Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, EarlyView.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Trigonometric words ranking model for spam message classification

IET Networks, EarlyView., 2022
Abstract The significant increase in the volume of fake (spam) messages has led to an urgent need to develop and implement a robust anti‐spam method. Several of the current anti‐spam systems depend mainly on the word order of the message in determining the spam message, which results in the system's inability to predict the correct type of message when

Dose‐dependent association of systemic comorbidities with periodontitis severity: A large population cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background To examine whether the associations between periodontitis and multiple systemic conditions increase with increasing severity of periodontitis using a multi‐center electronic health record (EHR) repository. Methods A cross‐sectional analysis was conducted using EHR data from 9 dental schools in the United States.

Evaluating the impact of hunter access and harvest regulations on elk movement and resource selection

The Journal of Wildlife Management, EarlyView.
We estimated daily probabilities of female elk transitioning between hunter access strategies during 4 periods of the fall hunting season in the Devil's Kitchen study area in central Montana, USA, 2020‐2023. Elk generally avoided harvest risk by selecting for less hunter access and more restrictive harvest regulations.

Polynomial Characterizations of Distance‐Biregular Graphs

Journal of Graph Theory
ABSTRACTFiol, Garriga, and Yebra introduced the notion of pseudo‐distance‐regular vertices, which they used to come up with a new characterization of distance‐regular graphs. Building on that work, Fiol and Garriga developed the spectral excess theorem for distance‐regular graphs.

A low‐cost, automated, and adaptable system for field‐based measurement of pCO2, pCH4, and associated variables in groundwater

Limnology and Oceanography: Methods, EarlyView.
Abstract The Groundwater Automated Chemical Examiner (GrACE) is an automated analytical system of integrated sensors for the field‐based measurement of chemical and physical properties of groundwater. The GrACE system was designed to explore parameters influencing the dissolved concentrations of carbon dioxide (pCO2) and methane (pCH4) in groundwater ...
