ranger: A Fast Implementation of Random Forests for High Dimensional Data in C++ and R [PDF]

open access: yes, 2017
We introduce the C++ application and R package ranger. The software is a fast implementation of random forests for high dimensional data. Ensembles of classification, regression and survival trees are supported.

Consolidation of an olfactory memory trace in the olfactory bulb is required for learning-induced survival of adult-born neurons and long-term memory. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: It has recently been proposed that adult-born neurons in the olfactory bulb, whose survival is modulated by learning, support long-term olfactory memory.

Protecting and rescuing the effectors: roles of differentiation and survival in the control of memory T cell development

open access: yesFrontiers in Immunology, 2013
Vaccines, arguably the single most important intervention in improving human health, have exploited the phenomenon of immunological memory. The elicitation of memory T cells is often an essential part of successful long-lived protective immunity.

The Capabilities of a Perturbed Toric Code as a Quantum Memory [PDF]

open access: yes, 2011
We analyze the effect of typical, unknown perturbations on the 2D toric code when acting as a quantum memory, incorporating the effects of error correction on read-out.

The Survival Advantage: Underlying Mechanisms and Extant Limitations

open access: yesEvolutionary Psychology, 2015
Recently, researchers have begun to investigate the function of memory in our evolutionary history. According to Nairne and colleagues (e.g., Nairne, Pandeirada, and Thompson, 2008 ; Nairne, Thompson, and Pandeirada, 2007 ), the best mnemonic strategy ...

Survival circuits and risk assessment [PDF]

open access: yes, 2018
Risk assessment (RA) behaviour is unusual in the context of survival circuits. An external object elicits eating, mating or fleeing; but conflict between internal approach and withdrawal tendencies elicits RA-specific behaviour that scans the environment

Cultural Heritage and its survival: image, memory, archetype

open access: yesConservar Património, 2016
Over the last few years, we have been witnessing countless disaster situations (i.e. fires, floods, earthquakes...) and the consequent degradation, disappearance and irreparable damage to heritage assets that bear fundamental witness to history, memory ...

Protective effector memory CD4 T cells depend on ICOS for survival. [PDF]

open access: yesPLoS ONE, 2011
Memory CD4 T cells play a vital role in protection against re-infection by pathogens as diverse as helminthes or influenza viruses. Inducible costimulator (ICOS) is highly expressed on memory CD4 T cells and has been shown to augment proliferation and ...

Modulation of neurotrophic signaling pathways by polyphenols [PDF]

open access: yes, 2015
Polyphenols are an important class of phytochemicals, and several lines of evidence have demonstrated their beneficial effects in the context of a number of pathologies including neurodegenerative disorders such as Alzheimer's and Parkinson's disease. In
