Quantum Landau-Lifshitz model at four loops: 1/J and 1/J^2 corrections to BMN energies
Creators: name: Tirziu, A.
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In a previous paper (hep-th/0510080) the effective Landau-Lifshitz (LL) Lagrangians in the SU(2) sector coming from string theory and gauge theory have been found to three loops in the effective expansion parameter $\tildeλ=λ/J^2$. In this paper we continue this study and find the effective Landau-Lifshitz Lagrangians to four loops. We extend to four-loops $\tildeλ^4$ the computations of 1/J and $1/J^2$ corrections to BMN energies done in hep-th/0510080 to three-loops. We compare these corrections obtained from quantum ``gauge-theory'' LL action with the corrections obtained from the conjectured Bethe ansatz for the long range spin chain representing perturbative {large $N$} $\NN=4$ Super Yang-Mills in the SU(2) sector and find perfect matching to four loops $\tildeλ^4$. We compare also the 1/J and $1/J^2$ corrections obtained from quantum ``string-theory'' LL action with those obtained from the "quantum string" Bethe ansatz and again find perfect matching to four-loops.

description: Experiments of water wicking in 1D silicon-dioxide nanochannels of heights 59 nm, 87 nm, 124 nm and 1015 nm are used to estimate the disjoining pressure of water which was found to be as high as ~1.5 MPa while exponentially decreasing with increasing channel height. Such a relation resulting from curve fitting of experimentally-derived data was implemented and validated in computational fluid dynamics. This methodology integrates experimental nanoscale physics into continuum simulations thus enabling the numerical study of various phenomena where disjoining pressure plays an important role.

description: A new alternate method for evaluating linear response theory is formally developed, and results are presented. This method involves the time-evolution of the system using TDHF and is constructed directly on top of a static Hartree-Fock calculation. By Fourier transforming the time-dependent result the response function and the total probability amplitude are extracted. This method allows for a coherent description of static properties of nuclei, such as binding energies and deformations, while also providing a method for calculating collective modes and reaction rates. A full 3-D Cartesian Basis-Spline collocation representation is used with several Skyrme interactions. Sample results are presented for the giant multipole resonances of 16O, 40Ca, and 32S and compared to other calculations.

description: Scattered light from the Earth and Moon can significantly impact the background levels in TESS (Transiting Exoplanet Survey Satellite) full frame images (FFIs), hindering the search for transiting exoplanets and other astronomical phenomena. We present a novel approach to model and remove scattered light at the image level using deep learning. We have developed a conditional diffusion model that accurately captures the scattered light patterns in FFIs probabilistically, using only the angles and distances of the Earth and Moon with respect to the TESS cameras. The model learns the complex, dynamic patterns of scattered light and produces corrected FFIs along with uncertainties. This deep learning approach opens up new avenues for scattered light and systematics correction in present and future space based surveys.

description: Dual-energy imaging is a clinically well-established technique that offers several advantages over conventional X-ray imaging. By performing measurements with two distinct X-ray spectra, differences in energy-dependent attenuation are exploited to obtain material-specific information. This information is used in various imaging applications to improve clinical diagnosis. In recent years, grating-based X-ray dark-field imaging has received increasing attention in the imaging community. The X-ray dark-field signal originates from ultra small-angle scattering within an object and thus provides information about the microstructure far below the spatial resolution of the imaging system. This property has led to a number of promising future imaging applications that are currently being investigated. However, different microstructures can hardly be distinguished with current X-ray dark-field imaging techniques, since the detected dark-field signal only represents the total amount of ultra small-angle scattering. To overcome these limitations, we present a novel concept called dual-energy X-ray dark-field material decomposition, which transfers the basic material decomposition approach from attenuation-based dual-energy imaging to the dark-field imaging modality. We develop a physical model and algorithms for dual-energy dark-field material decomposition and evaluate the proposed concept in experimental measurements. Our results suggest that by sampling the energy-dependent dark-field signal with two different X-ray spectra, a decomposition into two different microstructured materials is possible. Similar to dual-energy imaging, the additional microstructure-specific information could be useful for clinical diagnosis.

description: The energy-economic impact forecasting system presented here is a modular approach to both economic modeling and information systems development. A set of eleven modules--market, investment, demand, production, (input-output), employment, value added, labor force, population, household, fiscal, and ecologic--provides the data base and programming routines for simulating the state (or a substate regional) economy. An additional set of government function modules, including energy and environmental management, provides an auxiliary data base and forecasts for state and local government agencies. This series of data modules and related computer programs, locally called SIMLAB, is organized as a readily accessible regional impact simulation system.

description: Optimal Control Theory is a powerful mathematical tool, which has known a rapid development since the 1950s, mainly for engineering applications. More recently, it has become a widely used method to improve process performance in quantum technologies by means of highly efficient control of quantum dynamics. This tutorial aims at providing an introduction to key concepts of optimal control theory which is accessible to physicists and engineers working in quantum control or in related fields. The different mathematical results are introduced intuitively, before being rigorously stated. This tutorial describes modern aspects of optimal control theory, with a particular focus on the Pontryagin Maximum Principle, which is the main tool for determining open-loop control laws without experimental feedback. The different steps to solve an optimal control problem are discussed, before moving on to more advanced topics such as the existence of optimal solutions or the definition of the different types of extremals, namely normal, abnormal, and singular. The tutorial covers various quantum control issues and describes their mathematical formulation suitable for optimal control. The connection between the Pontryagin Maximum Principle and gradient-based optimization algorithms used for high-dimensional quantum systems is described. The optimal solution of different low-dimensional quantum systems is presented in detail, illustrating how the mathematical tools are applied in a practical way.

description: We describe early success in the evolution of binary black hole spacetimes with a numerical code based on a generalization of harmonic coordinates. Indications are that with sufficient resolution this scheme is capable of evolving binary systems for enough time to extract information about the orbit, merger and gravitational waves emitted during the event. As an example we show results from the evolution of a binary composed of two equal mass, non-spinning black holes, through a single plunge-orbit, merger and ring down. The resultant black hole is estimated to be a Kerr black hole with angular momentum parameter a~0.70. At present, lack of resolution far from the binary prevents an accurate estimate of the energy emitted, though a rough calculation suggests on the order of 5% of the initial rest mass of the system is radiated as gravitational waves during the final orbit and ringdown.

description: It's became clear that Land is not only a basic factor of production, it also has a number of specific features. Against this background, it has long been recognized that clarifying property rights to land can enhance economic growth through a number of channels: - The mean macroeconomic view is that the land has to be provided and used by government and non-governmental institutions, local community and the private sector for a wide range of purposes. Enforced property rights and security will also increase incentives for land-demand related to investment and thus overall economic output. In that way, the enforcement of property rights to land will provide incentive for good natural resources management - Efficient mechanisms for enforcing the land access and property rights exchange or transfer, are a precondition to promote the land productivity, increase agriculture output and can be used for credit as collateral in the transaction. - Well-defined land rights are an indispensable basis to increase the tax-payees, important mechanism to increase government revenue.

description: In this article, we present a measurement of flow rate, yield and effusion time of a $^{23}$Ne production and transport system. We used an accelerator-driven Li(d,n) neutron source to produce neutrons up to 20 MeV. The radioactive atoms were produced by a $^{23}$Na(n,p) reaction at a NaCl target. Later, the atoms were diffused out from the NaCl crystals and effused from the production chamber via a 10 m hose to a measurement cell and their decay products were detected using high purity germanium (HPGe) and plastic scintillator detectors. The resulting flow rate was $6.9\pm0.5\cdot 10^4\sfrac{atoms}{sec}$ and the total yield was $3.2\pm0.4\cdot10^{-9}\sfrac{atoms}{deuteron}$. We summarize our methods and estimates of efficiencies, rates of production and effusion.
Forecasting Indian monsoon rainfall using regional circulation fields as predictors : an ensemble neural network approach
Creators: name: Cannon, Alex Jason
Publisher: name: University of British Columbia
Year: 2009

description: Pre-monsoon principal components of circulation fields covering the South Asian subcontinent were used as predictors for all-India summer monsoon rainfall (AISMR) during the period 1958- 1998. Predictive skill and stationarity of non-linear ensemble neural network and linear multiple regression model relationships were assessed using a Monte Carlo-based resampling procedure. Monsoon precursor signals represented by the PCs were investigated using a model sensitivity analysis and comparisons were made with recent observational and general circulation modelling studies. Results suggest the presence of coherent, stable predictive relationships between AISMR and the SLP field during November (median r=0.5, p=0.05), as well as between AISMR and the 200 hPa geopotential height field during May (median r=0.67, p < 0.005). The latter relationship was essentially linear, and appears to be related to the winter-summer transition between a flow regime dominated by the subtropical westerly jet stream to one dominated by the tropical easterly jet stream, as well as to changes in strength and position of the upper tropospheric Tibetan anticyclone. The former relationship was nonlinear, appearing in essentially the same form at the 850 hPa level (median r=0.37, p=0.06). Possibly related to anomalous SSTs in the Arabian Sea, further work is required to determine physical mechanisms responsible for predictive skill at this lead-time. Weaker relationships were observed between summer monsoon rainfall and PCs of the SLP field during May (median r=0.47, p=0.10) and PCs of the 850 hPa geopotential height field during January (median r=0.40, p=0.10). May SLP-rainfall relationships were not significant until the early 1970s but remained relatively stable for the remainder of the record. Spatially, maximum correlations and model sensitivities were centred over northwest India and Pakistan, suggesting a link with pre-monsoon heating and development of the heat low over Pakistan. Relationships between January 850 hPa geopotential heights and rainfall were nonstationary, only showing significant correlations during portions of the record. Significant differences in skill between neural network and multiple linear regression models were present at this level and lead-time, consistent with indications of nonlinearity and interactions between inputs suggested by the sensitivity analysis. Further work is required to determine whether these relationships have physical meaning or whether they are simply a statistical artifact.

description: The paper discusses the linkages between the "globalization" of agricultural markets over recent decades and the decisions being made by individual farmers and ranchers in the United States. It is noted that technological advances lead to globalization of agricultural commodity markets and profit pressures. The continuing profit squeeze in agricultural production is having a significant effect on the cropping choices of America's farmers. When possible, acreage is being shifted out of low-revenue-generating crops and into higher-revenue-generating crops. This shift makes crop portfolios more risky over time, thus encouraging farmers to consider diversifying out of agriculture.

description: It is shown that the group of generalized Lorentz transformations serves as relativistic symmetry group of a flat Finslerian event space. Being the generalization of Minkowski space, the Finslerian event space arises from the spontaneous breaking of initial gauge symmetry and from the formation of anisotropic fermion-antifermion condensate. The principle of generalized Lorentz invariance enables exact taking into account the influence of condensate on the dynamics of fundamental fields. In particular, the corresponding generalized Dirac equation turns out to be nonlinear. We have found two noncompact subgroups of the group of generalized Lorentz symmetry and their geometric invariants. These subgroups play a key role in constructing exact solutions of such equation.

description: We demonstrate terahertz time-domain spectroscopy (THz-TDS) to be an accurate, rapid and scalable method to probe the interaction-induced Fermi velocity renormalization νF^* of charge carriers in graphene. This allows the quantitative extraction of all electrical parameters (DC conductivity σDC, carrier density n, and carrier mobility μ) of large-scale graphene films placed on arbitrary substrates via THz-TDS. Particularly relevant are substrates with low relative permittivity (< 5) such as polymeric films, where notable renormalization effects are observed even at relatively large carrier densities (> 10^12 cm-2, Fermi level > 0.1 eV). From an application point of view, the ability to rapidly and non-destructively quantify and map the electrical (σDC, n, μ) and electronic (νF^* ) properties of large-scale graphene on generic substrates is key to utilize this material in applications such as metrology, flexible electronics as well as to monitor graphene transfers using polymers as handling layers.

description: We present molecular dynamics simulations of aggregation kinetics in a colloidal suspension modeled as a highly asymmetric binary mixture. Starting from a configuration with largely uncorrelated colloidal particles the system relaxes by coagulation-fragmentation dynamics to a structured state of low-dimensionality clusters with an exponential size distribution. The results show that short-range repulsive interactions alone can give rise to so-called cluster phases. For the present model and probably other, more common colloids, the observed clusters appear to be equilibrium phase fluctuations induced by the entropic inter-colloidal attractions.

description: Chandra observations toward the nearby molecular cloud MBM12 show unexpectedly strong and nearly equal foreground O VIII and O VII emission. As the observed portion of MBM12 is optically thick at these energies, the emission lines must be formed nearby, coming either from the Local Bubble (LB) or charge exchange with ions from the Sun. Equilibrium models for the LB predict stronger O VII than O VIII, so these results suggest that the LB is far from equilibrium or a substantial portion of O VIII is from another source, such as charge exchange within the Solar system. Despite the likely contamination, we can combine our results with other EUV and X-ray observations to reject LB models which posit a cool recombining plasma as the source of LB X-rays.

description: Correlation functions of most composite operators decay exponentially with time at non-zero temperature, even in free field theories. This insight was recently codified in an OTH (operator thermalisation hypothesis). We reconsider an early example, with large $N$ free fields subjected to a singlet constraint. This study in dimensions $d>2$ motivates technical modifications of the original OTH to allow for generalised free fields. Furthermore, Huygens' principle, valid for wave equations only in even dimensions, leads to differences in thermalisation. It works straightforwardly when Huygens' principle applies, but thermalisation is more elusive if it does not apply. Instead, in odd dimensions we find a link to resurgence theory by noting that exponential relaxation is analogous to non-perturbative corrections to an asymptotic perturbation expansion. Without applying the power of resurgence technology we still find support for thermalisation in odd dimensions, although these arguments are incomplete.

description: Clinical cases of BVD are either enteric or reproductive problems. The enteric form causes economic loss in animals that die of acute or chronic diarrhea. The reproductive form may contribute to losses by causing abortions, repeat breeders or the birth of malformed calves usually following a BVD infection in non-immune heifers. The magnitude of the economic losses due to the reproductive form has not been accurately determined and this should be done so the cost of the disease can be compared to the cost of control.

description: In recent years, dynamical quantum phase transitions (DQPTs) have emerged as a useful theoretical concept to characterize nonequilibrium states of quantum matter. DQPTs are marked by singular behavior in an \textit{effective free energy} $λ(t)$, which, however, is a global measure, making its experimental or theoretical detection challenging in general. We introduce two local measures for the detection of DQPTs with the advantage of requiring fewer resources than the full effective free energy. The first, called the \textit{real-local} effective free energy $λ_M(t)$, is defined in real space and is therefore suitable for systems where locally resolved measurements are directly accessible such as in quantum-simulator experiments involving Rydberg atoms or trapped ions. We test $λ_M(t)$ in Ising chains with nearest-neighbor and power-law interactions, and find that this measure allows extraction of the universal critical behavior of DQPTs. The second measure we introduce is the \textit{momentum-local} effective free energy $λ_k(t)$, which is targeted at systems where momentum-resolved quantities are more naturally accessible, such as through time-of-flight measurements in ultracold atoms. We benchmark $λ_k(t)$ for the Kitaev chain, a paradigmatic system for topological quantum matter, in the presence of weak interactions. Our introduced local measures for effective free energies can further facilitate the detection of DQPTs in modern quantum-simulator experiments.

description: It has been proposed recently a new incremental modelling to describe the mechanics of soil. It is based on two parameters called the pseudo Young modulus E=1/Co and the pseudo Poisson coefficient n, which both evolve during compression. Evolution of n is known since it shall fit the Rowe's law of dilatancy, but Co has to be evaluated from experiment. In this paper we proposed a way to evaluate the Co variation from other mechanical modelling. The way cyclic behaviour of drained sample can be modelled is also described.

Resistant Salmonellosis in Southern Alberta Feedlots
Creators: name: Harries, W. N.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1980

description: Death losses were normally between I% and 2% but with the advent of salmonellosis, losses increased to between 2% and 2½%. In addition there were increases in cattle prices, in interest rates and in feed costs. Veterinary services and drugs became expensive and many treated animals developed chronic sicknesses. Finally, there was concern over the possibility of investigation by public health authorities. Losses continued at a lower level throughout the summer and fall of 1979 but rose to a second peak during the winter. Losses then gradually decreased in the spring of 1980 and finally stopped during midsummer.

Clinical Management of Early Fetal Death
Creators: name: Woelffer, Elmer
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1980

description: Our program was this, if we found that a cow had early embryonic death we would start the progesterone treatment on the fourth day after service. That is we gave l0cc (or 500mg) intramuscularly and then we repeated it every IO days. Now if the embryonic death occurred later, let's say after 50, 60 or 90 days, then we would wait until the cow passed one heat period and start the progesterone injection on the 27th or 28th day and we tried to estimate the time that the embryo died and from that date we would go beyond 60 or 70 days and then we would stop.

description: We investigate the symmetry properties of a pair of Ermakov equations. The system is superintegrable and yet possesses only three Lie point symmetries with the algebra sl(2,R). The number of point symmetries is insufficient and the algebra unsuitable for the complete specification of the system. We use the method of reduction of order to reduce the nonlinear fourth-order system to a third-order system comprising a linear second-order equation and a conservation law. We obtain the representation of the complete symmetry group from this system. Four of the required symmetries are nonlocal and the algebra is the direct sum of a one-dimensional Abelian algebra with the semidirect sum of a two-dimensional solvable algebra with a two-dimensional Abelian algebra. The problem illustrates the difficulties which can arise in very elementary systems. Our treatment demonstrates the existence of possible routes to overcome these problems in a systematic fashion.

Existence and uniqueness of strong solutions for the system of interaction between a compressible Navier-Stokes-Fourier fluid and a damped plate equation

description: The article is devoted to the mathematical analysis of a fluid-structure interaction system where the fluid is compressible and heat conducting and where the structure is deformable and located on a part of the boundary of the fluid domain. The fluid motion is modeled by the compressible Navier-Stokes-Fourier system and the structure displacement is described by a structurally damped plate equation. Our main results are the existence of strong solutions in an $L^p-L^q$ setting for small time or for small data. Through a change of variables and a fixed point argument, the proof of the main results is mainly based on the maximal regularity property of the corresponding linear systems. For small time existence, this property is obtained by decoupling the linear system into several standard linear systems whereas for global existence and for small data, the maximal regularity property is proved by showing that the corresponding linear coupled {\em fluid-structure} operator is $\mathcal{R}-$sectorial.

Bypassing the Rumen with Lipids and Protein
Creators: name: Macleod, G. K.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1980

description: One of the most significant developments in ruminant nutrition in recent years has been that of learning to manipulate diets for more effective digestion and production. One of these techniques has been to bypass the rumen when digestion of protein or lipid is not desirable at this site. By bypass we mean that proteins and/or lipids pass through the reticlo-rumen without being affected by rumen microbes and without altering normal bio-chemical processes in the rumen.

Non-linear screening effects in high energy hadronic interactions
Creators: name: Ostapchenko, S.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Non-linear effects in hadronic interactions are treated by means of enhanced pomeron diagrams, assuming that pomeron-pomeron coupling is dominated by soft partonic processes. It is shown that the approach allows to resolve a seeming contradiction between realistic parton momentum distributions, measured in deep inelastic scattering experiments, and the energy behavior of total proton-proton cross section. Also a general consistency with both ``soft'' and ``hard'' diffraction data is demonstrated. An important feature of the proposed scheme is that the contribution of semi-hard processes to the interaction eikonal contains a significant non-factorizable part. On the other hand, the approach preserves the QCD factorization picture for inclusive high p_t jet production.

description: The gender gap is a significant concern facing the software industry as the development becomes more geographically distributed. Widely shared reports indicate that gender differences may be specific to each region. However, how complete can these reports be with little to no research reflective of the Open Source Software (OSS) process and communities software is now commonly developed in? Our study presents a multi-region geographical analysis of gender inclusion on GitHub. This mixed-methods approach includes quantitatively investigating differences in gender inclusion in projects across geographic regions and investigate these trends over time using data from contributions to 21,456 project repositories. We also qualitatively understand the unique experiences of developers contributing to these projects through a survey that is strategically targeted to developers in various regions worldwide. Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise. From these findings, we derive and present implications for tools that can foster inclusion in open source software communities and empower contributions from everyone, everywhere.

Year: 1980

description: The experience of dairymen working with today's high nutrient content, low fibre feeds, and research involving the dry cow, have made it clear that prepartum management and feeding have a major impact on health at parturition and early lactation productivity. When inadequate management is applied during the dry period, the incidence of post calving disorders, including retained placenta, metritis, milk fever, mastitis, ketosis, udder edema, and displaced abomasum may be significantly increased.

description: A systematic procedure is developed for constructing fermion systems in discrete space-time which have a given outer symmetry. The construction is illustrated by simple examples. For the symmetric group, we derive constraints for the number of particles. In the physically interesting case of many particles and even more space-time points, this result shows that the permutation symmetry of discrete space-time is always spontaneously broken by the fermionic projector.

description: High Energy Physics (HEP) experiments rely on the networks as one of the critical parts of their infrastructure both within the participating laboratories and sites as well as globally to interconnect the sites, data centers and experiments instrumentation. Network virtualisation and programmable networks are two key enablers that facilitate agile, fast and more economical network infrastructures as well as service development, deployment and provisioning.Adoption of these technologies by HEP sites and experiments will allow them to design more scalable and robust networks while decreasing the overall cost and improving the effectiveness of the resource utilization.The primary challenge we currently face is ensuring that WLCG and its constituent collaborations will have the networking capabilities required to most effectively exploit LHC data for the lifetime of the LHC. In this paper we provide a high level summary of the HEPiX NFV Working Group report that explored some of the novel network capabilities that could potentially be deployment in time for HL-LHC.

description: New model equations are derived for dynamics of self-aggregation of finite-size particles. Differences from standard Debye-Huckel and Keller-Segel models are: the mobility of particles depends on the configuration of their neighbors and linear diffusion acts on locally-averaged particle density. The evolution of collapsed states in these models reduces exactly to finite-dimensional dynamics of interacting particle clumps. Simulations show these collapsed (clumped) states emerge from smooth initial conditions, even in one spatial dimension.
