description: We use data on the deep inelastic structure function F_2 in order to constrain the cross-section for scattering a colour dipole off a proton. The data seem to prefer parameterisations which include saturation effects. That is they indicate that the strong rise with energy of the dipole cross-section, which holds for small dipoles, pertains only for r < r_s(x) where r_s(x) decreases monotonically as x decreases. Subsequent predicitions for the diffractive structure function F_2^{D(3)} also hint at saturation, although the data are not really sufficiently accurate.

description: Este trabalho objetivou avaliar a eficiência técnica entre os produtores de leite da no PA Fruta D’Anta, no município de João Pinheiro, MG, no ano de 2006. Utilizou-se como instrumental analítico a Análise Envoltória de Dados (DEA), contando com uma amostra de 22 produtores assentados. Os resultados obtidos evidenciam que uma proporção significativa dos produtores são ineficientes tecnicamente. Observou-se, também, que todos os produtores ineficientes estão trabalhando sob retornos crescentes à escala, o que permite afirmar que estes poderiam aumentar seu lucro mais que proporcional quando aumentada à produção.-----------------The main objective of this paper was to evaluate the technical efficiency in 22 milk producers in the PA FrutaD’Anta, in the council de João Pinheiro, MG, during the period of 2006. The technical efficiency was evaluted through the Data Envelopment Analysis (DEA) technique. The results obtained show that there are still a significant proportion of inefficient farms. It was also observed that the inefficient producers are working on crescent returns to scale that admit so affirm that these could increase yours lucre more that proportional increasing yours production.

description: Optical materials with special optical properties are widely used in a broad span of technologies, from computer displays to solar energy utilization leading to large dataset accumulated from years of extensive materials synthesis and optical characterization. Previously, machine learning models have been developed to predict the optical absorption spectrum from a materials characterization image or vice versa. Herein we propose TLOpt, a transfer learning based inverse optical materials design algorithm for suggesting material compositions with a desired target light absorption spectrum. Our approach is based on the combination of a deep neural network model and global optimization algorithms including a genetic algorithm and Bayesian optimization. A transfer learning strategy is employed to solve the small dataset issue in training the neural network predictor of optical absorption spectrum using the Magpie materials composition descriptor. Our extensive experiments show that our algorithm can inverse design the materials composition with stoichiometry with high accuracy.

description: We have developed a wedge-loaded double-cantilever beam adhesion measurement set-up for thin films deposited on glass by sputtering. The test is described in details. Results on the Glass/sublayer/Ag/ZnO multilayer provide evidence that \SnOd or \TiOd perform better than ZnO as a sublayer. Then however, rupture within the multilayer shifts to the upper Ag/ZnO interface. The latter is shown to be tougher than the lower ZnO/Ag interface, an asymmetry due to non-equilibrium interfacial structures.

description: This article is a multi-voiced report on an innovative method of teaching an introductory course on Amazonian ethnology at the Institute of Social and Cultural Anthropology of the Ludwig-Maximilians-Universität in Munich. This course foregrounds the voices of indigenous colleagues of the postgraduate program of social anthropology (PPGAS) of the Federal University of Amazonas (UFAM). Indigenous interlocutors open up (via videoconference) a panorama of contemporary lifeworlds in Amazonia and reflect on it with their different approach of an Antropologia Indígena. This seminar amounts to a modest, albeit effective decolonizing method of teaching anthropology.

description: We study the spectrum of quasinormal mode frequencies for a Proca field on a rotating black hole spacetime. First, we review how the introduction of field mass modifies the spectrum in the scalar-field case, leading to evanescent modes and to quasiresonance. Next, we examine the three physical polarizations of the Proca field and their relation to the electromagnetic field modes in the massless limit. Exploiting a separation of variables, we obtain a five-term recurrence relation from an appropriate ansatz for the radial function. Gaussian elimination and the modified Lentz algorithm are applied, and the quasinormal frequencies are computed from the roots of a continued fraction. We validate our method by calculating quasibound state frequencies, which are complementary to quasinormal modes, and which can be calculated using the same method. We present a selection of results for the low-lying overtones of all three polarizations, across a range of black hole spins and field masses.

description: GRB 040422 was detected by the INTEGRAL satellite at an angle of only 3 degrees from the Galactic plane. Analysis of the prompt emission observed with the SPI and IBIS instruments on INTEGRAL are presented. The IBIS spectrum is well fit by the Band model with a break energy of Eo=56+/-2 keV and Epeak=41+/-3 keV. The peak flux is 1.8 10^(-7) erg/cm2/s and fluence 3.4 10^(-7) erg/cm2 in the range 20-200 keV. We then present the observations of the afterglow of GRB 040422, obtained with the ISAAC and FORS 2 instruments at the VLT less than 2 hours after the burst. We report the discovery of its near-infrared afterglow, for which we give here the astrometry and photometry. No detection could have been obtained in the R and I bands, partly due to the large extinction in the Milky Way. We re-imaged the position of the afterglow two months later in the Ks band, and detected a likely bright host galaxy. We compare the magnitude of the afterglow with a those of a compilation of promptly observed counterparts of previous GRBs, and show that the afterglow of GRB 040422 lies at the very faint end of the distribution, brighter only than that of GRB 021211, singled out later and in the optical bands, and GRB 040924 after accounting for Milky Way extinction. This observation suggests that the proportion of dark GRBs can be significantly lowered by a more systematic use of 8-m class telescopes in the infrared in the very early hours after the burst.

Strategic Narcissism: A Lived Experience of ‘Decolonising’, Inclusion of and ‘Collaborations’ with Indigenous Researchers
Creators: name: Abd El Gawad, Heba
Publisher: name: Zeitschrift für Ethnologie/Journal of Social and Cultural Anthropology
Year: 2024

description: Based on my lived experience, the current decolonizing turn towards increasing the inclusion of and collaborations with indigenous researchers is characterized by strategic narcissism. Collaborations are shaped by wishful thinking, ignoring our lived experience and realities on the ground. While decolonizing is framed by Global North academic institutions as a moral project, it could be seen as empty, exploitative and extractive by indigenous researchers. In this short commentary, I reflect on recent ‘decolonial’ attempts to reform the practices and policies of inclusions of and collaborations with indigenous researchers based on my lived experience as an indigenous Egyptian heritage and museums researcher. I argue that the current promotion of Eurocentric perceptions of equity and ethics as universal is rooted in strategic narcissism. It serves the Global North in clearing its consciousness while forcing indigenous researchers into colonial assimilation and violence. I call for a shift towards empathy as an indigenous-centred approach to dismantling current recolonizing decolonial framing honouring the emotional tax and lived experience of indigenous researchers. Global North institutions and researchers are invited to self-reflect and question for whom are they doing this decolonizing work?

description: Museums often prioritize connecting with their audiences, but they may neglect the importance of providing internal spaces for staff to communicate openly. This article thinks through the first Prep Room project at the GRASSI Museum für Völkerkunde in Leipzig, Staatliche Kunstsammlungen Dresden, whose invited residents were brought together in a process of dialogical curating museums staff. The goal was to transcend classic notions of curating by focusing on the processual aspects of co-creating multilayered transdisciplinary methodologies to foster an informal space for reflection and exchange. During these in-depth discussions, the participants explored the practical implications of having diverse ontologies in their collections and had an opportunity to reflect on their everyday practices.

description: In patients with atrial fibrillation, local activation time (LAT) maps are routinely used for characterising patient pathophysiology. The gradient of LAT maps can be used to calculate conduction velocity (CV), which directly relates to material conductivity and may provide an important measure of atrial substrate properties. Including uncertainty in CV calculations would help with interpreting the reliability of these measurements. Here, we build upon a recent insight into reduced-rank Gaussian processes (GP) to perform probabilistic interpolation of uncertain LAT directly on human atrial manifolds. Our Gaussian Process Manifold Interpolation (GPMI) method accounts for the topology of the atria, and allows for calculation of statistics for predicted CV. We demonstrate our method on two clinical cases, and perform validation against a simulated ground truth. CV uncertainty depends on data density, wave propagation direction, and CV magnitude. GPMI is suitable for probabilistic interpolation of other uncertain quantities on non-Euclidean manifolds.

description: We have carried out extensive radio and optical follow-up of 176 sources from the 15 GHz 9th Cambridge survey. Optical identifications have been found for 155 of the radio sources; optical images are given with radio maps overlaid. The continuum radio spectrum of each source spanning the frequency range 1.4 - 43 GHz is also given. Two flux-limited samples are defined, one containing 124 sources complete to 25 mJy and one of 70 sources complete to 60 mJy. Between one fifth and one quarter of sources from these flux-limited samples display convex radio spectra, rising between 1.4 and 4.8 GHz. These rising-spectrum sources make up a much larger fraction of the radio source population at this high selection frequency than in lower frequency surveys. We find that by using non-simultaneous survey flux density measurements at 1.4 and 15 GHz to remove steep spectrum objects, the efficiency of selecting objects with spectra rising between 1.4 and 4.8 GHz (as seen in simultaneous measurements) can be raised to 49 percent without compromising the completeness of the rising spectrum sample.

description: This paper examines the relationship between rurality and poverty, and the role the agricultural sector can play in rural development, poverty reduction, and overall development. The historical views regarding the role of the primary sector in development are presented, and then using original data, the paper argues that there was an historical misjudgment against the primary sector that served as a foundation for anti-agricultural bias in public policy until the late 80’s. Finally, this paper explains how under certain conditions territorial/regional development strategies may prosper, but in other conditions, particularly in the least-developed countries rural space, agriculture is still necessarily the starting point for rural development.

For the six currently known transiting planets, the data are consistent with a decreasing linear relation. The other known short-period planets, discovered through radial-velocity techniques, seem to agree with this relation. We briefly speculate about a tentative physical model to explain such a dependence.

description: Collaboration with creator communities has become a new paradigm for ethnological museums. In this article, we discuss the possibilities and limits of cooperation with stakeholders from creator communities based on our experience of the last five years, during which we created an exhibition together with the Nebraska Indian Community College (NICC) for the Humboldt Forum in Berlin. In 1894, the Königliches Museum für Völkerkunde commissioned Francis La Flesche, who is today considered the first Indigenous ethnologist, to assemble a collection of his own culture, the Umoⁿhoⁿ. ‘We don’t want another white guy to tell our story!’, Wynema Morris, Professor at the NICC, made clear when we told her about our plans to do an exhibition together with the college. The historical collection became the starting point for a collaborative project that was developed from 2017 to 2022. The experiences of racism, violence and loss of land still influence the living conditions of the Umoⁿhoⁿ community today. In this context, the Berlin collection is of particular importance, because it bears witness to the resistance against colonization. It offers the Umoⁿhoⁿ the opportunity to reconnect with their ancestors and present their own history to a German public. The project also made clear how deeply inscribed colonial contexts are in the collections of ethnological museums.

description: The paper reviews the implications for rural development of current transformations in agriculture. It first identifies some of the driving forces - in addition to the impact of rising incomes in some but not all developing countries - behind the transformation process: changing market chains, shifts in public policy, OECD agricultural policies and HIV/AIDS. It then discusses some strategic issues for assisting the rural sector and small farms in developing countries: increasing the productivity of food staples, diversification into higher value products, organizing small farmer for marketing, agricultural services, non-farm opportunities and migration and targeting the vulnerable. It emphasizes the need for integrated interventions if small farm development is to offer a viable pro-poor option for agricultural development.

description: We investigate the liquid-glass phase transition in a system of point-like particles interacting via a finite-range attractive potential in D-dimensional space. The phase transition is driven by an `entropy crisis' where the available phase space volume collapses dramatically at the transition. We describe the general strategy underlying the first-principles replica calculation for this type of transition; its application to our model system then allows for an analytic description of the liquid-glass phase transition within a mean-field approximation, provided the parameters are chosen suitably. We find a transition exhibiting all the features associated with an `entropy crisis', including the characteristic finite jump of the order parameter at the transition while the free energy and its first derivative remain continuous.

description: Flare ribbons are bright manifestations of flare energy dissipation in the lower solar atmosphere. For the first time, we report on high-resolution imaging spectroscopy observations of flare ribbons situated off-limb in the H$β$ and Ca II 8542 Å lines and make a detailed comparison with radiative hydrodynamic simulations. Observations of the X8.2-class solar flare SOL2017-09-10T16:06 UT obtained with the Swedish Solar Telescope reveal bright horizontal emission layers in H$β$ line wing images located near the footpoints of the flare loops. The apparent separation between the ribbon observed in the H$β$ wing and the nominal photospheric limb is about 300 - 500 km. The Ca II 8542 Å line wing images show much fainter ribbon emissions located right on the edge of the limb, without clear separation from the limb. RADYN models are used to investigate synthetic spectral line profiles for the flaring atmosphere, and good agreement is found with the observations. The simulations show that, towards the limb, where the line of sight is substantially oblique with respect to the vertical direction, the flaring atmosphere model reproduces the high contrast of the off-limb H$β$ ribbons and their significant elevation above the photosphere. The ribbons in the Ca II 8542 Å line wing images are located deeper in the lower solar atmosphere with a lower contrast. A comparison of the height deposition of electron beam energy and the intensity contribution function shows that the H$β$ line wing intensities can be an useful tracer of flare energy deposition in the lower solar atmosphere

A Donkey for the White Visitor: Practices of Collecting (with) Forced Migrants

Year: 2024

description: At a time when public and political opinion towards forced migration is negatively inclined, many museums in Europe are applying a collaborative approach to address the stories of forced migrants (Boersma 2023; Sergi 2021). Through participatory projects, museum practitioners are attempting to put forward an alternative to the ‘authorized heritage discourse’ (Smith 2006), yet their practices rarely accommodate a shift towards a more inclusive discourse. Aiming to shed light on the experienced limitations of collaborative curation, this paper scrutinizes what lies in the wake of a participatory project. Assuming a focus on collection practices as a result of participatory work, this paper looks at one project in particular: ‘daHEIM: Glances into Fugitive Lives’, which was organized at the Museum Europäischer Kulturen in Berlin. Through interviews with former participants and museum practitioners, combined with one of the author’s lived experience of the project and its aftermaths, this paper unpacks the persistence of hierarchies within collaborative practices and the ways in which these feed into the discourse that is developed as a result. The paper starts from the process of collecting the potential outcomes of a participatory project within an inherently white institution, and it draws parallels between practices of care for people, as well as for their objects and artworks.

description: This paper explores a territorial approach to rural development in Latin America. It first reviews evidence that progress in rural social development has not been accompanied by reductions in income poverty and inequality. It then assesses qualitative changes that have occurred in rural incomes and the emergence of new opportunities for rural poverty reduction and draws implications for the potential of a territorial approach to rural development. Recent experiences with territorial approaches are briefly reviewed and lessons extracted for the implementation of such an approach. It concludes with a series of recommendations for implementation of a territorial approach to rural development.
Feedback Heating with Slow Jets in Cooling Flow Clusters

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a scenario in which a large fraction, or even most, of the gas cooling to low temperatures of T<10^4 K in cooling flow clusters, directly gains energy from the central black hole. Most of the cool gas is accelerated to non-relativistic high velocities, v ~ 10^3-10^4 km/sec, after flowing through, or close to, an accretion disk around the central black hole. A poorly collimated wind (or double not-well collimated opposite jets) is formed. According to the proposed scenario, this gas inflates some of the X-ray deficient bubbles, such that the average gas temperature inside these bubbles (cavities) in cooling flow clusters is kT_b ~< 100 keV. A large fraction of these bubbles will be very faint, or not detectable, in the radio. The bright rims of these weak smaller bubbles will appear as ripples. We suggest that the X-ray ripples observed in the Perseus cluster, for example, are not sound waves, but rather the rims of radio-faint weak bubbles which are only slightly hotter than their environment. This scenario is incorporated into the moderate cooling flow model; although not a necessary ingredient in that model, it brings it to better agreement with observations. In the moderate cooling flow model a cooling flow does exist, but the mass cooling rate is ~<10% of that in old versions of cooling flow models.

Rewarding Citizen Participation in Exhibitions: A Questionnaire Surveying Museum Practices

Year: 2024

description: The paper presents the results of a quantitative and qualitative study undertaken by a team of museum professionals and researchers based at the Museum of Civilizations of Europe and the Mediterranean (Mucem) in Marseilles, France, in 2020. The survey aimed to investigate the contemporary curation practices of European museums by asking in what ways collaboration enters into their scientific projects, curation and remuneration practices. The analysis draws on the survey responses of 118 French and international participants in their capacities as independent curators, representatives and professionals from European museums and patrimonial associations. In addition, two semi-structured interviews gave further insights into specific examples of collaborative or co-creative exhibitions, designed with vulnerable communities, that break with the norm of habitual power structures and dominant heritage production. The results indicate that, while the notion of ‘participation’ entails ambiguous categorizations ranging from academic to institutional to community actors, remuneration remains a desideratum, thus highlighting issues of acknowledgment, durability and, ultimately, the social legitimacy and justice of museal practices.

description: We report the optical detection of magnons with a broad range of wavevectors in magnetic insulator Y3Fe5O12 thin films by proximate nitrogen-vacancy (NV) single-spin sensors. Through multi-magnon scattering processes, the excited magnons generate fluctuating magnetic fields at the NV electron spin resonance frequencies, which accelerate the relaxation of NV spins. By measuring the variation of the emitted spin-dependent photoluminescence of the NV centers, magnons with variable wavevectors up to ~ 5 x 10^7 m-1 can be optically accessed, providing an alternative perspective to reveal the underlying spin behaviors in magnetic systems. Our results highlight the significant opportunities offered by NV single-spin quantum sensors in exploring nanoscale spin dynamics of emergent spintronic materials.

description: The paper discusses the economic effects of misallocation of public expenditures in favor of private goods rather than public goods. It first lays out certain key hypotheses regarding the consequences of the apparent public sector allocation inefficiency and the factors that explain this phenomenon. It then discusses existing empirical evidence that lends at least indirect support to these hypotheses. Finally, it presents new empirical evidence for the rural sector in Latin America which documents the extent of the misallocation of public expenditures, its consequences for agricultural growth and rural poverty, and the role of certain key politico-institutional factors in explaining the misallocation.

description: We consider the distribution of the non-Gaussian signal induced by weak lensing on the primary total intensity cosmic microwave background (CMB) anisotropies. Our study focuses on the three point statistics exploiting an harmonic analysis based on the CMB bispectrum. By considering the three multipoles as independent variables, we reveal a complex structure of peaks and valleys determined by the re-projection of the primordial acoustic oscillations through the lensing mechanism. We study the dependence of this system on the expansion rate at the epoch in which the weak lensing power injection is relevant, probing the dark energy equation of state at redshift corresponding to the equivalence with matter or higher ($w_\infty$). We evaluate the impact of the bispectrum observable on the CMB capability of constraining the dark energy dynamics. We perform a maximum likelihood analysis by varying the dark energy abundance, the present equation of state $w_0$ and $w_\infty$. We show that the projection degeneracy affecting a pure power spectrum analysis in total intensity is broken if the bispectrum is taken into account. For a Planck-like experiment, assuming nominal performance, no foregrounds or systematics, and fixing all the parameters except $w_0$, $w_\infty$ and the dark energy abundance, a percent and ten percent precision measure of $w_0$ and $w_\infty$ is achievable from CMB data only. These results indicate that the detection of the weak lensing signal by the forthcoming CMB probes may be relevant to gain insight into the dark energy dynamics at the onset of cosmic acceleration.

Analytic post-Newtonian expansion of the energy and angular momentum radiated to infinity by eccentric-orbit non-spinning extreme-mass-ratio inspirals to 19PN

description: We develop new high-order results for the post-Newtonian (PN) expansions of the energy and angular momentum fluxes at infinity for eccentric-orbit extreme-mass-ratio inspirals (EMRIs) on a Schwarzschild background. The series are derived through direct expansion of the MST solutions within the RWZ formalism for first-order black hole perturbation theory (BHPT). By utilizing factorization and a few computational simplifications, we are able to compute the fluxes to 19PN, with each PN term calculated as a power series in (Darwin) eccentricity to $e^{10}$. This compares favorably with the numeric fitting approach used in previous work. We also compute PN terms to $e^{20}$ through 10PN. Then, we analyze the convergence properties of the composite energy flux expansion by checking against numeric data for several orbits, both for the full flux and also for the individual 220 mode, with various resummation schemes tried for each. The match between the high-order series and numerical calculations is generally strong, maintaining relative error better than $10^{-5}$ except when $p$ (the semi-latus rectum) is small and $e$ is large. However, the full-flux expansion demonstrates superior fidelity (particularly at high $e$), as it is able to incorporate additional information from PN theory. For the orbit $(p=10, e=1/2)$, the full flux achieves a best error near $10^{-5}$, while the 220 mode exhibits error worse than $1\%$. Finally, we describe a procedure for transforming these expansions to the harmonic gauge of PN theory by analyzing Schwarzschild geodesic motion in harmonic coordinates. This will facilitate future comparisons between BHPT and PN theory.

Year: 2024

description: In the last three decades, museums and museological practices that are fundamentally based on Western knowledge systems have been strongly questioned by a collective that includes Indigenous Peoples, political activists, representatives of civil society and scholars. In the historiographic reconstructions promoted by the academy, one of the touchstones is the so-called ‘new’ museology of the mid- 1980s (Vergo 1989).

The CMS Precision Proton Spectrometer timing system: performance in Run 2, future upgrades and sensor radiation hardness studies
Creators: name: Bossini, Edoardo
Publisher: name: arXiv
Year: 2020
Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: Central exclusive processes can be studied in CMS by combining the information of the central detector with the Precision Proton Spectrometer (PPS). PPS detectors, placed symmetrically at more than 200 m from the interaction point, can detect the scattered protons that survive the interaction. PPS has taken data at high luminosity while fully integrated in the CMS experiment. The total amount of collected data corresponds to more than 100 fb$^{-1}$ during the LHC Run 2. PPS consists of 3D silicon tracking stations as well as timing detectors that measure both the position and direction of protons and their time-of-flight with high precision. The detectors are hosted in special movable vacuum chambers, the Roman Pots, which are placed in the primary vacuum of the LHC beam pipe. The sensors reach a distance of few mm from the beam. Detectors have to operate in vacuum and must be able to sustain highly non-uniform irradiation: sensors used in Run 2 have accumulated an integrated dose with a local peak of $\sim 5 \cdot 10^{15}$ protons/cm$^2$. The timing system is made with high purity scCVD diamond sensors. A new architecture with two diamond crystals read out in parallel by the same electronic channel has been used to enhance the detector performance. In this paper, after a general overview of the PPS detector, we describe the timing system in detail. The sensor and the dedicated amplification chain are described, together with the signal digitization technique. Performance of the detector in Run 2 is reported. Recently the sensors used in Run 2 have been tested for efficiency and timing performance in a dedicated test beam at DESY. Preliminary results on radiation damage are reported. Important upgrades of the timing system are ongoing for the LHC Run 3, with the goal of reaching an ultimate timing resolution better than 30 ps; they are also discussed here.

description: In this paper, we show that a system of localized particles, satisfying the Fermi statistics and subject to finite-range interactions, can be exactly solved in any dimension. In fact, in this case it is always possible to find a finite closed set of eigenoperators of the Hamiltonian. Then, the hierarchy of the equations of motion for the Green's functions eventually closes and exact expressions for them are obtained in terms of a finite number of parameters. For example, the method is applied to the two-state model (equivalent to the spin-1/2 Ising model) and to the three-state model (equivalent to the extended Hubbard model in the ionic limit or to the spin-1 Ising model). The models are exactly solved for any dimension d of the lattice. The parameters are self-consistently determined in the case of d=1.

description: We developed a radio interferometric technique for the observation of extensive air showers initiated by cosmic particles. In this proof-of-principle study we show that properties of extensive air showers can be derived with high accuracy in a straightforward manner. When time synchronisation below $\sim$1 ns between different receivers can be achieved, direction reconstruction resolution of $< 0.2^\circ$ and resolution on the depth of shower maximum of $<10$ g/cm$^2$ are obtained over the full parameter range studied, with even higher accuracy for inclined incoming directions. In addition, by applying the developed method to dense arrays of radio antennas, the energy threshold for the radio detection of extensive air showers can be significantly lowered. The proposed method can be incorporated in operational and future cosmic particle observatories and with its high accuracy it has the potential to play a crucial role in unravelling the composition of the ultra-high-energy cosmic-particle flux.
