subject: Human impacts of climate change and human adaptation

description: In many developing countries, livestock play a crucial role in improving the standard of living for poor rural households. However, the lack of, or failure to adopt, effective and modern climate change mitigation and adaptation techniques can have a significant negative impact on productivity. Livestock herders, especially the smaller ones, in developing nations are particularly vulnerable due to their locations and the socioeconomic situations of these countries. Their lack of resources makes it difficult for them to adapt to this threat. The various adaptation strategies employed by farmers in rural Zimbabwe are prone to contribute to a significant reduction in livestock loss and consequently poverty alleviation. This study employed a qualitative method wherein thirteen participants from four villages of Mutoko District took part. Participants were selected through purposive sampling and data was collected through in-depth interviews and analysed through thematic content analysis. The study found that a wide array of strategies has been put in place in order to deal with the loss of cattle in the district. These strategies include improved grazing management practises, provision of medical facilities such as disease control precaution, diversification of livestock, and adoption of improved/stress-tolerant livestock.

description: We report the numerical evidence of a new state of active turbulence in confined domains. By means of extensive numerical simulations of the Toner-Tu-Swift-Hohenberg model for dense bacterial suspensions in circular geometry, we discover the formation a stable, ordered state in which the angular momentum symmetry is broken. This is achieved by self-organization of a turbulent-like flow into a single, giant vortex of the size of the domain. The giant vortex is surrounded by an annular region close to the boundary, characterized by small-scale, radial vorticity streaks. The average radial velocity profile of the vortex is found to be in agreement with a simple analytical prediction. We also provide an estimate of the temporal and spatial scales of a suitable experimental setup comparable with our numerical findings.

Memory and Performance in Dublin’s Art Scenario: Brian O’Doherty and Sebastian Barry

description: In 2008 Brian O’Doherty buried his alter ego, Patrick Ireland, in Dublin, as a consequence of peace having been restored in Northern Ireland. “We are burying hate”, said the New York artist of Irish origin, “it’s not often you get the chance to do that”. With Patrick’s masked effigy lain in a coffin the memory of past tragic times was spectacularized, and paved the way to a more luminous future. In the previous summer the staging of Sebastian Barry’s The Pride of Parnell Street focuses on a episode of domestic violence by a Dublin fellow on the occasion of “Italia ’90” world cup. By staging the anxieties and confronting the fears of the two protagonists, man and wife, who have since then lived separately, in a one-to-one dialogue disguised as a monologue, both the woman and the man end up recovering one’s freedom and one’s pride, respectively. Through the analysis of O’Doherty’s and Barry’s performance, the essay shows how the contemporary artistic and multicultural global ferments, and the new ethnic dimension since the rising of the Celtic Tiger have brought changes to the social texture of a nation marred by forced emigration. Also, a 2007 film directed by John Carney, Once, proposes, through the story of an Irish Guy and a Czech migrant Girl, a social cross section that could work in Dublin as well as, thanks to the new global cultural flows, in any other of today’s ethnoscapes and ideoscapes.

description: We introduce and study new invariants associated with Laplace type elliptic partial differential operators on manifolds. These invariants are constructed by using the off-diagonal heat kernel; they are not pure spectral invariants, that is, they depend not only on the eigenvalues but also on the corresponding eigenfunctions in a non-trivial way. We compute the first three low-order invariants explicitly.

description: The purpose of this study is to calculate the appropriate market isolation amount of rice, which is a main part of government’s stabilization policy of rice prices. For this purpose, we improved the existing rice price forecasting model. The improved model corrected the possibility of systematic measurement errors in the statistical data, and explicitly considered the psychological influences of market participants and the long-term trend of rice prices. Using the improved model, this study derives forecasts of rice prices based on the scenario of isolation amount in the 2017 rice market. Finally, we derived the appropriate amount of market isolation to be used directly in government’s rice market stabilization policy.

description: We study the pairing properties of the two-dimensional $t$-$t'$-$t''$-$J$ model, where $t'$ and $t''$ are second and third neighbor hoppings, at a doping level $x\approx0.1$. Recent studies of the $t$-$t'$-$J$ model find strong pairing for $t'>0$, associated with electron doping, but an absence of pairing for $t'<0$ associated with hole doping. This is in contrast to the cuprates, where the highest transition temperatures appear for hole doping. Model parameterizations for the cuprates estimate a $t''$ comparable to $t'$, which, in principle, might fix this discrepancy. However, we find that it does not; we observe a suppression of pairing for the hole-doped system ($t'<0, t''>0$) while for the electron-doped system ($t'>0, t''<0$) $d$-wave pairing is robust. Extended hoppings appear to be insufficient to make the one-band $t$-$t'$-$J$ model capable of describing the pairing in the hole doped system.

In the state-of-the-art review on metamodelling, we review approaches, abstractions, and tools for metamodelling, evaluate them with respect to their expressivity, investigate what role(s) metamodels may play at run-time and how semantics can be assigned to metamodels and the domain specific modeling languages they could define. In the emerging challenges section on metamodelling we highlight research issues regarding the management of complexity, consistency, and evolution of metamodels, and how the semantics of metamodels impacts each of these.

description: An analytical formula for electrical impedance between an adherent living cell and sensor substrate measured using a microelectrode is presented for the first time. Previously-reported formula has been applicable only for the case where many cells are on a large electrode. In contrast, our formula is valid even when a microelectrode smaller than the cell size is underneath the cell, which is often the case for the state-of-the-art single-cell analysis. Numerical simulations for verifying the accuracy of our formula reveals that the discrepancies between the theoretical impedances calculated by our formula and numerical simulation results are negligibly small. Our formula will be useful for describing cell-substrate impedance properties in equivalent circuit model analysis or sensor design optimizations.

description: The complementary DNA (cDNA) sequence is considered to be the magic biometric technique for personal identification. In this paper, we present a new method for cDNA recognition based on the artificial neural network (ANN). Microarray imaging is used for the concurrent identification of thousands of genes. We have segmented the location of the spots in a cDNA microarray. Thus, a precise localization and segmenting of a spot are essential to obtain a more accurate intensity measurement, leading to a more precise expression measurement of a gene. The segmented cDNA microarray image is resized and it is used as an input for the proposed artificial neural network. For matching and recognition, we have trained the artificial neural network. Recognition results are given for the galleries of cDNA sequences . The numerical results show that, the proposed matching technique is an effective in the cDNA sequences process. We also compare our results with previous results and find out that, the proposed technique is an effective matching performance.

description: Risk-based authentication (RBA) aims to protect users against attacks involving stolen passwords. RBA monitors features during login, and requests re-authentication when feature values widely differ from previously observed ones. It is recommended by various national security organizations, and users perceive it more usable and equally secure than equivalent two-factor authentication. Despite that, RBA is still only used by very few online services. Reasons for this include a lack of validated open resources on RBA properties, implementation, and configuration. This effectively hinders the RBA research, development, and adoption progress. To close this gap, we provide the first long-term RBA analysis on a real-world large-scale online service. We collected feature data of 3.3 million users and 31.3 million login attempts over more than one year. Based on the data, we provide (i) studies on RBA's real-world characteristics, and its configurations and enhancements to balance usability, security, and privacy, (ii) a machine learning based RBA parameter optimization method to support administrators finding an optimal configuration for their own use case scenario, (iii) an evaluation of the round-trip time feature's potential to replace the IP address for enhanced user privacy, and (iv) a synthesized RBA data set to reproduce this research and to foster future RBA research. Our results provide insights on selecting an optimized RBA configuration so that users profit from RBA after just a few logins. The open data set enables researchers to study, test, and improve RBA for widespread deployment in the wild.

Softening of edges of solids by surface tension

description: Surface tension tends to minimize the area of interfaces between pieces of matter in different thermodynamic phases, be they in the solid or the liquid state. This can be relevant for the macroscopic shape of very soft solids, and lead to a roughening of initially sharp edges. We calculate this effect for a neo-Hookean elastic solid, with assumptions corresponding to actual experiments, namely the case where an initially sharp edge is rounded by the effect of surface tension felt when the fluid surrounding the soft solid (and so surface tension) is changed at the solid/liquid boundary. We consider two opposite limits where the analysis can be carried to the end, the one of a shallow angle and the one of a very sharp angle. Both cases yield a discontinuity of curvature in the state with surface tension although the initial state had a discontinuous slope.

description: Astronomers occasionally detect an object having unexpected shape, unexplainable photometry, or unprecedented spectra that are inconsistent with our contemporary knowledge of the universe. Upon careful assessment, many of these anomalies are discarded as mere noise, contamination, or faulty analysis. But some anomalies survive scrutiny to yield new astronomical objects and physical processes. Examples of validated anomalies include quasars, pulsars, and periodic Doppler shifts of Sun-like stars caused by the gravitational pull of orbiting planets. Other anomalies persist as mysteries, including Fast Radio Bursts, dark energy, 'Oumuamua as an alien spaceship, and simultaneously vanishing stars. Advanced technological life may present astronomers with anomalies that require carefully designed observations from multiple vantage points simultaneously and with real-time spectroscopy.

description: In the low-mass regime, it is found that the gas-phase abundances of C-bearing molecules in cold starless cores rapidly decrease with increasing density, as the molecules form mantles on dust grains. We study CO depletion in 102 massive clumps selected from the ATLASGAL 870 micron survey, and investigate its correlation with evolutionary stage and with the physical parameters of the sources. Moreover, we study the gradients in [12C]/[13C] and [18O]/[17O] isotopic ratios across the inner Galaxy, and the virial stability of the clumps. We use low-J emission lines of CO isotopologues and the dust continuum emission to infer the depletion factor fD. RATRAN one-dimensional models were also used to determine fD and to investigate the presence of depletion above a density threshold. The isotopic ratios and optical depth were derived with a Bayesian approach. We find a significant number of clumps with a large fD, up to ~20. Larger values are found for colder clumps, thus for earlier evolutionary phases. For massive clumps in the earliest stages of evolution we estimate the radius of the region where CO depletion is important to be a few tenths of a pc. Clumps are found with total masses derived from dust continuum emission up to ~20 times higher than the virial mass, especially among the less evolved sources. These large values may in part be explained by the presence of depletion: if the CO emission comes mainly from the low-density outer layers, the molecules may be subthermally excited, leading to an overestimate of the dust masses. CO depletion in high-mass clumps seems to behave as in the low-mass regime, with less evolved clumps showing larger values for the depletion than their more evolved counterparts, and increasing for denser sources. The C and O isotopic ratios are consistent with previous determinations, and show a large intrinsic scatter.

description: The search for a particle dark matter signal in terms of radiation produced by dark matter annihilation or decay has to cope with the extreme faintness of the predicted signal and the presence of masking astrophysical backgrounds. It has been shown that using the correlated information between the dark matter distribution in the Universe with the fluctuations of the cosmic radiation fields has the potential to allow setting apart a pure dark matter signal from astrophysical emissions, since spatial fluctuations in the radiation field due to astrophysical sources and dark matter emission have different features. The cross-correlation technique has been proposed and adopted for dark matter studies by looking at dark matter halos (overdensities). In this paper we extend the technique by focusing on the information on dark matter distribution offered by cosmic voids, and by looking specifically at the gamma-ray dark matter emission: we show that, while being underdense and therefore producing a reduced emission as compared to halos, nevertheless in voids the relative size of the cross-correlation signal due to decaying dark matter vs. astrophysical sources is significantly more favourable, producing signal-to-background ratios $S/B$ (even significantly) larger than 1 for decay lifetimes up to $2 \times 10^{30}$ s. This is at variance with the case of halos, where $S/B$ is typically (even much) smaller than 1. We show that forthcoming galaxy surveys such as Euclid combined with future generation gamma-ray detectors with improved specifications have the ability to provide a hint of such a signal with a predicted significance up to $5.7σ$ for galaxies and $1.6σ$ for the cosmic shear. The bound on the dark matter lifetime attainable exploiting voids is predicted to improve on current bounds in a mass range for the WIMP of $25\div900$ GeV.

description: As complex software and systems development projects need models as an important planning, structuring and development technique, models now face issues resolved for software earlier: models need to be versioned, differences captured, syntactic and semantic correctness checked as early as possible, documented, presented in easily accessible forms, etc. Quality management needs to be established for models as well as their relationship to other models, to code and to requirement documents precisely clarified and tracked. Business and product requirements, product technologies as well as development tools evolve. This also means we need evolutionary technologies both for models within a language and if the language evolves also for an upgrade of the models. This chapter discusses the state of the art in model management and evolution and sketches what is still necessary for models to become as usable and used as software.

description: We consider monitored quantum systems with a global conserved charge, and ask how efficiently an observer ("eavesdropper") can learn the global charge of such systems from local projective measurements. We find phase transitions as a function of the measurement rate, depending on how much information about the quantum dynamics the eavesdropper has access to. For random unitary circuits with U(1) symmetry, we present an optimal classical classifier to reconstruct the global charge from local measurement outcomes only. We demonstrate the existence of phase transitions in the performance of this classifier in the thermodynamic limit. We also study numerically improved classifiers by including some knowledge about the unitary gates pattern.

description: Negli ultimi venti anni il costo dei carburanti ha subito un notevole aumento con un significativo impatto sui costi del trasporto aeronautico. Inoltre, la Comunità Europea ha lanciato una politica di salvaguardia dell’ambiente in cui viviamo introducendo severi vincoli sull’emissione di gas inquinanti, quali l’anidride carbonica e gli ossidi di azoto e sui rumori emessi dai futuri aerei commerciali. Secondo le direttive emesse del gruppo ACARE (Advisory Council for Aerospace Research in Europe), gli aerei di nuova generazione dovranno avere caratteristiche tali da ridurre le emissioni di ossidi di azoto del 80 per cento e le emissioni di anidride carbonica del 50 per cento, mentre il rumore dovrà essere ridotto di 10 EPNdB (equivalente a dimezzare il rumore emesso da un aereo costruito con la tecnologia degli anni 2000). Da qui la forte richiesta dell’industria aeronautica per lo sviluppo di nuove tecnolgie mirate alla riduzione di qualsiasi forma di resistenza aerodinamica, cosicché da assicurare una consequente riduzione di carburante di di emissione di gas inquinanti. Si prevede che qualsiasi miglioramento aerodinamico ottenuto attraverso un miglioramento dell’efficienza dell’aereo abbia, come consequenza indiretta, un miglioramento dell’emissione di rumore. Infatti, l’eliminazione di qualsiasi separazione del flusso su componenti dell’aereo ottenuta migliorando per esempio l’integrazione pilone-ala-nacelle, come pure un miglioramento dell’integrazione dell’ala-fusoliera o del piano di coda-fusoliera, eccetera, abbia definitivamente effetti benefici sul rumore emesso. Ovviamente, il contributo maggiore al raggiungimento di questi obiettivi verrà dallo osviluppo di nuovi motori a basso consumo di carburante e, quindi, a bassa emissione di inquinanti, come nel caso del Geared Turbo Fan e del Counter Rotating Open Rotor, ma questo non sarà sufficiente. In questo contesto, ogni tecnologia capace potenzialmente di migliorare l’efficienza di un aereo ha ricevuto nuova attenzione. Tecniche di controllo del flusso come macro and micro vortex generators, riblets, synthetic jets, plasma actuators, unsteady blowing, steady and unsteady suction, micro-roughness elements, morphed structures, gurney flaps, winglets, trapped vortex, solo per citare alcune delle più popolari, hanno ricevuto un nuov impulso allo sviluppo e alla ricerca. Alcune di queste tecniche sono oggi comunemente usate su aerei, come per esempio i macro and micro vortex generators o come le winglets, mentre altre ancora hanno un basso Technological Readiness Level (TRL) per cui necessitano di ulteriori studi ed esperimenti.

description: Nonreversible Markov chains can outperform reversible chains in the Markov chain Monte Carlo method. Lifting is a versatile approach to introducing net stochastic flow in state space and constructing a nonreversible Markov chain. We present here an application of the lifting technique to the directed-worm algorithm. The transition probability of the worm update is optimized using the geometric allocation approach; the worm backscattering probability is minimized, and the stochastic flow breaking the detailed balance is maximized. We demonstrate the performance improvement over the previous worm and cluster algorithms for the four-dimensional hypercubic lattice Ising model. The sampling efficiency of the present algorithm is approximately 80, 5, and 1.7 times as high as those of the standard worm algorithm, the Wolff cluster algorithm, and the previous lifted worm algorithm, respectively. We estimate the dynamic critical exponent of the hypercubic lattice Ising model to be $z \approx 0$ in the worm and the Wolff cluster updates. The lifted version of the directed-worm algorithm can be applied to a variety of quantum systems as well as classical systems.
