The Hanle Effect in 1D, 2D and 3D

description: This paper addresses the problem of scattering line polarization and the Hanle effect in one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D) media for the case of a two-level model atom without lower-level polarization and assuming complete frequency redistribution. The theoretical framework chosen for its formulation is the QED theory of Landi Degl'Innocenti (1983), which specifies the excitation state of the atoms in terms of the irreducible tensor components of the atomic density matrix. The self-consistent values of these density-matrix elements is to be determined by solving jointly the kinetic and radiative transfer equations for the Stokes parameters. We show how to achieve this by generalizing to Non-LTE polarization transfer the Jacobi-based ALI method of Olson et al. (1986) and the iterative schemes based on Gauss-Seidel iteration of Trujillo Bueno and Fabiani Bendicho (1995). These methods essentially maintain the simplicity of the Lambda-iteration method, but their convergence rate is extremely high. Finally, some 1D and 2D model calculations are presented that illustrate the effect of horizontal atmospheric inhomogeneities on magnetic and non-magnetic resonance line polarization signals.

description: This study explores the use of task that can be applied in a uniform fashion across different languages to compare levels of vocabulary development in foreign language learning. Experiment 1 tested native speakers of Russian and German and demonstrated the basic comparability of subjects’ judgments for both words and nonwords. The results for Russian showed an influence of word length which can be understood in terms of the Orthographical Depth Hypothesis. Experiment 2 applied the same task to learners of Russian and German and found that learners of Russian had achieved a lower level of vocabulary control than learners of German at comparable language exposure levels. This disadvantage for Russian can be attributed to the novelty of the Cyrillic graphemic system which restricts the accessibility of written language input at early stages. There was a nonlinear increase over time in word sensitivity that can be attributed to the increasing contribution of lexical plausibility factors at later stages of learning. Also, the lexical decision task appeared to be sensitive to inhibitory effects of concurrently studied languages, as well as decay due to lack of regular exposure. Together, these results indicate that the lexical decision task can be a useful tool for the assessment and crosslinguistic comparison of lexical development in foreign language learning.

description: Natural and cut slope instabilities are one of the main challenging problems in civil engineering infrastructures such as roads, buildings, dams and open pit mines. The failure of such slope results in loss of properties and lives. The road which connects Gutane Migiru town to Fincha sugar factory, Western, Ethiopia passes through rugged topography frequently subjected to slope stability problems which needs immediate attentions. This study identified and analyses stability of the slope along selected road sections by determining the geological and geotechnical properties of materials which compose the critical slope sections. Measurements on slope geometries, discontinuity orientations, insitu Schmidt hammer rebound test on exposed rock surface was undertaken during detailed field survey. Based on the field manifestations, four critical rock slope sections and two critical soil slope sections were identified for further stability analyses. Later, kinematic, deterministic and probabilistic methods of stability analyses were performed. The uniaxial compressive strength of rock as determined from point load index and Schmidt hammer ranges from 7.25MPa to 118.8MPa and 22.77MPa to 94.73MPa respectively. The quality of rock as determined from rock mass rating revealed that, the rock at slope section D1S3, D1S4 and D4S1 had good quality while those at slope section D1S2 had fair quality. Similarly, the result from kinematic analyses using dips software revealed that, wedge and planar mode of rock slope failure can occur at slope section D1S2, D1S3 and D1S4, D4S1 respectively. Furthermore, the results of factor of safety and probability of failure as determined by deterministic and probabilistic approaches using Rocplane, Swedge and Slide software under different saturation conditions showed that, all critical rock slopes were unstable under dynamic saturated conditions than during static dry conditions. This indicated that, the slopes were unstable when assumed to be fully saturated and subjected to seismic load. In addition, laboratory test result on soil sample indicated that, the soil is identified as sandy soils with lowest and highest liquid limit and plasticity index became 25 to 39.9 and 3 to 12.5 respectively. Similarly, factor of safety and probability of failure analyses result showed that both of the critical soil slopes were stable under all anticipated conditions except during dynamic saturated conditions. Based on the analyses result, this research work recommended proper remedial measures such as rock bolt, Anchor, soilnail and proper drainage system in the critical slope failure sections.

description: Language learning is a three-way interaction between the input, the learner, and the interactional context (Bloom, 1974). This three-way interaction provides a general framework for understanding first and second language acquisition, in both naturalistic and formal contexts. In order to elaborate this general framework, we need to model its three components: 1. The input. We need to know how the linguistic input can be structured to maximize effective learning. What aspects of the phonology, syntax, semantics, and morphology of the input does the learner use to “crack the code” of the new language? 2. The learner. We need to understand exactly how the cognitive abilities of the learner shape the process and outcome of second language instruction. 3. The context. Traditionally, the classroom environment maintains a rather uniform structure in which interaction is controlled by the instructor. How does this framework affect learning and how can it be varied to improve the learning process?

description: There is a rich literature on Bayesian methods for density estimation, which characterize the unknown density as a mixture of kernels. Such methods have advantages in terms of providing uncertainty quantification in estimation, while being adaptive to a rich variety of densities. However, relative to frequentist locally adaptive kernel methods, Bayesian approaches can be slow and unstable to implement in relying on Markov chain Monte Carlo algorithms. To maintain most of the strengths of Bayesian approaches without the computational disadvantages, we propose a class of nearest neighbor-Dirichlet mixtures. The approach starts by grouping the data into neighborhoods based on standard algorithms. Within each neighborhood, the density is characterized via a Bayesian parametric model, such as a Gaussian with unknown parameters. Assigning a Dirichlet prior to the weights on these local kernels, we obtain a pseudo-posterior for the weights and kernel parameters. A simple and embarrassingly parallel Monte Carlo algorithm is proposed to sample from the resulting pseudo-posterior for the unknown density. Desirable asymptotic properties are shown, and the methods are evaluated in simulation studies and applied to a motivating data set in the context of classification.

description: We investigate photon production in a scenario of quark-gluon plasma formation in proton-proton scattering at 7 TeV. It is shown that thermal photon yields increase quadratically with the charged particle multiplicity. This gives an enhanced weight to high multiplicity events, and leads to an important photon production even in minimum bias events, where the thermal photons largely dominate over the prompt ones at transverse momentum values smaller than 10 GeV/c.

description: We study degenerations of the Hall algebras of exact categories induced by degree functions on the set of isomorphism classes of indecomposable objects. We prove that each such degeneration of the Hall algebra $\mathcal{H}(\mathcal{E})$ of an exact category $\mathcal{E}$ is the Hall algebra of a smaller exact structure $\mathcal{E}' < \mathcal{E}$ on the same additive category $\mathcal{A}.$ When $\mathcal{E}$ is admissible in the sense of Enomoto, for any $\mathcal{E}' < \mathcal{E}$ satisfying suitable finiteness conditions, we prove that $\mathcal{H}(\mathcal{E}')$ is a degeneration of $\mathcal{H}(\mathcal{E})$ of this kind.
 In the additively finite case, all such degree functions form a simplicial cone whose face lattice reflects properties of the lattice of exact structures. For the categories of representations of Dynkin quivers, we recover degenerations of the negative part of the corresponding quantum group, as well as the associated polyhedral structure studied by Fourier, Reineke and the first author.
 Along the way, we give minor improvements to certain results of Enomoto and Brüstle-Langford-Hassoun-Roy concerning the classification of exact structures on an additive category. We prove that for each idempotent complete additive category $\mathcal{A}$, there exists an abelian category whose lattice of Serre subcategories is isomorphic to the lattice of exact structures on $\mathcal{A}$. We show that every Krull-Schmidt category admits a unique maximal admissible exact structure and that the lattice of smaller exact structures of an admissible exact structure is Boolean.

description: With the increasing popularity of microservices for software application development, businesses are migrating from monolithic approaches towards more scalable and independently deployable applications using microservice architectures. Each microservice is designed to perform one single task. However, these microservices need to be composed together to communicate and deliver complex system functionalities. There are two major approaches to compose microservices, namely choreography and orchestration. Microservice compositions are mainly built around business functionalities, therefore businesses need to choose the right composition style that best serves their business needs. In this research, we follow a five-step process for conducting a Design Science Research (DSR) methodology to define, develop and evaluate BPMN-based models for microservice compositions. We design a series of BPMN workflows as the artifacts to investigate choreography and orchestration of microservices. The objective of this research is to compare the complexity of the two leading composition techniques on small, mid-sized, and end-to-end e-commerce scenarios, using complexity metrics from the software engineering and business process literature. More specifically, we use the metrics to assess the complexity of BPMN-based models representing the abovementioned e-commerce scenarios. An important aspect of our research is the fact that we model, deploy, and run our scenarios to make sure we are assessing the modeling complexity of realistic applications. For that, we rely on Zeebe Modeler and CAMUNDA workflow engine. Finally, we use the results of our complexity assessment to uncover insights on modeling microservice choreography and orchestration and discuss the impacts of complexity on the modifiability and understandability of the proposed models.

description: The Lee-Yang zeros are one-to-one mapping to zeros in the coherence of a probe spin coupled to a many-body system. Here, we study the spin squeezing under two different types of Lee-Yang dephasing channels in which the partition functions vanish at Lee-Yang zeros. Under the first type of the channels in which probes are coupled to their own bath, we find that the performance of spin squeezing is improved and its maximum only depends on the initial state. Moreover, the centers of all the concurrence vanishing domains are corresponding to the Lee-Yang zeros. Under the second type of the channels in which probes are coupled to one bath together, the performance of spin squeezing is not improved, however, the concurrence shares almost the same properties under both channels. These results provide new experimental possibilities in many-body physics and extend a new perspective of the relationship between the entanglement and spin squeezing in probes-bath systems.

description: Petrographic, Major-and trace –element results are presented for granitoids from Berguda area which is located in the Mozambique Belt of southern Ethiopia. Based on field studies, petrographic and geochemical investigations two distinct types of granitoid intrusion were recognized: 1) the Wolena Bokosa Granitoid (WBG), 2) And Hida Korma Granitoid (HKG). In general, despite their compositional variations both groups are similarly characterized by equigranular, porphyritic and medium grained texture. These groups have intruded the hornblende-biotite gneiss and the Magnetite-quartz-feldspar gneiss. The Wolena Bokosa granitoid (WBG) is dominantly syenogranite and monzogranite and characterized by high silica content (from 73.38-79.38 wt% SiO2) and wider alumina values ranges from 10.68- 14.81 wt% Al2O3. It has relatively high molecular A/CNK (ASI) values (i.e. 0.99-1.05), scattering major- and trace- element trends, high Rb/Sr ratio (1.96 on avarage) with low contents of CaO, MgO, Fe2O3, TiO2 and P2O5. It is shoshonitic to high k-calc alkaline, weakly Peraluminous, dominantly alkali-calcic and more felsic I-type granitoid. The Hida Korma granitoid (HKG), which is composed of monzogranite and granodiorite and characterized by moderate silica content ranges from 66.02-69.26 wt% SiO2 and high alumina values which ranges between 13.21-14.61. Similarly, HKG is Ferroan (Fe-enriched), I-type, calc-alkaline affinity and shoshonitic to high k-calc alkaline. But it has relatively low molecular A/CNK values (i.e. 0.86-0.96), linear major- and trace- element trends, low Rb/Sr ratio (0.71 on averages) with high contents of CaO, MgO, FeOt, TiO2 and P2O5, more mafic I-type with metaluminous and alkalic to alkali-calc granitoid type. I-type character for both groups indicates that all of them are derived from a comagmatic source as a result of fractional crystallization and mineral differentiation. The enrichment in most incompatible elements as well as substantial positive anomalies in Rb, Th, K, Pb, Zr and significant negative in Sr, P, Ti, Nb, in both groups reflects the involvements of crustal source in their genesis. WBG is generated in volcanic arc or post-orogenic tectonic setting while HKG is generated within plate or late-orogenic tectonic setting.

description: Warm dark matter is consistent with the observations of the large-scale structure, and it can also explain the cored density profiles on smaller scales. However, it has been argued that warm dark matter could delay the star formation. This does not happen if warm dark matter is made up of keV sterile neutrinos, which can decay into X-ray photons and active neutrinos. The X-ray photons have a catalytic effect on the formation of molecular hydrogen, the essential cooling ingredient in the primordial gas. In all the cases we have examined, the overall effect of sterile dark matter is to facilitate the cooling of the gas and to reduce the minimal mass of the halo prone to collapse. We find that the X-rays from the decay of keV sterile neutrinos facilitate the collapse of the gas clouds and the subsequent star formation at high redshift.

description: Antiferromagnetic materials are promising platforms for next-generation spintronics owing to their fast dynamics and high robustness against parasitic magnetic fields. However, nanoscale imaging of the magnetic order in such materials with zero net magnetization remains a major experimental challenge. Here we show that non-collinear antiferromagnetic spin textures can be imaged by probing the magnetic noise they locally produce via thermal populations of magnons. To this end, we perform nanoscale, all-optical relaxometry with a scanning quantum sensor based on a single nitrogen-vacancy (NV) defect in diamond. Magnetic noise is detected through an increase of the spin relaxation rate of the NV defect, which results in an overall reduction of its photoluminescence signal under continuous laser illumination. As a proof-of-concept, the efficiency of the method is demonstrated by imaging various spin textures in synthetic antiferromagnets, including domain walls, spin spirals and antiferromagnetic skyrmions. This imaging procedure could be extended to a large class of intrinsic antiferromagnets and opens up new opportunities for studying the physics of localized spin wave modes for magnonics.

description: In a recent issue of this journal, Edward Gibson published a review of ‘The crosslinguistic study of sentence processing’ (CSSP) -- a book which contains several chapters summarizing our recent crosslinguistic work and those of our collaborators in several countries. The primary goal of CSSP was to explore the predictions that derive from a minimalist model of language processing and acquisition which we have called the Competition Model. Gibson’s review of CSSP exposes a set of deep fracture lines separating two competing approaches to psycholinguistics. One one side of the fault zone, the Competition Model focuses on the construction of a minimalist model designed to predict exact numerical values in controlled studies. In this approach, an initial candidate model is not responsible for predicting all levels of all variables for all sentences in all languages. Instead, the model is developed inductively on the basis of a constrained set of sentence types and certain limited predictions. On the other side of the psycholinguistic fault zone, the UG model that Gibson espouses avoids minimalism and emphasizes the complexity of the theory of formal principles of language structure motivated by binary acceptability judgments generated by small numbers of professionally-trained theoreticians

description: In this Letter we put forward a novel phenomenological paradigm in which particle physics beyond the Standard Model may be tested by radio astronomy if they are related to a first order phase transition in the early Universe. For this type of Dark Matter models, the first order phase transition takes place at KeV scales, and hence, induces the production of a stochastic gravitational wave background that can be detected from Pulsar timing measures. We demonstrate this hypothetical feasibility by studying a class of Majoron Dark Matter model, which is related to a first order phase transition of the $U(1)_{L}$ or $U(1)_{B-L}$ symmetry and is consequently dubbed as {\it violent Majoron}. This phenomenon are expected to be examined by the ongoing and forthcoming radio experiments, including FAST, SKA and IPTA.

description: Many programmers, when they encounter an error, would like to have the benefit of automatic fix suggestions---as long as they are, most of the time, adequate. Initial research in this direction has generally limited itself to specific areas, such as data structure classes with carefully designed interfaces, and relied on simple approaches. To provide high-quality fix suggestions in a broad area of applicability, the present work relies on the presence of contracts in the code, and on the availability of dynamic analysis to gather evidence on the values taken by expressions derived from the program text. The ideas have been built into the AutoFix-E2 automatic fix generator. Applications of AutoFix-E2 to general-purpose software, such as a library to manipulate documents, show that the approach provides an improvement over previous techniques, in particular purely model-based approaches.

description: It is well known that if the most energetic cosmic rays ($E>10^{20}$ eV) were protons then their acceleration sites should possess some extreme properties, including gigantic luminosity. As no stationary sources with such properties are known in the local ($D<200$ Mpc) neighborhood of the Milky Way, it is highly likely that the UHECR acceleration takes place in some transient events. In this paper we investigate scenario where the UHECRs are produced in strong AGN flares. Using more than 7 years of the Fermi-LAT observations we select candidate flares and, using correlation between jet kinetic luminosity and its bolometric luminosity, estimate local kinetic emissivity of giant AGN flares: $\mathcal{L}\sim3.7\times10^{44}\mathrm{erg~Mpc^{-3}~{yr^{-1}}}$. This value is about an order of magnitude larger than the emissivity in the CRs with $E>10^{20}$ eV, thus making this scenario feasible, if the UHECR escape spectrum is rather hard and/or narrow. This shape of spectrum is predicted in a number of present models of strong relativistic collisionless shocks. Also the scenario of acceleration in AGN flares can accommodate constraints coming from the observed arrival distribution of UHECRs. Finally, we demonstrate that in case of heavier UHECR composition all the constraints are greatly relaxed.

description: Ethiopia, like many other developing countries, is faced with escalating challenges of water supply. Abstraction of groundwater for water supply, especially for rural communities, requires an understanding of the spatial and temporal variability of ground water recharge. In this study, a semi-distributed hydrological model, SWAT (Soil-Water Assessment Tool) was applied to estimate spatial and temporal variability of recharge in Ziway watershed, Ethiopian rift. The model was calibrated and validated against observed river discharge over the period 1981–2000 and 2000-2010 using SWAT-CUP (Calibration and Uncertainty Program). The long-term (1981-2010) water balance of the SWAT model reveals that the annual precipitation of 878 mm was distributed as: surface runoff of 70 mm (7.8%), evapotranspiration of 710 mm (81.8%), and groundwater recharge of 98 mm (11.2%). From the water balance analysis, evapotranspiration is the most consuming parameter for precipitation in the area. The average annual groundwater recharge shows that a general decreasing trend from the highland (160 mm/year) towards the rift floor (34 mm/year). Both the seasonal and annual variability of groundwater recharge shows similar trend with precipitation throughout the basin. In general, the spatial and temporal groundwater recharge variability is mainly controlled by the variability of precipitation. Finally, observational data sets over longer periods with higher resolution are required to constrain model parameterization and thereby reduce uncertainty in future simulations of groundwater recharge in the area.

description: The key results on lepton-pair production in ultra-relativistic nuclear collisions are shortly reviewed, starting at the roots of pp collisions in the seventies, and ending at the perspectives of the colliders RHIC and LHC. The presence is dominated by the recent precision results from NA60 at the CERN SPS, culminating in the first measurement of the in-medium rho spectral function and the transverse flow of the associated thermal radiation. The seeming cut-off of the flow above the rho may well be the first direct hint for thermal radiation of partonic origin in nuclear collisions. The major milestones in the theoretical developments are also covered.

description: A class of models is presented, in the form of continuation monads polymorphic for first-order individuals, that is sound and complete for minimal intuitionistic predicate logic. The proofs of soundness and completeness are constructive and the computational content of their composition is, in particular, a $β$-normalisation-by-evaluation program for simply typed lambda calculus with sum types. Although the inspiration comes from Danvy's type-directed partial evaluator for the same lambda calculus, the there essential use of delimited control operators (i.e. computational effects) is avoided. The role of polymorphism is crucial -- dropping it allows one to obtain a notion of model complete for classical predicate logic. The connection between ours and Kripke models is made through a strengthening of the Double-negation Shift schema.

description: We apply the G-Theory and anomaly of ghost and anti-ghost fields in the theory of supersymmetry to study a superspace over time series data for the detection of hidden general supply and demand equilibrium in the financial market. We provide a proof of the existence of the general equilibrium point over 14-extradimensions of the new G-theory compared to M-theory of 11 dimensions model of Edward Witten. We found that the process of coupling between nonequilibrium and equilibrium spinor fields of expectation ghost fields in the superspace of time series data induces an infinitely long exact sequence of cohomology from a short exact sequence of moduli state space model. If we assume that the financial market is separated into $2$ topological spaces of supply and demand as the D-brane and anti-D-brane model, then we can use a cohomology group to compute the stability of the market as a stable point of the general equilibrium of the interaction between D-branes of the market. We obtain the result that the general equilibrium will exist if and only if the 14-th-Batalin-Vilkovisky cohomology group with the negative dimensions underlying major 14 hidden factors influencing the market is zero.

description: Emotion regulation is commonly characterized as involving conscious and intentional attempts to change felt emotions, such as, for example, through reappraisal whereby one intentionally decreases the intensity of one's emotional response to a particular stimulus or situation by reinterpreting it in a less threatening way. However, there is growing evidence and appreciation that some types of emotion regulation are unintentional or incidental, meaning that affective modulation is a consequence but not an explicit goal. For example, affect labeling involves simply verbally labeling the emotional content of an external stimulus or one's own affective responses without an intentional goal of altering emotional responses, yet has been associated with reduced affective responses at the neural and experiential levels. Although both intentional and incidental emotional regulation strategies have been associated with diminished limbic responses and self-reported distress, little previous research has directly compared their underlying neural mechanisms. In this study, we examined the extent to which incidental and intentional emotion regulation, namely, affect labeling and reappraisal, produced common and divergent neural and self-report responses to aversive images relative to an observe-only control condition in a sample of healthy older adults (N = 39). Affect labeling and reappraisal produced common activations in several prefrontal regulatory regions, with affect labeling producing stronger responses in direct comparisons. Affect labeling and reappraisal were also associated with similar decreases in amygdala activity. Finally, affect labeling and reappraisal were associated with correlated reductions in self-reported distress. Together these results point to common neurocognitive mechanisms involved in affect labeling and reappraisal, supporting the idea that intentional and incidental emotion regulation may utilize overlapping neural processes.

description: We propose a general method to study dependent data in a binary tree, where an individual in one generation gives rise to two different offspring, one of type 0 and one of type 1, in the next generation. For any specific characteristic of these individuals, we assume that the characteristic is stochastic and depends on its ancestors' only through the mother's characteristic. The dependency structure may be described by a transition probability $P(x,dy dz)$ which gives the probability that the pair of daughters' characteristics is around $(y,z)$, given that the mother's characteristic is $x$. Note that $y$, the characteristic of the daughter of type 0, and $z$, that of the daughter of type 1, may be conditionally dependent given $x$, and their respective conditional distributions may differ. We then speak of bifurcating Markov chains. We derive laws of large numbers and central limit theorems for such stochastic processes. We then apply these results to detect cellular aging in Escherichia Coli, using the data of Stewart et al. and a bifurcating autoregressive model.

description: The spherical symmetry Black holes are considered in expanding background. The singularity line and the marginally trapped tube surface behavior are discussed. In particular, we address the conditions of whether a dynamical horizon forms for these cosmological black holes. We also discuss the cosmological constant effect on these black holes and the redshift of the light which comes from the marginally trapped tube surface.

description: Substantial enhancement of nonlinear high-order harmonics generation based on Fano-resonant nanostructures has received growing interest due to their promising potential for developing integrated and advanced next-generation nanophotonic devices. In this study, going beyond conventional subwavelength structures, we propose an optothermally functional hetero-metallodielectric asymmetric eight-member octamer cluster composed of a central silicon nanodisk and peripheral disks with a phase-change material (Ge2Sb2Te5). Using full electromagnetic calculations, we show that in the amorphous phase of the surrounding particles, the oligomer acts as an all-dielectric cluster, while in the crystalline regime, the octamer turns into a hybrid metallodielectric assembly. Exploiting the exquisite ability of supporting distinct Fano lineshapes at different wavelengths depending on the phase of Ge2Sb2Te5, we showed the generation of both second and third harmonics at amorphous and crystalline phases of GST nanodisks, respectively with the produced harmonic wavelengths of 425 nm and 317 nm, respectively. Our calculations for the corresponding conversion efficiencies revealed significant enhancements as ηSHG=0.012% and ηTHG=0.0081% for SHG and THG, respectively. Such an exquisite feature of multiresonant optothermally tunable cluster allows generation of several higher-harmonics with distinct intensities using a single system for future photonics applications.

Fine mesh limit of the VRJP in dimension one and Bass-Burdzy flow

description: We introduce a continuous space limit of the Vertex Reinforced Jump Process (VRJP) in dimension one, which we call Linearly Reinforced Motion (LRM) on $\R$. It is constructed out of a convergent Bass-Burdzy flow. The proof goes through the representation of the VRJP as a mixture of Markov jump processes. As a by-product this gives a representation in terms of a mixture of diffusions of the LRM and of the Bass-Burdzy flow itself. We also show that our continuous space limit can be obtained out of the Edge Reinforced Random Walk (ERRW), since the ERRW and the VRJP are known to be closely related. Compared to the discrete space processes, the LRM has an additional symmetry in the initial local times (initial occupation profile): changing them amounts to a deterministic change of the space and time scales.

description: Abstract: "This article describes recent work that utilizes the concept of chunking as the basis for an integrated model of the acquisition of both skill and knowledge. We look at results in the areas of practice (skill) and verbal learning (knowledge). The approach is based on viewing task performance as a problem solving process and chunking as a learning process that stores away information about the results of problem solving. In practice tasks, chunks acquired during the solution of one problem can be used during later problems to speed up the system's performance. This chunking process produces the same type of power-law practice curves that appear so ubiquitously in human practice. In verbal learning tasks, chunks acquired during training are used at test time to determine how to respond. This psychological model is a manifestation of a set of processes that provide the basis of a general architecture. Such an architecture is not only interesting in its own right, but provides support for the more narrowly based psychological phenomena."
