Abstract

The relentless pursuit of understanding matter at ever-finer scales has pushed optical microscopy to surpass the diffraction limit and produced the super-resolution microscopy which enables visualizing structures shorter than the wavelength of light. In the present work, we harnessed extreme ultraviolet beams to create a sub-{\mu}m grating structure, which was revealed by extreme ultraviolet structured illumination microscopy. This achievement marks the first step toward extending such a super-resolution technique into the X-ray regime, where achieving atomic-scale resolution becomes a charming possibility.

Abstract

Invasive fungal infection is a major cause of morbidity and mortality after intensive chemotherapy in patients with leukemia who present with febrile neutropenia. The most common sites of involvement are the lungs, sinonasal region, and disseminated blood stream infection. Visceral organ involvement is usually seen in the form of fungal abscesses, with parenchymal infarcts being less common. We report an unusual case of invasive fungal infection presenting with extensive liver infarction, global renal infarction, and multiple brain lesions in a 4-year-old boy with acute lymphoblastic leukemia on induction chemotherapy.

Abstract

First principles calculations based on density functional theory and many body perturbation theory have been employed to study the optical absorption properties of a newly synthesized oligothiophene molecule, with a quaterthiophene central unit, that has been designed for solutionprocessed bulk-heterojunction solar cells. To this aim we have employed the GW approach to obtain quasiparticle energies as a pre-requisite to solve the Bethe-Salpeter equation for the excitonic Hamiltonian. We show that the experimental absorption spectrum can be explained only by taking into account the inter-molecular transitions among the π-stacked poly-conjugated molecules that are typically obtained in solid-state organic samples.

18. Defects and mechanical properties in weakly damaged Si ion implanted GaAs

Author

Abstract

Damage formation is investigated in GaAs implanted with 1 MeV Si ions to ion fluences from 3 × 10¹² to 5 × 10¹⁵ cm⁻² at room temperature. Under the conditions applied, amorphization of the implanted layers does not occur. The weakly damaged layers are studied by applying different experimental techniques including Rutherford backscattering spectrometry in channeling configuration, x-ray diffraction, in situ curvature measurement, optical subgap spectroscopy, and transmission electron microscopy. The results are evaluated and quantitatively connected with each other. Damage formation is described as a function of the ion fluence using a common defect evolution model. Point defects and defect clusters have to be taken into account in the ion fluence range of main interest up to 2 × 10¹⁵ cm⁻². Point defects contribute by a factor of about 8 more to both perpendicular strain and in-plane stress than defect clusters. When the concentration of point defects or the induced strain reaches a critical value, defect clusters form, which ensures that no further increase of perpendicular strain occurs. This reveals a clear driving force for cluster formation. The microstructure of the defect clusters cannot be determined from the results. As₃Ga₂ interstitial clusters are supposed. A remarkable decrease of the shear modulus of the implanted layers below the value of pristine GaAs by ≈ −35% is observed. Surprisingly, the change of shear modulus already sets in at a very low damage level of a few percent

Abstract

Leading a healthy lifestyle significantly reduces the risk of developing Non-Communicable Diseases (NCD). However, defining and monitoring healthy eating behaviour depends on multiple factors and usually requires the intervention of experts. On the other hand, nowadays millions of images are shared on social media and web platforms. In particular, many of them are food images taken from a smartphone over time, providing information related to the individual’s diet. Consequently, exploiting recent advances in image processing and Artificial Intelligence (AI), this scenario represents an excellent opportunity to: i) create new methods that analyse the individuals’ health from what they eat, and ii) develop personalised recommendations to improve nutrition and diet under specific circumstances (e.g., obesity or COVID). This article introduces the AI4Food-NutritionFW, a framework that facilitates the creation of food image datasets tailored to configurable eating behaviours. The framework considers various aspects such as region and lifestyle, simulating a user-friendly scenario where individuals capture food images using their smartphones. The study also presents a novel food image dataset comprising 4,800 diverse weekly diets from 15 distinct profiles, ranging from healthy eating habits to unhealthy ones. Finally, we evaluate the healthy eating behaviours through a score based on the Normalised Mahalanobis Distance (NMD), achieving promising results (99.53% and 99.60% accuracy and sensitivity, respectively). We also release to the research community a software implementation of our proposed AI4Food-NutritionFW (https://github.com/BiDAlab/AI4Food-NutritionFW) and the mentioned food image dataset created with it.

Abstract

Long-term therapy with low Aspirin (ASA) dose is basis to prevent thrombotic acute events. However, the anti-platelet mechanisms of ASA remain not completely known. The aim was to analyze if in vitro exposure of human megakaryocytes to low ASA concentration may alter the apoptotic features of the newly formed platelets. Cultured Meg-01 cells, a human megakaryoblastic cell line, were stimulated to form platelets with 10 nmol/L phorbol 12-myristate-13-acetate (PMA) in the presence and absence of ASA (0.33 mmol/L). Results revealed that platelet-like particles (PLPs) derived from ASA-exposed Meg-01 cells, showed higher content of pro-apoptotic proteins Bax and Bak than PLPs from non-ASA incubated Meg-01 cells. It was accompanied of reduced cytochrome C oxidase activity and higher mitochondrial content of PTEN-induced putative kinase-1 in PLPs from ASA-incubated Meg-01 cells. However, only after calcium ionophore A23187 stimulation, caspase-3 activity, the cytosolic cytochrome C content, and reduction of mitochondrial membrane potential were higher in PLPs from ASA-incubated megakaryocytes than in those from Meg-01 without ASA. Nitric oxide synthase 3 content was higher in PLPs from ASA-exposed Meg-01 cells than in PLPs from non-ASA incubated Meg-01 cells. The L-arginine antagonist, NG-Nitro-L-arginine Methyl Ester, reduced caspase-3 activity in A23187-stimulated PLPs generated from ASA-incubated Meg-01 cells. As conclusions exposure of megakaryocyte to ASA promotes that the newly generated PLPs have, under stimulating condition, higher sensitivity to go into apoptosis than those PLPs generated from Meg-01 cells without ASA. It could be associated with differences in mitochondrial functionality and NO formation.

Abstract

The AUTODROP model is designed to be dropped out of a ship and be able to manoeuvre autonomously to a fixed point with small uncertainty. During navigation, two phases can be identified: dropping phase and slow down one. The first lasts the great part of falling time and the task is to reach the desired location, the second is the landing, when the model has to reduce its speed, keep the right direction to the target and perform several operations, like unfolding the legs,before touching the seabed. This document describes the first step of the Guidance Control System, its components and functioning. Morover it reports the activity performed at CNR-INSEAN Circulating Water Channel, in order to evaluate forces due to appendages on the Autodrop model and characterize its behaviour during basic manoeuvres.

35. Atomistic Modeling of Gas Adsorption in Nanocarbons

Article Subject
Abstract

Carbon nanostructures are currently under investigation as possible ideal media for gas storage and mesoporous materials for gas sensors. The recent scientific literature concerning gas adsorption in nanocarbons, however, is affected by a significant variation in the experimental data, mainly due to the different characteristics of the investigated samples arising from the variety of the synthesis techniques used and their reproducibility. Atomistic simulations have turned out to be sometimes crucial to study the properties of these systems in order to support the experiments, to indicate the physical limits inherent in the investigated structures, and to suggest possible new routes for application purposes. In consideration of the extent of the theme, we have chosen to treat in this paper the results obtained within some of the most popular atomistic theoretical frameworks without any purpose of completeness. A significant part of this paper is dedicated to the hydrogen adsorption on C-based nanostructures for its obvious importance and the exceptional efforts devoted to it by the scientific community.

During navigation, two phases can be identified: dropping phase and slow down one. The first lasts the great part of falling time and the task is to reach the desired location, the second is the landing, when the model has to reduce its speed, keep the right direction to the target and perform several operations, like unfolding the legs,before touching the seabed. A preliminary estimation of body's and rudder's hydrodynamic forces and moments during a general motion have been computed in order to design, develop and test the Guidance Control System. The document describes the experimental activity performed at INSEAN-CNR towing tank, inorder to evaluate hydrodynamic forces and moments acting on the autodrop model during captive model tests to characterize its behaviour during general motion.

Abstract

Compatibility between biological molecules and inorganic materials, such as crystalline metal oxides, is strongly dependent on the selectivity properties and the adhesion processes at the interface between the two systems. Among the many different aspects that affect the adsorption processes of peptides or proteins onto inorganic surfaces, such as the charge state of the amino acids, the peptide 3D structure, the surface roughness, the presence of vacancies or defects on and below the surface, a key role is certainly played by the water solvent whose molecules mediate the interaction. Then the surface hydration pattern may strongly affect the adsorption behavior of biological molecules. For the particular case of (101) anatase TiO2 surface that has a fundamental importance in the interaction of biocompatible nano-devices with biological environment, it was shown, both theoretically and experimentally, that various hydration patterns are close in energy and that the water molecules are mobile at as low temperature values as 190 K. Then it is important to understand the dynamical behavior of first hydration layer of the (101) anatase surface. As a first approach to this problem, density functional calculations are used to investigate water diffusion on the (101) anatase TiO2 surface by sampling the potential energy surface of water molecules of the first hydration layer thus calculating the water molecule migration energy along some relevant diffusion paths on the (101) surface. The measured activation energy of water migration seems in contrast with the observed surface mobility of the water molecules that, as a consequence could be explained invoking a strong role of the entropic term in the context of the transition state theory.

Author

Olivieri A., Pistani F., La Gala F., Benedetti L., and Penna R

Abstract

Bow and shoulder wave-breaking flow, generated by a fast displacement ship model (INSEAN model 2340) has been investigated. Both the mean and the rms values of wave height have been obtained measuring point by point by means of a finger probe. The intensity of the breaking is highlighted by the highest values of the wave fluctuations nearby the bow wave crest. The velocity field under the free surface has been measured 0.2 Lpp downstream the fore perpendicular by means of 5-hole Pitot probe. The measured velocity field complete the database and highlights interesting flow features. Uncertainty assessement of wave height and velocity results has been performed following the AIAA Standards S071-1995.
