Leaf area index (LAI) is an important parameter in plant ecophysiology; it can be used to quantify foliage directly and as a measure of the photosynthetic active and, thus, subject transpiration vegetation. The aim this paper was review work on remote sensing methods estimating LAI across different forest ecosystems, crops grasslands terms platforms, sensors models. To achieve aim, scholarly ar...

Marine bird at-sea distributions are surveyed using two standardized population surveying techniques: line transects and strip transects (Buckland et al. 1993). Line transects use the perpendicular distances to individual sightings to model a detection function, which quantifies the probability of observing an object given its distance from the trackline. This approach allows for speciesspecifi...

Right-hemisphere patients with left neglect often demonstrate abnormal visual search, re-examining stimuli to the right while ignoring those to the left. But re-fixations alone do not reveal if patients misjudge whether they have searched a location before. Here, we not only tracked the eye movements of 16 neglect patients during search, but also asked them to click a response button only when ...

Methods Search Strategy We searched the Cochrane Stroke Group Trials Register (last searched June 2003). In addition, the following electronic databases were searched: Cochrane Central Register of Controlled Trials (Cochrane Library, Issue 4, 2002), MEDLINE (1966 to December 2002), EMBASE (1980 to December 2002), CINAHL (1982 to December 2002), SPORTDiscus (1949 to December 2002), Science Citat...

Pigeons and humans searched for a goal that was hidden in varied locations within a search space. The goal location was fixed relative to an array of identical landmarks. Pigeons searched on the laboratory floor, and humans searched on a table top or an outdoor field. In Experiment 1, the goal was centered in a square array of 4 landmarks. When the spacing between landmarks was increased, human...

Obesity is a global epidemic with major healthcare implications and costs. Mobile technologies are potential interventions to promote weight loss. An early systematic review of this rapidly growing area of research was conducted. Electronic databases were searched for articles published between January 1998 and October 2011. Data sources included Medline, Embase and the Cochrane Central Registe...

OBJECTIVE To assess the anti-caries effect of arginine-containing formulations in vivo on caries lesions compared with fluorides or placebo. METHODS Randomized or quasi-randomized human clinical trials wherein arginine was delivered by any method were considered. The MEDLINE, Web of Science, EMBASE, Cochrane Library, and CBM databases were searched to identify relevant articles published up t...

Background and aims: Health technology assessments (HTA’s) have been known as a scientific approach for improving of patient outcomes also efficacy promoting of health systems. Therefore, in this study, scientific publications of HTAs in PubMed have been assessed. Methods: In this descriptive-scientometrics research, all HTA studies were searched in PubMed in August 2016. For this purpose, spec...

We focus on the problem of finding the best search set for expanding ring search (ERS) in wireless networks. ERS is widely used to locate randomly selected destinations or information in wireless networks such as wireless sensor networks In ERS, controlled flooding is employed to search for the destinations in a region limited by a time-to-live (TTL) before the searched region is expanded. The ...

Epigenetics, and more specifically DNA methylation is a fast evolving research area. In almost every cancer type, each month new publications confirm the differentiated regulation of specific genes due to methylation and mention the discovery of novel methylation markers. Therefore, it would be extremely useful to have an annotated, reviewed, sorted and summarized overview of all available data...
