description: A new equation of state for argon has been developed in view to extend the range of validity of the equation of state previously proposed by Tegeler et al. (Ref. 4) and to obtain a better physical description of the experimental thermodynamic data for the whole fluid region (single-phase, metastable and saturation states). As proposed by Tegeler et al., this equation is also based on a functional form of the residual part of the reduced Helmholtz free energy. However in this work, the fundamental equation for the Helmholtz free energy has been derived from the measured quantities CV(rho,T) and P(rho,T). The empirical description of the isochoric heat capacity CV(rho,T) is based on an original empirical description containing explicitly the metastable states. The thermodynamic properties (internal energy, entropy, free energy) are then obtained by combining integration of CV(rho,T). The arbitrary functions introduced by the integration process have been deduced from a comparison between calculated and experimental pressure P(rho,T) data. The new formulation is valid for the whole fluid region from the melting line to 2300 K and for pressures up to 50 GPa. It also predicts existence of a maximum of the isochoric heat capacity CV along isochors as experimentally observed in several other fluids. For many applications, an approximate form of the equation of state for the liquid phase may be sufficient. A Tait-Tammann equation is therefore proposed between the triple point temperature and 148 K.

description: We have presented a pathway to map the internal structure of lowest-lying octet baryons by using one-loop quantum fluctuations of a fermion state in Yukawa theory. The structural interpretation of baryons carrying different amount of strange content has been exemplified by employing a quark-scalar diquark model for studying the Generalized Parton Distributions (GPDs) among the members of octet baryons. Different possible combinations of quark-scalar diquark pairs have been considered. The quark helicity independent chiral even GPDs in momentum as well as impact parameter space have been studied for purely transverse momentum transfer (zero skewness). We have also extended our calculations to explore and visualize the distinct behavior of charge distributions in coordinate space as well as charge densities in impact parameter space. Furthermore, magnetization density in impact parameter space has also been investigated. Quantitative as well as qualitative analysis of all the distributions has been carried out.

description: No abstracts are to be cited without prior reference to the author.The impact of bivalve fisheries on the benthic ecosystem was assessed in areas under different impact stress: the Ria Formosa lagoon (Portugal), the Venice lagoon (Italy), and the north Aegean Sea (Greece). Ecosystem changes attributable to fishing impacts were assessed in the short term (hours to days) with the RNA/DNA condition index and sediment recover, medium term (days to weeks) with ecophysiological indices (filtration rates, excretion rates, respiration rates and scope for gowth), and in the long term (months to years) by changes in diversity and sediment characteristics. Lower RNA/DNA ratios occurred in the fished areas of Ria Formosa, suggesting a decrease in the ecophysiological condition of the target species caused by cumulative fishing impact, but this was not evident in the Venice lagoon. However, for the physiological indices, similar trends of metabolism decrease in fished areas were observed in both Venice lagoon and the Ria Formosa. In these areas, a decrease in macrofauna diversity was observed, while in the Aegean sea this was not evident. Analysis of the impacts in the studied areas showed that, in the short and medium term, mechanical gears (Italian hydraulic dredges) may cause more impact on the benthic ecosystem than do manual fishing (Portuguese clam hacks) or Greek towed dredges. However, in the long term, procedures involved in Portuguese fishing (cleaning of macroalgae from intertidal areas, artificial changes to sediment grain size, and juvenile seeding) may cause more significant changes to the ecosystem.

description: The high Fe-Ti eclogites with exsolved lamellar in 530-600 m depths from the Chinese Continental Scientific Drilling (CCSD) main hole in the Sulu Ultra-High Pressure (UHP) metamorphic belt, eastern China, record an anomalously high susceptibility (κ), natural remanent magnetization (NRM) and Köenigsberger ratio Q (NRM/Ji, Ji is induced magnetization). This provides us with a good opportunity to study the effects of magnetic minerals and exsolution lamellae on the magnetic properties of deep rocks. In this paper, we have measured systematically magnetic properties and mineral assemblage and structure for three special samples (No. 83, No. 86 and No. 89). Results show that these Fe-Ti-rich eclogites are the result of the fine-grained (titano)-magnetite exsolution in pyroxene and lamellar structure consisting of finely interlayered ilmenite and hematite in exsolved hemo-ilmenite. We found that the dominant Fe-bearing oxide minerals in samples studied are ilmenite, hematite (Hem + Ilm up to 25%), little (titano)magnetite and pyrite. The ferromagnetic susceptibility is mainly controlled by fine grained (titano)magnetite and NRM is closely related to the exsolved lamellar structure. We hence propose that the anomalous magnetism of these eclogites observed in our samples is the result of exsolution from homogenous pyroxene and ilmeno-hematite during cooling and decompression processes. These Fe-Ti-rich eclogites might be one of the sources of high-magnetic anomalies observed in the Sulu subduction zone, eastern China.

description: No abstracts are to be cited without prior reference to the author. Coastal ecosystems are under significant threats from pollution, overexploitation, and habitat loss. The world community has come to agreement on international instruments identifying environmental and resource problems, but has been unable to muster the scientific community and the political will to enact necessary policy reforms and devote necessary funding to reverse this trend. An ecosystems approach is emerging for the assessment and management of coastal waters utilizing modular strategies for linking science-based assessments of the changing states of Large Marine Ecosystems (LMEs) to socioeconomic benefits expected from achieving long-term sustainability of their resources. These modules - (1) productivity/environmental variability; (2) fish and fisheries; (3) pollution/ecosystem health; (4) socioeconomics; and (5) governance - serve as a framework for projects in developing countries. To assist in the implementation of this approach, the Global Environment Facility and its $2 billion trust fund has been opened, building on partnerships with the United Nations Development Programme, the UN Environmental Programme, and the World Bank. The LME projects presently funded or being developed represent a broad global spectrum of stakeholders, including public and private sector interests of 14 countries in Asia, 20 countries in Africa, 16 countries in Central and South America, and 9 countries in Europe.

description: No abstracts are to be cited without prior reference to the author.It has been generally stated that fish exploited by deepwater fisheries cannot sustain high levels of fishing pressure because of their characteristic slow growth, longevity and low reproductive output. Irish surveys (1993-2000) allowed for studies of age, growth, fecundity and maturity of several deepwater teleosts and elasmobranchs. These data show that Coryphaenoides rupestris is slow growing and has low fecundity. Other teleosts displayed rather conservative life-history characteristics. The shark Deania calceus was slower growing than the teleosts and Centrophorus squamosus attained ages of up to 71 years. The implications of the life-history parameters for sustainable exploitation are discussed by way of comparison with continental shelf species from this region. These data allowed for the estimation of the rate of potential population increase that supports the view that deepwater species are more vulnerable to exploitation. Whilst there may be scope for compensatory changes in fecundity such scope is likely to be limited, especially for sharks. Fisheries management plans should consider these differing life-history traits. The very different life history strategies exhibited by shelf and deepwater species suggests that different management systems will be required for deepwater fisheries to those prosecuted on the shelf.

description: The Intermontane terranes represent one of the largest composite accreted terranes that built the northern Cordillera. To better understand the interactions between the continental margin of Laurentia and the Intermontane terranes, this study analyzes twelve detrital zircon samples (n=3232) from a Neoproterozoic (?) to Cretaceous metasedimentary stratigraphic section exposed in central Alaska. Distinct detrital zircon populations have been identified and are interpreted to represent four stages in the geologic development of this part of western North America. Stage 1 extends from the Neoproterozoic (?) to the Early Paleozoic, and is characterized by Proterozoic and Archean detrital zircon populations that correlate with Laurentian sources of sediment. We interpret Stage 1 to represent deposition along the northwestern continental margin of Laurentia. Stage 2 extends from the Silurian (?) to the Devonian and is characterized by a dominant Devonian and Silurian detrital zircon population. We interpret Stage 2 to have been deposited in a backarc basin coeval with active volcanism as the Yukon-Tanana terrane was rifted away from the Laurentian continental margin as the Slide Mountain Ocean opened. Stage 3 extends from the Mississippian to the Jurassic and records a shift back to sediment sources with abundant Proterozoic and Archean zircon. We interpret this stage to represent deposition of Laurentian detritus along the eastern margin of the Slide Mountain Ocean basin. Stage 4 is represented by the Lower Cretaceous strata of the Manley basin that contain one major Late Triassic to Early Jurassic detrital zircon population. We interpret this population to be sourced from the syn-collisional and post-collisional Late Triassic to Early Jurassic plutons and related sedimentary basins of the Intermontane terranes that were exhumed and eroded during the closure of the Slide Mountain Ocean and the subsequent collision with the Laurentian continental margin. We interpret the Manley basin as a syn- to post-collisional extensional basin associated with regional detachment faults that formed because of crustal thickening in the collisional zone. From a regional perspective, an extensive clastic wedge prograded northward away from the zone of crustal thickening and can be identified in a series of Mesozoic sedimentary basins that are discontinuously exposed over 1500 km in southern Alaska. Results of our study better delineate the tectonic processes that set the framework for the construction of the Late Mesozoic and Cenozoic Cordilleran orogen.

description: Premise of the study: Population genetic analyses provide information on the population context in which evolutionary processes operate and are important for understanding the evolution of geographically variable traits. Earlier studies showed that cone structure of lodgepole pine in the Rocky Mountains diverged among populations because of geographic variation in co-evolutionary interactions involving mammalian and avian seed predators. Analyses of population genetic variation are needed to determine whether this divergence has arisen despite extensive gene flow and whether populations to the east and west of the Rocky Mountains have evolved convergent phenotypes independently. Methods: We investigated genetic structuring across 22 stands of lodgepole pine in the central Rocky Mountains and in isolated peripheral populations that experience different seed predators and exhibit parallel divergence in cone traits using a set of nine simple sequence repeats and 235 AFLP loci. Key results: Our analyses reveal high levels of genetic diversity within and low genetic differentiation among populations. Nonetheless, geographic and genetic distances were correlated, and isolated populations to the east and west of the Rocky Mountains had higher levels of differentiation than did populations in the central part of the range. Conclusions: These data indicate not only that adaptive divergence of cone traits across a geographic mosaic of coevolution has occurred despite minimal genetic differentiation, but also that isolated populations to the east and west of the Rocky Mountains have evolved distinctive cones independently and in parallel. The population structure quantified here will inform future research aimed at detecting genetic variants associated with divergent adaptive traits.

description: Using machine learning with a variational formula for diffusivity, we recast diffusion as a sum of individual contributions to diffusion--called "kinosons"--and compute their statistical distribution to model a complex multicomponent alloy. Calculating kinosons is orders of magnitude more efficient than computing whole trajectories, and elucidates kinetic mechanisms for diffusion. The distribution of kinosons with temperature leads to new accurate analytic models for macroscale diffusivity. This combination of machine learning with diffusion theory promises insight into other complex materials.

description: Electron transfer between redox active proteins and mineral oxides is important in a variety of natural as well as technological processes, including electron transfer from dissimilatory metal-reducing bacteria to minerals. One of the pathways that could trigger electron transfer between proteins and minerals is redox-linked conformation change. We present electrochemical evidence that mitochondrial cytochrorne c (Mee) undergoes significant conformation change upon interaction with hematite and indiurn-tin oxide (ITO) surfaces. The apparent adsorption-induced conformation change causes the protein to become more reducing, which makes it able to transfer electrons to the hematite conduction band. Although Mcc is not a protein thought to be involved in interaction with mineral surfaces, it shares (or can be conformed so as to share) some characteristics with multiheme outer-membrane cytochromes thought to be involved in the transfer of electrons from dissimilatory iron-reducing bacteria to ferric minerals during respiration. We present evidence that a 10.1 kDa monohoeme cytochrorne isolated and purified from Acidiphilium cryptum, with properties similar to those of Mcc, also undergoes conformation change as a result of interaction with hematite surfaces.

description: No abstracts are to be cited without prior reference to the author.Edible crab (Cancer pagurus) fishing areas are distributed along the English east coast with significant fisheries offshore of North Norfolk and the River Humber. Previous tagging studies showed directed northerly movements of mature females suggesting that recruitment was strongly influenced by larval drift southwards. Comparison of results from a larvae survey undertaken in July 1999 with two previous surveys in 1976 and 1993 showed that the epicentre of crab spawning, as perceived by the density of stage I larvae, has remained consistent over the 23 year period, being centred to the south-west of The Dogger Bank approximately 70km offshore. Recent hydrographical evidence suggests that there is a seasonal jet-like circulation which extends southwards along the north-east coast of England as far as Flamborough Head before turning offshore along the northern edge of The Dogger Bank. The front forms in April/May and breaks down again in October/November, and once established there is very little interchange between water masses north and south of the Dogger Bank. South of the Dogger Bank the circulation is weak with only a slow easterly residual flow. The areas to the north and south of the front are effectively isolated during the period of crab spawning activity, challenging the accepted wisdom that the main crab fishery is reliant upon recruitment from spawning areas to the north. Indeed, the crab population south of the Dogger Bank may be a separate, self-sustaining stock providing recruitment of adult crabs to northern areas

description: The stochastic gravitational wave background for pulsar timing arrays is often modeled by a Gaussian ensemble which is isotropic and unpolarized. However, the Universe has a discrete set of polarized gravitational wave sources at specific sky locations. Can we trust that the Gaussian ensemble is an accurate description? To investigate this, we explicitly construct an ensemble containing $N$ individual binary sources with circular orbits. The orbital inclination angles are randomly distributed, hence the individual sources are elliptically polarized. We then compute the first two moments of the Hellings and Downs correlation, as well as the pulsar-averaged correlation mean and (cosmic) variance. The first moments are the same as for a previously studied ensemble of circularly polarized sources. However, the second moments, and hence the variances, are different for the two ensembles. While neither discrete source model is exactly described by a Gaussian ensemble, we show that in the limit of large $N$, the differences are small.

description: No abstracts are to be cited without prior reference to the author.PICES, the North Pacific Marine Science Organization, is an internationalorganization analogous in many ways to ICES - intergovernmental and devotedto promotion and coordination of marine scientific research in its oceanic region -and different in several ways including its present lack of advisory responsibilitiesin fishery management and environmental protection. From its first meeting,seven years ago, PICES has tried to compile scientific knowledge of the northernNorth Pacific and to identify research priorities, using standing committees,working groups and task teams similar to those of ICES. Many of the prioritiescoalesce around investigation of the effects of climate variations, at interannual(e.g., ENSO), decadal and interdecadal (e.g., regime shift) time scales onecosystems of the region. These interests led to initiation in 1994 of thePICESIGLOBEC program on Climate Change and Carrying Capacity, the so-calledFour Cs (CCCC) program. It was inspired by controversy over whether there wassome limit to the numbers of hatchery produced salmon that could beaccommodated at the oceanic feeding table but quickly spread to other featuresof ecosystem response to environmental change and to questions such as theimmutability of carrying capacity during climate regime shifts. The associationwith GLOBEC advances the PICES agenda. The same can be said of thedeveloping links with GOOS. Implementation of such interdisciplinary programsdepends fundamentally on the cooperative action of scientists and theirlaboratories and supporting agencies in the participating countries, tied togetherand facilitated by an international body such as PICES.

description: Deep neural networks have a good success record and are thus viewed as the best architecture choice for complex applications. Their main shortcoming has been, for a long time, the vanishing gradient which prevented the numerical optimization algorithms from acceptable convergence. A breakthrough has been achieved by the concept of residual connections -- an identity mapping parallel to a conventional layer. This concept is applicable to stacks of layers of the same dimension and substantially alleviates the vanishing gradient problem. A stack of residual connection layers can be expressed as an expansion of terms similar to the Taylor expansion. This expansion suggests the possibility of truncating the higher-order terms and receiving an architecture consisting of a single broad layer composed of all initially stacked layers in parallel. In other words, a sequential deep architecture is substituted by a parallel shallow one. Prompted by this theory, we investigated the performance capabilities of the parallel architecture in comparison to the sequential one. The computer vision datasets MNIST and CIFAR10 were used to train both architectures for a total of 6912 combinations of varying numbers of convolutional layers, numbers of filters, kernel sizes, and other meta parameters. Our findings demonstrate a surprising equivalence between the deep (sequential) and shallow (parallel) architectures. Both layouts produced similar results in terms of training and validation set loss. This discovery implies that a wide, shallow architecture can potentially replace a deep network without sacrificing performance. Such substitution has the potential to simplify network architectures, improve optimization efficiency, and accelerate the training process.

description: Complex geochemical reaction processes that occur within the tailings impoundments control the chemistry of resulting seepage or drainage water. In this dissertation, the second chapter focuses on simulating seepage water chemistry from the main sulphide tailings storage facility (TSF) around Kansanshi mine site in Zambia and its geochemical evolution in the underlying unconfined schist aquifer. The result of this study indicates that seepage water chemistry from the main sulphide TSF is likely to be within near neutral range (6.3 to 6.6) with elevated concentrations of sulphate and low concentration of Fe and Mn. The presence of calcite, dolomite and aluminosilicate minerals in the tailings helps to buffer the pH of the simulated seepage water within near neutral range favorable for the removal of metals from the solution through precipitation. Elevated sulphate levels in simulated seepage water results from the dissolution of both gypsum and pyrite. As the tailings water seeps into the shallow unconfined schist aquifer, geochemical simulations suggests that the presence of pyrite in the aquifer can moderately contribute to elevated concentrations of sulphate along the groundwater flow path with decreasing thickness of the capillary fringe or depth to water due to oxidation promoted by the increased rate of oxygen diffusion. The third chapter investigated the influence of fracture zones on solute (SO42-, Fe and Mn) transport from the main TSF using Equivalent Porous Media (EPM) approach, focusing on sulphate since it is the least reactive and can migrate far from the source. Two solute transport models were developed; one involving an EPM-only representation of the mapped fracture zones, and one including hypothetical fractures as high hydraulic conductivity zones to explore how unmapped fractures could impact solute transport. Results of the simulations revealed that only the model which incorporated hypothetical fractures to intersect wells that consistently show elevated sulphate concentrations show some degree of a match between the simulated and observed sulphate concentrations especially with boreholes KE03 and KE04 situated downstream of the main TSF, with the sulphate plume (>100mg/L) elongated along all fracture zones cutting across the dam. This demonstrates that fractures have a greater effect on solute transport than unfractured representation of the porous matrix, suggesting a simple EPM-based conceptual model may not be able to realistically represent transport behaviors in this system. However, in both cases, results from both solute transport models show that both Fe and Mn are restricted to the main TSF footprint and thus are not likely to be of concern from the facility.

description: We have presented the leading twist quark transverse momentum-dependent parton distribution functions (TMDs) for the spin-1 heavy vector mesons $J/ψ$-meson and $Υ$-meson using the overlap of the light-front wave functions. We have computed their TMDs in the light-front holographic model (LFHM) as well as the light-front quark model (LFQM) and further compared the results with the Bethe-Salpeter (BSE) model. We have discussed the behavior of the TMDs with respect to momentum fraction carried by active quark ($x$) and the transverse quark momenta ($k_\perp$) in both the models. We have also calculated the $k_\perp$ moments of the quark in both the models and have compared the results with the BSE model. The predictions of LFQM are found to be in accord with the BSE model. Further, we have analyzed the leading twist parton distribution functions (PDFs) for both the heavy mesons in both the models and the results are found to be in accord with the basic light-front quantization (BLFQ) and BSE model.

description: No abstracts are to be cited without prior reference to the author.The Burry Inlet in south Wales has supported a regionally important fishery for cockles for more than a century. Statistical analysis of survey data shows that annual variation in abundance is driven almost entirely by variation in settlement strength in autumn. Annual mortality varies between age-classes, falling from 60-70% during the first year of life to around 50% subsequently, but variation between calendar years is relatively unimportant in determining overall abundance levels. The Burry Inlet also supports internationally important concentrations of shorebirds, notably oystercatcher (Haematopus ostralegus), an important predator of adult cockles. A model of fishing and bird predation is constructed, using data on cockle stock abundance, fishery removals and bird numbers, and incorporating information on seasonal patterns of cockle growth and flesh content and feeding requirements of birds. The model is used to obtain estimates of the numbers of cockles at size and age taken by birds and fishermen. The results show that there is a relatively small overlap between birds and fishing in the sizes of cockles taken birds take a relatively large number, but small biomass of smaller cockles. Fishing and bird predation appear to be additive to each other as sources of mortality, but to be compensated for by changes in other (unknown) sources of mortality. After accounting for bird predation, fishing would appear not to increase overall cockle mortality provided that it takes no more than 30-40% of the overall abundance. The applicability of this finding to other cockle fisheries is discussed.

description: By integrating across the light-cone energy, totally unintegrated, off-diagonal quark-quark generalized parton correlation functions (GPCFs) can yield generalized transverse-momentum dependent parton distributions (GTMDs). We have obtained the twist-4 GTMDs for the case of proton in the light-front quark-diquark model (LFQDM). We have decoded the quark-quark GTMD correlator for proton and solved the parametrization equations for Dirac matrix structure at twist-4. We have derived the explicit equations of GTMDs for the diquark being scalar or vector leading to the results for the struck quark being a $u$ or $d$ quark. Being a multidimensional function, the dependence is studied with two variables at a time, keeping the others fixed. Transverse-momentum dependent form factors (TMFFs) have been obtained from GTMDs via integration over the longitudinal momentum fraction $x$ of the quark. We have debated over the possibility to specify the initial and final state polarizations of the smacked quark and the nucleon in twist-4 GTMDs as well as the Wigner distributions. Additionally, from twist-4 GTMDs, we have deduced the twist-4 T-even TMDs and found its synchronization with the already published results.

description: The brain is remarkably adept at learning from a continuous stream of data without significantlyforgetting previously learnt skills. Conventional machine learning models struggle at continual learn-ing, as weight updates that optimize the current task interfere with previously learnt tasks. A simpleremedy to catastrophic forgetting is freezing a network pretrained on a set of base tasks, and trainingtask-specific readouts on this shared trunk. However, this assumes that representations in the frozennetwork are separable under new tasks, therefore leading to sub-par performance. To continually learnon novel task data, previous methods suggest weight consolidation – preserving weights that are mostimpactful for the performance of previous tasks – and memory-based approaches – where the networkis allowed to see a subset of images from previous tasks.For biological networks, prior work showed that dendritic top-down modulations provide a powerfulmechanism to learn novel tasks while initial feedforward weights solely extract generic view-invariantfeatures. Therefore, we propose a continual learner that optimizes the feedforward weights towardsview-invariant representations while training task-specific modulations towards separable class clus-ters. In a task-incremental setting, we train feedforward weights using a self-supervised algorithm,while training the task-specific modulations and readouts in a supervised fashion, both exclusivelythrough current-task data. We show that this simple approach avoids catastrophic forgetting of classclusters, as opposed to training the whole network in a supervised manner, while also outperforming(a) task-specific readout without modulations and (b) frozen feedforward weights. This suggests that(a) top-down modulations are necessary and sufficient to shift the representations towards separableclusters and that (b) the SSL objective learns novel features based on the newly presented objectswhile maintaining features relevant to previous tasks, without requiring specific synaptic consolidationmechanisms.

description: No abstracts are to be cited without prior reference to the author.Cod is a determinate spawner, with a high potential fecundity. That is, a large definite number of oocytes start maturing prior to spawning. Environmental factors, such as water temperature and food availability have strong effects on nutritional status and fish size. Accumulation of energy prior to spawning is important, as food intake during spawning is minimum. Fecundity is a changeable process that can be adjusted to the condition of the fish. Under favorable circumstances potential fecundity may be equivalent to the number of eggs spawned during the spawning season. When the environmental conditions are unfavorable some or all, developing oocytes included in the potential fecundity estimate may be lost through resorption from the ovary, a process known as atresia. Atresia seems mainly to be initiated under low nutritional status prior to spawning. The relationship between atresia and oocyte diameter is negatively related. As the oocyte diameter increases during the spawning season, occurrence of atresia decreases.

description: Nambu Quantum Mechanics, proposed in Phys. Lett. B536, 305 (2002), is a deformation of canonical Quantum Mechanics in which the manifold over which the "phase" of an energy eigenstate time evolves is modified. This generalization affects oscillation and interference phenomena through the introduction of two deformation parameters that quantify the extent of deviation from canonical Quantum Mechanics. In this paper, we constrain these parameters utilizing atmospheric neutrino oscillation data, and $B^0$-$\overline{B^0}$ oscillation data from Belle. Surprisingly, the bound from atmospheric neutrinos is stronger than the bound from Belle. Various features of Nambu Quantum Mechanics are also discussed.

description: We construct Quillen equivalent semi-model structures on the categories of dg-Lie algebroids and $L_\infty$-algebroids over a commutative dg-algebra in characteristic zero. This allows one to apply the usual methods of homotopical algebra to dg-Lie algebroids: for example, every Lie algebroid can be resolved by dg-Lie algebroids that arise from dg-Lie algebras, i.e. that have a null-homotopic anchor map. As an application, we show how Lie algebroid cohomology is represented by an object in the homotopy category of dg-Lie algebroids.

description: Voxel-based multiple testing is widely used in neuroimaging data analysis. Traditional false discovery rate (FDR) control methods often ignore the spatial dependence among the voxel-based tests and thus suffer from substantial loss of testing power. While recent spatial FDR control methods have emerged, their validity and optimality remain questionable when handling the complex spatial dependencies of the brain. Concurrently, deep learning methods have revolutionized image segmentation, a task closely related to voxel-based multiple testing. In this paper, we propose DeepFDR, a novel spatial FDR control method that leverages unsupervised deep learning-based image segmentation to address the voxel-based multiple testing problem. Numerical studies, including comprehensive simulations and Alzheimer's disease FDG-PET image analysis, demonstrate DeepFDR's superiority over existing methods. DeepFDR not only excels in FDR control and effectively diminishes the false nondiscovery rate, but also boasts exceptional computational efficiency highly suited for tackling large-scale neuroimaging data.

description: No abstracts are to be cited without prior reference to the author.In formulating stock assessment models for stocks of sedentary species, it is important to have a good understanding of stock spatial structure and distribution. Scallops are an example of a species that is patchily distributed over its grounds, with implications for interpretation of fishery statistics. We describe the results of experimental fishing for scallops in the western English Channel, aimed at identifying the spatial scales at which catch rates and abundance vary. An hierarchical survey design was used to examine catch rate variation at scales from 101 to 104 m. Catch rates at 54 locations grouped into six areas within two ICES rectangles varied from 0 to 148 scallops per dredge ha. Approximately equal amounts of variation were attributable to each level of the spatial hierarchy. Catch rates were strongly correlated with ground type, being almost 20 times higher on hard than soft ground. Subsequent depletion fishing showed that around half the variation in catch rates was due to differences in abundance between areas. The remaining variation was due to differences in gear performance. Gear efficiency varied between 8% on soft ground to 51% on hard ground. Future analysis of log-book data from scallop vessels will allow us to describe how targeting of fishing effort relates to these spatial patterns, and thus enable us to identify the appropriate spatial scale at which to consider fishery sampling data for stock assessment.

description: Physozetes gen. n.    Diagnosis: Rostrum rounded, bearing short flagellate rostral setae. Rostral part covered by the inflated anterodorsal prodorsum. Lamellae comparatively small, with sharp inner and outer apices. Its median part finely serrated. A narrow translamella present basally. Lamellar setae arising from the basal part of the lamellae; interlamellar setae inserted on the lamellar surface, very long, flagellate. Sensillus long, setiform, directed backwards. Dorsosejugal suture slightly concave; pteromorphae very large. All notogastral setae fine, flagellate. Sejugal and 4th apodemata long and strong, compose a well discernible X-shaped formation in front of the genital aperture. Except for the long genital setae g 1, all setae in this region short and fine.
 Type species: Physozetes inflatus sp. n.
 Remarks: Excepting the direction of the sensillus, the new taxon stands nearest to the genus Schalleria BALOGH, 1962. However on the basis of the form and direction of the sensillus, the form of the dorsosejugal suture and the formation of the apodemata, the new taxon is similar to the genus Teraja MAHUNKA, 1995. The new taxon is different from these and also from Caucasiozetes STANCHAEVA, 1984 by the position of the interlamellar setae and the X-shaped formation of the sejugal and 4th apodemata and bordures of the epimeral region.
