rangelands have been composed of different plant species that emergence of phenological stages in every one of them will be influenced by environmental and genetic factors. in order to exploit the time and achieve acceptable performance in each plant species, it is necessary that the emergence of biological phenomena are recorded and studied. the objective of the present study is to survey the ...

This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in real-time in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The...

Thirty-four months (2017–2020) of mooring data were recently obtained at 80.6°N, 7.26°E in the main branch Atlantic Water inflow to Arctic, Yermak Pass Branch. The Branch was sampled that same location during 14 a decade ago (2007–2008) when sea ice abundant (mean sea-ice concentration 74% vs. 39% recent deployment). We focus on time scales larger than 50 hr. new set shows an increase velocity ...

OBJECTIVE Primary liver cancer (PLC) is a serious disease with high mortality. During the last decade, improvements in the diagnostic procedures and treatment of PLC may have improved survival. However, few updated longitudinal studies examined this issue. In a population-based setting, we studied changes in the prognoses over time. METHODS Between 1998 and 2009, we identified all patients wi...

We retrospectively calculated the prevalence and epidemiologic characteristics of Chagas infection in the New York blood donor population over three years utilizing the New York Blood Center's database of the New York metropolitan area donor population. Seventy Trypanosoma cruzi positive donors were identified from among 876,614 donors over a 3-year period, giving an adjusted prevalence of 0.00...

BACKGROUND AND PURPOSE Over the past 20 years, several changes in treatment policy and treatment options have taken place regarding hip replacement. For this reason, we wanted to investigate the results after hip replacement in terms of revision rate, during a 21-year period among hip replacements reported to the Norwegian Arthroplasty Register. METHODS 110,882 primary total hip replacements ...

This report presents a brief summary of papers describing physical oceanographic research undertaken in Canada in the period 2003 to early 2007. This report is part of the Canadian contribution to the International Association for the Physical Sciences of the Ocean (IAPSO) on the occasion of the meeting of the Interannual Association of Geodesy and Geophysics (IUGG) in Perugia, Italy in July 20...

BACKGROUND Concussion in the National Football League (NFL) remains an important issue. An initial description of the injury epidemiology involved 6 years from 1996 to 2001. HYPOTHESIS The increased attention to concussions may have resulted in team physicians being more conservative in treating players in recent years. STUDY DESIGN Two consecutive 6-year periods (1996-2001 and 2002-2007) w...
