description: Are journalists and Facebook users equally interested in political news? Introducing the conceptualization and measurement of the “news sharing gap”, this study compares the sharing of political news by Facebook users to the production of political news by news media organizations. To paint a broad picture of these differences, we compare the news sharing gap (a) across election and routine periods and (b) across eight countries: Australia, Austria, Brazil, Germany, the Netherlands, Romania, Spain, and the United Kingdom. Analyzing 265,714 articles shared over 12 million times on Facebook, findings show that elections are broadly linked to increases in political news publication, but even larger increases in political news sharing. The study reveals how, overall, political news is shared more often than news publication patterns would suggest, proposing higher political interest by Facebook users than previously thought. In most cases, political news sharing far outpaces political news production in the form of a “negative” news sharing gap, with the relative demand for political news (in the form of news sharing) being higher than the supply. Lastly, building upon previous work, we propose and validate a distant supervised machine learning method for multilingual, large-scale identification of political news across distinct languages, contexts and time periods.

Effect of extrusion cooking on some quality attributes of full-fat soy flour and soy protein concentrate from locally grown Soybean (Glycine Max L.) varieties
Creators: name: Muhsin, Fouzia
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: Soybean (Glycine max L.) varieties, Clark 63K and SCS1 were obtained from Jimma Agricultural Research Center. Their seed color and shape, seed density; hundred seed mass, hydration and swelling capacities, hydration and swelling indices, hydration and swelling coefficients were studied according to the standard procedures. The seeds were processed and converted into full fat soy flour (FFSF) and soy protein concentrate (FF-SPC) to study the effect of extrusion. The flours and concentrates from each variety were extruded at a barrel temperature of 140 0C, screw speed of 120rpm, and feed moisture of 30%. The effect on extrudates expansion ratio, specific length, proximate composition, flour and extrudate bulk density (BD), water absorption index (WAI), water solubility index (WSI), oil absorption capacity (OAC), emulsion activity (EA) and stability (ES), foaming capacity (FC) and stability (FS) was studied in triplicate samples. The result of the seed analysis of both varieties showed no statistical significant difference except in swelling coefficient. The bulk density of FFSF is significantly higher than that of FF-SPC flour, while FFSF extrudates have lower bulk density than that of the unprocessed flour. WAI of FF-SPC flour and extrudates of both varieties were found to be significantly higher than that of FFSF. WSI of FFSF flour and extrudates of both varieties are significantly higher than that of FF-SPC flour and extrudates. The OAC of FF-SPC flour is significantly higher than that of FFSF in both varieties, while that of the extrudates is significantly lower than that of their corresponding flours. EA and ES of extrudates of clark 63K and SCS1showed significantly higher values than the corresponding unprocessed flours. In general, the EA of SCS1 products are lower than that of Clark 63K, and the ES of Clark 63K and SCS1 is closer. The FC of FFSF is significantly higher than that of all products of both varieties. The FS of FFSF has been significantly higher than that of FF-SPC while the extrudates of SCS1 showed higher values of FS than that of Clark 63K. Generally, the present study showed that both varieties are suitable for extrusion cooking, with SCS1 slightly better performance. Based on the outcome of the study, the technology for developing an extruded product of soybean varieties has been suggested. Key words: Concentrate; extrusion cooking; flour; soybean

description: Understanding and probing phase transitions in non-equilibrium systems is an ongoing challenge in physics. A particular instance are phase transitions that occur between a non-fluctuating absorbing phase, e.g., an extinct population, and one in which the relevant order parameter, such as the population density, assumes a finite value. Here we report the observation of signatures of such a non-equilibrium phase transition in an open driven quantum system. In our experiment rubidium atoms in a quasi one-dimensional cold disordered gas are laser-excited to Rydberg states under so-called facilitation conditions. This conditional excitation process competes with spontaneous decay and leads to a crossover between a stationary state with no excitations and one with a finite number of excitations. We relate the underlying physics to that of an absorbing state phase transition in the presence of a field (i.e. off-resonant excitation processes) which slightly offsets the system from criticality. We observe a characteristic power-law scaling of the Rydberg excitation density as well as increased fluctuations close to the transition point. Furthermore, we argue that the observed transition relies on the presence of atomic motion which introduces annealed disorder into the system and enables the formation of long-ranged correlations. Our study paves the road for future investigations into the largely unexplored physics of non-equilibrium phase transitions in open many-body quantum systems.

It provides the opportunity to study transition form factors induced by these bulk-to-boundary propagators, both for on-shell and off-shell hadrons. This is a continuation of our study of hadron form factors induced by the bulk-to-boundary propagator with total angular momentum $J=1$ (e.g., electromagnetic form factors of mesons, nucleons, and nucleon resonances).

description: In this paper heavy quark energy loss models are embedded in full event-by-event viscous hydrodynamic simulations to investigate the nuclear suppression factor and azimuthal anisotropy of D$^0$ mesons in PbPb collisions at 5.02 TeV in the $p_T$ range 8-40 GeV. In our model calculations, the $R_\text{AA}$ of D$^0$ mesons is consistent with experimental data from the CMS experiment. We present the first calculations of heavy flavor cumulants $v_2\{2\}$ and $v_3\{2\}$ (and also discuss $v_2\{4\}$), which is also consistent with experimental data. Event-shape engineering techniques are used to compute the event-by-event correlation between the soft hadron $v_n$ and the heavy meson $v_n$. We predict a linear correlation between these observables on an event-by-event basis.

description: Several new physics scenarios that address anomalies in $B$-physics predict an enhancement of $b \rightarrow s ττ$ with respect to its Standard Model prediction. Such scenarios necessarily imply modifications of the lifetime ratio $τ_{B_{s}}/τ_{B_{d}}$ and the lifetime difference $ΔΓ_{s}$. In this work, we explore indirect bounds provided by these observables over new physics scenarios. We also estimate future projections, showing that future experimental and theoretical improvements on both $τ_{B_{s}}/τ_{B_{d}}$ and $ΔΓ_{s}$ have the potential to provide bounds competitive with those directly extracted from $b\rightarrow s ττ$ transitions. After performing a model-independent analysis, we apply our results to the particular case of leptoquark mediators proposed to address the $R_{D^{(*)}}$ anomalies.

Chronopolitanism: political inclusion and the distant future
Creators: name: John, Tyler M.
Publisher: name: No Publisher Supplied
Year: 2022

description: An area of recent philosophical interest concerns longtermism. Longtermism is the view that we should be particularly concerned with (even distant) future generations. It is sometimes strengthened in the form of strong longtermism, the view that the primary determinant of the moral value of our actions today is their effect on the long-term future. The long-term future, here, refers to a period of time surprisingly far into the future, such as 1,000 years from now. Progenitors of longtermism have characteristically been most concerned, morally, with the aggregate welfare of the long-term future, and practically, with work to reduce the risk of human extinction. I aim to broaden the scope of longtermist reflection, morally, by providing an analysis of a set of non-welfarist and non-consequentialist intergenerational ideals, and practically, by providing an analysis of a set of interventions which may rival extinction risk reduction in the value of their long-term effects. In Chapter 1, I consider the prospects for extending the non-welfarist and (predominantly) nonconsequentialist ideals of political legitimacy to future generations, contrary to the tacit assumptions of political philosophers. I show that, among extant accounts of political legitimacy, the most promising accounts of the grounds of political legitimacy imply that States have duties of legitimacy to future generations as well as to present citizens. In Chapter 2, I analyse a set of interventions for improving the value of the far future through the amelioration of political short-termism, the excessive priority that political systems give to present net benefits at the cost of future ones. I show that one popular set of proposed interventions centred on youth empowerment is unlikely to significantly increase the time horizons of political systems, and propose a novel set of political institutions employing a novel system of retrospective accountability which shows much greater promise. In Chapter 3, I analyse a set of interventions for improving the value of the far future through a form of moral values change, specifically interventions which seek to improve the far future by shaping humanity’s moral attitudes towards nonhuman animals today. This set of interventions is initially promising, but its case hinges on highly controversial theory about consciousness, the persistence of changes to human values, and about the psychological relationship between our various moral attitudes.

description: Light spectator fields may not be dynamically relevant for the inflationary phase of the early universe, but they can still induce interesting imprints on cosmological observables. In this paper, we compute the cross-correlations of the inflationary perturbations, both scalar and tensor, with the fluctuations of a non-minimally interacting spectator field using the in-in formalism and investigate the consistency relations associated with such cross-correlations. In particular, the scalar consistency relation is derived semi-classically by generalizing the consistency relation obtained earlier for cosmic magnetic fields. Notably, we find that the direct coupling between the inflaton and the spectator solely determines the local non-linearity parameter associated with the scalar cross-correlation during slow-roll inflation, regardless of the specific form of the Lagrangian for the spectator field. Further, we calculate the tensor correlation with spectator fluctuations, explore the associated soft limits, and demonstrate the violation of the conventional tensor consistency relation with a non-minimal derivative coupling. Our analysis stresses that the violation of tensor consistency relations does not necessarily imply the superhorizon evolution of tensor modes. Instead, such violations can arise due to the non-minimal derivative coupling of the spectator field to gravity. Finally, we discuss the wider implications of our results in the context of cosmological soft theorems.

Effects of Controlled Atmosphere Storage and Temperature on Quality Attributes of Mango
Creators: name: Hailu, Zinabu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study was conducted to analyze the effects of Controlled Atmosphere Storage (CAS) and low temperatures on quality attributes of cv. Keitt mango. Mango is one of the choicest fruits in the world and popular due to its delicious taste, pleasant aroma and nutritional value. To date, only 3% of the total world production is being exported due to the perishable nature of the product, lack of proper storage and other postharvest related diseases. Post-harvest loss of mango in Ethiopia is estimated to be between 25-40% and would occurred during handling, transportation and storage. Storage loss could exist through main factors affecting the quality of mangoes which are atmospheric conditions and temperatures. CAS is an agricultural technology which monitor and adjust constantly the level of CO2 and O2 within storage to reduce the rate of physiological and biochemical changes, ethylene sensitivity and incidence of decay development of mangoes and also inhibit pathogen growth. Up to now only very few number of research was done on the effects of CAS on Ethiopian mango. Thus, this study hopes to shed some light on the determination of optimum storage condition of Ethiopian mango and in effect to reduce the large postharvest loss of mango. The experimental design was designed by randomized block design for both factors; CAS and temperatures. The Controlled Atmosphere Storage (CAS) had four experimental treatments:-at constant storage temperature of 7oC and its atmospheric conditions A (10%CO2 + 6%O2), B (8%CO2+ 6%O2), C (5%CO2+5%O2) and Control (ambient condition). Storage temperature with 7, 10,13oC and control (ambient temperature) treatments also accomplished. The result showed the effect of CAS on weight loss and firmness of the cv. Keitt mango is significant between fruits stored in CAS and ambient atmosphere and LSD at 0.05=3.12 and 1.708 respectively. And the effect of temperature on TSS, TAA, pH, weight loss, firmness and skin color was significant effects between fruits stored within the designed treatments and their LSD values at 0.05 was( 0.317,6.58, 3.46, 4.148, 6.50 and 2.41).The effects of CAS and temperature on quality attributes of the stored fruits were confirmed by sensory analysis. Therefore, fruits stored at 7oC with 10%CO2 +6%O2 have best sensory preference to extend the storage life of cv. Keitt mangoes beyond 6weeks. In addition, fruits stored at 13oC without considering the effect of CA conditions also best and can store up to 21 days without Chilling Injuries (CI) effect. Finally, it can be conclude that CAS is important in extending storage life of cv. Keitt mango up to 6 weeks with the optimum atmospheric conditions (at 7oC and 10%CO2 + 6%O2) and it can also store at temperature of 13oC for 3 weeks without significant quality loss and CI effect

description: Generic sentence embeddings provide a coarse-grained approximation of semantic textual similarity but ignore specific aspects that make texts similar. Conversely, aspect-based sentence embeddings provide similarities between texts based on certain predefined aspects. Thus, similarity predictions of texts are more targeted to specific requirements and more easily explainable. In this paper, we present AspectCSE, an approach for aspect-based contrastive learning of sentence embeddings. Results indicate that AspectCSE achieves an average improvement of 3.97% on information retrieval tasks across multiple aspects compared to the previous best results. We also propose using Wikidata knowledge graph properties to train models of multi-aspect sentence embeddings in which multiple specific aspects are simultaneously considered during similarity predictions. We demonstrate that multi-aspect embeddings outperform single-aspect embeddings on aspect-specific information retrieval tasks. Finally, we examine the aspect-based sentence embedding space and demonstrate that embeddings of semantically similar aspect labels are often close, even without explicit similarity training between different aspect labels.

Nanostructured silane coatings for corrosion resistance of low carbon steel
Creators: name: Balan, Poovarasi
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The overall aim of this work is to design an alternative metal pre-treatment with improved corrosion resistance and low environmental impact. Hybrid silane pre-treatments with nano-additives and corrosion inhibitors as fillers for corrosion protection of low carbon steels using sol-gel processing technique were developed. Multifunctional silane molecules used to design the hybrid silane films were based on cross-condensation between an epoxy-silane, 3-glycidoxy-propyl-trimethoxy-silane (GPTMS) and methyl-triethoxy-silane (MTES) in acid catalysis condition. The silane films thus developed on low carbon steel surface also showed good adhesion, verified by Fourier Transform Infra-red Spectroscopy (FTIR). The corrosion resistance of the silane films modified with impregnation of corrosion inhibitors (i.e. rare earth salts) and/or silica nanoparticles was evaluated by electrochemical measurements using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The corrosion studies were complimented by investigation of surface topography and wetting properties using scanning electron microscopy coupled with energy dispersive x-ray spectroscopy (SEM-EDX) and contact angle measurements, respectively. This work aided the identification of the synergistic effects of both additives in efficient retardation of corrosion kinetics of the low carbon steel. The direct addition of active lanthanum triflate species, was found to have detrimental effects effect on corrosion resistance of the steel. The investigation also included cerium and yttrium triflates, for activation of silica nanoparticles within hybrid silane network for corrosion protection of low carbon steel. The electrochemical investigations elucidate the superior corrosion resistance of cerium activated systems on low carbon steel, as compared to lanthanum and yttrium triflates. It is proposed that the cerium triflates within the silane films on coated steels, forms cerium oxides or hydroxides on cathodic and anodic regions as a result of increase in pH during corrosion, thus hindering further progression of the corrosion onset. Optimum concentration of the cerium activated systems for the best corrosion resistance of low carbon steel was also established in this study.

Dynamical Time-Reversal Symmetry Breaking and Photo-Induced Chiral Spin Liquids in Frustrated Mott Insulators

description: The search for quantum spin liquids in frustrated quantum magnets recently has enjoyed a surge of interest, with various candidate materials under intense scrutiny. However, an experimental confirmation of a gapped topological spin liquid remains an open question. Here, we show that circularly-polarized light can provide a novel knob to drive frustrated Mott insulators into a chiral spin liquid (CSL), realizing an elusive quantum spin liquid with topological order. We find that the dynamics of a driven Kagome Mott insulator is well-captured by an effective Floquet spin model, with heating strongly suppressed, inducing a scalar spin chirality $S_i \cdot (S_j \times S_k)$ term which dynamically breaks time-reversal while preserving SU(2) spin symmetry. We fingerprint the transient phase diagram and find a stable photo-induced CSL near the equilibrium state. The results presented suggest employing dynamical symmetry breaking to engineer quantum spin liquids and access elusive phase transitions that are not readily accessible in equilibrium.

description: As an efficient approach to understand, generate, and process natural language texts, research in natural language processing (NLP) has exhibited a rapid spread and wide adoption in recent years. Given the increasing research work in this area, several NLP-related approaches have been surveyed in the research community. However, a comprehensive study that categorizes established topics, identifies trends, and outlines areas for future research remains absent. Contributing to closing this gap, we have systematically classified and analyzed research papers in the ACL Anthology. As a result, we present a structured overview of the research landscape, provide a taxonomy of fields of study in NLP, analyze recent developments in NLP, summarize our findings, and highlight directions for future work.

Fabrication, characterization and application of ultra-high concentration calcium alginate beads

description: Calcium alginate hydrogel beads have been widely studied as a carrier matrix for the delivery of food and pharmaceutical compounds due to its non-toxicity, renewability, and the ease of forming hydrogel beads with divalent cations. However, alginate hydrogel beads are known to have low stiffness, i.e., Young’s modulus < 1 MPa, and a short dissolution time of between 1 h to 2 h in the gastrointestinal fluid thus limiting some applications that require prolonged release of compounds. This study was aimed to fabricate calcium alginate beads with high stiffness and extended dissolution profile by increasing the alginate concentration beyond the critical viscosity limit (approximately 5,000 mPa.s) that can be processed using the existing extrusion-dripping system. A temperature-controlled extrusion-dripping method was developed and the feasibility of producing alginate beads at ultra-high concentration (UHC) with an initial viscosity up to 353,000 mPa.s was studied for the first time. The operating temperatures studied were ranged from 40°C to 80°C. Fourier-transform infrared spectroscopy (FTIR) analysis indicated that the chemical properties of the alginate gels were not affected by the operating temperature. The UHC beads have an extraordinary internal structure with thick calcium-alginate matrices and large pores in between the matrices. The dissolution time of the UHC calcium-alginate beads (i.e., 10% w/v) was 2.5 times longer than that of the normal beads (i.e., 2% w/v). The UHC beads had a Young’s modulus value up to 3.6 MPa, which was approximately 8 times higher than the normal beads. The Young’s modulus of the drug loaded UHC alginate beads was found to remain intact after 2.5 h in simulated intestinal fluid (SIF), whereas the normal beads (i.e., 2% w/v) were disintegrated after 30 min. The release of hydrophilic drugs (i.e., paracetamol and methylene blue) from UHC beads was approximately 2.5 times longer than the normal beads. The release kinetics of paracetamol fitted well with the first-order model (r² > 0.96) and followed the Fickian mechanism (n < 0.43). The release kinetics of methylene blue fitted well with the Korsmeyer-peppas model (r² > 0.98) and followed the non-Fickian mechanism (0.43 < n < 0.85). On the other hand, the release kinetics of the water-insoluble drug (i.e., ketoprofen) fitted well with the Korsmeyer-peppas model (r² > 0.98) and followed the Case-II transport mechanism (n > 0.85). It is worth noting that the ketoprofen release from UHC beads exhibited a time lag of 60 min. These findings show that the UHC calcium-alginate beads with high stiffness and extended dissolution profile can be prepared without the need for chemical modification, additional processing steps, or incorporation of additives. The UHC calcium-alginate beads open up the windows of opportunities for applications in sustained delivery of drugs and food ingredients.
