Vast magnetospheric regions are mapped along the field lines to the narrow latitudinal band of the polar/auroral regions. Therefore monitoring of solar wind energy dissipation into the ionosphere at auroral latitudes gives unique opportunities to study geomagnetic disturbances in their complexity from a relatively well-localized vantage point. Here we introduce and present the current state of a recently proposed science project for coordinated monitoring of high-latitude activity with the EISCAT (European Incoherent Scatter) radar array supported by ground-based magnetometer and optical data and ENA (Energetic Neutral Atom) observation from the CINEMA (Cube-Sat for Ions, Neutrals, Electrons and Magnetic field) satellite system.

In this paper, we present a non-linear (multi-affine) registration algorithm based on a local polynomial expansion model. We generalize previous work using a quadratic polynomial expansion model. Local affine models are estimated using this generalized model analytically and iteratively, and combined to a deformable registration algorithm. Experiments show that the affine parameter calculations derived from this quadratic model are more accurate than using a linear model. Experiments further indicate that the multi-affine deformable registration method can handle complex non-linear deformation fields necessary for deformable registration, and a faster convergent rate is verified from our comparison experiment.

AIM To investigate changes in hepatic and splenic stiffness in patients without chronic liver disease during liver resection for hepatic *** Patients scheduled for liver resection for hepatic tumors were considered for enrollment. Tissue stiffness measurements on liver and spleen were conducted before and two days after liver resection using point shear-wave elastography. Histological analysis of the resected liver specimen was conducted in all patients and patients with marked liver fibrosis were excluded from further study analysis. Patients were divided into groups depending on size of resection and whether they had received preoperative chemotherapy or not. The relation between tissue stiffness and postoperative biochemistry was investigated. RESULTS Results are presented as median(interquartile range). 35 patients were included. The liver stiffness increased in patients undergoing a major resection from 1.41(1.24-1.63) m/s to 2.20(1.72-2.44) m/s(P = 0.001). No change in liver stiffness in patients undergoing a minor resection was found [1.31(1.15-1.52) m/s vs 1.37(1.12-1.77) m/s, P = 0.438]. A major resection resulted in a 16%(7%-33%) increase in spleen stiffness, more(P = 0.047) than after a minor resection [2(-1-13) %]. Patients who underwent preoperative chemotherapy(n = 20) did not differ from others in preoperative right liver lobe [1.31(1.16-1.50) vs 1.38(1.12-1.56) m/s, P = 0.569] or spleen [2.79(2.33-3.11) vs 2.71(2.37-2.86) m/s, P = 0.515] stiffness. Remnant liver stiffness on the second postoperative day did not show strong correlations with maximum postoperative increase in bilirubin(R^2 = 0.154, Pearson's r = 0.392, P = 0.032) and international normalized ratio(R^2 = 0.285, Pearson's r = 0.534, P = 0.003). CONCLUSION Liver and spleen stiffness increase after a major liver resection for hepatic tumors in patients without chronic liver disease.

为了了解Storegga滑坡的成因机制，在滑坡附近区域的钻孔中取了一系列样品进行矿物学及微细构造分析。结果表明，从Brygge（始新世-早中新世）到Kai（早中新世-晚上新世）一直到Naust层（晚上新世-现在），岩性分别为富高岭石软泥-富蒙脱石含化石的粘土质软泥-伊利石为主的半远洋沉积和冰期沉积。我们认为这些沉积物是风化层剥蚀、气候变冷时物理风化作用加剧以及晚新生代冰川作用周期开始发育共同影响的结果。第四纪沉积受气候控制，洋流搬运物质发生混合，细粒沉积物可能来自法罗群岛周边地区，具有宽矿物光谱的较粗粒冰期沉积来自北海和斯堪的纳威亚大陆。在温暖气候期，洋流是最重要的控制因素，因此此时形成的沉积物粒度较细，且比冰期沉积含更高的蒙脱石。可以肯定的是温暖气候期形成的细粒沉积与冰期较粗粒沉积之间矿物组成的不同并不能解释本区冰期海相／半远洋沉积作为滑坡滑动面这一现象，我们认为造成这一现象的原因可能在于沉积物粒径的变化。另外，观察到了某种特殊孔洞，这种孔洞可能是气体水合物分解留下的痕迹。

本文采用让受访问者做选择题的办法,研究来自农业的食品品质特性与消费者支付意愿的关系,目前这些食品在瑞典还没有销售。数据是通过大规模的邮件调查获得的,同时用一个随机参数的Logit模型来估计。我们的结果表明:同一产品和相同特性,消费者的支付意愿均存在差异。不同产品间为品质特性排序时也是这样。而且,我们还发现可能以转基因作物作为饲料的动物食品市场上表现不力。最后,我们的结论支持被称作"cheap-talk"的研究方法能有效地减小选择试验地的外在误差。在食品行业冲,我们的结论对产品差别化战略的构建和对食品政策的形成等方面十分有用。

我们使用Nest决策支持系统中的耦合模型,评估海洋生态系统对通过各种管理选择引起的外来负荷变化的反应。模型涉及所有7个主要海盆和波罗的海的整个流域。在与赫尔辛基委员会的密切合作下,开发了一系列的未来情景,来了解改善废水处理和粪肥处理、无磷洗涤剂和较低强度的土地利用和家畜的可能作用。废水处理的改善和无磷洗涤剂在整个区域的使用,将明显地减少磷的负荷,并改善海洋环境,尤其是蓝藻细菌藻华的发生。但是,波罗的海仍是富营养的,而为了减少其它影响,必须实行大量减少氮的排放。在这些情景下只能通过强烈地改变土地利用方式来实现这一点。在最后的情景中,我们把所有农田的50%变成草地,实行高效率的废水处理和在洗涤剂中禁用磷。这将会大大地减少初级生产量和缺氧底层的扩大,增加富营养化最严重的海盆水的透明度,以及从根本上消灭蓝藻细菌藻华的大规模泛滥。
