Fishing down the deep
A global crisis in marine fisheries was regarded with scepticism by many fisheries scientists as recently as 10 years ago. Today, however, few dispute worrying trends [Pitcher and Pauly 1998; Pitcher 2001; Pauly et al. 2002; Christensen et al. 2003; Hilborn et al. 2003; Pauly and Maclean 2003; Food and Agriculture Organization (FAO) 2004]. Historical data from marine ecosystems clearly suggest ...
متن کاملTiny SSD: A Tiny Single-shot Detection Deep Convolutional Neural Network for Real-time Embedded Object Detection
Object detection is a major challenge in computer vision, involving both object classification and object localization within a scene. While deep neural networks have been shown in recent years to yield very powerful techniques for tackling the challenge of object detection, one of the biggest challenges with enabling such object detection networks for widespread deployment on embedded devices ...
متن کاملEpidermal Growth Factor Receptor Down-Regulation Triggers Human Myoblast Differentiation
Initiation of human myoblast differentiation requires a negative shift (hyperpolarization) of the resting potential of myoblasts that depends on the activation of Kir2.1 potassium channels. These channels are regulated by a tyrosine phosphorylation. Using human primary myoblast culture, we investigated a possible role of various receptor tyrosine kinases in the induction of the differentiation ...
متن کاملTop-Down Regularization of Deep Belief Networks
Designing a principled and effective algorithm for learning deep architectures is a challenging problem. The current approach involves two training phases: a fully unsupervised learning followed by a strongly discriminative optimization. We suggest a deep learning strategy that bridges the gap between the two phases, resulting in a three-phase learning procedure. We propose to implement the sch...
متن کاملDo narcissists dislike themselves "deep down inside"?
Narcissism is a personality trait associated with an inflated, grandiose self-concept and a lack of intimacy in interpersonal relationships. A popular assumption is that narcissists’ positive explicit (conscious) self-views mask implicit (nonconscious) self-loathing. This belief is typically traced to psychodynamic theory, especially that of Kohut (1966; Morrison, 1983). Empirically, this view ...
