Application and performance of a Low Power Wide Area Sensor Network for distributed remote hydrological measurements.

Communication distances of wireless sensor networks (WSNs) are greatly limited in settings where vegetation coverage is moderate or dense, and power consumption can be an issue in remote environmental settings. A newer innovative technology called "Low Power Wide Area Sensor Networks" (LPWAN) is capable of greater communication distances while consuming less power than traditional WSNs. This research evaluates the design and in-field performance of a LPWAN configuration in headwater catchments to measure environmental variables.

Oncologic long-term outcome of single-incision laparoscopic surgery (SILS) for colorectal cancer.

Purpose: Single-incision laparoscopic surgery (SILS) has been introduced as a less invasive alternative to multi-port laparoscopic surgery (MLS). MLS is widely accepted for the treatment of colorectal cancer, but there remains minimal evidence for the use of SILS. Thus, we compared both short- and long-term outcomes of SILS and open surgery (OS) in matched cohorts of colorectal cancer patients.
