description: In his 2007 monograph, D. Christodoulou proved a remarkable result giving a detailed description of shock formation, for small $H^s$-initial conditions ($s$ sufficiently large), in solutions to the relativistic Euler equations in three space dimensions. His work provided a significant advancement over a large body of prior work concerning the long-time behavior of solutions to higher-dimensional quasilinear wave equations, initiated by F. John in the mid 1970's and continued by S. Klainerman, T. Sideris, L. Hörmander, H. Lindblad, S. Alinhac, and others. Our goal in this paper is to give an overview of his result, outline its main new ideas, and place it in the context of the above mentioned earlier work. We also introduce the recent work of J. Speck, which extends Christodoulou's result to show that for two important classes of quasilinear wave equations in three space dimensions, small-data shock formation occurs precisely when the quadratic nonlinear terms fail the classic null condition.

description: Most of the known methods for estimating the fractal dimension of fractal sets are based on the evaluation of a single geometric characteristic, e.g. the volume of its parallel sets. We propose a method involving the evaluation of several geometric characteristics, namely all the intrinsic volumes (i.e.\ volume, surface area, Euler characteristic etc.) of the parallel sets of a fractal. Motivated by recent results on their limiting behaviour, we use these functionals to estimate the fractal dimension of sets from digital images. Simultaneously, we also obtain estimates of the fractal curvatures of these sets, some fractal counterpart of intrinsic volumes, allowing a finer classification of fractal sets than by means of fractal dimension only. We show the consistency of our estimators and test them on some digital images of self-similar sets.

Exploring the 'Birch effect' in reservoir sediments: influence of inundation history on aerobic nutrient release

description: Murray-Darling Freshwater Research Centre

MDFRC item.

The release of nutrients on wetting ('the Birch effect') is well documented for terrestrial soils. The effect for aquatic sediments has received much less attention. An extreme drawdown event in a large reservoir during a period of drought presented an opportunity to test whether or not reflooding dried sediments would be a source of nutrients to the overlying water column. Wetting and drying history influences the release of ammonium, but not oxides of nitrogen, organic nitrogen, filterable reactive phosphorus or total phosphorus, from dried sediments following re-wetting. Dried reservoir sediments that have never, or have only rarely, been desiccated since the 1920s produced a pulse of ammonium on re-inundation. Conversely, dried sediments from parts of the reservoir that undergo frequent wetting and drying cycles do not release substantial amounts of ammonium on rewetting.

description: Tra le possibili contaminazioni disciplinari in campo artistico, quella tra l’arte del progetto e la produzione musicale è in assoluto una tra la più proficue e ricche di valori storico-culturali. Esistono molti musicisti che hanno studiato da progettisti e viceversa: Iannis Xenakis, Demetrio Stratos, Edoardo Bennato, Claudio Baglioni, Lorenzo Palmeri. Il citato Xenakis propose nella sua teoria meta-artistica il concetto secondo il quale un'espressione artistica basata su un calcolo matematico può essere realizzata indifferentemente dal tipo di media utilizzato. Ma non possiamo limitarci al mezzo: architettura e musica non sono solo matematica. Un’analisi approfondita delle caratteristiche attitudinali, comportamentali, di approccio tecnico tra i due ambiti rivela che spesso non si tratta solo di contaminazione, ma che tra il progettista (architetto, designer, …) e il musicista esistono profonde affinità.
description: Among the possible disciplinary contaminations in the artistic field, that between the art of design and musical production is by far one of the most fruitful and rich in cultural-historical values. There are many musicians who have studied as designers and vice versa: Iannis Xenakis, Demetrio Stratos, Edoardo Bennato, Claudio Baglioni, Lorenzo Palmeri. The aforementioned Xenakis proposed in his metaartistic theory the concept that an artistic expression based on mathematical calculation can be realized regardless of the type of media used. But we cannot limit ourselves to the medium: architecture and music are not just mathematics. A thorough analysis of the attitudinal, behavioral, and technical characteristics between the two fields reveals that it is often not just a matter of contamination, but that deep affinities exist between the designer and the musician.
Hierarchy and size distribution function of star formation regions in the spiral galaxy NGC 628

description: Hierarchical structures and size distribution of star formation regions in the nearby spiral galaxy NGC 628 are studied over a range of scale from 50 to 1000 pc using optical images obtained with 1.5 m telescope of the Maidanak Observatory. We found hierarchically structured concentrations of star formation regions in the galaxy, smaller regions with a higher surface brightness are located inside larger complexes having a lower surface brightness. We illustrate this hierarchy by dendrogram, or structure tree of the detected star formation regions, which demonstrates that most of these regions are combined into larger structures over several levels. We found three characteristic sizes of young star groups: 65 pc (OB associations), 240 pc (stellar aggregates) and 600 pc (star complexes). The cumulative size distribution function of star formation regions is found to be a power law with a slope of approximately -1.5 on scales appropriate to diameters of associations, aggregates and complexes. This slope is close to the slope which was found earlier by B. Elmegreen et al. for star formation regions in the galaxy on scales from 2 to 100 pc.

description: We use polarized inelastic neutron scattering (INS) to study spin excitations in superconducting NaFe0.985Co0.015As (C15) with static antiferromagnetic (AF) order along the a-axis of the orthorhombic structure and NaFe0.935Co0.045As (C45) without AF order. In previous unpolarized INS work, spin excitations in C15 were found to have a dispersive sharp resonance near Er1=3.25 meV and a broad dispersionless mode at Er2=6 meV. Our neutron polarization analysis reveals that the dispersive resonance in C15 is highly anisotropic and polarized along the a- and c-axis, while the dispersionless mode is isotropic similar to that of C45. Since the a-axis polarized spin excitations of the anisotropic resonance appear below Tc, our data suggests that the itinerant electrons contributing to the magnetism are also coupled to the superconductivity.

Organic magnetoresistance from deep traps

description: We predict that singly-occupied carrier traps, produced by electrical stress or irradiation within organic semiconductors, can cause spin blockades and the large room-temperature magnetoresistance known as organic magnetoresistance. The blockade occurs because many singly-occupied traps can only become doubly occupied in a spin-singlet configuration. Magnetic-field effects on spin mixing during transport dramatically modify the effects of this blockade and produce magnetoresistance.We calculate the quantitative effects of these traps on organic magnetoresistance from percolation theory and find a dramatic nonlinear dependence of the saturated magnetoresistance on trap density, leading to values $\sim$ 20%, within the theory's range of validity.

Entropic forces exerted on a rough wall by a grafted semiflexible polymer

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We study the entropic force due to a fluctuating semiflexible polymer that is grafted from one end and confined by a rigid and rough wall from the other end. We show how roughness of the wall modifies the entropic force. In addition to the perpendicular force that is present in the case of a flat wall, roughness of the wall adds a lateral component to the force. Both perpendicular and lateral components of the force are examined for different values of amplitude and wavelength of the roughness and at different temperatures. The lateral force is controlled by the local slope of the wall while the perpendicular force is only sensitive to the curvature of the wall. We show that for small compression, the entropic force is increased by increasing the curvature of the confining wall. In addition to the biophysical relevance, the results may also be useful in developing an AFM based experimental technique for probing the roughness of surfaces.

Matter vs vacuum oscillations at long-baseline accelerator neutrino experiments

name: Sankagiri Umasankar

Publisher: name: Zenodo
Year: 2020

description: The neutrino oscillation probabilities at the long baseline accelerator neutrino experiments are expected to be modified by matter effects. We search for evidence of such modification in the data of T2K and NOνA, by fitting the data to the hypothesis of (a) matter modified oscillations and (b) vacuum oscillations. We find that vacuum oscillations provide as good a fit to the data as matter modified oscillations. Even an extended run of these experiments, with 5 years in neutrino mode and 5 years in anti-neutrino mode, can not make a 3 σ distinction between vacuum and matter modified oscillations. DUNE, by itself, can rule out vacuum oscillations at $5~\sigma$ with one year neutrino run if the hierarchy is NH. For IH, one needs to add the data of T2K and NOvA to ten years of DUNE data to obtain $5~\sigma$ exclusion of vacuum oscillations.

description: The determination of the isotopic composition of metals has been increasingly recognized as a powerful tool to monitor metabolism in biological systems. One biologically important metal in living systems is copper, a critical enzyme cofactor, but a potent cellular toxin when unbound inside the cell. This thesis describes the development of an analytical technique to measure isotope amount ratios in biological systems. The technique was then implemented to determine how the distribution of copper isotopes changes in a system where copper metabolism has been impacted in two different ways. The first application of this technique explored how changing the expression levels of the cellular prion protein (PrPC) could affect the distribution of copper isotopes in the body. Copper isotope amount ratios were measured in the liver, kidney, red blood cells, serum, and different regions of the brain of wild type, PrPC knockout, and mice in which the copper-binding sites were mutated. The liver, kidney and brain tissue samples were enriched in 65Cu compared to the food. Characteristic changes in isotopic distribution were identified between the serum and the liver, the hippocampus, cerebral cortex, and brainstem. The second application of this technique was a careful examination of the copper isotopic fractionation in the five intestinal regions of mice. The effect of PrPC was investigated and revealed that the copper concentration was lower with inhibition or malfunction of PrPC in all regions of the gut, although only in the large intestine was any genotype dependence on the copper isotopic composition observed. Additionally, the isotopic redistribution of copper in mice with gut bacteria significantly depleted by antibiotic treatment was compared to untreated mice. A significant difference, ~1.0 ‰, in copper isotope abundances were measured in the proximal colon of antibiotic-treated mice. The changes in copper isotopic composition in the gut were associated with changes in copper transporters. Both CTR1, a protein responsible for copper import, and ATP7A, a protein responsible for copper efflux, were significantly down-regulated in antibiotic-treated mice.

description: In equilibrium, the effect of a spatially localised perturbation is typically confined around the perturbed region. Quite contrary to this, in a non-equilibrium stationary state often the entire system is affected. This appears to be a generic feature of non-equilibrium. We study such non-local response in the stationary state of a lattice gas with a shear drive at the boundary which keeps the system out of equilibrium. We show that a perturbation in the form of a localised blockage at the boundary, induces algebraically decaying density and current profile. In two examples, non-interacting particles and particles with simple exclusion, we analytically derive the power-law tail of the profiles.

description: By starting from the modified Maxwell theory coupled to gravity, the arising of geometric quantum phases in the relativistic and nonrelativistic quantum dynamics of a Dirac neutral particle from the effects of the violation of the Lorentz symmetry in the cosmic string spacetime is investigated. It is shown that the Dirac equation can be written in terms of an effective metric and a relativistic geometric phase stems from the topology of the cosmic string spacetime and the Lorentz symmetry breaking effects. Further, the nonrelativistic limit of the Dirac equation is discussed and it is shown that both Lorentz symmetry breaking effects and the topology of the defect yields a phase shift in the wave function of the nonrelativistic spin-1/2 particle.

description: We study the associated production of real (isolated) or virtual photons (with their subsequent leptonic decay) and hadronic jets in proton-proton collisions at the LHC using the $k_T$-factorization approach of QCD. The consideration is based on the off-shell quark-gluon QCD Compton scattering subprocesses. In the case of virtual photon production, the contributions from Z boson exchange as well as gamma*-Z interference with the full spin correlations are included. The transverse momentum dependent (TMD) quark and gluon densities in a proton are determined from the Kimber-Martin-Ryskin prescription or Catani-Ciafoloni-Fiorani-Marchesini (CCFM) equation. In the latter, we restricted to the case where the gluon-to-quark splitting occurs at the last evolution step and calculate the sea quark density as a convolution of the CCFM-evolved gluon distribution and the TMD gluon-to-quark splitting function. Our numerical predictions are compared with the recent experimental data taken by the ATLAS Collaboration. We discuss the theoretical uncertainties of our calculations and argue that further studies are capable of constraining the TMD parton densities in a proton.

description: This letter details the findings, considerations and recommendations of the Board of Officers that the Leon Springs Military Reservation has inadequate forage and water during the summer months to properly subsist the number of deer now present. It is believed the scarcity of water is of particular importance. That the Commanding General, or his designated representative, permit controlled hunting by military personnel located at Fort Sam Houston, and Camp Bullis. It is suggested that this hunting be in accordance with the hunting laws of the state of Texas i.e. during the period 16 November to 31 December inclusive, deer must have at least one pronged horn and a limit of not over two deer per person per season. It is also suggested that a total kill not to exceed 150 deer be set for the year 1945 and future kills should be prescribed as conditions and experience might indicate.

description: The goal of this study is to investigate the fundamental principles underlying the use of the digital twin in common industrial operations and the agri-food supply chain, as well as the development of methodologies and frameworks for the digital twin to reduce the waste of fresh produce, particularly fruits. Thus, the study began with the identification of basic concepts related to the digital twin and its advances in the agri-food supply chain. Moreover, methodologies and a general framework for implementation have been suggested based on the operating model of the Italian food bank (Banco Alimentare Campania Onlus), which includes fruit donors, the food bank, and local charity groups as supply chain actors. First, a detailed review has been performed to explore the fundamental concepts of the digital twin application in the main industrial activities, including production, predictive maintenance, and after-sales services. This is followed by a section with an analysis of existing literature on the use of digital twins in the agri-food supply chain, which has recently attracted the attention of many research institutes and companies. In this sector, digital twin could be used to monitor the real-time status of fresh produce as well as supply chain activities, although the approaches are not specified. In the third chapter, a machine learning-based digital twin technique was devised and applied to track the evolution of fruit quality changes throughout storage, and good prediction accuracy was achieved to develop product twin. The fourth part of the study has focused on the creation of a cloud analytics-based digital twin capable of efficiently reducing fruit loss at the inventory level using historical time-series data. The fifth section of the study demonstrates the possible use of digital twins for near-real-time optimization of fruit deliveries from the food bank to local charity organizations, which is also regarded to have a considerable improvement in fruit waste reduction, which is mostly driven by limited fleet size and long routes during transportation. The last section presents a general framework of a fruit supply chain digital twin model, which includes an integrated solution for monitoring fruit quality status, inventory planning, and delivery optimization. According to this research, despite a lack of common understanding of the concept, digital twin applications could enhance operational performance in many industrial sectors, including the agri-food supply chain. The proposed methods could also increase visibility in the fruit supply chain, reducing waste and meeting additional sustainability goals. [edited by Author]

description: Explicit diagrammatic calculation of evolution equations for high-twist correlation functions is a challenge already at one-loop order in QCD coupling. The main complication being quite involved mixing pattern of the so-called non-quasipartonic operators. Recently, this task was completed in the literature for twist-four nonsinglet sector. Presently, we elaborate on a particular component of renormalization corresponding to the mixing of gauge-invariant operators with QCD equations of motion. These provide an intrinsic contribution to evolution equations yielding total result in agreement with earlier computations that bypassed explicit analysis of Feynman graphs.

From fresh to saline: a comparison of zooplankton and plant communities developing under a gradient of salinity with communities developing under constant salinity levels

In Australia, many freshwater wetlands are becoming saline. Knowing which elements of a biotic community will persist as wetlands turn saline is relevant to their future management. We simulated gradual and sudden increases in salinity in outdoor mesocosms to test the hypotheses that: (1) aquatic plant and zooplankton communities exposed to a gradient of increasing salinity over time would initially resemble freshwater communities, but as the salinity increased they would resemble communities found in more saline systems; and (2) that a gradual change in salinity over 6 months influences zooplankton and plant communities in the same way as a sudden salinity change. Below 1000 mg L–1, as salinity increased gradually, communities rich in species and numbers of individuals resembled freshwater communities. However, as the salinity exceeded 1000 mg L–1, taxa were progressively lost and communities became less diverse. When salinities exceeded 3000 mg L–1 the diversity decreased rapidly and few taxa remained at 5000 mg L–1. Both sudden and gradual increases in salinity induced similar decreases in diversity. We predict that as natural wetlands become more saline, few freshwater biota will survive once the salinity exceeds 5000 mg L–1. In the long term, such salinised wetlands would need to be recolonised by salt-tolerant taxa for a functional wetland to persist.
