چکیده
In 1937, Stone [6] introduced and investigated the regular open sets. These sets are contained in the family of open sets since a set is regular open if it is equal to the interior of its closure. In 1978, Cameron [2] also introduced and investigated the concept of a regular semiopen set. A set A is regular semiopen if there is a regular open set U such that U ⊆ A ⊆ U . In 2007, a new class of sets called regular w-closed sets (rw-closed sets) was introduced by Benchalli and Wali [1]. A set B is rw-closed if B ⊆ U whenever B ⊆ U for any regular semiopen set U . They proved that this new class of sets is properly placed

Fuzzy rw-Connectedness and Fuzzy rw-Disconnectedness in Fuzzy Topological Spaces
In this paper, using the concept of fuzzy rw-open set we shall define various notions of fuzzy rw-connectedness and fuzzy rw-disconnectedness in fuzzy topological spaces and some of their properties and characterizations of such spaces are also investigated.
متن کاملRelaxed Wasserstein with Applications to GANs
We propose a novel class of statistical divergences called Relaxed Wasserstein (RW) divergence. RW divergence generalizes Wasserstein distance and is parametrized by strictly convex, differentiable functions. We establish for RW several key probabilistic properties, which are critical for the success of Wasserstein distances. In particular, we show that RW is dominated by Total Variation (TV) a...
متن کاملA Novel Side-Chain Orientation Dependent Potential Derived from Random-Walk Reference State for Protein Fold Selection and Structure Prediction
BACKGROUND An accurate potential function is essential to attack protein folding and structure prediction problems. The key to developing efficient knowledge-based potential functions is to design reference states that can appropriately counteract generic interactions. The reference states of many knowledge-based distance-dependent atomic potential functions were derived from non-interacting pa...
متن کاملThe Therapeutic Effect of Exercise on Anxiety and Bowel Oxidative Stress in the Maternal Separation Animal Model
Introduction: According to evidence, Early-Life Stress (ELS), mood disorders, and medical comorbidities, i.e. Irritable Bowel Syndrome (IBS), are correlated; however, the direct contribution of ELS to IBS manifestations is less understood. The current study aimed at evaluating the effect of voluntary exercise on the mitochondrial dysfunction of the bowel fibroblasts, following the confirmation...
متن کاملA Hilbert Space Approach to Effective Resistance Metric
A resistance network is a connected graph (G, c). The conductance function cxy weights the edges, which are then interpreted as conductors of possibly varying strengths. The Dirichlet energy form E produces a Hilbert space structure (which we call the energy space HE) on the space of functions of finite energy. We use the reproducing kernel {vx} constructed in [JP09b] to analyze the effective r...
