description: We present a complete census of RR Lyrae stars in a halo field of the Andromeda galaxy. These deep observations, taken as part of a program to measure the star formation history in the halo, spanned a period of 41 days with sampling on a variety of time scales, enabling the identification of short and long period variables. Although the long period variables cannot be fully characterized within the time span of this program, the enormous advance in sensitivity provided by the Advanced Camera for Surveys on the Hubble Space Telescope allows accurate characterization of the RR Lyrae population in this field. We find 29 RRab stars with a mean period of 0.594 days, 25 RRc stars with a mean period of 0.316 days, and 1 RRd star with a fundamental period of 0.473 days and a first overtone period of 0.353 days. These 55 RR Lyrae stars imply a specific frequency S_RR=5.6, which is large given the high mean metallicity of the halo, but not surprising given that these stars arise from the old, metal-poor tail of the distribution. This old population in the Andromeda halo cannot be clearly placed into one of the Oosterhoff types: the ratio of RRc/RRabc stars is within the range seen in Oosterhoff II globular clusters, the mean RRab period is in the gap between Oosterhoff types, and the mean RRc period is in the range seen in Oosterhoff I globular clusters. The periods of these RR Lyraes suggest a mean metallicity of [Fe/H]=-1.6, while their brightness implies a distance modulus to Andromeda of 24.5+/-0.1, in good agreement with the Cepheid distance.

description: We analyze the problem of the beam-plasma instability via the analytical treatment of the so-called Dyson equation. We first compared the prediction of the model constructed by fixing the electric field amplitude with respect to a N-body Hamiltonian numerical simulation. Then, we demonstrate that the shortcomings of such an analytical formulation must be essentially identified with the breaking-down of the self-consistent evolution of the field and the particle distribution function.

description: Tracking behavioral and demographic changes of anuran populations in urban landscapes presents difficulties due to the high amount of noise interference from anthropogenic sources. In this study, we used Song Scope software to build narrow-banded recognizers that only cover a limited portion of the full spectral range of a call and tested if these recognizers can improve automated call-detection capabilities at noisy sites. We built recognizers for two species with naturally broad-spectrum calls, the Green Frog (Lithobates clamitans) and American Bullfrog (L. catesbeianus) and tested them at five noisy ponds in the suburbs of Chicago, Illinois, USA. Narrow-banded recognizers had greater percentages of true positives compared to full-spectrum recognizers. Classification indices used to assess call recognition efficacy showed that narrow-banded recognizers were more effective at all sites for the Green Frog, and at two sites for the American Bullfrog. High-frequency recognizers had 13% fewer errors caused by anthropogenic noise (P < 0.010) than other recognizers. Finally, for every recognizer, true positives standardized by the maximum daily value was highly and significantly correlated with the number of calls identified manually, indicating that automated detection data is an accurate proxy for the actual number of calls at noisy sites. For acoustic taxa, we recommend that scientists consider identifying broad-spectrum calls using narrow-banded recognizers to reduce detection problems associated with noise interference between anthropogenic noises and biotic acoustic signals.

description: Two major types of species richness patterns are spatial (e.g. the latitudinal diversity gradient) and clade-based (e.g. the dominance of angiosperms among plants). Studies have debated whether clade-based richness patterns are explained primarily by larger clades having faster rates of species accumulation (speciation minus extinction over time; diversification-rate hypothesis) or by simply being older (clade-age hypothesis). However, these studies typically compared named clades of the same taxonomic rank, such as phyla and families. This study design is potentially biased against the clade-age hypothesis, since clades of the same rank may be more similar in age than randomly selected clades. Here, we analyse the causes of clade-based richness patterns across the tree of life using a large-scale, time-calibrated, species-level phylogeny and random sampling of clades. We find that within major groups of organisms (animals, plants, fungi, bacteria, archaeans), richness patterns are most strongly related to clade age. Nevertheless, weaker relationships with diversification rates are present in animals and plants. These overall results contrast with similar large-scale analyses across life based on named clades, which showed little effect of clade age on richness. More broadly, these results help support the overall importance of time for explaining diverse types of species richness patterns.

description: A normal (non-superconducting) ground state of the t-J model may be variationally approximated by a Gutzwiller-projected wave function. Within this approximation, at small hole doping near half-filling, the normal state favors staggered-flux ordering. Such a staggered-flux state may occur in vortex cores of underdoped high-temperature cuprate superconductors. From comparing the energies of the staggered-flux state and of the superconducting state, we numerically obtain the condensation energy. Extracting the superfluid density directly from the projected superconducting wave function, we can also estimate the coherence length at zero temperature.

New semi-analytical solutions for advection-dispersion equations in multilayer porous media
Creators: name: Carr, Elliot J.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: A new semi-analytical solution to the advection-dispersion-reaction equation for modelling solute transport in layered porous media is derived using the Laplace transform. Our solution approach involves introducing unknown functions representing the dispersive flux at the interfaces between adjacent layers, allowing the multilayer problem to be solved separately on each layer in the Laplace domain before being numerically inverted back to the time domain. The derived solution is applicable to the most general form of linear advection-dispersion-reaction equation, a finite medium comprising an arbitrary number of layers, continuity of concentration and dispersive flux at the interfaces between adjacent layers and transient boundary conditions of arbitrary type at the inlet and outlet. The derived semi-analytical solution extends and addresses deficiencies of existing analytical solutions in a layered medium, which consider analogous processes such as diffusion or reaction-diffusion only and/or require the solution of complicated nonlinear transcendental equations to evaluate the solution expressions. Code implementing our semi-analytical solution is supplied and applied to a selection of test cases, with the reported results in excellent agreement with a standard numerical solution and other analytical results available in the literature.

description: Noninvasive thermometry during magnetic nanoparticle hyperthermia (MNH) remains a challenge. Our pilot study proposes a methodology to determine the noninvasive intratumoral thermal dose during MNH in the subcutaneous tumor model. Two groups of Ehrlich bearing-mice with solid and subcutaneous carcinoma, a control group (n = 6), and a MNH treated group (n = 4) were investigated. Histopathology was used to evaluate the percentage of non-viable lesions in the tumor. MNH was performed at 301 kHz and 17.5 kA.m−1, using a multifunctional nanocarrier. Surface temperature measurements were obtained using an infrared camera, where an ROI with 750 pixels was used for comparison with computer simulations. Realistic simulations of the bioheat equation were obtained by combining histopathology intratumoral lesion information and surface temperature agreement of at least 50% of the pixel’s temperature data calculated and measured at the surface. One animal of the MNH group showed tumor recurrence, while two others showed complete tumor remission (monitored for 585 days). Sensitivity analysis of the simulation parameters indicated low tumor blood perfusion. Numerical simulations indicated, for the animals with complete remission, an irreversible tissue injury of 91 ± 5% and 100%, while the one with recurrence had a lower value, 56 ± 7%. The computer simulations also revealed the in vivo heat efficiency of the nanocarrier. A new methodology for determining noninvasively the three-dimensional intratumoral thermal dose during MNH was developed. The method demonstrates the potential for predicting the long-term preclinical outcome of animals treated with MNH.

description: This paper mainly introduces the design and research of plant cultivation device in intelligent agricultural greenhouse. The device can automatically ventilate and control the temperature when the carbon dioxide content is insufficient. At the same time, the light color can be selected according to the plant properties, and the light and dark time can be controlled to provide a suitable growth environment for plants, which makes up for the shortcomings of the existing ordinary greenhouse. With China's strong support for agriculture, automatic agriculture is developing rapidly, and has a broad market prospect.

description: We study superstring theories on the Penrose limit of the enhancon geometry realized by the D(p+4)-branes wrapped on a K3 surface. We first examine the null geodesics with fixed radius in general brane backgrounds, which give solvable superstring theories with constant masses. In most cases, the superstring theories contain negative mass-squared. We clarify a condition that the world-sheet free fields have positive mass-squared. We then apply this condition to the enhancon geometry and find that the null geodesics with fixed radius exist only for p=0 case. They define the superstring theories with positive mass-squared. For p>0 case, we show that there is no null geodesic with fixed radius. We also discuss the decoupling limit which gives the dual geometry of super Yang-Mills theory with 8 supercharges. We discuss the K3-volume dependence of the superstring spectrum.

 Remarks: All populations in this study agree with the new definition given for the species by Pešić et al. (2019), based on the setation of the hind leg (IV-L-6 with long proximomedial seta). Thus, at the time being, the recently re-established H. prosiliens Koenike, 1916 (with the seta in question short) is a species restricted to Central and Northern Europe. However, as most specimens from the study area are characteristic in having also the distomedial seta of this segment long, populations from the area treated merit to be checked concerning further morphological features, and with additional methods. Hygobates paucidentis Walter, 1926, described from Morocco and considered a species incerta (Gerecke 1991), should be re-examinated as well.

description: In order to investigate the low-energy antiferromagnetic Cu-spin correlation and its relation to the superconductivity, we have performed muon spin relaxation (muSR) measurements using single crystals of the electron-doped high-Tc cuprate Pr_1-x_LaCe_x_CuO_4_ in the overdoped regime. The muSR spectra have revealed that the Cu-spin correlation is developed in the overdoped samples where the superconductivity appears. The development of the Cu-spin correlation weakens with increasing x and is negligibly small in the heavily overdoped sample where the superconductivity almost disappears. Considering that the Cu-spin correlation also exist in the superconducting electron-doped cuprates in the undoped and underdoped regimes [T. Adachi et al., J. Phys. Soc. Jpn. 85, 114716 (2016)], our findings suggest that the mechanism of the superconductivity is related to the low-energy Cu-spin correlation in the entire doping regime of the electron-doped cuprates.

description: Stroke is a medical condition in which poor blood flow to the brain results in cell death. The current treatment options are limited and only very few patients can benefit from these treatments. Stroke causes brain swelling and often a decompressive craniectomy is performed for some of the patients to release intracranial pressure to prevent further damage. As a result, a duraplasty is implanted to replace the surgically-damaged dura mater to protect the brain. In view of that, the purpose of this project was to develop double-walled microspheres (DWMS) which can be used as a drug delivery system when incorporated into duraplasty to promote endogenous stem cell therapy to treat stroke. The DWMS were composed of poly (l-lactic acid) (PLLA) and poly (lactic-co-glycolic acid) (PLGA) using a solvent evaporation method. Bovine serum albumin (BSA), as a model protein, was entrapped within these DWMS with different core-shell thicknesses and compositions to investigate the distribution of protein, encapsulation efficiency, and in vitro release. The fabrication process parameters of DWMS were also optimized to attain higher yields, and the phase separation and surface morphology were examined by differential scanning calorimetry and scanning electron microscopy.

description: We present Keck LWS images of the Orion BN/KL star forming region obtained in the first multi-wavelength study to have 0.3-0.5" resolution from 4.7 to 22 microns. The young stellar objects designated infrared source-n and radio source-I are believed to dominate the BN/KL region. We have detected extended emission from a probable accretion disk around source-n but infer a stellar luminosity on the order of only 2000 Lsun. Although source-I is believed to be more luminous, we do not detect an infrared counterpart even at the longest wavelengths. However, we resolve the closeby infrared source, IRc2, into an arc of knots ~1000 AU long at all wavelengths. Although the physical relation of source-I to IRc2 remains ambiguous, we suggest these sources mark a high density core (10^7-10^8 pc^-3 over 1000 AU) within the larger BN/KL star forming cluster. The high density may be a consequence of the core being young and heavily embedded. We suggest the energetics of the BN/KL region may be dominated by this cluster core rather than one or two individual sources.

description: A rigorous derivation and validation for linear fluid-structure-interaction (FSI) equations for a rigid-body-motion problem is performed in an Eulerian framework. We show that the added-stiffness terms arising in the formulation of Fanion et al. (2000) vanish at the FSI interface in a first-order approximation. Several numerical tests with rigid-body motion are performed to show the validity of the derived formulation by comparing the time evolution between the linear and non-linear equations when the base flow is perturbed by identical small-amplitude perturbations. In all cases both the growth rate and angular frequency of the instability matches within $0.1\%$ accuracy. The derived formulation is used to investigate the phenomenon of symmetry breaking for a rotating cylinder with an attached splitter-plate. The results show that the onset of symmetry breaking can be explained by the existence of a zero-frequency linearly unstable mode of the coupled fluid-structure-interaction system. Finally, the structural sensitivity of the least stable eigenvalue is studied for an oscillating cylinder, which is found to change significantly when the fluid and structural frequencies are close to resonance.

description: The Hubbard model on the Kagomé lattice is investigated in a metallic phase at half-filling. By introducing anisotropic electron hopping on the lattice, we control geometrical frustration and clarify how the lattice geometry affects physical properties. By means of the fluctuation exchange (FLEX) approximation, we calculate the spin and charge susceptibilities, the one-particle spectral function, the quasi-particle renormalization factor, and the Fermi velocity. It is found that geometrical frustration of the Kagomé lattice suppresses the instability to various ordered states through the strong reduction of the wavevector dependence of susceptibilities, thereby stabilizing the formation of quasi-particles due to the almost isotropic spin fluctuations in the Brillouin zone. These characteristic properties are discussed in connection with the effects of geometrical frustration in the strong coupling regime.

Using the method we investigate the possible existence of a gluon condensate of mass dimension two, , and the corresponding non-zero vacuum energy. This condensate gives rise to a dynamically generated mass for the gluon.

description: This paper reveals the origin of variation in the magnitude and temperature dependence of the normal state resistivity frequently observed in different YBCO single crystal or thin film samples with the same $T_{c}$. We investigated temperature dependence of resistivity in $YBa_{2}Cu_{3}O_{7-δ}$ thin films with 7- $δ= 6.95$ and 6.90, which were subjected to annealing in argon at 400-420 K ($120-140^{o}C$). Before annealing these films exhibited a non-linear $ρ_{ab}(T)$, with a flattening below 230 K, similar to $ρ_{b}(T)$ and $ρ_{ab}(T)$ observed in untwinned and twinned YBCO crystals, respectively. For all films the annealing causes an increase of resistivity and a transformation of $ρ_{ab}(T)$ from a non-linear dependence towards a more linear one (less flattening). In films with 7- $δ= 6.90$ the increase of resistivity is also associated with an increase in $T_{c}$. We proposed the model that provides an explanation of these phenomena in terms of thermally activated redistribution of residual O(5) oxygens in the chain-layer of YBCO. Good agreement between the experimental data for $ρ_{ab}(t,T)$, where t is the annealing time, and numerical calculations was obtained.

description: Hafnia (HfO$_2$)-based thin films have promising applications in nanoscale electronic devices due to their robust ferroelectricity and integration with silicon. However, HfO$_2$ has various stable and metastable polymorphs with quite similar structures and energies. Identifying and stabilizing the ferroelectric functional phases of HfO$_2$ have attracted intensive research interest in recent years. In this work, first-principles calculations on (111)-oriented HfO$_2$ are used to discover that imposing an in-plane shear strain on the tetragonal phase induces a nonpolar to polar phase transition. This in-plane shear-induced polar phase is shown to be an epitaxial distortion of a known metastable ferroelectric $Pnm2_1$ phase of HfO$_2$. It is proposed that this ferroelectric $Pnm2_1$ phase can account for the recently observed ferroelectricity in the (111)-oriented HfO$_2$-based thin film [Nature Materials 17, 1095-1100 (2018)]. Further investigation of this second functional ferroelectric phase in HfO$_2$ could potentially improve the performances of HfO$_2$-based films in logic and memory devices.

description: The CHAINPlan method developed by Neves (2007) is a practical tool which can be used to construct strategic plans for production chains. A preliminary step in this process includes mapping and quantifying the production chain. We present the results of applying the method to one of the most important agribusiness chains in Brazil—the cotton sector. The Gross Domestic Product for the cotton sector in the 2010-2011 crop year was estimated at nearly $19.2 billion. We show the interconnections between the links in the chain and its ability to generate revenues, taxes and jobs.

description: In this article, we consider a nabla fractional boundary value problem with general boundary conditions. Brackins \& Peterson \cite{Br} gave an explicit expression for the corresponding Green's function. Here, we show that this Green's function is nonnegative and obtain an upper bound for its maximum value. Since the expression for the Green's function is complicated, derivation of its properties may not be straightforward. For this purpose, we use a few properties of fractional nabla Taylor monomials. Using the Green's function, we will then develop a Lyapunov-type inequality for the nabla fractional boundary value problem.

description: Deutschland ist ein Einwanderungsland und Integration dementsprechend ein Thema, das an Aktualität nicht verliert. Wodurch Integration zustande kommt und was sie ausmacht, ist und bleibt jedoch unklar. Sprachkenntnisse sind ein Bestandteil der erfolgreichen Integration und stellen das wohl wichtigste Mittel der mündigen Partizipation am Staate dar. Integrationskurse bilden ein bedeutendes Instrument zur Teilhabe am Staat – nicht nur für Neuzuwander\*innen, die vornehmlich im Fokus dieser Kurse stehen, sondern auch für diejenigen Altzuwander\*innen, die, obwohl sie z. T. seit Jahren und Jahrzehnten in Deutschland leben, dennoch über nur unzureichende Sprachkenntnisse verfügen. In der vorliegenden Studie wird der Forschungsfrage nachgegangen, ob Fossilisierungen durch den Besuch eines (etwa) 9-monatigen speziell darauf ausgelegten Unterrichts aufgehalten bzw. behoben werden können. Dabei liegt der Fokus auf syntaktischen und verbalmorphologischen Strukturen innerhalb der Interlanguage von DaZ-Lerner\*innen, während andere sprachliche Phänomene sowie die Weiterentwicklung in Bereichen wie Autonomes Lernen, Medienkompetenz, Allgemeinbildung etc. davon ausgeschlossen bleiben. Forschungsgegenstand sind hierbei Kompetenz- und Performanzerscheinungen der Interlanguage von DaZ-Lerner\*innen eines Integrationskurses. Erkennbar gemacht werden diese anhand von Grammatikalitätsurteilen, Aufgabenblättern zur schriftsprachlichen Äußerung und themenzentrierten Partner\*innen- bzw. Kleingruppeninterviews. Das Ziel dieser Arbeit liegt darin, aufzuzeigen, ob Defossilisierung möglich ist.

description: This talk considers thin-walled corrugated laminates where the corrugation shape consists of circular sections.At amplitudes higher than corresponding with semi-circles, shape undercuts appear which circumstance renders mold-less manufacturing, relying on thermal curvature of unsymmetric laminates more viable than other manufacturing methods. The deformations occurring after releasing the cured laminates from the flat lamination surface, as well as the morphing behavior, imply large deformations which we address with an analytic nonlinear morphing model.
All modeling relies on periodicity of the corrugation pattern and large extension along the direction transverse to the corrugations. Periodicity defines the geometric unit cell and symmetries of geometry and internal loads within it enable a smaller mechanical unit cell. The nonlinear deformations are found by integration of curvature and strain that depend on internal loads, and these in turn on equilibrium with external morphing force. For the problem of removing discrepancy between internal forces relating to material strains and those holding equilibrium to external force, the Newton minimization method is employed because first and second derivatives of the chosen objective function are described analytically. The verified model is used to simulate morphing deformation and to study influence of laminate thickness and corrugation amplitude on line-force-stretch diagrams.

description: Adaptation to environmental fluctuations, through sensing and appropriate physiological responses, is crucial to homeostasis. Neuroepithelial cells (NECs) are putative chemoreceptors resembling mammalian Type I (glomus) cells. They have been shown to respond in vitro to changes in O2, CO2, NH3 and pH. Cytosolic carbonic anhydrase (Ca17a) is thought to be involved in CO2 sensing owing to its presence in NECs. A mutant line of zebrafish (Danio rerio) lacking functional Ca17a was generated using CRISPR/Cas9 technology and used to assess the role of Ca17a in initiating the cardiorespiratory responses to elevated CO2 (hypercapnia). Unfortunately, the homozygous knockout mutants (ca17a-/-) did not survive longer than ~12-14 days post fertilization (dpf), restricting experiments to early developmental stages (4-8 dpf). Changes in ventilation (fV) and cardiac (fH) frequency in response to hypercapnia (1% CO2) in wild type (ca17a+/+), heterozygous (ca17a+/-) and ca17a-/- fish were used to investigate Ca17a-dependent CO2 sensing and downstream signalling. Wild type fish exhibited hyperventilation during hypercapnia as indicated by an increase in fV. In the ca17a-/- fish, the hyperventilatory response was attenuated markedly, but only at 8 dpf. Hypercapnic tachycardia was observed for all genotypes and did not appear to be influenced by the absence of Ca17a. Interestingly, ca17a-/- fish exhibited a significantly reduced resting fH¬. This effect of knockout became more pronounced as the fish aged. Anesthesia did not contribute to the decreased fH in the ca17a-/- fish, nor did changes in cardiac adrenergic or cholinergic tone, which were probed using propranolol (-adrenergic receptor blocker) or atropine (muscarinic receptor blocker). The decrease in resting fH was prevented (“rescued”) when ca17a-/- embryos were injected with ca17a mRNA. Collectively, the results of this thesis support a role for Ca17a in promoting hyperventilation during hypercapnia in larval zebrafish and suggest a previously unrecognized role for Ca17a in determining resting heart rate.

 Remarks: The status of a separate species has been recognized by Martin & Davids (2004) for populations of H. setosus Besseling, 1942, a taxon over a long time considered a junior synonym of H. nigromaculatus - for details see also Martin et al. (2010). Recently, Pešić et al. (2020) published two further related species from the Balkans, showing that H. nigromaculatus represents a more diversified species group. Obviously, also many Italian records given above require re-investigation. However, in view of the characteristics of their collecting sites, at least for the specimens from the large prealpine lakes it is probable that they represent in fact H. nigromaculatus sensu stricto.
Habitat: Lenitobiont. Large streams, littoral of lakes.
 Distribution: Palaearctic? In view of the new data concerning H. nigromaculatus -like mites, all distribution data from the 20 th century are questionable.
