    Description: Sediments cored along the southwestern Iberian margin during Integrated Ocean Drilling Program Expedition 339 provide constraints on Mediterranean Outflow Water (MOW) circulation patterns from the Pliocene epoch to the present day. After the Strait of Gibraltar opened (5.33 million years ago), a limited volume of MOW entered the Atlantic. Depositional hiatuses indicate erosion by bottom currents related to higher volumes of MOW circulating into the North Atlantic, beginning in the late Pliocene. The hiatuses coincide with regional tectonic events and changes in global thermohaline circulation (THC). This suggests that MOW influenced Atlantic Meridional Overturning Circulation (AMOC), THC, and climatic shifts by contributing a component of warm, saline water to northern latitudes while in turn being influenced by plate tectonics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hernandez-Molina, F Javier -- Stow, Dorrik A V -- Alvarez-Zarikian, Carlos A -- Acton, Gary -- Bahr, Andre -- Balestra, Barbara -- Ducassou, Emmanuelle -- Flood, Roger -- Flores, Jose-Abel -- Furota, Satoshi -- Grunert, Patrick -- Hodell, David -- Jimenez-Espejo, Francisco -- Kim, Jin Kyoung -- Krissek, Lawrence -- Kuroda, Junichiro -- Li, Baohua -- Llave, Estefania -- Lofi, Johanna -- Lourens, Lucas -- Miller, Madeline -- Nanayama, Futoshi -- Nishida, Naohisa -- Richter, Carl -- Roque, Cristina -- Pereira, Helder -- Sanchez Goni, Maria Fernanda -- Sierro, Francisco J -- Singh, Arun Deo -- Sloss, Craig -- Takashimizu, Yasuhiro -- Tzanova, Alexandrina -- Voelker, Antje -- Williams, Trevor -- Xuan, Chuang -- New York, N.Y. -- Science. 2014 Jun 13;344(6189):1244-50. doi: 10.1126/science.1251306.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Royal Holloway, University of London, Egham, Surrey TW20 0EX, UK. javier.hernandez-molina@rhul.ac.uk. ; Institute of Petroleum Engineering, Heriot-Watt University, Edinburgh EH14 4AS, Scotland, UK. ; International Ocean Discovery Program, Department of Oceanography, Texas A&M University, College Station, TX 77845, USA. ; Department of Geography and Geology, Sam Houston State University, Huntsville, TX 77341, USA. ; Institute of Geosciences, University of Frankfurt, 60438 Frankfurt, Germany. ; Institute of Marine Sciences, University of California, Santa Cruz, CA 95064, USA. ; EPOC, Universite de Bordeaux, 33615 Pessac Cedex, France. ; School of Marine and Atmospheric Sciences, Stony Brook University, Stony Brook, NY 11794, USA. ; Departamento de Geologia, Universidad de Salamanca, 3008 Salamanca, Spain. ; Department of Natural History Sciences, Hokkaido University, N10W8, Kita-ku, Sapporo 060-0810, Japan. ; Institute for Earth Sciences, University of Graz, A-8010 Graz, Austria. ; Godwin Laboratory for Palaeoclimate Research, University of Cambridge, Cambridge CB2 3EQ, UK. ; Department of Biogeochemistry, JAMSTEC, 237-0061 Yokosuka, Japan. ; Korea Institute of Ocean Science & Technology, Ansan 426-744, Korea. ; School of Earth Sciences, Ohio State University, Columbus, OH 43210, USA. ; Institute for Frontier Research on Earth Evolution (IFREE), JAMSTEC, 2-15 Natsushima-Cho, Yokosuka-city, Kanagawa 237-0061, Japan. ; Department of Micropalaeontology, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, P.R.

    Notes: Summary The use of a 20 MHz pulsed Doppler technique during stereotactic brain tumour biopsies is described. By means of a miniaturized ultrasonic probe the tissue planned for biopsy was investigated for vessel signals. Out of 41 patients, with this technique a flow-pulse curve in front of the biopsy cannula was registered in 14 cases. In 9 cases one pulse curve was determined and in 5 cases two or more flow curves were found, indicating the presence of arterial vessels. The depth of the vesses signal could be localized and this area avoided for biopsy sampling. In a series of 41 Stereotactic biopsies carried out in this way there was no intra-operative haemorrhage or postoperative haematoma.

    Notes: Abstract  The accuracy of coordinate transformation from the computed tomographic (CT) space to the stereotactic frame space was analysed for frame-based stereotactic systems which use a localisation frame and coordinate transformation based on matrix calculation. The coordinate transformation was divided into three consecutive steps: (1) transforming the localisation frame into the CT image built up from pixels with distinct attenuation values, (2) determining the rod centres of the localisation frame in the CT image, and (3) coordinate transformation from the image to the frame space using the centres of the rods in the image space and algebraic, matrix-based calculation. The error contribution at each step was evaluated separately and its effect on the subsequent mathematical operations was analysed. The first step dealt with the influences of the mathematical and physical properties of the CT on the image of the localisation frame. Noise, slice thickness, convolution filter, dimension of the pixel matrix, and image processing had an influence on the attenuation values in each pixel. Above all, the slice thickness had an effect on the shape of the oblique rods in the CT image. At the second step, the main error contribution was due to the method by which the centre of the rods was calculated. The most accurate method was to determine the centre of gravity using the attenuation values as single mass points (with accuracy in the range of ±1/10 pixel, or ±0.125 mm), followed by rounding off the centre of gravity and the highest pixel value in the square matrix R2(N) within 1 pixel. Pointing with a cursor under visual control was accurate to 1 pixel and the pixel with the highest attenuation value showed deviations of up to 2 pixels in the x and y axes. Thus, the methods differed by a factor of 20. The influence of the CT mathematics and physics on the determination of the centre of the fiducials was negligible in comparison to the method of calculation used. There was no systemic error due to the filtred back projection algorithm. Data input errors due to noise were in the range of 1/10 pixel. The effects of the remaining physical influences were all in the range of the error due to noise. In particular these results speak in favour of no influence of slice thickness on coordinate transformation.
