A passive three stimulus oddball paradigm was used to investigate Visual Mismatch Negativity (vMMN) a component of the Event Related Potential (ERP) believed to represent a central pre-attentive change mechanism. Responses to a change in orientation were recorded to monochrome stimuli presented to subjects on a computer screen. One of the infrequent stimuli formed an illusory figure (Kanizsa Square) aimed to capture spatial attention in the absence of an active task. Nineteen electrodes (10-20 system) were used to record the electroencephalogram in fourteen subjects (ten females) mean age 34.5 years. ERPs to all stimuli consisted of a positive negative positive complex recorded maximally over lateral occipital areas. The negative component was greater for deviant and illusory deviant compared to standard stimuli in a time window of 170-190 ms. A P3a component over frontal/central electrodes to the illusory deviant but not to the deviant stimulus suggests the illusory figure was able to capture attention and orientate subjects to the recording. Subtraction waveforms revealed visual discrimination responses at occipital electrodes, which may represent vMMN. In a control study with 13 subjects (11 females; mean age 29.23 years), using an embedded active attention task, we confirmed the existence of an earlier (150-170 ms) and attenuated vMMN. Recordings from an intracranial case study confirmed separation of N1 and discrimination components to posterior and anterior occipital areas, respectively. We conclude that although the illusory figure captured spatial attention in its own right it did not draw sufficient attentional resources from the standard-deviant comparison as revealed when using a concurrent active task.

The infrastructure cloud (IaaS) service model offers improved resource flexibility and availability, where tenants - insulated from the minutiae of hardware maintenance - rent computing resources to deploy and operate complex systems. Large-scale services running on IaaS platforms demonstrate the viability of this model; nevertheless, many organizations operating on sensitive data avoid migrating operations to IaaS platforms due to security concerns. In this paper, we describe a framework for data and operation security in IaaS, consisting of protocols for a trusted launch of virtual machines and domain-based storage protection. We continue with an extensive theoretical analysis with proofs about protocol resistance against attacks in the defined threat model. The protocols allow trust to be established by remotely attesting host platform configuration prior to launching guest virtual machines and ensure confidentiality of data in remote storage, with encryption keys maintained outside of the IaaS domain. Presented experimental results demonstrate the validity and efficiency of the proposed protocols. The framework prototype was implemented on a test bed operating a public electronic health record system, showing that the proposed protocols can be integrated into existing cloud environments.

Onshore, the Piacenzianof the Mondego and Lower Tagus Tertiary basins comprises siliciclastic sediments deposited in shallow marine to continental environments. The outcrops of the deposits are relatively widespread in the Aveiro and Seuibal region. A lithostratigraphic synthesis based on the correlation of geological sections, is presented for the two basins. In general, the Piacenzian sediments display a regressive sucession. The Late Tortonian-Zanclean (?) confined drainage pattern changed at the beginning of Piazencian, to fluvial systems draining to the Atlantic, and capturing the drainage of the inner parts of the Hesperic Meseta. The Piacenzian sedimentary sequence post-dates one of the uprising phases during Neogene compression, recorded by a strong regional unconformity. Some local active faulting - as in Lousa, Rio Maior and Senibal- Pinhal Novo - allowed the local thickening of the sedimentary record. Later compressive tectonism continues to generate reverse faulting and diapiric reactivation, affecting those sediments. Currently, the Piacenzian deposits culminates the marginal piedmonts, widely eroded by the Quaternary fluvial dissection.

A national survey conducted in Switzerland aimed to evaluate the knowledge of physiotherapists regarding the legal requirements for record keeping and to collect their feedback about record keeping in general. Three physiotherapists from various professional practice groups and a lawyer specialised in health law developed a questionnaire that was sent to the 7,753 members of two existing national associations of physiotherapists. The questionnaire evaluated the participants' knowledge by calculating a score of legal knowledge, which had a maximum of 30 points. We included 825 questionnaires in the analysis. The large majority (83.4%) of participants confessed an ignorance of the legal requirements concerning record keeping prior to the survey. The average score of legal compatibility was 8 points. The younger age of the physiotherapists was a significant predictor of having knowledge of the legal requirements for record keeping (p <0.001). The participants had an appreciation of the value of records, but they did not have the relevant knowledge regarding the legal requirements for keeping records. The participants blamed a lack of time and remuneration for their failure to keep records according to known requirements. All practising allied health professionals should keep up-to-date and accurate records that conform to active legal requirements and existing international guidelines. In addition to the existing legal requirements, the emergence of e-health and the electronic era will trigger major changes in patient record management by physiotherapists.
