description: Biodiversity–ecosystem function (BEF) experiments routinely employ common garden designs, drawing samples from a local biota. The communities from which taxa are sampled may not, however, be at equilibrium. To test for temporal changes in BEF relationships, I assembled the pools of aquatic bacterial strains isolated at different time points from leaves on the pitcher plant Darlingtonia californica in order to evaluate the strength, direction and drivers of the BEF relationship across a natural host-associated successional gradient. I constructed experimental communities using bacterial isolates from each time point and measured their respiration rates and competitive interactions. Communities assembled from mid-successional species pools showed the strongest positive relationships between community richness and respiration rates, driven primarily by linear additivity among isolates. Diffuse competition was common among all communities but greatest within mid-successional isolates. These results demonstrate the dependence of the BEF relationship on the temporal dynamics of the local species pool, implying that ecosystems may respond differently to the addition or removal of taxa at different points in time during succession.

description: We present an integrated scheme for dielectric drive and read-out of high-Q nanomechanical resonators which enables tuning of both the resonance frequency and quality factor with an applied DC voltage. A simple model for altering these quantities is derived, incorporating the resonator's complex electric polarizability and position in an inhomogeneous electric field, which agrees very well with the experimental findings as well as FEM simulations. By comparing two sample geometries we are able to show that careful electrode design can determine the direction of frequency tuning of flexural in- and out-of-plane modes of a string resonator. Furthermore we demonstrate that the mechanical quality factor can be voltage reduced more than fivefold.

description: Intraspecific coevolution between selfish elements and suppressors may promote interspecific hybrid incompatibility, but evidence of this process is rare. Here, we use genomic data to test alternative models for the evolution of cytonuclear hybrid male sterility in Mimulus. In hybrids between Iron Mountain (IM) Mimulus guttatus × M. nasutus, two tightly linked M. guttatus alleles (Rf1/Rf2) each restore male fertility by suppressing a local mitochondrial male-sterility gene (IM-CMS). Unlike neutral models for the evolution of hybrid incompatibility loci, selfish evolution predicts that the Rf alleles experienced strong selection in the presence of IM-CMS. Using whole-genome sequences, we compared patterns of population-genetic variation in Rf at IM to a neighbouring population that lacks IM-CMS. Consistent with local selection in the presence of IM-CMS, the Rf region shows elevated FST, high local linkage disequilibrium and a distinct haplotype structure at IM, but not at CP, suggesting a recent sweep in the presence of IM-CMS. In both populations, Rf2 exhibited lower polymorphism than other regions, but the low-diversity outliers were different between CP and IM. Our results confirm theoretical predictions of ubiquitous cytonuclear conflict in plants and provide a population-genetic mechanism for the evolution of a common form of hybrid incompatibility.

description: Let $A$ be a local Noetherian domain of Krull dimension $d$. Heinzer, Rotthaus and Sally have shown that if the generic formal fiber of $A$ has dimension $d-1$, then $A$ is birationally dominated by a one-dimensional analytically ramified local Noetherian ring having residue field finite over the residue field of $A$. We explore further this correspondence between prime ideals in the generic formal fiber and one-dimensional analytically ramified local rings. Our main focus is on the case where the analytically ramified local rings are stable, and we show that in this case the embedding dimension of the stable ring reflects the embedding dimension of a prime ideal maximal in the generic formal fiber, thus providing a measure of how far the generic formal fiber deviates from regularity. A number of characterizations of analytically ramified local stable domains are also given.

description:
Ikaite is an essential calcium carbonate mineral especially in cold regions of Earth. However, the conditions leading to the formation of ikaite are poorly constrained. In a previous study (Chaka 2018), it was reported that the nucleation mechanism of ikaite likely does not compare to widely recognized mechanisms of more stable anhydrous CaCO3-minerals. Nucleation was rather attributed to a low energy pathway, which leads to the highly hydrated ikaite structure by assembling aqueous ion pair complexes. Whether such a nucleation mechanism is affected by foreign surfaces, as it was already shown for the formation of anhydrous calcium carbonate minerals (Li et al. 2014), remained unclear so far. This lack of knowledge is particularly serious as a better understanding of the nucleation of ikaite in presence of mineral surfaces could lead to profound insights of ikaite formation under natural conditions. In our study, new data on ikaite formation in presence of mineral surfaces were gained from cryo-mixed-batch-reactor and cryo-AFM experiments using quartz and mica surfaces as proxies for natural settings. Our experiments revealed similar effects of the presence of quartz and mica on ikaite nucleation. Both minerals caused a significant expansion of the supersaturation range from which ikaite forms instead of calcite or vaterite. For ikaite formation, therefore, the presence of mineral surfaces is at least as important as calcite-inhibiting substances. The latter, so far, were the only ikaite promoters recognized in natural settings. Furthermore, our results revealed low interfacial energies which imply a nucleation mechanism including a minimal energy barrier.

description: The southern Mid-Atlantic Bight (MAB) near Cape Hatteras, NC, USA, is likely a hotspot for the episodic export of carbon-rich shelf waters to the open ocean. Over a 2 year period, from March 2017 to May 2019, Spray gliders repeatedly occupied transects, along the slope and across the shelf, generating high-resolution chlorophyll fluorescence (fChl) data in the southern MAB. This study implements an fChl calibration method utilizing remotely sensing ocean color as a standard. We validate the method’s utility by demonstrating a reduction in post-calibration cross-mission fChl variability and demonstrating close correspondence between the calibrated fChl data and an in situ chlorophyll measurements. Using the calibrated fChl data, we calculate the mean and standard deviation of fChl for the study region on both annual and seasonal time scales. In general, we found that fChl concentrations were highest in the winter-spring season, followed by the summer, with the lowest mean fChl observed in fall. Spatially, high mean concentrations of fChl are associated with a relatively greater chlorophyll at depth in spring-winter, from the surface down to 250 m. High mean concentrations of fChl are confined to a subsurface layer from 10 m to 40 m in the summer, and fall’s highest mean concentrations of fChl are found in the top 50 m in fall. The highest variability in fChl was observed in the winter-spring season, with peaks near the surface and between 150m and 250m at the southern end of the slope transect, near the Gulf Stream wall. We interpret this high variability in fChl as an indication that episodic fluxes of high chlorophyll concentrations, termed as “deep chlorophyll events”, may be occurring in this location. To support this idea, we identified 10 individual deep chlorophyll events based on fChl (> 0.75 mg m-3) and depth (>100m) thresholds and found that the events occurred primarily in winter-spring; with a small number also identified in summer and none in fall; and have similarities with previously recognized mechanisms of shelf water cascade dynamics and MAB cold pool export.

description: Ultrarelativistic charged particles are predicted to emit hard electromagnetic radiation of undulator type while being channeled in a crystal with periodically bent crystallographic planes. The recently proposed crystalline undulator with the bending amplitude smaller than the distance between the bent planes and the bending period shorter than the period of channeling oscillations is far superior to what was proposed previously. In the same time, it is more challenging from the technical point of view because its bending period has to be in the sub-micron range. It is shown that a mixed crystal of silicon-germanium with properly varying germanium fraction can have the necessary bending parameters. Moreover, it is predicted to be stable against misfit dislocations.

description: We present a nuclear medical imaging technique, employing triple-gamma trajectory intersections from beta^+ - gamma coincidences, able to reach sub-millimeter spatial resolution in 3 dimensions with a reduced requirement of reconstructed intersections per voxel compared to a conventional PET reconstruction analysis. This '$γ$-PET' technique draws on specific beta^+ - decaying isotopes, simultaneously emitting an additional photon. Exploiting the triple coincidence between the positron annihilation and the third photon, it is possible to separate the reconstructed 'true' events from background. In order to characterize this technique, Monte-Carlo simulations and image reconstructions have been performed. The achievable spatial resolution has been found to reach ca. 0.4 mm (FWHM) in each direction for the visualization of a 22Na point source. Only 40 intersections are sufficient for a reliable sub-millimeter image reconstruction of a point source embedded in a scattering volume of water inside a voxel volume of about 1 mm^3 ('high-resolution mode'). Moreover, starting with an injected activity of 400 MBq for ^76Br, the same number of only about 40 reconstructed intersections are needed in case of a larger voxel volume of 2 x 2 x 3~mm^3 ('high-sensitivity mode'). Requiring such a low number of reconstructed events significantly reduces the required acquisition time for image reconstruction (in the above case to about 140 s) and thus may open up the perspective for a quasi real-time imaging.

description: The wavelength switching dynamics of two-colour semiconductor lasers with optical injection and feedback are presented. These devices incorporate slotted regions etched into the laser ridge waveguide for tailoring the output spectrum. Experimental measurements are presented demonstrating that optical injection in one or both modes of these devices can induce wavelength bistability. Measured switching dynamics with modulated optical injection are shown to be in excellent agreement with numerical simulations based on a simple rate equation model. We also demonstrate experimentally that time-delayed optical feedback can induce wavelength bistability for short external cavity lengths. Numerical simulations indicate that this two-colour optical feedback system can provide fast optical memory functionality based on injected optical pulses without the need for an external holding beam.

description: Magnetic susceptibility and muon spin relaxation (muSR) experiments have been carried out on the quasi-2D triangular-lattice spin S = 2 antiferromagnet FeGa2S4. The muSR data indicate a sharp onset of a frozen or nearly-frozen spin state at T* = 31(2) K, twice the spin-glass-like freezing temperature T_f = 16(1) K. The susceptibility becomes field dependent below T*, but no sharp anomaly is observed in any bulk property. A similar transition is observed in muSR data from the spin-1 isomorph NiGa2S4. In both compounds the dynamic muon spin relaxation rate lambda_d(T) above T* agrees well with a calculation of spin-lattice relaxation by Chubukov, Sachdev, and Senthil in the renormalized classical regime of a 2D frustrated quantum antiferromagnet. There is no firm evidence for other mechanisms. At low temperatures lambda_d(T) becomes temperature independent in both compounds, indicating persistence of spin dynamics. Scaling of lambda_d(T) between the two compounds is observed from ~T_f to ~1.5T*. Although the muSR data by themselves cannot exclude a truly static spin component below T*, together with the susceptibility data they are consistent with a slowly-fluctuating "spin gel" regime between T_f and T*. Such a regime and the absence of a divergence in lambda_d(T) at T* are features of two unconventional mechanisms: (1) binding/unbinding of Z_2 vortex excitations, and (2) impurity spins in a nonmagnetic spin-nematic ground state. The absence of a sharp anomaly or history dependence at T* in the susceptibility of FeGa2S4, and the weakness of such phenomena in NiGa2S4, strongly suggest transitions to low-temperature phases with unconventional dynamics.

description: Ecosystems are linked to neighbouring ecosystems not only by dispersal, but also by the movement of subsidy. Such subsidy couplings between ecosystems have important landscape-scale implications because perturbations in one ecosystem may affect community structure and functioning in neighbouring ecosystems via increased/decreased subsidies. Here, we combine a general theoretical approach based on harvesting theory and a two-patch protist meta-ecosystem experiment to test the effect of regional perturbations on local community dynamics. We first characterized the relationship between perturbation regime and local population demography on detritus production using a mathematical model. We then experimentally simulated a perturbation gradient affecting connected ecosystems simultaneously, thus altering cross-ecosystem subsidy exchanges. We demonstrate that the perturbation regime can interact with local population dynamics to trigger unexpected temporal variations in subsidy pulses from one ecosystem to another. High perturbation intensity initially led to the highest level of subsidy flows; however, the level of perturbation interacted with population dynamics to generate a crash in subsidy exchange over time. Both theoretical and experimental results show that perturbation regime interacting with local community dynamics can induce a collapse in population levels for recipient ecosystems. These results call for an integrative management of human-altered landscapes that takes into account regional dynamics of both species and resource flows.

Paired positive carbonate carbon isotope, organic carbon isotope, and oxygen isotope composition study across the Lower Mississippian positive carbon isotope excursion, southeastern Nevada, USA
Creators: name: Henry, Robert Alan
Publisher: name: University of Nevada, Las Vegas
Year: 2011

description: A prominent positive carbonate carbon isotope (delta13Ccarb) excursion of Early Mississippian age (ca 351 Ma) has been documented by previous studies from numerous sites globally. This delta13Ccarb excursion has been interpreted as resulting from enhanced organic carbon burial that removed 13C-depleted carbon from the ocean and atmosphere. Anticipated outcomes from enhanced organic carbon burial would include a similar positive excursion in organic carbon isotopes (delta13Corg) and a global cooling event resulting from reduced CO2 in the atmosphere and ocean. These predictions, however, were not tested sufficiently in previous studies. This research has tested these predictions through an integrated study of carbonate, and organic carbon, and oxygen isotopes in two Lower Mississippian stratigraphic sections in southeastern Nevada: the Alamo section and the Tungsten Gap section.
Paired delta13Corg and delta13Ccarb analyses and brachiopod oxygen isotope analysis across the positive delta13Ccarb excursion show that (1) delta13Ccarb and delta13Corg values are coupled in the Alamo section, but considerable variations in both delta13Ccarb and delta13Corg values are present in the Tungsten Gap section; (2) delta18O values of limestone matrix and brachiopods show an overall increase across the delta13C excursion, but increase in deltaO predates the delta13C maximum. A significant negative shift in delta18O from -5 per mil to -21 per mil is observed before the delta13C peak; and (3) carbonate and organic carbon isotope fractionation, approximated by the isotope difference (DELTA13C) between delta13Ccarb and delta13Corg (DELTA13C = delta13Ccarb - delta13Corg) increases from 26 per mil to 31 per mil before the DELTA13C peak, but remains about 31 per mil for the remainder of the excursion interval.
Overall, the data support enhanced organic production and burial as the origin of the DELTA13C excursion, but the cooling event occurred earlier than the peak of the carbon isotope excursion. The lack of change in both delta18O and DELTA13C across the later half of DELTA13C excursion suggests that, after the initial cooling at the beginning of the DELTA13C excursion, seawater temperature and aqueous CO2 concentration did not change significantly. Unresolved is the cause of isotopic difference between the Alamo and Tungsten Gap sections. More scattered and lower values in delta13Ccarb, delta13Corg, and delta18O from the Tungsten Gap section may imply a significant influence from terrestrial sediment sources or freshwater input, but considering the paleogeographic location of section, the later is more likely. Further elucidating the isotope difference between sections requires higher sampling resolution from the Tungsten Gap section and from other sections further eastward in proximal environments of the early Mississippian carbonate platform.

description:
Construction waste (CW) from demolished buildings delivers a vast amount of resources for recycling material (RCM). RCM can be used as gravel, recycling-concrete or potentially for more precious applications. Hazardous pollutants in CW, like asbestos, threaten this applications, regarding health and environmental risks. Risks for human health induced by asbestos fibres, like asbestosis and mesothelioma are well known. The industrially used mineral asbestos has contaminated many parts within buildings (e.g. floor, ceiling, roof, seals, etc.) and technical constructions and products. Once, the asbestos-containing materials (ACM) reach the construction waste, the recognition of ACM becomes quite difficulty and time consuming. In the first instance we are developing a manual including attributes of different ACM to identify them on site, within the possibly very heterogenic CW. Additionally we are conducting experiments using modelled piles of CW in order to better understand the presence and visibility of ACM in piles. Here the appearance of ACM-substitutes is counted on the surface of modelled piles. The grain size distribution of demolished ACM will be quantified and analysed accordingly, to understand which amounts and distributions of particles of ACM may contaminate the CW. This may potentially be utilised to support the development of methods for the removal of ACM from CW.

The obtained results will lead to a better understanding of ACM in CW, which will increase and ensure the quality of RCM.

description: Cosmological models with Lagrange multipliers are appealing because they could explain the behaviour of the dark sector in a unified way. In this work we analyse extensions to the "Dust of Dark Energy model" proposed in arXiv:1003.5751 by including spatial curvature and more general potentials of the scalar field. We perform dynamical system analysis and we determine the evolution of the equation of state parameter as a function of the scale factor. We present observational constraints on this model by using Union2.1 dataset and H(z) data.

description: There is significant recent interest in Peto's paradox and the related problem of the evolution of large, long-lived organisms in terms of cancer robustness. Peto's paradox refers to the expectation that large, long-lived organisms have a higher lifetime cancer risk, which is not the case: a paradox. This paradox, however, is circular: large, long-lived organisms are large and long-lived because they are cancer robust. Lifetime risk, meanwhile, depends on the age distributions of both cancer and competing risks: if cancer strikes before competing risks, then lifetime risk is high; if not, not. Because no set of competing risks is generally prevalent, it is instructive to temporarily dispose of competing risks and investigate the pure age dynamics of cancer under the multistage model of carcinogenesis. In addition to augmenting earlier results, I show that in terms of cancer-free lifespan large organisms reap greater benefits from an increase in cellular cancer robustness than smaller organisms. Reversely, a higher cellular cancer robustness renders cancer-free lifespan more resilient to an increase in size. This interaction may be an important driver of the evolution of large, cancer robust organisms.

description: We present a mathematical model, and the corresponding mathematical analysis, that justifies and quantifies the use of principal component analysis of biallelic genetic marker data for a set of individuals to detect the number of subpopulations represented in the data. We indicate that the power of the technique relies more on the number of individuals genotyped than on the number of markers.

description: Remaining undetected is often key to survival, and camouflage is a widespread solution. However, extrinsic to the animal itself, the complexity of the background may be important. This has been shown in laboratory experiments using artificially patterned prey and backgrounds, but the mechanism remains obscure (not least because ‘complexity’ is a multifaceted concept). In this study, we determined the best predictors of detection by wild birds and human participants searching for the same cryptic targets on trees in the field. We compared detection success to metrics of background complexity and ‘visual clutter’ adapted from the human visual salience literature. For both birds and humans, the factor that explained most of the variation in detectability was the textural complexity of the tree bark as measured by a metric of feature congestion (specifically, many nearby edges in the background). For birds, this swamped any effects of colour match to the local surround, although, for humans, local luminance disparities between the target and tree became important. For both taxa, a more abstract measure of complexity, entropy, was a poorer predictor. Our results point to the common features of background complexity that affect visual search in birds and humans, and how to quantify them.

description: Chewing, characterized by shearing jaw motions and high-crowned molar teeth, is considered an evolutionary innovation that spurred dietary diversification and evolutionary radiation of mammals. Complex prey-processing behaviours have been thought to be lacking in fishes and other vertebrates, despite the fact that many of these animals feed on tough prey, like insects or even grasses. We investigated prey capture and processing in the insect-feeding freshwater stingray, Potamotrygon motoro, using high-speed videography. We find that Potamotrygon motoro uses asymmetrical motion of the jaws, effectively chewing, to dismantle insect prey. However, CT-scanning suggests that this species has simple teeth. These findings suggest that in contrast to mammalian chewing, asymmetrical jaw action is sufficient for mastication in other vertebrates. We also determined that prey capture in these rays occurs through rapid uplift of the pectoral fins, sucking prey beneath the ray's body and dissociates the jaws from a prey capture role. We suggest that the decoupling of prey capture and processing facilitated the evolution of a highly kinetic feeding apparatus in batoid fishes, giving these animals an ability to consume a wide variety of prey, including molluscs, fishes, aquatic insect larvae, and crustaceans. We propose Potamotrygon as a model system for understanding evolutionary convergence of prey processing and chewing in vertebrates.

description: We report the first observation of Shubnikov-de Haas (SdH) oscillations and quantized Hall resistance in the multilayered massless Dirac fermion system $α$-(BEDT-TTF)$_2$I$_3$ with tilted cones. Holes were injected into the thin crystal fixed on a polyethylene naphthalate (PEN) substrate by contact electrification. The detection of SdH oscillations whose phase was modified by Berry's phase $π$ strongly suggested that the carrier doping was successful in this system. We succeeded in detecting the quantum Hall effect (QHE) with the steps which is the essence of two dimensional Dirac fermion systems. The number of effectively doped layers was examined to be two in this device. We reveal that the correlation between effective layers plays an important role in QHE.

Effective Valence Quark Model and a Possible Dip in $d Br(B \to K \ell \bar{\ell})/dq^2$

description: In rare $B$ meson decays $B\rightarrow K \ell^+ \ell^-$, a possible contribution of $\ell^+\ell^-$ emission via photon from the "spectator" quark $q$ ($q=u,d$) in the $B$ meson $(q\bar{b})$ is investigated in addition to the conventional one $\bar{b} \rightarrow \bar{s} +γ\rightarrow \bar{s}+\ell^+ + \ell^-$. If such a contribution is sizable compared with the standard estimation of $B\rightarrow K \ell^+ \ell^-$, we will observe visible difference between $d Γ(B^0\rightarrow K^0 \ell^+ \ell^-)/d q^2$ and $d Γ(B^+\rightarrow K^+ \ell^+ \ell^-)/d q^2$ in $q^2$ dependence ($q^2 \equiv m_{\ell\ell}^2$). Besides, as a result of the interference between the conventional one and a new one, a dip appears in $d Γ(B\rightarrow K \ell^+ \ell^-)/d q^2$ at a small region of $q^2$. The interference effect in the $B^0$ decay will also be observed differently from that in the $B^+$ decay. The calculation is done based on a semi-classical approach, a valence quark model. In the present model, the photon emission from the spectator quark $q$, $d \rightarrow d+γ$ ($u \rightarrow u+γ$) is independent of the $b$-$s$ transition mechanism, and the characteristic results are due to a straightforward estimate of the quark propagator which cannot be incorporated into the factorization method. The model is not a valence quark "dominant" model, so that, for example, the valence quarks in the final state carry only $24\%$ of the energy-momentum of the kaon.

description: Muscle contractions that load in-series springs with slow speed over a long duration do maximal work and store the most elastic energy. However, time constraints, such as those experienced during escape and predation behaviours, may prevent animals from achieving maximal force capacity from their muscles during spring-loading. Here, we ask whether animals that have limited time for elastic energy storage operate with springs that are tuned to submaximal force production. To answer this question, we used a dynamic model of a muscle–spring system undergoing a fixed-end contraction, with parameters from a time-limited spring-loader (bullfrog: Lithobates catesbeiana) and a non-time-limited spring-loader (grasshopper: Schistocerca gregaria). We found that when muscles have less time to contract, stored elastic energy is maximized with lower spring stiffness (quantified as spring constant). The spring stiffness measured in bullfrog tendons permitted less elastic energy storage than was predicted by a modelled, maximal muscle contraction. However, when muscle contractions were modelled using biologically relevant loading times for bullfrog jumps (50 ms), tendon stiffness actually maximized elastic energy storage. In contrast, grasshoppers, which are not time limited, exhibited spring stiffness that maximized elastic energy storage when modelled with a maximal muscle contraction. These findings demonstrate the significance of evolutionary variation in tendon and apodeme properties to realistic jumping contexts as well as the importance of considering the effect of muscle dynamics and behavioural constraints when considering energy storage in muscle–spring systems.

\section{Conclusion} We have established a bridge between Koszul complexes and Plucker numbers, which allows us to efficiently construct local networks with high accuracy. This new relation also allows for the prediction and classification of various topological geometric structures in category theory, and the Planchifold theorem provides a framework for modeling the boundary behavior of these structures. We have also discussed the use of a simple iterative design model to construct universal mathematical constructs by combining homotopically meaningful flows and abstract hierarchical modeling.

description: We prove the immediate appearance of a lower bound for mild solutions to the full Boltzmann equation in the torus or a $C^2$ convex domain with specular boundary conditions, under the sole assumption of continuity away from the grazing set of the solution. These results are entirely constructive if the domain is $C^3$ and strictly convex. We investigate a wide range of collision kernels, some satisfying Grad's cutoff assumption and others not. We show that this lower bound is exponential, independent of time and space with explicit constants depending only on the \textit{a priori} bounds on the solution. In particular, this lower bound is Maxwellian in the case of cutoff collision kernels. A thorough study of characteristic trajectories, as well as a geometric approach of grazing collisions against the boundary are derived.
