Aging and Cancer, EarlyView.ABSTRACT As global populations age, cancer is increasingly becoming a leading cause of morbidity and mortality among older adults, particularly in low‐ and middle‐income countries (LMICs). Despite accounting for the majority of new cancer cases and deaths, older individuals remain underrepresented in cancer research, clinical guidelines, and health ...

The structural complexity of perovskites
Physical Chemistry Chemical Physics, 2022Information theory is used to calculate structural complexities of various perovskite-type materials, showing that complexity scales with the size of the pseudocubic ReO3-type [BX3]n− network and available distortion schemes.

SCOTT COMPLEXITY OF COUNTABLE STRUCTURES
The Journal of Symbolic Logic, 2021AbstractWe define the Scott complexity of a countable structure to be the least complexity of a Scott sentence for that structure. This is a finer notion of complexity than Scott rank: it distinguishes between whether the simplest Scott sentence is $\Sigma _{\alpha }$ , $\Pi _{\alpha }$ , or $\mathrm {d-}\Sigma _{\alpha }$ .

REDUCTION OF STRUCTURAL COMPLEXITY
IFAC Proceedings Volumes, 1992Abstract The identification of weakly coupled sub-systems often provides the basis for complex multi-variable control system design. Such identification is not always easy, and conventional methods of system reduction often make such an approach impossible.

On the Complex Structure of the Universe
Journal of Mathematical Physics, 1966A complex space—time is constructed from physical axioms. Both gravitational and electromagnetic fields are approximations to parts of a geometric object defined on this complex space, while other parts may represent strong and weak interactions. The intersections of the singularities of the three independent geometric invariants are identified as ...

Structuring complex requirements
ACM SIGSOFT Software Engineering Notes, 2007Sets of requirements that analysts are dealing with are often big and complex. That makes requirements structuring one of the most important activities in requirements engineering, because of how requirements are structured and presented directly impacts the requirements development process and the quality of requirements.

Current Opinion in Structural Biology, 2005
Adenovirus has, for a long time, been a model system for understanding complex virus structure, assembly and interference in host cell processes. Recent structures of adenoviral capsid proteins critical for cell entry have given new insights into both interactions with host cell receptors and inter-capsid protein interactions, which determine the ...

The complexity of control structures and data structures
Proceedings of seventh annual ACM symposium on Theory of computing - STOC '75, 1975The running time or computational complexity of a sequential process is usually determined by summing weights attached to the basic operations from which the process is derived. In practice, however, the complexity is often limited by how efficiently it can access its data structures and how efficiently it can control program flow.

We consider a non-standard parametrization, where, forproblems consisting of a combinatorial structure and a number, we parameterizeby the combinatorial structure, rather than by the number.For example, in the Short-Nondeterministic-Halt problem, which is todetermine if a nondeterministic machine M accepts the empty string int steps, we parameterize by

Structure of ‘Complex’ Phospholipids
Nature, 1966COLLINS has given evidence for the presence of ‘complex’ phospholipids in animal tissues, and he suggested that they contained a phosphate triester group. He further suggested that they break down on silicic acid to give moieties having the currently accepted structures of the known phospholipids1,2.
