Teff (Eragrostis tef) processing,utilization and future opportunities: a review

The demand for food production has been constantly increasing due to rising population. In developed countries, for example, the emergence of regional production of old grains that are rarely utilized, along with the production of commonly consumed grains, has gained importance in recent years. These grains, known collectively as ancient or heirloom grains, have offered both farmers and consumers novel ways of cultivation and products with interesting taste, characteristics and nutritional value. Among the 30 000 plant species known, only five cereals currently provide more than 50% of the world's energy intake – bread wheat (Triticum aestivum), rice (Oryza sativa), sorghum (Sorghum bicolor), millets (Panicum sp.) and maize (Zea mays). The excessive utilization of these selected species has a great potential to cause genetic losses and difficulty in bridging future agricultural demands. Teff (Eragrostis tef), an ancient grain extensively cultivated in countries like Eritrea and Ethiopia, provides promising alternatives for new food uses since its nutritional value is significantly higher than most others cereal grains. The absence of gluten allows flexibility in food utilization since it can be directly substituted to gluten-containing products. The grain also offers an excellent balance of essential amino acids and minerals, which can fulfil the recommended daily intake and eliminates the need for fortification and enrichment. This review provides a general overview of the physical properties and nutritional composition of teff grains related to processing and applications in the food and feed industries. The current status of teff utilization, as well as the challenges in production and commercialization, and future opportunities is presented and discussed.     

Multi-task learning for video anomaly detection

We propose a multi-task learning framework for video anomaly detection based on a novel pipeline. Our model contains two crossing streams, one stream employs the backbone of Attention-R2U-net for future frame prediction, while the other is designed based on an encoder–decoder network to reconstruct the input optical flow maps. In addition, the latent layers of the two streams are merged together and assigned with a Deep SVDD-based loss at each location individually. Through the combination of these three tasks, the two-stream-crossing pipeline can be trained end-to-end to provide a comprehensive evaluation for the anomaly targets. Experimental results on several popular benchmark datasets show that our model outperforms the state-of-the-art competing models, which can be applied to different types of anomalous targets and meanwhile achieves remarkable precision.

Developing an equitable and sustainable mobility strategy for Havana

The particular political, economic and social conditions of the state of Cuba, in the Caribbean, have created unique possibilities for the development of a sustainable transport system in its capital city, Havana. This paper reports on the outcomes of a project to identify the possibilities and priorities for a long-term strategy for equitable and sustainable mobility for Havana. This involved almost 100 participants from Cuba and the UK in the 12 months from June 2013.Overall, the study found a high degree of agreement amongst the transport policy community as to the three key transport issues facing Havana:

• •high level of unmet demand,
• •lack of available financing,
• •poor state of the transport system.

Perhaps more surprisingly, it also produced a near consensus amongst the participants that any future policy should seek to increase the quality of the public transport system by:

• •increasing levels of investment,
• •securing efficiency savings,
• •working ‘smarter’.

However, it also found that this unified view is challenged by a desire for the car market to be deregulated, which would engender a very different policy approach. A strategic choice is needed now, to determine whether Havana follows a North American-style trajectory of rapid growth in car use or a less car-dependent pathway.
