Human activities in many parts of the world have greatly affected natural areas. Therefore, monitoring and forecasting of land-cover changes are important components for sustainable utilization, conservation, and development of these areas. This research has been conducted on Igneada, a legally protected area on the northwest coast of Turkey, which is famous for its unique, mangrove forests. The main focus of this study was to apply a land use and cover model that could quantitatively and graphically present the changes and its impacts on Igneada landscapes in the future. In this study, a Markov chain-based, stochastic Markov model and cellular automata Markov model were used. These models were calibrated using a time series of developed areas derived from Landsat Thematic Mapper (TM) imagery between 1990 and 2010 that also projected future growth to 2030. The results showed that CA Markov yielded reliable information better than St. Markov model. The findings displayed constant but overall slight increase of settlement and forest cover, and slight decrease of agricultural lands. However, even the slightest unsustainable change can put a significant pressure on the sensitive ecosystems of Igneada. Therefore, the management of the protected area should not only focus on the landscape composition but also pay attention to landscape configuration.

Speech comprehension involves the dynamic interplay of multiple cognitive processes, from basic sound perception, to linguistic encoding, and finally to complex semantic-conceptual interpretations. How the brain handles the diverse streams of information processing remains poorly understood. Applying Hidden Markov Modeling to fMRI data obtained during spoken narrative comprehension, we reveal that the whole brain networks predominantly oscillate within a tripartite latent state space.

Background: Heart failure, a complex clinical syndrome with high morbidity and mortality, has become a significant burden on public health. Recently, a new class of antidiabetic agents-the sodium-glucose cotransporter 2 (SGLT2) inhibitors-was associated with a significant reduction on mortality and hospitalization in HF with reduced ejection fraction (HFrEF) when added to standard pharmacological treatment. Considering the lack of data on its cost-effectiveness, the present study aims to estimate the incremental cost-effectiveness ratio of add-on dapagliflozin treatment for HFrEF from the Brazilian public healthcare system perspective.

Objectives: This study evaluated the cost-effectiveness of using hearing aids among individuals aged 50 and older with varying levels of hearing loss in South Korea.
Methods: A state-transition Markov model was employed to assess the cost-effectiveness of hearing aid utilization from a societal perspective. We simulated a cohort of patients aged 50, tracking their progression through normal, mild, moderate, and severe stages of hearing loss until death or age 80.

This study evaluates the cost-effectiveness of adding durvalumab to chemotherapy, with subsequent maintenance either with olaparib (DOCT) or without olaparib (DCT), versus chemotherapy alone (CT) as a first-line treatment for advanced endometrial cancer (EC) in the United States, stratified by mismatch repair deficiency (dMMR) and proficiency (pMMR). A Markov model based on DUO-E Phase III trial data simulated disease progression and outcomes. Total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICER) were evaluated.
