title: A computer-based strategy for foreign-language vocabulary-learning
Creators: name: Goodfellow, Robin
Publisher: name: The Open University
Year: 1995

description: This work sets out to establish principles for the design and evaluation of a computer-based vocabulary-learning strategy for foreign language learners. The strategy is intended to assist non-beginner learners who are working on their own, to acquire new words in such a way that they will be available when needed in subsequent communicative situations.

The nature of vocabulary-learning is examined from linguistic, psychological and educational perspectives, and a strategy for autonomous learning is derived which emphasizes the processes of: selection of new items from text, mental lexicon- building through the association of items on the basis of their lexical-structural features, and practising productive recall of items by activating the same associations as were used to build the mental network. This strategy is considered from the point of view of the support it would need from a computer-based interaction, and the field of Computer-Assisted Language Learning (CALL) for vocabulary is reviewed for examples of system design which meet the strategic and interactional requirements. Specifications are produced, based on general principles for the design of computer-assisted learning, and on current technological capability to integrate large text-databases and on-line lexical tools such as dictionaries etc., within an interface which facilitates learner control and exploration. Questions of evaluation are considered, in the light of the computer's ability to record interaction data, and a psycholinguistic model of word production is proposed as a basis for assessing the learner's performance in terms of processes as well as quantitative 'end product'. A general model of deep and surface approaches to learning is then adduced to provide a way of interpreting learner subjective data, and an independent means of evaluating the quality of the learning outcome.

A system implementing the strategy is tested with learners of Spanish and English, and the quantitative and qualitative data on learning process and outcome is analyzed in depth. The system is shown to support the learning objectives for learners who adopt a deep approach, or whose approach complements the assumptions of the design in some way, and the general design principles are therefore considered as validated. Some aspects of the strategy related to lexicon-building, however, are shown to be inadequately supported, as is the capability of the system to help learners remediate surface approaches. The main conclusion of the study is that, whilst learner exploration of powerful lexical information resources is essential for autonomous vocabulary-learning, on-line tutorial help of the kind that will encourage deep rather than surface approaches, is needed to optimise the quality of the learning outcome.

description: It was shown that using multiphoton qubits, a nearly deterministic Bell-state measurement can be performed with linear optics and on-off photodetectors [Phys. Rev. Lett. 114, 113603 (2015)]. However, multiphoton qubits are generally more fragile than single-photon qubits under a lossy environment. In this paper, we propose and analyze a scheme to teleport multiphoton-qubit information using hybrid entanglement with a loss-tolerant carrier qubit. We consider three candidates for the carrier qubit: a coherent-state qubit, a single-photon polarization qubit, and a vacuum-and-single-photon qubit. We find that teleportation with the vacuum-and-single-photon qubit tolerates about 10 times greater photon losses than with the multiphoton qubit of the photon number $N \geq 4$ in the high fidelity regime ($F\geq 90\%$). The coherent-state qubit encoding may be even better than the vacuum-and-single-photon qubit as the carrier when its amplitude is as small as $α<0.78$. We further point out that the fidelity of the teleported state by our scheme is determined by loss in the carrier qubit while the success probability depends on loss only in the multiphoton qubit to be teleported. Our study implies that the hybrid architecture may complement the weaknesses of each qubit encoding.

description: Ethanol produced from grain is viewed by many as a way to reduce energy imports, levels of carbon monoxide in the air, and surplus grain stocks. Federal and State governments helped to establish the fuel ethanol industry by providing direct payments, tax exemptions, and loan guarantees. Future Policy decisions could significantly affect ethanol production and demand. Treatment of ethanol in agricultural policy is made difficult by its ties to energy, environmental, and trade policy. This bulletin provides a basis for assessing the contribution of ethanol production to national objectives.

description: We study the distribution of transmission eigenvalues of a quantum point contact with nearby impurities. In the semi-classical case (the chemical potential lies at the conductance plateau) we find that the transmission properties of this system are obtained from the ensemble of Gaussian random reflection matrices. The distribution only depends on the number of open transport channels and the average reflection eigenvalue and crosses over from the Poissonian for one open channel to the form predicted by the circuit theory in the limit of large number of open channels.

description: The main goal of the article was to discuss the importance of introducing short supply chains in the context of minimizing the adverse effects of traditional supply chains. The paper presents a case study of the Local Product of Malopolska as an example of good practice. When analyzing the concept of shortened supply chains, some significant benefits for agricultural producers, consumers and the region can be noticed. Reduction of the food chain links brings more benefits to farmers, and can contribute to avoiding the Forrester`s effect repercussions. Short food chains can be used to promote a region, as well as organic, local or traditional products. Despite the weaknesses of the local dimension of this concept, the idea contributes to sustainable development, which links economic goals, with social and environmental objectives. Presented reflections do not exhaust the subject, but only signal a topic that requires a holistic approach to the subject. / Synopsis. Celem artykułu była analiza i ocena znaczenia krótkich łańcuchów dostaw w kontekście minimalizowania niekorzystnych zjawisk występujących w klasycznych łańcuchach dostaw. W pracy przedstawiono studium przypadku Produkt Lokalny z Małopolski, jako przykład dobrych praktyk. Analizując koncepcję skróconych łańcuchów dostaw można zauważyć istotne korzyści dla producentów rolnych, dla konsumentów, a także dla regionu. Ograniczenie ogniw łańcucha żywnościowego przynosi więcej korzyści rolnikowi, a dzięki skróceniu łańcucha do minimum można uniknąć reperkusji efektu Forrestera. Krótkie łańcuchy żywnościowe można zastosować do promocji regionu, produkcji ekologicznej, czy też produktów lokalnych i tradycyjnych. Mimo słabych stron jakim jest lokalny wymiar omawianej koncepcji, idea ta przyczynia się do realizacji założeń rozwoju zrównoważonego, która łączy cele ekonomiczne, z celami społecznymi i ochroną środowiska. Przedstawione rozważania nie wyczerpują tematu, a jedynie sygnalizują zagadnienie, które wymaga całościowego podejścia do tej tematyki.

description: The activity of active galaxy may be triggered by the merge of galaxies and present-day galaxies are probably the product of successive minor mergers. The frequent galactic merges at high redshift imply that active galaxy harbors supermassive unequal-mass binary black holes in its center at least once during its life time. In this paper, we showed that the recently discovered double-lobed FR II radio galaxies are the remnants of such supermassive binary black holes. The inspiraling secondary black hole opens a gap in the accretion disk and removes the inner accretion disk when it merges into the primary black hole, leaving a big hole of about several hundreds of Schwarzschild radius in the vicinity of the post-merged supermassive black hole and leading to an interruption of jet formation. When the outer accretion disk slowly refills the big hole on a viscous time scale, the jet formation restarts and the interaction of the recurrent jets and the inter-galactic medium forms a secondary pair of lobes. We applied the model to a particular double-lobed radio source B1834+620 and showed that the orbit of the secondary is elliptical with a typical eccentricity $e \simeq 0.68$ and the mass ratio $q$ of the secondary and the primary is $0.01 \la q \la 0.4$. The accretion disk is a standard $α$-disk with $0.01 \la α\la 0.04$ and the ratio of disk half height $H$ and radius $r$ is $δ\simeq 0.01$. The model predicates that double-lobed radio structure forms only in FR II radio galaxies.

description: Osteosclerotic metaphyseal dysplasia (OSMD) is a rare autosomal recessive sclerosing skeletal dysplasia. We report on a 34-year-old patient with sandwich vertebrae, platyspondyly, osteosclerosis of the tubular bones, pathologic fractures, and anemia. In the third decade, he developed osteonecrosis of the jaws, which was progressive in spite of repeated surgical treatment over a period of 11 years. An iliac crest bone biopsy revealed the presence of hypermineralized cartilage remnants, large multinucleated osteoclasts with abnormal morphology, and inadequate bone resorption typical for osteoclast-rich osteopetrosis. After exclusion of mutations in TCIRG1 and CLCN7 we performed trio-based exome sequencing. The novel homozygous splice-site mutation c.261G>A in the gene LRRK1 was found and co-segregated with the phenotype in the family. cDNA sequencing showed nearly complete skipping of exon 3 leading to a frameshift (p.Ala34Profs*33). Osteoclasts differentiated from the patient's peripheral blood monocytes were extremely large. Instead of resorption pits these cells were only capable of superficial erosion. Phosphorylation of L-plastin at position Ser5 was strongly reduced in patient-derived osteoclasts showing a loss of function of the mutated LRRK1 kinase protein. Our analysis indicates a strong overlap of LRRK1-related OSMD with other forms of intermediate osteopetrosis, but an exceptional abnormality of osteoclast resorption. Like in other osteoclast pathologies an increased risk for progressive osteonecrosis of the jaws should be considered in OSMD, an intermediate form of osteopetrosis.

description: A systematic examination of the electronic and transport properties of 1D fluorine-saturated zigzag graphene nanoribbons (ZGNRs) is presented in this article. One publication (Withers et al., Nano Lett., 2011, 11, 3912–3916.) reported a controlled synthesis of fluorinated graphene via an electron beam, where the correlation between the conductivity of the resulting materials and the width of the fluorinated area is revealed. In order to understand the detailed transport mechanism, edge-fluorinated ZGNRs with different widths and fluorination degrees are investigated. Periodic density functional theory (DFT) is employed to determine their thermodynamic stabilities and electronic structures. The associated transport models of the selected structures are subsequently constructed. The combination of a non-equilibrium Green’s function (NEGF) and a standard Landauer equation is applied to investigate the global transport properties, such as the total current-bias voltage dependence. By projecting the corresponding lesser Green’s function on the atomic orbital basis and their spatial derivatives, the local current density maps of the selected systems are calculated. Our results suggest that specific fluorination patterns and fluorination degrees have significant impacts on conductivity. The conjugated π system is the dominate electron flux migration pathway, and the edge effect of the ZGNRs can be well observed in the local transport properties. In addition, with an asymmetric fluorination pattern, one can trigger spin-dependent transport properties, which shows its great potential for spintronics applications.

description: Here we report that negatively charged polysulfates can bind to the spike protein of SARS-CoV-2 via electrostatic interactions. Using a plaque reduction assay, we compare inhibition of SARS-CoV-2 by heparin, pentosan sulfate, linear polyglycerol sulfate (LPGS) and hyperbranched polyglycerol sulfate (HPGS). Highly sulfated LPGS is the optimal inhibitor, with a half-maximal inhibitory concentration (IC50) of 67 μg/mL (approx. 1.6 μM). This synthetic polysulfates exhibit more than 60-fold higher virus inhibitory activity than heparin (IC50: 4084 μg/mL), along with much lower anticoagulant activity. Furthermore, in molecular dynamics simulations, we verified that LPGS can bind stronger to the spike protein than heparin, and that LPGS can interact even more with the spike protein of the new N501Y and E484K variants. Our study demonstrates that the entry of SARS-CoV-2 into host cells can be blocked via electrostatic interaction, therefore LPGS can serve as a blueprint for the design of novel viral inhibitors of SARS-CoV-2.
Synchronization of spin-transfer oscillators driven by stimulated microwave currents

description: We have simulated the non-linear dynamics of networks of spin-transfer oscillators. The oscillators are magnetically uncoupled but electrically connected in series. We use a modified Landau-Lifschitz- Gilbert equation to describe the motion of each oscillator in the presence of the oscillations of all the others. We show that the oscillators of the network can be synchronized not only in frequency but also in phase. The coupling is due to the microwave components of the current induced in each oscillator by the oscillations in all the other oscillators. Our results show how the emitted microwave power of spin-transfer oscillators can be considerably enhanced by current-induced synchronization in an electrically connected network. We also discuss the possible application of our synchronization mechanism to the interpretation of the surprisingly narrow microwave spectrum in some isolated spin-transfer oscillators.

description: We study electroweak baryogenesis in the $SO(6)/SO(5)$ composite Higgs model with the third generation quarks being embedded in the $\textbf{20}'$ representation of $SO(6)$. The scalar sector contains one Higgs doublet and one real singlet, and their potential is given by the Coleman-Weinberg potential evaluated from the form factors of the lightest vector and fermion resonances. We show that the resonance masses at $\mathcal{O}(1\sim 10{\rm ~TeV})$ can generate a potential that triggers the strong first-order electroweak phase transition (SFOEWPT). The $CP$ violating phase arising from the dimension-6 operator in the top sector is sufficient to yield the observed baryon asymmetry of the universe. The SFOEWPT parameter space is detectable at the future space-based detectors.

Creators: name: Li, Yibing
Publisher: name: The Open University
Year: 1992

description: It has been reported that non-expert users have difficulties in finding reusable software components in large object-oriented programming systems and there is a need for help tools. The research reported in this thesis addresses this issue. Described in this thesis is the design of a tool called BRRR, which aims to help non-expert users overcome such difficulties. It is developed for Smalltalk-80, the target system of this research.

BRRR is a query tool with a browsing capacity. It allows users to find necessary components by query. Its design is based on the 'retrieval by reformulation' paradigm (Williams, 1984) which was originally used in the domain of information retrieval. This paradigm allows users to incrementally specify a query by reformulation. When users specify an initial query, BRRR presents the users with an example component which satisfies the query. The users can then construct further queries by using the information presented by the system. In this way, users who are not familiar with the system or who do not know exactly what they want can be guided towards the appropriate information.

During this research, two versions of BRRR were developed: BRRRl and BRRR2. BRRRl was developed initially, based on the 'retrieval by reformulation' principle. After its implementation, a formative, empirical evaluation was conducted on it with a group of users. Based on the findings of the evaluation, BRRR2, an improved version of BRRR1 was developed. BRRR2 incorporates enhanced classification methods and explanation facilities. This new version of the tool was then evaluated empirically with a group of ten users.

The empirical evaluation of BRRR2 showed encouraging results. It demonstrates that the 'retrieval by reformulation' approach used in this research could be used successfully in helping users find reusable software components in object-oriented programming systems.

description: We report the case of a fetus with sonographic characteristics of Beckwith-Wiedemann syndrome (BWS). A 30-year-old gravida 2 para 1 was referred to our fetal medicine unit with an omphalocele. Fetal macrosomia, organomegaly, and polyhydramnios but no macroglossia were detected and BWS was suspected. Genetic testing for BWS did not confirm the suspected diagnosis as the karyotype was normal. Symptomatic polyhydramnios led to repeated amnioreductions. At 35 + 5 weeks of gestation, a female neonate of 3660 g was delivered with APGAR scores of 6/7/8, after 1/5/10 min, respectively. The abnormal shape of the thorax, facial dysmorphism, need for ventilation, and generalized muscular hypotonia led to the suspicion of Kagami-Ogata syndrome (KOS), which was confirmed by genetic testing. KOS in our patient was caused by a large deletion in the MEG3-region on chromosome 14q32 affecting the maternal allele. In this report, we highlight the notion that when sonographic signs suggestive of BWS such as macrosomia, polyhydramnios, and omphalocele are present and genetic testing does not confirm the suspected diagnosis, KOS should be tested for.

description: This report address considerations in the 1990 farm bill debate for soybeans and peanuts, including market conditions, policy proposals, trade agreements, and the interactions between policy and markets for selected commodities. Soybean acreage and production declined in the 1980s, reflecting effects of Federal commodity programs, foreign competition in oilseeds production, and sluggish economic growth in many soybean importing countries. Although soybean prices are supported by a Government loan program, market prices have exceeded the loan rate in recent years. Issues for soybeans in 1990 farm legislation will include the price support level, crop substitution on program crop acreage bases, and a marketing loan for soybeans. Peanut producers in the United States have elected mandatory marketing quotas with a two-tiered price-support program. Peanuts sold within a producer's quota qualify for a higher support price than peanuts sold outside the quota. A major issue for the peanut program in forthcoming legislation is whether to continue the current program or to include peanuts in a general agricultural program with other commodities.
A Generalization of both the Method of Images and of the Classical Integral Transforms

description: A new method for the solution of initial-boundary value problems for evolution PDEs recently introduced by Fokas is generalised to multidimensions. Also the relation of this method with the method of images and with the classical integral transforms is discussed. The new method is easy to implement, yet it is applicable to problems for which the classical approaches apparently fail. As illustrative examples, initial-boundary value problems for the diffusion-convection equation in one and higher dimensions, as well as for the linearised Korteweg-de Vries equation with the space variables on the half-line are solved. The suitability of the new method for the analysis of the the long-time asymptotics is ellucidated.
title: Investigating computer-supported collaborative learning from an affective perspective
Creators: name: Issroff, Kim
Publisher: name: The Open University
Year: 1996

description: Recent research on computer-supported collaborative learning has an emphasis on cognitive factors and experimental studies. However there are contradictory findings and disagreements about the mechanisms underpinning collaborative learning. In this thesis, computer-supported collaborative learning situations are assessed with an emphasis on the affective factors, students' perceptions and aspects of the learning situation that learners themselves find important.

Three empirical studies were conducted to highlight some of these factors.The first study investigated 11 individuals and 22 pairs of students in a secondary school using a computer to fill in a worksheet about chemistry. The second study examined 61 psychology undergraduates working collaboratively at a summer school. The third study followed a group of three primary school children working collaboratively on a dynamic document in science.

The first study found differences between individuals and pairs in terms of on-task performance but no differences between them in terms of preto post-test gain. It also showed the importance of affective factors to students. The analysis of videotapes showed changes over sessions and developments over time in students' collaborative interactions. The affective findings from the first study were supported by the results of the second study which showed that the majority of students thought that it was more important to get along with their peers than to succeed in the task. In the third study, temporal features of the interaction were analysed in a longer-term collaboration.

A number of different methodologies were used in the studies and issues concerning pre- and post-testing and the use of naturalistic and experimental studies are discussed. Time-based analyses are carried out on approximately 26 hours of videotapes of collaborative interactions and these show developments in patterns of interactions.

The thesis supports Ames' (1984) view that a moral dimension is important in collaborative learning, with findings showing that the majority of students think that it is more important to get along with their peers than to get the correct answer, with this being particularly pertinent for women. Together these studies show that both the task structure and the way in which collaboration is resourced has an impact on the products, processes and outcomes of collaborative interactions.

description:
Facial Cleansers are integral part of daily skin care and widely used for the maintenance of hygiene and cleanliness. Healthy skin pH range is 5.4‑5.9. At this pH, the regular skin bacterial flora is maintained. Facial cleansers with high pH increase skin pH resulting in skin dehydration, irritation and alteration in bacterial flora. The majority of facial cleansers available in the Bangladeshi market do not disclose their pH. The skin of Bangladeshi people is becoming dull, rough and dehydrated. The aim of this study was to evaluate the pH of different brands of facial cleansers available in the Bangladeshi market to get an overview of the effect of these products on skin problems.

description: We study finite dimensional representations of current algebras, loop algebras and their quantized versions. For the current algebra of a simple Lie algebra of type {\tt ADE}, we show that Kirillov-Reshetikhin modules and Weyl modules are in fact all Demazure modules. As a consequence one obtains an elementary proof of the dimension formula for Weyl modules for the current and the loop algebra. Further, we show that the crystals of the Weyl and the Demazure module are the same up to some additional label zero arrows for the Weyl module. For the current algebra $\Lgc$ of an arbitrary simple Lie algebra, the fusion product of Demazure modules of the same level turns out to be again a Demazure module. As an application we construct the $\Lgc$-module structure of the Kac-Moody algebra $\Lhg$-module $V(\ell\Lam_0)$ as a semi-infinite fusion product of finite dimensional $\Lgc$--modules.

description: We provide optimal measurement schemes for estimating relative parameters of the quantum state of a pair of spin systems. We prove that the optimal measurements are joint measurements on the pair of systems, meaning that they cannot be achieved by local operations and classical communication. We also demonstrate that in the limit where one of the spins becomes macroscopic, our results reproduce those that are obtained by treating that spin as a classical reference direction.

description: Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way. The population synthesis approach is a useful tool to interpret such data sets and to test scenarios of evolution of the Galaxy. We present here new constraints on evolution parameters obtained from the Besancon model of population synthesis and analysis of optical and near-infrared star counts. The Galactic potential is computed self-consistently, in agreement with Hipparcos results and the observed rotation curve. Constraints are posed on the outer bulge structure, the warped and flared disc, the thick disc and the spheroid populations. The model is tuned to produce reliable predictions in the visible and the near-infrared in wide photometric bands from U to K. Finally, we describe applications such as photometric and astrometric simulations and a new classification tool based on a Bayesian probability estimator, which could be used in the framework of Virtual Observatories. As examples, samples of simulated star counts at different wavelengths and directions are also given.

Storing and processing optical information with ultra-slow light in Bose-Einstein condensates

description: We theoretically explore coherent information transfer between ultra-slow light pulses and Bose-Einstein condensates (BECs) and find that storing light pulses in BECs, by switching off the coupling field, allows the coherent condensate dynamics to process optical information. We develop a formalism, applicable in both the weak and strong probe regimes, to analyze such experiments and establish several new results. Investigating examples relevant to Rb-87 experimental parameters we see a variety of novel two-component BEC dynamics occur during the storage, including interference fringes, gentle breathing excitations, and two-component solitons. We find the dynamics when the levels |F=1, M_F=-1> and |F=2, M_F=+1> are well suited to designing controlled processing of the information. By switching the coupling field back on, the processed information is rewritten onto probe pulses which then propagate out as slow light pulses. We calculate the fidelity of information transfer between the atomic and light fields upon the switch-on and subsequent output. The fidelity is affected both by absorption of small length scale features and absorption of regions of the pulse stored near the condensate edge. In the strong probe case, we find that when the oscillator strengths for the two transitions are equal the fidelity is not strongly sensitive to the probe strength, while when they are unequal the fidelity is worse for stronger probes. Applications to distant communication between BECs, squeezed light generation and quantum information are anticipated.

Coexistence or Separation of the Superconducting, Antiferromagnetic, and Paramagnetic Phases in Quasi One-Dimensional (TMTSF)2PF6 ?

description: We report on experimental studies of the character of phase transitions in the quasi-1D organic compound (TMTSF)2PF6 in the close vicinity of the borders between the paramagnetic metal PM, antiferromagnetic insulator AF, and superconducting SC states. In order to drive the system through the phase border P_0(T_0), the sample was maintained at fixed temperature T and pressure P, whereas the critical pressure P_0 was tuned by applying the magnetic field B. In this approach, the magnetic field was used (i) for tuning (P-P_0), and (ii) for identifying the phase composition (due to qualitatively different magnetoresistance behavior in different phases). Experimentally, we measured R(B) and its temperature dependence R(B,T) in the pressure range (0 - 1)GPa. Our studies focus on the features of the magnetoresistance at the phase transition between the PM and AF phases, in the close vicinity to the superconducting transition at T~1K. We found pronounced history effects arising when the AF/PM phase border is crossed by sweeping the magnetic field: the resistance depends on a trajectory which the system arrives at a given point of the P-B-T phase space. In the transition from the PM to AF phase, the features of the PM phase extends well into the AF phase. At the opposite transition from the AF to PM phase, the features of the AF phase are observed in the PM phase. These results evidence for a macroscopically inhomogeneous state, which contains macroscopic inclusions of the minority phase. When the system is driven away from the transition, the homogeneous state is restored; upon a return motion to the phase boundary, no signatures of the minority phase are observed up to the very phase boundary.
