description: The article is devoted to the construction of explicit one-step numerical methods with the strong orders of convergence 2.0, 2,5, and 3.0 for Ito stochastic differential equations with multidimensional non-commutative noise. We consider the numerical methods based on the unified Taylor-Ito and Taylor-Stratonovich expansions. For numerical modeling of iterated Ito and Stratonovich stochastic integrals of multiplicities 1 to 6 we appling the method of multiple Fourier-Legendre series converging in the sense of norm in Hilbert space $L_2([t, T]^k),$ $k=1,\ldots,6$. The article is addressed to engineers who use numerical modeling in stochastic control and for solving the non-linear filtering problem. The article can be interesting for the mathematicians who working in the field of high-order strong numerical methods for Ito stochastic differential equations.

description: According to the famous Kibble-Zurek mechanism (KZM), the universality of spontaneous defect generation in continuous phase transitions (CPTs) can be understood by the critical slowing down. In most CPTs of atomic Bose-Einstein condensates (BECs), the universality of spontaneous defect generations has been explained by the divergent relaxation time associated with the nontrivial gapless Bogoliubov excitations. However, for atomic BECs in synthetic gauge fields, their spontaneous superfluidity breakdown is resulted from the divergent correlation length associated with the zero Landau critical velocity. Here, by considering an atomic BEC ladder subjected to a synthetic magnetic field, we reveal that the spontaneous superfluidity breakdown obeys the KZM. The Kibble-Zurek scalings are derived from the Landau critical velocity which determines the correlation length. In further, the critical exponents are numerically extracted from the critical spatial-temporal dynamics of the bifurcation delay and the spontaneous vortex generation. Our study provides a general way to explore and understand the spontaneous superfluidity breakdown in CPTs from a single-well dispersion to a double-well one, such as, BECs in synthetic gauge fields, spin-orbit coupled BECs, and BECs in shaken optical lattices.

description: The GRAPES-3 muon telescope in Ooty, India had claimed detection of a 2 hour (h) high-energy ($\sim$20 GeV) burst of galactic cosmic-rays (GCRs) through a $>$50$σ$ surge in GeV muons, was caused by reconnection of the interplanetary magnetic field (IMF) in the magnetosphere that led to transient weakening of Earth's magnetic shield. This burst had occurred during a G4-class geomagnetic storm (storm) with a delay of $\frac{1}{2}$h relative to the coronal mass ejection (CME) of 22 June 2015 (Mohanty et al., 2016). However, recently a group interpreted the occurrence of the same burst in a subset of 31 neutron monitors (NMs) to have been the result of an anisotropy in interplanetary space (Evenson et al., 2017) in contrast to the claim in (Mohanty et al., 2016). A new analysis of the GRAPES-3 data with a fine 10.6$^{\circ}$ angular segmentation shows the speculation of interplanetary anisotropy to be incorrect, and offers a possible explanation of the NM observations. The observed 28 minutes (min) delay of the burst relative to the CME can be explained by the movement of the reconnection front from the bow shock to the surface of Earth at an average speed of 35 km/s, much lower than the CME speed of 700 km/s. This measurement may provide a more accurate estimate of the start of the storm.

Year: 2007

description: Water is vital for life. However, many people especially in developing countries have no access to adequate potable water services. In Ethiopia in both urban and rural areas many people do not get safe clean water. The need for clean potable water is high. Debre Zeit town has high water shortage problem. In this study the contingent valuation survey method is employed to analyze households' willingness to pay for the improved water services. In this study survey responses of 234 randomly selected sampled households from all kebeles Debre Zeit town were analyzed through descriptive and econometric analysis. The survey result shows that 99.57% of the survey respondents use pipe water. However, only 10.26% of the respondent satisfied with the status quo level. All survey respondents expressed their willingness to pay above the existing tariff level, though the amount of money they are willing to pay varies from individual to individual. That is, if the improved system is implemented the authorities can collect more money from water sale and at the same time the water need of the households would be satisfied. The survey result also shows that mean willingness to pay for one bucket or for 20 liter of improved water service is 10.2367 and 12.4786 cents according to the dichotomous choice and open-ended survey responses respectively. The total willingness to pay for one bucket or 20 liters of improved water services is 262,781.45 cents or Birr 2,627.82 per day or Birr 959,159.30 per year. Thej Results of both Probit and OLS econometric models show that age, household size, reliability dummy and the income variables influences households' willingness to pay for the improved water services in the Debre Zeit town. Therefore in designing the improved water supply system for the town policy makers need to take these socio- economic and demographic factors and water attributes into consideration.

description: This study was carried out to empirically examine the policy implication of military expenditure on economic growth in Ethiopia. Although national defense is an important function of government and security from external and internal threats that contributes to economic development, high military expenditures for defense or civil conflicts burden the economy and may impede growth. Thus, the paper was aimed at investigate the empirical economic implication of military expenditure on economic growth of Ethiopia and the paper also examined moderating effects of inflation and unemployment on the relationship between military expenditure and economic growth. The research employed secondary data for the period 1974/5-2017/18. In analyzing the long run and short run relationship between military expenditure and economic growth, Johansen's co-integration test, VECM, and Granger causality test was applied. Further, forecast Error Variance Decomposition was obtained using the cholesky decomposition of the VECM and used the generalized impulse response function. The study found that military expenditure affect economic growth negatively. The finding showed that there was a unidirectional causality running from economic growth to military expenditure in the long run. From the empirical finding, impulse response function suggested that military expenditure negatively impacts economic growth and Variance Decomposition also revealed that military expenditure has no important impact on future growth rate of output in Ethiopia. The empirical finding also found out that inflation and unemployment have significant moderating effects on the relationship between military expenditure and economic growth in the long run. Finally, this study recommends policy makers to consider the effects of military expenditure and spend more resources on productivity, which is growth enhancing, reducing unemployment, stabilizing inflation as well as foreign exchange market.

description: The goal of this article is to give an explicit classification of the possible $p$-adic Galois representations that are attached to elliptic curves $E$ with CM defined over $\mathbb{Q}(j(E))$. More precisely, let $K$ be an imaginary quadratic field, and let $\mathcal{O}_{K,f}$ be an order in $K$ of conductor $f\geq 1$. Let $E$ be an elliptic curve with CM by $\mathcal{O}_{K,f}$, such that $E$ is defined by a model over $\mathbb{Q}(j(E))$. Let $p\geq 2$ be a prime, let $G_{\mathbb{Q}(j(E))}$ be the absolute Galois group of $\mathbb{Q}(j(E))$, and let $ρ_{E,p^\infty}\colon G_{\mathbb{Q}(j(E))}\to \operatorname{GL}(2,\mathbb{Z}_p)$ be the Galois representation associated to the Galois action on the Tate module $T_p(E)$. The goal is then to describe, explicitly, the groups of $\operatorname{GL}(2,\mathbb{Z}_p)$ that can occur as images of $ρ_{E,p^\infty}$, up to conjugation, for an arbitrary order $\mathcal{O}_{K,f}$.

description: Particle acceleration induced by fast magnetic reconnection may help to solve current puzzles related to the interpretation of the very high energy (VHE) and neutrino missions from AGNs and compact sources in general. Our general relativistic-MHD simulations of accretion disk-corona systems reveal the growth of turbulence driven by MHD instabilities that lead to the development of fast magnetic reconnection in the corona. In addition, our simulations of relativistic MHD jets reveal the formation of several sites of fast reconnection induced by current-driven kink turbulence. The injection of thousands of test particles in these regions cause acceleration up to energies of several PeVs, thus demonstrating the ability of this process to accelerate particles and produce VHE and neutrino emission, specially in blazars. Finally, we discuss how reconnection can also explain the observed VHE luminosity-black hole mass correlation, involving hundreds of non-blazar sources like Perseus A, and black hole binaries.

description: Heavier resonances are continually being added to the hadronic spectrum from the Particle Data Group that follow an exponentially increasing mass spectrum. However, it has been suggested that even further states predicted from Quark Models are needed in the hadronic spectrum in order to improve the agreement between the hadron resonance gas model predictions and lattice QCD data. We find that the inclusion of such states with extrapolated branching ratios slightly decreases the freezeout temperature. To eliminate ambiguities, we introduce a first principle method to extract the freeze-out temperature for charged kaons from experimental data, which yields a lower bound of $T_{\text{fo}} \gtrsim $145 MeV for the highest collision energy at RHIC.

Explaining Ethiopia's Foreign Trade Potential: A Dynamic Gravity Approach
Creators: name: Gebrehiwot, Gebreyessus
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Towards improvement of Ethiopia's poor performance in the global trading system, the main objective of this paper is to estimate trade potential of the country with major trade partners around the world. The gravity model of trade has been duly employed for the purpose. For the sake of plausible results, recent innovations of the gravity model are incorporated as well. Specifically, a dynamic gravity approach based on a panel dataset of sample countries was estimated by System GMM estimators to first analyze the pattern of (basic vs export) trade flows. The coefficients obtained are then used to predict the basic trade and export trade potentials for Ethiopia. As a result, we found that the dynamic gravity model fits the data well, indicating the presence of hysteresis in trade. Besides, the traditional gravity variables are all significant with anticipated signs. The last major finding of the study is that considerable part of the country's potential trade has remained unrealized. The magnitude of trade potential was found the highest with Asian, European and then African countries as a continent. The study recommends that export diversification which advances the narrow export dependency, improvement of infrastructure which reduces transaction costs, and bilateral trade negotiations stepping up the current status of the external sector are the necessary steps to exploit Ethiopia's untapped trade potential.

description: A number of theories of gravity have been proposed as proxies for dark matter in the regime of galaxies and cosmology. The recent observations of gravitational waves (GW170817) from the merger of two neutron stars, followed by an electromagnetic counterpart (GW170817a) have placed stringent constraints on the difference of the speed of gravity to the speed of light, severely restricting the phenomenological viability of such theories. We revisit the impact of these observations on the Tensor-Vector-Scalar (TeVeS) paradigm of relativistic Modified Newtonian Dynamics (MOND) and demonstrate the existence of a previously unknown class of this paradigm where the speed of gravity always equals the speed of light. We show that this holds without altering the usual (bimetric) MOND phenomenology in galaxies.

The ruthenium carbamate complex derived from 3-trimethoxysilyl-1-

propyl amine and carbon dioxide was found to be a novel catalyst for

the oxidative cyanation of aromatic and cyclic tertiary amines to

corresponding a-amino nitriles in high to excellent yields by using

hydrogen peroxide and molecular oxygen as enviro-economic

oxidants. The developed protocol suggested an efficient alternative

for recycling carbon dioxide.

description: Veit Elser proposed a random graph model for percolation in which physical dimension appears as a parameter. Studying this model combinatorially leads naturally to the consideration of numerical graph invariants which we call \emph{Elser numbers} $\mathsf{els}_k(G)$, where $G$ is a connected graph and $k$ a nonnegative integer. Elser had proven that $\mathsf{els}_1(G)=0$ for all $G$. By interpreting the Elser numbers as Euler characteristics of appropriate simplicial complexes called \emph{nucleus complexes}, we prove that for all graphs $G$, they are nonpositive when $k=0$ and nonnegative for $k\geq2$. The last result confirms a conjecture of Elser. Furthermore, we give necessary and sufficient conditions, in terms of the 2-connected structure of~$G$, for the nonvanishing of the Elser numbers.
description: Corrected two errors in published version: (i) Conjecture 9.1 should read $k=|E(G)|-|V(G)|+1$ rather than $k=|E(G)|-|V(G)|-1$, and (ii) Theorems 1.2 and 7.5 should read "has no cut-vertex" rather than "is 2-connected" (so as to include $K_2$)

description: We introduce a class of modules over Kac-Moody superalgebras; we call these modules snowflake. These modules are characterized by invariance property of their characters with respect to a certain subgroup of the Weyl group. Examples of snowflake modules appear as admissible modules in representation theory of affine vertex algebras and in classification of bounded weight modules. Using these modules we prove Arakawa's Theorem for the Lie superalgebra osp(1|2n).

description: We performed Se and F-NMR measurements on single crystals of (TMTSF)2FSO3 to characterize the electronic structures of different phases in the Temperature-Pressure phase diagram, determined by precise transport measurements [Jo et al., Phys. Rev. B67, 014516 (2003)]. We claim that such varieties of electronic states in the refined phase diagram are caused by strong couplings of the conduction electrons with FSO3 anions, especially with the permanent electric dipoles on the anions. We suggest that as temperature decreases, the FSO3 anions form orientational ordering through two steps; first only the tetrahedrons form an orientational order leaving the orientations of the electronic dipoles in random (transition I); then the dipoles form a perfect orientational order at a lower temperature (transition II). In the intermediate temperature range between transitions I and II, we found an appreciable enhancement of homogeneous and inhomogeneous widths of 77Se-NMR spectrum. From the analysis of the angular dependence of the linewidth, we attributed these anomalies to the intramolecular charge disproportionation or imbalance and its slow dynamics caused by the coupling with the permanent electric dipole of anion. Results of 19F-NMR relaxation and lineshape measurements support this picture very well. Electronic structures at higher pressures up to 1.25 GPa are discussed on the basis of the results of the 77Se and 19F-NMR measurements.

Octahedralhexacyano rheniumK4[Re6S8(CN)6] cluster complexes were graftedontophotoactiveCu(OH)2

cluster modified TiO2 {Cu(OH)2/TiO2} support. The rhenium and copper cluster modified TiO2 photocatalyst combines the advantages of heterogeneous catalyst (facile recovery, recycling ability of the catalyst)

with the reactivity, selectivity of the soluble molecular catalyst. The synthesized heterogeneous catalyst was found to be highly efficient photoredox catalyst for the reduction of CO2 under visible light

irradiation. Methanol was found to be the major liquid product with the formation of hydrogen as a by

product as determined with GC-FID and GC-TCD, respectively. The methanol yield after 24 h irradiation

was found to be 149 mol/0.1 g cat. for Re-cluster@Cu(OH)2/TiO2 photocatalyst that is much higher than

35 mol/0.1 g cat. for Cu(OH)2/TiO2 and 75 mol/0.1 g cat. for equimolar rhenium cluster in the presence

of triethanolamine (TEOA) as a sacrificial donor. The quantum yields (MeOH) of Re-cluster@Cu(OH)2/TiO2

and Cu(OH)2/TiO2 were found to be 0.018 and 0.004 mol einstein−1, respectively. These values are much

higher than those reported for other heterogeneous catalysts for six electron transfer reaction.

description: This paper proves explicit bilipschitz bounds on the change in metric between the thick part of a cusped hyperbolic 3-manifold N and the thick part of any of its long Dehn fillings. Given a bilipschitz constant J > 1 and a thickness constant epsilon > 0, we quantify how long a Dehn filling suffices to guarantee a J-bilipschitz map on epsilon-thick parts. A similar theorem without quantitative control was previously proved by Brock and Bromberg, applying Hodgson and Kerckhoff's theory of cone deformations. We achieve quantitative control by bounding the analytic quantities that control the infinitesimal change in metric during the cone deformation. Our quantitative results have two immediate applications. First, we relate the Margulis number of N to the Margulis numbers of its Dehn fillings. In particular, we give a lower bound on the systole of any closed 3-manifold M whose Margulis number is less than 0.29. Combined with Shalen's upper bound on the volume of such a manifold, this gives a procedure to compute the finite list of 3-manifolds whose Margulis numbers are below 0.29. Our second application is to the cosmetic surgery conjecture. Given the systole of a one-cusped hyperbolic manifold N, we produce an explicit upper bound on the length of a slope involved in a cosmetic surgery on N. This reduces the cosmetic surgery conjecture on N to an explicit finite search.

description: We present a mid-IR interferometric survey of the circumstellar environment of a specific class of post-Asymptotic Giant Branch (post-AGB) binaries. For this class the presence of a compact dusty disk has been postulated on the basis of various spatially unresolved measurements. Our interferometric survey was performed with the MIDI instrument on the VLTI. In total 19 different systems were observed using variable baseline configurations. Combining all the visibilities at a single wavelength at 10.7 micron, we fitted two parametric models to the data: a uniform disk (UD) and a ring model mimicking a temperature gradient. We compared our observables of the whole sample, with synthetic data computed from a grid of radiative transfer models of passively irradiated disks in hydrostatic equilibrium. These models are computed with a Monte Carlo code that has been widely applied to describe the structure of protoplanetary disks around young stellar objects (YSO). The spatially resolved observations show that the majority of our targets cluster closely together in the distance-independent size-colour diagram, and have extremely compact N-band emission regions. The typical uniform disk diameter of the N-band emission region is about 40 mass which corresponds to a typical brightness temperature of 400-600~K. The resolved objects display very similar characteristics in the interferometric observables and in the spectral energy distributions. Therefore, the physical properties of the disks around our targets must be similar. The grid of protoplanetary disk models covers very well the observed objects. Much like for young stars, the spatially resolved N-band emission region is determined by the hot inner rim of the disk. Continued comparisons between post-AGB and protoplanetary disks will help to understand grain growth and disk evolution processes,

A relative heating coefficient and a corresponding optimal near field excitation are defined taking the skin effect of the surrounding medium into account. For small particle suspensions the optimal excitation is an electric dipole field for which explicit asymptotic expressions are readily obtained. It is then proven that the optimal permittivity function yielding a maximal absorption inside the spherical suspension is a conjugate match with respect to the surrounding lossy material. For a surrounding medium consisting of a weak electrolyte solution the optimal conjugate match can then readily be realized at a single frequency, e.g., by tuning the parameters of a Drude model corresponding to the electrophoretic particle acceleration mechanism. As such, the conjugate match can also be regarded to yield an optimal plasmonic resonance. Finally, a convex optimization approach is used to investigate the realizability of a passive material to approximate the desired conjugate match over a finite bandwidth. The relation of the proposed approach to general Mie theory as well as to the approximation of metamaterials are discussed. Numerical examples are included to illustrate the ultimate potential of heating in a realistic scenario in the microwave regime.

Impact of public educational spending on the Schooling outcome (The case of Ethiopia)
Creators: name: Asres, Wubishet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: This study examines the effect of government educational spending on schooling outcome in Ethiopia using the econometric methods of Ordinary least square. The study attempts to measure the impacts of public spending on educational sector using annual data set on public educational expenditure, adult literacy rate, and macroeconomic uncertainty proxied by consumer price index for the period 1980/81-2011/12.All the variables under consideration are stationary at their respective first difference of their growth rate. The results indicate that schooling outcome which is proxied by adult literacy rate positively related with all the identified explanatory variables except the consumer price index. The study found that public educational spending impacts positively and strongly schooling outcome. The policy implication of this study is that, current government should continue its monetary and fiscal measures so as to contain the growth of inflation since in the long run it have a negative effect on educational outcome.

description: PurposeThis perspective article responds to the emergence of artificial intelligence (AI) as a significant opportunity for growth among family businesses, highlighting the need for future research to attain a clear picture of the next generation of family business successors.Design/methodology/approachThis is a literature review of current technology adoption within family businesses. The authors offer some research insight to spur critical thinking and discourse around the impact of AI on family business successors.FindingsFamily businesses are initially skeptical of AI technology. However, its use and adoption are crucial for the survival of the family business. To leverage this technology, the authors need to investigate the role of the family business successors as “Gen AI.”Originality/valueIt is challenging but necessary to develop policies and educational support for successors to ensure the survival of family businesses worldwide. The authors propose four key areas of future research.
Objects in Bloom
Creators: name: Hegglund, Jon
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: Drawing upon Franco Moretti's reading of the early chapters of Ulysses as "stream-of-unconsciousness" narration, along with recent insights in object-oriented ontology and thing theory, my essay examines the ways in which the characters of Stephen Dedalus and Leopold Bloom are created through contrasting methods in the first six chapters of Joyce's novel. Where many critics would point to the animation of objects in "Circe" or the detached, catechistic descriptions of "Ithaca" to discuss the role of nonhuman things in the novel, I look instead to the more "conventionally" modernist chapters, particularly the triad that introduces Leopold Bloom: "Calypso," "Lotos-Eaters," and "Hades." In contrast to a style that organizes narration around Stephen Dedalus' sense perception in the first three chapters, the chapters that introduce Bloom place him, both narratively and syntactically, among a world of nonhuman objects and entities. Through a focus both on Bloom's immersion within objects, and indeed his own object-nature, Joyce advances a new model of character—one that is not an essence but instead a contingent material aggregation of things that must be constantly made anew.

ExPaNDS
European Photon and Neutron facilities

description: This ExPaNDS project deliverable describes a FAIR self-assessment undertaken by the ten ExPaNDS partner Photon and Neutron Research Infrastructures (PaN RIs) over the three-month period July – September 2022. After reviewing selected examples of existing FAIR evaluation frameworks designed to enable assessment at different levels (dataset,
 repository, and organisation), the report describes the evaluation approach adopted for the ExPaNDS FAIR self-assessment. As no existing framework met our specific need to focus on FAIR workflows and processes in PaN RIs, it was necessary to select, combine, and adapt existing frameworks. Supported by four underlying guiding principles, our approach drew heavily on the FAIR Principles, the RDA FAIR Data Maturity Model, and FAIRsFAIR’s CoreTrustSeal+FAIRenabling framework. Post-evaluation feedback from ExPaNDS partners indicated that they found the FAIR self-assessment a useful and valuable exercise for understanding current levels of FAIRness at their facilities and for articulating what implementations they have in progress or planned to support FAIR in future. A key output of the ExPaNDS FAIR evaluation is the collected self-assessment reports from the ten partner facilities. These reports are published openly and in full as part of the deliverable. In addition, the self-assessments are supplemented with some high-level observations on the state of the FAIR journey across the ExPaNDS facilities.

description: It is demonstrated that the electric dipole layer due to the overlapping of electron wavefunctions at metal/graphene contact results in negative Fermi-level pinning effect on the region of GaAs surface with low interface-trap density in metal/graphene/n-GaAs(001) junction. The graphene interlayer takes a role of diffusion barrier preventing the atomic intermixing at interface and preserving the low interface-trap density region. The negative Fermi-level pinning effect is supported by the Schottky barrier decreasing as metal work-function increasing. Our work shows that the graphene interlayer can invert the effective work-function of metal between $high$ and $low$, making it possible to form both Schottky and Ohmic-like contacts with identical (particularly $high$ work-function) metal electrodes on a semiconductor substrate possessing low surface-state density.

“'Sanft ist der Amsel Klage'”. Motivstrukturen bei Georg Trakl
Creators: name: Mengaldo, Elisabetta
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: "The essay examines the leitmotif-technique in the lyric poetry of the expressionist Austrian poet Georg Trakl (1887-1914). This term, which is common in musicology (for example to describe Wagner’s usual technique) and in literary studies (to delineate both narrative techniques and techniques of psychological characterisation, such as in Tolstoj’s and Thomas Mann’s texts), is here applied to Trakl’s poetry to describe images which feature recursivity, strongly connotative meaning and semantic open-endedness. In his poetry the leitmotif-technique appears to contribute to the formation of a private language, the opacity of which descends not so much from a programmatic intransitivity of the poetical language (as typified by Mallarmé), but rather from the need for a broken, dismembered, non-transparent communication. This linguistic obscurity develops as an existential feature before turning into aesthetic intention and poetic programme. Such construction of intratextual, ‘private’ semantic networks through leitmotifs is part of a progressive reduction of the semantic range and increasing ambiguity of the syntactic links, especially in Trakl’s late poetry."
Dall’orlo estremo di un’età sepolta: il “Valéry” di Walter Benjamin
Creators: name: Dogà, Ulisse
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: The article aims to analyze the presence of the French poet and writer Paul Valéry in the work of German philosopher Walter Benjamin. For many reasons - that will be investigated in detail - no interpreter seems to be more akin to Valéry than Walter Benjamin. Benjamin payed particular attention to Valéry: he followed his development, admired his greatness and reserved him special praise, that of having acquired the authority of a classic author. The article aims to show that Valéry remains for Benjamin intrinsically linked to the heroic period of the European bourgeoisie and that he is one of the most noble examples of what Benjamin calls "the old European humanism", of which Benjamin himself is one of the greatest protagonists, but also a disillusioned interpreter and relentless critic. The interpreter Benjamin recognized in Valéry was undoubtedly an "allied", as he found in his vision of the world a poetic image full of wit and melancholy. This image was also Benjamin's own, and he remained paradoxically faithful to it even in times of more fervent political and revolutionary passion. These are the principal points from which the article will start to rebuild and rethink the elective affinity between the French poet and the great German critic.
Temporal Correlation of Interference in Bounded Mobile Ad Hoc Networks with Blockage

description: In mobile wireless networks with blockage, different users, and/or a single user at different time slots, may be blocked by some common obstacles. Therefore the temporal correlation of interference does not depend only on the user displacement law but also on the spatial correlation introduced by the obstacles. In this letter, we show that in mobile networks with a high density of users, blockage increases the temporal correlation of interference, while in sparse networks blockage has the opposite effect.

description: We further the classification of rational surface singularities. Suppose $(S, \mathfrak{n}, \mathcal{k})$ is a strictly Henselian regular local ring of mixed characteristic $(0, p > 5)$. We classify functions $f$ for which $S/(f)$ has an isolated rational singularity at the maximal ideal $\mathfrak{n}$. The classification of such functions are used to show that if $(R, \mathfrak{m}, \mathcal{k})$ is an excellent, strictly Henselian, Gorenstein rational singularity of dimension $2$ and mixed characteristic $(0, p > 5)$, then there exists a split finite cover of $\mbox{Spec}(R)$ by a regular scheme. We give an application of our result to the study of $2$-dimensional BCM-regular singularities in mixed characteristic.

Vocis Imago. Zur archäologischen Dichtung Durs Grünbeins
Creators: name: Kocziscky, Eva
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: The article investigates Durs Grünbein’s love for ruins. This passion for archaeology is not only reflected in Grünbein’s poetic imagination but also in his poetic and aesthetic agenda, with its recourse to the great classics of German literature. On the whole, it can be stated that archeology itself and the the archaeological object paradoxically acquire their materiality and sensory presence through the poetic activity, whereby it is the poetic word itself which is excavated through language, or retrieved among the waste and the débris of our European culture.

The dual space used in analysis of the semi-geostrophic system with constant $f$ does not exist for the variable Coriolis parameter case, and we develop a time-stepping procedure to overcome this difficulty.
