On some stochastic mirror descent methods for constrained online optimization problems [PDF]
Компьютерные исследования и моделирование, 2019 The problem of online convex optimization naturally occurs in cases when there is an update of statistical information. The mirror descent method is well known for non-smooth optimization problems. Mirror descent is an extension of the subgradient method

Stochastic Satisfiability Modulo Theories for Non-linear Arithmetic [PDF]
, 2008 The stochastic satisfiability modulo theories (SSMT) problem is a generalization of the SMT problem on existential and randomized (aka. stochastic) quantification over discrete variables of an SMT formula. This extension permits the concise description of diverse problems combining reasoning under uncertainty with data dependencies.

Business Strategy and the Environment, EarlyView.ABSTRACT Policy intervention can be a driver for industrial symbiosis (IS). However, given the wide variety of policy instruments available, policymakers should be guided in the policy design process to ensure that their intervention is effective and efficient. In this paper, we propose an agent‐based (AB) model intended to assess the effectiveness and

Heat Load Mitigation Studies in the W7‐X Stellarator Experiment
Contributions to Plasma Physics, EarlyView.ABSTRACT During the experiments at the stellarator Wendelstein 7‐X (W7‐X) with fully water‐cooled plasma‐facing components (PFC), including carbon‐fiber composite (CFC) divertor targets with a thermal load capability of 10 MW/m2, high performance was achieved.

‘biomod2' – extending presence–absence species distribution models to multiple data types
Ecography, EarlyView.The R package ‘biomod2' is one of the most widely used and versatile tools for species distribution modelling (SDM), enabling ecologists to calibrate, evaluate, and project species–environment relationships across space and time using multiple modelling algorithms and ensemble forecasting.

Quasilinear Structures in Stochastic Arithmetic and their Application
Serdica Journal of Computing, 2017 Stochastic arithmetic has been developed as a model for computing with imprecise numbers. In this model, numbers are representedby independent Gaussian variables with known mean value and standarddeviation and are called stochastic numbers. The algebraic properties of stochastic numbers have already been studied byseveral authors.

Epilepsia, EarlyView.Abstract Objective A multi‐electrode array (MEA) is a powerful extracellular recording technique for long‐term monitoring of neuronal network activity. In recent years, MEA‐based assays have been applied increasingly to evaluate drug efficacy and neurotoxicity, including the assessment of anti‐seizure medications (ASMs). However, systematic comparisons

Journal of Modern Power Systems and Clean Energy, 2018 Optimal power flow (OPF) has been used for energy dispatching in active distribution networks. To satisfy constraints fully and achieve strict operational bounds under the uncertainties from loads and sources, this paper derives an interval optimal power
