description: The preservation of stochastic orders by distortion functions has become a topic of increasing interest in the reliability analysis of coherent systems. The reason of this interest is that the reliability function of a coherent system with identically distributed components can be represented as a distortion function of the common reliability function of the components. In this framework, we study the preservation of the excess wealth order, the total time on test transform order, the decreasing mean residual live order, and the quantile mean inactivity time order by distortion functions. The results are applied to study the preservation of these stochastic orders under the formation of coherent systems with exchangeable components.

description: We argue that quintessence may reside in certain corners of the string landscape. It arises as a linear combination of internal space components of higher rank forms, which are axion-like at low energies, and may mix with 4-forms after compactification of the Chern-Simons terms to 4D due to internal space fluxes. The mixing induces an effective mass term, with an action which {\it preserves} the axion shift symmetry, breaking it spontaneously after the background selection. With several axions, several 4-forms, and a low string scale, as in one of the setups already invoked for dynamically explaining a tiny residual vacuum energy in string theory, the 4D mass matrix generated by random fluxes may have ultralight eigenmodes over the landscape, which are quintessence. We illustrate how this works in simplest cases, and outline how to get the lightest mass to be comparable to the Hubble scale now, $H_0 \sim 10^{-33} {\rm eV}$. The shift symmetry protects the smallest mass from perturbative corrections in field theory. Further, if the ultralight eigenmode does not couple directly to any sector strongly coupled at a high scale, the non-perturbative field theory corrections to its potential will also be suppressed. Finally, if the compactification length is larger than the string length by more than an order of magnitude, the gravitational corrections may remain small too, even when the field value approaches $M_{Pl}$.

description: Recent developments in the field of mobile application and transport have heightened the need for efficient energy storage systems. Batteries are the most widespread energy storage systems for powering portable electronic devices and electric vehicles. Between them, the most used type of battery is Lithium-ion batteries. 3D printing of Li-ion batteries also known as secondary type batteries received vast recognition for advancing the next generation of 3D energy storage devices. Printing technologies offer simple processing and low-cost manufacturing, resulting in the potential replacement of conventional technologies. This thesis project is focused on the synthesis of a printable polymer-based electrolyte for Li-ion battery with a relative study of the 3D printing process, electrochemical and thermal properties of the electrolyte. The Poly (vinylidene fluoride-hexafluoropropylene) matrices and a Li+-conducting ionic-liquid salt are components of the hybrid polymer-based electrolyte developed in this study. To attain the desired rheological qualities of the electrolyte solution and improve the thermal properties of the electrolyte, the electrolyte ink composition was modified by adding Silane Boron-Nitride nanosized ceramic filler. Once verified the effective printability of the ink, a detailed analysis of the influence of the 3D printing machine dispensing parameters on the final printed structure was conducted. The overpotential and cyclability tests, performed to characterize the electrochemical properties, revealed interesting performances of the printed polymer electrolyte. Finally, the electrolyte enhanced thermal properties were demonstrated with a direct comparison between the 3D printed polymer electrolyte and a common liquid electrolyte. Nevertheless, further studies regarding the safety of the electrolyte can help to better understand the thermal runaway mechanism and serve as a source of inspiration for future work.

description: New parameterizations for the spectra dissipation of wind-generated waves are proposed. The rates of dissipation have no predetermined spectral shapes and are functions of the wave spectrum and wind speed and direction, in a way consistent with observation of wave breaking and swell dissipation properties. Namely, the swell dissipation is nonlinear and proportional to the swell steepness, and dissipation due to wave breaking is non-zero only when a non-dimensional spectrum exceeds the threshold at which waves are observed to start breaking. An additional source of short wave dissipation due to long wave breaking is introduced to represent the dissipation of short waves due to longer breaking waves. Several degrees of freedom are introduced in the wave breaking and the wind-wave generation term of Janssen (J. Phys. Oceanogr. 1991). These parameterizations are combined and calibrated with the Discrete Interaction Approximation of Hasselmann et al. (J. Phys. Oceangr. 1985) for the nonlinear interactions. Parameters are adjusted to reproduce observed shapes of directional wave spectra, and the variability of spectral moments with wind speed and wave height. The wave energy balance is verified in a wide range of conditions and scales, from gentle swells to major hurricanes, from the global ocean to coastal settings. Wave height, peak and mean periods, and spectral data are validated using in situ and remote sensing data. Some systematic defects are still present, but the parameterizations yield the best overall results to date. Perspectives for further improvement are also given.

Inverse quantum spin Hall effect generated by spin pumping from precessing magnetization into a graphene-based two-dimensional topological insulator

description: We propose a multiterminal nanostructure for electrical probing of the quantum spin Hall effect (QSHE) in two-dimensional (2D) topological insulators. The device consists of a ferromagnetic (FM) island with precessing magnetization that pumps (in the absence of any bias voltage) pure spin current symmetrically into the left and right adjacent 2D TIs modeled as graphene nanoribbons with the intrinsic spin-orbit (SO) coupling. The QSH regime of the six-terminal TI|FM|TI nanodevice, attached to two longitudinal and four transverse normal metal electrodes, is characterized by the SO-coupling-induced energy gap, chiral spin-filtered edge states within finite length TI regions, and quantized spin Hall conductance when longitudinal bias voltage is applied, despite the presence of the FM island. The same unbiased device, but with precessing magnetization of the central FM island, blocks completely pumping of total spin and charge currents into the longitudinal electrodes while generating DC transverse charge Hall currents. Although these transverse charge currents are not quantized, their induction together with zero longitudinal charge current is a unique electrical response of TIs to pumped pure spin current that cannot be mimicked by SO-coupled but topologically trivial systems. In the corresponding two-terminal inhomogeneous TI|FM|TI nanostructures, we image spatial profiles of local spin and charge currents within TIs which illustrate transport confined to chiral spin-filtered edges states while revealing concomitantly the existence of interfacial spin and charge currents flowing around TI|FM interfaces and penetrating into the bulk of TIs over some short distance.

description: We have proposed an exactly solvable quantum spin-3/2 model on a square lattice. Its ground state is a quantum spin liquid with a half integer spin per unit cell. The fermionic excitations are gapless with a linear dispersion, while the topological "vison" excitations are gapped. Moreover, the massless Dirac fermions are stable. Thus, this model is, to the best of our knowledge, the first exactly solvable model of half-integer spins whose ground state is an "algebraic spin liquid."

description: We present first principles calculations of current-voltage characteristics (IVC) and conductance of Au(111):S2-cumulene-S2:Au(111) molecular wire junctions with realistic contacts. The transport properties are calculated using full self-consistent ab initio NEGF-DFT methods under external bias. The conductance of the cumulene wires shows oscillatory behavior depending on the number of carbon atoms (double bonds). Among all conjugated oligomers, we find that cumulene wires with odd number of carbon atoms yield the highest conductance with metallic-like ballistic transport behavior. The reason is the high density of states in broad LUMO levels spanning the Fermi level of the electrodes. The transmission spectrum and the conductance depend only weakly on applied bias, and the IVC is nearly linear over a bias region from +1 to -1 V. Cumulene wires are therefore potential candidates for metallic connections in nanoelectronic applications.

description: We investigate test particle trajectories in warped spacetimes with a thick brane warp factor, a cosmological on--brane line element and a time dependent extra dimension. The geodesic equations are reduced to a first order autonomous dynamical system. Using analytical methods, we arrive at some useful general conclusions regarding possible trajectories. Oscillatory motion, suggesting confinement about the location of the thick brane, arises for a growing warp factor. On the other hand, we find runaway trajectories (exponential-like) for a decaying warp factor. Variations of the extra dimensional scale factor yield certain quantitative differences. Results obtained from explicit numerical evaluations match well with the qualitative conclusions obtained from the dynamical systems analysis.

description: This paper introduces a speech enhancement solution tailored for true wireless stereo (TWS) earbuds on-device usage. The solution was specifically designed to support conversations in noisy environments, with active noise cancellation (ANC) activated. The primary challenges for speech enhancement models in this context arise from computational complexity that limits on-device usage and latency that must be less than 3 ms to preserve a live conversation. To address these issues, we evaluated several crucial design elements, including the network architecture and domain, design of loss functions, pruning method, and hardware-specific optimization. Consequently, we demonstrated substantial improvements in speech enhancement quality compared with that in baseline models, while simultaneously reducing the computational complexity and algorithmic latency.

On the feasibility of incorporating the mass concept into conformally invariant action principles
Creators: name: Drew, Mark Samuel
Publisher: name: University of British Columbia
Year: 2010

description: Following an examination of the properties of the conformal group in 4-space, a review is made of the procedure by which conformally covariant massless field equations are written in manifestly covariant form. By writing the Minkowski coordinates in terms of coordinates on the null hyperquadric of a 6-dimensional flat space with two timelike directions, the action of the group is linearized and field equations are written in rotationally covariant form in 6-dimensional space. It is then shown that extending the 6-coordinates off the null surface generalizes Minkowski space to a 5-dimensional space. Such a generalization necessitates employing a method of descent to 4-dimensional space from six dimensions which differs from the usual procedure, and allows one to encompass massive field theories in the manifest formalism. It is demonstrated that these massive fields can be understood as manifestations in Minkowski space of massless fields in 5-dimsnsional space. For the case of spinors, the field equation can accomodate precisely two species of particle having two different masses. An action principle is developed in the 6-space, and a method of field quantization is devised. As examples of the method, the special cases of spin-0, spin-1/2, and spin-1 fields are examined in detail, and minimal coupling of the spinor field equation is carried out. The formalism presented in this investigation provides a means by which one can apprehend a massive compensating field within the confines of a gauge invariant theory. The interactions which are obtained in Minkowski space include not only the usual couplings with massive vector or pseudovector fields, but as well the pseudoscalar coupling occurs automatically within this gauge invariant formulation.

Detection of Fatigue Crack in Metallic Structures with In-Situ Phased Array Ultrasonics
Creators: name: Rakovic, Tanja
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Much of the world’s infrastructure is made from metal. These structures are subject to cyclic loads which can eventually cause the formation of micro-cracks. This would be considered as stage 1, the initiation stage, of the fatigue crack propagation process. Further loading increases the fatigue crack size as it enters stage 2, the propagation stage. If no action is taken the crack becomes so large that failure occurs at stage 3, the fracture stage. Therefore, it is important to detect fatigue cracks before they become too large and cause destruction by employing structural health monitoring methods like ultrasonic testing. Damage indices extracted from ultrasonic signals have been used in the literature to characterize and locate damage. They were based on amplitude and energy of the ultrasonic signals in the time domain and frequency domain, as well as fusions of multiple damage indices. In this research, a guided wave ultrasonic in phase array was used to detect a fatigue crack in-situ in a modified ASTM E647 compact tension specimen, where the crack was designed to grow at the notch tip. A numerical model was created in COMSOL Multiphysics to confirm the formation of the crack at the notch tip first. Dynamic models were also created at frequencies of 400 and 300 kHz to extract the signals needed for the damage index calculations based on amplitude, energy, frequency and phase shift. The experimental study transmitted ultrasonic signals at 400 and 300 kHz to the structural steel specimen after the crack grew at each 10,000 cycle interval. A new damage index using the surface wave arrival as the reference signal was introduced. The damage indices were calculated and compared to the numerical results to determine the most effective damage index for tracking the progress of the fatigue crack. DIs for receivers closest to the transmitter based on amplitude, energy, frequency and phase shift were effective at 400 kHz within the time range of the expected crack reflection.

description: The [CII] 158$μ$m fine-structure line is the dominant cooling line of moderate-density photodissociation regions (PDRs) illuminated by moderately bright far-ultraviolet (FUV) radiation fields. We aim to understand the origin of [CII] emission and its relation to other tracers of gas and dust in PDRs. One focus is a study of the heating efficiency of interstellar gas as traced by the [CII] line to test models of the photoelectric heating of neutral gas by polycyclic aromatic hydrocarbon (PAH) molecules and very small grains. We make use of a one-square-degree map of velocity-resolved [CII] line emission toward the Orion Nebula complex, and split this out into the individual spatial components, the expanding Veil Shell, the surface of OMC4, and the PDRs associated with the compact HII region of M43 and the reflection nebula NGC 1977. We employed Herschel far-infrared photometric images to determine dust properties. Moreover, we compared with Spitzer mid-infrared photometry to trace hot dust and large molecules, and velocity-resolved IRAM 30m CO(2-1) observations of the molecular gas. The [CII] intensity is tightly correlated with PAH emission in the IRAC 8$μ$m band and far-infrared emission from warm dust. The correlation between [CII] and CO(2-1) is very different in the four subregions and is very sensitive to the detailed geometry. Constant-density PDR models are able to reproduce the observed [CII], CO(2-1), and integrated far-infrared (FIR) intensities. We observe strong variations in the photoelectric heating efficiency in the Veil Shell behind the Orion Bar and these variations are seemingly not related to the spectral properties of the PAHs. The [CII] emission from the Orion Nebula complex stems mainly from moderately illuminated PDR surfaces. Future observations with the James Webb Space Telescope can shine light on the PAH properties that may be linked to these variations.

description: This paper investigates the performance of a likelihood ratio test in combination with a polynomial subspace projection approach to detect weak transient signals in broadband array data. Based on previous empirical evidence that a likelihood ratio test is advantageously applied in a lower-dimensional subspace, we present analysis that highlights how the polynomial subspace projection whitens a crucial part of the signals, enabling a detector to operate with a shortened temporal window. This reduction in temporal correlation, together with a spatial compaction of the data, also leads to both computational and numerical advantages over a likelihood ratio test that is directly applied to the array data. The results of our analysis are illustrated by examples and simulations.

description: The D0 collaboration reports direct evidence for electroweak production of single top quarks through the t-channel exchange of a virtual W boson. This is the first analysis to isolate an individual single top quark production channel. We select events containing an isolated electron or muon, missing transverse energy, and two, three or four jets from 2.3 fb^-1 of ppbar collisions at the Fermilab Tevatron Collider. One or two of the jets are identified as containing a b hadron. We combine three multivariate techniques optimized for the t-channel process to measure the t- and s-channel cross sections simultaneously. We measure cross sections of 3.14 +0.94 -0.80 pb for the t-channel and 1.05 +-0.81 pb for the s-channel. The measured t-channel result is found to have a significance of 4.8 standard deviations and is consistent with the standard model prediction.

Observations of small scale distributions of chlorophyll : and related physical parameters in British Columbia coastal waters
Creators: name: Wiegand, Ronald Clive
Publisher: name: University of British Columbia
Year: 2010

description: In the spring of 1973 continuous horizontal measurements were made of temperature, salinity, oxygen and chlorophyll a. in British Columbia coastal waters. The sampling procedure involved a towed pumping system and on-board instrumentation. An effort is made to describe the distributions of the measured parameters with particular emphasis on the smaller scales, less than 250 m. To this end, techniques of power spectral analysis were utilized to examine the data. Results show that there is variability in the nature of the distributions and that the relatedness of the parameters is not consistent, but that on average different experiments show similarities. It appears that to a large extent the distribution of chlorophyll a in an estuarine environment is related to physical transport processes.

description: This thesis describes the development and performance of a full-stack autonomous navigation system. It integrates image and depth-based environmental perception, path planning, and walking control of the NAO humanoid robot for navigation in unknown terrains. The perception module detects walkable surfaces from the camera image and time-to-collide with obstacles from the point cloud data. The path to move from the current position to the destination is solved using a search algorithm. The robot moves along the defined path by the walking controller module. This navigation system is tested on the NAO robot in simulation, and performance results are presented.

description: We present a machine learning model to classify Active Galactic Nuclei (AGN) and galaxies (AGN-galaxy classifier) and a model to identify type 1 (optically unabsorbed) and type 2 (optically absorbed) AGN (type 1/2 classifier). We test tree-based algorithms, using training samples built from the X-ray Multi-Mirror Mission -Newton (XMM-Newton) catalogue and the Sloan Digital Sky Survey (SDSS), with labels derived from the SDSS survey. The performance was tested making use of simulations and of cross-validation techniques. With a set of features including spectroscopic redshifts and X-ray parameters connected to source properties (e.g. fluxes and extension), as well as features related to X-ray instrumental conditions, the precision and recall for AGN identification are 94 and 93 per cent, while the type 1/2 classifier has a precision of 74 per cent and a recall of 80 per cent for type 2 AGN. The performance obtained with photometric redshifts is very similar to that achieved with spectroscopic redshifts in both test cases, while there is a decrease in performance when excluding redshifts. Our machine learning model trained on X-ray features can accurately identify AGN in extragalactic surveys. The type 1/2 classifier has a valuable performance for type 2 AGN, but its ability to generalise without redshifts is hampered by the limited census of absorbed AGN at high redshift.

Evaluation of a Method for Preservation of Surface Water Samples for Analysis of Microbial DNA
Creators: name: Hammond, Caroline C
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: As of 2021 nearly 30% of the world’s population has inadequate access to clean water. Many resource-poor communities rely on surface water sources like rivers and lakes for daily use, possibly exposing these populations to waterborne illnesses. The wide variety of waterborne pathogens makes it difficult to measure them directly, so indicator species are used to monitor water quality instead. Molecular analyses of water samples can provide useful information about microbes and sources. However, the preservation and transport of environmental water requires freezing at -40C, which makes it difficult to conduct important molecular analyses of water samples from rural areas of low-and middle-income countries. Whatman FTA cards are compact and easy to transport, able to preserve nucleic acid at ambient temperature. Use of Whatman cards to collect environmental water samples would allow greater access to rural communities and molecular analyses for faster and more precise detection of pathogens. However, Whatman cards were originally designed for use with clinical samples, and have yet to be evaluated for their ability to preserve microbial DNA from environmental water samples. This research is an evaluation of Whatman cards for this purpose through three trials, comparing the performance of Whatman FTA cards versus polycarbonate filters. First, recovery and range finding for detection of microbial DNA was done. Next, preservation of known concentrations of E. faecalis cells for varying lengths of time was evaluated. Finally, preservation of wastewater effluent samples for varying lengths of time on Whatman FTA cards and polycarbonate filters was evaluated. All samples were evaluated via quantitative PCR and statistical analyses conducted using SAS version 9.4. After our data was determined to have a non-normal distribution, median and range were used to best describe these data. Each storage media type (polycarbonate, Whatman card)at each specific sample concentration confirmed that each sample type was stable overtime, with polycarbonate samples showing a slight decrease in concentrations as storage length increased. Using the Kruskal-Wallis nonparametric comparison test for group comparisons showed that Whatman cards had similar stability across sample concentrations and storage lengths to polycarbonate filter samples stored at -80oC. Based on this research, Whatman cards present an alternative method of microbial DNA preservation from surface water samples, with less limitations in sample storage and transport than current methods. Samples can be stored for at least two months at ambient temperatures without experiencing substantial nucleic acid degradation, though compared to polycarbonate filters at room temperature, Whatman cards produce more consistent Ct values at concentrations of 1 x 104 cells/mL and above.

The Role of CREB3L3 in Adipose Biology and Obesity

description: In this thesis, I investigated the role of cyclic-AMP Responsive Element Binding Protein 3-like-3 (CREB3L3) in adipose tissue. CREB3L3 is an ER-bound transcription factor that is an important regulator of lipid metabolism and has previously been described as liver specific. In the first chapter, we discovered that CREB3L3 is not only expressed in adipose tissue, but selectively downregulated in the more “metabolically healthy” subcutaneous fat in both obese mice and humans in response to ER stress, while expression is unchanged in the visceral fat. To investigate how this transcription factor contributes to adipose biology, we create a CREB3L3 fat-specific knockout (fKO) mouse in the second chapter. When challenged with high-fat diet, the fKO mice became 18% heavier than floxed controls and had significant expansion of their epididymal and inguinal adipose depots. Expansion of the visceral epididymal fat caused the tissue to become more inflammatory as evidenced by an increase in the number of crown-like structures and expression of pro-inflammatory cytokines in the fKO tissue. This led to the fKO mice becoming more insulin resistant following high-fat feeding. In the third chapter we investigated the cause of the larger adipose tissues in the fKO mice. Indirect calorimetry experiments showed that a reduction in whole-body energy expenditure caused the enhanced adiposity of the fKO mice following high-fat feeding. In addition to having a shift in brown fat metabolism from fatty acid oxidation to lipid synthesis, fKO subcutaneous adipocytes were more resistant to browning upon treatment with the β3-adrenergic receptor agonist CL316,243. In the last chapter, we created a subcutaneous fat-specific overexpression model to address whether increased CREB3L3 expression in this tissue would prevent the development of obesity. I found that with only a modest increase in expression of CREB3L3 in subcutaneous fat, diet-induced obesity and insulin resistance is prevented. Taken together, our data show that this transcription factor is important for regulating body weight and inflammation during high-fat feeding. Our comprehensive phenotyping of our mouse models leads us to propose that the amount of CREB3L3 expression in adipose tissue is important for energy homeostasis and body weight regulation during obesity.
Mixmaster universe in the z=3 deformed Hořava-Lifshitz gravity

description: The z=3 deformed Horava-Lifshitz gravity with coupling constants ωand εleads to a nonrelativistic "mixmaster" cosmological model. The potential of theory is given by the sum of IR and UV potentials in the ADM Hamiltonian formalism. It turns out that the presence of the UV-potential cannot suppress chaotic behaviors existing in the IR-potential, which comes from curvature anisotropy.

Assessment of Defects in Steel Structures Using UAVs and Image-Based 3D Reconstruction

description: The resolution of visual image and the accuracy of 3D reconstruction of complex structural geometries using a camera carried by drones are important indicators to adapt the methodology as a quantitative bridge inspection tool. This thesis aims to determine and optimize the accuracy of defect and dimensional measurements using 3D reconstruction and image processing tools for multi-girder steel bridges. Additionally, a passive visual sensor is developed that amplified the strain in the base structure, making non-visual plastic deformations able to be captured visually. A safe data collection route is defined considering the constraints of diaphragms and spacing between girders with the objective of creating a high-resolution 3D reconstruction of complex girder geometry. Qualitative accuracy was explored in the 3D model to determine the camera angles, elevations and working distance. The lowest percent error achieved in this study for 3D quantitative results using ad hoc measurement on overall accuracy in the girder geometry was 5.92% using 332 images. Using the proposed systematic methodology as a guideline in a more realistic setup, a percent error of 32.82% was achieved using 43 images, which significantly reduces the flight time without sacrificing from accuracy.

description: We report low mass companions orbiting five Solar-type stars that have emerged from the Magellan precision Doppler velocity survey, with minimum (Msini) masses ranging from 1.2 to 25 Mjup. These nearby target stars range from mildly metal-poor to metal-rich, and appear to have low chromospheric activity. The companions to the brightest two of these stars have previously been reported from the CORALIE survey. Four of these companions (HD 48265-b, HD 143361-b, HD 28185-b, HD 111232-b) are low-mass Jupiter-like planets in eccentric intermediate and long-period orbits. On the other hand, the companion to HD 43848 appears to be a long period brown dwarf in a very eccentric orbit.

description: Wildfires typically affect multiple forest ecosystem services, with carbon sequestration being affected both directly, through the combustion of vegetation, litter and soil organic matter, and indirectly, through perturbation of the energy and matter balances. Post-fire carbon fluxes continue to be poorly studied at the ecosystem scale, especially during the initial window of disturbance when changes in environmental conditions can be very pronounced due to the deposition and subsequent mobilization of a wildfire ash layer and the recovery of the vegetation. Therefore, an eddy-covariance system was installed in a burnt area as soon as possible after a wildfire that had occurred on 13 August 2017 and has been operating from the 43rd post-fire day onwards. The study site was specifically selected in a Mediterranean woodland area dominated by maritime pine stands with a low stature that had burned at high severity. The carbon fluxes recorded during the first post-fire hydrological year tended to be very low so that a specific procedure for the analysis and, in particular, gap filling of the eddy-covariance data had to be developed. Still, the carbon fluxes varied noticeably during the first post-fire year, broadly revealing five consecutive periods. During the rainless period after the wildfire, fluxes were reduced but, somewhat surprisingly, indicated a net assimilation. With the onset of the autumn rainfall, fluxes increased and corresponded to a net emission, while they became insignificant with the start of the winter. From the midwinter onwards, net fluxes became negative, indicating a weak carbon update during spring followed by a strong uptake during summer. Over the first post-fire year as a whole, the cumulative net ecosystem exchange was −347 g C m−2, revealing a relatively fast recovery of the carbon sink function of the ecosystem. This recovery was mainly due to understory species, both resprouter and seeder species, since pine recruitment was reduced. Specific periods during the first post-fire year were analyzed in detail to improve process understanding. Perhaps most surprisingly, dew formation and, more specifically, its subsequent evaporation were found to play a role in carbon emissions during the rainless period immediately after fire, involving a mechanism distinct from degassing the ash–soil pores by infiltrating water. The use of a special wavelet technique was fundamental for this inference.

description: We describe an algorithm that takes as input a complex sequence $(u_n)$ given by a linear recurrence relation with polynomial coefficients along with initial values, and outputs a simple explicit upper bound $(v_n)$ such that $|u_n| \leq v_n$ for all $n$. Generically, the bound is tight, in the sense that its asymptotic behaviour matches that of $u_n$. We discuss applications to the evaluation of power series with guaranteed precision.

description: We present the first measurements at a hadron collider of differential cross sections for Z+jet+X production in delta phi(Z, jet), |delta y(Z, jet)| and |y_boost(Z, jet)|. Vector boson production in association with jets is an excellent probe of QCD and constitutes the main background to many small cross section processes, such as associated Higgs production. These measurements are crucial tests of the predictions of perturbative QCD and current event generators, which have varied success in describing the data. Using these measurements as inputs in tuning event generators will increase the experimental sensitivity to rare signals.
