description: In order to extend commercial vehicle enforcement coverage to routes that are not monitored by fixed weigh stations, Kentucky has developed and implemented a Remote Monitoring System (RMS) and a Virtual Weigh Station (VWS). The RMS captures images of passing trucks (from the side) and transmits those images to a nearby weigh station. Station personnel can view the images, read the USDOT number, and check the number against Kentucky’s Clearinghouse of motor carrier data. When a problem is detected with the carrier’s registration, taxes, or safety record, an officer can be dispatched to intercept the truck, perform the necessary checks, and, if appropriate, take corrective action. The VWS provides the same functionality as the RMS, but adds a weigh-in-motion system, so that enforcement personnel can also screen trucks for apparent weight violations. Preliminary assessments of the performance of the RMS and VWS have been performed. This report describes the RMS and VWS concepts, discusses the results of the preliminary assessments, and presents recommendations for moving forward with additional deployments and testing.

description: Nitrogen vacancy (NV) centers in diamond have attracted considerable recent interest for use in quantum sensing, promising increased sensitivity for applications ranging from geophysics to biomedicine. Conventional sensing schemes involve monitoring the change in red fluorescence from the NV center under green laser and microwave illumination. Due to the strong fluorescence background from emission in the NV triplet state and low relative contrast of any change in output, sensitivity is severely restricted by a high optical shot noise level. Here, we propose a means to avoid this issue, by using the change in green pump absorption through the diamond as part of a semiconductor external cavity laser run close to lasing threshold. We show theoretical sensitivity to magnetic field on the pT/sqrt(Hz) level is possible using a diamond with an optimal density of NV centers. We discuss the physical requirements and limitations of the method, particularly the role of amplified spontaneous emission near threshold and explore realistic implementations using current technology.

description: We consider a new approach to describe a quantum optical Bose-system with internal Gell-Mann symmetry by the SU(3)-symmetry polarization map in Hilbert space. The operational measurement in density (or coherency) matrix elements for the three mode optical field is discussed for the first time. We have introduced a set of operators that describes the quantum measurement procedure and the behavior of fluctuations for the amplitude and phase characteristics of three level system. The original twelve-port interferometer for parallel measurements of the Gell-Mann parameters is proposed. The quantum properties of W-qutrit states under the measurement procedure are examined.

description: This report outlines a rating system and details an evaluation procedure for the seismic evaluation of highway bridges. These processes are later used to investigate the structural integrity of selected highway bridges on and over the parkways in Western Kentucky. A total of 349 bridges were rated with the bridge ranking system, and 17 were selected for detailed seismic evaluation.  The capacity/demand ratio method developed by the Federal Highway Administration is employed for the detailed evaluation of bridges. The evaluation involves creating three-dimensional finite element models for all 17 bridges. Dynamic analysis is performed for a projected 250-year event. Among the four components required for proper evaluation, only expansion joints and bearings, and columns and footings were investigated.  The evaluating results indicate that the rating system is an effective means in determining and prioritizing highway bridges for seismic evaluation and retrofit processes. The different forms of deficiencies of the bridges are presented herein.
Lyman Limit Systems in Cosmological Simulations

subject: FOS: Physical sciences

description: We used cosmological simulation with self-consistent radiative transfer to investigate the physical nature of Lyman Limit systems at z=4. In agreement with previous studies, we find that most of Lyman Limit systems are ionized by the cosmological background, while higher column density systems seem to be illuminated by the local sources of radiation. In addition, we find that most of Lyman limit systems in our simulations are located within the virial radii of galaxies with a wide range of masses, and are physically associated with them (``bits and pieces'' of galaxy formation). While the finite resolution of our simulations cannot exclude an existence of a second population of self-shielded, neutral gas clouds located in low mass dark matter halos (``minihalos''), our simulations are not consistent with ``minihalos'' dominating the total abundance of Lyman limit systems.

Modular Multilevel Converter
Control of MMC

description: This paper presents a new control strategy for Modular Multilevel Matrix converters where the output frequency is higher then the input frequency. In operating points when ω$_{out}$ $ \geq \ $ ω$_{in}$ the energy pulsation in the converter cells are dominated by the second harmonic of the input frequency. These energy pulsations can be identified and compensated by inducing additional currents. The results are verified by simulation for a laboratory scaled prototype of the Modular Multilevel Matrix Converter.
Detecting faint Debris Discs around M dwarfs
Creators: name: Luppe, Patricia
Publisher: name: Zenodo
Year: 2024

description: M dwarfs, as the most common stars in our galaxy, are commonly observed in exoplanetary surveys. A growing number of earth-like planets are detected around M dwarfs. Still, a mystery is why we do not find planetesimal belts around these stars. Planetesimal belts form after the protoplanetary disc disappears. The leftover planetesimals collide and create dusty discs, a.k.a. debris discs. Herschel showed that debris discs around M dwarfs are rare (5%) in contrast to Sun-like stars (20%) and A-type stars (30%).
We analyzed a Herschel survey that observed 94 M dwarfs to find debris discs, where two new discs were detected.
To test the reasons for this, we created a synthetic population of discs around these M stars based on different assumptions for their properties. We then tested if IRAM or ALMA would detect these discs around this M dwarf sample. Even though ALMA had better detection rates than IRAM, we showed that the possibility of finding new and fainter discs around low-mass stars is limited for these facilities. We have now tested our discs around the 94 M dwarfs for AtLAST. At the maximum detection rate (depending on the exact disc assumptions) for AtLAST, almost all our synthetic M dwarf debris discs were detected. The advantages of AtLAST are the high sensitivity, a lower resolution compared to ALMA, and no maximum recoverable scale (MRS) because it is a single-dish telescope.
Discs around M dwarfs have a faint flux, and if they are split into several beams, most become undetectable for ALMA. For AtLAST, only a small number of discs is marginally resolved. Therefore, we calculate a ~50% higher detection rate than for ALMA. If we observed the 94 M dwarfs of the former DEBRIS Herschel survey with AtLAST, we could detect an order of magnitude more M dwarf debris discs.
Isotropic and Anisotropic Lattice Spacing Corrections for I=2 pi-pi Scattering from Effective Field Theory

description: The calculation of the finite lattice spacing corrections for I=2 pi-pi scattering is carried out for isotropic and anisotropic Wilson lattice actions. Pion masses and decay constants are also determined in this context. These results correct the phase shift calculated from the lattice, which is connected to the scattering length and effective range in this low energy scattering process. When in terms of the lattice-physical parameters for either Wilson action, these lattice spacing effects first appear at the next-to-leading order counter-terms.

description: It has been recently claimed that primordial magnetic fields could relieve the cosmological Hubble tension. We consider the impact of such fields on the formation of the first cosmological objects, mini-halos forming stars, for present-day field strengths in the range of $2\times 10^{-12}$ - $2\times 10^{-10}$ G. These values correspond to initial ratios of Alvén velocity to the speed of sound of $v_a/c_s\approx 0.03 - 3$. We find that when $v_a/c_s\ll 1$, the effects are modest. However, when $v_a\sim c_s$, the starting time of the gravitational collapse is delayed and the duration extended as much as by $Δ$z = 2.5 in redshift. When $v_a > c_s$, the collapse is completely suppressed and the mini-halos continue to grow and are unlikely to collapse until reaching the atomic cooling limit. Employing current observational limits on primordial magnetic fields we conclude that inflationary produced primordial magnetic fields could have a significant impact on first star formation, whereas post-inflationary produced fields do not.

Simulation models : a useful tool in the evaluation of planted coastal Douglas-fir silvicultural management
Creators: name: Onate, Nilda Elvira
Publisher: name: University of British Columbia
Year: 2009

description: This study showed how selected growth and yield simulations models compare in predicting the results of a set of prescriptions for planted stands of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco). Estimates of growth rate, mean diameter, and yield were compared over a rotation for various sites. An economic analysis of the projected estimates was conducted with particular focus on a site index of 30 m. The selected models showed a wide variation predicting the effects of treatments (individually or in combination) and in predicting yields. This variation was attributed mostly to the databases used to develop the mathematical expressions which predict growth. The response to commercial thinning, in particular, was based on diverse assumptions among the models. The growth resulting from the simulated use of a fertilizer differed in assumptions regarding the duration of the effects of the fertilizer, the increase and the acceleration of the volume growth rate, and the amount of volume produced. Model predictions were mostly in agreement for the simulation of stands established at low initial densities (400-1100 sph). Model predictions of total standing volume were in agreement for almost all the prescriptions for site index 30 m. The economic evaluation determined the best combination of a sequence of scheduled activities. Precommercial thinning in combination with commercial thinning proved to be a financially attractive management alternative for initial planting densities of 2500 sph. A stand planted at 1100 sph and commercially thinned at ages 40, 50 and 60 showed the best return, although entry at age 60 produced the highest net benefits. Stands planted at 2500 and 1600 sph and precommercially thinned did not offset the costs incurred in the prescription. Stands widely planted (400-1100 sph) did not generate an acceptable return on the investment.

description: In this work we study weighted total least squares problems on infinite dimensional spaces. We show that in most cases this problem does not admit a solution (except in the trivial case) and then, we consider a regularization on the problem. We present necessary conditions for the regularized problem to have a solution. We also show that, by restricting the regularized minimization problem to special subsets, the existence of a solution may be assured.

The mass splitting in an 331-TC coupled Scenario
Creators: name: Doff, A.
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The root of most of the technicolor (TC) problems lies in the way the ordinary fermions acquire their masses, where an ordinary fermion (f) couples to a technifermion (F) mediated by an Extended Technicolor (ETC) boson leading to fermion masses that vary with the ETC mass scale ($M_E$) as $1/M_E^2$. Recently, we discussed a new approach consisting of models where TC and QCD are coupled through a larger theory, in this case the solutions of these equations are modified compared to those of the isolated equations, and TC and QCD self-energies are of the Irregular form, which allows us to build models where ETC boson masses can be pushed to very high energies. In this work we extend these results for 331-TC models, in particular considering a coupled system of Schwinger-Dyson equations, we show that all technifermions of the model exhibit the same asymptotic behavior for TC self-energies. As an application we discuss how the mass splitting of the order $O(100)GeV$ could be generated between the second and third generation of fermions.

Global well-posedness, scattering and blow-up for the energy-critical, focusing, non-linear Schrodinger equation in the radial case

description: We prove, for the energy critical, focusing NLS, that for data whose energy is smaller than that of the standing wave, and whose homogeneous Sobolev norm H^1 is smaller than that of the standing wave and which is radial, we have global well-posedness and scattering in dimensions 3, 4 and 5. This is sharp since if the data is in the inhomogeneous Sobolev space H^1, of energy smaller than the standing wave but of larger homogeneous H^1 norm, we have blow-up in finite time. The result follows from a general method that we introduce into this type of critical problem. By concentration-compactness we produce a critical element, which modulo the symmetries of the equation is compact, has minimal energy among those which fail to have the conclusion of our theorem. In addition, we show that the dilation parameter in the symmetry, for this solution, can be taken strictly positive.We then establish a rigidity theorem that shows that no such compact, modulo symmetries, object can exist. It is only at this step that we use the radial hypothesis.The same analysis, in a simplified form, applies also to the defocusing case, giving a new proof of results of Bourgain and Tao.

description: The Duplex alternative is one of three designs for a second tidal dock adjacent to the Deurganck dock. The Boomerang (NL Boemerang) and L-square (NL Winkelhaak) alternatives have previously been evaluated through real time simulations while the L-square dock was also part of a traffic real time simulation study with four Ultra Large Container Ships (ULCS) interacting in the same virtual environment. The Duplex alternative has been examined in 20 simulation runs executed during two days by four pilots of the Flemish and Dutch pilotage and assisted by a tug pilot of Boluda or Antwerp Towage. The accessibility of a 400 m and 430 m ULCS is guaranteed for wind forces restricted to a maximum of 6 Bft with maximum flood and ebb current. Head in mooring has mainly been considered but also some head out outbound manoeuvres have been realised. Tug configurations (with at least three 80 ton tugs for 6 Bft) are proposed to assist the ULCS in these manoeuvres. In future research the results of these individual manoeuvres will be used as a start for traffic simulations with four ULCS in one virtual environment interacting with each other.

description: Laser plasma acceleration at kilohertz repetition rate has recently been shown to work in two different regimes, with pulse lengths of either 30 fs or 3.5 fs. We now report on a systematic study in which a large range of pulse durations and plasma densities were investigated through continuous tuning of the laser spectral bandwidth. Indeed, two LPA processes can be distinguished, where beams of the highest quality, with 5.4 pC charge and a spectrum peaked at 2-2.5 MeV are obtained with short pulses propagating in moderate plasma densities. Through Particle-in-Cell simulations the two different acceleration processes are thoroughly explained. Finally, we proceed to show the results of a 5-hour continuous and stable run of our LPA accelerator accumulating more than $\mathrm{18\times10^6}$ consecutive shots, with 2.6 pC charge and peaked 2.5 MeV spectrum. A parametric study of the influence of the laser driver energy through PIC simulations underlines that this unprecedented stability was obtained thanks to micro-scale density gradient injection. Together, these results represent an important step towards stable laser-plasma accelerated electron beams at kilohertz repetition rate.

description: Multicore CPU architectures have been established as a structure for general-purpose systems for high-performance processing of applications. Recent multicore CPU has evolved as a system architecture based on non-uniform memory architecture. For the technique of using the kernel space that shifts the tasks to the ideal memory node, the characteristics of the applications of the user-space cannot be considered. Therefore, kernel level approaches cannot execute memory scheduling to recognize the importance of user applications. Moreover, users need to run applications after sufficiently understanding the multicore CPU based on non-uniform memory architecture to ensure the high performance of the user's applications. This paper presents a user-space memory scheduler that allocates the ideal memory node for tasks by monitoring the characteristics of non-uniform memory architecture. From our experiment, the proposed system improved the performance of the application by up to 25% compared to the existing system.
Nonextensive theory of dark matter and gas density profiles

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Pronounced core-halo patterns of dark matter and gas density profiles, observed in relaxed galaxies and clusters, were hitherto fitted by empirical power-laws. On the other hand, similar features are well known from astrophysical plasma environments, subject to long-range interactions, modeled in the context of nonextensive entropy generalization. We link nonextensive statistics to the problem of density distributions in large-scale structures and provide fundamentally derived density profiles, representing accurately the characteristics of both, dark matter and hot plasma distributions, as observed or generated in simulations. The bifurcation of the density distribution into a kinetic dark matter and thermodynamic gas branch turns out as natural consequence of the theory and is controlled by a single parameter kappa, measuring physically the degree of coupling within the system. Consequently, it is proposed to favor nonextensive distributions, derived from the fundamental physical context of entropy generalization and accounting for nonlocality and long-range interactions in gravitationally coupled systems, when modeling observed density profiles of astrophysical structures.

description: Using a new result for the first moment of the hadronic production cross section at order ${\cal O}(α_s^3)$, and new data on the $J/ψ$ and $ψ'$ resonances for the charm quark, we determine the \msb masses of the charm and bottom quarks to be $\bar{m}_c(\bar{m}_c) = 1.295 \pm 0.015$ GeV and $\bar{m}_b(\bar{m}_b) = 4.205 \pm 0.058$ GeV. We assume that the continuum contribution to the sum rules is adequately described by pQCD. While we observe a large reduction of the perturbative error, the shifts induced by the theoretical input are very small. The main change in the central value of $m_c$ is related to the experimental data. On the other hand, the value of $m_b$ is not changed by our calculation to the assumed precision.

Evaluation of oral rinse elastase in patients with periodontal diseases
Creators: name: Pauletto, Nathalie Christine
Publisher: name: University of British Columbia
Year: 2009

description: The present study is a follow-up to a previous study by Uitto et al. (1996) on salivary elastase activity in periodontal diseased patients. It was carried out in an attempt to understand why oral elastase activity is low in a small patient population with periodontitis while it is high in most patients. Oral rinse samples were collected at one or more occasions in patients with different levels of periodontal disease (n=43) and in healthy subjects (n=20). Subgroups of smokers (n=l 1) and patients with early onset forms of periodontal disease (EOP) (n=3) were also included in the study. Salivary elastase activity and PMN and epithelial cell counts were determined for each patient. Post operatory salivary samples for some of the patients (n=9) were also measured for elastase activity. The specificity of the salivary elastase test was 85%. Smokers and EOP patients affected the sensitivity of the salivary elastase test as a majority of these patients had low elastase activity in their samples. The study also found a correlation between the number of PMNs and elastase activity in patients with periodontitis compared with healthy subjects. These cells were twice as numerous in periodontitis patients compared to healthy subjects. Since a majority of periodontitis patients showed true positive results this test may have some value as a home diagnostic test prior to any dental appointment in subjects who are at risk for periodontal disease. Future studies are needed however to determine if this test should be limited to subjects in a certain age group category and/or in subjects who are otherwise in good general health and those who do not smoke.

description: We present analytic estimates of the fractional uncertainties on the mass, radius, surface gravity, and density of a transiting planet, using only empirical or semi-empirical measurements. We first express these parameters in terms of transit photometry and radial velocity (RV) observables, as well as the stellar radius $R_{\star}$, if required. In agreement with previous results, we find that, assuming a circular orbit, the surface gravity of the planet ($g_p$) depends only on empirical transit and RV parameters; namely, the planet period $P$, the transit depth $δ$, the RV semi-amplitude $K_{\star}$, the transit duration $T$, and the ingress/egress duration $τ$. However, the planet mass and density depend on all these quantities, plus $R_{\star}$. Thus, an inference about the planet mass, radius, and density must rely upon an external constraint such as the stellar radius. For bright stars, stellar radii can now be measured nearly empirically by using measurements of the stellar bolometric flux, the effective temperature, and the distance to the star via its parallax, with the extinction $A_V$ being the only free parameter. For any given system, there is a hierarchy of achievable precisions on the planetary parameters, such that the planetary surface gravity is more accurately measured than the density, which in turn is more accurately measured than the mass. We find that surface gravity provides a strong constraint on the core mass fraction of terrestrial planets. This is useful, given that the surface gravity may be one of the best measured properties of a terrestrial planet.

description: The recent discovery of methods to isolate graphene, a one-atom-thick layer of crystalline carbon, has raised the possibility of a new class of nano-electronics devices based on the extraordinary electrical transport and unusual physical properties of this material. However, the experimental realization of devices displaying these properties was, until now, hampered by the influence of the ambient environment, primarily the substrate. Here we report on the fabrication of Suspended Graphene devices and on studies of their electrical transport properties. In these devices, environmental disturbances were minimized allowing unprecedented access to the intrinsic properties of graphene close to the Dirac Point (DP) where the energy dispersion of the carriers and their density-of-states vanish linearly giving rise to a range of exotic physical properties. We show that charge inhomogeneity is reduced by almost one order of magnitude compared to that in Non-Suspended Graphene devices. Moreover, near the DP, the mobility exceeds 100,000 cm2/Vs, approaching theoretical predictions for evanescent transport in the ballistic model.

Response to Scheuer-Yariv: "A Classical Key-Distribution System based on Johnson (like) noise -How Secure?"

Publisher: name: arXiv
Year: 2006
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: We point out that the claims in the comment-paper of Scheuer and Yariv are either irrelevant or incorrect. The idealized Kirchoff-loop-Johnson-like-noise (KLJN) scheme is totally secure therefore it is more secure than idealized quantum communication schemes which can never be totally secure because of the inherent noise processes in those communication schemes and the statistical nature of eavesdropper detection based on error statistics. On the other hand, with sufficient resources, a practical/non-ideal realization of the KLJN cipher can arbitrarily approach the idealized limit and outperform even the idealized quantum communicator schemes because the non-ideality-effects are determined and controlled by the design. The cable resistance issue analyzed by Scheuer and Yariv is a good example for that because the eavesdropper has insufficient time window to build a sufficient statistics and the actual information leak can be designed. We show that Scheuer's and Yariv's numerical result of 1% voltage drop supports higher security than that of quantum communicators. Moreover, choosing thicker or shorter wires can arbitrarily reduce this voltage drop further; the same conclusion holds even according to the equations of Scheuer and Yariv.

Radiative Penrose process: Energy Gain by a Single Radiating Charged Particle in the Ergosphere of Rotating Black Hole

description: We demonstrate an extraordinary effect of energy gain by a single radiating charged particle inside the ergosphere of a Kerr black hole in presence of magnetic field. We solve numerically the covariant form of the Lorentz-Dirac equation reduced from the DeWitt-Brehme equation and analyze energy evolution of the radiating charged particle inside the ergosphere, where the energy of emitted radiation can be negative with respect to a distant observer in dependence on the relative orientation of the magnetic field, black hole spin and the direction of the charged particle motion. Consequently, the charged particle can leave the ergosphere with energy greater than initial in expense of black hole's rotational energy. In contrast to the original Penrose process and its various modification, the new process does not require the interactions (collisions or decay) with other particles and consequent restrictions on the relative velocities between fragments. We show that such a Radiative Penrose effect is potentially observable and discuss its possible relevance in formation of relativistic jets and in similar high-energy astrophysical settings.

Isolated, slowly evolving, and dynamical trapping horizons: geometry and mechanics from surface deformations

Publisher: name: arXiv
Year: 2006
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We study the geometry and dynamics of both isolated and dynamical trapping horizons by considering the allowed variations of their foliating two-surfaces. This provides a common framework that may be used to consider both their possible evolutions and their deformations as well as derive the well-known flux laws. Using this framework, we unify much of what is already known about these objects as well as derive some new results. In particular we characterize and study the "almost-isolated" trapping horizons known as slowly evolving horizons. It is for these horizons that a dynamical first law holds and this is analogous and closely related to the Hawking-Hartle formula for event horizons.

Eternal observers and bubble abundances in the landscape

description: We study a class of ``landscape'' models in which all vacua have positive energy density, so that inflation never ends and bubbles of different vacua are endlessly ``recycled''. In such models, each geodesic observer passes through an infinite sequence of bubbles, visiting all possible kinds of vacua. The bubble abundance $p_j$ can then be defined as the frequency at which bubbles of type $j$ are visited along the worldline of an observer. We compare this definition with the recently proposed general prescription for $p_j$ and show that they give identical results.
Computing obstructions for existence of connections on modules

description: We consider the notion of a connection on a module over a commutative ring, and recall the obstruction calculus for such connections. The obstruction calculus is defined using Hochschild cohomology. However, in order to compute with Grobner bases, we need the conversion to a description using free resolutions. We describe our implementation in Singular 3.0, available as the library conn.lib. Finally, we use the library to verify some known results and to obtain a new theorem for maximal Cohen-Macaulay (MCM) modules on isolated singularities. For a simple hypersurface singularity of dimension one or two, it is known that all MCM modules admit connections. We prove that for a simple threefold hypersurface singularity of type A_n, D_n or E_n, only the free MCM modules admit connections if n is at most 50.

description: This paper presents a new approach to estimating the relationship between consumption of specific foods and foodborne illness in the United States. We apply this approach to the case of foodborne sporadic campylobacteriosis illness. Most foodborne illness is sporadic and not part of a widespread outbreak. Foodborne Campylobacter infections are widely thought to be linked to chicken and are highly seasonal, primarily driven by temperature. We find that chicken purchased for consumption at home is not associated with sporadic Campylobacter infection in the United States, while ground beef and berries purchased for consumption at home are. The association between seasonality and the rate of Campylobacter infections is stronger than the association with temperature.
