The authors propose a two-stage method for recognizing driving situations on the basis of driving signals for application to a safe human interface of an in-vehicle information system. In first stage, an unknown driving situation is determined as stopping behavior or non-stopping behavior. In second stage, a Hidden Markov Model （HMM）-based pattern recognition method is used to model and recognize six non-stopping driving situations. The authors attempt to find the optimal HMM configuration to improve the performance of driving situation recognition. Center for Integrated Acoustic Information Research （CLAIR） in-vehicle corpus is used to evaluate the HMM-based recognition method. Driving situation categories are recognized using five driving signals. The proposed method achieves a relative error reduction rate of 30.9% compared to a conventional one-stage based HMMs.

Nowadays many devices that make up a computer network are being equipped with security hardware and software features to prevent cyber security attacks. The idea is to distribute security features to intermediate systems in the network to mitigate the overall adverse effect of cyber attacks. In this paper, we will be focusing on the Juniper J4350 router with the Junos Software Enhanced, and it has security-attack protections in the router. We are going to evaluate how the Juniper router with built-in security protections affected the overall server performance under a cyber security attack.

造血干细胞(hematopoietic stem cell,HSC)一直被认为处于造血级联的顶端,通过维持自身的自我更新并逐级向下分化成熟,为机体源源不断地提供各种成熟的血细胞。基于HSC移植后分化成熟的变化规律为主要技术方法的研究表明,HSC维持着整个造血系统的稳定,并且在分化发育过程中存在多种不同的模型。然而,从根本上来讲这些研究结果反映的是HSC应对外界压力的应激反应,与正常稳态情况下HSC对于整个造血系统的维持作用并不相同。而最新的一系列利用不同的实验模型对造血祖细胞(hematopoietic progenitor cell,HPC)在造血稳态维持中的作用进行了研究,发现HPC才是造血稳态维持的"主力军"。本文将对目前存在争议的关于HSC和HPC在稳态造血系统维持中作用的最新研究进展作一评述。

造血干细胞(HSC)是发现最早、在临床中广泛应用并一直发挥范式作用的一类重要的成体组织干细胞.HSC是一个由不同功能亚群组成的高度异质性群体,其自我更新和多向分化潜能主要通过HSC移植这一"金标准"的实验流程来评估和判断.细胞群体水平的研究无法深入探讨其生物学功能,从而使HSC单细胞水平的研究成为必需.为了更好地研究HSC的异质性,本文将详细介绍HSC单细胞移植实验流程及结果检测和分析,旨在促进相关科研人员对于单细胞移植适用性的了解以及具体实验操作的掌握,客观评判具有高度异质性干细胞群体功能,为其他具有高度异质性的干细胞群体的功能研究和评价提供例举和参考.

The basic aim of this work was investigation of the contents of natural radionuclides in the samples of coal and in the products of its burning in Tuzla coal power plants (CPP), as the beginning steps to estimate total radioactive effects on the surrounding, having in mind that coal power plants are one of the more influential source of the redistribution of natural radionuclides. Coal power plants are backbone of the energy production in Bosnia and Herzegovina accounting for the 75% of the total produced energy. Gamma spectrometric analysis of samples was performed using the most modern high-resolution, low background gamma spectrometric Canberra HPGe (high purity germanium) system, with the relative efficiency of 70% at 1.33 MeV, FWHM (full width at half maximum) resolution of 2.3 keV at 1.33 MeV, 1,200 eV at 122 keV. The activity concentration of natural radionuclides in measured samples of coal, ashes and slag were from 4,4 to 56 Bq/kg for 226Ra, from 4.5 to 38 Bq/kg for 232Th, from 0.3 to 2.7 Bq/kg for 235U, from 3.1 to 57 Bq/kg for 238U and from 35 to 333 Bq/kg for 40K.

Foxtail millet （Setaria italica） is one of the most valuable species in economic terms in the genus Setaria and plays an important role in human nutrition, animal feed, and agriculture. The present study described chemical, physical, and quality aspects of seeds of foxtail millet. Furthermore, the fluid-dynamic behavior of the seeds was evaluated in a conical spouted bed, which has advantages in terms of promoting the cyclic and regular movement of the seed particles. Dynamic parameters of spouting （minimum spouting veloc- ity, stable and peak pressure drop） were determined and compared with those obtained from empirical correlations available in the literature. The results obtained from physical characterization showed that the seeds can be classified as belonging to Group D of Geldart, having a non-rough surface, mean diameter of 1.75 mm, and sphericity of 0.74. Fluid-dynamics analysis showed that the seeds are suitable for processing in a spouted bed, which is in agreement with the results of particle physical characterization.

The present study consists of verifying the relation between life events mid intimacy and relational satisfaction in men from 40 years of age. The sample consisted of 70 males aged 40 years or older （M= 51.6, SD = 8.1）. In order to obtain the results, all the described life events were analyzed and the intimacy and relational satisfaction questionnaire, ＂Revised Dyadic Adjustment Scale＂（RDAS） was used. It was confirmed that there were significant differences in intimacy and relational satisfaction, comparing the subjects who pointed out very positive life events with the subjects who pointed out very negative life events. Regarding to the first group, there was a greater degree of satisfaction with intimacy, a greater agreement between the couple, a higher participation in joint activities and few disagreements within the relationship. However, the duration of the relationship and partner age are higher in the second group. It was also verified that subjects between 40 and 50 years old presented a higher degree of satisfaction with intimacy, comparing with subjects between 51 and 79 years, although the latter had longer relationships and that partner age was older.
