Cell turnover in the “resting” human breast: influence of parity, contraceptive pill, age and laterality [PDF]

open access: yesBritish Journal of Cancer, 1982
Morphological identification of cell multiplication (mitosis) and cell deletion (apoptosis) within the lobules of the "resting" human breast is used to assess the response of the breast parenchyma to the menstrual cycle. The responses are shown to have a biorhythm in phase with the menstrual cycle, with a 3-day separation of the mitotic and apoptotic ...

Collagen concentration and biomechanical properties of samples from the lower uterine cervix in relation to age and parity in non-pregnant women

open access: yesReproductive Biology and Endocrinology, 2010
Background During normal pregnancy the cervix has a load bearing function. The cervical tissue consists mainly of an extracellular matrix (ECM) rich in collagen; important for the biomechanical properties. The aim of the present study was to evaluate how

Low-Density Parity-Check Codes From Transversal Designs With Improved Stopping Set Distributions [PDF]

open access: yes, 2013
This paper examines the construction of low-density parity-check (LDPC) codes from transversal designs based on sets of mutually orthogonal Latin squares (MOLS). By transferring the concept of configurations in combinatorial designs to the level of Latin

The Small Stellated Dodecahedron Code and Friends [PDF]

open access: yes, 2018
We explore a distance-3 homological CSS quantum code, namely the small stellated dodecahedron code, for dense storage of quantum information and we compare its performance with the distance-3 surface code.

The mutational landscape of the adult healthy parous and nulliparous human breast

open access: yesNature Communications, 2023
The accumulation of somatic mutations in healthy human tissues has been extensively characterized, but the mutational landscape of the healthy breast is still poorly understood.

Phased burst error-correcting array codes [PDF]

open access: yes, 1993
Various aspects of single-phased burst-error-correcting array codes are explored. These codes are composed of two-dimensional arrays with row and column parities with a diagonally cyclic readout order; they are capable of correcting a single burst error ...

Coherence onset in PT-symmetric organic microcavities: towards directional propagation of light

open access: yesJournal of the European Optical Society-Rapid Publications, 2022
For the investigation of non-Hermitian effects and physics under parity-time (PT) symmetry, photonic systems are ideal model systems for both experimental and theoretical research.

Plasmodium falciparum exposure in utero, maternal age and parity influence the innate activation of foetal antigen presenting cells

open access: yesMalaria Journal, 2009
Background Malaria in pregnancy is associated with immunological abnormalities in the newborns, such as hampered T-helper 1 responses and increased T-regulatory responses, while the effect of maternal Plasmodium falciparum infection on foetal innate ...
