description: We present CCD VR_C observations of 6 distant comets located at heliocentric distances of 3.4--7.2 AU. Time-series data were obtained on three nights in July, 2000 covering 16 hours. Each comet was observed after the perihelion, when a lower activity was expected. Contrary to expectation, we found well-defined circular comae and extended tails visible out to a few (3-5) arcminutes. We detected a quasi-cyclic light variation of C/1999 J2, while C/1999 N4 showed some hints of a more complex variation. C/2000 K1 was constant to +/-0.04 mag during the observing run. The standard V and R_C data were used to estimate nuclear diameters, while the colour indices implied a slighly reddish (V-R=0.68, C/2000 K1), a neutral (V-R=0.47, C/1999 N4) and a slightly bluish (V-R=0.25, C/1999 J2) coma. Simple fits of the surface brightness distributions are also presented enabling order of magnitude estimates of nuclear radii. Beside the time-series observations, further single-shot observations of three faint comets are briefly described.

description: The proton-proton parity-violating longitudinal asymmetry is calculated in the lab-energy range 0--350 MeV, using a number of different, latest-generation strong-interaction potentials--Argonne V18, Bonn-2000, and Nijmegen-I--in combination with a weak-interaction potential consisting of rho- and omega-meson exchanges--the model known as DDH. The complete scattering problem in the presence of parity-conserving, including Coulomb, and parity-violating potentials is solved in both configuration- and momentum-space. The predicted parity-violating asymmetries are found to be only weakly dependent upon the input strong-interaction potential adopted in the calculation. Values for the rho- and omega-meson weak coupling constants $h^{pp}_ρ$ and $h^{pp}_ω$ are determined by reproducing the measured asymmetries at 13.6 MeV, 45 MeV, and 221 MeV.

description: Steel is usually cleaned by acid solutions before its application in various industries. Such a treatment increases the possibility of steel corrosion, making the use of inhibitors in the cleaning bath indispensable. On this basis, the introduction of novel, efficient corrosion inhibitors is always of great importance. In the present research, three series of hydrazone Schiff bases were synthesized and investigated as corrosion inhibitors for mild steel in 1.0 M HCl solution. Corrosion experiments included weight loss, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PDP), which were performed at different temperatures. SEM images provided the surface analysis of the steel sheets in the absence and presence of the inhibitors. The prepared Schiff bases exhibited inhibition efficiencies higher than 92% at an optimum concentration of 0.01 M. The quantitative structure–activity relationship (QSAR) was used to obtain a correlation between the inhibition efficiency and the quantum chemical parameters of the inhibitors.

description: We investigate the number counts, clustering, morphology and radio/X-ray emission of extremely red objects (EROs), defined as galaxies with R-K>5.0. This criterion will select old, passive ellipticals at z>0.9. To K=21 we identify a total of 158 EROs in 81.5 sq. arcmin. The ERO number counts are lower than predicted by a pure luminosity evolution model, but higher than predicted by current CDM-based hierarchical models. They can be fitted by a combination of moderate merging with a decrease with redshift in the comoving number density of passive galaxies. We investigate the angular correlation function and find that the EROs have a much higher correlation amplitude than full K-limited samples of galaxies. This implies that the intrinsic clustering of EROs is stronger than that of present-day E/S0 galaxies. We estimate the comoving correlation radius as 10-13 Mpc. We estimate seeing-corrected angular sizes and morphological types for a K<19.5 subsample (31 galaxies), and find a 3:2 mixture of bulge and disk profiles. 1/4 appear to be interacting, disturbed or irregular. The angular sizes of the bulge-profile EROs are consistent with passively evolving ellipticals at 0.9

description: We present local velocity measurements in emulsions under shear using heterodyne Dynamic Light Scattering. Two emulsions are studied: a dilute system of volume fraction $ϕ=20$ % and a concentrated system with $ϕ=75$ %. Velocity profiles in both systems clearly show the presence of wall slip. We investigate the evolution of slip velocities as a function of shear stress and discuss the validity of the corrections for wall slip classically used in rheology. Focussing on the bulk flow, we show that the dilute system is Newtonian and that the concentrated emulsion is shear-thinning. In the latter case, the curvature of the velocity profiles is compatible with a shear-thinning exponent of 0.4 consistent with global rheological data. However, even if individual profiles can be accounted for by a power-law fluid (with or without a yield stress), we could not find a fixed set of parameters that would fit the whole range of applied shear rates. Our data thus raise the question of the definition of a global flow curve for such a concentrated system. These results show that local measurements are a crucial complement to standard rheological tools. They are discussed in light of recent works on soft glassy materials.

description: Food and nutrition security in high income countries is challenged by financial crisis, austerity policies, unemployment and immigration and a growing number of people, also from those segments of population once considered secure, seek food assistance. Emergency food initiatives are developed by a diverse range of actors through various instruments and approaches. Alongside the difficulties of this sector – lack of control over donation, inability to ensure nutritional requirements, stigmatization, dependency on volunteer work – new challenges emerge from welfare expenditure cuts, the reorganization of EU funds for the most deprived (FEAD) and from the spreading of surplus food recovery practices. Based on a preliminary analysis on food assistance practices in Tuscany (Italy), it emerged that operators involved in food assistance activities are re-thinking their role to address changing needs: private companies are increasingly involved in food assistance operations and adjust their activities and strategies accordingly; public institutions re-think the boundaries between charitable assistance, welfare system and market-based food system. How is food assistance re-thinking its role to deal with the challenges posed by the current context of change? This work combines the strengths of two approaches by developing back-casted pathways and testing them within explorative scenarios, that describe plausible future contexts. The aim is to explore the feasibility of transformative change in different scenarios. We apply a participatory scenario approach, as a tool for future-oriented thinking, mindful of future uncertainty and the multidimensional scope required to look at planning context. Results comprise the definition of shared priority themes: governance, education and a person’s centered approach. For each, key objectives were identified and back-casted plans of actions were developed, considering a suitable time frame. These plans were then tested within and across four different scenarios of the food assistance system. The methodology provides a promising learning tool to engage with stakeholders and foster a creative future oriented thinking approach to food assistance system’s vulnerability and resilience.

description: We discuss new high-resolution (6.7 km/s) spectra of the associated absorption lines (AALs) in the radio-loud quasar 3C 191. The measured AALs have ionizations ranging from Mg I to N V, and multi-component profiles that are blueshifted by ~400 to ~1400 km/s relative to the quasar's broad emission lines. Excited-state absorption lines of Si II* and C II* imply volume densities of ~300 cm^-3 and a nominal distance from the quasar of 28 kpc (assuming photoionization). The total column density is N_H ~ 2 x 10^20 cm^-2. Surprisingly, the absorber only partially covers the quasar emission source along our line of sight. We propose a model for the absorber in which pockets of dense neutral gas are surrounded by bigger clouds of generally lower density and higher ionization. This outflowing material might be leftover from a blowout associated with a nuclear starburst, the onset of quasar activity, or a past broad absorption line (BAL) wind phase.

title: Effect of combination transversus abdominis and rectus sheath plane block on post-operative opioid requirement after laparoscopic appendicectomy

description: Background Laparoscopic appendicectomy is the gold standard management of acute appendicitis. Pain post laparoscopic appendicectomy is common, with multifactorial aetiology. As a routine, local anaesthetic is injected to port sites at the time of laparoscopy, to reduce post-operative pain. Opioid drugs are also commonly prescribed to treat post-operative pain. It is hypothesised that injecting local anaesthetic as a transversus abdominis plane (TAP) block in combination with a rectus sheath (RS) block, will reduce post-operative opioid requirement in patients post laparoscopic appendicectomy when compared with port site infiltration of local anaesthetic. Method A prospective quasi-randomised controlled trial was performed on all patients who underwent laparoscopic appendicectomy at the Gold Coast University Hospital between April 2022 and February 2023. Patients were allocated to receive either local anaesthetic to port sites or local anaesthetic injected as a TAP and RS block. Allocation was performed according to the patient's week of operation - in an alternating fashion. Week A received TAP and RS blocks and Week B received local anaesthetic to port sites. 20ml of ropivacaine 0.75% was used for port site infiltration, and the same diluted to 40ml (with 20ml of 0.9% sodium chloride) was used for TAP and RS blocks. Post-operative opioid use, time to rescue opiate use, antiemetic use (as a surrogate marker for post-operative nausea and vomiting (PONV)), and post-operative length of stay (LOS) were recorded and analysed.

description: Morphometrics and meristics are measurable and countable traits, respectively, that are under simultaneous control by genetic and/or environmental factors. Resolving morphometric and meristic spatial variation can be a useful technique for identifying population structure and connectivity. The present study investigated morphometric and meristic character variation within three flounder species, sand flounder (Rhombosolea plebeia), greenback flounder (R. tapirina), and yellowbelly flounder (R. leporina) in New Zealand, predominantly in the South Island. Four morphometric measurements and two meristic characters were obtained from 857 juvenile flounder, standardised, and analysed. Consistent with a previous genetic analysis, the differentiation of morphometric and meristic characters supported the idea that sand flounder populations north and south of 42o S were reproductively isolated, and although statistically non-significant, there was an indication that yellowbelly flounder collected from Lake Ellesmere and Orowaiti Lagoon may have been reproductively isolated. Only juvenile sand flounder and greenback flounder were collected in the tidal reaches of estuaries throughout east Otago and the populations are considered undifferentiated based on intra-species morphometric and meristic characters. Our results demonstrated that the influence of environmental variation and adaptive physiology of juvenile flounder likely contributed to the morphometric and meristic variation of individuals among estuaries and years.

description: In this paper, we present a novel method for measurably adjusting the semantics of text while preserving its sentiment and fluency, a task we call semantic text exchange. This is useful for text data augmentation and the semantic correction of text generated by chatbots and virtual assistants. We introduce a pipeline called SMERTI that combines entity replacement, similarity masking, and text infilling. We measure our pipeline's success by its Semantic Text Exchange Score (STES): the ability to preserve the original text's sentiment and fluency while adjusting semantic content. We propose to use masking (replacement) rate threshold as an adjustable parameter to control the amount of semantic change in the text. Our experiments demonstrate that SMERTI can outperform baseline models on Yelp reviews, Amazon reviews, and news headlines.

description: There has been continuing interest in Bayesian regressions in which no parametric assumptions are imposed on the error distribution. In this study, we consider semiparametric Bayesian nonlinear regression models. We do not impose a parametric form for the likelihood function. Instead, we treat the true density function of error terms as an infinite-dimensional nuisance parameter and estimate it nonparametrically. Thereafter, we conduct a conventional parametric Bayesian inference using MCMC methods. We derive the asymptotic properties of the resulting estimator and identify conditions for adaptive estimation, under which our two-step Bayes estimator enjoys the same asymptotic efficiency as if we knew the true density. We compare the accuracy and coverage of the adaptive Bayesian point and interval estimators to those of the maximum likelihood estimator empirically, using simulated and real data. In particular, we observe that the Bayesian inference may be superior in numerical stability for small sample sizes.

description: Der Einzug der rechtspopulistischen und teilweise rechtsextremistischen Alternative für Deutschland in den Deutschen Bundestag, hat das politische Klima verändert und stellt auch den Journalismus vor neue Herausforderungen. Die vorliegende Arbeit untersucht, wie Politikjournalist*innen Fernsehinterviews mit AfD-Politiker*innen führen. Hierfür wurden leitfaden-basierte Experteninterviews mit neun Experten aus den Bereichen der politischen Interviewführung vor und hinter der Kamera sowie Seminaren zur Interviewführung mit Rechtspopulist*innen geführt. Die Untersuchungsergebnisse werden mit Hilfe einer qualitativen Inhaltsanalyse in Anlehnung an Mayring ermittelt. Zentrale Ergebnisse dieser Arbeit sind, dass es zwar keiner grundsätzlich ‚spezifischen‘ Interviewführung bei AfD-Politiker*innen bedarf, die Vorbereitung darauf allerdings weitaus umfangreicher sein muss. Politikjournalist*innen müssen sich in Bereichen des Rechtsextremismus, der Rhetorik der Rechten und rechtspopulistischem Framing weiterbilden und auf Anfeindungen und Verleumdung von Fakten von AfD-Politiker*innen vorbereitet sein. Außerdem wird aus der Untersuchung deutlich, dass es beispielsweise einen großen Unterschied macht, ob Politikjournalist*innen AfD-Interviews vor oder hinter der Kamera führen. Die Untersuchungsteilnehmer sind sich darin einig, dass durch die exorbitante, mediale Beobachtung und die gegensätzlichen Erwartungshaltungen der Öffentlichkeit, Politikjournalist*innen unter einem erhöhten Druck bei Interviews mit AfD-Politiker*innen stehen. Dadurch wird einem Fernsehinterview mit AfD-Politiker*innen eine Art Sonderstatus zugeschrieben und es hebt sich somit auch immer von Fernsehinterviews mit Politiker*innen anderer Parteien ab.

description: Background: Phenotypic variation within species challenges the identification of meaningful taxonomic units and the quantification of evolutionarily relevant biodiversity. Aims: We studied usefulness of the present taxonomic classification of species and subspecies within Festuca rubra complex. Methods: We categorised F.rubra s.l. plants collected from natural populations across Europe such as the endemic species of F. rothmaleri and F. rubra subspecies (subsp. rubra and arctica) or between-subspecies hybrids (arctica × rubra). The plants were grown in a common garden, which was followed by an examination of variation in regard to 17 morphological traits, ploidy levels, nuclear ribosomal DNA, and chloroplast DNA. Results: Phenotypic and cpDNA markers demonstrated stronger differentiation between geographic regions than between species or subspecies. Of the morphological traits, only lemma hairiness distinguished between F.rubra subspecies. Ploidy level varied within the F. rothmaleri and F.rubra subspecies. cpDNA and nrDNA markers showed no genetic differentiation among the F. rubra subspecies and their hybrids but clustered F. rubra taxa and F.rothmaleri as separate groups. Several additive polymorphic sites in nrDNA sequences indicated hybridisation in the F. rubra taxa. Conclusion: Commonly used traits may not be reliable in determining evolutionary relevant taxonomic entities within F.rubra complex.

description: We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these shocks and the casual effects. We show that returns to investment in agriculture, small and medium enterprises and human capital differ significantly from year to year. We also show how returns to investments interact with specific aggregate shocks, and estimate the parameters of the distributions of these shocks. We show how to use these estimates to appropriately widen estimated confidence intervals to account for aggregate shocks.

description: This work defines a procedure to assess the socio-economic and environmental sustainability of agricultural systems with a particular attention to conventional and organic farming. Firstly, a mathematical programming model calculates the different multi-dimensional outcomes of Italian farms depending on various levels of prices affecting organic products. Those outcomes are the input data for a fuzzy multi-criteria analysis, which processes the various criteria, takes into account different sets of weights for criteria, and, by a ranking of price scenarios, identifies the most desirable and the least desirable level of prices for five groups of regions. The method adopted proves to be sensitive to geographical location and different perspectives. In particular, when the farmers’ set of weights is adopted, the highest level of prices represents the most desirable scenario in all groups of regions. On the other side, in all other sets of weights, the lowest level of prices seems to be the most preferable scenario for North-Western regions.

description: Invasive species can significantly alter invaded ecosystems. In this study, we report the presence of two invasive species, the poeciliid fish Poecilia reticulata and the gastropod Melanoides tuberculata, in three isolated springs from the coast of the Atacama Desert in Antofagasta city, northern Chile. Both species were identified through diagnostic morphological features and phylogenetic analysis. This is the first confirmed record of P. reticulata in natural ecosystems of Chile. The finding of M. tuberculata represents the first record of the species in the Antofagasta Region, and the third in the country. Considering the well-documented adverse effects of both species on invaded ecosystems and their high potential for spread, we recommend the prompt implementation of mitigation measures. These should focus on the direct mechanical removal of these species, given the relatively straightforward sampling process and the relatively small size of the springs. Such measures would significantly contribute to the preservation of native species, particularly those categorized as vulnerable.

description: We experimentally test the impact of expanding access to basic bank accounts in Uganda, Malawi, and Chile. Over two years, 17%, 10%, and 3% of treatment individuals made five or more deposits, respectively. Average monthly deposits for them were at the 79th, 91st, and 96th percentiles of baseline savings. Survey data show no clearly discernible intention-to-treat effects on savings or any downstream outcomes. This suggests that policies merely focused on expanding access to basic accounts are unlikely to improve welfare noticeably since impacts, even if present, are likely small and diverse
Discovery of a Second High Frequency QPO from the Microquasar GRS 1915+105

description: We report the discovery in archival Rossi X-ray Timing Explorer (RXTE) data of a 40 Hz quasiperiodic oscillation (QPO) in the hard X-ray flux from the galactic microquasar GRS 1915+105. The QPO is detected only in the hard X-ray band above 13 keV and was discovered in observations in which the previously known 67 Hz QPO is present. The 40 Hz QPO has a typical rms amplitude of 2 % in the 13 - 27 keV band, and a width of about 8.5 Hz (FWHM). We show that the 67 and 40 Hz QPOs are detected in the same observations in July and November, 1997. However, the QPO is not detected in observations from April, May and June, 1996 in which the 67 Hz QPO was first discovered. The frequency of the 67 Hz QPO is significantly higher in the 1997 observations by about 5 % compared with the 1996 data. The identification of the 40 Hz QPO makes GRS 1915+105 the second black hole binary to show a pair of simultaneous high frequency QPO (the other being GRO J1655-40). The similarities between the properties of the 67 Hz QPO in GRS 1915+105 and the recently discovered 450 Hz QPO in GRO J1655-40 suggest that the pairs of frequencies in these systems may be produced by the same physical mechanism, with the frequency differences between the two being likely due to different black hole masses in the two systems. We discuss the implications of our result for the mass and spin of GRS 1915+105 as well as for models of X-ray variability in black holes and neutron stars.

Limits on amplifiers of natural selection under death-Birth updating

description: The fixation probability of a single mutant invading a population of residents is among the most widely-studied quantities in evolutionary dynamics. Amplifiers of natural selection are population structures that increase the fixation probability of advantageous mutants, compared to well-mixed populations. Extensive studies have shown that many amplifiers exist for the Birth-death Moran process, some of them substantially increasing the fixation probability or even guaranteeing fixation in the limit of large population size. On the other hand, no amplifiers are known for the death-Birth Moran process, and computer-assisted exhaustive searches have failed to discover amplification. In this work we resolve this disparity, by showing that any amplification under death-Birth updating is necessarily \emph{bounded} and \emph{transient}. Our boundedness result states that even if a population structure does amplify selection, the resulting fixation probability is close to that of the well-mixed population. Our transience result states that for any population structure there exists a threshold $r^*$ such that the population structure ceases to amplify selection if the mutant fitness advantage $r$ is larger than $r^\star$. Finally, we also extend the above results to $δ$-death-Birth updating, which is a combination of Birth-death and death-Birth updating. On the positive side, we identify population structures that maintain amplification for a wide range of values $r$ and $δ$. These results demonstrate that amplification of natural selection depends on the specific mechanisms of the evolutionary process.
Agri-environmental measures and farmers’ rent: evaluating the potential contribution of auctions to increase the efficiency of Agri-environmental schemes in Emilia-Romagna (Italy)

description: This work compares the cost-effectiveness of a simulated auction model (AM) with that of classical payment mechanisms as a marginal flat rate payment (MFR) and average flat rate payment (FR). The study provide an extension of the one-shot budget constrained auction model (BC) first introduced by Latacz-Lohmann and Van Der Hamsvoort (1997), and subsequently by Viaggi et al. (2008) and Glebe (2008). In this formulation, the model allows farmers to offer multi-dimensional bid as a combination of payment and a measure of a share of their land to commit to a hypothetical agri-environmental measure (AEM). The results show that the performance of the auction (i.e. 7.5 % and 27 % of the total UAA of the sample) is always located halfway between that of FR (i.e. 5% and 21 % of the total UAA of the sample) and that of MFR (i.e. 17% and 100% of the total UAA of the sample). According with Schillizzi and Latacz-Lohmann (2007) the flat rate option provides an amount of rents that is one and a half the auction’s rents with a lower budget and around two times greater with the higher budget level. The results confirm that the auction has the potential to reduce farmers’ information rent when compared with uniform policy instruments. However, the scale of saving depends crucially on auction design hypotheses and farmers' expectation about the maximum acceptable bid cap. The results of this research while attempting to provide a useful empirical exploration of auction theory cannot provide a comprehensive solution in most real world settings. However, it can contribute to feed the debate at EU policy level about the role of tendering instruments in agri-environmental programs to reduce the inefficiency related to the actual agri-environmental payments.
