Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, EarlyView.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery
Advanced Functional Materials, EarlyView.A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Advanced Functional Materials, EarlyView.Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...

Classical test theory (CTT) is the foundational theory of measurement of mental abilities. At its core, CTT describes the relationship between observed composite scores on a test and a presumed but unobserved “true” score for an examinee. CTT is called “classical” because it is thought to be the first operational use of mathematics to characterize this

Classical test theory (CTT) comprises a set of concepts and methods that provide a basis for many of the measurement tools currently used in health research. The assumptions and concepts underlying CTT are discussed. These include item and scale characteristics that derive from CTT as well as types of reliability and validity.

Classical test theory (CTT) rests on the assumption of a normal distribution of scores in some population and assumes scores are not at the extremes of the possible range. In CTT, a person’s observed test score is a sum of a true score and an error score.
