Ensembles of wrappers for automated feature selection in fish age classification [PDF]
, 2017 In feature selection, the most important features must be chosen so as to decrease the number thereof while retaining their discriminatory information. Within this context, a novel feature selection method based on an ensemble of wrappers is proposed and

Drug Critical Limits for Urgent Physician Notification
Clinical Pharmacology &Therapeutics, EarlyView.Critical limits represent quantitative decision thresholds for drugs that require immediate clinician notification and potential life‐saving intervention. United States hospitals lack a national standard for drug critical limits. We collected critical limits from 417 US hospitals across all 50 states and Washington, D.C.; of these, 411 maintained drug ...

Journal of Northwest Atlantic Fishery Science, 1997 Current estimates of harp seal (Phoca groenlandica) abundance indicate that the total population size in eastern Canada in 1994 was approximately 4.8 million (95% C.I. 4.1– 5.0 million) animals. To estimate the consumption of important fish prey by harp seals off the coast of Newfoundland and in the Gulf of St.

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Our shifting perspectives on the oceans [PDF]
, 2003 In the last 15 years new research findings have radically reshaped our understanding of human effects on ocean ecosystems. Here I describe five major shifts in perspective that reveal our impacts to be more severe and persistent than previously ...

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

What can size distributions within cohorts tell us about ecological processes in fish larvae?
Scientia Marina, 2009 Marine fish larvae are subject to variable environments, which is probably reflected in their growth and survival rates. Mortality rates are generally high and size-dependent.
