Introduction: Primary polydipsia, frequently observed in patients with schizophrenia, can cause severe hyponatremia, leading to serious complications. Objective: This study reviews the management and prevalence of psychogenic polydipsia, focusing on treatments and clinical outcomes. Methods: Following the PRISMA guidelines, studies on polydipsia in psychiatric patients were included. data were extracted from databases such as PubMed and Scopus, and a meta-analysis was performed. Results: Fifteen studies were analyzed, totaling 586 patients. The use of urea was effective in correcting hyponatremia, while antipsychotics showed mixed results. Heterogeneity between studies was moderate (I2 = 56%). Conclusion: Psychogenic polydipsia is a severe condition in schizophrenic patients. The use of urea has shown promise, but further studies are needed to optimize treatments.

In this paper the authors consider the operational problem of optimal signalling and control,called control-coding capacity(with feedback), CF b in bits/second, of discrete-time nonlinear partially observable stochastic systems in state space form, subject to an average cost constraint. CF b is the maximum rate of encoding signals or messages into randomized controller-encoder strategies with feedback, which control the state of the system, and reproducing the messages at the output of the system using a decoder or estimator with arbitrary small asymptotic error probability. In the first part of the paper, the authors characterize CF b by an information theoretic optimization problem of maximizing directed information from the inputs to the outputs of the system, over randomized strategies(controller-encoders). The authors derive equivalent characterizations of CF b, using randomized strategies generated by either uniform or arbitrary distributed random variables(Rvs), sufficient statistics,and a posteriori distributions of nonlinear filtering theory. In the second part of the paper, the authors analyze CF b for linear-quadratic Gaussian partially observable stochastic systems(LQG-POSSs). The authors show that randomized strategies consist of control, estimation and signalling parts, and the sufficient statistics are, two Kalman-filters and an orthogonal innovations process. The authors prove a semi-separation principle which states, the optimal control strategy is determined explicitly from the solution of a control matrix difference Riccati equation(dRE), independently of the estimation and signalling strategies. Finally, the authors express the optimization problem of CF b in terms of two filtering matrix dREs, a control matrix dRE, and the covariance of the innovations process. Throughout the paper, the authors illustrate that the expression of CF b includes as degenerate cases, problems of stochastic optimal control and channel capacity of information transmiss

Organic solar cells(OSCs) hold great potential as a photovoltaic technology for practical ***, the traditional experimental trial-and-error method for designing and engineering OSCs can be complex, expensive, and time-consuming. Machine learning(ML) techniques enable the proficient extraction of information from datasets, allowing the development of realistic models that are capable of predicting the efficacy of materials with commendable accuracy. The PM6 donor has great potential for high-performance OSCs. However, it is crucial for the rational design of a ternary blend to accurately forecast the power conversion efficiency(PCE) of ternary OSCs(TOSCs) based on a PM6 ***, we collected the device parameters of PM6-based TOSCs and evaluated the feature importance of their molecule descriptors to develop predictive models. In this study, we used five different ML algorithms for analysis and prediction. For the analysis, the classification and regression tree provided different rules, heuristics, and patterns from the heterogeneous dataset. The random forest algorithm outperforms other prediction ML algorithms in predicting the output performance of PM6-based TOSCs. Finally, we validated the ML outcomes by fabricating PM6-based TOSCs. Our study presents a rapid strategy for assessing a high PCE while elucidating the substantial influence of diverse descriptors.
