcome this challenge, Quick CSF (qCSF), Bayesian adaptive procedure observer's (Lesmes, Lu, Baek, & Albright, 2010), assumes four-parameter model (Watson Ahumada, 2005). The parametric nature allows for more rapid evaluation through...
Abstract In this paper, we study the superconvergence of semi-discrete discontinuous Galerkin (DG) method for linear hyperbolic equations in one spatial dimension. The asymptotic errors cell averages, downwind point values, and postprocessed solution are derived initial discretization by Gaussian projection (for periodic boundary condition) or Cao et al.
