C$^3$ache: Accelerating World Action Models with Cross Inference Chunk Cache

Announce Type: new Abstract: World Action Models (WAMs) generalize better than standard Vision-Language-Action (VLA) policies to novel motions and environments, because a video-modeling objective lets them learn from abundant unlabeled video rather than scarce labeled robot demonstrations. This generalization is computationally expensive. To complete a task, a WAM runs over multiple inference chunks, and each chunk requires a costly denoising process.

Falls Induced by Optogenetic Inhibition of Basal Forebrain Cholinergic Projections after Dorsomedial Striatal Dopamine Depletion in a Dual Disruption Model of Falling Vulnerability in Parkinson Disease

Falls are a common and debilitating feature of Parkinson's Disease (PD) patients. Prefrontal acetylcholine (ACh) deficits, as well as nigrostriatal dopamine deficits, are implicated in vulnerability to falls. PD patients with loss of cortical ACh and associated cognitive dysfunction experience a higher rate of falls than PD patients without cortical ACh loss.

Spontaneous and stimulus-driven arousal produce distinct acetylcholine dynamics across sensory and prefrontal cortex

Acetylcholine (ACh) release from the basal forebrain has traditionally been viewed as a slow, spatially diffuse signal regulating cortical arousal across sleep and wakefulness. Recent characterizations with higher resolution optical sensors have revealed rapid, local cholinergic modulation supporting dynamic changes in sensory processing, associative learning, and behavioral state. However, sensory events that recruit cortical ACh often also change arousal and evoke movements, making it...

Arteriolar GMP signaling revealed by FRET-based real-time measurement in vivo

cGMP evokes arteriolar vasorelaxation and is generated in smooth muscle by the soluble guanylyl cyclase (sGC) stimulated by endothelial NO. Phosphodiesterases (PDEs) degrade cGMP and may contribute in diameter regulation. We examined arteriolar cGMP levels in real-time in vivo upon NO and acetylcholine (ACh) and effects of PDE inhibition.

19-year-old almost died after sharing drink with friends at Popworld

19-year-old almost died after sharing drink with friends at Popworld Lilly Williamson spent eight days in intensive care A teenager "almost died" from meningitis after she shared drinks with her friends on a night out in Popworld. Lily Williamson, 19, contracted meningococcal meningitis group B (MenB), causing sepsis and was left unable to move following a night of clubbing with her friends in Reading. She started getting aches and pains and was taken to the doctor by her mum when she...

Major League Baseball's Over-35 Hitters Face Steepest Production Drop-Off in Decades

Nolan Arenado was slugging his way through the month of May when the Arizona Diamondbacks third baseman woke up one morning with an ailment that's familiar to those who felt invincible in their 20s but have advanced to their mid-to-late 30s. Not enough to keep him out of the lineup. But it was one of those inexplicable moments that comes with being an aging Major League Baseball player — threatening to derail a hot streak for an eight-time All-Star who just turned 35."There's more aches and...

Fear of recurrence: How immune memory helps cancer survivors face their worst nightmare

Every year the world observes National Cancer Survivors Month in June, celebrating the growing number of people who have successfully completed cancer treatment and are building lives beyond their diagnosis. For many survivors, however, the end of treatment does not always bring complete peace of mind. Even years later, routine scans, follow-up appointments or unexplained aches can revive a lingering question: What if the cancer comes back?
