Published: March 2022

Abstract. In mangrove forests, soil salinity is one of the most significant environmental factors determining forest distribution and productivity as it
limits plant water uptake and carbon gain. However, salinity control on mangrove productivity through plant hydraulics has not been investigated by
existing mangrove models. Here we present a new individual-based model linked with plant hydraulics to incorporate physiological characterization of
mangrove growth under salt stress. Plant hydraulics was associated with mangroves' nutrient uptake and biomass allocation apart from water flux and
carbon gain. The developed model was performed for two coexisting species – Rhizophora stylosa and Bruguiera gymnorrhiza – in a
subtropical mangrove forest in Japan. The model predicted that the productivity of both species was affected by soil salinity through downregulation
of stomatal conductance. Under low-soil-salinity conditions (< 28 ‰), B. gymnorrhiza trees grew faster and suppressed the
growth of R. stylosa trees by shading that resulted in a B. gymnorrhiza-dominated forest. As soil salinity increased, the
productivity of B. gymnorrhiza was significantly reduced compared to R. stylosa, which led to an increase in biomass of
R. stylosa despite the enhanced salt stress (> 30 ‰). These predicted patterns in forest structures across the soil salinity
gradient remarkably agreed with field data, highlighting the control of salinity on productivity and tree competition as factors that shape the
mangrove forest structures. The model reproducibility of forest structures was also supported by the predicted self-thinning processes, which
likewise agreed with field data. Aside from soil salinity, seasonal dynamics in atmospheric variables (solar radiation and temperature) were
highlighted as factors that influence mangrove productivity in a subtropical region. This physiological principle-based improved model has the
potential to be extended to other mangrove forests in various environmental settings, thus contributing to a better understanding of mangrove
dynamics under future global climate change.
Fast yaw optimization for wind plant wake steering using Boolean yaw angles
Authors: Stanley Andrew P. J. , Bay Christopher , Mudafort Rafael , Fleming Paul 
Published: March 2022

Abstract. In wind plants, turbines can be yawed into the wind to steer their wakes away from downstream turbines and achieve an overall increase in plant power. Mathematical optimization is typically used to determine the best yaw angles at which to operate the turbines in a plant. In this paper, we present a new heuristic to rapidly determine the yaw angles in a wind plant. In this method, we define the turbine yaw angles as Boolean – either yawed at a predefined angle or nonyawed – as opposed to the typical methods of defining yaw angles as continuous or with fine discretizations. We then optimize which turbines should be yawed with an algorithm that sweeps through the turbines from the most upstream to the most downstream. We demonstrate that our new Boolean optimization method can find turbine yaw angles that perform well compared to a traditionally used gradient-based optimizer for which the yaw angles are defined as continuous. There is less than 0.6 % difference in the optimized power between the two optimization methods for randomly placed turbine layouts and less than a 0.6 % difference in the optimal annual energy production between the two optimization methods for a real wind farm. Additionally, we show that our new method is much more computationally efficient than the traditional method. For plants with nonzero optimal yaw angles, our new method is generally able to solve for the turbine yaw angles 50–150 times faster, and in some extreme cases up to 500 times faster, than the traditional method.

Objective To determine the difference in the total number of COVID-19 cases and deaths between Muslim-majority and non-Muslim countries, and investigate reasons for anydisparities. Methods A cross-country panel analysis of the total number of new COVID-19 cases per million for 165 countries was conducted from May 1, 2020 to July 1, 2021. Regression models of the total number of COVID-19 cases and deaths per million were created for the 3 global peak dates of July 31, 2020 and January 7 and April 29, 2021. Results The number of daily new COVID-19 cases per million was signficantly less in Muslim-majority countries (N = 49) than non-Muslim countries (N=116), SD 1.57E-1, p-value <0.001 from May 1, 2020 to July 1, 2021. Total number of cases per million of Muslim-majority countries was significantly less on July 31st: 0.089, p-value <0.001; January 7th: SD 0.012, p-value 0.04; April 29th: SD 0.009, p-value <0.01. Total number of deaths per million of Muslim-majority countries was also significantly less on July 31st: 0.510, p-value 0.009; January 7th: SD 0.090, p-value <0.001; April 29th: SD 0.065, p-value 0.03. Discussion The data suggests a relationship between Islamic practices and the incidence of COVID-19 and COVID-19 related deaths. This study explored how that Muslims’ practice of tahara (purity or cleanliness) is similar to many COVID-19 containment measures and tawakkul (trust in Allah) helps them remain resilient and hopeful during difficult unpredictable times, such as living through a pandemic. Conclusion It is hoped that this paper brings awareness to the positive practices of the Islamic faith as it relates to COVID-19, and to population and individual health. Research should be conducted with Muslims in Muslim-majority and non-Muslim countries to further study the relationship between Islam and health.
