"Estimating soil surface roughness by proximal sensing for soil erosion modeling implementation at field scale".

Soil Surface Roughness (SSR) is a physical feature of soil microtopography, which is strongly influenced by tillage practices and plays a key role in hydrological and soil erosion processes. Therefore, surface roughness indices are required when using models to estimate soil erosion rates, where tabular values or direct measurements can be used. Field measurements often imply out-of-date and time-consuming methods, such as the pin meter and the roller chain, providing inaccurate indices.

A Factor-Graph-Based Approach to Vehicle Sideslip Angle Estimation.

Sideslip angle is an important variable for understanding and monitoring vehicle dynamics, but there is currently no inexpensive method for its direct measurement. Therefore, it is typically estimated from proprioceptive sensors onboard using filtering methods from the family of the Kalman filter. As a novel alternative, this work proposes modeling the problem directly as a graphical model (factor graph), which can then be optimized using a variety of methods, such as whole-dataset batch optimization for offline processing or fixed-lag smoothing for on-line operation.

Totally laparoscopic repair of an ileal and uterine iatrogenic perforation secondary to endometrial curettage.

Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage.

Retroperitoneal sarcoma involving unilateral double ureter: management, treatment and psychological implications.

The case of a 45-year-old woman who was admitted to our university hospital for polymenorrhea, weight gain and pain in the left iliac region is reported. An abdominal ultrasound revealed a 9.5 × 5.
