The Performance Investigation of Smart Diagnosis for Bearings Using Mixed Chaotic Features with Fractional Order.

This article presents a performance investigation of a fault detection approach for bearings using different chaotic features with fractional order, where the five different chaotic features and three combinations are clearly described, and the detection achievement is organized. In the architecture of the method, a fractional order chaotic system is first applied to produce a chaotic map of the original vibration signal in the chaotic domain, where small changes in the signal with different bearing statuses might be present; then, a 3D feature map can be obtained. Second, five different features, combination methods, and corresponding extraction functions are introduced.

[The Relationship Between Coping Behaviors and Symptom Distress in Elderly Patients With Cancer Undergoing Initial Chemotherapy].

Background: Elderly cancer patients undergoing initial chemotherapy often suffer discomfort from medication-related symptom distress. This discomfort may affect treatment responses and outcomes negatively.

Purpose: This correlational, cross-sectional design study used a purposive sample of 100 patients who were both over 60 years of age and currently undergoing initial chemotherapy.

Effects of insulin replacement on cardiac apoptotic and survival pathways in streptozotocin-induced diabetic rats.

Increased myocyte apoptosis in diabetic hearts has been previously reported. Therefore, the purpose of this study was to evaluate the effects of insulin on cardiac apoptotic, hypertrophic, and survival pathways in streptozotocin (STZ)-induced diabetic rats. Forty-eight male Wistar rats at 8 weeks of age were randomly divided into control group (Control), STZ-induced (65 mg/kg STZ i.

Beneficial effects of taurine on cardiac abnormality in NZB/W F1 mice fed with a high-cholesterol diet.

A significantly higher prevalence of cardiovascular disease (CVD) is reported in patients with systemic lupus erythematosus (SLE) as compared with the general population and accounts for approximately 30% of deaths in SLE patients. However, the mechanism of and treatments for CVD in patients with SLE are still unclear. To explore the effects of taurine on cardiac abnormality in SLE, NZB/W F1 mice were used as the experimental model by receiving control, cholesterol, or cholesterol/taurine diets, respectively.

Vegetation on patent foramen ovale presenting as a cryptogenic brain abscess.

This paper describes a case of 51-year-old man with a vegetation on his patent foramen ovale presenting with a cryptogenic brain abscess. He received surgical evacuation and was successfully managed with septal occlusion. This is the first reported case of cryptogenic brain abscess caused by a vegetation on a patent foramen ovale directly documented with transesophageal echocardiography.
