description: We consider large-scale Markov decision processes with an unknown cost function and address the problem of learning a policy from a finite set of expert demonstrations. We assume that the learner is not allowed to interact with the expert and has no access to reinforcement signal of any kind. Existing inverse reinforcement learning methods come with strong theoretical guarantees, but are computationally expensive, while state-of-the-art policy optimization algorithms achieve significant empirical success, but are hampered by limited theoretical understanding. To bridge the gap between theory and practice, we introduce a novel bilinear saddle-point framework using Lagrangian duality. The proposed primal-dual viewpoint allows us to develop a model-free provably efficient algorithm through the lens of stochastic convex optimization. The method enjoys the advantages of simplicity of implementation, low memory requirements, and computational and sample complexities independent of the number of states. We further present an equivalent no-regret online-learning interpretation.

description: In superconducting ferromagnets for which the Curie temperature $T_{m}$ exceeds the superconducting transition temperature $T_{c}$, it was suggested that ferromagnetic spin fluctuations could lead to superconductivity with p-wave spin triplet Cooper pairing. Using the Stoner model of itinerant ferromagnetism, we study the feedback effect of the p-wave superconductivity on the ferromagnetism. Below $T_{c}$, the ferromagnetism is enhanced by the p-wave superconductivity. At zero temperature, the critical Stoner value for itinerant ferromagnetism is reduced by the strength of the p-wave pairing potential, and the magnetization increases correspondingly. More important, our results suggest that once Stoner ferromagnetism is established, $T_m$ is unlikely to ever be below $T_c$. For strong and weak ferromagnetism, three and two peaks in the temperature dependence of the specific heat are respectively predicted, the upper peak in the latter case corresponding to a first-order transition.

description: A Unified Emergent Field Theory: Space, Time, Mass, Light, and Quantization from a Single Scalar Field

We present a numerical and theoretical framework in which space, time, mass, light, and quantization emerge from the dynamics of a single scalar field ϕ(x,t)\phi(x,t)ϕ(x,t). Starting from near-zero initial conditions, the field evolves under a nonlinear self-interaction potential to self-organize into coherent structures. We demonstrate that spatial geometry arises from the field’s magnitude, mass-like energy concentrations emerge from localized φ compression, time is defined by recursive zero-crossings, and quantization appears naturally in the field’s spectral modes. A gravitational analog of Planck’s constant, ℏg\hbar_gℏg, is extracted numerically. Light emerges as traveling φ wave packets with minimal dispersion. This model suggests a unified physical substrate from which both classical and quantum phenomena—and possibly time-aware structure—can arise.

This framework may offer a foundation for emergent spacetime, informational geometry, and recursive systems such as biological memory and consciousness.

description: Optical absorption measurements are used to probe the spin polarization in the integer and fractional quantum Hall effect regimes. The system is fully spin polarized only at filling factor $ν=1$ and at very low temperatures($\sim40$ mK). A small change in filling factor ($δν\approx\pm0.01$) leads to a significant depolarization. This suggests that the itinerant quantum Hall ferromagnet at $ν=1$ is surprisingly fragile against increasing temperature, or against small changes in filling factor.

description: In this work, we develop a design methodology to generate spectrally pure photon pairs in asymmetric heterogeneously coupled waveguides by spontaneous parametric down-conversion. Mode coupling in a system of waveguides is used to directly tailor the group velocity of a supermode to achieve group velocity matching (GVM) that is otherwise not allowed by material dispersion. Design examples based on thin film lithium niobate waveguides are provided, demonstrating high spectral purity and temperature tunability. This approach is a versatile strategy applicable to waveguides of different materials and structures, allowing more versatility in single-photon source designs.

Marginal capability lands of the Chilcotin

Publisher: name: University of British Columbia
Year: 2010

description: Capability inventory surveys have been conducted in the province for several years. Inherent in this program is the collection of baseline data on the physical environment of the area. The capability information (CLI) is valuable for land resource planning, especially in areas where little resource development has occurred. The mechanism of collection and the utility of capability data were examined in the Chilcotin area of British Columbia in an attempt to develop a land use plan. A reconnaissance terrain survey was conducted. The survey relied heavily on air photo interpretation and used landforms as the physical base. Five terrain types, based on soil and other landscape characteristics were identified and characterized in the study area. Detailed ground information was collected from a representative site on each terrain type. The information was used to characterize the terrain type and make resource capability interpretations for agriculture, forestry, wildlife and recreation. The capability of these resource sectors were evaluated for the purpose of preparing a land use plan for the terrain types within the area. The plan identified integrated resource use as the optimal type of resource development. The study provides a guide to integrated management of the area. Resource conflicts were identified and supplemental information requirements were noted.

description: At the LHC Multiple Parton Interactions will represent an important feature of the minimum bias and of the underlying event and will give important contributions in many channels of interest for the search of new physics. Different numbers of multiple collision may contribute to the production of a given final state and one should expect important interference effects in the regime where different contributions have similar rates. We show, on the contrary, that, once multiple parton interactions are identified by their different topologies, terms with different numbers of multiple parton interactions do not interfere in the final cross section.

description: Decentralised machine learning has recently been proposed as a potential solution to the security issues of the canonical federated learning approach. In this paper, we propose a decentralised and collaborative machine learning framework specially oriented to resource-constrained devices, usual in IoT deployments. With this aim we propose the following construction blocks. First, an incremental learning algorithm based on prototypes that was specifically implemented to work in low-performance computing elements. Second, two random-based protocols to exchange the local models among the computing elements in the network. Finally, two algorithmics approaches for prediction and prototype creation. This proposal was compared to a typical centralized incremental learning approach in terms of accuracy, training time and robustness with very promising results.

description: We show that in (anomalous) U(1) gauge theories with the Fayet-Iliopoulos (FI) term and with generic interactions there are meta-stable vacua in which supersymmetry (SUSY) is spontaneously broken even without U(1)_R symmetry and various hierarchical structures, for example, Yukawa hierarchy, can be explained by the smallness of the FI parameter. When we introduce generic interactions, i.e., all interactions including higher dimensional interactions which are allowed by the symmetry of the theory with O(1) coefficients, various scales can be determined by the symmetry (U(1) charges of the introduced fields). We examine how to determine the various scales, the vacuum expectation values (VEVs), and the scales of F-term and of D-term. Moreover, we propose a new scenario for the stabilization of the moduli in the SUSY breaking models.

description: In this paper, we make the first benchmark effort to elaborate on the superiority of using RAW images in the low light enhancement and develop a novel alternative route to utilize RAW images in a more flexible and practical way. Inspired by a full consideration on the typical image processing pipeline, we are inspired to develop a new evaluation framework, Factorized Enhancement Model (FEM), which decomposes the properties of RAW images into measurable factors and provides a tool for exploring how properties of RAW images affect the enhancement performance empirically. The empirical benchmark results show that the Linearity of data and Exposure Time recorded in meta-data play the most critical role, which brings distinct performance gains in various measures over the approaches taking the sRGB images as input. With the insights obtained from the benchmark results in mind, a RAW-guiding Exposure Enhancement Network (REENet) is developed, which makes trade-offs between the advantages and inaccessibility of RAW images in real applications in a way of using RAW images only in the training phase. REENet projects sRGB images into linear RAW domains to apply constraints with corresponding RAW images to reduce the difficulty of modeling training. After that, in the testing phase, our REENet does not rely on RAW images. Experimental results demonstrate not only the superiority of REENet to state-of-the-art sRGB-based methods and but also the effectiveness of the RAW guidance and all components.

We study a model of holographic QCD in the five dimensional AdS background with a hard-wall cutoff. Both 5D SU(2) and U(3) flavor gauge symmetries are considered for the neutral pion, eta and eta' contributions to the hadronic corrections. We find the total light-by-light contributions of pseudo scalars to the muon anomalous magnetic moment, a_mu=10.7 x 10^(-10), which is consistent with previous estimates, based on other approaches.

description: Magnetic skyrmions hold great promise for realizing compact and stable memory devices that can be manipulated at very low energy costs via electronic current densities. In this work, we extend a recently introduced method to describe classical skyrmion textures coupled to dynamical itinerant electrons. In this scheme, the electron dynamics is described via nonequilibrium Green's functions (NEGF) within the generalized Kadanoff-Baym ansatz, and the classical spins are treated via the Landau-Lifshitz-Gilbert equation. The framework is here extended to open systems, by the introduction of a non-interacting approximation to the collision integral of NEGF. This, in turn, allows us to perform computations of the real-time response of skyrmions to electronic currents in large quantum systems coupled to electronic reservoirs, which exhibit a linear scaling in the number of time steps. We use this approach to investigate how electronic spin currents and dilute spin disorder affects skyrmion transport and the skyrmion Hall drift. Our results show that the skyrmion dynamics is sensitive to the specific form of spin disorder, such that different disorder configurations leads to qualitatively different skyrmion trajectories for the same applied bias. This sensitivity arises from the local spin dynamics around the magnetic impurities, a feature that is expected not to be well captured by phenomenological or spin-only descriptions. At the same time, our findings illustrate the potential of engineering microscopic impurity patterns to steer skyrmion trajectories.

Application of chromatographic and spectroscopic techniques in the evaluation of the lipid fraction of animal products
Creators: name: Ferioli, Federico <1976>
Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: AGR/15 Scienze e tecnologie alimentari

description: Lipolysis and oxidation of lipids in foods are the major biochemical and chemical processes that cause food quality deterioration, leading to the characteristic, unpalatable
odour and flavour called rancidity. In addition to unpalatability, rancidity may give rise to toxic levels of certain compounds like aldehydes, hydroperoxides, epoxides and cholesterol oxidation products. In this PhD study chromatographic and spectroscopic techniques were employed to determine the degree of rancidity in different animal products and its relationship with technological parameters like feeding fat sources, packaging, processing and storage
conditions. To achieve this goal capillary gas chromatography (CGC) was employed not only to determine the fatty acids profile but also, after solid phase extraction, the amount of free fatty acids (FFA), diglycerides (DG), sterols (cholesterol and phytosterols) and cholesterol oxidation products (COPs). To determine hydroperoxides, primary products of oxidation and quantify secondary products UV/VIS absorbance spectroscopy was applied. Most of the foods analysed in this study were meat products. In actual fact, lipid oxidation is a major deterioration reaction in meat and meat products and results in adverse changes in the colour, flavour and texture of meat. The development of rancidity has long recognized as a serious problem during meat handling, storage and processing. On a dairy product, a vegetal cream, a study of lipid fraction and development of rancidity during storage was carried out to evaluate its shelf-life and some nutritional features life saturated/unsaturated fatty acids ratio and phytosterols content. Then, according to the interest that has been growing around functional food in the last years, a new electrophoretic method was optimized and compared with HPLC to check the quality of a beehive product like royal jelly. This manuscript reports the main results obtained in the five activities briefly summarized as follows: 1) comparison between HPLC and a new electrophoretic method in the evaluation of authenticity of royal jelly; 2) study of the lipid fraction of a vegetal cream under different storage conditions; 3) study of lipid oxidation in minced beef during storage under a modified atmosphere packaging, before and after cooking; 4) evaluation of the influence of dietary fat and processing on the lipid fraction of chicken patties; 5) study of the lipid fraction of typical Italian and Spanish pork dry sausages and cured hams.

description: Markov categories, having tensors with copying and discarding, provide a setting for categorical probability. This paper uses finite colimits and what we call uniform states in such Markov categories to define a (fixed size) multiset functor, with basic operations for sums and zips of multisets, and a graded monad structure. Multisets can be used to represent both urns filled with coloured balls and also draws of multiple balls from such urns. The main contribution of this paper is the abstract definition of multinomial and hypergeometric distributions on multisets, as draws. It is shown that these operations interact appropriately with various operations on multisets.

Year: 2009
Subjects: subject: Classical Physics (physics.class-ph)

description: This paper proposes a new method, in the frequency domain, to define absorbing boundary conditions for general two-dimensional problems. The main feature of the method is that it can obtain boundary conditions from the discretized equations without much knowledge of the analytical behavior of the solutions and is thus very general. It is based on the computation of waves in periodic structures and needs the dynamic stiffness matrix of only one period in the medium which can be obtained by standard finite element software. Boundary conditions at various orders of accuracy can be obtained in a simple way. This is then applied to study some examples for which analytical or numerical results are available. Good agreements between the present results and analytical solutions allow to check the efficiency and the accuracy of the proposed method.

description: The concept of updating (or conditioning or revising) a probability distribution is fundamental in (machine) learning and in predictive coding theory. The two main approaches for doing so are called Pearl's rule and Jeffrey's rule. Here we make, for the first time, mathematically precise what distinguishes them: Pearl's rule increases validity (expected value) and Jeffrey's rule decreases (Kullback-Leibler) divergence. This forms an instance of a more general distinction between learning from what's right and learning from what's wrong. The difference between these two approaches is illustrated in a mock cognitive scenario.

Its validity spans a wide invariant mass range starting from pion production threshold. This model focuses on the low invariant mass region which is probed in few-GeV neutrino interactions and is of particular importance to neutrino oscillation experiments using accelerator and atmospheric fluxes. It exhibits reasonable agreement with a wide variety of experimental data. We also describe measurements that can be made in upcoming experiments that can improve modeling in areas where uncertainties are currently large.

description: We investigate the structure of the $D_{s1}(2460,2536) (J^P=1^+)$ mesons via analyzing the semileptonic $B_{c}\to D_{s1}l^+l^-$, $l=τ, μ, e$ and $B_{c}\to D_{s1}ν\barν$ transitions in the framework of the three--point QCD sum rules. We consider the $D_{s1}$ meson in two ways, the pure $|c\bar{s}>$ state and then as a mixture of two $|^3P_1>$ and $|^1P_1>$ states. Such type rare transitions take place at loop level by electroweak penguin and weak box diagrams in the standard model via the flavor changing neutral current transition of $b \to s$. The relevant form factors are calculated taking into account the gluon condensate contributions. These form factors are numerically obtained for $|c\bar s>$ case and plotted in terms of the unknown mixing angle $θ_s$, when the $D_{s1}$ meson are considered as mixture of two $|^3P_1>$ and $|^1P_1>$ states. The obtained results for the form factors are used to evaluate the decay rates and branching ratios. Any future experimental measurement on these form factors as well as decay rates and branching fractions and their comparison with the obtained results in the present work can give considerable information about the structure of this meson and the mixing angle $θ_s$.

This model has new and interesting features. %, specially concerning the energy exchange between the matter fields and the curvature. However, as any modified gravity theories, these may give origin to anomalies which might turn the theory physically meaningless. In this respect, one undertakes a study on the energy conditions and the Dolgov-Kawasaki criterion specific of this new model.

description: We consider a bag (multiset) monad on the category of standard Borel spaces, and show that it gives a free measurable commutative monoid. Firstly, we show that a recent measurability result for probabilistic database queries (Grohe and Lindner, ICDT 2020) follows quickly from the fact that queries can be expressed in monad-based terms. We also extend this measurability result to a fuller query language. Secondly, we discuss a distributive law between probability and bag monads, and we illustrate that this is useful for generating probabilistic databases.

The scheme is applicable to the cases in which there exits a local predicate for each node, such that global consistency is implied by the union of the local predicates. We demonstrate our scheme over the token circulation algorithm of Herman and the recent constant time Byzantine self-stabilizing clock synchronization algorithm by Ben-Or, Dolev and Hoch. The application of our scheme results in the first constant time Byzantine self-stabilizing clock synchronization algorithm that uses a bounded number of random bits.

description: With the goal of studying ML along the RGB, mid-IR observations 
of a carefully selected sample of 17 Galactic globular
clusters (GGCs) with different metallicity and horizontal branch
(HB) morphology have been secured with IRAC on board Spitzer: 
a global sample counting about 8000 giant has been obtained. 
Suitable complementary photometry in the optical and near-IR 
has been also secured in order to properly characterize 
the stellar counterparts to the Spitzer sources and their photospheric parameters.
Stars with color (i.e. dust) excess have been identified, their likely 
circumstellar emission quantified and modelled, and empirical estimates of mass 
loss rates and timescales obtained.
We find that mass loss rates increases with increasing 
stellar luminosity and decreasing metallicity.
For a given luminosity, we find that ML rates are 
systematically higher than the prediction 
by extrapolating the Reimers law. 
CMDs constructed from ground based near-IR and IRAC bands 
show that at a given luminosity some stars have dusty envelopes 
and others do not. From this, we deduce that the mass loss 
is episodic and is ``on'' for some fraction of the time.
The total mass lost on the RGB can be easily computed by multiplying ML rates 
by the ML timescales and integrating over the evolutionary timescale. 
The average total mass lost moderately increases with increasing metallicity, 
and for a given metallicity is systematically higher in clusters with extended blue HB.

A General Glivenko-Gödel Theorem for Nuclei

description: Glivenko's theorem says that, in propositional logic, classical provability of a formula entails intuitionistic provability of double negation of that formula. We generalise Glivenko's theorem from double negation to an arbitrary nucleus, from provability in a calculus to an inductively generated abstract consequence relation, and from propositional logic to any set of objects whatsoever. The resulting conservation theorem comes with precise criteria for its validity, which allow us to instantly include Gödel's counterpart for first-order predicate logic of Glivenko's theorem. The open nucleus gives us a form of the deduction theorem for positive logic, and the closed nucleus prompts a variant of the reduction from intuitionistic to minimal logic going back to Johansson.

description: Polynomial functors are a categorical generalization of the usual notion of polynomial, which has found many applications in higher categories and type theory: those are generated by polynomials consisting a set of monomials built from sets of variables. They can be organized into a cartesian bicategory, which unfortunately fails to be closed for essentially two reasons, which we address here by suitably modifying the model. Firstly, a naive closure is too large to be well-defined, which can be overcome by restricting to polynomials which are finitary. Secondly, the resulting putative closure fails to properly take the 2-categorical structure in account. We advocate here that this can be addressed by considering polynomials in groupoids, instead of sets. For those, the constructions involved into composition have to be performed up to homotopy, which is conveniently handled in the setting of homotopy type theory: we use it here to formally perform the constructions required to build our cartesian bicategory, in Agda. Notably, this requires us introducing an axiomatization in a small universe of the type of finite types, as an appropriate higher inductive type of natural numbers and bijections.

description: We define a traced pseudomonoid as a pseudomonoid in a monoidal bicategory equipped with extra structure, giving a new characterisation of Cauchy complete traced monoidal categories as algebraic structures in Prof, the monoidal bicategory of profunctors. This enables reasoning about the trace using the graphical calculus for monoidal bicategories, which we illustrate in detail. We apply our techniques to study traced ∗-autonomous categories, proving a new equivalence result between the left ⊗-trace and the right ⅋-trace, and describing a new condition under which traced ∗-autonomous categories become autonomous.

description: Using the most general form of the interpolating current of the heavy spin 1/2, $Σ_{b}$ baryon and distribution amplitudes of the nucleon, the transition form factors of the semileptonic $Σ_{b}\to Nlν$ decay are calculated in the framework of light cone QCD sum rules. It is obtained that the form factors satisfy the heavy quark effective theory relations. The obtained results for the related form factors are used to estimate the decay rate of this transition.

The use of fin-corrugated periodic surfaces for the reduction of interference from large reflecting surfaces
Creators: name: Ebbeson, Gordon Robert
Publisher: name: University of British Columbia
Year: 2010

description: The use of periodic structures to reduce interference from large reflecting surfaces is proposed. Instrument landing system (ILS) interference from large hangars and terminal buildings is cited as a typical problem. An analytical and numerical investigation of an infinite fin-corrugated surface composed of infinitely thin fins of spacing λ/2<a<λ under TM polarized plane wave illumination is described. Specular reflection from this surface can be completely converted to back-scatter in a direction opposite to the incident wave when the angle of incidence from the normal to the surface and the fin height are properly chosen. Experiments were performed at 35 and 37 GHz. using finite size fin-corrugated surfaces with fins of finite thickness under non-plane wave illumination and the results indicate that these surfaces behave essentially as predicted. In addition, the experimental surfaces remain completely effective for small oblique angles of incidence and have sufficient bandwidth for ILS applications.
Simulating the opening of a champagne bottle

description: The axially symmetric, swirl-free gas dynamics and interlinked motion of a cork stopper provoked by the opening of a champagne bottle are modelled rigorously and studied numerically. The experimental study by Liger-Belair, Cordier \& Georges (Science Advances, 5(9), 2019) animated the present investigation. Inspection analysis justifies the inviscid treatment of the expanding jet of air enriched with dissolved carbonic acid gas initially pressurised in the bottle. Solving the resulting Euler equations is facilitated through the open-source software "Clawpack". Specific enhancements allow for resolving the emerging supersonic pockets, associated with surprisingly complex shock structures, as well as the gas-stopper interaction with due accuracy. Our experimental effort provided modelling the frictional behaviour, constitutive law and reversible (de-)compression of cork. Initially, the gas expands inside the bottleneck yet sealed by the stopper, hence accelerated by the gas but decelerated by dry sliding friction. Once the stopper has passed the bottle opening, the jet rapidly assumes locally supersonic speed, where a complex shock pattern is detected. Special attention is paid to the formation and dissolution of one or even two Mach discs between the opening and the released stopper. These simulated dynamics are found to be in fairly good agreement with recent experimental findings. It also provides a first insight into the generation of the typical popping sound.

Creators: name: Aicher, Simon

description: Glutamat ist der wichtigste exzitatorische Neurotransmitter im menschlichem Gehirn und, neben der wichtigen Rolle im gesunden Gehirn, spielen Störungen der Glutamat Dynamiken bei diversen Pathologien eine Rolle beziehungsweise stehen im Verdacht, bei vielen weiteren eine Rolle zu spielen, weshalb die genaue räumliche und zeitliche Messung der Freisetzung und Wiederaufnahme von Glutamat von großer Relevanz ist. In der Vergangenheit waren die Möglichkeiten der Feststellung von Glutamat-Strömen, durch räumliche oder zeitliche Limitationen der Messmethode, begrenzt. Neu entdeckte fluoreszenzbasierte Nanosensoren, zuerst FRET-Sensoren und später die single-Fluorophor-Sensoren, eröffneten bisher nicht da gewesene Einblicke in die extrazelluläre Dynamik von Glutamat in neuronalem Gewebe. Bisher wurden diese Sensoren jedoch lediglich am Tiermodell erprobt. Das Hauptziel dieser Arbeit bestand darin, ein bisher lediglich an Nagern angewendetes Protokoll zur Messung von Glutamat-Dynamiken mittels des single-Fluorophor-Sensors iGluu zu etablieren und damit zum ersten Mal derartige extrazelluläre Glutamat-Fluoreszenzmessungen an vitalen Gewebeproben aus dem menschlichen Kortex anzuwenden. Ein Schwerpunkt lag dabei auf der Darstellung der räumlichen und zeitlichen Dynamik des Fluoreszenzsignals. Eine Glutamatfreisetzung wurde bei dem angewendeten Fluoreszenzimaging-Protokoll initial mittels chemischer Stimulation und in weiteren Schnitten mittels elektrischer Stimulation induziert. Des Weiteren wurde in dieser Arbeit der Einfluss der den extrazellulären Glutamatspiegel beeinflussenden Stoffe TBOA und Riluzol mittels dieser neuartigen Methode in vitalem menschlichem neuronalem Gewebe untersucht.

description: Working constructively, we study continuous directed complete posets (dcpos) and the Scott topology. Our two primary novelties are a notion of intrinsic apartness and a notion of sharp elements. Being apart is a positive formulation of being unequal, similar to how inhabitedness is a positive formulation of nonemptiness. To exemplify sharpness, we note that a lower real is sharp if and only if it is located. Our first main result is that for a large class of continuous dcpos, the Bridges-Vita apartness topology and the Scott topology coincide. Although we cannot expect a tight or cotransitive apartness on nontrivial dcpos, we prove that the intrinsic apartness is both tight and cotransitive when restricted to the sharp elements of a continuous dcpo. These include the strongly maximal elements, as studied by Smyth and Heckmann. We develop the theory of strongly maximal elements highlighting its connection to sharpness and the Lawson topology. Finally, we illustrate the intrinsic apartness, sharpness and strong maximality by considering several natural examples of continuous dcpos: the Cantor and Baire domains, the partial Dedekind reals and the lower reals.

Multi-grid HMC for Ginsparg-Wilson fermions

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: I describe a method that places the fermion fields and the gauge fields on different lattice spacings during the Hybrid Monte Carlo generation of Ginsparg-Wilson dynamical ensembles. The idea is motivated by Wilson's formulation of the renormalisation group. After outlining the underlying theory, I describe a method to perform most of the work of the HMC on a coarse lattice, only requiring to convert to and from the fine lattice once for each independent configuration. Because the bulk of the work takes place on the coarse lattice, including the calculation of most observables, this method saves over an order of magnitude in computer time over previous methods.
