description: The $η^\prime g^* g^{(*)}$ effective vertex function is calculated in the QCD hard-scattering approach, taking into account the $η^\prime$-meson mass. We work in the approximation in which only one non-leading Gegenbauer moment for both the quark-antiquark and the gluonic light-cone distribution amplitudes for the $η^\prime$-meson is kept. The vertex function with one off-shell gluon is shown to have the form (valid for $| q_1^2 | > m_{η^\prime}^2$) $F_{η^\prime g^* g} (q_1^2, 0, m_{η^\prime}^2) = m_{η^\prime}^2 H(q_1^2)/(q_1^2 - m_{η^\prime}^2)$, where $H(q_1^2)$ is a slowly varying function, derived analytically in this paper. The resulting vertex function is in agreement with the phenomenologically inferred form of this vertex obtained from an analysis of the CLEO data on the $η^\prime$-meson energy spectrum in the decay $Υ(1S) \to η^\prime X$. We also present an interpolating formula for the vertex function $F_{η^\prime g^* g} (q_1^2, 0, m_{η^\prime}^2)$ for the space-like region of the virtuality $q_1^2$, which satisfies the QCD anomaly normalization for on-shell gluons and the perturbative-QCD result for the gluon virtuality $| q_1^2| \gtrsim 2$ GeV$^2$.

description: Excerpts from the report: Cotton ginning was once chiefly a farm operation, but, since the turn of the century, it has been streamlined into a highly specialized commercial activity. Facilities for the ginning of cotton in the United States make up an important industry, and charges paid for ginning services are a big item of cost to cotton growers. Growers, on the average, paid more than 160 million dollars annually for ginning services during the period 1947-48 to 1954-55. Currently, the total investment in ginning facilities is in the neighborhood of 400 million dollars.

description: Excitations of small one-dimensional matter-wave solitons are considered within a framework of the attractive Bose-Hubbard model. The initial eigenstates of the system are found by exact diagonalization of the Bose-Hubbard Hamiltonian. We drive transitions between the eigenstates by inducing a weak modulation of the tunnelling rate and show that a single atom can be extracted while the remaining atoms stay localized despite the persistent external modulation. This scheme suggests the experimental realization of small matter-wave solitons with deterministic number of atoms. In addition, the knowledge of exact eigenstates allows identification of the selection rules for transitions between the different eigenstates of the Hamiltonian. One selection rule is related to the translation symmetry of the system. Another one is strictly applicable only on a subspace of the total Hilbert space and is related to the parity symmetry. We show that in the strongly interacting limit this selection rule has implications on the entire Hilbert space. We discuss its signatures on the system's dynamics and consider how it can be observed experimentally with ultracold atoms.

description: Volcanism has both positive and negative effects. The limitation of the latter ones is admittedly difficult, however, depending on the strength and frequency of events and opportunities for the communities living in these areas is real, and the steps undertaken by them are varied. Despite the risks of inhabiting the regions of active volcanism these areas are densely populated. In the endangered areas the authorities, supported by scientists, are responsible for the effective management of risk and preparation of evacuation plans, which reduces material losses, and saves the life of the inhabitants. Thus, the question is whether and how the island society living in areas directly threatened by volcanic activity can counteract its negative effects? The article makes reference to the eruptions of located on the islands volcanoes Mont Pelée (Martinique), Soufrière Hills (Montserrat), Pinatubo (Luzon) and Helgafell (Heimaey), Ruapehu (New Zealand) and Santa Barbara (Terceira).

description: The article presents information concerning the function of organic matter in soil, natural factors affecting the content of organic matter in soils, environmental aspects and management of current problems in managing soil matter in agriculture. On the basis of author’s own research and review of subject literature the results of several years of experience on the dynamics of changes and quality of organic matter in soil have been presented. Results of indicators of the organic matter in agricultural soils indicate a wide variation of humus content (0.5-10%). The average content of this substance in our soils is 2.2% (Stuczyński et al., 2007). The aim of this article is to pay special attention to broadening the scope of research on organic matter in order to develop norms that may be necessary when developing prevention programs targeted at reducing the content of organic matter in soils, in light of the increasing acreage crops in monocultures and reducing the use of natural fertilizers in agriculture. It is also necessary to draw attention to a broader perception of soil fertility from the environmental perspective, especially in order for the increase of the humus content through various agro-technical actions not to worsen quality of water, of food and of feed.

title: Mining credit card data
Creators: name: Blunt, Gordon
Publisher: name: The Open University
Year: 2002

description: Data mining is the process of finding interesting or valuable structures in large data sets. It is a modern discipline, and takes ideas and methods from statistics, machine learning, data management and other areas. In many ways, it is similar to exploratory data analysis, although the size of current data sets distinguishes between data mining and standard exploratory data analysis. Data mining can pose novel challenges because of the amount of data to be analysed. This thesis is concerned with modelling different aspects of credit card holders' behaviour and detecting patterns in the ways customers use their card accounts. A review of the literature on consumer purchasing behaviour and data mining is given, and for the latter the differing viewpoints of the statistical and the computer science communities are discussed. Two types of models are examined: descriptive models, which describe how customers have been observed to behave; and predictive models, which predict how customers are likely to behave in the future. Both types of model are applied to the main types of credit card use: repayment behaviour and transactional behaviour. Relationships between the two different sorts of behaviour are described, and models are examined which can link the two. Some valuable insights and discoveries of potential commercial value are described. Simple graphical tools are used to illustrate the unearthing of unexpected patterns and relationships, and it is shown how more sophisticated modelling can build on such discoveries.
Gamma-radiation as a Signature of Ultra Peripheral Ion Collisions at LHC energies

description: We study the peripheral ion collisions at LHC energies in which a nucleus is excited to the discrete state and then emits $γ$-rays. Large nuclear Lorenz factor allows to observe the high energy photons up to a few ten GeV and in the region of angles of a few hundred micro-radians around the beam direction. These photons can be used for tagging the events with particle production in the central rapidity region in the ultra-peripheral collisions. For that it is necessary to have an electromagnetic detector in front of the zero degree calorimeter in the LHC experiments.

title: An exploration of the association between global expectations regarding corporate behaviour and corporate social disclosure practices of multinational organisations from culturally diverse countries
Creators: name: Newson, Marc John
Publisher: name: The Open University
Year: 2002

description: This thesis explores the social disclosure policies of large multinational organisations from culturally diverse countries. Arguments are advanced about why large multinational organisations will respond to 'global expectations', rather than simply the expectations of those people residing in the corporations' 'home' country. It is proposed that social disclosure is a reaction (or anticipation) by management to the perceived social and political environment, and that some organisations are more 'exposed' than others. It is also proposed that voluntary social disclosure is a function of country culture, but that large multinational organisations from culturally diverse countries, operating in a global market, are susceptible to borrowing a 'global culture'. Disclosure against 'global expectations' by large multinational organisations from culturally diverse countries is predicted to be a function of 'global exposure'. To determine global expectations, reliance is placed on two large international surveys conducted in 1998 and 1999. Five proxies for 'global exposure' are developed and tested relating to size, industry and stock exchange listings. The results of analysis indicate minimal alignment between global expectations, as represented by the two surveys, and the social disclosure policies of large multinational organisations. Initial results of multiple regression indicate that 'foreign listing status' is very highly significant in explaining minimal disclosure against global expectations, but this is no longer true when a control variable for 'country of origin' is added. Social disclosure practices overall, appear to be a reaction to the perceived social and political environment in the country at the time of reporting, with certain voluntary disclosures explained by recent regulatory intervention or Government initiatives. Political economy theory is adopted to explain the lack of disclosure against global expectations, and legitimacy theory is adopted to explain disclosure practices within countries overall.

description: Nowadays it is prevalent to take features extracted from pre-trained deep learning models as image representations which have achieved promising classification performance. Existing methods usually consider either object-based features or scene-based features only. However, both types of features are important for complex images like scene images, as they can complement each other. In this paper, we propose a novel type of features -- hybrid deep features, for scene images. Specifically, we exploit both object-based and scene-based features at two levels: part image level (i.e., parts of an image) and whole image level (i.e., a whole image), which produces a total number of four types of deep features. Regarding the part image level, we also propose two new slicing techniques to extract part based features. Finally, we aggregate these four types of deep features via the concatenation operator. We demonstrate the effectiveness of our hybrid deep features on three commonly used scene datasets (MIT-67, Scene-15, and Event-8), in terms of the scene image classification task. Extensive comparisons show that our introduced features can produce state-of-the-art classification accuracies which are more consistent and stable than the results of existing features across all datasets.

description: We describe 14 years of public data from the Parkes Pulsar Timing Array (PPTA), an ongoing project that is producing precise measurements of pulse times of arrival from 26 millisecond pulsars using the 64-m Parkes radio telescope with a cadence of approximately three weeks in three observing bands. A comprehensive description of the pulsar observing systems employed at the telescope since 2004 is provided, including the calibration methodology and an analysis of the stability of system components. We attempt to provide full accounting of the reduction from the raw measured Stokes parameters to pulse times of arrival to aid third parties in reproducing our results. This conversion is encapsulated in a processing pipeline designed to track provenance. Our data products include pulse times of arrival for each of the pulsars along with an initial set of pulsar parameters and noise models. The calibrated pulse profiles and timing template profiles are also available. These data represent almost 21,000 hrs of recorded data spanning over 14 years. After accounting for processes that induce time-correlated noise, 22 of the pulsars have weighted root-mean-square timing residuals of < 1 $μ$s in at least one radio band. The data should allow end users to quickly undertake their own gravitational-wave analyses (for example) without having to understand the intricacies of pulsar polarisation calibration or attain a mastery of radio-frequency interference mitigation as is required when analysing raw data files.

description: Adaptive optics imaging of the bright visual T Tauri binary AS 353 with the Subaru Telescope shows that it is a hierarchical triple system. The secondary component, located 5.6" south of AS 353A, is resolved into a subarcsecond binary, AS 353Ba and Bb, separated by 0.24". Resolved spectroscopy of the two close components shows that both have nearly identical spectral types of about M1.5. Whereas AS 353A and Ba show clear evidence for an infrared excess, AS 353Bb does not. We discuss the possible role of multiplicity in launching the large Herbig-Haro flow associated with AS 353A.

title: Epidemiological studies of inflammatory airway disease in horses
Creators: name: Newton, Jonathan Richard
Publisher: name: The Open University
Year: 2002

description: Studies of respiratory disease in different populations of horses were undertaken, including a case control study, using clinically apparent respiratory disease in Thoroughbred racehorses as the case definition. Controls were matched on date and training yard and data were analysed using conditional logistic regression. Disease was statistically associated with several infectious and non-infectious risk factors. Younger horses, those entering training within the last 3 months and those with Actinobacillus/Pasteurella spp. or Mycoplasma felis isolated from the trachea were at increased risk of clinical disease. When all controls with sub-clinical disease were excluded, tracheal Streptococcus zooepidemicus infection was significantly associated with disease.

An experimental bacterial vaccine against S. zooepidemicus and Actinobacillus spp. was evaluated for its effect on natural respiratory disease in Welsh Mountain pony foals using a blinded, randomised, controlled trial. Weekly examinations were conducted in 29 ponies, of which 12 received vaccine, 12 received placebo and 5 were untreated. Data were analysed using a multilevel modeling approach, with autoregressive variables to adjust for significant effects of disease in previous time periods. Tracheal infection with S. zooepidemicus was a significant risk factor for aggregated clinical scores and clinical signs of nasal discharge, cough and dyspnoea. There was evidence for a significant dose response between S. zooepidemicus infection and dyspnoea and inflammatory airway disease. Both pony-level and observation-level analyses demonstrated significant variation in clinical scores between ponies with transferrin haplotypes D or F2.

Tracheal and nasopharyngeal isolates of S. zooepidemicus from the ponies in the vaccination study were typed by polymerase chain reaction of the hypervariable region of the M-protein (5 possible types) and the 16S-23S RNA gene intergenic spacer (8 possible types). More S. zooepidemicus types were isolated from the trachea than the nasopharynx. There was evidence for clonal succession of types over time and novel S. zooepidemicus types were identified. There were apparent differences in the strength of association of different S. zooepidemicus types with respiratory disease in these ponies during the study period.

description: In homogeneous cosmologies, quantum geometry effects lead to a resolution of the classical singularity without having to invoke special boundary conditions at the singularity or introduce ad-hoc elements such as unphysical matter. The same effects are shown to lead to a resolution of the Schwarzschild singularity. The resulting quantum extension of space-time is likely to have significant implications to the black hole evaporation process. Similarities and differences with the situation in quantum geometrodynamics are pointed out.

title: Phenomenographic instructional design : case studies in geological mapping and materials science
Creators: name: McCracken, Janet
Publisher: name: The Open University
Year: 2002

description: This thesis explores the role for phenomenography in instructional design. Phenomenography is an educational research methodology that focuses on discovering the qualitatively different ways people experience learning a particular topic. The intent of the research is to come to understand the cognitive interactions that occur when learners attempt to make sense of difficult material, the kinds of difficulties they encounter, and the strategies they apply. This thesis considers how the analysis of these interactions may form the basis for the design of learning materials. Two case studies are presented that illustrate the utility of phenomenographic studies in the design process. The first considers how learner's conceptions of geological mapping can inform the instructional design of a print-based module on interpreting geological maps. A description of the design process details how specific elements were developed using the data, such as objectives and feedback and design guidelines are generated. The second case presented involves a study of learner's conceptions of phase diagrams in metallurgy. The results are integrated in the design of a computer-based learning module on phase diagrams. Design guidelines generated from this case focus on how the data needs to be communicated within the context of a team development environment. The data derived from phenomenographic studies provide descriptions of difficulties learners experience that are often not known to content experts or lecturers.. The two cases presented in this thesis demonstrate the gap between what the learner needs and what experts think they need. Communicating the existence of the gap to experts is discussed and design strategies that help to overcome this gap are presented. Integrating phenomenographic study in the design process complements established instructional design models and teaching practice. A four-stage design model is presented that includes generic guidelines that can be applied to any design context. A constructivist designer may use the guidelines to identify and generate problem-based learning tasks. Classroom teachers may use the guidelines to generate examination questions that encourage the learner to demonstrate their understanding of the key concepts associated with the topic of study. The goal for the work presented here is to improve instructional design practice, and in doing so, improve the experience of learning for students.
title: Feeling Happy and Healthy, Having Fun and Friends: Children's understanding of well-being: a qualitative study
Creators: name: Penington, Jodi
Publisher: name: The Open University
Year: 2002

description: Introduction: The importance of promoting health and well-being has been recognised in recent Government reports and interventions. However, health and mental health have largely been conceptualised as an absence of illness and distress, rather than a presence of positive health or wellness. There has been relatively little attention to this important area, and less work on children's understanding of well-being. Method: This study uses a small-scale qualitative approach to consider how children understand well-being. Twenty school children took part in semi-structured interviews to elicit their definitions of well-being and the thoughts, feelings and beliefs associated with life going well. The interviews were analysed using Interpretative Phenomenological Analysis. Results: Four main themes were developed from the interview data: 'self', 'self in relation to others', 'growing up' and 'the role of adults'. These were presented, illustrated with verbatim quotation from the interviews. The four themes could also be brought together under an overarching theme of self-definition. A wide range of definitions and thoughts, feelings and beliefs were generated by children in the interviews. Discussion: Children's definitions of well-being in this study reflected a more holistic definition, incorporating elements of social, emotional and physical well-being. Well-being was not understood solely in terms of an 'absence of illness'. There was some overlap with other recent conceptualisations of well-being. This is discussed in relation to the promotion of children's mental health and well-being in different settings, the development of treatment goals, and the role of the positive within psychology and other services.
title: The importance of positive cognitive processes in psychological well-being
Creators: name: Noad, Rupert Francis
Publisher: name: The Open University
Year: 2002

description: Introduction: Clinical psychologists have traditionally focused on understanding and treating psychological distress, and psychological theories have rarely been applied to understand positive psychological well-being. This project is interested in applying the principles of Cognitive Theory, a well-established model for the mechanisms underpinning psychological disorders, to understanding positive psychological states.

Method: Semi-structured interviews were conducted with undergraduate students to investigate how they think when they feel well. Items derived from these interviews were used in the design of two measures of positive cognition (one of positive core-beliefs and one of positive assumptions). These measures were administered to a larger sample of students, in a battery of questionnaires, examining other psychological variables and well-being. The results were analysed, to investigate the relationship between positive cognition and psychological well-being.

Results: The findings provide evidence in support of the psychometric properties of the two measures, suggesting that positive cognitions can be reliably and validly measured. Correlation analyses indicated a positive relationship between positive cognition and psychological well-being. Regression analyses indicated that positive core-beliefs predict psychological well-being, although self-esteem was the best predictor. Core-beliefs had some unique predictive power, when other variables were accounted for.

Discussion: The findings provide some support for the hypothesis that positive cognitions exist and are related to psychological well-being in a way predicted by cognitive theory. The study also produces two measures of positive cognition, which have the potential to be developed and used in future research. Methodological issues are discussed along with the implications of the findings for theory, clinical practice and future research.
title: Classroom explorations of mathematical writing with nine- and ten-year-olds
Creators: name: Phillips, Marilyn Eileen
Publisher: name: The Open University
Year: 2002

description: In this dissertation, writing as a teacher-researcher, I present my longitudinal explorations (1992-2002) of the area of mathematical and paramathematical writing with grade four pupils (nine- and ten-year-olds) who have been members of my classroom (a public elementary school in Vancouver, British Columbia, Canada). Five main writing sites were used: mathematical journal writing, computer research journal writing, pen-pal letter writing (in conjunction with university pre-service students), different forms of in-class extended writing including reports of mathematical investigations undertaken by the pupils and (most significantly in terms of this dissertation) pupil textbook writing. The pupil writing from the last two sites came from one year, 1997-1998. The 'writing debate' in English language concerning issues of teaching writing through 'creative process' or through explicitly teaching specific 'genre features' has a particular connection with this work, although my study is not formulated precisely within those terms. Certainly, during 1997-1998, my pupils were exposed to a variety of mathematical writing genres which contributed to their ability to produce the sophisticated textbook writing they did (even if it took me considerable time and effort in order to appreciate its nature). My analysis of their writing focuses on aspects of five key and interrelated features of writing: audience, purpose, form (genre), content and voice. Within these (increasingly overlapping and blurring) categories, I use certain tools of discourse analysis (in particular, attention to pronouns and general verb tense and mood) to identify and discuss specific features of their writing. In addition, l employ Eco's notion of model reader and Bakhtin's concept of addressivity in order to examine larger-scale features of my pupils' writing. These connect to conventional textbook forms and work reported in the research and professional literature, under the heading 'writing to learn mathematics'. I coin the term paramathematical writing, in order to discuss writing that supports mathematics even though it is not directly mathematical by itself. I identify two forms of paramathematical writing: explicit personal text alongside more overtly mathematical writing and certain syntactic choices (allied to 'voice') when writing text with the explicit intent of helping another pupil learn some mathematics. Finally, at a meta-level, throughout this dissertation, genuineness, caring and trust are themes that arise and interleave themselves through the discussion. Teacher research is examined as a generative process that produces, along with its particular products, seeds for on-going research.

description: Abstract: Engineering a low singlet-triplet energy gap (ΔEST) is necessary for efficient reverse intersystem crossing (rISC) in delayed fluorescence (DF) organic semiconductors but results in a small radiative rate that limits performance in LEDs. Here, we study a model DF material, BF2, that exhibits a strong optical absorption (absorption coefficient = 3.8 × 105 cm−1) and a relatively large ΔEST of 0.2 eV. In isolated BF2 molecules, intramolecular rISC is slow (delayed lifetime = 260 μs), but in aggregated films, BF2 generates intermolecular charge transfer (inter-CT) states on picosecond timescales. In contrast to the microsecond intramolecular rISC that is promoted by spin-orbit interactions in most isolated DF molecules, photoluminescence-detected magnetic resonance shows that these inter-CT states undergo rISC mediated by hyperfine interactions on a ~24 ns timescale and have an average electron-hole separation of ≥1.5 nm. Transfer back to the emissive singlet exciton then enables efficient DF and LED operation. Thus, access to these inter-CT states, which is possible even at low BF2 doping concentrations of 4 wt%, resolves the conflicting requirements of fast radiative emission and low ΔEST in organic DF emitters.

description: In the two correlated $B$ meson decay experiment we propose to measure intensities relating CP eigenstate ($J/ψK_{S,L}$) decays on $both$ sides, which will be measurable in future upgrades of KEK and PEP. As a CP-forbidden transition, we obtain $I(J/ψK_S, J/ψK_S, Δt) \sim \sin ^2 (2β)$. We calculate in a model independent way all the possible intensities relating final CP and flavour eigenstate decays. Under CPT-invariance, the asymmetries for processes related by CP$Δt$ vanish for $ΔΓ=0$ and measure $ΔΓ$ linearly. We notice the impossibility to isolate the sign of $\cos (2\bet a)$ without an independent knowledge of the sign of $ΔΓ$. This exhaustion of the possible Golden Plate and flavour decays provides new observables which may throw light in our present understanding of CKM physics.

description: The nearby ultra-compact multiplanetary system YZ Ceti consists of at least three planets. The orbital period of each planet is the subject of discussion in the literature due to strong aliasing in the radial velocity data. The stellar activity of this M dwarf also hampers significantly the derivation of the planetary parameters. With an additional 229 radial velocity measurements obtained since the discovery publication, we reanalyze the YZ Ceti system and resolve the alias issues. We use model comparison in the framework of Bayesian statistics and periodogram simulations based on a method by Dawson and Fabrycky to resolve the aliases. We discuss additional signals in the RV data, and derive the planetary parameters by simultaneously modeling the stellar activity with a Gaussian process regression model. To constrain the planetary parameters further we apply a stability analysis on our ensemble of Keplerian fits. We resolve the aliases: the three planets orbit the star with periods of $2.02$ d, $3.06$ d, and $4.66$ d. We also investigate an effect of the stellar rotational signal on the derivation of the planetary parameters, in particular the eccentricity of the innermost planet. Using photometry we determine the stellar rotational period to be close to $68$ d. From the absence of a transit event with TESS, we derive an upper limit of the inclination of $i_\mathrm{max} = 87.43$ deg. YZ Ceti is a prime example of a system where strong aliasing hindered the determination of the orbital periods of exoplanets. Additionally, stellar activity influences the derivation of planetary parameters and modeling them correctly is important for the reliable estimation of the orbital parameters in this specific compact system. Stability considerations then allow additional constraints to be placed on the planetary parameters.

Topological signature of deterministic chaos in short nonstationary signals from an optical parametric oscillator

description: Although deterministic chaos has been predicted to occur in the triply resonant optical parametric oscillator (TROPO) fifteen years ago, experimental evidence of chaotic behavior in this system has been lacking so far, in marked contrast with most nonlinear systems, where chaos has been actively tracked and found. This situation is probably linked to the high sensitivity of the TROPO to perturbations, which adversely affects stationary operation at high power. We report the experimental observation in this system of a burst of irregular behavior of duration 80 microseconds. Although the system is highly nonstationary over this time interval, a topological analysis allows us to extract a clearcut signature of deterministic chaos from a time series segment of only 9 base cycles (3 microseconds). This result suggests that nonstationarity is not necessarily an obstacle to the characterization of chaos.

description: Using a crossover-design, we assessed changes in 30-second chair stand test (30 s-CST), Timed Up-and-Go (TUG) and Berg Balance Scale (BBS) and energy and fatigue in older adults (N = 11) after performance of mental tasks. A Wilcoxon Sign Rank Test and a Friedman’s rank test were used to assess changes in 30 s-CST, TUG, BBS and energy and fatigue respectively. A linear mixed model was used to assess joint variance and random forest classifier and support vector machine (SVM) algorithms were used to verify results. Statistically significant declines in feelings of energy (p=.003), specifically mental energy (p=.015), and BBS (p

description: Recently, convolutional neural networks (CNNs) have set latest state-of-the-art on various human activity recognition (HAR) datasets. However, deep CNNs often require more computing resources, which limits their applications in embedded HAR. Although many successful methods have been proposed to reduce memory and FLOPs of CNNs, they often involve special network architectures designed for visual tasks, which are not suitable for deep HAR tasks with time series sensor signals, due to remarkable discrepancy. Therefore, it is necessary to develop lightweight deep models to perform HAR. As filter is the basic unit in constructing CNNs, it deserves further research whether re-designing smaller filters is applicable for deep HAR. In the paper, inspired by the idea, we proposed a lightweight CNN using Lego filters for HAR. A set of lower-dimensional filters is used as Lego bricks to be stacked for conventional filters, which does not rely on any special network structure. The local loss function is used to train model. To our knowledge, this is the first paper that proposes lightweight CNN for HAR in ubiquitous and wearable computing arena. The experiment results on five public HAR datasets, UCI-HAR dataset, OPPORTUNITY dataset, UNIMIB-SHAR dataset, PAMAP2 dataset, and WISDM dataset collected from either smartphones or multiple sensor nodes, indicate that our novel Lego CNN with local loss can greatly reduce memory and computation cost over CNN, while achieving higher accuracy. That is to say, the proposed model is smaller, faster and more accurate. Finally, we evaluate the actual performance on an Android smartphone.

description: One of the main dissipation processes acting on all scales in relativistic jets is thought to be governed by magnetic reconnection. Such dissipation processes have been studied in idealized environments, such as reconnection layers, which evolve in merging islands and lead to the production of plasmoids, ultimately resulting in efficient particle acceleration. In accretion flows onto black holes, reconnection layers can be developed and destroyed rapidly during the turbulent evolution of the flow. We present a series of two-dimensional general-relativistic magnetohydrodynamic simulations of tori accreting onto rotating black holes focusing our attention on the formation and evolution of current sheets. Initially, the tori are endowed with a poloidal magnetic field having a multi-loop structure along the radial direction and with an alternating polarity. During reconnection processes, plasmoids and plasmoid chains are developed leading to a flaring activity and hence to a variable electromagnetic luminosity. We describe the methods developed to track automatically the plasmoids that are generated and ejected during the simulation, contrasting the behaviour of multi-loop initial data with that encountered in typical simulations of accreting black holes having initial dipolar field composed of one loop only. Finally, we discuss the implications that our results have on the variability to be expected in accreting supermassive black holes.

description: We present an approximate gap equation for different crystalline structures of the LOFF phase of high density QCD at T=0. This equation is derived by using an effective condensate term obtained by averaging the inhomogeneous condensate over distances of the order of the crystal lattice size. The approximation is expected to work better far off any second order phase transition. As a function of the difference of the chemical potentials of the up and down quarks, $δμ$, we get that the octahedron is energetically favored from $δμ=Δ_0/\sqrt 2$ to $0.95Δ_0$, where $Δ_0$ is the gap for the homogeneous phase, while in the range $0.95Δ_0-1.32Δ_0$ the face centered cube prevails. At $δμ=1.32Δ_0$ a first order phase transition to the normal phase occurs.
