description: Potato is a valuable source for phytochemicals like vitamins, minerals, plant phenols, amino acids and proteins. However, environmental stress may affect the level of all these components. In this study, two purple breeding clones and one yellow fleshed cultivar (cv.) were assessed in their response to drought and wounding stress in two consecutive years. The plants were grown in the greenhouse under control (sufficient water supply) and with drought stress conditions. After harvest the tubers were analyzed for the content of soluble phenols and proteins in fresh tissue and after wounding. In addition, free amino acids (AAS) and activity of lipid acyl hydrolases (LAH) were assayed in control and drought stressed tubers. The results revealed significant differences in soluble phenols and proteins between genotypes, and that drought stress significantly increased the level of soluble proteins (P < 0.0001) and LAH activity (P < 0.001), but had no significant effect on the concentration of phenols. Moreover, total amounts of free AAS were higher in the drought stress variant. Wounding stress caused a significant increase of soluble phenols in cv. Agave. But, this was less prominent in purple clones which in general had higher contents of phenols. Proteins were also enhanced as a result of wounding, although, the effect of wounding stress on their level was smaller than that of drought stress.

description: We report on a quantum-classical simulation of the single-band Hubbard model using two-site dynamical mean-field theory (DMFT). Our approach uses IBM's superconducting qubit chip to compute the zero-temperature impurity Green's function in the time domain and a classical computer to fit the measured Green's functions and extract their frequency domain parameters. We find that the quantum circuit synthesis (Trotter) and hardware errors lead to incorrect frequency estimates, and subsequently to an inaccurate quasiparticle weight when calculated from the frequency derivative of the self-energy. These errors produce incorrect hybridization parameters that prevent the DMFT algorithm from converging to the correct self-consistent solution. To avoid this pitfall, we compute the quasiparticle weight by integrating the quasiparticle peaks in the spectral function. This method is much less sensitive to Trotter errors and allows the algorithm to converge to self-consistency for a half-filled Mott insulating system after applying quantum error mitigation techniques to the quantum simulation data.

description: After nerve injury, myelin and Remak Schwann cells reprogram to repair cells specialized for regeneration. Normally providing strong regenerative support, these cells fail in aging animals, and during chronic denervation that results from slow axon growth. This impairs axonal regeneration and causes significant clinical problems. In mice, we find that repair cells express reduced c-Jun protein as regenerative support provided by these cells declines during aging and chronic denervation. In both cases, genetically restoring Schwann cell c-Jun levels restores regeneration to control levels. We identify potential gene candidates mediating this effect and implicate Shh in the control of Schwann cell c-Jun levels. This establishes that a common mechanism, reduced c-Jun in Schwann cells, regulates success and failure of nerve repair both during aging and chronic denervation. This provides a molecular framework for addressing important clinical problems, suggesting molecular pathways that can be targeted to promote repair in the PNS.

description: A robust literature documents the health benefits of affectionate communication. The present study offers a meta-analysis of this literature to estimate general effects of affectionate communication on several areas of health, including cardiovascular, stress hormonal, stress reactivity, and mental health. We also examined potential moderators, including the type of affectionate communication and sex, while predicting that the benefits of expressed affection outweigh the benefits of received affection. We found a weighted mean effect of r = .23 for the relationship between affectionate communication and health, with differences based on type of health outcome but none for type of affection or sex. The effect of expressed affection exceeded the effect of received affection. The paper discusses the implications of these results.

description: We report on a study of vortex pinning in nanoscale antidot defect arrays in the context of the London Theory. Using a wire network model, we discretize the array with a fine mesh, thereby providing a detailed treatment of pinning phenomena. The use of a fine grid has enabled us to examine both circular and elongated defects, patterned in the form of a rhombus. The latter display pinning characteristics superior to circular defects constructed with the similar area. We calculate pinning potentials for defects containing zero and single quanta, and we obtain a pinning phase diagram for the second matching field, $H = 2 Φ_{o}$.

description: Using Giddens's structuration theory, this study examines how the routinized use of traditional and new media platforms differently align with the structures of everyday life. We analyzed data from a quantitative diary study in Germany to find that new media platforms specifically affect societal structuration by blurring the lines between obligations and leisure time. The part played by routines in the use of new media platforms was less strongly connected to clock time compared to traditional media platforms. Consequently, the findings indicate both a vanishing potential for media platform use as a social zeitgeber and the relevance of rules as structuring elements.

description: The present study attempted to highlight the concerns of shallow groundwater table depth (GWTD) to the sustainability of Wonji-Shoa Sugar Estate (WSSE), Upper Awash Valley of Ethiopia. The recent magnitude and fluctuation of GWTD is mapped in ArcView GIS (using universal kriging technique) from the monthly GWTD monitoring data (2007-2009) using piezometer tubes. The study result clearly showed that the GWTD at WSSE was extremely shallow, showed great spatio-seasonal variability and rising trend; thus, threatening the sustainability of WSSE significantly. About 90% of the plantation fields have GWTD above the critical depth of 1.5 m below the soil surface and, hence, critically waterlogged. As a result, the estate is recently achieving only 55% of the production potential realized in the 1960s. Past trends indicate that the GW has the potential to inundate Wonji plain and is anticipated to devastate production during the next 10-15 years. Therefore, in order to sustain production system in the region, there is an urgent need to identify the possible causes of waterlogging and investigate the feasible remedial measures to combat its problems. The spatial mapping of GWTD with identified problematic areas, indicated in the current study, is believed to provide a tool for water management and, hence, crucial for the decision making and actions taking processes.
Temperature Dependence of the Axion Mass in a Scenario Where the Restoration of Chiral Symmetry Drives the Restoration of the $U_A(1)$ Symmetry

description: The temperature ($T$) dependence of the axion mass is predicted for $T$'s up to $\sim 2.3 \times$ the chiral restoration temperature of QCD. The axion is related to the $U_A(1)$ anomaly. The squared axion mass $m_a(T)^2$ is, modulo the presently undetermined scale of spontaneous breaking of Peccei-Quinn symmetry $f_a$ (squared), equal to QCD topological susceptibility $χ(T)$ for all $T$. We obtain $χ(T)$ by using quark condensates calculated in two effective Dyson-Schwinger models of nonperturbative QCD. They exhibit the correct chiral behavior, including the dynamical breaking of chiral symmetry and its restoration at high $T$. This is reflected in the $U_A(1)$ symmetry breaking and restoration through $χ(T)$. In our previous studies, such $χ(T)$ yields the $T$-dependence of the $U_A(1)$-anomaly-influenced masses of $η'$ and $η$ mesons consistent with experiment. This in turn supports our prediction for the $T$-dependence of the axion mass. Another support is a rather good agreement with the pertinent lattice results. This agreement is not spoiled by our varying $u$ and $d$ quark mass parameters out of the isospin limit.

description: Conservation agriculture has been promoted in Zambia as a strategy to mitigate some of the negative effects arising from conventional tillage practices. Conservation agriculture offers several potential benefits on soil properties. However, these benefits and impacts vary across agro ecological regions and management practices. This study investigated changes, over time, associated with the practice of conservation agriculture in selected soil chemical, physical and biological properties, including an assessment of the effects on soil respiration, nodulation and biological nitrogen fixation in soya beans (Glycine max (L.) Merr). Six paired soil samples were collected from conservation agriculture and conventional tillage fields. Fields under conservation agriculture were 4, 7 and 16 years old while those under conventional tillage had been cultivated for over 18 years. Changes in soil properties due to conservation agriculture practice were determined using published laboratory procedures and compared using the paired t-test at 95% confidence level. The results indicated significantly higher soil pH, soil organic carbon, nodulation and biological nitrogen fixation under conservation agriculture than conventional tillage after seven years of practice. The study also showed significantly higher total porosity, soil microbial biomass, soil respiration and lower soil bulk density after sixteen years of practice. Based on these results, the practice of conservation agriculture has potential to improve crop productivity by improving the different aspects of soil fertility, the length of time before this is realized notwithstanding. Further studies that compare several conservation agriculture systems are recommended in other agro-ecological zones of the country to validate these findings.

description: The critical field of the Freedericksz transition and switching dynamics are investigated for polymer stabilized nematic liquid crystals as a function of polymer concentration. A simple phenomenological model is proposed to describe the observed critical field and dynamic response time behaviors as a function of concentration. In this model the polymer fibrils form director domains, which are bounded by virtual surfaces with a finite anchoring energy. The Freedericksz transition occurs independently within each of these domains.

description: Mastering robotic manipulation skills through reinforcement learning (RL) typically requires the design of shaped reward functions. Recent developments in this area have demonstrated that using sparse rewards, i.e. rewarding the agent only when the task has been successfully completed, can lead to better policies. However, state-action space exploration is more difficult in this case. Recent RL approaches to learning with sparse rewards have leveraged high-quality human demonstrations for the task, but these can be costly, time consuming or even impossible to obtain. In this paper, we propose a novel and effective approach that does not require human demonstrations. We observe that every robotic manipulation task could be seen as involving a locomotion task from the perspective of the object being manipulated, i.e. the object could learn how to reach a target state on its own. In order to exploit this idea, we introduce a framework whereby an object locomotion policy is initially obtained using a realistic physics simulator. This policy is then used to generate auxiliary rewards, called simulated locomotion demonstration rewards (SLDRs), which enable us to learn the robot manipulation policy. The proposed approach has been evaluated on 13 tasks of increasing complexity, and can achieve higher success rate and faster learning rates compared to alternative algorithms. SLDRs are especially beneficial for tasks like multi-object stacking and non-rigid object manipulation.

description: Using a recent homogeneous sample of 40 high quality velocity dispersion profiles for Galactic globular clusters, we study the low gravitational acceleration regime relevant to the outskirts of these systems. We find that a simple empirical profile having a central Gaussian component and a constant large radius asymptote, $σ_{\infty}$, accurately describes the variety of observed velocity dispersion profiles. We use published population synthesis models, carefully tailored to each individual cluster, to estimate mass to light ratios from which total stellar masses, $M$, are inferred. We obtain a clear scaling, reminiscent of the galactic Tully-Fisher relation of $σ_{\infty}( km s^{-1})= 0.084^{+0.075}_{-0.040} (M/M_{\odot})^{0.3 \pm 0.051} $, which is interesting to compare to the deep MOND limit of $σ_{\infty} (km s^{-1})=0.2(M/M_{\odot})^{0.25}$. Under a Newtonian interpretation, our results constitute a further restriction on models where initial conditions are crafted to yield the outer flattening observed today. Within a modified gravity scheme, as the globular clusters studied are not isolated objects in the deep MOND regime, the results obtained point towards a modified gravity where the external field effect of MOND does not appear, or is much suppressed.

description: Phasonic degrees of freedom are unique to quasiperiodic structures, and play a central role in poorly-understood properties of quasicrystals from excitation spectra to wavefunction statistics to electronic transport. However, phasons are challenging to access dynamically in the solid state due to their complex long-range character and the effects of disorder and strain. We report phasonic spectroscopy of a quantum gas in a one-dimensional quasicrystalline optical lattice. We observe that strong phasonic driving produces a nonperturbative high-harmonic plateau strikingly different from the effects of standard dipolar driving. Tuning the potential from crystalline to quasicrystalline, we identify spectroscopic signatures of quasiperiodicity and interactions and map the emergence of a multifractal energy spectrum, opening a path to direct imaging of the Hofstadter butterfly.

description: The state of the matter that is obscuring a small circumnuclear region in AGN can be probed by observations of its broad emission lines. Infrared lines are particularly useful since they penetrate significant columns of obscuring matter, the properties of which can be constrained by comparing infrared and X-ray obscuration. We report on new 4um spectroscopy of a sample of 12 Seyfert 2 galaxies, probing for broad components to the Brackett alpha 4.05um line. Broad components are observed in 3 to 4 objects. All objects with a broad component exhibit relatively low X-ray obscuring columns, and our results are consistent with a Galactic ratio of 4um obscuration to the BLR and X-ray column. In combination with observations of a NON-Galactic ratio of VISUAL obscuration of BLRs and X-ray obscuring column in Seyferts, and interpreted in a unified AGN scheme, this result can be reconciled with two interpretations. Either the properties of dust near the AGN are modified towards larger grains, for example through coagulation, in a way that significantly flattens the optical/IR extinction curve, or the ratio of dust obscuration to X-ray column varies for different viewing angles with respect to the axis of symmetry of the putative torus. Our spectra also provide a survey of emission in the [SiIX] 3.94um coronal line, finding variation by an order of magnitude in its ratio to Br alpha. The first extragalactic detection of the [CaVII] 4.09um and [CaV] 4.16um coronal lines is reported in the spectrum of the Circinus galaxy.

description: Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time - as often quantified from the comparison of their predicted stellar mass functions to observed stellar mass functions from data. In this paper we compare the clustering of galaxies from the hydrodynamical cosmological simulated lightcone Horizon-AGN, to clustering measurements from the VIDEO survey observations. Using mocks built from a VIDEO-like photometry, we first explore the bias introduced into clustering measurements by using stellar masses and redshifts derived from SED-fitting, rather than the intrinsic values. The propagation of redshift and mass statistical and systematic uncertainties in the clustering measurements causes us to underestimate the clustering amplitude. We find then that clustering and halo occupation distribution (HOD) modelling results are qualitatively similar in Horizon-AGN and VIDEO. However at low stellar masses Horizon-AGN underestimates the observed clustering by up to a factor of ~3, reflecting the known excess stellar mass to halo mass ratio for Horizon-AGN low mass haloes, already discussed in previous works. This reinforces the need for stronger regulation of star formation in low mass haloes in the simulation. Finally, the comparison of the stellar mass to halo mass ratio in the simulated catalogue, inferred from angular clustering, to that directly measured from the simulation, validates HOD modelling of clustering as a probe of the galaxy-halo connection.

description: FeCr2S4 is a ferrimagnet with two oppositely ordered spin sublattices (Fe and Cr), connected via superexchange interaction, giving a non-zero net magnetic moment. 
We show, using time-resolved measurements of the magneto-optic Kerr effect, how the magnetic dynamics of the sublattices can be selectively manipulated by resonantly perturbing the Fe sublattice with ultrashort laser pulses. The mid-infrared excitation through intra-atomic Fe d-d transitions triggers markedly slower dynamics in comparison to an off-resonant pumping affecting both of the two sublattices simultaneously. By changing probe wavelength to move in and out of resonance with the Fe d-d transitions, we also show the specific contributions of the Fe sublattice to these dynamics.

description: The literature has advocated the use of a clear and unambiguous label to inform adolescents of advertisements on social media. In this study, we introduce a norm-based label and determine its effects. In a series of three studies, we test a label that triggers the bandwagon heuristic (i.e., “your friends know this is sponsored”) and compare its effectiveness to a traditional label (i.e., “sponsored”) in a social network. The results reveal the normative label as more effective in activating adolescents' persuasion knowledge (Studies 1 and 2) and in triggering adolescents to select stricter ad settings (Study 3). In all studies, descriptive norms operate as the mediator. Based on these results, we discuss existing theories in light of social media.

description: Studies have confirmed the benefits of using Third-party logistics (TPL) for efficient construction management, especially in large projects. Nevertheless, there is a dearth of decision-making models evaluating the exact role of TPL providers as drivers for supply chain (SC) integration and optimisation. This study aims to develop a decision-making model for construction supply chain (CSC) optimisation, with possible TPL integration. The proposed model considers two types of purchased materials (type-1 and type-2) and assists the main contractor in determining construction supply chain management (CSCM) strategies, including supplier selection, order quantity determination, and TPL use evaluation. Using the model, the main contractor can take advantage of the TPL provider’s warehouse and order larger quantities, if necessary, to obtain lower prices offered by suppliers. Through case examples in Canada, we find that the proposed model performs better in optimising total SC cost, as compared to the model without TPL. Model validations also show that TPL can be conditionally used to improve construction logistics performance and to meet practical requirements targeting issues in the construction industry.

description: We have used two methods to search for surviving companions of Type Ia supernova progenitors in three Balmer-dominated supernova remnants (SNRs) in the Large Magellanic Cloud: 0519-69.0, 0505-67.9 (DEM L71), and 0548-70.4. In the first method, we use the Hubble Space Telescope photometric measurements of stars to construct color-magnitude diagrams (CMDs), and compare positions of stars in the CMDs with those expected from theoretical post-impact evolution of surviving main sequence or helium star companions. No obvious candidates of surviving companion are identified in this photometric search. Future models for surviving red giant companions or with different explosion mechanisms are needed for thorough comparisons with these observations in order to make more definitive conclusions. In the second method, we use Multi-Unit Spectroscopic Explorer (MUSE) observations of 0519-69.0 and DEM L71 to carry out spectroscopic analyses of stars in order to use large peculiar radial velocities as diagnostics of surviving companions. We find a star in 0519-69.0 and a star in DEM L71 moving at radial velocities of 182 $\pm$ 0 km s$^{-1}$ and 213 $\pm$ 0 km s$^{-1}$, more than 2.5$σ$ from the mean radial velocity of the underlying stellar population, 264 km s$^{-1}$ and 270 km s$^{-1}$, respectively. These stars need higher-quality spectra to investigate their abundances and rotation velocities to determine whether they are indeed surviving companions of the SN progenitors.

description: We analyze the dissipative quantum tunneling in the Caldeira-Leggett model by the nonperturbative renormalization-group method. We classify the dissipation effects by introducing the notion of effective cutoffs. We calculate the localization susceptibility to evaluate the critical dissipation for the quantum-classical transition. Our results are consistent with previous semiclassical arguments, but give considerably larger critical dissipation.

description: We describe an experiment to measure the polarization of the Cosmic Microwave Background (CMB) with the Degree Angular Scale Interferometer (DASI), a compact microwave interferometer optimized to detect CMB anisotropy at multipoles 140 to 900. The telescope has operated at the Amundsen-Scott South Pole research station since 2000 January. The telescope was retrofit as a polarimeter during the 2000--2001 austral summer, and throughout the 2001 and 2002 austral winters has made observations of the CMB with sensitivity to all four Stokes parameters. The telescope performance has been extensively characterized through observations of artificial sources, the Moon, and polarized and unpolarized Galactic sources. In 271 days of observation, DASI has differenced the CMB fluctuations in two fields to an rms noise level of 2.8 uK.

Trojan horse or horn of plenty? Integrative technology assessment to analyse impacts, benefits and trade-offs of Carbon Capture and Storage, CCS
Creators: name: Flüeler, Thomas
Publisher: name: ETH Zurich
Year: 2024

description: Science and society recognise the climate crisis as a serious problem; humankind is, nevertheless, still pursuing a path with high greenhouse gas, esp. carbon dioxide, CO2 emissions to the atmosphere. Barriers to effective reductions exist at political, institutional and individual levels. Incentives, trading and enforcement mechanisms are weak or not in place, and large-scale lifestyle changes towards sustainable development are out of sight. In such a wicked situation, the characteristics of carbon capture and storage, CCS seem attractive, negative emission paths even seem indispensable to reach the 1.5°C goal. In their “Special report on global warming of 1.5˚C”, the Intergovernmental Panel on Climate Change, IPCC found that three out of the four pathways to reaching net-zero by 2050 involve the use of CCS (IPCC 2018). It promises a – relatively – quick and technical, narrowly located but high-potential solution with no need for extensive efficiency improvement in dispersed facilities, equipment, appliances or “software” such as institutions and behaviour. The involved dimensions are manifold – there is no “one” method for analysis. Instead, cross-disciplinary investigations allow drawing lessons from various controversial long-term environmental issues – vital before fully embarking on this route. IPCC themselves admitted in their recent mitigation report in climate change that the “[i]mplementation of CCS currently faces technological, economic, institutional, ecological-environmental and socio-cultural barriers” (IPCC 2022, 28).

In order to become an efficient, effective and sustainable jigsaw piece of a low-carbon system transition, CCS has to prove its suitability. CCS embodies the tension between the advantage of a short-term “quick fix” and the disadvantages posed by the risk of long-term leakage and, from a technology policy perspective, the danger of perpetuating carbon lock-in. The present approach to scrutinise this question, laid out in Flüeler 2023, is a combination of disciplines and perspectives from systems theory, risk assessment, technology assessment and management. Six criteria address issues proven to be crucial in technology policy debates: 1. Need for deployment and benefits compared to competing technological options, 2. Total-system analysis and safety concept, 3. Internationally harmonised regulation and control, 4. Economic aspects, 5. Implementation along technology readiness levels, and 6. Societal issues. It conceptually and analytically serves to tackle the question raised 16 years ago whether CCS indeed is a “Trojan horse or a horn of plenty” (de Coninck 2008).

description: N66/NGC346 is the largest and brightest HII region in the Small Magellanic Cloud and contains at least one known supernova remnant SNR0057-7226. Optical emission from the remnant is overwhelmed by the bright photoionized emission from the nebula, but the remnant has been detected by way of far ultraviolet absorption lines. Here we present data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite showing strong OVI and CIII emission from a position at the edge of SNR0057-7226. We also present high-resolution, long-slit Halpha spectra across N66 showing high- and low-velocity emission corresponding closely to the X-ray boundaries of the supernova remnant. We use these FUV and optical data to determine the physical parameters of the shock and interaction geometry with N66. We find that ionizing photons from the many massive cluster stars nearby likely affect the ionization balance in the post-shock gas, hindering the production of lower-ionization and neutral species. We discuss the importance and inherent difficulty of searching for supernova remnants in or near bright HII regions and suggest that the far ultraviolet provides a viable means to discover and study such remnants.

Accounting for growth in global agriculture

description: Rising prices of agricultural commodities have renewed concerns about constraints to agricultural productivity. To assess productivity trends, total factor productivity (TFP) is generally preferred to partial productivity indexes as an indicator of technical and efficiency changes because it is more closely related to the unit costs of production. But measuring TFP is demanding of data, and developing comprehensive and comparable indexes of international agricultural TFP has been challenging. This study proposes a growth accounting approach, using FAO data on quantity changes in inputs and outputs and aggregating input changes using cost shares derived from other sources, as a consistent way of constructing agricultural TFP indexes for world agriculture. This produces aggregate growth rates for agricultural output, input and TFP at the country, regional and global levels. Results suggest that the rate of agricultural TFP growth accelerated in recent decades, especially in developing countries. Most regions of the world now rely on productivity-based growth rather than resource-based growth to raise agricultural output.

Associated production of SM Higgs with a photon in type-II seesaw models at the ILC

description: We consider the production of a single Standard Model (SM) Higgs boson ($h^0$) in association with a photon at the future Linear collider (LC) in the context of a type-II seesaw model. The type-II seesaw model extends the SM particle content by adding one triple Higgs where its Higgs coupling is a key parameter of the scalar potential triggering the electroweak symmetry-breaking mechanism in the SM. It is a well motivated model since it provides neutrino masses and mixing. The LC presents a particularly interesting possibility to probe Higgs couplings due to the clean beams in the initial state. We study the one loop processes $e^+e^- \to h^0γ$ and $e^-γ\to e^- h^0$, we show that it is possible to correlate the total cross section predictions with the couplings $h^0γγ$ and $h^0γZ$ which are sensitive to the presence of singly and doubly charged Higgs. For parameter points allowed by the current experimental constraints, our numerical results show that the effect of $H^\pm$ and $H^{\pm\pm}$ can be as large as $\pm$ 25\% with respect to the SM predictions. For both processes, we also present differential cross section for different center of mass energy.

description: Reviews the above mentioned book which contains a social history of the Gunggari Aboriginal group located in South West Queensland and which outlines their struggle for land rights. Following the commencement of the British settlement of Australia in 1788 and the proclamation then of British Sovereignty over New South Wales (which at that time included the area of the subsequent state of Queensland), the land rights of Australian Aborigines were not recognized. Legal recognition has only been given to prior land ownership of some Australian Aboriginal groups in recent decades. The extent to which they have been able to obtain legal restitution of these rights has varied considerably and also the economic consequences for indigenous groups have been very unequal. The process of having their previous land rights legally recognized (and salvaging whatever rights have not been extinguished) has been a major struggle for Aboriginal groups. This book provides a valuable and balanced case study of social dynamics of this process. It is considered that this book deserves the attention of all who are interested in Indigenous affairs, both general readers and specialists in Australia, as well as elsewhere.
