description: By the end of July 2020, the COVID-19 pandemic had infected more than seventeen million people and had spread to almost all countries worldwide. In response, many countries all over the world have used different methods to reduce the infection rate, such as including case isolation, the closure of schools and universities, banning public events, and mostly forcing social distancing, including local and national lockdowns. We use a Monte-Carlo (MC) based algorithm to predict the virus infection rate for different population densities using the most recent epidemic data in our work. We test the spread of the Coronavirus using three different lockdown models, and eight various combinations of constraints, which allow us to examine the efficiency of each model and constraint. In this paper, we have tested three different time-cyclic patterns of no-restrictions/lockdown patterns. This model's main prediction is that a cyclic schedule of no-restrictions/lockdown that contains at least ten days of lockdown for each time cycle can help control the virus infection. In particular, this model reduces the infection rate when accompanied by social distancing and complete isolation of symptomatic patients.

description: Inelastic neutron scattering is used to investigate the temperature dependence of spin correlations in the 3-dimensional XY antiferromagnet Ni(Cl$_{1-x}$Br$_x$)$_2$$\cdot$4SC(NH$_2$)$_2$, $ x = 0.14(1)$, tuned close to the chemical-composition-induced soft-mode transition. The local dynamic structure factor shows $\hbarω/T$ scaling behavior characteristic of a quantum critical point. The deviation of the measured critical exponent from spin wave theoretical expectations are attributed to disorder. Another effect of disorder is local excitations above the magnon band. Their energy, structure factor and temperature dependence are well explained by simple strong-bond dimers associated with Br-impurity sites.

description: The continuum random-phase approximation is extended to the one applicable to deformed nuclei. We propose two different approaches. One is based on the use of the three dimensional (3D) Green's function and the other is the small-amplitude TDHF with the absorbing-boundary condition. Both methods are based on the 3D Cartesian grid representation and applicable to systems without any symmetry on nuclear shape. The accuracy and identity of these two methods are examined with the BKN interaction. Using the full Skyrme energy functional in the small-amplitude TDHF approach, we study the isovector giant dipole states in the continuum for O-16 and for even-even Be isotopes.

description: Participatory Design (PD) is a commonly used method in Western cultures with roots in Scandinavia. After the COVID-19 pandemic, many PD practitioners have transitioned to an online space, where researchers and participants from different geographical locations can co-design together. Yet, we do not fully understand how different cultures collide, mix and blend in the online co-design space. By understanding how one’s culture influences the participation of a child, researchers can better structure sessions to elicit diverse input. This study examines a case study of researchers and participants from South Korea and the United States co-designing together. Close analysis of video recordings, analytic memos, and parent/child interview data demonstrates the ways in which children participated in design sessions. Facilitators paid special attention to various cultural sensitivities. Applying the theory of cultural awareness from public health literature, we offer implications on how scholars who are not fully embedded in the culture where co-design happens can understand other cultural norms and in response, create spaces in which co-design can occur successfully despite different cultural norms. Our findings show how different parts of the ecological systems from ideology, education systems, and ethnicity all influence children’s participation in sessions.

title: Exploring the out-of-school writing practices of three children aged 9 - 10 years old and how these practices travel across and within the domains of home and school
Creators: name: Chamberlain, Elizabeth May
Publisher: name: The Open University
Year: 2015

description: This study explores the writing practices of children aged 9-10 years across the settings of home and school. It examines the nature of the out-of-school writing practices of three case study children, within and across these domains. Additionally, it seeks to understand the children’s relationship with writing and considers if and how their writing practices travel across both domains. In examining home and school writing practices, the study took a sociocultural perspective underpinned by Bronfenbrenner’s (1979) ecological systems theory framework. A review of the relevant literature led to the utilisation of a multimodal definition of writing and the framing of the research as a qualitative, bounded case study within an interpretive, iterative enquiry. The principal research methods were the collation of the children’s writing artefacts, together with video and photographic footage of in-action practices in home settings, school observations and writing conversations. The findings reveal the ways in which these developing young writers engaged and interacted with writing differently in both settings. The trajectory of writing practices across home and school are seen to be in a recursive relationship through the transformation of writing events from one setting to another. Three key themes developed and are presented as metaphors of travel: Places, spaces and local customs; Text souvenirs and local decisions; and Domain exchange and transaction. These themes indicate the range and versatility of the children’s home writing practices. They highlight the complexity in characterising a shared definition of writing across domains. On the basis of the data, the study argues for teachers to be more aware and welcoming of children’s home writing practices in classroom activities. In so doing, teachers would be better able to build on these experiences, leading to new and shared ways of conceptualising writing in English primary classrooms. Finally, the study considers avenues for future research.

description: Many problems in science and engineering require uncertainty quantification that accounts for observed data. For example, in computational neuroscience, Neural Population Models (NPMs) are mechanistic models that describe brain physiology in a range of different states. Within computational neuroscience there is growing interest in the inverse problem of inferring NPM parameters from recordings such as the EEG (Electroencephalogram). Uncertainty quantification is essential in this application area in order to infer the mechanistic effect of interventions such as anaesthesia. This paper presents C++ software for Bayesian uncertainty quantification in the parameters of NPMs from approximately stationary data using Markov Chain Monte Carlo (MCMC). Modern MCMC methods require first order (and in some cases higher order) derivatives of the posterior density. The software presented offers two distinct methods of evaluating derivatives: finite differences and exact derivatives obtained through Algorithmic Differentiation (AD). For AD, two different implementations are used: the open source Stan Math Library and the commercially licenced dco/c++ tool distributed by NAG (Numerical Algorithms Group). The use of derivative information in MCMC sampling is demonstrated through a simple example, the noise-driven harmonic oscillator. And different methods for computing derivatives are compared. The software is written in a modular object-oriented way such that it can be extended to derivative based MCMC for other scientific domains.
Deep Radio Continuum Studies with the SKA: Evolution of Radio AGN Populations
Creators: name: Jackson, C A
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Radio emission is insensitive to dust obscuration, and the breadth of the radio luminosity function ensures that sources are detected over a wide range of redshifts at all radio flux densities. As a result, radio continuum observations are an efficient and unbiased probe of both nuclear (AGN) and star-forming activity over all cosmic epochs. The SKA's ``ultra-deep radio continuum surveys'' will provide the answers to at least three key astrophysical questions: (i) the star-formation history of the Universe, (ii) the evolution of the low-power end of the radio galaxy luminosity function and (iii) the relationship between the radio-loud AGN, star-formation and radio-quiet AGN phenomena. In this paper we discuss the AGN science that will be enabled by the deep radio continuum studies using the SKA. It is important to recognise that the sub-microJy SKA sky will be dominated by populations other than `radio-loud' AGN. In this way the SKA will not only provide an unbiased tracer of the star-formation history of the Universe but also be able to study the populations of sources we currently describe as `radio-quiet'. To illustrate this point we present simulations of the extragalactic radio sky based from models of the evolution of the radio luminosity function. From these simulations we predict typical source distributions and estimate the natural confusion limit to ultra-faint flux density limits relevant to the science and design goals of the SKA.

description: We consider a toy cosmological model with a gas of wrapped Dp-branes in 10-dimensional dilaton gravity compactified on a p-dimensional Ricci flat internal manifold. A consistent generalization of the low energy effective field equations in the presence of a conserved brane source coupled to dilaton is obtained. It is then shown that the compact dimensions are dynamically stabilized in string frame as a result of a balance between negative winding and positive momentum pressures. Curiously, when p=6, i.e. when the observed space is three dimensional, the dilaton becomes a constant and stabilization in Einstein frame is also realized.

description: We revisit the decoupling of neutrinos in the early universe with flavour oscillations. We rederive the quantum kinetic equations which determine the neutrino evolution based on a BBGKY-like hierarchy, and include for the first time the full collision term, with both on- and off-diagonal terms for all relevant reactions. We focus on the case of zero chemical potential and solve these equations numerically. We also develop an approximate scheme based on the adiabatic evolution in the matter basis. In fact, the large difference between the oscillations and cosmological time scales allows to consider averaged flavour oscillations which can speed up the numerical integration by two orders of magnitude, when combined with a direct computation of the differential system Jacobian. The approximate numerical scheme is also useful to gain more insight into the physics of neutrino decoupling. Including the most recent results on plasma thermodynamics QED corrections, we update the effective number of neutrinos to $N_{\mathrm{eff}} = 3.0440$. Finally we study the impact of flavour oscillations during neutrino decoupling on the subsequent primordial nucleosynthesis.

The analysis was carried out on data coming from the Research of Economic Activity of Polish Residents made by GUS in the second quarter of 2004 and in the fourth quarter of 2007. The results of the investigations indicate advantageous changes occurring in the field of rural unemployment, resulting from the availability of the EU funds and also from opening labour markets by some countries of the former EU-15. The changes include inter alia a reduction of the rate of unemployment and a decrease in the scale of long-term unemployment. Still, the unemployment of landless dwellers of rural areas remains a serious problem. / Synopsis.

Przedstawione wyniki badań wskazują na korzystne zmiany zachodzące w obszarze bezrobocia wiejskiego wynikające z dostępu Polski do funduszy unijnych, a także z otwarcia rynków pracy przez niektóre kraje dawnej „piętnastki”. Zmiany te dotyczą między innymi obniżenia wskaźników charakteryzujących bezrobocie oraz ograniczenia skali bezrobocia długookresowego. Nadal jednak poważnym problemem pozostaje bezrobocie dotyczące bezrolnych mieszkańców obszarów wiejskich.

description: The amount of data in real-time, such as time series and streaming data, available today continues to grow. Being able to analyze this data the moment it arrives can bring an immense added value. However, it also requires a lot of computational effort and new acceleration techniques. As a possible solution to this problem, this paper proposes a hardware architecture for Typicality and Eccentricity Data Analytic (TEDA) algorithm implemented on Field Programmable Gate Arrays (FPGA) for use in data streaming anomaly detection. TEDA is based on a new approach to outlier detection in the data stream context. In order to validate the proposals, results of the occupation and throughput of the proposed hardware are presented. Besides, the bit accurate simulation results are also presented. The project aims to Xilinx Virtex-6 xc6vlx240t-1ff1156 as the target FPGA.
title: Improved Cranial Fracture Metrics For Assessing The Protective Benefits Of Helmet Systems
Creators: name: Allanson-Bailey, Lucy Sarah
Publisher: name: The Open University
Year: 2016

description: During defeat of high velocity bullets and fragmentation, large deformations have been shown to occur on the inside of non-metallic helmet shells. If these deformations contact the underlying head there is the potential to cause injury, termed as Behind Helmet Blunt Trauma (BHBT). A method of assessing BHBT is required to fully understand the protective capability of a helmet system. Existing methods using synthetic head models are limited in their ability to predict injury outcome as a result of a lack of available injury criteria. The aim of this study was to improve the prediction of cranial fracture outcomes associated with BHBT, focusing on the effect of impact curvature and flat face diameter. Representative impact curvatures and flat face diameters were derived from helmet back face deformation measurements in free-air. An instrumented projectile was used to deliver a repeatable impact to a Bovine Scapula Model (BSM); the BSM being a fracture analogue for the cranium. Cranial fracture risk curves were developed using BSM fracture outcomes. These were developed for the different curvatures and flat face diameters tested, using the parameters of peak impact force, impact velocity, bone thickness considered in conjunction with impact velocity, and the Blunt Criterion (BC). It was concluded that flat impact diameter and radius of curvature should be measured within BHBT assessment to improve the accuracy of cranial fracture prediction. To support application of the risk curves to BHBT assessment methods, it was recommended that fracture outcome should be investigated in terms of the effect of using a rigid projectile when compared to helmet deformation. BHBT assessment methods should consider how to achieve consistent and representative stand-off. Testing should also be completed on full helmet systems as opposed to flat material samples.

description: Radar networks and multistatic synthetic aperture radars (SARs) allow overcoming the limitations of single radar sensors. However, a good synchronization of the radar sensors is crucial to avoid performance loss due to phase noise and frequency offsets. While this is usually done via cables or dedicated synchronization signals, digital radars allow for new techniques. This work proposes a new concept for the synchronization of phase-modulated continuous wave (PMCW) radars. The synchronization is performed solely by digital signal processing on the receiver side, adapting techniques known from digital communications. It mitigates effects caused by incoherency, which are phase noise, carrier frequency offsets and phase deviations of the local oscillator (LO), and sampling frequency offsets. At first, the impact of these effects is mathematically derived and analyzed in detail. Then, the proposed synchronization concept is presented, and its performance is thoroughly evaluated. Very good results are obtained not only in simulations but also in measurements with a 77-GHz radar demonstrator.

description: Properties of distributions of the number of trades in different intraday time intervals for five stocks traded in MICEX are studied. The dependence of the mean number of trades on the capital turnover is analyzed. Correlation analysis using factorial and $H_q$ moments demonstrates the multifractal nature of these distributions as well as some peculiar changes in the correlation pattern. Guided by the analogy with the analysis of particle multiplicity distributions in multiparticle production at high energies, an evolution equation relating changes in capital turnover and a number of trades is proposed. We argue that such equation can describe the observed features of the distribution of the number of trades in the stock market.

High own (unpaid) labour profitability in the countries where several up to several hundred of employees work per one person rendering unpaid labour, achieved when combined with a low labour productivity, was possible because of low costs of hired labour and high subsidies. Farms with an area of 1000-1500 hectare, employing even hired management workforce, turned out to be a very efficient tool of absorbing funds which are offered within CAP and which had been designed for supporting family farms. / Synopsis. Analiza wyników pięciu typów rolniczych gospodarstw z największej klasy wielkości ekonomicznej wykazała, że instrumenty WPR stworzone dla wspierania gospodarstw rodzinnych nie przystają do przedsiębiorstw rolnych z krajów byłego bloku wschodniego. Wysoka dochodowość pracy własnej w tych krajach, gdzie na jedną osobę świadczącą pracę nieopłaconą pracuje od kilku do kilkuset pracowników najemnych, uzyskana przy bardzo niskiej produktywności pracy, była możliwa w wyniku niskich kosztów pracy najemnej i wielusettysięcznego wsparcia w euro. Gospodarstwa o powierzchni często około 1000-1500 ha, w których zatrudnia się pracowników nawet do zarządzania, okazały się w tym przypadku sprawnym narzędziem absorpcji środków oferowanych w ramach WPR, która ma wspierać gospodarstwa rodzinne.

title: Exploring intercultural communicative competence in a distance language learning environment
Creators: name: Baumann, Uwe
Publisher: name: The Open University
Year: 2010

description: This study explores intercultural communicative competence in a distance language learning programme at the Open University in the UK. The research was based on two cohorts of distance language students of German, one at beginner and one at advanced level. This study uses an approach that combines quantitative and qualitative research methods through the use of questionnaires and in-depth, semi-structured telephone interviews.

It was established that the conceptual framework of intercultural communicative competence developed by Byram (1997b) and his collaborators is the most comprehensive and viable framework for this project. There is evidence in the literature that this framework has been used successfully in different contexts (Byram & Morgan, 1994; O’Dowd, 2006; Sercu et al., 2005a). Little research has been conducted on the development of intercultural communicative competence in adults, with the exception of Aarup Jensen et al. (1995). So this project addresses a gap in the research into intercultural communicative competence among adults. Furthermore, it focuses on a programme of language study at a distance, which is another area for which only limited research evidence could be found.

The findings of the project, both the quantitative and qualitative aspects, demonstrate that these learners gained knowledge through the study of a prescribed package of course materials, and that there is evidence of the acquisition of intercultural communicative competence of varying degrees, as stipulated in Byram’s conceptual framework. The findings also demonstrate that the framework of intercultural communicative competence would benefit from the addition of a sixth dimension to encapsulate the experiences and diverse backgrounds that specifically adult learners bring to the study of a modern foreign language: experience of life or savoir s’appuyer sur son expérience.

description: The acquisition of machine learning (ML) datasets by meas-urements for automotive radar data requires many resources and time. On the other hand, the simulation of complex traffic environments with sufficient level-of-detail is challenging, too. In this letter, a middle way is proposed in which real measurements are virtually augmented by reflections obtained from simulation models. The augmented measurements are then replayed with a hardware-based radar target simulator (RTS). This enables the fast creation of application-specific datasets, as well as advanced functionality tests of algorithms at deployment. To demonstrate the efficacy of the virtually augmented radar data, a set of test drives is augmented by virtual pedestrians performing traffic gestures. Then, a classifier trained on the created dataset is demonstrated to achieve a high classification accuracy of 84.0% on real test data.

description: We calculate the non-forward quark matrix elements for operators with two covariant derivatives in one-loop lattice perturbation theory using Wilson fermions. These matrix elements are needed in the renormalisation of the second moment of generalised parton distributions measured in lattice QCD. For some commonly used representations of the hypercubic group we determine the sets of all mixing operators and find the matrices of mixing and renormalisation factors.

description: ntroduction: Given that risk assessment tools are commonly based on male samples, the applicability to justice-involved women remains to be clarified. This study aimed at assessing (1) the predictive validity of the HCR-20 V3, the prevailing, yet primarily male-based violence risk assessment instrument, and (2) the incremental validity of the FAM, a gender-responsive supplement, for both inpatient violence and violent recidivism in justice-involved women. Methods: The sample included 452 female forensic inpatients with substance use disorder discharged from German forensic psychiatric care between 2001 and 2018. Results: ROC analyses revealed good predictive accuracy for the HCR-20 V3 while the FAM failed to provide incremental validity. Further, binary logistic regression determined several predictors of violence including personality disorder, covert/manipulative behavior, suicidal behavior/self-harm, and problematic intimate relationship. Discussion: These findings support the applicability of the HCR-20 V3 in justice-involved women with substance use disorder, while highlighting the clinical relevance of the FAM in supporting a gender-informed risk management.

description: The paper aims to present how the plant breeding financing system in Poland was changing before and after accession to the EU. Before 2004 the plant breeding in Poland was financed from grants from the state budget. Subsidies covered about 71% of breeding costs in 1996, which then decreased to only 40% in 2006. The total amount of subsidies granted to plant breeding dropped accordingly down from 200 million Polish zloty to only 50 million. After 2008 plant breeding in Poland will no longer be subsidized from the state budget. Only some subsidies to the basic research connected with plant breeding will be allowed. Breeders will have to cover their expenses on breeding activities from their own income. The main stream of money assigned to this purpose would come from breeders’ royalties. The research results indicate that the royalties will replace government subsidies, if at least 20% of farmers pay the royalties to breeders. A possibility to develop Polish plant breeding sector arises from strengthening it financially by concentration of breeding activities in selected companies and expansion of their activities on seed reproduction. / Synopsis. Celem opracowania jest przedstawienie systemu finansowania hodowli roślin w Polsce w okresie przed i po integracji z UE. Do 2008 roku hodowla roślin była wspierana z budżetu państwa, jednak kwoty dotacji systematycznie maleją, od 200 mln zł w 1997 roku do 50 mln przewidzianych na 2008 rok. Koszty hodowli były finansowane głównie dotacjami: od 71% w 1996 roku do 40% w 2006 roku. Po 2008 roku hodowla roślin nie będzie finansowana z budżetu. Możliwe będzie tylko finansowanie prac badawczych. Podstawowymi źródłami dochodów hodowców będą wpływy z opłat licencyjnych oraz z prowadzenia innych, poza hodowlą, działalności. Zastąpienie dotacji środkami własnymi będzie wymagało zwiększenia wielkości opłat otrzymywanych od rozmnożeń własnych. Systemem tym musi być objęte przynajmniej 20% rolników nie objętych odstępstwem rolnym. Jedną z możliwości zwiększenia źródeł finansowania nakładów na hodowlę jest też tworzenie przedsiębiorstw hodowlano-nasiennych.
