Analysis of cloud-to-ground lightning and its relation with surface pollutants over Taipei, Taiwan

Premonsoon (March-April) cloud-to-ground (CG) lightning activity over Taipei, Taiwan, is analyzed in relation to surface pollutants like particulate matter (PM 10), sulfur dioxide (SO2), nitrogen oxides (NOx) and ozone (O3) con- centration for a period of 6 years (2005-2010). Other surface parameters like aerosol optical depth and cloud top temper- ature are also investigated taking data from Moderate Reso- lution Imaging Spectroradiometer satellite products. Results reveal that SO2 is more strongly associated with CG light- ning activity compared to PM10 concentration. Other surface pollutants like NOx and O3 also show strong linear asso- ciation with CG lightning flashes. Additional investigations have also been performed to extreme lightning events, par- ticularly to a few long-lasting lightning episodes considering the concentrations of NOx and O3 found on days with no lightning activity as representative of the background con- centration levels of the said two parameters. Results indicate that the NOx concentration on days with lightning activity is more than 2-fold compared to the non-lightning days while the O3 concentration is increased by 1.5-fold. Such increase in NOx and O3 concentration on days with lightning strongly supports the transport phenomena of NOx and O3 from the upper or middle troposphere to the lower troposphere by downdraft of the thunderstorm during its dissipation stage. Overall, studies suggest that enhanced surface pollution in a near-storm environment is strongly related to the increased lightning activity, which in turn increases the surface NO x level and surface O3 concentration over the area under study.
Which findings should be published?

Given a scarcity of journal space, what is the socially optimal rule for whether an empirical finding should be published? Suppose that the goal of publication is to inform the public about a policy-relevant state. Then journals should publish extreme results, meaning ones that move beliefs sufficiently. For specific objectives, the optimal rule can take the form of a one- or a two-sided test comparing a point estimate to the prior mean, with critical values deter- mined by a cost-benefit analysis. An explicit consideration of future studies may additionally justify the publication of precise null results. If one insists that standard inference remain valid, however, publication must not select on the study’s findings (but may select on the study’s design).
Using translation process research to explore the creation of subtitles: an eye-tracking study comparing professional and trainee subtitlers

Although translation process research (TPR) has become one of the most active fields in Translation Studies in the last 20 years, the process of subtitle creation has received little attention. This subtitling process research study adopts TPR methods to explore the production of interlingual subtitles. We conducted two experiments: Experiment 1 comparing professional subtitlers and subtitling trainees using the same subtitling tool, and Experiment 2 comparing two groups of professional subtitlers, each using a different subtitling programme. We collected data from eye tracking, screen recording, mouse clicks and keystroke logging, and post-experiment interviews. In Experiment 1, professionals and trainees exhibited different subtitling processes, with trainees following a highly structured sequence of viewing, spotting, translation and revision stages. Professionals were slightly faster, but text condensation levels were similar for both groups. In Experiment 2, the options offered by the subtitling tool significantly affected the process. Additionally, the age and experience were suggested as relevant factors influencing the task. Our findings confirm the suitability of using TPR methods to study the production of subtitles and set the grounds for further studies in the field of subtitling process research.
Eye-tracking as a tool in process-oriented reading test validation

The present paper addresses the continuous need for methodological reflection on how to validate inferences made on the basis of test scores. Validation is a process that requires many lines of evidence. In this article we discuss the potential of eye tracking methodology in process-oriented reading test validation. Methodological considerations are highlighted and special significance is placed on the importance of studying the first reading of a text as well as reading while answering questions about it. This point of view expands the traditional scope of eye-tracking methodology in reading research. We conducted a small-scale study in which 18 12-year olds read and answered questions about a multimodal text. In this study comprehension scores were related to allocation of visual attention in two conditions: (i) reading a text passage for the first time; and (ii) rereading of the text passage while answering questions about it.
Conducting experimental research in audiovisual translation (AVT) : a position paper

Experimental studies on AVT have grown incrementally over the past decade. This growing body of research has explored several aspects of AVT reception and production using behavioural measures such as eye tracking, as well as venturing into physiological measures such as electroencephalography (EEG), galvanic skin response, and heart rate. As a novel approach to the field of AVT, the experimental approach has borrowed heavily from other fields with established experimental traditions, such as psycholinguistics, psychology, and cognitive science. However, these methodologies are often not implemented with the same rigour as in the disciplines from which they were taken, making for highly eclectic and, at times, inconsistent practices. The absence of a common framework and best practice for experimental research in AVT poses significant risk in addition to the potential reputational damage. Some of the most important risks are: the duplication of efforts, studies that cannot be replicated due to a lack of methodological standardisation and rigour, and findings that are, at best, impossible to generalise from and, at worst, invalid. Given the growing body of work in AVT taking a quasi-experimental approach, it is time to consolidate our position and establish a common framework in order to ensure the integrity of our endeavours. This chapter analyses problems and discusses solutions specifically related to the multidisciplinary nature of experimental AVT research. In so doing, it aims to set the course for future experimental research in AVT, in order to gain credibility in the wider scientific community and contributes new insights to the fields from which AVT has been borrowing. Its conclusion lays out the foundation for a common core of measures and norms to regulate research in the growing field of AVT.
Continuous Refactoring in CI: A Preliminary Study on the Perceived Advantages and Barriers

By definition, the practice of Continuous Integration (CI) promotes continuous software quality improvement. In systems adopting such a practice, quality assurance is usually performed by using static and dynamic analysis tools (e.g., SonarQube) that compute overall metrics such as maintainability or reliability measures. Furthermore, developers usually define quality gates, i.e., source code quality thresholds that must be reached by the software product after every newly committed change. If certain quality gates fail (e.g., a maintainability metric is below a settled threshold), developers should refactor the code possibly addressing some of the proposed warnings. While previous research findings showed that refactoring is often not done in practice, it is still unclear whether and how the adoption of a CI philosophy has changed the way developers perceive and adopt refactoring. In this paper, we preliminarily study—running a survey study that involves 31 developers—how developers perform refactoring in CI, which needs they have and the barriers they face while continuously refactor source code.
Interactive comment on “ Global modelling of H 2 mixing ratios and isotopic compositions with the TM 5 model ”

The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their stable isotopic composition and isotope fractionation constants, into the global chemistry transport model TM5. For the first time, a global model now includes a simplified but explicit isotope reaction scheme for the photochemical production of H 2. We present a comparison of modelled results for the H 2 mixing ratio and isotope composition with available measurements on seasonal to inter annual time scales for the years 2001–2007. The base model results agree well with observations for H2 mixing ratios. ForδD[H2], modelled values are slightly lower than measurements. A detailed sensitivity study is performed to identify the most important parameters for modelling the isotopic composition of H 2. The results show that on the global scale, the discrepancy between model and measurements can be closed by adjusting the default values of the isotope effects in deposition, photochemistry and the stratosphere-troposphere exchange within the known range of uncertainty. However, the available isotope data do not provide sufficient information to uniquely constrain the global isotope budget. Therefore, additional studies focussing on the isotopic composition near the tropopause and on the isotope effects in the photochemistry and deposition are recommended. Correspondence to: T.

Maize Development: Cell Wall Changes in Leaves and Sheaths

Developmental changes occur in maize (Zea mays L.) as it transitions from juvenile stages to the mature plant. Changes also occur as newly formed cells mature into adult cells. Maize leaf blades including the midribs and sheaths undergo cell wall changes as cells transition to fully mature cell types. As is common in grasses during cell wall maturation, the lignin in the plant tissue is acylated with p-coumarates (pCA). This work characterizes cell walls in maize that make up leaf blade, leaf midrib, and sheath tissues corresponding to tissue development. Maize plants grown in the greenhouse were harvested; leaf, leaf midrib, and sheath tissues from nodes 9 through 14 tissues were analyzed for cell wall composition. Cell wall carbohydrates varied with the type of maize tissue, but there was little change within a tissue type among the different nodes. Lignin concentrations were lowest in the leaf blade (70 - 88 g·kg-1 CW) followed by the sheath (123 - 140 g·kg-1 CW) and highest in the midrib (140 - 168 g·kg-1 CW). Incorporation of pCA into cell walls paralleled the lignification. Ferulates (FA) remained relatively constant as a proportion of the cell wall (3.1 - 6.4 g·kg-1 CW) across nodes and across all tissue types. The range of FA was 3.8 vs 5.7 g·kg-1 CW averaged over all nodes with leaf blades being the lowest. Lignin composition did not change significantly with cell wall maturation within a given tissue type. The aerial portions of maize plants excluding the stem showed little difference in cell wall composition along the different nodes. Higher levels of ferulates were found in the sheath and leaf midrib compared to the leaf blade tissues. Leaf midribs from the upper nodes of the plant contained the highest levels of lignin. Perhaps a reflection of the function to keep leaves extended and in an upward angle to help maximize photosynthetic capacity.
Ion dynamics in electron beam-plasma interaction: particle-in-cell simulations

Abstract. Electron beam–plasma interaction including ions is studied by particle-in-cell (PIC) simulations using a one-dimensional, electrostatic code. Evidence for Langmuir wave decay is given for sufficiently energetic beams, as in previous Vlasov–Maxwell simulations. The mechanism for the generation of localized finite-amplitude ion density fluctuations is analyzed. Amplitude modulation due to interference between the beam-generated Langmuir waves causes random wave localization including strong transient spikes in field intensity which create bursty ion density structures via ponderomotive forces. More dense beams may quench the decay instability and generate low-frequency variations dominated by the wave number of the fastest growing Langmuir mode.
Uncertainty-based Online Mapping and Motion Planning for Marine Robotics Guidance

In real-world robotics, motion planning remains to be an open challenge. Not only robotic systems are required to move through unexplored environments, but also their manoeuvrability is constrained by their dynamics and often suffer from uncertainty. One approach to overcome this problem is to incrementally map the surroundings while, simultaneously, planning a safe and feasible path to a desired goal. This is especially critical in underwater environments, where autonomous vehicles must deal with both motion and environment uncertainties. In order to cope with these constraints, this work proposes an uncertainty-based framework for mapping and planning3 feasible motions online with probabilistic safety-guarantees. The proposed approach deals with the motion, probabilistic safety, and online computation constraints by (i) incrementally representing the environment as a collection of local maps, and (ii) iteratively (re)planning kinodynamically-feasible and probabilistically-safe paths to goal. The proposed framework is evaluated on the Sparus II, a nonholonomic torpedo-shaped AUV, by conducting simulated and real-world trials, thus proving the efficacy of the method and its suitability even for systems with limited on-board computational power.
Response of Seeds Quality of Sunflower to Inoculation with Single and Mixed Species of Indigenous Arbuscular Mycorrhizal Fungi

The sunflower seeds which are popular in Syria and Mediterranean countries as a roasted or salted snack, supply a large number of nutritious components including protein and minerals. A pot experiment was conducted to determine the impact of indigenous Arbuscular Mycorrhizal Fungi (AMF) on phosphorus (P), nitrogen (N), and protein content in seeds of confection-type hybrid sunflower (Helianthus annuus L.). The indigenous AMF including Glomus intraradices, Glomus mosseae, and Glomus viscosum, were isolated from an agricultural field in Syria. The most abundant species (G. viscosum) was multiplied in monospecific culture. Sunflower plants were inoculated with the mixture of three AMF species or with G. viscosum. The plants were harvested at full physiological maturity stage. Total N was determined using the Kjeldhal method and the detection of phosphorus was based on the colorimetric method. The rate of AMF-root colonization was determined microscopically by the gridline intersect method. Seeds N and P content were enhanced by the inoculation of sunflower with single and mixture of AMF compared with non-AM plants. Higher content of N and P was observed in AMF mixture inoculation compared to individual inoculation with G. viscosum. The maximum protein concentration was found in the treatment of mixture AMF followed by individual inoculation with G. viscosum. The results indicated that mixed species of AMF were more species, and could be considered as a good inoculum for improving the seeds quality of sunflower grown under sustainable agriculture conditions.
Factors in Pulmonary Embolus Diagnosis via CT Pulmonary Angiogram in Patients Undergoing Repair of Proximal Femur Fractures

Background: As imaging technology improves small Pulmonary Emboli (PE) of debatable clinical relevance are increasingly detected leading to higher numbers of patients receiving anticoagulation. Although PE are an important cause of morbidity and mortality in patients undergoing repair of proximal femur fractures, this cohort of patients are at increased falls risk and are therefore largely unsuitable for long term anticoagulant therapy. Objective: 1. To review sequential Computed Tomography Pulmonary Angiograms (CTPA) performed in patients who underwent repair of proximal femur fractures at our institution. 2. To establish the perioperative CT imaging performed. Design: A retrospective cross sectional study of all patients undergoing proximal femur fracture repair at a single tertiary referral. Methods: The theatre database was interrogated to reveal all patients undergoing proximal femur fracture repair over a 28 month period from 01/01/12 to 07/04/14 inclusive. This was cross-referenced with the Picture Archiving Communication System (PACS) to establish all imaging undertaken in the perioperative period. CTPA studies performed within the time period of 1 week prior to and 6 months post proximal femur fixation were included. CTPA studies and reports were assessed for quality and findings. D-Dimer results, if performed within 72 hours of the CTPA study, were recorded. Results: 1388 patients underwent neck of femur fracture repair in the 28-month study period. Of this cohort 71 CTPA studies were performed in 71 patients (5.2%) with a mean age of 77.8 years (range 38 - 100). 53 (74.6%) of studies were negative for embolus and 17 (23.9%) studies revealed clot in a pulmonary artery (1 saddle embolus, 2 main pulmonary artery emboli, 7 lobar vessel emboli, 2 segmental artery emboli, 5 subsegmental emboli). Overall PE detection rate was 1.2% of our total study population. In all 71 studies, Houndsfield Unit (HU) in the main pulmonary artery (PA) was >200; which is considered to be of satisfactory quality to assess for segmental pulmonary emboli. 32% of patients had D Dimer levels performed, however no relationship with presence of PE on CTPA was demonstrated. Conclusion: The rate of positive CTPA studies in patients undergoing proximal femur fracture repair is 23.9% in our patient population, comparing favorably to published data. This is likely to reflect good compliance with prevention measures at ward level. D-Dimer results are unreliable for PE prediction.
Do Better Political Institutions Help in Reducing Political Pressure on State-Owned Banks? Evidence from Developing Countries

This study examines whether state-owned banks face political pressure and whether the improvement in political institutions alleviates this pressure. The theory of political benefits argues that politicians use state-owned banks for political purposes such as obtaining and maintaining political support. We reviewed extant empirical research and found that the existing evidence is mixed; some studies support while others reject the theory. In this backdrop, we analyzed a sample of 185 state-owned banks from 51 developing countries over the period 1998–2012 and provide renewed evidence supporting the theory. Specifically, we found that state-owned banks face significant political pressure in developing countries; that is, they lend more and earn less in election years. Next, we observed that the political pressure is prevalent only in the countries with weak political institutions. Strong political institutions in the form of higher constraints on policy change decisions of incumbent government and higher democratic accountability are helpful in eliminating political pressure on state-owned banks in developing countries.
The Role of the Eleven-Plus Test Papers and Appeals in Producing Social Inequalities in Access to Grammar Schools

We use eleven-plus test and appeals data obtained from a large local authority to explore how the process of admission to grammar schools produces such a strong social gradient in entry rates. We look at disparities between eleven-plus and subsequent SATs scores by social background for each element of the test. We then turn to whether the headteacher assessment panel seems to help or hinder poor students on the cusp of passing. Our analysis has implications for how to improve access to grammar schools for those from disadvantaged families.
Biomarkers and Gene Polymorphisms in Members of Long- and Short-lived Families: A Longevity Study

Background: The influence of biomarkers in human lifespan has been investigated but with no clear results yet. Materials and methods: Lipids, Uric Acid (UA), Adiponectin (ADIPOQ), Insulin-like Growth Factor (IGF-1), cholesteryl ester transfer protein (CETP) and angiotensin-converting enzyme (ACE) proteins, as well as CETP, ADIPOQ, insulin-like growth factor binding protein-3 (IGFBP3) and ACE-gene polymorphisms were evaluated in 149 Greek individuals. The Long-Lived Families (LON) (n=84) comprised of 3 generations: long-lived aged ≥90 years (P), offspring (FL1) and their grandchildren (FL2), while the Short-Lived Families (EAD) (n=65) where both parents died <75 years, comprised of 2 generations: middle-aged (FD1) and children (FD2). Results: Serum CETP and IGF-1 levels were lower, whereas AdipoQ concentrations were higher in P compared with FL1 and FL2 members (CETP: p = 0.03 for both comparisons; IGF-1 p < 0.001 for both comparisons and ADIPOQ: p = 0.001 and p = 0.004, respectively). Furthermore, serum triglycerides, UA and glucose concentrations were higher in FD1 compared with FD2 subjects (p=0.001, 0.02 and ≤0.001, respectively). In FD2 and FL2, CETP levels were lower in individuals with B2B2 compared with B1B1 genotype (p=0.007). Additionally, ACE concentrations were higher in individuals with DD compared with II genotype in both Families (p=0.001). After adjustment for age and gender, CETP levels were lower in P and FL2 individuals with B2B2 compared with the B1B1 genotype (p=0.004 and 0.007, respectively). Conclusion: Increase serum TGs, UA and GL concentrations were higher in the middle-aged individuals compared with their children in families independently of their lifespan. The serum adiponectin concentration was the highest in the oldest old individuals implying beneficial influence on lifespan. Independently of family’s lifespan history, the youngest individuals with CETPB2B2 genotype, compared with individuals with CETPB1B1 genotypes, had lower serum CETP concentrations. The knowledge of the unfavourable gene(s)influencing human lifespan may be helpful in encouraging individuals to follow healthier lifestyle habits and better control their high-risk biomarkers.
Is it Possible to Recover Cardiac Functions After Total Knee Arthroplasty?

Background: Patients suffering from knee osteoarthritis lead a less active life than their healthy peers. It is well known that insufficient physical activity is the most common cause of chronic diseases. However, there is not enough research to enlighten the effect of increased functional capacity on cardiac functions after Total Knee Arthroplasty (TKA). This study aimed to investigate whether the orthopedic surgeons can predict that the patients will be healthier after TKA in terms of cardiac functions or not? Methods: 109 patients who underwent TKA were prospectively followed for one year. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and short form 36 (SF-36) surveys, BMI measures, average step count per day, the six-minute walking test (6MWT), the Five-Times-Sit-to-Stand Test (FTSST) and Doppler echocardiography were performed both in the preoperative and postoperative period. Results: After TKA, there was a substantial improvement in terms of WOMAC and SF36 survey scores. The average step count increased from 2199.6±690.8 steps/day to 4124.3±1638.8 steps/day. 6MWT and FTSST improved significantly as well. The average brisk walking time was 174.23±95.11 minutes/week. The means of early and late mitral inflow velocity ratios (E/A and Em/Am ratios) increased from 0.71±0.12 to 0.77±0.13 and from 0.66±0.13 to 0.76± 0.15 at the first year follow-up visit, respectively (p<0.001). Conclusion: In the first year, objective physical capacity measures increased together with the expected improvements in disease-specific and generic measures. After TKA, left ventricular diastolic functions may be considered to have recovered in the light of the healing signs via echocardiography.
