We present 350 μm polarization observations of four low-mass cores containing Class 0 protostars: L483, L1157, L1448-IRS2, and Serp-FIR1. This is the second paper in a larger survey aimed at testing magnetically regulated models for core-collapse. One key prediction of these models is that the mean magnetic field in a core should be aligned with the symmetry axis (minor axis) of the flattened Y...
Abstract The scale-free ferroelectric polarization of fluorite M O 2 ( = Hf, Zr) due to flat polar phonon bands are promising for nonvolatile memories. Defects also widely introduced improve the emergent ferroelectricity. However, their roles still not fully understood at atomic-level. Here, we report a significant effect point-defect-driven flattening with more modes and contribution in doped ...
The CD++ toolkit was developed to implement the theoretical concepts specified by the DEVS formalism. CD++ has been recently enhanced to support real-time simulation, where events have to be processed in a timely manner. A synthetic benchmarking tool is used to test several models with different workloads, complexities, structures and sizes. Additionally, experiments were carried out under diff...
One of the most ubiquitous examples of origami is the common paper shopping bag. In a common model of paper folding, there are a finite number of creases, between which the paper must stay rigid and flat, as if made of plastic or metal plates connected by hinges. We show that (maybe surprisingly), the paper shopping bag cannot be flattened under this model using the usual pattern of creases. Th...
In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, three-dimensional hybrid guided modes can be calculated by us...
Golgi apparatus were released without fixatives from rat hepatocytes by gentle homogenization, concentrated by differential centrifugation, and purified by sucrose gradient centrifugation. Examination of sections of purified fractions by electron microscopy showed fields of morphologically intact units of Golgi apparatus consisting of stacks of parallel flattened cisternae, secretory vesicles, ...
This article concerns the spectral analysis of vowels sustained by hoarse and healthy speakers. Conventional cues of noise in spectral data are founded on the segregation of hannonics and interharmonics. What we propose here is an alternative that consists of flattening the spectral contour and performing a multivariate statistical analysis of the residual ( i.e. flattened ) spectral components...
