A General Framework for Multi-focal Image Classification and Authentication: Application to Microscope Pollen Images [PDF]
arXiv, 2015 In this article, we propose a general framework for multi-focal image classification and authentication, the methodology being demonstrated on microscope pollen images. The framework is meant to be generic and based on a brute force-like approach aimed to be efficient not only on any kind, and any number, of pollen images (regardless of the pollen type)

The Pollen of the Cherry [PDF]
Nature, 1876 THE practice of the indefinite reproduction of woodcuts by means of cliches has frequently given rise to the repetition of erroneous drawings in one scientific text-book after another. Botanical text-books seem to have suffered especially in this way, in consequence of the great dearth of new and original illustrations by which they are characterised ...

Interaction Between Actin and Microtubules During Plant Development
Cytoskeleton, EarlyView.ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Cytometry Part A, EarlyView.ABSTRACT Artificial intelligence (AI) surpasses human accuracy in identifying ordinary objects, but it is still challenging for AI to be competitive in pollen grain identification. One reason for this gap is the extensive trait variation in pollen grains.

How to do a clinical trial? Recommendations from the aerobiological point of view
World Allergy Organization Journal, 2019 Background: Allergy immunotherapy is still the only treatment of pollen allergy, providing a long-term effect. Clinical trials with pollen allergic patients are in need of validated, high quality pollen data and forecasts in order to grant comparability ...

The Depositional Record, EarlyView.A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

A Multi-Variate Triple-Regression Forecasting Algorithm for Long-Term Customized Allergy Season Prediction [PDF]
arXiv, 2020 In this paper, we propose a novel multi-variate algorithm using a triple-regression methodology to predict the airborne-pollen allergy season that can be customized for each patient in the long term. To improve the prediction accuracy, we first perform a pre-processing to integrate the historical data of pollen concentration and various inferential ...
