Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Synchronizing to the Environment: Information Theoretic Constraints on Agent Learning

open access: yes, 2001
We show that the way in which the Shannon entropy of sequences produced by an information source converges to the source's entropy rate can be used to monitor how an intelligent agent builds and effectively uses a predictive model of its environment.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

open access: yesAdvanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

Filtered derivative with p-value method for multiple change-points detection [PDF]

open access: yes, 2009
This paper deals with off-line detection of change points for time series of independent observations, when the number of change points is unknown. We propose a sequential analysis like method with linear time and memory complexity.

Ecologically‐Valid Emotion Signatures Enhance Mood Disorder Diagnostics

open access: yesAdvanced Science, EarlyView.
This study identifies ecologically‐valid Divergent Emotional Functional Networks (DEFN), derived from dynamic functional connectivity during naturalistic movie watching. The DEFN reliably enhances diagnostic accuracy for mood disorders, including major depressive and bipolar disorders, demonstrating strong reproducibility across demographic factors and

Modifying Glucose Metabolism Reverses Memory Defects of Alzheimer's Disease Model at Late Stages

open access: yesAdvanced Science, EarlyView.
Using spatial transcriptomics, we show that ferul enanthate (SL‐ZF‐01) reverses episodic‐like memory deficits in aged, but not young, Alzheimer’s disease (AD) mice. SL restores glucose metabolism and Glucose Transporter 1/3 expression via an ‘Aging‐AD‐Rescue’ pattern, rescuing deficits seen in aged AD mice.
