description: We propose that the recently defined persistent homology dimensions are a practical tool for fractal dimension estimation of point samples. We implement an algorithm to estimate the persistent homology dimension, and compare its performance to classical methods to compute the correlation and box-counting dimensions in examples of self-similar fractals, chaotic attractors, and an empirical dataset. The performance of the $0$-dimensional persistent homology dimension is comparable to that of the correlation dimension, and better than box-counting.

description: The Bethe-Salpeter equation for Wick-Cutkosky like models is solved in dressed ladder approximation. The bare vertex truncation of the Dyson-Schwinger equations for propagators is combined with the dressed ladder Bethe-Salpeter equation for the scalar S-wave bound state amplitudes. With the help of spectral representation the results are obtained directly in Minkowski space. We give a new analytic formula for the resulting equation simplifying the numerical treatment. The bare ladder approximation of Bethe-Salpeter equation is compared with the one with dressed ladder. The elastic electromagnetic form factors is calculated within the relativistic impulse approximation.

description: Chandra HRC observations are investigated for evidence of proper motion and brightness changes in the X-ray jet of the nearby radio galaxy M87. Using images spanning 5 yr, proper motion is measured in the X-ray knot HST-1, with a superluminal apparent speed of $6.3 \pm 0.4 c$, or $24.1 \pm 1.6\rm\ mas\ yr^{-1}$, and in Knot D, with a speed of $2.4\pm 0.6c$. Upper limits are placed on the speeds of the remaining jet features. The X-ray knot speeds are in excellent agreement with existing measurements in the radio, optical, and ultraviolet. Comparing the X-ray results with images from the Hubble Space Telescope indicates that the X-ray and optical/UV emitting regions co-move. The X-ray knots also vary by up to 73% in brightness, whereas there is no evidence of brightness changes in the optical/UV. Using the synchrotron cooling models, we determine lower limits on magnetic field strengths of $\sim 420~μ\rm G$ and $\sim 230~μ\rm G$ for HST-1 and Knot A, respectively, consistent with estimates of the equipartition fields. Together, these results lend strong support to the synchrotron cooling model for Knot HST-1, which requires that its superluminal motion reflects the speed of the relativistic bulk flow in the jet.

description: Soil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on crop performance in PTE-contaminated soils have not yet been recognized globally. Here, a meta-analysis of 153 studies with 3213 individual observations was conducted to evaluate the effects of AMF on the growth and PTE accumulation of five staple crops (wheat, rice, maize, soybean, and sorghum) in contaminated soils. Our results demonstrated that AMF had strong positive effects on the shoot and root biomass. This is because AMF can effectively alleviate oxidative damage induced by PTEs by stimulating photosynthesis, promoting nutrition, and activating non-enzymatic and enzymatic defense systems in crop plants. AMF also decreased shoot PTE accumulation by 23.6% and increased root PTE accumulation by 0.8%, demonstrating that AMF effectively inhibited the PTE transfer and uptake by crop shoot. Meanwhile, AMF-mediated effects on shoot PTE accumulation were weaker in soils with pH > 7.5. Overall, this global survey has essential implications on the ability of AMF to enhance crop performance in PTE-contaminated soils and provides insights into the guidelines for safe agricultural production worldwide.

description: In this work, a correspondence between black hole solutions of conformal and massive theories of gravity is found. It is seen that this correspondence imposes some constraints on parameters of these theories. What is more, a relation between the mass of black holes and the parameters of massive gravity is found. Indeed, the acceptable ranges of massive gravity parameters ($c_{1}$\ and $c_{2}$) are found. It is shown that by considering the positive mass of black holes, some ranges of $c_{1}$\ and $c_{2}$ are acceptable.

Diseases of the Head: Essays on the Horrors of Speculative Philosophy
Creators: name: Rosen, Matt
Publisher: name: punctum books
Year: 2020

description: Diseases of the Head is an anthology of essays from contemporary philosophers, artists, and writers working at the crossroads of speculative philosophy and speculative horror. At once a compendium of multivocal endeavors, a breviary of supposedly illicit ponderings, and a travelogue of philosophical exploration, this collection centers itself on the place at which philosophy and horror meet. Employing rigorous analysis, incisive experimentation, and novel invention, this anthology asks about the use that speculation can make of horror and horror of speculation, about whether philosophy is fictional or fiction philosophical, and about the relationship between horror, the exigencies of our world and time, and the future developments that may await us in philosophy itself. From philosophers working on horrific themes, to horror writers influenced by heresies in the wake of post-Kantianism, to artists engaged in projects that address monstrosity and alienation, Diseases of the Head aims at nothing less than a speculative coup d'état. Refusing both total negation and absolute affirmation, refusing to deny everything or account for everything, refusing the posture of critique and the posture of all-encompassing unification, this collection of essays aims at exposition and construction, analysis and creation – it desires to fight for some thing, but not everything, and not nothing. And it desires, most of all, to speak from the position of its own insufficiency, its own partiality, its own under-determinacy, which is always indicative of the practice of thinking, of speculation. Considering themes of anonymity, otherness and alterity, the gothic, extinction and the world without us, the end times, the apocalypse, the ancient and the world before us, and the uncanny or unheimlich, among other motifs, this anthology seeks to articulate the cutting edge which can be found at the intersection of speculative philosophy and speculative horror.

The supply determinants of the developing countries' penetration of the US market for manufactures
Creators: name: Panoutsopoulos, Vasilis Dinysios
Publisher: name: The Australian National University
Year: 1990
Subjects: subject: Exports Developing countries
subject: Manufactures Developing countries

description: Although exports of labour intensive manufactures from developing countries have expanded rapidly since the 1950s, export pessimism persists in many forms. In recent years it has been argued that the markets of industrial economies, which take almost two thirds of the manufactured exports of developing (and centrally planned) economies, are being saturated so that further growth of these exports must be limited. The first part of this study is devoted to testing the 'saturation' hypothesis. This involved the further improvement of a concordance created in 1980-81 between trade and manufacturing production data so as to make them internationally comparable, and the creation of a data set of world manufacturing production and trade. The market penetration of manufactured exports from developing countries in industrial market economies was then calculated. It is clear that while there is considerable variance in market penetration by product and country, overall there is considerable room for a shift of supply of manufactures from capital intensive industrial market economies to countries with an ample supply of labour. In the second part of the study the data set was used to explain the patterns of penetration of the United States market for manufactures. In particular, the East Asian economies have been more successful than Latin American economies in penetrating the US markets. The market condi tions facing exporters have been broadly similar for all coun"tries. If anything, the newly indus trializing Eas t Asian economies have faced more barriers than other developing country exporters. In contrast to the export pessimists' approach which focuses on the demand country factors, the analysis concentrates on the supply country factors. The results indicate that several economic factors, including the size of the manufacturing sector, the rate of domestic inflation and exchange rate valuation, are important. Nevertheless, there is considerable la ti tude in domes tic policies that permi ts success in spite of deviations from an optimal policy framework. What seems to be important is a country's 'export culture'; that is, the degree of commitment to exporting and its embodiment in collective attitudes of poli ticians, bureaucrats and entrepreneurs towards finding ways to ensure that exporting is successful.

The Unnaming of Aliass
Creators: name: Bolender, Karin
Publisher: name: punctum books
Year: 2020

description: The Unnaming of Aliass performs a paradoxical quest for wildly “untold” stories in the company of one special donkey companion, a femammal of the species Equus asinus and, significantly, a registered “American Spotted Ass.” Beast of burden that she is, this inscrutable companion helped carry a ridiculous load of human longings and quandaries into a maze of hot, harrowing miles, across the US South from Mississippi to Virginia, in the summer of 2002 -- all the while carrying her own onerous and unreckoned burdens and histories. Over two decades, the original journey evolved -- from the cracking-open of a quasi-Western novel-that-never-was by an implosive pun, into an ongoing philosophical and assthetic adventure: a hybrid roadside- and barnyard-based living-art practice, wherein “Aliass” un/names something much harder to grasp than the body of a lovely little ass: protagonist, setting, and traditional Western narratives turn inside-out around this “name-that-ain’t.” Through a deeply dug-in questioning of its own authorial assumptions, The Unnaming of Aliass makes space for untold autobiographies and bright dusty lacunae, tracing ineffable tales through the tangled shapes and shadows that interweave in any environment.

description: The characteristic map for the symmetric group is an isomorphism relating the representation theory of the symmetric group to symmetric functions. An analogous isomorphism is constructed for the symmetric space of symplectic forms over a finite field, with the spherical functions being sent to Macdonald polynomials with parameters $(q,q^2)$. An analogue of parabolic induction is interpreted as a certain multiplication of symmetric functions. Applications are given to Schur-positivity of skew Macdonald polynomials with parameters $(q,q^2)$ as well as combinatorial formulas for spherical function values.
description: Major revision. v1 Theorem 4.7 is incorrect and replaced with v2 Theorem 4.9. The product defined in Section 4.4 is replaced with a module structure. The application to the structure constants for Macdonald polynomials is replaced with an application to the Schur expansion of skew Macdonald Polynomials. The dependence on character sheaves is removed and the connection explained in a new section

description: Mechanisms of pattern formation---of which the Turing instability is an archetype---constitute an important class of dynamical processes occurring in biological, ecological and chemical systems. Recently, it has been shown that the Turing instability can induce pattern formation in discrete media such as complex networks, opening up the intriguing possibility of exploring it as a generative mechanism in a plethora of socioeconomic contexts. Yet, much remains to be understood in terms of the precise connection between network topology and its role in inducing the patterns. Here, we present a general mathematical description of a two-species reaction-diffusion process occurring on different flavors of network topology. The dynamical equations are of the predator-prey class, that while traditionally used to model species population, has also been used to model competition between antagonistic ideas in social systems. We demonstrate that the Turing instability can be induced in any network topology, by tuning the diffusion of the competing species, or by altering network connectivity. The extent to which the emergent patterns reflect topological properties is determined by a complex interplay between the diffusion coefficients and the localization properties of the eigenvectors of the graph Laplacian. We find that networks with large degree fluctuations tend to have stable patterns over the space of initial perturbations, whereas patterns in more homogenous networks are purely stochastic.

description: MW031 is a biosimilar candidate of denosumab (Prolia®). This study aimed to compare the pharmacokinetics, pharmacodynamics, safety and immunogenicity of MW031 to denosumab in healthy Chinese participants. In this single-center, randomized, double-blind, parallel-controlled, single-dose trial, participants were given 60 mg MW031 (N = 58) or denosumab (N = 61) by subcutaneous injection and observed for 140 days. The primary endpoint was the bioequivalence of PK parameters (Cmax, AUC0-∞), and secondary endpoints including PD parameter, safety, and immunogenicity. A comparison of main PK parameters showed that the geometric mean ratios (GMR) (90% confidence intervals [CIs]) of AUC0-∞ and Cmax for MW031 over denosumab were 105.48% (98.96%, 112.43%) and 98.58% (92.78%, 104.75%), respectively. The inter-CV values of AUC0-∞ and Cmax for MW031 ranged from 19.9% to 23.1%. PD parameter (sCTX) in the MW031 and denosumab groups were similar, and the positivity rates of immunogenicity were 0% in both groups. This study also showed similar safety profiles in both groups, and there were no drug-related, high-incidence and previously unreported adverse reactions. This trial confirmed similar pharmacokinetic profiles of MW031 and denosumab in healthy male participants, and pharmacodynamic profile, immunogenicity and safety were comparable for both drugs.

description: In this presentation Harrison W. Inefuku, Scholarly Publishing Services Librarian at Iowa State University Library, discusses how Iowa State University Digital Press is working to increases the diversity of ideas, culturesand experiences represented in the scholarly record.

This presentation was delivered as part of the workshop: “Bridging Altruism To Strategy in OA Book Publishing: How Libraries Can Close Funding Gaps to Support a Bibliodiverse Global Shared Collection” (1 May 2024, online). The workshop was organised by Lyrasis in collaboration with Open Book Futures (a Copim Community research project, co-funded by Arcadia and the Research England Development fund).

The workshop explored how libraries can better respond to the strategic and practical challenges of supporting bibliodiverse futures for open access (OA) book publishing. The event focused in particular on the new and distinct strategies required to connect the dots between different aspects of library workflows, from ensuring quality of content, to collections development, to rendering content – and especially open access content – discoverable and available for users.

Trade and competition in Korean manufacturing
Creators: name: Min, Byung-Seong
Publisher: name: The Australian National University
Year: 1994

description: The primary objective of this thesis is to examine the efficiency and welfare effects on Korean manufacturing of an increase in competition from foreign firms. The Korean case is of interest because it represents an experience with liberalisation of a protected manufacturing sector in a small open economy. In the study, the imperfectly competitive nature of Korea's manufacturing sector is explicitly incorporated into the model. The analysis focuses first on the effects of an increase in foreign competition on domestic monopoly power, X-efficiency and national welfare. The market concentration of Korean manufacturing industry remained high throughout the 1970s and 1980s. The evidence suggests that financial subsidies to industry accelerated the level of market concentration, and that protection, especially through import quotas, was associated with high levels of X-inefficiency. The analysis also indicates that, in a small open economy, a rise in foreign competition has positive welfare effects, even when the economy is characterised by oligopoly and scale economies.

description: For more than three centuries, faith has offered the Lipovan Russians the support of ethnic identity. Demonstrating an amazing ability to survive in hostile environments, given the phenomenon of acculturation characteristic of the multiethnic spaces in which they lived, the Lipovan Russians have kept the original identity manifestations almost unchanged throughout history. An important factor in maintaining identity practices has been the isolation offered by Delta. An example of this is the village of Sarichioi, where the community is fully represented by Lipovan Russians who are proud of their cultural heritage. This specific and diversified heritage of the Dobrogea region has made it possible to link Romanian culture to European cultural heritage. Over time, some customs and traditions have been abandoned and others have been "adapted" to compensate for the lack of specific creations for certain community practices. In this study, we will refer to the integration of religious song into the Christmas carol, a traditional creation that has a specific purpose, that of marking an imminent event.

description: We review the recent results in the physics of the magnetic monopoles in gluodynamics and a dual formulation of non-Abelian theories, relevant to the physics of the confinement. It occurs that the dual gluon is a U(1) gauge boson, despite of the fact that usual gluons are non-Abelian. The effective infrared Lagrangian for gluodynamics is suggested which leads to the Casimir scaling of the string tension for quarks in various representations. We also show that the results of the calculations in lattice gauge theories confirm our theoretical predictions.

description: We propose a theoretical model of the light-induced director slippage effect. In this effect the bulk director reorientation contributes to the surface director reorientation It is found that the director and ellipticity profiles, obtained in the geometric optics approximation, are dependent on the ellipticity of the incident light wave. The director distribution is spatially modulated in linearly polarized light but grows monotonically in circularly polarized light. The surface director deviation has been examined, and comparison made with existing experimental data, which then permits the magnitude of the orientational nonlinearity coefficient to be calculated.

description: The deposition of solid phosphorus-based mineral particles is a common problem in urine diversion systems, which occurs in transport systems, particularly in horizontal pipelines. In this work, particle deposition behaviour in turbulent flow in a 3D horizontal pipe was simulated by using the Euler–Lagrange method. The effects of particle diameter, particle density, particle shape factor and fluid flow velocity on particle deposition behaviour were investigated. The results showed that the deposition rate increased by 9.92%,6.88% and 6.88% with increasing particle diameter (10-90 μm), particle density (1400 kg/m3–2300 kg/m3), and particle shape factor (0.2–1), respectively. For particles with larger diameters (>90 μm) or larger density (>2300 kg/m3), the deposition rate of these particles was almost reached 100%. It was found that gravitational sedimentation was the dominant deposition mechanism in low fluid flow velocity range (0.1–0.5 m/s). As fluid flow velocity increased (>0.5 m/s), turbulent fluctuation became the dominant factor that affected particle motion behaviour, whereas the effect of gravitational sedimentation on particle deposition behaviour declined significantly, and the increase in fluid flow velocity no longer significantly affects deposition rate. It was found that the deposition rate decreased by 29.13% as the fluid flow velocity was increased from 0.1 m/s to 0.5 m/s, while the corresponding deposition rate only decreased by 14.24% when the fluid flow velocity was increased from 0.5 m/s to 2 m/s. The optimal flow velocity was found to range between 0.75 and 1.25 m/s, which may mitigate the deposition of mineral solids in urine diversion systems.

description: Magnetic field geometry is expected to play a fundamental role in magnetar activity. The discovery of a phase-variable absorption feature in the X-ray spectrum of SGR 0418+5729, interpreted as cyclotron resonant scattering, suggests the presence of very strong non-dipolar components in the magnetic fields of magnetars. We performed a deep XMM-Newton observation of pulsar 1E 2259+586, to search for spectral features due to intense local magnetic fields. In the phase-averaged X-ray spectrum, we found evidence for a broad absorption feature at very low energy (0.7 keV). If the feature is intrinsic to the source, it might be due to resonant scattering/absorption by protons close to star surface. The line energy implies a magnetic field of ~ 10^14 G, roughly similar to the spin-down measure, ~ 6x10^13 G. Examination of the X-ray phase-energy diagram shows evidence for a further absorption feature, the energy of which strongly depends on the rotational phase (E >~ 1 keV ). Unlike similar features detected in other magnetar sources, notably SGR 0418+5729, it is too shallow and limited to a small phase interval to be modeled with a narrow phase-variable cyclotron absorption line. A detailed phase-resolved spectral analysis reveals significant phase-dependent variability in the continuum, especially above 2 keV. We conclude that all the variability with phase in 1E 2259+586 can be attributed to changes in the continuum properties which appear consistent with the predictions of the Resonant Compton Scattering model.

description: We consider the production of gravitational KK modes via cosmological photon-photon and electron-positron annihilation in models with large factorisable extra dimensions. We place constraints on this production using recent results from a joint analysis of the power spectra of the 2dF Galaxy Redshift Survey (2dFGS) and the cosmic microwave background (CMB) anisotropies. We obtain a more accurate upper limit for the temperature corresponding to matter-radiation equality and show that, even for the case of 6 extra dimensions and a fundamental scale of 1 TeV, a period of inflation is required that ends at a temperature much lower than that of the QCD phase transition.

Relativistic Instant--Form Approach to the Structure of Two-Body Composite Systems. II. Nonzero Spin

description: The relativistic approach to electroweak properties of two-particle composite systems developed in previous work is generalized here to the case of nonzero spin. This approach is based on the use of the instant form of relativistic Hamiltonian dynamics. The generalization makes use of a special mathematical technique for the parametrization of matrix elements of electroweak current operators in terms of form factors. In this technique the parametrization is a realization of theWigner--Eckart theorem on the Poincaré group and form factors are reduced matrix elements. As in the case of zero spin the electroweak current matrix element satisfies the relativistic covariance conditions and in the case of electromagnetic current it also automatically satisfies the conservation law. Physical approximations such as, for example, the relativistic impulse approximation, are formulated in terms of reduced matrix elements. The electromagnetic structure of $ρ$ meson is calculated as an example of realization of the technique proposed.

description: In this thesis, computational quantum chemistry has been used to investigate the factors influencing the reactivity of nitroxides and other stable free radicals, and their relevance to the important biochemical processes and useful practical applications. At all stages, accuracy and appropriateness of the chosen theoretical procedures was validated via benchmarking against higher levels of theory and/or experimentally measured values. Results of the theoretical modelling were analysed in the context of available literature data and, where relevant, in the context of numerical kinetic models, and the following key discoveries were made. A new type of electrostatic effect on radical stability, that is potentially general and non-directional and arises in the enhanced polarisability of highly delocalised electrons, has been discovered and investigated. This through-space stabilising interaction between remote negative charges and delocalised radicals is associated with an unusual non-aufbau orbital configuration with a potential in molecular electronics, and impacts significantly upon the energetics of chemical reactions, in which the extent of electron delocalisation changes. This finding has a huge range of practical applications, and is shown to have significant implications for enzyme catalysis and biological autooxidation. Furthermore, the basic scheme of autooxidative degradation of organic molecules under elevated temperatures and/or UV light was revised so as to reflect the low reactivity of peroxyl radicals towards the hydrogen abstraction and explain the surprising antioxidant effect of oxygen. On this basis, a number of stabilisation strategies were suggested, according to the chemical structure of the degrading substrate. One such strategy is the use of hindered amine light stabilisers (HALSs), and the true mechanisms behind their remarkable efficiency have been clarified in this thesis for the first time. The corresponding new nitroxide chemistry was also found relevant to the side-reactions disrupting nitroxide mediated polymerization (NMP), and the strategies for their minimisation have been proposed. Combined with the discovered pH switching, this knowledge was utilised in the design of switchable control agents for room-temperature NMP. Finally, the reversible redox chemistry of nitroxides was employed to design novel redox mediators for dye-sensitised solar cells (DSSCs), one of which has been subsequently shown to double the cell’s energy conversion efficiency.

description: We present an approach to enhance wheeled planetary rover dead-reckoning localization performance by leveraging the use of zero-type constraint equations in the navigation filter. Without external aiding, inertial navigation solutions inherently exhibit cubic error growth. Furthermore, for planetary rovers that are traversing diverse types of terrain, wheel odometry is often unreliable for use in localization, due to wheel slippage. For current Mars rovers, computer vision-based approaches are generally used whenever there is a high possibility of positioning error; however, these strategies require additional computational power, energy resources, and significantly slow down the rover traverse speed. To this end, we propose a navigation approach that compensates for the high likelihood of odometry errors by providing a reliable navigation solution that leverages non-holonomic vehicle constraints as well as state-aware pseudo-measurements (e.g., zero velocity and zero angular rate) updates during periodic stops. By using this, computationally expensive visual-based corrections could be performed less often. Experimental tests that compare against GPS-based localization are used to demonstrate the accuracy of the proposed approach. The source code, post-processing scripts, and example datasets associated with the paper are published in a public repository.

description: The gluon propagator is investigated in Landau and in maximal center gauge for the gauge group SU(2) by means of lattice gauge simulations. We find that Gribov ambiguities arising from the implementation of Landau gauge have a small influence on the propagator. In agreement with previous findings, we obtain that the small momentum behavior is dominated by a mass, which is of order $(1.48 \pm 0.05) \sqrtσ$, where $σ$ is the string tension. By removing the confining vortices from the full Yang-Mills ensemble, we convert full YM-theory into a theory which does not confine quarks. We find that in the latter case the strength of the gluon propagator in the intermediate momentum range is strongly reduced. The spectral functions which reproduce the numerical data for the propagators are analyzed using a generalized Maximum Entropy Method.

description: An important factor in tumor development and progression is the tumor microenvironment (TME), which is heterogeneous. Previous studies have mainly investigated the expression profile and prognostic values of genes in gastric cancer (GC) at the cell population level but neglected the interactions and heterogeneity between cells. The pattern of ligand–receptor (LR) interactions was delineated on a scRNA-seq dataset containing 44,953 cells from nine GC patients and a fourth bulk RNA-seq dataset including data from 1159 GC patients. We then constructed an LR.Score scoring model to comprehensively evaluate the influence of LR-pairs on the TME, overall survival, and immunotherapy response in GC patients from several cohorts. Cell communication network among 13 cell types was constructed based on the LR-pairs. We proposed a new molecular subtyping model for GC based on the LR-pairs and revealed the differences in prognosis, pathophysiologic features, mutation characteristics, function enrichment, and immunological characteristics among the three subtypes. Finally, an LR.Score model based on LR-pairs was developed and validated on several datasets. Based on the selected LR-pairs, we successfully constructed a novel prediction model and observed its well performance on molecular subtyping, target and pathway screening, prognosis judging, and immunotherapy response predicting.
Macroscopic spin tunneling and quantum critical behavior of a condensate in double-well potential

description: In a previous work (PRL 87, 140405), we have shown that a spinor condensate confined in a periodic or double-well potential exhibits ferromagnetic behavior due to the magnetic dipole-dipole interactions between different wells, and in the absence of external magnetic field, the ground state has a two-fold degeneracy. In this work, we demonstrate the possibility of observing macroscopic quantum spin tunneling between these two degenerate states and show how the tunneling rate critically depends on the strength of the transverse field.
