However, the specific sharing features of the FFBS can also be a problem for users because randomly scattered and faulty bikes within the system can result in bike unavailability and maintenance difficulties. This not only negatively impacts the company’s service quality but also causes user safety issues. In this study, a mechanism for the rebalancing of useable bikes and faulty bikes is presented in two steps: 1) gathering each faulty bike at a station determined by the model traversing the shortest path by light service vehicles; and 2) enabling the rebalancing operation to obtain optimal bike inventory levels at all stations and collect faulty bikes at a depot. The destination station from which each faulty bike is taken is considered a decision variable rather than shifting them to a closer station. The mechanism is b...

SBEM is the development of a spontaneous infectious process in a pre-existing pleural effusion without any evidence of pneumonia in patients with Hepatic Hydrothorax. Patients with SBEM has poor prognosis with significantly high rate of mortality and morbidity. We present the case of a 54-year-old female with history of decompensated liver cirrhosis secondary to alcohol use disorder, recurrent ascites, refractory bilateral pleural effusions who had developed SBEM associated with uncharacteristically high glycopleuria values. In this article, we will emphasize on recent data focusing on the diagnostic complications and treatment of cirrhotic patients with SBEM. Increased awareness of this uncommon condition will help clinicians recognize and address it early.

However, the major problem of the conventional substitution boxes is the statistic behavior, which is employed as a fixed-size lookup table. To solve the fixed-size lookup table problem, various substitution box construction methods were proposed with key control, but it is hard to enhance all cryptographic properties, for example, linear and differential probabilities. Thus, chaos is applied for key control in designing robust substitution boxes due to unpredictable and random-like behavior. Moreover, the confusion and diffusion properties of cryptography can be achieved by chaos. This article introduces an efficient construction of a key-dependent substitution box based on the mixing property of the chaotic sine map. The substitution box so constructed has very low differential and linear approximation probabilities. The experimental results confirmed that the proposed method to construct substitution ...
