description: A simulation based method for the numerical solution of PDE with random coefficients is presented. By the Feynman-Kac formula, the solution can be represented as conditional expectation of a functional of a corresponding stochastic differential equation driven by independent noise. A time discretization of the SDE for a set of points in the domain and a subsequent Monte Carlo regression lead to an approximation of the global solution of the random PDE. We provide an initial error and complexity analysis of the proposed method along with numerical examples illustrating its behaviour.

description: The assumption of the chronostratigraphic significance of seismic reflections serves as a fundamental premise in interpreting stratigraphy from seismic images. This hypothesis proposed in 1977 was initially applied to delineate depositional sequences as the basic interpretive unit, and then to reconstruct Wheeler Diagram and regional sea level curves. After a further comparison against with global eustatic events, these regional curves can further facilitate predicting the age, distribution, and facies of depositional sequence before drilling in a seismic-covered area during petroleum exploration. With a boom in reservoir-level seismic applications, for obtaining significant high frequency sequence (HFS) surfaces as the bounding surfaces in static reservoir model construction, this fundamental assumption was inevitably extended to characterize HFS and even high-frequency cycles (HFC) during seismic reservoir characterization. For an ultimate improvement in constructing reservoir-bounding surfaces, the author targeted at evaluating the validity of this fundamental assumption as applied to high-order seismic stratigraphy. The author conducted the entire project via the forward seismic modeling upon geologic models with known chronostratigraphic relationship. Besides, these input models carefully honor the reservoir geology for meaningful discussions on (1) shallow marine siliciclastic reservoirs in Starfak Field, GoM, (2) shallow-water mixed carbonate/clastic Upper San Andres-Grayburg reservoirs in Permian Basin, and (3) shallow-water carbonate Abo shelf margin-Clear Fork platform in Permian Basin. This study has achieved three-fold contributions. On the aspect of realistic geocellular, property and seismic modeling at the reservoir scale, the author integrated high-resolution sequence stratigraphic framework, published 3D depositional model, intra-facies heterogeneity in 3D modeling to selectively apply advanced geostatistical methods to model hierarchical heterogeneity. Subsequently, the author proposed an evaluation scheme with a defined parameter ('time-correlation error/TCE') to assess HFS-scale reservoir-bounding surfaces. These assessments revealed an interactive influence from (1) stratal geometry, (2) lateral lithofacies variation, (3) lithofacies-sonic velocity relationship in pure- versus mixed-lithology successions, (4) intra-facies heterogeneity, and (5) seismic frequency. Finally, based on these forward modeling results, the author proposed a decision tree to determine valid interpretation strategy in seismic chronostratigraphic correlation in scenarios with geoscientists’ expert knowledge and recommended an attribute-driven volumetric picking scheme to improve published algorithms for scenarios without prior knowledge.

description: This paper presents a heavy-traffic analysis of the behavior of a single-server queue under an Earliest-Deadline-First (EDF) scheduling policy in which customers have deadlines and are served only until their deadlines elapse. The performance of the system is measured by the fraction of reneged work (the residual work lost due to elapsed deadlines) which is shown to be minimized by the EDF policy. The evolution of the lead time distribution of customers in queue is described by a measure-valued process. The heavy traffic limit of this (properly scaled) process is shown to be a deterministic function of the limit of the scaled workload process which, in turn, is identified to be a doubly reflected Brownian motion. This paper complements previous work by Doytchinov, Lehoczky and Shreve on the EDF discipline in which customers are served to completion even after their deadlines elapse. The fraction of reneged work in a heavily loaded system and the fraction of late work in the corresponding system without reneging are compared using explicit formulas based on the heavy traffic approximations. The formulas are validated by simulation results.

description: Rotational bands with (neutron h_11/2)^1 (proton h_11/2)^1 configurations are studied using a particle-rotor model in which a proton and a neutron quasiparticles interacting through a zero-range force are coupled with a triaxial rotor. It is shown for 124Cs that one can reproduce the signature dependence of energy and B(M1)/B(E2) ratio best when one takes into account gamma-deformations with irrotational-flow moment of inertia in addition to the proton-neutron interaction proposed by Semmes and Ragnarsson. Including both effects, a systematic calculation of signature splittings is performed for Cs, La isotopes and N=75 isotones to be compared with experiments. Discussions are also done on the deficiencies of the cranking model concerning its applicability to signature inversion phenomena in odd-odd nuclei.

description: A numerical method for the fully adaptive sampling and interpolation of PDE with random data is presented. It is based on the idea that the solution of the PDE with stochastic data can be represented as conditional expectation of a functional of a corresponding stochastic differential equation (SDE). The physical domain is decomposed subject to a non-uniform grid and a classical Euler scheme is employed to approximately solve the SDE at grid vertices. Interpolation with a conforming finite element basis is employed to reconstruct a global solution of the problem. An a posteriori error estimator is introduced which provides a measure of the different error contributions. This facilitates the formulation of an adaptive algorithm to control the overall error by either reducing the stochastic error by locally evaluating more samples, or the approximation error by locally refining the underlying mesh. Numerical examples illustrate the performance of the presented novel method.
Hamiltonian increasing paths in random edge orderings

description: Let f be an edge ordering of Kn: a bijection E(Kn) → {1, 2, . . . , n2}. For an edge e ∈ E(Kn), we call f(e) the label of e. An increasing path in Kn is a simple path (visiting each vertex at most once) such that the label on each edge is greater than the label on the previous edge. We let S(f) be the number of edges in the longest increasing path. Chvatal and Komlos raised the question of estimating m(n): the minimum value of S(f) over all orderings f of Kn. The best known bounds on m(n) are , due respectively to Graham and Kleitman, and to Calderbank, Chung, and Sturtevant. Although the problem is natural, it has seen essentially no progress for three decades. In this paper, we consider the average case, when the ordering is chosen uniformly at random. We discover the surprising result that in the random setting, S(f) often takes its maximum possible value of n − 1 (visiting all of the vertices with a Hamiltonian increasing path). We prove that this occurs with probability at least about 1/e. We also prove that with probability 1 − o(1), there is an increasing path of length at least 0.85n, suggesting that this Hamiltonian (or near-Hamiltonian) phenomenon may hold asymptotically almost surely.

description: Minor Pb-Zn occurrences on the flanks of the Llano Uplift in Central Texas have many geologic similarities to the world-class Mississippi Valley Type (MVT) deposits of Southeast Missouri. In both areas, metallic sulfides are hosted in dolomitized Cambrian carbonates, commonly in areas where local basement highs forced depositional pinch-outs of the basal sandstones. In Southeast Missouri, mineralization has been attributed to basinal fluid migration associated with late Paleozoic Ouachita deformation and appears to be spatially related to regional faults that may have served as fluid conduits. In Central Texas, there is also evidence that mineralization is associated with basinal fluids tied to Ouachita deformation and abundant regional faults serve as plausible fluid pathways. Moreover, Southeast Missouri and Central Texas are distinctly rich in Pb, an atypical characteristic for MVT deposits that are usually Zn dominant. These similarities suggest that an understanding of spatial associations between sites of known mineralization and regional geology, geochemistry, and geophysics in Southeast Missouri will be a useful guide in future exploration efforts in Central Texas. The weights-of-evidence approach is used to evaluate regional geology, geochemistry, and geophysical datasets and produce posterior probability maps for MVT deposits in Southeast Missouri. Host rock characteristics, stream sediment geochemistry, and proximity to basement highs are some of the most useful data for predicting these deposits. Model parameters derived from Southeast Missouri are applied to the Llano Uplift region of Central Texas. Although available data sets for Central Texas are less detailed than Southeast Missouri, the Central Texas models generally agree with areas known to contain MVT mineralization. A higher resolution basement structure map for Central Texas would be useful for more detailed analysis. Central Texas model results are compared with semi-quantitative geochemical data from insoluble residues from wells throughout the Llano region and indicate that the model may be useful in explaining the measured Pb concentrations in these wells. Several new permissive areas to the south and southwest of the Precambrian core of the Llano Uplift are identified that may warrant additional follow up investigation. This work illustrates the potential utility of mineral potential modeling to prioritize areas for exploration for undiscovered MVT mineralization in Central Texas.

description: The decline in soil productivity amidst efforts to increase crop yield in Sub Saharan Africa (SSA) has made it imperative to assess the current fertilization management approaches. This study was conducted in two agroecological zones (i.e., Guinea Savannah (GS) and Deciduous forest (DF)) of Ghana to evaluate how different fertilization schemes in the long term (>5 years) impacted the soil biochemical properties. Soil samples under four fertilization schemes (inorganic fertilizer only, low-to-medium organic residues only, inorganic fertilizers plus low-to-medium organic residues, and no fertilization) from 20 farmers’ field were sampled from March to April 2015. Soil biochemical quality indicators were determined using standard procedures. Overall, the average chemical and microbial biomass contents for most indicators were significantly higher in DF compared to GS. Relative to the reference sites, soil quality improvement were observed under inorganic fertilization in both agroecologies in contrast to significant soil deterioration (26.5%) under sole organic residue application in GS. Furthermore, the results showed that increased inorganic fertilization rate alone or combination with organic residues improved soil quality relative to the reference. The present results suggest the need to raise the current fertilizer application rates, especially in GS in order to enhance optimum soil productivity.

description: Many factors affect and perpetuate the underrepresentation of minorities and females in science, mathematics, and engineering (SME) programs of study and careers, but the ones with greatest impact exist within the nation's educational system. Many students are underserved and underprepared educationally through the public schools. Additionally, assessment practices established by institutions of higher education (IHEs) can be a barrier to access into SME programs and careers Attempts have been undertaken to refine the academic skills and knowledge of underrepresented groups (e.g., academic intervention programs for enhancement) in order to encourage participation in SME studies and careers. This investigation focused on: (1) the impact of an intervention program on the cognitive performance of its participants on an achievement-type instrument, and (2) comparing attitudes of PIPE (Precollege Intervention Program for Enrichment) participants and non-participant peers toward SME careers. Using selected items from the mathematics and science subsections of three norm-referenced achievement tests, a new instrument was developed to examine the cognitive effects of the intervention program on rising ninth grade, First-Year PIPE participants. Items from a normed questionnaire and additional researcher-generated statements were used to produce a 5-point Likert-type questionnaire to examine the interests and attitudes of the sample toward careers in SME. First-Year, first time PIPE participants, were selected from five schools in an urban area near the Mexican border. The sample used was a sample of convenience to whom the instruments identified previously were administered. Results of a t-test analysis on each of the sections of TEST A revealed that PIPE participants performed better than did non-participant academic peers. A t-test analysis was used on the unidimensional scale extracted from TEST B to detect a difference in attitude held or adopted by students toward careers in SME. This PIPE model, as implemented, has significant positive effects on the cognitive performance of its participants compared to their nonparticipant peers. There were no significant differences observed between groups on attitude toward SME careers, nor was there a difference detected according to self-reported English-Spanish bilinguality

description: We investigate the behavior of a $d$-$d$ transition in NiO using a new x-ray spectrometer with 0.025 eV resolution at 15816 eV, and via ab-initio ligand field theory calculations. The transition at ~1.7 eV energy transfer is measured at temperatures between 20 and 800 K, at a momentum transfer |$\bf{Q}$| = 6.52 Å$^{-1}$. Fine structure is clearly observed at 20 K. As temperature is increased, the excitation shifts to lower energy and broadens. We explain the energy shift as being related to thermal expansion and to magnetism. The broadening is well fit considering thermal fluctuations of the Ni-O bond length, with a scale factor found to be in reasonable agreement with calculation.

description: Massive stars with solar metallicity lose important amounts of rotational angular momentum through their winds. When a magnetic field is present at the surface of a star, efficient angular momentum losses can still be achieved even when the mass-loss rate is very modest, at lower metallicities, or for lower-initial-mass stars. In a close binary system, the effect of wind magnetic braking also interacts with the influence of tides, resulting in a complex evolution of rotation. We study the interactions between the process of wind magnetic braking and tides in close binary systems. We discuss the evolution of a 10 M$_\odot$ star in a close binary system with a 7 M$_\odot$ companion using the Geneva stellar evolution code. The initial orbital period is 1.2 days. The 10 M$_\odot$ star has a surface magnetic field of 1 kG. Various initial rotations are considered. We use two different approaches for the internal angular momentum transport. In one of them, angular momentum is transported by shear and meridional currents. In the other, a strong internal magnetic field imposes nearly perfect solid-body rotation. The evolution of the primary is computed until the first mass-transfer episode occurs. The cases of different values for the magnetic fields and for various orbital periods and mass ratios are briefly discussed. We show that, independently of the initial rotation rate of the primary and the efficiency of the internal angular momentum transport, the surface rotation of the primary will converge, in a time that is short with respect to the main-sequence lifetime, towards a slowly evolving velocity that is different from the synchronization velocity.

description: Madiza fabae Rondani, 1876
ORIGINAL DESCRIPTION: 1876a: 64.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Parma (Italy) because he referred to observations made by himself.
 TYPE MATERIAL: 3 ♀♀, syntypes (one missing right fore- and mid-legs; one glued to a cardboard) (MZUF: Box 38): Madiza Fall. Siphonella Mcqrt / ruficornis Mcqrt / 2051 / in caule Vicia fabae.
 CURRENT STATUS: Becker (1905), Nartshuk (1984b), Canzoneri et al. (1995), and O’Hara et al. (2011) did not list it;  incertae sedis in Chloropidae (this work).
 REMARKS: Rondani (1876a: 64) included enough characters in his original description to allow us to separate this nominal species from Madiza (Siphonella) ruficornis Macquart, 1835. The MZUF did not contain any specimen named Madiza fabae but, under the name Madiza ruficornis, there are three specimens labeled “ in caule Vicia fabae [in a Vicia fabae stem]”. In our opinion, these could be the syntypes for Madiza fabae. An additional female in the MZUF numbered “2051” and labeled “ M. ruficornis in tipica Vicia fabae ” is not included in the type series because its label is yellowish rather than the greenish color of Rondani’s original handwritten ones and is in a lower row in the Box: we treat it to be a subsequent addition. Rondani (1876a) included Madiza fabae in the family Chloropidae. Nowadays the genus Madiza Fallén, 1810 is included in the family Milichiidae (Evenhuis & Pape 2020). However, our study of the type allows us to confirm this nominal species belongs to the family Chloropidae, as confirmed by the biology of the species (stem-miners) and its label (Siphonella Macquart, 1835 belongs to Chloropidae).

The emergence of these properties from such man-made networks is explained as a consequence of the currently used principles for process design, which include heuristics as well as algorithmic techniques. We expect these results to be valid for chemical plants of different types and capacities.

description: Либерализация международной торговли во многих странах и регионах открывает много перспектив для их экономического роста, притока ино-странных инвестиций и технологий. Гипотеза о позитивном влиянии свободной международной торговли на благосостояние всех наций оста-валась на протяжении многих лет почти неоспоримой. Так на протяже-нии 1970-х и 1980-х гг. базовая модель сравнительных преимуществ, впервые предложенная Рикардо в 1817 г., рассматривалась как достаточ-ное обоснование необходимости поощрения свободной международной торговли. В периоды глобальных рецессий, когда мировая экономика переживала стагнацию, тренд развития теорий международной торговли находился в зоне отрицательной динамики. Однако новые эмпирические данные о взаимосвязи международ-ной торговли с благосостоянием нации, базировавшиеся на прежних представлениях о факторных детерминантах изменения вектора и струк-туры торговли, оказались недостаточными для понимания движущих сил ее отраслевой дифференциации и подтолкнули формирование новой тео-ретической базы теории торговли.

description: The relationship between radiogenic ⁴He in zircon, and its associated radiation damage to the crystal lattice, have been of scientific interest since the earliest attempts at geochronology, and remain an active topic of research today in the pursuit of understanding the timing of low-temperature geological processes. Recently, the complex interrelationships between ⁴He diffusion kinetics, time, temperature, and radiation damage were quantified into a complete model for the zircon (U-Th)/He (ZHe) thermochronometric system: the Zircon Radiation Damage Accumulation and Annealing Model (ZRDAAM). Many researchers have taken issue with the predictions of this model, however, particularly at moderate to high radiation doses (~3 × 10¹⁷ – 2 × 10¹⁹ α/g). In this submission, the relationship between radiation damage and ⁴He diffusion kinetics are examined in greater detail to identify sources of discrepancy between observations and model predictions. Using zircons from three geologically distinct localities, this work represents the largest study on the diffusion kinetics of ⁴He from zircon to date, including 26 cycled step-heating analyses. A new behavior is observed in diffusion kinetics behavior, termed ‘rollover’: a thermally activated decrease in diffusivities, interpreted as low-temeprature annealing. Comparing the results of modeled and observed ZHe dating and step-heating analyses, we find significant discrepancies with model predictions in agreement with previous research. The source of these discrepancies is identified as low-temperature annealing, a process distinct from epitaxial recrystallization, resulting in significant effects on diffusional behavior, and not accounted for in the ZRDAAM. Results reveal that the damage threshold beyond which model diffusivities increase is too high, likely as a result of extensive prior geological annealing of the high-damage Sri Lankan zircons used to calibrate the ZRDAAM. Furthermore, the use of a single alpha dose appears inappropriate for capturing the full complexity of the ZHe system. Lastly, these results strongly suggest that the diffusion of ⁴He from zircon proceeds in a manner similar to a homogeneous gas, in spite of the fact that natural ⁴He concentrations are often strongly heterogeneous. This work is a significant step forward in the improvement of ZHe thermochronology, and will yield to the recovery of more accurate and robust thermal histories.

description: High resolution N-body simulations of cold dark matter (CDM) models predict that galaxies and clusters have cuspy halos with excessive substructure. Observations reveal smooth halos with central density cores. One possible resolution of this conflict is that the dark matter is warm (WDM); this will suppress the power spectrum on small scales. The Lyman-alpha forest is a powerful probe of the linear power spectrum on these scales. We use collisionless N-body simulations to follow the evolution of structure in WDM models, and analyze artificial Lyman-alpha forest spectra extracted from them. By requiring that there is enough small-scale power in the linear power spectrum to reproduce the observed properties of the Lyman-alpha forest in quasar spectra, we derive a lower limit to the mass of the WDM particle of 750 eV. This limit is robust to reasonable uncertainties in our assumption about the temperature of the mean density gas (T0) at z=3. We argue that any model that suppresses the CDM linear theory power spectrum more severely than a 750 eV WDM particle cannot produce the Lyman-alpha forest.

title: Struktur und Funktion respiratorischer Cytochrom c-Sulfitreduktase-Systeme

description: Sulfit bzw. Hydrogensulfit ist ein wichtiges Zwischenprodukt des Schwefelkreislaufs, als reaktive Schwefelverbindung aber auch ein Toxin. Das Epsilonproteobakterium Wolinella succinogenes verwendet für die Sulfit-Atmung und -Detoxifizierung die Oktahäm-Cytochrom c-Sulfit-Reduktase MccA, welche im mcc-Gencluster kodiert ist. Stromaufwärts von mccA sind die Gene des hypothetischen Zweikomponentensystems mccR und S lokalisiert. Stromabwärts von mccA liegen Gene, deren Produkte an der putativen Elektronentransportkette vom Chinonpool zu MccA beteiligt sein dürften (mccC und D), solche für die Reifung von MccA (mccB, ccsA1 und mccL) und solche mit unbekannter Funktion (mccE und F). Für den Elektronentransport zwischen respiratorischen Komplexen verwendet W. succinogenes Menachinon (MK) und dessen Derivat 8 Methylmenachinon (8-MMK), wobei letzteres aufgrund des negativeren Redoxpotentials des 8 MMK/8 MMKH2-Paares für die Sulfitatmung thermodynamisch günstiger ist. In dieser Arbeit wurde durch Leseraster-Mutation der Leserahmen von mccR in der Mutante W. succinogenes mccR+ cat verlängert, was im Gegensatz zum Wildstamm die gleichzeitige Atmung von Sulfit und Fumarat erlaubte. Derivate von W. succinogenes mccR+ cat mit einzelnen nichtpolaren Gendeletionen zeigten, dass mccB, C und D für die Sulfitatmung essenziell waren, während Zellen ohne mccL oder 8 MMK Sulfit mit verringerter Aktivität reduzierten. Die simultane Deletion von mccE und F hatte dagegen keinen Einfluss auf die Sulfitatmung. Eine Streptag-markierte Variante von MccA wurde unter der Kontrolle des mcc-Promotors in W. succinogenes produziert und gereinigt. Dessen Varianten, bei welchen eines der beiden Cu(I)-bindenden Cysteine durch Alanin ausgetauscht wurde, zeigten zwar dieselben spektroskopische Eigenschaften wie Wildstamm-MccA, waren zur Sulfitreduktion aber nicht in der Lage und enthielten kein Cu(I). Wildstamm-MccA wurde durch hohe Nitritkonzentrationen gehemmt, wohingegen das Cu(I)-lose MccA_C399A twS keine Substratinhibierung zeigte. Das Eisen-Schwefel-Protein MccC wurde heterolog in Escherichia coli produziert. Da es nur einen Teil der erwarteten [4Fe4S]-Zentren enthielt, wurde es anschließend in vitro rekonstituiert. MccL wurde sowohl in W. succinogenes als auch in E. coli produziert, gereinigt und der Kupfergehalt bestimmt. Durch in vitro-Rekonstitution war das Protein zusätzlich mit Cu(I) beladbar. Schließlich wurden MccA-Homologe und mcc Gencluster in Beta-, Gamma- und Deltaproteobakterien identifiziert und die Diversität der mcc-Gencluster untersucht. Insgesamt wurden die Cytochrom c-Sulfitreduktasen im bisher nicht erreichtem Detail untersucht und die Aufgaben der beteiligten Komponenten beleuchtet.

description: Annotation of the recording Hayu 1972 Tape 2 side B, an elicitation of Hayu disyllabic nouns. The speaker, a woman of about 50, was prompted in Nepali to pronounce single Hayu words at least twice, in a (sometimes inappropriate) frame "mi ___ nomi" 'that is a ___'. (The prompts were not usually recorded.) The XML annotation is a provisional adaptation of the Lacito TEXT annotation. Each S element contains the responses to a prompt for a single word. It contains a transcription of the speakers response ("phono"), a lexical form ("ortho") identifying the word elicited, and a translation of the word. These last serve as rough indexing keys. If a response contains additional words of interest (i.e. not 'that', 'is', etc.), it is annotated again in a new S element for each such word. The transcription is mainly IPA-based exept that 'y' is used for jod (IPA [j]).

description: In this paper we generalize the well-known notions of affine arclength and affine hypersurface measure to submanifolds of any dimension $d$ in $\mathbb R^n$ , $1 \leq d \leq n-1$. We show that a canonical affine invariant measure exists and that, modulo sufficient regularity assumptions on the submanifold, the measure satisfies the affine curvature condition of D. Oberlin with an exponent which is best possible. The proof combines aspects of Geometric Invariant Theory, convex geometry, and frame theory. A significant new element of the proof is a generalization to higher dimensions of an earlier result of the author concerning inequalities of reverse Sobolev type for polynomials on arbitrary measurable subsets of the real line.

description: In this paper we provide a well-posedness theory for weak measure solutions of the Cauchy problem for a family of nonlocal interaction equations. These equations are continuum models for interacting particle systems with attractive/repulsive pairwise interaction potentials. The main phenomenon of interest is that, even with smooth initial data, the solutions can concentrate mass in finite time. We develop an existence theory that enables one to go beyond the blow-up time in classical norms and allows for solutions to form atomic parts of the measure in finite time. The weak measure solutions are shown to be unique and exist globally in time. Moreover, in the case of sufficiently attractive potentials, we show the finite-time total collapse of the solution onto a single point for compactly supported initial measures. Our approach is based on the theory of gradient flows in the space of probability measures endowed with the Wasserstein metric. In addition to classical tools, we exploit the stability of the flow with respect to the transportation distance to greatly simplify many problems by reducing them to questions about particle approximations.

description: Samples of the Ru1-xFexSr2GdCu2O8 system with x = 0, 0.025, 0.05, 0.075, 0.1 and 0.2, were prepared and their structural, superconducting and magnetic properties were studied. Rietveld refinement of the X-ray diffraction patterns show that the Fe substitution occurs in both Ru and Cu sites. An increase of Fe concentration produces no significant changes in the bond angle Ru-O(3)-Ru, which is a measure of the rotation of the RuO6 octahedra around the c-axis, and also in the bond angle Ru-O(1)-Cu, which is a measure of the canting of the RuO6 octahedra. On the other hand, the bond angle Cu-O(2)-Cu, which is a measure of the buckling of the CuO2 layer, has a slight tendency to decrease with the increase of the Fe content. We found thet both ferromagnetic and superconducting transition temperatures are reduced with the increase of Fe concentration. Analisys related to the decay of the superconducting and ferromagnetic states is presented.

description: The effective gravitational mass as well as the energy and momentum distributions of a radiating charged particle in Einstein's universe are evaluated. The Moller's energy-momentum complex is employed for this computation. The spacetime under study is a generalization of Bonnor and Vaidya spacetime in the sense that the metric is described in the cosmological background of Einstein's universe in lieu of the flat background. Several spacetimes are limiting cases of the one considered here. Particularly for the Reissner-Nordstrom black hole background, our results are exactly the same with those derived by Cohen and Gautreau using Whittaker's theorem and by Cohen and de Felice using Komar's mass. Furthermore, the power output for the spacetime under consideration is obtained.
