description: We have successfully applied full-3-D tomography (F3DT) based on a combination of the scattering-integral method (SI-F3DT) and the adjoint-wavefield method (AW-F3DT) to iteratively improve a 3-D starting model, the Southern California Earthquake Center (SCEC) Community Velocity Model version 4.0 (CVM-S4). In F3DT, the sensitivity (Fréchet) kernels are computed using numerical solutions of the 3-D elastodynamic equation and the nonlinearity of the structural inversion problem is accounted for through an iterative tomographic navigation process. More than half-a-million misfit measurements made on about 38,000 earthquake seismograms and 12,000 ambient-noise correlagrams have been assimilated into our inversion. After 26 F3DT iterations, synthetic seismograms computed using our latest model, CVM-S4.26, show substantially better fit to observed seismograms at frequencies below 0.2 Hz than those computed using our 3-D starting model CVM-S4 and the other SCEC CVM, CVM-H11.9, which was improved through 16 iterations of AW-F3DT. CVM-S4.26 has revealed strong crustal heterogeneities throughout Southern California, some of which are completely missing in CVM-S4 and CVM-H11.9 but exist in models obtained from previous crustal-scale 2-D active-source refraction tomography models. At shallow depths, our model shows strong correlation with sedimentary basins and reveals velocity contrasts across major mapped strike-slip and dip-slip faults. At middle to lower crustal depths, structural features in our model may provide new insights into regional tectonics. When combined with physics-based seismic hazard analysis tools, we expect our model to provide more accurate estimates of seismic hazards in Southern California.

description: No abstracts are to be cited without prior reference to the author.The composition of fatty acids in selected tissues of three redfish species, two populations of cod and two populations of herring was determined by a chemometric method, consisting of methanolysis, gas chromatography of the resulting fatty acid methyl esters and multivariate, statistical treatment of the analytical data. The two reared stocks of cod from the Faroe Bank and the Faroe Plateau had significantly different fatty acid profiles in total lipids and in phospolipids from heart tissue. This difference is expected to be genetic and free of biotic and abiotic impacts on the fatty acid profiles. The three species of redfish from waters off the Faroe Islands and Norway had significantly different fatty acid profiles in selected tissues. The fatty acid profiles appear to be species specific. The mutual relationship between Sebastes marinus and S. mentella is closer than the relationship between either of them and S. viviparus. The fatty acid profile in the heart tissue of S. mentella from eleven locations in the waters off Norway, Faroe Islands, Iceland and from two strata at different depths in the Irminger Sea indicate the presence of four separate stocks of this redfish species in the North East Atlantic Ocean. Herring from the North Sea stock and the stock of Norwegian Spring Spawners were distinguished by way of the fatty acid profile in the filet. A new method for stock identification on the individual level is established.

description: No abstracts are to be cited without prior reference to the author.The population dynamics of a fish stock can be investigated through knowledge of the stock-recruitment relationship and the replacement line associated with biological characteristics such as age growth, maturity and natural mortality. While functions defining the replacement line are generally easily formulated, it is more problematic to specify the stock-recruitment relationship. Using a non-parametric model for the stock-recruitment relationship it is possible to avoid defining specific functions relating recruitment to stock size while also providing a natural framework to model process error. This paper describes a kernel method approach to modelling the recruitment data, that takes into account uncertainty, which leads to an empirical method for investigating the population dynamics of exploited populations under a range of fishing scenarios.

description: No abstracts are to be cited without prior reference to the author.A male and female harbour porpoise, taken into human care at the Fjord and Belt Centre in April 1997, are housed in an outdoor pool area off Kerteminde fjord, Denmark. The estimated age was 2-3yr for both animals so that current ages are 6-7yr (April 2001). Growth has been monitored since capture by means of body length and weight, girth, blubber thickness, and dietary intake. Each food batch has been analysed biochemically. Their weights have fluctuated seasonally during the period, with increasing weight from October, peak in January, and rapid loss in spring around April. Girth and blubber thickness mirror these weight fluctuations. Food intake has also fluctuated seasonally, but increases have preceded weight gains. Daily food consumption ranged from 3.5 – 4.5 kg (ca 7 – 9.5% body weight). During the 48 months since capture, lengths have increased steadily from 130.5 – 141 cm (male), and from 127.5 – 151 cm (female), and initial weights from 37.5 – max.47 kg (male) and 40.5–max.60 kg (female). Body lengths and weights compare favourably with expected body sizes determined from by-caught porpoises in the region. We anticipate that seasonal changes in body fat are correlated both with water temperature and summer reproductive activity, suggesting that blubber fat may serve as insulation and energy reserves.

description: Al$_x$Sc$_{1-x}$ thin films have been studied with compositions around Al$_3$Sc ($x$ = 0.75) for potential interconnect metallization applications. As-deposited 25 nm thick films were x-ray amorphous but crystallized at 190°C, followed by recrystallization at 440°C. After annealing at 500°C, 24 nm thick stoichiometric Al$_3$Sc showed a resistivity of 12.6 $μΩ$cm, limited by a combination of grain boundary and point defect (disorder) scattering. Together with ab initio calculations that found a mean free path of the charge carriers of 7 nm for stoichiometric Al$_3$Sc, these results indicate that Al$_3$Sc bears promise for future interconnect metallization schemes. Challenges remain in minimizing the formation of secondary phases as well as in the control of the non-stoichiometric surface oxidation and interfacial reactions with underlying dielectrics.

description: The application of stable isotope analysis to ecology requires estimating the contribution of different isotopic sources to the isotopic signatures of an animal's tissues using mixing models. These models make the physiologically unrealistic assumption that assimilated nutrients are disassembled into their elemental components and that these atoms are then reassembled into biomolecules. We quantified the extent to which mixing models yield erroneous results with an experiment using Nile tilapia (Oreochromis niloticus). The tilapia were fed synthetic diets that varied in protein content and in which the carbon isotopic composition of protein differed widely from that of carbohydrates and lipids. We predicted that dietary protein would contribute disproportionately to the carbon in muscle, whereas the nonprotein components of diet would contribute disproportionately to lipids. Our experiment also allowed us to test the conjecture of a positive correlation between the 15N enrichment in tissues and protein intake. As predicted, the contribution of protein carbon to muscle was higher than that expected by the assumptions of isotopic mixing in all treatments except that with the lowest dietary protein content. We hypothesized that the unexpectedly high contribution of nonprotein carbon to muscle was the result of assimilating both dispensable and indispensable amino acids synthesized by the fishes' gut microbiota. Although we expected the contribution of carbon in nonprotein dietary ingredients to be higher than expected from a mixing model, we found that protein contributed more than expected, probably as a result of differences in amino acid composition between diet and tissues, which led to excess carbon used for lipid synthesis. Finally, our results verified the positive relationship between dietary protein content and the enrichment in tissue 15N. Assuming perfect mixing in field isotopic studies can lead to erroneous inferences about the relative contributions of different sources to an animal's diet.

description: No abstracts are to be cited without prior reference to the author.The primary objective of this work is to compare patterns of allozyme and RAPD variation in six Atlantic populations of Solea solea. Sixteen individuals were randomly selected from each of the six Atlantic populations of S. solea sampled during 1994 and 1995. In total, 96 individuals were screened from three Irish Sea, two North Sea and one Bay of Biscay populations. Allozyme and RAPD markers produced results, which were in general agreement with each other. However, RAPD markers detected more variation in the sampled sole populations than that observed by using allozyme marker. Percentage of polymorphism and genetic diversity estimates were very high. There was clearly no geographic trend to any RAPD or allozyme allele frequencies at all polymorphic loci. The chi-square contingency analyses (allele frequencies and hierarchical FST and non- hierarchical FDT) indicated a highly significant heterogeneity among populations and between groupings. This conclusion is consistent with the life history of Dover sole, the homing behaviour they exhibit and the discrete spawning areas. A north to south pattern of significant population differentiation in the allozyme study was replaced by a northwest to southeast significant variation. Natural selection for differences in spawning habitat may explain the genetic isolation between these groupings. Another reason could be the significant absence of some alleles, present in the southern European populations. Evidence in favour of the divergence between these regions is shown by the cluster analyses (UPGMA, Wagner procedure) of both allozyme and RAPD data. However, allozymes provided a slightly better fit of data to predictions about genetic distance (higher values of cophenetic correlation of clusters from the Goodness of fit statistics) and better correlation between genetic and geographic distances (Mantel’s r). In both studies a strong similarity between the Bay of Biscay and the German Bight populations was evident, judging from their clustering positions. It was apparent that the trend of probable movement of migrants through the English Channel suggested by the allozyme study was supported using RAPD markers. The apparent absence of isolation-by-distance (non significant correlation of genetic with geographic distance) in both studies suggests that S. solea may not yet be at genetic equilibrium. Overall, S. solea conforms to the type of species with either a broad variety of geographic and ecological habitats, or large and stable population sizes, or substantial gene flow at a regional scale.

description: No abstracts are to be cited without prior reference to the author.The Vistula Lagoon is an interesting research area. It is a shallow, semi-enclosed lagoon, divided by the Russian-Polish border, with an average depth of 2.7 meters. Since the only connection with the Baltic Sea is the strait in the vicinity of Baltijsk in Russia, the salinity in the Polish part is low and ranges from 3.6 PSU close to the Russian-Polish border to 0.7-1.3 PSU in the southwestern part. It is also an extremely eutrophic area and Secchi depth usually does not exceed 1.0 m. Because of its shallowness, stronger winds can significantly influence turbidity. Rapid changes in water temperature that are caused by solar radiation are also observed.

description: The Reynolds-averaged Navier-Stokes (RANS) equations provide a computationally efficient method for solving fluid flow problems in engineering applications. However, the use of closure models to represent turbulence effects can reduce their accuracy. To address this issue, recent research has explored data-driven techniques such as data assimilation and machine learning.
 An efficient variational data assimilation (DA) approach is presented to enhance steady-state eddy viscosity based RANS simulations. To account for model deficiencies, a corrective force term is introduced in the momentum equation. In the case of only velocity reference data, this term can be represented by a potential field and is divergence-free. The DA implementation relies on the discrete adjoint method and approximations for efficient gradient evaluation.
 The implementation is based on a two-dimensional coupled RANS solver in OpenFOAM, which is extended to allow the computation of the adjoint velocity and pressure as well as the adjoint gradient. A gradient-based optimizer is used to minimize the difference between the simulation results and the reference data. To evaluate this approach, it is compared with alternative data assimilation methods for canonical stationary two-dimensional turbulent flow problems. For the data assimilation, sparsely distributed reference data from averaged high-fidelity simulation results are used.
 The results suggest that the proposed method achieves the optimization goal more efficiently compared to applying data assimilation for obtaining the eddy viscosity, or a field modifying the eddy viscosity, directly. The method works well for different reference data configurations and runs efficiently by leveraging coarse meshes.

description: The predominance of technocrats within the Reichswehr, the inability of the officer corps to reassert its elite status in the Weimar era, and the extensive interaction between the Reichswehr and a militaristic German society contributed to Hitler's successful absorption of military authority in the 1930s. The social and political upheaval resulting in part from the First World War diffused military authority and diminished the role of the officer corps in German society. The corps struggled to maintain its historic level of corporateness and consistently failed to fulfill its responsibility to the Weimar Republic. The Reichswehr's top officers worked to revitalize the armed forces with one eye on the past and the other on the future, but always they were aware of the intolerable present constructed by the Treaty of Versailles.

Interwar officer selection, training, and codes of conduct were designed to resurrect the values of the Imperial Army while also preparing for the new technological battlefield. The incompatibility of these two missions made it difficult for the officer corps to establish an institutional identity. Internal debates raged in the Reichswehr, but additional pressures came from a polarized Weimar society. Contrary to the traditional interpretation that the Reichswehr was a state within a state, evidence presented here suggests that the officer corps was not immune to the Weimar Republic's cultural excesses. Under these circumstances the acceptance of the oath of allegiance to Hitler on the part of the officer corps was fateful, but certainly not surprising. The 1934 oath was dangerous because it resurrected the worst elements of the Prussian past and combined them with the destructive impulses of the Third Reich. By deconstructing the existing secondary literature and including other methodologies, such as film and literary criticism, a more complex picture of the officer corps emerges. Primary sources include military attache reports and German military journals.

description: A paired catchment methodology was used with more than 3 years of data to test whether forests increase base flow in the dry season, despite reduced annual runoff caused by evapotranspiration (the sponge-effect hypothesis), and whether forests reduce maximum runoff rates and totals during storms. The three study catchments were: a 142.3 ha old secondary forest, a 175.6 ha mosaic of mixed age forest, pasture, and subsistence agriculture, and a 35.9 ha actively grazed pasture subcatchment of the mosaic catchment. The two larger catchments are adjacent, with similar morphology, soils, underlying geology, and rainfall. Annual water balances, peak runoff rates, runoff efficiencies, and dry season recessions show significant differences. Dry season runoff from the forested catchment receded more slowly than from the mosaic and pasture catchments. The runoff rate from the forest catchment was 1-50% greater than that from the similarly sized mosaic catchment at the end of the dry season. This observation supports the sponge-effect hypothesis. The pasture and mosaic catchment median runoff efficiencies were 2.7 and 1.8 times that of the forest catchment, respectively, and increased with total storm rainfall. Peak runoff rates from the pasture and mosaic catchments were 1.7 and 1.4 times those of the forest catchment, respectively. The forest catchment produced 35% less total runoff and smaller peak runoff rates during the flood of record in the Panama Canal Watershed. Flood peak reduction and increased streamflows through dry periods are important benefits relevant to watershed management, payment for ecosystem services, water-quality management, reservoir sedimentation, and fresh water security in the Panama Canal watershed and similar tropical landscapes.

description: With the advent of massive data sets much of the computational science and engineering community has moved toward data-intensive approaches in regression and classification. However, these present significant challenges due to increasing size, complexity and dimensionality of the problems. In particular, covariance matrices in many cases are numerically unstable and linear algebra shows that often such matrices cannot be inverted accurately on a finite precision computer. A common ad hoc approach to stabilizing a matrix is application of a so-called nugget. However, this can change the model and introduce error to the original solution. It is well known from numerical analysis that ill-conditioned matrices cannot be accurately inverted. In this paper we develop a multilevel computational method that scales well with the number of observations and dimensions. A multilevel basis is constructed adapted to a kD-tree partitioning of the observations. Numerically unstable covariance matrices with large condition numbers can be transformed into well conditioned multilevel ones without compromising accuracy. Moreover, it is shown that the multilevel prediction exactly solves the Best Linear Unbiased Predictor (BLUP) and Generalized Least Squares (GLS) model, but is numerically stable. The multilevel method is tested on numerically unstable problems of up to 25 dimensions. Numerical results show speedups of up to 42,050 times for solving the BLUP problem, but with the same accuracy as the traditional iterative approach. For very ill-conditioned cases the speedup is infinite. In addition, decay estimates of the multilevel covariance matrices are derived based on high dimensional interpolation techniques from the field of numerical analysis. This work lies at the intersection of statistics, uncertainty quantification, high performance computing and computational applied mathematics.

description: Understanding personality is often a crucial component in conceptualizing psychopathology and treatment methodology for those seeking psychotherapy services. Despite this, personality assessment is underutilized in clinical practice, and available therapeutic applications of personality assessment do not incorporate advances in personality science . The Person in Context Assessment (PICA) provides a clinical application of the social cognitive theory of personality, which assesses a variety of underlying personality structures and personality processes that interact and create patterns of thoughts, behaviors, and emotions within environmental contexts. This study examined PICA as a supplementary therapeutic tool alongside ongoing therapy services in a single clinical case study of a participant with chronic moderate depression who was not responding to intervention efforts. After completing the PICA procedure and receiving personality feedback, the participant reported a significant decrease in depression symptoms, which dropped from the moderate into the minimal/mild severity range. Minor increases were also found in the participant’s motivation to change in therapy, generalized self-efficacy, and perception of therapy credibility. Examination of the participant’s therapy sessions notes suggested improved case conceptualization and the application of therapy treatment recommendations from the PICA procedure feedback as major contributors to depression symptom improvement. However, any direct therapeutic effect of the PICA procedure appeared limited. The results of this study provided further evidence for the validity of PICA and its potential therapeutic utility. Future investigation of PICA and its underlying therapeutic mechanisms within larger clinical case samples, as compared against other personality assessment measures, is warranted.

description: This paper presents a method for the fast and accurate estimation of the gain pattern and maximum gain of an implanted antenna including the effect of the host body, under the assumption that the latter is electrically large. The estimation procedure is based on the radiation of an elementary dipole source placed in a planar body model. The derivation of closed-form expressions is based on spherical wave analysis and the Green's functions for layered media. The validity of this approximation for practical cases is shown on different implanted antennas, where the results are compared to full wave simulations and measurements.

description: We analyze the amplitude fluctuations in a diluted 3D classical XY model near the magnetic phase transition, motivated by the unusual localization properties of the amplitude (Higgs) mode recently found at the disordered superfluid-Mott glass quantum phase transition. We calculate the amplitude correlation function and the corresponding scalar susceptibility by means of Monte Carlo simulations. In contrast to the quantum case, in which the scalar susceptibility was found to violate naive scaling, we find that the scalar susceptibility of the classical system fulfills naive scaling (employing the clean critical exponents, as expected from the Harris criterion) as the temperature is varied across the phase transition for several dilutions. We discuss possible reasons for this discrepancy as well as the generality of our findings.

description: No abstracts are to be cited without prior reference to the author.Extensive stomach sampling programmes of North Sea fish during the recent 2 decades have shown that cod (Gadus morhua), whiting (Merlangius merlangus) and saithe (Pollachius virens) are by far the main predators on Norway pout (Trisopterus esmarkii) of age 1 and older. As the stock sizes of cod, whiting and saithe have decreased significantly over the period this offers a unique opportunity to test whether a decrease in natural mortality of Norway pout can be detected in mortality estimates obtained directly from abundance data of Norway pout. Two surveys, which cover the Norway pout distribution well, have been analyzed in this regard. Both showed clear decrease in total mortality consistent with the decrease in amounts of predators. The level of predation mortality is similar to that from the ICES North Sea Multispecies model (MSVPA), but the MSVPA does not reflect the variation in mortality over time. It is speculated that this might be a consequence of the model ignoring a very high mortality of Norway pout of age 2 and older possibly due to spawning or growth stress.

description: No abstracts are to be cited without prior reference to the author.The duration, frequency and peak of sprat spawning in the 1999 spawning season are described. Spatial and year to year variations in the timing of spawning were analysed utilising maturity data obtained in June 1999 in ICES Sub-divisions 25, 26 and 27 / 28, respectively in April 1995, 1996, 1998 and 1999 in Sub-division 25. All analysis were based on gonadal maturity inspections of catches obtained from hydro acoustic- and trawl surveys as well as commercial fisheries. The sprat spawning season in 1999 lasted from February to July peaking in June with an average spawning frequency of 27% during main spawning time. The course of the 1999 season was validated against egg abundance data obtained from ichthyoplankton surveys conducted in parallel. Marked differences in the timing of spawning were found between the Bornholm Basin / Gdansk Deep and the Gotland Basin with delayed spawning activities of sprat in the latter. Both areas encounter pronounced differences in the temperature regime, whereas the Gotland Basin is characterised by the colder water temperatures. Furthermore, a consistent trend towards later spawning in most recent years has been observed. This trend was negatively related to the recently declining total biomass concurrent with increasing landings, but not to winter water temperatures.

description: We generalize some properties of surface automorphisms of pseudo-Anosov type. First, we generalize the Penner construction of a pseudo-Anosov homeomorphism and show that a symplectic automorphism which is constructed by our generalized Penner construction has an invariant Lagrangian branched submanifold and an invariant Lagrangian lamination, which are higher-dimensional generalizations of a train track and a geodesic lamination in the surface case. Moreover, if a pair consisting of a symplectic automorphism $ψ$ and a Lagrangian branched surface $B_ψ$ satisfies some assumptions, we prove that there is an invariant Lagrangian lamination $\mathcal{L}$ which is a higher-dimensional generalization of a geodesic lamination.

description: Silvopasture in Washington State is not well studied and thus little is known about this practice in this region. The first objective of this research project was to understand farm composition and farmer goals for silvopasture. To accomplish this, I conducted a statewide survey administered via interviews of practitioners to determine the social, economic, and ecological drivers and demographics of farmers utilizing silvopasture. To identify landowners using silvopasture and gain insights into its perceived usage and impacts, I contacted and interviewed multiple state and federal agency representatives. This research provided evidence that silvopasture is being used and that further research is needed to determine the economic viability and ecological effects of this practice.A second objective was to determine the effects of silvopasture and other types of forest grazing on forest structure, composition, and edaphic properties. Due to the combined effects of fire suppression and historic logging and grazing practices; dry pine forests of the Interior Columbia Basin are susceptible to high severity fires, soil compaction, and erosion. Limited research suggests that silvopasture may reduce fuel loads while maintaining ecosystem services. Through field data collection and statistical analyses, I determined that the prescribed grazing density associated with silvopasture and continuous grazing reduced litter, duff, and surface vegetation without significant alteration of vascular plant evenness and abundance. Analysis of physical and chemical soil properties determined that silvopasture resulted in significantly lower bulk density and soil compaction than continuous grazing but both measures were higher than in ungrazed sites. Similarly electrical conductivity was highest in continuously grazed sites when compared to silvopasture sites. This suggests that silvopasture is a more suitable land management practice when compared to more traditional forest grazing methods.

description: Quantum Monte Carlo (QMC) can play a very important role in generating accurate data needed for constructing potential energy surfaces. We argue that QMC has advantages in terms of a smaller systematic bias and an ability to cover phase space more completely. The stochastic noise can ease the training of the machine learning model. We discuss how stochastic errors affect the generation of effective models by analyzing the errors within a linear least squares procedure, finding that there is an advantage to having many relatively imprecise data points for constructing models. We then analyze the effect of noise on a model of many-body silicon finding that noise in some situations improves the resulting model. We then study the effect of QMC noise on two machine learning models of dense hydrogen used in a recent study of its phase diagram. The noise enable us to estimate the errors in the model. We conclude with a discussion of future research problems.

description: Two-dimensional semiconductor-superconductor heterostructures form the foundation of numerous nanoscale physical systems. However, measuring the properties of such heterostructures, and characterizing the semiconductor in-situ is challenging. A recent experimental study [arXiv:2107.03695] was able to probe the semiconductor within the heterostructure using microwave measurements of the superfluid density. This work revealed a rapid depletion of superfluid density in semiconductor, caused by the in-plane magnetic field which in presence of spin-orbit coupling creates so-called Bogoliubov Fermi surfaces. The experimental work used a simplified theoretical model that neglected the presence of non-magnetic disorder in the semiconductor, hence describing the data only qualitatively. Motivated by experiments, we introduce a theoretical model describing a disordered semiconductor with strong spin-orbit coupling that is proximitized by a superconductor. Our model provides specific predictions for the density of states and superfluid density. Presence of disorder leads to the emergence of a gapless superconducting phase, that may be viewed as a manifestation of Bogoliubov Fermi surface. When applied to real experimental data, our model showcases excellent quantitative agreement, enabling the extraction of material parameters such as mean free path and mobility, and estimating $g$-tensor after taking into account the orbital contribution of magnetic field. Our model can be used to probe in-situ parameters of other superconductor-semiconductor heterostructures and can be further extended to give access to transport properties.

Kaluza-Klein tower and bubble nucleation in six dimensional Einstein-Maxwell theory

description: We study the implication of the distance and the cobordism conjecture on the 6-dimensional Einstein-Maxwell theory compactified on $S^2$. In this toy model, the radion potential is stabilized by the conspiracy of the curvature of $S^2$ and the flux through $S^2$ parametrized by $f$, and uplifted by the positive 6-dimensional cosmological constant parametrized by $λ$. When $λ=0$, the radion is stabilized at the anti-de Sitter (AdS) vacuum, which cannot be interpolated to the Minkowski vacuum since the Kaluza-Klein (KK) tower descends from UV in the vanishing limit of the 4-dimensional cosmological constant. For nonzero $λ$ which realizes the metastable de Sitter (dS) vacuum, as well as the AdS and the Minkowski vacuum, such an obstruction can be found provided the combination $f^2λ$ is fixed and the limit $λ\to 0$ is taken. Moreover, the 6-dimensional Einstein-Maxwell theory allows the transition between vacua through the nucleation of the bubble. In this case, the values of the 4-dimensional cosmological constant inside and outside the bubble are different as $f$ is changed at the bubble wall, while $λ$ remains unchanged. Regarding the AdS vacuum with the vanishing curvature radius as the `nothing', we find that the transition from the metastable dS vacuum to the nothing is not prevented by the descent of the KK tower since $f^2λ$ is not fixed.
