description: Biofortification of crops to combat micronutrient deficiencies is gaining global recognition. Projects promoting biofortified crops use intensive agriculture-nutrition education and extension to increase adoption of such crops. This study used discrete choice regression analysis and data collected from households targeted by a project with one of the most intense agriculture-nutrition education and extension program to test the effect of such program on the adoption and diffusion of biofortfied crops. The study was conducted in western Kenya and involved 537 households with children under 5 years, a pregnant or lactating women. The study finds that intensive agriculture-nutrition education and extension programs adopted by some of the biofortification projects indeed increases the likelihood of adoption and diffusion of biofortified crops. It specifically finds that participation in events that offer practical education on the agronomy and preparation of foods from such crops, participation in mother-to-mother nutrition support platforms and nutrition-focused health talks affect adoption and diffusion of biofortified crops, but with varying degrees of importance. Among control factors, ability to conserve the planting material over dry period and household assets-endowments are important in both adoption and diffusion of biofortified crops. The paper discusses the implications of these findings. Acknowledgement : This research was undertaken as part of the CGIAR Research Program on Roots, Tubers and Bananas (RTB).

description: With the booming of e-commerce, consumers are turning to online markets for food. Among all countries, China has the largest food online buyers with 0.541 billion consumers shopping for food online. Thanks to the free services provided by multiple e-commerce and social platforms and to the developed delivery networks, farmers can sell their products online at low transition cost in China. Meanwhile, the capacities of online stores to highlight traceablity and production process and of platforms to reveal quality signals through consumer s reviewing and scoring systems, can decrease asymmetric information about food product quality and safety compared with offline markets. Thus, those special features of online market may in return to encourage farmers to change their marketing plans to sell more safe food online. Our paper uses choice experiment method to solicit farmers different production and marketing preferences, and finds that farmers perceive higher rewards selling safer products than conventional products when using e-commerce platforms, an evidence supporting the positive impact of online market channel on the supply of safer food.

description: A “silent minority” until the end of the 20th century, Arab and Muslim Americans became, literally overnight, a "problem" ethnic group in the US consensus after the terrorist attacks of 9/11, when on the one hand Islamophobia was adopted as the leading trope of national grievance, while on the other a massive surveillance apparatus was put in place in order to ostensibly address the risk of internal radicalization, resulting in visible loss of civil rights for Arab and Muslim minorities in the US. This paper explores the deployment of the US security state against America Arabs and Muslims after 9/11, and sets it within the complex history of Middle Eastern and South Asian immigration to the US in the 20th century.

description: A new quasigroup approach to conservation laws in general relativity is applied to study asymptotically flat at future null infinity spacetime. The infinite-parametric Newman-Unti group of asymptotic symmetries is reduced to the Poincaré quasigroup and the Noether charge associated with any element of the Poincaré quasialgebra is defined. The integral conserved quantities of energy-momentum and angular momentum are linear on generators of Poincaré quasigroup, free of the supertranslation ambiguity, posess the flux and identically equal to zero in Minkowski spacetime.

description: Retrieving videos of a particular person with face image as a query via hashing technique has many important applications. While face images are typically represented as vectors in Euclidean space, characterizing face videos with some robust set modeling techniques (e.g. covariance matrices as exploited in this study, which reside on Riemannian manifold), has recently shown appealing advantages. This hence results in a thorny heterogeneous spaces matching problem. Moreover, hashing with handcrafted features as done in many existing works is clearly inadequate to achieve desirable performance for this task. To address such problems, we present an end-to-end Deep Heterogeneous Hashing (DHH) method that integrates three stages including image feature learning, video modeling, and heterogeneous hashing in a single framework, to learn unified binary codes for both face images and videos. To tackle the key challenge of hashing on the manifold, a well-studied Riemannian kernel mapping is employed to project data (i.e. covariance matrices) into Euclidean space and thus enables to embed the two heterogeneous representations into a common Hamming space, where both intra-space discriminability and inter-space compatibility are considered. To perform network optimization, the gradient of the kernel mapping is innovatively derived via structured matrix backpropagation in a theoretically principled way. Experiments on three challenging datasets show that our method achieves quite competitive performance compared with existing hashing methods.

description: The interaction of light with subwavelength metallic nano-structures is at the heart of different current scientific hot topics, namely plasmonics, metamaterials and nanoantennas. Research in these disciplines during the last decade has given rise to new, powerful concepts providing an unprecedented degree of control over light manipulation at the nanoscale. However, only recently have these concepts been used to increase the capabilities of light processing in current photonic integrated circuits (PICs), which traditionally rely only on dielectric materials with element sizes larger than the light wavelength. Amongst the different PIC platforms, silicon photonics is expected to become mainstream, since manufacturing using well-established CMOS processes enables the mass production of low-cost PICs. In this review we discuss the benefits of introducing recent concepts arisen from the fields of metamaterials, plasmonics and nanoantennas into a silicon photonics integrated platform. We review existing works in this direction and discuss how this hybrid approach can lead to the improvement of current PICs enabling novel and disruptive applications in photonics.

description: Figure S6. Gene ontology analysis of mouse hiBiv and loBiv associated genes. Gorilla and REViGO tools were coupled to define and reduce redundancy for enriched gene ontology terms in murine hiBiv and loBiv compared to all genes. Colour coding of the scatterplots are related to the log10 of the enriched p-values estimated by Gorilla. Area of circular plotted data is proportional to the number of genes enriched in each GO term. Redundant GO terms are reduced using the method of ‘semantic similarity’ measurement which is analogous to hierarchical clustering methods. This involves generating clusters of similar GO terms based on close p-values and whether one term is a child node of the other term [76].

description: In this paper, we analyze the effects of the Russian agricultural import ban in 2014, i.e. sudden access of the Serbian pork traders to the Russian market, on price and margin developments along the Serbian pork value chains. We use a regime-switching long-run price transmission model to investigate possible changes in market integration between Serbian and Russian pork markets, and at the same time identify if their newly established trade relation affect already existing integration of the Serbian market with the EU. Furthermore, we use the price transmission model to assess the effects of surge in Serbian pork export on transmission of price changes along the pork value chains. Our results indicate a significant improvement of market integration between Serbia and Russia after 2014 characterized by 80% reduction in transaction costs and almost complete transmission of price changes from the Serbian market towards Russian pork market. Also, the results of the domestic price effects indicate complete transmission of price changes from processors towards retailers after 2014, which means that Serbian consumers bore the biggest burden of significant domestic pork price changes caused by the surge in pork exports.

Fractal Physis: Structural Decoherence and the Cosmological Basis  of Wavefunction Collapse
Creators: name: Westwood, Danny
Publisher: name: Zenodo
Year: 2025
Subjects: subject: Quantum physics
subject: Gravity
subject: Physics

description: We propose the first empirically grounded, structure-based model of quantum decoherence, derived from the fractal coherence properties of the Cosmic Microwave Background (CMB). Using wavelet energy scaling on Planck SMICA data, we extract a scale-dependent coherence decay function and map it to physical space via a logarithmic transformation. This function is integrated into a modified Schrödinger framework, introducing decoherence not via stochastic noise or environment tracing, but as a structural constraint.

Double-slit simulations under this constraint exhibit smooth, scale-sensitive interference collapse aligned with the CMB's multipole structure, revealing a natural decoherence threshold near ℓ ∼ 4000. These results suggest that the quantum-classical transition may arise not from observers or entanglement, but from a structural boundary condition inherent to the universe itself. This offers a testable, simulation-friendly alternative to interpretation-based decoherence models and suggests a new avenue for reconciling quantum mechanics with general relativity via cosmological structure.

Security and Surveillance: Los Angeles Police and Land Abuses in Thomas Pynchon’s Inherent Vice
Creators: name: Di Vilio, Antonio
Publisher: name:  JAm It! (Journal of American Studies in Italy)
Year: 2022

description: On the theoretical backdrop of Foucault’s studies about the space and Deleuze’s inquiry on the society of control, this article aims to question the meaning of civil rights and freedom in an ultra-monitored society, within Thomas Pynchon’s Inherent Vice. This novel, in fact, provides not only a precise historical account of Los Angeles in the late Sixties but also a reflection about police and government policies concerning the process of reorganization of the space in Los Angeles and the several public disorder episodes connected to these policies. In the form of a detective fiction, Pynchon continues the investigation on Los Angeles land abuse carried out by Mike Davis and Edward Soja’s essays (such as City of Quartz and Thirdspace) on the postmodern metropolis par excellence. In fact, land speculation, segregation, inequality and racial violence were just some of the rotted fruits that fell out of the ruthless government tree. Pynchon explores the relationship between federals and magnates, the urgency of making Los Angeles a theme-park paradise, the utopia city par excellence, the dreaming of prosperity and flourishing that created an atmosphere of terror and paranoia. On the other side, the counterculture, hippies, groups, communities and all those who had been segregated geographically or ideologically, tried to feed their ethnic and cultural identity against the flatland developers. Starting from this ideological battlefield, this article moves to analyze the nature of late capitalism logic consequences in the Los Angeles civil rights era, and how the countercultural utopia was doomed often in behalf of social injustice and racial restrictions.

Piecing Together African Americans’ Future: The Subversive Relationship Between Children and Death as a Space Of Cultural and Historical Reappropriation in Jesmyn Ward’s Sing, Unburied, Sing
Creators: name: Pesce, Elisa
Publisher: name:  JAm It! (Journal of American Studies in Italy)
Year: 2022

description: This paper explores representations in literature of the direct and indirect consequences of the U.S. state of policing on twenty-first-century African American children. Ever since Achille Mbembe’s first conceptualization of necropolitics as an ultimate expression of sovereignty in late-modern colonial contexts, the incessant development in the United States of more and more subtle ways to enforce necro citizenship on specific demographic groups have prompted scholars to further reflect on attitudes toward death in contemporary Western societies. In particular, the necessity emerged to restore necropolitics’ role as a universal process underlying the establishment of communities’ cultural and historical awareness through the practice of collective mourning. By analyzing children characters in Jesmyn Ward’s Sing, Unburied, Sing, I argue that if, on the one hand, children’s inherent ability to represent the future is marred among African Americans by ongoing racial discrimination and injustice, on the other hand, it can also become a powerful means to overturn oppressive necropolitical discourses and practices. While engaging in a long tradition of protest literature which uses African spirituality to create literary sites of resistance for Black Americans, Ward’s novel intersects Sharon P. Holland’s theory about the liberating, political power of creative writing on several levels, the most interesting and subversive of which is Kayla’s character. The three-year-old ‘crossblood’ toddler does not only embody the past and present history of African Americans, from the experience of the Middle Passage to a condition of forced silence; more significantly, she challenges received assumptions about childhood and the marginal(ized) position of her people in U.S. society by engaging with death and the dead, thus offering a redemptive and liberating perspective from which to conceive and (re)build African Americans’ future.

Vessels of Flesh And Bones: Policing and Ethical Grammars in Ta-Nehisi Coates’s Between The World And Me
Creators: name: Puyuelo Ureña, Eva
Publisher: name:  JAm It! (Journal of American Studies in Italy)
Year: 2022

description: The year when Ta-Nehisi Coates’s Between the World and Me (2015) was published has went down as the deadliest year for black youth at the hands of policemen, with no less than 1,134 murders recorded. As he states in many interviews, this is one of the reasons that led Coates to pen down his work —to publicly lament so many losses; to confront the difficulties to mourn such violent and untimely deaths; and to shed light on the murderous racist practices that black individuals deal with on a daily basis. To do so, Coates embarks on a journey through history in which he memorializes many black individuals who, until now, have lost their lives in racist violent attacks —from his friend Prince Jones and other several well-known individuals murdered in the last decades, such as Michael Brown or Sean Bell, to, as Toni Morrison puts it, “the disremembered and unaccounted for” (2010, 323). Far from only providing Coates and his son with crucial information about the sociality of blackness, witnessing the death of so many also instils in both a feeling of belonging. Coates’s attempt at developing communal bonds through his narration riffs on the concept of “bottomline blackness”, which Elizabeth Alexander coined amidst her analysis of the public responses to Rodney King’s beating, which she regards as an incident that ended up “consolidat[ing] group affiliations” (78) and forging a “traumatized collective historical memory” (79). Drawing on Ta-Nehisi Coates’s celebrated memoir, and bearing into consideration Coates’s telling his son that “there is no real distance between you and Trayvon Martin” (2015, 25), this paper engages in the ongoing discussion about whether literary representations of racist bigotries can foster empathic relations or, on the contrary, disavow easy identification from readers.

description: We present a new version of holographic cosmology, which is compatible with present observations. A primordial $p=ρ$ phase of the universe is followed by a brief matter dominated era and a brief period of inflation, whose termination heats the universe. The flatness and horizon problems are solved by the $p=ρ$ dynamics. The model is characterized by two parameters, which should be calculable in a more fundamental approach to the theory. For a large range in the phenomenologically allowed parameter space, the observed fluctuations in the cosmic microwave background were generated during the $p=ρ$ era, and are exactly scale invariant. The scale invariant spectrum cuts off sharply at both upper and lower ends, and this may have observational consequences. We argue that the amplitude of fluctuations is small but cannot yet calculate it precisely.

description: We report measurements on Ti$_4$MnBi$_2$, where a crystal structure involving linear chains of Mn ions suggests one-dimensional magnetic character. The electrical resistivity is metallic, consistent with the results of electronic structure calculations that find a robust Fermi surface albeit with moderate electronic correlations. Curie-Weiss fit to the magnetic susceptibility finds that the Mn moments are in the low-spin $S = 1/2$ configuration. Neutron diffraction measurements detect weak antiferromagnetic order within the Mn chains, with further evidence for the small staggered moment coming from the entropy associated with the ordering peak in the specific heat as well as from the results of spin-polarized electronic structure calculations. The antiferromagnetic moments are apparently associated with the $d_{x^{2}-y^{2}}$ and $d_{xy}$ orbitals of Mn while the remaining Mn orbitals are delocalized. Strong quantum fluctuations, possibly related to an electronic instability that forms the Mn moment or to the one-dimensional character of Ti$_4$MnBi$_2$, nearly overcome magnetic order.

description: We propose a novel structural model of quantum decoherence based on the fractal coherence properties of the Cosmic Microwave Background (CMB). Using wavelet energy scaling on Planck SMICA data, we extract a scale-dependent coherence function f(l) and map it to physical space f(z) via a logarithmic transformation. This empirical function is integrated into a modified Schr ̈odinger equation, introducing decoherence as a function of cosmological structure.

Simulations of double-slit propagation under this framework reveal coherent-to-incoherent transitions that align with real CMB-derived decoherence boundaries near l ∼ 4000. Our results suggest a cosmologically-grounded, scale-structured foundation for quantum-classical transition, offering a testable alternative to environment-based interpretations of wavefunction collapse.

New Traditional Pork Products (TPP) and Innovative Traditional Pork Products (ITPP) from six untapped pig breeds in Croatia (Turopolje), France (Gascon), Italy (CintaSenese), Slovenia (Kr kopolje) and Spain (Porc Negre Mallorqu ) were analysed. Consumers real purchase intention and acceptance were investigated with a specific attention on how consumers Food Neophobic attitude (FNS) may impact their preferences. An integrated experimental approach was applied using two Non-Hypothetical Discrete Choice Experiment (DCE) carried out before and after a sensory test. A mother Logit models with Random Parameters specification were estimated and the willingness to pay were derived. Preliminary results showed that food neophobic consumers are reluctant to purchase the TPP and the ITPP and exhibited lower expected and actual liking scores. When consumers are not familiar with the innovations type (meat with added dietary fiber and with natural antioxidant), the eating experience confirms expectations. However, when innovations are known, the eating experience affected preferences. In this case, marketing strategies that give consumers the occasion to taste the new products may help introducing them to new market.

description: Recent breakthroughs in representation learning of unseen classes and examples have been made in deep metric learning by training at the same time the image representations and a corresponding metric with deep networks. Recent contributions mostly address the training part (loss functions, sampling strategies, etc.), while a few works focus on improving the discriminative power of the image representation. In this paper, we propose DIABLO, a dictionary-based attention method for image embedding. DIABLO produces richer representations by aggregating only visually-related features together while being easier to train than other attention-based methods in deep metric learning. This is experimentally confirmed on four deep metric learning datasets (Cub-200-2011, Cars-196, Stanford Online Products, and In-Shop Clothes Retrieval) for which DIABLO shows state-of-the-art performances.

description: Figure S4. Quintile chromatin configuration at murine bivalent promoters. As an alternative to k-means clustering we divided the data underlying Fig. 2d into H3K27me3:H3K4me3 quintiles determined by the ChIPseq signal ratio. We found that this approach reproduces hiBiv (Q5). As with k-means clustering, the Q5 quintile is relatively enriched in PRC components (EZH2, RING1B and uH2A) and depleted of activating marks (H3K4me3 & H2AZ). Q4,Q3,Q2,Q1 account for the loBiv set of regions. KDM2B, which binds to the majority of CGI is relatively uniform across the five quintiles.

Dialogically Destabilizing Discourses of Power/Knowledge in Ralph Ellison’s Invisible Man
Creators: name: Baldwin, Zebulah
Publisher: name:  JAm It! (Journal of American Studies in Italy)
Year: 2022

description: This paper offers an analysis that is centered on the structural and rhetorical aspects of Ralph Ellison’s novel Invisible Man, arguing that attention to the “formal” aspects of the text―such as the ways that contested terms, ambivalent tropes, and ambiguous symbols function to disrupt readerly assumptions―allows for a radically different understanding of the novel, specifically in terms of its representation of how American society functions to produce and police structures of domination. This analysis reconsiders the representations of race and African American culture in terms of their imbrication in popular discourses and stereotypes, reconceives the novel’s representation of the protagonist’s journey as a counter to the conventional ideological determinations of the genre of the coming-of-age story, and argues for a fundament rethinking the critical consensus surrounding the protagonist’s ostensible quest for “visibility.” Through these arguments, this paper illustrates the major conceptual congruencies between Ellison’s novel and the discourse theory of Michel Foucault, and demonstrates the purchase of this analysis through examining two aspects of Ellison’s novel that have received very little scholarly attention to date: the conflict over the meaning of the term “brother” throughout the novel, and the paradoxical complexity of the network of cultural-historical materials that construct the identity of the African American couple whose belongings fill the snow-covered street in the “dispossession” scene.

description: Solar flares show remarkable variety of the energy partitioning between thermal and nonthermal components. Those with a prominent nonthermal component but only a modest thermal one are particularly well suited to study the direct effect of the nonthermal electrons on plasma heating. Here, we analyze such a well observed, impulsive single-spike nonthermal event, a SOL2013-11-05T035054 solar flare, where the plasma heating can be entirely attributed to the energy losses of these impulsively accelerated electrons. Evolution of the energy budget of thermal and nonthermal components during the flare is analysed using X-ray, microwave, and EUV observations and three-dimensional modeling. The results suggest that (i) the flare geometry is consistent with a two-loop morphology and the magnetic energy is likely released due to interaction between these two loops; (ii) the released magnetic energy converted to the nonthermal energy of accelerated electrons only, which is subsequently converted to the thermal energy of the plasma; (iii) the energy is partitioned in these two flaring loops in comparable amounts; (iv) one of these flaring loops remained relatively tenuous but rather hot, while the other remained relatively cool but denser than the first one. Therefore, this solar flare demonstrates an extreme efficiency of conversion of the free magnetic energy to the nonthermal energy of particle acceleration and the energy flow into two loops from the non-thermal to thermal one with a negligible direct heating.

description: A complementary Gray code for binary n-tuples is one that, when all the tuples are complemented, is identical to itself; this is equivalent to the complement of the first half of the code being identical to the second half. We generalize the notion of complementary to q-ary n-tuples, fixed size combinations of an n-set and permutations and, in each case, construct complementary Gray codes. We relax, as weakly as possible, the notions of complementary to cases where necessary conditions for existence are violated and construct Gray codes within the weakened definitions: these include binary n-tuples when n is odd and Lee metric q-ary n-tuples when n is odd and q is even. Finally a lemma used in the construction for permutations offers the first known cyclic Gray code for the permutations of a particular family of multisets.

description: (Abridged) We report results from a comprehensive study of the nearby M dwarf Proxima Centauri with the XMM-Newton satellite. We find strongly variable coronal X-ray emission, with flares ranging over a factor of 100 in peak flux. The low-level emission is found to be continuously variable. Several weak flares are characteristically preceded by an optical burst, compatible with predictions from standard solar flare models. We propose that the U band bursts are proxies for the elusive stellar non-thermal hard X-ray bursts suggested from solar observations. A very large X-ray flare was observed in its entirety, with a peak luminosity of 3.9E28 erg/s [0.15-10 keV] and a total X-ray energy of 1.5E32 erg. This flare has allowed to measure significant density variations from X-ray spectroscopy of the OVII He-like triplet; we find peak densities reaching up to 4E11 cm^-3 for plasma of about 1-5 MK. Abundance ratios show little variability in time, with a tendency of elements with a high first ionization potential to be overabundant relative to solar photospheric values. We do not find significant effects due to opacity during the flare, indicating that large opacity increases are not the rule even in extreme flares. We model the large flare in terms of an analytic 2-Ribbon flare model and find that the flaring loop system should have large characteristic sizes (~1R*). These results are supported by full hydrodynamic simulations. Comparing the large flare to flares of similar size occurring much more frequently on more active stars, we propose that the X-ray properties of active stars are a consequence of superimposed flares such as the example analyzed in this paper. Such a model also explains why, during episodes of low-level emission, more active stars show hotter plasma than less active stars.

description: We provide a complete description of normal affine varieties with effective algebraic torus action in terms of what we call proper polyhedral divisors on semiprojective varieties. Our theory extends classical cone constructions of Dolgachev, Demazure and Pinkham to the multigraded case, and it comprises the theory of affine toric varieties.

description: Agricultural production is clearly an important component of West African international trade, especially of its non-extractive exports. And the improved trade performance of the countries is one of the most important pillars of the regional economic integration process. Thus, the purpose here is to identify determinants of West African international trade flows. For this purpose, the expanded Structural Gravity model was used. The overall pattern of international agricultural transactions in this region is dominated by extra-regional transactions and there are differences between intra- and extra-regional determinants. In global transactions, flows are higher among member countries of the Economic Community of West African States (ECOWAS) and the West African Economic and Monetary Union (WAEMU) does not significantly affect those flows. On the other hand, ECOWAS does not have a significant impact on intra-regional agricultural trade and flows are greater among WAEMU member countries. Geographical distance has no significant effect on West African extra-regional international agricultural trade. Commercial agricultural production of the region s countries is focused on extra-regional trade, which is justified by the regional divergence between supply and demand. In order to increase intra-regional international agricultural transactions, expanding regional agroindustrialization is essential to ensure convergence between supply and demand. Acknowledgement :
