description: In recent years, the American Association of State Highway Transportation Officials (AASHTO) has recommended the use of resilient modulus for characterizing highway materials for pavement design. This recommendation evolved as result of a trend in pavement design of using mechanistic models. Although much progress has been made in recent years in developing mathematical, mechanistic pavement design models, results obtained from those models are only as good as the material parameters used in the models. Resilient modulus of aggregate bases is an important parameter in the mechanistic models. The main goal of this study was to establish a simple and efficient means of predicting the resilient modulus of different types of Kentucky crushed stone aggregate bases. To accomplish this purpose, resilient modulus tests were performed on several different types of aggregate bases commonly used in pavements in Kentucky. Specimens were remolded to simulate compaction conditions typically encountered in the field. Tests were performed on wet and dry specimens. The compacted specimens were 6 inches in diameter and 12 inches in height Crushed limestone base materials included Dense Graded Aggregate (DGA), and Crushed Stone Base (CSB). Number 57s, crushed river gravel, recycled concrete, and asphalt drainage blanket samples were submitted for testing by engineers of the Kentucky Transportation Cabinet.  A new mathematical resilient modulus model, developed in a previous study by researchers of the University of Kentucky Transportation Center (UKTC), was used to relate resilient modulus to any selected, or calculated, principal stresses in the aggregate base. This model improves the means of obtaining best data “fits” between resilient modulus and stresses. Furthermore, the resilient modulus can be predicted, using the UKTC resilient modulus model, when the stress condition and type of Kentucky base aggregate are known. Multiple regression analysis is used to obtain model coefficients, k1, k2, and k3, of the relationships between resilient modulus and confining and deviator stresses used in the testing procedure. Also, multiple regression analysis was performed using other models developed by the National Cooperative Highway Research Program (NCHRP Project 1-37A, 2001) and Uzan (1985) to obtain the model coefficient, k1, k2, and k3.  The resilient modulus data and the UKTC model, as well as models developed by NCHRP and Uzan, are readily available to design personnel of the Kentucky Transportation Cabinet. Computer software was developed in a client/server and Windows environment. This program is embedded in the Kentucky Geotechnical Database, which resides on a Cabinet server in Frankfort, Kentucky.

description: Automated three-dimensional (3D) object reconstruction is the task of building a geometric representation of a physical object by means of sensing its surface. Even though new single view reconstruction techniques can predict the surface, they lead to incomplete models, specially, for non commons objects such as antique objects or art sculptures. Therefore, to achieve the task's goals, it is essential to automatically determine the locations where the sensor will be placed so that the surface will be completely observed. This problem is known as the next-best-view problem. In this paper, we propose a data-driven approach to address the problem. The proposed approach trains a 3D convolutional neural network (3D CNN) with previous reconstructions in order to regress the \btxt{position of the} next-best-view. To the best of our knowledge, this is one of the first works that directly infers the next-best-view in a continuous space using a data-driven approach for the 3D object reconstruction task. We have validated the proposed approach making use of two groups of experiments. In the first group, several variants of the proposed architecture are analyzed. Predicted next-best-views were observed to be closely positioned to the ground truth. In the second group of experiments, the proposed approach is requested to reconstruct several unseen objects, namely, objects not considered by the 3D CNN during training nor validation. Coverage percentages of up to 90 \% were observed. With respect to current state-of-the-art methods, the proposed approach improves the performance of previous next-best-view classification approaches and it is quite fast in running time (3 frames per second), given that it does not compute the expensive ray tracing required by previous information metrics.

Subjects: subject: Transportation Engineering

description: The concept and feasibility of stockpiling and reusing hydrated lime-soil mixtures to stabilize particular areas on stabilization projects after the mixing contractor has departed were examined. In chemical stabilization of subgrades, situations often arise where additional areas need to be stabilized after the specialty contractor and mixing equipment have left the project. Field and laboratory investigations were performed to determine if a soil mixed with hydrated lime during routine lime subgrade stabilization could be mixed, stockpiled, and used later. In laboratory studies, hydrated lime-soil mixtures were stockpiled loosely in the laboratory. CBR specimens of the stockpile material were remolded and soaked at selected times. Values of CBR increased with increasing times. Those studies strongly indicated that hydrated soil-mixtures could be stockpile and reused.

description: Spin precession in Rubidium atoms is investigated through a pump-probe technique. The excited wave packet corresponds to a precession of spin and orbital angular momentum around the total angular momentum. We show that using shaped laser pulses allows us to control this dynamics. With a Fourier transform limited pulse, the wave packet is initially prepared in the bright state (coupled to the initial state) whereas a pulse presenting a $π$ step in the spectral phase prepares the wave packet in the dark state (uncoupled to the initial state).

description: The SPIRAL1 charge breeder is now under operation. Radioactive beam has already been delivered [1] to Physicist for performing experiment. Although charge breeding efficiencies demonstrated high performances for stable ion beams, those efficiencies regarding radioactive ion beams were found, in the first experiments, lower than expected. The beam optics, prior to the injection of the 1+ ions into the SPIRAL1 charge breeder, is of prime importance [2] for getting such high efficiencies. Moreover, the intensities of the radioactive ion beams are so low, that it is really difficult to tune the charge breeder. The tuning of the charge breeder for radioactive ion beams requires a particular procedure often referred as blind tuning. A stable beam hav-ing a close Brho (few percent) is required to find out the set of optic parameters preceding the tuning of the radioactive beam. Hence, it has been decided to focus our effort on that procedure as to get control of the 1+ beam optics leading to high charge breeding efficiencies whatever the 1+ mass, energy and Target Ion Source System (TISS) used. Being aware that each TISS provide ion beams with a specific energy spread DeltaE, and given that the acceptance energy win-dow of the charge breeder is rather narrow; that parameter must play also an important role in the whole charge breed-ing efficiency.

description: Metastable states in Ising spin-glass models are studied by finding iterative solutions of mean-field equations for the local magnetizations. Two different equations are studied: the TAP equations which are exact for the SK model, and the simpler `naive-mean-field' (NMF) equations. The free-energy landscapes that emerge are very different. For the TAP equations, the numerical studies confirm the analytical results of Aspelmeier et al., which predict that TAP states consist of close pairs of minima and index-one (one unstable direction) saddle points, while for the NMF equations saddle points with large indices are found. For TAP the barrier height between a minimum and its nearby saddle point scales as (f-f_0)^{-1/3} where f is the free energy per spin of the solution and f_0 is the equilibrium free energy per spin. This means that for `pure states', for which f-f_0 is of order 1/N, the barriers scale as N^{1/3}, but between states for which f-f_0 is of order one the barriers are finite and also small so such metastable states will be of limited physical significance. For the NMF equations there are saddles of index K and we can demonstrate that their complexity Sigma_K scales as a function of K/N. We have also employed an iterative scheme with a free parameter that can be adjusted to bring the system of equations close to the `edge of chaos'. Both for the TAP and NME equations it is possible with this approach to find metastable states whose free energy per spin is close to f_0. As N increases, it becomes harder and harder to find solutions near the edge of chaos, but nevertheless the results which can be obtained are competitive with those achieved by more time-consuming computing methods and suggest that this method may be of general utility.

description: A key component of the baryon cycle in galaxies is the depletion of metals from the gas to the dust phase in the neutral ISM. The METAL (Metal Evolution, Transport and Abundance in the Large Magellanic Cloud) program on the Hubble Space Telescope acquired UV spectra toward 32 sightlines in the half-solar metallicity LMC, from which we derive interstellar depletions (gas-phase fractions) of Mg, Si, Fe, Ni, S, Zn, Cr, and Cu. The depletions of different elements are tightly correlated, indicating a common origin. Hydrogen column density is the main driver for depletion variations. Correlations are weaker with volume density, probed by CI fine structure lines, and distance to the LMC center. The latter correlation results from an East-West variation of the gas-phase metallicity. Gas in the East, compressed side of the LMC encompassing 30 Doradus and the Southeast HI over-density is enriched by up to +0.3dex, while gas in the West side is metal-deficient by up to -0.5dex. Within the parameter space probed by METAL, no correlation with molecular fraction or radiation field intensity are found. We confirm the factor 3-4 increase in dust-to-metal and dust-to-gas ratios between the diffuse (logN(H)~20 cm-2) and molecular (logN(H)~22 cm-2) ISM observed from far-infrared, 21 cm, and CO observations. The variations of dust-to-metal and dust-to-gas ratios with column density have important implications for the sub-grid physics of chemical evolution, gas and dust mass estimates throughout cosmic times, and for the chemical enrichment of the Universe measured via spectroscopy of damped Lyman-alpha systems.

description: Objective: Neonatal outcomes in women with and without medically managed gestational diabetes mellitus (GDM) were compared after accounting for differences in maternal baseline characteristics using a propensity score (PS) analysis. Methods: Women without preexisting diabetes, delivering singletons during 2010-2017 in a large hospital, were eligible for inclusion. Using nearest-neighbour PS matching, women with non-pharmacological managed GDM were matched with women whose GDM was medically managed. A conditional logistic regression consequently compared the neonatal adverse outcomes between the groups after adjusting for gestational age, induction of labor, birth type, and number of ultrasounds conducted during the pregnancy. Results: Of the overall 10028 births, GDM was diagnosed in 930 (9.3%), of whom 710 (76.3%) were successfully matched. The conditional regressions found higher risk of neonatal adverse outcomes in neonates of women with non-pharmacological managed GDM compared to neonates of women with medically managed GDM. These included a higher risk of hypoglycemia (odds ratio (OR) 1.56, 95% confidence interval (CI) 1.03–2.38, p = 0.037), hypothermia (OR 2.29, 95%CI 1.05-5.00, p = 0.037), and birth injuries (OR 3.50, 95%CI 1.62–7.58, p = 0.001), and a higher risk of being small for gestational age (OR 2.06, 95%CI 1.01-4.18, p = 0.046) and being admitted to a special care unit (OR 2.04, 95%CI 1.29-3.21, p = 0.002). Conclusions: The increased neonatal morbidity associated with non-medicated GDM identified in our study may indicate that diet and lifestyle changes alone are not sufficient to achieve glycaemic control in some women with GDM. Our findings indicate that gestational diabetes management approach is independently associated with neonatal outcomes.

description: \emph{Ab initio} calculations of the structure and electronic density of states (DOS) of the perfect core-shell $Ag_{27}Cu_{7}$ nanoalloy attest to its $D_{5h}$ symmetry and confirm that it has only 6 non-equivalent (2 $Cu$ and 4 $Ag$) atoms. Analysis of bond-length, average formation energy, heat of formation of $Ag_{27}Cu_{7}$ and $L1_2$ $Ag-Cu$ alloys provide an explanation for the relative stability of the former with respect to the other nanoalloys in the same family. The HOMO-LUMO gap is found to be 0.77 eV, in agreement with previous results. Analysis of the DOS of $Ag_{27}Cu_{7}$, $L1_2$ $Ag-Cu$ alloys and related systems provides insight into the effects of low coordination, contraction/expansion and the presence of foreign atoms on the DOS of $Cu$ and $Ag$. While some characteristics of the DOS are reminiscent of those of the phonon-stable $L1_2$ $Ag-Cu$ alloys, the $Cu$ and $Ag$ states hybridize significantly in $Ag_{27}Cu_{7}$, compensating the $d$-band narrowing that each atom undergoes and hindering the dip in the DOS found in the bulk alloys. Charge density plots of $Ag_{27}Cu_{7}$ provide further insights into the relative strengths of the various interatomic bonds. Our results for the electronic and geometric structure of this nanoalloy can be explained in terms of length and strength hierarchies of the bonds, which may have implications also for the stability of alloy in any phase or size.

description: Van der Waals heterostructures consisting of Bernal bilayer graphene (BLG) and hexagonal boron nitride (hBN) are investigated. By performing first-principles calculations, we capture the essential BLG band structure features for several stacking and encapsulation scenarios. A low-energy model Hamiltonian, comprising orbital and spin-orbit coupling (SOC) terms, is employed to reproduce the hBN-modified BLG dispersion, spin splittings, and spin expectation values. Most important, the hBN layers open an orbital gap in the BLG spectrum, which can range from zero to tens of meV, depending on the precise stacking arrangement of the individual atoms. Therefore, large local band gap variations may arise in experimentally relevant moiré structures. Moreover, the SOC parameters are small (few to tens of µeV), just as in bare BLG, but are markedly proximity modified by the hBN layers. Especially when BLG is encapsulated by monolayers of hBN, such that inversion symmetry is restored, the orbital gap and spin splittings of the bands vanish. In addition, we show that a transverse electric field mainly modifies the potential difference between the graphene layers, which perfectly correlates with the orbital gap for fields up to about 1 V/nm. Moreover, the layer-resolved Rashba couplings are tunable by ∼5µeVperV/nm. Finally, by investigating twisted BLG/hBN structures, with twist angles between 6∘–20∘, we find that the global band gap increases linearly with the twist angle. The extrapolated 0∘ band gap is about 23 meV and results roughly from the average of the stacking-dependent local band gaps. Our investigations give insights into proximity spin physics of hBN/BLG heterostructures, which should be useful for interpreting experiments on extended as well as confined (quantum dot) systems.

description: Trapped ion in the Lamb-Dicke regime with the Lamb-Dicke parameter $η\ll1$ can be cooled down to its motional ground state using sideband cooling. Standard sideband cooling works in the weak sideband coupling limit, where the sideband coupling strength is small compared to the natural linewidth $γ$ of the internal excited state, with a cooling rate much less than $γ$. Here we consider cooling schemes in the strong sideband coupling regime, where the sideband coupling strength is comparable or even greater than $γ$. We derive analytic expressions for the cooling rate and the average occupation of the motional steady state in this regime, based on which we show that one can reach a cooling rate which is proportional to $γ$, while at the same time the steady state occupation increases by a correction term proportional to $η^{2}$ compared to the weak sideband coupling limit. We demonstrate with numerical simulations that our analytic expressions faithfully recover the exact dynamics in the strong sideband coupling regime.

description: In the process of translation, ribosomes read the genetic code on an mRNA and assemble the corresponding polypeptide chain. The ribosomes perform discrete directed motion which is well modeled by a totally asymmetric simple exclusion process (TASEP) with open boundaries. Using Monte Carlo simulations and a simple mean-field theory, we discuss the effect of one or two ``bottlenecks'' (i.e., slow codons) on the production rate of the final protein. Confirming and extending previous work by Chou and Lakatos, we find that the location and spacing of the slow codons can affect the production rate quite dramatically. In particular, we observe a novel ``edge'' effect, i.e., an interaction of a single slow codon with the system boundary. We focus in detail on ribosome density profiles and provide a simple explanation for the length scale which controls the range of these interactions.

We report a new search for the existence of sub-MeV sterile neutrinos using the decay-momentum reconstruction technique in the decay of $^7$Be. The experiment measures the total energy of the $^7$Li daughter atom from the electron capture decay of $^7$Be implanted into sensitive superconducting tunnel junction (STJ) quantum sensors. This first experiment presents data from a single STJ operated at a low count rate for a net total of 28 days, and provides exclusion limits on sterile neutrinos in the mass range from 100 to 850 keV that improve upon previous work by up to an order of magnitude.

description: The study of earth pressure distribution on buried structures has a great practical importance in constructing highway embankments above pipes and culverts. Based on Spangler’s research, the supporting strength of a conduit depends primarily on three factors: 1. the inherent strength of the conduit; 2. the distribution of the vertical load and bottom reaction; and, 3. the magnitude and distribution of lateral earth pressures which act against the sides of the structure. Considering high fills above them and high earth pressures they may experience, rigid culverts are usually used underneath highway embankments. To reduce high vertical earth pressures acting on a buried structure, ultra-lightweight Geofoam will be placed above a culvert in the field, at Russell County, KY. Before construction began, numerical analysis using FLAC 4.00 (Fast Lagrangian Analysis of Continua) had been performed to predict stresses on the culvert. Results of the analysis show that Geofoam has a great effect in reducing vertical stresses above and below the culvert. There are areas of high stress concentrations at the top and bottom of the concrete culvert if no Geofoam was placed above the culvert. After placing Geofoam above the culvert, the concentrated stress at the top can be reduced to 28 percent of the stress without Geofoam. The high stress at the bottom of culvert can be reduced to 42 percent of the stress without Geofoam. Stresses on the two sidewalls of the culvert were observed to have no significant change in values with and without Geofoam.

description: This report summarizes the condition assessment of the pavement structure on I-65 between 97.5 to 102.5. Three types of equipment were used to evaluate the present condition of the pavement: falling weight deflectormeter, ground penetrating radar, and coring machine, Results indicated that durability of the existing concrete surface appears to be the most detrimental problem encountered in this survey. Load-transfer across transverse joint appear to be in acceptable ranges. Limited areas were identified to have less than four inches of D.G.A. beneath the concrete pavement. These areas have also been experiencing the most differential settlement. In addition several areas are experiencing water trapped beneath the concrete surface due to inadequate pavement drainage.

description: By passing legislation in 2006 to mandate primary enforcement of the Kentucky state law requiring safety belt use for motor vehicle occupants, the state could expect to realize an overall savings of at least $118 million in direct medical costs over the ten-year period from 2006 to 2015. Charges to Medicaid over that period would be about $34 million less than under the current secondary enforcement model. In addition, there would be at least $67 million saved in medical costs to commercial insurers, $2.3 million to Medicare, $3.3 million to Worker’s Compensation, and $11.2 million to other sources.  These savings would be a direct result of an increase in the number of Kentuckians who would wear a safety belt if a primary enforcement law were in place. States that have enacted primary enforcement legislation in the past have experienced increases in safety belt use of as much as 18 percentage points. The National Highway Traffic Safety Administration (NHTSA) has stated that the average increase is between 10 and 15 percentage points. The savings given above assume that Kentucky would experience an increase of 13 percentage point s, which would move the state’s usage rate from 67 percent to 80 percent, which was the national average in 2004.  NHTSA has published estimates of the effectiveness of safety belts in preventing fatal and nonfatal injuries. The estimated effectiveness varies depending on the type of vehicle in which the occupant is riding (passenger car versus light truck), the type of safety belt used (lap belt only versus lap and shoulder belt ), and the occupant’s position in the vehicle (front seat versus rear seat). Linked collis ion report and hospital discharge data from Kentucky’s Crash Outcome Evaluation System (CODES) were used to estimate Kentucky’s overall safety belt effectiveness for preventing moderate-to-critical injury at 55 percent. This number was then used to calculate medical costs savings for Kentucky’s Medicaid program and other payers that would result from enactment of a primary enforcement law. Particular attention was given to traumatic brain injuries (TBI) and spinal cord injuries (SCI) because they often result in medical costs for years after the original injury.

description: Culvert extension under highway embankment construction is a regular and important practice when roadway widening occurs. At some existing sites, concrete thickness and reinforcing steel of culvert tops and walls were stepped-down in sections of the culvert under the embankment slopes. The part of the culvert positioned under the embankment slopes was constructed weaker because the stresses under the portions of the slopes are much less than the stresses acting on the culvert section located under the main portion of the embankment. When additional fill is placed over the culvert due to roadway widening, much greater stresses are imposed on the weaker portions of the culvert. To accommodate the increased stresses on the weaker portions of the culvert, lightweight material will be placed above the weaker portions of the culvert in the fields. Before construction begins, numerical analysis using FLAC 4.0 (Fast Lagrangian Analysis of Continua) was performed to predict stresses on the culvert. Results of the analysis show that geofoam has a great effect in reducing vertical stresses above and below the culvert. There are areas of high stress concentrations at the top and bottom of the concrete culvert if no geofoam was placed above the culvert. Placing geofoam above the culvert reduces the concentrated stresses at the top and bottom significantly. The stress reduction is a function of the size of geofoam and the distance between top of culvert and geofoam. To obtain an optimal practical situation, a numerical model was created to thoroughly analyze these factors. By considering these factors, effectual curves are obtained from the numerical analysis. When geofoam is placed directly on top of the culvert, the results indicate that the concentrated stresses at the top and bottom will be minimized, but it will require excavating the fill and replacing it with geofoam. The optimal situation for each culvert should be analyzed case by case. On the other hand, foam concrete can reduce load on the culvert if it is placed correctly. Valuable results using geofoam and foam concrete to reduce loads on a culvert are discussed in this report.

description: We demonstrate the spatial confinement of electronic excitations in a solid state system, within novel artificial structures that can be designed having arbitrary dimensionality and shape. The excitations under study are exciton-polaritons in a planar semiconductor microcavity. They are confined within a micron-sized region through lateral trapping of their photon component. Striking signatures of confined states of lower and upper polaritons are found in angle-resolved light emission spectra, where a discrete energy spectrum and broad angular patterns are present. A theoretical model supports unambiguously our observations.

Generalized Smoluchowski equation with correlation between clusters

Publisher: name: arXiv
Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: In this paper we compute new reaction rates of the Smoluchowski equation which takes into account correlations. The new rate K = KMF + KC is the sum of two terms. The first term is the known Smoluchowski rate with the mean-field approximation. The second takes into account a correlation between clusters. For this purpose we introduce the average path of a cluster. We relate the length of this path to the reaction rate of the Smoluchowski equation. We solve the implicit dependence between the average path and the density of clusters. We show that this correlation length is the same for all clusters. Our result depends strongly on the spatial dimension d. The mean-field term KMFi,j = (Di + Dj)(rj + ri)d-2, which vanishes for d = 1 and is valid up to logarithmic correction for d = 2, is the usual rate found with the Smoluchowski model without correlation (where ri is the radius and Di is the diffusion constant of the cluster). We compute a new rate: the correlation rate K_{i,j}^{C} (D_i+D_j)(r_j+r_i)^{d-1}M{\big(\frac{d-1}{d_f}}\big) is valid for d \leq 1(where M(α) = \sum+\infty i=1i\alphaNi is the moment of the density of clusters and df is the fractal dimension of the cluster). The result is valid for a large class of diffusion processes and mass radius relations. This approach confirms some analytical solutions in d 1 found with other methods. We also show Monte Carlo simulations which illustrate some exact new solvable models.

description: Van der Waals (vdW) heterostructures provide a rich playground to engineer electronic, spin, and optical properties of individual two-dimensional materials. We investigate the twist-angle and gate dependence of the proximity-induced exchange coupling in the monolayer transition-metal dichalcogenides (TMDCs) MoSe2 and WSe2 due to the vdW coupling to the ferromagnetic semiconductor CrI3, from first-principles calculations. A model Hamiltonian, which captures the relevant band edges at the K/K′ valleys of the proximitized TMDCs, is employed to quantify the proximity-induced exchange. Upon twisting from 0∘ to 30∘, we find a transition of the TMDC valence band (VB) edge exchange splitting from about −2 to 2meV, while the conduction band (CB) edge exchange splitting remains nearly unchanged at around −3meV. For the VB of WSe2 (MoSe2) on CrI3, the exchange coupling changes sign at around 8∘ (16∘). We find that even at the angles with almost zero spin splittings of the VB, the real-space spin polarization profile of holes at the band edge is highly nonuniform, with alternating spin up-and spin-down orbitals. Furthermore, a giant tunability of the proximity-induced exchange coupling is provided by a transverse electric field of a few V/nm. Within our first-principles framework, we are limited to commensurate structures, and thus considered a maximum strain of 2.2% for the individual monolayers. By investigating different atomic stacking configurations of the strained supercells, we demonstrate that proximity exchange varies locally in space within experimentally realistic setups. We complement our ab initio results by calculating the excitonic valley splitting to provide experimentally verifiable optical signatures of the proximity exchange. Specifically, we predict that the valley splitting increases almost linearly as a function of the twist angle. Furthermore, the proximity exchange is highly tunable by gating, allowing to tailor the valley splitting in the range of 0 to 12 meV in WSe2/CrI3, which is equivalent to external magnetic fields of up to about 60 T. Our results highlight the important impact of the twist angle and gating when employing magnetic vdW heterostructures in experimental geometries.
