SOStab: a Matlab Toolbox for Transient Stability Analysis

This paper presents a new Matlab toolbox, aimed at facilitating the use of polynomial optimization for stability analysis of nonlinear systems. Indeed, in the past decade several decisive contributions made it possible to recast this type of problems as convex optimization ones that are tractable in modest dimensions. However, available software requires their user to be fluent in Sum-of-Squares programming, preventing them from being more widely exploited by practitioners. To address this issue, SOStab entirely automates the writing and solving of optimization problems, and directly outputs relevant data for the user, while requiring minimal input. In particular, no specific knowledge of optimization is needed for implementation. The toolbox allows a user to obtain outer and inner approximates of the region of attraction of the operating point of different grid connected devices such as synchronous machines and power converters.
Observation of α‐stable noise induced millennial climate changes from an ice‐core record

The last glacial period showed millennium scale climatic shifts between two different stable climate states. The state of thermohaline ocean circulation probably governs the climate, and the triggering mechanism for climate changes is random fluctuations of the atmospheric forcing on the ocean circulation. The high temporal resolution paleo‐climatic data from ice‐cores are consistent with this picture and a bi‐stable climate pseudo‐potential can be derived. It is found that the fast time scale noise forcing the climate contains a component with an α‐stable distribution. As a consequence the abrupt climatic changes observed could be triggered by single extreme events. These events are related to ocean‐atmosphere dynamics on annual or shorter time scales and could indicate a fundamental limitation in predictability of climate changes.
Production, Release and Transport of Noble Gases in the Continental Crust

Noble gases within the crust originate from three main sources: the atmosphere, introduced into the crust dissolved in groundwater; the mantle, in regions of magmatic activity; and those produced in the crust by the result of radioactive decay processes. The continental crust contains approximately 40% of the terrestrial radioelements (Rudnick and Fountain 1995) that produce noble gases and, after the mantle and the atmosphere, forms the third major terrestrial noble gas reservoir (neglecting the core). In addition to these sources, contributions from interplanetary dust particles (IDP), cosmic ray interaction with the crustal surface and anthropogenic noble gases can in some cases be a significant source of noble gases in crustal materials. The use of noble gases to understand the role of fluids in different geological settings relies on their low natural abundance and chemical inertness. The low abundance of noble gases in crustal systems and their distinct isotopic character means that contributions from these different sources can often be resolved and quantified. With this, information is gained about the source of associated fluids, the environment from which they originated the physical manner in which they have been transported to the sampling site and the different phases that may have interacted within the crustal fluid system. This is only possible, however, with a detailed understanding of the processes that control the concentration and isotopic composition of the noble gases in different crustal environments. The first part of this chapter deals with the three different mechanisms of noble gas production within the crust—radiogenic, nucleogenic, fissiogenic (Fig. 1⇓). We show how production ratios are affected not only by the source region radioelement concentration, but in the case of nucleogenic reactions, also by the spatial distribution and concentration of the target elements. For completeness we consider cosmogenic noble gas production rates and Interplanetary …
Use of Crown Feature Analysis to Separate the Two Pine Species in QuickBird Imagery

Tree species-specific estimates with spaceborne high-resolution imagery improve estimation of forest biomass which is needed to predict the long term planning for the sustainable forest management(SFM). This paper is a contribution to develop crown distinguishing coniferous species, Pinus densiflora and Pinus koraiensis, from QuickBird imagery. The proposed feature analysis derived from shape parameters and first and second-order statistical texture features of the same test area were compared for the two species separation and delineation. As expected, initial studies have shown that both formfactor and compactness shape parameters provided the successful differentiating method between the pine species within the compartment for single crown identification from spaceborne high resolution imagery. Another result revealed that the selected texture parameters - the mean, variance, angular second moment(ASM) - in the infrared band image could produce good subset combination of texture features for representing detailed tree crown outline.
Identification of transtensional and transpressional features in the Sea of Marmara using onshore-offshore seismic and geodetic data

: The scope of the study is to determine transtensional and transpressional features along the North Anatolian Fault beneath the Sea of Marmara, using seismic and geodetic data. For this purpose, focal mechanisms of small size NAF earthquakes, recorded by broadband stations and OBSs, have been derived and used as a tool to identify the transtensional and transpressional features. The focal mechanisms of: (1) small to moderate size events are obtained by the CMT inversion technique of Kuge (2003), using onshore waveform data from 2002–2015, (2) micro-earthquakes are obtained using the technique of Horiuchi (2015), using offshore waveform data recorded by 15 OBS stations from 2015–2016. Furthermore, published GPS velocities are used to determine the style of faulting and strain rates. The geodetic horizontal crustal strain rates are determined at equally spaced grid points by interpolating northing and easting components of the 112 GPS vectors from 1994–2013. The results indicate that extensional and strike-slip style deformation dominates the region, while contractional features are rare. Significant extension is observed in Çınarcık Basin and the area between Marmara Island and Central Basin. Yalova-Çınarcık region shows predominantly N-S extension while the Çınarcık Basin events show NE-SW extension. Compressional or transpressional features are derived to the west of Marmara Island and Ganos and in the Central segment extending from Central Basin toward Çınarcık Basin. The GPS strain rate results point out the highest values, 24 × 10 –8 /year, in Çınarcık Basin, while the lowest values, 11 × 10 –8 /year, are observed in Central Marmara. The highest strain rates in both edges of the fault segment in Çınarcık Basin can be indicative of a steadily creeping fault segment. In turn, lower strain rates in the Central Marmara region suggest that this segment of the NAF is locked.
Turbulent mixing and mesoscale distributions of late‐stage fish larvae on the NW Shelf of Western Australia

Light traps were deployed to describe vertical and cross-shelf distributions of late-stage larval fishes during five cruises in each of the 1997/98 and 1998/99 summers in the region of the Gulf of Exmouth on the southern North West Shelf of Western Australia. At each light trap station on a cross-shelf transect we measured water temperature, salinity and chlorophyll a and used vertical plankton tows to estimate zooplankton biomass and copepod abundance. Current meters were deployed on moorings near the transect and the data used to model flows and mixing on the NW Shelf and in the Gulf. The majority of reef, pelagic and baitfish larvae (81, 83 and 66% respectively) were collected at only two stations that marked the boundary between stratified waters offshore and well-mixed water within the Gulf. Most baitfishes (primarily Spratelloides spp.) were captured by traps deployed near the seabed, while reef fishes (mostly pomacentrids, lethrinids and siganids) and pelagic species (mostly scombrids and carangids) were captured in traps deployed near surface. Catch composition varied between summers with 64% of baitfishes collected in the first summer, while the majority of reef and pelagic fishes (81 and 80% respectively) were captured in the second summer. Modelling of circulation showed that the velocity of tidal currents was enhanced by constriction of flow between NW Cape and South Muiron Island and by shallowing of the shelf. Flood-tide intrusions of water allowed the thermocline to move up the continental shelf, upwelling cool nutrient-rich water that was then mixed throughout the entire water column at stations in the mouth of the Gulf. This upwelling and mixing resulted in higher chlorophyll a concentrations and copepod abundances either as a result of local in situ growth or advection/aggregation processes, and may account for the great abundances of late-stage fish larvae in the mouth of the Gulf.
Patterns of geographic distribution and conservation of the open-habitat avifauna of southeastern Brazilian mountaintops (campos rupestres and campos de altitude)

Montane open-habitats of southeastern Brazil are represented by the campos rupestres (principally in the Espinhaco Range) and by the campos de altitude (in the Serra do Mar and Serra da Mantiqueira). In spite of the occurrence of endemic species in both vegetation types, an analysis and synthesis of their bird communities have never been conducted. In this paper, we present an avifaunal survey of these areas, describe patterns of geographic distribution, and comment on the conservation of those open-habitats and their avifauna. A total of 231 bird species was recorded in the open-habitats of southeastern Brazilian mountaintops. In the campos rupestres, 205 species were recorded, while in the campos de altitude, the total was 123 species. Five patterns of distribution are recognizable among birds occurring in these habitats: non-endemic (191 species), Atlantic Forest endemics (26 species), Cerrado endemics (6 species), Caatinga endemic (1 species), and montane open-habitat endemics (7 species). In spite of the presence of several protected areas in those regions, the existing reserves do not guarantee the conservation of their important vegetation types and their avifaunas under current low levels of implementation. Since several endemic and threatened bird species live in the campos rupestres and campos de altitude, more efforts must be directed for their conservation.
Stream chemistry in the eastern United States. 2. Current sources of acidity in acidic and low acid-neutralizing capacity streams

The authors examined anion composition in National Stream Survey (NSS) data in order to evaluate the most probably sources of current acidity in acidic and low acid-neutralizing capacity (ANC) streams in the eastern US. Acidic streams that had almost no organic influence (less than 10% of total anions) and sulfate and nitrate concentrations indicative of evaporative concentration of atmospheric deposition were classified as acidic due to acidic deposition. These acidic streams were located in small (<30 km{sup 2}) forested watersheds in the Mid-Atlantic Highlands (an estimated 1,950 km of stream length) and in the Mid-Atlantic Coastal Plain (1,250 km). Acidic streams affected primarily by acidic deposition but also influenced by naturally occurring organic anions accounted for another 1,180 km of acidic stream length, and were located in the New Jersey Pine Barrens, plateau tops in the Mid-Atlantic and Southeast Highlands, and the Florida Panhandle. The total length of streams acidic due to acid mine drainage in the NSS (4,590 km) was about the same as the total length of acidic streams likely affected by acidic deposition (4,380 km). Acidic streams whose acid anion composition was dominated by organics were located in Florida and the Mid-Atlantic Coastal Plain. In Florida, mostmore » of the acidic streams were organic dominated, whereas about half of the streams in the Mid-Atlantic Coastal Plain were organic dominated. Organic-dominated acidic streams were not observed in the Mid-Atlantic and Southeast Highlands. « less
Iseite, Mn2Mo3O8, a new mineral from Ise, Mie Prefecture, Japan

Iseite, Mn2Mo3O8, a new mineral that is a Mn-dominant analogue of kamiokite, is found in the stratiform ferromanganese deposit, Shobu area, Ise City, Mie Prefecture, Japan. It is the first mineral species that includes both Mn and Mo as essential constituents. Iseite is iron-black in color and has a submetallic luster. It occurs as aggregates up to about 1 mm in size made of minute crystals (<20 μm). Iseite has a zoned structure closely associated with undetermined Mn-Fe-Mo oxide minerals with hexagonal forms, and it occasionally coexists with small amounts of powellite. Its Mohs hardness is 4-5, and its calculated density is 5.85 g/cm. The empirical formula of iseite is (Mn1.787Fe0.193)Σ1. 980Mo3.010O8. Its simplified ideal formula is written as Mn2Mo3O8. The mineral is isostructural with kamiokite (hexagonal, P63mc). The unit cell parameters are a = 5.8052 (3) Å, c = 10.2277 (8) Å, V = 298.50 (4) Å, and Z = 2. The Rietveld refinement using synchrotron radiation (λ = 0.413 Å) powder XRD data converges to Rwp = 3.11%, and confirms two independent Mn sites—tetrahedral and octahedral—in the crystal structure of iseite, indicating the structure formula MnMnMo3O8.

The prison population experiences significant health inequality and social exclusion (Department of Health 2002). Once incarcerated, prisoners are at increased risk of mental illness and have higher exposure to communicable diseases (WHO 2008). Prisoners generally have poorer health because imprisonment negatively impacts upon the health of the individual (WHO 2008). However, the prison setting offers a unique opportunity to implement targeted health promotion initiatives with a population that may have had very limited experience of accessing health services prior to incarceration. The World Health Organisation recognises the need for health promotion in prisons. This is evidenced in the Health in Prisons Project (HIPP), the aim of which is to support member states in improving health and health care in prisons, and to facilitate the links between prison health and public health systems at both national and international levels. In practice however, implementation of the HIPP is complex. This paper examines the challenges in promoting health in prisons globally and in Irish prisons specifically, given that the prison setting is omitted from the Irish National Health Promotion Strategy. Based on a qualitative research design that incorporated semi-structured interviews with a purposive sample of twelve leading figures in prison policy in Ireland, this paper discusses the need for health promotion interventions in Irish prisons. The paper also discusses the influence of organisational culture on attitudes of prison staff towards engaging in health promotion with prisoners and explores the problems posed by lack of national policy and funding for health promotion initiatives in the prison setting.
Effect of influent load fluctuation on the efficiency of vertical constructed wetlands treating dairy farm wastewater

Three vertical sub-surface flow (VSSF) constructed wetland (CW) systems (CW-1, CW-2 and CW-3) filled with different filter media, each 4 m 2 in area, planted with Arundo donax was operated for 4 years for treating dairy farm wastewater. The vertical CW systems received high fluctuations in influent concentrations and loads i

The work proposes policies to improve the environmental sustainability of distributed ledger technology (DLT). While the proof-of-work (PoW) consensus protocol requires large amounts of electricity, several DLT protocols consume much less, while still being sufficiently reliable and decentralized. To move from a PoW protocol to a greener system, such as proof-of-stake (PoS) or proof-of-authority (PoA), the consensus of the majority of miners (measured by their computing power) is required during the transition period to preserve the security requirements. Given that miners have an incentive to maintain the status quo, this paper illustrates various policies designed to bring about the transition. We aim to show that the current policy approach adopted by banking and financial regulators, based on the principle of technological neutrality, may need a reappraisal in order to consider the ‘sustainability’ criterion. Policymakers should not stifle financial innovation; nevertheless they should intervene if technology is a source of negative externalities.
Temporal evolution of very strong Trimpis observed at Darwin, Australia

Very strong phase and amplitude perturbations (Trimpis) of the very strong VLF transmission from NWC received in Darwin, Australia, enabled accurate measurement of the amplitude and phase of the scattered signal and of the time variation of these. The amplitude of the scattered signal decays as the logarithm of time, quite at odds with the exponential decay observed on classic Trimpis. During the amplitude decay, the phase of the scattered signal decreased at a decreasing rate. This is shown to be consistent with scattering from a bundle of sprite‐like, conducting columns extending some 50 km below the base of the ionosphere.
Cardiovascular Magnetic Resonance Versus Histopathologic Study for Diagnosis of Benign and Malignant Cardiac Tumours: A Systematic Review and Meta-Analysis

BACKGROUND The gold standard for diagnosis of cardiac tumours is histopathological examination. Cardiovascular magnetic resonance (CMR) is a valuable non-invasive, radiation-free tool for identifying and characterizing cardiac tumours. Our aim is to understand CMR diagnosis of cardiac tumours by distinguishing benign vs. malignant tumours compared to the gold standard. METHODS A systematic search was performed in the PubMed, Web of Science, and Scopus databases up to December 2022, and the results were reviewed by 2 independent investigators. Studies reporting CMR diagnosis were included in a meta-analysis, and pooled measures were obtained. The risk of bias was assessed using the Quality Assessment Tools from the National Institutes of Health. RESULTS A total of 2,321 results was obtained; 10 studies were eligible, including one identified by citation search. Eight studies were included in the meta-analysis, which presented a pooled sensitivity of 93% and specificity of 94%, a diagnostic odds ratio of 185, and an area under the curve of 0.98 for CMR diagnosis of benign vs. malignant tumours. Additionally, 4 studies evaluated whether CMR diagnosis of cardiac tumours matched specific histopathological subtypes, with 73.6% achieving the correct diagnosis. CONCLUSIONS To the best of our knowledge, this is the first published systematic review on CMR diagnosis of cardiac tumours. Compared to histopathological results, the ability to discriminate benign from malignant tumours was good but not outstanding. However, significant heterogeneity may have had an impact on our findings.
A description of QUALCOMM Automatic Satellite Position Reporting (QASPR(R)) for mobile communications

Two satellite position reporting has been introduced into the OmniTRACS mobile satellite communication system. This system significantly improves position reporting reliability and accuracy while simplifying the terminal's hardware. The positioning technique uses the original OmniTRACS TDMA timing signal formats in the forward and return link directions plus an auxiliary, low power forward link signal through a second satellite to derive distance values. The distances are then converted into the mobile terminal's latitude and longitude in real time. A minor augmentation of the spread spectrum profile of the return link allowed the resolution of periodic ambiguities. The system also locates the two satellites in real time with fixed platforms in known locations using identical mobile terminal hardware. Initial accuracies of 1/4 mile have been realized uniformly throughout the USA using a satellite separation of 22 degrees and there are no dead zones, skywaves, or cycle slips as found in terrestrial systems like LORAN-C.
Performance evaluation of image-based location recognition approaches based on large-scale UAV imagery

Recognizing the location where an image was taken, solely based on visual content, is an important problem in computer vision, robotics and remote sensing. This paper evaluates the performance of standard approaches for location recognition when applied to large-scale aerial imagery in both electro-optical (EO) and infrared (IR) domains. We present guidelines towards optimizing the performance and explore how well a standard location recognition system is suited to handle IR data. We show on three datasets that the performance of the system strongly increases if SIFT descriptors computed on Hessian-Affine regions are used instead of SURF features. Applications are widespread and include vision-based navigation, precise object geo-referencing or mapping.
