The program-substitution in algorithmic logic and algorithmic logic with non-deterministic programs

open access: yes, 1984
An extension of algorithmic logic is considered, i.e., a program substitution operator is introduced. For three different algorithmic logics (original with iterative quantifiers, extended with classical quantifiers and nondeterministic) it is proved that program substitution does not lead outside the provable formulae.

Post‐Translational Modified Neoantigens in Autoimmune Diseases: Challenges of Immune Tolerance

open access: yesAdvanced Science, EarlyView.
Autoimmune diseases have a high incidence and disability rate. The pathogenesis of autoimmune diseases involves the interaction among genetic factors, environmental factors, and immune disorders. The post‐translational modified neoantigens are the key nodal of these three factors. And these post‐translational modified neoantigens, after being presented

Cut‐Enabled Mechanical Metamaterials for Multimodal and Reprogrammable Static Nonreciprocity

open access: yesAdvanced Science, EarlyView.
Cut‐enabled mechanical metamaterials are designed to overcome the challenge of obtaining multiple and reprogrammable static nonreciprocal modes in a single microstructural topology. It offers a pathway to synthesize multiple nonreciprocal modes and control the nonreciprocal responses, enhancing the functionality of metamaterials.

Wide‐/Narrow‐Bandgap Heterojunction for High Performance Differential Photodetector with Tunable Response

open access: yesAdvanced Science, EarlyView.
A differential photodetector is developed by applying the unique characteristics of a wide‐/narrow‐bandgap semiconductor heterojunction. The mechanism based on band alignment enables high detectivity and high bandwidth with tunable photoresponse.

Controllable Preparation of Millimeter‐Scale In‐Plane Charged Domain Wall in a Lead‐Free Ferroelectric Film

open access: yesAdvanced Science, EarlyView.
This study presents an effective method for fabricating millimeter‐scale continuous in‐plane head‐to‐head charged domain walls by controlling the growth of the Na0.5Bi0.5TiO3 film. The formation of antiphase boundaries plays a crucial role in stabilizing the charged domain walls. Atomic‐scale insights reveal that the dynamic coupling among polarization,
