GENERALIZATIONS OF THE LSMR AND NSCG METHODS FOR SOLVING MATRIX EQUATIONS

In this paper, We present the generalizations of the LSMR and NSCG methods for solving matrix equations. First, based on the LSMR algorithm, the Bl-LSMR and Gl-LSMR algorithms are derived by minimizing the Frobenius norm of residual matrix of normal equation. In addition, by extending the idea of LSMR algorithm, we also present the LSMR-M algorithm for solving the general coupled matrix equations. Next, based on NSCG and NS-CGNR methods, we establish the iterative methods which are inner/outer iterations for solving the sylvester equation and matrix equation AXB = C. Convergence conditions of each method are studied in dept and by using the numerical experiments the efficiency of the methods versus some well-known iterative method are shown. We also show that the Hermitian splitting and quasi-Hermitian splitting can induce accurate, robust, and effective preconditioned Krylov subspace methods.

C 20xx Society for Industrial and Applied Mathematics Brownian Motion in Dire Straits *

The passage of Brownian motion through a bottleneck in a bounded domain is a rare event, and as the bottleneck radius shrinks to zero the mean time for such passage increases indefinitely. Its calculation reveals the effect of geometry and smoothness on the flux through the bottleneck. We find new behavior of the narrow escape time through bottlenecks in planar and spatial domains and on a surface. Some applications in cellular biology and neurobiology are discussed.

Peculiarities of Bone Regeneration in Cases of Bio-Oss® and Autological Bone Graft Use – Experimental Study

Background. Bone tissue regeneration remains one of the most important issues of maxillofacial surgery. Restoration of the native structure of bone after osteoplasty is directly related to the process of revascularization, because the growing of blood vessels into the graft is a precondition for transport of osteogenic cells, growth factors necessary for further osteogenesis. Objectives. To determine the peculiarities of bone tissue regeneration after osteoplasty with BioOss® and compare it with autological bone graft. Material and Methods. Experimental study was conducted on 60 white rats (males, aged 6–8 month, weight 270– –380 g). The area of dorsal surface of the shinbone was used for implantation. After opening access to the bone surface, one 2 mm-diameter defect was formed on each shinbone. One of those bone defects was filled with osteoplastic material and the opposite was healing under a blood clot. After that the wound in soft tissues was closed in layer by layer. The osteocalcin level in blood serum was determined by ELIsA employing N-MID Osteocalcin® ELIsA (IDs) test system(enzyme immunological test for the quantitative measurement of osteocalcin). The peculiarities of revascularization were studied by histologic method. Histologic specimen were stained using schmorl technique (thionine with phenol trinitrate) and natural hematoxylin-eosin. Results. Mean values of osteocalcin concentration after BioOss implantation ranged from 2 ± 0.06 ng/mL to 3.65 ± 0.09 ng/mL; after autological bone graft transplant – from 1.88 ± 0.09 ng/mL to 2.2 ± 0.09 ng/mL. In the case of Bio-Oss use, the most active revascularization processes and the highest level of osteocalcin were registered on day 60. In the case of autological bone graft use, the quantity of blood vessels increased steadily and equally during the whole period of the experiment. Conclusions. According to the obtained results, the use of autological bone graft and Bio-Oss osteoplastic material increases bone formation and revascularization activity and improves the bone structure unlike when healing took place under the blood clot (Dent. Med. Probl. 2014, 51, 4, 458–467).
Floral abundance and soil characteristics affect wild bee community structures and nesting dynamics in tallgrass prairies

Tallgrass prairies have been reduced to less than 5% of their former range, yet provide essential habitats for many native plants and animals such as pollinators. Land managers work to preserve the biodiversity within these tallgrass prairies by implementing management techniques such as burning, haying, and patch-burn-grazing (PBG). All treatments utilize burning, but haying removes aboveground biomass and PBG includes grazing by cattle. The impacts of these management practices on important ecological factors for bee species, such as floral community structure and nesting resources are examined in this study. Floral resources and bee communities are usually positively correlated within ecosystems due to their mutualistic interactions. The interactions between flowers and bees are important in maintaining the sustainability of many ecosystems including managed prairies. In Chapter 1, I investigate how management alters the abundance, richness, diversity, and composition of both plant and bee communities and whether there are differences in the interactions between bee species and the plants they forage on within 20 different prairie sites in Missouri. Analyses were conducted for the four treatments and by collapsing the treatments into two groups, grazed and ungrazed. I discovered that floral abundance in ungrazed sites is higher than on sites that support cattle. However, the bee communities that utilize prairie ecosystems do not change based on management techniques. This may be due to the resilience of the bee species that occur in Missouri compared to the species that occurred in Missouri before the landscape was fragmented. Species remaining in the highly disturbed prairie fragments may be less specialized and better adapted at persisting despite the difference in management. Despite there being no difference in bee communities in grazed and ungrazed patches, the interaction networks between bee species and their host plants are more complex in the prairies without cattle and more iii competitive in the prairies with cattle. Additionally, out of the 1769 bees included in my study, only two were honey bees. Therefore, I found no evidence that honey bees are displacing native bees in prairie ecosystems. Soil characteristics could also affect bee community structure and nesting rates on prairies because most bees nest underground for the majority of their lives. In Chapter 2, I investigate the soil characteristics within the four management treatments including temperature, moisture, pH, bulk density, composition, and bare ground ranks and compare the measurements to ground-nesting bee nesting rates. I used emergence tents to collect ground-nesting …
Control of Robotic Manipulators Using G.a. & A.n.n

This paper presents application of G.A. to find out the topology of different A.N. N. techniques for the control of Robot. The neural network is trained for the inverse kinematics by providing it with a random data set of the manipulator spread over its workspace. Neural Networks have been used due to the inherent limitations of the conventional techniques to solve the inverse kinematics problem. Using G.A. results for a 2 D.O. F. manipulator, a comparison of different A.N. N. techniques are also presented for the above problems. Introduction: The kinematics & dynamic relationships of a manipulator are highly non-linear.

EXTRA VERSION AND SEX DIFFERENCES IN READING PERFORMANCE IN EIGHT‐YEAR‐OLD CHILDREN

Summary. 48 children aged 7–8 years were given the Junior Eysenck Personality Inventory and three reading tests which differed in the amount of context provided and the task required: (a) the Burt Graded Reading Test (words without context), (b) the NFER Primary Reading Test 2 (PRT2) (sentence completion), and (c) material taken from the Neale Analysis of Reading Ability (passage comprehension) of two levels of difficulty. Similar significant interactions were found between sex and extraversion in their effect on performance for all three types of test such that for boys, extraverts did best, while for girls introverts were superior. Further, significant interactions were observed for the passage comprehension between passage difficulty and mode of reading (aloud/silently), in that reading aloud was superior for high difficulty and reading silently for low, and for passage difficulty and extraversion, in that ambiverts performed least well with the difficult material.
Four Years of Continuous Surface Aerosol Measurements from the Department of Energy's Atmospheric Radiation Measurement Program Southern Great Plains Cloud and Radiation Testbed Site

explained by the indirect aerosol cloud effect. The use of a parcel model to determine the cloud droplet number concentration enables us to separate the effects of the cloud LWP and cloud droplet number concentration on the cloud optical depth. An examination of the TOA shortwave flux from the radiative transfer model applied to the two sites does not directly confirm the indirect effect, because the observed surface albedos at the NSA site for our cases (0.6 ^ 0.28) are significantly larger than those from the SGP site (0.2 ^ 0.02). However, the model can be used to estimate the outgoing flux difference if the clouds from the NSA site had the same average surface albedo and average zenith angle as those from the SGP site (see Fig. 3). This analysis indicates that these sites provide important evidence corroborating the effect of aerosols on cloud optical properties and on shortwave fluxes at both the surface and the TOA. Moreover, the analysis indicates that a parameteriza-tion of the effects of aerosols on clouds on the basis of an adiabatic parcel model and average aerosol size distributions such as those used in current general circulation models 18,22,23 provides a good estimate of cloud optical properties determined over a broad range of aerosol concentrations.

The great transition : Implication from environmental policy on the quality-quantity trade-o ff on children

We develop an overlapping-generations model with human capital accumulation and endogenous fertility containing a pollution externality. In such a framework, we study the effects of an environmental policy change on individuals’ quality-quantity trade-off on children. In a Malthusian poverty trap, we show that a more stringent policy induces a reduction of the fertility rate. In a state of perpetual development, however, not only is this policy likely to have a positive effect on fertility, but we also obtain that environmental quality, growth, and welfare are compatible goals. Moreover, we show that an abatement pollution policy can be used as an instrument for initiating a country’s “great transition” from a state of poverty to a state of
Estratégia Evolucionária e Algoritmo Genético para Otimização Dinâmica de Parâmetros de EFuNNs

Redes neurais difusas com estrutura adaptativa (EFuNNs) são normalmente utilizadas para modelar processos dinâmicos, que se desenvolvem e se modificam de maneira contı́nua no tempo. Este tipo de rede neural possui alguns parâmetros fixos, que não se alteram durante o aprendizado. O melhor conjunto de parâmetros fixos normalmente depende dos dados apresentados, de forma que se os dados mudam, o melhor conjunto de parâmetros também muda. Este artigo apresenta duas abordagens que utilizam computação evolucionária para realizar a otimização on-line desses parâmetros. Uma delas utiliza um algoritmo genético e a outra utiliza uma estratégia evolucionária. As redes neurais foram utilizadas para previsão de séries temporais caóticas Mackey-Glass. Um estudo comparativo entre estas abordagens e algumas de suas variações é apresentado.

A common problem facing many users today is to extract and combine information from multiple, heterogeneous sources and to derive information of a new quality or abstraction level. Though essential parts of this information fusion process can be supported by techniques developed in the eld of federated databases, new approaches for managing consistency, uncertainty or quality of data and enabling eÆcient analysis of distributed, heterogenous sources are still required. This paper presents a brief survey of requirements and applications of information fusion from the database view, discusses the usage of federated database technologies in fusion systems and points out possible research directions.
Wolfgang von Ohnesorge

This manuscript got started when one of us (G.H.M.) presented a lecture at the Institute of Mathematics and its Applications at the University of Minnesota. The presentation included a photograph of Rayleigh and made frequent mention of the Ohnesorge number. When the other of us (M.R.) enquired about a picture of Ohnesorge, we found out that none were readily available on the web. Indeed, little about Ohnesorge is available from easily accessible public sources. A good part of the reason is certainly that, unlike other “numbermen” of fluid mechanics, Ohnesorge did not pursue an academic career. The purpose of this article is to fill the gap and shed some light on the life of Wolfgang von Ohnesorge. We shall discuss the highlights of his biography, his scientific contributions, their physical significance, and their impact today.
Large deviations for the degree structure in preferential attachment schemes

Preferential attachment schemes, where the selection mechanism is linear and possibly time-dependent, are considered, and an infinite-dimensional large deviation principle for the sample path evolution of the empirical degree distribution is found by Dupuis-Ellis-type methods. Interestingly, the rate function, which can be evaluated, contains a term which accounts for the cost of assigning a fraction of the total degree to an "infinite" degree component, that is, when an atypical "condensation" effect occurs with respect to the degree structure. As a consequence of the large deviation results, a sample path a.s. law of large numbers for the degree distribution is deduced in terms of a coupled system of ODEs from which power law bounds for the limiting degree distribution are given. However, by analyzing the rate function, one can see that the process can deviate to a variety of atypical nonpower law distributions with finite cost, including distributions typically associated with sub and superlinear selection models.
Unifying discrete and continuous Weyl-Titchmarsh theory via a class of linear Hamiltonian systems on Sturmian time scales

In this study, we are concerned with introducing Weyl-Titchmarsh theory for a class of dynamic linear Hamiltonian nabla systems over a half-line on Sturmian time scales. After developing fundamental properties of solutions and regular spectral problems, we introduce the corresponding maximal and minimal operators for the system. Matrix disks are constructed and proved to be nested and converge to a limiting set. Some precise relationships among the rank of the matrix radius of the limiting set, the number of linearly independent square summable solutions, and the defect indices of the minimal operator are established. Using the above results, a classification of singular dynamic linear Hamiltonian nabla systems is given in terms of the defect indices of the minimal operator, and several equivalent conditions on the cases of limit point and limit circle are obtained, respectively. These results unify and extend certain classic and recent results on the subject in the continuous and discrete cases, respectively, to Sturmian time scales.
Every Little Helps

The National Health Service (NHS) is facing an unprecedented financial burden. We have to save up to £22 billion over next five years. Some savings can be obtained by efficient working but the majority can be achieved by working ‘smartly’ and reducing wastage. Our advances in medicine are putting greater pressure on our finances and therefore we need to be more focussed to ensure that the precious resources of the NHS are utilised as effectively as possible.

Recursive system identification by stochastic approximation

The convergence theorems for the stochastic approximation (SA) algorithm with expanding truncations are first presented, which the system identification methods discussed in the paper are essentially based on. Then, the recursive identification algorithms are respectively defined for the multivariate errors-in-variables systems, Hammerstein systems, and Wiener systems. All estimates given in the paper are strongly consistent.

Localisation et dynamique du front de la brise de mer au Maghreb oriental

Ce travail montre l’interet d’utiliser des images Meteosat Second Generation-Rapid Scan Service (MSG-RSS) prises dans le visible a une resolution temporelle tres fine (5 mn) pour suivre la penetration du front de la brise de mer pres des cotes tunisiennes et libyennes. Les cumulus materialisant le front commencent a apparaitre sur le continent environ 4 heures apres le lever du soleil; ils sont distinguables par un simple traitement visuel ou d’une facon numerique, ce qui a permis le calcul automatique de leurs vitesses. Ces dernieres sont faibles (moins de 5 m/s). Les images satellitaires ainsi que les donnees des stations meteorologiques fixes montrent une acceleration en fin de journee du front de la brise de mer qui peut penetrer jusqu’a environ 80 km dans les terres en Tunisie et environ 110 km a l’est de la Libye a des latitudes plus basses et non contrariees par un vent synoptique. L’extension verticale de la brise atteint environ 1000 m d’apres le radiosondage de Tunis-Carthage.
