Extending Graph Query Languages by Reduction
Creators: name: Weinell, Erhard

description: Graph grammars are a well-founded technology for visually specifying computations or the processing of complex data structures. Up to now, numerous languages and tools for graph transformations exist, whilst new ones are proposed regularly. However, these tools have no technical basis such as an execution framework or data storage in common. Instead, graph transformation machineries are usually implemented anew each time. The DRAGOS graph database is especially well-suited for building graph transformation systems, as it is able to store complex graph structures directly. Besides its storage functionality, the database also provides a Query & Transformation Mechanism which is able to handle complex queries upon the stored graphs, and to modify them accordingly. Being designed as a basis for graph and model transformation tools, this mechanism is required to allow a flexible adaptation and extension according to the respective applications' needs. The present paper discusses how this requirement is covered by the proposed Query &  Transformation Mechanism.

description: From previous ground-based observations, the hot Jupiter exoplanet XO-6b was reported to exhibit apparently periodic transit timing variations (TTVs), with a semi-amplitude of 14 minutes and a period of about 450 days. These variations were interpreted as being due to a resonant perturbation between XO-6b and a hitherto unknown low-mass planet orbiting the same star. To understand this enigmatic planetary system better, we analysed three sectors of data, spanning over seven months, from the Transiting Exoplanet Survey Satellite (TESS), which produces high-quality light curves that are well suited to characterizing exoplanets and searching for TTVs. Here we present an updated orbital period of 3.7649893 $\pm$ 0.0000037 days and a transit epoch of 2456652.7157 $\pm$ 0.0022 BJD$_{TDB}$. The planetary parameters we report, while consistent with their discovery values, have greatly improved precision. Notably, we find no evidence for TTVs: we can rule out TTVs $\gtrsim$ 2.5 minutes at the 3$σ$ level. Therefore, the TESS data have sufficient precision and time baseline to reveal readily the previously reported TTVs of approximately 10 minutes. Our findings highlight TESS's capabilities for robust follow-up, and confirm that TTVs are rarely seen in hot Jupiters, unlike is the case with small planets.

description: This paper describes an approach for reusing specification patterns. Specification patterns are design patterns that are expressed in a formal specification language. Reusing a specification pattern means instantiating it or composing it with other specification patterns. Three levels of composition are defined: juxtaposition, composition with inter-patterns links and unification. This paper shows through examples how to define specification patterns in B, how to reuse them directly in B, and also how to reuse the proofs associated with specification patterns.

description: The mechanical properties of Mg-4wt.% Zn alloy single crystals along the [0001] orientation were measured through micropillar compression at 23C and 100C. Basal slip was dominant in the solution treated alloy, while pyramidal slip occurred in the precipitation hardened alloy. Pyramidal dislocations pass the precipitates by forming Orowan loops, leading to homogeneous deformation and to a strong hardening. The predictions of the yield stress based on the Orowan model were in reasonable agreement with the experimental data. The presence of rod-shape precipitates perpendicular to the basal plane leads to a strong reduction in the plastic anisotropy of Mg.

description: The estimation of the density matrix of a $k$-level quantum system is studied when the parametrization is given by the real and imaginary part of the entries and they are estimated by independent measurements. It is established that the properties of the estimation procedure depend very much on the invertibility of the true state. In particular, in case of a pure state the estimation is less efficient. Moreover, several estimation schemes are compared for the unknown state of a qubit when one copy is measured at a time. It is shown that the average mean quadratic error matrix is the smallest if the applied observables are complementary. The results are illustrated by computer simulations.

Supernovae and Cosmology

description: The extreme luminosity and their fairly unique temporal behaviour have made supernovae a superb tool to measure distances in the universe. As complex astrophysical events they provide interesting insights into explosion physics, explosive nucleosynthesis, hydrodynamics of the explosion and radiation transport. They are an end product of stellar evolution and provide clues to the stellar composition. Since they can be observed at large distances they have become critical probes to further explore astrophysical effects, like dust properties in external galaxies and the star formation history of galaxies. Some of the astrophysics interferes with the cosmological applications of supernovae. The local velocity field, distorted by the gravitational attraction of the local large scale structure, and the reddening law appear at the moment the major limitations in the accuracy with which cosmological parameters can be determined. These absorption effects can introduce a secondary bias into the observations of the distant supernovae, which needs to be carefully evaluated. Supernovae have been used for the measurement of the Hubble constant, i.e. the current expansion rate of the universe, and the accelerated cosmic expansion directly inferred from the apparent faintness of the distant supernovae.

description: Herein, we investigate the symmetry-protected toroidal dipole resonances and conditions of their excitation in a new type of electromagnetic metamaterials. These metamaterials are all-dielectric planar periodic arrays of dielectric disks disposed on a dielectric substrate. The elementary building blocks of the array are trimers which are distributed in hexagonal unit supercells. The highest geometrical symmetry of the unit supercell is C6v. The analysis is fulfilled by using the representation theory of groups with the application of the magnetic group theory, which is a new approach in solving such problems. We have shown that to get access to the toroidal supermodes of the array, the unit supercell symmetry must be broken twice: firstly, the C3v symmetry of the trimer, and secondly, the C6v symmetry of the unit supercell needs to be reduced. Selection rules for the symmetric and antisymmetric orders of the toroidal dipole moments in the arrays are defined. In particular, we have shown that with the reduction of the unit supercell symmetry to the C2v group, the array exhibits the toroidal dipole resonance with an antitoroidic order. The arrays with the lower Cs symmetry can provide the resonances with both toroidic and antitoroidic orders. It is also shown that these arrays are always polarization sensitive. Full-wave simulations and experiments confirm the theoretical predictions. The suggested metamaterials can provide an enhanced light-matter interaction due to the spatially and temporally confined light in resonant systems with very high quality factors.

description: The special surface transition at (2+1)-dimensional quantum critical point is precluded in corresponding classical critical point. The mechanism of such behavior which is only found in dimerized Heisenberg models so far is still under debate. To illuminate the role of symmetry protected topological (SPT) phase in inducing such nonordinary behaviors, we study a system on a two-dimensional square lattice consisted by interacting spin-1 Haldane chains, which has a genuine SPT phase--the Haldane phase--at weak interchain interactions and a quantum critical point belonging to the classical 3D O(3) universality class to the Néel phase. Different from models studied previously, there is no dimerization in the current model. Cutting the system along the chain direction or perpendicular to the chain direction exposes two different surfaces. Using unbiased quantum Monte Carlo simulations, we find that the two different types of surface show completely different surface critical behaviors at the bulk critical point, resulted from different surface states in the SPT phase. For the system with surfaces along the chain direction, the surface critical behavior is of ordinary type of the bulk 3D O(3) critical point, while for the surfaces perpendicular to the chain direction, the surface critical behavior is nonordinary, consistent with special transitions found in dimerized Heisenberg models. Our numerical results demonstrate that the gapless surface state in the gapped SPT phase together with the gapless mode of critical point is a pure quantum scenario that leads to the nonordinary transition.

description: Crash data in Kentucky show that the fatal crash rate on two-lane rural roads is substantially higher than on any other type of road. Improvements have been proposed at some locations on this type of road which involve either upgrading the existing two-lane road or adding lanes resulting in a four-lane road. As part of the public information process, highway officials have been asked to document the previous results of this type of construction. The objectives of this study were to: 1) identify sections of two-lane rural roadways where either the two-lane road had been realigned and reconstructed or additional lanes had been added and 2) conduct a before- and-after analysis to determine how these changes affected traffic crashes.  Of the 49 locations included in the study, 25 involved adding lanes and converting to a four-lane road while the two-lane road was upgraded (realignment with wider lanes and shoulders) at 24 locations. Before the construction, the average traffic volume was almost three times higher on the roads where additional lanes were added than where the two-lane road was upgraded. The average daily traffic increased dramatically after the construction was completed with a slightly higher increase for roads where lanes were added.  When all the locations are considered, there was a 51 percent reduction in the crash rate when the road was upgraded and a 56 percent reduction in the crash rate when lanes were added. The rate was reduced from 250 to 122 crashes/100 million vehicle miles (MVM) when the road was upgraded and from 258 to 114 crashes/100 MVM when lanes were added. When only the number of crashes is considered, the number of crashes per mile decreased by 39 percent when the road was upgraded and by 45 percent when lanes were added. The rate of injury or fatal crashes was reduced by 54 percent for upgrading the road and 55 percent by adding lanes while the number of crashes per mile decreased by 43 percent both when the road was upgraded and when lanes were added.  The overall conclusion of the study is that both upgrading two-lane rural roads and converting the road to four lanes are effective methods of reducing total crashes and injury or fatal crashes. The traffic volume would determine the appropriate alternative.

description: Optical frequency division (OFD) via optical frequency combs (OFC) has enabled a leap in microwave metrology leading to noise performance never explored before. Extending the method to millimeter-wave (mmW) and terahertz (THz)-wave domain is of great interest. Dissipative Kerr solitons (DKSs) in integrated photonic chips offer a unique feature of delivering OFCs with ultrahigh repetition rates from 10 GHz to 1 THz making them relevant gears to perform OFD in the mmW and THz-wave domain. We experimentally demonstrate OFD of an optically-carried 3.6 THz reference down to 300 GHz through a DKS, photodetected with an ultrafast uni-traveling-carrier photodiode (UTC-PD). A new measurement system, based on the characterization of a microwave reference phase-locked to the 300 GHz signal under test, yields attosecond-level timing noise sensitivity, leveraging conventional technical limitations. This work places DKSs as a leading technology in the mmW and THz-wave field promising breakthroughs in fundamental and civilian applications.

Female rivalry at work: Case of Moroccan executives in the industrial sector

Year: 2024

description: As part of a doctoral research on professional equality between women and men, we carried out a qualitative study with the aim of making Moroccan female executives talk about their working conditions in the private industrial environment. The question of interpersonal relationships at work was thus addressed; the eighteen women interviewed were invited to reveal their preference as to the gender of their superiors, colleagues and collaborators. The results were surprising: the majority (67%) of respondents say they prefer to work with and for men and only 16% of respondents support their female peers.

Given the sexism that characterizes the workplace, especially the industrial one, this result seems to be illogical since we expect female solidarity to face gender discrimination at work.

At work, is the woman really the enemy of the woman? How conflicts between women manifest themselves? What are the causes? How can we limit female rivalry at work? It is to these questions that we will try to answer throughout this article.

description: We present three-dimensional, nonrelativistic, hydrodynamic simulations of bow shocks in pulsar wind nebulae. The simulations are performed for a range of initial and boundary conditions to quantify the degree of asymmetry produced by latitudinal variations in the momentum flux of the pulsar wind, radiative cooling in the postshock flow, and density gradients in the interstellar medium (ISM). We find that the bow shock is stable even when travelling through a strong ISM gradient. We demonstrate how the shape of the bow shock changes when the pulsar encounters density variations in the ISM. We show that a density wall can account for the peculiar bow shock shapes of the nebulae around PSR J2124-3358 and PSR B0740-28. A wall produces kinks in the shock, whereas a smooth ISM density gradient tilts the shock. We conclude that the anisotropy of the wind momentum flux alone cannot explain the observed bow shock morphologies but it is instead necessary to take into account external effects. We show that the analytic (single layer, thin shell) solution is a good approximation when the momentum flux is anisotropic, fails for a steep ISM density gradient, and ap- proaches the numerical solution for efficient cooling. We provide analytic expressions for the latitudinal dependence of a vacuum-dipole wind and the associated shock shape, and compare the results to a split-monopole wind. We find that we are unable to distinguish between these two wind models purely from the bow shock morphology.

description: Quantum key distribution (QKD) is the first quantum information task to reach the level of mature technology, already fit for commercialization. It aims at the creation of a secret key between authorized partners connected by a quantum channel and a classical authenticated channel. The security of the key can in principle be guaranteed without putting any restriction on the eavesdropper's power. The first two sections provide a concise up-to-date review of QKD, biased toward the practical side. The rest of the paper presents the essential theoretical tools that have been developed to assess the security of the main experimental platforms (discrete variables, continuous variables and distributed-phase-reference protocols).

description: The objective of this report was to document the results of the Click It or Ticket campaign in Kentucky. The campaign involved a combination of earned media, paid media, and enforcement. The earned media started about three weeks prior to Memorial Day 2001 and continued through the enforcement period. The paid media started about two weeks prior to Memorial Day. The enforcement period was a two-week period including the week before and the week of Memorial Day.  The evaluation of the campaign included documenting the activities associated with the program (publicity and enforcement) and evaluating the results. The evaluation involved conducting observations of seat belt usage at a sample of locations across the state, motorist surveys obtained at driver licensing locations, telephone surveys of drivers, and comparing the number of fatal and injury crashes during the enforcement period with previous years.  Seat belt usage at a mini-sample set of 21 locations across the state found that usage increased from a baseline level of 60 percent to a high of 70 percent during the enforcement phase of the campaign. No difference in usage rates could be associated with only the media portion of the campaign.  Results of the surveys of drivers found that the publicity was effective in making drivers aware of the increase in enforcement and checkpoints associated with the campaign. The post- campaign telephone survey showed a significant increase in drivers who stated they had recently increased their use of seat belts with the cause of the increase related to the seat belt law and not wanting to receive a ticket. The telephone survey showed that about two-thirds of the drivers had heard of the Click It or Ticket campaign.  The extent of the publicity was documented. The effectiveness of the television and radio spots was confirmed with the driver surveys which showed that their knowledge about the campaign was most often from television or radio.  Enforcement was conducted by both state and local police through saturated enforcement and checkpoints. A total of 5,806 seat belt citations and 691 child restraint citations were given during the two-week enforcement period.  The numbers of fatal crashes, fatalities, injury crashes, and injuries during the two-week enforcement period of the campaign were lower than in any of the previous five years. The number of fatalities during this period was 7 less than the average of the previous five years with 253 fewer injuries.  A review of the data results in the opinion that the current law in Kentucky must be changed from secondary to primary enforcement to obtain a long-term high seat belt use percentage. There must also be an awareness by the public that the law is being enforced.

description: The first direct experimental observation of an electric quadrupole ($\textit{E}$2) transition between bound states of an atomic negative ion has been made. The transition was observed in the negative ion of bismuth by resonant (1+1) photodetachment from Bi$^-$ $^3\textit{P}_2$ via excitation of the Bi$^-$ $^3\textit{P}_0$ fine structure state. The $\textit{E}$2 transition properties were independently calculated using a hybrid theoretical approach to account for the strong multi-level electron interactions and relativistic effects. The experimental and theoretical results are in excellent agreement, providing valuable new insights into this complex system and forbidden transitions in negative ions.

2001 Safety Belt Usage Survey in Kentucky

description: The objective of this study was to establish 2001 safety belt and child safety seat usage rates in Kentucky. The 2001 survey continues to document the results after enactment of a statewide mandatory safety belt law in 1994. It also documented the long term results of the Click It or Ticket enforcement campaign which was conducted around Memorial Day. Data were collected at 200 randomly selected sites spread across Kentucky. Data from the individual sites were combined into a statewide percentage considering function classification, geographic region, and vehicle miles traveled.  The data show that the usage rate increase found in 1999, after a few years where the rate had remained at a stable level, continued in 2001. The usage rate for front seat occupants was 62 percent in 2001, compared to 60 percent in 2000, 59 percent in 1999, 54 percent in 1998, 1997 and 1995, 55 percent in 1996, and 58 percent in 1994. The current usage is substantially above the 1993 level, prior to enactment of the statewide law, of 42 percent. The usage rate at a mini-sample of 21 locations was 63 percent compared to a high of 70 percent which was found during the enforcement period of the Click It or Ticket campaign.  The 2001 statewide usage rate for children under the age of four was determined to be 89 percent. This continues the high rate found for this age category and equals the previous high of 89 percent in 1999.  The statewide law, except for children, involves secondary enforcement. The higher rate for children could partially be related to primary enforcement. To obtain the maximum possible increase in usage, the current law should be modified to allow primary, rather than secondary, enforcement for all vehicle occupants. The potential increase which can result from an emphasis on enforcement was shown by the results of the Click It or Ticket campaign. As a minimum, primary enforcement should apply to drivers while they are in the permit and intermediate phase of the graduated license program.

description: We report on the recently proposed joint resolution of two long-standing puzzles in weak radiative (WR) and nonleptonic (NL) hyperon decays (HD). First, a good VMD-based description of WRHD is presented. In particular, the large negative asymmetry observed in the Σ^+ \to p γdecay is explained through a calculably large SU(3)-breaking effect in the relevant parity-violating amplitude. Second, the achieved description of the parity-violating WRHD amplitudes permits the extraction, via the SU(2)_W + VMD route, of the non-soft-pion correction term in the parity-violating NLHD amplitudes. The latter subtracts a substantial amount from the current-algebra commutator term, thus leading to the resolution of the old S:P discrepancy in NLHD.

description: I-65 project in downtown Louisville consisted of 27 bridges having approximately 1,493,100 ft2 of steel. The structures had existing coatings that contained lead. The project posed significant operational and public safety and operational constraints due to close proximity of the structures with residences and businesses along the entire route. In 2000, the Central Office Project Design Team developed experimental specifications to abrasive blast and re-paint the bridges. Surface preparation procedures included solvent cleaning, pack rust removal and abrasive blast cleaning. Containment enclosures were employed throughout the project, air monitoring was performed to assure satisfactory containment, and hazardous wastes were collected and disposed of. The I-65 bridges were painted with an organic zinc rich primer and a coat of tinted moisture cure aluminum polyurethane intermediate coat and an acrylic polyurethane finish coat. The project was let at a cost of about $9.30/ft2. The painting project started in April, 2001 and was successfully completed in November, 2001.
Geometric phase and chiral anomaly; their basic differences

description: All the geometric phases are shown to be topologically trivial by using the second quantized formulation. The exact hidden local symmetry in the Schrödinger equation, which was hitherto unrecognized, controls the holonomy associated with both of the adiabatic and non-adiabatic geometric phases. The second quantized formulation is located in between the first quantized formulation and the field theory, and thus it is convenient to compare the geometric phase with the chiral anomaly in field theory. It is shown that these two notions are completely different.

Investigation of CDC2-independent mitotic protein kinases
Creators: name: Gowdy, Patrick Michael
Publisher: name: University of British Columbia
Year: 2009

description: Mitosis is a highly coordinated event which ensures the equal segregation of the cytoplasmic and genetic material into two daughter cells. A key regulatory process in ensuring the temporal fidelity of mitosis involves reversible protein phosphorylation mediated by protein kinases and phosphatases. The major known protein kinase required for triggering mitosis is the cyclindependent kinase, Cdc2. Recent evidence suggests that Cdc2-independent protein kinase signaling pathways are also involved in mitosis. The murine mammary tumour cell line, FT210, has a temperature-sensitive mutation in the cdc2 gene that causes cell cycle arrest in late G2 at the non-permissive temperature. This arrest can be overcome, and mitotic events induced, by protein phosphatase inhibitors. This experimental system allows distinction between Cdc2-independent and -dependent pathways at mitosis. This allows for identification and investigation of the roles of protein kinases in Cdc2-independent mitotic pathways. I have used an in-gel protein kinase renaturation assay to identify two kinases that are activated independently of Cdc2 at mitosis: a novel 45 kDa mitotic protein kinase and a cell cycle-regulated novel 60 kDa histone-specific mitotic kinase. The 45 kDa protein kinase, p45, was active only at mitosis. p45 kinase activity was detected in all cell lines tested suggesting an essential role in cell division. The p45 kinase was determined to be unrelated to the known 46 kDa kinases, JNK1 and MAPKAP kinase-2. The histone kinase was also active only at mitosis. The identification of this histone-specific mitotic kinase confirms the existence of Cdc2-independent pathways for chromosome condensation at mitosis. I also investigated the regulation of the mitotic kinase, polo-like kinase-1 (Plk1), in Cdc2 mutant cells. Plk1 was inactive at the non-permissive temperature and therefore requires Cdc2-dependent signaling pathways for activity. Plk1 is involved in regulating chromosome segregation during mitosis. These results further strengthen the role of Cdc2 in the regulation of mitotic microtubule dynamics.

description: The PPP/BOT is a product of institutional arrangement. Institutional arrangement related to the effort increase the coverage of piping water systems that challenged by the socio-technical complexity of drinking water provision system. The Institutional Development Framework provide the opportunities to learn how the institution capable of providing the pre-condition of the actor interact at the preparation level. In the first case, for five years of the operation from January 2013 to December 2017, an improvement of the coverage is far from satisfied. Departing from 7.33%, the coverage increases reach 14.35% below the contractual target of 31.52%. In contrast, the second case operates from January 2008 - December 2017, the coverage departed from 0% and increased during the first four years to 66% beyond the contractual target of 43%. While the third case, operation January 1998 - December 2017, departed from 32.69% coverage and only reached 61% of the target of 95% after 20 years. As a result, the three cases confirmed that there could be vast differences between rules in form and rules is use or the quality of preparation affect the financial and system performances. The more compliance of the collective choice to the constitutional rules that comply with the International Best Practice showed the better the performances of the PPP/BOT proved to be.

description: Observations of low-mass companions for which the dynamical masses are well constrained help to improve the calibration of evolutionary models. Such observations thereby provide more confidence in the estimation of the mass of a companion using the photometric methods expected for the next generation of planet finder instruments. The commissioning of a new coronagraph at the Very Large Telescope (VLT) was the occasion to test the performance of this technique on the well-known object AB Dor A and its 0.09$M_\odot$ companion AB Dor C. The purpose of this paper is to refine the photometric analysis on this object and to provide an accurate photometric error budget. In addition to coronagraphy, we calibrated the residual stellar halo with a reference star. We used standard techniques for photometric extraction. The companion AB Dor C is easily detected at 0.185" from the primary star, and its magnitudes in H and Ks are in agreement with an M5.5 object, as already known from spectroscopic observations. However, these new measurements make the earlier J-band photometry less reliable. Finally, the comparison with evolutionary models supports an age of (75\pm 25) Myr, contrary to previous analyses. These observations demonstrate that coronagraphic observations can be more efficient than direct imaging, not only to improve contrast, but also to provide a better photometric estimation as long as a good calibration of the stellar halo is achieved.

description: Mathematical and computational models can assist in gaining an understanding of cell behavior at many levels of organization. Here, we review models in the literature that focus on eukaryotic cell motility at 3 size scales: intracellular signaling that regulates cell shape and movement, single cell motility, and collective cell behavior from a few cells to tissues. We survey recent literature to summarize distinct computational methods (phase-field, polygonal, Cellular Potts, and spherical cells). We discuss models that bridge between levels of organization, and describe levels of detail, both biochemical and geometric, included in the models. We also highlight links between models and experiments. We find that models that span the 3 levels are still in the minority.

description: S-stars in the Galactic Center are excellent testbeds of various general relativistic effects. While previous works focus on modeling their orbital motion around Sgr A*--the supermassive black hole in the Galactic Center--here we explore the possibility of using the rotation of S-stars to test the de Sitter precession predicted by general relativity. We show that by reorienting the rotation axes of S-stars, de Sitter precession will change the apparent width of the absorption lines in the stellar spectra. Our numerical simulations suggest that the newly discovered S4714 and S62 are best suited for such a test because of their small pericenter distances relative to Sgr A*. Depending on the initial inclination of the star, the line width would vary by as much as $20-76\,{\rm km\,s^{-1}}$ within a period of $20-40$ years. Such a variation is comparable to the current detection limit. Since the precession rate is sensitive to the orbital eccentricity and stellar quadrupole structure, monitoring the rotation of S-stars could also help us better constrain the orbital elements of the S-stars and their internal structures.

description: We suggest a general spectral method for calculating statistics of multi-step birth-death processes and chemical reactions of the type mA->nA (m and n are positive integers) which possess an absorbing state. The method yields accurate results for the extinction statistics, and for the quasi-stationary probability distribution, including large deviations, of the metastable state. The power of the method is demonstrated on the example of binary annihilation and triple branching 2A->0 and A->3A, representative of the rather general class of dissociation-recombination reactions.
