Year: 2009
Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We propose to use bifurcation theory and pattern formation as theoretical probes for various hypotheses about the neural organization of the brain. This allows us to make predictions about the kinds of patterns that should be observed in the activity of real brains through, e.g. optical imaging, and opens the door to the design of experiments to test these hypotheses. We study the specific problem of visual edges and textures perception and suggest that these features may be represented at the population level in the visual cortex as a specific second-order tensor, the structure tensor, perhaps within a hypercolumn. We then extend the classical ring model to this case and show that its natural framework is the non-Euclidean hyperbolic geometry. This brings in the beautiful structure of its group of isometries and certain of its subgroups which have a direct interpretation in terms of the organization of the neural populations that are assumed to encode the structure tensor. By studying the bifurcations of the solutions of the structure tensor equations, the analog of the classical Wilson and Cowan equations, under the assumption of invariance with respect to the action of these subgroups, we predict the appearance of characteristic patterns. These patterns can be described by what we call hyperbolic or H-planforms that are reminiscent of Euclidean planar waves and of the planforms that were used in [1, 2] to account for some visual hallucinations. If these patterns could be observed through brain imaging techniques they would reveal the built-in or acquired invariance of the neural organization to the action of the corresponding subgroups.

title: The Effects of a Calcium Pectinate Film upon Shrinkage, Palatability and Surface Microbial Growth on Carcasses and Selected Beef and Poultry Cuts
Creators: name: Stubbs, Clifford Arthur
Publisher: name: Utah State University
Year: 1980

description: A process in which low methoxyl pectin is applied to the surface of meat carcasses and poultry to reduce shrinkage, maintain color and improve shelf life was evaluated. A 3.0 percent aqueous low methoxyl pectin (acidified with 1.4 percent acetic acid if required) was applied to beef, lamb and turkey carcasses by spraying and caused to form a gel coating by overspraying with a 3.5 percent calcium chloride salt solution.
Turkey carcasses treated with acidified pectin or acidified pectin after 3.0 percent acetic acid dip for 30 seconds were not significantly improved in shelf life over carcasses which were acid dipped 30 seconds. Pectin coating of turkey carcasses was determined infeasible due to discoloration.
Pectin coated lamb carcasses were significantly lower in shrinkage (0.71 ±0.04 percent) (p

description: Fortuin-Kastelyn clusters in the critical $Q$-state Potts model are conformally invariant fractals. We obtain simulation results for the fractal dimension of the complete and external (accessible) hulls for Q=1, 2, 3, and 4, on clusters that wrap around a cylindrical system. We find excellent agreement between these results and theoretical predictions. We also obtain the probability distributions of the hull lengths and maximal heights of the clusters in this geometry and provide a conjecture for their form.

“Stepping-Stone” versus “Dead-End” Jobs: Occupational Structure, Work Experience, and Mobility Out of Low-Wage Jobs

Publisher: name: SAGE Publications

description: Does working in a low-wage job lead to increased opportunities for upward mobility, or is it a dead-end that traps workers? In this article, we examine whether low-wage jobs are “stepping-stones” that enable workers to move to higher-paid jobs that are linked by institutional mobility ladders and skill transferability. To identify occupational linkages, we create two measures of occupational similarity using data on occupational mobility from matched samples of the Current Population Survey (CPS) and data on multiple dimensions of job skills from the O*NET. We test whether work experience in low-wage occupations increases mobility between linked occupations that results in upward wage mobility. Our analysis uses longitudinal data on low-wage workers from the 1979 National Longitudinal Study of Youth (NLSY) and the 1996 to 2008 panels of the Survey of Income and Program Participation (SIPP). We test the stepping-stone perspective using multinomial conditional logit (MCL) models, which allow us to analyze the joint effects of work experience and occupational linkages on achieving upward wage mobility. We find evidence for stepping-stone mobility in certain areas of the low-wage occupational structure. In these occupations, low-wage workers can acquire skills through work experience that facilitate upward mobility through occupational changes to skill and institutionally linked occupations.

description: In the context of Markov processes, both in discrete and continuous setting, we show a general relation between duality functions and symmetries of the generator. If the generator can be written in the form of a Hamiltonian of a quantum spin system, then the "hidden" symmetries are easily derived. We illustrate our approach in processes of symmetric exclusion type, in which the symmetry is of SU(2) type, as well as for the Kipnis-Marchioro-Presutti (KMP) model for which we unveil its SU(1,1) symmetry. The KMP model is in turn an instantaneous thermalization limit of the energy process associated to a large family of models of interacting diffusions, which we call Brownian energy process (BEP) and which all possess the SU(1,1) symmetry. We treat in details the case where the system is in contact with reservoirs and the dual process becomes absorbing.

title: A Nutrition Education Component for High School Health Curriculums
Creators: name: German, Mary Jane
Publisher: name: Utah State University
Year: 1980

description: Adolescents, who have been shown to be at nutritional risk, and having poor nutritional knowledge and sporadic eating habits, are in need of comprehensive, sequential nutrition education. The purpose of this study was to develop, implement, and evaluate a nutrition education unit for inclusion in the health education curriculum of secondary schools. The two-week unit which included nutrient density concepts was evaluated in two high schools in Utah.
Data from a mail survey of health educators (n=74) revealed their need for nutrition training and resources, and guidance for integrating nutrition into health classes. High school health teachers were provided with teacher training materials, lesson plans and instructional aids. Four treatment groups (n=92) were exposed to the nutrition unit and two control groups (n=45) received no nutrition information during the test period. All subjects were pre- and post-tested to determine change in knowledge of and attitude toward nutrition, and completed food frequency questionnaires for purposes of measuring behavioral changes.
The treatment groups improved their nutrition test scores by 12 percentage points from pre- to post-test. Students were shown to reliably mark semantic differential scales measuring attitude. Overall attitude toward nutrition improved slightly. The nutrient density concept was mastered by students and proven to be an effective nutrition education tool. Post-food frequency data showed a consistent trend of decreased frequency of almost all food categories for controls as well as treatment groups, illustrating the importance of control groups in nutrition education studies. Participating health teachers positively evaluated the unit and indicated that their nutrition training and resource needs were sufficiently met.

description: Within the framework of macroscopic quantum electrodynamics in linear, causal media, we study the van der Waals potentials of ground-state atoms in planar magnetodielectric host media. Our investigation extends earlier ones in two aspects: It allows for the atom to be embedded in a medium, thus covers many more realistic systems; and it takes account of the local-field correction. Two- and three-layer configurations are treated in detail both analytically and numerically. It is shown that an interplay of electric and magnetic properties in neighbouring media may give rise to potential wells or walls. Local-field corrections as high as 80% are found. By calculating the full potential including the translationally invariant and variant parts, we propose a way to estimate the (finite) value of the dispersion potential at the surface between two media. Connection with earlier work intended for biological applications is established.

title: Statistical Models of I-15 Bridge C-846: Changes in Natural Frequencies due to Temperature
Creators: name: Nichols, Gilbert
Publisher: name: Utah State University
Year: 2017

description: Structural Health monitoring is to determine the condition of a bridge based on instrument measurements. The C-846 Bridge in Salt Lake City has such instrumentation. The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.
In light of recent research, damage may be detected from measuring the change in the natural frequency of a bridge, which can be obtained by manipulating the accelerometer data. However, the natural frequencies of a bridge change due to environmental effects, especially temperature. Temperature effects must be accounted for in order to better understand the damage.
The purpose of this research is not to detect damage. The bridge that is being monitored does not have any damage. The purpose of this study is to show how the dynamic properties of the C-846 Bridge in South Salt Lake City correlate with temperature. Additionally, several frequencies including the fundamental frequency of the bridge are identified.
It was found that the natural frequencies of the bridge increase with a decrease in temperature, and that the fundamental frequency of the bridge is 1.15 Hz.

description: Amidst the terribly rapid changing world of fashion, local Indonesian people are able to maintain the authenticity of their local fashion. The ability to preserve authenticity is reflected in the unique and distinctive nuances of local Indonesian batik. By focusing on the Tuban community, specifically on their life cycle rites, this study aims to reveal the reproductive capacity of the local Indonesian community. Using a qualitative approach, this study discloses how to reproduce the gedhog woven batik cloth in Kerek Village, Tuban, through rituals that are part of their life cycle from birth, marriage, and death. This concept is carried out by ritual rites at various periods of human life, all while wearing gedhog weaved batik cloth, which is regarded a traditional textile (wastra). This survival of batik gedhog against global fashion development. By conducting in-depth interviews, documentation and observation, these specific data was obtained from the raw materials of gedhog batik cloth available. This study found that ritual activities underpin the existence of gedhog woven batik and it is passed on to the younger generation not to mention the economic benefits it provides. This research contributes to increase the economy for women weavers and batik artisans who carry out activities in their yard as a daily activity. The results of this study have the possibility to become materials for local governments to make policies related to the efforts in increasing the production of batik and gedhog woven craftsmen at the local and national levels.

title: Optimization of Roadway Electrification Integrating Wireless Power Transfer: TechnoEconomic Assessment and Lifecycle Analysis
Creators: name: Limb, Braden J
Publisher: name: Utah State University
Year: 2017

description: Electric vehicles are the main technology currently being pursued to reduce dependence on fossil fuels in the transportation sector. These vehicles provide both reduced greenhouse gas emissions and decreased operating costs when compared to conventional internal combustion vehicles, while providing the flexibility to use both renewable and fossil energy. However, these vehicles have seen limited consumer adoption due to their large purchase prices and limited driving range. Both purchase price and driving range are related to the large onboard battery systems required for electric vehicle travel.
One solution to decrease dependence on large battery systems has focused on charging vehicles in-motion using wireless power transfer. In-motion charging of electric vehicles would allow for longer range travel with smaller onboard battery systems which would lead to cheaper vehicles and, in turn, greater consumer acceptance. Wireless power transfer is commonly used for small electronics (i.e. cell phones), but has seen limited use on large scale projects. Therefore, limited work has been done to understand the feasibility of in-motion charging of electric vehicles using wireless power transfer.
The goal of this thesis is to better understand the economic feasibility, environmental benefit, and infrastructure requirements of a wirelessly charged electric vehicle fleet for transportation in the United States.

description: We study the Schrödinger equation which comes from the paraxial approximation of the Helmholtz equation in the case where the direction of propagation is tilted with respect to the boundary of the domain. In a first part, a mathematical analysis is made which leads to an analytical formula of the solution in the simple case where the refraction index and the absorption coefficients are constant. Afterwards, we propose a numerical method for solving the initial problem which uses the previous analytical expression. Numerical results are presented. We also sketch an extension to a time dependant model which is relevant for laser plasma interaction.

description: In the wake of the pandemic crisis, findable, accessible, interoperable and reusable (FAIR) data has become crucial in order to develop next generation medicines that will change the life of patients. At Novo Nordisk, the use of ontologies and persistent identifiers to uniquely identify datasets and complex scientific vocabularies is a key factor in the development of machine learning-driven analytics. Developing ontologies from scratch is not necessary, instead, existing ontologies can be enriched with domain specific knowledge. FAIR assessment are a useful tool to plan strategies for improving reuse of data by R&D users. Curathons can be used to identify bottlenecks and anti-patterns in the data flow. Precompetitive collaborations such as the Allotrope Foundation can allow enterprise to unite their forces in harnessing scientific data to develop advanced new medicines

The relativistic real energy levels and corresponding eigenfunctions for the bound states with different screening parameters have been given in a closed form. It is found that the solutions in the case of constant mass and in the case of s-wave ($l=0$) are identical with the ones obtained in literature.

Adiabatic demagnetization apparatus for nuclear orientation
Creators: name: Gorling, Robert Lloyd Albert
Publisher: name: University of British Columbia
Year: 2011

description: A cryostat has been built for cooling specimens to temperatures of the order of a hundredth of a Kelvin by thermal contact with an adiabatically demagnetized paramagnetic salt pill. The apparatus was designed for performing nuclear orientation experiments. This thesis describes the construction of the apparatus and experimental tests studying the nuclear orientation of (60)Co in an iron plate. The paramagnetic salt used was chromium potassium alum in an alum-glycerine slurry. In addition to the chrome alum pill a guard pill of manganous ammonium sulphate was used between the alum pill and the 1K helium bath. The pills were supported and thermally isolated by German silver spacers. A copper heat link was embedded in the alum-glycerine slurry and soldered to the specimen to provide thermal contact. Several heat links were used ranging from a bundle of five thousand copper wires to a copper foil "concertina" arrangement. A Ventron niobium-titanium superconducting solenoid which produced fields up to 48 kilogauss was used for the magnetic cooling. A superconducting polarizing solenoid was used to magnetically saturate the polycrystalline iron plate. Anisotropies in the gamma radiation intensity from (60)Co of 7 to 11 per cent corresponding to temperatures of 37 to 45 m K were observed.
\I wouldn't teach any other grade\" : a case study of kindergarten teachers' work"
Creators: name: Kelly, Michael
Publisher: name: University Of Tasmania
Year: 2023

description: Whilst the nature of teachers' work in primary and secondary contexts has been the focus of considerable investigation, in the field of early childhood education, kindergarten teachers' work has been under researched. This has important implications for the field, specifically that the work of kindergarten teachers is not understood. Consequently, the work of kindergarten teachers is often under-valued and accorded a lower status than that of their colleagues in other teaching settings. The study provides an in-depth examination of four kindergarten teachers' work with the aim of illustrating the complex and diverse nature of kindergarten teaching. A second aim of the study was to gain an understanding of how individuals came to teach in kindergarten, the roles that kindergarten teachers are required to adopt, and what it means to be a kindergarten teacher. An ethnographic, narrative, case study approach to the research was adopted. Extensive observations and interviews of four kindergarten teachers working in government schools in northern Tasmania were employed to examine the nature of kindergarten teachers' work and the meaning of that work for these teachers. Through this study, a framework for understanding the nature of kindergarten teachers' work emerged. The framework takes into account the personal, professional and social dimensions of kindergarten teachers' work. The findings associated with the personal dimension suggest that these participants entered the area of kindergarten education through serendipitous circumstances or opportunities. The participants described their work as hard although kindergarten teaching was also viewed as being rewarding and a privilege despite the low status and lack of understanding that had been associated with their work. The professional dimension of kindergarten teachers' work revealed the participants were required to adopt diverse roles that can be divided into three broad categories; roles that reflect the purposes of kindergarten education such as introducing children and their families to formal schooling; roles that are related to specific aspects of kindergarten teachers' work which included the role of facilitator or social worker; and general roles such as being keeper of the peace or comforting children. The participants in this study often worked in relative isolation from other teachers, senior members of staff and their school's principal. The findings of the study suggest that the social dimension was influenced by the physical design or location of the kindergarten classroom, timetable differences between the kindergarten and the rest of the school and kindergarten teachers' perceptions that their work is misunderstood by those not involved in kindergarten teaching.
title: Integrated Life Cycle and Techno-economic Assessment of the Conversion of High Productivity, Low Lipid Algae to Renewable Fuels
Creators: name: De Mill, Chad R
Publisher: name: Utah State University
Year: 2017

description: The production of alternative transportation fuels is imperative to meet future energy demands without contributing to global climate change. Advances in alternative processing techniques that have emerged due to interest in microalgae as a feedstock have led to a variety of potential processing pathways for the production of bio-based fuels. A major hurdle in the algal production process is maintaining a fast and stable algae culture. Monocultures, developed for their high lipid content, suffer from low productivity, are susceptible to crashes and require a constant supply of carbon dioxide to maintain productivity. In an effort to circumvent these obstacles, algal turf scrubber systems (ATS) are now being targeted not only for water purification, but as a means of producing algae feedstocks for fuel conversion. The resulting algae are capable of being harvested at a much higher density, requiring less energy for dewatering purposes. ATS systems do present other drawbacks that downstream technologies need to account for to make this system a viable means for fuel conversion. While polyculture algae species display great growth characteristics, they contain high percentages of nitrogen containing proteins and low lipid content. If not removed this nitrogen pollutes any resulting biocrude making it unacceptable for diesel fuel blends. This study investigates a processing method which reduces the nitrogen content of the resulting fuel by fermenting both carbohydrates and proteins into intermediate compounds. By tuning the E. coli fermentation stain it is hoped that the process will yield higher value co-products than those investigated in this study. The research contained herein incorporates laboratory experimentation with engineering systems modeling to assess the economic feasibility and environmental impacts of generating biofuels from ATS cultivated algae. Results show a minimum fuel selling price of $5.93 per gasoline gallon equivalent and greenhouse gas emissions of -0.0185 kg CO2eq per MJ fuel. Discussion points include process optimization in terms of minimum fuel selling price and global warming potential.

description: Particle image velocimetry (PIV) is a widely used fluid measurement technique. Three dimensional PIV data or stereo PIV is acquired using two cameras. Stereo cameras are calibrated from camera coordinates, pixels, to real world units such as millimeters using calibration models. Stereo calibration is fundamental to the accuracy of a PIV measurement. In this thesis, the accuracy of the stereo calibration is assessed. The mean error of stereo calibration was found to be 0.23%.

description: We obtain an infinite sequence of bosonic non-local conserved quantities for the N=1 supersymmetric Korteweg-de Vries equation. It is generated from a bosonic non-local conserved quantity of Super Gardner equation. In distinction to the already known one with odd parity and dimension 1/2, it has even parity and dimension 1. It fits exactly in the supersymmetric cohomology in the space of conserved quantities that we also introduce here. Using results from this cohomology we obtain the Poisson bracket of several non-local conserved quantities, including the already known odd ones and the new even ones. The algebra closes in terms of polynomials of local and non-local conserved quantities. We prove that the bosonic non-local conserved quantities cannot be expressed as functions of the already known local and non-local conserved quantities of Super KdV equation.

description: Background: Persistence of HIV-1 in reservoirs necessitates life-long antiretroviral therapy (ART). There are conflicting data using genetic analysis on whether persistence includes an actively replicating reservoir with strong evidence arguing against replication.
Methods: We investigated the possibility of ongoing viral evolution during suppressive therapy by comparing near full-length viral genomic sequences using phylogenetic analysis of viral RNA in plasma before therapy initiation early after infection and from virus induced to grow from the latent reservoir after a period of suppressive ART. We also focused our analysis on evidence of selective pressure by drugs in the treatment regimen and at sites of selective pressure by the adaptive immune response.
Results: Viral genomes induced to grow from the latent reservoir from 10 participants with up to 9 years on suppressive ART were highly similar to the nearly homogeneous sequences in plasma taken early after infection at ART initiation. This finding was consistent across the entire genome and when the analysis focused on sites targeted by the drug regimen and by host selective pressure of antibody and cytotoxic T cells. The lack of viral evolution away from pretherapy sequences in spite of demonstrated selective pressure is most consistent with a lack of viral replication during reservoir persistence.
Conclusions: These results do not support ongoing viral replication as a mechanism of HIV-1 persistence during suppressive ART.

description: Community networks (CNs) have become an important paradigm for providing essential Internet connectivity in unserved and underserved areas across the world. However, an indispensable part for CNs is network management, where responsive and autonomous maintenance is much needed. With the technological advancement in telecommunications networks, a classical satellite-dependent CN is envisioned to be transformed into a satellite-integrated CN (SICN), which will embrace significant autonomy, intelligence, and scalability in network management. This article discusses the machine-learning (ML) based hierarchical approach to enabling autonomous self-maintenance for SICNs. The approach is split into the anomaly identification and anomaly mitigation phases, where the related ML methods, data collection means, deployment options, and mitigation schemes are presented. With the case study, we discuss a typical scenario using satellite and fixed connections as backhaul options and show the effectiveness and performance improvements of the proposed approach with recurrent neural network and ensemble methods
title: Microstructure and Rheology of Process Cheese
Creators: name: Rayan, Abdelaziz Hassan
Publisher: name: Utah State University
Year: 1980

description: Four batches of pasteurized process cheese were prepared from the same Cheddar cheese by cooking to 82C in the presence of sodium citrate, disodium phosphate, tetrasodium pyrophosphate or sodium aluminum phosphate. Each batch contained the same moisture (40.6%) and emulsifying salt concentration (2.5%). The process cheese was sampled for microstructural and rheological examination after 0, 5, 10, 20 and 40 min in the cooker at 82C.
Even though each emulsifying salt affected the physical properties of the process cheese differently, the cheese generally became firmer, stiffer, more elastic and less meltable as cooking time increased from 0 to 40 min. These changes were accompanied by a decrease in the dimension of fat masses and an increase in the degree of emulsification as evidenced by scanning electron microscopy and transmission electron microscopy. The degree of emulsification (fineness of fat particles) seemed directly related to firmness, poor meltability, toughness, breaking force, apparent stiffness modulus, degree of elasticity , apparent ultimate stress and inversely related to hysteresis and apparent ultimate strain. Tetrasodium pyrophosphate produced the most rapid emulsification of the fat in the cheese and sodium aluminum phosphate the slowest. The effect of the other salts was intermediate. The softest most meltable cheese was poorly emulsified while the firmest most sliceable was well emulsified.
Sodium citrate and tetrasodium pyrophosphate crystals remained undissolved in the cheese after 40 min in the cooker while sodium aluminum phosphate crystals were still undissolved after 10 min.
There was a close statistical relationship among several of the rheological measurements viz. meltability and firmness, toughness and breaking force, and meltability and breaking force. Future rheological studies on process cheese should not require all of the above measurements. An increase in the fineness of the fat emulsion as determined by scanning electron microscopy was generally accompanied by increased firmness, poorer meltability and increased toughness.

description: Central exclusive Higgs boson production, pp -> p+H+p, at the LHC can provide important complementary contribution to the comprehensive study of the Higgs sector in a remarkably clean topology. The bb(bar) Higgs decay mode is especially attractive, and for certain BSM scenarios may even become the discovery channel. Obvious requirements for the success of such exclusive measurements are strongly suppressed and controllable backgrounds. One potential source of background comes from additional gluon radiation which leads to a three-jet bb(bar)g final state. We perform an explicit calculation of the subprocesses gg -> q(bar)qg, gg -> ggg in the case of `internal' gluon radiation from the spectator, t-channel screening gluon, when the two incoming active t-channel gluons form a colour octet. We find that the overall contribution of this source of background is orders of magnitude lower than that caused by the main irreducible background resulting from the gg^{PP} -> b(bar)b subprocess. Therefore, this background contribution can be safely neglected.

description: We report a fast, room temperature detection scheme for the polarization ellipticity of laser radiation, with a bandwidth that stretches from the infrared to the terahertz range. The device consists of two elements, one in front of the other, that detect the polarization ellipticity and the azimuthal angle of the ellipse. The elements respectively utilise the circular photogalvanic effect in a narrow gap semiconductor and the linear photogalvanic effect in a bulk piezoelectric semiconductor. For the former we characterized both a HgTe quantum well and bulk Te, and for the latter, bulk GaAs. In contrast with optical methods our device is an easy to handle all-electric approach, which we demonstrated by applying a large number of different lasers from low power, continuous wave systems to high power, pulsed sources.

description: Basic properties of cold Bose atoms in optical lattices are reviewed. The main principles of correct self-consistent description of arbitrary systems with Bose-Einstein condensate are formulated. Theoretical methods for describing regular periodic lattices are presented. A special attention is paid to the discussion of Bose-atom properties in the frame of the boson Hubbard model. Optical lattices with arbitrary strong disorder, induced by random potentials, are treated. Possible applications of cold atoms in optical lattices are discussed, with an emphasis of their usefulness for quantum information processing and quantum computing. An important feature of the present review article, distinguishing it from other review works, is that theoretical fundamentals here are not just mentioned in brief, but are thoroughly explained. This makes it easy for the reader to follow the principal points without the immediate necessity of resorting to numerous publications in the field.

description: How can we perform knowledge reasoning over temporal knowledge graphs (TKGs)? TKGs represent facts about entities and their relations, where each fact is associated with a timestamp. Reasoning over TKGs, i.e., inferring new facts from time-evolving KGs, is crucial for many applications to provide intelligent services. However, despite the prevalence of real-world data that can be represented as TKGs, most methods focus on reasoning over static knowledge graphs, or cannot predict future events. In this paper, we present a problem formulation that unifies the two major problems that need to be addressed for an effective reasoning over TKGs, namely, modeling the event time and the evolving network structure. Our proposed method EvoKG jointly models both tasks in an effective framework, which captures the ever-changing structural and temporal dynamics in TKGs via recurrent event modeling, and models the interactions between entities based on the temporal neighborhood aggregation framework. Further, EvoKG achieves an accurate modeling of event time, using flexible and efficient mechanisms based on neural density estimation. Experiments show that EvoKG outperforms existing methods in terms of effectiveness (up to 77% and 116% more accurate time and link prediction) and efficiency.

Configuration interaction in the internal acceptor states in silicon

description: The presence of configuration interaction, between the "internal" acceptor states of group III impurities in silicon and P₃⁄₂ band Bloch states, has been observed. The effect of impurity-impurity interaction on the line shape of the boron, gallium and indium internal acceptor lines has been studied. The observed characteristic asymmetric line shape is explained by introducing the interaction of the internal state with the degenerate P₃⁄₂ valence band Bloch states, and the inhomogeneous impurity-impurity interaction. The ionization energy of the substitutional impurity in the host lattice is found to be a deciding factor in this interaction. The internal and external absorption spectra of silicon doubly-doped with boron and indium acceptors is studied. The observed broadening of the boron external absorption lines in Si(B,In) is explained by neutral impurity scattering. The presence of indium in Si(B,In) crystal lattice, modifies the P₃⁄₂ valence band Bloch states and hence the configuration interaction. This modification is found responsible for the observed features of the boron 2p′ internal line in Si(B,In). The coupling between the lattice and the impurity bound carrier for deep monovalent acceptors in silicon, such as gallium and indium, is found to be stronger than for the shallow boron impurity. This suggests the possible existence of phonon-assisted transitions associated with these deep impurities. Such transitions are observed in the absorption spectrum of indium doped silicon. The phonon-assisted transitions are superimposed on the photoionization continuum transitions of the indium acceptors. Interference effects between the phonon-assisted transition and the transitions to the continuum states modify the position and line shape of the transitions. Using the phonon dispersion curves for silicon, interpretation of the results is presented. As a supplementary study, the temperature dependence of the indium external line 2, is investigated. The temperature dependence of halfwidth of indium line 2 in Si(In) supports the stronger electron-phonon coupling in Si(In).

 (University of Central Lancashire) Abstract: Indonesian Sign Language (Bahasa Isyarat Indonesia, or BISINDO) has been used since at least the 1950s, and was named in the 2000s. Since 2010, Nick has worked with local deaf people to create the BISINDO Corpus, with data from over 130 signers of different ages in six cities across the Indonesian archipelago. In this presentation, he will show and discuss five clips from the BISINDO Corpus to illustrate some of the findings of our analysis, along with some of the methodological challenges faced on the way. The presentation also features a contribution from his colleague Muhammad Isnaini, who is research co-ordinator at PUPET, the Indonesian Deaf Research Centre.
