Agonimia pacifica

description: Agonimia pacifica (Harada) Diederich
 Harada (1993) described this species and placed it in a new genus Agonimiella. Diederich however convincingly showed that the differences between the new genus and Agonimia are more minor than thought by Harada (Aptroot et al. 1997). Consequently he transferred the species to the genus Agonimia. Our own observations confirmed those of Diederich. Previously, Agonimia pacifica was known from Brazil, Costa Rica, Japan, Reunion and Taiwan (Aptroot 2002, Aptroot et al. 2008, v.d. Boom et al. 2011). This report is a new addition to the Chinese lichen biota.

description: Studies combining psychotherapy with psychedelic drugs (PsiDs) have demonstrated positive outcomes that are often associated with PsiDs' ability to induce 'mystical-type' experiences (MTEs) - i.e., subjective experiences whose characteristics include a sense of connectedness, transcendence, and ineffability. We suggest that both PsiDs and virtual reality can be situated on a broader spectrum of psychedelic technologies. To test this hypothesis, we used concepts, methods, and analysis strategies from PsiD research to design and evaluate 'Isness', a multi-person VR journey where participants experience the collective emergence, fluctuation, and dissipation of their bodies as energetic essences. A study (N=57) analyzing participant responses to a commonly used PsiD experience questionnaire (MEQ30) indicates that Isness participants had MTEs comparable to those reported in double-blind clinical studies after high doses of psilocybin & LSD. Within a supportive setting and conceptual framework, VR phenomenology can create the conditions for MTEs from which participants derive insight and meaning.
Flat Topological Bands and Eigenstate Criticality in a Quasiperiodic Insulator

description: The effects of downfolding a Brillouin zone can open gaps and quench the kinetic energy by flattening bands. Quasiperiodic systems are extreme examples of this process, which leads to new phases and critical eigenstates. We analytically and numerically investigate these effects in a two dimensional topological insulator with a quasiperiodic potential and discover a complex phase diagram. We study the nature of the resulting eigenstate quantum phase transitions; a quasiperiodic potential can make a trivial insulator topological and induce topological insulator-to-metal phase transitions through a unique universality class distinct from random systems. This wealth of critical behavior occurs concomitantly with the quenching of the kinetic energy, resulting in flat topological bands that could serve as a platform to realize the fractional quantum Hall effect without a magnetic field.

description: This study assessed the effectiveness of the experimental approach "Unified, Conceptual, Integrated Model (U.C.I.M.) for English Grammar" for increasing the skills of a sample of adult learners in elements of standard written English as defined and measured through the "Usage" (assessing use of pronouns and modifiers) and "Sentence Structure" (assessing complete sentence use, appropriate use of subordination and coordination, appropriate modifier placement) subtests of the Descriptive Tests of Language Skills (DTLS). Two hypotheses guided the development of the study: (a) the mean DTLS "Usage" subtest scores and (b) the mean DTLS "Sentence Structure" subtest scores for the study sample taught by the experimental approach would be significantly higher than those of a comparison group taught by a traditional approach. The study followed a quasi-experimental pretest-posttest design, involving experimental (N = 202) and comparison (N = 238) groups. The homogeneity of the groups was established through a chi-square test of difference on selected demographic characteristics. The subjects participated in seven weeks of instruction (ten hours) in standard applied, English grammar. The Traditional group was treated with a "traditional" model constructed by the writer, based on analyses of 32 texts and other materials, which revealed the model as generally authoritative, rule-based, and characterized by fragmentation and variability in content, presentation, and learning sequence. The Experimental group was treated with the concept-based "Unified, Conceptual, Integrated Model for English Grammar" approach devised by the author. Hypothesis testing utilizing pre- and posttest data entailed the t-test statistic. Significance was set at p $<$.05. The results of hypothesis testing led to the rejection of both hypotheses. The Experimental group did not show a significant gain. The data did show greater gains for the experimental group in the parts of the tests that assess communicative areas. The findings warrant the conclusions that the U.C.I.M., as conducted under the conditions of this study, is not significantly more effective than the traditional model, that no definitive changes in approach should be made as a result of this study, but that, from the findings of the subtest cluster scores, selected aspects of the U.C.I.M. concerned with linguistic connectivity may have significance for teaching models.

description: The aim of the study is to identify the different impacts of the economy and agriculture on the environment in the different countries in natural, historical, political and economic terms. Two countries were chosen as an example – the USA and China, and one group of countries – the European Union. The research used data from Faostat and the World Bank. It also used the author’s method of estimation of agricultural production, defined as the amount of energy expressed in kilocalories. Research showed that highly developed economies are highly polutogenic, but, on the other hand, they are effective, which means that the production of GDP entails relatively little pollution. In the case of agriculture, it was stated that productivity is determined primarily by demographic factors, mainly the density of population. It means that despite the differences in the level of development, the productivity of land is relatively high in China and the EU and lower in the USA. Basing on the analyses, a number of development dilemmas were pointed out, highlighting the social importance of multi-faceted security generated by the developed economy. At the same time, environmental threats were also identified.
A Cellular Automaton Model for the Traffic Flow in Bogota

Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In this work we propose a car cellular automaton model that reproduces the experimental behavior of traffic flows in Bogotá. Our model includes three elements: hysteresis between the acceleration and brake gaps, a delay time in the acceleration, and an instantaneous brake. The parameters of our model were obtained from direct measurements inside a car on motorways in Bogotá. Next, we simulated with this model the flux-density fundamental diagram for a single-lane traffic road and compared it with experimental data. Our simulations are in very good agreement with the experimental measurements, not just in the shape of the fundamental diagram, but also in the numerical values for both the road capacity and the density of maximal flux. Our model reproduces, too, the qualitative behavior of shock waves. In addition, our work identifies the periodic boundary conditions as the source of false peaks in the fundamental diagram, when short roads are simulated, that have been also found in previous works. The phase transition between free and congested traffic is also investigated by computing both the relaxation time and the order parameter. Our work shows how different the traffic behavior from one city to another can be, and how important is to determine the model parameters for each city.

description: The goal of the research is to estimate the level of risk of agricultural companies according to degree of operating and financial leverage, and to define relations between these measures and ratios of financial efficiency. The research involved companies from the database of the Institute of Agricultural and Food Economics – National Research Institute in 2005-2013. The greatest impact on risk of agricultural companies had the degree of operating leverage characterizing sensitivity of operating profit on volatility of operating revenue, regarding to cost structure. The degree of financial leverage showing the level of debt and interest paid influenced the risk of agricultural companies to a lesser extent. Agricultural companies with a high degree of total leverage had lower financial efficiency, arising from a low ability to generate operating profit.

description: Along with the socio-economic development, agriculture has a natural tendency to increase productivity. Its effect is unfavourable for farmers agricultural overproduction. In this situation, the relatively constant food needs of individual societies are able to be met by an ever smaller number of farms. Prices of agricultural products show a declining trend, which at constant or rising costs incurred by farmers leads to the unfavourable phenomenon of opening of price scissors. Under such circumstances, a growing percentage of households are at risk of bankruptcy. Among farmers, there is even more pressure to improve productivity perceived individually as a way to improve the financial situation of the farm. This is how the vicious circle closes, because further productivity growth will result in even lower prices in the future. In the struggle against overproduction and its consequences, governments decide to subsidize agricultural prices, agricultural income, set production quotas or adopt set-aside policies. This paper asseses the effects of these forms of intervention on cereal producers activity, using the system dynamics method of Bossel (2007). The presented model is a great simplification of the reality, but it allows us to make interesting observations. It provides a multi-faceted look at the social costs and benefits of selected agricultural policy instruments.

description: We present circular and linear cross-correlation tests and the "friend-of-friend" analysis for phases of the Internal Linear Combination Map (ILC) and the WMAP foregrounds for all K--W frequency bands at the range of multipoles $\ell\le100$. We compare also Tegmark, de Oliveira-Costa and Hamilton (2003) and Naselsky et al. (2003) cleaned maps with corresponding foregrounds. We have found significant deviations from the expected Poissonian statistics for all the cleaned maps and foregrounds. Our analysis shows that, for a low multipole range of the cleaned maps, power spectra contains some of the foregrounds residuals mainly from the W band.

Data was obtained with the SLAC 8 GeV spectrometer at electron scattering angles between 15$\sp\circ$ and 90$\sp\circ$ and momenta between 0.5 and 7.5 GeV. Data was taken simultaneously in the SLAC 1.6 GeV spectrometer which was fixed at 90$\sp\circ$ and detected scattered electrons with momenta between 0.5 and 0.8 GeV. Experimental cross sections are presented for $Q\sp2=1.75$ to 4.00 (GeV/c)$\sp2$ as well as the separated longitudinal and transverse components, $R\sb{L}$ and $R\sb{T}.$ Neutron electromagnetic form factors were extracted from the separated $R\sb{L}$ and $R\sb{T}$ spectra using a PWIA model of the quasielastic peak. Sensitivity to deuteron wave function models and relativistic corrections are examined. The extracted neutron form factors are compared with various predictions and fits to previous data. Cross sections for electron-aluminum scattering in the 8 GeV spectrometer are reported with the extracted structure function, $\nu W\sb2,$ and the ratio of longitudinal to transverse cross sections, R.

 Sicut Coniocarpon cinnabarinum DC. sed thallo isidiis coralloideis instructo et ascosporis minoribus differt.
 Type:— VENEZUELA. Aragua: Parque Nacional Henry Pittier, 12 km along the road from Maracay to Ocumare de la Costa; Estacion Biologica Dr. Alberto Fernandez Y. Along the „Andrew Field trail“, in an old tropical mountain rainforest (selva nublada), 1100–1200 m, 10°21’ N, 67°40’ W, 2 August 2010, K. Kalb & J. Hernández (holotype VEN, isotype hb. Kalb 38476).
 Etymology:—The specific epithet refers to the coralloid outgrowths on the thallus.
 Thallus corticolous, delimited by a fluffy reddish-brown line, off-white or pale grey, surface smooth with purple-red coralloid outgrowths. Apothecia rare, 0.2–0.3 mm diam., flat to slightly concave, rounded, ± polygonal or linear, disc purple-brown, densely white pruinose, margins thick with a dark purple-red pruina, KOH+ purple, dissolving. Epihymenium brown, KOH-. Hymenium 70 µm high, hyaline; subhymenium 20 µ m. Asci clavate, 8-spored, 60 × 20 µ m. Ascospores 18–20 × 7–8 µ m, oblong-ovoid, colourless, old ascospores brownish. Chemistry: two unknown violet to red pigments with relative R f -values 11, 7, 6 (major) and 16, 3, 7 (minor) in solvents A, B’, C (Elix & Ernst-Russell 1993).
 Notes:—The major pigment in Coniocarpon coralloideum is also present as a minor metabolite in Coniocarpon cinnabarinum sensu lato, the minor pigment as a trace amount together with other pigments. The following two specimens were tested by TLC: K. Kalb: Lichenes neotropici 201, distributed as Arthonia tumidula (Ach.) Ach. from Mexico / Chiapas (hb. Kalb s.n.) and Coniocarpon cinnabarinum from Austria / Styria (hb. Kalb 806). It should be noted that the two samples differ slightly in their chemistry insofar that the Mexican specimen contains four rather than three pigments observed in the Austrian material. The new species seems to be widely distributed in the Neotropics, but as it is usually sterile it has not been collected or remains unidentified in herbaria.
 Additional material examined:— ECUADOR. Napo: Muyuna near Tena; in the garden of Establo de Tomas, at the base of an old deciduous tree, 550 m, 0°58’00’’ S, 77°51’30’’ W, 3–4 September 2011, K. Kalb & H. Jonitz (hb. Kalb 38962).

description: In this paper, a hybrid Lagrangian-Eulerian topology optimization (LETO) method is proposed to solve the elastic force equilibrium with the Material Point Method (MPM). LETO transfers density information from freely movable Lagrangian carrier particles to a fixed set of Eulerian quadrature points. This transfer is based on a smooth radial kernel involved in the compliance objective to avoid the artificial checkerboard pattern. The quadrature points act as MPM particles embedded in a lower-resolution grid and enable a sub-cell multi-density resolution of intricate structures with a reduced computational cost. A quadrature-level connectivity graph-based method is adopted to avoid the artificial checkerboard issues commonly existing in multi-resolution topology optimization methods. Numerical experiments are provided to demonstrate the efficacy of the proposed approach.

description: Fatty acid distributions are routinely studied by organic geochemists as they provide insight into the origins and processes involved in the transformation of organic matter during its incorporation into sediments. This study investigates the technique of supercritical fluid extraction (SFE) for the isolation of saturated, branched, unsaturated, and hydroxy-substituted fatty acids from a model siliceous matrix (silica-fused silica boiling stones) and two clays (montmorillonite and kaolinite). Spike-recovery experiments from the model matrix were performed to determine the effects of SFE temperature (40-100$\sp\circ$C), pressure (100-400 atm), and modifier content on free fatty acid extractabilities. Threshold pressures were determined for all of the analytes, and kinetics of extraction at different temperatures were studied. Results of the spike-recovery experiments demonstrated that solubility was not a limiting factor in the extraction of saturated, branched, and unsaturated fatty acids from siliceous samples. Hydroxy fatty acids, however, were poorly soluble in supercritical CO$\sb2$, and addition of polar modifiers was necessary for their isolation. Increasing the temperature of extraction provided dramatic improvements in the recoveries of free fatty acids, with the exception of unsaturated acids, from the model matrix by facilitating analyte diffusion and providing the thermal energy necessary to overcome adsorption energies associated with hydrogen bonding and van der Waals interactions. At 100$\sp\circ$ and 400 atm, recoveries of branched and saturated fatty acids from boiling stones using pure CO$\sb2$ ranged from 80-102% with excellent RSD's (2-6%). The results of SFE experiments from clays which had been fortified with the analytes by a slurry-coating procedure demonstrated the profound influence of the matrix on the conditions required for extractability using SF's. The strength of clay-analyte hydrogen bonding interactions, van der Waals interactions, and coordination to lattice ions precluded the isolation of free fatty acids from fortified clays using pure CO$\sb2$ even at high SFE temperatures. Substantial improvements in recoveries were observed upon the addition of polar modifiers, which compete for active sorptive sites, or upon acid pre-treatment of the fortified clay prior to SFE, which presumably facilitates desorption by disruption clay-fatty acids interactions, thereby freeing the analyte for extraction.

The foundations of Husserl and Merleau-Ponty and the phenomenological critique of science
Creators: name: Backhaus, Gary Mark
Publisher: name: American University
Year: 2023

description: This dissertation concerns the possibility of a viable foundational philosophy in the phenomenologies of Husserl and Merleau-Ponty. Since a phenomenological foundation is an irruption out of, and a reaction against, the inability of modern science and the philosophy which supplies its presuppositions, to provide an adequate foundation, a critical examination of science is a necessary moment in the formulation of the sense, and the justification for a phenomenological foundation. We characterize the rigorous science of phenomenology as the attempt to grasp an apriori science which is neither a construction nor an abstraction. In the return "to the things themselves," Husserl identifies and dispels the theoretical biases of modernity. Of equal importance, is the necessity of grounding the primacy of phenomena over the theoretical abstraction called science. We also examine Husserl's analysis and critique of the historical western telos and its aberrational form in the modern interpretation. We argue that a foundational quest is necessary from a meta-ethical point of view. In order to amplify and corroborate the Husserlian thesis, the historical thesis of Hugh Kearney concerning the metaphysical genesis of science and the structural thesis of Thomas Kuhn concerning the paradigmatic style of science are promoted. The presuppositions of Cartesianism are then elaborated and their subsequent influence, especially manifest in the problems of experimental psychology, is highlighted. A second criticism is developed concerning the problematics in the Husserlian foundation itself. Through our own investigations and the criticisms of Merleau-Ponty, we demonstrate that the essential weakness involves the unwarranted bifurcation of Form and Matter within the doctrine of intentionality. This erroneous separation of these moments assumes the dualistic subject/object dichotomy as manifest in the foundation. This ontological partitioning is overcome by Merleau-Ponty through uncovering the pre-conscious constitution of bodily intentionality. The lived-body is neither consciousness nor thing, but is the transcendental foundation prior to the consciousness versus thing conceptual abstraction. Finally, we demonstrate the importance of Merleau-Ponty's gestural theory of language in order to promote the most viable foundational philosophy of our time, the phenomenology of Merleau-Ponty.

description: It is known that approximating the Regge-Wheeler Potential with step functions significantly modifies the Schwarzschild black hole quasinormal mode spectrum. Surprisingly, this change in the spectrum has little impact on the ringdown waveform. We examine whether this issue is caused by the jump discontinuities and/or the piecewise constant nature of step functions. We show that replacing the step functions with a continuous piecewise linear function does not qualitatively change the results. However, in contrast to previously published results, we discover that the ringdown waveform can be approximated to arbitrary precision using either step functions or a piecewise linear function. Thus, this approximation process provides a new mathematical tool to calculate the ringdown waveform. In addition, similar to normal modes, the quasinormal modes of the approximate potentials seem to form a complete set that describes the entire time evolution of the ringdown waveform. We also examine smoother approximations to the Regge-Wheeler potential, where the quasinormal modes can be computed exactly, to better understand how different portions of the potential impact various regions of the quasinormal mode spectrum.

description: This paper introduces a sharp interface method to simulate fluid-structure interaction (FSI) involving rigid bodies immersed in viscous incompressible fluids. The capabilities of this methodology are demonstrated for a range of benchmark test cases along with large-scale models of biomedical FSI. The numerical approach developed herein, which we refer to as an immersed Lagrangian-Eulerian method, integrates aspects of partitioned and immersed FSI formulations by solving separate momentum equations for the fluid and solid subdomains, as in a partitioned formulation, while also using non-conforming discretizations of the dynamic fluid and structure regions, as in an immersed formulation. A Dirichlet-Neumann coupling scheme is used, in which the motion of the immersed solid is driven by fluid traction forces evaluated along the fluid-structure interface, and the motion of the fluid along that interface is constrained to match the solid velocity and thereby satisfy the no-slip condition. To develop a practical numerical method, we adopt a penalty approach that approximately imposes the no-slip condition along the fluid-structure interface. Our fluid-structure interaction scheme relies on an immersed interface method for discrete geometries, which enables the accurate determination of both velocities and stresses along complex fluid-structure interfaces. Unlike commonly used partitioned FSI methods, which can suffer from so-called added mass effect instabilities, our methodology retains stability for test cases involving extremely small, nearly equal, equal, and large solid-fluid density ratios without requiring subiterations or complex handling of the pressure. Biomedical FSI demonstration cases are also presented including the dynamics of a bileaflet mechanical heart valve in a pulse duplicator, and transport of blood clots in a patient-averaged anatomical model of the inferior vena cava.

description: The study attempts to assess the economic viability of afforestation of poor quality agricultural lands. The change in the direction of use of the poorest soils is justified both for environmental and agro-economic reasons. Assumptions regardingt he increase in the forest cover ratio have been inscribed in the National Woodland Extension Programme for over 20 years. The analyses showed that afforestation of the poorest agricultural lands executed with the support of the so-called “Afforestation programme” under the RDP may result in an improvement in agricultural income. Obtaining positive effects in this area, however, depends on, the possibility of carrying out afforestation and care works with the involvement of only own workforce.
Numerical investigation of quantum phases and phase transitions in a two-leg ladder of Rydberg atoms

description: Experiments on chains of Rydberg atoms appear as a new playground to study quantum phase transitions in 1D. As a natural extension, we report a quantitative ground-state phase diagram of Rydberg atoms arranged in a two-leg ladder that interact via van der Waals potential. We address this problem numerically, using the Density Matrix Renormalization Group (DMRG) algorithm. Our results suggest that, surprisingly enough, $\mathbb{Z}_k$ crystalline phases, with the exception of the checkerboard phase, appear in pairs characterized by the same pattern of occupied rungs but distinguishable by a spontaneously broken $\tilde{\mathbb{Z}}_2$ symmetry between the two legs of the ladder. Within each pair, the two phases are separated by a continuous transition in the Ising universality class, which eventually fuses with the $\mathbb{Z}_k$ transition, whose nature depends on $k$. According to our results, the transition into the $\mathbb{Z}_2\otimes \tilde{\mathbb{Z}}_2$ phase changes its nature multiple of times and, over extended intervals, falls first into the Ashkin-Teller, latter into the $\mathbb{Z}_4$-chiral universality class and finally in a two step-process mediated by a floating phase. The transition into the $\mathbb{Z}_3$ phase with resonant states on the rungs belongs to the three-state Potts universality class at the commensurate point, to the $\mathbb{Z}_3$-chiral Huse-Fisher universality class away from it, and eventually it is through an intermediate floating phase. The Ising transition between $\mathbb{Z}_3$ and $\mathbb{Z}_3\otimes \tilde{\mathbb{Z}}_2$ phases, coming across the floating phase, opens the possibility to realize lattice supersymmetry in Rydberg quantum simulators.

description: The paper presents economic effects of using GHG emission reduction technologies on model farms. Replacement of traditional tillage with aggregate for direct tillage and seeding (as contractor services) caused increase in annual operation cost of tillage on the model farm by 308.5%. Total annual operation costs of farm machinery on model farm (including costs of contractor services) increased by 25.2% in spite of a decrease in Diesel oil consumption by 26.8%. CO2 emissions per value unit of production decreased by 22.6%. Replacement of traditional crop production technology with energy-efficient one causes reduction of CO2 emission per value unit of obtained production by 22.6%. Change of technology, advisable from the ecological point of view, is not realistic because of the increase in the machinery operation costs and decrease in the production value on model farm. This barrier could be overcome with the use of relevant financial support, which however has adequate consequences for the state budget.

description: Agricultural market in Poland changed significantly after Poland’s accession to the European Union. New entities emerged in the value chain of agricultural production, profitability of all links of the chain grew and the model of servicing agricultural producers underwent a major change. Entities such as Gmina Cooperatives “Samopomoc Chłopska” or Spółdzielnie Kółek Rolniczych (Farmers’ Cooperative Associations) that were vital for distribution of means for agricultural production until 1989 – today are almost insignificant. Their role was taken over by private companies that very often started their activity on the grounds of property of bankrupt rural cooperatives. Changes on the market of means for agricultural production in Poland proceeded differently to those in other countries of the Central and Eastern Europe. The main reason for this was different structure of farms – the key customers of the market, their legal, economic and social status. In the Czech Republic, Slovakia or Bulgaria there was much fewer very small private agricultural entrepreneurs. Whereas the distribution channels in Western Europe were formed by several decades of free market economy. The model of distribution in Poland continues to evolve adjusting its offer to the dynamics of changes of their customers. Participants of agricultural market seek new possibilities to create and capture value, i.e. the highest margins in the chain of companies participating in manufacturing and supplying products to the final customer. The strongest ones try vertical and horizontal integration as well as different forms of partnership to shorten the distribution channels and take over as much value added as possible in the entire chain.
