description: We investigate the thermodynamic and transport properties of the real scalar field theory at weak as well as strong couplings in the Hartree approximation of Cornwall-Jackiw-Tomboulis (CJT) formalism. To our surprise, we find that near phase transition, all the thermodynamic and transport properties of the simplest real scalar model at certain strong coupling agree well with the lattice results of the complex QCD system. We also demonstrate that the system near phase transition is non-conformal, and behaves as a non-perfect fluid.

description: With high incidences of population growth, increasing food deficits, soaring demands for food and the various environmental challenges has necessitated that agriculture and food production scale up to become issue of international, political, policy and research agenda. There are various projections that the global population might increase to 9billion by 2050 and such increase will be prominent in Asia, Latin America and in Sub-Saharan Africa. One of the greatest concern is that to meet the increasing need for food amongst the population, at least 60% increase in food production is necessary to need the need of the population. Research and innovation in agricultural engineering is crucial in overcoming the major challenges caused by global changes taking place now. This paper is aimed at guiding policy decisions in education and it seeks to provide an investigation into research and innovation in agricultural engineering in a university in KwaZulu-Natal. This study explored the nature of research and innovation in a university in KwaZulu-Natal. To provide answers to the research questions, a literature review was carried out to locate researches made in agricultural engineering in a university in KwaZulu-Natal between year 1988 to 2016. Research and innovation in agricultural engineering is categorized along four dimensions which are optimizing and Regulating combustion in compression ignition engines, energy use and Post-harvest management of sugarcane, Small holder Irrigation and small scale water infrastructure in South Africa, Climate issues and the extension need of smallholder farmers in South Africa. This study recommended that there is a need to have a change to research and innovation in agricultural engineering in a university in KwaZulu-Natal due to changing context and conduct of events. With the sustainable development goals and many challenging issues to deal with, there should be a focus on fourth industrial revolution and its application to agricultural engineering, climate change issues, gender issues in agricultural engineering, food security and sustainability of food crop production etc.

description: The axial form factor of the nucleon is studied in a two-component model consisting of a three-quark intrinsic structure surrounded by a meson cloud. The experimental data in the space-like region are well reproduced with a minimal number of parameters. The results are similar to those obtained from a dipole fit up to 1 GeV$^2$, but they surprisingly show a zero between 2 and 3 GeV$^2$. Such behavior, predicted by the present model completely disagrees with the dipole parametrization. The theoretical expression for the form factor is then analytically extrapolated to the time-like region, giving the first predictions in this regime. This kinematical region is especially interesting for present and future colliders.

description: In this paper we study the problem of model reduction by moment matching for stochastic systems. We characterize the mathematical object which generalizes the notion of moment to stochastic differential equations and we find a class of models which achieve moment matching. However, differently from the deterministic case, these reduced-order models cannot be considered "simpler" because of the high computational cost paid to determine the moment. To overcome this difficulty, we relax the moment matching problem in two different ways and we present two classes of reduced-order models which, approximately matching the stochastic moment, are computationally tractable.

description: Nella letteratura linguistica moderna è possibile individuare almeno tre  approcci all'analisi del verso tradizionale cinese (cosiddetto  "regulated"): l'approccio lineare, l'approccio dell'albero metrico, e  l'approccio della griglia metrica. Sebbene nessuno di questi riesca a  spiegare in modo adeguato tutti gli aspetti di questo tipo di verso un  approccio ad albero (alla Chen [1979], con modificazioni proposte da Yip  [1980]) e da Xue [1989]) è il migliore per quanto riguarda il sistema  ritmico, mentre un approccio lineare (proposto qui) è il migliore per  quanto riguarda il sistema tonale.

description: A recent measurement of the proper motion of PSR J0908-4913 shows that it is a fast moving object at a distance of some 3 kpc. Here we present evidence that the pulsar is located at the edge of a previously unknown, filled-centre supernova remnant, G270.4-1.0. The velocity vector of the pulsar points directly away from the centre of the remnant. The putative association of the pulsar with SNR G270.4-1.0 implies the pulsar is ~12kyr old, significantly less than its characteristic age of 110kyr. We show that the rotation axis of the pulsar points in the direction of the proper motion. Rotation measure and dispersion measure variations are seen over time, likely indicating the pulsar is passing behind a filament of the remnant.

description: We report a dynamic light scattering study on protein suspensions of bovine lens homogenates at conditions (pH and ionic strength) similar to the physiological ones. Light scattering data were collected at two temperatures, 20 oC and 37 oC, over a wide range of concentrations from the very dilute limit up to the dense regime approaching to the physiological lens concentration. A comparison with experimental data from intact bovine lenses was advanced revealing differences between dispersions and lenses at similar concentrations. In the dilute regime two scattering entities were detected and identified with the long-time, self-diffusion modes of alpha-crystallins and their aggregates, which naturally exist in lens nucleus. Self-diffusion coefficients are temperature insensitive, whereas the collective diffusion coefficient depends strongly on temperature revealing a reduction of the net repulsive interparticle forces with lowering temperature. While there are no rigorous theoretical approaches on particle diffusion properties for multi-component, non-ideal hard-sphere, polydispersed systems, as the suspensions studied here, a discussion of the volume fraction dependence of the long-time, self-diffusion coefficient in the context of existing theoretical approaches was undertaken. This study is purported to provide some insight into the complex light scattering pattern of intact lenses and the interactions between the constituent proteins that are responsible for lens transparency. This would lead to understand basic mechanisms of specific protein interactions that lead to lens opacification (cataract) under pathological conditions.

description: Massive stars deeply influence their surroundings by their luminosity and the injection of kinetic energy. So far, they have mostly been studied with spatially unresolved observations, although evidence of geometrical complexity of their wind are numerous. Interferometry can provide spatially resolved observations of massive stars and their immediate vicinity. Specific geometries (disks, jets, latitude-dependent winds) can be probed by this technique. The first observation of a Wolf-Rayet (WR) star (γ^2 Vel) with the AMBER/VLTI instrument yielded to a re-evaluation of its distance and an improved characterization of the stellar components, from a very limited data-set. This motivated our team to increase the number of WR targets observed with AMBER. We present here new preliminary results that encompass several spectral types, ranging from early WN to evolved dusty WC. We present unpublished data on WR79a, a massive star probably at the boundary between the O and Wolf- Rayet type, evidencing some Wolf-Rayet broad emission lines from an optically thin wind. We also present new data obtained on γ^2 Vel that can be compared to the up-to-date interferometry-based orbital parameters from North et al. (2007). We discuss the presence of a wind-wind collision zone in the system and provide preliminary analysis suggesting the presence of such a structure in the data. Then, we present data obtained on 2 dusty Wolf-Rayet stars: WR48a-b and WR118, the latter exhibiting some clues of a pinwheel-like structure from the visibility variations.

Family limitation in Lancashire : an environmental problem, 1832-1911
Creators: name: Reimer, Hilrie
Publisher: name: University of British Columbia
Year: 2010

description: In nineteenth-century Lancashire, reproductive complications as a result of cotton dust exposure were either ignored or misunderstood largely because moral and economic concerns tended to overshadow the health issues involved. Debate in the first half of the century over who should be responsible for the industrial poor and the subsequent controversy over the diminishing birth rate, particularly among textile workers, helped bring health issues into focus by the turn of the century. A comparison of dusty mills with ideally ventilated mills indicates that contemporary observers were of the impression that families involved in the latter were larger and healthier than those that were employed in the former. The testimony of working women also attributes reproductive problems to poor health caused by their work. Ailments associated with cotton dust exposure had been recognized early in the course of the debates but the concept of a disease specific to cotton dust inhalation and related reproductive impairment was not defined until well into the twentieth century.

description: Present theories of irreversible energy losses and heat generation within Li-ion cells are unsatisfactory because they are not compatible with energy conservation. This work aims to provide a consistent theoretical treatment of energy transport and losses in such devices. An energy conservation law is derived from the Doyle-Fuller-Newman (DFN) model of a Li-ion cell using a rigorous mathematical approach. The resulting law allows irreversible chemical energy losses to be located to seven different regions of the cell, namely: (i) the electrolyte, (ii) the anode particles, (iii) the cathode particles, (iv) the solid parts of the anode (ohmic losses), (v) the solid parts of the cathode (ohmic losses), (vi) the surfaces of the anode particles (polarisation losses), and (vii) the surfaces of the cathode particles (polarisation losses). Numerical solutions to the DFN model are used to validate the conservation law in the cases of a drive cycle and constant current discharges, and to compare the energy losses occurring in different locations. It is indicated how cell design can be improved, for a specified set of operating conditions, by comparing the magnitude of energy losses in the different regions of the cell.

description: We combine mid-infrared diagnostics obtained from integral-field unit observations taken with MIRI/MRS on JWST with cold molecular gas information derived from ALMA observations of CO(1-0) emission to investigate the star formation rate and efficiency within the central $\sim$ 1.5 kpc$\times$1.3 kpc region of the Seyfert 1 galaxy NGC 7469 on $\sim$ 100 pc scales. The active nucleus leaves a notable imprint on its immediate surroundings by elevating the temperature of the warm molecular gas, driving an ionized gas outflow on sub-kpc scales, and selectively destroying small dust grains. These effects, nevertheless, have relatively little impact on the cold circumnuclear medium or its ability to form stars. Most of the star formation in NGC 7469 is confined to a clumpy starburst ring, but the star formation efficiency remains quite elevated even for the nuclear region that is most affected by the active nucleus.

description: Despite advances in the programmable logic capabilities of modern trigger systems, a significant bottleneck remains in the amount of data to be transported from the detector to off-detector logic where trigger decisions are made. We demonstrate that a neural network autoencoder model can be implemented in a radiation tolerant ASIC to perform lossy data compression alleviating the data transmission problem while preserving critical information of the detector energy profile. For our application, we consider the high-granularity calorimeter from the CMS experiment at the CERN Large Hadron Collider. The advantage of the machine learning approach is in the flexibility and configurability of the algorithm. By changing the neural network weights, a unique data compression algorithm can be deployed for each sensor in different detector regions, and changing detector or collider conditions. To meet area, performance, and power constraints, we perform a quantization-aware training to create an optimized neural network hardware implementation. The design is achieved through the use of high-level synthesis tools and the hls4ml framework, and was processed through synthesis and physical layout flows based on a LP CMOS 65 nm technology node. The flow anticipates 200 Mrad of ionizing radiation to select gates, and reports a total area of 3.6 mm^2 and consumes 95 mW of power. The simulated energy consumption per inference is 2.4 nJ. This is the first radiation tolerant on-detector ASIC implementation of a neural network that has been designed for particle physics applications.

Resistive Hot Accretion Flows with Anisotropic Pressure

description: Since the collisional mean free path of charged particles in hot accretion flows can be significantly larger than the typical length-scale of the accretion flows, the gas pressure is anisotropic to magnetic field lines. For such a large collisional mean free path, the resistive dissipation can also play a key role in hot accretion flows. In this paper, we study the dynamics of resistive hot accretion flows in the presence of anisotropic pressure. We present a set of self-similar solutions where the flow variables are assumed to be a function only of radius. Our results show that the radial and rotational velocities and the sound speed increase considerably with the strength of anisotropic pressure. The increase in infall velocity and in sound speed are more significant if the resistive dissipation is taken into account. We find that such changes depend on the field strength. Our results indicate that the resistive heating is $10\%$ of the heating by the work done by anisotropic pressure when the strength of anisotropic pressure is 0.1. This value becomes higher when the strength of anisotropic pressure reduces. The increase in disk temperature can lead to heating and acceleration of the electrons in such flows. It helps us to explain the origin of phenomena such as the flares in Galactic Center Sgr A*.

Amadas et Ydoine, the search for inner and outer harmony
Creators: name: Mearns, Barbara Lucille
Publisher: name: University of British Columbia
Year: 2010

description: Amadas et Ydoine, a romance written between 1190 and 1220, describes "pure" love and all the obstacles it can overcome. The central concern of this work is the resolution of conflict in order to attain harmony and union on both a social and personal level. Written during the transition period between the 12th and 13th centuries, the romance reflects many changing and conflicting attitudes of the time, especially those concerning women. In these I examine the romance and the part women play in it on three different levels: the intertextual, the narrative perspective and the psychological. On the intertextual level, I compare Amadas et Ydoine with Tristan et Iseult to show that the author is trying to create a type of transcendent-Tristan. His variances of the accepted "perfect" romance of the time reveal his opinions about women and sexual roles. In Chapter 2, I examine the integral part played by the narrator. He is an extremely ambiguous personage who manages to praise Ydoine perpetually while describing her several acts of deception. At the same time he denounces women as a group while offering no proof of his accusations. I examine his portrayal of Ydoine and the inconsistent nature of his periodic interruptions of the narration. In Chapter 3, I look at the actions of Amadas in the light of Jungian and "Campbellian" concepts. I see his maturation process as being what Jung calls the individuation process and what Campbell labels the hero voyage. I consider the steps Amadas takes in order to bring to a conscious level his anima, or feminine principle, as being the major part of his maturation. Amadas et Ydoine is a romance of struggle, but one in which social and personal harmony are finally achieved. The bridge of those two types of harmony is the female. On the intertextual level, it is Ydoine who guides Amadas and who motivates him to guard their vital connection to the macrocosmos. On the psychological level, it is the anima who guides Amadas, helps him face his unconscious, surrender his ego, and molds him into a well-rounded personality. The narrator incarnates opposing views of both the 12th and 13th centuries, and by doing so reveals how impossible and ridiculous those extreme attitudes about women actually are. Consequently, the romance can be regarded as a re-enactment of coming to terms with our unconscious, healing the conflict with the contrasexual component of our beings, which in turn helps to heal the split between male and female on a social level and results in both internal and external harmony.

description: Microwave power absorption by a two-layer system deposited on a metallic surface has been studied in the experimental setup emulating the response to a radar signal. Layers containing hexaferrite and iron powder in a dried paint of thickness under 1mm have been used. The data is analyzed within a theoretical model derived for a bilayer system from the transmission line theory. A good agreement between experimental and theoretical results is found. The advantage of using a bilayer system over a single-layer system has been demonstrated. How the maximum microwave absorption (minimum reflection loss) can be achieved through the optimization of the filling factors and thicknesses of the two layers is shown.

description: A family of vector fields that are the infinitesimal generators of determined one-parameter groups of transformations are constructed. It is shown that these vector fields represent symmetries of the system of differential equations interrelated by the axially symmetric Laplace equation and a certain supplementary equation. Group-invariant solutions of this system of equations are obtained by means of two alternative methods, and it is proved that these solutions turn out to be the family of axisymmetric potentials related to specific gravitational multipoles. The existence of these symmetries provides us with a generalization of the fact that the Newtonian Monopole is defined by the solution of the Laplace equation with spherical symmetry, and it allows us to extract from all solutions of this equation those with the prescribed Newtonian Multipole Moments.

description: Every major healthcare system is now under the throes of the Coronavirus disease outbreak as it is operating at its maximum capacity. There is an absolute need to establish an appropriate cure for this virus as quickly and efficiently as possible. Advances in deep learning models may play a critical role in SARS-2 discovery by locating a possible treatment. This article's objective is to demonstrate the machine learning and deep learning models approaches for classifying prospective coronavirus treatment on a single human cell. A partial dataset of RXRX.ai which is a publicly available dataset is used in this research. This work targeted to implement a strategy for automatically identifying a single human cell depending on the type of treatment and its concentration level. Throughout this study, we present a DCNN model along with an image processing approach. The systematic approach comprises translating the original dataset's numerical attributes to the image domain, and then incorporating them into DCNN model. In comparison to standard machine learning techniques including such Ensemble, Decision Tree and Support Vector Machine, the experimental findings indicate that the suggested DCNN model for treatment classification (32 categories) obtained a testing accuracy of 98.05 percent. The (Ensemble) algorithm achieves 98.5 percent for the accuracy test in treatment concentration level prognosis, whereas the suggested DCNN model reached 98.2 percent. The classification of treatments and assessing their concentration levels are considerably accurate due to the performance indicators obtained from the experiments. © 2021 Little Lion Scientific.

We don't know when was it written: perhaps in 1930. However, its central theme was still alive in Majorana's mind in 1934: in fact, on July 27, 1934, he will write to G.Gentile Jr. to expect that <>.

Assessment of bacteriophage-insensitive culture bacteria for cheddar cheese making and subsequent discriminant analysis for objective flavour evaluation
Creators: name: Amantea, Gerald Fiore

description: The first part of this two-part study deals with six defined strains of bacteriophage-insensitive Streptococcus cremoris used over a period of 10 months to produce more than 2 million kg of Cheddar cheese on continuous cheesemaking equipment. Flavour development in this cheese was less than that in cheese made with conventional bulk starter. Proteolysis and Theological properties were examined. Pattern recognition techniques were used to analyze the multivariate data. Texture was affected by the mechanical process, moisture content and yield point. Casein proteolysis, age, culture type and firmness were the most discriminating variables affecting maturity. In part two, it is well recognized that a minimum maturation period is required before Cheddar cheese is acceptable to the consumer. This is a lengthy and costly procedure in which quality is based on subjective evaluation. Classically, trained graders and sensory panels have performed this duty, but because of the variable, subjective and time consuming nature or organoleptic methods, a simple, more objective and reliable method for accurately assessing cheese flavour is proposed. Sensory evaluations by trained graders were done on more than 60 commercially produced cheese samples, and water soluble fractions prepared from all samples. A ternary gradient system was used to elute the non-volatile flavour components from an Adsorbosphere C₈ reverse phase column. A new mapping simplex optimization technique was applied to the HPLC profiles to optimize separation of the multi-component mixture. More than 45 peaks were obtained using an initial solvent volume ratio of 44.6:0:55.4 of trifluoroacetic acid (0.1%), acetonitrile and water. Over 56.6 min the ratio was changed to 0:36.6:63.4 at a flow-rate of 0.97 mi/min. The optimized gradient system was superior to previous isocratic separations and the elution patterns differed for the various categories of cheese. Statistical pattern recognition techniques - principal component analysis and stepwise linear discriminant analysis - were used to interpret the HPLC profiles. Cheese samples were correctly classified according to their discriminant functions into groups. The technique differentiated between first grade and downgraded samples and was capable of assessing cheese flavour quality at an early age.

(Figs. 1–9)
 Material examined. Holotype male, Mro oua Chirini (Soulou River), Mayotte, Comoros, 12°46'40,26" S 45°6'15,16" E, 16 May 2006, leg. N. Mary (MNHN).
 Diagnosis. Pore-bearing plates of dorsum rhomboid, cheliceral claw long and straight, genital field with eight pairs of acetabula.
 Description. Male: Idiosoma 1025 long, 689 wide, anteriorly truncated; integument papillate. Porebearing plates of dorsum rhomboid, especially in posterior part of dorsum, but in some anterior parts these plates obliterated. Pore-bearing plates surrounding dorsoglandularia and lateroglandularia. Ventral porebearing plates more irregularly shaped, and partly obliterated. Anterior tips of first and second coxal plates with 4–5 short setae. Near anterior margin of third coxal plates 1–2 setae. Genital field 168 long, 190 wide, with nine pairs of acetabula, anterior pair larger and separated from eight posterior pairs. Genital flaps with a row of small setae near medial margin, more posteriorly 2–3 pairs of longer setae. Excretory pore halfway between genital field and posterior idiosoma margin. Lengths PI-PV: 50, 64, 58, 132, 42. Palp segments slender, PII ventrally with two pinnate setae (one seta broken off in one of the palps), dorsal margin of PI and PIII with one seta, dorsal margin of PII with three setae. Ventral margin of PIV distally with one hair-like setae (Figs. 5–6). Cheliceral claw slender, 218 long. Lengths of I-Leg-4–6: 124, 142, 120; I-Leg-6 distally with three spatulate setae. Lengths of IV-Leg-4–6: 226, 224, 172. All leg claws with a prominent comb.
Female: Unknown.
 Etymology. Named for the rhomboid pore-bearing plates of the dorsum.
 Remarks. K.O. Viets (in K.O Viets & Böttger 1974) erected the subgenus Rhynchohansvietsia, based on the shape of the capitulum. Due to fixation in ethanol, it was not possible to detach the capitulum of T. scutulatus and therefore its shape could not be ascertained. Subgeneric assignment was therefore impossible. The extremely long cheliceral claw is only found in T. congoensis K.O. Viets, 1974 and T. sagariphoris Cook, 1966. The new species differs from T. congoensis in the slender palp, from T. sagariphoris Cook in the lower number of acetabula and differently shaped dorsal pore-bearing plates.

description: We characterize parallel double quantum dot Josephson junctions based on closely-grown double nanowires bridged by in-situ deposited superconductors. The parallel double dot behavior occurs despite the closeness of the nanowires and the potential risk of nanowire clamping during growth. By tuning the charge filling and lead couplings, we map out the simplest parallel double quantum dot Yu-Shiba-Rusinov phase diagram. Our quasi-independent two-wire hybrids show promise for the realization of exotic topological phases.

description: Every major healthcare system is now under the throes of the Coronavirus disease outbreak as it is operating at its maximum capacity. There is an absolute need to establish an appropriate cure for this virus as quickly and efficiently as possible. Advances in deep learning models may play a critical role in SARS-2 discovery by locating a possible treatment. This article's objective is to demonstrate the machine learning and deep learning models approaches for classifying prospective coronavirus treatment on a single human cell. A partial dataset of RXRX.ai which is a publicly available dataset is used in this research. This work targeted to implement a strategy for automatically identifying a single human cell depending on the type of treatment and its concentration level. Throughout this study, we present a DCNN model along with an image processing approach. The systematic approach comprises translating the original dataset's numerical attributes to the image domain, and then incorporating them into DCNN model. In comparison to standard machine learning techniques including such Ensemble, Decision Tree and Support Vector Machine, the experimental findings indicate that the suggested DCNN model for treatment classification (32 categories) obtained a testing accuracy of 98.05 percent. The (Ensemble) algorithm achieves 98.5 percent for the accuracy test in treatment concentration level prognosis, whereas the suggested DCNN model reached 98.2 percent. The classification of treatments and assessing their concentration levels are considerably accurate due to the performance indicators obtained from the experiments. © 2021 Little Lion Scientific.

description: The electron-photon interaction (the spinor-vector field interaction) in the de Sitter ambient space formalism is investigated in the first (leading order) approximation. The interaction Lagrangian and the scattering matrix are presented. In this approximation, the scattering matrix can be written as a expansion of the interaction Lagrangian. The tree-diagram of electron-photon scattering amplitude is calculated. Finally the Minkowski limit is considered.

The Farakka Barrage dispute : conflict and cooperation in Bangladesh-India relations
Creators: name: Mamun, Kazi Asadul
Publisher: name: University of British Columbia
Year: 2010

description: The origins of the Farakka Barrage dispute go back as far as 1951 when Pakistan protested against the Government of India's plans to construct a massive barrage across the Ganges River only eleven miles from the East Pakistan border. Pakistan, and since 1971 Bangladesh, argued that Indian diversion of Ganges water would seriously threaten the agrarian economy and the overall ecology of the lower delta. Although two interim agreements on sharing of Ganges waters have been reached between India and Bangladesh, these agreements have not covered all aspects of riverine development. As a result, the conflict has continued and as of 1984, no solution is imminent. Two analytical approaches -- to international river disputes and to power relations between unequal states — are helpful in explaining the Farakka Barrage dispute. The international river dispute literature explains why there is a dispute at all, what hydrologic-economic factors make this dispute difficult to resolve, and why India and Bangladesh have presented the types of proposals they have for developing the river basin. Analysis based on unequal power relationship (the "asymmetric dyad") which exists between these two states reveals the superordinate position of India which, in addition to being the more powerful state, is also the upper riparian. Therefore, the strategies that Bangladesh — as the subordinate state and the lower riparian — can employ are limited. This thesis outlines in considerable detail the political as well as the hydrologic-economic aspects of the dispute and tries to demonstrate the correlation of overall power relations between India and Bangladesh with the political strategies they employ. The main argument is that both India and Bangladesh have acted according to their interpretation of the political costs and benefits involved in resolving the dispute. Bangladesh, for its part, has pursued a variety of strategies ranging from cooperative to retaliatory in an attempt to secure what it considers an equitable solution. Each of these strategies is analysed in turn for its effectiveness. Overall, although periodically Bangladesh has been able to extract marginal concessions from India, the latter, because of its predominant political-economic position, has controlled the direction of negotiations over sharing and augmentation of Ganges waters.

description: Temperature dependence of the longitudinal and Hall resistance is studied in the regime of localization-delocalization transition. We carry out measurements of a scaling exponent $κ$ in the Landau level mixing region at several filling factors. The localization exponent $γ$ is extracted using an approach based on the variable range hopping theory. The values of $γ$ and $κ$ are found to be universal, independent of filling factor in our sample. We can conclude that although Landau level mixing can change the degeneracy of a quantum Hall state, the value of the scaling exponent remains the same for a given sample that contains a fixed disorder profile.

description: We present new parameterizations of vector and axial nucleon form factors. We maintain an excellent descriptions of the form factors at low momentum transfers ($Q^2$), where the spatial structure of the nucleon is important, and use the Nachtman scaling variable $ξ$ to relate elastic and inelastic form factors and impose quark-hadron duality constraints at high $Q^2$ where the quark structure dominates. We use the new vector form factors to re-extract updated values of the axial form factor from $\numu$ experiments on deuterium. We obtain an updated world average value from $\numu$d, $\numubar$H and pion electroproduction experiments of $M_{A}$ = $1.014 \pm 0.014 GeV/c^2$. Our parameterizations are useful in modeling $ν$ interactions at low energies (e.g. for $\numu$ oscillations experiments). The predictions for high $Q^2$ can be tested in the next generation electron and $\numu$ scattering experiments.
