一种EEG信号盲分离和分类的神经网络方法

提出一种采用多神经网络处理脑电(EEG)信号的方法。首先，对混有噪声的脑电信号给出一种盲分离的自适应神经算法。通过寻求采样时间序列线性组合的kurtosis系数的局部极值，得出该算法的模型和步骤。在盲分离的基础上，对分离出的估计信号进一步利用Kohonen网络进行分类。将该算法用于300个EEG样本处理，并给出处理结果。     

Separation distress and attachment in surrogate-reared squirrel monkeys.

Surrogate-reared infant squirrel monkeys were exposed to various conditions of separation from their surrogate. Infants showed significant increases in plasma levels of cortisol when they were placed in an unfamiliar environment during the separation period. Changes in behavior, but not cortisol, were observed under conditions in which the surrogate was removed and the infant left in the home cage. These results differ from those previously obtained with mother-reared infants. It is concluded that surrogate-reared infant squirrel monkeys do not show the same separation response or attachment to their rearing figure as do mother-reared infants.     

The effects of separation and reunion on the behavior of mother and infant squirrel monkeys

Mother and infant squirrel monkeys that lived together in a socially restricted environment were separated for a period of seven days after the infants had become relatively independent, and were then reunited. Behavioral observations before, during, and after separation indicated that (1) female infants became independent of their mothers earlier than males, (2) neither mothers nor infants were severely affected by separation, and (3) an increase in attachment occurred following reunion only when the mother had a limited history of maternal experience. These results suggest that (1) certain characteristics in the maternal behavior of the squirrel monkey facilitate readjustment in mothers and infants following maternal separation, (2) maternal experience can influence the mother-infant relationship following a period of separation, and (3) the independence of infants from their mothers may be a function of both sex and species.

Reconnecting with relational values in highly conflicted separating couples: A narrative therapy-informed relational interviewing teamwork-based supervision approach

This article outlines a new supervision practice of narrative therapy-informed reflecting team-based relational interviewing for a high-conflict stuck case of a separated middle-aged couple. The article demonstrates the supervision method consisting in five parts. First, the supervisor interviews the couples' relationship while the team watches from behind the one-way mirror. Second, the team responds to the interview while the couple and the supervisor witness their conversation. The couple is then invited to respond back to the team. Furthermore, there is a meta-conversation about the supervision in collaboration with the couple. The intervention ends with therapeutic letter writing to the relationship. The couple showed a meaningful shift in their positioning towards a more relational awareness and found valuable ways for continuing their therapy. The theoretical elements of the approach underpinning practice to tackle high conflict are considered through the illustration of the case.     

UV-Cured PDMS for Oil Removal from Wastewater

The removal of oil from water is a worldwide challenge that must be faced to avoid irreversible marine habitat destruction. A novel fast and simple technique to obtain polydimethylsiloxane (PDMS) membranes is developed using the photopolymerization technique. The high reactivity of the acrylated PDMS formulation toward photo-induced free radical polymerization is assessed via the differential scanning photo-calorimetry (photo-DSC) technique. Two different membranes dense or porous are developed and investigated. Porous membranes, having 100–200 µm as pore size, are obtained using a low-cost environmentally friendly sodium chloride template. Thanks to the hydrophobic/oleophilic intrinsic characteristic of PDMS, the UV-cured membranes can selectively remove dodecane, selected as the target oil, from water. The dodecane sorption capability of both membranes is investigated and compared. Moreover, the membranes can be easily reused since the adsorbed oil can be recovered by simply compressing the membrane. Those PDMS sorbents show high mechanical stability after five adsorption/desorption cycles.
