description: We prove that the determinacy of Gale-Stewart games whose winning sets are accepted by real-time 1-counter Büchi automata is equivalent to the determinacy of (effective) analytic Gale-Stewart games which is known to be a large cardinal assumption. We show also that the determinacy of Wadge games between two players in charge of omega-languages accepted by 1-counter Büchi automata is equivalent to the (effective) analytic Wadge determinacy. Using some results of set theory we prove that one can effectively construct a 1-counter Büchi automaton A and a Büchi automaton B such that: (1) There exists a model of ZFC in which Player 2 has a winning strategy in the Wadge game W(L(A), L(B)); (2) There exists a model of ZFC in which the Wadge game W(L(A), L(B)) is not determined. Moreover these are the only two possibilities, i.e. there are no models of ZFC in which Player 1 has a winning strategy in the Wadge game W(L(A), L(B)).

Kohn-Sham band gaps and potentials of solids from the optimised effective potential method within the random phase approximation

description: We present an implementation of the optimised effective potential (OEP) scheme for the exact-exchange (EXX) and random phase approximation (RPA) energy functionals and apply these methods to a range of bulk materials. We calculate the Kohn-Sham (KS) potentials and the corresponding band gaps and compare them to the potentials obtained by standard local density approximation (LDA) calculations. The KS gaps increase upon going from the LDA to the OEP in the RPA and finally to the OEP for EXX. This can be explained by the different depth of the potentials in the bonding and interstitial regions. To obtain the true quasi-particle gaps the derivative discontinuities or $G_0W_0$ corrections need to be added to the RPA-OEP KS gaps. The predicted $G_0W_0$@RPA-OEP quasi-particle gaps are about 5% too large compared to the experimental values. However, compared to $G_0W_0$ calculations based on local or semi-local functionals, where the errors vary between different materials, we obtain a rather consistent description among all the materials.

description: This study provides a comprehensive test of the head-related impulse response (HRIR) to an auditory spatial speller brain-computer interface (BCI) paradigm, including a comparison with a conventional virtual headphone-based spatial auditory modality. Five BCI-naive users participated in an experiment based on five Japanese vowels. The auditory evoked potentials obtained produced encouragingly good and stable P300-responses in online BCI experiments. Our case study indicates that the auditory HRIR spatial sound paradigm reproduced with headphones could be a viable alternative to established multi-loudspeaker surround sound BCI-speller applications.

description: We present a novel direct integral pseudospectral (PS) method (a direct IPS method) for solving a class of continuous-time infinite-horizon optimal control problems (IHOCs). The method transforms the IHOCs into finite-horizon optimal control problems (FHOCs) in their integral forms by means of certain parametric mappings, which are then approximated by finite-dimensional nonlinear programming problems (NLPs) through rational collocations based on Gegenbauer polynomials and Gegenbauer-Gauss-Radau (GGR) points. The paper also analyzes the interplay between the parametric maps, barycentric rational collocations based on Gegenbauer polynomials and GGR points, and the convergence properties of the collocated solutions for IHOCs. Some novel formulas for the construction of the rational interpolation weights and the GGR-based integration and differentiation matrices in barycentric-trigonometric forms are derived. A rigorous study on the error and convergence of the proposed method is presented. A stability analysis based on the Lebesgue constant for GGR-based rational interpolation is investigated. Two easy-to-implement pseudocodes of computational algorithms for computing the barycentric-trigonometric rational weights are described. Two illustrative test examples are presented to support the theoretical results. We show that the proposed collocation method leveraged with a fast and accurate NLP solver converges exponentially to near-optimal approximations for a coarse collocation mesh grid size. The paper also shows that typical direct spectral/PS- and IPS-methods based on classical Jacobi polynomials and certain parametric maps usually diverge as the number of collocation points grow large, if the computations are carried out using floating-point arithmetic and the discretizations use a single mesh grid whether they are of Gauss/Gauss-Radau (GR) type or equally-spaced.

description: The scattering of three-dimensional inertia-gravity waves by a turbulent geostrophic flow leads to the redistribution of their action through what is approximately a diffusion process in wavevector space. The corresponding diffusivity tensor was obtained by Kafiabad, Savva & Vanneste (2019, J. Fluid Mech., 869, R7) under the assumption of a time-independent geostrophic flow. We relax this assumption to examine how the weak diffusion of wave action across constant-frequency cones that results from the slow time dependence of the geostrophic flow affects the distribution of wave energy. We find that the stationary wave-energy spectrum that arises from a single-frequency wave forcing is localised within a thin boundary layer around the constant-frequency cone, with a thickness controlled by the acceleration spectrum of the geostrophic flow. We obtain an explicit analytic formula for the wave-energy spectrum which shows good agreement with the results of a high-resolution simulation of the Boussinesq equations.

description: The goal of Text-to-Speech (TTS) synthesis in a particular language is to convert arbitrary input text to intelligible and natural sounding speech. However, for a particular language like Hindi, which is a highly confusing language (due to very close spellings), it is not an easy task to identify errors/mistakes in input text and an incorrect text degrade the quality of output speech hence this paper is a contribution to the development of high quality speech synthesis with the involvement of Spellchecker which generates spell suggestions for misspelled words automatically. Involvement of spellchecker would increase the efficiency of speech synthesis by providing spell suggestions for incorrect input text. Furthermore, we have provided the comparative study for evaluating the resultant effect on to phonetic text by adding spellchecker on to input text.

description: General concepts and strategies are developed for identifying the isomorphism type of the second p-class group \(G=Gal(F_p^2(K) | K)\), that is the Galois group of the second Hilbert p-class field \(F_p^2(K)\), of a number field K, for a prime p. The isomorphism type determines the position of G on one of the coclass graphs G(p,r), \(r\ge 0\), in the sense of Eick, Leedham-Green, and Newman. It is shown that, for special types of the base field K and of its p-class group \(Cl_p(K)\), the position of G is restricted to certain admissible branches of coclass trees by selection rules. Deeper insight, in particular, the density of population of individual vertices on coclass graphs, is gained by computing the actual distribution of second p-class groups G for various series of number fields K having p-class groups \(Cl_p(K)\) of fixed type and p in {2,3,5,7}.

description: Non-melanoma skin cancers are defined those epithelial malignancies such as basal and squamous cell carcinomas as well as some rare cutaneous malignancies. There are various surgical and non-surgical treatment modalities. The main goal of such treatments is complete tumour eradication with optimal cosmesis and functional outcome. Surgery is considered the most effective treatment, especially for high-risk tumours. Incomplete surgical excision of non-melanoma skin cancers (NMSC) most commonly basal and squamous cell carcinomas, the commonest skin cancers are relatively frequent occurrences. If neglected can invade locally and cause significant destruction. These tumours can be classified as high or low risk according to localisation mostly in the head region or their metastatic risk. Dermoscopy is a non-invasive and effective diagnostic technique that aids preoperative assessment of surgical margins.

description: Electronic structure and thermoelectric properties of marcasite (m) and synthetic pyrite (p) phases of FeX$_2$ (X=Se,Te) have been investigated using first principles density functional theory and Boltzmann transport equation. The plane wave pseudopotential approximation was used to study the structural properties and full-potential linear augmented plane wave method was used to obtain the electronic structure and thermoelectric properties (thermopower and power factor scaled by relaxation time). From total energy calculations we find that m-FeSe$_2$ and m-FeTe$_2$ are stable at ambient conditions and no structural transition from marcasite to pyrite is seen under the application of hydrostatic pressure. The calculated ground state structural properties agree quite well with available experiments. From the calculated thermoelectric properties, we find that both m and p forms are good candidates for thermoelectric applications. However, hole doped m-FeSe$_2$ appears to be the best among all the four systems.

description: We investigate the regular or chaotic nature of orbits of stars moving in the meridional plane $(R,z)$ of an axially symmetric galactic model with a flat disk and a central, non spherical and massive nucleus. In particular, we study the influence of the flattening parameter of the central nucleus on the nature of orbits, by computing in each case the percentage of chaotic orbits, as well as the percentages of orbits of the main regular families. In an attempt to maximize the accuracy of our results upon distinguishing between regular and chaotic motion, we use both the Fast Lyapunov Indicator (FLI) and the Smaller ALingment Index (SALI) methods to extensive samples of orbits obtained by integrating numerically the equations of motion as well as the variational equations. Moreover, a technique which is based mainly on the field of spectral dynamics that utilizes the Fourier transform of the time series of each coordinate is used for identifying the various families of regular orbits and also to recognize the secondary resonances that bifurcate from them. Varying the value of the flattening parameter, we study three different cases: (i) the case where we have a prolate nucleus (ii) the case where the central nucleus is spherical and (iii) the case where an oblate massive nucleus is present. Furthermore, we present some additional findings regarding the reliability of short time (fast) chaos indicators, as well as a new method to define the threshold between chaos and regularity for both FLI and SALI, by using them simultaneously. Comparison with early related work is also made.

description: We present an updated analysis of the intrinsic colors of SNe Ia using the latest data release of the Carnegie Supernova Project. We introduce a new light-curve parameter very similar to stretch that is better suited for fast-declining events, and find that these peculiar types can be seen as extensions to the population of "normal" SNe Ia. With a larger number of objects, an updated fit to the Lira relation is presented along with evidence for a dependence on the late-time slope of the B-V color-curves with stretch and color. Using the full wavelength range from u to H band, we place constraints on the reddening law for the sample as a whole and also for individual events/hosts based solely on the observed colors. The photometric data continue to favor low values of Rv, though with large variations from event to event, indicating an intrinsic distribution. We confirm the findings of other groups that there appears to be a correlation between the derived reddening law, Rv, and the color excess, E(B-V), such that larger E(B-V) tends to favor lower Rv. The intrinsic u-band colors show a relatively large scatter that cannot be explained by variations in Rv or by the Goobar (2008) power-law for circumstellar dust, but rather is correlated with spectroscopic features of the supernova and is therefore likely due to metallicity effects.

description: Vehicles on the road exchange data with base station (BS) frequently through vehicle to infrastructure (V2I) communications to ensure the normal use of vehicular applications, where the IEEE 802.11 distributed coordination function (DCF) is employed to allocate a minimum contention window (MCW) for channel access. Each vehicle may change its MCW to achieve more access opportunities at the expense of others, which results in unfair communication performance. Moreover, the key access parameters MCW is the privacy information and each vehicle are not willing to share it with other vehicles. In this uncertain setting, age of information (AoI) is an important communication metric to measure the freshness of data, we design an intelligent vehicular node to learn the dynamic environment and predict the optimal MCW which can make it achieve age fairness. In order to allocate the optimal MCW for the vehicular node, we employ a learning algorithm to make a desirable decision by learning from replay history data. In particular, the algorithm is proposed by extending the traditional DQN training and testing method. Finally, by comparing with other methods, it is proved that the proposed DQN method can significantly improve the age fairness of the intelligent node.

Year: 2017

description: Robit small-scale irrigation scheme is located in the Amhara National Regional State and

was constructed in 2012. However, the performance of the irrigation scheme has not been

evaluated yet. In the present study, the performance of the scheme was evaluated by

estimating water delivery performance indicators, water conveyance efficiency, water

conveyance losses, and satisfaction of irrigation users. The water delivery performance

adequacy, efficiency, equity and dependability were evaluated by monitoring discharge at

nine selected offtakes; three each at the head, middle and tail end of the scheme command

area during the crop season from April to June 2017. The water conveyance efficiency of

the main and secondary canals and thus the water losses in water conveyance were

estimated by measuring irrigation water flow at different locations along the canals. The

satisfaction of the irrigation water users from the irrigation service received was

evaluated using the binary Logit Model at the head, middle and tail end of the irrigation

scheme, and for the entire irrigation scheme. Irrigation water flow in the main and

secondary canals, as well as at nine tertiary offtakes was measured using Current meter

and 3-inch Parshall flume. The data were analyzed using STATA, CROPWAT, ARC GIS

software, and Microsoft Excel. The water delivery performance indicators adequacy,

efficiency, equity and dependability varied widely from head to tail reach and, during the

crop season from April to June with overall average value equal to 0.88, 0.92, 0.09 and

0.11 respectively. Thus, the irrigation scheme when compared with Molden and Gates

(1990) standards was found under fair condition in adequacy and dependability and

under good condition in efficiency and equity.

We find that higher order lasers can drive donut shaped blowout wakefields with strong positron accelerating gradients comparable to those of a spherical bubble. Corresponding positron focusing forces can be more than an order of magnitude stronger than electron focusing forces in a spherical bubble. Required laser intensities and energies to reach the non-linear donut shaped blowout are within state-of-the-art experimental conditions.

description: In this paper, upper limits on the total luminosity of ultra-high-energy cosmic rays (UHECR) (E > $10^{18}$ eV) are determined for five individual sources. The upper limit on the integral flux of GeV-TeV gamma-rays of a given source is used to extract the upper limit on the total UHECR luminosity. The correlation between upper limit on the integral GeVTeV gamma-ray flux and upper limit on the UHECR luminosity is established through the cascading process that takes place during propagation of the cosmic rays in the background radiation fields, as explained in reference [1]. Twenty-eight sources measured by FERMI-LAT, VERITAS and MAGIC observatories have been studied. The measured upper limit on the GeV-TeV gamma-ray flux is restrictive enough to allow the calculation of an upper limit on the total UHECR cosmic-ray luminosity of five sources. The upper limit on the UHECR cosmicray luminosity of these sources is shown for several assumptions on the emission mechanism. For all studied sources an upper limit on the ultra-high-energy proton luminosity is also set.

description: Molecular spintronics devices (MSDs) are highly promising candidates for enabling quantum computation and revolutionizing computer logic and memory. An advanced MSD will require the placement of magnetic molecules between the two ferromagnetic (FM) electrodes. Recent experimental studies showed that some magnetic molecules produced unprecedented strong exchange couplings between the two FM electrodes leading to intriguing magnetic and transport properties in a MSD. Future development of MSDs will critically depend on obtaining an in-depth understanding of the molecule induced exchange coupling, and its impact on switchability, functional temperature range, and stability. However, the large size of MSD systems and fragile device fabrication scheme continue to limit the theoretical and experimental studies of magnetic attributes produced by molecules in a MSD. This paper theoretically studies the MSD by performing Monte Carlo simulations (MCS). Our MCS encompasses the full range of MSDs that can be realized by establishing different kinds of magnetic interaction between magnetic molecules and FM electrodes. Our MSDs are represented by a 2D Ising model. We studied the effect of a wide range of molecule-FM electrode couplings on the basic properties of MSDs. This wide range covered (i) molecule possessing ferromagnetic coupling with both FM electrodes, (ii) molecule possessing antiferromagnetic coupling with both FM electrodes, and (iii) molecule possessing ferromagnetic coupling with one electrode and antiferromagnetic coupling with another FM electrode. Our MCS will enable the fundamental understanding and designing of a wide range of novel MSDs utilizing a variety of molecules and FM electrodes; these studies will also benefits nanomaterials based spintronics devices employing nanoclusters and quantum dots as the device elements.
Oral vocabulary and learning to read morphologically complex words: mechanisms of influence

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: It is well-established that there is a causal relationship between oral vocabulary and written word reading. However, it is not clear in what ways oral vocabulary facilitates reading and how morphological information interacts with this facilitation. This thesis aims to examine a cognitive mechanism recently proposed to explain the facilitatory role of oral vocabulary on reading and the potential role of morphology on the use of this cognitive mechanism. Chapter I consists of a literature review in order to present an overview of the relevant evidence for oral vocabulary being causally associated with reading. Possible cognitive mechanisms are discussed. One such mechanism, the orthographic skeleton hypothesis, which is tested in the present study, is described in detail. The chapter further overviews the evidence on how readers use their morphological knowledge while reading and how orthographic skeletons could be linked with reading morphologically complex words. The type of morphological complexity (inflection and derivation) as well as their relevance to skeletons and reading in general are discussed. Chapter II is an empirical investigation of the skeleton hypothesis for two types of morphologically complex novel words (inflected and derived) using a novel oral word learning paradigm, followed by one of two written tasks: self-paced reading or lexical recognition. The first aim was to test whether orthographic skeletons were formed for the stems (i.e., bases) of morphologically complex words upon oral training of these complex words, whereas the second aim was to investigate whether orthographic skeletons were formed independently of affix type. The main findings relate to lexical recognition and indicated that orthographic skeletons are built for the stems of complex words, and this is not dependent on the type of affix. Interactions between phonology, orthography and morphology during the process of reading new words are discussed.

Enhancing Plasmodium research through plasmorutils: A one-stop R package for apicomplexan biology
Creators: name: Rohit Satyam

Publisher: name: F1000 Research Limited
Year: 2024

description: The major bottleneck in understanding Plasmodium biology is the relative lack of omics-driven experimental data and the presence of attention biases. Compounding this issue, half of the Plasmodium proteome encodes proteins whose functions remain unknown, aggravating the challenges. This is also true for other apicomplexan parasites. Although the PlasmoDB database offers the latest annotations for all Plasmodium species, it does not integrate or reference information from numerous privately maintained databases. Besides, some of these databases provide annotation using discontinued gene/protein IDs. Accessing these databases typically requires manual effort, which is both cumbersome and time-consuming for both wet-lab personnel and bioinformaticians. The PlasmoRUtils R package tackles these obstacles by providing various single-liner R functions for web scraping using gene IDs as input and summarising the results as data tables. It interfaces with databases like HitPredict, ApicoTFDB, Malaria.tools, MPMP database, MIIP, Phenoplasm, PlasmoBase, MalBoost, Uniprot, and others. Additionally, it offers a variety of utility functions and vignettes for visualizing UniProt annotations, conducting GO/pathway enrichment analysis using the MPMP dataset, and performing other routine bioinformatic analyses typically difficult and non-trivial for non-model organisms. This package also provides functions that simplify the creation of ready-to-use Seurat objects for multiple single-cell datasets from the Malaria Cell Atlas (MCA) and other similar Apicomplexan datasets. The annotations gathered from these databases and in-house analyses will be made available through an easily accessible and queryable Shiny web server, designed to be user-friendly for those outside the bioinformatics community. plasmoRUtils is accompanied by the plasmoRdata package, which holds essential datasets (single-cell datasets and reanalyzed bulk RNAseq datasets uniformly analyzed by our nextflow pipeline RNAgrinder) routinely used by researchers for tasks such as single-cell annotation, hypothesis testing, and exploring gene expression patterns throughout the life cycle. It also includes gene annotations generated by our lab, annotations from published literature, and protein-protein interaction data. The development of PlasmoRUtils and PlasmoRdata fills a vital gap in the data resources available for apicomplexan parasites research in the R environment. These packages are designed to ease data retrieval, facilitate integration from different sources, and improve the reproducibility of scientific research in combating one of the world's most severe infectious diseases.

description: The one-dimensional Rice-Mele lattice consisting of two-site unit cells enables topological charge pumping at low enough temperatures. We show here that energy pumping is feasible in this system. We analyze energy polarization using the second-quantization formalism and connect it to intercell energy current by the relevant continuity equation. Following this formulation, we numerically evaluate the energy current pumped in an adiabatic cycle when the system parameters vary periodically and slowly with time. Unlike the pumped charge, the pumped energy is entirely temperature-independent at half filling. The global Berry phase for all bands and the related topological phase transitions during the pumping cycle account for the energy pumping. The present study paves the way for manipulating energy current without electric and thermal biases.

description: This paper is devoted to the presentation of the lateral Casimir force between two sinusoidally corrugated eccentric cylinders. Despite that applying scattering matrix method explains the problem exactly, procedure of applying this method is somehow complicated specially at nonzero temperature. Using the proximity force approximation (PFA) helps to achieve the lateral Casimir force in a truly explicit manner. We assume the cylinders to be slightly eccentric with similar radiuses and separations much smaller than corrugations' wave length for the validity of PFA. For such short distances the effect of finite conductivity would be non negligible. In addition to the effect of finite conductivity, we investigate thermal corrections of the lateral Casimir force to reduce the inaccuracy of the result obtained by PFA. Assuming the Casimir force density between two parallel plates, the normal Casimir force between two cylinders is obtained. With the aid of additive summation of the Casimir energy between cylinders without corrugation, we obtain the lateral Casimir force between corrugated cylinders.

description: In this article we consider resummed expressions for the heat-kernel's trace of a Laplace operator, the latter including a potential and imposing Dirichlet semitransparent boundary conditions on a surface of codimension one in flat space. We obtain resummed expressions that correspond to the first and second order expansion of the heat-kernel in powers of the potential. We show how to apply these results to obtain the bulk and surface form factors of a scalar quantum field theory in $d=4$ with a Yukawa coupling to a background. A characterization of the form factors in terms of pseudo-differential operators is given. Additionally, we discuss a connection between heat-kernels for Dirichlet semitransparent, Dirichlet and Robin boundary conditions.

description: In this research, the attempt is made to highlight the alternatives to development by studying the Urban Commons. Its main purpose is the understanding of the Urban Commons and the effect of discourse on their formation, having as its subject the former Karatassiou camp. To achieve this, an overview of the relevant literature is first carried out and then, applied examples of Urban Commons are examined, in order to ascertain the characteristics that make them up. Having ascertained the characteristics of the Urban Commons and bearing in mind the power of discourse, articles concerning the former Karatassiou camp are examined to determine if they project the Public, Private or Common character of this space. Finally, gathering the results of this research, an attempt is made to highlight the effect of discourse on the final formation of the character of the former Karatassiou camp.

description: Textile and garment industries in Ethiopia are opt as priority sector for the economic as well as industrial development of the country. In realizing this objective, the performances, challenges and prospects of these industries require the attention of its stakeholders. Identifying the export challenges and measuring the export performance level with different performance measures help to resolve the problems of the industry. The prospects of the industries also need due consideration to attract foreign investment to the sector. The overall objective of this research is to assess the export performances, challenges and prospects of Textile and Garment industries in Ethiopia. The research design used for the study was a descriptive research design. The qualitative approach was followed to assess the challenges and prospects of the industry while the quantitative approach used to assess the export performances of the industry. Questioner and interview were used as the primary data collection tools. The major findings of this study indicated that the export performance of the sector during 2012/13 GC to 2016/17 GC was improved by 138.9% from the preceding five years period. The exporting firms’ growth also scored a positive growth (on average 16.5%). However, the result obtained by annual export sales growth (on average negative 1.3%) and export sales to plan ratio (on average 34.5%) indicated that the performances obtained did not reach to the required level. The paradox observed here is the average annual export sales growth with the average exporting firms’ growth. The average export sale to GDP (Gross Domestic Product) ratio (0.26%) shows that the contribution of the export sales of this sector to GDP was insignificant. The main products exported from this sector are garment, fabrics, yarn and cultural cloths.

Networks of Influence Diagrams: A Formalism for Representing Agents' Beliefs and Decision-Making Processes

description: This paper presents Networks of Influence Diagrams (NID), a compact, natural and highly expressive language for reasoning about agents beliefs and decision-making processes. NIDs are graphical structures in which agents mental models are represented as nodes in a network; a mental model for an agent may itself use descriptions of the mental models of other agents. NIDs are demonstrated by examples, showing how they can be used to describe conflicting and cyclic belief structures, and certain forms of bounded rationality. In an opponent modeling domain, NIDs were able to outperform other computational agents whose strategies were not known in advance. NIDs are equivalent in representation to Bayesian games but they are more compact and structured than this formalism. In particular, the equilibrium definition for NIDs makes an explicit distinction between agents optimal strategies, and how they actually behave in reality.
