title: Towards an Intelligent Debugging System for Pascal Programs: On the Theory and Algorithms of Plan Recognition in Rich's Plan Calculus
Creators: name: Lutz, Rudi
Publisher: name: The Open University
Year: 1993

description: This thesis presents work in progress on building an intelligent general purpose, domain-free debugging system for Pascal programs. This system (IDS) is based on Rich’s surface plan/plan calculus graph formalisms, and this thesis develops theory and algorithms for performing program understanding within this framework. This thesis is in three parts, the first part describes why an ability to do both plan recognition and general purpose reasoning is essential for debugging programs. The second part of this thesis describes the plan calculus and shows how it offers the ability to combine both general purpose reasoning, and (graph-based) plan recognition. It then goes on to present a new polynomial time algorithm (a generalisation of traditional chart parsing for string grammars) for doing bottom-up, or top-down, analysis of surface plans. This algorithm is presented in the framework of restricted structure sharing flow graph grammars developed for this purpose. To justify the use of such grammars this part of the thesis develops the theory of deterministic operations in the plan calculus, and also develops the theory of generalised control flow environments to justify the way control flow information is handled. The final part gives an overview of IDS, and modifies the above algorithm to cope with various parts of the plan calculus that do not exactly fit into the framework we have developed. Thus this thesis gives a complete account of how to perform plan recognition in Rich’s framework. This part of the thesis also describes the translation process from Pascal to surface plans, and presents a technique for translating plans expressed in Rich’s notation, into suitable rules for the parser to use. Finally it presents some preliminary work on exactly how a debugging system using these techniques might go about locating and fixing bugs in programs.
Quantum Capacity of Partially Corrupted Quantum Network

description: We discuss a quantum network, in which the sender has $m_0$ outgoing channels, the receiver has $m_0$ incoming channels, each channel is of capacity $d$, each intermediate node applies invertible unitary, only $m_1$ channels are corrupted, and other non-corrupted channels are noiseless. As our result, we show that the quantum capacity is not smaller than $(m_0-2m_1+1)\log d$ under the following two settings. In the first case, the unitaries on intermediate nodes are arbitrary and the corruptions on the $m_1$ channels are individual. In the second case, the unitaries on intermediate nodes are restricted to Clifford operations and the corruptions on the $m_1$ channels are adaptive, i.e., the attacker is allowed to have a quantum memory. Further, our code in the second case realizes the noiseless communication even with the single-shot setting and is constructed dependently only on the network topology and the places of the $m_1$ corrupted channels while this result holds regardless of the network topology and the places.

description: This study analyzed the determinants ofrice importation in Nigeria (1991-2015). Data were collected from secondary sources, analyzed using vector error correction model, variance decomposition and impulse response. The result ~howed that inflation rate in the previous year and population in the previous year were the variables that significantly affected the importation of rice in the long run while rice output in the previous year was the only variable that significantly affected rice importation in the short ruri. It was therefore recommended that the Federal government should put in place policies to increase and improve on the quality of locally produced rice through agricultural credit, fertilizer distribution, packaging and marketing. Also the Federal Government should set up policies that will encourage investment through appropriate financing at reasonable interest rate so that agribusiness will be promoted, particularly in the rice sub-sector.

description: The paper presents numerical simulations performed on dielectric properties of two-dimensional binary composites on eleven regular space filling tessellations. First, significant contributions of different parameters, which play an important role in the electrical properties of the composite, are introduced both for designing and analyzing material mixtures. Later, influence of structural differences and intrinsic electrical properties of constituents on the composite's over all electrical properties are investigated. The structural differences are resolved by the spectral density representation approach. The numerical technique, without any {\em a-priori} assumptions, for extracting the spectral density function is also presented.

description: The present research aimed at documenting the educational actions and programmes about climate change that have been implemented in the Prefecture of Larissa, Greece, and at investigating whether their design and implementation aligns with the principles of adult learning. It also sought to examine whether the participants of these programmes have developed environmental awareness and whether they have adapted to the new conditions created by climate change. According to the findings of this study, the climate change-related programmes implemented in the Prefecture of Larissa were mostly organized by public institutions, had a short duration and did not always include a practical or experiential part. Their primary purpose was to lead to a more comprehensive approach towards environmental issues and to contribute to the citizens’ and professionals’ adaptation to the changes that have occurred due to climate change. The process of informing, raising awareness and helping people adapt to the consequences of climate change can be achieved by properly designing and implementing programmes that meet the educational needs of the target population

description: Atom-light interactions in nano-scale systems hold great promise for novel technologies based on integrated emitters and optical modes. We present the design architecture, construction method, and characterization of an all-glass alkali-metal vapor cell with nanometer-scale internal structure. Our cell has a glue-free design which allows versatile optical access, in particular with high numerical aperture optics, and incorporates a compact integrated heating system in the form of an external deposited ITO layer. By performing spectroscopy in different illumination and detection schemes, we investigate atomic densities and velocity distributions in various nanoscopic landscapes. We apply a two-photon excitation scheme to atoms confined in one dimension within our cells, achieving resonance line-widths more than an order of magnitude smaller than the Doppler width. We also demonstrate sub-Doppler line-widths for atoms confined in two dimensions to micron-sized channels. Furthermore, we illustrate control over vapor density within our cells through nano-scale confinement alone, which could offer a scalable route towards room-temperature devices with single atoms within an interaction volume. Our design offers a robust platform for miniaturized devices that could easily be combined with integrated photonic circuits.

description: Lattice QCD solvers encounter critical slowing down for fine lattice spacings and small quark mass. Traditional matrix eigenvalue deflation is one approach to mitigating this problem. However, to improve scaling we study the effects of deflating on the coarse grid in a hierarchy of three grids for adaptive mutigrid applications of the two dimensional Schwinger model. We compare deflation at the fine and coarse levels with other non deflated methods. We find the inclusion of a partial solve on the intermediate grid allows for a low tolerance deflated solve on the coarse grid. We find very good scaling in lattice size near critical mass when we deflate at the coarse level using the GMRES-DR and GMRES-Proj algorithms.

description: Objectives: Signal transduction through the mothers against decapentaplegic (SMAD) is a family of signal transduction factors that mediate signalling of the transforming growth factor B (TGFB)-superfamily of cell regulatory proteins. A recent transcriptomic analysis of post-mortem, cortical tissue from subjects with schizophrenia found decreased mRNA expression of SMAD2 and SMAD4 in the dorsolateral prefrontal cortex (DLPFC) associated with the disorder. To expand this initial finding, we sought to determine whether SMAD2 and SMAD4 protein were also altered in the cortex from subjects with schizophrenia. Methods: Western blotting was used to measure SMAD2 and SMAD4 protein levels in DLPFC and anterior cingulate cortex (ACC) taken post-mortem from subjects with schizophrenia (n = 20) and matched control (n = 20) subjects. Results: Compared to controls, levels of SMAD4 were 25% lower in the DLPFC and 38% lower in the ACC from subjects with schizophrenia. By contrast, SMAD2 levels were not altered in either DLPFC or ACC. Conclusions: Our finding of lower SMAD4 protein in the cortex suggests there are likely to be abnormalities in cortical TGFB-superfamily signalling in schizophrenia.

description: Searches for New Physics focus either on the direct production of new particles at colliders or at deviations from known observables at low energies. In order to discover New Physics in precision measurements, both experimental and theoretical uncertainties must be under full control. Laser spectroscopy nowadays offers a tool to measure transition frequencies very precisely. For certain molecular and atomic transitions the experimental technique permits a clean study of possible deviations. Theoretical progress in recent years allows us to compare ab initio calculations with experimental data. We study the impact of a variety of New Physics scenarios on these observables and derive novel constraints on many popular generic Standard Model extensions. As a result, we find that molecular spectroscopy is not competitive with atomic spectroscopy and neutron scattering to probe new electron-nucleus and nucleus-nucleus interactions, respectively. Molecular and atomic spectroscopy give similar bounds on new electron-electron couplings, for which, however, stronger bounds can be derived from the magnetic moment of the electron. In most of the parameter space H_2 molecules give stronger constraints than T_2 or other isotopologues.

description: The flow of both solid and liquid particles, especially in mountain basins, is impulsive, not easily predictable and for this reason extremely dangerous. As to avoid the damages caused by this phenomenon, barriers are usually used. They are easy to install but are high maintenance and, in addition, they are aimed at blocking all the sediment, running the risk of under-designing the volume to be collected. Starting from this assumption, the need of a maintenance-friendly approach was investigated by Maccaferri Innovation Center with an innovative apparatus called Mini Skirt Check Dam (MSCD). This is a special dam which is made up of two parts: solid wings that have a vertical fissure in which a ring net is applied. The net is uplifted from the ground as to leave a part of the debris flowing and blocking only the top part of it. The research analyzed the design procedure of a standard weir and several laboratory tests were performed in cooperation with the University of Trento (Italy) that ended with the creation of a new approach against debris flow. The MSCD permits the cutting of the peak of the flow rate and, at the same time, blocking tree trunks and boulders. Laboratory tests conducted showed that the combination of weir and net slows down the debris and collects only the most dangerous part of the flow with a lower maintenance requirement and a good hydraulic performance.

The first part of the report outlines programs of TROLL commands which carry out tasks necessary to model development and operation. The second part of the report documents ways of creating sets of these TROLL commands using the mainframe or micro computer. To the extent that GOL component models have standard functional forms across commodities and countries, these groups of TROLL commands and parent programs greatly simplify GOL model management.
The transverse nucleon single-spin asymmetry for the semi-inclusive production of photons in lepton-nucleon scattering

description: We study the semi-inclusive production of real, high-$p_T$, isolated photons in unpolarized and polarized lepton-proton collisions, $\ell p\to \ellγX$. In particular we analyze the transverse nucleon single-spin asymmetry within the collinear twist-3 formalism in perturbative QCD to leading order (LO) accuracy. We find that this spin asymmetry is generated by twist-3 dynamical quark-gluon-quark ($qgq$) correlations in the nucleon through the so-called soft-fermion and hard pole contributions. Hence, this process unprecedentedly allows for a point-by-point scan of the support of the dynamical $qgq$ twist-3 matrix elements $F_{FT}(x,x^\prime)$ and $G_{FT}(x,x^\prime)$ in lepton-nucleon scattering experiments.

The observed region was centered roughly on the cluster core and covered 644 arcmin^2. The cluster was monitored on 59 nights in 1999 and 2000. A total of 117 new variables were identified. Among them there are 16 RR Lyr-type stars, 35 SX Phe variables and 26 eclipsing binaries. A comprehensive catalog including all variable stars so far reported from the cluster field is presented. We list basic photometric properties and provide finding charts for a total of 392 objects. For 313 of them new BV light curves were obtained. The presented sample includes several interesting variables, such as SX Phe stars with extremely short periods of pulsation and several candidates for pulsating K giants. Optical counterparts to 9 X-ray sources detected by XMM and Chandra telescopes were identified: all of them are likely to be foreground variables not related to the cluster.

description: Income distribution analysis can be conducted from the point of view of the comparisons between different geographical regions, family types or socio-economic groups it can also be carried out to assess the effects of an economic policy over time. The paper presents the results of a research on income distribution of Polish farmers which allowed us to formulate several conclusions concerning the differentiation of income inequality, poverty and wealth for the households of farmers in different macro-regions. The analysis uses the Gini inequality index and selected poverty and wealth indicators. The basis for the calculations was micro data coming from the Household Budget Survey conducted by the Central Statistical Office of Poland for 2015. The results of the research showed that the highest income inequality among the farmers’ households was observed in the northern region. Also this region was characterised by the highest percentage of households considered affluent. But the lowest Gini inequality coefficient was observed for the south-western region, where there were no farmers’ households exceeding the richness threshold.

This is attributed to substantial antiferromagnetic exchange interaction between different monomers. The intermolecular exchange interaction, electronic structure and magnetic properties of this molecular magnet are calculated using density-functional theory within generalized-gradient approximation. Calculations are in good agreement with experiment.

description: The present doctoral thesis aims to highlight the sacred element in the life and works of the Dutch post-impressionist painter Vincent Willem van Gogh (1853-1890), in the artist's dialectical relationship with the religious element and God. It examines the artist's relationship to Protestantism and Calvinism, his family background, how he experienced his religious sentiment and how he identified himself as an artist, as well as what symbols he used in his art to render the divine. Techniques and terms used by Van Gogh in his works are also examined and they are chosen with topics of Orthodox Theology. In addition, the present research highlights social extensions of the works of the Dutch painter as well as his written legacy.

description: In several years leading up to and in the year of the accession, Polish agriculture has seen a rapid growth in the agricultural production efficiency, followed by its slow decline. The article identifies the reasons for this phenomenon. In the first of these subperiods, there was considerable economic freedom and an increase in support for farms, granted mainly by the domestic funds. In the years after 2004, the situation changed. The amounts of aid funds increased, so did the environmental and consumer health and animal welfare requirements to be met by farmers being beneficiaries of subsidies. In addition, larger farms also reduced their economic activity due to the degression in subsidy rates. It is also probable that some agricultural producers have been mainly focused on using subsidies and this phenomenon was accompanied by a decrease in interest in improving the agricultural production efficiency.

description: The equilibrium distributions of the different pasta geometries and their linear sizes are calculated from the mean field Gibbs energy functional in symmetric nuclear matter at finite temperature. The average sizes and shapes coincide approximately with the ones predicted by a standard pasta calculation in the coexisting phase approximation, but fluctuations are additionally calculated and seen to increase with temperature and baryonic density. The different pasta shapes are shown to coexist in a wide domain of density and temperature, in qualitative agreement with the findings of large scale molecular dynamics simulations, but with a much less expensive computational cost.

description: Superconducting flux qubits are a promising candidate for solid-state quantum computation. One of the reasons is that implementing a controlled coupling between the qubits appears to be relatively easy, if one uses tunable Josephson junctions. We evaluate possible coupling strengths and show, how much extra decoherence is induced by the subgap conductance of a tunable junction. In the light of these results, we evaluate several options of using intrinsically shunted junctions and show that based on available technology, Josephson field effect transistors and high-Tc junctions used as pi-shifters would be a good option, whereas the use of magnetic junctions as pi-shifters severely limits quantum coherence.

description: There are several unexplored regions of the short-duration radio transient phase space. One such unexplored region is the luminosity gap between giant pulses (from pulsars) and cosmologically located fast radio bursts (FRBs). The Survey for Transient Astronomical Radio Emission 2 (STARE2) is a search for such transients out to 7 Mpc. STARE2 has a field of view of 3.6 steradians and is sensitive to one-millisecond transients above $\sim300$ kJy. With a two-station system we have detected and localized a solar burst, demonstrating that the pilot system is capable of detecting short duration radio transients. We found no convincing transients with duration between 65 $μ$s and 34 ms in 200 days of observing, limiting with 95% confidence the all-sky rate of transients above $\sim300$ kJy to $< 40$ ${\rm sky^{-1} year^{-1}}$. If the luminosity function of FRBs could be extrapolated down to 300 kJy for a distance of 10 kpc, then one would expect the rate to be $\sim2$ ${\rm sky^{-1} year^{-1}}$.

Modelling the variability of the Fe K alpha line in accreting black holes

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The variability of the Fe K alpha line near 6.5 keV seems to be reduced compared to the variability of the hard X-rays which presumably drive the line emission. This is observed both in active galactic nuclei and galactic black hole binaries. We point out that such reduced variability, as well as lack of coherence between the variations of the line and the continuum, are a natural prediction of a propagation model of variability in the geometry of inner hot accretion flow. We compute detail model predictions of the variability characteristics which could be compared with current and future data. We also point out that the model requires a gradual disappearance of the cold disc, rather than a sharp transition from the cold disc to a hot flow.

description: We present ALMA observations of a merging system at z ~ 4.57, observed as a part of the ALMA Large Program to INvestigate [CII] at Early times (ALPINE) survey. Combining ALMA [CII] 158 micron and far-infrared continuum data with multi-wavelength ancillary data we find that the system is composed of two massive (Mstar >~ 10^10 Msun) star-forming galaxies experiencing a major merger (stellar mass ratio r_mass ~ 0.9) at close spatial (~13 kpc; projected) and velocity (delta_v < 300 km/s) separations, and two additional faint narrow [CII]-emitting satellites. The overall system belongs to a larger-scale protocluster environment and is coincident to one of its overdensity peaks. ALMA reveals also the presence of [CII] emission arising from a circumgalactic gas structure, extending up to a diameter-scale of ~30 kpc. Our morpho-spectral decomposition analysis shows that about 50% of the total flux resides between the individual galaxy components, in a metal-enriched gaseous envelope characterized by a disturbed morphology and complex kinematics. Similarly to observations of shock-excited [CII] emitted from tidal tails in local groups, our results can be interpreted as a possible signature of interstellar gas stripped by strong gravitational interactions, with a possible contribution from material ejected by galactic outflows and emission triggered by star formation in small faint satellites. Our findings suggest that mergers could be an efficient mechanism of gas mixing in the circumgalactic medium around high-z galaxies, and thus play a key role in the galaxy baryon cycle at early epochs.

description: The article compares the European Union (EU) candidate countries (CC) and the Eastern Partnership countries (EPC) in terms of their self-sufficiency in basic food products by analysing the average consumption of these products between 1992 and 2013. The countries were grouped according to their self-sufficiency ratios by Ward’s method of cluster analysis. Studies have shown that in the first group of countries in 1992-1999 and 2000-2013 there were primarily Albania, Armenia, Bosnia and Herzegovina, Georgia and Macedonia, and they had the lowest self-sufficiency ratios for most products compared to the second and the third group of countries. In both periods, in the second group there were Azerbaijan and Turkey, which have the highest self-sufficiency ratio for fruit, and in the third group there were mainly Belarus, Moldova, Serbia and Ukraine. These countries were characterised by surplus in the production of most foods. Research showed that in the second period under consideration, Montenegro moved to a group of countries with a lower level of self-sufficiency. Studies proved that during the period under investigation the increase in the self-sufficiency of these countries resulted from greater production, lesser loss during production and lower consumption of the products under analysis.

description: We give a systematic study of ${\bf B}_c\to {\bf B}_n V$ decays, where ${\bf B}_c$ and $ {\bf B}_n$ correspond to the anti-triplet charmed and octet baryons, respectively, while $V$ stand for the vector mesons. We calculate the color-symmetric contributions to the decays from the effective Hamiltonian with the factorization approach and extract the anti-symmetric ones based on the experimental measurements and $SU(3)_F$ flavor symmetry. We find that most of the existing experimental data for ${\bf B}_c\to {\bf B}_n V$ are consistent with our fitting results. We present all the branching ratios of the Cabbibo allowed, singly Cabbibo suppressed and doubly Cabbibo suppressed decays of ${\bf B}_c\to {\bf B}_n V$. The decay parameters for the daughter baryons and mesons in ${\bf B}_c\to {\bf B}_n V$ are also evaluated. In particular, we point out that the Cabbibo allowed decays of $Λ_c^+ \to Λ^0 ρ^+$ and $ Ξ_c^0 \to Ξ^- ρ^+$ as well as the singly Cabbibo suppressed ones of $Λ_c^+ \to Λ^0 K^{*+}$, $Ξ_c^+ \to Σ^+ ϕ$ and $Ξ_c^0\to Ξ^- K^{*+}$ have large branching ratios and decay parameters with small uncertainties, which can be tested by the experimental searches at the charm facilities.

description: Low bone mineral density (BMD) is believed to influence the outcome of instrumented spinal surgery and can lead to reoperation. Purpose of this observational and case-control study was to investigate the association of BMD with the risk of reoperation following instrumented lumbar spinal fusion (LSF). For the observational study, 81 patients were included who received LSF with and without augmentation. For the case-control study, 18 patients who had reoperation following LSF were matched to 26 patients who did not have reoperation (matched by sex, age +/- 5 years, fused levels and PMMA-augmentation). Opportunistic BMD screening was performed in perioperative CT scans using asynchronous calibration. Mean BMD was compared between patients with and without reoperation in augmented and non-augmented surgeries. In the observational study, prevalence of osteoporosis (BMD < 80 mg/cc) was 29% in non-augmented and 85% in augmented LSF. Seven of 48 patients with non-augmented (15%) and 4 of 33 patients with augmented LSF (12%) had reoperation. In non-augmented LSF, patients with reoperation had significantly lower BMD than patients without reoperation (P = 0.005). The best cut-off to predict reoperation after non-augmented LSF was BMD < 83.7 mg/cc. In the case-control study, patients with reoperation presented numerically lower BMD of 78.8 +/- 33.1 mg/cc than patients without reoperation with BMD of 89.4 +/- 39.7 mg/cc (P = 0.357). Despite much lower BMD surgeries with PMMA-augmentation showed no higher reoperation rate compared to non-augmented surgeries. Patients with reoperation following LSF showed slightly lower BMD compared to matched patients without reoperation, but the difference was not statistically significant. Opportunistic BMD screening can be performed in preoperative CT, thus informing about osteoporotic bone, a potential risk factor of surgery failure.
