description: Some proposals to account for the highest energy cosmic rays predict that they should point to their sources. We study the five highest energy events (E>10^20 eV) and find they are all aligned with compact, radio-loud quasars. The probability that these alignments are coincidental is 0.005, given the accuracy of the position measurements and the rarity of such sources. The source quasars have redshifts between 0.3 and 2.2. If the correlation pointed out here is confirmed by further data, the primary must be a new hadron or one produced by a novel mechanism.

description: We study a family of symmetric functions $\hat F_z$ indexed by involutions $z$ in the affine symmetric group. These power series are analogues of Lam's affine Stanley symmetric functions and generalizations of the involution Stanley symmetric functions introduced by Hamaker, Pawlowski, and the first author. Our main result is to prove a transition formula for $\hat F_z$ which can be used to define an affine involution analogue of the Lascoux-Schützenberger tree. Our proof of this formula relies on Lam and Shimozono's transition formula for affine Stanley symmetric functions and some new technical properties of the strong Bruhat order on affine permutations.

description: In this paper, we describe DeFactoNLP, the system we designed for the FEVER 2018 Shared Task. The aim of this task was to conceive a system that can not only automatically assess the veracity of a claim but also retrieve evidence supporting this assessment from Wikipedia. In our approach, the Wikipedia documents whose Term Frequency-Inverse Document Frequency (TFIDF) vectors are most similar to the vector of the claim and those documents whose names are similar to those of the named entities (NEs) mentioned in the claim are identified as the documents which might contain evidence. The sentences in these documents are then supplied to a textual entailment recognition module. This module calculates the probability of each sentence supporting the claim, contradicting the claim or not providing any relevant information to assess the veracity of the claim. Various features computed using these probabilities are finally used by a Random Forest classifier to determine the overall truthfulness of the claim. The sentences which support this classification are returned as evidence. Our approach achieved a 0.4277 evidence F1-score, a 0.5136 label accuracy and a 0.3833 FEVER score.

description: A single-electron inverter was fabricated that switches from a high output to a low output when a fraction of an electron is added to the input. For the proper operation of the inverter, the two single-electron transistors that make up the inverter must exhibit voltage gain. Voltage gain was achieved by fabricating a combination of parallel-plate gate capacitors and small tunnel junctions in a two-layer circuit. Voltage gain of 2.6 was attained at 25 mK and remained larger than one for temperatures up to 140 mK. The temperature dependence of the gain agrees with the orthodox theory of single-electron tunneling.

description: We study influence of noncommutativity of coordinates and noncommutativity of momenta on the motion of a particle (macroscopic body) in uniform and non-uniform gravitational fields in noncommutative phase space of canonical type with preserved rotational symmetry. It is shown that because of noncommutativity the motion of a particle in gravitational filed is determined by its mass. The trajectory of motion of a particle in uniform gravitational field corresponds to the trajectory of harmonic oscillator with frequency determined by the value of parameter of momentum noncommutativity and mass of the particle. The equations of motion of a macroscopic body in gravitational filed depend on its mass and composition. From this follows violation of the weak equivalence principle caused by noncommutativity. We conclude that the weak equivalence principle is recovered in rotationally invariant noncommutative phase space if we consider the tensors of noncommutativity to be dependent on mass. So, finally we construct noncommutative algebra which is rotationally invariant, equivalent to noncommutative algebra of canonical type, and does not lead to violation of the weak equivalence principle.

description: The equations of state at room temperature as well as the energies of crystal structures up to pressures exceeding 100 GPa are calculated for Na and K . It is shown that the allowance for generalized gradient corrections (GGA) in the density functional method provides a precision description of the equation of state for Na, which can be used for the calibration of pressure scale. It is established that the close-packed structures and BCC structure are not energetically advantageous at high enough compressions. Sharply non-monotonous pressure dependences of elastic moduli for Na and K are predicted and melting temperatures at high pressures are estimated from various melting criteria. The phase diagram of K is calculated and found to be in good agreement with experiment.

description: We consider the action principle to derive the classical, non-relativistic motion of a self-interacting particle in a 4-D Lorentzian spacetime containing a wormhole and which allows the existence of closed time-like curves. For the case of a `hard-sphere' self-interaction potential we show that the only possible trajectories (for a particle with fixed initial and final positions and which traverses the wormhole once) minimizing the classical action are those which are globally self-consistent, and that the `Principle of self-consistency' (originally introduced by Novikov) is thus a natural consequence of the `Principle of minimal action.'

description: Teaching English as a Foreign Language requires more than just imparting linguistic skills; it involves fostering a learning environment where all students feel respected and understood. Cultural sensitivity is an essential component in this process, as it helps educators to recognize the unique challenges and perspectives that come with teaching a diverse group of learners. Understanding the cultural nuances and backgrounds of students can lead to more effective teaching methods, tailored lesson plans, and improved student engagement. Moreover, it helps in building a strong teacher-student relationship based on trust and mutual respect. By being culturally sensitive, teachers can address and mitigate any biases or prejudices that may inadvertently arise in the classroom, ensuring that all students have equal opportunities to succeed. In essence, cultural sensitivity not only enriches the teaching and learning experience but also prepares students to navigate and thrive in a multicultural world.

description: For a class of non-autonomous parabolic stochastic partial differential equations defined on a bounded open subset $D\subset \mathbb {R}^d$ and driven by an $L^2(D)$-valued fractional Brownian motion with the Hurst index $H>1/2$, a new result on existence and uniqueness of a mild solution is established. Compared to the existing results, the uniqueness in a fully nonlinear case is shown, not assuming the coefficient in front of the noise to be affine. Additionally, the existence of moments for the solution is established.

description: We study several problems concerning convex polygons whose vertices lie in a Cartesian product of two sets of $n$ real numbers (for short, \emph{grid}). First, we prove that every such grid contains $Ω(\log n)$ points in convex position and that this bound is tight up to a constant factor. We generalize this result to $d$ dimensions (for a fixed $d\in \mathbb{N}$), and obtain a tight lower bound of $Ω(\log^{d-1}n)$ for the maximum number of points in convex position in a $d$-dimensional grid. Second, we present polynomial-time algorithms for computing the longest $x$- or $y$-monotone convex polygonal chain in a grid that contains no two points with the same $x$- or $y$-coordinate. We show that the maximum size of a convex polygon with such unique coordinates can be efficiently approximated up to a factor of $2$. Finally, we present exponential bounds on the maximum number of point sets in convex position in such grids, and for some restricted variants. These bounds are tight up to polynomial factors.

description: A comprehensive theory is presented for the voltage, temperature, and spatial dependence of the tunneling current between a scanning tunneling microscope (STM) tip and a metallic surface with an individual magnetic adatom. Modeling the adatom by a nondegenerate Anderson impurity, a general expression is derived for a weak tunneling current in terms of the dressed impurity Green function, the impurity-free surface Green function, and the tunneling matrix elements. This generalizes Fano's analysis to the interacting case. The differential-conductance lineshapes seen in recent STM experiments with the tip directly over the magnetic adatom are reproduced within our model, as is the rapid decay, \sim 10Å, of the low-bias structure as one moves the tip away from the adatom. With our simple model for the electronic structure of the surface, there is no dip in the differential conductance at approximately one lattice spacing from the magnetic adatom, but rather we see a resonant enhancement. The formalism for tunneling into small clusters of magnetic adatoms is developed.

description: The main goal of this thesis is to unveil some questions related to the formation of complex fullerene-based molecules in space, with the aim of resolving some key problems in astrophysics. The unexpected detections of fullerenes and graphene (possible C24) in the H-rich circumstellar environments of evolved stars indicate that these complex molecules are not so rare and bring the idea that other forms of carbon such as hydrogenated fullerenes (fulleranes), buckyonions, and carbon nanotubes may be widespread in the Universe, being closely involved in many aspects of circumstellar/interstellar chemistry and physics. We explore this new and fertile field of research by focusing our study on some Galactic planetary nebulae (PNe) that contain fullerenes. In order to do this, we make use of laboratory spectra of several fullerene-related compounds and compare them with astronomical data. This work is a first step to open up a new field of interdisciplinary research, crossing the boundaries between astronomers, chemists, and physicists, and understand the significant presence of fullerene structures in circumstellar/interstellar environments.

description: This study explored the relationship between artificial intelligence and sustainable development of hospitality sector in Southeast, Nigeria. Specifically, the study determined the relationship between alexa and community engagement of hospitality sector in Southeast, Nigeria. Also, it ascertained the relationship between chatbot and capacity building of hospitality sector in Southeast, Nigeria. The study is anchored on Fourth Industrial Revolution (4IR) theory by Klaus Schwab in 2016. The study employed descriptive survey research design and random sampling probability technique. The population of the study was 304. Hypotheses were tested with Pearson Product Moment Correlation Coefficient with the aid of Statistical Package for Social Sciences (SPSS, version 27). Hypothesis one indicated that there is a statistically significant positive relationship between alexa and community engagement of hospitality sector in Southeast, Nigeria, with r = 0.782, n = 304 and p value of 0.000 (p<0.05). Hypothesis two revealed that there is a statistically positive significant correlation between chatbot and capacity building of hospitality sector in Southeast, Nigeria, with r = 0.923, n = 304 and p value of 0.000 (p<0.05). The study concluded that there is a positive and statistically significant relationship between artificial intelligence and sustainable development of hospitality sector in Southeast, Nigeria. The study recommended that hospitality sector in Southeast, Nigeria, need to leverage chatbot technology to support and enhance capacity building initiatives, leading to improved skills and performance. Also, government needs to prioritize the design and development of user-friendly and interactive technologies to enhance community engagement and participation of hospitality industries sector in Southeast, Nigeria
Mathematical Structures of Space-Time

description: At first we introduce the space-time manifold and we compare some aspects of Riemannian and Lorentzian geometry such as the distance function and the relations between topology and curvature. We then define spinor structures in general relativity, and the conditions for their existence are discussed. The causality conditions are studied through an analysis of strong causality, stable causality and global hyperbolicity. In looking at the asymptotic structure of space-time, we focus on the asymptotic symmetry group of Bondi, Metzner and Sachs, and the b-boundary construction of Schmidt. The Hamiltonian structure of space-time is also analyzed, with emphasis on Ashtekar's spinorial variables. Finally, the question of a rigorous theory of singularities in space-times with torsion is addressed, describing in detail recent work by the author. We define geodesics as curves whose tangent vector moves by parallel transport. This is different from what other authors do, because their definition of geodesics only involves the Christoffel symbols, though studying theories with torsion. We then prove how to extend Hawking's singularity theorem without causality assumptions to the space-time of the ECSK theory. This is achieved studying the generalized Raychaudhuri equation in the ECSK theory, the conditions for the existence of conjugate points and properties of maximal timelike geodesics. Our result can also be interpreted as a no-singularity theorem if the torsion tensor does not obey some additional conditions. Thus, it seems that the occurrence of singularities in closed cosmological models based on the ECSK theory is less generic than in general relativity. Our work should be compared with important previous papers. There are some relevant differences, because we rely on a different definition of

Brenan argued that this material conflicts with the diagnosis, and rejected de Wit’s choice in favour of the Dillenius plate. However, Reveal (in Taxon 41: 138. 1992) proposed the name, and the type accepted by Brenan and others, for conservation. The Committee for Spermatophyta (in Taxon 43: 273. 1994) did not recommend this, accepting Brenan’s choice of type as valid. Conservation was therefore felt to be unnecessary.

description: We study massive Dirac fields in the background of the near-horizon limit of the extremal Myers-Perry black hole in five dimensions. We consider the case in which both angular momenta have equal magnitude. The resulting Dirac equation can be decoupled into an angular and a radial part. The solution of the angular part results in some algebraic relations that determine completely the angular quantum numbers of the fermionic field. The radial part can be analytically solved in terms of special functions, which allow us to analyze the near-horizon radial current of the Dirac field.

description: The effective action of a Higgs theory should be gauge-invariant. However, the quantum and/or thermal contributions to the effective potential seem to be gauge-dependent, posing a problem for its physical interpretation. In this paper, we identify the source of the problem and argue that in a Higgs theory, perturbative contributions should be evaluated with the Higgs fields in the polar basis, not in the Cartesian basis. Formally, this observation can be made from the derivation of the Higgs theorem, which we provide. We show explicitly that, properly defined, the effective action for the Abelian Higgs theory is gauge invariant to all orders in perturbation expansion when evaluated in the covariant gauge in the polar basis. In particular, the effective potential is gauge invariant. We also show the equivalence between the calculations in the covariant gauge in the polar basis and the unitary gauge. These points are illustrated explicitly with the one-loop calculations of the effective action. With a field redefinition, we obtain the physical effective potential. The SU(2) non-Abelian case is also discussed.

Exploring the biases of a new method based on minimum variance for interplanetary magnetic clouds

description: Magnetic clouds (MCs) are twisted magnetic structures ejected from the Sun and probed by in situ instruments. They are typically modeled as flux ropes (FRs). The determination of the FR global characteristics requires the estimation of the FR axis orientation. Among the developed methods, the minimum variance (MV) is the most flexible, and features only a few assumptions. However, as other methods, MV has biases. We aim to investigate the limits of the method and extend it to a less biased method. We first identified the origin of the biases by testing the MV method on cylindrical and elliptical models with a temporal expansion comparable to the one observed in MCs. Then, we developed an improved MV method to reduce these biases. In contrast with many previous publications we find that the ratio of the MV eigenvalues is not a reliable indicator of the precision of the derived FR axis direction. Next, we emphasize the importance of the FR boundaries selected since they strongly affect the deduced axis orientation. We have improved the MV method by imposing that the same amount of azimuthal flux should be present before and after the time of closest approach to the FR axis. We emphasize the importance of finding simultaneously the FR axis direction and the location of the boundaries corresponding to a balanced magnetic flux, so as to minimize the bias on the deduced FR axis orientation. This method can also define an inner flux-balanced sub-FR. We show that the MV results are much less biased when a compromise in size of this sub-FR is achieved. For weakly asymmetric field temporal profiles, the improved MV provides a very good determination of the FR axis orientation. The main remaining bias is moderate (lower than 6 degrees) and is present mostly on the angle between the flux rope axis and the plane perpendicular to the Sun-Earth direction.

Constraining Inflation with Cosmic Microwave Background Polarization

description: Observations of the polarization of the cosmic microwave backround (CMB) have the potential to place much tighter constraints on cosmological parameters than observations of the fluctuations in temperature alone. We discuss using CMB polarization to constrain parameters relevant for distinguishing among popular models for cosmological inflation, using the MAP and Planck satellite missions as example cases. Of particular interest is the ability to detect tiny contributions to the CMB anisotropy from tensor modes, which is fundamentally limited by cosmic variance in temperature-only observations. The ability to detect a tensor/scalar ratio $r \sim 0.01$ would allow precision tests of interesting inflation models, and is possible with a modest increase in sensitivity over that planned for the Planck satellite, or potentially by ground-based experiments.

Disorder-induced critical behavior in driven diffusive systems

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Using dynamic renormalization group we study the transport in driven diffusive systems in the presence of quenched random drift velocity with long-range correlations along the transport direction. In dimensions $d\mathopen< 4$ we find fixed points representing novel universality classes of disorder-dominated self-organized criticality, and a continuous phase transition at a critical variance of disorder. Numerical values of the scaling exponents characterizing the distributions of relaxation clusters are in good agreement with the exponents measured in natural river networks.

 Lectotype (Reveal in Phytologia 71: 453, 454. 1991): Herb. Clifford: 159, Cassia 7, sheet 10 (BM-000558727).
 Current name:  Senna occidentalis  (L.) Link (Fabaceae: Caesalpinioideae).
 Note: De Wit (in Webbia 11: 257. 1956) indicated 528.13 (LINN) as the holotype but it is a Patrick Browne collection, not received by Linnaeus until 1758 and not original material for the name. Others, including Wijnands (Bot. Commelins: 60. 1983), treated this collection as a neotype but this is unacceptable because original elements are in existence. Brenan (in Milne-Redhead & Polhill, Fl. Trop. E. Africa, Leguminosae 2: 78 (1967), followed by many authors, treated a Clifford sheet (BM) as a syntype, but in any case did not distinguish between the two sheets that exist. Some authors have attributed a formal type choice to Brenan (e.g. Irwin & Barneby in Mem. New York Bot. Gard. 35: 436. 1982. as “lectoholotypus”) but still fail to distinguish between the sheets. Reveal subsequently provided a detailed review, and designated one of them as the lectotype.

description: Current authentication methods on the Web have serious weaknesses. First, services heavily rely on the traditional password paradigm, which diminishes the end-users' security and usability. Second, the lack of attribute-based authentication does not allow anonymity-preserving access to services. Third, users have multiple online accounts that often reflect distinct identity aspects. This makes proving combinations of identity attributes hard on the users. In this paper, we address these weaknesses by proposing a privacy-preserving architecture for device-centric and attribute-based authentication based on: 1) the seamless integration between usable/strong device-centric authentication methods and federated login solutions; 2) the separation of the concerns for Authorization, Authentication, Behavioral Authentication and Identification to facilitate incremental deployability, wide adoption and compliance with NIST assurance levels; and 3) a novel centralized component that allows end-users to perform identity profile and consent management, to prove combinations of fragmented identity aspects, and to perform account recovery in case of device loss. To the best of our knowledge, this is the first effort towards fusing the aforementioned techniques under an integrated architecture. This architecture effectively deems the password paradigm obsolete with minimal modification on the service provider's software stack.

WASTE POLYPROPYLENE CEMENT BAG MATERIAL FOR EXPANSIVE SOIL STABILIZATION AT KOYE FECHE III SITE
Creators: name: MERON GIZAW
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019
Subjects: Stabilization, Polypropylene cement bag, Unconfined compressive strength, Swelling pressure, Random orientation

description: This study assesses stabilization of expansive soil found in Koye Feche III site. Soil samples were collected at three different locations and test pits named: TP-1, TP-2 and TP-3. The improvement of strength in expansive soil with addition of fibre extracted from waste polypropylene cement bag in various percentages with different lengths of fibres, was evaluated through a series of unconfined compressive strength and swelling pressure tests.
 The fibres were added in percentages of 0, 0.5, 1 and 1.5 by weight of dry soil in random orientation. Fibres were used in 12 mm and 20 mm lengths. It was found that with the increase in fibre proportions there was improvement in unconfined compressive strength and reduction in swelling pressure with the maximum effects being observed at 1.5% fiber content. It was also found that the increase in the length of fibre showed an increase in the unconfined compressive strength and reduction in swelling pressure of the soil.
