Discrimination of Saccharides by a Simple Array [PDF]

Chemistry - A European Journal, 2017
AbstractWe report the development of a two‐component probe system as fluorescence turn‐on assay of simple saccharides. The quenching of an anionic conjugated water‐soluble polymer by a cationic quencher has been reported previously. Three different boronic acid functionalized benzyl viologens and three conjugated polymers of the poly(aryleneethynylene)

Change in hippocampal theta activity with transfer from simple discrimination tasks to a simultaneous feature-negative task

Frontiers in Behavioral Neuroscience, 2014
It has been shown that solving a simple discrimination task (A+, B-) and a simultaneous feature-negative task (FN) (A+, AB-) uses the hippocampal-independent strategy. Recently, we showed that the number of sessions required for a rat to completely learn

Testing weight-based conditional discrimination in Goffin's cockatoos, Cacatua goffiniana. [PDF]

PLoS ONE
Discrimination learning tasks are a method for investigating species' perception of and associative learning with a particular stimulus. Goffin's cockatoos previously required surprisingly few trials to differentiate objects based on weight alone in a ...

Discriminating Between Simple and Perforated Appendicitis [PDF]

Journal of Surgical Research, 2012
Several studies have been performed in order to diagnose an acute appendicitis using history taking and laboratory investigations. The aim of this study was to create a model for the identification of a perforated appendicitis.All consecutive patients who have undergone an appendectomy in the Reinier de Graaf hospital between January 1, 2007 and July ...

Similar odor discrimination behavior in head-restrained and freely moving mice. [PDF]

PLoS ONE, 2012
A major challenge in neuroscience is relating neuronal activity to animal behavior. In olfaction limited techniques are available for these correlation studies in freely moving animals. To solve this problem, we developed an olfactory behavioral assay in

Estimation of Tactile Discriminatory Fitness in Hands of Public Transport Drivers

Journal of College of Medical Sciences-Nepal, 2020
Background: Public transport drivers are constantly being exposed to stimuli and are at risk of disorder of peripheral nervous system which can be further complicated by comorbidities.

Online vs. face-to-face experiments, a Matching to Sample procedure

Revista de Psicología y Ciencias del Comportamiento de la Unidad Académica de Ciencias Jurídicas y Sociales, 2022
The COVID-19 pandemic raised the need to adapt face-to-face experimental procedures to remote settings, seeking social distancing and confinement.

Transient decline in hippocampal theta activity during the acquisition process of the negative patterning task. [PDF]

PLoS ONE, 2013
Hippocampal function is important in the acquisition of negative patterning but not of simple discrimination. This study examined rat hippocampal theta activity during the acquisition stages (early, middle, and late) of the negative patterning task (A ...

Absence of abnormal vascular changes on prenatal imaging aids in differentiating simple uterine scar dehiscence from placenta accreta spectrum: a case series

Frontiers in Reproductive Health, 2023
Accurate prenatal discrimination between a simple, non-adherent uterine scar dehiscence with an underlying placenta and the severe end of the placenta accreta spectrum is problematic as the two can appear similar on prenatal imaging. This may lead to the

Learning simple texture discrimination filters [PDF]

2010 IEEE International Conference on Image Processing, 2010
Current texture analysis methods enable good discrimination but are computationally too expensive for applications which require high frame rates. This occurs because they use redundant calculations, failing in capturing the essence of the texture discrimination problem.
