description: Videos captured using Transmission Electron Microscopy (TEM) can encode details regarding the morphological and temporal evolution of a material by taking snapshots of the microstructure sequentially. However, manual analysis of such video is tedious, error-prone, unreliable, and prohibitively time-consuming if one wishes to analyze a significant fraction of frames for even videos of modest length. In this work, we developed an automated TEM video analysis system for microstructural features based on the advanced object detection model called YOLO and tested the system on an in-situ ion irradiation TEM video of dislocation loops formed in a FeCrAl alloy. The system provides analysis of features observed in TEM including both static and dynamic properties using the YOLO-based defect detection module coupled to a geometry analysis module and a dynamic tracking module. Results show that the system can achieve human comparable performance with an F1 score of 0.89 for fast, consistent, and scalable frame-level defect analysis. This result is obtained on a real but exceptionally clean and stable data set and more challenging data sets may not achieve this performance. The dynamic tracking also enabled evaluation of individual defect evolution like per defect growth rate at a fidelity never before achieved using common human analysis methods. Our work shows that automatically detecting and tracking interesting microstructures and properties contained in TEM videos is viable and opens new doors for evaluating materials dynamics.

description: Broyden's method, widely used in quantum chemistry electronic-structure calculations for the numerical solution of nonlinear equations in many variables, is applied in the context of the nuclear many-body problem. Examples include the unitary gas problem, the nuclear density functional theory with Skyrme functionals, and the nuclear coupled-cluster theory. The stability of the method, its ease of use, and its rapid convergence rates make Broyden's method a tool of choice for large-scale nuclear structure calculations.

description: The probability representation, in which cosmological quantum states are described by a standard positive probability distribution, is constructed for minisuperspace models selected by Noether symmetries. In such a case, the tomographic probability distribution provides the classical evolution for the models and can be considered an approach to select "observable" universes. Some specific examples, derived from Extended Theories of Gravity, are worked out. We discuss also how to connect tomograms, symmetries and cosmological parameters.

description: Carbon Nanotube (CNT) appears as a promising candidate to shrink field-effect transistors (FET) to the nanometer scale. Extensive experimental works have been performed recently to develop the appropriate technology and to explore DC characteristics of carbon nanotube field effect transistor (CNTFET). In this work, we present results of Monte Carlo simulation of a coaxially gated CNTFET including electron-phonon scattering. Our purpose is to present the intrinsic transport properties of such material through the evaluation of electron mean-free-path. To highlight the potential of high performance level of CNTFET, we then perform a study of DC characteristics and of the impact of capacitive effects. Finally, we compare the performance of CNTFET with that of Si nanowire MOSFET.

description: Electron microscopy is widely used to explore defects in crystal structures, but human detecting of defects is often time-consuming, error-prone, and unreliable, and is not scalable to large numbers of images or real-time analysis. In this work, we discuss the application of machine learning approaches to find the location and geometry of different defect clusters in irradiated steels. We show that a deep learning based Faster R-CNN analysis system has a performance comparable to human analysis with relatively small training data sets. This study proves the promising ability to apply deep learning to assist the development of automated microscopy data analysis even when multiple features are present and paves the way for fast, scalable, and reliable analysis systems for massive amounts of modern electron microscopy data.
Sign of tunnel coupling in barrier-separated Bose-Einstein condensates and stability of double-ring systems

description: We revisit recent claims about the instability of non-rotating tunnel coupled annular Bose-Einstein condensates leading to the emergence of angular-momentum Josephson oscillation [Phys. Rev. Lett. 98, 050401 (2007), arXiv:quant-ph/0609133v2]. It was predicted that all stationary states with uniform density become unstable in certain parameter regimes. By careful analysis, we arrive at a different conclusion. We show that there is a stable non-rotating and uniform ground state for any value of the tunnel coupling and repulsive interactions. The instability of an excited state with $π$ phase difference between the condensates can be interpreted in terms of the familiar snake instability. We further discuss the sign of the tunnel coupling through a separating barrier, which carries significance for the nature of the stationary states. It is found to always be negative for physical reasons.

$Nπ$-state contamination in lattice calculations of the nucleon electromagnetic form factors

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: The nucleon-pion-state contribution to QCD two-point and three-point functions relevant for lattice calculations of the nucleon electromagnetic form factors are studied in chiral perturbation theory. To leading order the results depend on a few experimentally known low-energy constants only, and the nucleon-pion-state contribution to the form factors can be estimated. The nucleon-pion-state contribution to the electric form factor $G_{\rm E}(Q^2)$ is at the +5 percent level for a source-sink separation of 2 fm, and it increases with increasing momentum transfer $Q^2$. For the magnetic form factor the nucleon-pion-state contribution leads to an underestimation of $G_{\rm M}(Q^2)$ by about 5 percent that decreases with increasing $Q^2$. For smaller source-sink separations that are accessible in present-day lattice simulations the impact is larger, although the ChPT results may not be applicable for such small time separations. Still, a comparison with lattice data at $t\approx 1.6$ fm works reasonably well.

description: In order to measure automatically the equivalent width of the Balmer lines in a database of 40,000 atmosphere models, we have developed a program that mimics the work of an astronomer in terms of identifying and eliminating secondary spectral lines mixed with the Balmer lines. The equivalent widths measured have average errors of 5 percent, which makes them very reliable. As part of the FITspec code, this program improves the automatic adjustment of an atmosphere model to the observed spectrum of a massive star.

description: An exact renormalization group for theories of a scalar chiral superfield is formulated, directly in four dimensional Euclidean space. By constructing a projector which isolates the superpotential from the full Wilsonian effective action, it is shown that the nonperturbative nonrenormalization theorem follows, quite simply, from the flow equation. Next, it is argued that there do not exist any physically acceptable non-trivial fixed points. Finally, the Wess-Zumino model is considered, as a low energy effective theory. Following an evaluation of the one and two loop beta-function coefficients, to illustrate the ease of use of the formalism, it is shown that the beta-function in the massless case does not receive any nonperturbative power corrections.

description: Light pulses entering an elongated bottle microresonator (BMR) from a transversely oriented input-output waveguide (microfiber) slowly propagate along the BMR length and bounce between turning points at its constricting edges. To avoid insertion losses and processing errors, a pulse should completely transfer from the waveguide into the BMR and, after being processed, completely return back into the waveguide. For this purpose, the waveguide and BMR should be impedance matched along the pulse bandwidth. Here we show how to enhance the impedance matched bandwidth by optimization of the BMR effective radius variation in a small vicinity of the input-output waveguide.

With large target masses and few keV recoil energy detection thresholds, neutral current coherent scattering of solar neutrinos becomes an irreducible background in dark matter searches. In the current zero-background analysis paradigm, neutrino coherent scattering will limit the achievable sensitivity to dark matter scattering cross sections, at the level of 10^{-46} cm^2.

description: It has been recently observed that the imposition of the $O(1,1)$ symmetry on the circle reduction of the classical effective action of string theory, can fix the effective action of the bosonic string theory at order $α'^2$, up to an overall factor. In this paper, we use the cosmological reduction on the action and show that, up to one-dimensional field redefinitions and total derivative terms, it can be written in the $O(25,25)$-invariant form proposed by Hohm and Zwiebach.

Use and utility of information channels for self-help advocacy groups
Creators: name: McCreary, Elaine Kathryn
Publisher: name: University of British Columbia
Year: 2010

description: In this study of self-help advocacy groups the research focused on how informal learners, as users of information, rate channels in society for their use and utility in the acquisition of functionally different kinds of information. A total of 105 respondents from 19 advocacy groups completed protocols. Data were submitted to conventional analyses for descriptive statistics using SPSS:9 and SPSS:X. Inferential statistics were calculated on a four-way, repeated measures, mixed effects analysis of variance using BMD-P8V. Intervening personal and group variables were tested for possible influence on the results. Results indicated that there was a core of multipurpose channels that were used a great deal, and a number of specialized channels that were each used only sparingly. Economic, environmental, and personal issue groups showed different emphases in their reported use of channels. Most channels received their highest rating for general background information. The pattern of user reports, as estimated by the analysis of variance main effects, reflected the structure of key variables. Two-way interactions were found to be significant between the channel categories and two other variables — types of information and kinds of user group.
title: Representations of Idomeneus in Graeco-Roman sources and their reception in the West, to 1720
Creators: name: McLaren, Colin Andrew
Publisher: name: University of St Andrews
Year: 2020

description: The dissertation examines representations of Idomeneus, and of the myths and traditions associated with him, in Graeco-Roman literature, and their reception in the West (represented by Italy, France, Germany and England). It takes the following form: Chapter 1, the representations and their cultural significance; Chapter 2, the representation of Idomeneus in the Iliad; Chapter 3, accretive representations of Idomeneus, principally from Late Antiquity; Chapter 4, the transmission of the accretive representations to the West, their accessibility through vernacular translation and their assimilation in contemporary literature; Chapter 5, the transmission of the Iliadic representation of Idomeneus to the West, through the publication of the epic, first in an academic format, latterly as polite literature; Chapter 6, the association of Iliadic and accretive representations in literature and drama between 1699 and 1720; Chapter 7, summary and conclusion. The dissertation addresses hitherto under-explored issues in the representation of Idomeneus. These include his limitations as an aristos in the Iliad; his gradual detachment from his associate, Meriones; his prominence in the English ‘interlude’, Horestes (1567); his treatment in Italian and French burlesque of the seventeenth and eighteenth centuries; his representation in fin-dix-septième French drama; and in Alexander Pope’s enlightened character study of 1720. These are supplemented by assessments of the impact of authorial/editorial omissions, paraphrases and interpolations on the representations; and of Idomeneus’ visibility in text, paratext and early ‘books of reference’, compared with that of his fellow-aristoi, the Aiantes, Diomedes, Nestor and Odysseus.

description: Three-dimensional topological insulators (TIs) are a perfectly tuned quantum-mechanical machinery in which counter-propagating and oppositely spin-polarized conduction channels balance each other on the surface of the material. This topological surface state crosses the bandgap of the TI, and lives at the interface between the topological and a trivial material, such as vacuum. Despite its balanced perfection, it is rather useless for any practical applications. Instead, it takes the breaking of time-reversal symmetry (TRS), and the appearance of an exchange gap to unlock hidden quantum states. The quantum anomalous Hall effect, which has first been observed in Cr-doped (Sb,Bi)$_2$Te$_3$, is an example of such a state in which two edge channels are formed at zero field, crossing the magnetic exchange gap. The breaking of TRS can be achieved by magnetic doping of the TI with transition metal or rare earth ions, modulation doping to keep the electronically active channel impurity free, or by proximity coupling to a magnetically ordered layer or substrate, in heterostructures or superlattices. We review the challenges these approaches are facing in the famous 3D TI (Sb,Bi)$_2$(Se,Te)$_3$ family, and try to answer the question whether these materials can live up to the hype surrounding them.

description: Using the example of the SU(2) gauge theory in 3+1 dimensions we consider the construction of a 3-dimensional effective model in terms of Polyakov loops. We demonstrate the application of an equilibrium self-consistency condition to the systematic analysis of the contribution of various (global Z(2) symmetric) terms in the effective model action. We apply this analysis to the construction of a simple effective action with the minimum necessary number of operators. Such an action is shown to be capable of reproducing relevant observables, e.g. the Polyakov loop ensemble average, within the desired accuracy.

description: The ever-growing need of data preservation and their systematic analysis contributing to sustainable development of the society spurred in the past decade,numerous Big Data projects and initiatives are focusing on the Earth Observation (EO). The number of Big Data EO applications has grown extremely worldwide almost simultaneously with other scientific and technological areas of the human knowledge due to the revolutionary technological progress in the space and information technology sciences. The substantial contribution to this development are the space programs of the renowned space agencies, such as NASA, ESA,Roskosmos, JAXA, DLR, INPE, ISRO, CNES etc. A snap-shot of the current Big Data sets from available satellite missions covering the Bulgarian territory is also presented. This short overview of the geoscience Big Data collection with a focus on EO will emphasize to the multiple Vs of EO in order to provide a snapshot on the current state-of-the-art in EO data preservation and manipulation. Main modern approaches for compressing, clustering and modelling EO in the geoinformation science for Big Data analysis, interpretation and visualization for a variety of applications are outlined. Special attention is paid to the contemporary EO data modelling and visualization systems.

Using the latest available astrophysical data, we redraw the Hillas plot and figure out potential UHECR accelerators. For the acceleration in central engines of active galactic nuclei, we constrain the maximal UHECR energy for a given black-hole mass. Among active galaxies, only the most powerful ones, radio galaxies and blazars, are able to accelerate protons to UHE, though acceleration of heavier nuclei is possible in much more abundant lower-power Seyfert galaxies.

Utility Business Case to Support Light Duty EV Charging
Creators: Benoit (Ben) Marcoux
Publisher: name: IEEE
Year: 2022

A white paper on Utility Business Case to Support Light Duty EV Charging
In this white paper, IEEE Smart Grid and its team of contributors offer some fact-based thoughts to power North American utilities’ push toward developing sound Electric Vehicle (EV) charging strategies, focusing here on light-duty passenger vehicles, such as cars and sport-utility vehicles. The bottom line is that, done right, EVs may prove to be good for these utilities and their ratepayers.

Inspired by the actions and results of some of North America’s leading utilities, we identified three value streams supporting the business case for utilities to support public EV charging in North America. First, research has shown that light-duty passenger EVs generally put downward pressure on electricity rates through increased demand requiring relatively little incremental investment, although the extent of this varies between utilities. Second, EV drivers are also prime targets for other utility programs (like energy efficiency) because they are among the most digitally engaged of all customers. Finally, leading utilities see new business opportunities from home, public and workplace charging.

However, for utilities to capture the value from the irreversible transition into EVs, they must develop new skills. As we will see, on the consumer side, EV drivers are dissatisfied by public charging, a barrier to adoption that increases range anxiety. Meanwhile, public charging stations are often not, by themselves, covering their costs, although they are essential for EV adoption. Furthermore, many utilities are driving blind through the transition — not even knowing when, how, or where charging occurs on their own electricity grid — or even who’s charging.
Unconventional elasticity in smectic-A elastomers

description: We study two aspects of the elasticity of smectic-$A$ elastomers that make these materials genuinely and qualitatively different from conventional uniaxial rubbers. Under strain applied parallel to the layer normal, monodomain smectic-$A$ elastomers exhibit a drastic change in Young's modulus above a threshold strain value of about 3%, as has been measured in experiments by Nishikawa and Finkelmann [Macromol. Chem. Phys. {\bf 200}, 312 (1999)]. Our theory predicts that such strains induce a transition to a smectic-$C$-like state and that it is this transition that causes the change in elastic modulus. We calculate the stress-strain behavior as well as the tilt of the smectic layers and the molecular orientation for strain along the layer normal, and we compare our findings with the experimental data. We also study the electroclinic effect in chiral smectic-$A^\ast$ elastomers. According to experiments by Lehmann {\em et al}. [Nature {\bf 410}, 447 (2001)] and Köhler {\em et al}. [Applied Physics A {\bf 80}, 381 (2003)], this effect leads in smectic-$A^\ast$ elastomers to a giant or, respectively, at least very large lateral electrostriction. Incorporating polarization into our theory, we calculate the height change of smectic-$A^\ast$ elastomer films in response to a lateral external electric field, and we compare this result to the experimental findings.

description: We present new Spitzer transit observations of four K2 transiting sub-Neptunes: K2-36c, K2-79b, K2-167b, and K2-212b. We derive updated orbital ephemerides and radii for these planets based on a joint analysis of the Spitzer, TESS, and K2 photometry. We use the EVEREST pipeline to provide improved K2 photometry, by detrending instrumental noise and K2's pointing jitter. We used a pixel level decorrelation method on the Spitzer observations to reduce instrumental systematic effects. We modeled the effect of possible blended eclipsing binaries, seeking to validate these planets via the achromaticity of the transits (K2 versus Spitzer). However, we find that Spitzer's signal-to-noise ratio for these small planets is insufficient to validate them via achromaticity. Nevertheless, by jointly fitting radii between K2 and Spitzer observations, we were able to independently confirm the K2 radius measurements. Due to the long time baseline between the K2 and Spitzer observations, we were also able to increase the precision of the orbital periods compared to K2 observations alone. The improvement is a factor of 3 for K2-36c, and more than an order of magnitude for the remaining planets. Considering possible JWST observations in 1/2023, previous 1 sigma uncertainties in transit times for these planets range from 74 to 434 minutes, but we have reduced them to the range of 8 to 23 minutes.

description: Problématique En Suisse, le taux de césarienne dépasse la recommandation fixée par l’Organisation Mondiale de la Santé. La pratique de l’accouchement par voie basse s’est dépopularisée, par l’influence des preuves scientifiques à ce sujet. Désormais, plusieurs alternatives sont proposées pour favoriser la version des fœtus en présentation podalique, notamment le recours aux médecines complémentaires. La sage-femme a donc un rôle primordial dans cette évolution. Pour ce faire, il semblerait que la stimulation du point d’acupuncture V67 ait fait ses preuves. Objectif L’objectif de cette revue de la littérature consiste à étudier la possibilité de promouvoir l’utilisation de la moxibustion, associée ou non à l’acupuncture, comme pratique efficace, afin de favoriser la version spontanée des fœtus en présentation podalique. Méthodologie Les bases de données Medline, CINAHL et MIDIRS ont été exploitées. Cette revue de la littérature se base sur l’analyse de cinq essais randomisés européens, datant de moins de 10 ans. Résultats L’analyse des articles sélectionnés met en lumière que les résultats ne sont pas statistiquement significatifs. Cependant, ils tendent à être en faveur de la moxibustion. On ne peut donc pas répondre clairement à la question de recherche. Conclusion En vue du manque d’homogénéité dans les études analysées, on ne peut en conclure un résultat flagrant. C’est pourquoi, il est nécessaire de poursuivre la recherche dans cette thématique.

description: We discuss the quantization in the minisuperspace for the generalized fourth-order teleparallel cosmological theory known as $f\left( T,B\right) $. Specifically we focus on the case where the theory is linear on the torsion scalar, in that consideration we are able to write the cosmological field equations with the use of a scalar field different from the scalar tensor theories, but with the same dynamical constraints as that of scalar tensor theories. We use the minisuperspace description to write for the first time the Wheeler-DeWitt equation. With the use of the theory of similarity transformations we are able to find exact solutions for the Wheeler-DeWitt equations as also to investigate the classical and semiclassical limit in the de Broglie -Bohm representation of quantum mechanics.

description: Avalanche photo detection is commonly used in applications which require single photon sensitivity. We examine the limits of using avalanche photo diodes (APD) for characterising photon statistics at high data rates. To identify the regime of linear APD operation we employ a ps-pulsed diode laser with variable repetition rates between 0.5MHz and 80MHz. We modify the mean optical power of the coherent pulses by applying different levels of well-calibrated attenuation. The linearity at high repetition rates is limited by the APD dead time and a non-linear response arises at higher photon-numbers due to multiphoton events. Assuming Poissonian input light statistics we ascertain the effective mean photon-number of the incident light with high accuracy. Time multiplexed detectors (TMD) allow to accomplish photon- number resolution by photon chopping. This detection setup extends the linear response function to higher photon-numbers and statistical methods may be used to compensate for non-linearity. We investigated this effect, compare it to the single APD case and show the validity of the convolution treatment in the TMD data analysis.

Material examined
INDIA • fossiliferous limestone at cliff section of Lakdi Nadi near Tera Village; Burdigalian, lower Miocene, Chhasra Formation; 23°22′19″ N, 68°58′10″ E; Jan.–Feb. 2012; Sonar leg.; GIS/B 0439.
Description
Colony erect biserial, branching. Autozooids club-shaped, arranged in alternate longitudinal rows (Fig. 3A). Cryptocyst barely developed, when present descending into opesia. Gymnocyst extended for ⅓ of frontal surface, occupied by ooecia of the proximal zooid if fertile (Fig. 3B). Opesia rounded to oval. Scutum not preserved. Distal oral spine bases stout, usually two internal, distal spine bases obscured by the ovicells (Fig. 3C). Lateral avicularia large, on outer distolateral corner of each autozooid, laterally directed, with acute rostrum, with somewhat raised tip. A frontal vibracula obliquely placed distolaterally with small rootlet foramen. Ooecia broad, conspicuous, slightly tilted away from axis of branch, ectooecium smooth, perforated by 12–15 unequal sized pseudopores.
Remarks
A single, weathered specimen was available to study, which does not allow to confirm the presence or details of a scutum or oral spine bases, the presence of frontal avicularia or axial vibracula. Hence, the species is left in open nomenclature until better preserved material is available. The present species differs from the Recent Indo-Pacific species Licornia diadema (Busk, 1852) in the absence of frontal avicularia, comparatively large lateral avicularia and the absence of a raised ooecial rim (see Vieira et al. 2013: 1914–1915, fig. 3e–f). The Recent south Pacific Australian species Licornia prolata Tilbrook & Vieira, 2012 differs in the presence of frontal avicularia, small lateral avicularia and the number of frontal pores on the ooecia.

description: The particle, string and membrane charge multiplets are derived in detail from the decomposition of the l1 (charge) representation of E(11) in three, four, five, six, seven and eight spacetime dimensions. A tension formula relating weights of the l1 (charge) representation of E(11) to the fundamental objects of M-theory and string theory is presented. The reliability of the formula is tested by reproducing the tensions of the content of the charge multiplets. The formula reproduces the masses for the pp-wave, M2, M5 and the KK-monopole from the low level content of the l1 representation of E(11). Furthermore the tensions of all the Dp-branes of IIA and IIB theories are found in the relevant decomposition of the l1 representation, with the string coupling constant and $α'$ appearing with the expected powers. The formula leads to a classification of all the exotic, KK-brane charges of M-theory.

colorectal cancer

description: Background: Colorectal cancer (CRC) is the third most common cause of cancer worldwide, up to 10% of cases are hereditary, and the remaining 90% are sporadic. Risk factors for the development of sporadic CRC are widely described; recently, the intestinal microbiome has been pointed out as an essential factor influencing the onset and development of CRC. Moreover, it has been described changes related to the taxonomy and functionality of the microbiome according to CRC stages, and specific taxa/function present or absent according to the progression of the disease. Modulation of the microbiome and the microbial metabolites implied in CRC progression would be of great interest. In this regard, precision nutrition interventions are of interest, considering that the microbiota could be modulated through diet and nutrients. Evidence suggests that dietary supplements could act as adjuvants in the treatment and management of cancer, but the possible modulatory effect over the microbiome of patients with CRC remains unexplored. Objective: We aim to study the metabolism signalling pathways interaction between microbiome and tumour cells in CRC, and the use of a bioactive compound derived from food phytochemicals to interfere with these pathways as an adjuvant treatment for CRC. Research strategy: Characterization of the microbial metabolome of patients with CRC based in public databases: We will evaluate previously published metagenomics datasets of oral (salivary) and gut (faecal) microbiomes to establish taxa composition, diversity, functional and metabolic changes related to CRC, taking into account the top-ranking features associated with CRC compared with healthy cohorts. Determine the relationship between oral and gut metagenome and their interaction with CRC: We will select a cohort of patients with still untreated CRC admitted to Infanta Sofia Hospital, that fulfils the criteria for participating in the Clinical trial for the treatment with the bioactive compound selected. Samples of saliva and faeces will be obtained at the time of CRC diagnosis after the beginning of the treatment, and at the time treatment ends, before the surgical procedure for removing the tumour. Samples will be analyzed by shotgun metagenomics to characterize the oral and gut microbiome. We will analyze the taxonomic and the metabolic profile of the samples. Evaluation of the modulatory effect of the bioactive compounds over the metabolic profile of the microbiota and the tumour progression: We will perform a metagenomics analysis of the samples obtained at the beginning and end of the treatment with the bioactive compound to evaluate shifts in microbiota function and composition. Moreover, we will assess the presence of the microbial biomarkers related to taxa and functionality described previously and monitor changes in those parameters after the treatment.

description: While experiments on fusion plasmas produce high-dimensional data time series with ever increasing magnitude and velocity, data analysis has been lagging behind this development. For example, many data analysis tasks are often performed in a manual, ad-hoc manner some time after an experiment. In this article we introduce the DELTA framework that facilitates near real-time streaming analysis of big and fast fusion data. By streaming measurement data from fusion experiments to a high-performance compute center, DELTA allows to perform demanding data analysis tasks in between plasma pulses. This article describe the modular and expandable software architecture of DELTA and presents performance benchmarks of its individual components as well as of entire workflows. Our focus is on the streaming analysis of ECEi data measured at KSTAR on NERSCs supercomputers and we routinely achieve data transfer rates of about 500 Megabyte per second. We show that a demanding turbulence analysis workload can be distributed among multiple GPUs and executes in under 5 minutes. We further discuss how DELTA uses modern database systems and container orchestration services to provide web-based real-time data visualization. For the case of ECEi data we demonstrate how data visualizations can be augmented with outputs from machine learning models. By providing session leaders and physics operators results of higher order data analysis using live visualization they may monitor the evolution of a long-pulse discharge in near real-time and may make more informed decision on how to configure the machine for the next shot.

description: Ab-initio calculations for the electronic and optical properties of single-layer (SL) tungsten disulfide (WS$_2$) in the presence of substitutional Erbium defects (Er$_{\rm W}$) are presented, where the W atom is replaced by an Er atom. Defects usually play an important role in tailoring electronic and optical properties of semiconductors. We show that neutral Er defects lead to localized defect states (LDS) in the band structure due to the f-orbital states of Er, which in turn give rise to sharp transitions in in-plane and out-of-plane optical absorption spectra, $α_{\parallel}$ and $α_{\perp}$. We identify the optical transitions at 3 $μ$m, 1.5 $μ$m, 1.2 $μ$m, 920 nm, 780 nm, 660 nm, and 550 nm to originate from Er$_{\rm W}$ defect states. In order to provide a clear description of the optical absorption spectra, we use group theory to derive the optical selection rules between LDS for both $α_{\parallel}$ and $α_{\perp}$.

Program planning as technology in three adult education units
Creators: name: Burnham, Byron Robert
Publisher: name: University of British Columbia
Year: 2010

description: This study examines program planning in adult education units in a school district, a community college and a university. Program planning is conceptualized as technology which is defined as activities undertaken to change program ideas into planned educational activities. This definition and a framework of three kinds of technology (long-linked, mediating, and intensive) and eight program planning activities allowed specific tasks performed by program planners to be examined for differences. The study was undertaken to determine if differences in program planning exist among units and if the concept of technology can be usefully employed in describing program planning. The case study method is employed in this investigation. Depth interviews with thirty individuals, organization reports, records, and publications contained data which were analyzed and used to describe the technology of each unit. Most interviews dealt with how programs were planned. They were tape recorded and conducted in two phases. Other interviews dealt with the relationships between the units and the organizations to which they belonged. The reports, records, and publications were used to help describe the organizational context of a unit and corroborate data from interviews. Program planning was accomplished in similar ways by individuals within a given unit. Degree of conformity varied among the units and technology was not a standard undertaking, although patterns of a technology were present in each unit. Individuals exhibited personal consistency more than they exhibited consistency in a unit. The historical or contextual setting of units influenced the pattern of technology employed. The investigator concludes that mixed technologies exist in the units and they are affected by unit purpose, leadership, and history. It was also concluded that integrating a unit with its organization was an important goal for unit and organizational heads and this goal also affected the kind of technology pattern used by unit.
