description: A general method to study classical scattering in $n$-dimension is developed. Through classical trajectory calculations, the three-body recombination is computed as a function of the collision energy for helium atoms, as an example. Quantum calculations are also performed for the $J^Π$ = $0^{+}$ symmetry of the three-body recombination rate in order to compare with the classical results, yielding good agreement for $E\gtrsim$ 1 K. The classical threshold law is derived and numerically confirmed for the Newtonian three-body recombination rate. Finally, a relationship is found between the quantum and classical three-body hard hypersphere elastic cross sections which is analogous to the well-known shadow scattering in two-body collisions.

Implosives in Bantu A80? The case of Gyeli
Creators: name: Grimm, Nadine
Publisher: name: Zenodo
Year: 2019

description: Implosive consonants in Bantu A80 languages are widely attested in the litera-
 ture. The status that specific authors assign to them, however, differ significantly,
 ranging from mere phonetic contrasts to phonemic status or even absence in cer-
 tain languages. Given this variety of language analyses, along with a controversy
 about necessary and sufficient features of implosive sounds, this paper aims at re-
 assessing the range of implosives and non-implosives within A80 and especially
 Gyeli (A801). I show that though implosives are expected in Gyeli from previous
 literature, these sounds are better described as pre-glottalized stops with a rela-
 tively long prevoicing time. That raises the question whether this analysis might
 be more appropriate for other A80 languages as well. While this paper cannot pro-
 vide any conclusive answer on the latter question, it hopes to raise awareness of
 the methodological problems associated with the present description of A80 im-
 plosives, encouraging a systematic re-evaluation of the data. It also encourages a
 discussion on how the general fieldworker should go about describing implosive(-
 like) sounds.
The Effect of Promotion Practices on Consumer’s Purchase Decision: The Case of Some Selected Real Estates in Addis Ababa, Ethiopia
Creators: name: Maiden Worku, Mohammed Mohammednur
Publisher: name: Journal of Business and Administrative Studies
Year: 2023

description: This study is intended to measure the effect of the five promotional elements such as sales promotion, personal selling, direct marketing, advertising, and public relation practiced in the real estate industry on the purchase decision of customers. A combination of descriptive and explanatory research design was used with a quantitative research approach. Primary data were collected using survey questionnaire distributed to 322 sampled respondents. Data were subjected to inferential statistical methods supported with SPSS software. The results of the analysis revealed that all the variables (such as sales promotion, personal selling, direct marketing, advertising, and public relation) have direct correlation with the customer’s purchase decision at p<0.05. All the variables jointly explained purchase decision of real estate consumers by 53.2%. The regression’s result showed that, except advertisement practice, the other four promotional elements were statistically significant in affecting purchase decision of consumers.

Reconsidering tone and melodies in Kikamba
Creators: name: Jones, Patrick
name: Freyer, Jake
Publisher: name: Zenodo
Year: 2019

description: The melodic tone system of Kikamba, as described by Roberts-Kohno (2000; 2014),
 stands out as particularly complex within the context of recent crosslinguistic
 work on melodic tone in Bantu (Odden & Bickmore 2014; Bickmore 2015). It is
 unique, for example, in possessing a melody that assigns four distinct tones to
 three stem-internal positions simultaneously. The apparent existence of such com-
 plex melodies raises doubts as to whether there are any substantive restrictions
 on the possible form of a tonal melody. We argue, however, that these doubts are
 premature. We propose a new analysis of Kikamba in which (a) melodies refer
 to no more than two target positions at a time and (b) melodies target only two
 possible stem-internal positions, each of which occurs commonly within Bantu
 melodic tone systems. This simplification is achieved by (a) rejecting the existence
 of a melodic L tone assigned to the penult, and attributing its putative effects to in-
 teractions among other, more basic tones, and (b) distinguishing between melodic
 tones assigned early in the phonological derivation and other suffixal tones added
 later. In general, we argue that since core properties of melodic tone are often
 obscured in surface forms due to interactions with language-particular rules, the
 crosslinguistic comparison of melodic tone should proceed on the basis of a (more)
 underlying level in which these rules are controlled for. Once this is done, the ex-
 ceptional properties of Kikamba melodic tone largely disappear.
The Determinants of Choice of Transportation Mode in Addis Ababa, Ethiopia

Year: 2023

description: This study is designed to investigate the determinants of choice of transport mode in Addis Ababa. It adopted a cross-sectional research design and collected quantitative data from 141 respondents that used different transport modes. A multinomial logit model was adopted to identify the determinants of choice of transport modes. About 54% of the city’s dwellers used taxi (popularly known as ‘’Blue minibus taxi’’), and 25% of them used buses. The proportion of dwellers who chose to use train transport method and private cars are equal (10.5% each). Blue minibus taxi are the dominant mode of transport used in the city of Addis Ababa. The results of the multinomial logit model revealed that traveler’s characteristics (age, family size, income, occupation, and educational level) and mode of transport characteristics (travel time, travel cost, travel distance, comfort, accessibility, safety, and security) were found to be statistically significant in determining choice of a transport mode. The city government of Addis Ababa should therefore take into account the significant correlates in deciding to improve the transportation system of the City..

description: We study electron transport in composite ferroelectrics --- materials consisting of metallic grains embedded in a ferroelectric matrix. Due to its complex tunable morphology the thermodynamic properties of these materials can be essentially different from bulk or thin-film ferroelectrics. We calculate the conductivity of composite ferroelectrics by taking into account the interplay between charge localization, multiple grain boundaries, strong Coulomb repulsion, and ferroelectric order parameter. We show that the ferroelectricity plays a crucial role on the temperature behavior of the conductivity in the vicinity of the ferroelectric-paraelectric transition.

description: In this paper, we present pilot data from a small number of native speakers of Somali, investigating the acoustic correlates of the tongue root and/or voice quality feature relevant to vowel harmony in that language. We find statistically detectable differences along the predicted acoustic dimensions (on the basis of previous articulatory descriptions), and use Linear Discriminant Analysis (LDA) to extend classifications to previously-uncategorized items. However, we find no clear evidence that these differences are categorical or phonological.
Robust Computation of Dipole Electromagnetic Fields in Arbitrarily-Anisotropic, Planar-Stratified Environments

description: We develop a general-purpose formulation, based on two-dimensional spectral integrals, for computing electromagnetic fields produced by arbitrarily-oriented dipoles in planar-stratified environments, where each layer may exhibit arbitrary and independent anisotropy in both the (complex) permittivity and permeability. Among the salient features of our formulation are (1) computation of eigenmodes (characteristic plane waves) supported in arbitrarily anisotropic media in a numerically robust fashion, (2) implementation of an hp-adaptive refinement for the numerical integration to evaluate the radiation and weakly-evanescent spectra contributions, and (3) development of an adaptive extension of an integral convergence acceleration technique to compute the strongly-evanescent spectrum contribution. While other semianalytic techniques exist to solve this problem, none have full applicability to media exhibiting arbitrary double anisotropies in each layer, where one must account for the whole range of possible phenomena such as mode coupling at interfaces and non-reciprocal mode propagation. Brute-force numerical methods can tackle this problem but only at a much higher computational cost. The present formulation provides an efficient and robust technique for field computation in arbitrary planar-stratified environments. We demonstrate the formulation for a number of problems related to geophysical exploration.

description: The aim of this study is to exhibit the mutual connection between surface and in depth hardness values in the case of surface-treated metal samples with inhomogeneous hardness distribution in the surface layer. The reason for surface treatments of metal alloys is most commonly to increase the hardness and wear resistance at the surface. Case depth, as a result of surface treatment and the in-depth hardness distribution, can be determined by measuring the hardness of a section perpendicular to the treated surface and by metallographic examination. The result of heat treatment can also be checked rapidly by surface hardness testing. Surface hardness carries only indirect information regarding case depth and hardness distribution. Surface and cross-sectional hardness can be related to the mathematical modeling of the plastic zone developing in the indentation process. The mathematical model applied in this study allows the conversion of the surface hardness function into the in-depth hardness function and vice-versa. The calculation method presented was validated by analyzing the hardness data of nitrocarburized samples of various case depths. The validation result proves that cross-sectional hardness distribution can be adequately estimated by surface hardness data in the case of a surface layer with monotonically decreasing hardness distribution.
Prosody and the conjoint disjoint alternation in Tshivenḓa
Creators: name: Kusmer, Leland Paul
Publisher: name: Zenodo
Year: 2019

description: Tshivenḓa (Guthrie S21) shares with other Southern Bantu languages a distinctive alternation in the form of the verb, termed the conjoint\slash disjoint alternation. I will present data from original fieldwork showing that, in contrast to other related languages, the Tshivenḓa conjoint and disjoint forms are not in complementary distribution by syntactic context, and instead show a distinctive three-way split in acceptability. I will also show that the same three-way split obtains in the frequency of utterance-internal penultimate lengthening. I discuss two possible analyses of this correlation, one in which the disjoint is a purely prosodic phenomenon and one in which the correlation is due to the influence of some third factor such as information structure.

description: We propose to engineer time-reversal-invariant topological insulators in two-dimensional (2D) crystals of transition metal dichalcogenides (TMDCs). We note that, at low doping, semiconducting TMDCs under shear strain will develop spin-polarized Landau levels residing in different valleys. We argue that gaps between Landau levels in the range of $10-100$ Kelvin are within experimental reach. In addition, we point out that a superlattice arising from a Moiré pattern can lead to topologically non-trivial subbands. As a result, the edge transport becomes quantized, which can be probed in multi-terminal devices made using strained 2D crystals and/or heterostructures. The strong $d$ character of valence and conduction bands may also allow for the investigation of the effects of electron correlations on the topological phases.

The phonetics and phonology of depressor consonants in Gengbe
Creators: name: Lotven, Samson

Publisher: name: Zenodo
Year: 2019

description: The interaction between initial voiced obstruents and lower f0 has been noted for
 a variety of languages (Chistovich 1969; Stevens & Klatt 1973; Bradshaw 1999; Tang
 2008, to name a few). In some languages, phonetic consonant-f0 interactions that
 alter f0 register and/or contour can be phonologized as consonant-tone interac-
 tions (Maran 1973; Matisoff 1973). In Gengbe, a Gbe language spoken in Southern
 Togo and Benin, obstruent voicing displays several interactions with f0 register
 and contour. The goal of this study is to present the synchronic system of Gengbe
 consonant-f0 interactions with an eye toward the larger question of phonologiza-
 tion. This paper presents both phonetic and phonological data for discussion. Pre-
 liminary acoustic data suggest initial voiced obstruents lower the register f0 of fol-
 lowing Low and High tone vowels. Phonological data suggest that tonal contour
 effects, which change underlying High tone to Rising tone in some environments,
 vary based on syntactic category – voiced obstruents trigger Rising tone in nouns,
 while voiced obstruents and sonorants trigger Rising tone in verbs. This paper of-
 fers a snapshot of a system where at least some consonant-f0 interactions have
 been phonologized, adding to the broader understanding of tonogenetic processes.

description: In order to study partial restoration of the chiral symmetry at finite density, we investigate the density corrections of the chiral condensate up to next-leading order of density expansion using the chiral Ward identity and an in-medium chiral perturbation theory. In our study, we assume that all the in-vacuum quantities for the pion, the nucleon and the pi N interaction are determined and focus on density expansion of the in-medium physical quantities. We perform diagrammatic analysis of the correlation functions which provide the in-medium chiral condensate. This density expansion scheme shows that medium effects to the chiral condensate beyond the linear density come from density corrections to the pi N sigma term as a result of the interactions between pion and nucleon in nuclear matter. We also discuss that higher density contributions beyond order of rho^2 cannot be fixed only by the in-vacuum pi N dynamics but we need NN two-body dynamics in vacuum to fix divergence appearing in the calculation of the rho^2 dependence of the chiral condensate with the pi N dynamics.

description: Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental risks of the spent catalysts. This study evaluates the different chemical fractions/forms of aluminium (Al), nickel (Ni) and molybdenum (Mo) in spent hydroprocessing catalyst and the changes they undergo during bioleaching with Acidithiobacillus ferrooxidans. In the spent catalyst (prior to bioleaching), Al was primarily present in its residual form, suggesting its low environmental mobility. However, Ni comprised mainly an exchangeable fraction, indicating its high environmental mobility. Molybdenum was mainly in the oxidizable form (47.1%), which indicated that highly oxidizing conditions were required to liberate it from the spent catalyst. During bioleaching the exchangeable, reducible and oxidizable fractions of all the metals were leached, whereas the residual fractions remained largely unaffected. At the end of bioleaching process, the metals remaining in the bioleached sample were predominantly in the residual fraction (98.3-99.5%). The risk assessment code (RAC) and IR analysis also demonstrated that the environmental risks of the bioleached residue was significantly lower compared to the untreated spent catalyst. The results of the current study suggest that bioleaching is an effective method in removing the metals from spent catalysts and the bioleached residue poses little environmental risk.

description: We investigate the fidelity susceptibility (FS) of a two-dimensional spin-orbit coupled (SOC) Fermi superfluid and the topological phase transition driven by a Zeeman field in the perspective of its ground-state wave-function. Without Zeeman coupling, FS shows new features characterizing the BCS-BEC crossover induced by SOC. In the presence of a Zeeman field, the topological phase transition is explored using both FS and the topological invariant. In particular, we obtain the analytical result of the topological invariant which explicitly demonstrates that the topological phase transition corresponds to a sudden change of the ground state wave-function. Consequently, FS diverges at the phase transition point with its critical behavior being: $χ\propto ln|h-h_{c}|$ . Based on this observation, we conclude that the topological phase transition can be detected by measuring the momentum distribution in cold atoms experiment.

description: Brane and warped Dvali-Gabadadze-Porrati inflationary universe models in the context of intermediate inflation are studied. In both models we consider that the energy density is a standard scalar field and we discuss the evolution of the universe during the slow-roll inflation. Also, we describe the conditions for these models. The corresponding Wilkinson Microwave Anisotropy Probe seven year data are utilized to fix some parameters in our models. Our results are compared to those found in General Relativity.
Factors in the affrication of the ejective alveolar fricative in Tigrinya
Creators: name: Moeng, Emily

Publisher: name: Zenodo
Year: 2019

description: Ejective fricatives are typologically rare sounds, attributable to the fact that they
 present an articulatory dilemma with contrasting demands for their fricative and
 ejective components. Several articulatory coping mechanisms have been observed
 across languages (Maddieson 1997; 1998). In the case of Tigrinya, Shosted & Rose
 (2011) find that the ejective alveolar fricative, /s’/, is affricated more often than not
 (/s’/ produced as [ts’]), proposing affrication to be another possible coping mech-
 anism. This study assesses two possible factors affecting the rate or degree of af-
 frication in Tigrinya: 1) the vowel environment surrounding /s’/ and 2) the lexical
 frequency of words containing /s’/. While we find no effect of lexical frequency,
 we find a significant effect of vowel context, with the lowest rate of affrication oc-
 curring following [i] and preceding [u]. We propose that this finding suggests that
 this environment, naturally aids the production of ejective fricatives due to vowel
 coarticulation, as the decreasing supralaryngeal volume over the duration of the
 fricative counteracts the loss of air due to frication.

Between tone and stress in Hamar
Creators: name: Petrollino, Sara
Publisher: name: Zenodo
Year: 2019

description: This paper provides a preliminary description of the word-prosodic system of
 Hamar, a South Omotic language spoken in South West Ethiopia. The prosodic
 system of Hamar shows properties of both stress accent and tone: accent is lexi-
 cally contrastive in nouns, but not in verbs, where it has a grammatical function.
 Post-lexical tonal oppositions arise when lexical accent and grammatical accent in-
 teract in both nouns and verbs. The prosodic behaviour of Hamar nouns and verbs
 is in line with the pattern proposed by Smith (2011), whereby nouns are higher than
 verbs in a hierarchy of phonological privilege.

description: In the advent of a pervasive presence of location sharing services researchers gained an unprecedented access to the direct records of human activity in space and time. This paper analyses geo-located Twitter messages in order to uncover global patterns of human mobility. Based on a dataset of almost a billion tweets recorded in 2012 we estimate volumes of international travelers in respect to their country of residence. We examine mobility profiles of different nations looking at the characteristics such as mobility rate, radius of gyration, diversity of destinations and a balance of the inflows and outflows. The temporal patterns disclose the universal seasons of increased international mobility and the peculiar national nature of overseen travels. Our analysis of the community structure of the Twitter mobility network, obtained with the iterative network partitioning, reveals spatially cohesive regions that follow the regional division of the world. Finally, we validate our result with the global tourism statistics and mobility models provided by other authors, and argue that Twitter is a viable source to understand and quantify global mobility patterns.

description: Rattus losea (Swinhoe, 1871). Proc. Zool. Soc. Lond., 1870:637 (1871). TYPE LOCALITY: Taiwan. DISTRIBUTION: Recorded from Taiwan, Pescadores Isis, S China (Fujian, Guangdong, Jiangxi, Hainan Isl), C Vietnam, S Laos, and Thailand (excluding peninsular Thailand); probably will also be found in Cambodia, N Laos and Vietnam, and parts of Burma borderingThailand (Musser and Newcomb, 1985). SYNONYMS: exiguus, sakeratensis. COMMENTS: Known morphological, geographical, and altitudinal boundaries; correctly and incorrectly assoicated scientific names; and geographic variation reviewed by Musser and Newcomb (1985). They also suggested that R. losea is morphologically and probably phylogenetically nearer R. osgoodi from the highlands of S Vietnam than any other species of Rattus, and speculated that R. losea is also phylogenetically linked to R. argentiventer .

description: Symbolic computation is the science of computing with symbolic objects (terms, formulae, programs, algebraic objects, geometrical objects, etc). Powerful symbolic algorithms have been developed during the past decades and have played an influential role in theorem proving, automated reasoning, software verification, model checking, rewriting, formalisation of mathematics, network security, Groebner bases, characteristic sets, etc. The international Symposium on "Symbolic Computation in Software Science" is the fourth in the SCSS workshop series. SCSS 2008 and 2010 took place at the Research Institute for Symbolic Computation (RISC), Hagenberg, Austria, and, SCSS 2009 took place in Gammarth, Tunisia. These symposium grew out of internal workshops that bring together researchers from: a) SCORE (Symbolic Computation Research Group) at the University of Tsukuba, Japan, b) Theorema Group at the Research Institute for Symbolic Computation, Johannes Kepler University Linz, Austria, c) SSFG (Software Science Foundation Group) at Kyoto University, Japan, and d) Sup'Com (Higher School of Communication of Tunis) at the University of Carthage, Tunisia.

description: This article discusses the use of modern information systems in the management of corporate enterprises. In particular, the basics of using information systems in the data mining of an enterprise based on artificial intelligence in the process of digitalization of the economyare set out on the example of the program1-C Enterprise 8.3. Currently, due to the fact that enterprises have a very large flow of information, the processof managing such corporate enterprises and making decisionsin them remains a very complex process.In the face of increasing uncertainty, business increasingly requires new, high-quality methods and tools that allow automatic data search based on previously incomprehensible algorithms and rules and identify unknown parameters. This will become the basis for the creation and implementation of new intelligent information systems based on artificial intelligence for enterprises. In this context,the article examinesthe role and importance of information systems based on artificial intelligence in deterministic, unstructured and weakly structured situations in the process of management and decision-making in corporate enterprises.

Publisher: name: Zenodo
Year: 2019

description: This paper details the nature of a set of extra-grammatical units that we call ver-
 bal gestures, found in several communities in the Central, Littoral, and Southern
 regions of Cameroon. We lay out the verbal gestures found in these communities,
 explain their usage and distribution within the context of the community and the
 language of the user, and situate the system of verbal gestures found in Cameroon
 in the larger linguistic context of Cameroonian multilingualism. Furthermore, we
 make preliminary proposals for a system of sounds that exists outside of that of
 the primary phonemic system, which interacts with the system of verbal gestures.

description: In this Rapid Communication, we describe how the presence of the third dimension may break the scale invariance in a two-dimensional Bose gas in a pancake-shaped trap. From the two-dimensional perspective, the possibility of a weak spilling of the atomic density beyond the ground-state of the confinement alters the two-dimensional chemical potential; in turn, this correction no longer supports scale invariance. We compare experimental data with numerical and analytic perturbative results and find a good agreement.
