acute bee paralysis virus (abpv) is a small single stranded rna virus recently classified within the family dicistroviridae, genus cripavirus. here, we describe the first study of abpv in unhealthy bee colonies, which has been an unusual loss in adult bee population and significant honey bee mortality during the year. the aim of this study was evaluation of abpv infection in honey bee colonies ...

The increasing diversity and heterogeneity of molecular data for phylogeny estimation has led to development of complex models and model-based estimators. Here, we propose a penalized likelihood (PL) framework in which the levels of complexity in the underlying model can be smoothly controlled. We demonstrate the PL framework for a four-taxon tree case and investigate its properties. The PL fra...

This article addresses the impact that colored noise, temporal filtering, and temporal detrending have on the fMRI analysis situation. Specifically, it is shown why the detection of event-related designs benefit more from pre-whitening than blocked designs in a colored noise structure. Both theoretical and empirical results are provided. Furthermore, a novel exploratory method for producing dri...

Biofouling is generally undesirable for many applications. An overview of the medical, marine and industrial fields susceptible to fouling is presented. Two types of fouling include biofouling from organism colonization and inorganic fouling from non-living particles. Nature offers many solutions to control fouling through various physical and chemical control mechanisms. Examples include low d...

Honey bees face new challenges, ranging from climate crisis to emerging pathogens such as Vairimorpha (Nosema) ceranae that synergistically cause a syndrome designated colony collapse disorder (CCD). This study employed metataxonomic approach in order investigate if V. affects gut microbiota (bacteria and fungi) of adult A. mellifera honey well bee bread (BB) stored colonies demonstrating sever...

Advanced thought and planning are required when preparing for podiatric surgery. In addition to appropriate procedure selection and follow-up, perioperative management has a key role in patient and physician satisfaction. Neglect of this aspect of podiatric care can also be a source of malpractice. This article analyzes many of the common medical treatments currently employed and makes recommen...

We propose a methodology useful for food services, allowing contribution margins to be optimized. This is based on statistical tools, inventory models and financial indicators. To reduce the gap between theory and practice, we apply this methodology to the case study of a Chilean company to show its potential. We conduct a real-world demand data analysis for perishable and non-perishable produc...

Propolis is a bee product, composed mainly of plant resins and beeswax, therefore its chemical composition varies due to the geographic and plant origins of these resins, as well as the species of bee. Brazil is an important supplier of propolis on the world market and, although green colored propolis from the southeast is the most known and studied, several other types of propolis from Apis me...

Automated and accurate classification of magnetic resonance (MR) brain images is a hot topic in the field of neuroimaging. Recently many different and innovative methods have been proposed to improve upon this technology. In this study, we presented a hybrid method based on forward neural network (FNN) to classify an MR brain image as normal or abnormal. The method first employed a discrete wav...
