Warren Buffet once said, "Only when the tide goes out do you discover who's been swimming naked." You can cover over a host of sins when times are good, but bad or unsafe practices will be exposed when times are rough. Time and experience have borne out the accuracy of this witticism in the financial arena -- and we're now seeing its applicability to the intersection of infosec and COVID-19.

Statistical regularities in natural sounds facilitate the perceptual segregation of auditory sources, or streams. Repetition is one cue that drives stream segregation in humans, but the neural basis of this perceptual phenomenon remains unknown. We demonstrated a similar perceptual ability in animals by training ferrets of both sexes to detect a stream of repeating noise samples (foreground) embedded in a stream of random samples (background). During passive listening, we recorded neural activity in primary auditory cortex (A1) and secondary auditory cortex (posterior ectosylvian gyrus, PEG). We used two context-dependent encoding models to test for evidence of streaming of the repeating stimulus. The first was based on average evoked activity per noise sample and the second on the spectro-temporal receptive field. Both approaches tested whether differences in neural responses to repeating versus random stimuli were better modeled by scaling the response to both streams equally (global gain) or by separately scaling the response to the foreground versus background stream (stream-specific gain). Consistent with previous observations of adaptation, we found an overall reduction in global gain when the stimulus began to repeat. However, when we measured stream-specific changes in gain, responses to the foreground were enhanced relative to the background. This enhancement was stronger in PEG than A1. In A1, enhancement was strongest in units with low sparseness (i.e., broad sensory tuning) and with tuning selective for the repeated sample. Enhancement of responses to the foreground relative to the background provides evidence for stream segregation that emerges in A1 and is refined in PEG.

SIGNIFICANCE STATEMENT To interact with the world successfully, the brain must parse behaviorally important information from a complex sensory environment. Complex mixtures of sounds often arrive at the ears simultaneously or in close succession, yet they are effortlessly segregated into distinct perceptual sources. This process breaks down in hearing-impaired individuals and speech recognition devices. By identifying the underlying neural mechanisms that facilitate perceptual segregation, we can develop strategies for ameliorating hearing loss and improving speech recognition technology in the presence of background noise. Here, we present evidence to support a hierarchical process, present in primary auditory cortex and refined in secondary auditory cortex, in which sound repetition facilitates segregation.

Smallholders and people living in rural areas in Africa grow a huge variety of edible plants other than rice, wheat or maize. These crops, including the African yam bean, have long been neglected although they represent an excellent alternative food supplement to most diets. Grown in pockets of tropical Central, West and East Africa, the African yam bean (Sphenostylis stenocarpa) [...]

Migration has always existed. It has been a means to reunite with family, to find better jobs, to have a new experience or to start a better life. In 2015, the number of people migrating was up to 1 out of every 7 people in the world.   When it is a choice, migration can be a good way to spread [...]

The Covid-19 shock is placing enormous strains on corporates cash buffers. Corporate financial statements from 2019 suggest that 50% of firms do not have sufficient cash to cover total debt servicing costs over the coming year. Credit lines could provide firms with additional liquidity. On average undrawn credit stood around 120% of debt servicing costs at end 2019. However, access is uneven and banks may be reluctant to renew or extend them in the current environment. Sticky operating expenses result in many firms running operating losses, placing an additional burden on cash buffers. Estimates indicate that following a 10% drop in revenues, operating expenses only fall by 6% on average. Simulations suggest that if revenues fall by 25% in 2020, then closing the entire funding gap with debt would raise firm leverage by around 10 percentage points.
