description: Current agricultural production systems face challenges of poor economic returns, soil fatigue and negative environmental outcomes from excess use of nitrogenous fertilizers, especially in wheat production under middle gangetic plains. To overcome these challenges, the current study was conducted to optimize nitrogen management in different wheat genotypes with precision nitrogen management tools and approaches. The field experiment was laid out in split-plot design, with three genotypes assigned to the main plot and six nitrogen management practices to the sub-plot. The soil of the experimental field was sandy loam in texture, with low levels of organic carbon and available nitrogen, and medium levels of available phosphorus and potassium. Results revealed that the HD-2967 genotype outperformed others in terms of growth, grain yield (4.7 and 4.81 t ha−1), gross return (1417.41 and 1505.48 US$ ha−1), net return (953.43 and 1019.76 US$ ha−1), and B-C ratio (2.04 and 2.08) in 2015-16 and 2016-17, respectively. Among the nitrogen management practices, application of 150 kg N ha−1 in three equal splits demonstrated improved crop growth, grain yield (4.7 and 4.81 t ha−1), and economic returns (gross return, 1500.40 and 1607.65 US$ ha−1, net return, 1025.40 and 1110.38 US$ ha−1 and B: C ratio, 2.17 and 2.23) in 2015-16 and 2016-17, respectively. However, it resulted in higher nitrogen losses. Green seeker guided N application significantly reduced apparent nitrogen losses compared to all other nitrogen applied treatments. These findings provide valuable insights for optimizing wheat production by selecting appropriate genotypes and implementing precision nitrogen management techniques to enhance yield, profitability, and environmental sustainability.

description: We have studied the fundamental rotational relaxation and excitation collision of OH- J=0 1 with helium at different collision energies. Using state-selected photodetachment in a cryogenic ion trap, the collisional excitation of the first excited rotational state of OH- has been investigated and absolute inelastic collision rate coefficients have been extracted for collision temperatures between 20 and 35 K. The rates are compared with accurate quantum scattering calculations for three different potential energy surfaces. Good agreement is found within the experimental accuracy, but the experimental trend of increasing collision rates with temperature is only in part reflected in the calculations.

local government amalgamation
consensus-building

description: Municipal boundary reform (municipal amalgamation) has been done in many countries in recent years as the result of a push to enlarge the size and coverage of local government units, which in turn is driven mainly by the prospect of economies of scale. However, in a notable body of previous literature, the enlargement of local government has not led to reduction of public expenditures. Decision-making before amalgamation might affect to public expenditure after amalgamation. This study uses Japanese municipal-level data and argues for a relation between the choice of public administration distribution method and expenditure after amalgamation. The results show that a plan for distributed or decentralized facility method is more likely to be adopted in a larger administrative jurisdiction and in one with large differences in finances or political structures between amalgamated sub-regions. In turn, a plan for distributed facilities has the effect of pushing up administrative expenditure.

description: Most conventional phosphorous (P) fertilizers are highly soluble, which favors P retention in the solid phase of the soil, and this condition hinders P availability to plants. Alternative P fertilizers, such as organominerals and struvite, have a slow release of nutrients into the soil, which in turn favors P uptake by plants; nevertheless, soil acidification caused by nitrogen (N) fertilizers can reduce P availability in the soil. In his study, we assessed the effect of N fertilizers on P availability for maize (Zea mays) grown in tropical soils with alternative P fertilizers. An experiment was set up in columns under greenhouse conditions with maize in two cultivation cycles in two soils with contrasting textures (medium and clayey textures), two N fertilizers (calcium nitrate - CN - and ammonium sulfate - AS), three P fertilizers (triple superphosphate - TSP -, organomineral - OM - and struvite - ST), and a control treatment (without addition of P and N fertilizers). At 45 days after emergence, we measured the biomass production and the N and P contents in plants to calculate fertilization efficiency as well as the soil P content. AS promoted the highest aboveground N accumulation, whereas the highest efficiency was obtained with CN. The alternative P sources did not differ in terms of P availability when combined with both N sources. Soil textures were sensitive to fertilizer combination. Further studies are needed to assess struvite interaction with other elements in the soil and the P release kinetics to plants.

description: The quantum damped harmonic oscillator is described by the master equation with usual Lindblad form. The equation has been solved completely by us in arXiv : 0710.2724 [quant-ph]. To construct the general solution a few facts of representation theory based on the Lie algebra $su(1,1)$ were used. In this paper we treat a general model described by a master equation with generalized Lindblad form. Then we examine the algebraic structure related to some Lie algebras and construct the interesting approximate solution.

description: Phosphocreatine (PCr) was reduced in carp muscle by exercise or hypoxia at 15°C and 25°C in order to assess the influence of pH and temperature in PCr synthesis in vivo. Intramuscular PCr levels and intracellular pH (pH,) values were determined by 31P-NMRS. Exercise resulted in a significantly more acidic pHi than following hypoxia, differing by 0.38 and 0.44 pH units at 15°C and 25°C, respectively. The lower pH values in exercised carp slowed the recovery of PCr compared with posthypoxic fish, requiring a four-fold increase in the amount of time necessary to rebuild PCr levels. Throughout the recovery period. PCr levels following hypoxia were consistently and significantly higher than those following exercise. Intracellular pH continued to fall for up to over two hours, dropping to less than 6.3 and 6.7 following exercise and hypoxia, respectively. This continuing decline in pHi was correlated with the rise in PCr levels up to the time when PCr was nearly recovered. During hypoxia, 25°C acclimated carp depleted PCr stores more quickly than those at 15°C, temperature had no effect on the time for recovery of either PCr or pHi.

description: Conventional wisdom has it that economic training and education
tends to produce less cooperative people – where cooperation means
following group-oriented goals. This issue has attracted particular
attention in discussions of the current economic crisis where it was
asked if increasing marketization of societies has created an environment
encouraging amoral selfish behavior of financial intermediaries
and other economic agents. We provide some evidence against this
claim with the help of an experiment, using an investment game with
a public-goods character. Modest guidance of strategic abilities increases
the degree of cooperation if the institutional setting permits
reputation building. We thus conclude that economic practice can
enhance cooperation in a socially stable environment.

description: Due to the escalating demand for conventional potassium sources, and their unavailability in many African countries, there is a growing interest in hydrothermally treated igneous rocks as viable alternatives. These materials exhibit promising potential in enhancing potassium release, comparable to traditional sources like muriate of potash (M.O.P.). However, it remains uncertain whether they can adequately fulfill the nutrient requirements of plants. In this study, we evaluated nutrient balance in ryegrass (Lolium multiflorum) using raw and hydrothermally treated K-bearing silicate rocks as fertilizers. The Compositional Nutrient Diagnostic (CND) approach was used to assess the plants’ nutrient status, involving identification of high-yield subpopulations, and setting a yield cutoff. We derived a theoretical threshold for nutrient imbalance (CNDr2) using statistical methods like the chi-square distribution function and low-yield subpopulation proportion. CNDr2 was validated via Cate–Nelson partition and sum of squared individual nutrient indexes. Results showed a yield cutoff of 37.759 kg ha−1, distinguishing low-yield and high-yield subpopulations based on cumulative variance ratio functions from survey data. The theoretical threshold derived using the chi-square function was 10.1, subsequently validated by the Cate–Nelson method. Critical CND nutrient indices were symmetrical around zero, but their sum indicated foliar nutrient imbalance, notably zinc, potassium, and copper excess, attributed to 20 interactions identified (4 synergetic and 16 antagonistic). This study underscores hydrothermal treatment’s efficacy in improving nutrient availability and achieving a balanced nutrient profile compared to raw materials. It offers a promising solution for enhancing agricultural productivity, especially in tropical regions like Africa, where traditional sources are scarce.

description: Machine learning is widely used in developing computer-aided diagnosis (CAD) schemes of medical images. However, CAD usually computes large number of image features from the targeted regions, which creates a challenge of how to identify a small and optimal feature vector to build robust machine learning models. In this study, we investigate feasibility of applying a random projection algorithm to build an optimal feature vector from the initially CAD-generated large feature pool and improve performance of machine learning model. We assemble a retrospective dataset involving 1,487 cases of mammograms in which 644 cases have confirmed malignant mass lesions and 843 have benign lesions. A CAD scheme is first applied to segment mass regions and initially compute 181 features. Then, support vector machine (SVM) models embedded with several feature dimensionality reduction methods are built to predict likelihood of lesions being malignant. All SVM models are trained and tested using a leave-one-case-out cross-validation method. SVM generates a likelihood score of each segmented mass region depicting on one-view mammogram. By fusion of two scores of the same mass depicting on two-view mammograms, a case-based likelihood score is also evaluated. Comparing with the principle component analyses, nonnegative matrix factorization, and Chi-squared methods, SVM embedded with the random projection algorithm yielded a significantly higher case-based lesion classification performance with the area under ROC curve of 0.84+0.01 (p<0.02). The study demonstrates that the random project algorithm is a promising method to generate optimal feature vectors to help improve performance of machine learning models of medical images.

description: We propose a basic mechanism for isochronal synchrony and communication with mutually delay-coupled chaotic systems. We show that two Ikeda ring oscillators (IROs), mutually coupled with a propagation delay, synchronize isochronally when both are symmetrically driven by a third Ikeda oscillator. This synchronous operation, unstable in the two delay-coupled oscillators alone, facilitates simultaneous, bidirectional communication of messages with chaotic carrier waveforms. This approach to combine both bidirectional and unidirectional coupling represents an application of generalized synchronization using a mediating drive signal for a spatially distributed and internally synchronized multi-component system.

description: How to ban the fraudulent use of performance-enhancing drugs is
an issue in all professional – and increasingly in amateur – sports. The
main effort in enforcing a “clean sport” has concentrated on proving
an abuse of performance-enhancing drugs and on imposing sanctions
on teams and athletes.
An investigation started by Freiburg university hospital against two of
its employees who had been working as physicians for a professional cycling
team has drawn attention to another group of actors: physicians.
It reveals a multi-layered contractual relations between sports teams,
physicians, hospitals, and sports associations that provided string incentives
for the two doctors to support the use performance-enhancing
drugs. This paper argues that these misled incentives are not singular
but a structural part of modern sports caused by cross effects between
the labor market for sports medicine specialists (especially if they are
researchers) and for professional athletes.

description: We present a quantum theory for one-dimensional spin-1/2 multiferroics, where the vector spin chirality couples with the electric polarization. Based on exact diagonalization and bosonization, it is shown that quantum fluctuations appreciably reduce the chiral ordering amplitude and the associated ferroelectric polarization. This yields nearly collinear spin correlations in short-range scales, in qualitative agreement with recent neutron scattering experiments. There appear gapless chirality excitations described by phasons and new solitons, which can be experimentally verified from the low-energy dielectric response.

description: Low soil phosphorus (P) availability is a limiting factor for crop production. Application of livestock manure as organic fertilizer can increase soil P availability, but may cause soil contamination with antibiotics such as sulfadiazine (SD), thus adversely affecting plant growth and nutrient uptake. The effects of P (0 and 50 mg kg−1) and SD (0, 1, 10, and 100 mg kg−1) levels on plant growth, root development, and nitrogen (N) and P uptake of maize and soybean were examined in a pot experiment using a loess soil as the test soil. High levels of SD considerably inhibited plant growth of both crops. Both P fertilization and SD negatively affected root development of both crops, especially at higher SD levels. For both crops, the average root diameter and the proportion of thick roots increased with increasing soil SD level. When soil SD level was ≤10 mg kg−1, the effects of P fertilization and SD on plant N and P concentrations, and N:P, N- and P-utilization efficiency were not significant in most cases. The effects of SD on plant N and P nutrition could not be of a great concern when soil SD level was ≤10 mg kg−1. Overall, soil SD pollution could reduce plant biomass and inhibit root development of soybean and maize, with a stronger effect on root development than on plant biomass at a high soil SD level (≥10 mg kg−1). In agricultural production, attention should be paid to soil SD pollution via manure application.

description: Analytical solution for optical trapping force on a spherical dielectric particle for an arbitrary positioned focused beam is presented in a generalized Lorenz-Mie and vectorial diffraction theory. In this case the exact electromagnetic field is considered in the focal region. A double tweezers setup was employed to perform ultra sensitive force spectroscopy and observe the forces, demonstrating the selectively couple of the transverse electric (TE), transverse magnetic (TM) modes by means of the beam polarization and positioning, and to observe correspondent morphology-dependent resonances (MDR) as a change in the optical force. The theoretical prediction of the theory agrees well with the experimental results. The algorithm presented here can be easily extended to other beam geometries and scattering particles.

description: We investigate the motives of pro-social behavior in collective decisions in an economic experiment. It compares individual behavior in private and collective decisions in a unified experimental setup. Subjects are given an individual endowment and have to decide how much of it to donate to charity. The experiment is combined with two long questionnaires that provide us with background information on subjects and enables us to learn more about the motives driving their behavior. Contrary to theoretical predictions, the distribution of amounts donated individually is remarkably similar to the distribution of amounts proposed for collective
donation. In regressions, we find individual donations to be driven by consequentialist motives, social norms and moral convictions. In collective decisions, neither the motiverelated variables nor any of the control variables are found significant. Comparing subjects’ affective state before and after the experiment, we find that individual donations create a feeling of warm glow while collective donations do not. On the other hand, the change in affective state in the collective decision is higher the higher the amount proposed for the collective donation. This pattern is consistent with expressive motives.

description: Performance budgeting schemes in the public sector have to operate with imperfect performance measures. We argue that these imperfections generate incentives for the potential recipients of performance-based funds to use up resources in socially wasteful influence activities. We develop a game-theoretical model to analyse the trade-off between the efficiency-enhancing effect of performance budgeting and the social waste it induces. Comparing a performance signal based on recipients’ effort to a signal based on their output shows that a) the former evokes more social waste while the latter amplifies inequality in the amount of public services across districts. Performance budgeting schemes using the outputbased signal yield welfare gains in a wide range of parameter constellations while the applicability of PB-schemes using the effort-based signal is limited. We also show that welfare losses arise when the government is opportunistic. Our model can be applied to the very similar trade-off emerging with the use of conditional grants in federalist countries.

Our central result is the determination of the screened real-part of this potential, and we reconfirm the presence of an imaginary part. The real part is intimately related to the back-reaction of the static sources onto the gauge fields, incorporated via Gauss's law. Differences in the treatment of static sources in quantum and classical lattice gauge theory are discussed.

An Investigation of conceptuses with placental chromosomal mosaicism for the presence of germline mosaicism
Creators: name: Stavropoulos, Dimitri James
Publisher: name: University of British Columbia
Year: 2009

description: Confined placental mosaicism (CPM) is detected in approximately 1-2% of viable pregnancies and has been defined as a dichotomy between the chromosomal constitution of the placental and embryonic/fetal tissues. An investigation for the presence of trisomy in the germ cells was initiated in cases diagnosed with CPM since we suspect that the stroma of the placenta and the primordial germ cells (PGCs) have a common developmental origin. Placental and fetal tissues from one conceptus diagnosed with CPM for trisomy 7 and two conceptuses with CPM for trisomy 16, were analyzed using fluorescence in situ hybridization (FISH). Post-termination conventional cytogenetic analysis of amnion and chorionic stroma from case 1 showed only diploid cells in the amnion and mosaicism for trisomy 7 in the stroma. FISH analysis of formalin fixed - paraffin embedded tissues showed significant levels of trisomy in the placenta while all fetal tissues analyzed including testis were diploid. For Case 2, high levels of trisomy 16 were detected using FISH in both chorionic stroma and cytotrophoblast of the placenta while fetal somatic tissues where diploid. FISH analysis of meiotic oocytes showed significant levels of trisomy 16. In case 3, prenatal metaphase analysis of cytotrophoblast and stroma from chorionic villus sampling showed only 47,XX,+16. Culture of placental vill i after termination showed only trisomy 16 while cultures of multiple fetal tissues showed no evidence of trisomy. FISH analysis of formalin fixed - paraffin embedded lung and meiotic oocytes also failed to show evidence of trisomy 16. The results from Case 2 suggest that conceptuses diagnosed with mosaicism in the chorionic stroma are at risk of exhibiting chromosomal mosaicism in their germ cells. Future studies in similar cases are needed to understand the effects this may have on human fertility in the reproductive period.

description: In type II seesaw utilized to explain the observed neutrino masses and mixings, one extends the Standard Model (SM) by introducing scalar fields which transform as a triplet under the electroweak gauge symmetry. New scalar couplings involving the Higgs doublet then appear and, as we show, these have important implications for the Higgs boson mass bounds obtained using vacuum stability and perturbativity arguments. We identify, in particular, regions of the parameter space which permit the SM Higgs boson to be as light as 114.4 GeV, the LEP2 bound. The triplet scalars include doubly charged particles whose masses could, in principle, be in the few hundred GeV range, and so they may be accessible at the LHC.

description: We investigate the process by which a water molecule diffuses on the surface of an Al(111) electrode under constant bias voltage by first-principles density functional theory. To understand the diffusion path of the water on the Al(111), we calculated the minimum energy path (MEP) determined by the nudged elastic band method in combination with constant electron chemical potential (constant-$μ_{\rm e}$) methods. The simulation shows that the MEP of the water molecule, its adsorption site, and the activation barrier strongly depend on the applied bias voltage. This strong dependence of the water diffusion process on the bias voltage is in good agreement with the result of a previous scanning tunneling microscopy (STM) experiment. The agreement between the theoretical and experimental results implies that accurate treatment of bias voltage plays a significant role in understanding the interaction between the electric field and the surface of the material. Comparative studies of the diffusion process with the constant total number of electrons (constant-$N_\mathrm{e}$) scheme show that the absence of strong interaction between the molecular dipole and the electric field leads to a different understanding of how water diffuses on a metal surface. The proposed constant-$μ_{\rm e}$ scheme is a realistic tool for the simulation of reactions under bias voltage not only using STM but also at the electrochemical interface.

description: Agronomic bio-fortification remains a crucial focus area for enhancing wheat productivity and quality while alleviating environmental pressures. Micronutrient deficiencies, particularly in iron (Fe) and zinc (Zn), persist among the Indian population, especially affecting women. These deficiencies can be effectively addressed through agronomic bio-fortification of wheat grains. To tackle this issue, a comprehensive multilocation (4) field experiment was conducted, incorporating four high-yielding wheat cultivars (HD-3226, HI-1544, DBW-187, and PBW-1-Zn) alongside six foliar fertilizer applications (Control, 2% S, 2% N, 0.5% ZnSO4.7H2O, 1% KCl, and combined treatments) during 2021-22 and 2022-23 utilizing a split-plot design with three replications. Analysis over the years revealed that significant impacts of location and cultivar on yield and its attributes, and Fe, Zn, and protein content of grains. Warmer locations like Hisar exhibited higher yields primarily due to significantly increased earheads/m2 and grains number/m2 compared to other locations. Moreover, Fe content in wheat grains was notably higher in Gurdaspur followed by Hisar, surpassing Ludhiana. Notably, cultivar DBW-187 outperformed others with a 14.75% higher grain yield than the least yielding cultivar, HI-1544. PBW-1-Zn exhibited the highest grain Fe and Zn content among the cultivars studied. The interaction between cultivar and location significantly influenced all yield parameters and grain Fe content. Foliar spray of ZnSO4 (0.5%) during stem elongation and milk stages resulted in significantly higher grain Zn content compared to applications of KCl (1.0%), N (2.0%), and S (2.0%) alone, with an increase of 9.9% over no spray. In conclusion, the selection of appropriate cultivars tailored to specific regions, coupled with strategic agronomic bio-fortification approaches, is imperative for enhancing wheat productivity and grain quality, thereby ensuring nutritional security.

description: We discuss the necessary symmetry conditions and the different ways in which they can be physically realized for the occurrence of ferromagnetism accompanying the loop current orbital magnetic order observed by polarized neutron-diffraction experiments or indeed any other conceivable principal order in the under-doped phase of cuprates. We contrast the Kerr effect experiments in single crystals observing ferromagnetism with the direct magnetization measurements in large powder samples, which do not observe it. We also suggest experiments to resolve the differences among the experiments, all of which we believe to be correct.

description: In this paper, we test whether public preferences for price stability (obtained from the Eurobarometer survey) are actually reflected in the interest rates set by eight central banks. We estimate augmented Taylor (1993) rules for the period 1976–1993 using the dynamic GMM estimator. We find, first, that interest rates do reflect society’s preferences since the central banks raise rates when society’s inflation aversion is above its long‐run trend. Second, the reaction to inflation is non‐linearly increasing in the degree of inflation aversion. Third, this emphasis on fighting inflation does not have a detrimental effect on output stabilization. We conclude with some implications concerning the democratic legitimation of central banks.

description: We analyze a suspension of deformable particles in a pressure-driven flow. The suspension is composed of neutrally buoyant initially spherical particles and a Newtonian carrier fluid, and the flow is solved by means of direct numerical simulations, using a fully Eulerian method based on a one-continuum formulation. The solid phase is modeled with an incompressible viscous hyperelastic constitutive relation, and the flow is characterized by three main dimensionless parameters, namely the solid volume fraction, the Reynolds and capillary numbers. The dependency of the effective viscosity on these three quantities is investigated to study the inertial effects on a suspension of deformable particles. It can be observed that the suspension has a shear-thinning behavior, and the reduction in effective viscosity for high shear rates is emphasized in denser configurations. The separate analysis of the Reynolds and capillary numbers reveal that the effective viscosity depends more on the capillary than on the Reynolds number. In addition, our simulations exhibit a consistent tendency for deformable particles to move towards the center of the channel, where the shear rate is low. This phenomenon is particularly marked for very dilute suspensions, where a whole region near the wall is empty of particles. Furthermore, when the volume fraction is increased this near-wall region is gradually occupied, because of higher mutual particle interactions. Deformability also plays an important role in the process. Indeed, at high capillary numbers, particles are more sensitive to shear rate variations and can modify their shape more easily to accommodate a greater number of particles in the central region of the channel.

description: The possible existence of stable axial octupole and tetrahedral deformations is investigated in $^{80}$Zr and $^{98}$Zr. HFBCS calculations with parity projection have been performed for various parametrizations of the Skyrme energy functional. The correlation and excitation energies of negative parity states associated with shape fluctuations have been obtained using the generator coordinate method (GCM). The results indicate that in these nuclei both the axial octupole and tetrahedral deformations are of dynamic character and possess similar characteristics. Various Skyrme forces give consistent results as a function of these two octupole degrees of freedom both at the mean-field level as well as for configuration mixing calculations.

title: Egg production, flight velocity and predation risk in birds
Creators: name: Veasey, Jake S.

Subjects: subject: Ecology.

description: The costs of reproduction can be defined as the trade-off between present and future reproduction, where current reproduction may diminish future reproductive success of the parent and/or of the parent's offspring. One potential cost of reproduction in birds may be a reduction in the ability of the female to escape from predators due to a reduction in maximal flight velocity. Such a reduction in flight performance may come about in laying females as a result of an increase in mass over the laying period, and a reduction in flight muscle condition. The result of such a reduction in the flight velocity of wild birds would be to increase the susceptibility of those birds to capture by predators once attacked. To investigate the potential of egg production to affect flight velocity and consequently predation risk, the individual effects of body mass and muscle condition needed to be determined. Contrary to theoretical studies which have indicated that body mass might significantly affect flight velocity in birds, no such relationship was found in startled zebra finches (Taeniopygia guttata), a finding supported by a number of other empirical studies on other species. To determine whether muscle loss is significant in affecting flight velocity, the physiological costs of reproduction and consequently the extent to which females lost muscle condition were manipulated. This was achieved by encouraging females to lay large or small clutches on high or low quality protein diets, and measuring the changes in muscle condition and flight velocity during the course of laying a clutch. A strong positive relationship was found to exist between changes in muscle condition and changes in flight velocity. Treatments in which birds exhibited the largest declines in muscle condition, were associated with the largest declines in flight velocity, hi contrast to this, those treatments in which birds lost the least muscle condition were associated with actual improvements in flight performance, that is to say, birds flew faster at the end of a clutch than at the beginning. These changes were independent of body mass and occurred post-laying indicating that it is the cost of egg production that is critical in affecting flight velocity rather than the cost of carrying eggs as had previously been suggested. Moreover, it is demonstrated that independently of diet and changes in body mass, increased reproductive output decreases maximal flight velocity mediated by an increase in muscle loss. This is the first demonstration of a physiological trade-off between resource allocation to reproduction and the maintenance of musculature critical to an animal's escape response.

description: We use MPC voting records to predict changes in the volume of asset purchases. We find, first, that minority voting favoring an increase in the volume of asset purchases raises the probability of an actual increase at the next meeting. Second, minority voting supporting a higher Bank Rate decreases the likelihood of further asset purchases.

description: A sequential estimator based on the Ensemble Kalman Filter for Data Assimilation of fluid flows is presented in this research work. The main feature of this estimator is that the Kalman filter update, which relies on the determination of the Kalman gain, is performed exploiting the algorithmic features of the numerical solver employed as a model. More precisely, the multilevel resolution associated with the multigrid iterative approach for time advancement is used to generate several low-resolution numerical simulations. These results are used as ensemble members to determine the correction via Kalman filter, which is then projected on the high-resolution grid to correct a single simulation which corresponds to the numerical model. The assessment of the method is performed via the analysis of one-dimensional and two-dimensional test cases, using different dynamic equations. The results show an efficient trade-off in terms of accuracy and computational costs required. In addition, a physical regularization of the flow, which is not granted by classical KF approaches, is naturally obtained owing to the multigrid iterative calculations. The algorithm is also well suited for the analysis of unsteady phenomena and, in particular,for potential application to in-streaming Data Assimilation techniques.
