Fusarium incarnatum-Equiseti

description: Fusarium incarnatum-equiseti species complex (FIESC) phylogeny The 11 isolates belonging to the FIESC were assessed using a more inclusive analysis based on five loci (cmdA, ITS, LSU, rpb2 and tef1; Fig. 3). The alignment consisted of a total 2 746 char- acters (cmdA 653, ITS 510, LSU 562, rpb2 597 and tef1 424), from 93 isolates, including all the phylogenetic clades known in this species complex plus two outgroup taxa (Fusarium circinatum NRRL 25331 and F. fujikuroi NRRL 13566). Multi-gene phy- logenetic inference was able to recognise six new phylogenetic species in the FIESC. The number of new phylogenetic species recognised is equally distributed in the incarnatum clade and the equiseti clade (three new phylospecies each) sensu O’Donnell et al. (2009). In the incarnatum clade, isolates InaCC F 940, InaCC F 941, Indo167, InaCC F 964, Indo186, and Indo188 clustered in a distinct clade (55 bp/0.99 pp) closely related to the phylogenetic species FIESC-16 which is introduced here as phylogenetic species FIESC-32. These isolates were obtained from five different banana variety hosts in Sulawesi and Kalimantan. The other two new species in the incarnatum clade are monotypic lineages represented by isolate Indo161 (99 bp/1 pp) closely related to FIESC-26 and isolate InaCC F 965 (50 bp/ 1 pp) closely related to FIESC-24, introduced as phylogenetic species FIESC-33 and FIESC-34, respectively. In the equiseti clade, three isolates: Indo174 (99 bp/1 pp) closely related to FIESC-1; Indo175 (-/1 pp) and InaCC F 963 (55 bp/1 pp), both isolates closely related to FIESC-13, formed monotypic lineages which are introduced here as FIESC-29, FIESC-30, and FIESC-31, respectively. These phylogenetic species were isolated from two banana varieties in relatively close proximity in South Kalimantan.

description: The recent exquisite Gaia astrometric, photometric, and radial velocity (RV) measurements resulted in a substantial advancement for the determination of the orbits for old star clusters, including the oldest Milky Way globular clusters (MW GCs). The main goal of this paper is to use the Gaia DR3 and the VVVX measurements to obtain the orbits for nearly a dozen new Galactic GC candidates that have been poorly studied or previously unexplored. We use the Gaia DR3 and VVVX databases to identify bonafide members of the Galactic GC candidates: VVV-CL160, Patchick122, Patchick125, Patchick126, Kronberger99, Kronberger119, Kronberger143, ESO92-18, ESO93-08, Gaia2, and Ferrero54. The relevant mean cluster physical parameters are derived (distances, Galactic coordinates, proper motions, RVs). We measure accurate mean RVs for the GCs VVV-CL160 and Patchick126, using observations acquired at the Gemini-South telescope with the IGRINS high-resolution spectrograph. Orbits for each cluster are then computed using the GravPot16 model, assuming typical Galactic bar pattern speeds. We reconstruct the orbits for these clusters for the first time. These include star clusters with retrograde and prograde orbital motions, both in the Galactic bulge and disk. Orbital properties, such as the mean time-variations of perigalactic and apogalactic distances, eccentricities, vertical excursions from the Galactic plane, and Z-components of the angular momentum are obtained for our sample. Our main conclusion is that, based on the orbital parameters, Patchick125 and Patchick126 are genuine MW bulge/halo GCs; Ferrero54, Gaia2 and Patchick122 are MW disk GCs. The orbits of Kronberger99, Kronberger119, Kronberger143, ESO92-18, and ESO93-08 are more consistent with old MW disk open clusters. VVV-CL160 falls very close to the Galactic centre, but reaches larger distances beyond the Sun, thus its origin is still unclear.

description: This dissertation studies three applications of the tools of coupling and unimodularity in stationary settings. The first application is to exact coupling of random walks. Conditions for admitting a successful exact coupling are given that are necessary and in the Abelian case also sufficient. This solves a problem posed by H. Thorisson. The second application is centered on the random graph generated by a Doeblin-type coupling of discrete time processes whereby when two paths meet, they merge. This random graph is studied through a novel subgraph, called a bridge graph, generated by paths started in a fixed state. The bridge graph is then made into a unimodular network. The final application focuses on point-shifts of point processes on topological groups. Foliations and connected components generated by point-shifts are studied, and the cardinality classification of connected components is generalized to unimodular groups.

description: A quasi-exciton condensate is a phase characterized by quasi-long range order of an exciton (electron-hole pair) order parameter. Such a phase can arise naturally in a system of two parallel oppositely doped quantum wires, coupled by repulsive Coulomb interactions. We show that the quasi-exciton condensate phase can be stabilized in an extended range of parameters, in both spinless and spinful systems. For spinful electrons, the exciton phase is shown to be distinct from the usual quasi-long range ordered Wigner crystal phase characterized by power-law density wave correlations. The two phases can be clearly distinguished through their inter-wire tunneling current-voltage characteristics. In the quasi-exciton condensate phase the tunneling conductivity diverges at low temperatures and voltages, whereas in the Wigner crystal it is strongly suppressed. Both phases are characterized by a divergent Coulomb drag at low temperature. Finally, metallic carbon nanotubes are considered as a special case of such a one dimensional setup, and it is shown that exciton condensation is favorable due to the additional valley degree of freedom.

description: The aim of this study is to invistgate the characteristics of Si-MOSFET with
18 nm length of ion implemented channel. Technology computer aided design
(TCAD) tool from Silvaco was used to simulate the MOSFET’s designed
structure in this research. The results indicate that the MOSFET with 18 nm
channel length has cut-off frequency of 548 GHz and transconductance of
967 μS, which are the most important factors in calculating the efficiency and
improving the performance of the device. Also, it has threshold voltage of
(-0.17 V) in addition obtaining a relatively small DIBL (55.11 mV/V).
The subthreshold slope was in high value of 307.5 mV/dec. and this is one of the
undesirable factors for the device results by short channel effect, but it does not
reduce its performance and efficiency in general

description: Fusarium sambucinum species complex (FSSC) phylogeny The single Indonesian isolate in the FSSC was further analysed using a two-gene phylogeny based on rpb1 and rpb2 sequences. The analysis included a total of 2 461 characters (rpb1 854 and rpb2 1607) from a total of 21 isolates representing the FSSC and two outgroup taxa (F. circinatum NRRL 25331 and F. fujikuroi NRRL 13566). Isolate InaCC F 974 was identified as F. longipes (Fig. 4) based on phylogenetic inference. Pathogenicity Representative isolates from each species complex were tested for their pathogenicity against banana variety Cavendish (Fig. 5). Selected isolates included InaCC F 872, InaCC F 950, and InaCC F 992 (FFSC), InaCC F 962 (FIESC), InaCC F 974 (FSSC). None of the isolates was able to cause any disease symptoms in the inoculated plants. All of the isolates tested caused only slight discoloration in the corm without any further disease development.

description: Periodicity and modulation lie at the heart of modern electromagnetic, acoustic and mechanical engineering, dramatically altering the way in which waves interact with periodically structured media. The main idea driving the intense research into periodic systems is the fact that periodicity breaks the dependence on natural properties of constituent media and instead allows one to blend the responses of various materials and leverage their geometric shapes to obtain collective responses on demand. In the realm of electromagnetics, over the past two decades there has been an explosive surge of interest to artificially engineered time-invariant periodic structures thanks to numerous fascinating linear and nonlinear effects they enable. In this dissertation, I will present some transformative developments in the area of efficient nonlinear generation and wave mixing in thin 2D periodic structures based on multi-quantum-wells, as well as show the possibility to engineer to the great extent the dispersion topology of surface waves propagating along ideally thin conducting sheets with 1D spatial periodicity such as graphene ribbons. In parallel with the progress in obtaining desired responses in time-invariant periodic structures, significant progress is being made in applying temporal and synchronous spatial and temporal modulation to engage new degrees of freedom and extend the spectrum of achievable electromagnetic phenomena even further. In this dissertation, I will also show that spatiotemporal modulation applied to electronic networks holds a key to obtain ultrawideband and extremely compact delays far beyond those achievable in time-invariant systems. Spatiotemporal modulation also allows for all kinds of nonreciprocal devices to be seamlessly integrated in an electronic chip by overcoming the size and magnetic material incompatibility constraints. This fact holds a truly groundbreaking potential for future electronic devices and wireless systems by enabling their simultaneous transmit-and-receive operation. Finally, I will show that spatiotemporal modulation enables a direct translation of some of the most advanced and intricate concepts of condensed matter physics – topological insulators – to the realm of classical electronic circuits. Compared to standalone nonreciprocal devices, topologically-nontrivial electronic circuits provide an even larger toolbox to obtain various nonreciprocal functionalities by enforcing a wideband unidirectional transmission robust to defects and imperfections

Επίσης, κατά μέσο όρο μόνο το 40.1% των μαθητών -τριών πληρούσε τις προτεινόμενες συστάσεις των σιτηρών, το 7.46% των φρούτων, το 16.83% των λαχανικών, το 11.06% των γαλακτοκομικών και το 36.76% του κρέατος. Επιπλέον κατά μέσο όρο το 84% των μαθητών -τριών η διατροφή τους χρειάζεται βελτίωση σύμφωνα με την κατάταξη του Δείκτη Υγιεινής Διατροφής. Συμπεραίνεται ότι, η συντριπτική πλειοψηφία των μαθητών -τριών δεν πληροί τις προτεινόμενες συστάσεις ΦΔ και διατροφής παγκόσμιων οργανισμών υγείας.

description: Two-dimensional (2D) materials and Transition Metal Dichalcogenides (TMD) in particular are at the forefront of nanotechnology. To tailor properties for engineering applications, alloying strategies used for bulk metals in the last century need to be extended to this novel class of materials. Here we present a systematic analysis of the phase behaviour of substitutional 2D alloys in the TMD family on both the metal and chalcogenide site. The phase behaviour is quantified in terms of a metastability metric and benchmarked against systematic computational screening of configurational energy landscapes. The resulting Pettifor maps can be used to identify broad trends across chemical spaces and as starting point for setting up rational search strategies in phase space, thus allowing for targeted computational analysis of properties on likely thermodynamically stable compounds. The results presented here also constitute a useful guideline for synthesis of binary metal 2D TMDs alloys via a range of synthesis techniques.

description: We present a new algorithm, named Autonomous Gaussian Decomposition (AGD), for automatically decomposing spectra into Gaussian components. AGD uses derivative spectroscopy and machine learning to provide optimized guesses for the number of Gaussian components in the data, and also their locations, widths, and amplitudes. We test AGD and find that it produces results comparable to human-derived solutions on 21cm absorption spectra from the 21cm SPectral line Observations of Neutral Gas with the EVLA (21-SPONGE) survey. We use AGD with Monte Carlo methods to derive the HI line completeness as a function of peak optical depth and velocity width for the 21-SPONGE data, and also show that the results of AGD are stable against varying observational noise intensity. The autonomy and computational efficiency of the method over traditional manual Gaussian fits allow for truly unbiased comparisons between observations and simulations, and for the ability to scale up and interpret the very large data volumes from the upcoming Square Kilometer Array and pathfinder telescopes.

description: This paper comprises a SysML-based approach to support the model-driven engineering (MDE) of Manufacturing Automation Software Projects (MASP). The Systems Modeling Language (SysML) is adapted to define the SysML-AT (SysML for automation), a specialized language profile that covers (non-)functional requirements, corresponding software applications and properties of proprietary hardware components. Furthermore, SysML-AT supports an automated software generation for run-time environments conforming to IEC 61131-3. A prototypical tool support was realized for adapted SysML Parametric Diagrams (PD) inside an industrial automation software development tool. Coupling the model editor and online data from the provided run-time environment enables direct debugging inside the model. The approach was evaluated by several case studies and additional usability experiments. With the latter, the suitability of the MDE approach for future users was proven.

description: Recently, some general frameworks have been proposed as unifying theories for processes combining non-determinism with quantitative aspects (such as probabilistic or stochastically timed executions), aiming to provide general results and tools. This paper provides two contributions in this respect. First, we present a general GSOS specification format (and a corresponding notion of bisimulation) for non-deterministic processes with quantitative aspects. These specifications define labelled transition systems according to the ULTraS model, an extension of the usual LTSs where the transition relation associates any source state and transition label with state reachability weight functions (like, e.g., probability distributions). This format, hence called Weight Function SOS (WFSOS), covers many known systems and their bisimulations (e.g. PEPA, TIPP, PCSP) and GSOS formats (e.g. GSOS, Weighted GSOS, Segala-GSOS, among others). The second contribution is a characterization of these systems as coalgebras of a class of functors, parametric on the weight structure. This result allows us to prove soundness of the WFSOS specification format, and that bisimilarities induced by these specifications are always congruences.

description: The deepest all-sky survey available in the $γ$-ray band - the last release of the Fermi-LAT catalogue (4FGL-DR3) based on the data accumulated in 12 years, contains more than 6600 sources. The largest population among the sources is blazar subclass - 3743, $60.1\%$ of which are classified as BL Lacertae objects (BL Lacs) or Flat Spectrum Radio Quasars (FSRQs), while the rest are listed as blazar candidates of uncertain type (BCU) as their firm optical classification is lacking. The goal of this study is to classify BCUs using different machine learning algorithms which are trained on the spectral and temporal properties of already classified BL Lacs and FSRQs. Artificial Neural Networks, \textit{XGBoost} and LightGBM algorithms are employed to construct predictive models for BCU classification. Using 18 input parameters of 2219 BL Lacs and FSRQs, we train (80\% of the sample) and test (20\%) these algorithms and find that LightGBM model, state-of-the-art classification algorithm based on gradient boosting decision trees, provides the highest performance. Based on our best model, we classify 825 BCUs as BL Lac candidates and 405 as FSRQ candidates, however, 190 remain without a clear prediction but the percentage of BCUs in 4FGL is reduced to 5.1\%. The $γ$-ray photon index, synchrotron peak frequency, and high energy peak frequency of a large sample are used to investigate the relationship between FSRQs and BL Lacs (LBLs, IBLs, and HBLs).

description: Let $Λ$ be a finite dimensional algebra over an algebraically closed field. We exhibit slices of the representation theory of $Λ$ that are always classifiable in stringent geometric terms. Namely, we prove that, for any semisimple object $T \in Λ\text{-mod}$, the class of those $Λ$-modules with fixed dimension vector (say $\bf d$) and top $T$ which do not permit any proper top-stable degenerations possesses a fine moduli space. This moduli space, $\mathfrak{ModuliMax}^T_{\bf d}$, is a projective variety. Despite classifiability up to isomorphism, the targeted collections of modules are representation-theoretically rich: indeed, any projective variety arises as $\mathfrak{ModuliMax}^T_{\bf d}$ for suitable choices of $Λ$, $\bf d$, and $T$. In tandem, we give a structural characterization of the finite dimensional representations that have no proper top-stable degenerations.

description: For an arbitrary velocity field $\mathbf{v}$ defined on a finite, fixed spatial domain, we find the closest rigid-body velocity field $\mathbf{v}_{RB}$ to $\mathbf{v}$ in the $L^2$ norm. The resulting deformation velocity component, $\mathbf{v}_{d}=\mathbf{v-\mathbf{v}}_{RB}$, turns out to be frame-indifferent and physically observable. Specifically, if $\mathbf{Q}_{\text{RB}}(t)$ is the rotation tensor describing the motion of the closest rigid body frame, then $\mathbf{v}$ is seen as $\mathbf{Q}_{\text{RB}}^{T}\mathbf{v}_{d}$ by an observer in that frame. As a consequence, the momentum, energy, vorticity, enstrophy, and helicity of the flow all become frame-indifferent when computed from the deformation velocity component $\mathbf{v}_{d}$.

description: We investigate the Hadamard function and the vacuum expectation value of the current density for a charged massive scalar field on a slice of anti-de Sitter (AdS) space described in Poincaré coordinates with toroidally compact dimensions. Along compact dimensions periodicity conditions are imposed on the field with general phases. Moreover, the presence of a constant gauge field is assumed. The latter gives rise to Aharonov-Bohm-like effects on the vacuum currents. The current density along compact dimensions is a periodic function of the gauge field flux with the period equal to the flux quantum. It vanishes on the AdS boundary and, near the horizon, to the leading order, it is conformally related to the corresponding quantity in Minkowski bulk for a massless field. For large values of the length of the compact dimension compared with the AdS curvature radius, the vacuum current decays as power-law for both massless and massive fields. This behavior is essentially different from from the corresponding one in Minkowski background, where the currents for a massive field are suppressed exponentially.

description: Historically, economists have, whenever possible, used linear equations to model economic phenomena, because they are easy to manipulate and usually yield unique solutions. However, it now has become impossible to ignore the fact that many important and interesting phenomena are not amenable to such treatment. With the chaos theory it is possible to take into account those aspects of the phenomena. The theory of chaos is challenging many of the fundamental presuppositions of the traditional older Newtonian world view of science. The implications of the new science vision will be explored starting from physics to arrive at economics in terms of their challenges to the traditional methodological views. In particular the implications of chaos control theory for the economics will be highlighted. The purpose of this paper is to show why the economists can no longer ignore that economics is a complex system and how the application of chaos control methods could improve the system's economic performance.

description: GX 301-2 is a high-mass X-ray binary (HMXB) with strong stellar outflows. The evolution of these binaries can be closely related with the interstellar environment due to strong wind interactions. We try to constrain the energy injected in the interstellar medium by GX 301-2 through stellar wind using HAWK-I and Herschel data. We analysed HAWK-I images in four different filters (Br$γ$, H$_2$, J, and Ks) and tried to retrieve signatures of the impact of GX 301-2 on its environment. We used Herschel data to outline the interstellar medium and the Gaia DR3 catalogue to infer the proper motion of GX 301-2. Finally, we estimated the energy injected in the interstellar medium since the first supernova event of the HMXB. Using both HAWK-I and Herschel images, we deduce an approximation of the total mass injected from GX~301-2 in the interstellar medium of $M_{\rm inj} = 3.05 ^{+0.05}_{-0.03} 10^{-2} M_{\odot}$.

description: Based on techniques developed in the previous papers of this series, we investigate the impact of galaxy-cluster mergers on the order statistics of the largest Einstein radii. We show that the inclusion of mergers significantly shifts the extreme value distribution of the largest Einstein radius to higher values, typically increasing the expected value by ${\sim}10\%$. A comparison with current data reveals that the largest observed Einstein radius agrees excellently well with the theoretical predictions of the $Λ$CDM model at redshifts $z > 0.5$. At redshifts $z < 0.5$, our results are somewhat more controversial. Although cluster mergers also increase the expected values of the order statistics of the $n$ largest Einstein radii by ${\sim}10\%$, the theoretically expected values are notably lower (${\sim}3σ$ deviation for $n = 12$) than the largest Einstein radii of a selected sample of SDSS clusters in the redshift range $0.1 \leq z \leq 0.55$. The uncertainties of the observed Einstein radii are still large, however, and thus the measurements need to be carefully revised in future works. Therefore, given the premature state of current observational data, overall, there is still no reliable statistical evidence for observed Einstein radii to exceed the theoretical expectations of the standard cosmological model.

description: We study aggregations for ordinary differential equations induced by fluid semantics for Markovian process algebra which can capture the dynamics of performance models and chemical reaction networks. Whilst previous work has required perfect symmetry for exact aggregation, we present approximate fluid lumpability, which makes nearby processes perfectly symmetric after a perturbation of their parameters. We prove that small perturbations yield nearby differential trajectories. Numerically, we show that many heterogeneous processes can be aggregated with negligible errors.

description: We discuss the concepts of fine and coarse moduli spaces in the context of finite dimensional algebras over algebraically closed fields. In particular, our formulation of a moduli problem and its potential strong or weak solution is adapted to classification problems arising in the representation theory of such algebras. We then outline and illustrate a dichotomy of strategies for concrete applications of these ideas. One method is based on the classical affine variety of representations of fixed dimension, the other on a projective variety parametrizing the same isomorphism classes of modules. We state sample results and give numerous examples to exhibit pros and cons of the two lines of approach. The juxtaposition highlights differences in techniques and attainable goals.

description: People do not always perceive their social world dispassionately; they often engage in motivated social evaluation. That is, people often do not evaluate themselves or other people objectively, but rather in a way that conforms to how they want to see the social target (i.e., a desired directional conclusion). For example, research shows that people tend to see themselves and liked others in an unrealistically positive light (Kruger, 1999; Tajfel & Turner, 2004; Taylor & Brown, 1988). Several researchers have posited biased searches through memory as an underlying mechanism supporting the phenomenon of seeing people in a certain light (Showers & Cantor, 1985; Kunda, 1990, Dunning, 2015). That is, it has been suggested that when aiming to paint a social target in a certain light people search through their memories or beliefs in ways that help them find information to support their desired directional conclusion. However, the methods used in existing research have made it difficult to understand if social evaluations that have been labeled as motivated actually reflect people striving for desired directional conclusions and what role biased memory searches may play. The proposed dissertation research addresses two overarching questions to understand the role of biased searches through memory in social evaluation. Research Question 1: What is the role of a) biased searches through memory and b) directional conclusions in the greater reported memory for positive self-relevant feedback (compared to negative self-relevant feedback; Studies 1, 2, & 3)? Research Question 2: Does biased searching through memory operate similarly when aiming to paint someone in a particular light (regardless of the directional conclusion) or only in a flattering light (Study 4)? A combination of experimental, neuroimaging (i.e., Event Related Potential), and computational modeling (i.e., Signal Detection Theory and Drift Diffusion Model) methods are used to address these questions.

description: It was recently proposed that there exists a "gateway" in the orbital parameter space through which Centaurs transition to Jupiter-family Comets (JFCs). Further studies have implied that the majority of objects that eventually evolve into JFCs should leave the Centaur population through this gateway. This may be naively interpreted as gateway Centaurs being pristine progenitors of JFCs. This is the point we want to address in this work. We show that the opposite is true: gateway Centaurs are, on average, more thermally processed than the rest of the population of Centaurs crossing Jupiter's orbit. Using a dynamically-validated JFC population, we find that only $\sim 20\%$ of Centaurs pass through the gateway prior to becoming JFCs, in accordance with previous studies. We show that more than half of JFC dynamical clones entering the gateway for the first time have already been JFCs -they simply avoided the gateway on their first pass into the inner solar system. By coupling a thermal evolution model to the orbital evolution of JFC dynamical clones, we find a higher than 50\% chance that the layer currently contributing to the observed activity of gateway objects has been physically and chemically altered, due to previously sustained thermal processing. We further illustrate this effect by examining dynamical clones that match the present-day orbits of 29P/Schwassmann-Wachmann 1, P/2019 LD2 (ATLAS), and P/2008 CL94 (Lemmon).

description: Machine Translation is the challenging problem for Indian languages. Every day we can see some machine translators being developed, but getting a high quality automatic translation is still a very distant dream . The correct translated sentence for Hindi language is rarely found. In this paper, we are emphasizing on English-Hindi language pair, so in order to preserve the correct MT output we present a ranking system, which employs some machine learning techniques and morphological features. In ranking no human intervention is required. We have also validated our results by comparing it with human ranking.

description: One of the common approximations in long-term evolution studies of small bodies is the use of circular orbits averaging the actual eccentric ones, facilitating the coupling of processes with very different timescales, such as the orbital changes and the thermal processing. Here we test a number of averaging schemes for elliptic orbits in the context of the long-term evolution of comets, aiming to identify the one that best reproduces the elliptic orbits' heating patterns and the surface and subsurface temperature distributions. We use a simplified thermal evolution model applied on simulated comets both on elliptic and on their equivalent averaged circular orbits, in a range of orbital parameter space relevant to the inner solar system. We find that time averaging schemes are more adequate than spatial averaging ones. Circular orbits created by means of a time average of the equilibrium temperature approximate efficiently the subsurface temperature distributions of elliptic orbits in a large area of the orbital parameter space, rendering them a powerful tool for averaging elliptic orbits.

C-C bond forming reaction

description: Carbon-carbon (C–C) bonds construct the skeleton of all organic molecules. Hence, the development of new efficient methods of C–C bond formation is of great significance in organic chemistry. Since the discovery of the Grignard reaction, carbonyl addition has been an established method for C–C bond formation. In classical carbonyl additions, premetalated reagents or stoichiometric metallic reductants are required. By taking advantage of the native reducing capability of alcohols, our lab has developed methods that exploit alcohols and π-unsaturates to generate transient electrophile-nucleophile pairs to directly convert lower alcohols to higher alcohol. Efforts have been focused on the development of transition metal-catalyzed redox-triggered coupling reactions of primary alcohols and aldehydes to π-unsaturates as well as aryl iodides. Modern methods to construct new C-C bonds in highly selective manner via carbonyl addition were undertaken.
On the Intensity Distribution Function of Blazed Reflective Diffraction Gratings

description: We derive from first principles the expression for the angular/wavelength distribution of the intensity diffracted by a blazed reflective grating, according to a scalar theory of diffraction. We considered the most common case of a groove profile with rectangular apex. Our derivation correctly identifies the geometric parameters of a blazed reflective grating that determine its diffraction efficiency, and fixes an incorrect but commonly adopted expression in the literature. We compare the predictions of this scalar theory with those resulting from a rigorous vector treatment of diffraction from one-dimensional blazed reflective gratings.

description: Markov automata combine continuous time, probabilistic transitions, and nondeterminism in a single model. They represent an important and powerful way to model a wide range of complex real-life systems. However, such models tend to be large and difficult to handle, making abstraction and abstraction refinement necessary. In this paper we present an abstraction and abstraction refinement technique for Markov automata, based on the game-based and menu-based abstraction of probabilistic automata. First experiments show that a significant reduction in size is possible using abstraction.
