Abstract Contact tracing plays a crucial role in identifying exposed individuals at high risk of infection during disease outbreaks. In this paper, we propose fuzzy logic-based contact model for predicting high-risk The utilizes various input parameters, including distance, overlap time, visiting time lag, incubation and facility size, to assess the infection. Through application logic, enables modeling complex relationships uncertainties associated with these parameters. We evaluated using simulated data, demonstrating its effectiveness different levels risk. evaluation includes partial evaluation, comprehensive inputs assessment impact each parameter on results highlight importance considering multiple factors provide insights into key parameters that significantly influence assessment. proposed has potential assist public health authorities making informed decisions implementing targeted interventions mitigate spread diseases outbreak situations. Moreover, it helps alleviate unnecessary fear among who are less likely have been infected.

The role of estuaries in sourcing and transforming dissolved organic matter - the largest reservoir carbon ocean still presents many unknowns for coastal biogeochemical cycles, is further complicated by increasing human pressures a changing climate. Here, we examined major drivers colored (CDOM) dynamics Long Island Sound (LIS), heavily urbanized estuary National Significance with storied water quality past. A comprehensive new optical dataset, including measurements CDOM absorption fluorescence signatures, was integrated biological hydrological to capture spatiotemporal heterogeneities LIS, its urban-to-rural gradient, dynamic river mouths, blue ecosystems across seasons, following episodic storm events, over five years.

Abstract Dissolved organic matter and its colored component, Colored Organic Matter (CDOM), play a major role in global carbon budgets, their fluxes provide an essential link between terrestrial aquatic biogeochemical cycles. Satellite observations can uniquely capture the hydro‐biogeochemical connectivity of landscapes, across scales. Yet, accurate satellite retrievals CDOM dissolved (DOC) dynamics remain challenging urbanized estuaries coasts. Here, we present advanced unified algorithm for space‐based retrieval coastal DOC application Long Island Sound—one world's most heavily that is becoming increasingly vulnerable to climate change stressors. A rich bio‐optical data set, encompassing wide range environmental conditions, was integrated into training retrieve concentrations spectral shape (i.e., slope S 275–295 )—a proxy quality. The new algorithms were applied full‐resolution imagery from Sentinel‐3 Ocean Land Color Instrument (OLCI) after thoroughly evaluating performance six ocean color atmospheric correction approaches (ACOLITE, BAC, C2RCC, MUMM, l2gen , Polymer). Evaluation yielded mean absolute percent differences 28%, 12%, 10% (300), DOC, respectively. Application multi‐year OLCI captured, first time, coupled impact seasonal transitions, wind regimes, freshwater inputs, anthropogenic disturbances, hydrological extremes (both intense precipitation droughts) on quality at ecosystem scale. Results have important implications improved predictions complex urban−estuary systems.

Abstract The COVID‐19 pandemic has led to significant societal disruptions, prompting the Indonesian government implement various measures, including partial lockdowns or Community Activities Restrictions Enforcement (CARE), curb virus's spread. This research aims assess impact of environmental parameters on Cirebon's estuaries, focusing physical components (such as temperature, total solids [TS], and turbidity), chemical (including pH, biochemical oxygen demand (BOD), dissolved (DO), nitrate, phosphate), microbiology (specifically coliforms). These comprehensive have notably impacted during pre‐, during, post‐COVID‐19 based Water Quality Index (WQI) assessment in estuaries. In port city Cirebon, located Java Island's northern coast, water quality three river estuaries Kesenden, Sukalila, Kalijaga was analyzed before after CARE implementation. samples collected 2019, 2020, 2022, 2023 were evaluated against Class II standards per Government Regulation No. 22 2021. WQI determined using National Sanitation Foundation (NSF‐WQI) technique revealing fluctuations trends across stations over 2019–2023. at recorded 52.21, 56.40, 53.36, respectively. By began COVID 19, there a noticeable decreasing WQI, Sukalila sustained “Moderate” classification with 54.59, whereas Kesenden witnessed declines values 49.5 49.7, However, peak‐implementation program 2022 saw drastic decline quality, dropping below threshold all observed stations, 23.97 23.10 35.36 Kalijaga. Meanwhile, experienced increasing (remained poor category) index 44.31, 35.14, 42.0 Kalijaga, findings underscore complex interplay between human activities health, highlighting need for sustainable practices robust management policies mitigate adverse effects such disruptions. results from monitoring ocean health pre‐ post‐the implementation era provided unique opportunity reflect behavior its environment, emphasizing importance adopting pro‐environmental behaviors support development post‐pandemic era.
