description: We investigate dynamical coupling timescales of a neutron star's superfluid core, taking into account the interactions of quantized neutron vortices with quantized flux lines of the proton superconductor in addition to the previously considered scattering of the charged components against the spontaneous magnetization of the neutron vortex line. We compare the cases where vortex motion is constrained in different ways by the array of magnetic flux tubes associated with superconducting protons. This includes absolute pinning to and creep across a uniform array of flux lines. The effect of a toroidal arrangement of flux lines is also considered. The inclusion of a uniform array of flux tubes in the neutron star core significantly decreases the timescale of coupling between the neutron and proton fluid constituents in all cases. For the toroidal component, creep response similar to that of the inner crust superfluid is possible.

description: © 2017 American Physical Society. A measurement of electron antineutrino oscillation by the Daya Bay Reactor Neutrino Experiment is described in detail. Six 2.9-GWth nuclear power reactors of the Daya Bay and Ling Ao nuclear power facilities served as intense sources of νe's. Comparison of the νe rate and energy spectrum measured by antineutrino detectors far from the nuclear reactors (∼1500-1950 m) relative to detectors near the reactors (∼350-600 m) allowed a precise measurement of νe disappearance. More than 2.5 million νe inverse beta-decay interactions were observed, based on the combination of 217 days of operation of six antineutrino detectors (December, 2011-July, 2012) with a subsequent 1013 days using the complete configuration of eight detectors (October, 2012-July, 2015). The νe rate observed at the far detectors relative to the near detectors showed a significant deficit, R=0.949±0.002(stat)±0.002(syst). The energy dependence of νe disappearance showed the distinct variation predicted by neutrino oscillation. Analysis using an approximation for the three-flavor oscillation probability yielded the flavor-mixing angle sin22θ13=0.0841±0.0027(stat)±0.0019(syst) and the effective neutrino mass-squared difference of |Δmee2|=(2.50±0.06(stat)±0.06(syst))×10-3 eV2. Analysis using the exact three-flavor probability found Δm322=(2.45±0.06(stat)±0.06(syst))×10-3 eV2 assuming the normal neutrino mass hierarchy and Δm322=(-2.56±0.06(stat)±0.06(syst))×10-3 eV2 for the inverted hierarchy.

description: © 2016 Elsevier B.V. Quadrature compressive sampling (QuadCS) is a sub-Nyquist sampling scheme for acquiring in-phase and quadrature (I/Q) components in radar. In this scheme, the received intermediate frequency (IF) signals are expressed as a linear combination of time-delayed and scaled replicas of the transmitted waveforms. For sparse IF signals on discrete grids of time-delay space, the QuadCS can efficiently reconstruct the I/Q components from sub-Nyquist samples. In practice, the signals are characterized by a set of unknown time-delay parameters in a continuous space. Then conventional sparse signal reconstruction will deteriorate the QuadCS reconstruction performance. This paper focuses on the reconstruction of the I/Q components with continuous delay parameters. A parametric spectrum-matched dictionary is defined, which sparsely describes the IF signals in the frequency domain by delay parameters and gain coefficients, and the QuadCS system is reexamined under the new dictionary. With the inherent structure of the QuadCS system, it is found that the estimation of delay parameters can be decoupled from that of sparse gain coefficients, yielding a beamspace direction-of-arrival (DOA) estimation formulation with a time-varying beamforming matrix. Then an interpolated beamspace DOA method is developed to perform the DOA estimation. An optimal interpolated array is established and sufficient conditions to guarantee the successful estimation of the delay parameters are derived. With the estimated delays, the gain coefficients can be conveniently determined by solving a linear least-squares problem. Extensive simulation results evidently demonstrate the superiority of the proposed algorithms in achieving super-resolution time-delay estimation and high-accuracy sparse signal reconstruction.

description: The 2007 NRS included, for the first time, measures to estimate the use of other potentially impairing drugs by drivers. Prior roadside surveys had collected breath samples to determine blood alcohol concentration (BAC). Due to developments in analytic toxicology, NHTSA determined it would be feasible in the 2007 survey to collect oral fluid and/or blood samples to determine driver use of a wide variety of other potentially impairing drugs. A pilot test conducted in 2005 demonstrated the feasibility of conducting this more complex survey procedure and confirmed that motorists would voluntarily participate in the study (Lacey, et al, 2007). The 2007 NRS was designed to produce national estimates of alcohol and drug use by drivers. Thus, the use rates shown below are national prevalence rates calculated from the percentage of subjects using alcohol or drugs and adjusted with an appropriate weighting scheme.

description: The Bureau of Transportation Statistics in partnership with the U.S. Department of Transportation's Office of Intermodalism and the Federal Highway Administration sponsored the development of an Intermodal Bottleneck Evaluation Tool (IBET) to provide information and assist transportation planners and policymakers in identifying potential freight bottlenecks in the U.S. transportation system. IBET analyzes freight moved through three types of intermodal facilities: airports (truck-air transfers); seaports (truck-water, rail-water, inland water-deep sea transfers); and truck-rail interchange terminals. It calculates and measures the intensity of infrastructure use for each intermodal facility; estimates the relative significance of these facilities to national, regional, and international freight movement; and ranks facilities on the intensity of use.

description: Nowadays, wound healing delay due to diabetes is considered to be closely related to the accumulation of advanced glycation end products (AGEs). Although mesenchymal stem cells (MSCs) exhibit positive effects on diabetic wound healing, related mechanisms are still not fully elucidated. It has been reported that MSCs can improve the activity of autophagy in injured tissues, thereby playing an important role in wound healing. The autophagy induced by MSCs may be beneficial to diabetic wound healing via removing AGEs, which provide new ideas for clinical treatment of diabetic wounds with the potential of broad application prospects. In this study, the current research situation and application prospect of umbilical cord-derived MSCs on the clearance of AGEs in diabetic wound were reviewed.

description: Selection of the most suitable substrate for a Microstrip antenna is a matter of prime importance. This is because many limitations of the microstrip antenna such as high return loss, low gain and low efficiency can be overcome by selecting an appropriate substrate for fabrication of the antenna, without shifting the resonant frequency significantly. The substate properties such as its dielectric constant, loss tangent have a pronounced effect on the antenna characteristics. Some of the critical properties that are to be taken care of while selecting a dielectric are homogeneity, moisture absorption and adhesion of metal- foil cladding. In this paper a comprehensive study of the effect of variation of substrate material on the antenna properties has been presented.

description: We discuss self-consistently obtained ground-state electronic properties of monolayers of graphene and a number of 'beyond graphene' compounds, including films of transition-metal dichalcogenides (TMDs), using the recently proposed strongly constrained and appropriately normed (SCAN) meta-generalized gradient approximation (meta-GGA) to the density functional theory. The SCAN meta-GGA results are compared with those based on the local density approximation (LDA) as well as the generalized gradient approximation (GGA). As expected, the GGA yields expanded lattices and softened bonds in relation to the LDA, but the SCAN meta-GGA systematically improves the agreement with experiment. Our study suggests the efficacy of the SCAN functional for accurate modeling of electronic structures of layered materials in high-Throughput calculations more generally.

A coupled set of equations in terms of the velocity and a tensor variable to represent the deformation is introduced to show that there is a bifurcation from a straight motion to a circular motion of a single particle. Dynamics of assembly of the particles is studied numerically where there is a global interaction such that the particles tend to cause an orientational order.

description: © 2017, The Author(s). Understanding and reasoning about phenomena at scales outside human perception (for example, geologic time) is critical across science, technology, engineering, and mathematics. Thus, devising strong methods to support acquisition of reasoning at such scales is an important goal in science, technology, engineering, and mathematics education. In two experiments, we examine the use of analogical principles in learning about geologic time. Across both experiments we find that using a spatial analogy (for example, a time line) to make multiple alignments, and keeping all unrelated components of the analogy held constant (for example, keep the time line the same length), leads to better understanding of the magnitude of geologic time. Effective approaches also include hierarchically and progressively aligning scale information (Experiment 1) and active prediction in making alignments paired with immediate feedback (Experiments 1 and 2).
On the experimental investigation of vortex excited pressure fluctuations

Year: 2011

description: Construction and calibration of a piezoelectric transducer capable of measuring acoustic level pressure fluctuations occurring on the surface of a body due to shed vortices is described. The application of the transducer as a wake survey equipment is also explained. The fluctuating pressure and wake geometry study carried out using two dimensional models of several bluff and streamlined bodies indicate that (1) Fluctuating lift coefficient decreases with reduction in bluffness of the body. (2) For square and rectangular cylinders, as well as for the elliptic cylinder at large angles of attack, the amplitude of fluctuating pressure is minimum at the points where static pressure is maximum. (3) Fluctuating lift coefficient for the bodies with sharp leading edge (e.g. square and rectangular cylinders) is considerably larger than the corresponding static value, while for the circular cylinder, elliptic cylinder and the wing, the fluctuating coefficients were found to be smaller than their static counterpart. (4) The self excited motion of the body, particularly a bluff body, does not affect either the frequency of shedding vortices or the fluctuating pressure, for frequencies above vortex resonance.

Commuter rail passengers are able to connect to other transportation modes at 8121 of the 1,160 stations served by commuter trains that operate over the tracks of the national rail network.2 The percentage of commuter rail stations with intermodal connectivity exceeds that of the other modes (airline, intercity rail, and ferries) included thus far in the Bureau of Transportation Statistics' Intermodal Passenger Connectivity Database (IPCD). The commuter rail network covers 34 metropolitan areas across the country and provides regional rail service within a single or two adjacent metropolitan areas. Commuter trains, which may be either diesel or electrically powered, operate over tracks of the national rail system, frequently sharing the same right-of-way with freight trains or intercity passenger trains. They generally operate from outlying stations within a metropolitan area to the predominant city in that area.3 However, a few commuter rail systems operate between adjacent metropolitan areas.
Quantum Adiabatic Computation With a Constant Gap is Not Useful in One Dimension

Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We show that it is possible to use a classical computer to efficiently simulate the adiabatic evolution of a quantum system in one dimension with a constant spectral gap, starting the adiabatic evolution from a known initial product state. The proof relies on a recently proven area law for such systems, implying the existence of a good matrix product representation of the ground state, combined with an appropriate algorithm to update the matrix product state as the Hamiltonian is changed. This implies that adiabatic evolution with such Hamiltonians is not useful for universal quantum computation. Therefore, adiabatic algorithms which are useful for universal quantum computation either require a spectral gap tending to zero or need to be implemented in more than one dimension (we leave open the question of the computational power of adiabatic simulation with a constant gap in more than one dimension).

Effects of biaxial strain on the improper multiferroicity in h-LuFe O3 films studied using the restrained thermal expansion method
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2017
Subjects: cond-mat.mtrl-sci

description: © 2017 American Physical Society. Elastic strain is potentially an important approach in tuning the properties of the improperly multiferroic hexagonal ferrites, the details of which, however, have been elusive due to experimental difficulties. Employing the method of restrained thermal expansion, we have studied the effect of isothermal biaxial strain in the basal plane of h-LuFeO3 (001) films. The results indicate that a compressive biaxial strain significantly enhances the K3 structural distortion (the order parameter of the improper ferroelectricity), and the effect is larger at higher temperatures. The compressive biaxial strain and the enhanced K3 structural distortion together cause an increase in the electric polarization and a reduction in the canting of the weak ferromagnetic moments in h-LuFeO3, according to our first principles calculations. These findings are important for understanding the strain effect as well as the coupling between the lattice and the improper multiferroicity in h-LuFeO3. The experimental elucidation of the strain effect in h-LuFeO3 films also suggests that the restrained thermal expansion can be a viable method to unravel the strain effect in many other thin film materials.

An Investigation Of The Impact Of Broken Monofilaments On The Performance Of Titanium Matrix Composites
Creators: name: Fekadu Kebede, Thomas
Publisher: name: University of Surrey
Year: 2024

description: The adoption of continuously reinforced titanium matrix composites (TMCs) for lightweight components in aerospace applications is currently limited, in part, by a lack of understanding of manufacturing flaws observed in the literature. This study examines the role of groups of broken monofilaments that might be induced during the manufacture of TMCs due to its prevalence in other manufacturing processes.
description: To quantify the impact of broken monofilament on performance a method of introducing seeded defects was developed. Samples with broken monofilaments were uniaxially tensile tested with 2D digital image correlation (DIC) for strain mapping. The specimens with seeded defects were found to exhibit similar tensile behaviour to that of the non-defect control specimens. DIC indicated that damage occurred (i) near the seeded breaks, (ii) at the coupon edges, and (iii) apparently randomly within the sample. Metallography of tested samples confirmed the three locations of damage clusters corresponding to DIC measurements. Damage initiation at multiple sites indicates that the defect's impact on tensile performance is limited.
description: Tension-tension fatigue at σmax = 950 MPa, R=0.1, and a frequency of 3 Hz was conducted on specimens with seeded defects. The seeded defects were not the preferred sites for fatigue crack initiation, instead the coupon edges and surface pits acted as the preferred initiation sites.
description: Microstructural characterisation of Ti-3Al-2.5V was conducted using EBSD. Comparison between composite and monolithic samples showed broadly similar texture, grain size, and grain shape. A moderate transverse texture was observed in both the monolithic material and the composite matrix which could result in slight anisotropy.
description: FEA was conducted to provide an understanding of the stress redistribution due to the induced broken monofilament defects. The neighbouring intact monofilaments see an 11% increase in stress. This differs significantly from experimental findings, reported in the literature, for single-ply composites where the stress redistribution resulted in an increase of 40% on the nearest neighbour (Mcdonald et al. 2003).
description: In conclusion, the use of continuous reinforced TMCs are likely to be tolerant of broken monofilaments in multi-ply layup under both quasi-static and fatigue loading. Further research is required to further validate and extend these findings to other matrices and composite architectures.
The thermal wedge effect in hydrodynamic lubrication
Creators: name: Dvorak, Frank Arthur
Publisher: name: University of British Columbia
Year: 2011

description: The' 'thermal wedge' effect in hydrodynamic lubrication has been studied both theoretically - and experimentally. The friction theory has been refined to take into consideration the effect on friction of a variation of temperature across the film from the bearing to the disk surface. The theoretical pressure and temperature equations formulated by Currie were used in conjunction with the friction equation to obtain theoretical performance curves. Tests were carried out on a set of bearings having three, four and five pad configurations. Two different bearing materials were used, namely, babbitt, and Delrin A.F. fiber/resin. Circumferential oil rings were fitted into the assembly to restrict the radial flow of oil, thereby ensuring full lubrication of the bearings. Experimental observations proved that a thermal gradient across the film did exist, thus justifying the basic assumption in the variable viscosity analysis. Experimental coefficients of friction compared favourably with predicted values. The agreement was better than by-earlier theories. The results indicate that bearing performance is improved by the use of oil restrictor rings (actual load carrying capacities were more than doubled). The optimum bearing .configuration was that of a four-pad babbitt bearing. Although the Delrin A F bearing performed much better than the babbit bearings, differential thermal expansion of the Delrin produced a geometric wedge, and a bearing of this material could not be considered-as a thermal wedge bearing.

description: © 2017 The Author(s). Background: Addressing children's tobacco smoke exposure (TSE) remains a public health priority. However, there is low uptake and ineffectiveness of treatment, particularly in low-income populations that face numerous challenges to smoking behavior change. A multilevel intervention combining system-level health messaging and advice about TSE delivered at community clinics that disseminate the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), combined with nicotine replacement and intensive multimodal, individual-level behavioral intervention may improve TSE control efforts in such high-risk populations. Methods/Design: This trial uses a randomized two-group design with three measurement points: baseline, 3-month and 12-month follow-up. The primary outcome is bioverified child TSE; the secondary outcome is bioverified maternal quit status. Smoking mothers of children less than 6 years old are recruited from WIC clinics. All participants receive WIC system-level intervention based on the "Ask, Advise, Refer (AAR)" best practices guidelines for pediatrics clinics. It includes training all WIC staff about the importance of maternal tobacco control; and detailing clinics with AAR intervention prompts in routine work flow to remind WIC nutrition counselors to ask all mothers about child TSE, advise about TSE harms and benefits of protection, and refer smokers to cessation services. After receiving the system intervention, mothers are randomized to receive 3 months of additional treatment or an attention control intervention: (1) The multimodal behavioral intervention (MBI) treatment includes telephone counseling sessions about child TSE reduction and smoking cessation, provision of nicotine replacement therapy, a mobile app to support cessation efforts, and multimedia text messages about TSE and smoking cessation; (2) The attention control intervention offers equivalent contact as the MBI and includes nutrition-focused telephone counseling, mobile app, and multimedia text messages about improving nutrition. The control condition also receives a referral to the state smoking cessation quitline. Discussion: This study tests an innovative community-based, multilevel and integrated multimodal approach to reducing child TSE in a vulnerable, low-income population. The approach is sustainable and has potential for wide reach because WIC can integrate the tobacco intervention prompts into routine workflow and refer smokers to free evidence-based behavioral counseling interventions, such as state quitlines.

description: BTS special report;6p. in various pagings
description: In 2007, 190 ferry operators across the Nation provided service to an estimated 106 million passengers through nearly 500 terminals in 37 States and 3 U.S. Territories, using a fleet of almost 700 active vessels with capacity to carry as many as 6,000 passengers at a time, or as few as 2. Service was provided on nearly 350 different route segments, covering 7,877 route miles. While the ferry network was somewhat smaller than 2 years earlier, it continued to play an important role providing commuter services in major metropolitan areas on both coasts, offering a vital intercity transportation link between coastal Alaska communities and the lower 48 States, and linking roadways and communities separated by various bodies of water. These are among the findings of the biennial 2008 National Census of Ferry Operators (NCFO), which collects self-reported data from operators of itinerant, regular route ferry services in the United States and its Territories.1 The NCFO collects data on operations during the previous year; thus references in this report to 2007, 2005, and 1999 data refer to the NCFOs conducted in 2008, 2006, and 2000.

description: We have made an extensive study of the magnetic and electrical properties of double-hexagonal closepacked NpPd3 and a range of U(1-x)Np(x)Pd3 compounds with x=0.01, 0.02, 0.05, and 0.50 using magnetization, magnetic susceptibility, electrical resistivity, and heat capacity measurements on polycrystalline samples, performed in the temperature range 2-300 K and in magnetic fields up to 9 T. Two transitions are observed in NpPd3 at T=10 and 30 K. Dilute Np samples (x<0.05) exhibit quadrupolar transitions, with the transition temperatures reduced from those of pure UPd3.

description: © 2017 American Physical Society. We present measurements of elliptic flow (v2) of electrons from the decays of heavy-flavor hadrons (eHF) by the STAR experiment. For Au+Au collisions at sNN=200 GeV we report v2, for transverse momentum (pT) between 0.2 and 7 GeV/c, using three methods: the event plane method (v2{EP}), two-particle correlations (v2{2}), and four-particle correlations (v2{4}). For Au+Au collisions at sNN=62.4 and 39 GeV we report v2{2} for pT<2GeV/c. v2{2} and v2{4} are nonzero at low and intermediate pT at 200 GeV, and v2{2} is consistent with zero at low pT at other energies. The v2{2} at the two lower beam energies is systematically lower than at sNN=200 GeV for pT<1GeV/c. This difference may suggest that charm quarks interact less strongly with the surrounding nuclear matter at those two lower energies compared to sNN=200 GeV.

Wildfire risk and response in Jasper National Park, Alberta: Application of an adaptation readiness framework
Creators: Halabut, Rechelle

Publisher: name: University of Alberta Library
Year: 2021

Environmental change associated with warmer temperatures is creating unprecedented conditions in natural regions and ecosystems. In Jasper National Park, Alberta, climate change, historical fire management practices, and the mountain pine beetle infestation are combining to increase the risk of a major wildfire. The intent of this short commentary is to provide a primer for decision-makers. The application of an adaptation readiness framework highlights areas where the Park’s level of preparedness for wildfire adaptation is well developed and areas in need of further attention. Areas where adaptation is well developed include political leadership, decision making, and stakeholder engagement. Further attention is necessary around institutional organizations, funding, and public support.
Exclusive η electroproduction at W>2 GeV with CLAS and transversity generalized parton distributions

description: © 2017 American Physical Society. The cross section of the exclusive η electroproduction reaction ep→e′p′η was measured at Jefferson Laboratory with a 5.75 GeV electron beam and the CLAS detector. Differential cross sections d4σ/dtdQ2dxBdφη and structure functions σU=σT+ϵσL,σTT, and σLT, as functions of t, were obtained over a wide range of Q2 and xB. The η structure functions are compared with those previously measured for π0 at the same kinematics. At low t, both π0 and η are described reasonably well by generalized parton distributions (GPDs) in which chiral-odd transversity GPDs are dominant. The π0 and η data, when taken together, can facilitate the flavor decomposition of the transversity GPDs.

description: We report the current-perpendicular-to-plane giant magnetoresistance of a spin valve with Co2MnSi (CMS) Heusler alloy ferromagnetic electrodes. A multilayer stack of Cr/Ag/Cr/CMS/Cu/CMS/Fe25Co75/Ir28Mn72/Ru was deposited on a MgO (001) single crystal substrate. The bottom CMS layer was epitaxially grown on the Cr/Ag/Cr buffer layers and was ordered to the L21 structure after annealing at 673 K. The upper CMS layer was found to grow epitaxially on the Cu spacer layer despite the large lattice mismatch between Cu and CMS. The highest MR ratios of 8.6% and 30.7% for CPP-GMR were recorded at room temperature and 6 K, respectively. The high spin polarization of the epitaxial CMS layers is the most likely origin of the high MR ratio.

description: The fundamental energy gap of a periodic solid distinguishes insulators from metals and characterizes low-energy single-electron excitations. However, the gap in the band structure of the exact multiplicative Kohn-Sham (KS) potential substantially underestimates the fundamental gap, a major limitation of KS densityfunctional theory. Here, we give a simple proof of a theorem: In generalized KS theory (GKS), the band gap of an extended system equals the fundamental gap for the approximate functional if the GKS potential operator is continuous and the density change is delocalized when an electron or hole is added. Our theorem explains how GKS band gaps from metageneralized gradient approximations (meta-GGAs) and hybrid functionals can be more realistic than those from GGAs or even from the exact KS potential. The theorem also follows from earlier work. The band edges in the GKS one-electron spectrum are also related to measurable energies. A linear chain of hydrogen molecules, solid aluminum arsenide, and solid argon provide numerical illustrations.

description: The two-phase free boundary problem for the Navier-Stokes system is considered in a situation where the initial interface is close to a halfplane. By means of $L_p$-maximal regularity of the underlying linear problem we show local well-posedness of the problem, and prove that the solution, in particular the interface, becomes instantaneously real analytic.

description: This paper is concerned with distributed limited memory prediction for continuous-time linear stochastic systems with multiple sensors. A distributed fusion with the weighted sum structure is applied to the optimal local limited memory predictors. The distributed prediction algorithm represents the optimal linear fusion by weighting matrices under the minimum mean square criterion. The algorithm has the parallel structure and allows parallel processing of observations making it reliable since the rest faultless sensors can continue to the fusion estimation if some sensors occur faulty. The derivation of equations for error cross-covariances between the local predictors is the key of this paper. Example demonstrates effectiveness of the distributed limited memory predictor.

Critical Casimir force in slab geometry with finite aspect ratio: analytic calculation above and below $T_c$

description: We present a field-theoretic study of the critical Casimir force of the Ising universality class in a $d$-dimensional ${L_\parallel^{d-1} \times L}$ slab geometry with a finite aspect ratio $ρ= L/L_\parallel$ above, at, and below $T_c$. The result of a perturbation approach at fixed dimension $d=3$ is presented that describes the dependence on the aspect ratio in the range $ρ\gtrsim 1/4$. Our analytic result for the Casimir force scaling function for $ρ= 1/4$ agrees well with recent Monte Carlo data for the three-dimensional Ising model in slab geometry with periodic boundary conditions above, at, and below $T_c$.
