Relationships between Lightning Location and Polarimetric Radar Signatures in a Small Mesoscale Convective System

Abstract On 19 June 2004, the Thunderstorm Electrification and Lightning Experiment observed electrical, microphysical, and kinematic properties of a small mesoscale convective system (MCS). The primary observing systems were the Oklahoma Lightning Mapping Array, the KOUN S-band polarimetric radar, two mobile C-band Doppler radars, and balloonborne electric field meters. During its mature phase, this MCS had a normal tripolar charge structure (lightning involved a midlevel negative charge between an upper and a lower positive charge), and flash rates fluctuated between 80 and 100 flashes per minute. Most lightning was initiated within one of two altitude ranges (3–6 or 7–10 km MSL) and within the 35-dBZ contours of convective cells embedded within the convective line. The properties of two such cells were investigated in detail, with the first lasting approximately 40 min and producing only 12 flashes and the second lasting over an hour and producing 105 flashes. In both, lightning was initiated in or nea.
FAINT SUBMILLIMETER GALAXIES IDENTIFIED THROUGH THEIR OPTICAL/NEAR-INFRARED COLORS. I. SPATIAL CLUSTERING AND HALO MASSES

The properties of submillimeter galaxies (SMGs) that are fainter than the confusion limit of blank-field single-dish surveys ( 2 mJy) are poorly constrained. Using a newly developed color selection technique, Optical-Infrared Triple Color (OIRTC), that has been shown to successfully select such faint SMGs, we identify a sample of 2938 OIRTC-selected galaxies, dubbed Triple Color Galaxies (TCGs), in the UKIDSS-UDS field. We show that these galaxies have a median 850 μm flux of mJy (equivalent to a star formation rate SFR yr−1 based on spectral energy distribution fitting), representing the first large sample of faint SMGs that bridges the gap between bright SMGs and normal star-forming galaxies in S850 and LIR. We assess the basic properties of TCGs and their relationship with other galaxy populations at . We measure the two-point autocorrelation function for this population and derive a typical halo mass of log10( ) , , and at , 2–3, and 3–5, respectively. Together with the bright SMGs ( mJy) and a comparison sample of less far-infrared luminous star-forming galaxies, we find a lack of dependence between spatial clustering and S850 (or SFR), suggesting that the difference between these populations may lie in their local galactic environment. Lastly, on the scale of at we find a tentative enhancement of the clustering of TCGs over the comparison star-forming galaxies, suggesting that some faint SMGs are physically associated pairs, perhaps reflecting a merging origin in their triggering.
Mechanical basis for slip along low‐angle normal faults

The existence of active low‐angle normal faults is much debated because (1) the classical theory of fault mechanics implies that normal faults are locked when the dip is less than 30° and (2) shallow‐dipping extensional fault planes do not produce large earthquakes (M > 5.5). However, a number of field observations suggest that brittle deformation occurs on low‐angle normal faults at very shallow dip. To reconcile observations and theory, we use an alternative model of fault reactivation including a thick elasto‐plastic frictional fault gouge, and test it at large strain by the mean of 2D mechanical modeling. We show that plastic compaction allows reducing the effective friction of faults sufficiently for low‐angle normal faults to be active at dip of 20°. As the model predicts that these faults must be active in a slip‐hardening regime, it prevents the occurrence of large earthquakes. However, we also evidence the neoformation of Riedel‐type shear bands within thick fault zone, which, we believe, may be responsible for repeated small earthquakes and we apply the model to the Gulf of Corinth (Greece).
Spectral and polarization study of the double relics in Abell 3376 using the GMRT and the VLA

Double radio relics in galaxy clusters are rare phenomena that trace shocks in the outskirts of merging galaxy clusters. We have carried out a spectral and polarization study of the spectacular double relics in the galaxy cluster A3376 using the Giant Metrewave Radio Telescope at 150 and 325 MHz and the Very Large Array at 1400 MHz. The polarization study at 1400 MHz reveals a high degree of polarization (~30%) and aligned magnetic field vectors (not corrected for Faraday rotation) in the eastern relic. A highly polarized (>60%) filamentary radio source of size ~300 kpc near the eastern relic and north of the bent-jet radio galaxy is detected for the first time. The western relic is less polarized and does not show aligned magnetic field vectors. The distribution of spectral indices between 325 and 1400 MHz over the radio relics show steepening from the outer to the inner edges of the relics. The spectral indices of the eastern and the western relics imply Mach numbers in the range 2.2 to 3.3. Remarkable features such as the inward filament extending from the eastern relic, the highly polarized filament, the complex polarization properties of the western relic and the separation of the BCG from the ICM by a distance >900 kpc are noticed in the cluster. A comparison with simulated cluster mergers is required to understand the complex properties of the double relics in the context of the merger in A3376. An upper limit (log(P(1.4GHz) W/Hz < 23.0) on the strength of a Mpc size radio halo in A3376 is estimated.
The granularity of weakly occupied bosonic fields beyond the local density approximation

We examine ground state correlations for repulsive, quasi one-dimensional bosons in a harmonic trap. In particular, we focus on the few particle limit N=2, 3, 4, …, where exact numerical solutions of the many particle Schrödinger equation are available, by employing the multi-configuration time-dependent Hartree method. Our numerical results for the inhomogeneous system are modeled with the analytical solution of the homogeneous problem using the Bethe ansatz and the local density approximation. Tuning the interaction strength from the weakly correlated Gross–Pitaevskii to the strongly correlated Tonks–Girardeau regime reveals finite particle number effects in the second-order correlation function beyond the local density approximation.
Fragments of hot and metasomatized mantle lithosphere in Middle Miocene ultrapotassic lavas, southern Tibet

Uplift of the Tibetan Plateau and its infl uence on our global climate have been the focus of numerous studies. Miocene potassic to ultrapotassic volcanism is widespread in southern Tibet and has been generally attributed to convective removal of collision-thickened Asian lithosphere, which is also responsible for the uplift of the plateau. An implicit assumption of this model is the existence of a hydrous, metasomatized (i.e., phlogopite bearing) lithospheric mantle that remained after the convective thinning and was subsequently heated to form small-volume melts. If such a lithospheric mantle was present in the Miocene, it implies further change since that time, as seismic velocities indicate that cold and strong upper mantle occurs beneath the thick crust in southern Tibet. Here we describe peridotite xenoliths entrained in Middle Miocene ultrapotassic lavas from Sailipu, southern Tibet. The results suggest the existence of hot, highly metasomatized lithospheric mantle beneath southern Tibet during the Middle Miocene, and thus support the idea that convective thinning of the lithosphere was responsible for the uplift of the plateau. The relict mantle was later removed or squeezed northward by the underthrusting Indian continental lithosphere, which terminated magmatism in southern Tibet and played a role in creating the entire plateau.
Dictation as a Veritable Tool for Language Proficiency on Project Educational Reform in Nigeria

Dictation is a valuable language teaching and learning device that has been used for centuries though often ignored by teachers. It is a writing activity that involves writing down what someone says and or reads out as it is being said or immediately after it is said. Given the background of unsatisfactory performance of learners of English language in Nigeria this paper is an attempt to put a useful but now undervalued technique back into the language teaching activities. It contends that effective use of dictation activities will help to improve students’ proficiency in the four aspects of English language among the second learners of English language in a country like Nigeria. Nigeria is a multi-lingual country and English language has always been treated as a compulsory subject. To this end, an attempt is made in this paper to explore how dictation can be used as a device to improve students’ performance, especially in the current school reform. The paper equally suggests that the curriculum planners at the secondary school level should, as a matter of priority, include dictation activities in the syllabuses. It concludes that there should be consistent application of dictation activities. By doing this in the classroom, they would be making significant contributions to the current school reform project of the nationlearners.
Journal of Geophysical Research: Atmospheres An evaluation of atmospheric rivers over the North Paciﬁc in CMIP5 and their response to warming under RCP 8.5

Landfalling atmospheric rivers over the North Paciﬁc are evaluated in historical (1980–2005) simulations from 28 models participating in the ﬁfth phase of the Coupled Model Intercomparison Project (CMIP5) and compared to the Modern-Era Retrospective Analysis for Research and Applications and ERA-Interim reanalyses. Landfalling dates are identiﬁed as having spatially elongated high wind and moisture features in physical proximity to the coastline. Model performance relative to reanalysis is found to be quite variable. The majority can resolve the spatial structure of landfalling events, but few correctly resolve the frequency distribution, interannual variability in number and amplitude of moisture ﬂux, and median landfalling latitude. The response of a subset of high-performing models to projected warming at the end of the 21st century is investigated using Representative Concentration Pathway (RCP) 8.5 (2070–2100) projections. Selected models show a broadening of the frequency distribution, with the largest increase in frequency occurring equatorward of peak historical frequency. While there is a robust increase in AR-related moisture transport compared to the historical period, this increase is not linked to more extreme AR events within the context of the projected future climate. The occurrence of years with many AR dates is greater at the end of the 21st century than during the historical period. The equatorward increase in peak historical frequency is colocated with increases in the 850 and 250 hPa zonal winds. The response in moisture ﬂux to warming is mostly thermodynamic, but equatorward of its peak distribution, it is dominated by a dynamic response. ARs to warming: CanESM2, MPI-ESM-LR, CNRM-CM5, ACCESS1-0, ACCESS1-3, EC-EARTH, and CCSM4.
Corporate Aging and Takeover Risk

Although growth opportunities fade and profitability declines as firms mature, older firms are no more likely to be acquired than young firms are. This article documents and explains that phenomenon. We argue that, because mature organizations are rationally less flexible, they are more costly to integrate and therefore comparatively unattractive acquisition candidates. The evidence supports this explanation of the negative age dependence of takeover hazard. The evidence also shows that negative exogenous shocks to merger benefits further reduce the takeover hazard of mature firms. We test many alternative explanations and find no evidence that they can explain the hazard decline.
An empirical analysis of exchange rate volatility on export trade in a developing economy

This paper investigates the impact of exchange rate volatility on export in Nigeria. The paper employed three models, viz: Ordinary Least Square (OLS); Granger causality test; and ARCH and GARCH techniques and also Augmented Dickey-Fuller technique was used in testing the presence of unit root. The results of unit root suggested that all the variables in the model are stationary at first difference, while causality test revealed that there is causation between export and exchange rate in the country, but the causation flows from exchange rate to export. Thus, exchange rate causes export. Furthermore, ARCH and GARCH results suggested that the exchange rate is volatile nevertheless export is found to be non-volatile. The study further showed that exchange rate is impacting positively on export, as shown by the regression results. The elasticity results revealed that, the demand for Nigerian products in the World market is fairly elastic. Therefore, for export to improve and foreign exchange earnings increase, the country should depreciate its currency, thereby reducing the price of its products so as to increase demand, which is changing from import-led to export-led economy. Consequently, in order to improve exports, efficient delivery services are needed, such as; power supply, energy resources and infrastructure. The significance of this paper is that, it stands to be a guide to policy makers. It has also push forward empirical discourse and provided literature to future research. Finally, this research recommends the pursuance of a stable and sustainable exchange rate policy and to put in place measures that will promote greater exchange rate stability and improve terms of trade, promote greater openness in order to augment non-oil exports. Hence, these measures could greatly promote export trade.
Leveraging National Auditing Criteria to Implement Cybersecurity Safeguards for the Automotive Emergency Response Vehicles : A case study from Finland

A modern Emergency Response Vehicle (ERV) is a combination of emergency services and functional mobile office on the wheels. The mobile office is aiming to leverage the benefits of fixed office while moving on the wheels. Researchers have observed that emergency response personnel including Law Enforcement Authorities (LEAs), Police and border guards, could be on the duty while having possibility to use same services compared to fixed office. On the one hand, demand of mobile office has significantly improved the emergency response services. On the other hand, emergency vehicle designers should rethink the demand of users. This resulted into modern standard emergency response vehicle with three compartments including cabin, office space and transport space. During our research study, users have registered special demand for mobile office, to meet this demand, designers and engineers have combined a modern vehicle platform with computers, monitors, wireless connectivity and many other devices needed in everyday activities. A set of standards has been released by local and global organisations to help building standard vehicle for emergency responses. However, there is continue challenge, the standards are not covering information and cyber security properly. This research paper fulfils that gap by applying the Finnish National Security Auditing Criteria version 2 (KATAKRI II) on top of eight asset classes that have recognised in Mobile Object Bus Integration (MOBI) project. The outcome is a pragmatic proposal that provides set of safeguards for guaranteeing ERV information and cyber security. This paper presents the information and cyber security safeguards utilising standards presented in Finnish National Auditing Criteria and applying in emergency response vehicles.
New penguin remains from the Pliocene of Northern Chile

Until recently, all described fossil penguin species from South America were recovered from the Atlantic coast. The description of three fossil species of Spheniscus from Peru and Chile now allows a clearer estimate of the historical diversity on the Pacific coast. Here we describe a further new species from a Pliocene level of the Bahía Inglesa Formation, northern Chile. This taxon, the first to be described from this sequence, is based on a partial skeleton lacking a skull. These remains are clearly referable to the living genus Pygoscelis, and share a mosaic of characters with extant species of the genus. Pygoscelis grandis sp. nov. was around the size of a King Penguin, and therefore much larger than any extant Pygoscelis species. Our cladistic analysis places P. grandis within the Pygoscelis clade as the sister taxon of living representatives. Living species of Pygoscelis have a sub-Antarctic distribution, and the presence of this species slightly south of the Tropics during the Pliocene may relate to end Neogene global cooling.
Value Chain Analysis of the Pre and Post-Harvest Factors Deteriorating the Quality of Coffee in the Chole District, Oromia Region, Ethiopia

The research aimed to identify the quality deteriorating factors at pre and post-harvest level of the coffee value chain in the Arsi Zone of Chole district. Different research strategies were employed to answer the research questions, which include; desk study, interview, focus group discussion, field survey and observation were employed to collect pertinent information on the pre-harvest and post-harvest factors within the value chain. Data were collected and analyzed by different methods to identify which practices were the possible factors deteriorating the quality of the coffee in the value chain. The result indicated that, at the pre-harvest level, inadequate use of fertilizers, limited moisture, lack of practicing rejuvenation and pruning, coffee wilt and berry diseases, insect pest incidence were the main factors to deteriorate the quality coffee production. At the post-harvest level, carrying out of improper harvesting practices, hardly use of recommended packaging materials, unconducive storage system, mixing of water and foreign matters on dried coffee were some of the factors affecting the quality of the coffee. To address the identified factors, at the pre and postharvest level along the coffee value chain, applied recommendations were given to selected stakeholders. Keywords : coffee, value chain, quality, pre-harvest, post-harvest
Development and Testing of Message Scheduling Middleware Algorithm with SOA for Message Traffic Control in IoT Environment

Nowadays, in most of the applications, Internet of Things (IoT) is being used, multiple clients are indirectly connected to sensing devices through messaging broker and their interaction happens through message exchanger. Day by day number of clients and sensing devices are increasing and subsequently message traffic management becoming key research area. In case of overloaded message traffic, IoT broker system faces delayed messaging and so sensor activation and response gets delayed. With this identified problem, present research focused on development of new middleware (broker) architecture for IoT which can handle message queue more efficiently. With changing requirement trends, traditional service-oriented architecture (SOA) model has many architecture design issue. Traditional SOA does not support multiple protocol request communication. Hence, this paper focuses on the design of the message scheduling broker for IoT environment with hybrid protocol routing e.g. Extensible Messaging and Presence Protocol (XMPP), Constrained Application Protocol (CoAP), MQ Telemetry Transport (MQTT) protocols considered like one request and it is filtered by broker based on their calculated priority. Additionally, proposed scheduling algorithm uses priority queue model which is considered as a reference messaging model. Multiple queues model is developed to increase the efficiency of the algorithm. Such middleware provides a solution for message delay issue with multiple protocol request handling. The system is tested for MQTT, XMPP and CoAP message protocols with respect to service time and MQTT protocol performance are found more efficient during IoT sensor test using Apache HIVE testing platform as Apache HIVE is a data warehouse software project for providing data summarization, query and analysis.
Genetic and Phenotypic Evaluation of Hardhenu Crossbred Cattle Using Reproduction Traits

Milk production is one of the most important traits in dairy cattle. Hence, in most of the genetic improvement programmes in the country, selection is generally focussed on production traits, whereas, reproductive performance of the animal is not being given the due emphasis. The most striking consequence is that large number of high yielder cows are becoming repeat breeder and infertile which results in increased generation interval and thereby reduces the genetic gain per unit of time. Therefore, need was felt to consider reproduction traits in addition to production traits during selection programmes. Selection considering reproduction traits along with production performance was advocated under Indian conditions due to small number of daughters per sire and at the same time to improve the accuracy and efficiency of sire evaluation.
Effect of anthropogenic warming on microbial respiration and particulate organic carbon export rates in the sub-Antarctic Southern Ocean

ABSTRACT: Microbial respiration of particulate organic carbon (POC) is one of the key processes controlling the magnitude of POC export from the surface ocean and its storage on long timescales in the deep. Metabolic processes are a function of temperature, such that warming sea temperatures should increase microbial respiration, potentially reducing POC export. To investigate this in the Southern Ocean, we measured microbial oxygen consumption of large particles over a 10°C temperature range (summer maximum +8°C) to then estimate the decrease in export by 2100. Our results showed that POC-normalised respiration increased with warming. We estimate that POC export (scaled to primary production) could decrease by 17 ± 7% (SE) by 2100, using projected regional warming (+1.9°C) from the IPCC RCP 8.5 (‘business-as-usual’ scenario) for our sub-Antarctic site. Increased microbial respiration is one of many processes that will be altered by future climate change, which could all modify carbon storage in the future. Our estimate of the potential decline in carbon sequestration is within previous estimates from lab and field experiments, but higher than simple mechanistic models. To explore our results further, we used the metabolic theory of ecology (MTE) to determine the activation energy of microbial respiration, which was 0.9 eV. This is higher than classical MTE (0.6-0.7 eV), suggesting that sub-Antarctic microbes are particularly sensitive to temperature change. Such regional characteristics in the response of organisms to increased temperatures should be accounted for in large-scale or global model analyses to ensure that the results do not underestimate microbial responses to warming.
