Jensen ${\Delta }_n^1$ Reals by Means of ZFC and Second-Order Peano Arithmetic

Axioms
It was established by Jensen in 1970 that there is a generic extension L[a] of the constructible universe L by a non-constructible real a∉L, minimal over L, such that a is Δ31 in L[a].

Characterizations of Weakly Approximately Primary Submodules in Some Types of Modules

Tikrit Journal of Pure Science, 2021
Our aim in this note is to introduce several characterizations of weakly approximately primary submodules in class of multiplication modules. Furthermore, we characterized weakly approximately primary submodules by theirs resudule in the class of ...

NORMAL FUNCTIONS FOR ALGEBRAICALLY TRIVIAL CYCLES ARE ALGEBRAIC FOR ARITHMETIC REASONS

Forum of Mathematics, Sigma, 2019
For families of smooth complex projective varieties, we show that normal functions arising from algebraically trivial cycle classes are algebraic and defined over the field of definition of the family.

Effects of Cancer Treatment on Somatosensory and Nociceptive Processing in Children and Adolescents: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.
