Cluster scattering in the non-local model

Scattering of weakly bound nuclei with a pronounced cluster structure is strongly affected by their breakup. Usually, this mechanism is accounted for in a three-body model with pairwise potentials. The interaction potentials between complex systems are non-local due to the existence of excitation channels and antisymmetrization. However, a common practice is to use local optical potentials in cluster scattering studies. To assess the validity of replacing non-local optical potentials by their local equivalents, we extend the local-equivalent continuum-discretized coupled-channel (LECDCC) approach proposed by us for deuteron scattering in [Phys. Rev. C98, 011601(R) (2018)] to the case of cluster scattering. We consider the case of 6Li + 120Sn at 27 and 60 MeV, and compare the angular distributions and reaction cross sections for elastic and breakup cross sections with those obtained in the standard continuum-discretized coupled-channel (CDCC) method with local equivalents of non-local potentials. We found that while elastic scattering is not significantly affected by non-locality, the breakup observables could be affected by up to 20% depending on kinematical conditions of their observation.

The Role of Imatinib Mesylate in the Treatment of Metastatic Dermatofibrosarcoma Protuberans: A Case Report and Literature Review

Dermatofibrosarcoma of Darier and Ferrand is a rare cutaneous tumor characterized by its local aggressiveness and high potential for recurrence. It rarely metastasizes, but when it does, the prognosis is poor. Surgery plays a crucial role in the management of these tumors, while targeted therapy is beneficial for metastatic or unresectable forms. Here, we present the case of a 50-year-old female patient who was admitted to our hospital for the management of metastatic dermatofibrosarcoma in the liver. The patient underwent wide excision surgery followed by treatment with imatinib. One-year follow-up showed a good response.

Dimensionless unified modelling of macroscale electric properties of conductive fibre networks in different regimes

The electric properties of conductive fibre networks, which can be representative of carbon nanotube networks, are investigated by means of numerical simulations and a dimensionless unified macroscale model is developed. Fibres are represented as rigid chains of discrete element method particles and we compress systems of fibres in a representative volume element periodic in three dimensions. In the used electric resistor network method, the particles are used as discretisation points to construct a system of linear equations linking the particle conductivities to their local electric potentials and in turn allowing for predictions on the electric macroscale properties of the fibre system. A carried out dimensional analysis suggests suitable scaling laws to unify different macroscale fibre systems in two different regimes - a percolating and a conductive regime. The dimensionless macroscale conductance is found to depend on the percolation threshold and percolation probability. It is moreover found that the critical solid volume fraction for rigid fibres is not only dependent on the fibre aspect ratio, but can also depend on the compression height of the system. Additionally, correlations between transmittance and solid volume fractions are found allowing for possibly simple solid volume fraction estimations in experiments.

3D Modeling and Numerical Investigation of Electrochemical CO2 Reduction in Microfluidic Flow Cells

Electrochemical reduction reaction is considered as a promising technical route for carbon‐neutral and mitigating greenhouse effect. concentration limitation hinders the performance of state‐of‐the‐art electrochemical reduction reaction. Increasing the mass transfer of reactants on the catalyst surface by flow cell design and porous electrode design has become the mainstream approach. Studying the distribution of mass in reaction region is important and beneficial to optimizing and designing efficient reactors. Herein, electrochemical reduction reaction reactors with micrometer and millimeter channels are simulated and systemically analyzed. The results reveal the microfluidic design can improve the mass transfer and reactant gas flow in the porous layer to reduce the concentration polarization and ensure uniform local potential of the reactor. A micrometer channel model requires only 10 sccm inlet gas supply to achieve the same current density compared to a millimeter flow channel with an inlet flow of 20 sccm. This study proposes a reasonable flow channel reactor to reduce gas stagnant region, which not only enhances the reduction performance effectively with evident potential dependence, but also guides the design for large‐scale reactors.

Cities vs countryside: An example of a science-based peri-urban landscape features rehabilitation in Milan (Italy)

Urban-rural boundaries are often abrupt and unmitigated, a trait that significantly enhances their ecological vulnerability. Nonetheless, such fringe systems enclose a high potential in furnishing buffering and resilience functions and services towards the city. Our study intends to give a contribution on the understanding of the ecological behaviour of peri-urban landscape features (PLFs) systems, showing how floristic-vegetational and landscape ecology studies can inform their multi-functional phytocoenoses ecological reconfiguring. Analyses were led among a fringe context of Milan city. An agri-environmental extra-local scale analysis framed the forthcoming finer scale results. Landscape mosaic structural and functional main traits were interpreted, outlining a current impairment of the landscape system capacity to support ecological functions across the area. In parallel, floristic traits were studied through chorological, life forms and Ellenberg’s ecogram analysis (total flora and single sub-areas values). The main phytocoenoses types were qualitatively described and related to the dynamic patterns of reference vegetation series. Results highlighted a significant deterioration of floristic-vegetational traits, if compared to the local potential. Recurrent anthropic disturbances, open space conditions were identified as the major impact factor on phytoconoeses evolution towards higher diversity, complexity and stability traits. Spontaneous recolonization processes were acknowledged as currently unable to change these trends, while past reforestation interventions showed positive effects. These results informed the building of a functional-dynamic interpretative approach, focused on the ecological roles and physical habitat conditions currently influencing phytocoenoses dynamics, and on which to intervene. Accordingly, the current and potential ecological functions of 9 key PLFs categories were inspected. Consequently, design criterions for corrective interventions were outlined. This brought to the identification of the optimal structural and functional patterns of PLFs to be integrated throughout the urban-rural boundary, as well as their floristic-vegetational design specificities, by pursuing a rebalancing effect on the peri-urban agroecosystem inner complexity and environmental stability parameters.

Study on the charge carrier transport property generated by photo/piezo synergy field over barium strontium titanate

The combination of piezoelectric catalysis and photocatalysis has garnered significant attention in the fields of pollutant degradation and water splitting. However, the charge carrier transport property remains unclear due to the difficulty in observing nanocrystal polarization during the reaction process. This study aimed to address this issue by preparing Ba1−xSrxTiO3 (BST) solid solutions using the solid-phase method and examining the effect of ion doping on piezoelectricity-photocatalytic activity. The photocatalysis and local piezoelectric catalysis coupling was evaluated through water decomposition and dye degradation. Interestingly, the introduction of local piezoelectric catalysis had the opposite effect: it reduced photocatalytic hydrogen production but increased the rate of photocatalytic RhB degradation. The possible mechanism was proposed that the different adsorption of H+ and radicals on the catalysts would affect the direction of the local piezoelectric potential and then change the photo-generated carriers' transfer path.

The Retrofitting of the intersection of Nyi Ageng Serang Monument as the Identity of Wates City

The development of a city is inseparable from the city's identity, making the City of Wates need an identity to make it easier to recognize, remember, and to increase the interest of visitors to visit. City's identity can be formed through good regional arrangement and character. The intersection of Nyi Ageng Serang Monument is one of the strategic areas in Wates City which has quite busy traffic conditions and is a commercial area that is the center of the city's economic growth. As a strategic area that had the potential to be the identity of the City of Wates, this area must have good outdoor spatial planning and character. The research aims to develop guideline model based on retrofitting. Data collected through observation and walk-through analysis methods to reveal existing problems and local potential. The model to retrofit are applied based on outdoor spatial planning standards and local potential. Retrofitting of the intersection of Nyi Ageng Serang Monument as the identity of Wates City can be applied through: (1) the arrangement of the corridor spatial planning based on the standard (consisting of street zones, green zones, pedestrian zones, and development zones); and (2) the application of potential local elements in the area to create the character (the shape of building facades, street furniture, colors, and materials).

Variable Support and Opposition to Fuels Treatments for Wildfire Risk Reduction: Melding Frameworks for Local Context and Collaborative Potential

AbstractFuels reduction projects are an increasing focus of policy, funding, and management actions aimed at reducing wildfire risk to human populations while improving landscape health. This research used in-depth interviews to explore variable support or opposition to three fuels-reduction projects occurring in the same region of north central Washington State, USA. Results indicate that differential support or opposition to each project stemmed from a unique combination of social factors operating in each locality (e.g., past history with fuels treatments, values for public land, environmental advocacy networks), the relationships that local populations had with agency members conducting each treatment, and the ways that managers engaged populations in the design of each treatment. We used existing frameworks for understanding collaborative potential/environmental conflict and for documenting the influence of local social context on adaptive wildfire actions to help explain emergent lessons about support or opposition to each project.

The role of nonspecific proteolysis in the development of alterative changes in lung tissue when using electronic cigarettes

In recent years, the number of electronic cigarettes (ES) users has been growing steadily around the world. ES heat and vaporize components of a mixture of propylene glycol, vegetable glycerin, nicotine, and flavors. Reports of severe forms of lung injury caused by the use of ES, some of which have resulted in death, urge studying the pathogenetic mechanisms of such complications. One of the mechanisms is the activation of nonspecific proteolysis accompanied by the destruction of connective tissue components of the blood-air barrier.Aim of the study. To study the dynamics of the proteinase-inhibitor system indicators and its role in the morphological changes of lung tissue in experimental modeling of the effects of ES.Methods. Experimental studies were performed in 24 white male Wistar rats weighing 160 – 180 g. ES use of was simulated by intermittent exposure to smoke mixture vapors using a POD system connected to a two-channel compressor.Results. Analysis of the state of the nonspecific proteinase inhibitory system in rat broncho-alveolar lavage and blood serum and the results of morphological studies indicate activation of trypsin-like proteinases and depletion of the local antitryptic potential, leading to biochemical changes with subsequent structural changes in lung tissue. The latter are characterized by congestion, leukocyte infiltration, and stromal proliferation. In addition, exposure to nicotine-containing mixtures has been shown to affect the proteinase inhibitory system and blood serum composition, which is associated with a compensatory increase in antitrypsin activity.Conclusion. The results of the study indicate the activation of trypsin-like proteinases in broncho-alveolar lavage, which have a damaging effect on lung tissue, leading to disturbances in tissue hemodynamics, extravasation of leukocytes, remodeling and thickening of the blood-air barrier.

Erratum: Anyon braiding on a fractal lattice with a local Hamiltonian [Phys. Rev. A 105 , L021302 (2022)

There is a growing interest in searching for topology in fractal dimensions with the aim of finding different properties and advantages compared to the integer dimensional case. Here, we construct a local Hamiltonian on a fractal lattice whose ground state exhibits topological braiding properties. The fractal lattice is obtained from a second generation Sierpinski carpet with Hausdorff dimension 1.89. We use local potentials to trap and exchange anyons in the model, and the numerically obtained results for the exchange statistics of the anyons are close to the ideal statistics for quasiholes in a bosonic Laughlin state at half filling. For the considered system size, the energy gap is about three times larger for the fractal lattice than for a two-dimensional square lattice, and we find that the braiding results obtained on the fractal lattice are more robust against disorder. We propose a scheme to implement both fractal lattices and our proposed local Hamiltonian with ultracold atoms in optical lattices.

Leveraging RIS-Enabled Smart Signal Propagation for Solving Infeasible Localization Problems: Scenarios, Key Research Directions, and Open Challenges

Reconfigurable intelligent surfaces (RISs) have tremendous potential for both communication and localization. While communication benefits are now well understood, the breakthrough nature of the technology may well lie in its capability to provide and support localization capabilities. We present an overview of RIS-enabled localization scenarios, considering various numbers of RISs, single- or multi-antenna base stations, narrowband or wideband transmissions, and near- and far-field operations. Based on this overview, we also highlight key research directions and open challenges specific to RIS-enabled localization and sensing.

Socioeconomic and demographic factors on academic center accessibility in sebaceous adenocarcinoma: An NCDB analysis.

e21501 Background: Sebaceous adenocarcinoma (SA) is a rare, aggressive adnexal tumor shown to have both local and distant metastatic potential. The 5-year overall survival rate for this cancer is 78% for localized/regional disease and 50% for metastatic disease. Improved survival in other skin malignancies, such as melanoma, has been previously linked to treatment at academic cancer centers. The National Cancer Database (NCDB) was analyzed to determine variables impacting treatment at academic versus non-academic facility types in SA. Methods: A retrospective cohort analysis using the NCDB from 2004 to 2019 included patients diagnosed with histologically confirmed SA (N = 3,378). Socio-demographic factors (sex, age, race, Hispanic status, insurance type, urban/rural designation, facility location, education, income, distance from facility, and Charlson-Deyo score) were analyzed using Pearson Chi-squared tests and multivariate analysis of factors on academic center accessibility (facility type) was performed via binary logistic regression. A significance level of 0.05 was used. Results: The number of cases diagnosed with SA has steadily increased from 2004 to 2019 (152 and 287, respectively, R2 = 0.894). Most patients were male (59.1%), White (89.8%), not Hispanic (89.6%), insured (95.7%), and lived in an urban area (98.4%). There was a statistically significant difference between sex, race, insurance type, urban/rural designation, facility location, education, income, and distance from residence to the facility on academic facility type. Male patients were 1.3 times more likely to access academic centers compared to female patients (p < 0.001, CI = [0.681 - 0.911]). Patients with median household incomes in the top quartile were also 2.2 times more likely than those in the bottom quartile to receive treatment at an academic center (p < 0.001, CI = [1.676 - 2.992]). Conclusions: There has been an upward trend in the diagnosis of SA since 2004 with a predilection for White males. Female patients and patients with a lower income are less likely to receive treatment at an academic center. Given the rarity of the disease, this study serves as a valuable tool for understanding the factors associated with facility-type access. Future studies aim to determine the effect of academic center type on overall survival. Additional research is needed to understand the difference in treatment at academic versus non-academic facilities.
