Microscopics diagnostic difficulties and the role of amanitin determination in poisoning caused by Amanita phalloides

Abstract Introduction: The consumption of mushrooms (Basidiomycota) in Poland is one of the highest in Europe. It is particularly high in the 3rd quarter of each year, which is accompanied by an increase in the number of mushroom poisonings. This study aims to present difficulties with microscopic identification, the most popular method for diagnosing mushroom poisoning in hospital settings, when it comes to detecting Amanita phalloides spores in biological material. Materials and methods: Spore analysis was carried out using aqueous solutions containing reference spores of different mushrooms: death cap (Amanita phalloides), parasol mushroom (Macrolepiota procera), field mushroom (Agaricus campestris), yellow knight mushroom (Tricholoma equestre), and green cracking russula (Russula virescens). The spore analysis was also carried out for a meal (soup) containing selected spores. Spores were identified using a light microscope and staining with Sudan III and Meltzer’s reagent. A statistical analysis of mushroom poisoning cases was also performed at the Department of Clinical and Forensic Toxicology, Pomeranian Medical University in Szczecin using records for 2015–2019. Conlusions: Analysis of data from 2015–2019 from the Department of Clinical and Forensic Toxicology at the Pomeranian Medical University in Szczecin showed a marked increase in mushroom poisoning cases in the 3rd quarter of each year. Analysis of materials containing Amanita phalloides spores revealed their high similarity to oil drops and other cell structures present in biological material, resulting in the low reliability of microscopic identification. Therefore, as the absence of Amanita phalloides spores in the tested biological material does not rule out poisoning with this mushroom, a more advanced instrumental analysis (ELISA, LC/MS) is recommended.
High Performance Simulation of Free Surface Flows Using the Lattice Boltzmann Method

Continuing increases in computing power open the discipline of computer simulation to more and more complex applications. One example is the simulation of free surface flows. Thies, Körner et al. proposed a model to simulate such flows in the context of material science. However, their model is limited to two spatial dimensions. One major topic of the work presented in this thesis is the extension of their model to 3D. Various modifications to the algorithms are described in detail. In particular, the calculation of the surface curvature required a completely different approach which is now based on a local triangulation of the fluid/gas interface. As the second major topic of this thesis, various aspects of high performance computing are discussed on the basis of the implementation of the 3D model. An example is the optimization of the spatial and temporal data locality which is difficult due to the complexity of this model. Furthermore, different optimization strategies for parallel computing are discussed in detail. The application of the presented performance optimizations is not limited to this specific model implementation, but can be generalized to a wide range of complex simulation codes.

Onset Detection of Pulse-Shaped Bioelectrical Signals Using Linear State Space Models

Abstract Bioelectrical signals are often pulse-shaped with superimposed interference signals. In this context, accurate identification of features such as pulse onsets, peaks, amplitudes, and duration is a frequent problem. In this paper, we present a versatile method of rather low computational complexity to robustly identify such features in real-world signals. For that, we take use of two straight-line models fit to the observations by minimizing a quadratic cost term, and then identify desired features by tweaked likelihood measures. To demonstrate the idea and facilitate access to the method, we provide examples from the field of cardiology.
Interannual and Interdecadal Variations of the Western North Pacific Monsoon and Baiu Rainfall and t

Interannual and interdecadal variations of the Western North Pacific Monsoon (WNPM) and the East Asian Baiu rainfall are analyzed using 30-year (1963-1992) daily sea-level pressure, 30-year monthly and daily rainfall data for the East Asia, and 15-year (April 1978-December 1992) 5-day mean 1-degree latitude-longitude gridded GMS high-cloud-amount data. The relationship to the El Nino-La Nina cycles are investigated by using monthly sea surface temperatures (SST) data over a region defined by 4°N-4°S, 150°W-90°W in the equatorial Eastern Pacific (NINO3 SST) for a 30-year period from 1963 to 1992. An analysis of interannual variations in intensity of the WNPM in late July shows high negative correlations with the NINO3 SST during a recent 15-year period from 1978 to 1992. In the La Nina (El Nino) years, strong (weak) WNPM are observed. For the Baiu rainfall, high positive correlations with the NINO3 SST are observed in July during this period. In the La Nina (El Nino) years, light (heavy) Baiu rainfall is observed. These correlations are the results of a delay of about 20 days in the onset dates of the WNPM and the peak dates of the Baiu rainfall between the La Nina and El Nino years. In the La Nina years, the early onset of the WNPM and early peak of the Baiu rainfall are observed. In the El Nino years, the late onset of the WNPM and late peak of the Baiu rainfall are observed. The Baiu rainfall also shows a high positive correlation with the NINO3 SST during the early 15-year period from 1963 to 1977. However, difference in the dates of peak of the Baiu rainfall between the La Nina and El Nino years are smaller. An analysis of the lag-correlations among the WNPM, the Baiu rainfall and the NINO3 SST shows that the SST leads the WNPM by 1 to 2 months. On the other hand, the Baiu rainfall leads (lags) the SST by 3 (2) months during a recent (early) 15-year period from 1978 to 1992 (1963 to 1977). An autocorrelation analysis of the NINO3 SST shows that the biennial oscillation mode was pronounced during a 15-year period from 1963 to 1977. In a recent 15-year period, the low-frequency mode was dominant. These changes in the periods of the SST oscillations may be related to the recent increase in the correlations among the NINO3 SST and the WNPM and Baiu rainfall.
MHD equilibria of astrospheric flows

The hot gas cavities around stars which have a stellar wind are called astrospheres. Between the outer interstellar medium and the stellar wind there forms a contact surface or boundary surface which is called an astropause. In this thesis the geometrical shape of such an astrosphere/astropause region is calculated consistently together with the flow and magnetic fields, which occur in the interstellar medium and the stellar wind. It is also analyzed how this boundary surface becomes leaky due to finite resistivity effects, including the breakdown of magnetic field freezing (magnetic reconnection).
Phase-resolved Spectroscopy of the Crab Pulsar with XMM-Newton

The Crab pulsar (PSR B0531+21) has been observed with the EPIC-pn camera on board the ESA XMM-Newton satellite. The high time resolution of the EPIC camera (7 J-ts) in its special Burst mode in combination with the huge effective area and the high quantum efficiency of the pn-CCD allows phase resolved spectroscopy of good quality over the energy range 0.6-8.5 keY. We performed phase resolved spectroscopy of the modulated flux of the Crab pulsar and found a significant hardening of the photon index in the inter-pulse region. Also the second pulse is harder in index by 0.1 than the first pulse.
Measurements of neutron-induced fission cross sections for Bi209,Pbnat,Pb208,Au197,Wnat, and Ta181 in the intermediate energy region

Neutron-induced fission cross-section ratios natPb∕209Bi, 208Pb∕209Bi, 197Au∕209Bi, natW∕209Bi, 181Ta∕209Bi, and 209Bi∕238U have been measured in the 30–180 MeV energy range using the neutron beam facility at The Svedberg Laboratory in Uppsala. The 7Li(p,n) reaction was employed as a neutron source. The fission fragments were detected by thin-film breakdown counters. Cross sections at specific energies were determined using unfolding techniques with respect to the excitation function and the neutron spectra, the latter obtained from recent measurements and an evaluation. The absolute fission cross sections were obtained using the standard 238U(n,f) cross section. The natW(n,f) and 181Ta(n,f) cross sections have been measured for the first time. The results for 209Bi(n,f), natPb(n,f), 208Pb(n,f), and 197Au(n,f) cross sections have been compared with available literature data. A universal easy-to-use parametrization has been suggested for all measured cross sections. The common features of subactinide neutron-induced fission cross sections are found to be similar to those of the proton-induced fission data.
Bi2Sr2Co2Oy whiskers with high thermoelectric figure of merit

Bi2Sr2Co2Oy (BC-222) whiskers were grown with an excellent Seebeck coefficient (S) and electrical resistivity (ρ) for power generation applications at high temperatures in air. The S value of these long BC-222 whiskers reached almost 300 μV K−1 at 973 K. Thermal conductivity (κ) was measured and found to be suppressed to a low value of about 2.0 W m−1 K−1. This is considered due not only to a phonon–phonon interaction but also other scattering processes. The resulting dimensionless thermoelectric figure of merit ZT(=S2T/ρκ) was more than 1.1, which corresponds to a conversion efficiency of almost 10% at 973 K in air.
Interception and Rendezvous Between Autonomous Vehicles

The problem of pursuit and evasion is a classic problem that has intrigued mathematicians for many generations. Suppose a target or evader is moving along a given curve in the plane. A pursuer or chaser is moving such that its line of sight is always pointing towards the target. The classic problem is to determine the trajectory of the pursuer such that it eventually captures the target. There is extensive literature on this problem, see for example the recent book by Nahin (Nahin, 2007). A special case of the pursuit problem is the case where the curve of the target is a circle. This is a classic problem which was first treated by Hathaway (Hathaway, 1921), see also the book by Davis (Davis, 1962). In the classic problems, the line of sight is always pointing towards the target. This method of pursuit is also known as 'pure pursuit' or 'dog pursuit' or 'courbe de chien' in French. Although there have been some modern works on extensions of the classic problem of pursuit, see for example (Marshall, 2005), here we completely abandon the 'pure pursuit' restriction and we treat the problem where the pursuer is required to capture or intercept the target in a given prescribed time or in minimum time. Also, in the classic problem, the velocities of the target and pursuer are assumed constant and there is no consideration of the physics of the motion, such as thrust forces, hydrodynamic or aerodynamic drag and other forces that might be acting on the target and pursuer. In an active-passive rendezvous problem between two vehicles, the passive or target vehicle moves passively along its trajectory. The active or chaser vehicle is controlled or guided such as to meet the passive vehicle at a later time, matching both the location and the velocity of the target vehicle. An interception problem is similar to the rendezvous problem, except that there is no need to match the final velocities of the two vehicles. On the other hand, in a cooperative rendezvous problem, the two vehicles are active and maneuver such as to meet at a later time, at the same location with the same velocity. The two vehicles start the motion from different initial locations and might have different initial velocities. An optimal control problem consists of finding the control histories, i.e., the controls as a function of time, and the state variables of the dynamical system such as to minimize a performance index. The differential equations of motion of the vehicles are treated as dynamical constraints. One possible approach to the solution of the rendezvous problem is to formulate it as an optimal control problem in which one is seeking the controls such as to

Checking the potassium origin of the new emission line at 3.5 keV using the K xix line complex at 3.7 keV

Whether the new line at ~3.5 keV, recently detected in different samples of galaxy clusters, Andromeda galaxy and central part of our Galaxy, is due to Potassium emission lines, is now unclear. By using the latest astrophysical atomic emission line database AtomDB v. 3.0. 2, we show that the most prospective method to directly check its Potassium origin will be the study of K XIX emission line complex at ~3.7 keV with future X-ray imaging spectrometers such as Soft X-ray spectometer on-board Astro-H mission or microcalorimeter on-board Micro-X sounding rocket experiment. To further reduce the remaining (factor ~3-5) uncertainty of the 3.7/3.5 keV ratio one should perform more precise modeling including removal of significant spatial inhomogeneities, detailed treatment of background components, and further extension of the modeled energy range.
Dielectronic recombination of Fe22+ and Fe21+

The author calculates dielectronic recombination rate coefficients for the Be-like and B-like ions Fe22+ and Fe21+ using a multiconfiguration LS-coupling expansion and allowing for Delta nc=0 and Delta nc=1 autoionising transition into the continuum of excited states. The effect of intermediate coupling is also investigated and found to be less than 10%. They use autostructure-a general program for the calculation of multiconfiguration LS-coupling or intermediate-coupling autoionisation transition rates (incorporating superstructure)-to calculate the dielectronic recombination rate coefficient for the 1-2 and 2-3 core transitions. Together with the Burgess general formula for the 2-2 transition, they obtain about 95% of the total dielectronic recombination rate coefficient for ground state and look at its effect on the ionisation balance for a steady-state plasma. They confirm the recent findings of Smith et al. (1985) that the effect of Delta nc=0 secondary autoionisation is much less significant for highly charged ions than was suggested by Jacobs et al.
Relativistic Quantum Mechanics And Quantum Fields

A sequel to the well received book, Quantum Mechanics by T Y Wu, this book carries on where the earlier volume ends. This present volume follows the generally pedagogic style of Quantum Mechanics. The scope ranges from relativistic quantum mechanics to an introduction to quantum field theory with quantum electrodynamics as the basic example and ends with an exposition of important issues related to the standard model. The book presents the subject in basic and easy-to-grasp notions which will enhance the purpose of this book as a useful textbook in the area of relativistic quantum mechanics and quantum electrodynamics.
Some difficulties with some posterior probability approximations

n Scott (2002) and Congdon (2006), a new method is advanced to compute posterior probabilities of models under consideration. It is based solely on MCMC outputs restricted to single models, i.e., it is bypassing reversible jump and other model exploration techniques. While it is indeed possible to approxi- mate posterior probabilities based solely on MCMC outputs from single models, as demonstrated by Gelfand and Dey (1994) and Bartolucci et al. (2006), we show that the proposals of Scott (2002) and Congdon (2006) are biased and advance sev- eral arguments towards this thesis, the primary one being the confusion between model-based posteriors and joint pseudo-posteriors. From a practical point of view, the bias in Scott's (2002) approximation appears to be much more severe than the one in Congdon's (2006), the latter being often of the same magnitude as the posterior probability it approximates, although we also exhibit an example where the divergence from the true posterior probability is extreme.
Calculation of unsteady subsonic aerodynamic characteristics by means of the doublet lattice method

A method is desoribed for calculating the aerodynamic loading on nonplanar, infinitely thin, harmonically oscillating airfoils in subsonic flow as originally developed by Albano, Redden, Qiesing and Kalman. The generalized aerodynamic force coefficients are determined from the calculated pressure distributions. Because of the flexibility of the method, arising from the use of loading elements, it can be applied to a wide range of configurations including e.g. T-tails and biplanes.
RECIPROCAL CONTINUITY AND COMMON FIXED POINTS OF NONSELF MAPPINGS

We extend the notions of reciprocal continuity and $C_q$-commutativity to nonself setting besides observing equivalence between compatibility and $\phi$ -compatibility, and utilize the same to obtain some results on coincidence and common fixed points for two pairs of nonself mappings in metrically convex metric spaces. As an application of our main result, we also prove a common fixed point theorem in Banach spaces besides furnishing several illustrative examples.
Entrepreneurial Marketing and Performance of Insurance Firms in Kenya

Kenyan Ethiopia lags with a penetration rate of 0.40%. Poor standards of living have lowered the affordability of insurance Abstract: Economic and social resilience as well depends upon a robust and stable insurance industry. Its penetration in the globally is a cause for concern, with an unstable rate of below 10%. The Kenyaninsuranceindustryisso fragmented with 58 firms and just 5 of them wththeir market share suffiicient to competeglobally. Studies done globally and locally in other sectors of the economy have shown a positive relationship between entrepreneurial marketing (EM) and the performance . This study evaluated the effect of EM variables on the gross premium and market share as a performance indicators for insurance firms in Kenya. Specifically, the study determined the effect of: strategic orientation (differentiation strategy, cost leadership, customer orientation) innovation orientation (product innovation, processes innovation, market innovation), and innovation orientation (product, process and market) on the performance of the firms. Further, the effect of market orientation (frequency of market surveys and budget for market research) and resource leveraging (human resources and partnership and alliances) on the performance was analysed . Resultsindicated that strategic orientation had a positive but insignificant effect on the performance, while innovation, market orientation and resource leveraging had a positive and significant effect on the performance of insurance firms in Kenya. The study also established a negative but significant moderating effect of the regulatory framework (capitalization and licensing) on the relationship between EM and the performance of insurance firms in Kenya. Conclusion was reached that insurance firms should always consider the four dimensions of entrepreneurial marketing if they are to improve their performance.
Child welfare workers' perspectives on father-daughter attachments and teenage pregnancy

The study investigated Children and Family Services (CFS) workers' awareness of the importance of father­ daughter attachments and the associated risks of teenage pregnancy as well as the use of such knowledge in their intake assessment process. A quantitative, cross-sectional, survey design was utilized to study 113 CFS workers. The study found that CFS workers were familiar with father­ daughter attachments and their importance during the intake process. However, very few workers actually implemented that knowledge when creating case plans and intake assessments. Also, CFS workers were unaware of the affects that broken father-daughter attachments had on risk factors for teenage pregnancy. The study recommended that CFS workers should receive trainings on father-daughter attachments and risk factors for teenage pregnancy as well as the importance for implementation in intake assessments and case plans. Further research was recommended to evaluate whether implementation of the knowledge by CFS workers in the case plans enhances father-daughter relationships and ultimately decreases their risk for
Polynyas: Polar Physics Revealed through Visualization of the E3SM Global Climate Model

: Polynyas are openings within polar sea ice pack formed and sustained by atmospheric and oceanic processes. They occur in the Arctic ocean and the Southern ocean, lasting for many months, and act as a conduit for heat and water between the oceanic and atmospheric systems. Realistic coastal and open ocean polynyas in global climate models are a stringent test of the model’s physical fidelity, as their formation depends on complex interactions between the sea ice, ocean, and atmosphere. In this video we highlight the role of polynyas in modulating earth’s mesoscale processes using high-resolution simulations from the Energy Exascale Earth System Model (E3SM). A team of climate modelers, an artist, and a computer science specialist collaborated to generate animations that visualize these large data sets. The detailed overlay of variables, dense in time and space, provided climate scientists with new insights into their research — especially in regards to the dynamics of convective plumes driven by cold melt water near open ocean polynyas, and the katabatic winds that create coastal polynyas at the edge of Antarctica.
