Exploring factors that influence the behavior response to novel object tests in young thoroughbred horses: investigating sex, test site and auction history.
Front Vet Sci

Institute for Animal Welfare, Animal Behavior and Laboratory Animal Science, Freie Universität Berlin, Berlin, Germany.
Introduction: The novel object test is one of the three most common fear tests in veterinary science and employed in several different species. Although having been applied in several different studies in horses, it is surprising that there is no standardized test procedure available for these kinds of tests.
Methods: This study investigated the performance of the novel object test on 42 young Thoroughbred horses to determine the effect of sex (mare or stallion), test sites (round pen or paddock) and whether the horses had previously participated in an auction or not on the behavior during the novel object test.
Efficient nonlinear function approximation in analog resistive crossbars for recurrent neural networks.

Analog In-memory Computing (IMC) has demonstrated energy-efficient and low latency implementation of convolution and fully-connected layers in deep neural networks (DNN) by using physics for computing in parallel resistive memory arrays. However, recurrent neural networks (RNN) that are widely used for speech-recognition and natural language processing have tasted limited success with this approach. This can be attributed to the significant time and energy penalties incurred in implementing nonlinear activation functions that are abundant in such models.

Predictive updating of an object's spatial coordinates from pre-saccade to post-saccade contributes to stable visual perception. Whether object features are predictively remapped remains contested. We set out to characterise the spatiotemporal dynamics of feature processing during stable fixation and active vision.

Introduction: Prolonged sitting can acutely reduce working memory (WM) in individuals with overweight and obesity (OW/OB) who show executive function deficits. Interrupting prolonged sitting with brief PA bouts may counter these effects. However, the benefits of such interventions on behavioral and neuroelectric indices of WM and whether neurocognitive responses are associated with postprandial glycemic responses in young and middle-aged adults with OW/OB remain unknown.

Background: PTB (PTB) remains a leading cause of neonatal morbidity and mortality. Cerclage for short cervical length (CL) ≤25mm in singletons with a history of spontaneous PTB is associated with decreased neonatal morbidity/mortality. Both vaginal progesterone and cerclage individually have level 1 evidence supporting benefit in prevention of PTB in pregnancies complicated by short CL, however there is a paucity of level 1 evidence regarding the potential benefit of cerclage with progesterone compared to progesterone alone for short CL ≤25mm in singletons without a history of spontaneous PTB.
