Multiferroic Quantum Criticality in a Proper Ferroelectric Quasi‐one‐dimensional Ising Antiferromagnet

open access: yesAdvanced Science, EarlyView.
Sr1−xBaxCo2V2O8 is established as a magnetic‐ion‐based proper displacive ferroelectric whose transition is continuously suppressed by Ba substitution to a ferroelectric quantum critical point. In the resulting quantum paraelectric regime, a transverse magnetic field induces magnetic quantum criticality, realizing multiferroic quantum criticality and ...

Thermal Shifts Dominate Single‐Gene Responses to Transcription‐Targeting Antibiotics

open access: yesAdvanced Science, EarlyView.
Thermal shifts reshape bacterial responses to transcription‐targeting antibiotics. In E. coli, temperature can dominate antibiotic‐induced genome‐wide expression, particularly outside 30°C–39°C, through changes in adenosine triphosphate (ATP), nucleoid organization, and drug‐target engagement.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Vine‐Inspired Soft Robotics: Materials, Actuations, and Emerging Applications

open access: yesAdvanced Science, EarlyView.
Vine‐inspired robots grow from the tip, enabling navigation through confined spaces with minimal disturbance. This Review summarizes material and actuation strategies for vine‐inspired growth, key functions including steering, retraction, attachment, branching, and variable stiffness, and emerging applications spanning medical intervention, confined ...

The compiler compiler

Annual Review in Automatic Programming, 1963
Publisher Summary This chapter presents detailed specification of a system for describing the form and meaning of the statements in a phrase structure language, for example, a scientific autocode. Given such a description, the compiler compiler will generate a compiler for the language, that is, a program that can read and translate another program ...

Finding and Understanding Bugs in C Compilers

open access: yesACM SIGPLAN Notices, 2011
Compilers should be correct. To improve the quality of C compilers, we created Csmith, a randomized test-case generation tool, and spent three years using it to find compiler bugs.

Optimization aspects of compiler-compilers

ACM SIGPLAN Notices, 1970
A decade of experience with prototype versions of compiler-compilers, some of which have been successful and some of which have not been so successful, leads us to the conclusion that we can now engineer good compiler-compilers which can generate efficient compilers that generate efficient object code.

MUG1 - an incremental compiler-compiler

Proceedings of the annual conference on - ACM 76, 1976
MUG1 is a compiler generating system developed and implemented at the Technical University of Munich. The structure of the system and the concepts used in the compiler description are presented. Special emphasis is laid on the use of MUG1 as a tool for the incremental design of programming languages and the construction of their compilers in parallel.

A compiler---compiler system

Proceedings of the 1967 22nd national conference on -, 1967
To the author's knowledge three other operational compiler-compiler systems, whose strategy is similar to the scheme documented here, have been developed. The Feldman system [6, 7, 8] is a bounded context, syntax directed system. Syntax specifications are expressed in Floyd production language (FPL) and semantics are defined in Feldman semantic ...
