    Patients with bipolar disorder and schizophrenia often suffer from severe cognitive impairment even during times of remission. This study investigated the pathomechanisms underlying their deficits in cognitive control. A combined oddball-incongruence fMRI task was applied to examine similarities and differences of neural activation patterns between patients and healthy controls. Bipolar and schizophrenia patients demonstrated hyperactivations in the intraparietal cortex during the oddball condition. Furthermore, bipolar patients revealed diagnosis-specific hyperactivation in the left middle frontal gyrus, precentral gyrus, anteroventral prefrontal cortex and orbitofrontal cortex regions compared to schizophrenia patients and healthy individuals. In comparison to healthy controls the patients showed hypoactivations in the inferior frontal junction and ventral pathway during the cognitively more demanding incongruence. Taken together, bipolar patients seem to recruit frontal and parietal areas during the oddball condition to compensate for potential deficits in their attentional network. During more challenging tasks, i.e., the incongruence condition, their compensatory mechanisms seem to collapse leading to hypoactivations in the same frontal areas as well as the ventral pathway

Nomenclature: Names approved by the Antarctic Names Committee of Australia but are subject to confirmation (June 1991).Satellite image map of the Rauer Group, Antarctica. This map was produced for the Australian Antarctic Division by AUSLIG (now Geoscience Australia) Commercial, in Australia, in 1991. The map is at a scale of 1:50000, and was produced from two SPOT 1 scenes. It is projected on a Transverse Mercator projection, and shows refuge/depots and gives some historical text information.

    Rauer Group Geomorphology

    No full text
    Progress Code: completedThis dataset consists of spreadsheets with data about the geomorphology of the Rauer Group compiled by Dr Phil O'Brien. The spreadsheets refer to photos provided by Dr Duanne White, University of Canberra and collected during the expedition of the RV Polarstern (ANT-XXIII/9) in 2007. The photos are of landscapes and landforms and include metadata to allow their use as benchmark images for monitoring change and processes. Some images of human impacts are included to allow for estimates of the longevity of these features. The photos are available from the metadata record with ID Rauer_Group_Geomorphic_Map (see a provided URL)

    Rauer Group 1:50000 Topographic GIS Dataset

    No full text
    Progress Code: completedStatement: Owing to the surface conditions at the time of the photography small islands and lakes may not be present and the shapes of features may be incorrect. The topographic data covering the island group and coastal region has been sourced from ANARE aerial photography dated 1960 (films ANT97 and ANT75). Contours on ice where sourced from 1:100,000 and 1:200,000 scale Soviet mapping. SPOT XS satellite imagery (K281-J493 of 16/2/90) was used to define the seaward extent of glacier tongues. Owing to deficiencies in the aerial photography (no camera calibration or fiducial marks and insufficient overlays) and lack of ground control these data do not meet 1:50,000 mapping standards. Distortions of up to 50 metres are known to exist in the data. Note: The link to shapefile below links to all Rauer Group GIS data. This record refers specially to data with a dataset_id = 75.Rauer Group 1:50000 Topographic GIS dataset. Data conforms to SCAR Feature Catalogue which can be searched.<br/>10 metre contour interval on rock, 20 metre contour interval on ice up to 100 metres, 100 metre contour interval on ice above 100 metres

    Un moderno falso origeniano: sull’attribuzione e sui testimoni di Or. fr. 241-242 Rauer (90-91 Crouzel-Fournier-Périchon) in Lc.

    Following a critical remark by E. Prinzivalli, the article aims to show that two Greek fragments usually attributed to Origen (Or. fr. 241-242 Rauer (90-91 Crouzel-Fournier-Périchon) in Lc.) are actually spurious. The author demonstrates that M. Rauer linked the first fragment to Origen because he misread the lemma in the manuscript Par. Coisl. 612. Moreover, he identifies two “new” testimonies of the fragments (Vat. Pal. gr. 20, Vind. theol. gr. 117), in which they are both ascribed to Apollinaris of Laodicea. Indeed, several proofs indicate that Or. fr. 241-242 Rauer in Lc. should be attributed to Apollinaris, and should be published as one fragment, together with another small excerpt by Apollinaris (Apoll. fr. 11,5-6 Reuss in Lc.)

    Magnetotelluric investigation of the Vestfold Hills and Rauer Group, East Antarctica (time series)

    NAThis record was harvested by RDA at 2025-09-11T16:10:37.805841+10:00 from <a href='http://geonetwork.nci.org.au/geonetwork/srv/eng/catalog.search#/metadata/f2638_6708_6611_7301'>NCI's Data Catalogue</a> where it was last modified at 2019-06-04T12:06:15.The Vestfold Hills and Rauer Group in East Antarctica have contrasting Archean to Neoproterozoic geological histories and are believed to be juxtaposed along a suture zone that now lies beneath the Sørsdal Glacier. Exact location and age of this suture zone are unknown, as is its relationship to regional deformation associated with the amalgamation of East Gondwana. To image the suture zone, magnetotelluric (MT) data were collected in Prydz Bay, East Antarctica, mainly along a profile crossing the Sørsdal Glacier and regions inland of the Vestfold Hills and Rauer Group islands. 
 
 MT data were collected by a team from University of Adelaide with support from the Australian Antarctic Division (AAD) in the austral summer of 2008/2009. Thirty four stations were collected along three transects totaling approximately 200 line kilometers, with station spacing varying between 2.5 and 20 km . Instrumentation consisted of six AuScope MT systems using Numeric Resources preamplifiers to overcome the high contact impedance of ice. Magnetic data were variably collected using three-component fluxgate, and two-component (both horizontal) and three-component (two horizontal and one vertical) induction coil magnetometers. Stainless steel plates were used for electrodes (with the face placed horizon- tally in snow or ice) along 100 m dipoles setup in an L-shape. Data were collected for an average of 5 days at a sampling rate of 100 samples/s. All stations where aligned with geomagnetic north (81 degrees west of geographic north). The field team was stationed at the AAD’s Davis Station and transported between stations via helicopter

    Progress Code: completedOccupancy surveys in November 2008 (Southwell and Emmerson 2013) found a total of 13 Adélie penguin breeding sites in the Rauer Group. The boundaries of breeding sub-colonies at 12 of these sites were subsequently mapped from vertical aerial photographs taken for abundance surveys on 21-23 November 2009 (for details of aerial photography see Southwell et al. 2013). The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.<br/><br/>Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data

The boundaries of breeding sub-colonies at 12 of these sites were subsequently mapped from vertical aerial photographs taken for abundance surveys on 21-23 November 2009. The remaining breeding site (IS_72922) was photographed obliquely from a helicopter using a hand-held camera on 20 December 2010. Colony boundaries for this site were drawn and digitised by eye.<br/><br/>Please refer to the Seabird Conservation Team Data Sharing Policy for use, acknowledgement and availability of data prior to downloading data
