Widespread persistent near‐surface ozone depletion at northern high latitudes in spring

Springtime near‐surface ozone depletion has been observed at northern high latitudes. Due to limited observations, the spatial and temporal extent of low O3 concentrations near the surface is still unknown. A regional 3‐D chemistry and transport model is applied to simulate surface O3 depletion catalyzed by bromine radicals at northern high latitudes in March and April 2000. Satellite observations of BrO column by the ESA Global Ozone Monitoring Experiment (GOME) were processed to specify the BrO concentrations in the lower troposphere. In view of the GOME measurement and model uncertainties, the model results show an adequate agreement with the O3 depletion events observed at two surface sites, Alert, Canada (82.5°N, 62.3°W) and Barrow, Alaska (71.3°N, 156.6°W), and by airborne in situ and DIAL instrument during the TOPSE experiments at northern high latitudes. Low O3 events at Alert appear to be mostly driven by transport of O3‐poor air from high BrO regions. Model results indicate that low O3 concentrations (<20 ppbv) near the surface cover ∼60% of the northern high latitudes and that the depleted O3 concentrations (<10 ppbv) cover ∼20% of the region in April. The high BrO events tend to be large‐scale and persistent (1–2 weeks). We find that they are correlated with low temperature, a condition conducive for heterogeneous reactions on frozen snow or aerosol surfaces.
Review of the Progress and Process of Satellite Imagery and Road Databases Conflation

Spatial data conflation plays a fundamental role in in many aspects of modern Geographic Information Systems (GIS) research and development such as geospatial data visualization, incremental updating of databases and disaster evaluation. The primary objective of conflation is to derive valuable information based on the comparison of multiple spatial data sources of homogeneous or heterogeneous nature. This paper reviews the state of art of the concept of conflation, feature matching, the most important progresses of conflation between image and road network data, and the complexity of spatial conflation.
An Investigation into the Impact of Absenteeism on the Organisational Performance of a Private Security Company in Durban , Kwazulu-Natal

In the increasingly competitive and challenging environment within which organisations operate today, absenteeism is a complex issue. Resulting from absenteeism, businesses are faced with impeded productivity, inefficient service delivery, and reduced performance, thereby negatively affecting sustainability. Absenteeism is, therefore, a significant concern in the field of human resource management. The prevalence of absenteeism in the security sector necessitates investigation so that valuable contributions may be made that will, ultimately, empower management and positively contribute to the discipline being studied. The aim of this study was to investigate the impact of absenteeism and the extent to which it negatively affects organisational performance. For the purpose of this study, a quantitative research approach was employed. The total population of forty-five respondents was targeted, with a 95% response rate achieved. A questionnaire was utilised to gather data from the target population.
Influence of the aspS Gene Sequence from Acetobacter pasteurianus SKU 1108 on 1 Escherichia coli Morphology 2 3

Abstract: The aspS gene encoding Aspartyl-tRNA synthetase (AspRS) from a thermotolerant acetic acid bacterium, Acetobacter pasteurianus SKU1108, has been cloned and characterized. The open reading frame (ORF) of aspS gene consists of 1,788 bp and coding 595 amino acid residues. The highly conserved of Gly-Val-Asp-Arg (motif 3), the ATP binding motif, is located at the position 537-540 in the C-terminus. Deletion analysis of the aspS gene upstream region suggested that the tentative promoter is around 173 bp upstream from ATG initiation codon. Interestingly, transformation with the plasmid pGEM-T138, pUC138 and pCM138 synthesizing 138 amino acids of Cterminal fragments of AspRS harboring the ATP binding domain caused E. coli cell lengthening at 37 and 42 ̊C. Moreover, E. coli harboring pUC595 (synthesizing 595 amino acids) and disordered aspS gene in pGEM-T138 had normal rod shapes. The normal rod shape was observed in E. coli harboring pD539V following site-directed mutagenesis of the ATP binding domain. We propose that over-production of truncated C-terminal sequence of aspS may cause sequestration of intracellular ATP of E. coli leaving less ATP for cell division or shaping cell morphology.
Municipal Waste Selection and Disposal: Evidences from Lombardy

This article exploit a data base of 1.522 observations related to Lombardy’s municipalities to run a cross sectional estimation of the drivers of MW selection. We find no evidence of a significant correlation between the percentage of selected MW selection and market variables such as the unit charge for waste management, a result probably affected by the high degree of integration existing in Lombardy among collectors and disposal operators. On the contrary, we discover robust and significant correlation with a set of geographical, socio-economic, and political variables. Among the latter ones, we have a confirmations on the influence of party competition on the percentage of household recycling, with the left wing ruling parties more addressed to it than the rivals, and on the high correlation existing between MW selection and the implementation of a unit pricing scheme. Other positive correlations with the independent variable are shown by per-capita income, while quite surprisingly the education level of citizens seems to play no role.
Construction of intergeneric conjugal transfer for molecular genetic studies of Streptomyces mobaraensis producing transglutaminase

To facilitate molecular studies of Streptomyces mobaraensis producing transglutaminase, an effective transformation method was established via intergeneric conjugal transfer using Escherichia coli ET12567 harboring the OC31-derived integration vector, pSET152. The highest frequency was attained on ISP4 medium containing 20 mM MgCl 2 , using 2.5 × 10 8 E. coli as donor and spore treated with heat treatment at 35°C for 10 min as host. The attB integration site in the S. mobaraensis genome was detected as a single attB site within an open reading frame coding for a pirin homolog. Its sequence showed the highest degree of homology with S. aureofaciens .

On the Consistent Migration of Splittable Flows: Latency-Awareness and Complexities

Network traffic demands change all the time, giving rise to the well-investigated topic of consistent network updates. We in this paper study the consistent migration of flows, in particular the avoidance of transient congestion. Most previous work implemented rather coarse-grained techniques, ignoring the effect of link latency in their computations. Recent work shows that, in order to achieve the goal of zero packet loss, earlier methods need to be adapted to cope with link latency. However, the current work only considers unsplittable flows, which are routed along a single path. We present the first study of splittable flows in this context, where a single flow may be spread over the network for better throughput and load balancing. Interestingly, splittable flows seem to be harder to tackle in this setting from a complexity point of view. Nonetheless, we provide the first methods and insights to integrate splittable flows into consistent update frameworks under the aspect of link latencies.
Plasma transport in stochastic magnetic field caused by vacuum resonant magnetic perturbations at diverted tokamak edge

A kinetic transport simulation for the first 4 ms of the vacuum resonant magnetic perturbations (RMPs) application has been performed for the first time in realistic diverted DIII-D tokamak geometry [J. Luxon, Nucl. Fusion 42, 614 (2002)], with the self-consistent evaluation of the radial electric field and the plasma rotation. It is found that, due to the kinetic effects, the stochastic parallel thermal transport is significantly reduced when compared to the standard analytic model [A. B. Rechester and M. N. Rosenbluth, Phys. Rev. Lett. 40, 38 (1978)] and the nonaxisymmetric perpendicular radial particle transport is significantly enhanced from the axisymmetric level. These trends agree with recent experimental result trends [T. E. Evans, R. A. Moyer, K. H. Burrell et al., Nat. Phys. 2, 419 (2006)]. It is also found, as a side product, that an artificial local reduction of the vacuum RMP fields in the vicinity of the magnetic separatrix can bring the kinetic simulation results to a more detailed agreement with experimental plasma profiles.
A true test: do IMF programs hurt the poor?

This article analyses the effect of IMF programs on poverty with data from 82 countries during 1985–2000. Two indicators of poverty, infant mortality rates and the human development index (HDI), are utilized, and the effects of the IMF's concessionary and nonconcessionary programs are investigated, as well as economic and institutional factors. The results show that the IMF's programs have no significant direct impact on poverty. Growth and good institutions, however, both have significant impacts, lowering infant mortality and increasing the HDI. The Fund's concessionary programs increase the impact of growth on lowering infant mortality, while the nonconcessionary programs lower the impact of growth on the HDI. “Where a great proportion of the people are suffered to languish in helpless misery, that country must be ill policed, and wretchedly governed; a decent provision for the poor is the true test of civilization. ” –Samuel Johnson, 1791 “… once a country was in crisis, IMF funds and programs not only failed to stabilize the situation but in many cases actually made things worse, especially for the poor. ” –Joseph Stiglitz, 2002
Aalborg Universitet Worst-Case Traversal Time Modelling of Ethernet based In-Car Networks using Real Time

The paper addresses performance modelling of safety critical Ethernet networks with special attention to in-car networks. A specific Ethernet/IP based in-car network is considered as use-case. The modelling is based on the analytical method Real-Time Calculus (RTC), providing hard bounds on delay and buffer utilization. We show how RTC can be applied on the use-case network. Furthermore, we develop a network simulation, used to evaluate the overestimation. It is found that the delays from RTC is significantly overestimated. The bounds from RTC, however, are guaranteed bounds, which is not the case for the simulated. Real-Time Calculus, Vehicular Networks, Performance Modelling, Ethernet Modelling, Delay Bounds.
Preliminary photochemical studies of fluorene in various aqueous media

The current study investigates the direct photochemical degradation of aqueous fluorene with the aid of a 125W polychromatic medium, pressure Hg lamp. The purpose was to test the effectiveness of the lamp in irradiation using fluorene spiked solution as substrate. A 700 ml volume of fluorene solution of 0.002 mg/l was irradiated batch-wise at 1, 3, 6, 12, 18, 24 and 48 h. The amount of fluorene removal was studied for fluorene solutions prepared from , neutral (distilled water), acidic (by adjusting pH with hydrochloric acid, HCl), basic (by adjusting pH with sodium hydroxide, NaOH) and saline (addition of sodium chloride, NaCl) solutions and there was 95.95, 92.35, 96.65 and 97.15 % removal respectively after 48 h of irradiation. The major degradation product identified was fluorenone. The different media did not significantly affect the rate of fluorene degradation.
Theoretical Overview of Basic Image Edge Detectors

Through the application of edge detection procedures to an image, the amount of data to be processed can be considerably reduced by filtering out and discarding information that are of less significance, and retaining the essential structural properties of the image. There are several techniques for detecting and processing image edge. The choice of any method relies on need of the end application. In some cases more than one technique is required to meet a targeted image processing output. The purpose of this paper is to comparatively introduce the basic edge detection methodologies by making analysis of their respective concepts and observing their tradeoffs in some conditions so that decision making criteria are established for guidance in application developments.
Toward radical polymer batteries : strategies , mechanism and perspectives

This chapter gives a comprehensive overview of the recent advancement in the emerging field of radical polymer batteries, also named as organic radical batteries. The rationale behind the use of a polymer with stable radicals as an electrodeactive material of a secondary battery lies in the fact that this type of radical polymer has powerful capability of rapid oxidization to a cation and reverse reduction to an anion during the charge/discharge process. Radical polymer batteries promise as the replacement for lithium-ion battery, due to its intriguing features of extremely rapid charge/discharge rate, low toxicity, long lifecycle, cost-effectiveness, and high performance. Thus far, through molecular design, a couple of strategies have been applied to afford radical polymers with high discharge capacity. Because of their high flexibility and lightweight, the dream of paper-like transparent battery would become true if both cathode and anode employ radical polymers. This chapter focuses on elaborating on the strategies toward this new type of battery, its underlying mechanism, composite electrodes, cell device fabrication, and future opportunities and challenges.
IMAGE RECOGNITION BASED ON SIMILARITY OF CURVE CHARACTERISTICS INVARIANT TO TRANSLATION

Objects similarity are required in image recognition, such as in quality control problems. Characteristics of objects in an image are represented by the characteristics of the detected edges. Curve is one of the detected edge beside point, line, and region. Curve provides geometric and structural information of the image. It gives better information than point. The existing research related to the similarity of curve characteristic are still facing problems associated with invariant to geometric transformations. Therefore, this research discusses how to use the characteristics of curve, so that the curve similarity can be invariant to translation. In using the characteristics of curve, the first step is curves tracking using 8 (eight) directions chain codes. Furthermore, the algorithms to determine the type of curve and to determine the similarity between curves which invariant to translation are explained. The definition of curve itself was used in determining the types of curves. The similarity of curves is determined based on the characteristics of curves. This proposed image recognition algorithm can detect similar image while geometric translation is occurred.
TAPAS: Generating Parallel Accelerators from Parallel Programs

High-level-synthesis (HLS) tools generate accelerators from software programs to ease the task of building hardware. Unfortunately, current HLS tools have limited support for concurrency, which impacts the speedup achievable with the generated accelerator. Current approaches only target fixed static patterns (e.g., pipeline, data-parallel kernels). This constraints the ability of software programmers to express concurrency. Moreover, the generated accelerator loses a key benefit of parallel hardware, dynamic asynchrony, and the potential to hide long latency and cache misses. We have developed TAPAS, an HLS toolchain for generating parallel accelerators from programs with dynamic parallelism. TAPAS is built on top of Tapir [22], [39], which embeds fork-join parallelism into the compiler's intermediate-representation. TAPAS leverages the compiler IR to identify parallelism and synthesizes the hardware logic. TAPAS provides first-class architecture support for spawning, coordinating and synchronizing tasks during accelerator execution. We demonstrate TAPAS can generate accelerators for concurrent programs with heterogeneous, nested and recursive parallelism. Our evaluation on Intel-Altera DE1-SoC and Arria-10 boards demonstrates that TAPAS generated accelerators achieve 20× the power efficiency of an Intel Xeon, while maintaining comparable performance. We also show that TAPAS enables lightweight tasks that can be spawned in '10 cycles and enables accelerators to exploit available fine-grain parallelism. TAPAS is a complete HLS toolchain for synthesizing parallel programs to accelerators and is open-sourced.
Transforming Some Stabilizer Codes into Hybrid Codes

In this paper, we prove how to extend a subset of quantum stabilizer codes into a qudit hybrid code storing $\log_2 p$ classical bits over a qudit space with dimension $p$, with $p$ prime. Our proof also gives an explicit procedure for finding the entire collection of stabilizer algebras for all of the subcodes of the hybrid code. This allows extra classical information to be transmitted without having to arduously search for additional codes and their associated codewords, and also provides a first lower bound to the amount of classical information able to be transmitted in a qudit hybrid code, but unfortunately only allows for $\log_2 p$ classical bits to be decoded by a receiver.
Experimental investigation of interface states and photovoltaic effects on the scanning capacitance microscopy measurement for p-n junction dopant profiling

Controlled polishing procedures were used to produce both uniformly doped and p‐n junction silicon samples with different interface state densities but identical oxide thicknesses. Using these samples, the effects of interface states on scanning capacitance microscopy (SCM) measurements could be singled out. SCM measurements on the junction samples were performed with and without illumination from the atomic force microscopy laser. Both the interface charges and the illumination were seen to affect the SCM signal near p‐n junctions significantly. SCM p‐n junction dopant profiling can be achieved by avoiding or correctly modeling these two factors in the experiment and in the simulation.

Geodetic observations of postseismic creep in the decade after the 1999 Izmit earthquake, Turkey: Implications for a shallow slip deficit

The relationship between aseismic slip and tectonic loading is important for understanding both the pattern of strain accumulation along a fault and its ability to generate large earthquakes. We investigate the spatial distribution and temporal evolution of aseismic creep on the western North Anatolian Fault (NAF) using time series analysis of Envisat interferometric synthetic aperture radar (InSAR) data, covering the full extent of the 1999 Izmit and Düzce earthquake ruptures and spanning 2002–2010. Discontinuities in the line‐of‐sight velocity across the fault imply that fault creep reaches the Earth's surface at an average fault‐parallel rate of ∼5 mm/yr along an ∼80 km section of the NAF. By combining InSAR and published GPS velocities, we are able to extract the vertical and east‐west components of motion and show that the Adapazari basin is subsiding at a rate of ∼6 mm/yr. Vertical motions have biased previous estimates of creep in this region. The displacement time series close to the fault is consistent with an afterslip model based on rate‐and‐state friction, which predicts a rapid deceleration in fault creep rate after the Izmit earthquake to a near‐steady state ∼5 mm/yr after 5 years. Projecting our model 200 years into the future we find that the cumulative displacement of 1–1.3 m is insufficient to account for the shallow coseismic slip deficit observed in previous studies. Distributed off‐fault deformation in the shallow crust or transient episodes of faster slip are likely required to release some of the long‐term strain during the earthquake cycle.
Implicit Regulation of Emotion: Priming Non-Conscious Reappraisal and Suppression During Stress

IMPLICIT REGULATION OF EMOTION: PRIMING NON-CONSCIOUS REAPPRAISAL AND SUPPRESSION DURING STRESS Sydney Timmer-Murillo Marquette University, 2017 As individuals experience the world, they must also appropriately modulate their responses to fit their environment. The manner in which one regulates their emotion can vary greatly and influence a number of factors, including self-reported affect and respiratory sinus arrhythmia (RSA). The majority of research on emotion regulation examines the deliberate, or explicit, regulation of emotion. However, the automatic or implicit regulation of emotion is an important cognitive process that yields several benefits. Recent research demonstrates benefits of using implicit reappraisal; however, no work has been done to examine other implicit strategies. The current study primed implicit reappraisal and suppression prior to two rounds of a distressing math task. Participants (N = 65) rated subjective emotional experience and RSA was recorded at three time points. Results demonstrated a main effect of time for affect, such that affect deteriorated over time. RSA significantly increased during the first round but decreased during the second round of the math task compared to baseline. No significant differences by condition were observed, possibly indicative of comparable implicit regulatory responses by both groups when called to regulate during a lengthy and arduous task. Therefore, more work is needed to examine if various strategies can be primed implicitly, depending on context, and how they may influence functioning.
Why Is Maximum Clique Often Easy in Practice?

To this day, the maximum clique problem remains a computationally challenging problem. Indeed, despite researchers’ best efforts, there exist unsolved benchmark instances with one thousand vertices. However, relatively simple algorithms solve real-life instances with millions of vertices in a few seconds. Why is this the case? Why is the problem apparently so easy in many naturally occurring networks? In this paper, we provide an explanation. First, we observe that the graph’s clique number ω is very near to the graph’s degeneracy d in most real-life instances. This observation motivates a main contribution of this paper, which is an algorithm for the maximum clique problem that runs in time polynomial in the size of the graph, but exponential in the gap g := (d+ 1)− ω between the clique number ω and its degeneracy-based upper bound d + 1. When this gap g can be treated as a constant, as is often the case for real-life graphs, the proposed algorithm runs in time O(dm) = O(m). This provides a rigorous explanation for the apparent easiness of these instances despite the intractability of the problem in the worst case. Further, our implementation of the proposed algorithm is actually practical—competitive with the best approaches from the literature.
