Species Diversity in Myxomycetes Based on the Morphological Species Concept - a Critical Examination

Using two databases, a world inventory of validly described taxa and a keyworded bibliography of myxomycete literature, research activities for myxomycetes from the year 1753 up to the present time have been documented by the authors. The numbers of described taxa and publications have both increased sharply during the last 30 years, reaching a total of 1012 described taxa of subgeneric rank, with about 1200 published papers presenting regional species lists and about 400 papers describing new taxa. An increasing number of recently described taxa appears to be very rare and is often known only from the type locality. With the well-known morphological plasticity of myxomycete fructifications caused by fluctuations in environmental conditions during development, it cannot be ruled out that aberrant fructifications have been described as new taxa under the current morphological species concept. On the other hand, many apomictic biotypes distinguished by only slight morphological differences may remain unrecognised. In this paper we propose a set of criteria to make descriptions of new taxa more comprehensive. Examples drawn from the authors' experiences illustrate the application of these criteria.
Adoption of E-Wallet Usefulness and E-Wallet Risk in Impulsive Buying: Testing the Moderating Role of Low Distribution Charges in Post Covid-19 Era

This study's goal is to evaluate the extent to which low distribution charges are contributing part in impulsive buying when the customers in Pakistan have prospect of digital money for environment sustainability.

Parameters Identification of a Permanent Magnet DC Motor: A Review

Since permanent magnet direct current (DC) motors are mainly used in various industrial automation applications, the demand for electric motors is increasing rapidly. However, in the mass production of electric motors, often, only random inspections are used to check the specifications and performance of electric motors. For manufacturing or engineering application staff to have a more thorough understanding of the characteristics of the motor, it is necessary to conduct a full or quick inspection during the production process to ensure the quality of the electric motor. Based on this, this literature review reveals several methods and algorithms often used to estimate DC motor parameters, given the importance of knowing the parameters of the DC motor and the lack of research on estimating the parameters of the DC motor.
Exploring self-regulated writing strategies: A comparison between paragraphs and essays

Writing requires a complex skill, and thus students need to regulate themselves in employing the appropriate strategies to achieve good writing performance. The present research investigated Self-Regulated Writing (SRW) strategies used by EFL (English as a Foreign Language) university students. It contrasted the students' strategies related to the complex structure of the texts (i.e., paragraphs and essays) and students’ writing performance. The data information came from two separate sets of self-regulated learning strategy questionnaire, as well as writing outcomes of the students. Descriptive statistics and the Mann-Whitney U test were utilized to evaluate the data. The six dimensions of SRW strategies were extensively utilized in paragraph and essay writings. The six dimensions include motive, method, time, performance, physical environment, and social environment. Interestingly, the social environment dimension had the highest mean score, showing that the students needed assistance from their peers and available learning resources. Meanwhile, the motive dimension obtained the lowest mean in both paragraph and essay writings. Furthermore, the analysis showed no significant statistical difference in using SRW strategies in writing paragraphs and essays except in the method dimension. The difference in strategy use based on achievement was also not significant. The results indicate that the students applied similar SRW strategies in paragraph and essay writings regardless of their proficiency levels. Pedagogical implications and recommendations for future research are also further discussed in the article.
Spectral theory of $\mathbb{Z}^{d}$ substitutions

In this paper, we generalize and develop results of Queffélec allowing us to characterize the spectrum of an aperiodic $\mathbb{Z}^{d}$ substitution. Specifically, we describe the Fourier coefficients of mutually singular measures of pure type giving rise to the maximal spectral type of the translation operator on $L^{2}$ , without any assumptions on primitivity or height, and show singularity for aperiodic bijective commutative $\mathbb{Z}^{d}$ substitutions. Moreover, we provide a simple algorithm to determine the spectrum of aperiodic $\mathbf{q}$ -substitutions, and use this to show singularity of Queffélec’s non-commutative bijective substitution, as well as the Table tiling, answering an open question of Solomyak. Finally, we show that every ergodic matrix of measures on a compact metric space can be diagonalized, which we use in the proof of the main result.
Occurrence and Contamination Level of Ochratoxin A in Tissues of Slaughtered Pigs in Greece

(Western Macedonia, Thessaly, Central Greece, Central Macedonia). The ochratoxin A presence in blood serum, kidney, liver, muscle, and fatty tissues in samples of slaughtered pigs was examined by using an enzyme-linked immunosorbent assay method. None of all kidney, liver, muscle, and fat samples were found ochratoxin A contaminated. A total of 579 (45.95%) of the 1260 analyzed serum samples were ochratoxin A contaminated in a range from 0.21 to 5.39 μ g/mL (mean level 0.66 μ g/mL) and ochratoxin A was present in serum in 65 (77.38%) of the 84 examined farms. The mean levels of ochratoxin A serum contamination in regions of Western Macedonia, Central Greece, and Central Macedonia were similar (0.29-0.32 μ g/mL). The highest ochratoxin A value (mean 1.20 μ g/L, median 0.53 μ g/L) with the highest coefficient of variation (1.12) was found in the Thessaly region. Although ochratoxin A was not found in pork meat in Greece, the presence of ochratoxin A in pig serum requires continuous och-ratoxin A monitoring in the swine industry and pork meat.
Ultrasonographic determination of anatomical measurements of tendinous structures and palmar metacarpals ligaments in Colombian Creole donkeys

Objective. To provide reference values for anatomical measurements of tendinous structures and metacarpal ligaments in Colombian Creole donkeys using ultrasonography as a measurement tool. Materials and methods . Ultrasonographic examination of the tendons and ligaments of the palmar metacarpal region of limbs was performed in 15 clinically healthy donkeys. The variables to be measured were: cross-sectional area (cm2), lateral medial width (ALM) (cm) and dorsal palmar thickness (EDP) (cm). Results. It was found that there is no difference in the measurements between the two members or in relation to sex. In addition, it was found that the structure with the largest area in the proximal areas (1A and 1B) was the suspensory ligament (0.548 cm2), and in the distal ones (2A and 2B) the deep digital flexor tendon (0.468 cm2). Conclusions. Anatomical measurements of the tendinous structures and the palmar metacarpal ligaments in Colombian Creole donkeys are similar to those found in the international literature. Reference values for anatomical (morphometric) measurements of palmar metacarpal tendons and ligaments in Colombian Creole donkeys were presented.
Extensions of J. Bourgain's double recurrence theorem

Ryo Moore: Extensions of J. Bourgain’s Double Recurrence Theorem (Under the direction of Idris Assani) The study of multiple recurrence averages was pioneered by Furstenberg in 1977, when he provided an alternative proof to Szemerédi’s theorem using ergodic theory, which states that a set of integer with a positive density contains an arbitrary long arithmetic progression. Since then, many convergence results of multiple recurrence averages have been obtained. Their norm convergence have been studied by Conze and Lesigne (in 1984), Host and Kra (2005), Ziegler (2006), Tao (2008), and the best result was obtained by Walsh (2012). The results are much scarcer for pointwise convergence. In 1990, Bourgain answered Furstenberg’s question by showing that some double recurrence averages converge pointwise. This deep result has not been generalized since then, while some partial results on the pointwise convergence of multiple recurrence averages are obtained by Derrien and Lesigne (1996), Assani (1998, 2005), and recently announced by Huang, Shao, and Ye (2014), and Donoso and Sun (2015). Also, Assani and Buczolich have shown that the pointwise convergence of double recurrence averages need not to hold when both functions are in L1. On the other hand, Brunel initiated the study of return times averages in his PhD thesis from 1966, where one concerns ergodic averages with weights that are generated randomly. In 2000, Assani showed that the sequence appearing in the multiple recurrence averages can be a good universal weight for multiple return times averages under some assumptions on the system. We will show that one can extend Bourgain’s double recurrence result in numerous ways. We will first show the Wiener-Wintner extension of the double recurrence theorem, which was a study initiated by Duncan in his doctoral dissertation from 2001. Furthermore, we will show a polynomial Wiener-Wintner result for the double recurrence theorem, extending the work of Lesigne (1990, 1993) and Frantzikinakis (2006). Secondly, from the angle of the Wiener-Wintner extension, we will show that the sequence appearing in the double recurrence averages can be a good universal weight for iii some nonconventional ergodic averages in norm, ultimately extending the work of Host and Kra, and Ziegler.
Non-monotone periodic orbits of a rotational horseshoe

In this paper, we present results for the forcing relation on the set of braid types of periodic orbits of a rotational horseshoe on the annulus. Precisely, we are concerned with a family of periodic orbits, called the Boyland family, and we prove that for each pair $(r,s)$ of rational numbers with $r<s$ in $(0,1)$ , there exists a non-monotone orbit $B_{r,s}$ in this family which has pseudo-Anosov type and rotation interval $[r,s]$ . Furthermore, the forcing relation among these orbits is given by the inclusion order on their rotation sets. It is also proved that the Markov partition associated to each Boyland orbit comes from a pruning map which projects to a bimodal circle map. This family also contains the Holmes orbits $H_{p/q}$ , which are the largest for the forcing order among all the $(p,q)$ -orbits of the rotational horseshoe.
A third order boundary value problem with nonlinear growth at resonance on the half‐axis

This paper is concerned with the solvability of a fully nonlinear third‐order m‐point boundary value problem at resonance posed on the half line. The nonlinearity which depends on the first and the second derivatives satisfies a sublinear‐like growth condition. Our main existence result is based on Mawhin's coincidence degree theory. An illustrative example of application is included. Copyright © 2016 John Wiley & Sons, Ltd.
Damage detection based on system identification of concrete dams using an extended finite element–wavelet transform coupled procedure

The aim of the present study is to propose a procedure for seismic cracking identification of concrete dams using a coupling of the extended finite element method (XFEM) based on cohesive crack segments (XFEM-COH) and continuous wavelet transform (CWT). First, the dam is numerically modeled using the traditional finite element method (FEM). Then, cracking capability is added to the dam structure by applying the XFEM-COH for concrete material. The results of both the methods under the seismic excitation have been compared and identified to damage detection purposes. In spite of predefined damage in some of the structural health monitoring (SHM) techniques, there is an advantage in the XFEM model where the whole dam structure is potentially under damage risk without initial crack, and may not crack at all. Finally, in order to evaluate any change in the system, that is, specification of any probable crack effects and nonlinear behavior, the structural modal parameters and their variation have been investigated using system identification based on the CWT. The results show that the extended finite element–wavelet transform procedure has high ability for the online SHM of concrete dams that by analysis of its results, the history of physical changes, cracking initiation time, and exact damage localization have been performed from comparing the intact (FEM) and damaged (XFEM) modal parameters of the structural response. In addition, any small change in the system is observable while the final crack profile and performance simulation of the dam body under strong seismic excitations have obtained.
Numerical Investigation on MHD Flow and Heat Transfer over an Exponentially Stretching Sheet with Viscous Dissipation and Radiation Effects

This study is to examine the steady two dimensional laminar flow of a viscous incompressible electrically conducting fluid over a continuous surface. In this study DTM-Pade method is used to solve which is a combination of differential transform method (DTM) and Pade approximant. Comparisons between the solutions obtained by DTM and DTM-Pade and are shown that DTM-Pade is the completely powerful method then DTM for solving the problems in which boundary conditions at infinity. Also in this study the effect of Magnetic and Radiation parameters, Prandtl number and Eckert number for velocity and temperature distributions are investigated.
Parallel second-order tensors on Vaisman manifolds

The aim of this paper is to study the class of parallel tensor fields α of (0, 2)-type in a Vaisman geometry (M,J,g). A sufficient condition for the reduction of such symmetric tensors α to a constant multiple of g is given by the skew-symmetry of α with respect to the complex structure J. As an application of the main result, we prove that certain vector fields on a P0K-manifold turn out to be Killing. Also, we connect our main result with the Weyl connection of conformal geometry as well as with possible Ricci solitons in P0K manifolds.
IMPACT OF IRRIGATION INTERVALS ON PRODUCTIVITY OF SESAME UNDER SOUTHERN EGYPT CONDITIONS

The effect of irrigation regimes on yield, yield attributes and IWUE of two sesame cultivars (Giza 32 and Toushki 3) was assessed. A field experiment was carried out in the Experimental Farm of the Faculty of Agriculture, South Valley University at Qena during two years on a sandy soil. A randomized complete block design in split plot arrangement with three replicates was used in this study. Irrigation treatments were randomly assigned to the main plots and the two cultivars were assigned to the split plots. The studied irrigation regimes affected significantly plant height, fruiting zone length, number of fruiting branches plant-1, number of capsules plant-1, 1000-seed weight, seed weight plant-1 and seed and oil yields ha-1. The highest values of the studied characteristics were recorded under high regime (irrigation every 7 days) or medium regime (irrigation every 9 days). The highest value of IWUE was obtained from medium regime. Giza 32 cv. overcame significantly Toushki 3 cv. in seed yield, yield attributes, IWUE and seed oil percentage, while seeds of Toushki 3 were richer in protein content (%). According to the results of seed and oil yields ha-1 and IWUE, it is recommended to apply medium irrigation regime (8883 m3 ha-1). In addition, growing sesame Giza 32 cv. is recommended under similar soil and climatic conditions.
MM-Tap: Adaptive and Scalable Tap Localization on Ubiquitous Surfaces With mm-Level Accuracy

Transforming physical surfaces into virtual interfaces can extend the interaction capability of many exciting metaverse applications in the future. Recent advances in vibration-based tap sensing show promise for this vision using passive vibration signals. However, current approaches based on Time-Difference-of-Arrival (TDoA) triangulation suffer the impact of fluctuant wave velocity due to the dispersive and heterogeneous nature of solid mediums, failing to meet the performance requirement for practical use. In this article, we present MM-Tap, a vibration-based tap localization system that can transform ubiquitous surfaces into virtual touch screens with low overhead. A novel localization scheme is proposed based on the finding of spatiotemporal mapping between tap locations and TDoA values, which pushes the accuracy limits of vibration-based tap sensing from unstable cm-level to mm-level. We investigate the geometry of the sensor layout and design a model-based method to synthesize tap data, which enables MM-Tap to adapt to various surface materials and respond to arbitrary sensing scales after a few seconds of calibration. We combine MM-Tap with a COTS projector and facilitate a digitally augmented surface where users can play video games with low latency.
On the Hamilton–Waterloo problem with odd cycle lengths

Let Kv∗ denote the complete graph Kv if v is odd and Kv−I , the complete graph with the edges of a 1‐factor removed, if v is even. Given nonnegative integers v,M,N,α,β , the Hamilton–Waterloo problem asks for a 2‐factorization of Kv∗ into α CM ‐factors and β CN ‐factors, with a Cℓ ‐factor of Kv∗ being a spanning 2‐regular subgraph whose components are ℓ‐cycles. Clearly, M,N≥3 , M∣v , N∣v and α+β=⌊v−12⌋ are necessary conditions. In this paper, we extend a previous result by the same authors and show that for any odd v≠MNgcd(M,N) the above necessary conditions are sufficient, except possibly when α=1 , or when β∈{1,3} . Note that in the case where v is odd, M and N must be odd. If M and N are odd but v is even, we also show sufficiency but with further possible exceptions. In addition, we provide results on 2‐factorizations of the complete equipartite graph and the lexicographic product of a cycle with the empty graph.
A Novel Linear-Model-Based Methodology for Predicting the Directional Movement of the Euro-Dollar Exchange Rate

Predicting the price and trends of financial instruments is a major challenge in the financial industry, impacting investment decision-making efficiency for various stakeholders. Although numerous and effective artificial intelligence techniques have been applied to time series analysis, the prediction of exchange rate movements in the Forex market still necessitates parsimonious, interpretable, and accurate solutions. This paper presents a novel methodology for predicting the short-term directional movement of the euro-dollar exchange rate using market data, specifically by measuring price action. The proposed methodology prioritizes using market inflection points and the multidimensional nature of the differences between uptrends and downtrends to construct a linear discriminant function (LDA). The core of our methodology is our novel Linear Classifier Configurator (LCC) which includes stages for data preparation, feature selection, and detection of underlying structures. We validate the results and interpretations using the statistical power of parametric tests. The experiments use market data of the euro-dollar exchange rate in 15-minute and 1-week time frames. Additionally, we incorporate a collection of intraday winning trades provided by an algorithmic trading model applied between January 1999 and April 2023. The proposed LCC methodology achieves an out-of-sample classification accuracy of 98.77%, outperforming other methodologies based on sophisticated approaches such as Long Short-Term Memory (LSTM), Deep reinforcement learning (DRL), Wavelet analysis (WA), Sentiment analysis of textual content, Support Vector Machines (SVM), and Genetic Algorithms (GA). Furthermore, our methodology improves financial performance and reduces risk exposure in trading strategies, as well as it is useful in selecting variables and transferable to other financial assets.
COMPARISON OF HOMOGENEOUS REGIONS OF PRECIPITATION FROM TWO DISTINCT DATA SOURCE FOR THE STATE OF PARÁ-BRAZIL

: The aim of this study was to compare the regionalization of precipitation carried out using the Fuzzy C-Means grouping technique, with two distinct data sources, one provided by the National Water Agency (ANA) and the other obtained through the Global Precipitation Climatology Centre (GPCC) meteorological satellite provided by the German National Meteorological Service (DWD), for 30 years (1986 to 2015), with the aim of verifying through statistical techniques, what will be the representativeness and differences of the regions formed by traditional and satellite. The non-hierarchical technique of Fuzzy C-Means was applied to the formation of the regions for the two data, in order to group the stations, later owned by the groupings, validation techniques (Dunn, Silhouette and PBM) were applied, with the aim of forming the best cluster for data analysis. Performance analyses were also performed, using statistical methods. As results, 2 homogeneous rainfall regions were found after the calculations of the validation indices, in which they were
Quantum order, entanglement and localization in many-body systems

The interplay of disorder and interactions can have remarkable effects on the physics of quantum systems. A striking example is provided by the long conjectured—and recently confirmed—phenomenon of many-body localization. Many-body localized (MBL) phases violate foundational assumptions about ergodicity and thermalization in interacting systems, and represent a new frontier for non-equilibrium quantum statistical mechanics. We start with a study of the dynamical response of MBL phases to time-dependent perturbations. We find that that an asymptotically slow, local perturbation induces a highly non-local response, a surprising result for a localized insulator. A complementary calculation in the linear-response regime elucidates the structure of many-body resonances contributing to the dynamics of this phase We then turn to a study of quantum order in MBL systems. It was shown that localization can allow novel high-temperature phases and phase transitions that are disallowed in equilibrium. We extend this idea of “localization protected order” to the case of symmetry-protected topological phases and to the elucidation of phase structure in periodically driven Floquet systems. We show that Floquet systems can display nontrivial phases, some of which show a novel form of correlated spatiotemporal order and are absolutely stable to all generic perturbations. The next part of the thesis addresses the role of quantum entanglement, broadly speaking. Remarkably, it was shown that even highly-excited MBL eigenstates have low area-law entanglement. We exploit this feature to develop tensor-network based algorithms for efficiently computing and representing highly-excited MBL eigenstates. We then switch gears from disordered, localized systems and examine the entanglement Hamiltonian and its low energy spectrum from a statistical mechanical lens, particularly focusing on issues of universality and thermalization.
