AIM: To study whether the concentrations of particulate matter in ambient air are associated with hospitaladmission due to heart failure in patients with heart failure with preserved ejection fraction and reduced ejection fraction. METHODS: We studied 353 consecutive patients admitted into a tertiary care hospital with a diagnosis of heart failure. Patients with ejection fraction of ≥ 45% were classified as having heart failure with preserved ejection fraction and those with an ejection fraction of < 45% were classified as having heart failure with reduced ejection fraction. We determined the average concentrations of different sizes of particulate matter (< 10, < 2.5, and < 1 μm) and the concentrations of gaseous pollutants (carbon monoxide, sulphur dioxide, nitrogen dioxide and ozone) from 1 d up to 7 d prior to admission. RESULTS: The heart failure with preserved ejection fraction population was exposed to higher nitrogen dioxide concentrations compared to the heart failure with reduced ejection fraction population (12.95 ± 8.22 μg/m 3 vs 4.50 ± 2.34 μg/m 3 , P < 0.0001). Multivariate analysis showed that nitrogen dioxide was a significant predictor of heart failure with preserved ejection fraction (odds ratio ranging from (1.403, 95%CI: 1.003-2.007, P = 0.04) to (1.669, 95%CI: 1.043-2.671, P = 0.03). CONCLUSION: This study demonstrates that shortterm nitrogen dioxide exposure is independently associated with admission in the heart failure with preserved ejection fraction population.

We review the two-zero mass matrix textures approach for Dirac neutrinos with the most recent global fit in the oscillation *** found that three of the 15 possible textures are compatible with current experimental data,while the remaining two-zero textures were ruled *** textures are consistent with the normal hierarchy of neutrino masses and are CP-conserving,while the other is compatible with both mass orderings and allows for CP *** also present the correlations between the oscillation parameters for the allowed two-zero textures.

The objective of this study is to present a tailings recovery project in a dam located in northern Brazil;the tailings in this dam have high concentrations of iron. The sustainable recovery of mineral resources can be achieved using the dredging method. The methodology used was based on two drilling projects conducted in 2001 and 2010;these projects contained samples with information on the chemical composition and particle size fractions. The dredging system was designed to operate with four cutter suction dredgers. For operation, factors such as productivity, pumping distance and material flow were considered. The material contained in the dam was estimated using the natural neighborhood interpolation method;this resulted in approximately 192 million tons of tailings, with an average iron content of 63.37%. Based on these data, a 13-year mining plan was prepared, with the potential to maximize the use of the tailings and reduce the environmental impacts, thus contributing to a circular economy.

A parametrization of density matrices of ddimensions in terms of the raising J+and lowering J−angular momentum operators is established together with an implicit connection with the generalized Bloch-GellMann parameters. A general expression for the density matrix of the composite system of angular momenta j1and j2is obtained. In this matrix representation violations of the Bell-Clauser-Horne-Shimony-Holt inequalities are established for the X-states of a qubit-qubit, pure and mixed, composite system, as well as for a qubit-qutrit density matrix. In both cases maximal violation of the Bell inequalities can be reached, i.e., the Cirel’son limit. A correlation between the entanglement measure and a strong violation of the Bell factor is also given. For the qubit-qutrit composite system a time-dependent convex combination of the density matrix of the eigenstates of a two-particle Hamiltonian system is used to determine periodic maximal violations of the Bell’s inequality.

Background: Surgical treatment of lumbar disc herniation is a widely debated topic, with several techniques available. Percutaneous endoscopic discectomy (PELD) has gained popularity due to its lower invasiveness compared to conventional techniques such as microdiscectomy/open lumbar microdiscectomy (OLMD)/tubular microdiscectomy (TMD). However, evidence on the effectiveness, recovery time and complications of these techniques is not yet clearly established. This systematic review aims to compare the preoperative and postoperative outcomes of both techniques. Methods: A comprehensive search was performed in databases including PubMed and Cochrane, following strict inclusion and exclusion criteria. Comparative studies and narrative reviews on PELD and OLMD/TMD published between 2019 and 2024 were included. Key outcomes considered were pre- and postoperative Visual Analogue Scale (VAS), hospitalization time, time to return to work, and postoperative complications. Results: The reviewed studies indicated that PELD is associated with a greater reduction in postoperative pain compared to OLMD/TMD, with a significant decrease in VAS, according to the study by Priola et al. (2019). The hospital stay was also shorter for patients undergoing PELD, averaging 2 days compared to OLMD/TMD. Furthermore, PELD favored a faster return to work and had a lower rate of postoperative complications, such as dural tears and reoperations, compared to OLMD/TMD. Conclusions: PELD demonstrates clear advantages over OLMD/TMD in terms of pain reduction, shorter hospital stay, faster return to work, and fewer postoperative complications. However, the implementation of this technique requires a significant learning curve, suggesting that its effectiveness may vary depending on the surgeon’s experience. PELD should be considered a preferred option in the resection of lumbar disc herniations, especially in patients seeking a quick and less invasive recovery.

This work deals with a three-dimensional system, which describes a food web model consisting of a prey, a specialist predator and a top predator which is generalist as it consumes the other two species. Using tools of dynamical systems we prove that the trajectories of system are bounded and that open subsets of parameters exist, such that the system in the first octant has at most two singularities. For an open subset of the parameters space, the system is shown to have an invariant compact set and this is a topologically transitive attractor set. Finally, we find another open set in the parameters space, such that the system has two limit cycles each contained in different invariant planes. The work is completed with a numeric simulation showing the attractor is a strange attractor.

Our application of bionic engineering is novel： we are interested in developing hybrid hardware-wetware systems for music. This paper introduces receptacles for culturing Physarum polycephalum-based memristors that are highly accessible to the creative practitioner. The myxomycete Physarum polycephalum is an amorphous unicellular organism that has been found to exhibit memristive properties. Such a discovery has potential to allow us to move towards engineering electrical systems that encompass Physarum polycephalum components. To realise this potential, it is necessary to address some of the constraints associated with harnessing living biological entities in systems for real-time application. Within the paper, we present 3D printed receptacles designed to standardise both the production of components and memristive observations. Subsequent testing showed a significant decrease in growth time, increased lifespan, and superior similarity in component-to-component responses. The results indicate that our receptacle design may provide means of implementing hybrid electrical systems for music technology.
