Dysfunctional parenting and suicidal ideation: The moderating role of hostility
No full textChildhood maltreatment stemming from dysfunctional parenting is a well-established risk factor for suicidal
ideation. In turn, dysfunctional parenting has been linked to an increased tendency to develop hostility, which
often relates to self-directed aggression and suicide. However, the interactive role of hostility in shaping the
relationship between dysfunctional parenting and suicidal ideation remains largely understudied, as do the
distinct contributions of maternal and paternal dysfunctional parenting to these associations. The present crosssectional study sought to address these gaps by investigating the moderating role of hostility in the association
between maternal and paternal dysfunctional parenting and suicidal ideation in a large sample of young adults
(N = 683, 539 F). Moderation analyses showed that, in individuals with greater paternal dysfunctional parenting,
higher levels of hostility were associated with greater suicidal ideation, whereas lower levels of hostility were
linked to reduced suicidal ideation. Among those with greater maternal dysfunctional parenting, only the
mitigating role of lower hostility levels on suicidal ideation remained significant. Given that dysfunctional
parenting is a maladaptive interpersonal dynamic and that hostility exacerbates broader interpersonal difficulties, these findings underscore the critical role of the social domain in shaping suicidal ideation. Clinical
interventions that target hostility in young adults with a history of dysfunctional parenting may be effective in
mitigating suicide risk
On the Monotonicity of Relative Entropy: A Comparative Study of Petz’s and Uhlmann’s Approaches
Get PDFWe revisit the monotonicity of relative entropy under the action of quantum channels, a foundational result in quantum information theory. Among the several available proofs, we focus on those by Petz and Uhlmann, which we reformulate within a unified, finite-dimensional operator-theoretic framework. In the first part, we examine Petz’s strategy, identify a subtle flaw in his original use of Jensen’s contractive operator inequality, and point out how it was corrected to restore the validity of his line of reasoning. In the second part, we develop Uhlmann’s approach, which is based on interpolations of positive sesquilinear forms and applies automatically to non-invertible density operators. By comparing these two approaches, we highlight their complementary strengths: Petz’s method is more direct and clear; Uhlmann’s method is more abstract and general. Our treatment aims to clarify the mathematical structure underlying the monotonicity of relative entropy and to make these proofs more accessible to a broader audience interested in both the foundations and applications of quantum information theory
Development of a GEM based diagnostic for Soft X-ray measurements resolved in space, time, and energy at RFX-mod2
No full textSeismically induced kinking in quartz
No full textDeformed quartz veins next (1–1.5 m) to an exhumed pseudotachylyte-bearing (i.e. anciently seismic) fault within the Schobergruppe (Austroalpine Crystalline Complex, Eastern Alps) contain intensely kinked quartz grains. The monoclinic symmetry of kink bands is consistent with the dextral slip sense of the fault. Cathodoluminescence images show a very high density of intragranular, sub-planar, lamellae accompanied by nanometre-scale fluid-related porosity visible in electron backscatter orientation contrast. Based on the oscillating orientation variation across subgrain boundaries (misorientation angle 1–9°) these lamellae (oriented (sub)parallel to a rhomb plane and spaced 4–10 μm apart) are identified as short-wavelength undulatory extinction microstructures (SWUE). Transmission electron microscopy reveals a high degree of recovery (low dislocation density) across the SWUE. Only grains with SWUE oriented parallel to the vein boundary are kinked. Based on detailed microstructural and crystallographic analysis, we infer the following history of kinking evolution related to the seismic cycle: (I) Deformation lamellae formed at high differential stresses preceding, or associated with, seismic rupture propagation. The initial high dislocation density within deformation lamellae provided the mechanical anisotropy in quartz required for (II) the subsequent coseismic initiation of kinking. The lamellae acted as a geometric filter that only allowed r slip of dislocations parallel to the lamellae. These athermal dislocations were able to glide fast over a relatively large distance before piling up and initiating kinking during the coseismic event. Progressive build-up of dislocations resulted in deformation bands which accumulated the final misorientation angle between host domain and kink domain. (III) Residual stress during post-seismic deformation induced dynamic re-arrangement of dislocations into sub-parallel subgrain boundaries which now characterize the kink band boundary region. We suggest that kinking in quartz potentially indicates coseismic deformation and is an important mechanism for incipient strain accommodation during high strain rates
Relational Database in Digital Platforms for Monitoring: Verona Arena Case-study
No full textThe increasing use of sensors and digital technologies in building management requires full integration of information into BIM models. However, few solutions exist that address this challenge organically using relational databases and open formats.This work develops the study of a framework for real-time monitoring of the Verona Arena (Italy) by integrating SHM data from sensors within an IFC model using SQL databases.The paper investigates how to relate different SQL databases of different building domains. Database integration provides a single environment for visualization and analysis of building conditions, improving maintenance and predictive management processes
Capturing CO2 and N2 from the atmosphere: nitrogen-fixing cyanobacteria for sustainable industrial production of proteins
Get PDFThis PhD research project explores the potential of nitrogen-fixing cyanobacteria for sustainable and industrially relevant applications, with a focus on protein production and process optimization. Through an integrated approach combining experimental investigation, process modeling, and techno-economic analysis, this work aims to provide valuable insights into advancing bio-based solutions to global challenges such as food security, environmental sustainability, and resource efficiency. Continuous cultivation in flat panel photobioreactors of diazotrophic cyanobacteria, particularly Nostoc PCC 7120, is investigated as a strategy for stable protein production, with the potential of reducing the reliance on nitrogen fertilisers. Key operating variables are analysed to determine their effect on biomass productivity, quality, and nutritional value. Photorespirometry is employed to evaluate the physiological response of nitrogen-fixing cyanobacteria to light and temperature conditions. A Design of Experiments (DoE) framework is applied to systematically investigate and optimize cultivation conditions, focusing on the interplay between light and nutrient inputs to enhance productivity in high-density cultivation systems. Experimental findings contribute to the development of predictive kinetic models, including variables which are often overlooked like gas insufflation efficiency, establishing a basis for process optimization. The potential of Nostoc sp. as an iron-rich supplement is also investigated as an alternative application in nutraceuticals and functional foods by evaluating iron dynamics in both batch and continuous systems. Finally, based on the laboratory-scale results projected to a real plant scenario, a techno-economic analysis is performed on a one-hectare basis to assess the economic feasibility of the proposed process and explore alternative downstream possibilities
Integrating Building Footprints and Bioenergy Potential to Support Effective Decentralised Energy Planning: A Scalable Framework Based on Open Data
No full textThis study develops a high-resolution workflow to assess rural bioenergy gaps by integrating building-based energy demand and locally collectable biomass supply across Jianghan Plain, China. Building footprint, height and density were extracted from the 10 m 3D-GloBFP dataset and aggregated to 1 km grids to approximate demand intensity. County-level crop straw and livestock manure data were downscaled to generate 1 km supply layers. Subtracting demand from supply yielded a DIFF surface, revealing that 91.8% of rural cells face shortfalls, while only 2.3% are surplus zones, mainly in Songzi, Qianjiang, Tianmen and Xiantao. These counties combine high biomass (> 1200 GJ km−2) with moderate density. Severe deficits (DIFF < −0.25) dominate Honghu and Jianli. Strong negative correlations were found between bioenergy supply and building height (r = −0.74) and footprint area (r = −0.48). The resulting supply–demand atlas enables structural classification and identifies decentralised intervention zones, providing a scalable tool for rural energy planning in mixed-farming regions
The effect of thickness on the Sb2Se3 superstrate solar cells
No full textIn this study, we analyze the impact of different thickness of antimony selenide thin films on the electrical properties of the absorber and on the efficiency of the finished solar cells. Sb2Se3 absorbers have been deposited with different thickness: from 400 nm to 1200 nm, grown by thermal evaporation on CdSe buffer layer in superstrate configuration. The highest efficiency has been delivered by the thinner absorber, with a large absorption spectrum, a higher quantum efficiency response, and a higher carrier concentration. Moreover, a post-annealing treatment in air at 150 °C, improves the efficiency of the cells with a larger impact on the thinnest absorber, increasing the Voc and correcting the rollover effect observed in the current voltage curve of the thicker absorber layers
Energy calibration of the 2.5 MV Pelletron at the Dalton Cumbrian Facility
No full textWe report on the energy calibration of the 2.5 MV Pelletron accelerator at the Dalton Cumbrian Facility in England (UK) using five well-known resonances in the 27Al(p,γ)28Si reaction in the proton beam energy range of 632–1800 keV. The beam energy spread was also measured and found to be 191(38) eV. Additionally, we checked the stability and reproducibility of the accelerator’s beam energy, confirming its suitability for nuclear astrophysics experiments, especially in the high-energy regime of stellar evolution and nucleosynthesis
CHALLENGES IN INTERPRETING CPT FOR RIVER LEVEE MATERIAL CHARACTERIZATION
No full textRiver levees are man-made earthen structures built to prevent flooding, and their failure can result in catastrophic loss of life and economic damage. Despite being artificial, the properties of aging levees are often unknown, especially those constructed decades ago without records of their materials and construction history. Proper geophysical and geotechnical investigations are crucial for characterizing these earthen embankments.The cone penetration test (CPT) is one of the most widely used in-situ techniques for evaluating soil stratigraphy and parameters due to its availability, cost-effectiveness, spatial resolution, and extensive experience base. However, interpreting CPT data for levees is challenging because most of the available procedures were developed for natural, saturated soil deposits rather than the
compacted, unsaturated materials found in levees - an aspect frequently overlooked.This paper critically examines the applicability of CPT for characterizing river levees through real case studies in Italy. Its aim is to guide practitioners and levee managers in properly utilizing CPT for levee assessments to ensure more reliable predictions of embankment vulnerability
