Multi-photon fluorescence microscopy (MFM) captures high-resolution anatomical and functional fluorescence image sequences and can be used for the intact brain imaging of small animals. Recently, it has been extended from imaging anesthetized and head-stabilized animals to awake and head-restrained ones for in vivo neurological study. In these applications, motion correction is an important pre...

Magnetic micro-structural uniformity of die-upset Nd-Fe-B magnets" (2012). Si-Hwang Liou Publications. Paper 101. magnets have been prepared with height reduction (h) in the range of 60 to 88%. The energy product as high as 50.4 MGOe was obtained in the sample with h $ 70%. The magnetic domains of the samples are revealed by using magnetic force microscopy (MFM). The average domain widths of th...

Surrogate models of fitness have been presented as a way of reducing the number of fitness evaluations required by evolutionary algorithms. This is of particular interest with expensive fitness functions where the time taken for building the model is outweighed by the saving of using fewer function evaluations. In this paper, we show how a Markov network model can be used as a surrogate fitness...

Membrane capacitance and membrane conductance values are reported for insulin secreting cells (primary -cells and INS-1 insulinoma cells), determined using the methods of dielectrophoresis and electrorotation. The membrane capacitance value of 12.57 (+/-1.46) mFm(-2), obtained for -cells, and the values from 9.96 (+/-1.89) mFm(-2) to 10.65 (+/-2.1) mFm(-2), obtained for INS-1 cells, fall within...

Despite decades of advances in magnetic imaging, obtaining direct, quantitative information with nanometer scale spatial resolution remains an outstanding challenge. Current approaches, for example, Hall micromagnetometer and nitrogen-vacancy magnetometer, are limited by highly complex experimental apparatus and a dedicated sample preparation process. Here we present a new AC field-modulated ma...

The evolution of the Kelvin-Helmholtz Instability (KHI) is widely used to assess performance numerical methods. We employ this instability test both smoothed particle hydrodynamics (SPH) and meshless finite mass (MFM) implementation in OpenGadget3. quantify accuracy SPH MFM reproducing linear growth KHI with different physical set-ups. Among them, we consider: $i)$ induced viscosity, $ii)$ phys...

Emergencies, especially major ones, happen fast, randomly, as well as unpredictably, and generally will bring great harm to people's life and the economy. Therefore, governments and lots of professionals devote themselves to taking effective measures and providing optimal evacuation plans. This paper establishes two different emergency evacuation models on the basis of the maximum flow model (M...

The author have developed a new SCC test method that enables the super Kelvin force microscope (SKFM) and the Kelvin force microscope (KFM) observations. By using this test device, the crack tip deformation and surface potential distribution were observed on SUS310S stainless steel by SKFM and KFM. At the same time, the distribution of hydrogen was examined by the Ag decoration method with the ...

The stress corrosion cracking (SCC) of stainless steel is one of the biggest problems for maintaining atomic power and chemical plants. However the mechanism has not been solved because of difficulty in observing hydrogen movement. In order to solve this problem, the author has developed a new SCC test method that enables the super Kelvin force microscope (SKFM) and the Kelvin force microscope ...

The authors describe and compare two complementary techniques that are habitually used to image ferromagnetic ferroelectric materials with sub-micron spatial resolutions (typically 50 nm, at best 10 nm). first technique is variable-temperature photoemission electron microscopy magnetic/antiferromagnetic/polar contrast from circularly/linearly polarized incident X-rays (XPEEM). second magnetic f...
