description: We study the stellar and gas kinematics of the brightest group galaxies (BGGs) in dynamically relaxed and unrelaxed galaxy groups for a sample of 154 galaxies in the SAMI galaxy survey. We characterize the dynamical state of the groups using the luminosity gap between the two most luminous galaxies and the BGG offset from the luminosity centroid of the group. We find that the misalignment between the rotation axis of gas and stellar components is more frequent in the BGGs in unrelaxed groups, although with quite low statistical significance. Meanwhile galaxies whose stellar dynamics would be classified as `regular rotators' based on their kinemetry are more common in relaxed groups. We confirm that this dependency on group dynamical state remains valid at fixed stellar mass and Sersic index. The observed trend could potentially originate from a differing BGG accretion history in virialised and evolving groups. Amongst the halo relaxation probes, the group BGG offset appears to play a stronger role than the luminosity gap on the stellar kinematic differences of the BGGs. However, both the group BGG offset and luminosity gap appear to roughly equally drive the misalignment between the gas and stellar component of the BGGs in one direction. This study offers the first evidence that the dynamical state of galaxy groups may influence the BGG's stellar and gas kinematics and calls for further studies using a larger sample with higher signal-to-noise.

description: Using the O(a) Symanzik improved action an estimate is given for the strange quark mass for unquenched (n_f=2) QCD. The determination is via the axial Ward identity (AWI) and includes a non-perturbative evaluation of the renormalisation constant. Numerical results have been obtained at several lattice spacings, enabling the continuum limit to be taken. Our results indicate a value for the strange quark mass (in the MS-bar scheme at a scale of 2 GeV) in the range 100 - 130 MeV. A comparison is also made with other recent lattice determinations of the strange quark mass using dynamical sea quarks.

description: HD~69479/80 is a composite-spectrum binary whose components are a late-G giant and an early-A dwarf. The orbit has a period of only 91 days (which seems short for a system containing a cool giant with a radius of $\sim$13 solar radii), and a very small, but probably significantly non-zero, eccentricity. We separated the component spectra by a procedure of spectral subtraction, using a standard single giant spectrum as a template, and found the closest match to the spectrum of the cool component to be that of 15~Cyg (G8\,III). We measured the radial velocity of the secondary component from each uncovered spectrum, solved the SB2 orbit for the system, and derived a mass ratio $m_1$\,/\,$m_2$ of 1.318. Fitting synthetic spectra to the spectra of the secondary component indicated a \teff~of 9250\,K, {\it log}\,g = 3.75, and a rotational velocity of $\sim$90\,\kms. We determined the difference in absolute magnitude, $δ$V, between the component stars to be 1.07 mag, the late-type component being the brighter; we could thence calculate radii and luminosities for both components, plot their H--R diagram positions, and fit evolutionary tracks. The best-fitting tracks indicated masses of 2.9\,\msun~for the giant and 2.2\,\msun~for the dwarf, which was fully in keeping with the mass ratio given by the SB2 orbit. The track for the dwarf star confirms that this component has begun to evolve away from the ZAMS. Fitting the corresponding isochrone to those H--R diagram positions indicated a log\,(age) of the system of approximately 8.60 Gyr since the cool star evolved from the ZAMS, which is a little younger than the ages deduced for many cool giants. We also detected the $λ$\,6707-Å~lithium line in the spectrum of the giant component, thus adding to the evidence that it is near the start of its primary ascent of the red-giant branch.

description: Abstract

Production planning is a problem at CV. Pandu Kencana Jombang, where the production quantity of Timba Cor TC is not planned ahead of the production process but is instead determined statically or based on warehouse stock without considering sales dynamics. The author proposes a solution by implementing the Triple Exponential Smoothing forecasting method. This well-known adaptive method is used for time series modeling and involves three levels of smoothing: overall, trend, and seasonal smoothing. Before forecasting the production and sales of TC Cor Lead for Week 1 of April 2022, an alpha value with the smallest error percentage is required. To find this, data from August 2021 to March 2022 is used for forecasting, applying alpha values from 0.1 to 0.9, and calculating the MAPE (mean absolute percentage error) for each. Once the alpha with the smallest MAPE is found, it is used to predict Week 1 of April 2022. The study results show that the Triple Exponential Smoothing method successfully predicted the production and sales with 97.7% accuracy and a 6.3% MAPE for production, and 93.7% accuracy with a 6.3% MAPE for sales.

Interaction of near-inertial waves with an anticyclonic vortex

description: Anticyclonic vortices focus and trap near-inertial waves so that near-inertial energy levels are elevated within the vortex core. Some aspects of this process, including the nonlinear modification of the vortex by the wave, are explained by the existence of trapped near-inertial eigenmodes. These vortex eigenmodes are easily excited by an initial wave with horizontal scale much larger than that of the vortex radius. We study this process using a wave-averaged model of near-inertial dynamics and compare its theoretical predictions with numerical solutions of the three-dimensional Boussinesq equations. In the linear approximation, the model predicts the eigenmode frequencies and spatial structures, and a near-inertial wave energy signature that is characterized by an approximately time-periodic, azimuthally invariant pattern. The wave-averaged model represents the nonlinear feedback of the waves on the vortex via a wave-induced contribution to the potential vorticity that is proportional to the Laplacian of the kinetic energy density of the waves. When this is taken into account, the modal frequency is predicted to increase linearly with the energy of the initial excitation. Both linear and nonlinear predictions agree convincingly with the Boussinesq results.

description: JEDI (Joint Efficient Dark-energy Investigation) is a candidate implementation of the NASA-DOE Joint Dark Energy Mission (JDEM). JEDI will probe dark energy in three independent methods: (1) type Ia supernovae, (2) baryon acoustic oscillations, and (3) weak gravitational lensing. In an accompanying paper, an overall summary of the JEDI mission is given. In this paper, we present further details of the supernova component of JEDI. To derive model-independent constraints on dark energy, it is important to precisely measure the cosmic expansion history, H(z), in continuous redshift bins from z \~ 0-2 (the redshift range in which dark energy is important). SNe Ia at z > 1 are not readily accessible from the ground because the bulk of their light has shifted into the near-infrared where the sky background is overwhelming; hence a space mission is required to probe dark energy using SNe. Because of its unique near-infrared wavelength coverage (0.8-4.2 microns), JEDI has the advantage of observing SNe Ia in the rest frame J band for the entire redshift range of 0 < z < 2, where they are less affected by dust, and appear to be nearly perfect standard candles. During the first year of JEDI operations, spectra and light curves will be obtained for ~4,000 SNe Ia at z < 2. The resulting constraints on dark energy are discussed, with special emphasis on the improved precision afforded by the rest frame near-infrared data.

On the incidence rate of first overtone Blazhko stars in the Large Magellanic Cloud

description: By using the full span of multicolor data on a representative sample of first overtone RR Lyrae stars in the Large Magellanic Cloud (LMC) we revisit the problem of the incidence rate of the amplitude/phase-modulated (Blazhko) stars. Multicolor data, obtained by the MAssive Compact Halo Objects (MACHO) project, are utilized through a periodogram averaging method. This enables us to increase the number of detected multiperiodic variables by 18% relative to the number obtained by the analysis of the best single color data. We also test the maximum modulation period detectable in the present dataset. We find that variables showing amplitude/phase modulations with periods close to the total time span can still be clearly separated from the class of stars showing period changes. This larger limit on the modulation period, the more efficient data analysis and the longer time span lead to a substantial increase in the incidence rate of the Blazhko stars in comparison with earlier results. We find altogether 99 first overtone Blazhko stars in the full sample of 1332 stars, implying an incidence rate of 7.5%. Although this rate is nearly twice of the one derived earlier, it is still significantly lower than that of the fundamental mode stars in the LMC. The by-products of the analysis (e.g., star-by-star comments, distribution functions of various quantities) are also presented.

description: This thesis covers the development of a motion tracking instrument geared towards the needs of the geohazard community. Currently, there are no low cost instrument packages well suited for detecting and tracking geophysical flows. Therefore, a lack of scientific data exists surrounding the flow paths and characteristics of flows such as landslides. The goal of this thesis is the creation of an inertial tracking system to be combined with a commercial radio frequency distance measuring system in order to fill the needs of the scientific community. The instrument developed herein is comprised of a three-axis MEMS accelerometer, a two-axis solid state tilt sensor, and two-axis magnetic compass module. To improve upon the accuracy of the inertial tracking system, a dynamic bias correction method has been developed. To evaluate the instrument and determine the effectiveness of the dynamic bias correction method, a five-axis test platform was developed to simulate geophysical flows. Results from the tests show that new drift correction method keeps velocity and displacement from diverging uncontrollably due to accelerometer bias drift. In tests, this correction method reduced the static accelerometer drift by 99%, and the dynamic accelerometer drift by a minimum of 43%. The resulting dynamic errors range in value from 1.07-10.4% of the total distance traveled.

description: The ability to predict responses caused by changes in production input factors is an important management strategy. When used for this purpose, response simulation models can have useful roles to play especially in the field of animal production. The Edinburgh Poultry Growth Model was developed with the objective of assisting the poultry nutritionist, breeder, adviser and poultry farmer in the making of management decisions in the areas of poultry growth, with special reference to broiler production processes, from the important variables of nutrition, genotype, temperature and husbandry. An attempt has been made in this dissertation to test the Edinburgh Poultry Growth Model and to critically assess its theoretical features and performance. The model was found to possess great potential in fulfilling the stated objectives. The responses from the majority of the variables were consistent with those found in the existing research literature. It was found to be highly flexible and stable in coping with all the variables. However, the model is at present too sensitive in its temperature aspects. The assumptions made to formulate the equations for the heat loss mechanism are not yet adequate for simulating the thermoregulatory activities of poultry. It is believed that the problem is due to an absence in the existing state of knowledge, of appropriate data which could incorporate the behavioural responses to temperature in animals under ad libitum feeding systems. If this aspect of the model could be improved upon, it would enhance its value as a computer program in the fields of poultry production, research and teaching.

description: The dispersion of the Cu-O bond-stretching vibrations in overdoped La$_{1.7}$Sr$_{0.3}$CuO$_4$ (not superconducting) has been studied by high resolution inelastic neutron scattering. It was found that the doping-induced renormalization of the so-called breathing and the half-breathing modes is larger than in optimally doped La$_{1.85}$Sr$_{0.15}$CuO$_4$. On the other hand, the phonon linewidths are generally smaller in the overdoped sample. Features observed in optimally doped La$_{1.85}$Sr$_{0.15}$CuO$_4$ which suggest a tendency towards charge stripe formation are absent in overdoped La$_{1.7}$Sr$_{0.3}$CuO$_4$.

Employing a phase dithering mechanism for the different beams similar to LOCSET, dithering frequencies for sequential combination steps are reused. By applying an additional phase alternating scheme, this allows to use standard synchronized multichannel lock-in electronics for phase locking a large number of channels even when the frequency bandwidth of the employed phase actuators is limited.

description: Through its incorporation and release from polymeric matrices in the oral environment, amorphous calcium phosphate (ACP) has shown the potential to support the remineralization of tooth enamel. However, the highly agglomerative nature of as-made ACP filler particles prevents a simple optimization of the physical, chemical and mechanical properties of composites in which they are incorporated. In this study, as-made and milled ACP composites were compared in a number of physicochemical and mechanical categories. In addition, a test fixture was developed that allows the cyclic loading of specimens previously tested only monotonically, providing a more clinically relevant method of characterizing the composite-adhesive-dentin bond. A preliminary investigation was performed to characterize the fatigue response of bonded TPH composites. Elimination of the large agglomerates in as-made ACP allowed for a 50% higher fill level in milled ACP composites, with a corresponding 50% reduction in shrinkage stress over as-made ACP composites. The mean biaxial flexure strength of milled ACP did not significantly deteriorate after 1 month of saline immersion (p<0.001), and were significantly stronger than as-made ACP composites after 3 months (p<0.001). As-made ACP composites absorbed significantly more water (p<0.001), and released significantly higher amounts of calcium and phosphate than milled ACP composites after 3 months immersion (p?0.025). In an evaluation of shear bond strength, milled ACP composites produced a higher incidence of the failure mode consistent with stronger adhesion, and exhibited a mechanical response within aqueous immersion more akin to glass-reinforced composites than to those containing as-made ACP. The bonded TPH composites tested in fatigue did not exhibit an obvious endurance strength. Instead, the shear bond fatigue strength test method was seen to provide an indirect measure of the flaws present in the adhesive layer and the tooth structure.

description: Investigating the dust heating mechanisms in galaxies provides a deeper understanding of how the internal energy balance drives their evolution. Over the last decade, radiative transfer simulations based on the Monte Carlo method have underlined the role of the various stellar populations heating the diffuse dust. Beyond the expected heating through ongoing star formation, both older stellar population (> 8Gyr) and even AGN can contribute energy to the infrared emission of diffuse dust. Here, we examine how the radiation of an external heating source, like the less massive galaxy NGC5195, in the M51 interacting system, could affect the heating of the diffuse dust of its parent galaxy, NGC5194, and vice versa. To quantify the exchange of energy between the two galaxies we use SKIRT, a state-of-the-art Monte Carlo radiative transfer code. In the interest of modelling, the assumed centre-to-centre distance separation between the two galaxies is 10kpc. Our model reproduces the global SED of the system, and it closely matches the observed images. In total, 40.7% of the intrinsic stellar radiation of the combined system is absorbed by dust. Furthermore, we quantify the contribution of the various dust heating sources in the system, and find that the young stellar population of NGC5194 is the predominant dust-heating agent, with a global heating fraction of 71.2%. Another 23% is provided by the older stellar population of the same galaxy, while the remaining 5.8% has its origin in NGC5195. Locally, we find that the regions of NGC5194 closer to NGC5195 are significantly affected by the radiation field of the latter, with the absorbed energy fraction rising up to 38%. The contribution of NGC5195 remains under the percentage level in the outskirts of the disc of NGC5194. This is the first time that the heating of the diffuse dust by a companion galaxy is quantified in a nearby interacting system.

description: Transmission electron microscopy (TEM) of vitrified biological macromolecules (cryo-EM) is limited by the weak phase contrast signal that is available from such samples. Using a phase plate would thus substantially improve the signal-to-noise ratio. We have previously demonstrated the use of a high-power Fabry-Perot cavity as a phase plate for TEM. We now report improvements to our laser cavity that allow us to achieve record continuous-wave intensities of over 450 GW/cm$^{2}$, sufficient to produce the optimal 90° phase shift for 300 keV electrons. In addition, we have performed the first cryo-EM reconstruction using a laser phase plate, demonstrating that the stability of this laser phase plate is sufficient for use during standard cryo-EM data collection.

description: The role of photovoltaics in the energy industry has become well known over the course of the past decade.  One new method of manufacturing silicon solar cells is using the ribbon growth on substrate process (RGS). The contact resistance between the silicon and the substrate plays a critical role in the efficiency of the silicon wafer. A model for prediction the contact resistance at the solid-liquid interface for RGS process is created based on a discrete surface model and heat transfer model. The effect of radiation on the contact resistance is quantified for various surface and material properties and operational conditions.  The model result without radiation is found to be consistent those obtained through analytical experimental study. Radiation is found to increase the heat transfer for substrates of rough surface and low thermal conductivity.  Other parameters such as surface emissivity, melt temperature, and substrate temperature are also studied. It is found that these parameters have a moderate effect on the heat transfer coefficient. On the other hand, substrate surface roughness and thermal conductivity are prominent factors in heat transfer at the interface.  A full model of RGS process is used to characterize the effect of contact resistance on the heat removed from the interface by the substrate. For typical surface and material properties, contact resistance is able to cause a substantial temperature drop at the solid-liquid interface. The effect of contact resistance on heat transfer at the interface for substrates of different materials and different pulling rates is also studied.

description: Type Ia supernovae (SNe Ia) are the largest thermonuclear explosions in the Universe. Their light output can be seen across great distances and has led to the discovery that the expansion rate of the Universe is accelerating. Despite the significance of SNe Ia, there are still a large number of uncertainties in current theoretical models. Computational modeling offers the promise to help answer the outstanding questions. However, even with today's supercomputers, such calculations are extremely challenging because of the wide range of length and time scales. In this paper, we discuss several new algorithms for simulations of SNe Ia and demonstrate some of their successes.

description: Hemodialysis (HD) is known to affect ocular blood flow. This case-control study aims to evaluate macular and peripapillary vasculature in patients with end-stage renal disease (ESRD) receiving HD in comparison to matched controls. A total of 24 eyes of 24 ESRD patients receiving HD and 24 eyes of 24 healthy, age- and gender-matched control subjects were prospectively included in this study. Optical coherence tomography angiography was used to image the superficial (SCP), deep (DCP), and choriocapillary (CC) macular vascular plexus, as well as the radial peripapillary capillaries (RPC) of the optic disc. In addition, retinal thickness (RT) and retinal volume (RV) were compared between both groups. Flow density (FD) values of each retinal layer and data of parameters related to the foveal avascular zone (FAZ), as well as RT and RV, were analyzed using Mann–Whitney U tests. There was no significant difference in FAZ parameters between the two groups. Whole en face FD of the SCP and CC was noticeably reduced in the HD group in comparison to the control group. FD was negatively correlated with the duration of HD treatment. RT and RV were significantly smaller in the study group than in controls. Retinal microcirculation appears altered in patients with ESRD undergoing HD. Concurrently, the DCP appears more resilient towards hemodynamic changes in comparison to the other microvascular retinal layers. OCTA is a useful, non-invasive tool to investigate retinal microcirculation in ESRD patients.

description: Localized basis sets in the projector augmented wave formalism allow for computationally efficient calculations within density functional theory (DFT). However, achieving high numerical accuracy requires an extensive basis set, which also poses a fundamental problem for the interpretation of the results. We present a way to obtain a reduced basis set of atomic orbitals through the subdiagonalization of each atomic block of the Hamiltonian. The resulting local orbitals (LOs) inherit the information of the local crystal field. In the LO basis, it becomes apparent that the Hamiltonian is nearly block-diagonal, and we demonstrate that it is possible to keep only a subset of relevant LOs which provide an accurate description of the physics around the Fermi level. This reduces to some extent the redundancy of the original basis set, and at the same time it allows one to perform post-processing of DFT calculations, ranging from the interpretation of electron transport to extracting effective tight-binding Hamiltonians, very efficiently and without sacrificing the accuracy of the results.

description: We report measurements of the cross-section and a complete set of polarization transfer coefficients for the ${}^{3}{\rm He}(p,n)$ reaction at a bombarding energy $T_p$ = 346 MeV and a reaction angle $θ_{\rm lab}$ = $0^{\circ}$. The data are compared with the corresponding free nucleon-nucleon values on the basis of the predominance of quasi-elastic scattering processes. Significant discrepancies have been observed in the polarization transfer $D_{LL}(0^{\circ})$, which are presumably the result of the three-proton $T$ = 3/2 resonance. The spin--parity of the resonance is estimated to be $1/2^-$, and the distribution is consistent with previous results obtained for the same reaction at $T_p$ = 48.8 MeV.

description: In this work we have studied the QCD phase structure and critical dynamics related to the 3-$d$ $O(4)$ and $Z(2)$ symmetry universality classes in the two-flavor quark-meson low energy effective theory within the functional renormalization group approach. We have employed the expansion of Chebyshev polynomials to solve the flow equation for the order-parameter potential. The chiral phase transition line of $O(4)$ symmetry in the chiral limit, and the $Z(2)$ line of critical end points related to the explicit chiral symmetry breaking are depicted in the phase diagram. Various critical exponents related to the order parameter, chiral susceptibilities and correlation lengths have been calculated for the 3-$d$ $O(4)$ and $Z(2)$ universality classes in the phase diagram, respectively. We find that the critical exponents obtained in the computation, where a field-dependent mesonic nontrivial dispersion relation is taken into account, are in quantitative agreement with results from other approaches, e.g., the conformal bootstrap, Monte Carlo simulations and $d=3$ perturbation expansion, etc. Moreover, the size of the critical regime in the QCD phase diagram is found to be very small.

description: The problem of the flux to a spherical trap in one and three dimensions, for diffusing particles undergoing discrete-time jumps with a given radial probability distribution, is solved in general, verifying the Smoluchowski-like solution in which the effective trap radius is reduced by an amount proportional to the jump length. This reduction in the effective trap radius corresponds to the Milne extrapolation length.

description: We here introduce an automatic Digital Terrain Model (DTM) extraction method. The proposed sparsity-driven DTM extractor (SD-DTM) takes a high-resolution Digital Surface Model (DSM) as an input and constructs a high-resolution DTM using the variational framework. To obtain an accurate DTM, an iterative approach is proposed for the minimization of the target variational cost function. Accuracy of the SD-DTM is shown in a real-world DSM data set. We show the efficiency and effectiveness of the approach both visually and quantitatively via residual plots in illustrative terrain types.

A New Dynamic Stability Theory for Distributed Structural Systems with Periodically Varying Parameters

Publisher: name: Maryland Shared Open Access Repository
Year: 2008
Subjects: Engineering, Mechanical (0548)

description: A new method for determining the exact parametric instability regions of a class of second-order distributed structural (or hyperbolic) systems with periodically varying parameters is developed. The method is based on the non-dispersive wave behavior of a distributed system, and the conditions for the existence of such non-dispersive wave behavior are presented. Several example systems are considered, including a translating string with constant length and periodically varying velocity, a translating string with periodically varying length, a stationary string with one or two periodically moving boundaries, and a translating string with a periodically varying tension. The parametric instabilities of these systems are characterized by bounded displacements, exponentially growing vibratory energies, and formation of shock waves. The period-1 instability regions in a parameter plane are obtained analytically using the new wave method and the concept of a fixed point. A general formulation for calculating the period-i (i>1) instability regions is given. The bifurcation diagram is introduced for calculating the period-i (i>1) instability regions numerically. The basins of attraction for period-1 attracting fixed points are obtained analytically and a physical explanation of shock wave instabilities is provided using wave propagation. The dynamic response of a translating string with constant length and arbitrarily varying length is obtained using an exact wave method, real and complex modal analyses, and an implicit finite difference scheme. The least upper bound of the displacement of the freely vibrating string is obtained for an arbitrary movement profile. A numerical damping term is added to stabilize the finite difference scheme when the system has shock wave instability. The Floquet-Liapunov theorem is used to calculate the eigenvalues of a transition matrix for dynamic systems with periodically varying parameters. A numerical method is provided for approximating the periodic transition matrix in one period using step functions. The instability regions of a translating string with constant length and periodically varying velocity are obtained using the numerical method. The effects of the number of spatial discretization terms on the prediction of the parametric instability regions are discussed. The effects of damping, tension variation, the constant part of the velocity, and the real and complex trial functions on the instability regions predicted are also discussed for the same system.

description: In this study Dynamic Mechanical Anlaysis (DMA) was applied to dentin, the macro hybrid layer and intact hybrid layers of the bonded dental restorative interface using nanoindentation.  Both intertubular and peritubular dentin were evaluated by DMA using discrete and scanning mode nanoindentation. The complex (E*), loss (E), and storage (E') moduli were quantified over a range of indentation loads and scanning frequencies. The storage modulus of the peritubular cuff (22.19 GPa0.05). A model bonded interface (i.e. the macro hybrid) was evaluated using scanning DMA.  A new approach for hydrating samples using ethylene glycol solution was developed and then applied to identify the importance of hydration on the measured properties.  Fully hydrated samples exhibited mean values of E*, E' and E of 3.54 GPa, 3.42 GPa and 0.86 GPa, respectively, whereas fully dehydrated samples exhibited values of 4.01 GPa, 3.88 GPa and 0.94 GPa, respectively. There were significant differences in the complex modulus (p<0.05) and storage modulus (p<0.001) between the hydrated and dehydrated conditions. However, differences in the loss moduli with hydration were not significantly different (p>0.05). A dynamic loading frequency of 100 Hz and scanning frequency of 0.2 Hz were identified to provide the most reliable results in scanning the collagen-based systems. Lastly, the optimal testing parameters obtained from studying the macro hybrid layer were used to evaluate intact resin-dentin bonded interfaces.  The property maps clearly distinguished variations in properties as a function of the constituents.  It was identified that scanning based nanoDMA is a potent tool for evaluating mechanical properties of the hybrid layer but testing parameters and maintenance of the hydration are critical to the interpretation of apparent mechanical behavior.
