description: The demixing transition of a binary fluid mixture of additive hard spheres is analyzed for different size asymmetries by starting from the exact low-density expansion of the pressure. Already within the second virial approximation the fluid separates into two phases of different composition with a lower consolute critical point. By successively incorporating the third, fourth, and fifth virial coefficients, the critical consolute point moves to higher values of the pressure and to lower values of the partial number fraction of the large spheres. When the exact low-density expansion of the pressure is rescaled to higher densities as in the Percus-Yevick theory, by adding more exact virial coefficients a different qualitative movement of the critical consolute point in the phase diagram is found. It is argued that the Percus-Yevick factor appearing in many empirical equations of state for the mixture has a deep influence on the location of the critical consolute point, so that the resulting phase diagram for a prescribed equation has to be taken with caution.

description: We explore the entanglement evolution of boundary intervals in eternal Janus black holes that can be embedded consistently into string theory in the low-energy limit. By studying the geodesics we show that there is a transition in the entanglement characteristic around the Page time, which manifests the unitarity of the evolution. We reproduce and reinterpret these bulk results from two different lower-dimensional perspectives: first as an interface CFT in the usual AdS/CFT correspondence and second as an effective gravity theory in one lower dimension coupled to a radiation background. In the limit where the number of interface degrees of freedom becomes large, we obtain an effective theory on appropriate branes that replace the deep interior region in the bulk, coined the shadow region. In this effective theory, we also identify the island of the radiation entanglement wedge and verify the newly proposed quantum extremization method. Our model clarifies that double holography with gravity in two higher dimensions can be realized in a concrete and consistent way and that the occurrence of islands is natural in one higher dimension. Furthermore, our model reveals that there can be a transitional behavior of the Page curve before the Page time, which is related to the emergence of new matter degrees of freedom on the branes.

description: Outcome mapping is a methodology for planning, monitoring and evaluating development initiatives that aim to bring about social change. The process of outcome mapping helps a project team or program to be specific about the actors it targets, the changes it expects to see and the strategies it employs. Results are measured in terms of the changes in behaviour, actions or relationships that can be influenced by the team or program. The methodology is comprised of several tools, which can be adapted to different contexts. It enhances team and program understanding of change processes, improves the efficiency of achieving results and promotes realistic and accountable reporting.
Enhancing dipolar interactions between molecules using state-dependent optical tweezer traps

Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: We show how state-dependent optical potentials can be used to trap a pair of molecules in different internal states at a separation much smaller than the wavelength of the trapping light. This close spacing greatly enhances the dipole-dipole interaction and we show how it can be used to implement two-qubit gates between molecules that are 100 times faster than existing protocols and than rotational coherence times already demonstrated. We analyze complications due to hyperfine structure, tensor light shifts, photon scattering and collisional loss, and conclude that none is a barrier to implementing the scheme.
description: Fixed a problem with the gate protocol and added details of the transport procedure. Corrected a missing factor of -2 in the expression for $\alpha^{(0)}$ in equation (2), and a missing factor of 2 in equation (S18). Corresponding minor corrections were made to figures 2 and 3, and to the text accompanying those figures

description: Adsorption of para-hydrogen films on Alkali metals substrates at low temperature is studied theoretically by means of Path Integral Monte Carlo simulations. Realistic potentials are utilized to model the interaction between two para-hydrogen molecules, as well as between a para-hydrogenmolecule and the substrate, assumed smooth. Results show that adsorption of para-hydrogen on a Lithium substrate, the most attractive among the Alkali, occurs through completion of successive solid adlayers. Each layer has a two-dimensional density approximatley equal 0.070 inverse square Angstroms. A solid para-hydrogen monolayer displays a higher degree of confinement, in the direction perpendicular to the substrate, than a monolayer Helium film, and has a melting temperature of about 6.5 K. The other Alkali substrates are not attractive enough to be wetted by molecular hydrogen at low temperature. No evidence of a possible superfluid phase of para-hydrogen is seen in these systems.

description: Net farm income for all representative farms in 2018 is projected to be lower than in 2008. Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income. Commodity prices are expected to fall from current levels however the final level is unknown. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates after 2009. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit farms are expected to increase to about 0.50.

description: This history of St. Mary's Hall is an account of how St. Mary's was isolated and how it exacerbated, relieved, offset and reversed that isolation. Within this scenario, the St. Mary's residents led their lives and, beyond all else, their reminiscences reveal that they regard as precious these times in which they lived. The history aims, then, to capture their experiences while they were at St. Mary's Hall rather than to document their later achievements. The history is, as well, a chronicle of human success and struggle, and of human strength and limitedness. That is as it should be since these are the features of each human life.

description: Since the summer of 2007, U.S. food price has increased dramatically. Given public anxiety over fast-rising food prices in recent years, this paper attempts to analyze the effects of market factors ─ prices of energy and agricultural commodities and exchange rate ─ on U.S. food prices using a co-integration analysis. Results show that the agricultural commodity price and exchange rate play key roles in determining the short- and long-run movement of U.S. food prices. It is also found that in recent years, the energy price has been a significant factor affecting U.S. food prices in the long-run, but has little effect in the short-run. This implies the strong long-run linkage between energy and agricultural markets has emerged through production of commodity-based ethanol in the recent years.

Scholia Latina in Platonem. La recezione del Menone e del Fedone nel Medioevo latino
Creators: name: Bisanti, Elisa
Publisher: name: Università degli studi di Trento
Year: 2021

description: This study offers a reinterpretation of the direct tradition of medieval Platonism on the basis of new evidence from the Meno and the Phaedo translated into Latin by Henry Aristippus between 1154 and 1160. In particular, it provides an edition of interlinear and marginal annotations and glosses of the Meno and the Phaedo: the manuscript tradition is particularly useful for understanding which aspects of these two Platonic dialogues were particularly studied during the Middle Ages, as it preserves the considerations of various readers on Platonic philosophy. In the most fortunate cases, it is precisely the manuscript tradition that offers new perspectives that can be used to redesign the networks of reception of the two Platonic texts examined in this study in the centuries following their translation, with particular reference to the 13th and 14th centuries. The research was carried out on unpublished material and manuscript testimonies, with the help of two strategies. First, the medieval sources were submetted to a doxographic analysis, through a bottom-up approach consisting in the identification of the terms ‘Plato’, ‘Meno’, ‘Phaedo’ (or ‘Fedrone’ according to medieval usage). This allowed to understand in which contexts and in relation to which themes the references to the three terms appeared and to provide a list of authors who, between the 13th and the 14th century, had the opportunity to read the Meno and/or the Phaedo in Henry Aristippus’ translation. The second strategy, which we could perhaps describe as ‘inside-out’, was applied in the editing phase of the interlinear and marginal annotations and glosses of the two translations. As an especially important paratextual element, the ‘marginal’ writing proves to be particularly useful for deriving the constituent elements of the two dialogues (inside) that were commented, re-written, re-elaborated and interpreted in the margins of the two texts (outside). By employing both strategies, it is possible to reveal the core concepts of Platonic philosophy that, to a greater or lesser extent, caught the attention of medieval readers of the Latin Meno and the Phaedo.

Year: 2021

description: Class Act is a project implemented in Ukraine and addressed to young people. The idea behind it is to organize playwriting workshops for teenagers affected by the war in the eastern part of the country. This project makes use of the therapeutic potential of the theater, facing such problems as political prejudices, social stereotypes and children’s traumatic war experiences. Participants in workshop classes are enabled to understand the nature of the negative stimuli shaping their emotions. Moreover, they learn, e.g., the causes of social phenomena and their harmful effects, thus introducing a humanistic factor to their observations.

description: We demonstrate Mach-Zehnder-type interferometry in a superconducting flux qubit. The qubit is a tunable artificial atom, whose ground and excited states exhibit an avoided crossing. Strongly driving the qubit with harmonic excitation sweeps it through the avoided crossing two times per period. As the induced Landau-Zener transitions act as coherent beamsplitters, the accumulated phase between transitions, which varies with microwave amplitude, results in quantum interference fringes for n=1...20 photon transitions. The generalization of optical Mach-Zehnder interferometry, performed in qubit phase space, provides an alternative means to manipulate and characterize the qubit in the strongly-driven regime.

description: This paper uses WITCH, an integrated assessment model with a game-theoretic structure, to explore the prospects for, and the stability of broad coalitions to achieve ambitious climate change mitigation action. Only coalitions including all large emitting regions are found to be technically able to meet a concentration stabilisation target below 550 ppm CO2eq by 2100. Once the free-riding incentives of non-participants are taken into account, only a “grand coalition” including virtually all regions can be successful. This grand coalition is profitable as a whole, implying that all countries can gain from participation provided appropriate transfers are made across them. However, neither the grand coalition nor smaller but still environmentally significant coalitions appear to be stable. This is because the collective welfare surplus from cooperation is not found to be large enough for transfers to offset the free-riding incentives of all countries simultaneously. Some factors omitted from the analysis, which might improve coalition stability, include the co-benefits from mitigation action, the costless removal of fossil fuel subsidies, as well as alternative assumptions regarding countries’ bargaining behaviour.

Year: 2021

description: This article aims to contribute to the available data, presenting exemplary sources that may constitute point of reference for experts who seek information on sociological, anthropological and ethnological dimensions of the topic. It is crucial to highlight the evidence on some main aspects concerning Azerbaijan, on which there is a lack of precise information. Possibilities of a potential consolidation between Armenia and Azerbaijan are exposed indicating existing disadvantages of the process. Articles from the press, interviews of experts and expatriates of Armenian origin that lived in Azerbaijan; an interview with soldiers captured during the military operation versus Armenia is offered. Historical sources and contemporary official data presented. Despite critique and debates against an anthropological defense, this article brings forward information that might offer ideas on conflict solving perspectives within war studies. Article attempts to state paramount importance of growing awareness on the heavy exploitation of the ignorance of masses by some activists and press, concluded primarily through social media. Furthermore, article aims to oppose people's attitude of passively accepting facts without scrupulous investigation.

Subjects: subject: Institutional and Behavioral Economics
subject: Article 82EC

subject: Abuse

description: The Commission's Guidance paper on exclusionary abuse under Article 82 EC is open to three fundamental criticisms. First, it leads to less legal certainty, because the rules suggested are vague and imprecise, because dominant companies will not have the information needed to apply them, and because the Commission is trying to change the law, which it has no power to do. Second, it would lead to some anticompetitive effects, because in practice it discourages price competition, by discouraging individualised price negotiations and retroactive rebates, and by suggesting that the Commission will protect not-yet-as-efficient competitors from price competition. Third, it leads to too many "false positives", i.e., findings of exclusionary abuse that are not justified in economics or law. The solution is to return to the test in the Treaty as interpreted by the Court of Justice: an exclusionary abuse must involve limiting the production, marketing or technical development of competitors of the dominant company, if harm is caused to consumers.

description: This article presents the research problems addressed in military anthropology. The central research hypothesis is a theoretical-cognitive problem concerning the object of cognition of military anthropology. In this sense, the two main understandings of military anthropology, American and Russian, are shown. Military anthropology develops an interest in culture as an area of struggle, competition and combat. The article consists of three parts. The first part explains theoretical issues and the historical development of military anthropology. The second part presents the Russian tradition in the development of that discipline. The third part presents the Polish tradition in which military anthropology is an auxiliary science of security sciences.

description: This paper shows that, counter-intuitively, a higher elasticity of substitution in model production function can lead to reduced economic resilience and larger vulnerability to shocks in production factor prices. This result is due to the fact that assuming a higher elasticity of substitution requires a recalibration of the production function parameters to keep the model initial state unchanged. This result has consequences for economic analysis, e.g., on the economic vulnerability to climate change.

description: The aim of the paper is to suggest moving away from the dichotomy of ‘Anthropology of’ and ‘Anthropology for’ the military. In order to preserve the scientific character and the original anthropological perspective, the paper analyzes the theoretical impasse in which this sub discipline of Anthropology is pushed in the past decades due to the moralizing stance of research attitudes. In purely a theoretical manner, the paper dissects the main currents of research and ponders how the discipline boiled down on a scholarly debate which turns around ‘for’ v.s ‘of’ while being blissfully unware of illogical trapes it succumbs.

Cultural Projects as a Tool of Anthropological Defense. Ukrainian Example
Creators: name: Korzeniowska-Bihun, Anna
Publisher: name: Wiedza Obronna
Year: 2021

description: The article presents anthropological defense’s practical dimension on cultural activities observed during the Russian-Ukrainian war. The paper's primary hypothesis is to deliver anthropological defense strategic objectives from the perspective of a country at war. The adopted view refers to hybrid warfare and hybrid threats. The goals are as follows: 1) documentation objective, 2) therapeutic objective, 3) ideological objective, 4) diplomatic objective. A structured, consistent defense line allows creating a shared narrative by dividing society as the Ukrainian one. All actions in terms of anthropological defense refer to the values shared by the majority of citizens. Nevertheless anthropological defense tools' choice and use must be strategically conditioned, i.e., other benefits for cinematography, theatre, and fine arts. For an action to be practical cooperation between self-governing assemblages (as volunteers, artists, art curators) and state-actors must be established. The cooperation activities undertaken are complementary and complementary and can, therefore be remarkably efficient.

description: Antagonistic salts are salts which consist of hydrophilic and hydrophobic ions. In a binary mixture of water and organic solvent, these ions preferentially dissolve into different phases. We investigate the effect of an antagonistic salt, tetraphenylphosphonium chloride PPh$_4$Cl, in a mixture of water and 2,6-lutidine by means of Molecular Dynamics (MD) Simulations. For increasing concentrations of the salt the two-phase region is shrunk and the interfacial tension in reduced, in contrast to what happens when a normal salt is added to such a mixture. The MD simulations allow us to investigate in detail the mechanism behind the reduction of the surface tension. We obtain the ion and composition distributions around the interface and determine the hydrogen bonds in the system and conclude that the addition of salt alter the hydrogen bonding.

description: Agricultural sectors play a key role in the economics of climate change. Land as an input to agricultural production is one of the most important links between economy and the biosphere, representing a direct projection of human action on the natural environment. Agricultural management practices and cropping patterns have a vast effect on biogeochemical cycles, freshwater availability and soil quality. Agriculture also plays an important role in emitting and storing greenhouse gases. Thus, to consistently investigate climate policy and future pathways for the economic and natural environment, a realistic representation of agricultural land-use is essential. Computable General Equilibrium (CGE) models have increasingly been used to this purpose. CGE models simulate the simultaneous equilibrium in a set of interdependent markets, and are especially suited to analyze agricultural markets from a global perspective. However, modelling agricultural sectors in CGE models is not a trivial task, mainly because of differences in temporal and geographical aggregation scales. The aim of this study is to overview some proposed modelling strategies, by reviewing the available literature and highlighting the different trade-offs involved in the various approaches.

description: Large-scale network embedding is to learn a latent representation for each node in an unsupervised manner, which captures inherent properties and structural information of the underlying graph. In this field, many popular approaches are influenced by the skip-gram model from natural language processing. Most of them use a contrastive objective to train an encoder which forces the embeddings of similar pairs to be close and embeddings of negative samples to be far. A key of success to such contrastive learning methods is how to draw positive and negative samples. While negative samples that are generated by straightforward random sampling are often satisfying, methods for drawing positive examples remains a hot topic. In this paper, we propose SCE for unsupervised network embedding only using negative samples for training. Our method is based on a new contrastive objective inspired by the well-known sparsest cut problem. To solve the underlying optimization problem, we introduce a Laplacian smoothing trick, which uses graph convolutional operators as low-pass filters for smoothing node representations. The resulting model consists of a GCN-type structure as the encoder and a simple loss function. Notably, our model does not use positive samples but only negative samples for training, which not only makes the implementation and tuning much easier, but also reduces the training time significantly. Finally, extensive experimental studies on real world data sets are conducted. The results clearly demonstrate the advantages of our new model in both accuracy and scalability compared to strong baselines such as GraphSAGE, G2G and DGI.

description: The human thalamus relays sensory signals to the cortex and facilitates brain-wide communication. The thalamus is also more directly involved in sensorimotor and various cognitive functions but a full characterization of its functional repertoire, particularly in regard to its internal anatomical structure, is still outstanding. As a putative hub in the human connectome, the thalamus might reveal its functional profile only in conjunction with interconnected brain areas. We therefore developed a novel systems-level Bayesian reverse inference decoding that complements the traditional neuroinformatics approach towards a network account of thalamic function. The systems-level decoding considers the functional repertoire (i.e., the terms associated with a brain region) of all regions showing co-activations with a predefined seed region in a brain-wide fashion. Here, we used task-constrained meta-analytic connectivity-based parcellation (MACM-CBP) to identify thalamic subregions as seed regions and applied the systems-level decoding to these subregions in conjunction with functionally connected cortical regions. Our results confirm thalamic structure–function relationships known from animal and clinical studies and revealed further associations with language, memory, and locomotion that have not been detailed in the cognitive neuroscience literature before. The systems-level decoding further uncovered large systems engaged in autobiographical memory and nociception. We propose this novel decoding approach as a useful tool to detect previously unknown structure–function relationships at the brain network level, and to build viable starting points for future studies.
Splitting of Surface Plasmon Frequencies of Metal Particles in a Nematic Liquid Crystal

description: We calculate the effective dielectric function for a suspension of small metallic particles immersed in a nematic liquid crystal (NLC) host. For a random suspension of such particles in the dilute limit, we calculate the effective dielectric tensor exactly and show that the surface plasmon (SP)resonance of such particles splits into two resonances, polarized parallel and perpendicular to the NLC director. At higher concentrations, we calculate this splitting using a generalized Maxwell-Garnett approximation, which can also be applied to a small metal particle coated with NLC. To confirm the accuracy of the MGA for NLC-coated spheres, we also use the Discrete Dipole Approximation. The calculated splitting is comparable to that observed in recent experiments on NLC-coated small metal particles

description: This paper puts forward a model of the role of phosphorus in crop production, soil phosphorus dynamics and phosphorus loading that integrates the salient economic and ecological features of agricultural phosphorus management. The model accounts for the links between phosphorus fertilization, crop yield, accumulation of soil phosphorus reserves, and phosphorus loading. It can be used to guide precision phosphorus management and erosion control as means to mitigate agricultural loading. Using a parameterization for cereal production in southern Finland, the model is solved numerically to analyze the intertemporally optimal combination of fertilization and erosion control and the associated soil phosphorus development. The optimal fertilizer application rate changes markedly over time in response to changes in the soil phosphorus level. When, for instance, soil phosphorus is initially above the socially optimal steady state level, annually matching phosphorus application to the prevailing soil phosphorus stock produces significantly higher social welfare than using a fixed fertilizer application rate. Erosion control was found to increase welfare only on land that is highly susceptible to erosion.

description: When watching videos, the occurrence of a visual event is often accompanied by an audio event, e.g., the voice of lip motion, the music of playing instruments. There is an underlying correlation between audio and visual events, which can be utilized as free supervised information to train a neural network by solving the pretext task of audio-visual synchronization. In this paper, we propose a novel self-supervised framework with co-attention mechanism to learn generic cross-modal representations from unlabelled videos in the wild, and further benefit downstream tasks. Specifically, we explore three different co-attention modules to focus on discriminative visual regions correlated to the sounds and introduce the interactions between them. Experiments show that our model achieves state-of-the-art performance on the pretext task while having fewer parameters compared with existing methods. To further evaluate the generalizability and transferability of our approach, we apply the pre-trained model on two downstream tasks, i.e., sound source localization and action recognition. Extensive experiments demonstrate that our model provides competitive results with other self-supervised methods, and also indicate that our approach can tackle the challenging scenes which contain multiple sound sources.

subject: Gender studies

description: Purpose: The purpose of this study was to investigate how speech naturalness relates to masculinity–femininity and gender identification (accuracy and reaction time) for cisgender male and female speakers as well as transmasculine and transfeminine speakers.Method: Stimuli included spontaneous speech samples from 20 speakers who are transgender (10 transmasculine and 10 transfeminine) and 20 speakers who are cisgender (10 male and 10 female). Fifty-two listeners completed three tasks: a two-alternative forced-choice gender identification task, a speech naturalness rating task, and a masculinity/femininity rating task.Results: Transfeminine and transmasculine speakers were rated as significantly less natural sounding than cisgender speakers. Speakers rated as less natural took longer to identify and were identified less accurately in the gender identification task; furthermore, they were rated as less prototypically masculine/feminine.Conclusions: Perceptual speech naturalness for both transfeminine and transmasculine speakers is strongly associated with gender cues in spontaneous speech. Training to align a speaker’s voice with their gender identity may concurrently improve perceptual speech naturalness.
