Measurement of the jet mass and angularities in Pb-Pb collisions at 5.02 TeV with ALICE

Jet substructure observables provide powerful tools to search for new physics and test theoretical descriptions of perturbative and non-perturbative processes in QCD. In heavy-ion collisions, jet substructure observables are used to elucidate the structure and dynamics of the quark-gluon plasma. Jet mass is one such observable, which probes the virtuality of hard-scattered partons and their modified fragmentation. Additionally, generalized jet angularities provide a powerful tool for differential measurements of the jet shower and its modification, as two parameters vary the weight of the jet constituents' relative angle and $p_\mathrm{T}$. Previous measurements of the jet mass and jet angularities have shown conflicting differences in comparison with models. To clarify these results, we present new measurements of the jet mass and jet angularities using an identical jet sample. The high-precision tracking system of ALICE enables these measurements over a broad range in $p_\mathrm{T}$, with low-$p_\mathrm{T}$ reach that is unique at the LHC. We report the generalized jet mass and jet angularities using charged-particle tracks in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV. Various jet angularity parameters are investigated for the jet resolution parameter $R = 0.2$. Results are compared to pp collisions and theoretical models.Comment: 6 pages, 3 figures.

Detecting Fires: A Nationally Consistent, Rule Based Approach

One of the continuing challenges in wildland fire management is maintaining accurate vegetation and fuel data of an adequate resolution on an ever-changing landscape. The USGS’s LANDFIRE program produces national, mid-level resolution datasets of fuel, vegetation, and fire regime data useful in the modeling of wildland fire behavior. One of the most effective and least expensive ways for maintaining the accuracy of these layers is to incorporate area updates by detecting landscape changes. While many algorithms exist for detecting change and disturbances, these algorithms are often tuned for a particular landscape and require very precise training data or rely heavily on scene statistics. This research looks at a method for detecting wildland fire across a broad array of landscapes using a collection of computer-generated rules built from hundreds of thousands of points of training data. Verification of the results were assessed by visual comparison to a time series of high spatial resolution imagery through Google Earth and cross-referenced to fires from various historical databases. A majority of the fires detected in this assessment were in either a conifer or grassland landscape. The methods outlined in this thesis performed best in those two landscapes, detecting 73% to 78% of conifer fires correctly and 79% to 83% of grassland fires correctly

Ohio Hazardous Material Transportation Act: An Overview

On June 24, 1988, in Miamisburg, Ohio, Governor Richard F. Celeste signed into law H.B. 428, (known as Ohio\u27s Hazardous Material Transportation Act, hereinafter referred to as the Act) a comprehensive legislative initiative regulating the transportation of hazardous materials. The signing of the Act was the culmination of a two year effort to solve a problem that Ohioians, and the nation as a whole, became aware of in July, 1986 in Miamisburg, Ohio. The new law provides for: a registration system with a graduated fee structure, pre-notification and route assessments for ultra-hazardous materials, and a civil forfeiture system with penalties of up to $10,000 for hazardous material and safety violations

Blood sampled from existing peripheral IV cannulae yields results equivalent to venepuncture: a systematic review

Objectives: To establish whether blood samples taken from used peripheral intravenous cannulae are clinically interchangeable with venepuncture. Design: Systematic review. PubMed, Web of Science and Embase were searched for relevant trials. Setting: Trials which compared blood samples from used peripheral intravenous cannulae to venepuncture and provided limits of agreement or data which allowed calculation of limits of agreement. Participants: Seven trials with 746 participants. Blood tests included 13 commonly ordered biochemistry, haematology and blood gas measurements. Main outcome measures: 95% limits of agreement. Data were pooled using inverse variance weighting and compared to a clinically acceptable range estimated by expert opinion from previous trials. Results: Limits of agreement for blood samples from used peripheral intravenous cannulae were within the clinically acceptable range for sodium, chloride, urea, creatinine and haematology samples. Limits of agreement for potassium were 0.47 mmol/L which exceeded the clinically acceptable range. Peripheral intravenous cannula samples for blood gas analysis gave limits of agreement which far exceeded the clinically acceptable range. Conclusions: Blood sampling from used peripheral intravenous cannulae is a reasonable clinical practice for haematology and biochemistry samples. Potassium samples from used peripheral intravenous cannulae can be used in situations where error up to 0.47 mmol/L is acceptable. Peripheral intravenous cannula samples should not be used for blood gas analysis

Coming Clean and Green: A Geospatial Mapping Tool for Visualizing Industrial Environmental Performance

The mapping of environmental data is rapidly expanding as advocates and scholars offer various platforms to display and analyze geographic environmental information.This working paper describes an online web map that displays national data from the Toxic Release Inventory (TRI), Environmental Systems Research Institute’s (ESRI) ArcGIS Server platform, the Environmental Protection Agency’s (EPA) Risk Screening Environmental Indicators (RSEI), and methodologies from Kraft, Stephan, and Abel (2011) to spatially display the environmental performance of more than 17,000 manufacturing facilities

Playing with numbers: Using Top Trumps as an ice-breaker and introduction to quantitative methods

Statistics anxiety has been widely documented among both postgraduate and undergraduate social science students and shown to be an obstacle in engaging students in quantitative methods. This article builds on previous studies that have highlighted the utility of fun and games in productive learning and overcoming anxiety. A personalised version of the game Top Trumps was developed for use with a class of postgraduate sociology students in the UK. This game provides an ideal way for students to inductively learn about basic statistical concepts, such as range and dispersion. The game also creates opportunities to engage students in critical discussion of measurement and social categorisation. The article suggests that the employment of such hands-on learning exercises, especially when used in the first week of a quantitative methods module, can stimulate student interest, ameliorate statistics anxiety and encourage critical discussion, thereby positively impacting learning goals in the rest of the module. The article ends by briefly outlining how to adapt the game for use within an undergraduate module

Ear, nose and throat manifestations of Lyme disease

The manifestations of Lyme disease as they may present to the ENT surgeon are discussed. The most important ENT symptom is facial palsy. Particularly when combined with other cranial palsies, systemic illness or signs of meningeal irritation, the diagnosis must be considered. Three case reports are used to illustrate the presentation and diagnosis and treatment of Lyme disease. The characteristics of the disease are reviewed and the limitations of serological testing outlined. The literature has concentrated on bilateral or relapsing facial palsy. A review of palsies in Zurich that presented to the ENT clinic found only unilateral and partial palsies. The diagnosis should be considered in every case of facial palsy of unknown aetiology especially in childre

Can owners afford humanitarian donations in Agbiotech- the case of genetically engineered eggplant in India

Are humanitarian donations in agbiotech economically feasible for the donor? We address this question by conducting an ex ante analysis of genetically engineered (GE) eggplant in India. Our analysis indicates that it is economically viable for a firm to donate the technology for poor farmers\u2019 use by restricting use to open pollinated varieties while selling hybrid verities. By extension, this means of segmenting markets would likely apply in cases where different levels of production technologies are used based on access to market, irrigation, and credit, at least for perishable crops

Mixed-Mode Surveys Compared with Single Mode Surveys: Trends in Responses and Methods to Improve Completion

This article reviews recent trends in modes of conducting surveys and presents results from a series of experiments comparing different approaches for collecting survey data and improving response rates in general population studies. The modes examined include the telephone, mail, and a mixed-mode method which combines mail with Web data collection. A series of studies were conducted by the Oregon State University Survey Research Center from 2006-2014 using probability samples of Oregon residents. Response rates and the percent of respondents completing the questionnaires by Web were compared. The results showed that response rates were increased by modifying the cover letter to emphasize the cost savings of an online response, adding a fifth contact, and limiting instructions for respondents. A mixed-mode approach, providing only a Web link, resulted in more respondents replying by Web as compared with individuals given an option of completing the questionnaire by Web or mail. The demographics of the respondents, as compared with the general population, varied across each mode
