Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Design of a Biomimetic Spine for the Humanoid Robot

Abstract — This paper presents a prototype of 3 degrees-offreedom articulated spine for the doll-shaped humanoid robot Robota. This work follows an approach that emphasizes the need for a high human-likeliness in both the external features of the robot and in the kinematics of its motions to enhance human-robot interactions. The design of a spinal cord for our humanoid robot satisfies both criteria in providing offering a smooth human-like parallel means of bending forward and sideways.

Development of a miniature pair of eyes with camera for the humanoid robot robota

A growing trend in humanoid robotics tend at reducing the size of humanoids in order to lower their building costs. While growing small has its advantages, it also has drawbacks. In particular, providing miniature humanoids with the same sensorimotor capabilities as their grown-up peers is a challenge, both in terms of mechanics, electronics and control. The Robota project creates humanoids, whose size should match that of a commercial doll, so that they can be used as part of experiments with autistic children. Because these experiments measure the child’s ability to socially interact with others, it is fundamental to provide the robot with sensory capabilities, such as speech and vision, that are at the basis of these interactions. This paper presents the creation of a miniature pair of mobile eyes, mounted with miniature cameras to provide Robota with binocular and mobile vision. The system allows the robot to blink, to direct its gaze toward or away from its user and to track the user’s face.

Physical Connections and Cooperation in Swarm Robotics

We describe a new multi-robot system, named SWARM-BOTS, that exploits physical inter-connections to solve tasks that are impossible for a single robot

In vitro iron bioaccessibility and uptake from orange-fleshed sweet potato (Ipomoea batatas (L.) Lam.) clones grown in Peru.

Research to evaluate the potential of sweet potato to alleviate iron deficiency in affected human populations in developing countries is scarce. To partly fill this gap, we evaluated the bioaccessibility of iron in six sweet potato clones grown in two Peruvian environments, Satipo and San Ramon, following an in vitro gastro-intestinal digestion procedure. The bioaccessible iron content was clone-dependent and 1.7-fold higher in Satipo (5.15 g/g of fresh weight (FW)) as compared to San Ramon (3.04 g/g of FW). Aspects of iron bioavailability were then investigated using the Caco-2 cell model and ferritin synthesis as a marker, on two sweet potato clones after addition of an extrinsic source of iron to the digestion mixture.Results indicated that clone “CIP-194540.5” was presenting higher bioaccessible iron and lower phenolic contents and showed higher iron uptake as compared to clone “CIP-1055011.1” in both environments (91% vs. 24% in Satipo and 67% vs. 13% in San Ramon, respectively). These iron uptake values are higher than the ones previously reported for potato, which further stresses the use of sweet potato storage roots as part of a healthier diet in developing countries

In vitro bioaccessibility and bioavailability of iron from potatoes with varying Vitamin C, carotenoid, and phenolic concentrations

The purpose of this study was to compare the in vitro iron availability from diverse iron biofortified International Potato Center (CIP) potato clones grown in the Peruvian Andes and, thereby, to provide key information to breeders seeking to increase bioavailable iron from potato
