description: Digital contents are typically sold online through centralized and custodian marketplaces, which requires the trading partners to trust a central entity. We present FileBounty, a fair protocol which, assuming the cryptographic hash of the file of interest is known to the buyer, is trust-free and lets a buyer purchase data for a previously agreed monetary amount, while guaranteeing the integrity of the contents. To prevent misbehavior, FileBounty guarantees that any deviation from the expected participants' behavior results in a negative financial payoff; i.e. we show that honest behavior corresponds to a subgame perfect Nash equilibrium. Our novel deposit refunding scheme is resistant to extortion attacks under rational adversaries. If buyer and seller behave honestly, FileBounty's execution requires only three on-chain transactions, while the actual data is exchanged off-chain in an efficient and privacy-preserving manner. We moreover show how FileBounty enables a flexible peer-to-peer setting where multiple parties fairly sell a file to a buyer.

description: Oligoclase and labradorite crystals have been experimentally replaced by albite in an aqueous sodium silicate solution at 600°C and 2 kbars. The replacement is pseudomorphic and is characterised by a sharp chemical interface which progresses through the feldspar while preserving the crystallographic orientation. Reaction rims of albite, up to 50 μm thick, can be readily achieved within 14 days. Re-equilibration of plagioclase in an 18O-enriched sodium- and silica-bearing solution results in oxygen isotope redistribution within the feldspar framework structure. The observed characteristics of the reaction products are similar to naturally albitised plagioclase and are indicative of an interface-coupled dissolution–reprecipitation mechanism. Chemical analyses demonstrate that the albitisation is accompanied by the mobilisation of major, minor and trace elements also including elements such as Al and Ti which are commonly regarded as immobile during hydrothermal alteration. The results contribute to developing our understanding of the close association between large-scale albitisation and secondary ore mineralisation which is common in nature.

description: Applications of Riemannian quantum geometry to cosmology have had notable successes. In particular, the fundamental discreteness underlying quantum geometry has led to a natural resolution of the big bang singularity. However, the precise mathematical structure underlying loop quantum cosmology and the sense in which it implements the full quantization program in a symmetry reduced model has not been made explicit. The purpose of this paper is to address these issues, thereby providing a firmer mathematical and conceptual foundation to the subject.

description: This program provides teaching, research and extension assistance to small farmers operating small-scale aquaculture farms, which utilize natural water bodies to contribute to food production. Thus the program supports the development of the aquaculture industry and the economy of Florida. A specific objective was to bring together production, economic and marketing specialists in integrated demonstration of projects to optimize production systems (ponds, tanks, raceways cages and hybrid systems), spawning and hatchery techniques, microencapsulated feeds, batch plankton culture procedures, preventive aquatic animal health practices and product value. The program addresses problems/needs of small, limited resource and economically disadvantaged farmers and facilitates cooperation of specialists and county agents in finding solutions to various challenges encountered in the industry. Initially the project involved ten (10) existing and new farmers in counties within a one hundred (100) mile radius. Farmers currently growing fish and those interested in growing fish, with or without ownership of existing water bodies, were identified. The project began in July 2006 at FAMU Research and Extension Center, Quincy, Florida, where there are ponds; and it provided classroom and hands-on training and a farm visit was made with each farmer. A training curriculum was developed with modules and information used for the instruction. Fourteen farmers were trained on the best management practices and alternative methods for improvement of production systems for fish (e.g. Bait fish and Sturgeon). Marketing strategies were addressed to sustain the increased production of fish and profitability. Four ponds were revitalized and once per week pH, temperature, depth and dissolved oxygen data were collected as the ponds stabilized. Brochures were developed to support development of small scale enterprises, production of fmgerlings and utilization of existing natural resources and reduction of specialized inputs.

description: The temporally and geographically scattered Phanerozoic record of methane-seep deposits hampers reconstruction of the evolution of life in chemosynthesis-based ecosystems. Unlike modern, Cenozoic, and late Mesozoic seeps, many of the known older seep deposits are typified by assemblages with profuse rhynchonellide brachiopods. Late Triassic (Norian) limestone bodies in eastern Oregon are enclosed in deep-water strata, extend laterally for up to a few hundred meters, and contain the dimerelloid rhynchonellide Halorella in rock-forming quantities. The analysis of two large limestone bodies in the Rail Cabin Member of the Vester Formation exposed near Graylock Butte, Grant County, Oregon, fosters the reconstruction of the paleoenvironmental setting of these unusual Halorella deposits, resulting in the first recognition of Triassic methane-seep deposits. The faunal assemblage includes few fossils other than Halorella. Although occasionally found at seeps, the recognized nuculanids are not seep-endemic bivalves. A Nucinella-like bivalve and a possible permophorid bivalve were likely endemic to this chemosynthesis-based environment; related bivalves lived at Jurassic and Cretaceous seeps. The superabundant, mostly articulated brachiopod shells are enclosed in a variety of micrites, including peloidal to clotted micrite. Early fibrous cement, forming banded and botryoidal crystal aggregates, preferentially occurs at the margin of the large limestone bodies but is scarce overall. Peloidal to clotted micrite and banded and botryoidal cement are common constituents of methane-seep limestones. Their negative d13C values as low as 36‰ reveal that carbonate formation was induced by the oxidation of methane. The presence of pyrobitumen (i.e., metamorphosed crude oil) in the limestones may indicate that the seepage fluids contained oil in addition to methane. Apart from the diagnostic 13C-depleted carbonate phases, mud injections recognized in one of the two limestone bodies also bear testament to former seepage activity.

description: We have recently performed a relativistic $O(q^4)$ chiral expansion of the two-pion exchange $NN$ potential, and here we explore its configuration space content. Interactions are determined by three families of diagrams, two of which involve just $g_A$ and $f_π$, whereas the third one depends on empirical coefficients fixed by subthreshold $πN$ data. In this sense, the calculation has no adjusted parameters and gives rise to predictions, which are tested against phenomenological potentials. The dynamical structure of the eight leading non-relativistic components of the interaction is investigated and, in most cases, found to be clearly dominated by a well defined class of diagrams. In particular, the central isovector and spin-orbit, spin-spin, and tensor isoscalar terms are almost completely fixed by just $g_A$ and $f_π$. The convergence of the chiral series in powers of the ratio (pion mass/nucleon mass) is studied as a function of the internucleon distance and, for $r>$ 1 fm, found to be adequate for most components of the potential. An important exception is the dominant central isoscalar term, where the convergence is evident only for $r>$ 2.5 fm. Finally, we compare the spatial behavior of the functions that enter the relativistic and heavy baryon formulations of the interaction and find that, in the region of physical interest, they differ by about 5%.

description: We investigate two-dimensional Bose system with the long range interactions in the presence of disorder. Formation of the bound states at strong impurity sites gives rise to an additional depletion of the superfluid density. We demonstrate the existence of the intermediate superfluid state where the condensate and localized bosons present simultaneously. We find that interactions suppress localization and that with the increase of the boson density the system experiences a sharp delocalization crossover into a state where all bosons are delocalized. We map our results onto the three dimensional system of vortices in type II superconductors in the presence of columnar defects; the intermediate superfluid state maps to an intermediate vortex liquid where vortex liquid neighbors pinned vortices. We predict the depinning transition within the vortex liquid and depinning induced vortex lattice/Bose glass melting.

description: The effect of the thickness of ion exchange membranes has been investigated for electrodialysis (ED) and reverse electrodialysis (RED), both experimentally and through theoretical modeling. By developing a two-dimensional model based on Nernst-Planck theory, we theoretically find that reducing the membrane thickness benefits process performance only until a certain value, below which performance drops. For ED, an optimum thickness can be identified in the range of 10-20 microns, while for RED the maximum power density is found for membranes that are three times as thick. Model calculations compare well with experimental data collected with a series of homogeneous membranes with the same chemical composition and a thickness in the range of 10-75 microns. Our results show that the classical picture that membranes should be as thin as possible (as long as they remain pinhole-free and structurally stable) is insufficient, and must be replaced by a more accurate theoretical framework.

description: A total of 64 meat goats (6 months old) were used to investigate the effects of various doses of two anthelmintics on naturally occurring intestinal parasites in two feeding systems (32 animals each). Animals in the extensive system received grazing only and those in the semi-intensive system received grazing plus 1.1 kg of a 12% protein pellet per head per day. Animals in both systems received treatments of Moxidectin (MOX) and Ivermectin (IVM) at 0.275 mg/kg; 0.550 mg/kg and 0.825 mg/kg bodyweight and 0 mg/kg (CONT). Two males and 2 females were randomly assigned to each treatment. A single dose of MOX or IVM was administered orally to each treated animal at Day 0. A fecal sample was taken from each animal on Days 0, 7, 28, 56, and 84 for evaluation of parasite eggs. Body weights were taken on Days 0, 28, 56, and 84. Sampling began on March 8, 2005 and ended on June 15, 2005. In the extensive system, IVM-treated animals (19.95 kg) had a higher average bodyweight gain than those treated with MOX (17.14 kg). MOX-treated animals, 0.550 mg/kg had slightly higher bodyweight gain (5.77 kg) than CONT animals (5.14 kg). In IVM-treated animals, 0.825 mg/kg had the highest bodyweight gain (6 kg). In the semi-intensive system, MOX-treated animals (25.23 kg) had slightly higher average bodyweight gain than IVM-treated (24.64 kg). MOX-treated, 0.825 mg/kg and CONT animals had similar bodyweight gain (6.59 and 6.54 kg). IVMtreated animals, 0.825 mg/kg had the highest bodyweight gain (7.59 kg). Fecal samples showed marked reductions in parasite egg counts in MOX-, IVM-treated and CONT animals for both systems. In the extensive system, MOX-treated animals, had parasite eggs only in animals treated with 0.550 mg/kg whereas IVM-treated animals had no eggs in animals treated with 0.825 mg/kg, and CONT animals at the end of the study. In the semi-intensive system, no parasite eggs were detected in any sample in MOX- treated but were in CONT animals at the end of the study. In IVM-treated animals, 0.550 mg/kg, and CONT animals, no parasite eggs were detected at the end of the study.

In such a geometrization, the scalar curvature, R, plays a central role. A non-interacting model has a flat geometry (R=0), while R diverges at the critical point of an interacting one. Here, the information geometry is studied for a number of solvable statistical-mechanical models.

title: Are Universities Adequately Preparing Undergraduate Students for Careers as Professional Wildlife Biologists?
Creators: name: Strange, Trevon D.
Publisher: name: Utah State University
Year: 2024

description: The demands for diversely skilled wildlife biologists and scientific researchers in the wildlife profession are projected to increase. Increasing urbanization has affected wildlife management, and the recruitment of future wildlife professionals. Thus, state and federal supervisors in agencies that hire wildlife professionals are concerned that recent graduates of university wildlife programs lack the necessary skill-sets to address these complex contemporary wildlife management issues. My research sought to identify where the educational performance gaps may exist between university wildlife programs, wildlife agencies, and student expectations. To conduct my research, I evaluated undergraduate wildlife curricula offered by 42 accredited universities listed on the National Association of University Fisheries and Wildlife Programs. I compared their wildlife undergraduate curriculums to published OPM 0486 federal standards (OPM 0486 workforce guidelines) for educational requirements to qualify as a wildlife biologist. Concurrent to the curricula analysis, I surveyed state and federal wildlife agencies hiring supervisors to determine if recent hires possessed desired knowledge and skill-sets. Additionally, I emailed surveys to 38 undergraduate student chapters of The Wildlife Society to assess the students’ personal learning and professional goals and mentoring needs. Most university undergraduate wildlife programs may offer the coursework to meet OPM 0486 federal guidelines, but because of how the universities structure their curricula, students fail to fit the criteria. Additionally, many students expressed concerns that they are not receiving the mentoring they desire to prepare them for professional careers. Specific wildlife hiring supervisors included new hires did not have the proper hands-on skill-sets, human dimensions skills, communication skills, oral skills, leadership skills needed to succeed professionally. To address these gaps, I recommend that universities 1) update undergraduate wildlife course curricula, 2) create universal titles for wildlife courses that match the federal course list, and 3) build better partnerships with state and federal wildlife agencies to see what skill-sets they expect in new hires.

description: El Virus de la Tristeza de los Citricos (CTV) es la principal limitante de la producciôn citricola en la Repûblica Dominicana. En el periodo marzo a octubre del 2007 se realizaron muestreos en viveros y plantaciones comerciales para determinar el estatus actual del CTV. Se muestrearon nueve viveros tomando entre 1 y 2% del total de plantas para un total de 700 plantas muestreadas. A nivel de campo se muestrearon 42 plantaciones en 18 provincias del pais, tomando 3200 muestras. Se usaron bloques de 400 plantas con una configuraciôn de 20 hileras χ 20 plantas, tomando 100 muestras en cada uno. Seis diferentes cultivares fueron muestreados, los cuales fueron, naranjas dulces (cv. 'Valencia' y 'Washington Navel'), limon 'Persa', mandarinas, toronjas y limon 'Criollo' ('Lima Mexicana'). Se utilizô la técnica serolôgica de impresiôn directa del tejido (DTBIA) sobre membranas de nitrocelulosa de 0.45 μηι. Se usaron dos tipos de anticuerpos monoclonales, uno de los cuales (MCA-13) reconoce las razas severas y el otro compuesto de la mezcla de dos anticuerpos (3DF1-3CA5), que reconocen todas las razas del CTV. Los anälisis indican que siete de los nueve viveros muestreados reaccionaron a ambos anticuerpos, mientras que en las muestras de campo todas fueron positivas a ambos anticuerpos. Estos resultados muestran que el CTV esta ampliamente distribuido en las diferentes regiones productoras de citricos del pais. Los resultados de viveros presentan altos niveles de contaminaciôn, indicando que las fuentes de yemas utilizadas por los viveristas estân contaminadas. No hubo diferencias en los resultados entre los diferentes anticuerpos utilizados, por lo que las razas severas y no severas estân interactuando juntas en la citricultura dominicana.

description: This letter presents an improved discussion of the data provided in a recent article on EDTA removal from aqueous solutions using elemental iron (Fe0) by O. Gyliene and his co-workers. It is shown that the authors have furnished a brilliant validation of the concept that dissolved contaminants are primary removed in Fe0/H2O systems by adsorption onto iron corrosion products and co-precipitation with iron corrosion products. It is reiterated that contaminant removal and contaminant reduction should not be interchanged randomly.

description: The increasing interest in compact astrophysical objects (neutron stars, binaries, galactic black holes) has stimulated the search for rigorous methods, which allow a systematic general relativistic description of such objects. This paper is meant to demonstrate the use of the inverse scattering method, which allows, in particular cases, the treatment of rotating body problems. The idea is to replace the investigation of the matter region of a rotating body by the formulation of boundary values along the surface of the body. In this way we construct solutions describing rotating black holes and disks of dust ("galaxies"). Physical properties of the solutions and consequences of the approach are discussed. Among other things, the balance problem for two black holes can be tackled.

description: Corn and soybean meal, used in the diet of broiler chickens are expensive and they are imported commodities in the Dominican Republic. Therefore, feeding alternatives to these ingredients are needed in this country. Palm kernel cake (PKC) has shown to improved body weight and feed conversion of chickens, pig and cattle. However, it has not been evaluated in the Dominican Republic conditions. The objective of this study was to evaluate the effect of PKC on broiler performance and carcass yield at 43 days of age. Two separate trials were conducted using a total of 200 chicks per trial and the results were combined for the statistic analysis. These chicks were randomly distributed in five treatment groups (40 chicks/treatment group/trial). The treatment groups include a normal corn-soybean meal diet, which met or exceeded the nutritional requirements of NRC, 1994 or the same diet with 6%, 12%, 24% and 30% of PKC. Chickens were weighted weekly and the feed intake was registered daily. The feed intake for the whole period of the experiment (43 days) was significant higher at 6%, (3.04 ± 0.18 kg) 12% (3.38 ± 0.18 kg), 24% (3.63 ± 0.18 kg) and 30% (3.60 ± 0.18 kg) compared to PKC control diet (2.42 ±0.18 kg). The PKC treatments increased the daily weight gain (56.40 ± 1.06 g/d (from day 0 to 43) at 12 % compared to 0% (44.75 ± 1.06 g/d). The feed efficiency was improved at 6% PKC (79.34 ± 1.40) compared to 30% (62.14 ± 1.39). Carcass yield was not affected by the PKC levels. The data of the present study suggest that the addition of PKC in the diet of chicken may substitute the corn without affecting chicken performance; moreover, PKC may represent an alternative to reduce the cost in the poultry industry

description: Band bending at semiconductor surfaces induced by chemical doping or electric fields can create metallic surfaces with properties not found in the bulk, such as high electron mobility, magnetism or superconductivity. Optical generation of such metallic surfaces via BB on ultrafast timescales would facilitate a drastic manipulation of the conduction, magnetic and optical properties of semiconductors for high-speed electronics. Here, we demonstrate the ultrafast generation of a metal at the (10-10) surface of ZnO upon photoexcitation. Compared to hitherto known ultrafast photoinduced semiconductor-to-metal transitions that occur in the bulk of inorganic semiconductors, the metallization of the ZnO surface is launched by 3-4 orders of magnitude lower photon fluxes. Using time- and angle-resolved photoelectron spectroscopy, we show that the phase transition is caused by photoinduced downward surface band bending due to photodepletion of donor-type deep surface defects. At low photon flux, surface-confined excitons are formed. Above a critical exciton density, a Mott transition occurs, leading to a partially filled metallic band below the equilibrium Fermi energy. This process is in analogy to chemical doping of semiconductor surfaces. The discovered mechanism is not material-specific and presents a general route for controlling metallicity confined to semiconductor interfaces on ultrafast timescales.

description: The analysis "Evaluation of pathways for exotic plant pest movement into, within, and out of the Greater Caribbean Region", is a collaborative effort between the Caribbean Invasive Species Working Group (CISWG) and the United States Department of Agriculture (USDA). The objective of this analysis is to contribute to an improved understanding of pathways of exotic pest movement as they pertain to the Greater Caribbean Region, thereby helping CISWG to enhance or refine the Caribbean Regional Invasive Species Intervention Strategy (CRISIS) for preventing the introduction or spread of exotic pests. The scope of the pathway analysis includes nearly all countries bordering the Caribbean Sea and all terrestrial, non-vertebrate, plant pests. Among the pathways evaluated in the context of this analysis are: airline passenger baggage, international mail, people movement, maritime cargo, and wood packaging material. Some of these topics are discussed in other papers published in these proceedings.

For this purpose, the results of own research, secondary data from the Central Statistical Office and report on the state of small and medium-sized in Poland in 2013-2014 prepared by PARP as well as literature were used. The study shows that almost every other entrepreneur running a business to invest their own savings, and only one in four use the bank credit. The vast majority of entrepreneurs intend to further develop the company’s business activities. As the main barrier to doing business was high fees prescribed by law, which is compulsory payments to social insurance, taxes and stamp duties. Therefore, to simplify the burdensome regulations on starting and running a business is an important challenge for policy.

description: Multi-plane light conversion allows to perform arbitrary transformations on a finite set of spatial modes with no theoretical restriction to the quality of the transformation. Even though the number of shaped modes is in general small, the number of modes transmitted by a multi-plane light converter (MPLC) is extremely large. In this work, we aim to characterize the transmission properties of a multi-plane light converter inside and, for the first time, outside the design-modes subspace. By numerically reconstructing the transmission matrix of such systems, we individuate new ways to evaluate their efficiency in performing the design transformation. Moreover, we develop an analytical random matrix model that suggests that in the regime of a large number of shaped modes an MPLC behaves like a random scattering medium with limited number of controlled channels.

As a rat ages, autoresuscitation ability is lost during a transitional period ('developmental window') between 16 - 20 post-natal days (PND) so that hypothermic respiratory arrest results in death for a mature rat. Hamsters retain the ability to autoresuscitate past this developmental window. The retention of this ability in hamsters implies that there may be fundamental differences in the central rhythm generator (CRG) of rats and hamsters. This study tests the hypothesis that the contribution to respiratory rhythm generation of the putatively rhythmogenic persistent Na⁺ current (INaP) and Ca²⁺activated non-selective cation current (ICAN). two currents which may facilitate the initiation of breathing after arrest, is different between rats and hamsters. Because autoresuscitation ability is lost during development, we also test the hypothesis that the INaP and I CANcontribution to respiratory rhythm generation change as a rat ages. We applied riluzole (INaP blocker) and flufenamic acid (FFA; ICAN blocker) to the arterially perfused in situ working heart-brainstem preparation in hamsters and two age groups of rats (12 - 14 PND, >23 PND). Application of riluzole and FFA to rats and hamsters showed that elimination of INaP and ICAN resulted in profound decrease in phrenic burst frequency in hamsters with little change in rats. This result is consistent with the hypothesis that a phylogenetic difference exists in the mechanism of setting respiratory rhythm in the CRG of rats and hamsters. Comparisons between young and weaned rats showed that young rats tended to be more sensitive to the application of riluzole and FFA than weaned rats. The small differences observed between young and weaned rats in the reliance on INaP and ICAN for respiratory rhythm generation are consistent with the hypothesis that a developmental change occurs in the CRG of rats during maturation. Increasing the proportion of CO₂ that the preparations were exposed to increased neural ventilation in weaned rats suggesting that INaP and ICAN provide a source of excitatory drive to the CRG.

description: Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga Dresser Formation (Pilbara Craton, Western Australia). Catalytic hydropyrolysis (HyPy) of this kerogen yielded n-alkanes up to n-C22, with a sharp decrease in abundance beyond n-C18. This distribution ( n-C18) is very similar to that observed in HyPy products of recent bacterial biomass, which was used as reference material, whereas it differs markedly from the unimodal distribution of abiotic compounds experimentally formed via Fischer–Tropsch-type synthesis. We therefore propose that the organic matter in the Archaean chert veins has a primarily microbial origin. The microbially derived organic matter accumulated in anoxic aquatic (surface and/or subsurface) environments and was then assimilated, redistributed and sequestered by the hydrothermal fluids (“hydrothermal pump hypothesis”)

description: The solid-state polymorphism of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, [bmim][PF6], has been investigated via low-temperature and high-pressure crystallisation experiments. The samples have been characterised by single-crystal X-ray diffraction, optical microscopy and Raman spectroscopy. The solid-state phase behaviour of the compound is confirmed and clarified with respect to previous phase diagrams. The structures of the previously reported g-form, which essentially exhibits a G0T cation conformation, as well as those of the elusive b- and a-forms, are reported. Crystals of the bphase are twinned and the structure is heavily disordered; the cation conformation in this form is predominantly TT, though significant contributions from other less frequently encountered conformers are also observed at low temperature and high pressure. The cation conformation in the a-form is GT; the presence of the G0T conformer at 193 K in this phase can be eliminated on cooling to 100 K. Whilst X-ray structural data are overall in good agreement with previous interpretations based on Raman and NMR studies, they also reveal a more subtle interplay of intermolecular interactions, which give rise to a wider range of conformers than previously considered.

description: Paper in honour of Freeman Dyson on the occasion of his 80th birthday. Normal N-body systems relax to equilibrium distributions in which classical kinetic energy components are 1/2 kT, but, when inter-particle forces are an inverse cubic repulsion together with a linear (simple harmonic) attraction, the system pulsates for ever. In spite of this pulsation in scale, r(t), other degrees of freedom relax to an ever-changing Maxwellian distribution. With a new time, tau, defined so that r^2d/dt =d/d tau it is shown that the remaining degrees of freedom evolve with an unchanging reduced Hamiltonian. The distribution predicted by equilibrium statistical mechanics applied to the reduced Hamiltonian is an ever-pulsating Maxwellian in which the temperature pulsates like r^-2. Numerical simulation with 1000 particles demonstrate a rapid relaxation to this pulsating equilibrium.

description: The origin and possible antiquity of the spectacularly diverse modern deep-sea fauna has been debated since the beginning of deep-sea research in the mid-nineteenth century. Recent hypotheses, based on biogeographic patterns and molecular clock estimates, support a latest Mesozoic or early Cenozoic date for the origin of key groups of the present deep-sea fauna (echinoids, octopods). This relatively young age is consistent with hypotheses that argue for extensive extinction during Jurassic and Cretaceous Oceanic Anoxic Events (OAEs) and the mid-Cenozoic cooling of deep-water masses, implying repeated re-colonization by immigration of taxa from shallow-water habitats. Here we report on a well-preserved echinoderm assemblage from deep-sea (1000–1500 m paleodepth) sediments of the NE-Atlantic of Early Cretaceous age (114 Ma). The assemblage is strikingly similar to that of extant bathyal echinoderm communities in composition, including families and genera found exclusively in modern deep-sea habitats. A number of taxa found in the assemblage have no fossil record at shelf depths postdating the assemblage, which precludes the possibility of deep-sea recolonization from shallow habitats following episodic extinction at least for those groups. Our discovery provides the first key fossil evidence that a significant part of the modern deep-sea fauna is considerably older than previously assumed. As a consequence, most major paleoceanographic events had far less impact on the diversity of deep-sea faunas than has been implied. It also suggests that deep-sea biota are more resilient to extinction events than shallow-water forms, and that the unusual deep-sea environment, indeed, provides evolutionary stability which is very rarely punctuated on macroevolutionary time scales.

description: Knowledge Graphs (KG) allow to merge and connect heterogeneous data despite their differences; they are incomplete by design. Yet, KG data producers need to ensure the best level of completeness, as far as possible. The difficulty is that they have no means to distinguish cases where incomplete entities could and should be fixed. We present a new visualisation tool: The Missing Path, to support them in identifying coherent subsets of entities that can be repaired. It relies on a map, grouping entities according to their incomplete profile. The map is coordinated with histograms and stacked charts to support interactive exploration and analysis; the summary of a subset can be compared with the one of the full collection to reveal its distinctive features. We conduct an iterative design process and evaluation with 9 Wikidata contributors. Participants gain insights and find various strategies to identify coherent subsets to be fixed.

description: The article discusses the issues of agricultural risk management in Turkey, where since 2006 new system of government-private partnership of agricultural insurance has been practiced. The aim of this paper is to indicate the most essential system’s elements from legal and economic point of view. The paper is based on a dogmatic analysis of normative texts and a descriptive method. It also refers to Polish and foreign books on the subject. The conducted research allows to state that the risks management tools are similar to EUs’ ones, even not all them are implemented. From the practical point of view, the tools’ unification within TARSIM – the public-private partnerships is an achievement
Airborne Thermal Data Identifies Groundwater Discharge at the North-Western Coast of the Dead Sea

description: A qualitative and quantitative monitoring of groundwater discharge was conducted based on an airborne thermal campaign undertaken along the north-western coast of the Dead Sea in January 2011 to contribute to the relatively scarce information on groundwater discharge to date in the region. The application of airborne thermal data exploits thermal contrasts that exist between discharging groundwater and background sea surface temperatures of the Dead Sea. Using these contrasts, 72 discharge sites were identified from which only 42 were known from previous in situ measurements undertaken at terrestrial springs by the Israel Hydrological Service. Six of these sites represent submarine springs and at a further 24 locations groundwater appears to seep through the sediment. Although the abundance of groundwater seepage sites suggests a significant, but so far unknown groundwater source, the main contribution appears to originate from terrestrial springs. In an attempt to provide a quantitative approach for terrestrial springs, a linear bootstrap regression model between in situ spring discharge and respective thermal discharge plumes (r2 = 0.87 p < 0.001) is developed and presented here. While the results appear promising and could potentially be applied to derive discharge values at unmonitored sites, several influence factors need to be clarified before a robust and reliable model to efficiently derive a complete quantitative picture of groundwater discharge can be proposed.

description: We report optical absorption imaging of ultracold neutral plasmas.Images are used to measure the ion absorption spectrum, which is Doppler-broadened. Through the spectral width, we monitor ion equilibration in the first 250ns after plasma formation. The equilibration leaves ions on the border between the weakly coupled gaseous and strongly coupled liquid states. On a longer timescale of microseconds, we observe radial acceleration of ions resulting from pressure exerted by the trapped electron gas.
