Slides for Webinar: Synergizing Clean Energy and Green Transportation
Sustainable development of cities and towns is expected to be considerably dependent on the use of clean energy and green transportation system with objectives for reducing pollution, minimizing congestion, improving efficiency, reliability, and quality. Innovations in energy conservation, energy efficiency, clean and renewable energy technologies along with smart grid, micro grid, smart meters, and the use of artificial intelligence have been reported worldwide. Autonomous electric vehicles and zero-emission green vehicles have started making inroads in metro and megacities. Therefore, synergizing innovations in clean energy and green transportation technology have a crucial role in transforming the sustainable connectivity of the future.  Such synergy can substantially improve air quality, environment, connectivity, and efficiency. This presentation highlights innovations in clean energy and green transportation technologies, policies, and practices for such transformation. Current trends, potential research & development projects, technology policy and governance issues which various stakeholders can collaborate on and how youths can be engaged in inspiring and enriching such programmes will, also, be discussed.
Correction to Relativistic Mean Field binding energy and $N_pN_n$ scheme

description: The differences between the experimental and Relativistic Mean Field binding energies have been calculated for a large number of even-even nuclei from A=50 to 220. Excluding certain mass regions, the differences, after suitable corrections for particular isotope chains, are found to be proportional to the Casten factor $P$, chosen as a measure of n-p interaction strength in a nucleus. Results for even-$Z$ odd-$N$ nuclei are also seen to follow the same relation, if the odd-even mass difference is taken into account following the semiempirical formula. This indicates that the n-p interaction is the major contributor to the difference between the calculated and the experimental binding energies.

Prospects for the direct detection of neutralino dark matter in orbifold scenarios

description: We analyse the phenomenology of orbifold scenarios from the heterotic superstring, and the resulting theoretical predictions for the direct detection of neutralino dark matter. In particular, we study the parameter space of these constructions, computing the low-energy spectrum and taking into account the most recent experimental and astrophysical constraints, as well as imposing the absence of dangerous charge and colour breaking minima. In the remaining allowed regions the spin-independent part of the neutralino-proton cross section is calculated and compared with the sensitivity of dark matter detectors. In addition to the usual non universalities of the soft terms in orbifold scenarios due to the modular weight dependence, we also consider D-term contributions to scalar masses. These are generated by the presence of an anomalous U(1), providing more flexibility in the resulting soft terms, and are crucial in order to avoid charge and colour breaking minima. Thanks to the D-term contribution, large neutralino detection cross sections can be found, within the reach of projected dark matter detectors.

description: We report a layered ternary selenide BaPt4Se6 featuring sesqui-selenide Pt2Se3 layers sandwiched by Ba atoms. The Pt2Se3 layers in this compound can be derived from the Dirac-semimetal PtSe2 phase with Se vacancies that form a honeycomb structure. This structure results in a Pt (VI) and Pt (II) mixed-valence compound with both PtSe6 octahedra and PtSe4 square net coordination configurations. Temperature dependent electrical transport measurements suggest two distinct anomalies: a resistivity crossover, mimic to the metal-insulator (M-I) transition at ~150K, and a resistivity plateau at temperatures below 10K. The resistivity crossover is not associated with any structural, magnetic or charge order modulated phase transitions. Magnetoresistivity, Hall and heat capacity measurements concurrently suggest an existing hidden state below 5K in this system. Angle-resolved photoemission spectroscopy measurements reveal a metallic state and no dramatic reconstruction of the electronic structure up to 200K.

description: We discuss the measurements of the galaxy cluster mass functions at z=~0.05 and z=~0.5 using high-quality Chandra observations of samples derived from the ROSAT PSPC All-Sky and 400deg^2 surveys. We provide a full reference for the data analysis procedures, present updated calibration of relations between the total cluster mass and its X-ray indicators (T_X, Mgas, and Y_X) based on a subsample of low-z relaxed clusters, and present a first measurement of the evolving L_X-Mtot relation (with Mtot estimated from Y_X) obtained from a well-defined statistically complete cluster sample and with appropriate corrections for the Malmquist bias applied. Finally, we present the derived cluster mass functions, estimate the systematic uncertainties in this measurement, and discuss the calculation of the likelihood function. We confidently measure the evolution in the cluster comoving number density at a fixed mass threshold, e.g., by a factor of 5.0 +- 1.2 at M_500=2.5e14 h^-1 Msun between z=0 and 0.5. This evolution reflects the growth of density perturbations and can be used for the cosmological constraints complementing those from the distance-redshift relation.

description: It is shown that the low energy coefficients of the next-to-leading order (NLO) chiral perturbation theory needed to determine $ΔI=1/2$, $K\toππ$ decay amplitudes can be fixed by calculating $Kπ\toπ$ amplitudes on lattice. Unlike using NLO $K\toππ$ amplitudes proposed by Laiho and Soni, simulating $Kπ\toπ$ transitions on lattice does not require evaluations of s-channel disconnected diagrams which have been an obstacle in practice.

Química Geral

description: RESUMO As inúmeras dificuldades ensino-aprendizagem do conteúdo de ligações químicas no ensino superior (destacam-se na literatura os problemas de representação, a visão compartimentada dos tipos de ligações e a falta de relação com propriedades físico-químicas dos materiais) deixam clara a necessidade de atividades voltadas para melhoria desse cenário. Por abranger muitos desses itens em seus fundamentos, a Cristaloquímica é uma área que pode muito bem ser explorada. Desse modo, o objetivo principal deste trabalho envolve a elaboração e a avaliação de atividades envolvendo cristaloquímica para disciplinas de Química Geral da UNIFESP – Campus Diadema visando a aprendizagem do conceito de ligações químicas. A avaliação está sendo realizada com base nas atividades entregues pelos discentes e terá um viés qualitativo (empregando a análise textual discursiva) e quantitativo (a partir da escolha do método estatístico apropriado à amostra). Partindo da premissa de uma aprendizagem em espiral, a cristaloquímica está sendo revisitada em diferentes conteúdos de uma mesma disciplina - também está previsto a retomada desse tema em disciplinas sequenciais. A aplicação da pesquisa iniciou-se com a disciplina de Fundamentos de Química Geral 01 do curso de Ciências Ambientais mediante o uso de simulações virtuais com os softwares Crystalwalk e PhET Interative Simulations. Além do conteúdo de ligações químicas, a cristaloquímica também foi discutida durante os conteúdos de dispersões (hidratação de íons e/ou moléculas) e funções inorgânicas (estruturas cristalinas). Apesar do levantamento feito no início da referida disciplina ter evidenciado um significativo desconhecimento de conceitos básicos da mineralogia e cristalografia - e também da própria química -, as simulações virtuais têm se mostrado eficientes em uma aproximação com os conceitos de cela unitária, estrutura cristalina e caráter percentual de uma ligação química.

description: Detailed spectropolarimetric studies may hold the key to probing the explosion mechanisms and the progenitor scenarios of Type Ia supernovae (SNe Ia). We present multi-epoch spectropolarimetry and imaging polarimetry of SN 2019ein, an SN Ia showing high expansion velocities at early phases. The spectropolarimetry sequence spans from $\sim -11$ to $+$10 days relative to peak brightness in the $B$-band. We find that the level of the continuum polarization of SN 2019ein, after subtracting estimated interstellar polarization, is in the range $0.0-0.3\%$, typical for SNe Ia. The polarization position angle remains roughly constant before and after the SN light-curve peak, implying that the inner regions share the same axisymmetry as the outer layers. We observe high polarization ($\sim 1\%$) across both the Si II $\lambda6355$ and Ca II near-infrared triplet features. These two lines also display complex polarization modulations. The spectropolarimetric properties of SN 2019ein rule out a significant departure from spherical symmetry of the ejecta for up to a month after the explosion. These observations disfavour merger-induced and double-detonation models for SN 2019ein. The imaging polarimetry shows weak evidence for a modest increase in polarization after $\sim 20$ days since the $B$-band maximum. If this rise is real and is observed in other SNe Ia at similar phases, we may have seen, for the first time, an aspherical interior similar to what has been previously observed for SNe IIP. Future polarization observations of SNe Ia extending to post-peak epochs will help to examine the inner structure of the explosion.

description: Aims: We present a quantitative study of a new data set of high redshift Type Ia supernovae spectra, observed at the Gemini telescopes during the first 34 months of the Supernova Legacy Survey. During this time 123 supernovae candidates were observed, of which 87 have been identified as SNe Ia at a median redshift of z=0.720. Spectra from the entire second year of the survey and part of the third year (59 total SNe candidates with 46 confirmed SNe Ia) are published here for the first time. The spectroscopic measurements made on this data set are used determine if these distant SNe comprise a population similar to those observed locally. Methods: Rest-frame equivalent width and ejection velocity measurements are made on four spectroscopic features. Corresponding measurements are presented for a set of 167 spectra from 24 low-z SNe Ia from the literature. Results: We show that there exists a sample at high redshift with properties similar to nearby SNe. No significant difference was found between the distributions of measurements at low and high redsift for three of the features. The fourth feature displays a possible difference that should be investigated further. Correlations between Type Ia SNe properties and host galaxy morphology were also found to be similar at low and high z, and within each host galaxy class we see no evidence for redshift-evolution in SN properties. A new correlation between SNe Ia peak magnitude and the equivalent width of SiII absorption is presented. We demonstrate that this correlation reduces the scatter in SNe Ia luminosity distances in a manner consistent with the lightcurve shape-luminosity corrections that are used for Type Ia SNe cosmology. Conclusions: We show that this new sample of SNLS SNe Ia has spectroscopic properties similar to nearby objects. (Abridged)

description: Το σύνδρομο Birt-Hogg-Dubé είναι μια σπάνια γενετική διαταραχή που κληρονομείται με αυτοσωματικό επικρατή χαρακτήρα. Προκαλείται από μεταλλάξεις στο γονίδιο FLCN και συνήθως εκδηλώνεται κλινικά από την 3η δεκαετία ζωής. Χαρακτηρίζεται από πολλαπλά ινοθυλακώματα, τριχοδισκώματα και ακροχόρδωνες, που εκδηλώνονται ως ασυμπτωματικές βλατίδες στο χρώμα του δέρματος, διαμέτρου 2-4 mm και εντοπίζονται στο κεφάλι, την τραχηλική περιοχή και τον άνω κορμό. Δερματοσκοπικά χαρακτηρίζονται από λευκές βλατίδες/σφαιρίδια με κεντρική κιτρινωπή/καφέ κηλίδα. Οι ασθενείς με αυτό το σύνδρομο αναπτύσσουν συχνά πνευμονικές κύστεις και πνευμοθώρακα και έχουν αυξημένο κίνδυνο εμφάνισης καρκίνου του νεφρού και του παχέος εντέρου. Η έγκαιρη διάγνωση του συνδρόμου με τη συνδρομή της δερματοσκόπησης είναι πολύ σημαντική.
description: Birt-Hogg-Dubé syndrome is a rare genetic disorder that is inherited in an autosomal dominant manner. It is caused by mutations in the FLCN gene and usually manifests clinically from the 3rd decade of life. It is characterized by multiple fibrofolliculomas, trichodiscomas, and acrochordons, which manifest as asymptomatic skin-colored papules, 2-4 mm in diameter, located on the head, cervical region, and upper trunk. In dermoscopy they are characterized by white papules/globules with a central yellowish/brown spot. Patients with this syndrome often develop lung cysts and pneumothorax and have an increased risk of kidney and colon cancer. Early diagnosis of the syndrome with the help of dermοscopy is very important.

description:
Female sex workers (FSWs) living with HIV are a vulnerable population for multiple health concerns and have been vastly understudied in public health literature. This study analyzes factors related to pregnancy among 268 FSWs living with HIV in the Dominican Republic. Results indicate that 34 % of participants had been pregnant since HIV diagnosis. Multivariate analysis revealed significant associations between pregnancy after HIV diagnosis and ART interruption (AOR 2.41; 95 % CI 1.19, 4.94), knowledge of mother-to-child transmission (AOR 2.12; 95 % CI 0.99, 4.55), serostatus disclosure to a sex partner (AOR 2.46; 95 % CI 1.31, 4.62), older age (AOR 0.91; 95 % CI 0.87, 0.95) and a more negative perception of their health provider (AOR 0.56; 95 % CI 0.34, 0.93). Results indicate noteworthy associations between having been pregnant and the health provider experience and ART interruption, indicating a significant need for further research on this population to ensure both maternal and child health.

description: The aim of our study was to evaluate all-cause mortality risk in patients with laboratory-confirmed COVID-19 in Mexico City treated with repurposed antivirals and antibiotics. This real-world retrospective cohort study contemplated 395,343 patients evaluated for suspected COVID-19 between February 24 and September 14, 2020 in 688 primary-to-tertiary medical units in Mexico City. Patients were included with a positive RT-PCR for SARS-CoV-2; those receiving unspecified antivirals, excluded; and groups of antivirals prescribed in < 30 patients, eliminated. Survival and mortality risks were determined for patients receiving antivirals, antibiotics, both, or none. We assessed the effect of early (<2 days) versus late (>2 days) use of antivirals on mortality in a sub-cohort of patients. Multivariable adjustment, propensity score matching, generalized estimating equations, and calculation of E-values were performed to limit confounding. 136,855 patients were analyzed; mean age 44.2 (SD:16.8) years; 51.3 % were men. 16.6 % received antivirals (3 %), antibiotics (10 %), or both (3.6 %). Antivirals studied were Oseltamivir (n=8414), Amantadine (n=319), Lopinavir-Ritonavir (n=100), Rimantadine (n=61), Zanamivir (n=39), and Acyclovir (n=36). Survival with antivirals (73.7 %, p<0.0001) and antibiotics (85.8 %, p<0.0001) was lower than no antiviral/antibiotic (93.6 %). After multivariable adjustment, increased risk of death occurred with antivirals (HR=1.72, 95 % CI: 1.61-1.84) in ambulatory (HR=4.7, 95 % CI: 3.94-5.62) and non-critical (HR=2.03, 95 % CI: 1.86-2.21) patients. Oseltamivir increased mortality risk in the general population (HR=1.72, 95 % CI: 1.61-1.84), ambulatory (HR=4.79, 95 % CI: 4.01-5.75), non-critical (HR=2.05, 95 % CI: 1.88-2.23), and pregnancy (HR=8.35, 95 % CI: 1.77-39.30); as well as hospitalized (HR=1.13, 95 % CI: 1.01-1.26) and critical patients (HR=1.22, 95 % CI: 1.05-1.43) after propensity score-matching. Early versus late oseltamivir did not modify the risk. Antibiotics were a risk factor in general population (HR=1.13, 95 % CI: 1.08-1.19) and pediatrics (HR=4.22, 95 % CI: 2.01-8.86), but a protective factor in hospitalized (HR=0.81, 95 % CI: 0.77-0.86) and critical patients (HR=0.67, 95 % CI: 0.63-0.72). No significant benefit for repurposed antivirals was observed; oseltamivir was associated with increased mortality. Antibiotics increased mortality risk in the general population but may increase survival in hospitalized and critical patients.

Origin of dwarf irregular galaxies with outer early-type structures
Creators: name: Bekki, Kenji
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent observations have reported that some gas-rich dwarf irregular (dIrr) galaxies appear to have spherical distributions in the outer underlying old and intermediate-age stellar populations (e.g., NGC 6822). These observations imply that some dIrr's have two distinct (or ``two-component'') structures, i.e., inner disky and outer spherical ones, though the number fraction of dIrr's with such structures remains observationally unclear. We discuss how such two distinct structures are formed during dIrr formation based on observations and simulations. Our numerical simulations show that the remnants of mergers between two gas-rich dIrr's with initially extended gas disks can have both extended spheroids composed of older stellar populations and disks composed mostly of gas and young stars. The simulated remnants with two distinct structures can be still identified as dIrr's owing to the presence of star-forming regions. The structural properties of outer spherical structures in dIrr's formed from dIrr-dIrr merging depend on initial conditions of merging, which suggests that outer structures in dIrr's can be diverse. We also discuss other possible physical mechanisms for the formation of outer spherical structures composed of older stars in dIrr's.

description: The higher Sugawara operators acting on the Verma modules over the affine Kac-Moody algebra at the critical level are related to the higher Hamiltonians of the Gaudin model due to work of Feigin, Frenkel and Reshetikhin. An explicit construction of the higher Hamiltonians in the case of gl_n was given recently by Talalaev. We propose a new approach to these results from the viewpoint of the vertex algebra theory by proving directly the formulas for the higher order Sugawara operators. The eigenvalues of the operators in the Wakimoto modules of critical level are also calculated.

description: My research Perspective is Moving started with two questions. An internal one - how do I see the world? And a professional facing one - how can a design or design process contribute to shifting contemporary dualist, human-centered perspectives derived from modernity to ones that are more relational, pluriversal, and ecological? My research is a personal journey, to ponder how it is that I have been tamed by modern society, to mark out how I have adapted to these constraints and to find alternative approaches to counter them. As a way to shift my own perspective and assumption of the design process, I have applied epistemic artefacts found in modern world to my own process of cognitive recognition: Seeing-Refusing-Doing-Engaging-Embodying-Knowing-Becoming. Reflections at the end of each of these stages enabled me to identify my next steps. Generative, they became my way of finding a way forward. My early stages of research were developed through a cognitive design practice made up of actions for: Relating, Transposing, Merging, and Turning. In the second stage of my inquiry I embraced an empirical design practice made of actions that were: Engaging and Embodying. Outcomes from the early stages of my research trajectory show how flexibility and connectivity of my perspective and relationships can affect the process of designing artefacts. The second stage of my work demonstrates how I sought out ways to negotiate and communicate with nature. A specific tree, located in the public park of Vancouver plays an important role in this stage of my work – a way of connecting with nature. My work, detailed in this thesis document, provides other designers provocative tactics to think about how we live and be with nature and concurrently contribute through our work as designers. It is also an invitation to designers with limited first hand experiences in nature or ecological thinking: observe how my perspective has changed by trying the approaches and methods that I took on.

description: The combination of two-dimensional (2D) materials into vertical heterostructures has emerged as a promising path to designer quantum materials with exotic properties. Here, we extend this concept from inorganic 2D materials to 2D metal-organic frameworks (MOFs) that offer additional flexibility in realizing designer heterostructures. We successfully fabricate a monolayer 2D Cu-dicyanoanthracene MOF on a 2D van der Waals NbSe$_2$ superconducting substrate. The structural and electronic properties of two different phases of the 2D MOF are characterized by low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS), complemented by density-functional theory (DFT) calculations. These experiments allow us to follow the formation of the kagome bandstructure from Star of David -shaped building blocks. This work extends the synthesis and electronic tuneability of 2D MOFs beyond the electronically less relevant metal and semiconducting surfaces to superconducting substrates, which are needed for the development of emerging quantum materials such as topological superconductors.

On the Magnetic Prandtl Number Behavior of Accretion Disks

Publisher: name: arXiv
Year: 2007

description: We investigate the behavior of the magnetic Prandtl number (ratio of microscopic viscosity to resistivity) for accretion sources. Generally this number is very small in standard accretion disk models, but can become larger than unity within $\sim 50$ Schwarzschild radii of the central mass. Recent numerical investigations suggest a marked dependence of the level of MHD turbulence on the value of the Prandtl number. Hence, black hole and neutron star accretors, i.e. compact X-ray sources, are affected. The astrophysical consequences of this could be significant, including a possible route to understanding the mysterious state changes that have long characterized these sources.

Properties of Local Quantum Operations with Shared Entanglement

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Multi-party local quantum operations with shared quantum entanglement or shared classical randomness are studied. The following facts are established: (i) There is a ball of local operations with shared randomness lying within the space spanned by the no-signaling operations and centred at the completely noisy channel. (ii) The existence of the ball of local operations with shared randomness is employed to prove that the weak membership problem for local operations with shared entanglement is strongly NP-hard. (iii) Local operations with shared entanglement are characterized in terms of linear functionals that are ``completely'' positive on a certain cone K of separable Hermitian operators, under a natural notion of complete positivity appropriate to that cone. Local operations with shared randomness (but not entanglement) are also characterized in terms of linear functionals that are merely positive on that same cone K. (iv) Existing characterizations of no-signaling operations are generalized to the multi-party setting and recast in terms of the Choi-Jamiolkowski representation for quantum super-operators. It is noted that the standard nonlocal box is an example of a no-signaling operation that is separable, yet cannot be implemented by local operations with shared entanglement.

description: There is a consensus that turbulence-free images cannot be obtained by conventional computational ghost imaging (CGI) because the CGI is only a classic simulation, which does not satisfy the conditions of turbulence-free imaging. In this article, we first report a turbulence-immune CGI method based on a multi-scale generative adversarial network (MsGAN). Here, the conventional CGI framework is not changed, but the conventional CGI coincidence measurement algorithm is optimized by an MsGAN. Thus, the satisfactory turbulence-free ghost image can be reconstructed by training the network, and the visual effect can be significantly improved.

Systematic Relationships of Power Converter Topologies through Graph Theory-Slides

PELS Webinar Slides
Abstract: Entering the 21st century, new technologies and theories are entering the paradigm of power electronics, leading to increasing diversity of the field. As the research volume of power converter increasing fast, resemble circuits and similar operation methods are emerging in recent decades, and needed to be reorganized and studied systematically. Therefore, it could be beneficial to establish the fundamental relationships among various power converters topologies, and to link different converters with universal principles. The electrical duality has been well acknowledged when dealing with such circuit-level unifications. Meanwhile, the graphical isomorphism also shows some great potential for topology derivations and modulation innovations. Furthermore, by synergistically implementation of these two theories, the topology transformation rules can be implemented for power converters. With such relationships, the derived topology or modulations can be generalized for other topologies, therefore, further reduce the design burden and accelerate the research process. In this webinar, the basic concepts of graph theory will be introduced, followed by the discussion and demonstrations of electrical dual principles and emerging isomorphic theory for various power converters, in particular, the voltage-source converters and current-source converters. The unique cycling phenomenon of topology transformation will also be investigated. Finally, the webinar ends with discussions and further research trends in this area.
Dynamical Casimir effect for magnons in a spinor Bose-Einstein condensate

description: Magnon excitation in a spinor Bose-Einstein condensate by a driven magnetic field is shown to have a close analogy with the dynamical Casimir effect. A time-dependent external magnetic field amplifies quantum fluctuations in the magnetic ground state of the condensate, leading to magnetization of the system. The magnetization occurs in a direction perpendicular to the magnetic field breaking the rotation symmetry. This phenomenon is numerically demonstrated and the excited quantum field is shown to be squeezed.

description: The polarization sensitivity of the upcoming millimetric observatories will open new possibilities for studying the properties of galaxy clusters and for using them as powerful cosmological probes. For this reason it is necessary to investigate in detail the characteristics of the polarization signals produced by their highly ionized intra-cluster medium (ICM). This work is focussed on the polarization effect induced by the ICM bulk motions, the so-called kpSZ signal, which has an amplitude proportional to the optical depth and to the square of the tangential velocity. In particular we study how this polarization signal is affected by the internal dynamics of galaxy clusters and what is its dependence on the physical modelling adopted to describe the baryonic component. This is done by producing realistic kpSZ maps starting from the outputs of two different sets of high-resolution hydrodynamical N-body simulations. The first set (17 objects) follows only non-radiative hydrodynamics, while for each of 9 objects of the second set we implement four different kinds of physical processes. Our results shows that the kpSZ signal turns out to be a very sensitive probe of the dynamical status of galaxy clusters. We find that major merger events can amplify the signal up to one order of magnitude with respect to relaxed clusters, reaching amplitude up to about 100 nuK. This result implies that the internal ICM dynamics must be taken into account when evaluating this signal because simplicistic models, based on spherical rigid bodies, may provide wrong estimates. Finally we find that the dependence on the physical modelling of the baryonic component is relevant only in the very inner regions of clusters.

Extinction in the Large Magellanic Cloud Bar around NGC1854, NGC1856, and NGC1858

description: We report on the extinction properties in the fields around the clusters NGC 1854, NGC 1856, and NGC 1858 in the bar of the Large Magellanic Cloud. The colour-magnitude diagrams of the stars in all these regions show an elongated red giant clump that reveals a variable amount of extinction across these fields, ranging from Av~0.2 to Av~1.9, including Galactic foreground extinction. The extinction properties nonetheless are remarkably uniform. The slope of the reddening vectors measured in the (V-I,V) and (B-I,B) colour-magnitude planes is fully in line with the Av/E(B-V)~5.5 value found in the outskirts of 30 Dor. This indicates the presence of an additional grey extinction component in the optical requiring big grains to be about twice as abundant as in the diffuse Galactic interstellar medium (ISM). Areas of higher extinction appear to be systematically associated with regions of more intense star formation, as measured by the larger number of stars more massive than 8 Msun, thus making injection of big grains into the ISM by SNII explosion the likely mechanism at the origin of the observed grey extinction component.

Laying the Groundwork for Creating Utility Analytics Session 2: OT, Analytics and Data (Slides)
Creators: Doug Houseman
Publisher: name: IEEE
Year: 2021

Utility analytics do not start with buying an analytic package and hiring a data scientist or two. Instead, they start in the field with the decisions on what data to capture, how much of it is transmitted, where it is processed and storage. Relays and other sensing equipment in the field have many inputs, and some are only connected to a few of these inputs, meaning data is not possible to capture, should those inputs be connected? How do you create a simple diagram that allows the discussion of the inputs and their value? Why are field walk downs needed and what can I do about fixing my topology in my systems – which is the basic requirement for most analytics?
Once the right field data is flowing into the enterprise, what do I do with it, and why can’t I just drop it into an analytics package or an AI system and be done with it? What do you mean there is hard work between raw data and actionable analytics? What are the hard won lessons of real insight?

description: Stellar jets are normally constituted by chains of knots with some periodicity in their spatial distribution, corresponding to a variability of order of several years in the ejection from the protostar/disk system. A widely accepted theory for the presence of knots is related to the generation of internal working surfaces due to variations in the jet ejection velocity. In this paper we study the effect of variations in the inner disk-wind radius on the jet ejection velocity. We show that a small variation in the inner disk-wind radius produce a variation in the jet velocity large enough to generate the observed knots. We also show that the variation in the inner radius may be related to a variation of the stellar magnetic field.
