In this study two plasma sources were used for an in vivo treatment of human stratum corneum. The sample preparation was realised with the Cyanoacrylat stripping method, whereby a few layers of corneocytes embedded in the lipid matrix were removed from the skin of healthy volunteers. For the plasma treatment, dielectric barrier discharges with pulse durations in the microsecond as well as in the nanosecond range were applied. A comparison of these sources with respect to their biologically active components including dissipated power, gas and electron temperature, irradiance in the ultraviolet range, ozone and nitric oxide concentration is presented. Furthermore, species generated during plasma treatment on the sample surface like hydrogen peroxide, nitride or nitrate were measured using reflectometry. In addition, safety aspects for both sources were evaluated. Resulting plasma induced changes in the sample composition were investigated through X-ray photoelectron spectroscopy. The main ingredients carbon, oxygen, and nitrogen in addition to minor concentrations of sulphur were considered. A significant influence of the pulse duration on plasma characteristics was shown. A more effective formation of reactive species as well as more intense UV emission for ns-plasma was observed. Based on the determined parameters, both plasma sources are suitable for therapeutic purpose. Furthermore, significant plasma induced changes in the stratum corneum composition were reported, including an increase in nitrogen and oxygen content.

A wireless body area network （WBAN） enables real-time monitoring of physiological signals and helps with the early detection of life-threatening diseases. WBAN nodes can be located on, inside, or in close proximity to the body in order to detect vital signals. Measurements from sensors are processed and transmitted over wireless channels. Issues in sensing, signal processing, and com-munication have to be addressed before WBAN can be implemented. In this paper, we survey recent advances in research on sig-nal processing for the sensor measurements, and we describe aspects of communication based on IEEE 802.15.6. We also discuss state-of-the-art WBAN channel modeling in all the frequencies specified by IEEE 802.15.6 as well as the need for new channel models for new different frequencies.

针对放大转发(Amplify-forward,AF)方式下,虚拟多输入多输出(Virtual-multiple input multiple output,V-MIMO)系统中的功率分配问题,提出一种基于线性注水原理的低复杂度功率分配算法。该算法通过快速排除信道条件较差的协作用户,并利用各协作用户功率值之间的线性递推关系式,将最优功率分配算法中的迭代运算转化为线性运算,在实现功率快速分配的同时,达到显著降低算法复杂度的目的。瑞利信道下的仿真结果表明,采用该算法所获得的系统容量和中断概率性能与最优功率分配算法相当。

试验选择135头330±10kg杂交阉牛,采用完全随机区组化设计,旨在评估给在无芒雀麦牧草地放牧的1岁阉牛饲喂含玉米酒精糟(DDGS)替代饲草和氮养料对阉牛氮利用率的影响。分为3个处理组,阉牛按每公顷牧草地6.8头月单位(AUM)在不施氮肥的无芒雀麦牧草地放牧(CONT组);9.9AUM在每公顷施90kg氮的无芒雀麦牧草地放牧(FERT组);9.9AUM在不施氮肥的无芒雀麦牧草地放牧,每头阉牛每天添加DDGS2.3k(gSUPP组)。以围场作试验单元,每年每个处理3个重复,共3年。在160d放牧期中,围场实行条状放牧,采用减添牛的方法来维持围场之间相似的放牧强度。试验结果表明,阉牛采食较少的饲草(P<0.01),但是SUPP组每头阉牛、每公顷牧草地采食的总氮比FERT组多(P<0.01),而SUPP组和FERT组又比CONT组多(P<0.01)。与CONT组和FERT组相比,SUPP组阉牛的氮滞留提高31%(P<0.01)。SUPP组每公顷氮滞留比FERT组和CONT组分别高30%和98%。SUPP组每头阉牛、每公顷牧草地的氮排泄也比FERT组多(P<0.01),SUPP组和FERT组高于CONT组(P<0.01)。CONT组、FERT组和SUPP组阉牛的氮利用率相似(P=0.29)。与FERT组相比,SUPP组基于系统的氮利用改善144%(P<0.01)。试验结果表明,DDGS提高了1岁阉牛的氮采食量和氮排泄量。不过,由于体增重的提高和牧草地载畜量的增加,DDGS可作为无芒雀麦放牧制度提高氮利用率的有效方法。
