Conductive media in which ions carry charge through a solution are foundationally important to batteries, supercapacitors, and ionotronic devices. Shifts in ion mobility imposed by physical changes in the solution can dynamically impact the conductivity of the medium. This paper reports a class of…

Polymer-polyoxometalate (POM) systems represent an emergent class of functional hybrid materials. However, the pH-dependent stability of POMs limits their scope in water. We show here that the water-mediated, so-called superchaotropic, binding of α-Keggin POMs to a non-ionic biopolymer, hydroxypropylcellulose (HPC), i)…

People often switch tasks when attention wanes or an alternative task becomes more appealing. Such choices may reflect different control modes that may vary with working memory (WM) capacity. This study tested whether momentary attentional lapses prospectively predict voluntary task switching and whether this…

Cognitive Flexibility (CF) is the ability to switch between tasks, even under conditions when the need to switch is not explicitly cued. While the prefrontal cortex and its interaction with subcortical regions are considered central to CF, a key question remains: what are the underlying computational mechanisms that…

Metal-insulator-transition (MIT) materials are promising candidates for switchable electronics, neuromorphic hardware, and reconfigurable photonics, yet experimentally verified examples remain limited and the underlying mechanisms are often complex. We argue that generative AI for MIT discovery should move beyond the…

Phylogenetic comparisons suggest that behavioral flexibility facilitates success in urban environments. It remains less clear whether urbanization fosters cognitive skills that require flexibility, or whether successful individuals in urban environments simply apply pre-evolved skills to solve new problems. To…

The integration of ferroelectric (FE) and antiferromagnetic (AFM) orders in twodimensional (2D) materials provides a promising avenue for the nonvolatile control of coupled spin and valley degrees of freedom, a capability central to advancing spinvalleytronics. However, realizing a single material system where these…

Stimulus-responsive control of intermolecular interactions in multicomponent systems is a grand challenge in supramolecular chemistry and materials science. Herein, we demonstrate a stimulus-responsive miscibility switching in a two-component material composed of a functional molecular liquid (FML) and a pillar[5]arene…

This paper develops an embedding-based approach to solve switched optimal control problems (SOCPs) with an arbitrary number of subsystems. Initially, the discrete switching signal is represented by a set of binary variables, encoding each mode in binary format. An embedded optimal control problem (EOCP) is then…

Many everyday activities entail searching for multiple desired items and can be conceptualised as foraging. They require mental effort to keep each item in memory, while searching. An instantiation of such activities in experimental psychology is visual foraging, where people search for multiple target categories among…

Adaptive behavior in high-stakes, multitasking environments requires flexible switching between tasks with changing circumstances. However, task switching has typically been studied using static, simple, and unnoisy stimuli that are unrepresentative of most real-world operational environments. Here, we developed the…

Visual short-term memory (vSTM) refers to the subset of the cognitive system responsible for storing visual information over short periods of time. While much research has focused on its capacity limitations, less is known about how vSTM operates in dynamic environments where priorities shift across feature dimensions.…

Cold standby 1-out-of-n redundant systems are well-established models in system reliability engineering. To date, reliability analyses of such systems have predominantly assumed exponential, Erlang, or Weibull failure distributions for their components. The Lindley distribution and its generalizations represent a…

Ferroelectricity in ultrathin films, characterized by robust switchable out-of-plane polarization, is key to next-generation nanoelectronics. Although the macroscopic theory of ferroelectricity suggests that ferroelectricity is inevitably suppressed as the film thickness decreases, recent studies have demonstrated…

The benefits of routines for daily functioning are widely acknowledged, yet, despite their apparent importance, methods for quantifying routine maintenance and the causes of their disruption remain lacking. Here, we propose a novel means of defining and quantifying routines (transition entropy). Using the transition…

The complex aetiology of pancreatic ductal adenocarcinoma (PDAC), together with its desmoplastic and hypoxic microenvironment, hinders effective treatment and contributes to its rapid lethality^1^. Using a reversibly switchable genetic mouse model that closely recapitulates human PDAC phenotype progression, we…

Instruction-based learning (IBL) is an essential human skill, enabling flexible and efficient application of novel rules. Previous studies focused on instructions specifying affirmative (or positive) stimulus-response (S-R) rules (i.e., if condition A, then execute action X). Despite their frequent occurrence in our…

Adaptive agents do not always regulate under the same timing conditions. Sometimes stabilization can begin before a disturbance has fully entered the internal state; at other times the agent can only recover after disruption has taken hold. A simple expectation is that an agent moving between these conditions should…

Behavioral strategies can change in response to environmental and internal states, either gradually or abruptly, enabling flexible adaptation. Such strategy regulation is central to meta-learning, the ability to learn to learn. Previous studies analyzed temporal or condition-dependent strategy change using models and…
