Coherence of long-term stratospheric ozone vertical distribution time series used for the study of ozone recovery at a northern mid-latitude station

Abstract. The coherence of stratospheric ozone time series retrieved from various observational records is investigated at Haute-Provence Observatory (OHP–43.93° N, 5.71° E). The analysis is accomplished through the intercomparison of collocated ozone measurements of Light Detection and Ranging (lidar) with Solar Backscatter UltraViolet(/2) (SBUV(/2)), Stratospheric Aerosol and Gas Experiment II (SAGE~II), Halogen Occultation Experiment (HALOE), Microwave Limb Sounder (MLS) on Upper Atmosphere Research Satellite (UARS) and Aura and Global Ozone Monitoring by Occultation of Stars (GOMOS) satellite observations as well as with in situ ozonesondes and ground-based Umkehr measurements performed at OHP. A detailed statistical study of the relative differences of ozone observations over the whole stratosphere is performed to detect any specific drift in the data. On average, all instruments show their best agreement with lidar at 20–40 km, where deviations are within ±5 %. Discrepancies are somewhat higher below 20 and above 40 km. The agreement with SAGE II data is remarkable since average differences are within ±1 % at 17–41 km. In contrast, Umkehr data underestimate systematically the lidar measurements in the whole stratosphere with a near zero bias at 16–8 hPa (~30 km). Drifts are estimated using simple linear regression for the data sets analysed in this study, from the monthly averaged difference time series. The derived values are less than ±0.5 % yr−1 in the 20–40 km altitude range and most drifts are not significant at the 2σ level. We also discuss the possibilities of extending the SAGE II and HALOE data with the GOMOS and Aura MLS data in consideration with relative offsets and drifts since the combination of such data sets are likely to be used for the study of stratospheric ozone recovery in the future.
Temperature-dependent exchange stiffness and domain wall width in Co

The micromagnetic exchange stiffness is a critical parameter in numerical modeling of magnetization dynamics and reversal processes, yet the current literature reports a wide range of values even for such simple and widely used material as cobalt. Using the ab initio estimated Heisenberg parameters we calculate the low temperature micromagnetic exchange stiffness for hexagonal-close-packed (hcp) and face-centered-cubic cobalt. For hcp Co they are slightly different in the directions parallel and perpendicular to the c axis. We establish the exchange stiffness scaling relation with magnetization A(m)∼m1.8 valid for a wide range of temperatures. For hcp Co we find an anisotropic domain wall width in the range 24-29 nm which increases with temperature. The results form a critical input for large-scale temperature-dependent micromagnetics simulations and demonstrate the importance of correct parametrization for accurate simulation of magnetization dynamics.
Spectral Evidence for Pseudogap Formation in Kondo Insulators CeRhAs and CeRhSb

High-resolution photoemission spectroscopy has been performed on CeRhAs and CeRhSb to study the temperature-induced evolution of the “Kondo-insulator” gap. We have observed that a pseudogap opens at EF at low temperatures while it is gradually filled with increasing temperature. The size of the pseudogap is well scaled with the Kondo temperature sTK d of each compound while the temperature evolution is dominated by another characteristic temperature Tcoh s, TK d. The results are qualitatively consistent with the theoretical prediction from the Anderson lattice model. [S0031-9007(99)08535-X]

Preliminary experiments show significant improvements over the original page-rank algorithm.
Hot Jupiters with relatives: discovery of additional planets in orbit around WASP-41 and WASP-47

We report the discovery of two additional planetary companions to WASP-41 and WASP-47. WASP-41 c is a planet of minimum mass 3.18 $\pm$ 0.20 M$_{\rm Jup}$ and eccentricity 0.29 $\pm$ 0.02, and it orbits in 421 $\pm$ 2 days. WASP-47 c is a planet of minimum mass 1.24 $\pm$ 0.22 M$_{\rm Jup}$ and eccentricity 0.13 $\pm$ 0.10, and it orbits in 572 $\pm$ 7 days. Unlike most of the planetary systems that include a hot Jupiter, these two systems with a hot Jupiter have a long-period planet located at only $\sim$1 au from their host star. WASP-41 is a rather young star known to be chromospherically active. To differentiate its magnetic cycle from the radial velocity effect induced by the second planet, we used the emission in the H$\alpha$ line and find this indicator well suited to detecting the stellar activity pattern and the magnetic cycle. The analysis of the Rossiter-McLaughlin effect induced by WASP-41 b suggests that the planet could be misaligned, though an aligned orbit cannot be excluded. WASP-47 has recently been found to host two additional transiting super Earths. With such an unprecedented architecture, the WASP-47 system will be very important for understanding planetary migration.
Strain and Dispersion Dependence of High Frequency Electromagnetic Properties of Carbon Nanotube/Epoxy Nanocomposites

An experimental setup and data reduction method has been developed for noninvasive high frequency electromagnetic impedance measurements of carbon nanotube (CNT)/epoxy nanocomposites. Using time domain reflectometry and parallel plate transmission lines, dielectric properties can be measured with the specimen under tensile loading. Good dispersion and addition of CNTs lead to an increase in high frequency dielectric constant of the nanocomposites. A strong strain dependence of the impedance is observed for the well dispersed nanocomposite while the baseline epoxy showed no strain dependence. A mechanism, based on an increase in CNT-CNT tunneling capacitance with applied tensile strain has been suggested. This research is expected to introduce a noninvasive characterization technique for studying electromagnetic properties of conductive nanocomposites.
IMPLEMENTING DYNAMIC CONFIGURATION TO IMPROVE THE QUALITY OF SERVICES IN CLOUD COMPUTING

I am to present the dynamic Configuration and dynamic linking of a Cloud. Day by day tremendous increase of users and usage has raised a question to the security of Cloud. Dynamic Configuration is a technique which increases the security by providing various server addresses and linking the request of the client to each Cloud. This increases the speed as well as security. My research introduced a new technique of configuration and setting up a Cloud. I have used the concept of dynamic IP Address while linking the Clients request to the server. The Entire configuration and setting is done on private Cloud . There are various levels of network protocol in the private cloud considered in our research.
Jellyfish, Forage Fish, and the World’s Major Fisheries

A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap in space, time, and diet in coastal ecosystems. This overlap likely leads to predatory and competitive interactions, as jellyfish are effective predators of fish early life stages and zooplankton. The trophic interplay between these groups is made more complex by the harvest of forage fish, which presumably releases jellyfish from competition and is hypothesized to lead to an increase in their production. To understand the role forage fish and jellyfish play as alternate energy transfer pathways in coastal ecosystems, we explore how functional group productivity is altered in three oceanographically distinct ecosystems when jellyfish are abundant and when fish harvest rates are reduced using ecosystem modeling. We propose that ecosystem-based fishery management approaches to forage fish stocks include the use of jellyfish as an independent, empirical “ecosystem health” indicator. DEDICATION. This paper is dedicated to our beloved friend and colleague, Hermes Mianzan, for his innumerable contributions to fisheries, zooplankton, and gelatinous zooplankton ecology. By Kelly L.

THE ORBIT AND MASS OF THE THIRD PLANET IN THE KEPLER-56 SYSTEM

While the vast majority of multiple-planet systems have orbital angular momentum axes that align with the spin axis of their host star, Kepler-56 is an exception: its two transiting planets are coplanar yet misaligned by at least 40° with respect to the rotation axis of their host star. Additional follow-up observations of Kepler-56 suggest the presence of a massive, non-transiting companion that may help explain this misalignment. We model the transit data along with Keck/HIRES and HARPS-N radial velocity data to update the masses of the two transiting planets and infer the physical properties of the third, non-transiting planet. We employ a Markov Chain Monte Carlo sampler to calculate the best-fitting orbital parameters and their uncertainties for each planet. We find the outer planet has a period of 1002 ± 5 days and minimum mass of 5.61 ± 0.38 M Jup . We also place a 95% upper limit of 0.80 m s−1 yr−1 on long-term trends caused by additional, more distant companions.
Graphical structures for design and verification of quantum error correction

We introduce a high-level graphical framework for designing and analysing quantum error correcting codes, centred on what we term the coherent parity check (CPC). The graphical formulation is based on the diagrammatic tools of the ZX-calculus of quantum observables. The resulting framework leads to a construction for stabilizer codes that allows us to design and verify a broad range of quantum codes based on classical ones, and that gives a means of discovering large classes of codes using both analytical and numerical methods. We focus in particular on the smaller codes that will be the first used by near-term devices. We show how CSS codes form a subset of CPC codes and, more generally, how to compute stabilizers for a CPC code. As an explicit example of this framework, we give a method for turning almost any pair of classical [n,k,3] codes into a [[2n−k+2,k,3]] CPC code. Further, we give a simple technique for machine search which yields thousands of potential codes, and demonstrate its operation for distance 3 and 5 codes. Finally, we use the graphical tools to demonstrate how Clifford computation can be performed within CPC codes. As our framework gives a new tool for constructing small- to medium-sized codes with relatively high code rates, it provides a new source for codes that could be suitable for emerging devices, while its ZX-calculus foundations enable natural integration of error correction with graphical compiler toolchains. It also provides a powerful framework for reasoning about all stabilizer quantum error correction codes of any size.
Some almost sure results for unbounded functions of intermittent maps and their associated Markov chains

We consider a large class of piecewise expanding maps T of [0,1] with a neutral fixed point, and their associated Markov chains Yi whose transition kernel is the Perron–Frobenius operator of T with respect to the absolutely continuous invariant probability measure. We give a large class of unbounded functions f for which the partial sums of f ◦T i satisfy both a central limit theorem and a bounded law of the iterated logarithm. For the same class, we prove that the partial sums of f (Yi) satisfy a strong invariance principle. When the class is larger, so that the partial sums of f ◦ T i may belong to the domain of normal attraction of a stable law of index p ∈ (1,2), we show that the almost sure rates of convergence in the strong law of large numbers are the same as in the corresponding i.i. d. case. Résumé. On considère une classe de transformations dilatantes T de [0,1] ayant un point fixe neutre, ainsi que les chaînes de Markov associées Yi , dont le noyau de transition est l’opérateur de Perron–Frobenius de T par rapport à l’unique mesure de probabilité T -invariante possédant une densité. On montre une loi du logarithme itéré bornée pour les sommes partielles de f ◦T i , lorsque f appartient à une classe de fonctions non bornées. Pour la même classe, on montre un principe d’invariance fort pour les sommes partielles de f (Yi). Lorsqu’on élargit la classe de fonctions, jusqu’à inclure des fonctions f pour lesquelles les sommes partielles de f ◦ T i appartiennent au domaine d’attraction normal d’une loi stable d’indice p ∈ (1,2), on montre que les vitesses de convergence dans la loi forte des grands nombres sont les même que dans le cas i.i. d. correspondant.

Common CaUses of PleUral effUsIons In the ICU Abdominal Surgery

Pleural disease in itself is an unusual cause for admission to the intensive care unit (ICU). Conditions potentially requiring ICU admission include a large pleural effusion causing acute respiratory failure, hemothorax producing respiratory or hemodynamic compromise, secondary spontaneous pneumothorax with respiratory failure, empyema with sepsis, and reexpansion pulmonary edema. Pleural complications of disease processes and procedures performed in the ICU are common, however, and the changes in respiratory physiology are additive to that of the underlying lung disease. The development of a pneumothorax in a critically ill patient, particularly in mechanically ventilated patients, may be a life-threatening event. Pleural effusions may be overshadowed by the illness requiring ICU admission in the critically ill patient. Pleural effusions and pneumothoraces may not be detected on chest radiographs because the radiologic appearance may differ in the supine patient.
ENHANCEMENT OF QOS IN MOBILE MULTIMEDIA APPLICATIONS DURING VERTICAL HANDOFF IN HETEROGENEOUS NETWORK

Multimedia applications in wireless communication have been increased in recent years. A variety of wireless access technologies are introduced for various needs. The abundant increase in mobile computing devices and different networking systems leads to the support of user’s mobility in Heterogeneous Wireless Networks (HWN). This paper addresses a Scheduling Based Vertical Handover Management Scheme (SBVHM) when a user migrate between WLAN and WiMAX for seamless and ubiquitous access. Various wireless technologies such as wireless LAN, WiMAX and 3GPP are interlaced to support many wireless services in global environment. In addition QoS has become more significant in many applications where wireless network resources are utilized. The proposed scheduling based vertical Handover management scheme analyses the QoS enhancement of the mobile user in a Heterogeneous network. Our simulation results show that by introducing proper scheduling, the QoS parameters such as Reauthentication delay and Signalling Cost are reduced significantly. The algorithms Genetic Queuing, Proportionally Fair Queuing and WiMAX QoS Aware Load Balancing are proposed in the scheduling process during handover. The simulation is implemented using NS-2 and the experimental results are obtained for the proposed algorithms and compared with the standard scheme.

The Changing Geographies of Backpacker Tourism in South-East Asia

South-East Asia has the oldest backpacker trails. This paper examines the geographies of such flows, drawing upon the largest survey to date of backpackers in Asia using qualitative research in a longitudinal study from the 1970s to the 2000s. Backpacker trails have changed significantly and new routes have emerged including the ‘northern trail’ (Bangkok - Cambodia - Vietnam - Laos). Changing routes are to be expected (backpackers constantly seek new places, pioneering for later mass tourism),however, this paper suggests that fundamentally, these changing trails are due to external variables combining travel innovations (low cost airlines, and other new transport networks); exogenous shock (political instability and terrorism); and growing regional competition, specifically emerging ‘exotic’ destinations such as Vietnam and Cambodia. Key words: backpackers; small-scale tourism; travel choice; motivation
Accounting for Rice Productivity Heterogeneity in Ghana: The Two-Step Stochastic Metafrontier Approach

Rice yields among agro-ecological zones are heterogeneous. Farmers, researchers and policy makers are making frantic efforts to bridge rice yield gaps between agro-ecological zones through the promotion of improved agricultural technologies (IATs). Farmers are also modifying these IATs and blending them with indigenous farming practices (IFPs) to form farmer innovation systems (FISs). Also, different metafrontier models have been used in estimating productivity performances and their drivers. This study used the two-step stochastic metafrontier model to estimate the productivity performances of rice farmers and their determining factors in GSZ, FSTZ and CSZ. The study used both primary and secondary data. Farmers in CSZ are the most technically efficient. Technical inefficiencies of farmers are negatively influenced by age, sex, household size, education years, extension visits, contract farming, access to improved seeds, access to irrigation, high rainfall amount, less lodging of rice, and well-coordinated and synergized adoption of technologies. Albeit farmers in CSZ are doing well in terms of rice yield, they still have the highest potential of increasing rice yield since they had the lowest TGR. It is recommended that government through the ministry of food and agriculture, development partners and individual private companies promote the adoption of IATs as well as educate farmers on how to coordinate and synergize the adoption of the whole package. Contract farming concept and agricultural extension intensification should be vigorously pursued to the latter. Keywords—Efficiency, farmer innovation systems, improved agricultural technologies, two-step stochastic metafrontier approach.
1 Differential effects of red yeast rice , Berberis aristata 2 and Morus alba extracts , active components of 3 LopiGLIK ® , on PCSK 9 in HepG 2 cells 4

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is the key regulator of low-density 18 lipoprotein cholesterol (LDL-C) plasma levels. We previously observed that treatment of 19 dyslipidemic subjects with nutraceutical combination containing red yeast rice (monacolin K 3.3 mg), 20 Berberis aristata cortex extract (Berberine 531.25 mg) and Morus alba leaves extract (121 deoxynojirimycin 4 mg) (LopiGLIK®) did not alter the plasma PCSK9 levels. Thus, the aim of the 22 present study was to investigate the effect of these three components on PCSK9 expression in HepG2 23 cell line in relationship to their effects on LDL-C cellular uptake. HepG2 cell line were incubated with 24 Berberis aristata cortex extract (BCE), red yeast rice (RYR) and Morus alba leaves extract (MLE) alone 25 or in combination for 24h. RYR (50 μg/mL) increased PCSK9 protein expression (WB and ELISA 26 assays), PCSK9 mRNA and its promoter activity. BCE (40 μg/mL) reduced PCSK9 expression, mRNA 27 levels and promoter activity. MLE determined a concentration-dependent inhibition of PCSK9 at 28 mRNA and protein levels, with a maximal reduction at 1 mg/mL; no significant changes in PCSK9 29 promoter activity were found. MLE also downregulates the expression of fatty acid synthase and 30 HMG-CoA reductase mRNA levels. The combination of RYR, BCE and MLE reduced PCSK9 at 31 mRNA, protein, and promoter activity. Finally, this combination induced the LDL receptor and LDL32 C uptake by HepG2 cells. In conclusion, the positive effect of MLE on PCSK9 supports the rational of 33 using this nutraceutical combination to control hyperlipidemic conditions. 34
The impact of fire on habitat use by the short-snouted elephant shrew (Elephantulus brachyrhynchus) in North West Province, South Africa

ABSTRACT Several studies have investigated the response of small mammal populations to fire, but few have investigated behavioural responses to habitat modification. In this study we investigated the impact of fire on home range, habitat use and activity patterns of the short-snouted elephant shrew (Elephantulus brachyrhynchus) by radio-tracking individuals before and after a fire event. All animals survived the passage of fire in termite mound refugia. Before the fire, grassland was used more than thickets, but habitat utilization shifted to thickets after fire had removed the grass cover. Thickets were an important refuge both pre- and post-fire, but the proportion of thicket within the home range was greater post-fire. We conclude that fire-induced habitat modification resulted in a restriction of E. brachyrhynchus movements to patches of unburned vegetation. This may be a behavioural response to an increase in predation pressure associated with a reduction in cover, rather than a lack of food. This study highlights the importance of considering the landscape mosaic in fire management and allowing sufficient island patches to remain post-fire ensures the persistence of the small mammal fauna.
