description: The Campi Flegrei volcanic field (Italy) poses very high risk to the highly urbanized Neapolitan area. Eruptive history was dominated by explosive activity producing pyroclastic currents (PDCs; (Proclastic Density Currents) ranging in scale from localized base surges to regional flows. Here we apply probabilistic numerical simulation approaches to produce PDC hazard maps, based on a comprehensive spectrum of flow properties and vent locations. These maps and provide all probable Volcanic Explosivity Index (VEI) scenarios from different source vents in the caldera, relevant for risk management planning. For each VEI scenario, we report the conditional probability for PDCs (i.e., the probability for a given area to be affected by the passage of PDCs) and related dynamic pressure. Model results indicate that PDCs from VEI<4 events would be confined within the Campi Flegrei caldera, PDC propagation being impeded by the northern and eastern caldera walls. Conversely, PDCs from VEI 4-5 events could invade a wide area beyond the northern caldera rim, as well as part of the Naples metropolitan area to the east. A major controlling factor of PDC dispersal is represented by the location of the vent area. PDCs from the potentially largest eruption scenarios (analogous to the ~15 ka, VEI 6 Neapolitan Yellow Tuff or even the ~39 ka, VEI 7 Campanian Ignimbrite extreme event) would affect a large part of the Campanian Plain to the north and the city of Naples to the east. Thus, in case of renewal of eruptive activity at Campi Flegrei, up to 3 million people will be potentially exposed to volcanic hazard, pointing out the urgency of an emergency plan. Considering the present level of uncertainty in forecasting the future eruption type, size and location we suggest that appropriate planning measures should face at least the VEI 5 reference scenario (at least 2 occurrences documented in the last 10 ka)

description: Applying and augmenting the theoretical framework of the Dutch disease, this paper investigates potential negative effects from the petroleum industry in Norway on agricultural profitability, and implicitly on food security due to the farmland abandonment effect. Two fundamental transmission channels of the oil price with an impact on agricultural profitability are analysed by vector equilibrium correction models: (1) The impact on producer prices, which affect input prices and then the costs of production; (2) The impact on food imports via the import-weighted exchange rate. A third channel is the wage differential in the respective sectors. Arguably, further consequences of low profitability and less farmland area are an increased pressure to become more efficient, which may result in increased use of antibiotics and increased depletion of soil. Therefore, due to the natural limits of boosting efficiency in biological systems and the farmland abandonment effect, Dutch disease in the agricultural sector is generally more serious than in the classical deindustrialisation case.

description: Here we report on the translocation of folded polymers through nano-pores using molecular dynamic simulations. Two cases are studied; one in which a folded molecule unfolds upon passage and one in which the folding remains intact as the molecule passes through the nano-pore. The topology of a folded polymer chain is defined as the arrangement of the intramolecular contacts, known as circuit topology. In the case where intramolecular contacts remain intact, we show that the dynamics of passage through a nano-pore varies for molecules with differing topologies: a phenomenon that can be exploited to enrich certain topologies in mixtures. We find that the nano-pore allows reading of topology for short chains. Moreover, when the passage is coupled with unfolding, the nano-pore enables discrimination between pure states, i.e., states for which the majority of contacts are arranged identically. In this case, as we show here, it is also possible to read the positions of the contact sites along a chain. Our results demonstrate the applicability of nano-pore technology to characterize and sort molecules based on their topology.

description: Context. Despite the thorough work of van Leeuwen (2007), the parallax of alpha Centauri is still far from being carved in stone. Any derivation of the individual masses is therefore uncertain, if not questionable. And yet, that does not prevent this system from being used for calibration purpose in several studies. Aims. Obtaining more accurate model-free parallax and individual masses of this system. Methods. With HARPS, the radial velocities are not only precise but also accurate. Ten years of HARPS data are enough to derive the complement of the visual orbit for a full 3D orbit of alpha Cen. Results. We locate alpha Cen (743 mas) right where Hipparcos (ESA 1997) had put it, i.e. slightly further away than derived by Soderhjelm (1999). The components are thus a bit more massive than previously thought (1.13 and 0.97 Msun for A and B respectively). These values are now in excellent agreement with the latest asteroseismologic results.

description: Atomically thin group-VIB transition metal dichalcogenides (TMDs) have recently emerged as a new class of two-dimensional (2D) semiconductors with extraordinary properties including the direct band gap in the visible frequency range, the pronounced spin-orbit coupling, the ultra-strong Coulomb interaction, and the rich physics associated with the valley degree of freedom. These 2D TMDs exhibit great potentials for device applications and have attracted vast interest for the exploration of new physics. 2D TMDs have complex electronic structures which underlie their physical properties. Here we review the bulk electronic structures in these new 2D materials as well as the theoretical models developed at different levels, along which we sort out the understandings on the origins of a variety of properties observed or predicted.

description: We explore the observational adequacy of a class of Unified Dark Energy/Matter (UDE/M) models with a fast transition. Our constraints are set using a combination of geometric probes, some low redshift ones, and some high redshift ones (CMB related included). The transition is phenomenologically modeled by two different transition functions corresponding to a fast and to an ultra-fast transition respectively. We find that the key parameters governing the transition can be well constrained, and from the statistical point of view it follows that the models cannot be discarded when compared to $Λ$CDM. We find the intriguing result that standard/input parameters such as $Ω_m$ and $Ω_b$ are far better constrained than in $Λ$CDM, and this is the case for the derived/output parameter measuring the deceleration value at present, $q_0$.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: BACKGROUND: IPLS is a term applied to the single system for reporting and distribution pharmaceutical items based on the overall mandate and scope of the PFSA. This system aims to provide patients pharmaceuticals they need. In order for this system to be successful, it must fulfil all the six rights of supply chain management which are ensuring right type of item, of the right quality, in the right quantity, at the right place, at the right time and with the right cost. At a facility level, IPLS incorporates all the three logistic functions which are Logistic Management Information System, Inventory Control System, and Storage System of pharmaceuticals. OBJECTIVES: To assess implementation of Integrated Pharmaceutical Logistics System in Black Lion Hospital METHODS AND MATERIALS: An explanatory descriptive approach was used in the study whereby the LMIS, the inventory control system and the storage system of the hospital was assessed and examined against the requirements and standards of IPLS. Purposive sampling technique was used to collect data. In addition, check lists, interview guides & observations were some of the tools used in the data collection process. RESULT: Detail results pertaining to major indicators of IPLS implementation such as availability & proper use of LMIS, LMIS data quality, training and supervision on logistics management, stock availability, availability of expired items, fulfillment of acceptable storage conditions for ARV drugs store room, resupply period, order fill rate, emergency order trends and major challenges on IPLS implementation are described and presented in the result section of this paper. CONCLUSION & RECOMMENDATION: With respect to some measurements such as availability of LMIS tools, supervision and training, availability of drugs, resupply period, emergency order trend, the effort towards IPLS implementation in the Hospital is encouraging. But much gap is observed in some other measurements such as in proper utilization of LMIS tools, LMIS data quality, and perceived order fill rate and storage conditions which leads to an overall conclusion that IPLS is not being implemented in the Hospital in full scale. In order to bring improvements, among other things, there should be regular supportive supervision and continuous trainings, in placing consistent monitoring and evaluation mechanisms, enforcing strict adherence to the IPLS SOP procedures and standards, and increased commitment of top management

description: Fog computing adds decentralized computing, storage, and networking capabilities with dedicated nodes as an intermediate layer between cloud data centers and edge devices to solve latency, bandwidth, and resilience issues. However, in-troducing a fog layer imposes new system design challenges. Fog systems not only exhibit a multitude of key system characteristics (e.g., security, resilience, interoperability) but are also beset with various interdependencies among their key characteristics that require developers' attention. Such interdependencies can either be trade-offs with improving the fog system on one characteristic impairing it on another, or synergies with improving the system on one characteristic also improving it on another. As system developers face a multifaceted and complex set of potential system design measures, it is challenging for them to oversee all potentially resulting interdependencies, mitigate trade-offs, and foster synergies. Until now, existing literature on fog system architecture has only analyzed such interdependencies in isolation for specific characteristics, thereby limiting the applicability and generalizability of their proposed system designs if other than the considered characteristics are critical. We aim to fill this gap by conducting a literature review to (1) synthesize the most relevant characteristics of fog systems and design measures to achieve them, and (2) derive interdependences among all key characteristics. From reviewing 147 articles on fog system architectures, we reveal 11 key characteristics and 39 interdependencies. We supplement the key characteristics with a description, reason for their relevance, and related design measures derived from literature to deepen the understanding of a fog system's potential and clarify semantic ambiguities. For the interdependencies, we explain and differentiate each one as positive (synergies) or negative (trade-offs), guiding practitioners and researchers in future design choices to avoid pitfalls and unleash the full potential of fog computing.

description: Over the last years, the concept of energy communities has gained popularity. They are increasingly perceived as a citizen empowerment opportunity, and a mean to involve them in renewable energy deployment. Yet, deployment of energy communities remains limited. Among the explanatory factors of this observation, one can cite the lack of appropriate legislation, but also the lack of knowledge (of citizen but also professionals) around new forms of business models, with an ensured added value for all stakeholders. The research results presented here have been obtained through the work conducted in R2EC (Regional Renewable Energy Cells) ERANet project, which intends to evaluate revenue model(s) for an energy community (EC) created in a neighborhood of the municipality of Flobecq (Wallonia, Belgium). The objective is also to evaluate to which extent this model could be replicated in similar settings, elsewhere in Wallonia. Results show that the local regulation defining renewable energy communities should be adapted, as it is currently too restrictive and prevents sufficient economic value creation to make shared energy generation concepts viable. Peer-topeer exchange, currently excluded from regulatory frameworks, was identified by our research as a non-optimal business model given the current context in Wallonia (i.e., net-metering).

description: Exciton, trion and electron spin dynamics in a 20 nm wide modulation-doped GaAs single quantum well are investigated using resonant ultrafast two-color Kerr rotation spectroscopy. Excitons and trions are selectively detected by resonant probe pulses while their relative spectral weight is controlled by adjusting the gate voltage which tunes the carrier density. Tuning the carrier density markedly influences the spin decay time of the two dimensional electron gas. The spin decay time can be enhanced by a factor of 3 at an intermediate carrier concentration in the quantum well, where excitons and trions coexist in the system. In addition, we explore the capability to tune the g-factor of the electron gas via the carrier density.

Studying Social Tendencies: Is the Will of the Majority Being Replaced by the Tyranny of the Minority in the United States?

description: Constitutions are not carved in stone for a reason. They reflect the times when they were drafted; the political, social, economic, and ethical panorama in existence when they were written. However, these factors change over time, often at an increasingly faster pace. One could argue that the last decade in the U.S. reflects a period of political upheaval unparalleled in the nation’s history. One crucial consequence of this is the growth in anti-democratic tendencies that some feel has already ushered in minority rule, whereby the political landscape and the country’s laws no longer are in tune with the wishes of the majority. The Electoral College is the most evident “culprit” here, although it is not alone: systematic gerrymandering and voter suppression, and a Supreme Court and federal court system that for the most part reflect ultra-conservative principles, along with a strict, “originalist” interpretation of the Constitution, are conspiring to exploit the anti-democratic potential of the electoral system in the U.S. This article will consider these features in more detail.

description: In a context of differentiation of agricultural worlds, we propose an analysis of the ongoing transformations and social conditions of these recompositions. We approached these questions from the point of view of land issues, based on observations made around a city in the west of France, Angers. Farmers, in their relationship to the land and to the locality, demonstrate four land strategies: “professional anchoring,” “flexibility,” “patrimonialization”, and “hedonism.” These strategies organize a question of land use which is unstable and results in competition and adjustment processes for access to land, both on the part of farmers and institutional procedures. These recompositions operate through different moments of debate, ranging from peer discussions, to local meetings with elected officials or inhabitants, to established negotiations between local authorities. Farmers have to deal with actors from outside their professional world, and paradoxically, rather than entering into a logic of withdrawal, we see a recomposition combining professional excellence and territorial anchoring.

Measurement of hadron suppression and study of its connection with vanishing $v_{\mathrm{3}}$ at low $\sqrt{s_{\mathrm{NN}}}$ in Au+Au collisions with STAR

description: At top RHIC and LHC energies the suppression of high transverse momentum ($p_{\mathrm{T}}$) hadrons provides evidence for partonic energy loss in QGP. We study partonic energy loss in the RHIC Beam Energy Scan (BES) by investigating the centrality dependence of the binary-collision-scaled high-$p_{\mathrm{T}}$ yields. Observing a decrease of the scaled yield in more central collisions is proposed as a possible signature for jet quenching. Even at energies and centralities where this signature is lost a QGP may still be formed since competing phenomena responsible for enhancements may overwhelm the suppression from energy loss. Measurements in several ranges of $p_{\mathrm{T}}$ from $\sqrt{s_{_{\mathrm{NN}}}}$ = 7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV data show that relative hadron suppression persists at least down to 14.5 GeV. To further investigate both the possible formation of a QGP at these lower energies and whether the observed hadron suppression coincides with the onset of other QGP signatures, we examine the energy and centrality dependence of $v_{3}$. Models have shown that the development of $v_{3}$ requires the presence of a low viscosity phase early in the collision. We find that for collisions with $N_{\mathrm{part}}$<50, $v_{3}$ disappears for energies below 14.5 GeV, suggestive of a turn-off of the QGP. But for $N_{\mathrm{part}}$>50, $v_{3}$ persists down to the lowest energies. Together, these signatures provide possible evidence for the formation of a QGP in the lowest energy collisions at RHIC.
Cryogenic fuelling of engines and fundamental droplet evaporation behaviour

Publisher: name: Loughborough University
Year: 2021
Subjects: Mechanical engineering not elsewhere classified

description: Liquefied natural gas (LNG), from fossil and renewable sources, is currently in use as an alternative transportation fuel with significant environmental and economic advantages compared to petroleum fuels. However, current LNG vehicles waste the potential thermomechanical exergy of the fuel (~1 MJ kg^-1) by vaporising the fuel before delivery to the engine. The proposed solution is to deliver the fuel to the engine in the liquid phase and harness the evaporative charge cooling to increase engine performance. This research provides a robust thermodynamic foundation for this LNG engine concept and resolves significant knowledge gaps in droplet evaporation theory that allows the validity of classical droplet evaporation models to be assessed. Results from a dedicated thermodynamic model for spark-ignited homogeneous-charge engines, constructed as part of this research, show significantly decreased fuel consumption (-8.9%), increased brake mean effective pressure (+18.5%) and reduced NOx emissions (-51%) when liquid phase LNG is directly injected into the cylinder at near bottom-dead-centre with the intake valve closed, compared to the conventional port-injected gaseous fuel. The mechanisms for this change are a combination of decreased mixture temperatures, reduced heat losses, increased trapped mass, increased compression ratio and advanced spark timing. In some high-load instances, the additional mechanical work obtained can exceed the thermomechanical exergy of the fuel. Understanding of droplet evaporation phenomena is crucial if a true LNG engine is to be optimised. However, current droplet evaporation models are based on a range of assumptions that can not generally be taken for granted. A new, fundamental, fully transient droplet evaporation model that accounts for the moving droplet surface has been created and implemented to show that significant deviations from the classical d^2-law can arise due to transient effects in the gas phase. As significant outputs of this research, a new method for evaluating appropriate ?film properties is proposed that significantly reduces errors compared to the 1/3 rule and a tool is proposed that quantifies errors from the widely-applied quasi-steady assumption. The methods are generic to all droplet evaporation problems so have utility far beyond the present target application. For liquid methane droplets at engine intake conditions, evaporation rate errors are reduced from 8.5% to 0.3% for the new transport property method compared to the 1/3 rule and it is shown that errors from the quasi-steady assumption are 1-4%.

description: This research aims to examine factors affecting public procurement performance in Ethiopia: the case of Public Procurement and Property Disposal Services. Based on literature reviews, the researcher identified four factors that affect the procurement performance. These includes: procurement planning, unethical practices, competency of staff, procurement procedure and Information Communication Technology on procurement. The hypothesis of the study was the procurement factors (independent variables) affect the procurement performance (dependent variable) of PPPDS. The research design is made based on descriptive and explanatory research approaches. The researcher distributed 116 questionnaires and 97 were filled and returned. Both primary and secondary data were used throughout this research. For primary data, both structured and semi structured type questionnaires were prepared. The results of this study indicate that the independent variables (Procurement Planning, Competency of Staff, Procurement Procedure and Information Communication Technology) positively affect the dependent variable (procurement performance) to a significant extent. These factors explain 85.9% of procurement performance, while the rest 14.1% is explained by other factors which are not subject of this study. Key words: Procurement Planning, Competency of Staff, Procurement Procedures, Utilization of Information Communication Technology

description: We investigated the giant resonance in Xenon by high-order harmonic generation spectroscopy driven by a two-color field. The addition of a non-perturbative second harmonic component parallel to the driving field breaks the symmetry between neighboring sub-cycles resulting in the appearance of spectral caustics at two distinct cut-off energies. By controlling the phase delay between the two color components it is possible to tailor the harmonic emission in order to amplify and isolate the spectral feature of interest. In this paper we demonstrate how this control scheme can be used to investigate the role of electron correlations that give birth to the giant resonance in Xenon. The collective excitations of the giant dipole resonance in Xenon combined with the spectral manipulation associated with the two color driving field allow to see features that are normally not accessible and to obtain a quantitative good agreement between the experimental results and the theoretical predictions.

description: The TRACER project supports a number of coal-intensive regions around Europe to design (or re-design) their Research and Innovation (R&I) strategies in order to facilitate their transition towards a sustainable energy system. The TRACER consortium consists of different target regions: South East Bulgaria, North West Bohemia - Czech Republic, Lusatian Lignite District - Germany, Western Macedonia - Greece, Upper Silesian Coalfield - Poland, West Region, Jiu Valley - Romania, Wales - UK, Kolubara - Serbia, Donetsk - Ukraine. Core activities of TRACER include the implementation of an EDP (Entrepreneurial Discovery Process) to mobilise a wide range of stakeholders in each target region to develop an appropriate governance structure and to bring regional stakeholders together to discuss and agree on a shared vision and priorities for coal transition. R&I strategies, industrial roadmaps and decision support tools will be developed jointly with key stakeholders of the TRACER target regions. Further TRACER activities include the identification and analysis of best practice examples of successful and ambitious transition processes in coal intensive regions, a detailed assessment of social, environmental and technological challenges, the elaboration of guidelines on how to mobilise investment as well as dedicated activities to stimulate R&I cooperation among coal intensive regions in Europe and beyond.

description: Adaptive techniques have important potential for wide applications in enhancing precision of quantum parameter estimation. We present a recursively adaptive quantum state tomography (RAQST) protocol for finite dimensional quantum systems and experimentally implement the adaptive tomography protocol on two-qubit systems. In this RAQST protocol, an adaptive measurement strategy and a recursive linear regression estimation algorithm are performed. Numerical results show that our RAQST protocol can outperform the tomography protocols using mutually unbiased bases (MUB) and the two-stage MUB adaptive strategy even with the simplest product measurements. When nonlocal measurements are available, our RAQST can beat the Gill-Massar bound for a wide range of quantum states with a modest number of copies. We use only the simplest product measurements to implement two-qubit tomography experiments. In the experiments, we use error-compensation techniques to tackle systematic error due to misalignments and imperfection of wave plates, and achieve about 100-fold reduction of the systematic error. The experimental results demonstrate that the improvement of RAQST over nonadaptive tomography is significant for states with a high level of purity. Our results also show that this recursively adaptive tomography method is particularly effective for the reconstruction of maximally entangled states, which are important resources in quantum information.

Acoustic Startle Events in Trailers for US Horror Films
Creators: name: Redfern, Nick
Publisher: name: Brill Online
Year: 2023
Subjects: Sensory processes, perception and performance

description: This article analyses the function and form of acoustic startle events (ASEs) in trailers for fifty US horror films released between 2011 and 2015. There are 173 ASEs in the sample, ranging from one startle up to a maximum of ten, with a median of three events per trailer. ASEs exhibit different types of relationships between figure and ground, with some events preceded by silence and anticipated by the viewer while others are unanticipated and intrude on scenes relying on a prior emotional state of apprehension. The functions of ASEs within the hybrid form of a trailer are emotional, narrational, aesthetic and attentional. Sound designers deploy ASEs to exploit the defensive mechanism of the startle response by using ASEs as a form of attentional redirect in order to engage the viewer with on-screen information and presenting marketing information to be remembered by the viewer during a hypervigilance phase. Startle events in the sample are typically the product of the interrelationship between sound design, editing, and movement, but there are also numerous instances when a startle event is not associated with a cut and a moment of horror is the product of the combination of an acoustic startle and movement only.

description: Increased energy efficiency and/or optimised energy management and/or integrate a higher share of renewables. Thus, the term energy communities in SHAREs refers to all forms of collective actions by and for consumers such as cooperatives, collective purchase groups or other consumer-driven collective actions. Six countries are involved in the project implementation: Austria, Germany, Croatia, Bulgaria, Georgia and Hungary. In order to achieve a clean energy transition, all consumer groups need to be involved and convinced to contribute to the energy market. Founders of energy communities are by definition very motivated and “on-board” but often lack the tools to engage with other consumer groups. The concept of the SHAREs project is simple and straightforward - to create a Gateway for those interested in setting up collective actions to help them initiate an action and grow. The Gateway will consist of: (1) A country-specific implementation toolkit to equip local heroes with the technical and logistic capacity to set up their energy community (legal framework, such as master contracts, technical and IT solutions, business models, etc.); (2) The building blocks of a tailored “pick-and-mix” communication campaign to enable local heroes to promote their idea effectively to their most relevant stakeholder groups. The Gateway will combine the insights and tools from existing initiatives as well as input of established energy communities (pioneers) and policy developers. After having been put to test and refined in at least 20 aspiring energy communities in 6 European countries, the Gateway will be broadly disseminated to relevant stakeholders all over Europe.

description: Photovoltaic (PV) energy plays an important role in the energy transition, especially for off-grid contexts, through a format of Hybrid Energy System (HES) with storage system. Yet, using a storage system comes with additional investment costs, extra environmental impact and maintenance issues, etc. For an off-grid PV/Diesel HES, a precisely designed Power Management System (PMS) with short-term solar forecast could be used to reduce or even avoid the use of energy storage system. Hence, this work aims to find out the feasibility of this concept, and introduce a new approach to evaluate the HES performance rather than using classic statistical metrics like Root Mean Square Error (RMSE) and MAE (Mean Absolute Error). Besides, several scenarios are tested to explore the influence of different elements on HES performance.

description: Results of experimental investigations of a neutron resonances width in planar waveguides using the time-of-flight reflectometer REMUR of the IBR-2 pulsed reactor are reported and comparison with theoretical calculations is presented. The intensity of the neutron microbeam emitted from the waveguide edge was registered as a function of the neutron wavelength and the incident beam angular divergence. The possible applications of this method for the investigations of layered nanostructures are discussed.

description: The pandemic, combined with additional conjunctural events, led to logistics prices hike as well as increases of raw materials prices. As many other industries, the solar PV sector was impacted, with substantial inflation of PV module prices, which approached the 0,30 US$/Wp. But such turmoil across the supply chain can also create opportunities, e.g. by enabling the competitiveness of local manufacturing in comparison with centralized, large scale manufacturing bases located in Asia. To assess these opportunities, this paper provides estimations of the factory gate cost of manufacturing PV modules using mono c-Si p-type PERC cells, in 2022 and 2025, through vertically integrated factories located in France, Morocco and South Africa of 1GW of production capacity. Results show that it remains challenging to be cost competitive with China-based vertically integrated manufacturing. The gap remains higher than 20%, even in the best-case situation, with 0,37 US$/Wp in France, 0,36 US$/Wp in South Africa and 0,34 US$/Wp in Morocco achievable in 2022. The most influential factors are economies of scale, polysilicon price, cell efficiency or the cost of electricity. Competitiveness can be reached in the medium-term, only by focusing on these factors simultaneously, and with the support of public authorities, direct and indirect.
