description: We propose a new concept for a very low background multi-ton liquid xenon Dark Matter experiment. The detector consists of two concentric spheres and a charge readout device in the centre. Xenon between the two spheres forms a self-shield and veto device. The inner surface of the central sphere is coated with CsI to form an internal photocathode with minimum of 2πcoverage for any event in the active volume. Photoelectrons from the CsI photocathode drift toward the charge readout micro-structure in the centre of the detector. Both scintillation and ionisation are measured simultaneously for background rejection and 3-D event mapping. In addition to external shielding, the low background is achieved by eliminating PMTs and by using low radioactivity pure materials throughout the detector. We present detailed calculations of the charge readout system and design details. The detector is expected to probe the full SUSY parameter space.

description: Ceramic materials are ubiquitous in technologies operating under high mechanical, thermal or chemical constrains. Research in ceramic processing aims at creating ceramics with properties that are still challenging to obtain, such as toughness, transparency, conductivity, among others. Magnetic slip casting is a ceramic process where an external magnetic field is used to align the ceramic grains along preferential crystallographic directions, thereby creating controlled texture. Over the past 20 years of research on magnetic slip casting, ceramics of multiple chemistry were found to exhibit enhanced properties as a result from the texturation. This paper reviews the progress in the field of magnetic slip casting, details the processing parameters, the textures obtained for a diverse range of ceramic materials. The achieved mechanical and functional properties of the magnetically textured parts are presented. This overview of the magnetic slip casting process allows to identify critical directions for future advancement in advanced technical ceramics

description: An increasing number of researchers support reproducibility by including pointers to and descriptions of datasets, software and methods in their publications. However, scientific articles may be ambiguous, incomplete and difficult to process by automated systems. In this paper we introduce RO-Crate, an open, community-driven, and lightweight approach to packaging research artefacts along with their metadata in a machine readable manner. RO-Crate is based on Schema$.$org annotations in JSON-LD, aiming to establish best practices to formally describe metadata in an accessible and practical way for their use in a wide variety of situations. An RO-Crate is a structured archive of all the items that contributed to a research outcome, including their identifiers, provenance, relations and annotations. As a general purpose packaging approach for data and their metadata, RO-Crate is used across multiple areas, including bioinformatics, digital humanities and regulatory sciences. By applying "just enough" Linked Data standards, RO-Crate simplifies the process of making research outputs FAIR while also enhancing research reproducibility.

Finestre e finestrini: sguardi plurimi e incrociati sul “pays-temps” di Louis-Philippe Dalembert

description: The article focuses on the presence and the absence of windows, and specifically windows with shutters, car windows and rear-view mirrors in the novels by Haitian writer Louis-Philippe Dalembert. In his work, we can identify three tendencies. First of all, windows with shutters allow the passage from childhood to adulthood. Secondly, the absence of openings projects the character in heterotopias, which cause a language breakdown. Thirdly, the use of literary windows is linked with vagabondage and pays-temps. An image of the landscape is selected through a frame and we have the perception of a fragmentary vision. According to Dalembert, this world vision becomes a narrative element and a creative technique. This partial image which emerges from the symbolic space of the window allows us to talk about the childhood of the narrator from different perspectives: we can identify a geographical and temporal landscape (pays-temps) thanks to a reflection on the surface of the window and the possibility of remembering and imaging the past. Fiction is able to complete omissions, gaps, lapses.

description: We have performed an investigation of the nonlinear magnetic response in ruthenocuprates. A negative, diverging-like peak at the main magnetic transition T_N in RuSr2RECu2O8 (RE = Gd, Y) indicates a possible canted antiferromagnetic order. Another well defined feature above T_N points to a blocking of superparamagnetic particles through the T^(-3) dependence of the third harmonic at higher temperatures. Below T_N a nondiverging peak appears, which is strongly affected by the addition of 10% of Cu ions in the RuO2 planes. In RuSr2RE(2-x)Ce(x)Cu2O10 the main magnetic transition T_M is accompanied by two characteristic temperatures in the third harmonic of the ac susceptibility, in agreement with recent studies from uSR and Mossbauer spectroscopy. We find that the spin-spin correlation temperature is the same in both families of ruthenocuprates.

PELS Webinar Slides
Abstract: Power networks all over the world are experiencing dramatic upheaval in compositional form and anticipated functionality. With retirement of fossil-fuel-driven synchronous generators, integration of renewable energy, and adoption of electrified transportation, there is a pronounced change in the energy-conversion interfaces that form the backbone of the grid. Particularly, energy processing in future grids will be dominantly handled by semiconductor-based power-electronics circuits termed inverter-based resources (IBRs). This talk will provide snapshots of how classical power-system modeling problems can (and will have to) be revised to accommodate these emerging technologies. In particular, we will present insights on synchronization of IBRs with a variety of control methods, provide a system-theoretic solution to normalizing dynamic models of diverse grid assets, and overview a time-domain network-reduction method for large-scale electrical networks. Each topic will be presented with an effort to acknowledge the rich history of personalities, methods, and venues relevant to power engineering over the 20th century.

description: The objective of this study is to summarize the effects of surfactants on anaerobic digestion (AD) of waste activated sludge (WAS). The increasing amount of WAS has caused serious environmental problems. Anaerobic digestion, as the main treatment for WAS containing three stages (i.e. hydrolysis, acidogenesis, and methanogenesis), has been widely investigated. Surfactant addition has been demonstrated to improve the efficiency of AD. Surfactant, as an amphipathic substance, can enhance the efficiency of hydrolysis by separating large sludge and releasing the encapsulated hydrolase, providing more substance for subsequent acidogenesis. Afterwards, the short chain fatty acids (SCFAs), as the major product, have been produced. Previous investigations revealed that surfactant could affect the transformation of SCFA. They changed the types of acidification products by promoting changes in microbial activity and in the ratio of carbon to nitrogen (C/N), especially the ratio of acetic and propionic acid, which were applied for either the removal of nutrient or the production of polyhydroxyalkanoate (PHA). In addition, the activity of microorganisms can be affected by surfactant, which mainly leads to the activity changes of methanogens. Besides, the solubilization of surfactant will promote the solubility of contaminants in sludge, such as organic contaminants and heavy metals, by increasing the bioavailability or desorbing of the sludge.

description: In optoelectronic devices such as solar cells and photodetectors, a portion of electron-hole pairs are generated as so called hot carriers with an excess energy that is typically lost as heat. The long standing aim to harvest this excess energy to enhance device performance has proven to be very challenging, largely due to the extremely short-lived nature of hot carriers. Efforts thus focus on increasing the hot carrier relaxation time, and on tailoring heterostructures that allow for hot-carrier extraction on short time- and length-scales. Recently, semiconductor nanowires have emerged as a promising system to achieve these aims, because they offer unique opportunities for heterostructure engineering as well as for potentially modified phononic properties that can lead to increased relaxation times. In this review we assess the current state of theory and experiments relating to hot-carrier dynamics in nanowires, with a focus on hot-carrier photovoltaics. To provide a foundation, we begin with a brief overview of the fundamental processes involved in hot-carrier relaxation, and how these can be tailored and characterized in nanowires. We then analyze the advantages offered by nanowires as a system for hot-carrier devices and review the status of proof-of-principle experiments related to hot-carrier photovoltaics. To help interpret existing experiments on photocurrent extraction in nanowires we provide modelling based on non-equilibrium Green's functions. Finally, we identify open research questions that need to be answered in order to fully evaluate the potential nanowires offer towards achieving more efficient, hot-carrier based, optoelectronic devices.

description: In the present study, soot formation in the turbulent lifted diffusion flame, consisting of ethylene-air is numerically investigated using three different soot modeling approaches and is comprehensively reported. For turbulence-chemistry interaction, Flamelet generated manifold (FGM) model is used. A detailed kinetics is used which is represented through POLIMI mechanism (Ranzi et al. 2012). Soot formation is modeled using two different approaches, semi-empirical two-equation approach and Quadrature methods of moments approach, where both the approaches consider various sub-processes such as nucleation, coagulation, surface growth and oxidation. The radiation heat transfer is taken into account considering four fictitious gasses in conjunction with the weighted-sum-of-gray gas (WSSGM) approach for modeling absorption coefficient. The experimental and earlier published numerical data from Köhler et al. (2012) and Blacha et al. (2011) are used for assessment of different soot modeling approaches. The discrepancies between numerical and experimental data are observed due to under-prediction of OH radicals concentration and poor fuel-air mixing ratios in the vicinity of the fuel jet region leading to early soot formation and the trends are unaffected after invoking radiation.

description: Quantum networks using photonic channels require control of the interactions between the photons, carrying the information, and the elements comprising the nodes. In this work we theoretically analyse the spectral properties of an optical photon emitted by a solid-state quantum memory, which acts as a converter of a photon absorbed in another frequency range. We determine explicitly the expression connecting the stored and retrieved excitation taking into account possible mode and phase mismatch of the experimental setup. The expression we obtain describes the output field as a function of the input field for a transducer working over a wide range of frequencies, from optical-to-optical to microwave-to-optical. We apply this result to analyse the photon spectrum and the retrieval probability as a function of the optical depth for microwave-to-optical transduction. In the absence of losses, the efficiency of the solid-state quantum transducer is intrinsically determined by the capability of designing the retrieval process as the time-reversal of the storage dynamics.

description: We present the results of our identification of eight objects from a preliminary catalogue of X-ray sources detected in the 4-12 keV energy band by the Mikhail Pavlinsky ART-XC telescope aboard the SRG observatory during its first all-sky survey. Three of them (SRGAJ005751.0+210846,SRGAJ014157.0-032915, SRGAJ232446.8+440756) have been discovered by ART-XC, while five were already known previously as X-ray sources, but their nature remained unknown. The last five sources have also been detected in soft X-rays by the eROSITA telescope of the SRG observatory. Our optical observations were carried out at the 1.6-m AZT-33IK telescope of the Sayan Observatory and the 1.5-m Russian-Turkish telescope (RTT-150). All of the investigated objects have turned out to be active galactic nuclei (AGNs) at redshifts from 0.019 to 0.283. Six of them are Seyfert 2 galaxies(including one Seyfert 1.9 galaxy), one (SRGAJ005751.0+210846) is a "hidden" AGN (in an edge-on galaxy), and one (SRGAJ224125.9+760343) is a narrow-line Seyfert 1 galaxy. The latter object is characterized by a high X-ray luminosity (~(2-13)*10^44 erg/s in the 4-12 keV band) and,according to our black hole mass estimate (~2*10^7 M_sun), an accretion rate close to the Eddington limit. All three AGNs discovered by the ART-XC telescope (which are not detected by the eROSITA telescope) are characterized by a high absorption column density (N_H > 3*10^23 cm^-2). The results obtained confirm the expectations that the ART-XC telescope is an efficient instrument for searches of heavily obscured and other interesting AGNs in the nearby (z<0.3) Universe. The SRG all-sky survey will last for more than 3 years more, which will allow many such objects to be discovered.
Chaoticity Parameter Lambda in Hanbury-Brown Twiss Interferometry

description: In Hanbury-Brown-Twiss interferometry measurements using identical bosons, the chaoticity parameter lambda has been introduced phenomenologically to represent the momentum correlation function at zero relative momentum. It is useful to study an exactly solvable problem in which the lambda parameter and its dependence on the coherence properties of the boson system can be worked out in great detail. We are therefore motivated to study the state of a gas of noninteracting identical bosons at various temperatures held together in a harmonic oscillator potential that arises either externally or from bosons' own mean fields. We determine the degree of Bose-Einstein condensation and its momentum correlation function as a function of the attributes of the boson environment. The parameter lambda can then be evaluated from the momentum correlation function. We find that the lambda(p,T) parameter is a sensitive function of both the average pair momentum p and the temperature T, and the occurrence of lambda=1 is not a consistent measure of the absence of a coherent condensate fraction. In particular, for large values of p, the lambda parameter attains the value of unity even for significantly coherent systems with large condensate fractions. We find that if a pion system maintains a static equilibrium within its mean field, and if it contains a root-mean-squared radius, a pion number, and a temperature typical of those in high-energy heavy-ion collisions, then it will contain a large fraction of the Bose-Einstein pion condensate.

Electric utilities constantly deploy energy efficiency programs to achieve energy savings, minimize peak load, and make the gird more environmentally friendly. Voltage optimization (VO) is an energy efficiency measure that combines the technology of conservation voltage reduction (CVR) and Volt-Var Optimization (VVO) to deliver optimized voltage to customers and improve end-use efficiency. Studies have shown that deployment of CVR throughout the feeders in the U.S. can yield energy savings of 3.04% annually. This half-day tutorial will focus on VO implementation, innovation, deployment, and impacts. It is delivered by leading researchers and engineers who have worked on VO-related field implementation and research. Real utility practices on VO deployment and management, methodologies for assessing VO energy saving, along with the lessons learned from field experience will be presented and discussed.

description: To respond to the increasing need for bone repair strategies, various types of biomaterials have been developed. Among those, calcium phosphate ceramics (CPCs) are promising since they possess a chemical composition similar to that of bones. To be suitable for implants, CPCs need to fulfill a number of biological and mechanical requirements. Fatigue resistance and toughness are two key mechanical properties that are still challenging to obtain in CPCs. This paper thus reviews and discusses current progress in the processing of CPCs with bioinspired microstructures for load-bearing applications. First, methods to obtain CPCs with bioinspired structure at individual lengthscales, namely nano-, micro-, and macroscale are discussed. Then, approaches to attain synergetic contribution of all lengthscales through a complex and biomimetic hierarchical structure are reviewed. The processing methods and their design capabilities are presented and the mechanical properties of the materials they can produce are analysed. Their limitations and challenges are finally discussed to suggest new directions for the fabrication of biomimetic bone implants with satisfactory properties. The paper could help biomedical researchers, materials scientists and engineers to join forces to create the next generation of bone implants.

Increase in the interconnection of inverter-based resources around the world has brought about the need for grid forming (GFM) technology. However, the use of this technology for large-interconnected power networks is still an open field of research with many questions remaining open such as fault response, stability, and guarantee of grid-forming property. This tutorial will provide an overview of grid forming technology, and in-depth details regarding modeling, control, and stability analysis of GFM supported both by simulation and hardware results.

Reliable determination of vortex parameters from measurements of the microwave complex resistivity

description: We discuss and propose a complete data treatment, in close contact to typical microwave experimental data, in order to derive vortex parameters, such as pinning constant and viscous drag coefficient (also referred to as ``vortex viscosity''), in a way as model-independent as possible. We show that many of the accepted models for the complex resistivity can be described by a single, very general analytical expression. Using typical measurements of real and imaginary resistivity as a function of the applied field, we show that, even for single-frequency measurements, it is always possible to obtain (a) estimates of viscous drag coefficient and pinning constant with well-defined upper and lower bounds and (b) quantitative information about thermal creep. It turns out that neglecting thermal creep, in particular and counterintuitively at low temperatures, might result in a severe overestimation of the viscous drag coefficient. We also discuss the impact of thermal creep on the determination of the pinning constant. The present results might lead to a reconsideration of several estimates of the vortex parameters.

GREMLIN++ & BITGRAPH: IMPLEMENTING THE GREMLIN TRAVERSAL LANGUAGE AND A GPU-ACCELERATED GRAPH COMPUTING FRAMEWORK IN C++

description: This thesis consists of two major components, Gremlin++ and BitGraph. Gremlin++ is a C++ implementation of the Gremlin graph traversal language designed for interfacing with C++ graph processing backends. BitGraph is a graph backend written in C++ designed to outperform Java-based competitors, such as JanusGraph and Neo4j . It also offers GPU acceleration through OpenCL . Designing the two components of this thesis was a major undertaking that involved implementing the semantics of Gremlin in C++, and then writing the computing framework to execute Gremlin’s traversal steps in BitGraph, along with runtime optimizations and backend-specific steps. There were many important and novel design decisions made along the way, including some which yielded both advantages and disadvantages over Java-Gremlin. BitGraph was also compared to several major backends, including TinkerGraph, JanusGraph, and Neo4j. In this comparison, BitGraph offered the fastest overall runtime, primarily due to data ingest speedup.

description: (Abridged) We conduct a series of high-resolution, dissipationless N-body simulations to investigate the cumulative effect of substructure mergers onto thin disk galaxies in the context of the LCDM paradigm of structure formation. Our simulation campaign is based on a hybrid approach. Substructure properties are culled directly from cosmological simulations of galaxy-sized cold dark matter (CDM) halos. In contrast to what can be inferred from statistics of the present-day substructure populations, accretions of massive subhalos onto the central regions of host halos, where the galactic disk resides, since z~1 should be common occurrences. One host halo merger history is subsequently used to seed controlled numerical experiments of repeated satellite impacts on an initially-thin Milky Way-type disk galaxy. We show that these accretion events produce several distinctive observational signatures in the stellar disk including: a ring-like feature in the outskirts; a significant flare; a central bar; and faint filamentary structures that (spuriously) resemble tidal streams. The final distribution of disk stars exhibits a complex vertical structure that is well-described by a standard ``thin-thick'' disk decomposition. We conclude that satellite-disk encounters of the kind expected in LCDM models can induce morphological features in galactic disks that are similar to those being discovered in the Milky Way, M31, and in other disk galaxies. These results highlight the significant role of CDM substructure in setting the structure of disk galaxies and driving galaxy evolution. Upcoming galactic structure surveys and astrometric satellites may be able to distinguish between competing cosmological models by testing whether the detailed structure of galactic disks is as excited as predicted by the CDM paradigm.

description: Excerpts from the report Summary: Over 90 percent of the Ivory Coast population of about 3,400,000 is engaged in agriculture (including livestock raising) and forestry. In 1961, exports of chief farm products made up 75 percent of all exports. Considerable wood and wood products are exported. There is some manufacturing. Mining is of minor importance. For a relatively small country, the Ivory Coast has considerable diversity of agricultural production. Coffee exports furnish about 43 percent of the country's exports of all commodities, and cocoa exports nearly 21 percent. Other agricultural exports include bananas, kola nuts, pineapples, palm kernels, and fruit juices. The country's small cotton production is all spun and woven within the country. Chief domestic food crops include yams, plantains, cassava, rice, corn, and cocoyams. Coffee is the Ivory Coast's most valuable commodity, and also its biggest economic problem. Solving the problem of coffee surpluses is the major concern of the Government and its advisors. They also seek to diversify agriculture by increasing production of such commodities as rubber and cotton. They also wish to make the country more nearly self-sufficient in food by producing more rice and palm oil.
