description: For a periodic structure sandwiched between two homogeneous media, a bound state in the continuum (BIC) is a guided Bloch mode with a frequency in the radiation continuum. Optical BICs have found many applications, mainly because they give rise to resonances with ultra-high quality factors. If the periodic structure has a relevant symmetry, a BIC may have a symmetry mismatch with incoming and outgoing propagating waves of the same frequency and compatible wavevectors, and is considered as protected by symmetry. Propagating BICs with nonzero Bloch wavevectors have been found on many highly symmetric periodic structures. They are not protected by symmetry in the usual sense (i.e., there is no symmetry mismatch), but some of them seem to depend on symmetry for their existence and robustness. In this paper, we show that the low-frequency propagating BICs (with only one radiation channel) on biperiodic structures with an inversion symmetry in the plane of periodicity and a reflection symmetry in the perpendicular direction are robust to symmetry-preserving structural perturbations. In other words, a propagating BIC continues its existence with a slightly different frequency and a slightly different Bloch wavevector, when the biperiodic structure is perturbed slightly preserving the inversion and reflection symmetries. Our study enhances theoretical understanding for BICs on periodic structures and provides useful guidelines for their applications.

description: Neurosensory retinal detachment is a rare ocular finding in acute myeloid leukemia. We describe a case of a 25 year-old female with history of acute myeloid leukemia under chemotherapy that was referred to the Ophthalmology Department due to blurred vision and metamorphopsia in the left eye for the last two weeks. On examination, there was an oval, high, paracentral lesion, superior to the macula with adjacent small hemorrhage. She performed macular spectral domain optic coherence tomography that showed macular edema with neurosensory detachment, fluorescein angiography that revealed a multifocal diffusion with hyperfluorescence and indocyanine green hypofluorescent spots suggesting choroidal ischemia. A diagnosis of neurosensorial retinal detachment that revealed a choroidal infiltration was made. The chemotherapy was continued and, one month after, progressive visual improvement was identified. A systemic disease with atypical retinal findings should alert to diagnose extramedullary disease and a multidisciplinary approach is necessary.

description: Raw materials used in the food processing industry must have specific properties for specified end uses. As specialization of food processing increases and as new food products are developed, the raw materials used in producing these food products are less easily substituted. The following article illustrates how this trend affects wheat utilization. This has implications in agricultural policy, marketing, and research. A lack of recognition of product properties can lead to loss of export markets, reduced farm income, and a continued decline in per capita consumption of wheat products. Economists often are unaware of product properties. As a result, some food consumption data include food items within a group which require different agricultural raw materials. In this paper an attempt is made to separate wheat foods according to the types of wheat required to produce them. While this research relates to wheat utilization in the domestic market, it has significance to markets for other agricultural commodities as well as wheat exports.

description: Metallicities ([Fe/H]) from low resolution spectroscopy obtained with the Very Large Telescope (VLT) are presented for 98 RR Lyrae and 3 short period Cepheids in the bar of the Large Magellanic Cloud. Our metal abundances have typical errors of +/-0.17 dex. The average metallicity of the RR Lyrae stars is [Fe/H]=-1.48 +/- 0.03 +/- 0.06 on the scale of Harris (1996). The star-to-star scatter (0.29 dex) is larger than the observational errors, indicating a real spread in metal abundances. The derived metallicities cover the range -2.12 < [Fe/H] -1. For the ab-type variables we compared our spectroscopic abundances with those obtained from the Fourier decomposition of the light curves. We find good agreement between the two techniques, once the systematic offset of 0.2 dex between the metallicity scales used in the two methods is taken into account. The spectroscopic metallicities were combined with the dereddened apparent magnitudes of the variables to derive the slope of the luminosity-metallicity relation for the LMC RR Lyrae stars: the resulting value is 0.214 +/- 0.047 mag/dex. Finally, the 3 short period Cepheids have [Fe/H] values in the range -2.0 < [Fe/H]

description: Scattering of time-harmonic plane wave by two parallel semi-infinite rows, but with staggered edges, is considered on square lattice. The condition imposed on the semi-infinite rows is a discrete analogue of Neumann boundary condition. A physical interpretation assuming an out-of-plane displacement for the particles arranged in the form of a square lattice and interacting with nearest-neighbours, associates the scattering problem to lattice wave scattering due to the presence of two staggered but parallel crack tips. The discrete scattering problem is reduced to the study of a pair of Wiener-Hopf equation on an annulus in complex plane, using Fourier transforms. Due to the offset between the crack edges, the Wiener-Hopf kernel, a 2x2 matrix, is not amenable to factorization in a desirable form and an asymptotic method is adapted. Further, an approximation in the far field is carried out using the stationary phase method. A graphical comparison between the far-field approximation based on asymptotic Wiener-Hopf method and that obtained by a numerical solution is provided. Also included is a graphical illustration of the low frequency approximation, where it has been found that the numerical solution of the scattering problem coincides with the well known formidable solution in the continuum framework.

description: This paper investigates whether an inefficient allocation of abatement, due to constraints on the use of currently available low carbon mitigation options, can promote innovation in new technologies and eventually generate welfare gains. We focus on the case of nuclear power phase out, when accounting for endogenous technical change in energy efficiency and in low carbon technologies. The analysis uses the Integrated Assessment Model WITCH, which features multiple externalities due to both climate and innovation market failures. Our results show that phasing out nuclear power stimulates additional R&D investments and deployment of infant technologies with large learning potential. The innovation benefits which this would generate and that would not otherwise be captured due to intertemporal and international externalities almost completely offset the economic costs of phasing out nuclear power. The technological change benefit depends on the stringency of the climate policy and is distributed unevenly across countries.

description: Hypernormalisation, a term originally coined by Alexei Yurchak to describe the paradoxical stability of a dysfunctional Soviet system, now resonates in our post-truth era. This article critically reflects on how contemporary society, politics, and technology construct a façade of normalcy while deep-seated contradictions remain unaddressed. By examining historical origins, media influences, and modern manifestations, we explore why challenging hypernormalisation is essential for reclaiming authentic public discourse and fostering meaningful societal change.

description: When it comes to environmental quality preferences, it is popularly believed that Democrats (and more generally, liberals) are “green” while Republicans” (conservatives) are “brown”. Does empirical evidence support this popular belief? We test the hypothesis that regional political identification leads to differences in concentration outcomes for several measures of California air pollution indicators, including CO, NO2, SO2, O3, PM10, and PM2.5 concentrations. We employ two alternative identification strategies on county-level cluster and year panel data that include proxy variables for political party preferences of the local populace, as well as controlling for the political party affiliations at the state-level legislative and executive branches. In general, we do not find a consistent and statistically significant relationship between pollution outcomes and political variables for California. The popular belief is empirically supported only for NO2 and O3, but not for any of the other pollutants, and even in these two cases the relationship only holds at the local regulatory level and not at the state policymaking level. At the state level, for most of the pollutants no significant effect of party affiliation is identified, and in the rare cases where such an effect exists, it is either too weak to be conclusive or is even counter to popular belief.

description: Considerable debate exists about the causes of psychological gender differences and the effects of gendered socialisation and other societal factors. The aim of this PhD project was to investigate the impact of gendered socialisation and gender equality on psychological gender differences using both primary and secondary datasets. Chapter 1 provides a broad overview of the relevant academic literature. In Chapter 2, I have presented a meta-analysis on the correlation between national levels of gender equality and the gender gap in children’s mathematics performance, finding no significant overall correlation and thus no support for the existence of a ‘gender equality paradox’ in this area. In Chapter 3, I then investigated whether individual-level factors could be contributing to gender differences by conducting a study on the relationship between gender, feelings of imposterism, self-efficacy and belonging in a sample of university students. I found that women on average experienced higher levels of imposterism, which was linked to low levels of self-efficacy, but not to feelings of belonging. In Chapter 4, I examined the relationship between adult gender division and gendered childhood socialisation in non-industrialised societies using existing ethnographic data, finding that higher adult gender division correlated with larger gender differences in how much adults try to instil different traits in boys and girls. Finally, in Chapter 5, I conducted a study employing a priming paradigm, gathering empirical data on the potential effects priming participants about levels of gender equality on their romantic partner preferences. I found a significant relationship between partner preferences and self-reported feminist attitudes but not an effect of the priming material. The results of this thesis indicate that while socialisation and gender equality do seem to impact gender differences, their effects are not always consistent or straightforward.

description: We use a panel of European firms to investigate the relationship between intangible assets and productivity. We disentangle between tfp and technology adoption, while available studies so far have considered only a notion of productivity conflating the two effects. To this aim, we estimate production function parameters allowing, within each sector, for the existence of multiple technologies. We find that intangible assets both push the firm towards better technologies (technology adoption effects) and allow for a more efficient exploitation of a given technology (tfp effects).

description: Segment Routing (SR) is a modern paradigm for traffic engineering and network optimization that offers enhanced scalability and flexibility compared to traditional MPLS and IP-based routing. This paper explores models and algorithms for optimizing network performance using SR, focusing on path computation, resource allocation, and traffic engineering strategies. We examine integer linear programming (ILP) formulations, heuristic approaches, and machine learning-based methods to improve the efficiency of SR-based networks. Additionally, we discuss real-world deployment challenges, architectural considerations, and the integration of SR with emerging network technologies. Furthermore, we analyze network resilience techniques, fault tolerance mechanisms, and energy-efficient routing strategies that can enhance the sustainability of SR deployments. We also address optimization in multi-domain environments, cross-layer design approaches, and the role of SR in autonomous networks.

description: Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between “dirty” (internal combustion engine) and “clean” (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms tend to innovate relatively more in clean technologies when they face higher tax-inclusive fuel prices. Furthermore, there is path dependence in the type of innovation both from aggregate spillovers and from the firm's own innovation history. Using our model we simulate the increases in carbon taxes needed to allow clean to overtake dirty technologies.

description: Can three-dimensional, microvasculature networks still ensure blood supply if individual links fail? We address this question in the sinusoidal network, a plexus-like microvasculature network, which transports nutrient-rich blood to every hepatocyte in liver tissue, by building on recent advances in high-resolution imaging and digital reconstruction of adult mice liver tissue. We find that the topology of the three-dimensional sinusoidal network reflects its two design requirements of a space-filling network that connects all hepatocytes, while using shortest transport routes: sinusoidal networks are sub-graphs of the Delaunay graph of their set of branching points, and also contain the corresponding minimum spanning tree, both to good approximation. To overcome the spatial limitations of experimental samples and generate arbitrarily-sized networks, we developed a network generation algorithm that reproduces the statistical features of 0.3-mm-sized samples of sinusoidal networks, using multi-objective optimization for node degree and edge length distribution. Nematic order in these simulated networks implies anisotropic transport properties, characterized by an empirical linear relation between a nematic order parameter and the anisotropy of the permeability tensor. Under the assumption that all sinusoid tubes have a constant and equal flow resistance, we predict that the distribution of currents in the network is very inhomogeneous, with a small number of edges carrying a substantial part of the flow. We quantify network resilience in terms of a permeability-at-risk, i.e.\ permeability as function of the fraction of removed edges. We find that sinusoidal networks are resilient to random removal of edges, but vulnerable to the removal of high-current edges. Our findings suggest the existence of a mechanism counteracting flow inhomogeneity to balance metabolic load on the liver.

description: A new suggestion for pattern formation in biological systems is proposed. The interaction of two signaling pathways provides complex patterning. The interaction of two pathways involves few of the biochemical complexities of the pathways. The 'Wnt' pathway is proposed to be one of these, in interaction with others, one at a time, perhaps sequentially, such as Hunchback (Hh), Notch, BMP, etc., those involved in development of metazoa. It is further shown how such interactions can easily lead to such epithelial movements as gastrulation. Numerical simulations of the model are given.

description: Aggression is an adaptive social behavior crucial for the stability and prosperity of social groups. When uncontrolled, aggression leads to pathological violence that disrupts group structure and individual wellbeing. The comorbidity of uncontrolled aggression across different psychopathologies makes it a potential endophenotype of mental disorders with the same neurobiological substrates. Serotonin plays a critical role in regulating impulsive and aggressive behaviors. Mice lacking in brain serotonin, due to the ablation of tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme in serotonin synthesis, could serve as a potential model for studying pathological aggression. Home cage monitoring allows for the continuous observation and quantification of social and non-social behaviors in group-housed, freely-moving mice. Using an ethological approach, we investigated the impact of central serotonin ablation on the everyday expression of social and non-social behaviors and their correlations in undisturbed, group-living Tph2 -deficient and wildtype mice. By training a machine learning algorithm on behavioral time series, “allogrooming”, “struggling at feeder”, and “eating” emerged as key behaviors dissociating one genotype from the other. Although Tph2 -deficient mice exhibited characteristics of pathological aggression and reduced communication compared to wildtype animals, they still demonstrated affiliative huddle behaviors to normal levels. Altogether, such a distinct and dynamic phenotype of Tph2 -deficient mice influenced the group's structure and the subsequent development of its hierarchical organization. These aspects were analyzed using social network analysis and the Glicko rating methods. This study demonstrates the importance of the ethological approach for understanding the global impact of pathological aggression on various aspects of life, both at the individual and group levels. Home cage monitoring allows the observation of the natural behaviors of mice in a semi-natural habitat, providing an accurate representation of real-world phenomena and pathological mechanisms. The results of this study provide insights into the neurobiological substrate of pathological aggression and its potential role in complex brain disorders.

Methods and Materials: Case report. Results: A female patient with 59 years old, with history of longstanding rheumatoid arthritis, presented with redness and photophobia in the right eye. As past ocular history, the patient had a severe keratoconjunctivitis sicca and a corneal ulcer in the right eye. Clinical examination revealed an epithelial defect with a significant inferior corneal thickness decrease. Topical steroids, antibiotics and a therapeutic contact lens were prescribed. One month later, a corneal perforation was observed and a crescent-shaped deep anterior lamellar keratoplasty was then performed. Conclusion: The clinical course of peripheral ulcerative keratitis depends on the associated systemic pathology, being essential a multidisciplinary approach by ophthalmologists and rheumatologists to allow systemic control of the autoimmune disease, avoiding possible complications such as eye perforation.

description: With the important role of the gut microbiome in health and disease, it is crucial to understand key factors that establish the microbial community, including gut colonization during infancy. It has been suggested that the first bacterial exposure is via a placental microbiome. However, despite many publications, the robustness of the evidence for the placental microbiome and transfer of bacteria from the placenta to the infant gut is unclear and hence the concept disputed. Therefore, we conducted a systematic review of the evidence for the role of the placental, amniotic fluid and cord blood microbiome in healthy mothers in the colonization of the infant gut. Most of the papers which were fully assessed considered placental tissue, but some studied amniotic fluid or cord blood. Great variability in methodology was observed especially regarding sample storage conditions, DNA/RNA extraction, and microbiome characterization. No study clearly considered transfer of the normal placental microbiome to the infant gut. Moreover, some studies in the review and others published subsequently reported little evidence for a placental microbiome in comparison to negative controls. In conclusion, current data are limited and provide no conclusive evidence that there is a normal placental microbiome which has any role in colonization of infant gut.

More than 300 political scientists participated. The experts provided estimates for the relevant German parties on various dimensions and policy issues. They also assessed the salience of specific topics for the parties. Two aspects make the OES21 stand out against other expert surveys. First, it provides party placements on multiple issues, many of which are not asked in existing expert surveys. Second, the number of experts is comparatively large, allowing to analyze in greater detail how expert characteristics affect party placement.

description: Introduction and purpose: ROPScore is a scoring system that was proposed to predict severe retinopathy of prematurity (ROP) using easily obtainable parameters as predictive variables. The aim of this study is to assess the accuracy of the ROPScore algorithm as a predictor of ROP by the second week of life. Materials and Methods: Retrospective cohort study of 239 preterm infants with a gestational age (GA) ≤ 32 weeks and/or birthweight (BW) ≤ 1500 g. No ROP, any stage of ROP and severe ROP requiring treatment were categorized. ROPScore was calculated in the second week of life using the following parameters: GA, BW, weight by the second week of life, use of oxygen in mechanical ventilation and use of blood transfusions. Sensitivity, specificity and positive (PPV) and negative (NPV) predictive values were calculated. The best cut-offs of the algorithm were calculated and, whenever possible, a sensitivity of 100% was chosen. Results: Mean BW was 1241.6 ± 310.0g and mean GA was 29.8 ± 3.4 weeks. Of the 239 infants, ROP was identified in 101 (42.3%) and 12 (11.9%) had severe ROP requiring treatment. Mean ROPScore was 15.39 ± 1.94 in the any stage of ROP cohort and 17.52 ± 1.80 in the severe ROP cohort. The sensitivity of the algorithm was 96.0% and 100% for any stage of ROP and severe ROP, respectively. NPV was 92.3% and 100% for any stage of ROP and severe ROP, respectively. Conclusion: ROPScore is a simple public domain algorithm that can be applied as early as by the second week of life. It may be used as a reliable screening tool for ROP and optimize examination timings, but further validation is required.

description: Measurements serve as the intermediate communication layer between the quantum world and our classical perception. So, the question which measurements efficiently extract information from quantum systems is of central interest. Using quantum steering as a nonclassical phenomenon, we show that there are instances, where the results of all two-outcome measurements can be explained in a classical manner, while the results of some three-outcome measurements cannot. This points at the important role of the number of outcomes in revealing the nonclassicality hidden in a quantum system. Moreover, our methods allow to improve the understanding of quantum correlations by delivering novel criteria for quantum steering and improved ways to construct local hidden variable models.

description: We explore the ways in which primordial magnetic fields influence the thermal and ionization history of the post-recombination universe. After recombination the universe becomes mostly neutral resulting also in a sharp drop in the radiative viscosity. Primordial magnetic fields can then dissipate their energy into the intergalactic medium (IGM) via ambipolar diffusion and, for small enough scales, by generating decaying MHD turbulence. These processes can significantly modify the thermal and ionization history of the post-recombination universe. We show that the dissipation effects of magnetic fields which redshifts to a present value $B_{0}=3\times 10^{-9}$ Gauss smoothed on the magnetic Jeans scale and below, can give rise to Thomson scattering optical depths $τ\ga 0.1$, although not in the range of redshifts needed to explain the recent WMAP polarization observations. We also study the possibility that primordial fields could induce the formation of subgalactic structures for $z \ga 15$. We show that early structure formation induced by nano-Gauss magnetic fields is potentially capable of producing the early re-ionization implied by the WMAP data. Future CMB observations will be very useful to probe the modified ionization histories produced by primordial magnetic field evolution and constrain their strength.

description: We report on fabrication and characterization of field effect transistors (FETs) on single-crystal pentacene. These FETs exhibit hole conductivity with room temperature effective mobility up to 0.30 cm2/Vs and on/off ratios up to 5*10^6. A negative gate voltage of -50V significantly decreases the activation energy (Ea) down to 0.143 eV near room temperature. Assuming thermal equilibrium between trapped and free carriers, from Ea = 0.143eV, we find the number of free carriers is only 0.4% of the total number of injected carriers. Along with effective mobility ~ 0.3 cm2/Vs this gives the intrinsic free carrier mobility of ~75 cm2/Vs.

description: Polymyxins, especially polymyxin B and polymyxin E (colistin), are considered to be the last line of defence against infections caused by multi-drug-resistant (MDR) gram-negative bacteria such as carbapenem-resistant Enterobacteriaceae (CRE). However, the recent emergence and dissemination of the plasmid-mediated colistin resistance gene mcr-1 and its variants pose a serious challenge to public health and the livestock industry. This review describes the prevalence and dissemination of mcr-1-positive isolates from different sources, including animals (food animals, pet animals and wildlife), humans (healthy populations and patients) and the environment (farms, urban and rural communities and natural environments) based on existing epidemiological studies of mcr-1 and MCR-1-producing Enterobacteriaceae bacteria around the world. The major mechanisms of mcr-1 transmission across humans, animals and the environment are discussed.

description: Purpose Visual rehabilitation is an important part of keratoconus treatment. Glasses or contact lenses are usually sufficient in mild cases. Advanced disease may require surgical treatment. Intrastromal corneal ring segments (ICRS) implantation is an effective treatment. However, surgical planning is in constant evolution and the visual results are hard to predict. We aim to assess predictive factors of the visual results, determining the best cases for this treatment. Material and Methods: Retrospective analysis of successful ICRS implantation in our hospital. Refractive and topographical data in pre and postoperative setting was analyzed in order to identify predictive factors for success. INTACS-SK® ring segments were used, according to the plan recommended by the manufacturer. Results Sixty-five surgeries were analyzed. Both uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) showed significant improvement after surgery (0.11±0.11 to 0.28±0.20 and 0.48±0.22 to 0.63±0.20, respectively). Refractive and keratometric values also improved significantly. BCVA improved in 43 eyes (67%), with gain of at least 2 Snellen lines in 28 eyes (43%). Post-op BCVA was negatively correlated with pre-op refraction, corneal thickness and corneal curvature. Visual improvement was negatively correlated with pre-op corneal astigmatism and steep K. Patients with steep K lower than 47.5D and corneal astigmatism lower than 3.75D had better results. Conclusions ICRS implantation is effective in improving visual acuity, refraction and corneal shape. Eyes with more advanced disease (higher astigmatism and corneal curvature) have worse results, perhaps being better suited for other treatments, such as keratoplasty. It is possible that a different type of ring segment or improved surgical planning could improve the results.

description: The purpose of this proposal is to explore a new concept of 'Metadistrict' to be applied in a region of Southern Italy – Apulia - in order to analyze the impact that the activation of a special network between different sector chains and several integrated projects may have for revitalizing the local economy. The Metadistrict model stems from the LAGs and the IPFs frameworks and it may represent a crucial driver of the rural economy through the realization of sector circuits connected to the concept of multi-functionality in agriculture, that is Network of the Territorial Multi-functionality (NTM). It was formalized through a simplified model based on Matrix Organization. The adoption of the Metadistrict perspective as the territorial strategy may play a key role to revitalize the primary sector through the increase of economic and productive opportunities due to the implementation of a common and shared strategy and organization.
