Human activity recognition using data from wearable sensors, and more recently, mobile and smartphone sensors , is a widely researched problem. In this study, we explore the detection of human activities (walk, run, jog, climb stairs up, climb stairs down, stand still) from data acquired using smartphone sensors, accelerometer, gyroscope and magnetometer.(More)
Common bean (Phaseolus vulgaris L.) is a good source of protein, vitamins, minerals and complex carbohydrates. The objective was to compare protein profile, including anti-nutrient proteins, and potential bioactive peptides of improved common bean cultivars grown in Mexico and Brazil. Bean protein isolates (BPI) were prepared from 15 common bean cultivars(More)
The aim was to optimize the production of bioactive peptides from black bean (Phaseolus vulgaris L.) protein isolate and to determine their biological potential using biochemical and in silico approaches. Protein fractions were generated using eight commercially available proteases after 2, 3 and 4 h and 1:20, 1:30 and 1:50 enzyme/substrate (E/S) ratios.(More)
BACKGROUND Diabetes and hypertension are diseases affecting a high proportion of the world population; the use of food-based products such as common bean peptides may contribute to reduce the risk of complications associated to chronic diseases. The aim was to produce and characterize peptides from common bean protein isolates and evaluate their potential(More)
Joint inference approaches such as Integer Linear Programming (ILP) and Markov Logic Networks (MLNs) have recently been successfully applied to many natural language processing (NLP) tasks, often outperforming their pipeline counterparts. However, MLNs are arguably much less popular among NLP researchers than ILP. While NLP researchers who desire to employ(More)
An-ever increasing number of social media websites, electronic newspapers and Internet forums allow visitors to leave comments for others to read and interact. This exchange is not free from participants with malicious intentions, which do not contribute with the written conversation. Among different communities users adopt strategies to handle such users.(More)
The development of resistance to insecticides by the vector of malaria and the increasingly faster appearance of resistance to antimalarial drugs by the parasite can dangerously hamper efforts to control and eradicate the disease. Alternative ways to treat this disease are urgently needed. Here we evaluate the in vitro effect of direct current (DC)(More)
Black beans contain anthocyanins that could be used as colorants in foods with associated health benefits. The objective was to optimize anthocyanins extraction from black bean coats and evaluate their physicochemical stability and antidiabetes potential. Optimal extraction conditions were 24% ethanol, 1:40 solid-to-liquid ratio and 29°C (P<0.0001). Three(More)
Markov Logic Networks, a joint inference framework that combines logical and probabilistic representations, enable effective modeling of the dependencies that exist between different instances of a data sample. While its ability to capture relational dependencies makes it an ideal framework for predicting the structures inherent in many natural language(More)
