Response of Riesling clones to mechanical hedging and minimal pruning of cordon trained vines (MPCT) implications for clonal selection
Creators: name: Clingeleffer, P. R.
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: Three pruning treatments were superimposed on an established Riesling clonal selection trial situated in a hot irrigated Australian vineyard. Significant yield differences over 4 seasons between conventional spur pruning (mean 12.8 kg/vine) and the light pruning treatments, hedging and MPCT (means 14.2 and 13 .8 kg respectively), were found. Light pruning treatments produced smaller berries, but effects on soluble solids, pH and titratable acidity were small. Yield differences between the four clones, two Australian selections SA173 and SA140 and imported clones from Europe and California, were significant in the combined analyses of the three pruning treatments. SA173 (mean 14.7 kg/vine) h ad superior production while production by SA140 (12.7 kg) was inferior. The two imported clones gave similar yields. Clonal differences were not significant with spur pruning in any season but significant differences with the light pruning treatments were evident in 3 out of 4 seasons and over the 4 years. This-suggests that traditional severe pruning used in clonal selection trials may limit the production of improved clones.

description: Grapevines growing on two low P soils were shown to have petiole TP levels below currently accepted critical levels established for the Thompson Seedless variety. Soil application of different P fertilizers increased lamina EP and pruning weights in the season immediately following application. In the 2nd season after application, duster numbers and yields of P-treated Chardonnay and Chenin blanc grapevines were greater than for the untreated controls. Different sources of P, applied at various rates either during the growing or dormant seasons, were effective in alleviating P deficiency. However, the largest and most sustaineq increases in P status were associated with the largest P application rates. Therefore, under certain low P soil conditions repeated small applications of P every 2-3 years may be necessary to maintain adequate vine P status. Preliminary critical P levels of 0.8 g lamina EP/kg dw for Chardonnay (own roots) and 1.5 g lamina EP/kg dw for Chenin blanc (St. George rootstock) were established based on yield responses.

description: Ten samples of solid sodium dithionite (Na2S2O4) at various stages of decomposition were analyzed using iodometric titration, ion chromatography, and Raman spectroscopy. As the sample age increased, there was a decrease in the measured dithionite and sodium compositions with a subsequent increase in the decomposition products of sulfite, thiosulfate, and sulfate. Significant decrease in purity occurs over first month for samples used as laboratory chemical regents. This decomposition is likely a result of the adsorption and reaction of water when the sample was exposed to atmosphere as well as redox reactions with oxygen and between sulphur oxyanions. For the oldest solid sample, Raman peaks characteristic of sulfate and tetrathionate were also present, signifying additional decomposition pathways had occurred. The existence of significant quantities of species in the solids samples that are the result of dithionite coupling, for example tetrathionate, have not been observed as decomposition products in aqueous solutions and their presence affects the established iodometric titration results for quantification of sodium dithionite.

description: The angular correlation of the electrons in the neutrinoless double beta decay ($0\nu2β$) is calculated taking into account the nucleon recoil, the $S$ and $P$-waves for the electrons and the electron mass using a general Lorentz invariant effective Lagrangian. We show that the angular coefficient is essentially independent of the nuclear matrix element models. We work out the angular coefficient in several scenarios for new physics, in particular, in the left-right symmetric models.

description: We provide an efficient method for computing the maximum likelihood mixed quantum state (with density matrix $ρ$) given a set of measurement outcome in a complete orthonormal operator basis subject to Gaussian noise. Our method works by first changing basis yielding a candidate density matrix $μ$ which may have nonphysical (negative) eigenvalues, and then finding the nearest physical state under the 2-norm. Our algorithm takes at worst $O(d^4)$ for the basis change plus $O(d^3)$ for finding $ρ$ where $d$ is the dimension of the quantum state. In the special case where the measurement basis is strings of Pauli operators, the basis change takes only $O(d^3)$ as well. The workhorse of the algorithm is a new linear-time method for finding the closest probability distribution (in Euclidean distance) to a set of real numbers summing to one.

description: We address a natural question in noncommutative geometry, namely the rigidity observed in many examples, whereby noncommutative spaces (or equivalently their coordinate algebras) have very few automorphisms by comparison with their commutative counterparts. In the framework of noncommutative projective geometry, we define a groupoid whose objects are noncommutative projective spaces of a given dimension and whose morphisms correspond to isomorphisms of these. This groupoid is then a natural generalization of an automorphism group. Using work of Zhang, we may translate this structure to the algebraic side, wherein we consider homogeneous coordinate algebras of noncommutative projective spaces. The morphisms in our groupoid precisely correspond to the existence of a Zhang twist relating the two coordinate algebras. We analyse this automorphism groupoid, showing that in dimension 1 it is connected, so that every noncommutative $\mathbb{P}^{1}$ is isomorphic to commutative $\mathbb{P}^{1}$. For dimension 2 and above, we use the geometry of the point scheme, as introduced by Artin-Tate-Van den Bergh, to relate morphisms in our groupoid to certain automorphisms of the point scheme. We apply our results to two important examples, quantum projective spaces and Sklyanin algebras. In both cases, we are able to use the geometry of the point schemes to fully describe the corresponding component of the automorphism groupoid. This provides a concrete description of the collection of Zhang twists of these algebras.

description: A lattice model for strongly interacting electrons motivated by a rank-3 tensor model provides a tool for understanding the pairing mechanism of high-temperature superconductivity. This SYK-like model describes the strange metal phase in the cuprate high temperature superconductors. Our calculation indicates that the superconducting gap ratio in this model is higher than the ratio in the BCS theory due to the coupling term and the spin operator. Under certain conditions, the ratio also agrees with the BCS theory. Our results relate to the case of strong coupling, so it may pave the way to gaining insight into the cuprate high temperature superconductors.

The development of the cuticle and epicuticular wax of the grape berry
Creators: name: Rosenquist, Janet K.

Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: The cuticle and epicuticular wax of Thompson Seedless grape berries developed as morphologically and developmentally distinct layers covering the epidermal cells of the pistil. The ovary surface had no cuticle or wax covering until approximately 4 weeks before anthesis. The cuticle began to form about 3 weeks before anthesis as highly organized, tightly appressed cuticular ridges. These ridges began to spread apart late in the period of pre-anthesis pistil expansion. The ridges continued to spread apart and flatten, and became progressively more disorganized during post-anthesis berry growth. Epicuticular wax formation began with the appearance of small, simple wax platelets within a few days after anthesis. The wax platelets increased in size, number and cornplexity. as the berries matured.

description: Ranking algorithms play a crucial role in online platforms ranging from search engines to recommender systems. In this paper, we identify a surprising consequence of popularity-based rankings: the fewer the items reporting a given signal, the higher the share of the overall traffic they collectively attract. This few-get-richer effect emerges in settings where there are few distinct classes of items (e.g., left-leaning news sources versus right-leaning news sources), and items are ranked based on their popularity. We demonstrate analytically that the few-get-richer effect emerges when people tend to click on top-ranked items and have heterogeneous preferences for the classes of items. Using simulations, we analyze how the strength of the effect changes with assumptions about the setting and human behavior. We also test our predictions experimentally in an online experiment with human participants. Our findings have important implications to understand the spread of misinformation.

Further, we show that if we perturb a graph $G$ in a certain way, then the independence complex of this new graph is homotopy equivalent to the suspension of the independence complex of $G$.

description: The contents of total and individual anthocyanins in red leaves of three Vitis vinifera L. cvs (Merlot noir, Cabernet Sauvignon and Gamay Freaux) was determined by HPLC at three stages of seasonal development (veraison and maturity of grapes, leaf fall). The anthocyanin composition of leaves and berries was rather different. There was some variation between cultivars: leaves of the red-juice grape were richer in anthocyanins than leaves of the non-colouring cultivars. In all cultivars, the anthocyanin content of leaves increased during grapeberry maturation, then decreased until leaf fall.

description: The multiscale entanglement renormalization ansatz describes quantum many-body states by a hierarchical entanglement structure organized by length scale. Numerically, it has been demonstrated to capture critical lattice models and the data of the corresponding conformal field theories with high accuracy. However, a rigorous understanding of its success and precise relation to the continuum is still lacking. To address this challenge, we provide an explicit construction of entanglement-renormalization quantum circuits that rigorously approximate correlation functions of the massless Dirac conformal field theory. We directly target the continuum theory: discreteness is introduced by our choice of how to probe the system, not by any underlying short-distance lattice regulator. To achieve this, we use multiresolution analysis from wavelet theory to obtain an approximation scheme and to implement entanglement renormalization in a natural way. This could be a starting point for constructing quantum circuit approximations for more general conformal field theories.

description: Conventional reinforcement learning (RL) typically determines an appropriate primitive action at each timestep. However, by using a proper macro action, defined as a sequence of primitive actions, an agent is able to bypass intermediate states to a farther state and facilitate its learning procedure. The problem we would like to investigate is what associated beneficial properties that macro actions may possess. In this paper, we unveil the properties of reusability and transferability of macro actions. The first property, reusability, means that a macro action generated along with one RL method can be reused by another RL method for training, while the second one, transferability, means that a macro action can be utilized for training agents in similar environments with different reward settings. In our experiments, we first generate macro actions along with RL methods. We then provide a set of analyses to reveal the properties of reusability and transferability of the generated macro actions.

description: We consider three monads on Top, the category of topological spaces, which formalize topological aspects of probability and possibility in categorical terms. The first one is the Hoare hyperspace monad H, which assigns to every space its space of closed subsets equipped with the lower Vietoris topology. The second is the monad V of continuous valuations, also known as the extended probabilistic powerdomain. We construct both monads in a unified way in terms of double dualization. This reveals a close analogy between them, and allows us to prove that the operation of taking the support of a continuous valuation is a morphism of monads from V to H. In particular, this implies that every H-algebra (topological complete semilattice) is also a V-algebra. Third, we show that V can be restricted to a submonad of tau-smooth probability measures on Top. By composing these two morphisms of monads, we obtain that taking the support of a tau-smooth probability measure is also a morphism of monads.

description: The antioxidant properties and the foliar phenol composition of 25 Mexican varieties of Phaseolus vulgaris L. (common bean) were evaluated. Phaseolus coccineus was analysed with comparative aims. The high performance liquid chromatography with photodiode array detection analysis revealed 27 phenolics in the leaves of P. vulgaris (13 quercetin-3-O-glycosides, 8 kaempferol-3-O-glycosides, 2 myricetin glycosides and 4 phenolic acids) and 5 in P. coccineus (2 kaempferol-3-O-glycoside, 2 apigenin-7-O-glycoside and 1 luteolin-7-O-glycoside). All extracts showed high levels of phenols and flavonoids (0.964–5.601 mg g− 1 dry tissue, and 0.287–1.418 mg g− 1 dry tissue, respectively) and relevant antioxidant properties, suggesting that the leaves of the varieties of P. vulgaris are a significant source of natural antioxidants. The foliar phenol profiles were species-specific and, besides, the qualitative variation allowed discriminating among varieties of P. vulgaris. These profiles can represent an important varietal authenticity proof.

description: The objective of this study was to determine total phenolic and flavonoid contents, antioxidant and antimicrobial activities of methanolic extracts from the leaves and barks of three Alnus species. The phenolic and flavonoid contents of extracts were determined spectrophotometrically using Folin–Ciocalteau and aluminium chloride methods, respectively. In addition, antioxidant activity of the extracts was determined using 1,1-diphenyl-2-picrylhydrazyl radical scavenging method. The antimicrobial activity was performed by disc diffusion assay against six reference bacterial strains including Gram-negative and Gram-positive bacteria and two fungal strains. Extract of Alnus viridis bark contained the highest amounts of total phenolics (780 mg CAT/g), while extract of A. viridis leaves had the highest amount of flavonoids (30.01 mg RUT/g). All extracts showed antioxidant activity higher than thymol, which was used as a positive probe. The largest diameters of inhibition zone (25 mm) were recorded with Bacillus subtilis 168 M and Staphylococcus aureus ATCC 6538.

description: The Sustainable Archives and Leveraging Technologies group (SALT) at UNC is pursuing a number of projects that address issues of interoperability and reproducibility. This presentation will discuss 3 projects: (1) e-Legacy, an NHPRC-funded project which is developing preservation infrastructure and services for state government geospatial data, (2) PoDRI, an IMLS-funded project which explores policy-based interoperability between Fedora and iRODS repositories, and (3) T-RACES (Testbed for the Redlining Archives of California's Exclusionary Spaces), an IMLS-funded project which builds on these other projects and will publish an online archive of historical redlining and racial discrimination data. T-RACES documents the New Deal Home Owners' Loan Corporation federal agency's confidential security maps and surveys of the 1930s. These surveys form the genesis of neighborhood discrimination and restricted mortgage lending, known as redlining. A digital library interface based on interactive databases and Google Map and Google Earth interfaces will integrate data from 8 California cities, including Los Angeles, San Francisco, and Oakland. The intent of this archive is to serve as a core reference data set that can be augmented and customized through social networking mechanisms, through overlays of social science data. Across all three projects, the authors are interested in roles and responsibilities of data services and data repositories that support concepts of policies and customization.

description: In this article, I argue that the concept of urban livability is used as a political tool by the Singaporean state to further its pursuit of global city status. I show how the state uses neighborhood “upgrading” as a mechanism to inscribe strategic meanings of livability onto Singapore’s residential landscapes with the expectation that residents will align their experiences of livability with the former. I use an embodied approach to analyze state manipulation of two residential landscapes—condominiums and public housing—as an active means of official attempts to create two types of citizen-subjects. By juxtaposing the state’s operationalization of livability against livability as understood in the context of residents’ localized lifeworlds, I show how indeterminate outcomes arise from the state’s livability project.
Magnetic imaging of intrinsic magnetic topological materials

description: Recently synthesized Mn(Bi/Sb)2n(Se/Te)3n+1-family van der Waals compounds incorporate intrinsic magnetism and topologically nontrivial band structure, providing ideal platforms to investigate many fascinating quantum phenomena. Examples include quantum anomalous Hall (QAH) effect, axion insulator state, and Weyl semimetal phases. Different members in the Mn(Bi/Sb)2n(Se/Te)3n+1 family exhibit distinct magnetic orders, yet comprehensive studies about their domain behavior and associated magnetic phase transitions have been lacking. In this thesis, we focus on cryogenic magnetic force microscopy (MFM) study on several Mn(Bi/Sb)2n(Se/Te)3n+1 compounds. In chapter 3, we report direct visualization of spin-flip transition of the surface layer in antiferromagnet MnBi4Te7, a natural superlattice of alternating MnBi2Te4 and Bi2Te3 layers. The observation of magnetic contrast across domain walls and step edges confirms that the antiferromagnetic order persists to the surface layers. The magnetic field dependence of the MFM images reveals that the surface magnetic layer undergoes a first-order spin-flip transition at a magnetic field that is lower than the bulk transition, in excellent agreement with a revised Mills model. Our analysis suggests no reduction of the order parameter in the surface magnetic layer, implying robust ferromagnetism in the single-layer limit. The direct visualization of surface spin-flip transition not only opens up exploration of surface metamagnetic transitions in layered antiferromagnets, but also provides experimental support for realizing quantized transport in ultrathin films of MnBi4Te7 and other natural superlattice topological magnets. In chapter 4, we report the magnetic imaging of two kinds of defect engineered MnSb2Te4 single crystal. For the ferromagnetic MnSb2Te4, the magnetic field dependence of the domains reveals very weak pinning of domain walls in MnSb2Te4, resulting in a negligibly small magnetic hysteresis loop. The temperature dependence of the domain contrast reveals a mean field like behavior, in good agreement with that of bulk magnetization measurements. For the MnSb2Te4 with competing phases, we visualize a temperature driven ferromagnetic-antiferromagnetic transition. The nucleation of magnetic domains in the transition shows no preference at the domain wall, indicating negligible energy difference between the competing phases. The MFM data for warming and cooling exhibits distinct features, suggesting a surface-to-bulk transition process. Our MFM results not only unveil the elusive surface magnetism in some natural antiferromagnetic superlattices but also provides key ingredient for the control and manipulation of the magnetic order in Mn(Bi/Sb)2n(Se/Te)3n+1-family compounds, opening a new path toward the realization of exotic quantum phases in intrinsic topological insulators.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: An acyclic coloring of a digraph as defined by Neumann-Lara is a vertex-coloring such that no monochromatic directed cycles occur. Counting the number of such colorings with $k$ colors can be done by counting so-called Neumann-Lara-coflows (NL-coflows), which build a polynomial in $k$. We will present a representation of this polynomial using totally cyclic subdigraphs, which form a graded poset $Q$. Furthermore we will decompose our NL-coflow polynomial, which becomes the chromatic polynomial of a digraph by multiplication with the number of colors to the number of components, examining the special structure of the poset of totally cyclic subdigraphs with fixed underlying undirected graph. This decomposition will confirm the equality of our chromatic polynomial of a digraph and the chromatic polynomial of the underlying undirected graph in the case of symmetric digraphs.
On the geometry outside of acoustic black holes in $2+1$-dimensional spacetime

description: Analogue black holes, which can mimic the kinetic aspects of real black holes, have been proposed for many years. The growth of the radial momentum of test particles toward the acoustic horizon is calculated for acoustic black holes in flat and curved spacetimes. Surprisingly, for a freely infalling vortex approaching the acoustic black hole, the Lyapunov exponent of the growth of the momentum at the horizon saturates the chaos bound $Λ_{\rm Lyapunov}\leq 2 πT$. We investigate the orbits of test vortices and sound wave rays in the $2+1$-dimensional "curved" spacetime of an acoustic black hole. We show that the vortices orbit, the sound wave orbit, and the time delay of sound are similar to those famous effects of general relativity. These effects can be verified experimentally in future experiments.

description: Like many of the earth’s natural resources, humankind has mistakenly viewed the ocean as having an infinite supply of reserves to satisfy our needs and wants. This has made the waters of our globe vulnerable to overexploitation and, as a consequence, many ocean species are now declining at an alarming and unsustainable rate. The sawfishes are one such group of species, and are now recognised as being among the most threatened marine species, facing a rapid descent to extinction if immediate action is not taken to address the severity of their plight. The wonderful morphology of these species, with their long, highly distinctive tooth-nosed snout, makes them a truly striking and iconic image of our seas. Unfortunately, this unique feature has sadly been the cause of their own ruin, being both easily entangled in net and highly-prized for medicinal and cultural purposes and sold as curios for the tourist trade. Other threats to the sawfishes are common to many marine species and include overfishing and habitat destruction. As a result, sawfishes are now one of the most threatened families of marine species on the IUCN Red List of Threatened Species™. Conservation must be built on sound knowledge and scientific research. The IUCN Species Survival Commission (SSC) is a science-based network of more than 8,000 volunteer experts from over 160 countries. SSC members are deployed in over 130 Specialist Groups, and it is one of these groups – the IUCN Shark Specialist Group – that has prioritised sawfishes for urgent conservation action and has ably led the way in designing a focused global strategy to provide the best possible scientific basis to secure the survival of these iconic species. The SSC Conservation Action Plan series has been one of the world’s most respected sources of information on species and their conservation needs. Since the mid-1980s, the SSC has published more than 60 Action Plans for some of the world’s most charismatic species. Recently, the SSC has developed a new process better able to link science and management for the effective delivery of conservation action. The formerly known Action Plans are now known as Species Conservation Strategies. This past decade has been characterised by our growing alarm of the state of the oceans. However, we are now in a position where we can move from describing the status to actually doing something about it. This Global Sawfish Conservation Strategy is a crucial step on the path to conserving one of the most threatened families of marine fishes, the iconic sawfishes.

description: Multiphase flow dynamics are integral to many propulsion, sprays, energetics, and industrial processes. Practical systems, especially in combustion, typically involve multidimensional spatial structures and complex and coupled physics interactions. At some operating conditions, flow mixing, combustion chemical reactions, and flow residence time scales are relatively similar and therefore coupled (i.e., each affects the other). For example, the combustion and atomization of liquid fuel govern the performance of combustors. In addition to spray-air interactions, injection strategies may rely on spray-wall interactions to achieve improved mixing and performance. Understanding and predicting these flows requires advanced experimental diagnostics that provide information on local state variables with high spatiotemporal resolution. However, multiphase flow dynamics integral to these combustion systems may not be fully resolved with conventional one or two-dimensional diagnostics. Tomographic reconstructions yield 3D spatial information and may provide high-fidelity data to fill the technology gap. Performing these 3D diagnostics with adequate time-resolution is necessary to capture the full dynamics of high-speed flows. This work focuses on developing, applying, and evaluating non-intrusive 4D (x,y,z,t) volumetric imaging in challenging combustion environments. Each optical diagnostic approach probes a different phase of combustion experiments in a non-instructive manner. For example, Schlieren imaging visualizes the index of refraction gradients corresponding to density changes in the gas phase. This work uses various optical approaches (e.g., scattering, Schlieren, or fluorescence) with 4D imaging to provide quantitative measurements of different combustion phenomena. Parallel ray-tracing simulations are utilized to guide diagnostic development and quantify measurement capabilities. This work presents significant high-speed diagnostic improvements for combustion applications relevant to defense, energy generation, and propulsion.
