description: The simulation of two-dimensional (2D) wave propagation is an affordable computational task and its use can potentially improve time performance in vocal tracts' acoustic analysis. Several models have been designed that rely on 2D wave solvers and include 2D representations of three-dimensional (3D) vocal tract-like geometries. However, until now, only the acoustics of straight 3D tubes with circular cross-sections have been successfully replicated with this approach. Furthermore, the simulation of the resulting 2D shapes requires extremely high spatio-temporal resolutions, dramatically reducing the speed boost deriving from the usage of a 2D wave solver. In this paper, we introduce an in-progress novel vocal tract model that extends the 2D Finite-Difference Time-Domain wave solver (2.5D FDTD) by adding tube depth, derived from the area functions, to the acoustic solver. The model combines the speed of a light 2D numerical scheme with the ability to natively simulate 3D tubes that are symmetric in one dimension, hence relaxing previous resolution requirements. An implementation of the 2.5D FDTD is presented, along with evaluation of its performance in the case of static vowel modeling. The paper discusses the current features and limits of the approach, and the potential impact on computational acoustics applications.

description: We analyzed responsiveness of KRAS-mutated CRC cell lines with distinctive MSI status against mitogen-activated protein kinase (MEK) inhibitor (selumetinib; AZD) and/or B-raf proto-oncogene (BRAF) kinase inhibitor (vemurafenib; PLX). The viability of MSI-high (MSI-H) KRAS-mutated LS174T cells treated with AZD or PLX was 24.5 ± 0.9% or 71.4 ± 3.6%, respectively, and the viability of microsatellite stable (MSS) KRAS-mutated SW480 cells for AZD or PLX was 57.4 ± 3.1% or 43.1 ± 1.8%, respectively. These observations imply that the therapeutic efficacy of MEK kinase inhibitors or BRAF kinase inhibitors against KRAS-mutated colon cancer cells may differ between MSI-H and MSS. However, a combination of both inhibitors synergistically inhibits the proliferation of KRAS-mutated colon cancer cells regardless of MSI status. The underlying synergistic cytotoxic efficacy of AZD/PLX combination on KRAS-mutated colon cancer cells with different MSI status was further substantiated by markedly decreased phosphorylation of ERK in both LS74T and SW480 cell lines upon AZD and PLX treatment. Based on these collective data, we propose that MSI status should be considered when MEK kinase inhibitor or BRAF kinase inhibitor is treated for KRAS-mutated colon cancer, and that combination of both inhibitors synergistically inhibit proliferation of KRAS-mutated colon cancer cells independent of MSI status.

description: We study a mobile quantum impurity, possessing internal rotational degrees of freedom, confined to a ring in the presence of a many-particle bosonic bath. By considering the recently introduced rotating polaron problem, we define the Hamiltonian and examine the energy spectrum. The weak-coupling regime is studied by means of a variational ansatz in the truncated Fock space. The corresponding spectrum indicates that there emerges a coupling between the internal and orbital angular momenta of the impurity as a consequence of the phonon exchange. We interpret the coupling as a phonon-mediated spin-orbit coupling and quantify it by using a correlation function between the internal and orbital angular momentum operators. The strong-coupling regime is investigated within the Pekar approach and it is shown that the correlation function of the ground state shows a kink at a critical coupling, that is explained by a sharp transition from the non-interacting state to the states that exhibit strong interaction with the surroundings. The results might find applications in such fields as spintronics or topological insulators, where spin-orbit coupling is of crucial importance.

description: Mixing (or quasirandom) properties of the natural transition matrix associated to a graph can be quantified by its distance to the complete graph. Different mixing properties correspond to different norms to measure this distance. For dense graphs, two such properties known as spectral expansion and uniformity were shown to be equivalent in seminal 1989 work of Chung, Graham and Wilson. Recently, Conlon and Zhao extended this equivalence to the case of sparse vertex transitive graphs using the famous Grothendieck inequality. Here we generalize these results to the non-commutative, or `quantum', case, where a transition matrix becomes a quantum channel. In particular, we show that for irreducibly covariant quantum channels, expansion is equivalent to a natural analog of uniformity for graphs, generalizing the result of Conlon and Zhao. Moreover, we show that in these results, the non-commutative and commutative (resp.) Grothendieck inequalities yield the best-possible constants.

description: We present measurements of galactic outflow rates from the EAGLE suite of cosmological simulations. We find that gas is removed from the interstellar medium (ISM) of central galaxies with a dimensionless mass loading factor that scales approximately with circular velocity as $V_{\mathrm{c}}^{-3/2}$ in the low-mass regime where stellar feedback dominates. Feedback from active galactic nuclei (AGN) causes an upturn in the mass loading for halo masses $> 10^{12} \, \mathrm{M_\odot}$. We find that more gas outflows through the halo virial radius than is removed from the ISM of galaxies, particularly at low redshift, implying substantial mass loading within the circum-galactic medium (CGM). Outflow velocities span a wide range at a given halo mass/redshift, and on average increase positively with redshift and halo mass up to $M_{200} \sim 10^{12} \, \mathrm{M_\odot}$. Outflows exhibit a bimodal flow pattern on circum-galactic scales, aligned with the galactic minor axis. We present a number of like-for-like comparisons to outflow rates from other recent cosmological hydrodynamical simulations, and show that comparing the propagation of galactic winds as a function of radius reveals substantial discrepancies between different models. Relative to some other simulations, EAGLE favours a scenario for stellar feedback where agreement with the galaxy stellar mass function is achieved by removing smaller amounts of gas from the ISM, but with galactic winds that then propagate and entrain ambient gas out to larger radii.

description: The unusual supernova SN1998bw, which is thought to be related to the gamma-ray burster GRB980425, is a possible link between the two classes of objects. Analyzing the extensive radio emission data avaliable for SN1998bw, we are able to describe its time evolution within the well established framework available for the analysis of radio emission from supernovae. This then allows description of a number of physical properties of the object. The radio emission can best be explained as interaction of a mildly relativistic (Gamma about 1.6) shock with a dense pre-explosion stellar wind established circumstellar medium (CSM) which is highly structured both azimuthally, in clumps or filaments, and radially, with two observed density enhancements separated by about 3e17 cm. With assumptions as to pre-explosion stellar wind conditions, it is possible to estimate that the progenitor to SN 1998bw had a mass loss rate of about 3.5e-5 solar masses per yr with at least two approximately 30% increases in mass-loss rate; the most recent extending from about 1,600 - 4,700 yr before explosion and the oldest known having occurred, with possibly comparable length, about 12,000 yr before explosion. Because of its unusual characteristics for a Type Ib/c SN, the relation of SN1998bw to GRB980425 is strengthened with consequent improvement in our understanding of these poorly understood objects.

description: We numerically integrated the orbits of 1458 particles in the region of the classical Kuiper Belt (41 AU < a < 47 AU) to explore the role of dynamical instabilities in sculpting the inclination distribution of the classical Kuiper Belt Objects (KBOs). We find that the selective removal of low-inclination objects by overlapping secular resonances (nu_17 and nu_18) acts to raise the mean inclination of the surviving population of particles over 4 billion years of interactions with Jupiter, Saturn, Uranus and Neptune, though these long-term dynamical effects do not themselves appear to explain the discovery of KBOs with inclinations near 30 degrees. Our integrations also imply that after 3 billion years of interaction with the massive planets, high inclination KBOs more efficiently supply Neptune-encountering objects, the likely progenitors of short-period comets, Centaurs, and scattered KBOs. The secular resonances at low inclinations may indirectly cause this effect by weeding out objects unprotected by mean motion resonances during the first 3 billion years.

description: An exact integro-differential equation for the conformal map from the unit circle to the boundary of an evolving cavity in a stressed 2-dimensional solid is derived. This equation provides an accurate description of the dynamics of precursors to fracture when surface diffusion is important. The solution predicts the creation of sharp grooves that eventually lead to material failure via rapid fracture. Solutions of the new equation are demonstrated for the dynamics of an elliptical cavity and the stability of a circular cavity under biaxial stress, including the effects of surface stress.

description: The investigations on organic semiconductors and organometal halide perovskite (OHP) semiconductors have enabled tremendous research achievements for low cost, high performance, flexible optoelectronic applications such as light emitting diodes (LED), photovoltaics (PV) and field effect transistors (FET). In this thesis, we discuss two individual projects. The first project is device architecture design for achieving fast organic memory. The second project is targeting on achieving general observation of clean field effect operation in OHP transistor which is currently the major problem in the community. In the first project, we developed a new memory device based on vertical transistor configuration which scales down the effective gate modulation length below 2 micrometer (m) and incorporates a two charge transport layer structure where the bottom is an ambipolar semiconductor layer for fast charge accumulation and the top is a unipolar semiconductor layer for maintaining device transfer curve in unipolar characteristic. By this configuration, memory function can be achieved as reliable writing between ON/OFF states with ratio ~ 100, in fast speed with programming ~ 150 ns and erasing ~ 50 ns. These speed values are nearly seven orders of magnitude higher than those reported in lateral organic transistor memory based on unipolar semiconductor. In the second project, we investigated solution processed defect-removal technique for pursing high performance OHP transistors. We proposed a three-step solution treatment as cleaning-healing-cleaning to reduce defects in OHP surface and gain boundaries. We investigated ion migrations (magnitude, mobility, activation energy) on OHP samples as-deposited and post-treated by cleaning or healing using different solutions. We optimized the three-step treatment based on ion migration results and applied the optimal treatment on transistor manufacturing, achieving clean field effect modulations with mobility improved two to three orders of magnitude compared with transistors of pristine OHP films. We explored the optimal treatment on OHP films with grain size up to 1 m, achieving unprecedented high transistor mobility averaging at 3.0 cm2/Vs at 300 K and 9.2 cm2/Vs at 80 K. Additionally, we show this method is in line with high quality transformation from PbI2 single crystals into thin OHP micro-plates.

description: The problem of automatic and accurate forecasting of time-series data has always been an interesting challenge for the machine learning and forecasting community. A majority of the real-world time-series problems have non-stationary characteristics that make the understanding of trend and seasonality difficult. Our interest in this paper is to study the applicability of the popular deep neural networks (DNN) as function approximators for non-stationary TSF. We evaluate the following DNN models: Multi-layer Perceptron (MLP), Convolutional Neural Network (CNN), and RNN with Long-Short Term Memory (LSTM-RNN) and RNN with Gated-Recurrent Unit (GRU-RNN). These DNN methods have been evaluated over 10 popular Indian financial stocks data. Further, the performance evaluation of these DNNs has been carried out in multiple independent runs for two settings of forecasting: (1) single-step forecasting, and (2) multi-step forecasting. These DNN methods show convincing performance for single-step forecasting (one-day ahead forecast). For the multi-step forecasting (multiple days ahead forecast), we have evaluated the methods for different forecast periods. The performance of these methods demonstrates that long forecast periods have an adverse effect on performance.

description: This study aimed to explore qualitatively the psychological experience of recovery from relative energy deficiency in sport (RED-S). More specifically, it sought to understand: how RED-S is experienced from a psychological perspective; sources of psychological conflict in the ongoing management of energy availability (EA); and athlete responses to psychological conflict in the pursuit of optimal EA.MethodsEight female endurance athletes identifying as “in recovery” or “recovered” from RED-S (M age = 29.78 years) participated in this integrated methods multiple case-study. Participants engaged in an initial topical life history interview, before completing an online diary over a 21-day period, taking photographs of psychological triggers for seven days, and participating in a follow-up interview. Data were analysed using reflexive thematic analysis.ResultsThe theme in too deep and treading water captured the significant psychological implications of RED-S. Seven sources of psychological conflict reported while managing EA were identified. The theme a constant tug of war represented the responses to these sources of psychological conflict in the ongoing management of EA. Within this theme, the subthemes in two minds and an emotional rollercoaster illustrated the cognitive and affective responses to psychological conflict, while giving in and the only way is through represented the adaptive and maladaptive behavioural responses during recovery, respectively.ConclusionThis study offers novel insights into the complex nature of recovery from RED-S and highlights the importance of considering psychological factors underpinning improved physiological functioning and overall wellbeing during RED-S recovery.

description: The article aims to analyze the concept of eco-innovations emphasizing the motivations for implementing them, and effects of the eco-innovation process. The author presents the principal definitions of eco-innovations. Various motivations triggering eco-innovations are presented with a focus on regulatory and market factors. Entrepreneurs should be encouraged to adopt eco-innovations because they contribute to sustainable development which is the only way for a world that is challenged by global population growth, climate change, declining non-renewable resource stock, water shortages, and environmental degradation. The effects of eco-innovations can be both positive and negative. The main aim of eco-innovations is to decrease the environmental burdens of entrepreneurial activity. However, a new attitude towards eco-innovations emphasizes the role of economic returns and supplies security. The types of effects of environmentally friendly innovations discussed in the paper include environmental, technological, economic, social, cultural and managerial.

description: This thesis applies Animal Studies theory to a selection of texts from medieval literature and visual culture. In particular, it is concerned with the ways that the ‘fact of interaction’ impacts on an evaluation of non–human animal (NHA) and human–animal relationships. The thesis re–examines a selection of medieval texts by foregrounding the experience of the non–human animal in the human sphere, looking at how the two interact and seeking to emphasise the importance of NHAs. As the thesis progresses, I move from the material (manuscript skin; the flesh of animals in hunting and butchery) to the metaphorical (the use of animal sculpture and religious imagery). Although much of the thesis focusses on the ways in which animals are used in positive or affirming ways, I close with a consideration of the ways creatures were used to spread prejudice. I use a wide variety of sources (pragmatic manuscripts, images, sculpture, religious texts, lay texts, poetry) to demonstrate how far–reaching this concept is, and open up new avenues for scholarship. The concept of ‘use’ is also key here, as it includes both the pragmatic utilisation of animal bodies, but also the use of animals, as Lévi–Strauss had it, ’to think with’. In sum, I emphasise the importance of non–human animal experience in medieval human experience, and use relatively new critical apparatus from the field of Animal Studies to deepen our understanding of medieval texts.

description: Gallium nitride (GaN) is a key semiconductor for solid-state lighting, but its radiative processes are not fully understood. Here we show a first-principles approach to accurately compute the radiative lifetimes in bulk uniaxial crystals, focusing on wurtzite GaN. Our computed radiative lifetimes are in very good agreement with experiment up to 100 K. We show that taking into account excitons (through the Bethe-Salpeter equation) and spin-orbit coupling to include the exciton fine structure is essential for computing accurate radiative lifetimes. A model for exciton dissociation into free carriers allows us to compute the radiative lifetimes up to room temperature. Our work enables precise radiative lifetime calculations in III-nitrides and other anisotropic solid-state emitters.

description: This dissertation examines the circulation of Christian print and the making of Protestant thought in Brazil in the nineteenth and twentieth centuries. It investigates one of the central methods of Protestant evangelisation deployed in the country: the production and diffusion of evangelical literature. On the one hand, this work analyses the ideological and doctrinal contents of the literature circulated by evangelical agents in Brazil, showing how foreign missionaries and Portuguese-speaking ministers actively engaged with debates circulating in the country’s public sphere. On the other hand, it pays close attention to the trajectories of evangelical literature and takes into account the materiality of the books, tracts, and Bibles set in motion by evangelists and ministers. The expansion and consolidation of evangelical churches and societies in Brazil gave rise to new forms of religious sociability with their distinctive practices and identities, distinguished from the Catholic Church, the state, and the aristocratic institutions of the secular public sphere. By means of a complex and far-reaching network comprising churches, evangelical libraries, and colporteurs, Protestants circulated Christian literature widely in the country. Missionary societies and their transnational circuits connected the missionary work in Brazil with Portugal, Britain, and the United States, generating a Lusophone evangelical transatlantic public sphere. This dissertation pays close attention to the intellectual dimension of this movement, examining how Brazilian Protestant ministers modified concepts and ideas taken from a wide variety of intellectual and theological traditions to craft their own body of thought and doctrine. In this sense, this dissertation locates the evangelical work in Brazil, its ideas and practices, on both national and transnational scales, examining how evangelical agents mediated between different cultures, navigated through various intellectual landscapes, and domesticated evangelical Christianity.

description: Strong, fast pulses, called ``bang-bang'' controls can be used to eliminate the effects of system-environment interactions. This method for preventing errors in quantum information processors is treated here in a geometric setting which leads to an intuitive perspective. Using this geometric description, we clarify the notion of group symmetrization as an averaging technique, and provide a geometric picture for evaluating errors due to imperfect bang-bang controls. This will provide additional support for the usefulness of such controls as a means for providing more reliable quantum information processing.

description: The goal of the research was to present the role of investing in the agribusiness value chain as a factor impacting the change in the share of agriculture in GDP and, secondly, to show the dependencies between the share of the agricultural sector in GDP and the level of GDP per capita. In the article the authors drew attention to a potentially conflicting issue connected with the development of agriculture. On the one hand, investment in agribusiness and the rural sector contributes to the development of rural areas; on the other hand, countries with a large share of the agricultural sector in GDP have a much lower GDP per capita than countries with a low share of the agricultural sector in GDP. Therefore, it seems significant not to make investments only but to place them properly in the appropriate links of the agribusiness value chain. It could be better not to invest directly in agricultural areas, but in other agribusiness stages, decreasing the share of the agricultural sector in GDP. Increasing the share of the services and manufacturing sectors, which are directly or indirectly related to the agricultural sector can contribute to the decline in the share of agriculture in GDP. These changes can be made by re-training of persons connected with agriculture and searching for jobs for them in large urban areas or by enabling such persons to create jobs in the agriculture-related sector or by establishing non-agricultural companies in rural areas.

description: We introduce a simple and robust scheme for optical frequency transfer of an ultra-stable source light field via an optical frequency comb to a field at a target optical frequency, where highest stability is required, e.g. for the interrogation of an optical clock. The scheme relies on a topology for end-to-end suppression of the influence of optical path-length fluctuations, which is attained by actively phase-stabilized delivery, combined with common-path propagation. This approach provides a robust stability improvement without the need for additional isolation against environmental disturbances such as temperature, pressure or humidity changes. We measure residual frequency transfer instabilities by comparing the frequency transfers carried out with two independent combs simultaneously. Residual fractional frequency instabilities between two systems of $8\times10^{-18}$ at 1 s and $3\times10^{-21}$ at $10^5$ s averaging time are observed. We discuss the individual noise contributions to the residual instability. The presented scheme is technically simple, robust against environmental parameter fluctuations, and enables an ultra-stable frequency transfer, e.g. to optical clock lasers or to lasers in gravitational wave detectors.

description: Fifty-one objects in the 5_{-1}-4_0E methanol line at 84.5 GHz were detected during a survey of Class I maser sources. Narrow maser features were found in 17 of these. Broad quasi-thermal lines were detected towards other sources. One of the objects with narrow features, the young bipolar outflow L 1157 was also observed in the 8_0-7_1A+ line at 95.2 GHz; a narrow line was detected at this frequency. Analysis showed that the broad lines are usually inverted. The quasi-thermal profiles imply that the line opacities are not larger than several units. These results confirm the plausibility of models in which compact Class I masers appear in extended sources as a result of an appropriate velocity field. Measurements of linear polarization at 84.5 GHz in 13 sources were made. No polarization was found except a tentative detection of a weak polarization in M 8E.

On Problems in the Representation Theory of Symmetric Groups

linear characters of Sylow subgroups

description: In this thesis, we study the representation theory of the symmetric groups $\mathfrak{S}_n$, their Sylow $p$-subgroups $P_n$ and related algebras. For all primes $p$ and natural numbers $n$, we determine the maximum number of distinct irreducible constituents of degree coprime to $p$ of restrictions of irreducible characters of $\mathfrak{S}_n$ to $\mathfrak{S}_{n-1}$, and show that every value between 1 and this maximum is attained. These results can be stated graph-theoretically in terms of the Young lattice, which describes branching for symmetric groups. We present new graph isomorphisms between certain subgraphs of the Young lattice and find self-similar structures. This generalises from $p=2$ to all $p$ work of Ayyer, Prasad and Spallone which was central in the construction of character correspondences for symmetric groups in the context of the McKay Conjecture, a fundamental open problem in the representation theory of finite groups. Linear characters of Sylow subgroups have also played a central role in character correspondences verifying the McKay Conjecture, becoming the focus of much current interest. For instance, a consequence of recent work of Giannelli and Navarro shows the existence of linear constituents in the restriction of every irreducible character of a symmetric group to its Sylow $p$-subgroups. We now identify these linear constituents, using a mixture of algebraic and combinatorial techniques including Mackey theory and an analysis of Littlewood--Richardson coefficients. We determine precisely when the trivial character of $P_n$ appears as a constituent of the restriction of an irreducible character of $\mathfrak{S}_n$, for all $n$ and odd $p$. As a consequence, we determine the irreducible characters of the Hecke algebra corresponding to the induced permutation character. Analogous results are obtained for the alternating groups $\mathfrak{A}_n$. We then extend our scope to arbitrary linear characters of $P_n$, proving in particular that for all $p$, given linear characters $\phi$ and $\phi'$ of $P_n$, their inductions to $\mathfrak{S}_n$ are equal if and only if $\phi$ and $\phi'$ are $N_{\mathfrak{S}_n}(P_n)$--conjugate. Finally, we consider the representation theory of Schur algebras in all characteristics. We classify the classical Schur algebras $S(n,r)$ which are Ringel self-dual, using decomposition numbers for symmetric groups, tilting module multiplicities and combinatorial methods.

description: The paper studies the economic performance of sheep enterprises, the data pertain to 11 farms of the Lublin Province in 2012. There are 3 farms presented: one with the best farm income, one with the worst and the other with a “standard” medium farm income. The aim of this study was to compare the productivity (per 1 ha AL), where AL denotes arable land, and (per PLN 1) of direct costs on farms. The area of the farm did not affect the generated incomes. The standard farm had 19.07 ha AL and the best farm only 15.66 ha AL. A detailed analysis of the data allowed us to confirm the belief that direct payments did not affect economic results. The greatest support in the form of direct payments was in the “standard” farm.

description: The general objective of this study is to present the economic situation of Hungarian broiler production. A deterministic model was constructed to investigate the role of technical efficiency on profitability. As the results demonstrate, in current economic conditions broiler production can be profitable if the European Production Efficiency Factor (EPEF) is above 300-310. A lower level of technology, cheaper feed and chicks in addition to their weaker quality deteriorates the technical efficiency of production, which results in poor economic indicators. Therefore, it is not worth saving on either the level of technology or the quality of chicks or feed. Thus, the key purpose of future developments should be: increasing efficiency.
A note on the Drinfeld associator for genus-zero superstring amplitudes in twisted de Rham theory

description: The string corrections of tree-level open-string amplitudes can be described by Selberg integrals satisfying a Knizhnik-Zamolodchikov (KZ) equation. This allows for a recursion of the $α'$-expansion of tree-level string corrections in the number of external states using the Drinfeld associator. While the feasibility of this recursion is well-known, we provide a mathematical description in terms of twisted de Rham theory and intersection numbers of twisted forms. In particular, this leads to purely combinatorial expressions for the matrix representation of the Lie algebra generators appearing in the KZ equation in terms of directed graphs. This, in turn, admits efficient algorithms for symbolic and numerical computations using adjacency matrices of directed graphs and is a crucial step towards analogous recursions and algorithms at higher genera.

Nonlinear Turbulent Magnetic Diffusion and Mean-Field Dynamo

description: The nonlinear coefficients defining the mean electromotive force (i.e., the nonlinear turbulent magnetic diffusion, the nonlinear effective velocity, the nonlinear kappa-tensor, etc.) are calculated for an anisotropic turbulence. A particular case of an anisotropic background turbulence (i.e., the turbulence with zero mean magnetic field) with one preferential direction is considered. It is shown that the toroidal and poloidal magnetic fields have different nonlinear turbulent magnetic diffusion coefficients. It is demonstrated that even for a homogeneous turbulence there is a nonlinear effective velocity which exhibits diamagnetic or paramagnetic properties depending on anisotropy of turbulence and level of magnetic fluctuations in the background turbulence. Analysis shows that an anisotropy of turbulence strongly affects the nonlinear mean electromotive force. Two types of nonlinearities (algebraic and dynamic) are also discussed. The algebraic nonlinearity implies a nonlinear dependence of the mean electromotive force on the mean magnetic field. The dynamic nonlinearity is determined by a differential equation for the magnetic part of the alpha-effect. It is shown that for the alpha-Omega axisymmetric dynamo the algebraic nonlinearity alone cannot saturate the dynamo generated mean magnetic field while the combined effect of the algebraic and dynamic nonlinearities limits the mean magnetic field growth. Astrophysical applications of the obtained results are discussed.
