A review on Thermodynamics in Water Cycle with Emphasizing on Entropy and Maximum Entropy Production Principle [PDF]

open access: yesعلوم و مهندسی آب و فاضلاب, 2022
Hydrological cycle is directed into thermodynamic non-equilibrium state and maximum entropy production through thermodynamic processes. Therefore, it is possible to understand and describe hydrological cycle through computation of entropy production rate

The Eco-Evo Mandala: Simplifying Bacterioplankton Complexity into Ecohealth Signatures

open access: yesEntropy, 2021
The microbiome emits informative signals of biological organization and environmental pressure that aid ecosystem monitoring and prediction. Are the many signals reducible to a habitat-specific portfolio that characterizes ecosystem health?

Optimal Investment and Consumption for Multidimensional Spread Financial Markets with Logarithmic Utility

open access: yesStats, 2021
We consider a spread financial market defined by the multidimensional Ornstein–Uhlenbeck (OU) process. We study the optimal consumption/investment problem for logarithmic utility functions using a stochastic dynamical programming method.

Production inventory models for deteiorative items with three levels of production and shortages [PDF]

open access: yesYugoslav Journal of Operations Research, 2017
In this paper, three level production inventory models for deteriorative items are considered under the variation in production rate. Namely, it is possible that production started at one rate, after some time, switches to another rate.

Optimal policy for attention-modulated decisions explains human fixation behavior

open access: yeseLife, 2021
Traditional accumulation-to-bound decision-making models assume that all choice options are processed with equal attention. In real life decisions, however, humans alternate their visual fixation between individual items to efficiently gather relevant ...

Optimism [PDF]

open access: yesClinical Psychology Review, 2010
Optimism is an individual difference variable that reflects the extent to which people hold generalized favorable expectancies for their future. Higher levels of optimism have been related prospectively to better subjective well-being in times of adversity or difficulty (i.e., controlling for previous well-being).
