CernVM Online and Cloud Gateway: a uniform interface for CernVM contextualization and deployment

In a virtualized environment, contextualization is the process of configuring a VM instance for the needs of various deployment use cases. Contextualization in CernVM can be done by passing a handwritten context to the user data field of cloud APIs, when running CernVM on the cloud, or by using CernVM web interface when running the VM locally. CernVM Online is a publicly accessible web interface that unifies these two procedures. A user is able to define, store and share CernVM contexts using CernVM Online and then apply them either in a cloud by using CernVM Cloud Gateway or on a local VM with the single-step pairing mechanism. CernVM Cloud Gateway is a distributed system that provides a single interface to use multiple and different clouds (by location or type, private or public). Cloud gateway has been so far integrated with OpenNebula, CloudStack and EC2 tools interfaces. A user, with access to a number of clouds, can run CernVM cloud agents that will communicate with these clouds using their interfaces, and then use one single interface to deploy and scale CernVM clusters. CernVM clusters are defined in CernVM Online and consist of a set of CernVM instances that are contextualized and can communicate with each other.Comment: Conference paper at the 2013 Computing in High Energy Physics (CHEP) Conference, Amsterda

Micro-CernVM: Slashing the Cost of Building and Deploying Virtual Machines

The traditional virtual machine building and and deployment process is centered around the virtual machine hard disk image. The packages comprising the VM operating system are carefully selected, hard disk images are built for a variety of different hypervisors, and images have to be distributed and decompressed in order to instantiate a virtual machine. Within the HEP community, the CernVM File System has been established in order to decouple the distribution from the experiment software from the building and distribution of the VM hard disk images. We show how to get rid of such pre-built hard disk images altogether. Due to the high requirements on POSIX compliance imposed by HEP application software, CernVM-FS can also be used to host and boot a Linux operating system. This allows the use of a tiny bootable CD image that comprises only a Linux kernel while the rest of the operating system is provided on demand by CernVM-FS. This approach speeds up the initial instantiation time and reduces virtual machine image sizes by an order of magnitude. Furthermore, security updates can be distributed instantaneously through CernVM-FS. By leveraging the fact that CernVM-FS is a versioning file system, a historic analysis environment can be easily re-spawned by selecting the corresponding CernVM-FS file system snapshot.Comment: Conference paper at the 2013 Computing in High Energy Physics (CHEP) Conference, Amsterda

Gambaran Skor Pediatric Early Warning Score (Pews) pada Pola Rujukan Pasien Anak di Instalasi Gawat Darurat

An early warning score for children like PEWS (pediatric early warning score) has an ability to identify clinical deterioration of children and intervension can be taken before children condition become worst. The rapid response like increasing monitoring of children or transferring to intensive care unit. The aim of this research was to described PEWS of each transferring method for children in emergency department. This research used 85 respondents who admitted to the hospital in emergency department during 14 March – 14 June 2014. The respondents were taken by consecutive sampling method where children 0 – 18 years old evaluated by PEWS and then followed where the children being transferred based on doctor advice. After that the result presented by simple frequency distribution. The analysis found that children who adviced to went home have score ≤ 2, children who have score 3, 4, 5 transferred to inpatient ward and children who have score ≥ 6 transferred to NICU/PICU. This research recommended for nurses especially nurses at emergency department in a hospital to use PEWS to anticipate clinical deterioration of children in emergency department

On the use of nestedness-based similarity functions (NBSF) to classify and/or order operational geographic units (OGUs)

Abstract In this paper, we want to support the idea of using a family of indices of similarity, that we call the Simpson's family indices or nestedness-based similarity functions (NBSF) for comparing operational geographic units (OGUs) (phytosociological relevés, animal traps, watersheds, administrative units, industrial areas, islands etc.). In these cases, similarity-dissimilarity depends, in addition to factors that induce replacement, also on factors that produce reduction or increment in the number of features within the same typology of OGUs (e.g., extent, reduction of fertility, anthropogenic pressure etc.). To keep into consideration this aspect, the indices are defined to be equal to 1 when the OGUs are completely nested. The results of the application to four simulated data sets prove that, when the data set does not show clear nested pattern, the use of NBSF produces results similar to the nestedness-free similarity functions, however since NBSF clearly detect nested situations, we should prefer their use in the circumstances where we think important to put in evidence nestedness. In conclusion, we support the idea of using both types of indices in order to improve the knowledge about the structure of any data set

Spontaneous Vicarious Perception of the Content of Another’s Visual Perspective

Visual perspective taking (VPT) is a core process of social cognition, providing humans with insights into how the environment looks from another’s point of view [1-4]. While VPT is often described as a quasi-perceptual phenomenon [5,6], evidence for this proposal has been lacking. Here we provide direct evidence that another’s perspective can “stand in” for own sensory input perceptual decision-making. In a variant of the classic mental rotation task, participants judged whether characters presented in different orientations were canonical or mirror-inverted. In the absence of another person, we replicate the well-established positive linear relationship between recognition times and angle of orientation, such that recognition becomes slower the more an item has to be mentally rotated into its canonical orientation [18]. Importantly, this relationship was disrupted simply by placing another individual in the scene. Items rotated away from the participant were recognised more rapidly not only the closer they appeared in their canonical orientation to the participant but also to this other individual, showing that another’s visual perspective drives mental rotation and item recognition in a similar way as one’s own. The effects were large and replicated in the three independent studies. They were observed even when the other person was completely passive, enhanced for explicit instructions to perspective-take, but reduced when the persons in the scenes were replaced with objects. The content of another’s perspective is therefore spontaneously derived, takes a quasi-perceptual form, and can stand in for own sensory input during perceptual decision-making

Perspective taking as virtual navigation? Perceptual simulation of what others see reflects their location in space but not their gaze

Other peoples' (imagined) visual perspectives are represented perceptually in a similar way to our own, and can drive bottom-up processes in the same way as own perceptual input (Ward, Ganis, & Bach, 2019). Here we test directly whether visual perspective taking is driven by where another person is looking, or whether these perceptual simulations represent their position in space more generally. Across two experiments, we asked participants to identify whether alphanumeric characters, presented at one of eight possible orientations away from upright, were presented normally, or in their mirror-inverted form (e.g. “R” vs. “Я”). In some scenes, a person would appear sitting to the left or the right of the participant. We manipulated either between-trials (Experiment 1) or between-subjects (Experiment 2), the gaze-direction of the inserted person, such that they either (1) looked towards the to-be-judged item, (2) averted their gaze away from the participant, or (3) gazed out towards the participant (Exp. 2 only). In the absence of another person, we replicated the well-established mental rotation effect, where recognition of items becomes slower the more items are oriented away from upright (e.g. Shepard and Meltzer, 1971). Crucially, in both experiments and in all conditions, this response pattern changed when another person was inserted into the scene. People spontaneously took the perspective of the other person and made faster judgements about the presented items in their presence if the characters were oriented towards upright to them. The gaze direction of this other person did not influence these effects. We propose that visual perspective taking is therefore a general spatial-navigational ability, allowing us to calculate more easily how a scene would (in principle) look from another position in space, and that such calculations reflect the spatial location of another person, but not their gaze

Zebrafish globin switching occures in two developmental stages and is controlled by the LCR

Globin gene switching is a complex, highly regulated process allowing expression of distinct globin genes at specific developmental stages. Here, for the first time, we have characterized all of the zebrafish globins based on the completed genomic sequence. Two distinct chromosomal loci, termed major (chromosome 3) and minor (chromosome 12), harbor the globin genes containing α/β pairs in a 5'-3' to 3'-5' orientation. Both these loci share synteny with the mammalian α-globin locus. Zebrafish globin expression was assayed during development and demonstrated two globin switches, similar to human development. A conserved regulatory element, the locus control region (LCR), was revealed by analyzing DNase I hypersensitive sites, H3K4 trimethylation marks and GATA1 binding sites. Surprisingly, the position of these sites with relation to the globin genes is evolutionarily conserved, despite a lack of overall sequence conservation. Motifs within the zebrafish LCR include CACCC, GATA, and NFE2 sites, suggesting functional interactions with known transcription factors but not the same LCR architecture. Functional homology to the mammalian α-LCR MCS-R2 region was confirmed by robust and specific reporter expression in erythrocytes of transgenic zebrafish. Our studies provide a comprehensive characterization of the zebrafish globin loci and clarify the regulation of globin switching

Amplification of The GAPDH Gene from The Urine eDNA of Sumatran Rhino in Sumatran Rhino Sanctuary, Way Kambas National Park

Profiling the genetic character of each individual sumatran rhino is important in order to maintain individual viability and genetic variability of Sumatran rhinos. Non-invasive sampling is needed to minimize the disturbance of individual sumatran rhinos, this is due to the solitary character of sumatran rhinos and tend to be afraid to interact with humans. Until now, non-invasive sampling of sumatran rhinos in Way Kambas National Park (WKNP) has only been done through the source of the puddle. This study aims to amplify the GAPDH gene from sumatran rhino environmental DNA (eDNA) sourced from urine. Urine sampling was carried out on four of the eight sumatran rhino individuals in WKNP. DNA extraction of four sumatran rhino urine samples was carried out with reference to the DNeasy® Blood &amp; tissue kit extraction protocol. Amplification of eDNA extraction results was carried out by polymerase chain reaction (PCR) using GAPDH primers. Visualization of extraction and amplification results from four individual sumatran rhinos at TNWK was tested qualitatively with 1% agarose gel electrophoresis. Electrophoresis results showed positive results after amplification of four individual sumatran rhino urine samples at sizes between 100-200bp. This study successfully amplified the GAPDH gene from four sumatran rhino individuals in WKNP based on qualitative tests. In further conservation efforts, it is necessary to explore eDNA extraction from other potential sources
