Treatment of urinary incontinence after total hysterectomy with acupuncture: A case report.

Rationale: Acupuncture is a significant feature of traditional Chinese medicine, which can dredge the channels, harmonize qi and blood, replenish deficiency and relieve excess, strengthen the body and remove pathogens to treat urinary incontinence after hysterectomy, and improve the quality of life, which is simple, convenient, inexpensive, and practical.

Patient Concerns: After a total hysterectomy, the catheter was retained every day, causing urinary incontinence and elderly urine wetness for 30 days.

Diagnoses: Postoperative urinary incontinence for 1 month; type 2 diabetes for 4 years.

Effects of urban microcellular environments on ray-tracing-based coverage predictions.

The ray-tracing (RT) algorithm, which is based on geometrical optics and the uniform theory of diffraction, has become a typical deterministic approach of studying wave-propagation characteristics. Under urban microcellular environments, the RT method highly depends on detailed environmental information. The aim of this paper is to provide help in selecting the appropriate level of accuracy required in building databases to achieve good tradeoffs between database costs and prediction accuracy.
