Phenotypic heterogeneity in lag reflects an evolutionarily stable bet-hedging strategy Open
Single-cell experiments in yeast reveal two distinct heritable phenotypes—’arresters’ and ‘recoverers’—when a clonal population experiences a negative shift in its growth environment. Recoverers exhibit a variable yet finite lag before res…

Adaptive algorithms for shaping behavior Open
Dogs and laboratory mice are commonly trained to perform complex tasks by guiding them through a curriculum of simpler tasks (‘shaping’). What are the principles behind effective shaping strategies? Here, we propose a teacher-student frame…

Manifold learning for olfactory habituation to strongly fluctuating backgrounds Open
Animals rely on their sense of smell to survive, but important olfactory cues are mixed with confounding background odors that fluctuate due to atmospheric turbulence. It is unclear how the olfactory system habituates to such stochastic ba…

LCC-Net: Swin transformer-CNN hybrid for enhanced land cover classification in natural disaster monitoring Open
Land cover classification (LCC) from satellite images is crucial in identifying and monitoring natural disasters, including cyclones, earthquakes, floods, and wildfires. Statistics reveal that accurate disaster classification from satellit…

PCOS Detection Using Machine Learning Open
Reproductive-age women worldwide suffer from metabolic problems, hormonal imbalance, and irregular menstruation due to PCOS. Complex symptoms of PCOS often lead to misdiagnosis or underdiagnosis, causing suffering and increasing the risk o…

Differential learning kinetics govern the transition from memorization to generalization during in-context learning Open
Transformers exhibit in-context learning (ICL): the ability to use novel information presented in the context without additional weight updates. Recent work shows that ICL emerges when models are trained on a sufficiently diverse set of ta…

The mechanistic basis of data dependence and abrupt learning in an in-context classification task Open
Transformer models exhibit in-context learning: the ability to accurately predict the response to a novel query based on illustrative examples in the input sequence. In-context learning contrasts with traditional in-weights learning of que…

Distinct information conveyed to the olfactory bulb by feedforward input from the nose and feedback from the cortex Open
Sensory systems are organized hierarchically, but feedback projections frequently disrupt this order. In the olfactory bulb (OB), cortical feedback projections numerically match sensory inputs. To unravel information carried by these two s…

Epistasis and evolution: recent advances and an outlook for prediction Open
As organisms evolve, the effects of mutations change as a result of epistatic interactions with other mutations accumulated along the line of descent. This can lead to shifts in adaptability or robustness that ultimately shape subsequent e…

Energy-positive soaring using transient turbulent fluctuations Open
Soaring birds gain energy from stable ascending currents or shear. However, it remains unclear whether energy loss due to drag can be overcome by extracting work from transient turbulent fluctuations. We designed numerical simulations of g…
