An optimization method for designing high rate and high performance SCTCM systems with in-line interleavers

We present a method for designing high-rate, high-performance SCTCM systems with in-line interleavers. Using in-line EXIT charts and ML performance analysis, we develop criteria for choosing constituent codes and optimization methods for selecting the best ones. To illustrate our methods, we show that an optimized SCTCM system with an in-line interleaver for rate r = 5/6 and 64QAM has better performance than other turbo-like TCMs with the same parameters

A new perfusion culture method with a self-organized capillary network

A lack of perfusion has been one of the most significant obstacles for three-dimensional culture systems of organoids and embryonic tissues. Here, we developed a simple and reliable method to implement a perfusable capillary network in vitro. The method employed the self-organization of endothelial cells to generate a capillary network and a static pressure difference for culture medium circulation, which can be easily introduced to standard biological laboratories and enables long-term cultivation of vascular structures. Using this culture system, we perfused the lumen of the self-organized capillary network and observed a flow-induced vascular remodeling process, cell shape changes, and collective cell migration. We also observed an increase in cell proliferation around the self-organized vasculature induced by flow, indicating functional perfusion of the culture medium. We also reconstructed extravasation of tumor and inflammatory cells, and circulation inside spheroids including endothelial cells and human lung fibroblasts. In conclusion, this system is a promising tool to elucidate the mechanisms of various biological processes related to vascular flow

Properties of hadron screening masses at small baryonic density

The properties of hadron screening masses around the deconfinement phase transition at finite baryonic density can be studied by evaluating the Taylor coefficients with respect to the iso-scalar and iso-vector chemical potentials. We simulate 2-flavour lattice QCD with staggered fermions on a 12*12*24*6 lattice with ma = 0.05 and 0.10 and report investigations of nucleon, pseudo-scalar and vector mesons. We present new, strong evidence that in the confining phase, the screening masses at vanishing chemical potential have significant temperature dependence, but the effect of the iso-scalar chemical potential is very small. Above the critical temperature, the second derivative terms of mesons rapidly increase as contrasted to the case of baryon. We also study the responses of the screening masses to an iso-vector chemical potential and discuss some of the issues related to the properties of hadron masses at finite density.Comment: 7 pages with 5 figures; added two new references, the title of article and the section 'Concluding Remarks' are slightly change

Convergence analysis of SCCC and SCTCM with 'in-line' interleaver

This paper presents a technique for analyzing the performance of SCCC and SCTCM systems that use 'in-line' interleavers. This technique is a multidimensional extension of the well-known EXIT chart analysis, and enables us to optimize the constituent codes when in-line interleavers are used

A CLINICO-PATHOLOGICAL SURVEY OF EXOPHYTIC TUMORS OF THE URINARY BLADDER I. An Analysis of the Structure of the Fibro-vascular Cores With Special References to the Clinical Prognosis

In this paper the results of the clinicopathological study on a total of 79 bladder tumor cases are presented. They are principally related to the stromal proliferation or branching of the tumors. The tumor cases consist of those with a good prognosis as well as those with a poor prognosis. In the former category there are 61 cases with a long survival history (with or without recurrence); the remainder (18 cases) had a history of a short survival (dying within 2 years). Histologically there was a marked difference in the regularity of the stromal branching of the tumor between those cases with a long survival history and those cases with a short survival history. In the former group the regular type of stromal branching was predominant; in the latter group the irregular type was predominant
