Study of b-jet tagging performance in ALICE

We present the current status and Monte Carlo study based performance estimates of b-jet tagging using ALICE, as obtained using both impact parameter as well as secondary vertex methods. We also address the prospects of the identification of electrons from heavy-flavour hadron decays to obtain b-jet enhanced jet samples.Comment: 3 pages, 5 figures, Proceedings of the Strangeness in Quark Matter Conference (SQM 2013), 22nd - 27th July 2013, published by the Open Access Journal of Physics: Conference Series (JPCS), in the IOP conference serie

Revegetation of Upper Elevation Debris Slide Scars on Mount Le Conte in the Great Smoky Mountains National Park

Vegetation and environmental data from nine debris slides on Mt. Le Conte were analyzed in this study. Ages of the debris slides ranged from 1.5 to about 50 years at the time of sampling in the summer of 1980. Vegetation was sampled using 50 cm x 50 cm plots along horizontal transects across each slide. Data collected in each plot included the percent cover of each vascular plant species as well as depth to impenetrable obstruction, bare rock cover, bryophyte cover and lichen cover. Debris slides were divided into vertical zones as horizontal zones based upon slide shape, slope angle and profile in cross-section. The first of the three vertical zones studied was the head zone at the top of the slide; the next lowest zone was the erosion-transportation zone; the lowest zone studied was the next one, the transportation-gully zone. A terminal zone, the deposition zone, was located below the transportation-gully zone but was not studied. Two horizontal zones, a center and margin at each lateral edge, were recognized. The effects of time on debris slide recovery and revegetation were noted. With increasing age, soil depth increased, bare rock cover decreased, and cover vascular plants, bryophytes, and lichens increased on most parts of each debris slide. Different trends in vegetation composition were noted among plots of the horizontal and vertical zones and among slides of different ages. Some species, such as Carex misera, were more frequent in the head zone rather than in the other two zones, while others, such as Saxifraga michauxii, occurred throughout. Individuals of certain species, for example, Carex misera, appeared with greater frequencies in young slides; other taxa, for example, Calamagrostis cainii, were found established only in older slides. Forbs and graminoids were the life forms occurring most frequently. Trees and shrubs were present less frequently in younger slides; numbers of individuals and cover increased from younger to older slides. Analysis of variance indicated significant differences among vertical zones and horizontal zones as well as among slide age classes. Data used were mean values of depth to rooting obstruction, bare rock cover, bryophyte cover and lichen cover. Seven community types were separated at the 45 percent dispersion level using cluster analysis. Three of these types, the Saxifraga michauxii type, the mixed herb type, and the Carex misera types were found in young slides and highly disturbed areas of somewhat older slides. Four community types, the Solidago glomerata type, the Diervilla sessilifolia type, the Rubis canadensis type, and the Calamagrostis cainii type, were found only in recovering, older slides. Debris slides are dynamic areas but subject to ongoing natural disturbance. Successful colonizers appear to be stress-tolerant species able to withstand recurrent disturbance. Several rare vascular plant species, such as Gentiana linearis, Krigia montana, and Calamagrostis cainii, which require non-forest sites at high elevations were found in these debris slides

The effectiveness of electronic whiteboards and powerpoint lessons in the mathematics classroom

A popular method of teaching in today’s k-12 classroom is standardizing lessons on Microsoft office’s PowerPoint. Another tool which is starting to become more common in classrooms is electronic white boards, which are similar to smart boards. Attempting to discover the most effective way to teach in the math classroom, I investigated these techniques at a local school

Giving the devil his due: The emergence of the fallen hero in English literature

In 1637, John Milton wrote Paradise Lost, which presented the story of Satan’s fall from heaven. From this text, a humanized Satan was born who, despite his evil vices, consisted of heroic traits which future authors loved. Milton’s Satan became the model for future Romantic Authors including Lord George Byron. By examining specific influences in the late 1700’s, one can understand how the Prince of Darkness evolved into a tragic hero

The Measurement of Human Chorionic Gonadotropin for Pregnancy Testing

/Among many measurable hormones, human chorionic gonadotropin (FICG) is commonly used for pregnancy testing because it is very sensitive and relatively specific. Pregnancy can be identified shortly after implantation. Because some reagents cross-react with luteinizing hormone (LH), the sensitivity of urine tests has been adjusted to maintain specificity. Radioreceptor assay s on serum are more sensitive than urine tests but similarly lack specificity. The problems of LH cross-reactivity are eliminated by antisera specific for the beta subunit. Quantitation of HCG provides additional information useful in diagnosing ectopic pregnancy, providing a prognosis in threatened abortion, and following neoplasms. Considerations of cost, availability, accuracy, and sensitivity determine which test should be selected

Visualization and Interaction for Knowledge Discovery in Simulation Data

Discrete-event simulation is an established and popular technology for investigating the dynamic behavior of complex manufacturing and logistics systems. Besides traditional simulation studies that focus on single model aspects, data farming describes an approach for using the simulation model as a data generator for broad scale experimentation with a broader coverage of the system behavior. On top of that we developed a process called knowledge discovery in simulation data that enhances the data farming concept by using data mining methods for the data analysis. In order to uncover patterns and causal relationships in the model, a visually guided analysis then enables an exploratory data analysis. While our previous work mainly focused on the application of suitable data mining methods, we address suitable visualization and interaction methods in this paper. We present those in a conceptual framework followed by an exemplary demonstration in an academic case study

Structural and Energetic Determinants of Apo Calmodulin Binding to the IQ Motif of the NaV1.2 Voltage-Dependent Sodium Channel

SummaryThe neuronal voltage-dependent sodium channel (Nav1.2), essential for generation and propagation of action potentials, is regulated by calmodulin (CaM) binding to the IQ motif in its α subunit. A peptide (Nav1.2IQp, KRKQEEVSAIVIQRAYRRYLLKQKVKK) representing the IQ motif had higher affinity for apo CaM than (Ca2+)4-CaM. Association was mediated solely by the C-domain of CaM. A solution structure (2KXW.pdb) of apo 13C,15N-CaM C-domain bound to Nav1.2IQp was determined with NMR. The region of Nav1.2IQp bound to CaM was helical; R1902, an Nav1.2 residue implicated in familial autism, did not contact CaM. The apo C-domain of CaM in this complex shares features of the same domain bound to myosin V IQ motifs (2IX7) and bound to an SK channel peptide (1G4Y) that does not contain an IQ motif. Thermodynamic and structural studies of CaM-Nav1.2IQp interactions show that apo and (Ca2+)4-CaM adopt distinct conformations that both permit tight association with Nav1.2IQp during gating
