Nothofagus alessandrii forests in the Mediterranean region of chile face significant threats from deforestation, fragmentation, wildfires, and climate change. This study investigated the temporal and spatial dynamics of N. alessandrii populations and their implications for habitat fragmentation and connectivity. Using remote sensing data and geographic information system analysis, we assessed deforestation patterns, fragmentation metrics, and connectivity indices for different scenarios between 2009 and 2022. A reduction in the N. alessandrii forest area, extensive fragmentation, and decreased connectivity were observed over time, with wildfires exacerbating these trends. Reforestation simulations showed the potential of targeted restoration efforts to improve connectivity, especially when focusing on proximate patches. However, careful consideration of seed dispersal distances and wildfire risk is essential for effective reforestation planning. Overall, our findings underscore the urgent need for conservation interventions to preserve N. alessandrii forests and their biodiversity in chile's coastal mountain ecosystems. A proactive and collaborative approach is essential to ensure the survival of these forests for future generations.

Inflammasome links traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease

Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein, an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons. Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates. These misfolded proteins are characteristic of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease and can lead to downstream neuroinflammatory processes, including assembly and activation of the inflammasome complex. Inflammasomes refer to a family of multimeric protein units that, upon activation, release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine. One specific inflammasome, the NOD-like receptor protein 3, has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading. This review begins by describing the epidemiology and pathophysiology of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease. Next, we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain. We then propose a novel framework linking traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease as inflammasomedependent pathologies that exist along a temporal continuum. Finally, we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.

An Emotion Model for Predator-Prey Bird Behavior

International journal of Intelligence Science 2025年第1期15卷 56-78页

作者： Ana Lilia Laureano-cruces André navarro-Bárcenas Ricardo céspedes-Valle Martha Mora-Torres Lourdes Sánchez-Guerrero departamento de Sistemas Universidad Autnoma Metropolitana-Azcapotzalco Ciudad de Mxico Mxico Ingeniera en computacin Universidad Autnoma Metropolitana-Azcapotzalco Ciudad de Mxico Mxico

One of the main objectives of artificial intelligence lies in the simulation of the behavior of living organisms;emotions are a fundamental part of life, and they cannot be left aside when simulating behavior. In this research, software is developed that simulates the behavior of birds with different characteristics. The latter interacts by considering different stimuli from the environment (external), and the internal state of the subject (objectives). To achieve this, a model of birds in the role of prey and predators is developed that focuses on the study of the interaction between these organisms that exhibit specific behaviors in their environment. This project is a seminal work that aims to represent the emotions of birds, and the latter caused by stimuli from a dynamic environment.

Analysis of convective-radiative heat transfer in dovetail longitudinal fins with shape-dependent hybrid nanofluids: a study using the Hermite wavelet method

引用

Applied Mathematics and Mechanics(English Edition) 2025年第2期46卷 357-372页

作者： c.G.PAVITHRA B.j.GIREESHA S.SUSHMA K.j.GOWTHAM department of PG Studies and Research in Mathematics Kuvempu University

A distinguished category of operational fluids, known as hybrid nanofluids,occupies a prominent role among various fluid types owing to its superior heat transfer properties. By employing a dovetail fin profile, this work investigates the thermal reaction of a dynamic fin system to a hybrid nanofluid with shape-based properties, flowing uniformly at a velocity U. The analysis focuses on four distinct types of nanoparticles,i.e., Al2O3, Ag, carbon nanotube (cNT), and graphene. Specifically, two of these particles exhibit a spherical shape, one possesses a cylindrical form, and the final type adopts a platelet morphology. The investigation delves into the pairing of these *** examination employs a combined approach to assess the constructional and thermal exchange characteristics of the hybrid nanofluid. The fin design, under the specified circumstances, gives rise to the derivation of a differential equation. The given equation is then transformed into a dimensionless form. Notably, the Hermite wavelet method is introduced for the first time to address the challenge posed by a moving fin submerged in a hybrid nanofluid with shape-dependent features. To validate the credibility of this research, the results obtained in this study are systematically compared with the numerical simulations. The examination discloses that the highest heat flux is achieved when combining nanoparticles with spherical and platelet shapes.

In this study,we discuss the description of neutral Σ baryons with I(j^(P))=1(1/2^(+))and I(j^(P))=1(3/2^(+))using two bottom-up approaches:the deformed background and static dilaton *** both models,we consider a non-linear Regge trajectory extension motivated by the strange nature of Σ *** find that both models describe these systems with an RMS error smaller than 10%.We also perform a configurational entropy calculation in both models to discuss hadronic stability.
