description: We investigate solitary states in a two-layer multiplex network of FitzHugh-Nagumo neurons in the oscillatory regime. We demonstrate how solitary states can be induced in a multiplex network consisting of two non-identical layers. More specifically, we show that these patterns can be introduced via weak multiplexing into a network that is fully synchronized in isolation. We show that this result is robust under variations of the inter-layer coupling strength and largely independent of the choice of initial conditions. Moreover, we study the vulnerability of solitary states with respect to changes in the inter-layer topology. In more detail, we remove links that connect two solitary nodes of each layer and evaluate the resulting pattern. We find a highly non-trivial dependence of the survivability of the solitary states on topological (position in the network) and dynamical (phase of the oscillation) characteristics.

description: Protoplanetary disks with large inner dust cavities are thought to host massive planetary or substellar companions. These disks show asymmetries and rings in the millimeter continuum, caused by dust trapping in pressure bumps, and potentially vortices or horseshoes. The origin of the asymmetries and their diversity remains unclear. We present a comprehensive study of 16 disks for which the gas surface density profile has been constrained by CO isotopologue data. We compare the azimuthal extents of the dust continuum profiles with the local gas surface density in each disk, and find that the asymmetries correspond to higher Stokes numbers or low gas surface density. We discuss which asymmetric structures can be explained by a horseshoe, a vortex or spiral density waves. Second, we reassess the gas gap radii from the $^{13}$CO maps, which are about a factor 2 smaller than the dust ring radii, suggesting that companions in these disks are in the brown dwarf mass regime ($\sim 15-50 M_{\rm Jup}$) or in the Super-Jovian mass regime ($\sim 3-15 M_{\rm Jup}$) on eccentric orbits. This is consistent with the estimates from contrast curves on companion mass limits. These curves rule out (sub)stellar companions ($q>$0.05) for the majority of the sample at the gap location, but it remains possible at even smaller radii. Third, we find that spiral arms in scattered light images are primarily detected around high luminosity stars with disks with wide gaps, which can be understood by the dependence of the spiral arm pitch angle on disk temperature and companion mass.

description: The present assignment examines the protection of the consumers from unfair commercial practices after the incorporation of the 2005/29/EC Directive in the Greek Law. After a short mention in the need of the consumers protection from the above practices and the various laws which have been from time to time published, we present the process of the publication of the above mentioned Directive, which concerns the unfair commercial practices, the field of the Directive's application, the Directive's structure, as well as the changes it has introduced to the Greek Law. Then , we examine the Directive's relationship with the Law 146/1914 and we analyze its main points. Next, the categorization of the unfair commercial practices follows. Τhere, apart from the general clause that concerns the unfair commercial practices, the misleading and the aggressive practices, as special categories are also included, as well as a catalog of per se forbidden practices. Furthermore, we analyze the court protection, which the Greek law offers regarding this subject. This court protection is divided into, civil, administrative and penal. Conclusively, we present a general review of the Directive and a number of conclusions.
A modelling study of the 1976 climate regime shift in the North Pacific Ocean
Creators: name: Wu, Qiuying
Publisher: name: University of British Columbia
Year: 2009

description: During the 1976 climate regime shift, the Aleutian low deepened. Many studies have shown that the oceanic shift was mainly driven by the atmospheric dynamics. In this thesis numerical studies to investigate the oceanic interdecadal variation as the result of the 1976 climate shift have been carried out with the GFDL OGCM. Two interdecadal experiments are performed. One is forced by monthly wind stress climatology for 1976- 1988 and relaxed to monthly SST climatology from the same time period. The other is forced by monthly wind stress climatology for 1952-1975 and monthly SST climatology from the same time period. The same sea surface salinity monthly climatology data is used throughout all the experiments. The simulated ocean circulations exhibit significant interdecadal variations. The gyre circulations are spun up both in the subarctic region and the subtropical region, except in the northern and eastern part of the Gulf of Alaska where the gyral circulation is weakened. The large scale surface cooling in the central North Pacific and the warming along the west coast of North America are simulated. The intensified surface Ekman drifts are very important in generating the thermal variation near the surface, especially in mid and high latitudes. The deepening of the Aleutian Low generates stronger surface divergence in the subarctic area and stronger convergence in the subtropic. Consequently the upwelhng in the subarctic region is increased, with a maximum increase of 108% at a depth of 60 m. The downwelling in the subtropical area is enhanced as well. Along the coast of North America above 40°7Y, there is an increase in downwelling, which is consistent with the weakening of the Alaskan gyre. The significant variations in upwelling in the subarctic and downwelling in subtropical regions are confined approximately above a few hundred meters depth. By working with the large vertical temperature gradients, they produce large scale subsurface thermal variation, with the cooling in the subarctic and warming in the subtropic. The depth range of the subsurface thermal variation is limited to above 650 m depth. The meridional circulation and heat transport are changed consequently. In low latitudes the poleward heat transport is increased. In the mid latitudes the equatorward heat transport is increased and mainly contributed by the meridional component, though the gyre and diffusion components are not negligible. The heat transport in high latitudes, poleward and very small, is increased. The estimation of the salinity effect on the current studies shows that a change in surface salinity forcing fields by an amount of 0.0817ppt in subarctic area does not have significant impacts on the results of this study.

description: In this work we analyze the relation between the multiplicative decomposition $\mathbf F=\mathbf F^{e}\mathbf F^{p}$ of the deformation gradient as a product of the elastic and plastic factors and the theory of uniform materials. We prove that postulating such a decomposition is equivalent to having a uniform material model with two configurations - total $ϕ$ and the inelastic $ϕ_{1}$. We introduce strain tensors characterizing different types of evolutions of the material and discuss the form of the internal energy and that of the dissipative potential. The evolution equations are obtained for the configurations $(ϕ,ϕ_{1})$ and the material metric $\mathbf g$. Finally the dissipative inequality for the materials of this type is presented.It is shown that the conditions of positivity of the internal dissipation terms related to the processes of plastic and metric evolution provide the anisotropic yield criteria.

description: Magnetic switching of a single molecular magnet (SMM) due to spin-polarized current flowing between ferromagnetic metallic electrodes is investigated theoretically. Magnetic moments of the electrodes are assumed to be collinear and parallel to the magnetic easy axis of the molecule. Electrons tunneling through a barrier between magnetic leads are coupled to the SMM via exchange interaction. The current flowing through the system as well as the spin relaxation times of the SMM are calculated from the Fermi golden rule. It is shown that spin of the SMM can be reversed by applying a voltage between the two magnetic electrodes. Moreover, the switching is reflected in the corresponding current-voltage characteristics.

description: Experimental results for covalent glasses have highlighted the existence of a new self-organized phase due to the tendency of glass networks to minimize internal stress. Recently, we have shown that an equilibrated self-organized two-dimensional lattice-based model also possesses an intermediate phase in which a percolating rigid cluster exists with a probability between zero and one, depending on the average coordination of the network. In this paper, we study the properties of this intermediate phase in more detail. We find that microscopic perturbations, such as the addition or removal of a single bond, can affect the rigidity of macroscopic regions of the network, in particular, creating or destroying percolation. This, together with a power-law distribution of rigid cluster sizes, suggests that the system is maintained in a critical state on the rigid/floppy boundary throughout the intermediate phase, a behavior similar to self-organized criticality, but, remarkably, in a thermodynamically equilibrated state. The distinction between percolating and non-percolating networks appears physically meaningless, even though the percolating cluster, when it exists, takes up a finite fraction of the network. We point out both similarities and differences between the intermediate phase and the critical point of ordinary percolation models without self-organization. Our results are consistent with an interpretation of recent experiments on the pressure dependence of Raman frequencies in chalcogenide glasses in terms of network homogeneity.

description: Knot polynomials colored with symmetric representations of $SL_q(N)$ satisfy difference equations as functions of representation parameter, which look like quantization of classical ${\cal A}$-polynomials. However, they are quite difficult to derive and investigate. Much simpler should be the equations for coefficients of differential expansion nicknamed quantum ${\cal C}$-polynomials. It turns out that, for each knot, one can actually derive two difference equations of a finite order for these coefficients, those with shifts in spin $n$ of the representation and in $A=q^N$. Thus, the ${\cal C}$-polynomials are much richer and form an entire ring. We demonstrate this with the examples of various defect zero knots, mostly discussing the entire twist family.

Correlation of Rock Quality Designation and Rock Scour Around Bridge Piers and Abutments Founded on Rock

description: Local scour around the base of a bridge pier or abutment occurs as the result of flow acceleration around the obstruction, formation of a vertical pressure gradient along the upstream end, and generation of vortices at the base of the structure. The flow patterns around piers and abutments are complex in detail, and the complexity increases as a scour hole forms in the bed around the structures. The potential for local scour at a bridge pier or abutment needs to be estimated so that foundations can be designed to resist failure during large floods. While procedures have been suggested for estimating local scour depths at bridge piers and abutments located on, or in unconsolidated alluvial material, only interim FHWA guidelines (July 1991) in the form of a memorandum are available for evaluating the scour potential at footings placed on rock. The empirical guides relate quantifiable geotechnical indices to a qualitative measure of the ability of the foundation rock to resist erosi on. However, the procedure lacks documented proof or verification by means of either experiment or observation. To test the validity of some of the more significant FHWA guidelines for assessing the rock scour, on-site inspections of some 400 bridges with footings located on exposed rock were performed. A large number of bridge abutments and piers in Kentucky were found to have been placed on rock foundations that are visible during low flow. These inspections show that scour at bridge piers and abutments placed on rock does occur. As a means of evaluating rock scour at existing sites, a rock scour hazard rating system was proposed. Based on the inspections, rock scour is not a significant problem in Kentucky. Statistically, only about 0.5 percent of the observed bridges had significant vertical scour. Generally, when scour was observed the depth of vertical scour was less than about 10 inches. In the few cases observed, the scour holes could be easily repaired by filling with concrete. An approximate relationship between vertical rock scour depth next to the abutment, or pier, and Rock Quality Designation (RQD) was developed. Also, an approximate relationship between horizontal rock scour penetration beneath a pier, or abutment, footer and Rock Quality Designation (RQD) is presented. Generally, the geology at sites where scour was observed consisted of interbedded layers of limestone and shale layers, or very thin shale partings. Freezing and thawing apparently caused the blocks to breakup and flooding velocities of the streams tended to wash out the blocks around footers.

description: An experimental investigation of sub-wavelength imaging by a wire medium slab is performed. A complex-shaped near field source is used in order to test imaging performance of the device. It is demonstrated that the ultimate bandwidth of operation of the constructed imaging device is 4.5% that coincides with theoretical predictions [Phys. Rev. E 73, 056607 (2006)]. Within this band the wire medium slab is capable of transmitting images with λ/15 resolution irrespectively of the shape and complexity of the source. Actual bandwidth of operation for particular near-field sources can be larger than the ultimate value but it strongly depends on the configuration of the source.

description: The Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189) is being conducted by the Kentucky Transportation Center on behalf of the Kentucky Transportation Cabinet. There are two main objectives of the study: 1) evaluation of the access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for the Campbell-Hausfeld Company facility located in Grayson County in the Lincoln Trail Area Development District (ADD) and KYTC Highway District #4. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task is ongoing and documented elsewhere.  The sites to be evaluated in this study were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the NHS, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used.  The site was visited for video recording on January 15, 1998 and for data collection on October 26, 1998. The facility is located on Embry Road west of KY 920. Other facilities in the area not contacted are Leggett and Platt, Vermont American, and Inoac. The surrounding area is generally rural. A phone survey was conducted with the facility manager early in the study process. The survey found that approximately 60 trucks per day normally access the facility while HIS data indicated 570 trucks travel along KY 920 at the site. The trucks are generally semitrailers with a maximum length of 53 feet. The freight handled at this facility is primarily air compressors and accessories. The only problem mentioned in the survey was a tight turning radius at the intersection of Embry Drive and KY 920. The phone survey information can be found in Appendix A.

description: We study the rheology of monodisperse and bidisperse emulsions with various droplet sizes (1 $μ$m -- 2 $μ$m diameter). Above a critical volume fraction $ϕ_c$, these systems exhibit solid-like behavior and a yield stress can be detected. Previous experiments suggest that for small thermal particles, rheology will see a glass transition at $ϕ_c = ϕ_g =0.58$; for large athermal systems, rheology will see a jamming transition at $ϕ_c = ϕ_J =0.64$. However, simulations point out that at the crossover of thermal and athermal regimes, the glass and jamming transitions may both be observed in the same sample. Here we conduct an experiment by shearing four oil-in-water emulsions with a rheometer. We observe both a glass and a jamming transition for our smaller diameter droplets, and only a jamming transition for our larger diameter droplets. The bidisperse sample behaves similarly to the small droplet sample, with two transitions observed. Our rheology data are well-fit by both the Herschel-Bulkley model and the Three Component model. Based on the fitting parameters, our raw rheological data would not collapse onto a master curve. Our results suggest that liquid-solid transitions in dispersions may not be universal, but depend on particle type.

description: We present detailed radiative transfer spectral synthesis models for the Iron Low Ionization Broad Absorption Line (FeLoBAL) active galactic nuclei (AGN) FIRST J121442.3+280329 and ISO J005645.1-273816. Detailed NLTE spectral synthesis with a spherically symmetric outflow reproduces the observed spectra very well across a large wavelength range. While exact spherical symmetry is probably not required, our model fits are of high quality and thus very large covering fractions are strongly implied by our results. We constrain the kinetic energy and mass in the ejecta and discuss their implications on the accretion rate. Our results support the idea that FeLoBALs may be an evolutionary stage in the development of more ``ordinary'' QSOs.

description: Clusters form the basis of a number of research study designs including survey and experimental studies. Cluster-based designs can be less costly but also less efficient than individual-based designs due to correlation between individuals within the same cluster. Their design typically relies on \textit{ad hoc} choices of correlation parameters, and is insensitive to variations in cluster design. This article examines how to efficiently design clusters where they are geographically defined by demarcating areas incorporating individuals and households or other units. Using geostatistical models for spatial autocorrelation we generate approximations to within cluster average covariance in order to estimate the effective sample size given particular cluster design parameters. We show how the number of enumerated locations, cluster area, proportion sampled, and sampling method affect the efficiency of the design and consider the optimization problem of choosing the most efficient design subject to budgetary constraints. We also consider how the parameters from these approximations can be interpreted simply in terms of `real-world' quantities and used in design analysis.

description: Το LPME είναι μια οπτική τεχνική που επιστρατεύεται για τον προσδιορισμό χαρακτηριστικών ενός αερολύματος. Συγκεκριμένα της μέσης διαμέτρου των σωματιδίων που απαρτίζουν το αερόλυμα και του κλάσματος όγκου. Η αρχή στην οποία βασίζεται για την εξαγωγή πληροφορίας είναι η εξάλειψη που υφίσταται ακτινοβολία πολλαπλού μήκους κύματος καθώς διέρχεται μέσω του αερολύματος. Η απώλεια έντασης περιγράφεται από τον νόμο Beer-Lambert.Το γενικό σχέδιο της παρούσας εργασίας ορίστηκε με τον καθορισμό τεσσάρων βασικών στόχων οι οποίοι αποτέλεσαν και τα σημεία στα οποία στηρίχθηκε η συγγραφή της εργασίας.Πρώτον η ανάπτυξη ενός νέου συστήματος DAQ που να εξυπηρετεί το LPME. Δεύτερον η κατασκευή ενός νέου συνόλου εφαρμογών λογισμικού για την αποθήκευση και διαχείριση των δεδομένων του LPME. Τρίτον η εξέταση του θεωρητικού πλαισίου στο οποίο στηρίζεται το LPME για την εξαγωγή αποτελεσμάτων. Τέταρτον η χρήση του LPME για την αποτίμηση των παραμέτρων αερολύματος αιθάλης που παράγει το CASt2 και η σύγκριση με δεδομένα από SMPS.Τα αποτελέσματα έδειξαν ότι το LPME αποτελεί ένα αξιόπιστο εργαλείο για τον προσδιορισμό του κλάσματος όγκου αιθάλης.Προς υποστήριξη αυτού έρχεται και το γεγονός της σχετικά καλής συμφωνίας με τα δεδομένα του SMPS. Όσο για την διάμετρο που προδιορίζει το LPME, φαίνεται ότι αυτή ταυτίζεται με την διάμετρο του πρωτογενούς σωματιδίου του συσσωματώματος αιθάλης και όχι με την διάμετρο του συσσωματώματος.
description: LPME (Long Path Multiwave Extinction analyzer) is an optical method that is used for the determination of aerosol characteristics, especially soot. In particular the mean diameter of the particles that consist the aerosol and the volume fraction. This method is based on the measurement of the extinction that undergoes a multiwavelenght laser beam as it travels through an aerosol. The extinction is described by the Beer-Lambert law. The present work is developed around four main tasks that were set and accomplished. The first was the development of a new DAQ system to support the LPME. The second was the development of the data treatment and analysis software. The third was the examination of some theoretical aspects concerning LPME. The last was the usage of the LPME, along with the newly developed software, for the determination of the characteristics of soot generated by CASt2 and the comparison with SMPS data.The results showed that the LPME is a reliable tool for the determination of soot volume fraction. In support of that comes also the relatively good correlation with SMPS data. As for the diameter determined by LPME, it seems that it is identified with the diameter of the primary particle of the soot aggregate than that of the aggregate itself.

description: Cough audio signal classification has been successfully used to diagnose a variety of respiratory conditions, and there has been significant interest in leveraging Machine Learning (ML) to provide widespread COVID-19 screening. However, there is currently no validated database of cough sounds with which to train such ML models. The COUGHVID dataset provides over 20,000 crowdsourced cough recordings representing a wide range of subject ages, genders, geographic locations, and COVID-19 statuses. First, we filtered the dataset using our open-sourced cough detection algorithm. Second, experienced pulmonologists labeled more than 2,000 recordings to diagnose medical abnormalities present in the coughs, thereby contributing one of the largest expert-labeled cough datasets in existence that can be used for a plethora of cough audio classification tasks. Finally, we ensured that coughs labeled as symptomatic and COVID-19 originate from countries with high infection rates, and that their expert labels are consistent. As a result, the COUGHVID dataset contributes a wealth of cough recordings for training ML models to address the world's most urgent health crises.

Electromagnetic coupling between the fluid core and its solid neighbours
Creators: name: Dumberry, Mathieu
Publisher: name: University of British Columbia
Year: 2009

description: At low-frequency, the nearly geostrophic force balance in the fluid core constrains axisymmetric fluid motions to be purely azimuthal and independent of position along the rotation axis. Fluid motions can thus be described by a set of concentric rigid cylinders, which are free to rotate about their common axis. When these cylinders are coupled by a magnetic field, the associated restoring forces give rise to torsional oscillations. These waves are thought to cause the observed fluctuations in the length of day by transferring angular momentum to the mantle and the inner core. The theory of torsional oscillations assumes that the stresses at the fluid-solid boundaries, which transfer angular momentum, do not alter the rigid nature of the fluid cylinders. This assumption is probably valid at the base of the mantle where the magnetic field is not large enough to alter the geostrophic balance in the fluid near the boundary. However, it is not valid at the inner core boundary (ICB) where higher field strengths are likely to perturb the geostrophic balance. In this case, the Lorentz force has to be retained in the momentum balance. A complete analytical solution is given for the influence of Lorentz forces in the core. The model problem involves a conducting and rotating fluid between two plane conducting boundaries in the presence of a background magnetic field. The solution gives us a clear view of how boundary layers form near the solid and how the coupling to the mantle and the inner core occurs.' More importantly, we can directly see how the inclusion of Lorentz forces alters the velocity from rigid rotation and how this velocity differs from that obtained with the torsional oscillation theory. For cylinders that terminate on the inner core, it is found that the rigid rotations are perturbed for a range of background magnetic field strength and frequencies. At decade periods, there is insufficient inertia to disrupt rigid rotations. However, for annual fluctuations, departures in the fluid velocity from rigid rotations are significant, which implies that the Lorentz force can not be neglected in the dynamics of the fluid core when calculating the electromagnetic coupling at the ICB.

description: Additional file 1: Figure S1. LUPSENIC study scheme. A loading dose of ATO was administered intravenously each of the first 4 days (as in-patients), then twice a week (as outpatients) during weeks 2 to 4. Figure S2. Dose escalation scheme (Continual Reassessment Method): The ATO doses were studied sequentially; patients were planned to receive 0.1 mg/kg, 0.15 mg/kg or 0.20 mg/kg. If a patient experienced possible dose limiting toxicity (DLT), defined as grade 3 non reversible AE and/or grade 4 toxicity or death), a mathematical model was used to estimate the observed toxicity probability and determine the ATO dose for the next included patient. The maximum tolerated Dose (MTD) had been defined as the dose at which a DLT occurred in 10% of patients.

description: We study the behaviour and properties of the solar wind using a 2.5D Alfvén wave driven wind model. We first systematically compare the results of an Alfvén wave (AW) driven wind model with a polytropic approach. Polytropic magnetohydrodynamic wind models are thermally driven, while Alfvén waves act as additional acceleration and heating mechanisms in the Alfvén wave driven model. We confirm that an AW-driven model is required to reproduce the observed bimodality of slow and fast solar winds. We are also able to reproduce the observed anti-correlation between the terminal wind velocity and the coronal source temperature with the AW-driven wind model. We also show that the wind properties along an eleven-year cycle differ significantly from one model to the other. The AW-driven model again shows the best agreement with observational data. Indeed, solar surface magnetic field topology plays an important role in the Alfvén wave driven wind model, as it enters directly into the input energy sources via the Poynting flux. On the other hand, the polytropic wind model is driven by an assumed pressure gradient; thus it is relatively less sensitive to the surface magnetic field topology. Finally, we note that the net torque spinning down the Sun exhibits the same trends in the two models, showing that the polytropic approach still captures correctly the essence of stellar winds.
