description: The reaction of electrons stored on TiO2 nanoparticles with heavy metal ions Hg (II), Ni (II) and Pb (II) has been studied employing steady state and stopped flow spectrophotometric techniques. Prior to kinetic investigation the formation of metal deposits is detected by their surface Plasmon absorbance observed after mixing of their corresponding metal ions with stored electron on TiO2 nanoparticles (eTiO2-). The dynamic of transfer of stored TiO2 electrons to Hg (II), Pb (II) and Ni (II) in water has been investigated after mixing in the stopped flow chamber following the decrease of the absorbance of eTiO2- at 600nm. The results indicate that Hg (II), Pb (II) and Ni (II) ions react readily with eTiO2-The kinetic parameters of the electron transfer reactions have been obtained by pseudo first order fitting. In the presence of Hg (II) ions, the transients decay followed by a buildup at 380-480nmrange. In the presence of Pb (II) and Ni (II), a concurrent decay of TiO2 electron absorbance and buildup of the absorbance of metal deposits were observed. The rate constants of the electron transfer reactions induced by TiO2 stored electrons to metal ions increase with the driving force of the reaction according to Tafel equation.

description: This study describes the purification of penicillin G amidase (PGA) by ion exchange membrane adsorbers in a one-step-process. Preliminary experiments with high-throughput screening devices in microliter scale (8-strip modules) were performed to find suitable purification strategy and appropriate ion exchange ligands as well as basic process conditions for binding and elution. Best purification results were achieved by strong cation-exchange (S-) membrane adsorbers loaded with 2ml/min enzyme solution at pH 6.0 and eluted at pH 6.0 with 0.05M NaCl, which led to a high yield of bound PGA (98%) without any visible remains of host cell proteins and with a residual enzyme activity of 80-85%. The binding of PGA to the S-membrane was further investigated in an upscaling to milliliter scale with LP15 modules and breakthrough curves were determined by varying the flow rates: the PGA-binding to S-membrane adsorbers is independent of the flow rate. Dynamic binding capacities were estimated to be 0.69mg PGA/cm2 (25.5mg/ml) for 10% breakthrough respectively 0.95mg/cm2 (35.2mg/ml) for 100% breakthrough. Finally, real cell lysate samples from Escherichia coli culture containing PGA were processed under the found optimal conditions. Despite exceeded loading PGA was isolated from this complex mixture successfully fourfold concentrated and with a purification factor of 101.3 and a resulting specific activity of 4.97U/mg.

description: We study the solutions of the Rosenberg--Markoff equation ax^2+by^2+cz^2 = dxyz (a generalization of the well--known Markoff equation). We specifically focus on looking for solutions in arithmetic progression that lie in the ring of integers of a number field. With the help of previous work by Alvanos and Poulakis, we give a complete decision algorithm, which allows us to prove finiteness results concerning these particular solutions. Finally, some extensive computations are presented regarding two particular cases: the generalized Markoff equation x^2+y^2+z^2 = dxyz over quadratic fields and the classic Markoff equation x^2+y^2+z^2 = 3xyz over an arbitrary number field.

description: Flavonoids are low-molecular-weight phenolic compounds that are widely distributed in the plant kingdom. They have different roles in plant resistance to biotic and abiotic stresses. The transcription factor gene MdMyb10 (Gene Bank: DQ267896) was introduced into two apple (Malus domestica Borkh.) cultivars i.e. ‘Holsteiner Cox (HC)’ and ‘Gala’ via Agrobacterium-mediated transformation. The regenerated shoots were selected on kanamycin containing media. The presence of additional MdMyb10 gene in putative shoots was confirmed by PCR, RT-PCR and Southern blotting. Expression level of introduced MdMyb10 gene was analyzed by quantitative real time PCR. The results confirmed a dramatic increase in overexpression of MdMyb10 in the transgenic plants, up to 1261 and 847-folds for cultivars Holsteiner Cox and Gala, respectively compared to non-transformed negative control plants. HPLC-MS was used to determine the levels of different flavonoid compounds in both non-transgenic and transgenic plants. In MdMyb10 ‘HC’ transgenic plants, some of the polyphenols analyzed were enhanced while others were reduced in comparison to their levels in the non-transgenic plants. On the other hand, all of the analyzed polyphenol classes were induced in MdMyb10 ‘Gala’ transgenic plants in comparison to their levels in the non-transgenic plants. In the present study, the flavonoid pathway was successfully modified in apple by overexpressing the MdMyb10 transcription factor to validate the hypothesis of increased effect on plant disease resistance.

description: We demonstrate that fluid flow cloaking solutions based on active hydrodynamic metamaterials exist for two-dimensional flows past a cylinder in a wide range of Reynolds numbers, up to approximately 200. Within the framework of the classical Brinkman equation for homogenized porous flow, we demonstrate using two different methods that such cloaked flows can be dynamically stable for $Re$ in the range 5-119. The first, highly efficient, method is based on a linearization of the Brinkman-Navier-Stokes equation and finding the eigenfrequencies of the least stable eigen-perturbations; the second method is a direct, numerical integration in the time domain. We show that, by suppressing the Karman vortex street in the weekly turbulent wake, porous flow cloaks can raise the critical Reynolds number up to about 120, or five times greater than for a bare, uncloaked cylinder.

description: We consider a dense one-dimensional laser-driven Rydberg lattice gas with perfect nearest-neighbor blockade. The ground state of this system can be found analytically in certain parameter regimes even when the applied fields are inhomogeneous in space. We will use this unique feature to investigate the effect of an impurity - introduced by the local variation of the laser parameters - on the correlations of the many-body ground state. Moreover, we explore the role of a staggered laser field which alternates from site to site thereby breaking the sublattice symmetry. We demonstrate that this technique, which can be applied experimentally, reveals insights into the role of long-range interactions on the critical properties of a Rydberg gas. Our work highlight novel possibilities for the exploration of many-body physics in Rydberg lattice gases based on locally tuneable laser fields.

Publisher: name: Old Dominion University Libraries
Year: 2019

description: Limited research has investigated dissertation methodology choice and the factors that contribute to this choice. Quantitative research is based in mathematics and scientific positivism, and qualitative research is based in constructivism. These underlying philosophical differences posit the question if certain factors predict dissertation methodology choice. Using the theoretical framework of intersectionality, this predictive, correlational study used archival data to determine if biological sex, ethnicity, age, or religious affiliation predicts dissertation methodology choice. A logistics regression analysis was used to review 398 doctoral dissertations and determine if any of the criterion variables predicted dissertation methodology choice. After analysis, it was determined that none of the criterion variables of biological sex, ethnicity, age, and religious affiliation were statistically significant in predicting dissertation methodology choice.

description: Recent years mesh-based Peer-to-Peer live streaming has become a promising way for service providers to offer high-quality live video streaming service to Internet users. In this paper, we make a detailed study on modeling and performance analysis of the pull-based P2P streaming systems. We establish the analytical framework for the pull-based streaming schemes in P2P network, give accurate models of the chunk selection and peer selection strategies, and organize them into three categories, i.e., the chunk first scheme, the peer first scheme and the epidemic scheme. Through numerical performance evaluation, the impacts of some important parameters, such as size of neighbor set, reply number, buffer size and so on are investigated. For the peer first and chunk first scheme, we show that the pull-based schemes do not perform as well as the push-based schemes when peers are limited to reply only one request in each time slot. When the reply number increases, the pull-based streaming schemes will reach close to optimal playout probability. As to the pull-based epidemic scheme, we find it has unexpected poor performance, which is significantly different from the push-based epidemic scheme. Therefore we propose a simple, efficient and easily deployed push-pull scheme which can significantly improve the playout probability.

description: We have searched for and estimated the possible gravitational influence of dark matter in the Solar system based on the EPM2011 planetary ephemerides using about 677 thousand positional observations of planets and spacecraft. Most of the observations belong to present-day ranging measurements. Our estimates of the dark matter density and mass at various distances from the Sun are generally overridden by their errors ($σ$). This suggests that the density of dark matter $ρ_{dm}$, if present, is very low and is much less than the currently achieved error of these parameters. We have found that $ρ_{dm}$ is less than $1.1\cdot10^{-20}$ g cm$^{-3}$ at the orbital distance of Saturn, $ρ_{dm}<1.4\cdot10^{-20}$ g cm$^{-3}$ at the orbital distance of Mars, and $ρ_{dm}<1.4\cdot10^{-19}$ g cm$^{-3}$ at the orbital distance of the Earth. We also have considered the case of a possible concentration of dark matter to the Solar system center. The dark matter mass in the sphere within Saturn's orbit should be less than $1.7\cdot10^{-10} M_{\odot}$ even if its possible concentration is taken into account.

description: The geometric aspects of quantum mechanics are underlined most prominently by the concept of geometric phases, which are acquired whenever a quantum system evolves along a closed path in Hilbert space. The geometric phase is determined only by the shape of this path and is -- in its simplest form -- a real number. However, if the system contains degenerate energy levels, matrix-valued geometric phases, termed non-abelian holonomies, can emerge. They play an important role for the creation of synthetic gauge fields in cold atomic gases and the description of non-abelian anyon statistics. Moreover, it has been proposed to exploit non-abelian holonomic gates for robust quantum computation. In contrast to abelian geometric phases, non-abelian ones have been observed only in nuclear quadrupole resonance experiments with a large number of spins and without fully characterizing the geometric process and its non-commutative nature. Here, we realize non-abelian holonomic quantum operations on a single superconducting artificial three-level atom by applying a well controlled two-tone microwave drive. Using quantum process tomography, we determine fidelities of the resulting non-commuting gates exceeding 95 %. We show that a sequence of two paths in Hilbert space traversed in different order yields inequivalent transformations, which is an evidence for the non-abelian character of the implemented holonomic quantum gates. In combination with two-qubit operations, they form a universal set of gates for holonomic quantum computation.

description: The properties of the entanglement entropy (EE) of two particle excited states in a one-dimensional ring are studied. For a clean system we show analytically that as long as the momenta of the two particles are not close, the EE is twice the value of the EE of any single particle state. For almost identical momenta the EE is lower than this value. The introduction of disorder is numerically shown to lead to a decrease in the median EE of a two particle excited state, while interactions (which have no effect for the clean case) mitigate the decrease. For a ring which is of the same size as the localization length, interaction increase the EE of a typical two particle excited state above the clean system EE value.

description: Since the mechanism governing the partitioning behavior of biomolecules, such as proteins and enzymes, in polyethylene glycol (PEG)-salt aqueous two-phase systems (ATPS) is complex and not easily predictable, many laborious experiments have to be performed for an optimization of these systems, causing increased overall cost. However, the multivariate statistical design of experiments (DoE) methodology is representing a promising and efficient optimization technique which can overcome the limitations of traditional optimization methods. Therefore, DoE has emerged as a powerful and efficient optimization tool for PEG-salt ATPS, since it is faster, more efficient and cost-effective, allowing a simultaneous and rigorous evaluation of process/system parameters. In the present review, different DoE process steps are represented to highlight the feasibility of this approach to operate as a promising and efficient optimization tool, thus facilitating the evaluation of the partitioning behavior, recovery and purification of different proteins and enzymes in PEG-salt ATPS. In this context, several experimental designs, such as factorial and response surface designs, have been discussed and evaluated by statistical regression analysis and analysis of variance (ANOVA), as well as various applications of PEG-salt ATPS using DoE have been outlined which may further promote the optimization of these systems.

description: Recent efforts to increase Ascochyta blight resistance of pea have focused on the introduction of foreign genes by genetic engineering. The rpgip1 gene from Rubus idaeus was introduced by Agrobacterium-mediated transformation into Pisum sativum, cv. Baroness with the aim to increase pea resistance to fungal diseases. Notwithstanding this success, practical applications have to be preceded by the development of analytical methods for screening. Singleplex and multiplex PCR assays were employed to test primer efficiency in identifying the rpgip1 transgene in 11 pea genotypes. Five from ten primer combinations were effective in identifying transgene or insert sequences. PCR amplification using five other primer pairs revealed unspecific amplicons. According to in silico analyses, they arose from retrotransposons and pea genes including homologues of rpgip1. Two sets of primers were prepared with the aim of simultaneous amplification of different rpgip1 fragments. Fingerprints were sums of bands observed from individual pairs so the utility of multiplex assays was demonstrated. An additional advantage of multiplex PCR was clear differentiation between the transgene and endogenous pgip genes present in the donor species, R. idaeus. Sequencing of two PCR products confirms that no substantial rearrangements at the rpgip1 transgene arose during development of transgenic plants. However, a deletion occurred at 59 bp in the PGIP+VST line and a substitution at 392 bp in the PGIP line. The frequency of point mutations was not high (1.1 × 10-3) and comparable with the frequency expected for host genes based on the neutral theory of molecular evolution.
title: Nest modifications by the acorn ant Temnothorax crassispinus (Hymenoptera: Formicidae)
Creators: name: Mitrus, Slawomir

description: Many ant species construct nests and during the process considerably influence the environment such as by changing soil structure and creating new habitat for other species. However, other ant species dwell in ready-for-use cavities. Ants of the genus Temnothorax inhabit small cavities such as acorns and under rocks, but under natural conditions, good nest sites are limited resources. During field and laboratory experiments, I studied how the acorn ant Temnothorax crassispinus (Karawajew, 1926) modifies nesting sites. Temnothorax crassispinus is a forest species, which typically lives in cavities in fallen twigs and acorns; colonies usually number from a few dozen to about 200 workers. Although it is known that they prefer narrow entrances, in a field experiment, a similar proportion of artificial nest sites with narrower and wider entrances were inhabited, and most colonies decreased entrance sizes. Similarly, in laboratory experiments, colonies decreased entrance sizes. Colonies used more sand grains when sand was placed closer to the nest entrance than when it was farther; however, I found no relationship between the number of grains of sand used for such modifications and colony size, and the presence of other colonies in the same Petri dishes did not affect entrance-size reduction. Other experiments showed that the ants can enlarge the nest cavity, but this depends on the material filling the cavity, and that the ants are able to dig nest chambers just in soil. Thus, acorn ants can modify and create nest sites, and may thus also modify the environment.
Unpacking IPCC and IPBES Reports

description: This repo hosts the slides for our presentation Unpacking IPCC and IPBES Reports at TDWG 2022. The video is also available via https://youtu.be/TtapQuP64XU. Abstract Humanity is facing a set of existential challenges, including the handling of the parallel and interconnected crises of climate change and biodiversity loss. In an effort to address these challenges, international bodies like the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) have been created. These bodies are producing a series of reports that compile scientific information on specific aspects of climate and biodiversity research and discuss policy options and other social implications. So far, these reports have been provided in formats that make it hard to mobilize the knowledge encapsulated in them. Our contribution demonstrates technical workflows for achieving such mobilization by mining the reports. Development of these workflows is spearheaded by young researchers from the SemanticClimate team of interns based at the National Institute of Plant Genome Research (NIPGR) in New Delhi, India, and volunteers from all over the world. The tool chain includes methods for cleaning up the formatting, for extracting and processing raw text, tables and figures and annotating them semantically with the help of controlled vocabularies, ontologies and Wikidata. The semantic information and the mined information can then be combined in a way that iteratively improves both, eventually resulting in versions of the reports wherein entities like species, countries or references are semantically marked up and rendered in responsive formats. Our framework supports multilingual and specialist interests (e.g., endangered species, plant chemistry), and we will also briefly discuss how the use of standard open licensing could further contribute to mobilizing information from the reports. We are keen to work with other groups sharing these interests as well as with the teams involved in producing the reports.

description: We argue that compactifications on Calabi-Yau threefolds with vanishing Euler number yield effective four dimensional theories exhibiting (spontaneously broken) N=4 supersymmetry. To this end, we derive the low-energy effective action for general SU(2) structure manifolds in type IIA string theory and show its consistency with gauged N=4 supergravity. Focusing on the special case of Calabi-Yau manifolds with vanishing Euler number, we explain the absence of perturbative corrections at the two-derivative level. In addition, we conjecture that all non-perturbative corrections are governed and constrained by the couplings of N=4 massive gravitino multiplets.

description: Nonclassicality and entanglement are notions fundamental to quantum information processes involving continuous variable systems. That these two notions are intimately related has been intuitively appreciated for quite some time. An aspect of considerable interest is the behaviour of these attributes of a state under the action of a noisy channel. Inspired by the notion of entanglement-breaking channels, we define the concept of nonclassicality-breaking channels in a natural manner. We show that the notion of nonclassicality-breaking is essentially equivalent---in a clearly defined sense of the phrase `essentially'---to the notion of entanglement-breaking, as far as bosonic Gaussian channels are concerned. This is notwithstanding the fact that the very notion of entanglement-breaking requires reference to a bipartite system, whereas the definition of nonclassicality-breaking makes no such reference. Our analysis rests on our classification of channels into nonclassicality-based, as against entanglement-based, types of canonical forms. Our result takes ones intuitive understanding of the close relationship between nonclassicality and entanglement a step closer.

description: Phenolic (PAs) and amino acids (AAs) contribute potentially to the stabilization of organic matter (OM) in soil by forming mineral–organic associations (MOAs). However, little is known about how natural OM coating affects the adsorption of these compounds and their mutual interaction upon adsorption. Therefore, batch adsorption experiments were carried out to study how coatings of minerals with dissolved organic matter (DOM) obtained from forest leaf litter (L-DOM) and from the O horizon (O-DOM) affect the adsorption of phenolic acids (salicylic, syringic, ferulic and vanillic acid) and amino acids (lysine, glutamic acid, leucine and phenylalanine) at pH 6. Moreover, the adsorption of PAs on OM-coated minerals was tested after preconditioning by AAs and vice versa. Adsorption of DOM depended on the mineral (goethite ≫ kaolinite > montmorillonite) and sources of DOM (O-DOM > L-DOM for goethite). Coatings of all minerals with both DOM sources reduced the adsorption of PAs and the acidic glutamic acid but enhanced that of the basic lysine. The adsorption of PAs decreased with increasing OM coating of the minerals. Strong bonds between AAs and OM-coated minerals generally enhanced adsorption of PAs with preconditioning by AAs. This indirectly indicates a multilayer model of MOA. Adsorption of AAs, however, was rarely influenced by preconditioning with PAs. Competition between AAs and PAs generally suppressed the adsorption of AAs on coated minerals, whereas the PAs were hardly affected. These results emphasize that the amount and composition of OM coating must be considered when studying the adsorption of PAs and AAs in soil. Highlights: Adsorption of DOM on minerals followed the order: goethite ≫ kaolinite > montmorillonite. Adsorption of O-DOM (O horizon) on goethite was larger than that of L-DOM (leaf litter). Coatings of DOM reduced adsorption of PAs and acidic AAs and enhanced that of basic AAs. The amount and composition of OM coating affected the adsorption of PAs and AAs.

description: In this paper we use the GeneralizedMultiscale Finite ElementMethod (GMsFEM) framework, introduced in [20], in order to solve nonlinear elliptic equations with high-contrast coefficients. The proposed solution method involves linearizing the equation so that coarse-grid quantities of previous solution iterates can be regarded as auxiliary parameters within the problem formulation. With this convention, we systematically construct respective coarse solution spaces that lend themselves to either continuous Galerkin (CG) or discontinuous Galerkin (DG) global formulations. Here, we use Symmetric Interior Penalty Discontinuous Galerkin approach. Both methods yield a predictable error decline that depends on the respective coarse space dimension, and we illustrate the effectiveness of the CG and DG formulations by offering a variety of numerical examples.

On the Distribution of MIMO Mutual Information: An In-Depth Painlevé Based Characterization

description: This paper builds upon our recent work which computed the moment generating function of the MIMO mutual information exactly in terms of a Painlevé V differential equation. By exploiting this key analytical tool, we provide an in-depth characterization of the mutual information distribution for sufficiently large (but finite) antenna numbers. In particular, we derive systematic closed-form expansions for the high order cumulants. These results yield considerable new insight, such as providing a technical explanation as to why the well known Gaussian approximation is quite robust to large SNR for the case of unequal antenna arrays, whilst it deviates strongly for equal antenna arrays. In addition, by drawing upon our high order cumulant expansions, we employ the Edgeworth expansion technique to propose a refined Gaussian approximation which is shown to give a very accurate closed-form characterization of the mutual information distribution, both around the mean and for moderate deviations into the tails (where the Gaussian approximation fails remarkably). For stronger deviations where the Edgeworth expansion becomes unwieldy, we employ the saddle point method and asymptotic integration tools to establish new analytical characterizations which are shown to be very simple and accurate. Based on these results we also recover key well established properties of the tail distribution, including the diversity-multiplexing-tradeoff.

description: Plant-unique membrane receptor kinases with leucine-rich repeat ectodomains (LRR-RKs) can sense small molecule, peptide, and protein ligands. Many LRR-RKs require SERK-family coreceptor kinases for high-affinity ligand binding and receptor activation. How one coreceptor can contribute to the specific binding of distinct ligands and activation of different LRR-RKs is poorly understood. Here we quantitatively analyze the contribution of SERK3 to ligand binding and activation of the brassinosteroid receptor BRI1 and the peptide hormone receptor HAESA. We show that while the isolated receptors sense their respective ligands with drastically different binding affinities, the SERK3 ectodomain binds the ligand-associated receptors with very similar binding kinetics. We identify residues in the SERK3 N-terminal capping domain, which allow for selective steroid and peptide hormone recognition. In contrast, residues in the SERK3 LRR core form a second, constitutive receptor-coreceptor interface. Genetic analyses of protein chimera between BRI1 and SERK3 define that signaling-competent complexes are formed by receptor-coreceptor heteromerization in planta. A functional BRI1-HAESA chimera suggests that the receptor activation mechanism is conserved among different LRR-RKs, and that their signaling specificity is encoded in the kinase domain of the receptor. Our work pinpoints the relative contributions of receptor, ligand, and coreceptor to the formation and activation of SERK-dependent LRR-RK signaling complexes regulating plant growth and development. © 2018 National Academy of Sciences.

description: Silicon is now firmly established as a high performance photonic material. Its only weakness is the lack of a native electrically driven light emitter that operates CW at room temperature, exhibits a narrow linewidth in the technologically important 1300- 1600 nm wavelength window, is small and operates with low power consumption. Here, an electrically pumped all-silicon nano light source around 1300-1600 nm range is demonstrated at room temperature. Using hydrogen plasma treatment, nano-scale optically active defects are introduced into silicon, which then feed the photonic crystal nanocavity to enahnce the electrically driven emission in a device via Purcell effect. A narrow (Δλ = 0.5 nm) emission line at 1515 nm wavelength with a power density of 0.4 mW/cm2 is observed, which represents the highest spectral power density ever reported from any silicon emitter. A number of possible improvements are also discussed, that make this scheme a very promising light source for optical interconnects and other important silicon photonics applications.

description: A DG algebras $A$ over a field $k$ with $H(A)$ connected and $H_{<0}(A)=0$ has a unique up to isomorphism DG module $K$ with $H(K)\cong k$. It is proved that if $H(A)$ is degreewise finite, then $RHom_A(?,K): D^{df}_{+}(A)^{op} \equiv D_{df}^{+}}(RHom_A(K,K))$ is an exact equivalence of derived categories of DG modules with degreewise finite-dimensional homology. It induces an equivalences of $D^{df}_{b}(A)^{op}$ and the category of perfect DG $RHom_A(K,K)$-modules, and vice-versa. Corresponding statements are proved also when $H(A)$ is simply connected and $H^{<0}(A)=0$.

description: We have studied three most recent precursor flares in the light curve of the blazar OJ 287 while invoking the presence of a precessing binary black hole in the system to explain the nature of these flares. Precursor flare timings from the historical light curves are compared with theoretical predictions from our model that incorporate effects of an accretion disk and post-Newtonian description for the binary black hole orbit. We find that the precursor flares coincide with the secondary black hole descending towards the accretion disk of the primary black hole from the observed side, with a mean z-component of approximately z_c = 4000 AU. We use this model of precursor flares to predict that precursor flare of similar nature should happen around 2020.96 before the next major outburst in 2022.
