Solving linear equations is one of the fundamental problems in numerical calculation and has a wide application in many science and engineering fields. We present a family of P systems to solve linear equations in which the coefficients are real numbers. An instance is given to illustrate the feasibility and effectiveness of our designed P systems. Our work contributes to make P systems to solve more complicated computation problems effectively.

The satisfiability problem(SAT) is a well known NP-complete problem. Obtaining All of the truth assignments of SAT is called All-SAT and it has numerous applications in artificial intelligence and computer theories. Many algorithms about SAT have been built, but how to solve All-SAT is still difficult. P system is a new distributed and parallel computation model. We use membrane division, which is frequently investigated to obtain an exponential working space in a linear time, to design a family of P systems to solve All-SAT in polynomial *** work provides a new and effective solution to All-SAT in a distributed and parallel manner.

Boolean and relational operations, which are defined for solving mathematically logical problems,are always required in computing models. Membrane computing is a kind of distributed parallel computing *** this paper, we design different membranes for implementing primary Boolean and relational operations respectively. And based on these membranes, a membrane system can be constructed by a present algorithm for evaluating a logical expression. Some examples are given to illustrate how to perform the Boolean, relational operations and evaluate the logical expression correctly in these membrane systems.

现毕节市大方县六龙豆干制作坊炉灶大多为传统的单灶或双灶并立靠墙排放,这种传统炉灶在煤炭燃烧过程中有部分热量随着实心炉壁吸热再散热流失,部分热量随着炉灶烟道废气排放流失,致使煤炭燃烧有效利用率仅仅达到60%左右。为热量回收利用,对炉灶结构进行改良,设计出一种绿色、健康、多功能的豆干制作炉灶。炉灶为豆干作坊提供三个区域的烘干功能和一个暖水箱功能,能根据豆干不同的湿度选择相应温度的烘干区域。此外,还能为工作人员长期提供温水,降低了豆干制品的制造成本。

弥漫大B细胞淋巴瘤(DLBCL)是一类异质性较高的恶性肿瘤。目前,多种指标被用于预测DLBCL的预后。然而,近年来不断涌现的新药及新型治疗手段使得现有的风险预测模型预后价值有限,无法精确指导治疗。随着高通量技术的飞速发展,有关DLBCL分子生物学的研究取得了很大的进步。各种新型生物标志物的出现为深入了解该疾病的发生发展机制、治疗优化及预后评估提供了重要依据。文章对近年来DLBCL预后相关分子标志物进行综述,主要涵盖血清及血浆、分子遗传学、肿瘤微环境等方面,旨在为DLBCL的精准治疗提供一定的理论依据。
