Understanding the spatiotemporal distribution of people within a city is crucial to many planning applications. Obtaining data to create required knowledge, currently involves costly survey methods. At the same time ubiquitous mobile sensors from personal GPS devices to mobile phones are collecting massive amounts of data on urban systems. The locations, communications, and activities of millions of people are recorded and stored by new information technologies. This work utilizes novel dynamic data, generated by mobile phone users, to measure spatiotemporal changes in population. In the process, we identify the relationship between land use and dynamic population over the course of a typical week. A machine learning classification algorithm is used to identify clusters of locations with similar zoned uses and mobile phone activity patterns. It is shown that the mobile phone data is capable of delivering useful information on actual land use that supplements zoning regulations.

Massive and passive data such as cell phone traces provide samples of the whereabouts and movements of individuals. These are a potential source of information for models of daily activities in a city. The main challenge is that phone traces have low spatial precision and are sparsely sampled in time, which requires a precise set of techniques for mining hidden valuable information they contain. Here we propose a method to reveal activity patterns that emerge from cell phone data by analyzing relational signatures of activity time, duration, and land use. First, we present a method of how to detect stays and extract a robust set of geolocated time stamps that represent trip chains. Second, we show how to cluster activities by combining the detected trip chains with land use data. This is accomplished by modeling the dependencies between activity type, trip scheduling, and land use types via a Relational Markov Network. We apply the method to two different kinds of mobile phone datasets from the metropolitan areas of Vienna, Austria and Boston, USA. The former data includes information from mobility management signals, while the latter are usual Call Detail Records. The resulting trip sequence patterns and activity scheduling from both datasets agree well with their respective city surveys, and we show that the inferred activity clusters are stable across different days and both cities. This method to infer activity patterns from cell phone data allows us to use these as a novel and cheaper data source for activity-based modeling and travel behavior studies.

Hormonal cancers affect over 400,000 men and women and contribute collectively to over 100,000 deaths in the United States alone. Thanks to advances in the understanding of these cancers at the molecular level and to the discovery of several disease-modifying therapeutics, the last decade has seen a plateauing or even a decreasing trend in the number of deaths from these cancers. These advanced therapeutics not only effectively slow the growth of hormonal cancers, but also provide an insight on how these cancers become refractory and evolve as an altogether distinct subset. This review summarizes the current therapeutic trends in hormonal cancers, with focus on prostate, breast and ovarian cancers. The review discusses the clinical drugs being used now, promising molecules that are going through various stages of development and makes some predictions on how the therapeutic landscape will shift in the next decade.

Objective To assess the rate and risk factors for position-related injury in robotic gynecologic surgery. Methods A prospective database from 12/2006 to 1/2014 of all planned robotic gynecologic procedures was retrospectively reviewed for patients who experienced neurologic injury, musculoskeletal injury, or vascular compromise related to patient positioning in the operating room. Analysis was performed to determine risk-factors and incidence for position-related injury. Results Of the 831 patients who underwent robotic surgery during the study time period, only 7(0.8%) experienced positioning-related injury. The injuries included minor head contusions (n=3), two lower extremity neuropathies (n=2), brachial plexus injury (n=1) and one large subcutaneous ecchymosis on the left flank and thigh (n=1). There were no long term sequelae from the positioning-related injuries. The only statistically significant risk factor for positioning-related injury was prior abdominal surgery (p = 0.05). There were no significant associations between position-related injuries and operative time (P = 0.232), body mass index (P=0.847), age (p = 0.152), smoking history (P = 0.161), or medical comorbidities (P = 0.229 – 0.999). Conclusions The incidence of position-related injury among women undergoing robotic surgery was extremely low (0.8%). Due to the low incidence we were unable to identify modifiable risk factors for position-related injury following robotic surgery. A standardized, team-oriented approach may significantly decrease position-related injuries following robotic gynecologic surgery.
